Costs and cost-effectiveness of an infection prevention bundle to reduce neonatal sepsis and mortality in Zambia
The Sepsis Prevention in Neonates in Zambia (SPINZ) trial was a prospective observational cohort study conducted in the neonatal intensive care unit of the University Teaching Hospital in Lusaka, Zambia. Introduction of an infection prevention and control (IPC) bundle reduced hospital-associated mortality, total mortality, suspected sepsis, and confirmed bloodstream infections. This companion analysis was undertaken to analyze intervention costs …
Transmission dynamics of Klebsiella pneumoniae in a neonatal intensive care unit in Zambia before and after an infection control bundle
Klebsiella pneumoniae is a leading cause of neonatal sepsis in low- and middle-income countries, with antimicrobial resistance (AMR) significantly contributing to mortality. We used whole genome sequencing to explore the impact of an infection prevention and control (IPC) intervention on K. pneumoniae strains and transmission dynamics responsible for sepsis in a Zambian neonatal unit. Blood culture isolates were collected during the Sepsis Preven…
Physiological Markers of Early Social Skills in Rural South Africa
Early social skills underlie the development of crucial regulatory and behavioral processes across childhood. EEG frontal alpha asymmetry and heart rate variability are two physiological markers that have been extensively studied in relation to social skills in high‐income country (HIC) samples. The prevalence of adversities in low‐ and middle‐income countries (LMICs) is linked to pervasive deficits in early social skills, yet little is known abo…
Aetiology of diarrhoea in children aged zero to nine years in low- and middle-income countries
Head Circumference Versus Length and Weight Deficits up to 2 Years of Age in Bangladesh
Infant undernutrition, defined by length- and weight-based indices, is common in low- and middle-income countries (LMICs), but corresponding deficits in head size have received less attention. In a cohort of term newborns in Dhaka, Bangladesh, we compared the severity of deficits (vs. World Health Organization Growth Standards) in head circumference (HC), length and weight at birth and every 3 months until 2 years of age (n range across timepoint…
Spatial modelling to identify high-risk zones for the transmission of cutaneous leishmaniasis in hyperendemic urban environments
Undernutrition in older children and adolescents in peri-urban Zambia
Background: Adolescents make up roughly a quarter of the population in Zambia; however, most nutrition-related programming is targeted at the under-five population. Understanding the scale of undernutrition in older children and adolescents is fundamental to alleviating food insecurity and addressing undernutrition across all age groups. Methods: A cross-sectional survey was performed in four low-income, peri-urban compounds in Chilanga District …

Risk factors for community-acquired bacterial infection among young infants in South Asia
OBJECTIVE: Risk factors predisposing infants to community-acquired bacterial infections during the first 2 months of life are poorly understood in South Asia. Identifying risk factors for infection could lead to improved preventive measures and antibiotic stewardship. METHODS: Five sites in Bangladesh, India and Pakistan enrolled mother-child pairs via population-based pregnancy surveillance by community health workers. Medical, sociodemographic …
Adherence to and enforcement of non-pharmaceutical interventions (NPIs) for Covid-19 prevention in Nigeria, Rwanda, and Zambia
Introduction In the early parts of the COVID-19 pandemic, non-pharmaceutical interventions (NPIs) were implemented worldwide, including in sub-Saharan Africa, to prevent and control SARS-CoV-2 transmission. This mixed-methods study examines adherence to and enforcement of NPIs implemented to curb COVID-19 in Nigeria, Rwanda, and Zambia, leading up to the 10,000 th case of laboratory-confirmed COVID-19 in each country. Additionally, we aim to eval…
Importance of breastfeeding and complementary feeding for management and prevention of childhood diarrhoea in low- and middle-income countries
Background: Early and exclusive breastfeeding have been shown to protect young infants from all-cause and diarrhoea-related mortality. Ideally breastfeeding should be initiated within the first hour of birth. Despite efforts to increase rates of early and exclusive breastfeeding in low- and middle-income countries (LMICs), challenges with uptake remain. This analysis reviews trends in early and exclusive breastfeeding, and the impact of infant fe…

