Impacto de la pandemia por SARS-CoV-2 en el índice de masa corporal de niños asistidos en la Ciudad Autónoma de Buenos Aires / Impact of the SARS-CoV-2 pandemic on the body mass index of children seen in the City of Buenos Aires

Introducción. El sobrepeso y la obesidad infantil constituyen un problema de salud pública. El inicio de la pandemia por COVID-19 pudo haber favorecido esta patología. El puntaje Z del índice de masa corporal (Z-IMC) es un indicador aceptado para su diagnóstico y seguimiento. Objetivo. Evaluar si la prevalencia de sobrepeso y obesidad, y el Z-IMC en niños de 2 a 5 años aumentó durante la pandemia. Población y métodos. Estudio de cohorte retrospectiva. Se incluyeron pacientes asistidos en efectores públicos de salud del Gobierno de la Ciudad Autónoma de Buenos Aires (GCABA), de 2 a 5 años de edad, con registro de peso y talla en dos consultas, antes y después de haber comenzado el aislamiento social preventivo y obligatorio (ASPO). Se registró estado nutricional (Z-IMC) y variación del Z-IMC entre ambas consultas. Resultados. Se evaluaron 3866 sujetos, edad promedio 3,4 ± 0,8 años; el 48,1 % fueron mujeres. El intervalo promedio entre consultas fue 14,3 ± 2,5 meses. La prevalencia de sobrepeso/obesidad aumentó del 12,6 % (IC95% 11,6-13,6) al 20,9 % (IC95% 19,6-22-2); p <0,001, al igual que el Z-IMC (0,4 ± 1,1 vs. 0,8 ± 1,3; p <0,001). Conclusión. La prevalencia de sobrepeso y obesidad, y el Z-IMC en niños de 2 a 5 años aumentó significativamente durante la pandemia.

Introduction. Childhood overweight and obesity are a public health problem. The onset of the COVID-19 pandemic may have contributed to this condition. The body mass index (BMI) Z-score has been accepted as an indicator for overweight and obesity diagnosis and follow-up. Objective. To assess whether the prevalence of overweight and obesity and the BMI Z-score in children aged 2 to 5 years increased during the pandemic. Population and methods. Retrospective, cohort study. Patients included were those seen at public health care facilities in the City of Buenos Aires (CABA), who were aged 2 to 5 years, had weight and height values recorded at 2 different visits, before and after the establishment of the preventive and mandatory social isolation policy. Patients' nutritional status (BMI Z-score) and the variation in this indicator between both visits were recorded. Results. A total of 3866 subjects were assessed; their average age was 3.4 ± 0.8 years; 48.1% were girls. The average interval between both visits was 14.3 ± 2.5 months. The prevalence of overweight/ obesity increased from 12.6% (95% CI: 11.6­13.6) to 20.9% (95% CI: 19.6­22.2), p < 0.001, and so did the BMI Z-score (0.4 ± 1.1 versus 0.8 ± 1.3, p < 0.001). Conclusion. The prevalence of overweight and obesity and the BMI Z-score in children aged 2 to 5 years increased significantly during the pandemic.

Maternal overweight and obesity before pregnancy as predictors of childhood asthma in children under five years: a retrospective cohort in Peru / Sobrepeso y obesidad materna antes del embarazo como predictores de asma infantil en menores de cinco años: una cohorte retrospectiva en Perú

Abstract Objectives: to estimate the role of maternal overweight and obesity before pregnancy as predictors of childhood asthma in a population of Peruvian children under five years. Methods: we carried out a retrospective cohort study of children aged five years or less and their mothers from the Regional Hospital of Ayacucho and the María Auxiliadora Hospital in Lima, Peru. We included children who were born between 2013 and 2014 and follow them up until 2018 and 2019, respectively. The diagnosis of overweight and obesity of the mother before pregnancy and asthma in the child were registered in their clinical histories. Crude (cRR) and adjusted relative risks (aRR) and 95% confidence intervals (CI95%) were obtained using a generalized lineal model of the Poisson family with link log and robust variances. Results: we evaluated 431 medical records and found that 20.9% of the children had asthma, 26.7% of the mothers were overweight, and 20.2% were obese before pregnancy. In the adjusted regression model, overweight (aRR=2.94; CI95%= 1.54-5.60) and maternal obesity (aRR=5.10; CI95%= 2.73-9.51) were predictors of an increased risk of childhood asthma. Conclusions: maternal overweight and maternal obesity increased the risk of her children developing asthma threeand five-fold, respectively.

Resumen Objetivos: estimar el papel del sobrepeso y la obesidad materna antes del embarazo como predictores de asma infantil en una población de niños peruanos menores de cinco años. Métodos: realizamos un estudio de cohorte retrospectivo de niños de cinco años o menos y sus madres del Hospital Regional de Ayacucho y del Hospital María Auxiliadora de Lima, Perú. Se incluyeron niños nacidos entre 2013 y 2014 y se les dio seguimiento hasta 2018 y 2019, respectivamente. El diagnóstico de sobrepeso y obesidad de la madre antes del embarazo y asma en el niño fueron registrados en sus historias clínicas. Los riesgos relativos crudos (cRR) y ajustados (RRa) y los intervalos de confianza del 95% (IC95%) se obtuvieron mediante un modelo lineal generalizado de la familia de Poisson con log de enlace y varianzas robustas. Resultados: se evaluaron 431 historias clínicas y se encontró que el 20,9% de los niños tenían asma, el 26,7% de las madres tenían sobrepeso y el 20,2% eran obesas antes del embarazo. En el modelo de regresión ajustada, el sobrepeso (aRR=2,94; IC95%= 1,54-5,60) y obesidad materna (RRa=5,10; IC95%= 2,73-9,51) fueron predictores de un mayor riesgo de asma infantil. Conclusiones: el sobrepeso materno y la obesidad materna aumentaron tres y cinco veces el riesgo de que sus hijos desarrollaran asma, respectivamente.

Abstract Objective To analyze the prevalence and factors associated with hospitalization of elderly people with COVID-19 in the State of Paraná, PR, Brazil. Methods A cross-sectional study linked to the cohort "Longitudinal Monitoring of adults and elderly people who were discharged from hospital admission due to COVID-19", was carried out using information contained in the compulsory notification forms of the Notifiable Diseases Information System. Analyzes were carried out using relative and absolute frequencies, applying the chi-square test adopted in the logistic regression model. The study population included people aged 60 years or over and residing in the State of Paraná, who were hospitalized for COVID-19 from March 2020 to September 2021. Results A higher hospitalization prevalence was identified among elderly people with eight years of education or more. Individuals not vaccinated against COVID-19 had a greater chance of hospitalization. Males had a greater chance of admission to the Intensive Care Unit compared to females. Cardiovascular diseases, lung disease, and obesity have increased the prevalence of the severe form of the disease. Conclusion Factors such as education and non-adherence to vaccination against COVID-19 can increase the risk of hospitalization due to the disease. Elderly people of the male sex have a greater chance of hospitalization in the ICU compared to the female sex. Furthermore, not using antivirals can contribute to worsening health status.

