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.

Influência do tempo de internação hospitalar sobre a variabilidade da frequência cardíaca pediátrica por meio de método linear / Influence of hospital stay on the variability of pediatric heart rate by linear method / Influencia de la estancia hospitalaria en la variabilidad de la frecuencia cardiaca pediátrica por método lineal

INTRODUÇÃO: A imobilização prolongada acarreta prejuízos sistêmicos que repercute diretamente em maiores agravos aos pacientes, dentre eles se encontra a redução da VFC, indicativo de maior morbimortalidade clínica. OBJETIVO: Analisar se o tempo de internação hospitalar influencia a modulação autonômica da frequência cardíaca em pacientes pediátricos. METODOLOGIA: Estudo longitudinal, quantitativo e prospectivo, realizado em uma enfermaria pediátrica. A amostra foi de pacientes entre 4 a 11 anos, ambos gêneros, internados dentro das primeiras 48 horas. A coleta iniciou após a assinatura do TCLE pelo responsável, seguida do colhimento dos dados pessoais e clínicos dos pacientes seguida da coleta da VFC, repetida no último dia de internação. A captação da VFC foi realizada pelo monitor Polar RS800CX. Os dados foram transferidos e passados por uma análise matemática no programa Kubios HRV2.2. Por fim, os dados foram tabulados e analisados pelo Microsoft Excel 2013 e software BioEstat® 5.3 respectivamente. RESULTADOS: Os valores lineares no domínio do tempo obtiveram média pré (IRR=644,7 com P=0,42; RMSSD= 46,1 com P=0,017 e SDNN=43,5 com P=0,017) e pós (IRR=656,3; RMSSD=34,8; SDNN=35,38) e no domínio da frequência média pré (LF=41,9 com P=0,013; HF=58,0 com P=0,013; LF/HF=1,03 com P=0,04) e pós (LF=52,2; HF=47,7; LF/HF=3,56). A correlação de Pearson na análise tanto de RMSSD pós x tempo de internação, quanto SDNN pós x tempo de internação demonstraram R=0,55 e R=0,59 respectivamente. CONCLUSÃO: Foi observado que o tempo de internação exerce influência negativa sobre a modulação autonômica da frequência cardíaca em pacientes pediátricos.

INTRODUCTION: Prolonged immobilization causes systemic damage that has a direct impact on greater harm to patients, among which is the reduction in HRV, indicative of greater clinical morbidity and mortality. OBJECTIVE: To analyze whether the length of hospital stay influences the autonomic modulation of heart rate in pediatric patients. METHODOLOGY: Longitudinal, quantitative and prospective study, carried out in a pediatric ward. The sample consisted of patients between 4 and 11 years old, both genders, hospitalized within the first 48 hours. The collection began after the signature of the TCLE by the guardian, followed by the collection of the patients' personal and clinical data, followed by the HRV collection, repeated on the last day of hospitalization. HRV capture was performed by the Polar RS800CX monitor. The data were transferred and passed through a mathematical analysis in the Kubios HRV2.2 program. Finally, data were tabulated and analyzed using Microsoft Excel 2013 and BioEstat® 5.3 software, respectively. RESULTS: Linear values in the time domain obtained mean pre (IRR=644.7 with P=0.42; RMSSD=46.1 with P=0.017 and SDNN=43.5 with P=0.017) and post (IRR=656.3; RMSSD=34.8; SDNN=35.38) and in the pre mean frequency domain (LF=41.9 with P=0.013; HF=58.0 with P=0.013; LF/HF=1,03 with P=0.04) and powders (LF=52.2; HF=47.7; LF/HF=3.56). Pearson's correlation in the analysis of both the RMSSD post x length of stay and the SDNN post x length of stay showed R=0.55 and R=0.59 respectively. CONCLUSION: It was observed that the length of stay has a negative influence on the autonomic modulation of heart rate in pediatric patients.

CONCLUSIÓN: Se observó que la duración de la estancia influye negativamente en la modulación autonómica de la frecuencia cardíaca en pacientes pediátricos.

Efecto de la técnica de la tos durante la inyección subcutánea de heparina sobre la severidad del dolor y la satisfacción individual / Effect of the coughing technique during subcutaneous heparin injection on pain severity and individual satisfaction / Efeito da técnica de tosse durante injeção subcutânea de heparina na intensidade da dor e satisfação individual

Objetivo: examinar el efecto de la técnica de tos de mediana intensidad durante la inyección subcutánea de heparina de bajo peso molecular sobre la severidad del dolor y la satisfacción individual en pacientes de cirugía general. Método: estudio prospectivo, cuasi experimental, que incluyó a 100 pacientes a los que se les prescribió una inyección subcutánea de heparina de bajo peso molecular una vez cada 24 horas. Cada paciente recibió dos inyecciones por el mismo investigador utilizando técnica de inyección estándar con técnica de tos de intensidad media y solo técnica de inyección estándar. Resultados: hubo una diferencia estadísticamente significativa entre las puntuaciones medias de los pacientes sobre la intensidad del dolor y los niveles de satisfacción después de las inyecciones administradas por las dos técnicas (p= 0,000). Además, se encontró que el género afectó la severidad del dolor relacionado con la inyección, pero no afectó el nivel de satisfacción individual. Conclusión: se encontró que la técnica de tos de intensidad media reduce la severidad del dolor y aumenta la satisfacción del paciente de cirugía general que reciben inyecciones subcutáneas de heparina de bajo peso molecular. Registro del ensayo: NCT05681338.

Objective: to examine the effect of the medium intensity coughing technique during subcutaneous low molecular weight heparin injection on pain severity and individual satisfaction in general surgery patients. Method: the prospective, quasi-experimental study included 100 patients who had been prescribed a subcutaneous low molecular weight heparin injection once in 24 hours. Each patient received two injections by the same researcher, one using the standard injection technique with medium intensity coughing technique and the other only the standard injection technique. Results: there was a statistically significant difference between patients' mean scores on pain severity and satisfaction levels after injections administered by the two techniques (p= 0.000). Also, it was found that gender affected pain severity relating to the injection but did not affect the level of individual satisfaction. Conclusion: the medium intensity coughing technique was found to reduce pain severity and increase patient satisfaction in general surgery patients receiving subcutaneous low molecular weight heparin injections. Trial registration: NCT05681338.

