Abstract
INTRODUCTION Cardiac rehabilitation (CR) delivered by rehabilitation specialists in a healthcare setting is effective in improving functional capacity and reducing readmission rates after cardiac surgery. It is also associated with a reduction in cardiac mortality and recurrent myocardial infarction. This trial assesses the feasibility of a home-based CR programme delivered using a mobile application (app). METHODS The Rehabilitation through Exercise prescription for Cardiac patients using an Artificial intelligence web-based Programme (RECAP) randomised controlled feasibility trial is a single-centre prospective study, in which patients will be allocated on a 1:1 ratio to a home-based CR programme delivered using a mobile app with accelerometers or standard hospital-based rehabilitation classes. The home-based CR programme will employ artificial intelligence to prescribe exercise goals to the participants on a weekly basis. The trial will recruit 70 patients in total. The primary objectives are to evaluate participant recruitment and dropout rates, assess the feasibility of randomisation, determine acceptability to participants and staff, assess the rates of potential outcome measures and determine hospital resource allocation to inform the design of a larger randomised controlled trial for clinical efficacy and health economic evaluation. Secondary objectives include evaluation of health-related quality of life and 6 minute walk distance. ETHICS AND DISSEMINATION RECAP trial received a favourable outcome from the Berkshire research ethics committee in September 2022 (IRAS 315483).Trial results will be made available through publication in peer-reviewed journals and presented at relevant scientific meetings. TRIAL REGISTRATION NUMBER ISRCTN97352737.

Abstract
Background Traumatic tracheal rupture is a severe closed chest injury that often causes major respiratory and circulatory disturbances requiring emergency surgery. We have found that veno-venous extracorporeal membrane oxygenation (VV-ECMO) employs lung-protective ventilation strategies to facilitate lung rest, aiming to minimize the risk of ventilator-induced lung injury, while ensuring adequate oxygenation. Case Description We presented 3 critically ill patients who presented with traumatic bronchial rupture between 2019 and 2021, and underwent emergency thoracic surgery with the help of VV-ECMO. The ECMO support time, the operative time, the duration of postoperative hospital stay, and the postoperative mechanical ventilation time were collected in this study. All patients were successfully treated and discharged home. The duration of surgery ranged from 135 to 180 min, the duration of ECMO use ranged from 98 to 123 h, the duration of postoperative ventilator use ranged from 5 to 8 days, and the duration of postoperative hospital stay ranged from 14 to 30 days. All 3 patients had good postoperative pulmonary re-expansion, with no residual tracheal or bronchial stenosis, and good physical activity following the surgery. Conclusions We reported successful use of VV-ECMO in critically ill patients with traumatic bronchial rupture presenting in acute respiratory and circulatory failure. Performing emergency surgery with ECMO-assisted support can provide more time to stabilize the patient and ensure the safety of the procedure. However, considering the small sample size of this study, larger cohorts with long-term follow-up data are needed to further evaluate its application.

Abstract
Background The detection of pulmonary nodules significantly impacts the lives and mental health of patients. Although the 2020 National Comprehensive Cancer Network (NCCN) guidelines recommend scheduled surveillance for nodules ≤8 mm, patients often opt to have their nodules surgically removed. Methods A cross-sectional questionnaire was administered to patients with small pulmonary nodules who presented to a local grade 3 hospital with small pulmonary nodules and decided to receive surgery versus prescribed monitoring. The questionnaire included four aspects: (I) patient characteristics; (II) nodule-specific knowledge; (III) doctor-patient communication; and (IV) nodular-specific distress. Nodular-specific distress was measured by the Impact of Event Scale-Revised (IES-R). Results A total of 234 (69%) patients responded to the survey and were included in the final analysis. Poor performance in activities of daily living (ADLs), the presence of solid nodules, multifocal disease, and a family history of lung cancer were significantly associated with reported anxiety. Most notably, facilitating patient choice for surgery was the computed tomography (CT) scan results, with reference to lung nodule size and number of nodules, where concerns related to lung nodule, cancer risk, and fear of surgery or death had a significant psychological impact on patients. Conclusions In this cohort of patients who elected to have their small pulmonary nodules surgically removed, we identified key factors underlying their anxiety toward guideline recommended surveillance. Our findings will be useful for clinicians when discussing treatment options with their patients.

