Transmisión de la gripe en los servicios de urgencias

La mayoría de nosotros hemos experimentado alguna vez un déjà vu, sensación de reconocer una experiencia como si la hubiéramos vivido antes aunque sepamos que es la primera vez que la vivimos. Cada año, al finalizar el otoño, todos los profesionales sanitarios nos enfrentamos a un "déjà vu", que se puede resumir en pocas preguntas: ¿cómo será la gripe esta temporada?, ¿qué tan efectiva será la vacuna?, ¿aguantaremos la presión asistencial? En realidad, el déjà vu es un mecanismo que usa el cerebro para comprobar que nuestra memoria funciona perfectamente. Y con la gripe, funciona perfectamente

¿Por qué puede fallar una vacuna?

España registra desde hace unos años brotes de paperas más o menos frecuentes: uno de los últimos ha tenido lugar en Salamanca. Muchos de estos pacientes habían sido vacunados. ¿Por qué puede fallar una vacuna? La parotiditis (paperas) es una enfermedad infecciosa producida por un virus altamente transmisible. Se puede prevenir mediante una vacuna, que está incluida en la triple vírica junto a las del sarampión y la rubeola. En España se recomienda administrar dos dosis: al año y tres años de vida. La vacuna triple vírica se utiliza desde los años 1970 y se fabrica con virus atenuados. Para producirla se han empleado distintas cepas de virus (llamadas Jeryl Lynn, Uribe, Leningrado-Zagreb y Rubini)

El mundo mira hoy, con preocupación y temor, la evolución de la situación en China, donde a finales del año 2019 se registró un aumento de pacientes con infección respiratoria infectados por un nuevo coronavirus, identificado ahora con las siglas COVID-19, localizado en la ciudad de Wuhan

Percepciones de un grupo de inmigrantes sobre el Sistema Nacional de Salud y sus servicios

Objetivo: Conocer la percepción, la utilización y la satisfacción en relación con los servicios sanitarios de un grupo de inmigrantes residentes en Barcelona en relación con su género, procedencia y clase social. Diseno: ˜ Estudio descriptivo transversal. Emplazamiento: Ciudad de Barcelona, Espana. ˜ Participantes: Doscientos veinticinco inmigrantes usuarios de servicios sociosanitarios residentes en la ciudad de Barcelona, de junio a julio del 2012. Mediciones principales: Se analizaron el nivel de acceso y la relación de los inmigrantes residentes con el sistema sanitario público, a partir de una encuesta realizada en población inmigrante. Las respuestas obtenidas fueron analizadas en relación con los ejes: género, edad, clase social, salud autopercibida, país de origen, tiempo desde la llegada y estado civil. Resultados: El 89% de la población encuestada dijo «haber sido tratada con respeto» al acudir a los servicios de salud, siendo considerado este el aspecto más importante. Sin embargo, el 59,4% refirió una percepción de «discriminación hacia los inmigrantes» y el 68,4% manifestó que las diferencias culturales afectan «total o parcialmente» la calidad de la atención recibida. Para el 66,7% la atención sanitaria recibida en Barcelona es mejor que la recibida en su país de origen, principalmente por su calidad científico-técnica y por el acceso universal. Conclusiones: Pese a la buena valoración del sistema sanitario público universal este estudio mostró deficiencias del sistema en cuanto a los aspectos psicosociales de la atención sanitaria a inmigrantes en Barcelona. Es necesario profundizar en el estudio de los conocimientos y percepciones de colectivos minoritarios en el contexto actua

Monitoring the COVID-19 epidemic in the context of widespread local transmission.

Coronavirus disease 2019 (COVID-19) is a novel viral disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which was first detected in Wuhan, China, in December, 2019.1 Given the fast spread, the severity of disease, the increasing number of cases outside China, and the number of affected countries, WHO declared the rapid spread of SARS-CoV-2 a pandemic on March 11, 2020.2 The availability of reliable surveillance platforms is crucial to monitor the COVID-19 epidemic in a timely manner and to respond with adequate control measures. Since the beginning of the outbreak, different countries have used different testing approaches and criteria, depending on their resources and capacity

Highly infectious diseases in the Mediterranean Sea area: Inventory of isolation capabilities and recommendations for appropriate isolation.

