Preparing for the COVID-19 Mental Health Crisis in Latin America – Using Early Evidence From Countries That Experienced COVID-19 First

Alberto Abad Juliana Almeida da Silva João Braga Priscila Medeiros Renato Leonardo de Freitas

The Covid-19 started in China and took over the world, becoming a pandemic. Especially in Latin America, the coronavirus arrived on the continent in mid-February 2020. The South American continent is going through a delicate political, economic and social moment, which is reflected in the fragility of our health systems and science and to reduce the rates of contagion and not overburden health services, including hospitals. Nevertheless, several studies are being carried out in Brazil and worldwide, with the objective sought to understand the characteristics, and even, the cure of people infected by the coronavirus. Therefore, we must consider science-based strategies to combat the pandemic and promote a health system that takes care of the population that needs it.

Scales for Subjective Distance in a Large Open Field from the Fractionation Method: Effects of Type of Judgment and Distance Range

Perceptual and Motor Skills (1982)

José Aparecido Da Silva

By means of the method of fractionation, scales for subjective distance were derived from five different types of judgment accomplished with two ranges of distance estimated in a large open field. It was found (a) that the scales for subjective distance are to a considerable extent influenced by ways of obtaining the judgments, (b) that the scales are relatively uninfluenced by range of distance, (c) that the exponents of the scales for egocentric distances are different from those for exocentric distances, (d) that the functions for egocentric distances are slightly decelerated but for exocentric distances slightly accelerated, and (e) that the average exponent for all subjects was 0.98.

The Primary Motor Cortex Stimulation Attenuates Cold Allodynia in a Chronic Peripheral Neuropathic Pain Condition in <i>Rattus norvegicus</i>

World Journal of Neuroscience (2019)

Priscila Medeiros Sylmara Esther Negrini-Ferrari Ana Carolina Medeiros Laís Ferreira Josie Resende Torres da Silva

Background: The primary motor cortex (M1) stimulation (MCS) is a useful tool for attenuation of the peripheral neuropathic pain in patients with pharmacologically refractory pain. Furthermore, that neurological procedure may also cause antinociception in rodents with neuropathic pain. Cold allodynia is a frequent clinical finding in patients with neuropathic pain, then, we evaluated if an adapted model of neuropathy induced by chronic constriction injury (CCI) of the ischiadicus nervus (sciatic nerve) produces cold allodynia in an animal model of chronic pain. In addition, we also investigated the effect of the electrical stimulation of the M1 on chronic neuropathic pain condition in laboratory animals. Methods: Male Wistar rats were used. An adapted model of peripheral mononeuropathy induced by CCI was carried out by placing a single loose ligature around the right sciatic nerve. The acetone test was used to evaluate the cold allodynia in CCI or Sham (without ligature) rats. The MCS (M1) was performed at low-frequency (20 μA, 100 Hz) during 15 s by deep brain stimulation (DBS-Thomas Recording device) 21 days after CCI or Sham procedures. The cold allodynia was measured before and immediately after the neurostimulation of M1 in the following time-window: 0, 15 and 30 min after MCS. Results: Cold allodynia threshold increased in animals with chronic neuropathic pain submitted to the acetone test 21 days after the CCI surgery. The M1-stimulation by DBS procedure decreased the cold allodynia immediately and until 30 min after M1-stimulation in rats with chronic neuropathic pain. Conclusion: The current proposal for a CCI model by a single loose ligature of the sciatic nerve can be employed as an experimental model of chronic neuropathic pain in rats submitted to peripheral nervous system injury. The M1-stimulation produced antinociception in rats with chronic neuropathic pain. Thus, we reinforced that the MCS decreases cold allodynia in laboratory animals submitted to persistent sciatic nerve constriction and can be a more reasonable procedure for the treatment of chronic intractable neuropathic pain.

Perceptual constancy in judgments of egocentric distance: prevailing binocular information

Arquivos Brasileiros de Oftalmologia (2003)

Elton H. Matsushima Igor O. Douchkin Nilton P. Ribeiro Filho José Aparecido Da Silva

Binocular cues were considered the prevailing information on specifying depth since the beginning of vision research. In the present study, two perceptual responses, the classical verbal report and a more recent method, open-loop walking, were used to assess the role of binocular information for egocentric distance perception. In two cue conditions environments, full- and reduced-cue, observers judged and walked egocentric distances of stimuli presented at eye-level, under binocular or monocular viewing. Results indicated perceptual constancy for open-loop walking and binocular responses, as well as poor performances under strong degradation on visual information (reduced-cue under monocular viewing), thus presenting evidence to support the fundamental role of binocular information on perception of egocentric distances. Besides that, visually directed actions could be adequate measures of perceived distance, with a better reliability than verbal report, since they were quite free of intrusion of inferential processes and perceptual tendencies. In addition, reduced head movements, side-to-side as well as back and forth deflexion movements, could have contributed to a near perfect coupling between binocular disparity information and open-loop walking responses.

