A.- Similar Microglial Cell Densities across Brain Structures and Mammalian Species: Implications for Brain Tissue Function(2020) SANTOS, Sandra E. Dos; MEDEIROS, Marcelle; PORFIRIO, Jairo; TAVARES, William; PESSOA, Leila; GRINBERG, Lea; LEITE, Renata E. P.; FERRETTI-REBUSTINI, Renata E. L.; SUEMOTO, Claudia K.; JACOB FILHO, Wilson; NOCTOR, Stephen; SHERWOOD, Chet C.; KAAS, Jon H.; MANGER, Paul R.; HERCULANO-HOUZEL, SuzanaMicroglial cells play essential volume-related actions in the brain that contribute to the maturation and plasticity of neural circuits that ultimately shape behavior. Microglia can thus be expected to have similar cell sizes and even distribution both across brain structures and across species with different brain sizes. To test this hypothesis, we determined microglial cell densities (the inverse of cell size) using immunocytochemistry to Ibal in samples of free cell nuclei prepared with the isotropic fractionator from brain structures of 33 mammalian species belonging to males and females of five different clades. We found that microglial cells constitute similar to 7% of non-neuronal cells in different brain structures as well as in the whole brain of all mammalian species examined. Further, they vary little in cell density compared with neuronal cell densities within the cerebral cortex, across brain structures, across species within the same Glade, and across mammalian clades. As a consequence, we find that one microglial cell services as few as one and as many as 100 neurons in different brain regions and species, depending on the local neuronal density. We thus conclude that the addition of microglial cells to mammalian brains is governed by mechanisms that constrain the size of these cells and have remained conserved over 200 million years of mammalian evolution. We discuss the probable consequences of such constrained size for brain function in health and disease.
- Evaluation of the diaphragm muscle remodeling, inflammation, oxidative stress and vascularization in smokers: An autopsy study(2020) NUCCI, R.A.B.; MAIFRINO, L.B.M.; BUSSE, A.L.; SOUZA, R.R. De; PASQUALUCCI, C.A.; ANARUMA, C.A.; LEITE, R.E.P.; RODRIGUEZ, R.D.; SUEMOTO, C.K.; JACOB-FILHO, W.Background/Aims: Cigarette smoking is a key factor in systemic inflammation and oxidative stress, and it has also been associated with the loss of muscle strength and an elevated risk of pulmonary diseases. Thus, this study aimed to analyze the effects of cigarette smoking on the diaphragm muscle structure of postmortem samples. Methods: Immunohistochemical techniques were used for muscle remodeling (metalloproteinases 2 and 9), inflammation (cyclooxygenase-2), oxidative stress (8-hydroxy-2'-deoxyguanosine), and vascularization (vascular endothelial growth factor). Hematoxylin and eosin stain was used for histopathological analysis and Picrosirius stain was used to highlight the collagen fibers. Results: Cigarette smokers had an increase of diaphragm muscle remodeling, oxidative stress, inflammation, and vascularization compared to non-smokers. Conclusion: Diaphragm muscle structure may be negatively affected by cigarette smoking. © 2020 The Author(s).
- Persistent pain and cognitive decline in older adults: a systematic review and meta-analysis from longitudinal studies(2020) AGUIAR, Gabriella Pequeno Costa Gomes de; SARAIVA, Marcos Daniel; KHAZAAL, Eugenia Jatene Bou; ANDRADE, Daniel Ciampi de; JACOB-FILHO, Wilson; SUEMOTO, Claudia KimieBoth persistent pain and cognitive decline prevalence increase with advancing age and are associated with functional decline. However, the association of pain and cognitive decline has not been evaluated yet by a systematic assessment of longitudinal studies. We aimed to assess the association of persistent pain as a risk factor for cognitive decline in community older adults, using data from longitudinal studies in a systematic review and meta-analysis. Publications were identified using a systematic search on PubMed, EMBASE, and Cochrane Library databases from inception to June 2019. Because heterogeneity across studies was high, we used random-effects meta-analysis to calculate the pooled relative risk (RR) for the association between persistent pain and cognitive decline incidence. We investigated sources of heterogeneity among studies using meta-regression and stratified analyses. We included 10 prospective longitudinal studies with 57,495 participants with a mean age at the baseline ranging from 61.8 to 88.4 years and mean follow-up times ranging from 2.75 to 11.8 years. Persistent pain at baseline was not associated with the development of cognitive decline during the follow-up (pooled RR = 1.05, 95% confidence interval = 0.92-1.21). In sensitivity analyses, only length of follow-up time <= 4.5 years was associated with a higher risk of cognitive impairment (pooled RR = 1.19, 95% confidence interval = 1.10-1.28). Persistent pain was not associated with the incidence of cognitive decline.

