healthcare associated infective endocarditis an Undesirable Effect of healthcare universalization
Clinical Microbiology and Infection, 2010Co-Authors: Jonathan Matthew Lomas, Francisco Javier Martinezmarcos, Antonio Plata, R Ivanova, Juan Galvez, Juan Reguera, Mariam Noureddine, J. Ruiz, J. Torre, A AlarcónAbstract:Invasive medical technology has led to an increase in the incidence of healthcare-associated infective endocarditis (HAIE). A prospective multicentre cohort study was conducted at seven hospitals in Andalusia, Spain, to establish the characteristics of HAIE and to compare them with those of community-acquired infective endocarditis (CAIE). HAIE was defined as either infective endocarditis (IE) manifesting >48 h after admission to hospital, or IE associated with a significant invasive procedure performed in the 6 months before diagnosis. Seven hundred and ninety-three cases of IE were investigated, and HAIE accounted for 127 (16%). As compared with patients with CAIE, patients with HAIE were older (60.1 ± 14.4 years vs. 53.6 ± 17.5 years) and had more comorbidities (Charlson index 3.3 ± 2.3 vs. 1.8 ± 2.3) and staphylococcal infections (58.3% vs. 24.8%). Vascular manipulation was the main cause of bacteraemia responsible for HAIE (63%). Peripheral vein catheter-associated bacteraemia accounted for 32.8% of the catheter-related bacteraemias. In-hospital mortality (44.9% vs. 24.2%) was higher in the HAIE group. Septic shock (OR 2.2, 95% CI 2.9–30.2) and surgery not performed because of high surgical risk (OR 1.6, 95% CI 1.2–20) were independent predictors of mortality in HAIE. The present study demonstrates that HAIE is a growing health problem associated with high mortality. Careful management of vascular devices is essential to minimize the risk of bacteraemias leading to HAIE.

Effect of Pass Number on Collector Efficiency in Downward-Type Multipass Solar Air Heaters
2014Co-Authors: Ho-ming YehAbstract:The Effect of pass number on the collector efficiency in downward-type multi-pass solar air heaters has been investigated theoretically. The application of multi-pass operation to solar air heaters actually has two conflict Effects. One is the desirable Effect of increasing fluid velocity to decrease the heat transfer resistance. The other is the Undesirable Effect of increasing the hydraulic dissipated power. It is found that considerable improvement in collector efficiency is obtainable if the operation is carried out with multi-pass operation, while the Undesirable Effect is still small and may be ignored. The enhancement increases with increasing pass number, especially for operating at lower air flow rate with higher inlet air temperature.

Solar air heaters with external recycle
Applied Thermal Engineering, 2008Co-Authors: Ho-ming YehAbstract:The Effect of external recycle on the collector efficiency in solar air heaters has been investigated theoretically. The application of external-recycle operation to solar air heaters actually has two conflict Effects. One is the desirable Effect of increasing fluid velocity to decrease the heat transfer resistance. The other is the Undesirable Effect of decreasing the driving force (temperature difference) of heat transfer, due to the remixing at the inlet. It is found that considerable improvement in collector efficiency is obtainable if the operation is carried out with an external recycle, where the desirable Effect overcomes the Undesirable Effect. The enhancement increases with increasing reflux ratio, especially for operating at lower air flow rate with higher inlet air temperature.
