Resilienz bei Rehabilitanden der Orthopädie und Psychosomatik : Eine Querschnittstudie

Theoretical background: The construct of resilience is now used in many fields, such as in sports, corporate governance and in health care system. Against the backdrop of the unique system of rehabilitation in Germany, that empowers people to participate in a social and pro-fessional way, the concept of resilience is becoming increasingly important. Accordingly this cross-sectional study should explore the resilience of orthopedic and psychosomatic patients in more detail.Questions: Are there differences in the sample that lead to different sub-samples based on the RS-13? Are there differences between the sub-samples in terms of socio-demographic data, psychosocial problems, psychological stress, stress in the workplace and the experi-ence of stress? Do socio-demografic, employment, psycho-social and psychological varia-bles influence resilience?Method: For this investigation the data of n = 131 patients was used. The data was collected in an orthopedic clinic of rehabilitation and in a psychosomatic clinic of rehabilitation. On the basis of the results of the short Resiliencescale RS-13 the sample was split into two sub-samples of N1 = 51 patients with low resilience and N2 = 80 patients with higher resilience. The questions were examined by regarding the Brief Symptom Checklist (BSCL), the Ultra-Kurz-Screening (UKS), the Stressscale (from the DASS-Questionnaire) and the Employee Attitude Survey (BAuA). Additionally a literature research was done in databases like Psy-Content, Psyndex and Springerlink to acquire the theoretical background.Results: Within the sample, there were two sub-samples, one which included patients with low resilience while the other was characterized by high resilience. Patients with low resili-ence did not differ by considering the variables of age, sex, marital status, children, educa-tion, occupational status, industry and job stress. Patients with high resilience are older and rarer incap

A mathematical model to describe fat oxidation kinetics during graded exercise.

PURPOSE: The purpose of this study was to develop a mathematical model (sine model, SIN) to describe fat oxidation kinetics as a function of the relative exercise intensity [% of maximal oxygen uptake (%VO2max)] during graded exercise and to determine the exercise intensity (Fatmax) that elicits maximal fat oxidation (MFO) and the intensity at which the fat oxidation becomes negligible (Fatmin). This model included three independent variables (dilatation, symmetry, and translation) that incorporated primary expected modulations of the curve because of training level or body composition. METHODS: Thirty-two healthy volunteers (17 women and 15 men) performed a graded exercise test on a cycle ergometer, with 3-min stages and 20-W increments. Substrate oxidation rates were determined using indirect calorimetry. SIN was compared with measured values (MV) and with other methods currently used [i.e., the RER method (MRER) and third polynomial curves (P3)]. RESULTS: There was no significant difference in the fitting accuracy between SIN and P3 (P = 0.157), whereas MRER was less precise than SIN (P < 0.001). Fatmax (44 +/- 10% VO2max) and MFO (0.37 +/- 0.16 g x min(-1)) determined using SIN were significantly correlated with MV, P3, and MRER (P < 0.001). The variable of dilatation was correlated with Fatmax, Fatmin, and MFO (r = 0.79, r = 0.67, and r = 0.60, respectively, P < 0.001). CONCLUSIONS: The SIN model presents the same precision as other methods currently used in the determination of Fatmax and MFO but in addition allows calculation of Fatmin. Moreover, the three independent variables are directly related to the main expected modulations of the fat oxidation curve. SIN, therefore, seems to be an appropriate tool in analyzing fat oxidation kinetics obtained during graded exercise.

Anti-doping testing at the 2008 European football championship.

Big sports events like the 2008 European Football Championship are a challenge for anti-doping activities, particularly when the sports event is hosted by two different countries and there are two laboratories accredited by the World Anti-Doping Agency. This challenges the logistics of sample collection as well as the chemical analyses, which must be carried out timeously. The following paper discusses the handling of whereabouts information for each athlete and the therapeutic use exemption system, experiences in sample collection and transportation of blood and urine samples, and the results of the chemical analysis in two different accredited laboratories. An overview of the analytical results of blood profiling and growth hormone testing in comparison with the distribution of the normal population is also presented.

Maximal Physiological Parameters during Partial Body-Weight Support Treadmill Testing.

