Analysing features of home-based workout during COVID-19 pandemic: a systematic review.

OBJECTIVE: Since the beginning of the COVID-19 pandemic, a decrease in physical activity (PA) related to home confinement has been reported worldwide. However, some individuals were able to engage in physical activities at home. Thus, in a perspective of public health, it may be useful to analyse the available evidence regarding PA adopted during home restrictions, in order to identify possible strategies to help people stay active even during emergency situations. The aim of this review was to analyse how healthy individuals spontaneously exercised at home in the course of the pandemic, in order to detect possible factors associated with this behaviour. STUDY DESIGN: A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. METHODS: The protocol was registered in PROSPERO, an international prospective register of systematic reviews, with the registration number CRD42023394673. A literature search was conducted in PubMed, Scopus, and Web of Science. Cross-sectional studies published in English from the inception of each database to February 06th 2023 and focused on healthy individuals practicing spontaneous PA/exercise at home during the pandemic were considered eligible. The quality assessment was performed using the adapted Newcastle-Ottawa Quality Assessment Scale. Bibliographic information, sample size, study paricipant/population with age, gender, ethnicity, socioeconomic status, education, smart workers or not, anthropometric parameters, characteristics of at home exercises, athletic status and sedentariness, associated health-related effects, and main findings were synthetised. RESULTS: From 504 articles, 19 were included. Notwithstanding the differences in the studies examined, the majority of them reported that previous PA level was associated with exercise in such challenging conditions. Furthermore, technologies aimed at supporting exercise were shown to be a useful resource. CONCLUSIONS: Being habitually active and using digital supports may be associated with a positive attitude towards exercise at home during isolation. This suggests that in emergency situations, exercise should be promoted, also through digital media, especially among those groups who are usually less engaged in PA. Further analyses of longitudinal studies are needed to confirm these findings.

Active breaks: a strategy to counteract sedentary behaviors for Health Promoting Schools. A discussion on their implementation in Italy.

Abstract: School Active Breaks are short bouts of physical activity (5-15 minutes) conducted by appropriately trained teachers and delivered during or between curricular lessons. They are a good strategy to counteract sedentary behaviors, and a growing body of evidence shows that they can represent also a tool to promote and improve health, school wellbeing and academic achievements. On 19 February 2022, the Working Group on Movement Sciences for Health of the Italian Society of Hygiene, Preventive Medicine and Public Health organized an Awareness Day on the effectiveness, usefulness and feasibility of School Active Breaks, opened to teachers, educators, school leaders, pediatricians, personnel from Departments of Prevention and Public Health and Health Policy-makers. During the event, the testimonies about the experiences already carried out in Italy showed that School Active Breaks are an effective intervention that each school can easily include in its educational offer and apply in any context.

Health risks for body pierced community: a systematic review.

OBJECTIVE: Body piercing is defined as the penetration of jewellery into openings made in different body areas. In the last decades, it has become increasingly common in the general population. The aim is to analyse the available literature about complications from body piercing for contributing to raise the awareness towards this issue and to plan and perform appropriate prevention interventions. STUDY DESIGN: This is a systematic review. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used to perform this systematic review; the protocol was registered with PROSPERO [CRD42020177972]. PubMed, Scopus and Web of Science were searched from database inception to April 2020, and articles in English language reporting a proven association between piercings and health risks were included, and their quality were assessed by adequate quality assessment tools. RESULTS: A total of 4748 studies were found, and after duplicates removal and screening, 84 articles were included. Studies dealing with microbiological effects reported these complications both locally and at distant sites as a result of the spreading of the primary site infection: mastitis, endocarditis, glomerulonephritis, cephalic tetanus, viral hepatitis, HIV, cerebellar brain abscess and toxic shock syndrome. In addition, bleeding, gingival recession, dental injuries, contact dermatitis, granulomatous dermatitis, keloid, fibroma and basal cell carcinoma were reported. CONCLUSIONS: Health authorities should promote educational campaigns to spread the knowledge on health risks related to piercings. Besides, piercers are often not adequately aware of all the possible adverse effects due to piercings because their professional training differs among countries. It is therefore advisable to provide periodical upgrade of their education in this field.

