Referable Diabetic Retinopathy Prediction Algorithm Applied to a Population of 120,389 Type 2 Diabetics over 11 Years Follow-Up.

(1) Background: Although DR screening is effective, one of its most significant problems is a lack of attendance. The aim of the present study was to demonstrate the effectiveness of our algorithm in predicting the development of any type of DR and referable DR. (2) Methods: A retrospective study with an 11-year follow-up of a population of 120,389 T2DM patients was undertaken. (3) Results: Applying the results of the algorithm showed an AUC of 0.93 (95% CI, 0.92-0.94) for any DR and 0.90 (95% CI, 0.89-0.91) for referable DR. Therefore, we achieved a promising level of agreement when applying our algorithm. (4) Conclusions: The algorithm is useful for predicting which patients may develop referable forms of DR and also any type of DR. This would allow a personalized screening plan to be drawn up for each patient.

Effect of Lipids on Diabetic Retinopathy in a Large Cohort of Diabetic Patients after 10 Years of Follow-Up.

(1) Background: Diabetic retinopathy (DR) remains the leading cause of low vision and blindness in young adults of working age. Although the most important risk factors-such as the duration of diabetes mellitus (DM) and glycemic control measured by HbA1c-are known, the effects of lipids are not as clear. The aim of the present study is to analyze the effects of lipids on the development of DR. (2) Methods: This is a retrospective study of a population of 175,645 DM2 patients, during the period 2010 to 2020, in which the effects of different lipid factors are studied. (3) Results: The variables that most influenced the development of DR in our study, based on significance and cumulative hazard (CH), were arterial hypertension (CH 1.217, p < 0.001), HbA1c levels (CH 1.162, p = 0.001), microalbuminuria (CH 1.012, p < 0.001), LDL-C cholesterol (CH 1.007, p = 0.012), TC/HDL-C index (CH 1.092, p < 0.001), No-HDL-C/HDL-C index (CH 1.065, p = 0.002), the use of statins (CH 1.001, p = 0.005), and body mass index (CH 1.007, p < 0.001). (4) Conclusions: LDL-cholesterol, TC/HDL-C, and No-HDL-C/HDL-C indices are related to the development of DR, and there is a protective effect of HDL-cholesterol and the use of fibrates.

Silent brain infarcts, peripheral vascular disease and the risk of cardiovascular events in patients with hypertension.

BACKGROUND AND AIMS: We aimed to study the relationship between cerebral small vessel disease (cSVD) lesions, as markers of subclinical target organ damage (TOD) in the brain, and incident cardiovascular events (CVE). METHODS: Data from the ISSYS (Investigating Silent Strokes in hYpertensives Study), which is a longitudinal and observational study conducted in patients with hypertension aged 50-70 years, and stroke-free at the inclusion. At the baseline visit, participants underwent a clinical interview, a brain MRI, urine and blood sampling collection and vascular testing studies. Therefore, we obtained markers of TOD from the brain [white matter hyperintensities, silent brain infarcts (SBI), cerebral microbleeds and enlarged perivascular spaces (EPVS)], from kidney (microalbuminuria, glomerular filtration) and regarding large vessels [ankle-to-brachial index (ABI), carotid-femoral pulse wave velocity]. Survival analyses were used to assess the relationship between these predictors and the incidence of cardiovascular events (CVE). RESULTS: We followed-up 964 individuals within a median time of 5 years (4.7-5), representing 4377.1 persons-year. We found 73 patients presenting incident CVE, which corresponds to a rate of 8.2%. We found ABI less than 0.9 [hazard ratio, 2.2; 95% confidence interval (CI) 1.17-4.13, P value = 0.014] and SBI (hazard ratio, 2.9; 95% CI 1.47-5.58, P value = 0.002) independently associated with higher risk of incident CVE. The inclusion of both variables in a clinical model resulted in an increased discrimination of individuals with new CVE of 4.72%, according to the integrated discrimination index. CONCLUSION: Assessment of SBI and ABI less than 0.9 may refine the cardiovascular risk stratification in patients with hypertension.

The GenoDiabMar Registry: A Collaborative Research Platform of Type 2 Diabetes Patients.

