Abstract
This article describes and reviews the findings of several well-designed and controlled outcome trials of HIV prevention interventions that have been undertaken with men who have sex with men. The interventions reviewed have been of two types: face-to-face group or workshop interventions and community-level programs undertaken in gay communities. Both have shown robust effectiveness in promoting risk reduction behavior change among gay men and young people at risk for contracting HIV infection. Conclusions can now be reached about the benefits of these types of interventions. However, there remains an urgent need to develop and tailor HIV prevention approaches that can promote the maintenance of behavior change; to reach community segments that remain vulnerable, especially young and minority men who have sex with men; and to address the changing context of the epidemic.

Abstract
The use of room temperature solutions for body cavity irrigation during surgical procedures can lead to the development of perioperative hypothermia. Hypothermia during this period causes patient discomfort, increases oxygen consumption, interferes with the clotting cascade, and increases the length of hospital stay. Perioperative hypothermia in anesthetized patients also contributes to extended sedation, delayed emergence, and prolonged recovery from neuromuscular blockade. Twenty-four adult American Society of Anesthesiologists (ASA) class I and II patients were randomly assigned to receive warmed arthroscopic irrigation solution or room-temperature irrigation solution in this randomized, prospective study. Tympanic temperatures were monitored every 15 minutes throughout the surgical and postanesthesia recovery periods. P < .05 was considered significant. Statistical comparison of the mean percent temperature decrease from preoperative baseline between the 2 groups did not support the hypothesis that patients receiving warmed irrigation solution would maintain a higher core body temperature than those receiving room temperature solution.

Abstract
PURPOSE To describe the abdominal computed tomographic (CT) and ultrasonographic (US) findings in patients with thoracic lymphangioleiomyomatosis (LAM) and to relate the prevalence of the findings to the severity of pulmonary disease. MATERIALS AND METHODS Eighty patients with LAM underwent chest and abdominopelvic CT and abdominopelvic US. The images were reviewed prospectively by one radiologist, and the abdominal findings were recorded and correlated with the severity of pulmonary disease at thin-section CT. RESULTS Sixty-one (76%) of 80 patients had positive abdominal findings. The most common abdominal findings included renal angiomyolipoma (AML) in 43 patients (54%), enlarged abdominal lymph nodes in 31 (39%), and lymphangiomyoma in 13 (16%). Less common findings included ascites in eight (10%), dilatation of the thoracic duct in seven (9%), and hepatic AML in three (4%). A significant correlation (P =.02) was observed between enlarged abdominal lymph nodes and increased severity of lung disease. CONCLUSION There are characteristic abdominal findings in patients with LAM that, in conjunction with the classic thin-section CT finding of pulmonary cysts, are useful in establishing this diagnosis.

Abstract
OBJECTIVES AIDS service organizations (ASOs) rarely have access to the information needed to implement research-based HIV prevention interventions for their clients. We compared the effectiveness of 3 dissemination strategies for transferring HIV prevention models from the research arena to community providers of HIV prevention services. METHODS Interviews were conducted with the directors of 74 ASOs to assess current HIV prevention services. ASOs were randomized to programs that provided (1) technical assistance manuals describing how to implement research-based HIV prevention interventions, (2) manuals plus a staff training workshop on how to conduct the implementation, or (3) manuals, the training workshop, and follow-up telephone consultation calls. Follow-up interviews determined whether the intervention model had been adopted. RESULTS The dissemination package that provided ASOs with implementation manuals, staff training workshops, and follow-up consultation resulted in more frequent adoption and use of the research-based HIV prevention intervention for gay men, women, and other client populations. CONCLUSIONS Strategies are needed to quickly transfer research-based HIV prevention methods to community providers of HIV prevention services. Active collaboration between researchers and service agencies results in more successful program adoption than distribution of implementation packages alone.

