Objetivo: O objetivo do presente estudo foi determinar o Gasto Energético Basal (GEB) através da Calorimetria Indireta (CI) em pacientes com carcinoma epidermóide de esôfago (CEE). Métodos: Estudo transversal com 30 pacientes internados com diagnóstico de CEE submetidos à CI antes de iniciar a terapia oncológica. A avaliação nutricional foi realizada a partir de parâmetros antropométricos (Índice de Massa Corporal, Circunferência do Braço, Dobra Cutânea Triciptal, Circunferência Muscular do Braço e Percentual de Perda de Peso), parâmetros bioquímicos (albumina, transferrina e Proteína C Reativa) e bioimpedância tetrapolar. Além disso, foram determinados a capacidade pulmonar e o estadiamento clínico. A CI foi realizada depois de uma noite de jejum. Valores de p < 0,05 foram considerados estatisticamente significativos. Resultados: A média do GEB pela CI foi de 1.421,8 ± 348,2 kcal e pela Equação de Harris e Benedict (EHB) de 1.310,6 ± 215,1 kcal. A EHB subestimou o GEB comparado com a CI (p= 0,014). Foi encontrada diferença significativa no GEB entre os pacientes desnutridos (1.181,7 ± 278,1 kcal) e bem nutridos (1.509,1 ± 334,1 kcal) pelo IMC (p=0,020). Pelo %PP não foram encontradas diferenças significativas entre o GEB dos pacientes com PP significativa e não significativa (p=0,526). Entre os pacientes que apresentavam o percentual de massa magra abaixo do esperado, foi encontrada GEB de 1.408,9 ± 364,3 kcal, enquanto que os que tinham o percentual de massa magra adequado o GEB foi de 1.538,4 ± 97,5 kcal (p=0,550). Não houve associação entre o GEB pela CI e o estadiamento (p=0,255) e o Índice de Tiffeneau (p=0,946). Na associação entre os exames laboratoriais e o GEB pela CI, não foram encontradas associações significativas entre os que tinham alteração e os que não a tinham (p= 0,364, 0,309 e 0,780, respectivamente). Conclusões: O GEB de pacientes com CEE foi subestimado pela EHB sem fator injúria e superestimado pela EHB com fator injúria de 1,3 quando comparado ao GEB medido pela CI. / Expenditure (BEE) of patients with squamous cell carcinoma (SCC) of the esophagus by indirect calorimetry (IC). Methods: Cross-sectional study involving 30 patients admitted with a diagnosis of SCC who underwent IC before starting cancer therapy. Nutritional assessment was conducted using anthropometric parameters (body mass index, arm circumference, triceps skinfold thickness, arm muscle circumference and percentage weight loss), biochemical parameters (albumin, transferrin and Creactive protein) and tetrapolar bioimpedance analysis. Additionally, lung capacity and clinical staging were determined. IC was carried out after overnight fasting. P values <0.05 were considered statistically significant. Results: The mean of the BEE for IC and Harris-Benedict equation were 1421.8 ± 348.2 kcal/day and 1310.6 ± 215.1 kcal/day, respectively. The HBE underestimated the BEE when compared with IC (p=0.014). A significant difference was found in the BEE between malnourished (1181.7 ± 278.1 kcal/day) and well-nourished (1509.1 ± 334.1 kcal/day) patients by BMI (p=0.020). In terms of percentage weight loss, no significant difference was found in BEE between patients with significant or non-significant weight loss (p=0.526). BEE for patients presenting with a lower than expected lean body mass was 1408.9 ± 364.3 kcal/day, whereas for those with an adequate lean body mass it was 1538.4 ± 97.5 kcal/day (p=0.550). No association was found between BEE measured by IC and clinical staging (p=0.255) or the Tiffeneau Index (p=0.946). Additionally, when comparing laboratory examinations with BEE measured by IC, no significant association was found between those with and those without alterations (p=0.364, 0.309 and 0.780 respectively). Conclusion: When compared to BEE measured by IC of patients with SCC, it was found that the HBE without injury factor underestimated, whereas the HBE with an injury factor of 1.3 overestimated BEE.

