- Direct Measurements of Abdominal Visceral Fat and Cognitive Impairment in Late Life: Findings From an Autopsy Study(2019) NISHIZAWA, Aline; CUELHO, Anderson; FARIAS-ITAO, Daniela S. de; CAMPOS, Fernanda M.; LEITE, Renata E. P.; FERRETTI-REBUSTINI, Renata E. L.; GRINBERG, Lea T.; NITRINI, Ricardo; JACOB-FILHO, Wilson; PASQUALUCCI, Carlos A.; SUEMOTO, Claudia K.Background: The relationship between cognitive impairment and abdominal visceral is controversial. Moreover, all studies so far used imaging studies to evaluate visceral fat and this association has not been described yet using autopsy material, which allows the direct quantification of abdominal fat. We aimed to investigate the association between direct measurements of abdominal visceral fat and cognitive impairment in an autopsy study. Methods: In this cross-sectional study, we collected information on sociodemographics, cardiovascular risk factors, and cognitive status from subjects aged 50 or older at time of death in a general autopsy service in Brazil. Abdominal visceral fat was obtained in natura by the dissection of perirenal, mesenteric, omental, and mesocolon fat. The associations of total abdominal visceral fat with cognitive impairment [clinical dementia rating (CDR) score >= 0.5] and CDR-sum of boxes (CDR-SB) were evaluated using logistic regression and negative binomial regression models, respectively. All analyses were adjusted for height, age, sex, education, hypertension, diabetes mellitus, stroke, smoking, alcohol use, and physical inactivity. In addition, we compared the discrimination of visceral fat, body mass index (BMI), and waist circumference (WC) measurements in predicting cognitive impairment. Results: We evaluated 234 participants (mean age = 71.2 +/- 12.9 years old, 59% male). Abdominal visceral fat was inversely associated with cognitive impairment (OR = 0.46, CI = 0.30; 0.70, p < 0.0001) and with CDR-SB scores (beta = 0.85, 95% CI = 1.28; 0.43, p < 0.0001). When we compared the area under the ROC curve (AUC), visceral fat (AUC = 0.754), BMI (AUC = 0.729), and WC (AUC = 0.720) showed similar discrimination in predicting cognitive impairment (p = 0.38). Conclusion: In an autopsy study, larger amount of directly measured abdominal visceral fat was associated with lower odds of cognitive impairment in older adults.
- Apolipoprotein E genotypes were not associated with intracranial atherosclerosis: a population-based autopsy study br(2023) PARADELA, Regina Silva; FARIAS-ITAO, Daniela Souza; LEITE, Renata E. P.; PASQUALUCCI, Carlos A.; GRINBERG, Lea T.; NASLAVSKY, Michel Satya; ZATZ, Mayana; NITRINI, Ricardo; JACOB-FILHO, Wilson; SUEMOTO, Claudia KimieBackground: Apolipoprotein E gene (APOE) 64 allele is associated with a higher risk of carotid atherosclerosis, but less is known about the association of APOE with intracranial atherosclerotic disease (IAD). We aimed to investigate the association of APOE alleles with IAD in a cross-sectional autopsy study.Methods: We measured the stenosis in the 12 arteries of the Circle of Willis using postmortem morphometric measurements. The APOE polymorphism was determined by real-time polymerase chain reaction. We assessed the association between APOE polymorphism and IAD using regression models adjusted for sociodemographic and clinical variables. We also verified the modifier effect of age, sex, and race on this association. We stratified the analysis by age group to investigate the possibility of attrition bias.Results: In 400 participants (mean age = 73.2 +/- 12.3 years old, 51% female, and 64% White), IAD was evaluated in 4,504 artery segments. APOE- 64 was not associated with IAD nor with the number of artery stenosis compared to non-APOE- 64 carriers. Sociodemographic variables did not modify this relationship. Among participants older than 70 years, there was a trend towards an association between APOE allele 64 and a lower stenosis index in the middle cerebral artery, suggesting attrition bias related to the APOE- 64 effect on mortality.Conclusions: APOE alleles were not associated with IAD in this population-based autopsy study. Lower stenosis in older participants suggests the possibility of attrition bias.
