Behavioral variant frontotemporal dementia (bvFTD) is a neurodegenerative disorder characterized by diverse and prominent changes in behavior and personality. One of the greatest challenges in bvFTD is to capture, measure and predict its disease progression, due to clinical, pathological and genetic heterogeneity. Availability of reliable outcome measures is pivotal for future clinical trials and disease monitoring. Detection of change should be objective, clinically meaningful and easily assessed, preferably associated with a biological process. The purpose of this scoping review is to examine the status of longitudinal studies in bvFTD, evaluate current assessment tools and propose potential progression markers. A systematic literature search (in PubMed and Embase.com) was performed. Literature on disease trajectories and longitudinal validity of frequently-used measures was organized in five domains: global functioning, behavior, (social) cognition, neuroimaging and fluid biomarkers. Evaluating current longitudinal data, we propose an adaptive battery, combining a set of sensitive clinical, neuroimaging and fluid markers, adjusted for genetic and sporadic variants, for adequate detection of disease progression in bvFTD.

Review
BACKGROUND
Unaddressed early-stage mental health issues, including stress, anxiety, and mild depression, can become a burden for individuals in the long term. Digital phenotyping involves capturing continuous behavioral data via digital smartphone devices to monitor human behavior and can potentially identify milder symptoms before they become serious.
OBJECTIVE
This systematic literature review aimed to answer the following questions: (1) what is the evidence of the effectiveness of digital phenotyping using smartphones in identifying behavioral patterns related to stress, anxiety, and mild depression? and (2) in particular, which smartphone sensors are found to be effective, and what are the associated challenges?
METHODS
We used the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) process to identify 36 papers (reporting on 40 studies) to assess the key smartphone sensors related to stress, anxiety, and mild depression. We excluded studies conducted with nonadult participants (eg, teenagers and children) and clinical populations, as well as personality measurement and phobia studies. As we focused on the effectiveness of digital phenotyping using smartphones, results related to wearable devices were excluded.
RESULTS
We categorized the studies into 3 major groups based on the recruited participants: studies with students enrolled in universities, studies with adults who were unaffiliated to any particular organization, and studies with employees employed in an organization. The study length varied from 10 days to 3 years. A range of passive sensors were used in the studies, including GPS, Bluetooth, accelerometer, microphone, illuminance, gyroscope, and Wi-Fi. These were used to assess locations visited; mobility; speech patterns; phone use, such as screen checking; time spent in bed; physical activity; sleep; and aspects of social interactions, such as the number of interactions and response time. Of the 40 included studies, 31 (78%) used machine learning models for prediction; most others (n=8, 20%) used descriptive statistics. Students and adults who experienced stress, anxiety, or depression visited fewer locations, were more sedentary, had irregular sleep, and accrued increased phone use. In contrast to students and adults, less mobility was seen as positive for employees because less mobility in workplaces was associated with higher performance. Overall, travel, physical activity, sleep, social interaction, and phone use were related to stress, anxiety, and mild depression.
CONCLUSIONS
This study focused on understanding whether smartphone sensors can be effectively used to detect behavioral patterns associated with stress, anxiety, and mild depression in nonclinical participants. The reviewed studies provided evidence that smartphone sensors are effective in identifying behavioral patterns associated with stress, anxiety, and mild depression.

BACKGROUND
Hypersexuality (HS) accompanying neurological conditions remains poorly characterized despite profound psychosocial impacts. We aimed to systematically review the literature on HS in patients with neurological disorders. We conducted a systematic review to identify studies that reported HS in neurological disorders. HS was defined as a condition characterized by excessive and persistent preoccupation with sexual thoughts, urges, and behaviors that cause significant distress or impairment in personal, social, or occupational functioning. Data on demographics, assessment techniques, associated elements, phenotypic manifestations, and management strategies were also extracted. The final analysis included 79 studies on HS, encompassing 32 662 patients across 81 cohorts with neurological disorders. Parkinson's disease was the most frequently studied condition (55.6%), followed by various types of dementia (12.7%). Questionnaires were the most common assessment approach for evaluating HS, although the techniques varied substantially. Alterations in the dopaminergic pathways have emerged as contributing mechanisms based on the effects of medication cessation. However, standardized treatment protocols still need to be improved, with significant heterogeneity in documented approaches. Critical deficiencies include risks of selection bias in participant sampling, uncontrolled residual confounding factors, and lack of blinded evaluations of reported outcomes. Despite growth in the last decade, research on HS remains limited across neurological conditions, with lingering quality and methodological standardization deficits. Key priorities include advancing assessment tools, elucidating the underlying neurobiology, and formulating management guidelines.

