Factors associated to the presence of headache in patients with influenza infection and its consequences: a 2010-2020 surveillance-based study.

Headache is a common symptom of influenza infection; however, its causes and consequences remain uncertain. In this manuscript, we analyzed which demographic and clinical factors were associated with the presence of headache during the course of influenza infection and whether patients with headache had a different prognosis, evaluated by need of hospitalization, sick leave or school absenteeism. The influence study (NCT05704335) was an observational study that analyzed data routinely collected from the Health Sentinel Network between 2010 and 2020. During the study period, 7832 cases were considered, among which, 5275 (67.4%) reported headache. The presence of headache was independently associated with myalgia (2.753; 95%CI: 2.456-3.087, P < 0.001), asthenia (OR: 1.958; 95%CI: 1.732-2.214, P < 0.001), shivering (OR: 1.925; 95%CI: 1.718-2.156, P < 0.001), nasopharyngeal erythema (OR: 1.505; 95%CI: 1.293-1.753, P < 0.001), fever (OR: 1.469; 95%CI: 1.159-1.861; P = 0.001), sudden onset of symptoms (OR: 1.380; 95%CI: 1.120-1.702, p = 0.004), female sex (OR: 1.134; 95%CI: 1.023-1.257, P = 0.018), and gastrointestinal symptoms (OR: 1.169; 95%CI: 1.039-1.315; P = 0.01). Patients with headache had a sex and age adjusted lower odds of being referred to the hospital (OR: 0.463; 95%CI: 0.264-0.812, P = 0.007) and a higher odd of having a sick leave and/or school absenteeism (absenteeism (OR: 1.342; 95%CI: 1.190-1.514, P < 0.001). In conclusion, the presence of headache seems associated with symptoms caused by the innate immune response. These findings support a headache pathophysiology linked with the innate immune response. Due to the potential negative consequences and its treatable nature, clinicians should systematically evaluate it and, whenever necessary, treat it too.

Comprehensive surveillance of acute respiratory infections during the COVID-19 pandemic: a methodological approach using sentinel networks, Castilla y León, Spain, January 2020 to May 2022.

BackgroundSince 1996, epidemiological surveillance of acute respiratory infections (ARI) in Spain has been limited to seasonal influenza, respiratory syncytial virus (RSV) and potential pandemic viruses. The COVID-19 pandemic provides opportunities to adapt existing systems for extended surveillance to capture a broader range of ARI.AimTo describe how the Influenza Sentinel Surveillance System of Castilla y León, Spain was rapidly adapted in 2020 to comprehensive sentinel surveillance for ARI, including influenza and COVID-19.MethodsUsing principles and methods of the health sentinel network, we integrated electronic medical record data from 68 basic surveillance units, covering 2.6% of the regional population between January 2020 to May 2022. We tested sentinel and non-sentinel samples sent weekly to the laboratory network for SARS-CoV-2, influenza viruses and other respiratory pathogens. The moving epidemic method (MEM) was used to calculate epidemic thresholds.ResultsARI incidence was estimated at 18,942 cases per 100,000 in 2020/21 and 45,223 in 2021/22, with similar seasonal fold increases by type of respiratory disease. Incidence of influenza-like illness was negligible in 2020/21 but a 5-week epidemic was detected by MEM in 2021/22. Epidemic thresholds for ARI and COVID-19 were estimated at 459.4 and 191.3 cases per 100,000 population, respectively. More than 5,000 samples were tested against a panel of respiratory viruses in 2021/22.ConclusionExtracting data from electronic medical records reported by trained professionals, combined with a standardised microbiological information system, is a feasible and useful method to adapt influenza sentinel reports to comprehensive ARI surveillance in the post-COVID-19 era.

End-of-life communication in advanced cancer: international trends (2009-2014).

