ABSTRACT

Introducción: La sarcoidosis es una enfermedad inflamatoria, granulomatosa de etiología desconocida. Puede afectar cualquier órgano siendo la afectación pulmonar la más frecuente. La piel se compromete en aproximadamente 30% de los casos, pudiendo ser inicial o único. La sarcoidosis es muy rara en el Paraguay. Objetivos: Realizar una revisión de los casos de sarcoidosis observados en el Servicio de Dermatología del Hospital Nacional en el periodo 2010-2020; determinando sus características demográficas, clínicas, laboratoriales y evolutivas. Materiales y métodos: Estudio retrospectivo, descriptivo y observacional. Resultados: Se diagnosticaron 5 casos, todas mujeres de raza blanca, con edades que oscilaban de 41 a 63 años. Las formas clínicas fueron papulosa en 3 casos, en placa 1 y mixta 1. Las lesiones cutáneas eran asintomáticas y estaban ubicadas preferentemente en rostro (4 casos). El compromiso sistémico se objetivó en las primeras consultas en 2 casos (pulmonar, ocular y ganglionar en 1 y del aparato lagrimal en otro). En todos los casos el diagnóstico se fundamentó en la correlación clínico-histológica, con el hallazgo de los granulomas sarcoides. Todos recibieron clobetasol tópico, 3 pacientes ciclos de prednisona y 2 hidroxicloroquina. La evolución fue favorable en 3 casos y 2 no volvieron a sus controles. Conclusión: La sarcoidosis con manifestaciones cutáneas es rara en nuestro Servicio, pero representa un desafío diagnóstico, que debe ser oportuno para diferenciarla de otras patologías más prevalentes en nuestro medio


Introduction: Sarcoidosis is an inflammatory, granulomatous disease of unknown etiology. It can affect any organ, lung involvement being the most frequent. The skin is compromised in approximately 30% of the cases, and can be initial or unique. Sarcoidosis is very rare in Paraguay. Objectives: To carry out a review of the sarcoidosis cases observed in the Dermatology Service of the National Hospital in the period 2010-2020; determining their demographic, clinical, laboratory and evolutionary characteristics. Materials and methods: Retrospective, descriptive and observational study. Results: 5 cases were diagnosed; all white women; with ages ranging from 41 to 63 years. The clinical forms were papular in 3 cases, in plate 1 and mixed 1. The skin lesions were asymptomatic and were preferably located on the face (4 cases). Systemic involvement was observed in the first consultations in 2 cases (pulmonary, ocular and lymph node in 1 and the lacrimal apparatus in another). In all cases the diagnosis was based on the clinical-histological correlation, with the finding of sarcoid granulomas. All received topical clobetasol, 3 patients received prednisone cycles and 2 hydroxychloroquine. The evolution was favorable in 3 cases and 2 did not return to their controls. Conclusion: Sarcoidosis with skin manifestations is rare in our Service, but it represents a diagnostic challenge that must be timely to differentiate it from other more prevalent pathologies in our setting

ABSTRACT

Introducción. Los patrones de susceptibilidad antimicrobiana de Salmonella enterica serotipo Typhi se han modificado globalmente durante las últimas tres décadas. Objetivo. Describir los patrones de susceptibilidad antimicrobiana de las cepas de Salmonella enterica Typhi, aisladas en El Salvador de enero 2017 a junio 2020. Metodología. Evaluación secundaria de las bases de datos del Laboratorio Nacional de Salud Pública, de los aislamientos de Salmonella enterica Typhi con sus respectivos antibiogramas, de muestras de pacientes que adolecieron de fiebre tifoidea en El Salvador, de enero 2017 a junio 2020. Resultados. 1406 aislamientos de Salmonella enterica Typhi fueron reportados. El 100 % de los aislamientos analizados presentó susceptibilidad a la ceftriaxona y a la azitromicina. El 99,9 % de los aislamientos analizados presentó susceptibilidad a la ampicilina, al cloranfenicol, a la tetraciclina y al trimetoprim-sulfametoxazol. Para ciprofloxacina, se detectó susceptibilidad en el 8,5% de las cepas analizadas, susceptibilidad intermedia en el 91,5% y resistencia en el 0,08 %. Conclusión. Los hallazgos son compatibles con lo reportado a nivel mundial: el desarrollo rápido de susceptibilidad intermedia o resistencia a la ciprofloxacina, una vez esta es adoptada como el tratamiento de elección para la fiebre tifoidea. En El Salvador, los antibióticos antes considerados como de primera línea contra Salmonella enterica Typhi, deben ser reciclados


