Synergistic label-free fluorescence imaging and miRNA studies reveal dynamic human neuron-glial metabolic interactions following injury.

Neuron-glial cell interactions following traumatic brain injury (TBI) determine the propagation of damage and long-term neurodegeneration. Spatiotemporally heterogeneous cytosolic and mitochondrial metabolic pathways are involved, leading to challenges in developing effective diagnostics and treatments. An engineered three-dimensional brain tissue model comprising human neurons, astrocytes, and microglia is used in combination with label-free, two-photon imaging and microRNA studies to characterize metabolic interactions between glial and neuronal cells over 72 hours following impact injury.

Factors influencing provider deviation from national HIV and nutritional guidelines for HIV-exposed children in western Kenya: a qualitative study.

Background: Malnutrition and HIV interact in a vicious cycle for HIV-exposed infants (HEIs), increasing vulnerability and the severity of each condition and contributing to poor health outcomes. We identified multi-level factors influencing provider adherence to Kenyan HIV and nutrition guidelines for HEIs.

Methods: We conducted six focus group discussions and seven in-depth interviews using a semi-structured question guide.

Residual next-day effects of alprazolam on psychomotor performance and simulated driving in healthy normal adults.

The prevalence of drugged driving has increased in the United States. Some drugged driving may be unintentional as prescription medications used as sleeping aids, like zolpidem, cause impairment after the predicted duration of therapeutic action has elapsed. The aim of this study was to determine if nighttime administration of alprazolam, a drug commonly prescribed off-label as a sleeping aid, impacts driving performance the following day.

The impact of COVID-19 national lockdowns on drug-resistant tuberculosis in KwaZulu-Natal, South Africa: A spatial analysis.

Purpose: We sought to understand the impact of the initial COVID-19 mitigation strategies in 2020 on drug-resistant (DR) TB diagnoses in KwaZulu-Natal province (KZN), South Africa.

Methods: We compared the number, spatial distribution, and characteristics of DR TB diagnoses before and after the initial COVID-19 lockdown on March 26th, 2020. Information on DR TB diagnoses was collected from the CONTEXT prospective cohort study and municipality characteristics were collected from Statistics South Africa.

Socioeconomic and fiscal returns of expanded investment in immunization: a case for life-course vaccination in Colombia.

Despite the health, societal, and economic benefits of immunization, many countries focus primarily on childhood immunizations and lack robust policies and sufficient resources for immunizations that can benefit populations across the life course. While the benefits of childhood vaccination are well documented, there is limited evidence on the financial and social return on investment that policymakers can use to inform decisions around administering a life-course immunization program. We developed a cost-benefit model from a societal perspective to evaluate the inclusion of 5 vaccines across the life course in Colombia's national immunization program.
