Population attributable fractions of modifiable risk factors for dementia: a systematic review and meta-analysis
Stephan BCM, Cochrane L, Kafadar AH, Brain J, Burton E, Myers B, Brayne C, Naheed A, Anstey KJ, Ashor AW and Siervo M
More than 57 million people have dementia worldwide. Evidence indicates a change in dementia prevalence and incidence in high-income countries, which is likely to be due to improved life-course population health. Identifying key modifiable risk factors for dementia is essential for informing risk reduction and prevention strategies. We therefore aimed to estimate the population attributable fraction (PAF) for dementia associated with modifiable risk factors.
Subcortical tau is linked to hypoperfusion in connected cortical regions in 4-repeat tauopathies
Roemer SN, Brendel M, Gnoerich J, Malpetti M, Zaganjori M, Quattrone A, Gross M, Steward A, Dewenter A, Wagner F, Dehsarvi A, Ferschmann C, Wall S, Palleis C, Rauchmann BS, Katzdobler S, Jaeck A, Stockbauer A, Fietzek UM, Bernhardt AM, Weidinger E, Zwergal A, Stoecklein S, Perneczky R, Barthel H, Sabri O, Levin J, Hoeglinger GU and Franzmeier N
4-repeat (4R) tauopathies are neurodegenerative diseases characterized by cerebral accumulation of 4R tau pathology. The most prominent 4R-tauopathies are progressive-supranuclear-palsy (PSP) and corticobasal-degeneration (CBD) characterized by subcortical tau accumulation and cortical neuronal dysfunction, as shown by PET-assessed hypoperfusion and glucose hypometabolism. Yet, there is a spatial mismatch between subcortical tau deposition patterns and cortical neuronal dysfunction, and it is unclear how these two pathological brain changes are interrelated. Here, we hypothesized that subcortical tau pathology induces remote neuronal dysfunction in functionally connected cortical regions to test a pathophysiological model that mechanistically links subcortical tau accumulation to cortical neuronal dysfunction in 4R tauopathies. We included 51 Aβ-negative patients with clinically diagnosed PSP variants (n=26) or Corticobasal Syndrome (CBS; n=25) who underwent structural MRI and 18F-PI-2620 tau-PET. 18F-PI-2620 tau-PET was recorded using a dynamic one-stop-shop acquisition protocol, to determine an early 0.5-2.5 min post-tracer-injection perfusion window for assessing cortical neuronal dysfunction, as well as a 20-40 min post-tracer-injection window to determine 4R-tau load. Perfusion-PET (i.e. early-window) was assessed in 200 cortical regions, and tau-PET was assessed in 32 subcortical regions of established functional brain atlasses. We determined tau epicenters as subcortical regions with highest 18F-PI-2620 tau-PET signal and assessed the connectivity of tau epicenters to cortical ROIs using a resting-state fMRI-based functional connectivity template derived from 69 healthy elderly controls from the ADNI cohort. Using linear regression, we assessed whether i) higher subcortical tau-PET was associated with reduced cortical perfusion and ii) whether cortical perfusion reductions were observed preferentially in regions closely connected to subcortical tau epicenters. As hypothesized, higher subcortical tau-PET was associated with overall lower cortical perfusion, which remained consistent when controlling for cortical tau-PET. Using group-average and subject-level PET data, we found that the seed-based connectivity pattern of subcortical tau epicenters aligned with cortical perfusion patterns, where cortical regions that were more closely connected to the tau epicenter showed lower perfusion. Together, subcortical tau-accumulation is associated with remote perfusion reductions indicative of neuronal dysfunction in functionally connected cortical regions in 4R-tauopathies. This suggests that subcortical tau pathology may induce cortical dysfunction, which may contribute to clinical disease manifestation and clinical heterogeneity.
European Autism GEnomics Registry (EAGER): protocol for a multicentre cohort study and registry
Bloomfield M, Lautarescu A, Heraty S, Douglas S, Violland P, Plas R, Ghosh A, Van den Bosch K, Eaton E, Absoud M, Battini R, Blázquez Hinojosa A, Bolshakova N, Bölte S, Bonanni P, Borg J, Calderoni S, Calvo Escalona R, Castelo-Branco M, Castro-Fornieles J, Caro P, Cliquet F, Danieli A, Delorme R, Elia M, Hempel M, Leblond CS, Madeira N, McAlonan G, Milone R, Molloy CJ, Mouga S, Montiel V, Pina Rodrigues A, Schaaf CP, Serrano M, Tammimies K, Tye C, Vigevano F, Oliveira G, Mazzone B, O'Neill C, Pender J, Romero V, Tillmann J, Oakley B, Murphy DGM, Gallagher L, Bourgeron T, Chatham C and Charman T
Autism is a common neurodevelopmental condition with a complex genetic aetiology that includes contributions from monogenic and polygenic factors. Many autistic people have unmet healthcare needs that could be served by genomics-informed research and clinical trials. The primary aim of the European Autism GEnomics Registry (EAGER) is to establish a registry of participants with a diagnosis of autism or an associated rare genetic condition who have undergone whole-genome sequencing. The registry can facilitate recruitment for future clinical trials and research studies, based on genetic, clinical and phenotypic profiles, as well as participant preferences. The secondary aim of EAGER is to investigate the association between mental and physical health characteristics and participants' genetic profiles.

Sawlani SP, Goldman JT, Babikian T, McArthur DL, Polster D, McCrea M, McAllister T, Giza CC, , , Ortega JD, Port N, Putukian M, McDevitt J, Giza CC, Goldman JT, Benjamin HJ, Buckley T, Kaminski TW, Clugston JR, Feigenbaum LA, Eckner JT, Mihalik JP, Anderson S, Master CL, Kontos AP, Chrisman SPO, Cameron K, Duma S and Miles CM
Mental health disorders are linked to prolonged concussion symptoms. However, the association of premorbid anxiety/depression symptoms with postconcussion return-to-play timelines and total symptom burden is unclear.
The effect of non-pharmacological prenatal interventions on fear of childbirth: an overview of systematic reviews and meta-analysis
Alizadeh-Dibazari Z, Maghalain M and Mirghafourvand M
During pregnancy and childbirth, alongside positive feelings, women undergo feelings such as fear of childbirth (FoC) and worry about its consequences, which could leave negative effects on the mother and her child during pregnancy, delivery, and postpartum. The study was carried out to determine the effectiveness of prenatal non-pharmacological interventions on reducing the FoC.
Abortion and mental health outcomes: A systematic review and meta-analysis
Littell JH, Young S, Pigott TD, Biggs MA, Munk-Olsen T and Steinberg JR
This is a protocol for a systematic review and meta-analysis of research on mental health outcomes of abortion. Does abortion increase the risk of adverse mental health outcomes? That is the central question for this review. Our review aims to inform policy and practice by locating, critically appraising, and synthesizing empirical evidence on associations between abortion and subsequent mental health outcomes. Given the controversies surrounding this topic and the complex social, political, legal, and ideological contexts in which research and reviews on abortion are conducted, it is especially important to conduct this systematic review and meta-analysis with comprehensive, rigorous, unbiased, and transparent methods. We will include a variety of study designs to enhance understanding of studies' methodological strengths and weaknesses and to identify potential explanations for conflicting results. We will follow open science principles, providing access to our methods, measures, and results, and making data available for re-analysis.
The Effectiveness of Virtual Reality-Based Training on Cognitive, Social, and Physical Functioning in High-Functioning Older Adults (CoSoPhy FX): 2-Arm, Parallel-Group Randomized Controlled Trial
Szczepocka E, Mokros Ł, Kazmierski J, Nowakowska K, Łucka A, Antoszczyk A, Oltra-Cucarella J, Werzowa W, Hellevik MM, Skouras S and Bagger K
Virtual reality (VR) has emerged as a promising technology for enhancing the health care of older individuals, particularly in the domains of cognition, physical activity, and social engagement. However, existing VR products and services have limited availability and affordability; hence, there is a need for a scientifically validated and personalized VR service to be used by older adults in their homes, which can improve their overall physical, cognitive, and social well-being.
Aggregation-resistant alpha-synuclein tetramers are reduced in the blood of Parkinson's patients
de Boni L, Wallis A, Hays Watson A, Ruiz-Riquelme A, Leyland LA, Bourinaris T, Hannaway N, Wüllner U, Peters O, Priller J, Falkenburger BH, Wiltfang J, Bähr M, Zerr I, Bürger K, Perneczky R, Teipel S, Löhle M, Hermann W, Schott BH, Brockmann K, Spottke A, Haustein K, Breuer P, Houlden H, Weil RS and Bartels T
Synucleinopathies such as Parkinson's disease (PD) are defined by the accumulation and aggregation of the α-synuclein protein in neurons, glia and other tissues. We have previously shown that destabilization of α-synuclein tetramers is associated with familial PD due to SNCA mutations and demonstrated brain-region specific alterations of α-synuclein multimers in sporadic PD patients following the classical Braak spreading theory. In this study, we assessed relative levels of disordered and higher-ordered multimeric forms of cytosolic α-synuclein in blood from familial PD with G51D mutations and sporadic PD patients. We used an adapted in vitro-cross-linking protocol for human EDTA-whole blood. The relative levels of higher-ordered α-synuclein tetramers were diminished in blood from familial PD and sporadic PD patients compared to controls. Interestingly, the relative amount of α-synuclein tetramers was already decreased in asymptomatic G51D carriers, supporting the hypothesis that α-synuclein multimer destabilization precedes the development of clinical PD. Our data, therefore suggest that measuring α-synuclein tetramers in blood may have potential as a facile biomarker assay for early detection and quantitative tracking of PD progression.
Enhancing patient-clinician collaboration during treatment decision-making: study protocol for a community-engaged, mixed method hybrid type 1 trial of collaborative decision skills training (CDST) for veterans with psychosis
Treichler EBH, McBride LE, Gomez E, Jain J, Seaton S, Yu KE, Oakes D, Perivoliotis D, Girard V, Reznik S, Salyers MP, Thomas ML, Spaulding WD, Granholm EL, Rabin BA and Light GA
Patient participation in treatment decision making is a pillar of recovery-oriented care and is associated with improvements in empowerment and well-being. Although demand for increased involvement in treatment decision-making is high among veterans with serious mental illness, rates of involvement are low. Collaborative decision skills training (CDST) is a recovery-oriented, skills-based intervention designed to support meaningful patient participation in treatment decision making. An open trial among veterans with psychosis supported CDST's feasibility and demonstrated preliminary indications of effectiveness. A randomized control trial (RCT) is needed to test CDST's effectiveness in comparison with an active control and further evaluate implementation feasibility.
Repeatability of image quality in very low-field MRI
Poojar P, Oiye IE, Aggarwal K, Jimeno MM, Vaughan JT and Geethanath S
Very low-field MR has emerged as a promising complementary device to high-field MRI scanners, offering several advantages. One of the key benefits is that very low-field scanners are generally more portable and affordable to purchase and maintain, making them an attractive option for medical facilities looking to reduce costs. Very low-field MRI systems also have lower RF power deposition, making them safer and less likely to cause tissue heating or other safety concerns. They are also simpler to maintain, as they do not require cooling agents such as liquid helium. However, these portable MR scanners are impacted by temperature, lower magnetic field strength, and inhomogeneity, resulting in images with lower signal-to-noise ratio (SNR) and higher geometric distortions. It is essential to investigate and tabulate the variations in these parameters to establish bounds so that subsequent in vivo studies and deployment of these portable systems can be well informed.
