RESUMO
Nowadays, prevention, control and treatment of cervical cancer are a worldwide public health priority. Primary objective of this study was to evaluate the level of awareness of female Syrian refugees who have recently settled in Greece regarding the warning signs and the risk factors of cervical cancer. This is a descriptive, cross-sectional study that was conducted in two facilities of the Hellenic Red Cross. The Cervical Cancer Awareness Measure questionnaire was addressed to 176 female Syrian refugees, aged between 18 and 50. Syrian women presented low awareness both for risk factors and warning signs. The most frequently identified warning signs were vaginal bleeding after menopause (44.3%), vaginal bleeding between menstruation (34.1%) and unexplained weight loss (32.4%). Regarding the risk factors' recognition rates, 74.5% considered the existence of many sexual partners as a risk factor and 61.3% the existence of a sexual partner with many previous sexual partners. Older age, a higher level of education and confidence that any potential symptom would be identified were associated with increased awareness. Our findings confirm former published reports that indicate poor awareness regarding cervical cancer among refugee populations. Full compliance with the guidelines of the World Health Organization for a national cervical cancer screening programme is highly advised in Greece and should address the needs of both native and refugee populations. This research is the first one that underlines the need for raising awareness of cervical cancer among female Syrian refugees in Greece by developing health promotion strategies adjusted to their unique cultural needs.

Infiltration of neutrophils into colonic mucosa has been associated with the severity of ulcerative colitis (UC). We investigated the effect of disease microenvironment on the release of neutrophil extracellular traps (NETs) as well as the involved mechanisms in NETosis and whether certain NET proteins are correlated with disease phenotype. Peripheral blood neutrophils, sera, and colonic tissue were collected from treatment-naive and mesalazine-treated patients with active UC, treatment-naive patients with active Crohn's disease, patients suffering from infectious colitis, or healthy individuals (controls). Analysis of colonic biopsy specimens and peripheral blood neutrophils for the presence of NET-related markers using immunofluorescence confocal microscopy, ELISA, immunoblotting, flow cytometry, and quantitative PCR were performed. In vitro cell and tissue culture systems were further deployed. The local inflammatory response in colon in UC, but not Crohn's disease, is characterized by the presence of NETs carrying bioactive IL-1ß and thrombogenic tissue factor. The inflammatory environment of UC is able to induce neutrophil activation, IL-1ß expression, and NET release, as shown both ex vivo and in vitro. REDD1 expression, as a mediator linking inflammation, autophagy, and NET release, was also specifically associated with the inflammatory response of UC. We show that neutrophil expression of REDD1 in colon tissue and the presence of IL-1ß in neutrophils/NETs provide candidate biomarkers for the differential diagnosis of inflammatory colitis and possible targets for the treatment of UC, suggesting that UC shares common features with autoinflammatory disorders.

BACKGROUND: Familial Mediterranean fever (FMF) is an IL-1ß-dependent autoinflammatory disease caused by mutations of Mediterranean fever (MEFV) encoding pyrin and characterized by inflammatory attacks induced by physical or psychological stress. OBJECTIVE: We investigated the underlying mechanism that links stress-induced inflammatory attacks with neutrophil activation and release of IL-1ß-bearing neutrophil extracellular traps (NETs) in patients with FMF. METHODS: RNA sequencing was performed in peripheral neutrophils from 3 patients with FMF isolated both during attacks and remission, 8 patients in remission, and 8 healthy subjects. NET formation and proteins were analyzed by using confocal immunofluorescence microscopy, immunoblotting, myeloperoxidase-DNA complex ELISA, and flow cytometry. Samples from patients with Still's disease and bacterial infections were used also. RESULTS: The stress-related protein regulated in development and DNA damage responses 1 (REDD1) is significantly overexpressed during FMF attacks. Neutrophils from patients with FMF during remission are resistant to autophagy-mediated NET release, which can be overcome through REDD1 induction. Stress-related mediators (eg, epinephrine) decrease this threshold, leading to autophagy-driven NET release, whereas the synchronous inflammatory environment of FMF attack leads to intracellular production of IL-1ß and its release through NETs. REDD1 in autolysosomes colocalizes with pyrin and nucleotide-binding domain, leucine-rich repeat/pyrin domain-containing 3. Mutated pyrin prohibits this colocalization, leading to higher IL-1ß levels on NETs. CONCLUSIONS: This study provides a link between stress and initiation of inflammatory attacks in patients with FMF. REDD1 emerges as a regulator of neutrophil function upstream to pyrin, is involved in NET release and regulation of IL-1ß, and might constitute an important piece in the IL-1ß-mediated inflammation puzzle.

In June 2008 the first non-imported fatal case of Crimean-Congo hemorrhagic fever (CCHF) was recorded in northern Greece. We present herein the public health interventions and the case definitions we developed for the epidemiological investigation. The possibility of CCHF establishing endemicity in this area is discussed.
