Incidence, aetiology and short term outcomes of extreme hyperbilirubinaemia, in term infants born in the Western health subdistrict of Cape Town, South Africa between 2019 and 2020.

Extreme levels of bilirubin in newborn is a major cause of lifelong neurodevelopmental impairment, which places a financial burden on healthcare resources and caregivers. To determine the incidence, aetiology and short-term outcomes of extreme hyperbilirubinaemia in term infants born in a resource-limited setting. This is a retrospective observational study looking at term neonates with a birth weight ≥2500 g, born in the Western health subdistrict of Cape Town, South Africa, between 1 January 2019 and 31 December 2020, who were exposed to a serum bilirubin level of ≥430 μmol/L in the first week of life and received care in the public health system.

Intraoperative pectoral nerve blocks during cardiac implantable electronic device procedures.

Background: Cardiac implantable electronic device (CIED) procedures can cause significant postoperative pain. Opioid use for postoperative pain is associated with risk of persistent use. The benefits of pectoral nerve (PECs) blocks have been established for other chest wall surgeries, but adoption in electrophysiology has been limited.

The bii4africa dataset of faunal and floral population intactness estimates across Africa's major land uses.

Sub-Saharan Africa is under-represented in global biodiversity datasets, particularly regarding the impact of land use on species' population abundances. Drawing on recent advances in expert elicitation to ensure data consistency, 200 experts were convened using a modified-Delphi process to estimate 'intactness scores': the remaining proportion of an 'intact' reference population of a species group in a particular land use, on a scale from 0 (no remaining individuals) to 1 (same abundance as the reference) and, in rare cases, to 2 (populations that thrive in human-modified landscapes). The resulting bii4africa dataset contains intactness scores representing terrestrial vertebrates (tetrapods: ±5,400 amphibians, reptiles, birds, mammals) and vascular plants (±45,000 forbs, graminoids, trees, shrubs) in sub-Saharan Africa across the region's major land uses (urban, cropland, rangeland, plantation, protected, etc.

Identifying Origin of Nonpulmonary Vein Triggers Using 2 Stationary Linear Decapolar Catheters: A Novel Algorithm.

Background: Targeting nonpulmonary vein triggers (NPVTs) of atrial fibrillation (AF) after pulmonary vein isolation can be challenging. NPVTs are often single ectopic beats with a surface P-wave obscured by a QRS or T-wave.

Objectives: The goal of this study was to construct an algorithm to regionalize the site of origin of NPVTs using only intracardiac bipolar electrograms from 2 linear decapolar catheters positioned in the posterolateral right atrium (along the crista terminalis with the distal bipole pair in the superior vena cava) and in the proximal coronary sinus (CS).
