Causal conclusions cannot be made from our data. A beneficial effect of sun exposure per se needs to be examined in other studies.”
“OBJECTIVES: Childhood cancer mortality has substantially declined worldwide as a result of significant advances in global cancer care. Because limited information is available in Brazil, we analyzed trends in childhood cancer mortality in five Brazilian regions over 29 years.
METHODS: Data from children 0-14 years old were extracted from the Health Mortality Information System for 1979 through 2008. Age-adjusted
mortality rates, crude mortality rates, and age-specific mortality rates by geographic region of Brazil and for the entire country find more were analyzed for all cancers and leukemia. Mortality trends were evaluated for all childhood cancers and leukemia using joinpoint regression.
RESULTS: Mortality declined significantly for the entire period (1979-2008) for children with leukemia. Childhood cancer mortality rates declined in the South and Southeast, remained stable in the Middle West, and increased in the North and Northeast. Although the mortality rates did not unilaterally decrease in all regions, the age-adjusted mortality rates were relatively similar among the five Brazilian regions from 2006-2008.
CONCLUSIONS:
Childhood cancer mortality Epigenetic inhibitor declined 1.2 to 1.6% per year in the South and Southeast regions.”
“Objective: To examine the safety and effectiveness of fully implantable middle ear devices in the treatment of hearing loss.
Data Sources: MEDLINE, EMBASE, The Cochrane Library, Web of Science, CINAHL, PsycINFO, and the Centre for Reviews and Dissemination were MS-275 mouse searched without date or language limits.
Study Selection: Titles and abstracts of 7,700 citations were screened, and 30 articles were selected for full review, of which, 7 articles on the Esteem and 13 on the Carina met the study’s eligibility criteria.
Data Extraction: Information was
extracted using a pretested data abstraction form, and study quality was assessed using the Oxford Centre for Evidence-Based Medicine Levels of Evidence.
Data Synthesis: Because of heterogeneity across studies, meta-analysis was not performed, and comparisons were made by structured review.
Conclusion: The majority of studies were quasi-experimental, prepost comparisons of aided and unaided conditions. Complication rates with the Esteem were higher than with the Carina, and most commonly included taste disturbance. However, device failure was common with the Carina, predominately related to charging difficulties. For both devices, clinically significant improvements in functional gain, speech reception, and speech recognition over the unaided condition were found. In studies comparing the Esteem or Carina to hearing aids, findings were mixed. Although improvements in functional gain were similar to those for hearing aids, speech recognition and quality of life were greater with the implants.
