The realization that the observed kinetic coefficient (kobs ) varies with time in most real-time adsorption system, as against the constant value conceived in the most widely-applied adsorption kinetic models, have attracted much attention in recent time. Understanding the factors that control the extent/degree of time dependency (otherwise known as fractal-like kinetics), is therefore central in taking manipulative advantage of this phenomenon in critical adsorption applications. This study therefore deployed non-fractal-like and fractal-like kinetic approach to study the adsorption of tetracycline on monodispersed starch-stabilized magnetite nanocomposite (MSM)...

OBJECTIVE: We explored the factors associated with disclosure of men who have with sex with men (MSM) behaviors and HIV-positive status among HIV-positive MSM in Nanjing, China. METHODS: Social network analysis and epidemiological methods were combined in this pilot study. Information about participants' (egos') characteristics and behaviors and their social network members (alters) were collected through interview-administered questionnaires. General estimating equation logistic regression analysis was applied in both univariate and multivariate analysis...

Until recently, HIV in Africa was presumed to be driven by poverty, gender inequality and poor governance. The last decade has seen a shift in global and national public health discourses, especially in eastern Africa where new statistical evidence is used to justify prevention efforts to target Key Populations, i.e. men who have sex with men (MSM), injecting drug users, and sex workers. In this article, we focus on Kenya to examine state, NGO and community HIV treatment and prevention efforts targeting MSM, specifically male sex workers...

Achieving optimal health among people living with HIV (PLWH) requires linkage to clinical care upon diagnosis, followed by ongoing engagement in HIV clinical care. A disproportionate number of black/African American and Hispanic/Latino men who have sex with men (MSM) living with HIV do not, however, achieve ongoing care. We conducted semistructured interviews in 2014 with 84 urban black/African American and Hispanic/Latino MSM living with HIV to understand their barriers and facilitators to engagement. We classified men as care-engaged or not at the time of the interview, and conducted content analysis of the interview transcripts to identify barriers and facilitators to engagement...

Background and aimsLate HIV diagnosis is associated with onward HIV transmission, higher morbidity, mortality and healthcare costs. In Italy, more than half of people living with HIV were diagnosed late during the last decade, with a CD4 count < 350 cells/mm3 at diagnosis. We aimed to determine the number and characteristics of people living with undiagnosed HIV infection and low CD4 counts in Italy. Methods: Data on newly reported HIV diagnoses from 2012 -2014 were obtained from the national HIV surveillance system...

Gender identity plays a potentially important role contributing to HIV risk among MSM in South Africa. Where studies have included a focus on gender identity, MSM reporting gender non-conformity have been found to have a higher risk of being HIV positive than other MSM. This article examines HIV risk among gender non-conforming MSM in a sample of 316 MSM in Cape Town, South Africa. Reporting gender non-conformity was associated with higher HIV prevalence and increased HIV risk behaviour. Gender non-conformity was also associated with a higher likelihood of being unemployed and reporting low household incomes...

We describe the first case of lymphogranuloma venereum (LGV) in Poland, with inguino-femoral lymphadenopathy, diagnosed and successfully treated according to the 2013 European LGV guideline. Chlamydia trachomatis genovar L2b, mainly responsible for the ongoing LGV epidemics among men who have sex with men (MSM) in Western European countries, was confirmed. The case also verified that co-infections with other sexually transmitted infections (syphilis and hepatitis C virus) are frequent in MSM LGV patients, as well as the very large difficulties with contact tracing for these patients...

BACKGROUND: Front-line staff at blood collection organizations (BCOs) play important roles in keeping the blood supply safe, yet research on their professional practice and perspectives on training needs is sparse. This qualitative study explored these topics with regard to the then-impending change in donor eligibility for men reporting sex with another man (MSM). STUDY DESIGN AND METHODS: Semistructured, individual interviews with BCO staff (n = 13) in Northern California covered experiences of and opinions on indefinite deferral, the revised 1-year deferral, and anticipated potential challenges arising from the new policy...

BACKGROUND: Whether there is a causal association between digoxin and mortality among patients with atrial fibrillation (AF), with or without congestive heart failure (HF), has been controversial; in particular, two prior analyses of data from the Atrial Fibrillation Follow-up Investigation of Rhythm Management (AFFIRM) trial have yielded conflicting results. We sought to investigate how digoxin impacts mortality, in the full AFFIRM cohort and for various subgroups, by applying marginal structural modeling (MSM) to AFFIRM data...

