Purpose: The purpose of this study was to compare birth outcomes between Korean women and immigrant women. Methods: Medical records were reviewed retrospectively from 201 immigrant women and 201 Korean women who delivered babies at K women's hospital in U city from January 2006 to December 2009. Maternal outcomes related factors included nationality, age, obstetric history, delivery type, indications of cesarean section, and complications of pregnancy and delivery. Principal neonatal outcomes were birth weight, Apgar scores, and complications of newborns. Results: Immigrant women were younger and had fewer pregnancies, abortions, and surviving children than Korean women. The rate of primary cesarean section and its indication in immigrant women were not significantly different from Korean women. However, immigrant women's newborn were more likely to have low birth weight and meconium staining. Conclusion: The results of this study indicate less equity of immigrant women in women's health care, although immigrant women's babies had lower Apgar score and more meconium staining. Nurses should help immigrant women cope with labor process effectively to prevent adverse health outcomes for their newborns.

Objective: This study examines whether maternal group B Streptococcus (Streptococcus agalactiae, GBS) infection was associated with preterm births and premature neonatal outcomes. Methods: Maternal and neonatal outcomes were examined among singleton pregnant women with preterm birth (from $24^{+0}weeks$ to $36^{+6}weeks$) who were tested for GBS (n=203) during the pregnancy. Data were collected retrospectively from the medical records of women who delivered at our hospital from January 2015 to February 2017. We compared obstetrical factors (causes of preterm birth) and neonatal (gestational age at delivery, birth weight, Apgar score 1 min/5 min, hospitalization period, duration of mechanical ventilation, neonatal C-reactive protein within three days, and other complication [respiratory distress syndrome, neonatal deaths]) outcomes between GBS-infected and non-infected pregnant women. Results: There were 203 singleton pregnant women included in the study, 25 of whom were confirmed to have a GBS infection during the pregnancy. There was no difference in neonatal outcomes by GBS status. Preterm premature rupture of membranes (pPROM), as an obstetric factor, was associated with GBS infection (P=0.022). GBS infection raised the risk of pPROM by 3.6 times (odds ratio 3.648, 95% confidence interval 1.476-9.016, P=0.005). Conclusion: GBS infection in preterm birth was associated with pPROM but did not result in adverse neonatal outcomes. Continuous attention and evaluation of GBS infection, a major cause of neonatal sepsis and pneumonia, are needed.

Objectives: Pregnant women are especially vulnerable to respiratory infections such as coronavirus disease 2019 (COVID-19), but insufficient research has investigated pregnancy and its outcomes in women with COVID-19. This cross-sectional study compared birth outcomes related to COVID-19 between Bangladeshi pregnant women with and without COVID-19. Methods: The study was conducted at 3 tertiary referral hospitals in Dhaka, Bangladesh, from March to August 2020. Pregnant women admitted for delivery at these hospitals with laboratory results (reverse-transcription polymerase chain reaction) were analyzed. Using convenience sampling, we included 70 COVID-19-positive and 140 COVID-19-negative pregnant women. Trained and experienced midwives conducted the interviews. Data were analyzed using the t-test, the chi-square test, and univariate and multivariable linear and logistic regression. Results: Pregnant women with COVID-19 were more likely to give birth to a preterm baby (adjusted odds ratio [aOR], 2.15; 95% confidence interval [CI], 1.06 to 4.37) and undergo a cesarean section (aOR, 3.27; 95% CI, 1.51 to 7.07). There were no significant differences in birth weight, premature rupture of membranes, and the Apgar score at 1 minute or 5 minutes post-delivery between women with and without COVID-19. All the newborn babies who were born to COVID-19-positive women were COVID-19-negative. Conclusions: Our study suggests that pregnant women with COVID-19 were more likely to give birth to a preterm baby and undergo a cesarean section. For this reason, physicians should be particularly cautious to minimize adverse birth outcomes among pregnant women with COVID-19 and their newborn babies.

Background: Antepartum, intrapartum, and postpartum preventive measures with antiretroviral drugs, appropriate delivery methods, and discouraging breastfeeding significantly decrease the risk of mother-to-child transmission of human immunodeficiency virus (HIV) infection. Herein, we investigated the pregnancy outcomes in HIV-infected Korean women. Methods: We retrospectively reviewed medical records of childbearing-age HIV-infected women between January 2005 and June 2017 at four tertiary care hospitals in Korea. Results: Among a total of 95 HIV infected women of child-bearing age with 587.61 years of follow-up duration, 15 HIV-infected women experienced 21 pregnancies and delivered 16 infants. The pregnancy rate was 3.57 per 100 patient-years. Among the 21 pregnancies, five ended with an induced abortion, and 16 with childbirth including two preterm deliveries at 24 and 35 weeks of gestation, respectively. The two preterm infants had low birth weight and one of them died 10 days after delivery due to respiratory failure. Among the 14 full-term infants, one infant was small for gestational age. There were no HIV-infected infants. Conclusion: The pregnancy rate of HIV-infected women in Korea is lower than that of the general population. Although several adverse pregnancy outcomes were observed, mother-to-child transmission of HIV infection was successfully prevented with effective preventive measures.

The purpose of the review article is to investigate the influence of periodontal diseases on preterm birth(PTB) and low birth weight(LBW). PTB and LBW are the main risk factors of infant mortality and a major public health problem. PTB is defined as delivery at less than 37 weeks and LBW is less than 2,500 grams. Over Approximately 60 percent of perinatal mortality results from PTB or LBW. Although the causes of PTB and LBW are not fully understood, infection is the leading cause of PTB and LBW. Periodontal diseases are serious disease burdens because they are caused by bacterial endotoxin, inflammatory reaction, and cytokine. The periodontal diseases are the predisposing factors of cerebrovascular and cardiovascular diseases including atherosclerosis. Over the past 15 years, previous studies revealed that periodontitis had adverse outcomes including PTB and LBW in pregnancy.

Implantation is a highly organized process that involves an interaction between a receptive uterus and a competent blastocyst. In humans, natural fecundity suggests that the chance of conception per cycle is relatively low (~30%) and two-third of lost pregnancies occur because of implantation failure. Defective implantation leads to adverse pregnancy outcomes including infertility, spontaneous miscarriage, intrauterine fetal growth restriction and preeclampsia. With use of advanced scientific technologies, gene expression analysis and genetically-engineered animal models have revealed critical cellular networks and molecular pathways. But, because of ethical restrictions and the lack of a mechanistic experiment, comprehensive steps in human implantation have still not been completely understood. This review primarily focuses on the recent advances in mechanisms of implantation. Because infertility is an emerging issue these days, gaining an understanding the molecular and hormonal signaling pathway will improve the outcome of natural pregnancy and assisted reproductive technology.
