Surgery is the most important curative treatment for medullary thyroid carcinoma (MTC). The relationship between surgeon volume (the number of surgeries performed) and short-term surgical outcomes, such as increased postoperative complication or costs, is well established. This study evaluated whether surgeon volume influenced long-term oncologic outcomes. We retrospectively reviewed 246 patients diagnosed with MTC after initial thyroid surgery from 1995 to 2019. After exclusion, 194 patients were eligible for inclusion in the study. Surgeons were categorized as low/intermediate volume (fewer than 100 operations per year) or high volume (at least 100 operations per year). Of the 194 included patients, 60 (30.9%) developed disease recurrence, and 9 (4.6%) died of MTC during the median follow-up of 92.5 months. Having a low/intermediate-volume surgeon was associated with high disease recurrence (log-rank test, p < 0.001). After adjustment for age, sex, tumor type (sporadic versus hereditary), primary tumor size, presence of central lymph node metastasis (LNM), presence of lateral LNM, extrathyroidal extension, and positive resection margin, surgeon volume was a significant factor for disease recurrence (hazard ratio 2.28, p = 0.004); however, cancer-specific survival was not affected by surgeon volume (hazard ratio 4.16, p = 0.115). Surgeon volume is associated with long-term oncologic outcome. MTC patients will be able to make the best decisions for their treatment based on the results of this study.

Performing a cardiac CT scan before ablation provides a better understanding of the anatomical variations of the left atrium and pulmonary veins, as well as an analysis of coronary anatomy and the calcium score. read more The aim of the present study was to determine whether the CT characteristics of patients with unknown CAD have an impact on recurrence of AF. This monocentric retrospective study included patients with AF who had undergone cardiac CT prior to a single ablation. Among the 229 patients included in the study, 70 (30.5%) presented AF recurrence between 3 and 12months after a single ablation. The prevalence of CAD confirmed by CT coronary angiogram and the coronary calcium score were similar in the two groups. Patients with recurrent atrial fibrillation had a significantly higher LAVI evaluated by CT scan than patients without recurrence. The ROC curve determined an optimal LAVI threshold of 49mL/m . In multivariate analysis, the LAVI measured by CT scan was independently associated with the risk of AF recurrence. Our study confirms that CAD is not a predictor of AF recurrence after a single ablation, unlike the LAVI. Further studies are necessary to re-evaluate the long-term conclusions of this work.

Individuals with ASD and age- and gender-matched controlled counterparts (total n = 32,812) were assessed for COVID-19 infection rates and hospitalizations. Results indicated higher infection rates among individuals with ASD, with the largest effect among individuals aged 40-60 (OR = 2.05, 95%CI 1.33-3.15, p less then .001), as well as higher odds for hospitalizations, evident primarily in men (OR = 2.40, 95%CI 1.14-5.02, p = 0.02) but not women. Medical and environmental risk factors may associate ASD with higher infection and morbidity rates. Healthcare policy providers should consider proactive steps to protect this population from the
