- OBJECTIVE: Factors contributing to the limited use of confidential inquiries into maternal deaths include the negative focus and demotivating effect of such inquiries, perceptions of unavailability of sufficient documentation of events, and lack of time and resources. To ascertain whether these problems can be overcome, variations to confidential inquiries into maternal deaths were introduced in Ghana and Indonesia. METHODS: Clinical review panels were set up as part of the usual process of confidential inquiries, and modifications to the confidential inquiries were introduced. In Ghana, the traditional confidential inquiry process focusing on health facility care was modified to introduce the assessment of positive factors. In addition to the assessment of positive factors, adaptations in Indonesia consisted of including cases of obstetric complications, as well as deaths, and the use of interview testimonials as data sources. Information about resource and time needs for conducting confidential inquiries was collected. RESULTS: The introduction of positive aspects to the process provided a balanced and more motivating setting for the inquiry. The data obtained from case notes in district hospitals and interview testimonials provided sufficient information to assess why maternal deaths and severe complications occurred. The costs of conducting the inquiries ranged from US $4000 to US $11000 (per study), and the estimated time required for a panel member to review each case was more than 3 hours. CONCLUSION: This study introduced practical ways to encourage the implementation of maternal death reviews, inquiries, and audits that are context specific and, therefore, acceptable to local practitioners.

- Type 1 diabetes (T1D) results from autoimmune destruction of β cells. Insufficient availability of biomarkers represents a significant gap in understanding the disease cause and progression. We conduct blinded, two-phase case-control plasma proteomics on the TEDDY study to identify biomarkers predictive of T1D development. Untargeted proteomics of 2,252 samples from 184 individuals identify 376 regulated proteins, showing alteration of complement, inflammatory signaling, and metabolic proteins even prior to autoimmunity onset. Extracellular matrix and antigen presentation proteins are differentially regulated in individuals who progress to T1D vs. those that remain in autoimmunity. Targeted proteomics measurements of 167 proteins in 6,426 samples from 990 individuals validate 83 biomarkers. A machine learning analysis predicts if individuals would remain in autoimmunity or develop T1D 6 months before autoantibody appearance, with areas under receiver operating characteristic curves of 0.871 and 0.918, respectively. Our study identifies and validates biomarkers, highlighting pathways affected during T1D development.
