Abstract
SARS-Cov2 infection has recently spread to Italy with important consequences on pregnancy management, mother and child health and mother-child contact. Breastfeeding improves the health of mother and child and reduces risk of neonatal infection with other pathogens that are likely to cause serious illness. To date no evidence confirmed COVID-19 vertical transmission from infected pregnant mother to their fetus. However it is well known that an infected mother can transmit the COVID-19 virus through respiratory droplets during breastfeeding or intimate contact. Thus, the mothers with known or suspected COVID-19 should adhere to standard and contact precautions during breastfeeding. Woman Study Group of AMD, after reviewing current knowledge about COVID-19 vertical transmission and the compatibility of breastfeeding in COVID-19 mother, the available recommendations from Health Care Organizations and main experts opinions, issued the following suggestions on breastfeeding during the COVID-19 pandemic, addressed both to mothers with and without diabetes. It should be considered that following suggestions may change in the future when more evidence is acquired regarding SARS-Cov2 infection.

Abstract
BACKGROUND & AIMS Tenofovir disoproxil fumarate (TDF) is the preferred treatment to prevent maternal transmission of HBV, owing to its efficacy and safety. However, data are lacking on the long-term safety outcomes in children following fetal exposure to TDF. METHODS Children participating in a prospective, multisite trial of maternal TDF treatment during late pregnancy were recruited for follow-up visits once a year. Growth parameters, serum biochemistry, HBV serology, and bone mineral density (BMD) by dual-energy x-ray absorptiometery scan were measured. RESULTS One hundred and twenty-eight children, 71 in the TDF and 57 in the control group, completed 255 follow-up visits at the age of 2 to 7 (median, 4.08) years. No differences in z-scores for weight-for-age (0.26 ± 0.90 vs. 0.22 ± 0.99, p = 0.481), z-scores for height-for-age (0.20 ± 1.02 vs. 0.25 ± 0.98, p = 0.812), and estimated glomerular filtration rate (169.12 ± 50.48 vs. 169.06 ± 34.46 ml/min/1.73m2, p = 0.479) were detected. After adjustment for age, sex and HBV status by multiple linear regression, children in the TDF and control group had comparable levels of serum calcium, phosphorus, bone-specific alkaline phosphatase, calcidiol and BMD of lumbar spines (0.55 ± 0.01 vs. 0.57 ± 0.01 g/cm2, p = 0.159) and left hip (0.56 ± 0.01 vs. 0.56 ± 0.01 g/cm2, p = 0.926). CONCLUSIONS Children of HBV-infected mothers who did or did not receive tenofovir disoproxil fumarate treatment during late pregnancy had comparable long-term growth, renal function, and bone development up to 6-7 years after delivery. CLINICAL TRIAL NUMBER NCT01312012 (ClinicalTrials.gov) LAY SUMMARY Currently there are insufficient long-term safety data in children born to mothers who took antiviral agents during pregnancy to prevent mother-to-infant transmission of hepatitis B virus (HBV). In this study, we found that children of HBV-infected mothers who did or did not receive tenofovir disoproxil fumarate treatment during late pregnancy had comparable long-term growth, renal function, and bone development up to 6-7 years after delivery.

Abstract
INTRODUCTION Following the implementation of the provision of lifelong antiretroviral therapy to all HIV-positive pregnant or breastfeeding women for prevention of mother-to-child transmission (PMTCT) of HIV by the Kingdom of Lesotho in 2013, we assessed the effectiveness of this approach by evaluating 24-month HIV-free survival among HIV-exposed infants (HEIs). METHODS We conducted a prospective observational cohort study that enrolled HIV-positive and HIV-negative pregnant women, with follow-up of women and their infants for 24 months after delivery. Participant recruitment started in June 2014 and follow-up ended in September 2018. Trained nurses collected study information through patient interviews and chart abstraction at enrolment and every three to six months thereafter. Maternal HIV testing, infant mortality, HIV transmission and HIV-free survival rates were computed using Kaplan-Meier estimation. Cox regression hazard models were used to identify factors associated with infant HIV infection and death. RESULTS Between June 2014 and February 2016, we enrolled 653 HIV-positive and 941 HIV-negative pregnant women. Twenty-seven HIV-negative women acquired HIV during follow-up. Ultimately, 634 liveborn HEI (382 (52%) male, 303 (48%) female, 3 missing) and 839 who remained HIV-unexposed (HUIs) (409 (49.0%) male, 426 (51.0%) female, 4 missing) were followed; 550 HEIs and 701 HUIs completed the 24-month follow-up period. Of 607 (95.7%) HEIs who were tested for HIV at least once during follow-up, 17 were found to be HIV-positive. Two (9.5%) of 21 infants born to mothers who acquired HIV infection during follow-up were HIV-positive compared to 15 (2.4%) of 613 HEI born to women with known HIV infection. The risk of HIV transmission from HIV-positive mothers to their infants by 24 months of age was 2.9% (95% CI: 1.8 to 4.7). The estimated 24-month mortality rate among HEIs was 6.0% (95% CI: 4.4 to 8.2) compared to 3.8% (95% CI: 2.6 to 5.3) among HUIs (Log-rank p = 0.065). HIV-free survival at 24 months was 91.8% (95% CI: 89.2 to 93.7). Lower maternal age and birth weight were independently associated with increased HIV infection or death of infants. CONCLUSIONS The implementation of lifelong ART for PMTCT in the Lesotho public health system resulted in low HIV transmission, but survival of HEI remains lower than their HIV uninfected counterparts.

