Online community collaborative map: A geospatial and data visualization tool for cancer data.

The aim of this study was to develop an online collaborative map to enable researchers to locate, explore, and share cancer data.This 2-scale (global and country-level) cancer map adopts a database-driven model, which was implemented using the Google Map Application Programming Interface (API) and asynchronous JavaScript and XML (AJAX) technology. Seven visualization techniques were used to present data. Data on worldwide cancer mortality between 1950 and 2013 were taken from the International Agency for Research on Cancer (IARC) database. Incidence data were from the IARC CI5plus database. Survival data were from the IARC SURVCAN study. Prevalence data between 1990 and 2017 were from the Institute for Health Metrics and Evaluation's (IHME) catalog while demographic data were from the World Bank Data Catalog. Cancer data for Taiwan between 1991 and 2016 were obtained from the Department of Health and Welfare. This study used visualization techniques that included: a choropleth map to display the prevalence of cancer; a tornado diagram to show the age-standardized mortality rates of all cancers among men and women in 2013; a treemap to show a ranking of cancer mortality data; a sunburst chart to show mortality rates of all cancers by gender; a line chart to show mortality trends for all cancers; a bar chart to show mortality and incidence rates and a heatmap to show variations in cancer across different countries.The world cancer map generated by this study can be accessed at http://worldmap.csmu-liawyp.tw. Country-level mortality data are presented as crude and age-standardized rates.We used visualization methodologies and constructed an easily maintainable web-based user interface with cancer data from administrative regions in 150 countries. This serves as a platform that allows researchers to manage and disseminate cancer data.

Funnel plots and choropleth maps in cancer risk communication: a Delphi study.

BACKGROUND: In the last decades, the issues related to health risk communication to stakeholders and citizens involving health care practitioners and local political authorities have been increasingly debated. The study evaluated an alternative strategy to communicate cancer risk to local communities, involving an expert panel of public health operators in comparing two different graphic tools, Funnel Plot and Choropleth map. STUDY DESIGN: A Delphi method process was implemented to achieve a unified consensus on an expert panel of public health operators with regard to weaknesses and strengths of the Funnel Plot and the Choropleth map as tools for cancer risk communication to local communities and other stakeholders. METHODS: Participants were asked to score the efficacy of the two tools using a scale. Six properties were explored through two consecutive consensus rounds. Scales were used to calculate frequencies and the content validity ratio for each domain within the consensus rounds. RESULTS: After the two consecutive rounds, participants expressed their preference in favour of the Choropleth map for its ability to define the spatial location of the risk and to locate any potential cluster, while reaching a consensus with regard to the Funnel Plot properties to identify hot spots, displaying the scope of the phenomenon under investigation, and to show the precision of estimates and communicating the significance of estimates. CONCLUSIONS: The Delphi process allowed us to conclude that Funnel Plot could be used as a complement to the current and commonly used graphical and visual formats to effectively communicate cancer epidemiological data to communities and local authorities, representing a useful tool for empowering the general population.

Message in a bottle: the discovery of a young medical officer's map from the 1917 Battle of Hill 70

Summary: We report the serendipitous discovery of a map drawn by an army surgeon during the First World War. The map, entitled "Loos 36° NW3,'"was drawn by 24-year-old Captain Alexander Edward MacDonald in fall 1917 and was found in his old surgery textbook. MacDonald's map depicts the positions of Canadian frontlines and medical units after the Battle of Hill 70. During the battle, Dr. MacDonald tended to the wounded in an aid post that he constructed in a ruined coal mine near the Front. MacDonald would go on to serve with distinction in the Battle of Passchendaele and Canada's Hundred Days, and he received the Military Cross for gallantry. He maintained a passionate interest in cartography throughout his life and eventually became an authority among map collectors. Artifacts such as MacDonald's map remind us of the realities of war and the sacrifices of our surgeon predecessors.

Mapping of radio frequency electromagnetic field exposure levels in outdoor environment and comparing with reference levels for general public health.

