Una vacuna pel virus de l'Ebola : un repte de desenvolupament i comunicació

L'Ebola es una malaltia transmissible, greu i sovint mortal. Els epidemiòlegs controlen les epidèmies d'ebola mitjançant mesures d'aïllament i seguiment de contactes. Quan el nombre de contagis és elevat una vacuna pot ser crucial en la disminució de la transmissió. La necessitat de disposar de vacunes enfront del virus de la ebola ha accelerat el desenvolupament experimental i els assajos clínics. En aquest article s'introdueix el virus de la ebola, s'exposen les fases de desenvolupament de vacunes i les peculiaritats de la comunicació en situacions d'emergència.Ebola disease is highly transmissible, serious and often deadly. Epidemiologists control Ebola epidemics by isolation measures and contact tracing. When the number of infections is high a new vaccine can be crucial in reducing transmission. The need for vaccines against Ebola virus has accelerated the experimental development and clinical trials. In this article we present Ebola virus, the phases of vaccine development and peculiarities of communication in emergency situations

Hesitation about coronavirus vaccines in healthcare professionals and general population in Spain

This study attempts to provide a picture of the hesitancy to vaccination against COVID-19 in Spain during the 2021 spring-autumn vaccination campaign, both in the general population and in healthcare professionals. The participants were recruited using social media such as Facebook and Twitter, in addition to the cooperation of health personnel contacted with the collaboration of medical scientific societies. A cross-sectional study was carried out that included the response of an online questionnaire. The data were collected from April 30 to September 26, 2021. To assess the different associations between variables to be measured, we fit Poisson regression models with robust variance. Responses were obtained from 3,850 adults from the general population group and 502 health professionals. Of the overall sample, 48.6% of participants from the general population were vaccinated against COVID-19, whereas in the healthcare professionals, 94.8% were vaccinated. The prevalence of general population vaccination increased with age, and was higher in women than men. Most participants did not show a preference for any vaccine itself. However, the prevalence of people vaccinated with their preferred vaccine was higher for the ones vaccinated with Pfizer's vaccine. 6.5% of the general population reported being reticent to be vaccinated. People from younger age groups, people with lower educational levels and those who were not from a risk group showed greater reluctance to be vaccinated. No gender differences in reluctancy were found. Health professionals were significantly less likely to refuse vaccination even though they had more doubts about the safety and efficacy of vaccines. On the other hand, younger people, those with a lower level of education and those who were not from a risk group were the most hesitant

Regional differences in the profile of disabled community-dwelling older adults: a European population-based cross-sectional study

The main objective of this work was to estimate the prevalence of disability in European community-dwelling older adults, as well as to investigate differences in the profile of disabled older adults between European regions (Northern, Central, Eastern and Southern). A cross-sectional study based on wave 6 (2015) of the Survey of Health, Ageing and Retirement in Europe (SHARE) was conducted. Community-dwelling participants aged 65-84 were selected (n = 33,369). Disability was defined as presenting at least one functional limitation in basic activities of daily living (BADL). Sociodemographic, health services, lifestyle and health-related variables were analyzed. Statistical analysis was carried out through the Chi-square and ANOVA tests for bivariate analysis, and Poisson regression for multivariate analysis. Overall prevalence of disability was 13.8%: 9.4% in the Northern region, 13.1% in the Southern region, 13.6% in the Central region, and 16.6% in the Eastern region. Portugal, Poland, Estonia and Belgium showed the highest prevalence of BADL limitations, while Sweden, Denmark, Greece and Switzerland showed the lowest prevalence. Besides, disabled older adults from East Europe presented the most disadvantaged health profile, followed by the Southern region. On the other hand, disabled older adults living in the Northern region showed the most advantaged characteristics of most variables, except for smoking and polypharmacy

