Contamination of equipment and surfaces in the operating room anesthesia workspace: a cross-sectional study

ABSTRACT BACKGROUND: Contamination of the breathing circuit and medication preparation surface of an anesthesia machine can increase the risk of cross-infection. OBJECTIVE: To evaluate the contamination of the anesthetic medication preparation surface, respiratory circuits, and devices used in general anesthesia with assisted mechanical ventilation. DESIGN AND SETTING: Cross-sectional, quantitative study conducted at the surgical center of a philanthropic hospital, of medium complexity located in the municipality of Três Lagoas, in the eastern region of the State of Mato Grosso do Sul. METHODS: Eighty-two microbiological samples were collected from the breathing circuits. After repeating the samples in different culture media, 328 analyses were performed. RESULTS: A higher occurrence of E. coli, Enterobacter spp., Pseudomonas spp., Staphylococcus aureus, and Streptococcus pneumoniae (P < 0.001) were observed. Variations were observed depending on the culture medium and sample collection site. CONCLUSION: The study findings underscore the inadequate disinfection of the inspiratory and expiratory branches, highlighting the importance of stringent cleaning and disinfection of high-touch surfaces.

Racismo e Sexismo: Estruturas de Transmissão, Incidências da História e Insistências do Real / Racism and Sexism: Transmission Structures, History Incidences and Insistences of the Real / Racismo y Sexismo: Estructuras de Transmisión, Incidencias de la Historia e Insistencias de lo Real

Este artigo propõe articulações entre as estruturas coloniais de incidência do racismo e do sexismo no laço social e suas vias de inscrição no inconsciente e no corpo. Partimos de um debate sobre o enquadre colonial da subjetividade e de questões levantadas por Frantz Fanon acerca do modo como o racismo se conecta com a lógica fálica do complexo de Édipo para avaliar sua validade em relação à realidade de povos colonizados. Retomamos formulações freudianas e lacanianas úteis para abordar essa encruzilhada, a partir dos caminhos apontados por Lélia Gonzalez ao discutir as subversões operadas pela mulher negra diante do racismo e do sexismo no contexto brasileiro. Com base em alguns fragmentos clínicos, sustentamos que uma abordagem clínica da perspectiva interseccional antecipada por Lélia Gonzalez demanda uma tomada dialética das relações entre estrutura e história, entre o coletivo e o singular e entre o inconsciente colonizado e o resto que escapa e subverte as relações de dominação.

This article proposes articulations between the colonial structures of incidence of the racism and sexism in the social bond and their ways of inscription in the unconscious and in the body. Starting from a debate about the colonial framework of subjectivity and from questions raised by Frantz Fanon about how the racism connects with the phallic logic of the Oedipus complex to assess its validity in relation to the reality of colonized peoples. We return to useful Freudian and Lacanian formulations to address this crossroads, based on the paths pointed out by Lélia Gonzalez when discussing the subversions operated by black women in the face of racism and sexism in the Brazilian context. Based on some clinical fragments, we argue that a clinical approach to the intersectional perspective anticipated by Lélia Gonzalez demands a dialectical approach to the relations between structure and history, between the collective and the singular, and between the colonized unconscious and the rest that escapes and subverts the relations of domination.

Este artículo propone articulaciones entre las estructuras coloniales de incidencia del racismo y del sexismo en el lazo social y sus formas de inscripción en el inconsciente y en el cuerpo. Partimos de un debate sobre el marco colonial de la subjetividad y de las preguntas planteadas por Frantz Fanon sobre la forma en que el racismo se relaciona con la lógica fálica del complejo de Edipo para evaluar su validez con relación a la realidad de los pueblos colonizados. Retomamos formulaciones freudianas y lacanianas útiles para abordar esta encrucijada, a partir de los caminos señalados por Lélia González al discutir las subversiones operadas por las mujeres negras frente al racismo y al sexismo en el contexto brasileño. En función de algunos fragmentos clínicos, sostenemos que una aproximación clínica de la perspectiva interseccional, anticipada por Lélia González, exige un abordaje dialéctico de las relaciones entre estructura e historia, entre lo colectivo y lo singular y entre el inconsciente colonizado y el resto que escapa y subvierte las relaciones de dominación.

