- Clinical and laboratory characteristics associated with referral of hospitalized elderly to palliative care(2018) ARCANJO, Suelen Pereira; SAPORETTI, Luis Alberto; CURIATI, Jose Antonio Esper; JACOB-FILHO, Wilson; AVELINO-SILVA, Thiago JunqueiraObjective: To investigate clinical and laboratory characteristics associated with referral of acutely ill older adults to exclusive palliative care. Methods: A retrospective cohort study based on 572 admissions of acutely ill patients aged 60 years or over to a university hospital located in Sao Paulo, Brazil, from 2009 to 2013. The primary outcome was the clinical indication for exclusive palliative care. Comprehensive geriatric assessments were used to measure target predictors, such as sociodemographic, clinical, cognitive, functional and laboratory data. Stepwise logistic regression was used to identify independent predictors of palliative care. Results: Exclusive palliative care was indicated in 152 (27%) cases. In the palliative care group, in-hospital mortality and 12 month cumulative mortality amounted to 50% and 66%, respectively. Major conditions prompting referral to palliative care were advanced dementia (45%), cancer (38%), congestive heart failure (25%), stage IV and V renal dysfunction (24%), chronic obstructive pulmonary disease (8%) and cirrhosis (4%). Major complications observed in the palliative care group included delirium (p<0.001), infections (p<0.001) and pressure ulcers (p<0.001). Following multivariate analysis, male sex (OR=2.12; 95% CI: 1.32-3.40), cancer (OR=7.36; 95% CI: 4.26-13.03), advanced dementia (OR=12.6; 95% CI: 7.5-21.2), and albumin levels (OR=0.25; 95% CI: 0.17-0.38) were identified as independent predictors of referral to exclusive palliative care. Conclusion: Advanced dementia and cancer were the major clinical conditions associated with referral of hospitalized older adults to exclusive palliative care. High short-term mortality suggests prognosis should be better assessed and discussed with patients and families in primary care settings.
- Comprehensive geriatric assessment predicts mortality and adverse outcomes in hospitalized older adults(2014) AVELINO-SILVA, Thiago J.; FARFEL, Jose M.; CURIATI, Jose A. E.; AMARAL, Jose R. G.; CAMPORA, Flavia; JACOB-FILHO, WilsonBackground: Comprehensive Geriatric Assessment (CGA) provides detailed information on clinical, functional and cognitive aspects of older patients and is especially useful for assessing frail individuals. Although a large proportion of hospitalized older adults demonstrate a high level of complexity, CGA was not developed specifically for this setting. Our aim was to evaluate the application of a CGA model for the clinical characterization and prognostic prediction of hospitalized older adults. Methods: This was a prospective observational study including 746 patients aged 60 years and over who were admitted to a geriatric ward of a university hospital between January 2009 and December 2011, in Sao Paulo, Brazil. The proposed CGA was applied to evaluate all patients at admission. The primary outcome was in-hospital death, and the secondary outcomes were delirium, nosocomial infections, functional decline and length of stay. Multivariate binary logistic regression was performed to assess independent factors associated with these outcomes, including socio-demographic, clinical, functional, cognitive, and laboratory variables. Impairment in ten CGA components was particularly investigated: polypharmacy, activities of daily living (ADL) dependency, instrumental activities of daily living (IADL) dependency, depression, dementia, delirium, urinary incontinence, falls, malnutrition, and poor social support. Results: The studied patients were mostly women (67.4%), and the mean age was 80.5 +/- 7.9 years. Multivariate logistic regression analysis revealed the following independent factors associated with in-hospital death: IADL dependency (OR= 4.02; CI= 1.52-10.58; p= .005); ADL dependency (OR= 2.39; CI= 1.25-4.56; p= .008); malnutrition (OR= 2.80; CI= 1.63-4.83; p< .001); poor social support (OR= 5.42; CI= 2.93-11.36; p< .001); acute kidney injury (OR= 3.05; CI= 1.78-5.27; p< .001); and the presence of pressure ulcers (OR= 2.29; CI= 1.04-5.07; p= .041). ADL dependency was independently associated with both delirium incidence and nosocomial infections (respectively: OR= 3.78; CI= 2.30-6.20; p< .001 and OR= 2.30; CI= 1.49-3.49; p< .001). The number of impaired CGA components was also found to be associated with in-hospital death (p< .001), delirium incidence (p< .001) and nosocomial infections (p= .005). Additionally, IADL dependency, malnutrition and history of falls predicted longer hospitalizations. There were no significant changes in overall functional status during the hospital stay. Conclusions: CGA identified patients at higher risk of in-hospital death and adverse outcomes, of which those with functional dependence, malnutrition and poor social support were foremost.
