Background: Extended pleurectomy decortication for complete macroscopic resection for pleural mesothelioma has never been evaluated in a randomised trial. The aim of this study was to compare outcomes after extended pleurectomy decortication plus chemotherapy versus chemotherapy alone.
Methods: MARS 2 was a phase 3, national, multicentre, open-label, parallel two-group, pragmatic, superiority randomised controlled trial conducted in the UK.
Assessing the early use of video-assisted thoracoscopic surgery (VATS) or intrapleural enzyme therapy (IET) in pleural infection requires a phase III randomized controlled trial (RCT). To establish the feasibility of randomization in a surgery-versus-nonsurgery trial as well as the key outcome measures that are important to identify relevant patient-centered outcomes in a subsequent RCT. The MIST-3 (third Multicenter Intrapleural Sepsis Trial) was a prospective multicenter RCT involving eight U.

Healthcare professionals in the UK have had to adapt their practice. In particular, surgeons have faced organisational and technical challenges treating patients who carried higher risks, were more urgent and could not wait for prehabilitation or optimisation before their intervention.

However, no direct comparison data exist to inform clinical decision making in people who appear suitable for both procedures. Our aim was to investigate whether LVRS produces superior health outcomes when compared with BLVR at 12 months.

A Covid-delayed Festschrift was held in his honor on May 20, 2022. The speakers reflected on his myriad contributions to surgery, transplantation, and resident/fellow training, as well as current areas of ongoing research to improve clinical outcomes.

We conducted the largest exploration for parasitoids associated with the fly across Sub-Saharan Africa (Kenya, Namibia, and South Africa) including some of the fly's adjoining regions (Canary Islands, Morocco, Réunion Island and Tunisia). From Sub-Saharan regions, four braconids were collected: Bracon celer, Psytallia humilis, P.

Resection remains the mainstay of curative treatment with often significant waiting times. This study aims to quantify the T-stage progression and growth of non-small cell lung cancers (NSCLCs) between radiological diagnosis and resection, and its impact on disease recurrence and survival.

In this investigation, tests were conducted on a number of mixed wastes from different suppliers being processed at a qualifying MRF to evaluate how effective the Regulations (or MRF Code of Practice (MRF CoP)) were in generating useful, meaningful information. The empirical evidence obtained showed that MRF CoP in its current form has a number of serious flaws which detract from the validity and value of the reported operational data.
View Article and Find Full Text PDFThe operation of qualifying materials recovery facilities (MRFs) in England is governed by the MRF code of practice (MRF CoP), which mandates certain sampling and testing practices for the mixed wastes being processed by the MRF. The results of this testing are required to be reported to the system regulator and are then made publicly available in a register. The MRF CoP is critically examined and certain aspects of the testing methodology are shown to be invalid, resulting in inaccurate information being included in the register.

The first two cases involve thymic carcinoma: the first reviews systemic therapy recommendations for non-resectable recurrence and the second case the optimal treatment recommendations after incomplete resection. The third case discusses treatment recommendations for recurrent thymoma after complete resection.
View Article and Find Full Text PDFObjectives: Venous thromboembolic events can be successfully prevented with chemical and/or mechanical prophylaxis measures, but evidence-based guidelines in thoracic surgery are limited, particularly regarding extended post-discharge prophylaxis. This study attempts to gather an international consensus on best practices to inform the development of such guidelines.
Methods: A series of 3 surveys was distributed to the ESTS/AATS/ISTH (European Society of Thoracic Surgeons, American Association of Thoracic Surgeons, International Society for Thrombosis and Haemostasis) venous thromboembolic events prophylaxis working group starting January 2017.
Objectives: Venous thromboembolic events (VTE) after thoracic surgery (TS) can be prevented with mechanical and chemical prophylaxis. Unlike other surgical specialties, TS lacks evidence-based guidelines. In the process of developing these guidelines, an understanding of the current prophylaxis methods practiced internationally is necessary and is described in this article.
View Article and Find Full Text PDFObjectives: Lung cancer is a leading cause of cancer death and in suitable cases the best chance of cure is offered by surgery. Lung resection is associated with significant postoperative cardiorespiratory morbidity, with dyspnea and reduced functional capacity as dominant features. These changes are poorly associated with deterioration in pulmonary function and a potential role of right ventricular (RV) dysfunction has been hypothesized.

Objectives: Following lung resection, there is a decrease in the functional capacity and quality of life, which is not fully explained by changes in pulmonary function. Previous work demonstrates that B-type natriuretic peptide (BNP) is associated with short- and long-term complications following lung resection, leading to the suggestion that cardiac dysfunction may contribute to functional deterioration. Our aim was to investigate any relationship between BNP and subjective and objective indices of functional deterioration following lung resection surgery.

This may be due to a reduction in T-lymphocyte function, a direct oncogenic effect or the increased impact of environmental carcinogens. There has been shown to be significant increases in non-melanoma skin cancers and post-transplant lympho-proliferative disorders, particularly in those treated with OKT3.

Objectives: To evaluate the efficacy and safety of Zephyr EBVs in patients with heterogeneous emphysema and absence of collateral ventilation.
Aim: We investigated if the serum biomarkers of endothelial glycocalyx layer (EGL) disruption, heparan sulfate proteoglycan (HSPG) and syndecan-1 (SDC1) were elevated following lung resection surgery.
Methods: Plasma samples were collected from 16 patients undergoing lobectomy for primary lung cancer. HSPG and SDC1 were measured at five perioperative timepoints.
Pulmonary metastasectomy has become an established mode of therapy in the management of certain patients with metastatic colorectal cancer. All patients undergoing pulmonary resection for metastatic colorectal cancer between March 2008 and February 2014 were studied. 190 patients were identified.

We sought to determine the test performance of PET-CT for mediastinal lymph node staging of pulmonary carcinoid tumours. We collated data from seven institutions, performing a retrospective search on pathological databases for a consecutive series of patients who underwent thoracic surgery (with lymph nodal dissection) for carcinoid tumours with preoperative PET-CT staging.
