OBJECTIVETo analysis the trend of maternal death time and explore the impact of the variety of death causes and birth place to maternal death time.

METHODSAccording to the data provided by Beijing Maternal and Children Health Hospital, the 372 death cases of pregnant and lying-in women from 1995 to 2010, a retrospective study was performed to analyze the death causes, maternal death time and the influencing factors.

RESULTSThe MMR declined from 27.9 per 100 000 live births from 1995 to 2000 to 14.8 per 100 000 live births from 2006 to 2010, with a decline of 46.9%. Among the maternal death within 24 hours of delivery, 79.7% (106/133) died of obstetric hemorrhage, hypertensive disorder complicating pregnancy and amniotic fluid embolism. It took up 47.8% (64/134) from 1995 to 2000, reduced to 37.5% (45/120) from 2006 to 2010. At the same time, the maternal mortality ratio within 24 hours reduced from 40.2%(54/134) to 28.3% (34/120), the variation of death time was consistent with the causes of maternal mortality (χ² = 59.109, P < 0.05). Indirect obstetric causes increased significantly from 2006 to 2010, 53.2% (33/62) of pregnant women with heart disease, cerebrovascular disease and pulmonary embolism died in prenatal or more than 120 hours postnatal. Among the maternal death delved in hospital, 29.0% (29/100) died within 24 hours, 52 cases delved at home or in private clinics, 43 cases (82.6%) died within 24 h postnatal. There were significant differences between birth place and death time (χ² = 24.500, P < 0.05).

CONCLUSIONMaternal death time changed from 24 hours of delivery to prenatal or postnatal a long time. The maternal mortality causes and hospital delivery is an important factor affecting maternal time.

OBJECTIVETo analyze time trend and regional disparities in maternal mortality ratio (MMR) and major causes of maternal death in China from 1996 to 2010.

METHODSData used in this study were based on national maternal mortality surveillance system. From 1996 to 2005, it included 176 monitoring districts (countries) in 31 provinces, autonomous regions and municipalities in the inner land. From 2006 to the present, it covered 336 districts (countries). MMR, major causes of maternal death and their reduction margin, average annual reduction rate in different times and regions from 1996 to 2010 were analyzed. The trend and regional differences in MMRs and major causes of mortality were analyzed using Cochran-Armitage trend and Poisson Test.

RESULTSFrom 1996 to 2010, Chinese MMR has decreased by 53.2% from 64.7 in 1996 to 30.0 per 100 000 live births in 2010. MMR was higher in rural areas (30.1/100 000) than in urban areas (29.7/100 000), and highest in the west region (46.1/100 000) followed by the middle region (29.1/100 000) and the east region (17.8/100 000) in 2010. MMR in east, middle and west regions have decreased by 37.76%, 57.02% and 66.27% respectively from 1996 to 2010. The disparities between different regions were decreasing. From 2006 to 2010, MMR in rural areas has dropped to 1.82 times of the city, and that in the west was 3 times of the east. Obstetric hemorrhage was still the leading cause of maternal death, responsible for 47.9% maternal deaths in 1996 and 27.8% in 2010. The risk of death due to obstetric hemorrhage was decreasing.

CONCLUSIONThe MMR in China showed the decreasing trends. Although the regional disparities were still remarkable, they demonstrated narrowing trends. Interventions on maternal death should be focused in rural areas and west regions.

OBJECTIVETo analyze the maternal mortality ratio (MMR) of residential and migrant women in Beijing.

METHODSA retrospective study from 1995 to 2004 was performed to analyze data from the maternal death cases.

RESULTSThe MMR of resident and migrant of Beijing from 1995 to 2004 were 17.9 and 51.3 per ten thousand respectively. The main reasons of maternal deaths among residents were embolism (21.2%), hypertensive disorder complicating pregnancy (18.3%), postpartum hemorrhage (14.4%) and ectopic pregnancy/heart disease (9.6%). The main reasons of migrant maternal deaths were postpartum hemorrhage (25.2%), embolism (19.7%), hypertensive disorder complicating pregnancy (17.3%) and liver disease (9.5%). The avoidable deaths were accounted for 18.9%.