Introduction. The antimicrobial susceptibility patterns of Salmonella enterica serotype Typhi have been modified globally for the past three decades. Target. Describe the antimicrobial susceptibility patterns of Salmonella enterica Typhi strains, isolated in El Salvador from January 2017 to June 2020. Methodology. Secondary assessment from the databases of the National Public Health Laboratory, of the isolates of Salmonella enterica Typhi with their respective antibiograms, of samples of patients who suffered from typhoid fever in El Salvador, from January 2017 to June 2020. Results. 1406 isolates of Salmonella enterica Typhi were reported. 100% of the isolations analyzed showed susceptibility to ceftriaxone and azithromycin. 99.9% of the isolates analyzed presented susceptibility to ampicillin, chloramphenicol, tetracycline, and trimethoprim-sulfamethoxazole. For ciprofloxacin, detected susceptibility in 8.5% of the strains analyzed, intermediate susceptibility in 91.5% and resistance in the 0.08%. Conclution. The findings are consistent with what has been reported worldwide: the rapid development of susceptibility intermediate or resistance to ciprofloxacin, once it is adopted as the treatment of choice for typhoid fever. In El Salvador, antibiotics previously considered first-line against Salmonella enterica Typhi, must be recycled

ABSTRACT

Abstract The airborne spread is the main route of human-to-human transmission of coronavirus, including he SARS CoV-2 virus causing the disease known as COVID-19. The implicit risk of aerosolization of SARS CoV-2 infective microdroplets while carrying out respiratory function tests has caused a significant limitation of activity in most Pulmonary Function Laboratories since the beginning of the pandemic. This document aims to update the recommendations for the management of Pulmonary Function Laboratories in the context of the COVID-19 outbreak in Argentina. New recommendations include ways to carry out pulmonary function testing during the context of a high and low community viral spread phase, the evaluation of post-COVID-19 patients, as well as several aspects of biosafety for patients and operators. Measures consist of promoting air circulation in the environment, the use of antimicrobial filters, the protection of airways and mucous membranes, and hand washing.


Resumen La diseminación aerógena del virus SARS CoV-2 es la principal forma de transmisión interhumana de este coronavirus causante de la enfermedad conocida como COVID-19. El riesgo implícito de la aerosolización de microgotas infectantes del SARS CoV-2 durante la ejecución de las pruebas funcionales respiratorias ha provocado una importante limitación de la actividad en la mayoría de los laboratorios de función pul monar desde el inicio de la pandemia. Este documento tiene por objetivo actualizar las recomendaciones para el manejo del laboratorio de función pulmonar en el contexto de la epidemia COVID-19 en Argentina. Se incorporan nuevas recomendaciones para realizar pruebas funcionales respiratorias en el contexto de una fase alta y baja de circulación viral comunitaria, para pacientes post COVID-19, así como para la bio seguridad de pacientes y operadores. Las medidas incluyen la ventilación del ambiente, el uso de filtros antimicrobianos, la protección de vía área y mucosas y el lavado de manos.