Real-time Feedback to Improve HIV Treatment Adherence in Pregnant and Postpartum Women in Uganda
We assessed an intervention aimed at improving adherence to antiretroviral therapy (ART) among pregnant and postpartum women living with HIV (PPWLH). We randomized 133 pregnant women initiating ART in Uganda to receive text reminders generated by real time-enabled electronic monitors and data-informed counseling through 3 months postpartum (PPM3) or standard care. Intention-to-treat analyses found low adherence levels and no intervention impact. …
If we build it, will they come? Results of a quasi-experimental study assessing the impact of maternity waiting homes on facility-based childbirth and maternity care in Zambia
INTRODUCTION: Maternity waiting homes (MWHs) aim to increase access to maternity and emergency obstetric care by allowing women to stay near a health centre before delivery. An improved MWH model was developed with community input and included infrastructure, policies and linkages to health centres. We hypothesised this MWH model would increase health facility delivery among remote-living women in Zambia. METHODS: We conducted a quasi-experimenta…

We explored the scope, reach, quality, and cultural security of health and social services available to Aboriginal and/or Torres Strait Islander families in Western Australia (WA), from the point of view of staff from the services. We recruited staff from health and social services for Aboriginal people i…
Retention in HIV Care Among HIV-Seropositive Pregnant and Postpartum Women in Uganda
Effectiveness of community outreach HIV prevention programs in Vietnam
Outreach programs appear to have reduced risky sexual behaviors and increased use of HIV testing services among high-risk populations in Vietnam. These programs can play a key role in reducing gaps in the HIV care cascade, achieving the global 90-90-90 goals, and creating an AIDS-free generation
How a woman's interpersonal relationships can delay care-seeking and access during the maternity period in rural Zambia
To reduce maternal mortality, countries must continue to seek ways to increase access to skilled care during pregnancy and delivery. In Zambia, while antenatal attendance is high, many barriers exist that prevent women from delivering with a skilled health provider. This study explores how the individuals closest to a pregnant woman in rural Zambia can influence a woman's decision to seek and her ability to access timely maternity care. At four r…
Vitamin D status is associated with underweight and stunting in children aged 6–36 months residing in the Ecuadorian Andes
Objective There is limited knowledge on vitamin D status of children residing in the Andes and its association with undernutrition. We evaluated the vitamin D status of children residing in a low socio-economic status (SES) setting in the Ecuadorian Andes and assessed the association between vitamin D status, stunting and underweight. We hypothesized that children who were underweight would have lower serum 25-hydroxyvitamin D (25(OH)D) levels an…

Barriers to adherence to antiretroviral medications among patients living with HIV in southern China
Although China's government is rapidly expanding access to antiretroviral therapy, little is known about barriers to adherence among Chinese HIV-infected patients, particularly among injection drug users. To better understand barriers to antiretroviral treatment adherence, we conducted a qualitative research study, using both focus group and key informant methods, among 36 HIV-positive men and women in Dali, in southwestern China. All interviews …
Using Electronic Drug Monitor Feedback to Improve Adherence to Antiretroviral Therapy Among HIV-Positive Patients in China
Effective antiretroviral therapy (ART) requires excellent adherence. Little is known about how to improve ART adherence in many HIV/AIDS-affected countries, including China. We therefore assessed an adherence intervention among HIV-positive patients in southwestern China. Eighty subjects were enrolled and monitored for 6 months. Sixty-eight remaining subjects were randomized to intervention/control arms. In months 7-12, intervention subjects were…
Availability and utilization of malaria prevention strategies in pregnancy in eastern India
A disconnect remains between routine antenatal practices in India and known strategies to prevent and treat malaria in pregnancy. Prevention strategies, in particular the use of insecticide-treated bednets, are underutilized. Gaps highlighted by this study combined with recent estimates of the prevalence of malaria during pregnancy in these areas should be used to revise governmental policy and target increased educational efforts among health ca…
