Effect of Lubricant Use on Cervicovaginal Cytology - What's the Evidence? / Efeito do uso de lubrificante na citologia cervicovaginal - Qual a evidência?

Abstract Objective To determine if the use of lubricating gel on the speculum during the cervicovaginal cytology examination interferes with the results obtained, as well as whether it reduces reported discomfort in patients. Data sources A systematic review was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations, with a search in the Pubmed/Medline, Scielo, Cochrane Library, Embase databases of articles published between January 2011 and May 2022. The keywords used were cytology, speculum, lubricant, result, and pain. Selection of studies The initial search resulted in 306 articles, of which were excluded three because they were duplicates, 257 after reading the title and abstract and 41 after reading the full text. Thus, five articles were selected for the study: four randomized clinical trials and one metanalysis. Data collection The selection of articles was performed by two investigators. The 5 selected articles were read in full and submitted to a comparative analysis. Data synthesis Screening through cervicovaginal cytology allows for early diagnosis and reduction of associated mortality, but the procedure can be associated with pain. A small amount of aqueous lubricating gel in the speculum can be used to reduce the discomfort associated with performing cervicovaginal cytology. Conclusion The use of lubricating gel in the speculum does not seem to be associated with a change in the cytology result and reduces the discomfort associated with its insertion into the vagina.

Utilizaram-se as palavras-chave citologia, espéculo, lubrificante, resultado e dor. Seleção dos estudos A pesquisa inicial resultou em 306 artigos, dos quais foram excluídos três por se encontrarem duplicados, 257 após a leitura do título e do resumo e 41 após a leitura integral. Assim, foram selecionados cinco artigos para o estudo: quatro ensaios clínicos aleatorizados e uma metanálise. Coleta de dados A seleção dos artigos foi realizada por dois investigadores. Os cinco artigos selecionados foram lidos na íntegra e submetidos a uma análise comparativa. Síntese dos dados O rastreio através da citologia cervicovaginal permite um diagnóstico precoce e redução da mortalidade associada, mas a sua realização pode estar associada a dor. Uma pequena quantidade de gel lubrificante aquoso pode ser utilizada no espéculo para diminuir o desconforto associado à realização da citologia cervicovaginal. Conclusão A utilização de gel lubrificante não está associada a alteração do resultado da citologia e diminui o desconforto associado à sua introdução na vagina.

Treatment of anterior shoulder instability by latarjet coracoid bone block: preliminary functional results in a subsaharan hospital

Background: The Latarjet technique aims to stabilize the shoulder by reconstructing the glenoid rim using a bone fragment taken from the coracoid bone and generally fixed to the anteroinferior part of the glenoid. The aim of this study was to assess the functional outcome of this type of treatment. Methods: This retrospective study was conducted in several health institutions in Ivory Coast from January 2008 to December 2013. Folders of 15 patients whose shoulders were treated by the Latarjet coracoid bone block procedure for anterior shoulder instability and were followed-up for a minimum of 10 years were retrieved and data collected. Functional outcomes were assessed by the Rowe score. The data were evaluated and analysed using Epi Info and Excel statistical software. Results: The functional assessment according to the Rowe score revealed three excellent results, nine good results, two average results and one poor result. One case of recurrence was observed in the postoperative period and required a revision. Conclusion: This study suggests that the Latarjet preglenoid bone block procedure is an effective surgical procedure for treating anterior shoulder instability. It allows for a significant improvement in functional outcomes as well as a satisfactory return to sporting activity.

Analysis of the types and causes of invalid results in nucleic acid test for blood screening / 中国输血杂志

【Objective】 To analyze the reasons for the invalidity of blood nucleic acid test results, and to explore the countermeasures to reduce the invalidity of the test. 【Methods】 From 2019 to 2021, the number of tests performed in our laboratory for Cobas s201 blood nucleic acid screening system and the number of batches and tests with invalid results were counted, and the types and reasons of invalid results were analyzed. 【Results】 From 2019 to 2021, the Cobas s201 nucleic acid detection system detected a total of 5, 420 batches and 127, 950 pools, and the invalid rate of batches and pools were 1.83% and 1.97%, respectively. The types of invalid results can be summarized as improper operation, sample quality problems, invalid quality control (IQC), equipment failure and others. Among them, IQC and equipment failure were the main reasons for invalid results, accounting for 44.51% and 39.96%, respectively. IQC was mainly related to cross-contamination of samples and insufficient mixing of quality control products. Equipment failures mostly occurred in the robotic arm gripper of the nucleic acid extraction instrument and the TC module of the amplification instrument. 【Conclusion】 The laboratory should conduct quality monitoring for invalid results, and take targeted improvement measures, especially to reduce invalid results caused by invalid quality control and instrument failure.