PURPOSE: This study investigated maximal cardiometabolic response while running in a lower body positive pressure treadmill (antigravity treadmill (AG)), which reduces body weight (BW) and impact. The AG is used in rehabilitation of injuries but could have potential for high-speed running, if workload is maximally elevated. METHODS: Fourteen trained (nine male) runners (age 27 ± 5 yr; 10-km personal best, 38.1 ± 1.1 min) completed a treadmill incremental test (CON) to measure aerobic capacity and heart rate (V˙O2max and HRmax). They completed four identical tests (48 h apart, randomized order) on the AG at BW of 100%, 95%, 90%, and 85% (AG100 to AG85). Stride length and rate were measured at peak velocities (Vpeak). RESULTS: V˙O2max (mL·kg·min) was similar across all conditions (men: CON = 66.6 (3.0), AG100 = 65.6 (3.8), AG95 = 65.0 (5.4), AG90 = 65.6 (4.5), and AG85 = 65.0 (4.8); women: CON = 63.0 (4.6), AG100 = 61.4 (4.3), AG95 = 60.7 (4.8), AG90 = 61.4 (3.3), and AG85 = 62.8 (3.9)). Similar results were found for HRmax, except for AG85 in men and AG100 and AG90 in women, which were lower than CON. Vpeak (km·h) in men was 19.7 (0.9) in CON, which was lower than every other condition: AG100 = 21.0 (1.9) (P < 0.05), AG95 = 21.4 (1.8) (P < 0.01), AG90 = 22.3 (2.1) (P < 0.01), and AG85 = 22.6 (1.6) (P < 0.001). In women, Vpeak (km·h) was similar between CON (17.8 (1.1) ) and AG100 (19.3 (1.0)) but higher at AG95 = 19.5 (0.4) (P < 0.05), AG90 = 19.5 (0.8) (P < 0.05), and AG85 = 21.2 (0.9) (P < 0.01). CONCLUSIONS: The AG can be used at maximal exercise intensities at BW of 85% to 95%, reaching faster running speeds than normally feasible. The AG could be used for overspeed running programs at the highest metabolic response levels.

Techniques for analytical testing of unconventional samples.

Forensic scientists have long detected the presence of drugs and their metabolites in biological materials using body fluids such as urine, blood and/or other biological liquids or tissues. For doping analysis, only urine has so far been collected. In recent years, remarkable advances in sensitive analytical techniques have encouraged the analysis of drugs in unconventional biological samples such as hair, saliva and sweat. These samples are easily collected, although drug levels are often lower than the corresponding levels in urine or blood. This chapter reviews recent studies in the detection of doping agents in hair, saliva and sweat. Sampling, analytical procedures and interpretation of the results are discussed in comparison with those obtained from urine and blood samples.

Test methods: anabolics.

In the International Olympic Committee (IOC) accredited laboratories, specific methods have been developed to detect anabolic steroids in athletes' urine. The technique of choice to achieve this is gas-chromatography coupled with mass spectrometry (GC-MS). In order to improve the efficiency of anti-doping programmes, the laboratories have defined new analytical strategies. The final sensitivity of the analytical procedure can be improved by choosing new technologies for use in detection, such as tandem mass spectrometry (MS-MS) or high resolution mass spectrometry (HRMS). A better sample preparation using immuno-affinity chromatography (IAC) is also a good tool for improving sensitivity. These techniques are suitable for the detection of synthetic anabolic steroids whose structure is not found naturally in the human body. The more and more evident use, on a large scale, of substances chemically similar to the endogenous steroids obliges both the laboratory and the sports authorities to use the steroid profile of the athlete in comparison with reference ranges from a population or with intraindividual reference values.

