A Longitudinal Analysis of Electronic Cigarette Use and Smoking Cessation

dstockzlaja-i-pedjaset2pedja-no-2stock-4-100229272The latest Journal of American Medical Association published a longitudinal analysis evaluating the smoking cessation rates in close to 1600 current smokers using electronic cigarettes. The authors stated that the study did not achieve statistical power, but contributed to the building evidence that e-cigarettes do not increase smoking cessation rates, as often suggested by manufacturers. What is your experience with e-cigarettes – personally or with your patients? Would your current recommendations change after reading this survey?

Steep Increase in ADHD Diagnoses

stressed-out-primary-girl-child-holding-her-head-100155111The Journal of American Medical Association published recent findings from the National Survey of Children’s Health.  When the data was compared between 2003 and 2011, a significant increase in diagnosis of Attention Deficit and Hyperactivity Disorder and medication use among children and teenagers were reported.  Some potential reasons include – physicians are more comfortable with the diagnosis and treatment and there is an increased awareness of this condition.  How often do you talk to parents of these patients about potential alternatives for their ADHD medications?

Excess added sugar intake tied to death

crepe-cake-100194838In a recent study published in JAMA Internal Medicine, researchers from the Centers for Disease Control and Prevention found that participants who consumed more added sugar in their diet were more likely to die of heart disease. Of the 31,000 U.S. adults surveyed between 1988 and 2010, an average of 15 to 17 percent of their daily calorie intake was from added sugars. This is greater than the recommended amount set by the American Heart Association of 100 calories of added sugars per day for women and 150 calories for men and the World Health Organization’s recommendation of 10 percent as the limit. The results showed that participants who consumed between 10 and 25 percent were at a 30 percent increase for cardiovascular disease death and those who consumed 25 percent or more were twice as likely. What tips do you have for patients to minimize added sugar intake?

Mediterranean diet may reduce Peripheral Artery Disease

oil-and-olive-10025527A recent randomized trial published in the Journal of the American Medical Association examined the association between Mediterranean diet and the incidence of symptomatic peripheral artery disease (PAD). Patients were randomly selected to participate in one of the following groups: a Mediterranean diet high in extra-virgin olive oil; a Mediterranean diet high in nuts; or a low-fat diet. The results of the study found that both Mediterranean diet groups had a significantly lower occurrence of PAD compared to the low-fat diet group and no significant difference was found between the two intervention groups. How often do you recommend Mediterranean diet to your patients?

Vitamins for HIV Health?

According to a recent study published in the Journal of American Medical Association (JAMA), preventing HIV progression could be as simple as taking a daily multivitamin. This randomized clinical trial looked at a 897 HIV-positive patients in Sub-Saharan Africa who had not yet started therapy with antiretroviral agents (ARTs)  between 2004-2009. Patients were either given multivitamin containing vitamins B, C & E in combination with Selenium, Selenium without a multivitamin or placebo. Although the results do not show a reduction in viral load, patients taking a multivitamin in combination with Selenium were significantly less likely to have an increased CD-4 count and were less susceptible to immune decline and morbidity. It is thought that the multivitamins are essential in maintaining a functioning immune system and that Selenium may have a role in preventing HIV replication. Although Botswana is a population in Sub-Saharan Africa with the highest rates of HIV infection and limited in resources, this study may have an impact on any population of HIV-positive patients who are naive to ART therapy. What do you think of these findings? Do you think that preventing micronutrient deficiencies will help in any population at risk for HIV?

Are Cranberry Products Good for UTI Prevention?

cranberries1In a recent study published in the Journal of the American Medical Association (JAMA), researchers found that cranberry products were not shown to prevent urinary tract infections (UTIs). The study consolidated the data from 13 previous studies evaluating the efficacy of cranberry products in populations like women with recurrent UTIs, pregnant women, and the elderly. Cranberry products such as the juice, tablets, capsules, and syrup did not do better compared with placebo or no treatment. The authors did note however that low adherence occurred with the cranberry products (especially the juice) and the amount of active ingredient taken was not known. How often do you recommend cranberry products? What are your thoughts about study results? What counseling points would you offer to a patient seeking cranberry products?
