An audit of randomly selected case records of 810 patients admitted to 13 hospitals between December 2015 and November 2016 was done. Prevalence of dehydration was 19.7% (2293 of 11 636) [95% CI: 17.1-22.6%], range across hospitals was 9.4% to 27.0%. Most cases with dehydration were clinically diagnosed (82 of 153; 53.6%), followed by excessive weight loss (54 of 153; 35.3%) and abnormal urea/electrolytes/creatinine (23 of 153; 15.0%). Documentation of fluids prescribed was poor but, where data were available, Ringers lactate (30 of 153; 19...

OBJECTIVE: To observe the effect of transcutaneous acupoint electrical stimulation (TAES) on hemodynamic fluctuation caused by loosing tourniquet in the elderly patients undergoing knee joint replacement. METHODS: A total of 60 ASA (America Society Anesthesiologist) I or II elderly patients for elective knee joint replacement surgery were randomly divided into control group (30 cases) and TAES group (30 cases). Patients of both groups were treated by intravenous anesthesia, and monitored with bispectral index (BIS, between 45-60) for anesthesia depth, stroke volume variation (SVV) for fluid management, mean arterial pressure (MAP) and cardiac index (CI) for hemodynamic fluctuation evaluation, and with analgesia nociception index (ANI, between 50-70) for remifentanil dosage adjustment...

RATIONALE: The effects of fluid administration during acute asthma exacerbation are likely unique in this patient population: highly negative inspiratory intrapleural pressure resulting from increased airway resistance may interact with excess fluid administration to favor the accumulation of extravascular lung water, leading to worse clinical outcomes. OBJECTIVES: Investigate how fluid balance influences clinical outcomes in children hospitalized for asthma exacerbation...

OBJECTIVE: Ultrafiltration (UF) during cardiopulmonary bypass (CPB) is a well-accepted method for hemoconcentration to reduce excess fluid and increase hematocrit, platelet count and plasma constituents. The efficacy of this technique may confer specific benefit to certain patients presenting with acquired cardiac defects. The purpose of this study was to retrospectively evaluate the effect of UF on end-CPB hematocrit by cardiac surgical procedure type. METHODS: A review of 73,506 cardiac procedures from a national registry (SCOPE) was conducted between April 2012 and October 2016 at 197 institutions...

Objective: To investigate the clinical applicability of electrical velocimetry (EV) in monitoring pediatric blood volume after cardiopulmonary bypass. Method: Between July 2016 and November 2016, 60 children with congenital heart disease were divided into EV group and traditional central venous pressure (CVP) group randomly. For EV group, the volume of fluid and vascular active medicine was adjusted according to the monitoring stroke volume variation (SVV) hemodynamic parameters. Whereas for CVP group empirical volume of fluid infusion was managed by the monitoring traditional hemodynamic parameters such as CVP, blood pressure, heart rate, urine volume and blood gas analysis...

OBJECTIVE: Pediatric burn patients are more susceptible to burn shock than adults, and an effective fluid management protocol is critical to successful resuscitation. Our research aim was to investigate the safety and efficacy of two protocols for pediatric burn patients for use within the first 24h. METHODS: A total of 113 pediatric burn patients were enrolled from January 2007 to October 2012. Of those patients, 57 received fluid titration regimens of alternating crystalloids and colloids once within 2h in the first 24h after burn (Group A), whereas the remaining patients received regimens of alternating crystalloids and colloids once within 1h in the first 24h after burn (Group B)...

Beamformers are a widely-used tool in brain analysis with magnetoencephalography (MEG) and electroencephalography (EEG). For the construction of the beamformer filters realistic head volume conductor modeling is necessary for accurately computing the EEG and MEG leadfields, i.e., for solving the EEG and MEG forward problem. In this work, we investigate the influence of including realistic head tissue compartments into a finite element method (FEM) model on the beamformer's localization ability. Specifically, we investigate the effect of including cerebrospinal fluid, gray matter, and white matter distinction, as well as segmenting the skull bone into compacta and spongiosa, and modeling white matter anisotropy...

Severe sepsis and septic shock remain among the deadliest diseases managed in the intensive care unit. Fluid resuscitation has been a mainstay of early treatment, but the deleterious effects of excessive fluid administration leading to tissue edema are becoming clearer. A positive fluid balance at 72 hours is associated with significantly increased mortality, yet ongoing fluid administration beyond a durable increase in cardiac output is common. We review the pathophysiologic and clinical data showing the negative effects of edema on pulmonary, renal, central nervous, hepatic, and cardiovascular systems...

Brain swelling is a serious condition associated with an accumulation of fluid inside the brain that can be caused by trauma, stroke, infection, or tumors. It increases the pressure inside the skull and reduces blood and oxygen supply. To relieve the intracranial pressure, neurosurgeons remove part of the skull and allow the swollen brain to bulge outward, a procedure known as decompressive craniectomy. Decompressive craniectomy has been preformed for more than a century; yet, its effects on the swollen brain remain poorly understood...

