RESUMO
In October/December 2021, World Health Organization and other international agencies recommended the offer of the third dose of anti-SARS-CoV-2 vaccine. In this period, the routine offer of seasonal influenza vaccination was also guaranteed and simultaneous administration of the two vaccines was encouraged. This study aims to evaluate the safety profile and to estimate the incidence of SARS-CoV-2 breakthrough infections in subjects receiving the anti-SARS-CoV-2 and influenza vaccines simultaneously. The study population was represented by healthcare workers (HCWs) of Bari Policlinico General Hospital who received the influenza (Flucelvax Tetra®) and/or anti-SARS-CoV-2 vaccination (BNT162b2 mRNA COVID-19 vaccine, Comirnaty®) either in coadministration or separately in October 2021. Reports of adverse events following immunization (AEFIs) were investigated to study the safety of both vaccines in coadministration and in separate-instance administration. Post-vaccination SARS-CoV-2 breakthrough infection was also studied. 942 HCWs accepted to join our study. 610/942 received both vaccines simultaneously. 25.26 % subjects (238/942) were only vaccinated against SARS-CoV-2, while the remaining 94 HCWs received the influenza vaccination first and subsequently received the anti-SARS-CoV2 booster dose. 717 HCWs reported AEFIs (Reporting Rate 76.1 per 100 subjects). Simultaneous administration of the two vaccines was not related with an increase of the rate of AEFIs compared to the single administration of SARS-CoV-2 vaccine, but the AEFIs' rate was lower among subjects who received only influenza vaccine. Post-vaccination SARS-CoV-2 infections were notified for 41.5 % of enrolled subjects (391/942). Incidence of breakthrough infection and symptomatic disease was not significantly different between the simultaneous administration group and other subjects. Our data suggests that simultaneous administration of a quadrivalent influenza vaccine and an mRNA anti-SARS-CoV-2 vaccine neither affected the safety of said products nor was associated with a higher risk of SARS-CoV-2 breakthrough infection.

Background: Nowadays, two types of anti-pneumococcal vaccine are available: pneumococcal 13-valent conjugate vaccine (PCV13), first licensed in the United States (US) in 2013, and pneumococcal 23-valent polysaccaridic vaccine (PPSV23), first licensed in the US in 1999. These vaccines are recommended in Italy for the immunization of newborns and of the elderly, using a combined sequential schedule for the latter. This report aims to describe the PCV13- and PPSV23-related AEFIs notified in Puglia in 2013-2020, in order to design these products' safety profile in a real-life scenario, three years after the official recommendation about the sequential schedule for people over 60 years of age. Methods: This is a retrospective observational study. Data were gathered from the list of AEFIs notified following PCV13 and PPSV23 administration in Puglia in 2013-2020. The number of administered vaccine doses was obtained from the regional immunization database. AEFIs were classified according to WHO's algorithm, and causality assessment was carried out in case of serious AEFIs. Results: From January 2013 to December 2020, 764,183 doses of PCV13 and 40,382 doses of PPSV23 were administered in Puglia. In the same period, 71 PCV13 AEFIs (Reporting Rate: 9.29 x100,000 doses) and 5 PPSV23 AEFIs (Reporting Rate: 12.4 x100,000 doses) were reported. The overall male/female ratio in AEFIs was 0.85. The majority of AEFIs occurred in subjects aged less than 2 (64/76, 84.2%), while 10 out of 76 (13.2%) occurred in patients aged 60 or older. 22 AEFIs were classified as serious and for 12 (54.5%) causality assessment showed a consistent relationship with immunization. The most commonly reported symptoms were fever (Reporting Rate: 4.72 x100,000 doses) and neurological symptoms (Reporting Rate: 3.23 x100,000 doses). Only one death was notified, classified as non-vaccine-related. Conclusions: The benefit of pneumococcal vaccination appears to be greater than the risk of AEFIs for both PCV13 and PPSV23. In fact, AEFIs occur in less than 0.1 of patients and the majority of AEFIs are mild and self-limiting.

Introduction: Healthcare workers on duty at the hospital are at high risk of COVID-19 infection. However, despite the introduction of risk-lowering practices in the hospital setting, there have been many cases of SARS-COV-2 infection among Health Care Workers. Fast and efficient contact tracing and Sars-CoV-2 PCR-based testing of the close contacts of Health Care Workers with confirmed infections are essential steps to limit nosocomial outbreaks. Methods: This cross-sectional study was conducted at Bari Policlinico General University-Hospital (Apulia, Italy) and describes the management of a cluster of SARS-COV-2 infections in three Operative Units. The contact tracing activities and the measures implemented to control the outbreak are described. Results: Among the 186 Health Care Workers active in the cluster setting, there were 9 (4.8%) confirmed cases, including the index case. Due to the outbreak, three Operative Units were closed to limit virus circulation. Health Care Workers with confirmed infections tested negative after a mean of 28.0±6.6 days (range: 13-37) and none required hospitalization. Conclusions: Protection of the health of Health Care Workers during the COVID-19 pandemic should be a public health priority. However, despite recent recommendations and the implementation of protective measures, SARS-COV-2 infections of Health Care Workers remain at a high rate, indicative of the continued high risk of cluster onset in the nosocomial setting.

