Abstract
The ß(2)-adrenergic receptor (ADRB2) is an important regulator of airway smooth muscle tone. We tested the hypothesis that three functional polymorphisms in the ADRB2 gene (Thr164Ile, Gly16Arg and Gln27Glu) are associated with reduced lung function, asthma or chronic obstructive pulmonary disease (COPD). We first genotyped 8,971 individuals from the Copenhagen City Heart Study for all three polymorphisms. To validate our findings, we genotyped an additional 53,777 individuals from the Copenhagen General Population Study for the Thr164Ile polymorphism. We identified 60,910 Thr164Ile noncarriers, 1,822 heterozygotes and 16 homozygotes. In the Copenhagen City Heart Study, the Thr164Ile genotype was associated with reduced forced expiratory volume in 1 s (FEV(1)) % predicted (trend p = 0.01) and FEV(1)/forced vital capacity (FVC) (p = 0.001): Thr164Ile heterozygotes had 3% and 2% reduced FEV(1) % pred and FEV(1)/FVC, respectively, compared with noncarriers. The odds ratio for COPD in Thr164Ile heterozygotes was 1.46 (95% CI 1.05-2.02). In the Copenhagen General Population Study, the Thr164 genotype associated with reduced FEV(1) % pred (p = 0.04) and FEV(1)/FVC (p

Abstract
The incidence of cardiovascular events remains high in patients with myocardial infarction (MI) despite advances in current therapies. New and better methods for identifying patients at high risk of recurrent cardiovascular (CV) events are needed. This study aimed to analyze the predictive value of an oral glucose tolerance test (OGTT) in patients with acute myocardial infarction without known diabetes mellitus (DM).
The prospective cohort study consisted of 123 men and women aged between 31-80 years who had suffered a previous MI 3-12 months before the examinations. The exclusion criteria were known diabetes mellitus. Patients were followed up over 6.03???1.36 years for CV death, recurrent MI, stroke and unstable angina pectoris. A standard OGTT was performed at baseline.

Abstract
To measure the effectiveness of fluoride varnish (FV) (Duraflor), 5% sodium fluoride, Pharmascience Inc., Montréal, QC, Canada) and caregiver counseling in preventing early childhood caries (ECC) in Aboriginal children in a 2-year community-randomized controlled trial.
Twenty First Nations communities in the Sioux Lookout Zone (SLZ), Northwest Ontario, Canada were randomized to two study groups. All caregivers received oral health counseling, while children in one group received FV twice per year and the controls received no varnish. A total of 1275, 6 months to 5-year-old children from the SLZ communities were enrolled. In addition, a convenience sample of 150 primarily non-Aboriginal children of the same age were recruited from the neighboring community of Thunder Bay and used as comparisons. Longitudinal examinations for the dmft/s indices were conducted by calibrated hygienists in 2003, 2004 and 2005.
Aboriginal children living in the SLZ or in Thunder Bay had significantly higher caries prevalence and severity than non-Aboriginal children in Thunder Bay. FV treatment conferred an 18% reduction in the 2-year mean 'net' dmfs increment for Aboriginal children and a 25% reduction for all children, using cluster analysis to adjust for the intra-cluster correlation among children in the same community. Adjusted odds ratio for caries incidence was 1.96 times higher in the controls than in the FV group (95% CI = 1.08-3.56; P = 0.027). For those caries-free at baseline, the number (of children) needed to treat (NNT) equaled 7.4.
Findings support the use of FV at least twice per year, in conjunction with caregiver counseling, to prevent ECC, reduce caries increment and oral health inequalities between young Aboriginal and non-Aboriginal children.

Abstract
Information is sparse concerning the incidence and prognosis of headache in children from the general population, especially of tension-type headache. In this study, headache diagnoses and symptoms were reassessed in 122 out of 130 schoolchildren after 3 years. Nearly 80% of those with headache at first evaluation still reported headache at follow-up. Although the likelihood of experiencing the same headache diagnosis and symptoms was high, about one-fifth of children with tension-type headache developed migraine and vice versa. Female gender predicted migraine and frequent headache episodes predicted overall headache at follow-up. The estimated average annual incidence was 81 and 65 per 1000 children, for tension-type headache and migraine, respectively. We conclude that there is a considerable risk of developing and maintaining headache during childhood. Headache diagnoses should be reassessed regularly and treatment adjusted. Girls and children with frequent headache have a poorer prognosis and therefore intervention is particularly important in these groups.

Abstract
To determine the impact of a provincial choking prevention program (CPP) on the incidence of aerodigestive foreign body cases among children.
The CPP, including posters, pamphlets, an informative video, and annual participation in the Parents & Kids Fair, was launched throughout Quebec in October 1999. The incidence rates of aerodigestive foreign body cases prior to implementation (during 1997-1998) and subsequently (2000-2002) within the province and our tertiary care centre (Sainte-Justine Hospital) were compared by estimating incidence rate ratios (IRRs) and associated 95% confidence intervals (95% CIs).
No significant changes in the incidence of aerodigestive foreign body cases after program implementation were observed in our hospital (age-adjusted IRR 0.92, 95% CI 0.79-1.07). The provincial rates were higher after program implementation (age-adjusted IRR 1.15, 95% CI 1.05-1.25).
To influence choking prevention habits, modifications to the campaign are required. Strategies are discussed.

