Zika virus as a new pathogenic agent within the Toxoplasma gondii, Rubella virus, Cytomegalovirus, and Herpes simplex (TORCH) virus family: where do we stand?

Viral infections in low-income countries such as Brazil pose a significant challenge for medical authorities, with epidemics such as Zika virus infection having lasting effects. The increase in microcephaly among newborns has prompted investigations into the association between Zika virus and this congenital syndrome. The severity and prevalence of microcephaly led to the declaration of national and international emergencies. Extensive research has been conducted to understand the teratogenic effects of Zika virus, particularly its impact on neural progenitor cells in the fetal brain. Various pre- and postnatal imaging techniques, such as ultrasound, magnetic resonance imaging (MRI), and postnatal computed tomography (CT), have played crucial roles in diagnosing and monitoring malformations linked to congenital Zika virus infection in the central nervous system (CNS). These modalities can detect brain parenchymal abnormalities, calcifications, cerebral atrophy, and callosal anomalies. Additionally, three-dimensional ultrasound and fetal MRI provide detailed anatomical images, while CT can identify calcifications that are not easily detected by other methods. Despite advancements in imaging, there are still unanswered questions and ongoing challenges in comprehending the long-term effects and developmental impairments in children affected by Zika virus. Radiologists continue to play a crucial role in diagnosing and assisting in the management of these cases.

Clinical and epidemiological profiles from a case series of 26 Brazilian CADASIL patients.

BACKGROUND: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a genetic cause of ischemic stroke and the most common form of non-atherosclerotic stroke. Despite being the most prevalent vascular hereditary disease, clinical data regarding the Brazilian population are scarce. Considering that the Brazilian population has one of the most heterogeneous genetic constitutions in the world, knowledge about genetic and epidemiological profiles is mandatory. The present study aimed to elucidate the epidemiological and clinical features of CADASIL in Brazil. METHODS: We performed a case series study comprising 6 rehabilitation hospitals in Brazil and reported the clinical and epidemiological data from the medical records of patients admitted from 2002 to 2019 with genetic confirmation. RESULTS: We enrolled 26 (16 female) patients in whom mutations in exons 4 and 19 were the most common. The mean age at the onset of the disease was of 45 years. Ischemic stroke was the first cardinal symptom in 19 patients. Cognitive impairment, dementia, and psychiatric manifestations were detected in 17, 6, and 16 patients respectively. In total, 8 patients had recurrent migraines, with aura in 6 (75%) of them. White matter hyperintensities in the temporal lobe and the external capsule were found in 20 (91%) and 15 patients (68%) respectively. The median Fazekas score was of 2. Lacunar infarcts, microbleeds, and larger hemorrhages were observed in 18 (82%), 9, and 2 patients respectively. CONCLUSION: The present is the most extensive series of Brazilian CADASIL patients published to date, and we have reported the first case of microbleeds in the spinal cord of a CADASIL patient. Most of our clinical and epidemiological data are in accordance with European cohorts, except for microbleeds and hemorrhagic strokes, for which rates fall in between those of European and Asian cohorts.

MéTODOS: Apresentamos uma série de casos envolvendo 6 hospitais de reabilitação no Brasil, e relatamos dados clínicos e epidemiológicos de prontuários de pacientes admitidos entre 2002 e 2019 com confirmação genética. RESULTADOS: incluímos 26 pacientes (16 mulheres) em que as mutações nos éxons 4 e 19 eram as mais comuns. A idade média de início da doença foi de 45 anos. O AVC isquêmico foi o primeiro sintoma cardinal em 19 pacientes. Comprometimento cognitivo, demência e manifestações psiquiátricas foram detectados em 17, seis e 16 pacientes, respectivamente. Ao todo, 8 pacientes apresentavam enxaqueca, sendo com aura em 6 (75%) pacientes. Hiperintensidades de substância branca no polo temporal e na cápsula externa foram encontradas em 20 (91%) e 15 pacientes (68%), respectivamente. A pontuação mediana na escala de Fazekas foi de 2. Infartos lacunares, microssangramentos e macro-hemorragias foram observadas em 18 (82%), 9 (41%) e 2 (9%) pacientes, respectivamente. CONCLUSãO: O presente estudo representa a mais extensa série de pacientes brasileiros com CADASIL publicada até o momento, e relatamos o primeiro caso de micro-hemorragia na medula espinhal de um paciente com CADASIL. A maior parte dos nossos dados clínicos e epidemiológicos está de acordo com as coortes europeias, exceto para micro-hemorragias e macro-hemorragias, para as quais as taxas se enquadram entre as das coortes europeias e asiáticas.

Estimulação Transcraniana para Transtornos do Sono: uma revisão sistemática / Transcranial Stimulation in Sleep Disorders: a systematic review / Estimulación Transcraneal para los Trastornos del Sueño: una revisión sistemática

Os transtornos do sono podem ter várias consequências para a cognição, comportamento e vida social das pessoas. No entanto, a terapia utilizada para avaliar e intervir nesses transtornos ainda não está consolidada. Nesse contexto, o objetivo deste estudo foi verificar a aplicabilidade e eficácia da estimulação transcraniana (ETCA / ETCC / EMTr) nos transtornos do sono. Foi realizada uma busca sistemática de acordo com as diretrizes do PRISMA nas bases de dados Web of Science, PubMed, LILACS e SciELO. Inicialmente, foram encontrados 448 artigos, de acordo com os critérios de elegibilidade. O banco de dados de evidências de fisioterapia (PEDro) foi utilizado para avaliar a qualidade metodológica dos 11 artigos finais. Em geral, os resultados indicam que há tanto relatos favoráveis quanto desfavoráveis à eficácia do uso terapêutico das técnicas de estimulação transcraniana nos transtornos do sono e, portanto, ainda se configura como uma questão em aberto, dependendo de múltiplos fatores metodológicos e conceituais.

