RESUMO

OBJECTIVE:: To compare nutritional risk in adult patients undergoing chemotherapy and radiotherapy in the beginning, middle, and end of oncologic treatment. METHOD:: This prospective, comparative study included 83 adult patients, 44 undergoing chemotherapy (CT group) and 39 undergoing radiotherapy (RT group) at an oncology treatment center. Nutritional risk was determined by NRS-2002 in the beginning, middle, and end of therapy. Statistical analysis was performed using Statistica 8.0 software. RESULTS:: No differences in food intake or body mass index were observed between the CT (24.6±4.8 kg/m²) and RT groups (25.0±5.9 kg/m², p=0.75). Weight loss in the preceding 3 months was detected in 56.8% of CT group and 38.5% of RT group (p=0.09). The weight loss percentage compared with the usual weight within 3 months was greater (p<0.001) in the CT (11.4±6.5%) than in the RT group (3.9±6.8%). In the beginning of treatment, we observed high percentages of patients at moderate (18.2 vs. 15.4%, p=0.73) and high nutritional risk (61.4 vs. 48.7%, p=0.25), with no statistical difference between the CT and RT groups, respectively. During therapy, the nutritional risk remained unaltered in both groups. In the end of therapy, the majority of patients were at moderate (18.2 vs. 12.8%, p=0.50) or severe nutritional risk (50.0 vs. 51.3%, p=0.91), in the CT and RT groups, respectively, regardless of the type of oncologic treatment. CONCLUSION:: The high prevalence of patients at moderate or high nutritional risk in the beginning of treatment indicates the need for an early and continuous follow-up of the nutritional status of patients undergoing oncologic treatment.

Resumo Objetivo: comparar o risco nutricional de pacientes adultos submetidos a quimio e radioterapia no início, no meio e ao término do tratamento oncológico. Método: estudo prospectivo e comparativo conduzido com 83 pacientes adultos de um centro de tratamento oncológico, sendo 44 sujeitos sob quimioterapia (grupo QTx) e 39 sob radioterapia (grupo RTx). O risco nutricional foi determinado pelo questionário NRS-2002 no início, ao meio e ao término da terapia. A análise estatística foi feita com o software Statistica 8.0. Resultados: não houve diferença no padrão de ingestão alimentar e no IMC (24,6±4,8 vs. 25±5,9 kg/m²; p=0,75) nos grupos QTx e RTx, respectivamente. Perda de peso nos 3 meses precedentes ocorreu em 56,8% dos pacientes sob quimioterapia e em 38,5% daqueles sob radioterapia (p=0,09). Os pacientes do grupo QTx apresentaram maior porcentagem de perda de peso em relação ao habitual em 3 meses (11,4±6,5 vs. 3,9±6,8%; p<0,001). No início do tratamento, houve alta taxa de risco nutricional moderado (18,2 vs. 15,4%; p=0,73) e grave (61,4 vs. 48,7%; p=0,25), sem diferença estatística entre os grupos QTx e RTx, respectivamente. No meio do tratamento, o risco nutricional foi mantido em ambos os grupos. Ao término da terapia, mais da metade dos pacientes apresentava risco nutricional moderado (18,2 vs. 12,8%; p=0,50) ou grave (50 vs. 51,3%; p=0,91), independentemente da modalidade de tratamento oncológico. Conclusão: a alta prevalência de risco nutricional moderado ou grave no início do tratamento aponta para a necessidade de abordagem nutricional precoce e permanente durante a terapia oncológica.

