Improvement in intubation success during COVID-19 pandemic with a simple and low-cost intervention: A quasi-experimental study / Mejoría del éxito en la intubación durante la pandemia covid-19 con una intervención simple y de bajo costo: estudio cuasi-experimental

Objectives: primary objective: to improve the FPS rates after an educational intervention. Secondary objective: to describe variables related to FPS in an ED and determine which ones were related to the highest number of attempts.Design it was a prospective quasi-experimental study. Setting done in an ED in a public Hospital in Argentina. Patients there were patients of all ages with intubation in ED. Interventionsin the middle of the study, an educational intervention was done to improve FPS. Cognitive aids and pre- intubation Checklists were implemented. Main variables of interest the operator experience, the number of intubation attempts, intubation judgment, predictors of a difficult airway, Cormack score, assist devices, complications, blood pressure, heart rate, and pulse oximetry before and after intubation All the intubations were done by direct laryngoscopy (DL). Results data from 266 patients were included of which 123 belonged to the basal period and 143 belonged to the post-intervention period. FPS percentage of the pre-intervention group was 69.9% (IC95%: 60.89–77.68) whereas the post-intervention group was 85.3% (IC95%: 78.20–90.48). The difference between these groups was statistically significant (p=0.002). Factors related to the highest number of attempts were low operator experience, Cormack-Lehane 3 score and no training. Conclusions a low-cost and simple educational intervention in airway management was significantly associated with improvement in FPS, reaching the same rate of FPS than in high income countries.

Escorpionismo en pediatría: estudio descriptivo, transversal y retrospectivo de factores predictores de gravedad / Pediatric scorpionism: a descriptive, cross-sectional, and retrospective study of predictors of severity

Introducción. El emponzoñamiento por Tityus carrilloi n. sp. representa una amenaza para la vida. Según las manifestaciones clínicas, se clasifica en leve, moderado y grave. Objetivo. Comparar las características epidemiológicas y bioquímicas en niños con escorpionismo leve, moderado y grave. Población y métodos. Estudio descriptivo, transversal y retrospectivo. Se analizaron las consultas de menores de 15 años picados por Tityus carrilloi n. sp. entre enero de 2017 y diciembre de 2018 en un hospital pediátrico de tercer nivel en Santa Fe (Argentina). Resultados. Se incluyeron 524 niños, el 81 % (421) con dolor local y el 19 % (103) con manifestaciones sistémicas. Los niños con síntomas sistémicos de escorpionismo fueron más pequeños en edad que los que presentaron manifestaciones locales (p <0,001). En el invierno los niños desarrollaron 8 veces más manifestaciones sistémicas de escorpionismo y durante la primavera, 2,4 veces más que durante el verano. De los 103 niños internados, 80 fueron casos moderados y 23, graves. No hubo diferencias entre grupos en edad (p = 0,29) ni en la demora en recibir suero antiescorpiónico (p = 0,81). El tiempo de internación fue mayor en los graves (p <0,001). Los valores de glóbulos blancos o glucemia mayores a 30 000 cel/ml y 300 mg/dl respectivamente estuvieron presentes casi exclusivamente en escorpionismos graves. Conclusión. En niños picados por el escorpión Tityus carrilloi n. sp., el riesgo de desarrollar manifestaciones sistémicas fue mayor cuanto menor fue la edad y durante el invierno y la primavera. Los valores de glóbulos blancos y de glucemia fueron mayores en niños con escorpionismo grave.

