Local-structure-preservation and redundancy-removal-based feature selection method and its application to the identification of biomarkers for schizophrenia.

Accurate diagnosis of mental disorders is expected to be achieved through the identification of reliable neuroimaging biomarkers with the help of cutting-edge feature selection techniques. However, existing feature selection methods often fall short in capturing the local structural characteristics among samples and effectively eliminating redundant features, resulting in inadequate performance in disorder prediction. To address this gap, we propose a novel supervised method named local-structure-preservation and redundancy-removal-based feature selection (LRFS), and then apply it to the identification of meaningful biomarkers for schizophrenia (SZ). LRFS method leverages graph-based regularization to preserve original sample similarity relationships during data transformation, thus retaining crucial local structure information. Additionally, it introduces redundancy-removal regularization based on interrelationships among features to exclude similar and redundant features from high-dimensional data. Moreover, LRFS method incorporates l2,1 sparse regularization that enables selecting a sparse and noise-robust feature subset. Experimental evaluations on eight public datasets with diverse properties demonstrate the superior performance of our method over nine popular feature selection methods in identifying discriminative features, with average classification accuracy gains ranging from 1.30 % to 9.11 %. Furthermore, the LRFS method demonstrates superior discriminability in four functional magnetic resonance imaging (fMRI) datasets from 708 healthy controls (HCs) and 537 SZ patients, with an average increase in classification accuracy ranging from 1.89 % to 9.24 % compared to other nine methods. Notably, our method reveals reproducible and significant changes in SZ patients relative to HCs across the four datasets, predominantly in the thalamus-related functional network connectivity, which exhibit a significant correlation with clinical symptoms. Convergence analysis, parameter sensitivity analysis, and ablation studies further demonstrate the effectiveness and robustness of our method. In short, our proposed feature selection method effectively identifies discriminative and reliable features that hold the potential to be biomarkers, paving the way for the elucidation of brain abnormalities and the advancement of precise diagnosis of mental disorders.

Experiences of individuals with serious mental disorders in regular employment through the Individual Placement and Support model.

Introduction: This study shows the perspective, meaning and satisfaction perceived by people with Serious Mental Disorders during their experiences in regular employment. Methods: A mixed qualitative-quantitative methodology was used, applying semi-structured interview as qualitative information collection tool and the Indiana Job Satisfaction Scale as quantitative tool. The study period was from January 2021 to December 2022. A purposive sampling was performed with a sample of 24 people with Serious Mental Disorders who had obtained a job through an Individual Placement and Support (IPS) program during the study period. Semi-structured interview and the Indiana Job Satisfaction Scale were applied to this Serious Mental Disorder workers' sample. The Indiana Job Satisfaction Scale was also applied to a group of 24 workers without mental disorders in the same working conditions who served as control group. Results: The results of the analyses of the Serious Mental Disorder workers' narratives show that perception of work experience is conditioned by individual, environmental and social predictors, as well as external factors as determining variables. Quantitative results obtained by the Indiana Job Satisfaction Scale reveal levels of job satisfaction resembling those of the rest of workers without Serious Mental Disorder. Discussion: These findings reinforce the significance of employment in the recovery process for individuals with Serious Mental Disorders and emphasize the importance of understanding the subjective meaning individuals attribute to their work experiences.

Feuerstein Instrumental Enrichment Program for People With Schizophrenia After the First Episode of Psychosis: Protocol for an Open-Label Intervention Study.