Predictors of Depression and Anxiety Symptoms in Brazil during COVID-19

medRxiv (Cold Spring Harbor Laboratory) (2021)

Stephen X. Zhang Hao Huang Jizhen Li Mayra Antonelli-Ponti Scheila Farias de Paiva

Abstract The COVID-19 pandemic in Brazil is extremely severe, and Brazil has the third-highest number of cases in the world. The goal of the study is to identify the prevalence rates and several predictors of depression and anxiety in Brazil during the initial outbreak of COVID-19. We surveyed 482 adults in 23 Brazilian states online on 9–22 May 2020, and found 70.3% of the adults (N=339) had depressive symptoms and 67.2% (N=320) had anxiety symptoms. The results of multi-class logistic regression models revealed that females, younger adults and those with fewer children had a higher likelihood of depression and anxiety symptoms; adults who worked as employees were more likely to have anxiety symptoms than those who were self-employed or unemployed; adults who spent more time browsing COVID-19 information online were more likely to have depression and anxiety symptoms. Our results provide preliminary evidence and early warning for psychiatrists and healthcare organizations to better identify and focus on the more vulnerable sub-populations in Brazil during the ongoing COVID-19 pandemic.

Produzindo distâncias para evitar colisão contra um obstáculo fixo em ambiente rígido

Paidéia (Ribeirão Preto) (1999)

B. M. Sant’Anna Gomes Elton H. Matsushima Luiz Eduardo Oliveira Myriam dos Santos Nilton Ribeiro Filho

As pessoas, durante uma tarefa de caminhar sem visão para alvos previamente visualizados, usualmente realizam-na acuradamente, mesmo sem feedback visual. Quando falham, acidentes, como quedas, podem ocorrer. Estas falhas são geralmente associadas com erros humanos durante os processos de tomada de decisão, de ação ou de percepção. O presente trabalho foi desenvolvido para verificar se tais falhas, numa tarefa de evitar colisão, são associadas à orientação espacial e a tendências do observador. Planejamento: 4 grupos experimentais (Cena Completa, obstáculo e pontos de desvio; Imaginar, somente obstáculo; Sem Obstáculo; somente pontos de desvio; 10s de Atraso, obstáculo e pontos de desvio) x 3 distâncias do obstáculo (três, sete e 12 metros) x 2 distâncias de desvio (0,5 e 1,0 metro). Os observadores observaram a cena e, então, caminharam sem visão para os pontos de evitação. Os resultados mostraram uma acurácia no grupo Cena Completa, o que sugere uma pronunciada ação da informação visual na coordenação de comportamentos motores. A subestimativa encontrada nos outros indica que processos cognitivos, como a tendência do observador, podem conduzir a erros na ação. A acurácia na distância caminhada entre os pontos de desvio a 1,0m pode ser devida ao conforto da situação ou à forte ação da dimensão frontoparalela.

An Adapted Chronic Constriction Injury of the Sciatic Nerve Produces Sensory, Affective, and Cognitive Impairments: A Peripheral Mononeuropathy Model for the Study of Comorbid Neuropsychiatric Disorders Associated with Neuropathic Pain in Rats

Pain Medicine (2020)

Priscila Medeiros Ieda Regina dos Santos Ivair Matias Júnior Enza Palazzo José Aparecido Da Silva

Chronic constriction injury (CCI) is a model of neuropathic pain induced by four loose ligatures around the sciatic nerve. This work aimed to investigate the sensory, affective, cognitive, and motor changes induced by an adaptation of the CCI model by applying a single ligature around the sciatic nerve.Mechanical allodynia was measured from day 1 to day 28 postsurgery by the von Frey test. The beam walking test (BWT) was conducted weekly until 28 days after surgery. Anxiety- and depression-like behaviors, and cognitive performance were assessed through the open field (OF), forced swimming (FS), and novel object recognition (NOR) tests, respectively, 21 days after surgery.The two CCI models, both Bennett and Xie's model (four ligatures of the sciatic nerve) and a modification of it (one ligature), induced mechanical allodynia, increased immobility in the FS, and reduced recognition index in the NOR. The exploratory behavior and time spent in the central part of the arena decreased, while the defensive behavior increased in the OF. The animals subjected to the two CCI models showed motor alterations in the BWT; however, autotomy was observed only in the group with four ligatures and not in the group with a single ligature.Overall these results demonstrate that our adapted CCI model, using a single ligature around the sciatic nerve, induces sensory, affective, cognitive, and motor alterations comparable to the CCI model with four ligatures without generating autotomy. This adaptation to the CCI model may therefore represent an appropriate and more easily performed model for inducing neuropathic pain and study underlying mechanisms and effective treatments.

Estimation of the number of minimum salaries attributed to professions in function of their prestige

Fátima Aparecida Emm Faleiros Sousa José Aparecido Da Silva

The purpose of this study was to verify the relationship between professional prestige scaled through estimations and the professional prestige scaled through estimation of the number of minimum salaries attributed to professions in function of their prestige in society. Results showed: 1--the relationship between the estimation of magnitudes and the estimation of the number of minimum salaries attributed to the professions in function of their prestige is characterized by a function of potence with an exponent lower than 1,0,2--the orders of degrees of prestige of the professions resultant from different experiments involving different samples of subjects are highly concordant (W = 0.85; p < 0.001), considering the modality used as a number (estimation of magnitudes of minimum salaries).