Abstract
BACKGROUND The nature of the solid component of subsolid nodules (SSNs) can indicate tumor pathological invasiveness. However, preoperative solid component assessment still lacks a reference standard. METHODS In this retrospective study, an AI algorithm was proposed for measuring the solid components ratio in SSNs, which was used to assess the diameter ratio (1D), area ratio (2D), and volume ratio (3D). The radiologist measured each SSN's consolidation to tumor ratio (CTR) twice, four weeks apart. The area under the receiver-operating characteristic (ROC) curve (AUC) was calculated for each method used to discriminate an Invasive Adenocarcinoma (IA) from a non-IA. The AUC and the time cost of each measurement were compared. Furthermore, we examined the consistency of measurements made by the radiologist on two separate occasions. RESULTS A total of 379 patients (the primary dataset n = 278, the validation dataset n = 101) were included. In the primary dataset, compared to the manual approach (AUC: 0.697), the AI algorithm (AUC: 0.811) had better predictive performance (P =.0027) in measuring solid components ratio in 3D. Algorithm measurement in 3D had an AUC no inferior to 1D (AUC: 0.806) and 2D (AUC: 0.796). In the validation dataset, the AI 3D method also achieved superior diagnostic performance compared to the radiologist (AUC: 0.803 vs 0.682, P =.046). The two measurements of the CTR in the primary dataset, taken 4 weeks apart, have 7.9 % cases in poor consistency. The measurement time cost by the radiologist is about 60 times that of the AI algorithm (P <.001). CONCLUSION The 3D measurement of solid components using AI, is an effective and objective approach to predict the pathological invasiveness of SSNs. It can be a preoperative interpretable indicator of pathological invasiveness in patients with lung adenocarcinoma.

Abstract
The purpose of this study was to understand the views and experiences of patients enrolled and staff involved in the prehabilitation of elective patients undergoing cardiac surgery trial. This sub-study was informed by normalisation process theory, a framework for evaluating complex interventions, and used consecutive sampling to recruit patients assigned to both the intervention and control groups. Patients and all staff involved in delivering the trial were invited to participate in focus groups, which were recorded, transcribed verbatim and subjected to reflexive thematic analysis. Five focus groups were held comprising 24 participants in total (nine patients assigned to the prehabilitation; seven assigned to control; and eight staff). Five themes were identified. First, preparedness for surgery reduced fear, where participants described that knowing what to expect from surgery and preparing the body physically increased feelings of control and subsequently reduced apprehension regarding surgery. Second, staff were concerned but trusted in a safe environment, describing how, despite staff's concerns regarding the risks of exercise in this population, the patients felt safe in their care whilst participating in an exercise programme in hospital. Third, rushing for recovery and the curious carer, where patients from both groups wanted to mobilise quickly postoperatively whilst staff visited patients on the ward to observe their recovery progress. Fourth, to survive and thrive postoperatively, reflecting staff and patients' expectations from the trial and what motivated them to participate. Fifth, benefits are diluted by lengthy waiting periods, reflecting the frustration felt by patients waiting for their surgery after completing the intervention and the fear about continuing exercise at home before they had been 'fixed'. To conclude, functional exercise capacity may not have improved following prehabilitation in people before elective cardiac surgery due to concerns regarding the safety of exercise that may have hindered delivery and receipt of the intervention. Instead, numerous non-physical benefits were elicited. The information from this qualitative study offers valuable recommendations regarding refining a prehabilitation intervention and conducting a subsequent trial.

