ABSTRACT

BACKGROUND: Data from the sentinel surveillance system of severe acute respiratory infections in Spain were used to estimate the impact of administration of nirsevimab to children born from 1 April 2023 onwards. METHODS: Estimated RSV hospitalisations in < 1-year-olds during weeks 40, 2023, to 8, 2024, were compared to the number that would be expected after accounting for the background change in RSV circulation in the 2023/24 season, compared to 2022/23. RESULTS: We estimated 9364-9875 RSV hospitalisations less than expected, corresponding to a 74%-75% reduction.

ABSTRACT

Objetivos. Se describe clínica y epidemiológicamente unbrote de infección gastrointestinal por Salmonella entéricaser. (serotipo) Enteritidis, en una escuela infantil urbana, queconllevó elevada morbilidad e importante alarma social. La comunicación inmediata, así como el estudio adecuado del brote,en ambas vertientes, permitieron identificar el patógeno y establecer medidas de control en un plazo razonable de tiempo.Se discuten aspectos controvertidos como la indicación de antibioterapia o el momento de cierre del centro.Material y métodos. Se recogió retrospectivamente información clínica, analítica y epidemiológica, y se revisó la metodología y resultados del estudio del brote.Resultados. 57 niños (3-45 meses) de 92 asistentes al centro, fueron afectados y tuvieron confirmación microbiológica.Diarrea y fiebre fueron los principales síntomas. 74% acudieronal hospital, y 37% ingresaron, (estancia media 3,3 días). Fueronfactores asociados al ingreso: deshidratación, elevación significativa de reactantes de fase aguda y coagulopatía. 12 recibieroncefotaxima parenteral. Se registraron 2 complicaciones: 1 bacteriemia y 1 reingreso. La sospecha inicial del origen del brotefueron los alimentos, pero el análisis de las muestras testigofue negativo. 5 trabajadores fueron positivos (2 sintomáticos).Vigilancia Epidemiológica concluyó que el origen probable delbrote fue un portador asintomático y la manipulación incorrectade pañales. El centro permaneció cerrado 8 días. Se realizaronmedidas de limpieza y desinfección, instrucción sobre cambio depañales y seguimiento de portadores.Conclusiones. La agrupación en tiempo y espacio de casos debe ser notificada inmediatamente para el control precozdel brote. Los niños pueden presentar formas graves de gastroenteritis por Salmonella. (AU)


Objectives. We describe clinically and epidemiologically anoutbreak of gastrointestinal infection by Salmonella entericaser. (serotype) Enteritidis in an urban infant school, which ledto high morbidity and significant social alarm. The immediatecommunication, as well as the adequate study of the outbreak, inboth aspects, allowed identifying the pathogen and establishingcontrol measures in a reasonable period of time. Controversialaspects such as the indication of antibiotherapy or the momentof closing the center are discussed.Methods. We retrospectively collected clinical, analyticaland epidemiological information and we reviewed themethodology of the outbreak study and its results.Results. A total of 57 children (3-45 months), wereaffected and had microbiological confirmation. Diarrhea andfever were the main symptoms. 74% went to the hospital and37% were admitted (mean stay 3.3 days). Factors associatedwith admission were: dehydration, significant elevation ofacute phase reactants and coagulopathy. Twelve patientsreceived parenteral cefotaxime. There were 2 complications:1 bacteremia and 1 readmission. The initial suspicion ofthe origin of the outbreak was food, but the analysis of thecontrol samples was negative. Five workers were positive (2symptomatic). Epidemiologic Surveillance concluded that theprobable origin of the outbreak was an asymptomatic carrierand improper diapers handling. The center was closed for 8days. Cleaning and disinfection measures were carried out, aswell as instruction on diaper changing, and the carriers werefollowedConclusions. Clustering in time and space of cases shouldbe reported immediately for early control of the outbreak.Children may present severe forms of Salmonella gastroenteritis (AU)

