A mid-term estimate of 2018/2019 vaccine effectiveness to prevent laboratory confirmed A(H1N1)pdm09 and A(H3N2) influenza cases in Sicily (Italy)
2019
Abstract Influenza season started in Italy during the month of October 2018, approaching the epidemic peak in January 2019. This report aim to explore the mid-term virologic surveillance data of the 2018–2019 influenza season in Sicily and to estimate the effectiveness of seasonal influenza vaccine (VE) against A(H1N1)pdm09 and A(H3N2) influenza viruses. A test-negative design was used to evaluate influenza VE. In Sicily, almost all influenza infections were sustained by influenza type A viruses, of which 62.3% were A(H3N2) and 36.3% A(H1N1)pdm09. A reduction of laboratory confirmed influenza cases in Sicilian population immunized against influenza were observed. In particular, an overall s…
Comparing illicit drug use in 19 European cities through sewage analysis
2012
Abstract: The analysis of sewage for urinary biomarkers of illicit drugs is a promising and complementary approach for estimating the use of these substances in the general population. For the first time, this approach was simultaneously applied in 19 European cities, making it possible to directly compare illicit drug loads in Europe over a 1-week period. An inter-laboratory comparison study was performed to evaluate the analytical performance of the participating laboratories. Raw 24-hour composite sewage samples were collected from 19 European cities during a single week in March 2011 and analyzed for the urinary biomarkers of cocaine, amphetamine, ecstasy, methamphetamine and cannabis u…
Rôles des cellules myéloïdes suppressives et des infiltrats immunitaires dans le cancer
2013
Immune system plays a dual role in cancer: it can not only suppress tumor growth by destroying cancer cells, but also promote tumor progression by selecting immunoresistant tumor cells or by establishing an immunosuppressive microenvironment. Our main objective is to foster on the context of immune response in colon cancer settingDuring my thesis, I focused on one population of the immunosuppressive cells immune system: MDSC (myeloid derived suppressor cells). In this work, we explored strategies to reduce the number of these cells during tumor growth. We have discovered that small doses of 5 Fluorouracil are able to specifically induce apoptotic death of MDSC. We have characterized a novel…
The Role of Novel Bladder Cancer Diagnostic and Surveillance Biomarkers—What Should a Urologist Really Know?
2022
The aim of this review is to analyze and describe the current landscape of bladder cancer diagnostic and surveillance biomarkers. We researched the literature from 2016 to November 2021 to find the most promising new molecules and divided them into seven different subgroups based on their function and location in the cell. Although cystoscopy and cytology are still the gold standard for diagnosis and surveillance when it comes to bladder cancer (BCa), their cost is quite a burden for national health systems worldwide. Currently, the research is focused on finding a biomarker that has high negative predictive value (NPV) and can exclude with a certainty the presence of the tumor, considering…
Sprawa operacyjnego sprawdzenia kryptonim „Zakonnik”. inwigilacja ks. Henryka Surmy przez Służbę Bezpieczeństwa w latach 1974-1977
2018
Celem opracowania jest ukazanie na przykładzie jednego z zakonników sposobu postępowania Służby Bezpieczeństwa wobec duchownych, którzy znaleźli się w spektrum zainteresowania tej instytucji, z uwagi na podejrzenie prowadzenia „antypaństwowej” działalności. Tego rodzaju sprawy operacyjnego sprawdzenia zakładane były przez Służbę Bezpieczeństwa PRL bardzo często i miały na celu sprawdzenie doniesień o prowadzeniu przez duchownych działalności uznawanej przez władze komunistyczne za wrogą ustrojowi PRL. Ks. Henryk Surma, nie godząc się na komunistyczne ograniczenia praw człowieka, ani na dążenia władz PRL zmierzające do marginalizacji Kościoła, próbował na własną rękę pozyskać środki na remon…
Anomaly Detection in Traffic Surveillance Videos Using Deep Learning
2022
In the recent past, a huge number of cameras have been placed in a variety of public and private areas for the purposes of surveillance, the monitoring of abnormal human actions, and traffic surveillance. The detection and recognition of abnormal activity in a real-world environment is a big challenge, as there can be many types of alarming and abnormal activities, such as theft, violence, and accidents. This research deals with accidents in traffic videos. In the modern world, video traffic surveillance cameras (VTSS) are used for traffic surveillance and monitoring. As the population is increasing drastically, the likelihood of accidents is also increasing. The VTSS is used to detect abno…

Data quality of 5 years of central norovirus outbreak reporting in the European Network for food-borne viruses
2008
ABSTRACT Background The food-borne viruses in Europe (FBVE) network database was established in 1999 to monitor trends in outbreaks of gastroenteritisdue to noroviruses (NoVs), to identify major transmission routes of NoV infections within and between participating countries and to detectdiffuse international food-borne outbreaks.Methods We reviewed the total of 9430 NoVoutbreak reports from 13 countries with date of onset between 1 January 2002 and 1 January2007 for representativeness, completeness and timeliness against these objectives.Results Rates of reporting ranged from a yearly average of 1.8 in 2003 to 11.6 in 2006. Completeness of reporting of an agreed minimumdataset improved ove…
A METHODOLOGY DEVELOPMENT FOR A WEB-BASED SURVEILLANCE SYSTEM OF ADOLESCENT FOOD HABITS AND LIFESTYLES – THE ASSO PROJECT
2012
ASSO Project (Adolescents Surveillance System and Obesity prevention) is a study financed by the Italian Ministry of Health, aimed at developing an innovative web-based system for a standardized collection of data on food consumptions, lifestyles and body size in the adolescents attending high schools. One of the main objectives of the project is to develop user-friendly and cost-effective tools to create a web-based software. A Systematic Literature Review (SLR) on the most valid dietary and physical activity/fitness assessment methods used in the target population has been perfomed. The implementation of the software is being done by using JAVA and the data archive system is based on MySQ…
Wastewater-based epidemiology for early warning of SARS-COV-2 circulation: A pilot study conducted in Sicily, Italy
2022
There is increasing evidence of the use of wastewater-based epidemiology to integrate conventional monitoring assessing disease symptoms and signs of viruses in a specific territory. We present the results of SARS-CoV-2 environmental surveillance activity in wastewater samples collected between September 2020 and July 2021 in 9 wastewater treatment plants (WTPs) located in central and western Sicily, serving over 570,000 residents. The presence of SARS-CoV-2, determined in 206 wastewater samples using RT-qPCR assays, was correlated with the notified and geo-referenced cases on the areas served by the WTPs in the same study period. Overall, 51% of wastewater samples were positive. Samples we…