OBJECTIVE: To examine trends in end-of-life communication with people with cancer in general practice. METHODS: Mortality follow-back survey among general practitioners (GPs) in representative epidemiological surveillance networks in Belgium (BE), the Netherlands (NL) and Spain (ES) in 2009-2010 (ES: 2010-2011) and 2013-2014. Using a standardised form, GPs registered all deceased adult patients in their practice and reported for five end-of-life care topics whether they had been discussed with the patient. Non-sudden cancer deaths were included (n=2306; BE: 1233; NL: 729; ES: 344). RESULTS: A statistically significant increase was found between 2009/2010 and 2014 in the prevalence of communication about diagnosis (from 84% to 94%) and options for end-of-life care (from 73% to 90%) in BE, and in GPs' awareness of patients' preferences for medical treatment and a proxy decision-maker in BE (from 41% and 20% up to 53% and 28%) and the NL (from 62% and 32% up to 70% and 52%). Communication about options for end-of-life care and psychosocial problems decreased in the NL (from 88% and 91% down to 73%) and ES (from 76% and 77% down to 26% and 39%). CONCLUSION: Considerable change in GP-patient communication seems possible in a relatively short time span, but communication cannot be assumed to increase over time. Increasing specialisation of care and task differentiation may lead to new roles in communication for healthcare providers in primary and secondary care. Improved information sharing between GPs and other healthcare providers may be necessary to ensure that patients have the chance to discuss important end-of-life topics.

Primary palliative care for older people in three European countries: a mortality follow-back quality study.

BACKGROUND: Many older people with serious chronic illnesses experience complex health problems for which palliative care is indicated. We aimed to examine the quality of primary palliative care for people aged 65-84 years and those 85 years and older who died non-suddenly in three European countries. METHODS: This is a nationwide representative mortality follow-back study. General practitioners (GPs) belonging to epidemiological surveillance networks in Belgium (BE), Italy (IT) and Spain (ES) (2013-2015) registered weekly all deaths in their practices. We included deaths of people aged 65 and excluded sudden deaths judged by GPs. We applied a validated set of quality indicators. RESULTS: GPs registered 3496 deaths, of which 2329 were non-sudden (1126 aged 65-84, 1203 aged 85+). GPs in BE (reference category) reported higher scores than IT across almost all indicators. Differences with ES were not consistent. The score in BE particularly differed from IT on GP-patient communication (aged 65-84: 61% in BE vs 20% in IT (OR=0.12, 95% CI 0.07 to 0.20) aged 85+: 47% in BE vs 9% in IT (OR=0.09, 95% CI 0.05 to 0.16)). Between BE and ES, we identified a large difference in involvement of palliative care services (aged 65-84: 62% in BE vs 89% in ES (OR=4.81, 95% CI 2.41 to 9.61) aged 85+: 61% in BE vs 77% in ES (OR=3.1, 95% CI 1.71 to 5.53)). CONCLUSIONS: Considerable country differences were identified in the quality of primary palliative care for older people. The data suggest room for improvement across all countries, particularly regarding pain measurement, GP-patient communication and multidisciplinary meetings.

Prevalencia de sobrepeso y obesidad infantil. Estudio de una cohorte en Castilla y León, España / Prevalence of overweight and obesity in child population. A study of a cohort in Castile and Leon, Spain

Introducción: Varios estudios advierten que el sobrepeso y la obesidad se han convertido en una epidemia con graves consecuencias sobre la salud de la población. El objetivo del presente estudio es estimar la prevalencia de sobrepeso y obesidad en Castilla y León en una muestra de niños a los 6, 11 y 14 años de edad, describir su evolución y su asociación con hábitos de vida y antecedentes. Metodología: Estudio observacional, de cohorte retrospectivo, realizado por los pediatras de la Red Centinela Sanitaria, que se enmarca en un proyecto conjunto con el Centro Nacional de Investigación sobre la Evolución Humana de Burgos para conocer el patrón de crecimiento y desarrollo de la población infantil de Castilla y León. En 2012 se realizó un examen de salud y una recogida retrospectiva a partir de la historia clínica en una muestra de 326 niños, de la cohorte de nacidos en 1998. Resultados: Según los criterios de la OMS, a los 14 años había un 25,3% de sobrepeso entre los niños y un 18,5% entre las niñas. En cuanto a la obesidad, esta afectaba al 8,2 y 4,8%, respectivamente. A los 11 años se produce un pico de sobrepeso en las niñas y de obesidad en los niños. El entorno urbano-no urbano, la calidad y duración del sueño, así como el índice de masa corporal (IMC) de los padres han sido algunos de los factores asociados con el peso de los niños. Discusión: En Castilla y León, como en otras poblaciones de nuestro entorno, existe un grave problema de sobrepeso y obesidad infantil. Para su control, es necesario profundizar sobre los estilos de vida y los antecedentes relacionados con el nacimiento, así como el cálculo de la velocidad de crecimiento en la edad pediátrica

