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.

(December 12, 2012 - Insidermedicine) From New Zealand - Taxing unhealthy food and drinks can lead to positive dietary changes, according to a report published in PLOS Medicine. Results of a meta-analysis covering over 30 studies found that a 10% increase in the price of soft drinks could decrease pop consumption by as much as 24%. As well, every 1% increase in price on foods with saturated fats could result in a small decrease in the amount of saturated fats consumed. A 10% decrease in the price of fruits and vegetables, on the other hand, could increased consumption from 2-8%.

(December 11, 2012 - Insidermedicine) From New Mexico - Concussions have a lasting impact on children's brains, even after the symptoms subside, according to a report published in the Journal of Neurscience. Researchers conducted imaging tests on 15 children who had suffered a concussion in the previous 3 weeks and 15 children who had not suffered a concussion. Follow-up lasted 4 months post-injury. Initial imaging revealed that children who suffered a mild brain injury demonstrated small cognitive deficits as well as changes to the white matter of their brain. Follow-up testing revealed found the changes to the white matter had remained, even though the symptoms had disappeared.

Visual impairment rising in the US, possibly due to increase in diabetes

(December 11, 2012 - Insidermedicine) From Baltimore - A new report published in the Journal of the American Medical Association finds that visual impairment is on the rise in the US. Researchers reviewed data from 1999-2008 taken from the NHANES study. Their analysis included over 20,000 individuals over the age of 20, all of whom had received questionnaires, lab tests, and physical examinations. Non-refractive visual impairment--not due to need for glasses--was defined as visual acuity less than 20/40. Results showed that visual impairment increased by 21% from 1999 to 2008. Impairment among non-Hispanic whites increased by 40% over the same time period. Factors associated with this impairment included diabetes, poverty, lower education, and older age. However, over the study period, only prevalence of diabetes increased--especially among the non-Hispanic white population. Researchers believe that rising prevalence of visual impairment in the US can be partly explained by a similar increase in diabetes.

Even moderate smoking raises a woman's risk of sudden cardiac death

(December 11, 2012 - Insidermedicine) From Alberta - Even moderate smoking can raise a woman's risk of sudden death, according to a report published in Circulation: Arrhythmia & Electrophysiology. Researchers studied the incidence of sudden cardiac death among over 100,000 women taking part in a study that began in 1976. Participants were between 3-55 years old at the outset of the study. Results showed that: -Those who smoked one to 14 cigarettes a day had a nearly twofold increased risk of sudden cardiac death when compared to those who did not smoke. -Every additional 5 years spent smoking raised risk by 8% -Women who quit had an immediate reduction in their risk We spoke with study author Dr.Roopinder Sandhu, MD, MPH, who had this to say:" "Our data suggests there's a significant dose-response relationship between the quantity of cigarettes smoked daily and the risk of sudden cardiac death. So the more cigarettes smoked, the higher the risk of sudden cardiac death. But we found that even small to moderate quantities of daily smoking, defined as 1-14 cigarettes per day, were associated with almost a twofold increase in sudden cardiac death risk, compared to women who never smoked. We found a similar significant dose-response relationship with duration and risk of sudden cardiac death. And when you broke down duration into every 5 year increments, we found an 8% increased risk of sudden cardiac death. But importantly, women who quit smoking had a lower sudden cardiac death risk which continued to decrease over time, and was equivalent to that of a never-smoker in 20 years. In a secondary analysis, we also looked at whether the association between smoking and smoking cessation differs once heart disease becomes clinically manifest. And what we found is that women without a known history of heart disease had a more immediate reduction in their sudden cardiac death risk after quitting as compared to women with previously diagnosed heart disease (their risk reduction was more eventual). And what this tells us is that cigarette smoking is an important modifiable risk factor for sudden cardiac death among all women--with and without heart disease. So, cessation should not wait until you develop heart disease."

