Childhood growth during recovery from acute illness in Africa and South Asia: a secondary analysis of the childhood acute illness and nutrition (CHAIN) prospective cohort.

Background: Growth faltering is well-recognized during acute childhood illness and growth acceleration during convalescence, with or without nutritional therapy, may occur. However, there are limited recent data on growth after hospitalization in low- and middle-income countries.

Methods: We evaluated growth following hospitalization among children aged 2-23 months in sub-Saharan Africa and South Asia.

Substitution of flavored cigarillos with menthol cigarettes among young adults in the U.S.

Background: Young adult cigarillo users often cite flavor as a primary reason for initiating and sustaining product use and are more likely to concurrently use other tobacco products such as menthol cigarettes. This study examines substitution with menthol cigarettes among cigarillo users facing a hypothetical ban on flavored cigarillos.

Methods: Current young adult (21-28 years) cigarillo users were recruited from October 2020 to April 2021 for an online survey about cigarillo and other tobacco use behaviors.

Engineering a sustainable future for point-of-care diagnostics and single-use microfluidic devices.

Single-use, disposable, point-of-care diagnostic devices carry great promise for global health, including meeting urgent needs for testing and diagnosis in places with limited laboratory facilities. Unfortunately, the production and disposal of single-use devices, whether in lateral flow assay, cartridges, cassettes, or lab-on-chip microfluidic format, also poses significant challenges for environmental and human health. Point-of-care devices are commonly manufactured from unsustainable polymeric materials derived from fossil sources.

Assessment of Groundwater Quality Using Water Quality Index from Selected Springs in Manga Subcounty, Nyamira County, Kenya.

We present the results of groundwater quality assessment that was done during the rainy season in November 2018 in the Manga region of Nyamira County, Kenya. Water samples were collected from three springs, Kiangoso, Kerongo, and Tetema, for the assessment. Water quality index was calculated based on pH, turbidity, nitrate, phosphate, calcium, magnesium, chloride, sulphates, fluoride, iron, total phosphorous, total hardness, total alkalinity, total dissolved solids, and total coliform.
