Il ruolo del genere nel lavoro con gli uomini autori di violenza: Affetti e rappresentazioni dei professionisti della salute
Il lavoro di contrasto alla violenza maschile contro le donne ha recentemente spostato il proprio focus dalla donna vittima di violenza all’uomo maltrattante. Questo cambio di paradigma ha portato all’implementazione di programmi di trattamento rivolti agli autori di violenza e all’impegno di professionisti uomini nel contrasto alla violenza. Il presente studio ha l’obiettivo di esplorare gli affetti e le rappresentazioni di 7 professionisti della salute (3 uomini e 4 donne) che si occupano di trattare uomini autori di violenza, con un focus specifico sul genere di appartenenza. L’analisi semiotica quali-quantitativa applicata alle interviste semi-strutturate analizzate tramite il software T-LAB ha consentito di individuare la presenza di 5 cluster: 1) Riconoscimento delle emozioni; 2) Posizionamento di genere; 3) Competenze lavorative; 4) Percezione del rapporto tra i generi; e 5) Rapporto con il lavoro. I risultati sembrano confermare che il genere di appartenenza degli operatori giochi un ruolo fondamentale nell’esperienza lavorativa con gli uomini maltrattanti
A novel technology for disinfecting surfaces infested with Candida auris: the UVC chip
Background
The fungal pathogen Candida Auris is increasingly associated with multidrug-resistant infections that are highly expensive for the Health Care System. The spreading of this pathogen can occur, among others, through contact with infected surfaces or medical instruments. This study evaluated the efficacy of a novel UVC chip, novel alternative to UVC LEDs and lamps, in inactivating Candida auris strain.
Methods
This experimental study was carried out between July and September 2020 at the University of Siena. Candida auris (ATCC 12372) at two known concentrations (1.5X107 and 1.5x106 CFU/ml) at a fixed distance (7,5 cm) from the chip (5.1mW radiant power) was tested, in triplicates, with three exposure times (5, 10 and 15 minutes). Potato Dextrose Agar (PDA) plates without the plate lid and containing Candida auris were exposed to UVC light. Subsequently, the plates were incubated at 36 °C for 48 h. Log reduction between treated and positive control (not exposed to UVC light) samples was calculated.
Results
At 15 minutes, we had the highest inactivation result, mean 4.43 log10, starting from a 1.5x106 CFU/mL concentration. At a higher concentration, 1.5X107 CFU/mL, the reduction had a mean of 3.51 log10.
Conclusions
The results of the experiments showed a significant microbial reduction in relation to the exposure time. The highest level of reduction was reached after 15 minutes of exposure. UVC chip had a relevant biocidal effect on Candida auris and may represent a valuable tool in the prevention of infections caused by this pathogen, which is becoming increasingly prevalent and persistent globally.
Key messages
• The use of UVC Chip decreases surface contamination.
• New technology against healthcare-associated infections

Cooperativas e desenvolvimento de comunidades: promessas e decepções.
O artigo apresenta os resultados de uma pesquisa que analisou a aplicação dos princÃpios cooperativos pelas organizações cooperativas e seus efeitos no desenvolvimento da comunidade onde estão inseridas, em estudo de caso realizado no municÃpio de Três Pontas, Minas Gerais. Após análise dos dados quantitativos e qualitativos, verificou-se que o cooperativismo trespontano apresenta inúmeras potencialidades que poderiam impulsionar um melhor desenvolvimento municipal, tanto pela atividade econômica exercida pelas cooperativas, como pelos projetos sociais que elas desenvolvem na vida associativa local. No entanto, não se aprecia sua articulação entre si e com as polÃticas públicas, de forma a conseguir um vigoroso desenvolvimento local
The Influence of Minority Stress, Gender, and Legalization of Civil Unions on Parenting Desire and Intention in Lesbian Women and Gay Men: Implications for Social Policy and Clinical Practice
