Many children and young people (CYP) with significant mental health difficulties face barriers to accessing care from mental health services, impacting their clinical outcomes and recovery. Sociodemographic and socioeconomic factors may contribute to inequalities in access and outcomes.
Aims
To investigate the roles of sociodemographic, socioeconomic and clinical factors in influencing access to services, receipt of clinical care or diagnoses and clinical outcomes.
Method
Using data from a large, nationally representative, randomised controlled trial in England (STADIA), 1225 children aged 5–17 years and with emotional difficulties referred to child and adolescent mental health services (CAMHS) were followed up over 18 months post-referral to investigate predictors of referral acceptance, receipt of care and their clinical outcomes.
Results
Older CYP (for each 1-year increase in age, odds ratio 1.07, 95% CI: 1.02, 1.11) and those living in the least deprived neighbourhoods (deprivation index, least versus most deprived quintile: odds ratio 1.60, 95% CI: 1.05, 2.43) were more likely to have their referral accepted by CAMHS. Clinical severity (i.e. scoring above cut-off for symptoms and/or impact) was not associated with receipt of a clinical diagnosis or treatment/intervention. At 12-month post-referral, 61% met mental health ‘caseness’ criteria (v. 67% at baseline). CYP living in less deprived neighbourhoods had better clinical outcomes at 12-month follow-up (least versus most deprived quintile: odds ratio 0.49, 95% CI: 0.30, 0.81, for meeting caseness criteria, i.e. the presence of clinically significant symptoms and impairment). Females were more likely than males to have clinically significant levels of depression at 12-month follow-up (odds ratio 1.77, 95% CI: 1.28, 2.45).
Conclusions
There appear to be sociodemographic and socioeconomic inequalities in access to care and outcomes for clinically referred CYP with emotional mental health difficulties, with limited improvements in clinical outcomes 1 year following referral to CAMHS. CYP living in more deprived areas and younger children appear less likely to receive help, hampering earlier intervention efforts even in help-seeking populations.
Malnutrition in children remains a major global public health concern, especially in sub-Saharan Africa. A cross-sectional study was conducted among 120 children, with a sub-sample of 23 children selected for a 3-day weighed food intake assessment. Data were collected using a validated questionnaire, anthropometric measurements, and dietary intake records. Analysis was performed using SPSS version 21 and results were presented as means, frequencies, and percentages. The daily energy intake of children aged 4 and 5 years was below the recommended levels (74.1% and 64.3%, respectively). However, children aged 2 and 3 years had adequate energy intakes, exceeding the recommendations (102.4% and 111.5%). Iron intake across all age groups was below the recommended dietary intake. Intake of B-complex vitamins (B1, B2, B3) among 2-, 3-, and 5-year-olds exceeded recommended levels. Calcium intake was consistently low across all age groups (2 years: 37.5%, 3 years: 44.6%, 4 years: 23.5%, 5 years: 24.7%), this is due to low consumption of protein food sources and vegetables rich in calcium. Key factors influencing low nutritional status included inadequate consumption of high protein food sources, overreliance on carbohydrate food (cassava flour), poor consumption of fruits and vegetables, and inability to access food due to sickness. The study highlights suboptimal intake of energy and essential micronutrients among orphanage children, particularly older age groups. Nutrition education, improved feeding practices, and increased dietary diversity are essential to improve the nutritional status of children in orphanages.
