RESUMO

INTRODUCTION: The clinical presentation of pregnant women with COVID-19 varied according to the time of the pandemic. OBJECTIVE: The clinic, complications and lethality were described, as well as a comparative analysis of the clinical presentation during the first two pandemic waves of pregnant and postpartum women with COVID-19. METHODS: An observational prospective cohort study of pregnant women assisted in the Municipal Maternity of San Isidro was carried out between 04/01/2020 and 07/31/21. RESULTS: The infection was confirmed in 103 pregnant women, 76.7% had a mild condition, 18.4% moderate and 4.8% severe. 59% were assisted by telemedicine, 41% were admitted and 2.9% required mechanical ventilation. Most had a good evolution and the case fatality rate was < 1% (n = 1). At the time of this analysis, 78% of the women had completed pregnancy. 41% of them presented some type of complication, the most frequent being: premature rupture of the membrane 42%, arterial hypertension and other associated pathologies (including a patient with preeclampsia) 27% and preterm delivery 18%. In the comparative analysis between the first two pandemic waves, there was a higher proportion of moderate/severe cases (p = 0.016) and the indication for mechanical ventilation was significantly higher (p = 0.048) in 2021. DISCUSSION: These findings support the need for prioritize this group of patients to implement preventive strategies.


Introducción: La presentación clínica de las gestantes con COVID-19 fue variando según el momento de la pandemia. Objetivo: Se describió la clínica, complicaciones y letalidad, así como un análisis comparativo de la presentación clínica durante las dos primeras olas pandémicas de las gestantes y puérperas con COVID-19. Métodos: Se realizó un estudio de cohorte prospectivo observacional de las gestantes asistidas en la Maternidad Municipal de San Isidro entre el 01/04/2020 al 31/07/21. Resultados: Se confirmó la infección de 103 gestantes, de las cuales el 76.7% cursó un cuadro leve, 18.4% moderado y 4.8% grave. El 59% fueron asistidas por telemedicina, el 41% se internó, de las cuales el 2.9% requirieron asistencia respiratoria mecánica (ARM). La mayoría tuvo buena evolución y la tasa de letalidad fue < 1% (n = 1). Al momento del presente análisis el 78% de las mujeres habían finalizado la gestación. El 41% de ellas, presentó algún tipo de complicación, siendo lo más frecuente: ruptura prematura de membrana 42%, hipertensión arterial y otras patologías asociadas (incluyendo una paciente con preeclampsia) el 27% y parto pretérmino el 18%. En el análisis comparativo entre las dos primeras olas pandémicas, hubo una mayor proporción de casos moderados/graves (p=0.016) y fue significativamente mayor la indicación de ARM (p=0.048) en el 2021. Discusión: Estos hallazgos avalan la necesidad de priorizar a este grupo de pacientes para implementar estrategias preventivas.

RESUMO

Infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant is usually asymptomatic or mild and appears to be poorly immunogenic at least in unvaccinated individuals. Here, we found that health care workers vaccinated with 2 doses of Sputnik V and a booster dose of ChAdOx1 mount a vigorous neutralizing-antibody response after Omicron breakthrough infection.

RESUMO

OBJECTIVE: Tandem mass spectrometry (MS/MS) is being used for newborn screening since this laboratory testing technology increases the number of metabolic disorders that can be detected from dried blood-spot specimens. In the Community of Madrid, it was implemented in March 2011 and it includes 13 aminoacidopathies, fatty acid oxidation disorders and organic acidemias. The aim of this study was to describe our experience and evaluate the screening positive cases in a period of 9 years (2011-2019). METHODS: During the period of the study, a total of 592.822 neonates were screened with this expanded program by MS/MS in the Community of Madrid. Amino acids, acylcarnitines, and succinylacetone were quantified in all samples that met the quality criteria. Means, medians, percentiles and standard deviation of the analytes and ratios of interest were calculated. RESULTS: 901 patients (0,15 %) with a positive screening test were referred to clinical evaluation. 230 patients were diagnosed of 30 different inborn errors of metabolism (prevalence 1:2577), 11 of which were not included as a target in the Community of Madrid newborn screening program. The global positive predictive value was 25,6 %. During this period of time, two false negative cases were detected. The most prevalent disorders were phenylketonuria/hyperphenylalaninemia and medium chain acyl-CoA dehydrogenase deficiency (1:6444 and 1:13174 respectively). 93 % of the patients were detected in the presymptomatic stage. CONCLUSIONS: During the last 9 years a large number of cases of IEM have been detected with an acceptable global positive predictive value. These results confirm the utility of inborn errors of metabolism newborn screening as a public health program.