Introduction. Scorpion envenomation by Tityus carrilloi n. sp. represents a threat to life. Depending on its clinical manifestations, it is classified as mild, moderate or severe. Objective. To compare the epidemiological and biochemical characteristics among children with mild, moderate, and severe scorpionism. Population and methods. Descriptive, crosssectional, and retrospective study. The consultations at a tertiary care children's hospital in Santa Fe (Argentina) of children under 15 years of age stung by Tityus carrilloi n. sp. between January 2017 and December 2018 were analyzed. Results. In total, 524 children were included, 81% (421) with local pain and 19% (103) with systemic manifestations. Children with systemic symptoms of scorpionism were younger in age than those with local manifestations (p < 0.001). In the winter, children developed 8 times more systemic manifestations of scorpionism; during the spring, 2.4 times more than during the summer. Out of the 103 hospitalized children, 80 were moderate cases and 23 severe cases. There were no differences between age groups (p = 0.29) or in the delay in receiving the anti-scorpion serum (p = 0.81). The length of hospital stay was longer among severe cases (p < 0.001). WBC and blood glucose levels higher than 30 000 cell/mL and 300 mg/dL, respectively, were present almost exclusively in severe scorpionism cases. Conclusion. In children stung by the scorpion Tityus carrilloi n. sp., the younger the age and during winter and spring, the higher the risk for systemic manifestations. WBC and blood glucose levels were higher in children with severe scorpionism.

Preceding anti-spike IgG levels predicted risk and severity of COVID-19 during the Omicron-dominant wave in Santa Fe city, Argentina.

The SARS-CoV-2 Omicron variant has increased infectivity and immune escape compared with previous variants, and caused the surge of massive COVID-19 waves globally. Despite a vast majority (~90%) of the population of Santa Fe city, Argentina had been vaccinated and/or had been infected by SARS-CoV-2 when Omicron emerged, the epidemic wave that followed its arrival was by far the largest one experienced in the city. A serosurvey conducted prior to the arrival of Omicron allowed to assess the acquired humoral defences preceding the wave and to conduct a longitudinal study to provide individual-level real-world data linking antibody levels and protection against COVID-19 during the wave. A very large proportion of 1455 sampled individuals had immunological memory against COVID-19 at the arrival of Omicron (almost 90%), and about half (48.9%) had high anti-spike immunoglobulin G levels (>200 UI/ml). However, the antibody titres varied greatly among the participants, and such variability depended mainly on the vaccine platform received, on having had COVID-19 previously and on the number of days elapsed since last antigen exposure (vaccine shot or natural infection). A follow-up of 514 participants provided real-world evidence of antibody-mediated protection against COVID-19 during a period of high risk of exposure to an immune-escaping highly transmissible variant. Pre-wave antibody titres were strongly negatively associated with COVID-19 incidence and severity of symptoms during the wave. Also, receiving a vaccine shot during the follow-up period reduced the COVID-19 risk drastically (15-fold). These results highlight the importance of maintaining high defences through vaccination at times of high risk of exposure to immune-escaping variants.

[Infant mortality and social inequalities in Argentina, 1980-2017]. / Mortalidad infantil y desigualdades sociales en Argentina, 1980-2017.

OBJECTIVE: To estimate the trend in infant mortality, inequality between jurisdictions and inequality associated with social conditions in Argentina between 1980 and 2017. METHODS: Ecological and time series study of infant mortality and its inequality. Official data on infant mortality, births and unmet basic needs were obtained; the infant mortality rate, the Gini index and the concentration index were calculated. The trend was also analyzed with a linear regression model and the regression coefficient and its statistical significance were calculated. RESULTS: Infant mortality was reduced by 71.2% (from 32.41 to 9.34 per 1 000 live births). Inequality by jurisdiction also decreased, and the Gini index fell from 0,163 to 0,09. Inequality associated with social conditions also showed a reduction, and the concentration index was reduced from -0.153 to -0.079. Although infant mortality declined throughout the period, this decline was not always accompanied by a reduction in the Gini index and the concentration index. CONCLUSIONS: The trend in the infant mortality rate decreased while the inequality in its distribution by jurisdiction and the inequality associated with social conditions did not always accompany this reduction.

