HEMATOLOGICAL VARIABILITY ANALYSIS AFTER ROAD MARATHON VS ULTRATRAIL. PREDICTIVE FACTORS
2020
The practice of long- and medium-distance races has exponentially increased the number of participants in recent years. They are carried out under extreme conditions that cause both biochemical and anthropometric changes in athletes and, in addition, have serious risks associated, such as dehydration, thermal disorders, or hypoglycemia. Knowledge regarding alterations at hematological level after this type of effort is limited. The objectives of this pre-post analytical descriptive observational study were: to describe and compare hematological values in amateur runners pre and post road marathon and ultratrail races, and to compare the hematological parameters between the groups in the two…
El Instituto Médico Valenciano y la difusión de la vacuna
2004
The Medical Valencian Institute promoted a campaign of smallpox free vaccination (1851- 1894) by means of humanized vaccine sent from England. It spread the vaccination for the whole Spain and published careful statistics of the vaccinations practised in the Bulletin of the Medical Valencian Institute. The National Institute of Vaccination (1871) did not recognize his labor and one denied to him the category of Provincial Institute of Vaccination.
Prevalence of hypovitaminosis D in elderly women in Italy: clinical consequences and risk factors
2002
In order to evaluate the prevalence, risk factors, and clinical consequences of hypovitaminosis D in elderly Italian women a multicenter study of 43 osteoporosis centers from all regions of Italy was carried out. Study population included 700 women aged 60-80 years in whom blood was taken for 25-hydroxyvitamin D (25OHD) and parathyroid hormone (PTH) measurements. All subjects were also questioned to assess the prevalence of several risk factors for hypovitaminosis D, osteoporotic fractures and activities of daily living (ADL). Values of 25OHD lower than 5 ng/ml were found in 27% of the women and lower than 12 ng/ml in 76%. 25OHD and PTH levels were negatively correlated ( r=-0.38, after log…
Need for Orthodontic Treatment in Pupils Aged between 12 and 15 in the Valencian Region (Spain)

The World Health Organization recommends carrying out periodic epidemiological studies in order to provide a basis for the evaluation of the state of health of the population at any given time
The seroepidemiology of pertussis in Australia during an epidemic period
2006
Studying the epidemiology of pertussis and impact of differing vaccine schedules is difficult because of differing methods of case ascertainment. The advent of internationally standardized serological diagnosis for recent infection has allowed comparison of age-specific pertussis infection among European countries and was applied in Australia at the time of a major national epidemic. In 1997 and 1998, a nationally representative serum bank using residual sera from diagnostic laboratories was established. Measurement of pertussis toxin (PT) IgG level was conducted by a reference laboratory using an enzyme-linked immunosorbent assay standardized for a number of European countries. A titre of …
Anthropometric and physical characteristics allow differentiation of young female volleyball players according to playing position and level of exper…
2017
The aim of our study was to determine the differences in some anthropometric and physical performance variables of young Croatian female volleyball players (aged 13 to 15) in relation to playing position (i.e., independent variable) and performance level within each position (i.e., independent variable). Players were categorized according to playing position (i.e., role) as middle blockers (n=28), opposite hitters (n=41), passer-hitters (n=54), setters (n=30), and liberos (n=28). Within each position, players were divided into a more successful group and a less successful group according to team ranking in the latest regional championship and player quality within the team. Height and body …
Epidemiological Measures in the Context of the COVID-19 Pandemic.
2020
BACKGROUND: The various epidemiological indicators used to communicate the impact of COVID-19 have different strengths and limitations. METHODS: We conducted a selective literature review to identify the indicators used and to derive appropriate definitions. We calculated crude and age-adjusted indicators for selected countries. RESULTS: The proportion of deaths (case fatality proportion [CFP]; number of deaths/total number of cases) is commonly used to estimate the severity of a disease. If the CFP is used for purposes of comparison, the existence of heterogeneity in the detection and registration of cases and deaths has to be taken into account. In the early phase of an epidemic, when cas…
Why Does COVID-19 Case Fatality Rate Vary Among Countries?
2020
SummaryBackgroundWhile the epidemic of SARS-CoV-2 is spreading worldwide, there is much concern over the mortality rate that the infection induces. Available data suggest that COVID-19 case fatality rate varies temporally (as the epidemic progresses) and spatially (among countries). Here, we attempted to identify key factors possibly explaining the variability in case fatality rate across countries.MethodsWe used data on the temporal trajectory of case fatality rate provided by the European Center for Disease Prevention and Control, and country-specific data on different metrics describing the incidence of known comorbidity factors associated with an increased risk of COVID-19 mortality at …
Optimization of hepatitis C virus screening strategies by birth cohort in Italy
2020
Abstract Background and Aims Cost‐effective screening strategies are needed to make hepatitis C virus (HCV) elimination a reality. We determined if birth cohort screening is cost‐effective in Italy. Methods A model was developed to quantify screening and healthcare costs associated with HCV. The model‐estimated prevalence of undiagnosed HCV was used to calculate the antibody screens needed annually, with a €25 000 cost‐effectiveness threshold. Outcomes were assessed under the status quo and a scenario that met the World Health Organization's targets for elimination of HCV. The elimination scenario was assessed under five screening strategies. Results A graduated birth cohort screening strat…
Tendencias de la mortalidad por cáncer en españa, en especial del cáncer de pulmón, en comparación con otros países desarrollados
1994
ResumenSe estudia la evolución de la mortalidad global por cáncer en España (1970–1987), y especialmente por cáncer de pulmón, por sexos y grupos de edad, estableciendo comparaciones con otros países (EEUU, Inglaterra y Gales).En cuanto a la evolución de la mortalidad global por cáncer se observa que únicamente en las edades más juveniles se detectan descensos notables de la mortalidad, en tanto que, en los otros países con los que se compara, se observa también una disminución en edades más avanzadas. Asimismo, aunque las tasas de mortalidad por cáncer de pulmón en España tienen unos valores inferiores a los de los países mencionados, se observa un incremento de la mortalidad de ambos sexo…