Mobile phones of anesthesiologists as reservoirs of nosocomial bacteria in a quaternary teaching hospital: an observational study

Abstract Background: Mobile phones in hospital settings have been identified as an important source of cross-contamination because of the low frequency with which mobile phones are cleaned by health workers and cyclical contamination of the hands and face. The aim of this study was to investigate whether the mobile phones of the anesthesia team at a teaching hospital are potential reservoirs of nosocomial bacteria. In addition, differences in device sanitization and hand hygiene habits between attending and resident anesthesiologists were correlated with mobile phone colonization. Methods: A prevalence study was conducted over a 6-month period from 2017 to 2018 that involved the collection of samples from the mobile phones of the anesthesiology team and culturing for surveillance. A questionnaire was administered to assess the mobile phone sanitization and hand washing routines of the anesthesia team in specific situations. Results: Bacterial contamination was detected for 86 of the 128 mobile phones examined (67.2%). A greater presence of Micrococcus spp. on devices was correlated with a higher frequency of mobile phone use (p = 0.003) and a lower frequency of sanitization (p = 0.003). The presence of bacteria was increased on the mobile phones of professionals who did not perform handwashing after tracheal intubation (p = 0.003). Conclusion: Hand hygiene and device sanitization habits were more important than the use behavior, as a higher presence of bacteria correlated with poorer hygiene habits. Furthermore, handwashing is the best approach to prevent serious colonization of mobile devices and the possible transmission of pathogens to patients under the care of anesthesiologists.

Seasonal Variation of Mycorrhizal Association (Root Colonization and Spore Density) in Selected Industrial Sites in Kota District of Rajasthan, India

This paper aims to assess the impact of seasonal variation on mycorrhizal association in selected industrial wastelands in the Kota district of Rajasthan. In the study mycorrhizal association was quantified in terms of percentage root colonization and spore density in three different seasons. The study was conducted during 2019-2021 and the data was collected for 3 seasons; summer (March-June), Rainy (July–October), and winter (November-February) to study the response to variable climatic factors to the root colonization and spore density of mycorrhiza. To determine the significance of variations in AMF spore density and percentage root colonization during different seasons, one-way ANOVA was performed. Results showed that in all the sites maximum mean spore density was observed in the summer (March-June) season but in the case of percentage root colonization, the value was found maximum in the humid season (July-October) in the control site whereas, in the three experimental sites, the maximum root colonization was observed in summer season (march-June). Hence, it may be concluded that hot climatic condition is favourable for mycorrhizal spore formation and root colonization was also favoured by hot climate.

Systemic infection caused by the methicillin-resistant Staphylococcus aureus USA300-LV lineage in a Brazilian child previously colonized

ABSTRACT The methicillin-resistant Staphylococcus aureus (MRSA) USA300-Latin American variant (USA300-LV) lineage is well documented in northern Latin American countries. It has replaced established clones in hospital environments. We herein report a systemic infection caused by a USA300-LV isolate in a 15-year-old boy, from a low-income area of Rio de Janeiro, previously colonized by the same strain. During hospital stay, seven pvl-positive MRSA USA300-LV isolates were recovered by nasal swab, blood and abscess secretion. The patient underwent intravenous vancomycin, daptomycin, and oral sulfamethoxazole/trimethoprim, and was discharged after 45 days after full recovery. This is the first documented case of a community-acquired MRSA infection caused by the USA300-LV variant in Brazil in a previously colonized adolescent with no history of recent travel outside of Rio de Janeiro. The need for improved surveillance programs to detect MRSA colonization in order to control the spread of hypervirulent lineages among community and hospital settings is highlighted.

Research progress of intestinal microecological disorders caused by antibiotics and the treatment / 药学学报

There is a variety of gut microbiota in human body, which is closely associated with the health and disease. Normal gut microbiota can produce colonization resistance to pathogens. Antibiotics can affect the composition of gut microbiota and change the intestinal microenvironment, resulting in intestinal microecological disorders, which in turn cause intestinal pathogenic infections and other diseases. In this paper, the concept of intestinal microecology, the mechanism of intestinal colonization resistance, the effect of antibiotics on intestinal microecology, and the treatment methods were reviewed, aiming to provide the information for the rational use of antibiotics and the development of more effective treatment methods to maintain the stability of intestinal microecology.

Group B Streptococcal Colonization among Pregnant Women and Neonates in a Tertiary Care Hospital in South India

Objectives To assess the prevalence of maternal and neonatal group B Streptococcal colonization, incidence of neonatal systemic illness, and antibiotic sensitivity of isolates. Methods This prospective cohort study was conducted in a South Indian tertiary care hospital. Rectovaginal swabs from pregnant mothers at 360/7–376/7 wk gestation and throat and rectal swabs from their neonates at 48 h of age were collected. Presence of group B Streptococcus (GBS) was identifed by broth enrichment step, and traditional microbiologic methods and antibiotic sensitivity of isolates was noted. All mothers received intrapartum antibiotic prophylaxis (IAP). Culture-positive sepsis, clinical sepsis, pneumonia, meningitis, and urinary tract infection were defned as neonatal systemic illness. Neonates of colonized mothers were followed at 3 mo for late-onset sepsis. Results Of the 310 mothers, 40 were GBS colonized (prevalence: 12.9%; 95% CI 9.2%, 17.6%). None of the neonates were colonized. Maternal GBS colonization was signifcantly associated with premature rupture of membrane (RR - 2.93, 95% CI - 1.66–5.16) and neonatal systemic illness (RR - 2.78, 95% CI - 1.39–5.54). Positive correlation was noted between duration of IAP?4 h and neonatal illness and between maternal GBS colonization and Apgar at 1 min?4. Clindamycin resistance was noted in 20%. All neonates remained well at 3 mo follow-up. Conclusion High maternal colonization alerts the need for GBS screening in India. Clindamycin resistance among GBS isolates questions its efectiveness as alternative therapy in penicillin allergy.

