RESUMO
INTRODUCTION: Stroke mortality has declined in recent decades, but there appears to be a slowdown in the decline in recent years. We analyze the trends in stroke mortality in La Rioja (Spain) for the period 1999-2022. METHODS: We evaluated stroke mortality using statistical data from the mortality registry of La Rioja (Spain). We adjusted the rates by age and sex and analyzed both overall strokes and subtypes: hemorrhagic and ischemic. To analyze the trend in mortality rates we constructed joinpoint regression models, with associated annual percentage change (APC) RESULTS: Age-standardized stroke mortality declined between 1999 and 2022: females from 98.0 to 29.2 per 100 000; males, from 131.6 to 44.8 per 100 000. We found a decrease in overall stroke mortality in all age groups, except those under 65 years old. Ischemic stroke mortality showed declines in the first decade (APC: 7.3%, CI95%: 4.1-19.1%) and increases in the second decade (APC: 1.6%, CI95%: -1.6-11.7%) among men. In women, the rates declined between 2018 and 2022(APC: -6.6%, CI95%: -5.1-30.6%) after an increase between 2015 and 2017 (APC: 23.5%, CI95%: -20.2-38.3%). For hemorrhagic stroke, we found a consistent rate of decline throughout the entire time period in men (APC: 2.4%, CI95%: 0.9 a 4.0%). In women, rates increased during the period 1999-2009(APC: 1.9%, CI95%: -2.1-22.8%) and decreased 2010-2022 (APC: 6.5%, CI95%: 4.0-25.6%). CONCLUSIONS: Stroke mortality rates have decreased, more so for haemorrhagic than ischaemic strokes.
RESUMO
In the European Union, a rate of 11.9 cases per 100,000 was estimated in 2019.In Spain, suicide is the leading cause of external death. Social crises can have an impact on suicide rates. We analyzed changes in suicide mortality trends in Spain following the COVID-19 pandemic. We used statistical data from the National Institute of Statistics of Spain (1998-2021). We calculated age-specific rates, age and sex-adjusted rates, and analyzed trends and changes using joinpoint-regression models. Rates decrease in both sexes at the ages of 65 and older. In women, they increase in the ages of 1-29 years and 45-59 years. In men, they decrease in the ages of 15-39 years. Among women, age-adjusted rates remained stable between 1998 and 2021, with a non-significant annual decrease of 0.4 %. Among men, there was a significant annual decrease of 0.7 %. The years 2020 and 2021 had 8 % higher mortality compared to the two years prior to the COVID-19 pandemic. Suicide mortality in Spain slightly decreased among men and remained stable among women between 1998 and 2021, but there seems to be an increase following the COVID-19 pandemic.