Are nutrition and physical activity associated with gut microbiota? A pilot study on a sample of healthy young adults.

BACKGROUND: The literature shows that gut microbiota composition is related with health, and a lot of individual and outer factors may determine its variability. In particular, nutrition and exercise seem to influence the presence in the gut of the two major bacterial phyla of Firmicutes and Bacteroidetes. STUDY DESIGN: An ongoing cross-sectional investigation is aimed to explore these associations in humans. METHODS: Healthy Caucasian young adults were asked to provide a fecal sample in order to analyze their gut microbiome considering their Body Mass Index (BMI), adherence to Mediterranean diet and Physical Activity (PA) level. RESULTS: A total of 59 participants (49.1% males, mean age 23.1 ± 3.14 years) were enrolled so far. Firmicutes (61.6±14.6) and Bacteroidetes (30.7 ± 13.3) showed the highest relative abundance in fecal samples. The Pearson's analysis showed a significant negative correlation between PA and Firmicutes (r =-0.270, p = 0.03). Linear regression confirmed a significant decrease of this phylum with the increase of PA (R2 = 0.07, p = 0.03). CONCLUSIONS: These preliminary results suggest the association between physical activity and gut microbiota composition in healthy humans.

Swimming Pool safety and prevention at the time of Covid-19: a consensus document from GSMS-SItI.

Public health measures to cope with the Covid-19 pandemic, imposed also a shutdown of sports facilities and swimming pools. Safety issues related to recreational waters were emerging during the lockdown, rising concerns on how and when reopening pools and on how improve their management while SARS-CoV-2 is circulating in the population. The GSMS-SItI, Working Group on Movement Sciences for Health of the Italian Society of Hygiene Preventive Medicine and Public Health, discussed and summarized some indications for a suitable preventive approach. Several measures are highlighted, including social distancing, optimized water management, airflow and microclimatic parameters in the pool as well in the annexed rooms, verification of sanitation procedures. The GSMS-SItI underlines that prevention should be based on monitoring of the local epidemiological situation and on the constant collaboration with the local health authority and the national health service.

Peer Education strategies for promoting prevention of doping in different populations.

BACKGROUND: In the field of doping prevention, alongside the traditional functions of repression and control of the phenomenon, educational aspects are becoming increasingly important. Article 18 of the World Anti doping Code obliges the signatories to invest in anti-doping education with the aim of preserving the spirit of sport. The educational commitment should involve young people in health promotion interventions for the prevention of risk behaviors. Therefore, our attention has focused on finding the mechanisms that lead people to make certain behavioral choices. MATERIAL AND METHODS: In the context of preventive programs, to counter the doping phenomenon through health promotion programs, the most recognized method is peer education, particularly with adolescents. It is an educational method according to which some members of a group are empowered and trained to carry out specific activities with their peers. It is constituted as an example of equal relationship and finds its basis in cooperation and solidarity with the aim of increasing empowerment and a healthy development of the identity and collective dimension in young people. RESULTS: Numerous experts - biologists / nutritionists, hygienists, sports coaches, psychologists, teachers of physical education in secondary schools and other stakeholders have actively participated in the co-construction of a training package aimed at activating cascade training processes on the knowledge and skills of peer education in contexts of youth aggregation, such as schools, gyms, sports associations, social gatherings of all kinds. The path allowed to define a peer education model capable of enabling the participants to activate health promotion interventions for the prevention of doping risk behaviors, each in their own setting. CONCLUSIONS: In conclusion, we can say that prevention programs are the more effective the more they are addressed to young people and adolescents and provide interactive and action-oriented interventions. Successful initiatives aim to emphasize the development of life skills and to influence numerous determinants of behavior, including individual attitudes, knowledge, motivations, interpersonal relationships and social norms. If the aim is to act on the change of behavior, the efforts will be more successful if the content of the intervention will give due consideration to the context in which it applies and the target population, involving it and addressing its specific needs and values.

The prevention of doping and the improper use of drugs and food supplements in sports and physical activities: a survey on the activity of the prevention departments of Italian local health authorities.

