Clinically Significant Depressive Symptoms and Associated Factors in Community Elderly Subjects From Sao Paulo, Brazil

Objectives: To determine the frequency of clinically significant depressive symptoms (CSDS) in a community sample of Brazilian elderly and to assess their relationship with sociodemographic factors, cognitive and functional impairment (CFI), and clinical diseases. Design: Cross-sectional study of a community-based sample of elderly subjects. Setting: City of Sao Paulo, State of Sao Paulo, Brazil. Participants: A total of 1,563 elderly subjects aged 60 years or older. Measurements: A 10-item scale for screening of depressive symptoms in elderly people (D-10), the Mini Mental State Examination, the Fuld Object Memory Evaluation, the Informant Questionnaire on Cognitive Decline in the Elderly, the Bayer Activities of Daily Living Scale, and a sociodemographic and clinical questionnaire. Results: The frequency of CSDS was 13.0%. Univariate analysis identified independent factors associated with these symptoms in our sample. Logistic regression analysis indicated that being female, brown skinned, previously depressed, having CFI, using psychotropics, and not practicing physical exercise were related to CSDS. On the other hand, being older, clinically sick, employed, or married were not associated with CSDS. Conclusions: Consistent with previous reports, female gender, lack of physical activity, and CFI were significantly associated with higher frequencies of CSDS. Further investigations are necessary to clarify the occurrence of depression and possible modifiable factors in developing countries such as Brazil. (Am J Geriatr Psychiatry 2009; 17: 582-590)

Systemic lupus erythematosus in the elderly: antimalarials in disease remission

To analyze the long-term antimalarials (AM) usage on elderly systemic lupus erythematosus (SLE) patients from 2002 to 2008. Fifty-seven consecutive SLE patients, a parts per thousand yen65 years, were enrolled. The patients were divided into groups A (disease remission) and B (disease activity: with clinical and/or laboratory alterations attributed to SLE activity, and/or using steroid and immunosuppressors). Forty-three patients (75.4%) were in group A. The mean age in groups A and B was, respectively, 69.8 +/- A 4.5 versus 67.8 +/- A 4.8 years (P = 0.210), with similar disease onset (46.9 +/- A 11.2 vs. 42.3 +/- A 11.6 years; P = 0.220). There was no difference in gender, ethnicity, and clinical previous manifestations. In 21 out of 57 cases (10 from group A and 11, group B, P < 0.001), AM had been suspended after 5.2 +/- A 1.3 years, because of its side effects (maculopathy). The disease remission was strongly associated to AM usage (OR 12.91; 95% CI 2.87-58.13). In summary, SLE remission was significantly associated with the long-term AM usage.

Performance of Brazilian long and short IQCODE on the screening of dementia in elderly people with low education

Background: Dementia screening in elderly people with low education can be difficult to implement. For these subjects, informant reports using the long (L) (26 items) and short (C) (16 items) versions of the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) can be useful. The objective of the present study was to investigate the performance of Brazilian versions of the IQCODE L, S and a new short version (SBr) (15 items) in comparison with the Mini-mental State Examination (MMSE) for dementia screening in elderly people with low education. Methods: Thirty-four patients with mild to moderate dementia, diagnosed according to ICD-10 criteria, and 57 controls were evaluated and divided into three groups based on their socioeconomic status and level of education. Patients were evaluated using the MMSE and the informants were interviewed using the IQCODE by interviewers blind to the clinical diagnosis. Results: Education was correlated with MMSE results (r = 0.280, p = 0.031), but not with the versions of the IQCODE. The performance of the instruments, evaluated by the ROC curves, was very similar, with good internal consistency (Cronbach`s alpha = 0.97). MMSE correctly classified 85.7% of the subjects while the three IQCODE versions (L, S and SBr) correctly classified 91.2% of the subjects. Conclusions: The long, short and the new short Brazilian IQCODE versions can be useful as a screening tool for mild and moderate patients with dementia in Brazil. The IQCODE is not biased by schooling, and it seems to be an adequate instrument for samples with low levels of education.

