Muscle Nerve
PUBLISHED: 01-08-2013
Show Abstract
Hide Abstract
Motor unit action potential (MUAP) reference values are usually given per muscle and age group. Our aim was to evaluate the change in MUAP size at different contraction levels using the concentric macro (ConMac) EMG technique.

Hospitalization of the elderly in the United States for nonspecific gastrointestinal diseases: a search for etiological clues.
Am J Public Health
PUBLISHED: 06-08-2011
Show Abstract
Hide Abstract
The frequency of hospitalization among the elderly in the United States caused by gastrointestinal diseases between 1991 and 2004 increased dramatically, especially hospitalization of elderly individuals with nonspecific diagnoses. We analyzed 6 640 304 gastrointestinal disease-associated hospitalization records in this 14-year period by comparing the peak times of nonspecific gastrointestinal diseases with those of specific diseases. We found that most nonspecific gastrointestinal diseases peak concurrently with viral enteritis, suggesting a lack of diagnostic testing for viruses, which may adversely affect the efficiency of prevention, surveillance, and treatment efforts.

Snowbirds and infection--new phenomena in pneumonia and influenza hospitalizations from winter migration of older adults: a spatiotemporal analysis.
BMC Public Health
PUBLISHED: 03-09-2011
Show Abstract
Hide Abstract
Despite advances in surveillance and prevention, pneumonia and influenza (P&I) remain among the leading causes of mortality in the United States. Elderly adults experience the most severe morbidity from influenza-associated diseases, and have the highest rates of seasonal migration within the U.S. compared to other subpopulations. The objective of this study is to assess spatiotemporal patterns in influenza-associated hospitalizations in the elderly, by time, geography, and intensity of P&I. Given the high seasonal migration of individuals to Florida, this state was examined more closely using harmonic regression to assess spatial and temporal patterns of P&I hospitalizations by state of residence.

Visual analytics for epidemiologists: understanding the interactions between age, time, and disease with multi-panel graphs.
PLoS ONE
PUBLISHED: 02-15-2011
Show Abstract
Hide Abstract
Visual analytics, a technique aiding data analysis and decision making, is a novel tool that allows for a better understanding of the context of complex systems. Public health professionals can greatly benefit from this technique since context is integral in disease monitoring and biosurveillance. We propose a graphical tool that can reveal the distribution of an outcome by time and age simultaneously.

Measuring disease burden in the older population using the slope-intercept method for population log-linear estimation (SIMPLE).
Stat Med
PUBLISHED: 02-02-2011
Show Abstract
Hide Abstract
Estimating disease burden in the older population can be problematic, due to a dearth of measurements that take into account population dynamics, small population sizes, and age-related disease distribution issues. Age itself explains a substantial amount of the variability in population disease rates. However, in many common techniques to account for age, such as age standardization and age categorization, age is treated as a nuisance parameter. In this paper, we present a method, the slope-intercept method for population log-linear estimation (SIMPLE), to assess disease burden in the Medicare population of the US. We demonstrate the utility and potential limitations of this straightforward and crude method in assessing age-related morbidity, mortality, and case-fatality on multiple geographic levels. We highlight several examples of when this measure is most applicable using examples abstracted from a comprehensive administrative database of hospitalizations in older adults. Traditional measurements of disease burden are compared with the measurements extracted from this modeling method for comparison purposes. We also present spatial and temporal associations between the two measurements the SIMPLE method produces.

Geographic variations and temporal trends of Salmonella-associated hospitalization in the U.S. elderly, 1991-2004: a time series analysis of the impact of HACCP regulation.
BMC Public Health
PUBLISHED: 12-03-2009
Show Abstract
Hide Abstract
About 1.4 million Salmonella infections, a common food-borne illness, occur in the U.S. annually; the elderly (aged 65 or above) are most susceptible. In 1997, the USDA introduced the Pathogen Reduction and Hazard Analysis and Critical Control Points Systems (PR/HACCP) which demands regular Salmonella testing in various establishments processing meat products, such as broiler chickens. Impact evaluations of PR/HACCP on hospitalizations related to Salmonella are lacking.

Dynamic maps: a visual-analytic methodology for exploring spatio-temporal disease patterns.
Environ Health
PUBLISHED: 07-27-2009
Show Abstract
Hide Abstract
Epidemiologic studies are often confounded by the human and environmental interactions that are complex and dynamic spatio-temporal processes. Hence, it is difficult to discover nuances in the data and generate pertinent hypotheses. Dynamic mapping, a method to simultaneously visualize temporal and spatial information, was introduced to elucidate such complexities. A conceptual framework for dynamic mapping regarding principles and implementation methods was proposed.

Healthy-lifestyle behaviors associated with overweight and obesity in US rural children.
BMC Pediatr
Show Abstract
Hide Abstract
There are disproportionately higher rates of overweight and obesity in poor rural communities but studies exploring childrens health-related behaviors that may assist in designing effective interventions are limited. We examined the association between overweight and obesity prevalence of 401 ethnically/racially diverse, rural school-aged children and healthy-lifestyle behaviors: improving diet quality, obtaining adequate sleep, limiting screen-time viewing, and consulting a physician about a childs weight.

Baseline Socio-demographic Characteristics and Self-Reported Diet and Physical Activity Shifts Among Recent Immigrants Participating in the Randomized Controlled Lifestyle Intervention: "Live Well"
J Immigr Minor Health
Show Abstract
Hide Abstract
The goal of this paper is to describe the baseline characteristics of Live Well (intervention to prevent weight gain in recent immigrant mother-child dyads from Brazil, Haiti, and Latin America) participants, and to explore self-reported changes in diet and physical activity post-immigration. Baseline data from 383 mothers were used for this study. Dyads attended a measurement day where they completed self-administered surveys collecting information about socio-demographics, diet, physical activity, other psychosocial variables, and height and weight. Haitian mothers socio-demographic profile differed significantly from that of Brazilians and Latinas: they have been in the US for a shorter period of time, have higher rates of unemployment, are less likely to be married, more likely to have ?3 children, more likely to be obese, and have immigrated for family or other reasons. In multivariate models, self-reported changes in diet and physical activity since migrating to the US were significantly associated with BMI with non-linear relationships identified. Future research is needed to understand how diet and physical activity change while acculturating to the US and explore the adoption of both healthy and unhealthy dietary changes.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