Predictores del estado de salud funcional posingreso en cuidados intensivos en pacientes sépticos / Predictors of Post-Admission Functional Health Status in Intensive Care in Septic Patients

Introducción: Los pacientes críticos pediátricos son susceptibles de presentar alteraciones del flujo sanguíneo cerebral que impliquen un deterioro de su estado de salud funcional. Objetivo: Identificar factores predictores de mayor riesgo de mala evolución funcional en pacientes pediátricos críticos con sepsis. Métodos: Se realizó un estudio de cohortes retrospectivo con menores de 18 años de edad con sepsis, ingresados en la unidad de cuidados intensivos pediátricos. Se recogieron variables epidemiológicas, clínicas y del estado de salud funcional previas al ingreso, al alta y a los 6 meses. El estado de salud funcional se evaluó mediante la escala de categorías de estado global y cerebral pediátrico. Se evaluó el cambio del estado funcional entre el ingreso y a los 6 meses del alta. Se realizó un análisis univariante para comparar grupos considerando el mal pronóstico y el cambio del estado funcional y su relación con las variables. Resultados: Se incluyeron 46 pacientes. A los 6 meses del alta, cuatro (8,7 por ciento) presentaron mal pronóstico funcional y ocho (17,4 por ciento) empeoramiento funcional respecto al ingreso. No se encontraron asociaciones entre las variables predictoras y la morbilidad, aunque se observó cierta tendencia en algunas como mayor soporte inotrópico (VIS > 20: 12,5 por ciento vs. 50 por ciento, p= 0,075), extracorpóreo y de reemplazo renal (25 por ciento vs. 2,6 por ciento, p= 0,074) y estancia hospitalaria más prolongada (50 por ciento vs. 15,8 por ciento , p= 0,055). Conclusiones: El soporte en la unidad de cuidados intensivos pediátricos no fue un predictor de morbilidad funcional en la muestra(AU)

Introduction: Critically ill pediatric patients are susceptible to cerebral blood flow alterations that imply a deterioration of their functional health status. Objective: To identify predictors of a higher risk of poor functional outcome in critically ill pediatric patients with sepsis. Methods: A retrospective cohort study was conducted with children under 18 years of age with sepsis, who were admitted to the pediatric intensive care unit. Epidemiological, clinical, and functional health status variables were collected prior to admission, discharge, and after 6 months. Functional health status was assessed using the Pediatric Global State and Brain Status Category Scale. The change in performance status between admission and 6 months after discharge was assessed. A univariate analysis was performed to compare groups considering poor prognosis and change in functional status and their relationship with the variables. Results: A total of 46 patients were included. At 6 months after discharge, four (8.7 percent) had a poor functional prognosis and eight (17.4 percent) had functional worsening at admission. No associations were found between the predictor variables and morbidity, although some trends were observed in some variables, such as greater inotropic support (SIV > 20: 12.5 percent vs. 50 percent, p = 0.075), extracorporeal and renal replacement (25 percent vs. 2.6 , percent p = 0.074), and longer hospital stay (50 percent vs. 15.8 percent , p = 0.055). Conclusions: Support in the pediatric intensive care unit was not a predictor of functional morbidity in the sample(AU)

Immunization against covid-19 and mortality in hospitalized patients: a retrospective cohort / Imunização contra covid-19 e mortalidade em pacientes hospitalizados: coorte retrospectiva

ABSTRACT OBJECTIVE To evaluate the effectiveness of vaccines developed against covid-19 in reducing mortality in people hospitalized with severe acute respiratory syndrome (SARS) caused by SARS-CoV-2. METHODS This is a retrospective cohort that evaluated risk factors and the effectiveness of the two-dose vaccination schedule in reducing the mortality of people hospitalized for covid-19 in the state of Paraíba from February to November 2021. The explanatory variables were vaccination status, presence of comorbidities, socioeconomic and demographic characteristics. Descriptive analyses and bivariate and multivariable logistic regression were performed. RESULTS Most hospitalizations and deaths occurred until May 2021. The percentage of patients with a complete vaccination schedule was similar across patients admitted to public and private hospitals and higher in residents of less developed municipalities. Multivariable analysis demonstrated that women (OR = 0.896; 95%CI 0.830-0.967) and people admitted to private hospitals (OR = 0.756; 95%CI 0.679-0.842) were less likely to die. Presence of any comorbidity (OR = 1.627; 95%CI 1.500-1.765) and age ≥ 80 years (OR = 7.426; 95%CI 6.309-8.741) were risk factors for death. Patients with complete vaccination schedule at the time of admission were 41.7% less likely to die (OR = 0.583; 95% CI 0.501-0.679) from covid-19 in the adjusted analysis, as compared to unvaccinated patients. CONCLUSIONS The study reveals that immunization was effective in reducing the likelihood of death from covid-19. The results suggest that greater vaccination coverage in the first half of 2021 would prevent thousands of deaths in the country.

RESUMO OBJETIVO Avaliar a efetividade das vacinas desenvolvidas contra a covid-19 na redução da mortalidade em pessoas internadas com síndrome respiratória aguda grave (SRAG) causada pelo SARS-CoV-2. MÉTODOS Trata-se de uma coorte retrospectiva que avaliou fatores de riscos e a efetividade do esquema vacinal com duas doses na redução da mortalidade de pessoas internadas por covid-19 no estado da Paraíba entre fevereiro e novembro de 2021. As variáveis explicativas foram situação vacinal, presença de comorbidades, características socioeconômicas e demográficas. Foram realizadas análises descritivas e regressão logística bivariada e multivariável. RESULTADOS A maior parte das internações e óbitos ocorreram até maio de 2021. O percentual de pacientes com esquema vacinal completo foi similar entre pacientes internados em hospitais públicos e privados e superior em residentes de municípios com menor desenvolvimento. A análise multivariável demonstrou que mulheres (OR = 0,896; IC95% 0,830-0,967) e pessoas internadas em hospitais privados (OR = 0,756; IC95% 0,679-0,842) apresentaram menor chance de morte. A presença de alguma comorbidade (OR = 1,627; IC95% 1,500-1,765) e idade ≥ 80 anos (OR = 7,426; IC95% 6,309-8,741) foram fatores de risco de óbito. Pacientes com esquema vacinal completo no momento da internação apresentaram uma chance 41,7% menor de morte (OR = 0,583; IC95% 0,501-0,679) por covid-19 na análise ajustada, quando comparados com pacientes não vacinados. CONCLUSÕES O estudo revela que a imunização foi efetiva na redução da chance de óbito por covid-19. Os resultados sugerem que uma maior cobertura vacinal no primeiro semestre de 2021 evitaria milhares de mortes no país.