Methods: We analyzed data from waves 4, 5 and 6 of the Survey of Health Ageing and Retirement in Europe (SHARE). We estimated age-standardized hazardous drinking prevalence, and prevalence ratios (PR) of hazardous drinking by country and educational level using Poisson regression models with robust variance. We estimated the relative index of inequality (RII) for all-cause mortality among hazardous drinkers and non-hazardous drinkers using Cox proportional hazards regression models and for each region (North, South, East and West). Results: In men, educational inequalities in hazardous drinking were not observed (PRmedium = 1.09 [95%CI: 0.98-1.21] and PRhigh = 0.99 [95%CI: 0.88-1.10], ref. low), while in they were observed in women, having the highest hazardous drinking prevalence in the highest educational levels (PRmedium = 1.28 [95%CI: 1.15-1.42] and PRhigh = 1.53 [95%CI: 1.36 1.72]). Overall, the Relative Index of Inequality (RII) in all-cause mortality among hazardous drinkers was 1.12 [95%CI: 1.03-1.22] among men and 1.10 [95%CI: 0.97-1.25] among women. Educational inequalities among hazardous drinkers were observed in Eastern Europe for both men (RIIhazardous = 1.21 [95%CI: 1.01-1.45]) and women (RIIhazardous = 1.46 [95%CI: 1.13-1.87]). Educational inequalities in mortality among non-hazardous drinkers were observed in Southern, Western and Eastern Europe among men, and in Eastern Europe among women. Conclusions: Higher educational attainment is positively associated with hazardous drinking prevalence among women, but not among men in most of the analyzed European countries. Clear educational inequalities in mortality among hazardous drinkers were only observed in Eastern Europe. Further research on the associations between alcohol use and inequalities in all-cause mortality in different regions is needed

Consumption of Alcohol, Cannabis, and Tobacco in a Cohort of Adolescents before and during COVID-19 Confinement

The aim of this study was to identify changes in the hazardous consumption of alcohol, tobacco, and cannabis, due to the COVID-19 lockdown in 2020 in a cohort of schooled adolescents from Central Catalonia. We also analyzed the effect of the individual and social factors on risky consumption during confinement. This longitudinal study involved a subsample of 303 adolescents aged 14-18 years, who were attending 4th year of compulsory secondary education (ESO), 2nd year of college preparation (baccalaureate), or Vocational and Educational Training (VET). We collected data before COVID-19 lockdown (October 2019-February 2020) and 2 months after the lockdown ended. We estimated the prevalence of risky substance use in the sample at baseline for each independent variable. We used Poisson regression models with robust variance to compute the Cumulative Incidence (CI) and Relative Risk (RR), with their respective 95% confidence interval. We found that VET students had a significantly (p < 0.05) higher risk of substance use: binge drinking (RR = 3.21 (95%CI: 1.00-10.34)); hazardous drinking of alcohol (RR = 3.75 (95%CI: 1.12-12.54)), hazardous consumption of cannabis (RR = 3.75 (95%CI: 0.65-21.59)) and daily smoking of tobacco (RR = 4.82 (95%CI: 1.74-13.39)). The results showed a general trend of reduction of consumption during COVID-19 confinement period. This study suggests that VET students were more likely to engage in hazardous drinking of alcohol and daily smoking of tobacco. No statistically significant differences were found for the other age groups and variables

Assessing the association between tourism and the alcohol urban environment in Barcelona: a cross-sectional study

Objectives: Alcohol availability and promotion are not distributed equally in the urban context. Evidence shows that the socioeconomic level seems to influence the amount of alcohol-related elements in an area. Some studies suggest that tourism could also affect the distribution of these elements. We explore with a valid instrument in a large city whether there is an association between high tourism pressure and a greater presence of alcohol-related elements in the urban environment. Design: Observational ecological study. Setting: The study was conducted in Barcelona during 2017-2018. Participants: We assessed urban exposure to alcohol by performing social systematic observation using the OHCITIES Instrument in a stratified random sample of 170 census tracts within the city's 73 neighbourhoods. Primary and secondary outcome measures: For each census tract we calculated the density of alcohol premises, and of promotion in public places per 1000 residents. We estimated tourism pressure using the number of tourist beds per 1000 residents in each neighbourhood and calculated quartiles. To assess the relationship between rate ratios of elements of alcohol urban environment and tourism pressure, we calculated Spearman correlations and fitted Poisson regression models with robust error variance. Results: The median densities obtained were of 8.18 alcohol premises and of 7.59 alcohol advertising and promotion elements visible from the public space per 1000 population. Census tracts with the highest tourism pressure had 2.5 (95% CI: 1.85-3.38) times more outlets and 2.3 (95% CI: 1.64-3.23) times more promotion elements per 1000 residents than those in the lowest tourism pressure quartile. Conclusions: We observed a strong association between tourism pressure and alcohol exposure in the city of Barcelona

