Prehabilitation Interventions for Cardiac Surgery to Prevent Postoperative Pulmonary Complications: Systematic Review and Meta-Analysis

Background: Postoperative pulmonary complications (PPCs) are associated with a higher risk of morbidity and mortality in patients undergoing cardiac surgery. We aimed to investigate the effect of preoperative interventions on PPCs and length of intensive care unit and hospital stay in patients undergoing cardiac surgery. Methods: A systematic review and meta-analysis was conducted on randomized or quasi-randomized trials by searching PubMed, Medline, ISI Web of Science, Science Direct, Physiotherapy Evidence Database (PEDro), and the Cochrane Library for all available years until December 2023. Our primary outcomes were PPCs including atelectasis and Pneumonia and secondary outcomes were length of intensive care unit and hospital stay. Results: Twenty-one included trials provide data on 2895 participants. The preoperative intervention of inspiratory muscle training (IMT) significantly reduced the PPCs including atelectasis (OR: 0.49, 95%CI: 0.28, 0.86) and Pneumonia (OR: 0.41, 95%CI: 0.25, 0.67) in cardiac patients compared with the control group. Preoperative exercise training intervention is significantly associated with a lower risk (OR: 0.15, 95%CI: 0.06, 0.38) of composite PPCs (i.e. atelectasis and Pneumonia) in the intervention group. Preoperative IMT significantly reduced the postoperative hospital stay by -1.57 days (95% CI: -2.33, -0.81) in the intervention group. Preoperative exercise training significantly decreased the postoperative intensive care unit stay by -2.22 hours (95% CI: -3.05, -1.38) and hospital stay by -1.82 days (95% CI: -3.38, -0.27) in the intervention group. Conclusion: Preoperative intervention of IMT and exercise training significantly reduce PPCs and hospital stay in patients undergoing cardiac surgery.

Head and Neck Cancer and Sarcopenia: An Integrative Clinical and Functional Review

Sarcopenia is recognized as a crucial factor impacting the prognosis, treatment responses, and quality of life of HNC patients. This review discusses various mechanisms, including common etiological factors, such as aging, chronic inflammation, and metabolic dysregulation. Cancer-related factors, including tumor locations and treatment modalities, contribute to the development of sarcopenia. The clinical implications of sarcopenia in HNC patients extend beyond reduced muscle strength; it affects overall mobility, reduces quality of life, and increases the risk of falls and fractures. Sarcopenia serves as an independent predictor of postoperative complications, chemotherapy dose-limiting toxicity, and treatment outcomes, which affect therapy planning and perioperative management decisions. Methods to assess sarcopenia in HNC patients encompass various techniques. A sarcopenia assessment offers a potentially efficient and readily available tool for clinical practice. Interventions and management strategies for sarcopenia involve exercise interventions as a cornerstone; however, challenges arise due to patient-specific limitations during cancer treatment. A routine body composition analysis is proposed as a valuable addition to HNC patient management, with ongoing research required to refine preoperative exercise and nutrition programs for improved treatment outcomes and survival.

Impact of Preoperative Progressive Relaxation Exercises on Postoperative Pain, Comfort, and Recovery

An Updated Systematic Review and Meta-Analysis of Unimodal Prehabilitation with Exercise Intervention to Enhance Postoperative Outcomes in Cancer Surgery.

