Brain circuitry shaped by competition for space as well as genetics

A new computer modelling study suggests that simple interactions between nerve cells contribute to the development of complex brain circuits, making a precise genetic blueprint unnecessary. The findings help answer how the brain wires itself during development and may inform new ways to treat conditions that disrupt brain circuits.

Doctors get plenty of advice on starting treatment; this could help them know when to stop

A new study provides a framework for guideline developers to offer specific guidance on right-sizing care, including when to start and stop treatments or screening. The recommendations are tailored for adult primary care and aim to reduce unnecessary testing and treatment, improving patient outcomes and quality of life.

Ellipsys system offers greater patient eligibility and reduced time to dialysis

The new study found that both Ellipsys and WavelinQ systems enabled patients to start dialysis sooner compared to surgery, offering significant quality-of-life benefits. The Ellipsys System demonstrated higher technical success rate and more durable access, with 82% of Ellipsys fistulas still functional at 12 months.

Mount Sinai study finds COVID patients were most commonly readmitted to hospital for respiratory complications

A Mount Sinai study found that COVID patients were most commonly readmitted to the hospital for respiratory distress, with chronic obstructive pulmonary disease and hypertension being key comorbidities. The study also showed that these patients had shorter hospital stays and lower rates of anticoagulation treatment.

Elevated "hunger" hormone leaves trauma-exposed teens at higher risk for PTSD

A recent study published in JAMA Network Open found that trauma-exposed adolescents with moderately elevated acyl-ghrelin hormone levels are almost eight times more likely to develop post-traumatic stress disorder (PTSD). The study also suggests that lower acyl-ghrelin levels may reduce the risk and severity of subsequent PTSD.

Mount Sinai researchers identify master regulator genes of asthma

Researchers have identified master regulator genes that causally regulate key biological processes underlying asthma. These genes provide a novel path forward for uncovering mechanisms and developing novel therapies for asthma. The study also identified nasal gene signatures for mild, moderate, and severe persistent asthma.

Researchers identify better classification system for adult idiopathic scoliosis

Researchers have designed a new X-ray classification system for adult idiopathic scoliosis, providing a more universal and standard assessment of the condition. The three-component method maintains existing curve types while introducing assessments of global alignment and lumbosacral curve, improving treatment options for older patients.

Gluten in wheat: What has changed during 120 years of breeding?

A study by the Leibniz-Institute for Food Systems Biology found that modern wheat varieties contain slightly less protein than older varieties, while maintaining a consistent gluten content. The researchers also discovered that environmental conditions, such as precipitation, played a significant role in shaping protein composition.

STRIDE study tests ways to prevent injuries from falls

A new study by Yale University researchers found that a nurse-delivered strategy to prevent falls among older adults reduced the rate of first adjudicated serious fall injury by nearly 10%. The approach also produced significant reductions in self-reported injuries, highlighting its potential in reducing fall-related harm.

A scientific measure of dog years

Researchers found a new formula that better matches canine-human life stages, with an 8-week-old dog equivalent to a 9-month-old baby. The study also identified developmental genes that drive aging and created an age-measuring clock for different species.

Researchers identify distinct subtypes of polycystic ovary syndrome with novel genetic associations

Researchers identified reproductive and metabolic subtypes of PCOS associated with novel gene regions, promising to transform understanding of the disorder. The study used clustering of clinical, metabolic, and hormonal data from women with PCOS, revealing two distinct subtypes with different genetic architectures.

A coordinated COVID-19 response helped western Washington state "flatten the curve"

The region's successful response was attributed to six key factors: early communication and coordination, regional coordination and situational awareness, rapid testing development, proactive management of long-term care facilities, effective physical distancing in the community, and partnership with local organizations. This coordinat...
