You are enjoying a night out with friends when it starts; first you feel flush, then a sensation of warmth crawls down your body. Soon you begin perspiring and you feel as if everyone around you can tell what is happening – another hot flash. An estimated three out of four women experience hot flashes associated with menopause and nearly all would agree they are a nuisance, but experts say there could be an upside to having hot flashes. New research released today in the online edition of the journal Menopause suggests that women who suffer from hot flashes and night sweats may be at lower risk for cardiovascular disease, stroke and death.

Stent blood clot risk may be higher in the morning

NEW YORK (Reuters Health) - For people who have recently had a stent implanted in a blocked heart artery, the risk of developing a blood clot may be higher early in the morning than other times of day, researchers reported Monday.


Stents are tiny, scaffold-like devices implanted into narrowed heart arteries to help improve blood flow to the heart. In about 1 to 2 percent of patients, a blood clot forms around the stent, which can trigger a heart attack or stroke; the risk is greatest in the few months after the stent is implanted.
The study adds to evidence that the risk of heart problems varies according to the body's circadian rhythms -- the 24-hour cycles that influence sleep, hormone production, body temperature and other essential functions.
It's known that blood pressure, heart rate and the blood cells' "stickiness" tend to increase in the morning -- all of which might contribute to the higher risk of stent blood clots, according to Holmes's team.
But what can patients with newly implanted stents do for now?
Holmes said they can be particularly attuned to potential symptoms of a blood clot early in the morning. Those include chest pain or discomfort and shortness of breath. There are also "atypical" symptoms, like nausea, Holmes noted, and elderly patients are more likely to have those compared with younger people.
"If you wake up feeling 'strange,'" Holmes said, "maybe you're not just feeling strange, and it's something that needs medical attention."
Still, since stent blood clots arise in about 1 to 2 percent of patients, the absolute risk to any one person would be low. And Holmes stressed that, in general, "stents are safe and effective, and very good at preventing symptoms."
"But they are not fail-safe," he said. "And they need careful medical control."

Nicotinic Acid or Niacin Prevents Atherosclerosis

Posted by Prahallad Panda on 6:08 PM Comments

The illustration shows a normal artery with no...Image via Wikipedia
Most common cause of heart attacks and brain strokes is due to atherosclerosis. An early treatment of atherosclerosis is therefore crucial to preventing cardiovascular diseases. Researchers have demonstrated that the LDL(low density lipoproteins) lowering drug nicotinic acid also called niacin or vitamin B3, halts the inflammation of blood vessels. Previously it had been assumed that nicotinic acid mostly alleviates atherosclerosis by reducing the concentration of bad cholesterol and by boosting HDL or good cholesterol in the blood.
Atherosclerosis is a chronically progressive alteration of the arterial wall that can develop over a period of time, in which cholesterol accumulates in the inflamed inner cell layer of the arteries.
New research has shown that it is mainly the chronic inflammation of the vascular wall that promotes atherosclerosis and may lead to acute illnesses such as a cardiac infarction. The classic treatment concept aims to lower harmful lipids such as LDL (low-density lipoprotein) cholesterol or triglycerides, and to increase beneficial lipids, such as HDL (high-density lipoprotein) cholesterol.
In genetically modified mice, it has been demonstrate that nicotinic acid strongly inhibits the progression of atherosclerosis, just as in humans. In mice that lacked the nicotinic acid receptor GPR109A, the agent had no effect on atherosclerosis. In contrast to human cholesterol levels, the cholesterol levels of mice remain constant despite the administration of nicotinic acid. This suggests that nicotinic acid does have an anti-atherosclerotic effect via its receptor, but that this is not due to a change in the lipid concentration.
Further studies showed that the nicotinic acid receptor is present in different immune cells. For example, the receptor was found in macrophages in atherosclerotic blood vessels. When the scientists intentionally blocked the receptor in the cells of the immune system, the effect of the nicotinic acid disappeared. This suggests that the receptor expressed by immune cells transmits the anti-atherosclerotic effect.
These findings suggest that the beneficial impact of nicotinic acid, one of the oldest agents used against atherosclerosis, inhibits inflammation in vascular walls and thereby atherosclerosis.
The unfortunate part of this vitamin is large dose requirement to be effective, mostly 1000 to 2000 mgs/day; that may show different side effects. To minimise the side effects sustained release form is more suitable. Therefore, its dose is gradually increased seeing response and adverse effects in patients.
Nicotinic is available singly and in combination with ezitimibe a triglyceride lowering drug. It is available from vegetables, animal food, diary products and mushroom etc. Its deficiency causes pellagra, mostly seen in maize consuming population because maize is deficient in niacin.

