Objective:To deeply explore the experience and feelings of postpartum weight management in primiparas, so as to provide reference for optimizing postpartum management strategies.Methods:This study was qualitative. From May to June 2023, purposive sampling was used to select 15 primiparas who underwent postpartum follow-up at the Affiliated Suzhou Hospital of Nanjing Medical University as the research subject for semi-structured interviews. The Colaizzi 7-step analysis method was used to analyze data and extract themes.Results:The lived experience of postpartum weight management in primiparas was extracted into three themes and 11 sub-themes, including cognitive differences in postpartum weight management (awareness of importance and adoption of positive behaviors, neglect and avoidance), facilitators and obstacles in weight management (facilitators included self-expectations, positive evaluations and feedback from others, beneficial experiences, while obstacles included eating and exercise behavior disorders, physical symptom interference, role conflicts, negative emotions), and a desire to receive support from multiple aspects (continuous information support from medical institutions, support and acceptance from families and society) .Conclusions:Primiparas have a relatively insufficient cognition of postpartum weight management, and the weight management process is influenced by many factors. Medical and nursing staff should adopt effective strategies to correct cognitive biases in maternal weight management, make full use of facilitators, actively respond to obstacles, and pay attention to multiple sources of support, so as to promote postpartum recovery.

Objective:To construct a thirst management scheme for adult surgical patients and provide practical guidance for nurses to carry out perioperative thirst management.Methods:From April to May 2023, literature search was conducted to extract domestic and foreign evidence related to thirst, and after group discussion, a preliminary management plan for thirst in adult surgical patients was constructed. From May to June 2023, 18 experts were selected for two rounds of Delphi expert letter consultation, and a formal plan for thirst management of adult surgical patients was discussed and revised according to expert opinions.Results:A total of 18 experts completed two rounds of expert letter consultation. The effective recovery rate of the questionnaire was 100.00% and the expert authority coefficient was 0.915. The coefficients of variation for the importance and operability scores of the first round of expert inquiry were 0.05-0.25 and 0.06-0.42, respectively, and the Kendall's harmony coefficients were 0.224 and 0.184 ( P<0.01). The coefficients of variation for the importance and operability scores of the second round of inquiry were 0.05-0.23 and 0.06-0.24, respectively, and the Kendall's harmony coefficients were 0.166 and 0.154 ( P<0.01). The final thirst management scheme included five primary items (preliminary preparation, identification and evaluation, preoperative relief strategies, postoperative intervention measures and effectiveness evaluation) and 23 secondary items. Conclusions:The thirst management scheme for adult surgical patients constructed in this study is scientific and comprehensive, which can provide a reference basis for clinical practice.

Objective:To explore the changing trajectory of psychological distress in young and middle-aged patients during peridialysis period.Methods:Totally 122 patients in the peridialysis period were investigated with the Self-Designed General Data Questionnaire,Distress Screening Scale(DSS),Connor-Davidson Resilience Scale(CD-RISC),Social Support Revalued Scale(SSRS)and Self-Perceived Burden Scale(SPBS)at the time of diag-nosis,initial dialysis,and dialysis for 1 month,2 months and 3 months,respectively.The growth mix model was used to identify trajectory categories.Results:The time main effect of scores of DSS,CD-RISC and SPBS in peridi-alysis patients was statistically significant(Ps＜0.05),the scores of DSS and SPBS were the highest at the initial dialysis and the lowest at 3 months of dialysis.The CD-RISC scores were the lowest at the first dialysis and the highest at 3 months of dialysis.The trajectory of psychological distress was divided into 3 types,namely continuous high level(26.20％),high level decline(40.72％),and medium-low level decline(33.08％).Conclusion:The psychological distress of young and middle-aged peridialysis patients shows different trajectories from diagnosis to regular dialysis.Clinical staff should pay more attention to the psychological status of the first-time dialysis pa-tients.

Objective To investigate the current postoperative physical activity levels of lung cancer patients after a month and to analyze the influencing factors.Methods From January to December 2023,a total of 1,195 lung cancer patients from 16 hospitals in eastem,central and westem China were selected as the survey subjects by the convenient sampling method.A cross-sectional survey was conducted by General Information Questionnaires,Health-Related Physical Fitness Surveys,MD Anderson Symptom Inventory,Hospital Anxiety and Depression Scale,Social Support Rating Scale,Self-Rated Abilities for Health Practices Scale,and the International Physical Activity Questionnaire.Results 36 questionnaires with missing data exceeding 10％and 13 duplicate questionnaires were excluded,resulting in the analysis of 1,146 questionnaires.After a month postoperatively,lung cancer patients with moderate and low levels of physical activity were 732(63.9％)and 204(17.8％),respectively.Multivariate regression analysis showed that the influencing factors included residence,average monthly family income,regional lymph node staging,family history of lung cancer,grip strength,hemoglobin,and depression score(P＜0.05).Conclusion The physical activity level of lung cancer patients a month after surgery is influenced by a combination of sociodemographic,disease-related,health-related physical fitness,and psychological factors.Clinical healthcare professionals should accurately assess the physical activity levels of lung cancer patients,identify those with insufficient physical activity,and develop and implement personalized intervention strategies based on their physical condition and potential influencing factors to enhance their physical activity levels and improve their quality of life.

