Being born in winter-spring and at around the time of an influenza pandemic are risk factors for the development of schizophrenia: the apna study in Navarre, Spain
(MDPI, 2021) Álvarez-Mon, Miguel Ángel; Guillén Aguinaga, Sara; Pereira-Sánchez, Víctor; Onambele, Luc; Al-Rahamneh, Moad J.; Brugos Larumbe, Antonio; Guillén Grima, Francisco; Ortuño, Felipe; Ciencias de la Salud; Osasun Zientziak
Background: we analyzed the relationship between the prevalence of schizophrenia and the season of birth and gestation during a period of an influenza pandemic. Methods: cross-sectional analysis of a prospective population-based cohort of 470,942 adults. We fitted multivariant logistic regression models to determine whether the season of birth and birth in an influenza-pandemic year (1957, 1968, 1977) was associated with schizophrenia. Results: 2077 subjects had been diagnosed with schizophrenia. Logistic regression identified a significantly greater prevalence of schizophrenia in men than in women (OR = 1.516, CI 95% = 1.388–1.665); in those born in the winter or spring than in those born in the summer or autumn (OR = 1.112, CI 95% = 1.020–1.212); and in those born in a period of an influenza pandemic (OR = 1.335, CI 95% = 1.199–1.486). The increase in risk was also significant when each influenza pandemic year was analyzed separately. However, neither month of birth nor season of birth, when each of the four were studied individually, were associated with a statistically significant increase in that risk. Conclusions: the winter–spring period and the influenza pandemics are independent risk factors for developing schizophrenia. This study contradicts many previous studies and thus revitalizes a locked debate in understanding the neurodevelopmental hypothesis of this disorder.

Trends in mortality from stroke in Latin America and the Caribbean, 1979-2015
(Ubiquity Press, 2022) Soto Venegas, Álvaro; Guillén Grima, Francisco; Morales Illanes, Gladys; Muñoz, Sergio; Aguinaga Ontoso, Inés; Vanegas, Jairo; Ciencias de la Salud; Osasun Zientziak
Background: stroke is the second largest single cause of death and disability in Latin America and the Caribbean (LAC). There have been large overall declines in stroke mortality rates in most LAC countries in recent decades. Objective: to analyze trends in mortality caused by stroke in LAC countries in the period 1979-2015. Methods: we extracted data for age-standardized stroke mortality rates per 100,000 in LAC for the period 1979-2015 from the World Health Organization Mortality Database. Joinpoint regression was used to analyze the trends and compute the annual percent change (APC) in LAC as a whole and by country. Analyses were conducted by gender, region and World Bank income classification. Results: mortality from stroke has decreased in LAC over the study period by an average APC of -1.9%. Most countries showed significant downward trends, with the sharpest decreases in Chile, Colombia and Uruguay. We recorded statistically significant decreases of -1.4% and -2.4% in mortality rates in men and women, respectively, in the whole LAC. Southern and high-income countries showed the steepest decreases. Conclusions: stroke mortality has decreased in LAC, in both sexes, especially in southern and high-income countries. Our results could serve as a reference for the development of primary prevention and acute management of stroke policies focused on countries with higher mortality.

Illicit substance use among university students from seven European countries: a comparison of personal and perceived peer use and attitudes towards illicit substance use
(Elsevier, 2014) Helmer, Stefanie M.; Mikolajczyk, Rafael T.; McAlaney, John; Vriesacker, Bart; Guillén Grima, Francisco; Ciencias de la Salud; Osasun Zientziak
Objective: To compare European students' personal use and approval of illicit substance use with their perceptions of peer behaviours and attitudes, and investigate whether perceptions of peer norms are associated with personal use of illicit substances and attitudes. Method: This study used baseline data from the Social Norms Intervention for the prevention of Polydrug usE (SNIPE) project involving 4482 students from seven European countries in 2012. Students completed an online survey which included questions on personal and perceived peer illicit substance use and personal and perceived peer attitude towards illicit substances. Results: 8.3% of students reported having used illicit substances at least once in their life. 49.7% of students perceived that the majority of their peers have used illicit substances more frequently than themselves. The perception was significantly associated with higher odds for personal illicit substance use (OR: 1.97, 95% CI:1.53–2.54). The perception that the majority of peers approve illicit substance use was significantly associated with higher odds for personal approval of illicit substance use (OR: 3.47, 95% CI: 2.73–4.41). Conclusion: Students commonly perceived that their peers used illicit subtances more often than themselves. We found an association between the perceived peer norms/attitudes and reported individual behaviour/attitudes.