The objective of this systematic review and meta-analysis was to update the body of evidence on the efficacy of prehabilitation with exercise interventions, in reducing postoperative complications and length of hospital stay after cancer surgery. A comprehensive literature search was conducted on MEDLINE, Embase, The Cochrane Library, CINAHL, AMED, and PsycINFO to identify randomized controlled trials investigating the impact of prehabilitation with exercise interventions for patients undergoing cancer surgery. Primary and secondary outcomes assessed were postoperative complications and length of hospital stay, respectively. Risk of bias was evaluated using the Cochrane risk of bias tool, and Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) methodology was used to determine the strength of evidence. Relative risk and mean difference were calculated using random-effects meta-analysis. In this updated review, 32 trials (n = 2304 participants) were identified, with 5 trials focused on patients undergoing surgery for genitourinary cancer (n = 422 participants), 9 for lower gastrointestinal cancer (n = 639 participants), 6 for upper gastrointestinal cancer (n = 526), and 11 for lung cancer (n = 717 participants). The majority of included trials exhibited some risk of bias. Evidence of low-to-moderate quality indicated that prehabilitation with preoperative exercise significantly reduced postoperative complication rates by approximately 50% and decreased the length of hospital stay by 2.5 days in patients undergoing lung resection. Preoperative exercise did not demonstrate effectiveness in reducing postoperative complications or length of hospital stay for other cancer populations. Evidence supports the efficacy of prehabilitation with exercise in reducing postoperative complications and length of hospital stay in patients undergoing lung cancer surgery. Further research is warranted to establish the efficacy of unimodal prehabilitation with exercise in genitourinary, lower gastrointestinal, and upper gastrointestinal cancer populations having cancer surgery.

Assessment Of the Adherence to Perioperative Nutritional Care Protocols in Brazilian Hospitals: The Preop Week Study

ObjectivesThe study (PreopWeek) aimed to assess the perioperative nutritional care for major surgical patients in Brazilian hospitals, focusing on adherence to emerging multimodal protocols like ERAS and ACERTO. Research Methods & ProceduresAn observational cross-sectional study was conducted in Brazilian hospitals enrolled voluntarily from 19 to 23/06/2023 (convenience sample). Data were collected through patient interviews and medical records review. ResultsData from 219 patients up to the 5th postoperative day or postoperative discharge across 24 hospitals were analyzed. Only three hospitals (12.5%) had established institutional perioperative protocols. Most of the patients were female (60.3%) and over 60 years old (81.7%), submitted to gastrointestinal (34.7%) or orthopedic surgeries (33.3%). General and nutritional preoperative counseling were provided to 82.2% and 62.6% of the patients. Only 25.7% of the patients had preoperative fasting for up to 3 hours, and 28.8% received carbohydrate-rich supplements. Immunonutrition was not received by 43.8% at any moment. Although most started postoperative refeeding within 24 hours (81.7%), 39.4% started with a liquid diet, and 70.6% reported postoperative immobilization in the first 24 hours. Notable differences were observed between hospitals with and without protocols. Hospitals with institutional protocols referred significantly more preoperative exercises and nutritional counseling and higher adherence rates to all the perioperative protocols. ConclusionOur study demonstrates a lack of adherence to the multimodal protocols, even in hospitals with institutional protocols. Future educational programs are necessary to improve this result.

The Role of Preoperative Breathing Exercises in Reducing Postoperative Respiratory Complications in Coronary Artery Bypass Grafting: A Comparative Review of On-Pump and Off-Pump Techniques

Objectives: This review aims to evaluate the efficacy of preoperative breathing exercises in reducing postoperative respiratory complications, particularly respiratory failure, in patients undergoing CABG surgery. The review also compares the outcomes of these interventions in patients undergoing on-pump (ONCAB) versus off-pump (OPCAB) procedures. Methodology: A comprehensive literature search was conducted across multiple databases, including PubMed, Scopus, and Cochrane Library, to identify studies that examined the impact of preoperative breathing exercises on respiratory outcomes in CABG patients. The review focused on randomized controlled trials (RCTs) that compared the effectiveness of these exercises in ONCAB and OPCAB settings. Results: The review identified several studies supporting the role of preoperative breathing exercises in reducing postoperative respiratory complications. These exercises, including diaphragmatic breathing, incentive spirometry, and deep breathing, were associated with improved pulmonary outcomes, such as reduced incidence of respiratory failure, shorter durations of mechanical ventilation, and decreased hospital length of stay. While the overall results were positive for both ONCAB and OPCAB patients, variations were observed based on the surgical technique and patient-specific factors. Conclusion: Preoperative breathing exercises are an effective intervention for reducing the risk of postoperative respiratory complications in CABG patients. The benefits were observed in both ONCAB and OPCAB procedures, with particular advantages noted in the ONCAB group due to the higher baseline risk. Further research is needed to optimize these interventions, considering the individualized nature of patient responses and the specific characteristics of each surgical technique.

