Abstract
Objectives. The aim of this study was to analyse the risk of valvular heart diseases among foreign-born individuals in Sweden. Design. This was a nationwide study of individuals aged 18 years of age and older (N = 6,118,649; 2,970,055 men and 3,148,594 women). Valvular heart diseases were defined as at least one registered diagnosis in the National Patient Register between 1 January 1998 and 31 December 2012. Cox regression analysis was used to estimate hazard ratios (HR) with 99% confidence intervals (CI) of incident valvular heart diseases in foreign-born individuals compared to Swedish natives. The Cox regression models were adjusted for age, co-morbidities, and sociodemographic factors. Sub-categories were chronic rheumatic valvular heart diseases and non-rheumatic valvular heart diseases. Results. There were 64,979 male cases and 59,075 female cases. Fully adjusted HRs (99% CI) were among immigrant men 0.86 (0.82-0.89) and immigrant women 0.96 (0.92-1.00). For chronic rheumatic valvular disease among immigrant men and women, the HRs were 1.62 (1.37-1.92) and 1.75 (1.52-2.00), respectively, and, for non-rheumatic valvular disease among immigrant men 0.83 (0.80-0.87) and immigrant women 0.92 (0.88-0.96). Increased risks for chronic rheumatic valvular disease were found among men from Southern, Eastern and Central Europe, Africa and Asia and among women from Western, Eastern and Central Europe and Africa, Latin America and Asia. Conclusions. We observed lower risks in general of valvular heart disease, but higher risks of chronic rheumatic valvular heart disease in immigrants, which is important in the clinical situation.

[PMID: 32039216 PMCID: PMC6992586 DOI: 10.3389/fmed.2019.00328] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2019] [Accepted: 12/19/2019] [Indexed: 11/27/2022] Open
Abstract
Background: Acute rheumatic fever (ARF) remains a major worldwide healthcare problem, despite its progressive decline in developed countries. The aims of our study were to estimate the prevalence of ARF among adolescents in Israel and to investigate risk factors. Methods: The study population consisted of 113,671 consecutive conscripts 16–19 years old, born during 1971–1993, who completed the medical profiling as part of the recruitment process to the IDF. ARF was diagnosed according to Jones criteria at time of illness, with confirmation relying on medical documentation and cardiologist evaluation including echocardiography. Results: The general prevalence rate of ARF was 0.12%. A downward trend was observed, from 0.19% among those born during 1971–1980 to 0.07% among those born during 1981–1993. Differences in prevalence of ARF were noted in sub-populations based on country of birth and origin—Israel, Ethiopia and the former soviet union (FUSSR). The prevalence rates of valvar disease among ARF+ and ARF– recruits were 15.7% and 0.95%, respectively. In multivariable logistic regression analyses, 4 variables were negatively associated with ARF: later birth year group, female gender, rural residence, youngest child; and 3 were positively associated with ARF: young parents, above normal BMI and valvar disease. Conclusion: Our study provides support for the documented decline in ARF prevalence and describes socio-demographic and anthropometric risk factors including the association with valvar disease and novel risk factors including above normal BMI and young parents, both warranting further investigation which might help in developing societal level prevention strategies.

Health Challenges of the Pacific Region: Insights From History, Geography, Social Determinants, Genetics, and the Microbiome. Front Immunol 2019; 10:2184. [PMID: 31572391 PMCID: PMC6753857 DOI: 10.3389/fimmu.2019.02184] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2019] [Accepted: 08/29/2019] [Indexed: 02/06/2023] Open
Abstract
The Pacific region, also referred to as Oceania, is a geographically widespread region populated by people of diverse cultures and ethnicities. Indigenous people in the region (Melanesians, Polynesians, Micronesians, Papuans, and Indigenous Australians) are over-represented on national, regional, and global scales for the burden of infectious and non-communicable diseases. Although social and environmental factors such as poverty, education, and access to health-care are assumed to be major drivers of this disease burden, there is also developing evidence that genetic and microbiotic factors should also be considered. To date, studies investigating genetic and/or microbiotic links with vulnerabilities to infectious and non-communicable diseases have mostly focused on populations in Europe, Asia, and USA, with uncertain associations for other populations such as indigenous communities in Oceania. Recent developments in personalized medicine have shown that identifying ethnicity-linked genetic vulnerabilities can be important for medical management. Although our understanding of the impacts of the gut microbiome on health is still in the early stages, it is likely that equivalent vulnerabilities will also be identified through the interaction between gut microbiome composition and function with pathogens and the host immune system. As rapid economic, dietary, and cultural changes occur throughout Oceania it becomes increasingly important that further research is conducted within indigenous populations to address the double burden of high rates of infectious diseases and rapidly rising non-communicable diseases so that comprehensive development goals can be planned. In this article, we review the current knowledge on the impact of nutrition, genetics, and the gut microbiome on infectious diseases in indigenous people of the Pacific region.
