CONTEXT: Undescended testes at birth may be caused by testosterone deficiency during fetal development. It is unclear whether the process of failed descent contributes to permanent endocrine impairment. OBJECTIVES: To evaluate the impact of age at treatment of undescended testes on endocrine and spermatogenic testicular function in middle-aged men. PATIENTS AND METHODS: Reproductive hormone and semen data of 357 men with previously undescended testes were evaluated with respect to age at correction of testicular position and compared to those of 709 controls with eutopic testes at birth and normozoospermia...

BACKGROUND: Maternal ethnicity is a recognized risk factor for stillbirth, such that South Asian women have higher rates than their Caucasian counterparts. However, whether maternal ethnicity is a risk factor for intrapartum outcomes is less clear. The aim of this study is to explore associations between maternal country of birth, operative vaginal delivery and emergency cesarean section, and to identify possible mechanisms underlying any such associations. METHODS: We performed a retrospective cohort study of singleton term births among South Asian, South East/East Asian and Australian/New Zealand born women at an Australian tertiary hospital in 2009-2013...

The major goal of animal production is to obtain abundant and healthy meat for consumers. Maternal food restriction (MFR) is often applied in farms to reduce production costs. However, the suitability of MFR in livestock animals is questionable, as this management may compromise maternal fitness due to a severe negative energetic balance and can induce Intrauterine Growth Restriction (IUGR) and prenatal programming in the offspring. Here, we sought to determine, using pregnant rabbits, the consequences of MFR on maternal endocrine and metabolic status and conceptus development...

We evaluated the changes in the pulsatility index (PI) and resistance index (RI) of fetal and maternal vessels and maternal serum angiogenic factors throughout pregnancy in 20 Kivircik ewes. They were examined for pregnancy detection on Day 30 after mating. The PI and RI during the pregnancies were followed using Doppler ultrasonography (USG) of the uterine artery, umbilical artery, fetal aorta, and fetal vena cava. Doppler USG was performed every 15 days beginning from the 40th day after mating. Blood samples were collected every 15 days starting from the day of mating...

INTRODUCTION: Fetal growth restriction is associated with short-term and long-term mortality and morbidity. We hypothesized that adverse outcome in children with fetal growth restriction at primary school age is associated with fetoplacental circulatory abnormalities. MATERIAL AND METHODS: Comprehensive ultrasonographic assessment of fetoplacental hemodynamics was performed in 72 growth-restricted fetuses prenatally, and short-term outcome data were collected. At the median age of 9 years, mortality and morbidity were determined using medical charts and questionnaires...

Although there is limited evidence that antepartum testing decreases the risk for fetal death in low-risk pregnancies, women with high-risk factors for stillbirth should undergo antenatal fetal surveillance. The strongest evidence supporting antepartum testing pertains to pregnancies complicated by intrauterine fetal growth restriction secondary to uteroplacental insufficiency. The main ultrasound-based modalities to determine fetal health are the biophysical profile, modified biophysical profile, and duplex Doppler velocimetry...

Severe stress in early life, such as childhood abuse and neglect, constitutes a major risk factor in the etiology of psychiatric disorders and somatic diseases. Importantly, these long-term effects may impact the next generation. The intergenerational transmission of maternal early life stress (ELS) may occur via pre-and postnatal pathways, such as alterations in maternal-fetal-placental stress physiology, maternal depression during pregnancy and postpartum, as well as impaired mother-offspring interactions...

Tendon afflictions are very common, and their negative impact is high both at the workplace and in leisure activities. Tendinopathies are increasing in prevalence and can lead to tendon ruptures, where healing is a long process with outcomes that are often disappointing. Human fetal progenitor tenocytes (hFPTs) have been recently tested in vitro as a potential cell source to stimulate tendon regeneration. The aim of the present study was to compare different commercial hyaluronic acid (HA) gels, which could be used to resuspend hFPTs in a formulation that would allow for good delivery of the cells...

Maternal obesity is growing in prevalence and is associated with increased morbidity and mortality for both mother and child. Women who are obese during pregnancy have a greater risk of metabolic complications such as gestational diabetes mellitus (GDM) as well as type 2 diabetes after pregnancy. Children of obese and/or GDM mothers have an increased susceptibility to congenital abnormalities and a range of cardio-metabolic disorders. The placenta is at the interface of the maternal and fetal environments and, its function per se, plays a major role in dictating the impact of maternal health on fetal development...

