RESUMEN
BACKGROUND: Mental health problems account for 14% of mortality worldwide. The aim of this study was to evaluate the association between psychological distress and mortality in the Spanish adult population. METHODS: Data came from a longitudinal study in population ≥15 years of age (n=21,005) who participated in the 2011-12 Spanish National Health Survey, which was linked to mortality records as of December 2020. Mental health was assessed with the GHQ-12, defining psychological distress as a dichotomous variable using a GHQ-12 score ≥3 as the cutoff point. Using Poisson regression, standardized mortality rate ratios (SRR) were estimated for all-cause, cardiovascular disease, and tumor-related mortality, adjusting for sociodemographic variables, lifestyles, and comorbidities. RESULTS: The standardized overall mortality rate in individuals with and without psychological distress was 14.58 and 10.90 per 1000 person-years, respectively, estimating an SRR of 1.34 (95%CI: 1.19-1.50). The SRR for tumor-related mortality was 1.17 (95%CI: 0.90-1.53), and cardiovascular-related mortality was related to higher distress (GHQ-12 ≥ 4): SRR of 1.22 (95%CI: 0.98-1.51). Among psychological distressed individuals, the overall mortality SRR for those with a previous mental disorder diagnosis was 1.18 (95%CI: 0.91-1.53) versus 1.34 (95%CI: 1.18-1.54) for those without such diagnosis (p for interaction=0.067). Similarly, distressed participants taking prescription drugs for mental disorders had a lower mortality risk than those not taking them (p for interaction=0.016). CONCLUSIONS: Individuals with psychological distress had a higher risk of overall-, cardiovascular disease- and tumor-related mortality. This association was higher among participants not previously diagnosed with a mental disorder and those not taking medication for mental issues.

PURPOSE: Regular light cigarette consumption (light smoking) is increasing in many countries; however, few studies have assessed its impact on mortality. The main aim of this study is to estimate the association between the number of cigarettes consumed and all-cause mortality in Spain while focusing on light smoking. METHODS: Longitudinal study based on data from 42,902 individuals aged ≥15 years included in the 2011-2012 (Spanish) National Health Survey or the 2014 European Health Survey for Spain. Data were linked with the mortality registry up to December 2020. Multivariate Cox regression models were used to estimate hazard ratios (HR) adjusted for sociodemographic variables, lifestyle factors, and health status indicators. RESULTS: Compared to never smokers, the mortality HR for nondaily smokers was 1.30 (95% CI: 0.81-2.09), increasing to 2.23 (95% CI: 1.25-3.96) among those smoking 1-2 cigarettes/d, and to 1.54 (95%CI: 1.14-2.07) for consumers of 3-5 cigarettes/day. When individuals who reported trying to quit during the previous year were excluded, resulting HRs were 1.31 (95% CI: 0.81-2.10), 1.48 (95% CI: 0.69-3.19) and 1.64 (95% CI: 1.16-2.34), respectively. CONCLUSIONS: Compared to never smokers, consumers of small quantities of tobacco, that is, light smoking, had an increased mortality risk. In view of these results, we suggest the need for awareness-raising campaigns regarding how smoking even a small number of cigarettes a day causes serious harm to one´s health.

â¢The literature reporting on rural-urban health status disparities remains inconclusive.â¢We analyzed data from a longitudinal population-based study using individual observations.â¢Our results show that the risks of all-cause and cancer mortality are greater in large cities than in other municipalities, with no clear urban-rural gradient.â¢Not differences were found among territories in cardiovascular mortality.
RESUMEN
The role of metals and metalloids beyond arsenic, copper, lead and cadmium in cardiovascular disease is not entirely clear. The aim of this study was to assess the association between 18 metal or metalloid levels in topsoil (upper soil horizon) with all-cause and specific cardiovascular mortality endpoints in Spain. We designed an ecological spatial study, to assess cardiovascular mortality in 7941 Spanish mainland towns from 2010 to 2014. The estimation of metals and metalloids concentration in topsoil came from the Geochemical Atlas of Spain from 13,317 soil samples. We also summarized the joint variability of the metals using principal components analysis (PCA). These components (PCs) were included in a Besag, York, and Mollié model to assess their association with cardiovascular mortality from all causes, coronary heart disease, cerebrovascular, hypertension, and conduction disorders. Our results showed, both in men and women, that at the lowest component scores range, PC2 (mainly reflecting Al, Be, Tl and U) was positively associated with coronary heart disease and cerebrovascular mortality. At medium/highest scores range, PC4 (mainly reflecting Hg) was positively associated with cerebrovascular mortality. For PC3 (reflecting Se), the association with coronary heart disease mortality was positive only in men at the highest PC scores range. For PC1 (partly reflecting metals such as Pb, As, Cu or Cd), we observed a strongly suggestive positive association with all-cause cardiovascular diseases mortality. Our ecological results are consistent with the available evidence supporting a cardiovascular role of excessive exposure to Se, Hg, Pb, As, Cu and Cd, but also identify Al, Be, Tl and U as potentially novel cardiovascular factors. Additional research is needed to confirm the biological relevance of our findings.

