Abstract

ObjectiveAdvances in metabolomics now allow high-throughput biomarker profiling of large population studies. We aimed to identify circulating metabolic biomarkers predictive of type 2 diabetes in young adults.\n\nMethodsNuclear magnetic resonance metabolomics was used to quantify 229 metabolic measures in 11,896 individuals from four Finnish cohorts (mean age 33 years, range 24-45). Associations between baseline metabolites and risk of type 2 diabetes onset during 8-15 years of follow-up (392 incident cases) were assessed by logistic regression adjusted for sex, age, body mass index, and fasting glucose.\n\nResultsOut of 229 metabolic measures, 113 were associated with incident diabetes in meta-analysis of the four cohorts (P<0.0009; odds ratios per 1-SD: 0.59-1.50). Among the strongest predictors of diabetes risk were branched-chained and aromatic amino acids (odds ratios 1.31-1.33), triglyceride fractions within the largest very-low-density lipoprotein particles (VLDL; odds ratios 1.33-1.50)), as well as linoleic omega-6 fatty acids (odds ratio 0.75) and free cholesterol in large high-density lipoprotein particles (HDL; odds ratio 0.59). A biomarker score comprised of phenylalanine, free cholesterol in large HDL, and the ratio of cholesteryl esters to total lipids in large VLDL was predictive of the risk for future diabetes in an independent validation cohort (odds ratio 10.1 [95% confidence intervals 4.2-24.1] comparing individuals in upper vs lower fifth of biomarker score). Adjustment for routine lipids and insulin attenuated the odds ratio to 5.8 [2.2-15.1].\n\nConclusionsMetabolic aberrations across multiple molecular pathways are predictive of the long-term risk of type 2 diabetes in young adults. Comprehensive metabolic profiling may potentially help targeting preventive interventions for young asymptomatic individuals at increased risk for type 2 diabetes.

Male clients of male sex workers in West Africa: A neglected high risk population

Research on male clients of male sex workers (MCMSW) has been neglected for a long time globally. We aimed to characterize MCMSW and to identify factors associated with their sexual practices using data from the prospective cohort study CohMSM conducted in Burkina Faso, Cote dIvoire, Mali and Togo. Our study focused on HIV-negative men who have sex with other men (MSM) recruited between 06/2015 and 01/2018 by a team of trained peer educators. Scheduled study visits at 6, 12 and 18 months included medical examinations, HIV screening, risk-reduction counselling and face-to-face interviews to collect information on their sociodemographic characteristics, sexual behaviours, and HIV risk-reduction strategies (HIV-RRS). Three stigmatization sub-scores were constructed (experienced, perceived and internalized). Mixed-effects logistic regression was used for data analysis. Of the 280 participants recruited at baseline, 238, 211 and 118, respectively, had a follow-up visit at 6, 12 and 18 months. Over a total of 847 visits, 47 transactional sex (TS) encounters were reported by 38 MCMSW (13.6%). Of the latter, only one participant reported systematic TS (2.6%), 18 (47.4 %) stopped reporting TS after baseline, and 6 (15.8%) reported TS after baseline. Thirteen participants (34.2 %) reported occasional TS. After adjusting for country of study and age, the following self-reported factors were associated with a greater likelihood of being MCMSW: protected anal sex, exclusively insertive anal sex with male sexual partners, avoidance of sex after consuming psychoactive products and experiencing stigmatization (all during the previous 6 months). The majority of MCMSW in this study employed HIV-RRS with male sexual partners, including engaging in protected anal sex, avoidance of sex when consuming psychoactive products, and practising exclusively insertive anal sex.

