Abstract
INTRODUCTION Vaccination is a key strategy to control the coronavirus disease 2019 (COVID-19) pandemic. Safety concerns strongly influence vaccine hesitancy. Disease transmission during pregnancy could exacerbate risks of preterm birth and perinatal mortality. This study examined patterns of vaccination and transmission among pregnant and postnatal women during the fifth wave of COVID-19 in Hong Kong. METHODS The Antenatal Record System and Clinical Management System of the Hospital Authority was used to retrieve information concerning the demographic characteristics, vaccination history, COVID-19 status, and obstetric outcomes of women who were booked for delivery at Queen Mary Hospital in Hong Kong and had attended the booking antenatal visit from 1 July 2021 to 30 June 2022. RESULTS Among 2396 women in the cohort, 2006 (83.7%), 1843 (76.9%), and 831 (34.7%) had received the first, second, and third doses of COVID-19 vaccine, respectively. Among 1012 women who had received the second dose, 684 (67.6%) women were overdue for their third dose. There were 265 (11.1%) reported COVID-19 cases. Women aged 20 to 29 years had a low vaccination rate but the highest disease rate (19.1%). The disease rate was more than tenfold higher in women who had no (20.3%) or incomplete (18.8%) vaccination, compared with women who had complete vaccination (2.1%; P<0.001). CONCLUSION Acceptance of COVID-19 vaccination was low in pregnant women. Urgent measures are needed to promote vaccination among pregnant women before the next wave of COVID-19.

Abstract
INTRODUCTION This study evaluated behavioural adaptations and responses to obstetric care among pregnant women during an early stage of the coronavirus disease 2019 (COVID-19) pandemic. METHODS This cross-sectional survey included pregnant women who received obstetric care from 27 May 2020 to 16 June 2020 in a university-affiliated hospital in Hong Kong. Responses were collected with respect to obstetric appointment scheduling, workplace changes, mask-wearing practices, travel and quarantine experiences, obstetric service adjustments, and visiting arrangements. Regression analysis was used to compare the effects of patient characteristics on their responses. RESULTS In total, 1000 surveys were distributed; 733 pregnant women provided complete survey responses. Among obstetric-related appointments in public hospitals, 16% were postponed or cancelled by pregnant women; such changes were most frequent among women beyond 24 weeks of gestation, women who had previous deliveries, and women who had a history of mental illness. The practice of working from home imposed psychological stress and negatively impacted the pregnancy experience in 4.5% of women. Childbirth companionship was regarded as an important service by 88.1% of women; only 4.2% agreed with its suspension. Obstetric service adjustments had the greatest impact on Chinese women and nulliparous women. CONCLUSIONS The findings provide an overview of how pregnant women adapted during an early stage of the COVID-19 pandemic. Women adjusted obstetric service attendance, began working from home, and wore masks. Women's expectations did not match changes in childbirth companionship and peripartum services. Hospital administrators should consider psychological impacts on pregnant women when implementing service adjustments.

Abstract
INTRODUCTION Owing to the coronavirus disease 2019 outbreak Hong Kong hospitals have suspended visiting periods and made mask wearing mandatory. In obstetrics, companionship during childbirth has been suspended and prenatal exercises, antenatal talks, hospital tours, and postnatal classes have been cancelled. The aim of the present study was to investigate the effects of these restrictive measures on delivery plans and risks of postpartum depression. METHODS We compared pregnancy data and the Edinburgh Postpartum Depression Scale (EPDS) scores of women who delivered between the pre-alert period (1 Jan 2019 to 4 Jan 2020) and post-alert period (5 Jan 2020 to 30 Apr 2020) in a tertiary university public hospital in Hong Kong. Screening for postpartum depression was performed routinely using the EPDS questionnaire 1 day and within 1 week after delivery. RESULTS There was a 13.1% reduction in the number of deliveries between 1 January and 30 April from 1144 in 2019 to 994 in 2020. The EPDS scores were available for 4357 out of 4531 deliveries (96.2%). A significantly higher proportion of women had EPDS scores of ≥10 1 day after delivery in the post-alert group than the pre-alert group (14.4% vs 11.9%; P<0.05). More women used pethidine (6.2% vs 4.6%) and fewer used a birthing ball (8.5% vs 12.4%) for pain relief during labour in the post-alert group. CONCLUSIONS Pregnant women reported more depressive symptoms in the postpartum period following the alert announcement regarding coronavirus infection in Hong Kong. This was coupled with a drop in the delivery rate at our public hospital. Suspension of childbirth companionship might have altered the methods of intrapartum pain relief and the overall pregnancy experience.

Abstract
OBJECTIVE The objective of the study is to evaluate the pattern and predictors of medical care received by hepatitis B virus (HBV) carriers during pregnancy and after delivery in Hong Kong. STUDY DESIGN The study is a retrospective analysis. METHODS Pregnant HBV carriers and their infants were followed up for 9-12 months after delivery. Face-to-face interviews were conducted to investigate what medical care they received for HBV before, during and after pregnancy. RESULTS Data were available for 412 HBV carriers. A total of 375 (91.0%) women were known HBV carriers before pregnancy. Routine antenatal screening picked out the remaining 37 (9.0%) HBV carriers; these women were younger, more likely to be smokers and had a lower level of education (P < 0.05) than known HBV carriers. In total, 356 of 412 (86.4%) HBV carriers did not receive any medical care for HBV during pregnancy. Known HBV carrier status, history of medical check-up and the use of antiviral treatment before pregnancy were significant predictors for HBV medical care during pregnancy (P < 0.05). The results show that 217 of 412 (52.6%) HBV carriers did not receive medical care for HBV after delivery. HBV medical care before pregnancy, use of antiviral treatment before pregnancy and a higher level of education were significant predictors for postpartum HBV medical care (P < 0.05). Multivariate analysis showed that HBV medical care before pregnancy (odds ratio [OR], 7.73; 95% confidence interval [CI], 3.21-18.65; P < 0.001) and the use of antiviral treatment (OR, 5.02; 95% CI, 1.41-17.81; P = 0.013) were associated with medical care during pregnancy. Medical care before pregnancy was also associated with postpartum HBV medical care (OR, 5.05; 95% CI, 3.29-7.51; P < 0.001). CONCLUSIONS A significant proportion of HBV carriers did not receive HBV-related medical check-ups during and after pregnancy in Hong Kong despite the majority being aware of their carrier status. Medical care before pregnancy predicted antenatal and postpartum HBV medical care.

Abstract
Hepatitis B infection remains the most common form of chronic hepatitis. Mother to child transmission occurs despite immunoprophylaxis with vaccination and immunoglobulin. In utero infection is suggested to account for most of the cases with immunoprophylaxis failure. Infants who suffer from hepatitis B infection at birth have a higher risk of becoming chronic carriers and may develop liver cirrhosis or hepatocellular carcinoma in the future. Infected germ cells, transplacental infection, invasive prenatal diagnostic tests and various perinatal factors are possible factors leading to in utero infection and subsequent immunoprophylaxis failure. Hepatitis B e antigen positive status and high viral load increase the risk of immunoprophylaxis failure. Recent evidence shows promising results regarding the use of antiviral treatment in late gestation to suppress viral load, so as to decrease the risk of vertical transmission. This review discusses the possible mechanisms of in utero infection and the use of antiviral treatment during pregnancy.
