Prenatal diagnosis of a lean umbilical cord: a simple marker for the fetus at risk of being small for gestational age at birth. (1/1267)

OBJECTIVE: The purpose of this study was to investigate whether the prenatal diagnosis of a 'lean' umbilical cord in otherwise normal fetuses identifies fetuses at risk of being small for gestational age (SGA) at birth and of having distress in labor. The umbilical cord was defined as lean when its cross-sectional area on ultrasound examination was below the 10th centile for gestational age. METHOD: Pregnant women undergoing routine sonographic examination were included in the study. Inclusion criteria were gestational age greater than 20 weeks, intact membranes, and singleton gestation. The sonographic cross-sectional area of the umbilical cord was measured in a plane adjacent to the insertion into the fetal abdomen. Umbilical artery Doppler waveforms were recorded during fetal apnea and fetal anthropometric parameters were measured. RESULTS: During the study period, 860 patients met the inclusion criteria, of whom 3.6% delivered a SGA infant. The proportion of SGA infants was higher among fetuses who had a lean umbilical cord on ultrasound examination than among those with a normal umbilical cord (11.5% vs. 2.6%, p < 0.05). Fetuses with a lean cord had a risk 4.4-fold higher of being SGA at birth than those with a normal umbilical cord. After 25 weeks of gestation, this risk was 12.4 times higher when the umbilical cord was lean than when it was of normal size. The proportion of fetuses with meconium-stained amniotic fluid at delivery was higher among fetuses with a lean cord than among those with a normal umbilical cord (14.6% vs. 3.1%, p < 0.001). The proportion of infants who had a 5-min Apgar score < 7 was higher among those who had a lean cord than among those with normal umbilical cord (5.2% vs. 1.3%, p < 0.05). Considering only patients admitted in labor with intact membranes and who delivered an appropriate-for-gestational-age infant, the proportion of fetuses who had oligohydramnios at the time of delivery was higher among those who had a lean cord than among those with a normal umbilical cord (17.6% versus 1.3%, p < 0.01). CONCLUSION: We conclude that fetuses with a lean umbilical cord have an increased risk of being small for gestational age at birth and of having signs of distress at the time of delivery.  (+info)

The 'Mickey Mouse' sign and the diagnosis of anencephaly in early pregnancy. (2/1267)

OBJECTIVES: To assess the sonographic screening for anencephaly in the first trimester in a low-risk obstetric population. METHODS: Since 1994, 5388 women attended our clinic for a first-trimester scan (11-14 weeks of gestation) and screening for structural and chromosomal abnormalities. The patients underwent transabdominal scanning, and transvaginal scanning if necessary. RESULTS: The ultrasonographic appearances of anencephaly in the first trimester are different from the familiar second-trimester signs. The cerebral hemispheres are present and exposed to the surrounding amniotic fluid. The ultrasound appearances in the coronal section of the head are best described as 'Mickey Mouse face'. There were six cases of anencephaly (incidence 1.1:1000). All cases were diagnosed in the first trimester and five demonstrated this sign. There were no false-positive diagnoses. The crown-rump length was significantly reduced in all affected fetuses. CONCLUSION: First-trimester ultrasonographic diagnosis of anencephaly is accurate, but sonographers should be familiar with the ultrasound appearances that are different from those in the second trimester.  (+info)

Adrenomedullin production is increased in normal human pregnancy. (3/1267)

OBJECTIVE: Adrenomedullin, a recently discovered vasoactive peptide originally identified in pheochromocytoma, has been found to be increased in the plasma of pregnant women at term. This study was designed to elucidate whether adrenomedullin secretion is dependent on gestational age and the possible source and function of this peptide in human pregnancy. STUDY DESIGN: Adrenomedullin concentrations were determined by RIA in amniotic fluid and maternal plasma obtained from 110 pregnant women between 8 and 40 weeks of gestation. Subjects were stratified into five groups according to gestational age. In term patients (n = 15), adrenomedullin was also measured in the umbilical artery and vein separately. RESULTS: High concentrations of adrenomedullin were present in plasma and amniotic fluid samples from patients in the first, second and third trimester. There was no significant difference in mean maternal plasma concentration of adrenomedullin between the five patient groupings. Amniotic fluid adrenomedullin concentrations decreased from 81.2 +/- 11.7 pg/ml at 8-12 weeks of gestation to 63.7 +/- 6.0 pg/ml at 13-20 weeks of gestation and then increased at 21-28 weeks of gestation to 99.1 +/- 10.4 pg/ml. A further increase was found in samples collected after 37 weeks of gestation (132.6 +/- 10.1 pg/ml). In the umbilical vein, adrenomedullin concentration was higher (P < 0.05) than in the artery (65.7 +/- 6.1 pg/ml and 48.5 +/- 5.2 pg/ml respectively), suggesting that adrenomedullin in the fetal circulation derives from the placenta. CONCLUSIONS: Our results demonstrate the presence of adrenomedullin in maternal plasma and amniotic fluid throughout gestation, and show that its production starts very early in gestation, suggesting that this hormone may have an important role in human reproduction, from implantation to delivery.  (+info)

Amniotic fluid concentrations of dimeric inhibins, activin A and follistatin in pregnancy. (4/1267)

