  1. Heart disease. Rheumatoid arthritis. Diabetes. Alzheimer’s. These and other chronic diseases, affecting the lives of millions of Americans, have something in common — and that is inflammation.
  2. Not only is routine CT to check for recurrence after evacuation surgery for chronic subdural hematoma unnecessary, but patients scanned on an as-needed basis actually experience better outcomes, a new prospective, randomized study Chronic Subdural Hematoma After Neurosurgical Evacuation (TOSCAN) trial
  3. New classification system, with hypertension being diagnosed at a blood pressure of 130 mm Hg systolic, an analysis published May 23 in JAMA Cardiology estimates that the new definition of hypertension means that 45.4% of the US population (105 million adults) are now considered hypertensive, up from 32.0% (74.1 million) according to the definition in the 2014 guidelines. Thats an increase in the number of US adults with a diagnosis of high blood pressure of 31 million, with 11 million of these qualifying for antihypertensive treatment.

Using data from the National Health and Nutrition Examination Survey, antihypertensive clinical trials, and population-based cohort studies, investigators calculate that achieving the 2017 hypertension guideline treatment goals in every individual would reduce major cardiovascular events by an additional 340,000 and total deaths by an additional 156,000 annually compared with the 2014 guideline. But this would also lead to an increase of 62,000 hypotension and 79,000 acute kidney injury or failure events.

Public Health

  1. Views: I personally do not agree with this. In India we can not compare the backward area as the representative of India. Kerala in India may be comparable to the rest of the world. I always say Bharat in India may have poor health parameters, but India in India may have the best of the parameters.
