OBJECTIVE To investigate haemorheological changes during pregnancy in a Latin American population and compare to previously published data from Caucasian populations. DESIGN Cross-sectional study. POPULATION 75 pregnant women at 10-36 wk of gestation and 17 non-pregnant female controls in Lima, Peru. All the women and their ancestors for three generations were born and lived at sea level. ...

An increase in blood viscosity and haematocrit, and a decrease in plasma volume, have been shown to follow stimulation of the sympathetic nervous system, as associated with, for example, severe exercise, emotional excitement or the administration of some sympathomimetic amines (Kaltreider and Meneely, 1940; Kaltreider, Meneely and Allen, 1942; Conn, 1966). It is to be expected that a depression...

Sex variations in some haemorheological parameters: Haematocrit (Hct), Erythrocyte Sedimentation Rate (ESR), Hemoglobin concentration (Hbc), Fibrinogen concentration (FC), Relative Plasma Viscosity (RPV) and Whole Blood Relative Viscosity (WBRV) were determined in 30 male and 20 female hypertensive subjects without complications, aged between 30 and 70 years. 30 male and 20 female normotensive ...

Although wet cupping is quite a popular procedure that is practised worldwide, there is not enough evidence that it may cause anaemia as a side effect. In this observational retrospective pre–post study, we looked through the previously recorded data of patients who received wet cupping at King Abdulaziz University Hospital. We included in the study all those who had their complete blood count ...

Phenotypic correlations (rP) have frequently been observed between physiological and behavioural traits, and the nature of these associations has been shown to be modulated by a range of environmental stressors. Studies to date have examined the effects of acute stressors on physiology-behaviour interrelations, but the potential for permanent changes induced by exposure to stress during develop...

Objective: Patients who had curative treatment after a malignant disease frequently ask about their religious practices and especially Ramadan fasting. The aim of this study is to evaluate the survivors gastric cancer patients whether they keep fasting health conditions experienced during month Ramadan. Materials Methods: For cross sectional observational study, first files gastrectomy due mali...

Objectives To compare the traditional haematocrit-based criteria (>20% rise above baseline) with ultrasonography for diagnosing plasma leakage in dengue fever and to identify clinical indicators triaging patients resource-limited settings when demand is high. Methods The Colombo Dengue Study a prospective observational cohort study recruiting first three days of fever, before leakage. Serial ha...

Method We did a retrospective study on two groups of patients undergoing coronary artery bypass surgery over a six month period. In the non RAP group (n = 124), the CPB circuit was primed with crystalloid standard prime. In the RAP group (n = 120), retrograde autologous priming was used to reduce crystalloid prime (620.77 ml ± 133.13 ml). Haematocrit levels, transfusion requirements and other c...
