Icosapent ethyl significantly reduces first and subsequent revascularizations, including coronary stenting and cardiac bypass surgery, in statin-treated patients with elevated triglycerides. The study found a 34% reduction in first revascularization events and higher reductions in subsequent events among statin-stabilized patients.
A randomized trial of remdesivir suggests the antiviral drug is not associated with significant clinical benefits for treating COVID-19. Patients treated with remdesivir within 10 days of symptom onset showed faster recovery compared to those given placebo, but results were not statistically significant.
A new 12-week clinical trial found that heat-inactivated Bifidobacterium bifidum MIMBb75 improved IBS symptoms by at least 30% in 34% of patients compared to 19% on placebo. The treatment was also associated with a strong placebo effect, but the dead bacterial cells were still significantly better than placebo.

A randomized clinical trial in Australia compared the effectiveness of SSRIs like fluoxetine with placebos for reducing obsessive-compulsive behaviors in children and adolescents with ASD. The study found lower scores for fluoxetine, but interpretation is limited by high dropout rates and baseline differences between groups.

A study published in Scientific Reports found that psychological placebos can have a positive impact on participants' well-being when attributed to them. The results suggest that the narrative associated with the placebo, as well as the relationship between the researcher and participant, play a crucial role in this effect.
A federally funded study of nearly 400 patients found that compounded topical pain creams and gels offer no statistically significant difference in pain relief compared to placebos. The researchers concluded that people using these creams are being taken advantage of, as the scientific evidence supporting their benefits is lacking.
A new report from a global task force of bone health experts suggests that surgical procedures for spinal fractures may not be effective in reducing pain or improving quality of life. The report recommends against the use of vertebroplasty and balloon kyphoplasty, citing a lack of evidence supporting their benefits.

Researchers developed a new class of hypnotic drugs called dual orexin receptor antagonists (DORAs) that selectively target the brain's sleep/wake pathways. DORA-22 preserves the ability to wake in response to threats, unlike common sleeping pills.
A 12-week exercise intervention reduced visceral abdominal fat in obese adults, but tocilizumab treatment abolished this effect and increased cholesterol levels. Exercise promotes better health and reduces the risk of cardio-metabolic diseases by reducing abdominal fat mass.
A study combining 96 randomized clinical trials found that opioids had small improvements in pain and physical functioning compared to placebo, but also an increased risk of vomiting. Nonopioid alternative pain medications showed similar benefits with lower risks.
A phase 2 trial found that an oral spray containing THC-CBD reduced spasticity in adults with motor neuron disease, improving muscle tone and pain levels. The treatment was well-tolerated and showed promise as a potential option for managing symptoms.
A phase 2 trial of 70 men with cannabis dependence or use disorder found that an experimental drug reduced cannabis use and withdrawal symptoms compared to placebo. The drug, PF-04457845, works by blocking an enzyme that breaks down a natural endocannabinoid chemical in the brain.
A randomized trial found that low-dose tamoxifen (5 mg/day) halved the risk of disease recurrence and new disease in women with DCIS, LCIS, and ADH. Treatment was well-tolerated without significant adverse events.
A Phase 3 clinical trial shows that lanadelumab injections significantly reduce the number of hereditary angioedema attacks, with improvements in quality of life. The treatment also outperforms placebo in reducing attack frequency and severity.
A new study found that denosumab improves spinal bone mineral density and reduces pain in patients with osteoporosis caused by transfusion-dependent thalassemia. The treatment also showed promise in increasing bone density in other areas, such as the wrist and femoral neck.
A phase 3 SOLO-1 trial found that olaparib maintenance therapy significantly improved progression-free survival (PFS) in newly diagnosed patients with advanced ovarian cancer and a BRCA1 or 2 mutation. The median PFS for those who received olaparib was approximately three years longer than the placebo group.
Researchers found that chewing vitamin-supplemented gum increased levels of water-soluble vitamins in saliva and plasma. The study validated the concept of gum as an effective delivery system for at least some vitamins.
The CAMELLIA-TIMI 61 trial found that lorcaserin reduced the risk of diabetes by 19% in patients with pre-diabetes, induced remission in patients with diabetes, and reduced diabetic microvascular complications. Lorcaserin also significantly increased rates of diabetes remission and reduced the risk of severe hypoglycemia.
A new study published in The Lancet found that albiglutide, a GLP-1 receptor agonist, reduces the risk of major adverse cardiovascular events by 22% in patients with type 2 diabetes and established cardiovascular disease. This result is comparable to traditional cardiovascular drugs.
A systematic review of 25 clinical trials found little evidence that invasive surgery reduces chronic pain. The study's findings raise concerns about the widespread use of these procedures without rigorous testing.
A study published in Neurology found that medical marijuana, specifically THC, reduces connections between brain areas processing emotions and sensory signals, providing pain relief for radicular nerve pain. The more pain relief experienced, the greater the reduction of these brain connections.
A clinical trial of over 250 participants with progressive multiple sclerosis found that ibudilast slowed down brain shrinkage compared to a placebo. The study showed a difference of approximately 2.5 milliliters of brain tissue between the two groups, but it is unclear if this translates to improved symptoms or function.
A clinical trial of over 1,000 patients with implantable cardioverter defibrillators found that ranolazine was safe but did not significantly decrease the likelihood of the first occurrence of ventricular arrhythmia or death. However, it did lower the number of recurring episodes of ventricular tachycardia.
The COMMANDER HF trial found that rivaroxaban did not significantly reduce the risk of death, myocardial infarction, or stroke in patients with recent worsening of chronic heart failure and coronary artery disease. Rivaroxaban was associated with a lower rate of nonfatal stroke, but a higher risk of major bleeding compared to placebo.
Tafamidis improves survival and quality of life, reducing hospitalizations in patients with transthyretin amyloid cardiomyopathy. The therapy delays neurologic progression in a similar condition, and has been approved for this condition in the EU.
