Abstract Introduction Nutritional support is an essential component of caring for burn patients. Burns can induce a hypermetabolic state greater than twice the normal metabolic rate which can lead to higher rates of lean tissue mass breakdown. Despite its importance, there is no clear gold standard for monitoring nutritional status in the burn and critical care population. Many current methods of assessing body composition can be costly, labor-intensive, and inaccurate. Bioelectrical impedance analysis (BIA) is a promising new technology for assessing body composition that functions by sending a low-voltage current through the body and measuring the impedance to that current. Parameters derived from BIA have been demonstrated to reflect cellular health and correlate with nutritional status. The use of BIA to assess nutritional status in the critical care and burn population has not been well investigated. Thus, we have conducted a systematic review of the use of BIA to assess nutritional status in critically ill adults. Methods A search was conducted on Pubmed and Google Scholar in accordance with PRISMA guidelines between June 2020-August 2020 utilizing the keywords: bioelectrical impedance analysis, critical care, critical, nutrition, body composition, lean body mass, phase angle, water, fluid. Inclusion criteria were articles investigating the relationship between BIA and nutritional status in critically ill adults. Reviews, non-English articles, and studies involving pediatric patients were excluded. Results Our final study included 14 articles. BIA measured muscle mass was compared to a CT scan in two studies, with both reporting a statistically significant correlation. One article compared the ability of BIA and ultrasound to assess muscle mass, and this relationship was statistically significant. BIA derived phase angle was compared to NUTRIC and Subjective Global Assessment scores in four articles with all four reporting significant correlations. BIA was also compared to biochemical markers of nutrition such as albumin and two of three articles found significant correlations. One article compared BIA with gas exchange measured by indirect calorimetry and found that BIA could accurately assess body cell mass. No articles were found comparing BIA with other common nutritional markers such as prealbumin or nitrogen balance. Conclusions BIA shows promise as a method of assessing body composition and nutritional status in the critically ill patient population.

Abstract Introduction Bioelectrical impedance analysis (BIA) is a simple, noninvasive method of assessing body composition. BIA operates by sending a low-voltage electric current through the body and measuring the impedance to that current. Parameters obtained from BIA have been used to investigate a range of variables such as nutrition and hydration status in a variety of patient populations. Phase angle is also a unique parameter that is thought to reflect cellular health. BIA parameters can undergo further analysis by bioelectrical impedance vector analysis (BIVA) which can provide information about hydration status. Burn and critical care patients pose a unique challenge because they are particularly sensitive to fluid shifts and metabolic derangements which are associated with poorer outcomes. The utility of BIA and BIVA in this patient population has not been well studied. Thus, we have conducted a systematic review and meta-analysis of the ability of BIVA and BIA parameters to assess cellular health and hydration status in critically ill adults and whether they can be correlated with outcomes. Methods A search was performed on PubMed and Google Scholar in accordance with PRISMA guidelines between June 2020-August 2020 utilizing the keywords: bioelectrical impedance analysis, critical care, critical, body composition, phase angle, water, fluid. Inclusion criteria were articles investigating the relationship between BIA, BIVA and outcomes with regards to phase angle, hydration, and fluid status in critically ill adults. Reviews, non-English articles, and studies involving pediatric patients were excluded. A meta-analysis was conducted on the correlation between mean phase angle and mortality. Results The final analysis included 21 articles; 4 articles were included in the meta-analysis. Statistically significant correlations were found between phase angle and mortality in 9/13 articles, hospital length of stay in 4/7 articles, ICU length of stay in 5/7 articles, and mechanical ventilation duration in 1/4 articles. For meta-analysis, mean phase angle in survivors and non-survivors was 4.5 and 3.9 respectively, and this difference was statistically significant (Figure 1, p< 0.01). Significant correlations were found between ECW/TBW and mortality in 4/7 articles, and BIVA derived hydration status and mortality in 6/7 articles. Conclusions BIA and BIVA may be used as a prognostic indicator for outcomes in critical care patients. Further investigations are needed to explore this relationship in the burn patient population.

