Exhumed eo‐Alpine High‐Pressure Rocks Fed Campanian Turbidites in Eastern Sardinia

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract This study investigates the detrital record of the early orogenic evolution of the Sardinia‐Calabria system, preserved in Upper Cretaceous arenites exposed in eastern Sardinia. Sardinia and Corsica form a continental block that includes a segment of the Alpine orogen and of its former foreland basin.

Dexamethasone Versus Placebo in Comatose Survivors of Out‐of‐Hospital Cardiac Arrest: Study Protocol for a Multicenter Randomized Comparison Within the Danish Out‐of‐Hospital Cardiac Arrest Trial (DANOHCA)

open access: yesActa Anaesthesiologica Scandinavica, Volume 70, Issue 7, August 2026.
ABSTRACT Background The inflammatory response to whole‐body ischemia, as seen in comatose survivors after out‐of‐hospital cardiac arrest (OHCA), is associated with increased morbidity and mortality. Early high‐dose dexamethasone may dampen the inflammatory response, which may diminish secondary brain damage and other organ injury and decrease mortality.

Hypocalcemia-Induced QT Interval Prolongation

Cardiology, 2022
An 87-year-old man with a history of transcatheter aortic valve replacement, pulmonary hypertension, diastolic dysfunction with preserved systolic function, and myelofibrosis had a 12-lead ECG showed a prolonged QT interval of 508 ms with heart-rate correction placing it in the 99th percentile of the population.

QT interval prolongation

The Journal of Emergency Medicine, 1985
The QT interval is a function of ventricular repolarization time and is measured from the onset of the QRS complex to the end of the T wave. The length of this interval is inversely related to heart rate. A prolonged QT interval is most often secondary to the use of Type I antidysrhythmic medications (quinidine, procainamide).

Syncope With Prolonged QT Interval

Archives of Pediatrics & Adolescent Medicine, 1976
Four children with syncope had a prolonged QT interval on the electrocardiogram. Neurologic studies were negative. One patient had associated deaf mutism, one had a family history of sudden death and prolonged QT interval, and two had ventricular arrhythmias while being monitored in the hospital.

Gatifloxacin and Prolonged QT Interval

The American Journal of the Medical Sciences, 2004
We report the case of a 54-year-old woman who, while being treated for acute sinusitis with gatifloxacin, presented with syncope and was found to have a markedly prolonged QT interval. After stopping gatifloxacin, the QT interval normalized. We speculate that her episode of syncope was caused by a ventricular arrhythmia that resulted from an increased ...

Prolongation of the QT interval in primary aldosteronism

Clinical and Experimental Pharmacology and Physiology, 2005
SUMMARY1. Only limited information is available concerning the changes in the electrocardiogram in primary aldosteronism. The aim of the present study was to determine factors influencing the QTc interval in patients with primary aldosteronism.2. Nineteen patients with primary aldosteronism caused by a Conn's adenoma and 69 patients with essential ...

Antipsychotic Drugs and QT Interval Prolongation

Psychiatric Quarterly, 2003
The QTc prolongation by antipsychotic drugs is of major concern, especially in light of the data indicating an increased risk of sudden death in psychiatric patients taking these drugs. Sudden death in psychiatric patients could be partially attributed to drug-induced torsades de pointes and for this reason careful evaluation of QTc prolonging ...

Prolonged QT-Interval Syndromes

JAMA: The Journal of the American Medical Association, 1986
PROLONGATION of the QT interval, either on a congenital or an acquired basis, is associated with an increased likelihood of malignant ventricular arrhythmias. 1-3 Patients with QT prolongation frequently develop recurrent attacks of syncope or may present with sudden death.