Introduction: Several studies warn that overweight and obesity have become an epidemic with severe consequences in the population's health. The objetive of the present study is to estimate the prevalence of overweight and obesity in Castile and Leon in a sample of children at 6, 11 and 14 years of age, to describe its evolution and its association with life habits and antecedents. Material and methods: Observational study, retrospective cohort, performed by the pediatricians of the Health Sentinel Network. The study is part of a joint Project with the National Research Center on Human Evolution (CENIEH) in Burgos to know the pattern of growth and development of the child population of Castile and Leon. In 2012, a health examination and a retrospective collection were carried out based on the clinical history of a simple of 326 children, from the cohort was born in 1998. Results: Following the WHO references, at age 14 there was 25.3% of boys and 18.5% of girls with overweight. Obesity was estimated to affect the 8.2% and 4.8% of them respectively. At 11 years of age there was the maximum of overweight in girls and of obesity in boys. At the urban-non urban environment, quantity and quality of sleep and the parents' BMI have been some of the associated factors to weight level of the children. Discussion: In Castile and Leon, as in other populations of our environment, there is a severe problema of overweight and obesity. For their control it is necesary to deepen understanding of lifestyles and antecedents related to the birth as well as to calculate the growth rate in the pediatric age

Quality of primary palliative care for older people with mild and severe dementia: an international mortality follow-back study using quality indicators.

Background: measuring the quality of primary palliative care for older people with dementia in different countries is important to identify areas where improvements can be made. Objective: using quality indicators (QIs), we systematically investigated the overall quality of primary palliative care for older people with dementia in three different countries. Design/setting: a mortality follow-back survey through nation- and region-wide representative Sentinel Networks of General Practitioners (GPs) in Belgium, Italy and Spain. GPs registered all patient deaths in their practice. We applied a set of nine QIs developed through literature review and expert consensus. Subjects: patients aged 65 or older, who died non-suddenly with mild or severe dementia as judged by GPs (n = 874). Results: findings showed significantly different QI scores between Belgium and Italy for regular pain measurement (mild dementia: BE = 44%, IT = 12%, SP = 50% | severe dementia: BE = 41%, IT = 9%, SP = 47%), acceptance of approaching death (mild: BE = 59%, IT = 48%, SP = 33% | severe: BE = 41%, IT = 21%, SP = 20%), patient-GP communication about illness (mild: BE = 42%, IT = 6%, SP = 20%) and involvement of specialised palliative services (mild: BE = 60%, IT = 20%, SP = 77%). The scores in Belgium differed from Italy and Spain for patient-GP communication about medical treatments (mild: BE = 34%, IT = 12%, SP = 4%) and repeated multidisciplinary consultations (mild: BE = 39%, IT = 5%, SP = 8% | severe: BE = 36%, IT = 10%, SP = 8%). The scores for relative-GP communication, patient death outside hospitals and bereavement counselling did not differ between countries. Conclusion: while the countries studied differed considerably in the overall quality of primary palliative care, they have similarities in room for improvement, in particular, pain measurement and prevention of avoidable hospitalisations.

End-of-life care for people dying with dementia in general practice in Belgium, Italy and Spain: A cross-sectional, retrospective study.