ABSTRACT

Introducción: La selección de exámenes laboratorios preoperatorios (test específicos o exámenes por imágenes) debe hacerse como medida complementaria en el caso de sospecha clínica. La solicitud indiscriminada y de rutina es innecesaria e implica costos adicionales para la institución, además de la posibilidad de resultados falsos positivos, con repercusiones más o menos graves para los pacientes. Objetivo: Destacar los resultados y la repercusión clínico-anestésica de los exámenes complementarios preoperatorios en pacientes ASA I para cirugía ambulatoria que llegan a cirugía ambulatoria en el Hospital General Docente Comandante Pinares del municipio de San Cristóbal, Artemisa durante el año 2017. Método: Se realizó un estudio observacional de tipo descriptivo, de corte transversal en el Hospital General Docente Comandante Pinares del municipio de San Cristóbal, Artemisa, durante el año 2017. El universo se representa por 823 pacientes que se sometieron a cirugía ambulatoria, la muestra fue de 394 pacientes, según criterio de selección no probabilístico, intencional. Resultados: El sexo con mayor predominio en las cirugías fue el femenino 65,98 por ciento, las edades más frecuentes fue de 18-30 años. La cirugía electiva que más se realizó fue la colecistectomía 43,18 por ciento. En cuanto a los exámenes paraclínicos realizados, se detectó una baja incidencia de alteraciones, la complicación perioperatoria detectada fue la crisis hipertensiva 0,50 por ciento. Conclusión: Los resultados de los exámenes complementarios fueron normal en la mayoría de los pacientes, sin repercusiones o cambios en la conducta clínico anestésica. Además, generaron un elevado gasto a la institución de salud(AU)


Introduction: The selection of preoperative laboratory tests (specific tests or imaging tests) should be done, as a complementary measure, in the case of clinical suspicion. Indiscriminate and routine request is unnecessary and implies additional costs for the institution, in addition to the possibility of false positive results, with more or less serious repercussions for patients. Objective: To highlight the results and the clinical-anesthetic repercussion of complementary preoperative examinations in ASA-I patients who arrive for ambulatory surgery at Commandant Pinares General Teaching Hospital in San Cristóbal Municipality, Artemisa Province, during the year 2017. Method: An observational, descriptive, cross-sectional study was carried out at Commandant Pinares General Teaching Hospital in San Cristóbal Municipality, Artemisa Province, during the year 2017. The universe was represented by 823 patients who underwent ambulatory surgery. The sample consisted of 394 patients, following nonprobabilistic, intentional selection criteria. Results: The sex with the highest prevalence of surgeries was the female sex (65.98 percent). The most frequent ages were between 18 and 30 years. The most performed elective surgery was cholecystectomy (43.18 percent). Regarding the paraclinical examinations performed, a low incidence of alterations was detected; the perioperative complication detected was hypertensive crisis (0.50 percent). Conclusion: The results of the complementary examinations were normal in most of the patients, without repercussions or changes in the clinical anesthetic behavior. In addition, they generated high expenses for the health institution(AU)

ABSTRACT

Resumen La tuberculosis es una enfermedad de importancia en la salud pública a nivel mundial, con una alta incidencia a nivel del territorio colombiano. Principalmente, afecta el parénquima pulmonar; sin embargo, en un porcentaje elevado de casos se diagnostica en su forma extrapulmonar y el tracto gastrointestinal es uno de los sitios más frecuentes. Así mismo, la región ileocecal y el íleon terminal son las regiones con más predilección por la bacteria Mycobaterium tuberculosis. Las manifestaciones en esta rara presentación de la enfermedad están dadas por dolor abdominal y sensación de masa principalmente, lesiones ulcerosas en la mucosa intestinal y hallazgos histológicos correspondientes a granulomas caseificantes de gran tamaño y de morfología confluente, que se diferencian de otras entidades como la enfermedad de Crohn. La búsqueda de la enfermedad dentro del tracto gastrointestinal se realiza con ayuda de métodos invasivos como la colonoscopia y de ayudas diagnósticas de laboratorio como cultivos, tinciones o reacción en cadena de la polimerasa (PCR). Dada la complejidad en el diagnóstico de esta forma de tuberculosis, el conocimiento y la manera en que se aborda un paciente con un cuadro sugestivo de esta enfermedad son factores importantes para establecer el manejo terapéutico oportuno. Se comparte un caso inusual de tuberculosis ileocecal como manifestación de síndrome febril prolongado con desenlace fatal.


