“…Results were consistent across all sex, ethnicity, and SES groups (interaction P > 0.05). CONCLUSIONS: Serial measures of patient-reported symptoms and HRQoL are significant and consistent predictors of outcomes among different groups with HF and provide the potential for a patient-centered and pragmatic approach to risk stratification.…”

“…INTRODUCTION: Based on the long-lasting diabetes management challenges in the United States, the objective was to examine glycemic levels among a nationally representative sample of people with diabetes stratified by prescribed antihyperglycemic treatment regimens and contextual factors. METHODS: This serial cross-sectional study used United States population-based data from the 2015 to March 2020 National Health and Nutrition Examination Surveys (NHANES). …”

“…The isolate B. subtilis BG01-4(TM) is a proprietary strain developed by Vernx Biotechnology through accumulating mutations within the BG01-4(TM) genome in a serial batch culture. Strain BG01-4(TM) was provided as a non-spore-forming B. subtilis , but a positive sporulation status for BG01-4(TM) was confirmed through in vitro testing and suggested that selection for the sporulation defective genes could occur within an environment that would select against sporulation. …”

“…CONCLUSION: The probe resistance is a useful predictive factor for successful EBUS-GS-TBLB diagnosis of solid and positive-bronchus-sign PPLs where the probe was located within the lesion. Four serial biopsies are appropriate for both probe resistance type II and type III, and additional diagnostic procedures are needed for type I.…”