Objetivos: Medir o gasto e estimar a ingestão energética de adolescentes asmáticos com excesso de peso e comparar com asmáticos eutróficos e não asmáticos com excesso de peso. Metodologia: Estudo transversal incluindo 69 adolescentes de 10 a 18 anos. Foram comparados três grupos que foram pareados. Para avaliação nutricional utilizaram-se medidas antropométricas e de composição corporal. O gasto energético foi medido por calorimetria indireta e a ingestão energética estimada por inquéritos alimentares. Resultados: Cada grupo era composto por 23 adolescentes, sendo 13 do sexo masculino, com média de idade 12,39±2,40 anos. Os resultados a seguir são apresentados, respectivamente, para os grupos: asmáticos com excesso de peso; asmáticos eutróficos e não asmáticos com excesso de peso: índice de massa corporal (24,83 ± 2,73Kg/m2), (19,01 ± 2,10 Kg/m2) e (25,35 ± 3,66Kg/m2); gasto energético de repouso (GER) (1550,24±547,23Kcal/dia), (1540,82±544,22Kcal/dia) e (1697,24 ± 379,84Kcal/dia); estimativa da ingestão energética (2068,75± 516,66Kcal/dia), (2174,05± 500,55Kcal/dia) e (1673,17 ± 530,68Kcal/dia). O GER não foi estatisticamente diferente entre os grupos, mesmo quando ajustado pela massa magra e massa gorda (f=0,186; p=0,831). Somente nos grupos dos adolescentes asmáticos, a estimativa da ingestão energética foi maior que o GER. Conclusão: O GER foi semelhante entre os grupos. A estimativa da ingestão energética dos adolescentes asmáticos foi maior que o GER. / Objectives: To measure resting energy expenditure and calculate caloric intake of asthmatic adolescents with excess body weight and compare results with those of groups of adolescents eutrophic asthmatics and no-asthmatic adolescents with excess body weight. Methods: Cross-sectional study with 69 adolescents aged 10 to 18 years divided into three matched groups. Nutritional status was assessed using anthropometric and body composition measurements. Indirect calorimetry was used to measure energy expenditure; caloric intake was estimated from dietary recalls. Results: In each group, there were 23 adolescents (10 girls) aged 12.39±2.40 years. Results for each group (asthmatic adolescents with excess body weight; adolescents eutrophic asthmatics; and no-asthmatic adolescents with excess body weight) were, respectively: Body mass index = 24.83±2.73 kg/m2, 19.01±2.10 kg/m2, and 25.35±3.66 kg/m2; resting energy expenditure (REE) = 1550.24±547.23 kcal/day, 1540.82±544.22 kcal/day, and 1697.24±379.84 kcal/day; estimated caloric intake = 2068.75±516.66 kcal/day, 2174.05±500.55 kcal/day, and 1673.17±530.68 kcal/day. REE between groups was not statistically different, not even after correction for lean mass and fat mass (F=0.186; P=0.831). Estimated caloric intake was greater than REE only in the group of adolescents with asthma. Conclusion: REE was not significantly different between groups. Estimated caloric intake was greater than REE in the group of adolescents with asthma.

