Doença de Madelung: abordagem cirúrgica combinada de lipectomia e lipoaspiração / Madelung's disease: combined surgical approach of lipectomy and liposuction

A doença de Madelung (DM) ou lipomatose simétrica múltipla é uma patologia caracterizada pelo acúmulo de tecido adiposo não encapsulado e depositado simetricamente ao redor do pescoço e tronco superior (tipo I - forma mais comum). Sua etiologia ainda é pouco esclarecida, porém apresenta evidente associação com o consumo crônico excessivo de bebidas alcoólicas. As deformidades físicas são o que levam o paciente a buscar serviço médico, juntamente com eventuais sintomas de acometimento cervical como redução de mobilidade e afecções respiratórias. O diagnóstico da lipomatose simétrica múltipla é clínico, podendo ser complementado com exame de imagem para afastar demais hipóteses diagnósticas e avaliar a extensão do acometimento. O tratamento pode ser realizado por duas modalidades: clínico ou cirúrgico (lipectomia ou lipoaspiração). Relata-se o caso de paciente com lipomatose simétrica múltipla tipo I abordado cirurgicamente com ambas as técnicas: lipectomia cervical e lipoaspiração abdominal. Paciente evoluiu de maneira satisfatória, com redução de queixas e sem recidivas até o presente momento.

Madelung's disease or Multiple Symmetric Lipomatosis is a condition characterized by the accumulation of unencapsulated adipose tissue deposited symmetrically around the neck and upper trunk (type I - most common form). Its etiology is still unclear, but it is clearly associated with chronic excessive consumption of alcoholic beverages. Physical deformities lead the patient to seek medical care, along with possible symptoms of cervical involvement such as reduced mobility and respiratory disorders. Multiple Symmetric Lipomatosis diagnosis is clinical and can be complemented with imaging to rule out other diagnostic hypotheses and assess the extent of involvement. Treatment can be performed in two ways: clinical or surgical (lipectomy or liposuction). We report the case of a patient with Multiple Symmetric Lipomatosis type I surgically treated with both techniques: cervical lipectomy and abdominal liposuction. The patient evolved satisfactorily, with a reduction in complaints and no recurrences so far.

Reconstrução de couro cabeludo com retalho expandido / Scalp reconstruction with expanded flap

Introdução: A presença de defeitos extensos em couro cabeludo apresenta-se como um grande desafio reconstrutor para o cirurgião plástico. Estes defeitos têm vasta etiologia como: traumática, queimaduras térmicas ou elétricas, ressecções tumorais benignas e malignas ou congênitas, sequelas de tratamentos radioterápicos e infecções. Destacando-se lesões como o escalpelamento e queimaduras (térmicas ou elétricas), geram repercussões significativas como a perda de tecido grave, osteomielite crônica ou sequelas menores como uma alopecia cicatricial. O objetivo deste trabalho é relatar um caso de reconstrução de couro cabeludo em fase tardia com expansor tecidual e posterior retalho de avanço, devido à alopecia cicatricial, em paciente feminina de 11 anos vítima de escaldamento por água quente em região frontotemporal direita. Métodos: Foi realizada análise retrospectiva de prontuário da paciente em questão. O presente trabalho segue os padrões do comitê de ética de Helsinque. Conclusão: A técnica de expansão tecidual de couro cabeludo por estágios e posterior confecção de retalho de avanço de escalpo demonstrou ser eficaz de restaurar a estrutura pilosa e linha da implantação capilar da paciente com mínima distorção local, restituindo a forma e a estética do couro cabeludo da paciente.

Introduction: The presence of extensive scalp defects is a major reconstructive challenge for the plastic surgeon. These defects have a vast etiology, such as traumatic, thermal or electrical burns, benign and malignant or congenital tumor resections, radiotherapy treatments sequelae, and infections. Noting that injuries such as scalping and burns (thermal or electrical), generate significant repercussions such as severe tissue loss, chronic osteomyelitis or minor sequelae such as scar alopecia. This study aims to report a case of late scalp reconstruction with a tissue expander and posterior advancement flap, due to cicatricial alopecia, in an 11-year-old female, victim of scalding by hot water in the right frontotemporal region. Methods: It was performed a retrospective analysis of the patient's medical record. The present work follows the standards of the Helsinki ethics committee. Conclusion: The scalp tissue expansion technique by stages and subsequent scalp advancement flap performing proved to be effective in restoring the patient's hair structure and hairline with minimal local distortion, restoring the scalp's shape and aesthetics of the patient.