Current developments in prehabilitation in urologic oncology.

Prehabilitation describes interventions that are undertaken prior to a major surgical or medical intervention with the objective of improving functional capability with the goal of improving candidacy for therapy, bolstering one's ability to withstand treatment-associated toxicity, functional decline, and facilitating accelerated recovery. The objective of this review is to detail the key tenets of prehabilitation, synthesize contemporary advances in prehabilitation science within Urologic Oncology, and discuss key methodologic trial design considerations salient to future prehabilitation investigations. Contemporary prehabilitation clinical trials have primarily evaluated unimodal interventions aiming to improve functional capacity across the domains of physical exercise, nutrition, and cognition with heightened interest in evaluating multimodal interventions addressing two or more domains. Recent investigations have have demonstrated variable improvements in strength, balance, physical function, and quality of life with preoperative exercise. Although presurgical immunonutrition showed promise in other fields, initial results in uro-oncology have not demonstrated reductions in complications nor improvements in early survival. Emerging data supports the potential of multimodal prehabilitation programs to offer more comprehensive benefits, improving functional outcomes, reducing length of stay, and supporting improved recovery. To date, early prehabilitation studies in patients undergoing surgery for genitourinary malignancies have demonstrated variable ability to facilitate gains in functional capacity and perioperative outcomes. Key issues have arisen including the need to ensure that interventions are pragmatic, scalable, feasible, and acceptable in these populations that often also have a high prevalence of coincident multimorbidity, frailty, and mental health concerns that can increase risk of adverse outcomes after surgery. The integration of personalized prehabilitation strategies as extensions of perioperative enhanced recovery after surgery protocols, supportive care and survivorship paradigms offers of promise to further engage patients in their care, enhance patient resilience and outcomes, while reducing treatment burden in urologic oncology.

The effect of pre-operative exercise training on post-operative cognitive function: a systematic review.

With population aging and advances in surgical and anesthetic procedures, the incidence of surgery in patients over the age of 65 years is increasing. One post-operative complication often encountered by older surgical patients is post-operative cognitive dysfunction (POCD). Preoperative exercise training can improve the overall physiological resilience of older surgical patients, yet its impact on post-operative cognition is less well-established. Six databases (Medline (OVID); EMBASE (OVID); EMCARE (OVID); CINAHL (EBSCOHost), the Cochrane Library, and PubMed) were searched for studies reporting the effect of pre-operative physical training on post-operative cognition. The quality of evidence was assessed using the Mixed Methods Assessment Tool. A total of 3983 studies were initially identified, three of which met the inclusion criteria for this review. Two studies were pilot randomized trials, and one was a prospective randomized trial. Two of the studies were high-quality. Each study used a different type of physical exercise and cognition assessment tool. Across the studies, post-operative cognition (p = 0.005) and attention (p = 0.04) were found to be better in the intervention groups compared to control, with one study reporting no difference between the groups. Preoperative physical training may improve post-operative cognitive function, although more research with a consistent endpoint is required. Future studies should focus on patients at high risk of POCD, such as older adults, and explore the impact of different exercise regimes, including frequency, intensity, time, and type.