Abstract Tuberculosis is a disease of public health importance worldwide with a high incidence in Colombia. It mainly affects the lung parenchyma. However, in a large number of cases, it is diagnosed in its extrapulmonary form, with the gastrointestinal tract being one of the most frequent sites. Mycobacterium tuberculosis has a strong predilection for the ileocecal region and the terminal ileum. Manifestations of this rare form of the disease are abdominal pain and mass sensation mainly, as well as ulcerative lesions in the intestinal mucosa and histological findings corresponding to large caseating granulomas of confluent morphology, which distinguish it from other entities such as Crohn's disease. Invasive procedures, such as colonoscopy, and diagnostic laboratory aids, such as cultures, stains, and PCR, are used to find the disease in the gastrointestinal tract. Given the difficulty of diagnosing this type of tuberculosis, knowledge and how a patient with symptoms suggestive of the disease is approached are critical factors for establishing timely treatment. The following is an unusual case of ileocecal TB as a manifestation of prolonged febrile illness with a fatal outcome.

ABSTRACT

A Covid-19 é uma doença infecciosa causada pelo novo coronavírus, denominado SARS-CoV-2, que causou um surto de pneumonia viral incomum em pacientes em Wuhan, na China, no final do ano de 2019. O vírus se disseminou pelo mundo em grandes proporções, atingindo o status epidemiológico de pandemia. Diante desse cenário, que afetou toda a Federação brasileira, o Laboratório Central de Saúde Pública Professor Gonçalo Moniz (Lacen-BA) tem exercido papel fundamental no diagnóstico da Covid-19 e na vigilância genômica do SARS-CoV-2. Nesse sentido, este estudo tem como objetivo descrever as estratégias implementadas pelo Lacen-BA para ampliar a capacidade diagnóstica e atender a demanda da rede SUS-BA no contexto da pandemia da Covid-19. Trata-se de um estudo descritivo-observacional, orientado por um modelo lógico sustentado em quatro dimensões: parque tecnológico, metodologias analíticas, descentralização do exame e monitoramento de indicadores de resultados. As iniciativas de gestão possibilitaram ampliação da capacidade instalada e operacional, mediante modernização da estrutura física, renovação do parque tecnológico, reorganização dos fluxos e processos de trabalho, aporte de novas tecnologias analíticas e estruturação de dashboard para monitorar indicadores e subsidiar o processo decisório. O Lacen-BA, enquanto coordenador da Rede Estadual de Laboratórios de Saúde Pública e sistema de apoio da Rede de Atenção à Saúde (RAS), constitui-se então em estruturas policêntricas essenciais para o diagnóstico descentralizado e regionalizado da Covid-19, contribuindo para a integração sistêmica das ações e serviços no contexto da regionalização da saúde, de modo a garantir a universalidade do acesso e integralidade dos cuidados aos usuários do SUS.


Covid-19 is an infectious disease caused by the new coronavirus, called SARS-CoV-2, which caused an outbreak of unusual viral pneumonia in patients in Wuhan, China, at the end of 2019 and spread across the world, in large proportions, reaching the epidemiological status of a pandemic. Considering this epidemiological scenario that affected the entire Brazilian Federation, the Central Laboratory of Public Health Professor Gonçalo Moniz (Lacen-BA) has played a fundamental role in the diagnosis of Covid-19 and the genomic surveillance of SARS-CoV-2. In this sense, this study aims at describing the strategies implemented by Lacen-BA to expand the diagnostic capacity to meet the demand of the SUS-BA network, in the context of the Covid-19 pandemic. This is a descriptive-observational study, guided by a logical model based on four dimensions: technological park, analytical methodologies, decentralization of the exam and monitoring of result indicators. The management initiatives enabled the expansion of the installed and operational capacity by modernizing the physical structure, renewing the technological park, reorganizing workflows and processes, providing new analytical technologies, structuring the dashboard to monitor indicators and support the decision-making process. The Lacen-BA, as coordinator of the State Public Health Laboratory Network and support system of the Health Care Network (RAS), constitutes essential polycentric structures for the decentralized and regionalized diagnosis of Covid-19, which can contribute to the systemic integration of actions and services in the context of regionalization of health to guarantee the universality of access and comprehensive care to SUS users.


