PURPOSE MicroRNAs (miRNAs) post-transcriptionally regulate hundreds of gene targets involved in tumorigenesis thereby controlling vital biological processes, including cellular proliferation, differentiation and apoptosis. MiRNA profiling is an emerging tool for the potential early detection of a variety of malignancies. This study was conducyed to assess(More)
AIM To assess if miRNA expression profiling of bronchoalveolar lavage (BAL) fluid and sputum could be used to detect early-stage non-small cell lung cancer (NSCLC). MATERIALS AND METHODS Hierarchical cluster analysis was performed on the expression levels of 5 miRNAs (miR-21, miR-143, miR-155, miR-210, and miR-372) which were quantified using RNA reverse(More)
Gastric gastrointestinal stromal tumors (GISTs) are the most common sarcoma of the gastrointestinal tract, and surgical resection is the primary treatment of early disease. Limited data exist concerning laparoscopic resections of these neoplasms. This systematic review was designed to evaluate the literature comparing laparoscopic and open surgical(More)
BACKGROUND While advanced age is often associated with poorer surgical outcomes, long-term age-related health status following acute care surgery is unknown. The objective of our study was to assess post-operative cognitive impairment, functional status, and quality of life in elderly patients who underwent emergency surgery. METHODS We identified 159(More)
A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was as follows: In adults with unilateral diaphragmatic paralysis, does diaphragmatic plication offer functional improvement in dyspnoea, better pulmonary function tests (PFTs) and return to activity? A total of 126 papers were found using the(More)
Conversion rates during video-assisted thoracoscopic lobectomy are reported, but no previous publications have classified the cause of conversion. The aim of the study was to develop a quality assessment tool [vascular, anatomy, lymph node, technical (VALT) 'Open'] to evaluate reasons and nature of conversion during the development of a video-assisted(More)
The main objective of this review was to systematically review, assess, and report on the studies that have assessed health related quality of life (HRQOL) after VATS and thoracotomy for resection of lung cancer. We performed a systematic review of six databases. The Downs and Black tool was used to assess the risk of bias. Five studies were included. In(More)
OBJECTIVES To examine health-related quality of life (HRQL) and cognitive and functional status before and after emergency surgical care in elderly adults. DESIGN Six-month prospective cohort study. SETTING Acute care and emergency surgery service at a single, academic tertiary care center, Edmonton, Alberta, Canada. PARTICIPANTS Admitted individuals(More)
BACKGROUND Non-small-cell lung cancer (nsclc) is associated with very poor overall survival because 70% of patients present with locally advanced or metastatic disease at the time of diagnosis. Micrornas (mirnas) are a class of short, noncoding rna molecules whose presence in samples of biologic fluids such as sputum has demonstrated promise as a potential(More)
Background: Surgical resection is the main treatment for early stage lung cancer; the benefits of surgery, however, need to be weighed against possible complications and patients’ quality of life. Methods: We performed a cohort study following patients after video assisted thoracoscopic lobectomy at our tertiary care center. Before surgery, health related(More)