Meta-Analysis
OBJECTIVE
Study the efficacy of digital health interventions in enhancing patient activation and identify the distinct features of these interventions using the WHO classification system.
METHODS
Asystematic reviewand meta-analysis were carried out according to the PRISMA guidelines. A search was conducted in Scopus, PubMed, and ProQuest. Randomized controlled trials (RCT), quasi-randomized controlled trials, and before-and-after studies enrolling patients ≥ 18 years of age with the Patient Activation Measure (PAM) score measurement and contain digital intervention with any aspects of health education or health-related behavior were included. The Downs and Black quality assessment tool was used to assess the quality of the articles.
RESULTS
In the three different types of meta-analyses, implementing the intervention led to a PAM score increase (Mean Difference (M.D.)), ranging from a minimum of (MD = 0.2014, 95 % CI = 0.0871-0.3158) and a highly significant p-value 0.0006 to a maximum of (MD = 2.7882, 95 % CI = 1.5558-4.0206) and a p-value < .0001. While the M.D. score of 0.2014 may seem relatively low, it is enough to elevate the patient from one activation level to a higher one out of the four activation levels.
CONCLUSION AND PRACTICE IMPLICATIONS
The results suggest the effectiveness of digital health interventions on patient activation across diverse settings and contexts, implying potential generalizability. Using WHO classification, all examined digital interventions addressed the challenges of information, utilization, and efficiency in the health system, but not equity-related challenges. The study recognized online health communities (OHCs) as a subset of digital interventions that enhance patient activation through social support.

BACKGROUND
Studies have shown that music therapy can be used as a therapeutic aid for clinical disorders. To evaluate the effects of music therapy (MT) on language communication and social skills in children with autism spectrum disorder (ASD), a meta-analysis was performed on eligible studies in this field.
METHODS
A systematic search was conducted in eight databases: PubMed, Embase, Web of Science, Cochrane Library databases, the China National Knowledge Infrastructure (CNKI), Wanfang Data, the Chinese Biomedical Literature (CBM) Database, and the VIP Chinese Science and Technology Periodicals Database. The standard mean difference (SMD) values were used to evaluate outcomes, and the pooled proportions and SMD with their 95% confidence intervals (CIs) were also calculated.
RESULTS
Eighteen randomized controlled trial (RCT) studies were included, with a total of 1,457 children with ASD. This meta-analysis revealed that music therapy improved their language communication [SMD = -1.20; 95%CI -1.45, -0.94; (17) = 84.17, = 80%, < 0.001] and social skills [SMD = -1. 13; 95%CI -1.49, -0.78; (17) = 162.53, = 90%, < 0.001]. In addition, behavior [SMD = -1.92; 94%CI -2.56, -1.28; (13) = 235.08, = 95%, < 0.001], sensory perception [SMD = -1.62; 95%CI -2.17, -1.08; (16) = 303.80, = 95%, < 0.001], self-help [SMD = -2. 14; 95%CI -3.17, -1.10; (6) = 173.07, = 97%, < 0.001] were all improved.
CONCLUSION
Music therapy has a positive effect on the improvement of symptoms in children with ASD.

