With data from the Office of Population Censuses and Surveys' longitudinal study the mortality of currently married women aged under 60 in 1971 was investigated in relation to the number of liveborn children reported at the 1971 census, adjusting for their husbands' social class. Women who had never had children experienced a higher mortality from many causes of death than the parous women, and this was probably due, at least in part, to selective factors. When the analysis was confined to parous women mortality from diabetes mellitus and cervical cancer increased significantly and oesophageal cancer decreased significantly with increasing number of liveborn children. Mortality from all circulatory diseases and from hypertensive disease, ischaemic heart disease, and subarachnoid haemorrhage tended to rise with parity, though the trends were not statistically significant. Mortality from breast cancer decreased significantly with the number of liveborn children, but only when nullipara were included in the analyses. These data suggest that there may be residual and cumulative effects of childbearing which influence patterns of disease in the long term.

Background: Cesarean hysterectomy for placenta accreta spectrum disorder may be associated with severe hemorrhage because of placental invasion of the myometrium and the uterovesical space or parametrium. It leads to serious complications, such as massive hemorrhage requiring massive transfusion, coagulopathy, bladder and ureteric injuries, need for intensive care unit admission and prolonged hospital stay. To reduce the complications of cesarean hysterectomy for placenta accreta spectrum disorder, ongoing efforts are being made to develop different surgical approaches.

Background: Group housing of sows has been extensively studied since the EU banned gestation crating. Well-managed group-housing promotes sow welfare, but the impact varies based on factors such as feeding, group characteristics, and environmental features. Adequate floor space, particularly directly post-mixing, is crucial for social interactions, natural behaviours, and to reduce injuries caused by aggression.

Genetic selection for growth rate has often been related with potential negative effects on various reproductive traits across different species. Using rabbit as a model, this study has evaluated for the first time how genetic selection for growth rate has affected feed efficiency, resource allocation, blood traits, reproductive performance and survival during five reproductive cycles in rabbit does. To this end, we used 88 reproductive rabbit females from two vitrified and rederived populations of the same paternal line, differing only in 18 generations of genetic selection for growth rate (n = 44 for R19V and n = 44 for RV37V).

Objective: To explore whether progesterone supplementation during luteal phase and early pregnancy after a natural frozen-thawed embryo transfer (NC-FET) cycle affects perinatal outcomes.
Design: A secondary data analysis study on the basis of 2 randomized control trials taking place during 2008-2011 and 2013-2018 at 2 university hospitals in Sweden.
Setting: Two university hospitals in Sweden.

The clinical implications of placental chromosomal mosaicism can be challenging for patients and health care providers. Key considerations include the specific characteristics of the chromosomal abnormality (such as size, gene content, and copy number), the timing of the mosaicism's onset during embryogenesis or fetal development, the types of tissues involved, and the level of mosaicism (the ratio of normal to abnormal cells within those tissues). Genetic counseling can help inform patients about the chances of having a live-born child with a chromosomal abnormality.
