ObjectiveTo determine the ability of cardiopulmonary exercise testing (CPET) to distinguish chronic thromboembolic pulmonary hypertension (CTEPH) from chronic thromboembolic disease (CTED). MethodsFifty patients diagnosed with CTED and fifty-eight patients with CTEPH in the the First Affiliated Hospital of Guangzhou Medical University from April 2019 to February 2022 were retrospectively included. The basic characteristics including age, gender, body mass index, symptom duration, and N-terminal prohormone of brain natriuretic peptide (NTpro-BNP), parameters of arterial blood gas analysis, right heart catheterization, echocardiography, pulmonary function, and CPET were all compared between patients with CTED and those with CTEPH. ResultsPatients with CTEPH displayed longer symptom duration, increased NTpro-BNP, decreased arterial partial pressure of oxygen, larger right atrial and ventricular diameters, and impaired worse resting pulmonary diffusing function compared with those with CTED (P<0.05). However, there was no statistically significant difference in the resting pulmonary ventilation function between the two groups (P>0.05). Among the CPET parameters of the CTEPH group, peak exercise oxygen uptake per kilogram, oxygen uptake at anaerobic threshold, oxygen pulse, oxygen uptake efficiency slope and oxygen saturation were all decreased, while the minute ventilation-carbon dioxide production at anaerobic threshold (VE/VCO2@AT) and VE/VCO2 slope were increased (P<0.05). However, there was no statistically significant difference in heart rate reserve and breathing reserve (P>0.05). Furthermore, VE/VCO2@AT showed high accuracy for distinguishing CTEPH from CTED (sensitivity, 0.825; specificity, 0.860; and the area under the receiver operating characteristic curve 0.897). ConclusionsPatients with CTEPH showed more significant decreased exercise endurance, diffusion dysfunction, and hypoxemia during exercise and insufficient increase in cardiac output compared with CTED patients. Therefore, it is feasible to apply CPET as a new objective examination to distinguish CTED from CTEPH.

ObjectiveTo investigate the effect of 24-week intradialytic progressive resistance exercise on hemoglobin and iron metabolism in maintenance hemodialysis (MHD) patients.MethodsFrom April to May 2019, 62 MHD patients were enrolled and randomly assigned into exercise group (n=31) and control group (n=31). Both groups of patients received regular routine hemodialysis, on that basis, patients in the exercise group completed intradialytic resistance exercise three times per week for 24 weeks. Each exercise included 8-10 muscle groups (grasping the grip ring with both hands, flexion and extension of the elbows and shoulders on the non-vascular side and lower limbs with sandbag), 3 sets of 15 repetitions with a rest of 1-2 min between 2 sets. Exercise began with a low load, the sandbag weight was gradually increased, and the Borg score was aimed to be 11-13 points after exercise. Hemoglobin, serum ferritin, transferrin saturation, serum creatinine, high-sensitivity C-reactive protein, urea clearance index, recombinant human erythropoietin (rHuEPO) dosage at baseline and after 24 weeks, as well as the cumulative iron supplement dose and hemoglobin variation of the two groups during the study period were evaluated.ResultsThere were 20 patients in the exercise group and 30 ones in the control group who completed the study. After 24 weeks of progressive resistance exercise, the medium (lower quartile, upper quartile) of the amount of rHuEPO in the exercise group decreased from 6 000 (6 000, 9 000) U/week to 6 000 (4 500, 7 125) U/week (Z=−2.599, P=0.009), while that in the control group had no statistically significant difference (Z=−1.340, P=0.180); there was no statistically difference in hemoglobin, hemoglobin coefficient of variation, serum ferritin, transferrin saturation, or 24-week cumulative iron supplementation between the two groups.ConclusionIntradialytic progressive resistance exercise can reduce the amount of rHuEPO in MHD patients, which is benefitial to optimizing the management of hemoglobin.