Mortalidad infantil y desigualdades sociales en Argentina, 1980-2017

[RESUMEN]. Objetivo. Estimar la tendencia de la mortalidad infantil, de la desigualdad entre jurisdicciones y de la desigualdad asociada a las condiciones sociales en Argentina entre 1980 y 2017. Métodos. Estudio ecológico y de serie temporal de la mortalidad infantil y de su desigualdad. Se obtuvieron los datos oficiales de mortalidad infantil, de nacimientos y de necesidades básicas insatisfechas; se calculó la tasa de mortalidad infantil, el índice de Gini y el índice de concentración. También se analizó la tendencia con un modelo de regresión lineal y se calculó el coeficiente de regresión y su significación estadística. Resultados. La mortalidad infantil se redujo 71,2% (de 32,41 a 9,34 por 1 000 nacidos vivos). La desigualdad por jurisdicción también se redujo y el índice de Gini pasó de 0,163 a 0,09. La desigualdad asociada a las condiciones sociales también mostró una reducción, y el índice de concentración disminuyó de -0,153 a -0,079. Si bien la mortalidad infantil se redujo en todo el período, este descenso no siempre se acompañó de una reducción del índice de Gini y del índice de concentración. Conclusiones. La tendencia de la tasa de mortalidad infantil fue al descenso mientras que la desigualdad en su distribución por jurisdicción y la desigualdad asociada a las condiciones sociales no siempre acompañaron esa reducción.

Acceso y adherencia a la atención en patologías crónicas, atenciones pediátricas y embarazos, en Aislamiento Social Preventivo y Obligatorio / Access and adherence to care in chronic pathologies, pediatric care and pregnancies, in Preventive and Compulsory Social Isolation

La pandemia por el virus COVID-19 motivó a Argentina a adoptar medidas preventivas, enmarcadas en el Aislamiento Preventivo, Social y Obligatorio. El primer nivel de atención de salud se vio obligado a readaptarse para evitar la propagación de la enfermedad y proteger a grupos de riesgo como embarazadas, niños y pacientes con enfermedades crónicas, pero el impacto de esta medida de prevención en la atención primaria de la salud es aún desconocido en nuestro medio. El presente estudio pretende evaluar el acceso y adherencia a la atención adecuada de embarazadas, menores de 5 años y personas con Diabetes, Tuberculosis o Hipertensión en contexto de Aislamiento Social Preventivo y Obligatorio y sus factores asociados, en las ciudades de Santa Fe, Reconquista y Villa María. Se llevó a cabo un estudio transversal de una muestra proporcional de Centros de Atención Primaria de cada ciudad incluida en el estudio. Se utilizó fuentes secundarias de información de sistemas de vigilancia online y los registros digitales o papel de cada centro de atención. Variables seleccionadas referentes al acceso y adherencia a la atención fueron evaluadas en dos periodos; antes y durante el Aislamiento Preventivo Social y Obligatorio. Se realizó un análisis inferencial, comparando la media a través del test de las permutaciones y proporciones a través del test de Fisher. Finalmente se realizó un análisis multivariado de reducción de dimensiones mediante el método de componentes principales para variables cuantitativas y se agruparon los centros de salud con características similares

[Result of a strategy using reminders before and after date of vaccination to improve timeliness of vaccination at six month]. / Resultado de una estrategia de recordatorios previos y posteriores a la fecha de vacunación para mejorar la oportunidad de la vacunación a los seis meses.

The impact of immunization depends on timely application of the vaccines, especially relevant in children. Successful strategies for improving timeliness include the use of nominalized records and follow-up mechanisms. This study assessed the result of reminders before and after the scheduled date of vaccination to improve timely vaccination at six months. A before-and-after intervention study was performed with a time series and comparator group with 1,856 children from Villa María, Córdoba, Argentina. The strategy was implemented in the city's public services and consisted of preparing weekly vaccination schedules, performing follow-up, and contacting and/or making active searches for no-show cases. Assessment of the result used the percentage of timely vaccination with the third dose of the pentavalent vaccine. Time series were built for each group, before and after, and were analyzed with a simple linear model. Means of the percentages were calculated with their confidence intervals, using bootstrap, and compared with the permutation method. In the intervention group, the mean percentage of timely vaccination increased significantly by 2.6 times, reaching 61.7% (56.2; 78.1). No significant increase occurred in the comparator group: p = 0.1101. The mean rates were similar before the implementation. Timely vaccination improved in children receiving the intervention. The results indicate that the proposed strategy to use nominalized records can reduce the delay in application of vaccines.

