RESUMO
BACKGROUND: Lead (Pb), cadmium (Cd) and mercury (Hg) are toxic trace elements that represent a public health problem as risk factors for cardiovascular disease and hypertension (HT) and could also contribute to the development of resistant hypertension (rHT) AIMS: To compare the blood concentrations of Pb, Cd and Hg in subjects with resistant and non-resistant HT and to define whether there is a relationship between its levels and rHT. METHODS: Cross-sectional study. Subjects aged ≥ 21 to ≤ 80 years with a body mass index < 40â¯kg/m2 were recruited on a discretionary basis from October 2001 to October 2004 in a hypertension unit of a tertiary hospital amongst those sent to the hypertension unit by their family physician. Resistant hypertension was defined according to the American Heart Association (AHA) criteria. Whole blood concentrations of Cd, Pb and Hg were measured by electrothermal atomic absorption spectrometry. RESULTS: 46 out of 73 included subjects (63%) suffered from rHT. Blood Pb median: HT 3.9 (IQR 2.7-5.2) vs. rHT 3.6 (IQR 2.8-6.0) µg/dL (p=0.941). Blood Cd median: HT 0.07 (IQR 0.07-0.80) vs. rHT 0.30 (IQR 0.07-0.65) µg/L (p=0.681). Blood Hg median: HT 7.9 (IQR 5.8-12.9) vs. rHT 7.3 (IQR 4.6-13.3) µg/L (p=0.611). Considering the 75th percentile of each element (Pb: 5.55⯵g/dL, Cd: 0.75⯵g/L, Hg: 13.15⯵g/L), a multiple logistic regression analysis (adjusted for age, BMI, diabetes mellitus, clearance of creatinine and only for Cd the smoking habit) showed an OR = 3.44 (0.84-14.10, p=0.086) for Pb, OR = 1.80 (0.39-8.24, p=0.451), for Cd and OR = 2.31 (0.59-9.14, p=0.232) for Hg. Moreover, the stratified analyses showed that men with Pb ≥5.55⯵g/dL have a 14 times higher risk of suffering from rHT (p=0.026). Interestingly, a 9-fold increased risk was found for non-obese subjects with elevated Pb levels, above 5.55⯵g/dL (p=0.029). Also in men, the probability of suffering from rHT was more than 7 times higher if Cd levels were ≥ 0.75⯵g/L (p=0.076). Most smokers had higher Cd levels, with a high risk of suffering from rHT (ORa 12.6 (0.8-200.2), p=0.072). CONCLUSION: A higher blood Pb levels, defined by the 75th percentile (Pb ≥ 5.55⯵g/dL), is associated with a greater risk of suffering from rHT and to a lesser extent in the case of Cd and Hg.

BACKGROUND: Laparoscopic adrenalectomy (LA) is the gold standard treatment for unilateral primary aldosteronism. However, satisfactory results have also been published with radiofrequency ablation (RFA). The aim of this study was to compare LA and RFA for the treatment of primary aldosteronism. METHODS: A retrospective cohort study of the patients who underwent LA or RFA in a single center was performed. Morbidity and long-term effectiveness (cure rate and blood pressure control) were analyzed. A multivariate analysis with a propensity score was also performed. RESULTS: Thirty-four patients were included in the study, 24 in the LA group and 10 in the RFA group. Hypertension had been diagnosed a median of 12 years before the intervention. Hypertension was properly controlled before the intervention in 55.9% of the patients. Hypertensive crisis was more common during RFA (4.2% vs. 70.0%, p < 0.001), although no patient suffered any complication because of these crises. LA was longer (174.6 vs. 105.5 min, p = 0.001) and had a longer length of stay (median 2 vs 1 days, p < 0.001). No severe complications were observed in any of the patients. After a median follow-up of 46.2 months, more patients had hypertension cured and blood pressure controlled in the LA group (29.2% vs. 0%, p = 0.078 and 95.5% vs. 50.0%, p = 0.006, respectively). Also, patients in the LA group were taking less antihypertensive drugs (1.8 vs. 3.0, p = 0.054) or mineralocorticoid receptor antagonists (41.7% vs. 90.0%, p = 0.020). Multivariate analysis adjusted by propensity score showed that LA had an OR = 11.3 (p = 0.138) for hypertension cure and an OR = 55.1 (p = 0.040) for blood pressure control. CONCLUSIONS: Although RFA was a less invasive procedure than LA, hypertension was cured and blood pressure was properly controlled in more patients from the LA group. Patients who underwent LA were taking less antihypertensive drugs than patients who had undergone RFA.