Objetivo: examinar o efeito da técnica de tosse de média intensidade durante injeção subcutânea de heparina de baixo peso molecular na intensidade da dor e satisfação individual em pacientes submetidos à cirurgia geral. Método: estudo prospetivo, quasi experimental que incluiu 100 pacientes que haviam recebido uma injeção subcutânea de heparina de baixo peso molecular em 24 horas. Cada paciente recebeu duas injeções pelo mesmo pesquisador usando a técnica de injeção padrão com técnica de tosse de média intensidade e apenas técnica de injeção padrão. Resultados: houve diferença estatisticamente significativa entre as pontuações médias dos pacientes quanto à gravidade da dor e níveis de satisfação após as injeções administradas pelas duas técnicas (p = 0,000). Além disso, verificou-se que o sexo do paciente afetou a intensidade da dor relacionada à injeção, mas não afetou o nível de satisfação individual. Conclusão: a técnica de tosse de média intensidade reduz a intensidade da dor e aumenta a satisfação de pacientes submetidos à cirurgia geral recebendo injeções subcutâneas de heparina de baixo peso molecular. Registro do ensaio clínico: NCT05681338.

Potenciales evocados auditivos de tronco en neonatos nacidos a gran altitud / Brainstem auditory evoked potentials in newborn infants born in a high-altitude area

Introducción. Una forma no invasiva y segura de evaluar los parámetros neurofisiológicos en recién nacidos es la evaluación de los potenciales evocados auditivos del tronco encefálico (PEAT). Objetivo. Evaluar las latencias e intervalos de ondas de los PEAT en neonatos sanos nacidos a gran altitud (Cusco, 3399 msnm). Población y métodos. Estudio transversal y prospectivo. Se incluyeron neonatos menores a 14 días de vida, dados de alta a menos de 7 días de nacidos, evaluados para determinar los valores de los PEAT a intensidades sonoras de 70 dB, 80 dB y 90 dB. Se incluyeron las variables edad gestacional, peso al nacer, tipo de parto. Se calcularon las diferencias de las medianas de las latencias e intervalos de las ondas según edad gestacional y peso al nacer. Resultados. Se evaluaron 96 neonatos (17 pretérminos). Las medianas de las latencias de las ondas I a V a 90 dB fueron las siguientes: onda I 1,56 ms; onda II 2,74 ms; onda III 4,37 ms; onda IV 5,62 ms, onda V 6,63 ms. La latencia de la onda I para 80 dB fue de 1,71 ms y para 70 dB de 1,88 ms. Los intervalos para las ondas (I-III), (III-V) y (I-V) fueron de 2,8 ms, 2,2 ms y 5,0 ms respectivamente, sin diferencias entre intensidades (p >0,05). La prematuridad y el bajo peso estuvieron asociados a latencias de la onda I más prolongadas (p <0,05). Conclusiones. Se presentan valores ajustados de latencias e intervalos de los PEAT en neonatos nacidos a gran altitud. Se identificó que, a distintas intensidades sonoras, se ven diferencias en las latencias de las ondas, pero no en los intervalos entre ondas.

Introduction. A non-invasive and safe way to assess neurophysiological parameters in newborn infants is the evaluation of brainstem auditory evoked potentials (BAEPs). Objective. To assess the latencies and wave intervals of BAEPs in healthy newborn infants born in a high-altitude area (Cusco, 3399 MASL). Population and methods. Cross-sectional and prospective study. Newborn infants younger than 14 days of age, discharged less than 7 days after birth, were assessed to determine BAEP values at intensities of 70 dB, 80 dB, and 90 dB. The study variables were gestational age, birth weight, and type of delivery. The median differences in wave latencies and intervals were estimated according to gestational age and birth weight. Results. A total of 96 newborn infants (17 preterm infants) were assessed. The median latencies of waves I­V at 90 dB were for wave I: 1.56 ms, wave II: 2,74 ms, wave III: 4.37 ms, wave IV: 5.62 ms, and wave V: 6.63 ms. The latency of wave I for 80 dB was 1.71 ms and for 70 dB, 1.88 ms. Wave intervals (I­III, III­V, I­V) were 2.8 ms, 2.2 ms, and 5.0 ms, respectively, without differences among intensities (p > 0.05). Prematurity and low birth weight were associated with a longer wave I latency (p < 0.05). Conclusions. Here we describe adjusted BAEP latency and interval values for newborn infants born at high altitude. At different sound intensities, we identified differences in wave latencies, but not in interwave intervals.

Estudio comparativo entre un test de antígeno y la prueba de la reacción en cadena de la polimerasa en tiempo real (RT-PCR) para el diagnóstico de infección por COVID-19 en pediatría / Comparative study between an antigen test and the reverse transcription-polymerase chain reaction (RT-PCR) test for the diagnosis of COVID-19 in pediatrics

Introducción. La pandemia por COVID-19 ha puesto de manifiesto la necesidad de pruebas diagnósticas rápidas. La prueba de referencia es la reacción en cadena de la polimerasa en tiempo real (RT-PCR). Requiere un equipo y personal capacitado, y su resultado puede llevar un tiempo de espera prolongado. El sistema BD Veritor® es el método rápido cromatográfico utilizado para la detección del antígeno del coronavirus de tipo 2 del síndrome respiratorio agudo grave, en individuos sintomáticos. El objetivo primario del siguiente trabajo es evaluar sensibilidad y especificidad del test de antígeno (TA) comparadas con la RT-PCR en población pediátrica. Población y métodos. Estudio prospectivo, de prueba diagnóstica. Se incluyó a todo menor de 17 años en los primeros 5 días de inicio de síntomas, que consultó desde julio de 2021 hasta febrero de 2022. Se calculó un mínimo de 300 muestras para lograr una precisión de ± 8,76 % y de ± 3,68 % para sensibilidad y especificidad respectivamente. Se analizaron en paralelo las muestras por ambas metodologías. Resultados. De 316 muestras pareadas, 33 fueron positivas por ambos métodos; 6 fueron positivas solo por RT-PCR. La especificidad del TA fue del 100 %; la sensibilidad, del 84,6 %, con un valor predictivo positivo y negativo del 100 % y del 98 % respectivamente. Conclusiones. El TA demostró ser útil en el diagnóstico de pacientes pediátricos con COVID-19 en los primeros 5 días de inicio de síntomas, aunque aquellos con TA negativo y alta sospecha clínica deberían confirmar su resultado con la RT-PCR.

Introduction. The COVID-19 pandemic has brought to light the need for rapid diagnostic tests. The gold standard test is reverse transcription-polymerase chain reaction (RT-PCR). RT-PCR requires equipment and trained personnel, and results may take a long waiting time. The BD Veritor® System is a rapid chromatographic method used for the detection of severe acute respiratory syndrome coronavirus 2 antigen in symptomatic individuals. The primary objective of this study is to assess the sensitivity and specificity of the antigen test (AT) compared to the RT-PCR in the pediatric population. Population and methods. Prospective study with a diagnostic test. All children younger than 17 years in the first 5 days of symptom onset, who consulted between July 2021 and February 2022, were included. A minimum of 300 specimens was estimated to achieve an accuracy of ±8.76% and ±3.68% for sensitivity and specificity, respectively. Specimens were analyzed in parallel using both methodologies. Results. Of 316 paired samples, 33 were positive by both methods; 6 were positive only by RT-PCR. The specificity of the AT was 100%; sensitivity was 84.6%, with a positive and negative predictive value of 100% and 98%, respectively. Conclusions. The AT proved to be useful in the diagnosis of pediatric patients with COVID-19 in the first 5 days of symptom onset, although those with a negative AT and high clinical suspicion should confirm their result with a RT-PCR.

