Submission of vaginal samples collected at home could remove barriers that women face in getting screened for cervical cancer. From December 2013 to January 2014, women aged 21-30 years were recruited online to participate in either (1) self-collected testing for human papillomavirus (HPV) infection and an online survey, or (2) an online survey regarding their perceptions of self-collected testing for HPV infection. Demographics, risk factors, testing perceptions, and satisfaction with self-collected testing were assessed with online questionnaires. Women who performed self-collection were sent a home sampling kit by US mail, which was returned via US mail for HPV testing. A total of 197 women were enrolled, with 130 completing the online survey and 67 participating in both the survey and self-collection. Of the 67 women who were sent kits, 62 (92.5 %) were returned for testing. Sixty kits contained a sample sufficient for testing. The overall prevalence of HPV infection was 17.8 %, however 6 women (9.7 %) were infected with >1 type of HPV. Women who self-collected a sample reported more favorable attributes of self-collection compared to women who only participated in the online survey, including ease of sampling (87.1 vs. 18.9 %), no pain during sampling (72.6 vs. 5.6 %), and lack of embarrassment (67.7 vs. 12.9 %). A high prevalence of HPV infection was demonstrated among women recruited via the internet. Online recruitment and at home screening methods have the potential to engage women in screening by offering an approach that might be more acceptable to women of different backgrounds.

This study describes the results of an online social support intervention, called 'Thrive with Me' (TWM), to improve antiretroviral therapy (ART) adherence. HIV-positive gay or bisexually-identified men self-reporting imperfect ART adherence in the past month were randomized to receive usual care ( n = 57) or the eight-week TWM intervention ( n = 67). Self-reported ART outcome measures (0-100 % in the past month) were collected at baseline, post-intervention, and 1-month follow-up. Follow-up assessment completion rate was 90 %. Participants rated (1-7 scale) the intervention high in information and system quality and overall satisfaction (Means ≥ 5.0). The intervention showed modest effects for the overall sample. However, among current drug-using participants, the TWM (vs. Control) group reported significantly higher overall ART adherence (90.1 vs. 57.5 % at follow-up; difference = 31.1, p = 0.02) and ART taken correctly with food (81.6 vs. 55.7 % at follow-up; difference = 47.9, p = 0.01). The TWM intervention appeared feasible to implement, acceptable to users, and demonstrated greatest benefits for current drug users. [ABSTRACT FROM AUTHOR]

Purpose: To report a case of transvaginal small intestinal hernia following abdominal sacrocolpopexy and review this clinical presentation in the current literature. Methods: A review of our case and a literature review of vaginal evisceration were carried out. Results: The patient underwent sacrocolpopexy and a Burch procedure. Six months later, a recurrent enterocele through a 1 cm defect in the vaginal vault was diagnosed. Several weeks later she presented with an incarcerated and strangulated loop of small intestine extending beyond the introitus. This required an urgent exploratory laparotomy, ileocecal resection, and vaginal vault closure. Postoperatively, she experienced gradual prolapse recurrence and is currently successfully managed with a pessary. Risk factors that include vaginal atrophy, chronic constipation, and previous pelvic surgery may have contributed to the evisceration, mesh erosion, and may have caused the breakdown in the vaginal vault mucosa ultimately responsible for the evisceration. In addition, placement of the sacrocolpopexy mesh without tension, and utilization of an interposition graft to reinforce the weakened vaginal vault tissue, are aspects of the surgical procedure that may influence outcomes. At the time of evisceration repair, the best approach to resuspend the vaginal vault, and prevent recurrent prolapse or evisceration, is currently unknown. Conclusion: Vaginal evisceration is a potential complication of abdominal sacrocolpopexy. Early recognition and treatment of this complication is critical, and prolapse recurrence may occur even after surgical repair. [ABSTRACT FROM AUTHOR]

This study aimed to develop an empirically based description of relapse in Electronic Gaming Machine problem gambling. In this paper the authors describe part one of a two part, linked relapse process: the 'push' towards relapse. In this two-part process, factors interact sequentially and simultaneously within the problem gambler to produce a series of mental and behavioural events that ends with relapse when the 'push' overcomes 'pull' (part one); or as described in part two, continued abstinence when 'pull' overcomes 'push'. In the second paper, the authors describe how interacting factors 'pull' the problem gambler away from relapse. This study used four focus groups comprising thirty participants who were gamblers, gamblers' significant others, therapists and counsellors. The groups were recorded, recordings were then transcribed and analysed using thematic, textual analysis. With the large number of variables considered to be related to relapse in problem gamblers, five key factors emerged that 'push' the gambler towards relapse. These were urge, erroneous cognitions about the outcomes of gambling, negative affect, dysfunctional relationships and environmental gambling triggers. Two theories emerged: (1) each relapse episode comprised a sequence of mental and behavioural events, which evolves over time and was modified by factors that 'push' this sequence towards relapse and (2) a number of gamblers develop an altered state of consciousness during relapse described as the 'zone' which prolongs the relapse.

