Effect mechanisms of different malaria chemoprevention regimens in pregnancy on infant growth outcomes: causal mediation analysis of a randomized controlled trial

Anna Nguyen, Joaniter I Nankabirwa, Abel Kakuru, Michelle E. Roh et autres

Abstract Introduction Intermittent preventive treatment in pregnancy (IPTp) with sulfadoxine-pyrimethamine (SP) has become less effective at preventing malaria due to rising parasite resistance. IPTp with dihydroartemisinin-piperaquine (DP) alone or in combination with SP (DP+SP) dramatically lowers the risk of malaria in pregnancy …

Impact of Intermittent Preventive Treatment for Malaria in Pregnancy With Sulfadoxine-Pyrimethamine, Dihydroartemisinin-Piperaquine, and Their Combination on Infant Outcomes: A Randomized Controlled Trial

Joaniter Immaculate Nankabirwa, Abel Abel, Anna Nguyen, Michelle E. Roh et autres

BACKGROUND: Intermittent preventive treatment in pregnancy (IPTp) with dihydroartemisinin-piperaquine (IPTp-DP) is more effective than sulfadoxine-pyrimethamine (IPTp-SP) at reducing the burden of malaria in pregnancy in settings with high SP resistance. Paradoxically, IPTp-DP has been associated with lower birth weights compared with IPTp-SP. …

Rainfall and temperature influence effectiveness of on-site sanitation intervention against E. coli contamination in Bangladeshi households

Caitlin G. Niven, M. S. Islam, Anna Nguyen, Andrew N. Mertens et autres

Weather can influence the environmental spread and survival of fecal pathogens, potentially affecting the effectiveness of water, sanitation, and hygiene (WASH) interventions. We assessed whether rainfall and temperature modified effects of an on-site sanitation intervention on fecal contamination among households in the …

Acceptability and feasibility of virtual reality multisensory environments for individuals with neurodevelopmental disorders: professional caregiver perspectives

Ye Ji Yi, Anna Nguyen, Negar Heidari Matin, Ziho Kang et autres

This study investigates the acceptability and feasibility of Virtual Reality Multisensory Environments (VR MSEs) to support sensory exploration among individuals with neurodevelopmental disorders (NDD). To assess user acceptance of VR MSEs, data were collected from 40 professional caregivers, including occupational therapists, special …

Potential pathogens and antimicrobial resistance genes in household environments: a study of soil floors and cow dung in rural Bangladesh

Anna Nguyen, Kalani Ratnasiri, Gabriella Barratt Heitmann, Sumaiya Tazin et autres

ABSTRACT In low- and middle-income countries, living in homes with soil floors and animal cohabitation may expose children to fecal organisms, increasing the risk of enteric and antimicrobial-resistant infections. Our objective was to understand whether cow cohabitation in homes with soil floors …

Which social media platforms facilitate monitoring the opioid crisis?

Kristy A. Carpenter, Anna Nguyen, Delaney A. Smith, Issah Abubakari Samori et autres

Social media can provide real-time insight into trends in substance use, addiction, and recovery. Prior studies have used platforms such as Reddit and X (formerly Twitter), but evolving policies around data access have threatened these platforms' usability in research. We evaluate the …

Pathways through which water, sanitation, hygiene, and nutrition interventions reduce antibiotic use in young children: a mediation analysis of a cohort nested within a cluster-randomized trial

Anna Nguyen, Gabby Barratt Heitmann, Andrew N. Mertens, Sania Ashraf et autres

Background: Low-cost, household-level water, sanitation, and hygiene (WASH) and nutrition interventions can reduce pediatric antibiotic use, but the mechanism through which interventions reduce antibiotic use has not been investigated. Methods: We conducted a causal mediation analysis using data collected between September 2013 …

Associations between weather extremes and faecal contamination along pathogen transmission pathways in rural Bangladeshi households: a prospective observational study

Caitlin G. Niven, Mahfuza Islam, Anna Nguyen, Jessica Anne Grembi et autres

BACKGROUND: Weather extremes are predicted to influence pathogen exposure but their effects on specific faecal-oral transmission pathways are not well investigated. We evaluated associations between extreme rain and temperature during different antecedent periods (0-14 days) and Escherichia coli along eight faecal-oral pathways …

Author Correction: Early-childhood linear growth faltering in low- and middle-income countries

Jade Benjamin‐Chung, Andrew N. Mertens, John M. Colford, Alan Hubbard et autres

The code that we used to fit meta-analyses for the proportion of children stunted by age in Fig. 3a and Extended Data Figs. 8 – 10 incorrectly used the total number of children in the denominator for incidence, which incorrectly included children …

Associations between weather and Plasmodium vivax malaria in an Amazonian elimination setting: a distributed lag analysis from 2017–2024

Gabriella Barratt Heitmann, Xue Wu, Anna Nguyen, Astrid Altamirano-Quiroz et autres

ABSTRACT Background Plasmodium vivax ( Pv ) is the predominant malaria species in countries approaching elimination. Environmental factors can guide intervention targeting.Yet, research that considers the long-term relapse periodicity of Pv is limited, particularly in Latin America. Methods We merged Pv malaria …
