3 Embryology and Development
BIOL 6505 − INTRODUCTION TO FETAL MEDICINE 3. EMBRYOLOGY AND DEVELOPMENT Arlet G. Kurkchubasche, M.D. INTRODUCTION Embryology – the field of study that pertains to the developing organism/human Basic embryology –usually taught in the chronologic sequence of events. These events are the basis for understanding the congenital anomalies that we encounter in the fetus, and help explain the relationships to other organ system concerns. Below is a synopsis of some of the critical steps in embryogenesis from the anatomic rather than molecular basis. These concepts will be more intuitive and evident in conjunction with diagrams and animated sequences. This text is a synopsis of material provided in Langman’s Medical Embryology, 9th ed. First week – ovulation to fertilization to implantation Fertilization restores 1) the diploid number of chromosomes, 2) determines the chromosomal sex and 3) initiates cleavage. Cleavage of the fertilized ovum results in mitotic divisions generating blastomeres that form a 16-cell morula. The dense morula develops a central cavity and now forms the blastocyst, which restructures into 2 components. The inner cell mass forms the embryoblast and outer cell mass the trophoblast. Consequences for fetal management: Variances in cleavage, i.e. splitting of the zygote at various stages/locations - leads to monozygotic twinning with various relationships of the fetal membranes. Cleavage at later weeks will lead to conjoined twinning. Second week: the week of twos – marked by bilaminar germ disc formation. Commences with blastocyst partially embedded in endometrial stroma Trophoblast forms – 1) cytotrophoblast – mitotic cells that coalesce to form 2) syncytiotrophoblast – erodes into maternal tissues, forms lacunae which are critical to development of the uteroplacental circulation. -
Breastfeeding Complications (Women) 2001.04
05/2015 602 Breastfeeding Complications or Potential Complications (Women) Definition/Cut-off Value A breastfeeding woman with any of the following complications or potential complications for breastfeeding: Complications (or Potential Complications) Severe breast engorgement Cracked, bleeding or severely sore nipples Recurrent plugged ducts Age ≥ 40 years Mastitis (fever or flu-like symptoms with localized Failure of milk to come in by 4 days postpartum breast tenderness) Tandem nursing (breastfeeding two siblings who are Flat or inverted nipples not twins) Participant Category and Priority Level Category Priority Pregnant Women 1 Breastfeeding Women 1 Justification Severe breast engorgement Severe breast engorgement is often caused by infrequent nursing and/or ineffective removal of milk. This severe breast congestion causes the nipple-areola area to become flattened and tense, making it difficult for the baby to latch-on correctly. The result can be sore, damaged nipples and poor milk transfer during feeding attempts. This ultimately results in diminished milk supply. When the infant is unable to latch-on or nurse effectively, alternative methods of milk expression are necessary, such as using an electric breast pump. Recurrent plugged ducts A clogged duct is a temporary back-up of milk that occurs when one or more of the lobes of the breast do not drain well. This usually results from incomplete emptying of milk. Counseling on feeding frequency or method or advising against wearing an overly tight bra or clothing can assist. Mastitis Mastitis is a breast infection that causes a flu-like illness accompanied by an inflamed, painful area of the breast - putting both the health of the mother and successful breastfeeding at risk. -

The Key to Increasing Breastfeeding Duration: Empowering the Healthcare Team
The Key to Increasing Breastfeeding Duration: Empowering the Healthcare Team By Kathryn A. Spiegel A Master’s Paper submitted to the faculty of the University of North Carolina at Chapel Hill In partial fulfillment of the requirements for the degree of Master of Public Health in the Public Health Leadership Program. Chapel Hill 2009 ___________________________ Advisor signature/printed name ________________________________ Second Reader Signature/printed name ________________________________ Date The Key to Increasing Breastfeeding Duration 2 Abstract Experts and scientists agree that human milk is the best nutrition for human babies, but are healthcare professionals (HCPs) seizing the opportunity to promote, protect, and support breastfeeding? Not only are HCPs influential to the breastfeeding dyad, they hold a responsibility to perform evidence-based interventions to lengthen the duration of breastfeeding due to the extensive health benefits for mother and baby. This paper examines current HCPs‘ education, practices, attitudes, and extraneous factors to surface any potential contributing factors that shed light on necessary actions. Recommendations to empower HCPs to provide consistent, evidence-based care for the breastfeeding dyad include: standardized curriculum in medical/nursing school, continued education for maternity and non-maternity settings, emphasis on skin-to-skin, enforcement of evidence-based policies, implementation of ‗Baby-Friendly USA‘ interventions, and development of peer support networks. Requisite resources such as lactation consultants as well as appropriate medication and breastfeeding clinical management references aid HCPs in providing best practices to increase breastfeeding duration.