OBJECTIVE: The feto-placental unit is the major source of circulating concentrations of inhibin A and activin A in human pregnancy. The aim of this study was to measure the amniotic fluid concentrations of inhibin A, inhibin B, activin A and follistatin in pregnancies bearing male and female fetuses. DESIGN AND METHOD: Amniotic fluid samples collected by amniocentesis were stored at -20 degrees C. Dimeric inhibins, 'total' activin A and 'total' follistatin were measured using specific two-site enzyme immunoassays. Samples were assayed blindly and the information on fetal sex was obtained from the cytogenetics laboratory. RESULTS: Data show that amniotic fluid concentrations of inhibin A, inhibin B and activin A gradually increase with gestation whilst concentrations of follistatin are similar between weeks 15 and 20 of pregnancy. Mean amniotic fluid levels of inhibin A and inhibin B at 16 and 17 weeks gestation and mean activin A levels at 15 and 16 weeks gestation are considerably lower in pregnancies with male (n=24) compared with female (n=28) fetuses. Levels of follistatin are not different in the male and female fetal pregnancies at any studied gestation. CONCLUSIONS: The results indicate that amniotic fluid contains high concentrations of inhibins (A and B), activin A and follistatin in early pregnancy suggesting that these hormones are produced by the fetal membranes and may be involved in the development of the fetus.  (+info)

SMN protein analysis in fibroblast, amniocyte and CVS cultures from spinal muscular atrophy patients and its relevance for diagnosis. (5/1267)

Spinal muscular atrophy (SMA) is an autosomal recessive neuromuscular disorder caused by the homozygous absence of the telomeric copy of the survival motor neuron (SMNt) gene, due to deletion, gene conversion or point mutation. SMNt and its homologous centromeric copy (SMNc) encode the SMN protein, which is diffusely present in the cytoplasm and in dot-like structures, called gems, in the nucleus. We have studied the SMN protein in different cell cultures, including fibroblasts, amniocytes and CVS cells from SMA individuals and controls. By immunofluorescence analysis we found a marked reduction in the number of gems in fibroblasts, amniocytes and chorionic villus cells of all SMA patients and foetuses, independent of the type of the genetic defect. We also show that immunolocalisation of the SMN protein may be a useful tool for the characterisation of particular patients of uncertain molecular diagnosis.  (+info)

Secretory leukocyte protease inhibitor concentration increases in amniotic fluid with the onset of labour in women: characterization of sites of release within the uterus. (6/1267)

Secretory leukocyte protease inhibitor is a potent inhibitor of neutrophil function, a mediator of mucosal immunity and an inhibitor of NF|gkB regulated inflammatory responses. However, its source, function and regulation within the uterus during pregnancy and at parturition are not well defined. In amniotic fluid, the concentration of secretory leukocyte protease inhibitor increased significantly from 2nd trimester (24+/-3 ng/ml; mean+/-s.e.m.; n=20) to term (751+/-53 ng/ml; P<0.05; n=15) with a further profound increase (P<0.005) with the onset of labour (3929+/-1076 ng/ml; n=15). To establish the intra-uterine sites of secretion, explants (n=6 different patients per tissue) were collected at term after elective caesarean section. High levels of secretory leukocyte protease inhibitor were released by decidua (135.2+/-12.4 pg/mg; mean+/-s.e.m.) and chorio-decidua (325.1+/-26.4 pg/mg) with less by amnion (55.6+/-6.0 pg/mg) and placenta (9.2+/-1.9 pg/mg). Intense immunoreactivity for secretory leukocyte protease inhibitor was detected predominantly in decidua parietalis cells adherent to the chorion laeve and myometrium, and also in decidua basalis. We propose that, within the pregnant uterus, secretory leukocyte protease inhibitor is released by decidua, fetal membranes and potentially the fetal lung. The increase in secretory leukocyte protease inhibitor may act to modulate pro-inflammatory paracrine interactions for the maintenance of pregnancy and limit those occurring at parturition within the uterus.  (+info)

Secretion of matrix metalloproteinase-2, matrix metalloproteinase-9 and tissue inhibitor of metalloproteinases into the intrauterine compartments during early pregnancy. (7/1267)

Matrix metalloproteinases (MMPs) are important enzymes in tissue remodelling, a key event for the development of the fetal membranes and placenta and establishing the feto-maternal interface during early pregnancy. This study has examined the secretion of the gelatinases, MMP-2 (72 kDa) and MMP-9 (92 kDa), and the endogenous tissue inhibitors of metalloproteinases (TIMPs) into extra-embryonic coelomic and amniotic fluids, the two principal intra-uterine compartments of the first trimester, and compared them to amniotic fluid collected later in gestation. In extra-embryonic coelomic fluid, gelatin zymography demonstrated that MMP-2 (72 kDa) was the predominant gelatinase, with some MMP-9 present. A broad range of TIMPs corresponding to TIMP-1 and TIMP-2, glycosylated and unglycosylated TIMP-3 and TIMP-4 was detected in this compartment by reverse zymography and immunoblot analyses. There was little gelatinase or TIMP activity in amniotic fluid in the first trimester. In amniotic fluid from the second trimester after fusion of the membranes obliterating the extra-embryonic coelom, and at term elective caesarean section, MMP-2 is the predominant gelatinase present, with a broad spectrum of TIMPs. These findings demonstrate that predominantly MMP-2 and also MMP-9, regulated by a range of TIMPs, are involved in intra-uterine tissue remodelling during the establishment of pregnancy.  (+info)