Cases of Cutaneous Leishmaniasis in a peri-urban settlement in Kenya, 2016

BackgroundCutaneous Leishmaniasis is a neglected tropical disease caused by a protozoan and transmitted by sand-fly bite. Following reports of a possible outbreak of cutaneous leishmaniasis in 2016, we conducted a review of hospital records and a follow up case control study to determine the magnitude of the disease, characterize the cases and identify factors associated with the disease in Gilgil, a peri-urban settlement in Central Kenya. MethodsWe reviewed hospital records, conducted active case search in the community and carried out a case-control study. Medical officers in the study team made clinical diagnosis of cutaneous leishmaniasis cases based on presence of a typical skin ulcer. We enrolled 58 cases matched by age and residence to 116 controls in a case control study. We administered structured questionnaires and recorded environmental observations around homes of cases and controls. Simple proportions, means and medians were calculated for categorical data and continuous data respectively. Logistic regression models were constructed for individual, indoor and outdoor factors associated with the outbreak. ResultsWe identified 255 suspected cases and one death; Females constituted 56% (142/255), median age of the cases was 7 years (IQR 14). Cases were clustered around Gitare (28.6%, 73/255) and Kambi-Turkana (14%, 36/255) with seasonal peaks between June-November. Among individual factors, staying outside the residence in the evening after sunset (OR 4.1, CI 1.2-16.2) and occupation involving visiting forests (OR 4.56, CI 2.04-10.22) had significant associations with disease. Sharing residence with a cutaneous leishmaniasis patient (OR 14.4, CI 3.8-79.3), a house with alternative roofing materials (OR 7.9, CI 1.9-45.7) and residing in a house with cracked walls (OR 2.3, CI 1.0-4.9) were significant among indoor factors while sighting rock hyraxes near residence (OR 5.3, CI 2.2-12.7), residing near a forest (OR 7.8, CI 2.8-26.4) and living close to a neighbour with cutaneous leishmaniasis (OR 6.8, CI 2.8-16.0) had increased likelihood of disease. Having a cultivated crop farm surrounding the residence (OR 0.1, CI 0.0-0.4) was protective. Conclusions/SignificanceThis study reveals the large burden of cutaneous leishmaniasis in Gilgil. There is strong evidence for both indoor and outdoor patterns of disease transmission. Occupations and activities that involve visiting forests or residing near forests and sharing a house or neighbourhood with a person with CL were identified as significant exposures of the disease. The role of environmental factors and wild mammals in disease transmission should be investigated further Author summaryLeishmaniasis is a group of diseases caused by a protozoa (Leishmania) and affects humans and other mammals following the bite of an infected sand-fly. Cutaneous form of the disease (cutaneous leishmaniasis) is considered a neglected tropical disease mainly affecting the poor destabilized or migrant populations in rural areas. Recently, the disease has expanded its geographical range and invaded previously non-endemic areas including areas surrounding large urban centres that are experiencing human population influx leading to multiple localised disease outbreaks. In this paper, we report findings of a study we conducted to determine the burden and factors promoting the spread of cutaneous leishmaniasis in a peri-urban settlement in Kenya. Our results indicate a high burden of cutaneous leishmaniasis in this area and an association of the disease with several groups of factors at individual, indoor and outdoor environments. Many cases of cutaneous leishmaniasis were linked to activities that involved visiting the forested areas around homes, underpinning the significance of human activity in forests in these areas in spread of the disease.

A cross-sectional study to assess the magnitude of Hypertension and Type 2 Diabetes Mellitus in Hatcliffe, Harare

BackgroundHypertension (HTN) and type 2 diabetes mellitus (T2DM) are reported to be on the increase in developing countries. In this study we investigated the epidemiology of the prevalence of HTN and T2DM and its correlates in a high density area. We carried out this study to assess the magnitude of the prevalence of HTN and T2DM so that we can query the drivers that are causing an increase conditions in these conditions. MethodsWe conducted a cross-sectional study in Hatcliffe, a high density area (HDA) in Harare. We interviewed, bled, took anthropometric and measured blood pressure of 381 participants. We investigated HbA1c, blood pressure, BMI and prevalence of prehypertension, prediabetes, co-existence of HTN and T2DM. A geospatial analysis was carried out to ascertain distribution patterns of HTN and T2DM in Hatcliffe. ResultsThe prevalence for prehypertension and prediabetes is higher than it is for full blown conditions of the HTN and T2DM. The prevalence of prehypertension was 35.4% and prediabetes was 29%. The prevalence of HTN in this study was 14.4% whilst that of T2DM was 3.93%. Out of the 55 participants that had developed HTN five had developed T2DM. There was no significant difference in the HTN and T2DM clusters. ConclusionsThe prevalence for prehypertension and prediabetes is higher than it is for full blown conditions of the HTN and T2DM. This indicates the importance of having a strategy for reducing the number of prediabetes and prehypertensive cases so that cases of full blown T2DM and HTN remain low.
