Cardiovascular disease has been recognized as a major determinant of coronavirus disease 2019 (COVID-19) vulnerability and severity. Angiotensin-converting enzyme (ACE) 2 is a functional receptor for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and is up-regulated in patients with heart failure. We sought to examine the potential association between reduced left ventricular ejection fraction (LVEF) and the susceptibility to SARS-CoV-2 infection. Of the 1162 patients with acute coronary syndrome (ACS) who underwent percutaneous coronary intervention between February 2014 and October 2018, we enrolled 889 patients with available clinical follow-up data. Follow-up was conducted by telephone interviews 1month after the start of the French lockdown which began on 17 March 2020. Patients were divided into two groups according to LVEF <40% (reduced LVEF) (n=91) or ≥40% (moderately reduced+preserved LVEF) (n=798). The incidence of COVID-19-related hospitalization or death was significantly higher in the reduced LVEF group as compared with the moderately reduced+preserved LVEF group (9% vs. 1%, P< 0.001). No association was found between discontinuation of ACE-inhibitor or angiotensin-receptor blockers and COVID-19 test positivity. By multivariate logistic regression analysis, reduced LVEF was an independent predictor of COVID-19 hospitalization or death (odds ratio 6.91, 95% confidence interval 2.60 to 18.35, P< 0.001). In a large cohort of patients with previous ACS, reduced LVEF was associated with increased susceptibility to COVID-19. Aggressive COVID-19 testing and therapeutic strategies may be considered for patient with impaired heart function.

Hereditary hearing loss (HL) is a heterogeneous and most common sensory neural disorder. At least, 76 genes have been reported in association with autosomal recessive nonsyndromic HL (ARNSHL). Herein, we subjected two patients with bilateral sensorineural HL in two distinct consanguineous Iranian families to figure out the underlying genetic factors. Physical and sensorineural examinations were performed on the patients. Imaging also was applied to unveil any abnormalities in anatomical structures of the middle and inner ear. In order to decipher the possible genetic causes of the verified GJB2-negative samples, the probands were subjected to whole-exome sequencing and, subsequently, Sanger sequencing was applied for variant confirmation. Clinical examinations showed ARNSHL in the patients. After doing whole exome sequencing, two novel variants were identified that were co-segregating with HL that were absent in 100 ethnically matched controls. In the first family, a novel homozygous variant, NM_138691.2 c.530T>C; p.(lle177Thr), in TMC1 gene co-segregated with prelingual ARNSHL. Fulvestrant cost In the second family, NM_022124.6 c.2334G>A; p.(Trp778*) was reported as a nonsense variant causing prelingual ARNSHL. These findings can, in turn, endorse how TMC1 and CDH23 screening is critical to detecting HL in Iranian patients. Identifying TMC1 and CDH23 pathogenic variants doubtlessly help in the detailed genotypic characterization of HL.

The majority of previous studies of the clinical outcome of video-assisted thoracoscopic surgery (VATS) versus open lobectomy for pathological N2 non-small cell lung cancer (pN2 NSCLC) have been single-center experiences with small patient numbers. The aim of this study was therefore to
