The global burden of thyroid cancer and its attributable risk factor in 195 countries and territories: A systematic analysis for the Global Burden of Disease Study.

BACKGROUND: Thyroid cancer is a growing threat to human health. Few studies have explored trends of thyroid cancer and relationships with social development factors. In this study, we explored the trend and relationship based on GBD. METHODS: By using GBD study, we obtained detailed data of thyroid cancer. Incidence, mortality and DALY were used to assess epidemiological characteristics. ASR and EAPC were used to estimate the trend. RESULTS: Globally, the incidence significantly increased from 1990 to 2017, especially in high-income regions. Males and middle SDI region demonstrated a higher increase of age-standardized incidence rates. Unlike incidence trend, mortality trend showed a minor increase, and even showed a decreasing trend in some regions such as Eastern Sub-Saharan Africa. Additionally, the DALY trend also demonstrated a slightly increase with an EAPC of 0.77 (95% CI 0.73-0.81). More significant increase of DALY was found in males, middle SDI region and high-income Asia Pacific. The incidence of thyroid cancer peaked in middle-aged people, while the mortality and DALY peaked in elder-aged. Moreover, the proportion of thyroid cancer deaths contributable to high BMI was highest in developed countries and middle-aged people. CONCLUSIONS: Thyroid cancer is a public health problem worldwide. Over-diagnosis might be partly responsible for its rising trend. It remains us to revise the guidelines to avoid unnecessary burdens. Moreover, we should pay attention to the risk factors of thyroid cancer. More targeted measures should be formulated to improve potential environmental and lifestyle-related factors which might contribute to rising trend of thyroid cancer.

Perspectives on the Future of Epidemiology: A Framework for Training.

Over the past century, the field of epidemiology has evolved and adapted to changing public health needs. Challenges include newly emerging public health concerns across broad and diverse content areas, new methods, and vast data sources. We recognize the need to engage and educate the next generation of epidemiologists and prepare them to tackle these issues of the 21st century. In this commentary, we suggest a skeleton framework upon which departments of epidemiology should build their curriculum. We propose domains that include applied epidemiology, biological and social determinants of health, communication, creativity and ability to collaborate and lead, statistical methods, and study design. We believe all students should gain skills across these domains to tackle the challenges posed to us. The aim is to train smart thinkers, not technicians, to embrace challenges and move the expanding field of epidemiology forward.

Epidemiologic Characteristics of Multimorbidity and Sociodemographic Factors Associated With Multimorbidity in a Rapidly Aging Asian Country.

Importance: Multimorbidity is a growing health care problem in aging societies and is strongly associated with epidemiologic characteristics and sociodemographic factors. Knowledge of these associations is important for the design of effective preventive and management strategies. Objectives: To determine the association between multimorbidity and sociodemographic factors (age, socioeconomic status [SES], sex, and race/ethnicity) and the association between mental health diseases and physical diseases, as well as their implications for the types and costs of health care use. Design, Setting, and Participants: This population-based cross-sectional study used deidentified Singapore Eastern Regional Health System data collected between January 1, 2012, and December 31, 2016. Patients who were alive as of January 1, 2016, and residing in the Regional Health System region in 2016 (N = 1 181 024) were included. Patients who had no year of birth records (n = 573), were born in 2017 (n = 93), or died before January 1, 2016 (n = 47 322), were excluded. Main Outcomes and Measures: Multimorbidity, age, sex, SES, mental health, race/ethnicity, and health care use. Results: In the study population of 1 181 024 individuals, the mean (SD) age was 39.6 (22.1) years, 51.2% were women, 70.1% were Chinese, 7.1% were Indian, 13.5% were Malayan, and 9.3% were other races/ethnicities. Multimorbidity, present in 26.2% of the population, was more prevalent in female (26.8%; 95% CI, 26.7%-26.9%) than in male (25.6%; 95% CI, 25.5%-25.7%) patients and among patients with low SES (41.6%) than those with high SES (20.1%). Mental health diseases were significantly more prevalent among individuals with low SES (5.2%; 95% CI, 5.1%-5.2%) than high SES (2.1%; 95% CI, 2.0%-2.1%; P < .001). The 3 most prevalent disease combinations were chronic kidney disease and hypertension, chronic kidney disease and lipid disorders, and hypertension and lipid disorders. Although chronic kidney disease, hypertension, lipid disorders, and type 1 and/or type 2 diabetes-related diseases had a low cost per capita, the large number of patients with these conditions caused the overall proportion of the cost incurred by health care use to be more than twice that incurred in other diseases. Conclusions and Relevance: These findings emphasize the association between multimorbidity and sociodemographic factors such as increasing age, lower SES, female sex, and increasing number of mental disorders. Health care policies need to take sociodemographic factors into account when tackling multimorbidity in a population.