Abstract
Evidence indicates that neuronally released thyrotropin-releasing hormone (TRH) is selectively inactivated by TRH-degrading ectoenzyme (TRH-DE) (EC ). TRH-DE inhibitors may be used to enhance the therapeutic actions of TRH and to investigate the functions of TRH and TRH-DE in the central nervous system. Although TRH-DE appears to exhibit a high degree of specificity toward TRH, systematic specificity studies, which would facilitate inhibitor design, have not been previously conducted for this enzyme. In this paper we present the first description of TRH-DE specificity across a directed peptide library in which the histidyl (P(1)') residue of TRH was replaced by a series of amino acids. Peptides were synthesized using standard solid phase chemistry. Kinetic parameters were measured either by continuous or discontinuous fluorometric assays or by quantitative high pressure liquid chromatography. The P(1)' residue was found to influence significantly both the ability of the peptides to bind to TRH-DE, as measured by their K(i) values, and the ability of TRH-DE to catalyze their hydrolysis. Moderately bulky, uncharged P(1)' residues were found to bind preferentially to TRH-DE. Results from this screen provide valuable information for the development of TRH-DE inhibitors and have led to the identification of two potent, reversible TRH-DE inhibitors, l-pyroglutamyl-l-asparaginyl-l-prolineamide (K(i) = 17.5 micrometer) and Glp-Asn-Pro-7-amido-4-methyl coumarin (K(i) = 0.97 micrometer).

Abstract
Small-group HIV prevention interventions that focus on individual behavioural change have been shown to be especially effective in reducing HIV risk among persons with severe mental illness. Because economic resources to fund HIV prevention efforts are limited, health departments, community planning groups and other key decision-makers need reliable information on the cost and cost-effectiveness (not solely on effectiveness) of different HIV prevention interventions. This study used an economic evaluation technique known as cost-utility analysis to assess the cost-effectiveness of three related cognitive-behavioural HIV risk reduction interventions: a single-session, one-on-one intervention; a multi-session small-group intervention; and a multi-session small-group intervention that taught participants to act as safer sex advocates to their peers. For men, all three interventions were cost-effective, but advocacy training was the most cost-effective of the three. For women, only the single-session intervention was cost-effective. The gender differences observed here highlight the importance of focusing on gender issues when delivering HIV prevention interventions to men and women who are severely mentally ill.

Abstract
To examine influences of medical factors (e.g., viral load) and nonmedical factors (e.g., patient characteristics) on treatment decisions for highly active antiretroviral therapy (HAART), we sent a survey to a random sample of 995 infectious disease physicians who treat patients with HIV/AIDS in the United States in August, 1998. The response rate was 53%. Respondents were asked to report their current practices with respect to antiretroviral treatment and the extent to which each of three medical and 17 nonmedical factors would influence them for or against prescribing HAART to a hypothetical HIV-positive patient. Most reported initiating HAART with findings of low CD4+ cell counts and high viral loads, and weighing CD4+ cell counts, viral load, and opportunistic infection heavily in their decisions to prescribe HAART. Patients' prior history of poor adherence was weighed very much against initiating HAART. Patient homelessness, heavy alcohol use, injection drug use, and prior psychiatric hospitalization were cited by most physicians as weighing against HAART initiation. Thus, most physicians in this sample follow guidelines for the use of HAART, and nonmedical factors related to patients' life situations are weighed as heavily as disease severity in treatment decisions. As HIV increasingly becomes a disease associated with economic disadvantage and other social health problems, it will be essential to develop interventions and care support systems to enable patients experiencing these problems to benefit from HIV treatment advances.

Abstract
New treatments for HIV can improve immune functioning and decrease mortality. However, lapses in adherence may render these complex regimens ineffective. Sixty-three men and 9 women on highly active antiretroviral therapy completed measures of medication adherence, psychological characteristics, and barriers to adherence. HIV viral load, a health outcome measure of virus amount present in blood, was also obtained. The sample was 36% African American and 56% Caucasian, with 35% reporting disability. Nearly one third of patients had missed medication doses in the past 5 days, and 18% had missed doses weekly over the past 3 months. Frequency of missed doses was strongly related to detectable HIV viral loads. Depression, side-effect severity, self-efficacy, and social support distinguished patients with good and poor adherence. Barriers also varied with adherence level. Implications for interventions promoting HIV treatment adherence are discussed.