Risk of COVID-19 outcomes among healthcare workers: Findings from the Philippine CORONA retrospective cohort study

Objectives@#While many healthcare workers (HCWs) contracted COVID-19 during the pandemic, more information is needed to fully understand the potential for adverse health effects in this population segment. The aim of the present study is to examine the association between healthcare worker status and neurologic and clinical outcomes in COVID-19 infected inpatients.@*Methods@#Using the nationwide database provided by the retrospective cohort Philippine CORONA study, we extracted relevant data and performed a secondary analysis primarily focusing on the presentation and outcomes of healthcare workers. Propensity score matching in a 3:1 ratio was performed to match HCWs and non-HCWs. We performed multiple logistic and Cox regression analyses to determine the relationship between HCWs and COVID-19 clinical outcomes.@*Results@#We included 3,362 patients infected with COVID-19; of which, 854 were HCWs. Among the HCWs, a total of 31 (3.63%) and 45 (5.27%) had the primary outcomes of in-hospital mortality and respiratory failure, respectively. For both overall and 3:1 propensity-matched cohorts, being an HCW significantly decreased the odds of the following outcomes: severe/critical COVID-19 at nadir; in-hospital mortality; respiratory failure; intensive care unit admission; and hospital stay >14 days.@*Conclusion@#We found that being an HCW is not associated with worse neurologic and clinical outcomes among patients hospitalized for COVID-19.

Not only baseline but cumulative exposure of remnant cholesterol predicts the development of nonalcoholic fatty liver disease: a cohort study

BACKGROUND AND AIM@#Remnant cholesterol (remnant-C) mediates the progression of major adverse cardiovascular events. It is unclear whether remnant-C, and particularly cumulative exposure to remnant-C, is associated with nonalcoholic fatty liver disease (NAFLD). This study aimed to explore whether remnant-C, not only baseline but cumulative exposure, can be used to independently evaluate the risk of NAFLD.@*METHODS@#This study included 1 cohort totaling 21,958 subjects without NAFLD at baseline who underwent at least 2 repeated health checkups and 1 sub-cohort totaling 2,649 subjects restricted to those individuals with at least 4 examinations and no history of NAFLD until Exam 3. Cumulative remnant-C was calculated as a timeweighted model for each examination multiplied by the time between the 2 examinations divided the whole duration. Cox regression models were performed to estimate the association between baseline and cumulative exposure to remnant-C and incident NAFLD.@*RESULTS@#After multivariable adjustment, compared with the quintile 1 of baseline remnant-C, individuals with higher quintiles demonstrated significantly higher risks for NAFLD (hazard ratio [HR] 1.48, 95%CI 1.31-1.67 for quintile 2; HR 2.07, 95%CI 1.85-2.33 for quintile 3; HR 2.55, 95%CI 2.27-2.88 for quintile 4). Similarly, high cumulative remnant-C quintiles were significantly associated with higher risks for NAFLD (HR 3.43, 95%CI 1.95-6.05 for quintile 2; HR 4.25, 95%CI 2.44-7.40 for quintile 3; HR 6.29, 95%CI 3.59-10.99 for quintile 4), compared with the quintile 1.@*CONCLUSION@#Elevated levels of baseline and cumulative remnant-C were independently associated with incident NAFLD. Monitoring immediate levels and longitudinal trends of remnant-C may need to be emphasized in adults as part of NAFLD prevention strategy.

Incidence of Dental Caries and Associated Factors in the School Period in a Municipality in Southern Brazil

Abstract Objective: To estimate the incidence of dental caries and associated factors in the school period from six/seven to ten years of age. Material and Methods: A longitudinal study involving 168 children was followed up between 2015 and 2019 in the municipality of Palhoça, Brazil. The dependent variable was the caries incidence rate in the mixed dentition. The independent variables included information regarding demographic and socioeconomic status. Multivariate analyzes were carried out using Poisson Regression with a robust estimator. Variables with p <0.20 in the bivariate analysis were included in the adjusted model. Relative risks were estimated, as well as 95% confidence intervals. Results: Of 168 followed schoolchildren, 32 developed the disease, providing an incidence rate of 19.0%. Female children had a 10% higher risk [RR = 1.10 (95% CI 1.03; 1.18)] of developing caries than males. Also, children born from fathers with ≤ 8 years of schooling at baseline had a 9% higher risk [RR = 1.09 (95% CI 1.01; 1.16)] of developing dental caries compared to fathers with higher education. Conclusion: The incidence of dental caries in a four-year period was 19.0%. Females and children born from fathers with a lower level of education showed higher incidence rates.

Eficácia da ivermectina e atazanavir no tempo de recuperação dos sintomas de covid-19: uma coorte prospectiva / Effectiveness of ivermectin and atazanavir on time to resolution from covid-19 symptoms: a prospective cohort / Eficacia de ivermectina y atazanavir en el tiempo hasta lá resolución de los síntomas de covid-19: una cohorte prospectiva

Objetivo: avaliar a eficácia da Ivermectina e do Atazanavir em comparação com placebo no tempo de resolução dos sintomas e no tempo de duração da doença por COVID-19. Método: estudo observacional, de coorte prospectivo, longitudinal, descritivo e analítico com pacientes sintomáticos ambulatoriais, acompanhados por 06 meses em duas Unidades Básicas de Saúde para atendimento de COVID-19 em Teresina- Piauí, Brasil, no período de novembro a abril de 2021 identificados por amostragem aleatória 1:1:1. Foram realizados exames Reverse transcription polymerase chain reaction (RT-PCR) para confirmação laboratorial da suspeita de infecção pelo novo coronavírus e avaliação sociodemográfica e clínica. Resultados: dos 87 pacientes randomizados, 62,1% (n=54) eram do sexo masculino, com média de idade de 35,1 anos, possuíam companheira (53,9%), baixa renda (50,6%), eutróficos (40,7%) e sem comorbidades de saúde (78,2%). Não houve diferença entre o tempo médio para resolução dos sintomas, que foi de 21 dias (IQR, 8-30) no grupo atazanavir, 30 dias (IQR, 5-90) no grupo ivermectina em comparação com 14 dias (IQR, 9-21) no grupo controle. No dia 180, houve resolução dos sintomas em 100% no grupo placebo, 93,9% no grupo atazanavir e 95% no grupo ivermectina. A duração mediana da doença foi de 08 dias em todos os braços do estudo. Conclusão: o tratamento com atazanavir (6 dias) e ivermectina (3 dias) não reduziu o tempo de resolução dos sintomas e nem o tempo de duração da doença entre os pacientes ambulatoriais com COVID-19 leve em comparação com o grupo placebo. Os resultados não suportam o uso de ivermectina e atazanavir para tratamento de COVID-19 leve a moderado.

Objective: to evaluate the effectiveness of Ivermectin and Atazanavir compared to placebo in the time to resolution of symptoms and duration of illness due to COVID-19. Method: observational, prospective, longitudinal, descriptive and analytical cohort study with symptomatic outpatients, followed for 06 months in two Basic Health Units for COVID-19 care in Teresina-Piauí, Brazil, from November to April 2021 identified by 1:1:1 random sampling. Reverse transcription polymerase chain reaction (RT-PCR) tests were performed for laboratory confirmation of suspected infection with the new coronavirus and sociodemographic and clinical evaluation. Results: of the 87 randomized patients, 62.1% (n=54) were male, with a mean age of 35.1 years, had a partner (53.9%), low income (50.6%), eutrophic (40.7%) and without health comorbidities (78.2%). There was no difference between the median time to resolution of symptoms, which was 21 days (IQR, 8-30) in the atazanavir group, 30 days (IQR, 5- 90) in the ivermectin group compared with 14 days (IQR, 9- 21) in the control group. At day 180, there was resolution of symptoms in 100% in the placebo group, 93.9% in the atazanavir group, and 95% in the ivermectin group. The median duration of illness was 8 days in all study arms. Conclusion: Treatment with atazanavir (6 days) and ivermectin (3 days) did not reduce the time to symptom resolution or the duration of illness among outpatients with mild COVID-19 compared to the placebo group. The results do not support the use of ivermectin and atazanavir for the treatment of mild to moderate COVID-19.

