In developing countries, cardiovascular risk factors are poorly controlled, leading to high prevalence of cerebrovascular diseases. The aim of the study was to evaluate the burden of white matter lesions in magnetic resonance through the Fazekas scale in a population aged 75 + years living in the community, and to investigate possible associations between vascular lesions, cardiovascular risk factors and cognitive status. Subjects were selected from a community-based study on brain aging conducted in Caeté (Minas Gerais state), Brazil. Overall, 177 participants (112 cognitively healthy, 36 with cognitive impairment-no dementia and 29 with dementia), being 108 women, aged 79.3 ± 3.8 years, with 3.1 ± 2.9 years of educational level, underwent a 3 Tesla magnetic resonance scanner with fluid attenuated image recovery acquisition. Severity of white matter lesions was assessed through the Fazekas scale. Severe white matter lesions were present in 31.1% of the whole sample and in 25.0% of the cognitively healthy individuals. A significant association was found between severe white matter lesions and cognitive impairment (OR = 2.20, 95% CI 1.17-6.53; p = 0.021), as well as with hypertension (OR = 1.92, 95% CI 1.03-7.39; p = 0.043). In conclusion, a high prevalence of severe white matter lesions was observed in this elderly Brazilian population sample, and white matter lesions were associated with hypertension and cognitive status. Importantly, the prevalence of white matter lesions was also high in cognitively healthy subjects.

Background: Mutations in GRN (progranulin) and MAPT (microtubule-associated protein tau) are among the most frequent causes of monogenic frontotemporal dementia (FTD), but data on the frequency of these mutations in regions such as Latin America are still lacking., Objective: We aimed to investigate the frequencies of GRN and MAPT mutations in FTD cohorts from 2 Brazilian dementia research centers, the University of Sao Paulo and the Federal University of Minas Gerais medical schools., Methods: We included 76 probands diagnosed with behavioral-variant FTD (n=55), semantic-variant Primary Progressive Aphasia (PPA) (n=11), or nonfluent-variant PPA (n=10). Twenty-five percent of the cohort had at least 1 relative affected with FTD., Results: Mutations in GRN were identified in 7 probands, and in MAPT, in 2 probands. We identified 3 novel GRN mutations (p.Q130X, p.317Afs*12, and p.K259Afs*23) in patients diagnosed with nonfluent-variant PPA or behavioral-variant FTD. Plasma progranulin levels were measured and a cutoff value of 70 ng/mL was found, with 100% sensitivity and specificity to detect null GRN mutations., Conclusions: The frequency of GRN mutations was 9.6% and that of MAPT mutations was 7.1%. Among familial cases of FTD, the frequency of GRN mutations was 31.5% and that of MAPT mutations was 10.5%.

Background: Population aging is a global phenomenon whose main consequence is the increase of chronic degenerative diseases, including dementia. The aim of this case-control study was to evaluate the laboratorial parameters lipid profile, cortisol, and apolipoprotein E (APOE) gene genotype, comparing cognitively healthy controls and subjects with cognitive impairment no dementia (CIND) and dementia in a group of elderly people., Methods: Three hundred and nine individuals enrolled in the Pietà Study (Brazil) were divided into three groups: control (n = 158), CIND (n = 92), and dementia (n = 59). Participants were interviewed, went through examination, and had blood samples taken., Results: Age and APOE showed significant differences among the groups, while sex and lipid profile did not. According to multivariate regression logistic analyses, higher cortisol levels, lower high-density lipoprotein (HDL-c) and very low-density lipoprotein (VLDL-c), presence of ε4 allele of APOE, and aging were associated with CIND and dementia., Conclusion: These laboratorial parameters are risk factors associated to CIND and dementia in the elderly people and should be investigated in order to develop strategies to prevent or delay the onset of dementia in the oldest-old populations., (© 2015 Wiley Periodicals, Inc.)

Chronic mania is an under-investigated condition and few reports have associated this disorder with an organic background. The present work examines Kraepelin's reliable description of chronic mania from a current behavioral neurology viewpoint. Kraepelin had described a cluster of symptoms that are now recognized as core manifestations of the behavioral variant frontotemporal dementia (bvFTD) clinical phenotype. We also carried out additional reviews of original manuscripts from Kraepelin's peers, in order to find any case reports that might fulfill the current diagnostic proposal for bvFTD. Even though we failed to find an ideal case, we found some scholars who seemed to agree that chronic mania should be considered a special form of dementia. The present work highlights, through historical data, the possible overlapping features between primary psychiatric disorders and neuropsychiatric symptoms secondary to neurodegenerative conditions.

