La retinografia ajuda a predir millor el risc del malalt hipertens

L'avaluació dels vasos de la retina és molt útil per al diagnòstic inicial d'hipertensió arterial, ja que ofereix informació per poder determinar millor el risc que tindrà el malalt hipertens i assignar, d'aquesta manera, el tractament més adequat. L'exploració del fons d'ull és el mètode més comú, però sovint es passa per alt degut a les seves condicions especials d'aplicació. Aquest treball proposa la retinografia com a mètode efectiu per fer aquesta avaluació.La evaluación de los vasos de la retina es muy útil en el diagnóstico inicial de la hipertensión arterial, pues ofrece información para pronosticar los factores de riesgo del paciente y asignar un tratamiento adecuado. El fondo de ojo es el método más común, pero debido a las condiciones especiales que requiere a menudo no se aplica. Este trabajo propone la retinografía como una alternativa efectiva

A pesar de la importancia que tiene el concepto de fragilidad, no existe un claro consenso sobre la definición operativa de dicho constructo. Mientras que algunos autores consideran que la presencia de discapacidad funcional forma parte de la definición de fragilidad, otros abogan por eliminar la discapacidad funcional de dicha definición argumentando que la presencia de discapacidad o dependencia funcional es una consecuencia de la fragilidad del individuo.Cada vez existe mayor evidencia de que la atención primaria a través de una valoración geriátrica integral consigue aumentar la supervivencia de estos pacientes en sus propios domicilios con una reducción de costes en comparación con la atención médica habitual

The dynamic behaviour of metabolic syndrome and its components in an eight-year population-based cohort from the Mediterranean

Síndrome X de resistència a la insulina; Síndrome metabòlica; ObesitatSíndrome X de resistencia a la insulina; Síndrome metabólico; ObesidadInsulin Resistance Syndrome X; Metabolic syndrome; ObesityBACKGROUND The significant rise in the prevalence of obesity coincides with the considerable increase in the prevalence of metabolic syndrome (MS) currently being observed worldwide. The components of MS are not static and their dynamics, such as the order of their occurrence, or the time of exposure to them are, as yet, unknown but could well be clinically relevant. Our objective was to study the dynamic behaviour of MS and its components in a large population-based cohort from a Mediterranean region. METHODS AND FINDINGS Our study employed a retrospective cohort (between January 1, 2005 and December 31, 2012) made up of individuals from the general population in a region in the northeast of Catalonia, Spain. Given that most of the explicative variables of the risk of having MS were time dependent and, therefore, the risk was not proportional, we used the Andersen-Gill (AG) model to perform a multivariate survival analysis and inferences were performed using a Bayesian framework. Thirty-nine percent of the participants developed MS; 44.6% of them with a single limited episode. Triglycerides and low HDL cholesterol, together with obesity, are components associated with the first occurrence of MS. Components related to the metabolism of glucose are associated with a medium risk of having a first episode of MS, and those related to blood pressure are associated with a lower risk. When the components related to blood pressure and the metabolism of glucose appear first, they determine the appearance of the first episode of MS. The variables concerning the persistence of MS are those that correspond to clinical conditions that do not have well-established drug treatment criteria. CONCLUSIONS Our results suggest that the components related to the metabolism of glucose and to high blood pressure appear early on and act as biomarkers for predicting MS, while the components related to obesity and dyslipidaemia, although essential for the development of MS, appear later. Making lifestyle changes reduces the conditions associated with the persistence of MS

Practical application of the ATOM study: Treatment efficacy of antihypertensive drugs in monotherapy or combination (ATOM metaanalysis according to PRISMA statement); tables for the use of antihypertensive drugs in monotherapy or combination

Background: The response to antihypertensive drugs is predictable. The absence of precise prescription recommendations to treat arterial hypertension (HT) lead to use drugs unable to reduce blood pressure (BP) to target values. We published ATOM study, in which we found significant differences in the ability to reduce BP between the different drugs. The objective of the study was to determine the expected decrease in blood pressure with the use of commercialized doses of the drugs commonly used in the treatment of HT in clinical practice, to avoid the use of drugs or combinations that even with the best response, are unable to obtain the necessary BP decrease to reach the goal. Methods: The analysis was based on the results of the ATOM study. To convert the mean doses of the different drugs and combinations in commercialized doses, the conclusions of the study by Law et al have been applied. Results: Based on the results, two tables were drawn, one for systolic BP and the other for diastolic BP, where the doses of the different drugs and combinations are classified according to the BP decrease that can be expected from them. In order to favor the use of the tables in clinical practice, the different drugs have been grouped in intervals of 10 millimeters of mercury (mmHg) for the decrease of the systolic BP and of 5 mmHg for the diastolic BP. Conclusions: Recommendations for the use of antihypertensive treatments should not be limited to pharmacological families. They should also consider differences between drugs or specific combinations. From the data of the ATOM study we have implemented tables that express the effect of the drugs commonly used in clinical practice and that should allow the clinicians to choose with care the treatment to use