Abstract
Young men who have sex with men (YMSM), and particularly ethnic minority YMSM, experience high incidence HIV infection due to continued patterns of high-risk sexual behaviour. The intent of this research was to systematically solicit input and recommendations from YMSM themselves concerning the kinds of HIV prevention programmes that would best meet their needs and would address risk issues they believed are critical. In-depth qualitative interviews were conducted with a sample of 72 purposively selected YMSM to identify necessary components of HIV prevention targeting YMSM. Respondents noted a need for comprehensive HIV prevention programmes that addressed issues related to dating and intimacy, sexuality and arousal, drugs and alcohol, self-esteem and self-worth, abuse and coercion, and sexual identity. Respondents emphasized the importance of keeping programmes confidential, fun, comfortable, accepting and open to all YMSM regardless of sexual identity. Identified community resource needs included safe havens for youth, more peer educators and older MSM mentors, increased school-based sexuality education, and greater support from the society at large as well as from churches, the gay community and communities of Color. Implications of these findings for HIV prevention are discussed.

Abstract
Eastern Europe is experiencing increased rates of HIV/AIDS, and the Russian Federation is among the countries with the most alarming case rate increases. Behavioural and biological studies demonstrate that the transmission of HIV in Russia is occurring as a result of injection drug use, homosexual, and heterosexual risk behaviours. Factors that promote risk and therefore enable HIV transmission in Russia parallel those found in other countries, including epidemics of other sexually transmitted infections, economic instability, poverty, and social factors such as gender roles. Research is urgently needed to better understand and forecast the HIV epidemic in Russia, as well as to develop effective interventions to prevent a Russian AIDS crisis.

Abstract
The public health objective of preventing new HIV infections can be achieved only through effective information exchange among service providers, researchers, and policymakers. The potential for successful transfer of research-based HIV prevention technology to service providers will be enhanced if investigators take into account in the research planning stage how interventions will be used in the field, seek early input from community members and service providers, test variations of interventions that may increase their practicality in applied settings, and determine the cost and effectiveness of intervention delivery. Strategies are needed to ensure that the experiences of service providers help to inform the HIV prevention research agenda, improve service organization infrastructure and capacity development, and facilitate organizational networking so that providers can use new-generation HIV prevention interventions. Policies are needed to facilitate the development of intervention packages, training, and ongoing technical assistance for service providers in implementing effective HIV prevention interventions.

Abstract
Many of the diseases that cause premature illness and death--including some cancers, heart disease, and AIDS--could be prevented if persons made behavior changes to reduce their risk for developing the illnesses. Over the past two decades, there have been great advances in our scientific understanding of how to promote health risk behavior change. This paper briefly reviews elements and examples of effective behavior change interventions, including programs that can be offered in service settings as well as community-level interventions. The prevention of diseases through behavioral public health interventions requires the investment of funds but can reduce burdens on health care systems, reduce the human toll caused by premature deaths, and be highly cost-effective. A remarkable number of diseases could be prevented if individuals were effectively assisted in changing the risk behaviors responsible for those illnesses. The causal association between cigarette smoking and lung cancer, other pulmonary diseases, and cardiovascular disease is well-known, and millions of premature deaths could be prevented if people stopped smoking cigarettes. Deaths due to cardiovascular disease could be dramatically reduced if persons made behavioral and lifestyle changes to improve their fitness through exercise, obesity reduction, and maintenance of low blood cholesterol levels. The World Health Organization estimates that over 45 million persons worldwide have already contracted HIV infection, and nearly 1 million of these cases are in the United States. Over 40,000 Americans continue to contract HIV infection each year. Virtually every new case of HIV infection is preventable if individuals at risk made changes in their sexual or drug use practices. While lung cancer, cardiovascular disease, and AIDS are three of the clearest examples, persons' behavior plays a direct or a contributing role in the development of many other diseases that cause premature death or that worsen health and life quality. Recognition of the link between behavior and preventable illness--and recognition that enormous health, economic, and quality of life benefits could be realized through healthier behavior patterns--is not new. We have known all of this for a long time. We have also known for a very long time that helping people to successfully change risky behavior habits is often very difficult. Over the past 20 years, a field of scientific study and applied practice has developed with the purpose of better understanding why persons engage in health risk behavior patterns and developing approaches to help people change these patterns. Under the rubric of "behavioral medicine", this field makes use of behavioral science theory and behavior change techniques applied to health and disease prevention.