Although the rate of lesbian and gay (LG) parents is increasing, lesbian and gay adults are less likely than heterosexual adults to be parents, as desire and intention to become a parent tend to be lower. This study aims at assessing 290 childless LG individuals (120 lesbian women and 170 gay men) to explore the influence of minority stress, gender differences, and legalization of civil unions in Italy on parenting desire and intention. The results indicated that the minority stressors associated with parenting dimensions included prejudice events, outness, and internalized homophobia
for lesbian women, but only felt stigma among gay men. Support from family or significant others buffered the effects of minority stressors on parenting dimensions. Thus, the minority stress processes partly explain the intention and desire to become parents in LG childless individuals. Furthermore, lesbian women showed higher levels of parenting desire and intention than gay men and the levels of these parenting dimensions increased after the law on civil unions was enacted. The findings have important implications for both social policies and clinical practice
Minority Stress, Resilience, and Mental Health: A Study of Italian Transgender People
Transgender people often experience oppression because of gender nonconformity. They represent an extremely stigmatized population at high risk of developing mental health problems. The minority stress model is a theoretical model used to understand social stigma as a potential cause of mental health disparities faced by the transgender population. In Italy, studies applying this model to the transgender population are limited. The current study applied the minority stress model to a sample of Italian transgender people (n = 149), analyzing effects of prejudice events, expectations of rejection, and internalized transphobia, and their interaction with protective factors (resilience and social support), on mental health. The results suggest that exposure to everyday discrimination and internalized transphobia are associated with increased mental health problems, while perceived social support from family and resilience significantly reduced the strength of association between everyday discrimination and mental health. Findings have important implications for both social issues and policies
Wind of change: Better air for microbial environmental control
Background: The COVID19 epidemic highlighted the importance of air in the transmission of pathogens. Air
disinfection is one of the key points to reduce the risk of transmission both in the health sector and in public, civil
and industrial environments. All bacteria and viruses tested to date can be inactivated by UV-C rays. Laboratory
tested UV-C systems are increasingly popular and proposed as effective technologies for air purification; few
studies have evaluated their performance in populated indoor environments. The aim of this investigation was to
evaluate the effectiveness of a UV-C disinfection system for air in a real working context.
Methods: This experimental study was conducted between December 2020 and February 2021 in an office of the
Department of Molecular and Developmental Medicine of the University of Siena, Italy. A pre-final version air
purifier (Cleaning Air T12), capable of treating 210 m3/h of air, was first tested for its ability to filter particulates
and reduce microbial air contamination in the absence of people. Subsequently, the experiments were conducted
in the presence of 3–5 subjects who worked for several hours in an office. During the tests, microbiological
samples of air were collected in real time, switching the system on and off periodically. Air samples were
collected and incubated on Petri dishes at 36 â—¦C and 22 â—¦C. Statistical analysis was performed with Stata 16
software assuming a significance level of 95%. An interpolating model was identified to describe the dynamics of
contamination reduction when the device operates.
Results: Preliminary tests showed a significant 62.5% reduction in Colony-Forming Units (CFUs) with 36 â—¦C
incubation. Reductions in the particulate component were also observed. In the main test, comparison of CFU
data, between the device-on phase (90 min) and the subsequent device-off phase (60 min), showed statistically
significant increase (p = 0.001) of environmental contamination passing from a mean of 86.6 (65.8–107.4) to
171.1 (143.9–198.3) CFU/m3, that is a rise of about 100%. The interpolating model exhibited a good fit of CFU
reduction trend with the device on.
