JAMA Netw Open 2023 6 (4) e237396 IMPORTANCE: Associations between prenatal SARS-CoV-2 exposure and neurodevelopmental outcomes have substantial public health relevance. A previous study found no association between prenatal SARS-CoV-2 infection and parent-reported infant neurodevelopmental outcomes, but standardized observational assessments are needed to confirm this finding. OBJECTIVE: To assess whether mild or asymptomatic maternal SARS-CoV-2 infection vs no infection during pregnancy is associated with infant neurodevelopmental differences at ages 5 to 11 months. DESIGN, SETTING, AND PARTICIPANTS: This cohort study included infants of mothers from a single-site prospective cross-sectional study (COVID-19 Mother Baby Outcomes [COMBO] Initiative) of mother-infant dyads and a multisite prospective cohort study (Epidemiology of Severe Acute Respiratory Syndrome Coronavirus 2 in Pregnancy and Infancy [ESPI]) of pregnant individuals. A subset of ESPI participants was subsequently enrolled in the ESPI COMBO substudy. Participants in the ongoing COMBO study were enrolled beginning on May 26, 2020; participants in the ESPI study were enrolled from May 7 to November 3, 2021; and participants in the ESPI COMBO substudy were enrolled from August 2020 to March 2021. For the current analysis, infant neurodevelopment was assessed between March 2021 and June 2022. A total of 407 infants born to 403 mothers were enrolled (204 from Columbia University Irving Medical Center in New York, New York; 167 from the University of Utah in Salt Lake City; and 36 from the University of Alabama in Birmingham). Mothers of unexposed infants were approached for participation based on similar infant gestational age at birth, date of birth, sex, and mode of delivery to exposed infants. EXPOSURES: Maternal symptomatic or asymptomatic SARS-CoV-2 infection. MAIN OUTCOMES AND MEASURES: Infant neurodevelopment was assessed using the Developmental Assessment of Young Children, second edition (DAYC-2), adapted for telehealth assessment. The primary outcome was age-adjusted standard scores on 5 DAYC-2 subdomains: cognitive, gross motor, fine motor, expressive language, and receptive language. RESULTS: Among 403 mothers, the mean (SD) maternal age at delivery was 32.1 (5.4) years; most mothers were of White race (240 [59.6%]) and non-Hispanic ethnicity (253 [62.8%]). Among 407 infants, 367 (90.2%) were born full term and 212 (52.1%) were male. Overall, 258 infants (63.4%) had no documented prenatal exposure to SARS-CoV-2 infection, 112 (27.5%) had confirmed prenatal exposure, and 37 (9.1%) had exposure before pregnancy or at an indeterminate time. In adjusted models, maternal SARS-CoV-2 infection during pregnancy was not associated with differences in cognitive (β = 0.31; 95% CI, -2.97 to 3.58), gross motor (β = 0.82; 95% CI, -1.34 to 2.99), fine motor (β = 0.36; 95% CI, -0.74 to 1.47), expressive language (β = -1.00; 95% CI, -4.02 to 2.02), or receptive language (β = 0.45; 95% CI, -2.15 to 3.04) DAYC-2 subdomain scores. Trimester of exposure and maternal symptom status were not associated with DAYC-2 subdomain scores. CONCLUSIONS AND RELEVANCE: In this study, results of a novel telehealth-adapted observational neurodevelopmental assessment extended a previous finding of no association between prenatal exposure to maternal SARS-CoV-2 infection and infant neurodevelopment. Given the widespread and continued high prevalence of COVID-19, these data offer information that may be helpful for pregnant individuals who experience asymptomatic or mild SARS-CoV-2 infections. |

Suthar AB , Ouk V , Samreth S , Ngauv B , Bain R , Eng B , Hy C , Ernst A , Rutherford GW , Yang C , Ly V , Albalak R . J Infect Dis 2023 228 (10) 1347-1351 We compared characteristics of HIV diagnosis and recent HIV infection (i.e., likely acquired within the last year) in Cambodia. We included individuals ≥ 15 years old accessing HIV testing. From August/2020-August/2022, 53,031 people were tested for HIV, 6,868 were newly diagnosed, and 192 were recently infected. We found differences in geographical burden and risk behaviors with diagnosis and recency (e.g., men who have sex with men, transgender women, and entertainment workers had a nearly two-fold increased odds of testing recent compared to being diagnosed with HIV). Recent infection surveillance may provide unique insights into ongoing HIV acquisition to inform programs. |