The relationship between mild ketosis and metabolic syndrome (MetS) remains unclear. We aimed to investigate the association between serum ketone levels and MetS and to examine how genetic and lifestyle factors influence this relationship. We conducted a cross-sectional observational study using data from the UK Biobank, comprising 269 178 participants. Participants were categorised into low and high serum ketone groups based on β-hydroxybutyrate levels (cut-off: 0·12 mM). Dietary patterns were assessed using validated questionnaires, and a polygenic risk score (PRS) was generated to examine genetic influences on ketone metabolism. Individuals with higher ketone levels showed significantly lower MetS prevalence, with reduced BMI, waist circumference, TAG and glucose levels, alongside higher HDL-cholesterol. These individuals also exhibited distinct dietary patterns, characterised by lower carbohydrate (CHO) and higher fat intake, as well as increased physical activity. The PRS was inversely associated with MetS risk, particularly for abdominal obesity, TAG and HDL-cholesterol components. Notably, PRS modified the relationship between plant-based diet and ketone levels, with stronger positive associations observed in individuals with higher PRS. However, a high CHO diet showed weaker associations with PRS. In conclusion, genetic predisposition influenced ketone metabolism and its protective association with MetS risk. The interaction between genetic predisposition and lifestyle factors has crucial clinical implications for developing personalised dietary and lifestyle interventions. This research provides evidence for individualised approaches to optimise metabolic health through targeted ketone metabolism modulation, which could inform precision medicine strategies for MetS prevention and management.
The positive valence systems (PVS) domain, a key focus of the Research Domains Criteria framework, divides reward-related processes into three constructs: reward responsiveness, reward learning, and reward valuation. Difficulties with several of these reward constructs have been reported in people with mood-psychosis spectrum disorders. This study aims to examine how performance on tasks corresponding to these three constructs covaries, and how performance relates to mood and psychotic symptoms in adults with mood-psychosis spectrum disorders, those at familial risk, and controls.
Methods
Data from two studies (N = 278 and N = 332) were analyzed, which both included people with a psychotic disorder or bipolar disorder (patients), their first-degree relatives (FDRs), and controls. PVS constructs were measured using the Multi-Armed Bandit Task, Effort-Expenditure for Rewards Task, and Monetary Incentive Delay Task. Depression, mania, and psychosis symptoms were measured with self-report and interview instruments. Confirmatory factor analysis was used to examine covariation, and path analysis to test associations with symptoms.
Results
The three reward constructs showed weak (nonsignificant) covariance in all groups. There were a few impairments in reward-related performance in patients or FDRs, none that survived multiple-comparison correction. There were no associations between symptoms and performance on the PVS constructs after multiple comparisons correction.
Conclusions
The findings showed no evidence that performance on any of the three PVS constructs could constitute an endophenotype of mood-psychosis spectrum disorders. We recommend future research examining the contribution of specific cognitive skills to reward-related behavior, and to sources of heterogeneity in reward functioning within the patient group.
To compare long-term vestibular function in cochlear implant recipients with enlarged vestibular aqueduct and those without inner-ear malformations.
Methods
A comparative analysis was conducted on 53 cochlear implant recipients (27 with enlarged vestibular aqueduct, 26 with no inner-ear malformations). Vestibular function was assessed using caloric testing, vestibular-evoked myogenic potential, the video head impulse test and age-appropriate symptom questionnaires.
Results
Enlarged vestibular aqueduct patients demonstrated significantly better preservation of otolithic function post-implantation, with higher cervical vestibular-evoked myogenic potential response rates (56 vs 12 per cent, p = 0.001). Caloric testing showed similar vestibular dysfunction across both groups. Both cohorts exhibited significant asymmetry between implanted and non-implanted ears.
Conclusion
Cochlear implantation impairs vestibular function regardless of cochlear morphology, affecting both otolithic and low-frequency semicircular canal function. However, better saccular function preservation in enlarged vestibular aqueduct patients suggests unique vestibular adaptation, with implications for counselling and rehabilitation.
This pilot study describes the design and field evaluation of web-based pre-deployment medical screening and health monitoring by the Urban Search and Rescue (US&R) branch of the Federal Emergency Management Agency (FEMA).
Methods
A review of US&R medical officers’ (MOFR) and task force physicians’ workflow identified web-based solutions. A Microsoft Forms tool (Microsoft Corporation, Redmond, Washington, USA) was utilized for pre-deployment medical screening. A web-based dashboard was developed for reporting task force daily Injury and Illness Logs, submission tracking, and syndromic surveillance.
