Immunogenicity of quadrivalent human papillomavirus vaccine among Alaska Native children aged 9-14 years at 5 years after vaccination.

Background: Persistent human papillomavirus (HPV) infection can cause anogenital and oropharyngeal cancers. Many HPV infections and HPV-associated cancers are vaccine-preventable. Studies suggest long-term persistence of vaccine-induced antibodies.

Long-Term Decrease in Intraocular Pressure in Survivors of Ebola Virus Disease in the Partnership for Research on Vaccines and Infectious Diseases in Liberia (PREVAIL) III Study.

Objective: Survivors of Ebola virus disease (EVD) experience decreased intraocular pressure (IOP) relative to unaffected close contacts during the first year of convalescence. Whether this effect persists over time and its relationship to intraocular pathology are unclear. We sought to determine whether IOP remained lower in survivors of EVD over 4 years of follow-up and to identify associated risk factors.

Characterization of Ebola Virus-Associated Eye Disease.

Importance: Survivors of Ebola virus disease (EVD) may experience ocular sequelae. Comparison with antibody-negative individuals from the local population is required to characterize the disease.

Objective: To assess features of ophthalmic disease specific to EVD.

Adult and paediatric haematology and clinical chemistry laboratory reference limits for Liberia.

Background: As more research is conducted in Liberia, there is a need for laboratory reference limits for common chemistry and haematology values based on a healthy population. Reference limits from the United States may not be applicable.

Objective: The aim of this study was to present laboratory reference ranges from a Liberian population and compare them to United States ranges.

Impact of a prevention bundle on Clostridium difficile infection rates in a hospital in the Southeastern United States.

We sought to assess the impact of a multicomponent prevention program on hospital-acquired Clostridium difficile infections in a hospital in the Southeastern United States. We collected retrospective data of 140 patients from years 2009-2014 and applied the Poisson regression model for analysis. We did not find any significant associations of increased risk of Clostridium difficile infections for the preintervention group.

Pet Ownership and the Risk of Dying from Cardiovascular Disease Among Adults Without Major Chronic Medical Conditions.

Introduction: In a recent statement, the American Heart Association stated "There are scant data on pet ownership and survival in people without established cardiovascular disease (CVD)". This study sought to fill this gap.

Methods: We analyzed nationally representative data of 3964 adults aged ≥50 who were free from major physical illnesses.