Vascular endothelial growth factor is bound in amniotic fluid and maternal serum. (8/1267)

To study vascular endothelial growth factor (VEGF) and placenta growth factor (PlGF) concentrations and their possible binders, serum from 22 non-pregnant and 55 pregnant women (15 at weeks 10-13; 40 at term), umbilical vein (n = 24) and artery (n = 13) and amniotic fluid (a pool of 50 at weeks 15-17; 11 at term) were assessed for VEGF and PlGF by an enzyme-linked immunosorbent assay. In amniotic fluid and maternal serum VEGF concentrations were <16 ng/ml and added VEGF was not recovered. VEGF was detected in serum from mothers post-partum (137 +/- 142 ng/l, mean +/- SD), umbilical artery (421 +/- 288 ng/l) and vein (502 +/- 339 ng/l) and non-pregnant controls (182 +/- 147 ng/l), and added VEGF was fully recovered. PlGF was detected in pregnancy serum (52 +/- 23 ng/l early pregnancy; 439 +/- 217 ng/l term pregnancy) and in amniotic fluid (early pregnancy 56 ng/l; term pregnancy 30 +/- 18 ng/l). PlGF was fully recovered in all samples. Gel filtration and isoelectric focusing revealed that in maternal serum and amniotic fluid [125I]VEGF was bound to a protein with an Mr of 400-700 kDa and an isoelectric point of approximately 8. This protein was not identical with alpha-2-macroglobulin (by an immunofluorometric assay), pregnancy zone protein or pregnancy associated plasma protein-A (by immunodiffusion). In conclusion, VEGF-binding activity is present in amniotic fluid and maternal blood. It disappears after delivery and is not detectable in fetal or non-pregnant serum.  (+info)

N2 - Mesenchymal stem cells (MSCs) have generated great interest in the fields of regenerative medicine and immunotherapy because of their unique biological properties. Among MSCs, amniotic fluid stem cells (AFS) have a number of characteristics that make them attractive candidates for tissue engineering and cell replacement strategies, particularly for perinatal medicine. If various neonatal conditions, including birth asphyxia, preterm birth, and congenital abnormalities, which result in long-lasting severe impairments, could be predicted during pregnancy, it would allow collection of small samples of amniotic fluid cells by amniocentesis.

Firstly, we analyzed hAFC samples for the expression of germ cell markers; in agreement to previous reports [11], we observed a consistently high expression of OCT4 and CD133. However, when we examined additional markers we did not observe expression of genes specific to germ cell differentiation. In this regard, it was reported that hAFCs had the ability to form embryoid bodies (EBs) when cultured under conditions without anti-differentiation factors and without contact to feeder cells. Moreover, the formation of such three-dimensional multicellular aggregates was accompanied by a decrease in stem cell marker expression and by the induction of differentiation into different cell lineages [23]. Hence herein hAFCs kept under a stem cell culture system yielded a high number of clones that when cultured in suspension without anti-differentiation factors, spontaneously formed multicellular EBs and harbored high differentiation potential. Moreover, when we cultured EBs in the presence of germ cell ...
TY - JOUR. T1 - Ethanol alters the osteogenic differentiation of amniotic fluid-derived stem cells. AU - Hipp, Jennifer A.. AU - Hipp, Jason D.. AU - Atala, Anthony. AU - Soker, Shay. PY - 2010/10/1. Y1 - 2010/10/1. N2 - Background: Fetal alcohol spectrum disorder (FASD) is a set of developmental defects caused by prenatal alcohol exposure. Clinical manifestations of FASD are highly variable and include mental retardation and developmental defects of the heart, kidney, muscle, skeleton, and craniofacial structures. Specific effects of ethanol on fetal cells include induction of apoptosis as well as inhibition of proliferation, differentiation, and migration. This complex set of responses suggests that a bioinformatics approach could clarify some of the pathways involved in these responses. Methods: In this study, the responses of fetal stem cells derived from the amniotic fluid (AFSCs) to treatment with ethanol have been examined. Large-scale transcriptome analysis of ethanol-treated AFSCs ...
In recent years, great interest has been devoted to the use of Induced Pluripotent Stem cells (iPS) for modeling of human genetic diseases, due to the possibility of reprogramming somatic cells of affected patients into pluripotent cells, enabling differentiation into several cell types, and allowing investigations into the molecular mechanisms of the disease. However, the protocol of iPS generation still suffers from technical limitations, showing low efficiency, being expensive and time consuming. Amniotic Fluid Stem cells (AFS) represent a potential alternative novel source of stem cells for modeling of human genetic diseases. In fact, by means of prenatal diagnosis, a number of fetuses affected by chromosomal or Mendelian diseases can be identified, and the amniotic fluid collected for genetic testing can be used, after diagnosis, for the isolation, culture and differentiation of AFS cells. This can provide a useful stem cell model for the investigation of the molecular basis of the diagnosed
Bone tissue engineering strategies require cells with high proliferative and osteogenic potential as well as a suitable scaffold to support the development of these as they form new bone tissue. In this study, we evaluated whether the differentiation stage of amniotic fluid stem cells (AFSC) could enhance the regeneration of critical sized femoral defects in a rat model. For this purpose, AFSC were seeded onto a starch-poly(ε-caprolactone) (SPCL) scaffold and were cultured in vitro in osteogenic culture media for different periods of time in order to obtain: i) undifferentiated cells, ii) cells committed to the osteogenic phenotype and iii) osteoblast-like cells. In vitro results indicate that AFSC were considered to be osteogenically committed by the end of week 2 and osteoblastic-like after week 3 in culture. Constructs composed of AFSC-SPCL scaffolds from each differentiation stage were implanted into critical sized femoral defects. The quality of new tissue formed in the defects was ...

