The prevalence of postpartum depression (PPD) in Asia is reported to range from 13.53% to 22.31%. However, there remains a gap in the identification of PPD, particularly regarding cultural cutoff points. Therefore, the purpose of this scoping review was to determine the prevalence and associated factors of PPD in Eastern, South-eastern, Western, and Southern Asian countries and analyze the cutoff points of the Edinburgh Postnatal Depression Scale (EPDS) used across these countries. Following Arksey and O'Malley’s five-step scoping review framework, the population was defined as mothers, the concept as the EPDS, and the context as the Asian region. A literature search was conducted using PubMed, Embase, CINAHL, PsycINFO, and Web of Science. The data analysis focused on demographic characteristics, EPDS cutoffs and features, PPD prevalence, and its associated factors. Nineteen studies were selected. Most countries used translated versions of the EPDS with demonstrated reliability and validity. The cutoff scores varied, with most using scores of 10 or higher. The prevalence of PPD ranged from 5.1% to 78.7%. Key associated factors for PPD included cultural factors such as relationships with in-laws and preferences for the newborn’s sex. To improve the accuracy of PPD screening in Asia, the EPDS should be used consistently, and appropriate cutoff criteria must be established. In addition, prevention strategies and programs that reflect the cultural characteristics and social context of Asia need to be developed for the early detection and prevention of PPD.

Purpose: This study focused on analyzing the contact pressure and area on different patellar component designs in total knee arthroplasty (TKA) to evaluate biomechanics related to the patellofemoral (PF) joint. Materials and Methods: The patellar components studied included the dome design, modified dome design, and anatomical design implants. Using finite element analysis and mechanical testing, the pressure and area were evaluated. The first loading condition was simulated at flexion angles of 0°, 15°, 45°, 90°, 120°, and 150°. The second loading condition was simulated for a clinically relevant scenario, involving a 2-mm medial shift at a flexion angle of 45°. Results: For both the modified dome and anatomical designs, the contact area and pressure increased with the flexion angle. The dome design reached its maximum contact area at a flexion angle of 120°. Among the designs, the anatomical design had the largest contact area and a lower contact pressure compared to the dome and modified dome designs. However, when a medial shift of 2 mm was simulated at a 45° flexion angle, which can occur clinically, the anatomical design showed edge contact, leading to higher contact pressure and reduced contact area. In contrast, the modified dome design demonstrated the lowest contact pressure and the greatest contact area under the same shifted conditions. Conclusion These findings suggest that the design of the patellar component significantly affects patellar biomechanics and stability. Specifically, the modified dome design showed improved biomechanical effects in clinically relevant scenarios. Therefore, patellar components with a modified dome design are expected to better manage PF joint pain and reduce complications in TKA.

Objectives: Excessive sedentary behavior in youth is a major global issue, contributing to the rise in childhood obesity and metabolic diseases. International public health authorities have issued guidelines recommending that children and adolescents limit their daily sedentary time, including screen time. However, to date, no studies have explored the relationship between sedentary behavior as an exposure factor and skeletal muscle strength and mass as outcomes in this population. The present study investigated the association of sedentary behavior with handgrip strength (HGS) and appendicular lean mass (ALM) among United States adolescents. Methods: A total of 1449 adolescent participants from the National Health and Nutrition Examination Survey (2011-2014) were included. Information on sedentary behavior, specifically daily sedentary time, was obtained through a self-reported questionnaire. Muscular parameters, including HGS and ALM, were measured. To adjust for differences in body size, these parameters were divided by body mass index (BMI) and weight. Linear regression analyses were performed to evaluate the associations between daily sedentary time and each muscular parameter, adjusting for age, sex, ethnicity, annual family income, and moderate-to-vigorous physical activity (MVPA). Results: The linear regression analyses revealed negative associations between daily sedentary time and all muscular parameters, apart from absolute ALM. These included HGS (β, -0.265; standard error [SE], 0.074; p=0.001), HGS/BMI (β, -0.021; SE, 0.004; p<0.001), HGS/weight (β, -0.008; SE, 0.002; p<0.001), ALM/BMI (β, -0.008; SE, 0.003; p=0.010), and ALM/weight (β, -0.003; SE, 0.001; p=0.005). Conclusions After adjusting for MVPA, daily sedentary time was inversely associated with HGS, HGS/BMI, HGS/weight, ALM/BMI, and ALM/weight in United States adolescents.

