Anti-SARS-CoV-2 IgG antibodies induced by the BNT162b2 mRNA vaccine is age-dependent and influenced by a previous natural SARS-CoV-2 infection.

Background And Aim: our study aimed to investigate the association between anti-SARS-CoV-2 IgG level after two doses of BNT162b2 vaccine and the previously infected/infection-naïve status, age, and gender in a population of health care workers (HCWs).

Methods: all the population of immunocompetent HCWs were vaccinated with two doses of BNT162b2 based on a technical data sheet. SARS-CoV-2 IgG assay was performed 25 to 32 days after the second dose.

[Training and information interventions aimed at stress control in the health care sector: potentialities and limits].

Training programs for health care workers aimed at controlling job-related stress (person-directed, person-work interface and organizational interventions) demonstrate only short-term effect in reducing stress levels. Medium-long-term results could be achieved only through well-articulated programs, which involve health administration managers and nursing staff in a solid and enduring prevention-centered approach. Informative interventions conducted in hospital for preventing job-related stress have a particularly good response rate among nurses and other members of medical support and technical staff.

["Work related stress" and health care: clinical cases and work-fitness" evaluation].

In the last years an increasing number of people is coming in observation at the Hospital Units of Occupational Medicine in Lombardia, with several "work related stress diseases", showing various clinical manifestations, from light depressive syndromes to severe psychiatric pathologies. Since 1994 the occupational physicians in Lombardia are involved in the "stress related problems" at the workplaces (see SIMLII Symposium in Milan). Furthermore, a specific research project in the years 2004-2007 describes the real dimension of the problem in the different production fields in Lombardia.