BACKGROUND: Schizophrenia is a disorder associated with neurocognitive deficits that adversely affect daily functioning and impose an economic burden. Cognitive rehabilitation interventions, particularly during the early phases of illness, have been shown to improve cognition, functionality, and quality of life. The Feuerstein Instrumental Enrichment (FIE) program, based on the Mediated Learning Experience and the Structural Cognitive Modifiability theory, has been applied in various disorders, but its applicability in schizophrenia has not yet been clarified. OBJECTIVE: This study aims to investigate the effects of the FIE program on the functionality of patients with first-episode schizophrenia. METHODS: In total, 17 patients will be recruited for an open-label intervention consisting of twice-weekly sessions for 10 weeks. The primary outcome measure will be changes in the Goal Achievement Scale score. Maze task performance from the Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) battery will serve as a secondary outcome measure. At the same time, changes in Positive and Negative Syndrome Scale scores and other MATRICS domains will be analyzed as exploratory outcomes. Assessments will be administered before and after the intervention, with a follow-up period of 6 months. RESULTS: This trial was preregistered in The Brazilian Registry of Clinical Trials (RBR-4gzhy4s). By February 2024, 11 participants were enrolled in the training. Recruitment is expected to be completed by May 2024. Data analysis will be conducted between May and September 2024. The results are expected to be published in January 2025. CONCLUSIONS: This study may establish a protocol for the FIE program that uses mediation techniques for individuals in the early stages of schizophrenia. The results will add to the knowledge about strategies to promote cognitive skills and functional impairment in daily life. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/57031.

The Realities of Caring for a Person with a Mental Disorder in Rural and Remote Capricorn District of South Africa: A Qualitative Study.

In rural African communities, family caregivers shoulder the responsibility of caring for loved ones with mental disorders, often without professional support. This qualitative explorative study, conducted in Limpopo Province, South Africa, aimed to explore the realities of caring for a family member with a mental disorder in rural and remote Capricorn District, in order to uncover insights that can inform support systems, the academic community, interventions, and policies. Non-probability purposive sampling was used to ensure the reproducibility and validity of the results by focusing on participants who are actively involved in caregiving, living in the rural and remote of Capricorn District, in order to provide a comprehensive understanding of their experiences, and this resulted in 15 participants (13 females, 2 males). Data saturation determined the sample size, with data collected through in-depth interviews and analyzed using Tesch's open-coding method. The findings revealed that cultural and spiritual beliefs strengthen caregivers, who exhibit resilience and resourcefulness, yet face financial strain, career setbacks, social isolation, and health declines. The study underscores the critical role of healthcare professionals in recognizing and addressing the challenges faced by family caregivers, while also advocating for the academic community to prioritize the development and dissemination of educational programs focused on safe and ethical coping strategies for caregivers and for policymakers to develop comprehensive mental health services that are accessible and culturally sensitive to rural and remote communities. This is essential because the well-being of caregivers directly influences the rehabilitation and community integration outcomes for individuals with mental disorders.

Mobile mental health application use, and app feature preferences among individuals with mental disorders in Ethiopia: A cross-sectional survey.

BACKGROUND: Mobile health applications have been shown to assist in the treatment of mental illnesses, yet their potential remains underutilized. As supportive care, mental health applications use may be useful tools in improving mental health literacy and treatment outcomes, but patients' use of and interest in using these apps have not been studied in low-income countries like Ethiopia. This study explores the determinants of patients' mental health app use interests and app feature preferences. METHODS: A cross-sectional study was conducted with 419 outpatient individuals with mental health disorders at Amanuel Mental Specialized Hospital, Ethiopia, between October and November 2023, using a convenience sampling method. Patients' self-reported mental health app use, interests, attitudes, and app feature preferences were collected. A multivariate logistic regression model was used to identify the associated factors. RESULTS: Overall prevalence of not interested, somewhat interested, interested, and extremely interested in mental health app use was 5.3 %, 16.9 %, 27.7 %, and 50.1 % respectively. The proportion of current mental health apps use was low (21.2 %). Current mental health app use is associated with living in an urban area (AOR = 6.69, CI: 3.19-14) and having a higher education level (4.12 (2.02-8.04). Furthermore, app features such as psychoeducation, symptom tracking, and self-management techniques ranked as the most preferred app features. CONCLUSIONS: Most study participants were interested in using mental health apps, but only about one in four were using mental health apps. This suggests promise for their utility in the Ethiopian context. App developers and policymakers should consider rural residents', lower educational levels, and patient app preferences when developing these applications.