Differential response to preoperative exercise training in patients candidates to cardiac valve replacement

BackgroundThere is lack of evidence regarding safety, effectiveness and applicability of prehabilitation on cardiac surgery population, particularly in patients candidates to cardiac valve replacement. The aim of the study is to assess and compare the effect of a multimodal prehabilitation program on functional capacity in patients with severe aortic stenosis (AoS) and severe mitral regurgitation (MR) proposed for valve replacement surgery.MethodsSecondary analysis from a randomised controlled trial whose main objective was to analyze the efficacy of a 4–6 weeks multimodal prehabilitation program in cardiac surgery on reducing postoperative complications. For this secondary analysis, only candidates for valve replacement surgery were selected. The primary outcome was the change in endurance time (ET) from baseline to preoperative assessment measured by a cycling constant work-rate cardiopulmonary exercise test.Results68 patients were included in this secondary analysis, 34 (20 AoS and 14 MR) were allocated to the prehabilitation group and 34 (20 AoS and 14 MR) to control group. At baseline, patients with AoS had better left systolic ventricular function and lower prevalence of atrial fibrillation compared to MR (p = 0.022 and p = 0.035 respectively). After prehabilitation program, patients with MR showed greater improvement in ET than AoS patients (101% vs. 66% increase from baseline). No adverse events related to the prehabilitation program were observed.ConclusionsA 4–6 week exercise training program is safe and overall improves functional capacity in patients with severe AoS and MR. However, exercise response is different according to the cardiac valve type disfunction, and further studies are needed to know the factors that predispose some patients to have better training response.Trial registrationThe study has been registered on the Registry of National Institutes of Health ClinicalTrials.gov (NCT03466606) (05/03/2018).

Impact of Pre- and Post-therapeutic Exercises in Sarcopenia and Pain in Liver Transplant Patients.

Sarcopenia, a state considered by the loss of muscle function and mass, is progressively recognized as a common complication of advanced cirrhosis and is related to negative clinical consequences. Liver transplantation (LT) is one of the options in the treatment of cirrhosis. This study aimed to evaluate the impact of exercise in newly developed (ND) sarcopenia through measurement of the psoas major muscle at the level of the third lumbar vertebra by abdominal computed tomography (CT) images in liver transplant patients. This analytical case-control longitudinal study was conducted on patients aged between 16 and 70 years at King Fahad Specialist Hospital (KFSH-D) in Dammam, Saudi Arabia. The patients were divided into two groups:an intervention group consisting of liver transplant patients (LTx, n=26) and a control group consisting of end-stage liver disease patients (ESLD, n=23) who were not candidates for LT. All participants were treated with a therapeutic exercise program through three phases. The first phase included pre-operative exercises, the second phase included early post-operative exercises, and the last phase included late post-operative exercises. CT scan of the psoas major muscle was performed pre- and post-LT to assess sarcopenia. Pain was measured with a numerical pain scale before and after exercise to evaluate the impact of exercise on pain. Psoas muscle index (PMI) for post-therapeutic exercises in the control and liver transplant groups showed significant differences for both male and female patients compared with the normal range (p<0.05). The liver transplant group showed a significant difference in mean weight loss, body mass index (BMI), and numerical pain rating scale (NPRS) observed on post-therapeutic exercises compared to baseline data. Conclusion: By and large, the finding revealed a substantial impact of therapeutic exercise on patient outcomes in terms of anthropometric characteristics, abdominal pain, handgrip strength (HGS), and PMI. The mean PMI at post-therapeutic exercises showed a significant increase by measuring the psoas major muscle at the level of the third lumbar vertebra by abdominal CT, which may indicate the extent of improvement and recovery from the ND sarcopenia in LTx.The results emphasize the potential advantages of pre- and post-therapeutic exercise in LTx, including enhancements in muscle strength and mass, as well as pain management associated with liver function and general health. Optimizing patient outcomes and promoting a more comprehensive approach to liver disease treatment may be achieved by including exercise activities in pre- and post-LT care procedures.

