Background: Sunitinib, commonly used for metastatic renal cell carcinoma (mRCC), often induces hypothyroidism, affecting 27 to85% of patients. There are clues suggesting an association between sunitinib-induced hypothyroidism and improved survival outcomes. This study aims to identify the predictive factors of sunitinib-induced hypothyroidism and evaluate whether the occurrence of overt or subclinical hypothyroidism predicts tumor outcome in patients with mRCC. Methods: Patients administered to sunitinib for mRCC was included in this retrospective study. Log-rank test and Cox proportional hazards model were conducted to identify predictive factors of hypothyroidism and prognostic factors of progression-free survival (PFS) and overall survival (OS). Results: A total of 156 patients with mRCC treated with sunitinib were included. Predictive factors of sunitinib-induced hypothyroidism werefemale (odds ratio (OR), 2.77), sunitinib-induced hypertension (OR, 2.99) and dose reduction of sunitinib due to intolerance (OR, 3.57). Sunitinib-induced overt hypothyroidism was a significant prognostic factor in predicting PFS and OS (hazard ratio, 0.38 and 0.23, respectively). Thyroid hormone replacement did not have an influence on PFS and OS. Conclusions Female patients, patients who experienced sunitinib-induced hypertension and sunitinib dose reduction are at higher risk of hypothyroidism and need close monitoring. Overt hypothyroidism is a strong prognostic factor of sunitinib treatment outcome in mRCC patients and thyroid hor-mone replacement does not have a negative effect on tumor outcome.

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..
