Effect of glucose variability on the mortality of adults aged 75 years and over during the first year of the COVID-19 pandemic.

BACKGROUND: To our knowledge, only one study has examined the association between glucose variability (GV) and mortality in the elderly population with diabetes. GV was assessed by HbA1c, and a J-shaped curve was observed in the relationship between HbA1c thresholds and mortality. No study of GV was conducted during the COVID-19 pandemic and its lockdown. This study aims to evaluate whether GV is an independent predictor of all-cause mortality in patients aged 75 years or older with and without COVID-19 who were followed during the first year of the COVID-19 pandemic and its lockdown measures. METHODS: This was a retrospective cohort study of 407,492 patients from the AGED-MADRID dataset aged 83.5 (SD 5.8) years; 63.2% were women, and 29.3% had diabetes. GV was measured by the coefficient of variation of fasting plasma glucose (CV-FPG) over 6 years of follow-up (2015-2020). The outcome measure was all-cause mortality in 2020. Four models of logistic regression were performed, from simple (age, sex) to fully adjusted, to assess the effect of CV-FPG on all-cause mortality. RESULTS: During follow-up, 34,925 patients died (14,999 women and 19,926 men), with an all-cause mortality rate of 822.3 per 10,000 person-years (95% confidence interval (CI), 813.7 to 822.3) (739 per 10,000; 95% CI 728.7 to 739.0 in women and 967.1 per 10,000; 95% CI 951.7 to 967.2 in men). The highest quartile of CV-FPG was significantly more common in the deceased group (40.1% vs. 23.6%; p < 0.001). In the fully adjusted model including dementia (Alzheimer's disease) and basal FPG, the odds ratio for mortality ranged from 1.88 to 2.06 in patients with T2DM and from 2.30 to 2.61 in patients with normoglycaemia, according to different sensitivity analyses. CONCLUSIONS: GV has clear implications for clinical practice, as its assessment as a risk prediction tool should be included in the routine follow-up of the elderly and in a comprehensive geriatric assessment. Electronic health records can incorporate tools that allow its calculation, and with this information, clinicians will have a broader view of the medium- and long-term prognosis of their patients.

Peripheral Atherosclerosis in Patients With Erectile Dysfunction: A Population-Based Study.

INTRODUCTION: The presence of erectile dysfunction (ED) could be a warning of vascular disease in different arterial territories. AIM: The aim of this study was to investigate the association between ED and the presence of atherosclerosis in 2 different vascular beds: carotid and lower limbs. METHODS: A total of 614 volunteers between 45 and 74 years of age (mean age 61.0 years) were randomly selected from the general population. ED was assessed using the International Index of Erectile Function (IIEF-5). Ankle-brachial index (ABI) measurement and carotid atherosclerosis were evaluated by echo-Doppler. MAIN OUTCOME MEASURES: Mean carotid intima-media thickness (IMT), prevalence of carotid plaques, mean ABI, and prevalence of ABI < 0.9 were the main outcome measures. RESULTS: ED was present in 373 subjects (59.7%). Mean carotid IMT was significantly higher in men with ED (0.762 ± 0.151 mm vs 0.718 ± 0.114 mm, P < .001). Also the global prevalence of carotid plaques was more frequent in men with ED (63.8% vs 44.8%, P < .001), even after adjusting by age, cardiovascular risk factors, and ongoing treatment (P = .039). Both the IMT and the prevalence of carotid plaques increased significantly with ED severity (P trend .004 and <.001, respectively). There were no significant differences between groups neither in mean ABI nor in the prevalence of subjects with ABI < 0.9. However, there was a trend to a lower ABI and a higher prevalence of ABI < 0.9 with increasing ED severity. CONCLUSION: In the general population, the presence of ED identifies subjects with higher atherosclerosis burden in carotid arteries but not in the lower extremities.

Common mental disorders in primary health care: differences between Latin American-born and Spanish-born residents in Madrid, Spain.

