Increase of pertussis cases in the Vallès region, Catalonia, Spain, September 2023 to April 2024.

We describe a pertussis outbreak in the Vallès region of Catalonia, from September 2023 to April 2024. Incidence was high in children aged 10-14 years compared with previous outbreaks. Limited impact in newborns could be explained by the high vaccination coverage during pregnancy and at 11 months of age in 2022, at 85% and 94.1 %, respectively. A third booster vaccine dose during preadolescence should be considered and vaccination coverage in pregnant women be improved to control future outbreaks.

50 años del Programa de Cribado Neonatal en Cataluña / 50 years of the Neonatal Screening Program in Catalonia

El Programa de Cribado Neonatal de Cataluña (PCNC) se inició en el año 1969, en Barcelona, impulsado por el Dr. Juan Sabater Tobella y apoyado por la Diputación de Barcelona y la Fundación Juan March. Así nació el Instituto de Bioquímica Clínica para acometer funciones asistenciales, de investigación y docencia, con el espíritu de contribuir a la prevención del retraso mental. El PCNC se inició con la detección de la fenilcetonuria (PKU) y en el año 1982 se amplió con la detección del hipotiroidismo congénito. Hacia el año 1990 la cobertura territorial llegó casi al 100% de todos los recién nacidos en Cataluña. En 1999 se amplió el PCNC con la incorporación de la fibrosis quística y tras catorce años, en 2013, se realizó la ampliación más numerosa hasta ahora, con la incorporación de la detección de 19 enfermedades metabólicas hereditarias. En el año 2015 comenzó la detección de la enfermedad de células falciformes y en el 2017 la detección de la inmunodeficiencia combinada grave. Actualmente, el PCNC incluye la detección de 24 enfermedades. Desde su inicio en el año 1969, se han cribado 2.787.807 recién nacidos, de los cuales 1.724 han sido diagnosticados de alguna de las 24 enfermedades que componen nuestro panel principal y 252 por diagnóstico diferencial de las primeras. En total la prevalencia global es de 1:1.617 RN afectos de alguna de las enfermedades incluidas en el PCNC y de 1:1.140 RN si se incluyen los hallazgos incidentales encontrados

The Catalonian Newborn Screening Program (CNSP) began in 1969, in Barcelona. It was promoted by Dr. Juan Sabater Tobella and supported by Barcelona Provincial Council and Juan March Foundation. That is how the Institute of Clinical Biochemistry was born, whose aims were diagnosis, research and teaching, along with the spirit of contributing to the prevention of mental retardation. The CNSP began with the detection of phenylketonuria (PKU), and, in 1982, the Program was expanded with the inclusion of congenital hypothyroidism detection. Towards 1990, the Program covered almost 100% of all newborns (NB) in Catalonia. In 1999, the CNSP was expanded with the incorporation of cystic fibrosis. It took fourteen years, until 2013, to make the largest expansion so far, with the incorporation of 19 metabolic diseases to the screening panel. The detection of sickle cell disease began in 2015 and in 2017 the detection of severe combined immunodeficiency was included. Currently, the CNSP includes 24 diseases in its main panel. Since 1969, 2,787,807 NBs have been screened, of whom 1,724 have been diagnosed with any of these diseases, and 252 of other disorders by differential diagnosis with those included in the main panel. The global prevalence is 1: 1,617 NBs affected by any of the diseases included in the CNSP and 1: 1,140 NBs if incidental findings diagnosed through the CNSP are included

Effectiveness of a brief primary care intervention to reduce passive smoking in babies: a cluster randomised clinical trial.

BACKGROUND: Tobacco smoke pollution (TSP) has major negative effects on infant health. Our objectives were to determine the effectiveness of a brief primary care intervention directed at parents who smoke in reducing babies' TSP exposure, and to establish variables related to greater exposure. METHOD: A multicentre, open, cluster-randomised clinical trial in Catalonia. The 83 participating primary health paediatric teams of the Catalan Health Service recruited 1101 babies whose parents were smokers. The intervention group (IG) received a brief TSP intervention; the control group (CG) received the usual care. Outcomes were measured by parents' reported strategies to avoid TSP exposure. Baseline clinical data and characteristics of each baby's TSP exposure were collected, along with infant hair samples and parents' tobacco use and related attitudes/behaviours. At 3-month and 6-month follow-up, behavioural changes to avoid TSP exposure were recorded; the association between reported parental behaviours and nicotine concentration in infant hair samples was tested in a random sample of 253 babies at baseline and 6 months. RESULTS: During follow-up, TSP-avoidance strategies improved more in the IG than in the CG: 35.4% and 26.9% ( p=0.006) at home, and 62.2% and 53.1% in cars (p=0.008). Logistic regression showed adjusted ORs for appropriate measures in the IG versus CG of 1.59 (95% CI 1.21 to 2.09) at home and 1.30 (95% CI 0.97 to 1.75) in cars. Hair samples showed that 78.7% of the babies tested were exposed. Reduced nicotine concentration was associated with improved implementation of effective strategies reported by parents at home (p=0.029) and in cars (p=0.014). CONCLUSIONS: The intervention produced behavioural changes to avoid TSP exposure in babies. The proportion of babies with nicotine (>=1ng/mg) in hair samples at baseline is a concern.

Mujeres y tabaco: aspectos principales específicos de género / Women and smoking: Gender-specifics principal aspects

El tabaquismo entre las mujeres representa un problema de salud pública muy importante. Su prevalencia ha ido aumentando en los últimos años tanto en los países desarrollados como en aquellos en vías de desarrollo. En nuestro país fuman actualmente un 27,2% de las mujeres mayores de 15 años y empiezan a observarse las consecuencias en relación a la mortalidad atribuible al tabaquismo. Son especialmente preocupantes las tasas de prevalencia observadas en jóvenes de 16 a 24 años, situándose en el caso de las mujeres en un 42,7%, 2 puntos por encima de los varones. El tabaquismo femenino presenta características diferenciales de género no sólo en el campo de la salud sino también en aquellos aspectos involucrados en la iniciación, el mantenimiento y el abandono del hábito tabáquico. En todo este proceso intervienen diversos factores históricos, socioculturales, psicológicos y ambientales. Estos últimos incluirían la creación y potenciación de un mercado femenino por parte de la industria tabaquera y el efecto que tienen las políticas fiscales en el consumo de tabaco femenino. Por todo ello, es necesario mantener e incrementar las estrategias tanto preventivas como dirigidas a la cesación del hábito tabáquico entre las mujeres (AU)

Smoking among women represents a very important public health problem. Smoking prevalence has been increasing recently not only in developed countries but especially among those less developed. In Spain, 27.2% of women older than 15 years old are smokers and consequences in tobacco attributable mortality are starting to be evident. Smoking prevalence among young people between 16 to 24 years old is of particular concern. Forty-seven point two percent of girls of this age are smokers, over two points above male prevalence. Female smoking shows several gender-specifics characteristics not only related to health but also among those factors intervening in initiation, maintenance and cessation of smoking. In all this process are included historical, sociocultural, psychological and environmental factors. The latter would relate to the setting up of a female market by the tobacco industry and to the effect of fiscal policies among female tobacco consumption. For all these, it is necessary to maintain and increase preventive and cessation strategies targeted to smoking habit among women (AU)
