Tissue Resident CD8+T-cells as mediators of protective immunity in breastmilk transmission of HCMV.

While the role of breastmilk antibodies to protect infants from CMV has been investigated, the role of T-cells, have received little attention. We compared the frequency of memory T-cell populations in breastmilk between mothers of infants who acquired breastmilk HCMV (transmitters) and those with uninfected infants (non-transmitters). Non-transmitter moms had an increased frequency of CD8+ effector memory T-cells (Tem) in their breastmilk.

Antibiotic or gastric acid inhibitor use during pregnancy and postpartum depression: Population-based cohort study.

Introduction: Postpartum depression is one of the most common non-obstetric postnatal complications. As the microbiome (and gut-brain axis) as well as inflammation may be involved in the mechanism, we aimed to assess if antibiotic or gastric acid inhibition use during pregnancy affects the risk of postpartum depression (clinical diagnosis and/or antidepressant use up to 1 year after childbirth).

Material And Methods: This population-based cohort study used first singleton pregnancy resulting in a live birth in Sweden from 2006 to 2016.

Safety and immunogenicity of ChAdOx1 nCoV-19 (AZD1222) vaccine in adults in Kenya: a phase 1/2 single-blind, randomised controlled trial.

Background: There are limited data on the immunogenicity of coronavirus disease 2019 (COVID-19) vaccines in African populations. Here we report the immunogenicity and safety of the ChAdOx1 nCoV-19 (AZD1222) vaccine from a phase 1/2 single-blind, randomised, controlled trial among adults in Kenya conducted as part of the early studies assessing vaccine performance in different geographical settings to inform Emergency Use Authorisation.

Methods: We recruited and randomly assigned (1:1) 400 healthy adults aged ≥18 years in Kenya to receive ChAdOx1 nCoV-19 or control rabies vaccine, each as a two-dose schedule with a 3-month interval.

An assessment of primary health care costs and resource requirements in Kaduna and Kano, Nigeria.

Introduction: The availability of quality primary health care (PHC) services in Nigeria is limited. The PHC system faces significant challenges and the improvement and expansion of PHC services is constrained by low government spending on health, especially on PHC. Out-of-pocket (OOP) expenditures dominate health spending in Nigeria and the reliance on OOP payments leads to financial burdens on the poorest and most vulnerable populations.