The intervertebral disc viscoelastic response is governed primarily by its fluid content and flow. Invivo measurements demonstrate that the disc volume, fluid content, height and nucleus pressure completely recover during resting even after diurnal loading with twice longer duration (16 vs. 8 h). In view of much longer periods required for the recovery of disc height and pressure in vitro, concerns have been raised on the fluid inflow through the endplates that might be hampered by clogged blood vessels post mortem...

A 66-year-old Caucasian male became unconscious 2 weeks after initiation of add-on therapy with empagliflozin for poorly controlled type 2 diabetes mellitus. The inpatient had recently suffered focal pontine stroke, rendering him bedridden and requiring increased nursing care, including assistance with drinking. The patient had received empagliflozin 10 mg once daily for glycaemic control. Investigations revealed hypernatraemia (164 mmol/l), a urine glucose level of 3935 mg/dl, and a creatinine level of 2...

This work makes proposals on the relationship between intracranial pressure (ICP) and hydrocephalus that changes over time with the evolution of the disease. This includes the cerebrospinal fluid (CSF) filling mechanism that leads to an increase in mode pressure if excess fluid volume exacerbates the obstructive process. Elevation in mode occurs because pressure in the central nervous system (CNS) represents a state of reduced flow, rather than an abnormality of volume. Diseases that cause elevated mode pressure by means of a primary edema can lead to hydrocephalus if there is sufficient time and obstruction to flow for the filling mechanism to act...

OBJECTIVE What determines the extent of tissue destruction during brain abscess formation is not known. Pyogenic brain infections cause destruction of brain tissue that greatly exceeds the area occupied by microbes, as seen in experimental studies, pointing to cytotoxic factors other than microbes in pus. This study examined whether brain abscess pus contains cytotoxic proteins that might explain the extent of tissue destruction. METHODS Pus proteins from 20 human brain abscesses and, for comparison, 7 subdural empyemas were analyzed by proteomics mass spectrometry...

The effect of a sodium glucose cotransporter 2 inhibitor (SGLT2i) in reducing heart failure hospitalization in the EMPA-REG OUTCOMES trial has raised the possibility of using these agents to treat established heart failure. We hypothesize that osmotic diuresis induced by SGLT2 inhibition, a distinctly different diuretic mechanism than that of other diuretic classes, results in greater electrolyte-free water clearance and, ultimately, in greater fluid clearance from the interstitial fluid (IF) space than from the circulation, potentially resulting in congestion relief with minimal impact on blood volume, arterial filling and organ perfusion...

BACKGROUND AND OBJECTIVES: Whether transfusion-associated circulatory overload arises as a simple result of over-transfusion or requires another trigger remains unclear. Here, we examined whether respiratory distress could be reproduced by massive transfusion alone in an animal model. MATERIALS AND METHODS: A total of 20 anaesthetized swine were equipped with monitors. Allogeneic blood was obtained from 10 donor swine. A 4-stage loading protocol with each stage equivalent to 25% of the blood volume (BV) in the recipient swine was then used to infuse crystalloid (CR), hydroxyethyl starch (HES) or allogeneic blood (TR) (n = 5 each)...

PURPOSE OF REVIEW: We reviewed the recent advances in the initial approach to resuscitation of sepsis and septic shock patients. RECENT FINDINGS: Sepsis and septic shock are life-threatening emergencies. Two key interventions in the first hour include timely antibiotic therapy and resuscitation. Before any laboratory results, the need for resuscitation is considered if a patient with suspected infection has low blood pressure (BP) or impaired peripheral circulation found at clinical examination...

Bicontinuous microemulsions (BμEs), consisting of water and oil nanodomains separated by surfactant monolayers of near-zero curvature, are potentially valuable systems for purification and delivery of biomolecules, for hosting multiphasic biochemical reactions, and as templating media for preparing nanomaterials. We formed Winsor-III systems by mixing aqueous protein and sodium dodecyl sulfate (SDS) solutions with dodecane and 1-pentanol (cosurfactant) to efficiently extract proteins into the middle (BμE) phase...

BACKGROUND: Breast milk alone, given at standard recommended volumes (150 to 180 mL/kg/d), is not adequate to meet the protein, energy, and other nutrient requirements of growing preterm or low birth weight infants. One strategy that may be used to address these potential nutrient deficits is to give infants enteral feeds in excess of 200 mL/kg/d ('high-volume' feeds). This approach may increase nutrient uptake and growth rates, but concerns include that high-volume enteral feeds may cause feed intolerance, gastro-oesophageal reflux, aspiration pneumonia, necrotising enterocolitis, or complications related to fluid overload, including patent ductus arteriosus and bronchopulmonary dysplasia...

Circulating cell-free DNA (ccfDNA) can be found in various body fluids, i.e., blood (serum and plasma), urine, pleural effusions, and ascites. While ccfDNA predominantly originates from physiological processes, a fraction might be related to pathological events, e.g., cancer. Aberrant DNA methylation, which is considered a hallmark of cancer, can be assessed accurately in ccfDNA. Consequently, DNA methylation testing in body fluids represents a powerful diagnostic tool in the clinical management of malignant diseases...
