    Background The relationship between tobacco and depressive symptoms has been examined. However, there is little information on the evolution of these symptoms when an individual quits. The aim of this study was to analyze the evolution of depressive symptoms over time (pre-, post-treatment, 1-, 3-, 6-, and 12-months follow-up) in relation to smoking status 12 months after having received a psychological treatment for smoking cessation. Method The sample was made up of 242 adults who received cognitive-behavioral treatment for smoking cessation (64.4% women; mean age=41.71 years). The BDI-II was used to assess depressive symptomatology. Participants were classified into three groups according to smoking status at 12-months follow-up (abstainers, relapsers, and smokers). Results There were no significant differences in depressive symptoms among the three groups at pretreatment. At the end of treatment, abstainers and relapsers presented less depressive symptomatology than smokers. At follow-up, abstainers continued to present less depressive symptomatology than smokers, whereas in relapsers, symptoms began to increase as the relapses occurred. Regarding the evolution of depressive symptomatology, the abstainer and relapser groups showed a significant reduction at the end of treatment. Only in the group of abstainers did the decrease continue during 12 months follow-up. Limitations The decrease of the initial sample size from 562 to 242 participants. Variables such as self-esteem and self-efficacy were not assessed. Conclusions Smoking cessation is associated with a decrease in depressive symptomatology, that is maintained over time. In contrast, relapse is associated with an increase of such symptoms. These findings signify the potential importance of addressing depressive symptomatology in smoking cessation treatment

    Diverse studies have found a relation between alcohol consumption and smoking relapse. Few studies have analyzed the relation of smoking relapse with pretreatment alcohol consumption and gender differences. The main purpose of this study is to analyze the influence of alcohol consumption in smoking relapse over 12 months (3-, 6-, and 12-months follow-up) and to determine possible gender differences. The sample included 374 smokers who quit smoking by participating in a psychological smoking cessation treatment. We assessed hazardous pretreatment alcohol drinking (AUDIT), cigarette consumption (FTND; number of cigarettes) and sociodemographic variables. Higher scores on hazardous pretreatment alcohol drinking predict smoking relapse at 3-, 6-, and 12-months after smoking cessation. In males, higher scores on hazardous pretreatment alcohol drinking predict relapse at 6 and at 12 months. In females, higher scores on hazardous pretreatment alcohol drinking predict tobacco relapse at 3 months. Hazardous pretreatment alcohol drinking predicts relapse at all intervals after smoking cessation (3-, 6-, and 12-months follow-up). However, the influence of hazardous pretreatment alcohol drinking on smoking relapse differs as a function of gender, as it is a short-term predictor in women (3 months) and a long-term predictor in men (6 and 12 months)

    Background: Previous studies have shown that smoking is associated with health-related quality of life (HRQoL) impairment. In order to evaluate HRQoL in a sample of Spanish relapsers, a cross-sectional study was conducted. Method: The sample was made up of 775 smokers who had relapsed after a period of abstinence. HRQoL was evaluated using the Euro-Qol questionnaire (EQ-5D); through the descriptive profile, the EQ-5D index and the visual analogue scale (EQ-VAS). Results: Higher nicotine dependence was related to worse HRQL. According to the EQ-VAS, higher daily cigarette consumption and more years smoking were related to worse perceived health. In the EQ-5D those who had quit smoking in the previous year perceived worse health. Mobility and anxiety/ depression are the dimensions affected by smoking. Those who are more nicotine dependent (OR = 2.29) and have been smoking for longer (OR = 4.12) are more likely to have mobility problems; and those who are nicotine dependent (OR = 1.85) and relapsed more than a year ago (OR = 0.63), are more likely to experience anxiety/ depression. Conclusions: Nicotine dependence demonstrated a determining effect on HRQOL deterioration in smokers who have relapsed