PURPOSE: Our main objective was to estimate and compare the prevalence of the most common mental disorders between Latin American-born and Spanish-born patients in Madrid, Spain. We also analyzed sociodemographic factors associated with these disorders and the role of the length of residency for Latin American-born patients. METHODS: We performed a cross-sectional study to compare Latin American-born (n = 691) and Spanish-born outpatients (n = 903) from 15 primary health care centers in Madrid, Spain. The Primary Care Evaluation of Mental Disorders was used to diagnose common mental disorders. Sociodemographic, psychosocial, and migration data were collected. RESULTS: We detected common mental disorders in 49.9 % (95 % CI = 47.4-52.3 %) of the total sample. Values were higher in Latin American-born patients than in Spanish-born patients for any disorder (57.8 % vs. 43.9 %, p < 0.001), mood disorders (40.1 % vs. 34.8 %, p = 0.030), anxiety disorders (20.5 % vs. 15.3 %, p = 0.006), and somatoform disorders (18.1 % vs. 6.6 %, p < 0.001). There were no statistically significant differences in prevalence between Latin American-born patients with less than 5 years of residency and Latin American-born residents with 5 or more years of residency. Finally, multivariate analysis shows that gender, having/not having children, monthly income, geographic origin, and social support were significantly associated with several disorders. LIMITATIONS: The sample was neither population-based nor representative of the general immigrant or autochthonous populations. CONCLUSIONS: The study provides further evidence of the high prevalence of common mental disorders in Latin American-born patients in Spain compared with Spanish-born patients.

Psychometric properties of the eight-item modified Medical Outcomes Study Social Support Survey based on Spanish outpatients.

PURPOSE: The aim of this study was to examine the psychometric properties of the modified Medical Outcomes Study Social Support Survey (mMOS-SS) in a primary healthcare setting (PHCS). METHODS: A cross-sectional descriptive study was carried out with Spanish outpatients (N = 903) from a PHCS. Subjects responded to the first eight items of the classic Medical Outcomes Study-Social Support Survey (MOS-SS), in effect the mMOS-SS, and immediately proceeded to give answers to the rest of the scale. Also, sociodemographic, self-reported health status and mood/anxiety disorders data were collected. Factor structure was analyzed using exploratory and confirmatory analysis, internal reliability was determined by Cronbach's standardized alpha, and consistency was evaluated by item-to-total score correlations. Evidences of validity were assessed by Spearman's rank correlations, and using the Mann-Whitney test or Kruskal-Wallis test as appropriate, of differences between the mMOS-SS and the MOS-SS. RESULTS: Mean scores for the MOS-SS (mean = 4.26, SD = 0.78) and mMOS-SS (mean = 4.34, SD = 0.74) are similar. Cronbach's alpha was 0.96 and 0.91, for the MOS-SS and mMOS-SS, respectively. Item-to-total score correlations of the MOS-SS and mMOS-SS are ≥0.64 and ≥0.70, respectively. Exploratory factor analysis (EFA) [56.63% variance, KMO=0.904; χ2=4396.27], and confirmatory factor analysis (CFA) [CFI=0.95; NNFI(TLI)=0.97; SRMR=0.05; χ2=296.81; RMSEA=0.17] showed a one-factor structure. CONCLUSIONS: Psychometric properties of the Spanish version of the mMOS-SS in outpatients attending a PHCS are adequate. Factor analysis confirmed a one-factor model with acceptable fit indices.

[HDL-cholesterol concentration and risk of SARS-CoV-2 infection in people over 75 years of age: a cohort with half a million participants from the Community of Madrid]. / Concentración de colesterol-HDL y riesgo de infección por SARS-CoV-2 en personas mayores de 75 años: una cohorte con medio millón de participantes de la Comunidad de Madrid.

OBJECTIVE: The aim of this study was to analyze the relationship between HDL-cholesterol and the risk of SARS-CoV-2 infection in over 75-year-olds residing in the Community of Madrid. METHODS: Study of a population-based cohort, composed of all residents in Madrid (Spain) born before January 1, 1945 and alive on December 31, 2019. Demographic, clinical and analytical data were obtained from primary care electronic medical records from January 2015. Confirmed SARS-CoV-2 infection was defined as a positive RT-PCR or antigen test result. Infection data correspond to the period March 1, 2020 through December 31, 2020. RESULTS: Of the 593,342 cohort participants, 501,813 had at least one HDL-cholesterol determination in the past 5 years. Their mean age was 83.4±5.6 years and 62.4% were women. A total of 36,996 (7.4%) had a confirmed SARS-CoV2 infection during 2020. The risk of infection [odds ratio (95% confidence interval)] for SARS-CoV2 according to increasing quintiles of HDL-cholesterol was 1, 0.960 (0.915-1.007), 0.891 (0.848-0.935), 0.865 (0.824-0.909) and 0.833 (0.792-0.876), after adjusting for age, sex, cardiovascular risk factors and comorbidities. CONCLUSIONS: There is an inverse and dose-dependent relationship between HDL-cholesterol concentration and the risk of SARS-CoV2 infection in subjects aged over 75 years of age in the Community of Madrid.

