Perceived neighborhood danger poses significant risks to mental health in later life, yet the underlying psychological mechanisms remain unclear. Given that environmental stressors can compromise sleep health, we conceptualize insomnia symptoms as a potential mediator in the association between perceived neighborhood danger and depressive symptoms. Data from 2,240 adults aged 65 or older from Wave 3 of the National Social Life, Health, and Aging Project (NSHAP) were analyzed. Multivariate analyses showed significant associations of both perceived neighborhood danger and insomnia symptoms with depressive symptoms after controlling for sociodemographic and health covariates. Bootstrap mediation analysis provided supportive evidence for the indirect effect of perceived neighborhood danger on depressive symptoms through insomnia symptoms (B = .04, SE = .01, bias-corrected 95% CI = [.02, .07]), accounting for 25.8% of the total effect. Insomnia symptoms were identified as an important pathway through which perceived neighborhood danger undermines mental health in older adults.by Yong Jae Lee, Nam Kyeong Kim, Kidong Kim, Chel Hun Choi, Keun Ho Lee, Jong-Min Lee, Kwang Beom Lee, Dong Hoon Suh, Sunghoon Kim, Min Kyu Kim, Seok Ju Seong, Myong Cheol Lim
ObjectiveTo identify the effect of fascial closure using barbed sutures on the incidence of incisional hernia in patients undergoing elective midline laparotomy for gynecological diseases.
MethodsIn this multicenter, non-blind randomized controlled trial conducted from February to December 2021, patients with a BMI 2 and aged >18 years, scheduled for midline laparotomy, were randomly assigned to receive either barbed (experimental) or non-barbed sutures (control) for fascial closure. The primary outcome was the cumulative incidence rate of incisional hernia up to 1-year post-surgery. Secondary outcomes included incisional hernia up to 2-years post-surgery, wound complications, and postoperative pain assessed by Brief Pain Inventory-Korean scores, and Numeric Rating Scale.
ResultsOut of 174 patients (experimental, 86; control, 88), 36 were excluded due to dropout or loss to follow-up, leaving 138 patients (experimental, 67; control, 71) included in the analysis. The groups were balanced in terms of cancer surgeries, mean wound length, and mean surgery time. The cumulative incidence rates of incisional hernia up to 1-year (0.0% vs. 1.4%; p > 0.999) and 2-years (0.0% vs. 3.4%, p = 0.496) post-surgery did not differ significantly between the experimental and control groups. Additionally, no significant differences were observed in the incidence of wound dehiscence 4 weeks post-surgery, cumulative incidences of wound dehiscence and wound infection up to 4 weeks post-surgery, or postoperative pain scores between the groups.
ConclusionsFascial closure using barbed sutures resulted in no cases of incisional hernia up to 2-years post-surgery, but did not demonstrate a significant reduction in incisional hernia rates compared with the non-barbed suture.

BackgroundRadiotherapy for locally advanced esophageal cancer can induce lymphopenia, potentially worsening outcomes. This study examines the association between clinical outcomes and the effective dose to the immune cells (EDIC), a measure of lymphocyte radiation exposure.
MethodsWe retrospectively analyzed 107 patients with locally advanced esophageal squamous cell carcinoma treated with definitive concurrent chemoradiotherapy (CCRT). The EDIC was calculated based on the mean lung dose, mean heart dose, and integral total body dose using established models. Patients were stratified into high (n = 42) and low (n = 65) effective dose to the immune cells (EDIC) groups using a cut-off value of 4.28 Gy. Survival outcomes, including overall survival (OS), progression-free survival (PFS), locoregional failure-free survival (LRFS), and distant metastasis-free survival (DMFS), were assessed.
ResultsThe 5-year OS and PFS rates were significantly lower in the high EDIC group than in the low EDIC group (51.9% vs. 66.6%, p = 0.043; 20.8% vs. 31.8%, p = 0.002, respectively). Multivariate analysis identified high EDIC as an independent predictor of poorer OS (hazard ratio (HR): 2.06, 95% confidence interval (CI): 1.1–3.86, p = 0.024) and PFS (HR: 1.7, 95% CI: 1.04–2.78, p = 0.034). Similarly, the 5-year LRFS and DMFS rates were significantly lower in the high EDIC group than in the low EDIC group (24.1% vs. 34.9%, p = 0.003; 29.0% vs. 44.0%, p = 0.018, respectively).
ConclusionA higher EDIC is an independent predictor of poor survival in patients with esophageal squamous cell carcinoma undergoing CCRT. Reducing radiation exposure to the immune system through optimized radiation planning and lymphocyte-sparing techniques may improve patient outcomes.