Abstract
This article examines the role of technical assistance (TA) in supporting the replication of proven HIV interventions. A case study of the replication of the VOICES/VOCES intervention elucidates the level and types of TA provided to support new users through the adoption process. TA included help in garnering administrative support, identifying target audiences, recruiting groups for sessions, maintaining fidelity to the intervention's core elements, tailoring the intervention to meet clients' needs, strengthening staff members' facilitation skills, troubleshooting challenges, and devising strategies to sustain the intervention. Two to four hours per month of TA were provided to each agency adopting the intervention, at an estimated monthly cost of $206 to $412. Findings illustrate how TA supports replication by establishing a conversation between the researcher TA providers experienced with the intervention and new users. This communication helps preserve key program elements and contributes to ongoing refinement of the intervention.

Abstract
Effective orientation and training are fundamental to the successful implementation of any intervention because they communicate the critical first impressions of the intervention and the skills needed to conduct it. When research-based HIV prevention interventions are translated into practice, issues arise that require adaptation and expansion of the basic functions of orientation and training. This article identifies some of these issues by drawing on the experience of researchers in the Replicating Effective Programs (REP) project. The purpose, structure, and instructional approach of the orientation and training for administrators, staff, and volunteers are described in depth for one project, with comparisons and additional examples from others. Based on these descriptions, critical issues for orientation and training for replication are presented. These include extending orientation and training to a broad audience within the adopting agency, allocating sufficient time to ensure understanding of the intervention, and planning for staff turnover.

Abstract
Many community-based organizations and health departments want to implement HIV prevention interventions with scientifically demonstrated effectiveness. The Replicating Effective Programs (REP) project supported researchers in developing intervention packages designed to help prevention partners replicate effective programs in their settings. Intervention packages convey the intervention's foundation, components, and methods and are one part of a larger system needed to transfer research-based HIV prevention technology to service providers. Implementation packages were developed using a multistage process. The original researchers drafted the materials, advisory groups reviewed the packages, and adopting agencies used the materials in trial runs. The advisory groups and adopting agencies recommended extensive use of examples, thorough explanations about the rationale for each intervention component, explicit representation of people of color in the materials, clear statements about the intended audience(s), and an easy-to-use and visually appealing format. Packages were revised based on these recommendations and the outcomes of the trial runs.

Abstract
Long-term collaborations among researchers, staff and volunteers in community-based agencies, staff in institutional settings, and health advocates present challenges. Each group has different missions, procedures, attributes, and rewards. This article reviews areas of potential conflict and suggests strategies for coping with these challenges. During the replication of five effective HIV prevention interventions, strategies for maintaining mutually beneficial collaborations included selecting agencies with infrastructures that could support research-based interventions; obtaining letters of understanding that clarified roles, responsibilities, and time frames; and setting training schedules with opportunities for observing, practicing, becoming invested in, and repeatedly implementing the intervention. The process of implementing interventions highlighted educating funders of research and public health services about (a) the costs of disseminating interventions, (b) the need for innovation to new modalities and theories for delivering effective interventions, and (c) adopting strategies of marketing research and quality engineering when designing interventions.