Educación alimentaria en pacientes en dialisis / Nutritional education in dialysis patients

La enfermedad renal crónica terminal aumenta el riesgo cardiovascular y puede ocasionar defectos en la mineralización ósea. Para prevenir esto, se debe mantener el fósforo plasmático normal, que depende de la diálisis, los quelantes y la ingesta de fósforo, principalmente de origen inorgánico, incorporado mediante aditivos alimentarios. Las intervenciones nutricionales son pilares en el tratamiento de estos pacientes. El objetivo es facilitar estrategias alimentarias a un grupo de pacientes pediátricos en diálisis, mediante educación alimentaria nutricional, para aumentar el consumo de alimentos naturales, disminuyendo la ingesta de fósforo inorgánico especialmente de los productos cárnicos procesados. Materiales y métodos: se estudió una población pediátrica en diálisis. Se preparó un programa educativo con atención personalizada, instrucción alimentaria y seguimiento mensual, seguido de un taller. Resultados: n: 17 pacientes, edad decimal media de 12,3, 53% sexo masculino, 88% en hemodiálisis. Previo a la intervención el 64,7% consumía productos cárnicos procesados. Luego del taller el 58,8% disminuyó su consumo, el 41,2% aumentó la ingesta de preparaciones caseras, el 53% incorporó nuevos condimentos, de los cuales el 89% presentó al incorporarlos, mejor aceptación a las preparaciones. Conclusiones: la hiperfosfatemia está presente en alrededor del 50% de los pacientes en diálisis asociándose a un incremento entre 20% al 40% del riesgo de mortalidad. La presencia de fósforo oculto en los alimentos y la falta de adherencia hacen prioritario trabajar en programas educativos que favorezcan el aprendizaje colaborativo, centralizados en prácticas culinarias, para brindar herramientas que faciliten una alimentación natural, disminuyendo el consumo de ultraprocesados (AU)

Chronic end-stage renal disease increases the risk of cardiovascular disease and may lead to defects in bone mineralization. In order to prevent these risks, normal plasma phosphorus levels should be maintained. Achieving this goal depends on dialysis, chelators, and phosphorus intake, mainly of inorganic origin, incorporated through food supplements. Nutritional interventions are crucial in the treatment of these patients. The objective is to facilitate nutritional strategies to a group of pediatric dialysis patients, through food education, to increase the consumption of natural foods, decreasing the intake of inorganic phosphorus, especially from processed meat products. Materials and methods: a pediatric population undergoing dialysis was studied. An educational program was prepared with personalized care, nutritional instruction, and monthly follow-up visits, followed by a workshop. Results: n: 17 patients, mean age 12.3 years, 53% male, 88% on hemodialysis. Prior to the intervention, 64.7% consumed processed meat products. After the workshop, 58.8% decreased their consumption, 41.2% increased the intake of homemade food, 53% incorporated new seasonings, of whom 89% reported better acceptance of the preparations when they were incorporated. Conclusions: hyperphosphatemia is observed in around 50% of patients undergoing dialysis and is associated with a 20% to 40% increased risk of mortality. The presence of hidden phosphorus in food and the lack of adherence point to the need for the development of educational programs that promote collaborative learning, focusing on food-preparation practices. These programs should provide tools that facilitate a natural diet, reducing the consumption of ultra-processed food (AU)

Salud y discapacidad en niñas y niños argentinos con cardiopatías congénitas complejas operadas. Resultados a los dos años de vida / Health and disability in Argentine children with complex congenital heart disease undergoing surgery. Outcomes at 2 years of life

Introducción. Las cardiopatías congénitas complejas son las malformaciones más frecuentes con una importante carga de morbimortalidad. Se busca conocer el estado de salud y discapacidad de niños operados en un hospital de tercer nivel. Población y métodos. Fueron evaluados en las áreas de crecimiento, neurodesarrollo y discapacidad 84 pacientes entre 21 y 39 meses de edad operados con circulación extracorpórea durante el primer año de vida. Resultados. La mayoría de los niños crece por debajo del percentil 50 en los tres parámetros, con mayor compromiso en aquellos con síndrome genético asociado. La frecuencia de discapacidad fue del 55 %. En el grupo con CC aislada, la gravedad de la cardiopatía y el examen neurológico patológico al alta se asociaron con discapacidad (p = 0,047 y p = 0,03). Contar solo con cobertura de salud pública se asocia a un menor acceso a intervenciones oportunas (p = 0,02). Conclusiones. Cerca de la mitad de los pacientes evoluciona con discapacidad moderada-grave. Es competencia del equipo de salud conocer las morbilidades más allá del aspecto cardiovascular y los factores de riesgo. Las barreras en el acceso a las intervenciones adecuadas advierten a los profesionales sobre la relevancia de buscar estrategias para vencerlas y lograr el máximo potencial de desarrollo de los pacientes.

Introduction. Complex congenital heart defects are the most frequent malformations and entail a significant burden of disease. The objective of this study was to determine the health status and disability of children who underwent surgery at a tertiary care hospital. Population and methods. A total of 84 patients aged 21 to 39 months who had a surgery with extracorporeal circulation during their first year of life were assessed in terms of growth, neurodevelopment, and disability. Results. In most children, growth was below the 50th percentile in all 3 parameters, and greater involvement was observed in those with an associated genetic disorder. The frequency of disability was 55%. In the group with isolated congenital heart disease, the severity of disease and a pathological neurological examination at discharge were associated with disability (p = 0.047 and p = 0.03). Having only public health coverage was associated with less access to timely interventions (p = 0.02). Conclusions. Nearly half of the patients develop moderate-severe disability. Being aware of morbidities beyond the cardiovascular aspect and risk factors is part of the health care team's scope. Barriers in access to appropriate interventions caution health care providers of the relevance of seeking strategies to overcome them and achieve the maximum development potential of patients.