Here we selected eight genes including FOLR3, CDH6, CXCL12, NPPB, cyclin D2, IGF2, KRT8, and CRABP2, for verifying results from the chip data because these genes showed gradual and drastic changes in expression patterns. It has not been reported to date that these selected genes are directly related to cellular senescence. Although an interest in IGF2 derives mostly from its connection with IGF1 and how the IGF1/GH axis appears to regulate aging in model organisms, IGF2s role in aging is unproven (17). Recently, it was reported that overall IGF2 expression increased during senescence of human prostate epithelial cells due to the loss of IGF2 imprinting (18). However, our RT-qPCR result, which did not match our chip data, showed that IGF2 mRNA levels were increased by the 6th passage and then abruptly dropped by the 10th passage (Fig. 4). The discrepancy between our result and theirs might be caused by our using different cell types. Or, IGF2 might not be a main regulator of cellular senescence. ...
Scientists hailing from the Wake Forest Institute for Regenerative Medicine (WFIRM) have been putting their efforts into a revolutionary approach for helping chronic kidney disease sufferers get a firmer grasp on their situation and repair any tissues that may have been ravaged by the disease. This solution comes in the form of human amniotic fluid-derived stem cells, which the scientists have posited would not only repair tissue, but even help recover kidney function that has been lost. The researchers at WFIRM have been at the cutting edge of stem cell research for quite some time, with their teams also pioneering the equally impressive 3D bioprinting of organs and tissues. According to the scientists, the amniotic fluid-derived stem cells are unique in that they can be utilized as universal cell sources, meaning they can fill in for numerous different types of cells, while simultaneously benefiting the entirety of the organism with anti-inflammatory properties and potential ...

Whether these cells are as versatile as embryonic stem cells remains to be determined, said Atala, but the current finding is certainly encouraging.. Atala stopped short of calling the cells pluripotent, which means the ability to form many cell types. He said while the cells meet some of the characteristics of pluripotency, such as versatility, they do not form tumors when implanted in animals, which is also considered a characteristic. The fact that the amnion cells are less likely to form tumors may be one advantage that they have over embryonic stem cells in their potential for clinical use..

Restricted Item. Print thesis available in the University of Auckland Library or available through Inter-Library Loan. Three major cell types, termed E, F and AF, constitute cultures of second trimester human amniotic fluids and are widely used for the prenatal diagnosis of inherited disorders of metabolism. Current evidence suggests that the predominant cell type, the AF cells, retain properties of trophoblast and it has been proposed that they are derived from the trophoblast of the placenta. Since the trophoblast is thought to be the site of the aromatization of C19 -steroids in the placenta, it was considered that AF type amniotic fluid cell cultures should possess this steroidogenic activity. Investigations were therefore undertaken to explore this hypothesis. Initial experiments involved culturing AF and F type cells in the presence and absence of dehydroepiandrosterone sulphate and subsequently incubating the cell layers with [4-14C] androstenedione. Isolation and identification of the ...
Tendons are highly prone to injury and the intrinsic hypocellularity and hypovascularity make their natural healing extremely slow and inefficient when severed damaged. Surgical repair with grafts is common but unsuccessful in a long term basis. The development of tissue engineering strategies based on stem cells explores a natural endogenous system of regeneration with potential for tendon application. We propose to establish biochemical culturing conditions to assess the tenogenic potential of human adipose stem cells (hASCs) and amniotic fluid-derived stem cells (hAFSCs), known for their proliferative and differentiation capacities. Since several growth factors (GFs) participate in tendon formation and ECM synthesis, these GFs were added to the culture medium to stimulate tenogenic differentiation of these cells. This study also envisions the application of hASCs and/or hAFSCs in cell-based strategies for tendon repair ...

In a previous study, we isolated human amniotic fluid (AF)-derived mesenchymal stem cells (AF-MSCs) and utilized normoxic conditioned medium (AF-MSC-norCM) which has been shown to accelerate cutaneous wound healing. Because hypoxia enhances the wound healing function of mesenchymal stem cell-conditioned medium (MSC-CM), it is interesting to explore the mechanism responsible for the enhancement of wound healing function. In this work, hypoxia not only increased the proliferation of AF-MSCs but also maintained their constitutive characteristics (surface marker expression and differentiation potentials). Notably, more paracrine factors, VEGF and TGF-β1, were secreted into hypoxic conditioned medium from AF-MSCs (AF-MSC-hypoCM) compared to AF-MSC-norCM.

