Quantifying fluid overload with portable magnetic resonance sensors
… specifically for the purpose of quantifying fluid overload. MRI is used extensively in clinical medicine, but it is still not used for routine diagnostics due to high cost, limited availability, and long scan times. Many of these impracticalities come from the hardware requirements associated …

Increasing Self Care Compliance with Follow-up Appointments
… and their families on reducing incidents of fluid overload with lifestyle changes such as, following a low sodium diet, watching for early signs and symptoms of fluid overload, taking medications regularly and getting daily activity. The Congestive Heart Failure team wants to ensure that …

Patient outcomes in a PD First Program in Cape Town, South Africa
… included demographics, adequacy, modality, fluid, cardiovascular risk and diabetes. The influences of these variables on peritonitis rate, technique and patient survival were assessed. Results: 230 patients were initiated on PD, 31 were excluded as they were on PD for < 90 days. The mean age …

Portable magnetic resonance sensors and methods for noninvasive disease diagnostics
Many diseases manifest as a shift in fluids between distinct tissue fluid compartments. For example, fluid depletion and fluid overload lead to a deficit or accumulation of fluids within the intramuscular interstitial space. A direct measurement of these fluid shifts could serve as a highly …

Clinical characteristics of end stage renal disease patients at hemodialysis initiation
… The main reasons to start hemodialysis were fluid overload (38.4%) and uremic symptoms (35.0%). DM patents were older and started dialysis at higher eGFR levels than non-DM patients (mean eGFR by the MDRD equation, 6.92 ± 3.63 vs 5.41 ± 2.91, p < 0.001). Hemodialysis was started in 59.2% …

The 5 year outcomes of patients receiving haemodialysis versus peritoneal dialysis at Groote Schuur Hospital, Cape Town, South Africa
… common causes of death were infection (26%) and fluid overload (19%). Having removed those PD patients for whom modality switch was denied due to contraindications to transplantation, survival probability at 1-, 2- and 5- years for HD versus PD was 98.68% (CI: 94.84-99.67), 96.95 (CI: …

A Recurrent Network Approach to G-Computation for Sepsis Outcome Prediction Under Dynamic Treatment Regimes
… involves the administration of intravenous fluids and vasopressors, but prescribing the correct balance of interventions is challenging since both under- and over-resuscitation can lead to adverse outcomes. While many retrospective studies have attempted to understand the relationship …

Dynamic treatment regimens for congestive heart failure
… adverse events. A primary symptom of CHF is fluid overload ("congestion"), which is routinely treated with diuretic therapy. However, choosing a diuretic therapy that maximizes the therapeutic effects while minimizing harmful side effects remains a challenge. In order to assess a patient's …

A portable bioimpedance spectroscopy system for congestive heart failure management
… exercise tolerance, shortness of breath, and fluid buildup in the lungs, legs, and abdomen. While CHF-related mortality has reduced in recent years, this reduction has been accompanied by an increase in hospitalizations and readmissions. This thesis takes the first steps toward developing a …

Lymph Flow in Newborn Lambs : Effects of Change in Osmolality
… that volume loading and alterations in body fluid osmolality cause rapid shifts throughout the body's fluid compartments in the adult dog. The lymph system has been found to be a vital link in the body's ability to compensate for excess fluid, and thus provides a strong defense against edema …

Characteristics and allocation outcomes of patients assessed for the renal replacement therapy at Groote Schuur Hospital (2008-2012)
… disease with either uremic (n=181, 44.4%) or fluid overload (n=179, 43.9%) symptoms as their major presentation. The underlying causes were Hypertension (40.6%), Diabetes (14.4%) and chronic Glomerulonephritis (15.8%). Predictors of rejection from the program included age above 50 years, …

Effects of aminophylline therapy on urine output and renal function in children with acute kidney injury in an African setting
… of AKI is the use of diuretics to reduce fluid overload which is an important indication for initiation of renal replacement therapy (RRT) - dialysis and also an important indicator of morbidity and mortality. Aminophylline, a drug that is well known for its use in the treatment of …

Elucidating the role of LARP6 in cardiovascular remodeling
… angiotensin II and aldosterone signaling, and fluid overload create a distinct milieu of cardiac stressors. To compensate, the heart undergoes a period of necessary structural remodeling. However, chronic/excess remodeling disrupts tissue homeostasis and creates an environment that can …

Fluid and blood pressure management in maintenance hemodialysis patients
… may change due to the removal of extracellular fluid by ultrafiltration and other factors. Because most blood pressure medications are vasodilators or impact other components of cardiovascular function, they may prevent the normal physiological response to changes in volume during dialysis, …

Ultrasound measurements on the inferior vena cava by renal nursing staff for assessment and management of intravascular volume status in haemodialysis patients
… where the prevalence rate of nurse-documented fluid related intradialytic hypotensive events was measured and a Generalised Estimating Equation (GEE) model was used to predict the likelihood of any form of intradialytic hypotension or postdialytic overhydration. In the next phase a four-step …