Traslado no programado de pacientes pediátricos desde una sala de internación general a una unidad de cuidados intensivos / Unplanned transfer of pediatric patients from the general ward to the intensive care unit

Introducción. Durante la internación, los pacientes pueden presentar un deterioro clínico significativo y requerir el ingreso no programado a la unidad de cuidados intensivos pediátricos (UCIP). Esto puede conllevar un aumento de la morbilidad y la mortalidad. Frecuentemente, estos eventos están precedidos por una fase de deterioro que podría pasar desapercibida. Objetivo. Determinar la frecuencia, analizar las causas, describir las características clínicas y los resultados de los traslados no programados en pacientes pediátricos hospitalizados, desde el área de internación general pediátrica (IGP) a la UCIP, y analizar las diferencias entre traslados urgentes y emergentes. Población y métodos. Estudio descriptivo prospectivo; se analizaron todos los traslados no programados desde IGP a la UCIP ocurridos entre el 1 de enero de 2014 y el 31 de diciembre 2019. Resultados. Se constataron 212 traslados no programados (21 traslados cada 1000 ingresos). El 76 % de los pacientes trasladados presentaban una comorbilidad asociada ­la más frecuente fue la patología oncológica (36 %)­ y llevaban más de 24 horas internados en IGP. Las causas más frecuentes de traslado fueron dificultad respiratoria (43 %), sepsis (20 %) y complicaciones neurológicas/neuroquirúrgicas (20 %). La tasa de mortalidad global fue del 8,96 % (19 pacientes). Conclusiones. El análisis de los traslados no programados es un elemento esencial en la evaluación de la calidad de atención y seguridad del paciente de un área, y debe constituir un indicador integrado al tablero de control. La interpretación de los traslados no programados como un evento prevenible constituye un cambio de paradigma clave.

Introduction. During hospitalization, patients may develop significant clinical deterioration and require unplanned admission to the pediatric intensive care unit (PICU). This may result in increased morbidity and mortality. These events are often preceded by a deterioration phase that may go unnoticed. Objective. To determine the frequency, analyze the causes, and describe the clinical characteristics and outcomes of unplanned transfers of hospitalized pediatric patients from the general pediatric ward (GPW) to the PICU, and analyze the differences between urgent and emergent transfers. Population and methods. Prospective, descriptive study; all unplanned transfers from the GPW to the PICU occurring between January 1st, 2014 and December 31st, 2019 were analyzed. Results. There were 212 unplanned transfers (21 transfers per 1000 admissions). An associated comorbidity was present in 76% of transferred patients ­being cancer the most frequent one (36%)­ and they had been hospitalized for more than 24 hours in the GPW. The most frequent causes of transfer were respiratory distress (43%), sepsis (20%), and neurological/neurosurgical complications (20%). The overall mortality rate was 8.96% (19 patients). Conclusions. The analysis of unplanned transfers is a critical component in the assessment of the quality of care and patient safety of an area, and should be an indicator integrated into the control panel. The interpretation of unplanned transfers as a preventable event is a key paradigm shift.

Application of Sphenoid Sinus Morphological Characteristics in Sex Estimation Based on Magnetic Resonance Imaging Images / Aplicación de las Características Morfológicas del Seno Esfenoidal en la Estimación del Sexo Basada en Imágenes de Resonancia Magnética

SUMMARY: Sex determination of unknown persons plays an important role in forensic science. As most bones used for sex determination are recovered in incomplete state, it is often necessary to use bones that are recovered intact e.g., the sphenoid sinus. This study aimed to evaluate the diagnostic value of sphenoid sinuses dimensions for sex determination using Magnetic Resonance Imaging (MRI) images in Chinese adults. MRI images of 79 sphenoid sinuses (from 44 men and 35 women) were retrospectively selected. The height, anterior-posterior diameter, area, and perimeter were measured in the midsagittal view of the sphenoid sinuses. All data were subjected to descriptive and discriminative functional analysis with unpaired t-test and canonical discriminant. Comparison between male and female groups showed significant statistical differences regarding the height, anterior-posterior diameter, area, and perimeter of sphenoid sinuses. The predictive accuracy rate of the sphenoid sinus to identify sex was 63.6 % in males and 62.9 % in females with an overall accuracy of 63.3 %. This study proposed the importance of sexual dimorphism of sphenoid sinus dimensions, especially if other methods are not available. It suggested using MRI in forensics science thus obviating the complete dependence on the usage of conventional computed tomography (CT) and facilitating the study of forensic anatomy at the level of soft tissue.

La determinación del sexo de personas desconocidas juega un papel importante en la ciencia forense. Como la mayoría de los huesos utilizados para la determinación del sexo se recuperan en un estado incompleto, a menudo es necesario utilizar huesos recuperados intactos, por ejemplo, el seno esfenoidal. Este estudio tuvo como objetivo evaluar el valor diagnóstico de las dimensiones de los senos esfenoidales para la determinación del sexo utilizando imágenes de resonancia magnética en individuos adultos chinos. Se seleccionaron retrospectivamente imágenes de resonancia magnética de 79 senos esfenoidales (de 44 hombres y 35 mujeres). La altura, el diámetro anteroposterior, el área y el perímetro de los senos esfenoidales, se midieron en vista mediana sagital. Todos los datos se sometieron a análisis funcional descriptivo y discriminativo con prueba t no pareada y discriminante canónico. La comparación entre los grupos de hombres y mujeres mostró diferencias estadísticas significativas en cuanto a la altura, el diámetro anteroposterior, el área y el perímetro de los senos esfenoidales. La tasa de precisión predictiva del seno esfenoidal para identificar el sexo fue del 63,6 % en hombres y del 62,9 % en mujeres, con una precisión general del 63,3 %. Este estudio propuso la importancia del dimorfismo sexual de las dimensiones del seno esfenoidal, especialmente si no se dispone de otros métodos. Se sugiere utilizar la resonancia magnética en la ciencia forense, obviando así la dependencia total del uso de la tomografía computarizada convencional y facilitando con esto el estudio de la anatomía forense a nivel de los tejidos blandos.

Multitasking in postanesthesia care unit following nurse interruptions, an analysis of the causes and consequences using classification tree: an observational prospective study

Abstract Background: Postanesthesia Care Unit (PACU) is an environment associated with an important workload which is susceptible to lead to task interruption (TI), leading to task-switching or concurrent multitasking. The objective of the study was to determine the predictors of the reaction of the nurses facing TI and assess those who lead to an alteration of the initial task. Methods: We conducted a prospective observational study into the PACU of a university hospital during February 2017. Among 18 nurses, a selected one was observed each day, documenting for each TI the reaction of the nurse (task switching or concurrent multitasking), and the characteristics associated with the TI. We performed classification tree analyses using C5.0 algorithm in order to select the main predictors of the type of multitasking performed and the alteration of the initial task. Results: We observed 1119 TI during 132 hours (8.5 TI/hour). The main reaction was concurrent multitasking (805 TI, 72%). The short duration of the task interruption (one minute or less) was the most important predictor leading to concurrent multitasking. Other predictors of response to TI were the identity of the task interrupter and the number of nurses present. Regarding the consequences of the task switching, long interruption (more than five minutes) was the most important predictor of the alteration of the initial task. Conclusions: By analysing the predictors of the type of multitasking in front of TI, we propose a novel approach to understanding TI, offering new perspective for prevention strategies.

