RESUMEN
BACKGROUND: Venous thromboembolism (VTE) as the most common cancer-associated complication has become the second death-causing reason among cancer patients. The management of VTE in patients with lung adenocarcinoma should focus on early and timely detection of risk factors. The aim of the study is to investigate the current situation of VTE in patients with lung adenocarcinoma treated with anti-tumor therapy and then explore the risk factors associated with the occurrence of VTE during anti-tumor therapy for early detection and screening of VTE. METHODS: The present study included patients diagnosed as lung adenocarcinoma undergoing anti-tumor therapy in First Affiliated Hospital of Nanjing Medical University between December 2019 and May 2021. The risk factors were identified via univariate and multivariate Cox analysis. The incidence of independent risk factors were investigated through Kaplan-Meier curves combined with Log-rank test. RESULTS: The results of univariate and multivariate Cox regression showed that history of VTE, targeted therapy and radiotherapy were risk factors for VTE in patients with lung adenocarcinoma treated with anti-tumor therapy (P<0.05). Furthermore, the results of Kaplan-Meier curves and Log-rank tests indicated the incidences of VTE in patients with history of VTE, targeted therapy and radiotherapy were higher (P<0.05). CONCLUSIONS: History of VTE, radiotherapy and targeted therapy are found as independent risk factors for the occurrence of VTE, which should be identified and monitored for reduction of VTE incidence.â©.

AIMS AND OBJECTIVES: To explore the trajectories of self-care behaviours in patients with chronic obstructive pulmonary disease based on the latent class growth model and investigate the predictors of each trajectory based on the capability opportunity motivation and behaviour model. BACKGROUND: Studies on self-care behaviours of patients with chronic obstructive pulmonary disease are mainly cross-sectional surveys. However, little is known about longitudinal trends of self-care behaviours changes among those population. DESIGN: This was a prospective observational research performed according to STROBE Checklist. METHODS: One hundred and nineteen patients with chronic obstructive pulmonary disease were followed up at baseline, 3 and 6 months. Data collection included the scores of self-care behaviours, specific demographic and clinical characteristics, and scores for the predictors. A latent class growth model was used to explore the self-care behaviours trajectories. Multiple logistic regression analysis was conducted to identify predictors of self-care behaviours trajectories. RESULTS: Three trajectories in the self-care behaviours of patients with chronic obstructive pulmonary disease were found: a persistently negative trajectory, a maintenance trajectory after a slight increase and an active trajectory with a slow upward improvement in self-care behaviours. Medical insurance and access to medical resources were the predictors of self-care behaviours. CONCLUSION: The patients with poor medical resources and medical insurance are at high risk for the poor self-care behaviours and the negative trajectory. Thus, dynamic and individualised intervention should be continuously provided to ensure patients acquire adequate medical resources to comprehensively improve self-care behaviours. RELEVANCE TO CLINICAL PRACTICE: People with better self-care trajectory may be patients who receive more medical resources or have less financial burden, which will help with the early identification of high-risk patients with a negative self-care trajectory. Intervention guided by Behaviour Change Wheel Theory should be conducted dynamically for patients for patients with different trajectories. PATIENT OR PUBLIC CONTRIBUTION: Thank the patients and their families for their cooperation in data collecting in this study.

OBJECTIVE: To evaluate the effectiveness of motivational interviewing (MI) for COPD in behavioral changes and health outcomes, and also verify the reliability of results in conjunction with trial sequential analysis and the Grading of Recommendations Assessment, Development, and Evaluation tool. METHODS: Studies that implemented MI interventions for COPD patients were systematically searched by eight databases from inception to December 2021. Study screening, quality assessment, data extraction, and meta-analysis were conducted according to Cochrane standards. RESULTS: Twenty-one studies involving 2344 patients were included. The results of meta-analyses indicated that MI made significant improvement in self-efficacy, lung function, quality of life, emotion, and COPD-related admission, but not in self-management and exercise capacity. Subgroup analyses found that the intervention duration was inversely associated with effect size for both self-efficacy and negative emotion severity. The trial sequential analysis showed MI improved patients' lung function and reduced COPD-related hospitalization with certainty, but the findings for exercise capacity need to be confirmed by further research. CONCLUSIONS: This systematic review suggested the positive effects of MI on self-efficacy, lung function, quality of life, emotion and COPD-related hospitalization. To make a firm conclusion, more well-designed clinical trials with bigger sample sizes required. PRACTICE IMPLICATIONS: Clinical and community nurses can use MI for COPD to increase healthy behaviors. TRIAL REGISTRATION: CRD42021278674.

