Cost-effectiveness analysis of hepatitis B vaccination strategies in Catalonia, Spain 总被引:1,自引:0,他引:1

Hepatitis B virus (HBV) infection is an important public health problem all over the world. Vaccination is one way to prevent it, and several strategies can be used depending on endemicity, the main pattern of HBV transmission and the demographic structure of the population. In this study, an economic comparison of 3 vaccination strategies (mass adolescent vaccination, mass infant vaccination and mass combined vaccination) was performed in Catalonia, Spain. Screening pregnant women for HBV infection in combination with these strategies was also evaluated. Epidemiological models to analyse patterns of HBV infection with and without vaccination and to calculate HBV-associated costs were designed. Comparison between strategies was done using cost-effectiveness analysis from the perspective of the healthcare system. Epidemiological model results indicate that implementation of HBV vaccination could prevent as many as 104,778 new acute infections, and avoid up to 5239 chronic infections, 2096 cases of cirrhosis and 419 cases of hepatocarcinoma over a 20-year period in Catalonia. Cost-effectiveness analysis shows that mass adolescent vaccination is the most efficient strategy, with lower costs per avoided case than the other 2 strategies. When any of these strategies is complemented by screening for HBV in pregnant women, the number of avoided cases is always higher and the cost per avoided case decreases or remains unchanged. 相似文献

With the increasing use of obstetric echography fetal hydronephrosis has been reported more frequently. The purpose of this
study was to identify prognostic factors associated with adverse outcome, such as renal failure and death, in fetal hydronephrosis.
One hundred and forty-eight children with fetal hydronephrosis were admitted, submitted to a systematic protocol, and prospectively
followed. Prognostic factors associated with fetal echography and clinical and laboratory findings on admission were studied.
The median follow-up was 39 months. The analysis was conducted in two steps. In a univariate analysis, variables associated
with adverse outcome were identified by the Kaplan-Meier method. The variables that were significantly associated with adverse
outcome were then included in a multivariate analysis. This analysis, using the multivariate Cox’s model, was performed to
identify variables that were independently associated with a worse prognosis. Only variables that remained independently associated
with adverse outcome were included in the final model. After final adjustment by Cox’s multivariate model, three variables
were identified as independent predictors of adverse outcome: oligohydramnios, prematurity, and glomerular filtration rate
lower than 20 ml/min. Thus, in the presence of oligohydramnios, prematurity, and abnormal renal function, the medical team
must plan appropriate follow-up for infants at health centers prepared to investigate and treat uropathies in newborns.

Preliminary study of electrocautery smoke particles produced in vitro and during laparoscopic procedures 总被引:1,自引:0,他引:1
Background: The objective of this preliminary study was to describe the particles contained in cautery smoke produced during five laparoscopic procedures and verify the collection method during three laboratory experiments on ex vivo animal tissue.
Methods: A cascade impactor collected the smoke according to particle size, and particle weights were calculated on an electronic microbalance. Electron microscopic analysis and energy dispersive X-ray evaluation were used to determine particle morphology and elemental composition.
Results: The particles, distributed according to size on the seven rotating trays of the impactor, had diameters ranging from 0.05 to >25 m, with most being 0.1–1 m. In vitro experiments yielded more particles, especially larger (>5 m) ones, than the surgical procedures, because the cauterized specimens could be placed much closer to the cascade impactor in the laboratory environment, eliminating most obstacles to particle recovery. In the laparoscopic surgery patients, larger particles, because of their physical properties, were more likely to remain trapped in the abdomen or to drop off in the collection apparatus. Uniformly, two populations of particles were demonstrated—either large, irregular fragments (2–25 m) rich in carbon and oxygen, suggesting structural cellular components, or small homogeneous spheres (0.1–0.5 m) composed of sodium, magnesium, calcium, and potassium salts.
Conclusions: This study demonstrates the presence of breathable areosols and cell-size fragments in the cautery smoke produced during laparoscopic procedures. Their exact chemical composition and potential adverse effects for patients and personnel are not known. 相似文献

The effects of amantadine and ketamine were compared to a placebo in a coat-hanger test on lurcher mutant mice. This test measures motor coordination and is dependent on cerebellar functioning. Both drugs improved motor coordination of the cerebellar mutants in that the time taken to reach the side-bar according to a 2 paw criterion was decreased during the drugged condition in comparison to the non-drugged condition. This result indicates that NMDA receptor antagonists may improve motor coordination in animals with cerebellar disease. 相似文献

Practitioners often rely on physiodiagnostic indicators to corroborate the hypothesis of a muscular origin of headache. Although these indicators have been widely applied, their reliability and validity have seldom been tested empirically in headache sufferers. In a controlled double blind study, two trained raters palpated muscle tension and latent and active myogeloses of the left and right trapezius and sternocleidomastoideus muscles and measured passive head rotation flexibility. There were 28 subjects in the study, 14 suffering from tension headache and 14 matched controls. In spite of the training, interrater reliability of ratings concerning degree of muscle tension and number of latent myogeloses proved to be too low to justify subsequent use of these indicators. In keeping with the hypothesis, the various parameters of active myogeloses very clearly differentiated between the experimental groups. The hypothesis turned out not to be true for the parameters of head rotation flexibility. In subjects suffering from tension headache, no correlations could be found between the number of myogeloses of the right trapezius muscle and parameters recorded in long-term EMGs of this muscle, and no correlations could be found between the total number of myogeloses and the chronicity of headache. 相似文献

Seasonality of diarrhetic shellfish poisoning at a coastal lagoon in Portugal: rainfall patterns and folk wisdom. 总被引:3,自引:0,他引:3
Of the three types of toxicity known so far in Portuguese shellfish, only diarrhetic shellfish poisoning (DSP) and amnesic shellfish poisoning (ASP) are produced by microalgae that seem to have been present in the last decades or centuries. The most important paralytic shellfish poisoning (PSP) producer, Gymnodinium catenatum, is hypothesised to have been introduced quite recently as only in 1976 PSP toxicity was detected for the first time in shellfish from Galicia, NW Iberian Peninsula. While ASP presents very short episodes of contamination, the concentration of DSP toxins in some years surpasses human safety values for much longer periods. It is traditionally stated that shellfish should be consumed in 'months with R' (September-April). A retrospective study of the maximum monthly DSP levels attained in mussels from a coastal lagoon-Ria de Aveiro-between 1994 and 2001, showed that the highest frequency of months with concentrations surpassing the safety level of 2 microg/g digestive glands were found in June-September, followed by May and October. These months correspond with the months of lowest historical average rainfall in the period 1941-1998.Oscillations in the rainfall pattern coincided with earliest (or latest) detection by HPLC of DSP toxins in mussel in the years studied. In a semi-closed lagunar environment prone to in situ growth of DSP-producer microalgae, like Dinophysis acuminata, rainfall affects river output, lowering salinity and disrupting water column stability that favours Dinophysis growth. The seasonality of DSP recurrence may be connected to the folk adage on safety of shellfish consumption, after many years of empirical observations by coastal populations of diarrhoea episodes in summertime. 相似文献
