Poor night’s sleep can trigger atrial fibrillation the next day

A new study by UC San Francisco found that poor sleep is significantly associated with a 15% greater risk of experiencing atrial fibrillation the next day. The researchers suggest strategies like going to bed at a reasonable time, avoiding alcohol and caffeine before bedtime, and exercising regularly to improve general sleep quality.

New method for detecting blood circulation problems in brain capillaries

Researchers developed a new imaging technique using Bessel beam two-photon microscopy to detect stalling in brain capillaries, which can indicate acute neurological issues. The approach generates clear images of all capillaries every two seconds, providing better temporal resolution and enabling the detection of short stalling events.

CHOP and Penn Medicine researchers develop “in vivo” RNA-based gene editing model for blood disorders

CHOP and Penn Medicine researchers have developed a proof-of-concept model for delivering gene editing tools directly into diseased blood cells within the body. This approach aims to reduce costs and increase access to gene therapies for blood disorders, which currently require chemotherapy and stem cell transplants.

Antibody treatment prevents graft versus host disease, a major bone marrow transplant complication, in advanced preclinical tests

Researchers have developed an experimental antibody treatment that largely prevented graft versus host disease in the intestines, without causing broad immune suppression. The treatment blocked donor T-cell attack and increased survival rates in preclinical models.

Cause of leukemia in trisomy 21

Children with Down syndrome are highly vulnerable to developing aggressive leukaemia due to a defect in the RUNX1 gene, which regulates blood cell formation. Researchers have identified a specific variant of the gene that promotes leukaemia development and discovered potential therapeutic approaches to correct this malfunction.

Liquid biopsies can detect which cancer patients may be at higher risk of developing additional blood cancers

Researchers found that liquid biopsies can detect clonal haematopoiesis, a condition placing patients at higher risk of developing myelodysplastic syndrome or acute myeloid leukaemia. The study suggests that these patients should be referred for further evaluation to uncover actual risk and identify potential diagnostic pathways.

Cancer patients treated with immunotherapy can safely receive mRNA COVID-19 vaccines, according to JNCCN study

Researchers analyzed 408 patients receiving immune checkpoint inhibitor therapy and found no increased risk of side effects from receiving both immunotherapy and the vaccine. The study supports NCCN's recommendations for COVID-19 vaccination in people with cancer, citing strong protection against severe COVID-19 for all variants.

Microscopic blood vessel disease in the brain’s white matter associated with worse cognition in Alzheimer’s

Researchers found that microscopic blood vessel disease in the brain's white matter is associated with worse cognitive function and memory deficits in individuals with Alzheimer's. Lifestyle changes such as reducing hypertension, obesity, diabetes, and inactivity may help prevent or slow disease progression.

Chemotherapy drugs from “rogue” online pharmacies could endanger leukemia patients, suggests research in JNCCN

A study found that a majority of online pharmacies selling imatinib, a chronic myeloid leukemia therapy, are uncertified and operate unsafely. Patients may face risks of nonadherence, treatment failures, and adverse events if they use these pharmacies.
