Q

Why edentate patients have lower nutrition status

A
  • Dentures decrease chewing function (objective and perceived), decreased biting force, social aspect, lose the enjoyment of eating
  • Low in fibre due to avoiding hard fruit, veg, nuts
  • Lower plasma concentration of vitamin C
  • More saturated fat as it is softer to eat
  • Avoid foods with pips and seeds because cause gum irritation if gets beneath the denture
  • Low protein, energy, BMI

Q

What is anthropometry and kinanthropometry. How it can be used

A
  • scientific procedures and processes of acquiring anatomical dimensional measurements such as lengths, breadths, girths and skin folds with specialist equipment.
  • Kinanthrometry = using anthropometric measures in relation to other scientific parameters such as human movement, physiology or applied health sciences

-Helps us compare info against a reference, provides an indication of risk

Q

Pros and cons of BMI

A

-Pros: easy, non-invasive, more informative than weight or height alone (kg/m2), Permits meaningful comparisons of weight status within and between populations.
Makes it possible to identify individuals and groups at increased risk of morbidity and mortality, Enables priorities to be identified for intervention at individual and community levels, Provides a firm basis for the evaluation of interventions

-Cons: excess weight not always excess fat, does not consider fat distribution (visceral/ subcutaneous), body composition,

Q

Reasons why are babies may be breastfed after 12 months

A
  • delays maternal mensus
  • for babies, it reduces diarrhoea, respiratory infection, shigellosis (from contaminated faeces/ food/ water)
  • helps hydration when lack of clean water
  • good nutrition if lack of adequate complementary food

Q

What are the benefit of nocturnal breastfeeding

A
  • Prolactin levels in nocturnal feeds are higher which keeps the milk supply steady for longer
  • Contraceptive effect: Nocturnal breastfeeding extends the lactational amenorrhea
  • Nocturnal feeding is associated with a lower risk of Sudden Infant Death Syndrome
  • in very early life stomach volume is small and so frequent feeding helps achieve an adequate milk intake
  • Important for babies with faltering weight as can contribute 20% of intake
  • Serotonin in breast milk helps baby sleep and mothers who nurse nocturnally get more sleep
17
Q

Benefits of on-demand infant feeding

A
  • Recommended by WHO
  • increases milk flow so helps nutritional adequacy
  • reduced hunger upsets
  • can help regulate baby’s body temperature and blood glucose
  • boosts oxytocin = happier
18
Q

Explain the different types of formula milk that are used instead of breast milk.
- hypoallergenic infant formula, low or lactose free, nutrient enriched post discharge formula, soya formula, follow on formula

A
  • infant formula: does not protect babies against infection, but are based on breast milk composition and safety factors. Contain whey and casein
  • hypoallergenic infant formula: for those lactose intolerant/ allergic. Fully hydrolysed cow’s milk proteins. Bizarre taste so sugars often added
  • low or lactose free: no lactose or casein. Glucose and sucrose
  • nutrient enriched post discharge formula: for babies born early
  • soya formula: vegan. Soya protein and veg fat. Glucose and sucrose. Not recommend due to phytoestrogens
  • follow on formula: >6 months. More protein and micronutrients. Higher sugar. Unnecessary. No advantage over infant formula
19
Q

At what age is cows milk allowed and why What age when it can be the main source of milk

A

> 6months as babies unable to digest proteins in cow milk. Risk of allergy. Too high in protein

  • Not as main source of milk before 12 months
  • Semi-skimmed from 2 years if overweight
  • Skimmed milk – not before age 5 years as children need more calories from fat than older children do.
20
Q

Why parents might add sugar to infant feeds

A

[increases caries risk. especially when given at night]

  • To treat constipation: although there are better ways of doing this such as increasing fluid intake by boiling and cooling water (<6 months), or give prunes, pear, peach, plums, apricots or peas (>6 months) to soften stools
  • To aid digestion: no theory or evidence to support
  • To help the baby sleep and or reduce pain (e.g. from colic or gas): Sugar water can relieve pain, however, human breastmilk also provides pain relief, so there is no added benefit of adding sugar
21
Q

Complementary feeding. Things to promote and things to avoid

A
  • low in free sugars including (fruit juices or concentrates)
  • Unsweetened cereals, fruits and vegetables, and unsweetened yoghurts should be encouraged
  • Milk and water should constitute the majority of drinks.
  • From six months infants should be introduced to drinking from a cup and from one year drinking from a bottle should be discouraged
  • Tap water boiled and then cooled is safe for infants. Weak immune systems so important there are no microbes
  • Bottled mineral water may vary in composition and may be too high in some minerals and trace elements
  • Fruit juices and herbal drinks unnecessary from a nutritional standpoint
  • Drinks containing sugar substitutes are not recommended for infants and children under 3 years as they contain artificial sweeteners
  • small frequent portions. Low fibre. High fat (50% for under 5s, 35% for over)
  • sugar free supplements advised
22
Q