The author suggestted that hospitals should highlight the value orientation of patents, strengthen-industry-academia-research cooperation, establish a professional management team and standardized management system for intellectual property, cultivate high-value patents, conduct pre patent application evaluation and screening, and improve patent conversion and technological innovation capabilities.

A atuação do empresário no executivo municipal apresenta melhores resultados? / ¿El emprendedor en el Poder Ejecutivo Municipal tiene mejores resultados? / Is a business owner a better mayor?

Resumo O objetivo deste artigo é levantar as características demográficas dos prefeitos eleitos, enfatizando os candidatos que se declaram empresários, e analisar se esse perfil tem melhores resultados quanto ao desempenho, medidos com base na situação fiscal e no Índice de Educação Básica (IDEB) do município. Para tanto, o trabalho foi dividido em duas partes. Na primeira, por meio de regressão logística, buscou-se encontrar o perfil do candidato eleito, centrando-se no fato de ele ser empresário. Na segunda seção do artigo, com o emprego da metodologia de regressão multinível, foi analisado se tal perfil escolhido pelos eleitores era responsável por um desempenho superior. Com relação aos resultados, apesar de os empresários constituírem a maioria entre os candidatos, essa característica não foi significativa para o sucesso eleitoral. Na segunda parte da pesquisa, de modo geral os resultados não encontraram correlação entre o perfil dos eleitos e o desempenho da gestão municipal. Somente a idade do prefeito foi significativa na questão fiscal dos municípios. Dessa forma, os empresários não apresentam resultados diferentes da média, o que permite pressupor que esse grupo não tem melhores habilidades e julgamentos.

Resumen El objetivo de este artículo es sondear las características demográficas de los alcaldes electos elegidos, con énfasis en los candidatos que se declaran emprendedores, y analizar si este perfil tiene mejores resultados de desempeño, medido por la situación fiscal del municipio y el puntaje del IDEB (Índice de Desarrollo de la Educación Básica). Para ello, el trabajo se dividió en dos partes. En la primera, mediante regresión logística, se buscó encontrar el perfil del candidato elegido. En la segunda parte del artículo se analizó si el perfil elegido por los votantes era responsable de un desempeño superior. La metodología utilizada fue la de regresión multinivel. En cuanto a los resultados, a pesar de que los empresarios fueron mayoría entre los candidatos, esta característica no fue significativa para explicar el éxito electoral. En general, en la segunda parte de la investigación, los resultados no demostraron correlación entre el perfil de los elegidos y el desempeño de la gestión municipal. Solo la edad del alcalde fue significativa para explicar el tema fiscal de los municipios. De esta forma, los emprendedores no presentan resultados diferentes a la media, lo que nos permite concluir que este grupo no tiene mejores habilidades y juicios. Entre las limitaciones de este trabajo, está la cuestión de que la variable "emprendedor" haya sido declarada libremente por los candidatos.

Abstract This study analyzes the demographic characteristics of elected mayors in Brazil, emphasizing those who are business owners. The research observes whether mayors with a background as business owners obtain better performance in office, which is evaluated through the municipality's fiscal situation and the IDEB (basic education development index) score. The research was conducted in two parts. The first part used logistic regression and sought to identify the profile of elected mayors. The second part analyzed whether mayors who were business owners obtained a superior performance using the multilevel regression model. The study observed that the majority of mayors had a background as business owners, but this characteristic was not significant to explain electoral success. The results of the second part did not find a correlation between mayors who are business owners and their performance. The only demographic characteristic relevant to explain differences in municipalities' fiscal results was the mayor's age. Therefore, mayors who were business owners did not present results different from those who have other backgrounds, which allows us to assume that this group does not have better skills and judgments. One of the limitations of this study is that the characteristic of being a business owner was obtained by self-declaration.