Abstract
HIV prevention research interventions usually follow protocols with specific procedures. If a community-delivered intervention uses the same procedures with the same populations as those in the original research, the behavior change effects should be similar. However, community-based providers may not replicate an intervention exactly as it was conducted in the effectiveness study. Adaptation may be needed to better meet the needs of the clients, community, or organization. We propose that interventions can be defined in terms of core elements likely to be responsible for effectiveness. These core elements cannot be changed without fundamentally changing the intervention, whereas other characteristics may be modified without altering effectiveness. HIV prevention researchers and service providers can collaborate to develop interventions that not only are effective but can also be successfully implemented by service organizations. If researchers actively involve service providers and community members in intervention planning, technology transfer goals can be better achieved.

Abstract
OBJECTIVES Women in impoverished inner-city neighborhoods are at high risk for contracting HIV. A randomized, multisite community-level HIV prevention trial was undertaken with women living in 18 low-income housing developments in 5 US cities. METHODS Baseline and 12-month follow-up population risk characteristics were assessed by surveying 690 women at both time points. In the 9 intervention condition housing developments, a community-level intervention was undertaken that included HIV risk reduction workshops and community HIV prevention events implemented by women who were popular opinion leaders among their peers. RESULTS The proportion of women in the intervention developments who had any unprotected intercourse in the past 2 months declined from 50% to 37.6%, and the percentage of women's acts of intercourse protected by condoms increased from 30.2% to 47.2%. Among women exposed to intervention activities, the mean frequency of unprotected acts of intercourse in the past 2 months tended to be lower at follow-up (mean = 4.0) than at baseline (mean = 6.0). These changes were corroborated by changes in other risk indicators. CONCLUSIONS Community-level interventions that involve and engage women in neighborhood-based HIV prevention activities can bring about reductions in high-risk sexual behaviors.

Abstract
Most persons aware of their HIV-positive serostatus refrain from sexual behavior that could transmit HIV infection to others. However, a minority of men who test HIV-seropositive continue to engage in transmission risk behavior. One factor that may play a role in high-risk sexual activity involves sexual behavior self-management. The present study investigated the role of sexual compulsivity as a contributing factor to high-risk sexual behavior in HIV seropositive men who have sex with men (N = 112). Participants also completed measures of factors known to be related to risky sexual behavior including: personal substance use, sexual partner substance use, pleasure associated with high-risk activities, beliefs about transmission risks, intentions to avoid future instances of risky behavior, and self-esteem. Men scoring high on sexual compulsivity reported engaging in more frequent unprotected sexual acts with more partners, reported greater use of cocaine in conjunction with sexual activity, rated high-risk sexual acts as more pleasurable, and reported lower self-esteem. Mediational analyses indicated that the relationship between sexual compulsivity and high-risk sexual behavior was partially mediated by both personal cocaine use and partner cocaine use in conjunction with sexual activity. The results suggest a need to integrate HIV risk-reduction services and substance use treatment for those persons living with HIV who have difficulty avoiding transmission risk behavior.

Thyrotropin-releasing hormone degrading-ectoenzyme (TRH-DE) (EC 3.4. 19.6), removes the N-terminal pyroglutamyl residue of thyrotropin-releasing hormone (TRH). Discontinuous assays have been used to measure TRH-DE activity; however, a continuous assay is needed to make reliable measurements of initial rates and facilitate kinetic studies. Presented is a continuous, coupled enzyme assay for TRH-DE in which TRH-DE hydrolyzed the substrate, pyroglutamyl-histidyl-prolylamido-4-methyl coumarin (TRHMCA), to give His-ProMCA, which was then cleaved by dipeptidyl peptidase IV (EC 3.4.14.5) to give 7-amino-4-methyl coumarin (MCA). Reaction progress was monitored continuously by measuring the increase in MCA fluorescence. This assay should be especially useful for rapid screening of potential TRH-DE inhibitors. A previously reported discontinuous assay, where nonenzymatic cyclization at 80 degrees C was used to liberate MCA from His-ProMCA, was found to underestimate the amount of product formed. A modified procedure that avoids this is presented. Initial rates and kinetic parameters for TRHMCA hydrolysis by TRH-DE determined using this modified assay correspond with those determined by the continuous assay. Discontinuous and continuous assays gave K(m) values for TRHMCA of 3.4 +/- 0.7 microM (n = 5) and 3.8 +/- 0.5 microM (n = 5), respectively. K(i) values determined by the discontinuous assay for TRH and TRH-OH were 35 +/- 4 microM (n = 3) and 311 +/- 31 microM (n = 5), respectively.

