AIM: Perinatal deaths occurring outside the neonatal intensive care unit (NICU) are rarely recorded in outcome studies, despite having a direct impact on perinatal statistics. Our aim was to investigate the timing and modes of perinatal deaths that occurred outside the NICU and changes over time. METHOD: We reviewed all perinatal deaths from 22 weeks of gestation onwards, without NICU admissions, during two periods in a Canadian tertiary mother and baby hospital and categorised deaths according to nine specific categories...

BACKGROUND: Maintaining optimal reproductive and litter performance is essential for meeting economic targets in commercial pig production. Treatment with exogenous gonadotropins in sows after weaning or in gilts after altrenogest treatment has been used to stimulate follicular development leading to more piglets born and eventually higher birth weights. The effect of peforelin on litter performance was investigated in 212 gilts, primi- and pluriparous sows in three herds. Animals were randomly allocated to three treatments 24 h after weaning: peforelin (P group), eCG (E group), and physiological saline solution (C group)...

We review critical factors associated with reproductive performance of female breeding pigs, their lifetime performance and herd productivity in commercial herds. The factors include both sow-level and herd-level factors. High risk sow-level groups for decreasing reproductive performance of female pigs are low or high parity, increased outdoor temperature, decreased lactation feed intake, single inseminations, increased lactation length, prolonged weaning-to-first-mating interval, low birth weight or low preweaning growth rate, a few pigs born alive at parity 1, an increased number of stillborn piglets, foster-in or nurse sow practices and low or high age at first-mating...

BACKGROUND: Maternal mortality and morbidity are the priority agenda for sub-Saharan Africa including Ethiopia. Uterine rupture is the leading cause of maternal and fetal death in developing countries. Limited evidence is available on the magnitude of uterine rupture; maternal and fetal outcomes of uterine rupture and factors associated with maternal death secondary to uterine rupture in Ethiopia. This study aimed to assess the magnitude of uterine rupture; maternal and fetal outcome of uterine rupture and factors associated with maternal death secondary to uterine rupture in Debremarkos Referral Hospital, Northwest Ethiopia...

BACKGROUND: Some studies, mainly in the older literature, observed a significant association between miscarriages and birth defects (BDs) occurring in the same sibship. However, few studies examined the BD/miscarriage relationship in depth. In addition nothing has been added to the underlying mechanisms possibly linking both events. The purpose of this work was to identify specific BDs associated with maternal miscarriages. In particular, it examined whether the risk depended on the number of losses, and to suggest the existence of specific factors for each BD/miscarriage association observed...

This case report presents a newborn boy with hypoglycaemia, anaemia, jaundice and severe coagulopathy during the first day of his life, imitating sepsis and disseminated intravascular coagulation. One week after the birth he was diagnosed with acute liver failure due to gestational alloimmune liver disease (GALD). Despite the fact that GALD is rare, it must be suspected in all unexplained stillborn children and infants with severe liver disease. If diagnosed, it is possible to prevent death and severe liver failure in future newborns by treating the affected women with immunoglobulin during pregnancy...

The consumption of colostrum at a low level can compromise the survival and growth of piglets. Therefore, this study aimed to evaluate the effect of farrowing induction on colostrum yield, IgG concentration and the survival and performance of piglets until the weaning. Sows of parity 3 to 7 were assigned into two groups: Control (n = 48), sows with spontaneous farrowing; and induction (n = 48), sows induced to farrow on day 114 of gestation with a PGF2 analogue. Colostrum and blood samples were collected from the sows, at farrowing and 24 hr later...

In 2011, a female Sumatran orangutan housed at Durrell Wildlife Conservation Trust became infertile following a massive antepartum hemorrhage in labor and the delivery of a stillborn infant. The placenta was infected with Pantoea sp. Hysterosalpingography (HSG) revealed blocked fallopian tubes, and pressurized fallopian tube perfusion was used to reverse the tubal occlusion. She subsequently conceived and following an intensive training program, we were able to measure umbilical artery waveform analysis for fetal well-being and placental localization to exclude placenta previa, which could complicate pregnancy and lead to catastrophic hemorrhage...

REVIEW
Kristin M Whitworth, Randall S Prather
Porcine Reproductive and Respiratory Syndrome (PRRS) causes severe reproductive failure in sows, as well as transplacental transfer of PRRS virus (PRRSV) to late-gestation fetuses, resulting in abortions, early farrowing, increased number of stillborn piglets, and weak neonatal piglets. PRRSV-infected boars present with anorexia and lethargy, and have decreased sperm quality. The gene for the cellular receptor that the PRRSV uses, Cluster of differentiation 163 (CD163), was edited using Clustered regularly interspaced short palindromic repeats (CRISPR)/Cas9 gene-editing technology to create biallelic DNA edits to the CD163 gene in 100% of the offspring...

