There have been few studies exploring the link between short bouts of anger and cardiovascular events (in the hours following the outburst), but the evidence is consistently showing a direct relationship.
There were nine independent studies which when combined showed that the risk of heart attack (or acute coronary syndrome) was 4.74-fold higher in the hours after an angry outburst. Certainly, if the angry outbursts are becoming more frequent, the transient effects may accumulate leading to a larger, more ominous event (like a heart attack or stroke).

The increased risk of a cardiac event was increased for individuals who had a greater cardiovascular risk initially.
It is thought that anger can cause increase in circulating catecholamines, increase the heart’s need for oxygen, cause heart blood vessels to spasm, and increase platelet’s ability to make a clot.

There are studies that show that behavioral changes MAY ACTUALLY WORK!

  • One study was a group-based psychosocial intervention designed to reduce stress. This intervention cut mortality among women with heart disease.
  • Another studied showed that cognitive behavioral therapy–focused on stress management—lowered the risk of recurrent cardiovascular events in both men and women who had established heart disease.

Certainly, managing cardiovascular risks (smoking , high blood pressure, elevated blood sugars, obesity) is best to help decrease baseline cardiovascular disease AND we are seeing more information that managing stress may help avoid cardiovascular events, too!

Should you take zinc to help ward off or treat colds?

Maybe.

Zinc may help decrease the duration of a cold, but not the severity of symptoms.

The studies show that the mean difference in reduction of duration as 1 day.
Zinc is included in almost all over-the-counter daily vitamins and mineral supplements. Zinc is absorbed through the small bowel with an efficiency of 20-40%. It is the second most important metal in the body after iron and is present in virtually 100% of proteins.
The important function with regard to colds is that zinc inhibits viral replication making the cold virus not able to multiply. Zinc can be found in many forms: syrup, lozenges, or tablets.

Zinc can be given at the onset of a cold and may decrease the symptoms by one day or it may also be iven dailoy for the prevention of the common cold. If taken daily, there was found to be reduced incidence of colds, less absence from school and less antibiotics were prescribed. Side effects from zinc are nausea and a “bad taste” in the mouth. The dose of zinc should be between 75mg and 150 mg a day. Zinc should not be inhaled as it can cause permanent anosmia (inability to smell). Lozenges may be the best bet.

Five health numbers YOU should know!

New Years’ Resolutions are still on our minds and a common resolution is to be healthier.  At times it feels like managing our health is a numbers game: watching our weight, counting calories, tracking exercise regimens.  Below are five numbers you would benefit from knowing and stabilizing.

Blood pressure.  Goal is less than 120/80.  What is it?  It measures the pressure of blood flowing through your arteries.  The higher the number the increased risk of damaging  blood vessels which reduces the blood flow to the target organ.  Why it’s important?  High blood pressure often does not cause pain.   When untreated, over time, it decreases the blood flow to the brain which can cause dementia, to the heart which can cause heart failure, to the kidneys which can cause kidney failure.

Fasting blood sugar.  Goal is under 100 mg/dL.  What is it?  It measures the amount of sugar in the blood.  Why it’s important? This is a test which screens for diabetes.

BMI.  Goal is under 25.  What is it?  Body mass index is a formula that divides your “mass” (in kilograms) by height (in meters squared).  It determines if your weight is appropriate for your size.  Why it’s important?  Overweight or obese people are at much higher risks for health problems like high blood pressure, diabetes, obstructive sleep apnea, arthritis and heart disease.  A BMI under 18.5 may signal an eating disorder.

Waist size.  Goal is less than 35 inches in women, less than 40 inches in men.  What is it?  The measurement around your belly (above your hipbone and below your ribcage).  Why it’s important?  Large waistlines signs that there may be too much abdominal fat which increases the risk of Type 2 diabetes, high blood pressure and coronary vascular disease.

Total cholesterol.  Goal is under 200 mg/dL.  What is it?  The number is a combination of  low-density lipoproteins (LDL), high-density lipoproteins (HDL), and other fats in your blood.  Why it’s important?  If there’s too much cholesterol in the blood, it keeps circulating and can eventually enter the blood vessel walls causing a buildup of fatty deposits in the arteries.  This “atherosclerosis” can block blood flow (think heart attack and stroke as blood doesn’t get to the heart and brain).

