ABSTRACT

Incarceration is associated with adverse physical and mental health that are often brought to light during reentry into the community, particularly in the immediate period following release. Social support, specifically from family members, has been identified as a key protective factor that may promote health and reintegration success among formerly incarcerated individuals. However, less is known about how specific types of family support-emotional and instrumental-relate to health outcomes following release from incarceration. The current study uses data from 517 individuals incarcerated in a large Texas prison, surveyed before and approximately one month after release, to examine the relationship between family support and self-rated physical and mental health. Logistic regression models revealed that strong emotional family support was significantly associated with better self-rated physical health and mental health one month post-release. Additionally, strong instrumental family support predicted better mental health but not physical health among respondents. These findings highlight the crucial role of emotional and instrumental familial support systems in fostering and reducing health disparities and promoting equity among justice-impacted populations.

ABSTRACT

Groundwater quality in Kadaladi is a critical concern due to contamination from natural and human activities. This study assesses heavy metal concentrations across pre-monsoon and post-monsoon seasons at 44 sampling sites, using the Heavy Metal Pollution Index (HPI), Metal Index (MI), and non-carcinogenic risk (HQ) assessments. Key heavy metals analysed include Cu, Pb, Zn, Ni, Cd, Mn, and Fe, in Pre-monsoon and Post-monsoon with comparisons to WHO (2017) standards using atomic absorption spectrometry. The Heavy Metal Pollution Index (HPI) and Metal Index (MI) were computed to assess contamination levels, and health risks were evaluated through non-carcinogenic hazard quotient (HQ) models for adults and children. Results revealed that Mn and Fe concentrations exceeded WHO permissible limits in 20% of the samples, with Site 33 showing the highest pollution in HPI (99.1) and MI (17.89). Post-monsoon samples showed notably higher contamination, attributed to monsoonal leaching and runoff from agricultural and saltpan activities. GIS-based spatial analysis identified persistent hotspots at Sites 6, 24, and 33. Children were particularly vulnerable, with HQ values exceeding 2.0 in affected zones, especially due to Mn exposure. HQ values indicated that children face higher health risks, particularly from Mn, exceeding permissible limits in 4.55% of samples. Pearson correlation revealed strong Mn-Fe geogenic associations, while Cd-Mn correlations post-monsoon pointed to anthropogenic sources. The integration of spatial mapping using GIS and statistical methods provides insight into contamination hotspots, emphasizing the critical role of monsoonal hydrology in mobilizing pollutants. These findings underscore the need for region-specific mitigation strategies and regular water quality monitoring. The study fills a regional knowledge gap and contributes globally relevant insights on managing groundwater quality in vulnerable coastal systems.

ABSTRACT

PURPOSE: This study aims to compare the clinical course of COVID-19 in pregnant versus non-pregnant women aged 15-45 in Tabriz, focusing on disease severity, mortality, and pregnancy outcomes.

METHODS: A total of 300 women were analyzed, with 150 pregnant and 150 non-pregnant participants. Data collected included demographic information, comorbidities, clinical outcomes, and pregnancy-related complications.

RESULTS: The mean age of pregnant women was 32 years, while non-pregnant women averaged 38 years. Common comorbidities in the pregnant group included gestational diabetes and hypertension. Pregnant women predominantly experienced mild COVID-19 cases, whereas severe cases were more frequent in non-pregnant women; however, these differences were not statistically significant. Both groups had a mortality rate of 4.7%, with seven deaths reported in each cohort. Among pregnant women, 19% experienced preterm births, 6.7% had miscarriages, 3.5% had stillbirths, and 6.7% faced postpartum hemorrhages, with most preterm births being induced.

CONCLUSIONS: The findings suggest that pregnancy does not worsen the clinical course of COVID-19, as pregnant women generally exhibit milder symptoms and require fewer intensive care unit admissions compared to their non-pregnant counterparts.

ABSTRACT

BACKGROUND: Secondary epiretinal membranes (sERM) are common in uveitis and often associated with cystoid macular edema (CME), which increases the need for anti-inflammatory treatment. While surgical removal can improve anatomical and visual outcomes, its effect on intraocular inflammation and steroid requirement remains unclear. This study evaluates whether vitrectomy with ERM peeling can reduce the need for postoperative steroid therapy in uveitic eyes.

