49. Effects of Maternal SARS-CoV-2 Infection on Neonatal Discharge Planning and Care: Exacerbation of Racial and Ethnic Healthcare Disparities

Background SARS-CoV-2 has exacerbated healthcare disparities. Maine’s population of 1.3 million is comprised of only 6% Black, Indigenous, People of Color (BIPOC); however, statewide 18% of SARS-CoV-2 infections have occurred in this group. This study examines newborn care inequities for infants born to mothers with SARS-CoV-2. Methods This study was conducted at Maine Medical Center in Portland, the largest hospital in Maine. Maternal SARS-CoV-2 infections from March 15, 2020 through April 1, 2021 were identified by PCR near time of delivery. Cases were matched to uninfected women by date of delivery. Chart review was conducted assessing demographic and clinical characteristics, comparing SARS-CoV-2 exposed and unexposed infants. The subset of SARS-CoV-2 exposed infants was further analyzed for trends in care by race. Protocol was exempt by MaineHealth IRB. Results Twenty four women and their infants were identified with maternal positive SARS-CoV-2 PCR just prior to delivery. An additional 24 unexposed infants were enrolled. When compared to unexposed infants, SARS-CoV-2 exposed were more likely to be racial minorities (63% vs 21%, p = 0.003), to have foreign-born mothers (58% vs 0.4%, p< 0.05) or to receive health care in a language other than English (29% vs 0.4%, p =0.02). For infants born to SARS-CoV-2 infected mothers, only 29% had initial follow up visit in person with their primary care provider (13% of BIPOC infants vs 56% of non-BIPOC infants, p = 0.03). Time to in-person follow up for exposed infants varied by race, with median time of 21 days (range 2-53 days) for racial minorities and 7.5 days (range 2-30 days) for non minorities. All families were discharged with a thermometer and scale for home management. No infants required re-admission during the month after discharge. One exposed infant tested positive for SARS-CoV-2. Conclusion The American Academy of Pediatrics recommends evaluation of newborns 3-5 days after discharge to identify maternal and child health factors affecting newborn well-being. The SARS-CoV-2 pandemic has made this challenging for patients, particularly for racial minorities. BIPOC pediatric patients were disproportionately affected by the pandemic in Maine, and were disproportionately affected by care discrepancies even when the infant was uninfected.

Neonatal Development in Prenatally Zika Virus-Exposed Infant Macaques with Dengue Immunity

Infants exposed to Zika virus (ZIKV) prenatally may develop birth defects, developmental deficits, or remain asymptomatic. It is unclear why some infants are more affected than others, although enhancement of maternal ZIKV infection via immunity to an antigenically similar virus, dengue virus (DENV), may play a role. We hypothesized that DENV immunity may worsen prenatal ZIKV infection and developmental deficits in offspring. We utilized a translational macaque model to examine how maternal DENV immunity influences ZIKV-exposed infant macaque neurodevelopment in the first month of life. We inoculated eight macaques with prior DENV infection with ZIKV, five macaques with ZIKV, and four macaques with saline. DENV/ZIKV-exposed infants had significantly worse visual orientation skills than ZIKV-exposed infants whose mothers were DENV-naive, with no differences in motor, sensory or state control development. ZIKV infection characteristics and pregnancy outcomes did not individually differ between dams with and without DENV immunity, but when multiple factors were combined in a multivariate model, maternal DENV immunity combined with ZIKV infection characteristics and pregnancy parameters predicted select developmental outcomes. We demonstrate that maternal DENV immunity exacerbates visual orientation and tracking deficits in ZIKV-exposed infant macaques, suggesting that human studies should evaluate how maternal DENV immunity impacts long-term neurodevelopment.

