Abstract
Abstract
Background
The British Columbia Colon Screening Program (BCCSP) is a population-based program enrolling 50–74 year old individuals for biennial FIT (OC-Sensor, cut-off 10 mcg/g) with follow-up colonoscopy for positive FIT. The neoplasia detection rate is 50–55% and over 75% of colonoscopies have a specimen taken. Previously reported colonoscopy adverse event rates for FIT based screening programs vary widely: 0.03–6.2% and 0–2.7% for bleeding and perforation, respectively. Mortality as a result of colonoscopy is rare but has been reported in 0.0004%-0.0074% of colonoscopies. The rate of colonoscopy related adverse events in BCCSP participants is unknown.
Aims
To determine the rate of colonoscopy related serious adverse events within the BCCSP.
Methods
This is a retrospective cohort study of all participants undergoing colonoscopy in BCCSP from November 15, 2013 to December 31, 2017. BCCSP contacts screening participants by phone 14 days post colonoscopy to determine unplanned medical visits the day prior (during bowel preparation) or following the colonoscopy. Unplanned events underwent chart review if the event was a perforation, cardiovascular or respiratory event, or resulted in death, hospitalization, or significant intervention including repeat colonoscopy, interventional radiology, surgery, blood transfusion, cardioversion, casting of a fracture or suturing of a laceration. Chart review was conducted by a Colonoscopy Lead and reviewed by BCCSP Quality Committee. Unplanned events were defined as serious adverse events (SAE) if they resulted in death, hospitalization or significant intervention and further classified as probably, possibly, or unlikely related to the colonoscopy.
Results
A total of 108,004 colonoscopies were performed. Unplanned events were reported in 1753 participants, of which 586 met criteria for review. Of these, 578 were confirmed unplanned events and 409 were SAEs of which 367 (89.7%) were probably, 22 (5.4%) possibly and 20 (4.9%) unlikely associated with colonoscopy. 36/10,000 colonoscopies were associated with a SAE that was probably or possibly related: perforation in 5/10,000, bleeding 22/10,000. Three deaths occurred in the 14 days following colonoscopy that were probably (2 perforations) or possibly related to the colonoscopy (0.3/10,000).
Conclusions
The BCCSP has a colonoscopy SAE rate in keeping with previous publications, particularly in the context of a very high proportion of procedures associated with polypectomy, a known risk factor for perforation and bleeding. This study will help inform screening participants about the risks of colonoscopy in the BC program. Future studies are required to confirm these rates using hospital admission data.

Abstract
BACKGROUND Colorectal cancer (CRC) screening is an evidence-based strategy to reduce CRC-related mortality. OBJECTIVE This study identifies physician and participant characteristics, as well as previous FIT values associated with premature FIT usage. DESIGN This is a retrospective review of all FITs ordered from January 1, 2016, until June 30, 2017. For each ordered FIT, the participant's chart was reviewed to identify if a previous FIT had occurred in the prior 21 months. A premature FIT was defined as an ordered test with a negative FIT in the preceding 21 months. PARTICIPANTS Screening participants were average risk for CRC, aged 50-74, and had a FIT ordered by their primary care provider in British Columbia, Canada. MAIN MEASURES The BC College of Physicians and Surgeons' database was used to identify the location of referring physician, date of graduation from medical school, and gender. The participant's age, gender, and value of previous FIT were recorded. Physician and participant variables and previous FIT value were examined with logistic regression to identify associations with premature FIT ordering. KEY RESULTS In total, 385,375 FITs were ordered during this period with 116,727 representing participants returning following a previous negative FIT. In total, 35,148 (30.1%) returned early for screening. Men were more likely to return early than women (OR 1.14; 95% CI 1.11-1.17; p < 0.0001). Male physicians were more likely to order premature FITs (OR 1.15; 95% CI 1.06-1.24; p < 0.0001). A higher quantitative FIT value (ng/mL) of the previous FIT was also associated with early screening (OR 1.11; 95% CI 1.09-1.14; < 0.0001). CONCLUSIONS This study found that approximately 30% of FIT tests, ordered for CRC screening, were ordered before they were due. This may lead to wasted resources, unnecessary participant stress, and unwarranted patient risk.

