Filter by:: The aim of this study is to investigate Cord blood irisin and nesfatin-1 levels in pregnancies with intrauterine growth retardation and to determine whether they are associated with abnormal fetal doppler findings or not.
Tahneek is an Arabic word which means putting something sweet such as dates, in the infant's mouth after the birth. Neonatal hypoglycemia is common in the first few days after birth. Up to 15 % of normal newborn babies will have low blood glucose concentrations. It has been demonstrated that treatment of neonatal hypoglycemia with oral dextrose gel was more effective than feeding alone in reversing the hypoglycemia, and also reduced the rate of NICU admission. investigators study is using dates to asses its effect on hypoglycemia in infants at risk.
TREATMENT OF INTRAUTERINE GROWTH RESTRICTION WITH LOW MOLECULAR WEIGHT HEPARIN.
High risk women for growth restricted fetuses will randomized in the second trimester into different strategies applied to the mothers: a stress reduction program based on mindfulness techniques or a nutrition interventional program based on Mediterranean diet.
When indicated, a conservative management plan of IUGR was undertaken. Doppler studies were performed within the last week before delivery The results of Umbilical artery (UA) Doppler velocimetry were categorized as normal , increased , absent, and reversed . Patients were admitted for close surveillance in the case of worsening of maternal or fetal conditions (e.g. absent or reversed UA blood flow, and severe preeclampsia). Tissue samples The general shapes of placentas were assessed. The collected placentas were weighed by trimming the membranes and umbilical cord. Then the diameters and thickness of placentas were noted. The position of insertion of umbilical cord on the fetal surface of placenta was observed. Transverse cuts were made through the maternal surface at a distance of 1-2 cm in bread loaf manner and examined for the pale areas. All placentas were immersed in 10% formalin overnight and examined on the next day. For each placenta, blocks containing cord, membrane and full thickness of villous tissue were prepared. Whole thickness villous tissue blocks were obtained from three zones, i)central zone ii) peripheral zone and iii) intermediate zone between the first two zones, so as to include all areas of placenta. Placental bed biopsies were obtained at Caesarean sections with direct visualization of the placental site. Biopsies of at least 1cm were taken. The specimens were fixed in buffered formalin. The tissues were processed and stained with Haematoxlyin and Eosin. Microscopic study of placenta was carried out utilizing a set of standard criteria for villous and intervillous lesions Immunohistochemistry Expression of VEGF and CD34 was analyzed in 75 (50 placenta of IUGR and 25 of control) placental villous tissues. Immunostaining was performed by the streptavidin-biotin-peroxidase method. Evaluation of immunohistochemical staining To determine the MVD, the stained placental vasculature. Tissue sections were initially screened microscopically at low power (100×) to identify the areas of highest vascularization ("hot spots"). Evaluation of immunohistochemical staining of VEGF:
Preeclampsia (PE) and intrauterine growth restriction (IUGR) are clinical manifestations of placental insufficiency. These complications affect 5-15% of pregnancies, and are responsible for up to 20% of preterm births. Women who develop PE during pregnancy also have an increased risk for cardiovascular events, both at short and long term. This justifies the need to improve diagnostic tools to identify patients at risk for these complications. PE and IUGR are multifactorial entities. Screening algorithms should thus include several parameters to achieve high detection rates. Research has mainly focused in the analysis of biophysical and biochemical parameters, and the study of the placenta itself has not been included in current diagnostic strategies. Investigators hypothesize that detection rates of preeclampsia and intrauterine growth restriction could be improved by the study of placental characteristics in the first trimester of pregnancy.
Intrauterine growth restriction is a common and complex obstetric problem. Intrauterine growth restriction is noted to affect approximately 10-15 % of pregnant women. Intrauterine growth restriction is diagnosed antenatal; however, some of these fetuses, especially if unscreened during pregnancy, may be detected only in the neonatal period. It is very important for obstetricians and perinatologists to identify growth restricted fetuses, because this fetal condition is associated with significant perinatal morbidity and mortality. Omega 3 is composed of polyunsaturated fatty acids with a double bond at the third carbon atom from the end of the carbon chain. The fatty acids have two ends, the carboxylic acid end, which is considered the beginning of the chain, thus "alpha", and the methyl end, which is considered the "tail" of the chain, thus "omega." Omega3 improve fetal wellbeing by two mechanisms: Firstly, maternal and docosahexaenoic acid supplementation during pregnancy and lactation normalizes intrauterine growth restriction induced changes in adipose deposition and visceral PPARĪ³ expression. Secondly, maternal docosahexaenoic acid supplementation increases serum adiponectin, as well as adipose expression of adiponectin and adiponectin receptors. Novel findings suggest that maternal docosahexaenoic acid supplementation normalize adipose dysfunction and promote adiponectin-induced improvements in metabolic function in intrauterine growth restriction
Placental insufficiency is responsible for fetal loss in about 40% of all stillbirths and long term neurological deficits. The mean interval from diagnosis of brain sparing of severe IUGR fetuses to delivery has been recently identified by only seven days (Flood K et al, Am J Obstetrics and Gynecology 2014). The critical placental player in the active amino acids (AA) transport from the mother to the fetus is the trophoblast, which is irreversibly changed in severe IUGR fetuses caused by placental insufficiency. Thus, a logical partial solution of IUGR could be the direct supply of AAs and glucose to the fetus, in order to improve the fetal growth, normalize the fetal programming and to prolong the pregnancy. The aim of this prospective pilot study is to further test the efficacy of the administration of AAs and glucose supplementation with hyperbaric oxygenation (HBO), via a subcutaneously implanted intraumbilical perinatal port system, as a treatment option for severe IUGR human fetuses with brain sparing.
This will be a quasi-experimental study comparing blood glucose values 30 minutes after feeding alone or feeding + 40% dextrose gel in newborns at risk for transient neonatal hypoglycemia.
The purpose of this study is to evaluate the use of functional MRI in pregnant women as a non-invasive diagnostic tool to detect placental insufficiency and differentiate healthy fetuses from the intra-uterine growth restricted ones. Functional MRI in pregnant women can detect a variation of the MRI signal (called BOLD effect) from the placenta and the fetus when the mother is breathing pure oxygen. This study aims hence to demonstrate the difference in the BOLD effect between normal feto-placental units and growth restricted ones.