Background: Spontaneous ascitic fluid infection (SAI) is an acute infection of ascitic fluid. SAI has three subtypes; SBP, CNNA, MNB. The prototype is Spontaneous bacterial peritonitis (SBP). SBP is a frequent and serious complication in patients with cirrhosis leading to significant mortality and morbidity. Diagnosis of SBP is mainly established by elevated polymorphonuclear leukocyte count and positive ascitic fluid bacterial culture. Methodology: Records of patients with suspected diagnosis of Spontaneous ascitic fluid infection were analyzed in the present study. Patients admitted in the last one year i.e., between January 2014 to December 2014 with ascites secondary to cirrhosis were included. All patients with decompensated cirrhosis had undergone ascitic fluid paracenetesis after admission to the hospital. Ascitic fluid was centrifuged and analyzed for Total protein, Albumin, Total and Differential leukocyte count. Ascitic fluid was cultured by using BacTec method to determine the growth ...
This study showed that term amniotic fluid is a relatively rich source of MSCs having high expansion capacities and features similar to MSCs isolated from other sources. We also showed that harvesting amniotic fluid at term caesarean section deliveries by catheter resulted in much higher collection volumes compared with 10-20 ml volumes that were harvested in previous studies of term or pre-term amniotic fluid [24-26]. We were able to harvest on average about 400 ml of fluid from the 20 samples. Comparing the TAF-MSCs described in this study with MSCs isolated from BM and AD, we show that they share a significantly similar transcriptional profile. Taken together, these results suggest that TAF-MSCs may be an alternative and complimentary source of MSCs with features making them highly attractive for further investigation in in-vivo pre-clinical functional assessments.. There are only a limited number of publications characterizing term human amniotic fluid cells [24-26]. In line with these ...

The miRNAs are a new class of nucleic acids that show promise as useful clinical biomarkers for several diseases (6-8). Our data revealed that the expressions of miR-125b-2, miR-155, and miR-3156 in the amniotic fluid culture were significantly higher in pregnant women carrying fetuses with DS than in the control group. The study sample size was small; however, to the best of our knowledge, our study is the first to demonstrate significant differences in miRNA expression in cell cultures between fetuses with and without DS. Many studies have evaluated the association of miRNA expression levels with a variety of pathologic conditions, including preeclampsia, fetal congenital cardiac defects, neural tube defects, fetal growth retardation, and DS (9-15). The miRNAs encoded by hsa 21 (i.e., hsa-miR-99a, let-7c, miR-125b-2, miR-155, and miR-802) have been proven to correlate with the complex and variable phenotypes of DS and were shown to be overexpressed in the heart, frontal cortex, and hippocampus ...

De Coppis team has demonstrated that intravenous transplantation of amniotic fluid stem (AFS) cells enhances the muscle strength and improves the survival rate of the affected animals. This is the first study to demonstrate the functional and stable integration of AFS cells into skeletal muscle, highlighting their value as a cell source for the treatment of muscular dystrophies.. However, the research is still at a relatively early stage as the work has only been carried out in animal models.. Dr Coppi said: Spinal muscular atrophy is a genetic disease affecting one in 6,000 births. It is currently incurable and in its most severe form children with the condition may not survive long into childhood. Children with a less severe form face the prospect of progressive muscle wasting, loss of mobility and motor function. There is an urgent need for improved treatments.. We are excited by this potential new approach for regenerating skeletal muscle tissue, but much more research is needed. We now ...

After a long wait we had the follow-up ultrasound today. Owen has been a very active boy for a while now which has helped us make it through the wait with much optimism. The ultrasound was at 1:30 and our whole clan was allowed into the ultrasound room. The clan being my mom and dad, Joshs mom and sister and of course Josh and I. As the ultrasound progressed every update was better than the last. First off the amniotic fluid level was right on (high amniotic fluid levels are common with trisomy 18 babies). His choroid plexus cysts had resolved, as well as the calcium deposit on his heart. They were just gone, they said there was a good chance they would resolve, but to see it live in person was nothing short of a miracle for us!!! And finally all of the measurements were done and he came in at 3 lbs. 1oz. and measured within one day of his due date, which we were informed never happens. The measurement was the most important thing to us. The geneticist in Little Rock had told us that babies ...

