Background and purpose: Using practical and non-invasive methods to improve the adequacy of dialysis (i.e. Kt/V) can increase the quality of life and decrease the mortality and morbidity rate in patients under hemodialysis. This study was conducted to investigate the effect of intermittent normal saline bolus on adequacy of dialysis. Materials and methods: In this randomized controlled...
Introduction: The objective of this study was to describe the modalities responses observed following realization a bolus methylprednisolone in children treated for nephrotic syndrome pediatric nephrology unit Abidjan order assess need its our practice. Methods: we carried out descriptive and analytical cross-sectional patients followed up having benefited from administration 3 boluses at dosag...
Introduction: The present study aimed to generate intensity-modulated beams with Aluminium compensating filters for a conventional telecobalt machine based on the outputs of a treatment planning system (TPS) performing forward planning and cannot simulate directly the compensating filter. Materials and Methods: In order to achieve the beam intensity modulation during treatment planning with th...
This study aimed to assess pharyngeal function between no bolus and bolus propofol induced sedation during gastric endoscopic submucosal dissection. A retrospective study was conducted involving consecutive gastric cancer patients. Patients in the no bolus group received a 3 mg/kg/h maintenance dose of propofol after the initiation of sedation without bolus injection. All patients in the bolus ...
BACKGROUND A detailed contrast bolus propagation model is essential for optimizing bolus-chasing Computed Tomography Angiography (CTA). Bolus characteristics were studied using bolus-timing datasets from Magnetic Resonance Angiography (MRA) for adaptive controller design and validation. METHODS MRA bolus-timing datasets of the aorta in thirty patients were analyzed by a program developed with...
BACKGROUND The utility of combined oesophageal pressure-impedance recording has been enhanced by automation of data analysis. OBJECTIVE To understand how oesophageal function as measured by automated impedance manometry (AIM) pressure-flow analysis varies with bolus characteristics and subjective perception of bolus passage. METHODS Oesophageal pressure-impedance recordings of 5 and 10 ml l...
