Study finds long-term outcomes of weight loss surgery in children, adolescents with severe obesity

Results from a 10-year study of children and adolescents who underwent a common weight loss operation to treat severe obesity show they safely have long-lasting major weight loss and improvement of their obesity-related medical problems without stunting their growth in height. The study, involving the longest known follow-up of pediatric patients after laparoscopic sleeve gastrectomy, is published online by the Journal of the American College of Surgeons ahead of print.

Infections impact blood vessel repair within the meninges following TBI or other cerebrovascular injuries

Viral Infection Slows Blood Vessel Repair After TBI: Seven days after mTBI, the blood vessels (stained in red) in the tissues around the brain are not completely repaired. A marker for intact vessels was used (labeled in green) to distinguish fully functional blood vessels (yellow) from ones that are still damaged (red).McGavern Lab, NINDS

Melanomas that metastasize to the adrenal gland are resistant to checkpoint inhibitors

Recent advances in immunotherapy have allowed doctors at the University of Colorado Cancer Center to more effectively treat melanomas that spread to other parts of the body. Immunotherapy drugs such as checkpoint inhibitors, which are commonly used to treat melanomas, work to strengthen a patient's immune system so that it can prevent a tumor from "turning off" the ability of the immune system to fight it.

Researchers identify potential approach to eliminate race from equations to estimate kidney function

Researchers have identified an approach to remove race from equations used to estimate a person's kidney function. These equations have been criticized for potentially perpetuating racial health disparities. The findings, reported September 23 in the New England Journal of Medicine, are expected to inform National Kidney Foundation–American Society of Nephrology Task Force guidelines on evaluating kidney function.

Human milk antibodies elicited by vaccination show reduced activity against SARS-CoV-2 VoCs

In a study recently published on the medRxiv* preprint server, scientists from Singapore have assessed the levels of IgA-specific anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies in the breast milk of women recently immunized with the second dose of an mRNA-based coronavirus disease 2019 (COVID-19) vaccine.

May-Thurner anatomy common in patients with CTEPH, new study shows

Like highways, roads, and side streets, blood vessels in the human body come in different sizes, with a range of traffic-carrying capacities. These differences are critical to facilitating blood flow through tissues.

New mutations enable gliomas to resist proven treatment, study shows

About one-third of all brain tumors are gliomas, cancerous growths that originate in the glial cells that surround and support neurons in the brain. The prognosis for patients with gliomas is not good, with the average survival time being 12-18 months.

Johns Hopkins Medicine mathematical model to play major role in ending HIV nationwide

A new Johns Hopkins Medicine mathematical model to predict how the human immunodeficiency virus (HIV) spreads in urban areas will play a major role in a federal initiative aiming to reduce the incidence of HIV infections in the United States by 90% between 2020 and 2030.

Using air filtration to remove airborne SARS-CoV-2 and other microbial aerosols in COVID wards

University of Cambridge researchers conducted a study in two repurposed COVID-19 units in Addenbrooke’s Hospital, Cambridge, UK, between January and February 2021. During this time, the alpha variant (lineage B1.1.7) accounted for >80% of the circulating SARS-CoV-2. This study, posted to the medRxiv* preprint server, aimed to provide evidence of the removal of SARS-CoV-2 and microbial bioaerosols using portable air filters with UV sterilization.
