Colossal left main to right atrium fistula ligation complicated by left circumflex STEMI.

Congenital left main (LM) coronary artery to right atrium fistulas with progression to aneurysm development are rare. Most patients remain asymptomatic, but for those with progressive symptoms, intervention is required. However, there are potential life-threatening complications associated with surgical intervention. We present a case of an extremely rare markedly aneurysmal LM to right atrial fistula treated with surgical ligation complicated by inferolateral ST-elevation myocardial infarction several days post-operatively treated successfully using mechanical aspiration thrombectomy, a stent-retriever, balloon angioplasty, and subsequent intravascular ultrasound-guided percutaneous coronary intervention with drug-eluting stent.

Attitudes toward methamphetamine use and HIV risk behavior in men who have sex with men.

BACKGROUND AND OBJECTIVES: Methamphetamine use has been strongly associated with high-risk sexual behaviors, and its use has been increasing among men who have sex with men (MSM). Although the behavioral implications of methamphetamine use and sexual risk have been broadly examined, fewer studies have examined attitudes about methamphetamine use. METHODS: This study investigates the relationship between personal beliefs regarding methamphetamine use, patterns of use, and sexual risk behaviors within a sample of MSM attending a gay pride event (N= 342). RESULTS: A minority of MSM reported lifetime (27%) or recent (7%) methamphetamine use. Only a minority of MSM who had used methamphetamine believed that it enhanced sexual pleasure (32%) or incorporated methamphetamine use into their sexual activity (31%). Individuals who used methamphetamine during sexual activity were more likely to be recent users of the drug and more likely to engage in high-risk behaviors. A significant minority of participants endorsed items assessing the disinhibiting effects of methamphetamine including being less likely to use a condom (35%) and less selective in their choice of partners (26%). CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: Results suggest that prevention efforts may benefit from targeting the minority of methamphetamine users who perceive methamphetamine as enhancing sexual activity and use it for this purpose.

Misleading sexual partners about HIV status among persons living with HIV/AIDS.

Most people living with HIV/AIDS (PLWHA) disclose their serostatus to their sexual partners and take steps to protect their partners from HIV. Prior research indicates that some PLWHA portray themselves to their sexual partners as HIV-negative or otherwise misrepresent their HIV status. The aim of this study was to document the prevalence of misleading sexual partners about HIV status and to identify factors associated with misleading. A sample of 310 PLWHA completed a self-administered questionnaire assessing demographic information, disclosure, HIV knowledge, HIV altruism, psychopathy, and sexual risk behavior. Participants were also asked "Since you were diagnosed as having HIV, have you ever misled a sexual partner about your HIV status?" Overall, 18.6% of participants indicated that they had misled a sexual partner. Those who had misled a partner at some point since their diagnosis reported more current HIV transmission risk behaviors, including unprotected anal or vaginal sex with a partner who was HIV-negative or whose HIV status was unknown. Participants who had misled a partner did not differ from those who had not in terms of demographic characteristics. Individuals who had misled a partner scored significantly lower on a measure of HIV knowledge than those who had not misled a partner. HIV altruism and psychopathy were associated with sexual risk behavior, but did not differ between those who had misled and those who had not. Disclosure of HIV status can reduce HIV transmission, but only if people are candid. Interventions aimed at increasing knowledge and accurate disclosure may reduce the spread of HIV.

The Use of the Internet to Meet Sexual Partners: A Comparison of Non-Heterosexually-Identified Men with Heterosexually-Identified Men and Women.

In 2008, we conducted online interviews with 65 self-identified adult heterosexual men and women and gay/bisexual men to explore perceptions and experiences with meeting people online. Reasons for meeting people online, desired partner characteristics, and the process of connecting for sex paralleled those observed in real-life; but the Internet allowed people to identify more partners and specific partner characteristics. "Background checks" of online partners, even though often believed to be false, increased familiarity and trust leading to reduced perceived need for condom use. Participants said online condom use negotiation was easier, but usually occurred in face-to-face contexts in practice. (99).

The Feasibility of Interventions to Reduce HIV Risk and Drug Use among Heterosexual Methamphetamine Users.

This paper reports on a feasibility study that examined contingency management among out-of-treatment, heterosexual methamphetamine users and the reduction of drug use and HIV risk. Fifty-eight meth users were recruited through street outreach in Denver from November 2006 through March 2007. The low sample size reflects that this was a pilot study to see if CM is feasible in an out-of-treatment, street-recruited population of meth users. Secondary aims were to examine if reductions and drug use and risk behavior could be found. Subjects were randomly assigned to contingency management (CM) or CM plus strengths-based case management (CM/SBCM), with follow-up at 4 and 8 months. Participants were primarily White (90%), 52% male and averaged 38 years old. Eighty-three percent attended at least one CM session, with 29% attending at least fifteen. All participants reduced meth use significantly at follow-up. Those who attended more sessions submitted more stimulant-free urines than those who attended fewer sessions. Participants assigned to CM/SBCM attended more sessions and earned more vouchers than clients in CM. Similarly, participants reported reduced needle-sharing and sex risk. Findings demonstrate that CM and SBCM may help meth users reduce drug use and HIV risk.