conferenceObject Inflammation in the Perivascular Adipose Tissue is Associated With Coronary Artery Disease: An Autopsy Study(2015) FARIAS, Daniela S.; PASQUALUCCI, Carlos A.; NISHIZAWA, Aline; SILVA, Luiz F.; CAMPOS, Fernanda M.; SILVA, Karen C.; CUELHO, Anderson; LEITE, Renata E.; FERRETTI-REBUSTINI, Renata E.; GRINBERG, Lea T.; FARREL, Jose M.; JACOB-FILHO, Wilson; SUEMOTO, Claudia K.- Apolipoprotein E 62 allele is associated with lower risk of carotid artery obstruction in a population-based autopsy study(2023) PARADELA, Regina Silva; FARIAS-ITAO, Daniela Souza; LEITE, Renata E. P.; PASQUALUCCI, Carlos A.; GRINBERG, Lea T.; NASLAVSKY, Michel Satya; ZATZ, Mayana; NITRINI, Ricardo; JACOB-FILHO, Wilson; SUEMOTO, Claudia KimieIntroduction: Apolipoprotein E (APOE) 64 allele has been associated with higher carotid atherosclerosis risk, while the APOE-62 seems to decrease this risk. Data from autopsy studies, where carotid arteries can be evaluated in their full extension, is scarce. Therefore, we investigated the association between APOE alleles and direct morphometric measurements of carotid atherosclerosis in an autopsy study with an admixed sample.Methods: We measured the intima-media thickness (IMT) and stenosis of the common (CCA) and internal carotid (ICA) arteries. The APOE polymorphisms were determined by real-time polymerase chain reaction. Participants were classified into three groups according to the APOE alleles (62, 63, and 64). We evaluated the association between APOE groups and carotid atherosclerosis using adjusted regression models and included interaction terms of APOE alleles with age, sex, and race. Results: We evaluated 1,850 carotid artery samples from 185 participants (mean age=75 & PLUSMN;12 years old, 55% female, and 71% White). The APOE-62 group (n=17) had a lower carotid obstruction and a lower number of severe stenoses (& GE; 70%). Having at least one 64 allele (n=51) was not associated with carotid atherosclerosis. APOE alleles were also not associated with carotid IMT. Age, sex, and race did not modify these relationships.Conclusion: APOE-62 carriers had a lower percentage of carotid obstruction and less severe stenosis. APOE-64 was not related to a higher risk of carotid atherosclerosis in this cross-sectional population-based autopsy study.
- Association between adiposity and systemic atherosclerosis: a protocol of a cross-sectional autopsy study(2016) NISHIZAWA, Aline; SUEMOTO, Claudia Kimie; FARIAS, Daniela Souza; CAMPOS, Fernanda Marinho; SILVA, Karen Cristina Souza da; CUELHO, Anderson; LEITE, Renata Elaine Paraizo; FERRETTI-REBUSTINI, Renata Eloah de Lucena; GRINBERG, Lea Tenenholz; FARFEL, Jose Marcelo; JACOB-FILHO, Wilson; PASQUALUCCI, Carlos AugustoIntroduction: Adiposity has been associated with atherosclerosis in clinical studies. However, few autopsy studies have investigated this association, and they had only examined the coronary artery disease. Moreover, most studies had small sample sizes and were limited to middle-aged or young adults. Our aim is to investigate the association between adiposity and systemic atherosclerosis in an autopsy study. Methods and analysis: A sample of 240 deceased with 30 years or more will be evaluated. The sample size was calculated using the lowest correlation coefficient found in previous studies (r=0.109), assuming a power of 90% and alpha=0.05. We will collect information about sociodemographics, frequency of previous contact of the deceased's next of kin and cardiovascular risk factors. We will measure neck, waist and hip circumferences, weight, height and abdominal subcutaneous tissue thickness, and then we will calculate the body mass index, waist-to-hip ratio, waist-to-height ratio and body shape index. We will also weigh the pericardial and abdominal visceral fat, the heart, and we will measure the left ventricular wall thickness. We will evaluate the presence of myocardial infarction, the degree of atherosclerosis in the aorta, carotid, coronary and cerebral arteries and plaque composition in carotid, coronary and cerebral arteries. For each individual, we will fix arterial and adipose tissue samples in 10% formalin and freeze another adipose tissue sample at -80 degrees C for future studies. Ethics and dissemination: Ethical approval was granted by the Ethics Committee of University of Sao Paulo Medical School, Brazil. Results will be submitted for publication in a peer-reviewed journal.
