- 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.
- The action of phosphodiesterase-5 inhibitors on ?-amyloid pathology and cognition in experimental Alzheimer?s disease: A systematic review(2023) JUSTO, Alberto Fernando Oliveira; TOSCANO, Eliana Cristina de Brito; FARIAS-ITAO, Daniela Souza; SUEMOTO, Claudia KimieAlzheimer's disease (AD) is the most frequent cause of dementia worldwide. The etiology of AD is partially explained by the deposition of beta-amyloid in the brain. Despite extensive research on the pathogenesis of AD, the current treatments are ineffective. Here, we systematically reviewed studies that investigated whether phos-phodiesterase 5 inhibitors (PDE5i) are efficient in reducing the beta-amyloid load in hippocampi and improving cognitive decline in rodent models with beta-amyloid accumulation. We identified ten original studies, which used rodent models with beta-amyloid accumulation, were treated with PDE5i, and beta-amyloid was measured in the hippocampi. PDE5i was efficient in reducing the beta-amyloid levels, except for one study that exclusively used female rodents and the treatment did not affect beta-amyloid levels. Interestingly, PDE5i prevented cognitive decline in all studies. This study supports the potential therapeutic use of PDE5i for the reduction of the beta-amyloid load in hippocampi and cognitive decline. However, we highlight the importance of conducting additional experimental studies to evaluate the PDE5i-related molecular mechanisms involved in beta-amyloid removal in male and female animals.

- Potentially inappropriate medications and cognitive performance: cross-sectional results from the ELSA-Brasil study (nov 2022, 10.1007/s00228-023-03540-5)(2023) SANTOS, Adriana Nancy Medeiros dos; FARIAS-ITAO, Daniela Souza; BENSENOR, Isabela M.; GOULART, Alessandra C.; BRUNONI, Andre R.; VIANA, Maria Carmen; LOTUFO, Paulo A.; SUEMOTO, Claudia Kimie
- Social Isolation, Loneliness, and Cognitive Performance in Older Adults: Evidence From the ELSI-Brazil Study(2023) SOUZA, Jonas Gordilho; FARIAS-ITAO, Daniela Souza; ALIBERTI, Marlon J. R.; BERTOLA, Laiss; ANDRADE, Fabiola Bof de; LIMA-COSTA, Maria Fernanda; FERRI, Cleusa P.; SUEMOTO, Claudia K.Background: The association between social isolation and cognitive perfor-mance has been less investigated in low-to-middle-income countries (LMIC) and the presence of depression as a moderator on this association has not been examined. The authors examined the associations of social isolation and per-ceived loneliness with cognitive performance in the Brazilian Longitudinal Study of Aging. Methods: In this cross-sectional analysis, social isolation was evaluated by a composite score including marital status, social contact, and social support. The dependent variable was global cognitive performance, which considered memory, verbal fluency, and temporal orientation tests. Lin-ear and logistic regressions were adjusted for sociodemographic and clinical variables. The authors added interaction terms of depressive symptoms with social isolation and loneliness to examine whether depression, measured through the Center for Epidemiologic Studies-Depression Scale, modified these associations. Results: Among 6,986 participants (mean age = 62.1 9.2 years), higher levels of social connections were associated with better global cognitive performance (B = 0.02, 95%CI: 0.02; 0.04). Perceived loneliness was associated with worse cognition (B = -0.26, 95%CI = -0.34; -0.18). Interac-tions of depressive symptoms with social connections scores were found on memory z-score and with loneliness on global and memory z-scores, suggesting a weaker association between social isolation or loneliness and cognition among those with depressive symptoms. Conclusion: In a large sample from an LMIC, social isolation and loneliness were associated with worse cognitive performance. Surprisingly, depressive symptoms decrease the strength of these associations. Future longitudinal studies are important to assess the direction of the association between social isolation and cognitive performance. (Am J Geriatr Psychiatry 2023; 31:610-620)
- 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.