What are periodontal diseases and give examples. Risk factors

A
  • Spectrum of conditions affecting periodontal tissues
  • Plaque induced gingivitis and periodontitis (most common). Necrotizing periodontal diseases. Drug induced diseases. Periodontal abscesses

Oral hygiene, medication, smoking, microbial, stress, nutrition, genetics, diabetes, obesity [Nutrition has direct link and indirect, as it can also increase diabetes, plaque, obesity for example.]

23
Q

Effect of carbohydrates on periodontium

A
  • Indirect: A high sucrose intake is associated with increased plaque volume due to the production of extracellular glucans, so increased plaque volume causes gingivitis
  • Direct: no brushing for 4 weeks and low refined carbs diet caused increased dental plaque, but decreased gingival bleeding, so play a role in driving gingival inflammation
24
Q

Effects of malnutrition on the periodontium

A
  • Impairs innate and adaptive immune responses so reduced ability to respond to dental plaque. Associated with rapidly progressing and more severe forms of the disease
  • Causes cellular depletion of antioxidant nutrients, promoting immunosuppression
  • Can impair saliva host defence
  • Malnutirion associated with overgrowth of periodontal pathogens and yeasts
25
What 2 nutrients are important for maintaining the high cell turnover of gingival tissue.
- Protein (severe deficiencies can lead to Kwashiorkor disease which is associated with tooth loss and lesions - Folic acid
26
What is cancrum Boris/ noma. Risk factors
-Necrotising gingivitis can progress into this Severe gangrenous disease that causes a rapid necrotising destruction of soft and hard tissue of the face, including bone. -Risk factors: Malnutrition, smoking, stress, Poor oral hygiene Compromised immune system – infection with measles, malaria or HIV
27
What micronutrients are important for reducing risk of periodontal diseases. Functions
- Calcium (prevent bone and cementum resorption so prevent tooth loss) - vitamin D ( for cell development, neuromuscular functioning, antimicrobial, bone development and inflammation control) - folic acid (important for high cell turnover, reduces inflammation. In oranges) - vitamin B12 (healing properties, reduce tooth loss and inflammation)
28
How sunlight provides vitamin D. Food sources of vitamin D
- Major source of Vitamin D is the conversion of 7-dehydrocholesterol to Vitamin D3 via exposure of skin to UVB radiation - oily fish, egg yolks, butter, beef, cheese, mushroom, fortified margarine, cereal, milk, yoghurts
29
Function of vitamin C. What deficiency causes
- Powerful antioxidant associated with maintaining cell health - Immune function - phagocytosis and wound healing -Severe Vitamin C deficiency causes scurvy, ssociated with Swollen bleeding gums & tooth loss Affects supporting structures as impairs collagen synthesis, periodontal ligament, bone matrix, blood vessel walls
30
What 3 vitamin deficiencies cause tissue damage and impaired immune responses, increasing risk of gingivitis
calcium, folate, vitamin C and antioxidants
31
What is oxidative stress. What are antioxidants. Sources
- the imbalance between damaging reactive oxygen species, and protective antioxidant compounds - stress increases risk of chronic inflammatory diseases - causes damaged cells (neutrophils), tissue damage (bone, epithelium, periodontal ligament, gingiva), damaged lipids, proteins, DNA - Antioxidants slow the oxidation of other molecules, resisting free radicals. Dampen down inflammatory responses - Sources: green leafy veg, nuts, seeds, oily fish, meat. - Reactive oxygen species produced in periodontitis. Increase cytokines
32
What micronutrients are antioxidants
Vit A,C,E, iron, copper, selenium
33
What mediators are related to obesity and periodontitis
-TNF-α, IL-6 and leptin, which are involved in the pathophysiology of both diseases [-Increased expression of pro-inflammatory adipokines and diminished expression of anti- inflammatory adipokines]
34
What FA are found in vegetable. And in oily fish. Are they good or bad
- Vegetable oil = omega 6 = bad = increased periodontal disease progression - Oily fish = omega 3 = good =PUFA
35
Role of Omega 3 and 6 in COX pathway
- Arachedonic acid (omega 6) is used to produce inflammatory eicosanoids (PGE2) - Omega 3 inhibits this COX pathway to dampen down inflammation and prevent inflammatory diseases