Conclusions: The system, which mainly uses UV-C lamps for disinfection, was able to significantly reduce envi-
ronmental and human contamination in real time. Experimental tests have shown that as soon as the device is
switched off, after at least half an hour of operation, the healthiness of the air decreases drastically within 10
minutes, bringing the airborne microbial contamination (induced by the presence of operators in the environ-
ment) to levels even higher than 150% of the last value with the device on. Re-engineering strategies for system
improvement were also discusse
Contributions of implicit memory strategies to the rehabilitation of an amnesic patient: case report
Even severe amnesic patients usually are able to learn new information using implicit memory strategies. In the present study we describe our experience in the rehabilitation of an amnesic patient who had suffered cerebral anoxia. He was taught to use a computer text editor, enabling him to sheltered work. The training program lasted 14 weeks and was based on errorless learning and drilling practice techniques. The patient succeeded in all tasks, even though he could not remember accurately the training sessions. These results meet previous studies which point out that interaction between implicit and residual explicit memory can provide a basis new learning in amnesic patients. The domain-specific knowledge acquisition is demonstrating effectiveness in neuropsychological rehabilitation of brain injured patients.Mesmo pacientes severamente amnésticos são capazes de aprender informações novas, apoiados em estratégias de memória implÃcita. No presente estudo descrevemos uma experiência de reabilitação neuropsicológica, em que um paciente amnéstico, portador de lesão cerebral por anóxia, foi submetido a treino para uso de computador, visando sua capacitação semi-profissional. O treinamento teve duração de 14 semanas, e as técnicas de ensino utilizadas foram a prática repetitiva e a aprendizagem sem erros. O paciente obteve sucesso na realização das tarefas propostas, aprendendo a operar um editor de textos e mantendo o aprendizado após a passagem do tempo. Apesar disso, lembrava-se apenas vagamente da situação de aprendizagem. O presente estudo corrobora trabalhos anteriores que observam a interação entre mecanismos de memória implÃcita e resÃduos de memória explÃcita operando na aquisição de conhecimentos em pacientes amnésticos. A aprendizagem de conhecimentos especÃficos vem se mostrando eficiente para a reabilitação de pacientes que sofreram lesões cerebrais.Universidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Departamento de PsicobiologiaUNIFESP, EPM, Depto. de PsicobiologiaSciEL
Safer school with near-UV technology: novel applications for environmental hygiene
Systems capable of disinfecting air and surfaces could reduce the risk of infectious diseases transmission. Aim: to evalu-ate the effectiveness of near-UV LED ceiling lamps, with a wavelength of 405 nm, in improving environmental hygiene. Between November and December 2020, we conducted an experimental study having a pre-post design in a kindergarten room in Siena where 4 ceiling lamps with 405 nm LED technology were installed. Twice per day, sampling was performed before (T0) and after treatment with near-UV (T1). We used between 8 and 12 pairs of contact plates to sample at various random spots each day. Air samplings were also performed. The plates were incubated at 22 and 36 degrees C. Significance was set at 95% (p < 0.05). The mean level of Colony Forming Unit (CFU) at T(0) was 249 (95% CI 193.1 - 305.0) at 36 degrees C and 535.2 (374.3 - 696.1) at 22 degrees C. The reduction was significant at T(1): by 65% at 36 degrees C and, 72% at 22 degrees C. Also, for air contamination: 95.3% (98.4 & mdash;92.3). A dose threshold of about 5 J/cm2 was identified to have an 80% CFU abatement and remains nearly constant. The advantage of being able to use this technology in the presence of people is very important in the context of controlling environmental contamination. © 2023, The Author(s)
EARLINET: towards an advanced sustainable European aerosol lidar network
The European Aerosol Research Lidar Network, EARLINET, was founded in 2000 as a research project for establishing a quantitative, comprehensive, and statistically significant database for the horizontal, vertical, and temporal distribution of aerosols on a continental scale. Since then EARLINET has continued to provide the most extensive collection of ground-based data for the aerosol vertical distribution over Europe.
This paper gives an overview of the network's main developments since 2000 and introduces the dedicated EARLINET special issue, which reports on the present innovative and comprehensive technical solutions and scientific results related to the use of advanced lidar remote sensing techniques for the study of aerosol properties as developed within the network in the last 13 years.
Since 2000, EARLINET has developed greatly in terms of number of stations and spatial distribution: from 17 stations in 10 countries in 2000 to 27 stations in 16 countries in 2013. EARLINET has developed greatly also in terms of technological advances with the spread of advanced multiwavelength Raman lidar stations in Europe. The developments for the quality assurance strategy, the optimization of instruments and data processing, and the dissemination of data have contributed to a significant improvement of the network towards a more sustainable observing system, with an increase in the observing capability and a reduction of operational costs.
Consequently, EARLINET data have already been extensively used for many climatological studies, long-range transport events, Saharan dust outbreaks, plumes from volcanic eruptions, and for model evaluation and satellite data validation and integration.
Future plans are aimed at continuous measurements and near-real-time data delivery in close cooperation with other ground-based networks, such as in the ACTRIS (Aerosols, Clouds, and Trace gases Research InfraStructure Network) www.actris.net, and with the modeling and satellite community, linking the research community with the operational world, with the aim of establishing of the atmospheric part of the European component of the integrated global observing system.Peer ReviewedPostprint (published version
