A Maternity Waiting Home Is an Alternative Approach for the Accessibility of Pregnant Women in an Obstetrically Underserved Area of Korea

Background@#We analyzed whether a maternity waiting home (MWH) for pregnant women in an obstetrically underserved area of Gangwon-do in Korea, which has been in operation since August 2018, has improved the accessibility of a maternity hospital and pregnancy outcomes. @*Methods@#We compared and analyzed the accessibility of maternity hospitals for 170 pregnant women who applied for the MWH from August 2018 to May 2022. Among the 170 participants, 64 were MWH users and 106 non-users. The effect on pregnancy outcomes between MWH users and non-users was analyzed in the 160 people who achieved a pregnancy outcome. @*Results@#Although the average distance and travel time from the pregnant women’s residence in the obstetrically underserved area to a maternity hospital were 56.4 ± 1.6 km and 63.4 ± 1.4 minutes, respectively, the average distance between the MWH and the MWH users’ maternity hospital was 2.7 ± 0.2 km, and the travel time was 10.7 ± 0.6 minutes. The distance was 55.6 km closer on average and the travel time 54.1 minutes shorter. MWH users gave birth at a significantly later gestation age (38.9 ± 0.2 vs. 38.3 ± 0.15 weeks, P = 0.024) and to infants with heavier birth weights (3,300 ± 60 vs. 3,100 ± 50 gm, P= 0.024) compared with non-users. The rate of Cesarean section was significantly higher in the MWH users (47.5% vs. 44.6%, P = 0.047). The MWH users tended to be associated with a lower rate of neonatal intensive care unit admission (5.1% vs. 11.0%, P = 0.204), lower birth weight (< 2.5 kg) (1.7% vs. 8.0%, P = 0.155), and lower fetal death rate in the uterus (0% vs. 1.0%, P = 1.0) compared with non-users, but the differences were not significant. @*Conclusion@#The MWH helped pregnant women in obstetrically underserved areas by improving accessibility to a maternity hospital and lengthening gestation. As a result, neonatal birth weight was heavier for MWH users than non-users. MWHs in Korea can provide an alternative way to improve accessibility to maternity healthcare for pregnant women in obstetrically underserved areas, where it is difficult to establish maternity hospitals, and thereby will improve their pregnancy outcomes.

Current Treatment Guidelines and Antihypertensive Therapy of Mild Chronic Hypertension During Pregnancy

Up to 5% of pregnant females experience chronic hypertension, which is linked to poor pregnancy outcomes, and along with hemorrhage, is considered one of the main causes of maternal morbidity and mortality. The combined occurrence of preeclampsia, cesarean sections, preterm birth, birth weight less than 2,500 g, neonatal unit admission, and perinatal death was higher in females with chronic hypertension. Pregnancy with systolic blood pressure of 140-159 mmHg or diastolic blood pressure of 90-109 mmHg was considered to have mild-to-moderate chronic hypertension. Blood pressure management during pregnancy is a very important issue and is directly related to fetal growth and maternal health. Many studies have reported that antihypertensive therapy during pregnancy halves the incidence of severe hypertension in all types of hypertensive diseases. However, guidelines for optimal blood pressure management goals during pregnancy remain unclear. This is because the benefits to the mother from lowering blood pressure are uncertain, and there is a risk of fetal disorders due to the possibility of reduced uteroplacental blood flow. In light of a recently released CHAP (Chronic Hypertension and Pregnancy) randomized controlled trial, the purpose of this review was to provide a summary of the current recommendations for pregnant females with mild-to-moderate chronic hypertension.

Can an Increase in Delivery Medical Fees Prevent the Collapse of the Maternity Infrastructure System?

