ABSTRACT Background: Relatively low SARS-CoV-2 reinfection rates have been reported in vaccinated individuals, but updates considering the Omicron variant are lacking. Objective: The objective of the study was to provide a current estimate of the SARS-CoV-2 reinfection rate in a highly immunized population. Methods: A prospective cohort of Mexican hospital workers was followed (March 2020-February 2022). Reinfection was defined as the occurrence of two or more episodes of COVID-19 separated by a period of ≥ 90 days without symptoms. The reinfection rate was calculated as the number of reinfection episodes per 100,000 persons per day. Results: A total of 3732 medical consultations were provided to 2700 workers, of whom 1388 (51.4%) were confirmed COVID-19 cases. A total of 73 reinfection cases were identified, of whom 71 (97.3%) had completed their primary vaccination series and 22 (30.1%) had had a booster dose before the second episode. The overall reinfection rate was 23.1 per 100,000 persons per day (as compared to a rate of 1.9 per 100,000 persons per day before the Omicron wave). Conclusions: The SARS-CoV-2 reinfection rate rose significantly during the Omicron wave despite a high primary vaccination coverage rate. Almost one-third of reinfected workers had a vaccine booster ≥ 14 days before the last COVID-19 episode.

Abstract Latex allergy is a major problem worldwide due to both the severity of the symptomatology it produces and the risk groups that are exposed to it. Complete avoidance is difficult, if not impossible, due to its ubiquity. Natural rubber latex (NRL) is a natural polymer that is released by the Hevea brasiliensis (Hev b) tree, which functions as a protective sealant. It is currently used for the manufacture of health-care products such as tube caps, pistons, masks, and cannulas. The purpose of this review is to highlight the epidemiological, clinical, and diagnostic aspects of NRL allergy, and to conduct a review of the literature on its management through a bibliographic search of articles in databases such as PubMed, Cochrane, UpToDate, and Google Scholar, up to September 2021. About 121 articles were reviewed, of which 76 were used as a reference. We concluded that latex allergy is an entity for which its treatment, even nowadays, is avoidance, despite having a worldwide prevalence of 4.3 % and representing a surgical complication in about 20 % of surgeries with an anaphylactic reaction and a mortality rate that can reach 9 %. The only treatment that could modify the evolution of this disease is immunotherapy, but there are no standardized extracts yet and it has not been possible to determine the safest and most effective way to apply it.

Resumen La alergia al látex es un problema importante en el mundo debido a la gravedad de la sintomatología que produce y a los grupos de riesgo expuestos. La evitación completa es difícil, casi imposible, dada su ubicuidad. El látex de caucho natural (LCN) es un polímero secretado por el árbol Hevea brasiliensis (Hev b), que funciona como sellador protector. Actualmente se usa para fabricar productos para el cuidado de la salud como tapones para tubos, pistones, mascarillas y cánulas. El objetivo de esta revisión es resaltar los aspectos epidemiológicos, clínicos y diagnósticos de la alergia al LCN, y realizar una revisión de la literatura sobre su manejo, mediante una búsqueda bibliográfica de artículos en bases de datos como PubMed, Cochrane, UpToDate y Google Académico, hasta septiembre del 2021. Se revisaron aproximadamente 121 artículos, de los cuales se utilizaron 76 como referencia. Concluimos que la alergia al látex es una entidad cuyo tratamiento aún hoy en día es la evitación, a pesar de tener una prevalencia mundial de 4.3 % y representar una complicación quirúrgica de cerca de 20 % de las cirugías con una reacción anafiláctica y una mortalidad que puede llegar a 9 %. El único tratamiento que podría modificar la evolución de esta enfermedad es la inmunoterapia, pero aún no se cuenta con extractos estandarizados y no se ha podido determinar la vía más segura y efectiva.