Vários estudos analisando a taxa de metabolismo de repouso (TMR) contribuíram com equações cuja proposta era estabelecer padrões que pudessem ser genericamente utilizadas para se estimar a TMR. A equação de Harris-Benedict (HB), permanece como o método mais comumente utilizado para estimar a TMR. Porém, em indivíduos obesos o uso de equações preditivas da TMR pode levar a resultados conflitantes. Indivíduos obesos submetidos a dietas hipocalóricas podem apresentar uma diminuição da TMR e do gasto energético total. Isto pode ser a causa da redução na velocidade da perda de peso durante o tratamento. Outros estudos mostram que a TMR, quando corrigida para a massa livre de gordura (MLG), apresenta pouca variabilidade e propõem uma correlação entre MLG e TMR. Porém ainda existem dificuldades em se afirmar ou não se a redução de massa corporal também reduz a TMR. O presente estudo teve como objetivos determinar a TMR de indivíduos com obesidade grau III (IMC > 40 kg/m2) do sexo feminino obtida por meio de calorimetria indireta (CI) e comparar com a TMR estimada por meio da equação de HB utilizando-se peso atual e peso ideal. Relacionar a TMR medida por CI com a composição corporal e validar a relação entre a TMR e a MLG nestes indivíduos antes e após a perda de peso. As pacientes foram internadas na Unidade Metabólica da Divisão de Nutrologia do Departamento de Clínica Médica do HCFMRP-USP, durante um período de 8 semanas. No início e no final do estudo foram realizadas: avaliação nutricional incluindo antropometria, bioimpedância e calorimetria indireta. As pacientes foram submetidas a uma dieta hipocalórica durante a internação. A TMR medida por calorimetria indireta (CI) no início e final do estudo foi de 2540 ± 417 e 1924 ± 275 kcal/dia, respectivamente (p<0,05). Quando calculado pela equação de HB utilizando-se peso atual, os valores encontrados foram 2074 ± 214 e 1941 ± 190 kcal/dia (p<0,05). Utilizando-se o peso ideal a TMR calculada foi de 1343 ± 59 kcal/dia. A TMR medida por CI foi, em média, 18 % maior que a calculada por HB pelo peso atual e 47 % maior que a calculada por HB utilizando-se o peso ideal no início do estudo. No final do estudo estes valores passaram para 1% e 30% respectivamente. Comparando-se a TMR medida por CI e calculada por HB usando peso atual tem-se, no início do estudo uma diferença significante (p<0,05) que não se repete no final do estudo (p>0,05). A TMR, quando corrigida para massa livre de gordura no início e no final do estudo foi de 46 ± 6 e 35 ± 5 kcal/d/MLG (p<0,05) respectivamente e quando corrigida para a gordura corporal (GC) foi de 33 ± 6 e 30 ± 5 kcal/d/GC (p<0,05) respectivamente. Os dados encontrados no presente estudo não permitem afirmar que o uso da equação de HB possa estimar a TMR de maneira confiável em indivíduos obesos grau III do sexo feminino. Porém os dados sugerem que logo após submeter esses indivíduos à dieta hipocalórica, com conseqüente perda de peso a equação de HB se torna confiável para estimar a TMR. Pacientes obesos ingerindo dieta livre deveriam ter a TMR obtida por meio da equação de HB corrigida por um fator de 20% a mais. / Studies analyzing resting energy expenditure (REE) have contributed with equations that were intended to establish a pattern that could be used generally to estimate the REE. Harris Benedict’s (HB) equation remains as the most used in estimating the REE. But in obese subjects, the use of predictive equations can lead to conflicting results. Obese individuals undergoing a hypo caloric diet may have a reduction in the REE and in the total energy expenditure. These are the most probably cause of the slowing on weight loss during the treatment. Some studies show that when the REE is relative to the fat free mass (FFM) there is less variability and their proposal is a correlation between FFM and REE. But it is difficult to confirm if a reduction in total body mass also can diminish the REE. The objective of this study was to define the REE of female subjects with grade III obesity (body mass index (BMI) > 40 kg/m2) using indirect calorimetry (IC) and to compare this REE with the one estimated with HB equation using real body weight and ideal body weight, and try to correlate the REE obtained by IC with the body composition, validating the relation between REE and FFM in these individual before and after weight loss. The patients were under hospital regimen in the Metabolic Unit of the Nutrology Division of the Internal Medicine Department of the HCFMRP-USP, for an 8 weeks period. At the beginning and at the end of the study, nutritional assessment was realized, including anthropometry, bioimpedance and indirect calorimetry. The patients were undergoing a hypo caloric diet during the 8 week period. The REE obtained by indirect calorimetry (IC) at the beginning and at the end of the study was 2540 ± 417 e 1924 ± 275 kcal/day, respectively (p<0,05). When estimated with the HB equation using real weight the values were 2074 ± 214 e 1941 ± 190 kcal/day (p<0,05). Using the ideal weight, the calculated REE was 1343 ± 59 kcal/day. At the beginning of the study, REE obtained by IC was 18 % greater than the REE calculated with HB equation using the real weight and 47 % greater than the one calculated using the ideal body weight. At the end of the study these values changed to 1% e 30% respectively. There is a significant difference (p<0,05) when comparing the REE obtained by IC with the one calculated using the HB equation with real weight at the beginning of the study, but this does not happen at the end of the study (p>0,05). The REE corrected by the FFM at the beginning and at the end of the study was 46 ± 6 e 35 ± 5 kcal/d/FFM (p<0,05) respectively and the REE corrected by the fat mass (FM) was 3 ± 6 e 30 ± 5 kcal/d/FM (p<0,05) respectively. The data found in this study does not allow affirming that the use of HB equation to predict REE in female grade III obese subjects is reliable. But the data suggest that immediately after using a hypo caloric diet, the REE calculated using HB equation and real weight is reliable. When calculating the REE of female grade III obese patients undergoing a free diet using HB equation, the obtained value should be increased in 20 %.

