Objectives: The authors aim to show the possibility of stigma that hits affected Mpox patients because of the statements of society involving their sexual sphere., Introduction: 23 July 2022, the Director-General of the WHO, Thedos Ghebreyesus, issued an international public health alert regarding cases of Mpox (formerly known as Monkeypox). Although Mpox has been present in an endemic form for years in some Central African countries, the spread of the disease outside Africa has aroused considerable alarm in populations already sorely afflicted by the COVID-19 pandemic. Aside from the data, what is striking is that Mpox, like other infectious diseases, seems to have become a problem only when it began to cross the borders of Africa. Some may justify this attitude simply by ascribing it to the fear of an epidemic outside the areas where the virus is endemic. However, in such cases, and especially after the COVID-19 experience, other factors are also involved: lack of information and, even more so, the human capacity to utilise diseases to reinforce arguments against the tendencies, inclinations, orientations and behaviours of some social groups. Such information, albeit basically correct, is nevertheless incomplete. Moreover, it tends to prompt a view of this disease that may give rise to highly dangerous and embarrassing situations, engendering the risk of repeating the error that was made about AIDS. Mpox is the latest in a series of epidemics that have struck humanity in the space of very few years., Material and Methods: Setting and partecipants: people and social groups who, due to sexual orientations and behaviours, are considered to be at risk of being infected with Mpox. Main outcomes measures: - outcomes directly related to mental health of Mpox patients: anxiety, fear and depression, emotional difficulties, feelings of loneliness and isolation; - well-being outcomes of people with Mpox; - risk of not being able to reduce the epidemic among those groups don't feel as though they belong to LGBTQ and therefore do not implement any kind of prevention., Results: Limit the contagion from Mpox through specific health and communication campaigns. Remove any stigma related to Mpox disease., Conclusions: In the face of this disease, it is absolutely essential that we do not needlessly isolate groups of people by feeding stigma, prejudice and discrimination, which can have devastating effects not only on individuals but also on society as a whole. As the full inclusion of persons of LGBTQ community is probably still a long way off, we must surely wonder when we will be ready enough to achieve the important objective of equality for all., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (©2024 Pacini Editore SRL, Pisa, Italy.)

Recent years have seen increasingly severe natural disasters, the consequences of which have been catastrophic. Clearly, our global environment is undergoing major changes. The climate is becoming deranged and pollution on a global scale afflicts air, water, and land. We are faced with an unprecedented shortage of cultivable land and fresh water for drinking, irrigation, and livestock farming, while our marine systems are breaking down. These environmental changes have a very high anthropogenic component; they are induced by human activities that are potentially dangerous for both the environment and human life. Moreover, not only do they have an enormous impact on the environments in which we live and on our way of life, they also have harmful effects on our health. Indeed, we must understand that our body - as Hippocrates explained long ago - is a system that constantly interacts with the surrounding environment., Competing Interests: The authors declare no conflict of interest., (©2024 Pacini Editore SRL, Pisa, Italy.)

Introduction: Lean is largely applied to the health sector and on the healthcare-associated infections (HAI). However, a few results on the improvement of the outcome have been reported in literature. The purpose of this study is to analyze if the lean application can reduce the HAI rate., Methods: A comprehensive search was performed on PubMed/Medline, Scopus, CINAHL, Cochrane, Embase, and Google Scholar databases using various combinations of the following keywords: "lean" and "infection". Inclusion criteria were: 1) research articles with quantitative data and relevant information on lean methodology and its impact on healthcare infections; 2) prospective studies. The risk of bias and the study quality was independently assessed by two researchers using the "The National Institutes of Health (NIH) quality assessment tool for before-after (Pre-Post) study with no control group". The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines has been used. 22 studies were included in the present meta-analysis., Results: Lean application demonstrated a significant protective role on healthcare-associated infections rate (RR 0.50; 95% C.I.: 0.38-0.66) with significant impact on central line-associated bloodstream infections (CLABSIs) (RR 0.47; 95% C.I.: 0.28-0.82)., Conclusions: Lean has a positive impact on the decreasing of HAIs and on the improvement of compliance and satisfaction of the staff., (©2022 Pacini Editore SRL, Pisa, Italy.)