Do more overweight patients at admission lose weight during hospitalization?

AIMS: Investigate in-patients weight loss during hospital stay. METHODS: In a retrospective study carried out with 170 inpatients, weight loss during hospitalization and its relationship with the type of disease, diet therapy, subjective global assessment (SGA), nutritional risk screening (NRS), anthropometry and hospitalization time (HT) were investigated. The Chi-square test, the Mann-Whitney and the univariate and multiple Cox regression analysis were used. RESULTS: During hospitalization 41.18% patients experienced weight loss. Patients who were overweight experienced a higher rate of weight loss while in the ward (45.7% of patients; p = 0.0179). Patients who were overweight, were twice as likely to lose weight during hospitalization, when compared with those who were already underweight (p= 0.0339; HR = 2.312; CI % = 1.066; 5.018). The age, gender, disease, diet prescribed during hospitalization, SGA, NRS, anthropometry and fasting time were not considered risk factors associated with weight loss. CONCLUSION: There was no influence of the dietary therapy type on weight loss. Only those patients who were overweight according to BMI were more associated to lose weight during hospitalization

NUTRITIONAL INDICATORS OF MALNUTRITION IN HOSPITALIZED PATIENTS.

BACKGROUND: Malnutrition is associated with clinical factors, including longer hospital stay, increased morbidity and mortality and hospital costs. OBJECTIVE: To investigate the prevalence of malnutrition using different nutritional indicators and to identify factors that contribute to malnutrition in hospitalized patients. METHODS: We investigated anthropometric, laboratory standards, nutritional risk screening (NRS), subjective global assessment (SGA), mini nutritional assessment and habitual energy consumption (HEC). Chi-square, Fisher's exact test, Mann-Whitney test and univariate and multiple Cox regression analysis were used, at 5% significance level. RESULTS: It was found 21.01% of malnourished individuals by ASG; a total of 34.78% with nutritional risk according to NRS and 11.59% with low weight (BMI). There was no statistically significant difference in the prevalence of malnutrition by ASG (P=0.3344) and nutritional risk by NRS (P=0.2286), among the types of disorders. Patients with nutritional risk were of higher median age (64.5 vs 58.0 years; P=0.0246) and had lower median values of HEC (1362.1 kcal vs 1525 kcal, P=0.0030), of calf circumference (32.0 cm vs 33.5 cm, P=0.0405) of lymphocyte count (1176.5 cell/mm3 vs 1760.5 cell/ mm3, P=0.0095); and higher percentage of low body weight according to the BMI (22.9% vs 5.6%; P=0.0096). Lymphocyte count was associated with nutritional risk (P=0.0414; HR= 1.000; IC95%= 0.999; 1.000). CONCLUSION: NRS was more sensitive than other indicators in the diagnosis of malnutrition. Patients at risk were older and had lower HEC values, calf circumference, BMI and lymphocyte count. Low lymphocyte count was considered a factor associated with nutritional risk by the NRS.

RESUMO CONTEXTO: A desnutrição está associada a fatores clínicos, incluindo maior tempo de internação, aumento da morbimortalidade e custos hospitalares. OBJETIVO: Investigar a prevalência de desnutrição por diferentes indicadores nutricionais e identificar fatores que contribuem para a desnutrição em pacientes hospitalizados. MÉTODOS: Investigou-se indicadores antropométricos, laboratoriais, nutritional risk screening, avaliação subjetiva global (ASG), mini avaliação nutricional e consumo energético habitual (CEH). Utilizou-se os testes qui-quadrado, exato de Fisher, Mann-Whitney e análise de regressão de Cox univariada e múltipla, com nível de significância de 5%. RESULTADOS: Verificou-se 21,01% de desnutridos pela ASG; 34,78% com risco nutricional pelo NRS e 11,59% com baixo peso pelo índice de massa corporal (IMC). Não houve diferença estatisticamente signi­ficante da prevalência de desnutrição pela ASG (P=0,3344) e de risco nutricional pelo NRS (P=0,2286), entre os tipos de doenças. Os pacientes com risco nutricional apresentaram maior mediana de idade (64,5 vs 58,0 anos; P=0,0246) e menores valores medianos no CEH (1362,1 kcal vs 1525 kcal, P=0,0030); na circunferência de panturrilha (CP) (32,0 cm vs 33,5 cm, P=0,0405); na contagem de linfócitos (CL) (1176,5 cel/mm3 vs 1760,5 cel/mm3, P=0,0095); e maior percentual de baixo peso pelo IMC (22,9% vs 5,6%; P=0,0096). A CL foi associada ao risco nutricional (P=0,0414; HR=1,000; IC95%= 0,999; 1,000). CONCLUSÃO: O NRS foi mais sensível que outros indicadores no diagnóstico de desnutrição. Pacientes com risco apresentaram mais idade e valores menores de CEH, CP, IMC e CL. A baixa CL foi considerada fator associado ao risco nutricional pelo NRS.