Abstract
Whether thymectomy (TM) or thymomectomy (TMM) is better for non-myasthenic patients with early-stage thymoma. We conducted a meta-analysis to compare the clinical outcomes and prognoses of non-myasthenic patients with early-stage thymoma treated using thymectomy versus thymomectomy. PubMed, Embase, Cochrane Library and CNKI databases were systematically searched for relevant studies on the surgical treatment (TM and TMM) of non-myasthenic patients with early-stage thymoma published before March 2022. The Newcastle-Ottawa scale was used to evaluate the quality of the studies, and the data were analyzed using RevMan version 5.30. Fixed or random effect models were used for the meta-analysis depending on heterogeneity. Subgroup analyses were performed to compare short-term perioperative and long-term tumor outcomes. A total of 15 eligible studies, including 3023 patients, were identified in the electronic databases. Our analysis indicated that TMM patients might benefit from a shorter duration of surgery (p = 0.006), lower blood loss volume (p < 0.001), less postoperative drainage (p = 0.03), and a shorter hospital stay (p = 0.009). There were no significant differences in the overall survival rate (p = 0.47) or disease-free survival rate (p = 0.66) between the two surgery treatment groups. Likewise, TM and TMM were similar in the administration of adjuvant therapy (p = 0.29), resection completeness (p = 0.38), and postoperative thymoma recurrence (p = 0.99). Our study revealed that TMM might be a more appropriate option in treating non-myasthenic patients with early-stage thymoma.

Abstract
BACKGROUND Esophageal cancer (EC) is the seventh most common cancer in the world, with 604,000 new cases diagnosed each year. Immune checkpoint inhibitors (ICIs) including programmed death ligand-1 (PD-L1) inhibitors have demonstrated a considerable survival advantage over chemotherapy in numerous randomized controlled trials (RCTs), particularly in patients with advanced esophageal squamous cell carcinoma (ESCC). In this analysis, we aimed to demonstrate that ICIs are more safe and effective than chemotherapy when used as a second-line treatment for advanced ESCC. METHODS Publications on the safety and efficiency of ICIs in advanced ESCC that were available prior to February 2022 were searched in the Cochrane Library, Embase, and PubMed databases. Studies with missing data were eliminated, and studies that compared the treatments between the immunotherapy group and chemotherapy group were included. Statistical analysis was carried out using RevMan 5.3, and risk and quality were evaluated with relevant evaluation tools. RESULTS Five studies met the inclusion criteria were selected, involving 1,970 patients with advanced ESCC. We compared chemotherapy and immunotherapy in the second-line treatment of advanced ESCC. ICIs considerably enhanced both the objective response rate (P=0.007) and overall survival (OS; P=0.001). However, the effect of ICIs on progression-free survival (PFS) was not significant (P=0.43). ICIs presented fewer grade 3-5 treatment-related adverse events (TRAEs), and there was also a suggested linkage between both PD-L1 expression and the effectiveness of the therapeutic intervention. CONCLUSIONS For patients with advanced ESCC, ICIs are more effective and safer than chemotherapy, and thus have a higher treatment value.

