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.

Background: Various perioperative therapeutic strategies have been used to minimize postoperative complications and enhance recovery. Music intervention has attracted increasing attention as a safe, noninvasive, and cost-effective approach with potential benefits for patient-centered postoperative outcomes. Accordingly, this study investigated the effect of intraoperative music on postoperative recovery quality, as assessed using the Quality of Recovery-40 (QoR-40) questionnaire, as well as its potential analgesic and antiemetic effects in patients undergoing arthroscopic knee surgery. Methods: Eighty-two patients were enrolled and allocated to either the music or control group. In the music group, patient-selected tracks were delivered intraoperatively via headphones. Postoperative recovery quality was assessed using the QoR-40 at 24 hours. Pain was evaluated 30 minutes, 2 hours, and 24 hours after arrival in the post-anesthesia care unit. The incidence of postoperative nausea and vomiting (PONV) was recorded at all time points. Results: Although the total QoR-40 scores did not differ between the groups, the music group demonstrated significantly higher physical comfort scores (p=0.006). The incidence of PONV at 24 hours was lower in the music group (p=0.048), whereas the postoperative pain scores and rescue analgesic requirements showed no significant differences at any assessment point. Conclusion In patients undergoing arthroscopic surgery, intraoperative music was associated with improvements in physical comfort and PONV, despite no significant difference in the total QoR-40 score.

Background: The heterogeneity of chronic kidney disease (CKD) and fragmented analysis methods hinder the precise identification of novel biomarkers. We addressed this challenge using two independent cohorts to integrate genomics and metabolomics, aiming to identify cause-specific biomarkers for CKD in the Korean population. Methods: A longitudinal genome-wide association study using the Cox proportional hazards model was conducted using the Ansan and Ansung cohort. To validate these genomic biomarkers and integrate them with plasma metabolomics biomarkers, we utilized a hospital-based biopsy cohort to identify cause-specific CKD biomarkers. Within the biopsy cohort, we analyzed four disease subsets, including type 2 diabetic kidney disease (DKD), hypertensive nephropathy (HN), immunoglobulin A nephropathy (IgAN), and membranous nephropathy (MN), and compared them with healthy individuals. Significant single nucleotide polymorphisms(SNPs) and metabolites for each CKD subset were identified through logistic regression and correlation-based network analyses. Subsequently, we analyzed the risk of disease progression associated with the identified pairs. Results: A total of 448 variants associated with CKD occurrence were identified, with significant differences in several genetic variants and metabolites observed among patients with DKD, HN, IgAN, and MN compared to healthy individuals. Among 36 SNP-metabolite pairs, those involing FOXB1 and ZFP42 were associated with DKD, whereas pairs involving MMRN1 and SYNJ2 were linked to MN. Notably, the rs1025170 variant in FOXB1 and tyrosine pair was correlated with DKD progression. Conclusion Integrating genomics and metabolomics across independent cohorts enables the discovery of cause-specific biomarkers for the occurrence and progression of CKD in the Korean population.

Background: Hypertensive patients tend to have an increased risk of hypotension during anesthesia induction, which can result in adverse outcomes. This study aimed to compare hemodynamic stability with remimazolam versus propofol in hypertensive patients. Methods: This meta-analysis analyzed randomized controlled trials investigating the hemodynamic outcomes of remimazolam versus propofol during anesthesia induction in hypertensive adults. A systematic search of electronic databases was conducted in November 2024. Results: Six studies were included in the final analysis. The administration of remimazolam significantly lowered the risk of hypotension (risk ratio [RR] = 0.711, 95% CI [0.545–0.929], I2 = 67.54%) and bradycardia (RR = 0.256, 95% CI [0.101–0.649], I2 = 0.0%). It also resulted in a higher minimum mean arterial pressure (mean difference [MD] = 9.023 mmHg, 95% CI [0.243–17.802], I2 = 97.50%) and higher minimum heart rate (MD = 7.200 beats/min, 95% CI [1.960–12.441], I2 = 86.40%). Despite these findings, substantial heterogeneity was observed in continuous outcomes. The trial sequential analysis revealed that none of the outcomes reached the required information size. Conclusions The administration of remimazolam showed a trend toward superior hemodynamic stability compared with propofol during anesthesia induction in hypertensive patients, especially in minimizing the incidence of hypotension and bradycardia. However, the trial sequential analysis results remain inconclusive, the current evidence is limited by small sample sizes, and larger trials are needed to confirm our findings.

