RESUMEN

Toxoplasmosis is one of the most common parasitic zoonoses and represents a significant health risk for humans, especially for immunodeficient patients. The main transmission route is by oral uptake of oocysts and consumption of undercooked meat of infected animals. Different species have been evaluated as possible reservoirs of the parasite, but few studies have been carried out to examine the role of horses in transmission of the disease. Given the proximity of these animals to humans and the widespread consumption of their meat in many countries, including the Mediterranean basin, it is important to determine the prevalence of T. gondii infection in this species. In this study, blood samples from 105 horses were collected and the presence of T. gondii was evaluated by serological and molecular methods. Antibodies against T. gondii of 12 horses (11.43%) were detected by enzyme-linked immunosorbent assay (ELISA), whereas 29 horses (27.62%) showed positive for PCR. Seroprevalence was related to use of the animals, being higher in horses used for dressage than in others. Purebreds had higher seroprevalence than crossbred animals. No differences between breed, sex or age were found. The results of this study confirm the presence of T. gondii infection in horses, highlighting the need to analyse the meat of this species before human consumption and to control of this infection in horses, as they could be an important reservoir of this zoonotic parasite.

RESUMEN

OBJECTIVE: To study factors associated with hospitalization in an unselected population of patients aged 65 years or older treated for syncope in Spanish hospital emergency departments (EDs). To determine the prevalence of adverse events at 30 days in patients discharged home and the factors associated with such events. METHODS: We included all patients aged 65 years or older who were diagnosed with syncope during a single week in 52 Spanish EDs, recording patient clinical and ED case management data. We compared the findings between hospitalized patients and those discharged home, following the latter for 30 days. In discharged patients, we explored predictors of a composite adverse-event outcome (occurrence of any of the following: ED revisits, hospitalization related to the index visit, or any-cause death). RESULTS: A total of 477 patients with syncope were identified; 67 (14%) were admitted, and 5 (7.5%) died. The median (interquartile range) length of hospital stay was 6 days (3-11 days). Comorbidity increased the probability of hospitalization (odds ratio, 2.172; 95% CI, 1.013-4.655). Among the 410 patients (86%) discharged home from the ED, 9.2% experienced an adverse event within 30 days (ED revisits, 8.,1%; hospitalization, 2.2%; death, 1.5%). No factors were associated with the 30-day composite outcome. CONCLUSIONS: The majority of patients aged 65 years or older are discharged home from EDs, and 30-day adverse events, while infrequent, are difficult to predict. Hospitalization was related to comorbidity and an absence of cognitive decline.

OBJETIVO: Investigar en una muestra no seleccionada de población mayor (65 o más años) atendida en servicios de urgencias hospitalarios (SUH) españoles por síncope los factores que se asociaron con la hospitalización, prevalencia de eventos adversos (EA) a 30 días y los factores asociados a estos entre los pacientes dados de alta desde urgencias. METODO: Se incluyeron todos pacientes con 65 o más años diagnosticados de síncope durante una semana en 52 SUH españoles. Se recogieron datos de la situación clínica y el manejo en urgencias, que se compararon entre los pacientes hospitalizados y los dados de alta directamente desde urgencias. Estos últimos fueron seguidos durante 30 días y se identificaron aquellos que presentaron un EA combinado (reconsulta en urgencias u hospitalización relacionada con el evento índice y muerte por cualquier causa), y se investigaron los factores que predecían dicho EA combinado. RESULTADOS: Se identificaron 477 pacientes con síncope. Hospitalizaron 67 (14%), de los que fallecieron 5 (7,5%) y la estancia mediana fue de 6 días (RIC 3-11). La comorbilidad incrementó la probabilidad de ingreso (OR: 2,172, IC 95%: 1,013-4,655). Entre los 410 pacientes dados de alta de urgencias (86%), el 9,2% tuvo un EA durante los 30 días siguientes (reconsulta a urgencias: 8,1%; hospitalización: 2,2%; muerte: 1,5%). Ningún factor se asoció con el riesgo de EA combinado a 30 días. CONCLUSIONES: La mayoría de los pacientes con 65 años o más atendidos en los SUH por síncope son dados de alta directamente desde urgencias, y los EA a los 30 días fueron poco frecuentes, pero difíciles de predecir. La hospitalización se relacionó con presencia de comorbilidad y ausencia de deterioro cognitivo.