The GenoDiabMar registry is a prospective study that aims to provide data on demographic, biochemical, and clinical changes in type 2 diabetic (T2D) patients attending real medical outpatient consultations. This registry is also used to find new biomarkers related to the micro- and macrovascular complications of T2D, with a particular focus on diabetic nephropathy. With this purpose, longitudinal serum and urine samples, DNA banking, and data on 227 metabolomics profiles, 77 immunoglobulin G glycomics traits, and other emerging biomarkers were recorded in this cohort. In this study, we show a detailed longitudinal description of the clinical and analytical parameters of this registry, with a special focus on the progress of renal function and cardiovascular events. The main objective is to analyze whether there are differential risk factors for renal function deterioration between sexes, as well as to analyze cardiovascular events and mortality in this population. In total, 650 patients with a median age of 69 (14) with different grades of chronic kidney disease­G1−G2 (eGFR > 90−60 mL/min/1.73 m2) 50.3%, G3 (eGFR; 59−30 mL/min/1.73 m2) 31.4%, G4 (eGFR; 29−15 mL/min/1.73 m2) 10.8%, and G5 (eGFR < 15 mL/min/1.73 m2) 7.5%­were followed up for 4.7 (0.65) years. Regardless of albuminuria, women lost 0.93 (0.40−1.46) fewer glomerular filtration units per year than men. A total of 17% of the participants experienced rapid deterioration of renal function, 75.2% of whom were men, with differential risk factors between sexes­severe macroalbuminuria > 300 mg/g for men OR [IQ] 2.40 [1.29:4.44] and concomitant peripheral vascular disease 3.32 [1.10:9.57] for women. Overall mortality of 23% was detected (38% of which was due to cardiovascular etiology). We showed that kidney function declined faster in men, with different risk factors compared to women. Patients with T2D and kidney involvement have very high mortality and an important cardiovascular burden. This cohort is proposed as a great tool for scientific collaboration for studies, whether they are focused on T2D, or whether they are interested in comparing differential markers between diabetic and non-diabetic populations.

Usefulness of Cardiac Computed Tomography in Coronary Risk Prediction: A Five-Year Follow-Up of the SPICA Study (Secure Prevention with Imaging of the Coronary Arteries).

Accurate identification of individuals at high coronary risk would reduce acute coronary syndrome incidence and morbi-mortality. We analyzed the effect on coronary risk prediction of adding coronary artery calcification (CAC) and Segment Involvement Score (SIS) to cardiovascular risk factors. This was a prospective cohort study of asymptomatic patients recruited between 2013-2017. All participants underwent a coronary computed tomography angiography to determine CAC and SIS. The cohort was followed-up for a composite endpoint of myocardial infarction, coronary angiography and/or revascularization (median = five years). Discrimination and reclassification of the REGICOR function with CAC/SIS were examined with the Sommer's D index and with the Net reclassification index (NRI). Nine of the 251 individuals included had an event. Of the included participants, 94 had a CAC = 0 and 85 a SIS = 0, none of them had an event. The addition of SIS or of SIS and CAC to the REGICOR risk function significantly increased the discrimination capacity from 0.74 to 0.89. Reclassification improved significantly when SIS or both scores were included. CAC and SIS were associated with five-year coronary event incidence, independently of cardiovascular risk factors. Discrimination and reclassification of the REGICOR risk function were significantly improved by both indexes, but SIS overrode the effect of CAC.

Real-World Use of Insulin Glargine U100 and U300 in Insulin-Naïve Patients with Type 2 Diabetes Mellitus: DosInGlar Study.

