Comprehensive assessment for hygrothermal comfort with heat and mass fluxes through a clothing layer during cooling seasons.

A comprehensive analysis is carried out for achieving hygrothermal comfort by using bidirectional heat and mass fluxes between the human skin and its surroundings during cooling seasons, considering the main characteristics of climate, metabolic rate, and clothing fabrics. As hygrothermal comfort is mainly seen as one-direction heat and mass flux from the close surroundings to the human body, without the emitted heat and mass by the human skin, the purpose of the analysis is to find out proper features of the respective clothing fabric according to the inlet boundary conditions, i.e. heat and mass flux from the human body, and the outlet boundary features, i.e. heat and mass flux due to the climate conditions. Thereby, a novel mathematical modelling is developed for heat and mass transfer, respectively. Then, the software Wolfram Mathematica is applied for the numerical solutions of the model. After the model is validated, a sensitivity analysis is carried out. Thereby, it is found that the sensible heat removal by convection, dependent on both airflow and humidity rates, has a great influence on the hygrothermal comfort. Furthermore, solar reflectivity for shortwave radiation, along with longwave radiation from the skin, have influence on the hygrothermal comfort when both ventilation and sweating are set as minimum. Therefore, if the conditions of temperature and relative humidity are proper, both high conductivity and air permeability clothes are recommended. Nevertheless, regarding the reflectivity, it depends on the presence of shortwave radiation, sweating, ventilation, and longwave radiation to consider light-toned or dark colors.

Evaluation of fluid leakage at the coverall and glove interface in single and double glove conditions.

BACKGROUND: Fluid leakage through the glove-protective clothing interface is an area of concern for many health care personnel, including emergency medical service providers, who may wear coveralls to protect themselves from multiple types of hazards. There is currently no established standard test method to specifically evaluate the barrier performance of the glove-protective clothing interface region for any personal protective equipment ensemble. OBJECTIVE: This study quantifies the fluid leakage at the coverall and glove interface using single and double gloving. METHODS: A robotic arm, which can simulate upper extremity movements of health care personnel, was used to test 5 coverall models and an extended examination glove model in single and double glove conditions. RESULTS: The results show that there was a significant difference in fluid leakage amounts between some of the coverall models and the number of glove layers studied. Findings also highlight that there is a high correlation between basis weight and stiffness of the coverall fabrics and the fluid leakage amounts. CONCLUSIONS: These results underline that coverall constructed from thin and less stiff fabrics can result in lower fluid leakage levels. Also, there was no significant difference in fluid leakage amounts between single and double gloves when tested with each of the coverall models, with the exception of the coveralls with the highest basis weight and stiffness.

Key drivers of the textile and clothing industry decarbonisation within the EU-27.

The European Union has identified the Textile and Clothing industry as one of the essential objectives towards carbon neutrality in 2050 in line with the "European Green Deal". There are no previous research papers focused on analysing the drivers and inhibitors of the past greenhouse gas emission changes of the textile and clothing industry in Europe. This paper aims to analyse the determinants of the changes in these emissions, and the disassociation level between emissions and economic growth, throughout the 27 Member States of the European Union, from 2008 to 2018. A Logarithmic Mean Divisia Index that explains the key drivers of the changes in greenhouse gas emissions of European Union Textile and Cloth industry and a Decoupling Index have been applied. The results generally conclude that the intensity and carbonisation effects are key factors that contribute to reducing greenhouse gas emissions. The lower relative weight of the textile and clothing industry throughout the EU-27 was noteworthy, and favours lower emissions, partially counteracted by the activity effect. Also, most Member States have been decoupling the industry's emissions from economic growth. Our policy recommendation shows that if further reductions in greenhouse gas emissions are to be achieved, energy efficiency improvements and cleaner use of energy sources would offset the potential increase in emissions of this industry as a result of a relative increase in its gross value added.

White Light-Photolysis for the Removal of Polycyclic Aromatic Hydrocarbons from Proximity Firefighting Protective Clothing.

