The Reliability of Tweets as a Supplementary Method of Seasonal Influenza Surveillance.
J. Med. Internet Res.
PUBLISHED: 05-13-2014
Show Abstract
Hide Abstract
Existing influenza surveillance in the United States is focused on the collection of data from sentinel physicians and hospitals; however, the compilation and distribution of reports are usually delayed by up to 2 weeks. With the popularity of social media growing, the Internet is a source for syndromic surveillance due to the availability of large amounts of data. In this study, tweets, or posts of 140 characters or less, from the website Twitter were collected and analyzed for their potential as surveillance for seasonal influenza.

Hide Abstract
Periodontitis is a progressive disease of the periodontium with a complex, polymicrobial etiology. Recent Next-Generation Sequencing (NGS) studies of the microbial diversity associated with periodontitis have revealed strong, community-level differences in bacterial assemblages associated with healthy or diseased periodontal sites. In this study, we used NGS approaches to characterize changes in periodontal pocket bacterial diversity after standard periodontal treatment. Despite consistent changes in the abundance of certain taxa in individuals whose condition improved with treatment, post-treatment samples retained the highest similarity to pre-treatment samples from the same individual. Deeper phylogenetic analysis of periodontal pathogen-containing genera Prevotella and Fusobacterium found both unexpected diversity and differential treatment response among species. Our results highlight how understanding interpersonal variability among microbiomes is necessary for determining how polymicrobial diseases respond to treatment and disturbance.

Hide Abstract
Surveillance plays a vital role in disease detection, but traditional methods of collecting patient data, reporting to health officials, and compiling reports are costly and time consuming. In recent years, syndromic surveillance tools have expanded and researchers are able to exploit the vast amount of data available in real time on the Internet at minimal cost. Many data sources for infoveillance exist, but this study focuses on status updates (tweets) from the Twitter microblogging website.

Associations between nocturnal blood pressure dipping and the metabolic syndrome in high- vs. low-acculturated Mexican American women.
Am. J. Hypertens.

Show Abstract
Hide Abstract
Less nocturnal blood pressure (BP) dipping has been associated with greater odds for the metabolic syndrome (MetS), a constellation of risk factors associated with cardiovascular disease (CVD). Little work has examined this association in Hispanics, who have elevated rates of MetS, or investigated differences in this relationship by level of acculturation. The purpose of this study was to examine the association between BP dipping and MetS in Hispanic women and to determine if this association is moderated by acculturation status.

Show Abstract
Hide Abstract
This study aimed to identify the prevalence and determinants of soft tissue infections and self-treatment among injection drug users (IDUs) in California. The study interviewed 864 IDUs in California using computer-assisted personal interview (CAPI) from 2003 to 2005. Multiple logistic regression analyses were performed to examine adjusted associations for recent abscess and abscess self-treatment. In these analyses, Latinos had higher odds than African Americans to self-treat, while IDUs reporting a usual place of health care had lower odds of self-treatment. Findings suggest an expansion of wound care facilities to mitigate the self-treatment of abscesses, with special consideration to Latinos.

Hide Abstract
Hookah use is gaining popularity nationwide. We determined the correlates and trends for hookah use from the California Tobacco Survey. Between 2005 and 2008 hookah use increased more than 40%, and in 2008, 24.5% of young men reported ever using a hookah. Hookah use was more common among the young (18-24 years), the educated, the non-Hispanic Whites, and the cigarette smokers. Hookah use is increasing in California, especially among young adults, and in 2008 reached the highest prevalence ever reported for both genders.