- Initial findings of striatum tripartite model in OCD brain samples based on transcriptome analysis(2019) LISBOA, Bianca C. G.; OLIVEIRA, Katia C.; TAHIRA, Ana Carolina; BARBOSA, Andre Rocha; FELTRIN, Arthur Sant'Anna; GOUVEIA, Gisele; LIMA, Luzia; SANTOS, Ana Cecilia Feio dos; JR, David Correa Martins; PUGA, Renato David; MORETTO, Ariane Cristine; PEREIRA, Carlos Alberto De Braganca; LAFER, Beny; LEITE, Renata Elaine Paraizo; FERRETTI-REBUSTINI, Renata Eloah De Lucena; FARFEL, Jose Marcelo; GRINBERG, Lea Tenenholz; JACOB-FILHO, Wilson; MIGUEL, Euripedes Constantino; HOEXTER, Marcelo Queiroz; BRENTANI, HelenaObsessive-compulsive disorder (OCD) is a psychiatric disorder characterized by obsessions and/or compulsions. Different striatal subregions belonging to the cortico-striato-thalamic circuitry (CSTC) play an important role in the pathophysiology of OCD. The transcriptomes of 3 separate striatal areas (putamen (PT), caudate nucleus (CN) and accumbens nucleus (NAC)) from postmortem brain tissue were compared between 6 OCD and 8 control cases. In addition to network connectivity deregulation, different biological processes are specific to each striatum region according to the tripartite model of the striatum and contribute in various ways to OCD pathophysiology. Specifically, regulation of neurotransmitter levels and presynaptic processes involved in chemical synaptic transmission were shared between NAC and PT. The Gene Ontology terms cellular response to chemical stimulus, response to external stimulus, response to organic substance, regulation of synaptic plasticity, and modulation of synaptic transmission were shared between CN and PT. Most genes harboring common and/or rare variants previously associated with OCD that were differentially expressed or part of a least preserved coexpression module in our study also suggest striatum subregion specificity. At the transcriptional level, our study supports differences in the 3 circuit CSTC model associated with OCD.
- Repair of Oxidative DNA Damage, Cell-Cycle Regulation and Neuronal Death May Influence the Clinical Manifestation of Alzheimer's Disease(2014) SILVA, Aderbal R. T.; SANTOS, Ana Cecilia Feio; FARFEL, Jose M.; GRINBERG, Lea T.; FERRETTI, Renata E. L.; CAMPOS, Antonio Hugo Jose Froes Marques; CUNHA, Isabela Werneck; BEGNAMI, Maria Dirlei; ROCHA, Rafael M.; CARRARO, Dirce M.; PEREIRA, Carlos Alberto de Braganca; JACOB-FILHO, Wilson; BRENTANI, HelenaAlzheimer's disease (AD) is characterized by progressive cognitive decline associated with a featured neuropathology (neuritic plaques and neurofibrillary tangles). Several studies have implicated oxidative damage to DNA, DNA repair, and altered cell-cycle regulation in addition to cell death in AD post-mitotic neurons. However, there is a lack of studies that systematically assess those biological processes in patients with AD neuropathology but with no evidence of cognitive impairment. We evaluated markers of oxidative DNA damage (8-OHdG, H2AX), DNA repair (p53, BRCA1, PTEN), and cell-cycle (Cdk1, Cdk4, Cdk5, Cyclin B1, Cyclin D1, p(27Kip1), phospho-Rb and E2F1) through immunohistochemistry and cell death through TUNEL in autopsy hippocampal tissue samples arrayed in a tissue microarray (TMA) composed of three groups: I) ""clinical-pathological AD"" (CP-AD) - subjects with neuropathological AD (Braak >= IV and CERAD = B or C) and clinical dementia (CDR >= 2, IQCODE >= 3.8); II) ""pathological AD"" (P-AD) - subjects with neuropathological AD (Braak >= IV and CERAD = B or C) and without cognitive impairment (CDR 0, IQCODE < 3.2); and III) ""normal aging"" (N) - subjects without neuropathological AD (Braak <= II and CERAD 0 or A) and with normal cognitive function (CDR 0, IQCODE<3.2). Our results show that high levels of oxidative DNA damage are present in all groups. However, significant reductions in DNA repair and cell-cycle inhibition markers and increases in cell-cycle progression and cell death markers in subjects with CP-AD were detected when compared to both P-AD and N groups, whereas there were no significant differences in the studied markers between P-AD individuals and N subjects. This study indicates that, even in the setting of pathological AD, healthy cognition may be associated with a preserved repair to DNA damage, cell-cycle regulation, and cell death in post-mitotic neurons.