“Morning Sickness”
“Morning sickness” “Morning sickness”, which often occurs throughout the day, is a condition characterized by nausea, indigestion, and periodic vomiting during the first trimester of pregnancy. The condition varies from mild stomach upset to severe vomiting requiring hospitalization. Despite many years of study, the cause of these symptoms is unknown. Many women worry that failure to eat a full array of foods will somehow harm the fetus, but there is no cause for concern. In the era when intravenous nourishment was impossible, women with severe vomiting were treated with fluids only. Their babies were healthy and of normal birth weight. “Morning sickness” typically passes as the first trimester ends. In the meantime, the following suggestions can help: Separate solid food from liquids. Do not drink and eat simultaneously. Eat small amounts of food throughout the day. Bland foods such as bread or crackers work well. Wear acupressure bands at the pericardium 6 position of each wrist. This site is located three fingerbreadths above the wrist. Get plenty of rest and avoid stress. Avoid spicy and fatty foods. Try small dose of vitamin B6 (10-50mg three times a day). Add half a Unisom Nighttime Sleep Reliever to the B6 to concoct Benedectin, one the safest drugs for morning sickness ever developed. While the actual drug is not available in the US, experts on medications in pregnancy condone its use. If prenatal vitamins make you sick, take folic acid only (in a dose of 800 ug/day) until you feel better. Try antacids such as TUMS EX (which also contains calcium). -
Module 2: Hypertensive Disorders of Pregnancy and Gestational Diabetes FINAL Description Text
Module 2: Hypertensive Disorders of Pregnancy and Gestational Diabetes FINAL Description Text Welcome to the module Hypertensive Disorders of Pregnancy and Gestational Diabetes. In this module, we will be discussing hypertensive Slide 1 disorders of pregnancy, including pregnancy induced hypertension and preeclampsia. We will also discuss Gestational Diabetes as well as nutrition solutions related to these issues Slide 2 We will begin by discussing hypertensive disorders in pregnancy. There are at least 5 distinct categories of hypertension and related disorders that occur during pregnancy. These categories are: preeclampsia/eclampsia, chronic hypertension, preeclampsia Slide 3 superimposed upon chronic hypertension, gestational hypertension and transient hypertension. Each of these will be discussed individually throughout the module, with recommendations based on best practices provided. Blood pressure is the force of blood on the walls of the arteries. Systolic blood pressure is measured when the ventricles are contracting while diastolic pressure is measured when the ventricles are relaxed. Normal Slide 4 blood pressure is typically 120/80 mm Hg.The general definition of high blood pressure in adults is a systolic BP > 140 mg HG or a diastolic blood pressure > 90 mm Hg. These criteria should be used for women throughout pregnancy. Chronic hypertension often exists prior to pregnancy and continues throughout pregnancy. It may not be noticed until the second trimester of pregnancy if prenatal care is delayed or if women have suffered from prolonged nausea and vomiting or morning sickness. If hypertension is Slide 5 diagnosed in early pregnancy and persists past 6 weeks postpartum, it would be considered to be a chronic health condition. -

The Stunted Development of in Vitro Fertilization in the United States, 1975-1992
EMBRYONIC POLICIES: THE STUNTED DEVELOPMENT OF IN VITRO FERTILIZATION IN THE UNITED STATES, 1975-1992 Erin N. McKenna A Thesis Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements for the degree of MASTER OF ARTS May 2006 Committee: Dr. Leigh Ann Wheeler, Advisor Dr. Walter Grunden ii Abstract The federal government’s failure to fund research on in vitro fertilization has had an important legacy and significant consequences in the United States. Due to the dismantling of the Ethics Advisory Board in 1980, no government funding was provided for research for in vitro fertilization (IVF), embryo transfer (ET), and gamete intra-fallopian transfer (GIFT). The lack of government funding, regulation, and involvement has resulted in the false advertising of higher success rates to lure patients into the infertility specialists’ offices. In their desperation to have children, consumers of such medical technologies paid exorbitant fees that often remained uncovered by insurance companies. The federal government enacted legislation in 1992 attempting to alleviate some of the aspects of exploitation of the consumer-patient. The government’s recognition of the importance of such procedures was hit and miss, though, much like the reproductive technology itself. The legacy is one that has resulted in American citizens who now turn to developing countries such as Israel and India, where the treatment is drastically cheaper and often more effective. I attempt to explain the federal government’s response to New Reproductive Technologies (NRTs), beginning with in vitro fertilization, thus exploring why and how this debate has inextricably been linked to the ongoing abortion debate. -