Results
The pre-deployment medical screening tool was completed by 100% of Incident Support Team (IST) members and took less than 4 minutes to complete. A post-deployment survey revealed that the new process was more efficient for the IST members and for the MOFRs in comparison to an in-person screen. Task force daily compliance with web-based Injury and Illness Log reporting was 84%. Successful syndromic surveillance was demonstrated and assisted in maintaining operational readiness. All tools were noted to be intuitive to use and were more efficient compared to prior workflows despite no advanced training in their use.
Conclusion
Web-based medical screening, reporting, and surveillance tools can be successfully implemented with high reporting adherence and improved workflow efficiency without prior training.
Firearm suicide among adolescents in the United States has increased in recent years, with Black and Latino youth experiencing disproportionately rising rates. Although firearm violence and mental health disparities have received growing attention, the structural conditions that shape racial inequities in firearm suicide risk remain insufficiently examined. This overview applies an intersectional and structural lens to analyze how systemic inequities including residential segregation, concentrated disadvantage, punitive school discipline practices, underinvestment in mental health infrastructure and commercial determinants of firearm availability contribute to differential suicide risk. Drawing on interdisciplinary literature and recent epidemiologic data, the manuscript maps the causal pathways through which structural racism and institutional inequities shape exposure to community violence, access to culturally responsive care, crisis response practices and household firearm environments. It further examines how these mechanisms interact with gender and lethal means availability to amplify disparities in suicide mortality. The analysis underscores the importance of multilevel, upstream interventions that address structural inequities, strengthen community-based supports and reduce access to lethal means. By reframing firearm suicide as a structurally patterned outcome rather than an individual-level phenomenon, this work advances a socio-ecological understanding of adolescent suicide prevention with implications for structural reform and suicide prevention policy.
Cognitive reserve (CR) is a protective factor in first-episode psychosis (FEP), influencing cognitive, clinical, and functional outcomes. CR is shaped by a combination of genetic, clinical, and environmental factors, yet the extent of their respective contributions remains unclear. This study investigates the influence of polygenic risk scores (PRS), clinical and environmental variables on CR in FEP.
Methods
A cohort of 174 individuals with non-affective FEP, aged 25.5 (SD=5.3), was analyzed. CR was assessed using a socio-behavioral proxy. PRS for educational attainment (PRSEA), intelligence (PRSIQ), cognitive performance (PRSCP), occupational attainment (PRSOA), physical activity (PRSPA), and schizophrenia (PRSSZ) were calculated. Age at onset, socioeconomic status, birth weight, and family history of psychosis were considered. Multiple regression models were employed to evaluate the impact of the different predictors on CR.
Results
PRSEA (p=0.002), age at onset (p=5.32x10-5), and family history of psychosis (p=0.001) emerged as the strongest contributors to CR. Higher PRSEA was associated with higher levels of CR, while earlier age at onset and positive family history were associated with lower CR. The model incorporating environmental, clinical, and genetic variables explained 17.7% of the variance in CR, and the one without PRS explained 13.5%. The inclusion of PRSEA in the model improved the explanatory power (Δadj.R2=0.042) and predictive accuracy (ΔRMSE=−0.288).
Conclusions
These findings highlight the role of precision psychiatry in better understanding CR. Early identification of individuals with earlier onset, family history of psychosis, and lower genetic predisposition to educational attainment may help characterize those with lower CR.
Balamuthia mandrillaris is a free-living amoeba that causes granulomatous amoebic encephalitis, a rare but frequently fatal infection of the central nervous system. In contrast to primary amoebic meningoencephalitis caused by Naegleria fowleri, B. mandrillaris infection is typically subacute to chronic and is commonly associated with haematogenous dissemination from extra-cranial sites. Here, we present a comparative analysis of the neuropathology of B. mandrillaris infection in humans and animals, highlighting conserved features of angiocentric invasion, granulomatous inflammation, necrotizing vasculitis and multifocal parenchymal injury. Across species, both trophozoites and cysts are consistently identified within affected tissue, reflecting sustained tissue persistence rather than explosive proliferation. Despite differences in disease kinetics and host immunity, the pathological signature of Balamuthia encephalitis is remarkably conserved. These findings validate the use of animal models for mechanistic investigation and therapeutic development and clarify key biological processes underlying this devastating disease.