Lessons Learned From an Epidemiologist-Led Countywide Community Assessment for Public Health Emergency Response (CASPER) in Oregon.

CONTEXT: Conducting a large-scale Community Assessment for Public Health Emergency Response (CASPER) in a geographically and linguistically diverse county presents significant methodological challenges that require advance planning. PROGRAM: The Centers for Disease Control and Prevention (CDC) has adapted methodology and provided a toolkit for a rapid needs assessment after a disaster. The assessment provides representative data of the sampling frame to help guide effective distribution of resources. IMPLEMENTATION: This article describes methodological considerations and lessons learned from a CASPER exercise conducted by Washington County Public Health in June 2016 to assess community emergency preparedness. The CDC's CASPER toolkit provides detailed guidance for exercises in urban areas where city blocks are well defined with many single family homes. Converting the exercise to include rural areas with challenging geographical terrain, including accessing homes without public roads, required considerable adjustments in planning. Adequate preparations for vulnerable populations with English linguistic barriers required additional significant resources. Lessons learned are presented from the first countywide CASPER exercise in Oregon. EVALUATION: Approximately 61% of interviews were completed, and 85% of volunteers reported they would participate in another CASPER exercise. Results from the emergency preparedness survey will be presented elsewhere. DISCUSSION: This experience indicates the most important considerations for conducting a CASPER exercise are oversampling clusters, overrecruiting volunteers, anticipating the actual cost of staff time, and ensuring timely language services are available during the event.

Epidemiology: Back to the Future.

In 2018, the Society for Epidemiologic Research and its partner journal, the American Journal of Epidemiology, assembled a working group to develop a set of papers devoted to the "future of epidemiology." These 14 papers covered a wide range of topic areas and perspectives, from thoughts on our profession, teaching, and methods to critical areas of substantive research. The authors of those papers considered current challenges and future opportunities for research and education. In light of past commentaries, 4 papers also include reflections on the discipline at present and in the future.

The making of a population: Challenges, implications, and consequences of the quantification of social difference.

How do we make a difference? This paper traces the connections made between quantified knowledge, population health, and social justice by examining the efforts of population scientists to assess sexuality as a point of difference within population-based data systems, including on national health and social surveys, electronic medical records, and the Census. Population scientists emphasize the importance of measuring social difference in order to identify and remedy structural disadvantage. This evaluation requires the assessment of difference and the comparison of distinct groups across standardized outcome measures. In quantifying social difference, however, population scientists obscure or minimize several difficulties in creating comparable populations. I explore some of these challenges by highlighting three central tensions: the separation of difference from other aspects and categories of social experience, the reduction of difference through the use of one over several possible measures, and the enactment of difference as quantified knowledge loops back into society. As a theoretical inquiry into the form of social difference as it is conceptualized, operationalized, and materialized across the science-society nexus, this paper identifies the various commitments made during processes of scientific evaluation. By attending to the values and priorities that exist within and through practices of quantification, I aim to address the problem of measuring social difference as it pertains to the issues of social justice and health equity.

