Prediction of plasma volume and total hemoglobin mass with machine learning [PDF]

Physiological Reports, 2023
Hemoglobin concentration ([Hb]) is used for the clinical diagnosis of anemia, and in sports as a marker of blood doping. [Hb] is however subject to significant variations mainly due to shifts in plasma volume (PV).

Can Plasma Volume Determination in Cirrhosis Be Replaced by an Algorithm Using Body Weight and Hematocrit? [PDF]

Diagnostics
Background: Patients with cirrhosis often develop hyperdynamic circulation with increased cardiac output, heart rate, and redistribution of the circulating volume with expanded plasma volume (PV).

The influence of exercise volume and posture on exercise‐induced plasma volume expansion [PDF]

Physiological Reports, 2023
Acute high‐intensity interval exercise is known to expand plasma volume 24 h after exercise. Upright exercise posture plays a role in expanding plasma volume by influencing lymphatic outflow and redistributing albumin while supine exercise does not.

The Role of the Estimated Plasma Volume Variation in Assessing Decongestion in Patients with Acute Decompensated Heart Failure [PDF]

Biomedicines
Introduction and Aim: Assessing decongestion in patients with acute decompensated heart failure (ADHF) is challenging, requiring multiple parameters and often remaining imprecise. The study aimed to investigate the utility of indirectly estimating plasma

Sodium–Glucose Cotransporter 2 Inhibitor Combined with Conventional Diuretics Ameliorate Body Fluid Retention without Excessive Plasma Volume Reduction [PDF]

Diagnostics
We previously reported that sodium–glucose cotransporter 2 (SGLT2) inhibitors exert sustained fluid homeostatic actions through compensatory increases in osmotic diuresis-induced vasopressin secretion and fluid intake.

Hemoglobin Mass and Blood Volume in Patients With Altitude-Related Polycythemia

Frontiers in Physiology, 2022
Patients with chronic mountain sickness (CMS) have a high hemoglobin concentration [Hb] due to increased hemoglobin mass (Hbmass) and possibly reduced plasma volume (PV). The values of Hbmass, PV and blood volume (BV) have been described differently, and

Estimated plasma volume status can help identify patients with sepsis at risk of death within 30 days in the emergency department

Emergency Care Journal, 2023
For patients with sepsis in the Emergency Department (ED), early risk stratification is important to improve prognosis. The study aimed to evaluate the predictive role of estimated plasma volume (ePVS) on admission to the ED.

Native T1 is predictive of cardiovascular death/heart failure events and all-cause mortality irrespective of the patient’s volume status

Frontiers in Cardiovascular Medicine, 2023
BackgroundNative T1 has become a pivotal parameter of tissue composition that is assessed by cardiac magnetic resonance (CMR). It characterizes diseased myocardium and can be used for prognosis estimation. Recent publications have shown that native T1 is

The Efficacy of Heat Acclimatization Pre-World Cup in Female Soccer Players

Frontiers in Sports and Active Living, 2021
The efficacy of a 14-day field-based heat acclimatization (HA) training camp in 16 international female soccer players was investigated over three phases: phase 1: 8 days moderate HA (22.

Low Plasma Volume and Increased Pressure Load Relate to Concentric Left Ventricular Remodeling After Preeclampsia: A Longitudinal Study

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background During uncomplicated pregnancy, left ventricular remodeling occurs in an eccentric way. In contrast, during preeclamptic gestation, the left ventricle hypertrophies concentrically, concurrent with loss in circulatory volume and increased blood
