[Scientific production from public hospitals of the City of Buenos Aires, 2017]. / Producción científica de los hospitales públicos de la Ciudad de Buenos Aires, 2017.

The number of publications in the scientific literature coming from an institution is an indicator of its scientific production. The scientific production of the hospitals of the Government of the City of Buenos Aires (GCBA) has been evaluated previously, but without discriminating how much of that production corresponded to other academic institutions settled there (University of Buenos Aires, UBA, National Council of Scientific Research and Techniques, CONICET). Our objective was to evaluate the publications included in PubMed that correspond to hospitals of the GCBA, describe their main characteristics, and discriminate the contribution of other academic institutions (UBA and CONICET). It is a cross-sectional study based on a PubMed search, using the name of each of the 34 GCBA hospitals, CONICET and UBA in the "affiliation" field. In total, 2727 publications from GCBA hospitals were identified (4.6% of Argentine publications); 73.9% in English, 78.9% in relation to humans, 37.2% in the last 5 years; 6.4% with high level of evidence (clinical trials and meta-analysis), and 28.4% including children. Compared to the national total, the GCBA publications include fewer works in English, more research in humans, more clinical trials and more research in children. Of the publications corresponding to hospitals of the GCBA, 90.4% did not share the affiliation with CONICET or with UBA. In conclusion, the GCBA hospitals generated 4.6% of the total Argentine publications in PubMed; and 90% of these was not shared with UBA or CONICET. Publications from GCBA institutions include more clinical trials and research in children.

Perinatal Asphyxia Reduces the Number of Reelin Neurons in the Prelimbic Cortex and Deteriorates Social Interaction in Rats.

Obstetrical complications of perinatal asphyxia (PA) can often induce lesions that, in the long-term, manifest as schizophrenia. A deterioration of the medial prefrontal cortex (mPFC) and a reduction in the number of GABAergic neurons are commonly observed in the pathophysiology of schizophrenia. In this study, we investigated the link between PA, reelin and calbindin diminution and psychiatric diseases that involve social interaction deficits. This was achieved by observing the effect of 19 min of asphyxia on both subpopulations of GABAergic neurons. PA was produced by water immersion of fetus-containing uterus horns removed by cesarean section from ready-to-deliver rats. PA generated a significant and specific decrease in the number of reelin-secreting neurons in mPFC layer VI [F(2, 6) = 8.716, p = 0.016; PA vs. vaginal controls (VC), p = 0.03, and PA vs. cesarean controls (CC), p = 0.022]. This reduction reached approximately 60% on average. Changes in the percentage of reelin neurons including all the cortex layers did not achieve a significant outcome but a trend: CC % 10.61 ± 1.34; PA % 8.64 ± 1.71 [F(2, 6) = 1.299, p = 0.33]. In the case of calbindin, there was a significant decrease in cell density in the PA group [2-way repeated-measures ANOVA, F(1, 4) = 13.03, p = 0.0226]. The multiple-comparisons test showed significant differences in the superficial aspect of layer II (Sidak test for multiple comparisons CC vs. PA at 200 µm: p = 0.003). A small, but significant difference could be seen when the distance from the pia mater to the start of layer VI was analyzed (CC mean ± SEM = 768.9 ± 8.382; PA mean ± SEM = 669.3 ± 17.75; p = 0.036). Rats exposed to PA showed deterioration in social interactions, which manifested as a decrease in play soliciting. In this model, which involved severe/moderate asphyxia, we did not find significant changes in locomotive activity or anxiety indicators in the open field task. The loss of reelin neurons could be conducive to the shrinkage of the prelimbic cortex through the reduction in neuropil and the deterioration of the function of this structure.

Assessment of the usability of teleconsultations during the COVID-19 pandemic at a children's hospital. / Evaluación de la usabilidad de la teleconsulta durante la pandemia por COVID-19 en un hospital pediátrico.

Introduction. Usability in a telemedicine system directly affects the efficiency and effectiveness of remote health care. Objective. To assess the usability of teleconsultations during the COVID-19 pandemic. Population and method. This was a cross-sectional study. The caregivers of children aged 1 month to 12 years were included. Usability was assessed with the Telehealth Usability Questionnaire, adapted to Spanish. Socioeconomic data were also assessed. Results. The response rate was 70.2% (n = 221). Most responders were women whose average age was 33 years, had completed secondary education and had public health insurance. Of them, 87.8% selected telephone health care and 88.2% had their first teleconsultation. The overall satisfaction was high, with lower scores for ease of use and learning how to use video calls. Conclusion. Regardless of modality, the usability of teleconsultations by caregivers of children aged 1 month to 12 years was adequate.

