How does Cystic Fibrosis alter nutrient needs?
– Increased nutrient needs 2/2 increased WOB – Decreased food consumption 2/2 current illnesses – Reduced nutrient absorption 2/2 pancreatic insufficiency – Secondary illnesses, such as CF related diabetes, liver disease, and osteoporosis
26
What is the max dosing for PERT?
* <2500 units lipase/kg/meal * Do not exceed 10,000 units lipase/kg/day * Going above increases risk of fibrosing colonopathy
27
# **STUDY** Supplementation of salt for infants with CF
0-6 mos: 1/8 tsp per day >6 mos: 1⁄4 tsp per day
28
Can you use standard equations for energy needs in critical illness?
**NO!** * Standard equations are inaccurate in this population (risk of overfeeding) * The inflammatory response effects energy needs (effect on LBM)
29
# **STUDY** What is the best approach to calculating energy needs in critical illness
**Indirect calorimetry** ideal for malnutr or altering metabolic state If can't measure needs, use: **Schofield or WHO equations w/o stress factors**
30
Estimated needs for children with Burns
* Catabolic state lasting weeks post injury * Gold standard is to use indirect calorimetry * General goal is 120-130% of REE ## Footnote Children with burns >20% BSA will likely not meet EEN via PO intakes alone and will require some form of nutrition support
31
Estimated needs for obesity
* Per ASPEN Guidelines use indirect calorimetry instead of predictive equations * If no IC, use BMR * Look for laboratory abnormalities (ex: lipid panel, glucose) ## Footnote Note BMR can still provide excessive kcal
32
Children with lower energy needs
* Avoid overfeeding * BMR or condition specific equations * Assure protein and vitamin/mineral needs are met in setting of decreased kcal provision
33
Examples of children with lower energy needs
Traumatic brain injury, cerebral palsy, Trisomy 21, etc.
34
Protein Needs
* Dependent on age (decreases the older a child gets) * Higher needs during stressed states or loss (e.g., SBS, critical illness) up to 1.5 g/kg * Excessive protein intake (4-6 g/kg/day) can contribute to metabolic acidosis and azotemia
35
Fluid Needs
Holliday-Seegar
36
Note about fluid needs in infants <6 months
Avoid giving free water due to inadequate nutrient intake and possible electrolyte disturbances. ## Footnote Lytes disturbances 2/2 kidneys not proficient early in life with concentrating urine
37
Risks associated with not breastfeeding
* Decreased resistance to infection * Decreased gastrointestinal maturity * Increased risk of overfeeding * Increased risk of necrotizing enterocolitis in preemies * Increased risk of allergy development into childhood
38
# **STUDY** If an infant has galactosemia, what formula should they NOT receive?
Lactose-containing formulas ## Footnote Typically placed onto a soy formula
39
# **STUDY** What do cow milk and soy formulas have in common?
Increased risk of soy allergy/intolerance if infant also is milk intolerant/allergic ## Footnote Presenter would place on hydrolysate for infants with galactosemia
40
# **STUDY** What is the difference in kcal (NICU, post d/c, standard)?
* NICU/preemie: 24 kcal/oz * Post-Discharge (from NICU): 22 kcal/oz stay on this until 9 mo. corrected age * Both of these formulas are more calorically dense, higher in protein, higher in nutrients vs standard formula * Standard formula = 20 kcal/oz to mimic breast milk
41
# **STUDY** Vitamin K
Prophylactic supplementation in all newborns
42
# **STUDY** Vitamin D
* Exclusively breast fed – provide 400 IU/day once d/c home * Breast fed and formula fed – assess and supplement accordingly * Formula fed – no supplementation if daily volume of formula consumed is adequate
43
# **STUDY** Risk factors for Vit D deficiency
– Breast-feeding w/o supplementation – Dark pigmented skin – Birth prior to 32 weeks gestation – Location – Recent immigration from a developing country – At risk populations * Malabsorptive conditions * Epilepsy/Cerebral Palsy ## Footnote Epilepsy/CP - on antiseizure meds which can impact Vit D metabolism Birth prior 32 weeks - bone min density accumulation occurs in 3rd trim Develop country - malnutrition and/or nutrient def
44
# **STUDY** Vitamin B12
– Concern for breast fed infant if mother is vegan – Possible concern in intestinal failure infants/children depending on portion of SB resected
45
# **STUDY** Iron
* **Fortify in breast fed infants by 4-6 months** - this is when endogenous supply become depleted * Formula contains iron * May need to supplement in instances of malabsorption
46
# **STUDY** Fluoride
* No need to supplement from birth to 6 mo * **After 6 mo may need to supplement based on water supply** Ex. 0.25 mg/d for 6 mos-3 yrs if less than 0.3 ppm
47
# **STUDY** If an infant >6 months lives out in the country and is dependent on well water, what vitamin/mineral would you need to supplement?
Fluoride
48
# **STUDY** No cow milk prior to 1 year of age because it ... A. Is low in iron B. Is low in vitamins C & E C. Is low in essential fatty acids D. Has a high renal solute load E. A & C F. All of the above
F. All of the above ## Footnote Infants have limited ability to concentrate urine. Fluid may not be retained when infants are fed a high renal solute formula No more than 33 mOsm/100 kcal Formula: 20 mOsm/100 kcal Cow's milk: 45 mOsm/100 kcal
49