Outcomes of retained and disengaged pregnant women living with HIV in Uganda

Introduction Loss-to-follow-up among women living with HIV (WLWHIV) may lead to unfavorable outcomes for both mother and exposed infant. This study traced WLWHIV disengaged from care and their infants and compared their outcomes with those retained in care. Methods The study included WLWHIV who initiated ART during pregnancy at six public clinics in Uganda. A woman was defined as disengaged (DW) if she had not attended her 6-week post-partum visit by 10 weeks after her estimated date of delivery. DW were matched with retained women (RW) by age and duration on ART. Nurse counselors traced all selected DW via telephone and community visits to assess vital status, infant HIV sero-status and maternal HIV viral load through blood draws. Results Between July 2017 and July 2018, 734 women (359 DW and 375 RW) were identified for the study. Tracing was attempted on 349 DW and 160 (44.6%) were successfully located and enrolled in the study. They were matched with 162 RW. Among DW, 52 (32.5%) transferred to another health facility. Very few DW, 39.0% were HIV virally suppressed (<1000 copies/ml) compared to RW 89.5%, P<0.001). Among 138 babies born to DW, 4.3% tested positive for HIV compared to 1.4% among babies born to RW (P = 0.163). Conclusion Pregnant and breastfeeding WLWHIV who disengage from care are difficult to find in urban environments. Many have detectable viral loads, leading to the potential for an increased risk of MTCT. Efforts to reduce disengagement from care are critical for the successful elimination of MTCT in resource-limited settings.

Early-Life Exposure to the Chinese Great Famine and Later Cardiovascular Diseases

Objectives: This study aimed to examine the association between early life famine exposure and adulthood cardiovascular diseases (CVDs) risk.Methods: A total of 5,504 subjects were selected using their birthdate from national baseline data of the China Health and Retirement Longitudinal Survey to analyze the association between famine exposure in early life and CVDs risk in adulthood. CVDs was defined based on the self-reported doctor’s diagnosis.Results: The prevalence of CVDs in the unexposed group, fetal-exposed, infant-exposed, and preschool-exposed groups was 15.0%, 18.0%, 21.0%, and 18.3%, respectively. Compared with the unexposed group, fetal-exposed, infant-exposed and preschool-exposed groups had higher CVDs risk in adulthood (p &lt; 0.05). Compared with the age-matched control group, infancy exposed to famine had a significantly higher adulthood CVDs risk (OR = 1.52, 95% CI: 1.15, 2.01; p = 0.006). The association seems to be stronger among population with higher education level (Pinteraction = 0.043). Sensitivity analysis revealed consistent association between early-life famine exposure and adult CVDs risk.Conclusion: Early life exposed to the China great famine may elevate the risk of CVDs in adulthood.

Correlates of Health Care Workers’ Knowledge and HIV-Exposed Infant Immunization Counseling Practice in Northern Nigeria

Background: Human Immunodeficiency Virus (HIV)-exposed and HIV-infected infants are at increased risk of vaccine-preventable diseases. However, little is known about health care workers’ knowledge and immunization counseling practices in this population. We determined the predictors of health care workers’ knowledge of vertical transmission risks, HIV exposed/infected infant immunization, and counseling practices in a tertiary center in Northern Nigeria. Methods: A cross-section of 297 health workers were interviewed using a structured, validated questionnaire. Knowledge and HIV-exposed infant immunization counseling practices were analyzed, and adjusted odds ratios for predictors were derived from logistic regression models. Results: Of the 297 participating health care workers, (32.3%, n=96) had adequate knowledge of HIVexposed/infected infant immunization. Two-thirds (67%, n=199) of the participants appropriately identified the timing of infant diagnosis, while (73%, n=217) and (56.2%, n=167) correctly categorized infants as HIV-exposed and HIV-infected, respectively. Only (19.5%, n=58) participants had ever counselled a HIVpositive mother on infant immunization. Knowledge was predicted by work unit (HIV clinic vs. Obstetrics & Gynecology clinic), (Adjusted Odds Ratio (AOR) =3.78, 95% CI: 1.27-5.54), age (30-39 vs. <30 years), (AOR=2.24, 95% CI:1.19-5.67), years of experience (≥10 vs. <5), (AOR=1.76, 95% CI: 1.15-6.04), number of children (1 vs. 0), (AOR=1.73, 95% CI:1.14-4.23), infant immunization training (yes vs. no), (AOR=1.57, 95% CI:1.12-5.43), female sex (AOR = 1.17, 95% CI:1.06-2.21), profession (nurse/midwife vs. physician), (AOR=0.44, 95% CI:0.21-0.94) and previous HIV test (no vs. yes), (AOR=0.67, 95% CI:0.21-0.83). Conclusion and Global Health Implications: Knowledge of HIV-exposed infant immunization was low and counseling practices were sub-optimal. Both immunization knowledge and counseling practices were predicted by demographic, professional, and training variables. Our findings indicate the need for educating health care workers on HIV exposed/infected infant immunization policy and improving counseling skills through capacity-building programs.