The presence of polycyclic aromatic hydrocarbons (PAHs) on firefighters' personal protective equipment is a concern. One form of preventing from these compounds is to decontaminate proximity firefighting protective clothing (PFPC). Traditional decontamination methods do not promote total removal of pollutants and alter the properties of PFPC. The objective of this work was to evaluate the effectiveness of white light-photolysis (WLP), an advanced oxidation process (AOP), for removing PAHs from PFPC, while maintaining the integrity of the fabric fibers. Experiments were carried out, varying reaction time and concentration of H2O2. With WLP (without H2O2), it was possible to remove more than 73% of the PAHs tested from the outer layer of PFPC in 3 days. The WLP provided the greatest removal of PAHs, compared with the most common mechanical decontamination techniques (laundering and wet-soap brushing). The fibers' integrity after exposure to the white light was evaluated with infrared spectroscopy and scanning electron microscopy/energy dispersive X-ray spectrometry. In addition, a tearing strength test was performed. No remarkable fabric degradation was observed, indicating a possible, routine-compatible, simple, and inexpensive method of decontamination of PFPC, based on photolysis, which is effective in the degradation of PAHs and maintains the integrity of fabric fibers.

Design of a Naturally Dyed and Waterproof Biotechnological Leather from Reconstituted Cellulose.

Consumerism in fashion involves the excessive consumption of garments in modern capitalist societies due to the expansion of globalisation, especially at the beginning of the 21st Century. The involvement of new designers in the garment industry has assisted in creating a desire for new trends. However, the fast pace of transitions between collections has made fashion increasingly frivolous and capable of generating considerable interest in new products, accompanied by an increase in the discarding of fabrics. Thus, studies have been conducted on developing sustainable textile materials for use in the fashion industry. The aim of the present study was to evaluate the potential of a vegan leather produced with a dyed, waterproof biopolymer made of reconstituted bacterial cellulose (BC). The dying process involved using plant-based natural dyes extracted from Allium cepa L., Punica granatum, and Eucalyptus globulus L. The BC films were then shredded and reconstituted to produce uniform surfaces with a constant thickness of 0.10 cm throughout the entire area. The films were waterproofed using the essential oil from Melaleuca alternifolia and wax from Copernicia prunifera. The characteristics of the biotechnological vegan leather were analysed using scanning electron microscopy (SEM), thermogravimetric analysis (TGA), flexibility and mechanical tests, as well as the determination of the water contact angle (°) and sorption index (s). The results confirmed that the biomaterial has high tensile strength (maximum: 247.21 ± 16.52 N) and high flexibility; it can be folded more than 100 times at the same point without breaking or cracking. The water contact angle was 83.96°, indicating a small water interaction on the biotextile. The results of the present study demonstrate the potential of BC for the development of novel, durable, vegan, waterproof fashion products.

Historical overview and update on relapsing fever group Borrelia in Latin America.

Relapsing fever group Borrelia (RFGB) are motile spirochetes transmitted to mammalian or avian hosts through the bite of hematophagous arthropods, such as soft ticks (Argasidae), hard ticks (Ixodidae) and the human clothing lice. RFGB can infect pets such as dogs and cats, as well as birds, cattle and humans. Borrelia recurrentis, B. anserina and B. theileri are considered to have worldwide distribution, affecting humans, domestic birds and ruminants, respectively. Borrelia spp. associated with soft ticks are transmitted mainly by Ornithodoros ticks and thrive in endemic foci in tropical and subtropical latitudes. Nowadays, human cases of soft tick-borne relapsing fever remain neglected diseases in several countries, and the impact these spirochetes have on the health of wild and domestic animals is largely understudied. Human infection with RFGB is difficult to diagnose, given the lack of distinguishing clinical features (undifferentiated febrile illness). Clinically, soft tick or louse-borne relapsing fever is often confused with other etiologies, such as malaria, typhoid or dengue. In Latin America, during the first half of the twentieth century historical documents elaborated by enlightened physicians were seminal, and resulted in the identification of RFGB and their associated vectors in countries such as Mexico, Panama, Colombia, Venezuela, Peru and Argentina. Almost 80 years later, research on relapsing fever spirochetes is emerging once again in Latin America, with molecular characterizations and isolations of novel RFGB members in Panama, Bolivia, Brazil and Chile. In this review we summarize historical aspects of RFGB in Latin America and provide an update on the current scenario regarding these pathogens in the region. To accomplish this, we conducted an exhaustive search of all the published literature for the region, including old medical theses deposited in libraries of medical academies. RFGB were once common pathogens in Latin America, and although unnoticed for many years, they are currently the focus of interest among the scientific community. A One Health perspective should be adopted to tackle the diseases caused by RFGB, since these spirochetes have never disappeared and the maladies they cause may be confused with etiologies with similar symptoms that prevail in the region.