The effects of maternal broccoli powder (BP) intake on inflammation and AMPK activation in weaning offspring programmed by maternal undernutrition remain poorly understood. This study aimed to investigate whether maternal BP intake during lactation ameliorates inflammation and affects AMPK phosphorylation in the hypothalamus and liver of weaning offspring subjected to maternal undernutrition. Pregnant rats received either a normal protein (NP, 20% casein) or a low protein (LP, 8% casein) diet. During lactation, dams were provided with either a normal protein diet without or with 0.74% BP (NP/NP or NP/NPBP) or a low protein diet without or with 0.74% BP (LP/LP or LP/LPBP). Blood, liver (left lateral lobular region), and hypothalamic samples (region estimated to include the arcuate nucleus and ventromedial hypothalamus) were collected on postnatal day 21. In the liver, macrophage count, NFκB p65 protein expression, and TNF-α mRNA expression were lower in LP/LPBP than in LP/LP. In the hypothalamus, Iba1 mRNA expression, NFκB p65 protein expression, and TNF-α mRNA expression were reduced in LP/LPBP compared to LP/LP. AMPK phosphorylation was upregulated in both the liver and hypothalamus of LP/LPBP offspring relative to LP/LP. In the liver, mTOR and Akt phosphorylation were downregulated in LP/LPBP compared to LP/LP. Additionally, Dnmt1 levels were lower in LP/LPBP than in LP/LP in the liver, whereas in the hypothalamus, Dnmt1 and Dnmt3a mRNA expression levels were higher in NP/NPBP than in NP/NP. In conclusion, maternal BP intake during lactation decreased inflammation and increased AMPK phosphorylation in the liver and hypothalamus of weaning rats programmed by maternal undernutrition.
Patients with Parkinson’s disease (PD) suffer from interrelated motor and non-motor symptoms. While most research focuses on motor improvement, this study investigated whether targeting mood via sequential bilateral dorsolateral prefrontal cortex (DLPFC) tDCS could favorably affect motor function in patients maintaining a stable medication ‘ON’ state. Additionally, we employed wearable smart devices to objectively evaluate real-world changes in daily activity and sleep patterns, complementing traditional clinician-rated scales.
Methods:
PD patients with mild-to-moderate depressive symptoms were enrolled. All participants completed a 7-day baseline monitoring period using a smart band. Participants received ten sessions of bilateral tDCS targeting the DLPFC (anode F3, cathode F4) at 2 mA for 30 minutes, three times a week. Clinical assessments and smart band monitoring were repeated during the final week of treatment. Pre–post changes and correlations were analyzed while controlling for potential confounders.
Results:
Following tDCS, it was significant improvements in K-MADRS, STAI, AS, UPDRS part III, and PDQ-39. Smart device data showed a significant increase in daily step counts after treatment, while changes in physical activity time and sleep duration were not significant. Changes in step count were strongly correlated with improvements in apathy, and this relationship remained significant after confounding variables (rho = –0.76, p < 0.001).
Conclusions:
Bilateral DLPFC tDCS significantly improved mood and motor function in patients with PD. Smart band data further showed an increase in daily step counts after the intervention, with reductions in apathy. These findings suggest that tDCS may enhance goal-directed behavior by modulating mood-related pathways, highlighting apathy as an important therapeutic target in PD.
An intrauterine device (IUD) is a highly effective long-acting and reversible contraceptive method widely available around the world and safe for nearly all women. However, very few women in Southwestern Ethiopia use.