Effects of distant biofield energy healing on adults associated with psychological and mental health-related symptoms: a randomized, placebo-controlled, double-blind study.

Background: In recent years, popularity of Biofield energy healing therapy has increased tremendously parallel to conventional therapy. However, due to insufficient scientific studies on biofield therapies, authors planned this clinical trial to examine the safety and effectiveness of biofield therapy in treating symptoms of psychological and mental health and to explore parameters for its effectiveness. Methods: One hundred fourteen participants (55 male, 59 female) underwent clinical trials. This trial was randomized, placebo-controlled, three parallel-groups, double-blind, and single-center with subjects who have one or more psychological and mental symptoms. Two sessions of distant (virtual) biofield energy attunement were given on days 0 and 90 for about 5 minutes to the subjects of biofield intervention group (n=39). Besides, control (n=35) and sham control (n=40) group subjects also received kind of treatment in a similar manner to nullify baseline responses. Subjects were assessed by psychological questionnaire scoring using standard scale of assessment and safety parameters. Results: Perceived psychological symptoms/scores (fatigue/tiredness, sleep disturbances, stress, cognitive impairment, loss of memory, mental restlessness, emotional trauma, anxiety, depression, confusion, financial crises and dissatisfaction, low libido, motivation, confidence, lack of perception, relationship, and social behaviors, etc.) were significantly (p <.0001) improved in biofield intervention group compared to the naïve control and sham control groups. Besides, biofield intervention did not show any study-related adverse effects in all three groups throughout the trial. Conclusions: The distant (virtual) biofield energy healing therapy significantly improved psychological and mental health-related symptoms without affecting safety concerns, and improved overall health and quality of life.

New psychoactive substances - 96 cases of deaths related to their use based on the material originating from forensic toxicological practice.

Among the emerging investigative fields, forensic medicine and toxicology lead to analyzing fatalities in medico-legal expert opinion formulating. While discussing the problem, the authors have selected 96 fatal cases from their expert practice including the period from 2010 to 2023, in which deaths were connected with taking new psychoactive substances (NPS's) belonging to various chemical categories, mainly synthetic cathinones (SC), synthetic cannabinoids (SCan) and non-medical synthetic opioids (NSO). In the investigated cases, toxicological analysis revealed 37 NPS's and their 9 metabolites. The cases involved the use of SC's (64 cases - 67 %), Scan's, including their metabolites (10 cases - 10 %) and NSO's, including their metabolites (6 cases - 6 %). The remaining cases involved the simultaneous use of NSO with SC and/or SCan, including their metabolites (8 cases - 8 %), or SC with SCan (5 cases - 5 %). In three cases (3 %), compounds belonging to other groups were taken. In twenty-five cases, more than one NPS was found. Moreover, in twenty-seven cases, ethyl alcohol was also detected at the concentration range of 0.6-3.6 ‰. The concentration of xenobiotics determined in blood represented extensive ranges of concentration. The victims were at the age of 16-58 years of life. The group included eleven women (11 %). Generally, the deaths related to NPS's were predominantly of an accidental character (81 %), while the manner of death in sixteen cases (17 %) was suicide, including hanging (5 cases), jumping from a great height (3 cases), self-injury and exsanguination (1 case), as well as acute drug intoxication (6 cases) and intoxication with central nervous system hypoxia after an hanging (1 case). Among the analyzed cases there were two victims of homicide (2 %), in one of which the perpetrator being under the influence of the mixture of the synthetic opioid U-47700 and synthetic cannabinoid AB-FUBINACA. In twenty-eight cases, medications used in psychiatry were found, which suggested that the victims were struggling with mental problems before death. As it was implied by the available information, more than 36 % of the victims had mental problems.

[Electroconvulsive therapy in people with intellectual disability]. / Elektrokonvulsionstherapie bei Menschen mit Intelligenzminderung.

