Point-of-Care Capillary Blood Creatinine: A Prospective study in Cardiology and Nephrology Outpatients.

Background: The radiological or interventional use of contrast medium exposes patients to a risk of contrast-induced nephropathy. Pre-existing kidney failure is a major risk factor. Point-of-Care Capillary blood creatinine tests are promising; their speed might help to optimize treatment decisions and patient care in these situations.

Paradoxical worsening of hypoxemia in a patient treated by noninvasive positive pressure ventilation for obesity hypoventilation syndrome with concomitant obstructive sleep apnea: a case report.

Background: Noninvasive positive pressure ventilation is frequently prescribed to obese patients with obstructive sleep apnea syndrome and obesity hypoventilation syndrome. However, mechanical ventilation with a positive end-expiratory pressure can induce or worsen a right-to-left shunt through a patent foramen ovale associated with systemic hypoxemia. Thus, in obese patients treated with noninvasive positive pressure ventilation, a paradoxical worsening of hypoxemia may reveal the existence of a patent foramen ovale.

[Cardio-vascular assessment before starting to exercise after the age of 70].

Taking care of an elderly patient involves encouraging them to do some exercise. Ageing is responsible for a gradual loss of our capacity to adapt. Taking up a sport after the age of 70 must be done gradually and be preceded by a certain number of medical examinations, in particular an assessment of cardiac function.

Incidence, Characteristics, Risk Factors, and Outcomes of Takotsubo Cardiomyopathy With and Without Ventricular Arrhythmia.

Takotsubo cardiomyopathy (TC) is a medical entity mimicking an acute coronary syndrome (ACS). Ventricular arrhythmia (VA) in TC has been reported in small studies, leading to uncertain knowledge of its incidence. We sought to describe the characteristics, incidence, predictive factors, and outcomes of VA in patients presenting with TC.
