Emergency Heart failure Mortality Risk Grade may help to reduce heart failure admissions.

INTRODUCTION: Hospital admissions for heart failure (HF) are frequent and pose a heavy burden on health care resources. Currently, the decision to hospitalise is based on clinical judgement rather than on prognostic risk stratification. The Emergency Heart failure Mortality Risk Grade (EHMRG) was recently developed to identify high-risk HF patients in the emergency department (ED). OBJECTIVE: To assess the ability of the EHMRG to predict 30-day mortality in Dutch HF patients visiting the ED and to evaluate whether the EHMRG could help to reduce the number of hospital admissions for decompensated HF. METHODS: Patients visiting the ED for decompensated HF were included. The decision to hospitalise or discharge was based on clinical judgement. The EHMRG was calculated retrospectively. Based on their EHMRG, patients were stratified as very low risk, low risk, intermediate risk, high risk and very high risk. RESULTS: In 227 patients (age 73 ± 12 years, 69% male) 30-day mortality was 11%. Mortality differed significantly among the EHMRG risk groups at 7­day (p = 0.012) and 30-day follow-up (p < 0.01). Based on clinical judgement, 76% of patients were hospitalised. If decision-making had been based on EHMRG, the hospitalisation rate could have been reduced to 66% (p < 0.01), particularly by reducing hospitalisations in patients at low risk of death. Mortality in discharged patients, whether the decision was based on EHMRG or clinical judgement, was 0%. CONCLUSION: The EHMRG accurately differentiates between high- and low-risk decompensated HF patients visiting the ED, making it a promising tool to safely reduce the number of HF admissions.

Time requirements and health effects of participation in colorectal cancer screening with colonoscopy or computed tomography colonography in a randomized controlled trial.

BACKGROUND AND STUDY AIMS: Time limitations and unwanted health effects may act as barriers to participation in colorectal cancer (CRC) screening. The aim of the study was to measure the time requirements and health effects of colonoscopy and computed tomography colonography (CTC) screening. PATIENTS AND METHODS: This was a prospective diary study in a consecutive sample within a randomized controlled CRC screening trial, comparing primary colonoscopy and CTC screening for average-risk individuals aged 50 - 74 years. The diary ended when all screening-related complaints had passed. RESULTS: The diary was returned by 75 % (241/322) of colonoscopy and 75 % (127/170) of CTC screenees. The median interval between leaving home and returning from the examination was longer for colonoscopy (4 hours and 18 minutes [4:18], interquartile range [IQR] 3:30 - 5:00) than for CTC (2:30 hours, IQR 2:06 - 3:00; P < 0.001). Similarly, the time to return to routine activities was longer after colonoscopy (3:54 hours, IQR 1:48 - 15:00) than after CTC (1:36 hours, IQR 0:54 - 4:42). The duration of screening-related symptoms after the examination was shorter for colonoscopy (11:00 hours, IQR 2:54 - 20:00) than for CTC (22:00 hours; IQR 5:30 - 47:00; P < 0.001). Abdominal complaints were reported more frequently after CTC. Anxiety, pain, and quality of life worsened during the screening process, with no differences between the two examinations. CONCLUSIONS: Compared with colonoscopy, CTC screening required less time and allowed screenees to return to their daily activities more quickly. In contrast, CTC was associated with a twofold longer duration of screening-related symptoms. Feelings of anxiety, pain, and quality of life scores were similar during colonoscopy and CTC screening. These results should be incorporated into cost-effectiveness analyses of CRC screening techniques.

Unit costs in population-based colorectal cancer screening using CT colonography performed in university hospitals in The Netherlands.

OBJECTIVES: Computed tomography (CT) colonography cost assumptions so far ranged from 346 to 594 per procedure, based on clinical CT reimbursement rates. The aim of our study was to estimate the costs in a screening situation. METHODS: Data were collected within an invitational population-based CRC screening trial (n = 2,920, age 50-75 years) with a dedicated CT-screening setting. Unit costs were calculated per action, per invitee and per participant (depending on adherence) and per individual with detected advanced neoplasia. Sensitivity analyses were performed, and alternative scenarios were considered. RESULTS: Of the invitees, 47.2 % were reminded, 38.8 % scheduled for an intake, 37.2 % scheduled for CT colonography, 33.6 % underwent CT colonography and 1.1 % needed a re-examination. Lesions ≥ 10 mm were detected in 2.9 % of the invitees. Invitation costs were Euro 5.57. Costs per CT colonography (intake to results) were Euro 144.00. Extra costs of communication of positive results were Euro 9.00. Average costs of invitational-based CT colonography screening were Euro 56.97 per invitee, Euro 169.40 per participant and Euro 2,772.51 per individual with detected advanced neoplasia. CONCLUSIONS: Dutch costs of CT-screening were substantially lower than the cost assumptions that were used in published cost-effectiveness analyses on CT colonography screening. This finding indicates that previous cost-effectiveness analyses should be updated, at least for the Dutch situation.