Objective: This study aimed to evaluate reproductive outcomes according to the timing of testicular sperm retrieval. Methods: The study included 282 infertile couples divided into three groups: group A (freeze-thawed testicular sperm extraction [TESE] sperm, n=233), group B (fresh TESE sperm collected 1 day before ovum pickup, n=22), and group C (fresh TESE sperm collected on the same day as ovum pickup, n=27). The indications for TESE were surgically uncorrectable azoospermia or ejaculation failure, often accompanied by medical comorbidities such as diabetes mellitus and spinal cord injury. The outcome parameters assessed were fertilization rates, embryo quality, and clinical pregnancy rates. Results: The mean paternal age was 36.8±5.7 years, and the mean maternal age was 32.6±3.5 years. The mean duration of infertility was 2.9±1.8 years. The fertilization rates were 70.7%, 78.9%, and 73.0% for groups A, B, and C, respectively (p=0.047). The percentages of good-quality embryos were 68.2%, 65.3%, and 48.4%, respectively (p=0.007); specifically, the percentage of good-quality embryos was significantly lower in group C compared with the other two groups. Clinical pregnancy rates per transfer were similar at 51.1%, 50.0%, and 48.1% (p=0.958), with no differences observed in miscarriage rates. Conclusion Testicular sperm retrieval can be safely performed 1 day before ovum pickup, resulting in favorable fertility outcomes.

Janus kinase (JAK) inhibitors are an important treatment option for ulcerative colitis, providing rapid onset of action, oral administration, and efficacy even after biologic failure. The 3 approved agents—tofacitinib, filgotinib, and upadacitinib—differ in JAK isoform selectivity, leading to clinically meaningful differences in efficacy and safety. Evidence from network meta-analyses, clinical trials, and real-world studies consistently shows that upadacitinib provides the highest efficacy for induction and maintenance of remission, whereas filgotinib demonstrates the most favorable safety profile. The strong efficacy of upadacitinib and tofacitinib is particularly relevant in patients with severe disease, including acute severe ulcerative colitis, and upadacitinib maintains high efficacy regardless of prior advanced therapy exposure. JAK inhibitors also benefit extraintestinal manifestations. Although risks such as herpes zoster, serious infection, thromboembolism, and major cardiovascular events differ among agents, long-term data suggest generally acceptable safety when used appropriately. Intraclass JAK-to-JAK cycling is feasible, with about half of patients achieving steroid-free clinical remission in retrospective cohorts. Based on mechanistic, clinical, and real-world evidence, filgotinib may be a first-line option for patients with lower disease activity or when safety is a priority, whereas upadacitinib or tofacitinib may be preferred in higher disease activity. Strategically selecting agents may improve durability and outcomes.

Purpose: To assess long-term outcomes of vesicostomy on bladder capacity (BC) and voiding function in non-neurogenic bladder, and explore the association between kidney ultrasonographic findings and renal function. Materials and Methods: Thirty-four patients under 2 years at the time of vesicostomy formation (2005–2020) with ≥3 years of follow-up were reviewed. Patients were further stratified based on neurogenic bladder status. Twenty-one patients were nonneurogenic. A subgroup analysis of 7 patients under 3 months with primary vesicoureteral reflux (VUR) and compromised renal function was conducted. Results: The median age at vesicostomy formation was 1.0 months (interquartile range [IQR] 0.0–3.5); the median duration of vesicostomy was 16.0 months (IQR 8.0–21.0). At a median age of 93.0 months (IQR 59.5–117.5), all patients achieved spontaneous micturition and continence. Eleven patients (52.4%) showed bell-shaped voiding patterns. Five patients showed interrupted (n=2) or plateau (n=3) patterns. With the exemption one patient, all patients with primary VUR showed bell-shaped curves. None initiated clean intermittent catheterization during follow-up. The median BC-to-estimated BC in patients with non-neurogenic bladder and primary VUR was 0.9 (IQR 0.7–1.1) and 0.9 (IQR 0.8–1.1), respectively. Three patients underwent revision due to prolapse. The glomerular filtration rate (GFR) was improved by 68.9% compared to the baseline (p=0.045). Parenchymal abnormalities on kidney ultrasonography were associated with decrease in GFR. Conclusions Vesicostomy in non-neurogenic bladder patients was associated with recovery of BC, preservation of continence, and improved renal function. Parenchymal abnormalities on ultrasonography predicted lower GFR.