Abstract. Research objective was to assess phytosanitary response and epidemiological behavior in 12 Phaseolus vulgaris genotypes and develop etiological-epidemiological methodologies applicable to plant breeding studies. In 2020 spring-summer season, assessments were conducted at flowering (June) and fructification stages (August). Severity was evaluated with a 6-class logarithmic-diagrammatic scale setup in App-Monitor® v1.1. Genotype health was determined using an Integrated Damage Index (IDI), weighted and adjusted for disease severity and coverage-plant vigor (IV), which was estimated with images (RGB, 14mpx) captured with dron-Phantom-3 at 5 m height from genotype centroid. In SAS v9.4, t-test and ANOVAs, followed by Tukey (p = 0.05), were performed for different experimental settings. Disease spatial patterns were analyzed with kriging and omnidirectional variograms in SURFER v10. Forty-three total samples were used for isolation, pathogenicity testing, and molecular identification with universal primers ITS1/ITS4, NIb2F/NIb3R, PBL1v2040/PCR1c for eukaryotes, Potyvirus and Begomovirus, respectively. Final data matrix included 22 variables, 859 observations and 18,898 metadata. Alternaria alternata and Bean common mosaic virus (BCMV) were identified in 100% of samples analyzed with 99% homology. Vaquita Negro, Garrapato and Canario were statistically the most susceptible genotypes (37.3 - 58% severity) for BCMV, while Canario and Tipo Flor de Mayo (41.4-42.7%) were for A. alternata (p = 0.05). Oti and Negro Perla had higher climatic adaptability and tolerance to both pathogens with IV > 0.7 and IDI < 0.43. Spatially, BCMV presented random dispersion of foci and a block-edge effect with continuous contagion of up to 5.6 meters. Vaquita Negro and Bayo Mecentral showed uniform virus spread, presumptively due to high viral transmissibility by seed. In contrast, except for Tipo Flor de Mayo and Canario, which exhibited significant coalescence of foci, A. alternata had spatial dependence of less than 8 plants. Wind and hail damage significantly favored A. alternata infection (p = 0.05) suggesting its opportunistic condition.

Resumen. El objetivo de la investigación fue evaluar la respuesta fitosanitaria y comportamiento epidemiológico en 12 genotipos de Phaseolus vulgaris y desarrollar metodologías etiológico-epidemiológicas aplicables a estudios de mejoramiento genético. En ciclo primavera-verano 2020 se realizaron evaluaciones en fases de floración (junio) y fructificación (agosto). La severidad porcentual se evaluó con escala logarítmica-diagramática de 6-clases configurada en App-Monitor® v1.1. La sanidad por genotipo se determinó mediante un Índice de Daño Integrado (IDI), ponderando por intensidad de severidad y corregido por vigor de cobertura-planta (IV), calculado con imágenes (RGB, 14mpx) de dron-Phantom-3 a 5 m altura del centroide de genotipo. Se realizaron pruebas de t-Student (p = 0.05) y ANOVAs, seguido de Tukey (p = 0.05), con SAS v9.4 para las distintas variables experimentales. Se analizó la dependencia espacial de contagio con kriging y variogramas omnidireccionales en SURFER v10. Un total de 43 muestras se emplearon para aislamiento, pruebas de patogenicidad e identificación genómica con iniciadores universales ITS1/ITS4, NIb2F/NIb3R, PBL1v2040/PCR1c para eucariotes, Potyvirus y Begomovirus, respectivamente. La matriz final incluyó 22 variables, 859 observaciones y 18,898 metadatos. En 100% de muestras analizadas se identificó Alternaria alternata y Bean common mosaic virus (BCMV) con 99% de homología. Vaquita Negro, Garrapato y Canario fueron estadísticamente los genotipos más susceptibles (37.3 - 58% severidad) a BCMV, mientras Canario y Tipo Flor de Mayo (41.4 - 42.7%) a A. alternata (p < 0.05). Oti y Negro Perla presentaron mayor adaptabilidad climática y tolerancia a ambos patógenos con IV > 0.7 e IDI < 0.43. Espacialmente, BCMV presentó dispersión aleatoria de focos y efecto de bordo-bloque con contagios continuos de hasta 5.6 metros. Vaquita Negro y Bayo Mecentral tuvieron dispersión viral uniforme, presuntivamente por alta transmisibilidad viral por semilla. En contraste, con excepción en Tipo Flor de Mayo y Canario, que exhibieron coalescencia significativa de focos, A. alternata tuvo dependencia espacial menor a 8 plantas. El daño por viento y granizo significativamente favoreció la infección de A. alternata (p = 0.05) sugiriendo su naturaleza oportunista.