Abstract
Penicillin G acylase is an important enzyme in the commercial production of semisynthetic penicillins used to combat bacterial infections. Mutant strains of Providencia rettgeri were generated from wild-type cultures subjected to nutritional selective pressure. One such mutant, Bro1, was able to use 6-bromohexanamide as its sole nitrogen source. Penicillin acylase from the Bro1 strain exhibited an altered substrate specificity consistent with the ability of the mutant to process 6-bromohexanamide. The X-ray structure determination of this enzyme was undertaken to understand its altered specificity and to help in the design of site-directed mutants with desired specificities. In this paper, the structure of the Bro1 penicillin G acylase has been solved at 2.5 A resolution by molecular replacement. The R-factor after refinement is 0.154 and R-free is 0.165. Of the 758 residues in the Bro1 penicillin acylase heterodimer (alpha-subunit, 205; beta-subunit, 553), all but the eight C-terminal residues of the alpha-subunit have been modeled based on a partial Bro1 sequence and the complete wild-type P. rettgeri sequence. A tightly bound calcium ion coordinated by one residue from the alpha-subunit and five residues from the beta-subunit has been identified. This enzyme belongs to the superfamily of Ntn hydrolases and uses Ogamma of Ser beta1 as the characteristic N-terminal nucleophile. A mutation of the wild-type Met alpha140 to Leu in the Bro1 acylase hydrophobic specificity pocket is evident from the electron density and is consistent with the observed specificity change for Bro1 acylase. The electron density for the N-terminal Gln of the alpha-subunit is best modeled by the cyclized pyroglutamate form. Examination of aligned penicillin acylase and cephalosporin acylase primary sequences, in conjunction with the P. rettgeri and Escherichia coli penicillin acylase crystal structures, suggests several mutations that could potentially allow penicillin acylase to accept charged beta-lactam R-groups and to function as a cephalosporin acylase and thus be used in the manufacture of semi-synthetic cephalosporins.

Abstract
Community-based AIDS service organizations (ASOs) are important providers of HIV prevention services in cities throughout the United States. This study examined the types of HIV prevention programs that are being undertaken by ASOs and assessed the kinds of new programs that ASOs feel are needed as the HIV epidemic continues to evolve. Factors that will need attention as new HIV prevention programs are developed by ASOs include high turnover of personnel in the organizations, capacity building that will be needed for ASOs to offer more intensive or specialized programs, and strategies to provide technical assistance as ASOs develop new types of programs.

Abstract
The public health benefits of needle exchange programs (NEPs) are well known. NEPs lower risk factors for HIV transmission by providing injection drug users (IDUs) with clean syringes and needles; harm reduction materials; and referrals to drug, sexually transmitted disease, mental health, and medical treatment facilities. While exchange programs continue to be implemented, there have been few reports illustrating how social science and community assessment research can be used to guide the development of NEPs. Using the Lifepoint needle exchange program in Milwaukee as a case study, this paper shows how social science methods can be used to understand IDU culture through the community identification process, link qualitative and observational findings to program decision making, and guide the implementation and operation of a needle exchange. The community identification process showed that there were different IDU subcultures in the city indicating that the NEP would need to be tailored to meet the distinctive needs of multiple drug use networks. Ethnographic field observations and key informant and systems representative interviews resulted in a two-stage NEP planning process that included a community task force on IDUs and of the development of methods to operationalize community assessment findings into the operating plan of the NEP. This process illustrates the importance of integrating a systematic community analysis in the planning of a NEP.