AIM: To describe and compare end-of-life care for people with mild or severe dementia in general practice in Belgium, Italy and Spain, in terms of place of care, place of death, treatment aims, use of specialized palliative care and communication with general practitioners (GPs). METHODS: Cross-sectional retrospective survey was carried out of nationwide networks of GPs in Belgium, Italy and Spain, including patients who died aged 65 years or older in 2009-2011 and were judged by the GP to have had dementia (n = 1623). RESULTS: GPs reported a higher proportion of older people with severe dementia in Belgium (55%) than in Spain (46 %) and Italy (45 %), and a higher proportion of patients living in care homes (57% vs 18% and 13%, respectively). A palliative treatment aim was common in the last 3 months of life in all three countries. Specialized palliative care services were provided in 14% (Italy, severe dementia) to 38% (Belgium, severe dementia) of cases. Communication between GP and patient about illness-related topics occurred in between 50% (Italy) and 72% (Belgium) of cases of mild dementia, and 10% (Italy) to 32% (Belgium) of cases of severe dementia. Patient preferences for end-of-life care were known in a minority of cases. Few people (13-15 %) were transferred between care settings in the last week of life. CONCLUSIONS: Although overall treatment aims at the end of life are often aligned with a palliative care approach and transfer rates are low, there is room for improvement in end-of-life care for people with dementia in all countries studied, especially regarding early patient-GP communication.

Hospitalisations at the end of life in four European countries: a population-based study via epidemiological surveillance networks.

BACKGROUND: There is a paucity of cross-national population-based research on hospitalisations of people at the end of life. We aimed to compare, in four European countries, the frequency, time, length of and factors associated with hospitalisations in the last 3 months of life. METHODS: Population-based mortality follow-back study via Sentinel Networks of general practitioners (GPs) in Belgium, the Netherlands, Italy and Spain. Using a standardised form, GPs recorded the care in the last 3 months of life of every deceased practice patient (≥18 years; 1 January 2009 to 31 December 2011). Sudden deaths were excluded. RESULTS: We studied 4791 deaths that GPs described as non-sudden (66% of all registered deaths). Between 49% (the Netherlands) and 56% (Belgium) of patients were hospitalised at least once in the last 3 months of life. Readmissions were less frequent in the Netherlands (8%) than in the other countries (15-20%, p<0.001). Chances of being hospitalised increased over the last 10 days of life across countries but remained lowest in the Netherlands (Belgium: 21-37%, the Netherlands: 15-29%, Italy: 16-37%, Spain: 14-31%). Hospitalisations in the last week of life were more likely if patients resided at home rather than in a care home (ORs and 95% CIs Belgium: 1.94 (1.28 to 2.94); the Netherlands: 2.61 (1.10 to 6.18); Spain: 4.72 (1.64 to 13.57); non-significant in Italy) and less likely if the GP knew the patient's preferred place of death (ORs and 95% CIs Belgium: 0.52 (0.36 to 0.74); the Netherlands: 0.48 (0.25 to 0.91); Spain: 0.24 (0.13 to 0.44), non-significant in Italy). CONCLUSIONS: The use of hospitals at the end-of-life increased over the last weeks of life of patients in all countries studied, but remained lowest in the Netherlands, as did the rate of readmissions. This may be due to gatekeeping by GPs who are trained and supported in preventing hospital readmissions at the end of life.

Associations between Meteorological Parameters and Influenza Activity in Berlin (Germany), Ljubljana (Slovenia), Castile and León (Spain) and Israeli Districts.

BACKGROUND: Studies in the literature have indicated that the timing of seasonal influenza epidemic varies across latitude, suggesting the involvement of meteorological and environmental conditions in the transmission of influenza. In this study, we investigated the link between meteorological parameters and influenza activity in 9 sub-national areas with temperate and subtropical climates: Berlin (Germany), Ljubljana (Slovenia), Castile and León (Spain) and all 6 districts in Israel. METHODS: We estimated weekly influenza-associated influenza-like-illness (ILI) or Acute Respiratory Infection (ARI) incidence to represent influenza activity using data from each country's sentinel surveillance during 2000-2011 (Spain) and 2006-2011 (all others). Meteorological data was obtained from ground stations, satellite and assimilated data. Two generalized additive models (GAM) were developed, with one using specific humidity as a covariate and another using minimum temperature. Precipitation and solar radiation were included as additional covariates in both models. The models were adjusted for previous weeks' influenza activity, and were trained separately for each study location. RESULTS: Influenza activity was inversely associated (p<0.05) with specific humidity in all locations. Minimum temperature was inversely associated with influenza in all 3 temperate locations, but not in all subtropical locations. Inverse associations between influenza and solar radiation were found in most locations. Associations with precipitation were location-dependent and inconclusive. We used the models to estimate influenza activity a week ahead for the 2010/2011 period which was not used in training the models. With exception of Ljubljana and Israel's Haifa District, the models could closely follow the observed data especially during the start and the end of epidemic period. In these locations, correlation coefficients between the observed and estimated ranged between 0.55 to 0.91and the model-estimated influenza peaks were within 3 weeks from the observations. CONCLUSION: Our study demonstrated the significant link between specific humidity and influenza activity across temperate and subtropical climates, and that inclusion of meteorological parameters in the surveillance system may further our understanding of influenza transmission patterns.