RESUMEN

OBJECTIVE: To estimate the prevalence of inappropriate use of prophylaxis to prevent venous thromboembolism (VTE) in patients with medical diseases admitted to hospital from the emergency department. To explore variables associated with inappropriate thromboprophylaxis. METHODS: Prospective multicenter cohort study in 15 hospital emergency departments. We included patients admitted for a medical condition during 7 days in the first quarter of 2022. We assessed risk for VTE with the Padua Prediction Score (PPS). Inappropriate thromboprophylaxis was defined by failure to prescribe prophylaxis in patients with a high-risk PPS assessment unless there were absolute contraindications (active bleeding or severe thrombopenia) or, alternatively, the prescription of prophylaxis in patients with a low-risk PPS assessment or absolute contraindications. A logistic regression model was adjusted for risk level to identify variables associated with inappropriate use of thromboprophylaxis. RESULTS: Of a total of 630 patients included, 450 (71.4%) had PPS scores indicating high risk for VTE; 180 patients were at low risk. Thromboprophylaxis was inappropriate in 248 patients (39.4%): 165 high-risk patients who received no prophylaxis, 82 low-risk patients who were nonetheless treated, and 1 patient who was treated in spite of severe thrombopenia. Odds ratios (ORs) revealed that the variables associated with inappropriate use of thromboprophylaxis were trauma or recent surgery (OR, 5.53; 95% CI, 1.58-19.34), presence of factors indicating risk for bleeding (OR, 2.61; 95% CI, 1.44-4.73), and hospital admission for either urinary tract infection (OR, 2.29; 95% CI, 1.07-4.87) or gastrointestinal disease (OR, 4.30; 95% CI, 1.71-10.85). CONCLUSIONS: The inappropriate use of thromboprophylaxis in Spanish emergency departments is high and associated with certain clinical characteristics.

OBJETIVO: Evaluar la inadecuación de la tromboprofilaxis farmacológica, según la escala Padua (PPS), para prevenir la enfermedad tromboembólica venosa (ETV) entre los pacientes que ingresan desde el servicio de urgencias hospitalario (SUH) por patología médica, así como las variables asociadas a su uso inadecuado. METODO: Estudio de cohortes, prospectivo, multicéntrico donde participaron 15 SUH. Se incluyeron los pacientes atendidos que requirieron ingreso por enfermedad médica durante 7 días del primer trimestre de 2022. La inadecuación de la tromboprofilaxis farmacológica se definió como la no utilización en pacientes clasificados por PPS de alto riesgo sin contraindicaciones absolutas para su uso (hemorragia activa o trombopenia grave) o su utilización en pacientes de riesgo bajo o con contraindicaciones absolutas. Se ajustó, para cada grupo de riesgo, un modelo de regresión logística para identificar las variables asociadas a la inadecuación. RESULTADOS: Se incluyeron 630 pacientes, 450 (71,4%) tenían riesgo alto y 180 (28,6%) riesgo bajo para ETV según la PPS. De ellos, la tromboprofilaxis fue inadecuada en 248 pacientes (39,4%) (165 tenían riesgo alto pero no recibieron tromboprofilaxis, 1 la recibió teniendo trombopenia grave y 82 tenían riesgo bajo pero recibieron tromboprofilaxis). Las variables asociadas con la inadecuación en pacientes de alto riesgo fueron trauma o cirugía recientes con odds ratio (OR) de OR 5,53 (IC 95%: 1,58-19,34), presencia de factores de riesgo hemorrágico con OR de 2,61 (IC 95%: 1,44-4,73), e infección del tracto urinario con OR de 2,29 (IC 95%: 1,07-4,87) y enfermedad gastrointestinal con OR de 4,30 (IC 95%: 1,71-10,85) como motivos de ingreso. CONCLUSIONES: En los SUH españoles, el uso inadecuado de la tromboprofilaxis farmacológica es elevado. Algunas características clínicas se asocian al uso inadecuado de dicha tromboprofilaxis.

RESUMEN

OBJECTIVE: To determine survival to discharge and neurological outcomes on long-term follow-up of pediatric patients attended for out of-hospital cardiac arrest (OHCA). METHODS: Retrospective study based on an ongoing OHCA registry. Patients aged 16 years or younger were included. Futile resuscitation attempts were excluded. Neurological outcome on hospital discharge and on follow-up was based on variables in the Pediatric Cerebral Performance Category (PCPC) scale. Cases from January 1, 2008, through December 31, 2019, were extracted, and 2 surveys were carried out in May 2021 and January 2023. Patient follow-up time ranged from 1 to 13 years. RESULTS: Of the 13 778 patients in the registry, we found 277 (2.0%) who were aged 16 years or younger. One hundred thirty-seven patients (49.5%) were transported to a hospital, and spontaneous circulation was restored in 99 (35.7%). Thirty-six patients (13%) were discharged. The median (interquartile range) follow-up time was 2172 (978-3035) days. Thirty-one of these patients (86.1%) were alive at follow-up, 3 had died, and 2 were lost to follow-up. Neurological outcomes had worsened in 2 and improved in 6 patients. The neurological outcome of 27 of the 31 patients with complete follow-up data (87.1%) was good (PCPC scores of 1 or 2). CONCLUSIONS: In spite of the low incidence of shockable rhythm in pediatric OHCA, survival with a good neurological outcome is comparable to survival in adults. Children who are discharged after OHCA maintained or improved their neurological function over the long term.

