Introduction: Numerous case series have reported on the baseline characteristics and inhospital mortality of patients with COVID-19, however, these studies included patients localized in a specific geographic region. The purpose of our study was to identify differences in the clinical characteristics and the in-hospital mortality of patients with a laboratory-confirmed diagnosis of COVID-19 internationally. Methods: A comprehensive search of all published literature on adult patients with laboratory-confirmed diagnosis of COVID-19 that reported on the clinical characteristics and inhospital mortality was performed. Groups were compared using a Chi-square test with Yates correction of continuity. A two-tailed p value of less than 0.05 was considered as statistically significant. Results: After screening 516 studies across the globe, 43 studies from 12 countries were included in our final analysis. Patients with COVID-19 in America and Europe were older compared to their Asian counterparts. Europe had the highest percentage of male patients. American and European patients had a higher incidence of co-morbid conditions (p \ 0.05 for all variables). In-hospital mortality was significantly higher in America (22.23%) and Europe (22.9%) compared to Asia (12.65%) (p \ 0.0001), but no difference was seen when compared with each other (p = 0.49). Conclusions: There is a significant variation in the clinical characteristics in patients diagnosed with COVID-19 across the globe. In-hospital mortality is similar between America and Europe, but considerably higher than Asia.
Stroke in young poses a major health problem. Thrombophilic factors have been implicated in 4-8% of the young strokes worldwide. Protein S deficiency is a rare cause of recurrent ischemic stroke in young population. Only a few sporadic cases have been described in the literature. We are reporting a case of protein S deficiency-related recurrent ischemic stroke in a 16-year-old girl. Early diagnosis and targeted approach can help such patients to prevent recurrent thrombotic episodes.
Objectives: To compare outcomes in Sapien 3 Ultra (S3U) transcatheter aortic valve replacement (TAVR) with extreme annular undersizing (EAU) versus nominal annular sizing (NAS).
Background:The Edwards S3U valve has reduced paravalvular leak (PVL) in TAVR but outcomes remain unknown in extremely undersized anatomy. Implanting a smaller S3U valve may facilitate future redo-TAVR but risk compromising hemodynamics.Methods: From December 2019 to July 2021, 366 patients with native aortic stenosis underwent S3U TAVR. Patients with EAU (annular areas >430 mm 2 for 23 mm or >546 mm 2 for 26 mm) were compared to NAS (338-430 mm 2 for 23 mm or 430-546 mm 2 for 26 mm). In-hospital and 30-day outcomes, and redo-TAVR feasibility were determined.Results: There were 79 (21.6%) EAU patients, with more bicuspid (p = 0.0014) and ≥moderate annular/left ventricular outflow tract calcification (p < 0.001). The EAU group had less annular oversizing than NAS group (23 mm: −8.2 ± 2.6% vs. 4.0 ± 7.0%, p < 0.001; 26 mm: −8.9 ± 2.2% vs. 6.7 ± 6.9%, p < 0.001), more balloon overfilling (71.3% vs. 11.6%, p < 0.001), and postdilatation (15.0% vs. 5.8%, p = 0.016). No differences were found in in-hospital or 30-day mortality and stroke (p > 0.05). Mild PVL (13.4% EAU vs. 11.5% NAS, p = 0.56) and mean gradients (23 mm: 13.0 ± 4.5 vs. 14.1 ± 5.4 mmHg, p = 0.40; 26 mm: 11.4 ± 4.1 vs. 11.5 ± 3.9 mmHg, p = 1.0) were similar at 30 days. Had the EAU group undergone NAS with the larger Sapien 3/S3U, by computed tomography analysis simulating 80:20 or 90:10 target implant depth, 33.3%-60.9% (vs. 4.3%-23.2%) would not be feasible for redo-TAVR due to high risk of coronary obstruction.
There was 20% increase in STEMI every year. Younger patients are least likely to receive primary PCI or tenecteplase. 1 in 8 patients of STEMI did not receive any form of reperfusion therapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
