The poorly perfused and hypoxic placenta is thought to synthesise and release increased amount of vasoactive factors including soluble fms-like tyrosine kinase-1 (sFlt-1), cytokines (interleukin-6 (IL-6), tumour necrosis factor (TNF-alpha), angiotensin II (ANG II) type 1 receptor antibodies (AT-AA) and thromboxane TX. Elevation in these factors are proposed to result in endothelial dysfunction by decreases in bioavailable Nitric Oxide (NO) and increased reactive oxygen species (ROS) and endothelien-1(ET-1), which in turn result in changed renal function, increased total peripheral resistance (TRP), and ultimately hypertension. PIGF is a placental growth factor and VEGF is a vascular endothelial growth factor. These are …show more content…

Moebius Syndrome Analysis

1103 Words | 5 Pages

Currently the most accepted hypothesis is a vascular disruption causing a hypoxic/ischemic insult to the brainstem in the first trimester23, 24. This can be caused by various teratogens evoking uterine contractions. The following teratogens have been described including: gestational hyperthermia 25, 26, chorionic villus sampling 27, abuse of benzodiazepines 28, alcohol 25,cocaine29, thalidomide 30, ergotamine 31 or self-induced abortion – misoprostol 32. Hypoplasia or aplasia of the nuclei can also be caused by genetic mechanisms 1, but because the majority of Moebius syndrome cases are sporadic, genetics play only a minor role. So far three different chromosomal regions for familial Moebius syndrome have been reported: MBS1 (OMIM 157900, 13q12.2-q13) 33, 34, MBS2 (OMIM 601471, 3q21-q22) and MBS3 (OMIM 604185, 10q21.3-q22.1) 35, 36.

A Summary Of Postpartum Depression

Out of the 3,039 women initially screened, 1,423 women were used for this sample study, the others being excluded due to lack of assessment or data on the questionnaire. All of these women were receiving prenatal care at the University Obstetrics Clinic and delivered at the University of Washington Hospital during the time period of January 2004 to June 2011. After all of the exclusions made, I believe the sample size that was used was large enough to obtain information from the screenings. Data was also collected during a 7 year time period, which I believe is an adequate amount of time to obtain a varied amount of information on predictor variables.
