Introduction and objectives
This article describes the contribution of the decrease in cardiovascular mortality to the increase in life expectancy at birth in Spain from 1980 to 2009. We explain the demographic factors underlying the decrease in mortality from cardiovascular diseases at older ages and the effect of this decrease on lifespan.Methods
The contribution of these decreases to Spanish life expectancy at birth was calculated using decomposition methods for life expectancy. We calculated standardized mortality rates by sex and 3 causes of death (cerebrovascular disease, ischemic heart disease, and other heart disease) for 3 age groups: 65 to 79 years, 80 to 89 years, and ≥90 years.Results
From 1980 to 2009, life expectancy at birth in Spain increased by more than 6 years for both sexes. The contribution of the decrease in cardiovascular mortality to the total increase in life expectancy at birth was 63% among women and 53% among men. Among the ≥65-year-old age group, this contribution was 93% among women and 87% among men.Conclusions
The decrease in cardiovascular mortality, mainly at older ages, has been the main contributor to increased Spanish life expectancy at birth during the last 3 decades.Full English text available from:www.revespcardiol.org/en 相似文献6.

FDG-PET, now hybrid positron emission tomography/computed tomography (PET-CT), has become an established diagnostic tool in oncology. Fluorodesoxyglucose (18F-FDG) is not specific for malignant lesions, as uptake of the tracer depends on its accumulation in cells with an increased glucose metabolism as it is also the case in infectious and inflammatory lesions, like sarcoidosis. Thus, FDG-PET has been proposed for internal medicine indications, one of whom is sarcoidosis. The main characteristics of FDG-PET are its better sensitivity compared to 67Ga scintigraphy and its ability to be used as an earlier marker of therapeutic response as compared with anatomy-based and conventional scintigraphic imaging. However, FDG-PET should be used in atypical or advanced stage of the disease. Future prospective studies should be awaited before integrating FDG-PET in clinical routine for treatment outcome and disease activity assessment in sarcoidosis. New radiopharmaceutical probes are under development and will improve the performance of PET. 相似文献

Malignant tumors account for 1% of childhood cancers. The incidence is to the order of 122 cases per million children. The five-year survival after cancer before the age of 16 years has improved from 50 to 80% in 40 years. Assessment of potential for preservation of fertility should thus be a systematic element of care for children treated for a malignant tumor (high-dose chemotherapy with alkylizing agents, radiation therapy including the gonads) or those receiving hematopoietic stem cell grafts for malignant or benign disease (sickle-cell anemia, immune deficit). Among the techniques proposed, cryopreservation of ovarian tissue appears to be the most promising, or perhaps the only one available before puberty with encouraging result. Nevertheless the uncertainties, or even risks, related to these treatments, should not be neglected. 相似文献

Background
Patients with cerebral infarction often present impaired consciousness and unsatisfactory extubation. We aimed to assess the respiratory mechanics components that might be associated with the success of extubation in stroke patients.Methods
Twenty consecutive patients with stroke who needed mechanical ventilation support were enrolled. The maximal inspiratory pressure, gastric and the esophageal pressure (Pdi/Pdimax), minute volume, respiratory rate, static compliance, airway resistance, rapid and superficial respiration index (RSRI), inspiratory time/total respiratory cycle (Ti/Ttot), and PaO2/FiO2 were measured.Results
The group who presented success to the extubation process presented 12.5 ± 2.2 = days in mechan-ical ventilation and the group who failed presented 13.1 ± 2 = days. The mean Ti/Ttot and Pdi/Pdimax for the failure group was 0.4 ± 0.08 (0.36-0.44) and 0.5 ± 0.7 (0.43-0.56), respectively. The Ti/Ttot ratio was 0.37 ± 0.05 (0.34-0.41; p = 0.0008) and the Pdi/Pdimax was 0.25 ± 0.05 for the success group (0.21-0.28; p < 0.0001). A correlation was found between Pdi/Pdimax ratio and the RSRI (r = 0.55; p = 0.009) and PaO2/FiO2 (r = −0.59; p = 0.005). Patients who presented a high RSRI (OR, 3.66; p = 0.004) and Pdi (OR, 7.3; p = 0.002), and low PaO2/FIO2 (OR, 4.09; p = 0.007), Pdi/Pdimax (OR, 4.12; p = 0.002) and RAW (OR, 3.0; p = 0.02) developed mechanical ventilation extubation failure.Conclusion
Muscular fatigue index is an important predicting variable to the extubation process in prolonged mechanical ventilation of stroke patients. 相似文献14.