Caesarian Vs Vaginal Delivery: From A Human Microbiota Perspective

The route of the birth delivery influences new born's health. Children born via Cesarean section are at increased risk of developing asthma, systemic connective tissue disorders, juvenile arthritis, inflammatory bowel disease, immune deficiencies and leukemia. Part of these diseases is believed to be related to maturation of neonatal immune system. During vaginal delivery, the contact with the maternal vaginal and intestinal flora is an important source for the start of the infant's colonisation. During Caesarean delivery, this direct contact is absent, and non-maternally derived environmental bacteria plays an important role for infant's gastro-intestinal colonisation. The primary function of microbial colonisation during the foetal period, intrapartum and after the birth is crucial in maturation and development of new-bornimmune system. This review supports the choice of the route of birth delivery and consequently favours a decrease in unnecessary Cesarean sections. It is crucial to provide this information to pregnant women and/or couples and health workers to make informed and educated decisions

A Colonização dos Corpos e dos Afetos pelo Capitalismo: Um Debate Necessário / The Colonization of Bodies and Affections for Capitalism: A Necessary Debate / La Colonización de los Cuerpos y el Afecto por el Capitalismo: Un Debate Necesario

O presente estudo teórico tem por objetivo problematizar uma prática consolidada no contemporâneo: o consumo. Longe de responder à satisfação de necessidades básicas, as práticas de consumo são engendradas por uma série de enquetes realizadas por áreas como o marketing, a publicidade e o design. Elas visam não apenas conhecer as expectativas dos consumidores, mas também incutir neles o prazer de consumir, valendo-se de elementos simbólicos, afetivos e subjetivos. A argumentação teórica deste estudo, pautada na Psicologia Social, percorre o seguinte trajeto: primeiro, busca-se compreender o processo de colonização pela via do consumo atentando para como elas incidem sobre os corpos e os afetos. Na sequência, é colocada em análise a complexa relação com o que chamamos de estrangeiro, que pode tomar contornos colonizadores, mas também engendrar outras sensibilidades e maneiras de se vincular ao mundo. Ao final do estudo constata-se o quanto o sujeito contemporâneo deixa-se colonizar pelas promessas midiáticas de felicidade, satisfação e prazer que são proclamadas de maneira idealizada nas campanhas publicitárias em favor do consumo. Isso coloca à Psicologia Social o desafio de dar visibilidade aos processos de colonização, analisando criticamente os efeitos estéticos, afetivos, econômicos e políticos gerados para a população e para o planeta.

The present theoretical study aims to analyze a consolidated practice in the contemporary: consumption. Far from responding to the satisfaction of basic needs, consumer practices are engendered through surveys conducted by areas such as marketing, advertising and design. They aim not only to know the expectations of consumers, but also to instill in them the pleasure of consuming, using symbolic, affective and subjective elements. The theoretical argumentation of this study, based on Social Psychology, follows the following path: first, we seek to understand the process of colonization through consumption by looking at how they affect bodies and affections. Next, the complex relationship with what we call the alien, which can take colonizing contours, but also engender other sensitivities and ways of linking to the world, is put into analysis. At the end of the study, it is verified how much the contemporary subject is colonized by the media promises of happiness, satisfaction and pleasure that are proclaimed in an idealized way in advertising campaigns in favor of consumption. This gives social psychology the challenge of giving visibility to colonization processes, critically analyzing the aesthetic, affective, economic and political effects generated for the population and for the planet.