El impacto de la inmunización depende de que las vacunas se apliquen oportunamente, aspecto aún más relevante en los niños. Las estrategias exitosas para mejorar la oportunidad incluyen el uso de registros nominalizados y mecanismos de seguimiento. En este estudio se evaluó el resultado del uso de recordatorios previos, y posteriores a la fecha de vacunación, para mejorar la vacunación oportuna a los seis meses. Se realizó un estudio de intervención antes-después, con serie cronológica y grupo de comparación, con 1.856 niños de Villa María, Córdoba, Argentina. La estrategia se implementó en los servicios públicos de la ciudad y consistió en confeccionar agendas de vacunación semanalmente, realizar el seguimiento y contactar y/o realizar búsqueda activa en los casos de no concurrencia. Para evaluar el resultado se utilizó el porcentaje de vacunados oportunamente con tercera dosis de quíntuple. Se construyeron series cronológicas para cada grupo, antes y después, y se analizaron con un modelo lineal simple. Se calculó la media de los porcentajes y sus intervalos de confianza utilizando bootstrap y se compararon con el método de permutaciones. En el grupo de intervención, la media del porcentaje de vacunación oportuna aumentó significativamente 2,6 veces, llegando a 61,7% (56,2; 78,1). En el de comparación no hubo un incremento significativo: p = 0,1101. Antes de la implementación sus medias eran similares. Se mejoró la vacunación oportuna de los niños bajo intervención. Los resultados indican que la estrategia propuesta para utilizar los registros nominalizados puede reducir la demora en la aplicación de las vacunas.

O impacto da imunização depende de quais vacinas se aplicaram no momento oportuno, característica ainda mais relevante nas crianças. As estratégias bem sucedidas para melhorar a oportunidade incluem o uso de registros nominalizados e mecanismos de monitoramento. Neste estudo foi avaliado o resultado da utilização de avisos prévios, e posteriores a data de vacinação, para melhorar a vacinação num prazo de seis meses. Foi realizado um estudo de intervenção antes e depois, com série cronológica e grupo de comparação, com 1.856 crianças da Villa Maria, Córdoba, Argentina. A estratégia foi implementada nos serviços públicos da cidade e consistiu em elaborar agendas de vacinação semanalmente, fazer monitoramento, contatar e desenvolver uma pesquisa ativa nos casos de não concorrência. Para avaliar o resultado foi utilizada a porcentagem de vacinados adequadamente com a terceira dose de quíntupla. Foram construídas séries cronológicas para cada grupo, antes e depois, foram analisadas com um modelo lineal simples. Foi calculada a media das porcentagens e seus intervalos de confiança usando bootstrap e foram comparados com o método de permutações. No grupo de intervenção, a média de porcentagem de vacinação oportuna aumentou significativamente 2,6 vezes, chegando a 61,7% (56,2; 78,1).

Prevalencia de enfermedad pulmonar obstructiva crónica en 6 aglomerados urbanos de Argentina: el estudio EPOC. AR / Prevalence of COPD in 6 Urban Clusters in Argentina: The EPOC. AR Study

