Background. Causing approximately 8 million deaths each year, tobacco smoking represents a significant public health concern. Evidence shows that smoking significantly impairs antibody production and immune cell activity following vaccination. Objectives. This review aims to provide a comprehensive overview of the literature regarding how smoking reduces the effectiveness of active immunization by affecting vaccine-induced immune response. Methods. This study was performed according to the PRISMA guidelines, and the protocol was registered on the PROSPERO platform (ID: CRD42024582638). PubMed, Scopus and Web of Science were consulted as bibliographic and citation databases. Studies published in Italian and English and that aimed to investigate the effects of exposure to active and passive tobacco smoking on vaccine-induced immune response were included. Results. Thirty-four studies were selected. Overall, a decrease in antibody levels and avidity and in immune cell production were observed in individuals exposed to smoke. The meta-analysis showed a weighted mean difference between smokers and non-smokers equal to 0.65 (95% CI: 0.10–1.19, p = 0.02) for vaccinations against COVID-19, influenza, pneumococcus, HBV, HPV, tetanus, pertussis, polio, haemophilus influenzae type b, measles–mumps–rubella, and recurrent urinary tract infections. Conclusions. Smoking cessation campaigns should be considered in order to increase the effectiveness of vaccination programs. Furthermore, the opportunity to adopt different vaccine dosing schemes for smokers and non-smokers, especially in acute epidemics, should be considered. [ABSTRACT FROM AUTHOR]

Background: Many human activities release harmful substances, contaminating the air, water, and soil. Since exposure to environmental pollutants is currently unavoidable, it is important to verify how these compounds may influence individual immune responses to vaccines. Methods: This review was conducted in accordance with the PRISMA statement. The protocol was registered on the PROSPERO platform with the following ID: CRD42024582592. We evaluated all observational, semi-experimental, and experimental studies written in both Italian and English that reported possible effects of exposure to environmental pollutants on the production of vaccine-induced antibodies. Results: Forty-two studies were included. The effects of pollutants were examined mainly in terms of antibody production in relation to mumps, measles and rubella, diphtheria and tetanus, hepatitis A and B, Haemophilus influenzae type B, influenza, tuberculosis, pertussis, Japanese encephalitis, poliomyelitis, and COVID-19 vaccines. Perfluorinated compounds were the most studied pollutants. Conclusions: Correlations between exposure to pollutants and reductions in antibody production were found in quite all the selected studies, suggesting that pollution control policies could contribute to increase the efficacy of vaccination campaigns. However, the heterogeneity of the examined studies did not allow us to perform a meta-analysis, and the literature on each type of vaccine or pollutant is still too limited to generate robust evidence. In order to confirm the findings of the present systematic review, and in the perspective of establishing possible exposure limit values for each type of pollutant, further research in this field is required.

AbstractThis cross-sectional study was aimed to investigate knowledge, attitudes, and practices regarding dietary supplements (DS) and nutraceuticals among athletes, gym practitioners, and individuals who did not exercise regularly. A total of 372 participants, aged 18–65, completed a questionnaire covering demographics, supplement usage, and three validated tools: the Knowledge about Dietary Supplements (KaDS), Supplements Knowledge Score (SKS), and Knowledge, Attitude, and Practice towards Nutraceuticals (KAPN). Significant differences were found in the use of vitaminised water, protein powder, glucosamines, beetroot juice, creatine, omega-3, and pre-workout supplements among the groups, with gym practitioners reporting the highest usage. Athletes scored the highest in knowledge of DS effects on health, while both athletes and gym practitioners scored higher than non-exercisers in knowledge related to sports supplements. However, all groups showed inadequate knowledge of nutraceuticals, and moderately positive attitudes towards these products. Older participants performed better in knowledge questionnaires. These findings suggest that gym practitioners, inactive and young people could benefit most from educational interventions regarding dietary supplementation. [ABSTRACT FROM AUTHOR]

Background: Scientific evidence demonstrates that poor sleep quality can lead to various health problems. This study aimed to investigate sleep patterns among Italian university students and identify several factors that may contribute to its quality., Study Design: Cross-sectional study., Methods: An electronic questionnaire regarding sociodemographic characteristics, lifestyle, and sleep-related habits, including the Pittsburgh Sleep Quality Index (PSQI) questionnaire, was distributed between January 2022 and July 2023 among students belonging to 12 universities located in Northern, Central, and Southern Italy., Results: On a total of 1,674 questionnaires collected, the participants (mean age 24.06±4.56 years, 71.3% F) reported an average number of hours of nocturnal sleep equal to 6.89±1.28 hours. A total of 927 (54.6%) of respondents showed a poor sleep quality (PSQI >5). Regression analysis showed that better sleep quality is associated with lower age, attending universities in Northern Italy, less time spent on electronic devices during the day, not being used to study at night and not playing videogames before sleep., Conclusion: From a public health perspective, our findings suggest that public health operators should raise the awareness of young adults about the importance of sleep quality for maintaining good health, as well as the impact that certain behaviors can have on sleep.

Purpose: This scoping review aims to evaluate the impact of physical activity interventions on the well-being of incarcerated individuals. It seeks to provide a comprehensive overview of existing research on various forms of physical activity, including structured exercise programs, yoga and mindfulness, and their effects on both mental and physical health within prison populations., Design/methodology/approach: A scoping review was conducted by searching Google Scholar, PubMed and Web of Science in June 2024. Keywords used included "physical activity," "exercise," "fitness," "sports," "prisoners," "inmates," "incarcerated individuals," "well-being," "mental health," "physical health," "psychological well-being" and "emotional well-being." After screening 1,736 potential articles, 54 relevant studies were selected. These included structured exercise programs, yoga/mindfulness programs and evaluations of physical activity levels. Two authors independently reviewed and selected studies based on predefined inclusion criteria, ensuring a comprehensive overview of the literature on physical activity interventions in prison settings., Findings: The review identified 12 relevant studies, revealing that physical activity interventions, including structured exercise programs, yoga and mindfulness, positively impact the psychological and physical well-being of incarcerated individuals. Consistent improvements were noted in mental health outcomes, such as reduced depression and anxiety, and enhanced physical health indicators, including lower body mass index and increased fitness levels. The findings underscore the necessity for age- and gender-specific interventions to address the unique health challenges faced by different inmate demographics, highlighting the importance of incorporating diverse and culturally relevant exercise programs in prisons., Originality/value: This review uniquely synthesizes the impact of various physical activity interventions on the well-being of incarcerated individuals, emphasizing the necessity for tailored, culturally relevant programs. Notably, no previous review has comprehensively analyzed this aspect. By comparing diverse types of interventions, it provides comprehensive insights into the benefits of structured exercise, yoga and mindfulness in prison settings. This work highlights the importance of implementing physical activity in various forms, especially for female inmates, to enhance health and well-being. It offers valuable guidance for developing effective rehabilitation strategies in correctional facilities., (© Fabrizio Liguori and Patrizia Calella.)