RESUMO

PURPOSE: This study aimed to determine Cu/Zn ratio, nutritional and inflammatory status in patients during the perioperative period for colorectal cancer. METHODS: The study included patients with histological diagnosis of colorectal adenocarcinoma (Cancer Group, n=46) and healthy volunteers (Control Group, n=28). We determined habitual food intake, body composition, laboratory data of nutritional status, serum calprotectin and plasma Cu and Zn concentrations. Mann-Whitney U-test was performed between-group comparisons and Spearman correlation test for correlations between the variables. RESULTS: Individuals in the Cancer Group presented significantly lower BMI, fat mass, plasma hemoglobin, total protein and albumin as compared with the Control Group. Serum calprotectin[70.1 ng/mL (CI95% 55.8-84.5) vs.53.3 ng/mL (40.3-66.4), p=0.05], plasma Cu concentrations [120 µg/dL(CI95% 114-126) vs. 106 µg/dL(CI95% 98-114), p<0.01] and the Cu/Zn ratio [1.59 (CI95% 1.48-1.71)vs. 1.35 (CI95% 1.23-1.46), p=0.01]were higher in patients with colorectal cancer than in controls. Additionally, the Cancer Group showed negative correlations between the Cu/Zn ratio and Zn intake, hemoglobin, serum albumin, and positive correlation between the Cu/Zn ratio and serum calprotectin. CONCLUSION: These results indicate that an increased plasma Cu/Zn ratio and serum calprotectin, and decreased protein values may be a result of the systemic inflammatory response to the tumor process.

RESUMO

Background/aims: micronutrient deficiency may contribute to a poorer control of diabetes. Thus, the objective of the present study was to assess the urinary excretion of micronutrients in patients with type 2 diabetes mellitus. Methods: patients with diabetes and controls were assessed regarding food intake, anthropometry, urinary loss of micronutrients and compared by the nonparametric Mann-Whitney test (p<0.05). Results: nine diabetic volunteers (52±14 years, BMI 30±11 kg/m² and abdominal circumference (AC) of 99±25 cm) and 9 control individuals (51±16 years, BMI 26±5 kg/m² and AC of 90±13 cm) were studied. Higher iron excretion was observed in the diabetic group and higher magnesium excretion in the control group. Conclusions: the type 2 diabetic patients here studied did not show increased micronutrient excretion in urine when compared to controls (AU)


Introducción/objetivos: la deficiencia de micronutrientes puede contribuir a un menor control de la diabetes. El objetivo de este estudio fue evaluar la excreción urinaria de micronutrientes en pacientes con diabetes mellitus tipo 2. Métodos: los pacientes con diabetes y los controles fueron evaluados por la ingesta de alimentos, la antropometría, la pérdida urinaria de micronutrientes y comparados por Mann Whitney no paramétrico (p<0,05). Resultados: fueron evaluados nueve sujetos diabéticos (52±14 años con un IMC de 30±11 kg/m² y la circunferencia de la cintura (CC) de 99±25 cm) y nueve sujetos control (51±16 años, IMC 26±5 kg/m² y CA total de 90±13 cm). La excreción de hierro más alta se observó en el grupo diabético y la mayor excreción de magnesio en el grupo de control. Conclusiones: el tipo 2 de pacientes diabéticos estudiados aquí no mostraron un aumento en la excreción de micronutrientes en la orina en comparación con los controles (AU)

RESUMO

OBJECTIVE: Bone loss has been established as a major extra-intestinal complication of short bowel syndrome (SBS). The purpose of this study was to correlate bone mineral density (BMD) with body mass index (BMI), serum vitamin and mineral levels in patients with SBS. MATERIAL AND METHODS: The study was conducted on 13 patients (8 male and 5 female, 54.7 ± 11.4 years) with SBS (residual small bowel length of 10 to 100 cm). We determined the food ingestion, anthropometry, serum levels of vitamins C, A, D, E and K, as well as serum and urinary levels of phosphorus and calcium. BMD was measured by dual-energy x-ray absorptiometry (DXA). RESULTS: Osteopenia and osteoporosis was diagnosed in all but one SBS patient. Serum levels of vitamin D were low in all volunteers. Sixty-one percent of patients had vitamin E deficiency; hypovitaminosis A and C occurred in one subject. BMI and C, E and K vitamin serum levels correlated with T-score of BMD. CONCLUSIONS: Osteopenia and osteoporosis were common in SBS patients. There was a correlation between BMD and the serum levels of vitamins C, E and K, an indicative that such vitamins may influence bone health.