BACKGROUND: Venous thromboembolism has been a major public health problem and caused a heavy disease burden. Venous thromboembolism clinical decision support system was proved to have a positive influence on the prevention and management of venous thromboembolism. As the direct users, nurses' acceptance of this system is of great importance to support the successful implementation of it. However, there are few relevant studies to investigate nurses' acceptance and the associated factors are still unclear. OBJECTIVE: To investigate the determinant factors of nurses' acceptance of venous thromboembolism clinical decision support system with the modified Unified Theory of Acceptance and Use of Technology. METHODS: We designed a questionnaire based on the modified Unified Theory of Acceptance and Use of Technology and then a cross-sectional survey was conducted among nurses in a tertiary hospital in Nanjing, China. Statistically, a Structural Equation Modeling -Partial Least Squares path modeling approach was applied to examine the research model. RESULTS: A total of 1100 valid questionnaires were recycled. The modified model explained 74.7%, 83.0% and 86% of the variance in user satisfaction, behavioral intention and user behavior, respectively. The results showed that performance expectancy (ß = 0.254, p = 0.000), social influence (ß = 0.136, p = 0.047), facilitating conditions (ß = 0.245, p = 0.000), self-efficacy (ß = 0.121, p = 0.048) and user satisfaction (ß = 0.193, p = 0.001) all had significant effects on nurses' intention. Although effort expectancy (ß = 0.010, p = 0.785) did not have a direct effect on nurses' intention, it could indirectly influence nurses' intention with user satisfaction as the mediator (ß = 0.296, p = 0.000). User behavior was significantly predicted by facilitating conditions (ß = 0.298, p = 0.000) and user intention (ß = 0.654, p = 0.001). CONCLUSION: The research enhances our understanding of the determinants of nurses' acceptance of venous thromboembolism clinical decision support system. Among these factors, performance expectancy was considered as the top priority. It highlights the importance of optimizing system performance to fit the users' needs. Generally, the findings in our research provide clinical technology designers and administrators with valuable information to better meet users' requirements and promote the implementation of venous thromboembolism clinical decision support system.

BACKGROUND: Improving patient activation can lead to better health outcomes among patients with chronic obstructive pulmonary disease (COPD). However, no studies have focused on the issue of activation in patients with COPD in China. PURPOSE: This study was designed to explore the status of activation in patients with COPD in China and explicate the significant influencing factors. METHODS: One hundred seventy patients with COPD were recruited using a convenience sampling method from eight tertiary and secondary hospitals in Nanjing, China. Sociodemographic, clinical, and patient-reported factor data were collected. Univariate analysis and multivariate linear regression were performed. RESULTS: Only 10.6% of the patients were identified as activated for self-management. Multivariate linear regression analysis revealed four explanatory elements as significantly associated with patient activation, including social support (ß = .463, p < .001), free medical insurance (ß = .173, p = .007), smoking status (ß = -.195, p = .002), and health status (ß = -.139, p = .04). CONCLUSIONS/IMPLICATIONS FOR PRACTICE: The findings of this study indicate that a minority of patients with COPD are activated for self-management in China. Having a higher level of patient activation was associated with having better social support, having free medical insurance, being a nonsmoker, and having a better health status. Creating a supportive environment, promoting smoking cessation, and improving medical security and health status may be considered as potential strategies to activate patients into better self-management.

