Production of prostaglandin f2alpha and its metabolite by endometrium and yolk sac placenta in late gestation in the tammar wallaby, Macropus Eugenii. (1/9568)

In this study, we investigated production of prostaglandin (PG) F2alpha and its metabolite, PGFM, by uterine tissues from tammar wallabies in late pregnancy. Endometrial explants were prepared from gravid and nongravid uteri of tammars between Day 18 of gestation (primitive streak) and Day 26.5 (term) and were incubated in Ham's F-10 medium supplemented with glutamine and antibiotics for 20 h. PGF2alpha and PGFM in the medium were assayed by specific, validated RIAs. Control tissues (leg muscle) did not produce detectable amounts of either PG. Both gravid and nongravid endometria secreted PGF2alpha, and production increased significantly in both gravid and nongravid uteri towards term. PGFM was produced in small amounts by both gravid and nongravid uteri, and the rate of production did not increase. Neither oxytocin nor dexamethasone stimulated PG production in vitro in any tissue at any stage. Thus, the surge in peripheral plasma PGFM levels seen at parturition may arise from increased uterine PG production, but further study is needed to define what triggers this release.  (+info)

Expression of trophinin, tastin, and bystin by trophoblast and endometrial cells in human placenta. (2/9568)

Trophinin, tastin, and bystin comprise a complex mediating a unique homophilic cell adhesion between trophoblast and endometrial epithelial cells at their respective apical cell surfaces. In this study, we prepared mouse monoclonal antibodies specific to each of these molecules. The expression of these molecules in the human placenta was examined immunohistochemically using the antibodies. In placenta from the 6th week of pregnancy, trophinin and bystin were found in the cytoplasm of the syncytiotrophoblast in the chorionic villi, and in endometrial decidual cells at the utero placental interface. Tastin was exclusively present on the apical side of the syncytiotrophoblast. Tissue sections were also examined by in situ hybridization using RNA probes specific to each of these molecules. This analysis showed that trophoblast and endometrial epithelial cells at the utero placental interface express trophinin, tastin, and bystin. In wk 10 placenta, trophinin and bystin were found in the intravillous cytotrophoblast, while tastin was not found in the villi. After wk 10, levels of all three proteins decreased and then disappeared from placental villi.  (+info)

Delay of preterm delivery in sheep by omega-3 long-chain polyunsaturates. (3/9568)

A positive correlation has been shown between dietary intake of long-chain omega-3 fatty acids in late pregnancy and gestation length in pregnant women and experimental animals. To determine whether omega-3 fatty acids have an effect on preterm labor in sheep, a fish oil concentrate emulsion was continuously infused to six pregnant ewes from 124 days gestational age. At 125 days, betamethasone was administered to the fetus to produce preterm labor. Both the onset of labor and the time of delivery were delayed by the fish oil emulsion. Two of the omega-3-infused ewes reverted from contractions to nonlabor, an effect never previously observed for experimental glucocorticoid-induced preterm labor in sheep. Maternal plasma estradiol and maternal and fetal prostaglandin E2 rose in control ewes but not in those infused with omega-3 fatty acid. The ability of omega-3 fatty acids to delay premature delivery in sheep indicates their possible use as tocolytics in humans. Premature labor is the major cause of neonatal death and long-term disability, and these studies present information that may lead to a novel therapeutic regimen for the prevention of preterm delivery in human pregnancy.  (+info)

Luteinizing hormone inhibits conversion of pregnenolone to progesterone in luteal cells from rats on day 19 of pregnancy. (4/9568)

We have previously reported that intrabursal ovarian administration of LH at the end of pregnancy in rats induces a decrease in luteal progesterone (P4) synthesis and an increase in P4 metabolism. However, whether this local luteolytic effect of LH is exerted directly on luteal cells or on other structures, such as follicular or stromal cells, to modify luteal function is unknown. The aim of the present study was to determine the effect of LH on isolated luteal cells obtained on Day 19 of pregnancy. Incubation of luteal cells with 1, 10, 100, or 1000 ng/ml of ovine LH (oLH) for 6 h did not modify basal P4 production. The addition to the culture medium of 22(R)-hydroxycholesterol (22R-HC, 10 microgram/ml), a membrane-permeable P4 precursor, or pregnenolone (10(-2) microM) induced a significant increase in P4 accumulation in the medium in relation to the control value. When luteal cells were preincubated for 2 h with oLH, a significant (p < 0.01) reduction in the 22R-HC- or pregnenolone-stimulated P4 accumulation was observed. Incubation of luteal cells with dibutyryl cAMP (1 mM, a cAMP analogue) plus isobutylmethylxanthine (1 mM, a phosphodiesterase inhibitor) also inhibited pregnenolone-stimulated P4 accumulation. Incubation with an inositol triphosphate synthesis inhibitor, neomycin (1 mM), or an inhibitor of intracellular Ca2+ mobilization, (8,9-N, N-diethylamino)octyl-3,4,5-trimethoxybenzoate (1 mM), did not prevent the decrease in pregnenolone-stimulated P4 secretion induced by oLH. It was concluded that the luteolytic action of LH in late pregnancy is due, at least in part, to a direct action on the luteal cells and that an increase in intracellular cAMP level might mediate this effect.  (+info)

