[Oral anticoagulation therapy in the elderly population with atrial fibrillation. A review article].

Aging is an important risk factor for patients with atrial fibrillation. The estimated prevalence of atrial fibrillation in patients aged ≥80 years is 9-10%, and is associated with a four to five fold increased risk of embolic stroke, and with an estimated increased stroke risk of 1.45-fold per decade in aging.

[Advanced organ failure in the elderly. Some issues from a geriatrics, palliative medicine and bioethics perspectives].

Objective: To analyze the literature as regards the knowledge, skills and attitudes that these disciplines can provide in improving technical, ethical and human quality health care in the elderly with advanced organ failure, multimorbidity, frailty and progressive dementia.

Material And Methods: A comprehensive review focused on available references on the interrelationship between geriatric medicine and palliative medicine, education in bioethics, prognostic tools, functional status, and the humanization of health care.

Results: Advance care planning, comprehensive geriatric assessment, the study of the values of the patient and their introduction in decision-making process, as well as the need to promote moral, care, and healthcare organizational ethics, are essential elements to achieve this objective.

[Subsyndromal delirium in elderly patients: a systematic review].

In this systemic review, the articles published between 1990 and November 2012 on subsyndromal delirium (SSD), and specifically those with reference to geriatric patients, were analysed. In SSD, symptoms from the three nuclear domains of delirium (cognitive, circadian and higher order thinking) are simultaneously present, with mild to moderate severity. Although the search for these clinical characteristics is a useful guide, there are no universally accepted diagnostic criteria for SSD.

Endoscopic localization of colorectal cancer: study of its accuracy and possible error factors.

Introduction: accurate preoperative localization of colorectal cancer (CRC) is very important, with a wide range of published error rates.

Aims: to determine accuracy of endoscopic localization of CRC in comparison with preoperative computed tomography (CT). To analyse variables that could be associated with a wrong endoscopic localization.

[Breast cancer screening: current status].

The currently available scientific evidence attests that mammographic screening and quality treatment have been able to reduce mortality attributable to breast cancer. Although screening is not without risks, population-based screening has clear advantages over opportunistic detection. Following the Council of the European Union's "Recommendations on cancer screening", all the regional Autonomous Communities in Spain have screening programs that, in general, follow the same guidelines.
