OBJECTIVES This retrospective study was performed to provide data on ventricular tachycardias (VT) with a cycle length longer than the initially programmed tachycardia detection interval (TDI) in patients with implantable cardioverter defibrillators (ICDs). BACKGROUND It has been clinical practice to program a safety margin of 30 to 60 ms between the slowest spontaneous or inducible VT and th...

OBJECTIVES/HYPOTHESIS At many centers, ventilating tubes (VTs) are placed routinely in otitis-prone pediatric cochlear implant recipients. However, this practice is controversial, as many otologists believe VTs represent a possible route for contamination of the device. Toward better understanding of the safety of VTs, we reviewed our center's infectious complications and their relationship to ...

Cerebral venous thrombosis (CVT) covers up to a third of all venous thromboses (VTs) detected in patients with acute lymphoblastic leukemia (ALL). It usually hampers patients' lives and may also endanger efficient leukemia treatment. Although many factors have been suggested to account for an elevated risk of VTs in patients with ALL, there still is a lack of studies focusing on CVTs and especi...

A disintegrin and metalloproteinases (ADAMs) are members of the metzincin family of zinc-dependent metalloproteinases that play pivotal roles in the proteolytic degradation of the extracellular matrix for cell invasion. Few studies have investigated the ADAM subtypes that are expressed in first trimester trophoblast cells. The purpose of this study was to elucidate the differential expression p...

This paper is a research in progress. Virtual teams (VTs) are increasingly common in organizations, yet explicit research on VTs’ performance is relatively rare. One of the key challenges faced by individuals in VTs is the awareness of ‘who knows what’ and ‘who does what’ in the team. One of the solutions offered by past research in overcoming these key challenges is for teams to form Transacti...

The purpose of this study was to determine the relationship between visual tracking speed (VTS) and reaction time (RT) on basketball-specific measures of performance. Twelve professional basketball players were tested before the 2012-13 season. Visual tracking speed was obtained from 1 core session (20 trials) of the multiple object tracking test, whereas RT was measured by fixed- and variable-...

BACKGROUND ECG criteria identifying epicardial (EPI) origin for ventricular tachycardia (VT) in nonischemic cardiomyopathy have not been determined. Endocardial (ENDO) and EPI basal left ventricle fibrosis characterizes the VT substrate. METHODS AND RESULTS We assessed the QRS from 102 basal-superior/lateral EPI and 67 comparable ENDO pace maps in 14 patients with nonischemic cardiomyopathy. ...

BACKGROUND Information on pneumococcal serotype distribution before vaccination is a prerequisite for evaluation of vaccine effect. The aim was to investigate the prevalence of pneumococcal serotypes isolated from middle ear (ME), lower respiratory tract (LRT) and from invasive disease (IPD) in Iceland prior to implementation of ten-valent pneumococcal Haemophilus influenzae protein D conjugate...