Background: As other indoor sports facilities, swimming pools were closed in Italy from March to May 2020 and from October 2020 to July 2021 due to the outbreak of the COVID-19 pandemic; access to these facilities was restricted to athletes of national relevance. This decision was based on "precautionary principles" and without evidence of a high risk of SARS-COV-2 circulation among swimming pools' attendants. The aim of this paper is to describe the pattern of SARS-COV-2 circulation among swimming athletes in Apulia (Southern Italy). Study design: The study aims to investigate the hypothesis that attending a pool increases the risk of SARS-COV-2 infection. The outcome measure is the incidence of SARS-COV-2 infection among swimming athletes compared with the general population. Methods: This is a retrospective cross-sectional study carried out in Apulia, Southern Italy. The study was performed through the analysis of both the database of the Italian Swimming Federation and the SARS-COV-2 infections in Apulia Region, from July 2020 to August 2021. Results: Among 2,939 federally licensed athletes, 221 had an history of SARS-COV-2 infection from July 2020 to August 2021, with an incidence of 75.2 /1,000. In the general Apulian population, during the same time span, the incidence of SARS-COV-2 infection was 67.3/1,000 and - considering the incidence rate ratio - there is no difference between the two populations (IRR=1.1; 95% CI=0.9-1.3; p>0.05). Conclusions: The incidence of SARS-COV-2 infection in Apulian swimmers showed no significant differences with the general population.

Background: The COVID-19 emergency has highlighted the importance of prevention systems and environ-mental microbiological monitoring as fundamental elements in the response to epidemics and other such threats to individual and collective health. The use of automated "No-touch" room disinfection systems eliminates or reduces the dependence on operators, thus allowing an improvement in the effectiveness of terminal disinfection. Study design: In the present study, we focused on possible SARS-CoV-2 contamination of surfaces of com-mercial services, and the effectiveness of ozone treatment on the virus. Methods: Analyses were conducted on 4-7 October and 27-30 December 2021 in four supermarkets in an Apulian city; supermarkets A and B were equipped with an ozonisation system, while C and D were without any environmental remediation. Results: SARS-CoV-2 RNA was detected by real-time RT-PCR only in December, in 6% of the surfaces tested, and all examined samples were found to be negative after viral culture, since no cytopathic effect was observed. A statistically significant difference emerged from the comparison of October vs. December (p = 0.0289), but no statistically significant difference (p = 0.6777) emerged from the comparison between supermarkets with and without the ozonisation system. Conclusions: Although no important changes were observed by treating the environments with ozonisation systems, further studies are needed to validate the effectiveness of environmental treatments with airborne disinfectants.

Foreward: Nurses' attitudes towards COVID-19 vaccination is a relevant issue, for the protection of the vulnerable people they care for, and the key role they play in promoting health behaviors that encourage trust and adherence to vaccination among population. This study aimed to validate the Italian version of the Vaccination Attitudes Examination (VAX) scale and to describe nurses' attitudes towards COVID-19 vaccination. Design: A cross-sectional study was carried out from May to June 2021. Descriptive statistics, Explorative and Confirmatory Factor Analyses have been performed. Methods: An online survey was carried out in Italy. The VAX scale referring to the COVID-19 vaccine was used. Findings: 430 nurses participated in the study, mainly female (73.2%). Mean age was 40.2 years. VAX scale revealed an optimal reliability; Exploratory Factor Analysis and Confirmatory Analysis supported a 4-factors model. VAX scale mean scores showed low mistrust about vaccine's benefit (2.03±1.07), concerns about commercial profiteering (2.33±1.39) and preference for natural immunity (2.90±1.37). More worries concerning unexpected future effects were found (4.46±1.36). Gender, taking care of a frail person in family, having children or working in a COVID-19 setting are no significantly related to vaccination attitude. Participants from northern Italy expressed greater confidence in vaccine's benefits, the younger had significant lower scores about commercial profiteering. Conclusions: The Italian version of the VAX scale resulted a reliable tool to assess the nurses' attitudes towards COVID-19 vaccination. An overall positive nurses' attitude towards the COVID-19 vaccination was highlighted. The concern about unforeseen future effects suggested the need to increase the information on this issue. Clinical relevance: The results provided a valid and reliable tool to measure vaccination attitudes in the Italian context. This study could strengthen the health policies with educational interventions of healthcare workers through specific vaccination pathways. The healthcare professionals' vaccination attitudes play the key role also in promoting vaccination uptake in the population.