(December 10, 2012 - Insidermedicine) From the Netherlands - Loneliness in later life may raise risk of dementia, according to a report published in the Journal of Neurology Neurosurgery and Psychiatry. Researchers examined over 2,000 elderly people who were free of dementia at the outset of the study. Participants were followed for 3 years. They found those who felt lonely were over 2.5x more likely to develop dementia during the study period when compared to those who did not feel lonely. After taking into account other influential factors, those who reported feeling lonely were at 64% increased risk of the neurological condition.

(December 10, 2012 - Insidermedicine) From Michigan - Visual field testing for glaucoma patients has declined among all ethnic groups in the US, and especially among Hispanics, according to a report published in the Archives of Ophthalmology. Researchers reviewed data on nearly 150,000 glaucoma patients to determine how often visual field testing is performed. They found that from 2001-2009, the odds of undergoing visual field testing for glaucoma decreased for all racial groups. Visual field testing decreased by 63% in Hispanic men and 57% for Hispanic women

(December 9, 2012 - Insidermedicine) From Oxford - According to research published in Human Reproduction, children who are born after infertility treatment are at raised risk of asthma. Researchers studied a cohort of nearly 20,000 children, following 13,000 of the children until the age of 5. They found that children who were born to sub-fertile parent--those that either had to wait a a year before conceiving or who needed infertility treatment--were 39% more likely to experience asthma at the age of 5, as well as 27% more likely to wheeze and 2x more likely to be taking asthma medication. Specifically, researchers found that children born after assisted reproduction technology, primarily in vitro fertilization and intracytoplasmic sperm injection, were at 2.5x increased risk of asthma at age 5, as well as a 2x increased risk of wheezing and 4x increased risk of taking asthma medicate on. From Birmingham - A person's risk of skin cancer includes more than just sun exposure, according to a report published in Genetics. Researchers examined genetic data on over 5,000 individuals taking part in a long-term study. Several predictive models were used to assess a person's risk of skin cancer, and the accuracy of each model was compared. Results showed that the predictive model that was the most accurate was one that accounted for standard risk factors, such as sex, as well as predicitve risk factors such as family history, ethnicity, UV exposure and genetic markers

Childless women at raised risk of early death; Tamoxifen therapy can save lives if extended for 5 additional years
(December 8, Insidermedicine - Week in review) From Denmark - ...
(December 8, Insidermedicine - Week in review) From Denmark - Childless women are at raised risk of early death, according to a report published in the Journal of Epidemiology and Community Health. Researchers reviewed data from several population registries over a 14 year period. They found that childless women were 4x more likely to die early from circulatory disease, cancer, and accidents than women who had given birth to their own child. Women who adopted a child had 50% lower death rates. Mental illnesses were also 50% lower in parents who adopted kids when compared to other parents. From Oxford - Extending tamoxifen therapy can reduce risk of breast cancer recurrence, according to a report published in the Lancet. Researchers randomized nearly 7,000 breast cancer patients to either stop taking tamoxifen after 5 years of treatment or to continue taking the drug for 5 more years. Results showed that women who continued to take tamoxifen were less likely to have their cancer recur and die. Overall, there was a nearly 3% reduction in breast cancer mortality during the study period.

(December 7, 2012 - Insidermedicine) From Toronto - Glaucoma patients have delayed rapid eye movements, according to a report published in Eye and Brain. Researchers studied rapid eye movements in both people with glaucoma and those without the condition. Participants wore a device mounted on their head that measured how long it took eyes to move from one point to another, how long it took the eyes to initiate movement and whether or not the eyes focused right away or did they miss their intended target. They found that those with glaucoma had about 15% slower rapid eye movement than those without the disease, even if they were in an earlier stage of the disease. These results may explain why glaucoma patients are at raised risk of suffering falls and car accidents

(December 7, 2012 - Insidermedicine) From St. Louis - Many breast cancer patients can benefit from already available drugs, according to a report presented at the San Antonio Breast Cancer Symposium. Researchers conducted a meta-analysis on 8 DNA studies comprised of nearly 1,500 breast cancer patients. 25 of these patients had the HER2 negative subtype. Laboratory results showed that these patients would benefit from already existing, highly effective anti-HER2 drugs that standard tests did not indicate they were candidates for.
