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. FIT diagnostic accuracy for AN was evaluated with Chi-square test at a 20 mg hemoglobin/g of feces cut-off value. Finally, we determined which variables were independently related to AN. Results: An AN was found in 151 (11.5%) patients. The overall accuracy was not statistically different between both cohorts for AN (88.4%, 91.7%; p ¼ 0.051). At the cut-off stablished, differences in FIT sensitivity (31.1%, 40.6%; p ¼ 0.2) or specificity (96.5%, 97.3%; p ¼ 0.1) were not statistically significant. Finally, independent variables such as sex (male) (odds ratio (OR) 2.1, 95% confidence interval (CI) 1.4-3.1), age (50-65, >65 years) (OR 2.1, 95% CI 1.1-4.3; OR 2.7, 95% CI 1.2-6.1), previous colonoscopy (OR 0.4, 95% CI 0.2-0.9) and FIT 20 mg/g feces (OR 17.7, 95% CI 10.8-29.1) were associated with AN diagnosis. Conclusions: FIT accuracy for AN detection is equivalent in average and familial-risk CRC screening cohorts.

The efficacy of continuous positive airway pressure (CPAP) treatment in elderly patients with nonsevere obstructive sleep apnoea (OSA) is controversial. The objective of this study was to assess the effect of CPAP treatment in elderly patients with moderate OSA in terms of clinical, quality-of-life and neurocognitive measures.This was an open-label, randomised, multicentre clinical trial in 145 elderly patients (≥70 years old) with confirmed moderate OSA (apnoea–hypopnoea index 15–29.9 events·h−1) randomised to receive CPAP (n=73) or no CPAP (n=72) for 3 months. The primary end-point was the Epworth Sleepiness Scale (ESS) score, and the secondary end-points included quality of life (Quebec Sleep Questionnaire (QSQ) domain scores), sleep-related symptoms, presence of anxiety/depression, office-based blood pressure measurements and some neurocognitive tests. The analysis was performed according to the intention-to-treat principle.Mean±sd age was 74.9±4.6 years. The CPAP group achieved a greater improvement in the ESS score (adjusted difference of 2.6 (95% CI 3.6–1.6) points; effect size 1) in some sleep-related symptoms and in some dimensions of the QSQ questionnaire (nocturnal symptoms: −0.7 (95% CI −0.3–−1.0) points; p<0.0001 and emotions: −0.4 (95% CI −0.1–−0.7) points; p=0.023). However, CPAP did not demonstrate any effect on either neurocognitive tests (including anxiety and depression) or blood pressure levels. There was a positive correlation between the effect of CPAP and the improvement in ESS scores and quality of life domains.CPAP treatment resulted in a significant improvement in diurnal hypersomnia and some sleep-related symptoms and quality of life domains in elderly patients with moderate OSA.
