ObjectiveTo summarize the research progress of the pathogenesis, diagnosis and treatment of sarcopenia in liver cirrhosis. MethodThe relevant literatures on studies of the pathogenesis, diagnosis and treatment of sarcopenia in liver cirrhosis in recent years were searched and reviewed. ResultsThe sarcopenia was a major complication that could not be ignored in patients with liver cirrhosis, and was closely related to the patient’s quality of life and prognosis. Various mechanisms such as metabolic abnormalities, malnutrition, myostatin, hyperammonemia, hormonal regulation of muscle homeostasis, ubiquitin-proteasome system and autophagy, physical activity, and dysbiosis of the intestinal flora were involved in the development of sarcopenia. There were various diagnostic methods for sarcopenia, but a unified gold standard was still lacking. In addition, some progress had been made in the treatment of sarcopenia in recent years. ConclusionsAlthough current studies obtains preliminary results about relation between liver cirrhosis and sarcopenia, there still exists many problems to be solved. Further research in future will benefit diagnosis and treatment of patients with sarcopenia in liver cirrhosis.
Objective To investigate the nutritional status of hospitalized patients with chronic kidney disease (CKD), analyze the influencing factors, and construct a predictive model to provide a localized theoretical basis and more convenient risk prediction indicators and models for clinical nutrition support and intervention treatment of CKD patients in China. Methods Convenience sampling was used to select hospitalized CKD patients from Department of Nephrology, West China Hospital, Sichuan University, from January to October 2019. General information questionnaires, the Nutritional Risk Screening 2002 scale, and the Huaxi Emotional-distress Index questionnaire were used for data collection. Single factor analyses and multiple logistic regression analysis were conducted to explore the risk factors for malnutrition in CKD hospitalized patients. A predictive model was established and evaluated using receiver operating characteristic (ROC) curve analysis and bootstrap resampling. Results A total of 1059 valid copies of questionnaires were collected out of 1118 distributed. Among the 1059 CKD hospitalized patients, 207 cases (19.5%) were identified as having nutritional risk. The multiple logistic regression analysis showed that CKD stage [odds ratio (OR)=1.874, 95% confidence interval (CI) (1.631, 2.152), P<0.001], age [OR=1.015, 95%CI (1.003, 1.028), P=0.018], and the Huaxi Emotional-distress Index [OR=1.024, 95%CI (1.002, 1.048), P=0.033] were independent risk factors for malnutrition in CKD hospitalized patients, while serum albumin [OR=0.880, 95%CI (0.854, 0.907), P<0.001] was an independent protective factor. The evaluation of the multiple logistic regression analysis predictive model showed a concordance index of 0.977, standard deviation of 0.021, and P<0.05. The area under the ROC curve was 0.977. Conclusions The prevalence of malnutrition is relatively high among CKD hospitalized patients. CKD stage, age, psychological status, and serum albumin are influencing factors for malnutrition in CKD hospitalized patients. The multiple logistic regression model based on the above indicators demonstrates good predictive performance and is expected to provide assistance for early nutritional intervention to improve the clinical outcomes and quality of life for CKD patients with malnutrition in China.
