Both host and environmental factors are involved in the development of human diseases. Environmental causes of disease include physical, chemical, biological, behavioural, and social factors. Consistent findings in both observational and interventional studies at aggregate and individual levels provide strong evidence of causation between human diseases and environmental agents. They are illustrated by the elucidation of the pleiotropic health effects of arsenic in drinking water and the multifactorial aetiology of hepatocellular carcinoma caused by viral hepatitis. Molecular and genomic biomarkers are used to explore the time-dependent host–environment interaction in the natural history of human diseases. They include dosimetry of exposure to environmental agents; the health outcomes at molecular, cellular, and histological levels; and the genetic and acquired susceptibility. Risk calculators combining multiple biomarkers are developed for the prediction of long-term disease risk. Global partnerships need to be strengthened to achieve interrelated goals of human health, environmental sustainability, and socioeconomic development.

As part of its concern with the environmental causes of disease, medical research tries to comprehend the nature of social processes and their implications for human health: an endeavour calling for sociological concepts and methods (Susser et al, 1985). Medical needs are mirrored within sociology, which has never been confined to study of the workings of society, but has always concerned itself also with their impact on individuals and on public health. The importance of cooperation between the two disciplines is thus indisputable. Nevertheless, interprofessional relationships have never been easy, and Pflanz's dictum, that “the history of the relationship between sociology and medicine is … mainly a history of unsuccessful encounters” (Pflanz, 1976), remains substantially true today. The difficulties have been ascribed to interdisciplinary tensions of the kind that arise when a relatively young academic profession seeks to assert its autonomy in a relationship with an older-established and more powerful one. Martin (1976), stressing the dangers that can result from mutually false expectations, invoked the analogy of a marriage in which:

Background: The increasing incidence of cardiovascular disease (CVD) threatens the Middle Eastern population. Several epidemiological studies have assessed CVD and its risk factors in terms of the primary prevention of CVD in the Middle East. Therefore, summarizing the information from these studies is essential. Aim: We conducted a systematic review to assess the prevalence of CVD and its major risk factors among Middle Eastern adults based on the literature published between January 1, 2012 and December 31, 2018 and carried out a meta-analysis. Methods: We searched electronic databases such as PubMed/Medline, ScienceDirect, Embase and Google Scholar to identify literature published from January 1, 2012 to December 31, 2018. All the original articles that investigated the prevalence of CVD and reported at least one of the following factors were included: hypertension, diabetes, dyslipidaemia, smoking and family history of CVD. To summarize CVD prevalence, we performed a random-effects meta-analysis. Results: A total of 41 potentially relevant articles were included, and 32 were included in the meta-analysis (n=191,979). The overall prevalence of CVD was 10.1% (95% confidence interval (CI): 7.1-14.3%, p<0.001) in the Middle East. A high prevalence of CVD risk factors, such as dyslipidaemia (43.3%; 95% CI: 21.5-68%), hypertension (26.2%; 95% CI: 19.6-34%) and diabetes (16%; 95% CI: 9.9-24.8%), was observed. The prevalence rates of other risk factors, such as smoking (12.4%; 95% CI: 7.7-19.4%) and family history of CVD (18.7%; 95% CI: 15.4-22.5%), were also high. Conclusion: The prevalence of CVD is high (10.1%) in the Middle East. The burden of dyslipidaemia (43.3%) in this region is twice as high as that of hypertension (26.2%) and diabetes mellitus (16%). Multifaceted interventions are urgently needed for the primary prevention of CVD in this region.

The 2008 financial crisis has sparked student demands to rewrite the economics curriculum, giving more space to economic history and the history of economic thought. This can be done within a survey of the main narratives of socioeconomic development. Pre-18th-century discussions of improvement were narratives of linear social progress, however. Once the moderns triumphed over the ancients, the term ‘development’ became common in English. The alternative ‘civilization’ proved to be too ambiguous and too controversial. The development concept bifurcated into ‘organic and constructive versions’, the first with passive (evolutionary) and the latter with active (policy) implications. All development narratives stem from one or the other of these two strands.