Validation of diagnosis of acute myocardial infarction and stroke in electronic medical records: a primary care cross-sectional study in Madrid, Spain (the e-MADVEVA Study).

OBJECTIVES: To validate the diagnoses of acute myocardial infarction (AMI) and stroke recorded in electronic medical records (EMR) and to estimate the population prevalence of both diseases in people aged ≥18 years. DESIGN: Cross-sectional validation study. SETTING: 45 primary care centres. PARTICIPANTS: Simple random sampling of diagnoses of AMI and stroke (International Classification of Primary Care-2 codes K75 and K90, respectively) registered by 55 physicians and random age-matched and sex-matched sampling of the records that included in primary care EMRs in Madrid (Spain). PRIMARY AND SECONDARY OUTCOME MEASURES: Sensitivity, specificity, positive and negative predictive values and overall agreement were calculated using the kappa statistic. Applied gold standards were ECGs, brain imaging studies, hospital discharge reports, cardiology reports and neurology reports. In the case of AMI, the ESC/ACCF/AHA/WHF Expert Consensus Document was also used. Secondary outcomes were the estimated prevalence of both diseases considering the sensitivity and specificity obtained (true prevalence). RESULTS: The sensitivity of a diagnosis of AMI was 98.11% (95% CI, 96.29 to 99.03), and the specificity was 97.42% (95% CI, 95.44 to 98.55). The sensitivity of a diagnosis of stroke was 97.56% (95% CI, 95.56 to 98.68), and the specificity was 94.51% (95% CI, 91.96 to 96.28). No differences in the results were found after stratification by age and sex (both diseases). The prevalence of AMI and stroke was 1.38% and 1.27%, respectively. CONCLUSION: The validation results show that diagnoses of AMI and stroke in primary care EMRs constitute a helpful tool in epidemiological studies. The prevalence of AMI and stroke was lower than 2% in the population aged over 18 years.

Effect of depression on mortality and cardiovascular morbidity in type 2 diabetes mellitus after 3 years follow up. The DIADEMA study protocol.

BACKGROUND: Type 2 diabetes mellitus and depression are highly prevalent diseases that are associated with an increased risk of cardiovascular disease and mortality. There is evidence about a bidirectional association between depressive symptoms and type 2 diabetes mellitus. However, prognostic implications of the joint effects of these two diseases on cardiovascular morbidity and mortality are not well-known. METHOD/DESIGN: A three-year, observational, prospective, cohort study, carried out in Primary Health Care Centres in Madrid (Spain). The project aims to analyze the effect of depression on cardiovascular events, all-cause and cardiovascular mortality in patients with type 2 diabetes mellitus, and to estimate a clinical predictive model of depression in these patients.The number of patients required is 3255, all them with type 2 diabetes mellitus, older than 18 years, who regularly visit their Primary Health Care Centres and agree to participate. They are chosen by simple random sampling from the list of patients with type 2 diabetes mellitus of each general practitioner.The main outcome measures are all-cause and cardiovascular mortality and cardiovascular morbidity; and exposure variable is the major depressive disorder.There will be a comparison between depressed and not depressed patients in all-cause mortality, cardiovascular mortality, coronary artery disease and stroke using the Chi-squared test. Logistic regression with random effects will be used to adjust for prognostic factors. Confounding factors that might alter the effect recorded will be taken into account in this analysis. To assess the effect of depression on the mortality, a survival analysis will be used comparing the two groups using the log-rank test. The control of potential confounding variables will be performed by the construction of a Cox regression model. DISCUSSION: Our study's main contribution is to evaluate the increase in the risk of cardiovascular morbidity and mortality, in depressed Spanish adults with type 2 diabetes mellitus attended in Primary Health Care Setting. It would also be useful to identify subgroups of patients for which the interventions could be more beneficial.

Pre-infection HDL-cholesterol levels and mortality among elderly patients infected with SARS-CoV-2.