Introduction: We described an outbreak of C. difficile that occurred in the Internal Medicine department of an Italian hospital and assessed the efficacy of the measures adopted to manage the outbreak., Methods: The outbreak involved 15 patients and was identified by means of continuous integrated microbiological surveillance, starting with laboratory data (alert organism surveillance). Diarrheal fecal samples from patients with suspected infection by C. difficile underwent rapid membrane immuno-enzymatic testing, which detects both the presence of the glutamate dehydrogenase antigen and the presence of the A and B toxins. Extensive microbiological sampling was carried out both before and after sanitation of the environment, in order to assess the efficacy of the sanitation procedure., Results: The outbreak lasted one and a half month, during which time the Committee for the Prevention of Hospital Infections ordered the implementation of multiple interventions, which enabled the outbreak to be controlled and the occurrence of new cases to be progressively prevented. The strategies adopted mainly involved patient isolation, reinforcement of proper hand hygiene techniques, antimicrobial stewardship and environmental decontamination by means of chlorine-based products. Moreover, the multifaceted management of the outbreak involved numerous sessions of instruction/training for nursing staff and socio-sanitary operatives during the outbreak. Sampling of environmental surfaces enabled two sites contaminated by C. difficile to be identified., Conclusions: Joint planning of multiple infection control practices, together with effective communication and collaboration between the Hospital Infections Committee and the ward involved proved to be successful in controlling the outbreak.

Objective: To describe the occurrence of CRKP infections in a tertiary care hospital and to analyse the allelic profiles of the clinical strains involved and the most frequent carbapenemases., Design: The study analyzed cases of infection due to CRKP in the period 2013-2014; 147 cases were recorded, most of which (82.31%) were in-hospital infections., Setting: A hospital in northern Italy., Methods: We retrospectively collected: data on patient characteristics and the microbiological characteristics of CRKP. Isolates from 72 of the in-hospital cases underwent molecular typing (MLST); in addition, in each isolate, a procedure for the detection of the blaKPC gene was carried out., Results: The in-hospital death rate was 24.0% in 2013 and 37.5% in 2014. However, the difference between these two values did not prove statistically significant (P > .05). Analysis of mortality revealed that bloodstream infections were more frequently associated with death than other infections (χ 2 = 14.57, P < .001). The age-adjusted Cox proportional hazard model revealed that the patients with bacteremia due to CRKP had a 3-fold higher risk of death (HR 3.11; 95% CI 1.66 - 5.84, P< .001) than those with infections of other sites. MLST revealed that the prevalent allelic profile was ST 512 (79.62%); the most frequent carbapenemase was KPC-3 (83.8%)., Conclusions: Our results are in line with those of recent studies, which have shown that the spread of CRKP in Italy is a matter of concern and that further efforts have to be made to prevent the potential dissemination of carbapenemase-producing clones of K. pneumoniae, whenever possible.

Background: The rate of surgical site infections (SSI) is strongly influenced by operating room quality, which is determined by the structural features of the facility and its systems and by the management and behavior of healthcare workers. The aim of the present study was to assess microbial contamination in the operating room during hip- and knee-replacement procedures, the behavior of operating room staff and the incidence of SSI through postdischarge surveillance., Methods: Microbial contamination was evaluated by active and passive sampling at rest and in operating conditions. Organizational and behavioral characteristics were collected through observational assessment. The incidence of SSI was evaluated in 255 patients, and follow-up examinations were carried out 30 and 365 days after the procedure., Results: The mean values of the airborne and sedimenting microbial loads were 12.90 CFU/m 3 and 0.02 CFU/cm2/h, respectively. With regard to outcome, the infection rate proved to be 0.89% and was associated with knee-replacement procedures. The microorganism responsible for this superficial infection was Staphylococcus aureus., Conclusions: Clinical outcomes proved to be satisfactory, owing to the limited microbial load (in both at-rest and operating conditions), the appropriate behavior of the staff, compliance with the guidelines on preoperative antibiotic prophylaxis, and efficient management of the ventilation system.