Objective: To propose new criteria for expert selection for validation studies in nursing in Brazil., Methods: (a) Literature review on terms related to expertise and criteria for expert selection; and (b) development of new consensus criteria for expert selection and consensus building., Results: Definitions for the terms novice, advanced beginner, competent, proficient, and expert were found. In the second phase, criteria to rank the experts (junior, senior, and master) were developed and validated according to a score of 5-20., Conclusion and Implications for Nursing Practice: The new criteria valued clinical experience over academic experience. The use of these criteria by researchers in the country should reduce uncertainties, difficulties, and limitations imposed by the modification/current adaptation of already existing criteria., (© 2015 NANDA International, Inc.)

Objective: : To investigate the influence of patients' age on the delay between diagnosis and surgical treatment of proximal femoral fractures., Methods: : This is a retrospective study, con-ducted at a tertiary university hospital, including all patients admitted with proximal femoral fractures between March 2013 and March 2014. The participants were categorized into four groups according to age levels. The groups were compared according to demographics, comorbidities, fracture type, trau-ma circumstances, and time between diagnosis and surgical procedure., Results: : One hundred and sixty one patients were included, 37 adults and 124 elderly. Among adults, the mean delay between diagnosis and surgical procedure was 6.4±5.3 days; among elderly the delay was 9.5±7.6 days. There was a progressive increase in the delay from the young-adults group through the elderly individuals (Kruskal-Wallis: 13.7; p=0.003)., Conclusion: : In spite of being the patients most susceptible to complications due to surgical delay, the elderly individuals pre-sented the longest delays from admission to surgical treatment. Level of Evidence III, Retrospective Study.

Interleukin 6 (IL-6) is a pro-inflammatory cytokine upregulated in neurodegenerative contexts. The polymorphism IL-6 -174 G > C influences release levels of this cytokine. We aimed to evaluate the influence of IL-6 -174 G > C on global cognitive score of a group with cognitive impairment no dementia in one year of follow-up.Methods The subjects were categorized in two groups: short-term decline in global cognitive score and those with short-term stability or improvement. IL-6 174 G > C information were compared among these groups.Results We observed that individuals with cognitive impairment no dementia with GGlowergenotype were more frequent among global cognitive score non-decliners while carriers of at least one Chigherallele were more frequent in the group with global cognitive score decliners (p = 0.012; RR = 3.095 IC95%= 1.087-8.812).Conclusion These results suggest that the higher expression of IL-6 gene may be an independent risk factor for cognitive decline among individuals with cognitive impairment no dementia.

Background: There is limited information about the functional profile of behavioral variant frontotemporal dementia (bvFTD)., Objective: To compare direct and indirect assessments of activities of daily living (ADLs) in bvFTD and Alzheimer disease (AD) and their relationship with cognitive performance., Methods: In all, 20 patients with bvFTD, 30 patients with AD, and 34 normal controls (NCs), matched for age, education, and severity of dementia, completed the Direct Assessment of Functional Performance (DAFS-BR) and usual cognitive measures. The Disability Assessment for Dementia (DAD) was completed by caregivers., Results: In DAFS-BR, patients with bvFTD and AD had similar performance but lower than NCs. In DAD, there were no significant differences for effective performance, but patients with bvFTD had lower scores for initiation and planning/organization. Patients with bvFTD were less impaired than AD in cognition., Conclusion: Functional changes in bvFTD seem to be better documented by indirect measures., (© The Author(s) 2014.)

