Homocysteine and incident atrial fibrillation: The atherosclerosis risk in communities study and the Multi-Ethnic Study of Atherosclerosis

Heart, Lung and Circulation, Wednesday, March 21, 2018

Although many studies have investigated the association of blood homocysteine with major cardiovascular diseases such as coronary heart disease and stroke, research on its association with atrial fibrillation is scarce.

Perceived access and barriers to care among illicit drug users and hazardous drinkers: findings from the Seek, Test, Treat, and Retain data harmonization initiative (STTR)

BMC Public Health, Tuesday, March 20, 2018

Illicit drug use and hazardous drinking among marginalized populations may be associated with greater barriers to care.

Spatio-temporal coherence of dengue, chikungunya and Zika outbreaks in Merida, Mexico

PLOS Neglected Tropical Diseases, Thursday, March 15, 2018

Response to Zika virus (ZIKV) invasion in Brazil lagged a year from its estimated February 2014 introduction, and was triggered by the occurrence of severe congenital malformations. Dengue (DENV) and chikungunya (CHIKV) invasions tend to show similar response lags. We analyzed geo-coded symptomatic case reports from the city of Merida, Mexico, with the goal of assessing the utility of historical DENV data to infer CHIKV and ZIKV introduction and propagation.

Prognostic significance of large airway dimensions on computed tomography in the general population: The Multi-Ethnic Study of Atherosclerosis (MESA) Lung Study

Annals of the American Thoracic Society, Monday, March 12, 2018

Large airway dimensions on computed tomography (CT) have been associated with lung function, symptoms, and exacerbations in COPD, and symptoms in smokers with preserved spirometry. Their prognostic significance in persons without lung disease remains undefined. The goal of this study was to examine associations between large airway dimensions on CT and respiratory outcomes in a population-based cohort of adults without prevalent lung disease. 

Untargeted metabolomics reveals multiple metabolites influencing smoking-related DNA methylation

Epigenomics, Monday, March 12, 2018

The researchers conducted a joint metabolomic–epigenomic study to identify patterns of epigenetic associations with smoking-related metabolites.

Individual and Neighborhood Stressors, Air Pollution and Cardiovascular Disease

International Journal of Environmental Research and Public Health, Thursday, March 8, 2018

The objective of this study is to evaluate the interaction between psychosocial stressors, at both the individual and neighborhood level, and air pollution on cardiovascular disease.

Increased risk of female HIV-1 acquisition throughout pregnancy and postpartum: A prospective per-coital act analysis among women with HIV-1 infected partners

The Journal of Infectious Diseases, Thursday, March 8, 2018

This study found the HIV-1 acquisition probability per condomless sex act steadily increased through pregnancy and was highest during the postpartum period, suggesting that biological changes during pregnancy and postpartum increase female HIV-1 susceptibility.

Risk of sudden sensorineural hearing loss in adults using phosphodiesterase type 5 inhibitors: Population-based cohort study

Pharmacoepidemiology & Drug Safety, Wednesday, March 7, 2018

The objective of the study was to determine the risk of sudden sensorineural hearing loss associated with use of phosphodiesterase type 5 (PDE5) inhibitors.

Contribution of the in-vehicle microenvironment to individual ambient-source nitrogen dioxide exposure: the Multi-Ethnic Study of Atherosclerosis and Air Pollution

The Journal of Exposure Science & Environmental Epidemiology, Tuesday, March 6, 2018

Exposure estimates that do not account for time in-transit may underestimate exposure to traffic-related air pollution, but exact contributions have not been studied directly. To study this, the researchers conducted a two-week monitoring, including novel in-vehicle sampling, in a subset of the Multi-Ethnic Study of Atherosclerosis and Air Pollution cohort in two cities. 

Genetic mechanisms of immune evasion in colorectal cancer

Cancer Discovery, Tuesday, March 6, 2018

To understand the genetic drivers of immune recognition and evasion in colorectal cancer (CRC), the researchers analyzed 1,211 CRC primary tumor samples, including 179 classified as microsatellite instability-high.