Apontamentos críticos para o desenvolvimento da vigilância civil da saúde / Critical notes for the development of Health Civil Surveillance

Resumo Apresentam-se, em um ensaio crítico, a ideia e os fundamentos da vigilância civil da saúde. Trata-se de proposta elaborada por Victor Valla na década de 1990, que incorpora à vigilância em saúde a participação da população por meio da educação popular de Paulo Freire. Com o aporte de recursos da Antropologia Interpretativa e da História Nova, faz-se um contraponto entre a vigilância em saúde tradicional, modelada pela vigilância epidemiológica, e a vigilância civil da saúde. Evidenciam-se, então, permanências culturais marcantes na prática da vigilância em saúde desenvolvida hegemonicamente no Brasil. A prerrogativa de cientificidade, que leva à subordinação ao modelo clínico biomédico, a vinculação política à ideia de segurança social e o critério imperativo de urgência, características da vigilância em saúde tradicional, bloqueiam ou dificultam a participação popular. Ao final, vincula-se a vigilância civil da saúde à epistemologia do sul de Boaventura de Sousa Santos. O desenvolvimento da vigilância civil da saúde, que incorpora a participação popular à vigilância em saúde, vem ao encontro das propostas historicamente inscritas na concepção e na evolução da saúde coletiva e do SUS.

Abstract The idea and the grounds for health civil surveillance are presented here in a critical essay. This is a proposal developed by Victor Valla in the 1990s, which incorporates the participation of the population into health surveillance through Paulo Freire's popular education. With the resources input from both interpretative anthropology and the new history, a counterpoint is made between the traditional health surveillance, modelled by the epidemiological surveillance, and the health civil surveillance. Remarkable cultural permanencies in the health surveillance practice hegemonically developed in Brazil are then made clear. The prerogative of scientificity, which brings about the subordination to the biomedical clinical model, the political entailment to the idea of social security and the imperative criterion of urgency, characteristics of the traditional health surveillance, block off or raise difficulties to the popular participation. At the end, the health civil surveillance joins the Southern Epistemology by Boaventura de Sousa Santos. The development of health civil surveillance, which incorporates popular participation into health surveillance, meets the proposals historically inscribed in the collective health and conception and evolution of the SUS.

Communicating Science: The Role of Centers for Disease Control and Prevention's Field-Based Epidemic Intelligence Service Officers, 2009-2014.

CONTEXT: A highly skilled public health workforce is needed for responding to health threats, and that workforce must be able to communicate its scientific findings effectively. OBJECTIVE: We evaluated the scientific communication effectiveness of the Centers for Disease Control and Prevention's (CDC's) field-based Epidemic Intelligence Service officers (EISOs). DESIGN: A descriptive analysis of all scientific information products produced and submitted for institutional clearance by CDC's field-based EISOs during 2009-2014. MAIN OUTCOME MEASURE(S): The number of abstracts, journal manuscripts, Morbidity and Mortality Weekly Reports (MMWRs), and other information products approved by CDC during 2009-2014; the number of those products published; and of those published, the number cited in the scientific literature. RESULTS: During 2009-2014, a total of 152 field-based EISOs produced 835 scientific information products, including 437 abstracts, 261 manuscripts, and 103 MMWRs. The majority of scientific information products submitted for clearance were abstracts (52.3%), and infectious diseases (75.3%) constituted the majority of topics. Among the 103 MMWRs and 261 manuscripts cleared, 88 (85%) and 199 (76%) were published, respectively, with the majority also infectious disease-related. The 199 published manuscripts were cited in the scientific literature 2415 times, and the 88 published MMWRs were cited 1249 times. Field-based EISOs published their work in 74 different peer-reviewed medical and public health journals, with 54% published in journals with impact factors of 1 to 5. CONCLUSIONS: Field-based EISOs' publications are a measurable marker that reflects proficiency in epidemiology, written communication, and professionalism, and those publications are a direct reflection of EISOs' contribution to local and state health departments. Our study establishes a baseline for future evaluations of publication outcome of scientific information products by EISOs. Information released by EISOs provides health professionals with the scientific knowledge necessary for improving their practice and helps CDC achieve a broader societal, environmental, cultural, and economic impact.

Public Health and Epidemiology Informatics: Recent Research and Trends in the United States.

