A retrospective 10-year review of neonatal HA-BSI was performed at Tygerberg Hospital's neonatal unit in Cape Town, South Africa. Neonatal clinical and laboratory data from 2014 to 2018 (Period 2) was compared with published data from 2009 to 2013 (Period 1). The neonatal unit's HA-BSI rate declined between periods from 3.9/1000 inpatient-days in Period 1 to 3.3/1000 inpatient-days in Period 2 (p = 0.002). Pathogen yield and blood culture contamination rate were unchanged (11.0% to 10.4%, p = 0.233; 5.1% to 5.3%, p = 0.636 respectively). Gram-negative pathogens predominated (1047/1636; 64.0%); Klebsiella species, Staphylococcus aureus, Serratia marcescens, Enterococcus species and Acinetobacter baumannii were the most frequent pathogens. Extended spectrum beta-lactamase production was observed in 319/432 (73.8%) of Klebsiella sp AMR profiles and inform empiric antibiotic recommendations for neonatal units in resource-limited settings. We aimed to study fatigue and sleep in registrars working 12-hour rotating shifts in our tertiary neonatal intensive unit. This study involved neonatal registrar's working day (0800-2100) and night (2030-0830) shifts. Participants maintained a sleep diary, answered a self-reported sleepiness questionnaire assessing subjective sleepiness, and performed a 10-minute psychomotor vigilance task (PVT) at the start and end of each shift. Primary outcomes (1) Fatigue at the (i) "start vs end" of day and night shifts, (ii) end of the "day vs night" shifts, and (iii) end of "first vs last shift" in block of day and night shifts. (2) Duration and quality of sleep before the "day vs night" shifts. Mean reaction time (RTM), relative coefficient of variation (RTCV), and lapses (reaction time > 500ms) were used as measures of