In an era of low fertility, the maternity infrastructure system has collapsed steeply and the number of obstetrically underserved areas has increased. To improve the maternity infrastructure, the Yoon Suk Yeol administration has announced the introduction of an essential medical support policy centered on introducing an additional delivery medical fee. The core of the essential medical policy for labor and delivery is the addition of regional medical fees, safety policy additional fees, and infectious disease-controll policy additional fees to the existing labor and delivery medical fees. The government's delivery medical additional fees will vary according region, with 200% increase in metropolitan cities, 300% increase in nonmetropolitan cities, and an additional 100% increase in the event of an infectious disease outbreak. After analyzing the government's plan to support additional fees, it is estimated that the total delivery expenses will be increased by Korean won (KRW) 236,619,748,266, and KRW 485,872,173 per maternity hospital. Even though this support plan is expected to help maintain maternity hospitals, this plan has limitations in small maternity hospitals in metropolitan cities and maternity hospitals for high-risk pregnant women. This is because the government's support policy is based on the "medical payment system by action," which is less effective in rural maternity hospitals with fewer deliveries and in training hospitals that mainly treat high-risk pregnant women rather than simple deliveries. Additionally, given the expected decline in the number of births in the future, it is estimated that the total delivery medical fees will steadily decline, as will the income per maternity hospital. To maintain a sustainable maternity infrastructure, it is essential to introduce the medical fees for operating a maternity delivery room that can be maintained, the medical fees for high-risk pregnancies, and various salary and protection support policies for obstetricians and nurses in addition to delivery medical fees.

Current Status of the Delivery Rate within the Jurisdiction of Local Government in Korea

Purpose@#This study aimed to analyze the rate of delivery within the jurisdiction of local governments in Korea. @*Methods@#Information regarding the population, number of women of childbearing age, and number of births was extracted from the Korean Statistics Information Service, National Health Insurance Service, and health map of the National Medical Center. We defined the rate of delivery within the jurisdiction of the local government as the ratio of the number of deliveries delivered by maternity facilities in the region to the total number of deliveries of pregnant women living in the region. @*Results@#The average nationwide delivery rate in the jurisdiction of local governments was 48.0%. The Si area was the highest at 54.9%, and the Gun area was the lowest at 22.1%. Compared to 2014, the national average delivery rate in the jurisdiction decreased by 4.3%; however, the gun area increased by 4.9%. The geographic maternity service area was 122 in 2014; however, this number decreased to 104 in 2020. @*Conclusion@#The national average rate of delivery in the jurisdiction of local governments was 48.0%, and the rate decreased between 2014 and 2020.

Limitation and Improvement Plan of Maternity Healthcare Delivery System in Korea

The Korean healthcare delivery system has been operating for over 30 years since 1989. Despite a positive performance—providing quality medical services to the people by distributing medical resources—there are limitations to the maternity healthcare delivery system. If the maternity healthcare delivery system was operating successfully, there should have been sufficient delivery hospitals so that pregnant women can access the appropriate maternity medical services whenever needed. Unfortunately, according to the National Health Insurance Service, the number of maternity health facilities in Korea reduced from 1,371 in 2003 to 541 in 2019. Regrettably, a larger number of obstetric hospitals and clinics have closed in medically vulnerable areas, such as farming and fishing areas, than urban areas with sufficient medical infrastructure, creating obstetrically underserved areas. In 2020, 65 out of a total of 250 cities, counties, and districts had no obstetric hospitals or clinics. To improve the collapsing maternity healthcare delivery system, a different approach is required; one in which policy support to stop the closure of delivery hospitals is emphasized. New maternity-related medical insurance payments, such as delivery labor management fees, fetal heart monitoring reading fees, and newborn care in delivery rooms fees, and active support policies are needed to prevent the closure of delivery hospitals. In this era of low fertility, because the maternity healthcare system is essential to maintain the nation, a healthcare delivery system different from the existing one must be established.

After 20 years of low fertility, where are the obstetrician-gynecologists?

