Jan 31st, 2023 - Practice Essentials Protein S is a vitamin K–dependent anticoagulant protein that was first discovered in Seattle, Washington in 1979 and arbitrarily named after that city. The major function of protein S is as a cofactor to facilitate the action of activated protein C (APC) on its substrates, activated factor V (FVa) and activated factor VIII (FVIIIa). Protein S deficiency usually manifests cl...

The clinical and chest computed tomography imaging data of 47 asymptomatic carriers and 36 symptomatic COVID-19 patients were derived. All patients underwent 4-6 CT scans over a period of 2-5 days. The bulk of asymptomatic carriers who developed sympto...

Dec 1st, 2022 - HONG KONG (Reuters) - China will allow some people who test positive for COVID-19 to quarantine at home, among supplementary measures to be announced in coming days, two sources with knowledge of the matter told Reuters. Home isolation for the infected would be a significant change in China's quarantine protocols. Earlier this year, entire communities were locked down, sometimes for weeks, afte...

Oct 28th, 2022 - Since the advent of 2019 novel coronavirus (COVID-19), the coexistence between social stigma and depression symptoms (depression hereafter) in COVID-19 patients has been mentioned, but the mechanisms involved remains unclear. This study aimed to explore how the stigma affects depression during the mid-pandemic period. A cross-sectional survey using non-probability sampling was conducted among a...

Jul 22nd, 2022 - Community of Hope Health Clinic (CHHC), a free and charitable clinic in Shelby County, Alabama, developed a screening protocol to identify patients with asymptomatic COVID-19 with the goal of minimizing infection risk for other patients, health care providers, and staff. We sought to determine whether the use of the CHHC screening protocol identified asymptomatic carriers of SARS-CoV-2 before t...

Jul 12th, 2022 - Identification and isolation of contagious individuals along with quarantine of close contacts, is critical for slowing the spread of COVID-19. Large-scale testing in a surveillance or screening capacity for asymptomatic carriers of COVID-19 provides both data on viral spread and the follow-up ability to rapidly test individuals during suspected outbreaks. The COVID-19 early detection program a...

Jun 12th, 2022 - Controversies exist regarding the benefits and most appropriate approach for preprocedural coronavirus disease 2019 (COVID-19) testing (eg, rapid antigen test, polymerase chain reaction, or real-time polymerase chain reaction) for outpatients undergoing diagnostic and therapeutic procedures, such as GI endoscopy, to prevent COVID-19 infections among staff. Guidelines for protecting healthcare w...

May 28th, 2022 - Covid-19 is a new virus of the Coronaviridae family that is now spreading worldwide. Therefore, disseminating information about patients with the virus can help identify the virus, pathogenesis, and find treatments. The current study aimed to review the new coronavirus (Covid-19). To reach this aim, we searched keywords containing Covid-19, coronavirus, respiratory infection, epidemiology in Pu...

May 24th, 2022 - The clinical manifestations of COVID-19 are different, which can be attributed to asymptomatic carriers, acute respiratory disease and pneumonia with different severities. The aim of this study was to compare the epidemiological characteristics and outcomes of COVID-19 in patients with clinical symptoms versus asymptomatic patients. In this retrospective cohort study, the epidemiological charac...

May 15th, 2022 - The transmission of SARS-CoV-2 occurs through direct contact (person to person) and indirect contact by means of objects and surfaces contaminated by secretions from individuals with COVID-19 or asymptomatic carriers. In this study, we evaluated the presence of SARS-CoV-2 RNA on surfaces made of different materials located in university environments frequented by students and staff involved in ...

Mar 7th, 2022 - COVID-19 pandemic spreads worldwide, with more than 100 million positive cases and more than 2 million deaths. From the beginning of the COVID-19 pandemic, several otolaryngologists described many cases of a sudden loss of smell (anosmia) associated with the disease with or without additional symptoms. Anosmia is often the first and sometimes the only sign in the asymptomatic carriers of COVID-...

Feb 18th, 2022 - Pooled data from 2352 hospitalized coronavirus disease 2019 (COVID-19) patients with viral RNA in feces across 46 studies were analyzed and the pooled prevalence of fecal RNA was 46.8% (95% confidence interval [CI]: 0.383-0.554). The pooled analysis showed that the occurrence of total gastrointestinal (GI) symptoms was 28.5% (95% CI: 0.125-0.44) in COVID-19 patients with fecal RNA, that of both...