INTRODUCTION: This study aimed to examine the effectiveness of high-intensity interval training (HIIT) on pulmonary function and exercise capacity in individuals with chronic obstructive pulmonary disease (COPD). METHODS: Ten databases (PubMed, the Cochrane Library, Web of Science, EMBASE, MEDLINE, CINAHL, CNKI, Wanfang, Weipu, and CBM) were searched for relevant articles published from inception to 30 June 2020. Studies were included if they were randomized controlled trials (RCTs) comparing a HIIT group with usual care or other training groups. Quality was assessed using the Physiotherapy Evidence Database (PEDro) scale, and the overall quality of evidence was assessed using the GRADE approach. The primary outcomes were peak VO2 and FEV1% predicted, and the secondary outcomes were FEV1/FVC, peak VE, peak WR, 6MWD, dyspnea, health-related quality of life, and adverse event. RESULTS: Twelve articles (689 patients) were included. HIIT was shown to have a positive effect on exercise capacity (peak WR, 6MWD), pulmonary function (FEV1% pred, peak VE), dyspnea, and quality of life. However, sensitivity analyses for dyspnea were unstable, and the result changed from positive to negative after removing one study (SMD = - 0.13, 95% CI [- 0.44, 0.17], P = 0.40). CONCLUSIONS: HIIT could improve pulmonary function, exercise capacity, and quality of life but may not decrease dyspnea in patients with COPD. It can be recommended as a safe and effective exercise modality in rehabilitation programs. Given that the overall results were based on a limited number of studies with significant heterogeneity and some of the results were based on low GRADE rating evidence, more high-quality, larger sample size, multicenter, and long-term follow-up RCTs are needed to confirm the clinical efficacy of HIIT in patients with COPD.

OBJECTIVE: To investigate the care needs of dying patients and their family caregivers in hospice and palliative care in mainland China. METHODS: A search for English and Chinese quantitative and qualitative studies was performed using the following English databases: PubMed (Medline), CINAHL and PsycINFO, as well as Chinese databases: SinoMed and CNKI. The records were independently screened by two reviewers and critiqued using Joanna Briggs Institute Critical Appraisal tools. All quantitative data were transformed into qualitative data, which were converted into textual descriptions. Due to the diversity of included studies, a three-step analysis was performed: narrative summary, thematic analysis and presentation of integrated results in a narrative form. The qualitative findings were pooled using the meta-aggregation approach. RESULTS: The literature search identified 2964 papers after removing duplicates, from which 18 were included (9 quantitative and 9 qualitative studies). All studies were conducted in mainland China. Quantitative studies involved cross-sectional surveys, and qualitative studies involved interviews for data collection. Two synthesised results of patients' needs were identified, including needs to be comfortable and experience a good death. Another two synthesised results of family caregivers' needs included needs to care for and improve the quality of life of patients, and to care for themselves well. CONCLUSION: This study identified that patients and family caregivers have an increasing demand for professional care at the end of life. Professionals, especially nurses, should enact a patients' demand-centred practice to overcome the challenges of organisation, education, emotion and communication to provide high-quality end-of-life care.