Get to know YOUR numbers.

Let’s discuss ANOTHER old wives’ tale. . . “Brandy soothes teething pain”

Posted on February 25, 2014 by drlesliegreenberg

That may be true, but no amount of alcohol is safe for infants or children.

Teething rings available at stores (many of which can be frozen in the freezer and reused countless times) are best.  For an inexpensive option I’d suggest wetting a washcloth, twist it until it is tightly bound and just slightly wet, and then freeze.  Then let your little teether gum it!

jaydocMy mom recently asked me if I’d suggest that she get a low-dost CT lung scan.  I should say that I am not the physician for my family–although I often do field questions.

Great question!  Low-dose computed tomography (CT) screening for those at high risk for lung cancer has received a grade B (meaning it should be considered helpful) from the U.S. Preventive Services Task Force.   But, not everyone would benefit from a low-dose CT scan. 

Those at “high risk” for lung cancer should be considered for CT screening.

  • aged 55-80,
  • 30-pack year history of smoking (like smoking one pack per day for 30 years)  or more,
  • those who have stopped smoking within the past 15 years,

Lesser known risk factors are

  • some occupational exposures (like radon),
  • family history of lung cancer,
  • incidence of pulmonary fibrosis,
  • or emphysema. 

These guidelines come out of studies published between 2000 and 2013.  The rules of statistics show that this test will benefit those most who are at high-risk.  To screen patients at low risk of lung cancer is more likely to turn up “false positive” results–meaning the test shows there is a problem when there is not.  False positive results often  lead to extra tests (which may involve needles and biopsies) AND lots of worry.

 The mandate from the USPSTF allows the Centers for Medicare and Medicaid Services to mandate that this service be provided without charging a copay or deductible. 

If you are at high risk, ask your physician if this test is right for you. . .

YET ANOTHER old wives’ tale. . . Feed a cold. Starve a fever.

Posted on February 18, 2014 by drlesliegreenberg

Incorrect.

It’s important to eat whether you have a cold or a fever.  Your body continues to need nutrients to boost your immune system (allowing you to fight off the virus that is causing your illness).

Old wives’ tale. . . Caffeine stunts growth.

Posted on February 14, 2014 by drlesliegreenberg

Not true.

Height is not impacted my caffeine intake.  Caffeine does not have any medical benefits, so certainly limiting caffeine for children is prudent.  Caffeine is a drug, just like alcohol, and affects children differently than adults since they don’t process medications as adults do.

Coffee or energy drinks are discouraged.  These frequently contain caffeine AND large amounts of fat and calories.  This can also lead to weight gain and cavities.

Old wives’ tale. . . Spicy food causes ulcers.

Posted on February 11, 2014 by drlesliegreenberg

Wrong.

Spicy food will not CAUSE an ulcer, but if you have an ulcer spicy food will really make you hurt.

Most ulcers are caused by bacteria in the stomach called helicobacter pylori or by high doses or prolonged use of medications like ibuprofen.  If you have an ulcer,  it’s best to avoid smoking, alcohol, caffeine.. and to talk to your doctor.

In what AGE patient is the shingles vaccine the most cost effective?

Posted on February 3, 2014 by drlesliegreenberg

Because the effectiveness of the shingles vaccine appears to decrease over time it is suggested that the vaccine be given once… after age 60.

This is based on the Long-term Persistence Study done by the pharmaceutical company Merck.  The study found a gradual decrease in vaccine effectiveness 6-7 years after vaccination.

Other interested study numbers were that vaccinating with shingles vaccine in patients aged 50-59 would prevent 20,000 shingles cases annually.  But, vaccinating in the patients  60s would prevent 26,000 cases and in the 70s, 21,000 cases.

I agree with their rationale and will suggest shingles vaccine after age 60.

Let’s discuss an old wives’ tale. . . should you gargle salt water for a sore throat?

This works!

Gargling with salt water eases symptoms of cold and flu because of the way that saline works.  Saline draws excess fluid out of inflamed tissues (and loosens mucus!).

A recent study by the American Journal of Preventive Medicine suggested gargling with salt water decreases the chance of an upper respiratory infection by 40%.  This is  cheap, easy to do, AND effective method to combat a common winter cold symptom.