Electroconvulsive therapy (ECT) is a highly effective treatment option for severe mental illness. Although people with intellectual disability (ID) have similar prevalence rates of mental disorders in comparison to the general population their access to ECT remains challenging. A systematic literature review was carried out on treatment with ECT in patients with ID and a case report on a patient with ID who underwent ECT is presented, to highlight a typical clinical routine. A total of 100 articles with 208 different case reports were retrieved. In summary, the results underline the effectiveness of ECT in people with ID, with side effects comparable to those in the general population. The ECT is effective in the treatment of severe affective and psychotic disorders and particularly in people with catatonia. The use of ECT can improve the patient's mental health and quality of life and is often a life-saving treatment option. The prophylaxis of relapses should be included as early as possible in the planning process. Providing an easy access to ECT treatment for people with ID is corroborated by its effectiveness and is in line with the right to equal treatment in accordance with article 25 of the United Nations Convention on the Rights of Persons with Disabilities.

Plant extracts as emerging modulators of neuroinflammation and immune receptors in Alzheimer's pathogenesis.

Memory loss is becoming an increasingly significant health problem, largely due to Alzheimer's disease (AD), which disrupts the brain in several ways, including causing inflammation and weakening the body's defenses. This study explores the potential of medicinal plants as a source of novel therapeutic agents for AD. First, we tested various plant extracts against acetylcholinesterase (AChE) in vitro, following molecular docking simulations with key AD-related protein targets such as MAO-B, P-gp, GSK-3ß, and CD14. Rosemary extract was found to be the most inhibitory towards AChE. The compounds found in rosemary (oleanolic acid), sage (pinocembrin), and cinnamon (italicene) showed promise in potentially binding to MAO-B. These chemicals may interact with a key protein in the brain and alter the production and removal of amyloid-ß. Luteolin (from rosemary), myricetin (from sage), chamigrene, and italicene (from cinnamon) exhibited potential for inhibiting tau aggregation. Additionally, ursolic acid found in rosemary, sage, and chamigrene from cinnamon could modulate CD14 activity. For the first time, our findings shed light on the intricate interplay between neuroinflammation, neuroprotective mechanisms, and the immune system's role in AD. Further research is needed to validate the in vivo efficacy and safety of these plant-derived compounds, as well as their interactions with key protein targets, which could lead to the development of novel AD therapeutics.

Prevalence of anxiety, depression, and post-traumatic stress disorder among paramedic students: a systematic review and meta-analysis.

PURPOSE: There are elevated mental health concerns in paramedic students, but estimates vary between studies and countries, and no review has established the overall prevalence. This systematic review addressed this by estimating the global prevalence of common mental health disorders, namely anxiety, depression, and post-traumatic stress disorder (PTSD), in paramedic students internationally. METHODS: A systematic search of six databases, including MEDLINE, EMBASE, PsycINFO, CINAHL, Scopus, and medRxiv, was conducted to identify studies relating to mental health among paramedicine students. The search encompassed studies from inception until February 2023. To be considered for inclusion in the review, the studies had to report prevalence data on at least one symptom of anxiety, depression, or PTSD in paramedicine students, using quantitative validated scales. The quality of the studies was assessed using Joanna Briggs Institute (JBI) Checklist, which is a specific methodological tool for assessing prevalence studies. Subgroup analyses were not conducted due to insufficient data. RESULTS: 1638 articles were identified from the searches, and 193 full texts were screened, resulting in 13 papers for the systematic review and meta-analysis. The total number of participants was 1064 from 10 countries. The pooled prevalence of moderate PTSD was 17.9% (95% CI 14.8-21.6%), anxiety was 56.4% (95% CI 35,9-75%), and depression was at 34.7% (95% CI 23.4-48.1%). CONCLUSION: This systematic review and meta-analysis has found that paramedicine students globally exhibit a high prevalence of moderate PTSD, anxiety, and depression. The prevalence of these mental health conditions surpasses those among paramedic providers and the general population, as indicated by previous reviews. Further research is therefore warranted to determine appropriate support and interventions for this group.