Outcome of pregnancy in women with congenital shunt lesions. (5/9568)

OBJECTIVE: To evaluate the outcome of pregnancy in women with congenital shunt lesions. SETTING: Retrospective study in a tertiary care centre. METHODS: Pregnancy history was obtained by a standardised questionnaire and medical records were reviewed. PATIENTS: 175 women were identified, at a mean (SD) age of 42 (14) years. Pregnancies occurred in 126 women: 50 with an atrial septal defect, 22 with a ventricular septal defect, 22 with an atrioventricular septal defect, 19 with tetralogy of Fallot, and 13 with other complex shunt lesions. RESULTS: 309 pregnancies were reported by 126 woman (2.5 (1.6) pregnancies per woman). The shortening fraction of the systemic ventricle was 40 (8)%, and 98% were in New York Heart Association class I-II at last follow up. Spontaneous abortions occurred in 17% of pregnancies (abortion rate, 0.4 (0.9) per woman). Gestational age of the 241 newborn infants was 8.8 (0.8) months. There were no maternal deaths related to pregnancy. Pre-eclampsia and embolic events were observed in 1.3% and 0.6%, respectively of all pregnancies. Women with complex shunt lesions more often underwent caesarean section (70% v 15-30%, p = 0.005) and gave birth to smaller babies for equivalent gestation (2577 (671) g v 3016 (572) to 3207 (610) g, p < 0.05). The recurrence risk of congenital heart disease was 2.5%. CONCLUSIONS: The outcome of pregnancy is favourable in women with congenital shunt lesions if their functional class and their systolic ventricular function are good. Such patients can be reassured.  (+info)

Expression of neurotrophins and their receptors in human bone marrow. (6/9568)

The expression of neurotrophins and their receptors, the low-affinity nerve growth factor receptor (p75LNGFR) and the Trk receptors (TrkA, TrkB, and TrkC), was investigated in human bone marrow from 16 weeks fetal age to adulthood. Using reverse transcription-polymerase chain reaction, all transcripts encoding for catalytic and truncated human TrkB or TrkC receptors were detected together with trkAI transcripts, whereas trkAII transcripts were found only in control nerve tissues. Transcripts for the homologue of the rat truncated TrkC(ic113) receptor were identified for the first time in human tissue. Stromal adventitial reticular cells were found immunoreactive for all neutrophin receptors. In contrast, hematopoietic cell types were not immunoreactive for p75LNGFR but showed immunoreactivity for one or several Trk receptors. TrkA immunoreactivity was found in immature erythroblasts. Catalytic TrkB immunoreactivity was observed in eosinophilic metamyelocytes and polymorphonuclear cells. Truncated TrkB immunoreactivity was found in erythroblasts and megacaryocytes. Immunoreactivity for both catalytic and truncated TrkC receptor was observed in promyelocytes, myelocytes, some polymorphonuclear cells and megacaryocytes. Neutrophin transcript levels appeared higher at fetal than at adult stages, no variation in Trk family transcript levels was observed. The local expression of neurotrophin genes suggests a wide range of paracrine and/or autocrine mode of action through their corresponding receptors within the bone marrow.  (+info)

Maternal adrenocortical hormones maintain the early development of pancreatic B cells in the fetal rat. (7/9568)

To investigate the effect of maternal adrenocortical hormones on the development of fetal pancreatic islet cells, pregnant rats were adrenalectomised on d 6 of gestation. On d 12-16 the growth patterns of fetal insulin-producing B cells, glucagon-producing A cells, and somatostatin-producing D cells were observed histometrically. Maternal adrenalectomy resulted in growth retardation of fetal B cells on d 12-15. Maternal corticosterone therapy prevented this retardation. Maternal adrenalectomy, however, did not affect the developmental patterns of A and D cells. By Western blotting and immunohistochemistry, glucocorticoid receptors were demonstrated to be present in the islet cells from d 12 to d 15. These results suggest that maternal adrenocortical hormones, glucocorticoids in particular, maintain the early development of fetal pancreatic B cells through their specific intracellular glucocorticoid receptor.  (+info)

Developmental changes in mucosubstances revealed by immunostaining with antimucus monoclonal antibodies and lectin staining in the epithelium lining the segment from gizzard to duodenum of the chick embryo. (8/9568)

The mucosubstances in the epithelium lining the segment from gizzard to duodenum during development of the chick embryo was studied histochemically using monoclonal antibodies against gizzard mucus and lectins, with attention to the regional differentiation of the epithelium in this segment. The anterior limit of epithelial CdxA mRNA expression detected by in situ hybridisation, which served as the position of the gizzard-duodenal boundary, was clearly found from d 3. Granules positive for some antibodies or lectins were found in the region ranging from the posterior part of the gizzard to the duodenum at d 3, which was followed by an increase in the number of granules and a gradual enlargement of the granule-positive area to the anterior part of the gizzard over 4-6 d. From d 4, the epithelia of the gizzard body and of the pyloric or duodenal region came to be differently stained with some antibodies or lectins. From d 10, each region showed a specific pattern of staining. The epithelia of the gizzard body and pyloric region contained abundant mucus granules with a different staining pattern. In the duodenum the number of stained granules was low except in occasional goblet cells. Thus the epithelia of the gizzard body, pyloric region and duodenum may produce different mucosubstances and the regional differentiation in these epithelia may start at rather early stages soon after the formation of digestive tube.  (+info)

