Objective:To develop a nutritional management protocol for head and neck cancer (HNC) patients undergoing radiotherapy based on evidence-based methodology, and to evaluate its clinical effectiveness.Methods:Relevant literature on nutritional management in radiotherapy for HNC patients was systematically searched. After evidence extraction, a preliminary protocol was drafted and finalized through expert consensus. The finalized protocol included five timepoints during hospitalization, covering six components and 35 nursing and clinical care items. A quasi-experimental design was adopted. Using convenience sampling, 100 HNC patients admitted to Jinhua Municipal Central Hospital from October 2022 to June 2024 were enrolled. Patients treated between October 2022 and July 2023 formed the control group ( n=50), and those treated from September 2023 to June 2024 comprised the intervention group ( n=50). The control group received routine care, while the intervention group was managed with the evidence-based nutrition protocol. Body weight and nutrition-related laboratory indicators were measured before radiotherapy, at week 4, and at the end of week 6. Results:At week 4 of radiotherapy, the intervention group had a higher lymphocyte count than the control group, with statistically significant differences ( P<0.05). At week 6, total serum protein, serum albumin, and lymphocyte counts were all higher in the intervention group, with statistically significant differences ( P<0.05) . Conclusions:The evidence-based nutritional management protocol developed for HNC patients undergoing radiotherapy effectively improves nutritional status. It provides a valuable reference for healthcare professionals in clinical practice.

Objective:To analyze the clinical features and prognosis of patients with lymphoplasmacytic lymphoma/Waldenstr?m macroglobulinemia (LPL/WM) transformed into diffuse large B-cell lymphoma (DLBCL) .Methods:This study retrospectively analyzed the clinical data of five patients with LPL/WM transformed to DLBCL diagnosed and treated at a multicenter hospital in Hunan Province from December 2020 to April 2023. Clinical manifestations, treatment regimens, and therapeutic efficacy before and after the transformation were compared.Results:Of the five patients, four were male and one was female, with a median age of 64.0 (57.0–80.0) years, all of whom had abnormally increased β 2-microglobulin levels at diagnosis, and two were combined with increased lactate dehydrogenase levels. The MYD88 L265P mutation was detected in 4 patients, whereas 1 carried the FAT1 and NOTCH1 mutations, and none demonstrated CXCR4 mutations. Three patients were negative for the TP53 mutation, and two were not tested. Before transformation, three patients were treated with Bruton tyrosine kinase inhibitor therapy, and one patient was treated with the bendamustine plus rituximab regimen. All patients eventually transformed into non-growth center-derived DLBCL, with a median time to conversion of 11.8 (4.0–19.0) months, and most of them presented with weight loss, lymph node enlargement, splenomegaly, and extranodal involvement. Posttransformation, the patients were mainly treated with the rituximab, cyclophosphamide, hydroxydaunorubicin, oncovin, and prednisone (R-CHOP) regimen, with an optimal outcome of partial remission. Disease progression occurred in 4 of the patients, with a median overall survival of 16.8 (10.0–26.0) months. Conclusion:Transformation from LPL/WM to DLBCL is rare. Patients should remain highly vigilant for transformation if they develop rapidly enlarging lymph nodes and/or newly involved lymph nodes, worsening systemic symptoms, and declining body mass. R-CHOP regimen may induce a partial response in some cases; however, the overall prognosis remains poor.

Objective The aim is to understand the common scenarios of non-medical use of prescription opioids(NMUPO)and analyze the potential facilitating and hindering factors in the regulatory process of NMUPO from the perspective of healthcare professionals.Methods Healthcare professionals in local hospitals were surveyed through a two-stage purposive sampling from June to August 2022 in Ningbo,China.The survey was conducted using a semi-structured questionnaire on topics,and thematic analysis were used to identify and summarise key themes and patterns.Results A total of 75 participants were included,the average age was(43.9±7.2)years,and 54(72.0%)were male.The most common NMUPO scenarios involved middle-aged males pretending acute severe pain to obtain injectable opioids.The facilitating and hindering factors related to the regulation of NMUPO can be categorized into three types:institutional governance,technical support,and individual behaviors.At the institutional level,facilitating factors included strict national prescribing policies and local"narcotic drug card"systems,while barriers comprised incomplete lists of controlled substances.At the technological support level,facilitating factors included the establishment of regional health information platforms,while barriers included the lack of standardized prescription guidelines and diagnostic decision-support tools.At the individual level,facilitating factors included the public's cautious attitude toward drug misuse,while barriers included strained doctor-patient relationships.Conclusion China still faces significant challenges in addressing NMUPO and urgently needs to improve the existing regulatory system.It is recommended that reforms be carried out in areas such as pharmaceutical control mechanisms,drug treatment and rehabilitation services,preventive health education activities,and the optimized use of health information systems.