Understanding how alcohol environment influences youth drinking: A concept mapping study among university students

The aim of the study was to identify the environmental factors that influence alcohol consumption, according to university students, and assess the relative importance and the frequency attributed to each factor. A study using Concept Mapping methodology was performed with a sample of nursing students, who participated in two face-to-face data collection sessions. In session 1, a consensus about the environmental aspects that influence their alcohol consumption was obtained. In session 2, the statements obtained were rated according to their relative importance and frequency in alcohol use (1 = minimum; 5 = maximum). Subsequently, all data were analyzed with the RCMAP of the statistical package R 3.6.1. Approximately 60 students participated in each session. Most were women aged 20 to 24. In session 1, a total of 55 statements were obtained and classified into 7 different clusters: Advertising (9 statements); Family environment (4 statements); Social pressure (12 statements); Responsibilities/ norms (4 statements); Holidays and leisure time (7 statements); Emotional situations (8 statements); Accessibility (11 statements). Factors related to social pressure, holidays and leisure time, and alcohol accessibility were considered the most important and frequent in alcohol consumption. In contrast, alcohol advertising was considered the least important (mean 2.6 out of 5) and frequent (mean 2.1 out 5) factor. In conclusion, the factors considered most relevant among nursing students match those having more resources allocated for prevention and health promotion, except for alcohol advertising, which was perceived as less important and frequent compared with the other factors

Changes in perceptions of the alcohol environment among participants in a Photovoice project conducted in two districts with different socio-economic status

Perceptions of the alcohol environment may influence alcohol consumption patterns. The purpose of this study was to describe changes in perceptions of the urban alcohol environment as experienced by residents of two districts with different socio-economic status after taking part in a Photovoice study. The study was conducted in Madrid, Spain, in a district with a high socio-economic status (HSES) and another district with a low socio-economic status (LSES). A Photovoice project was conducted with 26 participants divided into four groups based on sex and district. Groups met over five sessions in which they discussed photographs taken by the participants themselves on the subject of alcohol in their neighbourhood. A qualitative, descriptive and thematic analysis of participants' discourses was performed to explore changes in their perceptions of the alcohol environment over the project sessions. Changes in perceptions of the alcohol environment were observed in all groups over the project. The process of change varied by districts' socio-economic characteristics and gender. Greater changes in perceptions of the alcohol environment were observed in HSES, especially among women, as the participants had a much more positive initial view of their alcohol environment. In LSES, participants showed a more critical perception of the alcohol environment from the beginning of the study, and this broadened and intensified over the course of the sessions. Changes in perceptions also varied by thematic categories, including some categories that were discussed from the start (e.g. socialising and alcohol consumption) and categories that only emerged in later sessions (e.g. alcohol advertising). Involvement in a Photovoice project has favoured a shift in the participant's perceptions of their alcohol environment towards more critical positions, widening their scope of perceived elements and raising their awareness of specific problems, such as alcohol advertising and social role of alcohol consumption in relation to alcohol exposure

Residents perceptions of the alcohol environment: A participatory photovoice project in two districts with different socio-economic status in a large city

The purpose of this study was to present the alcohol environment as perceived by its residents in two districts of Madrid using the Photovoice participatory methodology. Secondly, we compared the results according to the socio-economic status of the districts. The study was conducted in the city of Madrid, Spain, in two districts with different socio-economic status. A total of 26 people participated, who took and discussed photographs about their alcohol environment. They grouped them into 33 final categories, such as the socialising role of alcohol or the alcohol advertising. Co-authors further grouped participants final categories into seven general areas. The participants in the Photovoice project have helped to deepen the understanding of the alcohol urban environment. These results may help to design more effective policies to prevent hazardous alcohol consumption.This work was supported by the Plan Nacional sobre Drogas, Spain [grant numbers 2016I047]; The HeartHealthy Hoods project was funded by the European Research Council under the European Union’s Seventh Framework Programme, European Union [FP7/2007–2013/ERC Starting Grant Heart Healthy Hoods Agreement no. 623 336893]; and IM received a research fellowship from the University of Alcala, Spain that enables her to develop this study.
