Associations of retention in care by visits or lupus-specific labs with acute care among young adults: A medicare cohort study.

ObjectiveWhile quality lupus care is associated with lower lupus-related damage, the impact of access and process quality measures on other lupus outcomes remains unclear. Given high acute care in young adults, our objective was to evaluate two process quality measures, visit-based retention in lupus care and receipt of lupus-specific serologic testing, and associations with subsequent acute care use.MethodsThis cohort study used a 20% national sample of young adult (ages 18-35) Medicare beneficiaries with lupus to first measure visit-based retention in rheumatology care and receipt of ≥1 complement or dsDNA test over 1 year.

Inequality in the shadow: The role of private tutoring in SES achievement gaps.

Despite the rapid growth of private tutoring, previous studies have not systematically addressed its implications for socioeconomic status (SES) disparities in education, as they have only separately examined differential access to and the effects of private tutoring. This study directly estimates the causal contribution of private tutoring to SES disparities in educational achievement and cognitive ability among Chinese middle school students. Using nationally representative longitudinal data and a novel gap-closing approach, we find that unequal access to private tutoring does not uniformally result in significant learning gaps between high- and low-SES students.

Based on technical adjustment, CEET balance worldwide during 2006-2016 was calculated and compared to avoid false transfer. This study also explored the influencing factors of CEET balance and identified the transfer pathway of China.

Associations of Postdischarge Follow-Up With Acute Care and Mortality in Lupus: A Medicare Cohort Study.

Objective: Patients with systemic lupus erythematosus experience the sixth highest rate of 30-day readmissions among chronic diseases. Timely postdischarge follow-up is a marker of ambulatory care quality that can reduce readmissions in other chronic conditions. Our objective was to test the hypotheses that 1) beneficiaries from populations experiencing health disparities, including patients from disadvantaged neighborhoods, will have lower odds of completed follow-up, and that 2) follow-up will predict longer time without acute care use (readmission, observation stay, or emergency department visit) or mortality.

Development and validation of the SARICA score to predict survival after return of spontaneous circulation in out of hospital cardiac arrest using an interpretable machine learning framework.

FOXA2 inhibits doxorubicin-induced apoptosis via transcriptionally activating HBP rate-limiting enzyme GFPT1 in HCC cells.

Apoptosis plays an important role in both carcinogenesis and cancer treatment. Understanding the mechanisms through which resistance to apoptosis occurs in cancer cells has huge implications for cancer treatment. Although pieces of evidence have shown that elevated levels of global O-GlcNAcylation play an anti-apoptotic role in myriad cancers, the underlying mechanism is still ambiguous.

Application of micro-nanostructured magnetite in separating tetrabromobisphenol A and hexabromocyclododecane from environmental water by magnetic solid phase extraction.
