Had a “senior moment” lately? You know, those sudden, momentary lapses when you just can’t seem to remember the most common things. For most of us, we will experience what physicians term normal cognitive aging. Now, Columbia University researchers say that elevated blood glucose levels that occur naturally when we age may contribute to age-related cognitive decline. “This is news even for people without diabetes since blood glucose levels tend to rise as we grow older. Whether through physical exercise, diet or drugs, our research suggests that improving glucose metabolism could help some of us avert the cognitive slide that occurs in many of us as we age,” reported the lead investigator. Although regularly checking your blood sugar level isn’t recommended for non-diabetics, daily exercise is recommended for everyone (especially diabetics) because it contributes to normalization of blood glucose.

Michigan State University researchers are suggesting that improper dieting may result in a weakened immune system that can increase your chances of getting hit hard by the flu. When looking at mice receiving adequate nutrition versus a lower calorie diet, those on the diet were not able to produce the amount of immune cells needed to fight an infection, despite consuming adequate quantities of vitamins and minerals. Although this was a mouse study, we probably didn’t need it to tell us why the results make sense on a human scale. Our bodies need energy in order to fight infections, and although vitamins and minerals are necessary, they do not provide the majority of energy we need to fuel our bodies - that role is reserved for carbohydrates, fats and proteins. This is why I always tell my patients to eat well and sleep well during flu season. Therefore, don’t believe the old saying telling you to “starve a fever.” It simply is not true.

Smoking is a major risk factor for heart disease, including heart attacks. It is, therefore, no surprise that the CDC reported this week that hospitalizations for heart attacks in Pueblo, Colorado have sustained a 3-year decrease after the city implemented a law making public and work places smoke-free. Multiple studies have shown similar rapid and dramatic decreases within one year after the implementation of smoke-free laws. However, this was the first study to show that the benefits continue years after the initial drop.

Is it new year resolutions time again? Researchers from Norway report that patients who were scheduled for colonoscopies around the December-January holiday season were one and a half times more likely to keep their appointments. Similarly, patients who were given medical appointments in the weeks immediately subsequent to their birthdays had higher attendance rates. The researchers believe that reminders of aging triggered by annual milestones may be the underlying mechanism for the increased compliance. This certainly sounds logical. Screening programs - and physicians at large - should keep this in mind as a cost-effective way of improving patient compliance.

The American Cancer Society kicked off their 33rd annual Great American Smoke Out yesterday in an effort to help smokers quit. The goal of the event is to get smokers to quit for one day, in hopes that the day will inspire them to remain smoke-free for good. Smoking is the major risk factor for lung cancer, the top killing cancer globally in both men and women. Studies have found by calling 1-800-Quit-Now, a free service in the US, a person’s chances of successfully quitting tobacco more than doubles.

The journal Human Reproduction reports on a nationwide US study which has found that babies conceived through Assisted Reproductive Technology (ART), such as in vitro fertilization and intracytoplasmic sperm injection, have higher rates of birth defects. Compared to infants conceived without ART, the CDC study found that in pregnancies which resulted in single births, ART was linked to twice the risk of certain heart defects and cleft lips and more than four times the risk of some types of gastrointestinal defects. Although the relative risk of birth defects are still low, it is certainly a consideration for couples who choose to conceive with ART.

Regular aerobic exercise has been extensively studied and is known to have long-term cardiac benefits. However, did you know that listening to your favorite tune can dilate your blood vessels the same way exercise or drugs used to treat high blood pressure and cholesterol do? Researchers have shown that when people listen to music that makes them feel good (you pick the song) the effect of blood vessel dilation can last for almost an hour afterwords. Blood vessels that are able to react by dilating are termed as more “elastic.” More elastic vessels decrease the risk of atherosclerosis and blood clot formation that can lead to stroke and heart attacks.

The CDC reported earlier this year that approximately 32% of US children were overweight, 16% were obese, and 11% were extremely obese. With concerns about weight on the minds of most Americans these days, many food companies have voluntarily began campaigns to combat the obesity epidemic by categorizing a certain amount of their products as “healthy alternatives.” But do these wellness initiatives truly have the consumer in mind? In a recent JAMA article pediatrician David Ludwig and Marion Nestle, professor of nutrition at New York University, argues that makers of popular junk foods ultimately have obligations to their stockholders to encourage children to consume more, not less. In an interview with U.S. News they outlined the top 10 things that the food industry doesn’t want you to know, including the following:

- Junk food makers donate large sums of money to professional nutrition associations.

- Less-processed foods are generally more satiating than their highly processed counterparts.

- The food industry funds front groups that fight antiobesity public health initiatives.

In a report titled “Progress for Children: A Report Card on Maternal Maternity” the United Nations Children’s Fund (UNICEF) states that the number of mothers who died during pregnancy or childbirth remain largely unchanged. Over 99% of the estmated 536,000 worldwide maternal deaths in 2005 occurred in developing countries - half of them in sub-Saharan Africa. “One of the critical bottlenecks has always been access to highly skilled health workers required to deliver emergency obstetrical care, particularly caesarian sections,” Peter Salama UNICEF’s chief of health, told a news briefing. The leading causes of maternal death include hemorrhaging, infections, blood pressure problems, complications of abortions, obstructed labor, and HIV/AIDS. Read more and share your opinion.

At this week’s American College of Gastroenterology annual scientific meeting, researchers presented data which supports that women require less exposure to tobacco in order to increase their risk of colorectal cancer. Heavy smokers were almost twice as likely to develop significant colorectal cancer than women who were not exposed to tobacco smoke. The researchers also found that smoking can raise the risk of pancreatic pre-cancerous growths, especially in people who have a strong family history of the pancreatic cancer. Read more.