Política de medicamentos de alto costo en un hospital público pediátrico: Análisis de utilización y costos / High-cost medication policy at a public pediatric hospital: utilization and cost analysis

Objetivos. Analizar el circuito de utilización de los medicamentos de alto costo (MAC) y los resultados clínicos obtenidos en un hospital de pediatría público de alta complejidad de Argentina y presentar una estrategia de selección replicable para otras instituciones de similares características de la región. Métodos: Estudio prospectivo, descriptivo, aleatorizado, conducido en el Hospital de Pediatría Juan P. Garrahan de la Ciudad Autónoma de Buenos Aires en el período entre el 1 de setiembre de 2018 y el 31 de marzo de 2019. Se evaluaron dos unidades de estudio, la unidad paciente y la unidad MAC. Resultados: Los MAC consumen 7.921.200 dólares estadounidenses (USD) anuales y representan el 41% del costo de los medicamentos del hospital de alta complejidad. El 50% del costo de los MAC estuvo representado por la gammaglobulina (medicamento utilizado en diferentes enfermedades). Los pacientes proceden de toda la Argentina y otros países y un 44% tiene cobertura de salud. Los diagnósticos para los que se prescribieron MAC con mayor frecuencia fueron los relacionados con patología oncológica (leucemia linfoide aguda, leucemia mieloblástica aguda). El 54% de los pacientes presentó mejoría atribuible directamente a la administración de los MAC, 39% no presentó cambios y el 7% empeoró. Conclusiones: La efectividad en los resultados clínicos y el análisis de los circuitos de aprobación indican que, además de la aprobación por las entidades nacional e internacionales, la evaluación responsable por parte de las instituciones efectoras, mediante la discusión interdisciplinaria basada en la mejor evidencia, contribuye a optimizar la utilización de los MAC y la seguridad de los pacientes (AU)

Objectives. To analyze the utilization circuit of high-cost medications (HCM) and the clinical results obtained in a tertiarycare public pediatric hospital in Argentina and to present a selection strategy that may be disseminated to other institutions of similar characteristics in the region. Methods: A prospective, descriptive, randomized study was conducted at Hospital de Pediatría Juan P. Garrahan in Buenos Aires between September 1, 2018 and March 31, 2019. Two study units were evaluated, the patient and the HCM. Results: HCMs account for 7,921,200 US dollars (USD) per year and represent 41% of the cost of drugs in this tertiary-care hospital. Gamma globulin (a drug used for different diseases) accounted for 50% of the cost of HCMs. Patients came from Argentina and other countries and 44% had a health insurance. Cancer (acute lymphoid leukemia, acute myeloblastic leukemia) was the diagnosis for which HCMs were most frequently prescribed. Fifty-four percent of patients showed improvement directly attributable to the administration of HCMs, 39% showed no change, and 7% worsened. Conclusions: The effectiveness in clinical outcomes and the analysis of approval circuits show that, in addition to approval by national and international entities, responsible evaluation by the effector institutions through interdisciplinary discussion based on the best evidence contributes to optimizing the use of HCMs and patient safety (AU)

Effects of a new-generation hybrid contact lens on visual performance and vision-related quality of life in patients with keratoconus / Os efeitos de uma lente de contato híbrida de nova geração no desempenho visual e na qualidade de vida relacionada à visão em pacientes com ceratocone

ABSTRACT Purpose: The aim of this study was to evaluate the efficacy of a new-generation hybrid contact lens for improving visual outcomes and vision-related quality-of-life performance in patients with keratoconus who had intolerance or treatment failure of conventional correction methods such as the use of soft silicone-hydrogel or rigid gas-permeable contact lenses. Methods: Twenty-eight patients with keratoconus (42 eyes) were enrolled in this prospective cross-sectional study. Airflex (Swisslens) lenses were fitted in the patients' eyes in accordance with the manufacturer's instruction. Ophthalmologic examinations, including manifest refraction, best-corrected distance visual acuity, slit-lamp biomicroscopy, and National Eye Institute Visual Function Questionnaire 25 (NEI-VFQ-25) assessment, were performed at baseline and the 6-month visit. Results: An adequate fit was achieved in 39 eyes (92.9%) of 26 patients. Six eyes of 3 patients were excluded from the study owing to discontinuation of lens wearing. The mean age of the successful wearers was 20.3 ± 4.9 years. The mean best-corrected distance visual acuity was statistically significantly improved from 0.62 ± 0.30 to 0.11 ± 0.06 logMAR with the Airflex hybrid contact lenses (p<0.001). The mean overall composite NEI-VFQ-25 score statistically significantly increased with the Airflex hybrid contact lenses at the 6-month visit as compared with that at baseline (from 77.1 ± 16.3 to 90.9 ± 7.3, p=0.036). Statistically significantly better scores were obtained with the Airflex hybrid contact lenses in all the NEI-VFQ-25 subscale items (all p<0.05). No significant adverse effects were observed. Conclusions: New-generation hybrid contact lenses can be used as an effective alternative for correction of irregular astigmatism in patients with keratoconus who have intolerance or treatment failure of conventional methods. Significant improvement in vision-related quality-of-life in patients with keratoconus can be achieved with these lenses.