En este contexto, el uso de los elementos de protección personal tomó un especial interés, en especial para la atención del trabajo de parto vaginal, dada la confusión en los círculos obstétricos respecto a la mejor forma de proteger al personal sanitario en dichos casos. El objetivo de este artículo de revisión es identificar cuáles son los elementos de protección personal indicados en la atención del parto vaginal y su correcto uso en tiempos de COVID-19. División de temas tratados. Se realizó una revisión narrativa de la literatura accediendo a las bases de datos: PubMed, Medline, Elsevier, Google Académico y sitios web como la Organización Mundial de la salud (OMS), Centros para el Control y la Prevención de Enfermedades (CDC, por sus siglas en inglés) y el Colegio Americano de Obstetras y Ginecólogos (ACOG), entre otros. Se usaron palabras claves como "Infecciones por Coronavirus", "Parto Normal", "Protección Personal", "Personal de Salud", "Dispositivos de Protección Respiratoria" y "Dispositivos de Protección de los Ojos". La literatura permitió identificar aspectos introductorios al tema, epidemiología, características generales de los elementos de protección personal, y los elementos específicos para el uso correcto en la atención del parto vaginal. Conclusiones. El trabajo de parto es considerado como un procedimiento generador de aerosoles, por lo que se recomienda principalmente el uso de tapabocas N95 o un respirador que ofrezca mayor protección para personal de salud en la atención del parto vaginal, con el fin de evitar la infección por SARS-CoV-2; sin embargo, se debe insistir en el uso adecuado y completo de los elementos de protección personal como lo son la bata quirúrgica, el gorro, el protector ocular y guantes, independientemente de la sintomatología de la paciente.

Introduction. In December 2019, in Wuhan, China, there was an outbreak of atypical pneumonia caused by the SARS-CoV-2 virus, which is a type of coronavirus causative of COVID-19, which overtime became a pandemic. In this context, the use of personal protective equipment is of special interest, especially when providing care in vaginal delivery, due to the confusion in obstetric circles regarding the best way to protect healthcare personnel in these cases. The objective of this review article is to identify which are the personal protective elements indicated for providing care in vaginal birth and their correct use during COVID-19. Division of Covered Topics. A narrative review of the literature was carried out, accessing the following databases: PubMed, Medline, Elsevier, Google Scholar, and websites such as the World Health Organization (WHO), Center for the Control and Prevention of Diseases (CDC), and the American College of Obstetricians and Gynecologists, among others. Keywords such as "Coronavirus Infections", "Normal Birth," Personal Protective Elements," "Healthcare Personnel", "Respiratory Protective Devices", and "Eye Protection Devices" were used. The literature allowed us to identify introductory aspects on the matter, epidemiology, general characteristics of personal protective elements, and the specific elements for correct use when providing care in vaginal birth. Conclusions. Labor is considered an aerosol-generating procedure. Therefore, the main recommendation is the use of an N95 mask or a respirator which allows for greater protection for healthcare personnel when assisting vaginal birth, in order to avoid infection due to SARS-CoV-2. However, there must be an adequate and complete use of personal protective equipment, such as surgical gowns, hats, eye protection and gloves, regardless of the patient's symptomatology

Wearables and their applications for the rehabilitation of elderly people.

Globally, there has been a change in the population pyramid with an accelerated aging process. This increase requires a greater challenge to maintain autonomy and independence. Currently, there are technologies developed with a focus on health. This is given by the development of wearables and their areas of applications. As a general context, this technology is characterized by the research field in energy generation, the development of external devices for human control and monitoring, clothing, smart textiles, and electronics. The latter are classified into three areas of application: monitoring and safety; fabrics, perception, and physical activity; and rehabilitation. A literature review is conducted to identify the state-of-the-art in these fields within the last years. The progress in monitoring systems and intelligent textiles is evidenced, being able to highlight remote feedback, materials, and wearability both at a commercial and user level. A discussion is included to address the main challenges and future trends in the application of wearables in elderly people.

Worrying levels of antimicrobial resistance in Gram-negative bacteria isolated from cell phones and uniforms of Peruvian intensive care unit workers.