- Crash Risk Predictors in Older Drivers: A Cross-Sectional Study Based on a Driving Simulator and Machine Learning Algorithms(2023) SILVA, V. C.; DIAS, A. S.; GREVE, J. M. D.; DAVIS, C. L.; SOARES, A. L. D. S.; BRECH, G. C.; AYAMA, S.; JACOB-FILHO, W.; BUSSE, A. L.; BIASE, M. E. M. de; CANONICA, A. C.; ALONSO, A. C.The ability to drive depends on the motor, visual, and cognitive functions, which are necessary to integrate information and respond appropriately to different situations that occur in traffic. The study aimed to evaluate older drivers in a driving simulator and identify motor, cognitive and visual variables that interfere with safe driving through a cluster analysis, and identify the main predictors of traffic crashes. We analyzed the data of older drivers (n = 100, mean age of 72.5 ± 5.7 years) recruited in a hospital in São Paulo, Brazil. The assessments were divided into three domains: motor, visual, and cognitive. The K-Means algorithm was used to identify clusters of individuals with similar characteristics that may be associated with the risk of a traffic crash. The Random Forest algorithm was used to predict road crash in older drivers and identify the predictors (main risk factors) related to the outcome (number of crashes). The analysis identified two clusters, one with 59 participants and another with 41 drivers. There were no differences in the mean of crashes (1.7 vs. 1.8) and infractions (2.6 vs. 2.0) by cluster. However, the drivers allocated in Cluster 1, when compared to Cluster 2, had higher age, driving time, and braking time (p < 0.05). The random forest performed well (r = 0.98, R2 = 0.81) in predicting road crash. Advanced age and the functional reach test were the factors representing the highest risk of road crash. There were no differences in the number of crashes and infractions per cluster. However, the Random Forest model performed well in predicting the number of crashes.
- Transforming the invisible into the visible: disparities in the access to health in LGBT plus older people(2023) CRENITTE, Milton Roberto Furst; MELO, Leonardo Rabelo de; JACOB-FILHO, Wilson; AVELINO-SILVA, Thiago JunqueiraObjectives: To compare variables of access to healthcare between the LGBT+ population aged 50 and over and those non-LGBT+.Methods: A cross-sectional study was carried out in Brazil through a confidential online questionnaire. The use of the health system was characterized by the number of preventive tests performed and measured by the PCATool-Brasil scale (a 10-point scale in which higher scores were associated with better assistance in healthcare). The association between being LGBT+ and access to health was analyzed in Poisson regression models.Results: 6693 participants (1332 LGBT+ and 5361 non-LGBT+) with a median age of 60 years were included. In the univariate analysis, it was observed not only lower scores on the PCATool scale (5.13 against 5.82, p < 0.001), but a greater proportion of individuals among those classified with the worst quintile of access to healthcare (< 4 points), 31% against 18% (p < 0.001). Being LGBT+ was an independent factor associated with worse access to health (PR = 2.5, 95% CI 2.04-3.06). The rate of screening cancer, for breast, colon, and cervical cancer was also found to be lower in the LGBT+ population. Conclusion: Healthcare access and health service experiences were worse in the LGBT+ group than in their non-LGBT peers. Inclusive and effective healthcare public policies are essential to promote healthy aging for all.