Thirty-day readmissions in children with complex chronic conditions.

INTRODUCTION: The rate of hospital readmission within 30 days of discharge is a quality indicator in health care. Paediatric patients with complex chronic conditions have high readmission rates. Failure in the transition between hospital and home care could explain this phenomenon. OBJECTIVES: To estimate the incidence rate of 30-day hospital readmission in paediatric patients with complex chronic conditions, estimate how many are potentially preventable and explore factors associated with readmission. MATERIALS AND METHOD: Cohort study including hospitalised patients with complex chronic conditions aged 1 month to 18 years. Patients with cancer or with congenital heart disease requiring surgical correction were excluded. The outcomes assessed were 30-day readmission rate and potentially preventable readmissions. We analysed sociodemographic, geographic, clinical and transition to home care characteristics as factors potentially associated with readmission. RESULTS: The study included 171 hospitalizations, and 28 patients were readmitted within 30 days (16.4%; 95% CI, 11.6%-22.7%). Of the 28 readmissions, 23 were potentially preventable (82.1%; 95% CI, 64.4%-92.1%). Respiratory disease was associated with a higher probability of readmission. There was no association between 30-day readmission and the characteristics of the transition to home care. CONCLUSIONS: The 30-day readmission rate in patients with complex chronic disease was 16.4%, and 82.1% of readmissions were potentially preventable. Respiratory disease was the only identified risk factor for 30-day readmission.

[Exclusive breastfeeding and disease evolution in hospitalized infants with bronchiolitis]. / Lactancia materna exclusiva y evolución de la enfermedad en lactantes hospitalizados por bronquiolitis.

Bronchiolitis is the main reason for hospitalization in infancy. Breastfeeding is a protective factor aga inst infections, however, although there is evidence that breastfeeding could prevent hospitalizations due to bronchiolitis, its effect in patients already hospitalized because of this disease is less clear. OBJECTIVE: To evaluate if there are differences in the evolution of patients hospitalized due to bronchiolitis fed with exclusive breastfeeding (EBF) vs. breast milk substitutes (BMS). PATIENTS AND METHOD: Prospec tive cohort study. Children hospitalized due to bronchiolitis aged from 1 to 6 months were included. Evolution was compared with respect to days of hospitalization, days of oxygen therapy, requirement of high-flow nasal cannula (HFNC), presence of associated pneumonia, transfer to intensive care, and death. RESULTS: During the study period, 131 infants hospitalized due to bronchiolitis met the selection criteria, 54 were fed with EBF, 29 with BMS, and 48 received mixed feeding. The EBF group required significantly fewer days of oxygen therapy (5.1 ± 2.4 vs. 6.6 ± 3.5; p < 0.02) and hospitalization (7.0 ± 2.4 vs. 8.4 ± 3.6; p < 0.04) than the BMS group. Although males in the BMS group required on average more days of hospitalization and oxygen therapy, this difference was not statistically significant. No deaths were recorded in the groups studied. CONCLUSION: Patients fed with EBF required fewer days of oxygen therapy and hospitalization than those who received BMS.

The digital divide among caregivers of pediatric patients aged 0 to 12 years. Design and validation of a questionnaire. / Brecha digital en cuidadores de pacientes pediátricos de 0 a 12 años. Diseño y validación de un cuestionario.

Introduction. Health care strategies based on information and communication technologies (ICTs) may perpetuate health inequity, especially among vulnerable populations. In our setting, there are few validated tools to assess access to ICTs in pediatrics. Objectives. To develop and validate a questionnaire to assess ICT access among caregivers of pediatric patients. To describe the characteristics of ICT access and assess whether there is a correlation among the three levels of the digital divide. Population and methods. We developed and validated a questionnaire and then administered it to the caregivers of children aged 0-12 years. The outcome variables were the questions in the three levels of the digital divide. We also assessed sociodemographic variables. Results. We administered the questionnaire to 344 caregivers. Among them, 93% had their own cell phone and 98.3% had Internet access via a data network; 99.1% communicated via WhatsApp messages; 28% had had a teleconsultation. The correlation among the questions was null or low. Conclusion. The validated questionnaire allowed us to establish that the caregivers of pediatric patients aged 0-12 years mostly own a mobile phone, access the Internet via a data network, communicate mainly through WhatsApp, and obtain few benefits through ICTs. The correlation among the different components of ICT access was low.

