Overeating may reduce brain function

High caloric intake could raise the risk of memory loss. A recent study suggests that high caloric intake over time may actually raise your odds of developing memory loss, or mild cognitive impairment (MCI), later in life. The study found that consuming between 2,100 and 6,000 calories per day may double the risk of MCI among people age 70 and older.  (Locked) More »

Grieving may trigger heart attack

Grieving people have elevated levels of adrenaline and stress-related hormones. This can lead to increased clamping down of one's arteries, a faster heart rate and elevated blood pressure, all of which can increase the chance of a rupture of atherosclerotic plaques, causing a heart attack.

Dieting? Have some cake

Can eating cake for breakfast help you lose weight? A new study says yes, but the director of nutrition at Brigham and Women's Hospital says "not so fast."  Researchers randomly allocated obese people for four months to either a 600-calorie breakfast rich in both carbohydrates and protein (that included chocolate cake) or to a 600-calorie low-carb diet. After the four months were over, the participants in both groups had lost weight. Over the next four months, however, people who had been on the high-carb, high-protein diet continued to lose weight, while those in the low-carb diet regained weight. More »

Sex after heart attack

The American Heart Association (AHA) has issued a scientific statement noting that sex is safe for the majority of heart disease patients and that patients should discuss the subject with their doctors. "The AHA statement on sexual activity and heart disease is really a big step forward in medicine," says Dr. Deepak Bhatt, an interventional cardiologist and associate professor at Harvard Medical School. "Patients with heart disease often have questions about sexual activity and it is time to start discussing those issues openly." While exercise has been an accepted way to help treat heart patients for years, many heart patients have been concerned about resuming sexual relations because of the strain it may put on their heart or any cardiac devices.

Triglycerides may predict stroke

The strongest predictors of a woman's stroke risk may be triglycerides. Scientists looked at more than 900 post-menopausal women and found that those with the highest levels of triglycerides were 56% more likely to have an ischemic stroke (the type due to blood vessel blockage) as those with the lowest levels.

Eye surgery and post-op pain

Contact lenses are already used after laser eye surgery as bandages. Surgeons place silicone hydrogel contact lenses on the eyes, which can release ophthalmic drugs for a few hours. However, that's inadequate for pain relief. Contact lenses with vitamin E added deliver a long-lasting anesthetic. Vitamin E acts as a barrier and extends the release of the anesthetics, providing relief up to a week after surgery. (Locked) More »

Better way to apply sun screen

Choosing the right sun protection and applying it properly are the most important steps to protect yourself from the sun's harmful rays. The best sun protection for your skin starts with a sunscreen with an SPF of 30 or higher. About one ounce, approximately two tablespoons, is needed for the average adult body. About one quarter to one third of a tablespoon is right for the face. Sunscreen should be applied to dry skin about 15 minutes before going out in the sun and should be reapplied every couple of hours.

Beta blockers

Beta blockers are prescribed for conditions ranging from high blood pressure and glaucoma to anxiety attacks and migraines. They are primarily prescribed to help control hypertension and abnormal heart rhythms, but are also widely prescribed to prevent further heart problems in patients who've had heart attacks or who are suffering from heart failure. Each type of antihypertensive drug works a little differently. Your specific medical needs will help dictate which class of antihypertensives your doctor prescribes.  (Locked) More »
