The crossdip correction as a tool to improve imaging of crooked line
seismic data: A case study from the post-glacial Burträsk fault,
Sweden
Authors: Beckel Ruth A. , Juhlin Christopher
Published: December 2018

Abstract. Understanding the development of post-glacial faults and their associated seismic activity is crucial for risk assessment in Scandinavia. However, imaging these features and their geological environment is complicated due to special challenges of their hardrock setting, such as weak impedance contrasts, sometimes high noise levels and crooked acquisition lines. A crooked line geometry can cause time shifts that seriously de-focus and deform reflections containing a crossdip component. Advanced processing methods like swath 3D processing and 3D pre-stack migration can, in principle, handle the crooked line geometry, but may fail when the noise level is too high. For these cases, the effects of reflector crossdip can be compensated for by introducing a linear correction term into the standard processing flow. However, existing implementations of the crossdip correction rely on a slant stack approach which can, for some geometries, lead to a duplication of reflections. Here we present a module for the crossdip correction that avoids the reflection duplication problem by shifting the reflections prior to stacking. Based on tests with synthetic data, we developed an iterative processing scheme where a sequence consisting of crossdip correction, velocity analysis and DMO correction is repeated until the stacked image converges. Using our new module to reprocess a reflection seismic profile over the post-glacial Burträsk Fault in Northern Sweden increased the image quality significantly. Strike and dip information extracted from the crossdip analysis helped to interpret a set of southeast dipping reflections as shear zones belonging to the regional scale Burträsk Shear Zone (BSZ), implying that the BSZ itself is not a vertical, but a southeast dipping feature. Our results demonstrate that the crossdip correction is a highly useful alternative to more sophisticated processing methods for noisy datasets. This highlights the often underestimated potential of rather simple, but noise-tolerant methods, in processing hardrock seismic data.
Regional Pliocene Exhumation of the Lesser Himalaya in the Indus
Drainage
Authors: Clift Peter D. , Zhou Peng , Stockli Daniel F. , Blusztajn Jerzy
Published: December 2018

Abstract. New bulk sediment Sr and Nd isotope data, coupled with U-Pb dating of detrital zircon grains from sediment cored by International Ocean Discovery Program in the Arabian Sea, allow reconstruction of erosion in the Indus catchment since ~ 17 Ma. Increasing εNd values from 17 to 9.5 Ma imply relatively more erosion from the Karakoram/Kohistan, likely linked to slip on the Karakoram Fault and compression in the Southern and Eastern Karakoram. After a period of relative stability from 9.5 to 5.7 Ma there is a long-term decrease in εNd values that correlates with increasing relative abundance of > 300 Ma zircon grains that are most common in Himalayan bedrocks, precluding large-scale drainage capture as the cause of decreasing εNd values in the submarine fan. Although the initial increase in Lesser Himalaya-derived 1500–2300 Ma zircons after 8.3 Ma is consistent with earlier records from the foreland basin the much greater rise after 1.9 Ma, has not previously been recognized and suggests that widespread unroofing of the Crystalline Lesser Himalaya and to a lesser extent Nanga Parbat did not occur until after 1.9 Ma. No simple links can be made between erosion and the development of the South Asian Monsoon, implying a largely tectonic control to Lesser Himalayan unroofing.
Diálogo intertextual en la "Penelopeide" de Patrizia Monaco
Authors: Martín Clavijo Milagro
Published: December 2018

«Non mi piace il ruolo che mi ha dato la storia», afirma Penélope, la protagonista de la Penelopeide de Patrizia Monaco, 2010; por eso, decide romper con el silencio secular: no está de acuerdo con que se la presente como modelo de fidelidad conyugal, pero tampoco como una libertina. Su historia es mucho más compleja. Las preguntas que yacen en el fondo y a las que se intenta responder con esta obra son: ¿qué hay de verdad y qué de ficción en la historia que se nos ha transmitido del mito? y ¿cuáles son las fronteras, tan poco marcadas y precisas, entre la experiencia vital y el mundo mitológico? Para contar la versión de Penélope la dramaturga italiana entremezcla lecturas de diversa índole que aquí nos proponemos analizar: la versión de Homero, diferentes versiones posthoméricas clásicas, la perspectiva seguida por Margaret Atwood en Penelopiad y algunos poemas de Cavafis y Safo. De esta manera, Monaco nos presenta a una Penélope diferente, profundamente humana, una mujer que tiene mucho que decir también en el siglo XXI.