[Tumor lysis syndrome after the administration of corticosteroids in an adolescent without confirmed neoplastic disease. Case Reports]. / Síndrome de lisis tumoral secundario a la administración de corticoides en una adolescente sin enfermedad neoplásica confirmada: reporte de un caso.

Tumor lysis syndrome is a potentially lethal complication and constitutes with infections the most frequent oncological emergency. In children, this condition can be secondary to neoplastic diseases, with corticosteroids being a triggering factor. This paper presents the case of an adolescent patient, without known or obvious neoplasms, who developed a tumor lysis syndrome after the administration of corticosteroids due to suspected respiratory infection. The clinical presentation and differential diagnoses are discussed. Special focus is placed on the administration of corticosteroids in clinical conditions with weak scientific evidence. The use of systemic corticosteroids in acute respiratory infections should be evaluated in the clinical context and only indicated in situations with proven effectiveness.

El síndrome de lisis tumoral es una complicación potencialmente letal y constituye, junto con las infecciones, la emergencia oncológica más frecuente. En pediatría, este cuadro puede ser secundario a enfermedades neoplásicas, y los corticoides son un factor desencadenante. En este trabajo se presenta el caso de una paciente adolescente, sin neoplasias conocidas o evidentes, que desarrolló un síndrome de lisis tumoral luego de la administración de corticoides por sospecha de una infección respiratoria. Se discute la forma de presentación y los diagnósticos diferenciales del cuadro clínico inicial. Se hace especial foco en la administración de corticoides en cuadros clínicos en los que no existe evidencia científica que respalde fuertemente su indicación. El uso de corticosteroides sistémicos en infecciones respiratorias agudas debe ser evaluado en el contexto clínico y solo debe indicarse en situaciones con probada efectividad.

Hypothermia prevents nitric oxide system changes in retina induced by severe perinatal asphyxia.

One-third of asphyctic neonates develop long-term neurological injuries, including several degrees of ischemic proliferative retinopathy (IPR) such as retinopathy of prematurity (ROP). Given that the retina is altered by perinatal asphyxia, our aim was to study the effects of nitric oxide (NO) in the retina in order to analyze its impact on the retinal injury. Application of hypothermia was evaluated as preventive treatment. Sprague-Dawley rats were subjected to perinatal asphyxia [either at 37°C (PA group) or at 15°C (HYP group)]. Full-term rats were used as controls (CTL). A significantly increased activity of both constitutive NO synthase (nNOS, Ca(2+)-dependent) and inducible NO synthase (iNOS, Ca(2+)-independent) was observed in PA retinas from 21 days old up to 60 days old with respect to age-matched CTL, with a significant increase along the time course in the PA. nNOS was immunolocalized at amacrine, horizontal, and ganglion cells of the PA group, with a significant increase in relative optical density (R.O.D.), cellular area, and number of cells. iNOS immunoreactivity was observed in the inner nuclear layer and in the internal Müller cell processes of PA, with a significant increase in R.O.D. and colocalizing with GFAP in the 60-day-old PA group. Six nitrated protein species were increased in retinas from PA rats. Nitrotyrosine immunoreactivity showed a localization similar to that of iNOS, with increased R.O.D. in the PA group and colocalization with GFAP in 60-day-old animals. HYP prevented all the changes observed in PA rats. Although the NO system displays changes induced by hypoxia-ischemia, hypothermia application shows a strong protective effect.

Hospital readmissions at a tertiary care children's hospital: Prevalence, associated characteristics, and preventability. / Reingresos hospitalarios en un hospital pediátrico de tercer nivel: prevalencia, características asociadas y prevenibilidad.