Effect of home-based prehabilitation on objectively measured physical activity in patients undergoing elective major cardiac and non-cardiac surgery. Data from a randomized controlled trial

Abstract Background Low functional capacity in patients undergoing major elective surgery is associated with postoperative complications. Prehabilitation aims to increase functional capacity by increasing preoperative physical activity. Low functional capacity in patients eligible for major surgery is associated with high age and comorbid burden. In this population, center-based prehabilitation is a barrier for participation. Therefore, we developed a multimodal home-based prehabilitation intervention. Data regarding the effectiveness of a home-based prehabilitation intervention to increase physical activity before surgery is limited. We hypothesize that home-based prehabilitation leads to an increase in physical activity in patients undergoing major cardiac and non-cardiac surgery. Methods We included patients aged over 65 with a proven low functional capacity and/or ventilatory efficiency measured by preoperative cardiopulmonary exercise testing. Patients were randomized to either standard of care or intervention. The intervention group received a home-based prehabilitation intervention 2-4 weeks before surgery. As part of the multimodal intervention, patients were prescribed a walking regimen according to the physical activity guidelines published by the World Health Organization (WHO). Patients were followed-up with weekly telephone calls by a physiotherapist to increase adherence and motivation. All patients were provided a wrist-worn tri-axial accelerometer at the baseline visit. The accelerometer was collected at the ward once the patient entered the hospital for surgery. Physical activity was estimated by calculating the average Euclidean norm minus one (ENMO, milligravity [mg]) per day. Baseline characteristics were tested by Wilcoxon rank-sum test and a linear model for the primary outcome was performed to adjust for confounders. Data analysis was performed using R Studio. Results 37 patients scheduled for cardiac and 62 for non-cardiac surgery were included (Table 1). Mean group difference of daily physical activity levels in non-cardiac surgery patients was 3.01 mg (p = 0.03, 95% CI [0.3, 5.6]). Mean group difference of daily physical activity levels in cardiac surgery patients was 0.27 mg (p = 0.95, 95% CI [-4.1, 5.0]) (Figure 1). Patients undergoing cardiac surgery had higher overall activity levels compared to non-cardiac also when adjusted for age. Conclusion Home-based prehabilitation increases preoperative physical activity levels in patients undergoing major non-cardiac surgery, but not in patients undergoing major cardiac surgery. Higher activity levels in cardiac surgery patients was unexpected, but may be explained by previous inclusion of patients with cardiac diseases in exercise-based rehabilitation and physical activity recommendations at routine cardiac follow-up visits.

Evaluation of the Effect of the Pre-Operative Exercise Training on Weight Loss, Quality of Life, and Cardiopulmonary Parameter in Bariatric Metabolic Surgery: A Systematic Review and Meta-Analysis.

The purpose of this study is to assess the impact of pre-surgery exercise training on cardiopulmonaryfitness. Ten articles (six RCTs and four non-RCTs) involving 281 individuals were finally included in the synthesis. Regarding the effect on VO2 peak, overall standardized mean differences were 0.71 (95% CI, 0.31 to 1.11, n = 103) with heterogeneity (I2 = 0%, P = 0.49). For 6MWT, overall weighted mean differences (distance in meters) were 31.87 (95% CI, 27.84 to 35.89, n = 100) with heterogeneity (I2 = 0%, P = 0.96). Engaging in pre-bariatric metabolic surgery exercise training might improve anthropometric parameters and cardiopulmonary fitness with no significant changes in components of quality of life. However, considering high levels of heterogeneity, the results should be generalized cautiously.

Association between psoas major muscle mass and CPET performance and long-term survival following major colorectal surgery: A retrospective cohort study