Transitions between health care settings in the final three months of life in four EU countries.

BACKGROUND: Transitions between care settings may be related to poor quality in end-of-life care. Yet there is a lack of cross-national population-based data on transitions at the end of life. METHOD: International mortality follow-back study with data collection in Belgium, Netherlands, Italy and Spain (2009-11) via existing representative epidemiological surveillance networks of general practitioners (GPs). All general practitioners reported weekly, on a standardized registration form, every deceased patient (≥18 years) in their practice and identified those who died 'non-suddenly'. RESULTS: Among 4791 non-sudden deaths in Belgium, Netherlands, Italy and Spain, 59%, 55%, 60% and 58%, respectively, were transferred between care settings at least once in the final 3 months of life (10%, 8%, 10% and 13% in final 3 days of life); 10%, 5%, 8% and 12% were transferred three times or more (P < 0.001 in multivariate analyses adjusting for country differences in age, sex, cause of death, presence of dementia). In all countries, transitions were more frequent among patients residing at home (61-73%) than among patients residing in a care home (33-40%). Three months before death 5-7% of patients were in hospital, and this rose to 27-39% on the day of death. Patient wishes were cited as the reason for the last transition before death in 27%, 39%, 9% and 6% of cases in Belgium, Netherlands, Italy and Spain, respectively (P < 0.001). CONCLUSION: End-of-life transitions between health care settings are common across EU countries, in particular late hospitalizations for people residing at home. Frequency, type and reasons for terminal hospitalizations vary between countries.

Hipotiroidismo subclínico en una muestra oportunista de la población de Castilla y León / Prevalence and clinical characteristics of subclinical hypothyroidism in an opportunistic sample in the population of Castile-León (Spain)

Objetivo: Describir la distribución de los valores de la hormona estimulante del tiroides (TSH) y estimar la prevalencia de hipotiroidismo subclínico en la población adulta de Castilla y León. Material y método: Estudio observacional en 45 consultas de medicina de familia de Castilla y León seleccionadas de manera oportunista. Se determinó la TSH en sueros, recogidos por cualquier motivo, de personas ≥35 años de edad. Se realizó análisis de confirmación, incluyendo la tiroxina libre y los anticuerpos antitiroperoxidasa. Resultados: Se realizaron 3957 análisis. El 63,4% eran mujeres. La edad media fue de 61,5 años. La mediana de los valores de TSH fue de 2,3 ¿UI/mL (2, ¿UI/mL en mujeres y 2,1 ¿UI/mL en hombres), con tendencia ascendente con la edad. Los valores de TSH son mayores en los hipotiroidismos subclínicos desconocidos o sin tratamiento que en los tratados. Los valores más bajos se observan en los sujetos eutiroideos. La prevalencia de hipotiroidismo subclínico fue del 9,2% (intervalo de confianza del 95%: 8,3-10,2); en las mujeres fue el triple que en los hombres (12,4% frente a 3,7%) y aumenta con la edad, con un máximo del 16,9% en las mujeres de 45 a 64 años. Conclusiones: La prevalencia estimada de hipotiroidismo subclínico es alta, en los límites superiores reflejados en la literatura. La posibilidad de progresión a hipotiroidismo manifiesto, así como la asociación con diversas enfermedades y factores de riesgo, aconsejan una gestión adecuada de su diagnóstico y tratamiento (AU)