Epidemics such as viral haemorrhagic fevers, severe acute respiratory syndrome, Middle East respiratory syndrome coronavirus or yet unknown ones have few chances of disappearing. Globalization, worldwide travel, climate change, social conflicts and wars, among others, are likely to favor the emergence of epidemics. Preparedness of hospitals to prevent the spread of these outbreaks is among the prioritized political programmes of many countries. The EuroNHID network has in the past drawn a map of features and equipment of hospitals across Europe to take care of highly contagious patients. We update the data regarding isolation capabilities and recommendations, with an emphasis on Mediterranean countries

Electric vehicle battery health expected at end of life in the upcoming years based on UK data

Second-life businesses from Electric Vehicle (EV) batteries are gaining attention considering that these batteries are deemed as inappropriate for transport purposes once they reach 80 or 70% of State of Health (SoH). However, the limited number of retired batteries and the trend in battery capacity increase hinder a realistic evaluation of second-life applications. To analyze battery reuse, a closer look at the End of Life (EoL) conditions of these batteries must be taken. This study presents a battery ageing model to estimate the SoH of EV batteries according to their age and mileage. The model is applied to the current retirement characteristics of combustion vehicles to statistically determine the expected SoH at the vehicle EoL. Results indicate that most EVs will reach EoL for reasons other than under-performance. Once retired, most EV batteries will have a SoH higher than 75% within the next 20 years, opening an interesting market for second-life businesses. However, battery reuse is an option that, considering the growing EV market, will rapidly saturate the stationary energy storage demand. Before 2040, most EV batteries will follow streams towards the circular economy, although at some point, they will have to be sent directly to recycling after the vehicular use.Peer ReviewedObjectius de Desenvolupament Sostenible::11 - Ciutats i Comunitats Sostenibles::11.2 - Per a 2030, proporcionar accés a sistemes de transport segurs, assequibles, accessi­bles i sostenibles per a totes les persones, i millorar la seguretat viària, en particular mitjan­çant l’ampliació del transport públic, amb especial atenció a les necessitats de les persones en situació vulnerable, dones, nenes, nens, persones amb discapacitat i persones gransObjectius de Desenvolupament Sostenible::11 - Ciutats i Comunitats SosteniblesPostprint (published version

Vaccination behaviour influences self-report of influenza vaccination status: a cross-sectional study among health care workers.

Background Published influenza vaccination coverage in health care workers (HCW) are calculated using two sources: self-report and vaccination records. The objective of this study was to determine whether self-report is a good proxy for recorded vaccination in HCW, as the degree of the relationship is not known, and whether vaccine behaviour influences self-reporting. Methods A cross-sectional study was conducted using a self-administered survey during September 2010. Considering the vaccination record as the gold standard of vaccination, the properties of self-report as a proxy of the record (sensitivity, specificity, positive predictive value, negative predictive value) were calculated. Concordance between the vaccination campaigns studied (2007-2010) was made using the Kappa index, and discordance was analyzed using McNemar's test. Results 248 HCW responded. The 95% confidence intervals of coverage according to the vaccination record and to self-report overlapped, except for 2007, and the Kappa index showed a substantial concordance, except for 2007. McNemar's test suggested that differences between discordant cases were not due to chance and it was found that the proportion of unvaccinated discordant cases was higher than that of vaccinated discordant cases. Conclusions In our study population, self-reported influenza vaccination coverage in HCW in the previous two years is a good proxy of the vaccination record. However, vaccination behaviour influences the self-report and explains a trend to overestimate coverage in self-reporting compared to the vaccination record. The sources of coverage should be taken into account whenever comparisons are made

Educating on professional habits: attitudes of medical students towards diverse strategies for promoting influenza vaccination and factors associated with the intention to get vaccinated

BACKGROUND: Influenza vaccination coverage in medical students is usually low. Unlike health care workers, there is little information on the attitudes to and predictors of vaccination among medical students, and their attitudes towards institutional strategies for improving rates are unknown. METHODS: This cross-sectional study evaluated the effect of three influenza vaccination promotional strategies (Web page, video and tri-fold brochure) on medical students’ intention to get vaccinated and associated factors. A total of 538 medical students were asked to answer an anonymous questionnaire assessing the intention to get vaccinated after exposure to any of the promotional strategies. Sociodemographic data collected included: sex, age, university year, influenza risk group and cohabiting with member of a risk group. RESULTS: Four hundred twenty-one students answered the questionnaire, of whom 312 (74.1%) were female, 113 (26.8%) had done clinical rotations, and 111 (26.6%) reported intention to get the flu shot. Logistic regression showed the web group had a greater intention to get vaccinated than the reference group (OR: 2.42 95% CI: 1.16-5.03). Having done clinical rotations (OR: 2.55 95% CI: 1.36-4.38) and having received the shot in previous flu seasons (OR: 13.69 95% CI: 7.86-23.96) were independently associated with the intention to get vaccinated. CONCLUSION: Given that previous vaccination is a factor associated with the intention to get vaccinated, education on vaccination of health care workers should begin while they are students, thereby potentiating the habit. In addition, the intention to get vaccinated was greater during the clinical phase of the university career, suggesting this is a good time to introduce promotion strategies. Online promotional campaigns, such as a thematic Web to promote vaccination of health workers, could improve the intention to get vaccinated