- Chemical Composition of Quasi-ultrafine Particles and their Sources in Elderly Residences of Sao Paulo Megacity(2020) SEGALIN, Bruna; FORNARO, Adalgiza; KUMAR, Prashant; KLEMM, Otto; ANDRADE, Maria F.; TREZZA, Beatriz Maria; BUSSE, Alexandre; FILHO, Wilson J.; GONCALVES, Fabio L. T.Atmospheric quasi-ultrafine particles (qUFP; PM<0.25) can cause harmful effects to human health, mainly to elderly people. Although not always considered, these effects can be mostly due to its chemical composition. The scope of this work is (i) to quantify the abundance of ions and trace elements in qUFP in elderly residences, (ii) to identify the sources of these qUFP and (iii) to estimate the respiratory deposition doses (RDD) of qUFP and black carbon (rBC), which is an important component of qUFP, to various parts of the respiratory tract. In order to evaluate the qUFP chemical composition in elderly residences in the Metropolitan Area of Sao Paulo (MASP), we collected qUFP by using a Personal Cascade Impactor Sampler (PCIS). We analysed ions by chromatography and trace elements by Energy Dispersive X-Ray Fluorescence. We identified the sources of qUFP by applying Positive Matrix Factorization. We calculated the RDD through an equation, which use the tidal volume of lung, the typical breath frequency, the deposition fraction and the mass concentration of different size fractions of a PM. We collected 60 samples from 59 residences between May 2014 and July 2015. The major of ions concentrations in qUFP were found to be SO42- and NH4+, and the major trace elements were Si and Fe. Some residences have a high concentration of the toxic heavy metals Cu, Ni, Pb and Cr. We found six dominant sources of the indoor qUFP: vehicular emission (57%), secondary inorganic aerosol (21%), soil and construction (7%), wall painting (7%), cooking (5%) and industry (3%). The maximum RDD of qUFP and rBC are in the tracheobronchial part. Our results show that vehicular emissions dominate the indoor qUFP concentrations and uptake in elderly residences in the MASP.
- Delirium and Adverse Outcomes in Hospitalized Patients withCOVID-19(2020) GARCEZ, Flavia B.; ALIBERTI, Marlon J. R.; POCO, Paula C. E.; HIRATSUKA, Marcel; TAKAHASHI, Silvia de F.; COELHO, Venceslau A.; SALOTTO, Danute B.; V, Marlos L. Moreira; JACOB-FILHO, Wilson; AVELINO-SILVA, Thiago J.BACKGROUND Little is known about the association between acute mental changes and adverse outcomes in hospitalized adults with COVID-19. OBJECTIVES To investigate the occurrence of delirium in hospitalized patients with COVID-19 and explore its association with adverse outcomes. DESIGN Longitudinal observational study. SETTING Tertiary university hospital dedicated to the care of severe cases of COVID-19 in Sao Paulo, Brazil. PARTICIPANTS A total of 707 patients, aged 50 years or older, consecutively admitted to the hospital between March and May 2020. MEASUREMENTS We completed detailed reviews of electronic medical records to collect our data. We identified delirium occurrence using the Chart-Based Delirium Identification Instrument (CHART-DEL). Trained physicians with a background in geriatric medicine completed all CHART-DEL assessments. We complemented our baseline clinical information using telephone interviews with participants or their proxy. Our outcomes of interest were in-hospital death, length of stay, admission to intensive care, and ventilator utilization. We adjusted all multivariable analyses for age, sex, clinical history, vital signs, and relevant laboratory biomarkers (lymphocyte count, C-reactive protein, glomerular filtration rate, D-dimer, and albumin). RESULTS Overall, we identified delirium in 234 participants (33%). On admission, 86 (12%) were delirious. We observed 273 deaths (39%) in our sample, and in-hospital mortality reached 55% in patients who experienced delirium. Delirium was associated with in-hospital death, with an adjusted odds ratio of 1.75 (95% confidence interval = 1.15-2.66); the association held both in middle-aged and older adults. Delirium was also associated with increased length of stay, admission to intensive care, and ventilator utilization. CONCLUSION Delirium was independently associated with in-hospital death in adults aged 50 years and older with COVID-19. Despite the difficulties for patient care during the pandemic, clinicians should routinely monitor delirium when assessing severity and prognosis of COVID-19 patients.
