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: Hypertrophic cardiomyopathy (HCM) needs careful differentiation from other cardiomyopathies. Current guidelines recommend genetic testing, but genetic data on differential diagnoses and their relation with clinical outcomes in HCM are still lacking.This study aimed to investigate the prevalence of genetic variants and the proportion of other cardiomyopathies in patients with suspected HCM in Korea and compare the outcomes of HCM according to the presence of sarcomere gene mutation. Methods: We enrolled 1,554 patients with suspected HCM having left ventricular hypertrophy on transthoracic echocardiography between April 2012 and February 2023. Patients who declined genetic testing or who had pure apical HCM without a familial history were excluded. Genetic testing was performed using a next-generation sequencing panel or wholeexome sequencing for cardiomyopathies. We performed cardiovascular magnetic resonance if the diagnosis was inconclusive. Genotype-positive HCM was defined as sarcomere gene mutations of pathogenic or likely pathogenic variants. Adverse clinical outcomes were defined as a composite of all-cause death, resuscitated cardiac arrest, heart failure-related admission, appropriate implantable cardioverter defibrillator shocks, and stroke. Results: Of 492 patients (mean age 49.6 ± 14.7 years, 29.4% women) who underwent genetic testing, 214 (43.5%) had disease-causing gene mutations. After combining gene tests, multi-imaging modality, and clinical information, 447 (90.9%) had HCM, and 27 (5.5%) had Fabry disease. Among the HCM patients, 182 (40.7%) were genotype-positive, and 265 (59.3%) were genotype-negative. Kaplan–Meier curve analysis showed that genotype-positive HCM patients experienced more composite outcomes (log-rank, P < 0.001). In multivariable Cox analysis, non-sustained ventricular tachycardia (NSVT) (hazard ratio [HR], 1.91; 95% confidence interval [CI], 1.17–3.12; P = 0.010), left ventricular ejection fraction (LVEF) < 50% (HR, 5.50; 95% CI, 2.68–11.27; P < 0.001), LA reservoir strain (HR, 0.96; 95% CI, 0.93–0.99;P = 0.037), and positive sarcomere gene mutation (HR, 1.70; 95% CI, 1.04–2.78; P = 0.034) were significantly association with composite outcomes. Sarcomere gene mutation had incremental value for predicting adverse outcomes added on NSVT and LVEF < 50%. Conclusion Genetic testing is helpful in diagnosing HCM, and sarcomere gene mutations in HCM are significantly associated with clinical outcomes.

Background: We aimed to examine the prevalence of burnout among imaging cardiologists in Korea and to identify its associated factors. Methods: An online survey of imaging cardiologists affiliated with university hospitals in Korea was conducted using SurveyMonkey ® in November 2023. The validated Korean version of the Maslach Burnout Inventory-Human Service Survey was used to assess burnout across three dimensions: emotional exhaustion, depersonalization, and lack of personal accomplishment. Data on demographics, work environment factors, and job satisfaction were collected using structured questionnaires. Results: A total of 128 imaging cardiologists (46.1% men; 76.6% aged ≤ 50 years) participated in the survey. Regarding workload, 74.2% of the respondents interpreted over 50 echocardiographic examinations daily, and 53.2% allocated > 5 of 10 working sessions per week to echocardiographic laboratory duties. Burnout levels were high, with a significant proportion of participants experiencing emotional exhaustion (28.1%), depersonalization (63.3%), and a lack of personal accomplishment (92.2%). Younger age (< 50 years) was correlated with higher emotional exhaustion risk, while more research time was protective against burnout in the depersonalization domain. Factors, such as being single, living with family, and specific job satisfaction facets, including uncontrollable workload and value mismatch, were associated with varying levels of burnout risk across different dimensions Conclusion Our study underscores the high burnout rates among Korean imaging cardiologists, attributed to factors such as the subjective environment and job satisfaction.Hence, evaluating and supporting cardiologists in terms of individual values and subjective factors are important to effectively prevent burnout..