INTRODUCTION: Doping is an important public health problem widespread not only among elite athletes, but also among amateur and recreational athletes and the general population. In Italy the introduction of doping prevention within the Essential Levels of Care (LEA) with the DPCM 12/1/2017 represents a crucial step towards the implementation of education and health promotion interventions. In this context, the Departments of Prevention (DP) of the Local Health Authorities (LHA) have to play a fundamental role, becoming the cultural and operational reference on this issue. As part of the "Doping prevention: development of a permanent educational tool coordinated by the National Health Service Prevention Departments" project, funded by the Italian Ministry of Health, a survey was conducted on the activities carried out by the DP regarding doping prevention and improper use and abuse of drugs and food supplements in sports and physical activities, as a basis for the harmonization of organizational structures and prevention programs and the creation of a collaboration network at a regional and national level. METHODS: A semi-structured questionnaire consisting of 11 questions, prepared on an electronic platform, was sent to the DP of all the Italian LHA. RESULTS: A total of 38 DP out of 131 (29%) completed the questionnaire, with representation from all regions. 42.1% of DP carried out or are still running programs for the prevention of doping, a percentage that decreases to 27% considering the programs for the prevention of misuse and abuse of drugs and food supplements in sports and in physical activities; in less than half of the DP, 37.5% and 41.7%, respectively, dedicated funds have been allocated. The professionals most involved in prevention of doping are the Specialists in Sport Medicine (81.3%) followed by Specialists in Hygiene (43.8%) and Psychologists (37.5%), while Health Care Assistants (50%) are the professionals most involved in the prevention of the improper use of drugs and food supplements, followed by Specialists in Hygiene and Specialists in Sport Medicine (40%). Most of the DP (71.9%) believe that the introduction of programs to prevent and counteract doping in the LEA will have repercussions on their approach against doping. CONCLUSIONS: The survey, although conducted on a limited sample, has provided an important framework relating to programs for the prevention of doping and the misuse and abuse of drugs and food supplements in sports and in the physical activities carried out by DP. A remarkable heterogeneity has been highlighted, both at national and regional level. It is urgent to provide DP with homogeneous and effective organizational models and adequate operational tools, paying particular attention to the training of all the professionals involved. It is also essential to implement permanent monitoring tools.

Exploring the association between physical activity and gut microbiota composition: a review of current evidence.

The gut microbiota is implicated in digestive, metabolic and immune processes of the host. The physiological and pathophysiological functions of the intestinal microbiota depend of its composition, and several individual or external factors may be associated with the presence of some categories, phyla or species of microorganisms in the gut. In particular, two bacterial phyla - Firmicutes and Bacteroidetes - are predominant in the human gut and their relative concentrations seem to be related with age, gender, diet habits and weight status. In the last decade, several studies have tried to characterize the possible role of physical activity in determining qualitative and quantitative composition of the intestinal microbiota. This review is aimed at exploring the current evidences regarding the association between physical activity and gut microbiota composition in animal models and in the humans. Further studies are needed to clarify the mutual relationships among exercise, diet, nutritional supplements/doping agents and gut microbiota.

Higher education on physical activity and sport: The Movement Sciences graduate as a resource to promote healthy lifestyles in the National Health System.

Currently, physical activity is an important tool that may be useful to improve people health and quality of life through sustainable and effective interventions. In order to obtain durable improvements of individuals' behaviors, however, consistent changes in services organization and the creation of new opportunities in life settings are needed. This requires necessarily the involvement of complementary figures with specific competences. Considering their peculiar training curriculum, Movement Sciences graduates represent key figures in this context and they can operate fully in interventions of health education and promotion, within multidisciplinary teams collaborating with the National Health System (NHS), in order to obtain the global undertaking of citizens.

Hospital environment as a reservoir for cross transmission: cleaning and disinfection procedures.