Obesity Decreases Time to Claudication and Delays Post-Exercise Hemodynamic Recovery in Elderly Peripheral Arterial Disease Patients

Background: Although obesity is usually observed in peripheral arterial disease (PAD) patients, the effects of the association between these diseases on walking capacity are not well documented. Objective: The main objectives of this study were to determine the effects of obesity on exercise tolerance and post-exercise hemodynamic recovery in elderly PAD patients. Methods: 46 patients with stable symptoms of intermittent claudication were classified according to their body mass index (BMI) into normal group (NOR) = BMI < 28.0 and obese or in risk of obesity group (OBE) = BMI >= 28.0. All patients performed a progressive graded treadmill test. During exercise, ventilatory responses were evaluated and pre- and post-exercise ankle and arm blood pressures were measured. Results: Exercise tolerance and oxygen consumption at total walking time were similar between OBE and NOR. However, OBE showed a lower claudication time (309 +/- 151 vs. 459 +/- 272 s, p = 0.02) with a similar oxygen consumption at this time. In addition, OBE presented a longer time for ankle brachial index recovery after exercise (7.8 +/- 2.8 vs. 6.3 +/- 2.6 min, p = 0.02). Conclusion: Obesity in elderly PAD patients decreased time to claudication, and delayed post-exercise hemodynamic recovery. These results suggest that muscle metabolic demand, and not total workload, is responsible for the start of the claudication and maximal exercise tolerance in PAD patients. Moreover, claudication duration might be responsible for the time needed to a complete hemodynamic recovery after exercise. Copyright (c) 2008 S. Karger AG, Basel

Fetal Cardiac Troponin T as a Marker of Poor Prognosis in Nonimmune Hydrops Fetalis

Objective: Severe fetal anemia and cardiac compromise are important causes of nonimmune hydrops fetalis, and fetal recovery also depends on the degree of fetal heart compromise. The aim of this study was to report the fetal cardiac troponin T (cTnT) levels in cases of nonimmune fetal hydrops. Methods: Fetal cTnT was analyzed on 7 occasions in 5 cases of nonimmune fetal hydrops ( twice in 2 cases). Results: In 3 of 4 fetuses in which intrauterine death occurred, fetal cTnT levels were increased. The only fetus that survived in this series showed decreased levels of cTnT before birth. Conclusion: Fetal cTnT levels may be a marker of fetal prognosis in cases of fetal hydrops. Copyright (C) 2009 S. Karger AG, Basel

Language impairment in euthymic, elderly patients with bipolar disorder but no dementia

Background: Neurocognitive impairment is known to occur in euthymic bipolar patients, but language alterations have not been thoroughly investigated. The aim of this study is to examine the performance in language tests of a sample of elderly patients with bipolar disorder. Methods: We studied 33 eurthymic elderly patients with bipolar disorder but no dementia and 33 healthy individuals, matched for age and education, who were compared in terms of their CAMCOG global score and its subitems. Results: The scores obtained in language-related abilities for patients and controls, respectively, were: language (total): 27.3 (1) and 28.5 (1), p < 0.0001)comprehension: 8.6 (0.5) and 8.9 (0.3), p = 0.006; production: 18.7 (1) and 19.6 (0.9), p = < 0.0001; abstraction: 6.8 (1.1) and 7.3 (0.7), p = 0.016; verbal fluency: 16.3 (4.3) and 19.6 (4.1), p = 0.003. Conclusion: A mild but significant impairment in language-related ability scores was detected when comparing patients and controls.

High prevalence of dementia among older adults from poor socioeconomic backgrounds in Sao Paulo, Brazil

Background: The aim of this study was to determine the prevalence of dementia in a socioeconomically disadvantaged population of older adults living in the city of Sao Paulo, Brazil. Methods: A cross-sectional one-phase population-based study was carried out among all residents aged >= 65 in defined census sectors of an economically disadvantaged area of Sao Paulo. Identification of cases of dementia followed the protocol developed by the 10/66 Dementia Research Group. Results: Of 2072 individuals in the study, 105 met the criteria for a diagnosis of dementia, yielding a prevalence of 5.1%. Prevalence increased with age for both men and women after age 75 years, but was stable from 65 to 74 years. Low education and income were associated with increased risk of dementia. Conclusions: The prevalence of dementia among older adults from low socioeconomic backgrounds is high. This may be partly due to adverse socioeconomic conditions and consequent failure to compress morbidity into the latter stages of life. The increasing survival of poorer older adults with dementia living in developing countries may lead to a rapid increase in the prevalence of dementia worldwide.