El covid-19 es una enfermedad infecciosa causada por el nuevo coronavirus, llamado SARS-CoV-2, que provocó un brote de neumonía viral inusual en pacientes en Wuhan, China, a fines de 2019, y que se extendió por el mundo, en grandes proporciones hasta alcanzar el estado epidemiológico de pandemia. Ante este escenario epidemiológico que afectó a Brasil, el Laboratorio Central de Salud Pública Profesor Gonçalo Moniz (Lacen-BA) ha jugado un papel fundamental en el diagnóstico del covid-19 y la vigilancia genómica del SARS-CoV-2. En este sentido, este estudio tiene como objetivo describir las estrategias implementadas por Lacen-BA para ampliar la capacidad de diagnóstico y atender la demanda de la red SUS-BA, en el contexto de la pandemia del Covid-19. Este estudio es descriptivo-observacional, guiado por un modelo lógico con base en cuatro dimensiones: parque tecnológico, metodologías analíticas, descentralización del examen y seguimiento de indicadores de resultado. Las iniciativas de gestión permitieron ampliar la capacidad instalada y operativa al modernizar la estructura física, renovar el parque tecnológico, reorganizar los flujos y procesos de trabajo, brindar nuevas tecnologías analíticas y estructuración del cuadro de mando para monitorear indicadores, y apoyar la toma de decisiones. Lacen-BA, como coordinador de la Red Estadual de Laboratorios de Salud Pública y sistema de apoyo de la Red de Atención a la Salud (RAS), constituye estructuras policéntricas imprescindibles para el diagnóstico descentralizado y regionalizado del Covid-19, que pueden contribuir a la integración sistémica de acciones y servicios en el contexto de la regionalización de la salud, a fin de garantizar la universalidad del acceso y la atención integral a los usuarios del SUS.

ABSTRACT

A pandemia da Covid-19 tem se apresentado como um dos maiores desafios sanitários desse século. Em dezembro de 2019, na China, o agente etiológico foi identificado como um novo coronavírus, nomeado SARS-CoV-2. No Brasil, o primeiro caso confirmado da Covid-19 ocorreu em fevereiro de 2020 e, no mês seguinte, a Secretaria da Saúde do Estado da Bahia (Sesab) confirmou o primeiro caso na Bahia.O Laboratório Central de Saúde Pública Prof. Gonçalo Moniz (Lacen-BA) centralizou o diagnóstico laboratorial para confirmação dos casos suspeitos de Covid-19 dos 417 municípios baianos, utilizando a técnica de RT-PCR. Este estudo tem como objetivo identificar e analisar as não conformidades das amostras suspeitas de Covid-19 encaminhadas ao Lacen-BA. Trata-se de um estudo descritivo, cujos dados foram obtidos por meio de consulta aos relatórios de amostras e exames em desacordo, disponíveis no sistema Gerenciador de Ambiente Laboratorial (GAL), gerados mensalmente, no período de abril a outubro de 2020. Para garantir a qualidade das amostras recebidas, foram definidos critérios de aceitação/rejeição de amostras e criado o formulário de notificação de não conformidades, assegurando a rastreabilidade das amostras de Covid-19. Através de relatórios diários do sistema GAL, selecionou-se os nove principais motivos de não conformidades, sendo o mais frequente "requisição cancelada pela gerência do GAL devido à expiração do prazo de triagem", com 72,8% dos registros. A inserção da padronização de processos na etapa pré-analítica permite trabalhar com segurança, garantindo a qualidade da amostra a ser processada e, consequentemente, um resultado fidedigno, dentro do prazo acordado.