Abstract
INTRODUCTION Among the health professions with a long period of training, the students of the Nursing Bachelor's Degree are the most exposed to biological risk resulting from accidents, in particular with needles and cutting edges. The aim of the study was to estimate the frequency and the circumstances for the occurrence of needle stick injuries, as a knowledge base for targeted prevention interventions. METHODS The study was carried out between May and July 2017 in 11 Universities in Italy and 1 in Albania (associated with the "Tor Vergata" University of Rome). An anonymous semi-structured questionnaire was proposed to 1st (second semester), 2nd and 3rd year students of Nursing Bachelor's Degree. RESULTS A total of 2742 questionnaires were collected. The average age of participants was 22.9 years (median 22, range 19-60 years), 73% of whom were females. A total of 381 injuries were reported. Three hundred and sixteen students (11.8%) underwent at least 1 injury (12.7% among females, 9.7% among males); 41 students declared two or more injuries; four students did not report the number of injuries occurred. The first injury occurred, as an average, 17 days after the start of the internship (median 15 days) and, in 25% of the cases, during the first 9 days. The highest percentage of accidents occurred during the first internship (25.3% of the total) and decreased with the progress of the training path. The injuries occurred in 38% of cases during drug preparation, 24% when disposing of sharp devices, 15% while re-capping needles, 13% during blood sampling and 10% in other circumstances. In 51.2% of cases, the needle was not sterile. Among the nursing students who suffered a needle stick injury, 58.1% declared that they had performed the post-exposure prophylaxis. 96% of students stated to be vaccinated against Hepatitis B virus. Amongst the students who had their serological status checked (74%), 18% stated the antibody titre was not protective. 49.8% of students answered to have been trained in advance on the correct procedures to avoid needle stick and cutting edges injuries in each clinical ward attended, 41.2% referred that this occurred only in some wards and 10% in no ward at all. CONCLUSION The results of this study show a high percentage of needle stick injuries in students of the Nursing Bachelor's Degree. Therefore, there is a need for careful reflection on the most effective methods of targeted training acquisition of knowledge, skills and behavioural models useful for the exercise of the profession.

Abstract
In Italy, to show the willingness to donate one's organs, there is the principle of the explicit consensus (or disagreement) (Law n. 91 of the 01.04.1999, Art. 23; Decree of the Italian Health Ministry of the 08.04.2000). According to data of the Italian Association for the donation of organs, tissues and cells (AIDO), in 2017 in Campania Region (Southern Italy) an average of 12.5 people x1,000,000 donated their organs vs. a national average of 23.7. This negative discrepancy between national and regional data highlights that it is imperative to promote awareness-raising measures to address to the population of Campania Region in order to improve the following of a practice which is still object of preconceptions and scarce knowledge. This paper describes a pilot project started in 2017 by the "Sportello amico trapianti" (friendly access to transplantation) to promote the donation of organs within the university-hospital "Federico II" (Naples, Campania Region). The first phase of this project was based on the nudge theory, that is the "little push" to direct decisional processes of groups and individuals. This phase took place during the "Atelier della salute" (a health workshop), organized by the Medicine and Surgery school of the university-hospital "Federico II": here, a questionnaire was administered to 60 people. The questionnaire consisted in 12 questions, answered by volunteers, which aim was to test the general knowledge about organ donation and transplantation. Analysing the answers, a panel of 7 experts (2 epidemiologists, 1 social worker, 2 experts in public and institutional communication, 1 biologist expert in donation of haematopoietic progenitor cell, 1 transplant surgeon), responsible for the coordination and monitoring of the activities, identified the critical elements to bring attention to in order to raise awareness in the population. The second phase consisted in a literary workshop which aim was to identify nudge cases. The text used was Never let me go by Kazuo Ishiguro, a novel focused on organ donation in a dystopic context where the protagonists are clones created to facilitate the donation of organs. Six students participated in this workshop: all six considered the dystopic scenario as a potential nudge to humanize the approach to organ donation and transplant. In conclusion, we believe that the nudge methodology may be used in order to improve awareness and adherence to donation of organs.

