April 25, 2007 Patients with HIV who are treated with protease inhibitors have an increased risk of heart attack, according to a study published in the New England Journal of Medicine. Combination antiretroviral therapy has had a dramatic effect in reducing illness and death associated with the HIV virus, however an earlier study showed that the risk of heart attacks increased by 17% with every year a patient spent on antiretroviral. It isn’t known, though, whether all antiretroviral drugs carry this risk. The assessment of the role of any specific drug is difficult because patients with HIV usually receive a combination of drugs, and often switch regimens because of the availability of newer substances, adverse events, or drug regimen failure. Previous studies have shown a relationship between the use of protease inhibitors, a class of antiretroviral drug, and cardiovascular disease, but there is little information on the risks associated with another class of antiretroviral therapy called nonnucleoside reverse-transcriptase inhibitors. In this study, more than 23,000 patients infected with the HIV virus were assessed to determine the incidence of heart attack and the association between heart attack and exposure to protease inhibitors or nonnucleoside reverse-transcriptase inhibitors. Confirming the earlier results, the researchers found the risk of having a heart attack increased by 16% per year of exposure to protease inhibitors alone, which is equal to twice the risk over five years. Not such effect was observed with nonnucleoside reverse-transcriptase inhibitors. It is thought that protease inhibitors raise the level of blood lipid, thereby increasing the risk of cardiovascular disease and heart attack. Patients treated with protease inhibitors should have their cholesterol and blood pressure levels monitored, and take steps to reduce their lifestyle-related risk factors. This includes maintaining a healthy weight, eating a low-fat diet rich in fruits in vegetables, and getting regular exercise. Reporting for Insidermedicine, I'm Dr. Susan Sharma.

High resting rate linked to risk of death, even in fit and healthy people

(April 15, 2013 - Insidermedicine) From Denmark – A high resting heart rate is associated with a raised risk of death—even in people who are fit and healthy, according to a report published in Heart. Researchers studied 3,000 men taking part in the Copenhagen Male Study. Participants had their cardiovascular health assessed in 1971, 1985 and 2001. Nearly 40% of the men died by the end of the study. Researchers found that a resting heart rate of 51 to 80 beats per minute raised risk of death by 40-50%, and a resting heart rate of 81 to 90 raised risk twofold. Results showed that the higher the resting heart rate, the higher the risk of death—regardless of fitness level.

No proof that drugs, herbal remedies or vitamin supplements prevent mental decline

(April 15, 2013 - Insidermedicine) From Toronto - A new report published in the CMAJ finds no proof that drugs, herbal products or vitamin supplements prevent mental decline. Researchers conducted a meta-analysis of over 30 trials covering nearly 25,000 individuals. They found no evidence that pharmacologic therapies such as cholinesterase inhibitors prevented decline in thinking, judgment and memory skills. As well, researchers found no evidence that herbal supplements such as ginko, or vitamin supplements such as omega-3 fatty acids, actually improved cognitive skills. Interestingly, some of the studies found that estrogen increased risk of cognitive decline and dementia.

Americans frequently partake in one healthy activity at the expense of another

(April 12, 2013 - Insidermedicine) From Ohio – A new report presented at the annual meeting of the Population Association of America finds that American adults often spend time on one healthy activity at the expense of another. Researchers reviewed data on over 110,000 American adults who had reported all of their activities for the previous day. 16% of male participants and 12% of women reported exercising. The average time spent exercising for the entire group was 19 minutes for men and 9 minutes for women. Men spent an average of 17 minutes preparing food, while women spent 14 minutes. Researchers found that a 10-minute increase in time spent preparing food lowered the likelihood of exercising for 10 more minutes—suggesting that time spend with one healthy behavior is done at expense of the other.

L-carnitine great improves outcomes after heart attack

(April 12, 2013 - Insidermedicine) From New York - L-carnitine greatly improves outcomes following heart attack, according to a report published in the Mayo Clinic Proceedings. Researchers conducted a meta-analysis of 13 trials and nearly 4,000 heart attack patients. All of the trials compared outcomes of L-carnitine nto placebo or control for care of heart attack. Results showed that L-carnitine was associated with a 27% reduction in all-cause mortality, a 65% reduction in ventricular arrhythmias, a 40% reduction in angina development, and a reduction in the size of infarct.

Rates of squint surgery drop dramatically in England

(April 11, 2013 - Insidermedicine) From Oxford - Rates of strabismus surgery have fallen significantly in England over the past 50 years, according to a report published in the British Journal of Ophthalmology. Researchers reviewed data on squint surgery on children under the age of 15 in England from 1968 to 2010. During the study period, there were nearly 520,000 children admitted for corrective surgery. Annual admission rates droped from 188 per 100,000 people under 15 years old in 1968 to 64 per 100,000 in 2010. However, researchers also found a 5-fold difference between the areas in England with the highest rates and those with the lowest rates--a discrepancy that researchers cannot explain.

Androgen may be a major factor fueling breast cancer

(April 11, 2013 - Insidermedicine) From Colorado – A new report presented at the AACR annual meeting identifies androgen as a major factor driving breast cancer. Researchers reviewed breast cancer registries and found that cancers with a higher ratio of androgen receptor to estrogen receptor relapsed faster after receiving anti-estrogen therapy. Researchers then tested the anti-androgen drug enzalutamide in the laboratory on cell lines and found that the therapy had a positive result comparable to tamoxifen.

Possible link between HPV infection and lung cancer

(April 11, 2013 - Insidermedicine) From Philadelphia – Some lung cancers may be linked to HPV, according to a report presented at the AACR annual meeting. Researchers studied over 30 tissue samples from a group of lung cancer patients who had never smoked. They found that 4 (or 6%) of the samples had signs of infection from two HPV strains known to cause cancer, HPV 14 and 16. When researchers examined 2 of the samples that were infected by HPV 16, they found that the virus was engrained in the tumor's DNA. These findings suggest that the HPV infection caused the tumor

Causes of decreased visual acuity in preschool aged children

(April 10, 2013 - Insidermedicine) From California – A new report published in Ophthalmology examines the causes of decreased visual acuity in preschool children. Researchers studied visual acuity in a mutli-ethnic group of children aged 30-72 months. Researchers defined decreased visual acuity as worse than 20/50 in those under 47 months, and worse than 20/40 in those over 48 months. Results showed 70% of all cases of decreased VA in both Asian and non-hispanic white children, and 90% of cases with decreased VA that had an identifiable cause, were due to a refractive error.

(April 10, 2013 - Insidermedicine) From Pennsylvania – A substance found in unroasted coffee beans helps regulate blood sugar levels, according to a report presented at the annual meeting of the American Chemical Society. Researchers studied 56 men and women with normal blood sugar levels, measuring participant’s response to sugar with a glucose tolerance test. Participants then received increasing doses of chlorogenic acids—an extract from green coffee beans that is also available as a supplement. After administering follow-up glucose tolerance tests, researchers found that every dose of the extract resulted in a significant reduction in participant’s blood sugar levels