Anyalechi GE , Bain R , Kindra G , Mogashoa M , Sogaula N , Mutiti A , Arpadi S , Rivadeneira E , Abrams EJ , Teasdale CA . J Trop Pediatr 2022 68 (6) BACKGROUND: We describe tuberculosis (TB) disease among antiretroviral treatment (ART) eligible children living with HIV (CLHIV) in South Africa to highlight TB prevention opportunities. METHODS: In our secondary analysis among 0- to 12-year-old ART-eligible CLHIV in five Eastern Cape Province health facilities from 2012 to 2015, prevalent TB occurred 90 days before or after enrollment; incident TB occurred >90 days after enrollment. Characteristics associated with TB were assessed using logistic and Cox proportional hazards regression with generalized estimating equations. RESULTS: Of 397 enrolled children, 114 (28.7%) had prevalent TB. Higher-income proxy [adjusted odds ratio (aOR) 1.8 [95% confidence interval (CI) 1.3-2.6] for the highest, 1.6 (95% CI 1.6-1.7) for intermediate]; CD4+ cell count <350 cells/µl [aOR 1.6 (95% CI 1.1-2.2)]; and malnutrition [aOR 1.6 (95% CI 1.1-2.6)] were associated with prevalent TB. Incident TB was 5.2 per 100 person-years and was associated with delayed ART initiation [hazard ratio (HR) 4.7 (95% CI 2.3-9.4)], malnutrition [HR 1.8 (95% CI 1.1-2.7)] and absence of cotrimoxazole [HR 2.3 (95% CI 1.0-4.9)]. Among 362 children with data, 8.6% received TB preventive treatment. CONCLUSIONS: Among these CLHIV, prevalent and incident TB were common. Early ART, cotrimoxazole and addressing malnutrition may prevent TB in these children. | BACKGROUND: We describe tuberculosis (TB) in children living with HIV (CLHIV) eligible for HIV treatment in South Africa to highlight opportunities to prevent TB. METHODS: We analyzed additional data from our original study of CLHIV who were 0–12 years old and due to start HIV treatment in five health facilities in Eastern Cape Province from 2012 to 2015 and assessed characteristics associated with existing and new TB. RESULTS: Of 397 enrolled children, 114 (28.7%) had existing TB. Children with a higher measure of household income had higher odds of existing TB. CD4+ cell count <350 cells/µl and malnutrition were also associated with existing TB. There were 5.2 new cases of TB for every 100 child-years. New TB was 4.7 times more likely for children with delayed HIV treatment start, 1.8 times more likely for children with malnutrition and 2.3 times more likely for children who did not get cotrimoxazole. Among 362 children with data, 8.6% received treatment to prevent TB. CONCLUSIONS: Among these CLHIV, existing and new TB were common. Early HIV treatment, cotrimoxazole and addressing malnutrition may prevent TB in these children. | eng |

Doshi RH , Apodaca K , Ogwal M , Bain R , Amene E , Kiyingi H , Aluzimbi G , Musinguzi G , Serwadda D , McIntyre AF , Hladik W . JMIR Public Health Surveill 2019 5 (3) e12118 BACKGROUND: Key populations, including people who inject drugs (PWID), men who have sex with men (MSM), and female sex workers (FSW), are disproportionately affected by the HIV epidemic. Understanding the magnitude of, and informing the public health response to, the HIV epidemic among these populations requires accurate size estimates. However, low social visibility poses challenges to these efforts. OBJECTIVE: The objective of this study was to derive population size estimates of PWID, MSM, and FSW in Kampala using capture-recapture. METHODS: Between June and October 2017, unique objects were distributed to the PWID, MSM, and FSW populations in Kampala. PWID, MSM, and FSW were each sampled during 3 independent captures; unique objects were offered in captures 1 and 2. PWID, MSM, and FSW sampled during captures 2 and 3 were asked if they had received either or both of the distributed objects. All captures were completed 1 week apart. The numbers of PWID, MSM, and FSW receiving one or both objects were determined. Population size estimates were derived using the Lincoln-Petersen method for 2-source capture-recapture (PWID) and Bayesian nonparametric latent-class model for 3-source capture-recapture (MSM and FSW). RESULTS: We sampled 467 PWID in capture 1 and 450 in capture 2; a total of 54 PWID were captured in both. We sampled 542, 574, and 598 MSM in captures 1, 2, and 3, respectively. There were 70 recaptures between captures 1 and 2, 103 recaptures between captures 2 and 3, and 155 recaptures between captures 1 and 3. There were 57 MSM captured