Objectives:
To identify factors influencing an intention to use the intrauterine device among family planning users in Southwestern, Ethiopia.
Methods:
A facility-based cross-sectional study was conducted among 784 modern family planning users from 15th October to 15th November 2020. An interviewer-administered questionnaire was used. Estimates were generated using logistic regression model.
Results:
Thirty percent intended to use IUD. The most commonly cited reasons for their lack of an intention to use IUD were fear of side effects, lack of knowledge, and husband disapproval. Being able to read and write (AOR = 3.33 [95% C.I. 1.48, 7.49]) compared to those unable to read and write; Being rich (AOR = 1.69 [95% C.I. 1.02, 2.82]) compared to the poor; being knowledgeable about IUD (AOR = 2.74 [95% C.I. [1.67, 4.51]); having higher reproductive health autonomy (AOR = 1.53 [95% C.I. [1.09, 2.16]) were found to be significant factors influencing women’s intention to use an IUD.
Conclusion:
Nearly one-third of women who attend health facilities are currently using contraception reported an intention to use an IUD in the future. Public health interventions should focus on the cited reasons reaching all the community in need, and give priority for women who unable read and write, and lowest wealth status. Further interventional studies were recommended to determine effective interventions to increase women’s intention to use intrauterine device.
Inconsistent findings persist across resting-state functional imaging studies of regional brain alterations in postpartum depression (PPD), while connections to transcriptional profiles and neurotransmitter systems remain largely uncharacterized.
Methods
We performed a whole-brain voxel-wise meta-analysis of resting-state functional imaging studies comparing PPD patients and healthy controls using SDM-PSI software. JuSpace toolbox analyzed atlas-based nuclear imaging-derived neurotransmitter maps, and transcriptional data were sourced from the Allen Human Brain Atlas.
Results
Our systematic review identified 12 functional imaging studies (475 PPD patients, 504 controls). Patients with PPD displayed increased resting-state functional activity in the left inferior occipital gyrus and left precuneus as well as decreased resting-state functional activity in the right amygdala and left precentral gyrus. These functional alterations spatially overlapped with serotonergic, dopaminergic, and VAChT systems. Transcriptional analysis revealed PPD-related gene enrichments in ion channel function (transmembrane transport, gated/passive channels) and channel complexes.
Conclusions
The meta-analysis revealed functional alterations within the DMN, limbic, and primary sensorimotor systems in PPD patients. These changes were linked to neurotransmitter alterations and genetic modulations underlying brain dysfunction. Collectively, these findings advance mechanistic understanding of PPD pathophysiology.
Young migrants encounter heightened challenges as the intersection of their youth and migrant identities magnifies the influence of risk factors for suicide. Social media offers a platform for young migrants to express emotions, seek support and connect with others, often anonymously. However, how they communicate about self-harm and suicide online remains underexplored. This qualitative study involved 17 online interviews with young migrants aged 15–25 years. Transcribed data were coded and thematically explored using Braun and Clarke’s reflexive thematic analysis methodology. Four key themes were identified: (1) Exposed and isolated: The emotional toll of viewing self-harm and suicide-related content on young migrants; (2) Connected but at-risk: The dual role of social media in migrant belonging; (3) Digital belonging across borders: Benefits and strains of staying connected; and (4) Helpful and harmful: The dual nature of support on social media. Social media has a complex impact on young migrants, offering both protective and harmful effects. While exposure to distressing or discriminatory content may exacerbate feelings of isolation and disconnection, social media can also promote belonging, cultural understanding and resilience. It also provides accessible support, though poor-quality advice and stigma may deter help-seeking. These insights can inform culturally responsive mental health interventions.
We used a large language model integrated in the electronic health record to evaluate unnecessary central lines. It had a 16% sensitivity and 99% specificity for detecting unnecessary lines. Although it missed many unnecessary lines, the high specificity suggests potential as a tool where human review is not feasible.
