Morbidity and mortality in Estonia, Latvia and Lithuania in the 1980's.
1993
The purpose of the present study was to examine the general morbidity and mortality rates in the three Baltic republics — Estonia, Latvia and Lithuania during a decade before the collapse of the Soviet Union. Official statistical data were used to compare morbidity and mortality rates. A method of standardization and life table functions were employed. Soviet morbidity statistics were predominantly descriptive, and based mainly on crude rates registered cases of illness during a year per 100 000 population. The death rates during the Soviet period are a better indicator of the health of the populations than more specific health indicators. A general deterioration of the ecological, social …
Irinotecan (CPT-11) and Mitomycin-C (MMC) as Second-Line Therapy in Advanced Gastric Cancer
2005
Objective The aim of this study was to evaluate the activity and toxicity of a combination regimen of CPT-11 and mitomycin-c as second-line chemotherapy for pretreated patients with advanced, metastatic, or both, gastric adenocarcinoma. Materials and methods Patients with pretreated metastatic disease or early relapsed after adjuvant chemotherapy were enrolled. Entry criteria included histologic/cytologic diagnosis of gastric adenocarcinoma, age 18 to 75 years, performance status > or =70 (Karnofsky scale), bi-dimensionally measurable disease. Patients received CPT-11 and mitomycin-c at the dosage of 150 mg/m2 on days 1 and 15, and 8 mg/m2 on day 1, respectively, every 4 weeks. The disease …
Endarterectomy Versus Angioplasty in Patients with Symptomatic Severe Carotid Stenosis (EVA-3S) trial: results up to 4 years from a randomised, multi…
2008
Summary Background Carotid stenting is a potential alternative to carotid endarterectomy but whether this technique is as safe as surgery and whether the long-term protection against stroke is similar to that of surgery are unclear. We previously reported that in patients in the Endarterectomy Versus Angioplasty in Patients with Symptomatic Severe Carotid Stenosis (EVA-3S) trial, the rate of any stroke or death within 30 days after the procedure was higher with stenting than with endarterectomy. We now report the results up to 4 years. Methods In this follow-up study of a multicentre, randomised, open, assessor-blinded, non-inferiority trial, we compared outcome after stenting with outcome …
Impact of routine angiographic follow-up after angioplasty
1998
Abstract Background There is an ongoing controversy as to whether repeat coronary angiography should be routinely performed after successful percutaneous transluminal coronary angioplasty (PTCA). Methods We examined the 10-year outcome in 400 patients who had or had not undergone an angiographic control 6 months after successful PTCA and a subsequent event-free 6-month period. Our comparison was based on data gathered by questionnaire and telephone interview in 315 patients with (group A) and 85 patients without (group B) a routine 6-month angiographic control. Multivariate analysis (Cox model) was performed to identify predictors of adverse events. Results During the 10-year follow-up peri…
Multidisciplinary treatment of primary Ewing's sarcoma of bone.A 6-year experience of a European cooperative trial
1988
The German Society of Pediatric Oncology in 1981 initiated the Cooperative Ewing's Sarcoma Study (CESS 81) using a four-drug combination of chemotherapy prior to definitive local control with surgery and/or radiation. From January 1, 1981 until February 28, 1985, 93 patients were registered at the trial office from 54 participating institutions in West Germany, Austria, Switzerland, and the Netherlands. On February 1, 1987, 54 of 93 patients were disease-free. Using the Kaplan-Meier life table analysis, the estimated disease-free survival (DFS) rate was 60% at 36 months and 55% at 69 months. The median period of observation was 29 months, ranging from 22 months to 69 months. Twenty-one of 9…
Evaluación de las tarifas de las pensiones de accidentes de trabajo y enfermedades profesionales (2011-2015)
2017
Este trabajo analiza si las tarifas que se aplican para la determinación del denominado capital coste de pensiones derivadas de los accidentes de trabajo y enfermedades profesionales son las adecuadas. A partir de los datos de la Muestra Continua de Vidas Laborales y de la evolución de la longevidad de la población general en España, se estiman tablas de mortalidad para las contingencias de viudedad e invalidez que, combinadas con los parámetros económicos y financieros apropiados, permiten construir las bases técnicas actuarialmente justas para cada uno de los años objeto de análisis. Los resultados obtenidos sugieren que las tarifas aplicadas en el periodo 2011- 2014 han sido muy superior…
Chronic exposure to a GSM-like signal (mobile phone) does not stimulate the development of DMBA-induced mammary tumors in rats: results of three cons…
2002
Certain epidemiological and experimental studies raised concerns about the safety of radiofrequency (RF) electromagnetic fields because of a possible increased risk of leukemia and lymphoma. In this study, an RF field used in mobile telecommunication was tested using 7,12-dimethylbenz[a]anthracene (DMBA)-induced mammary tumors in female Sprague-Dawley rats as a model for human breast cancer. Three experiments were carried out under strictly standardized conditions and were started on the same day of three consecutive years. The field consisted of a GSM-like signal (900 MHz pulsed at 217 Hz, pulse width 577 micros) of relatively low power flux density (100 microW/cm(2) +/- 3 dB) and was appl…
On a Retarded Nonlocal Ordinary Differential System with Discrete Diffusion Modeling Life Tables
2021
In this paper, we consider a system of ordinary differential equations with non-local discrete diffusion and finite delay and with either a finite or an infinite number of equations. We prove several properties of solutions such as comparison, stability and symmetry. We create a numerical simulation showing that this model can be appropriate to model dynamical life tables in actuarial or demographic sciences. In this way, some indicators of goodness and smoothness are improved when comparing with classical techniques.
Testing a new health indicator: using avoidable causes of death and life expectancy for Spain between 1975-1986.
1993
The concept of avoidable cause of death serves as the basis for measuring the quality and diversity of a health care system. In this study the authors propose a new way to use this kind of mortality by combining with the concept of life expectancy to obtain what they call "life expectancy free of avoidable mortality" (LEFAM). This indicator was 76.9 in 1986 in Spain while life expectancy was 75.83. If these deaths were avoidable there would be a gain of 1.09 years per person born. There is an important difference between the would-be male gain of 1.76 years and the would-be female gain of 0.6. In the ecological study, LEFAM would better explain the year to year changes of the resources in t…
Aquatic pollution may favor the success of the invasive species A. franciscana
2015
The genus Artemia consists of several bisexual and parthenogenetic sibling species. One of them, A. franciscana, originally restricted to the New World, becomes invasive when introduced into ecosystems out of its natural range of distribution. Invasiveness is anthropically favored by the use of cryptobiotic eggs in the aquaculture and pet trade. The mechanisms of out-competition of the autochthonous Artemia by the invader are still poorly understood. Ecological fitness may play a pivotal role, but other underlying biotic and abiotic factors may contribute. Since the presence of toxicants in hypersaline aquatic ecosystems has been documented, our aim here is to study the potential role of an…