Objective: To describe the distribution of thyroid-stimulating hormone (TSH) values and to estimate the prevalence of subclinical hypothyroidism in the adult population of Castile and León (Spain). Method: An observational study was conducted in an opportunistic sample of 45 primary care centers in Castile and León. TSH was determined in people aged ≥35 years that attended a primary care physician and had a blood test for any reason. Confirmatory analysis included free thyroxine and anti-thyroid peroxidase antibody determination. Results: A total of 3957 analyses were carried out, 63% in women. The mean age was 61.5 years. The median TSH value was 2.3 ¿IU/mL (2.5 ¿IU/mL in women and 2.1 ¿IU/mL in men), with a rising trend with age. TSH values were higher in undiagnosed or untreated subclinical hypothyroidism than in patients under treatment. The lowest levels were found in euthyroidism. The prevalence of subclinical hypothyroidism was 9.2% (95%CI: 8.3-10.2), and hypothyroidism was three times higher in women than in men (12.4% versus 3.7%). Hypothyroidism increased with age, reaching a peak of 16.9% in women aged 45 to 64 years. Conclusions: The prevalence of subclinical hypothyroidism in our sample was high and in the upper limits of values found in previous studies. Proper diagnosis and treatment are important because of the risk of progression to hypothyroidism and the association with multiple diseases and other risk factors (AU)

[cycEVA study: case control study measuring influenza vaccine effectiveness in Spain, 2008-2013]. / Estudio cycEVA: casos y controles para la estimación de la efectividad de la vacuna antigripal en España, 2008-2013.

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.

Fundamentos: Desde 2008-09 la efectividad de la vacuna (EV) antigripal en España se estima con el estudio de casos y controles para la evaluación de la EV antigripal (cycEVA), componente español de la red europea (Influenza- Monitoring Vaccine Effectiveness (I-MOVE). El objetivo es describir la evolución del estudio cycEVAdurante las cinco temporadas del período 2008/09-2012/13. Métodos: Se analizaron los siguientes indicadores: 1) participación de los médicos/pediatras centinela (MP); 2) población y periodo de estudio, 3) calidad de los datos y 4) difusión de los resultados mediantes publicaciones. Se calculó el porcentaje anual de cambio constante de los indicadores analizándose su tendencia mediante el test de Cochran-Armitage. Resultados: El número de MP participantes aumentó de 164 en 2008-09 hasta 246 en ediciones posteriores. El porcentaje de médicos que reclutaron al menos un paciente experimentó un cambio anual significativo (PCA) del 15,33%. El porcentaje de pacientes reclutados incluidos en el análisis aumentó del 77% en 2008-09 a más del 95% en las siguientes ediciones (PCA=5,91%). El porcentaje de casos y controles participantes en cycEVA sobre el total de pacientes que contribuyeron al estudio europeo I-MOVE osciló entre el 23% en la edición piloto y 30% en la temporada 2011-12. Los resultados finales se difundieron en revistas científicas con un factor de impacto situado en el cuartil 2 y en 2010-11 y 2011-12 se publicaron resultados preliminares en revistas con un factor de impacto situado en el cuartil 1 (97 citas). Conclusiones: La experiencia del estudio cycEVA se reflejó en una mejora en la oportunidad e impacto de sus resultados, cruciales para orientar las recomendaciones anuales de vacunación antigripal (AU)

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 theAnnual Percentage Change (PCA). Results: The number of participatingMP 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 (AU)

Burden on family carers and care-related financial strain at the end of life: a cross-national population-based study.

BACKGROUND: The rising number of deaths from cancer and other life-limiting illnesses is accompanied by a growing number of family carers who provide long-lasting care, including end-of-life care. This population-based epidemiological study aimed to describe and compare in four European countries the prevalence of and factors associated with physical or emotional overburden and difficulties in covering care-related costs among family carers of people at the end of life. METHODS: A cross-national retrospective study was conducted via nationwide representative sentinel networks of general practitioners (GPs). Using a standardized form, GPs in Belgium, The Netherlands, Italy and Spain recorded information on the last 3 months of life of every deceased adult practice patient (1 January 2009-31 December 2010). Sudden deaths were excluded. RESULTS: We studied 4466 deaths. GPs judged family carers of 28% (Belgium), 30% (The Netherlands), 35% (Spain) and 71% (Italy) of patients as physically/emotionally overburdened (P < 0.001). For 8% (Spain), 14% (Belgium), 36% (The Netherlands) and 43% (Italy) patients, GPs reported difficulties in covering care-related costs (P < 0.001). Patients <85 years of age (Belgium, Italy) had higher odds of having physically/emotionally overburdened family carers and financial burden. Death from non-malignant illness (vs. cancer) (Belgium and Italy) and dying at home compared with other locations (The Netherlands and Italy) were associated with higher odds of difficulties in covering care-related costs. CONCLUSION: In all countries studied, and particularly in Italy, GPs observed a considerable extent of physical/emotional overburden as well as difficulties in covering care-related costs among family carers of people at the end of life. Implications for health- and social care policies are discussed.

