The constructive interference in steady state (CISS) sequence has been widely used in human neuroimaging. It has been shown to be advantageous in the evaluation of intra-axial and extra-axial cystic abnormalities, arteriovenous and dysraphic malformations and disturbances of cerebrospinal fluid circulation. To assess the utility of this technique in small animals, interpretations based on this sequence were compared with those based on T2-weighted (T2W) sequences in 145 dogs that underwent MRI of the spine for suspected spinal cord disease...

PURPOSE OF REVIEW: The essential role of the lymphatic system in fluid homeostasis, nutrient transport, and immune trafficking is well recognized; however, there is limited understanding of the mechanisms that regulate lymphatic function, particularly in the setting of critical illness. The lymphatics likely affect disease severity and progression in every condition, from severe systemic inflammatory states to respiratory failure. Here, we review structural and functional disorders of the lymphatic system, both congenital and acquired, as they relate to care of the pediatric patient in the intensive care setting, including novel areas of research into medical and procedural therapeutic interventions...

BACKGROUND: Therapeutic plasma exchange (TPE) is an extracorporeal procedure which consists of removing the patient's plasma and replacing it with an appropriate replacement fluid. Plasma and blood cells are separated by a centrifugation process. Our department has used TPE for several years, and in 2013 we introduced an institutional apheresis protocol. The main objective of this report is to describe the TPE procedures performed between 2013 and 2016 in the Peruvian population. METHODS: We analyzed the technical and clinical aspects of 864 centrifugal TPE procedures as well as the associated complications...

The aim of this study was to investigate the methane (CH4) reducing potential of a combination of pre- and/or postnatal treatment with coconut oil medium chain fatty acids (CO MCFA) in goat kids. The hypothesis is that influencing rumen function during early life has more chances for success than in the adult life, related to the resilience of the mature rumen microbiota. Forty-eight pregnant does were split into 2 experimental groups: treated does (D+) received 40 g/d of CO MCFA in a test compound feed, while control does (D-) received a control compound feed, during the last 3 wk of gestation...

NEW FINDINGS: What is the central question of this study? Collagen-binding β1 -integrins function physiologically in cellular control of dermal interstitial fluid pressure (PIF ) in vivo and thereby participate in control of extravascular fluid volume. During anaphylaxis, simulated by injection of Compound 48/80 integrin αV β3 takes over this physiological function. Here we addressed the question whether integrin αV β3 can replace collagen-binding β1 -integrin to maintain a long-term homeostatic PIF ...

The limited availability of metabolite-specific sensors for continuous sampling and monitoring is one of the main bottlenecks contributing to failures in bioprocess development. Furthermore, only a limited number of approaches exist to connect currently available measurement systems with high throughput reactor units. This is especially relevant in the biocatalyst screening and characterization stage of process development. In this work, a strategy for sensor integration in microfluidic platforms is demonstrated, to address the need for rapid, cost-effective and high-throughput screening in bioprocesses...

Mesenchymal stem cells (MSCs) have generated great interest in the fields of regenerative medicine and immunotherapy because of their unique biological properties. Among MSCs, amniotic fluid stem cells (AFS) have a number of characteristics that make them attractive candidates for tissue engineering and cell replacement strategies, particularly for perinatal medicine. If various neonatal conditions, including birth asphyxia, preterm birth, and congenital abnormalities, which result in long-lasting severe impairments, could be predicted during pregnancy, it would allow collection of small samples of amniotic fluid cells by amniocentesis...

Osmotic diuresis results from urine loss of large amounts of solutes distributed either in total body water or in the extracellular compartment. Replacement solutions should reflect the volume and monovalent cation (sodium and potassium) content of the fluid lost. Whereas the volume of the solutions used to replace losses that occurred prior to the diagnosis of osmotic diuresis is guided by the clinical picture, the composition of these solutions is predicated on serum sodium concentration and urinary sodium and potassium concentrations at presentation...