OBJETIVO: Conocer la supervivencia al alta y la evolución neurológica tras seguimiento a largo plazo de pacientes pediátricos atendidos por parada cardíaca extrahospitalaria. METODO: Estudio retrospectivo basado en un registro continuo de parada cardiaca extrahospitalaria. Se incluyeron los pacientes pediátricos (edad menor o igual a 16 años). Se excluyeron reanimaciones consideradas fútiles. Se tomaron como variables resultado el estado neurológico al alta hospitalaria y al seguimiento de los pacientes, siguiendo el modelo de la Pediatric Cerebral Performance Category. El periodo fue del 1 de enero de 2008 al 31 de diciembre de 2019. Se realizaron dos encuestas, en mayo del 2021 y enero del 2023 con un periodo de seguimiento entre 1 y 13 años. RESULTADOS: De los 13.778 pacientes, 277 (2,0%) eran menores de 16 años; 137 (49,5%) trasladados al hospital, 99 de ellos (35,7%) con recuperación de circulación espontánea. Recibieron el alta hospitalaria 36 pacientes (13%). En el seguimiento, mediana (RIC) de 2.172 [978-3.035] días, 31 pacientes (86,1%) seguían con vida, 3 pacientes fallecieron y en dos casos no obtuvimos información. Dos pacientes sufrieron un empeoramiento del estado neurológico y 6 mejoraron. Finalmente, 27 de los 31 pacientes (87,1%) que completaron el seguimiento tenían una buena situación neurológica (PCPC1-2). CONCLUSIONES: A pesar de presentar una incidencia baja, la supervivencia con buen estado neurológico al alta hospitalaria de la parada cardiorrespiratoria extrahospitalaria pediátrica es comparable a la del adulto. Los pacientes pediátricos que recibieron el alta hospitalaria tras una parada cardiorrespiratoria extrahospitalaria mantuvieron o mejoraron su estado neurológico en el seguimiento a largo plazo.

RESUMEN

Objective: To evaluate the safety of COVID-19 vaccines in patients with multiple sclerosis (MS) by assessing their impact on serum neurofilament light chain (sNfL) levels as a marker of neuroaxonal damage. Methods: Single-center observational longitudinal study including patients with MS who consecutively received their initial vaccination against SARS-CoV-2 at Hospital Universitario Ramón y Cajal, following the first national immunization program in Spain. Serum samples were collected at baseline and after receiving the second dose of the vaccine. sNfL levels were quantified using the single molecule array (SIMOA) technique. Adverse events, including clinical or radiological reactivation of the disease, were recorded. Results: Fifty-two patients were included (median age, 39.7 years [range, 22.5-63.3]; 71.2% female). After SARS-CoV-2 vaccination, no increased inflammatory activity, either determined by the presence of relapses and/or new MRI lesions and/or high sNfL levels, was detected. Accordingly, there was no difference between median sNfL levels before and after vaccination (5.39 vs. 5.76 pg/ml, p=0.6). Despite this, when looking at baseline patient characteristics before vaccination, younger age associated with disease activity after vaccination (OR 0.87, 95% CI: 0.77-0.98, p=0.022). Larger studies are needed to validate these results. Conclusion: COVID-19 vaccines did not cause reactivation of disease at a clinical, radiological or molecular level, thus suggesting that they are safe in MS patients.

RESUMEN

Importance: Ambient air pollution and antimicrobial resistance pose significant global public health challenges. It is not known whether ambient air pollution is associated with increased consumption of antimicrobials. Objective: To assess whether a short-term association exists between ambient air pollution levels and antimicrobial consumption among the general population seeking primary care consultations for acute respiratory symptoms. Design, Setting, and Participants: This 2-stage cross-sectional ecological time series analysis study using data on daily ambient air pollution and antimicrobial consumption was conducted in the 11 largest cities in Catalonia, Spain, from June 23, 2012, to December 31, 2019, among all inhabitants aged 12 years or older. Statistical analysis was performed from November 2022 to December 2023. Exposures: Daily ambient air pollution (particulate matter of 10 µg/m3 [PM10], particulate matter of 2.5 µg/m3 [PM2.5], and nitrogen dioxide [NO2]). Main Outcomes and Measures: The main outcome was antimicrobial consumption associated with primary care consultations for acute respiratory symptoms in the 30 days before and after the dispensing of the antimicrobial. Antimicrobial consumption was measured as defined daily doses (DDDs) per 1000 inhabitants per day. Results: Among 1 938 333 inhabitants (median age, 48 years [IQR, 34-65 years]; 55% female participants), there were 8 421 404 antimicrobial dispensations, with a median of 12.26 DDDs per 1000 inhabitants per day (IQR, 6.03-15.32 DDDs per 1000 inhabitants per day). The median adjusted morbidity score was 2.0 (IQR, 1.0-5.0). For the 1 924 814 antimicrobial dispensations associated with primary care consultations for acute respiratory symptoms, there was a significant correlation between increases of 10 µg/m3 in the concentration of the 3 pollutants studied and heightened antimicrobial consumption at day 0 (PM10: relative risk [RR], 1.01 [95% CI, 1.01-1.02]; PM2.5: RR, 1.03 [95% CI, 1.01-1.04]; NO2: RR, 1.04 [95% CI, 1.03-1.05]). A delayed association emerged between increases in PM2.5 concentration and antimicrobial consumption between day 7 (RR, 1.00 [95% CI, 1.00-1.01]) and day 10 (RR, 1.00 [95% CI, 1.00-1.01]) after exposure. Conclusions and Relevance: In this 2-stage cross-sectional study using ecological time series analysis, short-term exposure to air pollution was associated with increased antimicrobial use associated with primary care consultations for acute respiratory symptoms in the general population. This finding could contribute to informing policy decisions aimed at reducing air pollution and its associated risks, thereby promoting respiratory health and reducing antimicrobial use.