Glycopeptide resistance in Staphylococcus aureus is a source of great concern because, especially in hospitals, this class of antibiotics, particularly vancomycin, is one of the main resources for combating infections caused by methicillin-resistant Staphylococcus aureus strains (MRSA). Reduced susceptibility to vancomycin (VISA) was first described in 1996 in Japan; since then, a phenotype with heterogeneous resistance to vancomycin (h-VISA) has emerged. H-VISA isolates are characterised by the presence of a resistant subpopulation, typically at a rate of 1 in 10(5) organisms, which constitutes the intermediate stage betweenfully vancomycin-susceptible S. aureus (VSSA) and VISA isolates. As VISA phenotypes are almost uniformly cross-resistant to teicoplanin, they are also called Glycopeptides-intermediate Staphylococcus aureus strains (GISA) and, in the case of heterogeneous resistance to glycopeptides, h-GISA. The overall prevalence of h-VISA is low, accounting for approximately 1.3% of all MRSA isolates tested. Mortality due to h-GISA infections is very high (about 70%), especially among patients hospitalised in high-risk departments, such as intensive care units (ICU). Given the great clinical relevance of strains that are heteroresistant to glycopeptides and the possible negative impact on treatment choices, it is important to draw up and implement infection control practices, including surveillance, the appropriate use of isolation precautions, staff training, hand hygiene, environmental cleansing and good antibiotic stewardship.

Surgical site infections (SSI) account for 14% to 17% of all hospital-acquired infections and 38% of nosocomial infections in surgical patients. SSI remain a substantial cause of morbidity and death, possibly because of the larger numbers of elderly surgical patients or those with a variety of chronic and immunocompromising conditions, and emergence of antibiotic-resistant microorganisms. Factors causing surgical site infection are multifarious. Several studies have identified the main patient-related (endogenous risk factors) and procedure-related (external risk factors) factors that influence the risk of SSI. The rate of surgical wound infections is strongly influenced by operating theatre quality, too. A safe and salubrious operating theatre is an environment in which all sources of pollution and any micro-environmental alterations are kept strictly under control. This can be achieved only through careful planning, maintenance and periodic checks, as well as proper ongoing training for staff Many international scientific societies have produced guidelines regarding the environmental features of operating theatres (positive pressure, exchanges of filtered air per hour, air-conditioning systems with HEPA filters, etc.) and issued recommendations on healthcare-associated infection, including SSI, concerning surveillance methods, intervention to actively prevent SSI and approaches to monitoring the implementation of such strategies. Therefore, the prevention of SSI requires a multidisciplinary approach and the commitment of all concerned, including that of those who are responsible for the design, layout and functioning of operating theatres.

An experimental study was conducted in a hospital in Liguria (northern Italy) on two groups of patients with the same disease severity who were undergoing the same type of surgery (primary hemiarthroplasty). Our aim was to assessing the results of a quality-improvement scheme implemented in the operating room. The quality-improvement protocol involved analyzing a set of parameters concerning the operating team's behavior and environmental conditions that could be attributed to the operating team itself A program of training and sanitary education was carried to rectify any improper behavior of the operating staff Two hundred and six hip-joint replacement operations (primary hip hemiarthroplasty--ICD9-CM 81.51) all conducted in the same operating room were studied: 103 patients, i.e. operations performed before the quality-improvement scheme and 103 patients, i.e. operations performed after the quality improvement scheme; all were comparable in terms of type of surgery and severity. The scheme resulted in an improvement in both behavioral and environmental parameters and an 80% reduction in the level of microbial air contamination (p < 0.001). Patient outcomes improved in terms of average postoperative hospitalization time, the occurrence and duration of fever (> 37.5 degrees C) and microbiological contamination of surgical wounds. From an economic point of view, facility efficiency increased by 28.57%, average hospitalization time decreased (p < 0.001) and a theoretical increase of Euro 1,441,373.58 a year in revenues was achieved.

