During pregnancy, the placenta undergoes a natural aging process, which is considered normal. However, it has been hypothesized that an abnormally accelerated and premature of may contribute to placenta-related health issues. Placental senescence linked several obstetric complications, including abnormal fetal growth, preeclampsia, preterm birth, stillbirth, with stillbirth being most challengi...

The normally formed singleton stillbirth deliveries occurring in Dudley Road Hospital in 1979, 1980 and 1981 were classified according to the primary aetiology. There was a higher than normal stillbirth rate in the Indian group which was almost entirely accounted for by the increased number of stillbirths falling into the 'intrauterine death before labour' group.

This study aimed to evaluate the prevalence of birthweight discordance among twins, to determine the risk cut-off point for birthweight discordance, and to clarify whether perinatal deaths are aggravated by birthweight discordance or by low birthweight itself. A population-based analysis of all twins born between 1995 and 1999 in Japan was conducted using data collected from national birth, dea...

Almost 10% of all births are preterm, and 2.2% are stillbirths. Recent research has suggested that environmental factors may be a contributory cause of these adverse birth outcomes. The authors examined the relation between ambient temperature and preterm birth and stillbirth in Brisbane, Australia, between 2005 and 2009 (n = 101,870). They used a Cox proportional hazards model with livebirth a...

OBJECTIVES Stillbirth is an important public health concern and its rate indicates the sanitary development of society. The purpose of this study is to determine the trend of stillbirth rates and its risk factors in Babol. METHODS A retrospective study was conducted based on the data of hospital charts of two major Gynecological wards in Shahid Yahyanejat and Babol clinic hospitals in Babol, ...

Death of calves around parturition is a matter of concern for dairy farmers. Relatively high stillbirth rates and unfavourable trends have been reported for Holstein heifers in the Netherlands and several other countries. In our study, we investigated herd differences, genetic parameters and genotype by environment interaction for heifer calf livability. A large dataset with data from calvings ...

BACKGROUND Although antenatal influenza vaccination is an important public health intervention for preventing serious infection in pregnant women and newborns, reported vaccine coverage is often <50%. Concern for the safety to the fetus is a commonly cited reason for vaccine hesitancy and refusal. The incidence of stillbirth following pandemic vaccination has been previously studied; however, n...

BACKGROUND Pregnancy and pregnancy loss may be linked to cardiovascular disease (CVD). However, the evidence is still inconsistent, especially in East Asians, whose reproductive patterns differ importantly from those in the West. We examined the associations of pregnancy, miscarriage, induced abortion, and stillbirth with CVD incidence among Chinese women. METHODS In 2004-2008, the nationwide...

BACKGROUND Stillbirth occurring after 28 weeks gestation affects between 1.5-4.5 per 1,000 births in high-income countries. The majority of stillbirths in this setting occur in women without risk factors. In addition, many established risk factors such as nulliparity and maternal age are not amenable to modification during pregnancy. Identification of other risk factors which could be amenable ...