Objetivo: evaluar la efectividad de Ivermectina y Atazanavir en comparación con placebo en el tiempo de resolución de los síntomas y duración de la enfermedad por COVID-19. Método: estudio de cohorte observacional, prospectivo, longitudinal, descriptivo y analítico con pacientes ambulatorios sintomáticos, seguidos durante 06 meses en dos Unidades Básicas de Salud para atención de COVID-19 en Teresina-Piauí, Brasil, de noviembre a abril de 2021 identificados por 1:1:1 muestreo aleatorio. Se realizaron pruebas de reacción en cadena de la polimerasa con transcriptasa inversa (RT-PCR) para confirmación de laboratorio de sospecha de infección por el nuevo coronavirus y evaluación sociodemográfica y clínica. Resultados: de los 87 pacientes aleatorizados, 62,1% (n=54) eran del sexo masculino, con una edad media de 35,1 años, tenían pareja (53,9%), bajos ingresos (50,6%), eutróficos (40,7%) y sin comorbilidades de salud (78,2%). No hubo diferencia entre la mediana de tiempo hasta la resolución de los síntomas, que fue de 21 días (RIC, 8-30) en el grupo de atazanavir, 30 días (RIC, 5- 90) en el grupo de ivermectina en comparación con 14 días (RIC, 9 - 21) en el grupo control. En el día 180, hubo una resolución de los síntomas del 100 % en el grupo de placebo, del 93,9 % en el grupo de atazanavir y del 95 % en el grupo de ivermectina. La mediana de duración de la enfermedad fue de 8 días en todos los brazos del estudio. Conclusión: El tratamiento con atazanavir (6 días) e ivermectina (3 días) no redujo el tiempo de resolución de los síntomas ni la duración de la enfermedad entre los pacientes ambulatorios con COVID-19 leve en comparación con el grupo placebo. Los resultados no respaldan el uso de ivermectina y atazanavir para el tratamiento de la COVID-19 de leve a moderada.

Concordância da avaliação da via alimentar entre fonoaudiólogo e médico baseado na escala FOIS: coorte retrospectiva / Agreement in the assessment of the food pathway between speech therapists and physicians based on the FOIS scale: a retrospective cohort study / Concordancia en la evaluación de la vía alimentaria entre fonoaudiólogos y médicos basada en la escala FOIS: un estudio de cohorte retrospectivo

Introdução: A avaliação fonoaudiológica hospitalar tem um importante papel na prevenção e manejo de pacientes com risco de broncoaspiração. No entanto, nem sempre cabe ao fonoaudiólogo a primeira avaliação e definição da via alimentar nos pacientes hospitalares. Objetivo: Comparar as decisões fonoaudiológicas e médicas quanto à viabilidade da via alimentar em um hospital geral e identificar fatores associados com a melhora da deglutição. Métodos: Trata-se de um estudo retrospectivo de pacientes internados em hospital em Joinville durante março a agosto de 2018. A via alimentar foi considerada com base na Functional Oral Intake Scale (FOIS) sendo a primeira decisão comparada entre o fonoaudiólogo e o médico para o mesmo paciente. Resultados: Dos 171 pacientes, houve maior concordância entre as condutas médica e fonoaudiológica para alimentação por sonda nasoenteral (SNE) (88,7%) e alimentação oral livre (81,9%). No entanto, houve apenas 35% de concordância na definição de dieta adaptada, sendo a concordância geral moderada (Kappa 0,486). Houve evolução na alimentação por via oral em 62 pacientes (36%). Maior limitação da via alimentar, verificado pela necessidade de SNE (OR = 3,17; p = 0,025) e o maior número de atendimentos fonoaudiológicos intra-hospitalares (OR = 1,09; p = 0,020) foram associados com a melhora da disfagia. Conclusão: Encontrou-se concordância entre a avaliação dietética de casos para uso de SNE ou dieta livre entre o fonoaudiólogo e médico. Uso de SNE, como indicador de gravidade do paciente, e o maior número de sessões de fonoterapia foram associados com a melhora da disfagia durante a internação. (AU)

Introduction: Hospital-based speech-language pathology plays a crucial role in preventing and managing patients at risk of bronchoaspiration. However, the initial evaluation and determination of the feeding route in hospitalized patients may not always fall under the responsibility of the speech-language pathologist. Objective: To compare the decisions of speech-language pathologists and medical professionals regarding the feasibility of the feeding route in a general hospital and identify factors associated with swallowing improvement. Methods: This is a retrospective study of patients admitted to a hospital in Joinville from March to August 2018. The feeding route was assessed based on the Functional Oral Intake Scale (FOIS), with the initial decision compared between the speech-language pathologist and the physician for the same patient. Results: Among 171 patients, there was higher agreement between medical and speech-language pathology decisions for nasoenteral tube feeding (88.7%) and oral unrestricted intake (81.9%). However, there was only 35% agreement in defining an adapted diet, with overall moderate agreement (Kappa 0.486). Oral feeding improved in 62 patients (36%). The presence of nasoenteral tube feeding (OR = 3.17; p = 0.025) and a higher number of in-hospital speech-language pathology appointments (OR = 1.09; p = 0.020) were identified as independent predictors for dysphagia improvement. Conclusion: Concordance was found in the dietary assessment for the use of nasoenteral tube feeding or oral unrestricted intake between speech-language pathologists and physicians. The use of nasoenteral tube feeding as an indicator of patient severity and a higher number of speech-language pathology sessions were associated with dysphagia improvement during hospitalization.

Introducción: La evaluación fonoaudiológica hospitalaria desempeña un papel crucial en la prevención y el manejo de pacientes con riesgo de broncoaspiración. Sin embargo, no siempre corresponde al fonoaudiólogo la primera evaluación y definición de la vía alimentaria en los pacientes hospitalizados.Objetivo: Comparar las decisiones fonoaudiológicas y médicas sobre la viabilidad de la vía alimentaria en un hospital general e identificar factores asociados con la mejora de la deglución. Métodos: Se trata de un estudio retrospectivo de pacientes hospitalizados en un hospital de Joinville durante marzo a agosto de 2018. La vía alimentaria se evaluó según la Escala Funcional de Ingesta Oral (FOIS), siendo la primera decisión comparada entre el fonoaudiólogo y el médico para el mismo paciente. Resultados: De 171 pacientes, hubo una mayor concordancia entre las decisiones médicas y fonoaudiológicas para la alimentación por sonda nasoenteral (SNE) (88,7%) y la alimentación oral libre (81,9%). Sin embargo, solo hubo un 35% de concordancia en la definición de una dieta adaptada, siendo la concordancia general moderada (Kappa 0,486). La alimentación oral mejoró en 62 pacientes (36%). Una mayor limitación de la vía alimentaria, indicada por la necesidad de SNE (OR = 3,17; p = 0,025), y un mayor número de sesiones fonoaudiológicas intrahospitalarias (OR = 1,09; p = 0,020) se asociaron con la mejora de la disfagia.Conclusión: Se encontró concordancia en la evaluación dietética para el uso de SNE o dieta libre entre el fonoaudiólogo y el médico. El uso de SNE, como indicador de la gravedad del paciente, y un mayornúmero de sesiones de fonoterapia se asociaron con la mejora de la disfagia durante la hospitalización. (AU)

