ECG diagnostics in competitive athletes. Current implications for preparticipation screening

In young competitive athletes sudden cardiac death frequently occurs as a tragic first manifestation of clinically inapparent underlying structural or electrical cardiac disorders. An increased risk may be reflected by typical electrocardiogram (ECG) alterations preceding symptoms but a correct interpretation is often challenging due to a high prevalence of training-related ECG alterations in competitive athletes mimicking such disorders. Misinterpretation may thus result in either unnecessary disqualification from competitive sports or continuation despite an increased risk or extensive diagnostic work-ups yielding additional equivocal findings. However, as observed in large athlete cohorts in recent years a variety of ECG alterations, such as isolated increased QRS voltage, early repolarization, sinus bradycardia, first degree AV block or incomplete right bundle branch block, represent common variants of ECGs of athletes reflecting physiological and training-related cardiac adaptations. These alterations do not usually require further diagnostic evaluation. In contrast, alterations such as repolarization abnormalities, complete bundle branch block, prolonged QT intervals or pathological Q waves, are strongly suggestive of underlying disorders and require further evaluation even in asymptomatic athletes. Thus, the ECG plays a pivotal role in the prevention of sudden cardiac death in competitive athletes. The present article summarizes current recommendations for the interpretation of athlete ECGs regarding the differentiation between physiological or pathological cardiac adaptation.     

Different levels of implicit emotional recognition in posterior cortical atrophy (PCA)

Previous single-case reports in posterior cortical atrophy (PCA) have shown preserved nonconscious visual recognition despite the absence of explicit recognition. In this study, we investigated three levels of visual recognition in both a female patient with PCA and a control group during the presentation of neutral, positive, and negative affective stimuli. Our results confirmed the profile of impaired explicit recognition and intact psychophysiological responses in the patient. In addition, she was able to implicitly recognize the valence and intensity of arousal of these stimuli. We suggest that implicit emotional awareness may mediates explicit and psychophysiological recognition in PCA.     

Vorhersageparameter für das Vorliegen eines Residualtumors bei der TUR-B-Nachresektion

Background

European Association of Urology (EAU) guidelines recommend a follow-up transurethral resection of bladder tumors (reTUR-B) for intermediate and high-risk non-muscle invasive bladder cancer (NMIBC) 2-6 weeks after the initial resection. The purpose of this study was to find parameters which indicate the presence of residual tumor in reTUR-B and to evaluate the prognostic value.

Patients and methods

The data from all patients treated with TUR-B between January 2005 and December 2008 were retrospectively evaluated. The residual tumor rate was correlated with age, sex, staging, grading, risk group, multifocality and surgeon’s level of training.

Results

A total number of 555 TUR-B operations were carried out and 179 patients received reTUR-B according to the EAU guidelines. Age (p=0.8), sex (p=0.7), initial staging (p=0.2), initial grading (p=0.3) and surgeon’s level of training (p=0.7) did not have an impact on the rate of residual tumor in reTUR-B. Tumors categorized as high risk according to the EAU risk score in initial TUR-B (p<0.01) and multifocality (p=0.01) were associated with significantly higher rates of residual tumor.

Conclusions

A reTUR-B is strongly indicated in high risk bladder tumors as well as multifocal tumors showing a significantly increased residual tumor rate. Other clinical parameters showed no prognostic value for the existence of residual tumor in reTUR-B.