BACKGROUND: Healthcare associated infections (HAIs) represent a serious problem for public health, as they increase the morbidity and mortality rates, present a relevant financial burden, and significantly contribute to the antimicrobial resistance. METHODS: The aim of this review was to investigate the literature about HAIs, with particular reference to hospital environments and the role of cleaning and disinfection procedures. Hospital environments are an essential reservoir for HAIs cross transmission, and the application of appropriate procedures related to hand hygiene and disinfection/sterilization of surfaces and instruments remain key strategies for controlling HAIs. RESULTS: Different procedures, based on the risk associated with the healthcare procedure, are recommended for hand hygiene: washing with soap and water, antiseptic rubbing with alcohol-based disinfectants, antiseptic and surgical hand washing. Environmental surfaces can be treated with different products, and the mostly used are chlorine-based and polyphenolic disinfectant. The reprocessing of instruments is related to their use according to the Spaulding's classification. In addition, scientific evidence demonstrated the great relevance of the "bundles" (small set of practices performed together) in controlling HAIs. CONCLUSIONS: Research agenda should include the improvement of well-known effective preventive procedures and the development of new bundles devoted to high-risk procedures and specific microorganisms.

Potential antimicrobial effects of photocatalytic nanothecnologies in hospital settings.

BACKGROUND: Recently, several advanced technologies have been considered to reduce the microbial load in hospital environments and control Healthcare Associated Infections (HAIs) incidence. New strategies for preventing HAIs have continuously evolved, including enforcement of hygiene procedures by novel liquid biocides or no-touch technologies, self-disinfecting surfaces coated by heavy metals or light-activated photosensitizers such as Titanium Dioxide (TiO2) nanoparticles. STUDY DESIGN: Review publications concerning the use of photocatalytic systems in hospital setting, focusing on products based on TiO2. METHODS: Specific keywords combinations were analitically searched in PubMed and Scopus databases. RESULTS: Starting 80s-90s, over 2000 papers report "in vitro" studies on antimicrobial activity of TiO2 photocatalysis on several microorganisms including bacteria, viruses, fungi, yeasts, and antibiotic resistant strains. Besides, at least 4 selected papers addressed the potentials of this approach by "in field" studies, showing a widespread pool of applications in hospital and healthcare settings. However, the low number of available experiences and their heterogeneity represent major limitations to achieve a comprehensive final overview on effectiveness and feasibility of these technologies. CONCLUSIONS: Photocatalytic systems based on TiO2 represent a promising strategy for hospital hygiene and HAI prevention. Additional "in field" studies are desirable in a next future to further evaluate and exploit this novel and interesting health technology.

Procedures in endoscope reprocessing and monitoring: an Italian survey.

BACKGROUND: The high diffusion of endoscopes worldwide and the need for effective reprocessing methods requested the development of guidelines and implementation of surveillance procedures at local level. STUDY DESIGN: In order to collect data on everyday's practice and adherence to available guidelines, endoscopy units from different public institutions were surveyed using a dedicated questionnaire. METHODS: Between July and November 2015 a survey was carried in 12 main hospitals from 10 different Italian regions, involving 22 endoscopy units. The state of the art of national and international guidelines was investigated to compare the protocols adopted at local level. RESULTS: In all the surveyed hospitals, the reprocessing activity is based on pre-established protocols in adherence with principal guidelines. Enzymatic detergents, which are recommended by the international guidelines, are used in 55.6% of units and peracetic acid is currently the most widely used chemical disinfectant. Discrepancies were observed in the application of periodic quality controls. CONCLUSION: Updated guidelines are generally applied in reprocessing practice. Quality controls may represent a critical issue to improve effectiveness and surveillance. The whole of acquired data can promote a positive trend towards the application of best practices.

Monitoring biodiversity in libraries: a pilot study and perspectives for indoor air quality.

Indoor Air Quality (IAQ) in libraries is influenced by the presence of specific factors which can impact on both paper storage as well as people health. Microclimatic conditions induce and support a biodiversity pattern involving environmental and anthropic microorganisms. We used a multidisciplinary monitoring model to characterize microflora biodiversity by Next Generation Sequencing (NGS). Biodiversity indexes were adapted to evaluate anthropic vs environmental pollution by combining Shannon mean index (H), species representativeness (EH), human/environmental pollution ratio (SA) to better characterize the NGS output and acquire synthetic information on Indoor Air Microbial Biodiversity (IAMB). Results indicate a frequently low microbial load (IGCM/m3 < 1000) characterized by different species (n = 102), including several cellulose metabolizing bacteria. Workers and visitors appeared a relevant source of microbial contamination. Air biodiversity assayed by NGS seems a promising marker for studying IAQ.