Abstract
OBJECTIVES: Previous studies have suggested that abnormal levels of cortisol and testosterone might increase the risk of serious somatic diseases. To test this hypothesis, we conducted a 5-year follow-up study in middle-aged men. METHODS: A population-based cohort study conducted in 1995 amongst 141 Swedish men born in 1944, in whom a clinical examination supplemented by medical history aimed to disclose the presence of cardiovascular disease (CVD) (myocardial infarction, angina pectoris, stroke), type 2 diabetes and hypertension were performed at baseline and at follow-up in the year 2000. In addition, salivary cortisol levels were measured repeatedly over the day. Serum testosterone concentrations were also determined. Using the baseline data, an algorithm was constructed, which classified the secretion pattern of cortisol and testosterone from each individual as being normal or abnormal. RESULTS: By the end of follow-up, men with an abnormal hormone secretion pattern (n = 73) had elevated mean arterial pressure (P = 0.003), fasting insulin (P = 0.009) and insulin : glucose ratio (P = 0.005) compared with men with a normal secretion pattern (n = 68). Body mass index, waist circumference, and waist : hip ratio were significantly elevated in both groups. However, the 5-year incidence of CVD, type 2 diabetes, and hypertension were significantly higher (P

Abstract
PURPOSE: To examine the age- and gender-specific 5-year incidence of age-related maculopathy (ARM) and age-related macular degeneration (AMD) in citizens of Reykjavik. DESIGN: Population-based, prospective cohort study. PARTICIPANTS: The cohort was a population-based random sample of citizens 50 years and older. Of 1379 eligible subjects, 1045 had a baseline examination in 1996; 846 of the 958 survivors (88.2%) had a 5-year follow-up examination in 2001. METHODS: The incidence of various characteristics of drusen and pigmentary changes that are typical of ARM were determined using the international classification and grading system for ARM and AMD. MAIN OUTCOME MEASURES: Early ARM and AMD were assessed by masked grading of stereo fundus photographs. RESULTS: Hypopigmentation developed at 5 years in 10.7% of people 50 to 59 years of age (95% confidence interval [CI], 6.9-14.4) and in 25.7% those 70 to 79 years of age (95% CI, 18.4-33.0) at baseline. Age-related macular degeneration developed in no one who was 50 to 59 years of age at baseline. Geographic atrophy (GA) developed in 4.6% (95% CI, 1.2-7.9) and exudative AMD in none of those who were 70 years and older at baseline. CONCLUSIONS: Geographic atrophy is the predominant type of AMD in Iceland, and the ratio of GA to neovascular AMD is higher than in racially similar populations.

Abstract
To investigate, in a population-based cohort of patients with juvenile chronic arthritis (JCA), onset characteristics, progression, outcome, and prognostic factors longitudinally for 5 years.
This cohort consisted of 132 incidence cases identified between 1984 and 1986 in southwestern Sweden followed for 5 years with annual reports of subgroup, joint assessment, disease activity, eye examinations, laboratory measurements, and medication. At the 5-year follow-up, the Childhood Health Assessment Questionnaire (Child-HAQ) was evaluated. European League Against Rheumatism (EULAR) criteria for diagnosis and disease activity were used.
During the 5 years only four patients were lost to follow-up, 34% changed subgroup and 8% developed uveitis. At the 5-year follow-up the disease was active in 12% of the patients, stable in 28%, inactive in 25%, and in remission in 34%. Among those examined, 24% had radiological changes, of whom half had advanced changes. The Child-HAQ median score at the 5-year follow-up was 0.13 (range 0.0-1.9). The number of involved joints at inclusion correlated positively with active disease at the 5-year follow-up. Age at disease onset, the number of involved joints, and the number of joints with arthritis correlated positively with continuous disease and Child-HAQ score. CONCLUSION. Our study shows a diverse disease course during the first 5 years of JCA where one-third changed subgroup and two-thirds did not reach remission. Age of disease onset, the number of involved joints, and the number of joints with arthritis at inclusion were associated with poor outcome at the 5-year follow-up.

Abstract
During a 6-month period, 892 positive blood cultures were detected in the Copenhagen County hospitals. 302 (34%) were regarded as contaminations, and of the remaining cases 419 (71%) were community-acquired and 171 (29%) hospital-acquired, giving incidence rates of 6.8/1,000 admissions and 2.8/1,000 admissions, respectively. Both frequency and rate of hospital-acquired bacteremia were lower compared to most other studies. E. coli was more commonly found in community-acquired infections, while coagulase-negative staphylococci were the organisms most often considered as a contaminant. The main causative organisms in hospital-acquired infections were S. aureus (n = 37) and E. coli (n = 34). The proportion of polymicrobial bacteremias in this study was lower compared to most other studies (8%). E. coli from hospital-acquired infections were resistant to ampicillin in 42% of cases, but other Enterobacteriaceae showed higher percentage of resistance to beta-lactam antibiotics. S. aureus was penicillin-resistant in 92% of cases, but no methicillin-resistant strains were isolated. The frequency of antibiotic resistance was low compared to reports from other countries. A total of 136 hospital-acquired cases were followed prospectively. 61% of the patients were male and 46% were > or = 60 years of age. Most patients had predisposing diseases, 90% had foreign body and/or recent surgery performed, and 74 (54%) had an intraveneous catheter. The portal of entry was known in 132 (97%) of the cases, the most common being the urinary tract (42%), followed by an intravenous catheter (30%). The prevalence of urinary tract catheters gave an increased number of cases with E. coli bacteremia. The mortality was 16%.