TY - JOUR. T1 - Comparisons of infant mortality using a percentile-based method of standardization for birthweight or gestational age. AU - Hertz-Picciotto, Irva. AU - Din-Dzietham, Rebeca. PY - 1998/1. Y1 - 1998/1. N2 - Comparisons of infant, perinatal, or neonatal mortality across populations with different birthweight or gestational age distributions are problematic. Summary measures with adjustment for birthweight or gestational age frequently are invalid or lack interpretability. We propose a percentile- based method of standardization for comparing infant, perinatal, or neonatal mortality across populations that have different distributions of birthweight and/or gestational age. The underlying concept is a simple one: comparable health for two population groups will be expressed as equal rates of disease or mortality at equal quantiles in the two distributions of birthweight or gestational age. We describe this method mathematically and present an example comparing mortality rates for ...
We used a whole genome approach to identify major functional gene categories (including xenobiotic transporters and metabolizing enzymes) whose expression depends on gestational age. STUDY DESIGN: We compared gene expression profiles of 1st (45-59 days) and 2nd trimester (109-115 days), and C-section term placentae. RESULTS: In 1st trimester placentae, genes related to cell cycle, DNA, aminoacids and carbohydrate metabolism were significantly overrepresented, while genes related to signal transduction were downregulated. In the organism defense category, we identified genes involved in chemical response, metabolism, and transport. Analysis of signal transduction pathways suggested, and subsequently confirmed independently, that the Wnt pathway was regulated by gestational age. CONCLUSIONS: Our study will serve as a reference database to gain insight into the regulation of gene expression in the developing placentae and, thus, allow comparisons with placentae from complicated pregnancies such as those
Background:Preterm birth is a major global health challenge, the leading cause of death in children under 5 years of age, and a key measure of a populations general health and nutritional status. Current clinical methods of estimating fetal gestational age are often inaccurate. For example, between 20 and 30 weeks of gestation, the width of the 95% prediction interval around the actual gestational age is estimated to be 18-36 days, even when the best ultrasound estimates are used. The aims of this study are to improve estimates of fetal gestational age and provide personalised predictions of future growth. Methods:Using ultrasound-derived, fetal biometric data, we developed a machine learning approach to accurately estimate gestational age. The accuracy of the method is determined by reference to exactly known facts pertaining to each fetus-specifically, intervals between ultrasound visits-rather than the date of the mothers last menstrual period. The data stem from a sample of healthy, well-nourished

We assessed anthropometric status, breastfeeding duration, morbidity, and mortality outcomes during the first four years of life according to gestational age, in three population-based birth cohorts in the city of Pelotas, Southern Brazil. Total breastfeeding duration, neonatal mortality, infant morbidity and mortality, and anthropometric measures taken at 12 and 48 months were evaluated in children of different gestational ages born in 1982, 1993 and 2004 in Southern Brazil. Babies born |34 weeks of gestation and those born between 34-36 weeks presented increased morbidity and mortality, were breastfed for shorter periods, and were more likely to be undernourished at 12 months of life, in comparison with the 39-41 weeks group. Children born with 37 weeks were more than twice as likely to die in the first year of life, and were also at increased risk of hospitalization and underweight at 12 months of life. Post-term infants presented an increased risk of neonatal mortality. The increased risks of

The postnatal gestational age estimation model previously published by our group included 249 700 infants born between April 2007 and March 2009. The details of the original model have been described previously.9 Briefly, infants who were identified as positive for any disorder screened for by NSO were excluded, as were infants with unsatisfactory samples, and missing gestational age and birth weight. Because complete metabolite profiles were required to score new observations, infants with missing analyte data or other covariates including gestational age, were excluded from this validation exercise. The infants excluded due to missing covariates constituted ,5% of the cohort. Gestational age was based on best obstetrical estimate (last menstrual period, dating ultrasound or a combination). It is to be noted that ,99% of women in Ontario receive at least one ultrasound during the course of pregnancy.10 The data were randomly partitioned into model development (50%), validation (25%) and test ...
Large for gestational age (LGA) is a term used to describe babies who are born weighing more than the usual amount for the number of weeks of pregnancy. LGA babies have birthweights greater than the 90th percentile for their gestational age, meaning that they weigh more than 90 percent of all babies of the same gestational age.. The average baby weighs about 7 pounds at birth. About 8 percent of all babies weigh more than 4,000 grams (8 pounds, 13 ounces). Rarely do babies weigh over 10 pounds.. Although most LGA babies are born at term (37 to 41 weeks of pregnancy), a few premature babies may be LGA.. ...

