Mechanisms, Risk Factors, and Management of Acquired Long QT Syndrome: A Comprehensive Review

The Scientific World Journal, 2012
Long QT syndrome is characterized by prolongation of the corrected QT (QTc) interval on the surface electrocardiogram and is associated with precipitation of torsade de pointes (TdP), a polymorphic ventricular tachycardia that may cause sudden death ...

Magnetic nanoparticles‐decorated zeolite thin film derived from coal fly ash: Application to detoxification of para‐nitrophenol

Journal of the Chinese Chemical Society, EarlyView.
Magnetic zeolite films: Application for the detoxification of para‐nitrophenol. Abstract Fly ash, an industrial by‐product generated from coal combustion, poses significant environmental and health hazards. However, its remarkable adsorption behavior for various toxic pollutants can be further enhanced through physical and chemical modifications ...

Quantitative Confounder Analysis of Electrocardiogram Signals in Cardiac Magnetic Resonance at 1.5, 3 and 7 T—Assessing Standardized Electrode Positions and Sequence Types—Towards Quality Assurance

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background The electrocardiogram (ECG) used for gating in cardiac MRI may be compromised by multiple confounders inside the scanner bore. Purpose To quantify the influence of magnetic field strengths (1.5 T/3 T/7 T), standardized electrode positions, and imaging sequences on ECG signals used for gating. Study Type Prospective.

Multifactorial QT interval prolongation [PDF]

, 2010
Acquired long QT interval has been widely reported to be a consequence of drug therapy and electrolyte disturbances. We describe two cases of multifactorial acquired QT interval prolongation and torsades de pointes.

Sonographic Patellar and Quadriceps Tendon Length Pre‐ and Post‐Autograft Harvest: Reliability and Concurrent Validity

Journal of Orthopaedic Research, EarlyView.
ABSTRACT Extensor mechanism autografts used for anterior cruciate ligament reconstruction, namely bone‐patellar tendon‐bone (BPTB) and quadriceps tendon (QT), may result in harvest‐site tendon elongation. Extended field of view (EFOV) ultrasound imaging has the potential to evaluate changes in tendon length, but the reliability and validity of these ...

Propranolol can correct prolonged QT intervals in patients with cirrhosis

Frontiers in Pharmacology
Background:Prolonged QT intervals are extremely common in patients with cirrhosis and affect their treatment outcomes. Propranolol is often used to prevent gastroesophageal variceal hemorrhage in patients with cirrhosis; however, it is uncertain whether ...

Quadriceps, hamstring and patella tendon autografts for primary anterior cruciate ligament reconstruction demonstrate similar clinical outcomes, including graft failure, joint laxity and complications: A systematic review with meta‐analysis of randomised controlled trials

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Graft failure following anterior cruciate ligament reconstruction (ACLR) remains a significant challenge, driving discussion for optimal graft choice. Traditionally, hamstring tendon (HT) and bone‐patella tendon‐bone (BPTB) autografts have been favoured for ACLR. Recently, quadriceps tendon (QT) usage has increased.

Drug-Induced QT Prolongation as a Result of an Escitalopram Overdose in a Patient with Previously Undiagnosed Congenital Long QT Syndrome

Case Reports in Medicine, 2014
We present a case of drug-induced QT prolongation caused by an escitalopram overdose in a patient with previously undiagnosed congenital LQTS. A 15-year-old Caucasian female presented following a suicide attempt via an escitalopram overdose.

Various surgical techniques result in different outcomes for full extensor mechanism ruptures following total knee replacement: A systematic review by the European Knee Associates (ESSKA‐EKA)

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Extensor mechanism (EM) ruptures after total knee arthroplasty (TKA) are rare but lead to substantial functional impairment and morbidity. Treatment remains challenging due to the diversity of surgical techniques and the limited number of comparative studies.