Too Tight Blood Sugar Control in Hospital may be Harmful

Posted by Prahallad Panda on 9:07 PM Comments

A patient having his blood pressure taken by a...Image via WikipediaToo tight blood sugar control in hospitalized diabetic patients may not be required. It has been seen that blood sugar level within 180 to 200 milligrams% does not particularly affect the outcome of the patient.
Medical and surgical patients in the hospital are sometimes prone to hypoglycaemia mainly due to inadequate food intake following surgical procedures.
It should not be interpreted that glucose control isn't important for critically ill patients; It is. And it's important not to let the blood sugar get too high because of the risk of complications, like a higher risk of infection and fluid and electrolyte abnormalities
This is according to American College of Physicians, recommending that doctors not attempt intensive insulin therapy designed to achieve normal blood sugar levels in patients in medical or surgical intensive care units.
These guidelines are for both people with diabetes and without the condition. The college recommends that doctors should maintain blood sugar levels between 140 and 200 milligrams per deciliter (mg/dL) for anyone in medical or surgical intensive care.
These recommendations are similar to the guidelines from the American Diabetes Association (ADA) and the American Association of Clinical Endocrinologists (AACE). However, those guidelines recommend that blood sugar levels should be kept below 180 mg/dL to reduce the risk of infection and other complications.
For reference, in a healthy person with type 2 diabetes, normal blood sugar levels would be between 70 mg/dL and 130 mg/dL before eating. And, even after eating (postprandial), the recommendation from the ADA is to keep blood sugar levels under 180 mg/dL.
Adopting this practice may reduce many hypoglycemic events in the hospital with intense insulin therapy.

Ingrowing Toe Nail

Posted by Prahallad Panda on 7:41 PM Comments

Ingrowing toe nail is mostly due to faulty trimming of the nail. When it is cut in a semi lunar fashion instead of a straight cut; the outer edges tend to bury into the nail bed.

It is advised to trim the nail out side the nail bed in a straight fashion.

However, the home remedy may be read; surgical treatment may be the best.

Health Tip: Don't Ignore Ingrown Toenail


By Diana Kohnle
Thursday, February 10, 2011
(HealthDay News) -- If you have a toenail that's expanded beneath the skin, no doubt it's become sore and painful and needs attention.
If you have poor circulation or diabetes, seek prompt medical treatment. But even if you don't have these medical problems, don't ignore an ingrown toenail.
The ADAM Encyclopedia offers these home-treatment suggestions:
  • Soak the toe in warm water three to four times each day.
  • When you're not soaking, keep your feet dry.
  • Carefully massage the area that's inflamed.
  • Slide a piece of dental floss or cotton, soaked with a little antiseptic or water, underneath the nail.
  • Consider using over-the-counter treatments, but know that they're for pain only -- they won't treat the ingrown toenail itself.
  • Wear open-toed shoes or sandals until the condition improves.
  • If the condition worsens or doesn't improve, see a doctor before infection sets in.

Food for Diabetics

Posted by Prahallad Panda on 6:45 AM Comments

The American Diabetic Association recommends food for diabetics. All the nutrients should be sought from diet as far as practicable.
Amplify’d from www.diabetes.org

Diabetes Superfoods

  • calcium
  • potassium
  • fiber
  • magnesium
  • vitamins A (as carotenoids), C, and E.

There isn’t research that clearly points to supplementation, so always think first about getting your nutrients from foods. Below is our list of superfoods to include in your diet.

