Metric and Levi-Civita Connections on Regular Hom-Lie-Rinehart Algebras

In this paper, we study regular Hom-Lie-Rinehart algebras and extend several classical geometric notions to this framework. In particular, we develop the theory of pseudo-Riemannian metrics, connections, curvature tensors, and torsion tensors in the setting of regular Hom-Lie-Rin...

National Implementation of a Tuberculosis Sample Referral Network to Expand Access to Molecular Diagnosis in the Republic of Congo: Pilot Evaluation and Programmatic Analysis (2023–2025)

Background: Limited access to rapid molecular diagnostics remains a major barrier to timely tuberculosis (TB) detection and drug-resistance surveillance in resource-constrained settings. In the Republic of Congo, GeneXpert MTB/RIF platforms remain concentrated in a few laboratori...

One in seven has severe pain: a point-prevalence study of hospitalised patients across Africa

ABSTRACT: Acute pain in hospitalised patients is common, yet African data are scarce. We conducted a prospective point-prevalence study of hospitalised adult patients across Africa to determine acute pain prevalence and severity and investigate associations of pain with critical...

Low practical knowledge but high willingness to use malaria rapid diagnostic tests among healthcare workers in the Republic of Congo

BACKGROUND: Malaria rapid diagnostic tests (mRDTs) are essential for early detection and effective management of malaria, but their success depends on healthcare workers' (HCWs) knowledge, attitudes, and practices regarding their use. This study described these factors and aimed...