In this study, radio frequency electromagnetic field exposure levels were measured on the main streets in the city center of Diyarbakir, Turkey. Measured electric field levels were plotted on satellite imagery of Diyarbakir and were compared with exposure guidelines published by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). Exposure measurements were performed in dense urban, urban and suburban areas each day for 7 consecutive days. The measurement system consisted of high precision and portable spectrum analyzer, three-axis electric field antenna, connection cable and a laptop which was used to record the measurement samples as a data logger. The highest exposure levels were detected for two places, which are called Diclekent and Batikent. It was observed that the highest instantaneous electric field strength value for Batikent was 7.18 V/m and for Diclekent was 5.81 V/m. It was statistically determined that the main contributor band to the total exposure levels was Universal Mobile Telecommunications System band. Finally, it was concluded that all measured exposure levels were lower than the reference levels recommended by ICNIRP for general public health.

No âmago da africanização: pessoas negras e de cor nos mapas populacionais do Maranhão colonial (1798-1821) / At the Core of Africanization: Black and Colored People in Population Maps of Colonial Maranhão, Brazil (1798-1821) / En el núcleo de africanización: pueblo negro y de color en los mapas de población del Maranhão colonial, Brasil (1798-1821)

O estudo analisa o "boom" demográfico das populações escravas de origem africana nas áreas de plantation a partir dos Mapas Estatísticos do Maranhão. Em especial, focalizamos a freguesia do Rosário do Itapecuru utilizando outras fontes documentais - inventários post mortem e registros paroquiais de batismo. Os Mapas de 1798 e 1821 possibilitaram evidenciar o perfil sexual, etário, étnico e a condição jurídica da população, mostrando a importância da população escrava nas áreas de cultivo do algodão e arroz, que chegava a quase 80% dos residentes. Essas populações, por sua vez, guardavam algumas particularidades em relação a outras áreas de plantation do Estado do Brasil, como, por exemplo, a razão de sexo marcada pela quase paridade entre homens e mulheres.

The study analyzes the demographic boom of African slave populations in the plantation areas from the Mapas de População of Maranhão. In particular, we focus on the parish of Rosário do Itapecuru using other sources - post-mortem inventories and parish baptismal records. The maps from 1798 and 1821 made it possible to evidence the gender, age, ethnicity and legal status of the resident population as well as show the importance of slave population in cotton and rice crop areas, reaching almost 80% of residents. These populations, in turn, presented certain peculiarities in relation to other plantation areas in the State of Brazil, such as the sex ratio marked by the almost parity between men and women.

El estudio analiza el boom de las poblaciones esclavas de origen africano en las áreas de plantación a partir de los Mapas Estadísticos de Maranhão. En particular, nos centramos en la parroquia Rosario del Itapecurú utilizando otras fuentes documentales: inventarios post mortem y registros parroquiales de bautismo. Los mapas de 1798 y 1821 posibilitaron evidenciar el perfil sexual, la edad, la condición étnica y jurídica de la población residente y muestran la importancia de la población esclava en las áreas de cultivo de algodón y de arroz, que llega a casi 80% de los residentes. Estas poblaciones mantenían a su vez algunas peculiaridades en relación con otras áreas de plantación del Estado de Brasil, por ejemplo, la proporción de sexos marcada por la casi paridad entre hombres y mujeres.

Bayesian nonparametric areal wombling for small-scale maps with an application to urinary bladder cancer data from Connecticut.