Questo articolo illustra un progetto di ricerca, finalizzato alla creazione di proposte didattiche da usare in classe, per sviluppare consapevolezza sulle convenzioni discorsive che regolan il comportamento quotidiano e quindi contribuire allo sviluppo della competenza discorsiva in italiano LS. Nella prima parte si descrivono i criteri utilizzati per l’elaborazione di un corpus, composto da conversazioni faccia a faccia, raccolte in situazioni sia simmetriche che asimmetriche, tra parlanti italiani. Nella seconda si illustrano le scelte metodologiche adottate per l’elaborazione del blog Ma dai!, e si presenta un’unità di lavoro contenuta nello stesso blog. Si tratta di materiale didattico che consente agli studenti di osservare le norme discorsive in uso che regolano la lingua oggetto di studio, attraverso l’analisi di stralci di conversazioni spontanee, realizzate tramite un’accurata analisi dei meccanismi conversazionali. Si conclude che l’utilizzo del quadro applicativo nato in seno all’Analisi della Conversazione possa costituire una valida risorsa, da usare in classe, per esplorare l’input tratto dalla vita reale e sensibilizzare gli apprendenti allo sviluppo della competenza interazionale in italiano LS.
El "Cansonero" del conde de Popoli, ¿un cancionero napolitano «fecho al hispánico modo»?
Authors: Rodríguez Mesa Francisco José
Published: December 2018

Tras la muerte de Alfonso el Magnánimo y con la ascensión al trono partenopeo de Ferrante surge en Nápoles un filón poético en lengua italiana que se ha bautizado tradicionalmente como lírica de koiné y que tiene en el denominado «Cansonero» encargado por Giovanni Cantelmo, sexto conde de Popoli, su máxima expresión. Sin embargo y a pesar de esta primacía, los principales estudios acerca de esta recopilación adolecen de ciertos problemas que vienen determinados por el hecho de que los métodos de análisis a los que se ha sometido el códice parten de presupuestos que se demuestran válidos solo para cancioneros de un solo autor. En este artículo se sugiere la aplicación de los métodos de análisis propios de la poesía cancioneril ibérica –que tiene en la recopilación lírica de varios autores su principal tipología textual– para poner de relieve algunos de los aspectos que la crítica del «Cansonero» ha obviado o incluso negado hasta tiempos muy recientes.
Frasi nominali in un corpus di verbali di interventi chirurgici
Authors: D'Argenio Elisa , Vecchia Cesarina
Published: December 2018

Lo studio si propone di illustrare alcune frasi nominali tratte da un corpus di descrizioni di interventi chirurgici. In tali documenti è ampiamente confermata la preferenza tipica dei testi delle prassi mediche per la predicazione nominale in luogo di quella verbale. Il corpus infatti presenta numerose frasi nominali e, con particolare frequenza, nominalizzazioni formate da un nome d’azione con argomento introdotto da preposizione. Accanto a costruzioni di questo tipo compaiono strutture non prototipiche in cui sono giustapposti un nome d’azione e un nome concreto; in questi stessi contesti ricorre inoltre una struttura in cui si attesta il solo nome concreto. L’analisi mostrerà come determinate caratteristiche testuali delle descrizioni di interventi chirurgici possano contribuire all’emergere di frasi nominali con struttura non prototipica attraverso fenomeni di ellissi grammaticale e contestuale.

