BACKGROUND The initial diagnosis of ectopic pregnancy depends on physical examination, ultrasound, and serial measurements of total β-subunit of human chorionic gonadotropin (hCGβ) concentrations in serum. The aim of this study was to explore the possibility of using quantitative analysis of total hCGβ in urine rather than in serum by immunomagnetic reduction (IMR) assay as an alternative metho...

BACKGROUND Dilatation of the rectum and/or colon, in the absence of demonstrable organic disease, is an uncommon and poorly characterised condition. AIMS To characterise the clinical and diagnostic features, and response to treatment, of patients with idiopathic megarectum (IMR) and idiopathic megacolon (IMC). METHODS A retrospective review was undertaken of all patients operated on for the...

BACKGROUND The persistence of moderate ischemic mitral regurgitation (IMR) after isolated coronary artery bypass graft surgery is an important independent predictor of long-term mortality. The aim of the present study was to identify predictors of postoperative improvement in moderate IMR in patients with ischemic heart disease undergoing elective isolated coronary artery bypass graft surgery. ...

BACKGROUND/AIMS The aim of this study was to elucidate the effects of glucose restriction (GR) on cell replicative senescence in vitro by human diploid fibroblasts IMR-90. METHODS IMR-90 cells were cultured under 40, 60% GR or high glucose medium and biomarkers of cell senescence were compared with cells cultured in normal glucose medium (5.5 mM glucose). The impact of different concentration...

Ischemic mitral regurgitation (IMR) is a relatively frequent complication of myocardial infarction. The presence of IMR negatively influences imminent mortality after myocardial infarction and the long-term survival of the patients. IMR is a functional, not morphological impairment of mitral valve and is caused by a change in the geometry of the left ventricle. In the review article, the author...

OBJECTIVES We assessed the value of Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) services as a public health intervention seeking to improve birth outcomes and reduce racial disparities. METHODS We compared the infant mortality rate (IMR) per 1000 live births and percentage of preterm births overall and by race for prenatal WIC versus non-WIC participants in H...

The usefulness of 1.5-T high-field intraoperative magnetic resonance (iMR) imaging during transsphenoidal surgery for functioning pituitary adenomas was retrospectively evaluated based on long-term endocrine remission from the records of 14 patients who underwent transsphenoidal surgery with iMR imaging for functioning pituitary microadenomas and small adenomas located in the intrasellar region...

INTRODUCTION Given its location on the Andes, the Northwest region of Argentina is geographically, socioeconomically, culturally, and biologically heterogeneous, and this is reflected on an infant mortality rate (IMR) that is higher than in any other Argentine region. OBJETIVE To estimate IMR, neonatal mortality rate (NMR), and post-neonatal mortality rate (PNMR), and to analyze their spatial...