Introducción: La prevalencia de la enfermedad pulmonar obstructiva crónica (EPOC) en Argentina no había sido estudiada. Objetivos: Determinar la prevalencia de EPOC y rasgos clínicos relevantes en una muestra representativa. Material y métodos: Estudio de corte transversal en población ≥40 años en 6 aglomerados urbanos seleccionada aleatoriamente mediante muestreo por conglomerados. Se aplicó una encuesta estructurada y espirometrías pre y postbroncodilatador (PBD). Se definió EPOC en quienes presentaban un cociente FEV1/FVC PBD<0,7. Se estimó la prevalencia total y para cada aglomerado con intervalo de confianza del 95% (IC). Resultados: Se realizaron 4.599 encuestas y 3.999 espirometrías, de las cuales 3.469 fueron útiles (86,8%). La prevalencia de EPOC fue de 14,5% (IC: 13,4-15,7). La distribución de los casos compatibles con EPOC según FEV1 (GOLD-2017) fue: 1: 38% (IC: 34-43); 2: 52% (IC: 47-56); 3: 10% (IC: 7-13); y 4: 1% (IC: 0,-2) y de acuerdo al modelo combinado ABCD (GOLD 2017): A: 52% (IC: 47-56); B: 43% (IC: 39-48); C: 1% (IC: 0-2) y D: 4% (IC: 2-6). El subdiagnóstico fue del 77,4% (IC 73,7-81,1%) y el error diagnóstico de 60,7% (IC 55,1-66,3%). Encontramos asociación significativa de presencia de EPOC con edad (OR 3,77 en 50-59 años a 19,23 en >80 años), sexo masculino (OR: 1,62; IC: 1,31-2), tabaquismo (OR: 1,95; IC: 1,49-2,54), nivel socieconómico bajo (OR: 1,33; IC: 1,02-1,73) y antecedentes de tuberculosis (OR: 3,3; IC: 1,43-7,62). Conclusiones: Se estima que más de 2,3 millones de argentinos padecen EPOC con elevada tasa de subdiagnóstico y error diagnóstico

Introduction: The prevalence of chronic obstructive pulmonary disease (COPD) has not been studied in Argentina. Objectives: To determine the prevalence and relevant clinical characteristics of COPD in a representative sample. Material and methods: We performed a cross-sectional study in a population of adults aged ≥ 40 years randomly selected by cluster sampling in 6 urban locations. Subjects answered a structured survey and performed pre- and post-bronchodilator spirometry (PBD). COPD was defined as FEV1/FVC ratio < 0.7 predicted value. The total prevalence was estimated for each cluster with its 95% confidence interval (CI). Results: Of 4,599 surveys and 3,999 spirometries, 3,469 were considered of adequate quality (86.8%) for our study. The prevalence of COPD was 14.5% (CI: 13.4-15.7). The distribution of COPD cases according to FEV1 (GOLD 2017) was stage 1: 38% (CI: 34-43); stage 2: 52% (CI: 47-56); stage 3: 10% (CI: 7-13); and stage 4: 1% (CI: 0-2), and according to the refined ABCD (GOLD 2017) assessment: A: 52% (CI: 47-56); B: 43% (CI: 39-48); C: 1% (CI: 0-2); D: 4% (CI: 2-6). The rate of underdiagnosis was 77.4% (CI 73.7-81.1%) and diagnostic error 60.7% (CI 55.1-66.3%). A significant association was found between COPD and age (OR 3.77 in individuals 50-59 years of age and 19.23 in those > 80 years), male gender (OR 1.62; CI 1.31-2), smoking (OR 1.95; CI 1.49-2.54), low socioeconomic status (OR 1.33; CI 1.02-1.73), and previous tuberculosis (OR 3.3; CI 1.43-7.62). Conclusions: We estimate that more than 2.3 million Argentineans have COPD, with high rates of underdiagnosis and diagnostic error

Prevalencia y características clínicas del asma en adultos jóvenes en zonas urbanas de Argentina / Prevalence and Features of Asthma in Young Adults in Urban Areas of Argentina

Objetivo: Estimar la carga del asma en la población adulta joven en zonas urbanas de Argentina. Diseño: Se realizó una encuesta telefónica a nivel nacional en sujetos de 20 a 44 años en áreas urbanas de Argentina. Se utilizó el cuestionario de la European Community Respiratory Health Survey. El asma se definió como ataque en el último año o uso de medicamentos para el asma. Resultados: Mil quinientos veintiún sujetos fueron encuestados (62,4% mujeres, edad media 33 años). Noventa y uno fueron clasificados como asmáticos (5,9%, IC 95% 4,7-7,1). La prevalencia ajustada por edad, sexo y nivel educativo fue de 6,4% (IC 95% 5,1-7,7). El porcentaje de sibilancia fue de un 13,9% (IC 95% 15,6-12,2) y el de diagnóstico médico de asma, de un 9,5% (IC 95% 8,0-11,0). Entre los diagnósticos (n = 154), el 71,3% realizó una espirometría y el 51,9% de los tratados (n = 77) utilizaba medicamentos diariamente y un 46,8% como rescate. De los que reportaron algún ataque en el último año (n = 60), un 55% tuvieron una visita a Urgencias y un 23,3% fueron hospitalizados. El asma se asoció con rinitis (OR 11,1; IC 95% 6,2-19,9) e historia familiar (OR 3,6; IC 95% 2,3-5,5). Conclusión: La prevalencia de asma en adultos jóvenes en Argentina es similar a la de Europa. Aunque los ataques y las admisiones fueron comunes, el uso regular de los medicamentos fue informado por la mitad de los tratados. Los resultados pueden ser útiles para otros países de América Latina (AU)

