ON TRANSIENT RENAL CONGESTION.

Focus on renal congestion in heart failure

Hospitalizations due to heart failure are increasing steadily despite advances in medicine. Patients hospitalized for worsening heart failure have high mortality in hospital and within the months following discharge. Kidney dysfunction is associated with adverse outcomes in heart failure patients. Recent evidence suggests that both deterioration in kidney function and renal congestion are impor...

Transient Behaviors of TCP-friendly Congestion Control Protocols

We investigate the fairness, smoothness, responsiveness, and aggressiveness of TCP and three representative TCP-friendly congestion control protocols: GAIMD, TFRC, and TEAR. The properties are evaluated both analytically and via simulation by studying protocol responses to three network environment changes. The first environment change is the inherent fluctuations in a stationary network enviro...

Models and Algorithms for Transient Queueing Congestion at Airports

W e develop a new model for studying the phenomenon of congestion in a transient environment, focusing on the problem of aircraft landings at a busy "hub" airport. Our model is based on a Markov / semi-Markov treatment of changes in the weather, the principal source of uncertainty governing service times, together with a treatment of the arrival stream as time-varying but deterministic. The mod...

Marfan syndrome presenting with transient renal insufficiency.

Transient hypercalcaemia following acute renal failure.

Two patients with transient hypercalcaemia during recovery from acute renal failure are described. The literature is reviewed and possible pathophysiological mechanisms discussed. Patients with renal failure following muscle damage should have regular measurement of plasma calcium.
