Health status and functional limitations in the elderly population of the University Region of Health of Puerto Rico: methodologic aspects and prevalence estimates

In order to plan the health services for the elderly population, it is necessary to quantify their health status and their functional capacity. In Puerto Rico, few epidemiological studies have been conducted regarding functional capacity and chronic diseases in the elderly population. One of the difficulties to undertake these studies is the high cost and risks to move this population for clinical exams, in addition to the methodology limitation of self-report in the elderly population. This study shows the use of logistic regression to estimate the prevalence of chronic diseases and functional capacity, when the observed data are not consisted with the planed sampling scheme. Four hundred and eighty-seven elderly persons (65 yr. and over) were interviewed in the municipalities of Canóvanas, Carolina, Loíza and Trujillo Alto in Puerto Rico, using a cross-sectional design. More than half of the elderly had visual problems (IC 95%: 54.8%, 63.8%), arthritis (IC 95%: 52.7%, 61.5%) and hypertension (IC 95%: 47.3%, 56.3%). In the case of hypertension, significant differences (p < 0.05) by sex were observed, where women reported a higher prevalence than men. One of the higher prevalences in the functional capacity status was with urine accidents. More than one-third of the population is estimated to have this problem (IC 95%: 34.7%, 43.4%). One-fourth of the population had limitations with going out for shopping (IC 95%: 23.9%, 31.9%) and using public and private transportation (IC 95%: 19.5%, 26.9%). We conclude that the applied methodology was consistent with the estimation presented in the literature and statistics from the Puerto Rico Health Department. However, it is necessary to continue assessing the design and analytical methodology, in order to undertake consistent and periodic evaluations of the elderly population.     

Trans-sclerally fixated PC-IOLs: six year of investigations

PURPOSE: To present the results of PC IOLs transscleral fixation to the ciliary sulcus in six years follow-up. MATERIAL AND METHODS: 152 eyes in 3 groups: 15 eyes with primary fixations of PC IOLs, 92 eyes with secondary fixations of PC IOLs and 45 eyes with secondary fixations of PC IOLs combined with penetrating keratoplasty. RESULTS: Postoperative corrected visual acuity was 0.5 or better in 32.2% of cases, the most common complications in our material was CME (9.9%), lens tilt (4.6%) and increase of IOP (3.95%). CONCLUSION: Transscleral fixation of PC IOLs offers good visual outcome with relatively low rate of complications and is recommended in cases with inadequate posterior capsule support.     

Long-term results of the Spanish trial on treatment and survival of patients with predominantly mild heart failure

A randomized open-label clinical trial was conducted to determine whether mortality, readmission, or quality of life differed between heart failure patients managed with captopril plus diuretics and those with digoxin plus diuretics. A total of 345 heart failure patients in New York Heart Association functional classes 2 and 3 without atrial fibrillation, dyspnea of bronchopulmonary origin, or hypertension not controlled with diuretics was randomized for digoxin (n = 175) or captopril (n = 170) treatment and followed up for a median of 4.5 years. Socioeconomic, demographic, electrocardiographic, echocardiographic, spirometric, and chest radiograph data were obtained at the initial examination. In a random sample of half the patients, ergometric, echocardiographic, and Holter records were obtained at entry and at 3 and 18 months. Patients were followed up for > or = 3 years. The end points were mortality, hospitalization for cardiac events, deterioration in quality of life, worsening of functional class, and need for digoxin or captopril in the captopril and digoxin groups, respectively. The trial had to be terminated prematurely owing to the difficulty in finding candidates free of angiotensin-converting enzyme (ACE)-inhibitor treatment. Baseline patient characteristics were similar in both groups. From the clinical point of view, only the 48-month mortality was relevantly lower (20.9 vs. 31.9%, respectively) among patients treated with captopril than that in those receiving digoxin (log rank test, p = 0.07). No statistically or clinically relevant differences were found in other end points or adverse effects. The results suggest but do not confirm the hypothesis that captopril treatment in mild to moderate heart failure might provide better long-term survival than digoxin.