BACKGROUND: Peripherally-inserted central catheter-related venous thrombosis has serious complications including the loss of vascular access, recurrent venous thrombosis, and post-thrombotic syndrome. Current guidelines recommend non-pharmacological strategies to prevent peripherally-inserted central catheter-related venous thrombosis. There is little evidence for the effectiveness of handgrip exercise on the prevention of peripherally-inserted central catheter-related venous thrombosis. OBJECTIVES: To examine the effectiveness of handgrip exercise using an elastic ball to prevent peripherally-inserted central catheter-related venous thrombosis in patients with solid cancers. DESIGN: A randomized controlled trial. SETTINGS: One teaching hospital in Nanjing, China. PARTICIPANTS: In total, 120 subjects with solid cancers were eligible; each had a new peripherally-inserted central catheter. They were recruited and randomly assigned into two exercise groups and one control group. METHODS: Subjects from exercise groups 1 and 2 performed a 3-week, 25-repetition handgrip exercise, 3 and 6 times daily, respectively. The control group subjects performed a gentle limb exercise with no frequency and intensity requirements. Ultrasound was used to detect venous thrombosis development and examine axillary vein blood flow over the three points. RESULTS: There were 32 cases of peripherally-inserted central catheter-related venous thrombosis detected. Two venous thrombosis cases in the control group were symptomatic, but all venous thrombosis cases in the exercise groups were asymptomatic. All venous thromboses were partial. There were significant differences in the incidence of venous thrombosis among the three groups (χ2â¯=â¯12.813, pâ¯=â¯0.002; χ2â¯=â¯9.340, pâ¯=â¯0.009; χ2â¯=â¯11.480, pâ¯=â¯0.003; and χ2â¯=â¯10.534, pâ¯=â¯0.005, respectively) at days 2, 3 and 21. The incidence of venous thrombosis in the two exercise groups was lower than that in the control group over the 3 time points (all, pâ¯<â¯0.05). The between-group effects and interaction effect in vein maximum velocity and time-mean flow velocity showed significant differences (Fâ¯=â¯4.180, pâ¯=â¯0.025; Fâ¯=â¯4.010, pâ¯=â¯0.045; and Fâ¯=â¯2.928, pâ¯=â¯0.025) at days 2, 3, and 21, respectively. The axillary vein blood flow parameters in the control group were lower than those in the two exercise groups at day 21 (all, pâ¯<â¯0.05). However, no significant differences occurred in the incidence of venous thrombosis and axillary vein blood flow parameters between the two exercise groups. CONCLUSION: Handgrip exercise using an elastic ball daily for three weeks could decrease the incidence of peripherally-inserted central catheter-related venous thrombosis. The method is simple, with no negative consequence reported. Further studies are required to confirm this conclusion and to explore the optimal frequency of handgrip exercise.

BACKGROUND: Acupressure has been used as an effective way in treating with stomach upset. However the efficacy of acupressure in preventing chemotherapy-induced nausea and vomiting is uncertain. OBJECTIVE: To assess the effectiveness of acupressure on three categories of chemotherapy-induced nausea and vomiting. DATA SOURCES: Databases had been retrieved from inception through February 2016 for the randomized controlled trials in accordance with the inclusion criteria, including PubMed, Cochrane Central Register of Controlled Trials, Web of Science, EMBASE, Science Direct, CINAHL, China Biology Medicine, Chinese National Knowledge infrastructure, Wan Fang and Database for Chinese Technical Periodicals. Additional studies were identified through hand searches of bibliographies and Internet searches. DESIGN: Systematic review with meta-analyses and trial sequential analysis of randomized controlled trials. REVIEW METHODS: Two reviewers selected relevant eligible articles, critical appraisal of the methodological quality was conducted on the basis of using Cochrane Handbook. A standardized Excel form was used to extract information. Meta-analysis and trial sequential analysis was performed using software RevMan 5.3 and TSA 0.9. RESULTS: Twelve studies with 1419 patients were included. Only three studies were assessed as high quality, one study was evaluated as moderate, and eight studies were evaluated as poor. The meta-analysis showed that acupressure reduced the severity of acute (SMD=-0.18, 95% CI -0.31 to -0.05, p<0.01) and delayed (SMD=-0.33, 95% CI -0.64 to -0.01, p=0.04) nausea. However, there was no benefit effect on the incidence or frequency of vomiting. No definitive conclusions were drawn from the trial sequential analysis. CONCLUSION: This systematic review suggested a protective effect of acupressure on chemotherapy-induced nausea and vomiting, while more well-designed clinical trials with larger sample size were needed to draw a definitive conclusion.