Age of mother and grandmother in relation to a subject's breast cancer risk.

BACKGROUND: On theoretical grounds, the age of the grandmother and the age of the mother at delivery of her daughter may affect the breast cancer risk of the granddaughter. METHODS: We used the data relating to the Diagnostic Research Mamma-carcinoma cohort (DOM (Diagnostisch Onderzoek Mammacarcinoom) 3), which comprises a population-based sample of 12 178 women aged 41-63 years at enrolment in 1982-85 and followed up until 2000. During follow-up 340 postmenopausal breast cancer cases were identified. To these we applied a case-cohort design together with a random sample from the baseline cohort (n=1826). Of these study participants, we were able to retrieve the birth dates of 998 mothers (309 cases, 689 controls), and for 547 of these we also retrieved the birth dates of the grandmothers (197 cases, 350 controls). A weighted Cox proportional hazards model was used to estimate the hazard ratios (HRs) for the effect of the age of the grandmother and the age of the mother on the breast cancer risk of the index women, while adjusting for potential confounders. RESULTS: Compared with the reference group aged 25-29.9 years, the group with the lowest maternal age (<25 years) had an age-adjusted HR of 0.77 (95% CI 0.19-3.12) and the group with the highest maternal age (> or = 40 years) had an age-adjusted HR of 1.58 (95% CI 0.01-267.81), P-value for trend=0.62. Compared with the same reference group, the group with the lowest grandmaternal age (<25 years) had an age-adjusted HR of 0.53 (95% CI 0.24-1.17) and the group with the highest grandmaternal age (> or = 40 years) had an age-adjusted HR of 7.29 (95% CI 1.20-44.46), P for trend=0.04. The associations did not change significantly after additional adjustment for various risk factors for breast cancer, neither for maternal age nor for grandmaternal age. CONCLUSION: This study does not suggest a major role of maternal age at delivery or grandmaternal age at delivery of the mother for the (grand)daughters' breast cancer risk.

Physical activity is inversely related to waist circumference in 12-y-old French adolescents.

BACKGROUND AND OBJECTIVE: Waist circumference (W) has been shown to be a good predictor of cardiovascular risk. The aim of this study was to investigate whether physical activity (PA) is related to W in adolescents as previously shown in adults. DESIGN AND SUBJECTS: Cross-sectional population-based survey of 2,714 12-y-old adolescents from the eastern part of France. MEASUREMENTS: Body mass index (BMI) and W were measured. Structured PA, active commuting to and from school and sedentary activities (SED), for example television viewing, computer/video games and reading and different potential confounders (dietary habits, parental overweight, family annual income tax and educational level) were assessed by a questionnaire. RESULTS: The adolescents had a mean BMI of 19.0+/-3.4 kg/m2, and 20.2% of them were overweight, with no gender difference. Boys had a greater W than girls (67.6+/-9.1 vs 65.7+/-8.9 cm, P<0.0001). In all, 42% of the girls and 25% of the boys did not practice any structured PA outside school and less than 40% of the adolescents commuted actively to school more than 20 min/day. About one-third of the adolescents devoted more than 2 h/day to SED. In univariate analyses, BMI was negatively associated with structured PA but significantly only for girls (P<0.01) and positively associated with SED for both genders (P<0.0001 for girls, P<0.01 for boys). W was negatively associated with structured PA and positively associated with SED both in girls (P<0.0001 and P=0.03, respectively) and boys (P<0.01 and P=0.08, respectively). Multiple general linear models show that SED is associated with BMI, independently of structured PA, in both genders. On the other hand, structured PA was inversely associated with W, independently of SED. The inverse relation between structured PA and W persisted after additional adjustment on BMI, with a greater effect of PA for the adolescents with higher BMI. CONCLUSIONS: In 12-y-old adolescents, structured PA is inversely associated with W, an indicator of total adiposity but also more specifically of abdominal fat. This suggests that PA may have a beneficial effect on youth metabolic and cardiovascular risks, in particular in the presence of overweight..

Parent-child physical activity relationships in 12-year old French students do not depend on family socioeconomic status.

