Abstract
OBJECTIVES Current WHO guidelines recommend the treatment of all HIV-infected individuals with antiretroviral therapy (ART) to improve survival and quality of life, and decrease infection of others. MaxART is the first implementation trial of this strategy embedded within a government-managed health system, and assesses mortality as a secondary outcome. Because primary findings strongly supported scale-up of the 'treat all' strategy (hereafter Treat All), this analysis examines mortality as an additional indicator of its impact. METHODS MaxART was conducted in 14 Eswatinian health clinics through a clinic-based stepped-wedge design, by transitioning clinics from then-national standard of care (SoC) to the Treat All intervention. All-cause, disease-related, and HIV-related mortality were analysed using the Cox proportional hazards model, censoring SoC participants at clinic transition. Median follow-up time among study participants was 292 days. There were 36/2034 deaths in SoC (1.77%) and 49/1371 deaths in Treat All (3.57%). RESULTS Between September 2014 and August 2017, 3405 participants were enrolled. In SoC and Treat All interventions, respectively, the multivariable-adjusted 12-month all-cause mortality rates were 1.42% [95% confidence interval (CI): 0.66-2.17] and 1.60% (95% CI: 0.78-2.40), disease-related mortality rates were 1.02% (95% CI: 0.40-1.64) and 1.10% (95% CI: 0.46-1.73), and HIV-related mortality rates were 1.03% (95% CI: 0.40-1.65) and 0.99% (95% CI: 0.40-1.58). Treat All had no impact on all-cause [hazard ratio (HR) = 1.12, 95% CI: 0.58-2.18, P = 0.73], disease-related (HR = 1.04, 95% CI: 0.52-2.11, P = 0.90), or HIV-related mortality (HR = 0.93, 95% CI: 0.46-1.87, P = 0.83). CONCLUSION There was no immediate benefit of the Treat All strategy on mortality, nor evidence of harm. Longer follow-up of participants is needed to establish long-term consequences.

Abstract
OBJECTIVES To investigate uptake and provision of antenatal care (ANC) services in the Uzazi Bora project: a demonstration-intervention project for Safe Motherhood and prevention of mother-to-child transmission of HIV in Kenya. METHODS Data were extracted from antenatal clinic, laboratory and maternity ward registers of all pregnant women attending ANC from January 2004 until September 2006 at three antenatal clinics in Mombasa and two in rural Kwale district of Coast Province, Kenya (n = 25 364). Multiple logistic and proportional odds logistic regression analyses assessed changes over time, and determinants of the frequency and timing of ANC visits, uptake of HIV testing, and provision of iron sulphate, folate and single-dose nevirapine (sd-NVP). RESULTS About half of women in rural and urban settings (52.2% and 49.2%, respectively) attended antenatal clinics only once. Lower parity, urban setting, older age and having received iron sulphate and folate supplements during the first ANC visit were independent predictors of more frequent visits. The first ANC visit occurred after 28 weeks of pregnancy for 30% (5894/19 432) of women. By mid-2006, provision of nevirapine to HIV-positive women had increased from 32.5% and 11.7% in rural and urban clinics, to 67.0% and 74.6%, respectively. Equally marked improvements were observed in the uptake of HIV testing and the provision of iron sulphate and folate. CONCLUSION Provision of ANC services, including sd-NVP, increased markedly over time. While further improvements in quality are necessary, particular attention is needed to implement evidence-based interventions to alter ANC utilization patterns. Encouragingly, improved provision of basic essential obstetric care may increase attendance.