El presente estudio teórico pretende problematizar una práctica consolidada en lo contemporáneo: el consumo. Lejos de responder a la satisfacción de las necesidades básicas, las prácticas de consumo se engendran a través de encuestas realizadas por áreas como el marketing, la publicidad y el diseño. Su objetivo no es solo conocer las expectativas de los consumidores, sino también inculcarles el placer de consumir, utilizando elementos simbólicos, afectivos y subjetivos. La argumentación teórica de este estudio, basada en la Psicología Social, sigue el siguiente camino: en primer lugar, busca comprender el proceso de colonización a través del consumo observando cómo afectan a los cuerpos y a las afecciones. A continuación, se analiza la compleja relación con lo que llamamos el extranjero, que puede tomar contornos colonizadores, pero también engendrar otras sensibilidades y formas de vincularse con el mundo. Al final del estudio, se verifica hasta qué punto el sujeto contemporáneo está colonizado por las promesas mediáticas de felicidad, satisfacción y placer que se proclaman de manera idealizada en las campañas publicitarias a favor del consumo. Esto pone a la Psicología Social el desafío de dar visibilidad a los procesos de colonización, analizando críticamente los efectos estéticos, afectivos, económicos y políticos generados para la población y para el planeta.

Descripción morfológica y caracterización molecular de los hongos asociados a la raíz de Masdevallia coccinea Linden ex Lindl / Morphological description and molecular characterization of fungi associated with the root of Masdevallia coccinea Linden ex Lindl

RESUMEN Masdevallia coccinea es una orquídea llamativa, endémica de Colombia, empleada en la generación de híbridos ornamentales con más de una década, clasificada como una especie en peligro de extinción. Entre las técnicas usadas para la propagación in vitro y ex situ de especies de la familia Orchidaceae, se estudia la simbiosis micorrízica, debido a que esta familia micoheterótrofa depende de una correlación con estos hongos para subsistir en las primeras etapas de desarrollo en estado silvestre. Con el objetivo de caracterizar e identificar los hongos asociados a las raíces de M. coccinea, se realizó un estudio histológico en raíces y, a partir de micropreparados, se caracterizó morfológicamente micro, macroscópica y molecularmente diez aislamientos. Se identificó a M. coccinea como una orquídea que presenta diferentes patrones de colonización micorrízicos y con posibles efectos endófitos de los géneros Aspergillus, Scopulariopsis, Trichoderma, Ilyonectria y del orden Xylariales en condiciones ex situ.

ABSTRACT Masdevallia coccinea is a striking orchid, endemic to Colombia, used in the generation of ornamental hybrids, with more than a decade classified as an endangered species. Among the techniques used for in vitro and ex situ propagation of species of the Orchidaceae family, mycorrhizal symbiosis is studied, because this mycoheterotrophic family depends on a correlation with these fungi to survive in the early stages of development in the wild. In order to characterize and identify the fungi associated with the roots of M. coccinea, a histological study was carried out on roots and 10 isolates were morphologically, macroscopically and molecularly characterized from micropreparations. M. coccinea is identified as an orchid with different mycorrhizal colonization patterns and with possible endophytic effects of the genera Aspergillus, Scopulariopsis, Trichoderma, Ilyonectria and the order Xylariales under ex situ conditions.

Health of the Newborn and Breastfeeding during the COVID-19 Pandemic: A Literature Review / Saúde do recém-nascido e amamentação durante a pandemia de COVID-19: Uma revisão da literatura

Abstract Objective The present article presents a literature review concerning the microbiota of breast milk and the influence of epigenetics in the susceptibility to COVID-19. Methods A literature review. Results Breastfeeding transfers microbiota, nutrients, diverse white blood cells, prebiotics, hormones, and antibodies to the baby, which provide short- and longterm immunological protection against several infectious, gastrointestinal, and respiratory illnesses. The little evidence available shows that breast milk very rarely carries the SARS-CoV-2 virus, and even in those cases, it has been discarded as the source of contagion. Conclusion The reviewed studies show evidence of a beneficial effect of breastfeeding and highlights its importance on the current pandemic due to the immune reinforcement that it provides. Breastfed individuals showed better clinical response due to the influence on the microbiota and to the nutritional and immune contribution provided by breast milk, compared with those who were not breastfed.

Resumo Objetivo O presente artigo apresenta uma revisão de literatura sobre amicrobiota do leite materno e a influência da epigenética na suscetibilidade à COVID-19. Métodos Revisão de literatura. Resultados A amamentação transfere microbiota, nutrientes, diversos glóbulos brancos, prebióticos, hormônios e anticorpos para o bebê, os quais proporcionam proteção imunológica de curto e longo prazo contra diversas doenças infecciosas, gastrointestinais e respiratórias. As poucas evidências disponíveis mostram que o leite materno transportamuito raramente o vírus SARS-CoV-2, emesmo nestes casos, ele foi descartado como fonte de contágio. Conclusão Os estudos revisados mostram evidências de um efeito benéfico da amamentação e destacam sua importância na atual pandemia devido ao reforço imunológico que ela proporciona. Os indivíduos amamentados mostraram melhor resposta clínica devido à influência sobre a microbiota, e à contribuição nutricional e imunológica proporcionada pelo leite materno, em comparação com aqueles que não o foram.

