Late morbidity during childhood and adolescence in previously premature neonates after patent ductus arteriosus closure.

The health status of previously premature neonates after closure of a patent ductus arteriosus (PDA) was analyzed in childhood and adolescence. Physician questionnaires were used to study 180 hospital survivors among 210 consecutive premature neonates who underwent PDA closure between 1985 and 2005. Complete follow-up data were obtained for 129 patients (72%). During a median follow-up period of 7 years (range, 2-22 years), three late deaths (2.3%) had occurred. Only 45% of the patients were considered healthy. Morbidity included developmental delay (41.1%), pulmonary illness (12.4%), neurologic impairment (14.7%), hearing impairment (3.9%), gastrointestinal disease (3.1%), and thoracic deformity (1.2%). None of the adverse variables during the neonatal period (intraventricular hemorrhage, bradycardia apnea syndrome, bronchopulmonary dysplasia, pulmonary bleeding, hyaline membrane disease, artificial respiration time [continuous positive airway pressure + intubation], or necrotizing enterocolitis) statistically predicted respective system morbidity at the follow-up evaluation. Hyaline membrane disease (odds ratio, 2.5; p = 0.026) and longer hospitalization time (odds ratio, 1.2 days per 10 hospitalization days; p = 0.032) in the newborn period were significant predictors of an unhealthy outcome at the last follow-up evaluation. Survival until childhood after closure of a hemodynamically significant PDA in premature neonates is satisfactory. However, physical and neurodevelopmental co-morbidity persist for half of the patients, perhaps as a sequela of prematurity unrelated to ductus closure.

Education, disease prevalence and health service utilization in the Swiss National Health Survey "SOMIPOPS".

The relation among education, disease prevalence, and frequency of health service utilization was analyzed using data from the Swiss National Health Survey SOMIPOPS, conducted in 1981-1983 on a randomly selected sample of 4,255 individuals, representative of the entire Swiss population. The prevalence of several important cardiovascular, respiratory, digestive, osteoarticular, and psychiatric disorders was higher among less educated individuals; only allergic conditions were directly associated with indicators of social class. More educated individuals reported lower frequencies of general practitioner visits, but higher frequencies of specialized consultations. These findings confirm that education is an important determinant not only of mortality but also of morbidity and health-care utilization and require careful consideration in terms of the planning and evaluation of health services.

Unobserved heterogeneity and censoring in the demand for health care

This paper analyses the demand for private health care by Spanishhouseholds using a micro budget survey. The methodology used takescare of the three part decision process involved in this type ofbehaviour, namely the decision to use private health care, howoften to do so and how much to spend each time and also the effectsof unobserved heterogeneity. Since the theoretical frameworkcorresponds to the Grossman model of health investment, the resultsalso provide a test of the theory when these issues are considered.Finally, the obtained evidence also suggest that the current systemof tax deductions for private health care expenditures is regressive.

Drug innovation, prices and health

This article tries to reconcile economic-industrial policy with health policy when dealing with biomedical innovation and welfare state sustainability. Better health accounts for an increasingly large proportion of welfare improvements. Explanation is given to the welfare losses coming from the fact than industrial and health policy tend to ignore each other. Drug s prices reflecting their relative relative effectiveness send the right signal to the industry rewarding innovation with impact on quantity and quality of life- and to the buyers of health care services.The level of drug s public reimbursement indicates the social willingness to pay of the different national health systems, not only by means of inclusion, or rejection, in the basket of services covered, but especially establishing the proportion of the price that is going to be financed publicly.Reference pricing for therapeutic equivalents as the upper limit of the social willingness to pay- and two-tiered co-payments for users (avoidable and inversely related with the incremental effectiveness of de drug) are deemed appropriate for those countries concerned at the same time with increasing their productivity and maintaining its welfare state. Profits drive R&D but not its location. There is no intrinsic contradiction between high productivity and a consolidated National Health Service (welfare state) as the European Nordic Countries are telling us every day.

Health correlates of overweight and obesity in adults aged 50 years and over: results from the Survey of Health, Ageing and Retirement in Europe (SHARE)