The Covid-19 pandemic is one of the greatest health challenges of this century. In December 2019, in China, the etiologic agent was identified as a new coronavirus, named SARS-CoV-2. In Brazil, the first case of Covid-19 was confirmed in February 2020 and, in the following month, the Department of Health of the State of Bahia (Sesab) confirms the first case in the state. The Central Public Health Laboratory Prof. Gonçalo Moniz (Lacen/BA) centralized the laboratory diagnosis to confirm the suspected cases of Covid-19 of the 417 municipalities of the state, using the RT-PCR technique. This study aims at identifying and analyzing the non-conformities of the suspected samples of Covid-19 sent to Lacen-BA. This is a descriptive study whose data were obtained by consulting there reports of samples and exams in disagreement, available in the Laboratory Environment Manager (GAL) system, generated monthly, from April to October,2020. To guarantee the quality of the samples received, acceptance / rejection criteria for the samples were defined and a form for the notification of non-conformities was created, ensuring the traceability of the Covid-19 samples. Daily reports from the Laboratory Environment Manager system based the selection of nine main reasons for non-conformities, among which "requisition canceled by the management of the GAL due to the expiration of the screening period" was present in 72.8% of the records. Process standardization, in the pre-analytical stage, allows working with security, guaranteeing the quality of the sample to be processed and a reliable result within the established period.


La pandemia del Covid-19 se ha presentado como uno de los desafíos de salud más grandes de este siglo. En diciembre de 2019, China identificó el agente etiológico del nuevo coronavirus llamado SARS-CoV-2. En Brasil, se notificó el primer caso del Covid-19 en febrero de 2020 y, al mes siguiente, la Secretaría de Salud del Estado de Bahía (Sesab) confirmaba el primer caso en Bahía. El Laboratorio Central de Salud Pública Prof. Gonçalo Moniz (Lacen/BA) centralizó el diagnóstico de laboratorio para confirmar los casos sospechosos del coronavirus de los 417 municipios de Bahía, mediante la técnica de RT-PCR. Este estudio tiene como objetivo identificar y analizar las no conformidades de las muestras sospechosas del Covid-19 enviadas al Lacen/BA. Este es un estudio descriptivo cuyos datos se obtuvieron consultando los informes de muestras y pruebas en desacuerdo disponibles en el sistema Laboratory Environment Manager (GAL), generados mensualmente, de abril a octubre/2020. Con el fin de garantizar la calidad de las muestras recibidas, se definieron criterios de aceptación/rechazo de las muestras y se elaboró un formulario para la notificación de no conformidades, asegurando la trazabilidad de las muestras. Por medio de informes diarios del sistema Laboratory Environment Manager, se seleccionaron nueve principales causas de no conformidades, de las cuales la más frecuente fue "requisición cancelada por la gerencia del GAL por vencimiento del período de cribado" con el 72,8% de los registros. La inserción de la estandarización de procesos en la etapa preanalítica permite trabajar con seguridad, garantizando la calidad de la muestra que procesar y, en consecuencia, un resultado confiable dentro del plazo acordado.

ABSTRACT

OBJECTIVE@#To detect fusion gene with pathological significance in a patient with refractory and relapsed acute B cell lymphoblastic leukemia (B-ALL) and to explore its laboratory and clinical characteristics.@*METHODS@#Transcriptome sequencing was used to detect potential fusion transcripts. Other laboratory results and clinical data of the patient were also analyzed.@*RESULTS@#The patient was found to harbor TCF3 exon 17-ZNF384 exon 7 in-frame fusion transcript. The minimal residual disease (MRD) has remained positive after multiple chemotherapy protocols including CD19-, CD22- targeted chimeric antigen receptor T cells immunotherapy. The patient eventually achieved complete remission and sustained MRD negativity after allogeneic hemopoietic stem cell transplantation (allo-HSCT).@*CONCLUSION@#Transcriptome sequencing can effectively detect potential fusion genes with clinical significance in leukemia. TCF3-ZNF384 positive B-ALL has unique laboratory and clinical characteristics, may not well respond to chemotherapy and immunotherapy, and is more likely to relapse. Timely allo-HSCT treatment may help such patients to achieve long-term disease-free survival. TCF3-ZNF384 positive B-ALL is not uncommon in pediatric patients but has not been effectively identified.