INTRODUCTION: In the EDITION clinical trial programme, patients with type 2 diabetes mellitus (T2DM) receiving insulin glargine (IGlar) U300 required 10-15% more insulin than those receiving IGlar U100. This study sought to determine whether this difference was apparent in real-world practice. METHODS: In this observational, retrospective cohort study, electronic medical records in the Big-Pac® database (Real Life Data) relating to adult insulin-naïve patients with T2DM who initiated IGlar U100 or U300 treatment in Spain in 2016-2017 and remained on treatment for 18 months were selected. IGlar U100- and U300-treated patients were matched 1:1 (propensity score matching). The primary analysis compared changes from baseline in mean daily IGlar dose (U and U/kg) at 6 (± 2), 12 (± 2) and 18 (± 2) months between cohorts (paired t tests). Changes in glycated haemoglobin (HbA1c) and weight were analysed descriptively. RESULTS: The IGlar U100 and U300 cohorts included 556 matched pairs (46.9% female) with the following mean (standard deviation) values at baseline, respectively: age 63.6 (12.8) versus 63.7 (11.9) years; years since diagnosis 9.5 (1.4) versus 9.5 (1.3); HbA1c 8.8 (1.3) versus 8.7 (1.5) %; weight 84.6 (16.9) versus 84.7 (17.1) kg. Mean IGlar dose at baseline was 0.19 U/kg/day (both cohorts). Patients receiving IGlar U300 showed a greater increase from baseline in IGlar dose at 6, 12 and 18 months [mean dose (U/kg/day) 5.1%, 10.3% and 12.8% greater, respectively, in IGlar U300-treated patients]. Mean HbA1c was 8.1% in both cohorts at 18 months. Mean (SD) weight at 18 months with IGlar U100 and IGlar300 was 86.8 (17.0) kg and 85.0 (17.1) kg, respectively. CONCLUSION: In real-world practice, insulin dose was significantly higher in IGlar U300-treated than U100-treated patients at 6, 12 and 18 months, with similar reductions in HbA1c. At equal IGlar price/unit in Spain, the increased dose requirements of IGlar U300 would result in higher costs.

Validation of a Diagnostic Support System for Diabetic Retinopathy Based on Clinical Parameters.

Purpose: To validate a clinical decision support system (CDSS) that estimates risk of diabetic retinopathy (DR) and to personalize screening protocols in type 2 diabetes mellitus (T2DM) patients. Methods: We utilized a CDSS based on a fuzzy random forest, integrated by fuzzy decision trees with the following variables: current age, sex, arterial hypertension, diabetes duration and treatment, HbA1c, glomerular filtration rate, microalbuminuria, and body mass index. Validation was made using the electronic health records of a sample of 101,802 T2DM patients. Diagnosis was made by retinal photographs, according to EURODIAB guidelines and the International Diabetic Retinopathy Classification. Results: The prevalence of DR was 19,759 patients (19.98%). Results yielded 16,593 (16.31%) true positives, 72,617 (71.33%) true negatives, 3165 (3.1%) false positives, and 9427 (9.26%) false negatives, with an accuracy of 0.876 (95% confidence interval [CI], 0.858-0.886), sensitivity of 84% (95% CI, 83.46-84.49), specificity of 88.5% (95% CI, 88.29-88.72), positive predictive value of 63.8% (95% CI, 63.18-64.35), negative predictive value of 95.8% (95% CI, 95.68-95.96), positive likelihood ratio of 7.30, and negative likelihood ratio of 0.18. The type 1 error was 0.115, and the type 2 error was 0.16. Conclusions: We confirmed a good prediction rate for DR from a representative sample of T2DM in our population. Furthermore, the CDSS was able to offer an individualized screening protocol for each patient according to the calculated risk confidence value. Translational Relevance: Results from this study will help to establish a novel strategy for personalizing screening for DR according to patient risk factors.

Overcoming psychological insulin resistance: A practical guide for healthcare professionals.

Despite the demonstrated benefits of using insulin, nearly a third of the patients with type 2 diabetes (T2D) are initially reluctant to initiate insulin therapy when it is first recommended by their healthcare provider (HCP). Several studies have documented the reasons for this phenomenon known as psychological insulin resistance (PIR) and also identified actionable strategies for HCPs to assist people with T2D to overcome their PIR. However, most strategies are based on the experiences of HCPs, rather than of patients. Based on findings from a study exploring real-world patient experience around HCP actions for mitigating PIR, we suggest that HCPs use collaborative strategies throughout the course of T2D treatment to 1) explore reasons for PIR, 2) help patients overcome PIR, and 3) follow-up regarding experience with insulin.

Ambulatory Blood Pressure Levels in the Prediction of Progression of Cerebral Small Vessel Disease.