Distribuição de grupos folclóricos em Santa Catarina e sua relação com a colonização do Estado / Distribution of folkloric groups in Santa Catarina and its relation to the colonization of the State / Distribución de grupos folclóricos en Santa Catarina y su relación con la colonización del Estado

O objetivo foi verificar se o histórico de colonização das diferentes regiões de Santa Catarina se reflete na distribuição atual dos grupos folclóricos do estado. Os dados quantitativos foram retirados da listagem fornecida pela Fundação Catarinense de Cultura. Para as informações históricas, foi feita uma revisão bibliográfica. Estão registrados 182 grupos folclóricos distribuídos por 74 cidades. A etnia mais abundante foi a alemã, seguida pela luso-açoriana, e então italiana, gaúcha, de outros países europeus, grupos mistos, afrobrasileiros e outros. Os grupos luso-açorianos se concentram no litoral, o que concorda com o fato de terem sido responsáveis pela colonização mais antiga. Para os alemães e demais europeus, foram geograficamente observadas as duas principais ondas de imigração historicamente registradas: primeiro no nordeste e vale do Itajaí e posteriormente no oeste. Percebeu-se que a distribuição de grupos folclóricos de cada etnia tem relação com o processo de colonização das diferentes regiões.

The objective was to verify if the colonization history of different regions of Santa Catarina is reflected on the current distribution of the folkloric groups of the state. The quantitative data were taken from the list provided by the Fundação Catarinense de Cultura. For the historical information, a bibliographic review was done. There are 182 groups registered, distributed on 74 cities. The most abundant ethnicity was German, followed by Portuguese-Azorean, Italian, gaúcha, other European countries, mixed groups, African-brazilian and others. The Portuguese-Azorean groups concentrate on the coast, what agrees with the fact they were responsible for the oldest colonization. For the Germans and other Europeans, the two main colonization waves historically registered were geographically observed: first on the northeast and Itajaí's valley and after on the west. It was perceived that the distribution of the folkloric groups of each ethnicity is related to the colonization process of the different regions.

Los datos cuantitativos fueron tomados de la lista proporcionada por la Fundação Catarinense de Cultura. Para información histórica, se realizó una revisión bibliográfica. Hay 182 grupos folclóricos distribuidos en 74 ciudades. La etnia más abundante fue la alemana, seguida por la portuguesa-azoriana, italiana, gaucha, otros países europeos, grupos mixtos, afrobrasileños y otros. Los grupos luso-azoreanos se concentran en la costa, lo que concuerda con el hecho de que fueron los responsables de la colonización más antigua. Para los alemanes y otros europeos, se observaron geográficamente las principales olas de inmigración registradas: en el noreste, el valle de Itajaí el oeste. Se notó que la distribución de los grupos folclóricos de cada etnia está relacionada con el proceso de colonización de las regiones.

Riesgo de infección en pacientes oncológicos colonizados por bacterias productoras de p-lactamasas de espectro extendido y enterobacterias productoras de carbapenemasas / Risk of infection in cancer patients colonized by extended expectrum p-lactamases and carbapenem producing Enterobacteriaceae

INTRODUCCIÓN: La prevalencia de microorganismos multirresistentes es un problema de salud pública que continúa creciendo a lo largo del mundo. Existe una población principalmente susceptible de ser colonizada y posteriormente infectarse, son los pacientes oncológicos. OBJETIVO: Identificar las características clínicas y patológicas de los pacientes oncológicos y su relación con la infección con microorganismos productores de BLEE y EPC. PACIENTES Y MÉTODOS: Se condujo un estudio retrospectivo y de carácter analítico entre el primero de enero de 2019 y el 30 de junio de 2020 en tres unidades hemato-oncológicas. RESULTADOS: Incluyó a 3.315 pacientes, de los cuales 217 (6,5%) se encontraban colonizados por microorganismos productores de BLEE y EPC; de éstos, 106/217 (48,8%) presentaron al menos un episodio de infección. El microorganismo más frecuentemente aislado fue Klebsiella pneumoniae, en 29/106 (27,4%). De los infectados, 18/106 (17%) presentaron infección por el mismo microorganismo colonizador. La mucositis (p = 0,002), edad mayor a 65 años (p = 0,041), hipoalbuminemia (p < 0,01), neutropenia (p < 0,01) y la presencia dispositivos invasivos (p < 0,01) demostraron una relación con el desarrollo de infección. CONCLUSIÓN: La presencia de hipoalbuminemia (OR 3,3, IC 1,5-7,1, p < 0,01), dispositivos invasivos (OR 5,8, IC 3.0-11,4, p < 0,01) y neutropenia (OR 4,1, IC 1,5-11,4, p < 0,01) predicen el desarrollo de infecciones.