Background/aims: We aimed to compare caregiver burden and distress in behavioral-variant frontotemporal dementia (bvFTD) and Alzheimer's disease (AD) and to investigate which factors contribute to caregivers' burden and distress., Methods: Fifty patients and their caregivers were invited to participate. Among the patients, 20 had a diagnosis of bvFTD and 30 had AD. Caregivers and patients were statistically equivalent for age, sex, education and dementia severity according to Clinical Dementia Rating. The protocol included the Short Zarit Burden Inventory, the Neuropsychiatric Inventory (NPI), Disability Assessment for Dementia (DAD), the Cornell Scale for Depression in Dementia (CSDD), Addenbrooke's Cognitive Examination-Revised, the Executive Interview with 25 Items, Direct Assessment of Functional Status and the Geriatric Anxiety Inventory (GAI)., Results: In the NPI, caregivers of bvFTD patients reported a higher presence and severity of neuropsychiatric symptoms and caregiver distress compared to caregivers of AD patients. There was no significant difference in the perceived burden. In bvFTD, DAD and GAI scores were significantly correlated with burden, whereas in AD, burden was correlated with CSDD and NPI scores. Psychiatric symptoms were associated with distress in both groups., Conclusions: Caregivers of bvFTD patients experienced higher levels of distress than caregivers of AD patients. Patients' functional limitations were associated with burden of caregivers of bvFTD patients, whereas neuropsychiatric symptoms were associated with caregiver strain in both groups., (© 2015 S.

Background: Inflammation and cytokine production are a common finding in aging, which probably exert influence on cognitive and functional abilities in elderly people. Transforming-growth-factor beta 1 (TGF-β1) is an important multifunctional anti-inflammatory cytokine that displays immunomodulatory activities., Objective: This prospective investigation aimed to evaluate the TGF-β1 codon 10 T>C on functional and cognitive decline in subjects aged 75+ years., Methods: The Functional Activities Questionnaire evaluated the functional performance and the cognitive assessment was evaluated through brief cognitive tests, consisting of: the Mini-Mental State Examination, animal category fluency test, and picture drawings memory test. All tests were administered twice, with a one-year interval., Results: Carriers of Tlower allele showed significant short-term decline in cognitive and functional performance, while individuals with CChigher genotype of TGF-β1 codon 10 T>C remained stable or showed improvement., Conclusion: Our findings indicate that the lower production of TGF-β1 could predict a longitudinal functional and cognitive decline in oldest-old individuals.

Concepts from cognitive neuroscience strongly suggest that the prefrontal cortex (PFC) plays a crucial role in the cognitive functions necessary for creative thinking. Functional imaging studies have repeatedly demonstrated the involvement of PFC in creativity tasks. Patient studies have demonstrated that frontal damage due to focal lesions or neurodegenerative diseases are associated with impairments in various creativity tasks. However, against all odds, a series of clinical observations has reported the facilitation of artistic production in patients with neurodegenerative diseases affecting PFC, such as frontotemporal dementia (FTD). An exacerbation of creativity in frontal diseases would challenge neuroimaging findings in controls and patients, as well as the theoretical role of prefrontal functions in creativity processes. To explore this paradox, we reported the history of a FTD patient who exhibited the emergence of visual artistic productions during the course of the disease. The patient produced a large amount of drawings, which have been evaluated by a group of professional artists who were blind to the diagnosis. We also reviewed the published clinical cases reporting a change in the artistic abilities in patients with neurological diseases. We attempted to reconcile these clinical observations to previous experimental findings by addressing several questions raised by our review. For instance, to what extent can the cognitive, conative, and affective changes following frontal damage explain changes in artistic abilities? Does artistic exacerbation truly reflect increased creative capacities? These considerations could help to clarify the place of creativity-as it has been defined and explored by cognitive neuroscience-in artistic creation and may provide leads for future lesion studies.

A higher level of educational attainment constitutes a protective factor against cognitive decline in the elderly. Nevertheless, the elements underpinning this association are yet not fully understood., Objective: The primary aim of this study was to compare cognitively impaired illiterate elderly subjects with cognitively preserved counterparts, according to demographics, comorbidities, lifetime habits and APOE genotype., Methods: This is a cross-sectional analysis of the illiterate subset of participants (n=174) from the Pietà study, a community-based survey of successful brain aging conducted in Caeté (MG), Brazil. Subjects were categorized into three diagnostic groups: cognitively normal (CN), cognitive impairment no-dementia (CIND) and dementia. The groups were then compared according to selected variables., Results: Subjects with dementia were older and had an increased prevalence of reported stroke or transient ischemic attack. The three groups did not differ in relation to demographics, prevalence of comorbidities, socioeconomic level, previous occupation profile and APOE-ε4 allele frequency. Qualitatively evaluated lifetime habits, such as alcohol consumption, smoking and physical activity engagement were also similar across groups., Conclusion: No associations were found between cognitive impairment/dementia and the variables evaluated in this community-based sample of illiterate elderly., Competing Interests: Disclosure: The authors report no conflicts of interest.

