Abstract

ObjectiveThe aim of this study was to describe the adult rheumatology workforce in the United States, assess change in rheumatology providers over time, and identify variation in rheumatology practice characteristics.MethodsUsing national Medicare claims data from 2006 to 2020, clinically active rheumatology physicians and advanced practice providers (APPs) were identified. Each calendar year was used for inclusion, exclusion, and analysis, and providers were determined to be entering, exiting, or stable based upon presence or absence in the prior or subsequent years of data. Characteristics (age, gender, practice type, rural, and region) of rheumatologists were determined for 2019 and in mutually exclusive study periods from 2009 to 2011, 2012 to 2015, and 2016 to 2019. The location of rheumatology practice was determined by billing tax identification and mapped. Demographics of physicians exiting or entering the rheumatology workforce were compared separately to those stable by logistic regression.ResultsThe clinically active adult rheumatology workforce identified in US Medicare in 2019 was 5,667 rheumatologists and 379 APPs. From 2009 to 2020, the number of rheumatologists increased 23% and the number of APPs increased 141%. There was an increase in female rheumatologists over time, rising to 43% in 2019. Women and those employed by a health care system were more likely to exit, and those in a small practice or in the South were less likely to exit.ConclusionThe overall number of clinically active rheumatology providers grew more than 20% over the last decade to a high of 6,036 in 2020, although this rate of growth appears to be flattening off in later years.

Abstract

In this experiment, egg white protein microparticles (EWPM) were used as a lipid substitute matrix to investigate the effects of EWPM/xanthan gum (XG) blend concentration, pH, sodium chloride concentration, sugar concentration, and homogenization conditions on the rheological properties of ultra-low-fat salad dressing products. The results showed that XG had a significant thickening effect on EWPM-based ultra-low-fat salad dressing. However, excess XG led to a decrease in the resilience of low-fat salad dressing. The effects of basic seasoning components on the quality of ultra-low-fat salad dressing were significantly different. pH and salt concentration had a significant impact on the viscosity of the salad dressing system, while sugar addition had a relatively smaller impact on the viscosity. Moderate colloid mill homogenization speed and time reduced the particle size of the product, thereby increasing the internal uniformity and significantly improving the viscosity of ultra-low-fat salad dressing. This study provides a clearer direction for the optimization of low-fat salad dressing.

Abstract

BACKGROUND: The increasing use of activity trackers in mobile health studies to passively collect physical data has shown promise in lessening participation burden to provide actively contributed patient-reported outcome (PRO) information. OBJECTIVE: The aim of this study was to develop machine learning models to classify and predict PRO scores using Fitbit data from a cohort of patients with rheumatoid arthritis. METHODS: Two different models were built to classify PRO scores: a random forest classifier model that treated each week of observations independently when making weekly predictions of PRO scores, and a hidden Markov model that additionally took correlations between successive weeks into account. Analyses compared model evaluation metrics for (1) a binary task of distinguishing a normal PRO score from a severe PRO score and (2) a multiclass task of classifying a PRO score state for a given week. RESULTS: For both the binary and multiclass tasks, the hidden Markov model significantly (P
