Abstract

Reports from high-quality healthcare systems have shown that active surveillance and management of factors associated with surgical site infection (SSI) decreased the incidence and improved overall outcomes. This study aimed to appraise the incidence trend of SSIs during the 10-year period between 2007 and 2016 in a university hospital in a middle-income country, focusing on six high-risk and high-volume procedures. The study also examined factors associated with SSIs and their impact on surgical outcomes. A total of 10,139 procedures in 9,661 cases were reviewed. The overall incidence of SSI was 2.98%. The incidence increased substantially with increasing risk score according to the National Nosocomial Infection Surveillance (NNIS) system risk score. The incidence trend decreased over time during the 10-year period studied. The procedures with the highest SSI incidence were craniotomy, colonic surgery, and cholecystectomy, which were also the three procedures that had standardized infection ratios (SIR) higher than 1.0 in all risk score categories. Univariable analysis found that diabetes mellitus was the only risk factor associated with SSI (odds ratio [OR] 1.81, 95% confidence interval [CI] 1.2-2.73). The majority of the pos...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