OBJECTIVES: We aimed to study the value of ambulatory blood pressure monitoring (ABPM) in predicting the global progression of cerebral small vessel disease (cSVD). DESIGN: Longitudinal cohort study. SETTING: Data from the population-based Investigating Silent Strokes in Hypertensives study. PARTICIPANTS: Individuals with hypertension who were 50 to 70 years of age and stroke free at baseline. In baseline and follow-up visits, patients underwent magnetic resonance imaging and ABPM. MEASUREMENTS: Ambulatory systolic blood pressure (SBP) and diastolic blood pressure (DBP) levels were studied as continuous variables and dichotomized according to good or poor control on the basis of 125/75 (24 hours), 130/80 (day), and 110/65 (night) mm Hg cutoff values. Whole cSVD progression was qualitatively scored with 1 point when an incident lesion (incident lacunar infarcts, deep cerebral microbleeds, white matter hyperintensities, and basal ganglia enlarged perivascular spaces) was detected. The score ranged from 0 to 4. RESULTS: We followed up 233 participants with a median age of 65 years within 4 years. A total of 61 (26.2%) and 23 (9.9%) subjects showed cSVD progression in one and two or more markers, respectively. Baseline ambulatory SBP and DBP and nighttime pulse pressure (PP) values were positively correlated with the number of incident cSVD lesions. Interestingly, patients without incident lesions showed greater differences between office and ambulatory BP, thus suggesting an increased white coat effect. Poor DBP control, nighttime PP, and DBP white coat effect were independently associated with cSVD progression. The inclusion of these metrics in a clinical model resulted in a significant increase in the prediction of incident lesions (integrated discrimination improvement = 9.09%; P value <.001). CONCLUSION: ABPM may help assess cSVD risk of progression, especially by the identification of poor BP control, masked hypertension, and increased nighttime PP. J Am Geriatr Soc 68:2232-2239, 2020.

Identifying solutions to psychological insulin resistance: An international study.

AIMS: To identify actions of healthcare professionals (HCPs) that facilitate the transition to insulin therapy (IT) in type 2 diabetes (T2D) adults. METHODS: Included were T2Ds in seven countries (n = 594) who reported initial IT reluctance but eventually began IT. An online survey included 38 possible HCP actions: T2Ds indicated which may have occurred and their helpfulness. Also reported were delays in IT start after initial recommendation and any period of IT discontinuation. RESULTS: Exploratory factor analysis of HCP actions yielded five factors: "Explained Insulin Benefits" (EIB), "Dispelled Insulin Myths" (DIM), "Demonstrated the Injection Process" (DIP), "Collaborative Style" (CS) and "Authoritarian Style" (AS). Highest levels of helpfulness occurred for DIP, EIB and CS; lowest for AS. Participants who rated DIP as helpful were less likely to delay IT than those who rated DIP as less helpful (OR = 0.75, p = 0.01); participants who rated CS and EIB as helpful were less likely to interrupt IT than those who rated these as less helpful (OR = 0.55, p < 0.01; OR = 0.51, p = 0.01, respectively). CONCLUSIONS: Three key HCP actions to facilitate IT initiation were identified as helpful and were associated with more successful initiation and persistence. These findings may aid the development of interventions to address reluctance to initiating IT.

Cognitive Impact of Cerebral Small Vessel Disease Changes in Patients With Hypertension.

Hypertension is one of the principal risk factors for cerebral small vessel disease progression and cognitive impairment. We aimed to investigate how changes in cerebral small vessel disease lesions relate to cognitive decline and incident mild cognitive impairment in hypertensive patients. Data were obtained from the ISSYS cohort (Investigating Silent Strokes in Hypertensives: a Magnetic Resonance Imaging Study)-a longitudinal population-based study on hypertensive patients aged 50 to 70 years without dementia and stroke at baseline. Patients underwent a brain magnetic resonance imaging, a cognitive screening test, and cognitive diagnosis (normal aging or mild cognitive impairment) at baseline and follow-up. We evaluated incident lacunar infarcts and cerebral microbleeds. Changes in the periventricular and deep white matter hyperintensities (WMH) were qualitatively defined as none, minor, or marked. We followed up 345 patients (median age, 65 [61-68]; 55.4% men) for 3.95 (3.83-4.34) years. Incident mild cognitive impairment was diagnosed in 9.1% of the sample. Considering the progression of cerebral small vessel disease, the prevalence of incident infarcts was 6.1% and that of incident cerebral microbleeds was 5.5%; progression of periventricular WMH was 22% and that of deep WMH was 48%. Patients with marked progression of periventricular WMH showed a significant decrease in global cognition compared with patients without progression (adjusted mean [SE], -0.519 [0.176] versus 0.057 [0.044], respectively; P value=0.004) and a higher risk of incident mild cognitive impairment (OR, 6.184; 95% CI, 1.506-25.370; P value=0.011). Therefore, our results indicate that hypertensive patients with progression of periventricular WMH have higher odds of cognitive impairment, even in the early stages of cognitive decline.