Hepatology international. 2020;(3):338-346
Abstract
BACKGROUND Hepatitis B is a serious global health problem. Mother-to-child transmission (MTCT) of hepatitis B virus (HBV) is a major risk factor in the endemicity of HBV infection. Oral antiviral drugs are recommended to highly viremic mothers to decrease MTCT of HBV. The present network analysis compared the efficacy of available treatments to prevent the MTCT of HBV. METHODS The electronic databases of PubMed, Embase, Web of Science, Scopus, and Wanfang data were searched for eligible studies. Pair-wise meta-analysis and Bayesian network analysis were applied to compare the efficacy of antiviral drugs. RESULTS Seventy-five studies involving 12,740 pregnant females were eligible for analysis. On pair-wise analysis, lamivudine (OR 0.15, 95% CI 0.09-0.25, I-squared = 0%), telbivudine (OR 0.07, 95% CI 0.05-0.10, I-squared = 0%) and tenofovir (OR 0.07, 95% CI 0.04-0.13, I-squared = 0%) significantly decreased the MTCT rate. Results of multiple comparisons with ranking probability based on Bayesian analysis showed that tenofovir (SUCRA = 96.83%) appeared more effective than the two other drugs. CONCLUSION In addition to active and passive immunoprophylaxis, lamivudine, telbivudine and tenofovir in highly viremic mothers can further decrease MTCT of HBV. Based on direct and indirect evidence, tenofovir appears to be more effective than the two other drugs in the prevention of HBV MTCT.

Abstract
The World Health Organization announced on 12 March 2020 a global pandemic of the new SARS-CoV-2 coronavirus causing COVID-19 disease associated with pneumonia and acute respiratory failure. SARS-CoV-2 has caused so far over 6.66 million recorded cases, of which 393,000 ended in death (as of June 1, 2020). Despite the demographic statistics of incidence, there is no current recording of cases in the group of pregnant or perinatal women. Changes occurring in the female body system during pregnancy also affect and alter the immune system, and as studies based on other viral respiratory infections have shown, the population of pregnant women is at risk of having a severe course of the disease. The aim of the study is to summarize current reports on the course of COVID-19 disease in a group of pregnant women and the possible impact of SARS-CoV-2 on the foetus and vertical transmission, taking into account changes occurring in the woman's immune system during pregnancy. Available advice and recommendations for antenatal and perinatal care of pregnant women during the pandemic period are also included.

Abstract
BACKGROUND Despite policies and guidelines recommending integration of health services in South Africa, provision of maternal and child health services remains fragmented. This study evaluated a rapid, scaleable, quality improvement (QI) intervention to improve integration of maternal and child health and HIV services at a primary health level, in KwaZulu-Natal, South Africa. METHODS A three-month intervention comprised of six QI mentoring visits, learning sessions with clinic staff to share learnings, and a self-administered checklist aimed to assist health workers monitor and implement an integrated package of health services for mothers and children. The study evaluated 27 clinics in four sub-districts using a stepped-wedge design. Each sub-district received the intervention sequentially in a randomly selected order. Five waves of data collection were conducted in all participating clinics between December 2016-February 2017. A multi-level, mixed effects logistic regression was used to account for random cluster fixed time and group effects using Stata V13.1. RESULTS Improvements in some growth monitoring indicators were achieved in intervention clinics compared to control clinics, including measuring the length of the baby (77% vs 63%; p = 0.001) and health workers asking mothers about the child's feeding (74% vs 67%; p = 0.003), but the proportion of mothers who received feeding advice remained unchanged (38% vs 35%; p = 0.48). Significantly more mothers in the intervention group were asked about their baby's health (44% vs 36%; p = 0.001), and completeness of record keeping improved (40% vs 26%; I = < 0.0001). Discussions with the mother about some maternal health services improved: significantly more mothers in the intervention group were asked about HIV (26.5% vs 19.5%; p = 0.009) and family planning (33.5% vs 19.5%; p < 0.001), but this did not result in additional services being provided to mothers at the clinic visit. CONCLUSION This robust evaluation shows significant improvements in coverage of some services, but the QI intervention was unable to achieve the substantial changes required to provide a comprehensive package of services to all mothers and children. We suggest the QI process be adapted to complex under-resourced health systems, building on the strengths of this approach, to provide workable health systems strengthening solutions for scalable implementation.