the SARS-CoV-2 pandemic started in December 2019 and still remains a major global health issue. Every country in the world has adopted drastic measures to contain the virus, although their stringency varies among countries, ranging from increased surveillance and focused interventions to strict lockdown (1). Italy was the second country where the disease had a major impact early in the pandemic, such that a strict nationwide lockdown was declared from March 9 to May 3, 2020. Nonetheless, between January and May 2020, there were 210,000 COVID-19 cases in Italy and 29,000 deaths were recorded (2). Due to the lockdown, universities (and in general all educational services) shifted to online classes, with students attending lessons and taking their exams from home. On-site activities were reduced to those considered indispensable. Research activities also had to be modified, such as by the adoption of a smart-working model (3). Between May and August 2020, the number of SARS-CoV-2 infections in Italy decreased. In response, the lockdown was loosened and some activities were restarted, albeit with specific safety protocols (social distancing, use of masks, temperature checks at the workplace entry, environmental disinfection, mixed models of smart and in-office work). These actions were accompanied by periodic serological and PCR screening tests (4).

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2)-related infection has a major impact on public health, and healthcare workers (HCWs) are exposed to high biological risk. This paper describes the prevention procedures introduced at the University Hospital of Bari, Italy to reduce the risk to HCWs, consisting of enhanced preventive measures and activation of a report system to collect HCWs' contacts. Twenty-three confirmed cases of infection (0.4% of all HCWs) were reported in the 30-day observation period following implementation of the protocol. This shows that correct management of HCWs' contacts is essential to avoid nosocomial clusters.

BACKGROUND: Studies on the relationship between sport and smoking among adolescents and young adults reported contradictory results: some findings indicate that sport is a protective factor against smoking initiation, while other studies documented the inclination to unhealthy habits among athletes. The aim of this study was to evaluate smoking prevalence in a sample of young athletes practicing team (football, basket) or individual (swim) sports. STUDY DESIGN: Cross-sectional study carried out in a convenience sample of athletes. METHODS: The survey was performed by a self-administered, anonymous questionnaire. RESULTS: The study included 327 athletes, 81.0% male, with an average age of 16 years; 36.7% play football, 31.8% basketball, and 31.5% swim. Smoking prevalence among participants was 16.8%. Basket and soccer players were 3 times more likely to be current smokers (20.1%), particularly those aged 16-18 years (35.9%), compared to swimmers (7.8%; in 16-18 year-old: 11.3%). Moreover, basket and soccer players were 7 times more likely to be smokers and to smoke before the practice session compared to swimmers. CONCLUSION: Smoking prevalence in all athletes was lower than that observed in youths. However, athletes of team sports were three times more likely to smoke than athletes of sprint and resistance sports. The reason is likely to be psychological: these sports, not focusing on the individual physical performance, allow athletes to feel less responsible for successes of their teams. It is essential to ensure a specific alliance for prevention between Health and Sport authorities, such as Federations and sporting societies, in order to develop interventions to inform athletes of team sports about the health and physical risks associated to smoking.

INTRODUCTION: Alcohol is recognized as one of four major risk factors for non-communicable diseases. Exposure to alcoholic beverages during the adolescence has been linked to increased heavier drinking habits: obviously, the age of alcohol initiation resulted an important determinant of alcohol dependence. The aim of this study is to analyze knowledge, attitudes and practices in alcohol habit of adolescent population. METHODS: 943 students from 13 schools (middle and upper secondary schools) of the Bari district were enrolled in the study: in each school one class for each age was randomly selected. The research was carried out by an anonymous, self-administered questionnaire which investigated alcohol consumption, knowledge of alcohol consumption of parents and knowledge of the law regulating alcohol consumption. RESULTS: 34.8% (328) have never consumed alcoholic drinks while 65.2% (615) declare the use of alcohol; the average age of alcohol initiation was 12.2 years. 35.7% (329/921) of mothers and 36.6% (335/915) of fathers drink alcohol only on special occasions. 17.9% (168/939) considered that alcohol could be free sale at all while 16.4% (154/939) reported that sale is forbidden for children under 14. CONCLUSIONS: The higher prevalence of alcohol habits and the poor knowledge on alcohol law seemed to indicated the need of improving public health efforts in the prevention of alcohol consumption among Italian adolescents.