Purpose: This study evaluated the postoperative quality of life (QoL) after various types of gastrectomy for gastric cancer. Materials and Methods: A multicenter prospective observational study was conducted in Korea using the Korean Quality of Life in Stomach Cancer Patients Study (KOQUSS)-40, a new QoL assessment tool focusing on postgastrectomy syndrome. Overall, 496 patients with gastric cancer were enrolled, and QoL was assessed at 5 time points: preoperatively and at 1, 3, 6, and 12 months after surgery. Results: Distal gastrectomy (DG) and pylorus-preserving gastrectomy (PPG) showed significantly better outcomes than total gastrectomy (TG) and proximal gastrectomy (PG) with regard to total score, indigestion, and dysphagia. DG, PPG, and TG also showed significantly better outcomes than PG in terms of dumping syndrome and worry about cancer. Postoperative QoL did not differ significantly according to anastomosis type in DG, except for Billroth I anastomosis, which achieved better bowel habit change scores than the others. No domains differed significantly when comparing double tract reconstruction and esophagogastrostomy after PG. The total QoL score correlated significantly with postoperative body weight loss (more than 10%) and extent of resection (P<0.05 for both).Reflux as assessed by KOQUSS-40 did not correlate significantly with reflux observed on gastroscopy 1 year postoperatively (P=0.064). Conclusions Our prospective observation using KOQUSS-40 revealed that DG and PPG lead to better QoL than TG and PG. Further study is needed to compare postoperative QoL according to anastomosis type in DG and PG.

Background: s/Aims: Balancing surgical risks and benefits is crucial for managing non-functional pancreatic neuroendocrine tumors (NF-PNETs). Despite high postoperative pancreatic fistula (POPF) rates, studies on postoperative complications of sporadic NFPNETs are scarce. Thus, this study aimed to investigate postoperative complications and identify risk factors for POPF. Methods: A retrospective review of 166 NF-PNET surgeries performed at Severance Hospital between February 2000 and August 2023 was conducted. Results: Age > 65 years and higher American Society of Anesthesiology (ASA) grade were not significantly correlated with severe complications (odds ratio [OR]: 1.10, p = 0.871 and OR: 1.47, p = 0.491, respectively). Surgical procedures included enucleation (13.9%), distal pancreatectomy (50.0%), central pancreatectomy (4.8%), pancreaticoduodenectomy (PD) (26.5%), and total pancreatectomy (4.8%). Severe complications occurred in 12.05% of surgeries. The overall incidence of all POPFs including biochemical leaks was 53%, while clinically relevant POPF (grade B or C) occurred in 7.8% of patients. Logistic regression showed that PD (OR: 3.94, p = 0.092) tended to be risk factor for POPF and that diameter of the main pancreatic duct (MPD) ≤ 3 mm was a significant risk factor for POPF (OR: 0.22, p = 0.008). A pancreas thickness (PT)/MPD ratio > 4.47 on preoperative computed tomography predicted all POPFs in PD patients (OR: 11.70, p = 0.001). Conclusions Age and comorbidities had no significant impact on surgical outcomes. PD was associated with higher serious complications and POPF rates. The PT/MPD ratio is a valuable preoperative tool for predicting POPF risk in PD patients.