HIV Infection in Pregnant Women: A 2020 Update.
Harris, K, Yudin, MH
Prenatal diagnosis. 2020;(13):1715-1721
Abstract
Acquired immunodeficiency syndrome (AIDS) was first described in 1981, and continues to be one of the worst global health pandemics in recorded history. Concerted international efforts have helped to increase awareness of human immunodeficiency (HIV) status, improve access to treatment and continuation of therapy to achieve viral suppression with a goal of ending the AIDS epidemic by 2030. The clinical outcomes for patients living with HIV on combined antiretroviral therapy are considerably improved with prolonged life expectancy and superior quality of life. Further, perinatal transmission rates have dramatically decreased with elimination of mother to child transmission of HIV in a growing number of countries worldwide. However, there have been significant reductions in the pace of progress in treatment expansion for pregnant women with failure to meet global targets in 2018. In this review, we will highlight recent advances and challenges ahead in 2020 for three areas of perinatal care for women with HIV in developed countries: (a) pregnancy planning considerations, (b) impact of antiviral medications on perinatal outcomes, and (c) infant feeding practices. The promise of a HIV-free generation is on the horizon and continued international efforts in preventing perinatal transmission are an important component of this achievement.

Abstract
As the COVID-19 pandemic continues to spread worldwide, it is crucial that we determine populations that are at-risk and develop appropriate clinical care policies to protect them. While several respiratory illnesses are known to seriously impact pregnant women and newborns, preliminary data on the novel SARS-CoV-2 Coronavirus suggest that these groups are no more at-risk than the general population. Here, we review the available literature on newborns born to infected mothers and show that newborns of mothers with positive/suspected SARS-CoV-2 infection rarely acquire the disease or show adverse clinical outcomes. With this evidence in mind, it appears that strict postnatal care policies, including separating mothers and newborns, discouraging breastfeeding, and performing early bathing, may be more likely to adversely impact newborns than they are to reduce the low risk of maternal transmission of SARS-CoV-2 or the even lower risk of severe COVID-19 disease in otherwise healthy newborns.

Xiao, F, Lan, A, Mo, W
Minerva pediatrica. 2020;(2):109-115
Abstract
INTRODUCTION Previously meta-analysis had different conclusions about the role of breastfeeding in mother-to-child transmission (MTCT) of hepatitis B virus (HBV). We aimed to carry out an updated meta-analysis based on current published evidence to explore that whether breastfeeding increase the risk of HBV infection from mothers carrying HBV after proper immunoprophylaxis in the infants or not. EVIDENCE ACQUISITION Databases searched from January 1st,2000 to August 1st,2016 included PubMed searching engine, Cochrane Library, Embase database, Chinese National Knowledge Infrastructure, VIP Chinese database, and Wanfang Chinese database. EVIDENCE SYNTHESIS 17 studies were incorporated into our meta-analysis. Our result showed that there was no significant difference between the breastfeeding group and the non-breastfeeding group (ORs=1.01, 95%CI: 0.75-1.36, I2=0). Further, there was no significant difference between the cases and controls in HBVac group (ORs=1.08, 95%CI: 0.42-2.76, I2=0) and in HBIG combined with HBVac group (ORs=0.97, 95%CI: 0.68-1.37, I2=0). CONCLUSIONS Our update meta-analysis indicated that breastfeeding would not increase the risk of HBV injection from mothers carrying HBV after proper immunoprophylaxis in the infants. The results suggest that mother carrying HBV can breastfeed their babies after proper immunoprophylaxis in the infants.

Abstract
BACKGROUND The HIV perinatal transmission in India even after interventions is still high. The anti-retroviral therapy failure rate and the risk of HIV vertical transmission to infants from women with failed treatment during pregnancy also largely remains unevaluated. METHODS This is a prospective, observational and follow-up study of 18 months to determine the association of ART failure in pregnant women and the subsequent risk of HIV transmission to their infants. A total of 81 mothers were evaluated for ART success/failure by analysing their viral loads. RESULTS Analyses revealed that a high percentage (19.75%) of women on ART had high viral loads, while the overall HIV transmission rate to the infants was 8.64%. The rate of transmission from women with high viral load was significantly high compared to women with low viral load (37.5% vs. 1.54%; p = 0.0015). CD4 level was not associated with HIV transmission. However, CD4 levels in women, who had successful or failed ART, were significantly different (p = 0.0031). Factors such as mother's age, baby's sex and weight as well as delivery mode were not associated with HIV transmission, however, breastfeeding and viral loads were found to be independently associated with HIV transmission to the neonates. CONCLUSIONS This study highlights that a significant proportion of women on ART had impaired viral load control. The rate of HIV transmission to infants was also significantly high among these women. This warrants viral load monitoring of HIV infected women to reduce the overall transmission to the infants.
