    Introducción: La enfermedad de Alzheimer es el principal tipo de demencia, y una enfermedad de etiología desconocida. Con el aumento de la población anciana mundial, el número de pacientes con enfermedad de Alzheimer muestra una tendencia de crecimiento rápido. El objetivo de este metaanálisis es evaluar la prevalencia e incidencia de la enfermedad de Alzheimer en Europa. Metodología: La búsqueda de artículos se realizó en las bases de datos Medline, Scopus y CINAHL Complete utilizando las palabras claves “Alzheimer”, “Alzheimer’s disease” y “AD”; combinadas con “prevalence”, “incidence” y “epidemiology”. Se utilizó el modelo Bayesiano de efectos aleatorios, mostrando intervalos de credibilidad al 95%. Para estimar la heterogeneidad se usó el estadístico I2. Resultados: La prevalencia de enfermedad de Alzheimer en Europa fue 5,05% (IC 95% 4,73-5,39). La prevalencia por sexo en los hombres y las mujeres fue 3,31% (IC 95% 2,85-3,80) y 7,13% (IC 95% 6,56-7,72), respectivamente, y se encontró una tendencia creciente por grupos de edad. La incidencia de enfermedad de Alzheimer en Europa fue 11,08 por 1000 personas-año (IC 95% 10,30-11,89), siendo en los hombres y las mujeres de 7,02 por 1000 personas-año (IC 95% 6,06-8,05) y 13,25 por 1000 personas-año (IC 95% 12,05-14,51), respectivamente, con igual tendencia creciente con el aumento de la edad. Conclusiones: Los resultados del metaanálisis permiten una mejor comprensión de la enfermedad y su impacto en Europa.

    Variability in the control of type 2 diabetes in primary care and its association with hospital admissions for vascular events. The APNA study
    (MDPI, 2021) Guillén Aguinaga, Sara; Forga, Lluís; Brugos Larumbe, Antonio; Guillén Grima, Francisco; Guillén Aguinaga, Laura; Aguinaga Ontoso, Inés; Ciencias de la Salud; Osasun Zientziak
    Type 2 diabetes (T2D) is associated with increased cardiovascular morbidity, mortality, and hospital admissions. This study aimed to analyze how the differences in delivered care (variability of glycosylated hemoglobin (HbA1c) achieved targets) affect hospital admissions for cardiovascular events (CVEs) in T2D patients. Methods: We analyzed the electronic records in primary care health centers at Navarra (Spain) and hospital admission for CVEs. We followed 26,435 patients with T2D from 2012 to 2016. The variables collected were age, sex, health center, general practitioner practice (GPP), and income. The clinical variables were diagnosis of T2D, weight, height, body mass index (BMI), blood pressure (BP), HbA1c, low-density lipoprotein cholesterol (LDL-C), smoking, and antecedents of CVEs. We calculated, in each GPP practice, the proportion of patients with HbA1c ≥ 9. A non-hierarchical K-means cluster analysis classified GPPs into two clusters according to the level of compliance with HbA1C ≥ 9% control indicators. We used logistic and Cox regressions. Results: T2D patients had a higher probability of admission for CVEs when they belonged to a GPP in the worst control cluster of HbA1C ≥ 9% (HR = 1.151; 95% CI, 1.032–1.284).

    (Elsevier España, 2019) Onambele, Luc; San Martín Rodríguez, Leticia; Niu, Hao; Álvarez Álvarez, Ismael; Arnedo Pena, Alberto; Guillén Grima, Francisco; Aguinaga Ontoso, Inés; Ciencias de la Salud; Osasun Zientziak
    Introducción: La mortalidad infantil es un indicador de la salud infantil y una variable explicativa del desarrollo socioeconómico. Nuestro objetivo fue examinar los cambios y tendencias de la mortalidad infantil en la Unión Europea (UE) y sus 28 países miembros en el período 1994-2015. Métodos: Se recopilaron datos de muertes de niños menores de un año entre 1994 y 2015 de la base de datos Eurostat. Estudiamos las tendencias en la UE, por países y regiones, utilizando elanálisis de regresión joinpoint. Se condujeron análisis adicionales para estudiar las tendencias de mortalidad neonatal y neonatal precoz. Resultados: La mortalidad infantil en la UE ha disminuido significativamente de 8.3 a 3.6 por 1.000 (porcentaje de cambio anual = −3.8%, intervalos de confianza del 95% −4.1; −3.6). Las tasas de mortalidad más altas se registraron en Rumanía y Bulgaria, y las tasas más bajas en países escandinavos (Finlandia, Suecia). Se encontraron tendencias descendentes significativas en los países de la UE, más pronunciadas en los países bálticos exsoviéticos y países de Europa oriental, mientras que los países de Europa occidental mostraron los descensos menos pronunciados. La mortalidad infantil ha aumentado significativamente en Grecia en los últimos años,mientras que en el Reino Unido e Irlanda las tasas se han estabilizado. Conclusiones: La mortalidad infantil ha disminuido en la UE y sus países en las últimas décadas, más pronunciadamente en los países de Europa oriental y los países bálticos exsoviéticos, mientras que en varios países de Europa occidental las tasas aumentaron o se han estabilizado enlos últimos años.