Exposure to individual and multiple carcinogenic metals during paediatric age: an experience from an Italian urban scenario.

BACKGROUND: Exposure to single and multiple carcinogenic metals and/or semimetals represents a major environmental risk factor for public health. In particular, children are more susceptible to environmental pollutants than adults, but specific studies are still limited. The aims of the present study were: 1) to trace the exposure and co-exposure profiles to eight known or suspected carcinogenic metals and semimetals (As, Be, Cd, Co, Cr, Ni, Pb, and Sb); and: 2) to evaluate the influence of some possible interfering/confounding factors on the exposure to these elements during childhood. STUDY DESIGN: Cross-sectional study. METHODS: We recruited 159 healthy Italian children attending a primary school of the urban area of Rome, Italy. Selected metals were determined by inductively coupled plasma mass spectrometry on urinary samples collected at the end of a "typical" day (one sample for each child), while information about possible confounding/interfering factors were collected via questionnaires. RESULTS: The great part of the studied children resulted co-exposed to the monitored metals: 83.2%, 69.2%, 51.0% and 29.3% of the participants were concurrently exposed to at least two, three, four and five trace elements, respectively. Gender was the only one among the investigated variable that significantly influenced the co-exposure, with females resulting at lower risk (OR = 0.392; 95 IC = 0.156 - 0.989; p < 0.047). CONCLUSIONS: Given the importance of protecting child's health and the risks related to the exposure to carcinogenic metals, especially when they occur simultaneously, other researches in this field are strongly recommended.

Development of the laboratory prototype "CavyPool" for assessing treatments and materials for swimming pools.

BACKGROUND: Hygiene and surveillance in swimming pools are established by WHO Guidelines and national laws. Progress in water management and pool construction is revolutionizing the field, introducing new materials, systems, disinfection procedures or monitoring markers. Innovation advances challenge the upgrading of safety and quality in pools and the appropriate implementation of guidelines. STUDY DESIGN: In order to provide a device for laboratory test, a prototype was realized and applied to study and compare swimming pool materials and treatments. METHODS: A pool scale-model was engineered and evaluated by computational fluid dynamics algorithms. An automated real time monitoring assured steady state. Critical control points along the water circuit were made accessible to allow the placing of different biocides or water sampling. Simulations were safely performed in a standard hood. Materials for pool surfaces and pipelines were evaluated for biofilm formation under different disinfection conditions. Adherent microorganisms were assayed by mfDNA analysis using real time PCR. RESULTS: The prototype reached the steady state within 5-25 hours under different conditions, showing chemical, physical and fluid-dynamic stability. A method was optimized for testing materials showing their different response to biofilm induction. Several innovative PVC samples displayed highest resistance to bacterial adhesion. CONCLUSIONS: A device and method was developed for testing swimming pool hygienic parameters in laboratory. It allowed to test materials for pools hygiene and maintenance, including biofilm formation. It can be applied to simulate contaminations under different water treatments or disinfection strategies. It may support technical decisions and help policymakers in acquiring evidences for comparing or validating innovative solutions.

The role of the hygienist in prevention and health promotion through physical activity: the contribute of the Working Group "Movement Sciences for Health" of the Italian Society of Hygiene.

Inactivity is the fourth leading risk factor for chronic diseases morbidity and mortality, with high related costs. Exercise represents a useful instrument of preventive medicine due to its effects in maintaining and improving psycho-physical wellbeing at any age and condition. The promotion of physical activity may represent an important prevention strategy for public health, and it implies an interaction among several figures from health and wellbeing settings. Due to their competencies in prevention and health promotion, hygienists play a fundamental role as intermediary among the different actors involved in this multidisciplinary scenario. The Working Group "Movement Sciences for Health" of the Italian Society of Hygiene, established in 2009, is engaged in detailing, evaluating and strengthening the role of physical activity for health promotion. It combines rigorous research activities regarding human movement for health with their application in public health setting and with the evaluation of their sustainability. Its attention is also focused on the safety aspects related to structural conditions of sport facilities and to health conditions or behaviours of their users as well. These activities led to numerous scientific publications and training events.