RESUMO

BACKGROUND: Patients with short bowel syndrome have significant fluid and electrolytes loss. OBJECTIVE: Evaluate the mineral and electrolyte status in short bowel syndrome patients receiving intermittent parenteral nutrition or oral feeding. METHODS: Twenty two adults with short bowel syndrome, of whom 11 were parenteral nutrition dependent (PN group), and the 11 remaining had been weaned off parenteral nutrition for at least 1 year and received all nutrients by oral feeding (OF group). The study also included 14 healthy volunteers paired by age and gender (control group). Food ingestion, anthropometry, serum or plasma levels of sodium, potassium, phosphorus, magnesium, calcium, zinc, iron and copper were evaluated. PN group subjects were evaluated before starting a new parenteral nutrition cycle. RESULTS: The levels of sodium, potassium, phosphorus, calcium and zinc were similar between the groups. The magnesium value was lower in the PN group (1.0 ± 0.4 mEq /L) than other groups. Furthermore, this electrolyte was lower in the OF group (1.4 ± 0.3 mEq /L) when compared to the Control group (1.8 ± 0.1 mEq/L). Lower values of copper (69±24 vs 73±26 vs 109±16 µg/dL) were documented, respectively, for the PN and OF groups when compared to the control group. CONCLUSION: Hypomagnesemia and hypocupremia are electrolyte disturbances commonly observed in short bowel syndrome. Patients with massive intestinal resection require monitoring and supplementation in order to prevent magnesium and copper deficiencies.

Contexto Ressecções intestinais extensas resultam em perda de fluídos e eletrólitos. Objetivo Avaliar os níveis séricos de minerais e eletrólitos em pacientes com síndrome do intestino curto, dependentes ou não de nutrição parenteral. Métodos O estudo incluiu 22 adultos com síndrome de intestino curto, sendo 11 dependentes de nutrição parenteral (Grupo NP) e 11 sujeitos que recebiam todo aporte nutricional por via oral (Grupo VO). Foram incluídos 14 voluntários saudáveis, pareados para a idade e o gênero (Grupo Controle). A avaliação da ingestão alimentar, antropometria, níveis sanguíneos de sódio, potássio, fósforo, magnésio, cálcio, zinco, ferro e cobre foram documentados em todos os voluntários. Resultados Os níveis sanguíneos de sódio, potássio, fósforo, cálcio e zinco foram similares entre os grupos de estudo. Os níveis séricos de magnésio foram menores no Grupo NP (1,0±0,4 mEq/L) em relação aos demais grupos. Além disso, a concentração desse eletrólito foi menor no Grupo VO (1,4±0,3 mEq/L) em relação ao Grupo Controle (1,8±0,1 mEq/L). Foram documentados menores valores cobre (69±24 vs 73±26 vs 109±16 µg/dL) nos grupos NP e VO quando comparados com o Grupo Controle, respectivamente. Conclusão Hipomagnesemia e hipocupremia são distúrbios eletrolíticos comumente observados na síndrome de intestino curto. Os pacientes com ressecção intestinal extensa requerem monitorização e suplementação de magnésio e cobre a fim de prevenir deficiências. .

RESUMO

OBJECTIVE: To determine plasma homocysteine levels during fasting and after methionine overload, and to correlate homocysteinemia according to methylenetetrahydrofolate reductase (MTHFR) polymorphism in type 2 diabetic adults. SUBJECTS AND METHODS: The study included 50 type 2 diabetic adults (DM group) and 52 healthy subjects (Control group). Anthropometric data, and information on food intake, serum levels of vitamin B12, folic acid and plasma homocysteine were obtained. The identification of C677T and A1298C polymorphisms was carried out in the MTHFR gene. RESULTS: There was no significant difference in homocysteinemia between the two groups, and hyperhomocysteinemia during fasting occurred in 40% of the diabetic patients and in 23% of the controls. For the same polymorphism, there was not any significant difference in homocysteine between the groups. In the Control group, homocysteinemia was greater in those subjects with C677T and A1298C polymorphisms. Among diabetic subjects, those with the A1298C polymorphism had lower levels of homocysteine compared with individuals with C677T polymorphism. CONCLUSION: The MTHFR polymorphism (C677T and A1298C) resulted in different outcomes regarding homocysteinemia among individuals of each group (diabetic and control). These data suggest that metabolic factors inherent to diabetes influence homocysteine metabolism.