Amniotic fluid has been used for more than 70 years for prenatal diagnosis (1). It is extracted, by a procedure called amniocentesis, generally between the 14th and 20th weeks of pregnancy, to assess for genetic birth defects. In addition to the fluid required for testing, the doctor will also withdraw a small amount (a few milliliters) of additional fluid, in case any

Intra-amniotic infections are associated with an increased risk of preterm delivery, which, in turn, may be associated with neurological sequelae in former preterm infants [80]. Microbial presence in the amniotic fluid may elicit maternal and fetal inflammatory response that are then responsible for neonatal complications. The association between elevated inflammatory cytokines IL-1β and IL-6 in the amniotic fluid and subsequent white matter injury has been noted in preterm infants [81]. Elevated levels of inflammatory cytokines in the cord blood including IL-1β, IL-6 IL-8, and TNF-α have also been shown to correlate with neonatal cerebral lesions as detected by MRI after parturition in human premature infants [82]. Furthermore, clinical evidence shows that elevated inflammatory response in the perinatal period has been demonstrated to correlate with long-term neonatal morbidities including cerebral palsy [83], psychomotor deficits [8], and non-neurological diseases including necrotizing ...
Definition : Immunoassay reagents intended to perform quantitative analyses on amniotic fluid samples obtained from pregnant women to determine the ratio of phospholipids (i.e., surfactants) to albumin. These tests are typically used to estimate fetal lung maturity and to assess the associated risk of respiratory distress syndrome if birth occurs. The predictive values are less than 40mg/g for immature lungs and more than 70mg/g for mature lungs, but values may change as pregnancy progresses.. Entry Terms : Reagents, Immunoassay, Pregnancy, Phospholipid/Albumin Ratio. UMDC code : 20669 ...
Objective: RANTES (regulated on activation, normal T cell expressed and secreted), a potent and versatile chemokine, is capable of attracting monocytes, lymphocytes, basophils, and eosinophils. This cytokine has been implicated in the regulation of the inflammatory response and in the recruitment of macrophages to the implantation site in early pregnancy. RANTES messenger ribonucleic acid and protein have been detected in fetal tissue and first-trimester trophoblast in response to bacterial endotoxin. The purpose of this study was to determine whether intrauterine infection, parturition (preterm and term), and gestational age affect the amniotic fluid concentrations of RANTES in human pregnancy. Study Design: A cross-sectional study was designed to examine the relationship between labor, microbial invasion of the amniotic cavity, gestational age, and RANTES expression in amniotic fluid. Amniotic fluid was obtained from 214 women in the following groups: (1) midtrimester (n = 22), (2) preterm ...
Our findings confirm the hypothesis that medical induction of labour is related to an increased risk of AFE, added Dr. Kramer. Although the absolute risk increase of AFE for women is very small (four or five total cases and one or two fatal cases per 100,000 women induced) and is unlikely to affect the decision to induce labour in the presence of compelling clinical indications, women and physicians should be aware of this risk if the decision is elective. ...

Scientist have identified a link between exposure to high levels of oestrogen sex hormones in the womb and the likelihood of developing autism. The discovery adds further evidence to support the prenatal sex steroid theory of autism first proposed 20 years ago.. In 2015, a team of scientists at the University of Cambridge and the State Serum Institute in Denmark measured the levels of four prenatal steroid hormones, including two known as androgens, in the amniotic fluid in the womb and discovered that they were higher in male foetuses who later developed autism. These androgens are produced in higher quantities in male than in female foetuses on average, so might also explain why autism occurs more often in boys. They are also known to masculinise parts of the brain, and to have effects on the number of connections between brain cells.. Today, the same scientists have built on their previous findings by testing the amniotic fluid samples from the same 98 individuals sampled from the Danish ...
The present study investigated: (a) the presence of antiphospholipid antibodies and (b) the obstetric outcome in healthy pregnant women showing false-positive TORCH-Toxoplasmosis, Other: syphilis, varicella-zoster, Rubella, Cytomegalovirus (CMV), and Herpes infections-results. Data from 23 singleton healthy pregnancies with false-positive TORCH results were collected. Each woman was systematically screened for TORCH IgG and IgM during the pre-conception assessment and/or at the beginning of pregnancy. In the presence of IgM positivity, when indicated (CMV, toxoplasmosis, rubella, herpes simplex virus), IgG avidity was evaluated and, if possible, polymerase chain reaction was performed on an amniotic fluid sample in order to distinguish between primary infection or false positivity ...
Not only does death linger on as a memory in the nervous system, but suicides will often choose a method that reflects the prototype of their birth experiences. So, those strangled on the umbilical cord may hang themselves, or an overdose of pills is chosen by someone who was drugged at birth. Why? Because of the prototype; for a neonate strangling on the cord, further strangling would have ended the agony. Those drowning in amniotic fluid at birth will opt for death by drowning. Case in point: the writer-actor Spalding Gray had a lifetime obsession with drowning. He used to swim in the ocean as far out as he possibly could until the point of exhaustion and then struggled to try and make it back. He killed himself by jumping off the Staten Island Ferry in the middle of the night. I hypothesize that he may have been drowning at birth and the end of the original sequence would be drowning. In other words, I think he died like he was born. This is never to minimize the pain in the present; ...

