E-cigarette smoking among teens is on the rise, and teens are more likely to transition from smoking e-cigarettes to smoking traditional cigarettes. E-cigarettes are marketed towards young people, emphasizing the need for dialogue between teens and the adults in their lives on the health risks surrounding this trend.

When a cough just won’t go away

There are a number of conditions that can cause a cough to linger for weeks or months. Doctors treating patients with a chronic cough should consider both the more likely and less common possibilities. When a cough persists after those possibilities have been ruled out or treated, new research suggests that irritated nerve ending in the “cough centers” of the airways could be behind a chronic cough.

There’s no sugar-coating it: All calories are not created equal

The view that calories are calories regardless of their source has been shown to be outdated. Foods with a low glycemic index are better because they tend to raise blood sugar more slowly, and they are also more likely to be healthier foods overall. By choosing the low-glycemic foods and thus the minimally processed foods, people can lose more weight, feel fuller longer, and remain healthier.

It may be tempting to carry a water bottle everywhere you go so you can “stay hydrated.” Doctors may advise those taking certain medications or with certain health conditions, to drink more, but most people can get all the water their bodies need from the food they eat and by drinking water when thirsty.

Low levels of HDL (the “good” cholesterol) appear connected to many health risks, not just heart disease

Deepak Bhatt, MD, MPH

Low LDL cholesterol and high HDL cholesterol lower your risk for cardiovascular disease. That is what the studies have always shown us. But a new study suggests that low HDL itself may not be the risk factor for heart disease we thought it was. It could merely be a sign of an unhealthy lifestyle, or other health risk factors, that also contribute to heart disease. Trying to find medications to raise HDL cholesterol may not be as effective as encouraging people to adopt healthier habits.

Experts now recommend that new parents sleep in the same room as their new infant for the first 6-12 months of his/her life. While this might wake the parents up more, it’s much safer for the child. Sudden unexplained infant death (SUID) happens much less frequently when the parents sleep in the same room as their baby. And six months will go by faster than you think.

If it seems like your doctor spends more time during your appointment looking at a computer or paperwork than examining you and listening to you, you’re right, and your doctor is just as frustrated by this. Tasks that distract from time with patients include making sure codes are correct for insurance purposes, completing forms, and updating electronic medical records.

A study of participants in a mindfulness workshop found that the benefits of meditation and yoga are as significant as the relaxation benefit of taking a vacation, and are more persistent. In addition, regularly practicing meditation and yoga can boost immunity, and seems to promote healthier aging.

A recent study found that using an activity tracker, in addition to a careful diet and increased exercise, may not help people lose weight or keep it off. The reasons why are unclear and further studies are needed to determine how, if at all, these devices might aid in weight loss.