DIFFERENT MODALITIES IN THE MANAGEMENT OF OCULAR SURFACE SQUAMOUS NEOPLASIA

Purpose: To study the different modalities in the management of Ocular Surface SquamousNeoplasia(OSSN).Method: A prospective study of 30 cases of OSSN was undertaken. Based on patient factors andtumour size and characteristics , 20 patients underwent surgical excision with cryotherapy and 10patients were managed conservatively with topical interferon therapy. Patients were followed up for aperiod of nine months.Results: OSSN is more common in males (80%) with mean age of 55 years (range 30-76 years).Histopathology report of excision biopsy showed 6 benign dysplasia, 8 carcinoma in situ and 6invasive squamous carcinoma. Postoperative topical interferon reduced the risk of recurrence.Of the patients who underwent interferon therapy, complete resolution was seen in 6 cases.Conclusion : Management of OSSN requires adequate excision and regular follow up to monitor anyrecurrence. Although surgical excision is still the gold standard for OSSN treatment, topicalinterferon has revolutionised the management of OSSN. Pre and Post operative adjunctive therapyshould be considered to prevent recurrence.

A comparison of clinical characteristics between acute fatty liver of pregnancy and hemolysis, elevated liver enzymes and low platelets syndrome / 中华危重病急救医学

Objective:To compare and analyze the clinical characteristics between acute fatty liver of pregnancy (AFLP) and the hemolysis, elevated liver enzymes and low platelets (HELLP) syndrome.Methods:This is a retrospective cohort study. The clinical data of 13 cases with AFLP and 34 cases with HELLP syndrome were collected from three tertiary referral centers in Yunnan (the First Affiliated Hospital of Kunming Medical University, the Second Affiliated Hospital of Kunming Medical University, and Yan'an Hospital of Kunming City) from January 2016 to December 2021. The patients were diagnosed to AFLP and HELLP syndrome according to the Swansea criteria and the Tennessee classification system. The general characteristics, clinical features, laboratory results within 24 hours after admission, complications, maternal and neonatal outcomes were compared to analysis the differences between the two groups.Results:① Maternal characteristics: compared with HELLP syndrome group, AFLP group had lower body mass index (BMI) and blood pressure at admission (both P < 0.01). ②Clinical features: the most common symptoms in AFLP patients were skin jaundice, abdominal pain, nausea and vomiting, edema. The main manifestations of patients with HELLP syndrome were albuminuria, hypertension, edema, headache. Some patients had multiple symptoms concurrently. ③ Laboratory results: compared with HELLP syndrome group, the levels of platelet count (PLT), total bilirubin (TBil), direct bilirubin (DBil), γ-glutamyl transferase (γ-GGT), alkaline phosphatase (ALP), total bile acid (TBA), serum creatinine (SCr) and international standardized ratio (INR) in AFLP group were significantly increased within 24 hours after admission [PLT (×10 9/L): 107.69±51.13 vs.76.71±43.25, TBil (μmol/L): 121.60 (83.20, 170.00) vs.15.25 (7.22, 29.05), DBil (μmol/L): 86.50 (58.60, 104.00) vs. 4.30 (2.22, 10.10), γ-GGT (U/L): 87.00 (37.00, 127.00) vs. 41.00 (19.00, 64.42), ALP (U/L): 199.10 (109.00, 349.20) vs. 125.50 (90.50, 155.25), TBA (μmol/L): 51.50 (16.20, 117.40) vs. 4.15 (2.02, 6.95), SCr (μmol/L): 155.80 (129.00, 237.00) vs. 79.00 (65.43, 113.70), INR: 1.28 (1.17, 1.63) vs. 0.94 (0.88, 1.08), all P < 0.05], prothrombin time (PT) was significantly prolonged [seconds: 16.10 (14.50, 19.20) vs. 12.40 (11.43, 13.40), P < 0.05]. The level of blood glucose (GLU), fibrinogen (FIB) and the activity of antithrombin Ⅲ (ATⅢ) decreased significantly [GLU (mmol/L): 5.18±1.33 vs. 6.33±1.19, FIB (g/L): 1.96±1.46 vs. 3.81±1.58, ATⅢ (%): 40.61±25.84 vs. 66.39±24.11, all P < 0.05]; ④ Complications: compared with HELLP syndrome group, the incidence of patients with hypoglycemia [30.77% (4/13) vs. 0% (0/34)], acute liver failure [53.85% (7/13) vs. 5.88% (2/34)], acute renal insufficiency [69.23% (9/13) vs. 8.82% (3/34)], coagulopathy [76.92% (10/13) vs. 38.24% (13/34)], disseminated intravascular coagulation (DIC) [53.85% (7/13) vs. 5.88% (2/34)], and multiple organ dysfunction syndrome (MODS) [53.85% (7/13) vs. 5.88% (2/34)] were significantly higher in AFLP group (all P < 0.05). ⑤ Maternal and neonatal outcome: all patients delivered after admission. The total length of hospital and intensive care unit stay were significantly longer in the AFLP group than in the HELLP syndrome group [days: 17.00 (11.00, 25.00) vs. 9.00 (7.00, 12.00), 12.00 (4.00, 22.00) vs. 3.91 (0, 7.00), both P < 0.01]. Two AFLP patients died, including one due to intracranial venous thrombosis and one due to multiple organ failure and cardiopulmonary arrest. There were no deaths in the HELLP syndrome group. Conclusions:There are significant differences in maternal characteristics, laboratory results and complications between AFLP and HELLP syndrome. TBil, γ-GGT, SCr, FIB, INR and ATⅢ activity may help to distinguish the two diseases.