Relationship between nutritional status and the clinical outcomes of patients with and without neoplasms according to multiple correspondence analysis / Relação entre estado nutricional e desfechos clínicos pela técnica da análise de correspondência múltipla em pacientes com e sem neoplasias

ABSTRACT BACKGROUND For many years, many studies have reported undesirable outcomes that may occur during the hospital stay of patients diagnosed with malnutrition or even at some nutritional risk. OBJECTIVE To investigate the relationship between nutritional status and clinical outcomes during hospital stay using the multiple correspondence analysis technique. METHODS This cross-sectional study included 600 patients with and without neoplasms. The following data were collected: subjective global assessment, nutritional indicators, nutritional risk screening, anthropometric data (body mass index (BMI), mid-upper arm circumference (MUAC), mid-upper arm muscle circumference (MUAMC), triceps skinfold thickness (TST), recent weight loss (RWL)), and habitual energy intake (HEI/ER <75%). The clinical outcomes of interest were complications, length of hospital stay (LOHS), and death. The data were analyzed by the chi-square or Fisher’s exact test at a significance level of 5%. Multiple correspondence analysis was used for the multivariate data analysis. RESULTS The multiple correspondence analysis map for the patients with neoplasms showed that the following characteristics were associated and represented by death, complications, and a greater likelihood of LOHS ≥7 days: underweight according to BMI; TST, MUAC, and MUAMC ≤15th percentile; malnutrition according to the subjective global assessment; at nutritional risk according to the nutritional risk screening; being male; age ≥60 years; and HEI/ER <75%. The multiple correspondence analysis map for the patients without neoplasms showed that the following characteristics were associated and represented by death: underweight according to BMI; TST ≤15th percentile; malnutrition according to the subjective global assessment; and at nutritional risk according to the nutritional risk screening. Complications and LOHS ≥7 days represented the categories male, no recent weight loss, HEI/ER <75%, MUAC and MUAMC ≤15th percentile, TST between the 15th and 85th percentiles, and age <60 years. CONCLUSION The results of this study confirm an association between unsatisfactory nutritional indicators and undesirable clinical outcomes.

In-hospital weight loss, prescribed diet and food acceptance.

BACKGROUND: Weight loss and malnutrition may be caused by many factors, including type of disease and treatment. AIM: The present study investigated the occurrence of in-hospital weight loss and related factors. METHOD: This cross-sectional study investigated the following variables of 456 hospitalized patients: gender, age, disease, weight variation during hospital stay, and type and acceptance of the prescribed diet. Repeated measures analysis of variance (ANOVA) was used for comparing patients' weight in the first three days in hospital stay and determining which factors affect weight. The generalized estimating equation was used for comparing the food acceptance rates. The significance level was set at 5%. RESULTS: The most prescribed diet was the regular (28.8%) and 45.5% of the patients lost weight during their stay. Acceptance of hospital food increased from the first to the third days of stay (p=0.0022) but weight loss was still significant (p<0.0001). Age and type of prescribed diet did not affect weight loss during the study period but type of disease and gender did. Patients with neoplasms (p=0.0052) and males (p=0.0002) lost more weight. CONCLUSION: Weight loss during hospital stay was associated only with gender and type of disease.