Despite the introduction of protease inhibitors (PI) in the treatment of hepatitis C, the sensitivity of interferon continues to be essential to achieve a sustained virological response (SVR) and to eradicate the viral infection. Currently, pegylated interferon (PEG-IFN) and ribavirin (RBV) are required to avoid selection of PI-resistance mutations. The likelihood of obtaining an SVR with dual therapy in treatment-naïve patients with genotype 1 infection varies from 40% to 50%. That is, almost half of these patients would not require a PI, thus avoiding their adverse effects and considerably reducing the cost of the treatment. Identifying which patients could potentially respond to dual therapy is one of the main challenges in clinical practice. The genetic variability of the host is one of the main factors affecting the sensitivity of PEG-IFN and therefore in the response to current treatment. Other baseline factors related to the host, the virus and, especially, to intratreatment factors such as rapid virological response (RVR) are strongly associated with the probability of achieving an SVR. The evidence on the decision to prescribe dual or triple therapy according to the factors predictive of response is based on retrospective studies or post-hoc analyses of pivotal studies on PI. Study of the polymorphisms of the IFNL3 gene (IL28B), ITPA, IFN-stimulated genes (ISGs), TT/ΔG (ss469415590; IFNL4)) and RBV transporters could help in the decision to prescribe dual or triple therapy in treatment naïve patients. 相似文献

Aim of the study
MALDI-TOF mass spectrometry (MS) is becoming a major resource in the Clinical Microbiology laboratory. Results on some groups of microorganisms are still controversial. We have studied the reliability of MALDI-TOF MS for the identification of anaerobic clinical isolates was studied compared to conventional biochemical methods, with rRNA 16S sequencing being used as a reference when discrepancies arose.Material and methods
A total of 126 anaerobic bacteria clinical isolates were studied by using API20A kits (bioMérieux, Marcy l’Étoile, France) and MALDI-TOF MS (Autoflex II, Bruker Daltonics, Germany), and using the data library BioTyper 2.0 (Bruker Daltonics, Germany). When discrepancies arose, or MALDI-TOF MS was not able to identify any microorganism, rRNA 16S sequencing was used as the reference standard.Results
The biochemical method and MALDI-TOF MS agreed in identifying 60.9% of isolates at species level, and 20.3% of isolates at genus level. Among the 48 discrepancies observed, rRNA 16S sequencing supported MALDI-TOF MS identification, at species level, in 32 isolates (66.7%), and in 8 isolates (16.7%) at genus level. rRNA 16S sequencing supported biochemical identification in only two isolates (4.2%) at species level, and in 26 isolates (54.2%) at genus level. The eight isolates for which MALDI-TOF MS did not manage to identify, or the identification obtained was rejected by sequencing, belonged to species that are still not added to the BioTyper II data library.Conclusions
Results obtained in this study show that, overall, MALDI-TOF MS identification of anaerobic bacteria is more reliable than identification obtained by conventional biochemical methods (24% more correct identifications at species level). The number of major errors (incorrect identification at the genus level) is also 2.5-times lower. Moreover, all the major errors obtained by MALDI-TOF MS were due to the absence of some species in the data library. Thus, when data libraries are more complete, reliability differences between both methods will probably be even higher. 相似文献18.
