Designing comprehensible healthcare public reports: An investigation of the use of narratives and tests of quality metrics to support healthcare public report sensemaking.

Appl Ergon 2021 May 3;95:103452. Epub 2021 May 3.

Department of Industrial Engineering, Clemson University, 110 Freeman Hall, Clemson, SC, 29634, USA.

A key challenge for designers of healthcare public reports is the development of a presentation format that accurately communicates the variability in the quality of care among healthcare systems. This study conducted in the United States explored whether presenting public report information within narratives and with tests of healthcare quality metrics supported the public report sensemaking process. The study involved 200 participants and employed a 2 (public report information presented in the standard format, presented within a narrative) * 2 (no tests of quality metrics added to standard report, metrics tests added) between-subjects experimental design.

Maximizing success in single-session EUS-directed transgastric ERCP: a retrospective cohort study to identify predictive factors of stent migration.

Gastrointest Endosc 2021 May 3. Epub 2021 May 3.

Thomas Jefferson University Hospital, Philadelphia, PA.

Background And Aims: EUS-directed transgastric ERCP (the EDGE procedure) is a simplified method of performing ERCP in Roux-en-Y gastric bypass patients. [1] The EDGE procedure involves placement of a lumen-apposing metal stent (LAMS) into the excluded stomach to serve as a conduit for passage of the duodenoscope for pancreatobiliary intervention. Originally a multistep process, urgent indications for ERCP have led to the development of single-session EDGE (SS-EDGE) with LAMS placement and ERCP performed in the same session. Read More

PLoS One 2021 6;16(5):e0251251. Epub 2021 May 6.

Swiss Tropical and Public Health Institute, Basel, Switzerland.

Previous research has shown that the built environment plays a crucial role for health-related quality of life (HRQoL) and health care utilization. But, there is limited evidence on the independence of this association from lifestyle and social environment. The objective of this cross-sectional study was to investigate these associations, independent of the social environment, physical activity and body mass index (BMI). Read More

Covichem: A biochemical severity risk score of COVID-19 upon hospital admission.

PLoS One 2021 6;16(5):e0250956. Epub 2021 May 6.

Department of Biochemistry, Pellegrin Hospital, University Hospital of Bordeaux, Bordeaux, France.

Clinical and laboratory predictors of COVID-19 severity are now well described and combined to propose mortality or severity scores. However, they all necessitate saturable equipment such as scanners, or procedures difficult to implement such as blood gas measures. To provide an easy and fast COVID-19 severity risk score upon hospital admission, and keeping in mind the above limits, we sought for a scoring system needing limited invasive data such as a simple blood test and co-morbidity assessment by anamnesis.

Tumor-associated Stromal Cellular Density as a Predictor of Recurrence and Mortality in Breast Cancer: Results from Ethnically-diverse Study Populations.

Cancer Epidemiol Biomarkers Prev 2021 May 5. Epub 2021 May 5.

Division of Cancer Epidemiology and Genetics, National Cancer Institute.

Background: Tumor-associated stroma is comprised of fibroblasts, tumor infiltrating lymphocytes (TILs), macrophages, endothelial, and other cells, that interactively influence tumor progression through inflammation and wound repair. Although gene expression signatures reflecting wound repair predict breast cancer survival, it is unclear whether combined density of tumor-associated stromal cells, a morphological proxy for inflammation and wound repair signatures on routine hematoxylin and eosin (H&E)-stained sections, is of prognostic relevance.

Methods: By applying machine learning to digitized H&E-stained sections for 2,084 breast cancer patients from China (n=596; 24-55years), Poland (n=810; 31-75years), and the United States (n=678; 55-78years), we characterized tumor-associated stromal cellular density (SCD) as the percentage of tumor-stroma that is occupied by nucleated cells.

Quantile modeling through multivariate log-normal/independent linear regression models with application to newborn data.

Biom J 2021 May 5. Epub 2021 May 5.

Departamento de Estatística, Universidade de São Paulo, São Paulo, Brazil.

In this article, we propose and study the class of multivariate log-normal/independent distributions and linear regression models based on this class. The class of multivariate log-normal/independent distributions is very attractive for robust statistical modeling because it includes several heavy-tailed distributions suitable for modeling correlated multivariate positive data that are skewed and possibly heavy-tailed. Besides, expectation-maximization (EM)-type algorithms can be easily implemented for maximum likelihood estimation. Read More

Psychometric Evaluation of a Big Five Personality State Scale for Intensive Longitudinal Studies.

Assessment 2021 May 5:10731911211008254. Epub 2021 May 5.

University of Pittsburgh, Pittsburgh, PA, USA.

Despite enthusiasm for using intensive longitudinal designs to measure day-to-day manifestations of personality underlying differences between people, the validity of personality state scales has yet to be established. In this study, we evaluated the psychometrics of 20-item and 10-item daily, Big Five personality state scales in three independent samples ( = 1,041). We used multilevel models to separately examine the validity of the scales for assessing personality variation at the between- and within-person levels. Read More