Objective: the treatment for gestational diabetes is based on diet, and this may modify maternal weight gain. The limited maternal weight gain is related to newborns with small weight for their gestational age (SGA), and many studies have found an increase of SGA in women with gestational diabetes (GD), but the reason for this is not clear. The objective of this study is to evaluate the effects of gestational diabetes treatment on maternal weight gain and neonatal weight. Methods: a retrospective cohort study of 1,765 patients with GD, according to the National Diabetes Data Group (NDDG) criteria. We assessed: pre-pregnancy BMI, total maternal weight gain (MWG), weight gain during the third trimester, gestational week of starting the treatment, and treatment modality (diet or diet plus insulin). Birth weight was adjusted by gestational age and gender: SGA (= 10th) and large for gestational age (LGA) ( > 90th). Results: the percentage of newborns with weight percentile = 10 was 14.8%. The diet and the time of initiation of the treatment were related to maternal weight gain (MWG) in the third trimester. For every 1 kcal/kg of variation in the diet (increase or decrease), a MWG variation of 0.03 (0.001-0.06) kg occurred (p < 0.01). For each week before the beginning of treatment, the mother did not gain 0.13 ± [(-0.15) - (-0.11)] kg in the third trimester (p < 0.01). The SGA was related to the lowest MWG in total gestation: 7.0 (IQR 3.0-10.4) kg vs. 8.4 (IQR 5.0-11.6) kg (p < 0.01), and in the third trimester: 0.3 (IQR -0.9-1.5) kg vs. 0.9 (IQR -0.3-2.2) kg (p < 0.01). Conclusion: the dietary treatment for gestational diabetes leads to a lower maternal weight gain and induces an impact on neonatal weight
Objetivo: el tratamiento para la diabetes gestacional se basa en la dieta y esto puede modificar el aumento de peso materno. Un aumento de peso materno limitado está relacionado con recién nacidos con bajo peso para su edad gestacional (SGA). Muchos estudios han encontrado un aumento de niños con bajo peso en mujeres con diabetes gestacional, pero la razón de esto no está clara. El objetivo de este estudio es evaluar los efectos del tratamiento de la diabetes gestacional sobre el aumento de peso materno y el peso neonatal. Métodos: estudio de cohortes retrospectivo en 1765 pacientes con diabetes gestacional, según los criterios de los National Diabetes Data Groups (NDDG). Evaluamos: IMC antes del embarazo, aumento de peso materno total (MWG), aumento de peso durante el tercer trimestre, semana gestacional de inicio del tratamiento y modalidad de tratamiento (dieta o dieta más insulina). El peso al nacer se ajustó por edad gestacional y género: SGA (percentil de = 10) y grande para la edad gestacional (LGA) (percentil de > 90). Resultados: el porcentaje de recién nacidos con peso percentil de = 10 fue del 14,8%. La dieta y el momento de inicio del tratamiento se relacionaron con el aumento de peso materno en el tercer trimestre. Por cada 1 kcal/kg de variación en la dieta (aumento o disminución) se produjo una variación de aumento del peso materno de 0,03 (0,001-0.06) kg (p < 0,01). Por cada semana antes de inicio del tratamiento, la madre dejó de ganar 0,13 ± [(- 0,15) - (- 0,11)] kg en el tercer trimestre (p < 0,01). El SGA se relacionó con un aumento de peso materno más bajo en el total de la gestación: 7,0 (IQR 3,0-10,4) kg vs. 8,4 (IQR 5,0-11,6) kg (p < 0,01), y en el tercer trimestre: 0,3 (IQR -0,9-1,5) kg vs. 0,9 (IQR -0,3-2,2) kg (p < 0,01). Conclusión: el tratamiento dietético para la diabetes gestacional puede conducir a un menor aumento de peso materno y a su vez inducir un impacto en el peso neonatal