Quick-soluble gelatin microparticles (QS-GMP) are emerging embolic agents under investigation for temporary vascular occlusion, offering reduced ischemic risk compared to permanent materials. The aim of this preclinical study was to evaluate the safety and efficacy of QS-GMP for transarterial embolization in a rabbit model of urinary bladder embolization. Twelve male New Zealand White rabbits underwent bilateral umbilical artery embolization using QS-GMP. Animals were assigned to four time-points (immediately, 3, 7, and 14 days post-embolization), with comprehensive assessments including clinical observations, hematologic and serum biochemical analysis, angiography, and histopathology. The procedure was technically feasible in all animals without intraoperative complications. Temporary hematuria and a transient decrease in body weight were observed post-procedure, both of which resolved spontaneously. Complete occlusion of the cranial vesical artery and absence of bladder wall perfusion were achieved immediately after embolization, followed by full recanalization at 3 days. Angiographic imaging at 7 and 14 days revealed transient hypervascularization of the bladder wall. Histopathological analysis showed marked edema, epithelial necrosis, and inflammatory infiltration at 3 and 7 days, with full urothelial regeneration observed at 14 days. No signs of ureteral or renal injury, or adverse systemic responses were detected. These findings suggest that QS-GMP may serve as a feasible option for temporary arterial occlusion in future veterinary lower urinary tract applications, although further long-term evaluation is warranted.by Sugy Choi, Elizabeth Knopf, Megan A.

BackgroundPregnant and parenting women with substance use disorders (SUDs) face complex and overlapping challenges, including substance use, legal issues, housing instability, and trauma. Effective interorganizational collaboration is critical but often hindered by fragmented care and resource limitations. This study explores the key barriers and facilitators that impact collaborative efforts among healthcare providers, government agencies, and community organizations in addressing SUD among pregnant and parenting women.
MethodsThis qualitative study was conducted in New York State between April 2022 and April 2023. The study focused on organizations that provide services to pregnant and parenting women with SUDs, including government agencies, SUD treatment centers, healthcare settings, and community-based care organizations. Semi-structured, one-on-one interviews were conducted with staff to explore how their organizations coordinate care. Thematic analysis was used to identify patterns related to interorganizational collaboration. Primary data were collected through interviews with 30 staff members across multiple stakeholder groups: child welfare services (n = 8), criminal legal agencies (n = 5), health agencies (n = 3), healthcare service settings (n = 4), SUD treatment programs (n = 6), and community-based organizations (n = 4). Interviews lasted approximately one hour and focused on organizational roles, referral processes, and coordination efforts in serving the target population.
ResultsCollaborative care was primarily facilitated through referral networks, case management teams, and the presence of embedded healthcare professionals. However, these systems were frequently limited by fragmented communication, stigmatizing attitudes, and insufficient resources. Organizational facilitators included co-located healthcare staff within child welfare services and formalized partnerships across sectors. Key barriers included staffing shortages, burnout, and misalignment of organizational goals. At the individual level, collaboration often depended on informal relationships and staff-driven initiatives, though interdisciplinary knowledge gaps remained a significant challenge.
ConclusionsImproving service coordination for pregnant and parenting women with SUDs will require stronger organizational infrastructure, investment in cross-sector communication strategies, and deliberate efforts to address stigma. Future research should explore models that support sustained, formalized interagency partnerships to enhance care integration.
