Anthropometric and physical characteristics allow differentiation of young female volleyball players according to playing position and level of exper…

2017

The aim of our study was to determine the differences in some anthropometric and physical performance variables of young Croatian female volleyball players (aged 13 to 15) in relation to playing position (i.e., independent variable) and performance level within each position (i.e., independent variable). Players were categorized according to playing position (i.e., role) as middle blockers (n=28), opposite hitters (n=41), passer-hitters (n=54), setters (n=30), and liberos (n=28). Within each position, players were divided into a more successful group and a less successful group according to team ranking in the latest regional championship and player quality within the team. Height and body …

Neurobiological and Clinical Variables Associated with Alcohol Abuse in Bulimia Nervosa

2015

The study was aimed at analysing the reciprocal relationships of several clinical and neurobiological items in order to predict alcohol misuse in patients with bulimia nervosa (BN). Seventy BN patients and 70 healthy controls were assessed for depression, impulsivity, borderline personality traits and self-defeating behaviours using specific scales; serum cortisol and 24-hour urinary excretion of serotonin and 5-hydroxiindolacetic acid were also assessed. The study confirmed the implications of these clinical factors for alcohol misuse in BN patients, but the results suggested that depressive symptoms and hypercortisolism could lie behind these relationships.

Prehospital diagnosis in stroke patients-differentiation between cerebral ischemic events and cerebral hemorrhage

1996

A large number of stroke patients is treated by the Mainz-EMS during the first hours after the onset of symptoms. A combination of anamnestic and clinical variables included in the score prehospitally leads to the tentative diagnosis confirmed by CT-scan in the majority of cases. It should therefore be possible in the future to initiate specific therapy for stroke patients prehospitally.

Temporal pole morphology in first-episode schizophrenia patients:

2010

Studies of the temporal pole (TP) in schizophrenia patients are not consistent. The aim of this study was to investigate morphometric anomalies of the TP in first-episode schizophrenia patients. Patients did not significantly differ from controls in the TP morphometric variables evaluated. Clinical variables were not significantly related to the TP.

New prognostic markers in neuroblastoma

2013

Introduction: The hallmark of neuroblastoma is its clinical and biological heterogeneity, with the likelihood of cure varying widely according to age at diagnosis, extent of disease and tumor biology. We hope this review will be useful for understanding part of the unfamiliar neuroblastoma codex. Areas covered: In the first part of this review, the authors summarize the currently used prognostic factors for risk-adapted therapy, with the focus on clinical management of neuroblastoma patients. In the second part, the authors discuss the evolving prognostic factors for future treatment schemes. A search of online medical research databases was undertaken focusing especially on literature publ…

Differences in clinical variables and risk factors between patients with osteoarthritis and osteoarthrosis of the temporomandibular joint (TMJ)

2011

Objective: To study differences in risk factors and clinical variables between a group of patients with osteoarthritis and a group with osteoarthrosis of the temporomandibular joint. Material and methods: Thirty-five patients (32 women and 3 men) (mean age 53±18 years), 21 (60%) with a diagnosis of osteoarthrosis (mean age 54.7±20.2 years) and 14 (40%) with a diagnosis of osteoarthritis (mean age 51.7±16.9 years), were studied. The two groups were compared with each other and also with the group of 164 patients with temporomandibular joint pathology from which they were drawn. An evaluation was made of the demographic variables, risk factors (parafunctions, posterior occlusal contacts, slee…

Evaluation of the Complexity of Myocardial Activation During Ventricular Fibrillation. An Experimental Study

2013

A B S T R A C T Introduction and objectives: An experimental model is used to analyze the characteristics of ventricular fibrillation in situations of variable complexity, establishing relationships among the data produced by different methods for analyzing the arrhythmia. Methods: In 27 isolated rabbit heart preparations studied under the action of drugs (propranolol and KB-R7943) or physical procedures (stretching) that produce different degrees of change in the complexity of myocardial activation during ventricular fibrillation, use was made of spectral, morphological, and mapping techniques to process the recordings obtained with epicardial multielectrodes. Results: The complexity of ve…

Cardiorespiratory Coordination after Training and Detraining. A Principal Component Analysis Approach

2016

Our purpose was to study the effects of different training modalities and detraining on cardiorespiratory coordination (CRC). Thirty-two young males were randomly assigned to four training groups: aerobic (AT), resistance (RT), aerobic plus resistance (AT + RT), and control (C). They were assessed before training, after training (6 weeks) and after detraining (3 weeks) by means of a graded maximal test. A principal component (PC) analysis of selected cardiovascular and cardiorespiratory variables was performed to evaluate CRC. The first PC (PC1) coefficient of congruence in the three conditions (before training, after training and after detraining) was compared between groups. Two PCs were …

Physical activity - an important preanalytical variable

2014

The concentration of several biochemical and hematological biomarkers is strongly influenced by a number of preanalytical variables. Several lines of evidence attest that short, middle, and long-term exercise, as well as the relative intensity of physical effort (from mild to strenuous), may influence a broad array of laboratory variables. The amount of extracellular release and clearance from blood of most of these biomarkers is markedly influenced by the biological characteristics of the molecule(s), level of training, type, intensity and duration of exercise, and time of recovery after training. It is hence noteworthy that test results that fall outside the conventional reference ranges …