    Meta-analysis of prevalence of wheezing and recurrent wheezing in infants
    (Elsevier, 2016) Álvarez Álvarez, Ismael; Niu, Hao; Guillén Grima, Francisco; Aguinaga Ontoso, Inés; Ciencias de la Salud; Osasun Zientziak
    Background: Wheezing affects children’s quality of life, and is related with asthma in childhood. Although prevalence of wheezing has been previously studied in several countries, there are no reference of worldwide prevalence in infants. The aim of this meta-analysis is to estimate the prevalence of wheezing and recurrent wheezing in infants aged up to two years, and compare the prevalence across world regions. Methods: Literature search was conducted in MEDLINE and SCOPUS databases, looking for observational studies published up to June 2016, including as keywords “prevalence” or “epidemiology” combined with “wheeze”, “wheezing” or “asthma symptoms” and “infant” or “preschool”. Fast*Pro software and random effects Bayesian model were used. Heterogeneity was estimated using I2 statistic, and sensitivity analyses were performed. Results: We identified 109 studies after duplicates were removed. After exclusions, 14 studies were included in the meta-analysis. Prevalence of wheezing and recurrent wheezing were 36.06% (95% CI 35.17-36.96), and 17.41% (95% CI 16.74-18.09), respectively. In European countries, prevalence of wheezing was 30.68% (95% CI 28.97-32.45), and 12.35% (95% CI 11.27-13.47) for recurrent wheezing. Prevalence of wheezing and recurrent wheezing in Latin America were higher, 40.55% (95% CI 39.40-41.71), and 19.27% (95% CI 18.44-20.11), respectively. In Africa, prevalence of wheezing was 15.97% (95% CI 14.05-18.00). Low or no heterogeneity was found in all cases. Conclusions: More than one third of infants suffer from wheezing and almost one fifth from recurrent wheezing, being these illnesses especially prevalent in Latin American countries, pointing out an important public health problem.

    Prevalence and time trends of symptoms of allergic rhinitis and rhinoconjunctivitis in spanish children: Global Asthma Network (GAN) study
    (Codon Publications, 2023) Bercedo Sanz, Alberto; Martínez-Torres, Antonela; López Silvarrey Varela, Ángel; Pellegrini Belinchón, Francisco Javier; Aguinaga Ontoso, Inés; González Díaz, Carlos; García Marcos, Luís; Ciencias de la Salud; Osasun Zientziak
    INTRODUCTION: The time trends of the prevalence of rhinitis, rhinoconjunctivitis and nasal allergy previously described in the ISAAC (International Study of Asthma and Allergies in Childhood) in 2002 are unknown; or if the geographical or age differences in Spain persist. OBJECTIVE: To describe the prevalence of rhinitis, rhinoconjunctivitis and nasal allergy in different Spanish geographical areas and compare them with those of the ISAAC. METHODS: Cross-sectional study of the prevalence of rhinitis, rhinoconjunctivitis and nasal allergy, carried out in 2016-2019 on 19943 adolescents aged 13-14 years and 17215 schoolchildren aged 6-7 years from six Spanish areas (Cartagena, Bilbao, Cantabria, La Coruña, Pamplona, and Salamanca), through a questionnaire based on the Global Asthma Network (GAN) protocol. RESULTS: The prevalences of recent rhinitis and rhinoconjunctivitis (last 12 months), and nasal allergy/hay fever were 35.1%, 17.6%, and 14.6% in the adolescents and 20%, 8.5%, and 8.9% in the schoolchildren, respectively, with rhinoconjunctivitis in adolescents varying from 20.9% in Bilbao to 13.4% in Cartagena; and in schoolchildren, from 9.8% in La Coruña to 6.4% in Pamplona. These prevalences of rhinoconjunctivitis and nasal allergy in adolescents were higher than those described in the ISAAC (16.3% and 13%) and similar in schoolchildren to the ISAAC (9% and 9.4%). CONCLUSIONS: There has been a stabilisation of rhinitis, rhinoconjunctivitis and nasal allergy in schoolchildren that slows the previous upward trend of ISAAC; and a slight non-significant increase in rhinoconjunctivitis and nasal allergy in adolescents. The variability found in adolescents would require local research to be better understood.

