Objective To evaluate the effect of centralized procurement of artificial joint consumables on total arthro-plasty placement surgery.Methods Through a retrospective study,t-test was conducted on the medical quality and effi-ciency,hospitalization cost per time structure through July-December,2021 to July-December,2022 centralized pro-curement of joint replacement surgery in a tertiary hospital in Shanghai.Results After centralized procurement,the amount of knee arthroplasty surgery decreased,and the time of hip replacement surgery was increased,and the difference was statistically significant(P＜0.05).The total cost,cost of consumables,arthrotomy fee of the two types of arthroplasty surgery were significantly decreased,and the difference was statistically significant(P＜0.05).In addition,the average cost of other consumables hospitalization of knee joint surgery patient increased,and the difference was statistically significant(P＜0.05).Conclusion After centralized procurement of artificial joint consumables,the cost of total knee arthroplasty and total hip arthroplasty has decreased significantly,and the quality and efficiency of medical care have not changed significantly.At the same time,hospital managers should pay more attention to the rational use of consumables after centralized procurement.In addition,it calls for increasing the price of surgery to reflect the value of physician services.

Elderly inpatients with coronavirus disease 2019 (COVID-19) are often at nutritional risk and at higher risk of critical disease. The standardized nutrition treatment could effectively improve the nutritional status, quality of life, and clinical outcomes of COVID-19 patients, and is an important component of the comprehensive management of COVID-19. The individualized nutrition diagnosis, treatment and monitoring should be conducted in compliance to standard procedures of medical nutrition therapy, with consideration of the clinical characteristics of elderly COVID-19 inpatients. The Department of Clinical Nutrition at Peking Union Medical College Hospital has integrated the latest clinical nutrition guidelines and clinical practice of nutrition support of COVID-19, with the aim to provide evidence-based, concise and practical recommendations on nutritional management for elderly inpatients with COVID-19. The recommendations here are to inform effective and standardized nutrition support practice.

Patients with cancer are often at nutritional risk and the standardized oral nutritional supplements (ONS) is the preferred treatment for those with gastro-enteral function maintained. ONS could increase the nutrition intake, prevent weight loss, improve the tolerance to anti-cancer treatment, and effectively improve the nutritional status, quality of life and clinical outcomes of cancer patients. The choice of ONS may depend on the type, anatomical location and treatment of cancer. To effectively implement standardized oral nutritional support for patients with cancer, the Nutrition Oncology Branch of Chinese Nutrition Society developed evidence-based, concise and practical recommendations based on the latest clinical nutrition guidelines and research evidence. The purpose is to inform clinical practice and benefit patients with cancer.

Intermittent fasting (IF) is a common intensive nutrition and lifestyle intervention strategy for overweight and obesity. Common regimens in clinical studies consist of time-restricted feeding, alternate-day fasting and 5:2 diet. The mechanisms of IF in weight loss and metabolic health are complex. IF with rational design and regular follow-up has been shown to achieve weight reduction and improve insulin resistance and metabolic health in the population with overweight and obesity. IF has been widely used in many long-term follow-up and large sample studies without major complications. The lean body mass also showed a decrease following weight loss achieved through intermittent fasting intervention, but the ratio of lean body mass to body weight increased when adjusted for changes in weight. This review looks at the progress of clinical researches on common intermittent fasting regimens, in the aim to inform clinical practice.