Comparison of nutritional diagnosis methods and prediction of clinical outcomes in patients with neoplasms and digestive tract diseases.

BACKGROUND & AIMS: Nowadays studies are advised to compare nutritional risk assessed by different instruments with clinical outcomes. This study compared nutritional diagnosis methods and identified the best predictor of clinical outcomes. METHODS: This cross-sectional study included 500 hospitalized patients with neoplasms and digestive tract diseases (DTD). Their nutritional status was determined by nutritional risk screening (NRS), subjective global assessment (SGA), and anthropometry, and compared with the clinical outcomes. The Kappa coefficient measured the agreement between the methods. Associations between risk factors and clinical outcomes were investigated by Cox, univariate logistic, and multiple logistic regression analyses at a significance level of 5%. RESULTS: In DTD and cancer patients, SGA and NRS presented good agreement, but agreement of either with anthropometry was poor. According to Cox regression, both SGA and NRS predicted complications in DTD patients. However, none of the instruments was capable of predicting complications in cancer patients or death in DTD patients. In cancer patients, SGA and age were considered risk factors for death. In DTD patients, age, SGA, and NRS predicted a long hospital stay. In cancer patients, long stays were associated with age and SGA. CONCLUSION: SGA and NRS are highly sensitive for predicting complications in DTD patients. Old age and SGA predicted death in cancer patients. Advanced age and SGA also predicted long hospital stays for DTD and cancer patients, but NRS predicted long hospital stays only for DTD patients.

RACIONAL: A perda de peso e a desnutrição podem ser desencadeadas por vários fatores, além de estar relacionada com o tipo de doença e com a terapia empregada. OBJETIVO: Investigar a ocorrência de perda de peso e fatores relacionados, durante a internação. MÉTODO: Estudo transversal com 456 pacientes hospitalizados, sendo estudadas as seguintes variáveis: sexo, idade, doença, evolução de peso, tipo e aceitação da dieta prescrita. Para comparar o peso entre os três primeiros dias de internação e para o estudo dos fatores que interferiram na alteração do peso, foi utilizada a Análise de Variância (ANOVA) para medidas repetidas. Para comparar a proporção de respostas na aceitação da dieta, foi utilizado o método das Equações de Estimação Generalizadas (EEG), com nível de significância de 5%. RESULTADOS: A dieta mais prescrita foi a geral (28.8%) e 45.5% dos pacientes perderam peso durante a internação. A aceitação da dieta hospitalar melhorou do 1º para o 3º dia de internação (p=0.0022), mas mesmo assim, a perda foi significativa (p<0.0001). Verificou-se que a idade e o tipo de dieta prescrita não influenciaram na perda de peso no período; mas, o tipo de doença e o sexo, apresentaram influência nos pacientes portadores de neoplasias (p=0.0052) e o sexo masculino (p=0.0002) apresentou mais perda de peso. CONCLUSÃO: A perda de peso no decorrer da internação foi relacionada apenas ao sexo e ao tipo de doença. .

Determinants of malnutrition and post-operative complications in hospitalized surgical patients.

The study aimed to determine the nutritional status (NS) of hospitalized surgical patients and investigate a possible association between NS and type of disease, type of surgery and post-operative complications. The gender, age, disease, surgery, complications, length of hospital stay, number of medications, laboratory test results, and energy intake of 388 hospitalized surgical patients were recorded. NS was determined by classical anthropometry. The inclusion criteria were: nutritional status assessment done within the first 24 hours of admission, age ≥ 20 years, and complete medical history. Univariate and multiple Cox's regression analyses were employed to determine which variables were possible risk factors of malnutrition and complications. Malnutrition was more common in males (p=0.017), individuals aged 70 to 79 years (p=0.000), and individuals with neoplasms and digestive tract diseases (p=0.000). Malnourished individuals had longer hospital stays (p=0.013) and required more medications (p=0.001). The risk of malnutrition was associated with age and disease. Individuals aged 70 years or more had a two-fold increased risk of malnutrition (p=0.014; RR=2.207; 95% CI 1.169-4.165); those with neoplasms (p=0.008; RR=14.950; 95% CI 2.011-111.151) and those having digestive tract diseases (p=0.009; RR=14.826; 95% CI 1.939-113.362) had a 14-fold increased risk of malnutrition. Complications prevailed in older individuals (p=0.016), individuals with longer hospital stays (p=0.007), and individuals who died (p=0.002). The risk of complications was associated with age and BMI. In the present study, the risk of malnutrition was associated with age and type of disease; old age and low BMI may increase complications.

