Convergences and divergences in mortality
Abdel Omran's 1971 theory of "Epidemiologic Transition" was the first attempt to account for the extraordinary advances in health care made in industrialized countries since the 18th century. In the framework of the Demographic Transition, it implied a general convergence of life expectancies toward a limit imposed by the new epidemiological features of modern societies. However, important failures, occurred in the past decades (mainly the health crisis in Eastern Europe and AIDS in Africa), seem to have stopped that process of convergence. In fact such failures do not really contradict the theory. The latter is much more ruined by the unexpected dramatic improvement in the field of cardiovascular disease experienced since the seventies, which results in a new step of a more general process. On the basis of the broader concept of “Health Transition†initiated by Julio Frenk et al., the present paper tries to rethink the full process in term of divergence/convergence sequences inferred by successive major changes in health technologies and strategies.cause of death, demographic convergences, epidemiologic transition, health transition, mortality, mortality trends
Examining adherence to activity monitoring devices to improve physical activity in adults with cardiovascular disease: A systematic review
Background
Activity monitoring devices are currently being used to facilitate and monitor physical activity. No prior review has examined adherence to the use of activity monitoring devices amongst adults with cardiovascular disease.
Methods
Literature from June 2012 to October 2017 was evaluated to examine the extent of adherence to any activity monitoring device used to collect objective physical activity data. Randomized control trials comparing usual care against the use of an activity monitoring device, in a community intervention for adults from any cardiovascular diagnostic group, were included. A systematic search of databases and clinical trials registers was conducted using Joanna Briggs Institute methodology.
Results
Of 10 eligible studies, two studies reported pedometer use and eight accelerometer use. Six studies addressed the primary outcome. Mean adherence was 59.1% (range 39.6% to 85.7%) at last follow-up. Studies lacked equal representation by gender (28.6% female) and age (range 42 to 82 years).
Conclusion
This review indicates that current research on activity monitoring devices may be overstated due to the variability in adherence. Results showed that physical activity tracking in women and in young adults have been understudied

Cardiorespiratory Fitness Is Inversely Associated With Clustering of Metabolic Syndrome Risk Factors: The Ball State Adult Fitness Program Longitudinal Lifestyle Study
Objective: The focus of this study was the association between the metabolic syndrome (MetSyn) and cardiorespiratory fitness (CRF) defined as maximal oxygen uptake (VO2max). Although previous research has shown a relationship between MetSyn and CRF, most studies are based on less objective measures of CRF and different cardiometabolic risk factor thresholds from earlier guidelines
The optimal treatment of multivessel coronary artery disease
The practice of percutaneous coronary intervention has overtaken coronary bypass surgery in the treatment of ischaemic heart disease. Several randomized controlled as well as registry and observational trials have addressed the issue of patient selection and outcomes in order to provide the cardiologist with data enabling optimal treatment selection. This article reviews the major trials performed over the past 25 years, underscoring their strengths and limitations and draws on lessons and guidelines that are relevant to our local practice.peer-reviewe
Recovery from repeated sudden hearing loss in a patient with Takayasu’s arteritis treated with hyperbaric oxygen therapy: the first report in the literature
Hearing loss has been rarely reported in Takayasu's arteritis, presents as sudden sensorineural hearing loss and usually responds well to corticosteroid therapy. Hyperbaric Oxygen Therapy is commonly used as a supplementary treatment to corticosteroids for sudden hearing loss. We present the case of a woman with Takayasu's arteritis who had two episodes of hearing loss involving one ear at a time with a 11-month delay between each episode. During the first episode, the patient was treated with high-dose intramuscular corticosteroids with a temporary improvement of auditory threshold, that deteriorated close to previous level 14 days after cessation of therapy. In the second episode, Hyperbaric Oxygen Therapy was associated to corticosteroids, with a significant, longer term improvement in both ears, including the one that had shown to be unresponsive to previous pharmacologic therapy. Oxygen therapy could have played a role in hearing restoration in this patient, as it could have acted synergically with corticosteroids amplifying their effect
06-05 Can Climate Change Save Lives? A comment on “Economy-wide estimates of the implications of climate change: Human health”
In a recent article in this journal, Francesco Bosello, Roberto Roson, and Richard Tol make the surprising prediction that the first stages of global warming will, on balance, save a large number of lives. Bosello et al. fail to substantiate this remarkable estimate, and they make multiple mistaken or misleading assumptions. They rely on research that identifies a simple empirical relationship between temperature and mortality, but ignores the countervailing effect of human adaptation to gradual changes in average temperature. While focusing on small changes in average temperatures, they ignore the important health impacts of extreme weather events such as heat waves, droughts, floods, and hurricanes. They extrapolate this pattern far beyond the level that is apparently supported by their principal sources, and introduce an arbitrary assumption that may bias the result toward finding benefits from warming.