ABSTRACT

The absence of the mouse cell surface receptor CD38 in Cd38-/- mice suggests that this receptor acts as a positive regulator of inflammatory and autoimmune responses. Here, we report that, in the context of the chronic graft-versus-host disease (cGVHD) lupus inducible model, the transfer of B6.C-H2bm12/KhEg(bm12) spleen cells into co-isogenic Cd38-/- B6 mice causes milder lupus-like autoimmunity with lower levels of anti-ssDNA autoantibodies than the transfer of bm12 spleen cells into WT B6 mice. In addition, significantly lower percentages of Tfh cells, as well as GC B cells, plasma cells, and T-bet+CD11chi B cells, were observed in Cd38-/- mice than in WT mice, while the expansion of Treg cells and Tfr cells was normal, suggesting that the ability of Cd38-/- B cells to respond to allogeneic help from bm12 CD4+ T cells is greatly diminished. The frequencies of T-bet+CD11chi B cells, which are considered the precursors of the autoantibody-secreting cells, correlate with anti-ssDNA autoantibody serum levels, IL-27, and sCD40L. Proteomics profiling of the spleens from WT cGVHD mice reflects a STAT1-driven type I IFN signature, which is absent in Cd38-/- cGVHD mice. Kidney, spleen, and liver inflammation was mild and resolved faster in Cd38-/- cGVHD mice than in WT cGVHD mice. We conclude that CD38 in B cells functions as a modulator receptor that controls autoimmune responses.

ABSTRACT

The incidence of acute poisonings has increased in recent years and constitutes approximately 2% of the services provided by the Emergency Department currently. The objective of this study is to describe the frequency and characteristics of the intoxications treated at the Central University Hospital of Asturias during 2015 from biochemical-analytical, epidemiological and medical-legal perspectives. We conducted a retrospective study and a descriptive analysis of the clinical and sociodemographic variables included in the acute intoxication (AI) protocol at the national level. This hospital treated 2,478 cases of acute poisoning, representing 2.3% of the emergencies treated and corresponding to an incidence of 764 cases/100,000 inhabitants/year with an age ranging from under 1 year to over 80 years. The average age of the patients was 43.6 (SD = 16.6) years. Of these patients, 59.4% were males with an average age of 44 (SD = 16.8) years, and women represented 43.1% with an average age of 42.8 (SD = 16.5) years. These intoxications have a frequency of 47.2% during the weekend, while 37.4% occur between June and September. Acute voluntary intoxication is the most frequent intentionality, corresponding to 83.2% of the cases. We must point out that the medical records register 16.8% of the cases as suicide attempts. Ethanol and benzodiazepines are the most commonly-used toxics. These intoxications are treated in the Emergency Department without requiring hospitalization and have a very low mortality rate.


La incidencia de las intoxicaciones agudas ha aumentado en los últimos años, y actualmente constituye aproximadamente el 2% de las atenciones sanitarias llevadas a cabo por los Servicios de Urgencias. El objetivo de este estudio es describir la frecuencia y características de las intoxicaciones atendidas en el Hospital Universitario Central de Asturias durante el año 2015 desde la perspectiva bioquímica-analítica, epidemiológica y médico-legal. Se realizó un estudio retrospectivo y un análisis descriptivo de las variables clínicas y sociodemográficas incluidas en el protocolo de intoxicación aguda a nivel nacional. Este hospital atendió 2478 casos de intoxicaciones agudas representando el 2,3% de las urgencias atendidas y que corresponde a una incidencia de 764 casos/100000 habitantes/año con un rango de edad de menores de 1 año a mayores de 80 años. La edad media de los pacientes atendidos fue de 43,6 (DE = 16,6) años. El 59,4% de los pacientes eran varones con una edad media de 44 (DE = 16,8) años, las mujeres representaban el 43,1% y su edad media era de 42,8 (DE = 16,5) años. El 47,2% de estas intoxicaciones ocurren durante el fin de semana y el 37,4% se dan entre junio y septiembre. La intencionalidad más frecuente es la intoxicación aguda voluntaria correspondiente al 83,2% de los casos. Cabe destacar que el 16,8% de los casos están referenciados en su historia clínica como intentos de suicidio. Los tóxicos más empleados son el etanol y las benzodiacepinas. Estas intoxicaciones son resueltas en el Servicio de Urgencias sin requerir ingreso hospitalario y poseen una tasa de mortalidad muy baja.