BACKGROUND: The nutritional status (NS) of patients with neoplasms can affect length of hospital stay. AIM: To investigated nutritional changes and risk factors associated with length of hospital stay in patients with neoplasms. METHODS: A cross-sectional study was done to investigate nutritional status by classic anthropometry, energy intake, gastrointestinal changes, indicators of nutritional risk and length of hospital stay in 93 patients with neoplasms. The risk factors associated with long hospital stays were then determined. RESULTS: Patients with digestive neoplasms presented significantly longer hospital stays. These patients were 26 times more likely to stay at the hospital seven or more days than patients with gynecological neoplasms. Additionally, patients with recent weight loss were 4.5 times more likely to stay seven or more days at the hospital than those without recent weight loss. CONCLUSION: Digestive neoplasms, low body mass index and recent weight loss are risk factors for longer hospital stays.

Investigation of nutritional risk factors using anthropometric indicators in hospitalized surgery patients.

CONTEXT: The investigation of risk factors associated with nutritional status could contribute for better knowledge of the malnutrition. OBJECTIVE: To investigate the incidence of malnutrition and its possible association with many parameters that assess nutritional status and to identify the associated risk factors. METHODS: The nutritional status was assessed in 235 hospitalized patients. Malnutrition was defined as present when the patient presented at least two anthropometric criteria below the normal range and habitual energy intake below 75% of the energy requirement (HEI/ER<75%). Gender, age, type of disease, recent weight change and dental problems were investigated as possible associated risk factors. The chi-square and Mann-Whitney tests were used to compare the data and univariate and multiple logistic regressions were used to identify the factors associated with malnutrition. The odds ratio (OR) and confidence interval (CI) of 95% were calculated with the significance level set at 5% (P<0.05). RESULTS: One-fifth (20%) of the patients were malnourished on admission to the hospital and 27.5% reported recent weight loss. Malnutrition (P<0.0001) was greater in patients with malignant diseases. The only variables significantly associated with malnutrition according to univariate logistic regression were recent weight loss (P = 0.0058; OR = 2.909; IC95% = 1.362; 6.212) and malignant disease (P = 0.0001; OR = 3.847; IC95% = 1.948; 7.597). When multiple regression was used in the model which included type of disease, malignant disease was shown to increase the chance of malnutrition fourfold (P = 0.0002; OR = 3.855; IC95% = 1.914; 7.766). When disease was excluded, recent weight loss also increased malnutrition fourfold (P = 0.0012; OR = 3.716; IC95% = 1.677; 8.236). CONCLUSION: Patients with a history of recent weight loss and those with malignant diseases are more susceptible to malnutrition.

OBJETIVO: Investigar a incidência de risco nutricional com a associação de vários parâmetros de avaliação nutricional e identificar os fatores de risco relacionados. MÉTODO: Foi avaliado o risco nutricional em 235 pacientes hospitalizados com doenças benignas e malignas, sendo o sexo, a faixa etária, o tipo de doença, a alteração de peso recente e os problemas dentários, investigados como possíveis fatores de risco associados. Para a comparação dos dados, foi utilizado o teste Qui ao quadrado e Mann-Whitney e para identificar os fatores associados ao risco nutricional foi utilizada a análise de regressão logística univariada e múltipla, sendo calculado o odds ratio (OR) e o intervalo de confiança (IC) de 95%, com P<0,05. RESULTADOS: Verificou-se 20% dos pacientes com risco nutricional na admissão hospitalar e 27,5% referiram perda de peso recente, com diferença significativa entre os grupos nos parâmetros avaliados e para o risco nutricional de desnutrição (P<0,0001), maior naqueles com doenças malignas. Na regressão logística univariada, as únicas variáveis significativas para o risco nutricional foram a perda de peso recente (P = 0,0058; OR = 2,909; IC95% = 1,362; 6,212) e a doença maligna (P = 0,0001; OR = 3,847; IC95% =1 ,948; 7,597). Posteriormente, na regressão múltipla, no modelo com o tipo de doença, foi comprovado que a doença maligna elevou a chance de risco nutricional em 4 vezes (P = 0,0002; OR = 3,855; IC95% = 1,914; 7,766). Excluindo-se a doença, comprovou-se que a perda de peso recente elevou o risco nutricional também em quase 4 vezes (P = 0,0012; OR = 3,716; IC95% = 1,677; 8,236). CONCLUSÃO: Pacientes que perderam peso recentemente e aqueles com doença maligna apresentaram mais chances de desenvolver risco nutricional.