Chronic Kidney Disease and Diabetic Retinopathy in Patients with Type 2 Diabetes

To explore the relationship between chronic kidney disease (CKD) and diabetic retinopathy (DR) in a representative population of type 2 diabetes mellitus (DM2) patients in Catalonia (Spain). This was a population-based, cross-sectional study. A total of 28,344 patients diagnosed with DM2 who had recorded ophthalmologic and renal functional examinations were evaluated. Data were obtained from a primary healthcare electronic database of medical records. CKD was defined as an estimated glomerular filtration ratio (eGFR) of <60 ml/min/1.73m 2 and/or urine albumin to creatinine ratio (UACR) ≥30 mg/g. DR was categorized as non-vision threatening diabetic retinopathy and vision threatening diabetic retinopathy. CKD was associated with a higher rate of DR [OR], 95% confidence interval [CI], 1.5 (1.4-1.7). When we analyzed the association between different levels of UACR and DR prevalence observed that DR prevalence rose with the increase of UACR levels, and this association was significant from UACR values ≥10 mg/g, and increased considerably with UACR values ≥300mg/g (Odds ratio [OR], 95% confidence interval [CI], 2.0 (1.6-2.5). This association was lower in patients with eGFR levels 44 to 30 mL/min/1.73m 2 [OR], 95% confidence interval [CI], 1.3 (1.1-1.6). These results show that CKD, high UACR and/or low eGFR, appear to be associated with DR in this DM2 population

Prevalence of chronic kidney disease in patients with type 2 diabetes in Spain: PERCEDIME2 study

Estudi transversal; Malaltia renal crònica; Diabetis mellitus tipus 2Estudio transversal; Enfermedad renal crónica; Diabetes mellitus tipo 2Cross-sectional study; Chronic kidney disease; Type 2 diabetes mellitusBackground: The objective of this study was to determinate the prevalence of chronic kidney disease (CKD) and the different stages of CKD in patients with type 2 diabetes mellitus (DM2) treated in primary care consults in Spain.Methods: A national cross-sectional study was performed in primary care consults. The following data were collected: demographic and anthropometric information; list of present cardiovascular risk factors (CVRF); previous macrovascular and microvascular disease history; physical examination and analytical data from the previous 12 months, including the urine albumin-creatinine ratio (UACR) and estimated glomerular filtration rate (eGFR) to evaluate renal function.Results: With regard to the patients, 27.9% presented some degree of CKD as follows: 3.5% with stage 1; 6.4% with stage 2; 16.8% with stage 3 (11.6% with stage 3A and 5.2% with stage 3B); and 1.2% with stages 4 and 5. The prevalence of patients with UACR ≥ 30 mg/g was 15.4% (13% microalbuminuria and 2.4% macroalbuminuria). Renal impairment (RI) was found in 206 patients (18%) of whom 133 patients (64.6%) was stage 3A, 60 patients (29.1%) was stage 3B and 13 patients (6.3%) stages 4 and 5. Among patients with RI, 143 patients (69.4%) had normoalbuminuria. The following variables were significantly associated with CKD: age; sex (women); systolic arterial blood pressure (SABP) ≥ 150 mmHg; and a previous history of cardiovascular disease.Conclusions: The results showed that the prevalence for any type of CKD was 27.9%. A systematic determination of UACR and eGFR may contribute to an early diagnosis, thus allowing intervention during the initial stages of the disease when treatment is more efficient

Comparison of different vascular risk engines in the identification of type 2 diabetes patients with high cardiovascular risk