    (MDPI, 2025-12-24) Aguinaga Ontoso, Inés; Guillén Aguinaga, Sara; Guillén Aguinaga, Laura; Alas Brun, Rosa María; Guillén-Aguinaga, Miriam; Onambele, Luc; Aguinaga Ontoso, Enrique; Rayón Valpuesta, Esperanza; Guillén Grima, Francisco; Ciencias de la Salud; Osasun Zientziak
    Background: The COVID-19 pandemic disrupted routine child immunization efforts, threatening to reverse progress in controlling vaccine-preventable diseases. Materials and Methods: We analyzed the impact of COVID-19 on DTP3 vaccination in Europe by comparing trends before and after the pandemic using time series data from 2000 to 2023. Employing joinpoint regression, chi-square tests, and segmented regression analysis, we assessed DTP3 vaccination trends and coverage changes. Results: The findings revealed significant regional disparities across Europe. Statistical models indicated reductions in DTP3 coverage in countries such as Ireland, Sweden, and Switzerland, whereas Ukraine and San Marino showed improvements. Conclusions: There are variations in the effect of COVID-19 on DTP3 coverage rates, indicating the need for targeted public health strategies to address vaccine hesitancy, logistical barriers, and systemic inequities.

    (Ministerio de Sanidad, Consumo y Bienestar Social, 2016) Orzanco Garralda, María Rosario; Guillén Grima, Francisco; Sáinz Suberviola, María Lourdes; Redín Areta, María Dolores; Rosa Eduardo, Rosanna de la; Aguinaga Ontoso, Inés; Ciencias de la Salud; Osasun Zientziak
    Fundamentos: Un entorno adecuado puede favorecer la práctica de la actividad física, siendo una opción fácil para la población. El objetivo fue determinar la influencia de la percepción de los factores urbanísticos ambientales en el nivel de actividad física de las personas adultas. Métodos: Estudio transversal basado en el International Physical Activity and the Environment Network. Las personas participantes fueron seleccionadas de forma aleatoria y estratificada de la población de las zonas básicas de salud del Área Metropolitana de Pamplona entre las que tenían edad de 18 a 65 años. Se utilizó un cuestionario autoadministrado que incluyó la versión completa de la escala Neighborhood Environment Walkability Scale para valorar la percepción de los factores urbanísticos ambientales y la versión larga del International Physical Activity Questionnaire para recoger datos de actividad física. Se calculó la chi2 y se realizó un análisis multivariable mediante regresión logística no condicional Resultados: Participaron 905 sujetos (54,70% mujeres). Tener sendas de paseo próximas al domicilio o lugar de trabajo se relacionó con practicar actividad física moderada OR: 3,86 (IC 95% 1,70-8,74)] y actividad física total (suma de actividad física vigorosa, moderada y caminar) OR: 2,61 (IC 95% 1,24-5,45)]. La presencia en el barrio de lugares a los que podían ir caminando se asoció con dedicar más tiempo a caminar [OR: 1,26 (IC 95% 1,01-1,58)] y disponer cerca del domicilio o lugar de trabajo de espacios deportivos se asoció conpracticar más actividad física vigorosa [OR: 1,46 (IC 95% 1,01 - 2,12). Conclusiones: Existe asociación directa entre las personas que se declaran más activas y los factores urbanísticos ambientales, como sendas de paseo o instalaciones deportivas.

    (SAGE, 2018) Niu, Hao; Álvarez Álvarez, Ismael; Aguinaga Ontoso, Inés; Guillén Grima, Francisco; Ciencias de la Salud; Osasun Zientziak
    Background: Alzheimer’s disease (AD) has become a concerning public health issue. We aimed to analyse the trends of hospital morbidity from AD in the European Union (EU) in the period 2000-2014. Methods: Data from hospital discharges of men and women over 50 years old hospitalised from AD in the EU were extracted from Eurostat database. We tested for secular trends computing the annual percent change, and identifying significant changes in the linear slope of the trend. Results: Hospital morbidity from AD showed a 0.8% (95% confidence intervals -2.2, 0.6) slight declining trend in the EU. In men and women, we recorded a -0.5% and -1.0% decrease in hospital morbidity rates, respectively. Several countries showed changing trends during the study period. Conclusion: AD hospital morbidity has slightly declined in the entire EU in the past years. Eastern European countries showed steadily increasing trends, whereas in western and Mediterranean countries rates decreased or levelled off.