OBJECTIVES: Regular physical activity (PA) in young needs to be promoted to prevent obesity and subsequent diabetes. Influences of parental PA on adolescents' activity level have been studied with discordant results and the effect of socioeconomic status (SES) on these relationships is not clarified. METHODS: Cross-sectional population-based survey of about 3000 12-year old French students and their parents. Familial associations were assessed with logistic regression models taking into account SES and children's and parents' corpulence. Sport involvement and sedentary behaviors were assessed by standardized questionnaires filled out separately by children and parents, the latter also reporting their educational data and family income tax. RESULTS: Participation in structured PA outside school was higher for boys (74%) than for girls (58%, p<10-5) and a high sedentary behavior (watching television, playing computer/video games and reading > or =2h/day) was observed in one-third of the sample, both in boys and in girls. Children were more likely to participate in structured PA outside school when both parents practiced sport as compared to neither parent practicing it, with an odd ratio OR (95%CI) of 1.97 (1.4-2.8) for boys and 1.56 (1.2-2.1) for girls. Familial associations of inactivity were significant for boys only. A greater percentage of adolescents had a high level of sedentary behavior when both parents versus no parents watched television > 2h/day (OR 1.95 (1.52.6)). Parent-child physical activity relationships were not modified by the family SES or the children's or parents' weight status. CONCLUSION: Parental involvement in sport is an important correlate of a young adolescent's participation in structured PA outside school, whatever the family SES or corpulence of the family members.

Prevalence and sociodemographic determinants of overweight in young French adolescents.

BACKGROUND: The prevalence of overweight in adults and in children is increasing in most industrialised countries. Our purpose is to estimate the prevalence of overweight and obesity in a population of 12-year-old French adolescents and to analyse its association with different sociodemographic factors. METHODS: A cross-sectional study was conducted in 2001 on a representative sample of sixth-grade adolescents (mean age 12.1 +/- 0.6 years) living in the Department of the Bas-Rhin (Eastern part of France). Height and weight were measured in 4326 adolescents. Overweight and obesity were defined as recommended by the International Obesity Task Force. Sociodemographic data were obtained for 3436 adolescents. RESULTS: The prevalence of overweight was 22.7% (17.5% of moderate overweight and 5.2% of obesity) and it was not different by gender or by size of the commune of residence. Overweight was more frequent in low economic zones (p < 10(-4) in girls, p < 10(-2) in boys) and in public schools than in private schools (p < 10(-3) in girls). The prevalence of overweight was inversely associated with family income tax (p < 10(-3) in girls, p = 0.012 in boys), mother's (p = 10(-4) in girls, p = 10(-3) in boys) and father's (p = 0.001 in girls, p = 0.004 in boys) educational level. Multiple logistic regression analysis indicated an independent association of being overweight with low family income tax (p = 0.2195) and poor mother's educational level (p = 0.0193). CONCLUSIONS: This study indicates that, as in other industrialised countries, much overweight and obesity are present in 12-year-old French adolescents. It suggests the existence of an influence of socio-economic factors with a predominant effect of the mother's educational level rather than the financial resources.

[Asthma among children attending kindergarten in Alsace in 1998: prevalence and medical management]. / L'asthme chez les enfants scolarisés en grande section d'école maternelle en Alsace en 1998: prévalence et prise en charge médicale.

UNLABELLED: Asthma is one of the most frequent disease in childhood. The objectives of this survey were to study asthma and asthma related symptoms epidemiology in preschool children and to analyse their medical management. METHODS: A cross-sectional survey was conducted in 1998 in Alsace-France by school doctors, on a randomized sample of 2,765 pupils attending third year kindergarten. The first questionnaire accessed diagnosed asthma and asthma related symptoms history, and school absenteeism. The cumulative prevalence was estimated for diagnosed asthma on the period since birth and for asthma related symptoms unassociated with diagnosed asthma for the past 12 months. Parents who reported diagnosed asthma or asthma related symptoms unassociated with diagnosed asthma of their children were interviewed with a supplemental questionnaire examining clinical patterns, health care and asthma-related hospitalization. RESULTS: Prevalence of asthma was 6.5%. Prevalence of asthma related symptoms unassociated with a diagnosis of asthma was 7.2%. The "chesty" pupils school absenteeism was important. Most of the patients (91.3%) had a mild disease form. One third of them were not getting specific treatment. The drugs mostly prescribed were inhaled bronchodilators for acute episodes of asthma and antihistamines in prophylactic treatment. The rate of asthma-related hospitalization was 11.9%. Severe clinical pattern was statistically related to treatment and asthma-related hospitalization. CONCLUSION: Asthma prevalence is high in children attending nursery school in Alsace. This disease is still nowadays undiagnosed, underinvestigated and undertreated.