BACKGROUND: Perinatal decision-making affects outcomes for extremely preterm babies (22-26 weeks gestational age (GA)): more active units have improved survival without increased morbidity. We hypothesised such units may gain skills and expertise meaning babies at higher gestational ages have better outcomes than if they were born elsewhere. We examined mortality and morbidity outcomes at age two for babies born at 27-28 weeks GA in relation to the intensity of perinatal care provided to extremely preterm babies. METHODS: Fetuses from the 2011 French national prospective EPIPAGE-2 cohort, alive at maternal admission to a level 3 hospital and delivered at 27-28 weeks GA, were included. Morbidity-free survival (survival without sensorimotor (blindness, deafness or cerebral palsy) disability) and overall survival at age two were examined. Sensorimotor disability and Ages and Stages Questionnaire (ASQ) result below threshold among survivors were secondary outcomes. Perinatal care intensity level
Based on gestational age at diagnosis and/or delivery, pre-eclampsia (PE) is commonly divided into early-onset (,34 weeks) and late-onset (,= 34 weeks) forms. Recently, the distinction between placental and maternal causation has been proposed, with placental cases being more frequently associated with early-onset and intrauterine growth restriction. To test whether molecular placental pathology varies according to clinical presentation, we investigated stress-signalling pathways, including unfolded protein response (UPR) pathways, MAPK stress pathways, heat-shock proteins and AMPK.. in placentae delivered by caesarean section for clinical indications at different gestational ages. Controls included second-trimester, pre-term and normal-term placentae. BeWo cells were used to investigate how these pathways react to different severities of hypoxia-reoxygenation (H/R) and pro-inflammatory cytokines. Activation of placental UPR and stress-response pathways, including P-IRE1 alpha, ATF6, ...
The correct identification of the gestational age at birth, when clinical parameters and ultrasound are inconclusive or do not exist, can help the health team to make decisions for the best care with the baby. For this, we developed the Preemie-Test, an innovative technology that evaluates the maturity of the skin through its reflection in light, estimating the gestational age at birth. Two multicenter clinical trials are underway to validate the accuracy of the test in the detection of the preterm newborn ...
Large for gestational age is used to describe newborn babies who weigh more than the usual amount for the number of weeks of pregnancy. Babies are called large for gestational age if they weigh more than 9 in 10 babies of the same gestational age.
Assigning size is a way to measure and monitor the growth of the infant throughout the pregnancy as well as at the time of birth. The measurement is calculated based on the estimated gestational age (how many weeks the mother was pregnant) in comparison to what is considered normal height, weight, head size, and developmental level for a child of the same gestational age and gender. Graphs are available showing the upper and lower normal limits for different gestational ages from the mid-20s through 42 weeks of gestation. An appropriate for gestational age full-term infant is heavier than 2500 grams (about 5.5 lbs.) and lighter than about 4000 grams (about 8.75 lbs.). ...
To establish levels of mediators of inflammation in cord blood and postnatal serum from extremely low gestational age newborns (ELGANs, | or =28 weeks), we measured sixteen markers of inflammation by recycling immunoaffinity chromatography in 15 ELGANs who had serum sampled at days 2-5. Median levels of IL-1, IL-6, IL-8, IL-11, IL-13, TNF-alpha, G-CSF, M-CSF, GM-CSF, MIP-1alpha, and RANTES were considerably higher than published values of these inflammatory mediators from term newborns. In three of eight ELGANS who had serial measurements taken, levels of IL-1, IL-6, IL-8, IL-11, TNF-alpha, G-CSF, and MIP-1alpha declined from initially very high levels to reach an apparent baseline towards the end of the first postnatal week. In these same three infants, GM-CSF and TGF-beta1 levels increased continuously during the first week. In the other five ELGANs, no consistent changes were observed. We speculate, that in some ELGANs, a fetal systemic inflammatory response is characterized by an antenatal wave of
INTRODUCTION: Current classification of hypertensive disorders of pregnancy (HDP) is mostly based on temporal classification differentiating HDP according to early and late onset of the disease. However, epidemiological and clinical data suggest that there are two different clinical phenotypes of HDP that coexist at any gestational age: HDP associated to intrauterine growth restriction (HDP-IUGR) and HDP associated to appropriate for gestational age fetal growth (HDP-AGAf). The aim of the study was to evaluate the association of first trimester uterine arteries (UtA) by Doppler velocimetry, and maternal risk factors with HDP according to two different classifications: one based on gestational age at delivery (early- and late-HDP), and one based on longitudinal ultrasound evaluation of fetal growth (HDP-IUGR and HDP-AGAf), independently of the gestational age ...
Vascular endothelial processes are greatly affected by endothelial progenitor cells (EPC) circulating in peripheral blood. This unique progeny has been shown to play an important role in vascular endothelial maintenance and healing processes as well as in pathological formation of new blood vessels (neovascularisation) specifically in diseases such as diabetic retinopathy and retinopathy of prematurity.. To address the role of EPC in premature infants we measured gene expression of endothelial-specific and progenitor-associated genes (AC133, TIE-2, FLK-1 (VEGFR2), SCL/TAL1 and VEGF) by quantitative reverse transcription PCR in the peripheral blood of preterm infants, born between 24 and 34 weeks gestational age. Transcript levels were assessed in three consecutive time points-on day 3-5 of life, on day 10-15 and at one month of age.. The mRNA expression level of EPC markers did not significantly change between different gestational age groups or birth weights. Elevated levels of TIE-2 correlated ...
Small for gestational age (SGA) embryos are those who are smaller in size than normal for the gestational age, most commonly defined as a weight below the 10th percentile for the gestational age.[
Small for gestational age is a term used to describe babies that are smaller than usual for the number of weeks of pregnancy. These babies have birth weight below the 10th percentile. This means they are smaller than many other babies of the same gestational age.

