El objetivo de este trabajo fue conocer la frecuencia y la manera en que las plantas medicinales son empleadas por las gestantes del Centro de Salud Viña Alta del distrito de La Molina. En el estudio participaron veintiuna gestantes, quienes respondieron una encuesta, validada por expertos, sobre el uso de plantas medicinales. Se demostró que el 86,00 % de las gestantes utilizaron plantas medicinales, y que 67,00 % no consultó con un médico sobre su empleo. La manera más frecuente de consumo de las plantas medicinales fue la vía oral, en forma de infusiones. Las plantas medicinales más utilizadas fueron manzanilla, perejil, eucalipto, boldo, aloe, menta y ruda; y algunas de ellas mostraron efecto teratogénico, estimulante uterino, abortivo, entre otros. Es necesario conocer la cantidad real y la manera más frecuente en que las gestantes consumen las plantas medicinales, con la finalidad de clasificar estos productos de acuerdo al nivel de seguridad que ofrecen y promover el uso racional de la medicina tradicional para contribuir en la salud pública.

Aims: To estimate dementia prevalence and describe the etiology of dementia in a community sample from the city of São Paulo, Brazil. Methods: A sample of subjects older than 60 years was screened for dementia in the first phase. During the second phase, the diagnostic workup included a structured interview, physical and neurological examination, laboratory exams, a brain scan, and DSM-IV criteria diagnosis. Results: Mean age was 71.5 years (n = 1,563) and 58.3% had up to 4 years of schooling (68.7% female). Dementia was diagnosed in 107 subjects with an observed prevalence of 6.8%. The estimate of dementia prevalence was 12.9%, considering design effect, nonresponse during the community phase, and positive and negative predictive values. Alzheimer's disease was the most frequent cause of dementia (59.8%), followed by vascular dementia (15.9%). Older age and illiteracy were significantly associated with dementia. Conclusions: The estimate of dementia prevalence was higher than previously reported in Brazil, with Alzheimer's disease and vascular dementia being the most frequent causes of dementia. Dementia prevalence in Brazil and in other Latin American countries should be addressed by additional studies to confirm these higher dementia rates which might have a sizable impact on countries' health services.

In the context of the current COVID-19 pandemic, higher morbidity and mortality have been reported in older adults. This age group presents physiological changes and its own clinical conditions such as frailty, dementia, among others., Objective: To describe the characteristics of COVID-19 patients, both over and under 80 years old, by conducting a systematic review of the literature describing case reports, and to summarize and critically assess these characteristics., Methods: Systematic review. The study was registered on the Registry of Health Research Projects (PRISA) of the Peruvian National Institute of Health (code EI00000631). Five electronic databases (Scopus, PubMed, PubMed Central, LILACS, and SCIELO) were systematically searched during the period between December 31, 2019 and April 16, 2020. The search focused on case reports, case studies, and case series of older people with COVID-19 infection aged over or under 80 years. When selecting the cases, priority was given to clinical and epidemiological profile, laboratory and imaging patterns, and comprehensive geriatric evaluation., Results: 1,149 articles were identified; after applying the filters, a total of 15 publications of case reports and complete records of 27 older adults were obtained. The most frequent age group was between 60 to 69 years old. There is little literature regarding case reports of older adults aged over 80 years. The most frequent parameters were hypertension, fever, cough, respiratory distress, ground-glass opacification in chest radiography and tomography. Furthermore, decrease in PaO 2 /FiO 2 ratio and lymphocytes, and increase in C-reactive protein and Interleukin 6 were observed., Conclusions: This systematic review found little available information of patients under 80 years old, and far less for those over 80 years old, and an absence of comprehensive geriatric assessment., Competing Interests: Disclosure: The authors report no conflicts of interest.

Background: Multiple markers are used to assess frailty and vulnerability, conditions associated with the development of chemotherapy toxicity (CTT). However, there is still no consensus on which condition has stronger association with this adverse effect of chemotherapy in the elderly., Objectives: To evaluate the association between frailty and vulnerability with the development of CTT in oncogeriatric patients., Design, Setting, and Participants: Through a retrospective cohort, a secondary database of 496 male oncogeriatric military patients treated at the Geriatrics Service of the Naval Medical Centre of Peru during 2013-2015 was analyzed., Measurements: With prior informed consent, the presence of frailty, assessed by Fried Phenotype; and vulnerability, assessed by the Vulnerable Elders Survey-13 (VES-13) and G-8, was determined. The follow-up of patients in chemotherapy was performed every 8 weeks, to determine the development of CTT (according to the Common Terminology Criteria for Adverse Events v4.0). In addition, we included sociodemographic characteristics, medical background information and functional assessment variables. The data collected was encoded and imported into STATA v14.0 statistical package for analysis. Multivariate analysis was performed using crude and adjusted Cox regression models. The reported measure was the hazard ratio (HR) with their respective 95% confidence intervals (95%CI)., Results: The average age was 79.2 ± 4.3 years. 129 (26.01%) developed CTT during follow-up. Similarly, 129 older adults (26.01%) were positive for frailty according to Fried phenotype; 101 (20.36%) were positive for vulnerability with VES-13, and 112 (22.58%) with G-8. In the adjusted Cox model, by type of cancer and adverse effects, a statistically significant association was found between the 3 scales evaluated and the development of CTT, with the Fried Phenotype as the scale with the strongest association (HR=2.01; 95%CI: 1.04-4.90)., Conclusions: The frailty and vulnerability in the elderly are conditions associated with the development of CTT. The Fried phenotype was the scale with the most significant association with the outcome studied., Competing Interests: The authors disclose no conflict of interest.

