Evaluating the role of serum cystatin C as a circulating biomarker of diabetic retinopathy from a rural Indian population.

Purpose: This study aimed to evaluate serum cystatin C as a potential biomarker for diabetic retinopathy (DR) in a rural Indian population, addressing the urgent need for effective screening tools amidst rising diabetes prevalence.

Materials And Methods: A cross-sectional study recruited 112 patients with diabetes mellitus from Sambalpur, Odisha, India, categorized into groups with and without DR. Serum cystatin C levels were measured alongside clinical and demographic parameters, using established diagnostic methods.

Change in Postpartum Visit and Contraception Rates Pre-COVID-19 to Post-Lockdown in Six U.S. Federally Qualified Health Centers.

Postpartum care, including contraception, benefits maternal health and decreases mortality, which increased in the United States with COVID-19. Pandemic disruptions to postpartum health care access in vulnerable populations are not well understood. We utilize electronic health record (EHR) data for prenatal patients ( = 2,265) at six urban Federally Qualified Health Centers (FQHCs) from one year prepandemic (January 1, 2019) through one year after the first stay-at-home orders ("lockdown") (March 31, 2021).

User Perceptions of Wearability of Knitted Sensor Garments for Long-Term Monitoring of Breathing Health: Thematic Analysis of Focus Groups and a Questionnaire Survey.

Background: Long-term unobtrusive monitoring of breathing patterns can potentially give a more realistic insight into the respiratory health of people with asthma or chronic obstructive pulmonary disease than brief tests performed in medical environments. However, it is uncertain whether users would be willing to wear these sensor garments long term.

Objective: Our objective was to explore whether users would wear ordinary looking knitted garments with unobtrusive knitted-in breathing sensors long term to monitor their lung health and under what conditions.

Improved Adsorption of Organic Dyes onto a Polypyrrole/Tannic Acid Nanocomposite.

Methyl orange (MO) and methylene blue (MB) dyes are toxic and carcinogenic; thus, their presence in water bodies has been a major concern. Designing an efficient adsorbent for removal of these dyes is a scientific challenge for researchers. In this work, a polypyrrole-tannic acid nanocomposite was prepared via a chemical oxidation method and used as a novel adsorbent for removing these toxic dyes.