Introduction: Digital interventions, such as smartphone applications (apps), are becoming an increasingly common way to support medication adherence and self-management in chronic illness.Aim: To evaluate the effectiveness of the intervention in pharmacological therapeutic adherence in mild to moderate arterial hypertension (AHT), through an app installed on a mobile phone, as well as the degree of control reached by the patient with this tool.Methods: Prospective, randomized controlled trial, full study and multicenter study. Four primary care centers participated. One hundred and fifty-four hypertensive patients under antihypertensive treatment were included. Two groups were established: a control group (CG) with usual intervention (n = 77) and an intervention group (n = 77) (IG), targeting hypertensive people who owned and regularly used a mobile smartphone, specifically using the app called AlerHTA to promote health education and reminder of appointments. There were three visits: initial, 6 and 12 months. Drug adherence was measured by electronic monitors (MEMSs). The primary outcomes were average daily percentage adherence between 80 and 100%, and AHT control.Results: A total of 148 patients finished the study. Mean age was 57.5 ± 9.9. Global adherence was 77.02% (CI = 70.25-83.79) and daily adherence was 74.32% (CI = 67.29-81.35%). Daily adherence was 93.15% and 86.3% in IG, and 70.66% and 62.66% in CG after 6 and 12 months respectively (p < .05). The percentage of uncontrolled patients was 28.3% (CI = 21.05-35.55%). The control of high blood pressure at 12 months was 17.8% and 38.6% for IG and CG respectively (p < .05). The number of patients needed to treat to avoid non-adherence (NNT) was 4.23 patients.Conclusions: The intervention with an app installed on the mobile phones of hypertensive patients favors pharmacological therapeutic adherence and improves the percentage of hypertensive patient control.Trial registration: Spanish Agency of Medicine: EPA-SP UN-HTA-2015-01.

AIM: The aim of this study is to find whether the worsening of health perception was related to the menopausal (MNP) state or to its negative consequences on cardiometabolic risk factors (CMRF) and the presence of depression/anxiety. METHODS: In this study, 2,562 women, 1,357 (53%) MNP and 1,205 (47%) non-MNP, were analyzed. Blood pressure, heart rate, body mass index, waist circumference, and depression/anxiety screening using the Hospital Depression/Anxiety Scale (HADS) were measured. We collected a blood sample in fasting state for glycemia, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and triglycerides. Logistic regression models were fitted with a backward method from the potentially confusing variables of the menopause study groups. RESULTS: Age 49.4 (±15.9) years; 10.1% belonged to semi-rural population; 87.5% had children. Regarding the educational level, 22.1% had <5 years of education, 31.3% had between 6 and 7 years, 33.4% had between 8 and 12 years, and 13.2% had >12 years of education. The prevalence of CMRF was significantly higher in MNP women, except for smoking. We did not find any differences in the prevalence of depression or anxiety between MNP and non-MNP women. Health was perceived as worse among MNP women (P<0.05) and patients over 45 years of age than patients younger than 45 years. We found a relationship between the negative health perception with metabolic syndrome, depression, and anxiety, having children, smoking, residing in rural area, and low educational level; nevertheless, it is not correlative with MNP status. CONCLUSION: Perceived health should be viewed as a multifaceted condition related to social circumstances, and various symptoms in women, including menopause symptoms, but not with MNP state itself.
