BACKGROUND There is a high and rising rate of immune-mediated diseases in the Western world. Immigrants from South Asia have been reported to be at higher risk upon arrival to the West. We determined the risk of immune-mediated diseases in South Asian and other immigrants to Ontario, Canada, and their Ontario-born children. METHODS Population-based cohorts of patients with asthma, type 1 diab...

Background There are limited data available on factors associated with length of stay (LOS) in cases of acute ischemic stroke according to Poisson analysis, which is more appropriate than other methods. Materials and methods We retrospectively reviewed medical summary charts of patients with acute ischemic stroke in 30 hospitals across northeast Thailand, with the main outcome as LOS. Poisson...

AIM To examine the influence of the field of view (FOV) and voxel size on the measurement of the volume of simulated internal root resorption (IRR) lesions through cone-beam computed tomography (CBCT). METHODOLOGY Eleven single-rooted teeth with IRR simulated by acid demineralization were studied. CBCT images were acquired using large FOV (voxel sizes of 0.200, 0.250 and 0.300 mm) and limited...

Objectives To examine the effect of opioid maintenance treatment (OMT) on somatic morbidity in a cohort of OMT patients. Design Retrospective cohort study. Setting OMT programme in two Norwegian counties. Participants 200 OMT patients, participation rate 71.2%. Main outcome measures Incidence rates (IR) before, during and after OMT for acute/subacute hospital-treated somatic disease inciden...

BACKGROUND The prevalence of obesity is on the increase in Ghana, and the intake of sugar-sweetened beverages may be a determinant. The aim of this study is to use quantitative and qualitative data to investigate water intake among Ghanaian youth 15-34 years old. METHODS The 2008 Ghana Demographic and Health Survey data is used to investigate the effects of socio-demographic factors on water ...

BACKGROUND Area-based measures of economic deprivation are seldom applied to large medical records databases to establish population-scale associations between deprivation and disease. OBJECTIVE To study the association between deprivation and incidence of common cancer types in a Southern European region. METHODS Retrospective ecological study using the SIDIAP (Information System for the D...

BACKGROUND This study aimed to assess the association between exposure to indoor air pollution in DCCs (Child Day Care Centers) and the respiratory symptoms of children under 6 years old. METHODS Air quality data were collected three times regarding to seasonal variation. Pollutants measured in 11 DCCs included PM₁₀, CO, NO₂, SO₂, O₃, benzene, bacteria, fungi, and dust mite. The frequencyof r...

Infrared-reflective (IRR) treatment of automotive glass has been shown to reduce air temperature in vehicle cabins, thereby increasing fuel economy and occupant comfort. Its effect on radiant heat, however, may augment these benefits. In this study, the hypothesis that radiant heat affects subjective comfort ratings in a vehicle was tested. IRR films were systematically applied to the driver-si...

Irr and RirA, rather than Fur, serve as the major iron-responsive regulators in the alphaproteobacteria. With only a few exceptions, however, the relative contributions of these transcriptional regulators to the differential expression of specific iron metabolism genes in Brucella strains are unclear. The gene encoding the outer membrane heme transporter BhuA exhibits maximum expression in Bruc...

In this paper we consider the theta correspondence between the sets Irr(GSp(2, k)) and Irr(GO(X)) when k is a nonarchimedean local field and dimk X = 4. Our main theorem determines all the elements of Irr(GO(X)) that occur in the correspondence. The answer involves distinguished representations. As a corollary, we characterize all the elements of Irr(O(X)) that occur in the theta correspondence...
