ABSTRACT: Delirium usually hardens care during hospitalization and increases morbidity during hospital stay and after discharge. The objective of this study was to describe the prevalence of delirium in elderly inpatients in a Buenos Aires hospital, its morbidity and mortality during hospital stay and the next 18 month follow-up. Patients aged 70 or older admitted to internal medicine unit between September 2005 and May 2006 were enrolled. Delirium was assessed with the Spanish version of Confusion Assessment Method. Demographic data, cause of admition and length of stay, destination after discharge and mortality were registered. A new evaluation was made 18 months after discharge. We evaluated 194 patients and 74 were excluded. Of the 120 included, 52 (43.3%) presented delirium. We found significant differences between patients with and without delirium in previous placement in nursing home (17.3% vs. 1.5%; p < 0.002), dementia (40.4% vs. 8.8%; p < 0.001), median activity of daily living (5 vs. 6; p < 0.001), length-of-stay (7 vs. 5; p = 0.04) and mortality rate (21.2% vs. 1.5%; p < 0.001). Evaluation 18 months later showed differences between patients with and without delirium in median of activity of daily living (1/6 vs. 5/6), patients living in nursing homes (27.5% vs. 7.9%), estimated survival 35.3% (CI 95%: 24-49%) at day 569 and 49% (CI 95%: 32.9-65.4%) at day 644. The difference between survival curves was statistically significant (p = 0.027). Delirium increases morbidity and mortality during hospital stay. Elderly with delirium are at risk of worsening disability and of becoming dependent after discharge and it is a risk factor for higher mortality during the following months after discharge.

ABSTRACT: Mild cognitive impairment (MCI) refers to persons who are slightly cognitively impaired for age but do not meet the criteria for dementia. MCI has been related to a pre-dementia stage of Alzheimer's disease (AD). However, other possible diagnoses such as cerebro-vascular disease, frontotemporal dementia or normal aging have been considered. Diagnosis, etiology and conversion to dementia are a source of ambiguity in MCI. The aim was to evaluate the opinion of experts on dementia and of general practitioners concerning MCI. A total of 24 experts from Argentina and Brazil (16 neurologists and 8 psychiatrists) and 30 general practitioners agreed to reply to a questionnaire on MCI (adapted from Dubois inventory, 2003). Of these, 92% of experts considered MCI as an ambiguous entity, not necessarily as a "pre-dementia" stage; 63% confirmed a tendency to worsen over the time and 83% of experts decided to initiate treatment using cholinesterase inhibitors, memantine and vitamin E. The opinion on MCI was that a priori it is not only an Alzheimer disease pre-dementia stage, but most of them consider the treatment against AD. MCI is a heterogeneous entity that should be classified as an open category and making it necessary to standardize definitions and design diagnosis guides to better understand Alzheimer disease pre-dementia stage.

ABSTRACT: Hypertension control is a difficult goal to achieve in common practice even when its benefits have been widely proved. We assessed the effectiveness of a Complex Antihypertensive Intervention Program in the Elderly (CAPE). A program trial of 500 elderly hypertensive patients was conducted. 250 were followed by primary care physicians and intervened by the CAPE and 250 received usual care. The program included an organizational change with the addition of an office where patients had their blood pressure measured, were appointed to join educational sessions and received verbal and printed advice before medical attendance. Data was systematically recorded in the electronic medical record which functioned as a physician reminder during the visit. Differences in systolic blood pressure level and in percentage of well-controlled (<140/90 mm Hg) patients between groups were measured after 12 months of follow-up. The difference of mean change in systolic blood pressure between groups was 7.1 mm Hg (95% confidence interval, 4-10 mm Hg). Sixty-seven percent of patients in the intervention group were well-controlled, as were 51% of patients in the control group (p < 0.001). Patients who attended educational sessions showed the lowest odd ratio (0.25; 95% confidence interval, 0.11-0.54) for blood pressure above 140/90 mm Hg in multivariate analysis after adjusting for age, sex, initial systolic blood pressure level, and changes in antihypertensive treatment. These results support the effectiveness of our complex intervention program. Routine clinical care of hypertension can be improved with simple strategies that go beyond pharmacotherapy, tending to overcome clinical inertia.

ABSTRACT: Currently, total hyperhomocysteinemia (tHHcy) is a well-known condition linked to a higher risk of vascular disease. Prevalence of HHcy increases in elderly persons as the risk associated with it persists. Because factors can be potentially reduced in the elderly, it is important to carry out epidemiologic studies of HHcy.
Previously we described the prevalence of hypertension control in an elder population; now, in an observational cross-sectional simple blind study, total homocysteine (tHcy) concentration was determined in 196 of 400 patients from the original cohort.
Mean Hcy concentration was 13.2 ,amol/L (95% confidence interval 12.4-14.0; range, 5.0 to 48.9); 15.0 ,imol/L for men and 12.3 pAmol/L for women. Mean serum folic acid levels were 4.9 + 3.1 ng/mL (range, 2.0 to 20.0 ng/mL), and vitamin B12 levels were 384.8 314.1 pg/mL (range, 48.0 to 1500.0 pg/mL). Taking into account the reference values established by the Third National Health and Nutrition Examination Survey III study, HHcy was detected in 69.8% of all the subjects evaluated. The study showed that 76.2% of the men and 66.4% of the women had high Hcy levels.
The very high prevalence of tHHcy in the elderly population, and the consequent risks associated with it suggest that although there are no trials that effectively prove the benefit of tHcy decrease, nutritional intervention is still justified.

ABSTRACT: Depression is a common disorder in the elderly population; with significant elevated rates in terms of morbidity and mortality. Nonetheless it continues to be a subdiagnosticated disease with poor outcomes due to lack in the effectiveness of follow up. We developed collaborative intervention programs for elderly people in primary care at Hospital Italiano de Buenos Aires designing a randomized controlled trial in the ambulatory setting. Patients were recruited for an initial comprehensive geriatric evaluation, and then randomly assigned to the program intervention (n=18) or usual care (n=19). At 6 months, 55.5% of intervention patients had a 50% or greater reduction in depressive symptoms from baseline compared with 31.5% of those on usual care. Although the reduction of the outcomes of depressive symptoms is not statistically significative, these are preliminary data. We believe there is a trend toward better results with regard to improvements in depressive symptoms in patients in the intervention group, and that this will achieve statistical significance as the number of subjects recruited is increased in the course of the trial.