In particolare, la verifica e l’esplorazione del dialogo zanzottiano con la scrittura e la Weltanschauung dell’Alighieri si concentrano sull’analisi intertestuale della raccolta poetica Conglomerati (2009), di cui sono sottolineate tanto le isotopie generali di carattere dantesco quanto le puntuali emergenze di memorie testuali mutuate dalla Commedia.
"Memento vivere" o cómo escapar de "Alphaville". Algunas notas sobre Godard y el situacionismo
Authors: Valle Corpas Irene
Published: December 2018

A pesar de los insultos que le dirigieron los miembros de la Internacional Situacionista al cine de Godard, existe un campo teórico común que los une: la crítica al neocapitalismo y la sociedad de consumo. El trabajo de Godard, labrado siempre en las fronteras entre documento y ficción, entre ensayo sociológico e imagen poética, guarda fuertes paralelismos con los textos situacionistas que denunciaban la enorme transformación del espacio, el tiempo y el lenguaje en los años sesenta. El mejor ejemplo para recorrer estas afinidades es, a nuestro juicio, Alphaville, une étrange aventure de Lemmy Caution. Haremos por tanto una lectura de esta película en relación con otros títulos del realizador para detenernos en aquellas cuestiones que la ligan a esa vanguardia y a otras vertientes del pensamiento crítico y que tienen que ver con la censura a la separación y la mercantilización del cuerpo y el tiempo en el mundo moderno y la necesidad de liberar la vida.

Epidemiology of Gunshot-Related Injuries in NYC Emergency Departments from 2004-2014
Authors: Agarwal Mansi , Idaikkadar Nimi , Weiss Don
Published: December 2018

Syndromic surveillance identified temporal and spatial patterns in gunshot related visits that are comparable to findings from the New York Police Department, suggesting that ED syndromic data have potential to be used as an accurate near-real time tracking system of gun-related injuries. Syndromic data may not capture all fatal gun-related violence but do include patients who were dead on arrival to the ED. As gunshot-related injuries are typically emergencies, we do not expect patients to be using other health care facilities for these types of visits. Therefore, ED data can be used to evaluate and improve interventions targeting gun-related injuries. Continued monitoring of gunshot-related visits can be beneficial in identifying local hot spots in gun violence around NYC for an efficient public health response by health professionals, law enforcement, policy makers, and community-based organizations.
An Evaluation of the Biosense 2.0 “Poisoning by Medicines” Syndrome Using Chief-Complaint Data in Utah
Authors: Burke Anne , Jackson David , Nakashima Allyn K.
Published: December 2018

Utilization of the BioSense 2.0 system for syndromic surveillance requires validating syndromes for sensitivity and specificity. The objective of this presentation is to evaluate the BioSense 2.0 poisoning by medicines syndrome by determining chief complaint terms for inclusion and exclusion based upon pre-defined ICD-9 codes and a comparison of binned and unbinned chief complaint data. The results of this study suggest that the inclusion of the chief complaint terms "od," "overmedicated," and "ingested" will increase sensitivity, while the exclusion of terms related to alcohol, carbon monoxide, and food poisoning; swallowing a foreign body; and contact dermatitis will increase specificity.

Overcoming Operational Differences to Attain a National Picture for Novel Threats
Authors: Michael Coletta Michael Coletta , Dey Achintya N. , Miller Matthew , Hicks Peter , Ajani Umed
Published: December 2018

Soon after discovery of a MERS case in Indiana, CDC through its BioSense Syndromic Surveillance (SyS) Program joined with certain public health jurisdictions to improve the national-level MERS surveillance picture. Activities were undertaken to bolster local surveillance efforts, despite jurisdictions use of differing SyS tools. This resulted in the ability to generate periodic reports of aggregated MERS-like surveillance data. Many seem to see this initiative to enhance the national MERS surveillance picture as a model to build upon, and a success that can help improve trust and generate hope for creating a meaningful national SyS picture.

Published: December 2018

Decision support systems for malaria elimination must support rapid response to contain outbreaks. The integrated mobile system in Zanzibar has been recognized as one of the most advanced in the world. The system consists of a simple facility-based case notification system that uses common feature phones, and a mobile application for Android tablet computers. The resulting system enables rapid response to new cases, helps to rapidly diagnose and treat secondary case, and provides high-quality data for identifying hot spots, trends, and transmission patterns. This presentation will review the history, technology, results, lessons-learned, and applicability to other contexts.
Developing a National Database of Radon Test Data in Collaboration with EPA: a Pilot Project to Ascertain Feasibility
Authors: Eggers Carrie
Published: December 2018

Radon exposure is the second leading cause of lung cancer after smoking and the number one cause among non-smokers. EPA estimates that one in fifteen homes nationwide has elevated radon levels. Public outreach efforts promote radon testing and subsequent mitigation when unsafe levels are found, yet due to varying state regulations, data are non-standardized, making targeted public health actions challenging.  An EPA-CDC collaboration will test the feasibility for capturing, analyzing and displaying radon data from state and local health departments by conducting a pilot project to standardize previously non-systemized, uncoordinated data sources into a nationally consistent radon information resource.