RESUMO Objetivo: Este estudo tem como objetivo avaliar a eficácia de lentes de contato híbridas de nova geração nos resultados visuais e na qualidade de vida relacionada à visão em pacientes com ceratocone com intolerância ou insucesso dos métodos de correção habituais, tais como lentes flexíveis de silicone-hidrogel ou rígidas permeáveis a gases. Métodos: Foram incluídos neste estudo transversal prospectivo 42 olhos de 28 pacientes com ceratocone. Uma lente Airflex (Swisslens) foi aplicada nos olhos de acordo com as instruções do fabricante. Um exame oftalmológico, incluindo refração manifesta, melhor acuidade visual corrigida para longe, biomicroscopia com lâmpada de fenda e a aplicação do National Eye Institute Visual Function Questionnaire-25 (NEI-VFQ-25), foi realizado no início do estudo e na visita de 6 meses. Resultados: Foi possível obter um ajuste adequado em 39 olhos (92,9%) de 26 pacientes. Foram excluídos do estudo 6 olhos de 3 pacientes devido à cessação do uso de lentes. A idade média dos usuários bem-sucedidos era de 20,3 ± 4,9 anos. A média da melhor acuidade visual corrigida para longe foi melhorada estatisticamente de 0,62 ± 0,30 para 0,11 ± 0,06 logMAR com as lentes de contato híbridas Airflex (p<0,001). A pontuação média geral composta no questionário NEI-VFQ-25 aumentou de forma estatisticamente significativa com a lente de contato híbrida Airflex na visita de 6 meses, em comparação com a pontuação inicial (de 77,1 ± 16,3 para 90,9 ± 7,3, p=0,036). As lentes de contato híbridas Airflex apresentaram pontuações melhores com significância estatística em todos os itens das sub-escalas do NEI-VFQ-25 (todos com p<0,05). Nenhum efeito adverso significativo foi observado. Conclusões: Lentes de contato híbridas de nova ge ração podem ser usadas como uma alternativa eficaz para a correção do astigmatismo irregular em pacientes com ceratocone com intolerância ou insucesso dos métodos habituais. Com essas lentes, pode-se alcançar uma melhora significativa na qualidade de vida relacionada à visão em pacientes com ceratocone.

A novel interlamellar oral mucosa graft surgery technique using fibrin glue for the treatment of trichiasis / Nova técnica cirúrgica de enxerto interlamelar de mucosa oral usando cola de fibrina para o tratamento de triquíase

ABSTRACT Purpose: The purpose of this study was to evaluate the long-term outcomes of patients with trichiasis treated with a modified interlamellar oral mucosa graft surgery technique using fibrin glue. Methods: A prospective study was conducted at the Oculoplastic Department of Ouro Verde Hospital Complex. Patients with recurrent trichiasis without entropion who did not respond to conventional therapy, underwent intermarginal lamellar splitting of the eyelid and oral mucous graft insertion with fibrin glue replacing sutures. They were then evaluated at 1-day, 1-week, 1-month, 6-month, and 4-year follow-ups. Graft adherence, symptom resolution, esthetic satisfaction, overall patient satisfaction, and trichiasis recurrence were assessed at 6-month and 4-year follow-ups. Results: Fifteen patients (a total of 19 eyes) were included, of whom 10 (66.7%) were female and 5 (33.3%) were male. The mean age was 75.4 ± 10.5 years (range, 54-98 years). Acquired trichiasis was the main cause. Of the patients with acquired trichiasis, 12 (86.7%) had chronic blepharitis, 2 (13.3%) had an undetermined cause, and one (6.7%) had trachomatous trichiasis. Most cases involved only one eyelid segment (89.4%) and =5 lashes (84.2%; minor trichiasis). No adverse reactions from the fibrin glue were reported and no sutures were required after graft placement. At 6 months, no graft failures occurred, 17 eyes of 13 patients (89.4%) showed good graft adherence, 2 eyes of 2 patients (10.5%) showed partial graft adherence, and 2 eyes of 1 patient (10.5%) had trichiasis recurrence. At 4-year follow-up, no graft failure occurred, 3 patients (3 eyes) were lost to follow-up, and 2 eyes of 2 patients (14.2%) had trichiasis recurrence. The 4-year cumulative success rate was 78.9%. Conclusions: The modified interlamellar surgery with fibrin glue showed a good long-term success rate. This technique reduces surgical time, facilitates smaller graft insertion, and therefore, should be considered for recalcitrant minor trichiasis without entropion.>

RESUMO Objetivo: O objetivo deste estudo foi avaliar os resultados a longo prazo da técnica cirúrgica modificada de enxerto interlamelar de mucosa oral usando cola de fibrina para o tratamento de triquíase. Métodos: Um estudo prospectivo foi realizado no Departamento de Óculo-plástica do Complexo Hospital Ouro Verde. Pacientes com triquíase recorrente sem entrópio, que não responderam à terapia convencional, foram submetidos à cirurgia com separação intermarginal das lamelas das pálpebras e inserção de enxerto de mucosa oral usando cola de fibrina, substituindo a sutura. Pacientes foram avaliados 1 dia, 7 dias, 1 mês, 6 meses e 4 anos após a cirurgia. A aderência do enxerto, resolução dos sintomas, satisfação estética, satisfação geral do paciente e recorrência de triquíase foram avaliados aos 6 meses e aos 4 anos. Resultados: Quinze pacientes (total de 19 olhos) foram incluídos, dos quais 10 (66.7%) eram do sexo feminino e 5 (33.3%) do sexo masculino. A média de idade foi 75.4 ± 10.5 anos (intervalo 54-98 anos). Triquíase adquirida foi a principal causa, da qual 12 pacientes apresentaram blefarite crônica (86.7%), 2 pacientes com causa indeterminada (13.3%) e 1 paciente com triquíase tracomatosa (6.7%). A maioria dos casos envolveu apenas um segmento da pálpebra (89.4%) e com =5 cílios (84.2%; triquíase menor). Nenhuma reação adversa foi reportada com o uso da cola de fibrina e nenhum caso necessitou de sutura após inserção do enxerto. Aos 6 meses, não houve nenhuma falha de enxerto, 17 olhos de 13 pacientes (89.4%) apresentaram boa aderência de enxerto, 2 olhos de 2 pacientes (10.5%) mostraram aderência parcial do enxerto e 2 olhos de 1 paciente (10.5%) apresentaram recorrência da triquíase. Aos 4 anos, não houve nenhuma falha de enxerto, 3 olhos de 3 pacientes tiveram perda de seguimento e 2 olhos de 2 pacientes (14.2%) apresentaram recorrência da triquíase. A taxa de sucesso acumulativa após 4 anos foi de 78.9%. Conclusão: A cirurgia modificada de enxerto interlamelar de mucosa oral usando cola de fibrina mostrou uma boa taxa de sucesso a longo prazo. Esta técnica reduz o tempo cirúrgico, facilita a inserção de enxertos menores e, portanto, deve ser considerada em triquíase menor sem entrópio resistente ao tratamento convencional.