A feasibility trial to examine the social norms approach for the prevention and reduction of licit and illicit drug use in European University and college students
(BioMed Central, 2012) Pischke, Claudia R.; Zeeb, Hajo; Hal, Guido van; Vriesacker, Bart; McAlaney, John; Bewick, Bridgette M.; Akvardar, Yildiz; Guillén Grima, Francisco; Orosova, Olga; Salonna, Ferdinand; Kalina, Ondrej; Stock, Christiane; Helmer, Stefanie M.; Mikolajczyk, Rafael T.; Ciencias de la Salud; Osasun Zientziak
Background: Incorrect perceptions of high rates of peer alcohol and tobacco use are predictive of increased personal use in student populations. Correcting misperceptions by providing feedback has been shown to be an effective intervention for reducing licit drug use. It is currently unknown if social norms interventions are effective in preventing and reducing illicit drug use in European students. The purpose of this paper is to describe the design of a multi-site cluster controlled trial of a web-based social norms intervention aimed at reducing licit and preventing illicit drug use in European university students. Methods/Design: An online questionnaire to assess rates of drug use will be developed and translated based on existing social norms surveys. Students from sixteen universities in seven participating European countries will be invited to complete the questionnaire. Both intervention and control sites will be chosen by convenience. In each country, the intervention site will be the university that the local principal investigator is affiliated with. We aim to recruit 1000 students per site (baseline assessment). All participants will complete the online questionnaire at baseline. Baseline data will be used to develop social norms messages that will be included in a web-based intervention. The intervention group will receive individualized social norms feedback. The website will remain online during the following 5 months. After five months, a second survey will be conducted and effects of the intervention on social norms and drug use will be measured in comparison to the control site. Discussion: This project is the first cross-national European collaboration to investigate the feasibility of a social norms intervention to reduce licit and prevent illicit drug use among European university students. Final trial registration number DRKS00004375 on the ‘German Clinical Trials Register’.

Clinical impact of rapid bacterial microbiological identification with the MALDI-TOF MS
(MDPI, 2023) Uzuriaga, Miriam; Leiva, José; Guillén Grima, Francisco; Rua, Marta; Yuste, José R.; Ciencias de la Salud; Osasun Zientziak
Rapid microbiological reports to clinicians are related to improved clinical outcomes. We conducted a 3-year quasi-experimental design, specifically a pretest–posttest single group design in a university medical center, to evaluate the clinical impact of rapid microbiological identification information using MALDI-TOF MS on optimizing antibiotic prescription. A total of 363 consecutive hospitalized patients with bacterial infections were evaluated comparing a historical control group (CG) (n = 183), in which the microbiological information (bacterial identification and antibiotic susceptibility) was reported jointly to the clinician between 18:00 h and 22:00 h of the same day and a prospective intervention group (IG) (n = 180); the bacterial identification information was informed to the clinician as soon as it was available between 12:00 h and 14:00 h and the antibiotic susceptibility between 18:00 h and 22:00 h). We observed, in favor of IG, a statistically significant decrease in the information time (11.44 h CG vs. 4.48 h IG (p < 0.01)) from the detection of bacterial growth in the culture medium to the communication of identification. Consequently, the therapeutic optimization was improved by introducing new antibiotics in the 10–24 h time window (p = 0.05) and conversion to oral route (p = 0.01). Additionally, we observed a non-statistically significant decrease in inpatient mortality (global, p = 0.15; infection-related, p = 0.21) without impact on hospital length of stay. In conclusion, the rapid communication of microbiological identification to clinicians reduced reporting time and was associated with early optimization of antibiotic prescribing without worsening clinical outcomes.