BACKGROUND AND AIMS: Low HDL-cholesterol (HDLc) concentration is associated with a greater risk of infection-related mortality. We wanted to evaluate the relationship between pre-infection HDLc levels and mortality among older patients infected with SARS-Cov-2. METHODS: This is a population-based, cohort study, comprising all individuals residing in Madrid (Spain) born before 1 January 1945, and alive on 31 December 2019. Demographic, clinical, and analytical data were obtained from the primary care electronic clinical records. Confirmed SARS-CoV-2 infection was defined as a positive result in the RT-qPCR or in the antigen test. A death from COVID-19 was defined as that registered in the hospital chart, or as any death occurring in the 15 days following a confirmed SARS-CoV-2 infection. Data on infection, hospitalization, or death due to SAR-CoV-2 were collected from 1 March 2020 through 31 December 2020. RESULTS: Of the 593,342 individuals comprising the cohort, 36,966 had a SARS-CoV-2 infection during 2020, and at least one HDLc measurement in the previous five years. Among them, 9689 (26.2%) died from COVID-19. After adjustment for age and sex, the relative risk (95% confidence interval) of COVID-19 death across increasing quintiles of HDLc was 1.000, 0.896 (0.855-0.940), 0.816 (0.776-0.860), 0.758 (0.719-0.799), and 0.747 (0.708-0.787). The association was maintained after further adjustment for comorbidities, statin treatment and markers of malnutrition. While in females this association was linear, in males it showed a U-shaped curve. CONCLUSIONS: In older subjects, a higher HDLc measured before SARS-CoV-2 infection was associated with a lower risk of death.

Glycemic variability and all-cause mortality in a large prospective southern European cohort of patients with differences in glycemic status.

BACKGROUND: Few studies have analyzed the relationship between glucose variability (GV) and adverse health outcomes in patients with differences in glycemic status. The present study tests the hypothesis that GV predicts all-cause mortality regardless of glycemic status after simple adjustment (age and sex) and full adjustment (age, sex, cardiovascular disease, hypertension, use of aspirin, statins, GLP-1 receptor agonists, SGLT-2 inhibitors and DPP-4 inhibitors, baseline FPG and average HbA1c). METHODS: Prospective cohort study with 795 normoglycemic patients, 233 patients with prediabetes, and 4,102 patients with type 2 diabetes. GV was measured using the coefficient of variation of fasting plasma glucose (CV-FPG) over 12 years of follow-up. The outcome measure was all-cause mortality. RESULTS: A total of 1,223 patients (657 men, 566 women) died after a median of 9.8 years of follow-up, with an all-cause mortality rate of 23.35/1,000 person-years. In prediabetes or T2DM patients, the fourth quartile of CV-FPG exerted a significant effect on all-cause mortality after simple and full adjustment. A sensitivity analysis excluding participants who died during the first year of follow-up revealed the following results for the highest quartile in the fully adjusted model: overall, HR (95%CI) = 1.54 (1.26-1.89); dysglycemia (prediabetes and T2DM), HR = 1.41 (1.15-1.73); T2DM, HR = 1.36 (1.10-1.67). CONCLUSION: We found CV-FPG to be useful for measurement of GV. It could also be used for the prognostic stratification of patients with dysglycemia.

Validation of diabetes mellitus and hypertension diagnosis in computerized medical records in primary health care.

BACKGROUND: Computerized Clinical Records, which are incorporated in primary health care practice, have great potential for research. In order to use this information, data quality and reliability must be assessed to prevent compromising the validity of the results.The aim of this study is to validate the diagnosis of hypertension and diabetes mellitus in the computerized clinical records of primary health care, taking the diagnosis criteria established in the most prominently used clinical guidelines as the gold standard against which what measure the sensitivity, specificity, and determine the predictive values.The gold standard for diabetes mellitus was the diagnostic criteria established in 2003 American Diabetes Association Consensus Statement for diabetic subjects. The gold standard for hypertension was the diagnostic criteria established in the Joint National Committee published in 2003. METHODS: A cross-sectional multicentre validation study of diabetes mellitus and hypertension diagnoses in computerized clinical records of primary health care was carried out. Diagnostic criteria from the most prominently clinical practice guidelines were considered for standard reference.Sensitivity, specificity, positive and negative predictive values, and global agreement (with kappa index), were calculated. Results were shown overall and stratified by sex and age groups. RESULTS: The agreement for diabetes mellitus with the reference standard as determined by the guideline was almost perfect (κ=0.990), with a sensitivity of 99.53%, a specificity of 99.49%, a positive predictive value of 91.23% and a negative predictive value of 99.98%.Hypertension diagnosis showed substantial agreement with the reference standard as determined by the guideline (κ=0.778), the sensitivity was 85.22%, the specificity 96.95%, the positive predictive value 85.24%, and the negative predictive value was 96.95%. Sensitivity results were worse in patients who also had diabetes and in those aged 70 years or over. CONCLUSIONS: Our results substantiate the validity of using diagnoses of diabetes and hypertension found within the computerized clinical records for epidemiologic studies.