BACKGROUND: Healthcare worker (HCW) uniforms and cell phones are involved in pathogen transmission. This study aimed to characterize pathogenic microorganism isolates from HCW uniforms and cell phones. METHODS: Gram-negative microorganisms were recovered from HCW uniforms and cell phones. Antimicrobial susceptibility and the presence of extended-spectrum ß-lactamases (ESBL) and carbapenemases were determined. RESULTS: Escherichia coli was the most prevalent microorganism. Overall, high levels of resistance to cephalosporins, quinolones, co-trimoxazole and colistin were found. ESBL were mainly related to blaCTX-M-15 and blaSHV- genes. Carbapenem-resistant isolates presented as blaKPC or blaNDM. CONCLUSIONS: High levels of antimicrobial resistance, including colistin, were detected. Therefore, strategies are urgently needed to prevent bacterial dissemination.

Risks related to the domestic laundering of filling station attendant uniforms: advances and uncertainties.

Gasoline is the most common transportation fuel in Brazil, with up to 1% of benzene. Benzene is a health-damaging organic solvent that is extensively used worldwide, being classified as a human carcinogen by the International Agency for Research on Cancer (Group 1). Many workers at filling stations are exposed to benzene, present in gasoline. The main routes of exposure and absorption of benzene are inhalation, oral, and dermal routes. The penetration and maintenance of benzene and other chemicals on personal protective equipment and clothing of workers who manipulate these solvents may increase their levels of exposure and offer risks to their family members, since contaminated clothing is laundered at their homes, which goes against legislative framework (Annex 2, Regulatory Standard No. 9). This way, the objective of this work was to discuss the importance of periodic changes and cleaning of filling station attendant uniforms performed by employers as preventive measures against the deterioration of the health of workers and their family members. We performed a narrative review; no systematic criteria were used in the search for national and international studies. After critical reading, we observed a lack of consistent data on this theme. Laundering of uniforms worn by filling station attendants should take place outside the domestic environment in order to protect the health of workers and their family members and avoid possible cross-contamination.

A simulation study to assess fluid leakage through the glove-gown interface in isolation settings.

BACKGROUND: Isolation gowns are recommended to protect healthcare personnel, patients, and visitors from transfer of microorganisms and body fluids in patient isolation situations. Standards provide limited information about barrier performance of isolation gowns for possible exposure scenarios. One of the most vulnerable areas of the personal protective equipment ensemble is considered the glove-gown interface. However, current isolation gown classification standards do not consider the interface regions of the personal protective equipment system while assessing the level of protection. The purpose of this study was to quantitatively evaluate the fluid leakage through the glove-gown interface by simulating exposures and healthcare personnel arm movements in patient care for isolation settings. METHODS: We tested fluid leakage of two examination gloves with different cuff lengths and seven isolation gown models designed with varying levels of barrier resistance and multiple cuff types. RESULTS: Our results demonstrated that leakage through the glove-gown interface depends on multiple factors, including glove cuff length and gown cuff design. Gowns with the thumb loop design provided better protection than the elastic cuff design, and the elastic cuff design provided better protection compared to the knit cuff design for a given AAMI PB70 level. More importantly, a substantial penetration through gown fabrics was observed. CONCLUSIONS: This research identifies a need to develop a standardized method to evaluate leakage at the glove-gown interface to improve worker protection.

As repercussões da gravidez no cotidiano de uma mulher / The Repercussions of Pregnancy in a Woman's Everyday

Objetivo: Descrever as repercussões da gravidez no cotidiano de uma mulher. Métodos: Estudo exploratório-descritivo com abordagem qualitativa. Foram entrevistadas 25 gestantes entre 20 e 24 semanas de gestação, atendidas em uma instituição na cidade de Fortaleza (CE). A coleta de dados foi por meio de entrevistas semiestruturadas, submetidas à técnica de análise de conteúdo. Foram criadas nuvens de palavras para as categorias, utilizando-se o software NVivo 11. Resultados: A análise comparativa constante permitiu a construção de duas categorias: "impacto da gravidez nas atividades diárias" e "peso corporal da gestação na moda feminina". A primeira categoria demonstrou o impacto do aumento do tamanho corporal da gestante diante das atividades comuns do dia a dia, a dificuldade para realizar certas atividades, a sobrecarga das articulações e o cansaço relacionado ao aumento do volume corporal na gestação. Os resultados da segunda categoria mostraram que as mudanças gestacionais impactam nas escolhas de vestimenta das mulheres, sendo relatadas as dificuldades para aquisição de um novo vestuário durante esta fase, a procura por lojas especializadas em moda gestante e o reaproveitamento de peças existentes com necessidade de possíveis ajustes. Conclusão: Neste estudo, possibilitou-se a análise dos sentidos atribuídos às mudanças corporais pelas gestantes e observou-se que as transformações gestacionais repercutem diretamente na realização de atividades cotidianas e nas escolhas de vestimenta de mulheres grávidas, demonstrando inúmeras dificuldades a serem compreendidas e enfrentadas durante este período.