INTRODUCTION: Hospital readmissions in pediatrics are a severe, potentially avoidable problem of health systems. In our setting, there is little information about this topic. OBJECTIVE: To estimate the rate of readmissions, the proportion of potentially preventable readmissions, and their associated characteristics. MATERIAL AND METHODS: Cross-sectional study including hospital readmissions of patients aged 0-18 years, admitted to a tertiary care children's hospital between January 1st and December 31st, 2018. Readmissions were assessed as potentially preventable based on whether they were or not related to the previous admission. RESULTS: Out of 8228 hospital admissions recorded in the study period, the rate of readmissions for any cause was 10 % at 30 days and 7.1 % at 15 days. The proportion of readmissions classified as potentially preventable was 47.9 % at 30 days and 47.5 % at 15 days. No statistically significant differences were observed between readmissions at 30 and 15 days in terms of patient age, health insurance, presence of chronic disease or cause of readmission. CONCLUSION: The rate of hospital readmissions was 10 % at 30 days and 7.1 % at 15 days of discharge; almost half of them were considered potentially preventable.

Introducción. Los reingresos hospitalarios en pediatría representan un problema grave, potencialmente evitable, en los sistemas de salud. Existe poca información sobre el tema en nuestro medio. Objetivo. Estimar la tasa de reingreso, la proporción de reingresos potencialmente prevenibles y las características asociadas a estos. Material y métodos. Estudio transversal que incluyó reingresos hospitalarios de pacientes de 0 a 18 años, internados en un hospital pediátrico de tercer nivel entre el 1 de enero de 2018 y el 31 de diciembre de 2018. Se evaluó si los reingresos fueron potencialmente prevenibles según tuvieran o no relación con el ingreso previo. Resultados. Sobre 8228 ingresos hospitalarios contabilizados en el período de estudio, se observó una tasa de reingresos por cualquier causa de 10 % a 30 días y del 7,1 % a 15 días. La proporción de reingresos clasificados como potencialmente prevenibles fue de 47,9 % a los 30 días y de 47,5 % a 15 días. No se observaron diferencias estadísticamente significativas entre los reingresos a 30 y a 15 días respecto de la edad de los pacientes, la cobertura de salud, la presencia de una enfermedad crónica ni la causa del reingreso. Conclusión. La tasa de reingresos hospitalarios fue de 10 % a 30 días del egreso y de 7,1 % a 15 días; casi la mitad de ellos se consideraron potencialmente prevenibles.

Use of a Flexible Catheter for the Administration of Subcutaneous Insulin in Diabetic Ketoacidosis: A Feasibility Controlled Clinical Trial.

BACKGROUND: Although intravenous insulin administration is the standard of care in diabetic ketoacidosis (DKA), subcutaneous insulin administration could be a suitable alternative in resource-limited settings, but pain caused by hourly insulin applications are limiting factors for using it, especially in children. We aimed to assess whether the use of a flexible subcutaneous catheter improves comfort in patients with DKA compared with the usual hourly injections' treatment. We also compared the evolution of metabolic variables in patients with DKA using both insulin administration systems. METHODS: Randomized feasibility controlled open trial, comparing 2 ways (flexible catheter and steel needle) for the initial insulin administration in children with DKA, who were randomly selected to receive subcutaneous insulin by a flexible catheter or using standard needles. The main outcome was pain, assessed hourly and secondary outcome time to achieve ketoacidosis resolution. RESULTS: Twenty subjects were included (10 by group). There were no differences between groups in baseline lab values (glycemia, urea, sodium, bicarbonate and pH). Pain assessment at first insulin administration was significantly lower in the intervention group (4.5 vs 0 points; P = 0.001). Similar differences between both treatment arms were observed in every pain assessment. There were no differences between groups regarding the time elapsed to achieve ketoacidosis resolution. (11.4±4.3 vs 16±8.4; P = 0.12). No adverse events or DKA complications were observed. CONCLUSIONS: The use of a flexible catheter reduced the pain associated with subcutaneous insulin administration in nonsevere DKA. The flexible subcutaneous catheter could be a safe alternative for the treatment of uncomplicated DKA in resource-limited settings.

Hypothermia prevents the development of ischemic proliferative retinopathy induced by severe perinatal asphyxia.

