1. Serial measurement of a natriuretic peptide predicted the risk of heart failure and cardiovascular death in older patients who were initially free of heart failure, data from a longitudinal cohort study showed. An increase of more than 25% in levels of N–terminal pro1. Serial measurement of a natriuretic peptide predicted the risk of heart failure and cardiovascular death in older patients who were initially free of heart failure, data from a longitudinal cohort study showed. An increase of more than 25% in levels of N–terminal pro–B type natriuretic peptide (NT–proBNP) doubled the risk of heart failure and cardiovascular death. In contrast, a more than 25% decrease in NT–proBNP was associated with a greater than 40% reduction in the risk of both end points. ‘NT–proBNP levels frequently change over time, and these fluctuations reflect dynamic changes in cardiovascular risk,’ Christopher R. deFilippi, MD, of the University of Maryland in Baltimore, and co–authors concluded in an article in the Feb. 2 issue of the Journal of the American College of Cardiology.
2. So–called silent strokes, visible on cerebral MRI scans, predict kidney failure in patients with type 2 diabetes, Japanese researchers. After an average follow–up of 7.5 years, diabetic patients with evidence of small cerebral infarctions at baseline later suffered death or kidney failure at more than twice the rate seen in patients who had not had silent strokes, reported Takashi Uzu, MD, of Shiga University of Medical Sciences in Shiga, Japan, and colleagues.
3. A little excess weight after age 70 could do the body some good, according to results of a study involving 9,000 older patients. Overweight participants in the cohort study had the lowest 10–year mortality. Normal–weight and obese participants ages 70 to 75 had a similar and slightly higher risk of death, Leon Flicker, PhD, of the Western Australian Center for Health and Aging in Perth, and colleagues found. The findings add to evidence suggesting that being overweight in older age is not such a bad thing and might even be beneficial. The results of the study lend further credence to claims that the body mass index [BMI] thresholds for overweight and obese are overly restrictive for older people. The study is published in the Journal of the American Geriatrics Society.
4. When New York City public schools made the switch from whole milk to skim or low–fat milk, students cut their annual fat and total calorie consumption. Milk–drinking students consumed 5,960 fewer calories and 619 fewer grams of fat per year after they made the switch. This was reported by Philip M. Alberti, PhD, of the New York Department of Health and Mental Hygiene, and colleagues in the Jan. 29 issue of CDC’s Morbidity & Mortality Weekly Report. At 3,500 calories per pound, the reduction would be the equivalent of 1.7 pounds of body weight over the course of a year.
5. Using computed tomography (CT) to diagnose appendicitis may reduce the likelihood of removing healthy organs in women under 45, but not among other groups, a retrospective study showed. Over a 10–year period, the use of preoperative CT increased from 18.5% of patients who ultimately had their appendices removed to 94.2%, according to Courtney Coursey, MD, of Duke University Medical Centeri, and colleagues. During the same time period, the rate of negative appendectomy (removal of a healthy organ) declined, although the trend was significant only among women 45 and younger the researchers reported in the February issue of Radiology.
6. People with non–alcoholic fatty liver disease (NAFLD), a condition that often accompanies obesity and type 2 diabetes, have higher mortality rates than the general population, a new Swedish study found. Patients with NAFLD were 69% percent more likely to die than the general Swedish population (standardized mortality ratio 1.69, 95% CI 1.24 to 2.25), according to a report in the February issue of Hepatology.

Stay away from stress during examination days
Exam stress can lead to depression and suicide. During exam days, prescriptions for anti depressant drugs, so called ‘happy drugs’, increase amongst teenagers, said Dr. KK Aggarwal, President, Heart Care Foundation of India and Editor eMedinewS.
The fear of failure and fear of letting down are the two most common factors leading to suicide and depression.
Also, children indulge in drugs to keep awake during the exam and end up in addictions. Some use commonly available cough syrups, anti fit drugs, while others indulge in smoking, tobacco, alcohol, tea, coffee, and drugs like LSD, etc. Few take memory enhancing pills. Some children go to the extent of even eating lizard tail to beat exam stress. Some eat junk food so that they do not waste time in eating food.
Anticipatory anxiety peaks before exams resulting in adverse affects on the body and mind and therefore, a sub optimal performance. Stress not only causes palpitations and tense muscles but also reduces the ability to make decisions, act or express oneself including organization of thoughts.
Stress during exams can makes it difficult to read and understand questions and even to recall terms and concepts.
A recent study has shown that 45 minutes of afternoon nap improves the declarative memory. Declarative memory is the memory of events learnt and understood earlier during the year. Not taking afternoon nap or the night sleep may end up in transient loss of declarative memory. Yoga exercises like pranayam maybe done to relax oneself. Deep breathing exercises should be followed before the exam. One should learn quick relaxation & breathing techniques.
