Background and aim Malnutrition is common in patients with cancer, and its early diagnosis can reduce or prevent further complications and improve the clinical and nutritional prognosis. Adductor Pollicis Muscle Thickness (APMT) and Handgrip Strength have been explored in this population to identify a reduction in strength and muscle mass prior to the use of conventional methods. We aimed to correlate APMT and Handgrip Strength with conventional anthropometric variables in cancer patients and verify their association with nutritional status as determined by the Patient-Generated Subjective Global Assessment (PG-SGA). Methods A cross-sectional study was conducted with 80 patients diagnosed with cancer who were candidates for surgery. Nutritional status was obtained from the PG-SGA. Conventional anthropometric measurements were taken, as well as APMT and Handgrip Strength. Pearson’s correlation analysis and multivariate linear regression were applied to detect the influence of variables on APMT and HGS. A significance level of 5.0% was considered. Results A high prevalence of malnutrition and the need for dietotherapic intervention was found, identified by the PG-SGA. Correlations between APMT and Handgrip Strength with anthropometric variables and with the PG-SGA score were observed. After regression adjustments, the variables that interacted with APMT were TSF and AC, and the PG-SGA score, corrected Muscle Arm Area (CAMA), and age interacted with Handgrip Strength. Conclusion Correlations between anthropometric measurements and the PG-SGA score with APMT and Handgrip Strength were observed, even after adjusting for age and sex. These associations demonstrate that APMT and Handgrip Strength can be used with criterion in patients with cancer as complementary methods to evaluate nutritional risk and the need for nutritional intervention.
Background and aim Nutrition impact symptoms (NIS) are common in cancer patients and the negative impacts on nutritional status indicate the need for research, diagnosis and nutritional intervention in order to reduce the risk of malnutrition. We aimed to verify the presence of malnutrition, the need for nutritional intervention, NIS and their influence on the nutritional status of surgical patients with cancer. Methods This cross-sectional study was carried out in a public tertiary hospital, from March 2017 to October 2019. Nutritional status, the need for nutritional intervention and NIS were assessed through the Patient-Generated Subjective Global Assessment (PG-SGA) in the first 48 hours of hospital admission. Results Among the 135 patients evaluated, 55.6% were elderly and 51.1% were male; patients had a median age of 62 years and a predominance of cancer located in the lower gastrointestinal tract (35.6%). Malnutrition and the need for nutritional intervention were identified in 60.0% and 90.4% of cases, respectively. The presence of three or more NIS was reported by 51.9% of patients. Significant differences in NIS were observed according to sex, PG-SGA classification and PG-SGA score. After logistic regression analysis, it was determined that the symptoms that increased the chances of malnutrition were anorexia, constipation, strange taste, mouth sores and others (depression, dental or financial problems). Conclusion Malnutrition, the need for nutritional intervention and the presence of three or more NIS were elevated in the patients evaluated. Malnutrition was associated with the presence of NIS, indicating the need for attention and care in antineoplastic treatment.
Objective To evaluate the correlation between thickness of the muscle adductor pollicis and anthropometric measurements, body mass index and Subjective Global Assessment in the nutritional assessment of surgical patients.Methods The study population comprised patients admitted to the general and reconstructive surgery unit of a university hospital in the city of Vitória (ES), Brazil. The inclusion criteria were patients evaluated in the first 48 hours of admission, aged ≥20 years, hemodynamically stable, with no edema or ascites. Data analysis was performed using the software Statistical Package for Social Science 21.0, significance level of 5%.Results The sample consisted of 150 patients that were candidates to surgery, mean age of 42.7±12.0 years. The most common reasons for hospitalization were surgical procedures, gastrintestinal diseases and neoplasm. Significant association was observed between thickness of adductor pollicis muscle and Subjective Global Assessment (p=0.021) and body mass index (p=0.008) for nutritional risk. Significant correlation was found between thickness of adductor pollicis muscle and arm muscle circumference, corrected arm muscle area, calf circumference and body mass index. There were no significant correlations between thickness of adductor pollicis muscle and triceps skinfold and age.Conclusion The use of thickness of adductor pollicis muscle proved to be an efficient method to detect malnutrition in surgical patients and it should be added to the screening process of hospitalized patients, since it is easy to perform, inexpensive and noninvasive.