Obstetric complications, such as perinatal asphyxia, may cause retinal injuries as retinopathy of prematurity (ROP), a type of ischemic proliferative retinopathy. Up to date there are no appropriate experimental models for studying the long-term sequels of this disease. In the present work, we present an experimental model of perinatal asphyxia which shows structural and ultrastructural retinal alterations at the most inner layers of the retina, such as neurodegeneration, development of neoformed vessels and glial reaction, which are compatible with the histopathological description of ROP. Besides, the application of hypothermia during perinatal asphyxia showed effective results preventing cellular and morphological alterations. This study may contribute to the development of therapies in order to either ameliorate or prevent retinal damage. In this manner, hypothermia may improve life quality and decrease medical, family and social costs of these avoidable causes of blindness.

Reingreso hospitalario a 30 días en pacientes pediátricos con enfermedades crónicas complejas / Thirty-day readmissions in children with complex chronic conditions

Introducción: La tasa de reingreso hospitalario a 30 días del alta es una medida de calidad de la atención médica. Los pacientes pediátricos con enfermedades crónicas complejas tienen altas tasas de reingreso. La falla en la transición entre el cuidado hospitalario y domiciliario podría explicar este fenómeno. Objetivos: Estimar la tasa de incidencia de reingreso hospitalario a 30 días en pacientes pediátricos con enfermedades crónicas complejas, estimar cuántos son potencialmente prevenibles y explorar posibles factores asociados a reingreso. Materiales y método: Estudio de cohorte prospectivo incluyendo pacientes hospitalizados con enfermedades crónicas complejas de un mes a 18 años de edad. Se excluyeron pacientes con enfermedad oncológica y cardiopatías congénitas. Se evaluaron el reingreso a 30 días y el reingreso potencialmente prevenible. Se valoraron características sociodemográficas, geográficas, clínicas y de la transición hacia el cuidado domiciliario. Resultados: Se incluyeron 171 hospitalizaciones; dentro de los 30 días reingresaron 28 pacientes (16,4%; IC95% 11,6-22,7). De los 28 reingresos, 23 (82,1%; IC95% 64,4-92,1) fueron potencialmente prevenibles. La enfermedad respiratoria se asoció con mayor probabilidad de reingreso. No se encontró asociación entre el reingreso a 30 días y los factores de la transición al cuidado domiciliario evaluados. Conclusiones: La tasa de reingreso a 30 días en pacientes con enfermedad crónica compleja fue del 16,4%, y el 82,1% fueron potencialmente prevenibles. Únicamente la enfermedad respiratoria se comportó como factor de riesgo para reingreso a 30 días.(AU)

Concerted regulation of renal plasma flow and glomerular filtration rate by renal dopamine and NOS I in rats on high salt intake.

Under high sodium intake renal dopamine (DA) increases while NOS I expression in macula densa cells (MD) decreases. To explore whether renal DA and NOS I, linked to natriuresis and to the stability of the tubuloglomerular feedback, respectively, act in concert to regulate renal plasma flow (RPF) and glomerular filtration rate (GFR). Male Wistar rats were studied under a normal sodium intake (NS, NaCl 0.24%) or a high sodium intake (HS, NaCl 1% in drinking water) during the 5 days of the study. For the last two days, the specific D1-like receptor antagonist SCH 23390 (1 mg kg bwt-1 day-1, sc) or a vehicle was administered. HS intake increased natriuresis, diuresis, and urinary DA while it decreased cortical NOS I expression (P < 0.05 vs. NS), Nicotinamide adenine dinucleotide phosphate diaphorase (NADPH-d) activity in MD (P < 0.001 vs. NS) and cortical nitrates+nitrites (NOx) production (NS 2.04 ± 0.22 vs. HS 1.28 ± 0.10 nmol mg protein-1, P < 0.01). Treatment with SCH 23390 to rats on HS sharply decreased hydroelectrolyte excretion (P < 0.001 vs. HS) while NOS I expression, NADPH-d activity and NOx production increased (P < 0.05 vs. HS for NOS I and P < 0.001 vs. HS for NADPH-d and NOx). SCH 23390 increased RPF and GFR in HS rats (P < 0.01 HS+SCH vs. HS). It did not cause variations in NS rats. Results indicate that when NS intake is shifted to a prolonged high sodium intake, renal DA through the D1R, and NOS I in MD cells act in concert to regulate RPF and GFR to stabilize the delivery of NaCl to the distal nephron.

