Objectives: This study aimed to investigate the prevalence of depressive symptoms among hospital nurses and their associations with psychosocial and job-related factors. Methods: A total of 515 nurses at one university hospital participated in this study. Data on demographics, job-related factors, burnout, social conflict, happiness, and ego-resiliency were collected using self-reported questionnaires. Depressive symptoms were assessed using the depressive subscale of the Hospital Anxiety and Depression Scale, with scores of 8 or higher indicating their presence. Demographics, job-related, and psychosocial factors were compared based on the presence of depressive symptoms. Logistic regression analysis was conducted to identify factors associated with depressive symptoms. In addition, the mediating effect of ego-resiliency on the relationship between burnout and depressive symptoms was examined. Results: A total of 226 participants (43.9%) were identified as having depressive symptoms. Happiness was associated with a lower risk of depressive symptoms, whereas burnout and social conflict were associated with a higher risk. Furthermore, ego-resiliency showed a significant mediating effect on the relationship between burnout and depressive symptoms. Being a basic or charge nurse; experiencing job dissatisfaction; being exposed to higher levels of burnout and social conflict; and having lower levels of happiness and ego-resiliency were significantly correlated with depressive symptoms. Conclusions Our findings suggest that intervention strategies aimed at enhancing happiness and ego-resiliency while reducing burnout and social conflict may help prevent and manage depressive symptoms among hospital nurses.

and Relevance: This case supports the value of imaging, clinicopathologic assessment, and histopathology in diagnosis, and suggests that supportive husbandry modification may provide temporary welfare benefit in affected snakes.

Background: Refractory cutaneous warts often persist despite conventional treatments. Pulsed dye lasers (PDLs) and long-pulsed neodymium-doped yttrium aluminum garnet (Nd:YAG) lasers are commonly used in clinical practice. However, comparative data on refractory cases remain limited. Methods: Following PRISMA 2020 guidelines, PubMed, Embase, Scopus, and Cochrane Library were searched through October 11, 2025, for studies evaluating PDL or Nd:YAG treatment for refractory warts. Head‑to‑head studies were meta-analyzed using Inverse Variance fixed‑effect odds ratios (ORs), whereas single‑arm evidence was summarized narratively following the SWiM guidelines. The primary outcome was complete clearance, with hemorrhagic complications as the key safety outcome. Results: Fifteen studies met the inclusion criteria: three head‑to‑head (n=224; 115 PDLs and 109 Nd:YAG lasers) and 12 single‑arm series. Complete clearance was similar between PDLs and Nd:YAG lasers (OR, 1.29; 95% confidence interval [CI], 0.66–2.50; I²=0%). Hemorrhagic complications occurred less frequently with PDLs (OR, 0.23; 95% CI, 0.07–0.74; I²=22%). Single-arm studies indicated broad clearance ranges (PDL, 5.1%–89.0%; Nd:YAG, 9.1%–100%). Conclusion PDLs and Nd:YAG lasers demonstrated comparable efficacies in treating refractory warts, and PDLs conferred a safety advantage for hemorrhagic events. The lesion site, thickness, bleeding tolerance, and patient context should be considered when selecting the treatment modality.

Background: With the aging population and advancements in medical care worldwide, the number of older patients with end-stage kidney disease continues to rise. This study aimed to identify factors associated with osteoporosis and osteopenia in older patients undergoing incident hemodialysis and assess their impact on mortality. Methods: We analyzed a large multicenter retrospective cohort of patients aged ≥70 years undergoing incident hemodialysis to identify factors associated with osteoporosis using logistic regression analysis and to assess the association of death with osteoporosis and osteopenia using Cox multivariable analysis. Results: Among 710 patients, 39.0% and 19.6% had osteoporosis and osteopenia, respectively. Osteoporosis was significantly associated with female sex, a history of fractures, and the absence of phosphate binder use. During a median follow-up of 36.8 months, 348 participants (58.8%) died. Mortality rates were the highest in the osteoporosis group (79.8%), followed by the osteopenia (77.2%) and normal bone mineral density (BMD) groups (35.2%). Cox regression analysis revealed that even after adjusting for covariates, the osteoporosis group was significantly associated with a higher mortality risk than the normal BMD group. Osteoporosis at the start of hemodialysis was significantly associated with higher mortality. Conclusion We should consider the importance of bone health in patients undergoing incident hemodialysis and pay attention to the use of phosphate binders and fracture prevention.