Background: Staging scales for dementia have been devised for grading Alzheimer's disease (AD) but do not include the specific symptoms of frontotemporal lobar degeneration (FTLD)., Objective: To translate and adapt the Frontotemporal Dementia Rating Scale (FTD-FRS) to Brazilian Portuguese., Methods: The cross-cultural adaptation process consisted of the following steps: translation, back-translation (prepared by independent translators), discussion with specialists, and development of a final version after minor adjustments. A pilot application was carried out with 12 patients diagnosed with bvFTD and 11 with AD, matched for disease severity (CDR=1.0). The evaluation protocol included: Addenbrooke's Cognitive Examination-Revised (ACE-R), Mini-Mental State Examination (MMSE), Executive Interview (EXIT-25), Neuropsychiatric Inventory (NPI), Frontotemporal Dementia Rating Scale (FTD-FRS) and Clinical Dementia Rating scale (CDR)., Results: The Brazilian version of the FTD-FRS seemed appropriate for use in this country. Preliminary results revealed greater levels of disability in bvFTD than in AD patients (bvFTD: 25% mild, 50% moderate and 25% severe; AD: 36.36% mild, 63.64% moderate). It appears that the CDR underrates disease severity in bvFTD since a relevant proportion of patients rated as having mild dementia (CDR=1.0) in fact had moderate or severe levels of disability according to the FTD-FRS., Conclusion: The Brazilian version of the FTD-FRS seems suitable to aid staging and determining disease progression., Competing Interests: Disclosure: The authors report no conflicts of interest.

Purpose: This case study illustrates the use of the nursing process based upon the standardized nursing diagnoses approved by NANDA International (NANDA-I), and using the Nursing Outcomes Classification (NOC) and the Nursing Interventions Classification (NIC) in the care of a patient with pemphigus vulgaris (PV)., Data Sources: The published literature on PV and the experience and expertise of the authors in working with people with impaired skin integrity and PV were used to develop this case study., Data Synthesis: The accuracy of nursing diagnoses and appropriateness of the nursing interventions were supported by the positive health outcomes of the patient., Conclusion: Impaired skin integrity is a human response diagnosed by nurses, and early treatment is important due to the vulnerability of these patients., Implications for Nursing Practice: The case study contributes to nursing knowledge for professionals who care for patients with PV., (© 2013 NANDA International.)

Apathy is intimately associated with dementia. Unfortunately, its pathophysiology remains poorly understood. The motivational impairment that characterizes this disorder might share the same inflammatory mechanisms, as suggested by the sickness behavior theory., Objective: The primary aim of this study was to investigate the association between apathy symptoms and serum levels of tumor necrosis factor alpha (TNF-α) and its soluble receptors. Brain-derived neurotrophic factor (BDNF) levels were also analyzed since these have been associated with depression, a condition which shares abulic features with apathy., Methods: The sample consisted of 27 subjects with mild Alzheimer's disease or amnestic mild cognitive impairment, who were submitted to specific apathy evaluation using the Apathy Scale (AS) and provided blood samples for biomarker analysis. Participants were categorized into two groups according to median AS scores (17 points)., Results: Subjects with higher apathy symptoms (n=13) displayed higher levels of TNF-α soluble receptors (type 1: p=0.03; type 2: p=0.04). No other difference was found between groups., Conclusion: These findings point to the involvement of inflammatory mediators in the genesis of apathy symptoms, as suggested by the sickness behavior theory., Competing Interests: Disclosure: The authors report no conflicts of interest.

There are few studies describing the functional changes in behavioral variant frontotemporal dementia (bvFTD) and it is not clear which aspects of functionality are affected by the disease., Objective: The aim of the present investigation was to characterize the functional profile of patients previously diagnosed with bvFTD., Methods: The sample consisted of 31 patients diagnosed with bvFTD, who were compared to patients with Alzheimer's disease (AD) (n=31) and to healthy control subjects (NC) (n=34), matched for schooling and age. bvFTD and AD patients were matched by severity of dementia. The protocol included the Mini-Mental State Examination (MMSE), Geriatric Depression Scale (GDS), Direct Assessment of Functional Status (DAFS-BR), Functional Activities Questionnaire (PFAQ), Disability Assessment for Dementia (DAD) and the Clinical Dementia Rating scale (CDR)., Results: The group with bvFTD showed worse performance on Initiation and Planning/Organization in the DAD and on ability to feed oneself in the DAFS-BR, as well as higher scores on the PFAQ, suggesting greater dependence in the bvFTD group., Conclusion: The results suggest that individuals with bvFTD display greater functional impairment compared to AD patients with a similar degree of dementia severity and to healthy controls. Direct assessment of functionality proved unable to clearly differentiate between the dementia subtypes.

