Comparison of Different Chemical and Mechanical Modalities for Implant Surface Decontamination: Activity against Biofilm and Influence on Cellular Regrowth-An Study.

Objectives: The aim of this study was to compare the efficacy of chemical and mechanical methods for decontamination of titanium dental implant surfaces previously infected with polymicrobial biofilms in a model simulating a peri-implant defect. Furthermore, the effect of each decontamination protocol on MG-63 osteoblast-like cells morphology and adhesion to the treated implants was assessed.

Background: Peri-implantitis is a growing issue in dentistry, and evidence about implant surface decontamination procedures is lacking and inconclusive.

Determinants of SARS-CoV-2 infection in Italian healthcare workers: a multicenter study.

Healthcare workers (HCWs) are at increased risk of being infected with SARS-CoV-2, yet limited information is available on risk factors of infection. We pooled data on occupational surveillance of 10,654 HCW who were tested for SARS-CoV-2 infection in six Italian centers. Information was available on demographics, job title, department of employment, source of exposure, use of personal protective equipment (PPEs), and COVID-19-related symptoms.

Gluten-free meals in public catering.

Background: The Piedmont Region, the Food Hygiene and Nutrition Services of the Local Healthcare Authorities of the Piedmont Region (coordinated by ASL TO 3), and the Italian Coeliac Association Piedmont Onlus, have created a theoretical-practical training pathway for Food Business Operators to ensure a safe gluten-free meal.

Study Design: The aim of the study is to perform a retrospective analysis of the data collected in order to assess whether the Food Business Operators will be able to manage in the short, medium and long term audits (3-month audits, 6-month audits and 1-year audits) all the production stages of a gluten-free meal (storage, production.

Methods: We have analysed the check-list used for assessing the gluten free meal, recorded from 2010 to 2016 by the staff of the Food Hygiene and Nutrition Services.

Renal Allograft Biopsies with Polyomavirus BK Nephropathy: Turin Transplant Center, 2015-19.

Background: In kidney transplant patients, polyomavirus-associated nephropathy (PVAN) represents a serious complication; the key factor for the development of PVAN is immunosuppression level and modulation of anti-rejection treatment represents the first line of intervention. Allograft biopsy and histology remain the criterion standard for diagnosing PVAN.

Methods: All consecutive renal biopsies with the diagnosis of PVAN carried out at the University Hospital City of Health and Science of Turin over a five-years period were studied.
