Background: A total colectomy and a frequent life-long endoscopic surveillance are guaranteed to patients with Familial Adenomatous Polyposis (FAP) to reduce their risk of duodenal and rectal stump cancers. However, after surgery, individuals with FAP suffer from an increased number of diarrheal discharges that force them to dietary restrictions. A non-randomized pilot study was conducted to assess whether a three-month low-inflammatory Mediterranean dietary intervention reduces gastro-intestinal markers of inflammation in FAP individuals. The aim of the present work is to evaluate the participant’s adherence to the proposed dietary recommendations and the change in their number of diarrheal discharges. Methods: 26 FAP individuals aged >18 years, who underwent a total colectomy with ileo-rectal anastomosis and were involved in the surveillance program at the Fondazione IRCCS Istituto Nazionale Tumori of Milan, were included in the present analysis. Results: FAP individuals significantly reduced the Not recommended foods (p-value: 0.002) and increased the consumption of the Recommended ones (p-value: 0.075). The adherence to the proposed dietary recommendations was accompanied by a significant decrease in the number of diarrheal discharges (p-value: 0.008). Conclusions: This study suggests that adhering to a low-inflammatory Mediterranean diet has a potential protective effect on the number of diarrheal discharges in FAP individuals.

Objectives: to investigate the association between the adherence to the 2018 World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) recommendations and the prevalence of parameters of sleep quality and quantity in people with metabolic syndrome (MS)., Design: cross-sectional study., Setting and Participants: 126 people with MS included in a randomized controlled trial of Mediterranean diet and metformin for the primary prevention of age-related chronic diseases (Me.Me.Me. study) wore for one week an actigraph called Actiwatch to assess restful sleep parameters (sleep efficiency - SE, actual sleep time - AST, immobile time - IT) and fragmented sleep parameters (moving time - MT, movement and fragmentation index - MFI, sleep latency - SL). At the baseline visit, each participants completed a 24-hour food frequency diary listing what he/she ate the previous day, and the International Physical Activity Questionnaire. These questionnaires were used to build up a score for adherence to seven relevant 2018 WCRF/AICR recommendations., Main Outcome Measures: the prevalence ratios (PRs) and 95% confidence intervals (CIs) of sleep parameters associated with each recommendation and with the number of met recommendations were calculated using a binomial regression model., Results: the PRs for SE>=85% and IT>=84% increased with the number of met recommendations. Meeting 5-7 recommendations compared to 0-2 was associated with a better SE (PR 3.24 for SE>=85%; p=0.03) and IT (PR 1.68 for IT>=84%; p=0.04). The PRs for MFI>=34.5 and SL>=18 minutes decreased with the number of met recommendations. Meeting 5-7 recommendations compared to 0-2 was associated with a 46% lower prevalence of MFI (p=0.02) and 40% lower prevalence of SL (p=0.04)., Conclusions: the findings of this paper suggest that the prevalence of better sleep quality in people with MS might be associated with closer adherence to 2018 WCRF/AICR recommendations.