Abstract
IMPORTANCE There is limited information about the relative effectiveness of cervical cancer screening with primary human papillomavirus (HPV) testing alone compared with cytology in North American populations. OBJECTIVE To evaluate histologically confirmed cumulative incident cervical intraepithelial neoplasia (CIN) grade 3 or worse (CIN3+) detected up to and including 48 months by primary HPV testing alone (intervention) or liquid-based cytology (control). DESIGN, SETTING, AND PARTICIPANTS Randomized clinical trial conducted in an organized Cervical Cancer Screening Program in Canada. Participants were recruited through 224 collaborating clinicians from January 2008 to May 2012, with follow-up through December 2016. Women aged 25 to 65 years with no history of CIN2+ in the past 5 years, no history of invasive cervical cancer, or no history of hysterectomy; who have not received a Papanicolaou test within the past 12 months; and who were not receiving immunosuppressive therapy were eligible. INTERVENTIONS A total of 19 009 women were randomized to the intervention (n = 9552) and control (n = 9457) groups. Women in the intervention group received HPV testing; those whose results were negative returned at 48 months. Women in the control group received liquid-based cytology (LBC) testing; those whose results were negative returned at 24 months for LBC. Women in the control group who were negative at 24 months returned at 48 months. At 48-month exit, both groups received HPV and LBC co-testing. MAIN OUTCOMES AND MEASURES The primary outcome was the cumulative incidence of CIN3+ 48 months following randomization. The cumulative incidence of CIN2+ was a secondary outcome. RESULTS Among 19 009 women who were randomized (mean age, 45 years [10th-90th percentile, 30-59]), 16 374 (8296 [86.9%] in the intervention group and 8078 [85.4%] in the control group) completed the study. At 48 months, significantly fewer CIN3+ and CIN2+ were detected in the intervention vs control group. The CIN3+ incidence rate was 2.3/1000 (95% CI, 1.5-3.5) in the intervention group and 5.5/1000 (95% CI, 4.2-7.2) in the control group. The CIN3+ risk ratio was 0.42 (95% CI, 0.25-0.69). The CIN2+ incidence rate at 48 months was 5.0/1000 (95% CI, 3.8-6.7) in the intervention group and 10.6/1000 (95% CI, 8.7-12.9) in the control group. The CIN2+ risk ratio was 0.47 (95% CI, 0.34-0.67). Baseline HPV-negative women had a significantly lower cumulative incidence of CIN3+ at 48 months than cytology-negative women (CIN3+ incidence rate, 1.4/1000 [95% CI, 0.8-2.4]; CIN3+ risk ratio, 0.25 [95% CI, 0.13-0.48]). CONCLUSIONS AND RELEVANCE Among women undergoing cervical cancer screening, the use of primary HPV testing compared with cytology testing resulted in a significantly lower likelihood of CIN3+ at 48 months. Further research is needed to understand long-term clinical outcomes as well as cost-effectiveness. TRIAL REGISTRATION isrctn.org Identifier: ISRCTN79347302.

Abstract
BACKGROUND The circulatory diseases, in particular ischemic heart diseases and stroke, represent the main causes of death worldwide both in high income and in middle and low income countries. Our aim is to provide a comprehensive report to depict the circulatory disease mortality in Europe over the last 30 years and to address the sources of heterogeneity among different countries. METHODS Our study was performed using the WHO statistical information system - mortality database - and was restricted to the 28 countries belonging to the European Union (EU-28). We evaluated gender and age time series of all circulatory disease mortality, ischemic heart diseases, cerebrovascular diseases, pulmonary and other circulatory diseases and than we performed forecast for 2016. Mortality heterogeneity was evaluated by countries using the Cochrane Q statistic and the I-squared index. RESULTS Between 1985 and 2011 SDR for deaths attributable to all circulatory system diseases decreased from 440.9 to 212.0 x 100,000 in EU-28 and a clear uniform reduction was observed. Heterogeneity among countries was found to be consistent, therefore different analysis were carried out considering geographical area. CONCLUSIONS We forecast a reduction in European cardiovascular mortality. Heterogeneity among countries could only in part be explained by both geographical and health expenditure factors.

Abstract
INTRODUCTION In the European Union three different health systems could be defined according to service delivery, financing, and economic policies: Beveridge, Bismarck and Mixed system. Although health systems are hardly to compare, various organizations are developing methods assessing performance. In the present work the performance of the three systems were evaluated using European Community Health Indicators according to Organization for Economic Cooperation and Development. METHODS The study has been conducted among the 28 states of the European Union using the following indicators: Standardized death rate for diseases of the circulatory system, standardized death rate of malignant neoplasms, road traffic accidents with injury, life expectancy at birth, incidence of Human Immunodeficiency Virus (HIV), infant deaths, pure alcohol consumption, infants vaccinated against Diphtheria Tetanus Pertussis (DTP), public and total expenditure on health over the period 2001-2010. RESULTS The variation of health indicators over the observational time shows similar trend of circulatory system diseases and malignant neoplasms death rates, road accidents with injury, infant deaths, life expectancy at birth, public and total health expenditure. Some differences in the trend of HIV incidence, alcohol intake and DTP vaccination rates arise among systems. Grouping countries by health system paradigm and geographical area, resulted in a relevant heterogeneity (I2 ≥ 90%, Pvalue < 0.0001). No clear superiority of a given health delivery system was found with respect to other paradigms. CONCLUSIONS In accordance with the evidence of our study, it can be stated that best performances are more likely to be linked to country specific economic factors. In conclusion, it was not possible to identify the best health system model.