Introduction: Despite many advances in the characterization of the behavioral variant of frontotemporal dementia (bvFTD), the diagnosis of this syndrome poses a significant challenge, while delays or diagnostic mistakes may impact the proper clinical management of these patients., Objective: To describe the clinical profile at first evaluation of a sample of patients with bvFTD from a specialized outpatient neurological unit, with emphasis on the analysis of the delay between the onset of symptoms and diagnosis., Methods: We selected 31 patients that fulfilled international consensus criteria for possible or probable bvFTD. Patients' medical admission sheets were thoroughly reviewed., Results: Patients' mean age was 67.9±8.2 years; 16 (51.6%) were men. Mean number of years of formal education was 7.7±4.0 years. Mean age at onset was 62.2±7.7 years, indicating a mean of 5.8 years of diagnostic delay. Thirteen patients (41.9%) presented with initial behavioral complaints only, eleven patients (35.5%) had mixed behavioral and memory complaints, five patients (16.1%) presented with memory complaints only, and two patient (6.4%) had behavioral and speech problems. Nine patients (29%) were admitted with alternative diagnoses. Mean and standard deviation scores for the mini-mental state examination, animal category fluency and memory test for drawings (five-minute delayed recall) were 19.3±6.3, 8.3±4.1and 3.7±2.7, respectively., Conclusion: Most patients from this sample were evaluated almost six years after the onset of symptoms and performed poorly on both cognitive screening tests and functional evaluation measures., Competing Interests: Disclosure: The authors report no conflicts of interest.

Objective: To show data on the performance of healthy subjects in the Frontal Assessment Battery (FAB), correlating with gender, age, education, and scores in the Mini-Mental State Examination (MMSE)., Methods: Two hundred and seventy-five healthy individuals with mean age of 66.4 ± 10.6 years-old were evaluated. Mean total FAB scores were established according to the educational level., Results: Mean total FAB scores according to the educational level were 10.9 ± 2.3, for one to three years; 12.8 ± 2.7, for four to seven years; 13.8 ± 2.2, for eight to 11 years; and 15.3 ± 2.3, for 12 or more years. Total FAB scores correlated significantly with education (r=0.47; p<0.0001) and MMSE scores (r=0.39; p<0.0001). No correlation emerged between FAB scores, age, and gender., Conclusion: In this group of healthy subjects, the Brazilian version of the FAB proved to be influenced by the education level, but not by age and gender.

Objectives: Among several other factors, the neuro-toxic β-amyloid peptide (βAP)-induced inflammatory mechanisms have also been implicated in the pathogenesis of Alzheimer's dementia (AD). Cytokines have recently emerged as prime candidates underlying this immune reaction. The purpose of this study was to evaluate the inflammatory response of peripheral blood mono-nuclear cells (PBMC) in AD., Design: Cross-sectional (observational) study., Setting: Behavioral and cognitive neurology clinic of the Universidade Federal de Minas Gerais in Belo Horizonte, Brazil., Participants: AD patients (n=19), healthy elderly (n=19) and young (n=14) individuals., Measurements: Cytokine levels were assessed by enzyme-linked immuno-sorbent assay (ELISA) after exposing cells to a broad range of βAP concentrations (10(-4)-10(-10)M) as a stimulus. AD samples were weighed against leukocytes harvested from non-demented young and elderly subjects., Results: Cytokine production of PBMCs in the youth was characterized by low baseline levels when compared to cells from the older generation. In the aging population, AD cells were distinguished from the healthy elderly sub-group by an even higher basal cytokine secretion. The low resting concentration in young individuals was markedly increased after treatment with βAP, however cells from the elderly, irrespective of their disease status, showed unchanged cytokine release following βAP administration. Non-specific activation of PBMCs with anti-CD3/CD28 antibodies resulted in elevated interleukin (IL)-1β concentrations in AD., Conclusions: These results demonstrate a general over-production of cytokines and resistance to βAP in the old comparison group, with a more pronounced disruption/boosted pattern in AD. Our findings are in line with the hypothesis of "inflammaging", i.e. an enhanced inflammatory profile with normal aging and a further perturbed environment in AD. The observed cytokine profiles may serve as diagnostic biomarkers in dementia., (Copyright © 2011 Elsevier Inc. All rights reserved.)

