Abstract

Roux-en-Y gastric bypass (RYGB) is the most common bariatric procedure worldwide. There are few studies investigating how early return to solid food affects complications. The aim of this study was to explore how oral intake was resumed in RYGB patients and how the postoperative food regimen affects outcomes, such as complications and length of stay. Retrospective nationwide registry study. The Scandinavian Obesity Surgery Registry included prospective data from RYGB patients operated in 2009 to 2014. A questionnaire assessed the postoperative reintroduction of solid food applied at each bariatric center. The postoperative regimen was established in 23,589 patients. Outcomes were recorded at 30-day follow-up according to the standard Scandinavian Obesity Surgery Registry routine. Nine percent of patients (n = 2074) returned to solid food within the first week after surgery. Most commonly solid food was resumed in week 4 (37%, n = 8659). Median length of stay was 2 days for all. Of all, 2.8% suffered from a severe complication (>Clavien-Dindo 3a). After adjusting for the annual volume of procedures at hospitals, there was no correlation that the timing of solid food affected complication rates. The odds ratio for a severe compli...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.