The environmental biological signature: NGS profiling for forensic comparison of soils.

The identification of the source of a specific soil sample is a crucial step in forensic investigations. Rapid advances in next generation sequencing (NGS) technology and the strong reduction of the cost of sequencing have recently opened new perspectives. In the present work a metabarcoding approach has been successfully applied to forensic and environmental soil samples, allowing the accurate and sensitive analysis of microflora (mfDNA), plants, metazoa, and protozoa DNA. The identification of the biological component by DNA metabarcoding is a strong element for the discrimination of samples geologically very similar but coming for distinct environments.

[Comparison of cultural methods for the recovery of Pseudomonas aeruginosa: the UNI EN ISO 16266 reference method and the alternative method Pseudalert®]. / Confronto di metodi colturali per il rilevamento di Pseudomonas aeruginosa: il metodo di riferimento UNI EN ISO 16266 e il metodo alternativo Pseudalert®.

BACKGROUND: For the water analysis, for Pseudomonas aeruginosa a presumptive positive result can be achieved in 40- 48 hours using the traditional membrane filtration technique followed by an additional 24-48 hour confirmation stage. Conversely, the Pseudalert Quanti-Tray™ method can give confirmed results after 24-28 hours. In this case, actively growing strains of Pseudomonas aeruginosa show a confirmed positive result when a specific enzyme cleaving the substrate in the reagent produces a blue fluorescence under 365 nm ultraviolet light. A comparison of the performance of the Pseudalert respect to the standard method was conducted using statistical methods. METHODS: Drinking water was analyzed in parallel with the membrane filtration technique using Pseudomonas CN agar (UNI EN ISO 16266) and the Pseudalert. Confirmation test are requested by the standard method and although Pseudalert Quanti-Tray™ gives confirmed results, all the positive isolates were also confirmed. Data were analyzed by statistical methods. RESULTS: For drinking water, Pseudalert showed a very high sensitivity (98,8%) and a high percentage of specificity (96,8%). From a total of 889 positive isolates, a very high confirmation rates (99,3%) was calculated. Statistical analyses confirmed that the two methods were not statistically different. CONCLUSIONS: These results indicate that the Pseudalert produces confirmed results in a shorter time than the standard reference method allowing the detection of Pseudomonas aeruginosa with no further confirmation steps. It could be a valid alternative method for the water analysis.

The SNPs in the human genetic blueprint era.

The analysis of human genetic variability can lead to the comprehension of medical issues and to the development of personalized therapeutic protocols. Single nucleotide polymorphisms, are the most common type of human genetic variation and have been associated to disease development and phenotype forecasting. The recent technologies for DNA sequencing and bioinformatic analysis are now giving the opportunity to develop new diagnostic and prevention approaches also through health promotion protocols. The genetic data management is at the same time underlining technical limitations and old ethical issues.

Molecular enrichment for detection of S. aureus in recreational waters.

The identification of rapid methods for the control of recreational water and of aquatic environments with similar characteristics is necessary to provide adequate levels of health safety for users. Molecular techniques have been proposed in recent years as a viable alternative to traditional microbiological methods, as they offer various advantages and are less time consuming than traditional tests. An innovative protocol based on molecular enrichment that allows the identification of low concentrations of Staphylococcus aureus in recreational water has been developed. The method is based on the specific amplification of prokaryotic genomic DNA by the usage of universal primers for 23S rDNA; subsequently, a second amplification step is performed with specific real-time polymerase chain reaction (PCR) primers and probe. This approach shows sensitivity levels similar to those observed with microbiological tests, with the additional benefits of the specificity typical of nucleic acids techniques. This methodology is easily applicable also to other microbiological parameters, representing an important milestone in hygiene monitoring by the detection of specific pollution indicators.