- The Potential Role of Selection Bias in the Association Between Coronary Atherosclerosis and Cognitive Impairment(2023) YAHAGI-ESTEVAM, Maristella; FARIAS-ITAO, Daniela Souza; LEIT, Renata Elaine Paraizo; RODRIGUEZ, Roberta Diehl; PASQUALUCCI, Carlos Augusto; NITRINI, Ricardo; JACOB-FILHO, Wilson; POWER, Melinda C.; SUEMOTO, Claudia KimieBackground: Coronary atherosclerosis assessed in vivo was associated with cognitive impairment; however, conflicting findings have been reported in autopsy samples. Objective: Our aims were to assess the association between atherosclerotic stenosis in the coronary arteries and cognitive impairment and to investigate the possibility of selection bias in an autopsy study. Methods: Coronary arteries were collected, and the largest luminal stenosis was measured. Sociodemographic, clinical, and cognitive information were reported by a reliable next-of-kin. The association was tested using logistic and linear regressions adjusted for sociodemographic and clinical variables. We restricted the sample to individuals that were born in 1935 or earlier and stratified the analysis by cause of death to investigate the role of selection bias. Results: In 253 participants (mean age = 78.0 +/- 8.5 years old, 48% male), stenosis was not associated with cognitive impairment (OR = 0.85, 95%CI = 0.69; 1.06, p = 0.15). In individuals who were born before 1936 in the absence of cardiovascular disease as the cause of death, greater stenosis was associated with cognitive impairment (OR = 4.02, 95%CI = 1.39; 11.6, p = 0.01). On the other hand, this association was not present among those born in 1935 or earlier who died of cardiovascular diseases (OR = 0.83, 95%CI = 0.60; 1.16, p = 0.28). Conclusion: We found that higher coronary stenosis was associated with cognitive impairment only in individuals born in 1935 or earlier and who had not died from cardiovascular diseases. Selection bias may be an important issue when investigating risk factors for chronic degenerative diseases in older individuals using autopsy samples.
- Morphometric measurements of systemic atherosclerosis and visceral fat: Evidence from an autopsy study(2017) NISHIZAWA, Aline; SUEMOTO, Claudia K.; FARIAS-ITAO, Daniela S.; CAMPOS, Fernanda M.; SILVA, Karen C. S.; BITTENCOURT, Marcio S.; GRINBERG, Lea T.; LEITE, Renata E. P.; FERRETTI-REBUSTINI, Renata E. L.; FARFEL, Jose M.; JACOB-FILHO, Wilson; PASQUALUCCI, Carlos A.Background Morphometric measurements of systemic atherosclerosis and direct quantification of visceral fat are only possible using materials from autopsy studies. However, the few autopsy studies that have investigated the association of visceral fat with atherosclerosis had small sample sizes and focused on coronary arteries of young or middle-aged White subjects. We aimed to investigate the association of pericardial fat (PF) and abdominal visceral fat (AVF) with atherosclerosis in the aorta, coronary, carotid, and cerebral arteries in a large autopsy study. Materials and methods We evaluated deceased subjects aged 30 years or above. We dissected and weighted the PF and the AVF and evaluated the atherosclerotic burden in the aorta, as well as the carotid, coronary, and cerebral arteries using morphometric measurements. We also investigated the interaction of PF and AVF with age regarding the atherosclerotic burden. Results The mean age of the 240 included subjects was 64.8 +/- 15.3 years, and 63% was male. Greater PF was associated with a higher degree of aortic atherosclerosis after adjusting for confounding variables (coefficient = 4.39, 95% CI = 0.83; 7.94, p = 0.02). Greater AVF was associated with a higher coronary stenosis index (coefficient = 1.49, 95% CI = 0.15; 2.83, p = 0.03) and a greater number of coronary plaques (coefficient = 0.71, 95% CI = 0.24; 1.19, p = 0.003). We did not find an association of PF or AVF with carotid or cerebral atherosclerotic burden. We found a significant interaction of AVF (coefficient = -0.08; 95% CI = -0.14; -0.02, p = 0.009) and PF (coefficient = -0.87, 95% CI = -1.70; -0.04, p = 0.04) with age regarding carotid artery atherosclerotic burden. Conclusions Greater AVF was associated with greater atherosclerotic burden and extent in coronary arteries, while greater PF correlated with a higher degree of atherosclerosis in the aorta.