Objectives: To present the methods and baseline characteristics of the Pietà study, a population-based survey investigating successful brain aging in the oldest-old., Method: The study was conducted in Caeté (MG), Brazil. In 2007, 1,251 individuals aged 75+ years were living in the city and were invited to participate. Participants responded to a general health questionnaire and were submitted to clinical, neurological, cognitive, psychiatric and functional evaluations. A subgroup was submitted to neuropsychological testing, blood tests and magnetic resonance of the skull. Individuals were classified as having cognitive impairment-no dementia, dementia, parkinsonism, psychiatric disorders or successful brain aging., Results: We evaluated 639 individuals (51.1% of the target population; 64% women), aged 81.4±5.2 years and with 2.7±2.6 years of schooling. Almost 30% of the elderly were illiterates and 82.1% belonged to middle/middle-low socioeconomic levels. Almost 50% were widows, but only 14.3% were living alone., Conclusion: The Pietà cohort is representative of the oldest-old Brazilian population. We believe the results of the study may contribute to increase our knowledge about healthy and pathological brain aging in the oldest-old.

No Brazilian version of a specific scale for evaluating apathy in dementia is available., Objectives: To introduce a translated version of the Apathy Scale (AS) for use with caregivers., Methods: The instrument was formally translated and then administered to the caregivers of a small sample of dementia patients, in order to assess scale comprehensibility and make final adjustments. The scale was subsequently administered to the caregivers of a second, independent sample of Alzheimer's disease (AD) patients. The content validity of the scale was tested by correlating the AS scores with the Neuropsychiatric Inventory (NPI) - apathy sub-score and Disability Assessment in Dementia (DAD) total scores., Results: The first sample consisted of eleven subjects with dementia, most of whom had AD. The second sample comprised twenty patients with probable or possible AD (10 with mild dementia), a mean age of 84.1±5.8 years, and 2.2±1.6 years of schooling. The AS scores correlated with both NPI-apathy sub-score (r=0.756, p=0.001) and DAD total scores (r=-0.793, p=0.0005)., Conclusions: The final version had good comprehensibility and correlated strongly with standardized apathy and functional activities of daily living measures., Competing Interests: Disclosure: The authors report no conflicts of interest.

Purpose: This case study illustrates nursing diagnoses and interventions for a man with leprosy., Data Sources: Data sources were published literature on the disease of leprosy, and the experience and expertise of the authors in working with people with leprosy., Data Synthesis: Data were synthesized using the standardized nursing languages of North American Nursing Diagnosis Association International and the Nursing Interventions Classification. The accuracy of the diagnoses and the appropriateness of the nursing interventions were supported by the positive health outcomes of the patient., Conclusions: Although leprosy has been eradicated in some countries, the risk of new cases is present anywhere that Mycobacterium leprae still exists. The recommended treatment of multibacilar polychemotherapy has lowered the rate of new cases in Brazil., Implications for Nursing Practice: Nurses need to incorporate evidence-based practice interventions for leprosy-based wound care, and nurses should encourage persons with leprosy to maintain regular medical care with multibacilar polychemotherapy.

Taking care of elderly demented individuals, especially when they present behavioral changes, can be very exhaustive for both family and caregivers. Generally, this leads to changes in the family lifestyle, and the caregiver must deal with a range of problems. Information on this topic in Latin America, including Brazil, remains scarce., Objective: To investigate the relationship between the presence of neuropsychiatric symptoms and the level of caregiver burden in a group of Brazilian elderly with dementia., Methods: The Brazilian versions of the Zarit Caregiver Burden Interview (ZBI) and of the Neuropsychiatric Inventory (NPI) were administered to a total of 83 family-caregivers of patients with dementia followed at a university-affiliated outpatient clinic. Pearson's correlations were calculated to measure the level of association between the scores on both instruments., Results: Among the caregivers, 83.1% were women, and had a mean age of 55.6±12.8 years. The ZBI scores ranged from 3 to 79 (mean=31.4). Patients' NPI scores ranged from 0 to 102 (mean=26.9), consistent with a significant degree of behavioral manifestations in most patients. A significant positive correlation was found between ZBI and NPI scores (r=0.402; p=0.000)., Conclusion: The presence and severity of behavioral manifestations assessed by the NPI were associated with a high level of caregiver burden in this sample of Brazilian elderly with dementia., Competing Interests: Disclosure: The authors report no conflicts of interest.