Neural Basis of Pain Empathy Dysregulations in Mental Disorders - A Pre-registered Neuroimaging Meta-Analysis.

BACKGROUND: Pain empathy represents a fundamental building block of several social functions, which have been demonstrated to be impaired across various mental disorders by accumulating evidence from case-control functional magnetic resonance imaging (fMRI) studies. However, it remains unclear whether the dysregulations are underpinned by robust neural alterations across mental disorders. METHODS: This study utilized coordinate-based meta-analyses to quantitatively determine robust markers of altered pain empathy across mental disorders. To support the interpretation of the findings exploratory network-level and behavioral meta-analyses were conducted. RESULTS: Quantitative analysis of eleven case-control fMRI studies with data from 296 patients and 229 controls revealed patients with mental disorders exhibited increased pain empathic reactivity in the left anterior cingulate gyrus, adjacent medial prefrontal cortex, and right middle temporal gyrus, yet decreased activity in the left cerebellum IV/V and left middle occipital gyrus compared to controls. The hyperactive regions showed network-level interactions with the core default mode network (DMN) and were associated with affective and social cognitive domains. CONCLUSIONS: The findings suggest that pain-empathic alterations across mental disorders are underpinned by excessive empathic reactivity in brain systems involved in empathic distress and social processes, highlighting a shared therapeutic target to normalize basal social dysfunctions in mental disorders.

3-generation family histories of mental, neurologic, cardiometabolic, birth defect, asthma, allergy, and autoimmune conditions associated with autism: An open-source catalog of findings.

The relatively few conditions and family member types (e.g., sibling, parent) considered in investigations of family health history in autism spectrum disorder (ASD, or autism) limits understanding of the role of family history in autism etiology. For more comprehensive understanding and hypothesis-generation, we produced an open-source catalog of autism associations with family histories of mental, neurologic, cardiometabolic, birth defect, asthma, allergy, and autoimmune conditions. All live births in Denmark, 1980-2012, of Denmark-born parents (1,697,231 births), and their 3-generation family members were followed through April 10, 2017 for each of 90 diagnoses (including autism), emigration or death. Adjusted hazard ratios (aHR) were estimated via Cox regression for each diagnosis-family member type combination, adjusting for birth year, sex, birth weight, gestational age, parental ages at birth, and number of family member types of index person; aHRs also calculated for sex-specific co-occurrence of each disorder. We obtained 6462 individual family history aHRS across autism overall (26,840 autistic persons; 1.6% of births), by sex, and considering intellectual disability (ID); and 350 individual co-occurrence aHRS. Results are cataloged in interactive heat maps and down-loadable data files: https://ncrr-au.shinyapps.io/asd-riskatlas/ and interactive graphic summaries: https://public.tableau.com/app/profile/diana.schendel/viz/ASDPlots_16918786403110/e-Figure5. While primarily for reference material or use in other studies (e.g., meta-analyses), results revealed considerable breadth and variation in magnitude of familial health history associations with autism by type of condition, family member type, sex of the family member, side of the family, sex of the index person, and ID status, indicative of diverse genetic, familial, and nongenetic autism etiologic pathways. Careful attention to sources of autism likelihood in family health history, aided by our open data resource, may accelerate understanding of factors underlying neurodiversity.

Prevalence of harassment, abuse, and mental health among current and retired senior Swedish cheerleaders.

