gonadotropin-releasing hormone
released from hypothalamus to stimulate FSH and LH
Anterior Pituirary Hormones
FSH and LH
Ovarian Hormones
estrogen and progesterone
FSH and LH in Ovary

Uterine Cycle
menstural phase
proliferate phase
secretory phase
ischemic phase
Menstural Phase
Uterine Cycle
3-6 days, starts on first day of flow
uterus sheds
progesterone and estrogen are low
Proliferate Phase
Uterine Cycle
end of menses to ovulation (day 14)
influenced by outside factors and hypothalamus changes: stress, diet, sleep
high in estrogen, stimulating endometrium to fill with blood
increase in cervical mucus, thin and less acidic
Secretory Phase
Uterine Cycle
after ovulation
progesterone increases, endometrium swells to prepare for a fertilized ovum, estrogen decreases
if fertilization does not occur, estrogen and progesterone decrease, vasoconstriction
Ischemic Phase
Uterine Cycle
blood supply to the endothelium sloughs and blood escapes with tissues and mucus
does not happen if fertilization occurs
estrogen and progesterone decrease
Ovarian Phase
follicular phase
luteal phase
Follicular Phase
Ovarian Cycle
with menstrual and proliferate phase
developing viable follicles for ovulation
estrogen is secreted by follicles and surges to the end of this phase - leads to positive feedback on LH leading to luteal phase
Luteal Phase
Ovarian Cycle
with secretory an ischemic phase
ovum released from follicle - follicle turns into corpus luteum
LH and FSH decrease, progesterone and estrogen increase to prepare uterine lining

Buprenorphine: Heroin Treatment
- better treatment adherence with fewer side effects and overdoses in comparison to methadone
Naltrexone: Heroin Treatment
- opioid antagonist, non-addictive, may improve compliance if an issue
- work through same opioid receptior, but safer
Patho of Diabetes
diabetes: metabolic disease with hyperglycemia from insulin secretion defects
* makes blood more viscous and causes high BV, cellular dehydration, polyuria, and polydipsia (excessive thirst)
* starts to burn both proteins and fats = ketones and fatty acids which causes weight loss because of breakdown in tissue
* change in vascular circulation with organs
Four Cardinal S/S of Diabetes
- Polyuria
- Polydypsia
- Weight Loss
- Polyphagia
Polyuria in Diabetes
excrete large volumes of urine
* glucose hyperconcentrated = kidney loses ability to pull glucose from water
* osmotic pressure rises, H2O cannot be absorbed back into blood = urination
Polydipsia in Diabetes
dehydration in cells, can be from polyuria
Weight Loss in Diabetes
breakdown of fats and muscles to make ketones and fatty acids
Polyphagia in Diabetes
tissue breakdown = starvation
person may eat excessive amounts of food
Classifications of Diabetes Mellitus
- Type 1 DM: absolute insulin deficiency
- Type 2DM: insulin resistance
- Gestational Diabetes: any degree of glucose intolerance
White’s Classification of Diabetes
in pregnancy
based on age of diabetes, duration of illness, presence of any organ involved
* eyes and kidneys
* classes A-C: positive pregnancy outcome if glucose controlled
* classes D-T: poor outcome, vascular damage
Influence of Pregnancy of Diabetes on Physiological Changes in 1st Tri.
alter insulin requirements
* insulin decreases because increased estrogen and progesterone stimulates pancreas to make more insulin
* this increases peripheral use of glucose
* hypoglycemia with N/V
Influence of Pregnancy of Diabetes on Physiological Changes in 2nd and 3rd Tri.