RESUMO
INTRODUCCIÓN: Estudiar la opinión del médico de atención primaria (MAP) de la información de los pacientes remitida desde el médico especialista en hipertensión arterial (MEHTA). DISEÑO: Estudio observacional descriptivo. Emplazamiento: Realizado a nivel nacional. PARTICIPANTES: Médicos de atención primaria que reciben hipertensos estudiados por MEHTA. MÉTODOS: Se utilizó el consenso de derivación de la SEH-LELHA, y una encuesta en la que se recogían en la visita basal las características demográficas, antropométricas, presión y causa de derivación; en la posderivación se añaden preguntas sobre: tiempo utilizado en estudiar al paciente, modificaciones del diagnóstico y fármacos. Además se preguntó sobre el tiempo en recibir respuesta y se pidió la valoración del informe que le remite el MEHTA. RESULTADOS: Participaron 578 investigadores de AP que incluyeron 1.715 pacientes válidos. Edad 60,7 ± 13,3 años, varones 62,7%. En prederivación los pacientes tomaban 2,3 ± 1,2 fármacos antihipertensivos, y 2,5 ± 1,2 en posderivación; la presión arterial pasó de 166 ± 21.6 /97,7±12,6 mmHg a 143 ± 14,4 /85,5 ± 10,5mmHg. Los pacientes controlados (PA < 140 y < 90 mmHg) pasaron del 5,8 al 32,2%. El tiempo transcurrido entre la visita al hospital y la recepción del informe fue de 72 ± 64días. Se realizó ampliación del estudio por parte del MEHTA en 1.250 casos (72,9%). El MAP médico de familia recibió informe reglado en el 80,3% de los casos. Globalmente, el 63% de los MAP están totalmente de acuerdo con la actuación del especialista, el 29% parcialmente de acuerdo y el 2% nada de acuerdo. La derivación se ha valorado mediante opinión subjetiva del MAP como efectiva o muy efectiva en el 86% de los pacientes y nada efectiva en el 9%. CONCLUSIONES: La comunicación entre niveles es clave en el cuidado de algunos pacientes hipertensos, como corresponde a una entidad crónica
INTRODUCTION: To know the opinion/evaluation of the primary care physicians (PCPH) of the received information about patients that were attended in specialized care (SC). DESIGN: Cross-sectional study. LOCATION: Performed nationwide in primary care centers. PARTICIPANTS: Researchers from the primary care network. METHODS: We used the SEH-LELHA derivation criteria guidelines, plus an ad hoc survey that included demographic and anthropometric data, blood pressure levels, and the main reason for derivation to SC at the baseline and final (post-derivation) visit. In addition, time deployed for the study of every patient, changes in diagnosis and treatment, type of follow-up, issues throughout the derivation process and assessment of the medical referred to the PCPH were evaluated. RESULTS: With participation of 578 researchers from primary, the study included 1715 patients aged 60.7 ± 13.3 years, 62.7% male. Patients were taking 2.3 ± 1.2 (range 0-10) antihypertensive drugs pre-referral and 2.5 ± 1.2 (0-9) after derivation. Blood pressure levels changed from 166 ± 21.6 /97.7 ± 12.6mmHg to 143 ± 14.4 /85.5 ± 10.5 mmHg. The number of controlled patients (BP < 140 and < 90 mmHg) increased from 5.8% to 32.2%. Time between pre- and post-derivation visit was 72 ± 64days (median 57 days, IQ26-99). The PCPH received a medical report in 80.3% of cases, 76.9% with an explanation of the results of the complementary tests, 75.8% with additional information or a reasoning of treatment and in 71% of cases information about the patient future management. 63% of PCPH were fully agreed with the management of the specialist, 29% agree and 2% strongly disagree. The derivation was evaluated as effective or very effective in 86% of patients and no effective in 9%. CONCLUSIONS: Communication between AE and SC in HTA is valued satisfactorily by MAP. However there is still room for improvement in the process

OBJECTIVE: To validate electronic prescriptions (e-prescriptions) as a method for measuring treatment adherence in patients with hypertension. METHODS: This prospective study initially included 120 patients treated for hypertension in primary care centers. Adherence was measured using the gold standard, the medication event monitoring system (MEMS), versus the index test, the e-prescription program, at baseline and at 6, 12, 18 and 24 months. We calculated the adherence rate using the MEMS and the medication possession ratio (MPR) for the e-prescriptions. We considered patients adherent if they had an adherence rate of 80% to 100%. To validate the e-prescription, we obtained measures of diagnostic accuracy, the Kappa concordance index, and the area under the ROC curve (AUC). RESULTS: We included 102 patients. Overall adherence was 77.4% by MEMS (95%CI: 66.8-88) and 80.4% (95%CI: 70.3-90.5) by MPR. At 24 months, sensitivity was 87% and specificity, 93.7%. The AUC was 0.903 (95%CI: 0.817-0.989). CONCLUSION: Measures of treatment adherence were not significantly different between e-prescription and gold standard at most visits, and the e-prescription showed good discriminatory diagnostic capacity. PRACTICE IMPLICATIONS: If patients are included in an e-prescription program for at least 2 years, e-prescription is an inexpensive method to measure adherence in hypertension.

