A Cross-Sectional Survey of the Zika Virus and its Prevention: The Knowledge, Thoughts, and Beliefs of a Community of Residents in Caguas, Puerto Rico.

Objective: The objective of this study was to explore the knowledge, thoughts, and beliefs regarding the Zika virus and its prevention in a community of residents in the municipality of Caguas, Puerto Rico, and elicit their concerns and perceptions of risk.

Methods: A quantitative, non experimental, descriptive, cross-sectional correlational study was conducted in a community in Caguas, Puerto Rico. A structured questionnaire was administered to a sample of 158 residents, aged 21 and older, who participated voluntarily.

Diagnostic accuracy of fecal immunochemical test in average- and familial-risk colorectal cancer screening.

Background: There is little information about the fecal immunochemical test (FIT) in familial-risk colorectal cancer (CRC) screening.

Objectives: The objective of this article is to investigate whether FIT diagnostic accuracy for advanced neoplasia (AN) differs between average and familial-risk (first-degree relative) patients.

Methods: A total of 1317 consecutive participants (595 familial) who collected one stool sample before performing a colonoscopy as a CRC screening test were included.

Diagnostic performance of fecal immunochemical test and sigmoidoscopy for advanced right-sided colorectal neoplasms.

Background: Colorectal cancer screening effect on right-sided colorectal neoplasia is limited. We compared fecal immunochemical test and simulated sigmoidoscopy diagnostic accuracy for advanced right-sided neoplasia detection.

Methods: We analyzed 1,292 individuals with complete screening colonoscopy with a fecal immunochemical test determination before colonoscopy.

Characteristics of adenomas detected by fecal immunochemical test in colorectal cancer screening.

Background: Fecal immunochemical test (FIT) diagnostic accuracy for colorectal adenoma detection in colorectal cancer screening is limited.

Methods: We analyzed 474 asymptomatic subjects with adenomas detected on colonoscopy in two blinded diagnostic tests studies designed to assess FIT diagnostic accuracy. We determined the characteristics of adenomas (number, size, histology, morphology, and location) and the risk of metachronous lesions (according to European guidelines).

Fecal immunochemical test accuracy in average-risk colorectal cancer screening.

Aim: To assess the fecal immunochemical test (FIT) accuracy for colorectal cancer (CRC) and advanced neoplasia (AN) detection in CRC screening.

Methods: We performed a multicentric, prospective, double blind study of diagnostic tests on asymptomatic average-risk individuals submitted to screening colonoscopy. Two stool samples were collected and the fecal hemoglobin concentration was determined in the first sample (FIT1) and the highest level of both samples (FITmax) using the OC-sensor™.

Fecal immunochemical test accuracy in familial risk colorectal cancer screening.

There is little information on fecal immunochemical test (FIT) in familial risk colorectal cancer (CRC) screening. Our study assesses FIT accuracy, number needed to scope (NNS) and cost to detect a CRC and an advanced neoplasia (AN) in this setting. We performed a multicentric, prospective, double-blind study of diagnostic tests on individuals with first-degree relatives (FDRs) with CRC submitted to screening colonoscopy.