- Postmortem Brains from Subjects with Diabetes Mellitus Display Reduced GLUT4 Expression and Soma Area in Hippocampal Neurons: Potential Involvement of Inflammation(2023) YONAMINE, Caio Yogi; PASSARELLI, Marisa; SUEMOTO, Claudia Kimie; PASQUALUCCI, Carlos Augusto; JACOB-FILHO, Wilson; ALVES, Venancio Avancini Ferreira; MARIE, Suely Kazue Nagahashi; CORREA-GIANNELLA, Maria Lucia; BRITTO, Luiz Roberto; MACHADO, Ubiratan FabresDiabetes mellitus (DM) is an important risk factor for dementia, which is a common neurodegenerative disorder. DM is known to activate inflammation, oxidative stress, and advanced glycation end products (AGEs) generation, all capable of inducing neuronal dysfunctions, thus participating in the neurodegeneration progress. In that process, disturbed neuronal glucose supply plays a key role, which in hippocampal neurons is controlled by the insulin-sensitive glucose transporter type 4 (GLUT4). We investigated the expression of GLUT4, nuclear factor NF-kappa B subunit p65 [NFKB (p65)], carboxymethyllysine and synapsin1 (immunohistochemistry), and soma area in human postmortem hippocampal samples from control, obese, and obese+DM subjects (41 subjects). Moreover, in human SH-SY5Y neurons, tumor necrosis factor (TNF) and glycated albumin (GA) effects were investigated in GLUT4, synapsin-1 (SYN1), tyrosine hydroxylase (TH), synaptophysin (SYP) proteins, and respective genes; NFKB binding activity in the SLC2A4 promoter; effects of increased histone acetylation grade by histone deacetylase 3 (HDAC3) inhibition. Hippocampal neurons (CA4 area) of obese+DM subjects displayed reduced GLUT4 expression and neuronal soma area, associated with increased expression of NFKB (p65). Challenges with TNF and GA decreased the SLC2A4/GLUT4 expression in SH-SY5Y neurons. TNF decreased SYN1, TH, and SYP mRNAs and respective proteins, and increased NFKB binding activity in the SLC2A4 promoter. Inhibition of HDAC3 increased the SLC2A4 expression and the total neuronal content of CRE-binding proteins (CREB/ICER), and also counterbalanced the repressor effect of TNF upon these parameters. This study revealed reduced postmortem human hippocampal GLUT4 content and neuronal soma area accompanied by increased proinflammatory activity in the brains of DM subjects. In isolated human neurons, inflammatory activation by TNF reduced not only the SLC2A4/GLUT4 expression but also the expression of some genes related to neuronal function (SYN1, TH, SYP). These effects may be related to epigenetic regulations (H3Kac and H4Kac status) since they can be counterbalanced by inhibiting HDAC3. These results uncover the improvement in GLUT4 expression and/or the inhibition of HDAC3 as promising therapeutic targets to fight DM-related neurodegeneration.