Recent studies have linked antenatal infection with Zika virus (ZIKV) with major adverse fetal and neonatal outcomes, including microcephaly. There is a growing consensus for the existence of a congenital Zika syndrome (CZS). Previous studies have indicated that non-placental macrophages play a key role in the replication of dengue virus (DENV), a closely related flavivirus. As the placenta provides the conduit for vertical transmission of certain viruses, and placental Hofbauer cells (HBCs) are fetal-placental macrophages located adjacent to fetal capillaries, it is not surprising that several recent studies have examined infection of HBCs by ZIKV...

Exposing human periodontal ligament stem cells (hPDLSCs) to animal proteins during cell expansion would compromise quality and safety of the hPDLSCs for clinical applications. The current study aimed to evaluate the replacement of animal based serum by human serum for the expansion of hPDLSCs. Human PDLSCs were cultured in culture media supplemented with 4 types of serums, Group A: fetal bovine serum (FBS), Group B: allogeneic human male AB serum (HS) and Group C in-house autologous (Auto-HS) and Group D: in-house allogeneic human serums (Allo-HS)...

Although neutrophils are known to be fundamental in controlling innate immune responses, their role in regulating adaptive immunity is just starting to be appreciated. We report that human neutrophils exposed to pregnancy hormones progesterone and estriol promote the establishment of maternal tolerance through the induction of a population of CD4(+) T cells displaying a GARP(+)CD127(lo)FOXP3(+) phenotype following antigen activation. Neutrophil-induced T (niT) cells produce IL-10, IL-17, and VEGF and promote vessel growth in vitro...

Syphilis remains the most common congenital infection worldwide and has tremendous consequences for the mother and her developing fetus if left untreated. Recently, there has been an increase in the number of congenital syphilis cases in the United States. Thus, recognition and appropriate treatment of reproductive-age women must be a priority. Testing should be performed at initiation of prenatal care and twice during the third trimester in high-risk patients. There are 2 diagnostic algorithms available and physicians should be aware of which algorithm is utilized by their testing laboratory...

This review summarizes our current knowledge on lung vasculogenesis and angiogenesis during normal lung development and the regulation of fetal and postnatal pulmonary vascular tone. In comparison to that of the adult, the pulmonary circulation of the fetus and newborn displays many unique characteristics. Moreover, altered development of pulmonary vasculature plays a more prominent role in compromised pulmonary vasoreactivity than in the adult. Clinically, a better understanding of the developmental changes in pulmonary vasculature and vasomotor tone and the mechanisms that are disrupted in disease states can lead to the development of new therapies for lung diseases characterized by impaired alveolar structure and pulmonary hypertension...

BACKGROUND: Shortening pre-hospital delay may decrease stillbirth rates and rates of babies born with a compromised health. Stillbirth may be preceded by a decrease in fetal movements. Mindfetalness has been developed as a response to the shortcomings of kick-counting for the monitoring of fetal movements by the pregnant woman. We do not know if practicing Mindfetalness may diminish pre-hospital delay. Nor do we know if practicing Mindfetalness may increase or decrease the percentage of women seeking health care for unfounded, from a medical perspective, worry for her fetus' well-being...

Herein, we evaluated whether Placental Mesenchymal Stromal Cells (PDMSCs) derived from normal and Preeclamptic (PE) placentae presented differences in the expression of G1/S-phase regulators p16(INK4A), p18(INK4C), CDK4 and CDK6. Finally, we investigated normal and PE-PDMSCs paracrine effects on JunB, Cyclin D1, p16(INK4A), p18(INK4C), CDK4 and CDK6 expressions in physiological term villous explants. PDMSCs were isolated from physiological (n = 20) and PE (n = 24) placentae. Passage three normal and PE-PDMSC and conditioned media (CM) were collected after 48h...

This study describes the changes observed in the placentas of mice experimentally infected with an abortigenic strain of EHV-1 at mid-pregnancy and euthanized at days 3 and 4 post-infection. We analyzed microscopic vascular alterations, cell proliferation and death by immunohistochemistry, and the expression of IFN-γ, TNF-α and the IL-10 by qPCR and flow cytometry. Infected mice showed slight respiratory signs and ruffled fur during the first two days post-infection. Virus isolation and DNA detection were positive only in the lungs of the infected mice...
