In utero or early-life vitamin D deficiency is associated with skeletal problems, type 1 diabetes, and schizophrenia, but the prevalence of vitamin D deficiency in U.S. pregnant women is unexplored. We sought to assess vitamin D status of pregnant women and their neonates residing in Pittsburgh by race and season. Serum 25-hydroxyvitamin D (25(OH)D) was(More)
This paper describes a computer-assisted non-existence proof of 9-input sorting networks consisting of 24 comparators, hence showing that the 25-comparator sorting network found by Floyd in 1964 is optimal. As a corollary, we obtain that the 29-comparator network found by Waksman in 1969 is optimal when sorting 10 inputs. This closes the two smallest open(More)
The Ehlers-Danlos syndromes (EDS) are a clinically and genetically heterogeneous group of heritable connective tissue disorders (HCTDs) characterized by joint hypermobility, skin hyperextensibility, and tissue fragility. Over the past two decades, the Villefranche Nosology, which delineated six subtypes, has been widely used as the standard for clinical(More)
INTRODUCTION Aortic aneurysms are a well known but rare complication of tuberculosis. Their major complication is aneurysmal rupture, unforeseeable and lethal. EXEGESIS Chest pain and hemoptoic expectoration revealed a false aneurysm of the aortic isthmus in a 48-year-old man. Endovascular repair with a stent graft was urgently undertaken.

OBJECTIVE We investigated changes in serum uric acid across pregnancy in women with gestational hyperuricemia at delivery, with and without preeclampsia, compared with normal pregnant and women with preeclampsia without gestational hyperuricemia. STUDY DESIGN This was a nested case-control study of 116 controls, 27 women with preeclampsia with predelivery(More)
PURPOSE The aim of this prospective randomized study was to evaluate the clinical outcome of immediately loaded solid plasma sprayed (TPS) BioComp (BioComp Industries BV, Vught, The Netherlands) implants versus immediate provisionalized but non-loaded BioComp implants in the anterior and premolar region of the maxilla. MATERIALS AND METHODS Forty-eight(More)
CONTEXT Apelin and vasopressin levels are regulated in opposite directions to maintain body fluid homeostasis. OBJECTIVE We thus assessed plasma apelin to copeptin ratios, with plasma copeptin concentrations as a reliable index of vasopressin secretion, in pathological states combining high levels of vasopressin secretion with hyponatremia. DESIGN,(More)
