Nutritional status assessed by Patient-Generated Subjective Global Assessment is associated with toxicity to chemoradiotherapy in women with cervical cancer: a prospective study.

BACKGROUND: Patient-generated subjective global assessment (PG-SGA), a validated tool for nutritional assessment, has been associated with worse clinical outcomes in patients with cancer. However, studies assessing its relationship in chemoradiotherapy outcomes are scarce. The study aimed to determine the prevalence of malnutrition according to PG-SGA and its association with the incidence of toxicity to chemoradiotherapy treatment in women with cervical cancer. METHODS: In a single-centre prospective observational study, we enrolled 391 women with locally advanced cervical cancer. Patients were assessed on the day of their first chemotherapy infusion, when nutritional status was evaluated by the PG-SGA form and anthropometric measurements. Sociodemographic and clinical data were also collected. Toxicity to chemoradiotherapy was assessed weekly and toxicity-induced modification of treatment (TIMT) was defined as any serious adverse event that resulted in treatment delay, interruption, or dose reduction. Multivariate mixed-effects Poisson and Logistic regression models were performed to identify the factors contributing to the outcome number of adverse events ≥ grade 3 and TIMT, respectively. RESULTS: Malnutrition was found in 47.6% of the population. Roughly 1/3 had TIMT and 54.2% experienced at least one symptom ≥grade 3. In the adjusted models, PG-SGA B and C, as well as the score ≥9 were independent predictors of the number of toxicity events ≥grade 3 and higher incidence of TIMT. CONCLUSIONS: PG-SGA may represent an important assessment tool to predict toxicity outcomes in women with cervical cancer, besides being considered a simple, fast, and low-cost tool, which allows early nutritional care.

Cintura Hipertrigliceridêmica em Pacientes Hipertensos / Hypertriglyceridemic Waist in Hypertensive Patients

Fundamentos: O uso de diferentes critérios para a determinação da cintura hipertrigliceridêmica (CHT) pode resultar em interpretações imprecisas, podendo comprometer o diagnóstico de pacientes com risco de desenvolver doenças cardiovasculares. Objetivo: Avaliar a concordância no diagnóstico da CHT utilizando diferentes pontos de corte para classificação da circunferência da cintura, em pacientes hipertensos. Métodos: Trata-se de um estudo transversal realizado com 120 pacientes, de 30 a 74 anos de idade, de ambos os sexos em atendimento ambulatorial. Realizou-se avaliação antropométrica (peso, altura e circunferência da cintura) e dos níveis séricos de triglicérides. A CHT foi definida pela presença simultânea da circunferência da cintura aumentada e hipertrigliceridemia. A concordância entre os diagnósticos de cintura hipertrigliceridêmica foi avaliada pelo índice Kappa. Resultados: A prevalência da CHT foi maior em adultos, para ambos os sexos pelos critérios do International Diabetes Federation (IDF) e Organização Mundial de Saúde (OMS) (28%), já pelo National Cholesterol Education Program - Adult Treatment Panel III (NCEP-ATP III) foram identificados 22,7% de indivíduos. Identificou-se uma concordância quase perfeita (0,864) entre o diagnóstico da CHT pelos pontos de corte da IDF versus NCEP-ATP III, OMS versus NCEP-ATP III. Entre o IDF e OMS a concordância foi perfeita. Conclusão: A utilização dos pontos de corte da circunferência da cintura propostos pelo IDF e OMS, para caracterizar indivíduos com cintura hipertrigliceridêmica foi melhor do que a do NCEP-ATP III

Background: The adoption of different criteria to determine the occurrence of the hypertriglyceridemic waist (HTW) can result in inaccurate interpretations, compromising the diagnosis of patients at risk of developing cardiovascular diseases. Objective: To evaluate the diagnostic agreement of HTW using different cut-off points for waist circumference in hypertensive patients. Methods: Cross-sectional study including 120 patients of both sexes, aged 30 to 74 years and receiving care on an outpatient basis. We assessed the participants' anthropometric data (weight, height, and waist circumference) and determined their serum triglycerides levels. The diagnosis of HTW was defined by concurrent increased waist circumference and hypertriglyceridemia. The agreement among the diagnoses of HTW was assessed with the kappa index. Results: In adults of both sexes, the HTW had a higher prevalence (28%) when determined by the criteria defined by the International Diabetes Federation (IDF) and the World Health Organization (WHO) than by those defined by the National Cholesterol Education Program - Adult Treatment Panel III (NCEP-ATP III, 22.7%). We identified an almost perfect agreement (0.864) between the diagnosis of HTW determined by the cut-off points of the IDF versus NCEP-ATP III and by the WHO versus NCEP-ATP III. The correlation was perfect between the diagnoses established by the IDF and WHO. Conclusion: The cut-off points for waist circumference proposed by the IDF and WHO was better than those by the NCEP-ATP III to characterize individuals with HTW
