Micronutrient intakes in enterally and orally fed children with severe cerebral palsy

Nutritional interventions in children and adolescents with cerebral palsy: systematic review

OBJECTIVE

To systematically review the literature in search of the most suitable and effective nutritional interventions and indications for the nutritional treatment of children and adolescents with cerebral palsy (CP).

DATA SOURCE

This review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The articles were selected from seven databases (Cochrane, Literatura Latino-Americana e do Caribe em Ciências da Saúde - Lilacs, Embase, United States National Library of Medicine - PubMed, Scientific Electronic Library Online - SciELO, Scopus, and Web of Science). Studies from a pediatric group (0 to 18 years old) diagnosed with CP were included and the search strategy included the descriptors: "children" OR "childhood" AND "nutritional therapy" OR "nutritional intervention" OR "nutrition" OR "nutritional support" OR "diet" AND "cerebral palsy" OR "cerebral injury". Methodological quality was assessed using the checklist for cross-sectional analytical studies, the Newcastle-Ottawa scale or the Cochrane Collaboration tool for clinical trials.

DATA SYNTHESIS

Fifteen studies (n=658) published from 1990 to 2020 met the inclusion criteria. All of them had a low risk of bias. The data showed that children and adolescents with CP have worse nutritional status than those normally developed. Those who received hypercaloric and hyperprotein nutritional supplementation benefited from its use. Studies indicate that enteral nutrition should be considered when nutritional needs are not met by the oral diet, especially in cases where oral motor functions are impaired. In addition, there was a direct relationship between the consistency of food, the level of motor function and nutritional status.

CONCLUSIONS

Children and adolescents with CP have a greater risk of malnutrition. The use of nutritional supplementation may help with weight gain. In addition, enteral nutrition and modification of food texture have been used to improve the nutritional status of this group.

Nutritional Interventions in Children with Brain Injuries: A Systematic Review

Background: Brain injury has several consequences throughout life, its increased incidence has caused great public concern. The aim was identifying the main nutritional therapies recommended for children with brain injuries. Methods: A systematic review was carried out using the terms in the search strategy: “Brain Injuries”, “Nutrition Therapy”, and “Child” and their synonyms, from database inception up to August 2020. The search was conducted in the following databases: MEDLINE, EMBASE, Scopus, Cochrane library, LILACS, and grey literature. Two reviewers independently selected the included studies, according to the eligibility criteria and extracted data from the included articles. Results: A total of 1196 studies resulted from electronic searches, and out of these, 27 studies were read in full and eight studies were included. For early enteral nutritional support (<48 h), results suggest benefit in increasing survival rates. Type of dietary protein seems to be related to decreasing gastric emptying by 40%. The use of fibers seems to reduce gastrointestinal discomfort and increase stool frequency. Conclusions: The evidence mapped was extracted from small studies analyzing different outcomes, so any decision making should be analyzed considering the context. We present the direction of the effect, but the magnitude is still unclear.

Serum trace element and amino acid profile in children with cerebral palsy

BACKGROUND

The existing data demonstrate that both trace elements and amino acids play a significant role in neurodevelopment and brain functioning. Certain studies have demonstrated alteration of micronutrient status in children with cerebral palsy, although multiple inconsistencies exist.

THE OBJECTIVE

of the present study was to assess serum trace element and mineral, as well as amino acid levels in children with cerebral palsy.

METHODS

71 children with cerebral palsy (39 boys and 32 girls, 5.7 ± 2.3 y.o.) and 84 healthy children (51 boys and 33 girls, 5.4 ± 2.3 y.o.) were enrolled in the present study. Serum trace element and mineral levels were assessed using inductively-coupled plasma mass-spectrometry (ICP-MS). Amino acid profile was evaluated by means of high-pressure liquid chromatography (HPLC).

RESULTS

Children with cerebral palsy are characterized by significantly lower Cu and Zn levels by 6% and 8%, whereas serum I concentration exceeded the control values by 7%. A tendency to increased serum Mn and Se levels was also observed in patients with cerebral palsy. Serum citrulline, leucine, tyrosine, and valine levels were 15 %, 23 %, 15 %, and 11 % lower than those in healthy controls. Nearly twofold lower levels of serum proline were accompanied by a 44 % elevation of hydroxyproline concentrations when compared to the control values. In multiple regression model serum I, Zn, and hydroxyproline levels were found to be independently associated with the presence of cerebral palsy. Correlation analysis demonstrated a significant correlation between Cu, Mn, Se, I, and Zn levels with hydroxyproline and citrulline concentrations.

CONCLUSION

The observed alterations in trace element and amino acid metabolism may contribute to neurological deterioration in cerebral palsy. However, the cross-sectional design of the study does not allow to estimate the causal trilateral relationships between cerebral palsy, altered trace element, and amino acid metabolism.

A Case-Control Study of Essential and Toxic Trace Elements and Minerals in Hair of 0-4-Year-Old Children with Cerebral Palsy

The objective of the present study was to assess hair essential and toxic trace elements and minerals in children with cerebral palsy in relation to age of the examinees. A total of 70 children with cerebral palsy and 70 healthy controls aged 0-4 years old were enrolled in the present study. The examined children were also divided into two age groups of those younger and older than 2 years old. Hair trace element content was assessed using ICP-MS at NexION 300D (PerkinElmer, USA). The obtained data demonstrate that hair boron was more than 2-fold lower in CP children as compared with the control group. At the same time, hair Na, Se, and V levels were 21%, 12%, and 20% lower when compared with healthy controls, respectively. It is also notable that a 9% and 28% decrease in hair Fe and Li levels respectively were nearly significant. The observed alterations were more profound in a younger group of patients. No significant group difference in hair toxic metal and metalloid levels was observed between the general cohorts of children with and without CP. In regression models, only hair Al and Ca contents were significantly associated with the presence of cerebral palsy, whereas hair Mg, Na, Ni, and Se levels were characterized as significant negative predictors. The observed alteration in trace element metabolism may also provide an additional link between cerebral palsy, psychomotor delay, and certain diseases, including diabetes, epilepsy, and osteoporosis. However, further studies using other substrates (blood, urine) or biomarkers are required.