Prevalence of obesity and associated cardiovascular risk: the DARIOS study.

BACKGROUND: To estimate the prevalence of overweight and obesity in the Spanish population as measured with body mass index (BMI), waist circumference (WC) and waist to height ratio (WHtR) and to determine the associated cardiovascular risk factors. METHODS: Pooled analysis with individual data from 11 studies conducted in the first decade of the 21st century. Participants aged 35-74 years were asked about the history of cardiovascular diseases, hypertension, diabetes and hypercholesterolemia. Height, weight, WC, blood pressure, glycaemia, total cholesterol, low-density and high-density lipoprotein cholesterol and coronary risk were measured. The prevalence of overweight (BMI 25-29.9 kg/m(2)), general obesity (BMI ≥ 30 kg/m(2)), suboptimal WC (≥ 80 cm and < 88 in women, ≥ 94 and < 102 in men), abdominal obesity (WC ≥88 cm ≥102 cm in women and men, respectively) and WHtR ≥0.5 was estimated, standardized for the European population. RESULTS: We included 28,743 individuals. The prevalence of overweight and suboptimal WC was 51% and 30% in men and 36% and 22% in women, respectively; general obesity was 28% in both sexes and abdominal obesity 36% in men and 55% in women. The prevalence of WHtR ≥0.5 was 89% and 77% in men and women, respectively. All cardiovascular risk factors were significantly associated with abnormal increased values of BMI, WC and WHtR. Hypertension showed the strongest association with overweight [OR = 1.99 (95% confidence interval 1.81-2.21) and OR = 2.10 (1.91-2.31)]; suboptimal WC [OR = 1.78 (1.60-1.97) and OR = 1.45 (1.26-1.66)], with general obesity [OR = 4.50 (4.02-5.04), and OR = 5.20 (4.70-5.75)] and with WHtR ≥0.5 [OR = 2.94 (2.52-3.43), and OR = 3.02 (2.66-3.42)] in men and women respectively, besides abdominal obesity in men only [OR = 3.51 (3.18-3.88)]. Diabetes showed the strongest association with abdominal obesity in women [OR = 3,86 (3,09-4,89). CONCLUSIONS: The prevalence of obesity in Spain was high. Overweight, suboptimal WC, general, abdominal obesity and WHtR ≥0.5 was significantly associated with diabetes, hypertension, hypercholesterolemia and coronary risk. The use of lower cut-off points for both BMI and particularly WC and could help to better identify the population at risk and therefore achieve more effective preventive measures.

End-of-life decisions: a cross-national study of treatment preference discussions and surrogate decision-maker appointments.

BACKGROUND: Making treatment decisions in anticipation of possible future incapacity is an important part of patient participation in end-of-life decision-making. This study estimates and compares the prevalence of GP-patient end-of-life treatment discussions and patients' appointment of surrogate decision-makers in Italy, Spain, Belgium and the Netherlands and examines associated factors. METHODS: A cross-sectional, retrospective survey was conducted with representative GP networks in four countries. GPs recorded the health and care characteristics in the last three months of life of 4,396 patients who died non-suddenly. Prevalences were estimated and logistic regressions were used to examine between country differences and country-specific associated patient and care factors. RESULTS: GP-patient discussion of treatment preferences occurred for 10%, 7%, 25% and 47% of Italian, Spanish, Belgian and of Dutch patients respectively. Furthermore, 6%, 5%, 16% and 29% of Italian, Spanish, Belgian and Dutch patients had a surrogate decision-maker. Despite some country-specific differences, previous GP-patient discussion of primary diagnosis, more frequent GP contact, GP provision of palliative care, the importance of palliative care as a treatment aim and place of death were positively associated with preference discussions or surrogate appointments. A diagnosis of dementia was negatively associated with preference discussions and surrogate appointments. CONCLUSIONS: The study revealed a higher prevalence of treatment preference discussions and surrogate appointments in the two northern compared to the two southern European countries. Factors associated with preference discussions and surrogate appointments suggest that delaying diagnosis discussions impedes anticipatory planning, whereas early preference discussions, particularly for dementia patients, and the provision of palliative care encourage participation.