Explore on the cultivation of research potential of eight-year program students through the results of blind evaluation of dissertations / 中华医学教育探索杂志

Objective:To understand the results of blind evaluation of dissertation of three-year doctors and eight-year medical doctors, and to explore the improvement measures of eight-year program education.Methods:The data analysis method was manipulated. A total of 47 eight-year doctoral and 88 three-year doctoral dissertations submitted by the first clinical college of Huazhong University of Science and Technology in 2020 were selected as the research material. SPSS 17.0 was used to perform Chi-square test to compare the itemized evaluation opinions of the dissertation, Spearman test was used to analyze the correlation between the defense opinions, itemized evaluation opinions and the overall evaluation.Results:The gap between eight-year and three-year doctoral dissertation is mainly manifested in innovation and research value ( χ2=9.10, P=0.003), topic and review ( χ2=5.70, P=0.017), while there is no significant difference in the overall assessment and oral defense suggestion. The main influencing factor of dissertation defense suggestion for both doctors was the dissertation standardization (eight-year: r s=0.53, P<0.001; three-year: r s=0.45, P<0.001). The evaluation results of eight-year doctor dissertation were closely related to basic knowledge and scientific research ability ( r s=0.74, P<0.001). Conclusion:There is no significant difference between eight-year doctors and full-time doctors in research attitude. But there was a certain gap in scientific research and innovation ability among them. It is suggested to clarify the teaching objectives, formulate and refine the evaluation system of dissertations, and strengthen the cultivation of scientific research interest and academic belief of eight-year study program.

Trauma informed occupational therapy school practice with adolescents with social emotional and behavioural difficulties: findings of standardised measures / Trauma informando práticas escolares em terapia ocupacional com adolescentes em dificuldades socioemocionais e comportamentais: achados a partir de medidas padronizadas

Abstract Introduction Although non-standardized qualitative and quantitative reports from 39 Irish students aged 12 to 14 years, with complex social and emotional needs and their 13 teachers had established benefits of 'Movement Matters', an occupational therapy designed participatory curriculum for learning self-regulation in mainstream schools (National Behaviour Support Service, 2015a), standardized measures were required for quality assurance by the Irish Government funded service. Objective The relevance of findings of standardized attitude measurements on the impacts of an occupation focused intervention with a discrete school population in areas of social disadvantage are discussed. Method Findings of the 'Pupil Attitude to Self and School' (PASS) (Granada Learning, 2021) and 'Strengths and Difficulties Questionnaire' (SDQ) (Youth in Mind, 2021), both well-established standardized measures of attitude and behaviours completed (pre and post intervention) by teachers, parents and students are presented. Results No statistically significant differences were found between the standardized pre and post intervention measures. However, findings indicate a disparity between how these students in complex environments experience school in comparison to large UK study populations. Conclusion This paper discusses the use of these standardized measures for capturing impacts of an occupation focused intervention in a school environment. It calls for an increased appreciation on outcomes measurement related to the intervention's aim of providing experiences of meaningful participation and well-being. Further collaborative research on outcome measurement of participation of students in complex mainstream school environments is required.

