OBJECTIVE The purpose of this study was to provide a viable alternative to routine postpartum hematocrit measurement, by a determination of the clinical risk factors that identify patients with anemia and an examination of the resulting cost savings. STUDY DESIGN In this retrospective review, cases (postpartum hematocrit level, <26%; subgroup hematocrit level, <23%) and control subjects were ...

A population-based study of the relation between hematocrit and stroke subtype was carried out among 2,077 individuals using the Lehigh Valley Stroke Register. This register identifies all stroke patients admitted to the 8 acute care hospitals serving the Lehigh Valley area of eastern Pennsylvania-western New Jersey. The mean hematocrit was higher in patients with lacunes than with thrombotic o...

This study compared the effects on the kidney of two major determinants of blood viscosity, the hematocrit and the plasma colloid content. In anesthetized dogs, blood viscosity was raised 30% by increasing hematocrit or infusing isoncotic Dextran 500 while blood volume was kept constant. Neither form of hyperviscosity altered blood pressure, but both forms caused a decrease of about 35% in card...

OBJECTIVE Previous work has found cerebral oxygen extraction to decrease during hypothermic cardiopulmonary bypass in children. To elucidate cardiopulmonary bypass factors controlling cerebral oxygen extraction, we examined the effect of perfusate temperature, pump flow rate, and hematocrit value on cerebral hemoglobin-oxygen saturation as measured by near infrared spectroscopy. METHODS Forty...

The cortical hem, a source of Wingless-related (WNT) and bone morphogenetic protein (BMP) signaling in the dorsomedial telencephalon, is the embryonic organizer for the hippocampus. Whether the hem is a major regulator of cortical patterning outside the hippocampus has not been investigated. We examined regional organization across the entire cerebral cortex in mice genetically engineered to la...

OBJECTIVE To investigate whether breastfeeding in early life affects blood pressure of preschoolers. METHODS Cross-sectional study nested in a cohort from a municipality in the state of Minas Gerais, Brazil. All children in the cohort were invited for this study. Thus, between 2009 and 2010, blood pressure of 230 preschool children and their mothers, in addition to anthropometric variables, p...

The study was conducted at the department of Obstetrics and Gynecology at Jawaharlal Nehru Medical College, Aligarh India from June 2008 to October 2010. 200 mothers were selected for the study and informed consent using a predesigned proforma. The subjects were divided into 4 groups of 50 each wherein the umbilical cord was clamped at 15 seconds, 30 seconds, 1 minute and 2 minutes respectively...

Maternal mortality due to postpartum hemorrhage (PPH) continues to be one of the most important causes of maternal death worldwide. PPH is a significantly underestimated obstetric problem, primarily because a lack of definition and diagnosis. The 'traditional' definition of primary PPH based on quantification of blood loss has several limitations. Notoriously, blood loss is not measured or is s...
