Heart disease-protective diabetes drug not used equitably, study finds

A recent study found significant inequities in the use of GLP-1 receptor agonists (GLP-1 RA), a medication typically used for treating diabetes, among different racial and ethnic groups. The study, published in JAMA Health Forum, showed that Black patients were 19% less likely to have a GLP-1 RA prescription compared to white patients.

The inaugural WHO classification of childhood tumors will provide a unified, updated resource for the diagnosis of pediatric cancers

The inaugural WHO classification of childhood tumors presents a single, updated compendium of all tumor entities in childhood or adolescence, divided by organ sites. This classification incorporates traditional morphology, immunohistochemistry, and molecular characteristics to provide essential criteria for definition of tumor types.

Critically ill COVID-19 patients with acute kidney injury more likely to die than those with pre-existing chronic kidney disease

A new study presented at Euroanaesthesia found that critically ill COVID-19 patients with acute kidney injury are more likely to die in the ICU than those with pre-existing chronic kidney disease. The study also showed that dialysis treatment has little impact on survival rates for these patients.

Muslim comedy tackles popular misconceptions using humor and empathy, new Concordia research shows

A new study by Concordia PhD student Lamiae Aidi examines how Muslim stand-up comedians use incongruity, performativity, and everydayness to demystify their community. By sharing personal experiences and poking fun at stereotypes, these comedians aim to create awareness around problems of discrimination and misunderstandings.

Series of preclinical studies supports the Army’s pan-coronavirus vaccine development strategy

Recent preclinical study results demonstrate the Spike Ferritin Nanoparticle (SpFN) COVID-19 vaccine developed by WRAIR elicits potent immune responses and offers broad protection against SARS-CoV-2 variants and other coronaviruses. The SpFN vaccine uses a ferritin platform to present multiple copies of the coronavirus spike protein, i...

Shark antibody-like proteins neutralize COVID-19 virus, help prepare for future coronaviruses

Researchers have discovered unique antibody-like proteins from sharks that can prevent the COVID-19 virus and its variants from infecting human cells. These shark-derived protein 'VNARs' are a promising new tool in the fight against SARS-CoV-2, with potential applications for future coronavirus outbreaks.

Cough or fever first? Study analyzes order of COVID-19 symptoms

A new study published in PLOS Computational Biology found that the order of COVID-19 symptoms varies depending on the SARS-CoV-2 variant. In the USA, cough was most likely to be the first symptom, while fever and diarrhea were more common third symptoms.

New research may identify infants who face high asthma risk after viral lung infections

Researchers found that the risk of developing asthma in infants depends on a complex interplay among the infecting virus, airway microbial composition and function, and the infant's immune response. Infants with distinct metatranscriptome profiles had unique risks of developing asthma by age five.

Omicron may cause 100,000 cancelled operations in England this winter

A new study warns that Omicron could lead to 100,273 fewer elective operations performed over the three winter months due to increased hospital admissions and COVID-19 patients. The model used NHS England data from September 2020 to July 2021 to project elective surgery activity based on the number of COVID-19 patients in hospital.

For IBS, specific diets are less important than expected

A new study found that a specific type of carbohydrate called ‘fodmaps’ can aggravate intestinal problems, but its impact is not as significant as previously believed. IBS symptoms were found to be influenced more by psychological factors and individual differences in metabolism and intestinal flora.

Visceral surgery: Gut bacteria aggravate adhesions after abdominal surgery

Researchers have discovered that intestinal bacteria can lead to more severe adhesions after abdominal surgery. The study found that mesothelial cells and EGFR signaling play a crucial role in the formation of these adhesions. The findings suggest that targeting EGFR may be a potential approach to reducing adhesion risk.
