OBJECTIVE To evaluate efficacy of the recently introduced implantable loop recorder (ILR) in establishing symptom-rhythm correlation in young patients with syncope, near syncope, palpitations, and acute life-threatening events (ALTEs). METHODS A retrospective study was conducted with patients with ILR from 3 pediatric centers. Inclusion criteria were age <or=25 years and a minimum follow-up o...

BACKGROUND To estimate the short- and long-term financial impact of early referral for implantable loop recorder diagnostic (ILR) versus conventional diagnostic pathway (CDP) in the management of unexplained syncope (US) in the Portuguese National Health Service (PNHS). METHODS A Markov model was developed to estimate the expected number of hospital admissions due to US and its respective fin...

Assessment of the aetiology of syncope in children can be challenging. In the majority of cases, the cause can be determined from a careful personal and family history, and physical examination. Additional testing such as an ECG, stress test, Holter monitoring and echocardiogram are useful in helping to ferret out the aetiology of syncope. Tilt table testing is also occasionally considered in p...

As a consequence of improved S/N, spectral resolution and wavelength coverage various authors have introduced, without strong justification, new emitting regions to account for various emission line profile differences in AGN. The so-called CIVλ1549 intermediate line region (ILR) appears to be especially ill-defined. We present observational evidence that suggests the ILR is statistically indis...

In a widely cited 1995 paper, Aaron Yelowitz concluded that Medicaid eligibility expansions for children were associated with increased labor force participation and reduced welfare participation among single mothers. The authors of the present study, using data from the 1988–96 Current Population Surveys, reexamine the evidence presented by Yelowitz. They find that Yelowitz's results resulted ...

An implantable loop recorder (ILR) was implanted in a 45 year old man with recurrent syncope. A subsequent episode of injurious syncope led to performance of a cranial and shoulder magnetic resonance imaging (MRI). An artefact mimicking both wide and narrow complex tachycardias was recorded by the ILR during the shoulder MRI but not the cranial MRI. Caution should be used when interpreting the ...

AIM An implantable loop recorder (ILR) is indicated in patients with unexplained syncope after complete conventional work-up. Data from the literature imply that, in clinical practice, the ILR is underused. The aim of the study was to verify if there is any discrepancy between the use of ILRs in clinical practice and the potential indications based on the most potentially appropriate guideline ...

Statistical investigations of samples of quasars have established that clusters of properties are correlated. The strongest trends among the ultraviolet emission-line properties are characterized by the object-to-object variation of emission from low-velocity gas, the so-called \intermediate-line region" or ILR. The strongest trends among the optical emission-line properties are characterized b...

Abstract. Many practical data sets in environmental sciences, official statistics and various other disciplines are in fact compositional data because only the ratios between the variables are informative. Compositional data are represented in the Aitchison geometry on the simplex, and for applying statistical methods designed for the Euclidean geometry they need to be transformed first. The is...
