COVID-19 Vaccines Effectiveness and Safety in Trinidad and Tobago: A Systematic Review and Meta-Analysis.

This systematic review evaluated the effectiveness and side effects of various COVID-19 vaccines, with a focus on Trinidad and Tobago. The Pfizer-BioNTech and Moderna vaccines demonstrated the highest efficacy, particularly against COVID-19 variants, while Janssen and Sinopharm were comparatively less effective. mRNA vaccines, such as Pfizer-BioNTech and Oxford-AstraZeneca, were associated with more frequent and severe side effects, including soreness, fever, and cardiovascular issues.

Tipping the balance between and ligand conformers in multinuclear ethylzinc cyclophosphazenates.

Hexaanionic cyclophosphazenate ligands [(RN)PN] provide versatile platforms for the assembly of multinuclear metal arrays due to their multiple coordination sites and highly flexible ligand core structure. This work investigates the impact of incrementally increasing the steric demand of the ligand periphery on the coordination behavior of ethylzinc arrays. It shows that the increased congestion around the ligand sites is alleviated by progressive condensation with the elimination of diethylzinc.

Multiple cell types support productive infection and dynamic translocation of infectious Ebola virus to the surface of human skin.

Ebola virus (EBOV) causes severe human disease. During late infection, EBOV virions are on the skin's surface; however, the permissive skin cell types and the route of virus translocation to the epidermal surface are unknown. We describe a human skin explant model and demonstrate that EBOV infection of human skin via basal media increases in a time-dependent and dose-dependent manner.

Prioritising domains of glucocorticoid therapy to measure in trials: Results from a modified delphi exercise from the OMERACT glucocorticoid impact working group.

Introduction: There is no consensus amongst patients and healthcare professionals about how to measure important adverse effects of glucocorticoids (GCs) that includes the patient's perspective. The OMERACT GC Impact working group sought to identify the domains of greatest importance to both patients and healthcare professionals for use in a proposed core outcome set.

Methods: Patients and healthcare professionals participated in a Delphi consensus exercise to rate the importance of previously identified candidate domains.