- B Lymphocytes and Macrophages in the Perivascular Adipose Tissue Are Associated With Coronary Atherosclerosis: An Autopsy Study(2019) FARIAS-ITAO, Daniela Souza; PASQUALUCCI, Carlos Augusto; NISHIZAWA, Aline; SILVA, Luiz Fernando Ferraz da; CAMPOS, Fernanda Marinho; BITTENCOURT, Marcio Sommer; SILVA, Karen Cristina Souza da; LEITE, Renata Elaine Paraizo; GRINBERG, Lea Tenenholz; FERRETTI-REBUSTINI, Renata Eloah de Lucena; JACOB-FILHO, Wilson; SUEMOTO, Claudia KimieBackground Macrophages and T lymphocytes in the perivascular adipose tissue (PvAT) were previously linked to coronary artery disease. However, the role of these cells and B lymphocytes in the human PvAT adjacent to unstable atherosclerotic plaques has not been investigated. Moreover, previous studies were inconclusive on whether PvAT inflammation was restricted to the surroundings of the atheroma plaque. Methods and Results Coronary arteries were freshly dissected with the surrounding PvAT. Atherosclerotic plaques were classified according to the internationally accepted anatomopathological criteria. Immune cells in the PvAT were detected using immunohistochemistry and then quantified. We used linear and logistic regressions with robust standard errors, adjusted for possible confounding factors. In 246 atherosclerotic plaques (205 stable and 41 unstable plaques) from 82 participants (mean age=69.0 +/- 14.4 years; 50% men), the percentage of arterial obstruction was positively correlated with the densities of CD68(+) macrophages (P=0.003) and CD20(+) B lymphocytes (P=0.03) in the periplaque PvAT. The number of cells was greater in the periplaque PvAT than in the distal PvAT (macrophages, P<0.001; B lymphocytes, P=0.04). In addition, the density of macrophages in the periplaque PvAT was greater in the presence of unstable plaques (P=0.03) and was also greater near unstable plaques than in the distal PvAT (P=0.001). CD3(+) T lymphocytes were not associated with percentage of obstruction and stable/unstable plaque composition. Conclusions The density of CD20(+) B lymphocytes and CD68(+) macrophages in periplaque PvAT was increased with plaque size, and the CD68(+) macrophages were greater near unstable atherosclerotic plaques than near stable lesions. This inflammation was more intense in the periplaque PvAT than in the PvAT distal to the atherosclerotic plaques.
- Severe Dementia Predicts Weight Loss by the Time of Death(2021) CICILIATI, Aline Maria M.; ADRIAZOLA, Izabela Ono; FARIAS-ITAO, Daniela Souza; PASQUALUCCI, Carlos Augusto; LEITE, Renata Elaine Paraizo; NITRINI, Ricardo; GRINBERG, Lea T.; JACOB-FILHO, Wilson; SUEMOTO, Claudia KimieBackground: Body mass index (BMI) in midlife is associated with dementia. However, the association between BMI and late-life obesity is controversial. Few studies have investigated the association between BMI and cognitive performance near the time of death using data from autopsy examination. We aimed to investigate the association between BMI and dementia in deceased individuals who underwent a full-body autopsy examination. Methods: Weight and height were measured before the autopsy exam. Cognitive function before death was investigated using the Clinical Dementia Rating (CDR) scale. The cross-sectional association between BMI and dementia was investigated using linear regression models adjusted for sociodemographic and clinical variables. Results: We included 1,090 individuals (mean age 69.5 +/- 13.5 years old, 46% women). Most participants (56%) had a normal BMI (18.5-24.9 kg/m(2)), and the prevalence of dementia was 16%. Twenty-four percent of the sample had cancer, including 76 cases diagnosed only by the autopsy examination. Moderate and severe dementia were associated with lower BMI compared with participants with normal cognition in fully adjusted models (moderate: beta = -1.92, 95% CI = -3.77 to -0.06, p = 0.042; severe: beta = -2.91, 95% CI = -3.97 to -1.86, p < 0.001). Conclusion: BMI was associated with moderate and severe dementia in late life, but we did not find associations of BMI with less advanced dementia stages.
