Objective This cross-sectional study (1) compared social support, psychological-capital dimensions, and both C-MLQ dimensions between students with and without visual impairments; and (2) among students with visual impairments, examined the association between social support and presence of meaning (C-MLQ-P) and tested the a priori hypothesized cross-sectional indirect association through hope. Self-efficacy, resilience, and optimism were examined exploratorily in descriptive/correlational and hierarchical-regression analyses. Methods Participants were 170 students with visual impairments and 294 students without visual impairments from a vocational college in China. They completed measures of social support, psychological capital, and meaning in life. Group differences were examined using MANCOVA with follow-up ANCOVAs. Among students with visual impairments, Pearson correlations and an exploratory hierarchical regression were conducted, and H3 was tested using a single cross-sectional indirect-effect model with social support (ASSS-Total) as the predictor, hope (PPQ-Hop) as the indirect variable, presence of meaning (C-MLQ-P) as the outcome, and age and sex as covariates. Results After adjustment for age and sex, students with visual impairments scored significantly lower on objective support, support utilization, self-efficacy, optimism, presence of meaning, and search for meaning than students without visual impairments, whereas no significant group differences were observed for subjective support, resilience, or hope. Among students with visual impairments, social support was positively associated with the presence of meaning (r = 0.56, p < 0.01). In the H3 model, the total association between social support and presence of meaning was 0.8912 (95% CI [0.6988, 1.0835]), the direct association was 0.3560 (95% CI [0.1655, 0.5465]), and the indirect association through hope was 0.5352 (BootSE = 0.0923, 95% bootstrap CI [0.3680, 0.7239]). Conclusions In this sample from a single Chinese vocational college, social support was positively associated with the presence of meaning, and a significant cross-sectional statistical indirect association was observed through hope. Because the data were cross-sectional, the observed indirect association does not establish temporal ordering or a causal mechanism. Longitudinal and experimental studies are needed to determine whether changes in social support precede changes in hope and presence of meaning.

BACKGROUND: Israel's 2015 mental health reform transferred responsibility for mental health services from the government to community health maintenance organisations (HMOs), aiming to improve accessibility and equity and reduce stigma. However, its implications for different populations remain significantly underresearched. AIMS: To examine trends in mental health service utilisation and psychiatric medication issue rates among Arab and Ultra-Orthodox Jewish populations before and after the 2015 mental health reform. METHOD: = 2 847 184). Participants were classified as either general (non-Ultra-Orthodox Jewish), Ultra-Orthodox Jewish or Arab. The study analysed annual community visits to mental health professionals and dispensed psychiatric prescriptions. RESULTS: Between 2012 and 2019 the number of mental health service users increased across all populations, most prominently among Ultra-Orthodox Jewish and Arab populations (1.94- and 1.91-fold, respectively), compared with 1.55-fold in the general population. Annual community visits increased 2.4-fold in the general population, 2.2-fold in the Ultra-Orthodox Jewish population and 3.7-fold among Arabs, who had the lowest baseline utilisation. Psychiatric medication issue rates increased most in the Ultra-Orthodox Jewish population (2.5-fold), compared with 1.7-fold in the Arab and 1.5-fold in the general population. Women consistently used more services than men, with the greatest relative increase among Arab women. CONCLUSIONS: The findings suggest improved access to mental health services over the study period spanning the 2015 mental health reform, particularly in previously underserved populations. Continued progress requires culturally sensitive, community-tailored interventions for Arab and Ultra-Orthodox Jewish populations.

This study evaluated the reliability and validity of a context-aware sleep holistic cycle gate algorithm and explored its potential for artificial intelligence (AI)-based personalized sleep management in digital health-care. A 6-week prospective observational study was conducted in 25 adults aged 20–65 years. Participants recorded daytime activities, eve-ning behaviors, presleep environmental factors, sleep outcomes, and feedback adherence using a mobile application. Five sleep-related indices were calculated, and a context-aware gate algorithm comprising five domains was applied. Reliability was assessed through internal consistency and reproducibility analyses, while validity was examined using correlations with sleep quality indicators and receiver operating characteristic curve analyses. Data completion and adherence rates were 80.3%±9.8% and 72.7%±11.6%, respectively. The sleep readiness index was positively correlated with subjective sleep quality (r=0.53, P<0.01). The algorithm demonstrated moderate predictive performance (area under the curve=0.73), with the environment and presleep gates showing the highest accuracy. Following personalized feedback, sleep onset latency decreased by 12.6%, and perceived sleep quality improved significantly (P<0.05). In conclusions, the context-aware sleep holistic cycle gate algorithm demonstrated acceptable reliability and validity for predicting sleep quality. These findings suggest that the proposed framework may serve as a foundational platform for the development of AI-driven personalized sleep management systems and future digital healthcare applications related to sleep rehabilitation and health promotion.

Purpose: The present study aimed to examine the associations between anthropometric indexes derived from body measurements and body satisfaction.Methods: The study included voluntary female aged 19–64 years. The face-to-face questionnaire included questions on participants’ sociodemographic characteristics (age, sex, educational level, marital status, employment status, and socioeconomic status), the Body Image Scale (BIS), and the Body Appreciation Scale (BAS). Anthropometric measurements were obtained by trained researchers in accordance with standardized procedures. Using measurements, anthropometric ratios and indices—waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), body mass index (BMI), conicity index (CI), body shape index (BSI), abdominal volume index (AVI), and body adiposity index (BAI)—were calculated. Data were analyzed using SPSS 23.0.Results: A total of 1.291 female participated in the study, with a mean age of 36.8 ± 12.7 years. Scale scores varied significantly across participants’ sociodemographic characteristics (p