Objective To assess the efficacy of a mixed intervention, educational, and reminder calendar of the intake, as a strategy to improve therapeutic adherence with dabigatran in patients with non-valvular atrial fibrillation (NVAF). Methods This was a prospective, longitudinal, multi-center study, carried out in 110 specialized healthcare centers in Spain. Seven hundred and twenty-six patients treated with dabigatran prescribed for stroke prevention were included. A cluster randomization was performed based on two groups: (1) Control Group (CG) as usual clinical practice, and (2) Intervention Group (IG) with a mixed strategy: (a) Healthcare education, and (b) Use of a reminder calendar for taking the anticoagulant medication. Three visits took place: baseline and follow-up at 6 and 12 months. Compliance was measured by using electronic monitors (MEMS). Average adherence percentage (%; Average AP) and daily compliance (%; Daily AP) was calculated. A patient was considered adherent when AP was 80-100%. Results Six hundred and twenty-five patients completed the study (315 in the IG and 310 in the CG). Daily AP was 91.97% at 6 months and 91.05% after 12 months in the IG and 82.26% and 82.63% in the CG. Average adherence was 90.79% and 89.20% in the IG and 64.51% and 63.22% in the CG at 6 and 12 months, respectively. Significant differences were observed in the Daily AP and Average AP, with higher percentages in the IG. In the non-adherents group, the number of concomitant drugs, baseline, and 6 months SBP values, 6 and 12 months DBP values, and weight, total cholesterol, and LDL cholesterol were significantly higher. The number needed to treat (NNT) was 3.84 patients to prevent one non-adherence. Conclusions A mixed intervention, consisting of patient education and a simple calendar reminder of drug intake, is an effective strategy to improve dabigatran therapeutic adherence in patients with NVAF. The percentage of adherence with dabigatran was high.

BACKGROUND: Most hypertensive patients, despite a proper control of their cardiovascular risk factors, have cardiovascular complications, evidencing the importance of controlling and/or reversing target-organ damage. In this sense, endothelial dysfunction has been associated with the presence of cardiovascular risk factors and related cardiovascular outcomes. Since hypertension often clusters with other risk factors such as dyslipemia, diabetes and obesity, in this study we have investigated the effect of intensive multifactorial treatment on circulating vascular progenitor cell levels on high-risk hypertensive patients. DESIGN: We included108 hypertensive patients receiving intensive multifactorial pharmacologic treatment and dietary recommendations targeting blood pressure, dyslipemia, hyperglycemia and weight for 12 months. After the treatment period, blood samples were collected and circulating levels of endothelial (CD34+/KDR+, CD34+/VE-cadherin+) and smooth muscle (CD14+/endoglin+) progenitor cells were identified by flow cytometry. Additionally, plasma concentration of vascular endothelial growth factor (VEGF) was determined by ELISA. RESULTS: Most hypertensive patients (61±12 years, 47% men) showed cardiovascular parameters within normal ranges at baseline. Moreover, body mass index and the majority of the biochemical parameters (systolic and diastolic blood pressure, fasting glucose, total cholesterol, HDL-c, LDL-c, creatinine and hs-CRP) significantly decreased overtime. After 12 months of intensive treatment, CD34+/KDR+ and CD14+/endoglin+ levels did not change, but CD34+/VE-cadherin+ cells increased significantly at month 12 [0.9(0.05-0.14)% vs 0.05(0.02-0.09)% P<0.05]. However, VEGF plasma concentration decreased significantly overtime [89.1(53.9-218.7) vs [66.2(47.5-104.6) pg/mL, P<0.05]. CONCLUSIONS: Long-term intensive treatment in hypertensive patients further improves cardiovascular risk and increases circulating EPCs, suggesting that these cells could be a therapeutic target.