Objective To assess the improvement of different resistance training regimens on blood lipid metabolism and insulin resistance in patients with type 2 diabetes mellitus (T2DM). Methods PubMed, ProQuest, Embase, Web of Science, China National Knowledge Infrastructure, Wanfang, and VIP databases were searched to collect randomized controlled trials of resistance training intervention to improve blood lipids and insulin resistance in patients with T2DM. The search time range was from the establishment of the databases to May 2023. Two reviewers assessed the risk of bias of the included studies using the Physiotherapy Evidence Database scale, and performed a network meta-analysis of the extracted data using Stata 16.0 software. Results In the end, 24 articles were included, and a total of 983 participants were enrolled. The result of network meta-analysis showed that high-frequency and moderate-intensity resistance exercise significantly improved the levels of insulin resistance [standardized mean difference=−1.71, 95% confidence interval (CI) (−2.75, −0.67)], triglycerides [weighted mean difference (WMD)=−0.27 mmol/L, 95%CI (−0.51, −0.04) mmol/L], and total cholesterol [WMD=−0.16 mmol/L, 95%CI (−0.20, −0.12) mmol/L], but had no significant effect on improving the level of high-density lipoprotein [WMD=0.05 mmol/L, 95%CI (−0.02, 0.11) mmol/L] or low-density lipoprotein [WMD=−0.20 mmol/L, 95%CI (−0.42, 0.03) mmol/L]. The results of cumulative probability ranking showed that high-frequency and moderate-intensity resistance exercise was the best in improving insulin resistance, triglycerides, high-density lipoprotein and low-density lipoprotein levels. Conclusion Based on current evidence, high-frequency and moderate-intensity resistance exercise may be the best resistance exercise regimen to improve insulin resistance and lipid metabolism in patients with T2DM.
Objective To systematically analyze the relevant research on the application of preoperative exercise training in the pre-rehabilitation of elderly hip fracture patients, identify the specific content, outcome indicators, and application effects of exercise intervention, in order to provide reference for medical staff to carry out relevant interventions. Methods Computer searches were conducted on domestic and foreign databases such as China National Knowledge Infrastructure, Wanfang Database, China Biomedical Literature Database, VIP, Cochrane Library, PubMed, Embase, Web of Science. The search period was from the establishment of the database to January 2024. The scoping review method was used to screen, summarize, and analyze the included studies. ResultsA total of 10 studies were included, including 3 randomized controlled trial, 1 quasi experimental study, 5 retrospective studies and 1 case report. Preoperative exercise preparation includes completing relevant examinations and providing sufficient pain relief. The types of exercise include adaptive training, resistance training, and aerobic exercise. Monitor the patient’s symptoms, signs, and adverse reactions throughout the exercise process. Outcome measures include physical activity and function, pain, average length of hospital stay, and perioperative complications. Conclusions Preoperative exercise training has a positive effect on elderly patients with hip fracture. Elderly patients with hip fracture should be well prepared for preoperative exercise, based on adaptive training, with resistance exercise as the main focus, while monitoring the patient’s physical signs and adverse events during exercise.
ObjectiveTo systematically review the dose-effect relationship between resistance exercise intervention and lower extremity muscle strength and function enhancement in the aging. MethodsEBSCO, PubMed, Web of Science, CNKI, VIP, and WanFang Data databases were electronically searched to collect randomized controlled trials (RCTs) on the effects of resistance exercise on muscle strength and function of the lower extremities in older adults from inception to July 2022. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. A network meta-analysis was then performed by using RevMan 5.4 and Stata 15.0 software. ResultsA total of 32 RCTs with a total sample size of 1 594 individuals were included. The results of network meta-analysis showed that the elements of resistance exercise prescription: intensity 50%-70% 1RM, period 8-12 weeks, frequency 3-4 times/week, duration 30-45 min, and intervals 1.1-2 min were superior to other doses. ConclusionThe optimal dose of resistance exercise for improving lower extremity muscle strength and function in older adults is moderate exercise intensity (50%-70% 1RM) for 8-12 weeks, 3-4 times per week, 30-45 min per exercise, and 1.1-2 min interval between sets.
Objective To evaluate the clinical significance of operative indication in patients with lung cancer accompanied by lung dysfunction using cardiopulmonary exercise test (CPET). Methods Before operation, using CPET with step program, work rate(W%), maximal oxygen uptake(VO2%P), maximal oxygen uptake per kilogram(VO2/kg) and other indexes were tested in the end of load exercise in 195 patients with lung cancer accompanied by lung dysfunction. Chi-square test and logistic regression analysis were performed for the abnormal rate of indexes mentioned above in patients with or without postoperative respiratory failure. Results After pneumonectomy, W%,VO2%P, VO2/kg, metabolic equivalent (MET), minute ventilation(VE) and respiratory frequency(BF) in patients with postoperative respiratory failure were lower than those in patients with non-postoperative respiratory failure (Plt;0.05 or 0.01). Logistic regression analysis showed that VElt;30 L/min and (BFlt;30) times/min were more related to the morbidity of postoperative respiratory failure than other indexes. As for the patients with lung dysfunction treated by lobectomy, this indexes didn’t show any significant difference between patients with or without postoperative respiratory failure. However, this indexes decreased in patients with postoperative respiratory failure whose ratio of forced expiratory volume in one second to forced vital capacity (FEV1%) were lower than 60%(Plt;0.05 or 0.01). Logistic regression analysis showed that VO2%Plt;60% related to the morbidity of postoperative respiratory failure. Conclusion CPET is useful to evaluate the operative indication in patients with lung cancer accompanied by lung dysfunction. VO2%Plt;60% should be selected as a evaluating index.
