  • Prevalence and transmission of HIV-1 drug resistance mutations among patients with treatment failure and newly diagnosed people in Liangshan Prefecture, China, in 2021–2023

    Open Access•Rong Pei, Yulian Zhang et al.•ARTICLE•Frontiers in Public Health•2025

    Introduction: Despite expanded antiretroviral therapy (ART) in China, HIV transmission persists. Liangshan Prefecture is one of the areas in China most severely affected by HIV, with high levels of drug resistance. A deeper understanding of HIV-1 drug resistance can lead to improvements in current treatment policies. Methods: We conducted an analysis of HIV drug resistance mutations (DRMs) among patients with treatment failure and people newly di…

  • Global associations of key populations with HIV-1 recombinants

    Open Access•Nkazi Nchinda, Ramyiadarsini Elangovan et al.•ARTICLE•Frontiers in Public Health•2023

  • Maternal and Neonatal Morbidity and Mortality Among Pregnant Women With and Without Covid-19 Infection

    Open Access•Jose Villar, Joris Hemelaar et al.•ARTICLE•JAMA Pediatrics•2021

    Importance: Detailed information about the association of COVID-19 with outcomes in pregnant individuals compared with not-infected pregnant individuals is much needed. Objective: To evaluate the risks associated with COVID-19 in pregnancy on maternal and neonatal outcomes compared with not-infected, concomitant pregnant individuals. Design, Setting, and Participants: In this cohort study that took place from March to October 2020, involving 43 i…

  • International standards for newborn weight, length, and head circumference by gestational age and sex

  • Epidemiological differences among birth weight and gestational age subgroups of newborns

    Open Access•Lenore J Launer, Jose Villar et al.•ARTICLE•American Journal of Human Biology•1991

    For a sample of 16,113 women who received prenatal care from the Guatemalan Social Security Institute Hospital, we described the distribution of birth weight and gestational age subgroups and the association between known epidemiologic risk factors and the odds for 1) an appropriate‐weight‐for‐gestational‐age preterm vs. a small‐for‐gestational‐age term infant, 2) a small‐for‐gestational‐age preterm vs. a small‐for‐gestational‐age term infant, an…