Effectiveness of PRECEDE model for health education on changes and level of control of HbA1c, blood pressure, lipids, and body mass index in patients with type 2 diabetes mellitus.

BACKGROUND: Individual health education is considered to be essential in the overall care of patients with type 2 diabetes (DM2), although there is some uncertainty regarding its metabolic control benefits. There have been very few randomized studies on the effects of individual education on normal care in DM2 patients with a control group, and none of these have assessed the long-term results. Therefore, this study aims to use this design to assess the effectiveness of the PRECEDE (Predisposing, Reinforcing, Enabling, Causes in Educational Diagnosis, and Evaluation) education model in the metabolic control and the reduction of cardiovascular risk factors, in patients with type 2 diabetes. METHODS: An open community effectiveness study was carried out in 8 urban community health centers in the North-East Madrid Urban Area (Spain). Six hundred patients with DM2 were randomized in two groups: PRECEDE or conventional model for health promotion education. The main outcome measures were glycated hemoglobin A1c, body mass index (BMI), blood pressure, lipids and control criteria during the 2-year follow-up period. RESULTS: Glycated hemoglobin A1c and systolic blood pressure (SBP) levels decreased significantly in the PRECEDE group (multivariate analysis of covariance, with baseline glycated hemoglobin A1c, SBP, and variables showing statistically significant differences between groups at baseline visits). The decrease levels in diastolic blood pressure (DBP), triglycerides and LDL cholesterol were nonsignificant. PRECEDE increased compliance in all control criteria, except for LDL cholesterol. BMI did not change during the study in either of the two models analyzed. CONCLUSIONS: PRECEDE health education model is a useful method in the overall treatment in patients with type 2 diabetes, which contributes to decrease glycated hemoglobin A1c and SBP levels and increase the compliance in all the control criteria, except for LDL cholesterol.

The relationship between social support and self-reported health status in immigrants: an adjusted analysis in the Madrid Cross Sectional Study.

BACKGROUND: Social support is an important factor in the adaptation process of immigrants, helping for their integration in a new environment. The lack of social support may influence on well-being and health status. The aim of this study is to describe the social support of immigrant and native population and study the possible association between immigration and lack social support after adjusting for sociodemographic factors, income, stress and self-reported health status. METHODS: Cross-sectional population based study of immigrants and national patients without mental disorders of 15 urban primary health centers in the north-eastern area of Madrid. Participants provided information on social support, stress level, perceived health status and socio-economic characteristics. Descriptive and multiple logistic regression were conducted. RESULTS: The proportion of the global perception of social support among immigrants and natives was 79.2% and 94.2%, respectively. The lack of global social support adjusted prevalence ratio (PR) of immigrant was 2.72 (95% Confidence Interval=1.81-4.09), showing a significant association with being male (PR=2.26), having monthly income below 500 euros (PR=3.81) and suffering stress (PR=1.94). For the dimensions of lack of social support the higher association was being an immigrant and suffering stress. CONCLUSIONS: We conclude that with regardless of the level of monthly income, stress level, self-reported health status, and gender, immigrant status is directly associated with lack social support. The variable most strongly associated with lack social support has been monthly income below 500 euros.

Phenotype of haptoglobin and presence of subclinical vascular disease: Population study. / Fenotipo de la haptoglobina y presencia de enfermedad vascular subclínica: estudio poblacional.

