Matlab-based interface for the simultaneous acquisition of force measures and Doppler ultrasound muscular images
2012
This paper tackles the design of a graphical user interface (GUI) based on Matlab (MathWorks Inc., MA), a worldwide standard in the processing of biosignals, which allows the acquisition of muscular force signals and images from a ultrasound scanner simultaneously. Thus, it is possible to unify two key magnitudes for analyzing the evolution of muscular injuries: the force exerted by the muscle and section/length of the muscle when such force is exerted. This paper describes the modules developed to finally show its applicability with a case study to analyze the functioning capacity of the shoulder rotator cuff.
Applying univariate vs. multivariate statistics to investigate therapeutic efficacy in (pre)clinical trials: A Monte Carlo simulation study on the ex…
2020
BackgroundSmall sample sizes combined with multiple correlated endpoints pose a major challenge in the statistical analysis of preclinical neurotrauma studies. The standard approach of applying univariate tests on individual response variables has the advantage of simplicity of interpretation, but it fails to account for the covariance/correlation in the data. In contrast, multivariate statistical techniques might more adequately capture the multi-dimensional pathophysiological pattern of neurotrauma and therefore provide increased sensitivity to detect treatment effects.ResultsWe systematically evaluated the performance of univariate ANOVA, Welch's ANOVA and linear mixed effects models ver…
Trauma in cirrhosis: an indicator of the pattern of alcohol abuse in different societies.
1991
While some morbidities associated with the excessive use of alcohol are related to the total amount of alcohol consumed--cirrhosis being an example--other pathologies, such as trauma and those of psycho-social origin, are mainly related to the frequency of acute alcoholic intoxication rather than to the total amount consumed. The balance between these two types of alcohol-associated morbidities can provide an indication of the relative frequency of intoxication, and thus of the pattern of alcohol abuse in a population. Since trauma is highly associated with acute alcoholic intoxication, the prevalence of bone fractures was determined in cirrhotics in nine countries. The prevalence of rib an…
Trends in Medically Attended Injuries in Czech Adolescents.
2017
Objective: Due to the importance of surveillance of injuries and accidents in the Czech Republic, the purpose. of this study was to report the temporal trends of injuries of Czech adolescents between 2002 and 2014. Methods: Adolescents (N = 20,038) from the Czech Republic, that took part in the 2002, 2006, 2010 and 2014 HBSC study, reported the frequency of medically attended injuries in the past 12 months. Repeated binary logistic regressions with different years as reference categories were performed. Results: Less than half (44.7%) of all Czech adolescents reported they had experienced at least one medically attended injuries in the past 12 months, with boys experiencing more injuries th…
Potential use of HMG-CoA reductase inhibitors (statins) as radioprotective agents
2011
HMG-CoA reductase inhibitors (statins) are widely used in the therapy of hypercholesterolemia. Apart from their lipid-lowering activity, they have pleiotropic effects that are attributed to the inhibition of regulatory proteins, including Ras-homologous (Rho) GTPases. Here, we discuss the potential usefulness of statins to prevent normal tissue damage provoked by radiotherapy. Statins reduce the mRNA expression of pro-inflammatory and pro-fibrotic cytokines stimulated by ionizing radiation in vitro and alleviate IR-induced inflammation and fibrosis in vivo. The currently available data indicate that statins accelerate the rapid repair of DNA double-strand breaks and, moreover, mitigate the …
Role of Negative Pressure Therapy as Damage Control in Soft Tissue Reconstruction for Open Tibial Fractures.
2017
AbstractThe concept of damage control orthopaedics (DCO) is a strategy that focuses on managing orthopaedic injuries in polytrauma patients who are in an unstable physiological state. The concept of DCO is an extension of damage control surgery or damage limitation surgery (DCS/DLS). Recently, it has become clear that certain patients, following extensive soft tissue trauma, could benefit from the idea of DCS. In the management of severe lower extremity trauma with exposed fracture sites, aggressive early wound excision debridement, early internal fixation, and vascularized wound coverage within a few days after trauma were proposed. A negative-pressure dressing can be easily and rapidly ap…
Ketamine in acute phase of severe traumatic brain injury “an old drug for new uses?”
2021
AbstractMaintaining an adequate level of sedation and analgesia plays a key role in the management of traumatic brain injury (TBI). To date, it is unclear which drug or combination of drugs is most effective in achieving these goals. Ketamine is an agent with attractive pharmacological and pharmacokinetics characteristics. Current evidence shows that ketamine does not increase and may instead decrease intracranial pressure, and its safety profile makes it a reliable tool in the prehospital environment. In this point of view, we discuss different aspects of the use of ketamine in the acute phase of TBI, with its potential benefits and pitfalls.

Intracranial measurement of current densities induced by transcranial magnetic stimulation in the human brain
2003
Transcranial magnetic stimulation (TMS) is a non-invasive technique that uses the principle of electromagnetic induction to generate currents in the brain via pulsed magnetic fields. The magnitude of such induced currents is unknown. In this study we measured the TMS induced current densities in a patient with implanted depth electrodes for epilepsy monitoring. A maximum current density of 12 microA/cm2 was recorded at a depth of 1 cm from scalp surface with the optimum stimulation orientation used in the experiment and an intensity of 7% of the maximal stimulator output. During TMS we recorded relative current variations under different stimulating coil orientations and at different points…

Incluye: Correction: Burden of injury along the development spectrum: associations between the Socio-demographic Index and disability-adjusted life year estimates from the Global Burden of Disease Study 2017. Inj Prev. 2020 Oct;26(Supp 1):i164. doi: 10.1136/injuryprev-2019-043296corr1. Epub 2020 Sep 28. PMID: 32989004 Background: The epidemiological transition of non-communicable diseases replacing infectious diseases as the main contributors to disease burden has been well documented in global health literature. Less focus, however, has been given to the relationship between sociodemographic changes and injury. The aim of this study was to examine the association between disability-adjuste…