Prevalence of IgA anti-tissue transglutaminase antibody in a cohort of iranians patients with inflammatory bowel disease

Background and Aims: Some studies have reported the coexistence of inflammatory bowel disease (IBD) and celiac disease (CD). However, the prevalence of anti-tissue transglutaminase antibodies (IgA and IgG) and their screening value in patients with IBD is not yet clear. This study aimed to assess the prevalence of IgA anti-tTG and its potential correlation with disease status in patients with IBD. Materials and Methods: This cross-sectional study was conducted on 110 patients with confirmed IBD diagnosis at Ghaem Hospital, Mashhad, Iran. For each patient, all demographic and clinical data including age, extra intestinal manifestations, underlying diseases, types of diseases, and surgical history were collected. IgA anti-tissue transglutaminase titers were assessed by enzyme-linked immunosorbent assay. Results: None of the patients with IBD were positive for IgA anti-tTG antibodies, with a mean titer of 3.31 ± 1.3 AU/mL. Also, the mean titers were not associated with age, gender and various disease clinical features including the disease history, underlying disease, diagnosis type, extraintestinal manifestations, and surgery history. Conclusion: No significant prevalence pattern of IgA anti-tTG antibody was observed in patients with IBD. Accordingly, serological screening for CeD is not recommended in IBD patients, unless in a relevant clinical CeD suspicion. (AU)

Óbitos neonatais por enterocolite necrosante: estudo de coorte retrospectiva / Neonatal deaths from necrotizing enterocolitis: a retrospective cohort study / Muertes neonatales por enterocolitis necrozante: estudio de cohorte retrospectivo

Introdução:A enterocolite necrosante é uma doença que pode afetar o trato gastrointestinal de recém-nascidos,cujas manifestações clínicas podem ser caracterizadas por vômitos biliosos, sangue nas fezes, distensão abdominal, além de alterações nos parâmetros hemodinâmicos e instabilidade térmica. As populações mais vulneráveis a essa enfermidade são recém-nascidos de baixo peso,expostos ao ambiente de terapia intensiva neonatal. Objetivos: Identificar o perfil de recém-nascidos e os fatores maternos e neonatais associados à ocorrência de óbitos por enterocolite necrosante, em maternidade de referência do Ceará-Brasil. Metodologia: Trata-se de coorte retrospectiva, estudo que objetiva a descrição da incidência de determinado evento ao longo do tempo, além do estabelecimento de relações causais entre os fatores associados ao acontecimento. Incluíram-serecém-nascidos que tiveram óbitos por enterocolite necrosante entre 2019 e 2021, comficha de investigação de óbitos neonatais preenchida corretamente, não sendo excluído nenhum recém-nascido, totalizando amostra de 29 óbitos.Resultados: Identificou-se que o perfil dos recém-nascidos foi,em maioria, deprematuros e com baixo peso e fatores de risco para outras doenças associadas,como a sepse, o que acarretourealização de procedimentos invasivos e internação em ambiente de terapia intensiva neonatal.Conclusões: A prematuridade e o baixo peso ao nascer foram as variáveis relevantes no estudo e podem estar associadas à piora das condições clínicas do recém-nascido e ao desenvolvimento de enterocolite necrosante (AU).

Introduction: Necrotizing Enterocolitis is a disease that can affect the gastrointestinal tract of newborns, whose clinical manifestations can be characterized by bilious vomiting, blood in stool, abdominal distension, in addition to changes in hemodynamic parameters and thermal instability. The populations most vulnerable to this disease are low birth weight newborns exposed to the neonatal intensive care environment. Objectives: This study aimed to identify the profile of newborns and maternal and neonatal factors associated with the occurrence of deaths from necrotizing enterocolitis in a reference maternity hospital in Ceará, Brazil. Methodology: This is a retrospective cohort study seeking to describe the incidence ofa particular event over time, as well as establish causal relationships between the factors associated with the event. The study population comprised newborns who died from necrotizing enterocolitis between 2019 and 2021, who had neonatal death investigation forms filled out correctly, with no newborns being excluded, totaling a sample of 29 deaths. Results: It was identified that the profile of newborns was mostly premature, of low birth weight and with risk factors for other associated diseases such as sepsis, leading to invasive procedures and hospitalization in a neonatal intensive care environment. Conclusions: Prematurity and low birth weight were relevant variables in the study and may be associated with worsening of the newborn's clinical conditionsand development of necrotizing enterocolitis (AU).

Utilidad del lavado broncoalveolar para la detección microbiológica, y factores asociados, en receptores de trasplante de precursores hematopoyéticos: estudio de cohorte retrospectivo / Usefulness of bronchoalveolar lavage for microbiological detection and asssociated factors in hematopoietic stem cell transplant receivers: a retrospective cohort study

INTRODUCCIÓN: Las opacidades pulmonares en receptores de trasplante de precursores hematopoyéticos (TPH) representan un desafío diagnóstico y son una causa de morbimortalidad. Existen grandes discrepancias con respecto a la sensibilidad diagnóstica del lavado broncoalveolar (LBA), sus complicaciones, y los factores asociados a la identificación microbiológica. OBJETIVO: Conocer la utilidad del estudio microbiológico del LBA en el diagnóstico, modificación de la conducta médica y estimar las complicaciones y mortalidad asociada al procedimiento, en receptores de TPH con opacidades pulmonares. PACIENTES Y MÉTODOS: Estudio de cohorte, retrospectivo, en adultos receptores de TPH a los que se les realizó una broncoscopía con LBA por presentar opacidades pulmonares, en el Hospital Italiano de Buenos Aires entre el 01/01/2011 y el 31/12/2020. RESULTADOS: De los 189 procedimientos analizados, en 79 se logró un hallazgo microbiológico (41,8%) y 122 permitieron modificar la conducta médica (64,6%). En 11 casos se observaron complicaciones graves dentro de las 12 horas (5,8%) de efectuado el LBA. La mortalidad intrahospitalaria fue de 16,8% (N = 21/125). El valor de neutrófilos en sangre previo al LBA (p = 0,037) y la presencia de nódulos pulmonares como lesión tomográfica predominante (p = 0,029) se asociaron independientemente al hallazgo microbiològico global. CONCLUSIONES: Nuestra investigación apoya la realización del LBA como herramienta diagnóstica en pacientes que reciben un TPH y presentan opacidades pulmonares.