OBJECTIVE: To assess the quality of life (QOL) with rivaroxaban in patients with non-valvular atrial fibrilation (NVAF) related to therapeutic compliance. METHODS: Prospective, longitudinal, multicenter study was developed in 160 Spanish primary or specialized care centers. We included 412 patients treated with rivaroxaban, prescribed for stroke prevention. Three visits were conducted: baseline, 6 and 12 months. Compliance was measured by electronic monitoring systems. QOL was measured by a specific questionnaire. We calculated the percentage of compliance means, the percentage of daily compliers and the score of QOL. RESULTS: Three hundred and seventy patients finished the study (mean age 75.19 SD: 7.5 years). Daily compliance was 83.5% (CI 78.53-88.57%) (n = 309) and 80% (CI 74.65-85.35%) at 6 and 12 months, respectively. Average QOL rating was 112.85 (SD 29.31) in non-compliant and 111.80 (SD 29.31) in the compliant group (p = Not significant), and after 12 months of 124.67 (SD 30.78) and 83.47 (SD 26.44), respectively (p < 0.0001), with a decrease in the score compliers (p < 0.01) and an increase in non-compliant group (p < 0.05). A higher number of drugs consumed, as well as the number of diseases/conditions suffered, the older age of the patients and having been previously treated with VKA were associated with a higher overall score (worse QOL). CONCLUSIONS: QOL in NVAF patients treated with rivaroxaban improved significantly over the study group at the expense of compliers. A worse QOL was associated with pluripathology, polymedication, older patients and previous treatment with VKA.

Objetivo: Conocer el flujo de atención entre la atención primaria y la atención especializada (AE), así como los criterios usados para la derivación y posterior seguimiento, en relación con el paciente con hipertensión arterial (HTA) y diabetes mellitus tipo 2 (DM2). Diseño: Estudio descriptivo, transversal y multicéntrico. Emplazamiento: Se realizó un muestreo probabilístico, de conveniencia y estratificado por número de médicos en cada CCAA. Participaron 999 médicos, 78,1% (n = 780) especialistas en atención primaria (EAP), 11,9% (n = 119) especialistas en hipertensión y 10,0% (n = 100) especialistas en diabetes. Mediciones principales: Se emplearon 2 formularios de recogida de datos, autoadministrados vía online. Resultados: El 63,7% y el 55,5% de los EAP y el 79,8% y el 45,0% de la AE declararon la falta de un protocolo de coordinación entre los niveles para el manejo del paciente con HTA y DM2, respectivamente. El método de comunicación más frecuentemente usado entre los niveles asistenciales fue la hoja de derivación (94,6% en EAP y 92,4% en AE). Los principales criterios de derivación al médico de AE del paciente con HTA fueron la hipertensión resistente (80,9%) y la sospecha de hipertensión secundaria (75,6%), siendo la sospecha de DM específica (71,9%) y el embarazo (71,7%) en el paciente con DM2. Conclusiones: Aunque se observaron coincidencias en algunos aspectos de la práctica clínica habitual entre ambos niveles asistenciales, las discrepancias evidenciadas mostraron una escasa coordinación entre EAP y AE (AU)
Objective: To determine the flow of care for patients with type 2 diabetes mellitus (T2DM) and hypertension between primary care (PC) and specialized care (SC) in clinical practice, and the criteria used for referral and follow-up within the Spanish National Health System (NHS). Design: A descriptive, cross-sectional, multicenter study. Placement: A probability convenience sampling stratified by number of physicians participating in each Spanish autonomous community was performed. Nine hundred and ninety-nine physicians were surveyed, of whom 78.1% (n = 780) were primary care physicians (PCPs), while 11.9% (n = 119) and 10.0% (n = 100) respectively were specialists in hypertension and diabetes. Key measurements: was conducted using two self administered online surveys. Results: A majority of PCPs (63.7% and 55.5%) and specialists (79.8% and 45.0%) reported the lack of a protocol to