Introduction Neuropsychiatric symptoms (NPSs) in elderly patients with dementia are frequent in long-term care facilities (LTCFs) and are associated with adverse events. Telemedicine is an emerging way to provide consultation and care to dependent LTCF residents who may not have easy access to specialty services. Several studies have evaluated telemedicine for dementia care but to date, no study has evaluated its impact in the management of NPS in patients with dementia living in LTCF. Methods and analysis The Dementia in long-term care facilities: Telemedicine for the management of neuropsychiatric symptoms (DETECT) study is a 24-month multicentre prospective cluster randomised controlled study with two arms: a control arm (usual care) and an intervention arm (telemedicine consultation) for NPSs management. DETECT enrolled 20 LTCFs. The primary outcome is based on the acceptability of the telemedicine among the LTCF staff which will be assessed in the intervention group by quantitative and qualitative indicators. The rate of unscheduled hospitalisations and/or consultations due to disruptive NPSs, psychotropic drug use and health costs will be described in both groups. Approximately, 200 patients are expected to be recruited. Ethics and dissemination The study protocol was approved and sponsored by the French Ministry of Health. The study received ethical approval from the Toulouse University Hospital Institutional Review Board. We will communicate the final results to the public via conferences and results will also be submitted for publication in international peer-reviewed scientific journals. Trial registration number NCT02472015.

International audience; BACKGROUND: To analyse whether Adverse Childhood Experiences (ACE) are associated with an increased risk of cancer. METHODS: The National child development study (NCDS) is a prospective birth cohort study with data collected over 50 years. The NCDS included all live births during one week in 1958 (n = 18558) in Great Britain. Self-reported cancer incidence was based on 444 participants reporting having had cancer at some point and 5694 reporting never having cancer. ACE was measured using reports of: 1) child in care, 2) physical neglect, 3) child's or family's contact with the prison service, 4) parental separation due to divorce, death or other, 5) family experience of mental illness & 6) family experience of substance abuse. The resulting variable had three categories, no ACEs/ one ACE/ 2 + ACEs and was used to test for a relationship with cancer. Information on socioeconomic characteristics, pregnancy and birth were extracted as potential confounders. Information on adult health behaviours, socioeconomic environment, psychological state and age at first pregnancy were added to the models. Multivariate models were run using multiply-imputed data to account for missing data in the cohort. RESULTS: The odds of having a cancer before 50y among women increased twofold for those who had 2+ ACEs versus those with no ACEs, after adjusting for adult factors and early life confounders (OR: 2.1, 95%CI: 1.42-3.21, p < 0.001). CONCLUSION: These findings suggest that cancer risk may be influenced by exposure to stressful conditions and events early on in life. This is potentially important in furthering our understanding of cancer aetiology, and consequently in redirecting scientific research and developing appropriate prevention policies.

Background In contrast to sessile serrated adenomas and traditional serrated adenomas which are associated with a significant cancer risk, the role of hyperplastic polyps (HP) in colorectal carcinogenesis as well as the molecular mechanisms underlying their development remain controversial and still need to be clarified. Several reports suggest that a subset of HP may represent precursor lesions of some colorectal cancers. However, biomarkers are needed to identify the subset of HP that may have a malignant potential. The hormone precursor, progastrin (PG) has been involved in colon carcinogenesis and is known to activate pro-oncogenic pathways such as the ERK or the STAT3 pathway. We therefore analyzed PG expression and the activation of these signaling factors in HP. Methods We retrospectively analyzed PG expression as well as the phosphorylation of ERK and STAT3 by immunohistochemistry in HP from 48 patients. Results Mean percentages of epithelial cells positive for PG or phospho-ERK were respectively, 31% and 33% in HP and were significantly higher in these lesions compared to normal colon (3%, p = 0.0021 and 7%, p = 0.0008, respectively). We found a significant correlation between PG and phospho-ERK expression in HP with ERK activation significantly stronger in lesions with high progastrin expression (p = 0.015). In contrast, STAT3 was not significantly activated in HP compared to normal colon and we did not observe a significant correlation with PG expression. Conclusions HP overexpressing PG that have the highest activation of the ERK pathway might reflect less latent lesions that might have a malignant potential.