Korea has entered a stage of low fertility, with a total fertility rate of 1.178 in 2002 and 0.92 in 2019. The low birth rate has led to the closure of obstetric hospitals and clinics from 1,371 maternity health facilities in 2003 to 541 in 2019, which is 39.5% compared to 2003. Since 2011, the Ministry of Health and Welfare has been operating an “Obstetrically Underserved Areas Support Project,” however, a shortage of obstetrician-gynecologists (OB/GYNs) who can participate in labor and delivery is a major problem. In 2019, there were 5,800 OB/GYNs practicing. Of these, 4,225 (72.8%) were working in obstetrics-gynecology hospitals, each responsible for 2,855 fertile women. Their average age was 51.8 years. A total of 2,659 (45.9%) worked in clinics and 3,110 (73.6%) were working in metropolitan districts. Only 124 OB/GYNs (2.9%) worked in vulnerable rural areas. OB/GYNs working in obstetric hospitals were responsible for 113.8 newborns in 2019. Their average age was 50.1 years. Of them, 67.4% were working in hospitals, 74.1% in urban areas, and only 60 specialists (2.3%) were working in rural areas. To establish a safe childbirth environment during an era of low fertility, it is important to have obstetricians in charge of childbirth. The government should establish a comprehensive long-term plan to resolve the shortage of OB/GYNs.

Clinical Practice Patterns of Hypertensive Disease in Pregnancy among Korean Obstetricians

Purpose@#The purpose of this study was to investigate the clinical practice patterns of Korean obstetricians and gynecologists the diagnosis and management of hypertensive disease in pregnant women. @*Methods@#From April 2015 to October 2015, questionnaire was distributed via email to obstetricians who were members of the Society for Maternal and Fetal Medicine. The survey consisted of 37 questions in 6 categories. Responses to the questions on the management of hypertensive disorders of pregnancy, from diagnosis to treatment, were evaluated. @*Results@#A total of 93 obstetricians and gynecologists responded to the survey. High blood pressure was allocated the highest priority as an index mainly used when deciding to hospitalize patients with hypertensive disease during pregnancy, followed by pregnancy symptoms, proteinuria, and blood test results. Calcium channel blocker (CCB) for oral administration and hydralazine for injection were preferred as antihypertensive drugs mainly used to control severe hypertension. Regarding the delivery method for hypertensive disease during pregnancy, in cases of preeclampsia, 63% of the respondents chose the delivery method according to the cervical status, and in cases of hemolysis, elevated liver enzymes and low platelets (HELLP) syndrome and eclampsia, which increased in severity, 52% and 31% responded that the delivery method was determined according to the cervical status, respectively. In cases of mild preeclampsia, the 70% of respondents preferred 37–38 weeks of gestation for the delivery time. Regarding the use of aspirin in patient with hypertension during pregnancy, 52% of the respondents occasionally administered aspirin, and in patients with a history of hypertensive disease during pregnancy, only 43% were administered prophylactic aspirin. @*Conclusion@#Domestic obstetricians regarded blood pressure as the most meaningful factor when treating women with hypertension during pregnancy and considered blood pressure control as important. The preferred antihypertensive agents were oral CCB and hydralazine injections, and the choice of delivery method was determined according to the condition of the cervix and severity of the disease. Even in women with high risk factors for preeclampsia, prophylactic aspirin was administered in as low as 50%, of patients, possibly may due to the absence of domestic guidelines for aspirin use during pregnancy. Korean guidelines for prophylactic aspirin administration during pregnancy is needed based on additional research on the efficacy of aspirin for domestic women in the future.