BACKGROUND: Lung opacities are a cause of morbimortality in bone marrow transplant patients, and represent a diagnostic challenge. There are large discrepancies regarding the diagnostic sensitivity of bronchoalveolar lavage (BAL), its complications, and the factors associated with microbiological detection. AIM: To know the usefulness of the microbiological study of BAL in the diagnosis, in the modification in medical behavior and to estimate the complications and associated mortality of this diagnostic procedure in patients transplanted with hematopoietic progenitor cells with pulmonary opacities. METHODS: Retrospective cohort study in bone marrow transplant adult patients who underwent bronchoscopy with BAL due to lung opacities at Hospital Italiano de Buenos Aires between 01/01/2011 and 12/31/2020. RESULTS: Of the 189 BAL analyzed, 79 presented a microbiological detection (41.8%) and 122 allowed to modify the medical behavior (64.6%). Severe complications were observed within 12 hours after the procedure in11 cases (5.8%). In-hospital mortality was 16,8% (N = 21/125). The value of blood neutrophils prior to bronchoalveolar lavage (p = 0.037) and the presence of pulmonary nodules as the predominant tomographic lesion (p = 0.029) were independently associated with global microbiological detection. CONCLUSION: Our research supports the performance of BAL as a diagnostic tool in bone marrow transplant patients with lung opacities.

O uso de métodos contraceptivos hormonais em pacientes com asma: repercussões clínicas / The use of hormonal contraceptives methods in patients with asthma: clinical repercussions

Objetivo: Analisar o uso dos contraceptivos hormonais em mulheres com asma e a escolha desses métodos contraceptivos para essa população, com avaliação de eventuais repercussões sobre novos episódios de asma e sibilos. Métodos: Foram selecionados estudos longitudinais, ensaios clínicos, revisões sistemáticas e metanálises. As plataformas consultadas foram PubMed, Embase, Cochrane e SciELO, com a utilização dos descritores: "contracepção", "contracepção hormonal", "sistema intrauterino liberador de levonorgestrel" e "asma". Resultados: Dois grandes estudos demonstraram que o uso de contraceptivos hormonais esteve associado à redução do risco de novos episódios de asma. Uma revisão sistemática concluiu que os resultados para o uso de contraceptivos hormonais para mulheres com asma foram mistos, com aumento ou redução dos seguintes riscos: novo episódio de asma e aumento da frequência das crises e dos sibilos. O uso da contracepção hormonal em pacientes obesas portadoras de asma é controverso. Conclusão: Os resultados para o uso de contraceptivos hormonais em mulheres com asma são inconsistentes, com relatos de aumento ou de redução do risco de novos episódios. O uso do método contraceptivo deve ser discutido individualmente, levando-se em consideração outros fatores de risco associados e o desejo da mulher. A paciente deverá ser orientada se houver piora dos sintomas clínicos de asma na vigência do uso de qualquer método contraceptivo hormonal.

Objective: To analyze the use of hormonal contraceptives in women with asthma and the choice of this contraceptive method for this population, evaluating possible repercussions on new episodes of asthma and wheezing. Methods: Longitudinal studies, clinical trials, systematic reviews and meta-analyses were selected. Platforms consulted: PubMed, Embase, Cochrane, SciELO, using the descriptors: "contraception", "hormonal contraception", "levonorgestrel-releasing intrauterine system" and "asthma". Results: Two large studies demonstrated that the use of hormonal contraceptives was associated with a reduced risk of new episodes of asthma. A systematic review concluded that the results for the use of hormonal contraceptives for women with asthma were mixed, with increased or decrease in the following risks: new asthma episodes, increased frequency and wheezing. The use of hormonal contraception in obese patients with asthma is controversial. Conclusion: The results for the use of hormonal contraceptives in women with asthma are inconsistent, with reports of increased or reduced risk of new episodes. The use of the contraceptive method should be discussed individually, taking into account other associated risk factors and the woman's desire. The patient will be advised if there is a worsening of the clinical symptoms of asthma while using any hormonal contraceptive method.

INTRODUCCIÓN: Los pacientes hospitalizados con COVID-19 presentan un espectro clínico variable y su gravedad puede ser predicha por la presencia de factores de riesgo. OBJETIVO: Determinar los factores asociados al ingreso a UCI en pacientes internados por COVID-19 en Colombia. PACIENTES Y MÉTODOS: Estudio de cohorte multicéntrico, retrospectivo, en pacientes adultos hospitalizados por COVID-19 en Colombia, desde marzo de 2020 a enero de 2021. Se describieron las características de los pacientes y se establecieron predictores de ingreso a la UCI mediante un modelo de regresión logística. RESULTADOS: Se incluyeron 1.160 pacientes, edad media de 55 años, 59,7% fueron hombres y 426 pacientes (36,7%) ingresaron a UCI. Los factores asociados al ingreso a UCI fueron edad (OR 1,25; IC 95%: 1,14-1,37), sobrepeso (OR 2,82; IC 95%: 1,98-4,02) y obesidad (OR 2,97; IC 95%: 2,03-4,37), antecedente de cardiopatía valvular (OR 6,46; IC 95%: 1,84-27,48), hipotensión arterial al ingreso (OR 2,35; IC 95%: 1,40-3,97), SIRS (OR 2,03; IC 95%: 1,50-2,74), disnea (OR 1,52; IC 95%: 1,09-2.14), requerimiento de oxígeno (OR 2,64; IC 95%: 1,67-4,30), neutrofilia (OR1,09; IC 95%: 1,05-1,13), elevación de dímero D (OR 1,09; IC 95%: 1,03-1,18), compromiso multilobar (OR 2,19; IC 95%: 1,58-3,07) y consolidación pulmonar (OR1,52; IC 95%: 1,13-2,04). La mortalidad intrahospitalaria fue de 14,4% (166 pacientes), 2,3% entre los que no ingresaron a la UCI y 35,2% entre los que sí lo hicieron. CONCLUSIÓN: El 36,7% de pacientes hospitalizados por COVID-19 ingresó a UCI, identificándose predictores clínicos y de laboratorio asociados con este desenlace. La elaboración de modelos predictores con estos parámetros podría mejorar el pronóstico de los pacientes con COVID-19 que se hospitalizan.

BACKGROUND: Hospitalized patients with COVID-19 present a variable clinical spectrum and its severity might be predicted by the presence of risk factors. AIM: To determine the factors associated with ICU admission in patients hospitalized for COVID-19 in Colombia. METHOD: Retrospective multicenter cohort study, in adult patients hospitalized for COVID-19 in Colombia, from March 2020 to January 2021. Population characteristics were described and ICU admission predictors were established using a logistic regression model. RESULTS: 1,160 patients were included, mean age 55 years, 59.7% were men and 426 patients (36.7%) were admitted to the ICU. The associated factors were age (OR 1.25, 95% CI: 1.14-1.37), overweight (OR 2.82, 95% CI: 1.98-4.02) and obesity (OR 2.97, 95% CI: 2.03-4.37), valvular heart disease (OR 6.46, 95% CI: 1.84-27.48) hypotension at admission (OR 2.35, 95% CI: 1.40-3, 97), SIRS (OR 2.03, 95% CI: 1.50-2.74), dyspnea (OR 1.52, 95% CI: 1.09-2.14), oxygen requirement (OR 2.64, 95% CI: 1.67-4.30), neutrophilia (OR 1.09, 95% CI: 1.05-1.13), elevated D-dimer (OR 1.09, 95% CI: 1.03-1.18), multilobar lung involvement (OR 2.19, 95% CI: 1.58-3.07) and pulmonary consolidation (OR 1.52, 95% CI: 1.13-2.04). In-hospital mortality was 14.4% (166 patients), 2.3% among those that did not enter to the ICU and 35.2% among those who did. CONCLUSION: 36.7% of patients hospitalized for COVID-19 were admitted to the ICU. We identified clinical predictors associated with this outcome. Predictive models using these parameters could improve the prognostic of those patients with COVID-19 that are hospitalized.