INTRODUCTION AND OBJECTIVES: Haptoglobin is a protein involved in the protection against oxidative damage caused by iron in haemoglobin. This protein is polymorphic, with 3 isomorphs prevalent in the population. The carriers of the Hp2-2 isoform have a lower antioxidant capacity and, in the population with diabetes, an increased risk of subclinical vascular disease and cardiovascular complications. The objective of this study was to evaluate whether this isomorphy is associated with an increased risk of carotid arteriosclerosis in subjects with and without diabetes, and free of cardiovascular disease. PATIENTS AND METHODS: A study was conducted in a population between 45 and 74years of age, randomly selected from the northwest area of Madrid. The participants were characterised in terms of their glycaemic status by oral glucose overload and the determination of the concentration of Hb1Ac. The haptoglobin phenotypes in all of them were determined by means of an immunoenzymatic assay, and the presence of carotid arteriosclerosis by ultrasound. RESULTS: Of the 1,256 participants included in the present analysis (mean age 61.6±6years, 41.8% males), the distribution of the isoforms of haptoglobin was as follows: Hp1-1: 13.3%, Hp1-2: 48.5%, and Hp2-2: 38.2%. In comparison with subjects Hp1-1 and Hp1-2, those with the Hp2-2 phenotype had a higher prevalence of dyslipidaemia (53.3% vs 43%; P<.0001) and arterial hypertension (39.2% vs. 32.2%, P=.012), and they more frequently received treatment with statins (31.5% vs 21.6%, P<.0001), and with antihypertensive agents (38.4% vs 30.8%, P=.006). The carriers of the Hp2-2 isoform had a higher prevalence of carotid plaques (OR: 1.35, 95%CI: 1.07-1.69, P=.011), with no differences in that prevalence as regards the glycaemic status. There were no differences in the intima-media thickness between the different phenotypes. The relationship of the Hp2-2 phenotype with the presence of plaques in the carotid was independent of age, gender, presence of risk factors (dyslipidaemia, hypertension and diabetes), the concentration of LDL-cholesterol, C-reactive protein and uric acid, blood pressure, and treatment with statins, and hypertensive drugs (OR: 1.31, 95%CI 1.01-1.70, P=.044). CONCLUSION: Subjects with the Hp2-2 phenotype of haptoglobin have a higher prevalence of carotid arteriosclerosis, which is independent of the presence of other cardiovascular risk factors and their glycaemic status.

Cardiovascular disease in nonagenarians: Prevalence and utilization of preventive therapies.

AIMS: Nonagenarians are a fast growing segment of industrialized countries' populations. Despite a greater risk of cardiovascular disease, there are limited data about their use of preventive therapies and factors guiding decisions regarding their prescription. The aim of this study was to evaluate the prevalence of cardiovascular diseases and the patterns of use of cardiovascular treatments in subjects ≥90 years old. METHODS: Population-based, cross-sectional study, in all nonagenarians residing in the Community of Madrid (Spain). Data were obtained from their electronic clinical records in primary care. RESULTS: Data were available from 59,423 subjects (mean age 93.3 years, 74.2% female, 13.5% with dementia). Prevalence of cardiovascular disease was 24.1% (10.9% with coronary artery disease (CAD), 13.1% with cerebrovascular disease (CVD) and 2.7% with peripheral artery disease(PAD)). In primary prevention, the use of statins and antiplatelet agents was 21.9% and 26.7%, respectively. Of subjects with vascular disease 27.7% were receiving a combined preventive strategy (use of antithrombotics, plus statins, plus blood pressure below 140/90 mmHg). Factors favourably associated with a combined preventive strategy were: female sex (odds ratio (OR) 1.29; 95% confidence interval (CI): 1.11-1.49), being independent versus totally dependent (OR 1.94; 95% CI: 1.43-2.65), diabetes (OR 1.42; 95% CI: 1.20-1.68), and negatively, age (OR 0.87; 95% CI: 0.85-0.90), CVD versus CAD (OR 0.41; 95% CI: 0.35-0.47), PAD versus CAD (OR 0.23; 95% CI: 0.18-0.30), dementia (OR 0.61; 95% CI: 0.49-0.76) and nursing home residency (OR 0.73; 95% CI: 0.57-0.93). CONCLUSION: Nonagenarians have a great burden of cardiovascular diseases and receive a great number of preventive therapies, even in primary prevention, despite their unproven efficacy at these ages.

Prevalence of atrial fibrillation and associated anticoagulant therapy in the nonagenarian population of the Community of Madrid, Spain.