BACKGROUND: The prevalence of multi-resistant microorganisms is a public health problem that continues to grow globally. There is a population that is mainly susceptible to being colonized and subsequently infected, and these are cancer patients. AIM: To identify the clinical and pathological characteristics of cancer patients and their relationship with infection with ESBL and CPE producing microorganisms. METHODS: A retrospective and analytical study was conducted between January 1, 2019 and June 30, 2020 in three hematooncological units. RESULTS: We included 3315 patients of which 217 (6.5%) were colonized by microorganisms producing ESBL and CPE. Of these, 106/217 (48.8%) had at least one episode of infection. The most frequently isolated microorganism was Klebsiella pneumoniae 29/106 (27.4%). Of those infected, 18/106 (17%) presented infection by the same colonizing microorganism. Mucositis (p = 0.002), age over 65 years (p = 0.041), hypoalbuminemia (p < 0.01), neutropenia (p < 0.01) and the presence of invasive devices (p < 0.01) demonstrated a relationship with development of infection. The presence of hypoalbuminemia (OR 3.3, CI 1.5-7.1, P < 0.01), invasive devices (OR 5.8, CI 3.0-11.4, p < 0.01) and neutropenia (OR 4.1, CI 1.5-11.4, p < 0.01) predict the development of infections.

Clinical Profile of Children With Cystic Fibrosis Surviving Through Adolescence and Beyond

Objective: To document morbidities in adolescents with cystic fibrosis (CF) from India. Methods: Details of children with cystic fibrosis surviving beyond 15 years of age were extracted from hospital records, and analyzed. Results: 43 children [Median (IQR) age 18.7 (17, 20.6) years, were enrolled. Median (IQR) body mass index was 15.82 (13.5, 19.05) kg/m2. Pseudomonas species were isolated from respiratory specimens of 34 (79%) adolescents. Allergic bronchopulmonary aspergillosis (ABPA) and Cystic fibrosis-related diabetes (CFRD) were seen in 12 (28%) and 11 (26%) patients, respectively. Conjugated hyperbilirubinemia and distal intestinal obstruction syndrome (DIOS) were diagnosed in 15 (35%) and 6 (14%) children, respectively. Pseudomonas species colonization (P=0.04) and multiple pulmonary exacerbations in last one year (P<0.001) were significant predictors of FEV1% predicted. Conclusion: Malnutrition, chronic airway colonization, ABPA, CFRD, conjugated hyperbilirubinemia and DIOS are morbidities observed in adolescents with CF in India. The data support the need for early screening of CF-associated morbidities.

As subjetividades periféricas e os impasses para a descolonização da clínica psicológica / Peripheral subjectivities and the challenges for decolonizing psychological clinic / Las subjetividades periféricas y los obstáculos a la descolonización de la clínica psicológica

Pode a clínica psicológica escutar as subjetividades periféricas? A partir dessa problematização, o presente estudo teórico se propõe a pensar a relação entre clínicas psicológicas e subjetividades periféricas, aquelas vidas que estão afastadas dos diversos centros: políticos, sociais, econômicos, étnico-raciais, de gênero e sexualidades etc. Marcadas por relações de exclusão, opressões e precarizações, as subjetividades periféricas são vistas como produtos de processos de colonização que se atualizam em estratégias mais sofisticadas, investindo além do corpo biológico e alcançando os processos de subjetivação em suas múltiplas faces. Ao mesmo tempo, também são vistas como sujeitas, cujos processos de dessubjetivação dessa produção de território existencial terrificante expressam linhas de resistência crítica e inventiva que contornam um espaço fora do centro não como lugar de sujeição, mas de politização do corpo e afirmação da vida. O estudo aponta para a irrupção da fixidez teórico-metodológica e aposta na invenção de uma clínica que pensa a partir de onde os pés pisam, e da experimentação dos contextos e das vidas que se propõe cuidar, produzindo uma dupla tarefa de descolonização: da psicologia clínica ainda carregada de discursos e práticas colonizantes e das subjetividades que são produtoras e produtos de processos de opressão e exclusão.(AU)

Can psychological clinic listen to peripheral subjectivities? From this problematic, this theoretical study reflects on the relationship between psychological clinics and peripheral subjectivities-lives that are removed from the various centers: political, social, economic, racial-ethnic, gender and sexualities, etc. Marked by exclusion, oppression, and precariousness, peripheral subjectivities are seen as products of colonization processes that are reiterated by more sophisticated strategies, going beyond the biological body and reaching the subjectivation processes in its multiple facets. Simultaneously, they are seen as subjects, whose desubjectivation processes of this terrifying existential territory production express critical and inventive resistances that outline a peri-space not as a place of subjection, but of politicization of the body and affirmation of life. The study argues in favor of dismantling theoretical-methodological fixity and inventing a clinic rooted on experimentation of the contexts and lives it proposes to care for, engendering a double decolonization: of clinical psychology still laden with colonizing discourses and practices and of subjectivities that produce and are products of oppression and exclusion.(AU)