This study examined the prevalence of non-accidental violence, focusing on experienced harassment and abuse (HA), and mental health among current and retired Swedish competitive cheerleaders. An online survey was distributed to current and retired athletes in the Swedish cheerleading federation. The survey assessed perceived coach-athlete relationship, sport psychological safety, resilience, mental health, and experienced HA within the cheerleading environment. A total of 284 athletes (men = 5; women = 278; gender not disclosed = 1; current athletes = 211; retired athletes = 73) completed the survey. Psychological abuse was the most frequently reported HA form (current athletes = 21.6%; retired athletes = 53.5%), followed by neglect (current athletes = 5.4%; retired athletes: 26.8%) and physical abuse (current athletes = 3.9%; retired athletes = 12.7%). A high-quality coach-athlete relationship was identified as a protective factor for HA. Additionally, 33.1% and 8.9% of participants displayed scores indicating anxiety and depression caseness, while 63.8% reported a high level of wellbeing. Anxiety/depression scores above clinical cut-off were linked to injury episodes and a high level of wellbeing to a mentally healthy environment. Resilience was found to protect mental health overall. The high occurrence of reported psychological abuse and indications of anxiety/depression related to injury episodes suggest a need of attention towards prevention and athlete protection strategies in cheerleading environments.

An Epidemiological Study of Physical-Mental Multimorbidity in Youth: Une étude épidémiologique de la morbidité physique-mentale chez les jeunes.

OBJECTIVE: This epidemiological study estimated the lifetime prevalence of chronic physical illness (i.e., an illness that lasted or was expected to last ≥6 months) and 6-month prevalence of mental disorder and multimorbidity (i.e., ≥1 physical illness and ≥1 mental disorder) in youth. Associations between physical illness and mental disorder were quantified, including the number of illnesses. Secondary objectives examined factors associated with mental disorder, after controlling for physical illness. METHODS: Data come from 10,303 youth aged 4-17 years in the 2014 Ontario Child Health Study (OCHS). Physical illness was measured using a list of chronic conditions developed by Statistics Canada. Mental disorders were measured using the OCHS Emotional Behavioural Scales. The Health Utility Index Mark III assessed overall functional health. RESULTS: Weighted prevalence estimates showed 550,090 (27.8%) youth had physical illness, 291,986 (14.8%) had mental disorder, and 108,435 (5.4%) had multimorbidity. Physical illness was not associated with mental disorder. However, youth with 2 physical illnesses, as compared to no physical illnesses, had increased odds of having any mental (OR = 1.75 [1.08, 2.85]), mood (OR = 2.50 [1.39, 4.48]) and anxiety disorders (OR = 2.40 [1.33, 4.31]). Mean functional health scores demonstrated a dose-response association across health status categories, with the highest scores among healthy youth and the lowest scores among multimorbid youth (all p < .05). CONCLUSION: Chronic physical illness and mental disorders are prevalent in youth. Youths with 2 physical illnesses have a higher likelihood of mental disorders. Higher functional health scores protected against all mental disorders. Mental health interventions for youth should promote strong overall functional health.

Physical-Mental Multimorbidity in Ontario YouthPlain Language SummaryThis study examined mental disorders in Ontario youth with and without chronic physical illnesses. Youth with at least one physical illness and one mental disorder have physical-mental multimorbidity. 27.8% of youth had chronic physical illness (that lasted at least six months), 14.8% had mental disorder, and 5.4% had multimorbidity. Risk factors for any mental, mood, and anxiety disorders included living with two chronic physical illnesses. Overall functional health of youth declined from youth that were healthy (no physical illness or mental disorder), chronic physical illness only, mental illness only, to multimorbid youth. Youth mental health interventions should promote strong overall functional health.

Hospital-treated bipolar disorder in adolescence in Finland 1980-2010: Rehospitalizations, diagnostic stability, and mortality.

