Fluid and electrolyte pathophysiology in common febrile illness in children and the implications for clinical management.

Achieving fluid homeostasis and the management of fluid and electrolyte complications are constants in the treatment of seriously ill children worldwide. Consensus on the most appropriate fluid strategy for unwell children has been difficult to achieve and has evolved over the last two decades, most notably in high-income countries where adverse events relating to poor fluid management were identified more readily, and official robust inquiries were possible. However, this has not been the situation in many low-income settings where fluids that are prohibited from use in high-income countries may be all that are available, local guidelines and processes to recognise adverse events are not developed, and there has been limited training on safe fluid management for front-line healthcare workers.

Indoor Air Quality and Respiratory Health among Malay Preschool Children in Selangor.

Indoor air quality (IAQ) has been the object of several studies due to its adverse health effects on children. Methods. A cross-sectional comparative study was carried out among Malay children in Balakong (2 studied preschools) and Bangi (2 comparative preschools), Selangor, with the aims of determining IAQ and its association with respiratory health.

Experimental study of a complete anastomosis model for the coronary artery bypass.

Local hemodynamics of complete bypass model under steady flow condition was investigated using the instantaneous velocity fields acquired by Particle Image Velocimetry (PIV). At proximal anastomosis a low velocity region was found near the heel along the graft inner wall and a stagnation point was found near the toe. The velocity profile was relatively smooth except slightly skew toward the graft outer wall.

In-vitro Experimental Validation Of Hemodynamics Study For Proximal Anastomosis Models.

Hemodynamics is widely believed to correlate with the stenosis of coronary artery bypass graft (CABG). Although some researchers had investigated distal anastomosis, further studies upon the proximal anastomosis are still necessary as the initiation and growth of the stenosis process may be influenced by the nature of the flow at the proximal anastomosis. Therefore in this project, flow characteristics of proximal anastomosis models were studied numerically in order to enhance the understanding of the stenosis pathophysiological process and particle image velocimetry (PIV) measurements were also carried out to validate the numerical simulation results.

Analysis of blood flow in an out-of-plane CABG model.

Coronary artery bypass graft (CABG) is a routine surgical treatment for ischemic and infarcted myocardium. A large number of CABG fail postoperatively because of intimal hyperplasia within months or years. The cause of this failure is thought to be partly related to the flow patterns and shear stresses acting on the endothelial cells.
