Evaluation of atrial function by 2D strain echocardiography in patients with atrial fibrillation
2012
Abstract Objectives To evaluate atrial function by 2D strain in patients with atrial fibrillation (AF) and normal or slightly increased atrial size and to verify whether lower atrial strain is associated with more frequent AF recurrences. Materials and methods We studied 50 patients with AF, mean age 59.6 ± 13 years and 50 age-and gender-matched controls. We analyzed left atrial function through 2Dstrain imaging, after the re-establishment of sinus rhythm (SR) and we investigated about the recurrences of the arrhythmia. Results Atrial strain (AS) was lower in AF patients vs controls (LA p Conclusions The assessment of atrial function by strain imaging might help to identify patients who nee…
Epidemiological, biological and clinical update on exercise-induced hemolysis
2019
Exercise-induced hemolysis can be conventionally defined as rupture and destruction of erythrocytes during physical exercise. The currently available epidemiologic information attests that a substantial degree of exercise-induced hemolysis is commonplace after short-, medium-, long- and ultra-long distance running, as reflected by significant decrease of serum or plasma haptoglobin and significant increase of plasma concentration (or overall blood content) of free hemoglobin. This paraphysiological intravascular hemolysis is typically mild (average variations of hemolysis biomarkers are usually comprised between 1.2- and 1.8-fold), almost self-limiting (completely resolving within 24-48 hou…
Efficacy of conservative treatments for hand osteoarthritis
2020
Background: Hand osteoarthritis (OA) is common, but the efficacy/safety of treatment interventions aimed to improve health outcomes in this population are not well understood. Therefore, the aim of this study was to map and grade the effect of interventions for health outcomes in hand OA. Methods: Umbrella review of systematic reviews with meta-analyses of randomized controlled trials (RCTs) using placebo/no intervention as control group. For outcomes with a p-value <0.05, the certainty of the evidence was evaluated using the grading of recommendations assessment, development and evaluation (GRADE) assessment. Results: From 189 abstracts, 9 meta-analyses (24 outcomes) were included, with…
Detection of central circuits implicated in the formation of novel pain memories
2016
Jaymin Upadhyay,1 Julia Granitzka,1 Thomas Bauermann,2 Ulf Baumg&auml;rtner,3 Markus Breimhorst,1 Rolf-Detlef Treede,3 Frank Birklein1 1Department of Neurology, 2Department of Neuroradiology, University Medical Centre, Johannes Gutenberg University Mainz, Mainz, 3Department of Neurophysiology, Center for Biomedicine and Medical Technology Mannheim (CBTM), Heidelberg University, Mannheim, Germany Abstract: Being able to remember physically and emotionally painful events in one&rsquo;s own past may shape behavior, and can create an aversion to a variety of situations. Pain imagination is a related process that may include recall of past experiences, in addition to production of sensor…
Effects of aquatic and dry land resistance training devices on body composition and physical capacity in postmenopausal women.
2013
Effects of Aquatic and Dry Land Resistance Training Devices on Body Composition and Physical Capacity in Postmenopausal Women To determine the effects of a supervised strength training program on body composition and physical capacity of older women using three different devices: weight machines, elastic bands, and aquatic devices that increase drag forces (ADIDF). Four groups were formed: control group, weight machine group (WMG), elastic band group (EBG) and a group that used ADIDF (ADIDFG). Body composition and physical capacity were assessed before and after the intervention period. The ADIDFG showed improvements in fat mass (FM), fat-free mass of the left arm (FFM-LA) and right arm (FF…
Computed Tomography in Brain Tumors
1981
Craniocerebral injury and brain tumor are the two most important indications for CT studies. There is unanimous agreement that computed tomography is unequalled in its diagnostic accuracy in demonstration of intracranial tumors. Our own experience is based on observations in 3,750 patients with brain tumors or cerebral metastases who were studied in the period from December 1974 to March 1980 (Table 1). Initial CT studies demonstrated the intracranial tumor or tumors in 3,589 cases (95.7%). Several CT examinations were necessary for diagnosis of a brain tumor in 112 patients (3.0%). Other diagnostic procedures or postmortem studies revealed a brain tumor which had not been demonstrated with…
Postural Adaptations in Preadolescent Karate Athletes Due to a One Week Karate Training Camp
2013
Abstract The aim of this study was to investigate the effect of an increasing number of training hours of specific highintensity karate training on postural sway in preadolescent karate athletes. Seventy-four karatekas were randomly assigned to 1 of 2 groups: Karate Group (KG=37): age 10.29±1.68 yrs; or Control Group (CG= 37): age 10.06±1.77 yrs. The KG performed two sessions per day for 1 week in total, while the CG performed only 3 sessions during the same period. The center-of-pressure length (COPL) and velocity (COPV) were recorded under four different experimental conditions: open eyes (EO), closed eyes (EC), open eyes monopodalic left (EOL), open eyes monopodalic right (EOR), pre as w…
Investigation of the Effect of Mode and Tempo on Emotional Responses to Music Using EEG Power Asymmetry
2013
The combined interactions of mode and tempo on emotional responses to music were investigated using both self-reports and electroencephalogram (EEG) activity. A musical excerpt was performed in three different modes and tempi. Participants rated the emotional content of the resulting nine stimuli and their EEG activity was recorded. Musical modes influence the valence of emotion with major mode being evaluated happier and more serene, than minor and locrian modes. In EEG frontal activity, major mode was associated with an increased alpha activation in the left hemisphere compared to minor and locrian modes, which, in turn, induced increased activation in the right hemisphere. The tempo mod…
Independent component analysis on the mismatch negativity in an uninterrupted sound paradigm.
2008
We compared the efficiency of the independent component analysis (ICA) decomposition procedure against the difference wave (DW) and optimal digital filtering (ODF) procedures in the analysis of the mismatch negativity (MMN). The comparison was made in a group of 54 children aged 8-16 years. The MMN was elicited in a passive oddball protocol presenting uninterrupted auditory stimulation consisting of two frequent alternating tones (600 and 800 Hz) of 100 ms duration each. Infrequently, one of the 600 Hz tones was shortened to 50 or 30 ms. The event related potentials (ERPs) were decomposed into the MMN-like and non-MMN-like independent components (ICs) through the FastICA algorithm. The ICA …
Auditory Training in Deaf Children
2010
Deaf children are, earlier than in the past, identified and can benefit of new and highperformance devices (as cochlear implants or digital hearing aids). However, a great variability in their spoken language skills is observed (12) and first attributable to the well-known effect of the age of auditory rehabilitation (15, 16, 17, 18, 19, 20, 21, 22). The second assessment concerns the way speech disorders are treated: new technologies are not linked to any change in the way speech therapy is delivered, particularly in the field of auditory training. Auditory training constitutes an important part of the speech therapy addressed to the deaf children and must start as soon as possible. The go…