    Producción CientíficaPurpose: To develop a tear molecule level-based predictive model based on a panel of tear cytokines and their correlation with clinical features in ocular chronic graft versus host disease (cGVHD). Methods: Twenty-two ocular cGVHD patients and 21 healthy subjects were evaluated in a controlled environmental research laboratory (CERLab). Clinical parameters were recorded, and tears were collected. Levels of 15 molecules (epidermal growth factor [EGF], IL receptor antagonist [IL-1Ra], IL-1β, IL-2, IL-6, IL-8/CXCL8, IL-10, IL-12p70, IL-17A, interferon inducible protein [IP]-10/CXCL10, IFN-γ, VEGF, TNF-α, eotaxin 1, and regulated on activation normal T cell expressed and secreted [RANTES]) were measured by multiplex-bead assay and correlated with clinical parameters. Logistic regression was used to develop a predictive model. Leave-one-out cross-validation was applied. Classification capacity was evaluated in a cohort of individuals with dry eye (DE) of other etiologies different from GVHD. Results: Epidermal growth factor and IP-10/CXCL10 levels were significantly decreased in ocular cGVHD, positively correlating with tear production and stability and negatively correlating with symptoms, hyperemia, and vital staining. Interleukin-1Ra, IL-8/CXCL8, and IL-10 were significantly increased in ocular cGVHD, and the first two correlated positively with symptoms, hyperemia, and ocular surface integrity while negatively correlating with tear production and stability. Predictive models were generated, and the best panel was based on IL-8/CXCL8 and IP-10/CXCL10 tear levels along with age and sex, with an area under the receiving operating curve of 0.9004, sensitivity of 86.36%, and specificity of 95.24%. Conclusions: A predictive model based on tear levels of IL-8/CXCL8 and IP-10/CXCL10 resulted in optimal sensitivity and specificity. These results add further knowledge to the search for potential biomarkers in this devastating ocular inflammatory disease.Ministry of Economy and Competitiveness, Madrid, Spain, SAF-2010 15631 (AES)

    Smoking relapse situations among a community-recruited sample of Spanish daily smokers

    Get PDF
    Introduction Relapse is a common factor within the behavior change process. However, there is scarce and limited knowledge of smoking relapse situations in population-based samples. The aim of this study was to identify smoking relapse situations among a sample of Spanish relapsers from the general population. Methods A sample of 775 relapsers was recruited among the general population using a snowball method. Participants completed a survey including sociodemographic, smoking-related and psychopathology variables. Smoking relapse situations were identified through specific questions assessing different aspects related to the last relapse episode. Results The majority of smoking relapse situations were attributed to positive affect (36.6%) and negative affect (34.3%), followed by lack of control (10.1%), smoking habit (6.7%), craving or nicotine withdrawal (6.3%), and social pressure (5.9%). Being unemployed and having a mental disorder in the past increased the likelihood of relapse in situations of negative affect. Being single and having quit smoking to save money were associated with an increased likelihood of relapse in situations of positive affect. Conclusions Affect plays a significant role in smoking relapse among a community sample of unassisted Spanish smokers. Relapse may be much more of an affective and situational process than a habit, physiological or social pressure. Findings from this study may help develop tailored community smoking relapse prevention strategies or programs

    Pedigree analyses of two endangered cattle breeds were performed in order to study the structure and the genetic variability in their populations. Pedigree data were analyzed from 12,057 individuals belonging to the “Berrenda en Negro” cattle breed (BN) and 20,389 individuals belonging to the “Berrenda en Colorado” cattle breed (BC) that were born between 1983 and 2020. BN and BC reference populations (RP) were set up by 2300 and 3988 animals, respectively. The generation interval in BN and BC reference populations was equal to 6.50 and 6.92 years, respectively. The pedigree completeness level was 82.76% in BN and 79.57% in BC. The inbreeding rates were 4.5% in BN and 3.4% in BC, respectively. The relationship among animals when they were born in different herds was 1.8% in BN and 5% in BC; these values increased to 8.5% and 7.7%, respectively when comparing animals that were born in the same herd. The effective number of founding herds was 23.9 in BN and 60.9 in BC. Number of ancestors needed to explain 50% of genes pool in the whole population was 50 and 101, in BN and in BC, respectively. The effective population size based on co-ancestries was 92.28 in BN and 169.92 in BC. The genetic variability has been maintained in both populations over time and the results of this study suggest that measures to promote the conservation of the genetic variability in these two breeds would go through for the exchange of breeding animals among farms and for monitoring the genetic contributions before implementing any selective action

    Cognitive-behavioral treatment with behavioral activation for smokers with depressive symptomatology: Study protocol of a randomized controlled trial

    Get PDF
    Background: Smoking is an important risk factor for mental health-related problems. Numerous studies have supported a bi-directional association between cigarette smoking and depression. Despite the advances in understanding the comorbidity between both problems, the most effective psychological treatment that simultaneously targets smoking and depressive symptomatology remains unclear. The objective of this study is to assess the effectiveness of a cognitive-behavioral intervention for smoking cessation with components of behavioral activation for managing depressed mood. Method: A single blind, three-arm, superiority randomized controlled trial is proposed. Participants will be smokers over 18years old, who smoke at least 8 cigarettes per day. Participants will be randomized to one of three conditions, using a 2:2:1 allocation ratio: 1) standard cognitive-behavioral smoking cessation treatment; 2) standard cognitive-behavioral smoking cessation treatment plus behavioral activation; or 3) a three-month delayed treatment control group. The primary outcome measures will be biochemically verified point-prevalence abstinence (carbon monoxide in expired air) and significant change from baseline in depressive symptoms to the end of treatment, and at the 3-, 6-, and 12-month follow-up. Discussion: This study aims to assess the efficacy of a cognitive-behavioral intervention with behavioral activation components for smoking cessation and depressive symptoms, compared to a standard cognitive-behavioral intervention to quit smoking. As the relation between depressive symptoms, even at subclinical levels, and quitting smoking difficulties is well known, we expect that such intervention will allow obtaining higher abstinence rates, lower relapse rates, and mood improvement. Trial registration:ClinicalTrials.gov: NCT02844595. Retrospectively registered 19th July, 2016. The study started in January 2016, and the recruitment is ongoing

