Surgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global priority not fully understood. We quantified burden SSI after gastrointestinal surgery in countries all parts world.
Extrapulmonary disease has been observed in patients with coronavirus 2019 (COVID-19).1–3 We describe here the gastrointestinal (GI) complications of severe COVID-19 admitted to intensive care unit (ICU) at Massachusetts General Hospital between March 13 and April 12, 2020. During this time period, 141 were ICU acute respiratory syndrome 2 infection confirmed by reverse-transcriptase–polymerase-chain-reaction testing. The median (interquartile range) age was 57 (47, 70) years, 65% them men,...
Hydroxychloroquine, a drug commonly used in the treatment of rheumatoid arthritis, has received much negative publicity for adverse events associated with its authorisation emergency use to treat patients COVID-19 pneumonia. We studied safety hydroxychloroquine, alone and combination azithromycin, determine risk routine care arthritis.
BackgroundCongenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital fatal without timely access to neonatal surgical care, but few studies have been done on these conditions low-income and middle-income countries (LMICs). We compared outcomes seven most common low-income, middle-income, high-income globally, identified factors associated with mortality.MethodsWe did a multicentre, international prospective cohort...
ABSTRACT Background Hydroxychloroquine has recently received Emergency Use Authorization by the FDA and is currently prescribed in combination with azithromycin for COVID-19 pneumonia. We studied safety of hydroxychloroquine, alone azithromycin. Methods New user cohort studies were conducted including 16 severe adverse events (SAEs). Rheumatoid arthritis patients aged 18+ initiating hydroxychloroquine compared to those sulfasalazine followed up over 30 days. Self-controlled case series...

There have been reports persistent symptoms after confirmed infections on patients even three months initial recovery. While some these documented follow-ups clinical records, or participate in longitudinal surveys, datasets are usually not publicly available standardized perform analyses them. Therefore, a need use additional data sources...
Routinely collected real world data (RWD) have great utility in aiding the novel coronavirus disease (COVID-19) pandemic response. Here we present international Observational Health Data Sciences and Informatics (OHDSI) Characterizing Associated Risks Your Baseline Disease In SARS-COV-2 (CHARYBDIS) framework for standardisation analysis of COVID-19 RWD.
Abstract The ongoing Israeli military assault on Gaza has caused a devastating collapse of healthcare infrastructure, resulting in an unprecedented surge infectious diseases. destruction sanitation systems, restrictions medical supplies, and displacement civilians have created environment conducive to the rapid spread waterborne, vector‐borne, antibiotic‐resistant infections. This paper draws from insights local Palestinian workers recent missions conducted by FAJR Scientific, Palestine...
Abstract Introduction Tranexamic acid (TXA) is an antifibrinolytic agent primarily used to prevent bleeding. In recent years, multiple studies have investigated its use in burn surgery. While some systematic reviews and meta-analyses been conducted, none comprehensively reviewed all available literature on this topic a way that effectively translates clinical application. A thorough well-organized review needed clarify current findings complex issue. Methods We conducted following PRISMA...
