Objectives: Home health care (HHC) serves more than 5 million older adults annually in the United States, aiming to prevent unnecessary hospitalizations and emergency department (ED) visits. Despite efforts, up to 25% of patients in HHC experience these adverse events. The underutilization of clinical notes, aggregated data approaches, and potential demographic biases have limited previous HHC risk prediction models.

Introduction: Little is known about the range and frequency of symptoms among older adult home healthcare patients with urinary incontinence, as this information is predominantly contained in clinical notes. Natural language processing can uncover symptom information among older adults with urinary incontinence to promote holistic, equitable care.

Design: We conducted a secondary analysis of cross-sectional data collected between January 1, 2015, and December 31, 2017, from the largest HHC agency in the Northeastern United States.

Article Synopsis
  • The study examines how stigma and bias related to race and other minoritized statuses affect pregnancy and birth outcomes by analyzing stigmatizing language in electronic health records.
  • Researchers developed automated natural language processing (NLP) methods to identify two types of stigmatizing language in labor and birth notes: marginalizing language and power/privilege language.
  • The results showed that Decision Trees were most effective for marginalizing language with an F-score of 0.73, while Support Vector Machines excelled in identifying power/privilege language with an F-score of 0.91, marking a significant advancement in using NLP to detect bias in medical documentation.

Article Synopsis
  • The study analyzed 1,117 birth admission electronic health record (EHR) notes from two urban hospitals to identify stigmatizing language used in clinical documentation for pregnant individuals during their labor and delivery.
  • It categorized stigmatizing language into disapproval (39.3%), questioning patient credibility (37.7%), and other forms, with a new category highlighting power/privilege biases noted in 3.3% of the records.
  • The findings revealed that such language often undermined the credibility and decision-making abilities of birthing people, suggesting a need for targeted interventions to enhance perinatal outcomes for all families.

Recently, we showed that pancreatitis in the context of profound β-cell deficiency was sufficient to induce islet cell transdifferentiation. In some circumstances, this effect was sufficient to result in recovery from severe diabetes. More recently, we showed that the molecular mechanism by which pancreatitis induced β-cell neogenesis by transdifferentiation was activation of an atypical GPCR called Protease-Activated Receptor 2 (PAR2).

The International Pancreas and Islet Transplant Association (IPITA), in conjunction with the Transplantation Society (TTS), convened a workshop to consider the future of pancreas and islet transplantation in the context of potential competing technologies that are under development, including the artificial pancreas, transplantation tolerance, xenotransplantation, encapsulation, stem cell derived beta cells, beta cell proliferation, and endogenous regeneration. Separate workgroups for each topic and then the collective group reviewed the state of the art, hurdles to application, and proposed research agenda for each therapy that would allow widespread application. Herein we present the executive summary of this workshop that focuses on obstacles to application and the research agenda to overcome them; the full length article with detailed background for each topic is published as an online supplement to Transplantation.

Background: Human pancreatic islet structure poses challenges to investigations that require specific modulation of gene expression. Yet dissociation of islets into individual cells destroys cellular interactions important to islet physiology. Approaches that improve transient targeting of gene expression in intact human islets are needed in order to effectively perturb intracellular pathways to achieve biological effects in the most relevant tissue contexts.

Insulin therapy became a reality in 1921 dramatically saving lives of people with diabetes, but not protecting them from long-term complications. Clinically successful free islet implants began in 1989 but require life long immunosuppression. Several encapsulated islet approaches have been ongoing for over 30 years without defining a clinically relevant product.