TY - JOUR. T1 - Laboratory tests and measurements in children born small for gestational age (SGA). AU - Geremia, Caterina. AU - Cianfarani, Stefano. PY - 2006/2. Y1 - 2006/2. N2 - Children born small for gestational age are at high risk of developing insulin resistance, type 2 diabetes, hyperlipidemia, hypertension and cardiovascular disease in adulthood. In addition, approximately 10% of SGA children do not achieve a normal adult height. Studies performed in SGA children to evaluate markers of metabolic disease in prepubertal, pubertal and adolescent subjects, indicate a higher prevalence of subtle endocrine and metabolic abnormalities that may precede the onset of overt disease in adulthood. At present, however, there are no conclusive data supporting the need of systematic close monitoring of GH-IGF, hypothalamus-pituitary-adrenal and hypothalamus-pituitary-gonadal axes, as well as insulin sensitivity, glucose homeostasis, and lipid metabolism. Monitoring of metabolic parameters should ...
Growth characteristics of 15 full-term infants, selected because of weights more than 2 SD below the mean for gestational age, are described. The response to an intravenous injection of glucose was utilized to measure the insulin response of the infants at 6 months.. Infants small for gestational age grow at a faster rate than appropriate-for-age infants during the first six months of life. There was a positive correlation between the growth velocity of the period and insulin release and a negative correlation between growth velocity and birth length. There was no correlation between these variables and increases in weight during the same period.. Growth velocity during catch-up growth is related to the degree of preceding retardation but insulin may play a permissive role.. ...

In a large cohort of extremely preterm infants born at ,26 weeks gestational age, we found that 50% to 60% of survivors born at 22 and 23 weeks gestational age and ∼30% of survivors at 24 and 25 weeks gestational age had disability at 3 years of age in terms of mental and psychomotor development. On the other hand, nearly half of the infants born even at 22 or 23 weeks, and who had survived to 3 years of age, were unimpaired or minimally impaired, although these proportions were lower than those for infants born at 24 or 25 weeks. The incidence of death or NDI was clearly related to gestational weeks, consistent with many previous studies.3,5-21 Among the survivors, however, the incidence of NDI for those born at 22 weeks was nearly equal to that for those born at 23 weeks. This result was probably affected by the high mortality for 22 weeks, meaning that the most severe cases born at 22 weeks died early in life. In addition, the proportion of NDI at 22 weeks should be interpreted with ...
Developmental Care is a term used by many people and can mean many different things. In the book Hold your Prem, I use the term Developmental Care to mean a gentle method of caring for all babies, especially for the premature baby, which will support the healthy development of body, brain and emotions by minimizing stress, and so reducing problems for the baby in the future. The DVD Hold Your Prem shows practically how to do this.. Premature babies are very small and very sensitive; they sense everything! They are also individual and will respond differently to different sensations. There are differences between prems born at different gestational ages.. Modern technology can keep smaller and younger babies alive, but we want these babies to have the best quality of life as well, so we have to treat them extra gently. The babys brain is the organ that is developing most in the last 10-12 weeks of pregnancy. For premature babies this development has to be outside the womb, not inside mother ...

Health risks associated with ET birth are increasingly reported but remain poorly understood. The present study, showing lower levels of CRF through adolescence into young adulthood in individuals who were born ET versus FT or LT, adds important information to this emerging field. Indeed, to the best of our knowledge, this is the first study that has examined variations in the levels of CRF across different gestational lengths within the at‐term range; it is also the first to have characterized these across different critical age periods in the life course.. Explanations for the protective and lifelong effects that longer gestational age seems to have on CRF align with the hypothesis that exposure of babies to the postnatal environment while still developmentally plastic may increase susceptibility to health impairments.51 Earlier births may interrupt normal development and lead to permanent changes of tissues and organs, such as fewer alveoli, lower capillary density, and a smaller vascular ...
A baby who is smaller than average during pregnancy is called small for gestational age. Some babies are small because their parents are small. But most SGA babies are small because of growth problems that happen in pregnancy.
During the last third of gestation, fetal sheep underwent exponential growth of heart and body (Fig. 2). LV-to-heart mass ratio did not change with advancing gestational age, but that of the RV to heart increased slightly during the same period (Table 1 and Fig. 3).. Lengths and widths of myocytes from the fetal ventricles over the last third of gestation are shown in Fig. 4. The lengths of binucleated myocytes from both ventricles and the lengths of RV mononucleated myocytes did not increase significantly with gestational age (Table 1). LV mononucleated myocytes significantly increased in length but only slightly. Binucleated and mononucleated myocytes from both ventricular free walls increased in width during this period. Accordingly, the ratio of lengths to widths decreased with advancing age in mononucleated and binucleated myocytes of both ventricles (Table 1).. Myocyte volumes, calculated from myocyte dimensions and a correction factor, increased with advancing gestational age (Fig. 5). ...