OBJECTIVE: Sentinel surveillance is used to monitor health problems. The COVID detection strategy conducts universal surveillance of SARS-CoV-2 infection, which can be monitored by sentinel systems, through surveillance of mild acute respiratory infection (IRA) or severe respiratory infection (IRAG). The objective of this study was to compare incidence data obtained through sentinel surveillance against versus universal surveillance in acute respiratory infections. METHODS: A descriptive study of the incidences (cases/100,000 inhabitants) of acute respiratory infection (sudden onset of cough, sore throat, dyspnea or runny nose and clinical judgment of infection) was carried out in the entire population of La Rioja recorded in the primary care medical record, and in a sentinel cohort, by age and sex during the period from weeks 40-2021 to 06-2022. For SARI, the total number of hospitalized cases per 100,000 inhabitants with onset of symptoms in the previous ten days was calculated, as well as the incidence in a systematic selection of all SARI hospitalized one day a week. Weekly incidence rates were calculated in each cohort from week forty of 2021 to week six of 2022 by sex and age group. The characteristics of the population were expressed in their distribution by number and percentage. RESULTS: The data observed for ARI were similar in both systems by sex and age, except for the zero to four-year-old group and the group over seventy-nine years of age, where differences were observed, with the highest ARI figures in the first age group in sentinel surveillance, while in the older group they were superior in universal surveillance. SARIs showed a similar incidence, except in the fifteen/fourty-four age groups, which was higher in universal surveillance than in sentinel surveillance. CONCLUSIONS: There are no significant differences. Sentinel surveillance allows optimization of resources, being the most efficient methods for surveillance of high-incidence diseases.
OBJETIVO: La vigilancia centinela se emplea para monitorizar problemas de salud. En la Estrategia de detección de COVID se lleva a cabo vigilancia universal de infección por SARS-CoV-2, que puede pasar a monitorización mediante sistemas centinela, a través de vigilancia de infección respiratoria aguda leve (IRA) o grave (IRAG). El objetivo del presente trabajo fue comparar datos de incidencia obtenidos mediante vigilancia centinela frente a vigilancia universal en las infecciones respiratorias agudas. METODOS: Se realizó un estudio descriptivo de las incidencias (casos por cada 100.000 habitantes) de infección respiratoria aguda (comienzo súbito de tos, dolor de garganta, disnea o rinorrea y juicio clínico de infección) en toda la población de La Rioja, registrados en la historia clínica de Atención Primaria, y en una cohorte centinela, por edad y sexo durante el periodo que incluye la semana 40-2021 hasta la 06-2022. Para IRAG se calcularon los casos hospitalizados totales por cada 100.000 habitantes con inicio de síntomas en los diez días previos, así como la incidencia en una selección sistemática de todos los IRAG hospitalizados un día a la semana. Se calcularon las tasas de incidencia semanales en cada cohorte desde la semana cuarenta del año 2021 a la semana seis del año 2022 por sexo y grupo de edad. Las características de la población se expresaron en su distribución por número y porcentaje. RESULTADOS: Los datos observados para IRA fueron similares en ambos sistemas por sexo y edad, salvo para el grupo de cero a cuatro años y el de más de setenta y nueve años, donde se observaron diferencias, siendo las cifras de IRA más elevadas en el primer grupo de edad en la vigilancia centinela, mientras que en el grupo de mayores fueron superiores en la vigilancia universal. Las IRAG mostraron una incidencia similar, excepto en los grupos de edad de quince a cuarenta y cuatro años, que fue mayor en vigilancia universal que en el centinela. CONCLUSIONES: No se observan diferencias importantes. La vigilancia centinela permite optimización de recursos, siendo los métodos más eficientes para vigilancia de enfermedades de alta incidencia.

BACKGROUND: With the emergence of SARS-CoV-2, influenza surveillance systems in Spain were transformed into a new syndromic sentinel surveillance system. The Acute Respiratory Infection Surveillance System (SiVIRA in Spanish) is based on a sentinel network for acute respiratory infection (ARI) surveillance in primary care and a network of sentinel hospitals for severe ARI (SARI) surveillance in hospitals. METHODS: Using a test-negative design and data from SARI admissions notified to SiVIRA between January 1 and October 3, 2021, we estimated COVID-19 vaccine effectiveness (VE) against hospitalization, by age group, vaccine type, time since vaccination, and SARS-CoV-2 variant. RESULTS: VE was 89% (95% CI: 83-93) against COVID-19 hospitalization overall in persons aged 20 years and older. VE was higher for mRNA vaccines, and lower for those aged 80 years and older, with a decrease in protection beyond 3 months of completing vaccination, and a further decrease after 5 months. We found no differences between periods with circulation of Alpha or Delta SARS-CoV-2 variants, although variant-specific VE was slightly higher against Alpha. CONCLUSIONS: The SiVIRA sentinel hospital surveillance network in Spain was able to describe clinical and epidemiological characteristics of SARI hospitalizations and provide estimates of COVID-19 VE in the population under surveillance. Our estimates add to evidence of high effectiveness of mRNA vaccines against severe COVID-19 and waning of protection with time since vaccination in those aged 80 or older. No substantial differences were observed between SARS-CoV-2 variants (Alpha vs. Delta).