Background: and Purpose Whole-exome sequencing (WES) is a valuable tool for identifying causative mutations in adult moyamoya disease (MMD), thereby advancing our understanding of the genetic mechanisms underlying this condition. Here, we conducted the first WESbased association study aimed at identifying genetic modifiers implicated in MMD. Methods: This WES study involved 160 patients with MMD and 189 controls from a multicenter hospital-based biobank, and evaluated combined annotation-dependent depletion (CADD) scores. Mutant-allele frequencies were compared in 369,121 individuals derived from the UK Biobank (UKB) WES. Mutant-allele risk scores (MARSs) were created based on WESidentified mutations. Gene-based association analyses and pooled analyses in East-Asian populations were further performed. Results: Fourteen mutations reached the genome-wide significance criterion (p<5×10-8 ), among which the p.R4810K mutation in the ring finger protein 213 gene (RNF213) showed the strongest significance (odds ratio=117.4, p=8.54×10-24 ). Notably, two mutations—p.G576S (alpha-glucosidase [GAA]) and p.D54N (charged multivesicular body protein 6 [CHMP6])— exhibited high CADD scores of 32 and 25, respectively, whereas the RNF213 p.R4810K mutation demonstrated a moderate deleteriousness score of 10.63. Fourteen mutations exhibited significant differences in allele frequencies between patients and UKB controlled data (p<1×10-8 ).The MARS9 model (incorporating nine missense mutations) showed better predictability for MMD (90.89%). The analysis of gene-based associations revealed four candidate genes: GAA, RNF213, CHMP6, and CARD14 (p=5×10-19 to 4×10-7 ). The subsequent pooled analyses validated four mutations in East Asian populations: p.V1195M, p.D1331G, p.S2334N, and p.R4810K (p<3×10-8 ). Conclusions This pioneering study has corroborated the significance of p.R4810K and identified several causative mutations predisposing patients to MMD, which helps to improve the understanding of its polygenetic nature.

Purpose: This study examined satisfaction levels and educational needs related to the Maternal and Newborn Health Care Support Program in South Korea, focusing on differences based on demographic characteristics, including maternal age, birth order, delivery method, and prenatal health status. Methods: A cross-sectional survey was conducted among 136 women who utilized the Maternal and Newborn Health Care Support Program between 2021 and 2022. The data were collected using a structured online questionnaire. Descriptive statistics, chi-square tests, and multivariable logistic regression analyses were employed to assess satisfaction levels and educational needs across the demographic subgroups. Results: Satisfaction with standard services varied across demographic groups. Younger mothers reported greater satisfaction with the service content, whereas older mothers expressed higher satisfaction with policy-related aspects. Women who underwent cesarean sections reported lower overall satisfaction compared to those who had vaginal deliveries, particularly regarding service content and the method of program administration. Mothers who experienced postpartum depressive symptoms demonstrated lower satisfaction across most categories. First-time mothers reported higher educational needs across all areas, while mothers with two or more children exhibited greater educational needs specifically related to maternal safety. Conclusion The findings suggest the need for differentiated and tailored service strategies. Efforts to enhance service quality and address diverse needs should entail strengthening the competencies of care workers, expanding supervisory systems for healthcare professionals, and providing greater support for postpartum mental health.

Purpose: Hereditary spastic paraplegia (HSP) refers to a group of genetic neurodegenerative diseases marked by gradually worsening spasticity and hyperreflexia in the lower extremities. This study aimed to describe the clinical and genetic characteristics of Korean patients with spastic paraplegia. Materials and Methods: We retrospectively reviewed medical records of 69 patients with spastic paraplegia from 54 unrelated families between 2002 and 2024. Genetic, clinical, electrophysiological, and radiological features were comprehensively analyzed. Results: Causative genes were identified in 34 (63%) of 54 unrelated families; SPAST, detected in 26 families, was the most prevalent. Seven novel pathogenic variants were identified. Clinically, the median age of symptom onset was 25 years [14.0–37.0]. Out of 69 patients with spastic paraplegia, 51 (74%) presented with the pure form of spastic paraplegia, which included all patients with SPG4. Spastic gait was a universal feature in all patients. Urinary dysfunction was present in 42 (61%) patients. Additional neurologic manifestations included peripheral neuropathy 9 (13%), cognitive impairment 5 (7%), upper limb weakness 4 (6%), dysarthria 4 (6%), dysphagia 3 (4%), ataxia 3 (4%), and scoliosis 1 (3%). Brain MRI findings demonstrated a thin corpus callosum in two patients with SPG11; all patients with SPG4 had normal findings. Spine MRI revealed spinal cord atrophy in 16 (27%) patients, including 6 (21%) patients with SPG4. Conclusion The study comprehensively reviewed genetic and clinical spectra of spastic paraplegia in Korean patients, emphasizing the predominance of SPAST as the causative gene and underscoring the genetic and phenotypic heterogeneity of spastic paraplegia.
