An Online Cost Calculator for Estimating the Economic Cost of Illness Due to Shiga Toxin-Producing E. coli (STEC) 0157 Infections
Provedor de dados: 31
Autores: Frenzen,   Paul D.
Shiga toxin-producing E. coli (STEC) O157 is a significant cause of foodborne illness in the United States. ERS estimated the economic cost of illness due to this pathogen— $405.2 million (in 2003 dollars)—using the most recent estimate (1997) of the annual number of STEC O157 cases by the Centers for Disease Control and Prevention (CDC) and medical and cost data from the Foodborne Diseases Active Surveillance Network. CDC is currently updating its estimate of annual cases. As new information becomes available, the ERS online Foodborne Illness Cost Calculator enables users to review and modify the assumptions underlying the STEC O157 cost estimate, such as the number of cases, and then recalculate the cost, adjusted for inflation for any year from 1997 to...

A Comparison of Methodologies for Valuing Decreased Health Effects from Wildfire Smoke
Provedor de dados: 31
Autores: Richardson,   Leslie; Loomis,   John B.; Champ,   Patricia A.
Wildfire seasons are becoming longer and more intense throughout the world, making it increasingly important to monetize the full damages caused by wildfires when analyzing various fire management policies. We estimate the economic costs of the health effects associated with exposure to wildfire smoke using a simple cost of illness approach and for the first time to our knowledge we estimate willingness-to-pay (WTP) for a decrease in symptom days from wildfire smoke using the contingent valuation method and the averting behavior method. Comparing estimates across all three common approaches for estimating the economic cost of exposure to an air pollutant is an important contribution to the literature. This study uses data from the largest wildfire in Los...

OBJECTIVE: To evaluate the effect of Chlamydia trachomatis infection during pregnancy on perinatal morbidity and mortality. METHODS: Systematic review and meta-analysis in an electronic database and manual, combining high sensitivity specific descriptors seeking to answer the research objective. The articles considered to be of high methodological quality (score above 6 on the Newcastle-Ottawa Scale) were assessed by meta-analysis. RESULTS: Summary estimates of 12 studies were calculated by means of Mantel-Haenszel test with 95% confidence interval. It was observed that Chlamydia infection during pregnancy increased risk of preterm labor (relative risk (RR) = 1.35 [1.11, 1.63]), low birth weight (RR = 1.52 [1.24, 1.87]) and perinatal mortality (RR = 1.84...

Relationship between passive immunity and morbidity and weight gain in dairy cattle
Provedor de dados: 65
Autores: Moraes,Mauro Pires; Weiblen,Rudi; Rebelatto,Marlon Cesar; Silva,Adriana Moraes da.
Serum samples from 87 calves from a dairy herd in Southern Brazil were collected to determine the levels of passive transfer and its relationship to morbidity and mean daily weight gain (MDG). Serum immunoglobulin (Ig) levels were measured by the zinc sulfate turbidity test at 24 hours of age in the calves. The average serum Ig level was 11.40g/l. Fourteen out of 87 calves (16.1%) showed serum Ig levels one standard deviation below the mean (4.59g/l) and were considered as having failure of passive immunity transfer (FPT). The occurrence of diarrhea from birth to weaning was higher in the FPT group (100%) than the normal group (90.7%) but the difference was not significant. The occurrence of signs of respiratory disease was similar in both groups (35.7%...
