Accuracy of Cone-Beam Computed Tomography Software in Predicting the Size of Impacted Canine: A Preliminary Study.

Objective: To compare and analyze the precision, accuracy, and reliability of commonly used cone-beam computed tomography (CBCT) software in predicting the mesiodistal diameter of impacted canines.

Methods: This study was conducted on 11 patients (six males and five females, mean age: 17.5±5.

Showcasing Environmental Health and Safety Activities During the Coronavirus Disease 2019 Pandemic.

Introduction: Emergency preparedness is not a novel topic. What has been novel is the fast pace at which organizations, including academic institutions, have had to adapt to infectious disease outbreaks since 2000.

Objective: The goal of this article is to highlight the various environmental health and safety (EHS) team activities during the coronavirus disease 2019 (COVID-19) pandemic to ensure that on-site personnel was safe, the research could be conducted, and critical business operations such as academics, laboratory animal care, environmental compliance, and routine healthcare functions could continue during the pandemic.

Serosurvey on healthcare personnel caring for patients with Ebola virus disease and Lassa virus in the United States.

Objective: Healthcare personnel (HCP) were recruited to provide serum samples, which were tested for antibodies against Ebola or Lassa virus to evaluate for asymptomatic seroconversion.

Setting: From 2014 to 2016, 4 patients with Ebola virus disease (EVD) and 1 patient with Lassa fever (LF) were treated in the Serious Communicable Diseases Unit (SCDU) at Emory University Hospital. Strict infection control and clinical biosafety practices were implemented to prevent nosocomial transmission of EVD or LF to HCP.

NIH Guidelines April 2019.