We just had our 20 week anatomy scan today, and for the most part things looked good with the exception of some renal abnormalities. DH was born with whats called vesiculoureteral reflux and had to have surgery as a baby to reattach his ureters to his bladder. Based on todays scan, we think that may be whats going on with our first LO. She has dilated collecting systems, normal kidneys,, normal bladder, and normal amniotic fluid levels. We are being referred to the Pediatric Nephrologist (who DH and I both work with and adore), as well as a Pediatric Urologist (not even a part of our hospital). Well be getting ultrasounds every 4 weeks now, with both the MFM and Nephrologists there at those appointments. I feel like we have a plan, and Im only slightly having alarm bells go off. I hope this is what DH had - as DH has normal kidney function as an adult. Does anyone have any experience with kidney issues in particular, or with getting a vague diagnosis like this and having to increase ...
Current treatments for tendon injuries often fail to fully restore joint biomechanics leading to the recurrence of symptoms, and thus resulting in a significant health problem with a relevant social impact worldwide. Cell-based approaches involving the use of stem cells might enable tailoring a successful tendon regeneration outcome. As growth factors (GFs) powerfully regulate the cell biological response, their exogenous addition can further stimulate stem cells into the tenogenic lineage, which might eventually depend on stem cells source. In the present study we investigate the tenogenic differentiation potential of human- amniotic fluid stem cells (hAFSCs) and adipose-derived stem cells (hASCs) with several GFs associated to tendon development and healing; namely, EGF, bFGF, PDGF-BB and TGF-β1. Stem cells response to biochemical stimuli was studied by screening of tendon-related genes (collagen type I, III, decorin, tenascin C and scleraxis) and proteins found in tendon extracellular matrix (ECM)
The objectives of this study were to do inexpensive lamellar body count (LBC) in amniotic fluid, to do statistical analysis to evaluate cutoff values for fetal lung maturity (FLM) and fetal lung immaturity (FLI), to derive a threshold for obtaining a lecithin-to-sphingomyelin (L/S) ratio and phosphatidylglycerol percentage (%PG), and to determine the potential cost savings to the hospital if they use this new method. Testing (LBC, L/S ratio, and %PG) was done on 123 specimens of amniotic fluid. Receiver operating characteristic (ROC) curve, discriminant, linear regression, chi2, and cost analyses were used to evaluate the laboratory and financial parameters. Lamellar body counts of greater than 41,500 (Coulter MAXM: sensitivity, 90.5%; specificity, 87.7%; positive predictive value, 79.2%; negative predictive value, 94.7%) and greater than 32,000 (Coulter Gen.S: sensitivity, 90.5%; specificity, 85.2%; positive predictive value, 76.0%; negative predictive value, 94.5%) were the best threshold for ...
What is fetal lung maturity? Fetal lung maturity measures the amount of surfactant in amniotic fluid. Deficiency causes respiratory distress.
Despite extensive research, the etiology of most preterm births remains unknown. There are significant fetal consequences associated with preterm birth, which include necrotizing enterocolitis, fetal respiratory distress and intra-ventricular hemorrhage. Perinatal mortality is about 44%, 11% and 5% when deliveries occur between 25-28 weeks, 29-32 weeks and 33-34 weeks, respectively. While for many years, it was assumed that the cause of the high morbidity associated with prematurity was the birth of a neonate with a restricted adaptive capacity, it has also been suggested that part of the high perinatal morbidity was the consequence of adverse processes affecting the fetus in utero, rather than of prematurity per se. Intra-amniotic inflammation present in utero early in gestation may trigger the cascade of events leading to preterm birth (i.e. rupture of membranes, cervical ripening, uterine contractions) and provide an intrauterine milieu which is unfavorable or even harmful to the ...
TY - JOUR. T1 - Correlation between amniotic fluid index at admission and intrapartum foetal wellbeing in women with pre-labour rupture of membranes at term. AU - Mallesara, Ashwini. AU - Kushtagi, Pralhad. PY - 2016/6/1. Y1 - 2016/6/1. N2 - Objective: To evaluate measurement of Amniotic Fluid Index (AFI) at admission as a predictor of intrapartum foetal compromise in women with pre-labour rupture of membrane (PROM). Material and Methods: Sonographic record of AFI was made on singleton pregnancies at early and full term admitted in early labour with PROM. The clinical team treating the cases was not aware of the admission AFI values. The labour outcome was studied with respect to the AFI values to find out influence of duration of rupture of membranes (DROM) on intrapartum foetal status, neonatal outcome and infective morbidity. Results: Higher proportion of cases with non-reassuring foetal status (NRFS) was found when admission AFI was less than 5 cm. No baby with low Apgar was born to women ...

Objective: The aim of this study is to assess the intraobserver and interobserver reproducibility of measurement of amniotic fluid index (AFI) and single deepest vertical pool (SDVP), also known as the maximal vertical pocket. Methods: A total of 175 fetuses were evaluated. For each fetus, two observers acquired duplicate sets of AFI and SDVP. Measurement differences were expressed as actual and percentage values. For all comparisons, Bland-Altman plots were used to compare differences, and limits of agreement were calculated. Results: Intraobserver and interobserver agreement remained fairly constant with gestation, both for AFI and SDVP. The intraobserver limits of agreement for AFI were -5.2 to 5 cm or -39% to 37%; whereas for SDVP, these were -2.6 to 2.4 cm or -52% to 48%. The interobserver limits of agreement for AFI measurement were -7.3 to 7.1 cm or -54% to 53% and for SDVP measurement were -2.5 to 2.5 cm or -51% to 52%. Intraobserver coefficient of variation for SDVP was 14% and for AFI was 19%;
Aneuvysion can be added to AFCA for preliminary results (typically available in 48 to 72 hours from the time the sample reached the lab) on the number of chromosome 13, 18, 21, X, and Y present in the fetus..