AIMS: Estimates of the occurrence of bipolar disorder among adolescents vary from country to country and from time to time. Long delays from first symptoms to diagnosis of bipolar disorder have been suggested. Studies among adults suggest increased mortality, particularly due to suicide and cardiovascular diseases. We set out to study the prognosis of adolescent onset bipolar disorder in terms of rehospitalizations, diagnostic stability, and mortality. METHODS: The study comprised a register-based follow-up of all adolescents admitted to psychiatric inpatient care for the first time in their lives at age 13-17 during the period 1980-2010. They were followed up in the National Care Register for Health Care and Causes of death registers until 31 December 2014. RESULTS: Incidence of bipolar disorder among 13- to 17-year-old adolescents over the whole study period was 2.8 per 100, 000 same aged adolescents, and across decades, the incidence increased six-fold. Patients with bipolar disorder during their first-ever inpatient treatment were rehospitalized more often than those treated for other reasons. Conversion from bipolar disorder to other diagnoses was far more common than the opposite. Mortality did not differ between those firstdiagnosed with bipolar disorder and those treated for other reasons. CONCLUSION: The incidence of adolescent onset bipolar disorder has increased across decades. The present study does not call for attention to delayed diagnosis of bipolar disorder. Adolescent onset bipolar disorders are severe disorders that often require rehospitalization, but diagnostic stability is modest. Mortality is comparable to that in other equally serious disorders.

Prevalence, severity and risk factors for mental disorders among sexual and gender minority young people: a systematic review of systematic reviews and meta-analyses.

Evidence suggests heightened prevalence and severity of mental disorders among sexual minority (SM) and gender minority (GM) young people. Several risk factors have been associated with these disparities. A systematic review of systematic reviews and meta-analysis was conducted to provide a comprehensive overview of the literature and to determine the field's current position. MEDLINE, PsycInfo, Scopus and Web of Science were searched in March 2022 and updated January 2024. Eligibility criteria were systematic reviews or meta-analyses assessing contemporaneous prevalence, severity and/or risk factors of mental disorders among SM or GM young people aged 25 and under. 42 reviews were included, all of which were low quality. The prevalence of depression among SM was 26% (95% CI 21-32%), and among GM was 46% (95% CI 36-56%). Greater depression severity was found among SM compared to heterosexual young people, with a significant albeit small effect size (Hedges' g = 0.38, 95% CI = 0.25 to 0.50); effect sizes were similar when separating by gender. GM also reported greater symptom severity compared to cisgender young people. Other mental disorders were more prevalent compared to those reported in the general population, and of greater severity compared to heterosexual/cisgender young people. Several proximal and distal risk factors were focused upon within the systematic reviews identified. Past systematic reviews consistently indicate a heightened risk of mental disorders among SM and GM young people. Services need to be aware of these disparities and adapt their care accordingly.

A scoping review about the portrayal of depression and anxiety in mainstream and social media.

Media portrayal of mental disorders has a significant impact on awareness and stigma. Given the high prevalence of depression and anxiety as mental disorders, it is crucial to understand how they are represented. This scoping review aimed to map the existing literature on the portrayal of depression and anxiety in mainstream and social media. A comprehensive search was conducted in PubMed and PsychInfo, resulting in the inclusion of 20 records that predominantly examined social media and newspapers. Findings indicate that social media discussions on depression were mostly supportive and non-stigmatising. Public figures and role models played a significant role in encouraging open communication. Research on newspapers and other media forms yielded mixed results yet leaning towards positive portrayals. Limited studies explored anxiety portrayal. While acknowledging potential limitations in generalisability, this review emphasises the importance of accurately depicting mental health in media, particularly on social media platforms, while highlighting the need for broader investigations into anxiety representation.

Application of Facial Expression Analysis Technology in Violence Risk Assessment of Individuals with Mental Disorders in Supervised Settings.