Introduction: Recent discoveries in cell therapy research present new opportunities for cellular products to be used to treat severe, and as yet incurable, diseases. It is therefore essential to implement a quality control programme in order to ensure that safe cells and tissues are provided., Methods: In a preliminary phase of the setting up of a the cellfactory, monitoring was carried out monthly over a 6-month period in one out of three cell therapy laboratories and filter rooms in order to evaluate the microbial contamination of air and surfaces and the presence of airborne particulates., Results: The mean total bacterial and fungal loads measured in the air in the centre of the filter room were 20.7 +/1 28.9 colony-forming units (cfu)/m3 and 9.2 +/- 15.4 cfu/m3, respectively, and 5.2 +/- 4.1 cfu/m3 and 6.8 +/- 13.4 cfu/m3, respectively, in the laboratory. The mean fungal load values recorded on the surfaces sampled in the laboratory were in 6 out of 18 cases higher than the reference values (5 cfu/plate). As to the results of particulate monitoring, with regard to the 0.5 microm particles, about 83% of the samples revealed values below the limit of 350.000 particles per cubic metre., Conclusions: In this set-up phase, monitoring was able to pick out structural and organisational flaws acceptable in a laboratory compliant with Good Manufacturing Practices class C (Annex 1), but not in a class B facility. Thanks to this preliminary monitoring phase, and by correcting these flaws, the clean room facility could achieve compliance to class B.

Introduction: In dentistry, as in surgery, there is a risk of cross-infection for both patients and staff The aim of this research was to evaluate procedures and behaviors enacted by dental staff which might engender a risk for themselves and their patients., Methods: A questionnaire was administered to 106 dental workers in Genoa (Italy), both public and private. Whenever personal interviews were conducted, the facilities involved were also inspected and the activities of the dental staff were observed directly., Results: This research highlighted some critical points in both structural and organizational features and in the management of infective hazards in the sample considered. In some cases, inadequacies were noted with regard to the prevention of cross-infections, such as the lack of disinfection of work surfaces and the handles of chair-set accessories., Discussion and Conclusions: The particular nature of dental work, in which aerosols of blood and saliva may be produced by rotating instruments, engenders a risk of infection. Application of the various preventive measures available can significantly reduce microbial contamination and the risk of occupational infection and cross-infections. Furthermore, improvement in the structural and organizational features of dental surgeries and the continuing education of health-care workers is indispensable to the control and prevention of infectious diseases.

Introduction: As occupational exposure to anaesthetic gases is one of the main risks for operating theatre staff an environmental monitoring campaign was conducted in order to evaluate the degree of pollution by nitrous oxide (N2O) in the operating theatres of some hospital facilities in Liguria., Methods: Any leaks (systemic and/or managerial) of anaesthetic gas and the number of efficacious air exchanges per hour supplied by air-conditioning systems were evaluated by means of an IR spectrometer, which was wired to a computer for data collection and analysis. The concentration of nitrous oxide in the centre of each operating theatre was measured by means of chemo-adsorbent cartridges analysed by gas chromatography., Results: In 76.0% of the operating theatres examined a mean environmental concentration of N2O below the legal limits was recorded. The highest mean concentrations were generally associated with the presence of systemic leaks. Supplying an adequate number of efficacious air exchanges per hour enabled environmental concentrations of anaesthetic gas to be kept within acceptable levels., Discussion and Conclusions: Training personnel in the correct management of the operating theatre and of anaesthesia equipment, and ensuring the availability of an adequate air-conditioning system enable the risk of exposure to nitrous oxide to be minimised. This can be achieved through a concerted effort on the part of all involved, in accordance with the concept of ongoing improvement in healthcare services.