In recent years, QF-PCR for the detection of common chromosomal trisomies has been introduced as a validated method at a number of cytogenetic centers 13-16. Our study presents results based on the application of QF-PCR for the rapid detection of aneuploidies in chromosomes 13, 18, 21, X and Y on 162 amniotic fluid samples in the Brazilian population.. The QF-PCR results alone were in accordance with 98.05% of all karyotypes excluding cases with chromosomal rearrangements. These results are compatible with other recent reports in the literature. Lildballe et al. 17 analyzed 2,550 samples from chorionic villus sampling (CVS) and amniotic fluid from high-risk pregnancies and reported positive and negative predictive values greater than 99.8%. In this work, different predictive values were reported for each chromosomal abnormality, and even for mosaic trisomies, the detection rate was higher than 99.8%. Rostami et al. 12 reported 4,058 samples analyzed for QR-PCR with a detection rate of 98.59%. ...

When the child is in the uterus it is surrounded by amniotic fluid at this time the child cannot digest and cant breath but is also not adequate able to excrete. The child obtains nutrition by the umbilical cord of the placental structure growing out of the embryo. The placental structure connects the maternal blood vessel to the childs blood vessel, placenta biologically grows out of a developing embryo but also does not grow out of the mother. The blood vessels inside the placenta are the childs placenta including artery and the vein. The placenta grows into the wall of the Uterus of the mother. During pregnancy, the mother continues to eat which means that there will be amino acids, glucose and fats in the blood which will travel through her blood stream, to the placenta and then through to the embryo. The placenta has a large surface area and the barrier is really thin to allow an adequate area for exchange between the mothers blood and the babys blood. The baby, produces molecules back ...

Previously unrecognized and unidentified infections of amniotic fluid may be a significant cause of premature birth, according to a new study.
When a pregnant woman catches Ebola, the fetus and amniotic fluid are flooded with the virus. The ripple effects of these dangerous deliveries could be more catastrophic than Ebola itself.
Needless to say, it is profound how much stress hormones can affect the fetus and the born-human later in life. British researcher Vivette Glover says that the fetus tries to prepare for handling its future life. If the fetus views its life in the womb as unstable and scary, its personality after being born may be unconsciously programmed into a more vigilant, stressed, and jumpy persona in order to handle that prenatal scary life (Glover, 2011). ANOTHER INTERESTING FACT: In the article, Stress pre-birth: How the Fetus is Affected by a Mothers State of Mind, printed in the inaugural issue of the International Journal of Birth and Parent Education; Issue 1, 2013, it was stated that as early as 1937, experiments had been done to show that when saccharin was added to the amniotic fluid, the fetuses swallowed the amniotic fluids more often because of the sweet taste. Then, it was later shown that if bitter fluids were added to the amniotic fluids, the fetuses swallowed or drank of the fluids ...
Results The cells isolated from synovial fluid of patients with RA grew as monolayers in vitro and could be maintained in culture for more than 10 passages. The cells expressed the most important MSC markers (CD44, CD73, CD90 and CD105) with absence of endothelial (CD31, VEGFR2) or hematopoietic cell markers (CD34, CD45, CD69, CD133), respectively. SYF-MSCs were able to differentiate into bone, fat and cartilage tissue in vitro fulfilling the ISCT criteria, and could suppress the proliferation of mitogen activated peripheral blood lymphocytes. Furthermore, SYF-MSCs secreted increased amount of IL-6 after 12 and 24 hrs treatment by LPS (15423.61±9348.61 pg/ml at 12h; 17479.17±3848.63 pg/ml at 24h time points), Poly:IC (15215.28±10834.72 and 24090.28±3626.40 pg/ml), TNFα (7437.5±1168.06 and 11562.5±845.83 pg/ml) and IL-1β (19465.28±2306.94 and 21229.17±12.5 pg/ml) compared to untreated controls (1590.28±1015.28 and 2187.50±640.28 pg/ml), respectively.

Grade 5 VUR is the most severe and requires surgery. We are hopeful that Micah can have his surgery sooner than later so that he can be taken off of the antibiotics. The surgery will entail re-positioning where his ureter enters the bladder and tapering it so fluid can not back up so easy. He may also need the upper part of his ureter tapered where it meets the kidney. We are hopeful that his kidney is still functioning enough to not need it removed, but the tests will tell us more.. Once surgery is complete, he will remain on antibiotics for 3 months and until another set of tests are done. This is unfortunate because Micah gets sick from his antibiotics and we have been fighting acid reflux and vomiting since he was born. He still doesnt sleep through the night, but he has gotten better since we switched his antibiotic to the morning rather than bedtime. We might be able to try a different antibiotic after seeing the nephrologist.. ...

When a rash becomes more intense, there may be a fluid that oozes from it at times. This can sometimes occur without any provocation, or sometimes it can happen after the patient begins to scratch at the rash. This fluid can then crust up, making a hard layer around the edges of the rash or across its surface. This can also add to the pain that can be associated with eczema. Of course, this can affect different sufferers more intensely, and a physician can prescribe a topical medication to help ease the pain and any other side effects ...