RESUMEN

BACKGROUND: Respiratory syncytial virus (RSV) is associated with substantial morbidity among infants. This study modelled the potential public health and economic impact of nirsevimab, a long-acting monoclonal antibody, as an immunoprophylactic strategy for all infants in Spain in their first RSV season. METHODS: A static decision-analytic model of the Spanish birth cohort during its first RSV season was developed to estimate the impact of nirsevimab on RSV-related health events and costs versus the standard of practice (SoP). Spain-specific costs and epidemiological data were used as model inputs. Modelled outcomes included RSV-related outpatient visits, emerging room (ER) visits, hospitalisations - including pediatric intensive care unit (PICU) admission, mechanical ventilation, and inpatient mortality. RESULTS: Under the current SoP, RSV caused 151,741 primary care visits, 38,798 ER visits, 12,889 hospitalisations, 1,412 PICU admissions, and 16 deaths over a single season, representing a cost of €71.8 million from a healthcare payer perspective. Universal immunisation of all infants with nirsevimab was expected to prevent 97,157 primary care visits (64.0% reduction), 24,789 ER visits (63.9%), 8,185 hospitalisations (63.5%), 869 PICU admissions (61.5%), and 9 inpatient deaths (52.6%), saving €47.8 million (62.4%) in healthcare costs. CONCLUSIONS: These results suggest that immunisation with nirsevimab of all infants experiencing their first RSV season in Spain is likely to prevent thousands of RSV-related health events and save considerable costs versus the current SoP.

RESUMEN

BACKGROUND: The aim of this study is to describe major trauma cases in Navarre and analyze differences based on mortality groups, sex, and mode of injury. METHODS: Cross-sectional study of major traumas (severity =3) registered in Navarre between 2010 and 2019. We analyzed the type of trauma, intentionality, the mode of injury, and the affected anatomical area. The odds ratio for major trauma associated with different variables was calculated. RESULTS: The study included 2,609 patients; mean age was 54.7 years (0-101) and 70.9% were male. A predominance of accidental (84%) / blunt (94.7%) major traumas was recorded, primarily resulting from falls (46.5%) and car accidents (18.4%). Women experienced more falls and pedestrian accidents, while men had more motorcycle, bicycle, knife/firearm accidents, and contusions. Most major traumas affected the head and thorax. Head trauma was significantly more common in deceased individuals and women, while thoracic trauma was more frequent in patients who died on-site and in men. Head injuries were caused by falls from low heights and firearms, whereas thoracic injuries resulted from car accidents and falls from height. The risk of major trauma decreased with age; deceased patients were between two and three times more likely to present lesions in all anatomical areas. CONCLUSIONS: Gender differences are observed in intentionality, type, and mode of injury. Head and thoracic injuries are potentially life-threatening and abdominal and extremity/pelvic ring injuries are associated with early deaths. This suggests that the extent and severity of these injuries complicate treatment and management.

RESUMEN

The aging of the world population is now an unquestionable fact. The World Health Organization (WHO) points out in its World Report on Aging and Health published in 2015 two main causes: the increase in life expectancy and the decrease in fertility rates. The United Nations (UN) announced that Spain will become the oldest country in the world in 2050, with 44% of citizens over 60 years of age and the median age of 55.2 years. Whether this event is interpreted optimistically or as a demographic problem will depend on the quality of the years of life gained.

El envejecimiento de la población mundial es ya un hecho incuestionable. La Organización Mundial de la Salud (OMS) señala en su Informe mundial sobre el envejecimiento y la salud publicado en 2015 dos causas principales: el aumento en la esperanza de vida y el descenso de las tasas de fecundidad. La Organización de Naciones Unidas (ONU) anunció que España llegará a ser el país más envejecido del mundo en 2050, siendo el 44% de la ciudadanía mayor de 60 años y la mediana de edad de 55,2 años. Si este acontecimiento es interpretado con optimismo o como un problema demográfico dependerá de la calidad de los años de vida ganados.

