Sarcopenia is a syndrome associated with reduced strength, mass and function of skeletal muscles. Aging of gastric cancer patients, lack of nutritional intake, and pathological mechanisms of gastric cancer increase the likelihood of sarcopenia. Sarcopenia is associated with the development of gastric cancer and may be a risk factor for the formation of gastric cancer. Sarcopenia is closely related to the prognosis and treatment of gastric cancer. At present, the treatment of sarcopenia is still in the exploratory stage, and more research is needed to obtain better treatment plans and improve the quality of life of patients. This article reviews the research status of sarcopenia and gastric cancer in order to provide evidence for clinical research.
Objective To compare the clinical effects of early enteral and parenteral nutrition, and to study their effects on cytokine release, cellular immune function and protein metabolism in early postoperative patients with gastrointestinal cancer. Methods Thirty-six patients with gastrointestinal cancer were randomly divided into early postoperative enteral nutrition (EN) group (19 cases) and parenteral nutrition (PN) group (17 cases), and they were supported with EN or PN during postoperative period of 1-7 days, respectively. The levels of serum tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), interleukin-6 (IL-6), and interleukin-10 (IL-10) were measured by ELISA. The total lymphocyte count (TLC) and subgroups of lymphocyte (CD3, CD4, CD8, CD4/CD8 and NK cell) were determined with flow cytometer. The urea and creatinine of the 24 h excretory urine were examined at four different phases: preoperative (pre), 1st d, 3rd d and 5th d after operation (pod). The clinical recovery indicators and the complication incidence were also observed. Results All the patients followed the project of nutritional support and relevant examinations, and there was no severe complication and no patient died during the research. The IL-1β, IL-6 and IL-10, the 24 h urea and creatinine increased, while the serum TNF-α and TLC (except 3, 5 pod of EN group) decreased. There was no marked change of the proportion of lymphocyte subgroups after operation and there was no significant difference of the changes of IL-1β, IL-10 and TNF-α between the two groups as well. The levels of IL-6 (3, 5 pod), the 24 h urea (3, 5 pod) and creatinine (3, 5 pod) were significantly lower in EN group than those in PN group （P＜0.05）, whereas TLC (3, 5 pod) were significantly higher than that in EN group （P＜0.05）. In addition, the postoperative infection incidence （10.5% vs 35.3%）, fever duaration, rehabilitation time and medical cost were significantly lower in EN group than those in PN group （P＜0.05）.Conclusion The early postoperative EN has an advantage over PN in the patients with gastrointestinal cancer, which could decrease the release of cytokine and suppress protein metabolism resulting from operational stress, and could reduce the incidence of postoperative infection and inflammatory reaction time. They could also improve the cellular immune function and decrease the rebilitation duration and medical cost.
Objective To investigate the status of nutrition, nutritional support, and postoperative nutrition-related complications in patients with spinal deformity during orthopedic perioperative period. Methods From February to August 2021, patients who underwent spinal orthopedic surgery for spinal deformity in Peking University Third Hospital were collected. A survey was conducted using self-designed questionnaire, including patient’s general information (gender, age, and type of spinal deformity), nutrition-related information (risks of malnutrition, forms of nutritional support), and postoperative nutrition-related complications. Results A total of 39 patients with spinal deformity were enrolled, and 46.2% (18 cases) were at risk of malnutrition. There were a total of 174 times of nutritional support, and 96.0% (167 times) were parenteral nutrition. The patients’ energy intake from nutritional support accounted for 34.41% of the daily goal energy intake averagely. At admission, one day after operation, and at discharge, the prealbumin was (215.51±34.69), (172.85±31.85), and (163.67±29.15) mg/L, respectively, and the hemoglobin was (138.08±15.67), (119.92±18.01), and (117.69±14.76) g/L, respectively, which were significantly lower one day after operation and at discharge than those at admission (P<0.01). The incidence of postoperative nutrition-related complications during hospitalization was 5.1% (2/39). Conclusions Patients undergoing spinal deformity orthopedics are at high risk of overall malnutrition during the perioperative period, their clinical nutritional interventions are mostly based on parenteral nutrition with a single infusion of nutritional preparations, and the nutritional status is not significantly improved. However, the incidence of postoperative nutrition-related complications is low. Standardized nutrition interventions should be strengthened in the future.