coordinate the primary and specialized settings for both hypertension and T2DM respectively. The most widely used method for communication between specialists was the referral sheet (94.6% in PC and 92.4% in SC). The main reasons for referral to a specialist were refractory hypertension (80.9%) and suspected secondary hypertension (75.6%) in hypertensive patients, and suspicion of a specific diabetes (71.9%) and pregnancy (71.7%) in T2DM patients. Conclusions: Although results showed some common characteristics between PCPs and specialists in disease management procedures, the main finding was a poor coordination between PC and SC (AU)

BACKGROUND: The objective of this study was to assess the relationship between insulin resistance and apoptotic endothelial-derived microparticles (EMPs) in patients with chronic heart failure (CHF). METHODS: The study involved 300 CHF patients (186 males) aged 48-62 years with angiographically proven coronary artery disease and/or previously defined myocardial infarction. Insulin resistance was assessed by the homeostasis model assessment for insulin resistance (HOMA-IR). EMPs phenotype was determined by flow cytofluorometry. RESULTS: Depending on HOMA-IR cut-off point (over and <2.77 mmol/L×µU/mL) all patients were divided into two cohorts with (n=171) or without (n=129) IR, respectively. Circulating EMPs were higher in CHF patients with IR than in patients without IR. Interestingly, EMPs were directly related to NYHA functional class of CHF, HOMA-IR, NT-pro-BNP, hs-CRP and BMI. There was a significant association between the level of EMPs and HbA1c, gender (r=0.318, p<0.001 for male), age and smoking. On univariate and multivariate regression analysis we found that the NYHA class of CHF,NT-pro-BNP, hs-CRP, and left ventricular ejection fraction (LVEF) appeared to be independent predictors of increased circulatory apoptotic EMPs. The addition of HOMA-IR to the standard model (NYHA class CHF) improved the relative IDI by 19.9% for increased EMPs. For category-free NRI, 10% of events and 24% of non-events were correctly reclassified by the addition of HOMA-IR to the standard model for increased circulating EMPs. CONCLUSIONS: IR may be a contributing factor increasing circulating levels of apoptotic EMPs in non-diabetic CHF patients.

INTRODUCCIÓN: La buena comunicación entre niveles asistenciales es clave para el control de la hipertensión arterial. OBJETIVOS: Valorar la adecuación de la derivación del hipertenso desde atención primaria a atención especializada.como objetivos secundarios, valoramos el contenido del informe de derivación y la concordancia entre el motivo de derivación y el diagnóstico final. DISEÑO: Estudio observacional descriptivo. Emplazamiento: Estudio realizado a nivel nacional. PARTICIPANTES: Médicos de atención especializada que reciben pacientes hipertensos derivados de atención primaria. MEDICIONES PRINCIPALES: En una visita basal, el médico de atención especializada evaluó la calidad del informe de derivación y al paciente, y en visita final se establecen diagnóstico y tratamiento definitivos. RESULTADOS: Se incluyeron 1.769 sujetos, edad media de 62,4 (13,6) años, 45% mujeres. El tiempo medio de diagnóstico de hipertensión fue de 8,0 (7,7) años. Algo más de la mitad de los informes de derivación contienen información muy buena (5,4%; IC 4,3-6,5) o suficiente (50,7%; IC 48,4-53,0). Un 7,1% (IC 5,9-8,3) no indican causa de derivación. Fueron correctas el 74,7% de las derivaciones, y el 30% de estas fueron tardías. La concordancia entre las causas de derivación y los diagnósticos finales fueron bajas (índice Kappa 0,208). CONCLUSIONES: Una cuarta parte de los pacientes se derivan innecesariamente, y del 75% de los bien derivados, un 30% lo fueron tardíamente. Se debería mejorar la coordinación operativa entre los 2 niveles de atención en el área de hipertensión y del riesgo cardiovascular