Objective:To explore the application of bridge-in, objective, pre-assessment, participatory learning, post-assessment, and summary (BOPPPS) combined with knowledge point auction-based learning in the internship teaching of pediatric general surgery nursing students.Methods:Ninety nursing students completing internships in the General Surgery Department of Children's Hospital, Zhejiang University School of Medicine from July 2022 to April 2024 were selected as the research subjects. According to the order of admission, they were divided into control group (July 2022 to May 2023) and experimental group (June 2023 to April 2024), with 45 students in each group. The control group received conventional teaching, while the experimental group received BOPPPS teaching combined with knowledge point auction-based learning. Theoretical and practical training assessment scores were compared between the two groups. Additionally, a survey on the degree of satisfaction with the teaching was administered upon internship completion . Data were analyzed using t-tests with SPSS 26.0. Results:The theoretical scores of nursing students in the experimental group were higher than those in the control group, and the difference was statistically significant; The performance of the experimental group's nursing students in practical training assessment was higher than that of the control group [peripheral venous puncture catheterization: (27.62±2.10) vs. (22.41±3.80)]; Gastrointestinal decompression technique: (22.82±1.70) vs. (18.21±2.91); Rescue of anaphylactic shock: (16.52±3.13) vs. (21.32±2.41); There was a statistically significant difference in the evaluation of teacher guidance ability between the two groups of nursing students in terms of intestinal fistula nursing (14.11±2.70) vs. (17.90±1.93). However, there was no statistically significant difference in the satisfaction score of the experimental group nursing students in other aspects of teaching compared to the control group, and the difference was statistically significant.Conclusions:BOPPPS combined with knowledge point auction-based learning improves knowledge mastery in clinical teaching for pediatric general surgery interns, enhance operational confidence, and is readily accepted by students.

Objective To analyze the short- and long-term therapeutic effects of heart transplantation in children. Methods A retrospective study was conducted on recipients and donors who underwent heart transplantation at the 7th People’s Hospital of Zhengzhou from May 2018 to August 2023, analyzing their clinical characteristics, surgical data, postoperative complications, and survival rates. Results A total of 22 children underwent heart transplantation, including 14 males and 8 females, with a median age of 13.5 (10.0, 15.0) years and a median weight of 41.9 (30.5, 55.4) kg. The primary diseases included: dilated cardiomyopathy in 16 patients, hypertrophic cardiomyopathy in 1 patient, myocardial dysplasia in 3 patients, right ventricular dysplasia in 1 patient, and congenital heart disease with abnormal coronary artery origin in 1 patient. The median age of the donors was 21.0 (13.0, 29.0) years, and the median weight was 50.5 (47.3, 75.0) kg. The blood types of the donors and recipients were the same, with type A in 10 patients, type B in 5 patients, type O in 5 patients, and type AB in 2 patients. Before transplantation, all children had a New York Heart Association cardiac function grade Ⅳ, with 1 patient assisted by intra-aortic balloon pump (IABP), 3 patients assisted by extracorporeal membrane oxygenation (ECMO), 2 patients assisted by continuous renal replacement therapy (CRRT), and 2 patients on mechanical ventilation. Nine patients met the criteria for emergency child status allocation, and the panel reactive antibody level in the patients was<10%. The median cold ischemic time of the donor heart was 355.0 (262.0, 395.5) min, the median aortic cross-clamping time was 45.0 (38.3, 51.3) min, the median mechanical ventilation time was 22.5 (16.8, 52.5) h, the median postoperative hospital stay was 29.5 (20.0, 43.0) d, and the median intensive care unit stay was 6.0 (5.0, 8.3) d. After surgery, 4 patients were assisted by ECMO, 2 patients by CRRT, and 7 patients developed complications, including lung fungal infection in 6 patients, liver and kidney dysfunction in 1 patient, local wound non-union and mediastinal infection in 1 patient, and multiple organ failure in 1 patient. Kaplan-Meier curve analysis showed that the survival rates of children after surgery were 91.3% at 1 year and 3 years; the survival rates of adult heart transplant recipients at our center were 86.7% and 73.8% at 1 year and 3 years, respectively, indicating that the survival rate of children with heart transplantation was higher than that of adult patients. Conclusion Heart transplantation is an effective treatment for end-stage heart failure in children, and the short- and long-term survival rates of children with heart transplantation are superior to those of adults. There are still many difficulties to be solved in pediatric heart transplantation, requiring joint efforts from society and the medical community.

Objective:To apply digital analysis to quantify hyperechogenicity of substantia nigra, and explore its clinical value for diagnosis of Parkinson′s disease (PD).Methods:The cross-sectional study included 652 PD patients (PD group) and 99 healthy controls (healthy control group) from November 2017 to October 2020 in Tongji Hospital of Tongji Medical College of Huazhong University of Science and Technology. All subjects underwent transcranial sonography. The diagnostic accuracy of substantia nigra hyperechogenicity using digital analysis was compared with that in a manual measurement in PD. Furthermore, the receiver operating characteristic (ROC) curve analysis was applied to explore its diagnosis value in PD.Results:There were 482 subjects including 400 in the PD group and 82 in the healthy control group, whose quantified results of substantia nigra hyperechogenicity could be used for analysis. The ROC analysis showed that the area under the curve of the quantified larger substantia nigra hyperechoic region detection for diagnosing PD was 0.858 (95% CI 0.805-0.910), the sensitivity was 87.8%, and the specificity was 73.2%, consistent with that of doctors (area under the curve: 0.884). Further more, among these PD patients, there was no correlation between larger substantia nigra hyperechogenicity and age, age of onset, course of disease, non-motor symptoms, and motor symptoms (all P>0.05). Conclusions:Digital analysis was used to quantify the changes in substantia nigra hyperechogenicity in this seudy. The results showed that diagnostic accuracy for PD based on digital analysis was consistent with that of experienced clinicians.