Hide Abstract
The characteristic facial features of the more severe end of Fetal Alcohol Spectrum Disorders (FASD) include smooth philtrum, thin vermillion of the upper lip, and short palpebral fissures. A systematic evaluation of a comprehensive list of minor structural defects in association with varying patterns of prenatal exposure to alcohol has not been performed. We examined the patterns and timing of prenatal alcohol exposure to minor structural malformations occurring in at least 5% of the sample. Patterns of drinking were evaluated by drinks per day, number of binge episodes, and maximum number of drinks. Timing of exposure was evaluated 0-6 weeks post-conception, 6-12 weeks post-conception, first trimester, second trimester, and third trimester. Naevus flammeus neonatorum is significantly associated with various patterns of drinking during the second half of the first trimester (RR 1.14, 95% CI 1.04, 1.24 for average number of drinks per day; RR 1.04, 95% CI 1.02, 1.07 for number of binge episodes; RR 1.08, 95% CI 1.01, 1.15 for maximum number of drinks in one episode) and similar for number of binge episodes in all categories of timing of exposure and in the second trimester for average number of drinks per day. Other minor malformations occurring in at least 5% of the sample were not found to be significantly associated with prenatal alcohol exposure. Expected minor malformations were not found to be significantly associated with prenatal alcohol exposure. Naevus flammeus neonatorum appears to be part of the spectrum of features associated with prenatal alcohol exposure.

Hide Abstract
Limited research exists on the relationship between physical injury and PTSD within military populations. The present study assessed postinjury rates of PTSD and other psychological correlates among battle and non-battle injuries. A total of 1,968 men (831 battle injuries and 1,137 nonbattle injuries) injured between September 2004 and February 2005 during Operation Iraqi Freedom (OIF) composed the study sample. Patients were followed through November 2006 for mental health diagnosis (ICD-9 290-319). Compared with nonbattle injuries, those with battle injuries had a greater risk of PTSD and other mental health diagnosis, and there was a positive association with injury severity. Self-reported mental health symptoms were significantly higher for both minor and moderate-severe battle injury in comparison to nonbattle injury and previous population estimates from an earlier OIF period. More research is needed to further define this relationship by examining potential mechanisms and addressing the possible contributing effect of combat exposure.

Comparison of overall obesity and body fat distribution in predicting risk of mortality.
Obesity (Silver Spring)
PUBLISHED: 02-05-2009
Show Abstract
Hide Abstract
Results of studies comparing overall obesity and abdominal adiposity or body fat distribution with risk of mortality have varied considerably. We compared the relative importance and joint association of overall obesity and body fat distribution in predicting risk of mortality. Participants included 5,799 men and 6,429 women aged 30-102 years enrolled in the third National Health and Nutrition Examination Survey who completed a baseline health examination during 1988-1994. During a 12-year follow-up (102,172 person-years), 1,188 men and 925 women died. In multivariable-adjusted analyses, waist-to-thigh ratio (WTR) in both sexes (Ptrend<0.01 for both) and waist-to-hip ratio (WHR) in women (Ptrend 0.001) were positively associated with mortality in middle-aged adults (30-64 years), while BMI and waist circumference (WC) exhibited U- or J-shaped associations. Risk of mortality increased with a higher WHR and WTR among normal weight (BMI 18.5-24.9 kg/m2) and obese (BMI>or=30.0 kg/m2) adults. In older adults (65-102 years), a higher BMI in both sexes (Ptrend<0.05) and WC in men (Ptrend 0.001) were associated with increased survival, while remaining measures of body fat distribution exhibited either no association or an inverse relation with mortality. In conclusion, ratio measures of body fat distribution are strongly and positively associated with mortality and offer additional prognostic information beyond BMI and WC in middle-aged adults. A higher BMI in both sexes and WC in men were associated with increased survival in older adults, while a higher WHR or WTR either decreased or did not influence risk of death.

The role of social support and acculturative stress in health-related quality of life among day laborers in Northern San Diego.
J Immigr Minor Health
Show Abstract
Hide Abstract
There is evidence to suggest that Latino day laborers experience higher levels of acculturative stress than Latinos in employment sectors in the US. Given the stress-buffering role that social support plays in minimizing the negative physical and mental health outcomes of stress, this study examined this relationship in a sample of 70 Latino Day laborers in the northern San Diego area(100% male, mean age = 27.7, SD = 9.1). Results from multivariate regression analyses showed that there was a significant interaction effect between social support and acculturative stress (P = 0.025) on physical health, indicating that higher levels of social support buffered the negative effects of acculturative stress on physical health.Acculturative stress and social support were not associated with mental health status. Overall, these findings suggest that fostering social support may be an essential strategy for promoting health among Latino male day laborers.

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.