OBJECTIVES: A measure used for assessing the effectiveness of HIV care and comparing clinical centres is the proportion of people starting antiretroviral therapy (ART) with viral suppression (VS) after 1 year. We propose a method that adjusts for patients' demographic characteristics, and visually compares this measure between different sites accounting for centre size. METHODS: We analysed viral load measurements for UK Collaborative HIV Cohort (UK CHIC) patients starting ART between 2006 and 2013...

BACKGROUND: Treatment-resistant depression (TRD) is a serious and relatively common clinical condition. Lack of consensus on defining and staging TRD remains one of the main barriers to understanding TRD and approaches to intervention. The Maudsley Staging Method (MSM) is the first multidimensional model developed to define and stage treatment-resistance in "unipolar depression". The model is being used increasingly in treatment and epidemiological studies of TRD and has the potential to support consensus...

To understand whether people attending sexual health (SH) clinics are willing to participate in a brief behavioural change intervention (BBCI) to reduce the likelihood of future sexually transmitted infections (STIs) and to understand their preferences for different service designs, we conducted a discrete choice experiment (DCE) with young heterosexual adults (aged 16-25 years), and men who have sex with men (MSM) aged 16 or above, attending SH clinics in England. Data from 368 participants showed that people particularly valued BBCIs that involved talking (OR 1...

Pre-exposure prophylaxis (PrEP) with oral Truvada (tenofovir plus emtricitabine) is effective at preventing HIV infection in high-risk homosexual men. In the United States, PrEP was approved in 2012 and is reimbursed by Medicaid and the majority of private insurers. The situation is diverse and not uniform in the European Union, being PrEP more widely used in France than in the rest of countries. Concerns have been raised that PrEP use may be accompanied by the phenomena of risk compensation or behavioral disinhibition, whereby PrEP users' perception of decreased risk of HIV acquisition may lead them to engage in overall riskier sexual practices and increase their chances of acquiring sexually transmitted infections (STIs) (Blumenthal, et al...

BACKGROUND: Men who have sex with men (MSM) are at increased risk for anal cancer. In cervical cancer screening, patterns of repeated cytology results are used to identify low- and high-risk women, but little is known about these patterns for anal cytology among MSM. METHODS: We analyzed Multicenter AIDS Cohort Study (MACS) data for MSM who were offered anal cytology testing annually (HIV-positive) or every 2 years (HIV-negative) for 4 years. RESULTS: Following an initial negative (normal) cytology, the frequency of a second negative cytology was lower among HIV-positive MSM with CD4≥500 (74%) or CD4<500 (68%) than HIV-negative MSM (83%) (p<0...

Rates of HIV/STI transmission among Black men who have sex with men (BMSM) are alarmingly high and demand urgent public health attention. Stigma related concerns are a key barrier to accessing health care and prevention tools, yet limited research has been focused in this area. Experiences of stigma related to health care were evaluated among 151 BMSM residing in the Atlanta, GA area, both prior to and post HIV or STI diagnosis in a longitudinal study (data collected from 2014 to 2016). Findings demonstrated that inadequate health care engagement is associated with post-diagnosis anticipated stigma (b = - 0...

OBJECTIVE: To evaluate the acceptability and effectiveness of a pilot intervention programme using gay geosocial mobile applications (apps) to offer rapid HIV and other STI tests to men who have sex with men (MSM) in Barcelona between December 2015 and March 2016. METHODOLOGY: We offered rapid HIV, syphilis and hepatitis C testing by sending private messages on apps for sexual and social encounters. Acceptance was defined as the proportion of users who favourably responded to the message and effectiveness was defined as the proportion of users who attended our facilities among those who were interested in attending...

BACKGROUND: Sexualised drug use (SDU) refers to the use of drugs in a sexual context. This includes 'Chemsex'- the use of drugs (specifically crystal methamphetamine, GHB/GBL and mephedrone) before or during planned sexual activity to sustain, enhance, disinhibit or facilitate the experience. Here we aimed to synthesise available UK prevalence data for Chemsex, SDU and the use of Chemsex drugs in an undefined context (CDU) in men who have sex with men (MSM). METHODS: Papers published between January 2007 and August 2017 reporting Chemsex, SDU and/or Chemsex drug use (CDU) prevalence in MSM were identified through PubMed...

INTRODUCTION: HIV-1 dual infection is a condition that results from infection with at least two HIV-1 variants from different sources. The scarceness of information on this condition is partly due to the fact that its detection is technically challenging. Using next-generation sequencing we defined the extent of HIV-1 dual infection in a cohort of men who have sex with men (MSM). MATERIAL & METHODS: Eighty-six MSM, diagnosed with HIV-1 subtype B infection between 2008 and 2013 were selected for next-generation sequencing of the HIV-1 envelope V3...
