Data collection was consistent, where possible, with the previous years’ landline RDD phone surveys and between frames. Survey operational data for the frames were compared and combined. Demographic information from the interview data for mobile-only phone users, both, and total were compared to the landline frame using.2 tests. Demographic information for each frame, landline and the mobile-only (equivalent to a screening dual frame design), and the frames combined (with appropriate overlap adjustment) were compared to the NSW demographic profile from this website the 2011 census using X-2 tests.
Results: In the first quarter of 2012, 3395 interviews were completed with 2171 respondents (63.9%)
from the landline frame (17.6% landline only) and 1224 (36.1%) from the mobile frame (25.8%
mobile only). Overall combined response, contact and cooperation rates were 33.1%, 65.1% and 72.2% respectively. As expected from previous research, the demographic profile of the mobile-only phone respondents differed most (more that were young, males, Aboriginal and Torres Strait Islanders, overseas born and single) compared to the landline frame responders. The profile of respondents from the two frames combined, with overlap adjustment, was most ACY-738 supplier similar to the latest New South Wales (NSW) population profile.
Conclusions: The inclusion of the mobile phone numbers, through an overlapping dual-frame design, did not impact negatively on response rates or data collection, and although costing more the design was still cost-effective because of the additional interviews that were conducted with young people, Aboriginal and Torres Strait Islanders and people who were born overseas resulting in a more representative overall sample.”
“SETTING: Several matrix metalloproteinase (MMP) polymorphisms P005091 favouring the development of lung fibrosis after pulmonary tuberculosis (TB) have been described.
OBJECTIVE: To
investigate the association of MMP-1, MMP-9 and MMP-1 2 polymorphisms with the development of fibrosis in pulmonary TB.
DESIGN: We studied 49 normal subjects and 98 TB patients. We analysed the association between MMP polymorphisms and clinical indices of lung fibrosis by serial chest radiography for 1 year after completion of treatment.
RESULTS: The frequency of the MMP-1(-1607G) polymorphism was significantly higher in TB patients with moderate to advanced pulmonary fibrosis than in those with minimal to mild fibrosis. Having at least one -1607G MMP-1 polymorphism increased the risk of moderate and advanced fibrosis respectively by 5.04 (95%CI 1.25-20.30) and 9.87 (95%CI 2.39-40.88) fold. There was no association of MMP-9(-1562T) and MMP-12(Asn357Ser) polymorphisms with lung fibrosis. The production of MMP-1 from monocytes stimulated by interleukin-1 beta was increased in subjects with the 1G allele genotype compared to the 2G/2G genotype.
