Lack of predictive biomarkers, potential toxicities and cost-effectiveness concerns highlight the unmet need for better patient selection.openKhan, Khurum; Rata, Mihaela; Cunningham, David; Koh, Dow-Mu; Tunariu, Nina; Hahne, Jens C; Vlachogiannis, George; Hedayat, Somaieh; Marchetti, Silvia; Lampis, Andrea; Damavandi, Mahnaz Darvish; Lote, Hazel; Rana, Isma; Williams, Anja; Eccles, Suzanne A; Fontana, Elisa; Collins, David; Eltahir, Zakaria; Rao, Sheela; Watkins, David; Starling, Naureen; Thomas, Jan; Kalaitzaki, Eleftheria; Fotiadis, Nicos; Begum, Ruwaida; Bali, Maria; Rugge, Massimo; Temple, Eleanor; Fassan, Matteo; Chau, Ian; Braconi, Chiara; Valeri, NicolaKhan, Khurum; Rata, Mihaela; Cunningham, David; Koh, Dow-Mu; Tunariu, Nina; Hahne, Jens C; Vlachogiannis, George; Hedayat, Somaieh; Marchetti, Silvia; Lampis, Andrea; Damavandi, Mahnaz Darvish; Lote, Hazel; Rana, Isma; Williams, Anja; Eccles, Suzanne A; Fontana, Elisa; Collins, David; Eltahir, Zakaria; Rao, Sheela; Watkins, David; Starling, Naureen; Thomas, Jan; Kalaitzaki, Eleftheria; Fotiadis, Nicos; Begum, Ruwaida; Bali, Maria; Rugge, Massimo; Temple, Eleanor; Fassan, Matteo; Chau, Ian; Braconi, Chiara; Valeri, Nicol

    Introduction to morphological and functional evaluation of the heart and coronary arteries

    Get PDF
    In the last years, the number of clinical indications for the evaluation of the heart – with both computed tomography (CT) and magnetic resonance (MR) – exponentially grew. This evidence reflects the remarkable technological developments of both techniques allowing unprecedented spatial, temporal and contrast resolution levels and to comprehensively evaluate cardiac pathology, combining anatomical information with functional assessment and tissue characterization of myocardial diseases

    Combined burden and functional impact tests for cancer driver discovery using DriverPower

    Get PDF
    The discovery of driver mutations is one of the key motivations for cancer genome sequencing. Here, as part of the ICGC/TCGA Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium, which aggregated whole genome sequencing data from 2658 cancers across 38 tumour types, we describe DriverPower, a software package that uses mutational burden and functional impact evidence to identify driver mutations in coding and non-coding sites within cancer whole genomes. Using a total of 1373 genomic features derived from public sources, DriverPower's background mutation model explains up to 93% of the regional variance in the mutation rate across multiple tumour types. By incorporating functional impact scores, we are able to further increase the accuracy of driver discovery. Testing across a collection of 2583 cancer genomes from the PCAWG project, DriverPower identifies 217 coding and 95 non-coding driver candidates. Comparing to six published methods used by the PCAWG Drivers and Functional Interpretation Working Group, DriverPower has the highest F1 score for both coding and non-coding driver discovery. This demonstrates that DriverPower is an effective framework for computational driver discovery

    Functional language & literacy in practice: a higher education music context

    Get PDF
    Currently most Higher Education (HE) and Vocational Education and Training (VET) courses do not specifically address functional literacy skills. A student could potentially pass the course, yet still be functionally illiterate. This paper is an attempt to consider what language and literacy issues might mean in practice in the context of Australian music higher education through investigating the role of reflective practice in music performance. A graduating music performance class at the Australian Institute of Music is employed as a case study to unpack the role of functional literacy in this context. Here, aligning cognitive processes with course development may avail opportunities for literacy skills to develop, but it still remains a question as to where such opportunities could exist within the broader education field. Regardless, the aim is to support content understanding by focusing on the nature and practices of academic reading and writing in all education environments

    Functional near infrared spectroscopy (fNIRS) to assess cognitive function in infants in rural Africa

    Get PDF
    Cortical mapping of cognitive function during infancy is poorly understood in low-income countries due to the lack of transportable neuroimaging methods. We have successfully piloted functional near infrared spectroscopy (fNIRS) as a neuroimaging tool in rural Gambia. Four-to-eight month old infants watched videos of Gambian adults perform social movements, while haemodynamic responses were recorded using fNIRS. We found distinct regions of the posterior superior temporal and inferior frontal cortex that evidenced either visual-social activation or vocally selective activation (vocal > non-vocal). The patterns of selective cortical activation in Gambian infants replicated those observed within similar aged infants in the UK. These are the first reported data on the measurement of localized functional brain activity in young infants in Africa and demonstrate the potential that fNIRS offers for field-based neuroimaging research of cognitive function in resource-poor rural communities

    Functional capacity and actual daily activity do not contribute to patient satisfaction after total knee arthroplasty

    Abstract Background: After total knee arthroplasty (TKA) only 75-89% of patients are satisfied. Because patient satisfaction is a prime goal of all orthopaedic procedures, optimization of patient satisfaction is of major importance. Factors related to patient satisfaction after TKA have been explored, but no studies have included two potentially relevant factors, i.e. the functional capacity of daily activities and actual daily activity. This present prospective study examines whether functional capacity and actual daily activity (in addition to an extensive set of potential factors) contribute to patient satisfaction six months after TKA. Methods: A total of 44 patients were extensively examined preoperatively and six months post surgery. Functional capacity was measured with three capacity tests, focusing on walking, stair climbing, and chair rising. Actual daily activity was measured in the patient's home situation by means of a 48-hour measurement with an Activity Monitor. To establish which factors were related to patient satisfaction six months post surgery, logistic regression analyses were used to calculate odds ratios. Results: Preoperative and postoperative functional capacity and actual daily activity had no relation with patient satisfaction. Preoperatively, only self-reported mental functioning was positively related to patient satisfaction. Postoperatively, based on multivariate analysis, only fulfilled expectations regarding pain and experienced pain six months post surgery were related to patient satisfaction. Conclusions: Functional capacity and actual daily activity do not contribute to patient satisfaction after TKA. Patients with a better preoperative self-reported mental functioning, and patients who experienced less pain and had fulfilled expectations regarding pain postoperatively, were more often satisfied
