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.

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.

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.

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.

Health and wellbeing status of the long-lived individuals of the Spanish LONGECYL cross-sectional study.

BACKGROUND: The increase in life expectancy and long-lived individuals is a challenge for public health and provides an opportunity to understand the determinants of longevity. However, few studies have addressed the factors associated with the health status and quality of life in a long-lived individual population. We described the perceived health, clinical status, quality of life, and dependency for activities of daily living in a representative population in Castile and Leon, Spain. METHODS: A sample of 759 long-lived individuals aged 95 years and older was studied by the Health Sentinel Network of Castile and Leon (Spain) through a health examination and a structured questionnaire covering quality of life (EQ-5D-3), lifestyle habits, diet, working life and family health. A blood sample was taken for the study of biological and genetic markers. Chi Square and logistic regression OR with 95% confidence intervals were used to analyze the determinants of the long-lived individuals' health status. The significant level for the bivariate analysis was established at 0.05. RESULTS: Perceived health was good, very good or excellent in 64.2%, while only 46.0% had a quality-of-life index above 0.5 (ranging from 0 to 1) and 44.1% maintained acceptable independence for activities of daily living. Quality-of-life index was higher in the oldest, (OR 7.98 [2,32-27.41]) above 100 years compared to those under 98, and men had better values for independence than women (OR 2.43 [1.40-4.29]). Cardiovascular diseases were the most prevalent (85.5%), but neurological and mental diseases and vision problems had the highest impact on quality of life and independence. CONCLUSION: The long-lived individuals of Castile and Leon have a relatively well-preserved health status, although the perception of health is higher than that describing their quality of life and dependence. The quality of life was higher in the oldest age group and showed differences according to sex, with a better quality of life in men. Public health policies and programs should take in account the differences by sex and age as well as the prevention and control of the main conditions related with poor quality of life or dependence. Future research must include the interaction among genetic, socioeconomic, environmental, and other clinical factors in the quality of life and disability of long-lived individuals.

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 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.

[Influenza surveillance by molecular diagnosis]. / Vigilancia de la gripe mediante diagnóstico molecular.

INTRODUCTION: Our objective was to evaluate the application of molecular techniques in the surveillance of influenza, and to describe clinical and epidemiological characteristics of cases diagnosed in 2007-2008 and 2008-2009 seasons. METHODS: We analyzed 183 pharyngeal swabs from the same number of patients referred to the virology laboratory of the Sentinel Physician Network of Castilla y Leon, the study of influenza viruses by shell-vial technique and RT-PCR capable of detecting multiple Simultaneously, influenza virus A, B, C, respiratory syncytial virus A, B and adenovirus. RESULTS: Using cell culture were isolated 17 influenza A viruses and 19 influenza B viruses (19.7% of total). By multiple RT-PCR, was detected 49 influenza A virus, 29 influenza B virus, an influenza virus C, 3 syncytial virus type A and other B and 6 adenoviruses (44.3% of total). All influenza viruses isolated in cell culture was detected by RT-PCR. RT-PCR by 5 co-infections were detected, which represented a 6.25% of co-infections on the whole of positive samples. The average age of patients was 29 years (SD = 21.07). The proportion of women and men accounted for 43.7% and 56.3% respectively. The number of cases diagnosed in relation to age follows a pattern of negative linear correlation. CONCLUSIONS: RT-PCR is revealed as an useful tool for epidemiological surveillance of influenza, allowing also to detect viral subtypes along with other viruses involved in respiratory infections.

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

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.

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. Geriatr Gerontol Int 2017; 17: 1667-1676.

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.

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

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 µIU/mL (2.5 µIU/mL in women and 2.1 µIU/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.

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.

[Hormonal replacement therapy in Spain]. / Tratamiento hormonal sustitutivo en España. Un estudio de utilización.

BACKGROUND: The consumption of hormonal replacement therapy (HRT) in Spain is not known. Therefore, we have conducted a study to know the mean features of that consumption and to find out the prevalence of use among women older than 40. SUBJECTS AND METHOD: To know the consumption, we have used the information contained in ECOM database from the Ministry of Health regarding medicines sold to the Spanish Health System. Also, data gathered by the General Practitioner Sentinel Network of Castilla y León had been used. The data of consumption are presented in daily defined dose per 1000 women more than 40 years (DHD); prevalence of use per year and for ages was also estimated. RESULTS: The HRT consumption in Spain throughout the National Health System was 6,94 DHD in 1989 and 39.92 DHD in 1999. The percentage of women using this therapy was 0.7% in 1989 and 3,4 in 1999; the group 50-54 years had the highest prevalence of use, 10,84% (IC 95%, 10.66-11.01). CONCLUSIONS: The release into the market of those transdermal forms of HRT facilitated an increase in the consumption. Nonetheless, the proportion of postmenopausal women on HRT in Spain is lower than that of the other countries from the European Union. The proportion of women treated with estrogens and progestins is also small compared with current recommendations.

[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.

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.

Metabolic syndrome in Spain: prevalence and coronary risk associated with harmonized definition and WHO proposal. DARIOS study.

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.

[Risk factor treatment and control in relation to coronary disease risk in the Spanish population of the DARIOS Study]. / Tratamiento y control de los factores de riesgo según el riesgo coronario en la población española del estudio DARIOS.

INTRODUCTION AND OBJECTIVES: The treatment and control of cardiovascular risk factors both play key roles in primary prevention. The aim of the present study is to analyze the proportion of primary prevention patients aged 35-74 years being treated and controlled in relation to their level of coronary risk. METHODS: Pooled analysis with individual data from 11 studies conducted in the first decade of the 21st century. We used standardized questionnaires and blood pressure measures, glycohemoglobin and lipid profiles. We defined optimal risk factor control as blood pressure < 140/90 mm Hg and glycohemoglobin <7%. In hypercholesterolemia, we applied both the European Societies and Health Prevention and Promotion Activities Programme criteria. RESULTS: We enrolled 27 903 participants (54% women). Drug treatments were being administered to 68% of men and 73% of women with a history of hypertension (P<.001), 66% and 69% respectively, of patients with diabetes (P=.03), and 39% and 42% respectively, of those with hypercholesterolemia (P<.001). Control was good in 34% of men and 42% of women with hypertension (P<.001); 65% and 63% respectively, of those with diabetes (P=.626); 2% and 3% respectively, of patients with hypercholesterolemia according to European Societies criteria (P=.092) and 46% and 52% respectively, of those with hypercholesterolemia according to Health Prevention and Promotion Activities Programme criteria (P<.001). The proportion of uncontrolled participants increased with coronary risk (P<.001), except in men with diabetes. Lipid-lowering treatments were more often administered to women with ≥ 10% coronary risk than to men (59% vs. 50%, P = 0,024). [corrected] CONCLUSIONS: The proportion of well-controlled participants was 65% at best. The European Societies criteria for hypercholesterolemia were vaguely reached. Lipid-lowering treatment is not prioritized in patients at high coronary risk.