Objective To assess the prevalence of malnutrition in patients with advanced non-small cell lung cancer (NSCLC) using the Global Leadership Initiative on Malnutrition (GLIM) criteria, analyze its associated factors, and explore the adverse effects of malnutrition on advanced NSCLC patients in multiple aspects. Methods Patients with NSCLC who were hospitalized for the first time in the Department of Oncology, Shangjin Hospital, West China Hospital, Sichuan University between January and December 2021 were retrospectively selected as the study objects. Malnutrition assessment was carried out in all patients according to GLIM criteria, and the current situation and related factors of malnutrition were analyzed. The Barthel index scale was used to compare the daily activity ability between the malnourished group and the non-malnourished group, the Quality-of-Life Questionnaire-Core 30 scale was used to compare the quality of life between the two groups, and the adverse reactions of the two groups were compared by the hospital information system course records. Results According to GLIM diagnostic criteria, 134 of 285 patients (47.0%) were diagnosed with malnutrition. The results of binary multiple logistic regression analysis showed that age [60-69 vs. <60 years old: odds ratio (OR)=2.323, 95% confidence interval (CI) (1.277, 4.397); ≥70 vs. <60 years old: OR=10.816, 95%CI (4.185, 27.959)], previous medical history [OR=2.740, 95%CI (1.313, 5.717)], and albumin level [OR=0.905, 95%CI (0.848, 0.965)] were associated with malnutrition in patients with advanced NSCLC (P<0.05). The daily activity ability and quality of life in the malnourished group were significantly worse than those in the non-malnourished group (87.57±12.48 vs. 91.82±6.77, P<0.05; 76.22±11.52 vs. 83.96±9.75, P<0.05), and the incidence of adverse reactions in the malnourished group was higher than that of the non-malnourished group (50.7% vs. 31.8%, P<0.05). Conclusions The prevalence of malnutrition in patients with advanced NSCLC is high, and advanced age, previous medical history and albumin are related factors of malnutrition in patients with advanced NSCLC. Combined malnutrition may have adverse effects on mobility, quality of life and adverse effects of anti-tumor therapy in advanced NSCLC patients.
ObjectiveTo explore the diagnostic efficacy of Geriatric Nutritional Risk Index (GNRI) in malnutrition of elderly patients with chronic obstructive pulmonary disease (COPD) in outpatient department. MethodsOne hundred and five elderly outpatients with COPD were enrolled in the study, and their nutritional screening was carried out. The clinical and laboratory parameters of patients in the normal nutrition group (high GNRI group) and malnutrition group (low GNRI group) were compared, and the correlation analysis was conducted. The diagnostic efficacy of GNRI was evaluated based on the malnutrition universal screening tool (MUST). ResultsThe prevalence of malnutrition was high in COPD elderly outpatients. The prevalence of malnutrition in group D was 61.8%. There were significant differences between the two groups in body mass index, serum albumin, FEV1 percentage in the predicted value, 6-minute walk distance, and the number of acute exacerbations in the past year. GNRI was significantly related to the above parameters. The sensitivity, specificity and accuracy of GNRI were 81.8%, 83.6% and 82.9%, using MUST as the standard. ConclusionGNRI can be used for nutritional screening of COPD patients in elderly outpatients, which is simple, convenient and relatively accurate, and can be popularized in other medical institutions.
Objective To investigate and analyze the incidence and clinical characteristics of malnutrition in patients with tuberculosis and type 2 diabetes. Methods four hundred patients with tuberculosis and type 2 diabetes were diagnosed in the tuberculosis Department of West China Hospital of Sichuan University from June 1, 2018 to April 30, 2023. The incidence and clinical characteristics of malnutrition were analyzed using the nutritional risk Screening 2002 score and the Global Malnutrition Leadership Initiative criteria. Results 170 patients (42.5%) were malnourished. In malnourished patients, 78 cases (45.9%) had fever, 132 cases (77.6%) had cough, 44 cases (25.9%) had hemoptysis, and 36 cases (21.2%) had night sweating. Compared with the non-malnourished patients, the difference was statistically significant (P<0.05). Lymphocyte count was (1.0±0.5)×109/L, albumin was (31.4±20.5)g/L; CD3 count 792.7±205.0, CD4 count 535.4±15.0, CD8 count 429.5±123.0, CD3%: 65.5%±11.1%, CD4%: 39.1%±9.6%, CD8%: 19.1%±9.6%, CD4/CD8: 1.3±0.2, which were significantly lower than those in the group without malnutrition. Pulmonary cavity occurred in 44 cases (25.9%), lesions in 2 - 4 lung fields in 76 cases (44.7%) and lesions in ≥5 lung fields in 52 cases (30.6%), all of which were significantly higher than those in the non-malnutrition group. The above differences were statistically significant.Conclusion We should pay more attention to the screening of malnutrition in patients with tuberculosis and type 2 diabetes. Patients with malnutrition have more obvious clinical symptoms, lower immunity, and more serious imaging lesions.