BACKGROUND. The aim of this study has been to analyze the development of pandemic influenza (H1N1) 2009 in La Rioja autonomous (cases in primary healthcare and cases hospitalized). METHODS. We have included all cases with 2009 H1N1 influenza from week 28-2009 to 3-2010. The main information was collected through Primary Healthcare databases (OMI), lists of Preventive Medicine Hospital Departments, reference laboratory and individual standardized forms. This information was analyzed and described according to week, sex, age, comorbidities, clinical development and medical complication. We explore the association of to antiviral treatment and risk factors. This association was assessed using odds ratios (OR) and 95% confidence interval (CI). Adjustment for confounders was performed using unconditional logistic regression to estimate the odds ratio (OR) and 95% confidence intervals (CI). RESULTS. From 29-2009 week to 3-2010 week, a total of 7096 pandemic influenza A(H1N1) cases were notified from Primary Healthcare and 111 laboratory confirmed severe cases were admitted to hospital. Five cases were admitted to an ICU (4,5%) and 2 cases died. All this patients had comorbidities. None of children and pregnant female were admitted to an ICU. CONCLUSIONS. Children and young person have been population with more cases of pandemic influenza (H1N1) 2009. Clinical evolution of pandemic in the majority cases in La Rioja, has been mild.

BACKGROUND: In Spain, influenza vaccine effectiveness (EV) is estimated since 2008-09 season through the cycEVA case-control study, the Spanish component of the European I-MOVE (Monitoring Influenza Vaccine Effectiveness in the EU/EEA) network. We aimed at describing cycEVA performance in its five consolidated editions 2008/09 -; 2012/13. METHODS: During the study period the following indicators were analysed: 1) the participation of sentinel general practitioners and pediatricians (MP), 2) the population studied and the study period, 3) the data quality and 4) the dissemination of the cycEVA results. Trend analysis of the indicators was done using the Cochran-Armitage test to compute the Annual Percentage Change (PCA). RESULTS: The number of participating MP increased from 164 in 2008-09 to 246 in the following editions. The percentage of MP recruiting at least one patient increased significantly annually (PCA = 15.33%). The percentage of recruited patients included into the analysis increased (PCA=5.91%) from 77% in 2008-09 to more than 95% in the following editions. The percentage of cycEVA patients contributing to the I-MOVE study ranged between 23% and 30% in the pilot and 2011-12 editions respectively.. Final results were disseminated in quartile 2 peer-reviewed journals and 2010-11 and 2011-12 preliminary EV estimates were published in quartile 1 journals. cycEVA publications received 97 citations. CONCLUSION: cycEVA study achieved more quality information, timely EV estimates and a higher impact of the results.

Fundamento: El objetivo de este estudio ha sido realizar un análisis de la evolución de la pandemia por el virus de la gripe (H1N1) 2009 en la Comunidad Autónoma de La Rioja tanto en atención primaria como en hospitalaria. Métodos: El periodo de estudio incluyó desde la semana 28-2009 hasta la 3-2010. La información de los casos de gripe se obtuvo de las bases informatizadas de atención primaria (OMI), de los listados remitidos por los servicios hospitalarios de medicina preventiva, del laboratorio de referencia de La Rioja y de los formularios de notificación individual. Se realizó una descripción de los casos según distribución por semana, sexo, edad, factores de riesgo, evolución y complicaciones. Se utilizó la regresión binaria logística para estimar las odds ratios ajustadas y su intervalo de confianza al 95%, de recibir tratamiento antiviral según factores de riesgo. Resultados: Hasta la semana epidemiológica 3 de 2010 se declararon a través del sistema OMI de atención primaria 7.096 casos de sospecha de gripe (H1N1) 2009, fueron hospitalizados 111 casos con diagnóstico confirmado por laboratorio. Requirieron atención en cuidados intensivos 5 (4,5%) y 2 fallecieron. Todos ellos presentaban factores de riesgo. Ninguno de los niños ni de las mujeres embarazadas hospitalizados precisaron ingreso en cuidados intensivos. Conclusiones: Durante la pandemia la gripe (H1N1) 2009 fue una enfermedad propia de la población pediátrica y joven, apareciendo con menor frecuencia en las personas mayores de 60 años. La evolución clínica en La Rioja cursó de forma leve en la mayoría de las personas diagnosticados(AU)
