Teoría de la mente y funcionalidad en pacientes bipolares en remisión sintomática
2013
Introducción: Los déficits en la funcionalidad son comunes durante la remisión en el trastorno bipolar (TB). Adicionalmente, existe evidencia de alteraciones en la cognición social en remisión clínica. Estos déficits podrían contribuir a la disfunción observada en estos pacientes. Material y métodos: Doce pacientes bipolares en remisión sintomática (7 bipolares tipo i y 5 de tipo ii) y 12 individuos controles sin patología psiquiátrica completaron el Test de las Miradas y el Test de Faux Pas para evaluar teoría de la mente (ToM), y el Test Breve para la Evaluación de la Funcionalidad (FAST). Resultados: El desempeño de los pacientes bipolares en el aspecto cognitivo de la ToM se ubicó por d…
Evoked otoacoustic emissions and pure tone threshold audiometry in patients receiving cisplatinum therapy.
1993
Eight children and young adults with cancer were evaluated serially using pure tone audiometry as well as registration of click-evoked otoacoustic emissions (EOAE) 1 day prior to therapy as well as after various numbers of doses of cisplatinum. A reduction of EOAE-amplitudes following cisplatinum therapy was observed in all patients. This reduction tended to recover after the end of cisplatinum administration. Since EOAE are believed to result from cochlear bio-mechanical processes, the reduced emissions are interpreted as signs of cochlear dysfunction. We conclude, that EOAE testing may be a simple, non-invasive method that may detect early, transient functional impairment of hearing due t…
Functional signs in patients consulting for presumed Lyme borreliosis
2019
Little is known about the functional symptoms associated with Lyme borreliosis (LB) in Europe. We aimed to assess functional symptoms associated with presumed LB and to compare patients with and without confirmed LB.We performed a retrospective monocenter study. Patients consulting for presumed LB were included.Between November 2015 and June 2018, 355patients were included (mean age: 51years, 52% of women) of which 48had LB: erythema migrans (42%), early disseminated LB (50%; 35% of neuroborreliosis cases), and late disseminated LB (8%). The most frequently reported functional symptoms were neuropathic pain (23%), arthralgia (23%), and asthenia (17%). Other functional symptoms were rare (≤1…
Neuromuscular adaptations during bilateral versus unilateral strength training in middle-aged and elderly men and women.
1996
Twelve middle-aged men and 12 middle-aged women in the 50-year-old age group (M50; range 44-57 years; W50; 43-57), and 12 elderly men and 12 elderly women in the 70-year-old age group (M70; 59-75; W70; 62-75) volunteered as subjects in order to examine effects of 12-week progressive heavy resistance strength training on electromyographic activity (EMG), muscle cross-sectional area (CSA) of the quadriceps femoris and maximal concentric force in a one repetition maximum (1 RM) test of the knee extensor muscles. One half of the subjects in each group performed the knee extension (and flexion) exercises only bilaterally (BIL), while another half performed the exercises only unilaterally (UNIL).…
Genetic, andrological and clinical characteristics of patients with congenital bilateral absence of vas deferens
2001
Summary The possibility of retrieving spermatozoa from the epididymis allows patients with congenital bilateral absence of the vas deferens (CBAVD) to father a child by means of assisted reproduction techniques. This has, however, increased the chance of transmitting a mutated allele of the cystic fibrosis transmembrane conductance regulator (CFTR) gene which increases the risk of generating offspring with cystic fibrosis (CF). Because of the increased heterogeneity of the CFTR locus, the study of a discrete number of mutations, as usually carried out in a diagnostic work-up, is unable to ascertain the presence of a mutation in a relatively high proportion of the patients screened. In an at…
Characterization of BOLD-fMRI signal during a verbal fluency paradigm in patients with intracerebral tumors affecting the frontal lobe.
2002
Previous studies have indicated that the BOLD-fMRI signal can be modified by tumor processes in close vicinity to functional brain areas. This effect has been investigated primarily for the perirolandic area but there is only a limited number of studies concerning frontal cortical regions. Therefore, the aim of the current study was to characterize BOLD-fMRI signal and activation patterns in patients with frontal brain tumors while performing a verbal fluency task. Six patients (ages 31-56 years) suffering from frontal (5 left sided and 1 right sided) intracerebral tumors were examined with fMRI while performing a verbal fluency task in a blocked paradigm design. Eight healthy volunteers se…
Region-dependent hamstrings activity in Nordic hamstring exercise and stiff-leg deadlift defined with high-density electromyography
2018
Recent studies suggest region-specific metabolic activity in hamstring muscles during injury prevention exercises, but the neural representation of this phenomenon is unknown. The aim of this study was to examine whether regional differences are evident in the activity of biceps femoris long head (BFlh) and semitendinosus (ST) muscles during two common injury prevention exercises. Twelve male participants without a history of hamstring injury performed the Nordic hamstring exercise (NHE) and stiff-leg deadlift (SDL) while BFlh and ST activities were recorded with high-density electromyography (HD-EMG). Normalized activity was calculated from the distal, middle, and proximal regions in the e…
Distribution and categorization of left ventricular measurements in the general population: results from the population-based Gutenberg Heart Study.
2010
Background— Echocardiography, the dominant imaging modality for quantification of left ventricular metrics, has undergone continuing development in the past few decades. However, given the lack of population-based data, current guidelines are still based on restricted and small data sets analyzed with methods including expert opinion. This work presents empirically derived reference values from a large-scale, epidemiologic study conducted with state-of-the-art imaging technology and methods. Methods and Results— The distribution of echocardiographic measurements of the left ventricle was analyzed in a population-based sample of 5000 mid-Europeans from the Gutenberg Heart Study in Germany. …
Left ventricular volume determination using Albunex.
1996
The aim of this study was to assess the ability of intravenous injection of Albunex to improve left ventricular volume determination in patients with various cardiac diseases. It is conceivable that the intravenous injection of microbubbles could improve echocardiographic left ventricular border delineation leading to improved interobserver variability. Echocardiograms were obtained during simultaneous intravenous injection of 0.08 and 0.12 ml/kg Albunex (four-chamber view). Within 6 hours after the recording of the contrast echocardiograms routine left heart angiography was performed. Volumes were measured using the slice method in native and contrast echocardiograms as well as in the angi…
Plasma levels of atrial natriuretic peptide and hemodynamic function in cardiac disease.
1993
Plasma concentrations of atrial natriuretic peptide were measured in eight patients with cardiac disease but normal resting right atrial pressure, during cardiac catheterization. No patient had clinical evidence of overt heart failure. An increase in peptide concentrations was observed between the aorta or the peripheral vein and the pulmonary artery. A linear relation was found between peripheral vein and pulmonary artery peptide concentration. Mean pulmonary artery and capillary wedge pressure also correlated with the peptide levels. No correlation was observed between mean right atrial pressure and peptide concentration. These findings demonstrate that atrial natriuretic peptide release,…
