2/21/15 Health News: Safety and efficacy of statins exaggerated-- Rivers source antibiotic resistance--Higher risk of second stroke identified-- higher risk of second stroke identified

Safety, life-saving efficacy of statins have been exaggerated, says scientist  Statins, the cholesterol-lowering drugs prescribed to prevent heart attacks, are not as effective nor as safe as we have been led to believe, researchers say. Statins produce a dramatic reduction in cholesterol levels, but have failed to substantially improve cardiovascular outcomes, they add, stating that 'statistical deception' has been used to inflate claims Continue Reading
Thames study: Rivers can be a major source antibiotic resistance  Rivers and streams could be a major source of antibiotic resistance in the environment. A new study found that greater numbers of resistant bacteria exist close to some waste water treatment works, and that these plants are likely to be responsible for at least half of the increase observed.

Patients at higher risk of second stroke identified  Risk of recurrent stroke is higher in patients who have low blood flow to the back of the brain, a six-year, multi-center trial has found, and the condition can be visualized using specialized software that analyzes blood flow using standard MRI.

Immune cells commit suicide to prevent allergy  Scientists have demonstrated that the production of type E immunoglobulins (IgE) by B lymphocytes induces a loss in their mobility and the initiation of cell death mechanisms. These antibodies, present in small quantities, are the most powerful "weapons" in the immune system and can trigger extremely violent immune reactions or immediate allergies (asthma, urticaria, allergic shock) as soon as their levels rise, even slightly.

Anti-inflammatory mechanism of dieting and fasting revealed  Researchers have found that a compound produced by the body when dieting or fasting can block a part of the immune system involved in several inflammatory disorders such as type 2 diabetes, atherosclerosis, and Alzheimer's disease Continue Reading
