Probiotics — meaning for life — are microorganisms that may help with digestion and offer protection from harmful bacteria just as the existing good bacteria in your body already does.

The most common types of probiotics are strains of tiny organisms called bifidobacterium and lactobacillus.

Some formulas are fortified with probiotics, which are live bacteria. They are good or friendly bacteria that are already present at high levels in the digestive system of breast-fed babies.

Prebiotics are nondigestible carbohydrates that act as food for the probiotics. Prebiotics are found in whole grains, bananas, onions, garlic, honey and artichokes.

When probiotics and prebiotics are combined, they are called synbiotics. Yogurt is an example of a synbiotics, which contains the live bacteria and the fuel they need to survive.

Some research has shown that the probiotics mentioned above may prevent or treat disorders such as infectious diarrhea and atopic dermatitis (eczema) in children. Continue reading

Timeless advice on living good, healthy life

I suspect there is a scientific institute somewhere called “The Institute for Everything that Was Supposed to be Good for You but is Now Bad for You.”

The flux and change in science as well as uncertainty in such fields as nutritional research makes it maddeningly difficult to know what are the best choices for a good and healthy life.

In a recent New York Times opinion piece, “Why Nutrition is So Confusing,” health and science journalist Gary Taubes describes the enormous costs and challenges to creating credible long-term studies on various approaches to nutrition.

There are so many confounding variables, and the long-term effects so hard to track and measure, that we often get conflicting advice. Witness recent confusion on vitamins and omega-3 fatty acids.

Pharmacological and medical research is likewise strewed with the carcasses of old theories and practices.

The very day a couple weeks ago that I wrote about testosterone and obesity in men, a report came out documenting a significant increase in heart attack rate in men on replacement testosterone above a certain age.

Coronary bypass surgery and tube feeding, long thought to be lifesavers, have been found not to prolong life in controlled studies. Continue reading

Stress affects every aspect of health

Our Bodies, Our Lives

A fire races toward your house. This is definitely a stressful situation, but how you handle it may be programmed in your sex genes.

Fight or flight is typically a male response to this type of situation — sticking around to fight the fire or running as fast as you can away from it.

Women have a tend and befriend response to sudden stress. Estrogen blunts the fight or flight response, and we engage in nurturing activities to protect ourselves and our children.

These responses allow us to don a superman or superwoman cape and rise to the occasion. But what happens to our physical and emotional health when the stress is here day in and day out?

Most of us allow stress to sit on our shoulders like unwanted cellulite. You don’t want it, but it tenaciously hangs on.

Stress stimulates the release of various chemicals in our body. The primary stimulating response is the release of catecholamines and corticosteroids, or cortisol, from our adrenal glands. This rush can provide that superwoman response to acute stress. Continue reading

Fungal Drug Forces HIV Suicide

What do nail fungus and HIV have in common? As it turns out, the same drug may cure them both. A topical drug called Ciclopirox, commonly prescribed to treat nail fungus, has been found to kill HIV-infected cells in the lab.

The drugs that are currently used to treat HIV and prevent the progression to AIDS unfortunately do not eliminate the virus from the body. If people stop taking the drugs, the virus will rapidly take control. That means HIV-infected people have to stay on a combination of anti-retroviral drugs for the rest of their lives. Current combination drug therapies are very successful in controlling the virus and have made HIV a survivable disease. But many of the current HIV therapeutics have significant side effects including diarrhea, nausea, vomiting and even damage to the liver and kidneys. They are also expensive: about $10,000 to $12,000 per patient per year in the United States. It has long been a dream to find drugs that could eliminate the virus and cure HIV patients.

HIV is one member of a family of viruses called lentiviruses. When these viruses infect someone, they enter host cells by binding to specific receptors on their surfaces. Once inside the cell, the virus’s genetic information is converted into DNA, the same type of molecule that human genes are made of. The virus has an enzyme that inserts its genetic information into the genomes of the human cells. From that moment, that cell is infected for life. Then the virus replicates and infects other cells.

Are you ready to start a healthier second life?

Dr. Victor Sierpina

If I were to tell you that up to 70 percent of all visits to a doctor are now thought to have a predominantly a single cause, what might you guess? Infections? Genetics? Drug-seeking behavior? Heart disease? Cancer? Diabetes? Pain?

As Maxwell Smart, the wise-cracking detective in the old TV series “Get Smart,” used to say, “would you believe …” lifestyle factors contribute to or cause the vast majority of illness requiring medical attention?

In fact, there is even a new field of medicine named Lifestyle Medicine. I just joined the society and am planning to attend an upcoming conference where I hope to learn more about this area.

I hope to learn how better to help my patients work on lifestyle contributors to their health, wellness and illness.