Serum Ferritin Concentration in the Early Third Trimester of Pregnancy and Risk of Preterm Birth and Low Birth Weight Based on Gestational Age

Objective@#Although serum ferritin is considered the best measure of total body iron, with low levels indicating iron deficiency, recent studies have shown that high levels are associated with gestational diabetes, premature birth, and low birth weight. This study aimed to analyze the association between serum ferritin levels in the third trimester of pregnancy and low birth weight and preterm birth. @*Methods@#This study included pregnant women who delivered a single fetus at Kangwon National University Hospital between January 2009 and December 2013 and in whom serum ferritin levels were measured between 28 and 34 weeks of gestation. The association between serum ferritin levels measured in the early third trimester of pregnancy and preterm birth and low birth weight infants was analyzed. @*Results@#A total of 1,079 women fulfilled the study criteria and had their serum ferritin level measured during the third trimester (28–33.9 weeks of gestation) and later delivered at Kangwon National University Hospital. Comparison of the group with serum ferritin levels above the 75th percentile and those below the 25th percentile at the beginning of the third trimester revealed that the incidence of preterm births (<34 weeks of gestation, <37 weeks of gestation) and low birth weight were significantly higher in the group with serum ferritin levels above the 75th percentile than those below the 25th percentile (p<0.05). When variable factors were controlled through multiple regression analysis, the group whose serum ferritin levels were above the 75th percentile at 30–31.9 weeks of gestation had the highest risk of preterm birth before 34 weeks of gestation (adjusted odds ratio [OR], 7.85; 95% confidence interval [CI], 1.32–29.9) and low birth weight (adjusted OR, 6.49; 95% CI, 2.10–20.0). @*Conclusion@#In this study, when serum ferritin was high in the third trimester of pregnancy, it was significantly increased with preterm birth (<34 and 37 weeks) and low birth weight. In particular, when serum ferritin levels were high at 30–31.9 weeks of gestation, the risk of premature birth before 34 weeks and low birth weight was statistically highest.

Recent Advances in Uterine Myoma and Pregnancy

Uterine myomas (fibroids) are the most common benign tumors in women and occur in 20%–40% of women of reproductive age. Myomas are benign monoclonal tumors that develop from the smooth muscle cells of the myometrium. Most pregnant women with myomas do not have complications during pregnancy, but complications can occur. Among the complications, pain is the most common, and the risks of miscarriage, preterm labor and delivery, abnormal positioning of the fetus, and placental abruption increase slightly. There are also concerns about the potential effects of uterine myomas on infertility and reproductive function. Therefore, there are frequent clinical concerns about the presence of myomas during pregnancy;however, the treatments are unclear. In this study, we summarize the latest trends in uterine myomas and pregnancy and consider the treatments.

Reclassification of High-Risk Pregnancy for Maternal-Fetal Healthcare Providers

High-risk pregnancy is the probability of adverse pregnancy out come is increased over the generalpregnant population. Some high-risk pregnancy is the result of a medical condition present beforepregnancy. In other cases, a medical condition that develops during pregnancy causes a pregnancy tobecome high risk. The reason why high-risk pregnancy is importa nt is detecting the risk factors forhigh risk pregnancy early and preventing the complicated pregnancy. Korean society of Obstetrics andGynecology (KSOG) announced the classification of high-risk pre gnancy including 95 risk factors:obstetrics risk factors, medical risk factors, physical risk factors and risk factors of current pregnancy.However, this announcement of high-risk pregnancy by KSOG was limited for maternal-fetal healthcareproviders to apply their working and making policy. First this didn't include the conception of thecomplicated pregnancy and high-risk delivery. Second this did not separate the risk factors depend onbefore and during pregnancy. This review briefly evaluates the classification of high-risk pregnancy byKSOG and suggest the new classification including the complicated pregnancy and high-risk delivery formaternal-fetal healthcare providers.

Renovation of Maternal-child Healthcare Centers and the National Maternal-child Medical Center Based on the Mother and Child Act

The Mother and Child Act is the most important law set up to maintain and improve maternal-child healthcare. This act was established in 1973 and was revised to improve maternal-child healthcare. This act includes the establishment and management of a maternal-child healthcare center in the district, a maternal-child regional healthcare center in the province, and a national maternal-child medical center. In the baby boom era, maternal-child healthcare centers provided maternity care and delivery services as well as emergency obstetrical management, but those centers stopped providing maternity care in the low birth-rate era. The last revised act included the establishment of a national maternal-child medical center to care for the increase in the number of high-risk pregnancies. This review briefly evaluates the goals and roles of a maternal-child healthcare center and a national maternal-child medical center according to the Mother and Child Act, and integrates high risk pregnancies with a neonatal care center to renovate the maternity healthcare system.