METHODS: This retrospective single-center study reviewed 67 eyes of 67 patients with history of uveitis who underwent sERM peeling between 11/2002 and 04/2023. Demographic data, uveitis classification (SUN), spectral domain optical coherence tomography (SD-OCT) findings, and pre-/postoperative steroid requirements were analyzed. Statistical significance testing was performed using a paired two-tailed t-test.

RESULTS: Of the 67 eyes, 50.7% were right eyes, and 65.7% of patients were female. Mean age at timepoint of surgery was 63.1 ± 13.6 years, with 53.7% phakic eyes. Uveitis was classified as anterior (17.9%), intermediate (44.8%), posterior (31.3%), and panuveitis (6.0%). Steroid therapy was reduced in 28.4% of patients, remained unchanged in 56.7%, and increased in 14.9%. Preoperatively, cystoid macular edema (CME) was present in 41.4% of the 58 available SD-OCT scans. Postoperatively, retinal thickness, macular volume, and total retinal volume decreased significantly (p < 0.001). Postoperative CME was found in 31.3% in first postoperative SD-OCT and was newly observed in 6.0%, while 62.7% showed no CME.

CONCLUSIONS: ERM peeling in uveitic eyes does not guarantee functional improvement or a consistent reduction in steroid dependency. While approximately one-third of patients benefited from reduced steroid use-particularly those with preoperative CME-the majority showed no change, and a subset required intensified therapy due to postoperative inflammation or CME recurrence. Careful patient selection remains essential.

ABSTRACT

BACKGROUND: Error-corrected next-generation sequencing (ecNGS) enables the sensitive detection of chemically induced mutations. Matsumura et al. reported Hawk-Seq™, an ecNGS method, demonstrating its utility in clarifying mutagenicity both qualitatively and quantitatively. To further promote the adoption of ecNGS-based assays, it is important to evaluate their inter-laboratory transferability and reproducibility. Therefore, we evaluated the inter-laboratory reproducibility of Hawk-Seq™ and its concordance with the transgenic rodent mutation (TGR) assay.

RESULTS: The Hawk-Seq™ protocol was successfully transferred from the developer’s laboratory (lab A) to two additional laboratories (labs B, C). Whole genomic mutations were analyzed independently using the same genomic DNA samples from the livers of gpt delta mice exposed to benzo[a]pyrene (BP), N-ethyl-N-nitrosourea (ENU), and N-methyl-N-nitrosourea (MNU). In all laboratories, clear dose-dependent increases in base substitution (BS) frequencies were observed, specific to each mutagen (e.g. G:C to T:A for BP). Statistically significant increases in overall mutation frequencies (OMFs) were identified at the same doses across all laboratories, suggesting high reproducibility in mutagenicity assessment. The correlation coefficient (r²) of the six types of BS frequencies exceeded 0.97 among the three laboratories for BP- or ENU-exposed samples. Thus, Hawk-Seq™ provides qualitatively and quantitatively reproducible results across laboratories. The OMFs in the Hawk-Seq™ analysis positively correlated (r² = 0.64) with gpt mutant frequencies (MFs). The fold induction of OMFs in the Hawk-Seq™ analysis of ENU- and MNU-exposed samples was at least 14.2 and 4.5, respectively, compared to 6.1 and 2.5 for gpt MFs. Meanwhile, the fold induction of OMFs in BP-exposed samples was ≤ 4.6, compared to 8.2 for gpt MFs. These observations suggest that Hawk-Seq™ demonstrates good concordance with the transgenic rodent (TGR) gene mutation assay, whereas the induction of mutation frequency by each mutagen might not directly correspond.

CONCLUSIONS: Hawk-Seq™-based whole-genome mutagenicity evaluation demonstrated high inter-laboratory reproducibility and concordance with gpt assay results. Our results contribute to the growing evidence that ecNGS assays provide a suitable, or improved, alternative to the TGR assay.

