The aim of this study was to examine the effect of a single administration of human chorionic gonadotrophin (hCG) during the establishment of the corpus luteum (CL) on progesterone (P4) concentration and pregnancy per artificial insemination (P/AI) in lactating dairy cows. Postpartum spring-calving lactating dairy cows (n = 800; mean ± SD days in milk and parity were 78.5 ± 16.7 and 2.3 ± 0.8, respectively) on 3 farms were enrolled on the study. All cows underwent the same fixed-time AI (FTAI) protocol involving a 7-d progesterone-releasing intravaginal device with gonadotrophin-releasing hormone (GnRH) administration at device insertion, prostaglandin at device removal followed by GnRH 56 h later, and AI 16 h after the second GnRH injection...

Due to the expression of paternal antigens by the embryo, pregnancy is considered as a semi-allograft and so immunological dysregulation is considered as one of the important causes in repeated implantation failure (RIF) and recurrent pregnancy loss (RPL). It has been revealed that lymphocytes immunotherapy (LIT) could be an appropriate approach to prevent pregnancy loss in such patients. Various mechanisms have been suggested for effectiveness of LIT such as enhancing expression of anti-paternal cytotoxic antibodies (APCA), progesterone-induced blocking factor (PIBF), anti-idiotypic antibodies (Ab2), and mixed lymphocyte reaction blocking antibodies (MLR-Bf), as well as reduction in the T helper 1/T helper 2 ratio and deviation in the pattern of cytokines production...

Uterine fibroids (leiomyomas or myomas), benign monoclonal tumors, are the most common benign tumors in women. Heavy or prolonged menstrual bleeding, abnormal uterine bleeding, resultant anemia, pelvic pain, infertility, and/or recurrent pregnancy loss are generally associated with uterine fibroids. Although curative treatment of this tumor relies on surgical therapies, medical treatments are considered the first-line treatment to preserve fertility and avoid or delay surgery. The aim of this review is to provide available and emerging medical treatment options for symptomatic uterine fibroids...

Fetal heart rate (FHR) data obtained from a non-stress test (NST) can be presented in a type of time series, which is accompanied by signal loss due to physical and biological causes. To recover or estimate FHR data, which is subjected to a high rate of signal loss, time series models [second-order autoregressive (AR(2)), first-order autoregressive conditional heteroscedasticity (ARCH(1)) and empirical mode decomposition and vector autoregressive (EMD-VAR)] and the residual bootstrap method were applied. The ARCH(1) model with the residual bootstrap technique was the most accurate [root mean square error (RMSE), 2...

Emergency liver transplantation (LT) for acute liver failure (ALF) is a life-saving treatment. Occurrence of this situation in the same patient twice is very rare. Herein, we describe a patient who underwent two emergency LTs for ALF, both from living donors. When she was 26 years old, she underwent a right lobe living donor LT (LDLT) from her sister for ALF due to use of herbal weight loss medications. The next 3 years were uneventful but another ALF developed during a terminal stage pregnancy (37th week)...

Background: Ovarian vein thrombosis is a rare complication of pregnancy. The representative complaints of patients with ovarian vein thrombosis are abdominal pain and fever. In some cases, however, fatal pulmonary embolism may develop. We report a case of pulmonary embolism presenting with severe hypotension and loss of consciousness during cesarean section possibly caused by ovarian vein thrombosis. Case presentation: A 25-year-old woman at 38 weeks 4 days of gestation was scheduled for repeat cesarean section...

As new research reveals, granulocyte colony-stimulating factor (G-CSF) plays an effective role in pregnancy success, considering that it not only affects the embryo implantation and ovarian function but also it promotes endometrial thickening and improves the pathophysiology of endometriosis, which all fundamentally lead to reducing pregnancy loss. In this review, we focus on the role of G-CSF in human reproduction. We summarized its role in ovulation, luteinized unruptured follicle syndrome, poor responders, improving repeated in vitro fertilization failure, endometrial receptivity and treatment of thin endometrium, and recurrent spontaneous abortion...

Two experiments were performed to test the hypothesis that administering PGF2α concurrent with timed artificial insemination (AI) in lactating dairy cows would enhance pregnancy per AI (P/AI). In experiment 1, lactating Holstein cows (n = 289) in one herd were enrolled after a non-pregnancy diagnosis (30-36 d after AI) to synchronize subsequent ovulation before AI. Cows were assigned randomly to receive (im) 10 mg of PGF2α concurrent with timed AI (Day 0; treatment) or no injection (control). Blood samples were collected on Days -3, 0, and 13 to determine serum concentrations of progesterone...

Unexplained recurrent pregnancy loss (uRPL) is associated with repeated embryo loss and endometrial repair with elevated endometrial expression of inflammatory cytokines, including IFN-γ. Notch signaling through its transcription factor recombination signal binding protein Jκ (RBPJ) regulates mechanisms including the immune response and repair after tissue injury. Initially, null mutation of RBPJ in the mouse uterus ( Pgrcre/+ Rbpjf/f ; Rbpj c-KO) results in subfertility, but we have found that these mice become infertile after pregnancy as a result of dysfunctional postpartum uterine repair, including delayed endometrial epithelial and myometrial regeneration...

Phosphatidylethanolamine (PE) is a major phospholipid species with important roles in membrane trafficking and reorganization. Accumulating clinical data indicate that the presence of circulating antibodies against PE is positively correlated with the symptoms of antiphospholipid syndromes (APS), including thrombosis and repeated pregnancy loss. However, PE is generally sequestered inside a normal resting cell, and the mechanism by which circulating anti-PE antibodies access cellular PE remains unknown. The studies presented here were conducted with synthetic PE-binding agents, plasma samples from patients with anti-PE autoimmunity, and purified anti-PE antibodies...

Background: Chronic insulin resistance (IR) is a basic part of the pathophysiology of gestational diabetes mellitus. Nutrition significantly impacts IR and weight loss reduces insulin levels, whereas weight gain increases the concentrations. Therefore, we surveyed the effect of nutrition intervention on IR in pregnant women and whether this effect is irrespective of weight gaining in accordance with Institute of Medicine limits. Methods: This prospective, randomized clinical trial was carried out among 150 primiparous pregnant mothers in fifteen health centers, five hospitals, and 15 private obstetrical offices in Isfahan...

AIM: Patients with an ultra-short uterine cervix as a result of large conization, repeated conization or radical trachelectomy (RT), are at high risk of preterm premature rupture of the membrane, which leads to preterm birth. We have commenced performing transabdominal cerclage (TAC) of the uterine cervix for these patients. In this study, we examined the safety of TAC and its impact on pregnancy. METHODS: We have performed TAC in 11 patients before pregnancy: in six after large cervical operations, such as repeated conization; and in five for difficulties with cervical cerclage after RT...

Women often come to the emergency department (ED) with signs and symptoms suggesting an early pregnancy loss; yet, little is known about their experience and how it relates to future outcomes. To improve patient outcomes and experiences of women seeking care for a pregnancy loss, research is required. However, recruitment of participants experiencing an event such as a pregnancy loss is challenging. The purpose of this article is to discuss the application of an electronic medical record (EMR)-based participant screening tool recruiting women seeking care for a pregnancy loss in the ED...