Relationship between actinic keratosis and malignant skin lesions on the eyelid / Relação entre ceratose actínica e lesões cutâneas malignas na pálpebra

ABSTRACT Purpose: To evaluate the variables possibly related to actinic keratosis and malignant skin lesions on the eyelid. Methods: A prospective study of patients with suspected eyelid malignancy was conducted. The participants underwent a 2-mm punch biopsy at two opposite sites of the lesion for diagnosis, and the results were compared with those of the histopathological study of the surgical excised specimen. The patients with an actinic keratosis component were divided into two groups (actinic keratosis-associated malignancy and actinic keratosis alone), which were compared for the following variables: age, disease duration, largest diameter, tumor area, Fitzpatrick classification, sex, tumor site and margin involvement. A cluster analysis was also performed. Results: We analyzed 174 lesions, of which 50 had an actinic keratosis component. Actinic keratosis was associated with squamous cell carcinoma in 22% of the cases and to basal cell carcinoma in 38%, which shows that both neoplasms may have contiguous actinic keratosis. Statistical analysis revealed no significant difference among the variables. In a cluster analysis, four groups were identified with malignant lesions in the medial canthus with the largest mean diameter and area. All margin involvements on the lower eyelid were related to malignancy, which means that all cases with margin involvement had an almost 100% risk of malignancy. Conclusions: Larger actinic keratosis lesions in the medial canthus and lesions with margin involvement on the lower eyelid have a greater probability of malignant association.

RESUMO Objetivo: Avaliar as possíveis variáveis relacionadas à ceratose actínica e lesões malignas cutâneas nas pálpebras. Métodos: Estudo prospectivo de pacientes com lesões palpebrais suspeitas de malignidade. Os participantes foram submetidos à biopsia por trépano (punch) de 2-mm em dois pontos opostos da lesão como método diagnóstico e os resultados foram comparados com o estudo histopatológico da peça excisada cirurgicamente. Aqueles que apresentaram ceratose actínica como resultado foram divididos em dois grupos (ceratose actínica associada com malignidade e ceratose actínica isolada) e foram comparados de acordo com as variáveis: idade, tempo de doença, maior diâmetro, área do tumor, classificação de Fitzpatrick, gênero, localização e acometimento da margem palpebral. A análise de cluster também foi realizada. Resultados: Foram analisadas 174 lesões e 50 delas tinham ceratose actínica como componente do tumor. Ceratose actínica esteve associada ao Carcinoma Espinocelular em 22% dos casos e ao Carcinoma Basocelular em 38%, mostrando que ambos podem ter ceratose actínica adjacente. A análise estatística não encontrou diferença entre as variáveis. A análise de cluster identificou quatro grupos e mostrou que lesões malignas no canto medial tinham maiores diâmetro e área. Acometimento da margem na pálpebra inferior relacionou-se em 100% com malignidade, enquanto a ausência de acometimento da margem mostrou menor chance de malignidade. Conclusões: Lesões maiores de ceratose actínica no canto medial e lesões com acometimento da margem palpebral inferior têm maiores chances de associação com malignidade.

Comparación del desempeño de dos pruebas para la evaluación del neurodesarrollo infantil en un hospital pediátrico de la Ciudad Autónoma de Buenos Aires / Comparison of the performance of two tests for the assessment of child neurodevelopment in a children's hospital in the City of Buenos Aires

Introducción. La detección precoz de los trastornos del desarrollo permite aplicar acciones que mejoren su evolución y pronóstico. En nuestro país, la Prueba Nacional de Pesquisa (PRUNAPE) requiere de un profesional certificado. El Instrumento de Observación del Desarrollo Infantil (IODI) es una herramienta de vigilancia sistematizada del desarrollo que no requiere especialización para su aplicación. La utilización del IODI como herramienta de evaluación del neurodesarrollo sería de utilidad por su fácil aplicabilidad. Objetivo. Evaluar el desempeño del IODI como prueba de vigilancia de trastornos del desarrollo utilizando la PRUNAPE como patrón de oro. Población y métodos. Estudio prospectivo analítico de prueba diagnóstica. Se incluyeron de forma aleatoria pacientes de 1 mes a 4 años, cuyos padres dieron el consentimiento para participar. Se evaluó el desempeño del IODI usando la PRUNAPE como patrón de oro. Se estimaron los valores de clivaje de sensibilidad (S), especificidad (E), valores predictivos positivo y negativo (VPP y VPN), y las razones de verosimilitud positiva y negativa (RVP y RVN, respectivamente). Resultados. Se evaluaron 91 pacientes; 24 no pasaron la PRUNAPE, de los cuales 21 tampoco pasaron el IODI (sensibilidad: 87,5 %; especificidad: 79,1 %; valor predictivo positivo: 60,1 %; valor predictivo negativo: 94,6 %). Razón de verosimilitud positiva: 4,2; negativa: 0,2. Conclusión. El IODI mostró un desempeño aceptable como prueba de vigilancia de trastornos del desarrollo en comparación con la PRUNAPE.

Introduction. An early detection of developmental disorders allows to implement actions to improve their course and prognosis. In Argentina, the administration of the National Screening Test (Prueba Nacional de Pesquisa, PRUNAPE) requires a certified professional. The Child Development Observation Instrument (Instrumento de Observación del Desarrollo Infantil, IODI) is a systematized developmental surveillance tool that does not require specialization for its administration. The use of the IODI as a neurodevelopmental assessment tool would be useful because of its easy applicability. Objective. To assess the performance of the IODI as a surveillance test for developmental disorders using the PRUNAPE as a gold standard. Population and methods. Analytical, prospective study with a diagnostic test. Patients aged 1 month to 4 years, whose parents gave consent to participate, were included randomly. The IODI performance was assessed using the PRUNAPE as the gold standard. Sensitivity (S), specificity (Sp), positive and negative predictive values (PPV and NPV), and positive and negative likelihood ratios (PLR and NLR) were estimated. Results. Ninety-one patients were assessed; 24 failed the PRUNAPE, of these, 21 also failed the IODI (S: 87.5%, Sp: 79.1%, PPV: 60.1%, NPV: 94.6%). PLR: 4.2, NLR: 0.2. Conclusion. The IODI showed an acceptable performance as a developmental disorders surveillance test compared to the PRUNAPE.

Utilización de medicamentos off-label y unlicensed en una unidad de cuidados intensivos pediátricos de un hospital de alta complejidad español. Estudio descriptivo / Off-label and unlicensed drug use in a pediatric intensive care unit of a tertiary care Spanish hospital. A descriptive study

Introducción. En las unidades de cuidados intensivos pediátricos, se utiliza gran cantidad de medicamentos, muchos prescritos fuera de las condiciones establecidas en su ficha técnica (prescripciones off-label y unlicensed). El objetivo de este estudio fue describir el uso de medicamentos y estimar la prevalencia de fármacos off-label y unlicensed en una unidad de cuidados intensivos pediátricos de un hospital de tercer nivel español. Población y métodos. Estudio transversal, observacional, de una cohorte de niños ingresados en una unidad de cuidados intensivos pediátricos. El estudio se llevó a cabo en 2017. Se revisó cada fármaco prescrito, sus condiciones de uso y administración. Además, se analizaron las fichas técnicas de los fármacos implicados con la finalidad de identificar si el uso de los medicamentos se realizaba según sus condiciones de autorización, o bien se hacía fuera de prospecto (off-label) o como unlicensed. Resultados. La muestra fue de 97 pacientes. El 74,2 % (n = 72) de los pacientes recibieron algún fármaco off-label o unlicensed. El 23,8 % (n = 243) de las prescripciones fueron off-label y el 8,7 % (n = 89), unlicensed. El subanálisis realizado por grupos de edad mostró que el grupo de edad que recibió mayor número de prescripciones totales (n = 611) y el mayor porcentaje de fármacos prescritos en condiciones off-label y/o unlicensed (38,4 %) fue el de menores de 2 años. Conclusiones. La prescripción de fármacos off-label y/o unlicensed es una práctica habitual en la unidad de cuidados intensivos pediátricos. Este estudio permite documentar la complejidad de la terapéutica en niños.

