RESUMO

Paediatric tuberculosis (TB) is a key indicator for recent transmission and presents a reservoir for the disease. We describe trends in epidemiology, microbiological characteristics and treatment outcome in Denmark between 2000 and 2009. Data were retrieved from the national TB surveillance system and the International Reference Laboratory of Mycobacteriology. In total, 323 TB cases were reported in children aged <15 years, accounting for 7.6% of all notified cases in Denmark. The overall incidence rate of childhood TB declined from 4.1 per 100,000 to 1.9 per 100,000 in the study period. Immigrant children comprised 79.6% of all cases, with the highest incidence rate of 94.1 per 100,000 children in 2001. In contrast to immigrant children, the majority of Danish children were aged <5 years and had a known exposure to TB. Pulmonary TB was the commonest presentation. Only half of the cases were culture confirmed. We observed an overall decreasing trend in the child to adult notification ratio, but a slight increase in the ratio when calculated specifically for ethnic Danes. Childhood TB needs continuous attention with a special focus on risk groups. Emphasis on improving early TB case detection, contact tracing and further implementation of preventive treatment is necessary.

RESUMO

AIMS: The impact of insulin secretagogues (ISs) on long-term major clinical outcomes in type 2 diabetes remains unclear. We examined mortality and cardiovascular risk associated with all available ISs compared with metformin in a nationwide study. METHODS AND RESULTS: All Danish residents >20 years, initiating single-agent ISs or metformin between 1997 and 2006 were followed for up to 9 years (median 3.3 years) by individual-level linkage of nationwide registers. All-cause mortality, cardiovascular mortality, and the composite of myocardial infarction (MI), stroke, and cardiovascular mortality associated with individual ISs were investigated in patients with or without previous MI by multivariable Cox proportional-hazard analyses including propensity analyses. A total of 107 806 subjects were included, of whom 9607 had previous MI. Compared with metformin, glimepiride (hazard ratios and 95% confidence intervals): 1.32 (1.24-1.40), glibenclamide: 1.19 (1.11-1.28), glipizide: 1.27 (1.17-1.38), and tolbutamide: 1.28 (1.17-1.39) were associated with increased all-cause mortality in patients without previous MI. The corresponding results for patients with previous MI were as follows: glimepiride: 1.30 (1.11-1.44), glibenclamide: 1.47 (1.22-1.76), glipizide: 1.53 (1.23-1.89), and tolbutamide: 1.47 (1.17-1.84). Results for gliclazide [1.05 (0.94-1.16) and 0.90 (0.68-1.20)] and repaglinide and [0.97 (0.81-1.15) and 1.29 (0.86-1.94)] were not statistically different from metformin in both patients without and with previous MI, respectively. Results were similar for cardiovascular mortality and for the composite endpoint. CONCLUSION: Monotherapy with the most used ISs, including glimepiride, glibenclamide, glipizide, and tolbutamide, seems to be associated with increased mortality and cardiovascular risk compared with metformin. Gliclazide and repaglinide appear to be associated with a lower risk than other ISs.

RESUMO

OBJECTIVES: To explore the relationship between childhood socioeconomic position (SEP) and filling of medicine prescriptions for prevention of cardiovascular diseases (CVDs), with young adult intelligence (IQ) as a potential mediator. DESIGN: Birth cohort study with logistic and Cox-proportional hazard regression analyses of associations between childhood SEP, retrieved from birth certificates, and prevalence, initiation of and refill persistency for CVD preventive medicine. SETTING: Denmark. PARTICIPANTS: 8736 Danish men born in 1953, who had no CVD at the start of follow-up in 1995, were followed in the Danish National Prescription Register for initiation of and refill persistency for antihypertensives and statins, until the end of 2007 (age 54 years). RESULTS: Low childhood SEP at age 18 was not associated with prescription fillings of antihypertensives, but was weakly associated with initiation of statins (HR = 1.19 (95% CI 1.00 to1.42)). This estimate was attenuated when IQ was entered into the model (HR=1.10 (95% CI 0.91 to 1.23)). Low childhood SEP was also associated with decreased refill persistency for statins (HR=2.23 (95% CI 1.13 to 4.40)). Thus, the HR for SEP only changed slightly (HR=2.24 (95% CI 1.11 to 4.52)) when IQ was entered into the model, but entering other covariates (education and body mass index in young adulthood and income in midlife) into the model attenuated the HR to 2.04 (95% CI 1.00 to 4.16). CONCLUSIONS: Low childhood SEP was related to more frequent initiation of and poorer refill persistency for statins. IQ in young adulthood explained most of the association between childhood SEP and initiation of statins, but had no impact on refill persistency.

RESUMO

Objectives. The aim of the study was to investigate whether the use of the antifolate antibiotic trimethoprim during the 12 weeks before conception was associated with congenital malformations. Methods. We conducted a nationwide register-based cohort study including all Danish women giving birth from 1997 to 2004. All women with at least one prescription of trimethoprim dispensed during the 12 weeks before conception were identified. Results. There was a doubling of congenital malformations in offspring to women exposed to trimethoprim in the 12 weeks before conception. The adjusted odds ratio (OR) of major congenital malformation was 1.87, 95% confidence interval (CI) 1.25-2.81. There was a significant increase in major malformations of the heart (OR = 2.49; 1.18-5.26) and limbs (OR = 2.18; 1.13-4.23). Conclusions. In this study, we found an association between exposure to trimethoprim during the 12 weeks before conception and an increased risk of heart and limb defects.

RESUMO

OBJECTIVE: To investigate whether distance from a patient's home to the nearest invasive centre influenced the invasive treatment strategy in acute coronary syndrome (ACS). METHODS: This was an observational cohort study using nationwide registries involving 24,910 patients admitted with ACS (median age 67, range 30-90 years). All persons were grouped in tertiles according to the distance from their residence to the invasive centre. Cox proportional hazard models were applied to estimate the differences in coronary angiography and revascularisation rate within 60 days of admission according to the distance to the centre. The end points were coronary angiography and subsequent revascularisation. RESULTS: Of 24,910 patients with a first ACS, 33% resided <21 km from one of the five invasive centres in Denmark, 33% lived between 21 and 64 km away and 34% lived >64 km away. The incidence of coronary angiography was 68% for long distance versus 77% for short distance (p<0.05), with an HR of 0.78 (95% CI 0.75 to 0.81, p<0.0001). Adjustment for patient characteristics such as age, sex, co-morbidity and socioeconomic status did not attenuate the difference (HR 0.74, 95% CI 0.71 to 0.77, p<0.0001). Furthermore, revascularisation in the subgroup examined with coronary angiography was less likely for those residing a long distance from the invasive centre compared with those living nearer (adjusted HR of 0.82 (95% CI 0.78 to 0.85, p<0.0001). CONCLUSIONS: In patients hospitalised with ACS, invasive examination and treatment were less likely the further away from an invasive centre the patients resided, thus equal and uniform invasive examination and treatment was not found.