OBJETIVO: Determinar os níveis plasmáticos de homocisteína de jejum e após sobrecarga de metionina e correlacionar a homocisteinemia com o polimorfismo C677T e A1298C da metilenotetra-hidrofolato redutase (MTHFR) em diabéticos tipo 2. SUJEITOS E MÉTODOS: O estudo incluiu 50 adultos diabéticos tipo 2 (Grupo DM) e 52 indivíduos saudáveis (Grupo controle). Obtiveram-se os dados antropométricos, de ingestão alimentar, níveis séricos de vitamina B12, ácido fólico e homocisteína plasmática. Os polimorfismos C677T e A1298C foram identificados no gene da enzima MTHFR. RESULTADOS: Não houve diferença na homocisteinemia entre os grupos, embora a hiper-homocisteinemia de jejum tenha ocorrido em 40% dos diabéticos e 23% dos controles. Para o mesmo polimorfismo, não houve diferenças na homocisteinemia entre os grupos de estudo. Nos controles, a homocisteína foi maior entre aqueles com polimorfismos C677T e A1298C. Os diabéticos com polimorfismo A1298C apresentaram menores níveis de homocisteína quando comparados àqueles com polimorfismo C677T. CONCLUSÃO: Os polimorfismos da MTHFR (C677T e A1298C) resultaram em resposta distinta na homocisteinemia entre os indivíduos dentro de cada grupo (diabéticos e controles). Os dados sugerem que fatores metabólicos inerentes ao estado diabético influenciam o metabolismo da homocisteína.

RESUMO

BACKGROUND: Atrophy of the papillae, mucosa, and dorsum of the tongue are considered classical signs of nutritional deficiencies. OBJECTIVE: To assess the nutritional status of hospitalized alcoholics with or without papillary atrophy of the tongue. METHODS: This study was performed with 21 hospitalized alcoholics divided into Atrophic Glossitis Group (n=13) and Normal Tongue Group (n=8). Healthy, non-alcoholic volunteers composed the Control Group (n=8). Anthropometry and bioelectric impedance were performed, and serum vitamins A, E, and B12 were determined. RESULTS: There were no statistical differences in relation to age (46.7 ± 8.7 vs. 46.8 ± 15.8 years) or gender (92.3% vs. 87.5% male), respectively. Control Group volunteers were also paired in relation to age (47.5 ± 3.1 years) and male predominance (62.5%). In relation to hospitalized alcoholics without atrophic lesions of the tongue and Control Group, patients with papillary atrophy showed lower BMI (18.6 ± 2,5 vs 23.8 ± 3.5 vs 26.7 ± 3,6 kg/m(2)) and body fat content 7.6 ± 3.5 vs 13.3 ± 6.5 vs 19.5 ± 4,9 kg). When compared with the Control Group, alcoholic patients with or without papillary atrophy of the tongue showed lower values of red blood cells (10.8 ± 2.2 vs 11.8 ± 2.2 vs 14.5 ± 1,6g/dL) and albumin (3.6 ± 0.9 vs 3.6 ± 0.8 vs 4.4 ± 0.2g/dL). The seric levels of vitamins A, E, and B12 were similar amongst the groups. CONCLUSION: Hospitalized alcoholics with papillary atrophy of the tongue had lower BMI and fat body stores than controls, without associated hypovitaminosis.

RESUMO

PURPOSE: To evaluate the nutritional status of patients in the late postoperative period of pancreaticoduodenectomy (PD) and compare the long-term outcome according to pylorus-preserving (PPPD) or the standard technique (SPD) in which the pylorus is resected. METHODS: This prospective study was conducted twelve months prior or more in patients who had underwent PD (PD Group, n=15) and health volunteers (Control Group, n=15). At a post hoc analysis, the PD Group was divided in PPPD Subgroup (n=9) and SPD Subgroup (n=6), according to the PD techniques. Gastrointestinal complaints and nutritional status were evaluated, apart from a biochemical assessment; Student t-test or Mann-Whitney test were used. RESULTS: The patients recovered their body weight and the gastrointestinal complaints were uncommon. The PD Group showed higher energy and protein intake even though BMI was lower than in Control Group. There were no differences in laboratorial data, except for higher glycemia, serum alkaline phosfatase and C-reactive protein in PD Group. There was no difference in the various parameters evaluated when the Subgroups (PPPD and SPD) were compared. CONCLUSION: For long-term pancreaticoduodenectomy, the gastrointestinal symptoms are minimal and the patients had the clinical and nutritional status preserved, regardless of pylorus preservation.

