The randomized, double-blind study demonstrated a sustained benefit of an antibiotic for IBS symptoms even after treatment was stopped.
A new study suggests that rifaximin may improve IBS symptoms by over 50% compared to placebo. However, the researchers caution that antibiotics can have side effects and more research is needed to fully understand its benefits.
Researchers at Karolinska Institutet found that omega-3 fatty acid supplements slowed cognitive decline in a subgroup of patients with very mild Alzheimer's disease, while no effect was seen in those with more advanced disease. The study suggests that omega-3 supplements may be beneficial in halting initial progression of the disease.