Genetic variation in specific transcription factors during heart formation may lead to congenital heart disease (CHD) or even miscarriage. The aim of the present study was to identify CHD‑associated genes using next generation sequencing (NGS). The whole exome DNA sequence was obtained from a stillborn fetus diagnosed with tricuspid atresia and complete transposition of the great arteries using high‑throughput sequencing methods. Subsequently, genetic variants of CHD‑associated genes were selected and verified in 215 non‑syndromic CHD patients and 249 healthy control subjects using polymerase chain reaction combined with Sanger sequencing...

Adrenal histologic changes, including compact cell change (CCC), cystic change (CYC), and adrenal hemorrhage (AH), and their clinical correlations have only infrequently been investigated in stillbirth. We evaluated 75 third trimester singleton stillborns with complete autopsies (30 term and 45 preterm). A total of 58 had unexplained stillbirth and 17 had clinical placental abruption. The mothers were predominantly African-American (89%). CCC and CYC were diagnosed as cytoplasmic eosinophilia and cystic cavities in the definitive cortex, respectively...

Stress syndrome is usually caused by a mutation in the ryanodine receptor gene (ryr1) and it is widely studied in humans and swine populations. The protein product of this gene plays a crucial role in the regulation of calcium transport in muscle cells. A G>T mutation in the human ryr1 gene, which results in the replacement of a conserved arginine at position 614 where a leucine occurs at the same position as the previously identified Arg→Cys mutation reported in all cases of porcine stress syndrome (PSS)...

Ten pregnant sows were experimentally inoculated per os with T. gondii in order to investigate vertical and galactogenic transmission of the parasite and the evolution and maturation of the specific IgG humoral response in the sows and piglets. Five seronegative sows received 10(4)T. gondii (CZ isolate clone H3) sporulated oocysts during late-pregnancy (Exp. 1), three sows received 10(4) oocysts during mid-pregnancy (Exp. 2) and three sows from Exp. 1 (and two seronegative sows) were re-inoculated with 10(5) oocysts during a further pregnancy (late-pregnancy) (Exp...

Syphilis remains an important and preventable cause of stillbirth and neonatal mortality. About 1 million women with active syphilis become pregnant each year. Without treatment, 25% of them will deliver a stillborn baby and 33% a low birth weight baby with an increased chance of dying in the first month of life. Adverse pregnancy outcomes due to syphilis can be prevented by screening pregnant women, and treating those who test positive with a single dose of penicillin before 28 weeks' gestation. Areas covered: This manuscript covers the impact of syphilis on pregnancy outcome, the diagnosis of syphilis, with a special focus on point of care (POC) tests, and challenges to the introduction of POC tests, and their potential impact on the control and prevention of syphilis in resource limited settings...

The hypothesis was that a prolonged parturition impairs placenta expulsion and can lead to retained placentas in sows. Furthermore, we hypothesized that application of oxytocin around the time of expulsion of the first placental part improves placenta expulsion. We recorded 142 parturitions of 101 Yorkshire x Large White sows. We determined parity, gestation length, number of liveborn and stillborn piglets, farrowing duration (time between first and last piglet) and the outcome variables: number of expelled placental parts, placenta expulsion duration (time between first and last placental part), first placental part expulsion (time between last piglet and first placental part) and last placental part expulsion (time between last piglet and last placental part)...

Conjoined twins are suggested to result from aberrant embryogenesis. The two main theories proposed to explain the phenomena are fission and fusion. The incidence rate is 1 in 50,000 births; however, since about 60% of the cases are stillborn, the true incidence is approximated at 1 in 200,000. There is a higher predisposition towards female than male gender with a ratio of 3:1. Conjoined twins are classified based upon the site of attachment. The extent of organ sharing, especially the heart, determines the possibility and prognosis of a separation procedure...

Cerebellar disease can be congenital or acquired. Clinical signs of cerebellar disease include hypermetric gait in all limbs, normal to increased muscle tone, wide-based stance, swaying, intention tremor, and convulsions. Vestibular signs may be observed. Differential diagnoses for etiology include congenital (hypoplasia, abiotrophy, and lysosomal storage diseases), viral, bacterial, and toxic plants. Animals may present aborted as fetuses or stillborn, be affected at birth, develop disease at a few months old, or acquire the disease later in life...