RESUMO

BACKGROUND: Atrophy of the papillae, mucosa, and dorsum of the tongue are considered classical signs of nutritional deficiencies. OBJECTIVE: To assess the nutritional status of hospitalized alcoholics with or without papillary atrophy of the tongue. METHODS: This study was performed with 21 hospitalized alcoholics divided into Atrophic Glossitis Group (n=13) and Normal Tongue Group (n=8). Healthy, non-alcoholic volunteers composed the Control Group (n=8). Anthropometry and bioelectric impedance were performed, and serum vitamins A, E, and B12 were determined. RESULTS: There were no statistical differences in relation to age (46.7±8.7 vs. 46.8±15.8 years) or gender (92.3% vs. 87.5% male), respectively. Control Group volunteers were also paired in relation to age (47.5±3.1 years) and male predominance (62.5%). In relation to hospitalized alcoholics without atrophic lesions of the tongue and Control Group, patients with papillary atrophy showed lower BMI (18.6 ± 2,5 vs 23.8 ± 3.5 vs 26.7 ± 3,6 kg/m² ) and body fat content 7.6 ± 3.5 vs 13.3 ± 6.5 vs 19.5 ± 4,9 kg). When compared with the Control Group, alcoholic patients with or without papillary atrophy of the tongue showed lower values of red blood cells (10.8 ± 2.2 vs 11.8 ± 2.2 vs 14.5 ± 1,6g/dL) and albumin (3.6 ± 0.9 vs 3.6 ± 0.8 vs 4.4 ± 0.2g/dL). The seric levels of vitamins A, E, and B12 were similar amongst the groups. CONCLUSION: Hospitalized alcoholics with papillary atrophy of the tongue had lower BMI and fat body stores than controls, without associated hypovitaminosis.


FUNDAMENTOS: A deficiência crônica de nutrientes pode levar à hipotrofia das papilas e da mucosa e do dorso da língua, considerada um sinal clássico de subnutrição protéico-energética. OBJETIVO: O objetivo do presente estudo é comparar o estado nutricional, incluindo as dosagens dos níveis séricos de vitaminas A, E e B12 em pacientes alcoolistas com ou sem alterações tróficas das papilas linguais. MÉTODOS: O estudo caso-controle incluiu 21 pacientes adultos alcoolistas internados em um hospital universitário. Utilizando-se de um sistema de fotografia da cavidade oral, dois clínicos independentes classificaram os indivíduos alcoolistas de acordo com a presença ou não de alterações tróficas na língua. Foram registrados os dados antropométricos, a composição corporal pela impedância bioelétrica e os exames laboratoriais para avaliação clínica e nutricional, incluindo dosagens das vitaminas A, E e B12. O estudo incluiu ainda voluntários saudáveis, não alcoolistas como Grupo Controle (n=8). A comparação entre os grupos foi feita por ANOYA-F ou pelo teste de Kruskal-Wallis, de acordo com a curva de normalidade dos resultados. Foram considerados significativos diferenças com p < 0,05. RESULTADOS: De acordo com a presença de alterações tróficas nas papilas linguais, os pacientes alcoolistas foram alocados no Grupo Língua Despapilada (n=13) e Grupo Língua Normal (n=8), sem diferença estatística quanto à idade (46,7 ± 8,7 vs 46,8 ± 15,8 anos) e gênero masculino (92,3 vs 87,5%). Os voluntários do Grupo Controle apresentaram 47,5 ±3,1 anos, sendo 62,5% do gênero masculino. Os pacientes alcoolistas com hipotrofia papilar apresentaram menor IMC (18,6 ± 2,5 vs 23,8 ± 3,5 vs 26,7 ± 3,6 kg/m2) e gordura corporal (7,6 ± 3,5 vs 13,3 ± 6,5 vs 19,5 ± 4,9 kg), quando comparados com os demais grupos. Em relação ao Grupo Controle, os alcoolistas apresentaram menores valores de hemoglobina (10,8 ± 2,2 vs 11,8 ± 2,2 vs 14,5 ± 1,6 g/dL) e albumina sérica (3,6 ± 0,9 vs 3,6 ± 0,8 vs 4,4 ± 0,2 g/dL). Os níveis plasmáticos de vitaminas A, E e B12 foram similares entres os grupos. CONCLUSÃO: Os pacientes alcoolistas com achados físicos de hipotrofia de papilas linguais apresentam menores valores em medidas antropométricas, de hemoglobina e albumina séricas que os grupos Controle ou de alcoolistas sem língua despapilada. Não houve evidências de hipovitaminoses associadas.