Targeting self-care adherence for glycaemic control in multimorbid type 2 diabetes mellitus with depression using bupropion: a protocol for cross-over randomised controlled trial
Shamim MA, Shukla R, Swami MK, Srivastav S, Pradhan A, Yadav SS, Anil A, Saravanan A, Varthya SB, Singh S and Dwivedi P
Diabetes and depression are among the 10 biggest health burdens globally. They often coexist and exhibit a strong bidirectional relationship. Depression leads to decreased adherence to self-care activities. This impacts glycaemic control and worsens type 2 diabetes mellitus (T2D). Both conditions have a synergistic effect and lead to greater complications, hospitalisations, healthcare expenditure and a worse quality of life. There is no consensus on managing people with comorbid T2D and depression. Bupropion is an efficacious antidepressant with many properties suitable for T2D with depression, including a favourable metabolic profile, persistent weight loss and improvement in sexual dysfunction. We will assess the efficacy and safety of add-on bupropion compared with standard care in people with T2D and mild depression. This study can give valuable insights into managing the multimorbidity of T2D and depression. This can help mitigate the health, social and economic burden of both these diseases.
Atomoxetine: toxicological aspects of a new treatment for Attention Deficit Hyperactivity Disorder in Brazil
Morais GCF, Akash S, da Silva ED, de Oliveira CBS, Rodrigues-Neto JF, Fulco UL, Akter S and Oliveira JIN
Atomoxetine is a drug widely used for the treatment of the attention deficit hyperactivity disorder (ADHD) with reduced risk of adverse motor reactions and chemical dependence. However, the pharmacokinetics characteristics as well as the toxicological risk of atomoxetine deserves further investigation to comprehensively analyze the therapeutic and safety aspects of this drug. This study aimed to predict the physicochemical profile and medicinal chemistry characteristics of atomoxetine, alongside its pharmacokinetic properties-namely absorption, distribution, metabolism, and excretion-as well as its toxicology (ADMET) potential through the utilization of web-based in silico tools. This research emphasizes predicted physicochemical, medicinal chemistry, and absorption parameters of atomoxetine that could influence the efficacy and safety of this drug for ADHD treatment. Additionally, atomoxetine also presents noteworthy predicted risks of hepatotoxicity, cardiotoxicity, neurotoxicity, nephrotoxicity, respiratory system toxicity, skin toxicity, and carcinogenicity. These findings underscore the necessity for further assessments of atomoxetine's safety profile, particularly considering different patient populations and durations of drug treatment. The data reported here from in silico predictions suggest that closer monitoring is warranted when atomoxetine is administered to patients with ADHD. Moreover, controlled studies detailing reliable protocols for personalized dosing, considering the multifactorial variability in metabolism efficiency and toxicological potential, would enable a more comprehensive assessment of atomoxetine's safety profile.
Protocol for the development of a vaping cessation intervention for young adult veterans
Doran N, Hurst S, Liu J, El-Shahawy O, Myers M and Krebs P
The use of e-cigarettes ("vaping") by young adults has increased substantially in the past decade. Although health risks of long-term e-cigarette use remain unknown, there is evidence of acute physiological harms. Most young adults who vape report intent to quit, but little is known about effective interventions. This protocol paper reports on the development and design of a pilot trial of a vaping intervention for young military Veterans. Young adult Veterans accessing VA healthcare (n = 20) who vape daily and have been referred for cessation services will be enrolled. To maximize accessibility the intervention will be delivered virtually; participants will be randomized to receive behavioral counseling by telephone or by video telehealth. The intervention was adapted from an existing program targeting young adult cigarette smokers and will include 6 individual counseling sessions delivered over 8 weeks. Assessment visits will occur at baseline, at end-of-treatment, and 4 weeks later. Analyses will evaluate feasibility and acceptability of the intervention overall, and will compare telephone and video telehealth modalities. Longitudinal regression will be used to evaluate changes in vaping behavior and in nicotine dependence over time. This study will provide assessment of a novel intervention adapted for Veterans who vape nicotine. The comparison of two modalities of virtual intervention delivery will increase knowledge and the potential to disseminate across VA and other healthcare systems. Findings from this pilot trial will inform the design of future, larger studies of vaping cessation interventions for younger Veterans.
Treatment of Locally Advanced Rectal Cancer in the Era of Total Neoadjuvant Therapy: A Systematic Review and Network Meta-Analysis
Turri G, Ostuzzi G, Vita G, Barresi V, Scarpa A, Milella M, Mazzarotto R, Ruzzenente A, Barbui C and Pedrazzani C
Treatment of locally advanced rectal cancer (LARC) involves neoadjuvant chemoradiotherapy plus total mesorectal excision and adjuvant chemotherapy. However, total neoadjuvant therapy (TNT) protocols (ie, preoperative chemotherapy in addition to radiotherapy) may allow better adherence and early treatment of distant micrometastases and may increase pathological complete response (pCR) rates.
Dementia in Rare Genetic Neurodevelopmental Disorders: A Systematic Literature Review
Kwetsie H, van Schaijk M, Van Der Lee S, Maes-Festen D, Ten Hoopen LW, van Haelst MM, Coesmans M, Van Den Berg E, De Wit MCY, Pijnenburg Y, Aronica E, Boot E and Van Eeghen AM
Knowledge of young-onset Alzheimer disease in adults with Down syndrome has greatly improved clinical care. However, little is known about dementia in rare genetic neurodevelopmental disorders (RGNDs). In this review, a comprehensive overview is provided of reports on dementia and cognitive/adaptive trajectories in adults with RGNDs.

Prevalence of Opioid Use in Nursing Homes Over the Last Decade: A Systematic Literature Review
Sant AM, Portelli S, Ballard C, Bezzina-Xuereb M, Scerri C and Sultana J
Despite global concerns of an opioid epidemic, there is no systematic literature review on how frequently these drugs are used in nursing home (NH) populations, including those living with dementia. This systematic review aims to describe the prevalence and incidence of opioid use in NHs. A secondary objective is to describe the use of these drugs in a subset of NH residents, namely among persons living with dementia. A systematic literature review was carried out using MEDLINE and Scopus (PROSPERO registration number CRD42021254210). Screening of title and abstract was carried out by 2 persons independently for studies published between January 1, 2011 and May 19, 2021. The main outcomes were annual prevalence, period prevalence, and duration of opioid use. From a total of 178 identified studies, 29 were considered eligible for inclusion. The annual prevalence of any opioid use among all NH residents without any selection criteria ranged from 6.3% to 50% with a median annual prevalence of 22.9% (Q25-Q75: 19.5%-30.2%), based on 17 studies. Five studies measured the annual prevalence in NH residents living with dementia, finding that this ranged from 10% to 39.6%. More evidence is needed quantifying opioid use in NH, especially among persons living with dementia. Given that opioid use in NH is still a problem, implementation of a pain management protocol in NH or nationally would help improve clinical outcomes.
Group-format, peer-facilitated mental health promotion interventions for students in higher education settings: a scoping review protocol
Brooke-Sumner C, Machisa MT, Sikweyiya Y and Mahlangu P
Young people in higher education face various stressors that can make them vulnerable to mental ill-health. Mental health promotion in this group therefore has important potential benefits. Peer-facilitated and group-format interventions may be feasible and sustainable. The scoping review outlined in this protocol aims to map the literature on group-format, peer-facilitated, in-person interventions for mental health promotion for higher education students attending courses on campuses in high and low/middle-income countries.
Supporting ColoREctal Equitable Navigation (SCREEN): a protocol for a stepped-wedge cluster randomized trial for patient navigation in primary care
Rivera Rivera JN, AuBuchon KE, Schubel LC, Starling C, Tran J, Locke M, Grady M, Mete M, Blumenthal HJ, Galarraga JE and Arem H
Black individuals in the United States (US) have a higher incidence of and mortality from colorectal cancer (CRC) compared to other racial groups, and CRC is the second leading cause of death among Hispanic/Latino populations in the US. Patient navigation is an evidence-based approach to narrow inequities in cancer screening among Black and Hispanic/Latino patients. Despite this, limited healthcare systems have implemented patient navigation for screening at scale.
Comparative Metabolomics and Microbiome Analysis of Ethanol versus OMNImet/gene•GUT Fecal Stabilization
Isokääntä H, Pinto da Silva L, Karu N, Kallonen T, Aatsinki AK, Hankemeier T, Schimmel L, Diaz E, Hyötyläinen T, Dorrestein PC, Knight R, Orešič M, Kaddurah-Daouk R, Dickens AM and Lamichhane S
Metabolites from feces provide important insights into the functionality of the gut microbiome. As immediate freezing is not always feasible in gut microbiome studies, there is a need for sampling protocols that provide the stability of the fecal metabolome and microbiome at room temperature (RT). Here, we investigated the stability of various metabolites and the microbiome (16S rRNA) in feces collected in 95% ethanol (EtOH) and commercially available sample collection kits with specific preservatives OMNImet•GUT/OMNIgene•GUT. To simulate field-collection scenarios, the samples were stored at different temperatures at varying durations (24 h + 4 °C, 24 h RT, 36 h RT, 48 h RT, and 7 days RT) and compared to aliquots immediately frozen at -80 °C. We applied several targeted and untargeted metabolomics platforms to measure lipids, polar metabolites, endocannabinoids, short-chain fatty acids (SCFAs), and bile acids (BAs). We found that SCFAs in the nonstabilized samples increased over time, while a stable profile was recorded in sample aliquots stored in 95% EtOH and OMNImet•GUT. When comparing the metabolite levels between aliquots stored at room temperature and at +4 °C, we detected several changes in microbial metabolites, including multiple BAs and SCFAs. Taken together, we found that storing samples at RT and stabilizing them in 95% EtOH yielded metabolomic results comparable to those from flash freezing. We also found that the overall composition of the microbiome did not vary significantly between different storage types. However, notable differences were observed in the α diversity. Altogether, the stability of the metabolome and microbiome in 95% EtOH provided results similar to those of the validated commercial collection kits OMNImet•GUT and OMNIgene•GUT, respectively.
A Scoping Review of the Effect of EEG Neurofeedback on Pain Complaints in Adults with Chronic Pain
Schuurman BB, Lousberg RL, Schreiber JU, van Amelsvoort TAMJ and Vossen CJ
Non-pharmacological treatments such as electroencephalogram (EEG) neurofeedback have become more important in multidisciplinary approaches to treat chronic pain. The aim of this scoping review is to identify the literature on the effects of EEG neurofeedback in reducing pain complaints in adult chronic-pain patients and to elaborate on the neurophysiological rationale for using specific frequency bands as targets for EEG neurofeedback. A pre-registered scoping review was set up and reported following the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) extension for Scoping Reviews (PRISMA-ScR). The data were collected by searching for studies published between 1985 and January 2023 in PubMed, EMBASE, and PsycINFO. Thirty-two studies on various types of chronic pain were included. The intervention was well-tolerated. Approximately half of the studies used a protocol that reinforced alpha or sensorimotor rhythms and suppressed theta or beta activity. However, the underlying neurophysiological rationale behind these specific frequency bands remains unclear. There are indications that neurofeedback in patients with chronic pain probably has short-term analgesic effects; however, the long-term effects are less clear. In order to draw more stable conclusions on the effectiveness of neurofeedback in chronic pain, additional research on the neurophysiological mechanisms of targeted frequency bands is definitely worthwhile. Several recommendations for setting up and evaluating the effect of neurofeedback protocols are suggested.
Validating cognitive screening in young people with first-episode psychosis: The CogScreen protocol
Stainton A, Bryce S, Rattray A, Pert A, Zbukvic I, Fisher E, Anderson D, Bowden SC, Chakma S, Cheng N, Clark S, Crlenjak C, Francey S, Gao C, Gee D, Gelok E, Harris A, Hatfield L, Hopkins L, Jensen C, Morell R, O'Halloran C, Purdon S, Schubert KO, Scully A, Tang H, Thomas A, Thompson A, Uren J, Wood SJ, Zhao W and Allott K
Cognitive impairments are a core feature of first-episode psychosis (FEP) and one of the strongest predictors of long-term psychosocial functioning. Cognition should be assessed and treated as part of routine clinical care for FEP. Cognitive screening offers the opportunity to rapidly identify and triage those in most need of cognitive support. However, there are currently no validated screening measures for young people with FEP. CogScreen is a hybrid effectiveness-implementation study which aims to evaluate the classification accuracy (relative to a neuropsychological assessment as a reference standard), test-retest reliability and acceptability of two cognitive screening tools in young people with FEP.
