Identifying time-varying dynamics of heart rate and oxygen uptake from single ramp incremental running tests.

The fact that ramp incremental exercise yields quasi-linear responses for pulmonary oxygen uptake (V˙O2) and heart rate (HR) seems contradictory to the well-known non-linear behavior of underlying physiological processes. Prior research highlights this issue and demonstrates how a balancing of system gain and response time parameters causes linearV˙O2responses during ramp tests. This study builds upon this knowledge and extracts the time-varying dynamics directly from HR andV˙O2data of single ramp incremental running tests.

A prospective randomized study comparing two frameless immobilization systems for cranial stereotactic radiotherapy.

Introduction: The Dual Shell Encompass Fibreplast™ System (DS-Encompass) by CQ Medical™ is validated for frameless immobilization in stereotactic brain radiotherapy. An alternative mask model has been proposed with the rear shell replaced by a Moldcare® cushion (M-Encompass). To validate the use of this model in our cranial stereotactic workflow method including HyperArc™, we performed a prospective randomized study comparing inter-and intrafractional motion and patients comfort between both masks.

Chordoid Glioma as a Differential Diagnosis of Anterior Third Ventricle Tumours: A Rare Case Report and Five-Year Follow-Up.

Chordoid glioma is a rare and relatively recently defined tumour entity. Worldwide there have only been around 90 cases described until now. A chordoid glioma comprises a low-grade suprasellar neuroepithelial neoplasm originating in the anterior part of the third ventricle, with consistent radiological features on MRI.

Fungal Bezoars Mimicking an Enterovesica Fistula: A Unique Case Report.

Fungal colonization or infection of the urinary tract system is relatively common in patients with diabetes or a compromised immune system. However, fungal intravesical bezoars are extremely rare. We present a unique case with multiple, gas-holding fungals bezoars and emphysematous cystitis caused by

Indications and diagnostic yield of endomyocardial biopsies for unexplained cardiomyopathy, a single center experience.

Endomyocardial biopsies (EMBs) remain the golden standard to diagnose underlying pathophysiologic process in heart failure (HF), when potential therapeutic decisions cannot be made by non-invasive techniques. However, changes in the field of non-invasive diagnostic testing might have an impact on the need for performing an EMB in certain scenarios. We performed a retrospective analysis of consecutive EMBs performed in a single, non-academic, tertiary-care centre.