ABSTRACT

Fipronil was registered in Uruguay in 1997, and, since then, it has been used for the control of Haematobia irritans irritans and Rhipicephalus microplus. The susceptibility of H. irritants to this drug has not been evaluated. Therefore, the goal of the present study was to evaluate the resistance of H. irritans to fipronil. Additionally, a survey was carried out with the farmers to evaluate the use of fipronil for H. irritans control in the ranches where the flies came from. For the bioassays, 31 field populations of H. irritans were exposed to 10 concentrations of fipronil (3.2-16.0μg.cm2), and their LC50 values were calculated using probit analysis. A bioassay was performed with horn flies from the susceptible colony maintained at the USDA-ARS Knipling-Bushland U.S. Livestock Insects Research Laboratory for comparison and calculation of resistance ratios (RRs). All 31 field populations surveyed in the study were susceptible to fipronil, with resistance ratios ranging from <0.5 to 2.2. Four populations with RRs >1 did not differ significantly from the susceptible strain. A single population showed an RR >2.2. Overall, the survey shows that fipronil was mostly used for R. microplus control, and in only three ranches, which were free of R. microplus, was fipronil used for horn fly control. Seventeen farmers did not use fipronil at all in the last three years. It is concluded that, in Uruguay, field populations of horn flies remain susceptible to fipronil.(AU)


O fipronil foi registrado no Uruguai em 1997 e, desde então, tem sido utilizado no controle de Haematobia irritans irritans e Rhipicephalus microplus. O objetivo do presente estudo foi avaliar a susceptibilidade de populações de campo de H. irritans ao fipronil. Além disso, foi realizada uma pesquisa para avaliar a utilização de fipronil e as práticas de controle de H. irritans nas fazendas de onde provinham as moscas. Para os bioensaios, 31 populações de campo de H. irritans foram expostas a 10 concentrações de fipronil (3,2-16,0μg.cm2), e seus valores de CL50 foram calculados usando análise probit. Um bioensaio foi realizado com H. irritans da colônia suscetível mantida no USDA-ARS Knipling-Bushland U.S. Livestock Insects Research Laboratory para comparação e cálculo das razões de resistência (RRs). Todas as 31 populações de campo pesquisadas no estudo eram suscetíveis ao fipronil, com taxas de resistência variando de <0,5 à 2,2. Quatro populações com Rrs >1 não diferiram significativamente da cepa suscetível. Uma única população apresentou RR >2,2. No geral, o fipronil tinha sido usado principalmente para o controle de R. microplus, e em apenas três fazendas, que estavam livres de R. microplus, o fipronil era utilizado para o controle da H. irritans. Em 17 fazendas não tinha sido utilizado fipronil nos últimos três anos. Conclui-se que no Uruguai as populações de H. irritans no campo permanecem suscetíveis ao fipronil.(AU)

ABSTRACT

Nucleic acid detection technique has good sensitivity and specificity and is widely used in in vitro diagnosis, animal and plant commodity quarantine, forensic identification, and other fields. However, it is susceptible to carryover contamination during the operation and leads to false-positive results, which seriously affects the detection accuracy. Therefore, finding an effective solution to prevent and eliminate nucleic acid carryover contamination has become particularly urgent. This study compared several different methods for removing nucleic acid contamination and confirmed that sodium hypochlorite solution and PCRguard reagent could effectively eliminate nucleic acid carryover in the liquid and on surfaces of different materials. Besides, the combination of sodium hypochlorite solution and PCRguard can solve the nucleic acid aerosol contamination. This study proposes solutions for the routine prevention of carryover contamination and removal of aerosol that has occurred in molecular diagnostic laboratories.