Published: December 2018

Prior to the October 1, 2015 transition deadline, all public health jurisdictions should prepare for the impact that the ICD-9/10 transition will have on their syndromic surveillance practice. This change presents challenges involving resources, funding, and time constraints for code translation and syndrome classification. It will also require new statistical methodologies to accommodate changes to coding practices. This session describes the process developed to incorporate practical public health input to translate syndromic surveillance syndromes and sub-syndromes from ICD-9 diagnostic codes to ICD-10 codes. These translations will be a solution that addresses how the challenge of the transition can be used to improve surveillance practice.
Challenges in Surveillance for Chikungunya Virus (CHIKV) Infection
Authors: Lucero-Obusan Cynthia A. , Schirmer Patricia , Oda Gina , Holodniy Mark
Published: December 2018

We describe challenges and lessons learned using biosurveillance methods for identifying Chikungunya (CHIKV) infections. Surveillance was performed using VA ESSENCE, electronic laboratory data and facility reports. As of Aug. 14, 2014, 21 confirmed/probable cases were identified at 10 hospitals. The principal challenges were lack of a specific ICD-9 code for CHIKV, use of non-specific symptom codes at initial and subsequent encounters, lack of CHIKV testing, long turn-around times for results, poor uniformity in test names, and infection control not being notified of  suspected/confirmed CHIKV cases.  Based on our experience, a combination surveillance strategy using multiple data sources is essential for CHIKV detection.
Towards a Framework for Data Quality Properties of Indicators used in Surveillance
Authors: Painter Ian , Carroll Lauren , Buckeridge David , Abernethy Neil
Published: December 2018

The Scalable Data Integration for Disease Surveillance project (SDIDS) is developing tools to integrate and present surveillance data from multiple sources, with an initial focus on malaria. Consideration of data quality is particularly important when integrating data from diverse clinical, population-based, and other sources. We used a hierarchical system to organize data quality properties by capturing metadata elements relevant to provenance and generate a framework with which to assess the quality of the surveillance indicators. The resulting framework enables diverse decision makers to consistently and confidently interpret available surveillance data, indicators, and the analyses based on them.

The course was piloted in 7 African countries, and will be implemented in 47 WHO-AFRO countries.
Potential Efficacy of Pregnancy Status on HIV Laboratory Reports
Authors: Brannon Elliott , Fridge Jessica , Foxhood Joseph
Published: December 2018

This study quantified the opportunities for reducing perinatal HIV transmission if pregnancy status was available on laboratory reports. For mothers whose HIV status was known before pregnancy and who had an HIV test during pregnancy, the highest transmission rate occurred in those without a viral load test (7.0%). This analysis suggests pregnancy status on laboratory reports would be useful for targeting women who have an HIV test during pregnancy but no viral load test. Health Departments should continue to work on the identification of pregnancy status on HIV laboratory reports and should require this information in their laboratory reporting guidelines.

Using a Syndromic Surveillance System to Evaluate the Impact of a Change in Alcohol Law
Authors: Dilley Julia A. , Baer Atar , Duchin Jeff , Maher Julie E.
Published: December 2018

In 2011, Washington State voters passed an initiative which closed state liquor stores and opened private sector liquor sales. We examined trends in alcohol-related emergency department (ED) visits associated with this law change. Data were from the King County syndromic surveillance system. Alcohol-related ED visits were identified using chief complaint search strings and diagnosis codes. We used a linear regression model with a spline at the date of law change and controlled for other factors. Significant increases in alcohol-related ED visits were observed associated with the law change among minors (age <21) and adults ages 40 and older.

Authors: Ising Amy , Barnett Clifton , Falls Dennis , Waller Anna E. , Wallace John , Deyneka Lana
Published: December 2018

NC DETECT emergency department (ED) data were analyzed to assess the impact of applying the BioSense 24-hour rule that combines ED visits into a single visit if the patient ID and facility ID are the same and the earliest recorded times occur within the same 24-hour time frame. 4,822,347 unique ED visits from 2013 NC DETECT data were included in this analysis. Applying the 24-hour rule reduced the overall ED visit count in NC by approximately 1.7%. The percentage of ED visits lost was higher for certain types of visits, e.g. behavioral health, healthcare utilization, GI illness and varied significantly across counties in NC.
Google Flu Trends: Spatial Correlation with Influenza Emergency Department Visits
Authors: Klembczyk Joseph , Jalalpour Mehdi , Levin Scott , Washington Raynard , Pines Jesse M. , Rothman Richard , Dugas Andrea
Published: December 2018

Google Flu Trends (GFT) is an internet search query-based application that has been proven to add value to influenza surveillance and forecasting tools. Previous validation studies have focused on national or regional predictions. While these results have been promising, GFT has yet to be extensively validated at the city level. The AHRQ has provided weekly data for influenza-related emergency room visits across 19 cities. Correlation coefficients with city-level GFT range from .67 to .93 with a median of .84. Characterizing the effectiveness of GFT at the local level is crucial to its integration into new surveillance and prediction tools.

Inconsistency of Timeliness in a Chief Complaint-Based Syndromic Surveillance System During Two Influenza Epidemic Seasons
Authors: Tao Tao , Zhao Qi , Zong Jun , Li Xue , Diwan Vinod , Xu Biao
Published: December 2018

This study estimated the early warning timeliness of a chief complaint-based syndromic surveillance system towards seasonal influenza epidemics. Findings showed that the timliness of ILI data sources changed across two influenza epidemic seasons. ILI reported from different levels of health facilities and patient groups showed distinct timeliness towards influenza epidemics indicated by virus positive rate (VPR) from National Influenza Surveillance Network. The changes of dominant strains, clinical manifestations, population groups affected in different influenza seasons might account for this inconsistency.

Geo-based Social Media Analytics and SMART Dashboard for Tracking Influenza Outbreaks
Authors: Tsou Ming-Hsiang , Peddecord Michael , Johnson Jeffrey , Jung Chin-Te
Published: December 2018

To track outbreaks of influenza (flu), we computed twitter rates from 31 US cities and compare rates to influenza-like-illness (ILI) surveillance rates. Over 2 flu seasons, 2012-14, significant correlations and similar graphic patterns were observed. We demonstrate an interactive dashboard "SMART" that allows practitioners to monitor and visualize daily changes of flu tweets and related news. Compared to regional or national approaches such a GoogleFluTrends, this system allows rapid public opinion analysis and flu outbreak detection at the local level. The SMART dashboard can provide timely and actionable information for local for agencies and practitioners.
Adjustment for Baseline Level of Dengue Cases Due to Increased Testing in Singapore
Authors: Ang Li Wei , Lim Cindy Thiow Koon , Ma Stefan , Tay Joanne , Cutter Jeffery
Published: December 2018

Dengue is endemic in Singapore, and the most recent epidemic occurred in 2013. The mean of weekly number of dengue cases over a five-year period provides an indication of the baseline level. In view of increased laboratory testing for dengue in 2013, an adjustment was made to the computation of the baseline level for 2014. The assumption for our approach in incorporating an adjustment factor was that the proportion of hospitalizations among laboratory-confirmed cases remained constant between 2012 and 2013. This adjustment has helped to provide a more accurate indication of the baseline level of dengue for 2014.
Identifying Congenital Syphilis Cases through a Birth Registry Match
Authors: Brannon Elliott , Fridge Jessica , Hitt Jeffrey
Published: December 2018

A syphilis birth registry match was completed for the first time in Louisiana to identify infants perinatally exposed to syphilis that were missed by routine surveillance activities. The match used a locally-developed, deterministic match and identified 18 potential cases of congenital syphilis. These cases could significantly increase Louisiana congenital syphilis case rate which was the highest in the nation in 2012. The match also identified the need of guidelines for the initiation of congenital syphilis investigations. Other states may wish to conduct a similar birth registry match to ensure complete surveillance for cases of congenital syphilis.
Evaluating Ascertainment of Hepatitis C Cases and Deaths by Electronically Linking Surveillance and Vital Statistics Data in Utah
Authors: Burke Anne , Eason Jeffrey , Jackson David , Nakashima Allyn K.
Published: December 2018

Although chronic hepatitis C virus (HCV) infection results in substantial morbidity and mortality, many cases are undiagnosed and reporting to public health is often incomplete. To determine how well surveillance data documents deaths due to HCV, we linked reported HCV cases to death certificate records. Electronic record linkage found 346 deaths and an additional 254 persons were identified as having chronic HCV as a cause of death that had never been reported to public health. These results suggest that enhanced surveillance is needed to allow for more accurate representation of prevalence and mortality trends amongst the HCV population in Utah.
Standardising Syndromic Classification in Animal Health Data
Authors: Dórea Fernanda C. , Dupuy Céline , Vial Flavie , Revie Crawford , Lindberg Ann
Published: December 2018

Data sharing remains a barrier to joint surveillance and the establishment of contingency plans among countries and institutions. Summary statistics are hard to interpret and compare, and nomenclatures for animal disease classification are seldom used. SSynCAHD (Syndromic Classification in Animal Health Data) proposes to harmonise, through the development on an ontology, syndromic surveillance data use rather than data recording. This will be achieved by standardising classification into syndromes, based on records from different sources of animal health data which are (and will continue to be) recorded using an institution own vocabulary.

Authors: Laryea Dennis O. , Awuah Baffour , Amoako Yaw A. , Mensah Samuel , Awittor Fred K.
Published: December 2018

Cancer-related deaths have been projected to increase in sub-Saharan Africa. Cancer control programmes require good quality data in order to provide information for planning and implementing cancer control and prevention activities. Cancer registration and follow-up of cancer cases to estimate survival are useful tools in cancer control programmes. We followed up 136 cases of breast cancer diagnosed from the year 2006 to 2008. The majority of cases (62.5%) could not be reached either by phone or at the residential address indicated in the folders. We recommend a strengthened system of demographic information collection on cases for effective surveillance.

Cholera Public Health Surveillance System in Cameroon
Authors: Ngwa Moise C. , Liang Song , Mbam Leonard , Arabi Mouhaman , Teboh Andrew , Brekmo Kaousseri , Mevoula Onana , Morris John Glenn
Published: December 2018

Public health surveillance is essential for early detection and rapid response to cholera outbreaks. In 2003, Cameroon adopted the integrated disease surveillance and response (IDSR) strategy. We describe cholera surveillance within IDSR-strategy in Cameroon. Data is captured at health facility, forwarded to health district that compiles and directs data to RDPH in paper format. RDPH sends the data to the national level via internet and from there to the WHO. The surveillance system is passive with no data analysis at districts. Thus the goal of IDSR-strategy of data analysis and rapid response at the district has not been met yet.
Tracking Communicable Disease Electronic Laboratory Data in New York State
Authors: Noonan-Toly Candace M. , Wang Xiaohong , Chang Hwa-Gan
Published: December 2018

Tracking electronic communicable disease laboratory reports through reportable disease case creation is a valuable tool for ensuring complete reporting of communicable diseases. In New York State we follow every lab report from its origin through every action taken to case completion or record dismissal. All of these steps can be traced to determine if appropriate action was taken. In this process we also analyze the timeliness of these procedures.
Public Health and Mass Gathering Events: Assessing Need for Surveillance in Wales, UK
Authors: Parmar Priyanka , Thomas Daniel RH
Published: December 2018

The study investigates the need of surveillance during mass gathering events in Wales, UK. An evidenced based risk assessment tool is designed to identify the risk level of an event by grading risk variables present during the occurrence of event. This tool was observed consistent when compared with the international events. The need for a continuous surveillance is associated to the risk level of the mass gathering event. Enhancing the current surveillance system to establish a collaborated department would require less resources to monitor events and for training in emergency conditions.

Computational Method for Epidemic Detection in Multiple populations
Authors: Shatskikh Ekaterina , Ludkovski Michael
Published: December 2018

We propose an epidemic detection algorithm that uses the information about the state of infection in multiple populations. Our method is based on the combination of the Quickest Detection and Sequential Regression Monte Carlo. As a result, we produce a detection map of the model states, where an epidemic is announced.

Reciprocal Data Sharing: Sending Monthly Summary Reports of Syndromic Data to ED
Authors: Tam Anthony W. , Toprani Amita , Mathes Robert
Published: December 2018

New York City (NYC) emergency departments (EDs) expressed interest in receiving summary reports of the data they send to the NYC Department of Health and Mental Hygiene (DOHMH) syndromic surveillance system. We conducted key informant interviews with eight ED directors to determine variables of interest, along with preferred format and frequency of reporting. A two-page report was developed, summarizing total number of ED visits, top ten chief complaints, average number of visits by day of week and shift, and zip code distribution of visitors, to be sent monthly. The goal is to strengthen the relationship between the syndromic surveillance unit and the hospitals that provide us data by creating an ongoing bidirectional system of communication.
What did Syndromic Surveillance Show During London 2012? Lessons for Mass Gatherings
Authors: Todkill Dan , Hughes Helen , Elliot Alex , Morbey Roger , Edeghere Obaghe , Harcourt Sally , McCloskey Brian , Smith Gillian
Published: December 2018

This paper investigates the impact of the London 2012 Olympic and Paralympic Games on syndromic surveillance systems coordinated by Public Health England. The Games had very little obvious impact on the daily number of ED attendances and general practitioner consultations both nationally, and within London. These results provide valuable lessons learned for future mass gathering events.
Evaluation of REDCap as a Tool for Outbreak Data Management, Illinois, 2013-2014
Authors: Vahora Jennifer , Arwady M. Allison
Published: December 2018

Research Electronic Data Capture (REDCap) is a secure web application for building and managing surveys and databases. The Illinois Department of Public Health (IDPH) evaluated the use of REDCap for outbreak management by conducting a retrospective analysis of four recent outbreaks: a restaurant-associated foodborne illness outbreak; introduction of Middle East Respiratory Syndrome; poison ivy/sumac/oak rash outbreak; and a hospital-based New Delhi metallo-beta-lactamase cluster. IDPH evaluated how REDCap could have impacted each response using six criteria: magnitude; self-reporting of symptoms and exposures; storage and multi-site access to lab reports; reuse of templates; repeated measurements; and ability to perform long-term case follow-up.
Statistical Monitoring of Condemnations from Slaughterhouses
Authors: Vial Flavie , Thommen Sarah , Held Leonhard
Published: December 2018

Whole carcass condemnations (WCC) following meat inspection could be a valuable indirect indicator of national herd health to monitor. We evaluate the performance of the improved Farrington algorithm for the detection of simulated outbreaks in meat inspection data. Disease outbreaks of random sizes (leading to increased WCC at slaughter) were simulated in the time series of the number of cattle slaughtered and condemned in Switzerland between 2007 and 2012. Overall, the improved Farrington algorithm led to low false positive rates but the probability of detection was low for small outbreaks.
Outbreak Prediction: Aggregating Evidence Through Multivariate Surveillance
Authors: Vial Flavie , Wei Wei , Held Leonhard
Published: December 2018

Since there is often different information contained in observations from different data sources, outbreak detection systems should be multivariate by nature. Experience from public health shows that, in reality they often fail to achieve acceptable sensitivity while retaining manageable false alert rates. A valuable alternative to classical "outbreak detection" is "outbreak prediction" based on suitably selected model. We think that such an approach is particularly promising for multivariate surveillance. We propose to use Swiss multivariate surveillance data to develop model-based predictive methods which can be used to inform decisions about animal health.
Leveraging the Laboratory Response Network: A Step Toward Implementing IHR (2005)
Authors: Wolford Tyler , Chadwick Christopher , Mangal Chris
Published: December 2018

The International Health Regulations (2005) outlines eight core capacities that focus on maintaining and strengthening the ability to prevent, detect, respond and report public health threats globally. As of May 2013, 100 of the 195 State Parties that agreed to implement the regulations have failed to meet all of the core capacities. The Laboratory Response Network (LRN), an infrastructure of public health laboratories capable of responding to biological, chemical, radiological, and other emerging public health threats, fulfills five out of eight core capacities and could serve as a model for successful implementation of IHR (2005).