INTRODUCTION: An adequate communication between levels of medical attention is the key point for optimal treatment and outcomes of the hypertensive population. AIMS: The aim of this study was to evaluate the adequacy of the hypertensive patients' derivation from Primary Care to Specialized Care. As secondary objectives, the information registered on the derivation report was assessed and concordance between derivation reason and final diagnosis was analysed. DESIGN: This is an observational, descriptive, multicentre study. Site: Study conducted at the national level. PARTICIPANTS: Specialty Care Physicians receiving hypertensive patients referred from primary care. Principal measurements: On the baseline visit, the specialist physicians assessed the quality of the derivation records and attended the patient. After the study, final diagnosis and treatment is suggested on the final visit. RESULTS: 1769 subjects were included, mean aged 62,4 (13,6) years, 45% female. Time of diagnosis of hypertension was 8,0 (7,7) years. More than the half of the derivation records contained very good information (5,4%; CI 4,3-6,5) or sufficient (50,7%; CI 48,4-53,0). In 7,1% (IC 5,9-8,3) derivation cause was not specified.74,7% of the derivations were considered as appropriate, though 30% were late. Concordance between derivation reasons and final diagnosis was low (kappa index 0,208). CONCLUSIONS: A quarter of the hypertensive population is unnecessary derived to Secondary Care and 30% of the appropriately derived was late. We should improve the interrelation of attention in the hypertension and cardiovascular area between the both attention levels

The beneficial effects of fish consumption in both children and adults are well known. However, the intake of methylmercury, mainly from contaminated fish and shellfish, can have adverse health effects. The study group on the prevention of exposure to methylmercury (GEPREM-Hg), made up of representatives from different Spanish scientific societies, has prepared a consensus document in a question and answer format, containing the group's main conclusions, recommendations and proposals. The objective of the document is to provide broader knowledge of factors associated with methylmercury exposure, its possible effects on health amongst the Spanish population, methods of analysis, interpretation of the results and economic costs, and to then set recommendations for fish and shellfish consumption. The group sees the merit of all initiatives aimed at reducing or prohibiting the use of mercury as well as the need to be aware of the results of contaminant analyses performed on fish and shellfish marketed in Spain. In addition, the group believes that biomonitoring systems should be set up in order to follow the evolution of methylmercury exposure in children and adults and perform studies designed to learn more about the possible health effects of concentrations found in the Spanish population, taking into account the lifestyle, eating patterns and the Mediterranean diet.

The aim of this study was to investigate the cognitive state in women and its relation to menopause and hypertension (HTN). The authors included 1034 women aged 47.13±15.71 years. The prevalence of HTN was 47.1%, with 67.8% of patients treated and 48.6% controlled. Cognitive impairment was higher among hypertensive menopausal (mini-Boston Naming Test: 7.4±3.1 vs 8.5±2.4, P<.001; Clock-Drawing Test: 5.2±2 vs 5.6±1.6, P<.01). Using logistic regression adjusted by age and education level, statistical differences were found in the results from the mini-Boston Naming Test between menopausal hypertensive vs menopausal normotensive women (odds ratio, 1.48; 95% confidence interval, 1.06-2.07; P=.021), and no difference between nonmenopausal hypertensive vs menopausal normotensive women (odds ratio, 0.89; 95% confidence interval, 0.51-1.57; P=.697). The P interaction between both groups was significant (P=.038). The possibility of alteration in cortical functions in menopausal hypertensive woman showed a relative increment of 48% (P=.021). The association between HTN and menopause increases the possibility of compromising the semantic memory by 50%.
