A single protein that helps drive responses to touch, temperature, pain and itch could offer a new drug target

A light brush, a hot surface and an irritating itch all activate different sensory pathways, yet researchers have determined that, in mice, these otherwise distinct responses share a molecular helper. A team led by Bailong Xiao at Tsinghua University found that removing the protein CRELD1 weakened the animals' reactions to touch, heat, cold, painful pressure and itch. But how can one protein influence so many different sensations?

Medicare spending rises after private equity buys hospices

A study of for-profit hospices acquired by private equity firms found that Medicare spending rose by 5.9% per hospice stay after acquisition, compared with similar for-profit hospices that weren't acquired. The increase was driven mainly by longer stays, with the average length of stay rising by 6.3 days. This was likely related to shifts toward patients who use less daily care, including a significant increase in the share of patients with dementia, consistent with a larger share of patients discharged from hospice alive.

Subtype-specific mutations drive relapse risk in most common childhood leukemia

Some cases of the most common childhood cancer, B-cell acute lymphoblastic leukemia (B-ALL), return after treatment—and genetic changes present from the start may help explain why. Scientists at St. Jude Children's Research Hospital and Seattle Children's Hospital, in collaboration with the Children's Oncology Group, found that mutations in a patient's original tumor can be associated with relapse risk, and that these changes differ by leukemia subtype. The findings, published in Blood, could help researchers better estimate and adjust for relapse risk before treatment begins.

Tumor index can identify breast cancer patients' drug response

Researchers at The Hong Kong Polytechnic University (PolyU) have developed an imaging biomarker, the Tumour Heterogeneity Index (THI), which enables noninvasive assessment of breast cancer patients' response to AKT inhibitors before treatment, helping clinicians identify patients most likely to benefit from therapy. The study found that patients with a high THI achieved an estimated pathological complete response (pCR) rate of 56.1%, significantly higher than that of patients with a low THI. The technology could help patients receive the most appropriate treatment at an earlier stage, reduce unnecessary side effects and enable clinicians to better tailor treatment strategies to individual patients.

Long COVID Patients Frustrated That Federal Research Hasn't Found New Treatments

This is a MedPage Today story. Erica Hayes, 40, has not felt healthy since November 2020 when she first fell ill with COVID. Hayes is too sick to work, so she has spent much of the last 4 years sitting on her beige couch, often curled up under an electric blanket. "My blood flow now sucks, so my hands and my feet are freezing. Even if I'm sweating, my toes are cold," said Hayes, who lives in Western Pennsylvania. She misses feeling well enough to play with her 9-year-old son or attend her 17-year-old son's baseball games. Along with claiming the lives of 1.2 million Americans, the COVID-19 pandemic has been described as a mass disabling event. Hayes is one of millions of Americans who suffer from long COVID. Depending on the patient, the condition can rob someone of energy, scramble the autonomic nervous system, or fog their memory, among many other symptoms. In addition to the brain fog and chronic fatigue, Hayes' constellation of symptoms includes frequent hives and migraines....