Effects of participatory organizational interventions on mental health and work performance: A protocol for systematic review and meta-analysis
Iida M, Sakuraya A, Imamura K, Asaoka H, Arima H, Ando E, Inoue A, Inoue R, Iwanaga M, Eguchi H, Otsuka Y, Kobayashi Y, Komase Y, Kuribayashi K, Sasaki N, Tsuno K, Hino A, Watanabe K, Ebara T, Shimazu A, Kawakami N and Tsutsumi A
Participatory organizational interventions to improve psychosocial working conditions are important for a safe and healthy work environment. However, there are few systematic reviews or meta-analyses investigating the effects of these interventions on workers' mental health and work-related outcomes. We apply the protocol for systematic review and meta-analysis to examine the effect of participatory organizational intervention on mental health and work performance.
Association of type 2 diabetes with family history of diabetes, diabetes biomarkers, mental and physical disorders in a Kenyan setting
Ndetei DM, Mutiso V, Musyimi C, Nyamai P, Lloyd C and Sartorius N
This study aimed to determine the degree of family relations and associated socio-demographics characteristics, clinical/physical and mental disorders in type 2 diabetes mellitus in a Kenyan diabetes clinic. This study was part of a large multicentre study whose protocol and results had been published. It took place at the outpatient diabetes clinic at a County Teaching and Referral Hospital in South East Kenya involving 182 participants. We used a socio-demographic questionnaire, the Hamilton Depression (HAM-D) and PHQ-9 rating scales for depression, the MINI International Neuropsychiatric Interview (MINI; V5 or V6) for DSM-5 diagnoses, the WHO-5 Well-being scale and Problem Areas in Diabetes Scale (PAID). We extracted from the notes all physical conditions. We enquired about similar conditions in 1st and 2nd degree relatives. Descriptive, Chi-square test, Fisher's exact test, one way ANOVA, and Multinomial logistic regression analysis were conducted to test achievements of our specific aims. Of the 182 patients who participated in the study, 45.1% (82/182) reported a family history of diabetes. Conditions significantly (p < 0.05) associated with a degree of family history of diabetes were retinopathy, duration of diabetes (years), hypertension, and depressive disorder. On average 11.5% (21/182) scored severe depression (≥ 10) on PHQ-9 and 85.2% (115/182) scored good well-being (≥ 13 points). All DSM-5 psychiatric conditions were found in the 182 patients in varying prevalence regardless of relations. In addition, amongst the 182 patients, the highest prevalence was poor well-being on the WHO quality of life tool. This was followed by post-traumatic disorders (current), suicidality, and psychotic lifetime on DSM-5. The least prevalent on DSM-5 was eating disorders. Some type 2 diabetes mellitus physical disorders and depression have increased incidence in closely related patients. Overall, for all the patients, the prevalence of all DSM-5 diagnoses varied from 0.5 to 9.9%.
A Brief Workplace Training Program to Support Help-Seeking for Mental Ill-Health: Protocol for the Helipad Cluster Randomized Controlled Trial
Batterham PJ, Gulliver A, Heffernan C, Calear AL, Werner-Seidler A, Turner A, Farrer LM, Chatterton ML, Mihalopoulos C and Berk M
Most people with mental health problems do not seek help, with delays of even decades in seeking professional help. Lack of engagement with professional mental health services can lead to poor outcomes and functional impairment. However, few effective interventions have been identified to improve help-seeking in adults, and those that exist are not widely implemented to deliver public health impact. Co-designing interventions with people with lived experience of mental ill-health and other relevant stakeholders is critical to increase the likelihood of uptake and engagement with these programs.
A primer on sampling rates of ambulatory assessments
Seizer L, Schiepek G, Cornelissen G and Löchner J
The use of ambulatory assessments (AAs) as an approach to gather self-reported questionnaires or self-collected biochemical data is constantly increasing to investigate the experiences, states, and behaviors of individuals and their interaction with external situational factors during everyday life. It is often implicitly assumed that data from different sampling protocols can be used interchangeably, despite them assessing processes over different timescales in different intervals and at different occasions, which depending on the variables under study may result in fundamentally different dynamics. There are multiple temporal parameters to consider and while there is an abundance of sampling protocols that are applied regularly, to date, there is only limited empirical background on the influence different approaches may have on the data and findings. In this review, we aim to give an overview of commonly used types of AA in psychology, psychiatry, and biobehavioral research with a breakdown by temporal design parameters. Additionally, we discuss potential advantages and pitfalls associated with the various approaches. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
Remote family education and support program for parents of patients with adolescent and early adulthood eating disorders based on interpersonal psychotherapy: study protocol for a pilot randomized controlled trial
Katsuki F, Watanabe N, Kondo M, Sawada H and Yamada A
In cases of adolescent and early adulthood eating disorders, despite the importance of the patients' relationship with their parents, conflict and confusion frequently occur among them. Interpersonal psychotherapy (IPT) is a present-focused psychotherapy that emphasizes the interpersonal context of symptoms. We developed a remote family education and support program exclusively for parents of patients with eating disorders, based on the principle of IPT. The use of IPT is expected to reduce conflicts in the patient-parent relationship. Consequently, parents will be better able to listen to patients, and patients will be better able to express their thoughts and desires. In this study, we describe the protocol for a randomized controlled trial designed to examine the effectiveness of this program in promoting effective communication in their home based on active listening skills of parents of patients with adolescent and early adulthood eating disorders.
Contingency Management for Dually Diagnosed Inpatients with Psychosis
Docx L, Destoop M and Dom G
Contingency management (CM) is an evidence-based treatment method in substance abuse treatment. However, little is known about its efficacy in dually diagnosed patients with psychosis and in inpatient settings. Therefore, the aim of this study is to investigate the efficacy of CM for dually diagnosed patients with psychosis in an inpatient setting. Furthermore, we investigate the effect of the nature of the reward used (cash vs. prize) on the efficacy of CM. We made use of an 8-week fish-bowl CM intervention by means of a within-subject reversal design with three treatment phases (baseline-intervention-follow-up). Sixty-seven patients were included in this study, of whom thirty-four completed the protocol. The results show no effect of CM on abstinence nor an interaction with clinical or demographic variables. Cash money is as effective as prizes. Future research should further investigate the effect of psychosis and treatment setting on the efficacy of CM, with special attention for Patient Report Experience and Outcome Measures (PREM/PROM).
Use of Ordered Beta Regression Unveils Cognitive Flexibility Index and Longitudinal Cognitive Training Signatures in Normal and Alzheimer's Disease Pathological Aging
Alveal-Mellado D and Giménez-Llort L
Generalized linear mixed models (GLMMs) are a cornerstone data analysis strategy in behavioral research because of their robustness in handling non-normally distributed variables. Recently, their integration with ordered beta regression (OBR), a novel statistical tool for managing percentage data, has opened new avenues for analyzing continuous response data. Here, we applied this combined approach to investigate nuanced differences between the 3xTg-AD model of Alzheimer's disease (AD) and their C57BL/6 non-transgenic (NTg) counterparts with normal aging in a 5-day Morris Water Maze (MWM) test protocol. Our longitudinal study included 22 3xTg-AD mice and 15 NTg mice (both male and female) assessed at 12 and 16 months of age. By identifying and analyzing multiple swimming strategies during three different paradigms (cue, place task, and removal), we uncovered genotypic differences in all paradigms. Thus, the NTg group exhibited a higher percentage of direct search behaviors, while an association between circling episodes and 3xTg-AD animals was found. Furthermore, we also propose a novel metric-the "Cognitive Flexibility Index"-which proved sensitive in detecting sex-related differences. Overall, our integrated GLMMs-OBR approach provides a comprehensive insight into mouse behavior in the MWM test, shedding light on the effects of aging and AD pathology.
Social Determinants of Health and Health Equity in the Treatment and Rehabilitation of Sport-Related Concussion: A Content Analysis of Intervention Research and Call-To-Action

This review was designed to (i) determine the extent to which the clinical science on sport-related concussion treatment and rehabilitation has considered social determinants of health (SDoH) or health equity and (ii) offer recommendations to enhance the incorporation of SDoH and health equity in concussion treatment research and clinical care. The Concussion in Sport Group consensus statement (2023) was informed by two systematic reviews examining prescribed rest or exercise following concussion and targeted interventions to facilitate concussion recovery. We examined 31 studies, including 2,698 participants, from those two reviews. Race (k=6; 19.4%) and ethnicity (k=4; 12.9%) were usually not reported. Four studies examined ethnicity (i.e., Hispanic), exclusively as a demographic category. Five studies (16.1%) examined race as a demographic category. Three studies (9.7%) examined socioeconomic status (SES; measured as household income) as a demographic category/sample descriptor and one study (3.2%) examined SES in depth, by testing whether the treatment and control groups differed by SES. Five studies examined a SDoH domain in a descriptive manner and four studies in an inferential/intentional manner. No study mentioned SDoH, health equity, or disparities by name. Many studies (61.3%) excluded participants based on demographic, sociocultural, or health factors, primarily due to language proficiency. The new consensus statement includes recommendations for concussion treatment and rehabilitation that rely on an evidence base that has not included SDoH or studies addressing health equity. Researchers are encouraged to design treatment and rehabilitation studies that focus specifically on under-represented groups to determine if they have specific and unique treatment and rehabilitation needs, whether certain practical modifications to treatment protocols might be necessary, and whether completion rates and treatment adherence and response are similar.

Exploring early life social and executive function development in infants and risk for autism: a prospective cohort study protocol of NICU graduates and infants at risk for cerebral palsy
Boulton KA, Lee D, Honan I, Phillips NL, Morgan C, Crowle C, Novak I, Badawi N and Guastella AJ
Delays in early social and executive function are predictive of later developmental delays and eventual neurodevelopmental diagnoses. There is limited research examining such markers in the first year of life. High-risk infant groups commonly present with a range of neurodevelopmental challenges, including social and executive function delays, and show higher rates of autism diagnoses later in life. For example, it has been estimated that up to 30% of infants diagnosed with cerebral palsy (CP) will go on to be diagnosed with autism later in life.
Implementation Barriers Encountered During a Universal Suicide Screening Program in Pediatric Emergency Departments
Seag DEM, Cervantes PE, Narcisse I, Wiener E, Tay ET, Knapp K and Horwitz SM
Because understanding barriers to universal suicide risk screening in pediatric emergency departments (PEDs) may improve both identification and management of suicidal behaviors and ideation, this study assessed barriers to a quality improvement initiative examining the use of a novel computerized adaptive test (CAT), the Kiddie-CAT, in 2 PEDs.
Effectiveness of a peer-supported crisis intervention to reduce the proportion of compulsory admissions in acute psychiatric crisis interventions in an outreach and outpatient setting: study protocol for an exploratory cluster randomised trial combined with qualitative methods
Oeltjen LK, Schulz M, Heuer I, Knigge G, Nixdorf R, Briel D, Hamer P, Brannath W, Utschakowski J, Mahlke C and Gerhardus A
Compulsory admissions are associated with feelings of fear, humiliation and powerlessness. The number of compulsory admissions in Germany and other high-income countries has increased in recent years. Peer support has been shown to increase the self-efficacy of individuals with mental health conditions in acute crises and to reduce the use of coercive measures in clinical settings. The objective of this study is to reduce the number of compulsory admissions by involving peer support workers (PSWs) in acute mental health crises in outreach and outpatient settings.