Background: Some authors consider that secondary prevention should be conducted for all DM2 patients, while others suggest that the drug preventive treatment should start or be increased depending on each patient''s individual CVR, estimated using cardiovascular or coronary risk functions to identify the patients with a higher CVR. The principal objective of this study was to assess three different cardiovascular risk prediction models in type 2 diabetes patients. Methods: Multicentre, cross-sectional descriptive study of 3, 041 patients with type 2 diabetes and no history of cardiovascular disease. The demographic, clinical, analytical, and cardiovascular risk factor variables associated with type 2 diabetes were analysed. The risk function and probability that a cardiovascular disease could occur were estimated using three risk engines: REGICOR, UKPDS and ADVANCE. A patient was considered to have a high cardiovascular risk when REGICOR = 10 % or UKPDS = 15 % in 10 years or when ADVANCE = 8 % in 4 years. Results: The ADVANCE and UKPDS risk engines identified a higher number of diabetic patients with a high cardiovascular risk (24.2 % and 22.7 %, respectively) compared to the REGICOR risk engine (10.2 %). The correlation using the REGICOR risk engine was low compared to UKPDS and ADVANCE (r = 0.288 and r = 0.153, respectively//p < 0.0001). The agreement values in the allocation of a particular patient to the high risk group was low between the REGICOR engine and the UKPDS and ADVANCE engines (k = 0.205 and k = 0.123, respectively//p < 0.0001) and acceptable between the ADVANCE and UKPDS risk engines (k = 0.608). Conclusions: There are discrepancies between the general population and the type 2 diabetic patient-specific risk engines. The results of this study indicate the need for a prospective study which validates specific equations for diabetic patients in the Spanish population, as well as research on new models for cardiovascular risk prediction in these patients

Impact of chronic kidney disease on the prevalence of cardiovascular disease in patients with type 2 diabetes in Spain: PERCEDIME2 study

BACKGROUND: The presence of chronic kidney disease (CKD) in type 2 diabetes mellitus (T2DM) increases the risk of cardiovascular disease (CVD) regardless of the presence of traditional cardiovascular risk factors. There is controversy about the impact of each of the manifestations of CKD on the prevalence of CVD, whether it is greater with decreased estimated glomerular filtration rate (eGFR) or increased urine albumin creatinine ratio (UACR). METHODS: This study is a national cross-sectional study performed in primary care consults. We selected participants of both sexes who were aged 40 years or older, had been diagnosed with T2DM and had complete information on the study variables recorded in their medical records. The participants were classified according to eGFR : ≥ 60; 45-59; 30-44; 60 mL/min/1.73 m(2) those with eGFR between 30-44 mL/min/m(2), (OR = 2.3; 95% CI, 1.4-3.9); and eGFR < 30 mL/min/1.73 m(2) (OR = 4.1 95% CI 1.6-10.2) showed increased likelihood of having CVD. Participants with UACR ≥ 30 mg/g compared to participants with UACR < 30 mg/g increased significantly the likelihood of having CVD, especially with UACR above 300 mg/g, (OR = 1.6; 95% CI 1.1-2.4 for UACR = 30-299 mg/g; OR = 3.9; CI 1.6-9.5 for UACR ≥ 300 mg/g). CONCLUSION: The decrease in eGFR and increase in UACR are independent risk factors that increase the prevalence of CVD in participants with T2DM and these factors are independent of each other and of other known cardiovascular risk factors. In our study the impact of mild decreased eGFR in T2DM on CVD was lower than the impact of increased UACR. It is necessary to determine not only UACR but also eGFR for all patients with T2DM, both at the time of diagnosis and during follow-up, to identify those patients at high risk of cardiovascular complications

Effect of effervescent paracetamol on blood pressure: a crossover randomized clinical trial

OBJECTIVE: To evaluate the effect of effervescent paracetamol on office and ambulatory blood pressure (BP) compared with noneffervescent paracetamol in hypertensive patients. DESIGN: This was a multicenter open crossover randomized clinical trial. SETTING: Primary care centers in Catalonia and the Basque Country. PARTICIPANTS: Inclusion criteria were office BP 150/95¿mmHg or less and daytime ambulatory BP 140/90¿mmHg or less, stable pharmacologic or nonpharmacologic antihypertensive treatment, and concomitant chronic osteoarticular pain. INTERVENTIONS: Baseline randomized assignment to 3-week periods of effervescent paracetamol (1¿g three times a day) first and noneffervescent paracetamol later, or inversely, during a 7-week study period. At the start and end of each treatment period, 24-h ambulatory BP monitoring was performed. MAIN OUTCOME MEASURES: Differences in 24-h SBP between baseline and end of both treatment periods. The main analyses were performed according to the intention-to-treat principle. RESULTS: In intention-to-treat analysis, 46 patients were analyzed, 21 were treated with paracetamol effervescent and noneffervescent later, and 25 followed the opposite sequence. The difference in 24-h SBP between the two treatments was 3.99¿mmHg (95% confidence interval 1.35-6.63; P¿=¿0.004), higher in the effervescent paracetamol treatment period. Similarly, the per-protocol analysis showed a difference in 24-h SBP between the two groups of 5.04¿mmHg (95% confidence interval 1.80-8.28; P¿=¿0.004), higher in the effervescent paracetamol treatment period. Self-reported pain levels did not differ between groups and did not vary by treatment period. No serious adverse events were reported in either study arm. CONCLUSION: Effervescent paracetamol tablets are responsible for a significant daytime and overall increase in ambulatory 24-h SBP.