Recomendações para o rastreamento do câncer de mama no Brasil do Colégio Brasileiro de Radiologia, da Sociedade Brasileira de Mastologia e da Federação Brasileira das Associações de Ginecologia e Obstetrícia / Recommendations for breast cancer screening in Brazil from the Brazilian College of Radiology, the Brazilian Society of Mastology and the Brazilian Federation of Gynecology and Obstetrics Associations

Objetivo: Apresentar a atualização das recomendações do Colégio Brasileiro de Radiologia e Diagnóstico por Imagem, da Sociedade Brasileira de Mastologia e da Federação Brasileira das Associações de Ginecologia e Obstetrícia para o rastreamento do câncer de mama no Brasil. Materiais e Métodos: Foram feitas buscas das evidências científicas publicadas nas bases Medline, EMBASE, Cochrane Library, EBSCO, CINAHL e Lilacs, entre janeiro de 2012 e julho de 2022. As recomendações foram baseadas nessas evidências, mediante consenso da comissão de especialistas das três entidades. Recomendações: O rastreamento mamográfico anual é recomendado para as mulheres de risco habitual entre 40 e 74 anos. Acima de 75 anos, deve ser reservado para as que tenham expectativa de vida maior que sete anos. Mulheres com risco maior que o habitual, entre elas as com mamas densas, com história pessoal de hiperplasia lobular atípica, carcinoma lobular in situ clássico, hiperplasia ductal atípica, tratamento de câncer de mama ou de irradiação no tórax antes dos 30 anos ou, ainda, portadoras de mutação genética ou com forte história familiar, beneficiam-se do rastreamento complementar, sendo consideradas de forma individualizada. A tomossíntese é uma evolução da mamografia e deve ser considerada no rastreamento, sempre que acessível e disponível. (AU)

Objective: To present the update of the recommendations of the Brazilian College of Radiology, the Brazilian Society of Mastology and the Brazilian Federation of Gynecology and Obstetrics Associations for breast cancer screening in Brazil. Materials and Methods: Scientific evidence published in Medline, Embase, Cochrane Library, Ebsco, Cinahl and Lilacs between January 2012 and July 2022 was searched. Recommendations were based on this evidence, by consensus of the expert committee of the three entities. Recommendations: Annual mammographic screening is recommended for women aged between 40 and 74 years old. Above 75 years should be reserved for those with a life expectancy greater than seven years. Women at higher than usual risk, including those with dense breasts, a personal history of atypical lobular hyperplasia, classic lobular carcinoma in situ, atypical ductal hyperplasia, treatment for breast câncer, chest irradiation before age 30, carriers of genetic mutation or with a strong family history, benefit from complementary screening, being considered individually. Tomosynthesis is an evolution of mammography and should be considered in screening, whenever accessible and available. (AU)

COVID-19 en trabajadores activos durante la cuarentena. Realidad de un sector urbano de Caracas, Venezuela / COVID-19 in active workers during quarantine. Reality of an urban sector of Caracas, Venezuela

La pandemia por COVID-19 resultó un problema para la salud pública mundial, que impactó particularmente al sector de trabajadores que debían trabajar y estar expuestos durante el periodo de cuarentena. Objetivo, analizar la incidencia de COVID-19 y sus características en trabajadores(as) activos(as) durante 34 semanas. Investigación descriptiva y transversal. Población constituida por todos los trabajadores(as) activos de sectores priorizados, con diagnóstico confirmado de COVID-19. De los 1.186 casos confirmados, 658 casos (55%) correspondió a trabajadores activos, una incidencia de 1,7 casos x 1000 (mayor a la esperada), con predominio en trabajadores(as) del sector salud (267casos), choferes del transporte y trabajadores de funerarias (253 casos). El 68,7% menor de 40 años y predominio del sexo masculino (61,2%). En el personal de salud, el 30% correspondió a personal de enfermería y 22% en médicos. La tasa de mortalidad en la población de trabajadores activos fue de 0,07 x cada 1000, con un índice de mortalidad de 0,05 y un índice de recuperación del 95,5%, comportamiento similar al de la población general. Sin embargo, la tasa de letalidad (trabajadores activos positivos fallecidos) fue del 4,4% (29 casos), donde el 75% (22/29) fueron enfermeras y médicos, lo que confirmó al sector salud y trabajadores(as) de servicios, como población trabajadora altamente expuesta y vulnerable, lo que justificó priorizar las medidas de prevención en estos trabajadores, al iniciar el sistema de vigilancia epidemiológica, la vacunación y la dotación con uso adecuado de la protección personal(AU)

The COVID-19 Pandemic was a problem for global public health, which particularly impacted the sector of workers who had to work and were exposed during the quarantine period. The objective was to analyze the incidence of COVID- 19 and its characteristics in active workers during 34 weeks. Descriptive and cross-sectional research. Population made up of all active workers in prioritized sectors, with a confirmed diagnosis of COVID-19. Of the 1,186 confirmed cases, 658 cases (55%) corresponded to active workers, an incidence of 1.7 cases per 1,000 (higher than expected), with a predominance of workers in the health sector (267 cases), transport drivers and funeral home workers (253 cases). 68.7% under 40 years of age and predominance of the male sex (61.2%). In health personnel, 30% corresponded to nursing personnel and 22% to doctors. The mortality rate in the population of active workers was 0.07 x every 1000, with a mortality rate of 0.05 and a recovery rate of 95.5%, behavior similar to that of the general population. However, the fatality rate (deceased positive active workers) was 4.4% (29 cases), where 75% (22/29) were nurses and doctors, which confirmed the health sector and service workers, as a highly exposed and vulnerable working population, which justified prioritizing prevention measures in these workers, by initiating the epidemiological surveillance system, vaccination and provision with adequate use of personal protection(AU)

The efficacy of porcine dermal collagen to treat complex anal fistulae: results of a multicenter cohort

Introduction: The management of complex anal fistulae remains a topical surgical problem. The choice and success of surgical management are based on the balance between healing and continence. Although porcine dermal collagen (Permacol Collagen Paste [PCP]- Covidien plc, Gosport, Hampshire, UK) represents a new generation of non-solid biomaterials, its results in anal fistulae are mixed. Methods: A multicenter observational retrospective analysis of consecutive patients with cryptoglandular anal fistula treated in four colorectal surgery units was performed between 2015 and 2020. Clinical cure of the fistula was the main outcome measure. Adverse events and alterations in anal continence were secondary outcomes. Results: The study included 119 patients (87 males, 71.1%), with a mean age of 53 years (IR 44-65). Most patients had complex (80.6%) and recurrent (91.6%) fistulae. With the first PCP treatment, the overall cure rate was 41.2% (49 patients) and 45.4% with the second treatment (5 out of 17 patients). The mean follow-up period was 17 months (IR 5-25). Healing was not affected by the location and type of fistula, the existence or not of a cavity, the number of tracts, or the administration of prophylactic antibiotics. After the PCP treatment, no patient in the series had worsening of continence. Morbidity affected 22.7% of the patients (27), with postoperative abscesses being the most frequent adverse event. There were no statistical differences between the four hospitals studied. Conclusions: Permacol collagen paste is a safe and easily reproducible therapy for complicated anal fistulae that has moderate efficacy. The overall success rate is slightly over 40%, with no detriment to fecal continence. (AU)