RESUMEN

Objective: Covitality is a meta-construct of positive intra/interpersonal self-schemas that organize and process life experiences. Its synergy favors psychosocial adjustment and prevents mental health problems during adolescence. At these ages, suicide is one of the leading causes of death worldwide. The purpose of this study was to determine which psychosocial strengths of the covitality model could combat adolescent suicide spectrum. Method: Participants were 5,528 Spanish adolescents aged 12-18 years, 50.74% females. The assessment protocol was completed in schools, under the supervision of the research staff. Statistical analyses were conducted using hurdle models, i.e., modeling zero-inflated count data. This process provided two sets of outcomes: the association - in probabilistic terms - between psychosocial strengths and the absence of suicide indicators (i.e., non-occurrence) and the association of these assets - via regression coefficients - with increased experimentation (i.e., duration/quantity). Results: All psychosocial strengths of the covitality model were related to the non-ocurrence of suicidal thoughts and behaviors, but not all to a shorter duration/quantity of their phenotypic manifestations. Covitality obtained greater association values on suicidal tendencies than its components analyzed independently. Belief in self and engaged living were the second-order factors with the higher estimating capacity. Specifically, emotional self-awareness, enthusiasm, gratitude, family support, and behavioral self-control were key first-order assets. Conclusions: These findings suggest that training adolescents in covitality assets could be an effective strategy for universal prevention against premature suicide. Moreover, this study provide evidence on which psychosocial strengths could counteract each phenotypic manifestation of suicide in order to customize selective and indicated preventive actions.

RESUMEN

Introduction: Data on the increase in mortality during the COVID-19 pandemic based on individuals' socioeconomic positions are limited. This study examines this increase in mortality in Spain during the epidemic waves of 2020 and 2021. Methods: We calculated the overall and cause-specific mortality rates during the 2017-2019 pre-pandemic period and four epidemic periods in 2020 and 2021 (first, second, third-fourth, and fifth-sixth waves). Mortality rates were analyzed based on educational levels (low, medium, and high) and across various age groups (25-64, 65-74, and 75+). The increase in mortality during each epidemic period compared to the pre-pandemic period was estimated using mortality rate ratios (MRR) derived from Poisson regression models. Results: An inverse educational gradient in overall mortality was observed across all periods; however, this pattern was not consistent for COVID-19 mortality in some age groups. Among those aged 75 years and older, highly educated individuals showed higher COVID-19 mortality during the first wave. In the 25-64 age group, individuals with low education experienced the highest overall mortality increase, while those with high education had the lowest increase. The MRRs were 1.21 and 1.06 during the first wave and 1.12 and 0.97 during the last epidemic period. In the 65-74 age group, highly educated individuals showed the highest overall mortality increase during the first wave, whereas medium-educated individuals had the highest increase during the subsequent epidemic periods. Among those aged 75 and older, highly educated individuals exhibited the highest overall mortality increase while the individuals with low education showed the lowest overall mortality increment, except during the last epidemic period. Conclusion: The varying educational patterns of COVID-19 mortality across different age groups contributed to the disparities of findings in increased overall mortality by education levels during the COVID-19 pandemic.

RESUMEN

OBJECTIVE: Air pollution is a global public health issue, with particulate matter (PM) being the pollutant with the greatest impact on health. The main objective of this article was to estimate the impact of mortality attributable to particulate pollution in the city of Valencia during the period 2015-2017. METHODS: The Health Impact Assessment (HIA) methodology from the Aphekom project was used. Scenarios of a 5 µg/m3 reduction in the annual mean concentration of PM10 and PM2.5 were employed, along with the assumption of meeting the World Health Organization (WHO) recommendations in effect during the study period, to estimate both short- and long-term impacts. RESULTS: The estimated average concentrations for 2015-2017 were 18.4 µg/m3 for PM10 and 12.3 µg/m3 for PM2.5. The short-term HIA, assuming a reduction of 5 µg/m3 in the averages, resulted in a total of 65.4 premature deaths that could be postponed during that period (21.8 annually), corresponding to a rate of 2.8 deaths per 100,000 inhabitants. In the long term, if PM2.5 concentrations had been reduced by 5 µg/m3, 124 premature deaths could have been postponed annually. CONCLUSIONS: The annual average concentrations of these pollutants meet the limits set by European regulations. However, compared to WHO recommendations, PM2.5 levels are higher by 2.3 µg/m3. An air quality scenario in line with WHO recommendations would have resulted in a reduction of 122 premature deaths annually.