The Current State of Maternity Care and Suggestions for Improvement in the Management of High-risk Pregnancies in South Korea

Since the year 2000, low birth rates have resulted in significant decreases to maternity care services throughout many Korean hospitals. However, there has been a concomitant increase in the number of high-risk pregnancies, due to growing trends in delayed marriages and subsequent pregnancies. Increased maternal age is a risk factor associated with complicated pregnancies and high-risk deliveries, both of which are strongly related to maternal death. With this in mind, the Ministry of Health and Welfare has supported the establishment of a regional perinatal center for high-risk pregnancies, estimated to be be fully completed by the year 2020. Despite this, maternity care services for high-risk pregnancies remain insufficient. According to previous reports, the total number of maternity care hospitals and beds available for high-risk pregnant women were 60 and 399, respectively. This is in stark contrast to previous bed estimates of 1,640. The establishment of a maternity care system for high-risk pregnant women is integral to ensuring optimal conditions for both pregnancy and childbirth. This review briefly evaluates the existing maternity care system for high-risk pregnancies, and proposes several new suggestions for improvements.

Secure Plan of Appropriate Obstetricians and Nurses for Safe Childbirth in Korea

Because childbirth is a complex and difficult process, intensive preparation, and the immediate availability of emergency assistance during every step of delivery support to maternal safety. The World Health Organization recommends that pregnant women must be able to access the right care at the right time. Appropriate obstetricians is important factor for easy access during pregnancy. Especially, an increase in the number of specialists in maternal-fetal medicine would greatly improve the pregnancy outcomes of high-risk women. In 2013, a total of 2,274 obstetricians were employed in maternity hospitals and clinics in Korea. Their average age was 44.8 years and they will get older soon. By 2026, 740 junior obstetricians will join the maternity care system, but 916 senior obstetricians will have retired on night duty at hospital because of above 60 years of age. Thus, obstetrician numbers will fall by 176. Korea requires 2,338~3,507 obstetricians based on an annual number of deliveries per obstetrician in 2016. However, Korea has a shortage of obstetricians because of the low birth rate-induced business losses, inadequate payment system by the national health insurance program, and the quality-of-life preferences of young doctors. Ensuring an appropriate supply of obstetricians is essential for infrastructure of safe childbirth. I believe that adequate payment by the national health insurance program, and new medical insurance fees for management of high-risk pregnancies, will encourage young doctors to become obstetricians. The government should also introduce additional night duty fees and overseas training programs for young obstetricians.

Carbon monoxide prevents TNF-α-induced eNOS downregulation by inhibiting NF-κB-responsive miR-155-5p biogenesis

Heme oxygenase-1-derived carbon monoxide prevents inflammatory vascular disorders. To date, there is no clear evidence that HO-1/CO prevents endothelial dysfunction associated with the downregulation of endothelial NO synthesis in human endothelial cells stimulated with TNF-α. Here, we found that the CO-releasing compound CORM-2 prevented TNF-α-mediated decreases in eNOS expression and NO/cGMP production, without affecting eNOS promoter activity, by maintaining the functional activity of the eNOS mRNA 3′-untranslated region. By contrast, CORM-2 inhibited MIR155HG expression and miR-155-5p biogenesis in TNF-α-stimulated endothelial cells, resulting in recovery of the 3′-UTR activity of eNOS mRNA, a target of miR-155-5p. The beneficial effect of CORM-2 was blocked by an NF-κB inhibitor, a miR-155-5p mimic, a HO-1 inhibitor and siRNA against HO-1, indicating that CO rescues TNF-α-induced eNOS downregulation through NF-κB-responsive miR-155-5p expression via HO-1 induction; similar protective effects of ectopic HO-1 expression and bilirubin were observed in endothelial cells treated with TNF-α. Moreover, heme degradation products, except iron and N-acetylcysteine prevented H₂O₂-mediated miR-155-5p biogenesis and eNOS downregulation. These data demonstrate that CO prevents TNF-α-mediated eNOS downregulation by inhibiting redox-sensitive miR-155-5p biogenesis through a positive forward circuit between CO and HO-1 induction. This circuit may play an important preventive role in inflammatory endothelial dysfunction associated with human vascular diseases.