ABSTRACT

INTRODUCTION: With the growing reliance on digital platforms in education, nursing students face increasing exposure to screen time and academic pressures. Despite existing research, region-specific studies on how digital burnout predicts psychological health in UAE nursing students are limited.

AIM: The study aimed to assess the correlation between digital burnout and nursing students’ general psychological health and identify variables that predict both.

METHODS: This study employed quantitative methods, utilizing correlational and descriptive approaches. The study was conducted during the 2024-2025 academic year and involved a sample of 140 nursing students. Statistical testing encompassed descriptive statistics, correlation analyses, and multiple regression analysis.

RESULTS: The level of digital burnout was high, and general psychological health was moderate. The correlation analysis revealed a positive and significant correlation between students’ overall digital burnout scale scores and overall health scores (r = 0.71, p < 0.001). A multivariate regression study identified significant determinants of digital burnout and general psychological health among students. Younger students, those enrolled in over five classes, and nursing students exhibited elevated symptoms of digital burnout. Conversely, the academic level showed no substantial impact. Additionally, digital burnout was a major predictor of poor general psychological health, but other demographic and academic variables were not substantial.

CONCLUSION: This study demonstrates that digital burnout, primarily induced by academic pressures, considerably affects the mental and physical well-being of nursing students. Specific institutional strategies such as fostering digital well-being, modifying course loads, and augmenting mental health support are crucial for safeguarding student wellness and cultivating resilient future nursing professionals.

ABSTRACT

BACKGROUND: Work engagement and burnout are two of the most significant work states in nurses. The increasing prevalence of information and communication technologies (ICT) in the workplace means that nurses are required not only to actively embrace technological advancements for their own well-being and to enhance the quality of nursing care, but also to simultaneously learn to cope with the mental and physical health issues arising from ICT use. Nevertheless, research on the work status of Chinese nurses in the context of ICT demands remains scant, particularly in large-sample, multi-center empirical studies.

AIM: to investigate the distinct predictors of work engagement and job burnout among Chinese nurses in the context of ICT demands, and to clarify the differential mechanisms underlying these two work states.

METHODS: A cross-sectional survey (N = 1612) was conducted among Chinese nurses from January to February 2024, utilizing questionnaires to collect demographic information, work-related details, job resources, job stressors, work engagement and job burnout within the context of ICT usage. Descriptive statistics and one-way ANOVA were employed to identify control variables based on demographic and work-related information. Pearson correlation analysis explored relationships between job resources, job stressors, and nurses’ work status. Regression models for work engagement and job burnout were constructed, with LASSO regression selecting the most critical influencing variables.

RESULTS: The LASSO regression model of nurses’ work engagement includes seven explanatory variables, of which the ones that pass the significance test are harmonious work passion, positive affect, and self-efficacy. The LASSO regression model of nurses’ job burnout included 9 variables, of which the statistically significant ones were ego depletion, negative affect, job insecurity, and ICT demands.

CONCLUSIONS: This study makes three innovative contributions. First, it identified three key resource gain factors that significantly related to nurses’ work engagement. Second, it pinpointed four principal resource loss factors that contribute to nurses’ burnout. Third, it distinguished between the two concepts of work engagement and burnout and examined the differentiated factors that influence them, thereby providing a nuanced understanding of the distinct mechanisms at play.

ABSTRACT

BACKGROUND AND PURPOSE: To test whether the enhanced 3D-NEVERview (3D-NEVERview + C) sequence improves delineation accuracy and allows clinically meaningful dose reductions to the brachial plexus of nasopharyngeal carcinoma (NPC) with cervical lymph node metastasis in radiotherapy during MRI simulation.

MATERIALS AND METHODS: Fifty NPC patients with cervical lymph node metastasis were enrolled. The contrast-to-noise ratio (CNR), signal-to-noise ratio (SNR), and contrast ratio (CR) of brachial plexus were compared between two different sequences. The volumes of brachial plexus delineated automatically (V_auto-L, V_auto-R) and manually (V_BP-L, V_BP-R) were performed statistical comparisons. Radiotherapy plans were categorized into original plans (without dose constraints on the brachial plexus) and optimized plans (with dose constraints). The volumes receiving 60 Gy (V₆₀) and 66 Gy (V₆₆), maximum dose (D_max) and mean dose (D_mean) to brachial plexus were analyzed statistically.