Objective To investigate the clinical efficacy of nutritional support with different proportion of fat on the prognosis of patients with severe community-acquired pneumonia (SCAP). Methods Ninety SCAP patients with nutritional risk treated between January 2014 and July 2015 were randomized into high, normal, and low-proportion fat groups with 30 patients in each. The patients in different groups underwent nutritional support with different fat proportion besides the same medication. Data of albumin, pre-albumin and transferrin were collected and analyzed before treatment and 10 days after treatment. The mortality rates were compared between groups. Results Albumin, pre-albumin and transferrin were similar in all groups before intervention (P>0.05); albumin, pre-albumin and transferrin increased significantly 10 days after treatment in each group (P<0.05). Patients in the normal-fat group acquired significantly more obvious improvements on each index (P<0.05). A shorter length of stay in hospital was observed in the normal-proportion fat group compared with the high and low-proportion fat groups, but there was no significant differences among groups (P>0.05). On the 10th day, the normal -proportion fat proportion group had a significantly higher cure rate and a significantly lower mortality rate than the other two groups (P<0.05). The improvement rate was similar in all groups (P>0.05). Conclusion Supportive treatment with normal fat proportion has a promising value in the improvement of albumin, pre-albumin and transferrin for SCAP patients with a shorter length of stay in hospital, which is worthy of clinical promotion.
Objective To explore the status of nutrition risk and its relative factors in patients of department of gastrointestinal surgery, and to observe the effectiveness of nutrition support on post-operative recovery of patients with gastric cancer. Methods A total of 1 048 cases of in-patients in Department of Gastrointestinal Surgery of Jinan Central Hospital Affiliated Shandong University from January 2015 to January 2016 were collected prospectively, and then screened the nutrition risk of these patients by nutritional risk screening 2002 (NRS-2002) and evaluated the actual malnutrition situation when they left hospital. Then collected 52 gastric cancer patients whose NRS-2002 score ≥3, and divided them to control group and experimental group randomly. The patients of experimental group received extra standard medical nutrition support while the patients of control group did not. Compared the nutritional indexes as well as some postoperative recovery indexes, such as the postoperative exhaust time, postoperative defecation time, infusion stop time, length of hospital stay, and incidence of complications. Results ① Nutritional risk. Among the 1 048 cases, 230 cases (21.9%) had nutritional risk while 118 cases (11.3%) developed to malnutrition. Age and degree of cancer were all related with nutritional risk (P<0.05) while gender was irrelevant (P>0.05). Patients with age ≥60 years, advanced gastric cancer, and colorectal cancer in Ⅲ+Ⅳ staging, had higher rates of nutritional risk than patients with age <60 years, early gastric cancer, and colorectal cancer inⅠ+Ⅱstaging. Results of actual malnutrition was in good accordance with the screening result of NRS-2002 (κ=0.57). ② Influence of nutritional support on gastric cancer patients. Compared with control group, there was an improvement in albumin, pre-albumin, and weight of experimental group and the distinction had statistical significance (P<0.05). The distinction of postoperative exhaust time and incidence of complication between the two groups were not statistically significant (P>0.05), but postoperative defecation time, infusion stop time, and the length of hospital stay of the experimental group were shorter than those of the control group with statistical significance (P<0.05). Conclusions The problem of malnutrition exists generally in the in-patients of department of gastrointestinal surgery. Applying the instrument of nutritional risk assessment to assess the risk as early as possible and giving appropriate nutrition support therapy positively, will make favorable influence to the prognosis of gastric cancer patients.
Objective To observe the effect of parenteral nutrition (PN) on the protein storage and immunofunction in patients with liver cirrhosis. Methods PN regimes consisted of nonprotein calories (NPC) 20-25 kcal/(kg·d) and nitrogen 0.15-0.20 g/(kg·d), the energy ratio of the glucose and fat emulsion was 2∶1. The PN solution was infused by total nutrition admixture (TNA), 12-16 hours per day for 7 days in 21 liver cirrhosis patients. Perior to the surgery and at 1st, 4th, 7th postoperative day, serum pre-Alb, transferrin (TSF), immunofunction (IgG, IgA, IgM, IgE, CH50, C3, C4, CD3, CD4, CD8, NKC), and nitrogen balance were tested. Results Serum pre-Alb, TSF, nitrogen balance and IgG, IgE, CH50, CD3, CD4, NKC were significantly decreased (Ｐ＜0.05), but the foregoing indices were higher than those of postoperative 1, 4d as compared with postoperative 7d. Conclusion These results bly indicated that postoperative nutritional support is safe and useful, and improve the patient’s nutritional status and immunofunction.