OBJETIVO: Avaliar o estado nutricional de pacientes em pós-operatório tardio de pancreaticoduodenectomia (PD) e comparar a evolução de acordo com a preservação de piloro (PPPD) ou pela técnica padrão com ressecção do piloro (SPD). MÉTODOS: O estudo prospectivo foi conduzido com pacientes submetidos à PD após período mínimo de 12 meses (Grupo PD, n=15) e voluntários saudáveis (Grupo Controle, n=15). Numa análise posterior, o Grupo PD foi dividido em Subgrupo PPPD (n=9) e Subgrupo SPD (n=6), de acordo com a técnica de PD. Foram avaliadas as queixas digestivas, o estado nutricional e dados bioquímicos; a análise estatística foi realizada por meio do teste t-Student ou Mann-Whitney. RESULTADOS: Os pacientes recuperaram o estado nutricional e as queixas gastrointestinais foram incomuns. A ingestão protéica e energética foi maior no Grupo PD, apesar do menor IMC. Não houve diferenças em relação aos exames laboratoriais, exceto pelos maiores níveis de glicemia, fosfatase alcalina sérica e proteína C-reativa no Grupo PD. Quando os Subgrupos PPPD e SPD foram comparados, não houve diferenças nos diversos parâmetros analisados. CONCLUSÃO: No pós-operatório tardio de pancreaticoduodenectomia, os sintomas gastrointestinais são mínimos e o estado clínico e nutricional é adequado, independente da preservação do piloro.

RESUMO

PURPOSE: To compare vitamin levels, inflammatory and oxidative stress markers before and after skin autograft surgery to correct burn scar areas. METHODS: This prospective study was conducted with 8 patients with a median age of 28 years (range, 16 to 40 years) that had burn sequelae and were admitted to a Burn Unit for correction of small burn scar areas [3.3 (1.0-5.0) % of the corporal surface]. The volunteers were evaluated before and 48 hours after excision of scar tissue and skin autograft. Routine laboratory data, along with a food questionnaire and anthropometry were collected in the preoperative period. Serum vitamin A, C, E, B(12) and folic acid levels, inflammatory markers (C-protein reactive, alpha-1-acid glycoprotein, ferritin) and oxidative stress markers (reduced glutathione - GSH and Thiobarbituric Acid Reactive Substances - TBARS) were determined at preoperative and postoperative phases. Data were analyzed with two-sample Wilcoxon test. RESULTS: All volunteers were clinically stable and had adequate nutritional status at admission. After surgery, C-reactive protein serum levels increased [0.4 (0.01-1.0) vs. 2.5 (0.6-4.7) mg/dL, p=0.01] and vitamin A levels decreased [3.4 (2.1-4.2) vs. 2.4 (1.6-4.1) µmol/L, p=0.01]. No changes occurred in other vitamins, ferrritin, alpha-1-acid glycoprotein, GSH and TBARS levels. CONCLUSION: Minimal metabolic changes were produced after skin autograft in small areas of well-nourished patients without active infection or inflammation.