Objective: The aim of this study was to investigate the effectiveness of a modified version of the Duke Somatic Algorithm Treatment for Geriatric Depression (STAGED) in a Brazilian sample of older patients with major depression. Besides, we aimed to investigate possible baseline predictive factors for remission in this sample., Methods: Sixty-seven depressed individuals were treated according to STAGED over 24 weeks in a prospective cohort design with follow-up. All patients had criteria for major depression and were at least 60 years of age at baseline enrollment., Results: During this follow-up, 56 patients could be classified in remitted or not remitted group, 42.85% reached remission, and 57.14% did not reach remission. These results are even better than those found in the original study, probably due to the lower baseline depression severity of our sample. When baseline characteristics were compared between remitted and not remitted groups, scores of Mini Mental State Examination and Cambridge Cognitive Examination (CAMCOG) were the only variables with statistical significant difference (p < 0.05) between groups. Logistic regression analysis was carried out to try to predict remission and statistical significance (p < 0.05) was found only for baseline MMSE scores. It may mean that patients with mixed cognitive disorders and mood disorders have a worse course of depression., Conclusions: This version of STAGED seems to be a useful strategy for treatment of depression in late life. Baseline general cognitive performance might be useful to predict remission of depression in older patients with mild to moderate depression. Further research with different population characteristics should be conducted in order to evaluate its usefulness and feasibility in different settings., (Copyright © 2012 John Wiley & Sons, Ltd.)

Introduction: Neuroimaging has been widely used in studies to investigate depression in the elderly because it is a noninvasive technique, and it allows the detection of structural and functional brain alterations. Fractional anisotropy (FA) and mean diffusivity (MD) are neuroimaging indexes of the microstructural integrity of white matter, which are measured using diffusion tensor imaging (DTI). The aim of this study was to investigate differences in FA or MD in the entire brain without a previously determined region of interest (ROI) between depressed and non-depressed elderly patients., Method: Brain magnetic resonance imaging scans were obtained from 47 depressed elderly patients, diagnosed according to DSM-IV criteria, and 36 healthy elderly patients as controls. Voxelwise statistical analysis of FA data was performed using tract-based spatial statistics (TBSS)., Results: After controlling for age, no significant differences among FA and MD parameters were observed in the depressed elderly patients. No significant correlations were found between cognitive performance and FA or MD parameters., Conclusion: There were no significant differences among FA or MD values between mildly or moderately depressed and non-depressed elderly patients when the brain was analyzed without a previously determined ROI., (Copyright © 2012 Elsevier Ltd.

Objective: To compare the volume of the hippocampus and parahippocampal gyrus in elderly individuals with and without depressive disorders, and to determine whether the volumes of these regions correlate with scores on memory tests., Method: Clinical and demographic differences, as well as differences in regional gray matter volumes, were assessed in 48 elderly patients with depressive disorders and 31 control subjects. Brain (structural MRI) scans were processed using statistical parametric mapping and voxel-based morphometry. Cognitive tests were administered to subjects in both groups., Results: There were no between-group gray matter volume differences in the hippocampus or parahippocampal gyrus. In the elderly depressed group only, the volume of the left parahippocampal gyrus correlated with scores on the delayed naming portion of the visual-verbal learning test. There were also significant direct correlations in depressed subjects between the volumes of the left hippocampus, right and left parahippocampal gyrus and immediate recall scores on verbal episodic memory tests and visual learning tests. In the control group, there were direct correlations only between overall cognitive performance (as assessed with the MMSE) and the volume of right hippocampus, and between the total score on the visual-verbal learning test and the volume of the right and left parahippocampal gyrus., Conclusions: These findings highlight different patterns of relationship between cognitive performance and volumes of medial temporal structures in depressed individuals and healthy elderly subjects. The direct correlation between delayed visual-verbal memory recall scores with left parahippocampal volumes specifically in elderly depressed individuals provides support to the view that depression in elderly populations may be a risk factor for dementia., (Copyright © 2009 Elsevier Inc.