ObjectivesTo evaluate whether computed tomography (CT)-derived psoas major muscle measurements could predict preoperative cardiopulmonary exercise testing (CPET) performance and long-term mortality in patients undergoing major colorectal surgery and to compare predictive performance of psoas muscle measurements using 2D approach and 3D approach. MethodsA retrospective cohort study compliant with STROCSS standards was conducted. Consecutive patients undergoing major colorectal surgery between January 2011 and January 2017 following CPET as part of their preoperative assessment were included. Regression analyses were modelled to investigate association between the CT-derived psoas major muscle mass variables [total psoas muscle area (TPMA), total psoas muscle volume (TPMV) and psoas muscle index (PMI)] and CPET performance and mortality (1-year and 5-year). Discriminative performances of the variables were evaluated using Receiver Operating Characteristic (ROC) curve analysis. ResultsA total of 457 eligible patients were included. The median TPMA and TPMV were 21 ​cm2 (IQR: 15–27) and 274 ​cm3 (IQR: 201–362), respectively. The median PMI measured via 2D and 3D approaches were 7 ​cm2/m2 (IQR: 6–9) and 99 ​cm3/m2 (IQR: 76–120), respectively. The risks of 1-year and 5-year mortality were 7.4% and 27.1%, respectively. Regression analyses showed TPMA, TPMV, and PMI can predict preoperative CPET performance and long-term mortality. However, ROC curve analyses showed no significant difference in predictive performance amongst TPMA, TPMV, and PMI. ConclusionRadiologically-measured psoas muscle mass variables may predict preoperative CPET performance and may be helpful with informing more objective selection of patients for preoperative CPET and prehabilitation.

Correlation between preoperative cardiopulmonary exercise testing and six-minute walk test, five-times sit to stand test and Short Form-36 physical component score in patients undergoing cytoreductive surgery

IntroductionAssessment of preoperative function is important for determining fitness for surgery, preoperative optimisation and predicting postoperative morbidity in patients undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC). This study explored correlations between preoperative cardiopulmonary exercise testing (CPET) variables, and six-minute walk test (6MWT), five-times sit to stand test (5STS) and Short Form-36 (SF-36) physical component score in patients scheduled for elective CRS-HIPEC. MethodsThis study included patients who underwent preoperative CPET, 6MWT, 5STS and responded to the SF-36 survey prior to elective CRS-HIPEC at Royal Prince Alfred Hospital in Sydney. CPET was performed using a cycle ergometer and measured peak oxygen uptake (VO2 peak) and anaerobic threshold (AT). The associations between preoperative CPET variables and preoperative 6MWT, 5STS and SF-36 were assessed using correlation test. ResultsA total of 133 patients scheduled for elective CRS-HIPEC were included in this study. The median VO2, AT and VE/VCO2 were 20.3 [6.5] ml/kg/min, 13.1 [4.9] ml/kg/min and 29 [4.5], respectively. The median 6MWT, 5STS and SF-36 physical component score were 525 m, 9.2 s and 50.2, respectively. CPET variables were significantly correlated with 6MWT (VO2 r = 0.51; AT r = 0.35; VE/VCO2 r = −0.25; p < 0.01), 5STS (VO2 r = −0.32; AT r = −0.27; VE/VCO2 r = 0.24; p < 0.01) and SF-36 (VO2 r = 0.42; AT r = 0.38; VE/VCO2 r = −0.23; p < 0.01). Conclusions6MWT, 5STS and SF-36 are at best moderately correlated with CPET variables, which suggests that these tests may serve as adjuncts rather than a replacement to CPET in the clinical setting.

Significance of preoperative exercise oxygen desaturation in lung cancer with interstitial lung disease.

Evaluating the diffusing capacity for carbon monoxide (DLco) is crucial for patients with lung cancer and interstitial lung disease. However, the clinical significance of assessing exercise oxygen desaturation (EOD) remains unclear. We retrospectively analysed 186 consecutive patients with interstitial lung disease who underwent lobectomy for non-small-cell lung cancer. EOD was assessed using the two-flight test (TFT), with TFT positivity defined as ≥5% SpO2 reduction. We investigated the impact of EOD and predicted postoperative (ppo)%DLco on postoperative complications and prognosis. A total of 106 (57%) patients were identified as TFT-positive, and 58 (31%) patients had ppo% DLco < 30%. Pulmonary complications were significantly more prevalent in TFT-positive patients than in TFT-negative patients (52% vs 19%, P < 0.001), and multivariable analysis revealed that TFT-positivity was an independent risk factor (odds ratio 3.46, 95% confidence interval 1.70-7.07, P < 0.001), whereas ppo%DLco was not (P = 0.09). In terms of long-term outcomes, both TFT positivity and ppo%DLco < 30% independently predicted overall survival. We divided the patients into 4 groups based on TFT positivity and ppo%DLco status. TFT-positive patients with ppo%DLco < 30% exhibited the significantly lowest 5-year overall survival among the 4 groups: ppo%DLco ≥ 30% and TFT-negative, 54.2%; ppo%DLco < 30% and TFT-negative, 68.8%; ppo%DLco ≥ 30% and TFT-positive, 38.1%; and ppo%DLco < 30% and TFT-positive, 16.7% (P = 0.001). Incorporating EOD evaluation was useful for predicting postoperative complications and survival outcomes in patients with lung cancer and interstitial lung disease.

