Background: This study aimed to report the radiological outcomes and risk factors for malalignment of fractures in the distal onefourth of the tibia treated with intramedullary nailing via the infrapatellar approach. Methods: This study retrospectively analyzed 60 patients (37 men and 23 women; mean age, 45.4 years) who had distal onefourth tibial fractures and were treated with intramedullary nailing using the infrapatellar approach. These patients were treated between January 2009 and December 2021, with a minimum follow-up of 1 year. Fractures were classified according to the Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association system: 25 were type 42A, 30 were type 42B, and 5 were type 43A. Radiographic outcomes focused on bone union and malalignment, defined as a valgus deviation greater than 5° compared to the unaffected side. Potential risk factors for malalignment, including open fractures (9 cases, 15%), distal tibial extension (20 cases, 33%), and distal fibular fractures (24 cases, 40%), were documented. Results: Bone union was achieved in all cases, with an average duration of 3.2 months (range, 3–5 months). No cases of postoperative wound infection or neurovascular damage were observed. The average coronal plane malalignment was 2.6° of valgus (range, 0°–9.3°), with significant malalignment (over 5°) occurring in 5 patients (8.3%). Comparison of the malalignment (n = 5) and normal (n = 55) groups showed a statistically significant difference in distal bone fragment length (average, 66.5 mm vs. 77.2 mm;p = 0.008) but no significant differences in other variables. A change-point analysis revealed that cases with a primary fracture line < 65 mm showed 4.5° of coronal malalignment, while those with > 65 mm showed 2.3°; the difference was statistically significant (p = 0.01). Conclusions Intramedullary nailing using the infrapatellar approach for distal one-fourth tibial fractures results in successful bone union with a low incidence of valgus malalignment. However, careful attention is necessary to prevent angular deformities, especially when the distal fragment is short.

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.

Objective: This study aims to explore the association between work-related stress of healthcare workers in response to the coronavirus disease-2019 (COVID-19) pandemic and their depressive symptoms. Additionally, it focuses on the impact of insomnia symptoms, interpersonal factors, and resilience on depressive symptoms. Methods: The results of an anonymous survey of 329 healthcare workers were analyzed, including the Stress and Anxiety to Viral Epidemics-3 items, Insomnia Severity Index, Interpersonal Needs Questionnaire, Connor–Davidson Resilience Scale-2 items, and Patient Health Questionnaire-9 items. Mediation analysis assessed whether insomnia symptoms, resilience, and interpersonal factors mediate the association between work-related stress and depressive symptoms. Results: Work-related stress directly influenced depressive symptoms (standardized estimator=0.11, p=0.010, 95% confidence interval [CI] 0.03–0.19). The association between the former and latter was positively mediated by insomnia symptoms (standardized estimator=0.10, p<0.001, 95% CI 0.05–0.14), thwarted belongingness (standardized estimator=0.04, p=0.006, 95% CI 0.01–0.07), and perceived burdensomeness (standardized estimator=0.05, p=0.002, 95% CI 0.02–0.08) and was negatively mediated by resilience (standardized estimator=0.02, p=0.041, 95% CI 0.0001–0.04). Conclusion This study highlights the connection between heightened work-related stress experienced by healthcare workers amid the COVID-19 pandemic and the subsequent development of depressive symptoms mediated by insomnia, interpersonal factors, and resilience. Interventions that focus on building resilience could be pivotal in mitigating the detrimental mental health consequences of workplace stress among healthcare workers in a viral epidemic.