OBJETIVO: La contaminación del aire es un problema de Salud Pública de importancia global, siendo las partículas en suspensión (PM) el contaminante con mayor impacto en la salud. El objetivo principal de este artículo fue estimar el impacto en mortalidad atribuible a la contaminación por partículas en la ciudad de València en el periodo 2015-2017. METODOS: Se utilizó la metodología para la Evaluación del Impacto en Salud (EIS) del proyecto Aphekom. Se realizó un estudio descriptivo y para la correlación se emplearon los escenarios de reducción de la media anual de 5 µg/m3 en la concentración de PM10 y de PM2,5 y el supuesto de cumplir las recomendaciones de la Organización Mundial de la Salud (OMS) vigentes en el periodo a estudio para estimar el impacto a corto y largo plazo. RESULTADOS: Las concentraciones estimadas del promedio 2015-2017 para PM10 y PM2,5 fueron de 18,4 µg/m3 y 12,3 µg/m3, respectivamente. La EIS a corto plazo, en el supuesto de reducir en 5 µg/m3 las medias, tuvo como resultado un total de 65,4 muertes prematuras que se podrían posponer en ese periodo (21,8 anuales), correspondiendo con una tasa de 2,8 defunciones por cada 100.000 habitantes. A largo plazo, si se hubiesen reducido las concentraciones de PM2,5 en 5 µg/m3, se hubieran podido posponer 124 muertes prematuras anuales. CONCLUSIONES: Las concentraciones medias anuales de estos contaminantes se ajustan a los límites marcados por la normativa europea. Sin embargo, respecto a las recomendaciones de la OMS, los niveles de PM2,5 son superiores en 2,3 µg/m3. Un escenario de calidad del aire conforme a las recomendaciones de la OMS se hubiera traducido en una reducción de 122 defunciones prematuras anuales.

RESUMEN

OBJECTIVE: The use of non-pharmacological preventive measures during the COVID-19 pandemic has helped to reduce the incidence of multiple airborne or contact diseases. The objective of this paper was to evaluate the impact that all preventive measures have had on the transmission of different microorganisms, both by respiratory and contact transmission. METHODS: We compared the incidence of different infectious episodes coded with the CIAP-2 code (International Classification of Primary Care second edition of the WONCA International Classification Committee) collected from the computerized history of primary care, both with respiratory tract and digestive tract involvement, in the period from March 2018 to February 2020 (pre-pandemic period) and from March 2020 to February 2022 (pandemic period). The data corresponded to the entire region, with an estimated average population for the four years of 650,000 people. The statistical treatment of the data consisted of a descriptive analysis with the calculation of absolute values and percentages. Rates were calculated and compared using data provided by the National Institute of Statistics as a denominator. The P was obtained by statistical comparison by the exact method. A comparison of rates was made. RESULTS: The incidence in the number of CIAP-2 episodes studied, both corresponding to respiratory and gastrointestinal pathologies, comparing the period March 2018-February 2020 with the period March 2020-February 2022 decreased by 65.81%, from 534,439 cases to 182,707. CONCLUSIONS: The preventive measures applied during the pandemic produce a significant decrease in pathology involving the respiratory or the digestive tract.

OBJETIVO: El uso de medidas preventivas no farmacológicas durante la pandemia de la COVID-19 ayudó a reducir la incidencia de múltiples enfermedades de transmisión aérea o por contacto. El objetivo de este trabajo fue evaluar el impacto que habían tenido todas las medidas preventivas en la transmisión de diferentes microorganismos, tanto por transmisión respiratoria como por contacto. METODOS: Comparamos la incidencia de diferentes episodios infecciosos codificados con el código CIAP-2 (Clasificación Internacional de Atención Primaria, segunda edición, del Comité de Clasificación Internacional WONCA-World Organization of Family Doctors) recogidos de la historia informatizada de Atención Primaria, tanto con afectación del tracto respiratorio como del tracto digestivo, en el período de marzo de 2018 a febrero de 2020 (período prepandemia) y de marzo de 2020 a febrero de 2022 (período de pandemia). Los datos correspondieron a toda la región, con una población media estimada para los cuatro años de 650.000 personas. El tratamiento estadístico de los datos consistió en un análisis descriptivo con el cálculo de valores absolutos y porcentajes. Se calcularon y compararon tasas tomando como denominador los datos proporcionados por el Instituto Nacional de Estadística. La P fue obtenida mediante comparación estadística por el método exacto. Se realizó una comparación de tasas. RESULTADOS: La incidencia en el número de episodios CIAP-2 estudiados, tanto correspondientes a patología respiratoria como gastrointestinal, comparando el periodo de marzo de 2018-febrero de 2020 con el periodo marzo de 2020-febrero de 2022, disminuyó en un 65,81%, pasando de 534.439 casos a 182.707. CONCLUSIONES: Las medidas preventivas aplicadas durante la pandemia producen una disminución significativa de la patología del tracto respiratorio o digestivo.

RESUMEN

BACKGROUND: Patients with atrial fibrillation (AF) often have concomitant long-term conditions that negatively impact their quality of life and the clinical management they receive. The AFFIRMO study aimed to identify the needs, quality performance indicators (QPIs), and outcomes relevant to patients, caregivers and healthcare professionals (HCPs) to improve the care of patients with AF. METHODS: An on-line survey to collect the key needs, QPIs, and outcomes relevant to patients with AF, their caregivers and HCPs, was distributed between May 2022 and January 2023 in five countries (UK, Italy, Denmark, Romania and Spain). Results from the on-line survey were discussed in a three-round Delphi process with international representatives of patients with AF, caregivers, and HCPs to determine the key needs, QPIs and outcomes for the management of patients with AF and multimorbidity. RESULTS: 659 patients (47.2% males, mean (SD) age 70.9 (10.2) years), 201 caregivers (26.9% males, mean (SD) age: 58.3 (SD 15.2) years), and 445 HCPs (57.8% males, mean (SD) age 47.4 (10.6) years) participated in the survey. An initial list of 27 needs, 9 QPIs, and 17 outcomes were identified. Eight patients, two caregivers, and 11 HCPs participated in the Delphi process. Nineteen (70%) needs, 8 (89%) QPIs, and 13 (76%) outcomes reached "consensus in", and were included in the final list. CONCLUSIONS: The final key needs, QPIs and outcomes obtained from the Delphi process will inform the AFFIRMO clinical trial, which aims to test the iABC app which incorporates an empowerment toolbox for patients and their caregivers, providing information to improve patient engagement and empowerment to help improve the clinical and self-management of patients with AF in the context of multimorbidity.