Resumo: O objetivo foi estimar a prevalência do atraso nas três doses da vacina tetravalente (DTP+Hib) em crianças de 12 a 23 meses de idade, no Brasil, por meio dos dados da Pesquisa Nacional de Saúde (PNS) de 2013 e descrever o atraso em cada uma das doses segundo variáveis sociodemográficas, utilização de serviços e intervenções públicas de saúde. Foram utilizados dados da PNS, estudo transversal realizado em 2013. O desfecho foi o atraso pelo menos em uma das três doses da vacina tetravalente. Considerou-se como atraso a dose recebida pelo menos 30 dias após a data preconizada, segundo informação da caderneta de vacinação. A prevalência do atraso foi descrita segundo variáveis sociodemográficas e utilização de serviços de saúde. Realizou-se análise descritiva obtendo-se frequências absolutas e relativas e seus respectivos intervalos de 95% de confiança. Das 2.016 crianças com informações coletadas, 1.843 foram analisadas. A prevalência de atraso de pelo menos uma dose da vacina foi de 44%. Observou-se atraso de 14,8% na primeira, 28,8% na segunda e 45,4% na terceira dose, sendo que 10% das crianças tiveram atraso nas três doses. Maiores prevalências de atraso foram encontradas em crianças do sexo masculino, de cor da pele parda, pertencentes ao quintil mais pobre de riqueza, moradores da zona rural e da Região Norte do Brasil. Evidenciou-se alta prevalência de atraso na vacina tetravalente (DTP+Hib) em crianças de 12 a 23 meses do Brasil, sendo maior na terceira dose.

Abstract: The study aimed to estimate the prevalence of delay in the three doses of quadrivalent vaccine (DTP+Hib) in children 12 to 23 months of age in Brazil, based on data from the Brazilian National Health Survey (PNS) of 2013 and to analyze the delay in each of the doses according to sociodemographic variables and use of health services and public health interventions. The data are from the PNS a cross-sectional study performed in 2013. The outcome was delay in at least one of the three doses of the quadrivalent vaccine. Delay was defined as a dose received at least 30 days after the recommended date according to information on the child’s vaccination card. Prevalence of delay was analyzed according to sociodemographic variables and use of health services. A descriptive analysis was performed to obtain absolute and relative frequencies and their respective 95% confidence intervals. Of the 2,016 children with information collected, 1,843 were analyzed. The prevalence of delay in at least one dose of the vaccine was 44%. There was a delay of 14.8% in the first dose, 28.8% in the second, and 45.4% in the third, and 10% of the children had delays in all three doses. Higher prevalence of delay was associated with male gender, brown skin color, the poorest income quintile, and residence in rural areas and the North of Brazil. The study revealed high prevalence of delay with the quadrivalent vaccine (DTP+Hib) in children 12 to 23 months of age in Brazil, with the highest delay in the third dose.

ABSTRACT This study assessed the technical performance of a rapid lateral flow immunochromatographic assay (LFIA) for the detection of anti-SARS-CoV-2 IgG and compared LFIA results with chemiluminescent immunoassay (CLIA) results and an in-house enzyme immunoassay (EIA). To this end, a total of 216 whole blood or serum samples from three groups were analyzed: the first group was composed of 68 true negative cases corresponding to blood bank donors, healthy young volunteers, and eight pediatric patients diagnosed with other coronavirus infections. The serum samples from these participants were obtained and stored in a pre-COVID-19 period, thus they were not expected to have COVID-19. In the second group of true positive cases, we chose to replace natural cases of COVID-19 by 96 participants who were expected to have produced anti-SARS-CoV-2 IgG antibodies 30-60 days after the vaccine booster dose. The serum samples were collected on the same day that LFIA were tested either by EIA or CLIA. The third study group was composed of 52 participants (12 adults and 40 children) who did or did not have anti-SARS-CoV-2 IgG antibodies due to specific clinical scenarios. The 12 adults had been vaccinated more than seven months before LFIA testing, and the 40 children had non-severe COVID-19 diagnosed using RT-PCR during the acute phase of infection. They were referred for outpatient follow-up and during this period the serum samples were collected and tested by CLIA and LFIA. All tests were performed by the same healthcare operator and there was no variation of LFIA results when tests were performed on finger prick whole blood or serum samples, so that results were grouped for analysis. LFIA’s sensitivity in detecting anti-SARS-CoV-2 IgG antibodies was 90%, specificity 97.6%, efficiency 93%, PPV 98.3%, NPV 86.6%, and likelihood ratio for a positive or a negative result were 37.5 and 0.01 respectively. There was a good agreement (Kappa index of 0.677) between LFIA results and serological (EIA or CLIA) results. In conclusion, LFIA analyzed in this study showed a good technical performance and agreement with reference serological assays (EIA or CLIA), therefore it can be recommended for use in the outpatient follow-up of non-severe cases of COVID-19 and to assess anti-SARS-CoV-2 IgG antibody production induced by vaccination and the antibodies decrease over time. However, LFIAs should be confirmed by using reference serological assays whenever possible.