Síndrome de lisis tumoral secundario a la administración de corticoides en una adolescente sin enfermedad neoplásica confirmada: reporte de un caso / Tumor lysis syndrome after the administration of corticosteroids in an adolescent without confirmed neoplastic disease. Case report

El síndrome de lisis tumoral es una complicación potencialmente letal y constituye, junto con las infecciones, la emergencia oncológica más frecuente. En pediatría, este cuadro puede ser secundario a enfermedades neoplásicas, y los corticoides son un factor desencadenante. En este trabajo se presenta el caso de una paciente adolescente, sin neoplasias conocidas o evidentes, que desarrolló un síndrome de lisis tumoral luego de la administración de corticoides por sospecha de una infección respiratoria. Se discute la forma de presentación y los diagnósticos diferenciales del cuadro clínico inicial. Se hace especial foco en la administración de corticoides en cuadros clínicos en los que no existe evidencia científica que respalde fuertemente su indicación. El uso de corticosteroides sistémicos en infecciones respiratorias agudas debe ser evaluado en el contexto clínico y solo debe indicarse en situaciones con probada efectividad.

Tumor lysis syndrome is a potentially lethal complication and constitutes with infections the most frequent oncological emergency. In children, this condition can be secondary to neoplastic diseases, with corticosteroids being a triggering factor. This paper presents the case of an adolescent patient, without known or obvious neoplasms, who developed a tumor lysis syndrome after the administration of corticosteroids due to suspected respiratory infection.The clinical presentation and differential diagnoses are discussed. Special focus is placed on the administration of corticosteroids in clinical conditions with weak scientific evidence. The use of systemic corticosteroids in acute respiratory infections should be evaluated in the clinical context and only indicated in situations with proven effectiveness.

Reingresos hospitalarios en un hospital pediátrico de tercer nivel: Prevalencia, características asociadas y prevenibilidad / Hospital readmissions at a tertiary care children's hospital: Prevalence, associated characteristics, and preventability

Introducción. Los reingresos hospitalarios en pediatría representan un problema grave, potencialmente evitable, en los sistemas de salud. Existe poca información sobre el tema en nuestro medio. Objetivo. Estimar la tasa de reingreso, la proporción de reingresos potencialmente prevenibles y las características asociadas a estos. Material y métodos. Estudio transversal que incluyó reingresos hospitalarios de pacientes de 0 a 18 años, internados en un hospital pediátrico de tercer nivel entre el 1 de enero de 2018 y el 31 de diciembre de 2018. Se evaluó si los reingresos fueron potencialmente prevenibles según tuvieran o no relación con el ingreso previo. Resultados. Sobre 8228 ingresos hospitalarios contabilizados en el período de estudio, se observó una tasa de reingresos por cualquier causa de 10 % a 30 días y del 7,1 % a 15 días. La proporción de reingresos clasificados como potencialmente prevenibles fue de 47,9 % a los 30 días y de 47,5 % a 15 días. No se observaron diferencias estadísticamente significativas entre los reingresos a 30 y a 15 días respecto de la edad de los pacientes, la cobertura de salud, la presencia de una enfermedad crónica ni la causa del reingreso. Conclusión. La tasa de reingresos hospitalarios fue de 10 % a 30 días del egreso y de 7,1 % a 1 días; casi la mitad de ellos se consideraron potencialmente prevenibles

Introduction. Hospital readmissions in pediatrics are a severe, potentially avoidable problem of health systems. In our setting, there is little information about this topic. Objective. To estimate the rate of readmissions, the proportion of potentially preventable readmissions, and their associated characteristics. Material and methods. Cross-sectional study including hospital readmissions of patients aged 0-18 years, admitted to a tertiary care children's hospital between January 1st and December 31st, 2018. Readmissions were assessed as potentially preventable based on whether they were or not related to the previous admission. Results. Out of 8228 hospital admissions recorded in the study period, the rate of readmissions for any cause was 10 % at 30 days and 7.1 % at 15 days. The proportion of readmissions classified as potentially preventable was 47.9 % at 30 days and 47.5 % at 15 days. No statistically significant differences were observed between readmissions at 30 and 15 days in terms of patient age, health insurance, presence of chronic disease or cause of readmission. Conclusion. The rate of hospital readmissions was 10 % at 30 days and 7.1 % at 15 days of discharge; almost half of them were considered potentially preventable.