- Applicability of the Spoken Knowledge in Low Literacy Patients with Diabetes in Brazilian elderly(2016) SOUZA, Jonas Gordilho; APOLINARIO, Daniel; FARFEL, José Marcelo; JALUUL, Omar; MAGALDI, Regina Miksian; BUSSE, Alexandre Leopold; CAMPORA, Flávia; JACOB-FILHO, WilsonABSTRACT Objective To translate, adapt and evaluate the properties of a Brazilian Portuguese version of the Spoken Knowledge in Low Literacy Patients with Diabetes, which is a questionnaire that evaluate diabetes knowledge. Methods A cross-sectional study with type 2 diabetes patients aged ≥60 years, seen at a public healthcare organization in the city of Sao Paulo (SP). After the development of the Portuguese version, we evaluated the psychometrics properties and the association with sociodemographic and clinical variables. The regression models were adjusted for sociodemographic data, functional health literacy, duration of disease, use of insulin, and glycemic control. Results We evaluated 129 type 2 diabetic patients, with mean age of 75.9 (±6.2) years, mean scholling of 5.2 (±4.4) years, mean glycosylated hemoglobin of 7.2% (±1.4), and mean score on Spoken Knowledge in Low Literacy Patients with Diabetes of 42.1% (±25.8). In the regression model, the variables independently associated to Spoken Knowledge in Low Literacy Patients with Diabetes were schooling (B=0.193; p=0.003), use of insulin (B=1.326; p=0.004), duration of diabetes (B=0.053; p=0.022) and health literacy (B=0.108; p=0.021). The determination coefficient was 0.273. The Cronbach a was 0.75, demonstrating appropriate internal consistency. Conclusion This translated version of the Spoken Knowledge in Low Literacy Patients with Diabetes showed to be adequate to evaluate diabetes knowledge in elderly patients with low schooling levels. It presented normal distribution, adequate internal consistency, with no ceiling or floor effect. The tool is easy to be used, can be quickly applied and does not depend on reading skills.
- Glomerular filtration in the aging population(2022) NORONHA, Irene L.; SANTA-CATHARINA, Guilherme P.; ANDRADE, Lucia; COELHO, Venceslau A.; JACOB-FILHO, Wilson; ELIAS, Rosilene M.In the last decades, improvements in the average life expectancy in the world population have been associated with a significant increase in the proportion of elderly people, in parallel with a higher prevalence of non-communicable diseases, such as hypertension and diabetes. As the kidney is a common target organ of a variety of diseases, an adequate evaluation of renal function in the approach of this population is of special relevance. It is also known that the kidneys undergo aging-related changes expressed by a decline in the glomerular filtration rate (GFR), reflecting the loss of kidney function, either by a natural senescence process associated with healthy aging or by the length of exposure to diseases with potential kidney damage. Accurate assessment of renal function in the older population is of particular importance to evaluate the degree of kidney function loss, enabling tailored therapeutic interventions. The present review addresses a relevant topic, which is the effects of aging on renal function. In order to do that, we analyze and discuss age-related structural and functional changes. The text also examines the different options for evaluating GFR, from the use of direct methods to the implementation of several estimating equations. Finally, this manuscript supports clinicians in the interpretation of GFR changes associated with age and the management of the older patients with decreased kidney function.
- Impact of oral health on frailty syndrome in frail older adults(2023) VENDOLA, Maria Cecilia Ciaccio; JACOB-FILHO, WilsonObjective: This study aimed to correlate oral and general health in frail and non-frail older adults. Methods: This observational study included 52 older adults, of whom 35 were frail (Frail Group), and 17 were non-frail (Non-Frail Group), according to Fried's self-reported test addressing oral health variables, number of systemic diseases, and medications in use. The geriatric oral health assessment index was used to assess the oral hygiene of the groups. Results: The number of preserved teeth in dentulous older adults was significantly higher in the Non-Frail Group (p=0.048). No significant differences were observed between the two groups in the use of dental prostheses or in the detection of soft tissue lesions. Overall, 74.3% of the Frail Group had a ""bad"" geriatric oral health index score, which significantly differed from that of the Non-Frail Group (p=0.045). The numbers of systemic diseases and medicines used were higher in the Frail Group than in the Non-Frail Group (p<0.001), demonstrating the pathophysiological characteristics of multimorbidity and polypharmacy in frailty syndrome. Conclusion: The results showed a clear correlation between oral and general health conditions and frailty syndrome.