Valoración de la repercusión del dolor sobre la productividad laboral: validación del cuestionario WPAI:Pain
(Gobierno de Navarra. Departamento de Salud, 2016) Varela, N.; Guillén Grima, Francisco; Pérez-Cajaraville, J. J.; Pérez Hernández, C.; Monedero, P.; Ciencias de la Salud; Osasun Zientziak
Fundamento. Los instrumentos de medida de salud son esenciales en la actividad clínica diaria. Sin embargo, es necesario un proceso de validación para poder certificar la validez y fiabilidad de los mismos. En la actualidad no existe ninguno que permita evaluar la repercusión del dolor en la productividad laboral de los pacientes. El objetivo de nuestro estudio es validar un cuestionario para evaluar las consecuencias del dolor en dicha productividad. Método. En base al Work Productivity and Activity Impairment Questionnaire – General Health hemos creado una versión modificada denominada WPAI: Pain con el fin obtener un cuestionario que pudiera medir las consecuencias del dolor en la productividad laboral. El estudio se realizó siguiendo las pautas habituales de validación de pruebas, omitiéndose las fases de redacción y validez de contenido ya que se modificaba un cuestionario existente. Resultados. Se obtuvieron 577 cuestionarios en dos hospitales universitarios españoles. Se comprobó la capacidad discriminante del cuestionario mediante prueba de U de Mann-Whitney. Se realizaron los test de fiabilidad obteniéndose un alfa de Cronbach de 0,896 con un test de dos mitades de Guttman de 0,921. Se comprobó la estabilidad con un test-retest estadísticamente significativo. La validez de constructo se estableció mediante correlación de Pearson comparando los resultados del cuestionario con el dolor en escala visual analógica, que resultó estadísticamente significativa para todos los valores. Conclusiones. El cuestionario WPAI: Pain es un instrumento de medida válido para determinar las consecuencias del dolor en la productividad laboral de los pacientes, siendo el único validado en español. Sin embargo, se requieren estudios de mayor envergadura para poder confirmar una validez universal.

Prevalencia de actividad física y su relación con variables sociodemográficas y estilos de vida en la población de 18 a 65 años de Pamplona
(Ministerio de Sanidad, Servicios Sociales e Igualdad, 2005) Elizondo Armendáriz, José Javier; Guillén Grima, Francisco; Aguinaga Ontoso, Inés; Ciencias de la Salud; Osasun Zientziak
Fundamento: los conocimientos actuales permiten considerar que existe una asociación de tipo causal entre el nivel de actividad física y la aparición de diversas enfermedades. A pesar de ello, la actividad física es una práctica poco arraigada en la población, que cada vez se está haciendo más sedentaria. El objetivo de este estudio es describir la prevalencia de sedentarismo en la población de Pamplona, así como conocer cuáles son los factores que más influyen en él. Métodos: se llevó a cabo un estudio transversal mediante encuesta postal en una muestra significativa de la población de Pamplona de 18 a 65 años. La encuesta utilizada incluía una evaluación de la actividad física realizada, basada en el cuestionario de actividad física de Paffenbarger. Se realizó un análisis bivariado y multivariado con aplicación de regresión logística. Resultados: un 76,6% de las mujeres tienen un estilo de vida sedentario, mientras que en los varones este porcentaje se reduce hasta un 56,7%. El sedentarismo se incrementa con la edad, existiendo hasta un 80,3% de varones sedentarios en el grupo de mayor edad, y un 86,3% entre las mujeres, respectivamente. Conclusiones: los factores sociodemográficos como sexo, edad, estudios, profesión y estado civil parecen ser determinantes del estilo de vida sedentario, mientras el consumo de tabaco y la existencia de sobrepeso y obesidad no lo son. Entre las personas jóvenes, las mujeres sin estudios universitarios y los varones casados y fumadores parecen ser poblaciones diana para la promoción de la actividad física.

(Arán Ediciones, 2015) Álvarez Álvarez, Ismael; Aguinaga Ontoso, Inés; Marín Fernández, Blanca; Guillén Grima, Francisco; Niu, Hao; Ciencias de la Salud; Osasun Zientziak
Introducción: La dieta mediterránea es un estilo de vida con efectos beneficiosos contrastados en el embarazo, tanto para la madre como para su descendencia. Sin embargo, se desconocen los factores que influyen en la adhesión a esta dieta. Objetivo: Investigar los factores (nivel educativo, ocupación, lugar de nacimiento, número de hijos previo y edad) que influyen en la adhesión a la dieta mediterránea en mujeres embarazadas de la comarca de Pamplona. Material y métodos: Utilizando los datos del Estudio Internacional de Sibilancias en Lactantes (EISL) en la comarca de Pamplona, se analizaron las asociaciones entre los alimentos y los factores. Se estableció una puntuación de dieta mediterránea y se estudiaron las puntuaciones de acuerdo a los factores. Resultados: Se encontraron diferencias significativas en la puntuación de dieta mediterránea según el nivel de estudios (p=<0,001), la ocupación (p=0,015) y la edad (p=<0,001). Conclusión: Mujeres con mejor nivel educativo, mejor ocupación y mayor edad muestran una mayor afinidad a la dieta mediterránea durante el embarazo.