AIMS: The objective of the present study was to evaluate the prevalence of atrial fibrillation (AF) in nonagenarians living in the Community of Madrid, their clinical features, the use of anticoagulant therapy and factors associated with its use. METHODS: This was a cross-sectional study of 59 423 individuals aged ≥90 years, living in the Community of Madrid on 31 December 2015. Clinical information was obtained from a database that includes information from electronic medical records collected by 3881 general practitioners in primary care. RESULTS: Some 16.95% of nonagenarians (n = 10 077) were diagnosed with atrial fibrillation. These individuals have a higher prevalence of classic risk factors and established cardiovascular disease, as well as higher comorbidity. Of these, 67.6% received anticoagulant therapy, 27.9% received antiplatelet agents and 7.2% received both treatments simultaneously. Of the participants administered anticoagulation, 11.6% received a direct oral anticoagulant. The use of anticoagulant therapy was associated with a younger age, the presence of heart failure or venous thromboembolism, the absence of hypertension, a higher Barthel Index score, a greater number of prescribed drugs, a higher body mass index and a lower Charlson Comorbidity Index score. CONCLUSIONS: Nonagenarians with atrial fibrillation have a high risk of stroke; however, high comorbidity and functional impairment have limited the use of anticoagulant therapy.

Risk factors associated with the carotid intima-media thickness and plaques: ESPREDIA Study. / Factores de riesgo asociados con el grosor íntima-media y la presencia de placas en arteria carótida: Estudio ESPREDIA.

OBJECTIVE: To evaluate whether there were any differences in the risk factor profile associated with either the intima-media thickness (IMT) or the presence of carotid plaques. METHODS: Cross-sectional study in 1475 subjects between 45 and 75years, randomly selected from the population of the Northwest area of Madrid (Spain). They had a physical exam, blood analysis, and ultrasound measurement of the IMT and of the presence of plaques. RESULTS: Mean IMT was 0.725±0.132mm. Forty seven percent of the participants had carotid plaques. In multivariate analysis, factors directly associated with the IMT were, age (ß0.227, P<.0001), sex (ß0.104, P<.0001), presence of hypertension (ß0.082, P=.002), diabetes (ß0.130, P<.0001) and current smoking (ß0.107, P<.0001), systolic blood pressure (SBP) (ß0.219, P<.0001) and LDL-cholesterol levels (ß0.074, P=.003), and inversely, diastolic blood pressure (DBP) (ß-0.124, P=.001), HDL-cholesterol (ß-0.111, P<.0001) and triglyceride levels (ß-0.060, P=.028). The presence of plaques was directly associated with age (OR1.08; 95%CI: 1.05-1.10), sex (OR1.95; 95%CI: 1.52-2.51), current smoking (OR2.75; 95%CI: 1.92-3.95), history of hypertension (OR1.58; 95%CI: 1.22-2.04) or diabetes (OR1.84; 95%CI: 1.31-2.58), statin treatment (OR1.56; 95%CI: 1.19-2.04) and SBP (OR1.03; 95%CI: 1.02-1.05), and inversely with DBP (OR0.98; 95%CI: 0.96-0.99). CONCLUSION: Factors associated with the IMT and the presence of plaques are similar, a finding that support a continuum between muscular layer hypertrophy and arteriosclerosis development.

Relationship of the Adherence to a Mediterranean Diet and Its Main Components with CRP Levels in the Spanish Population.

Background: Adherence to a Mediterranean diet seems to be inversely associated with C-reactive protein (CRP) concentration. A 14-point Mediterranean Diet Adherence Screener (MEDAS) has been developed to assess dietary compliance. Objective: The aim of this study was to assess whether each of the MEDAS questions as well as their final score were associated with the levels of CRP in general Spanish population. METHODS: Cross-sectional analysis of 1411 subjects (mean age 61 years, 43.0% males) randomly selected from the general population. CRP levels were determined by a commercial ELISA kit. Adherence to the Mediterranean diet was measured by the 14-point MEDAS. Results: There was an inverse correlation between adherence to the Mediterranean diet and the CRP concentration, even after adjusting by age, gender, hypertension, metabolic syndrome, body mass index, statin treatment and hypertension treatment (p = 0.041). Subjects who consume ≥2 servings of vegetables per day (p = 0.003), ≥3 pieces of fruit per day (p = 0.003), ≥1 serving of butter, margarine, or cream per day (p = 0.041) or ≥3 servings of fish/seafood per week (p = 0.058) had significantly lower levels of CRP. Conclusions: Adherence to a Mediterranean-type diet measured by a simple questionnaire is associated with lower CRP concentration. However, this association seems to be particularly related to a higher consumption of vegetables, fruits, dairy products, and fish.