Background: Obesity is a well-known risk factor for chronic kidney disease and its progression. However, the impact of obesity on the renal function of the elderly population is uncertain. We investigated the association between obesity and renal outcomes in the elderly. Methods: We analyzed 130,504 participants from the Korean National Health Insurance Service-Senior cohort. Obesity was classified according to body mass index (BMI), sex-specific waist circumference (WC), and the presence of metabolic syndrome. The primary outcome was renal function decline, defined as a decline in the estimated glomerular filtration rate (eGFR) of at least 50% from baseline or new-onset end-stage renal disease. Results: During a follow-up period of 559,531.1 person-years (median, 4.3 years), 2,486 participants (19.0%; incidence rate of 4.44 per 1,000 person-years) showed renal function decline. A multivariate Cox proportional hazards model revealed that BMI/WC was not associated with renal function decline. However, the group with metabolic syndrome had a significantly increased risk of renal function decline compared to the group without metabolic syndrome (adjusted hazard ratio [HR], 1.24; 95% confidence interval [CI], 1.13–1.36). Compared with the non-metabolic syndrome group, the adjusted HRs (95% CI) for participants with one through five components were 0.96 (0.84–1.11), 1.10 (0.96–1.27), 1.24 (1.06–1.45), 1.37 (1.12–1.66), and 1.99 (1.42–2.79), respectively (p for trend < 0.001). Conclusion In elderly Korean adults, metabolic syndrome and the number of its components were associated with a higher risk of renal function decline, but BMI or WC was not significant.

Purpose: Atypical hyperplasia (AH) management remains controversial due to variable malignant disease progression rates. While Western studies report 10% to 25% upgrade rates, data from Asian populations, particularly from referral academic centers, are limited. We aimed to identify predictive factors for malignant upgrade in Korean women with AH at academic hospitals. Methods: This retrospective multi-institutional study analyzed 340 patients diagnosed with AH on initial biopsy who underwent subsequent excision at five Korean academic hospitals from 2000 to 2022. Malignant upgrade was defined as ductal carcinoma in situ or invasive cancer on the final pathology. Multivariate logistic regression was used to identify independent predictors of upgrades. Results: Among 340 patients (319 atypical ductal hyperplasia, 20 atypical lobular hyperplasia, and 1 mixed), 128 (37.6%) experienced a malignant upgrade, 98 (76.6%) to ductal carcinoma in situ, and 30 (23.4%) to invasive cancer. In multivariate analysis, multifocal atypia (odds ratio [OR], 25.61; 95% confidence interval [CI], 11.20–58.55; P<0.001) and Breast Imaging-Reporting and Data System 4c-5 lesions (OR, 11.02; 95% CI, 1.43–84.86; P=0.021) were significant predictors. Multifocal atypia showed an 84.4% upgrade rate. Core needle biopsy had higher upgrade rates than vacuum-assisted biopsy (45.2% vs. 20.0%; P<0.001). The upgrade rates decreased from 50% to 25% over the study period (P<0.05). Conclusion The 37.6% upgrade rate in this tertiary referral cohort exceeded that in Western reports, with multifocal atypia emerging as the strongest predictor. These findings support immediate excision for multifocal atypia while allowing individualized management for unifocal lesions with favorable imaging in Korean tertiary care settings.

Autoimmune hemolytic anemia (AIHA) is a rare immune-mediated disorder in children that can present as primary or secondary to other diseases. Here, we report an unusual case of steroid-refractory warm AIHA in an 11-year-old girl whose condition was ultimately cured after removal of a benign ovarian tumor. Despite receiving multiple lines of therapy—including corticosteroids, rituximab, cyclosporine, sirolimus, and mycophenolate mofetil—the patient experienced recurrent hemolysis and steroid dependence for nearly four years. Abdominopelvic imaging performed to evaluate fever revealed bilateral ovarian cystic lesions, including a left-sided dermoid cyst. Surgical resection of the tumor led to complete and sustained hematologic remission, with normalization of hemoglobin, bilirubin, and reticulocyte counts, allowing discontinuation of all immunosuppressive agents. No recurrence of hemolysis was observed during 18 months of follow-up. This case highlights the potential for benign ovarian tumors to act as a rare secondary cause of AIHA through paraneoplastic or immune cross-reactive mechanisms. Awareness of such associations is crucial when evaluating pediatric patients with refractory or relapsing AIHA, as identification and removal of an occult tumor may achieve definitive resolution of hemolysis and avoid long-term immunosuppression.