Os principais sinais e sintomas clínicos são dificuldade para engolir os alimentos, aumento do volume da região cervical, rouquidão, sangramento e em alguns casos dor que guiam o paciente à perda de peso. O presente estudo teve como objetivo avaliar o gasto energético basal e os fatores que mais influenciam na perda de peso de trinta e dois pacientes com carcinoma de células escamosas de cabeça e pescoço em estádios III e IV do sistema TNM antes e após 30 dias do término da radioterapia e quimioterapia,compreendidos numa faixa etária de 30 a 65 anos, de ambos os sexos. A seleção dos indivíduos foi realizada no ambulatório de Oncologia do Hospital das Clinicas -Universidade Estadual de Campinas. A coleta de dados realizou-se na Unidade Metabólica, 6° andar do HC-UNICAMP que englobou o preenchimento de um questionário com informações pessoais (idade, sexo, tabagismo), avaliação do estado nutricional (peso, altura e avaliação subjetiva global preenchida pelo próprio paciente), avaliação da composição corporal (bioempedância elétrica, circunferência braquial, prega cutânea do tríceps e circunferência muscular do braço), avaliação do gasto energético basal (calorimetria indireta), avaliação metabólica/bioquímica (colesterol total e frações, triglicérides, glicemia, insulinemia, adiponectina, leptina, fator de necrose tumoral (TNF-?), interleucina 1 (IL-1?), interleucina 6 (IL-6) e avaliação da sensibilidade à insulina (HOMA). Além disso os pacientes foram avaliados em relação à ingestão alimentar por meio do recordatório de 24 horas e do Índice de Alimentação Saudável. Os dados foram digitados em banco de dados utilizando-se o programa Excel e para a análise estatística utilizou-se o programa SAS para Windows versão 9.1.3. com nível de significância ? 5%. Nosso estudo mostrou que não podemos justificar a perda de peso pelo aumento do gasto energético basal e/ou diminuição do gasto energético basal, sendo a mesma influenciada por fatores derivados do tumor e pelo início de um processo inflamatório e sugerimos que o aporte nutricional precoce e a ressecção tumoral antes de iniciar o tratamento poderiam melhorar o prognóstico do paciente / Abstract: Worldwide, an estimated 644,000 new cases of head and neck cancer are diagnosed each year, with two- thirds of cases occurring in undeveloped countries. They are usually seen as a set of signs and symptoms which include lesions of the oral cavity, swelling of the neck, difficulty in swallowing food, hoarseness, bleeding and ultimately pain that in some cases can lead to malnutrition. Furthermore, the standard treatment increases weight loss. The main of this study was to evaluate the resting energy expenditure and the factors that had the most influence on weight loss of thirty two patients (aged between 30 and 65 years of both genders) with squamous cell carcinoma of head and neck in stage III and IV of the TNM system before and after 30 days of completion radiotherapy and chemotherapy. The selection of subjects was performed at the Hospital Oncology Clinic, University of Campinas. Data collection took place in the Metabolic Unit which included filling out a questionnaire with personal information such as (age, sex, smoker or non-smoker ...), assessment of nutritional status (weight, height and subjective global assessment completed by the patient), evaluation of body composition (bioelectrical impedance, arm circumference, triceps skinfold and arm muscle circumference), evaluation of resting energy expenditure (indirect calorimetry), evaluation of metabolic / biochemical factors (total cholesterol and fractions , triglycerides, glucose, insulin, adiponectin, leptin, tumor necrosis factor ? (TNF-?), interleukin 1 ? (IL-1?), interleukin 6 (IL-6) and evaluation of insulin sensitivity (HOMA). In addition, the patient was evaluated in relation to food intake by 24-hour recall and the Healthy Eating Index. The data were entered into the database using the program Excel and the statistical analysis used the SAS for Windows version 9.1. 3. with a significance level ? 