Assessing a babys physical maturity is an important part of care. Maturity assessment is helpful in meeting a babys needs if the dates of a pregnancy are uncertain. For example, a very small baby may actually be more mature than it appears by size, and may need different care than a premature baby.. An examination called the Dubowitz/Ballard Examination for Gestational Age is often used. A babys gestational age often can be closely estimated using this examination. The Dubowitz/Ballard Examination evaluates a babys appearance, skin texture, motor function, and reflexes. The physical maturity part of the examination is done in the first two hours of birth. The neuromuscular maturity examination is completed within 24 hours after delivery.. ...
NOTE: In July of 1997 Janssen - Ortho Inc (Canada) issued a letter stating Prepulsid is contraindicated in prematurely born infants (born at a gestational age of less than 36 weeks), from 0 through three months after the delivery date.(128) This follows case reports of prolongation of the QT interval in infants and pediatric patients. (129 - 132) In addition, a prospective study of 49 neonates demonstrated an increased QT interval (above an arbitrary interval of 0.45, n=7). (133) The prolonged QT interval was inversely correlated to birth weight and gestational age and was most frequent in infants < 33 weeks gestation ...
Both my children were born at 38 weeks gestational age and were at a normal developmental age. My babies were about 7 pounds and 6 pounds each. My sister, a type 1 diabetic, went full term with both the babies were close to 9 pounds-they are bigger children to this day-their father is a tall man. Her babies were healthy and at a normal developmental age. I was told that a diabetics placenta begins to die or lose its nutrients at 38 weeks and that is when the babies were born. I have no idea what the most recent studies are about, maybe the information has changed. My youngest child is 11 and that is the last I ever thought about having children!

Carnegie stages are named after the famous US Institute which began collecting and classifying embryos in the early 1900s. The human embryonic period proper is divided into 23 Carnegie stages and covers most of the first trimester of human development. Carnegie stages are based on the external and/or internal morphological development of the embryo, and are not directly dependent on either age or size. Criteria beyond morphological features include age in days, number of somites present, and embryonic length. Similar staging criteria can be applied to embryos from other species. ...

Background: Both preterm and post-term births have been associated with neonatal morbidity and mortality, including adverse impact on neurodevelopment. Important neural maturational processes take place during sleep in newborns, but findings on gestational duration and sleep in early childhood are contradictory and often derive from small clinical samples. We studied the association of gestational age at birth with sleep duration in early childhood in three population-based cohorts. Methods: Gestational age at birth and sleep duration were assessed in three population-based cohort studies in The Netherlands (n = 6471), Singapore (n = 862), and Canada (n = 583). Gestational age at birth was assessed using ultrasound in pregnancy in combination with date of birth, and caregivers repeatedly reported on child sleep duration at three, six, 24, and 36 months of age. Generalized estimating equations were used, which were adjusted for confounders, and findings were pooled in a meta-analysis. Results: ...

Fetal growth restriction is one of the greatest risk factors for stillbirth. This pilot cohort study examined whether rapid placental volume (PlaV) calculation at 11 to 13 + 6 weeks can predict the small for gestational age (cSGA) baby. Women with singleton pregnancies were recruited (N = 145), a static three-dimensional (3-D) volume was captured, and the placental volume was computed using a semi-automated technique. Regression analysis explored the relationships between customized birth weight, placental quotient (PQ), standardized placental volume (sPlaV), and other predictors of SGA (including pregnancy-associated protein and uterine artery pulsatility index (PI). The results were examined using receiver-operating characteristic (ROC) curve analysis in the total population and then in the 2 subgroups whose members were classified as low risk or high risk at booking. Both PQ and sPlaV were significantly different for cSGA pregnancies compared to appropriate for gestational age (AGA) babies (p = 0.003
Background: There is an assumption that fetus with restricted growth with an inappropriate intrauterine environment lies under stress. Although small-for-gestational-age (SGA) infants have higher mortality, difference in the outcome of SGA and appropriate-for-gestational-age (AGA) infants regarding respiratory morbidity is controversial. It seems that respiratory morbidities in SGA neonates is different from neonates with AGA. In this study, we intend to compare the mortality and respiratory morbidity rates between the preterm small for gestational age (SGA) and appropriate for age (AGA) neonates of less than 34 weeks of gestation. Methods: This analytical cross-sectional study was conducted on 498 preterm neonates with gestational age of , 34 weeks, admitted to the Neonatal Intensive Care Unit. These neonates were categorized into two groups of SGA (n=210) and AGA (n=286). The data analysis was performed, using Students t-test and Mann-Whitney U test for parametric variables and Chi-square and ...
Large for gestational age (LGA) is an indication of high prenatal growth rate. LGA is often defined as a weight, length, or head circumference that lies above the 90th percentile for that gestational age. However, it has been suggested that the definition be restricted to infants with birth weights greater than the 97th percentile (2 standard deviations above the mean) as this more accurately describes infants who are at greatest risk for perinatal morbidity and mortality. Macrosomia, which literally means long body, is sometimes confused with LGA. Some experts consider a baby to be big when it weighs more than 8 pounds 13 ounces (4,000 g) at birth, and others say a baby is big if it weighs more than 9 pounds 15 ounces (4,500 g). A baby is also called large for gestational age if its weight is greater than the 90th percentile at birth. LGA and macrosomia cannot be diagnosed until after birth, as it is impossible to accurately estimate the size and weight of a child in the womb. Babies that ...
The number of live born babies at or after term (from 37 completed weeks gestational age) with an Apgar score of less than 7 at 5 minutes, divided by the number of live born babies born at or after term (from 37 completed weeks gestational age), and multiplied by 100.. A birth is defined as an event in which a baby comes out of the uterus after a pregnancy of at least 20 weeks gestation or weighing 400 grams or more. If the baby is alive the birth is a live birth. If the baby is not alive the birth is a stillbirth.. Gestational age is a clinical measure of the duration of the pregnancy. For the National Perinatal Data Collection gestational age is reported as completed weeks. Term is defined as gestational age between 37 and 41 weeks.. Births included are live born babies born at or after term.. Births excluded are stillbirths and babies born before term (before 37 weeks). ...
In infants born prematurely, researchers at Washington University School of Medicine in St. Louis have found that the population of bacteria in babies gastrointestinal tracts may depend more on their biological makeup and gestational age at birth than on environmental factors. The scientists discovered that bacterial communities assemble in an orderly, choreographed progression, with the pace of that assembly slowest in infants born most prematurely.

