Levels of ankle-brachial index and the risk of diabetes mellitus complications.

OBJECTIVE: We sought to compare the association of categorized ankle-brachial index (ABI) with mortality and complications of diabetes in persons with no symptoms of peripheral arterial disease (PAD) and in primary cardiovascular disease prevention. RESEARCH DESIGN AND METHODS: This is a retrospective cohort study of persons with type 2 diabetes aged 35-85 years, from 2006 to 2011. Data were obtained from the Sistema d'Informació per al Desenvolupament de la Investigació en Atenció Primària (SIDIAPQ). Participants had an ABI measurement that was classified into six categories. For each category of ABI, we assessed the incidence of mortality; macrovascular complications of diabetes: acute myocardial infarction (AMI), ischemic stroke, and a composite of these two; and microvascular complications of this metabolic condition: nephropathy, retinopathy, and neuropathy. We also estimated the HRs for these outcomes by ABI category using Cox proportional hazards models. RESULTS: Data from 34 689 persons with type 2 diabetes were included. The mean age was 66.2; 51.5% were men; and the median follow-up was 6.0 years. The outcome with the highest incidence was nephropathy, with 24.4 cases per 1000 person-years in the reference category of 1.1≤ABI≤1.3. The incidences in this category for mortality and AMI were 15.4 and 4.1, respectively. In the Cox models, low ABI was associated with increased risk and was significant from ABI lower than 0.9; below this level, the risk kept increasing steeply. High ABI (over 1.3) was also associated with significant increased risk for most outcomes. CONCLUSIONS: The studied categories of ABI were associated with different risks of type 2 diabetes complications in persons asymptomatic for PAD, who were in primary cardiovascular prevention. These findings could be useful to optimize preventive interventions according to the ABI category in this population.

Estudio de los determinantes en las complicaciones del traumatismo encefalo craneal / sss

El T.E.C es una de las causas principales de incapacidad grave en algunos casos. La presente investigacion se inicio planteandose como objetivo general: determinar el tipo de atencion que tiene el paciente con T.E.C., por su familia en su domicilio y la educacion preventiva basica impartida por la profesional de enfermeria a estos pacientes y su familia a tiempo de alta. Los metodos e instrumentos utilizados fueron de observacion, entrevista con instrumentos estructurados, para el familiar y la profesional de enfermeria y guia de examen fisico semanal para el paciente...