RESUMEN

The Canary Islands inhabitants, a recently admixed population with significant North African genetic influence, has the highest incidence of childhood-onset type 1 diabetes (T1D) in Spain and one of the highest in Europe. HLA accounts for half of the genetic risk of T1D. AIMS: To characterize the classical HLA-DRB1 and HLA-DQB1 alleles in children from Gran Canaria with and without T1D. METHODS: We analyzed classic HLA-DRB1 and HLA-DQB1 alleles in childhood-onset T1D patients (n = 309) and control children without T1D (n = 222) from the island of Gran Canaria. We also analyzed the presence or absence of aspartic acid at position 57 in the HLA-DQB1 gene and arginine at position 52 in the HLA-DQA1 gene. Genotyping of classical HLA-DQB1 and HLA-DRB1 alleles was performed at two-digit resolution using Luminex technology. The chi-square test (or Fisher's exact test) and odds ratio (OR) were computed to assess differences in allele and genotype frequencies between patients and controls. Logistic regression analysis was also used. RESULTS: Mean age at diagnosis of T1D was 7.4 ± 3.6 years (46% female). Mean age of the controls was 7.6 ± 1.1 years (55% female). DRB1*03 (OR = 4.2; p = 2.13-13), DRB1*04 (OR = 6.6; p ≤ 2.00-16), DRB1* 07 (OR = 0.37; p = 9.73-06), DRB1*11 (OR = 0.17; p = 6.72-09), DRB1*12, DRB1*13 (OR = 0.38; p = 1.21-05), DRB1*14 (OR = 0.0; p = 0.0024), DRB1*15 (OR = 0.13; p = 7.78-07) and DRB1*16 (OR = 0.21; p = 0.003) exhibited significant differences in frequency between groups. Among the DQB1* alleles, DQB1*02 (OR: 2.3; p = 5.13-06), DQB1*03 (OR = 1.7; p = 1.89-03), DQB1*05 (OR = 0.64; p = 0.027) and DQB1*06 (OR = 0.19; p = 6.25-14) exhibited significant differences. A total of 58% of the studied HLA-DQB1 genes in our control population lacked aspartic acid at position 57. CONCLUSIONS: In this population, the overall distributions of the HLA-DRB1 and HLA-DQB1 alleles are similar to those in other European populations. However, the frequency of the non-Asp-57 HLA-DQB1 molecules is greater than that in other populations with a lower incidence of T1D. Based on genetic, historical and epidemiological data, we propose that a common genetic background might help explain the elevated pediatric T1D incidence in the Canary Islands, North-Africa and middle eastern countries.

RESUMEN

INTRODUCTION: Breastfeeding appears to protect the onset of obesity in infants. The aim is to know whether breastfeeding duration is associated with the risk of obesity in infants and toddlers aged 12 and 24 months. MATERIAL AND METHODS: Prospective longitudinal study in a cohort of children born in Spain between April 2017 and March 2018 (LAyDI study) in the paediatric primary care system conducted in the framework of the PAPenRed research network. Analysis of breastfeeding duration (group 1: fewer than 6 months; group: more than 6 months) and its association with anthropometric variables. RESULTS: A total of 1495 patients attended the 12 months preventive child health visit and 1073 patients the 24 months visit. We found a statistically significant association between breastfeeding duration and weight-for-age, BMI-for-age and weight-for-length/height at 12 and 24 months; breastfeeding duration of less than 6 months was significantly associated with overweight and obesity (based on BMI-for-age and weight-for-length/height) at ages 12 and 24 months. Maternal pre-pregnancy BMI acted as a modifier on the association between breastfeeding duration and overweight and obesity (based on BMI-for-age). CONCLUSIONS: A breastfeeding duration of less than 6 months is associated with a higher percentage of overweight and obesity at ages 12 and 24 months, although maternal pre-pregnancy BMI modifies this relationship at 24 months.