Beans


Whether you prefer kidney, pinto, navy or black beans, you can’t find better nutrition than that provided by beans. They are very high in fiber giving you about 1/3 of your daily requirement in just a ½ cup and are also good sources of magnesium, and potassium.

They are considered starchy vegetables but a ½ cup provides as much protein as an ounce of meat without the saturated fat. To save time you can use canned beans, but be sure to drain and rinse them to get rid of as much sodium as possible.

Dark Green Leafy Vegetables


Spinach, collards, kale – these powerhouse foods are so low in calories and carbohydrates, you can’t eat too much.

Citrus Fruit


Grapefruit, oranges, lemons and limes. Pick your favorites and get part of your daily dose of soluble fiber and vitamin C.

Sweet Potatoes


A starchy vegetable packed full of vitamin A and fiber. Try in place of regular potatoes for a lower GI alternative.

Berries


Which are your favorites: blueberries, strawberries or another variety? Regardless, they are all packed with antioxidants, vitamins and fiber. Make a parfait alternating the fruit with light, non-fat yogurt for a new favorite dessert.

Tomatoes


An old standby where everyone can find a favorite. The good news is that no matter how you like your tomatoes, pureed, raw, or in a sauce, you’re eating vital nutrients like vitamin C, iron, vitamin E.

Fish High in Omega-3 Fatty Acids


Salmon is a favorite in this category. Stay away from the breaded and deep fat fried variety... they don’t count in your goal of 6-9 ounces of fish per week.

Whole Grains


It’s the germ and bran of the whole grain you’re after.  It contains all the nutrients a grain product has to offer. When you purchase processed grains like bread made from enriched wheat flour, you don’t get these. A few more of the nutrients these foods offer are magnesium, chromium, omega 3 fatty acids and folate.

Pearled barley and oatmeal are a source of fiber and potassium.

Nuts


An ounce of nuts can go a long way in providing key healthy fats along with hunger management. Other benefits are a dose of magnesium and fiber.

Some nuts and seeds, such as walnuts and flax seeds, also contain omega-3 fatty acids.

Fat-free Milk and Yogurt


Everyone knows dairy can help build strong bones and teeth. In addition to calcium, many fortified dairy products are a good source of vitamin D. More research is emerging on the connection between vitamin D and good health.

Some of the above list can be tough on the budget depending on the season and where you live. Look for lower cost options such as fruit and vegetables in season or frozen or canned fish.

Foods that every budget can live with year round are beans and rolled oats or barley that you cook from scratch.

Of course, you probably don't want to limit yourself to just these items for every meal. The American Diabetes Association's book What Do I Eat Now? provides a step-by-step guide to eating right.

Low Back Pain does not Always Need Costly Imaging

Posted by Prahallad Panda on 7:25 PM Comments

50pman medical imagingImage via Wikipedia
Low back pain (LBP) does not always require costly investigations. It is not only LBP, several diseases do not need all the costly investigations, those are in the armour of the physicians.

The practice of ordering costly imaging should be linked to cost-benefit ratio. After all it is the national resource. Money spend even by an individual unnecessarily is a national loss.

But, doctors are from the same society where corruption is deep rooted; specially so in India. Some of them go unethical sometimes.

That is not good for the society.

The guidelines should be strictly imposed not only in case of LBP, but also in every other disease.

'Selective' Imaging Recommended for Low Back Pain

By John Gever, Senior Editor, MedPage Today
Published: February 01, 2011
Reviewed by Zalman S. Agus, MD; Emeritus Professor
University of Pennsylvania School of Medicine.
Diagnostic imaging is overused in routine treatment of low back pain for various reasons and should be reserved for patients with specific risk factors, according to a new guideline from the American College of Physicians.
Factors that call for imaging studies include the following:
  • Major risk factors for cancer, such as history of cancer combined with new onset of back pain
  • Risk factors for spinal infections
  • Severe neurologic deficits
  • Signs or risk factors associated with cauda equina syndrome, such as new-onset urine retention or fecal incontinence