This study aimed to develop an empirically based description of relapse in Electronic Gaming Machine (EGM) problem gambling (PG) by describing the processes and factors that 'pull' the problem gambler away from relapse contrasted with the 'push' towards relapse. These conceptualisations describe two opposing, interacting emotional processes occurring within the problem gambler during any relapse episode. Each relapse episode comprises a complex set of psychological and social behaviours where many factors interact sequentially and simultaneously within the problem gambler to produce a series of mental and behaviour events that end (1) with relapse where 'push' overcomes 'pull' or (2) continued abstinence where 'pull' overcomes 'push'. Four focus groups comprising thirty participants who were EGM problem gamblers, gamblers' significant others, therapists and counsellors described their experiences and understanding of relapse. The groups were recorded, recordings were then transcribed and analysed using thematic textual analysis. It was established that vigilance, motivation to commit to change, positive social support, cognitive strategies such as remembering past gambling harms or distraction techniques to avoid thinking about gambling to enable gamblers to manage the urge to gamble and urge extinction were key factors that protected against relapse. Three complementary theories emerged from the analysis. Firstly, a process of reappraisal of personal gambling behaviour pulls the gambler away from relapse. This results in a commitment to change that develops over time and affects but is independent of each episode of relapse. Secondly, relapse may be halted by interacting factors that 'pull' the problem gambler away from the sequence of mental and behavioural events, which follow the triggering of the urge and cognitions to gamble. Thirdly, urge extinction and apparent 'cure' is possible for EGM gambling. This study provides a qualitative, empirical model for understanding protective factors against gambling relapse.

Online social media and mobile technologies hold potential to enhance adherence to antiretroviral therapy (ART), although little is known about the current use of these technologies among people living with HIV (PLWH). To address this gap in understanding, 312 PLWH (84% male, 69% White) US adults completed an online survey in 2009, from which 22 persons accepted an invitation to participate in one of two online focus groups. Results showed that 76% of participants with lower ART adherence used social networking websites/features at least once a week. Their ideal online social networking health websites included one that facilitated socializing with others (45% of participants) and ones with relevant HIV informational content (22%), although privacy was a barrier to use (26%). Texting (81%), and to a lesser extent mobile web-access (51%), was widely used among participants. Results support the potential reach of online social networking and text messaging intervention approaches. [ABSTRACT FROM AUTHOR]

Achieving satisfactory retention in online HIV prevention trials typically has proven difficult, particularly over extended timeframes. The overall aim of this study was to assess factors associated with retention in the Men's INTernet Study II (MINTS-II), a randomized controlled trial of a sexual risk reduction intervention for men who have sex with men. Participants were recruited via e-mails and banner advertisements in December, 2007 to participate in the MINTS-II Sexpulse intervention and followed over a 12-month period. Retention across the treatment and control arms was 85.2% at 12 months. Factors associated with higher retention included: randomization to the control arm, previous participation in a study by the research team, e-mail and telephone reminders to complete a survey once it was available online, and fewer e-mail contacts between surveys. The results provide evidence that achieving satisfactory retention is possible in online HIV prevention trials, and suggest best practices for maximizing retention. [ABSTRACT FROM AUTHOR]

The article analyzes the future of Internet-based human immunodeficiency virus (HIV) prevention. It stresses the need for technology-based HIV prevention interventions, as Internet gay sex sites, Internet porn sites, and gay virtual communities continue to exist to serve as venue for men who have sex with men (MSM) to meet. The identification of computer-assisted survey interviews (CASI) is regarded a key development in behavioral research. However, there are concerns about human subjects protections, data security and access to technologies.

Virtually all quantitative microdata used by social scientists derive from samples that incorporate clustering, stratification, and weighting adjustments (Kish 1965, 1992). Such data can yield standard error estimates that differ dramatically from those derived from a simple random sample of the same size. Researchers using historical U.S. census microdata, however, usually apply methods designed for simple random samples. The resulting p values and confidence intervals could be inaccurate and could lead to erroneous research conclusions. Because U.S. census microdata samples are among the most widely used sources for social science and policy research, the need for reliable standard error estimation is critical. We evaluate the historical microdata samples of the Integrated Public Use Microdata Series (IPUMS) project from 1850 to 1950 in order to determine (1) the impact of sample design on standard error estimates, and (2) how to apply modern standard error estimation software to historical census samples. We exploit a unique new data source from the 1880 census to validate our methods for standard error estimation, and then we apply this approach to the 1850-1870 and 1900-1950 decennial censuses. We conclude that Taylor series estimation can be used effectively with the historical decennial census microdata samples and should be applied in research analyses that have the potential for substantial clustering effects.