Navigating Community-Based Psychiatry Care of Pediatric Patients in Low-Resource Settings: A Case Report
Regian N, Mittal A, Chammany M, Rai HP and Rommen M
This case report examines the experience of a nine-year-old male with autism spectrum disorder (ASD) who was admitted to his rural community emergency department (ED) for the treatment of aggressive behaviors, agitation, and violence. Despite a high prevalence of such behaviors within the autistic pediatric population, multiple inpatient facilities that offer pediatric psychiatric services refused to transfer his care. Many other commonly used resources and treatment modalities were also not available, resulting in a nine-day ED boarding experience with minimal symptomatic improvement. Pharmacotherapy was utilized, but nationally recommended guidelines were not appropriately followed. Although this case is one of many pediatric patients who received inadequate psychiatric care from their local ED, it is significant in identifying specific areas of improvement within Northeast Louisiana psychiatric healthcare. This case report of a nine-year-old male with autism underlines the hardships faced by patients and their families due to the gaps in our current healthcare infrastructure and emphasizes the importance of protocols and resources for patient populations with higher-than-average wellness needs.

Bieri JS, Ikae C, Souissi SB, Müller TJ, Schlunegger MC and Golz C
There is an urgent need worldwide for qualified health professionals. High attrition rates among health professionals, combined with a predicted rise in life expectancy, further emphasize the need for additional health professionals. Work-related stress is a major concern among health professionals, affecting both the well-being of health professionals and the quality of patient care.
eHealth mindfulness-based music therapy for patients undergoing allogeneic hematopoietic stem cell transplantation: A pilot randomized controlled trial protocol
Fleszar-Pavlovic SE, Esquives BN, Brito AE, Sia AM, Kauffman MA, Lopes M, Moreno PI, Koru-Sengul T, Gong R, Wang T, Wieder ED, Rueda-Lara M, Antoni M, Komanduri K, Lesiuk T and Penedo FJ
Allogeneic stem cell transplantation (allo-SCT) is the preferred therapy for patients with high-risk or relapsed hematologic malignancies, but may be complicated by psychological distress (e.g., depression, anxiety) and symptom burden (e.g., fatigue, pain). Mindfulness-based music therapy (MBMT), a relatively novel integrative medicine intervention that draws from mindfulness and music therapy principles, has shown promise in improving psychosocial outcomes and symptom burden in cancer patients. We outline an eHealth-based MBMT (eMBMT) intervention protocol examining: (1) feasibility, acceptability, and intended effects of eMBMT in improving HRQOL, symptom burden, and clinical markers of disease activity (e.g., infections), and (2) the extent to which eMBMT music therapy component-associated improvements in HRQOL, symptom burden, and disease activity are mediated by improvements in psychosocial and physiological (e.g., systemic inflammation, immune recovery) adaptation.
Mentalising imagery therapy for family dementia caregivers: protocol for a scoping review
Jiang X and Jiang H
Dementia is a growing public health concern, and providing long-term care for individuals affected by this condition is challenging for their family caregivers. While researchers have explored various intervention options to provide psychological support for dementia caregivers, mentalising imagery therapy (MIT) has gained significant recognition as an effective programme. Despite its significance and effectiveness, there is a lack of comprehensive scoping reviews of MIT in dementia caregiving. Thus, conducting such a review can provide valuable insights into the status and outcomes of MIT, identify gaps in existing research and provide recommendations for a more effective clinical practice.

An Immersive Virtual Reality Intervention for Preoperative Anxiety and Distress Among Adults Undergoing Oncological Surgery: Protocol for a 3-Phase Development and Feasibility Trial
El-Gabalawy R, Sommer JL, Hebbard P, Reynolds K, Logan GS, Smith MSD, Mutter TC, Mutch WA, Mota N, Proulx C, Gagnon Shaigetz V, Maples-Keller JL, Arora RC, Perrin D, Benedictson J and Jacobsohn E
Preoperative state anxiety (PSA) is distress and anxiety directly associated with perioperative events. PSA is associated with negative postoperative outcomes such as longer hospital length of stay, increased pain and opioid use, and higher rates of rehospitalization. Psychological prehabilitation, such as education, exposure to hospital environments, and relaxation strategies, has been shown to mitigate PSA; however, there are limited skilled personnel to deliver such interventions in clinical practice. Immersive virtual reality (VR) has the potential for greater accessibility and enhanced integration into an immersive and interactive experience. VR is rarely used in the preoperative setting, but similar forms of stress inoculation training involving exposure to stressful events have improved psychological preparation in contexts such as military deployment.

Efficacy and safety of acupuncture therapy for Parkinson's disease with neuropsychiatric symptoms: protocol for a systematic review and meta-analysis
Tan W, Liu Q, Cen M, Leong II, Pan Z, Liao M and Zhuang L
Neuropsychiatric symptoms (NPS) are common non-motor symptoms among patients with Parkinson's disease (PD) and significantly impact their overall quality of life detrimentally. Several studies have reported the clinical effect of acupuncture therapy in treating NPS in PD. Therefore, the objective of this systematic review is to evaluate the potential inclusion of acupuncture therapy as an integral component of complementary treatment for PD with NPS.
Care challenges and silver linings in HIV and behavioral health service delivery for individuals living with HIV and severe mental illness during the COVID-19 pandemic: a qualitative study
Dahiya P, Riano NS, Dilley JW, Olfson M, Cournos F, Mangurian C and Arnold EA
There has been a longstanding effort to integrate behavioral health and HIV care for people with comorbid HIV and behavioral health needs, including those with severe mental illness (SMI). As this population frequents both behavioral health and HIV care settings, they were likely to experience new obstacles to the quality and availability of care during the COVID-19 pandemic. This study aims to describe how clinics for HIV services or behavioral healthcare-as well as co-located sites providing both-sought to rapidly shift protocols to maintain a standard of patient care for people with comorbid HIV and SMI while adapting to the unprecedented circumstances of the pandemic.
Internet-delivered cognitive-behaviour therapy for anxiety related to asthma: study protocol for a randomised controlled trial
Bonnert M, Nash S, Andersson EM, Bergström SE, Janson C and Almqvist C
There is an established association between asthma and anxiety. The overlap between asthma symptoms and symptoms of anxiety may cause individuals to overestimate their asthma severity and restrict their daily activities leading to a low quality of life. There is currently weak evidence for treatments targeting anxiety related to asthma, but cognitive-behavioural therapy (CBT) has shown some promising but mixed results. The current randomised controlled trial will investigate if exposure-based internet-delivered CBT (Internet-CBT) is more effective than treatment as usual+medical education (TAU+ME) to relieve symptoms of anxiety and asthma control.
Tripod transcranial alternating current stimulation at 5-Hz to alleviate anxiety symptoms: A preliminary report
Lee TW, Li CR and Tramontano G
One of the most common applications of transcranial electrical stimulation (tES) at low current intensity is to induce a relaxed state or reduce anxiety. With technical advancement, different waveforms, montages, and parameters can be incorporated into the treatment regimen. We developed a novel protocol to treat individuals with anxiety disorders by transcranial alternating current stimulation (tACS).
Effectiveness of combining prevention psychological interventions with interventions that address the social determinants of mental health in low and middle-income countries: protocol of a systematic review and meta-analysis
Prina E, Bano B, Singh R, Albanese E, Trujillo D, Dedios Sanguineti MC, Sorsdahl K, Luitel NP, Garman EC, Purgato M, Barbui C, Jordans MJD and Lund C
Common mental health conditions (CMHCs), including depression, anxiety and post-traumatic stress disorder (PTSD), are highly prevalent in low and middle-income countries (LMICs). Preventive strategies combining psychological interventions with interventions addressing the social determinants of mental health may represent a key strategy for effectively preventing CMHCs. However, no systematic reviews have evaluated the effectiveness of these combined intervention strategies for preventing CMHCs.
Efficacy and safety of peri-partum Esketamine for prevention of post-partum depression in women undergoing caesarian section: A meta-analysis and systematic review of randomized controlled trials
Nayyer MA, Khan SM, Umer M, Imran H, Khalid S, Murtaza H, Sarfraz A, Atiq N, Rasool H and Fatima M
Postpartum depression (PPD) is a psychiatric condition affecting women post-childbirth. Medication combined with psychotherapy, is the current protocol for its treatment. A meta-analysis was conducted using RevMan 5.4 to explore the efficacy and safety of peri-partum administration of esketamine for preventing PPD. After searching several databases to retrieve the relevant RCTs, seven were included in this analysis, with dichotomous data presented as risk ratio and continuous data as mean difference. The study found a lower incidence of PPD in the esketamine group compared to the control group (RR= 0.37), with significant difference in EPDS scores between the two groups (MD= -1.23) in the first week postpartum. The esketamine group reported a lower prevalence of PPD 4-6 weeks postpartum (RR= 0.48), and no significant difference in EPDS scores after 4 weeks postpartum (MD = -0.10). The esketamine group had a significantly higher incidence of hallucination (RR= 13.85). Other adverse effects, such as dizziness (RR= 4.09), nausea (RR= 0.88), vomiting (RR=0.74), headache (RR=1.52), nightmares (RR=1.22), pruritus (RR=0.29), and drowsiness (RR=1.57) did not show significant differences between the two groups. The study found that esketamine, with manageable side effects, reduces the prevalence of post-partum depression (PPD) after one week as well as after four to six weeks. However, the findings are limited by the limited number of available RCTs, and future research should determine the ideal dosage, the most effective method of administration and the long-term safety profile of esketamine so that it may be considered as an adjunct therapy or a potential sole treatment option.
A Mind-Body Intervention to Improve Physical Activity for Patients with Chronic Hip-Related Pain: Protocol for a Mixed Methods Study
Jochimsen KN, Archer KR, Pollini RA, Parker RA, Enkhtsetseg N, Jacobs CA and Vranceanu AM
Pain and dysfunction persist for most patients following hip-related pain treatment. Additionally, individuals with hip-related pain are typically less physically active than individuals without hip pain, despite evidence that regular physical activity reduces chronic musculoskeletal pain. Poor psychological health is common in patients with hip-related pain and further reinforces low physical activity. Mind-body interventions can improve psychological health and activity levels but have yet to be integrated to provide comprehensive, psychologically informed care for patients with hip-related pain. Thus, we are using the NCCIH intervention development framework to develop Helping Improve PSychological Health (HIPS), a novel, multimodal mind-body intervention to improve physical activity for individuals with hip-related pain and poor psychological health.

The paper appraises the extant literature on mandatory clozapine haematological monitoring.
Mindfulness in Pregnancy and Postpartum: Protocol of a Pilot Randomized Trial of Virtually Delivered Mindfulness-Based Cognitive Therapy to Promote Well-Being during the Perinatal Period
Donofry SD, Winograd D, Kothari D, Call CC, Magee KE, Jouppi RJ, Conlon RPK and Levine MD
During the period from pregnancy through the first year postpartum, vulnerable individuals are at elevated risk for the onset or worsening of psychological distress, and accessible (e.g., virtually delivered) mental health interventions are needed. Research suggests that Mindfulness-Based Cognitive Therapy (MBCT) can effectively mitigate psychological distress, although few studies have evaluated MBCT in the perinatal period, and samples have been clinically homogenous. Thus, we have designed and are conducting a pilot trial of virtually delivered MBCT with pregnant individuals experiencing a range of psychological symptoms to assess its feasibility and preliminarily explore its effectiveness. Here, we present the study protocol.