CONCLUSIONThe MMR in Beijing local residents was close to that in developed countries. To further reduce MMR in Beijing would depend on the better administration of related issues among floating population. Poor quatily delivery must be banned together with strengthening the training programs on health workers. It is also important to improve the knowledge and skills of medical staff for rescuing the complications of pregnancy and ectopic pregnancy.

OBJECTIVETo explore the factors associated with perinatal death of hepatic diseases in pregnancy (HDIP) and make feasible suggestions and measures for perinatal care of high risk patients.

METHODSThe 80 perinatal death cases of hepatic diseases in pregnancy (HDIP) during 1991-2000 in our hospital were analyzed retrospectively.

RESULTSThe perinatal mortality of HDIP in our hospital during the last 10 years was 17.99 approximately 65% was in utero death. Perinatal mortality was different between male (21.64%) and female (10.11%) (P<0.01). Compared first 5 years with last 5 years author found that the perinatal mortality of HDIP had no significant decrease (P>0.05). The perinatal mortality in city and suburbs had decreased, while in the floating population from other provinces the perinatal mortality had increased. The perinatal death was mainly caused by pregnancy induced hypertension (PIH) and asphyxia. But for the HBV carrier mothers the causes of death included umbilical cord problems, premature rupture of membrane and asphyxia.

CONCLUSIONSThe perinatal death mortality was increased by HDIP, deaths were essentially associated with pregnancy induced hypertension and asphyxia and the floating population and male gender were high risks. To enhance the management of HDIP or immigration, take effective therapies of hepatitis and improvement of resuscitation of newborns are critically important.

Pregnancy in patients with Eisenmenger syndrome (ES) is associated with high maternal mortality rates of 30%‒50%, or even up to 65% in the case of a cesarean section (Yuan, 2016). Here, we report a case of term pregnancy complicated with ES and severe pulmonary artery hypertension (PAH), which was managed by a multidisciplinary team (MDT) and resulted in an uncomplicated delivery via elective cesarean section. The goal of this study is to emphasize the importance of multidisciplinary approach in the management of pregnancy with ES, which can profoundly improve maternal and infant outcomes.

OBJECTIVETo explore the clinical manifestations and short-term prognosis of twin-twin transfusion syndrome (TTTS) in neonates with different disease stages, receiving different intrauterine interventions, or as blood donors and recipients.

METHODSThe study retrospectively collected 76 TTTS neonates who were hospitalized in the Neonatal Ward, Peking University Third Hospital. The participants were classified into mild TTTS (n=38) and severe TTTS groups (n=21), or into amnioreduction (n=20), laser surgery (n=21), and expectant therapy groups (n=32), or into donor (n=23) and recipient groups (n=30).

RESULTSThe severe TTTS group had higher incidences of brain injury, heart disease, asphyxia, and renal damage and in-hospital mortality rate compared with the mild TTTS group, but the differences had no statistical significance. The laser surgery group displayed decreasing trends in the incidences of brain injury, heart disease, and renal damage and in-hospital mortality rate compared with the amnioreduction and expectant therapy groups. The recipient group had higher incidences of heart diseases and pathological jaundice than the donor group (P<0.05). The donor group had higher incidences of asphyxia and renal damage than the recipient group, but with no significant difference.

CONCLUSIONSThe neonates with severe TTTS have higher rates of organ damages and in-hospital mortality. Intrauterine laser surgery seems to lead to a better prognosis compared with the amnioreduction and expectant therapy. The recipients are more susceptible to heart diseases and pathological jaundice, whereas the donors are more susceptible to asphyxia and renal damage.