OBJECTIVES: To explore the association between violent behaviors and emotions in individuals with mental disorders, to evaluate the application value of facial expression analysis technology in violence risk assessment of individuals with mental disorders in supervised settings, and to provide a reference for violence risk assessment. METHODS: Thirty-nine male individuals with mental disorders in supervised settings were selected, the participant risk of violence, cognitive function, psychiatric symptoms and severity were assessed using the Modified Overt Aggression Scale (MOAS), the Historical, Clinical, Risk Management-Chinese version(HCR-CV), the Positive and Negative Syndrome Scale (PANSS) and the Brief Psychiatric Rating Scale (BPRS). An emotional arousal was performed on the participants and the intensity of their emotions and facial expression action units was recorded before, during and after the arousal. One-way analysis of variance (ANOVA) was used to compare the differences in the intensity of emotions and facial expression action units before, during and after the arousal. Pearson correlation analysis was used to calculate the correlations between the intensity of the seven basic emotional facial expressions and the scores of the assessment scales. RESULTS: The intensity difference of sadness, surprise and fear in different time periods was statistically significant (P<0.05). The intensity of the left medial eyebrow lift action unit was found significantly different before and after the emotional arousal (P<0.05). The intensity of anger was positively correlated with the Modified Overt Aggression Scale score throughout the experiment (P<0.05). CONCLUSIONS: Eye action units such as eyebrow lifting, eyelid tightening and upper eyelid lifting can be used as effective action units to identify sadness, anger and other negative emotions associated with violent behaviors. Facial expression analysis technology can be used as an auxiliary tool to assess the potential risk of violence in individuals with mental disorders in supervised settings.

Examining the mental health services among people with mental disorders: a literature review.

BACKGROUND: Mental disorders are a significant contributor to disease burden. However, there is a large treatment gap for common mental disorders worldwide. This systematic review summarizes the factors associated with mental health service use. METHODS: PubMed, Scopus, and the Web of Science were searched for articles describing the predictors of and barriers to mental health service use among people with mental disorders from January 2012 to August 2023. The initial search yielded 3230 articles, 2366 remained after removing duplicates, and 237 studies remained after the title and abstract screening. In total, 40 studies met the inclusion and exclusion criteria. RESULTS: Middle-aged participants, females, Caucasian ethnicity, and higher household income were more likely to access mental health services. The use of services was also associated with the severity of mental symptoms. The association between employment, marital status, and mental health services was inconclusive due to limited studies. High financial costs, lack of transportation, and scarcity of mental health services were structural factors found to be associated with lower rates of mental health service use. Attitudinal barriers, mental health stigma, and cultural beliefs also contributed to the lower rates of mental health service use. CONCLUSION: This systematic review found that several socio-demographic characteristics were strongly associated with using mental health services. Policymakers and those providing mental health services can use this information to better understand and respond to inequalities in mental health service use and improve access to mental health treatment.

Oral health knowledge, attitudes, and practices of people living with mental illness: a mixed-methods systematic review.

People living with mental illness experience poorer oral health outcomes compared to the general population, yet little is known about their oral health knowledge, attitudes, and practices. The aim of this mixed-methods systematic review was to synthesise evidence regarding oral health knowledge, attitudes, and practices of people living with mental illness to inform preventative strategies and interventions. Database searches were conducted in PubMed, MEDLINE, PsycINFO, CINAHL, ProQuest, and Scopus with no limitations placed on the year of study. All studies available in the English language, that explored the oral health knowledge, attitudes, and/or practices of people with a mental illness were included. Articles were excluded if they primarily pertained to intellectual disability, behavioural and psychological symptoms of dementia, drug and alcohol or substance use, or eating disorders. A thematic synthesis was undertaken of 36 studies (26 high-moderate quality), resulting in 3 themes and 9 sub-themes. Study participants ranged from n = 7 to n = 1095 and aged between 15-83 years with most having a diagnosis of schizophrenia, schizoaffective, or bipolar affective disorder. People diagnosed with a mental illness were found to have limited oral health knowledge, particularly regarding the effects of psychotropic medication. Various barriers to oral health care were identified, including high dental costs, the negative impact of mental illness, dental fears, lack of priority, and poor communication with dental and health care providers. Study participants often displayed a reduced frequency of tooth brushing and dental visits. The findings highlight the potential for mental health care providers, oral health and dental professionals, mental health consumers, and carers to work together more closely to improve oral health outcomes for people with mental illness. The systematic review protocol is registered with the International Prospective Register of Systematic Reviews (PROSPERO), (registration ID CRD42022352122).