PolyI:C Maternal Immune Activation on E9.5 Causes the Deregulation of Microglia and the Complement System in Mice, Leading to Decreased Synaptic Spine Density
Yan S, Wang L, Samsom JN, Ujic D and Liu F
Maternal immune activation (MIA) is a risk factor for multiple neurodevelopmental disorders; however, animal models developed to explore MIA mechanisms are sensitive to experimental factors, which has led to complexity in previous reports of the MIA phenotype. We sought to characterize an MIA protocol throughout development to understand how prenatal immune insult alters the trajectory of important neurodevelopmental processes, including the microglial regulation of synaptic spines and complement signaling. We used polyinosinic:polycytidylic acid (polyI:C) to induce MIA on gestational day 9.5 in CD-1 mice, and measured their synaptic spine density, microglial synaptic pruning, and complement protein expression. We found reduced dendritic spine density in the somatosensory cortex starting at 3-weeks-of-age with requisite increases in microglial synaptic pruning and phagocytosis, suggesting spine density loss was caused by increased microglial synaptic pruning. Additionally, we showed dysregulation in complement protein expression persisting into adulthood. Our findings highlight disruptions in the prenatal environment leading to alterations in multiple dynamic processes through to postnatal development. This could potentially suggest developmental time points during which synaptic processes could be measured as risk factors or targeted with therapeutics for neurodevelopmental disorders.
Characterising illness stages and recovery trajectories of eating disorders in young people via remote measurement technology (STORY): a multi-centre prospective cohort study protocol
Kuehne C, Phillips MD, Moody S, Bryson C, Campbell IC, Conde P, Cummins N, Desrivières S, Dineley J, Dobson R, Douglas D, Folarin A, Gallop L, Hemmings A, İnce B, Mason L, Rashid Z, Bromell A, Sims C, Allen K, Bailie C, Bains P, Basher M, Battisti F, Baudinet J, Bristow K, Dawson N, Dodd L, Frater V, Freudenthal R, Gripton B, Kan C, Khor JWT, Kotze N, Laverack S, Martin L, Maxwell S, McDonald S, McKnight D, McKay R, Merrin J, Nash M, Nicholls D, Palmer S, Pearce S, Roberts C, Serpell L, Severs E, Simic M, Staton A, Westaway S, Sharpe H, Schmidt U, , Bartel H, French T, Kelly J, Micali N, Raman S, Treasure J, Malik U, Rabelo-da-Ponte D, Stephens F, Opitz T, Trompeter N, Wilkins J, Parnell T, Abbas R, Bromell A, Davis G, Eadie C, Gracie L, Heslop B, McKenzie K, Odubanjo E, Sims C, Street T, Tavares-Semedo A, Wilkinson E and Zocek L
Eating disorders (EDs) are serious, often chronic, conditions associated with pronounced morbidity, mortality, and dysfunction increasingly affecting young people worldwide. Illness progression, stages and recovery trajectories of EDs are still poorly characterised. The STORY study dynamically and longitudinally assesses young people with different EDs (restricting; bingeing/bulimic presentations) and illness durations (earlier; later stages) compared to healthy controls. Remote measurement technology (RMT) with active and passive sensing is used to advance understanding of the heterogeneity of earlier and more progressed clinical presentations and predictors of recovery or relapse.
Sex differences in electrolyte abnormalities indicating refeeding syndrome risk among hospitalized adolescents and young adults with eating disorders
Nagata JM, Nguyen A, Vargas R, Downey AE, Chaphekar AV, Ganson KT, Buckelew SM and Garber AK
Refeeding syndrome is the gravest possible medical complication in malnourished patients undergoing refeeding in the hospital. We previously reported that males with malnutrition secondary to eating disorders required more calories and had longer hospital stays than females; however, sex differences in electrolyte abnormalities indicating refeeding syndrome risk remain unknown. The objective of this study was to assess differences in electrolyte abnormalities indicating refeeding syndrome risk among male and female adolescents and young adults with eating disorders hospitalized for medical instability.
Comparative Effectiveness of Different Exercises for Reducing Pain Intensity in Primary Dysmenorrhea: A Systematic Review and Network Meta-analysis of Randomized Controlled Trials
Tsai IC, Hsu CW, Chang CH, Lei WT, Tseng PT and Chang KV
Studies have demonstrated that exercise can mitigate the intensity of menstrual pain in primary dysmenorrhea, but the most effective type of exercise remains unclear. The objective of this systematic review and network meta-analysis was to evaluate the effectiveness of different exercise regimens in reducing pain associated with primary dysmenorrhoea.
The changing landscape of electrical stimulation language mapping with subdural electrodes and stereoelectroencephalography for pediatric epilepsy: A literature review and commentary
Reecher HM, Bearden DJ, Koop JI, Berl MM, Patrick KE and Ailion AS
Electrical stimulation mapping (ESM) is used to locate the brain areas supporting language directly within the human cortex to minimize the risk of functional decline following epilepsy surgery. ESM is completed by utilizing subdural grid or depth electrodes (stereo-electroencephalography [sEEG]) in combination with behavioral evaluation of language. Despite technological advances, there is no standardized method of assessing language during pediatric ESM. To identify current clinical practices for pediatric ESM of language, we surveyed neuropsychologists in the Pediatric Epilepsy Research Consortium. Results indicated that sEEG is used for functional mapping at >80% of participating epilepsy surgery centers (n = 13/16) in the United States. However, >65% of sites did not report a standardized protocol to map language. Survey results indicated a clear need for practice recommendations regarding ESM of language. We then utilized PubMed/Medline and PsychInfo to identify 42 articles that reported on ESM of language, of which 18 met inclusion criteria, which included use of ESM/signal recording to localize language regions in children (<21 years) and a detailed account of the procedure and language measures used, and region-specific language localization outcomes. Articles were grouped based on the language domain assessed, language measures used, and the brain regions involved. Our review revealed the need for evidence-based clinical guidelines for pediatric language paradigms during ESM and a standardized language mapping protocol as well as standardized reporting of brain regions in research. Relevant limitations and future directions are discussed with a focus on considerations for pediatric language mapping.
Effects and safety of transcranial direct current stimulation on multiple health outcomes: an umbrella review of randomized clinical trials
Kang J, Lee H, Yu S, Lee M, Kim HJ, Kwon R, Kim S, Fond G, Boyer L, Rahmati M, Koyanagi A, Smith L, Nehs CJ, Kim MS, Sánchez GFL, Dragioti E, Kim T and Yon DK
Transcranial direct current stimulation (tDCS), which delivers a direct current to the brain, emerged as a non-invasive potential therapeutic in treating a range of neurological and neuropsychiatric disorders. However, a comprehensive quantitative evidence synthesis on the effects of tDCS on a broad range of mental illnesses is lacking. Here, we systematically assess the certainty of the effects and safety of tDCS on several health outcomes using an umbrella review of randomized controlled trials (RCTs). The methodological quality of each included original meta-analysis was assessed by the A Measurement Tool for Assessing Systematic Reviews 2 (AMSTAR2), and the certainty of the evidence for each effect was evaluated with Grading of Recommendations, Assessment, Development, and Evaluation (GRADE). We followed an a priori protocol (PROSPERO CRD42023458700). We identified 15 meta-analyses of RCTs (AMSTAR 2; high 3, moderate 3, and low 9) that included 282 original articles, covering 22 unique health endpoints across 22 countries and six continents. From meta-analyses of RCTs supported by very low to high certainty of evidence, it was found that tDCS improved symptoms related to post-stroke, including post-stroke depression scale score (equivalent standardized mean difference [eSMD], 1.61 [95% confidence level, 0.72-2.50]; GRADE=moderate), activities of daily living independence (7.04 [3.41-10.67]; GRADE=high), motor recovery of upper and lower extremity (upper extremity: 0.15 [0.06-0.24], GRADE=high; lower extremity: 0.10 [0.03-0.16], GRADE=high), swallowing performance (GRADE=low), and spasticity (GRADE=moderate). In addition, tDCS had treatment effects on symptoms of several neurological and neuropsychiatric disorders, including obsessive-compulsive disorder (0.81 [0.44-1.18]; GRADE=high), pain in fibromyalgia (GRADE=low), disease of consciousness (GRADE=low), insight score (GRADE=moderate) and working memory (0.34 [0.01-0.67]; GRADE=high) in schizophrenia, migraine-related pain (-1.52 [-2.91 to -0.13]; GRADE=high), attention-deficit/hyperactivity disorder (reduction in overall symptom severity: 0.24 [0.04-0.45], GRADE=low; reduction in inattention: 0.56 [0.02-1.11], GRADE=low; reduction in impulsivity: 0.28 [0.04-0.51], GRADE=low), depression (GRADE=low), cerebellar ataxia (GRADE=low), and pain (GRADE=very low). Importantly, tDCS induced an increased number of reported cases of treatment-emergent mania or hypomania (0.88 [0.62-1.13]; GRADE=moderate). We found varied levels of evidence for the effects of tDCS with multiple neurological and neuropsychiatric conditions, from very low to high certainty of evidence. tDCS was effective for people with stroke, obsessive-compulsive disorder, fibromyalgia, disease of consciousness, schizophrenia, migraine, attention-deficit/hyperactivity disorder, depression, cerebellar ataxia, and pain. Therefore, these findings suggest the benefit of tDCS for several neurological and neuropsychiatric disorders; however, further studies are needed to understand the underlying mechanism and optimize its therapeutic potential.
Process evaluation of a Structured E-parenting Support (STEPS) in the OPTIMA randomised controlled trial: a protocol
Hedstrom E, Kostyrka-Allchorne K, French B, Glazebrook C, Hall CL, Kovshoff H, Lean N and Sonuga-Barke E
(STEPS) is a digital application (app) designed to help parents manage behaviour of their children who are referred to mental health services and are waiting for an assessment or treatment. STEPS is currently being evaluated in the Online Parent Training for the Initial Management of Attention-Deficit/Hyperactivity Disorder randomised controlled trial. Alongside the examination of STEPS' clinical and cost-effectiveness, we are conducting a process evaluation to better understand the contextual factors that may influence study outcomes. The purpose of this protocol is to describe the aims, objectives and methodology of the process evaluation prior to it taking place to add to the fidelity and rigour of the trial process and outcomes. Our goal is to adapt STEPS to optimise its benefits in future applications.
The neglected association between schizophrenia and bone fragility: a systematic review and meta-analyses
Azimi Manavi B, Corney KB, Mohebbi M, Quirk SE, Stuart AL, Pasco JA, Hodge JM, Berk M and Williams LJ
Schizophrenia is associated with increased risk of medical comorbidity, possibly including osteoporosis, which is a public health concern due to its significant social and health consequences. In this systematic review and meta-analysis, we aimed to determine whether schizophrenia is associated with bone fragility. The protocol for this review has been registered with PROSPERO (CRD42020171959). The research question and inclusion/exclusion criteria were developed and presented according to the PECO (Population, Exposure, Comparison, Outcome) framework. Schizophrenia was identified from medical records, DSM-IV/5 or the ICD. The outcomes for this review were bone fragility [i.e., bone mineral density (BMD), fracture, bone turnover markers, bone quality]. A search strategy was developed and implemented for the electronic databases. A narrative synthesis was undertaken for all included studies; the results from eligible studies reporting on BMD and fracture were pooled using a random effects model to complete a meta-analysis. The conduct of the review and reporting of results adhered to PRISMA guidelines. Our search yielded 3103 studies, of which 29 met the predetermined eligibility criteria. Thirty-seven reports from 29 studies constituted 17 studies investigating BMD, eight investigating fracture, three investigating bone quality and nine investigating bone turnover markers. The meta-analyses revealed that people with schizophrenia had lower BMD at the lumbar spine [standardised mean difference (SMD) -0.74, 95% CI -1.27, -0.20; Z = -2.71, p = 0.01] and at the femoral neck (SMD -0.78, 95% CI -1.03, -0.53; Z = -6.18, p ≤ 0.001). Also observed was a higher risk of fracture (OR 1.43, 95% CI 1.27, 1.61; Z = 5.88, p ≤ 0.001). Following adjustment for publication bias, the association between schizophrenia and femoral neck BMD (SMD -0.63, 95% CI -0.97, -0.29) and fracture (OR 1.32, 95% CI 1.28, 1.35) remained. Significantly increased risk of bone fragility was observed in people with schizophrenia. This association was independent of sex, participant number, methodological quality and year of publication.