5%. Our study demonstrated that we cannot justify the weight loss either by increasing the resting energy expenditure or decreasing; it is influenced by factors derived from the tumor and the beginning of an inflammatory process.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The objective of the study is to evaluate the effect of Acacia mearnsii tannin extract on balance of nutrients and efficiency of energy of steers. The experiment was conducted in a Latin Square design, with eight Holstein steers (338 ± 32,2 kg body weight (BW)). The animals have been housed in metabolism cages, fed on a diet composed by 90% corn silage and 10% concentrate at two levels of intake with or without the inclusion of Acacia mearnsii tannin extract. The treatment structure was a 2 × 2 factorial; intake, 1.2 versus 1.8 × NEm and tannin addition vs. control. The experiment was conducted in four periods of 21 days, of which the first 14 days were intended for the adaptation of the animals to the diets and the last 7 days to evaluate whole body energy balance and endogenous heat production. For measurement of heat production and nutrient balance, expired respiratory gases, urine, and feces were collected. Fecal and urine collections were taken during 7 days. Whole-body heat production (HP) was calculated by indirect calorimetry from O2 consumption and CO2 production and corrected for CH4 production and urinary N excretion using the equation proposed by Brouwer (1965). The inclusion of tannin extract had no effect on energy and nitrogen balance. The two levels of intake had effect on energy retention and whole-body heat production (P<0.001). / Este estudo foi conduzido com o objetivo de avaliar a inclusão de extrato tanífero de Acacia mearnsii a dois níveis de consumo da dieta total de bovinos sobre o balanço de nutrientes e eficiência da utilização de energia. Foram utilizados oito bovinos machos, castrados, da raça Holandês (338 ± 32,2 kg de peso corporal (PC), aleatoriamente alocados em um Quadrado Latino replicado em esquema fatorial 2 x 2 (com ou sem a inclusão de extrato tanífero x níveis de consumo). A dieta experimental foi composta de silagem de milho, milho moído e premix mineral, a relação volumoso:concentrado utilizada foi de 90:10. Foram ofertados dois níveis de consumo: 1,5 e 1,8 × Energia Líquida de mantença (Elm). O experimento foi constituído de quatro períodos de 21 dias cada, sendo 14 dias de adaptação às dietas e 7 dias de coleta de amostras. Coletas fecais e urinárias foram realizadas durante os 7 dias de coleta. A produção de calor foi calculada pela calorimetria indireta a partir do consumo de O2 e a produção de CO2 corrigido para a produção de CH4 e excreção de nitrogênio urinário utilizando equação proposta por Brouwer (1965). A inclusão do extrato tanífero não teve efeito sobre o balanço de energia e nitrogênio. Os níveis de ingestão influenciaram a retenção de energia e a produção de calor (P<0,001).

Introduction: Weight loss programs are based on inducing a negative energy balance by decreasing energy intake while increasing energy expenditure. Energy needs of obese patients are difficult to determine. The value of resting energy expenditure, as the largest component of the energy needs, is usually calculated to asses an adequate energy intake for obese patient. In clinical practice, predictive equations are most commonly used for this purpose, because of their simplicity, although many clinical studies have shown that in obese individuals they may generate errors large enough to impact the outcome of treatment. It leads to the prescription of an inadequate diet that does not meet the criterion of long-term sustainability. Objective: The aim of the thesis is to compare the values of resting energy expenditure (REE) measured by indirect calorimetry with values calculated with Harris-Benedict predictive equation in a selected group of obese individuals. Methods: The sample includes 38 subjects, 28 women and 10 men, patients of the General University Hospital in Prague. The average age is 48 ± 11,71 years, the mean BMI is 42,88 ± 9,09 kg/m2 . For each subject, resting energy expenditure was measured by indirect calorimetry and calculated by the Harris-Benedict predictive equation. Indirect...

