Cardiovascular and other causes of death as a function of lifestyle habits in a quasi extinct middle-aged male population. a 50-year follow-up study
Objectives: To relate major causes of death with lifestyle habits in an almost extinct male middle-aged population.
Material and methods: A 40-59 aged male population of 1712 subjects was examined and followed-up for 50 years. Baseline smoking habits, working physical activity and dietary habits were related to 50 years mortality subdivided into 12 simple and 3 composite causes of death by Cox proportional hazard models. Duration of survival was related to the same characteristics by a multiple linear regression model.
Results: Death rate in 50 years was of 97.5%. Out of 12 simple groups of causes of death, 6 were related to smoking habits, 3 to physical activity and 4 to dietary habits. Among composite groups of causes of death, hazard ratios (and their 95% confidence limits) of never smokers versus smokers were 0.68 (0.57-0.81) for major cardiovascular diseases; 0.65 (0.52-0.81) for all cancers; and 0.72 (0.64-0.81) for all-cause deaths. Hazard ratios of vigorous physical activity at work versus sedentary physical activity were 0.63 (0.49-0.80) for major cardiovascular diseases; 1.01 (0.72-1.41) for all cancers; and 0.76 (0.64-0.90) for all-cause deaths. Hazard ratios of Mediterranean Diet versus non-Mediterranean Diet were 0.68 (0.54-0.86) for major cardiovascular diseases; 0.54 (0.40-0.73) for all cancers; and 0.67 (0.57-0.78) for all-cause deaths. Expectancy of life was 12 years longer for men with the 3 best behaviors than for those with the 3 worst behaviors.
Conclusions: Some lifestyle habits are strongly related to lifetime mortality
Lifestyle behaviour and lifetime incidence of heart diseases
Objectives: Investigate the relationship of some behavioural characteristics of a male population with lifetime
incidence of heart diseases.
Material and methods: In the Italian Rural Areas of the Seven Countries Study of Cardiovascular Diseases, 1677
heart disease-freemen aged 40–59 yearswere followed up during 50 years for lifetime incidence of heart disease
up to the age of 90 years. They were classified as coronary heart disease (CHD) and heart diseases of uncertain
etiology (HDUE). Baseline cigarette smoking habits (non-smokers and ex-smokers, moderate smokers, heavy
smokers), physical activity (sedentary, moderate, vigorous) and eating habits (non-Mediterranean Diet, Prudent
Diet and Mediterranean Diet) were related to incidence of heart disease.
Results: Incidence of CHD and HDUE up to the age of 90 years was 28.8 and 17.7%, respectively. Univariate and
multivariate analyses showed strong association of behavioural characteristics with CHD incidence, but not
with HDUE incidence. Cox proportional hazard rates for CHD were 1.45 (95% confidence intervals, CI: 1.11–
1.90) for heavy smokers versus non-smokers; 0.67 (CI 0.50–0.89) for vigorous activity versus sedentary habits
and 0.62 (CI 0.47–0.83) for Mediterranean Diet versus non-Mediterranean Diet. Combining CHD cases with
HDUE cases made the predictive picture similar to that of CHD. When some basic risk factors were added to
the model results remained substantially unaltered, despite the existence of some correlations of behaviours
with risk factors.
Conclusions: Behavioural factors including cigarette smoking, physical activity and diet are strong predictors of
lifetime incidence of common heart diseases even adding other traditional risk factors

Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