Microorganismos aislados de hemocultivos en niños con leucemia y linforma: Seis años de seguimiento / Microorganisms isolated from blood cultures in children with leukemia and lymphoma: six years of follow-up

Las Leucemias y linfomas constituyen las enfermedades oncológicas más frecuentes en pediatría y las bacteriemias representan infecciones graves en estos pacientes. Objetivos: describir los microorganismos aislados de sangre en pacientes con leucemia aguda o linfoma pediátrico; comparar la incidencia de aislamientos según enfermedad de base; detallar las variaciones en la incidencia de dichos aislamientos y la evolución de su resistencia antimicrobiana. Estudio retrospectivo, observacional. Se incluyeron 823 episodios de bacteriemia en 467 pacientes pediátricos, entre julio-2016 y junio-2022, dividido en tres períodos (período-1: años 2016- 2018, período-2: años 2018-2020, período-3: años 2020-2022). Se aislaron 880 microorganismos: 55,3% gram negativos (GN), 40% gram positivos (GP) y 4,7% levaduras. En GN predominaron: enterobacterias (72%) y en GP: estreptococos del grupo viridans (SGV) (34,1%). Se encontró asociación entre LLA-enterobacterias (p=0,009) y LMA-SGV (p<0,001). Hubo aumento de GN entre los períodos 1 y 3 (p=0,02) y 2 y 3 (p=0,002) y disminución de GP entre 2 y 3 (p=0,01). Se registraron los siguientes mecanismos de resistencia: BLEE (16,4%), carbapenemasas: KPC (2,5%); MBL (2,7%) y OXA (0,2%); meticilinorresistencia en Staphylococcus aureus (20%) y estafilococos coagulasa negativos (95%), vancomicina resistencia en Enterococcus spp. (39%), SGV no sensibles a penicilina (44%) y a cefotaxima (13%). Hubo aumento de MBL entre los períodos 1 y 2 (p=0,02) y una tendencia en disminución de sensibilidad a penicilina en SGV entre el 1 y 3 (p=0,058). El conocimiento dinámico y análisis de estos datos es esencial para generar estadísticas a nivel local, fundamentales para el diseño de guías de tratamientos empíricos (AU)

Leukemias and lymphomas are the most common cancers in children and bacteremia is a severe infection in these patients. Objectives: to describe the microorganisms isolated from blood in pediatric patients with acute leukemia or lymphoma; to compare the incidence of isolates according to the underlying disease; and to detail the variations in the incidence of these isolates and the evolution of their antimicrobial resistance. Retrospective, observational study. We included 823 episodes of bacteremia in 467 pediatric patients seen between July-2016 and June-2022, divided into three periods (period-1: 2016- 2018, period-2: 2018-2020, period-3: 2020-2022). A total of 880 microorganisms were isolated: 55.3% were gram-negative (GN), 40% gram-positive (GP) and 4.7% yeasts. In GN there was a predominance of: enterobacteria (72%) and in GP viridans group streptococci (VGS) (34.1%). An association was found between ALL-enterobacteria (p=0.009) and AML-VGS (p<0.001). There was an increase in GN between periods 1 and 3 (p=0.02) and 2 and 3 (p=0.002) and a decrease in GP between 2 and 3 (p=0.01). The following resistance mechanisms were recorded: BLEE (16.4%), carbapenemases: KPC (2.5%), MBL (2.7%), and OXA (0.2%); methicillin resistance in Staphylococcus aureus (20%) and coagulase negative staphylococci (95%), vancomycin resistance in Enterococcus spp. (39%), VGS resistant to penicillin (44%) and to cefotaxime (13%). There was an increase in MBL between periods 1 and 2 (p=0.02) and a decreasing trend in penicillin sensitivity in VGS between periods 1 and 3 (p=0.058). Dynamic knowledge and analysis of these data is essential to generate statistics at the local level, which is fundamental for the design of empirical treatment guidelines (AU)

Sustancias psicoactivas, alumnos de anatomía y prepandemia COVID-19: prevalencia de uso y comparación de estudios transversales del periodo 2011-2019 / Psychoactive substances, anatomy and pre-pandemic COVID-19 students: prevalence of use and comparison of cross-sectional studies from the period 2011-2019

En estudios preliminares objetivamos alta prevalencia de uso de sustancias psicoactivas (SP) entre alumnos de Anatomía, con mayor impacto entre los recursantes o aquellos con actividades laborales. La causa del uso es multifactorial, pero se destacan factores de riesgo y precipitantes como la carga horaria de la currícula, exigencias de estudio, el distrés por el afrontamiento cadavérico negativo, el nuevo contexto educativo y la cantidad de horas de sueño. El objetivo fue comparar la prevalencia de uso de SP entre las cohortes de 2011-2019, con focalización en los factores determinantes conductuales. Estudio observacional, transversal y comparativo mediante encuesta estandarizada y anónima en 945 alumnos (año 2011= 122; año 2013= 158; año 2015=204; año 2017= 228; año 2019= 233). Se aplicaron parámetros estadísticos, se definió la significación como p -0.84; AA: r> -0.71). En el caso de ansiolíticos benzodiacepínicos, se asoció con falta de sueño y distrés por el afrontamiento negativo al estudio con cadáveres. En las cohortes comparadas por el lapso de 9 años hallamos alta prevalencia de uso de sustancias psicoactivas con tendencia al incremento. Las variables actividad laboral y recursante fueron determinantes para el uso de sustancias, y se asociaron cuestiones relativas a la adaptabilidad universitaria y afrontamiento de estudio negativo con el cadáver; todos con incidencia pedagógica en el proceso de enseñanza y aprendizaje.

SUMMARY: In preliminary studies, we observed a high prevalence of the use of psychoactive substances (PS) among Anatomy students, with a greater impact among recurrent students or those with work activities. The cause of use is multifactorial, but risk and precipitating factors stand out, such as the workload of the curriculum, study demands, distress due to negative cadaveric coping, the new educational context and the number of hours of sleep. The objective was to compare the prevalence of SP use between the 2011-2019 cohorts, with a focus on behavioral determinants. Observational, cross-sectional and comparative study using a standardized and anonymous survey in 945 students (year 2011= 122; year 2013= 158; year 2015=204; year 2017= 228; year 2019= 233). Statistical parameters were applied, significance was defined as p -0.84; AA: r> -0.71). In the case of benzodiazepine anxiolytics, it was associated with lack of sleep and distress due to negative coping with the study with cadavers. In the cohorts compared for a period of 9 years, we found a high prevalence of psychoactive substance use with an increasing trend. The variables work activity and recurrence were determinants for the use of substances, and issues related to university adaptability and negative study coping with the corpse were associated; all with pedagogical impact on the teaching and learning process.