BACKGROUND: Preterm birth and shorter duration of pregnancy are associated with increased morbidity in neonatal and later life. As the epigenome is known to have an important role during fetal development, we investigated associations between gestational age and blood DNA methylation in children. METHODS: We performed meta-analysis of Illuminas HumanMethylation450-array associations between gestational age and cord blood DNA methylation in 3648 newborns from 17 cohorts without common pregnancy complications, induced delivery or caesarean section. We also explored associations of gestational age with DNA methylation measured at 4-18 years in additional pediatric cohorts. Follow-up analyses of DNA methylation and gene expression correlations were performed in cord blood. DNA methylation profiles were also explored in tissues relevant for gestational age health effects: fetal brain and lung. RESULTS: We identified 8899 CpGs in cord blood that were associated with gestational age (range 27-42 ...

Knowledge of gestational age at the time of birth is important for distinguishing the preterm from the small-for-gestational age (SGA) infant, whose medical needs and expectations for achieving significant development milestones may be different. Reliable gestational age estimates are also useful for quantifying population burdens of preterm birth, which can facilitate appropriate allocation of resources to hospital centres and regions of greatest need. In many low-income and middle-income countries, maternal access to prenatal care, in particular to ultrasound dating services, is limited and imprecise measures, such as last menstrual period, fundal height, or examination of the newborn are relied on for gestational age estimation.1-3 Given that gestational dating based on knowledge of last menstrual period is frequently unreliable4-6 and postnatal physical examinations are subject to variability based on subjective scoring and poor performance in extreme preterm and SGA infants,7 8 new methods ...
Estimates of preterm birth are calculated based on gestational age information reported on the birth certificate. The primary measure used to determine the gestational age of the newborn is the interval between the first day of the mothers last normal menstrual period (LMP) and the date of birth, and presented as number of weeks. It is subject to error for several reasons, including imperfect maternal recall or misidentification of the LMP because of postconception bleeding, delayed ovulation, or intervening early miscarriage. These data are edited for LMP-based gestational ages that are clearly inconsistent with the infants plurality and birthweight, but reporting problems for this item persist and may occur more frequently among some subpopulations and among births with shorter gestations.. The 1989 revision of the U.S. Standard Certificate of Live Birth includes an item, clinical estimate of gestation and the 2003 revision of the birth certificate includes a comparable item Obstetric ...

The study was performed on pregnant women with a gestational age of 26-32 weeks of pregnancy, who had been admitted to the hospital with a confirmed diagnosis of premature rupture of membranes. In all eligible women, ultrasounds were performed for the evaluation of amniotic fluid index. Then, the women were divided into two groups according to amniotic fluid index of ≥5 cm and ,5 cm. These women were followed and monitored up to delivery. The women of the two groups did not have significant difference between them according to age, gestational age at the time of ruptured membrane, body mass index, gravidity, parity, gestational age at delivery and route of delivery ...
Surprises can be exciting. If you are the parent of a preterm infant, then you are well aware of the initial rush of emotions that this surprise arrival brought you.. But, once your bundle of joy has left the hospital and settled in at home, you may not realize that his/her prematurity needs to remain a consideration beyond the hospital walls. In reality, even if your baby was born only a week or two ahead of schedule and looks just like a full-term infant, you should understand that he/she may have special vulnerabilities requiring a little more TLC. While the term preemie often connotes very preterm (born before 32 weeks gestation, or weeks of growing, in the mothers womb) or moderately preterm (born between 32 and 34 weeks gestational age), most premature babies are actually born between 34 and 36 weeks gestational age and are considered late preterm. The health risks associated with these late-preterm babies are often overlooked or misunderstood by parents because their child ...
Plasma proteomics reveals gestational age-specific responses to mechanical ventilation and identifies the mechanistic pathways that initiate preterm lung injury
We evaluated a simple, weight-based, extended-interval dosing (EID) gentamicin protocol specifically in neonates with gestational age ≤ 33 weeks, and its impact on sub-therapeutic peaks, elevated troughs, and simplification of dosing and monitoring as compared to a weight-based, multiple daily dose (MDD) protocol. Methodology. This study evaluated all infants with GA ≤ 33 weeks receiving gentamicin 1-year before EID protocol implementation in Jan 2002, and 1-year after. The MDD protocol used 2.5mg/kg every 8, 12, 18, or 24 hrs based on weight and age groupings. The EID protocol uses 3mg/kg q24 hours if weight , 1500gm and 4mg/kg if weight ≤ 1500gm. Desired trough was ≤ 2.0 mcg/ml and peak was 5 - 12 mcg/ml. Results. Characteristics were similar for the 123 MDD and 98 EID patients reviewed. The percentage of patients with at least 1 sub-therapeutic peak was lower with EID (7% vs. 20%, p,0.001); however the percentage with at least 1 elevated trough was similar (15% vs. 19%, p=0.219). ...