Individual- and community-level determinants of maternal health service utilization in southern Ethiopia: a multilevel analysis
(SAGE, 2023) Yoseph, Amanuel; Teklesilasie, Wondwosen; Guillén Grima, Francisco; Astatkie, Ayalew; Ciencias de la Salud; Osasun Zientziak
Background: Maternal health service utilization decreases maternal morbidity and mortality. However, the existing evidence is inadequate to design effective intervention strategies in Ethiopia. Objectives: This study aimed to examine the utilization of maternal health service and identify its determinants among women of reproductive age in southern Ethiopia. Design: A community-based cross-sectional study was conducted from October 21 to November 11, 2022 on a sample of 1140 women selected randomly from the Northern Zone of the Sidama region. Methods: Data were collected using the Open Data Kit mobile application and exported to Stata version 15 for analysis. We used a multilevel mixed-effects modified Poisson regression with robust standard error to identify determinants of maternal health service utilization. Results: Utilization of antenatal care, health facility delivery, and postnatal care was 52.0% (95% confidence interval: 49.0%, 55.0%), 48.5% (95% confidence interval: 45.6%, 51.4%), and 26.0% (95% confidence interval: 23.0%, 29.0%), respectively. Antenatal care use was associated with receiving model family training (adjusted prevalence ratio: 1.19; 95% confidence interval: 1.06, 1.35), knowledge of antenatal care (adjusted prevalence ratio: 1.54; 95% confidence interval: 1.31, 1.81), perceived quality of antenatal care (adjusted prevalence ratio: 1.02; 95% confidence interval: 1.01, 1.03), and having birth preparedness plan (adjusted prevalence ratio: 1.13; 95% confidence interval: 1.02, 1.25). The identified determinants of health facility delivery use were middle wealth rank (adjusted prevalence ratio: 1.35; 95% confidence interval: 1.03, 1.77), perceived quality of health facility delivery (adjusted prevalence ratio: 1.02; 95% confidence interval: 1.01, 1.03), antenatal care (adjusted prevalence ratio: 1.76; 95% confidence interval: 1.36, 2.26), and high community-level women literacy (adjusted prevalence ratio: 1.55; 95% confidence interval: 1.10, 2.19). Postnatal care use was associated with facing health problems during postpartum period (adjusted prevalence ratio: 1.79; 95% confidence interval: 1.18, 2.72), urban residence (adjusted prevalence ratio: 3.52; 95% confidence interval: 2.15, 5.78), knowledge of postnatal care (adjusted prevalence ratio: 1.11; 95% confidence interval: 1.04, 1.19), and low community-level poverty (adjusted prevalence ratio: 0.43; 95% confidence interval: 0.25, 0.73). Conclusion: Maternal health service use was low in the study area and was influenced by individual- and community-level determinants. Any intervention strategies must consider multi-sectorial collaboration to address determinants at different levels. The programs should focus on the provision of model family training, the needs of women who have a poor perception, and knowledge of maternal health service at the individual level.

Evaluation of the degradation of materials by exposure to germicide UV-C light through colorimetry, tensile strength and surface microstructure analyses
(Elsevier, 2022) Mitxelena Iribarren, Oihane; Mondragón, Beñat; Pérez Lorenzo, Eva; Smerdou, Cristian; Guillén Grima, Francisco; Sierra-García, J. Enrique; Rodríguez Merino, Fernando; Arana, Sergio; Ciencias de la Salud; Osasun Zientziak
Due to the COVID19 pandemic, solutions to automate disinfection using UV-C combined with mobile robots are beginning to be explored. It has been proved that the use of these systems highly reduces the risk of contagion. However, its use in real applications is not being as rapid as it needs to be. One of the main market input barriers is the fear of degrading facilities. For this reason, it is crucial to perform a detailed study on the degradation effect of UV-C light on inert materials. This experimental study proves that, considering exposition times equivalent to several work years in hospital rooms, only the appearance of the material is affected, but not their mechanical functionalities. This relevant result could contribute to accelerate the deployment of these beneficial disinfection technologies. For that purpose, a colorimetry test, tensile strength test, and analysis of the surface microstructure were carried out. The results showed that polymers tend to turn yellow, while fabrics lose intensity depending on the color. Red is hardly affected by UV-C, but blue and green are. Thus, this study contributes to the identification of the best materials and colors to be used in rooms subjected to disinfection processes. In addition, it is shown how the surface microstructure of the materials is altered in most of the materials, but not the tensile strength of the fabrics.
