Zanzibar, a low-resource semiautonomous region of Tanzania, has an estimated prevalence of hepatitis B virus (HBV) infections of 3.6%. To assess the feasibility of care and treatment, a 5-year hepatitis B demonstration project was implemented in Zanzibar during January 2017-December 2021, following the 2015 WHO HBV care and treatment guidelines.

Background: In STREAM-1 (Strategic Reperfusion Early After Myocardial Infarction), excess intracranial hemorrhage occurred in patients aged ≥75 years receiving full-dose tenecteplase as part of a pharmaco-invasive strategy, whereas no further intracranial hemorrhage occurred after halving the tenecteplase dose. In STREAM-2 (Second Strategic Reperfusion Early After Myocardial Infarction), half-dose tenecteplase was an effective and safe pharmaco-invasive strategy in older patients with ST-segment-elevation myocardial infarction presenting within <3 hours, compared with primary percutaneous coronary intervention (PCI). We prespecified evaluating the efficacy and safety of a half-dose versus full-dose pharmaco-invasive strategy and compared the half-dose pharmaco-invasive strategy to primary PCI in patients aged ≥75 years.

This study presents surveillance data from 1 July 2003 to 30 June 2023 for community-associated methicillin-resistant (CA-MRSA) notified in the Kimberley region of Western Australia (WA) and describes the region's changing CA-MRSA epidemiology over this period. A subset of CA-MRSA notifications from 1 July 2003 to 30 June 2015 were linked to inpatient and emergency department records. Episodes of care (EOC) during which a positive CA-MRSA specimen was collected within the first 48 hours of admission and emergency presentations (EP) during which a positive CA-MRSA specimen was collected on the same day as presentation were selected and analysed further.

Article Synopsis
  • Sub-Saharan Africa has the highest chronic hepatitis B virus (HBV) infection rates globally, making national HBV prevalence estimates crucial for Kenya's viral hepatitis program.
  • In a study analyzing data from over 3,000 participants aged 15-64 in the 2018 Kenya Population-based HIV Impact Assessment, the national HBV prevalence was found to be 3.0%, equating to approximately 810,600 infected individuals in this age group.
  • The study revealed significant geographical variations in HBV prevalence, with higher rates in certain regions, among people living with HIV, older individuals, those with no formal education, and in lower economic groups; lack of formal education was notably linked to increased HBV infection risk.