QUESTIONS UNDER STUDY: To examine the association between overweight/obesity and several self-reported chronic diseases, symptoms and disability measures. METHODS: Data from eleven European countries participating in the Survey of Health, Ageing and Retirement in Europe were used. 18,584 non-institutionalised individuals aged 50 years and over with BMI > or = 18.5 (kg/m2) were included. BMI was categorized into normal weight (BMI 18.5-24.9), overweight (BMI 25.0-29.9) and obesity (BMI > or = 30). Dependent variables were 13 diagnosed chronic conditions, 11 health complaints, subjective health and physical disability measures. For both genders, multiple logistic regressions were performed adjusting for age, socioeconomic status and behaviour risks. RESULTS: The odds ratios for high blood pressure, high cholesterol, diabetes, arthritis, joint pain and swollen legs were significantly increased for overweight and obese adults. Compared to normal-weight individuals, the odds ratio (OR) for reporting > or = 2 chronic diseases was 2.4 (95% CI 1.9-2.9) for obese men and 2.7 (95% CI 2.2-3.1) for obese women. Overweight and obese women were more likely to report health symptoms. Obesity in men (OR 0.5, 95% CI 0.4-0.6), and overweight (OR 0.5, 95% CI 0.4-0.6) and obesity (OR 0.4, 95% CI 0.3-0.5) in women, were associated with poorer subjective health (i.e. a decreased risk of reporting excellent, very good or good subjective health). Disability outcomes were those showing the greatest differences in strength of association across BMI categories, and between genders. For example, the OR for any difficulty in walking 100 metres was non-significant at 0.8 for overweight men, at 1.9 (95% CI 1.3-2.7) for obese men, at 1.4 (95% CI 1.1-1.8) for overweight women, and at 3.5 (95% CI 2.6-4.7) for obese women. CONCLUSIONS: These results highlight the impact of increased BMI on morbidity and disability. Healthcare stakeholders of the participating countries should be aware of the substantial burden that obesity places on the general health and autonomy of adults aged over 50.

Public Health and Health Care Task Force Report, August 2008

The Rebuild Iowa Public Health and Health Care Task Force respectfully submits its report to the Rebuild Iowa Advisory Commission (RIAC) for its consideration of the impacts of the tornadoes, storms, and flooding on Iowans. As the RIAC fulfills its obligations to guide the recovery and reconstruction in Iowa, the impact on the health and well-being of Iowans should be of primary concern. With many areas of the state experiencing devastating damage to their communities, public health and health care are but one of the major challenges. There are critical immediate needs to address the health, safety, and well-being of affected Iowans. This report provides background information on the damages incurred in Iowa from the disasters and additional context for policy and rebuilding discussions. It also offers recommendations to the RIAC for steps that might be taken to address these significant and important challenges.

Organisational innovations and health care decentralisation: A perspective from Spain

Recent policy developments in public health care systems lead to a greater diversity in health care. Decentralisation, either geographically or at an institutional level, is the key force, because it encourages innovation and local initiatives in health care provision. The devolution of responsibilities allows for a sort of de-construction of the status quo by changing both organizational forms and service provision. The new organizations enjoy greater freedom in the way they pay their staff, and are judged according to their results. These organizations may retain financial surpluses, develop spin-off companies and commission a range of specialised services (such as Diagnostic and Treatment Centres in UK) from providers outside the institutional setting in order to have more access to capital markets. However this diversity may generate a feeling of lack of commitment to a national health service and ultimately a loss of social cohesion. By fiscal decentralisation to regional authorities or planned delegation of financial agreements to the providers, financial incentives are more explicit and may seem to place profit-making above a commitment to better health care. An evaluation of the myths and realities of the decentralization process is needed. Here, I offer an assessment pros and cons of the decentralization process of health care in Spain, drawing on the experience of regional reforms from the pioneering organisational innovations implemented in Catalonia in 1981, up to the observed dispersion of health care spending per capita among regions at present.

The impact of Economics on health policy and management in Spain

BackgroundDespite the intrinsic value of scientific disciplines, such as Economics, it is appropriate to gauge the impact of its applications on social welfare, or at least Health Economics (HE) case- its influence on health policy and management.MethodsThe three relevant features of knowledge (production, diffusion and application) are analyzed, more from an emic perspective the one used in Anthropology relying on the experience of the members of a culture- than from an etic approach seated on material descriptions and dubious statistics.ResultsThe soundness of the principles and results of HE depends on its disciplinary foundations,whereas its relevance than does not imply translation into practice- is more linked with the problems studied. Important contributions from Economics to the health sphere are recorded.HE in Spain ranks seventh in the world despite the relatively minor HE contents of its clinical and health services research journals.HE has in Spain more presence than influence, having failed to impregnate sufficiently thedaily events.ConclusionsHE knowledge required by a politician, a health manager or a clinician is rather limited; the main impact of HE could be to develop their intuition and awareness.

Spine Bone Texture Assessed by Trabecular Bone Score (TBS) to Evaluate Bone Health in Thalassemia Major.

