Rotavirus gastroenteritis hospitalization rates and correlation with rotavirus vaccination coverage in Sicily
Background and aim of the works:Rotavirus (RV) is considered the main cause of gastroenteritis in children from 0 to 59 months and vaccination represents the only strategy to prevent hospitalizations due to RV. In 2013 Sicilian Region introduced universal RV vaccination for all newborns. The present study aims to estimate the reduction rotavirus gastroenteritis (RVGE) hospitalization rates among Sicilian children and their relations with vaccination coverages of the nine Sicilian Local Health Units (LHUs). Methods: Were analyzed hospital discharge records including a diagnosis of RVGE occurred from January 2009 to December 2017 in hospitalized children aged 0 to 59 months, residents in Sici…
An Epidemiological Study to Investigate Links between Atmospheric Pollution from Farming and SARS-CoV-2 Mortality.
Exposure to atmospheric particulate matter and nitrogen dioxide has been linked to SARS-CoV-2 infection and death. We hypothesized that long-term exposure to farming-related air pollutants might predispose to an increased risk of COVID-19-related death. To test this hypothesis, we performed an ecological study of five Italian Regions (Piedmont, Lombardy, Veneto, Emilia-Romagna and Sicily), linking all-cause mortality by province (administrative entities within regions) to data on atmospheric concentrations of particulate matter (PM2.5 and PM10) and ammonia (NH3), which are mainly produced by agricultural activities. The study outcome was change in all-cause mortality during March–Apri…
Transmission of Drug-Resistant HIV Type 1 Strains in HAART-Naive Patients: A 5-Year Retrospective Study in Sicily, Italy
The transmission of drug-resistant HIV-1 strains might compromise the efficacy of current first-line antiretroviral (ARV) regimens. Between 2004 and 2008, HIV-1 reverse transcriptase (RT) and protease (PR) genes of 108 ARVnaive Sicilian patients were amplified and sequenced to describe the prevalence of ARV resistance mutations among HAART-naive HIV-1-infected individuals. The frequency of transmitted drug resistance mutations (DRAMs) was determined by using genotypic interpretation algorithms. The proportion of HAART-naive HIV- 1-infected patients in Sicily increased from 18.4% to 23.5% during 2004–2008. Among naive patients, the overall prevalence of DRAMs was 15.7% [17/108; 95% CI: 9.4–2…
Detection of a new 3-base pair insertion mutation in the protease gene of human immunodeficiency virus type 1 during highly active antiretroviral therapy (HAART).
To investigate a new insertion mutation in the protease (PR) gene of human immunodeficiency virus type 1 (HIV-1) in a patient extensively pretreated with antiretroviral drugs, genotypic analyses of plasma-derived viruses were performed by sequencing segments of 1302 nucleotides in the pol gene of HIV-1. Despite optimal compliance to highly active antiretroviral therapy (HAART) the patient showed poor virological success. Nucleotide sequences of retrospective available plasma samples exhibited a previously unknown 3-bp insertion mutation, corresponding to a leucine, between codons 31 and 32 of the PR gene. This kind of mutation appears to be very rare and it does not seem to be associated wi…
The Management of Health Hazards Related to Municipal Solid Waste on Fire in Europe: An Environmental Justice Issue?
Landfilling should be the last option in an integrated Municipal Solid Waste (MSW) management approach. In the European Union (EU), the policy framework to protect the environment and the public health against the impact of health hazards related to urban solid waste management has been consistently implemented in recent decades. A growing interest in the negative impact of fires in waste landfills on the environment and people’s health was reported in some European countries. In Italy, an increasing occurrence of arsons in MSW and landfills has been reported in recent years. During the summer of 2012, a multi-site arson occurred in the Palermo Municipal solid waste landfill of Bellolampo (…
Direct RNA Nanopore Sequencing of SARS-CoV-2 Extracted from Critical Material from Swabs
In consideration of the increasing prevalence of COVID-19 cases in several countries and the resulting demand for unbiased sequencing approaches, we performed a direct RNA sequencing (direct RNA seq.) experiment using critical oropharyngeal swab samples collected from Italian patients infected with SARS-CoV-2 from the Palermo region in Sicily. Here, we identified the sequences SARS-CoV-2 directly in RNA extracted from critical samples using the Oxford Nanopore MinION technology without prior cDNA retrotranscription. Using an appropriate bioinformatics pipeline, we could identify mutations in the nucleocapsid (N) gene, which have been reported previously in studies conducted in other countri…
Are medical residents a "core group" for for future improvement of influenza vaccination coverage in health-care workers? A study among medical residents at the University Hospital of Palermo (Sicily)
Abstract Despite international recommendations, vaccination coverage among European healthcare workers, including physicians, is widely recognized as unsatisfactory. In order to plan tailored vaccination campaigns and increase future coverage, we investigated reasons for refusing vaccination and determinants associated with influenza vaccine uptake among young health care workers. A survey was carried out during September and October 2010 on medical residents attending post-graduate Schools of the Medical Faculty at the University of Palermo (Italy). Each participant completed an anonymous web-based questionnaire including items on demographic and occupational characteristics, knowledge, at…