The prognostic value of blood pressure control delay in newly diagnosed hypertensive patients.

OBJECTIVE: Various studies have suggested that a delay in the time between diagnosing hypertension and its correct control (D-C, diagnostic-control time) is linked to a worse prognosis. The aim of this study was to examine the relationship between D-C time and all-cause mortality, or the incidence of cardiovascular events, in patients more than 60 years newly diagnosed with hypertension. METHODS: This is a longitudinal, retrospective, population study employing data gathered from the electronic medical records of patients recently diagnosed with hypertension in 45 primary healthcare centres located in Barcelona (Catalonia). A multivariable logistic regression and Cox regression models were constructed. Goodness-of-fit was assessed through the Hosmer & Lemeshow test. RESULTS: A total of 18 721 newly diagnosed hypertensive patients were included between 2007 and 2012. The follow-up lasted until October 2015, or the appearance of a cardiovascular event or death because of any cause. The median D-C time was 49 days and its distribution by tertiles was the following: 29 days or less, 30-124 days, and at least 125 days. Higher hypertensive status, obesity, diabetes mellitus, and male sex were independently associated with longer D-C time (≥125 days). At 5.4 years follow-up, patients with longer D-C times presented statistically significant greater incidence of all-cause mortality. CONCLUSION: A delay in blood pressure control is significantly associated with an increase in the rate of all-cause mortality.

Arterial Stiffness Is Associated With Basal Ganglia Enlarged Perivascular Spaces and Cerebral Small Vessel Disease Load.

BACKGROUND AND PURPOSE: We assessed whether the load of cerebral small vessel disease (cSVD) and its individual markers, including lacunes, white matter hyperintensities, microbleeds, and enlarged perivascular spaces (EPVS), are associated with arterial stiffness. METHODS: We evaluated cSVD markers in a cohort of 782 hypertensive individuals without history of stroke or dementia. The load of the disease was calculated using an ordinal scale ranging from 0 to 4 (1 point was given for each of the 4 markers examined). The arterial stiffness was tested by measuring the carotid-femoral pulse wave velocity with an oscillometric automatic device. RESULTS: The mean age of the participants (49.6% women) was 62.7±5.4 years, and the mean systolic/diastolic blood pressure was 142.9/77.3 mm Hg (55.5% of the participants had poor blood pressure control). We found 7.2% cases with lacunes, 6.4% with microbleeds, 6.7% with extensive white matter hyperintensities, 24.5% with extensive basal ganglia EPVS, and 40.1% with extensive EPVS in the centrum semiovale. Regarding the cSVD load, 19.7% of the participants scored 1, 6.5% scored 2, and 1.4% scored ≥3. The median carotid-femoral pulse wave velocity was 10.5 m/s (interquartile range, 9.2-11.9) and was associated with lacunes (odds ratio per carotid-femoral pulse wave velocity SD increase, 1.51; 95% confidence interval, 1.13-2.03), extensive basal ganglia EPVS (odds ratio, 1.39; 95% confidence interval, 1.16-1.67), and cSVD load (common odds ratio, 1.42; 95% confidence interval, 1.19-1.68). CONCLUSIONS: We found that, in a cohort of hypertensive individuals, the arterial stiffness is associated with the total load of the cSVD, especially with lacunes and basal ganglia EPVS.

