Viagra use and sexual risk among HIV-seropositive men who have sex with men.

Wednesday, March 28th, 2007

BACKGROUND: Viagra may be used medically to treat erectile dysfunction or used recreationally to enhance sexual performance. Little is known about predictors of Viagra use among HIV-seropositive (HIV+) men who have sex with men (MSM), whether it is used with contraindicated substances, and the relationship with sexual risk. METHODS: A community-based sample of 1168 HIV+ MSM (55% men of color) from two large cities in the U.S. completed an A-CASI interview about their sexual practices and substance use in the past 3 months. In univariate analyses, Viagra use was associated with demographics, health status, substance use, and sexual risk. Logistic regression was conducted to predict Viagra use, with significant univariate predictors entered. RESULTS: One in eight men (12%) used Viagra, and many reported using contraindicated illicit substances (inhalants=53%) or HIV medications (indinavir=19%). In logistic regression, predictors of Viagra use were being older (OR, 1.06, 95% CI, 1.03-1.09), having education beyond high school (OR, 2.25, 95% CI, 1.16-4.36), taking HIV medications (OR, 1.98, 95% CI, 1.05-3.72), using any illicit substance (OR, 1.92, 95% CI, 1.16-3.18), using ketamine (OR, 2.82, 95% CI, 1.09-7.32), engaging in unprotected oral insertive intercourse (UOI) with HIV-negative or unknown serostatus non-main partners (OR, 1.88, 95% CI, 1.15-3.09), and engaging in unprotected anal insertive intercourse (UAI) with HIV-positive non-main partners (OR, 2.39, 95% CI, 1.33-4.31). CONCLUSIONS: Many HIV+ MSM used Viagra, particularly substance using men. Use of contraindicated illicit and prescribed medications was common. Viagra use was associated with UOI (but not UAI) with non-main partners who might be at risk of contracting HIV. With HIV+ non-main partners, Viagra users were more likely to engage in UAI. Providers should educate HIV+ Viagra users about potential interactions with other substances and provide counseling to reduce HIV and STD risks. Publication Types:

Junior doctors protest over jobs

Monday, March 19th, 2007

Junior doctors have marched in London and Glasgow to protest against reforms to their medical training. They claim their careers are being held back by a “badly-organised” online application system and too few specialist jobs to apply for.

Addressing the London protest, Tory leader David Cameron said the online system was an “utter shambles”.

Health Minister Lord Hunt admitted there had been “teething problems” with the system but promised to fix them.

‘Absolute disaster’

The online questionnaire-based application, called Modernising Medical Careers (MMC), was designed to speed up the process for placing junior doctors in specialist jobs.

But a catalogue of complaints has emerged.

Doctors say the forms are badly worded, do not ask pertinent questions, do not allow them to set out relevant qualifications and experience, and have no facility for attaching a CV.

The result, they say, is that the best candidates are not being selected for the right jobs.

Moderate drinking may benefit elderly men

Tuesday, March 6th, 2007

Older men who drink moderate amounts of alcohol may function better physically than either those who abstain completely or those who abuse alcohol, a new study suggests.

Moderate drinkers tend to be healthier in general than teetotalers or problem drinkers, Dr. Peggy M. Cawthon of California Pacific Medical Center in San Francisco and colleagues note. There is also evidence that moderate drinking may reduce inflammation.

Cawthon and colleagues compared functional limitations, physical performance and drinking history for 5,962 men aged 65 or older who were classified into 5 categories. Men who consumed 5 or more drinks on most days were classified as having a history of sustained excessive drinking, while those who responded positively to a questionnaire used to diagnose alcoholism were classified as problem drinkers.

Moderate drinkers were those who consumed between 7 and 20 drinks per week and heavy drinkers were men who consumed 21 or more drinks weekly. Abstainers made up the final group.

Moderate drinkers scored about 3 percent to 5 percent better on tests of physical function than the abstainers, the researchers found, while scores for heavy drinkers were about the same as those for the abstainers.

The abstainers were the most likely to report physical limitations to activities of daily living like walking, climbing stairs, and doing heavy housework. The heavy alcohol users were only slightly less likely than abstainers to have these limitations.

Low-moderate users, meaning men who drank between seven and 14 drinks a week, were the least likely to have functional limitations, and were at 38 percent lower risk of having these problems than abstainers.

The researchers call for more detailed studies to determine how alcohol use over time affects how functional status changes with age.

US Consumer Group Seeks to Ban Crestor

Monday, March 5th, 2007

Public Citizen Advocacy Group Petitions FDA to Ban Crestor

Citing seven cases of life-threatening rhabdomyolysis (muscle destruction) and nine cases of kidney failure or kidney damage in patients using low doses of Crestor, US consumer advocacy group Public Citizen petitioned the FDA to ban the cholesterol-lowering drug Crestor from the market. According to Public Citizen’s Dr. Sidney Wolfe, “Crestor has no unique advantage, but some unique risks” over other statins, such as an ability to cause primary kidney damage including failure. Two health insurers agree:

Two major U.S. insurers, WellPoint/Blue Cross, with 15 million patients insured, and Group Health Cooperative of Puget Sound (GHCPS) with more than 500,000 members have refused to reimburse for Crestor. “We’ve already been Baycolled,” said Dr. Robert Seidman, chief pharmacy officer for the Thousand Oaks, Calif.-based WellPoint. “There is a level of nervousness, and we’re being conservative and we’re being cautious,” Seidman also said.

Baycol, or cerivastatin, was banned after 31 cases of fatal rhabdomyolysis, none of which were seen prior to approval. In contrast, there were seven cases of rhabdomyolysis in patients receiving Crestor (rosuvastatin) before its approval. All were receiving a dose of 80 milligrams, which was not approved by the FDA, but as Public Citizen points out, “a small patient getting even the 40 milligram dose might be receiving the same amount of drug per pound of body weight and we were concerned that cases would occur at this 40 milligram dose or even lower doses.”

More recently, Medco Health Solutions has decided not to reimburse for Crestor and United Health Care has placed Crestor in the highest tier of three out-of-pocket categories to discourage use of Crestor.

Crestor, or rosuvastatin, which was approved by the FDA in August 2003, is marketed by AstraZeneca as a “super-statin” because it is the strongest of all statins currently on the market, a point which concerns Public Citizen:

Bayer withdrew cerivastatin in August, 2001, after the occurrence of unexpected cases of fatal rhabdomyolysis. The 80 mg dose of rosuvastatin was withdrawn by AstraZeneca because of safety concerns. Some critics are even anxious about the 40 mg dose. The finding of proteinuria [protein in the urine] and microscopic haematuria [blood in the urine] associated with rosuvastatin use are additional worries. Since there are no reliable data about efficacy [that is, actually decreasing heart attacks and strokes, not merely lowering cholesterol levels] and safety–and AstraZeneca is facing unusually acute commercial pressure to force rosuvastatin into the market–doctors should pause before prescribing this drug. Physicians must tell their patients the truth about rosuvastatin–that, compared with its competitors, rosuvastatin has an inferior evidence base supporting its safe use. AstraZeneca has pushed its marketing machine too hard and too fast.

Public Citizen says that in the past it has been instrumental in inducing the FDA to remove products such as Rezulin (diabetes drug) and Redux (weight loss drug) from the market.