Clinical and nutritional status of surgical patients with and without malignant diseases: cross-sectional study.

CONTEXT: Malnutrition is frequently observed in inpatients with malignant diseases and may contribute to longer hospital stays. OBJECTIVE: To compare the nutritional status, lymphocyte count, hemoglobin values and length of hospital stay of patients with and without malignant diseases. METHODS: This comparative study assessed indicators of nutritional status, namely body mass index, recent weight loss, lymphocyte count, hemoglobin and length of hospital stay, of 928 surgical patients with and without malignant diseases (50.2% females and 49.8% males). The chi-square test was used to compare proportions and the Mann-Whitney test was used to compare continuous measurements between two groups. The significance level was set at 5%. RESULTS: Patients with malignant diseases had longer hospital stays (P<0.0001), furthermore, a higher percentage of patients with malignant diseases had body mass index <18.5 (P<0.0001) and experienced recent weight changes (P<0.0002). Lymphocyte count also differed statistically between the groups (P = 0.0131), which lower levels were identified among patients with malignant diseases. CONCLUSION: The lymphocyte count, hemoglobin values and weight loss are important findings of nutritional depletion in patients with malignant diseases.

CONTEXTO: A desnutrição em pacientes com doenças malignas é frequentemente observada durante a hospitalização e pode acarretar num aumento do período de internação. OBJETIVO: Comparar o estado nutricional, valores de linfócitos e hemoglobina e o tempo de internação em pacientes com e sem doenças malignas. MÉTODOS: Estudo comparativo com 928 pacientes cirúrgicos com e sem doenças malignas (50,2 por cento do sexo feminino e 49,8 por cento do sexo masculino), sendo analisados os indicadores do estado nutricional como índice de massa corporal, perda de peso recente, contagem de linfócitos, hemoglobina e o tempo de internação. Foi aplicado o teste qui ao quadrado para comparação de proporções e para a comparação de medidas contínuas entre dois grupos e foi aplicado também o teste de Mann-Whitney, com nível de significância de 5 por cento. RESULTADOS: Os pacientes com doenças malignas ficaram internados por mais tempo (P<0.0001), sendo constatado ainda neste grupo, maior percentual de pacientes com índice de massa corporal <18.5 (P<0.0001) e alteração de peso (P = 0.0002). Na contagem de linfócitos, constatou-se diferença estatística entre os grupos (P = 0,0131), sendo os menores valores encontrados entre os pacientes com doenças malignas (P = 0.01). CONCLUSÃO: A contagem de linfócitos, os valores de hemoglobina e a perda ponderal são achados importantes de depleção nutricional em pacientes com doenças malignas.

Nutrition status and risk factors associated with length of hospital stay for surgical patients.

OBJECTIVE: To diagnose the nutrition status of hospitalized patients and identify the risk factors associated with hospital length of stay (LOS). METHODS: The subjective approach and the body mass index (BMI) were used to classify the nutrition status, and other indicators (anthropometry, biochemistry, and energy intake) were analyzed regarding their association with length of hospital stay of 350 patients. The chi-square test was used to compare proportions, and the Mann-Whitney or Kruskal-Wallis test was used to compare continuous measures. Linear association was verified using Spearman's rank correlation coefficient. Cox's regression model was used to investigate factors associated with LOS. RESULTS: Disease was the factor that influenced LOS the most in the studied population. Longer LOS prevailed in males (P < .0001), patients aged ≥60 years (P = .0008), patients with neoplasms (P < .0001), patients who lost weight during their hospital stay (P < .0001), and malnourished patients (P = .0034). There was a negative and significant, but weak, correlation between LOS and nutrition indicators (calf circumference, arm circumference, triceps skinfold thickness, subscapular skinfold thickness, arm fat area, lymphocyte count, and hemoglobin). Among adults, well-nourished patients were 3 times more likely to be discharged sooner (P = .0002, RR = 3.3 [1.7-6.2]) than those who had some degree of malnutrition. Well-nourished patients with digestive tract diseases (DTD) were also discharged sooner than malnourished patients with the same condition (P = .02, RR = 2.5 [1.1-5.8]). In patients with neoplasms, arm circumference was an independent risk factor to assess LOS (P = .009, RR = 1.1 [1.0-1.1]). CONCLUSIONS: LOS was associated with disease and nutrition status. Among the more common diseases, nutrition status according to the subjective approach determined the LOS for patients with DTD and nutrition status according to arm circumference determined the LOS for patients with neoplasms.

