Methods: A total of 88 cognitive interviews were conducted with 77 children and adolescents across
two sites on 318 items. From this initial item bank, 25 items were deleted and 35 were revised and underwent a second round of cognitive interviews. A total of 293 items were retained for field testing.
Results: Children as young as 8 years of age were able to comprehend the majority of items, response options, directions, recall period, and identify problems with language that was difficult for them to understand. Cognitive interviews indicated issues with item comprehension on several items which led to alternative wording for these items.
Conclusion: Children ages 8-17 years were able to comprehend most item stems and response options in the present study. Field testing with the resulting INCB018424 manufacturer items and response options is presently being conducted as part of the Screening Library solubility dmso PROMIS Pediatric Item Bank development process.”
“Objectives: Genetic variants in Toll-like receptors (TLRs) are considered a potential indicator for host susceptibility to and outcome of several infectious diseases including
tuberculosis. The aim of this study was to determine whether -129 C/G and Met1Val polymorphisms of TLR8 were associated with pediatric pulmonary tuberculosis in Turkish population.
Methods: The -129 C/G and Met1Val polymorphisms were studied in 124 children with pulmonary tuberculosis compared to 150 age-matched healthy control subjects.
Results: We did not identify any statistically significant differences between the patients with TB and control groups with regard to the frequency of genotypes GG or G/(-), CG, and CC or C/(-); and alleles
G and C at rs3764879 (p > 0.05). We found a strong association with genotype A/(-) at rs3764880 with susceptibility to pulmonary TB in males (OR 2.87, 95% CI 1.38-5.98, p = 0.007).
Conclusions: Our results provide evidence, for the first time, of a role for the TLR8 gene in susceptibility to pulmonary TB in male children. Additional research to verify our results are necessary. Tuberculosis in children presents particularly difficult challenges, but research priorities and advances in pediatric tuberculosis could provide wider insights learn more and opportunities for tuberculosis control.”
“Plasmodium falciparum malaria is a serious tropical disease that causes more than one million deaths each year, most of them in Africa. It is transmitted by a range of Anopheles mosquitoes and the risk of disease varies greatly across the continent. The “”entomological inoculation rate”" is the commonly-used measure of the intensity of malaria transmission, yet the methods used are currently not standardized, nor do they take the ecological, demographic, and socioeconomic differences across populations into account.