Síndrome metabólico en España: prevalencia y riesgo coronario asociado a la definición armonizada y a la propuesta por la OMS. Estudio DARIOS / Metabolic syndrome in Spain: prevalence and coronary risk associated with harmonized definition and WHO proposal. DARIOS study

Introducción y objetivos. Actualizar la prevalencia del síndrome metabólico en España y su riesgo coronario asociado, empleando la definición armonizada y la nueva propuesta de la Organización Mundial de la Salud (síndrome metabólico premórbido), que excluye diabetes mellitus y enfermedad cardiovascular. Métodos. Análisis agrupado con datos individuales de 11 estudios, incluyendo a 24.670 individuos de 10 comunidades autónomas con edad 35-74 años. El riesgo coronario se estimó con la función REGICOR. Resultados. La prevalencia de síndrome metabólico fue del 31% (mujeres, 29%; intervalo de confianza del 95%, 25-33%; varones, 32%; intervalo de confianza del 95%, 29-35%). Entre los varones con síndrome metabólico, fueron más frecuentes la elevación de glucemia (p=0,019) y triglicéridos (p<0,001); por contra, entre las mujeres predominaron obesidad abdominal (p<0,001) y colesterol unido a las lipoproteínas de alta densidad bajo (p=0,001). Las personas con síndrome metabólico mostraron riesgo coronario moderado (varones, 8%; mujeres, 5%), pero mayor (p<0,001) que la población sin síndrome metabólico (varones, 4%; mujeres, 2%). El incremento de riesgo coronario asociado al síndrome metabólico fue mayor en mujeres que en varones (2,5 frente a 2 veces, respectivamente; p<0,001). La prevalencia de síndrome metabólico premórbido fue del 24% y su riesgo coronario asociado también aumentó más en las mujeres que en los varones (2 frente a 1,5; p<0,001). Conclusiones. La prevalencia de síndrome metabólico es del 31%; el síndrome metabólico premórbido la rebaja al 24% y delimita la población para prevención primaria. El incremento de riesgo coronario es proporcionalmente mayor en las mujeres, tanto en síndrome metabólico como en síndrome metabólico premórbido (AU)

Introduction and objectives. To update the prevalence of metabolic syndrome and associated coronary risk in Spain, using the harmonized definition and the new World Health Organization proposal (metabolic premorbid syndrome), which excludes diabetes mellitus and cardiovascular disease. Methods. Individual data pooled analysis study of 24 670 individuals from 10 autonomous communities aged 35 to 74 years. Coronary risk was estimated using the REGICOR function. Results.Prevalence of metabolic syndrome was 31% (women 29% [95% confidence interval, 25%-33%], men 32% [95% confidence interval, 29%-35%]). High blood glucose (P=.019) and triglycerides (P<.001) were more frequent in men with metabolic syndrome, but abdominal obesity (P<.001) and low high-density lipoprotein cholesterol (P=.001) predominated in women. Individuals with metabolic syndrome showed moderate coronary risk (8% men, 5% women), although values were higher (P<.001) than in the population without the syndrome (4% men, 2% women). Women and men with metabolic syndrome had 2.5 and 2 times higher levels of coronary risk, respectively (P<.001). Prevalence of metabolic premorbid syndrome was 24% and the increase in coronary risk was also proportionately larger in women than in men (2 vs 1.5, respectively; P<.001). Conclusions. Prevalence of metabolic syndrome is 31%; metabolic premorbid syndrome lowers this prevalence to 24% and delimits the population for primary prevention. The increase in coronary risk is proportionally larger in women, in both metabolic syndrome and metabolic premorbid syndrome (AU)