Title: Movement economy and physiological response during differing climbing speeds in sport climbers. Aims: The work aims to evaluace climbing economy and physiological responses of intermediate and advanced climbers in different climbing speeds. Methodology: 32 climbers (11 advanced men, 11 intermediate men, 10 intermediate women) performed 3 submaximal tests in treadwall at slope of 90ř at speeds 4, 6 and 9 m.min-1 . Each of the tests lasted exactly 4 minutes. Oxygen consumption (VO2), heart rate (HR), ventilation (VE), respiratory ratio (RER) and energy expenditure were monitored. Results: Advanced men reported lower energy expenditure than intermediate men in all climbing speeds (4 m.min-1 : -0,06 kcal.kg-1 , P = 0,007; 6 m.min-1 : -0,06 kcal.kg-1 P = 0,048; 9 m.min-1 : -0,07 kcal.kg-1 P = 0,022). Intermediate women reported only slightly lower energy expenditure than intermediate men (4 m.min-1 : -0,01 kcal.kg-1 P = 0,051; 6 m.min-1 : 0,06 kcal.kg-1 P = 0,091; 9 m.min-1 : -0,03 kcal.kg-1 P = 0,115). Energy expenditure was significantly lower at 4 m.min-1 than at 6 m.min-1 (-9,82 kcal, p = 0,001) and also signicantly lower at 6 m.min-1 than at 9 m.min-1 (-8,3 kcal, p = 0,001). Advanced men reported significantly lower VO2 at speeds 4 a 6 m.min-1 (- 2,2 ml.kg- 1 .min-1, P = 0,022; -3,9 ml.kg-1...

Title Energy expenditure of slackline walking Objectives The aim of this study was to investigate the energy expenditure of slacklining in intermediate and advanced slackliners. Methods In this observatory study, 19 slackliners (10 intermediate, of which 7 men and 3 women, 9 advanced, of which 7 men and 2 women) completed experimental energy expenditure measurement of slacklining using indirect colorimetry. The MetaMax 3B metabolic analyzer (Cortex Biophysik, Germany) was used to determine respiratory parameters and the heart rate monitor (Polar Electro OY, Finland) was used to determine the heart rate (HR). Comparative statistical tools were used in the data analysis. Results Relative energy expenditure of 0,471 kJ·min-1 ·kg-1 was found in intermediate slackliners and 0,377 kJ·min-1 ·kg-1 in advanced slackliners in walking on a 10 m long slackline at a constant speed of 15 m·min-1 . In the static standing on slackline, the relative energy expenditure was found to be 0.368 kJ·min-1 ·kg-1 in intermediate slackliners and 0.289 kJ·min-1 ·kg-1 in advanced slackliners. The weighted arithmetic mean for HR in men and women walking on the slackline at 15 m·min-1 was at 67.3% of the predicted HRmax (220 - age for men, 226 - age for women). The MET value in the advanced group (n = 10) was set at 5.15, and in...

Introduction: Changes in eating habits and incorporation of physical activities remain to be the main methods in treating obesity. To set an adequate calorie intake, which would lead to weight loss, it is necessary to determine energy needs of an individual. For that energy intake and energy expenditure need to be determinate. However, energy expenditure is difficult to determine since it is contributed of three components. Basal, respectively resting metabolic rate (RMR), which is affected by a body composition, has the greatest influence on a total energy expenditure. Indirect calorimetry (IC) is considered to be a gold standard to determine RMR. When RMR is calculated by prediction equations instead, such as Harris-Benedict (H-B) equation, energy needs are overestimate or underestimate for people with abnormal body composition. Objectives: The aim of this study is to analyse data of RMR obtained using IC in connection to body composition. The main aim is to determine how fat free mas (FFM) and fat mass (FM) are affecting RMR in obese patients. There is also a comparation of RMR measured by the IC and RMR calculated using H-B equation as a part of this study, while IC is considered to be a reference method. Methods: Patients new to ambulance of obesitology at General University Hospital in Prague...