Objective: To describe the repercussions of pregnancy on a woman's daily life. Methods: Exploratory-descriptive study with a qualitative approach. Twenty-five pregnant women were interviewed between 20 and 24 weeks of gestation, attended at an institution in the city of Fortaleza (CE). Data collection was carried out through semi-structured interviews that were submitted to the content analysis technique. Word clouds were created for the categories, using the software NVivo 11. Results: The constant comparative analysis allowed the construction of two categories: "impact of pregnancy on daily activities" and "body weight of pregnancy on women's fashion". The first category demonstrated the impact of the increase in body size of the pregnant woman facing common daily activities, the difficulty to perform certain activities, the overload of the joints and the tiredness related to the increase in body volume in pregnancy. The results of the second category showed that gestational changes impact women's clothing choices, with difficulties reported for the acquisition of new clothing during this phase, the search for stores specializing in pregnant fashion and the reuse of existing pieces in need of possible adjustments. Conclusion: The study made it possible to analyze the meanings attributed to the body changes by pregnant women and it was observed that gestational changes have a direct impact on the performance of daily activities and on the clothing choices of pregnant women, demonstrating numerous difficulties to be understood and faced during this period.

The use of antimicrobial-impregnated fabrics in health services: an integrative review / Utilização de têxteis impregnados com antimicrobianos nos serviços de saúde: revisão integrativa / Utilización de textiles impregnados con antimicrobianos en los servicios sanitarios: revisión integradora

Objective: to analyze evidence concerning the feasibility of antimicrobial-impregnated fabrics in preventing and controlling microbial transmission in health services. Method: an integrative review using the following databases: MEDLINE (via PubMed), Web of Science, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Scopus, and Latin American and Caribbean Health Sciences Literature (LILACS), regardless of language and date of publication. Seven studies were included in the analysis to verify the types of fabrics and substances used to impregnate the fabrics, applicability in health services, and decrease in microbial load. Results: silver nanoparticles and copper oxide are the main antimicrobial substances used to impregnate the fabrics. The patients' use of these fabrics, such as in bed and bath linens and clothing, was more effective in reducing antimicrobial load than in health workers' uniforms. Conclusion: the use of these antimicrobial-impregnated textiles, especially by patients, is a viable alternative to prevent and control microbial transmission in health services. Implementing these fabrics in health workers' uniforms requires further studies, however, to verify its effectiveness in decreasing microbial load in clinical practice.

Cogniciones en el lado oscuro: desconexión moral, tríada oscura y conducta antisocial en adolescents / Cognitions on the dark side: Moral disengagement, dark triad and antisocial behavior in adolescents

Resumen En el marco de una tradición de investigación relativamente reciente, ciertos rasgos psicológicos relacionados con diversas conductas socialmente reprobables se han agrupado bajo la denominación de "Factor o lado oscuros de la personalidad". En este contexto, este trabajo estudia la varianza común que pudiera existir entre los tres componentes del constructo tríada oscura (maquiavelismo, narcisismo y psicopatía) y los procesos cognitivos constitutivos del constructo desconexión moral, en orden a relacionarlos con la conducta antisocial de una muestra de 800 adolescentes (M = 15.33, SD = .99; 50.1 % chicos). El análisis factorial exploratorio sugirió retener cuatro factores mediante el Análisis Paralelo de Horn. Estos factores se sometieron a una rotación bifactorial en el contexto exploratorio, y sus índices de ajuste fueron adecuados ꭓ² (1219.42, 737) = 1.65 p < .05; RMSEA = .03 (.01, .05 ); CFI = .98. El análisis factorial confirmatorio de este modelo bifactorial para representar el lado oscuro, obtuvo índices de ajuste óptimos ꭓ² (392.38, 150) = 2.61 p < .05; RMSEA = .04 (.04, .05); CFI = .95; y similar para chicos y chicas. El modelo de ecuaciones estructurales indicó que el "lado oscuro", entendido aquí como las características comunes de la tríada oscura y la desconexión moral, está directa e intensamente relacionado con conductas antisociales en chicas (β = .57, p < .001) y en chicos (β = .54, p < .001). Finalmente, se discuten las implicaciones de estos resultados para la prevención de una amplia gama de conductas antisociales en adolescentes.

