A pill for obesity?

Researchers at Harvard University have developed a system using human stem cells to screen for compounds that can turn white, or 'bad', fat cells into brown, or 'good' fat cells. They have identified two compounds that can accomplish this in human cells, taking the first step towards a potential pill for obesity treatment.

Two papers in Health Affairs expose gaps in health coverage for children, recommend solutions

Two Health Affairs papers expose gaps in health coverage for children and recommend solutions. The studies focus on the Affordable Care Act's essential health benefit standard, which has resulted in a state-by-state patchwork of coverage with significant exclusions for children with developmental disabilities.

High level engagement in comment sections can curb internet trolling

A recent study found that having a journalist engage with commenters can reduce incivility and increase the use of evidence in comments. The researchers partnered with a local television news station and conducted an experiment using its Facebook community, resulting in a statistically significant effect on the tone of the comments.

Confounding factors contribute to unexpected results of trial of renal denervation

A new analysis of the SYMPLICITY HTN-3 trial reveals that variations in renal denervation procedure performance and patient medication changes significantly impacted blood pressure reduction outcomes. The study suggests that a higher number of ablations and specific procedural patterns may be key to achieving effective denervation.

Is natural gas a 'bridge' to a hotter future?

Researchers found that natural gas power plants are more efficient than coal plants, producing less warming in the long term. However, significant methane leakage can offset this benefit, making them comparable to coal plants in terms of climate impact. To mitigate this, carbon capture and storage methods may be necessary.

Pricing for new drugs lacks transparency

Market-access agreements for anti-cancer drugs lack transparency, leading to higher prices for patients in small and low-income countries. The financial arrangements between pharmaceutical manufacturers and health systems are kept confidential, making it difficult for these countries to negotiate lower prices.

Researchers at Mainz University explore new approach for treating Alzheimer's disease

Researchers at Mainz University have discovered that a psoriasis medication may be effective in treating Alzheimer's disease by stimulating the activity of the enzyme ADAM10, which could lead to reduced accumulation of Alzheimer's plaques. The medication was well-tolerated and showed promise in enhancing learning and memory capacity.

New study identifies first gene associated with familial glioma

Researchers have identified a gene associated with familial glioma, suggesting that certain individuals may be genetically predisposed to the disease. The POT1 gene mutation is linked to lower-grade oligodendroglioma, which is more sensitive to radiation therapy, and raises hopes for improved treatments and preventive strategies.

Malnutrition is predictor of long-term survival in patients undergoing Whipple procedure

A new study finds that malnutrition is an independent predictor of long-term survival in geriatric patients undergoing the Whipple procedure. Geriatric patients with preoperative severe nutritional risk had significantly decreased long-term survival, while those without SNR had a seven-year survival rate of 84 percent.