Objective To explore the predictive value of cardiopulmonary exercise test (CPET) combined with clinical indexes in the postoperative complications. Methods The clinical data and CPET data (including lung function) of patients undergoing radical esophagectomy in Xuzhou Central Hospital from January 2018 to March 2022 were collected. Univariate analysis and multivariate logistic regression analysis were used to analyze the meaningful evaluation index for the occurrence of postoperative complications. Results A total of 77 patients with esophageal cancer were included, including 59 (76.6%) males and 18 (23.4%) females aged 47-80 years. There were 42 (54.5%) patients in the non-complication group and 35 (45.5%) patients in the complication group. Univariate analysis results showed that the occurrence of postoperative complications was significantly correlated with age, body mass index (BMI), smoking index, tumor stage, the length of postoperative hospital stay, peak work rate (WRpeak), peak kilogram oxygen uptake (VO2peak/kg), the ventilatory equivalent for carbon dioxide slope (VE/VCO2 slope), forced expiratory volume in the first second/forced vital capacity (FEV1/FVC) and maximum expiratory flow rate (MMEF) (P<0.05). The results of multivariate logistic regression analysis showed that BMI [OR=1.35, 95%CI (1.03, 1.77), P=0.031], peakVO2/kg [OR=0.64, 95%CI (0.45, 0.93), P=0.018], oxygen uptake-anaerobic threshold (ATVO2) [OR=0.66, 95%CI (0.44, 0.98), P=0.044] and VE/VCO2 slope [OR=1.49, 95%CI (1.10, 2.02), P=0.011] were the related indexes of complications after radical resection of esophageal cancer. The sensitivity of BMI, VO2peak/kg, ATVO2/kg and VE/VCO2 slope in predicting postoperative complications was 82.10%, and the specificity was 87.44%, 95%CI (0.744, 0.955). Conclusion BMI, VO2peak/kg, ATVO2/kg and VE/VCO2 slope can be used as predictors for postoperative complications of esophageal cancer.
Objective To explore the compliance improvement of rehabilitation exercise for patients after spine surgery. Methods Forty-nine in-patients who underwent spinal surgery between June 1st and July 14th 2016 were selected as the control group and 50 in-patients who underwent spinal surgery between July 15th and August 30th 2016 were selected as the trial group. The control group received conventional nursing for rehabilitation exercise, and the tiral group adopted a series of quality improvement measures for rehabilitation exercise. The compliance of functional exercise, the accuracy of patients’ exercise and the satisfaction with health education of the patients were compared between the two groups. Results The functional exercise compliance in the trial group (complete compliance in 45 cases, partial compliance in 4 cases, non-compliance in 1 case) was higher than that in the control group (complete compliance in 9 cases, partial compliance in 34 cases, non-compliance in 6 cases) with a statistical difference (Z=–6.910, P<0.001). The functional exercise accuracy rate of patients was higher in the trial group [84.00%(168/200)] than that in the control group [53.06% (104/196)] with a statistical difference (χ2=44.060, P<0.001). The patients’ satisfaction with health education in the trial group (4.64±0.49) was higher than that in the control group (4.20±0.89) with a statistical difference (t=3.084, P=0.003). Conclusion The implementation of nursing quality improvement intervention can improve the compliance and accuracy rate of rehabilitation functional exercise of patients undergoing spinal surgery, and improve the satisfaction of patients, which is worth promoting.
Pneumoconiosis is an interstitial lung disease with pulmonary fibrosis as the main pathological change. Patients with pneumoconiosis can increase immunity, delay disease progression, reduce symptoms, and improve lung function through respiratory rehabilitation. With the development of the domestic medical stratification, grading, and referral system between various specialties and the promotion of “internet +” model, remote home respiratory rehabilitation has become an inevitable trend in the full-cycle management of chronic respiratory diseases. By searching Chinese and English literatures, this article summarizes the safety, efficacy and research progress of remote home respiratory rehabilitation for pneumoconiosis. The purpose is to provide ideas for patients with pneumoconiosis to receive home-based remote rehabilitation management.