ABSTRACT

In recent years, adaptive laboratory evolution (ALE) has emerged as a powerful tool for basic research in microbiology (e.g., molecular mechanisms of microbial evolution) and efforts on evolutionary engineering of microbial strains (e.g., accelerated evolution of industrial strains by bringing beneficial mutations). The ongoing rapid development of next-generation sequencing platforms has provided novel insights into growth kinetics and metabolism of microbes, and thus led to great advances of this technique. In this review, we summarize recent advances in the applications of long-term and short-term ALE techniques mainly for microbial strain engineering, and different modes of ALE are also introduced. Furthermore, we discuss the current limitations of ALE and potential solutions. We believe that the information reviewed here will make a significant contribution to further advancement of ALE.

ABSTRACT

BACKGROUND@#Fecal immunochemical tests (FITs) are the most widely used non-invasive tests in colorectal cancer (CRC) screening. However, evidence about the direct comparison of the test performance of the self-administered qualitative a laboratory-based quantitative FITs in a CRC screening setting is sparse.@*METHODS@#Based on a CRC screening trial (TARGET-C), we included 3144 pre-colonoscopy fecal samples, including 24 CRCs, 230 advanced adenomas, 622 non-advanced adenomas, and 2268 participants without significant findings at colonoscopy. Three self-administered qualitative FITs (Pupu tube) with positivity thresholds of 8.0, 14.4, or 20.8 μg hemoglobin (Hb)/g preset by the manufacturer and one laboratory-based quantitative FIT (OC-Sensor) with a positivity threshold of 20 μg Hb/g recommended by the manufacturer were tested by trained staff in the central laboratory. The diagnostic performance of the FITs for detecting colorectal neoplasms was compared in the different scenarios using the preset and adjusted thresholds (for the quantitative FIT).@*RESULTS@#At the thresholds preset by the manufacturers, apart from the qualitative FIT-3, significantly higher sensitivities for detecting advanced adenoma were observed for the qualitative FIT-1 (33.9% [95% CI: 28.7-39.4%]) and qualitative FIT-2 (22.2% [95% CI: 17.7-27.2%]) compared to the quantitative FIT (11.7% [95% CI: 8.4-15.8%]), while at a cost of significantly lower specificities. However, such difference was not observed for detecting CRC. For scenarios of adjusting the positivity thresholds of the quantitative FIT to yield comparable specificity or comparable positivity rate to the three qualitative FITs accordingly, there were no significant differences in terms of sensitivity, specificity, positive/negative predictive values and positive/negative likelihood ratios for detecting CRC or advanced adenoma between the two types of FITs, which was further evidenced in ROC analysis.@*CONCLUSIONS@#Although the self-administered qualitative and the laboratory-based quantitative FITs had varied test performance at the positivity thresholds preset by the manufacturer, such heterogeneity could be overcome by adjusting thresholds to yield comparable specificities or positivity rates. Future CRC screening programs should select appropriate types of FITs and define the thresholds based on the targeted specificities and manageable positivity rates.

ABSTRACT

Meigs' syndrome (MS), a rare complication of benign ovarian tumors, is easily misdiagnosed as ovarian cancer (OC). We retrospectively reviewed the clinical laboratory data of patients diagnosed with MS from 2009 to 2018. Serum carbohydrate antigen 125 and HE4 levels were higher in the MS group than in the ovarian thecoma-fibroma (OTF) and healthy control groups (all P < 0.05). However, the serum HE4 levels were lower in the MS group than in the OC group (P < 0.001). A routine blood test showed that the absolute counts and percentages of lymphocytes were significantly lower in the MS group than in the OTF and control groups (all P < 0.05). However, these variables were higher in the MS group than in the OC group (both P < 0.05). The neutrophil-to-lymphocyte ratio (NLR) was also significantly lower, whereas the lymphocyte-to-monocyte ratio was higher in the MS group than in the OC group (both P < 0.05). The NLR, platelet-to-lymphocyte ratio, and systemic immune index were significantly higher in the MS group than in the OTF and control groups (all P < 0.05). The hypoxia-inducible factor-1 mRNA levels were also significantly higher, whereas the glucose transporter 1, lactate dehydrogenase, and enolase 1 mRNA levels were lower in peripheral CD4
