To quantify the association between insomnia or poor sleep with objective short duration and incident cardiovascular disease (CVD) mortality in general population.We conducted a time-to-event analysis of Sleep Heart Health Study data. Questionnaires at-home polysomnography (PSG) were performed 1994 1998. Participants followed for median 11.4 years (Q1-Q3, 8.8-12.4 years) until death last contact. The primary exposure was defined as follows: difficulty falling asleep, returning to sleep,...

Several vaccines are now available under emergency use authorization in the United States and have demonstrated efficacy against symptomatic COVID-19. Vaccine impact on asymptomatic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is largely unknown.

Objectives Postoperative atrial fibrillation (AF) following coronary artery bypass graft surgery (CABG) is significantly associated with reduced survival, but poor characterisation and inconsistent definitions present barriers to developing effective prophylaxis management. We sought address this knowledge gap. Methods From 2002 2010, 11 239 consecutive patients without AF underwent isolated CABG at five sites. Clinical data collected for the Society of Thoracic Surgeons (STS) Database were...

To determine the incidence of retinoblastoma in United States from 1973 to 2012 (40 years) and characterize 5-year overall survival rate included patients.Cases were derived Surveillance, Epidemiology, End Results (SEER) Program (National Cancer Institute, Rockville, MD). Incidence rates calculated using U.S. Census Bureau data as standard population, trends over time determined chi-square test. Hazard ratios with a 95% confidence interval (CI) estimated for variables associated mortality...

Aims:The aim of this study was to validate the recently developed STS/ACC TAVR in-hospital mortality risk score for predicting after transcatheter aotic valve implantation (TAVI) and compare its ability predict 30-day with that four other established models (EuroSCORE I, EuroSCORE II, STS-PROM, German AV Score). Methods results:The cohort included 946 consecutive patients who underwent TAVI between 2013 2015.Each five scores fitted as a continuous linear variable into logistic regression...

Objective Female sex is considered a risk factor for adverse outcomes following isolated coronary artery bypass graft (CABG) surgery. We assessed the association between and short-term mortality CABG, estimated ‘excess’ deaths occurring in women. Methods Short-term was investigated 13 327 consecutive CABG patients North Texas January 2008 December 2012. The mortality, excess among women were via propensity-adjusted (by Society of Thoracic Surgeons-recognised factors) generalised estimating...

Abstract We characterized coronavirus disease 2019 (COVID-19) breakthrough cases admitted to a single center in Florida. With the emergence of delta variant, an increased number hospitalizations was seen due infections. These patients were older and more likely have comorbidities. Preventive measures should be maintained even after vaccination.

Abstract Diagnosis codes are used to study SARS-CoV2 infections and COVID-19 hospitalizations in administrative electronic health record (EHR) data. Using EHR data (April 2020–March 2021) at the Yale-New Haven Health System three hospital systems of Mayo Clinic, computable phenotype definitions based on ICD-10 diagnosis (U07.1) were evaluated against positive SARS-CoV-2 PCR or antigen tests. We included 69,423 patients Yale 75,748 Clinic with either a code test. The precision recall for test...

The availability of large state and federally run administrative health-care databases provides potentially comprehensive population-wide information that can dramatically impact both medical health-policy decision-making. Specific opportunities important limitations exist with all based on what is collected how reliably specific data elements are reported. Access to patient identifiable-level be critical for certain long-term outcome studies but difficult (although not impossible) due...

New-onset atrial fibrillation (AF) after coronary artery bypass graft surgery (CABG) is associated with increased morbidity and poorer long-term survival. Although many studies show differences in outcome women versus men CABG, little known about the sex-specific incidence characteristics of post-CABG AF.Overall, 11 236 consecutive patients without preoperative AF underwent isolated CABG from 2002 to 2010 at 4 US academic medical centers 1 high-volume specialty cardiac hospital. Data...

Due to increasing clinical experience with transcatheter aortic valve implantation (TAVI) procedures, sophisticated imaging and advanced device technology, TAVI complication rates are low; however, patients requiring conversion surgery confronted an increased mortality risk. In this retrospective study, we evaluated the predictors for outcomes of these patients.We analysed records all undergoing in our centre from 2011 2016 focused on cases that required sternotomy. We investigated reasons...

The emergence of SARS-CoV-2 variants concern has led to significant phenotypical changes in transmissibility, virulence, and public health measures. Our study used clinical data compare characteristics between a Delta variant wave pre-Delta hospitalized patients.This single-center retrospective defined as an increasing number COVID-19 hospitalizations, which peaked later decreased. Data from the United States Department Health Human Services were identify waves' primary variant. Wave 1...