RESULTS: CNR, SNR, and CR between two sequences showed statistical significance (P < 0.05). The volumes of V_auto-L, V_auto-R, V_BP-L and V_BP-R were (2.38 ± 0.78) cm³, (2.40 ± 0.87) cm³, (27.07 ± 5.32) cm³ and (27.00 ± 5.74) cm³, respectively, with significant differences (P < 0.001). The V₆₀ and V₆₆, D_max and D_mean of brachial plexus also differed significantly between the original and optimized plans (P < 0.05).

CONCLUSION: The 3D-NEVERview + C sequence significantly enhances the CR, thereby providing a clearer location of brachial plexus. In NPC patients with cervical lymph node metastasis, excessive doses to brachial plexus frequently occurred. Protecting brachial plexus during radiotherapy is crucial for reducing the risk of nerve injury. Therefore, incorporating the 3D-NEVERview + C sequence in MRI-sim is highly recommended.

ABSTRACT

BACKGROUND: Emergency department (ED) and intensive care units (ICUs) are areas where triage is frequently applied. This study was conducted to evaluate the triage decision-making levels and affective factors of nurses working in adult cardiovascular ED and ICUs.

METHODS: This is a cross-sectional study conducted in a tertiary cardiovascular healthcare center. The triage decision-making levels of nurses were assessed by the “Triage Decision Making Inventory (TDMI)”.

RESULTS: The mean age of the nurses (n = 110) was determined as 28.39 ± 4.71 years, the duration of working in ED/ICUs was determined as 45.47 ± 29.17 months and the duration of professional experience was determined as 65.35 ± 48.46 months. The majority of the nurses in the study were female (77.3%), single (61.8%), bachelor’s degree graduates (76.4%) and night – day shift workers (76.4%). The mean TDMI total score of the nurses was determined as 171.12 ± 21.02. A statistically significant association was found between the nurses’ age, duration of professional experience, gender, working type, receiving triage training after graduation and considering themselves competent in triage and their triage decision-making levels (p < 0.05).

CONCLUSION: It was determined that the triage decision-making levels of nurses working in adult cardiovascular ED and ICUs were high, but the majority of them did not consider themselves competent in triage. According to the results of this study, it is recommended that triage training of nurses be supported by institutions and triage roadmaps be created in clinics.

ABSTRACT

BACKGROUND: Sleep deprivation and overload have been associated with increased risks of both depression and mortality. However, no study has quantitatively compared the effects of objective and subjective sleep duration on mortality or examined the mediating role of depressive symptoms in these associations.

METHODS: Utilizing data from the NHANES 2011-2014, this study employed structural equation modeling (SEM) to explore the impact of depressive symptoms, measured by Patient Health Questionnaire (PHQ-9) scores, on the relationship between both objective and subjective sleep durations and all-cause mortality.

RESULTS: The study included 7838 participants, comprising 4392 women (55.96%) with a mean age of 46.51 (0.46) years. Over a median 6.83-year follow-up, 582 deaths occurred. The restricted cubic spline curves demonstrated a J-shaped relationship between objective sleep duration and the all-cause mortality risk, and a U-shaped relationship between subjective sleep duration and the all-cause mortality risk. SEM analysis revealed that when subjective sleep duration was < 7 h/day, the indirect effect of sleep duration on all-cause mortality was – 0.013 (P = 0.003), and the mediation proportion of PHQ-9 scores was 40.63%. When objective sleep duration ≥ 7 h/day, the indirect effect of sleep duration on all-cause mortality was 0.003 (P = 0.028), and the mediation proportion of PHQ-9 scores was 2.10%.

CONCLUSIONS: The study confirmed a J-shaped and a U-shaped correlation for objective and subjective sleep duration with mortality risk. Depressive symptoms significantly mediated the association between shorter subjective sleep duration and mortality. This suggests that there is a need to focus on the co-morbidity of subjective sleep deprivation and depression.