Meta-Analysis Review
BACKGROUND
Because of wars, conflicts, persecutions, human rights violations, and humanitarian crises, about 84 million people are forcibly displaced around the world; the great majority of them live in low- and middle-income countries (LMICs). People living in humanitarian settings are affected by a constellation of stressors that threaten their mental health. Psychosocial interventions for people affected by humanitarian crises may be helpful to promote positive aspects of mental health, such as mental well-being, psychosocial functioning, coping, and quality of life. Previous reviews have focused on treatment and mixed promotion and prevention interventions. In this review, we focused on promotion of positive aspects of mental health.
OBJECTIVES
To assess the effects of psychosocial interventions aimed at promoting mental health versus control conditions (no intervention, intervention as usual, or waiting list) in people living in LMICs affected by humanitarian crises.
SEARCH METHODS
We searched CENTRAL, MEDLINE, Embase, and seven other databases to January 2023. We also searched the World Health Organization's (WHO) International Clinical Trials Registry Platform and ClinicalTrials.gov to identify unpublished or ongoing studies, and checked the reference lists of relevant studies and reviews.
SELECTION CRITERIA
Randomised controlled trials (RCTs) comparing psychosocial interventions versus control conditions (no intervention, intervention as usual, or waiting list) to promote positive aspects of mental health in adults and children living in LMICs affected by humanitarian crises. We excluded studies that enrolled participants based on a positive diagnosis of mental disorder (or based on a proxy of scoring above a cut-off score on a screening measure).
DATA COLLECTION AND ANALYSIS
We used standard Cochrane methods. Our primary outcomes were mental well-being, functioning, quality of life, resilience, coping, hope, and prosocial behaviour. The secondary outcome was acceptability, defined as the number of participants who dropped out of the trial for any reason. We used GRADE to assess the certainty of evidence for the outcomes of mental well-being, functioning, and prosocial behaviour.
MAIN RESULTS
We included 13 RCTs with 7917 participants. Nine RCTs were conducted on children/adolescents, and four on adults. All included interventions were delivered to groups of participants, mainly by paraprofessionals. Paraprofessional is defined as an individual who is not a mental or behavioural health service professional, but works at the first stage of contact with people who are seeking mental health care. Four RCTs were carried out in Lebanon; two in India; and single RCTs in the Democratic Republic of the Congo, Jordan, Haiti, Bosnia and Herzegovina, the occupied Palestinian Territories (oPT), Nepal, and Tanzania. The mean study duration was 18 weeks (minimum 10, maximum 32 weeks). Trials were generally funded by grants from academic institutions or non-governmental organisations. For children and adolescents, there was no clear difference between psychosocial interventions and control conditions in improving mental well-being and prosocial behaviour at study endpoint (mental well-being: standardised mean difference (SMD) 0.06, 95% confidence interval (CI) -0.17 to 0.29; 3 RCTs, 3378 participants; very low-certainty evidence; prosocial behaviour: SMD -0.25, 95% CI -0.60 to 0.10; 5 RCTs, 1633 participants; low-certainty evidence), or at medium-term follow-up (mental well-being: mean difference (MD) -0.70, 95% CI -2.39 to 0.99; 1 RCT, 258 participants; prosocial behaviour: SMD -0.48, 95% CI -1.80 to 0.83; 2 RCT, 483 participants; both very low-certainty evidence). Interventions may improve functioning (MD -2.18, 95% CI -3.86 to -0.50; 1 RCT, 183 participants), with sustained effects at follow-up (MD -3.33, 95% CI -5.03 to -1.63; 1 RCT, 183 participants), but evidence is very uncertain as the data came from one RCT (both very low-certainty evidence). Psychosocial interventions may improve mental well-being slightly in adults at study endpoint (SMD -0.29, 95% CI -0.44 to -0.14; 3 RCTs, 674 participants; low-certainty evidence), but they may have little to no effect at follow-up, as the evidence is uncertain and future RCTs might either confirm or disprove this finding. No RCTs measured the outcomes of functioning and prosocial behaviour in adults.
AUTHORS' CONCLUSIONS
To date, there is scant and inconclusive randomised evidence on the potential benefits of psychological and social interventions to promote mental health in people living in LMICs affected by humanitarian crises. Confidence in the findings is hampered by the scarcity of studies included in the review, the small number of participants analysed, the risk of bias in the studies, and the substantial level of heterogeneity. Evidence on the efficacy of interventions on positive mental health outcomes is too scant to determine firm practice and policy implications. This review has identified a large gap between what is known and what still needs to be addressed in the research area of mental health promotion in humanitarian settings.

BACKGROUND
Mild cognitive impairment (MCI) is commonly defined as a transitional subclinical state between normal aging and dementia. A growing body of research indicates that health behaviors may play a protective role against cognitive decline and could potentially slow down the progression from MCI to dementia. The aim of this study is to conduct a bibliometric analysis of literature focusing on health behaviors and MCI to summarize the factors and evidence regarding the influence of health behaviors on MCI.
METHODS
The study performed a bibliometric analysis by retrieving publications from the Science Citation Index and Social Sciences Citation Index sub-databases within the Web of Science Core Collection. Utilizing VOSviewer and CiteSpace software, a total of 2,843 eligible articles underwent co-citation, co-keywords, and clustering analyses. This methodology aimed to investigate the current status, trends, major research questions, and potential future directions within the research domain.
RESULTS
The bibliometric analysis indicates that research on healthy behaviors in individuals with MCI originated in 2002 and experienced rapid growth in 2014, reflecting the increasing global interest in this area. The United States emerged as the primary contributor, accounting for more than one-third of the total scientific output with 982 articles. Journals that published the most articles on MCI-related health behaviors included "Journal of Alzheimer's Disease," "Neurobiology of Aging," "Frontiers in Aging Neuroscience," and other geriatrics-related journals. High-impact papers identified by VOSviewer predominantly cover concepts related to MCI, such as diagnostic criteria, assessment, and multifactorial interventions. Co-occurrence keyword analysis highlights five research hotspots in health behavior associated with MCI: exercise, diet, risk factors and preventive measures for dementia, cognitive decline-related biomarkers, and clinical trials.
CONCLUSION
This study provides a comprehensive review of literature on health behavior in individuals with MCI, emphasizing influential documents and journals. It outlines research trends and key focal points, offering valuable insights for researchers to comprehend significant contributions and steer future studies.

