Objective of this study was to describe the patient characteristics and clinical presentation of laboratory confirmed lymphogranuloma venereum (LGV) cases, diagnosed at the Institute of Tropical Medicine (ITM), Antwerp, Belgium. Demographic and biomedical characteristics of all patients with chlamydia-positive sample results were retrieved for the years 2013 and 2014. Samples were obtained from both symptomatic and asymptomatic patients who consulted at the HIV/STI clinic. Fifty four patients with laboratory confirmed LGV were detected among 3885 nucleic acid amplification tests (NAATs) performed for the detection of chlamydia during the two years under review...

Genome-wide association studies (GWAS) have proven highly successful in identifying single nucleotide polymorphisms (SNPs) associated with breast cancer (BC) risk. The majority of these studies are on European populations, with limited SNP association data in other populations. We genotyped 51 GWAS-identified SNPs in two independent cohorts of Singaporean Chinese. Cohort 1 comprised 1294 BC cases and 885 controls and was used to determine odds ratios (ORs); Cohort 2 had 301 BC cases and 243 controls for deriving polygenic risk scores (PRS)...

Background: Familial Mediterranean fever (FMF) is a hereditary autoinflammatory disease characterized by recurrent fever attacks and serositis. Nonspecific manifestations of the FMF can mimic many common acquired disorders such as infections and acute abdomen. This can delay recognition for many years and lead to comprehensive assessments and even unnecessary surgeries. Untreated FMF may lead to serious complications such as end-stage renal disease and malabsorption due to amyloid deposits in the kidneys and the digestive system...

PURPOSE: Small cell carcinoma of the prostate (SCCP) is an aggressive disease that can arise de novo or by transdifferentiation from prostate adenocarcinoma. Alterations in anaplastic lymphoma kinase (ALK) gene are involved in neuroblastoma, lung cancer, and other malignancies but its role in SCCP has not been documented. We describe a patient with refractory de novo SCCP with ALK F1174C activating mutation who obtained clinical benefit from treatment with ALK inhibitor. EXPERIMENTAL DESIGN: Next-generation sequencing (NGS) was used to analyze primary and circulating tumor DNA (ctDNA)...

The chloroquinoline scaffold is characteristic of anti-malarial drugs such as chloroquine (CQ) or amodiaquine (AQ). These drugs are also described for their potential effectiveness against prion disease, HCV, EBV, Ebola virus, cancer, Parkinson or Alzheimer diseases. Amyloid precursor protein (APP) metabolism is deregulated in Alzheimer's disease. Indeed, CQ modifies amyloid precursor protein (APP) metabolism by precluding the release of amyloid-beta peptides (Aβ), which accumulate in the brain of Alzheimer patients to form the so-called amyloid plaques...

Chemsex is the colloquial term used for a specific pattern of drug use that is increasingly common among men who have sex with men (MSM) globally. The recreational substances employed are used specifically in a sexualized context. The reasons for chemsex among MSM are complex. The Anova Health Institute (Anova) provided harm-reduction services in Cape Town, South Africa in 2013 and 2014. This project, known as Tikking the Boxes had two objectives: first to provide direct harm-reduction services to drug-using MSM in Cape Town, South Africa, and second, to reduce HIV and hepatitis B and C transmission among this population...

Previous research indicates that gay and bisexual men (GBM) have significantly more sexual partners than same-aged heterosexual men and women. As a result, some HIV intervention programs have focused on partner reduction. However, new research findings question the relevance of sexual partner number as a sexual risk measure for GBM given Treatment as Prevention (TasP) programs and new seroadaptive strategies which have led to lower GBM community viral load and new HIV prevention behaviors. To assess if sexual partner number continues to remain an important measure of sexual risk for GBM living in a city that actively promotes TasP as provincial policy, we analysed cross-sectional data from 719 GBM recruited through respondent-driven sampling in Vancouver, Canada...

Lesbian, gay, bisexual, transgender and queer/questioning (LGBTQ+) young people of colour are exposed to intersecting dynamics of social prejudice and discrimination related to sexuality and gender as well as race/ethnicity. In particular, Latinx-identifying LGBTQ+ young people face unique challenges in their lives, due to cultural stressors that stigmatise expansive gender and sexual identities. While it is crucial to examine the effects of multiple stressors on the well-being of LGBTQ+ young people of colour, this risk-based focus can overshadow the resilient capacities of multiply marginalised groups...

We examined social determinants of health associated with all-cause mortality among 602 people living with HIV/AIDS in Ontario, Canada. Mortality status was verified at 1-, 3-, and 5-year follow-up visits with information obtained from proxies (family members, partners, and friends), obituaries, and local AIDS memorial lists. Of the 454 people for whom mortality information was available, 53 individuals died yielding a crude mortality rate of 22.3 deaths per 1000 person-years, a rate substantially higher than the rate in the general population (6...

