Internal Jugular Vein Catheterization under Echographic Guidance

Having examined the various disadvantages of the catheterization of the central veins performed using the Seldinger technique, we report our results of internal jugular vein catheterization under echographic guidance in 38 uremic patients. The echographic guidance technique allows an easier and safer utilization of the internal jugular vein as vascular access in emergency situations. </jats:p

Comparison of some serum copper parameters in trained runners and control subjects

The serum copper parameters were evaluated in 41 male trained runners and in a control group of 24 male subjects engaged in normal physical activity. In the runner group lower serum copper concentrations, lower serum ceruloplasmin biological activity, and higher serum ceruloplasmin levels were found compared with the control group. Reduced serum copper levels may affect the ceruloplasmin biological activity, even if the serum ceruloplasmin levels are higher. The results suggest that more attention should be paid to serum copper and ceruloplasmin in athletes

Immediate effects of trunk rotator stretching exercise on gait parameters in subjects with Parkinson’s disease: a randomized clinical trial

Introduction Reduced trunk rotation and pelvic mobility, which are associated with a higher risk of falling and one of the best predictors of gait improvement following rehabilitation [1], are characteristics of subjects with Parkinson's disease (swPD) [2]. The Progressive Modular Rebalancing System (PMR) proved to be an effective multimodal exercise therapy strategy with a trunk mobility focus that can enhance the effects of cognitive strategies in swPD gait training [3]. The purpose of this study was to compare the immediate effects of PMR trunk rotator stretching exercise to active upper trunk rotation exercise (Control) on gait parameters in swPD. Methods An expert neurologist screened 40 swPD for inclusion before randomly assigning them to the PMR or control exercise groups using sealed envelopes. Gait trials were collected using a magneto-inertial measurement unit placed at the lower back before (T0) and immediately after (T1) a single exercise session. Spatio-temporal parameters, pelvic kinematics, and harmonic ratios (HR) in three spatial directions were calculated. Four physical therapists who were not aware of the gait assessment carried out the PMR or control exercise. The entire procedure took between 10 and 15 minutes. To assess differences between groups, the independent sample t-test or Mann-Whitney test was used. Within-group differences were assessed using the paired sample t-test or the Wilcoxon test. Results At T1, there were significant differences in pelvic obliquity and HR in the antero-posterior (AP) direction between the PMR and control groups (Fig. 1). The PMR group improved in pelvic obliquity, pelvic rotation, HR in the AP and medio-lateral directions, gait speed and cadence, and double support time. Pelvic obliquity and cadence improved in the control group (Fig. 1).Discussion PMR trunk rotation stretching was more effective than upper trunk rotation exercise in improving pelvic mobility and harmonic ratio during gait in swPD in a single exercise session. Implementing a PMR trunk rotation stretching exercise into a gait rehabilitation program may enhance the effects of gait training by improving pelvic mobility and trunk behavior during gait