This study sought to identify the magnitude of HIV risk in a diverse sample of Men who use the Internet to seek Sex with Men (MISM), and test if specific subpopulations are at sufficiently increased risk to warrant tailored interventions. A sample of 2,716 American MISM, stratified by race/ethnicity, completed an Internet survey of online and offline sex seeking behavior during the last 3 months. Across most demographics, a minority of MISM reported unprotected anal intercourse with male partners (UAIMP). Across all demographics, risk of UAIMP substantially increased with partners met online. Other predictors of increased online partner risk include being 30–39 years old, having children, not living in the Northeast, and low income. HIV-positive men and African Americans reported increased online and offline partner risk. To address higher risk of UAIMP, online HIV interventions should prioritize the needs of MISM, especially HIV-positive men, with content focused on online-mediated liaisons. [ABSTRACT FROM AUTHOR]

As part of a study to develop effective Internet-based HIV prevention interventions for Men who use the Internet to seek Sex with Men (MISM), we sought information from the target population on; (a) acceptability of sexually explicit media; (b) interest in specific content areas; and (c) identification of credible sources of information. A cross-sectional stratified Internet-based survey design was employed. Between September and November 2005, we recruited 2,716 MISM through Gay.com stratified across race/ethnicity to ensure adequate racial/ethnic diversity. Sixteen Likert-type items assessed acceptability of sexual explicitness, 24 items identified topics for inclusion, and two assessed sources of information. There was near universal acceptability for highly sexually explicit education. Over 75% reported high interest in 10 sexual health topics. HIV positive MISM and MISM engaged in unprotected anal sex with multiple male partners reported significantly less interest in HIV prevention specific content. Differences across age, race/ethnicity and education were identified. Idiosyncratic searches and gay sites were frequently cited sources of information; however blogs, government, and media sites were not. It is acceptable for web-based HIV prevention for MISM to be highly sexually explicit and to provide detailed content relevant to men’s sexual health. Since demographic differences in acceptability and content were minor, it is appropriate for interventions to target across demographics. Interventions to re-engage men engaging in high risk and HIV + MISM should be considered. Leading health agencies should review whether their web information is retrievable, credible and useful to those most at risk. [ABSTRACT FROM AUTHOR]

To assess youth's ability to purchase alcohol in a city previously not assessed—Chicago, Illinois—we hired individuals aged 21 and older who appeared to be aged 18-20 (i.e., pseudo-underage buyers) to make alcohol purchase attempts without age identification in off-premise licensed alcohol establishments. We conducted two purchase attempts at each establishment across 44 community areas, resulting in a total of 652 purchase attempts. Our dependent variable was purchase attempt outcome (purchase, no purchase) and we used four categories of independent variables: characteristics of sellers, establishments, purchase attempts, and community areas. We analyzed our data using a logistic regression model, with purchase attempt outcome regressed on the independent variables. The overall purchase rate was 35.1%, ranging from 0% to 72% across community areas. Buyers were less likely to purchase alcohol in community areas that had populations with higher percentages of Hispanics (OR = 0.99; CI = 0.98, 1.0), and more likely to purchase alcohol in establishments that had more expensive beer (OR = 2.0; CI = 1.50, 2.67) and in areas with higher percentages of unemployed individuals (OR = 1.1; CI = 1.07, 1.14). Although progress has been made since the early 1990s in reducing sales to underage youth, youth still have relatively easy access to alcohol from licensed establishments. We recommend increased use of compliance checks—underage youth attempt to purchase alcohol under the supervision of enforcement agents; if alcohol is sold, the server/seller and/or license holder are penalized-which scientific studies have shown to be the most effective strategy in reducing sales to minors.

As part of a larger study, we investigated the feasibility of using Internet research to capture the demographic characteristics of a largely closeted sexual minority and to report such characteristics in the first national study of transgender persons ever attempted in the United States. To achieve a nonclinical national sample, online convenience sampling was used. Of 1,373 surveys received, 1,229 (90%) were deemed complete and from unique individuals self-identifying as transgender, 18 years or older, and U.S. residents. Participation approximated that predicted by the U.S. Census (2000). Comparison with census data identified the sample as younger, White (non-Hispanic), single, more educated but with less household income, living in smaller towns to medium-sized cities, and less affiliated with traditional Christian denominations. Demographic characteristics differed significantly by both gender and transgender status. The challenge of achieving demographically representative sampling online, as well as implications for future research and policy, are discussed. [ABSTRACT FROM AUTHOR]
