There are two main methods that can be employed to build a system that provides High Application Availability (HAA). The first is to construct components, both hardware and software, that exhibit a very long mean time between failures (MTBF). The longer this time, the better the system is at supporting HAA. Systems that exhibit high MTBF are very expensive to build, so much so, that their cost ...

BACKGROUND Evidence suggests that patients with normal hemoglobin (Hgb) levels on hospital admission who subsequently develop hospital-acquired anemia (HAA) may be at risk for adverse outcomes. Our objectives were to (1) determine the prevalence of HAA and (2) examine whether HAA is associated with increased mortality, length of stay (LOS), and total hospital charges. METHODS The population c...

BACKGROUND Expenses with coronary artery bypass grafting (CABG) surgery and coronary angioplasty (CA) represented a significant cost to SUS. OBJECTIVE To analyze SUS expenses with CABG and CA and their performance in hospitals in the state of Rio de Janeiro (SRJ), from 1999 to 2008. METHODS The information came from paid HAA in hospitals with more than 100 revascularization procedures. Mort...

Inhalation exposure to haloacetic acids (HAAs) and haloketones (HKs) in contaminated drinking water occurs during showering. The size distribution of the aerosols generated by a shower was determined using an eight size-range particle counter, which measured particles from 0.1 to >2 microm. An exponential increase in aerosol numbers was observed while the shower water was on, while the aerosol ...

An attempt was made to identify all patients diagnosed as having deep vein thrombosis (DVT) in a large teaching hospital during one year. A review of the radiology records showed that 124 (81%) of the 154 venograms performed were for suspected DVT, and that the diagnosis was confirmed in 57 (46%). During the same period, the Hospital Activity Analysis (HAA) records revealed 174 episodes classif...

The objective of this investigation was to examine the effectiveness of a magnetic ion exchange resin (MIEX) to enhance the coagulation of disinfection by-product precursors in nine surface waters, each representing a different element of the USEPA's 3 x 3 enhanced coagulation matrix. The effect of MIEX-pretreatment on the requisite alum dose needed for subsequent coagulation of turbidity was a...

Conformation-sensitive gel electrophoresis is a useful method for identifying allele polymorphism; it provides co-dominant molecular markers. Using this method, we identified genetic variability in the third intron of the fibroin light chain gene, fib-L, in six Bombyx mori strains. Only Chinese C21A strain did not demonstrate allelic alterations, showing only homoduplex DNA molecules. We found ...

In this double-blind, randomized clinical trial, 36 healthy male volunteers were randomly distributed into three groups (n = 12) that underwent a three-step treatment. For four consecutive days, we alternately administered a standardized dried extract of Equisetum arvense (EADE, 900 mg/day), placebo (corn starch, 900 mg/day), or hydrochlorothiazide (25 mg/day), separated by a 10-day washout per...
