Precise management of the activity dose is a core component of the(early mobilization,EM)plan for ICU patients.However,the lack of clinical practice guidelines related to EM dose of existing programs hinders the implementation and development of EM in ICU patients to some extent.Therefore,this review focuses on 4 aspects,covering the definition of activity dose,assessment tools,the current clinical implementation status,and implications for future nursing.The aim is to systematically review the assessment tools and intervention strategies for the activity dose of EM in ICU patients,providing a reference for optimization of EM programs.

Objective To establish a scheme of immunosuppressant(tacrolimus)tube administration after lung transplantation and evaluate the effect.Methods Utilizing evidence summary and the Delphi method with the Structure-Process-Outcome(SPO)model,a tacrolimus administrating via feeding tubes scheme was established for lung transplantations,incorporating 5 aspects"medication management""risk assessment""enteral feeding implementation""process monitoring"and"evaluation and feedback"from July to September 2023.A convenience sampling method was employed to select patients with lung transplant surgery of a tertiary hospital in Zhejiang Province from November 2023 to June 2024.Among them,18 patients admitted from March to June 2024 were designated as an experimental group,receiving the developed tacrolimus enteral feeding administration plan;18 patients admitted from November 2023 to February 2024 were designated as a control group,receiving standard enteral feeding administration measures.The standard trough concentration of tacrolimus,the coefficient of variation of tacrolimus trough concentration,the daily dosage of tacrolimus and its coefficient of variation,and the rate of achieving the target trough concentration of tacrolimus were compared between the 2 groups.Results Of the initially recruited subjects,15 in the experimental group and 18 in the control group were included in the final analysis.After intervention,the coefficient of variation of trough concentrations and daily doses of tacrolimus in the experimental group were lower than those in the control group,while the rate of achieving target trough concentrations was higher,with all differences being statistically significant(P＜0.05).There was no statistically significant difference in the comparison of standardized blood drug concentrations and the coefficient of variation of daily doses between the 2 groups(P＞0.05).Conclusion The tacrolimus administrating via feeding tubes scheme for lung transplantations based on the SPO model is scientific and practical,providing clinical references for the use of tacrolimus enteral medication after lung transplantation,in order to promote the standardization of tacrolimus enteral administration.

Objective To conduct a scoping review of the current state of research on the application of virtual reality technology in psychological interventions for cancer patients,clarifying its types,forms,contents,intervention effects,and outcome indicators,and to provide the improvement of mental health in cancer patients.Methods A literature search was conducted on PubMed,Embase,Web of Science,Scopus,Cochrane Library,China National Knowledge Infrastructure,and Wanfang Data up to October 11,2023.The selected literature was screened,included,and analyzed for content summary.Results A total of 22 studies were included,involving both non-immersive and immersive virtual reality technologies,with various systems or programs used for intervention.The primary interventions include virtual reality relaxation therapy,virtual reality exposure therapy,and virtual reality reminiscence therapy.The outcome indicators primarily include anxiety,depression,distress,pain,fatigue,sleep,quality of life,coping,and side effects of virtual reality.Conclusion The use of virtual reality technology for psychological interventions in cancer patients offers a variety of forms and rich content,which has a positive impact on improving the physical and mental health of cancer patients.However,there is significant heterogeneity in the content elements and outcome measure tools,leading to certain limitations in its application.In the future,the specific needs of cancer patients should be considered,and the procedural norms for virtual reality-based psychological interventions should be explored.

Objective:To analyze the risk factors of bronchopulmonary dysplasia(BPD)in very preterm infants(VPI), and to provide scientific basis for the prevention and treatment of BPD in VPI.Methods:A prospective multicenter study was designed to collect the clinical data of VPI in department of neonatology of 28 hospitals in 7 regions from September 2019 to December 2020.According to the continuous oxygen dependence at 28 days after birth, VPI were divided into non BPD group and BPD group, and the risk factors of BPD in VPI were analyzed.Results:A total of 2 514 cases of VPI including 1 364 cases without BPD and 1 150 cases with BPD were enrolled.The incidence of BPD was 45.7%.The smaller the gestational age and weight, the higher the incidence of BPD( P<0.001). Compared with non BPD group, the average birth age, weight and cesarean section rate in BPD group were lower, and the incidence of male infants, small for gestational age and 5-minute apgar score≤7 were higher( P<0.01). In BPD group, the incidences of neonatal respiratory distress syndrome(NRDS), hemodynamically significant patent ductus arteriosus, retinopathy of prematurity, feeding intolerance, extrauterine growth restriction, grade Ⅲ~Ⅳ intracranial hemorrhage, anemia, early-onset and late-onset sepsis, nosocomial infection, parenteral nutrition-associated cholestasis were higher( P<0.05), the use of pulmonary surfactant(PS), postnatal hormone exposure, anemia and blood transfusion were also higher, and the time of invasive and non-invasive mechanical ventilation, oxygen use and total hospital stay were longer( P<0.001). The time of starting enteral nutrition, cumulative fasting days, days of reaching total enteral nutrition, days of continuous parenteral nutrition, days of reaching 110 kcal/(kg·d) total calorie, days of reaching 110 kcal/(kg·d) oral calorie were longer and the breastfeeding rate was lower in BPD group than those in non BPD group( P<0.001). The cumulative doses of amino acid and fat emulsion during the first week of hospitalization were higher in BPD group( P<0.001). Multivariate Logistic regression analysis showed that NRDS, invasive mechanical ventilation, age of reaching total enteral nutrition, anemia and blood transfusion were the independent risk factors for BPD in VPI, and older gestational age was the protective factor for BPD. Conclusion:Strengthening perinatal management, avoiding premature delivery and severe NRDS, shortening the time of invasive mechanical ventilation, paying attention to enteral nutrition management, reaching whole intestinal feeding as soon as possible, and strictly mastering the indications of blood transfusion are very important to reduce the incidence of BPD in VPI.