Abstract
OBJECTIVES The prognosis of patients with locally advanced esophageal squamous cell carcinoma with different recurrence backgrounds is highly heterogeneous. This study aims to explore the effects of recurrence patterns on prognosis. METHODS The phase III, multicenter, prospective NEOCRTEC5010 trial enrolled 451 patients with stage IIB-III esophageal squamous cell carcinoma randomly assigned to neoadjuvant chemoradiotherapy combined with surgery (NCRT group) or surgery alone (S group) and followed them long-term. We investigated the effects of recurrence patterns on survival in patients undergoing radical esophagectomy. RESULTS In total, 353 patients were included in the study. The 5-year overall survival of patients with different recurrence patterns was significantly different: recurrence versus recurrence-free (17.8% vs 89.2%; P < .001), early recurrence versus late recurrence (4.6% vs 51.2%; P < .001), and distant metastasis versus locoregional recurrence (17.0% vs 20.0%; P = .666). Patients with early recurrence had significantly shorter survival after recurrence than those with late recurrence (hazard ratio, 1.541; 95% confidence interval, 1.047-2.268, P = .028). There was no significant difference in postrecurrence survival between patients with distant metastasis and locoregional recurrence (hazard ratio, 1.181; 95% confidence interval, 0.804-1.734; P = .396). Multivariate logistic analysis showed that pN1 stage, lymph node dissection <20, and lack of response to NCRT were independent risk factors for postoperative early recurrence. Multivariate Cox regression suggested that NCRT, age ≥60 years, early recurrence, and the pN1 stage were independent risk factors for shortened survival after recurrence. CONCLUSIONS Prerecurrence primary tumor stage is inaccurate in predicting postrecurrence survival. In contrast, recurrence patterns can guide follow-up while also predicting postrecurrence survival. NCRT prolongs disease-free survival but is associated with a worse prognosis in patients with recurrence, especially early recurrence.

Abstract
INTRODUCTION Prehabilitation prior to surgery has been shown to reduce postoperative complications, reduce length of hospital stay and improve quality of life after cancer and limb reconstruction surgery. However, there are minimal data on the impact of prehabilitation in patients undergoing cardiac surgery, despite the fact these patients are generally older and have more comorbidities and frailty. This trial will assess the feasibility and impact of a prehabilitation intervention consisting of exercise and inspiratory muscle training on preoperative functional exercise capacity in adult patients awaiting elective cardiac surgery, and determine any impact on clinical outcomes after surgery. METHODS AND ANALYSIS PrEPS is a randomised controlled single-centre trial recruiting 180 participants undergoing elective cardiac surgery. Participants will be randomised in a 1:1 ratio to standard presurgical care or standard care plus a prehabilitation intervention. The primary outcome will be change in functional exercise capacity measured as change in the 6 min walk test distance from baseline. Secondary outcomes will evaluate the impact of prehabilitation on preoperative and postoperative outcomes including; respiratory function, health-related quality of life, anxiety and depression, frailty, and postoperative complications and resource use. This trial will evaluate if a prehabilitation intervention can improve preoperative physical function, inspiratory muscle function, frailty and quality of life prior to surgery in elective patients awaiting cardiac surgery, and impact postoperative outcomes. ETHICS AND DISSEMINATION A favourable opinion was given by the Sheffield Research Ethics Committee in 2019. Trial findings will be disseminated to patients, clinicians, commissioning groups and through peer-reviewed publication. TRIAL REGISTRATION NUMBER ISRCTN13860094.

Abstract
Abstract
Introduction
An aortic dissection occurs when there is a tear in the intimal and medial layer of the aorta, leading to a false lumen within the media. Type B aortic dissections (TBAD), according to the Stanford Classification are where the entry tear is located distally from the left subclavian artery. Resolution of a Type B aortic dissection (TBAD) by medical therapy is a very rare event.
Case Presentation
58-year-old gentleman presented with sudden onset central chest pain. A CTPA was organised following a high d-dimer. This showed a TBAD extending from the origin of the left subclavian artery to the level of the diaphragm. His blood pressure was aggressively controlled with IV labetalol and IV isosorbide dinitrate and was monitored for 2 weeks. He was then discharged home on oral antihypertensive medication. A follow up CT aortogram was done 7 months later which showed that the false lumen of the TBAD has improved from 18mm to 2 mm.
Discussion
The anti-inotropic effect of beta blockers reduces the stress on the aortic wall and therefore prevents further dilatation. Aggressive control of blood pressure and heart rate comes with its own disadvantages. It had been shown, patients managed conservatively were more likely to develop renal failure (43%) compared to those having endovascular repair. About half of those patients required surgical treatment. There are not many cases in literature where a TBAD had resolved with medication.
Conclusions
As evident from this case, rigorous management of blood pressure may help with cases of Type B Dissection.
