RESUMEN
BACKGROUND AND OBJECTIVES: To evaluate the effect of oral nutritional supplementation (ONS) on the postdischarge nutritional status and quality of life (QoL) of gastrointestinal cancer patients after surgery. METHODS AND STUDY DESIGN: A multi-center study was conducted on gastrointestinal cancer patients who received surgical treatment from 2013-2015. All patients were screened using the Nutrition Risk Screening 2002 (NRS 2002) to assess nutritional risk. Patients with nutritional risk were randomized into two groups: patients in the study group (n=55) were given dietary guidance and ONS, control group (n=59) received only dietary guidance. Anthropometric measurements, nutrition-related laboratory tests, and gastrointestinal function scores were also collected and analyzed using Student's t test and analysis of variance (ANOVA). In addition, the EQ-5D was used to evaluate patients' QoL. RESULTS: Compared with baseline measurements, the body weight of patients in the study group increased by 1.35±0.53 kg and 1.35±0.73 kg at 60 and 90 days, which were significantly higher than those in the control group (-1.01±0.54 kg, and -1.60±0.81 kg at 60 and 90 days). The results from ANOVA showed that only weight and BMI differed significantly between the study and control groups and also between different measurement times (p<0.01). No differences were found for the other indicators or QoL between the study groups. CONCLUSIONS: ONS may improve the weight and BMI of surgically treated gastrointestinal cancer patients postdischarge. However, these effects had little impact on patients' QoL.

BACKGROUND: The development of sensitive myocardial-specific cardiac biomarkers allows for detection of very small amounts of myocardial injury or necrosis. Myocardial injury (MI) as a prelude of the serious perioperative complication myocardial infarction, should be paid more attention, especially in elderly susceptible patients. Myocardial injury after abdominal surgery in elderly patients has not been described yet. The objectives of this study were to identify the incidence, predictors, characteristics and the impact of MI on outcome in elderly patients underwent abdominal surgery. METHODS: Patients aged ≥ 65 who underwent abdominal surgery longer than 2 h between January 2016 and March 2017 were reviewed. Patients with peak troponin I level of 0.04 ng/ml or greater (abnormal laboratory threshold) within once-administration-period and without non-ischemia troponin elevation proof (e.g., sepsis) were assessed for characteristics and prognosis. Risk factors of MI were determined by multivariable regression. RESULTS: Among 285 patients with whole information, 36 patients (12.6%) suffered MI, only 2 patients (0.7%) fulfilled definition of myocardial infarction. With most of them occurred within first 7 days after surgery. Multivariable analysis showed that coronary artery disease (CAD) history [odds ratio (OR) 2.817, P = 0.015], non-laparoscopic surgery (OR 5.181, P = 0.030), blood loss ≥ 800 ml (OR 3.430, P = 0.008), non-venous maintain (OR 2.105, P = 0.047), and infection (OR 4.887, P = 0.008) as risk factors for MI. MI was associated with longer hospital stay (P = 0.006), more cardiac consultation (P = 0.011), higher infection(P = 0.016) and reoperation(P = 0.026) rate. CONCLUSION: MI is common in elderly patients who underwent abdominal surgery, while myocardial infarction is infrequent. They are both associated with risk factors and worse prognosis. MI deserves more attention especially in elderly patients. Troponin I measurement is a useful test after massive surgery, which can help risk-stratifying patients, effective preventing, prompt managing and predicting outcomes. Routine monitoring of cardiac biomarkers especially within 7 days after abdominal surgery in elderly patients is recommended.

BACKGROUND: Polyunsaturated omega-3 fatty acids may beneficially influence healing processes and patient outcomes. The aim of this research was to study the clinical efficacy of fish oil enriched total parenteral nutrition in elderly patients after colorectal cancer surgery. METHODS: Fifty-seven elderly patients with colorectal cancer were enrolled in this prospective, randomized, double-blind, controlled clinical trial. All patients received isocaloric and isonitrogenous total parenteral nutrition by continuous infusion (20 - 24 hours per day) for seven days after surgery. The control group (n = 28) received 1.2 g/kg soybean oil per day, whereas the treatment group (n = 29) received 0.2 g/kg fish oil and 1.0 g/kg soybean oil per day. Blood samples were taken pre-operatively, and at days one and eight after the operation. The plasma levels of CD4, CD8, CD4/CD8, interleukin 6 (IL-6) and tumor necrosis factor α (TNF-α) were measured. Clinical outcomes were then analysed. RESULTS: Patient characteristics were comparable between the two groups. At day eight post-surgery, IL-6, TNF-α and CD8 titres were lower in the treatment group when compared to the control group; these results reached statistical significance. In the treatment group, there were fewer infectious complications and incidences of systemic inflammatory response syndrome (SIRS), and shorter lengths of hospital stay were observed. The total cost of medical care was comparable for the two groups. No serious adverse events occurred in either group. CONCLUSIONS: Fish oil 0.2 g/kg per day administrated to elderly patients after colorectal surgery was safe and may shorten the length of hospital stay and improve clinical outcomes.