¿Puede la clínica psicológica escuchar las subjetividades periféricas? Desde esta problematización, este estudio se propone pensar la relación entre clínicas psicológicas y subjetividades periféricas, aquellas vidas que están apartadas de todos los centros: políticos, sociales, económicos, étnico-raciales, de género y sexualidades, etc. Marcadas por relaciones de exclusión, opresiones, precarizaciones, estas subjetividades periféricas son producto de los procesos de colonización que se actualizan en estrategias más sofisticadas que, más allá del cuerpo biológico, invisten en los procesos de subjetivación y sus múltiplos rostros. Al mismo tiempo, son agentes cuyos procesos de subjetivación de esta producción de territorio existencial petrificante exprimen líneas de resistencia crítica e inventiva que contornan el margen del centro no como espacio de sujeción, sino como espacio de politización del cuerpo y afirmación de la vida. El estudio realizado apunta a la necesidad de ruptura con los aportes teórico-metodológicos rígidos y apuesta en la invención de una clínica que piensa desde su fundamentación, y de la experimentación de los contextos y vidas que buscan cuidar, lo que produce una doble tarea de descolonización: de la psicología clínica aún marcada por las prácticas de colonialidad y de las subjetividades que son productoras y producto de los procesos de opresión y exclusión.(AU)

Effect of using forced and free oviposition methods to obtain eggs and larvae of Mansonia (Diptera: Culicidae) females from Rondonia, Brazil (western Amazon)

ABSTRACT Species of the genus Mansonia Blanchard are disease pathogen vectors in some regions of the world and can cause considerable inconvenience due to their bites when present in high numbers. However, little is known regarding their biology in Brazil. The objective of this work was to investigate some reproductive parameters of Mansonia from the western Brazilian Amazon. Females were captured in the field using human landing catches in rural areas of Porto Velho, Rondonia, Brazil. The mosquitoes were identified and separated into two groups for oviposition: forced, i.e., with wing removal, and free oviposition, without wing removal. Daily observations of oviposition and female survival were conducted until oviposition. The eggs and subsequent larvae were counted for fecundity and fertility evaluation, respectively. The species collected in this study were Mansonia amazonensis (Theobald), Mansonia humeralis Dyar & Knab and Mansonia titillans (Walker). The oviposition percentage for Ma. amazonensis was much lower than for Ma. humeralis and Ma. titillans. Forced oviposition resulted in a higher number of ovipositing females only for Ma. humeralis. Fecundity and fertility were not affected by the oviposition method. Egg and larval numbers were generally lower for Ma. amazonensis compared with the other species. Forced oviposition may be a tool to increase the number of ovipositing females depending on the Mansonia species studied in order to establish colonies in the laboratory.

The Potential Effects of Fungicides on Association of Rhizophagus irregularis with Maize and Wheat

Abstract The effect of different fungicides on mycorrhizal fungi should be investigated in different plants and environmental conditions. Thus, the purpose of this study was to appraise the effect of simultaneous fungicides application (including benomyl, rovral TS, mancozeb, and tilt) on the efficiency of Rhizophagus irregularis in cultivations of maize and wheat. This study was conducted in two separate experiments in the laboratory and greenhouse. The results of the laboratory stage showed that the use of all four fungicides significantly reduced the spore number compared to the conditions of non-use of the fungicide, although only rovral TS and mancozeb led to a significant reduction in root colonization percentage of R. irregularis. In the greenhouse, the benomyl significantly increased root dry weight in maize although tilt significantly reduced root colonization of maize with R. irregularis. The tilt and rovral TS had a positive effect and benomyl had a negative effect on wheat growth traits, but the root colonization of wheat with R. irregularis was not affected by fungicides. Generally, benomyl (2 g L-1) in maize and tilt (2 mL L-1) in wheat and rovral TS in both plants could be recommended with the combined application of R. irregularis inoculants. Therefore, depending on the type of fungicide and the host plant, the effect of the fungicide on colonization and association of mycorrhiza varies.