Background Dynapenia is defined as an age-related loss of muscle strength. There is little information on dynapenia in cancer patients and on how it relates to anthropometric variables. The aim of this study was to analyze the presence of dynapenia and its association with anthropometric variables in hospitalized cancer patients. Methods Participants comprised adult and elderly cancer patients evaluated within the first 48 h of hospital admission to a tertiary public hospital, a referral center for gastrointestinal tract surgery. Anthropometric variables were measured according to standardized protocols. Dynapenia was identified based on handgrip strength (HGS), according to the cutoff points defined by the European Working Group on Sarcopenia in Older People (EWGSOP2), with values for women < 16 kg and for men < 27 kg. Statistical analysis was performed using SPSS software, version 22.0, with a significance level of 5%. Results This study included 158 patients aged in average 59.5 ± 14.0 years; of these, 53.6% were elderly, 58.9% non-white and 59.5% had some degree of malnutrition. The most prevalent type of cancer was that of the lower gastrointestinal tract (33.5%). The presence of dynapenia was observed in 23.4% of the patients and cachexia in 36.1%. There was an association between dynapenia with age (p < 0.001), life stage (p = 0.002) and race/color (p = 0.027), and also with body mass index (BMI) (p = 0.001) and adductor pollicis muscle thickness (APMT) of both hands (p < 0.05). After logistic regression analysis, adjusted for the sociodemographic variables, the APMT of the dominant hand and the low weight determined by body mass index remained associated with the occurrence of dynapenia (p < 0.05). Conclusions In this study we confirmed that dynapenia was present in cancer patients, being associated with APMT of the dominant hand and low weight. HSG was proven to be a reliable and complementary measure to be added to the process of assessing nutritional status, contributing to the nutritional diagnosis of these patients and to the detection of early muscle depletion.
Resumo Objetivo Rastrear o risco de sarcopenia em indivíduos hospitalizados por meio dos instrumentos SARC-F e SARC-Calf e verificar a associação entre o risco de sarcopenia com as variáveis sociodemográficas, clínicas e as variáveis que compõem o fenótipo de sarcopenia. Métodos Trata-se de um estudo transversal. Características sociodemográficas, clínicas e todas as variáveis que compõem o fenótipo de sarcopenia (força de prensão palmar, massa muscular e velocidade de marcha) foram investigadas. Para o rastreamento e diagnóstico da sarcopenia adotou-se o algoritmo e critérios propostos pelo European Working Group on Sarcopenia in Older People (EWGSOP2). Resultados Participaram 90 indivíduos. A maioria encontrava-se sem sinais sugestivos de sarcopenia, tanto pelo SARC-F (58,9%) quanto pelo SARC-Calf (68,9%), com força de preensão palmar (FPP) (28,59±9,21;26,74±10,60) e índice de massa muscular esquelética apendicular (IMMEA) (9,31±1,78;9,58±1,62) normais e com baixa velocidade de marcha (VM) (0,69±0,26; 0,68±0,44), respectivamente. O SARC-F apresentou associação significativa com as variáveis sexo (p=0,032), FPP (p<0,001), VM (p=0,001) e sarcopenia (p<0,001). Quando da adição da circunferência da panturrilha (CP), foi encontrado associação com as variáveis grupo etário (p=0,029), atividade laboral (p=0,008), FPP (p<0,001), IMMEA (p=0,033), VM (p=0,019) e sarcopenia (p<0,001). Conclusão O risco de sarcopenia foi observado em aproximadamente um terço dos pacientes avaliados. Sugere-se o uso rotineiro nos hospitais da ferramenta de rastreamento de sarcopenia SARC-Calf, uma vez que apresentou associação com os três fatores preditivos da sarcopenia, além de ser um instrumento de aplicação ágil, baixo custo e não invasivo. A investigação do diagnóstico da sarcopenia deve ser encorajada na prática clínica.
