Finally, 2.0-2.3 μg m-3 should be considered as PM2.5 concentrations that are irreducible when setting voluntary targets for ambient levels in the area.Although integration of HIV and maternal health services is recommended by the World Health Organization, evidence to guide implementation is limited. We describe facility-level implementation of policies for integrating HIV care within maternal health services and explore experiences of service users and providers in rural Tanzania (Ifakara), South Africa (uMkhanyakude) and Malawi (Karonga). Policy in all countries included HIV testing during antenatal care (ANC), same-day antiretroviral therapy (ART) initiation for HIV-positive pregnant women, and postpartum referral to ART clinics, between six weeks (Malawi, South Africa) and two years after delivery (Tanzania). All facilities offered HIV testing within ANC, most commonly during the first visit. Although most women were comfortable with HIV testing, some felt that opting out would lead to sub-standard services. Some facilities conducted group post-test counselling for HIV-negative women, raising concerns of unintended HIV status disclosure. ART initiation was offered on the same day, the same room as an HIV diagnosis in >90% of facilities. Women's worries around postpartum referral included having unknown providers, insufficient privacy and queues. Adoption and implementation of policies on integrated HIV and maternal health services varied across settings. Patients' experiences of these policies may influence uptake and retention in care.Visual search is facilitated when the target is repeatedly encountered at a fixed position within an invariant (vs. randomly variable) distractor layout-that is, when the layout is learned and guides attention to the target, a phenomenon known as contextual cuing. Subsequently changing the target location within a learn