In 2014, the first case of secondary Ebola infection outside Africa detected in Spain, caused a sense of global threat. This study assess Risk Perception amongst the health personnel and identify the agents that amplified or reduced it. Through a snowball sampling, 5 in-depth interviews were carried out. Inclusion´s criteria: treating the patient suspected of Ebola and/or of having been actively involved in the management of the crisis. Triangulation and member checking were used to validate findings. Field work was between February and June 2015. In Risk Perception´s construction were involved Formation, Management of Information and Trust. Political and Health Authorities, Media and Unions acted as amplifiers whereas the Expert Committee and Hospital Management as reducers. Peer-to-peer behavior acted as a reducer amongst the medical staff and as an amplifier between the nursing and cleaning staff. This information would be relevant to better manage a health crisis of this characteristics.
En 2014, el primer caso de infección secundaria por ébola fuera de África detectado en España provocó una sensación de amenaza global. Este estudio evaluó la Percepción de Riesgo (PR) entre el personal de sanitario e identificó los agentes que la amplificaron o la redujeron. A través de un muestreo de bola de nieve, se realizaron 5 entrevistas en profundidad, siendo los criterios de inclusión: tratar al paciente con sospecha de ébola y/o haber participado activamente en el manejo de la crisis en el centro hospitalario. Se utilizó la triangulación para validar y verificación los resultados. El trabajo de campo se realizó entre febrero y junio de 2015. Los factores claves en la construcción de Percepción de Riesgo fueron la formación, la gestión de la información, el trato percibido por el personal sanitario y la confianza en las autoridades sanitarias. Las autoridades políticas y sanitarias, los medios de comunicación y los sindicatos actuaron como amplificadores de la PR, el Comité de Expertos y la Dirección del hospital lo hicieron como reductores de la PR. El comportamiento entre iguales actuó como reductor entre el personal médico y como amplificador entre el personal de enfermería y de limpieza. Se trata de información relevante de cara a manejar situaciones de crisis sanitarias de similares características.

Background: In recent years, abundant scientific evidence has been generated based on clinical trials (CT) in the field of oncology. The general objective of this paper is to find out the extent to which decision making is based on knowledge of the most recent CT. Its specific objectives are to pinpoint difficulties with decision making based on the CT performed and find out the motivations patients and clinicians have when taking part in a CT. Methodology: Combined, prospective study, based on the Delphi method. A lack of correspondence between the people who take part in CT and patients who come for consultation has been identified. A need for training in analysing and interpreting CT has also been identified and a lack of trust in the results of CT financed by the pharmaceutical industry itself has been perceived. Conclusions: There is a difficulty in selecting oncological treatment due to the lack of correspondence between the patients included in the CT and patients seen in consultation. In this process, real world data studies may be highly useful, as they may provide this group with greater training in interpreting CT and their results.
RESUMEN
It is likely that pollution from chemical facilities will affect the health of any exposed population; however, the majority of scientific evidence available has focused on occupational exposure rather than environmental. Consequently, this study assessed whether there could have been an excess of cancer-related mortality associated with environmental exposure to pollution from chemical installations - for populations residing in municipalities in the vicinity of chemical industries. To this end, we designed an ecological study which assessed municipal mortality due to 32 types of cancer in the period from 1999 to 2008. The exposure to pollution was estimated using distance from the facilities to the centroid of the municipality as a proxy for exposure. In order to assess any increased cancer mortality risk in municipalities potentially exposed to chemical facilities pollution (situated at a distance of ≤5 km from a chemical installation), we employed Bayesian Hierarchical Poisson Regression Models. This included two Bayesian inference methods: Integrated Nested Laplace Approximations (INLA) and Markov Chain Monte Carlo (MCMC, for validation). The reference category consisted of municipalities beyond the 5 km limit. We found higher mortality risk (relative risk, RR; estimated by INLA, 95% credible interval, 95%CrI) for both sexes for colorectal (RR, 1.09; 95%CrI, 1.05-1.15), gallbladder (1.14; 1.03-1.27), and ovarian cancers (1.10; 1.02-1.20) associated with organic chemical installations. Notably, pleural cancer (2.27; 1.49-3.41) in both sexes was related to fertilizer facilities. Associations were found for women, specifically for ovarian (1.11; 1.01-1.22) and breast cancers (1.06; 1.00-1.13) in the proximity of explosives/pyrotechnics installations; increased breast cancer mortality risk (1.10; 1.03-1.18) was associated with proximity to inorganic chemical installations. The results suggest that environmental exposure to pollutants from some types of chemical facilities may be associated with increased mortality from several different types of cancer.

We present the case of the Nahua population of Santa Rosa de Serjali, Peruvian Amazon's population, considered of initial contact. This population consists of human groups that for a long time decided to live in isolation, but lately have begun living a more sedentary lifestyle and in contact with Western populations. There are two fully identified initial contact groups in Peru: the Nahua and the Nanti. The health statistics of the Nahua are scarce. This study offers an interpretation of demographic and epidemiological indicators of the Nahua people, trying to identify if a certain degree of health vulnerability exists. We performed a cross sectional study, and after analyzing their health indicators, as well as the supplemental qualitative analysis of the population, brought us to conclude that in 2006, the Nahua, remained in a state of health vulnerability.

Resumen Presentamos el caso de la población Nahua de Santa Rosa de Serjali, una población de la región Amazonica del Perú, considerada en contacto inicial. Esta población está compuesta por grupos humanos que durante mucho tiempo han decidido vivir en aislamiento, pero últimamente han comenzado a vivir un estilo de vida más sedentario y en contacto con la población occidental. Hay dos grupos de contacto iniciales plenamente identificados en el Perú: Los Nahuas y los Nantis . Las estadísticas de salud de los nahuas son escasas. Este estudio ofrece una interpretación de los indicadores demográficos y epidemiológicos del pueblo Nahua, tratando de identificar si existe un cierto grado de vulnerabilidad de la salud . Se realizó un estudio transversal, y después de analizar sus indicadores de salud, así como el análisis cualitativo complementario de la población, nos llevó a la conclusión de que en el año 2006, los nahuas, aún presentaban un estado de vulnerabilidad en salud.