Variation in care for inpatients with avoidant restrictive food intake disorder leads to development of a novel inpatient clinical pathway to standardize care
Bern EM, Milliren CE, Tsang KK, Mancini LA, Carmody JK, Gearhart MG, Eldredge O, Samsel C, Crowley M and Richmond TK
There is limited evidence to guide management of patients with avoidant restrictive food intake disorder (ARFID) admitted for medical stabilization. We describe variations in inpatient care which led to the development of a multidisciplinary inpatient clinical pathway (ICP) to provide standardized management and examine differences after the ICP was implemented.
Clinical dimensions of people with co-occurring obsessive-compulsive and related disorders and multiple sclerosis: a scoping review protocol
Freedman DE, Sawicka KM, Oh J, Main E, Campbell KA and Feinstein A
Multiple sclerosis (MS) is an immune-mediated demyelinating disease with a significant burden of neuropsychiatric sequelae. These symptoms, including depression and anxiety, are predictors of morbidity and mortality in people with MS. Despite a high prevalence of obsessive-compulsive disorder in MS, potentially shared pathophysiological mechanisms and overlap in possible treatments, no review has specifically examined the clinical dimensions of people with obsessive-compulsive and related disorders (OCRD) and MS. In this scoping review, we aim to map the available knowledge on the clinical dimensions of people with co-occurring OCRD and MS. Understanding the characteristics of this population in greater detail will inform more patient-centred care and create a framework for future studies.
The Impact of Microbiome Interventions on the Progression and Severity of Inflammatory Bowel Disease: A Systematic Review
Kasapoglu M, Yadavalli R, Nawaz S, Althwanay A, AlEdani EM, Kaur H and Butt S
Inflammatory bowel disease (IBD), comprising Crohn's disease (CD) and ulcerative colitis (UC), is characterized by chronic intestinal inflammation. The dysbiotic gut microbiome likely contributes to IBD pathogenesis. Microbiome-directed therapies such as fecal microbiota transplantation (FMT), probiotics, and synbiotics may help induce and maintain remission. This systematic review aimed to determine the efficacy of microbiome interventions compared to standard therapy or placebo for IBD treatment. PubMed, EMBASE, Cochrane CENTRAL, and Web of Science were searched for randomized controlled trials on microbiome interventions in IBD from inception to October 2023. The risk of bias was assessed using Cochrane tools. Outcomes included disease activity, endoscopy, histology, quality of life, and adverse events. A total of 18 randomized controlled trials were included. Three trials found intensive (i.e., high frequency of administration and/or large volumes of fecal material) multi-donor FMT superior to autologous FMT or glucocorticoids for UC remission induction. Seven placebo-controlled trials demonstrated higher remission rates with FMT, especially intensive protocols, versus control for mild-to-moderate UC. However, a single FMT did not prevent relapses. Seven probiotic trials showed the potential to improve UC activity and maintain remission. One synbiotic trial reported reduced inflammation and symptoms versus placebo. Serious adverse events were rare. Small sample sizes and protocol heterogeneity limited the conclusions. Current evidence indicates the potential benefits of microbiome interventions, particularly intensive multi-donor FMT, for inducing and maintaining remission in UC. Probiotics may also improve outcomes. Adequately powered trials using standardized protocols are still needed to firmly establish efficacy and safety. Microbiome-directed therapies represent a promising approach for improving IBD outcomes.
Propofol enhancement of slow wave sleep to target the nexus of geriatric depression and cognitive dysfunction: protocol for a phase I open label trial
Rios RL, Green M, Smith SK, Kafashan M, Ching S, Farber NB, Lin N, Lucey BP, Reynolds CF, Lenze EJ, Palanca BJA and
Late-life treatment-resistant depression (LL-TRD) is common and increases risk for accelerated ageing and cognitive decline. Impaired sleep is common in LL-TRD and is a risk factor for cognitive decline. Slow wave sleep (SWS) has been implicated in key processes including synaptic plasticity and memory. A deficiency in SWS may be a core component of depression pathophysiology. The anaesthetic propofol can induce electroencephalographic (EEG) slow waves that resemble SWS. Propofol may enhance SWS and oral antidepressant therapy, but relationships are unclear. We hypothesise that propofol infusions will enhance SWS and improve depression in older adults with LL-TRD. This hypothesis has been supported by a recent small case series.
Network-targeted transcranial direct current stimulation of the hypothalamus appetite-control network: a feasibility study
Ester-Nacke T, Berti K, Veit R, Dannecker C, Salvador R, Ruffini G, Heni M, Birkenfeld AL, Plewnia C, Preissl H and Kullmann S
The hypothalamus is the key regulator for energy homeostasis and is functionally connected to striatal and cortical regions vital for the inhibitory control of appetite. Hence, the ability to non-invasively modulate the hypothalamus network could open new ways for the treatment of metabolic diseases. Here, we tested a novel method for network-targeted transcranial direct current stimulation (net-tDCS) to influence the excitability of brain regions involved in the control of appetite. Based on the resting-state functional connectivity map of the hypothalamus, a 12-channel net-tDCS protocol was generated (Neuroelectrics Starstim system), which included anodal, cathodal and sham stimulation. Ten participants with overweight or obesity were enrolled in a sham-controlled, crossover study. During stimulation or sham control, participants completed a stop-signal task to measure inhibitory control. Overall, stimulation was well tolerated. Anodal net-tDCS resulted in faster stop signal reaction time (SSRT) compared to sham (p = 0.039) and cathodal net-tDCS (p = 0.042). Baseline functional connectivity of the target network correlated with SSRT after anodal compared to sham stimulation (p = 0.016). These preliminary data indicate that modulating hypothalamus functional network connectivity via net-tDCS may result in improved inhibitory control. Further studies need to evaluate the effects on eating behavior and metabolism.
Influence of paternal preconception health on pregnancy, intrapartum, postpartum and early childhood outcomes: protocol for a parallel scoping review
Dennis CL, Abbass-Dick J, Birken C, Dennis-Grantham A, Goyal D, Singla D, Letourneau N, McQueen K, Shorey S and Dol J
Preconception care is the provision of behavioural, social or biomedical interventions to women and couples prior to conception. To date, preconception research has primarily focused on maternal health, despite the male partner's contribution before birth to both short-term and long-term child outcomes. The objectives of the reviews are: (1) to identify, consolidate and analyse the literature on paternal preconception health on pregnancy and intrapartum outcomes, and (2) to identify, consolidate and analyse the literature on paternal preconception health on postpartum and early childhood outcomes.

A randomized controlled trial to compare the effects of time-restricted eating versus Mediterranean diet on symptoms and quality of life in bipolar disorder
Johnson SL, Murray G, Kriegsfeld LJ, Manoogian ENC, Mason L, Allen JD, Berk M, Panda S, Rajgopal NA, Gibson JC, Joyner KJ, Villanueva R and Michalak EE
The primary objective of this randomized controlled trial (RCT) is to establish the effectiveness of time-restricted eating (TRE) compared with the Mediterranean diet for people with bipolar disorder (BD) who have symptoms of sleep disorders or circadian rhythm sleep-wake disruption. This work builds on the growing evidence that TRE has benefits for improving circadian rhythms. TRE and Mediterranean diet guidance will be offered remotely using self-help materials and an app, with coaching support.
Information-based TMS to mid-lateral prefrontal cortex disrupts action goals during emotional processing
Lapate RC, Heckner MK, Phan AT, Tambini A and D'Esposito M
The ability to respond to emotional events in a context-sensitive and goal-oriented manner is essential for adaptive functioning. In models of behavioral and emotion regulation, the lateral prefrontal cortex (LPFC) is postulated to maintain goal-relevant representations that promote cognitive control, an idea rarely tested with causal inference. Here, we altered mid-LPFC function in healthy individuals using a putatively inhibitory brain stimulation protocol (continuous theta burst; cTBS), followed by fMRI scanning. Participants performed the Affective Go/No-Go task, which requires goal-oriented action during affective processing. We targeted mid-LPFC (vs. a Control site) based on the individualized location of action-goal representations observed during the task. cTBS to mid-LPFC reduced action-goal representations in mid-LPFC and impaired goal-oriented action, particularly during processing of negative emotional cues. During negative-cue processing, cTBS to mid-LPFC reduced functional coupling between mid-LPFC and nodes of the default mode network, including frontopolar cortex-a region thought to modulate LPFC control signals according to internal states. Collectively, these results indicate that mid-LPFC goal-relevant representations play a causal role in governing context-sensitive cognitive control during emotional processing.
Success rates of intensive aphasia therapy: real-world data from 448 patients between 2003 and 2020
Peitz D, Schumann-Werner B, Hussmann K, Pinho J, Chen H, Binkofski F, Huber W, Willmes K, Heim S, Schulz JB, Fimm B and Werner CJ
Aphasia is a devastating consequence after stroke, affecting millions of patients each year. Studies have shown that intensive speech and language therapy (SLT) is effective in the chronic phase of aphasia. Leveraging a large single-center cohort of persons with aphasia (PWA) including patients also in the subacute phase, we assessed treatment effects of intensive aphasia therapy in a real-world setting.
Protocol for process evaluation of ARTEMIS cluster randomised controlled trial: an intervention for management of depression and suicide among adolescents living in slums in India
Mukherjee A, Yatirajula SK, Kallakuri S, Paslawar S, Lempp H, Raman U, Kumar A, Essue BM, Sagar R, Singh R, Peiris D, Norton R, Thornicroft G and Maulik PK
There are around 250 million adolescents (10-19 years) in India. The prevalence of mental health-related morbidity among adolescents in India is approximately 7.3%. Vulnerable subpopulations among adolescents such as those living in slum communities are particularly at risk due to poor living conditions, financial difficulty and limited access to support services. Adolescents' Resilience and Treatment nEeds for Mental Health in Indian Slums (ARTEMIS) is a cluster randomised controlled trial of an intervention that intends to improve the mental health of adolescents living in slum communities in India. The aim of this paper is to describe the process evaluation protocol for ARTEMIS trial. The process evaluation will help to explain the intervention outcomes and understand how and why the intervention worked or did not work. It will identify contextual factors, intervention barriers and facilitators and the adaptations required for optimising implementation.
Medical students' attitudes towards well-being and welfare: a systematic review protocol
Mazzoleni A, Garg S, Bhatia S and Kumar NS
Medical education poses serious stressors on medical students, as they report overall higher rates of psychiatric comorbidities compared with students enrolled in other university-level courses. The high rates of poor well-being reported should be considered a concern, as students represent the future workforce of healthcare professionals. Although there has been an increased interest towards well-being and burn-out in medical students, there is still much to be elucidated. Indeed, there is an overall lack of understanding of which attitudes medical students have towards well-being and welfare, something that could be used to develop targeted practice to improve medics' quality of life and reduce overall burn-out.This review will aim at evaluating and reporting the current research available on medical students' attitudes towards well-being and welfare. We will take into account which countries have published data on the topic, and we will analyse papers written during the COVID-19 period separately, giving this particular time frame a separate outlook.