Expression of virulence genes in Group B Streptococcus isolated from symptomatic pregnant women with term and preterm delivery

Aims@#Maternal vaginal Group B Streptococcus (GBS) colonization is considered a risk factor for preterm delivery and, consequently, neonatal infections. Previous studies have portrayed the important roles of these virulence factors, including hemolytic pigment, hyaluronidase (HylB), serine-rich protein (Srr) and bacterial surface adhesion of GBS (BsaB) in mediating GBS colonization and intrauterine ascending infection, causing preterm delivery. This study aimed to investigate the association between mRNA expression of virulence genes in GBS isolates obtained from symptomatic pregnant women and preterm delivery.@*Methodology and results@#GBS isolates were obtained from high vaginal swabs of 40 symptomatic pregnant women of gestational age of less than 37 weeks. RNA was extracted from these GBS isolates and RT-qPCR was performed to determine the relative mRNA expression of GBS virulence genes, including CylE (encode enzyme required for the biosynthesis of the hemolytic pigment), HylB, Srr-1 and BsaB. Socio-demographic details and obstetric history were not found to be associated with the delivery outcomes of these women. The GBS isolates from symptomatic pregnant women who delivered prematurely showed a higher expression of CylE gene and a trend towards an elevated expression of HylB gene compared to women with term delivery. Meanwhile the expression of both Srr-1 and BsaB genes was similar between symptomatic pregnant women who had term or preterm delivery.@*Conclusion, significance and impact of study@#The results suggest that following vaginal colonization, both CylE and HylB genes are likely to contribute to intrauterine ascending infection and inflammation, leading to preterm delivery in humans. These virulence factors may be targeted for the pre-clinical stages of vaccine development or therapeutic intervention.

Prevalence and antimycotic susceptibility profile of Candida species in the oral cavities of HIV/AIDS patients and pregnant women in Nsukka, Nigeria

Aims@#The present study determined Candida species occurrence in the mouth of HIV/AIDS, pregnant women and healthy individuals, and Candida susceptibility to antimycotics.@*Methodology and results@#A cross-sectional study of the Candida species occurrence and their in vitro sensitivity to nystatin, clotrimazole, ketoconazole and fluconazole was studied. Oral swabs were taken from the dorsum of the tongue of 63 HIV/AIDS patients, 38 pregnant women and 53 apparently healthy humans served as control. All participants gave their consent. The samples were cultured for isolation of Candida species. The susceptibility of commonly used antimycotics against Candida species was determined using agar-well and disc-diffusion methods. The broth dilution method was adopted in the determination of the minimum inhibitory concentration of the drugs. The rate of Candida species colonization in HIV/AIDS patients was higher than that among pregnant women and apparently healthy humans. Candida albicans had the highest frequency. Candida species displayed higher sensitivity to nystatin and clotrimazole than ketoconazole and fluconazole. Candida albicans exhibiting low sensitivity to fluconazole were found in the mouth of AIDS patients, pregnant women and apparently healthy humans.@*Conclusion, significance and impact of study@#Candida species prevalence was highest among HIV patients. Candida albicans had the highest frequency among the study groups and had reduced susceptibility to fluconazole. The findings of the study underscore the need for regular surveillance and susceptibility testing of Candida isolates before prescription of antimycotics, especially in cases of chronic infection, as well as the development of safe and efficacious treatment alternatives since Candida isolates are becoming less susceptible to fluconazole.

The effect of different ultrasound debridement method on epiphytic bacteria of diabetic foot ulcer wound / 中国实用护理杂志

Objective:To investigate the effect of ultrasonic debridement mediated by 0.9% sodium chloride solution and 0.5% iodophor volt combined with eddy current washing and high pressure pulse washing on the removal of colonized bacteria on the wound surface of diabetic foot and wound healing.Methods:From March to November 2020, a total of 60 patients using ultrasonic therapy for debridement were divided into control group, experimental group 1, experimental group 2 and experimental group 3 by random digit table in the fourth People′s Hospital of Dalian. The final effective data collected was 15 cases in each group. The control group was given ultrasonic debridement mediated by 0.9% sodium chloride solution and eddy current washing.Experimental group 1 was given ultrasonic debridement mediated by 0.9% sodium chloride solution and high pressure pulse washing. Experimental group 2 received 0.5% iodophor mediated ultrasonic debridement and eddy current washing. Experimental group 3 0.5% iodophor mediated ultrasonic debridement and high pressure pulse washing. The size of the wound was measured, sampled and bacterial cultured before and after the first, fifth and 10th intervention. The wound bacterial clearance rate and wound area reduction rate were calculated and compared.Results:Before and after 3 interventions, the bacterial clearance rate and the total reduction of wound surface in 4 groups were increased ( P<0.01), the total bacterial clearance rate of experimental group 3 was the highest, which was (93.85 ± 9.87)%.The total reduction rate of wound in experimental group 2 was the highest, which was (20.831 4 ± 9.379 8)%. Conclusions:0.5% iodophor mediated ultrasonic debridement combined with high pressure pulse washing is the most effective way in the removal of diabetic foot wounds, and 0.5% iodophor solution mediated ultrasonic debridement combined with eddy current washing is the most effective in reducing diabetic foot wounds.
