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.

(August 27, 2013 - Insidermedicine) From Australia - Ranibizumab treatment for patients with diabetic macular edema improves visual function, according to a report published in JAMA Ophthalmology. Researchers studied over 300 patients with diabetic macular deem. Participants were randomized to either ranibizumab plus sham laser, ranibizumab plus laser, or sham injections plus laser. Injections and sham injections were given for 3 months and then as needed, while laser and sham laser were given at baseline and then as needed. Participants had their visual function assessed at 0, 3 and 12 months. Results showed that the ranibizumab plus laser group showed the greatest improvement in their visual function, followed by the ranibizumab only group and then the laser only group.

(August 27, 2013 - Insidermedicine) From Boston - A new report published in JAMA identifies a genetic variant that may raise risk of heart disease in type 2 diabetics. Researchers reviewed data from several long term studies. In particular, they examined data on over 4,000 diabetic patients--1,500 who had heart disease and 2,600 who did not. After testing over 2.5 million genetic variants, researchers found a variant that consistently raised risk of heart disease in diabetes patients by 36%.

(August 27, 2013 - Insidermedicine) From the UK - Broccoli may help prevent osteoarthritis, according to a report published in Arthritis and Rheumatism. Researchers conducted an animal study on a mouse model. Rodents were fed a normal diet or a diet high in sulforophane--a compound released when eating vegetables such as broccoli, brussels sprouts and cabbage. Results showed that mice that ate the diet high in sulforophane had significantly less cartilage damage than mice that ate a normal diet.

(August 26, 2013 - Insidermedicine) From Manitoba - According to research published in CMAJ, patients who leave the hospital against doctor's advice are at raised risk of readmission and death. Researchers reviewed nearly 2 million adult hospital admissions and discharges over the past 20 years. Of these, there were just over 20,000 patients who left the hospital against medical advice. Results showed that these patients had 3x the readmission rates within the following month--25% of whom returned within 1 day. Those who left the hospital against medical advice were also at 2.5x increased risk of death within 90 days.

(August 26, 2013 - Insidermedicine) From Florida - A new report published in PLOS ONE describes a novel approach that may revolutionize the treatment of melanoma. Researchers studied a mouse model of melanoma, injecting the rodents with a substance known as PV-10--a solution derived from Rose Bengal. Results showed that the single injection greatly reduced skin cancer lesions in the rodents and also reduced the size of tumours that had spread to the lungs. The solution produced produced a significant anti-tumor immune response.

(August 26, 2013 - Insidermedicine) From Texas - A new screening strategy may prevent many ovarian cancer deaths, according to a report published in Cancer. Researchers developed a screening strategy that measured changes in a blood protein known as CA125 (a known biomarker for the disease). Initially, researchers conducted annual blood tests on a group of 4,000 post-menopausal women. Women were then divided into three risk groups based on the results of these blood tests--low, intermediate or high. Women who were at intermediate risk underwent another blood test in three months, and those at high risk received a transvaginal ultrasound. Results showed that 10 women underwent surgery based on their ultrasounds, 4 of whom had ovarian cancer. The specificity of this strategy was 99.9% and all of the cancer discovered were in an early stage.

(August 23, 2013 - Insidermedicine) From Australia - According to a report published in Stroke, risk of stroke caused by smoking is similar for both men and women. Researchers conducted a meta-analysis, examining over 80 studies published between 1966 and 2013. Results showed that smoking increases the risk of any type of stroke in both men and women by 60-80%. Researchers also found that men and women smokers were both at a 50% increased risk of ischemic stroke, and that women had a 17% greater risk of hemorrhagic stroke.

(August 22, 2013 - Insidermedicine) From Boston - Repeat brain trauma suffered by athletes can affect their memory, mood and behaviour, according to a report published in Neurology. Researchers studied the brains of 36 male athletes, all of whom had been diagnosed with chronic traumatic encephalopathy (CTE) after their deaths. The athletes were between 17 and 98 years of age and had no other brain diseases. Most of the participants had played football, with the rest participating in hockey, boxing, and wrestling. Results showed that 22 of the athletes demonstrated mood and behaviour problems as their first symptoms of the disease, while 11 demonstrated memory and thinking problems as their first symptoms. Only 3 athletes had no symptoms at all.

(August 21, 2013 - Insidermedicine) From Texas - Poor oral health may be associated with cancer-causing HPV infections, according to a report published in Cancer Prevention Research. Researcher studied nearly 3,500 adults taking part in a long term study. Researchers reviewed data on participant's oral health--overall oral health, presence of gum disease, use of mouthwash to treat dental problems and number of teeth lost--and looked for the presence of low or high risk HPV types. Results showed that being male, smoking cigarettes and marijuana, and oral sex habits raised risk of an oral HPV infection. As well, overall oral health was found to be an independent risk factor for oral HPV--regardless of whether participants smoked or had multiple oral sex partners.