Body composition assessment is an important tool in both clinical and research settings able to characterize the nutritional status of individuals in various physiologic and pathologic conditions. Health care professionals can use the information acquired by body composition analysis for the prevention and treatment of diseases, ultimately improving health status. Here we describe commonly used techniques to assess body composition in healthy individuals, including dual-energy x-ray absorptiometry, bioelectrical impedance analysis, air displacement plethysmography, and ultrasonography. Understanding the key underlying concept(s) of each assessment method, as well as its advantages and limitations, facilitates selection of the method of choice and the method of the compartment of interest.

Abstract Nutrition has an important role in the management of inflammatory bowel disease (IBD) and metabolic syndrome (MS). The goal of this study was to assess the nutritive status of patients treated with IBD and metabolic syndrome in the Gastroenterology Centre, Pauls Stradiòð Clinical University Hospital. Body bioelectrical impedance analysis (BIA) using GENIUS 220 PLUS (Jawon Medical) was used to determine Body Mass Index (BMI) kg/m², Metabolic Body Fat (MBF) kg, Soft Lean Mass (SLM) kg, Total Body Water (TBW) kg, body composition, metabolic type, Basal Metabolic Rate (BMR) kcal, and total Energy Expenditure (TEE) kcal in patients with IBD and metabolic syndrome and in a similarly aged control group. The obtained data showed that BMI was not correlated with MBF, BTW and Lean Body Mass (LBM). Patients with Crohn’s disease (CD) had normal value of BMI (M 24.3 kg/m²; F 20.2kg/m²), but we found variety-specific differences in body composition that confirmed deficiency or increase of specific body parameters. The performed prospective study confirmed the importance of the more precise nutritional status analysis, as it was clinically useful for the nutritional management of IBD. Patients with CD had expressed nutrient deficiency, sarcopenia, and reduced amount of proteins and minerals. For patients with MS, sarcopenia was present despite obesity.

Anthropometric Indicators

Children with spastic cerebral palsy (CP) are at risk of undernutrition, which increases with the severity of movement disorders. Objective of the study: to assess and compare anthropometric indicators and body composition in children with cerebral palsy, depending on the level of impairment of gross motor function classification system (GMFCS). Materials and methods of research: 102 children were included in a prospective open-label comparative single-center non-randomized study: 58 (56.8%) boys and 44 (43.1%) girls with cerebral palsy aged 2 years to 16 years and 9 months who were undergoing rehabilitation in the National Medical Research Center of Children's Health in the period from 2019 to 2021. Anthropometric measurements (body weight, length, knee height, triceps and subscapular skinfold thicknesses) were performed on admission. Body fat percentage (%FM) was calculated by CP-modified (Gurka) equations and compared with results obtained using bioelectrical impedance analysis. A survey on the EDACS scale was performed to determine the ability to eat and drink. Results: patients were divided into 2 groups: the main group – 53 children (52%) with GMFCS levels IV–V and a comparison group – 49 children (48%) with GMFCS levels I–III. The groups did not differ statistically significantly in terms of gender (p=0.956) and age (p=0.207). The median age in the main group was 7.1 years, in the comparison group – 5.3 years. Children of the main group had statistically significantly lower growth indicators (HAZ1 –1.5 [–2.6; –0.74] and HAZ2 –0.58 [–1.59; 0.44], p=0.003), BMI (BAZ1 –2.43 [–3.67; –0.93]; BAZ2 –0.91 [–1.942; 0.28], p<0.001), higher frequency of oromotor dysfunction (42% and 4%, p< 0.001), the percentage of severe wasting (59% and 16%, p<0.001; OR 7.2 (95% CI 2.8–18.4) (p<0.001). There was no significant difference in %FM between children of main and comparison groups. Patients even with moderate and severe undernutrition according to WHO criteria had normal or excess %FM. A moderate positive correlation was found between %FM calculated using the Gurka equations and those obtained by bioelectrical impedance analysis (r=0.565, p=0.002). Conclusions: anthropometric indicators in children with CP deteriorate with an increase in the degree of neurological deficit. The use of BMI as the only marker of nutritional status is insufficient to properly diagnose of undernutrition and identify patients needed in nutritional interventions. For an adequate analysis of the nutritional status of children with CP, it is necessary to assess the body composition (measurement of the skinfold thicknesses or bioelectrical impedance analysis).