Introduction. In pediatric intensive care units, a large number of drugs are used, many of which are prescribed for condition beyond those established in their summary of product characteristics (off-label and unlicensed drug prescriptions). The objective of this study was to describe drug use and estimate the prevalence of off-label and unlicensed drugs in a pediatric intensive care unit of a tertiary care Spanish hospital. Population and methods. Cross-sectional, observational study with a single cohort of children admitted to a pediatric intensive care unit. The study was conducted in 2017. Each drug prescription, its conditions of use and administration were reviewed. In addition, the summary of product characteristics of drugs used were analyzed in order to identify whether they were used according to their conditions of authorization, or whether they were used in an off-label or unlicensed manner. Results. The sample included 97 patients. At least one off-label or unlicensed drug was administered to 74.2% (n = 72) of patients; 23.8% (n = 243) corresponded to off-label prescriptions and 8.7% (n = 89), unlicensed prescriptions. A sub-analysis by age group showed that the age group that received a higher number of total prescriptions (n = 611) and a higher percentage of off-label and/or unlicensed drug prescriptions (38.4%) was under 2 years of age. Conclusions. Off-label and/or unlicensed drug prescription is a common practice in the pediatric intensive care unit. This study allowed us to document the complexity of therapeutics in children.

Effect of preoperative anxiety level on postoperative pain, analgesic consumption in patients undergoing laparoscopic sleeve gastrectomy: an observational cohort study

Abstract Backgraund: This prospective observational cohort study aimed to investigate the relationship between preoperative anxiety levels and postoperative pain and analgesic requirement in patients undergoing laparoscopic sleeve gastrectomy. Methods: Forty two female patients with body mass index ≥ 35, who underwent laparoscopic sleeve gastrectomy for treatment of obesity were included in the study. Spielberger's state and trait anxiety scales were used in this study. Demographic data of the patients, anesthetic and analgesic drugs during the surgery, pain levels measured with verbal analog scale at the postoperative 1st, 4th, 12th, and 24th hour, sedation levels measured with the Ramsay sedation scale, and the amount of analgesic consumed were recorded. Anesthesiologist, surgeon, and patient were not informed of the anxiety level results. The relationship between preoperative anxiety and postoperative pain and analgesic consumption was evaluated by Spearman's correlation analysis. Stepwise multiple linear regression analysis was applied. Normal Distribution control was performed by applying the Shapiro-Wilk test to residual values obtained from the final model. Results: There was no relationship between trait anxiety level and postoperative pain and analgesic consumption. A correlation was found between state anxiety level and pain level up to 24 hours and analgesic consumption (p < 0.05). According to the obtained model it had been observed that the university graduates consumed more analgesic compared to other education level groups. Conclusion: In this study, a relationship was found between preoperative state anxiety level and 24-hour pain scores and analgesic consumption in patients who underwent laparoscopic sleeve gastrectomy under general anesthesia.

Implementation of an ERAS program in patients undergoing thoracic surgery at a third-level university hospital: an ambispective cohort study

Abstract Objective To analyze the effects of an ERAS program on complication rates, readmission, and length of stay in patients undergoing pulmonary resection in a tertiary university hospital. Methods Ambispective cohort study with a prospective arm of 50 patients undergoing thoracic surgery within an ERAS program (ERAS group) versus a retrospective arm of 50 patients undergoing surgery before the protocol was implemented (Standard group). The primary outcome was the number of patients with 30-day surgical complications. Secondary outcomes included ERAS adherence, non-surgical complications, mortality, readmission, reintervention rate, pain, and hospital length of stay. We performed a multivariate logistic analysis to study the correlation between outcomes and ERAS adherence. Results In the univariate analysis, we found no difference between the two groups in terms of surgical complications (Standard 18 [36%] vs. ERAS 12 [24%], p = 0.19). In the ERAS group, only the readmission rate was significantly lower (Standard 15 [30%] vs. ERAS 6 [12%], p = 0.03). In the multivariate analysis, ERAS adherence was the only factor associated with a reduction in surgical complications (OR [95% CI] = 0.02 [0.00, 0.59], p = 0.03) and length of stay (HR [95% CI] = 18.5 [4.39, 78.4], p < 0.001). Conclusions The ERAS program significantly reduced the readmission rate at our hospital. Adherence to the ERAS protocol reduced surgical complications and length of stay.

Early mobilization after total hip or knee arthroplasty: a substudy of the POWER. 2 study

Abstract Background Early mobilization after surgery is a cornerstone of the Enhanced Recovery After Surgery (ERAS) programs in total hip arthroplasty (THA) or total knee arthroplasty (TKA). Our goal was to determine the time to mobilization after this surgery and the factors associated with early mobilization. Methods This was a predefined substudy of the POWER.2 study, a prospective cohort study conducted in patients undergoing THA and TKA at 131 Spanish hospitals. The primary outcome was the time until mobilization after surgery as well as determining those perioperative factors associated with early mobilization after surgery. Results A total of 6093 patients were included. The median time to achieve mobilization after the end of the surgery was 24 hours [16-30]. 4,222 (69.3%) patients moved in ≤ 24 hours after surgery. Local anesthesia [OR = 0.80 (95% confidence interval [CI]: 0.72-0.90); p= 0.001], surgery performed in a self-declared ERAS center [OR = 0.57 (95% CI: 0.55-0.60); p< 0.001], mean adherence to ERAS items [OR = 0.93 (95% CI: 0.92-0.93); p< 0.001], and preoperative hemoglobin [OR = 0.97 (95% CI: 0.96-0.98); p< 0.001] were associated with shorter time to mobilization. Conclusions Most THA and TKA patients mobilize in the first postoperative day, early time to mobilization was associated with the compliance with ERAS protocols, preoperative hemoglobin, and local anesthesia, and with the absence of a urinary catheter, surgical drains, epidural analgesia, and postoperative complications. The perioperative elements that are associated with early mobilization are mostly modifiable, so there is room for improvement.