RESUMEN

OBJECTIVE: To calculate the prevalence of physical restraint (PR) use in Spanish PICUs and (2) to analyze the correlation between the prevalence of PR use and the sociodemographic, clinical variables of the patients and the PICU structural and organizational variables. METHODS: We conducted a multicenter prevalence study from January 2022 to January 2023 in Spanish PICUs. The method of data collection was by direct observation, review of the patient's medical history, and asking the professionals involved in the patient's care. Three weekly 24-hour prevalence observations (morning, afternoon, and night) were conducted for 6 months. RESULTS: A total of 336 patients were included in the study, obtaining an overall crude prevalence of PR use of 16 % (95 %CI: 15 %-17.7 %). Pediatric patients with respiratory pathology received the highest number of hours of PR, with significant differences observed when comparing respiratory cases with post-surgical cases. Statistical significance was also observed when comparing the mean scores of hours of PR according to admission diagnosis (p = 0.01), with respiratory patients being the ones who were restrained the longest (24 h [20-24]) and infectious patients the least (15 h [14-20]). Patients who receive PR upon admission remain in this situation for more hours (24 h [15-24] and in the PICUs that specifically recorded PR application, fewer hours of PR occurred (20 h [4-24]). CONCLUSIONS: The use of PR is still present in the PICUs analyzed, with a crude prevalence of 16%. Factors such as the reason for admission, the use of respiratory support, and the reason for application of PR were linked to the hours of use of PR. IMPLICATIONS FOR CLINICAL PRACTICE: Knowing the prevalence of PR use will make professionals aware that it is still necessary to implement policies that avoid its use to prevent the side effects they have in pediatric patients.

RESUMEN

OBJECTIVE: To examine whether socioeconomic status is associated with prognosis after the diagnosis of hypertension (HTN), in a population older than 65 years, in the community setting. DESIGN: Retrospective cohort study. SETTING: All the primary care centres of the Community of Madrid (n=392). PARTICIPANTS: All patients (>65 years) with a new diagnosis of HTN in 2007-08, without previous kidney or cardiovascular (K/CV) events (n=21 754).Patient records from primary care electronic health records and Spanish mortality database were analysed from January 2007 through December 2018. Sociodemographic data such as age, gender, Area Deprivation Index (MEDEA-Mortalidad en áreas pequeñas Españolas y Desigualdades Socioeconómicas y Ambientales-Index in quintiles), and characteristics, such as smoking, type 2 diabetes mellitus and hypercholesterolaemia, were collected at the time of enrolment. PRIMARY AND SECONDARY OUTCOME MEASURES: The occurrence of K/CV events (including mortality from these causes) and total mortality were evaluated using Cox regression. RESULTS: Patients had a mean age of 73.5 (SD 6.5) years, and 63.5% were women. The median follow-up was 128.7 months (IQR: 110.6-136.7 months). There were 10 648 first K/CV events, including 1508 deaths from these causes and 4273 deaths from other causes. Adjusted for age, gender, smoking, diabetes and hypercholesterolaemia, when comparing the third, fourth and last quintiles (less affluent) of the Deprivation Index with respect to the first quintile, the hazard of K/CV events increased by 14.8% (95% CI: 3.3 to 27.6%), 16.0% (95% CI: 6.4 to 26.4%) and 19.1% (95% CI: 8.9 to 30.2%), respectively. The MEDEA Index was not associated with differences in adjusted total mortality. CONCLUSION: Living in a low socioeconomic status area is associated with an increase in kidney or cardiovascular events in hypertensive patients diagnosed after age 65 years, which will result in a significant increase in disease burden even if not related to an increase in total mortality.

RESUMEN

INTRODUCTION: Air pollution is a major health risk factor. Ports might be an understudied source of air pollution. METHODS: We conducted a spatial health impact assessment (HIA) of port-sourced air pollution for Barcelona for 2017 at the neighbourhood level. Total NO2 and PM10 and port-sourced NO2, PM10 and PM2.5 concentrations were available through the ADMS-Urban model. Population data, mortality and morbidity data, and risk estimates were obtained. We followed standard HIA methodologies and calculated relative risks and impact fractions for 1.35 million adults living in 73 neighbourhoods. RESULTS: The city-wide mean total NO2 and PM10 concentrations were 37.88 µg/m3 (range: 19.61-52.17 µg/m3) and 21.68 µg/m3 (range: 17.33-26.69 µg/m3), respectively, of which 7% (range: 2-36%) and 1% (range: 0-7%) were port-sourced, respectively. The mean port-sourced PM2.5 concentration was 0.19 µg/m3 (range: 0.06-1.38 µg/m3). We estimated that 1,123 (PI: 0-3,060) and 1,230 (95% CI: 0-2,566) premature deaths were attributable to total NO2 and PM10, respectively, of which 8.1% (91; PI: 0-264) and 1.1% (13; 95% CI 0-29) were attributable to port-sourced NO2 and PM10, respectively. 20 (95% CI: 15-26) premature deaths were attributable to port-sourced PM2.5. Additionally, a considerable morbidity burden and losses in life expectancy were attributable to port-sourced air pollution. Neighbourhoods closest to the port in the south-east were most adversely affected, gradually decreasing towards the north-west. CONCLUSIONS: The port is an understudied air pollution source in Barcelona with strong health impacts. Cities need local insight into health risk factors, their sources, attributable burdens and distributions for defining targeted policies.
