    Low back pain is one of the most common health issues worldwide, and non-specific low back pain (NLBP), whose causes are unknown, represents 85% of these cases. Hamstring Extension in Bipedal Position (PEBI) is a clinical sign designed to discriminate the cause of the pain of NLBP as of muscular origin due to the stiffness of the hamstring. Currently, PEBI lacks quantitative assessment, which is required to be utilized in primary care. To support the process of getting such information, in this work, we present ASPEBI, a customized MATLAB® app developed to provide researchers and clinicians with a tool for the visualization of the kinematic and spatiotemporal gait parameters of patients examined with PEBI. This objective information is processed from data collected with the Xsens MTw Awinda system, which can be analyzed by the final users. Lastly, this tool is user-friendly with a modular design that allows integration of other physiological technologies to conduct multimodal analysis, and it could be utilized to explore issues related to older populations or populations with neurodegenerative diseases, among others

    Las competiciones de programación son un estímulo importante para los alumnos de informática. Durante los últimos años ha crecido el número de estas competiciones en su mayoría promovidas por grandes empresas con el propósito de reclutar alumnos brillantes. La International Collegiate Programming Contest es la más antigua de ellas, promovida por la ACM y patrocinada por IBM. A la final mundial van los mejores equipos de cada una de las más de 90 competiciones regionales que tienen lugar por todo el mundo. La regional en la que pueden participar las universidades españolas es la Southwestern Europe Regional Contest (España, Italia, Portugal, Suiza, Francia y Austria). Esta regional fue organizada por la Escola Tècnica Superior d’Enginyeria Informàtica de la Universitat Politècnica de València en su edición de 2012 y lo será también en 2013. En este trabajo se presenta la experiencia de planificación de una regional, tanto a nivel organizativo como de planteamiento de los problemas para la competición. Asimismo, se destaca la importancia de este tipo de competiciones en cuanto al desarrollo de habilidades y destrezas en los alumnos, pues su dedicación a solucionar distintos tipos de problemas, combinando conocimientos de matemáticas con técnicas algorítmicas, les da una formación adicional que saben apreciar las grandes empresas. Algunos alumnos de la ETSInf que han participado en estas competiciones están en proceso o ya han sido contratados por empresas del sector como es Google.SUMMARY -- Programming contests are a good stimulus for computer engineering students. These contests have experienced an expansion during last years thanks to the interest of big companies for hiring brilliant students. The International Collegiate Programming Contest is the oldest one, promoted by ACM and sponsored by IBM. The ACM-ICPC World Final takes place every year, only the best teams can participate, which are selected from the ones who compete in the more than 90 regional contests celebrated around the world. Spanish universities can participate in the Southwestern Europe Regional Contest (Spain, Italy, Portugal, France and Austria). The 2012 edition of this regional contest took place in Valencia, organised by the School of Computer Engineering at the Universitat Politècnica de València. The 2013 edition will be organised in Valencia as well. In this paper it is presented the experience of planning a regional contest, both from the point of view of organisation as from posing the problems. Additionally, it is pointed out the value of this sort of programming contests as they foster the development of some abilities and skills in students, because the time they spend solving problems where the knowledge of mathematical concepts and of algorithmic techniques is very important. This fact gives students a special training very appreciated by big software companies. Some former students from ETSInf who participated in international programming contests were hired or are in process of being hired by Google

    Get PDF
    Background: There are no specific recommendations regarding the optimal management of this group of patients. The World Society of Emergency Surgery suggested a nonoperative strategy with antibiotic therapy, but this was a weak recommendation. This study aims to identify the optimal management of patients with acute diverticulitis (AD) presenting with pericolic free air with or without pericolic fluid. Methods: A multicenter, prospective, international study of patients diagnosed with AD and pericolic-free air with or without pericolic free fluid at a computed tomography (CT) scan between May 2020 and June 2021 was included. Patients were excluded if they had intra-abdominal distant free air, an abscess, generalized peritonitis, or less than a 1-year follow-up. The primary outcome was the rate of failure of nonoperative management within the index admission. Secondary outcomes included the rate of failure of nonoperative management within the first year and risk factors for failure. Results: A total of 810 patients were recruited across 69 European and South American centers; 744 patients (92%) were treated nonoperatively, and 66 (8%) underwent immediate surgery. Baseline characteristics were similar between groups. Hinchey II-IV on diagnostic imaging was the only independent risk factor for surgical intervention during index admission (odds ratios: 12.5, 95% CI: 2.4-64, P =0.003). Among patients treated nonoperatively, at index admission, 697 (94%) patients were discharged without any complications, 35 (4.7%) required emergency surgery, and 12 (1.6%) percutaneous drainage. Free pericolic fluid on CT scan was associated with a higher risk of failure of nonoperative management (odds ratios: 4.9, 95% CI: 1.2-19.9, P =0.023), with 88% of success compared to 96% without free fluid ( P <0.001). The rate of treatment failure with nonoperative management during the first year of follow-up was 16.5%. Conclusion: Patients with AD presenting with pericolic free gas can be successfully managed nonoperatively in the vast majority of cases. Patients with both free pericolic gas and free pericolic fluid on a CT scan are at a higher risk of failing nonoperative management and require closer observation

    Evolving trends in the management of acute appendicitis during COVID-19 waves. The ACIE appy II study

    Get PDF
    Background: In 2020, ACIE Appy study showed that COVID-19 pandemic heavily affected the management of patients with acute appendicitis (AA) worldwide, with an increased rate of non-operative management (NOM) strategies and a trend toward open surgery due to concern of virus transmission by laparoscopy and controversial recommendations on this issue. The aim of this study was to survey again the same group of surgeons to assess if any difference in management attitudes of AA had occurred in the later stages of the outbreak. Methods: From August 15 to September 30, 2021, an online questionnaire was sent to all 709 participants of the ACIE Appy study. The questionnaire included questions on personal protective equipment (PPE), local policies and screening for SARS-CoV-2 infection, NOM, surgical approach and disease presentations in 2021. The results were compared with the results from the previous study. Results: A total of 476 answers were collected (response rate 67.1%). Screening policies were significatively improved with most patients screened regardless of symptoms (89.5% vs. 37.4%) with PCR and antigenic test as the preferred test (74.1% vs. 26.3%). More patients tested positive before surgery and commercial systems were the preferred ones to filter smoke plumes during laparoscopy. Laparoscopic appendicectomy was the first option in the treatment of AA, with a declined use of NOM. Conclusion: Management of AA has improved in the last waves of pandemic. Increased evidence regarding SARS-COV-2 infection along with a timely healthcare systems response has been translated into tailored attitudes and a better care for patients with AA worldwide

    Get PDF
    Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters. Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs). Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001). Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio

    Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries
