Cross Disciplinary Consultancy to Bridge Public Health Technical Needs and Analytic Developers: Negation Detection Use Case.

This paper describes a continuing initiative of the International Society for Disease Surveillance designed to bring together public health practitioners and analytics solution developers from both academia and industry. Funded by the Defense Threat Reduction Agency, a series of consultancies have been conducted on a range of topics of pressing concern to public health (e.g.

Comparison of crowd-sourced, electronic health records based, and traditional health-care based influenza-tracking systems at multiple spatial resolutions in the United States of America.

Background: Influenza causes an estimated 3000 to 50,000 deaths per year in the United States of America (US). Timely and representative data can help local, state, and national public health officials monitor and respond to outbreaks of seasonal influenza. Data from cloud-based electronic health records (EHR) and crowd-sourced influenza surveillance systems have the potential to provide complementary, near real-time estimates of influenza activity.

Surgery and magnetic resonance imaging increase the risk of hypothermia in infants.

Aim: Maintaining normothermia is a tenet of neonatal care. However, neonatal thermal care guidelines applicable to intra-hospital transport beyond the neonatal intensive care unit (NICU) and during surgery or magnetic resonance imaging (MRI) are lacking. The aim of this study is to determine the proportion of infants normothermic (36.

Accurate Influenza Monitoring and Forecasting Using Novel Internet Data Streams: A Case Study in the Boston Metropolis.

Background: Influenza outbreaks pose major challenges to public health around the world, leading to thousands of deaths a year in the United States alone. Accurate systems that track influenza activity at the city level are necessary to provide actionable information that can be used for clinical, hospital, and community outbreak preparation.

Objective: Although Internet-based real-time data sources such as Google searches and tweets have been successfully used to produce influenza activity estimates ahead of traditional health care-based systems at national and state levels, influenza tracking and forecasting at finer spatial resolutions, such as the city level, remain an open question.

Cognition and behaviour in children with congenital abdominal wall defects.

Aim: To characterise neurodevelopment at age two years and cognition and behaviour at age five years in children born with abdominal wall defects (gastroschisis or exomphalos).

Study Design: Participants were treated as neonates for gastroschisis or exomphalos and invited for routine clinical follow-up at ages two and five years. Thirty-nine two year-olds and 20 five year-olds with gastroschisis and 20 two year-olds and 10 five year-olds with exomphalos returned for age-appropriate assessments of development (two years) and intellectual functioning (IQ), executive function, and behavioural problems.

Cross-Disciplinary Consultancy to Enhance Predictions of Asthma Exacerbation Risk in Boston.

This paper continues an initiative conducted by the International Society for Disease Surveillance with funding from the Defense Threat Reduction Agency to connect near-term analytical needs of public health practice with technical expertise from the global research community. The goal is to enhance investigation capabilities of day-to-day population health monitors. A prior paper described the formation of consultancies for requirements analysis and dialogue regarding costs and benefits of sustainable analytic tools.

Perioperative risk factors for impaired neurodevelopment after cardiac surgery in early infancy.

Objective: Historical cohort studies have reported adverse neurodevelopment following cardiac surgery during early infancy. Advances in surgical techniques and perioperative care have coincided with updating of neurodevelopmental assessment tools. We aimed to determine perioperative risk factors for impaired neurodevelopment at 2 years following surgery for congenital heart disease (CHD) in early infancy.

Cross-Disciplinary Consultancy to Bridge Public Health Technical Needs and Analytic Developers: Asyndromic Surveillance Use Case.

Introduction: We document a funded effort to bridge the gap between constrained scientific challenges of public health surveillance and methodologies from academia and industry. Component tasks are the collection of epidemiologists' use case problems, multidisciplinary consultancies to refine them, and dissemination of problem requirements and shareable datasets. We describe an initial use case and consultancy as a concrete example and challenge to developers.

Relationship between Social-Emotional and Neurodevelopment of 2-Year-Old Children with Congenital Heart Disease.

Objective: The purpose of this study was to describe social-emotional outcomes and the relationship with neurodevelopmental outcomes in a cohort of 2-year-old children who underwent surgery for congenital heart disease (CHD) in infancy, and explore the relationship between the outcomes and parental and surgical factors.

Design: A two-center prospective cross-sectional cohort study.

Patients: A cohort of 105 2-year-olds who underwent surgery in infancy for severe CHD MEASURES: Social-emotional and neurodevelopment was evaluated with the Infant and Toddler Social and Emotional Assessment tool (ITSEA), and the Bayley Scales of Infant Toddler Development, Third Edition.

Laboratory-acquired vaccinia virus infection in a recently immunized person--Massachusetts, 2013.

On November 26, 2013, the CDC poxvirus laboratory was notified by the Boston Public Health Commission (BPHC) of an inadvertent inoculation of a recently vaccinated (ACAM2000 smallpox vaccine) laboratory worker with wild type vaccinia virus (VACV) Western Reserve. A joint investigation by CDC and BPHC confirmed orthopoxvirus infection in the worker, who had reported a needle stick in his thumb while inoculating a mouse with VACV. He experienced a non-tender, red rash on his arm, diagnosed at a local emergency department as cellulitis.

Subdural hemorrhage and hypoxia in infants with congenital heart disease.

Background And Objectives: It has been suggested that there is a causal relationship between hypoxia and subdural hemorrhage (SDH) in infancy. The purpose of this study was to review the incidence of SDH in infants with congenital heart disease and explore the relationship between SDH and hypoxia.

Methods: Review of data collected for a prospective longitudinal cohort study of infants undergoing surgery for congenital heart disease in New Zealand and Australia.

Usefulness of routine head ultrasound scans before surgery for congenital heart disease.

Objective: The purpose of this study was to assess the utility of preoperative head ultrasound scan (HUS) in a cohort of newborns also undergoing preoperative MRI as part of a prospective research study of brain injury in infants having surgery for congenital heart disease (CHD).

Methods: A total of 167 infants diagnosed with CHD were included in this 3-center study. None of the patients had clinical signs or symptoms of preoperative brain injury, and all patients received both HUS and brain MRI before undergoing surgical intervention.

New white matter brain injury after infant heart surgery is associated with diagnostic group and the use of circulatory arrest.

Background: Abnormalities on magnetic resonance imaging scans are common both before and after surgery for congenital heart disease in early infancy. The aim of this study was to prospectively investigate the nature, timing, and consequences of brain injury on magnetic resonance imaging in a cohort of young infants undergoing surgery for congenital heart disease both with and without cardiopulmonary bypass.

Methods And Results: A total of 153 infants undergoing surgery for congenital heart disease at <8 weeks of age underwent serial magnetic resonance imaging scans before and after surgery and at 3 months of age, as well as neurodevelopmental assessment at 2 years of age.

Perioperative amplitude-integrated EEG and neurodevelopment in infants with congenital heart disease.

Purpose: Perioperative brain injury is common in young infants undergoing cardiac surgery. We aimed to determine the relationship between perioperative electrical seizures, the background pattern of amplitude-integrated electroencephalography (aEEG) and 2-year neurodevelopmental outcome in young infants undergoing surgery for congenital heart disease.

Methods: A total of 150 newborn infants undergoing cardiac surgery underwent aEEG monitoring prior to and during surgery, and for 72 h postoperatively.

Self-reported fever and measured temperature in emergency department records used for syndromic surveillance.

Many public health agencies monitor population health using syndromic surveillance, generally employing information from emergency department (ED) visit records. When combined with other information, objective evidence of fever may enhance the accuracy with which surveillance systems detect syndromes of interest, such as influenza-like illness. This study found that patient chief complaint of self-reported fever was more readily available in ED records than measured temperature and that the majority of patients with an elevated temperature recorded also self-reported fever.

Amplitude-integrated electroencephalography and brain injury in infants undergoing Norwood-type operations.

Background: Perioperative brain injury is common in infants undergoing cardiac surgery. Amplitude-integrated electroencephalography (aEEG) provides real-time neurologic monitoring and can identify seizures and abnormalities of background cerebral activity. We aimed to determine the incidence of perioperative electrical seizures, and to establish the background pattern of aEEG, in neonates undergoing Norwood-type palliations for complex congenital heart disease in relation to outcome at 2 years.

Developing syndrome definitions based on consensus and current use.

Objective: Standardized surveillance syndromes do not exist but would facilitate sharing data among surveillance systems and comparing the accuracy of existing systems. The objective of this study was to create reference syndrome definitions from a consensus of investigators who currently have or are building syndromic surveillance systems.

Design: Clinical condition-syndrome pairs were catalogued for 10 surveillance systems across the United States and the representatives of these systems were brought together for a workshop to discuss consensus syndrome definitions.

A systematic review of motor and cognitive outcomes after early surgery for congenital heart disease.

Context: Brain injury is the most common long-term complication of congenital heart disease requiring surgery during infancy. It is clear that the youngest patients undergoing cardiac surgery, primarily neonates and young infants, are at the greatest risk for brain injury. Developmental anomalies sustained early in life have lifelong repercussions.

Pre-operative brain injury in newborn infants with transposition of the great arteries occurs at rates similar to other complex congenital heart disease and is not related to balloon atrial septostomy.

Objectives: The goal of this study was to determine the prevalence and pattern of pre-operative brain injury in infants with transposition of the great arteries (TGA) compared with other complex congenital heart disease (CHD) and to define the risk of balloon atrial septostomy (BAS) for the development of brain injury.

Background: It has recently been suggested that infants with TGA are at increased risk of pre-operative brain injury, in particular, stroke, and that this is strongly associated with having a BAS.

Methods: Sixty-four newborn infants with TGA (n = 44), hypoplastic left heart syndrome (n = 13), or pulmonary atresia (n = 7) had magnetic resonance imaging (MRI) scans performed before surgery.

Risk of progression to active tuberculosis among foreign-born persons with latent tuberculosis.

Background: Increased risk for tuberculosis (TB) disease has been identified in foreign-born persons in the United States, particularly during the first 5 years after their arrival in the United States. This could be explained by undetected TB disease at entry, increased prevalence of latent TB infection (LTBI), increased progression from LTBI to TB, or a combination of these factors.

Methods: We performed a cluster analysis of TB cases in Boston and a case-control study of risk factors for TB with an unclustered isolate among Boston residents with LTBI to determine whether such persons have an increased risk for reactivation of disease.

Direct cost associated with the development and implementation of a local syndromic surveillance system.

Objective: Enhancing public health surveillance to include electronic syndromic surveillance systems has received increased attention in recent years. Although cost continually serves as a critical factor in public health decision making, few studies have evaluated direct costs associated with syndromic surveillance systems. In this study, we calculated the direct costs associated with developing and implementing a syndromic surveillance system in Boston, Massachusetts, from the perspective of local, state, and federal governments.

Local collaborations: development and implementation of Boston's bioterrorism surveillance system.

The Boston Public Health Commission developed and implemented an active surveillance system for bioterrorism and other infectious disease emergencies. A bioterrorism Surveillance Task Force was formed with representatives from local emergency medicine, infection control, infectious diseases, public health, and emergency medical services. These local agencies worked together to develop a reliable, easy to use electronic surveillance system.