maternal metabolism directed toward supplying adequate nutrition for fetus
* placental hormones: cause insulin resistance
* promote more blood glucose to transfer through placenta
* fetus produces nore glucose when it gets glucose
Influence of Pregnancy of Diabetes on Hormones
- hPL
- somatotropin (growth hormone)
- promotes more insulin on bloodstream
- do not produce sufficient amount of insulin to maintain glucose homeostasis
Other Influences of Pregnancy in Diabetes
- accelerates progress of vascular disease
- more difficult to control in pregnancy
- fetus will get bigger since insulin turns into fat
Maternal Risks with Diabetes
- poor glycemic control = miscarriage and big baby (over 4000g)
- risk for C-section
- hydramnios: fetal urination, uterine dysfunction, infection
- hyperglycemia and ketoacidosis
- high risk for infections
- worsening retinopathy
Fetal Neonatal Risks with Diabetes
produce insulin around 14 wks = growth hormone
* macrosomia: could have birth injury delivering vaginally
* congenital abnormalities
* IUGR: interuterine growth retardation = decreased profusion to placenta with decreased vascularity
* respiratory distress syndrome: inhibit enzymes necessary for surfactant production
Clinical Therapy for Diabetes
- early detection and diagnosis
- assess risk at 1st visit
- if low risk: screen at 24-28wks
- if high: screen asap

no protein (-)
Rh - Mother
Rh + baby
antibody-antigen response
sensitized mother
No Treatment to Sensitized Mother
- jaundice
- anemia
- brain damage
- heart failure
- death
Maternal Alloimmunization
when woman’s immunse system is sensitized to foreighn erythrocyte surface antigen
stimulates the production of IgG antibodies
Sensitized Woman
small amounts of fetal blood cross the placenta
maternal IgM antibodies are produced and RhoGam will not help since she is sensitized
2nd Pregnancy and Sensitized Woman
Rh+ child - IgG antibodies produced and cross placenta
risk for hemolysis of fetal RBC
Indirect Coomb’s Test
identifies antigen that could cause problems in newborns or mother
possible need for transfusion
positive test = antibodies present, no RhoGam
negative test = no antibodies present

- 3 min: 70-75%
- 4 min: 75-80%
- 5 min: 80-85%
- 10 min: 85-90%
Thermoregulation
balance of heat loss and heat protection
* hypothermia: common because of decrease subcutaneous fat, blood vessels close to surface of skin
4 Types of Heat Loss Mechanisms
- evaporation
- convection
- conduction
- radiation
Convection
air flowing by skin and carrying away body heat with it
* air currents
Radiation
transfer of heat between 2 objects that are not in contact with each other
* indirect source, cool window warm baby
Evaporation
moisture on body lost to the environment
* H2O/vapor, baby born wet and needs to be dried
Conduction
loss of hear from body surface to cool surface and in contact
* cold scale and warm baby
Neutral Thermal Environment
maintenance of thermal balance
* babies maintain this through non-shivering thermogenesis by using the metabolism of brown fat instead of shivering
Temperature Regulation
increased muscle activity, acrocyanosis, increased cellular metabilic activity, increased O2
* can create respiratory distress because temperature is dropping and less adipose tissue
* large body surface in relation to mass
Transition of Respiratory System into Extrauterine Life
- 6-12 hours after birth
- exchange of O2 and CO2
- maintenance of acid/base balance
- in utero: received O2 via placenta thru cord and 10% of CO is profusing
3 Needs of Respiratory System Once Born
- air replacing fluid
- onset of breathing
- increasesd pulmonary blood flow
Inflation of Breathing Mechanisms
- systemic vascular resistance increases
- pulmonary vascular resistance decreases
- all increases profusion of lungs
Air Replaces Fluid: Absorption
rest of fluid absorbed by blood vessels in lymphatics
Initial Inflation of Lungs
mechanical stimulation in utero: breathing amniotic fluid to promote growth and differentiation of lungs
* first breath: decrease in secretion into pulmonary fluid and reabsorb
Surfactant and Alveolar Stability
