Aim: To evaluate the nutritional risk of patients with gastric carcinoma using the methodologies of European Nutritional Risk Screening 2002 (NRS 2002) and its relationship with postoperative results.
Methods: We prospectively evaluated the nutritional risk of 314 cases of gastric carcinoma patients in one center from 2004 to 2007 with NRS 2002, in accordance with China's normal body mass index (BMI), and observed its relationship with postoperative complications, mortality and length of hospital stay.
Results: Of 337 cases, 314 (93.1%) were suitable for assessment by NRS 2002.The number of patients with a score > or = 3 was 125 before operation, comprising 39.8% of patients with gastric carcinoma. The rate of complications (26.2%) of the preoperative nutritional risk group (NRS 2002 score > or = 3) was higher than those in the preoperative nutritional normal group (NRS 2002 score < 3) (P < 0.05). Assessed by multivariate logistics regression analysis, the odds ratio of developing complications was 2.366 (P < 0.05) and 2.277 (P < 0.05) by NRS 2002 score and clinicopathological stage, respectively. The correlation between length of hospital stay and nutritional risk was also assessed by Pearson correlation analysis. The Pearson coefficient was 0.177 (P = 0.002).
Conclusion: Preoperative nutrition score (NRS 2002) > or = 3 predicted more postoperative complications and longer length of hospital stay. It indicated that preoperative nutritional support was necessary in patients with a preoperative nutritional score (NRS 2002) > or = 3.

Objective: Colorectal cancer (CRC) is a common cancer, with chemotherapy as its major therapy. Nutritional status (NS) and adipokines implicated in CRC. We explored the impacts of NS indicators (hemoglobin, albumin, and prealbumin) and serum adipokine (visfatin, adiponectin, and resistin) level on chemotherapy efficacy in late-stage CRC patients.

Objective: The mortality risk for critically ill patients in the intensive care unit (ICU) can be predicted through clinical assessments and laboratory test results. The accurate utilization of these parameters is essential for timely intervention and the initiation of appropriate therapeutic strategies. This study aims to retrospectively examine the relationship between patients' clinical status at ICU admission, prognostic risk scoring systems, biochemical and hematological parameters, and mortality outcomes.

To demonstrate the prevalence of malnutrition risk in a specific rehabilitation setting. The secondary aim of the study was to compare Malnutrition Screening Tool (MST) and Malnutrition Universal Screening Tool (MUST) with Nutritional Risk Screening-2002 (NRS-2002). Patients diagnosed with stroke, anoxic brain injury, spinal cord injury, multiple sclerosis, arthritis, neuromuscular diseases, Parkinson's disease, and lymphedema who were admitted to a rehabilitation hospital were included.

Background: Many nutrition risk screening tools include low body mass index (BMI). It remains uncertain whether it affects the validity of these tools in patients with overweight or obesity. We aimed to determine the frequency of malnutrition risk and evaluate its association with hospital length of stay in hospitalized adults according to BMI classification.

Background: Although malnutrition is associated with poor prognosis in Pulmonary Tuberculosis (PTB) patients, no nutrition-based prediction model has been established for PTB. Herein, we explored the clinical utility of common nutrition scores in predicting the prognosis of PTB patients.
Methods: We retrospectively collected clinical baseline data from 167 patients with secondary PTB who had not previously received anti-TB treatment.