Abstract This study evaluated the presence of oral lesions in patients with COVID-19 hospitalized in an intensive care unit (ICU). Data included demographic, clinical, and laboratory information. Clinical assessment of the oral cavity was performed on the 2 nd and 5 th days of orotracheal intubation. Thirty-eight patients were evaluated and 16 (42.1%) presented oral lesions during their ICU stay. The median age and length of stay were 75 years and 15 days, respectively. Among the patients with oral lesions, ulcerative oral lesions were reported in 14 (87.5%) patients, of which 11 (78.6%) were found on the lips. This study highlights the importance of oral examination for patients admitted to the ICU with COVID-19.

The study was performed in a pipe with an internal diameter of 3.8 mm and a length of 1000 mm, mass velocities varying between 197.59 and 267.26 kg·m−2 ·s−1 and heat flux between 72.83 and 488.27 W·m−2 ; during the experimental tests, an incident solar radiation between 0 and 652.9 W·m−2 was present. The Wojtan, Ursenbacher and Thome correlation was considered for the analysis and the model used does not require iterative calculations; moreover, it carries out a detailed analysis of the different zones present along the pipe. The predominant zones in this study are intermittent, annular and dryout, found in the five tests, however, due to the working conditions in all tests with the exception of test A, mist and stratified-wavy flow were found.

Resumen En la presente investigación se detallan los mapas de patrones de flujo que se generan en una tubería horizontal de un colector/evaporador componente de una bomba de calor de expansión directa asistida por energía solar, utilizando el refrigerante R600a como fluido de trabajo. El estudio se realizó en una tubería de 3,8 mm de diámetro interno y 1000 mm de longitud, las velocidades de masa variaron entre 197,59 y 267,26 kg·m−2 ·s −1, el flujo de calor entre 72,83 y 488,27 W·m−2 , durante las pruebas experimentales se presentó una radiación solar incidente entre 0 y 652,9 W·m−2 . Se consideró para el análisis la correlación de Wojtan, Ursenbacher y Thome, el modelo utilizado no requiere de cálculos iterativos, además, plantea un análisis detallado de las diferentes zonas presentes a lo largo de la tubería, evidenciando una mayor precisión en los resultados. Las zonas predominantes en los resultados de este estudio son intermitente, anular y secado, encontrados en las cinco pruebas, sin embargo, por las condiciones de trabajo en todas las pruebas a excepción de la prueba A, se encontró el flujo niebla y estratificado-ondulado.

Abstract. Adolescents face a variety of risk factors; however, familial context can provide protective factors that can reduce these risk factors, which makes understanding family context from the perspective of the adolescent critically important. This research presents item response theory indicators. The objective of the study was to generate validity and reliability indicators for parenting memories, family functionality, and prosocial parenting practices scales through Exploratory Factor Analysis with maximum likelihood and oblique, Rasch analysis and Confirmatory Factor Analysis. The sample consisted of 1,536 high school students from Sonora, Mexico of both sexes ranging from 12 to 15 years. Factor loading ranging from 0.52 to 0.80, Cronbach alphas were from 0.79 to 0.94, and CFI indicators were 0.92 to 0.95, RMSEA of 0.04 to 0.06 and SRMR of 0.02 to 0.05; invariance analysis demonstrated results were consistent for the different sexes and grade levels. The measures allow for greater specificity, particularly as it relates to relationships between household variables and the school context.