Purpose: This study aimed to examine the effects of gonadotropin-releasing hormone agonist (GnRHa) treatment on final height outcomes in girls with idiopathic central precocious puberty (CPP) from the start of treatment to their postmenarche visit. Methods: We conducted a retrospective analysis of 200 girls with idiopathic CPP who received GnRHa therapy, focusing on auxological and clinical outcomes at treatment initiation, treatment completion, and the last, postmenarche visit. Results: The mean chronological age (CA) at GnRHa treatment initiation was 8.24±0.73 years. The mean duration of GnRHa treatment was 3.12±0.81 years. The average age at menarche was 12.73±0.56 years, occurring a mean of 17.15±5.52 months after completing GnRHa therapy. The predicted adult height (PAH) standard deviation score (SDS) after menarche (0.48±0.99) was significantly greater than before treatment (-1.33±1.46) (P<0.001). Factors including greater bone age advancement (P<0.001), lower height SDS for CA at treatment initiation (P<0.001), and higher midparental height SDS (P=0.001) were positively associated with an increase in PAH SDS at the last visit. However, near-final height and the increase in PAH SDS at the last visit were not significantly different between patients who received early treatment (<8 years) and those who received later treatment (8–9 years). Conclusion GnRHa treatment improved the final height outcomes in all girls with CPP, including those treated between 8 and 9 years of age.

Purpose: This study aimed to evaluate the outcomes of arthroscopic scaphocapitate fusion with lunate preservation, without autologous bone grafts, in stage III Kienböck disease, which causes significant wrist dysfunction due to lunate necrosis. Methods: Nine patients with stage III Kienböck disease underwent arthroscopic scaphocapitate fusion with lunate preservation from 2017 to 2022. Bone substitutes were used instead of autologous bone grafts: demineralized bone matrix, allogenic cancellous bone chips, and a bone substitute composed of hydroxyapatite combined with recombinant human bone morphogenetic protein-2. The clinical outcomes assessed were pain visual analogue scale (VAS), grip strength, wrist range of motion (ROM), Patient-Rated Wrist Evaluation (PRWE), and Disabilities of the Arm, Shoulder, and Hand (DASH) scores. Radiological assessments included bone union and modified carpal height ratio (MCHR). Results: At a mean follow-up of 22.7 months, all patients achieved bone union, with an average time to union of 8 weeks. Significant improvements were observed in wrist ROM (mean increase from 58.3° to 75.6°, p=0.001), grip strength (29.4% to 71.8% of the contralateral side, p<0.001), DASH scores (43.9 to 17.5, p<0.001), PRWE scores (45.2 to 18.0, p<0.001), and pain VAS (5.7 to 2.9, p<0.001). The mean MCHR decreased slightly from 1.41 to 1.39 (p<0.001). Conclusion Arthroscopic scaphocapitate fusion with lunate preservation, without autologous bone grafts, effectively improved pain, function, and anatomical outcomes in stage III Kienböck disease. Further research is needed to validate these findings.

Purpose: The purpose of this study was to analyze the educational content of breast cancer nursing literature and to identify the educational needs of nurses in caring for breast cancer patients. Methods: This descriptive study was employed using a mixed method that applied both deductive and inductive approaches to analyze the educational content of literature and to evaluate the educational needs of nurses. Results: Breast cancer nursing literature was organized into 4 categories, 16 subcategories, and 39 contents, with the categories consisting of “Concept of Breast Cancer,” “Diagnosing Breast Cancer,” “Treatment of Breast Cancer,” and “Management of Breast Cancer Patients.” In addition, educational needs for nursing breast cancer patients were categorized into 5 categories, with 13 subcategories based on 146 main statements. The categories consisted of “Need to Provide Structured Training Opportunities,” “Preference for Media-Based Educational Methods,” “Education Reflecting Clinical Practice,” “Education for Strengthening Competence in Emotional Care,” and “Difficulty and Stress in Performing Nursing Skills.” The analysis results of educational needs showed that nurses desire to systematically and sufficiently receive practical and educational content through preferred educational methods. However, analysis of breast cancer nursing literature revealed a gap between the educational content provided and educational needs due to the lack of practice-oriented breast cancer nursing information and the latest opinions. Conclusion This study suggests the need to develop a practical and effective breast cancer nursing education program to enhance the breast cancer nursing competency of clinical nurses.