Barriers to early infant diagnosis of HIV in the Wa Municipality and Lawra District of Upper West Region, Ghana

Objective: We identified socio-demographic, health system and psycho-social barriers to Early Infant Diagnosis (EID) of HIV in the Upper West Region of Ghana.Design: An unmatched case control study of 96 cases and 96 controls was conducted in the ART centers in Lawra district and Wa Municipality between December 2014 and April 2015.Setting: A public health facilityParticipants: We defined a case as an HIV positive mother with an exposed infant who received EID service between January 2011 and December 2014. A control was defined as HIV Positive Mother with an exposed infant who did not receive EID services between January 2011 and December 2014.Main outcome: EID by dry blood spot Deoxyribonucleic acid Polymerase chain reaction.Results: A total of 192 mother-infant pairs were assessed. The mean age of infants at testing for cases was 17.3±14.9 weeks. Mother-to-child-transmission-rate was 2.3%. Factors associated with EID testing included: mother being formallyemployed (cOR=2.0: 95%CI:1.1-3.8), maternal formal education (cOR=2.0, 95%CI: 1.1-3.6) and maternal independent source of income (cOR 2.2, 95%CI 1.2-4.1). After adjusting for confounders, maternal independent incomebsource was associated with EID testing (aOR 2.2, 95%CI 1.2-4.1). Median turn-around time of EID result was 11 weeks (IQR 4-27weeks).Conclusion: Women need to be empowered to gain an independent source of income. This can help maximize the benefits of e-MTCT and increase EID in the Upper West Region of Ghana.Keywords: Barriers; HIV; early infant diagnosis; DNA-PCR; GhanaFunding: This work was funded by the authors

Healthcare Workers’ Knowledge of HIV-Exposed Infant Feeding Options and Infant Feeding Counseling Practice in Northern Nigeria

Background: Despite the existence of evidence-based HIV-exposed infant feeding guidelines, infants in Africa still acquire HIV through inappropriate feeding practices. Objective: To identify predictors of HIV-exposed infant feeding knowledge and counseling practice among health care workers (HCW) in Nigeria. Methods: Structured, pretested questionnaires were administered to HCW (n=262) in a tertiary health facility in Kano, Nigeria. Multivariate logistic regression was used to determine predictors of HIV-exposed infant feeding knowledge and counseling practice. Results: Of 262 respondents, (58.0%, n=152) had good knowledge of recommended feeding options. Respondents listed exclusive breastfeeding (57.6%, n=151), human milk substitutes (45.4%, n=119), HIV-negative wet-nursing (37.0%, n=97), heated expressed human milk (20.6%, n=54) and mixed feeding (13.4%, n=35) as appropriate feeding choices. Over half (57.3%, n=150) of the respondents have ever counseled a HIV-positive mother on infant feeding. Knowledge was predicted by female sex (Adjusted Odds Ratio (AOR)=2.47, 95% Confidence Interval (CI):1.35-4.52), profession (physician vs. laboratory scientist, AOR=4.00, 95%CI:1.25-12.87; nurse/midwife vs. laboratory scientist, AOR=2.75, 95%CI:1.17-9.28), infant feeding counseling training (AOR=3.27, 95%CI:1.87-5.71), and number of children (2-4 vs. 0, AOR=1.75, 95%CI:1.23-3.92). Infant feeding counseling was predicted by female sex (AOR=2.85, 95%CI:1.39-5.85), age (>40 vs. <30 years, AOR=3.87, 95%CI:1.27-15.65), knowledge of infant feeding options (good vs. fair/poor, AOR=3.96, 95%CI:2.07-7.59), training (AOR=2.60, 95%CI:1.42-5.32), and profession (physician vs. laboratory scientist, AOR=10.7, 95%CI:2.85-40.54; nurse/midwife vs. laboratory scientist, AOR=4.8, 95%CI:1.26-18.02). Conclusion: The practice of infant feeding counseling among HCW in Nigeria is associated with sex, knowledge, and profession. Our findings may inform the development of targeted training programs for HCW in similar settings.
