Scientists at Ohio State University are studying the potential link between chemotherapy treatment and cognitive problems in patients. Researchers have found that manipulating gut bacteria in mice before chemo may partially reverse side effects such as fatigue and weight loss.
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.

The researchers concluded that people using these creams are being taken advantage of, as the scientific evidence supporting their benefits is lacking.
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 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.

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 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 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.

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.
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.
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.
A weight loss drug, lorcaserin, does not increase the risk of cardiovascular events, according to a study that enrolled over 12,000 adults. The trial found noninferiority of lorcaserin for major adverse cardiovascular events compared to placebo after three years.
A randomized clinical trial found that monthly high-dose vitamin D supplementation without calcium did not reduce cancer risk among adults. The study analyzed data from 2,558 participants who received the supplement and 2,550 participants in a placebo group.
A new study published in The BMJ found that decompression surgery for shoulder impingement syndrome offers no greater relief from pain than placebo surgery. Two years after the procedure, patients in both groups experienced equally little shoulder pain and were equally satisfied with their situation.
Researchers have developed an algorithm that predicts which individuals with depression are most likely to benefit from antidepressant medications. The study found that approximately one-third of participants responded meaningfully to medication, while the remaining two-thirds showed no significant improvement.
Researchers have developed a new ALS therapy that extends survival and reverses signs of neuromuscular damage in mice and rats with SOD1 mutations. The investigational drug, an antisense oligonucleotide, has shown impressive effects in preclinical trials.
Researchers have found that canakinumab significantly reduced the rate of gout flares in patients with stable atherosclerosis by more than half. Serum urate levels were not affected by canakinumab, but it was shown to reduce high sensitivity C-reactive protein (hsCRP) levels.
A phase 2 study found that AMG 714 reduced symptoms and intestinal damage in celiac patients exposed to gluten. The drug was shown to protect against accidental gluten contamination, a frequent occurrence among patients following a gluten-free diet.
Dupilumab alleviates asthma symptoms and improves lung function in moderate to severe asthma patients. The drug significantly reduced asthma exacerbations by half in some patients, with improved rates of emergency room visits and hospitalizations.
A randomized placebo-controlled study found that CPAP treatment significantly lowered resting heart rates during the day and night in patients with OSA and prediabetes. The effects were comparable to those of beta blockers, which block stress hormones and raise heart rates.
Research from the University of Adelaide found that high-dose vitamin B6 supplements improved dream recall in participants. The study revealed no effects on vividness, bizarreness, or sleep patterns, suggesting a potential role for vitamin B6 in lucid dreaming and controlling dreams.