Resumo Introdução Embora relatórios qualitativos e quantitativos não padronizados de 39 estudantes irlandeses, de 12 a 14 anos, com necessidades sociais e emocionais complexas e seus 13 professores tenham estabelecido benefícios de 'Movement Matters', uma terapeuta ocupacional projetou um currículo participativo para aprender autorregulação no ensino regular (National Behaviour Support Service, 2015a), tendo sido necessárias medidas padronizadas para garantia de qualidade do serviço financiado pelo governo Irlandês. Objetivo Discutir a relevância dos resultados das medidas de atitudes padronizadas sobre os impactos de uma intervenção focada na ocupação com uma população escolar em áreas de desvantagem social. Método São apresentados dados do 'Pupil Attitude to Self and School' (PASS) (Granada Learning, 2021) e 'Strengths and Difficulties Questionnaire' (SDQ) (Youth in Mind, 2021), ambas medidas padronizadas bem estabelecidas de atitude e comportamentos (pré e pós-intervenção) por professores, pais e alunos. Resultados Não foram encontradas diferenças estatisticamente significativas entre as medidas padronizadas pré e pós-intervenção. No entanto, os resultados indicam uma disparidade sobre como esses alunos vivenciam a escola em ambientes complexos, em comparação com estudos de grandes populações no Reino Unido. Conclusão Este artigo discute o uso dessas medidas padronizadas para compreender os impactos de uma intervenção focada na ocupação em um ambiente escolar. Observa-se a necessidade de uma maior apreciação da medição de resultados relacionados ao objetivo da intervenção ao fornecer experiências de participação e bem-estar significativos. São necessárias mais investigações colaborativas sobre a medição dos resultados da participação dos alunos em ambientes complexos de escolas regulares.

Results: According to injury location, the lowest visual results were obtained in patients with zone I lesions, whereas the best results corresponded to zone III lesions. A better visual result evolution was achieved in patients with lesions smaller than or equal to a papillary diameter. A statistical difference was found between the various degrees of inflammation severity, with a tendency to an increase in best corrected visual acuity with the passing of time after treatment. Conclusions: Visual improvement is achieved during the evolution of immunocompetent patients with active ocular toxoplasmosis(AU)

Introducción de resultados científicos: bases teórico-metodológicas para su mejora en la educación médica / Introduction of scientific results: theoretic-methodological bases for its improvement in medical education

RESUMEN En Cuba, la transformación de la realidad por medio de la introducción de resultados científicos -en aras del desarrollo sostenible-, es una alta prioridad por parte de las primeras instancias de dirección desde 1959. La introducción de resultados investigativos ha sido abordada por prestigiosos autores desde diferentes aristas y contextos, pero existen escasas referencias relacionadas con el tema en el ámbito de las ciencias de la educación médica. En consecuencia, este artículo presenta un análisis sobre las tendencias del proceso de introducción de resultados científicos en el ámbito académico, para luego delinear cuáles pudieran ser las bases teórico-metodológicas para la mejora del proceso en el ámbito de la educación médica (AU).

ABSTRACT In Cuba, the transformation of reality through the introduction of scientific results -for the sake of the sustainable development- is a high priority for the first instances of direction since 1959. The introduction of research results has been approached by prestigious authors from different edges and in different contexts, but there are few references related to the theme in the field of the medical education sciences. Consequently, this article presents an analysis on the tendencies of the process of introducing scientific results in the academic sphere, and then outlines the possible theoretic-methodological bases for improving the process in the field of medical education (AU).

