ABSTRACT
ABSTRACT Objective To verify whether the presence of related nutritional risk indicators prior to COVID-19 diagnosis is associated with poor survival in patients with cancer. Methods We retrospectively analyzed the data of hospitalized cancer patients who tested positive for COVID-19 between March 2020 and February 2021. Nutritional risk was defined as the presence of one of the following characteristics: body mass index <20kg/m 2 , scored Patient-generated Subjective Global Assessment ≥9 points or classification B, albumin level <3.5g/dL, and C-reactive protein level ≥10mg/L, evaluated between 7 and 60 days prior to the date of patient inclusion. The endpoint measure was all-cause mortality within 30 days of COVID-19 diagnosis. Results A total of 253 patients were included, most of whom were elderly (62.4%) and female (63.6%). Overall, 45.4% of the patients were at nutritional risk. Survival was significantly lower in patients at nutritional risk (8 days; interquartile range [IQR]: 3-29) than in patients not at nutritional risk (16 days; IQR: 6-30) (p<0.001). The presence of prior nutritional risk was associated with increased 30-day mortality (HR: 1.42; 95%CI: 1.03-1.94), regardless of age, gender, tumor site or stage, and other risk factors, and the model had good discrimination accuracy (concordance statistic: 0.744). Conclusion The presence of prior nutritional risk indicators is related to poor prognosis in patients with cancer and COVID-19, emphasizing the importance of nutritional care, notably during this pandemic.
ABSTRACT
RACIONAL: Estudos recentes mostram que a abreviação do jejum pré-operatório, ao contrário do jejum de 6-8 h apresenta vários benefícios. Pacientes que recebem carboidratos apresentam menos fome e menos ansiedade do que os que permaneceram em jejum noturno. A ingestão pré-operatória de carboidratos por via oral no dia da operação diminui a resposta orgânica ao trauma. OBJETIVO: Avaliar o efeito da ingestão de bebida com carboidratos 6 e 2 horas antes da operação na ocorrência de sintomas gastrointestinais pós-operatórios em pacientes colecistectomizadas. MÉTODOS: Estudo prospectivo e randomizado com 54 pacientes do sexo feminino (42[19-69] anos) candidatas à colecistectomia eletiva foram randomizadas para receber uma bebida contendo 12.5% de carboidratos, 6 (400 mL) e 2 horas (200 mL) antes da operação (grupo carboidrato n = 28) ou jejum de 6-8 horas (grupo convencional n= 26). As variáveis investigadas foram a ocorrência de vômitos, náuseas, distensão abdominal, eliminação de flatos e fezes, e o tempo de internação no pós-operatório. RESULTADOS: A ocorrência de distensão abdominal (42.3% vs 17.8%; P = 0,04), vômitos (53.8% vs 21.4%; P = 0,01) a associação de dois ou mais sintomas gastrointestinais (73.1% vs 39.3%; P = 0,01) e o tempo de internação pós-operatória (2 [1-3] vs 1 [1-3] dias; P = 0,04) foram significativamente menores no grupo carboidrato. CONCLUSÃO: A ingestão carboidratos no pré-operatório diminui a ocorrência de manifestações gastrointestinais pós-operatórias e o tempo de internação em colecistectomia.
BACKGROUND: Earlier reports have shown that performing operations in fed, opposed to overnight-fasted patients, has several benefits. Preoperative patients receiving carbohydrates were found to be less hungry and less anxious than those receiving placebo or those fasting overnight. Preoperative oral carbohydrate loading on the day of operation may diminish the organic response to trauma. AIM: To investigate the effects of preoperative carbohydrate-rich drinks regarding gastrointestinal symptoms after cholecystectomy. METHODS: Randomized prospective trial. A total of 54 female patients (average age = 42[19-69] years-old) scheduled for elective cholecystectomy were randomized to receive either a beverage containing 12.5% carbohydrate, 6 (400 mL) and 2 hours (200 mL) before surgery (group carbohydrate n=28) or fasting for 6-8 hours (control group n=26). Parameters investigated included the occurrence of vomit, nausea, abdominal distention, passage of flatus and feces, and the length of postoperative hospital stay. RESULTS: Abdominal distension (42.3 vs 17.8%; P = 0,04), episodes of vomiting (53.8% vs 21.4%; P = 0,01), the presence of two or more associated gastrointestinal symptoms (73.1% vs 39.3%; P = 0,01), and the length of postoperative hospital stay (2 [1-3] vs 1 [1-3] days; P = 0,04) was significantly smaller in the carbohydrate control group. CONCLUSION: Preoperative oral carbohydrate administration reduces both postoperative gastrointestinal discomfort and postoperative hospital stay after cholecystectomy.