Resumen. En la adolescencia se presentan una diversidad de factores de riesgo, sin embargo, el contexto familiar puede proporcionar protección que disminuya dichos factores, de ahí la importancia de conocer el contexto familiar desde la perspectiva de los adolescentes. Es de nuestro interés presentar indicadores de validez y confiabilidad desde la teoría de respuesta al ítem. El objetivo fue generar indicadores de validez y confiabilidad para las escalas memorias de crianza, funcionalidad familiar y prácticas parentales prosociales a través del análisis factorial exploratorio con máxima verosimilitud y oblicua, análisis Rasch y análisis factorial confirmatorio. Participaron 1 536 estudiantes de secundaria del estado de Sonora, México, de ambos sexos con edades que oscilan entre los 12 a 15 años. Se obtuvieron cargas factoriales de 0.52 a 0.80, alfas de Cronbach de 0.79 a 0.94, CFI de 0.92 a 0.95, RMSEA de 0.04 a 0.06 y SRMR de 0.02 a 0.05; los resultados fueron consistentes para ambos sexos y grados según el análisis de invarianza. Los indicadores fueron óptimos en tres modelos para adolescentes. Estas medidas pueden utilizarse sobre todo cuando requerimos el entendimiento de las variables del hogar para explicar lo que sucede en el contexto escolar.

RESUMEN El objetivo fue dar a conocer los estudios que se han realizado desde el 2014 al 2019, donde se relacionan variables contextúales del estudiante de secundaria con la violencia escolar. Las bases de datos seleccionadas fueron SCOPUS, EBSCOhost y SciELO; se utilizaron términos afines al contexto familiar escolar y comunitario; se aplicaron filtros para acotar la búsqueda en acuerdo con los criterios de inclusión refiriendo a investigaciones arbitradas con diseño cuantitativo, causales, transversales en inglés o español en disciplinas de ciencias sociales. Resultaron 32 artículos que reflejan las variables de comunicación parental, clima escolar, exposición de violencia y apego a la comunidad, como las más relevantes para explicar violencia escolar Se concluyó en el consenso del modelo ecológico de Bronfenbrenner para involucrar conceptos de diferentes niveles factoriales de la violencia escolar ya que no se suele analizar elementos de los diversos contextos de manera conjunta. También se optó por realizar modelos causales que permitan predecir o identificar factores de riesgo y protección, incluyendo aspectos de comunidad. Por último, resalta la importancia de examinar al observador y aquellas variables que impulsan a defender a la víctima.

ABSTRACT The purpose of this review was to publicize the studies that have been carried out from 2014 to 2019 where contextual variables of the high school student are related to school violence. The selected databases were SCOPUS, EBSCOhost and SciELO where terms related to the family school and community context were used. Filters were applied to narrow the search according to the inclusion criteria referring to arbitrated research with a quantitative, causal, transversal design in English or Spanish in social science disciplines. 32 articles were found that showed that the most relevant variables to explain school violence were parental communication, school climate, exposure of violence and attachment to the community. It was concluded in the consensus of the Bronfenbrenner ecological model to involve concepts of different factorial levels of school violence, since elements from different contexts are not usually analyzed together: Also, is necessary to make causal models including community aspects that allows predict and identify risk and protector factors. Lastly, the importance of examining the bystander and those variables that drive to defend the victim.

RESUMO O objetivo era divulgar os estudos que foram realizados de 2014 a 2019, onde as variáveis contextuais do aluno do ensino médio estão relacionadas à violência escolar As bases de dados selecionadas foram SCOPUS, EBSCOhost e SciELO; foram utilizados termos relacionados ao contexto familiar escolar e comunitário; filtros foram aplicados para restringir a pesquisa de acordo com os critérios de inclusão referentes à pesquisa de referência com design quantitativo, causal, transversal em inglês ou espanhol em disciplinas de ciências sociais. Foram encontrados 32 artigos que refletem as variáveis de comunicação dos pais, clima escolar exposição à violência e apego à comunidade como os mais relevantes para explicar a violência escolar O consenso do modelo ecológico de Bronfenbrenner foi alcançado para envolver conceitos de diferentes níveis fatoriais de violência escolar uma vez que elementos de diferentes contextos não são geralmente analisados em conjunto. Também foi decidido desenvolver modelos causais que permitam prever ou identificar fatores de risco e proteção, incluindo aspectos da comunidade. Finalmente, destaca a importância de examinar o observador e aquelas variáveis que impulsionam a defesa da vítima.