Abstract Within the context of a recent research tradition, certain psychological traits related to various socially reprehensible behaviors have been grouped under the name of "Dark Factor or dark side of personality." In this context, this paper studies the common variance that could exist between the three components of the Dark Triad construct (Machiavellianism, Narcissism and Psychopathy) and the constituent cognitive processes of Moral Disengagement construct, in order to relate them to the antisocial behavior of a sample composed of 800 adolescents (M = 15.36, SD = .99; 50.1 % boys). Exploratory factor analysis suggested retaining four factors using Horn Parallel Analysis. These factors were subjected to a bifactorial rotation in the exploratory context, and their fit indices were adequate ꭓ² (1219.42, 737) = 1.65 p <.05; RMSEA = .03 (.01, .05); CFI = .98. The confirmatory factor analysis of this bifactorial model to represent the dark side obtained optimal fit indices ꭓ² (392.38, 150) = 2.61 p <.05; RMSEA = .04 (.04, .05); CFI = .95; similar for boys and girls. The results of the structural equation model indicated that the "dark side", understood here as the common characteristics of the Dark Triad and Moral Disengagement, is directly and intensely related to antisocial behaviors in girls (β = .57, p < .001) and boys (β = .54, p < .001). Finally, the implications of these results for the prevention of a wide range of antisocial behaviors in adolescents are discussed.

Preliminary Evaluation of Human Personal Protective Measures Against the Nymphal Stage of the Asian Longhorned Tick (Acari: Ixodidae).

The invasive, human-biting Asian longhorned tick, Haemaphysalis longicornis Neumann, is establishing in the United States. This tick is a threat to public health in its native range in Asia, serving as a vector of severe fever with thrombocytopenia syndrome virus and Rickettsia japonica, the agent of Japanese spotted fever. However, there is a lack of published information specifically for H. longicornis concerning the efficacy of generally recommended personal tick bite prevention measures. We, therefore, evaluated permethrin-treated clothing and formulated human skin repellent products, representing the six repellent active ingredients generally recommended for tick bite prevention by the Centers for Disease Control and Prevention (CDC), against H. longicornis nymphs from a colony established with adult ticks collected in New York state. Reluctance of H. longicornis nymphs to stay in contact with nontreated human skin precluded the use of a human skin bioassay to optimally evaluate repellency. In a Petri dish choice bioassay, all tested product formulations were highly effective with estimated repellencies ranging from 93 to 97%. In addition, we observed strong contact irritancy of a summer-weight permethrin-treated garment against H. longicornis nymphs, with 96% of introduced ticks dislodging from the vertically oriented textile within 3 min. These preliminary studies indicate that personal tick bite prevention measures currently recommended by the CDC are effective against the invasive H. longicornis. However, additional studies are needed to explore the efficacy of the evaluated products against different life stages of H. longicornis, as well as ticks collected in the field rather than reared in the laboratory.

Jalecos em têxteis de poliéster agem como barreira contra fluidos e bactérias? / ¿Batas médicas de telas de poliéster actúan como barrera contra fluidos y bacterias? / Do white coats on polyester fabrics act as a barrier against fluids and bacteria?