Criteris d'avaluació de la credibilitat en les denúncies de violència de gènere

La Llei Integral de Mesures contra la Violència de Gènere estableix una sèrie de mesures legislatives que tenen per objecte el reconeixement dels drets de les víctimes de la violència, enfortir la sensibilitat ciutadana davant de la violència de gènere, instaurar un sistema de serveis socials d’atenció i de recuperació de les víctimes, garantir els seus drets econòmics i laborals, instaurar un sistema institucional de tutela, determinar un marc penal i processal i garantir la coordinació de tots aquells recursos que es dediquen a aquesta qüestió. Conscients de la importància d’aquesta Llei, de les dificultats que deriven de la seva aplicació, així com de la nostra experiència en la pràctica forense en casos de violència domèstica i de gènere, neix la idea de realitzar la recerca d’aquest estudi. Una recerca que pretén establir, a partir de l’anàlisi dels relats de dones víctimes de violència de gènere en la relació de parella, criteris de credibilitat que permetin validar les seves declaracions. Criteris obtinguts a partir de les mateixes paraules de les víctimes. Partint d’una metodologia mixta, quantitativa i qualitativa, hem obtingut uns resultats que ens han permès definir un sistema de criteris de credibilitat genuïns i discriminadors. Una discriminació obtinguda a partir de la comparació de les declaracions de dues mostres: víctimes reals i víctimes simulades. I, fruit d’aquesta comparació, la discontinuïtat narrativa, els detalls estranys, la reproducció de converses, les correccions espontànies, l’ambivalència i ambigüitat vers l’agressor, la violència indirecta, suscitant por i terror, la por a les represàlies, la imposició i intimitat del secret, la indefensió, l’evolució de la violència i progressió de la asimetria de poder, la dualitat de la conducta domèstica / imatge social de l’home, el control ampli masculí cognitiu-conductual, la descripció contextualitzada de microviolències, les estratègies de supervivència de la dona i el relat inhibit amb vergonya, han resultat criteris de credibilitat de les dones víctimes de violència de gènere que ens permetran validar el seu relat.

Criterios de evaluación de la credibilidad en las denuncias de violencia de género

Esta investigación contrasta los relatos de dos muestras de mujeres. La primera, víctimas reales de violencia de género en la relación de pareja; la segunda, deliberadamente ofrecen relatos falsos sobre esta misma problemática. Los resultados muestran una diferencia cualitativa significativa en base a los criterios de credibilidad definidos. Al mismo tiempo, el estudio ha encontrado otros criterios de credibilidad genuinos, que conforman el discurso explicativo que permite validar sus declaraciones.

L’Impacte penal i penitenciari de la violència de gènere a Catalunya

L’estudi vol fer una prospecció quantitativa i qualitativa en relació a l’impacte en el sistema penal i penitenciari català de l’aplicació de la Llei Orgànica 1/2004 de Mesures de Protecció Integral contra la violència de gènere en la seva vessant de tutela penal, i emmarcat en l’àmbit de Catalunya. A l’estudi es recull l’opinió de diversos serveis i operadors que actuen al voltant del sistema penal i penitenciari a Catalunya, per tal de fer una primera aproximació a l’impacte dels nous dispositius legislatius i jurisdiccionals. Aquesta aproximació és una radiografia actualitzada del que està suposant la posada en marxa de la legislació vigent i l’abast de l’abordatge penal i penitenciari de la violència domèstica / de gènere. La recerca recull també l’opinió de les víctimes i, com a contrast, la dels condemnats per violència contra les dones, a partir del buidatge de 58 entrevistes realitzades a 30 víctimes i 28 agressors. D’aquests, la meitat ingressats a presó i l’altra meitat amb mesures penals alternatives. La recerca finalitza fent tot un seguit de recomanacions finals per millorar l’atenció efectiva i integral a la víctima de violència de gènere.

Central nervous system stimulants and sport practice.

BACKGROUND AND OBJECTIVES: Central nervous system (CNS) stimulants may be used to reduce tiredness and increase alertness, competitiveness, and aggression. They are more likely to be used in competition but may be used during training to increase the intensity of the training session. There are several potential dangers involving their misuse in contact sports. This paper reviews the three main CNS stimulants, ephedrine, amfetamine, and cocaine, in relation to misuse in sport. METHODS: Description of the pharmacology, actions, and side effects of amfetamine, cocaine, and ephedrine. RESULTS: CNS stimulants have psychotropic effects that may be perceived to be ergogenic. Some are prescription drugs, such as Ephedra alkaloids, and there are issues regarding their appropriate therapeutic use. Recently attention has been given to their widespread use by athletes, despite the lack of evidence regarding any ergogenic or real performance benefit, and their potentially serious side effects. Recreational drugs, some of which are illegal (cocaine, amfetamines), are commonly used by athletes and cause potential ergolytic effects. Overall, these drugs are important for their frequent use and mention in anti-doping laboratories statistics and the media, and their potentially serious adverse effects. CONCLUSIONS: Doping with CNS stimulants is a real public health problem and all sports authorities should participate in its prevention. Dissemination of information is essential to prevent doping in sport and to provide alternatives. Adequate training and education in this domain should be introduced.
