OBJECTIVES: The video-assisted thoracoscopic surgery (VATS) approach has become a standard for the treatment of early-stage non-small-cell lung cancer (NSCLC). Recently published meta-analyses proved the benefit of VATS versus thoracotomy for overall survival (OS) and reduction of postoperative complications. The aim of this study was to compare early outcomes, long-term survival and rate of postoperative complications of the VATS approach versus thoracotomy. METHODS: In this retrospective cohort study, we analysed 982 individuals who underwent surgical resection for Stage I-IIA NSCLC between 2007 and 2015...

The National Health Service (UK) offers initial screening appointments for children referred to child and adolescent mental health services to determine clinical need and assess risk. Conversation analysis was utilized on 28 video recordings of these assessments, lasting approximately 90 minutes each with a multidisciplinary team. This article focuses on the agenda setting strategies used to establish relevant goals with children and adolescents; specifically, the technique of offering 'three wishes'. For example, ' if you had three wishes, what would you like to make happen?' In cases where children initially volunteered an assessment-relevant wish, they tended not to articulate further wishes...

Transparency in science is increasingly a hot topic. Scientists are required to show not only results but also evidence of how they have achieved these results. In experimental studies of spinal cord injury, there are a number of standardized tests, such as the Basso-Beattie-Bresnahan locomotor rating scale for rats and Basso Mouse Scale for mice, which researchers use to study the pathophysiology of spinal cord injury and to evaluate the effects of experimental therapies. Although the standardized data from the Basso-Beattie-Bresnahan locomotor rating scale and the Basso Mouse Scale are particularly suited for storage and sharing in databases, systems of data acquisition and repositories are still lacking...

Background/Objective: Evaluating hamstring strength by isokinetic dynamometry is limited by various practical issues such as time and cost. A video-based Nordic hamstring exercise is introduced as an alternative option. The aims of this study are to evaluate 1.) the between-session reliability and 2.) concurrent validity of the testing method compared to a standardized isokinetic dynamometry. Methods: Thirty male elite footballers were recruited for the study. From the Nordic hamstring exercise, the video-analysis-determined Nordic break-point angles where the participant could no longer withstand the force of the fall (eccentric mode) and the number of seconds that the player could hold at 30° forward flexion angle (isometric mode) were measured...

BACKGROUND: In juvenile myoclonic epilepsy, data are limited on the genetic basis of networks promoting convulsions with diffuse polyspikes on electroencephalography (EEG) and the subtle microscopic brain dysplasia called microdysgenesis. METHODS: Using Sanger sequencing, we sequenced the exomes of six members of a large family affected with juvenile myoclonic epilepsy and confirmed cosegregation in all 37 family members. We screened an additional 310 patients with this disorder for variants on DNA melting-curve analysis and targeted real-time DNA sequencing of the gene encoding intestinal-cell kinase ( ICK)...

Whether the robot-assisted minimally invasive esophagectomy (RAMIE) has any advantages over the video-assisted minimally invasive esophagectomy (VAMIE) remains controversial. In this study, we tried to compare the short-term outcomes of RAMIE with that of VAMIE in treating middle thoracic esophageal cancer from a single medical center. Consecutive patients undergoing RAMIE or VAMIE for middle thoracic esophageal cancer from April 2016 to April 2017 were prospectively included for analysis. Baseline data and pathological findings as well as short-term outcomes of these two group (RAMIE group and VAMIE group) patients were collected and compared...

High-speed video analysis has enabled the interaction between a pair of millimetre-sized air bubbles to be studied in aqueous solution. The bubbles were grown in the presence of either poly(glycerol monomethacrylate)-poly(benzyl methacrylate) (PGMA-PBzMA) diblock copolymer spheres or poly(glycerol monomethacrylate)-poly(2-hydroxypropyl methacrylate)-poly(benzyl methacrylate) (PGMA-PHPMA-PBzMA) triblock copolymer worms prepared by polymerisation-induced self-assembly (PISA). A reduction in interfacial tension relative to air bubbles grown in the absence of nanoparticles indicated the adsorption of nanoparticles at the air-water interface...

BACKGROUND: Self-injurious behaviour (SIB) is a treatment-resistant aberrant behaviour that significantly impacts the lives of people with intellectual disabilities (ID). Direct observations of SIB under naturally occurring conditions can inform the unique structural properties of these behaviours, and the contexts in which they occur. While previous applications of sequential analyses have identified strong temporal associations between instances of SIB, they have relied on methods that do not adequately control for chance sequencing and may mask within-participant variability by pooling data across contexts and response topographies...

BACKGROUND: Colonic diverticulosis is one of the most common gastroenterological disorders. Although diverticulosis is typically benign, many individuals develop diverticulitis or other aspects of diverticular disease. Diverticulosis is thought to stem from a complex interaction of environmental, dietary, and genetic factors; however, the contributing genetic factors remain unknown. OBJECTIVE: The aim of our present study was to determine the role of genetic variants within genes encoding for collagens of the connective tissue in diverticulosis...

CHD2 gene has been described in association with different types of childhood myoclonic epilepsy and is emerging as a gene involved in photosensitivity alone or combined with epilepsy. Recent studies suggest that CHD2 could be responsible for a proper phenotype characterized by infantile-onset generalized epilepsy, intellectual disability, and photosensitivity and in particular with self-induced seizures. We report the case of a child with CHD2 mutation and mild developmental impairment that since the age of 3 years started with myoclonic seizures apparently well responding to antiepileptic drugs and that subsequently developed intractable self-induced seizures...