Asociación de obesidad general y abdominal con hipertensión, dislipemia y presencia de prediabetes en el estudio PREDAPS / Association of general and abdominal obesity with hypertension, dyslipidemia and prediabetes in the PREDAPS study

Introducción y objetivos: Algunas medidas antropométricas muestran mayor capacidad que otras para discriminar la presencia de factores de riesgo cardiovascular. Este trabajo estima la magnitud de la asociación de diversos indicadores antropométricos de obesidad con hipertensión, dislipemia y prediabetes (glucemia basal o glucohemoglobina alteradas). Métodos: Análisis transversal de la información recogida en 2.022 sujetos del estudio PREDAPS (etapa basal). Se definió obesidad general como índice de masa corporal ≥ 30 kg/m2 y obesidad abdominal con 2 criterios: a) perímetro de cintura (PC) ≥ 102 cm en varones/PC ≥ 88 cm en mujeres, y b) índice cintura/estatura (ICE) ≥ 0,55. La magnitud de la asociación se estimó mediante regresión logística. Resultados: La hipertensión arterial mostró la asociación más alta con la obesidad general en mujeres (OR = 3,01; IC95%, 2,24-4,04) y con la obesidad abdominal según el criterio del ICE en varones (OR = 3,65; IC95%, 2,66-5,01). La hipertrigliceridemia y los valores bajos de colesterol unido a lipoproteínas de alta densidad mostraron la asociación más alta con obesidad abdominal según el criterio del ICE en mujeres (OR = 2,49; IC95%, 1,68-3,67 y OR = 2,70; IC95%, 1,89-3,86) y la obesidad general en varones (OR = 2,06; IC95%, 1,56-2,73 y OR = 1,68; IC95%, 1,21-2,33). La prediabetes mostró la asociación más alta con obesidad abdominal según el criterio del ICE en mujeres (OR = 2,48; IC95%, 1,85-3,33) y con obesidad abdominal según el criterio del PC en varones (OR = 2,33; IC95%, 1,75-3,08). Conclusiones: Los indicadores de obesidad abdominal mostraron la mayor asociación con la presencia de prediabetes. La relación de los indicadores antropométricos con hipertensión y con dislipemia mostró resultados heterogéneos (AU)

Introduction and objectives: Some anthropometric measurements show a greater capacity than others to identify the presence of cardiovascular risk factors. This study estimated the magnitude of the association of different anthropometric indicators of obesity with hypertension, dyslipidemia, and prediabetes (altered fasting plasma glucose and/or glycosylated hemoglobin). Methods: Cross-sectional analysis of information collected from 2022 participants in the PREDAPS study (baseline phase). General obesity was defined as body mass index ≥ 30 kg/m2 and abdominal obesity was defined with 2 criteria: a) waist circumference (WC) ≥ 102 cm in men/WC ≥ 88 cm in women, and b) waist-height ratio (WHtR) ≥ 0.55. The magnitude of the association was estimated by logistic regression. Results: Hypertension showed the strongest association with general obesity in women (OR, 3.01; 95%CI, 2.24-4.04) and with abdominal obesity based on the WHtR criterion in men (OR, 3.65; 95%CI, 2.66-5.01). Hypertriglyceridemia and low levels of high-density lipoprotein cholesterol showed the strongest association with abdominal obesity based on the WHtR criterion in women (OR, 2.49; 95%CI, 1.68-3.67 and OR, 2.70; 95%CI, 1.89-3.86) and with general obesity in men (OR, 2.06; 95%CI, 1.56-2.73 and OR, 1.68; 95%CI, 1.21-2.33). Prediabetes showed the strongest association with abdominal obesity based on the WHtR criterion in women (OR, 2.48; 95%CI, 1.85-3.33) and with abdominal obesity based on the WC criterion in men (OR, 2.33; 95%CI, 1.75-3.08). Conclusions: Abdominal obesity indicators showed the strongest association with the presence of prediabetes. The association of anthropometric indicators with hypertension and dyslipidemia showed heterogeneous results (AU)

Dementia Rating Scale-2 normative data for middle-and older-aged Castilian speaking Spaniards.

OBJECTIVES: The Dementia Rating Scale-2 (DRS-2) is frequently used as a dementia screening tool in clinical and research settings in Spain. The present study describes DRS-2 Total and subscale scores in community-dwelling Spaniards, aged 50-71, and provides normative data for its use in Castilian Spanish-speaking individuals. METHODS: The sample consisted of 798 individuals who participated in an observational study on essential hypertension. Mean age was 62.8 years (SD = 5.4), mean education was 8.6 years (SD = 3.4) with 47.9% females. Almost all of them were receiving blood pressure-lowering drugs (93%) and most of them had fairly well-managed blood pressure control (M systolic/diastolic blood pressure = 142.3/77.0 ± 16.0/9.2 mm Hg). We applied a previously described method of data normalization from the Mayo's Older Americans Normative Studies to obtain the Castilian Spanish DRS-2 norms. RESULTS: Worse performance on Total and subscale scores was associated with older age (p < .05) and fewer years of education (p < .001). Women obtained lower raw Total scores than men (131.68 ± 7.2 vs. 133.10 ± 6.90, p < .005), but had fewer years of education (7.96 ± 3.33 vs. 9.17 ± 3.45, p < .001). This gender difference disappeared after correcting for age and years of education. Total and subscale scores are presented adjusted by age, and normative data are shown for Total scores adjusted by age and years of education. CONCLUSIONS: These norms are useful for studying cognitive status and cognitive decline in research and clinical settings in Castilian Spanish-speaking populations.

