Students who leave pre-registration nurse education having failed to complete remain a concern for higher education institutions. This study identifed factors influencing completion using a retrospective cohort analysis to map student characteristics at entry against Year 3 completion data. The study was set in a nursing faculty in a higher education institution in northern England. Data were collected between 2009 and 2014 with five cohorts of students participating (n = 807). Multinomial logistic regression was used to model the dependent variable Progression Outcome with categories of; completion and non-completion (academic and non-academic reasons)...

The commercial success of tissue engineering products requires efficacy, cost effectiveness, and the possibility of scaleup. Advances in tissue engineering require increased sophistication in the design of biomaterials, often challenging the current manufacturing techniques. Interestingly, several of the properties that are desirable for biomaterial design are embodied in the structure and function of plants. This study demonstrates that decellularized plant tissues can be used as adaptable scaffolds for culture of human cells...

The article by Thornton et al. establishes with data from progestogen trials something we have always feared, i.e. the corruption of reported results through selective publication of outcomes. In their analysis, trials with a predefined primary outcome showed no effect of progesterone consistently; trials that did not report a predefined primary outcome, however, had a tendency to show more promising results. Indeed this problem is so ingrained that even prospective registration of trials has not fully addressed it...

BACKGROUND: Several observational studies have suggested that outdoor air pollution may induce or aggravate asthma. However, epidemiological results are inconclusive due to the presence of numerous moderators which influence this association. The goal of this study was to assess the relationship between outdoor air pollutants and moderate or severe asthma exacerbations in children and adults through a systematic review and multilevel meta-analysis. MATERIAL AND METHODS: We searched studies published in English on PubMed, Scopus, and Google Scholar between January 2000 and October 2016...

The development of clinical trials for Duchenne muscular dystrophy (DMD) in China faces many challenges due to limited information about epidemiological data, natural history and clinical management. To provide these detailed data, we developed a comprehensive database based on registered DMD patients from South China and analysed their clinical and mutational characteristics. The database included DMD registrants confirmed by clinical presentation, family history, genetic detection, prognostic outcome, and/or muscle biopsy...

GroupA streptococci (GAS) cause a wide spectrum of diseases ranging from benign pharyngitis and skin infections to severe invasive disease and the immune sequelae rheumatic fever and rheumatic heart disease. Pharyngitis, one of the most frequent diseases caused by GAS, is highly prevalent in school-age children in temperate climates and a major cause of antibiotic use. An efficacious vaccine would reduce disease burden associated with pharyngitis and the need of care for sick children. Importantly, GAS pharyngitis is recognised as the main precursor for acute rheumatic fever so a vaccine that is efficacious against GAS pharyngitis should also prevent acute rheumatic fever and rheumatic heart disease...

REVIEW
M Prior, R Hibberd, N Asemota, J G Thornton
BACKGROUND: Progestogens have been evaluated in numerous trials and meta-analyses, many of which concluded they were effective. However, two large trials PROMISE and OPPTIMUM have recently concluded that progesterone was ineffective. This raises the possibility that earlier studies and reviews had been biased by either selective publication or selective choice of outcomes, so called "P-hacking". OBJECTIVES: To compare the findings all progestogen trials and systematic reviews with those of trials with pre-registered primary outcomes which avoided selective outcome reporting...

The PET and CT fusion image, combining the anatomical and functional information, has important clinical meaning. An effective registration of PET and CT images is the basis of image fusion. This paper presents a multithread registration method based on contour point cloud for 3D whole-body PET and CT images. Firstly, a geometric feature-based segmentation (GFS) method and a dynamic threshold denoising (DTD) method are creatively proposed to preprocess CT and PET images, respectively. Next, a new automated trunk slices extraction method is presented for extracting feature point clouds...

In total hip arthroplasty (THA), the accurate positioning of implants is the key to achieve a good clinical outcome. Computer-assisted orthopaedic surgery (CAOS) has been developed for more accurate positioning of implants during the THA. There are passive, semi-active, and active systems in CAOS for THA. Navigation is a passive system that only provides information and guidance to the surgeon. There are 3 types of navigation: imageless navigation, computed tomography (CT)-based navigation, and fluoroscopy-based navigation...

PURPOSE: Epidural and spinal needle insertions, as well as facet joint denervation and injections are widely performed procedures on the lumbar spine for delivering anesthesia and analgesia. Ultrasound (US)-based approaches have gained popularity for accurate needle placement, as they use a non-ionizing, inexpensive and accessible modality for guiding these procedures. However, due to the inherent difficulties in interpreting spinal US, they yet to become the clinical standard-of-care...

Understanding regional deformation in the lung has long attracted the medical community, as parenchymal deformation plays a key role in respiratory physiology. Recent advances in image registration make it possible to noninvasively study regional deformation, showing that volumetric deformation in healthy lungs follows complex spatial patterns not necessarily shared by all subjects, and that deformation can be highly anisotropic. In this work, we systematically study the regional deformation in the lungs of eleven human subjects by means of in vivo image-based biomechanical analysis...

BACKGROUND: Remote ischemic postconditioning (RIPC) is suggested to protect the myocardium against ischemia in various settings. However, the effect of RIPC in patients with acute ST-elevation myocardial infarction (STEMI) who undergo thrombolysis has yet to be examined. PATIENTS AND METHODS: In this single-center, randomized controlled trial, we examined the effect of RIPC on the resolution of ST-segment elevation (STR) in response to thrombolysis. Patients in the RIPC group had three cycles of 5‑min cuff inflation followed by 5‑min deflation to the upper arm...
