The physicochemical properties of aerosols, including hygroscopicity, phase state, pH, and viscosity, influence important processes ranging from virus transmission and pulmonary drug delivery to atmospheric light scattering and chemical reactivity. Despite their importance, measurements of these key properties in aerosols remain experimentally challenging due to small particle sizes and low mass densities in air. Fluorescence probe spectroscopy is one of the only analytical techniques that is capable of experimentally determining these properties in situ in a nondestructive and minimally perturbative manner.

The current study aimed to explore the experiences of partners of individuals with diabetes and chronic kidney disease (CKD) who received a simultaneous pancreas and kidney transplant (SPKT) to understand the wider impact of SPKTs. Eight partners of recipients of SPKT were interviewed about their experiences before and after the transplant.

We sought to identify concurrent human infections, their phylogeny, and epidemiologic characteristics in a cohort of febrile patients enrolled from 2016-2019 at hospitals serving the epizootic area.
Methods: From September 2016 through May 2019, we conducted a prospective cohort study that enrolled febrile patients hospitalized at two hospitals in Moshi, Tanzania.
Maternal infections during pregnancy can increase the risk to offspring of developing a neurodevelopmental disorder. Given the global prevalence and severity of infection with Severe Acute Respiratory Syndrome related Coronavirus 2 (SARS-CoV-2), the objective of this study was to determine if in utero exposure to severe maternal SARS-CoV-2 infection alters infant neurodevelopmental outcomes at 12 months and to identify potential biological markers of adverse infant outcomes. Mother-infant dyads exposed to severe SARS-CoV-2 infection (requiring hospitalization) during pregnancy and age and sociodemographic matched control dyads were recruited from Monash Medical Centre, Australia in 2021/22 and prospectively assessed over 12 months.