The association between osteoporosis and static balance in elderly women

This study aimed at answering the question: do people with high bone loss have greater postural instability? Groups were separated into group 1: women with normal bone mineral density, group 2: women with osteopenia, and group 3: women with osteoporosis. The balance was evaluated in four upright postural situations. Osteoporosis group had greater oscillation in the anteroposterior displacement in all situations compared to control group and the greatest mediolateral displacement in all situations compared to other groups. It is not known whether the presence of osteoporosis can be considered a factor aggravating the postural control. This study aimed at answering the question: do people with high bone loss have greater postural instability? This study was divided into three groups: group 1 (n = 20) consisting of women with normal bone mineral density, group 2 (n = 20) women with osteopenia, and group 3 (n = 20) women with osteoporosis. All the participants were submitted to evaluation of the balance using the Polhemus system in four upright postural situations. Osteoporosis group had greater oscillation in the anteroposterior displacement in all situations compared to control group. The osteoporosis group also showed the greatest mediolateral displacement in all situations compared to other groups. The results suggest that osteoporotic women had the worst balance, possibly due to the more pronounced body changes compared to non-osteoporotic women.

Why Not to Use Kidney Grafts From Elderly Donors

Background. Kidney transplantation is widely recognized as the best treatment in patients who require renal replacement therapy. Although considered a clinical and surgical triumph, it is also a source of frustration because of lack of donor organs and the growth of waiting lists. Strategies need to be developed to increase the supply of organs. One measure is use of expanded criteria for donation. Objective. To evaluate the effect of donor age on cadaver graft survival. Materials and Methods. We reviewed the medical records for 454 patients who underwent kidney transplantation with cadaver donors from April 1987 to December 2003. Results. Donor age had a significant effect on kidney transplant survival. Survival of grafts from donors aged 16 to 40 years (mean, 143.30 months) was significantly greater compared with that of grafts from donors older than 40 years (66.46 months) (P = .005). The HLA matching and cold ischemia time did not significantly affect transplant survival (P = .98 and P = .16, respectively). Conclusions. Kidneys from cadaver donors older than 40 years significantly compromised graft survival, generating a negative effect via early return of recipients to waiting lists and increasing the rate of repeat transplantation, risk of death, and unnecessary costs.

Stem cell transplants for patients with relapsed/refractory leukaemia

Purpose of review Today the indication for allogeneic stem cell transplantation for a high-risk leukaemia in first remission is well defined by most centres. In patients with primary refractory leukaemia the indication is controversially discussed. Similarly patients with relapse and advanced disease have a poor prognosis with chemotherapy, but also with transplantation. Finally more elderly patients with comorbidities seek help from transplantation, most of them in advanced and otherwise refractory disease. The results are reviewed. Recent findings The role of alloimmunity in the control of leukaemia has been defined and pretransplant conditioning treatment could be reduced to less intensive protocols. Graft-versus-leukaemia reactions have been demonstrated with the transfusion of donor lymphocytes. Using nonmyeloablative regimens allogeneic stem cell transplantation could be offered to elderly patients, the majority of patients with acute myeloid leukaemia and myelodysplastic syndromes. The use of antibodies and radio-immunotherapy has improved the treatment of lymphoid malignancies. Cord blood transplants have shown improved results with double transplants. The superiority of maternal donors indicates a role of the donor`s immune repertoire. Summary Taking advantage of alloimmune reactions and reduced intensity conditioning allogeneic stem cell transplantation has become successful even in elderly and fragile patients. The combination of molecular monitoring, targeted therapy and transplantation as a form of immunotherapy may improve the results of leukaemia treatment further.

