Purpose: Pregnant and postpartum mothers with physical disabilities face discrimination in healthcare settings and high rates of maternal and obstetric complications, as well as having higher rates of lifetime depression prior to pregnancy, potentially increasing their likelihood of experiencing postpartum depression (PPD). Some studies have found higher rates of PPD in mothers with physical disabilities than in mothers without physical disabilities, with more disabling symptoms associated with worse PPD systems; however, the literature is sparse and heterogenous. This systematic review and meta-analysis advanced this area of study by evaluating the strength of the association between PPD and physical disability.

Fast and interpretable mortality risk scores for critical care patients.

J Am Med Inform Assoc

January 2025

Department of Computer Science, Duke University, Durham, NC 27708, United States.

Objective: Prediction of mortality in intensive care unit (ICU) patients typically relies on black box models (that are unacceptable for use in hospitals) or hand-tuned interpretable models (that might lead to the loss in performance). We aim to bridge the gap between these 2 categories by building on modern interpretable machine learning (ML) techniques to design interpretable mortality risk scores that are as accurate as black boxes.

Material And Methods: We developed a new algorithm, GroupFasterRisk, which has several important benefits: it uses both hard and soft direct sparsity regularization, it incorporates group sparsity to allow more cohesive models, it allows for monotonicity constraint to include domain knowledge, and it produces many equally good models, which allows domain experts to choose among them.