Morning light treatment for inflammatory bowel disease: a clinical trial
Cohen-Mekelburg S, Goldstein CA, Rizvydeen M, Fayyaz Z, Patel PJ, Berinstein JA, Bishu S, Cushing-Damm KC, Kim HM and Burgess HJ
Inflammatory bowel disease (IBD) affects over 3 million Americans and has a relapsing and remitting course with up to 30% of patients experiencing exacerbations each year despite the availability of immune targeted therapies. An urgent need exists to develop adjunctive treatment approaches to better manage IBD symptoms and disease activity. Circadian disruption is associated with increased disease activity and may be an important modifiable treatment target for IBD. Morning light treatment, which advances and stabilizes circadian timing, may have the potential to improve IBD symptoms and disease activity, but no studies have explored these potential therapeutic benefits in IBD. Therefore, in this study, we aim to test the effectiveness of morning light treatment for patients with IBD.
START NOW WebApp-promoting emotion regulation and resilience in residential youth care and correctional institutions: study protocol for a cluster randomized controlled trial
Kersten L, Alfano J, Erlanger TE, Helfenstein F, Lanz L, Weiss S, Chilla C, von Planta B, Kapoor M, Borel N, Rocco T, Papageorgiou A, De Brito CF, Bajrami A, Savary V, Mayor M, Hurschler J, Traut A, Brunner D, Vriends N and Stadler C
Adolescents and young adults in residential care and correctional institutions face various challenges, leading to negative life outcomes. Implementation barriers within these institutions, such as limited financial and spatial resources, pose significant hurdles to providing necessary support. Web-based approaches address these challenges by offering cost-effective, accessible solutions. This study aims to assess the efficacy of a newly developed web-based version of the existing evidence-based START NOW skills training in fostering emotion regulation and resilience among institutionalized adolescents and young adults. We present the study protocol (Version 5, August 2023) of the trial titled "Implementation of an e-version of the skills training START NOW for promoting emotion regulation and resilience in residential youth care and correctional institutions".

A Randomized Controlled Trial Comparing Efficacy and Safety of Antidepressant Monotherapy
Santi NS, Biswal SB, Naik BN, Sahoo JP and Rath B
The majority of mainstream antidepressants lack the promise of complete amelioration of symptoms. Other pitfalls include the latency period and side effects. These issues prompted investigations concerning the various roles of serotonin (5-HT) neurotransmissions in the etiology of depression. In this study, each study participant received vilazodone, vortioxetine, and escitalopram monotherapy for major depressive disorder (MDD) for 16 weeks. After that, the subject's scores on the Hamilton Depression Rating Scale (HDRS)-17 item version and the Montgomery Åsberg Depression Rating Scale (MADRS) were evaluated. In the study population, we kept track of the incidence of adverse events.
Study protocol for measuring stigmatization in persistent tic disorders: development and validation of the Tourette discrimination-stigmatization scale
Martindale JM, Ringheanu VM, Pring KA, Norona S, Wiseman K, Strowd RE, Chapman L, Rigdon J, Rapp SR, Storch EA, Ip E and Mink JW
Persistent Tic Disorders such as Tourette Syndrome are common neurodevelopmental disorders that are highly stigmatized. Many individuals with Persistent Tic Disorders experience peer rejection, loneliness, and self-stigma. Experiencing stigmatization during childhood can influence the persistence of moderate-to-severe tics later in life. Additionally, these factors have been associated with increased suicidal ideation, suicide attempts, and psychiatric symptom severity. There is a need for interventions to reduce stigma and stigmatization in Persistent Tic Disorders. Before developing cost-effective interventions to mitigate stigma's profound downstream health impacts, a reliable measure of stigmatization must be created. The overarching goal of this research is to develop and validate the Tourette Discrimination-Stigmatization (TD-STIGMA) Scale.
Bringing together multimodal and multilevel approaches to study the emergence of social bonds between children and improve social AI
Bonnaire J, Dumas G and Cassell J
This protocol paper outlines an innovative multimodal and multilevel approach to studying the emergence and evolution of how children build social bonds with their peers, and its potential application to improving social artificial intelligence (AI). We detail a unique hyperscanning experimental framework utilizing functional near-infrared spectroscopy (fNIRS) to observe inter-brain synchrony in child dyads during collaborative tasks and social interactions. Our proposed longitudinal study spans middle childhood, aiming to capture the dynamic development of social connections and cognitive engagement in naturalistic settings. To do so we bring together four kinds of data: the multimodal conversational behaviors that dyads of children engage in, evidence of their state of interpersonal rapport, collaborative performance on educational tasks, and inter-brain synchrony. Preliminary pilot data provide foundational support for our approach, indicating promising directions for identifying neural patterns associated with productive social interactions. The planned research will explore the neural correlates of social bond formation, informing the creation of a virtual peer learning partner in the field of Social Neuroergonomics. This protocol promises significant contributions to understanding the neural basis of social connectivity in children, while also offering a blueprint for designing empathetic and effective social AI tools, particularly for educational contexts.
Emotional Regulation as a Transdiagnostic Process of Emotional Disorders in Therapy: A Systematic Review and Meta-Analysis
Antuña-Camblor C, Gómez-Salas FJ, Burgos-Julián FA, González-Vázquez A, Juarros-Basterretxea J and Rodríguez-Díaz FJ
Several studies have shown that emotional regulation (ER) is a transdiagnostic construct of emotional disorders. Therefore, if therapy improves ER, it would improve psychological distress.
Bolstering the adaptive information processing model: a narrative review
Rydberg JA, Virgitti L and Tarquinio C
In recent years, several theoretical models have been suggested as complementary to the adaptative information processing model of eye movement desensitization and reprocessing therapy. A narrative review of such models was conducted to assess the contributions of each, as well as their convergences, contradictions, and potential complementarity. Seven theoretical models were identified. All focus on the effects of EMDR therapy as a comprehensive psychotherapy approach with its principles, procedures, and protocols. Several refer to concepts related to propositional or predictive processing theories. Overall, the contribution of these proposals does appear to bolster Shapiro's original AIP model, potentially offering additional depth and breadth to case conceptualization and treatment planning in clinical practice, as well as a more precise theoretical understanding. The current exploratory comparative analysis may serve as a preliminary baseline to guide research into the relative merit of suggested theoretical proposals to enhance current standards for the clinical practice and teaching of EMDR therapy.
Exploring the neural basis of non-invasive prehabilitation in brain tumour patients: An fMRI-based case report of language network plasticity
Boccuni L, Roca-Ventura A, Buloz-Osorio E, Leno-Colorado D, Martín-Fernández J, Cabello-Toscano M, Perellón-Alfonso R, Pariente Zorrilla JC, Laredo C, Garrido C, Muñoz-Moreno E, Bargalló N, Villalba G, Martínez-Ricarte F, Trompetto C, Marinelli L, Sacchet MD, Bartrés-Faz D, Abellaneda-Pérez K, Pascual-Leone A and Tormos Muñoz JM
Primary brain neoplasms are associated with elevated mortality and morbidity rates. Brain tumour surgery aims to achieve maximal tumour resection while minimizing damage to healthy brain tissue. Research on Neuromodulation Induced Cortical Prehabilitation (NICP) has highlighted the potential, before neurosurgery, of establishing new brain connections and transfer functional activity from one area of the brain to another. Nonetheless, the neural mechanisms underlying these processes, particularly in the context of space-occupying lesions, remain unclear. A patient with a left frontotemporoinsular tumour underwent a prehabilitation protocol providing 20 sessions of inhibitory non-invasive neuromodulation (rTMS and multichannel tDCS) over a language network coupled with intensive task training. Prehabilitation resulted in an increment of the distance between the tumour and the language network. Furthermore, enhanced functional connectivity within the language circuit was observed. The present innovative case-study exposed that inhibition of the functional network area surrounding the space-occupying lesion promotes a plastic change in the network's spatial organization, presumably through the establishment of novel functional pathways away from the lesion's site. While these outcomes are promising, prudence dictates the need for larger studies to confirm and generalize these findings.
The protocol for an observational Australian cohort study of CADASIL: The AusCADASIL study
Saks DG, Bajorek B, Catts VS, Bentvelzen AC, Jiang J, Wen W, Mather KA, Thalamuthu A, Huang-Lung J, Nivison-Smith L, Griffiths LR, Smith RA, Sexton A, James P, Jayasena T, Poljak A, Hansra GK, Hosoki S, Park A, Hillenbrand CM, van Wijngaarden P, Chander RJ, Humphrey S, Chen R, Kochan NA, Helman TJ, Levi C, Brodtmann A, O'Sullivan MJ, Markus R, Butcher K, Parsons M, Kovacic JC and Sachdev PS
Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL) is a rare genetic condition with a broad phenotypic presentation. This study aims to establish the first Australian cohort of individuals affected by CADASIL (AusCADASIL) and examine its clinical features and longitudinal course, and to investigate neuroimaging and blood biomarkers to assist in early diagnosis and identify disease progression.
Stress in autism (STREAM): A study protocol on the role of circadian activity, sleep quality and sensory reactivity
Gernert CC, Falter-Wagner CM, Noreika V, Jachs B, Jassim N, Gibbs K, Streicher J, Betts H and Bekinschtein TA
Mental health issues are markedly increased in individuals with autism, making it the number one research priority by stakeholders. There is a crucial need to use personalized approaches to understand the underpinnings of mental illness in autism and consequently, to address individual needs. Based on the risk factors identified in typical mental research, we propose the following themes central to mental health issues in autism: sleep difficulties and stress. Indeed, the prevalence of manifold circadian disruptions and sleep difficulties in autism, alongside stress related to sensory overload, forms an integral part of autistic symptomatology. This proof-of-concept study protocol outlines an innovative, individualised approach towards investigating the interrelationships between stress indices, sleep and circadian activation patterns, and sensory sensitivity in autism. Embracing an individualized methodology, we aim to collect 14 days of data per participant from 20 individuals with autism diagnoses and 20 without. Participants' sleep will be monitored using wearable EEG headbands and a sleep diary. Diurnal tracking of heart rate and electrodermal activity through wearables will serve as proxies of stress. Those objective data will be synchronized with subjective experience traces collected throughout the day using the Temporal Experience Tracing (TET) method. TET facilitates the quantification of relevant aspects of individual experience states, such as stress or sensory sensitivities, by providing a continuous multidimensional description of subjective experiences. Capturing the dynamics of subjective experiences phase-locked to neural and physiological proxies both between and within individuals, this approach has the potential to contribute to our understanding of critical issues in autism, including sleep problems, sensory reactivity and stress. The planned strives to provide a pathway towards developing a more nuanced and individualized approach to addressing mental health in autism.
Efficacy of clozapine versus standard treatment in adult individuals with intellectual disability and treatment-resistant psychosis (CLOZAID): study protocol of a multicenter randomized clinical trial
Alemany-Navarro M, Sánchez-Barbero B, Reguera-Pozuelo P, Altea-Manzano L, Gómez-Garrido A, Rocha-González I, Garrido-Torres N, Ruiz-Veguilla M, García-Cerro S, Rosso-Fernández CM, Villagrán-Moreno JM, Sarramea F, Cervilla-Ballesteros J, Martínez-Leal R, Mayoral-Cleries F, and Crespo-Facorro B
Intellectual disability (ID) affects approximately 1% of the worldwide population and individuals with ID have a higher comorbidity with mental illness, and specifically psychotic disorders. Unfortunately, among individuals with ID, limited research has been conducted since ID individuals are usually excluded from mental illness epidemiological studies and clinical trials. Here we perform a clinical trial to investigate the effectiveness of clozapine in the treatment of resistant psychosis in individuals with ID. The article highlights the complexity of diagnosing and treating psychopathological alterations associated with ID and advocates for more rigorous research in this field.