Preoperative exercise training decreases complications of minimally invasive lung cancer surgery: A randomized controlled trial

ObjectiveLimited evidence exists regarding the efficacy of preoperative exercise in reducing short-term complications after minimally invasive surgery in patients with non–small cell lung cancer. This study aims to investigate the impact of preoperative exercise on short-term complications after minimally invasive lung resection. MethodsIn this prospective, open-label, randomized (1:1) controlled trial at Xiangya Hospital, China (September 2020 to February 2022), patients were randomly assigned to a preoperative exercise group with 16-day alternate supervised exercise or a control group. The primary outcome assessed was short-term postoperative complications, with a follow-up period of 30 days postsurgery. ResultsA total of 124 patients were recruited (preoperative exercise group n = 62; control n = 62). Finally, 101 patients (preoperative exercise group; n = 51 and control; n = 50) with a median age of 56 years (interquartile range, 50-62 years) completed the study. Compared with the control group, the preoperative exercise group showed fewer postoperative complications (preoperative exercise 3/51 vs control 10/50; odds ratio, 0.17; 95% CI, 0.04-0.86; P = .03) and shorter hospital stays (mean difference, −2; 95% CI, −3 to −1; P = .01). Preoperative exercise significantly improved depression, stress, functional capacity, and quality of life (all P < .05) before surgery. Furthermore, preoperative exercise demonstrated a significantly lower minimum blood pressure during surgery and lower increases in body temperature on day 2 after surgery, neutrophil-to-lymphocyte ratio, and neutrophil count after surgery (all P < .05). Exploratory research on lung tissue RNA sequencing (5 in each group) showed downregulation of the tumor necrosis factor signaling pathway in the preoperative exercise group compared with the control group. ConclusionsPreoperative exercise training decreased short-term postoperative complications in patients with non–small cell lung cancer.

Incidence and risk factors for pulmonary hemorrhage after percutaneous CT-guided pulmonary nodule biopsy: an observational study

To evaluate the current incidence of pulmonary hemorrhage and the potential factors contributing to its increased risk after percutaneous CT-guided pulmonary nodule biopsy and to summarize the technical recommendations for its treatment. In this observational study, patient data were collected from ten medical centers from April 2021 to April 2022. The incidence of pulmonary hemorrhage was as follows: grade 0, 36.1% (214/593); grade 1, 36.8% (218/593); grade 2, 18.9% (112/593); grade 3, 3.5% (21/593); and grade 4, 4.7% (28/593). High-grade hemorrhage (HGH) occurred in 27.2% (161/593) of the patients. The use of preoperative breathing exercises (PBE, p =0.000), semiautomatic cutting needles (SCN, p = 0.004), immediate contrast enhancement (ICE, p =0.021), and the coaxial technique (CoT, p = 0.000) were found to be protective factors for HGH. A greater length of puncture (p =0.021), the presence of hilar nodules (p = 0.001), the presence of intermediate nodules (p = 0.026), a main pulmonary artery diameter (mPAD) larger than 29 mm (p = 0.015), and a small nodule size (p = 0.014) were risk factors for high-grade hemorrhage. The area under the curve (AUC) was 0.783. These findings contribute to a deeper understanding of the risks associated with percutaneous CT-guided pulmonary nodule biopsy and provide valuable insights for developing strategies to minimize pulmonary hemorrhage.