Serum from pregnant women with gestational diabetes mellitus increases the expression of FABP4 mRNA in primary subcutaneous human pre-adipocytes

OBJECTIVE: Gestational diabetes mellitus (GDM) is defined as glucose intolerance first detected during pregnancy. It can result in pregnancy complications such as birth injury, stillbirth. Fatty acid-binding protein 4 (FABP4), found in adipose tissue, is associated with insulin resistance, and type 2 diabetes. The aim of this study was to investigate whether FABP4 in the placenta and decidua of pregnant women with GDM is higher than that in normal pregnant women, and whether serum from pregnant women with GDM may cause adipocytes to secrete more FABP4 than does serum from a normal pregnant group. METHODS: We obtained placentas, deciduas, and serum from 12 pregnant women with GDM and 12 normal pregnant women and performed enzyme-linked immunosorbent assay, real time quantitative-polymerase chain reaction. We cultured human pre-adipocytes for 17 days with GDM and non-GDM serum and performed western blot, real time quantitative-polymerase chain reaction, and oil red O staining. RESULTS: Expression of FABP4 in serum, placenta and decidua of pregnant women with GDM was significantly higher than that in normal pregnant women. Serum from pregnant women with GDM increased the expression of FABP4 mRNA and decreased the expression of adiponectin mRNA in human pre-adipocytes significantly. Adipocyte cultured in GDM serum showed significantly greater lipid accumulation than those cultured in normal serum. CONCLUSION: Our results suggest that FABP4 is higher in placenta and decidua from pregnant women with GDM. Increased circulating FABP4 in maternal serum from pregnant women with GDM may originate from adipocytes and the placenta. Circulating FABP4 can induce increased insulin resistance and decreased insulin sensitivity.

Maternity care system for high risk pregnant women in obstetrically underserved area

The number of maternity care hospitals in underserved areas has been falling since 2004 because of business losses steming from low birth rates, inadequate insurance payments for obstetric services, and the shortage of obstetricians. However, the proportion of pregnant women at high risk in Korea has been increasing for decades because of the delay of marriage and the greater number of older pregnant women. High-risk pregnancies tend to lead to pregnancy complications and are associated with high-risk deliveries. An insufficient maternity care system for highrisk pregnant women in Korea has resulted in an increase in maternal mortality. The Ministry of Health and Welfare has supported the establishment of maternity care centers in underserved areas and regional perinatal centers to reduce maternal mortality. Even though the regional perinatal centers are a good system for reducing maternal mortality, they are limited in scope, in that they are not being established quickly on a nationwide scale to detect high-risk pregnancies earlier. This review briefly describes the current maternity care system for high-risk pregnancies and proposes a direction for the development of a health care delivery system between the regional perinatal centers and the maternity care system in underserved areas.

Prenatal diagnosis of large subamniotic cyst compressing the umbilical cord on umbilicoplacental junction : A case report / 대한산부인과학회지

Placenta surface cyst classified subamniotic hematoma, subchorionic hematoma and subchorionic cyst by histological finding. These cysts did not affect the obstetrical outcome according to the previous report. However, we experienced that the subamniotic cyst compressed the umbilical cord to result in fetal deceleration. We report this case with brief review of literature.