With increasingly abundant spatial data in the form of case counts or rates combined over areal regions (eg, ZIP codes, census tracts, or counties), interest turns to formal identification of difference "boundaries," or barriers on the map, in addition to the estimated statistical map itself. "Boundary" refers to a border that describes vastly disparate outcomes in the adjacent areal units, perhaps caused by latent risk factors. This article focuses on developing a model-based statistical tool, equipped to identify difference boundaries in maps with a small number of areal units, also referred to as small-scale maps. This article proposes a novel and robust nonparametric boundary detection rule based on nonparametric Dirichlet processes, later referred to as Dirichlet process wombling (DPW) rule, by employing Dirichlet process-based mixture models for small-scale maps. Unlike the recently proposed nonparametric boundary detection rules based on false discovery rates, the DPW rule is free of ad hoc parameters, computationally simple, and readily implementable in freely available software for public health practitioners such as JAGS and OpenBUGS and yet provides statistically interpretable boundary detection in small-scale wombling. We offer a detailed simulation study and an application of our proposed approach to a urinary bladder cancer incidence rates dataset between 1990 and 2012 in the 8 counties in Connecticut.

A Map of Clinical Dermatology Research Centers in Spain: Results of the MaIND Study. / Mapa de centros de investigación clínica dermatológica española: resultados del estudio MaIND.

BACKGROUND AND OBJECTIVE: Bibliometric indicators and analyses of clinical research articles can help to quantify the scientific production of hospitals and institutions and identify their main areas of research. The aim of this study was to draw up a bibliometric map of clinical research in dermatology by Spanish hospitals and institutions through an analysis of quantitative, qualitative, and topic-based variables. MATERIAL AND METHOD: Bibliometric study of clinical research articles that met the inclusion criteria and had a definitive publication date between 2005 and 2014 in PubMed or Embase in which the corresponding author's affiliation was a Spanish dermatology department or institution. RESULTS: Barcelona and Madrid were the provinces with the highest number of articles and citations. The centers with the most articles and citations were Hospital Clínic and Instituto Valenciano de Oncología. Those 2 hospitals also produced the highest number of articles on the most common research topic identified: melanoma. Because the articles were selected on the basis of the affiliation of the corresponding author to a Spanish dermatology center, this analysis does not include collaborative studies or clinical research studies led by nondermatology centers. CONCLUSIONS: We have created a bibliometric map of clinical dermatology research in Spain that shows the distribution of scientific production and the main areas of research by province and hospital/institution. This map could be useful for education and research purposes.

Google Maps offers a new way to evaluate claudication.

BACKGROUND: Accurate determination of walking capacity is important for the clinical diagnosis and management plan for patients with peripheral arterial disease. The current "gold standard" of measurement is walking distance on a treadmill. However, treadmill testing is not always reflective of the patient's natural walking conditions, and it may not be fully accessible in every vascular clinic. The objective of this study was to determine whether Google Maps, the readily available GPS-based mapping tool, offers an accurate and accessible method of evaluating walking distances in vascular claudication patients. METHODS: Patients presenting to the outpatient vascular surgery clinic between November 2013 and April 2014 at the Ottawa Hospital with vasculogenic calf, buttock, and thigh claudication symptoms were identified and prospectively enrolled in our study. Onset of claudication symptoms and maximal walking distance (MWD) were evaluated using four tools: history; Walking Impairment Questionnaire (WIQ), a validated claudication survey; Google Maps distance calculator (patients were asked to report their daily walking routes on the Google Maps-based tool runningmap.com, and walking distances were calculated accordingly); and treadmill testing for onset of symptoms and MWD, recorded in a double-blinded fashion. RESULTS: Fifteen patients were recruited for the study. Determination of walking distances using Google Maps proved to be more accurate than by both clinical history and WIQ, correlating highly with the gold standard of treadmill testing for both claudication onset (r = .805; P < .001) and MWD (r = .928; P < .0001). In addition, distances were generally under-reported on history and WIQ. The Google Maps tool was also efficient, with reporting times averaging below 4 minutes. CONCLUSIONS: For vascular claudicants with no other walking limitations, Google Maps is a promising new tool that combines the objective strengths of the treadmill test and incorporates real-world walking environments. It offers an accurate, efficient, inexpensive, and readily accessible way to assess walking distances in patients with peripheral vascular disease.

