Pregnancy and the postpartum period are increasingly recognised as sensitive windows for cardiometabolic disease risk. Growing evidence suggests environmental exposures, including endocrine-disrupting chemicals (EDCs), are associated with an increased risk of pregnancy complications that are associated with long-term cardiometabolic risk. However, the impact of perinatal EDC exposure on subsequent cardiometabolic risk post-pregnancy is less understood. The Environmental Reproductive and Glucose Outcomes (ERGO) Study was established to investigate the associations of environmental exposures during the perinatal period with post-pregnancy parental cardiometabolic health.

Pregnant individuals aged ≥18 years without pre-existing diabetes were recruited at

We enrolled 653 unique pregnancies and retained 633 through delivery. Participants had a mean age of 33 years, 10% (n=61) developed gestational diabetes and 8% (n=50) developed pre-eclampsia. Participant pregnancy and postpartum urinary phthalate metabolite concentrations and postpartum glycaemic biomarkers were quantified. To date, studies within ERGO found higher exposure to phthalates and phthalate mixtures, and separately, higher exposure to radioactive ambient particulate matter, were associated with adverse gestational glycaemic outcomes. Additionally, certain personal care products used in pregnancy, notably hair oils, were associated with higher urinary phthalate metabolite concentrations, earlier gestational age at delivery and lower birth weight.

Future work will leverage the longitudinal data collected on pregnancy and cardiometabolic outcomes, environmental exposures, questionnaires, banked biospecimens and paediatric data within the ERGO Study.

Hip osteoarthritis (OA) is a major cause of pain and disability worldwide. Lack of effective therapies may reflect poor knowledge on its aetiology and risk factors, and result in the management of end-stage hip OA with costly joint replacement. The Worldwide Collaboration on OsteoArthritis prediCtion for the Hip (World COACH) consortium was established to pool and harmonise individual participant data from prospective cohort studies. The consortium aims to better understand determinants and risk factors for the development and progression of hip OA, to optimise and automate methods for (imaging) analysis, and to develop a personalised prediction model for hip OA.

World COACH aimed to include participants of prospective cohort studies with ≥200 participants, that have hip imaging data available from at least 2 time points at least 4 years apart. All individual participant data, including clinical data, imaging (data), biochemical markers, questionnaires and genetic data, were collected and pooled into a single, individual-level database.

World COACH currently consists of 9 cohorts, with 38 021 participants aged 18–80 years at baseline. Overall, 71% of the participants were women and mean baseline age was 65.3±8.6 years. Over 34 000 participants had baseline pelvic radiographs available, and over 22 000 had an additional pelvic radiograph after 8–12 years of follow-up. Even longer radiographic follow-up (15–25 years) is available for over 6000 of these participants.

The World COACH consortium offers unique opportunities for studies on the relationship between determinants/risk factors and the development or progression of hip OA, by using harmonised data on clinical findings, imaging, biomarkers, genetics and lifestyle. This provides a unique opportunity to develop a personalised hip OA risk prediction model and to optimise methods for imaging analysis of the hip.

Tuberculosis (TB) is a main concern of health care workers in sub-Saharan Africa. Healthcare workers have the potential to have contact with TB patients and are the main stakeholders in healthcare settings to implement TB infection control, and the poor practice of TB infection control may increase the risk of transmission of TB in healthcare settings. However, there is no consistent conclusion on the TB infection control practice among healthcare workers in Ethiopia. Thus, this study aimed to determine the pooled magnitude of TB infection control practice and associated factors among healthcare workers in Ethiopia.

This systematic review and meta-analysis will be done by following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. The following databases will be used to search for articles: PubMed, Cochrane Library, Google Scholar and grey literatures. The quality of studies will be assessed using the Joanna Briggs Institute (JBI) critical appraisal checklist. The data from included studies will be extracted using Microsoft Excel V.2016, and the extracted data will be analysed using STATA V.16. Forest plot and I² statistics will be done for heterogeneity. A funnel plot and Egger’s regression test will be conducted to check for publication bias. Potential sources of bias will be identified by subgroup analysis and meta-regression. Any type of study design conducted in Ethiopia and in English language will be included.

Ethics approval is not required, and the findings will be published in peer-reviewed journal.