Following a long history of using various strategies and policies for diversification and seasonal adjustment in the face of the challenges of achieving economic, social, and environmental sustainability, sun and beach destinations should also consider targeting the wellness tourism market as a post pandemic opportunity and long-term solution. Salou is a mature sun and beach destination in the Mediterranean, but one which, for some time, has had an increasing commitment to family and sports tourism as a result of a strategic renewal process. Now, with the impact of the coronavirus pandemic, the destination management organization is considering the evolution of the model, the internalization of sustainability as a fundamental value, and the impact of different markets. In this study, we examined the challenges the Salou Tourist Board has faced during the development of a post pandemic model for sustainable tourism and what strategies it has adopted in response. We also considered the opportunities and competitive advantages that Salou has in the field of wellness tourism. The results obtained should encourage the continuation of work that promotes the environmental axis of sustainability and adds value to the natural resources on which it depends, including the sea and the landscape, while maintaining the environmental quality of the resources.

In 2010, forty-two million people worldwide were displaced from their homes due to environmental causes. These environmental migrants lack international recognition and have no recourse to the protections of the international refugee regime. This paper examines contradictions inherent in the environmental migration concept, and argues that state-level migration policies related to issues of environmental displacement are reactive and ad hoc in nature. Examining Canadian and US migration policies, this paper demonstrates that national governments have developed a "wait and see" approach towards environmental displacement. With a long history of responding to incidences of displacement, Canada is an important country in terms of its refugee resettlement policies. Accordingly, a review of Canadian refugee policy will provide insights relating to the policy response of western countries to future incidences of environmental displacement.

INTRODUCTION: Current prognostic models of dementia have had limited success in consistently identifying at-risk individuals. We aimed to develop and validate a novel dementia risk score (DRS) using the UK Biobank cohort.METHODS: After randomly dividing the sample into a training (n=166,487, 80%) and test set (n=41,621, 20%), logistic LASSO regression and standard logistic regression were used to develop the UKB-DRS.RESULTS: The score consisted of age, sex, education, apolipoprotein E4 genotype, a history of diabetes, stroke, and depression, and a family history of dementia. The UKB-DRS had good-to-strong discrimination accuracy in the UKB hold-out sample (AUC [95%CI]=0.79 [0.77, 0.82]) and in an external dataset (Whitehall II cohort, AUC [95%CI]=0.83 [0.79,0.87]). The UKB-DRS also significantly outperformed four published risk scores (i.e., Australian National University Alzheimer’s Disease Risk Index (ANU-ADRI), Cardiovascular Risk Factors, Aging, and Dementia score (CAIDE), Dementia Risk Score (DRS), and the Framingham Cardiovascular Risk Score (FRS) across both test sets.CONCLUSION: The UKB-DRS represents a novel easy-to-use tool that could be used for routine care or targeted selection of at-risk individuals into clinical trials.

This article discusses a direction of sociocultural studies – the cultural history of natural resources – and the possibilities of its application in examining the causes of inequality and social exclusion in post-Soviet Lithuania. This theoretical-methodological approach assumes a strong interdependence shared between the extraction of natural resources, a state’s political system and institutions as well as certain sociocultural provisions. In exploring the concept of “internal colonization,” developed by historian of culture Alexander Etkind and other authors, this article sets guidelines for a comparative analysis of the sociopolitical structure of post-Soviet countries (especially Russia and Lithuania). Some initial hypotheses regarding the trends, differences, and similarities of post-Soviet societies in the long historical perspective, from the 16th century up to our time, are presented for further analysis. This article concludes that this methodological approach could be sufficiently promising in explaining the specifics of the socioeconomic development of independent Lithuania, in particular by applying the hypothesis of a “secondary internal colonization,” which has been raised during the course of the investigation.

Simplistic claims about the objectivity of science have been challenged from a variety of perspectives. Evaluation of the external context of production of knowledge and the methodological approaches to posing questions and assembling evidence shows that there is no pure “science”; rather, all scientific knowledge is shaped by the social history of its production. Examples are given of how quantitative concepts in modern epidemiology influence the recognition of the causes of disease. The author uses the phenomenon of intensive swine production by vertically integrated agribusiness to illustrate how broad problems such as environmental racism, agricultural determinants of nutrition, loss of natural resources, and conditions conducive to emergence of new diseases are hidden by epidemiological approaches that fit into corporate policy perspectives. It is critically important to ask who produces epidemiological knowledge, and whose health is promoted by that knowledge.
