Introduction: It is estimated that about 60% of patients with head and neck cancer (HNC) show poor nutritional status, and approximately 80% lose weight during treatment. The impact of surgical procedures on the risk of further weight loss, severe malnutrition, and cachexia is a significant clinical problem that determines the higher incidence of postoperative complications, reduced effectiveness of the treatment used, longer hospitalization time, poor quality of life, and higher mortality among patients. Bioelectrical impedance analysis (BIA) is currently recognized as a useful method of assessing the body composition and therefore the nutritional status of cancer patients. Aim: The aim of this study is to investigate whether measured and calculated parameters of BIA change shortly after surgery and could reflect the “health” of cells and body composition changes. Materials and methods: We enrolled 54 patients (males) with advanced HNC in this observational study. We collected detailed anthropometric and BIA-derived data. The Subjective Global Assessment (SGA) was used to assess nutrition. Results: In the assessment performed one week after surgery, compared to the condition on the day of surgery, the patients had significantly lower values of nutritional status (weight; body mass index – BMI; SGA), body composition (free fat mass – FFM; intracellular fluid –ICF; total body water – TBW). Other changes include a significant increase in fat mass (FM) or extracellular fluid (ECF). Moreover, a significant reduction of phase angle (PA, one of the most important BIA-derived prognostic factors) was also noted. Conclusions: Apart from the baseline assessment of the body composition and diagnosing nutritional disorders, it seems that BIA should be considered also in the monitoring of HNC patients undergoing surgery.

Background: Cystic fibrosis(CF),despite much progress in therapy, remains the disease which affects nutrition. Nutrition is an important prognostic factor of the outcome of the disease. We want to evaluate physical development, nutrition and body composition in CF children. Material and methods: 75 children diagnosed with CF (9 months to 18 years old) were included into the study. 33 healthy children (9 months to 18 years old) constituted the control group. The study consisted of 2 stages. In the first the differences between groups were investigated. The second, took place a year later. At each time point the following measurements were performed: height, body mass, skin fold, arm circumference; BMI, FFM%, FM% and Frisancho index. FFM(fat free mass), FM(fat mass), muscle mass, TBW(total body water) were evaluated by mans of BIA(bioimpedance). Results: CF children were shorter than healthy children. Stunting affected 18,67% of CF patients at first examination and 21,6% a year later. Underweight was diagnosed in 28% of patients at the beginning and in 41.2% a year after. Underweight was the result of both little FM and scarce muscle mass. Conclusions: Many children with cystic fibrosis suffers from short stature and underweight, which progresses within time. FFM decreases with the disease progress

WSTĘP: Do określenia tzw. suchej masy ciała zastosowano metodę bioimpedancji elektrycznej (BIA). Głównym celem pracy była ocena przydatności oznaczania suchej masy ciała za pomocą bioimpedancji elektrycznej u przewlekle dializowanych dzieci i młodych dorosłych, w tym w szczególności w odniesieniu do wybranych wykładników biochemicznych i parametrów układu sercowo-naczyniowego. Dodatkowo w tej grupie pacjentów, przy użyciu BIA, analizowano stan odżywienia. MATERIAŁ I METODY: Badaniem objęto 17 dzieci i młodych dorosłych w wieku od 6 do 24 lat (średnio 15 ± 3,5 roku), leczonych przewlekle hemodializą lub dializą otrzewnową. Oceniono wartości ciśnienia tętniczego, badania biochemiczne, parametry sercowe i wyniki z bioimpedancji w badaniu wyjściowym i po 2 miesiącach, po modyfikacji leczenia dializacyjnego w oparciu o parametry BIA. WYNIKI: Badane parametry ciśnienia tętniczego (skurczowe, rozkurczowe, średnie, tętna) było istotnie niższe podczas drugiego badania w porównaniu z wartościami wyjściowymi. Stężenie hemoglobiny było istotnie wyższe po 2 miesiącach obserwacji. W badaniu echokardiograficznym wykazano istotny wzrost frakcji wyrzutowej lewej komory, przy niezmienionych parametrach anatomicznych serca. Oceniane wskaźniki odżywienia – tkanki beztłuszczowej (LTI) i tłuszczowej (FTI) – nie uległy zmianie. Wykazano dodatnią korelację LTI z ciśnieniem tętniczym i niektórymi para-metrami z badania echokardiograficznego. WNIOSKI: Bioimpedancja elektryczna, jako prosta do przeprowadzenia i nieinwazyjna metoda, może być przydatna do precyzyjnego wyznaczania tzw. suchej masy ciała u dializowanych dzieci i młodych dorosłych. Adekwatne odwodnienie pacjentów pozwala na normalizację ciśnienia tętniczego krwi, co wiąże się z poprawą funkcji i prawdopodobnie stanu anatomicznego mięśnia sercowego. BIA pozwala także na dokładniejszą ocenę stanu odżywienia dializowanych chorych i wcześniejsze wykrycie niedożywienia, co w przypadku populacji pediatrycznej ma znaczenie rokownicze.

INTRODUCTION: Electrical bioimpedance (BIA) is used to estimate a patient's dry weight. The main goal of the study was to assess the usefulness of BIA in evaluating dry weight in children and young adults on chronic dialysis, with relation to selected biochemical and cardiovascular parameters. An additional goal was to analyze the state of nutrition by means of BIA. MATERIAL AND METHODS: 17 children and young adults, aged from 6 to 24 years (mean 15 ± 3.5 years) on hemodialysis or peritoneal dialysis, were examined. We estimated the arterial blood pressure, biochemical results, echocardiographic and bioimpedance parameters during the initial examination. Based on these results, modifications in the dialysis treatment were introduced. The follow-up examination was performed after 2 months. RESULTS: Arterial blood pressure values were significantly lower at the time of the second examination compared to the first one. The hemoglobin levels were higher after 2 months of observation. In the echocardiographic results, only the EF% improved. The Lin Tissue Indexes (LTI) and the Fat Tissue Indexes (FTI) were similar in both examinations. We observed positive correlations between LTI and arterial blood pressure and some echocardiographic parameters. CONCLUSION: The arterial blood pressure values were significantly lower at the time of the second examination compared to the first one. The hemoglobin levels were higher after 2 months of observation. In the echocardiographic results, only the EF% improved. The Lin Tissue Indexes (LTI) and the Fat Tissue Indexes (FTI) were similar in both examinations. We observed positive correlations between LTI and arterial blood pressure and some echocardiographic parameters.