Resumo Objetivo Avaliar tecidos de poliéster quanto à função de barreira física contra fluidos e bactérias. Métodos Trata-se de uma pesquisa experimental laboratorial in vitro realizada em três etapas: avaliação do tempo de passagem de fluido através dos tecidos, cronometrado desde o início do escoamento do fluido até a formação e queda da última gota; determinação microbiológica da carga bacteriana presente no fluido, após a sua passagem através dos tecidos; e análise das características estruturais dos tecidos por meio de microscopia eletrônica de varredura. Os dados foram submetidos aos testes de normalidade e ao teste de U de Mann-Whitney, com nível de significância de a=5%. Resultados as comparações dos tempos obtidos na primeira etapa entre os dois tipos de tecidos utilizados demonstraram diferença estatística ( p <0,001). Com relação à avaliação microbiológica, não foi observada diferença entre as cargas bacterianas após a passagem do fluido através dos tecidos, tanto para Staphylococcus aureus ( p =0,056) quanto para Pseudomonas aeruginosa ( p= 0,320). A análise por microscopia eletrônica de varredura evidenciou diferenças estruturais entre os tecidos, no entanto não foi constatada a presença bacteriana na superfície dos tecidos. Conclusão Ambos os tecidos de poliéster empregados para confecção de jalecos não apresentaram função de barreira física contra fluidos e bactérias. Assim, os resultados nos permitem especular que o jaleco de poliéster ao entrar em contato com fluidos corporais pode possibilitar a contaminação do profissional.

Abstract Objective To evaluate polyester fabrics as physical barrier function against fluids and bacteria. Methods This is an in vitro experimental laboratory research carried out in three stages: evaluation of the length of time for the fluid to pass through the fabrics, timed from the beginning of the fluid flow until the formation and fall of the last drop; microbiological determination of the bacterial load in the fluid, after its passage through the fabrics; and analysis of the structural characteristics of the fabrics by scanning in electron microscopy. The data were submitted to normality tests and the Mann-Whitney U test, with a significance level of a=5%. Results Comparisons of length of time in the first stage between the two types of fabrics used showed a statistical difference ( p <0.001). Regarding the microbiological evaluation, there was no difference among bacterial loads after the fluid passed through the fabrics, both for Staphylococcus aureus ( p =0.056) and Pseudomonas aeruginosa ( p =0.320). The analysis by scanning electron microscopy showed structural differences between the fabrics, however, there were no bacteria on the fabric surface. Conclusion Both polyester fabrics used to make white coats did not work as a physical barrier against fluids and bacteria. Thus, the results allowed us to speculate that the polyester coat when in contact with body fluids may allow contamination of the professional.

A brief history of medical uniforms: from ancient history to the COVID-19 time / Uma breve história de uniformes médicos: da história antiga aos tempos da COVID-19

ABSTRACT Medical Uniforms date back from medieval times. Nursing uniforms were based on nuns clothes whereas doctors used the famous "plague costumes" and black "frock" coats from about 15th to early 19th century. In latter half 19th century medical uniforms started to change. Nursing uniforms gradually lost their similarities to religious outfits. Doctors started to use white clothing. With great emphasis on hygiene and sanitation, the idea of personal protective equipment (PPE) started to evolve with William Stewart Halsted introducing the use of rubber gloves in 1889. In the 1960s-1970s it became more usual to wear green and blue `scrubs in order to look for a greater contrast in clothing with the all-white hospital environment. In contemporary times, some specialties even stopped using specific uniforms, while others still use them. At the same time, PPE became more and more important, up to nowadays "plague costume" in the combat of the COVID-19 epidemics.

RESUMO Uniformes da área médica datam desde os tempos medievais. Uniformes de enfermeiras eram baseados em roupas de freiras, enquanto o de médicos eram caracterizados pelas "vestimentas da praga" e fraques pretos de meados do século 15 até o início do século 19. No final do século 19, os uniformes começaram a mudar. A vestimenta de enfermeiras perderam suas similaridades com vestes religiosas. Médicos começaram a usar roupas brancas. Com o aumento da ênfase em higiene e no sanitarismo, começa a evoluir a ideia do uso de equipamento de proteção individual (EPI), com William Stewart Halsted utilizando luvas de borracha pela primeira vez em 1889. Nas décadas de 1960 e 1970 começa a se tornar mais usual a adesão ao pijama cirúrgico verdes e azul como roupa hospitalar, devido ao contraste com o ambiente branco já presente. Na contemporaneidade, algumas especialidades deixaram de usar uniformes específicos, enquanto outras ainda a usam. Ao mesmo tempo, EPIs tornaram-se mais e mais importantes, até, hoje em dia, surgir as "vestimentas da praga" atualizadas para o combate da epidemia do COVID-19.
