Another Chance for Medtronic ’s Renal Denervation Therapy
Medtronic has yet another chance to prove its renal denervation therapy can treat uncontrolled hypertension. The Dublin-based company has received FDA approval to begin a clinical trial to evaluate the Symplicity Spyral renal denervation system with patients on medication for high blood pressure. The ON MED Trial is a 2:1 randomized, sham-controlled study and will randomize up to 340 patients at 55 centers in the U.S., Japan, Europe, Australia and Canada. Patients will be followed out to three years. Primary safety endpoints will include major adverse events at one month and new renal artery stenosis at six months. The pri...

{beta}1-Blockade increases maximal apnea duration in elite breath-hold divers
We hypothesized that the cardioselective β1-adrenoreceptor antagonist esmolol would improve maximal apnea duration in elite breath-hold divers. In elite national-level divers (n = 9), maximal apneas were performed in a randomized and counterbalanced order while receiving either iv esmolol (150 μg·kg–1·min–1) or volume-matched saline (placebo). During apnea, heart rate (ECG), beat-by-beat blood pressure, stroke volume (SV), cardiac output (CO), and total peripheral resistance (TPR) were measured (finger photoplethysmography). Myocardial oxygen consumption (MVo2) was estimated from rate pres...

Erectile Dysfunction in Individuals with Neurologic Disability: A Hospital-based Cross-sectional Study
Conclusion: The occurence of erectile dysfunction is significantly more prevalent among neurologically disabled men, particularly those with lesions below S2–S4, than among men without neurologic disability. Considering the prevalence of erectile dysfunction among neurologically disabled men, sexual functioning should be regularly evaluated during acute and long-term rehabilitation, and any existing sexual dysfunction should be addressed in the treatment plan. Introduction Penile erection is a neurovascular event characterized by the dilation of arteries that cause the corpora cavernosa and corpora spongiosum of the peni...

Treatment with betablockers is associated with higher grey-scale median in carotid plaques
Conclusions: These results suggest the use of standardized ultrasound techniques as an important tool in evaluating the effect of anti-atherosclerotic medications and underline the need of.further prospective randomized studies on larger patient cohorts in order to confirm these results.

Carotid stenting in asymptomatic patients: how to identify patients without symptoms and at high risk for neurologic events.
Abstract During the last 20 years, asymptomatic patients with high-grade carotid stenosis have been treated with carotid endarterectomy and more recently with carotid artery stenting in order to prevent stroke. New, best medical treatment including statins, beta-blockers, antiplatelet therapies, and better diabetes and blood pressure control might reduce the incidence of stroke in this patient population making invasive treatment unnecessary. However, patients with asymptomatic carotid stenosis cannot be considered a homogenous population, and therefore, the therapeutic approach should take into consideration a su...