The morphologic alterations of pulmonary small vessels measured by computed tomography (CT) have been used to evaluate chronic obstructive pulmonary disease (COPD). However, the relationship between small pulmonary vascular alteration and acute exacerbations of COPD (AECOPD) is not well understood. The aim of this study was to evaluate the cross-sectional area (CSA) of small pulmonary vessel alterations measured on CT images and investigate its relationship with the COPD severity staged by the degree of airflow limitation and the occurrence of AECOPD. We retrospectively reviewed CT scans, clinical characteristics, and pulmonary function test results of 153 patients with COPD. All the patients were divided into AECOPD and non-AECOPD group according to the COPD staging and pulmonary function test results. The percentages of the total CSA less than 5 mm(2) and equal to 5-10 mm(2) over the lung area (%CSA<5 and %CSA5-10, respectively) were measured. The %CSA<5 steadily decreased in relation to the increase of COPD severity. In addition, %CSA<5 of the AECOPD group was significantly lower than that of the non-AECOPD group (0.41±0.13 versus 0.68±0.18, P<0.001), and the optimal cutoff value was 0.56 (sensitivity, 0.863; specificity, 0.731). Therefore, small pulmonary vascular alteration, as measured by %CSA<5, could indicate not only the degree of COPD severity, but also the occurrence of AECOPD.

Computed tomography (CT) is widely used for evaluation of lung diseases. To evaluate the value of CT measurement of pulmonary artery for diagnosis of chronic obstructive pulmonary disease (COPD) and its comorbidity pulmonary hypertension (PH), we retrospectively reviewed the CT of 221 patients with COPD and 115 control patients without cardiovascular or lung disease. Patients with COPD were divided into PH (COPD-PH) and non-PH according to systolic pulmonary artery pressure. Main pulmonary artery (MPA), right pulmonary artery (RPA) and left pulmonary artery branches, and ascending aorta (AAo) and descending aorta (DAo) diameters were measured. Meanwhile, the ratios of MPA/AAo and MPA/DAo were calculated. MPA, RPA, and left pulmonary artery diameters were significantly larger in COPD than those in the controls, and this augment was more obvious in COPD-PH. AAo and DAo diameters did not vary obviously between groups, while MPA/AAo and MAP/DAo increased significantly in COPD and PH. MPA could be helpful for COPD diagnosis (MPA diameter ≥27.5 mm, sensitivity 54%, and specificity 80%), and RPA could be applied for COPD-PH diagnosis (RPA diameter ≥23.4 mm, sensitivity 67%, and specificity 76%). There was a marked correlation between MPA/DAo and systolic pulmonary artery pressure (r=0.594, P<0.001). Therefore, chest CT could be a simple and effective modality for diagnostic evaluation of COPD and its comorbidity, PH.

Pulmonary hypertension (PH) is a common complication of chronic obstructive pulmonary disease (COPD) without effective drugs to treat. We conducted a systematic review and meta-analysis in order to evaluate whether PH specific therapies were effective for stable COPD patients. Data were extracted from PubMed, Cochrane Central Register of Controlled Trials and China Knowledge Resource Integrated Database. Randomized controlled trials (RCTs) with PH specific therapy treated more than 4 weeks in COPD were selected. The main outcome was exercise capacity; meanwhile pulmonary arterial pressure (PAP), hypoxemia and health related life quality were also measured. We included nine trials involving 365 subjects, among which two were treated with bosentan and seven with sildenafil. The study time varied from 4 weeks to 18 months and mostly it was 12 weeks. In a pooled analysis of nine trials, exercise capacity of COPD patients was improved by PH-specific therapy [mean difference (MD) 66.39 m, 95% confidence intervals (CI): 59.44-73.34]. COPD with severe PH (mean PAP >35 mmHg by right heart catheterization or systolic PAP >50 mmHg by echocardiography) improved the exercise capacity (MD 67.24 m, 95% CI: 60.26-74.23), but COPD without PH at rest did not (MD -9.24 m, 95% CI: -75.08 to 56.31). Meanwhile PAP was decreased (MD -9.02 mmHg, 95% CI: -10.71 to -7.34 mmHg). Although hypoxemia and life quality were not improved, the dyspnea was alleviated or at least not aggravated (Borg dyspnea index, MD -0.86, 95% CI: -1.86 to 0.14). In conclusion, PH specific drugs (especially sildenafil) could improve exercise capacity and decrease PAP in COPD patients with severe PH.