surfactant needed
* 6th-7th month: cells develop lecithin so thin walls of alveoli do not collapse after each breath
* surface tension pulls on film of fluid in alveoli and lecithin is a surface acting agent that reduces surface tension of fluid by reducing muscular effor needed to draw air into lungs
* increases compliance
The First Breath
hardest thing for neonate to do
* requires pressure 10-15x that of later breaths
* inflating all alveoli
* 40% of air remains as residual because of surfactant
4 Initiations of Breathing
occur in respitory center in medulla
1. mechanical
2. sensory
3. thermal
4. chemical
Mechanical Initiation of Breathing
compression of fetal chest as it moves through birth canal
* chest recoild and creates negative intrathoracic pressure
* passive inspiration of air = replacement of fluid with air
Sensory Initiation of Breathing
tactile, visual, auditory
Thermal Initiation of Breathing
change in temperature signals respiratory system
Chemical Initiation of Breathing
- mild hypercapnia: increasing CO2 levels
- hypoxia: low O2 levels
- acidosis: low pH
- all stimulate respiratory system via peripheral chemoreceptors
- prostaglandins suppress respirations and drop with clamping cord
Increase in Pulmonary Blood
blood flow increases to lungs
* 10% of cardiac output perfuses pulmonary vasculature with replacement of fluid by air in lungs
* pressure shift: increased vascular resistance now decreases and leads to increased perfusion
* gas exchange can now occur at the level of capilaries
Characteristics of Newborn Respiration
- normal rate: 30-60 breaths/min
- shallow and diaphragmatic with brief pauses (5-15sec)
- apnea: over 20sec and may have skin or HR changes
- nose breathers since reflex to open mouth not there
- use of intercostal muscles, grunting, flaring indicates distress
Neonatal Circulatory System
1 cord vein: O2 and blood
2 cord arteries: deox blood
* systemic vascular resistance increases, pulmonary artery pressure decreases and when cord is clamped: placental circulation lost
* closure of fetal shunts: foramen ovale, ductus arteriosus, ductus venosus
Characteristics of Cardiac Function
right ventricle stronger in cardiac workload (2/3 of work)
* 4pt BP pressure different in arms and legs
APGAR Scores
assessed at 1 and 5 minutes, indicates extrauterine transition
* 7-10 = minimal no difference
* 4-6 = moderate difference
* 0-3 severe distress
APGAR: 0 Points

Phase 2 Transition Phase
sleep period: 1-4 hrs
* deep sleep to stabilize HR and RR

Difficult Transitions: Neonatal Difficulties
- lack of respiratory effors: neurologically depressed, impaired muscle function
- mucus blockages
- respiratory distress from impaired cardiac/lung functioning
Blood Volume of Newborn
80-90mL/kg of body weight
* dependent on cord clamping, could be 100
Delaying Cord Clamping
enhances pulmonary profusion
* increases iron stores
* risk of jaundice due to high number of RBC and organ damage from the viscosity of blood
Erythropoietin Saturation in Fetus
increases due to 50% saturation of fetal blood
* decreases production after birth
* resumes response to low hemoglobin = jaundice
* RBC lifespan 33% less than adult
* leukocytosis = normal and increase in WBC
Gastrointestinal Adaptations
- stomach: size of marble
- 36-38 wks: adequate intestinal and pancreatic enzymes
- proteins require more digestion but absorn and digest fats less efficiently
Colostrum and the Stomach
correlate with the maturity of enzymes - amylase and lipase lacking of ar birth
* decreased fat, increased antibody and protein in colostrum
Swallowing
experience it in utero
* gastric emptying in utero: swallow vernix
Air and the Stomach
enters immediately after birth
* hits small intestine 2-12 hrs
* hear bowel sounds hr after birth
* meconium 8-24 hrs
Weight Loss
1st 3-4 days
* colostrum acts as a laxative
* 3.5% formula fed
* 7% breastfed
* regained by day 10
Urinary Adaptations
- at risk for fluid shifts because kidneys are immature
- glomerular filtration rate low
- limited capacity to concentate urine
- void in the 1st 24 hrs - uric acid crystals
Water and Newborns