Few events in recent history have forced clinicians and researchers to rethink mental health quite like COVID-19. In this commentary, we reflect on something that struck us while reading the work of Cantone et al. : the pandemic, for all its devastation, created a kind of unplanned observational window, a chance to study, at population scale, what happens when stress and rhythm disruption hit at the same time. Healthcare Workers (HCWs) were at the epicentre of this. They didn't just witness the crisis; they absorbed it, shift after shift, for months. What the data show is that their depressive symptoms and rhythm instability were not random; they appear systematically linked, and at levels one would more typically associate with mood disorder research. We discuss these findings through the lens of DYMERS (Dysregulation of Mood, Energy, and Social Rhythms Syndrome), a heuristic transdiagnostic construct that, in our view, captures something that standard categorical diagnoses tend to miss: the subthreshold, fluctuating psychopathology that sits just below the threshold of formal diagnosis but causes real impairment. The pandemic may not have created these vulnerabilities, but it may well have sharpened our ability to see them.

OBJECTIVE: The combination of action observation and motor imagery (AO+MI) has emerged as a promising neurorehabilitation strategy to promote sensorimotor plasticity without real movement, making it particularly valuable for individuals whose motor capacity is limited or absent. Improving AO+MI protocols requires understanding whether different observation stimuli engage the sensorimotor system to varying degrees, as the quality of cortical activation during each training trial may directly influence cumulative neuroplastic outcomes. The present study aimed to determine how the observation modality influences the activation of the sensorimotor cortex during synchronous AO+MI. APPROACH: Here, we investigated the effects of three observation modalities: immersive virtual reality (iVR), two-dimensional video and real-world observation of a robotic agent, on sensorimotor cortical engagement, using Event-Related Desynchronization (ERD) as a neurophysiological marker. Electroencephalographic (EEG) signals were recorded from fifteen healthy participants across three sessions, one per modality, while they observed a humanoid robot performing arm elevation movements and simultaneously engaged in motor imagery of the same movements. ERD was computed for alpha and beta frequency bands over eight electrodes covering frontocentral, central, and centroparietal regions. MAIN RESULTS: Statistical analyses revealed significant modality-dependent differences in sensorimotor cortical engagement across multiple frequency bands, electrode locations, and movement types. Immersive virtual reality consistently elicited the strongest desynchronization, with robust effects in the beta band over frontocentral and right centroparietal regions, and in the alpha band over the right central motor cortex. SIGNIFICANCE: These results demonstrate that the modality of action observation significantly shapes sensorimotor cortical engagement during AO+MI. Our findings also support the integration of immersive virtual reality as a neurophysiological grounded tool for optimizing AO+MI-based neurorehabilitation protocols and brain-computer interface applications.

هدف: ترکیب مشاهده عمل و تصویرسازی حرکتی (AO+MI) به‌عنوان یک راهبرد نویدبخش در نوروهیبیلیتیشن برای ارتقای پلاستیسیتی حسی‌حرکتی بدون حرکت واقعی مطرح شده است و به‌ویژه برای افرادی که ظرفیت حرکتی آن‌ها محدود یا غایب است، ارزشمند می‌باشد. بهبود پروتکل‌های AO+MI مستلزم درک این موضوع است که آیا محرک‌های مشاهده‌ای مختلف، سیستم حسی‌حرکتی را به درجات متفاوتی درگیر می‌کنند یا خیر، چرا که کیفیت فعال‌سازی قشری در هر نوبت تمرین ممکن است به‌طور مستقیم بر پیامدهای تجمعی نورولاستیک تأثیر بگذارد. مطالعه حاضر با هدف تعیین چگونگی تأثیر شیوه مشاهده بر فعال‌سازی قشر حسی‌حرکتی در حین AO+MI همزمان انجام شد. روش: در این پژوهش، اثرات سه شیوه مشاهده شامل واقعیت مجازی فراگیر (iVR)، ویدئوی دوبعدی و مشاهده دنیای واقعی یک عامل رباتیک بر درگیری قشری حسی‌حرکتی با استفاده از شاخص غیربسامدسازی وابسته به رویداد (ERD) به‌عنوان نشانگر نوروفیزیولوژیک بررسی شد. سیگنال‌های الکتروانسفالوگرافی (EEG) از پانزده شرکت‌کننده سالم در سه جلسه (هر جلسه یک شیوه) ثبت شد، در حالی که آن‌ها حرکات بالا بردن بازوی یک ربات انسان‌نما را مشاهده می‌کردند و به‌طور همزمان به تصویرسازی حرکتی همان حرکات می‌پرداختند. ERD برای باندهای فرکانسی آلفا و بتا بر روی هشت الکترود پوشش‌دهنده نواحی فرونتو‌سنتـرال، سنتـرال و سنتروپریتال محاسبه شد. نتایج اصلی: تحلیل‌های آماری تفاوت‌های معنادار وابسته به شیوه مشاهده را در درگیری قشری حسی‌حرکتی در چندین باند فرکانسی، محل الکترود و نوع حرکت نشان داد. واقعیت مجازی فراگیر به‌طور پیوسته قوی‌ترین غیربسامدسازی را ایجاد کرد، با اثرات بارز در باند بتا بر نواحی فرونتو‌سنتـرال و سنتروپریتال راست، و در باند آلفا بر قشر حرکتی مرکزی راست. اهمیت: این نتایج نشان می‌دهد که شیوه مشاهده عمل به‌طور معناداری الگوی درگیری قشری حسی‌حرکتی را در حین AO+MI شکل می‌دهد. یافته‌های ما همچنین از ادغام واقعیت مجازی فراگیر به‌عنوان ابزاری مبتنی بر شواهد نوروفیزیولوژیک برای بهینه‌سازی پروتکل‌های نوروهیبیلیتیشن مبتنی بر AO+MI و کاربردهای رابط مغز و رایانه حمایت می‌کند.