Dental and gastrointestinal changes as indicators of nutritional depletion in elderly inpatients.

OBJECTIVE: The objective of this study was to identify the associations between the nutritional status of elderly patients and length of hospital stay and presence of dental and gastrointestinal changes. CASUISTIC AND METHOD: This cross-sectional study analyzed anthropometric and food intake indicators, dental and gastrointestinal changes and length of hospital stay of 441 elderly patients of both genders. The Pearson's correlation coefficient was used to verify the correlation between the nutritional status of the elderly patients and length of hospital stay and presence of dental and gastrointestinal changes. The significance level was set at P < 0.05. RESULTS: Dietary and anthropometric variables as well as length of hospital stay were similar for patients with and without dental changes. Patients with gastrointestinal changes consumed less energy (P < 0.05) than patients without gastrointestinal changes. Length of hospital stay was inversely correlated with body mass index (r = -0.15; P < 0.05); arm circumference was inversely correlated with presence of dental changes (r = -0.12; P < 0.05) and mid-arm muscle circumference was inversely correlated with gastrointestinal changes (r = -0.12; P < 0.05). CONCLUSION: Dental and gastrointestinal changes are important indicators of nutritional depletion and dietary intake of inpatients.

Estudo comparativo de indicadores nutricionais em pacientes com neoplasias do trato digestório / Comparative study of nutritional status indicators among patients with gastrointestinal neoplasms

RACIONAL: O câncer tem sido considerado atualmente como um dos principais problemas de saúde pública em todo o mundo e os tumores mais frequentes são os dos tratos gastrintestinal e o respiratório. OBJETIVO: Comparar indicadores do estado nutricional em pacientes portadores de neoplasias do trato digestório. MÉTODO: Estudo comparativo de indicadores nutricionais (antropométricos, laboratoriais e dietéticos), entre 28 pacientes portadores de neoplasias do trato digestório (esofágicas, gástricas e intestinais), em um hospital universitário. RESULTADOS: Não foi encontrada diferença significativa entre os três grupos de neoplasia para os indicadores laboratoriais, de consumo alimentar e antropométricos, exceto para a circunferência do braço (P=0,0471). A perda de peso ocorrida durante a internação foi observada em 46,4 por cento dos pacientes estudados e a dieta enteral foi a prescrição dietética mais prevalente entre os pacientes, especialmente nos portadores de neoplasia de esôfago. CONCLUSÃO: Pacientes com diagnóstico de neoplasia de trato digestório apresentam comprometimento no estado nutricional e necessitam de acompanhamento nutricional no decorrer do tratamento destas enfermidades.

BACKGROUND: Cancer nowadays is considered one of the biggest health problem all over the world and the digestive and respiratory tumors are the most frequent among them. AIM: To compare nutritional indicators among patients with esophageal, stomach and intestinal neoplasms. METHODS: A comparative study was carried out assessing indicators of nutritional status (anthropometry, biochemistry and diet) of 28 patients with digestive neoplasms. RESULTS: Groups were statistically paired by gender, biochemical tests, food intake and anthropometrics measurements, except for the upper arm circumference (P=0.0471). Weight loss was verified for 46.4 percent of the studied patients and the tube diet was the most prevalent dietary prescription for the patients, especially among those with esophageal neoplasms. CONCLUSION: Patients with esophageal, stomach and intestinal neoplasms have poor nutritional status and need continuous dietary care during the treatment of their diseases.
