Training as an Intervention to Decrease Medical Record Abstraction Errors Multicenter Studies.

Studies often rely on medical record abstraction as a major source of data. However, data quality from medical record abstraction has long been questioned. Electronic Health Records (EHRs) potentially add variability to the abstraction process due to the complexity of navigating and locating study data within these systems.

Excess lung cancer occurrence in poultry plants. Occupational risk factors: Findings for oncogenic viruses exposure and other occupational exposures.

Certain viruses naturally infect and cause cancer in chickens and turkeys. Humans are widely exposed. The viruses cause cancer in primates, and transform human cells in vitro, but it is not known if they cause cancer in humans, mainly because of the lack of epidemiologic evidence.

Electronic Nicotine Delivery Systems and Smoking Cessation in Arkansas, 2014.

Objectives: As of October 2015, evidence needed to make a recommendation about the use of electronic nicotine delivery systems (ENDS) for smoking cessation was limited. We used the 2014 Arkansas Behavioral Risk Factor Surveillance System with additional state-specific questions to determine the prevalence of ENDS use, the impact of ENDS use on smoking cessation, and beliefs about ENDS use in Arkansas. Our objectives were to determine if (1) ENDS use was associated with lower odds of quitting smoking, (2) ENDS users believed that ENDS use was not harmful to their health, and (3) ENDS users believed that switching to ENDS reduced their tobacco-related health risks.

Long-Term Nonmalignant Disease Mortality in Subjects Exposed to Transmissible Agents Present in Animals Used for Food.

Objective: To study mortality from nonmalignant diseases in subjects with high exposure to transmissible agents present in animals used for food, and in their raw or inadequately cooked products.

Methods: Mortality was compared in a cohort of meat handlers in slaughtering and processing plants with that of the U.S.

Obesity is associated with visit-to-visit systolic blood pressure variability in the US adults.

Background: Evidence has accumulated showing that blood pressure variability is associated with cardiovascular disease. A substantial increase in the prevalence of obesity has been documented globally. Our objective was to examine the relation of total and central obesity on visit-to-visit blood pressure variability.

In situ remineralisation of eroded enamel lesions by NaF rinses.

Objective: The purpose of this pilot study was to evaluate the remineralisation of eroded enamel by NaF rinses in an intra-oral model.

Methods: Serving as their own control, subjects (N=80) participated in a randomised, four-leg (20 subjects/leg), 28-day, parallel design study. In each leg, each participant wore a customised orthodontic bracket attached to a mandibular molar that contained one tooth block having an initial erosive lesion (0.

In situ remineralization of white-spot enamel lesions by 500 and 1,100 ppm F dentifrices.

The aim of this study was to evaluate the remineralization potential of three silica-containing NaF dentifrice systems in an intraoral model. Subjects (N = 30) in this randomized, three-phase, 28-day, crossover study served as their own control. Each participant wore a customized orthodontic appliance attached to a mandibular molar and contained one tooth block with caries-like lesion.