Microalbuminuria and the Combination of MRI Markers of Cerebral Small Vessel Disease.

BACKGROUND: Kidney function has been related to the presence of individual markers of cerebral small vessel disease (CSVD), as lacunes, white matter hyperintensities (WMH) or microbleeds. We aimed at studying the relationship of kidney dysfunction with the combination of several markers of CSVD. METHODS: Subjects are those included in the ISSYS cohort (Investigating Silent Strokes in hypertensives: a magnetic resonance imaging study). A scale ranging from 0 to 4 points was applied based on the presence (one point each) of lacunes, deep microbleeds, moderate to extensive basal ganglia enlarged perivascular spaces (EPVS), and periventricular or deep WMH. We determined the creatinine-based glomerular filtration rate and the urinary albumin-to-creatinine ratio (UACR) as markers of kidney function and studied their association with the scale of CSVD in univariate and ordinal logistic regression analyses. RESULTS: Among the 975 patients included, 28.2% presented one or more CSVD markers, being the most prevalent marker (either alone or in combination) basal ganglia EPVS. The UACR was elevated at increasing the scores of the CSVD scale and remained as independent predictor of the combination of markers (common OR per natural log unit increase in UACR: 1.23, 1.07-1.41) after controlling per age, gender, cardiovascular risk, antihypertensive treatment and hypertension duration. In contrast, no associations were found between the CSVD scores and the creatinine-based estimated glomerular filtration rate. CONCLUSIONS: A significant proportion of stroke-free hypertensives present at least one imaging marker of CSVD. UACR but not creatinine-based glomerular filtration rate is associated with the combination of markers of CSVD.

Incidence of peripheral arterial disease in the ARTPER population cohort after 5 years of follow-up.

BACKGROUND: To know the epidemiology (prevalence, incidence, progression and morbidity and mortality associated) of peripheral artery disease in general population and the factors associated with this progression is essential to know the evolution of atherosclerosis and develop preventive strategies. The aim of the study was to determine the incidence of PAD after 5 years of follow-up population-based cohort ARTPER, and the evolution of Ankle brachial Index (ABI) in this period. METHODS: Peripheral artery disease incidence analysis after 5 years of follow-up of 3786 subjects > 50 years old. Peripheral artery disease incident when the second cross section Ankle brachial Index was <0.9 in any of the lower limbs, with normal baseline (0.9 to 1.4). RESULTS: Between 2012 and 2013 2762 individuals (77% participation) were re-examined . Finally analyzed 2256 subjects (after excluding pathological Ankle brachial Index) followed for 4.9 years (range 3.8 to 5.8 years), totalling 11,106 person-years. Peripheral artery disease 95 new cases were detected, representing an incidence of 4.3% at 5 years and 8.6 per 1000 person-years (95% CI 6.9 to 10.5) being higher in men (10.2, 95% CI 7.4 to 13.5) than in women (7.5, 95% CI 5.5 to 9.9). Linear correlation between the baseline Ankle brachial Index and the second cross section was low (r = 0.23). CONCLUSIONS: The incidence of peripheral artery disease in ARTPER cohort was 8.6 cases per 1000 person-years, being higher in men, especially <65 years. The correlation between two measures Ankle brachial Index after 5 years of follow-up was low. One might consider whether Ankle brachial Index repeated measures could improve the correlation.

High daytime and nighttime ambulatory pulse pressure predict poor cognitive function and mild cognitive impairment in hypertensive individuals.