Resultados tempranos en pacientes con cáncer gástrico sometidos a gastrectomía laparoscópica con intención curativa / Early results in gastric cancer patients undergoing laparoscopic gastrectomy with curative intent

Introducción. El manejo de pacientes con cáncer gástrico está determinado por el estadio preoperatorio y requiere de una estrategia multidisciplinaria. La cirugía radical, especialmente en pacientes con estadios tempranos, es potencialmente curativa. El abordaje por vía laparoscópica ofrece ventajas sobre la vía abierta, sin embargo, en nuestro medio no hay información en cuanto a resultados oncológicos y posoperatorios tempranos. Métodos. Estudio retrospectivo, descriptivo, de tipo transversal, en pacientes con cáncer gástrico llevados a gastrectomía laparoscópica con intención curativa, entre el 2014 y el 2019, en tres instituciones de la ciudad de Medellín. Se analizaron los datos demográficos, los resultados posoperatorios y oncológicos a corto plazo. Resultados. Se incluyeron 75 pacientes sometidos a gastrectomía laparoscópica. La mediana de edad fue de 64 años y el estadio más frecuente fue el III. La gastrectomía fue subtotal en 50 pacientes (66,7 %) y total en 25 pacientes (33,3 %). Se hizo disección linfática D2 en 73 pacientes (97,3 %) con una mediana en el recuento ganglionar de 27. La tasa de resección R0 fue de 97,3 %. La mediana de estancia hospitalaria fue de seis días. La tasa de complicaciones mayores fue del 20 % y la mortalidad a 90 días fue del 4 %. Discusión. La calidad oncológica de la gastrectomía laparoscópica fue adecuada y cumple con las recomendaciones de las guías internacionales. Si bien la morbilidad sigue siendo alta, tiene una tasa de sobrevida del 96 % a 90 días.

Introduction. The management of patients with gastric cancer is determined by the preoperative stage and requires a multidisciplinary strategy. Radical surgery, especially in patients with early stages, is potentially curative. The laparoscopic approach offers advantages over the open approach, however, in our setting there is no information regarding oncological and early postoperative results.Methods. Retrospective, descriptive, cross-sectional study in patients with gastric cancer who underwent laparoscopic gastrectomy with curative intent, between 2014 and 2019, in three institutions in the city of Medellín. Demographic data, postoperative and short-term oncological results were analyzed.Results. Seventy-five patients undergoing laparoscopic gastrectomy were included. The median age was 64 years and the most frequent stage was III. Gastrectomy was subtotal in 50 patients (66.7%) and total in 25 patients (33.3%). D2 lymphatic dissection was performed in 73 patients (97.3%) with a median lymph node count of 27. The R0 resection rate was 97.3%. The median hospital stay was six days. The major complication rate was 20% and the 90-day mortality was 4%.Discussion. The oncological quality of the laparoscopic gastrectomy was adequate and complies with the recommendations of international guidelines. Although morbidity remains high, it has a 96% survival rate at 90 days

Investigation and analysis of an epidemic situation of human brucellosis in Fushan District, Yantai City, Shandong Province / 中华地方病学杂志

Objective:To investigate and analyze a human brucellosis (hereinafter referred to as brucellosis) in Fushan District, Yantai City of Shandong Province, and to provide scientific basis for study the main risk factors and doing a good job in brucellosis prevention and control.Methods:Collect the epidemic data of one human brucellosis in Fushan District, Yantai City in 2017. The information comes from the infectious disease report information management system, the epidemiological case questionnaire of brucellosis in Shandong Province, and the medical records of medical institutions. The epidemic situation, cases and epidemiological investigation results were analyzed retrospectively.Results:Serological tests were carried out among 48 close contacts of the reported case and workers in the same village. Among the 3 positive cases, 2 cases had symptoms and positive bacterial culture results, which were diagnosed as confirmed cases. One patient was asymptomatic and negative bacterial culture, and was diagnosed as recessive infection. All of the three confirmed cases and one recessive infection involved in the epidemic had a history of close contact with infected animals, and without protective measures. The serological examination of 70 key people in the district was carried out and the results were all negative. A total of 166 sheep blood samples were collected, including 21 positive samples.Conclusions:The infectious source of this outbreak is the non-quarantine infected sheep. The main exposure factor is personal unprotected exposure to infected sheep. The key of prevention and control is to strengthen the monitoring and quarantine management of brucellosis among livestock, to improve the personal protection consciousness and ability of key population, and to improve the diagnosis ability of medical institutions in low epidemic areas.

