Tobacco smoking prevalence in pregnant women: metanalysis of cross sectional studies
Abstract Background Notwithstanding tobacco smoking during pregnancy is associated with negative health outcomes, its prevalence was not included by worldwide surveillance system. The main objective was to estimate the number of women who had smoked at least one cigarette during her pregnancy in comparison to not smoking women. Methods A systematic review and metanalysis was conducted searching on MEDLINE, Pubmed and Scopus on the 2 January 2020. Keywords were searched with English language limits from 2017 to 2019. Three authors independently screened all titles and abstracts applying the inclusion criteria, extracted the data, filled a database and two other authors assessed doubt eligibi…
Antibodies Responses to SARS-CoV-2 in a Large Cohort of Vaccinated Subjects and Seropositive Patients
COVID-19 is a current global threat, and the characterization of antibody response is vitally important to update vaccine development and strategies. In this study we assessed SARS-CoV-2 antibody concentrations in SARS-CoV-2 positive patients (N = 272) and subjects vaccinated with the BNT162b2 m-RNA COVID-19 vaccine (N = 1256). For each participant, socio-demographic data, COVID-19 vaccination records, serological analyses, and SARS-CoV-2 infection status were collected. IgG antibodies against S1/S2 antigens of SARS-CoV-2 were detected. Almost all vaccinated subjects (99.8%) showed a seropositivity to anti-SARS-COV-2 IgG and more than 80% of vaccinated subjects had IgG concentrations >
Misuse and addiction to mobile phone in a sample of first-grade secondary school students of Palermo
Abstract Background Nowadays, smartphone overuse affects massively teenagers and young adults. From 2014 to 2018 in Italy, for the 11-17 years age group, there has been an increase from 79.9% to 85.8% of daily mobile phone users. This project aims to investigate usage prevalence and misuse/addiction of mobile phones in a representative sample of first-grade secondary school students of the Province of Palermo, Italy, carrying out educational interventions to promote a proper and conscious use of smartphone. Materials and Methods An anonymous, standardized and previously validated pre-intervention questionnaire consisting of 39 items on general socio-demographic characteristics, attitudes an…
Evaluation of the Burden of HPV-Related Hospitalizations as a Useful Tool to Increase Awareness: 2007–2017 Data from the Sicilian Hospital Discharge Records
In light of the implementation of human papillomavirus (HPV) prevention strategies, epidemiological studies in different geographical areas are required in order to assess the impact of HPV-related diseases. The purpose of the present study was to describe the burden of HPV-related hospitalizations in Sicily. A retrospective observational study estimated 43,531 hospitalizations attributable to HPV from 2007 to 2017. During the observed period, there was a decrease for all HPV-related conditions with a higher reduction, among neoplasms, for cervical cancer (annual percent change (APC) = &minus
SARS-CoV-2 Infection in Healthcare Professionals and General Population During “First Wave” of COVID-19 Pandemic: A Cross-Sectional Study Conducted in Sicily, Italy
On December 31, 2019, an outbreak of lower respiratory infections was documented in Wuhan caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Since the beginning, SARS-CoV-2 has caused many infections among healthcare workers (HCWs) worldwide. Aims of this study were: a. to compare the distribution among the HCWs and the general population of SARS-CoV-2 infections in Western Sicily and Italy; b. to describe the characteristics of HCWs infected with SARS-CoV-2 in the western Sicilian healthcare context during the first wave of the epidemic diffusion in Italy. Incidence and mean age of HCWs infected with SARS-CoV-2 were comparable in Western Sicily and in the whole Ita…

PNPLA3 and TLL-1 Polymorphisms as Potential Predictors of Disease Severity in Patients With COVID-19
Albeit the pathogenesis of COVID-19 remains unclear, host’s genetic polymorphisms in genes involved in infection and reinfection, inflammation, or immune stimulation could play a role in determining the course and outcome. We studied in the early phase of pandemic consecutive patients (N = 383) with SARS-CoV-2 infection, whose subsequent clinical course was classified as mild or severe, the latter being characterized by admission to intensive therapy unit or death. Five host gene polymorphisms (MERTK rs4374383, PNPLA3 rs738409, TLL-1 rs17047200, IFNL3 rs1297860, and INFL4 rs368234815) were assessed by using whole nucleic acids extracted from nasopharyngeal swabs. Specific protease cleavage …