EFFECT OF FLUID AND FOOD INTAKE ON THE BODY COMPOSITION EVALUATION OF ELDERLY PERSONS

Background: Several studies have shown that liquid and food intake interfere with the evaluation of body composition in adults. However, since there are no reports about this interference in the elderly population, the need to fast for this evaluation may be dispensable. Objectives: The objective of the present study was to assess the influence of liquid and solid food on the measurement of body composition by bioelectrical impedance analysis (BIA) and by dual energy X-ray absorptiometry (DXA). Design: Forty-one male volunteers aged 62 to 87 years participated in the study. The subjects were submitted to evaluation of body composition by DXA and BIA under fasting conditions and 1 hour after the ingestion of breakfast (500 ml of orange juice and one 50 g bread roll with butter). Results: There was no significant difference in the variables fat-free mass (FFM) or fat mass (FM) between the fasting condition and the evaluation performed 1 hour after the meal as measured by BIA or DXA. There was also no significant difference when the same variables were compared between methods. Conclusion: In the present study, the ingestion of 500 ml orange juice and of one bread roll with butter by elderly subjects did not affect the results of the parameters of body composition determined by BIA or DXA. Thus, these exams could be performed without the rigor of fasting, often poorly tolerated by the elderly.

THE EFFECT OF DIFFERENT VOLUMES OF ACUTE RESISTANCE EXERCISE ON ELDERLY INDIVIDUALS WITH TREATED HYPERTENSION

Scher, LML, Ferriolli, E, Moriguti, JC, Scher, R, and Lima, NKC. The effect of different volumes of acute resistance exercise on elderly individuals with treated hypertension. J Strength Cond Res 25(4): 1016-1023, 2011-Acute resistance exercise can reduce the blood pressure (BP) of hypertensive subjects. The aim of this study was to evaluate the effect of different volumes of acute low-intensity resistance exercise over the magnitude and the extent of BP changes in treated hypertensive elderly individuals. Sixteen participants (7 men, 9 women), with mean age of 68 6 5 years, performed 3 independent randomized sessions: Control (C: 40 minutes of rest), Exercise 1 (E1: 20 minutes, 1 lap in the circuit), and Exercise 2 (E2: 40 minutes, 2 laps in the circuit) with the intensity of 40% of 1 repetition maximum. Blood pressure was measured before (during 20 minutes) and after each session (every 5 minutes during 60 minutes) using both a mercury sphygmomanometer and a semiautomatic device (Omrom-HEM-431). After that, 24-hour ambulatory blood pressure monitoring was performed (Dyna-MAPA). Blood pressure decreased during the first 60 minutes (systolic: p < 0.01, diastolic: p < 0.05) after all exercise sessions. Only the highest volume session promoted a reduction of mean systolic 24-hour BP and awake BP (p, 0.05) after exercise, with higher diastolic BP during sleep (p, 0.05). Diastolic 24-hour BP and both systolic and diastolic BP during sleep were higher after E1 (p, 0.05). Concluding, acute resistive exercise sessions in a circuit with different volumes reduced BP during the first 60 minutes after exercise in elderly individuals with treated hypertension. However, only the highest volume promoted a reduction of mean 24-hour and awake systolic BP.

Anti-mullerian hormone is the best predictor of poor response in ICSI cycles of patients with endometriosis

Purpose: To correlate ovarian reserve (OR) markers with response in assisted reproduction techniques (ART) and determine their ability to predict poor response among patients with endometriosis (EDT). Methods: We evaluated ART cycles of 27 women with EDT and 50 with exclusive male factor. Basal follicle stimulating hormone (FSH) and anti-mullerian hormone (AMH) levels were determined. Ovarian response to gonadotropin stimulation was assessed and correlation coefficients calculated between the variables and reserve markers. Areas under the curve (AUC) determined ability of tests to predict poor response. Results: AMH was significantly correlated with response in both groups and it was the only marker with significant discriminative capacity to predict poor response among EDT (AUC = 0.842; 95% CI: 0.651-0.952) and control group (AUC = 0.869; 95% CI: 0.743-0.947). Conclusion: Infertile patients with endometriosis can benefit from the pre-therapeutic assessment of OR markers. However, regardless of disease presence, only AMH predicts poor response to stimulus.