Review
This review synthesises individual differences in neural processes related to emotion regulation (ER). It comprises individual differences in self-reported and physiological regulation success, self-reported ER-related traits, and demographic variables, to assess their correlation with brain activation during ER tasks. Considering region-of-interest (ROI) and whole-brain analyses, the review incorporated data from 52 functional magnetic resonance imaging studies. Results can be summarized as follows: (1) Self-reported regulation success (assessed by emotional state ratings after regulation) and self-reported ER-related traits (assessed by questionnaires) correlated with brain activity in the lateral prefrontal cortex. (2) Amygdala activation correlated with ER-related traits only in ROI analyses, while it was associated with regulation success in whole-brain analyses. (3) For demographic and physiological measures, there was no systematic overlap in effects reported across studies. In showing that individual differences in regulation success and ER-related traits can be traced back to differences in the neural activity of brain regions associated with emotional reactivity (amygdala) and cognitive control (lateral prefrontal cortex), our findings can inform prospective personalised intervention models.

Review
BACKGROUND
This systematic review contributes to the understanding of the characteristics of built food environments that may be associated with choices of alternative protein foods (APF). Using the built food environment typology proposed by Downs et al., we investigated various environmental structures (e.g., supermarkets, other retailers, farmers' markets, restaurants, schools, and online vendors) and the characteristics that may facilitate or hinder consumers' choices. For example, facilitators and barriers may refer to the physical characteristics of environmental structures, food presentation practices, the organizational strategies or policies operating in the setting, or the actions that retailers or consumers engage in while selling, serving, choosing, trying, or purchasing APF in these environmental structures.
METHODS
A systematic review (PROSPERO database preregistration; no. CRD42023388700) was conducted by searching 13 databases for peer-reviewed journals focusing on the fields of economics and business, agriculture, medical sciences, and social sciences. Data searches, coding, and quality evaluations were conducted by at least 2 researchers. A total of 31 papers (36 original studies) were included. The risk of bias was evaluated with the Joanna Briggs Institute quality evaluation tool, with 24 publications presenting low risk of bias.
RESULTS
The findings indicate that perceived and actual availability facilitate consumers' APF choices across a built food environment. Several barriers/facilitators were associated with APF choices in specific types of built food environments: the way food is presented in produce sections (supermarkets), consumer habits in terms of green and specialty shopping (grocery stores), and mismatches among retailer actions in regard to making APF available in one type of food environment structure (e-commerce) and consumers' preferences for APF being available in other food environment structures (supermarkets, grocery stores). The effect of a barrier/facilitator may depend on the APF type; for example, social norms regarding masculinity were a barrier affecting plant-based APF choices in restaurants, but these norms were not a barrier affecting the choice of insect-based APF in restaurants.
CONCLUSIONS
Addressing barriers/facilitators identified in this review will help in developing environment-matching interventions that aim to make alternative proteins mainstream.

Meta-Analysis
BACKGROUND
Humanitarian crises and disasters affect millions of people worldwide. Humanitarian aid workers are civilians or professionals who respond to disasters and provide humanitarian assistance. In doing so, they face several stressors and traumatic exposures. Humanitarian aid workers also face unique challenges associated with working in unfamiliar settings.
OBJECTIVE
To determine the occurrence of and factors associated with mental ill-health among humanitarian aid workers.
SEARCH STRATEGY
CINAHL plus, Cochrane library, Global Health, Medline, PubMed, Web of Science were searched from 2005-2020. Grey literature was searched on Google Scholar.
SELECTION CRITERIA
PRISMA guidelines were followed and after double screening, studies reporting occurrence of mental ill-health were included. Individual narratives and case studies were excluded, as were studies that reported outcomes in non-humanitarian aid workers.
DATA ANALYSIS
Data on occurrence of mental ill-health and associated factors were independently extracted and combined in a narrative summary. A random effects logistic regression model was used for the meta-analysis.
MAIN RESULTS
Nine studies were included with a total of 3619 participants, reporting on five types of mental ill-health (% occurrence) including psychological distress (6.5%-52.8%); burnout (8.5%-32%); anxiety (3.8%-38.5%); depression (10.4%-39.0%) and post-traumatic stress disorder (0% to 25%). Hazardous drinking of alcohol ranged from 16.2%-50.0%. Meta-analysis reporting OR (95% CI) among humanitarian aid workers, for psychological distress was 0.45 (0.12-1.64); burnout 0.34 (0.27-0.44); anxiety 0.22 (0.10-0.51); depression 0.32 (0.18-0.57) and PTSD 0.11 (0.03-0.39). Associated factors included young age, being female and pre-existing mental ill-health.
CONCLUSIONS
Mental ill-health is common among humanitarian aid workers, has a negative impact on personal well-being, and on a larger scale reduces the efficacy of humanitarian organisations with delivery of aid and retention of staff. It is imperative that mental ill-health is screened for, detected and treated in humanitarian aid workers, before, during and after their placements. It is essential to implement psychologically protective measures for individuals working in stressful and traumatic crises.