Objective: The purpose of the present study was to investigate the influence that education and depression have on the performance of elderly people in neuropsychological tests., Methods: The study was conducted at the Institute of Psychiatry, University of São Paulo School of Medicine, Hospital das Clínicas. All of the individuals evaluated were aged 60 or older. The study sample consisted of 59 outpatients with depressive disorders and 51 healthy controls. We stratified the sample by level of education: low = 1-4 years of schooling; high = 5 or more years of schooling. Evaluations consisted of psychiatric assessment, cognitive assessment, laboratory tests and cerebral magnetic resonance imaging., Results: We found that level of education influenced all the measures of cognitive domains investigated (intellectual efficiency, processing speed, attention, executive function and memory) except the Digit Span Forward and Fuld Object Memory Evaluation (immediate and delayed recall), whereas depressive symptoms influenced some measures of memory, attention, executive function and processing speed. Although the combination of a low level of education and depression had a significant negative influence on Stroop Test part B, Trail Making Test part B and Logical Memory (immediate recall), we found no other significant effects of the interaction between level of education and depression., Conclusion: The results of this study underscore the importance of considering the level of education in the analysis of cognitive performance in depressed elderly patients, as well as the relevance of developing new cognitive function tests in which level of education has a reduced impact on the results.

This is a study on burden of caregivers of patients with Alzheimer's disease attended at a Reference Center for Cognitive Disorders., Objective: To evaluate the profile and burden on caregivers of patients with Alzheimer's disease attended at a Reference Center for Cognitive Disorders., Methods: We collected demographic information and data on the relationship with the patient from caregivers, and measured burden with the Zarit scale. The patients were evaluated with the following scales: the Cambridge Cognitive Test (CAMCOG); Mini Mental State Examination, the Neuropsychiatric Inventory for neuropsychiatry symptoms, and Functional Activities Questionnaire - FAQ for functional impairment., Results: Of the 31 caregivers, 77.4% were female, predominantly, and daughters, having a mean age of 58.6 years, educational level of 8.1 years, 70% of caregivers co-resided with the patient and 71% did not work. The mean time as a caregiver was 3 years. Twenty-seven percent of the caregivers presented mild to severe burden. The variables presenting significant association with caregiver burden were scores on the NPI and CAMCOG., Conclusion: The social demographic characteristics of the sample were similar to those of studies performed in other countries. The average time as a caregiver and the frequency of caregivers with mild to intense burden were lower than those reported in international studies. Neuropsychiatric symptoms and severity of cognitive decline were the main factors associated to burden in this sample of mostly mild to moderate demented AD patients. Further studies are necessary to verify whether the burden is indeed less intense in our milieu.

Objectives: The objectives of this study were to describe the prevalence of neuropsychiatric symptoms of dementia in Alzheimer disease (AD) and cognitively impaired nondemented (CIND) subjects from a community-based Brazilian sample and to correlate these symptoms with severity of cognitive deficits., Method: A total of 1,563 randomly selected subjects were evaluated with the following screening tests: Mini-Mental Status Examination, Fuld Object Memory Evaluation, Informant Questionnaire on Cognitive Decline in the Elderly, and Activities of Daily Living-International Scale. Screen positives were submitted to a workup for dementia, physical and neurologic examination, cranial computed tomography or cerebral magnetic resonance imaging, the Cambridge Examination for Mental Disorders, Clinical Dementia Rating Scale (CDR), and the Neuropsychiatric Inventory (NPI). Diagnosis was made according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria., Results: Sixty patients with AD, 25 CIND, and 78 healthy elderly subjects were evaluated. Informants reported that 78.33% of patients with AD had one or more neuropsychiatric symptoms. Apathy (53.33%), depression (38.33%), sleep alterations (38.33%), and anxiety (25%) were the most prevalent disturbances in AD subjects. These disturbances were more prevalent in patients with AD than in the comparison group and CIND individuals. In the CIND group, the most frequent neuropsychiatric symptoms were anxiety and sleep alterations (both with 24%) followed by depression (16%). Total NPI scores were significantly different between AD and CIND groups, AD and comparison groups, and CIND and the comparison group. Apathy was the only neuropsychiatric symptom that was significantly different between the groups divided according to the CDR being more frequent in subjects with moderate to severe dementia., Conclusions: Neuropsychiatric symptoms seem to be as common in patients living in a developing country as they are in demented patients from the developed world. Indeed, the fact that some of our results are similar to other population-based studies may suggest that cultural factors play a minor role in the emergence of these symptoms, at least in a Latin American country like Brazil.
