In the United States, patients with chronic conditions experience disparities in health outcomes across the care continuum. Among patients with multiple sclerosis, diabetic retinopathy, and lung cancer, there is a lack of evidence summarizing interventions to improve care and decrease these disparities. The aim of this rapid literature review was to identify interventions among patients with these chronic conditions to improve health and reduce disparities in screening, diagnosis, access to treatment and specialists, adherence, and retention in care.

- The past decade has seen a surge in electronic cigarette use, raising concerns about the health effects of secondhand exposure to e-cig particles.
- This study utilized a portable device called c-Air, enhanced by deep learning and holographic microscopy, to measure the volatility of exhaled e-cig aerosols in a vape shop over four days.
- Findings indicated that indoor vaping significantly increased the presence of volatile and semi-volatile particles in the air, suggesting a need for more research on the health impacts of these emissions.
Article Synopsis
- The study assessed particulate pollution and nicotine levels in six vape shops and their neighboring businesses in Southern California from February 2017 to October 2019.
- Vape shops showed significantly higher levels of particle number concentration (PNC) and particulate matter (PM) compared to nearby businesses and outdoor areas, with a strong correlation between the air quality in the vape shops and their neighbors, especially when doors were closed.
- Nicotine was detected in both environments, and the study found that factors like vaping density and air exchange rates influenced pollutant levels, highlighting concerns about the impact of e-cig usage on local air quality.
Article Synopsis
- The study focused on how the composition of e-liquids, specifically the propylene glycol (PG) to vegetable glycerin (VG) ratio and nicotine content, affects the aerosol emissions from electronic cigarettes (e-cigs).* -
- Ten different flavorless e-liquid mixtures were tested in a controlled chamber to measure particle concentration and size during and after puffing, revealing that nicotine significantly reduced particle emissions and that higher PG content also led to lower particulate matter.* -
- The findings suggest that e-liquid formulation can influence the exposure levels of e-cig aerosols, with nicotine and PG being key factors in determining how quickly particles dissipate in the environment.*
Organismal chemical tolerance is often used to assess ecological risk and monitor water quality, yet tolerance can differ between field- and lab-raised organisms. In this study, we examined how tolerance to copper (Cu) and tributyltin oxide (TBTO) in two species of marine copepods, Tigriopus japonicus and T. californicus, changed across generations under benign laboratory culture (in the absence of pre-exposure to chemicals).

Due to its cytotoxicity, genotoxicity, and adipogenicity observed in in vitro studies, bisphenol A diglycidyl ether (BADGE) may pose a health risk to humans. Quantifying BADGE exposure is an essential step to assess potential health risks associated with this ubiquitous compound widely used in certain plastic products. Due to the lack of endogenous sources for BADGE, bio-monitoring of BADGE and/or its hydrolytic metabolites (BADGE·H2O and BADGE·2H2O) can be a useful means to measure exposure.