    Intra-university mediation on the road to the sustainable development goals: a systematic review

    Get PDF
    Mediation as a formula for resolving conflicts is becoming increasingly relevant internationally as a mechanism for a peaceful conflict resolution. In Europe, many countries are enacting legal regulations, and European directives promote the use of mediation to resolve disputes between individuals, companies, institutions, etc. Mediation has a wide range of possibilities in terms of fields of action: family, judicial, school, community, etc. One of those becoming increasingly relevant is intra-university mediation, as a mechanism for resolving conflicts between the people/agents involved, among the students themselves and their peers. Moreover, mediation is related to education and the culture of peace, which are critical aspects of a more autonomous and independent society that can solve conflicts. Bearing in mind the possibilities provided by mediation and as a horizon for intra-university mediation, we propose a systematic review that pivots on three axes: a) conflict and mediation as a means to resolve dissent; b) intra-university mediation, experiences, and possibilities; c) intra-university mediation and its relationship with the Sustainable Development Goals. To do so, a systematic review has been carried out in scientific databases using a qualitative methodologyin order to identify the role of mediation in the university environment and the benefits that the university community and society can obtain. Among the main findings is the evidence that educational mediation at the university level is viable and is widely developed internationally

    Brotes de transmisión alimentaria asociados al consumo de leche cruda. España 2002-2012

    Get PDF
    En el año 2013, según los datos de consumo en hogares del Ministerio de Agricultura, Alimentación y Medio Ambiente, en España se consumió un total de 42 toneladas de leche cruda (1,2% del total de leche líquida). Actualmente sólo la certificación de calidad de leche cruda está autorizada para la venta al consumidor final, ya que el resto de leche cruda debe sufrir previamente un tratamiento térmico si va destinada al mismo. La leche cruda se define como un producto producido por una o varias vacas, que no haya sido calentado a una temperatura superior a 40ºC ni sometido a un tratamiento de efecto equivalente1 . La leche cruda tiene diversos microorganismos. Éstos pueden ser beneficiosos como Lactococcus sp. o Streptococcus sp. que facilitan la elaboración de ciertos alimentos a partir de la leche; o como Lactobacillus sp. y Bifidobacterium sp. que promueven la salud de las personas. Los microorganismos también pueden ser perjudiciales por deteriorar el alimento (Pseudomonas sp., Clostridium sp., Bacillus sp., entre otros) o por causar enfermedades (Listeria sp., Salmonella sp., Escherichia coli, Campylobacter sp. y micotoxinas)2.Los brotes ocurridos en cualquier ámbito y debidos a cualquier agente se notifican a la Red Nacional de Vigilancia Epidemiológica (RENAVE) según el Real Decreto 2210/1995. En los brotes de transmisión alimentaria notificados a la RENAVE se especifica el alimento o vehículo implicado, incluyendo la leche y sus derivados. En el 2004 se publica el Real Decreto 217/2004, por el que se regulan la identificación y registro de los agentes, establecimientos y contenedores del sector lácteo, dando lugar al sistema de información LETRA Q (leche cruda de vaca, trazabilidad y calidad). Se produjo una modificación en 2007, con el Real Decreto 1728/2007, por el que se establece la normativa básica de control, añadiendo el módulo de calidad al sistema LETRA Q. En concordancia a estos cambios legislativos, el consumo de leche cruda en España disminuyó notablemente en el año 2006 hasta que en 2009 se estabilizó3. La Autoridad Europea de Seguridad Alimentaria (EFSA) creó un grupo de trabajo perteneciente al panel científico de riesgos biológicos encargado de los riesgos de salud pública relacionados con el consumo de leche cruda, cuya última reunión se llevó a cabo en mayo de 2014. Consecuencia de la misma, se está recabando información de los Estados Miembros sobre los brotes asociados a leche cruda. En la base de datos de la RENAVE no existe ninguna variable que indique específicamente si la leche es cruda o no. Los informes de brotes alimentarios publicados por EFSA señalan que en Europa se han producido ocho brotes asociados a leche cruda desde el año 2008, destacando los años 2011 y 2012 con tres brotes cada uno4–8. El objetivo de este informe es analizar los brotes de transmisión alimentaria asociados a leche cruda en España durante el periodo 2002-2012N