While some studies have found no significant difference in the rate of induction between women who have a first trimester scan and women who have both a first and second trimester scan .. The analysis was therefore unable to conclusively determine whether the benefits of the recommendation would be likely to outweigh the costs.. Diagnostic ultrasound is a sophisticated electronic technology, which uses pulses of high frequency sound to produce an image.. This imaging enables measurement of the fetus and estimation of the gestational age.. Ultrasound examination in the first trimester allows accurate assessment of gestational age, and identifies and allows for appropriate care of women with multiple pregnancies.. Methods used to assess gestational age include known date of ovulation, date of the last menstrual period () and diagnostic ultrasound.. The study found that the earlier the ultrasound assessment in pregnancy (preferably between 10 and 12 weeks), the more accurate the prediction of date ...

WHAT DOES THE TERM SGA (SMALL FOR GESTATIONAL AGE) MEAN?. SGA (small for gestational age) generally describes any infant whose birth weight and/or birth length was less than the 3rd percentile, adjusted for prematurity (gestational age). Between 3% and 10% of live births each year are diagnosed as SGA. In addition, when ultrasound evidence demonstrated poor fetal growth while in-utero, an infant may also be described as IUGR, which means the fetus experienced intrauterine growth restriction.. The factors behind why an infant is born SGA can be quite complex. The factors include fetal (such as genetic syndrome), maternal (such as substance use or infection), placental, and/or demographic (mothers age, income level - these are both rare).. But setting aside these possible causes, 9 out of 10 infants born SGA do experience catch-up growth by the age of 2 years, and usually by 6 months of age. Catch-up growth typically means that the childs length curve moves upward, crossing the 3rd ...
Dale Carnegie How To Win Friends And Influence People Стр 10 - How to Win Friends and Influence People by Dale Carnegie. Dale Carnegie wrote this book in 1937. The publisher originally only printed 5,000 copies. It was an immediate best seller and went on to sell over 30 million copies. I’ve always had a very strong allergy to the idea of “networking” and trying to “win friends” and/or “influence people” so this one never quite resonated but

The study was conducted in Scotland which, at the moment, is still part of the United Kingdom (UK). For those unfamiliar with UK healthcare system, we have the National Health Service (NHS) which is paid for through direct taxation and currently means that all citizens, irrespective of income or status, have a right to free healthcare at the point of need. From cradle to grave, each person has a unique NHS number, which alongside some quite copious amounts of note-taking, provides an impressive bank of health information about a person. Health services often overlap with other areas such as social and educational services (most of the time) which can form quite a detailed picture of a citizen as evidence by the Child Health Profiles reports for example which are accessible to all and provide a wealth of information. Having experienced first-hand how much information is gathered at birth and the early years, I can vouch for this being a pretty good system ...
Hospital birth records were sought for 104 men from a pool of male army conscripts with normal or high blood pressure when measured at 28 years of age. Of 77 men whose birth weight and date of the mothers last menstrual period before the pregnancy could be found, 25 had a resting diastolic blood pressure of ≥90 mm Hg. In 11 of these compared with nine of the 52 men with normal diastolic pressures their birth weights in relation to gestational age had been below the mean and 1 SD of a comparable Swedish population. The risk of increased diastolic blood pressure in early adult life was significantly higher among men who had been growth retarded at birth than among those whose birth weight had been appropriate for gestational age (odds ratio 3·63; 95% confidence interval 1·14 to 12·57).. Being born small for gestational age may be a predictor of raised blood pressure in early adult life.. ...

Results Longer gestation from 23 to 45 weeks was associated with lower risk of poor literacy and numeracy. Adjusted relative risks for being at or below national minimum standard ranged from 1.12 (95% CI 1.03 to 1.22) for late preterm (32-36 weeks) for numeracy, to 1.84 (95% CI 1.48 to 2.30) for early preterm (23-31 weeks) for writing. Within term, every additional week of gestational age was associated with small decreased risks of poor literacy and numeracy (eg, relative risks for poor numeracy 1.10, 95% CI 1.01 to 1.20 for 37 weeks). Population-attributable fractions for poor achievement were highest among children born early term (37-39 weeks) due to their higher population prevalence. ...
