A meta-analysis of randomized clinical trials found that endovascular therapy improved functional outcomes and higher rates of independence at 90 days, but no significant difference in symptomatic intracranial hemorrhage or all-cause mortality. The study included data from 8 trials involving 2,423 patients with acute ischemic stroke.
Researchers from Brigham and Women's Hospital found that low-fat interventions were no more successful than higher-fat interventions in achieving and maintaining weight loss for periods longer than one year. Low-carbohydrate weight loss interventions resulted in greater weight loss compared to low-fat diets.
A follow-up study found that cognitive behavioural therapy (CBT) and graded exercise therapy (GET) improved fatigue and physical functioning in patients with Chronic Fatigue Syndrome, maintaining these improvements over time. The treatments also reduced the likelihood of seeking additional therapy.

Researchers found that degenerating neurons in patients with Alzheimer's disease responded to gene therapy treatment by showing heightened growth, axonal sprouting, and activation of functional markers. The study suggests that nerve growth factor is safe over extended periods and merits continued testing as a potential AD treatment.
A new MRI study found that having the opportunity to learn from failure can turn it into a positive experience. The study showed that certain circumstances can prompt the brain's reward mechanism instead of avoidance learning, leading to improved understanding and behavior.
A review of survey data from over 300 obese participants found those who rated their primary care doctor's support as helpful lost an average of 11 pounds, compared to just 5 pounds for those with low-rated support. High-quality patient-doctor relationships are linked to better adherence and weight loss outcomes.
Doctors at Ohio State University Wexner Medical Center have successfully implanted lab-grown cartilage into a patient's knee, offering a potential long-term solution for patients with knee injuries. The implant is made from the patient's own cells and has shown promise in improving patient outcomes.

The institute will also expand biomarker and biocomputational capacity and improve information systems tools for research.
Researchers found that vitamin D supplements improved vitamin D levels and reduced falls in a five-month trial. The study suggests vitamin D may help maintain muscle integrity and strength, reducing the risk of falls in vulnerable populations.
Research found that prolonged hypoxemia during the first 2-3 months after birth was associated with an increased risk of disability or death at 18 months in extremely preterm infants. The study also revealed that intermittent bradycardia did not significantly add to the risk of adverse outcomes.
A 3-year testosterone supplementation study found no significant association between treatment and atherosclerosis progression. The trial also showed no improvements in sexual function or quality of life, despite increased hematocrit and prostate-specific antigen levels.
A three-year clinical trial found no link between testosterone administration and atherosclerosis progression, sexual function, or quality of life in older men. The study suggests that testosterone should not be used indiscriminately by men, as it may not provide benefits for these outcomes.
A new technique helps doctors optimize cancer treatment doses in phase I/II clinical trials. The Optimal Two-Cycle Dose-Finding Design uses a patient's cycle 1 data to set a dose level for the second cycle, improving patient benefit and controlling toxicity risk.
A preclinical randomized controlled trial was conducted to evaluate a potential stroke therapy that had shown promise in one mouse model but not another. The study found that the treatment's success may depend on the type and severity of the stroke, suggesting improved clinical trial design could have mitigated this issue.
Large-budget clinical trials evaluating drugs or dietary supplements for cardiovascular disease reported fewer positive outcomes after new transparent reporting standards were implemented around 2000. The study found that 57% of trials from 1970-1999 reported positive results, compared to only 8% of trials from 2000-2012.

A new clinical trial found that tamsulosin improves the passage of larger kidney stones, with 83.3% of patients treated with the medication passing their stones compared to 61% on placebo. However, for small kidney stones, time remains the best cure, according to lead author Jeremy Furyk.
A small clinical trial suggests that a genetically-enhanced stem cell therapy can improve blood flow in the lungs and enhance exercise ability in patients with PAH. The therapy was generally well-tolerated, but one patient died after treatment due to severe disease progression.
A new treatment method using magnetic pulses has shown promise in reducing tinnitus symptoms for more than half of study participants. The treatment, known as transcranial magnetic stimulation, targets the auditory cortex in the brain and has been approved only for depression treatment.