in all 3 captures. We sampled 962, 965, and 1417 FSW in captures 1, 2, and 3, respectively. There were 316 recaptures between captures 1 and 2, 214 recaptures between captures 2 and 3, and 235 recaptures between captures 1 and 3. There were 109 FSW captured in all 3 rounds. The estimated number of PWID was 3892 (3090-5126), the estimated number of MSM was 14,019 (95% credible interval (CI) 4995-40,949), and the estimated number of FSW was 8848 (95% CI 6337-17,470). CONCLUSIONS: Our population size estimates for PWID, MSM, and FSW in Kampala provide critical population denominator data to inform HIV prevention and treatment programs. The 3-source capture-recapture is a feasible method to advance key population size estimation. |

Ong KS , Kinnett K , Soelaeman R , Webb L , Bain JS , Martin AS , Westfield C , Bolen J , Street N . Pediatrics 2018 142 S118-s128 Care Considerations for Duchenne Muscular Dystrophy were published in 2010. However, little is known about the extent to which these considerations were implemented after publication. With this article, we provide direction on evaluating the uptake of the 2018 Duchenne Muscular Dystrophy Care Considerations. We identify key elements of care and present suggestions for their use in evaluation and research. |
Shifting the HIV paradigm from care to cure: Proceedings from the Caribbean Expert Summit in Barbados, August 2017
Landis RC , Abayomi EA , Bain B , Greene E , Janossy G , Joseph P , Kerrigan D , McCoy JP , Nunez CA , O'Gorman M , Pastoors A , Parekh B , Quimby K , Quinn TC , Robertson K , Thomas R , van Gorp E , Vermund SH , Wilson V . AIDS Res Hum Retroviruses 2018 34 (7) 561-569 The CCAS EXPERT SUMMIT convened an array of international experts in Barbados on August 27-31 2017 under the theme "From Care to Cure - Shifting the HIV Paradigm". The Caribbean Cytometry & Analytical Society (CCAS) partnered with the Joint United Nations Programme on HIV/AIDS (UNAIDS) to deliver a program that reviewed the advances in antiretroviral therapy and the public health benefits accruing from treatment as prevention. Particular emphasis was placed on re-examining stigma and discrimination through a critical appraisal of whether public health messaging and advocacy had kept pace with the advances in medicine. Persistent fear of HIV driving discriminatory behavior was widely reported in different regions and sectors, including the healthcare profession itself; continued fear of the disease was starkly misaligned with the successes of new medical treatments and progress towards the UNAIDS 90:90:90 targets. The summit therefore adopted the mantra "Test:Treat:Defeat" to help engage with the public in a spirit of optimism aimed at creating a more conducive environment for persons to be tested and treated; and thereby help reduce HIV disease and stigma at the individual and community levels. |
Evaluation of automated molecular testing rollout for tuberculosis diagnosis using routinely collected surveillance data - Uganda, 2012-2015
Scott C , Walusimbi S , Kirenga B , Joloba M , Winters M , Abdunoor N , Bain R , Alexander H , Shinnick T , Toney S , Odeke R , Mwangi C , Birabwa E , Dejene S , Mugabe F , YaDiul M , Cavanaugh JS . MMWR Morb Mortal Wkly Rep 2017 66 (12) 339-342 In 2012, Uganda introduced the use of GeneXpert MTB/RIF (Cepheid, Sunnyvale CA), a sensitive, automated, real-time polymerase chain reaction-based platform for tuberculosis (TB) diagnosis, for programmatic use among children, adults with presumptive human immunodeficiency virus (HIV)-associated TB, and symptomatic persons at risk for rifampicin (RIF)-resistant TB. The effect of using the platform's Xpert MTB/RIF assay on TB care and control was assessed using routinely collected programmatic data; in addition, a retrospective review of district quarterly summaries using abstracted TB register data from purposively selected facilities in the capital city of Kampala was conducted. Case notification rates were calculated and nonparametric statistical methods were used for analysis. No statistically significant differences were observed in case notification rates before and after the Xpert MTB/RIF assay became available, although four of 10 districts demonstrated a statistically significant difference in bacteriologically confirmed TB. Once the GeneXpert MTB/RIF platform is established and refined, a more comprehensive evaluation should be conducted. |