The Young Men's Health Project (YMHP) has shown efficacy in reducing drug use and condomless anal sex (CAS) with casual partners among young gay, bisexual and other men who have sex with men (YGBMSM). The study examined whether relationship status at the time of intervention predicted response to YMHP by comparing baseline (pre-intervention) and follow-up (3, 6, 9, and 12 months post-intervention) data from the original trial. A group of 13 partnered YGBMSM who received YMHP was compared to a matched subsample of single YGBMSM...

Many epithelial stem cell populations follow a pattern of stochastic stem cell divisions called 'neutral drift'. It is hypothesised that neutral competition between stem cells protects against the acquisition of deleterious mutations. Here we use a Porcupine inhibitor to reduce Wnt secretion at a dose where intestinal homoeostasis is maintained despite a reduction of Lgr5+ stem cells. Functionally, there is a marked acceleration in monoclonal conversion, so that crypts become rapidly derived from a single stem cell...

BACKGROUND: Computed tomography aortic valve calcium scoring (CT-AVC) holds promise for the assessment of patients with aortic stenosis (AS). We sought to establish the clinical utility of CT-AVC in an international multicenter cohort of patients. METHODS AND RESULTS: Patients with AS who underwent ECG-gated CT-AVC within 3 months of echocardiography were entered into an international, multicenter, observational registry. Optimal CT-AVC thresholds for diagnosing severe AS were determined in patients with concordant echocardiographic assessments, before being used to arbitrate disease severity in those with discordant measurements...

BACKGROUND: Across sub-Saharan Africa (SSA), HIV disproportionately affects men-who-have-sex-with-men (MSM) compared with other men of the same age group in the general population. Access to HIV services remains low among this group although several effective interventions have been documented. It is therefore important to identify what has worked well to increase the reach of HIV services among MSM. METHODS: We searched MEDLINE, POPLINE and the Web of Science databases to collect published articles reporting HIV interventions among MSM across sub-Saharan Africa...

The prediction of metal bioavailability in soils is critical to metal risk assessments and the amount of dissolved metal in soils is a key factor determining bioavailability. Because the recently developed geochemical multi-surface models (MSMs) offer a promising tool for the determination of metal partitioning in soils, in this study, a MSM based on generic parameters was used to assess the bioavailability of Cd in wheat (Triticum aestivum L.) growing in 12 soils with a wide range of properties. The amount of MSM-calculated dissolved Cd correlated strongly with the amount of Cd uptake by wheat (R2 =0...

BACKGROUND: Many mathematical models have investigated the population-level impact of expanding antiretroviral therapy (ART), using different assumptions about HIV disease progression on ART and among ART dropouts. We evaluated the influence of these assumptions on model projections of the number of infections and deaths prevented by expanded ART. METHODS: A new dynamic model of HIV transmission among men who have sex with men (MSM) was developed, which incorporated each of four alternative assumptions about disease progression used in previous models: (A) ART slows disease progression; (B) ART halts disease progression; (C) ART reverses disease progression by increasing CD4 count; (D) ART reverses disease progression, but disease progresses rapidly once treatment is stopped...

'Medicalisation' of same sex relations is a phenomenon that reached its peak in the 1950s and 1960s. The rise of gay liberation produced a divisive political contest with the psychiatric profession and adherents of the orthodox 'medical model' in the United States and - to a lesser extent - in the United Kingdom. This socio-historical process occurred throughout the English-speaking world, but much less is known about its dynamics in smaller countries such as New Zealand where the historiography on this issue is very sparse...

It is critical to ensure that long-term care (LTC) homes are sensitive to the needs of lesbian, gay, bisexual, and transgender (LGBT) older adults. However, the extent to which the LTC home sector has adopted recommended strategies is unknown. This qualitative study reports findings from two initiatives: Semi-structured telephone interviews with Canadian LTC home administrators on strategies adopted to support LGBT inclusivity (n = 32), and discussions with participants attending a 2-day meeting on supporting LGBT inclusivity in LTC (n = 25)...

On December 11, 2013, the Indian Supreme Court recriminalized non-peno-vaginal sex under Sec. 377 of the Indian Penal Code (IPC), overturning a 2009 ruling that deemed IPC Sec. 377 unconstitutional. Similar "sodomy laws" in other countries have been associated with increased violence, harassment, and other discrimination against men who have sex with men (MSM) and transgender women. However, few studies have looked at the effects of such a law in an Indian context. This study examined experiences of victimization among MSM and hijra/transgender women (MSM-H) in the State of Maharashtra using a mixed-method approach...