Abstract
BACKGROUND British Columbia undertook a colorectal cancer screening pilot program in 3 communities. Our objective was to assess the performance of 2-specimen fecal immunochemical testing in the detection of colorectal neoplasms in this population-based screening program. METHODS A prospective cohort of asymptomatic, average-risk people aged 50 to 74 years completed 2 quantitative fecal immunochemical tests every 2 years, with follow-up colonoscopy if the result of either test was positive. Participant demographics, fecal immunochemical test results, colonoscopy quality indicators and pathology results were recorded. Non-screen-detected colorectal cancer that developed in program participants was identified through review of data from the BC Cancer Registry. RESULTS A total of 16 234 people completed a first round of fecal immunochemical testing, with a positivity rate of 8.6%; 5378 (86.0% of eligible participants) completed a second round before the end of the pilot program, with a positivity rate of 6.7%. Of the 1756 who had a positive test result, 1555 (88.6%) underwent colonoscopy. The detection rate of colorectal cancer was 3.5 per 1000 participants. The positive predictive value of the fecal immunochemical test was 4.9% (95% confidence interval [CI] 3.8%-6.0%) for colorectal cancer, 35.0% (95% CI 32.5%-37.2%) for high-risk polyps and 62.0% (95% CI 59.6%-64.4%) for all neoplasms. The number needed to screen was 283 to detect 1 cancer, 40 to detect 1 high-risk polyp and 22 to detect any neoplasm. INTERPRETATION Screening every 2 years with a 2-specimen fecal immunochemical test surpassed the current benchmark for colorectal cancer detection in population-based screening. This study has implications for other jurisdictions planning colorectal cancer screening programs.

Abstract
Bigels are biphasic systems produced with an organogel (or oleogel) and a hydrogel mixed together at high shear rates. These systems are promising for different uses, among them the formulation of new cosmetic matrices for cosmetic agents delivery is under investigation. In the present paper, a common cosmetic formulation for skin care was enriched with increasing fractions of monoglycerides of fatty acids/olive oil organogels, in order to understand the rheology and the microstructure of these systems. Small amplitude oscillation tests, NMR-self diffusion analysis, contrast phase microscopy and electric conductivity confirmed that the addition of the organogel caused a microstructural change of the starting material, which turned from O/W to a more complex system where, probably, a matrix-in-matrix structure is present at the highest fractions of added organogel.

Abstract
The peptide GSFSIQYTYHV derived from human semenogelin I forms a transparent hydrogel through spontaneous self-assembly in water at neutral pH. Linear rheology measurements demonstrate that the gel shows a dominating elastic response over a large frequency interval. CD, fluorescence and FTIR spectroscopy and cryo-TEM studies imply long fibrillar aggregates of extended β-sheet. Dynamic light scattering data indicate that the fibril lengths are of the order of micrometers. Time-dependent thioflavin T fluorescence shows that fibril formation by GSFSIQYTYHV is a nucleated reaction. The peptide may serve as basis for development of smart biomaterials of low immunogenicity suitable for biomedical applications, including drug delivery and wound healing.

Abstract
AIM The association between high-normal blood pressure and the impairment of renal function is highly controversial. We analysed the contribution of high-normal blood pressure on incident impaired renal function. METHODS The study was performed in a population-based cohort of 1307 subjects free of diabetes, cardiovascular and renal disease at baseline, who attended both at baseline and after 6-year follow-up a metabolic screening. The outcome was incident impaired renal function, defined as a glomerular filtration rate <60 mL/min/1.73 m2. RESULTS Incidence of impaired renal function was 2.5%, 4.5%, 8.7% and 10.8% in optimal, normal, high-normal blood pressure and hypertension, respectively. Adjusted relative odds ratio (OR) of impaired renal function were modelled using logistic regression analyses including multiple confounders. The adjusted OR were 1.6 (95% CI 0.5-5.0) for normal blood pressure, 3.4 (1.2-10.3) for high-normal blood pressure and 3.7 (1.3-10.7) for hypertension. Results were similar after excluding overweight or obese patients. CONCLUSION High-normal blood pressure is an independent predictor of impaired renal function. Trials are warranted to test if therapeutic intervention on blood pressure is justified also in subjects with high-normal blood pressure to preserve renal function.