    Evaluating the efficacy of ChatGPT in navigating the spanish medical residency entrance examination (MIR): promising horizons for AI in clinical medicine
    (MDPI, 2023) Guillén Grima, Francisco; Guillén Aguinaga, Sara; Guillén Aguinaga, Laura; Alas Brun, Rosa María; Onambele, Luc; Ortega-Leon, Wilfrido; Montejo, Rocío; Aguinaga Ontoso, Enrique; Barach, Paul; Aguinaga Ontoso, Inés; Ciencias de la Salud; Osasun Zientziak
    The rapid progress in artificial intelligence, machine learning, and natural language processing has led to increasingly sophisticated large language models (LLMs) for use in healthcare. This study assesses the performance of two LLMs, the GPT-3.5 and GPT-4 models, in passing the MIR medical examination for access to medical specialist training in Spain. Our objectives included gauging the model’s overall performance, analyzing discrepancies across different medical specialties, discerning between theoretical and practical questions, estimating error proportions, and assessing the hypothetical severity of errors committed by a physician. Material and methods: We studied the 2022 Spanish MIR examination results after excluding those questions requiring image evaluations or having acknowledged errors. The remaining 182 questions were presented to the LLM GPT-4 and GPT-3.5 in Spanish and English. Logistic regression models analyzed the relationships between question length, sequence, and performance. We also analyzed the 23 questions with images, using GPT-4’s new image analysis capability. Results: GPT-4 outperformed GPT-3.5, scoring 86.81% in Spanish (p < 0.001). English translations had a slightly enhanced performance. GPT-4 scored 26.1% of the questions with images in English. The results were worse when the questions were in Spanish, 13.0%, although the differences were not statistically significant (p = 0.250). Among medical specialties, GPT-4 achieved a 100% correct response rate in several areas, and the Pharmacology, Critical Care, and Infectious Diseases specialties showed lower performance. The error analysis revealed that while a 13.2% error rate existed, the gravest categories, such as “error requiring intervention to sustain life” and “error resulting in death”, had a 0% rate. Conclusions: GPT-4 performs robustly on the Spanish MIR examination, with varying capabilities to discriminate knowledge across specialties. While the model’s high success rate is commendable, understanding the error severity is critical, especially when considering AI’s potential role in real-world medical practice and its implications for patient safety.

    Maternal mortality in Africa: regional trends (2000-2017)
    (MDPI, 2022) Onambele, Luc; Ortega-Leon, Wilfrido; Guillén Aguinaga, Sara; Forjaz, Maria Joao; Yoseph, Amanuel; Guillén Aguinaga, Laura; Alas Brun, Rosa María; Arnedo Pena, Alberto; Aguinaga Ontoso, Inés; Guillén Grima, Francisco; Ciencias de la Salud; Osasun Zientziak
    Background: United Nations Sustainable Development Goals state that by 2030, the global maternal mortality rate (MMR) should be lower than 70 per 100,000 live births. MMR is still one of Africa’s leading causes of death among women. The leading causes of maternal mortality in Africa are hemorrhage and eclampsia. This research aims to study regional trends in maternal mortality (MM) in Africa. Methods: We extracted data for maternal mortality rates per 100,000 births from the United Nations Children’s Fund (UNICEF) databank from 2000 to 2017, 2017 being the last date available. Joinpoint regression was used to study the trends and estimate the annual percent change (APC). Results: Maternal mortality has decreased in Africa over the study period by an average APC of −3.0% (95% CI −2.9; −3,2%). All regions showed significant downward trends, with the greatest decreases in the South. Only the North African region is close to the United Nations’ sustainable development goals for Maternal mortality. The remaining Sub-Saharan African regions are still far from achieving the goals. Conclusions: Maternal mortality has decreased in Africa, especially in the South African region. The only region close to the United Nations’ target is the North African region. The remaining Sub-Saharan African regions are still far from achieving the goals. The West African region needs more extraordinary efforts to achieve the goals of the United Nations. Policies should ensure that all pregnant women have antenatal visits and give birth in a health facility staffed by specialized personnel.
