Data access arrangements in genomic research consortia.

One of the most common terms that is used to describe entities responsible for sharing genomic data for research purposes is 'genomic research consortium'. However, there is a lack of clarity around the language used by consortia to describe their data sharing arrangements. Calls have been made for more uniform terminology. This article reports on a review of the genomic research consortium literature illustrating a wide diversity in the language that has been used over time to describe the access arrangements of these entities. The second component of this research involved an examination of publicly available information from a dataset of 98 consortia. This analysis further illustrates the wide diversity in the access arrangements adopted by genomic research consortia. A total of 12 different access arrangements were identified, including four simple forms (open, consortium, managed and registered access) and eight more complex tiered forms (for example, a combination of consortium, managed and open access). The majority of consortia utilised some form of tiered access, often following the policy requirements of funders like the US National Institutes of Health and the UK Wellcome Trust. It was not always easy to precisely identify the access arrangements of individual consortia. Greater consistency, clarity and transparency is likely to be of benefit to donors, depositors and accessors alike. More work needs to be done to achieve this end.

Per- and polyfluoroalkyl substances exposure is associated with polycystic ovary syndrome risk among women attending a fertility clinic.

Previous studies reported that exposures to per- and polyfluoroalkyl substances (PFAS), largely in higher exposed populations, were associated with elevated risk of polycystic ovary syndrome (PCOS). However, studies evaluating PCOS risk in populations with lower background exposures to PFAS are limited. This study aimed to examine the associations between serum PFAS concentrations and PCOS risk among women attending a U.S. academic fertility clinic during 2005-2019. A total of 502 females who sought fertility evaluation and assisted reproduction treatments were included. Nine PFAS were quantified in non-fasting serum samples collected at study entry. Diagnosis of PCOS was based on the Rotterdam criteria. We used logistic regression to examine the odds ratio (OR) of PCOS in relation to individual PFAS concentrations (continuous and by tertiles) and quantile g-computation (QGC) and Bayesian Kernel Machine Regression (BKMR) to examine the joint associations of PFAS mixture with PCOS. Most participants were White and had a graduate degree or higher. Per doubling of serum perfluorooctane sulfonate (PFOS) and perfluorohexane sulfonate (PFHxS) concentrations were associated with higher odds of PCOS [OR (95%CI): 1.70 (1.06, 2.81) and 1.45 (1.02, 2.08) for PFOS and PFHxS respectively]. There was a dose-response relationship of PFOS with PCOS risk (p of trend by PFOS tertiles = 0.07). Both QGC and BKMR identified PFOS as the most important contributor among the mixture to PCOS risk. No clear joint effects were found for other PFAS or PFAS mixtures on PCOS risk. Our findings are consistent with existing evidence in populations with higher background PFAS concentrations and highlight the adverse effects of PFAS exposure on reproductive health. Findings can inform public health measures and clinical care to protect populations vulnerable to PCOS, in part, due to environmental exposures.

What Domains of Belgian Euthanasia Practice are Governed and by Which Sources of Regulation: A Scoping Review.

BACKGROUND: Multiple sources of regulation seek to shape euthanasia practice in Belgium, including legislation and training. This study comprehensively mapped which of these sources govern which domains of euthanasia practice, such health professionals' obligations, or managing patient requests. METHOD: Scoping review methodology was used to search for scholarly records which discussed Belgian euthanasia regulation. Template analysis was used to generate themes describing the domains of euthanasia practice governed by sources of regulation. RESULTS: Of 1364 records screened, 107 records were included. Multiple sources of regulation govern each domain, which are: the permissible scope of euthanasia; the legal status of a euthanasia death; the euthanasia process; the rights, obligations, and roles of those involved; system workings; and support for health professionals who provide euthanasia. CONCLUSIONS: Domains with significant yet fragmented regulation may lead to inconsistent care provision. Policymakers should develop coherent guidance to support health professionals to navigate this regulatory landscape.

Mapping Sources of Assisted Dying Regulation in Belgium: A Scoping Review of the Literature.

Belgium has over 20 years of experience regulating assisted dying (AD). While much research considers this end-of-life practice, no studies have comprehensively analysed the various sources of regulation that govern it, including law, professional standards, and ethics. A scoping review identified all sources of regulation that guide AD practice, and their regulatory functions. Databases and reference lists were searched for records which met inclusion criteria between 11/2/22 and 25/3/22. Existing scholarship was used to identify sources of regulation, and thematically analyse their functions. Of the initial sample of 1364 records, 107 were included. Six sources of regulation were identified: law, policies, professional standards, training, advisory documents, and system design. Three regulatory functions were identified: prescribing conduct, scaffolding to support practice, and monitoring the system. The Belgian AD regulatory framework is multifaceted, complex, and fragmented. Providers must navigate and reconcile numerous sources of guidance providing this form of end-of-life care.
