Assessment of volemia status using ultrasound examination of the inferior vena cava and spectroscopic bioimpendance in hemodialysis patients [PDF]
Vojnosanitetski Pregled, 2022 Background/Aim. Hypervolemia is an important risk factor for the development of cardiovascular morbidity and mortality in patients treated with regular hemodialysis. There is still no reliable method for assessing the status of volemia in these patients.

European Journal of Heart Failure, 2019 Plasma volume expansion is clinically and prognostically relevant in individuals with heart failure. Prior cohorts either excluded or had limited representation of patients with heart failure with preserved ejection fraction (HFpEF).

Critical Care, 2019 BackgroundOptimal infusion rate of colloids in patients with suspected hypovolemia is unknown, and the primary objective of the present study was to test if plasma volume expansion by 5% albumin is greater if fluid is administered slowly rather than ...

Theoretical aspect of enhancement and saturation in emission from laser produced plasma [PDF]
Laser and Particle beam (30) 621 (2012), 2014 This paper presents a simplified theoretical model for the study of emission from laser produced plasma to better understand the processes and the factors involved in the onset of saturation in plasma emission as well as in increasing emission due to plasma confinement. This model considers that plasma emission is directly proportional to the square of

Global Heart, 2022 Background: Plasma volume (PV) expansion hallmarks the syndrome of heart failure (HF) but is difficult to be quantified noninvasively. Estimated plasma volume status (ePVS) has marked prognostic utility in the failing left heart, however its use in right

Haematologica, 2017 In practice, clinicians generally consider anemia (circulating hemoglobin concentration < 120 g.l−1 in non-pregnant females and < 130 g.l−1 in males) as due to impaired hemoglobin synthesis or increased erythrocyte loss or destruction.

Physiological Reports, 2023 Introduction Consuming intracellular osmolytes, like betaine (BET), may attenuate symptoms of heat stress. The purpose of this study was to examine the effects of BET supplementation on fluid balance and heat tolerance after a 7‐day loading period and ...

Emerging understanding and measurement of plasma volume expansion in pregnancy.
American Journal of Clinical Nutrition, 2017 Plasma volume expansion is an important component of a successful pregnancy. The failure of maternal plasma volume expansion has been implicated in adverse obstetric outcomes such as pre-eclampsia, fetal growth restriction, and preterm birth.

AJP - Renal Physiology, 2016 Pregnancy is characterized by avid renal sodium retention and plasma volume expansion in the presence of decreased blood pressure. Decreased maternal blood pressure is a consequence of reduced systemic vascular tone, which results from an increased ...

Physiological Reports, 2022 Changes in hydration status influence plasma volume (PV) which is associated with post‐exercise parasympathetic reactivation. The present study hypothesized that, after dehydrating cycling exercise in the heat (DE), stimulation of PV expansion with ...
