A new study published in Neurosurgery finds that surgery provides good functional outcomes and a high cure rate for patients with lower-grade arteriovenous malformations (AVMs) of the brain. The research evaluated 105 patients with AVMs from 2005 to 2012, concluding that treatment is recommended for appropriately selected patients.
Researchers found that rats' behavior changed according to waiting times, mimicking human actions. The neural basis was linked to the striatum, where neurons encoded time as a position within an interval, not absolute units.
A fruit-based micronutrient and fiber-dense supplement bar improved metabolism, reduced chronic inflammation, and initiated weight loss in overweight/obese individuals. The CHORI-bar's composition is complex and required years of clinical trials to develop.
Researchers used TACC's Lonestar4 supercomputer to simulate and analyze data for various vaccine trial designs. They found that a phased-rollout randomized controlled trial would provide better information about the effectiveness of an Ebola vaccine.
A new gene therapy treatment has shown significant clinical improvement in six patients with Wiskott-Aldrich Syndrome, a rare and complex immune disorder. The treatment involves correcting genetic anomalies in blood stem cells using a lentiviral vector, resulting in restored immune function and reduced symptoms.

A new variety of broccoli, enriched with glucoraphanin, has been shown to reduce blood LDL-cholesterol levels by an average of 6%. The compound is converted into sulphuraphane in the body, which activates genes that help balance metabolism and reduce cholesterol production.
A review of thousands of studies found that only a few dozen programs meet the scientific gold standard for reliability. Jenny Craig and Weight Watchers showed promise with participants losing more weight than non-participants in trials lasting 12 months or longer.
Therapeutic anti-cancer vaccines have been associated with a statistically significant increase in patient survival, but rarely have a noticeable effect on tumor growth. The study suggests that overall survival, rather than progression-free survival, should be the gold standard for evaluating cancer vaccine efficacy.

In intermediate-risk patients, the device showed encouraging results, with a reduced rate of major vascular complications and fewer instances of heart attacks and annular rupture.
The SAPIEN transcatheter heart valve is a feasible option for high-risk patients with severe aortic stenosis, but valve leakage remains a significant issue. At five years, death and stroke rates were equivalent to open-heart surgery, but rehospitalization rates and functional outcomes differed.
The HEART Pathway, a new protocol, helps emergency departments evaluate patients with acute chest pain more efficiently. It has been shown to reduce cardiac tests, early discharges, and hospital stays while maintaining patient safety.
Patients undergoing non-emergency cardiac surgery were given either a low or high haemoglobin threshold for transfusion, with the researchers finding that more patients died in the 'low' group. Health care costs and serious complications were similar in both groups, challenging prevailing guidelines.
Duke Medicine researchers found that only 13.4% of clinical trials reported findings within the required one-year window, with industry-sponsored trials reporting at 17%, while academic/non-NIH-funded trials reported at just 5.7%. The lack of transparency hampers progress and violates obligations to patients.
A new natural treatment for Alzheimer's disease, withanamides, is being developed by Michigan State University. The compound has shown to protect brain cells from damage caused by the rogue protein BAP, which is a common factor in Alzheimer's progression.
Researchers found that patients who received blood transfusions at a higher haemoglobin level had fewer serious complications and deaths after cardiac surgery. The study challenges current guidelines and health policy, suggesting that a more liberal approach to transfusion may be safer and more cost-effective
Researchers at UTHealth successfully enrolled patients from other hospitals into an acute stroke clinical trial using telemedicine. This breakthrough enables the study of stroke treatment on a larger scale, as it was previously limited to large centers with expertise in treating strokes quickly.

A clinical trial at UTHealth investigates the use of a physician-monitored app to encourage minority stroke patients to lose weight and manage risk factors. The study aims to close the racial disparities gap in stroke care, with patients randomized to usual care or the app group.
A new study found that consuming peanut-containing snacks from infancy can prevent peanut allergy in high-risk infants. In contrast, avoiding peanuts led to a higher risk of developing the allergy by age 5. The findings suggest a shift in advice for parents and healthcare providers to promote early consumption of allergenic foods.
Patients receiving fondaparinux had a lower risk of major bleeding events and death following a heart attack compared to those receiving low-molecular-weight heparin. This association was observed in both hospital settings and six months post-incident.
A clinical trial led by the University of Southern California has successfully implanted an ABI device in four children who were previously unable to hear. The device stimulates neurons directly at the human brainstem, bypassing the inner ear entirely and showing promising results in young children.
The HPV vaccine was highly effective against common cancer-causing human papillomaviruses beyond types 16 and 18. Young women vaccinated before sexual debut showed substantial protection against cervical abnormalities and precancerous cell transformations.

Researchers at USF are developing a new treatment for age-related hearing loss (ARHL), a neurodegenerative condition affecting 10% of the population. The Phase II clinical trial aims to investigate the therapeutic potential of modulating potassium channels in the brain.
The NELSON trial found that individuals with better health profiles and younger age were less likely to participate, but the study's findings remain relevant due to modest differences. The trial showed a higher mortality rate among eligible non-participants compared to participants.
A five-year follow-up study of patients with extreme obesity found that duodenal switch was more effective in reducing body weight than gastric bypass, but it came with a higher risk of complications. The study suggests that duodenal switch should be used with caution due to its adverse effects.
A recent study found that smartphone applications and wearable devices are generally accurate in tracking step counts, with minimal variation between devices. However, some wearables reported higher or lower counts than observed, highlighting the need for device accuracy assessment.
A new study published in JAMA found that smartphone apps are as accurate as wearable devices in tracking physical activity. The research used 10 top-selling smartphone apps and devices to compare their accuracy, with results showing smartphones were only slightly off from the observed step counts.
