Primary care practices use 4 complementary methods to identify high-risk patients

Four primary methods are used by primary care practices to risk stratify patient populations: practice-developed algorithm, AAFP clinical algorithm, payer claims/electronic health record, and clinical intuition. Practices that developed their own algorithm identify more high-risk patients than those using other methods.

Scientists use mismatch in telescopic data to get a handle on quasars and their 'tails'

Researchers have gained a better understanding of the structure of hot jets and accretion disks surrounding black holes at the center of galaxies. They compared data from radio interferometry and Gaia space observatory, discovering discrepancies in object positions that revealed bright jets emitting visible light in many quasars.

Adults with intellectual disabilities are at high risk of preventable emergency admissions

Adults with intellectual disabilities have a nearly threefold higher rate of emergency hospitalizations and five times more preventable admissions than their matched controls. The most common ACSCs resulting in admission are convulsions/epilepsy, lower respiratory tract infection, and urinary tract infection.

US public backs carbon tax, and spending revenue on renewables

A new study found that the majority of Americans support a carbon tax, with 80% wanting revenue used for clean energy development and infrastructure improvements. The average American household is willing to pay $177 per year in carbon tax, generating around $22 billion for investments in renewable energy and infrastructure.

Therapy proves effective in subgroup of COPD patients

A new antibody treatment has been shown to reduce the rate of exacerbations by nearly 20% in patients with a subgroup of treatment-resistant chronic obstructive pulmonary disease (COPD). The study found that patients with high eosinophil counts benefited more from the treatment, indicating a potential biomarker for the disease.

'Superbug' bacteria gang up on us, fueled by antibiotic use, nursing home study suggests

Researchers found that 40% of nursing home patients had multiple multidrug-resistant organisms living on their bodies, increasing the risk of urinary tract infections. The study suggests a complex network of interactions among bacteria and antibiotics, highlighting the need for more targeted treatment approaches.