cannot reabsorb water to maintain vital organ functioning
* risk for over and dehydration
Hepatic Adaptations
liver takes up 40% of abdominal cavity
iron storage, bilirubin conjucation, coagulation of blood
Iron Storage: Hepatic Adaptations
mom’s iron intake lasts for 5-6 months
Glucose: Hepatic Adaptations
diffuses across the placenta, not insulin, fetus makes own
* cuts off at birth, rapidly utilize from stress of delivery
* goes to glycogen if depleted - liver needs to be able to do this
* no greater than 40 mg/dL
Jaundice
normal biological response
refers ot the increased yellow pigment in tissues from high levels of bilirubin
Bilirubin
product of fetal RBC destruction
* heme: iron
* globin: protein
Unconjucated Bilirubin
indirect bilirubin from the heme
* fat soluble and unable to be excreted
* crosses the placenta
Conjucated Bilirubin
direct bilirubin
Total Bilirubin
total of unconjugated and conjugated
* 2-3 mL/dL then 5-6mL/dL in 3-5 days
RBC in Newborn
hemolysis occurs as lungs oxygenate newborn
Hyperbilirubinemia: A Breakdown
- bili enzymatically converted in liver, water soluble bili excreted in the urine
- glucantranferase: responsible for urine/stool color
- enzyme is lacking since liver immature, this impairs liver’s ability to conjugate bili and excrete it
- creates excessive amounts of bili in the blood, risk to cross the blood-brain barrier
Normal Intestinal Flora and Bili
reduces conjugated bili to urobilinogen
* excreted in the kidneys and stercobilinogen and excreted in the feces
* requires adequate calories and hydration
* delay in feeds causes reabsorption
Transcutaneous Bilirubin
- done prior to discharge
- non-invasive measurement using light to measure bili in blood
- if suspicious: draw blood
Bilirubin Levels
high-risk
high-intermediate
low-intermediate
low-risk
Why Newborns are Prone to Bili
- accerated destruction of RBC
- blood type or Rh incompatibility
- bruising from instruments, cephalohematoma
- decreased hepatic function
- decreased albumin levels
- drugs that interfere with conjugated bili: indomethacin, sulfa drugs, salicylates
- maternal enzymes in breastmilk inhibit conjugation
BF and Jaundice
- early onset, decreased intake of BM
- BF infants have more bili
- peaks 2-4 days
- associated with poor feeding
Meconium and Jaundice
leads to dehydration and delay in passing this
* mec has conjugated bili and if not passed in a timely manner, reabsorbs and transported to liver
* enterohepatic circulation
BM and Jaundice
- related to milk composition, rare
- late onset = 2-3 wks
- newborns are healthy
- treatment: monitor serum bili levels
- may stop BF for 12-24 hrs and if bili levels drop = BMJ
- genetic component
Passive Immunologic Adaptations: IgG
IgG crosses placenta
* 3rd trimester
* begin immunizations at 2 months because of low levels of antibodies and immature WBC
* more vulnerable infections
* Hep B: given at birth
Passive Immunologic Adaptations: IgA
in colostrum
* protects against GI and respiratory infections
Neurologic Functioning
- lots of neuro development in postpartum period
- time of high risk to intellectual development
- brain: one quarter size of adult brain
- myelination of nerve fibers incomplete
Nutrition Across Lifespan
- need lots of nutrients
- most vulnerable to poor nutrition during periods of rapid growth - unborn and 1st yr of life
Healthy People 2020
BF = unequalled way of providing ideal food for healthy growth and devlopment of infants
* 81.9% of mom’s initiate BF in early postpartum period
* 25.5% exclusively BF at 6 months
* 34% continue at 1 year
* 25.4% of BF infants receive formula before 2 day and want to go down to 14.2%
* 2.9% birth in places with recommended BF care and want to go down to 8.1%
Breastfeeding and Other Foods
- 1 mil infants die because given food too early and not breast fed
- rooming in with unrestricted BF
- no food or drink than BM unless medically necessary
Contraindications to BF
- HIV
- Active Untreated TB
- Human T-cell leukemia virus type 1
- exposure to toxic chemicals
- use of illegal drugs
- children with metabolic disorders / allergies (galactosemia)