OBJECTIVES: To survey advances in public health and epidemiology informatics over the past three years. METHODS: We conducted a review of English-language research works conducted in the domain of public health informatics (PHI), and published in MEDLINE between January 2012 and December 2014, where information and communication technology (ICT) was a primary subject, or a main component of the study methodology. Selected articles were synthesized using a thematic analysis using the Essential Services of Public Health as a typology. RESULTS: Based on themes that emerged, we organized the advances into a model where applications that support the Essential Services are, in turn, supported by a socio-technical infrastructure that relies on government policies and ethical principles. That infrastructure, in turn, depends upon education and training of the public health workforce, development that creates novel or adapts existing infrastructure, and research that evaluates the success of the infrastructure. Finally, the persistence and growth of infrastructure depends on financial sustainability. CONCLUSIONS: Public health informatics is a field that is growing in breadth, depth, and complexity. Several Essential Services have benefited from informatics, notably, "Monitor Health," "Diagnose & Investigate," and "Evaluate." Yet many Essential Services still have not yet benefited from advances such as maturing electronic health record systems, interoperability amongst health information systems, analytics for population health management, use of social media among consumers, and educational certification in clinical informatics. There is much work to be done to further advance the science of PHI as well as its impact on public health practice.

Charting a future for epidemiologic training.

PURPOSE: To identify macro-level trends that are changing the needs of epidemiologic research and practice and to develop and disseminate a set of competencies and recommendations for epidemiologic training that will be responsive to these changing needs. METHODS: There were three stages to the project: (1) assembling of a working group of senior epidemiologists from multiple sectors, (2) identifying relevant literature, and (3) conducting key informant interviews with 15 experienced epidemiologists. RESULTS: Twelve macro trends were identified along with associated actions for the field and educational competencies. The macro trends include the following: (1) "Big Data" or informatics, (2) the changing health communication environment, (3) the Affordable Care Act or health care system reform, (4) shifting demographics, (5) globalization, (6) emerging high-throughput technologies (omics), (7) a greater focus on accountability, (8) privacy changes, (9) a greater focus on "upstream" causes of disease, (10) the emergence of translational sciences, (11) the growing centrality of team and transdisciplinary science, and (12) the evolving funding environment. CONCLUSIONS: Addressing these issues through curricular change is needed to allow the field of epidemiology to more fully reach and sustain its full potential to benefit population health and remain a scientific discipline that makes critical contributions toward ensuring clinical, social, and population health.

Climate change, human health, and epidemiological transition.

The health of populations depends on the availability of clean air, water, food, and sanitation, exposure to pathogens, toxins and environmental hazards, and numerous genetic, behavioral and social factors. For many thousands of years, human life expectancy was low, and population growth was slow. The development of technology-based civilizations facilitated what Abdel Omran called "epidemiological transition," with increasing life expectancy and rapid population growth. To a large extent, the spectacular growth of human populations during the past two centuries was made possible by the energy extracted from fossil fuels. We have now learned, however, that greenhouse gases from fossil fuel combustion are warming the planet's surface, causing changes in oceanic and atmospheric systems, and disrupting weather and hydrological patterns. Climate change poses unprecedented threats to human health by impacts on food and water security, heat waves and droughts, violent storms, infectious disease, and rising sea levels. Whether or not humanity can reduce greenhouse gas emissions quickly enough to slow climate change to a rate that will allow societies to successfully adapt is not yet known. This essay reviews the current state of relevant knowledge, and points in a few directions that those interested in human health may wish to consider.

A multi-agent-based, semantic-driven system for decision support in epidemic management.

Issues in epidemiology are truly multidisciplinary, requiring knowledge from diverse disciplines such as sociology, medicine, biology, geography and information science. Such inherent complexity has led to a challenge in developing decision support systems for epidemic information management, especially when data are from heterogeneous origins. In order to achieve a solution, an integrative framework is proposed. The Semantic Web is introduced in the context of enriching meaningful and machine-readable descriptions of epidemiological data. Software agents are utilised to achieve automation in semantic discovery, composition of data and process services. The objective is to enhance the performance in information retrieval in a dynamic decision-making environment while concealing technical complexity from inexperienced users. We illustrate how a prototype system can be developed by considering an epidemiology management scenario in which spatio-temporal analysis is undertaken of a specified epidemic.