High blood pressure accelerates normal aging stiffness process. Arterial stiffness (AS) has been previously associated with impaired cognitive function and dementia. Our aims are to study how cognitive function and status (mild cognitive impairment, MCI and normal cognitive aging, NCA) relate to AS in a community-based population of hypertensive participants assessed with office and 24-hour ambulatory blood pressure measurements. Six hundred ninety-nine participants were studied, 71 had MCI and the rest had NCA. Office pulse pressure (PP), carotid-femoral pulse wave velocity, and 24-hour ambulatory PP monitoring were collected. Also, participants underwent a brain magnetic resonance to study cerebral small-vessel disease (cSVD) lesions. Multivariate analysis-related cognitive function and cognitive status to AS measurements after adjusting for demographic, vascular risk factors, and cSVD. Carotid-femoral pulse wave velocity and PP at different periods were inversely correlated with several cognitive domains, but only awake PP measurements were associated with attention after correcting for confounders (beta = -0.22, 95% confidence interval (CI) -0.41, -0.03). All ambulatory PP measurements were related to MCI, which was independently associated with nocturnal PP (odds ratio (OR) = 2.552, 95% CI 1.137, 5.728) and also related to the presence of deep white matter hyperintensities (OR = 1.903, 1.096, 3.306). Therefore, higher day and night ambulatory PP measurements are associated with poor cognitive outcomes.

Impact of the sustained control of cardiovascular risk factors on first episode heart failure: The relevant role of primary care.

BACKGROUND: The role of cardiovascular risk factor control in the development of heart failure (HF) has not yet been clearly established. OBJECTIVE: To determine the effect of cardiovascular risk factor control on the occurrence of a first episode of hospital admission for HF. METHODS: A case-control study using propensity score-matching was carried out to analyse the occurrence of first hospital admission for HF taking into account the degree of cardiovascular risk factor control over the previous 24 months. All patients admitted to the cardiology unit of the Hospital del Mar between 2008 and 2011 because of a first episode of HF were considered cases. Controls were selected from the population in the hospital catchment area who were using primary care services. Cardiovascular risk factor measurements in the primary healthcare electronic medical records prior to the first HF episode were analysed. RESULTS: After the matching process, 645 participants were analysed (129 HF cases and 516 controls). Patients suffering a first HF episode had modest increments in body mass index and blood pressure levels during the previous two years. Adjusted odds ratio for experiencing a first HF hospital admission episode according to systolic blood pressure levels and body mass index was (OR: 1.031, 95% CI: 1.001-1.04), and (OR: 1.09, 95% CI: 1.03-1.15), respectively. CONCLUSION: Increased levels of body mass index and systolic blood pressure during the previous 24 months may determine a higher risk of having a first HF hospital admission episode.

Short-Term Blood Pressure Variability Relates to the Presence of Subclinical Brain Small Vessel Disease in Primary Hypertension.

Blood pressure (BP) variability is associated with stroke risk, but less is known about subclinical cerebral small vessel disease (CSVD). We aimed to determine whether CSVD relates to short-term BP variability independently of BP levels and also, whether they improve CSVD discrimination beyond clinical variables and office BP levels. This was a cohort study on asymptomatic hypertensives who underwent brain magnetic resonance imaging and 24-hour ambulatory BP monitoring. Office and average 24-hour, daytime and nighttime BP levels, and several metrics of BP variability (SD, weighted SD, coefficient of variation, and average real variability [ARV]) were calculated. Definition of CSVD was based on the presence of lacunar infarcts and white matter hyperintensity grades. Multivariate analysis and integrated discrimination improvement were performed to assess whether BP variability and levels were independently associated with CSVD and improved its discrimination. Four hundred eighty-seven individuals participated (median age, 64; 47% women). CSVD was identified in 18.9%, related to age, male sex, diabetes mellitus, use of treatment, ambulatory BP monitoring-defined BP levels, and ARV of systolic BP at any period. The highest prevalence (33.7%) was found in subjects with both 24-hour BP levels and ARV elevated. BP levels at any period and ARV (24 hours and nocturnal) emerged as independent predictors of CSVD, and discrimination was incrementally improved although not to a clinically significant extent (integrated discrimination improvement, 5.31%, 5.17% to 5.4%). Ambulatory BP monitoring-defined BP levels and ARV of systolic BP relate to subclinical CSVD in hypertensive individuals.