Due to the increasing survival of thalassemic patients, osteopathy is a mounting clinical problem. Low bone mass alone cannot account for the high fracture risk described; impaired bone quality has been speculated but so far it cannot be demonstrated noninvasively. We studied bone quality in thalassemia major using trabecular bone score (TBS), a novel texture measurement extracted from spine dual-energy X-ray absorptiometry (DXA), proposed in postmenopausal and secondary osteoporosis as an indirect index of microarchitecture. TBS was evaluated in 124 adult thalassemics (age range 19-56 years), followed-up with optimal transfusional and therapeutical regimens, and in 65 non-thalassemic patients (22-52 years) undergoing DXA for different bone diseases. TBS was lower in thalassemic patients (1.04 ± 0.12 [range 0.80-1.30]) versus controls (1.34 ± 0.11 [1.06-1.52]) (p < 0.001), and correlated with BMD. TBS and BMD values correlated with age, indicating that thalassemia negatively affects both bone quality and quantity, especially as the patient gets older. TBS was 1.02 ± 0.11 [0.80-1.28] in the osteoporotic thalassemic patients, 1.08 ± 0.12 [0.82-1.30] in the osteopenic ones and 1.15 ± 0.10 [0.96-1.26] in those with normal BMD. No gender differences were found (males: 1.02 ± 0.13 [0.80-1.30], females 1.05 ± 0.11 [0.80-1.30]), nor between patients with and without endocrine-metabolic disorders affecting bone metabolism. Our findings from a large population with thalassemia major show that TBS is a valuable tool to assess noninvasively bone quality, and it may be related to fragility fracture risk in thalassemic osteopathy.

Substance P-like-immunoreactive sensory neurons in dorsal root ganglia of the chick embryo: ontogenesis and influence of peripheral targets.

The expression of substance P (SP) was studied in sensory neurons of developing chick lumbosacral dorsal root ganglia (DRG) by using a mixture of periodic acid, lysine and paraformaldehyde as fixative and a monoclonal antibody for SP-like immunostaining. The first SP-like-immunoreactive DRG cells appeared first at E5, then rapidly increased in number to reach a peak (88% of ganglion cells) at E8, and finally declined (59% at E12, 51% after hatching). The fall of the SP-like-positive DRG cells resulted from two concomitant events affecting a subset of small B-neurons: a loss of neuronal SP-like immunoreactivity and cell death. After one hindlimb resection at an early (E6) or late (E12) stage of development (that is before or after establishment of peripheral connections), the DRG were examined 6 days later. In both cases, a drastic neuronal death occurred in the ispilateral DRG. However, the resection at E6 did not change the percentage of SP-like-positive neurons, while the resection at E12 severely reduced the proportion of SP-like-immunoreactive DRG cells (25%). In conclusion, connections established between DRG and peripheral target tissues not only promote the survival of sensory neurons, but also control the maintenance of SP-like-expression. Factors issued from innervated targets such as NGF would support the survival of SP-expressing DRG cells and enhance their SP content while other factors present in skeletal muscle or skin would hinder SP expression and therefore lower SP levels in a subset of primary sensory neurons.

Subjective pubertal timing and health-compromising behaviours among Swiss adolescent girls reporting an on-time objective pubertal timing.

Aim:  The aim of this research is to assess the associations between subjective pubertal timing (SPT) and onset of health-compromising behaviours among girls reporting an on-time objective pubertal timing (OPT). Methods:  Data were drawn from the Swiss SMASH 2002 survey, a self-administered questionnaire study conducted among a nationally representative sample of 7548 adolescents aged 16-20 years. From the 3658 girls in the initial sample, we selected only those (n = 1003) who provided information about SPT and who reported the average age at menarche, namely 13, considering this as an on-time OPT. Bivariate and logistic analyses were conducted to compare the early, on-time and late SPT groups in terms of onset of health-compromising behaviours. Results:  A perception of pubertal precocity was associated with sexual intercourse before age 16 [adjusted odds ratio (AOR): 2.10 (1.30-3.37)] and early use of illegal drugs other than cannabis [AOR: 2.55 (1.30-5.02)]. Conversely, girls perceiving their puberty as late were less likely to report intercourse before age 16 [AOR: 0.30 (0.12-0.75)]. Conclusion:  Faced with an adolescent girl perceiving her puberty as early, the practitioner should investigate the existence of health-compromising behaviours even if her puberty is or was objectively on-time.

Zinc et diarrhées chez les enfants de moins de cinq ans: les recommandations de l'OMS applicables en Suisse [Zinc and diarrhea in children under 5 years: WHO recommendations implemented in Switzerland].

In Europe, acute diarrhea, particularly caused by rotavirus are frequently the cause of epidemics in nurseries, schools, and even hospitals. Studies in many developing countries show that taking 10 to 20 mg per day of zinc for 10 to 14 days, during and after diarrhea, decreases the severity and reduces the number of episodes of diarrhea occurring within 2 to 3 months following the intake of zinc. However, the few studies conducted in developed countries do not confirm or deny its effectiveness in these countries, thereby limiting the global implementation of WHO recommendations for acute diarrhea. The ongoing study at the HEL (Children hospital - Lausanne) aims to promote this additional therapy in children under 5 years of age, perhaps allowing the helvetic application of the new WHO recommendations.
