Objective:To screen and extract relevant evidence on the management of malnutrition in pediatric cancer patients and provide a best evidence summary.Methods:A systematic search was conducted across multiple websites and databases, including UpToDate, BMJ Best Practice, WHO website, Guidelines International Network, National Institute for Health and Care Excellence, National Guideline Clearinghouse, PubMed, Web of Science Core Collection, Embase, Cochrane Library, China National Knowledge Infrastructure, China Biology Medicine disc, Wanfang Data and others, for evidence on nutritional management of malnutrition in pediatric cancer patients. The search included literature from inception to August 31, 2023. Literature was selected following strict inclusion and exclusion criteria by researchers trained in evidence-based nursing courses. The quality of the selected literature was evaluated, and evidence was extracted and summarized.Results:A total of 11 articles were included, comprising two clinical decision papers, three guidelines, one evidence summary, two systematic reviews, and three expert consensus documents. The evidence was summarized into 24 evidence across five main areas: multidisciplinary team approach, nutritional risk screening and assessment, nutrient intake, dietary and nutritional education, and enteral and parenteral nutrition support.Conclusions:This study provides a best evidence summary for the nutritional management of malnutrition in pediatric cancer patients, offering evidence-based support for clinical practice among healthcare professionals.

Objective: To determine the personal dose level of radiation workers in medical institutions at the municipal level and below in a city, and to provide a scientific support for strengthening the radiation protection in the city’s medical institutions. Methods: Information of the successful applicants for the "Radiation Worker Permit" from 174 medical institutions at the municipal level and below was collected from October 1, 2011 to December 31, 2014. The annual effective dose was calculated based on the personal dose monitoring report, and indicators including sex, permit application time, hospital level, type of occupational radiation, length of radiation work, blood test, and micronucleated lymphocyte rate were analyzed. Results: Of the 1 143 radiation worker permit applications submitted by medical institutions the municipal level and below in this city from 2011 to 2014, 1 123 provided at least one personal dose monitoring report. The annual effective dose of the radiation workers was 0-4.76 mSv (mean 0.31±0.40 mSv) , and the collective annual effective dose was 351.96 mSv. The annual effective dose was significantly different between radiation workers with different times of permit application, hospital levels, and types of occupational radiation (P<0.05) . Interventional radiology workers had the highest annual effective dose (0.63 mSv) , and annual effective dose was significantly different between interventional radiology workers with different lengths of radiation work (H=10.812, P<0.05) . Conclusion The personal radiation dose of radiation workers in medical institutions at the municipal level and below in this city is maintained at a relatively low level, suggesting that the occupational environment is relatively safe for these workers. However, more focus should be placed on clinical interventional radiology workers.

Objective The reactivity of the PICC comprehensive maintenance model and the ward maintenance model was evaluated.The differences between these two models were compared so that the better maintenance model could be chosen for improving the service of the PICC comprehensive maintenance model. Methods Four hundred and fifty patients with the PICC catheter were chosen randomly.Three hundred and forty patients received the PICC comprehensive maintenance model (mainly in the out-patient department and combined with the network maintenance ).One hundred and ten patients received the ward maintenance model (mainly in the in-patient ward).The WHO reactivity questionnaires of health system were provided.The results of the valid questionnaires were calculated and analyzed.Results Four hundred and twenty-nine questionnaires (326 for the comprehensive maintenance model and 1 03 for the ward maintenance model)were collected.The reactivity evaluation of confidentiality,communication,autonomy,timeliness,basic facilities and selective dimension in the comprehensive maintenance model were significantly higher than those in the ward maintenance model (P <0.05).There were no significant differences in the reactivity evaluation of dignity and social support dimension between the two groups (P >0.05).Conclusions The reactivity evaluation of healthy system in the comprehensive maintenance model is higher.It can provide timely and convenient PICC service and meet the expects and demands of patients.