Apathy is considered the most frequent neuropsychiatric disturbance in dementia and its outcome is generally deleterious. Apathy can be related to a dysfunction of the anatomical-system that supports the generation of voluntary actions, namely the prefrontal cortex and/or the prefrontal-subcortical circuits. In Alzheimer's disease, pathological and neuroimaging data indicate that apathy is likely due to a dysfunction of the medial prefrontal cortex. Accordingly, in this review article, we propose a pathophysiological model to explain apathetic behavior in Alzheimer's disease, combining data from neuroimaging, neuropathology and experimental research on the role of orbito-frontal cortex, anterior cingulate cortex, basal ganglia and dopamine in decision-making neurobiology.

Objective: To investigate the prevalence of infection, disease and eventual institutional outbreak of tuberculosis in a psychiatric hospital using the PPD test, as well as testing for mycobacteria in material collected from the respiratory tree and using molecular tracking technique based on insertion sequence 6110 (IS6110)., Methods: Between February and August of 2002, PPD tests were given to 74 inpatients and 31 staff members at a psychiatric hospital in the city of Rio Verde, located in the state of Goiás, Brazil. In addition, respiratory tree material collected from the inpatients was submitted to testing for Mycobacterium tuberculosis., Results: Among the patients analyzed, mycobacteria were isolated from five (6.8%): four identified as M. tuberculosis and one as M. chelonae. The M. tuberculosis isolates were sensitive to isoniazid and rifampicin, and, when submitted to the restriction fragment length polymorphism/IS6110 technique, presented unique genetic profiles, totally distinct from one another, suggesting that all of the tuberculosis cases were due to endogenous reactivation. It was not possible to characterize this group of cases as an institutional outbreak. Performing the two-step tuberculin test in the patients, the infection rates were 23% and 31%, compared with 42% among staff members, who were submitted to the one-step test., Conclusion: The results indicate a high incidence of tuberculosis infection among inpatients and hospital staff, as well as a high occurrence of the disease among inpatients.

The objective of this research is to identify which nursing activities contained in the fluid management intervention proposed by the Nursing Intervention Classification (NIC) are realized and considered important by nurses, to attend patients who received fluid volume excess as a nursing diagnosis, as proposed by the North American Nursing Diagnoses Association (NANDA). Data were collected in three hospitals. The sample included 77 nurses, who chose the best alternative on a Likert scale, to indicate the realization of which of those actives they considered important and which activities are realized in their daily care practice. It was concluded that most of the nursing activities were always considered important and were always performed by the nurses. These activities were classified as independent and dependent.

During the last years, Nursing is seeking to classify its diagnoses, interventions/actions and outcomes. Here is presented one of the classifications of nursing interventions that was proposed by nurses of the University of Iowa in 1987, the Nursing Interventions Classifications (NIC) as well as the reasons os its creation, in order to contribute to the dissemination of one of the most advanced proposals for classifying nursing interventions.

The present study aimed to reflect on the importance of body language through the identification of what a graduate nursing group knew about this topic. We analyzed the contents of reports from which five categories emerged: concept, function, importance, meaning and forms of body language manifestation. The group valued body language as a complex way of interpersonal interaction that sometimes occurs out of our control and of which we have little conscience. It has the function of expressing feelings, emotions and transmitting messages whose meanings are influenced by context. Body language knowledge increases our professional perception and it is one more instrument to improve nursing assistance quality.

This study aimed at verifying the defining characteristics of the nursing diagnosis "Fluid Volume Excess" proposed by NANDA. Data collection was carried out within a specialized Cardiology health care setting where the 29 patients were selected by two expert nurses. The conclusion showed consonance of opinions between the two professionals in regard to the identification of nine patients with diagnosis and 20 without this type of diagnosis. The identified defining characteristics appeared in different percentages considering the studied patients.