Any longtime readers of this column know that my topics about health often involve things you can do yourself.

How you eat, exercise, manage stress and so forth are major factors in wellness or illness.

During the weekend, I did a unique presentation called “Second Life on Lifestyle Medicine.” Continue reading

Mental health as important as physical health in children

Keeping Kids Healthy

Hissy fits. Temper tantrums. The blues. Like adults, children also suffer from these conditions from time to time.

But what if it has become an insurmountable problem for your child? When should you seek help for your child? A frank discussion with your pediatrician is a good place to begin understanding the seriousness of your child’s problem.

According to the Surgeon General at the U.S. Department of Health and Human Services, “In the United States, 1 in 10 children and adolescents suffer from mental illness severe enough to cause some level of impairment.

“Yet, in any given year, it is estimated that less than 1 in 5 of these children identified as having a significant mental illness receives needed treatment. The long-term consequences of untreated childhood disorders are costly, in both human and fiscal terms.”

Unfortunately, there is a serious stigma that is placed on people with mental health issues. Because of this stigma, emotional, developmental and behavioral needs cause much suffering in children. Continue reading

The Tomb of an Egyptian Doctor

It’s not every day that archeologists uncover the tomb of an Egyptian pharaoh. But on one special day they discovered not the tomb of a pharaoh but the physician to them. Abusir, the great royal cemetery south of Cairo, is the final resting place of Shepseskaf-Ankh, head physician of Upper and Lower Egypt during the Fifth Dynasty of the Old Kingdom.

This tomb was dated to about 2400 B.C. By this time, the famous pyramids of Giza had already been constructed, so rulers of the Fifth Dynasty built pyramids farther south between 2465 and 2325 B.C. This is the third tomb of a physician discovered so far. They were entombed along with other court officials and high-level priests close to the rulers they served in life, and would continue to do so in death, according to Egyptian beliefs of the afterlife.

Shepseskaf-Ankh was from an elite Egyptian family and also held the title of priest, which was carved on the door of the tomb. It is a relatively large tomb, another indicator of his importance, with an open court and eight burial chambers for him and his family. Continue reading

Women: Care for your heart, know your risks

Dr. Rafic Berbarie

“I’m worried about my risk of having a heart attack.”

Whenever I start my office notes in seeing patients, the first line I fill out is the patient’s chief complaint. The above statement is a common complaint in my general cardiology practice. But often the patients have no symptoms; rather, a friend or loved one just had a heart attack and so they are worried and want a heart “checkup.”

February is heart disease awareness in women month, and as a physician, I want you to know what can be done to help prevent heart attacks.

While awareness is growing, people are often shocked to hear that heart disease is the No. 1 killer of women in the United States. In fact, if you added up how many women died of cancer, the number still would not equal the number of women dying from heart disease.

And while there are established screening guidelines for several cancers, there are no unifying screening guidelines for heart disease in women.

My first recommendation is to have a good primary care doctor who is reviewing your risk factors for heart disease. Continue reading

Testosterone plays role in obesity for men

Men, there is now a simple medical biomarker at-home test for you called CYCYP.

Look straight down and see if you can see your … mmm, anatomy. If not, likely you are suffering from visceral or belly fat, or maybe you have a vision problem.

For many years, we guys have thought of the obesity issue as something that mainly troubled the fairer sex.

It seems it has always been culturally appropriate for the ladies to be concerned about their shapely figures and how to stay attractive for us guys.

We men rarely, if ever, seem to be concerned or even discuss such matters outside of the gym.

However, the surprising news is that obesity or overweight rates for men are at 72 percent and rising, and for women it is 64 percent and stable.

Men also have a higher risk of cancer, diabetes and heart disease with a life expectancy of 76 years compared to 81 for women. Continue reading

Do We Smell the Same Thing?

Medical Discovery News

Have you ever wondered if we all sense the world in the same way? Evidence suggests that the sense of smell is highly individualized, based on genetic differences. This could revolutionize scents and food flavors into custom-designed creations for individuals.

Humans have specialized neuronal cells within the lining the nasal cavities, part of what’s called the olfactory epithelium. The surface of these cells, like much of the nasal cavity, is covered with mucus. Odor molecules dissolve into this layer and are detected when they bind to receptors on the neurons. This sets off a string of biochemical events that produces a signal, which travels along the olfactory nerve to the olfactory bulb of the brain. Then that signal is transferred to different regions of the brain’s cerebrum. Here odors can be distinguished and characterized. These signals are stored in long-term memory, which is linked to emotional memory. That’s why particular smells can evoke memories. This process is quite complex due to the highly evolved sense of smell in humans. Continue reading
