Among athletes strenuous exercise, dehydration and gastric emptying (GE) delay are the main causes of gastrointestinal (GI) complaints, whereas gut ischemia is the main cause of their nausea, vomiting, abdominal pain and (blood) diarrhea. Additionally any factor that limits sweat evaporation, such as a hot and humid environment and/or body dehydration, has profound effects on muscle glycogen de...

Access to interstitial fluid from trachea is important for understanding tracheal microcirculation and pathophysiology. We tested whether a centrifugation method could be applied to isolate this fluid in rats by exposing excised trachea to G forces up to 609 g. The ratio between the concentration of the equilibrated extracellular tracer 51Cr-labeled EDTA in fluid isolated at 239 g and plasma av...

BACKGROUND Evaluation of patient's dry weight remains challenging in chronic hemodialysis (HD) especially in children. Inferior Vena Cava (IVC) measurement was reported useful to assess fluid overload both in adults and children. METHODS We performed a monocentric prospective study to evaluate the relation between predialytic IVC diameter measurements and hydration status evaluated by physici...

OBJECTIVE Dysnatremia and altered hydration status are potentially serious conditions that have not been well studied in multistage ultramarathons. The purpose of this study was to assess the incidence and prevalence of exercise-associated hyponatremia (EAH) (Na+ <135 mmol·L-1) and hypernatremia (Na+ >145 mmol·L-1) and hydration status during a multistage ultramarathon. METHODS This study inv...

Abstract Background and Aims There is a clear relationship between volume overload morbidity mortality in hemodialysis patients, which makes it essential to accurately adjust the normohydrated weight. For this, bioimpedance has become an indispensable tool dialysis units. In recent years there been rapid development of lung ultrasound for evaluation pulmonary congestion through quantification B...

Abstract Background and Aims Assessment of fluid status in hemodialysis patients (HD) remains a major challenge for nephrologists. Fluid overload is one the most common modifiable risk factors directly associated with hypertension. The purpose our study was to investigate whether combination three bedside methods-lung ultrasound comets (LUC), multifrequency bioimpedance (MBIS), inferior vena ca...

Abstract Background and Aims Inadequate fluid sodium removal has been shown to increase risk of overhydration hypertension. In peritoneal dialysis, icodextrin-based solution provides sustained ultrafiltration, therefore can be used for the long exchanges, especially in patients with fast solute transport rates whom effective ultrafiltration period is shortened. We investigated which extent effi...

The submandibular gland transports fluid at a high rate through the interstitial space during salivation, but the exact level of all forces governing transcapillary fluid transport has not been established. In this study, our aim was to measure the relation between interstitial fluid volume (V(i)) and interstitial fluid pressure (P(if)) in salivary glands during active secretion and after syste...

INTRODUCTION Computed tomography is commonly used to exclude occult injuries in patients with trauma, but imaging can reveal findings that are of uncertain etiology or clinical significance. We present a case of unsuspected pancreatic abnormality in a female patient with trauma who sustained an isolated blunt head injury. CASE PRESENTATION A 25-year-old female Caucasian patient sustained mass...