PURPOSE: The neonatal mortality rate in Japan has currently been at the lowest level in the world. However, it is unclear whether there are still some potentially preventable neonatal deaths. We, therefore, aimed to examine the backgrounds of neonatal death and the possibilities of prevention in a region of Japan. MATERIALS AND METHODS: This is a population-based study of neonatal death in Shiga Prefecture of Japan. RESULTS: The 103 neonatal deaths in our prefecture between 2007 and 2011 were included. After reviewing by a peer-review team, we classified the backgrounds of these neonatal deaths and analyzed end-of-life care approaches associated with prenatal diagnosis. Furthermore, we evaluated the possibilities of preventable neonatal death, suggesting specific recommendations for its prevention. We analyzed 102 (99%) of the neonatal deaths. Congenital malformations and extreme prematurity were the first and the second most common causes of death, respectively. More than half of the congenital abnormalities (59%) including malformations and chromosome abnormality had been diagnosed before births. We had 22 neonates with non-intensive care including eighteen cases with congenital abnormality and four with extreme prematurity. Twenty three cases were judged to have had some possibility of prevention with one having had a strong possibility of prevention. Among specific recommendations of preventable neonatal death, more than half of them were for obstetricians. CONCLUSION: There is room to reduce neonatal deaths in Japan. Prevention of neonatal death requires grater prenatal care by obstetricians before birth rather than improved neonatal care by neonatologists after birth.

OBJECTIVETo understand the influencing factors on the death of infants born to HIV infected mothers in areas with high prevalence of HIV/AIDS in China.

METHODSBased on the follow-up cohort study targeting at HIV/AIDS infected pregnant women and their babies initiated in 2004, a survey on the death status and influencing factors on the infants born to HIV/AIDS infected mothers enrolled in this cohort from Jan.2004 to Nov.2007 was carried out during Aug.to Nov.2008 in seven counties of four provinces in China. A total of 498 pairs of HIV-infected mothers and their infants were enrolled and their related information was collected. Single factor and multiple factors Cox model methods were adopted for data analysis.

RESULTSThe total observed person-years of 498 infants was 406.22, among which, 45 infants died, and the mortality density was 110.78 per 1000 child-year. A single factor Cox model showed, the pregnancy in pre-period of HIV/AIDS and HIV/AIDS period (RR = 1.971, 95%CI: 1.143 - 3.396), living status of the pregnancy (RR = 3.062, 95%CI: 1.097 - 8.550), multipara women (RR = 0.517, 95%CI: 0.278 - 0.961), natural childbirth (RR = 0.561, 95%CI: 0.345 - 0.910), premature labor (RR = 5.302, 95%CI: 2.944 - 9.547), low birth weight (RR = 4.920, 95%CI: 2.691 - 8.994), mother-child pairs taking antiretroviral drugs (RR = 0.227, 95%CI: 0.121 - 0.428) and infants infected HIV (RR = 5.870, 95%CI: 3.232 - 10.660) could affect the infants death. The death of HIV-exposed infants was influenced by various factors. The death risk of infants born to HIV infected mothers who were in the danger of pre-period of HIV/AIDS and HIV/AIDS period was greater than the infants delivered by HIV infected mothers who were in preclinical period of HIV/AIDS (RR = 6.99, 95%CI: 1.92 - 25.64). The death risks were greater in the group that the women whose CD4(+)TLC count number lower than 200 cells/microl (RR = 2.05, 95%CI: 1.01 - 4.15). The infants whose mothers had no ARV treatment had higher possibility to die than the others (RR = 6.17, 95%CI: 1.62 - 23.26). The death risk of premature delivered infants was 2.87 times of mature delivered infants (95%CI: 1.12 - 7.35). The death risk of HIV/AIDS infected infants was 9.87 times of the HIV/AIDS uninfected infants (95%CI: 3.81 - 25.62).

CONCLUSIONSome measurements including improving HIV-infected pregnant women's immunity, reducing mother to child transmission of HIV and premature birth, low birth weight are beneficial to reducing infant mortality.
