Q

how can protein energy supplementation during pregnancy affect fatal growth in woman with energy or protein deficit?

improve fatal growth
increase brith weight and height
decrease the percentage of low birth weight

however excess protein in woman with diet that already has adequate protein may conversely impair the fatal growth

Q

what was the dutch winter famine study?

A

Transgenerational effects of prenatal exposure to the Dutch famine on neonatal adiposity and health in later life

Children of the pregnant women were smaller, more susceptible to diabetes, obesity and cardiovascular disease and more likely to have smaller children themselves

Q

vitamin D deficiency during pregnancy?

A

Q

Why is folic acid recommended during pregnancy?

A

What: to reduce the risk of neural tube
defect (NTD)

Why: Folate acts as a cofactor for enzymes involved in DNA and RNA biosynthesis.

Who: all women planning a pregnancy and up to 12 weeks or more. Obese women and those with epilepsy require higher dose

Action: 400 micrograms for all, 5mg for women with raised BMI >30 or previous NTD

Q

what can breast feeding prevent in the mother?

A
Type 2 Diabetes
• Breast Cancer
• Ovarian Cancer
• Postnatal Depression
• Breastfeeding - still the most widespread form of birth spacing globally means - smaller family size - more children survive - enhanced maternal health

Q

what is colostrum?

A

days 1-3 breast milk

thicker and more concentrated than breast milk
Yellowish or clear
Small volume to allow baby to get rid of excess tissue fluid without overloading kidneys
Higher concentrations of antibodies, white blood cells and other anti-infective proteins than mature milk
Mild laxative effect
Rich in growth factors
Richer in Vitamins A and K than mature milk
Creates an acidic environment

Q

how is there IgA in breast milk?

A

Maternal mucosal surfaces encounter microbes in her own and baby’s environment

  • -> Maternal lymphocytes at mucosal surfaces stimulated by microbes to produce specific IgA
  • -> Maternal lymphocytes migrate to breast
  • ->Maternal lymphocytes produce specific IgA against microbes encountered which is then secreted into breastmilk
17
Q

what are lysosyme?

A

Bacteriocidal and anti-inflammatory action

contributes to the destruction of E Coli

18
Q

why do babies who are formula fed have increased risk of gastroenteritis?

A

free iron in the gut (which bacteria feed on)
no lactoferrin (mops up free iron)
no bifidus factor ( so pH conducive to bacterial growth)
no oligosaccharides (to inhibit attachment of pathogens)
no secretory IgA
no entero/broncho-mammary pathway (for antibody production )
no white cells (to destroy bacteria)
no lysozyme (to destroy bacteria)
no viral fragments (to stimulate antibody response and trigger babys own immune system)
no anti-inflammatory molecules (to moderate response to pathogens )
no stem checks

19
Q

what is the prolactin response?

A

baby sucks
sensory impulses pass from the nipple to the brain
prolactin secreted by anterior pituitary glad goes via blood stream to breasts
Lactocytes produce milk

20
Q

what is prolactin?

A
  • Directs the lactocytes to produce milk
  • Levels remain high for 90 minutes after a feed
  • More sucking makes more milk
  • Levels are higher at night
  • Makes mother feel more relaxed and sometimes sleepy
  • Suppresses the release of gonadotrophin, therefore inhibits ovulation
21
Q

what is the prolactin receptor theory

A

expulsion of placenta opens receptor sites
surges of prolactin prime the receptor sites

mothers can stimulate receptor sites by:
skin to skin contact
early feeds
explosion of breast milk

22
Q

what is oxytocin

A
  • Directs the myo-epithelial cells
  • Makes the milk flow
  • Helps the uterus to contract
  • Can start working before the baby suckles
  • Easily affected by the mother’s thoughts, feelings and sensations
  • Triggers calmness, mothering instinct and feelings of love
23
Q

what is the oxytocin reflex?

A

baby suckers
sensory impulses pass from the nipple to the brain
oxytocin secreted by posterior pituitary gland goes via blood stream to breast
mayo-epithelial cell contract and expel milk

helped by sight
becomes conditioned over time
hindered by anxiety, stress, pain and doubt

24
Q

what are the feedback inhibitors of lactation?

A

• Breast milk contains a protein (FIL) that causes the lactocytes to ignore the signals from prolactin when the breast is full.
• If only a little milk is removed or there is a long gap between feeds, milk production will slow down.
• More frequent sucking/feeds (the more milk baby removes) – the less effect the FIL will have.
Frequent, effective breastfeeding will help to ensure sufficient milk production