Abstract Introduction: Allergic rhinitis is a chronic inflammatory disease of the nasal mucosa, mediated by immunoglobulin E, affecting 1 in 6 individuals. The treatment aims at attaining symptomatic control with minimal side effects, a requirement for new alternative therapies, including phototherapy, as it has an immunosuppressive and immunomodulatory effect. Objective: To identify the effectiveness of phototherapy in the treatment of allergic rhinitis through a meta-analysis. Methods: We searched Web of Science, Scielo, PubMed, SCOPUS, PEDro, and LILACS databases, using the terms: ‘‘intranasal irradiation’’, ‘‘phototherapy’’ and ‘‘allergic rhinitis’’. The R software Metafor package was used for the meta-analysis and the effect size was calculated for each symptom individually. Results: All symptoms decreased considerably after phototherapy: rhinorrhea (ES• = -1.35; p < 0.0001; I2 = 91.84%), sneezing (ES• = -1.24; p < 0.0001; I2 = 91.43%), nasal pruritus (ES• = -1.10; p < 0.0001; I2 = 91.43%); nasal obstruction (ES• = -1.11; p < 0.0001; I2 = 91.88%). The effects were more significant in perennial allergic rhinitis than in the seasonal type. Conclusion: Considering the effect size and the statistical significance attained in our study, rhinophototherapy showed to be an effective treatment for reducing the nasal symptom scores triggered by AR.

Resumo Introdução: A rinite alérgica é uma doença inflamatória crônica da mucosa nasal, imunomediada por imunoglobulina E, que afeta 1/6 dos indivíduos. O tratamento visa o controle dos sintomas com efeitos colaterais mínimos, uma prerrogativa para novas terapias alternativas, como a fototerapia, por apresentar efeitos imunossupressor e imunomodulador. Objetivo: Identificar, mediante uma metanálise, a eficácia da fototerapia no tratamento da rinite alérgica. Método: Usamos as bases de dados: Web of Science, Scielo, PubMed, SCOPUS, PEDro e LILACS, com os termos de busca: intranasal irradiation, phototherapy, allergic rhinitis. Para a metanálise foi usado o pacote metafor do software R, o tamanho do efeito foi calculado para cada sintoma separadamente. Resultados: Todos os sintomas apresentaram diminuição significante após a fototerapia: coriza (ES =-1,35; p < 0,0001; I2 = 91,84%), espirros (ES =-1,24; p < 0,0001; I2 = 91,43%), prurido nasal (ES =-1,10; p < 0,0001; I2 = 91,43%); obstrução nasal (ES =-1,11; p < 0,0001; I2 = 91,88%), com efeitos mais expressivos na rinite alérgica perene do que na rinite alérgica sazonal. Conclusão: Considerando-se a magnitude do efeito e a significância estatística alcançadas em nosso estudo, a rinofototerapia demonstrou-se um tratamento eficaz para a redução dos escores dos sintomas nasais desencadeados pela rinite alérgica.

ABSTRACT: This article attempts to analyze musicologist Pablo Garrido Vargas (1905-1982) approaches to Chilean cueca and explain how, despite being an intellectual committed to political projects by center-left coalitions, such as Frente Popular and Unidad Popular, his last book was published in 1979, under Pinochet's civilian-military dictatorship patronage. The article proposes that this particular context, Garrido’s personal situation at the time, and the nature of the dictatorship's cultural policies would explain this fact.

RESUMEN: Este artículo analiza los planteamientos del musicólogo Pablo Garrido Vargas (1905-1982) sobre la cueca chilena y explica cómo, a pesar de ser un intelectual comprometido con los proyectos políticos del Frente Popular y la Unidad Popular, su último libro fue publicado con el patrocinio de la dictadura civil-militar de Pinochet, en 1979. El artículo propone que el contexto, la situación personal de Garrido y el carácter de las políticas culturales de la dictadura, explican este hecho.