Epidemiological investigation and follow-up study of indeterminate HIV antibody test results in Jiading, Shanghai / 上海预防医学

Objective To investigate the rate and the population distribution of subjects with indeterminate result of HIV antibody test and to understand the relationships between the western blot(WB)banding patterns and HIV infection through follow-up reexamination. Methods Samples with indeterminate results of HIV antibody test were collected by Jiading Center for Disease Control and Prevention from 2013 to 2017. They were used for analysis of the source, the distribution of Western blotting band pattern and the follow-up results. Results Among 698 samples required to be re-tested for confirmation of HIV infection, 151(21.63%)showed indeterminate WB test results. There were 18 types of WB band in 151 HIV antibody-indeterminate samples. The most common band types, accounting for 79.47%, were p24, gp160, and gp160p24. One hundred(among 151)subjects were followed up and the success follow-up rate was 50.00%. Among them, 28(56.00%)samples were still with indeterminate results of HIV antibody, 11(22.00% turned to be negative and 11(22.00%)turned to positive. The follow-up confirmatory tests showed that 67.86% of the samples with p24 band were still with indeterminate results and 40.00% of the samples with gp160 band became HIV antibody-negative. The samples with one of the three band patterns of gp160gp120p24, gp160p24p17 and gp160gp120p66p51 all became HIV antibody-positive. Conclusion The detection rate of indeterminate HIV antibody results varies in different populations. Positive conversion rates with different WB band patterns are different. Follow-up of the populations with specific WB band patterns should be strengthened to detect HIV infection cases as early as possible.

Métodos diagnósticos para la infección por SARS-CoV-2 / Diagnostic methods for SARS-CoV-2 infection

En diciembre de 2019 se identificó el virus SARS-CoV-2, cuya rápida propagación global puso en estado de emergencia al mundo entero, llevando al ser humano a una situación sin antecedente cercano. El objetivo de esta revisión es describir los métodos diagnósticos utilizados actualmente para identificar la infección por SARS-CoV-2. Las manifestaciones clínicas y el espectro imagenológico de la enfermedad son muy inespecíficos y no permiten realizar un diagnóstico certero. Por esta razón, es esencial una apropiada toma de muestra respiratoria en el momento y sitio anatómico adecuado para un diagnóstico preciso de COVID-19. La técnica de muestreo más utilizada es el hisopado nasofaríngeo y la prueba diagnóstica más fiable se basa en la retrotranscripción seguida por reacción en cadena de la polimerasa en tiempo real (RT-PCR). No obstante, existen otras técnicas moleculares, como también tests serológicos para detectar anticuerpos o fragmentos antigénicos del SARS-CoV-2. Más allá de la precisión diagnóstica, es importante tener en cuenta la probabilidad basal (pretest) para interpretar correctamente el resultado obtenido y aislar aquellos posibles falsos negativos. Con el objetivo de evitar la saturación del sistema de salud es imprescindible contar con información y métodos diagnósticos precisos para detectar tempranamente los focos de infección y reducir la transmisión comunitaria, utilizando eficazmente los diferentes recursos diagnósticos. (AU)

In December 2019, the SARS-CoV-2 virus was identified for the first time, whose rapid global spread put the entire world in a state of emergency, leading humans to an unprecedented situation with no immediate history. The main purpose of this review is to describe the diagnostic methods currently used to identify SARS-CoV-2 infection. The clinical manifestations and the imaging spectrum of the disease are nonspecific and do not allow an accurate diagnosis to be made. For this reason, an appropriate respiratory sampling at the right time and anatomical site is essential for an accurate diagnosis of COVID-19. The most widely used sampling technique is nasopharyngeal swab, and the most reliable diagnostic test is by reverse transcription followed by real-time polymerase chain reaction (RT-PCR). However, there are other molecular techniques, as well as serological tests to detect antibodies or antigenic fragments of SARS-CoV-2. Beyond the diagnostic precision, it is important to take into account the baseline probability (pre-test) to correctly interpret the result obtained and isolate those possible false negatives. In order to avoid saturation of the health system, it is essential to have accurate information and diagnostic methods to detect outbreaks of infection in early stages and to reduce communitary transmission, making effective use of the various diagnostic resources. Coronavirus infections/diagnosis, viral/diagnosis, pandemics, clinical laboratory techniques, real-time polymerase chain reaction, antigens, viral/analysis. (AU)
