Veränderung von Inzidenz und Mortalität von Kopf-Hals-Malignomen in Rheinland-Pfalz, 2000–2009
2014
Hintergrund: Epidemiologische Daten zu Kopf-Hals-Malignomen werden trotz ihrer anatomisch-histologischen Heterogenitat oft aggregiert berichtet. In Deutschland gibt es bisher nur wenige Studien, die Trends von Inzidenz und Mortalitat detailliert nach Tumorentitaten analysiert haben. Weiterhin ist wenig daruber bekannt, ob die Inzidenz von HPV-assoziierten Tumorentitaten der Kopf-Hals-Region zugenommen hat. Methoden: Anhand von Krebsregisterdaten aus Rheinland-Pfalz von 2000–2009 wurden altersstandardisierte Inzidenz- und Mortalitatsraten fur alle Kopf-Hals-Tumorentitaten einzeln und nach Lokalisationsgruppen, die HPV-assoziiert sein konnten, berechnet. Zeitliche Trends wurden mittels Joinpo…
The Correlation between Adolescent Daily Breakfast Consumption and Socio-Demographic:Trends in 23 European Countries Participating in the Health Beha…
2023
Breakfast is often considered the most important meal of the day and can benefit adolescent health in several ways. The aims of the present study were (1) to identify adolescents’ socio-demographic (sex, family affluence and family structure) determinants of daily breakfast consumption (DBC) and (2) to describe trends in DBC among adolescents across 23 countries. Cross-sectional surveys of nationally representative samples of adolescents (aged 11, 13, and 15 years) (n = 589,737) participating in the Health Behaviour in School-aged Children (HBSC) survey from 2002 to 2018 were used. Multilevel logistic regression analyses modeled DBC over time, adjusted for family affluence, family structure…
The academic field of Sport Management: past, present and future
2019
The industry of sport currently has a big impact on our society, in areas as diverse as economics, mass media, health or politics. As a result of this new trend, a specific academic field, identified as ‘Sport Management’ has emerged in the past years. A study field that appears to have experienced a substantive growth over a short period of time. This paper has conducted a review on the relevant aspects that have shaped the identity of Sport Management as an academic field. For that purpose, documentary sources have been used as reference with a main focus in those produced by relevant authors of the Sport Management field, granting special attention to the theoretical construction of the …
The role of humidity in associations of high temperature with mortality: A multicountry, multicity study
2019
BACKGROUND: There is strong experimental evidence that physiologic stress from high temperatures is greater if humidity is higher. However, heat indices developed to allow for this have not consistently predicted mortality better than dry-bulb temperature. OBJECTIVES: We aimed to clarify the potential contribution of humidity an addition to temperature in predicting daily mortality in summer by using a large multicountry dataset. METHODS: In 445 cities in 24 countries, we fit a time-series regression model for summer mortality with a distributed lag nonlinear model (DLNM) for temperature (up to lag 3) and supplemented this with a range of terms for relative humidity (RH) and its interaction…
Is Big Brother Watching Us? Google, Investor Sentiment and the Stock Market
2013
International audience; This paper proposes a novel measure of French investor sentiment based on the volume of internet search reported by Google Trends. We find that our sentiment indicator correlates well with alternative sentiment measures often used in the literature. Furthermore, we find that investor sentiment influences the behavior of mutual fund investors. The results also reveal evidence about short-run predictability in return. An increase in our sentiment index leads to short-term return reversal. The reversal pattern is more pronounced for smaller firms than larger firms, consistent with the predictions of noise trader's models.
Medida del resultado de las intervenciones sanitarias en España: una aproximación mediante el análisis temporal y espacial de la mortalidad evitable …
2006
Fundamento: Muchos estudios proponen la mortalidad evitable (ME) como indicador para monitorizar los servicios de salud aunque su generalización está limitada por el gran número de listas de causas utilizadas. El objetivo es analizar la evolución temporal del período 1986-2001 y la distribución geográfica de la mortalidad evitable utilizando una lista de causas consensuada. Métodos: Se analiza la mortalidad evitable global (ME) y agrupada en causas ISAS (intervenciones de los servicios sanitarios) y causas IPSI (políticas intersectoriales). Se analiza la evolución temporal ajustando una recta de regresión de Poisson o un modelo de regresión de Joinpoint, según el caso, y se estima el porcen…
Climate and land-use changes as determinants of lesser kestrel Falco naumanni abundance in Mediterranean cereal steppes (Sicily)
2010
Monitoring of lesser kestrels Falco naumanni is necessary to promote conservation of this vulnerable species. To this end, 35 colonies of this species located in the NNW and SE of Sicily were monitored from 2003 to 2009. Counts of the active colonies and resident pairs were modelled by loglinear Poisson regressions to assess population trends over the study period. Afterwards, a GLM with an analysis of covariance design and a backward removal stepwise regression was performed to relate the observed trend to local- or global-scale climatic variation and to local land-use changes. Colony counts provided a better fit to the loglinear models than pair counts. Loglinear models separated the incr…
An analysis of botanical studies of vascular plants from Italian wetlands
2022
Wetlands are essential for life on Earth, but at the same time the most threatened environments due to the gradual alterations associated with climate change and human action. The botanical studies on wetland higher plants carried out in Italy from 1950 until today are analysed in this survey. The 1,265 contributions resulting from this study are analysed from a historical, geographical, and content point of view. Most of the scientific contributions were published in the 1980s and 1990s, often by the same research groups and on a local scale. The predominant research theme is the inventory. Most papers are mainly focused on lakes and rivers. The results of this literature survey point to t…
Pediatric bone tumors in Germany from 1987 to 2011: incidence rates, time trends and survival
2016
AbstractBackground: Malignant bone tumors are a rare group of childhood cancer.Materials and methods: This study describes incidence rates, survival probabilities, and time trends for 1831 children below 15 years of age with a bone tumor registered at the population-based German Childhood Cancer Registry between 1987 and 2011.Results: Overall age-standardized annual incidence rate (ASR) was 5.5 per million. Osteosarcomas (ASR 2.8) and Ewing tumors (ASR 2.6) were the most frequent diagnostic groups. The incidence of bone tumors overall tended to increase slightly over time by 0.7% each year on average. Thirty-nine of the bone tumor cases reported were subsequent primaries and not included in…
International Trends in Adolescent Screen-Time Behaviors From 2002 to 2010
2016
Abstract Purpose Engaging in prolonged screen-time behaviors (STBs) is detrimental for health. The objective of the present analyses was to examine temporal trends in TV viewing and computer use among adolescents across 30 countries. Methods Data were derived from the cross-national Health Behaviour in School-aged Children study. Data on TV viewing and computer use for gaming and nongaming purposes were collected in 2002 (n = 139,725 [51.4% girls]), 2006 (n = 149,251 [51.3% girls]), and 2010 (n = 154,845 [51.2% girls]). The temporal trends in TV viewing and computer use were each tested for all countries combined and for each individual country by sex-specific univariate analysis of varianc…
