The study found that the conversion of testosterone to DHT is not necessary for its effects on muscle mass, strength, and other body functions. The findings suggest that 5α-reductase inhibitors may be safe for men with normal or high testosterone levels, but measurement of testosterone levels may be useful to identify those less likely...
A phase III clinical trial shows that ruxolitinib relieves severe symptoms and extends survival in patients with myelofibrosis. The drug also shrinks swollen spleens, a hallmark of the disease, and improves quality of life for many patients.
TAK-875, a novel oral medication, enhances insulin secretion in a glucose-dependent manner, improving blood sugar control and lowering the risk of hypoglycemia. The study showed significant reductions in HbA1c levels across all TAK-875 doses, with higher efficacy rates compared to glimepiride.
Patients with chronic kidney disease did not show significant improvement on measures of cardiac structure, function, or left ventricular mass after receiving vitamin D compound paricalcitol for up to 48 weeks. However, the study found fewer hospitalizations for cardiovascular events in the treatment group compared to placebo.
According to investigators at Washington University School of Medicine, antibiotics do not reduce symptoms in sinus infection patients, with most people getting better on their own. The study suggests treating symptoms and watchful waiting may be more effective than antibiotic treatment.
A new study by the American Heart Association found that combining clopidogrel with aspirin for stroke prevention in patients with subcortical strokes may increase the risk of bleeding and death. The trial involved over 3,000 patients and showed that there was no difference in stroke recurrence between treatment arms.
A new study found that when combining a placebo with a distracting memory task, participants experienced increased pain reduction without cognitive interference. This challenges the theory that the placebo effect relies on high-level cognitive functions like working memory and attention.
A new drug, AX200, manufactured form of G-CSF, failed to show efficacy in improving disability among stroke patients. Despite initial promising results in animal studies and a limited clinical trial, the study found no significant improvement in disability scores.

A study published in JAMA found that adding risperidone to ongoing antidepressant therapy did not reduce PTSD symptoms in veterans with chronic, treatment-resistant symptoms. The researchers concluded that the data do not support widespread prescription of risperidone for this patient population.
A Cochrane Systematic Review found that short-term amphetamine use can improve Attention Deficit Hyperactivity Disorder (ADHD) symptoms in adults. However, the high risk of adverse events and limited duration of treatment restrict its effectiveness.
A randomized double-blind placebo-controlled trial found that adrenaline increased the likelihood of restoring circulation following cardiac arrest, but no difference was seen in survival to hospital discharge. The study provides the best evidence to date supporting the use of adrenaline in treating cardiac arrest.
A study examining placebo treatments in asthma patients found that they were equally effective as albuterol inhalers in relieving patient-reported symptoms. However, there was no objective impact on lung function, highlighting the subjective nature of the placebo effect.
A new study found that varenicline, a commonly used smoking cessation drug, is associated with a 72% increased risk of serious adverse cardiovascular events. The research suggests that clinicians should carefully weigh the risks and benefits of using this medication for tobacco dependence treatment.
New data from the Phase III study confirm linagliptin's efficacy in lowering blood glucose and reducing hypoglycemia risk when added to metformin. The medication also demonstrates cardiovascular safety, with a 54% relative risk reduction for cardiovascular events.
A study by Dr Jay S Skyler and colleagues found that abatacept slows the loss of insulin-producing beta-cells in type 1 diabetes patients, but only for the first six months. The treatment helps modulate T-cell activation, resulting in higher C-peptide levels.
A lower dose of zoledronic acid has been found to increase bone density and decrease bone resorption, potentially reducing the risk of osteoporotic fractures. The study suggests that a one-fifth or one-half of the recommended dose may be sufficient for this effect.
A Phase III study presented at EULAR 2011 found that tofacitinib achieved significant improvements in symptoms and activity scores for patients with active rheumatoid arthritis (RA), including improved ACR20 responses in 58.3% of patients, and a higher proportion of patients achieving ACR50 and ACR70 responses compared to placebo
A large randomized trial in rural Bangladesh found that supplementation with vitamin A or beta carotene did not reduce all-cause maternal, fetal, or infant mortality. The study suggested that preventing vitamin A deficiency could improve maternal survival, but the benefits of supplementation were unclear.
A traditional Chinese herbal paste called Xiao Chuan has been shown to reduce the frequency of winter exacerbations of chronic obstructive pulmonary disease (COPD). The study, conducted in Beijing, found that patients treated with XCP experienced statistically significant reductions in steroid use and episodes of shortness of breath.
Pirfenidone reduces lung function decline in idiopathic pulmonary fibrosis patients, showing a clinically meaningful benefit and favourable safety profile. The treatment has been approved for mild to moderate idiopathic pulmonary fibrosis in Europe and shows promise for the estimated 100,000 people affected across the continent.
A recent survey led by McGill Psychiatry Professor Amir Raz found that one in five respondents, mostly psychiatrists, have administered or prescribed placebos. The majority of responding psychiatrists (more than 60%) believe that placebos can have therapeutic effects.
A study found that erythropoietin use in heart attack patients after PCI did not reduce infarct size and was associated with higher rates of adverse cardiovascular events. The REVEAL trial evaluated the safety and effect on infarct size of a single intravenous dose of recombinant human erythropoietin.
A new study found that extended-release naltrexone is an effective treatment for opioid dependence, with patients experiencing high rates of abstinence and reduced craving. However, critics argue that the FDA's approval of this drug was premature and failed to adequately investigate risks, such as post-treatment overdose.
A randomized controlled trial found that vitamin E and metformin did not demonstrate significant efficacy in reducing liver disease severity or improving insulin resistance in children. The study suggests that lifestyle modification is crucial, while further research into non-invasive markers is warranted.

The study found significant reductions in blood pressure, hemoglobin A1C, and inflammatory markers, as well as improvements in cholesterol and triglycerides.
A University of Iowa study finds that patients treated with antidepressants after a stroke have significantly greater improvement in physical recovery than those on placebo. The study demonstrates that this effect continues to improve for at least nine months after the medication is stopped.
A longer-term follow-up of postmenopausal women who used estrogen therapy for 6 years found that the increased risk of stroke during treatment had dissipated, while the decreased risk of breast cancer persisted. The risk of hip fracture was not maintained during the postintervention phase.
A study published in PLoS ONE found that simulated acupuncture, also known as placebo, was just as effective as real acupuncture in reducing nausea in cancer patients undergoing radiotherapy. The researchers suggested that the benefits may be due to patient expectations and extra care received during treatment.
A randomized trial found hydrocortisone therapy reduced hospital-acquired pneumonia rates by 35.6% compared to placebo, resulting in shorter mechanical ventilation-free days and ICU stays. Corticosteroid insufficiency was also associated with higher pneumonia rates.
A new study sponsored by the National Heart, Lung, and Blood Institute found that sirolimus therapy can improve lung function and quality of life in individuals with lymphangioleiomyomatosis (LAM). The treatment was shown to slow disease progression and improve clinical outcomes in patients with this rare and progressive lung disease.
A recent trial found the combination of rituximab, a TNF inhibitor, and methotrexate showed a consistent safety profile for rheumatoid arthritis patients. While no new safety concerns were identified, clear efficacy benefits were not observed in this study sample.