OBJETIVO: La tecnología de espectrometría de masas en tándem (MS/MS) en los programas de cribado neonatal ha permitido la detección de gran número de errores congénitos del metabolismo (ECM). En la comunidad de Madrid se implementó en marzo de 2011 incluyendo 13 aminoacidopatías, defectos de la ß-oxidación de ácidos grasos y acidemias orgánicas. El objetivo de este estudio fue describir nuestra experiencia y analizar los casos positivos de cribado en un periodo de 9 años (2011-2019). METODOS: Durante el periodo de estudio se realizó el cribado mediante MS/MS a 592822 recién nacidos en la Comunidad de Madrid. Se cuantificaron aminoácidos, acilcarnitinas y succinilacetona en todas las muestras que cumplieron los criterios de calidad. Se calcularon medias, medianas, percentiles y desviación típica de los analitos y ratios de interés. RESULTADOS: Se derivaron a las unidades clínicas de seguimiento por sospecha de una ECM un total de 901 (0,15 %) casos. Se confirmaron 230 casos de 30 ECM diferentes (prevalencia 1:2577), 11 de los cuales no eran inicialmente objetivo de detección del programa. El valor predictivo positivo global fue de 25,6 %. Durante este periodo se detectaron dos falsos negativos. Las enfermedades con mayor prevalencia fueron fenilcetonuria/hiperfenilalaninemia y deficiencia de acil-CoA deshidrogenasa de cadena media (1:6444 y 1: 13174 respectivamente). 93 % de los casos fueron detectados en fase presintomática. CONCLUSIONES: En estos 9 años de experiencia se han detectado numerosos casos de ECM con un valor predictivo positivo global aceptable. Estos resultados confirman la utilidad del cribado neonatal de ECM como programa de salud pública.

RESUMO

Data on the clinical presentation, risk factors, and outcomes for healthcare personnel (HCP) infected with influenza A H1N1 virus (H1N1) are limited. From June to July 2009, a prospective study was conducted among HCP with influenza-like illness (ILI) at university hospitals in Buenos Aires. A reverse transcription polymerase chain reaction (RT-PCR) was used to diagnose H1N1. A logistic regression model was developed to identify factors associated with H1N1. Among 1519 HCP, 96 (6.3%) were diagnosed with an ILI. Of these, 85 (88.5%) were swabbed for H1N1 detection, with 43 positive cases (2.8%). Seasonal influenza immunization was recorded in 76%. Comparison of H1N1-positive vs. H1N1-negative cases showed that H1N1-positive cases more frequently had asthenia (72% vs. 48%, p = 0.03) and cough (79% vs. 43%, p = 0.008) and less frequently had diarrhoea (9% vs. 29%, p = 0.03) and prior prophylaxis with oseltamivir (5% vs. 31%, p = 0.002). The logistic regression model showed that presence of cough (odds ratio (OR) 6.93, 95% confidence interval (CI) 2.24, 21.4) was associated with an increased risk of H1N1. Prior prophylaxis with oseltamivir (OR 0.08, 95% CI 0.01, 0.43) was associated with a lower probability of H1N1 infection. A high proportion of HCP with an ILI were infected with H1N1. Complication rates were relatively low. Prior prophylaxis with oseltamivir was associated with a lower risk of developing H1N1.