Background: Combined pelvic ring and acetabular fractures are complex injuries associated with high morbidity. Despite advancements in surgical techniques, limited data are available on the long-term functional outcomes and associated factors. This study aimed to identify the factors associated with functional outcomes in surgically treated patients with combined pelvic ring and acetabular fractures. Methods: This retrospective study included 25 adult patients who underwent definitive surgical fixation for radiologically confirmed combined pelvic ring and acetabular fractures at a Level I trauma center between 2005 and 2021, with a minimum clinical and radiological follow-up of 24 months. Surgical approaches included the Kocher–Langenbeck or modified Stoppa methods, tailored to fracture morphology. Matta–Saucedo and Matta criteria assessed the pelvic ring and acetabular reduction quality, respectively. Functional outcomes at 2 years were evaluated using the Rommens–Hessmann criteria. Neurological recovery was assessed clinically and by electromyography where indicated. The association between the injury characteristics and functional recovery was evaluated using t-tests and Fisher’s exact test. Results: The mean patient age was 40.4 years, and 72% were male. Transverse acetabular fractures (58.6%) and anteroposterior compression pelvic ring injuries (64%) were the most common injuries. Anatomic or congruent acetabular reduction (within 2–3 mm) was achieved in 89.6% of fractures and was significantly associated with superior functional outcomes (p = 0.002). Conversely, the pelvic ring reduction quality did not significantly correlate with functional outcomes (p = 0.314). Transverse acetabular fractures (p = 0.046) and initial neurological deficits (p = 0.032) were associated with poorer recovery. Among the patients with neurological injury, 60% achieved partial or full recovery. Overall, bony union occurred in 96% of cases, with a mean time to union of 14.3 weeks. Reported complications included neurological deficits (40%) and infections (8%). Conclusions Functional outcomes following the surgical fixation of combined pelvic and acetabular fractures are primarily influenced by the acetabular reduction quality and neurological status at presentation. Transverse fracture patterns are complex and associated with nerve injuries, posing additional challenges. These findings emphasize the importance of precise joint reduction and early neuroassessment. Further multicenter, prospective studies are warranted to optimize the management of these complex injuries.

Background: and Purpose Criteria for amyloid-related imaging abnormalities in anti-amyloid therapy are based on T2* gradient-recalled echo (GRE), but susceptibility-weighted imaging (SWI) is widely used, creating uncertainty. This study quantitatively compared the detectability of SWI and GRE for cerebral microbleeds and established evidence supporting distinct microbleed criteria for each. Methods: A systematic review and meta-analysis were conducted following PRISMA guidelines. PubMed and Embase were searched for studies directly comparing SWI and GRE up to August 8, 2024. Study quality was assessed with QUADAS-2. The pooled proportion of microbleed detection and detection ratio were calculated. Subgroup analyses were performed based on magnetic field strength (1.5 T vs. 3 T) and SWI slice thickness (<2 mm vs. ≥2 mm), equipment vendor, and study quality. Results: Thirteen studies were included. SWI detected cerebral microbleeds approximately 1.6times more effectively than GRE. At 3.0 T and 1.5 T, SWI exhibited 1.7-fold and 1.5-fold greater detectability, respectively. SWI with thinner slices (<2 mm) showed a 1.9-fold improvement, while thicker slices (≥2 mm) showed a 1.3-fold improvement. Subgroup analyses revealed no significant differences between vendors (0.61 vs. 0.60, p=0.89), or by study quality (0.61 vs. 0.59,p=0.89). Conclusions SWI detects cerebral microbleeds about 1.6 times more effectively than GRE, highlighting important differences between the two techniques. Cautious exploration of adjusted thresholds may be needed, and prospective validation in therapy-specific cohorts will be essential before clinical application.

Background: and Purpose Induced hypertension therapy (IHT) is effective for treating early neurological deterioration (END) in patients with single subcortical infarction (SSI). However, the underlying pathophysiology of SSI is diverse and may affect the efficacy of IHT. Methods: We reviewed patients with SSI who experienced END and received IHT were enrolled. END was defined as ≥2-point increase in the National Institutes of Health Stroke Scale (NIHSS) score, ≥1 motor point increase. IHT was performed by using phenylephrine infusion to raise systolic blood pressure by 10%–20% over baseline. SSI was classified into three subtypes: distal (dSSI), proximal (pSSI), and SSI with parental artery disease (SSIPAD; with stenosis at parental artery disease <50%). Responders were defined as patients who showed neurological improvement (decrease of ≥2 points in NIHSS, ≥1 motor point decrease) within one day after IHT initiation. Multivariable analysis identified factors associated with responders. Results: Characteristics were compared between responders and non-responders, and factors associated with response to IHT were investigated. Among 96 patients (mean age, 64.7± 12.9 years; 61.5% male), 49 (51.0%) patients were categorized as responders. Multivariable analysis showed that pSSI (adjusted odds ratio [aOR]=18.10, 95% confidence interval [CI] 5.04–80.60, p<0.001) and SSIPAD (aOR=4.56, 95% CI 1.31–19.00, p=0.024) were associated with a positive response to IHT compared to dSSI. Additionally, less white matter changes (Fazekas scale 0–1) were associated with a better response to IHT (aOR=0.15, 95% CI 0.03–0.67,p=0.019). Conclusions Response to IHT varied according to SSI subtypes and the severity of small vessel changes.