Hemodiafiltration combines diffusive and convective solute removal in a single therapy by ultrafiltering 20% or more of the blood volume processed using a high-flux hemodialyzer and maintaining fluid balance by infusing sterile nonpyrogenic replacement fluid directly into the patient's blood. In online hemodiafiltration, the large volumes of replacement fluid required are obtained by online filtration of standard dialysate through a series of bacteria- and endotoxin-retaining filters. Currently available systems for online hemodiafiltration are on the basis of conventional dialysis machines with added features to safely prepare and infuse replacement fluid and closely control fluid balance...

PURPOSE: Hematopoietic cell transplant (HCT) recipients often require intravenous (IV) magnesium repletion due to poor dietary intake, gastrointestinal loss, and use of concomitant magnesium wasting medications. Prolonging the IV magnesium infusion rate has been postulated to reduce renal clearance and improve retention; however, limited evidence supports this hypothesis. METHODS: We reviewed autologous and allogeneic HCT recipients (n = 82) who received IV magnesium at our institution between 2014 and 2016: 41 patients received IV magnesium at a prolonged rate of 0...

BACKGROUND: Sick newborn and preterm infants frequently are not able to be fed enterally, necessitating parenteral fluid and nutrition. Potential benefits of higher parenteral amino acid (AA) intake for improved nitrogen balance, growth, and infant health may be outweighed by the infant's ability to utilise high intake of parenteral AA, especially in the days after birth. OBJECTIVES: The primary objective is to determine whether higher versus lower intake of parenteral AA is associated with improved growth and disability-free survival in newborn infants receiving parenteral nutrition...

INTRODUCTION: The debate on replacing coagulation factors and its effect on the final outcome of the patients with acute traumatic coagulopathy (ATC) in need of transfusion is still ongoing. Therefore, the present study is designed with the aim of comparing the outcome of patients with acute traumatic coagulopathies receiving fibrinogen and fresh frozen plasma (FFP). METHODS: In this quasi-experimental randomized controlled study, patients with severe blunt trauma (ISS>16) and in need of packed cells transfusion were divided into 3 groups of receiving fibrinogen, receiving FFP, and control, and their final outcome was compared...

BACKGROUND: The risk of fluid overload and mortality is increased in patients with severe acute kidney injury. Charting of daily fluid balance is a key component of fluid assessment but not without problems affecting accuracy. The introduction of electronic bed scales has made routine patient-weighing easier and focused attention on monitoring fluid-related weight changes. OBJECTIVES: This paper investigated the frequency of compliance in weighing patients daily using electronic bed scales and evaluated the relationship between calculated fluid balance and body weight changes in patients receiving continuous renal replacement therapy (CRRT)...

Diseases of the cardiovascular system account for nearly 42% of all deaths in the European Union. In Germany, approximately 12,000 patients receive surgical replacement of the aortic valve due to heart valve disease alone each year. A three-dimensional (3D) numerical model based on patient-specific anatomy derived from four-dimensional (4D) magnetic resonance imaging (MRI) data was developed to investigate preoperatively the flow-induced impact of mounting positions of aortic prosthetic valves to select the best orientation for individual patients...

RATIONALE: A 35-year old Chinese female was admitted to hospital with refractory pericardial effusions 10 days post mitral valve replacement via median sternotomy. We performed an exploratory resternotomy and found lymphatic leakage on the surface of the diaphragm which was continuously emitting a light yellow fluid. PATIENT CONCERNS: The patient complained of no obvious discomfort except for the concern of massive pericardial effusion drainage. DIAGNOSES: Exploratory resternotomy and biochemical testing lead to a supradiaphragmatic lymphatic fistula being diagnosed as the cause of the refractory pericardial effusion...

BACKGROUND: The structured breast implant utilizes different technology than saline or silicone gel implants, making it a third type of implant. FDA and Health Canada granted approval in November 2014.This implant is filled with saline, but has an internal structure consisting of a series of nested shells that support the upper pole when upright and control fluid movement. It combines certain key features and benefits of saline and silicone gel implants. Like saline, the filler is only saline, which women like for peace of mind in case of rupture/deflation...
