A phase III clinical trial suggests that adding pertuzumab to standard trastuzumab treatment after surgery may help reduce the risk of invasive breast cancer by 19% in patients with HER2-positive disease. The benefit is most pronounced in women with node-positive and hormone receptor-negative breast cancer.
Adding abiraterone acetate to standard hormonal therapy reduces the chance of death by 38% and doubles the median time until cancer worsens. Cancer growth is delayed by 18 months, but severe side effects like high blood pressure and liver enzyme abnormalities are more common with abiraterone.

The MONALEESA2 study shows a significant improvement in progression-free survival for postmenopausal women with hormone receptor-positive advanced breast cancer when treated with ribociclib plus letrozole. The combination also resulted in higher objective response rates and improved clinical benefits.
A three-armed clinical trial found that spinal manipulation therapy reduced migraine days, but the effect was likely attributed to a placebo response. Migraine treatment with usual drug therapy failed to show sustained benefits.
Research from the Center for BrainHealth found that smokers' beliefs about nicotine content impact their brain's response to smoking. The study used fMRI scans to show that participants who believed a cigarette contained nicotine experienced different neural activity compared to those who believed it didn't.
Two studies found that nasal sprays containing bevacizumab, estriol, or tranexamic acid failed to significantly reduce the frequency and duration of nosebleeds in patients with hereditary hemorrhagic telangiectasia. The treatment also had no measurable effect on quality of life, hemoglobin levels, or red blood cell transfusions.
Researchers found that a simple saline solution twice daily was just as effective as three medications in reducing the frequency and severity of chronic nosebleeds. The study's results suggest that simple hydration may be enough to prevent nosebleeds, making saline nasal spray a potential treatment option.
The phase 3 ODYSSEY-ESCAPE trial found that alirocumab-treated patients had a 75% greater reduction in apheresis compared to placebo, with 63.4% eliminating apheresis altogether. This could mark a new era for HeFH patients struggling with weekly apheresis treatments.