Snow's case revisited: new tool in geographic profiling of epidemiology

Abstract Geographic Profiling technique is used to find the origin of a series of crimes. The method was recently extended to other fields. One of the best renowned data in epidemiology is that by John Snow during an outburst of cholera in London. We wrote Python scripts to perform the analyses to apply the Geographic Profiling for individuating the starting origin of an infection by using the old Snow's data set. We modified the method by applying a weight to each point of the map where cases of cholera were reported. The weight was proportional to the number of cases in a given location.This modification of the Geographic Profiling method allowed to individuate in the map an area of maximum probability of the infection source, which was a few meters wide and including the historically known source of cholera, that is the "classical" water pump at Broad Street.The method appears to be a useful complement in order to individuate the source of epidemics when available data about the cases of the infections can be summarized on a map.

A conduit between epidemiological research and regional health policy.

OBJECTIVE: To transform data from a research setting into a format that could be used to support strategies encouraging healthy lifestyle choices and service planning within local government. METHODS: Details of the health status and lifestyle behaviours of the Geelong, Victoria, population were generated independently by the Geelong Osteoporosis Study (GOS), a prospective population-based cohort study. Recent GOS follow-up phases provided evidence about patterns of unhealthy diet, physical inactivity, smoking and harmful alcohol use. These factors are well-recognised modifiable risk factors for chronic disease; the dataset was complemented with prevalence estimates for musculoskeletal disease, obesity, diabetes, cardiovascular disease, asthma and cancer. RESULTS: Data were provided to Healthy Together Geelong in aggregate form according to age, sex and suburb. A population statistics company used the data to project health outcomes by suburb for use by local council. This data exchange served as a conduit between epidemiological research and policy development. CONCLUSION AND IMPLICATIONS: Regional policy makers were informed by local evidence, rather than national or state health survey, thereby optimising potential intervention strategies.

Does smoke cross the border? Cigarette tax avoidance in France.

This paper examines the impact on cigarette sales of the successive increases in cigarette prices in France from 2002 to 2004. Since the price differential between France and neighboring countries increased over the period in question, cross-border purchases became more financially attractive for smokers living near borders. Results from difference-in-differences estimates indicate that the decrease in cigarette sales observed in French border departments was around 20 % higher from 2004 to 2007 compared to non-border departments. The loss of fiscal revenue due to cross-border shopping since the tax increase amounts to 2 billion euros over the period 2002-2007. Our findings highlight the need for improved coordination of policies aimed at reducing tobacco consumption across European Union countries.

Travel patterns of cancer surgery patients in a regionalized system.

BACKGROUND: Regionalization of complex surgeries has increased patient travel distances possibly leaving a substantial burden on those at risk for poorer surgical outcomes. To date, little is known about travel patterns of cancer surgery patients in regionalized settings. To inform this issue, we sought to assess travel patterns of those undergoing a major cancer surgery within a regionalized system. MATERIALS AND METHODS: We identified 4733 patients who underwent lung, esophageal, gastric, liver, pancreatic, and colorectal resections from 2002-2014 within a multihospital system in the Mid-Atlantic region of the United States. Patient age, race and/or ethnicity, and insurance status were extracted from electronic health records. We used Geographical Information System capabilities in R software to estimate travel distance and map patient addresses based on cancer surgery type and these characteristics. We used visual inspection, analysis of variance, and interaction analyses to assess the distribution of travel distances between patient populations. RESULTS: A total of 48.2% of patients were non-white, 49.9% were aged >65 y, and 54.9% had private insurance. Increased travel distance was associated with decreasing age and those undergoing pancreatic and esophageal resections. Also, black patients tend to travel shorter distances than other racial and/or ethnic groups. CONCLUSIONS: These maps offer a preliminary understanding into variations of geospatial travel patterns among patients receiving major cancer surgery in a Mid-Atlantic regionalized setting. Future research should focus on the impact of regionalization on timely delivery of surgical care and other quality metrics.
