Occupational burns treated in emergency departments.

Background: Despite reported declines, occupational burn injuries remain a workplace safety concern. More severe burns may result in costly medical treatment and long-term physical and psychological consequences.

Methods: We used the National Electronic Injury Surveillance System-Occupational Supplement to produce national estimates of burns treated in emergency departments (EDs).

Work-related knee injuries treated in US emergency departments.

Objective: To characterize work-related knee injuries treated in US emergency departments (EDs).

Methods: We characterized work-related knee injuries treated in EDs in 2007 and examined trends from 1998 to 2007 by using the National Electronic Injury Surveillance System-occupational supplement.

Results: In 2007, 184,300 (± 54,000; 95% confidence interval) occupational knee injuries were treated in US EDs, accounting for 5% of the 3.

A comparison of fatal occupational injury event characteristics from the Census of Fatal Occupational Injuries and the Vital Statistics Mortality System.

Objectives: The aim of this study was to examine utility of appending International Classification of Diseases (ICD) codes from Vital Statistics Mortality (VSM) data to Bureau of Labor Statistics (BLS) Census of Fatal Occupational Injuries (CFOI), and compare occupational event characteristics based on ICD external cause and BLS Occupational Injury and Illness Classification System (OIICS) event codes.

Methods: We linked VSM records with CFOI records for 2003 and 2004.

Results: Ninety-five percent of approximately 11,000 CFOI cases were linked to VSM cases.

Variations on a theme: diversification of cuticular hydrocarbons in a clade of cactophilic Drosophila.

Background: We characterized variation and chemical composition of epicuticular hydrocarbons (CHCs) in the seven species of the Drosophila buzzatii cluster with gas chromatography/mass spectrometry. Despite the critical role of CHCs in providing resistance to desiccation and involvement in communication, such as courtship behavior, mating, and aggregation, few studies have investigated how CHC profiles evolve within and between species in a phylogenetic context. We analyzed quantitative differences in CHC profiles in populations of the D.

Preventing heat-related illness among agricultural workers.

Hyperthermia from exertion and environmental conditions during agricultural work manifests itself by various symptoms and may lead to death. From 1992 through 2006, 68 workers employed in crop production and related services died from heat-related illness. The crop worker fatality rate averaged 4 heat-related deaths per one million workers per year-20 times higher than the 0.

Occupational injuries among emergency responders.

Background: Emergency responders frequently incur injuries while providing medical, fire, and law enforcement services. National surveillance systems provide fragmented perspectives on responder injuries because they omit specific classes of workers (e.g.

Premating isolation is determined by larval rearing substrates in cactophilic Drosophila mojavensis. VII. Effects of larval dietary fatty acids on adult epicuticular hydrocarbons.

Low concentrations of dietary triacylglycerols including tristearin, triolein, and tripalmitolein, were assessed to determine their effects during egg to pupal stages on adult epicuticular hydrocarbon (EHC) variation in cactophilic Drosophila mojavensis. Triacylglycerols were added singly and in combination at concentrations of 1%, 3%, and 9% to a lipid-free culture medium. Control diets included Carolina Drosophila and lipid-free media.

Cuticular hydrocarbons of Drosophila birchii and D. serrata: identification and role in mate choice in D. serrata.

The cuticular hydrocarbon compositions of two sympatric species of Australian Drosophila in the montium subgroup of the melanogaster group that use cuticular hydrocarbons in mate recognition have been characterized. Drosophila birchii has 34 components in greater than trace amounts, with a carbon number range of C20 to C33. Drosophila serrata has 21 components above trace level and a carbon number range of C24 to C31.