Objective To construct a perioperative exercise program for older frail patients with colorectal cancer,and to verify its effect.Methods Based on Goal-directed Theory and literature review,expert consultation was carried out to establish the perioperative exercise program for older frail patients with colorectal cancer.Then,from July to December 2022,the perioperative exercise program was established for older frail patients with colorectal cancer hospitalized in the General Surgery Department of a tertiary A hospital in Suzhou by convenience sampling method for preliminary application.It was divided in to the intervention group and the control group by the ward.The intervention group was applied with the constructed perioperative exercise program on the basis of routine perioperative nursing.The safety,feasibility and intervention effect of the program were evaluated.Results 15 experts were included for 2 rounds of expert consultations.The authority coefficient was 0.880;the coefficient of variation was＜0.250;the Kendall concordance coefficient was 0.167 and 0.224,respectively.The final program contained 4 stages:preoperative exercise,postoperative bed rest,sitting and standing exercise.In the end,54 specific interventions were constructed.During the preliminary application,all the patients completed the program.Generalized estimation equation showed that,on the interaction effect,there was no statistical difference(P=0.752);there were significant differences on the intervention effect and the time effect(P＜0.05).At discharge,there were significant differences in timed up and go test and Barthel Index between the 2 groups(P＜0.05).Only 2 patients experienced mild pain in the intervention group,and no other adverse events occurred.Conclusion The perioperative exercise program for older frail patients with colorectal cancer,based on Goal-directed Theory,is scientific,reliable and safe.It has been preliminarily verified in improving postoperative physical function,activities of daily living and early postoperative recovery of elderly frail patients with colorectal cancer.

Objective To evaluate the interventional effects of virtual reality(VR)on cancer patients in pain,anxiety,cognitive function,upper limb function and quality of life.Methods Randomised controlled trials(RCTs)using VR technology on cancer patients were retrieved from databases of CNKI,Wanfang Database,SinoMed,VIP,PubMed,Web of Science,Embase,PsycINFO and Cochrane Library,from the inception of the databases to March 2023.Two reviewers independently examined and screened the literatures,followed by evaluation of the quality and extraction of relevant themes.Meta-analysis was conducted by using RevMan 5.3 to analyse the acquired data.Results A total of 9 RCTs involving 727 patients were included.The meta-analysis demonstrated that VR technology alleviated pain intensity in cancer patients[SMD=-1.31,95%CI(-1.96 to-0.66),P<0.001],relieved anxiety[SMD=-0.96,95%CI(-1.62 to-0.31),P=0.004],improved cognitive function[SMD=3.37,95%CI(1.74 to 5.00),P<0.001],and improved quality of life of cancer patients[SMD=0.67,95%CI(0.38 to 0.96),P<0.001].However,it posed unclear effect on upper limb function[SMD=-0.57,95%CI(-1.40 to 0.26),P=0.18].Conclusion VR technology shows potentials in alleviation of pain,reduction of anxiety and improvement of cognitive function and the quality of life in cancer patients,but it remains uncertain effect on upper limb function.However,due to heterogeneity in some of the results,more high-quality studies are required to validate the interventional effects of VR technology on cancer patients.

Objective To understand the current situation of protective mask wearing behavior of health care workers(HCWs),analyze the influencing factors for the failure to wear medical protective masks in a standard manner,and provide basis for the improvement of mask-wearing related training.Methods From June 2022 to March 2023,staff in a tertiary first-class hospital were selected as the research object.Real-time quantitative fitness testing using aerosol condensation particle counting method was applied to test 5 commonly used medical protective masks available in the market.Fitness factor changes of the testing instrument and assistance from professional per-sonnel were needed to comprehensively estimate the wearing condition of medical protective masks.Participants were surveyed through a self-made general information questionnaire.Heads and faces of participants were scanned by three-dimensional(3D)laser scanning technology,and scanned images were imported into Geomagic Studio 2013 software to measure head and face dimensions.Results A total of 222 HCWs were investigated,991 real-time tests and 208 times of 3D scanning were conducted.221(22.30％)tests showed failure of participants in wearing masks in a standard manner.The non-standard wearing rates of 5 types of medical protective masks were 30.56％,25.62％,25.87％,23.15％,and 7.35％,respectively.The non-standard mask-wearing rates showed statistically significant difference between groups categorized in terms of medical protective masks with different shapes,partici-pants'occupation,time of last training for wearing medical protective masks,and participants'experience in pre-vention and control of respiratory infectious disease(all P＜0.05).There were no statistically significant differences in non-standard mask-wearing rate between groups with different brands and sizes of medical protective masks,as well as gender and department of participants,etc.(all P＞0.05).The body mass index(BMI)was significantly different among participants who wear foldable medical protective masks in the standard and non-standard manner(both P＜0.05).Conclusion Wearing medical protective masks by HCWs in a non-standard manner is influenced by multiple factors.It is recommended to conduct real-time testing before formal quantitative fitness testing,so as to save time and improve testing efficiency.When conducting training on wearing medical protective masks in the fu-ture,targeted training should be provided based on mask shape and focus on logistics personnel,interns,individuals with high BMI,those who have never received training on wearing medical protective masks,and those who have never participated in the prevention and treatment of respiratory infectious diseases.
