From January 2008 to December 2018, 1348 HIV-exposed infants were born in Porto Alegre, Brazil; 18.8% had adverse infant outcomes (AIO) including vertical transmission (1.9%), stillbirth/neonatal death (4.0%) and loss to follow-up before HIV diagnosis (12.9%). Timing of maternal HIV diagnosis was not associated with AIO but absent antiretroviral therapy use was. Lack of maternal antiretroviral therapy use is a significant risk factor for AIO., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 Wolters Kluwer Health, Inc.

Objectives: SARS-CoV-2 infection is a known risk factor for adverse health outcomes in pregnancy, affecting both maternal and neonatal health. Mounting evidence suggests that even a single dose of an approved COVID-19 vaccine protects against severe SARS-CoV-2 infection and is safe for both pregnant persons and neonates. Southern Brazil was heavily affected by the COVID-19 pandemic, and the protective effects of the vaccine on maternal and neonatal health are not well described. This study aims to examine the protective effects of maternal COVID-19 vaccination on both maternal and neonatal outcomes following SARS-CoV-2 infection during pregnancy., Methods: This is a retrospective cohort study that leveraged medical data from a tertiary center in South Brazil to compare maternal and infant outcomes between hospitalized pregnant persons with and without SARS-CoV-2 infection between 1 March 2020, and 1 March 2023., Results: In total, 524 patients were enrolled, including 275 pregnant patients with confirmed SARS-CoV-2 infection and 249 without infection. SARS-CoV-2 infection was associated with maternal ventilator support (adjusted Risk Ratio [aRR] = 1.48, 95% Confidence Interval [95% CI]: 1.08-2.03), while receipt of at least one dose of COVID-19 vaccine was associated with protection against maternal sepsis (aRR = 0.14, 95% CI: 0.03-0.56), intensive care unit (ICU) admission (aRR = 0.27, 95% CI: 0.10-0.68), need for ventilator support (aRR = 0.60, 95% CI: 0.43-0.84), infant admission to the neonatal intensive care unit (NICU) (aRR = 0.62, 95% CI: 0.47-0.82), and neonatal respiratory distress (aRR = 0.60, 95% CI: 0.43-0.83)., Conclusions: These findings further underscore the importance of maternal vaccination against COVID-19 during pregnancy. Even one dose of vaccine was protective against a variety of maternal and neonatal outcomes. Prenatal care should encourage COVID-19 vaccination in pregnancy.

Background: Syphilis coinfection among pregnant people living with HIV (PLH) may worsen pregnancy outcomes. We evaluated the impact of syphilis coinfection on pregnancies in south Brazil., Methods: Data were extracted from hospital records between January 1, 2008, and December 31, 2018. Preterm birth (PTB), low birth weight (LBW <2500 g), and a composite adverse infant outcome (AIO: HIV vertical transmission, loss to follow-up before HIV diagnosis, stillbirth, congenital syphilis) were evaluated among pregnancies without HIV and syphilis (PWOH + S), PLH monoinfection, syphilis monoinfection (PLS), and PLH with syphilis (PLH + S)., Results: Among 48,685 deliveries where patients were tested for HIV and syphilis, 1353 (2.8%) occurred in PLH; of these, 181 (13.4%) were HIV/syphilis coinfected (PLH + S). Among PLH, 2.4% of infants acquired HIV and 13.1% were lost to follow-up before HIV diagnosis. Among all PLS, 70.5% of infants acquired congenital syphilis. Across the cohort, 1.2% stillbirths/neonatal deaths occurred. Thirty-seven percent of PLH + S did not initiate antiretroviral therapy versus 15.4% of PLH monoinfection ( P < 0.001). Less than half (37.6%) of PLH + S had VDRL titers ≥1:16 compared with 21.7% of PLS only ( P < 0.001). Among PLH, syphilis coinfection and unknown/high VDRL titers (≥1:16) increased AIO risk more (adjusted relative risk [aRR], 3.96; 95% confidence interval [CI], 3.33-4.70) compared with low VDRL titers (≤1:8; aRR, 3.51; 95% CI, 2.90-4.25). Unsuppressed viremia (≥50 copies/mL) was associated with risk of PTB (aRR, 1.43; 95% CI, 1.07-1.92) and AIO (aRR, 1.38; 95% CI, 1.11-1.70) but not LBW. Lack of prenatal care was significant in predicting PTB and LBW in all PLH and PLS monoinfection., Conclusions: Syphilis coinfection worsens AIOs in all women and compounds negative effects of HIV infection during pregnancy. Effective syphilis treatment and HIV viral load suppression are paramount for optimal obstetric care., Competing Interests: Conflict of Interest and Sources of Funding: The authors have no competing interests or conflicts to declare., (Copyright © 2024 American Sexually Transmitted Diseases Association.

Objective : While reminder-based electronic monitoring systems have shown promise in enhancing inhaled corticosteroid (ICS) adherence in select populations, more engaging strategies may be needed in families of children with high-risk asthma. This study assesses the acceptability and feasibility of gain-framed ICS adherence incentives in families of urban, minority children with frequent asthma hospitalization. Methods : We enrolled children aged 5-11 years with multiple yearly asthma hospitalizations in a 2-month, mixed methods, ICS adherence incentive pilot study. All participants received inhaler sensors and a smartphone app to track ICS use. During month 1, families received daily adherence reminders and weekly feedback, and children earned up to $1/day for complete adherence. No reminders, feedback, or incentives were provided in month 2. We assessed feasibility and acceptability using caregiver surveys and semi-structured interviews and ICS adherence using electronic monitoring data. Results: Of the 29 families approached, 20 enrolled (69%). Participants were primarily Black (95%), publicly insured (75%), and averaged 2.9 asthma hospitalizations in the prior year. Fifteen of the 16 caregivers (94%) surveyed at month 2 liked the idea of receiving adherence incentives. Mean adherence was significantly higher in month 1 compared with month 2 (80% vs. 33%, mean difference = 47%; 95% CI [33, 61], p  < 0.001). Caregivers reported that their competing priorities often limited adherence, while incentives helped motivate child adherence. Conclusions: ICS adherence incentives were acceptable and feasible in a high-risk cohort of children with asthma. Future studies should assess the efficacy of adherence incentives in enhancing ICS adherence in high-risk children.