Objective: To investigate the burden of asthma in a young adult population in urban areas of Argentina. Design: A nationwide telephone survey in subjects aged 20-44 years was performed in urban areas in Argentina. The European Community Respiratory Health Survey questionnaire was used. Asthma was defined as an exacerbation in the last year or use of asthma medications. Results: In total, 1,521 subjects responded (62.4% females, mean age 33 years), of whom 91 were classified as asthmatics (5.9%, 95% CI 4.7-7.1). Prevalence adjusted for age, sex and education level was 6.4% (95% CI 5.1-7.7). Wheezing was reported by 13.9% (95% CI 15.6-12.2) and a diagnosis of asthma by 9.5% (95% CI 8.0-11.0). Among individuals with a diagnosis of asthma (n=154), 71.3% had undergone spirometry. Among those treated (n=77), 51.9% used medications daily and 46.8% as a rescue measure. Of those reporting an exacerbation in the last year (n=60), 55% had attended an emergency department and 23% were admitted. Asthma was associated with rhinitis (OR 11.1, 95% CI 6.2-19.9) and family history (OR 3.6, 95% CI 2.3-5.5). Conclusion: Asthma prevalence in young adults in Argentina is similar to Europe. Although attacks and admissions were common, regular use of medications was reported by half of those treated. These results may be useful for other Latin American countries (AU)

Prevalence of COPD in 6 Urban Clusters in Argentina: The EPOC.AR Study. / Prevalencia de enfermedad pulmonar obstructiva crónica en 6 aglomerados urbanos de Argentina: el estudio EPOC.AR.

INTRODUCTION: The prevalence of chronic obstructive pulmonary disease (COPD) has not been studied in Argentina. OBJECTIVES: To determine the prevalence and relevant clinical characteristics of COPD in a representative sample. MATERIAL AND METHODS: We performed a cross-sectional study in a population of adults aged ≥ 40 years randomly selected by cluster sampling in 6 urban locations. Subjects answered a structured survey and performed pre- and post-bronchodilator spirometry (PBD). COPD was defined as FEV1/FVC ratio < 0.7 predicted value. The total prevalence was estimated for each cluster with its 95% confidence interval (CI). RESULTS: Of 4,599 surveys and 3,999 spirometries, 3,469 were considered of adequate quality (86.8%) for our study. The prevalence of COPD was 14.5% (CI: 13.4-15.7). The distribution of COPD cases according to FEV1 (GOLD 2017) was stage 1: 38% (CI: 34-43); stage 2: 52% (CI: 47-56); stage 3: 10% (CI: 7-13); and stage 4: 1% (CI: 0-2), and according to the refined ABCD (GOLD 2017) assessment: A: 52% (CI: 47-56); B: 43% (CI: 39-48); C: 1% (CI: 0-2); D: 4% (CI: 2-6). The rate of underdiagnosis was 77.4% (CI 73.7-81.1%) and diagnostic error 60.7% (CI 55.1-66.3%). A significant association was found between COPD and age (OR 3.77 in individuals 50-59 years of age and 19.23 in those > 80 years), male gender (OR 1.62; CI 1.31-2), smoking (OR 1.95; CI 1.49-2.54), low socioeconomic status (OR 1.33; CI 1.02-1.73), and previous tuberculosis (OR 3.3; CI 1.43-7.62). CONCLUSIONS: We estimate that more than 2.3 million Argentineans have COPD, with high rates of underdiagnosis and diagnostic error.