COSGAP: COntainerized Statistical Genetics Analysis Pipelines
Akdeniz BC, Frei O, Hagen E, Filiz TT, Karthikeyan S, Pasman J, Jangmo A, Bergstedt J, Shorter JR, Zetterberg R, Meijsen J, Sønderby IE, Buil A, Tesli M, Lu Y, Sullivan P, Andreassen OA and Hovig E
The collection and analysis of sensitive data in large-scale consortia for statistical genetics is hampered by multiple challenges, due to their non-shareable nature. Time-consuming issues in installing software frequently arise due to different operating systems, software dependencies, and limited internet access. For federated analysis across sites, it can be challenging to resolve different problems, including format requirements, data wrangling, setting up analysis on high-performance computing (HPC) facilities, etc. Easier, more standardized, automated protocols and pipelines can be solutions to overcome these issues. We have developed one such solution for statistical genetic data analysis using software container technologies. This solution, named COSGAP: "COntainerized Statistical Genetics Analysis Pipelines," consists of already established software tools placed into Singularity containers, alongside corresponding code and instructions on how to perform statistical genetic analyses, such as genome-wide association studies, polygenic scoring, LD score regression, Gaussian Mixture Models, and gene-set analysis. Using provided helper scripts written in Python, users can obtain auto-generated scripts to conduct the desired analysis either on HPC facilities or on a personal computer. COSGAP is actively being applied by users from different countries and projects to conduct genetic data analyses without spending much effort on software installation, converting data formats, and other technical requirements.
Occupational Carpal Tunnel Syndrome: a scoping review of causes, mechanisms, diagnosis, and intervention strategies
Rotaru-Zavaleanu AD, Lungulescu CV, Bunescu MG, Vasile RC, Gheorman V, Gresita A and Dinescu VC
Carpal Tunnel Syndrome (CTS) has traditionally been viewed as a specialized medical condition. However, its escalating prevalence among professionals across a multitude of industries has sparked substantial interest in recent years. This review aims to delve into CTS as an occupational disease, focusing on its epidemiological patterns, risk factors, symptoms, and management options, particularly emphasizing its relevance in professional environments. The complex interaction of anatomical, biomechanical, and pathophysiological factors that contribute to the development of CTS in different work settings underlines the critical role of ergonomic measures, prompt clinical identification, and tailored treatment plans in reducing its effects. Nevertheless, the challenges presented by existing research, including diverse methodologies and definitions, highlight the need for more unified protocols to thoroughly understand and tackle this issue. There's a pressing demand for more in-depth research into the epidemiology of CTS, its injury mechanisms, and the potential role of targeted medicine. Moreover, recognizing CTS's wider ramifications beyond personal health is essential. The economic burden associated with CTS-related healthcare costs, productivity losses, and compensation claims can significantly impact both businesses and the broader society. Therefore, initiatives aimed at preventing CTS through workplace interventions, education, and early intervention programs not only benefit the affected individuals but also contribute to the overall well-being of the workforce and economic productivity. By fostering a collaborative approach among healthcare professionals, employers, policymakers, and other stakeholders, we can strive towards creating safer and healthier work environments while effectively managing the challenges posed by CTS in occupational settings.

Rząd Z, Rog J, Kajka N, Szewczyk P, Krukow P and Karakuła-Juchnowicz H
Anorexia nervosa (AN) is a life-threatening disease with a low effectiveness of treatment. The high relapse and mortality rate indicate new treatment approaches are needed. Here, we represent the protocol for randomized clinical trial (RCT) of transcranial direct current stimulation (tDCS) efficiency in the AN treatment. The main purpose of the 3-week RCT is to determine the effect of tDCS on the mental state and advances in nutritional rehabilitation in patients with AN.
Development of an implementation plan for a school-based multimodal approach for depression and suicide prevention in adolescents
Jenniskens K, Rasing S, Popma A, Creemers D, Ghalit C, van Vuuren L, Mérelle S, Spijker J and van Nassau F
Strong Teens and Resilient Minds (STORM) is a multimodal, school-based approach for depression and suicide prevention in adolescents that is currently implemented in a region in the Netherlands. The STORM approach will be implemented in new regions in the coming years. This study used the implementation mapping protocol to report on the development of the STORM implementation plan. First, a needs assessment was conducted through semi-structured interviews with stakeholders and brainstorming sessions with regional programme leaders in the two regions that started implementing STORM in 2023. This led to the identification of six main barriers to implementation: high level of demands for schools, insufficient understanding of the programme content, insufficient network collaboration, no perceived relative advantage of STORM by stakeholders, lack of attention to sustainability, and high work pressure. Second, performance and change objectives were formulated based on these barriers. For example, a performance objective for potential providers was that they felt supported by STORM. Third, implementation strategies were selected from theory and translated into practical applications through brainstorming sessions with programme leaders. The following strategies were included in the implementation plan: collaborate with similar initiatives within the region, free up time for STORM tasks, tailor strategies, identify and prepare STORM champions, and promote network weaving. Last, a plan to evaluate the implementation of STORM and the application of the STORM implementation plan was formulated. Planned evaluation research will provide more insight into the usefulness and impact of the STORM implementation plan.
Brain organoids engineered to give rise to glia and neural networks after 90 days in culture exhibit human-specific proteoforms
Wenzel TJ and Mousseau DD
Human brain organoids are emerging as translationally relevant models for the study of human brain health and disease. However, it remains to be shown whether human-specific protein processing is conserved in human brain organoids. Herein, we demonstrate that cell fate and composition of unguided brain organoids are dictated by culture conditions during embryoid body formation, and that culture conditions at this stage can be optimized to result in the presence of glia-associated proteins and neural network activity as early as three-months Under these optimized conditions, unguided brain organoids generated from induced pluripotent stem cells (iPSCs) derived from male-female siblings are similar in growth rate, size, and total protein content, and exhibit minimal batch-to-batch variability in cell composition and metabolism. A comparison of neuronal, microglial, and macroglial (astrocyte and oligodendrocyte) markers reveals that profiles in these brain organoids are more similar to autopsied human cortical and cerebellar profiles than to those in mouse cortical samples, providing the first demonstration that human-specific protein processing is largely conserved in unguided brain organoids. Thus, our organoid protocol provides four major cell types that appear to process proteins in a manner very similar to the human brain, and they do so in half the time required by other protocols. This unique copy of the human brain and basic characteristics lay the foundation for future studies aiming to investigate human brain-specific protein patterning (e.g., isoforms, splice variants) as well as modulate glial and neuronal processes in an -like environment.

Cannabis use, mental health, and problematic Internet use in Quebec: A study protocol
Brodeur M, Jutras-Aswad D, Légaré AA, Morvannou A, Monson E, Cotton JC, Hakansson A, Parent V and Hudon C
Problematic Internet use is characterized by excessive use of online platforms that can result in social isolation, family problems, psychological distress, and even suicide. Problematic Internet use has been associated with cannabis use disorder, however knowledge on the adult population remains limited. In Quebec, cannabis use has significatively increased since 2018, and it is associated with various risks in public safety, public health, and mental health. This study aims to identify factors associated with problematic Internet use among adult cannabis users and to better understand their experiences.

Exploring the scope and applications of anti-doping measures in ultramarathon: an analysis of the positions of ultramarathon race organizers
Colangelo J, Smith A, Hachen S and Liebrenz M
With ultramarathon attracting burgeoning interest, evidence has emerged about doping behaviors. However, currently, research into the anti-doping policy landscape and the adoption of testing and athlete surveillance is limited, including the applicability of rubric from the World Anti-Doping Agency (WADA) and National Anti-Doping Organizations (NADOs). Consequently, it remains unclear if anti-doping provisions have been developed and enforced in ultramarathon, which is a timely consideration given growth in the sport.
Effects of esketamine and fluoxetine on depression-like behaviors in chronic variable stress: a role of plasma inflammatory factors
Chen H, Zhao X, Ma X, Ma H, Zhou C, Zhang Y, Peng Z, Xue S and Cai M
Mounting evidence has identified the rapid and sustained antidepressive and anxiolytic-like effects of esketamine. However, the underlying mechanism of this no-monoamine target rapid-onset antidepressant is still underexplored. Immune-inflammatory pathways and cell-mediated immune activation, mainly including inflammatory cytokines in plasma, play a pivotal role in the pathogenesis of major depressive disorder and are also a potential therapeutic target for MDD. The current study was designed to clarify the role of esketamine on the expression of plasma cytokines in a depressive-like model introduced by chronic variable stress (CVS). In this study, a 21-day consecutive CVS protocol was applied to produce depressive- and anxiety-like behaviors. After the single dose or 7-day repeated administration of esketamine or fluoxetine, the depressive- and anxiety-like behaviors and the expression of inflammatory cytokines in plasma were examined. Both a single dose of esketamine and 7-days repeated fluoxetine administration elicited anti-depressive and anxiolytic effects in mice exposed to CVS. Additionally, CVS produced significant changes in the plasma inflammatory factors, notably increasing the expression of IL-1β, IL-6, IL-8, IL-17A, TNFα, IL-4, IL-9, IL-24, IL-37, IFN-β, and CXCL12, while reducing IL-10 and IL-33. With the administration of esketamine and fluoxetine, CVS-produced inflammatory disturbances were partially normalized. Together, our findings provide a novel insight that acute esketamine treatment could rescue CVS-produced depressive-like and anxiety-like behaviors in mice by normalizing the expression of inflammatory cytokines; this effect was similar to the repeated administration of fluoxetine. These results contributed to the understating of rapid anti-depressant effects elicited by esketamine.
Retinal Tear Following Low-Frequency Repetitive Transcranial Magnetic Stimulation for Obsessive-Compulsive Disorder
Garip B, Buzkan B and Demir S
Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive form of brain stimulation that uses magnetic pulses to stimulate specific brain regions. Retina is being investigated whether the retina, which is also known as the brain's window to the outside world, is affected by the treatment.
A confounder controlled machine learning approach: Group analysis and classification of schizophrenia and Alzheimer's disease using resting-state functional network connectivity
Hassanzadeh R, Abrol A, Pearlson G, Turner JA and Calhoun VD
Resting-state functional magnetic resonance imaging (rs-fMRI) has increasingly been used to study both Alzheimer's disease (AD) and schizophrenia (SZ). While most rs-fMRI studies being conducted in AD and SZ compare patients to healthy controls, it is also of interest to directly compare AD and SZ patients with each other to identify potential biomarkers shared between the disorders. However, comparing patient groups collected in different studies can be challenging due to potential confounds, such as differences in the patient's age, scan protocols, etc. In this study, we compared and contrasted resting-state functional network connectivity (rs-FNC) of 162 patients with AD and late mild cognitive impairment (LMCI), 181 schizophrenia patients, and 315 cognitively normal (CN) subjects. We used confounder-controlled rs-FNC and applied machine learning algorithms (including support vector machine, logistic regression, random forest, and k-nearest neighbor) and deep learning models (i.e., fully-connected neural networks) to classify subjects in binary and three-class categories according to their diagnosis labels (e.g., AD, SZ, and CN). Our statistical analysis revealed that FNC between the following network pairs is stronger in AD compared to SZ: subcortical-cerebellum, subcortical-cognitive control, cognitive control-cerebellum, and visual-sensory motor networks. On the other hand, FNC is stronger in SZ than AD for the following network pairs: subcortical-visual, subcortical-auditory, subcortical-sensory motor, cerebellum-visual, sensory motor-cognitive control, and within the cerebellum networks. Furthermore, we observed that while AD and SZ disorders each have unique FNC abnormalities, they also share some common functional abnormalities that can be due to similar neurobiological mechanisms or genetic factors contributing to these disorders' development. Moreover, we achieved an accuracy of 85% in classifying subjects into AD and SZ where default mode, visual, and subcortical networks contributed the most to the classification and accuracy of 68% in classifying subjects into AD, SZ, and CN with the subcortical domain appearing as the most contributing features to the three-way classification. Finally, our findings indicated that for all classification tasks, except AD vs. SZ, males are more predictable than females.