Sleep disorders can have several consequences on people's cognition, behavior and social life. However, the therapy used to assess and intervene in these disorders is not yet consolidated. In this context, the aim of this study was to verify the applicability and effectiveness of transcranial stimulation (tACS / tDCS / rTMS) in sleep disorders. A systematic search was performed according to PRISMA guidelines in the Web of Science, PubMed, LILACS, and SciELO databases. Initially, 448 articles were found, according to the eligibility criteria. The physiotherapy evidence database (PEDro) was used to assess the methodological quality of the 11 final articles. In general, the results indicate that there are both favorable and unfavorable reports on the effectiveness of the therapeutic use of transcranial stimulation techniques in sleep disorders and, therefore, it is still an open question, depending on multiple methodological and conceptual factors.

Effects of transcranial direct current stimulation on visuospatial attention in air traffic controllers.

Visuospatial attention is a cognitive skill essential to the performance of air traffic control activities. We evaluated the effect of an anodic session of transcranial low-intensity direct current stimulation (tDCS) right parietal associated with cognitive training of visuospatial attention of 21 air traffic controllers. Within-subject designs were used, with all volunteers undergoing two tDCS sessions; an experimental (2 mA anodic) and control (sham) performed concomitantly with the cognitive training (2-Back). Visuospatial performance was measured using the Attention Network Test for Interactions and Vigilance pre- and post-intervention. The results indicate that after an active parietal tDCS session, the ATCOs showed faster responses, but not more accurate, for visuospatial attention in its aspects of orientation and reorientation. This result was significant when comparing baseline and post-tests in the active tDCS group. Comparing the post-tests between the tDCS active and sham groups, it is possible to infer a trend of improvement in the results based on faster and more accurate responses, which suggests a possible refinement of the ATCO's attentional orientation. However, this population may eventually have reached a plateau in the performance of this skill. From the analysis of the results we arrive at the following hypotheses: (I) the increase in cortical excitability mediated by anodic tDCS frequently recorded may not be accompanied by improvements in behavioural measures; (II) the interaction between anodic tDCS with another event of increased excitability-execution of a cognitive task, may have hindered the occurrence of neuroplasticity; (III) the air traffic control activity may be associated with a high level of attention, which may have contributed to a ceiling effect for the development of this skill; (IV) online assessments may be more relevant to identify acute effects; (V) repeated sessions may be more efficient to find cumulative effects; (VI) the analysis of interactions between attentional networks can contribute to the study of visuospatial attention; (VII) tDCS protocols aimed at ATCO need to consider the specifics of this audience, such as circadian rhythm and sleep and fatigue conditions.

A retrospective cohort study of 238,000 COVID-19 hospitalizations and deaths in Brazil.

The coronavirus disease (COVID-19) pandemic has overwhelmed health care systems in many countries and bed availability has become a concern. In this context, the present study aimed to analyze the hospitalization and intensive care unit (ICU) times in patients diagnosed with COVID-19. The study covered 55,563 ICU admissions and 238,075 hospitalizations in Brazilian Health System units from February 22, 2020, to June 7, 2021. All the patients had a positive COVID-19 diagnosis. The symptoms analyzed included: fever, dyspnea, low oxygen saturation (SpO2 < 95%), cough, respiratory distress, fatigue, sore throat, diarrhea, vomiting, loss of taste, loss of smell, and abdominal pain. We performed Cox regression in two models (ICU and hospitalization times). Hazard ratios (HRs) and survival curves were calculated by age group. The average stay was 14.4 days for hospitalized patients and 12.4 days for ICU patients. For hospitalized cases, the highest hazard mean values, with a positive correlation, were for symptoms of dyspnea (HR = 1.249; 95% confidence interval [CI], 1.225-1.273) and low oxygen saturation (HR = 1.157; 95% CI 1.137-1.178). In the ICU, the highest hazard mean values were for respiratory discomfort (HR = 1.194; 95% CI 1.161-1.227) and abdominal pain (HR = 1.100; 95% CI 1.047-1.156). Survival decreased by an average of 2.27% per day for hospitalization and 3.27% per day for ICU stay. Survival by age group curves indicated that younger patients were more resistant to prolonged hospital stay than older patients. Hospitalization was also lower in younger patients. The mortality rate was higher in males than females. Symptoms related to the respiratory tract were associated with longer hospital stay. This is the first study carried out with a sample of 238,000 COVID-19 positive participants, covering the main symptoms and evaluating the hospitalization and ICU times.

Concern About Falling, Confidence in Balance, Quality of Life, and Depression Symptoms in Community-Dwelling Older Adults After a 24-week Dual-Task Training With Variable and Fixed Priority: A Randomized Controlled Trial.

OBJECTIVE: To evaluate the effect of a 24-week dual-task training with progression from variable to fixed priority on the concern about falling, confidence in balance, quality of life, and depression symptoms in community-dwelling older adults. METHODS: A total of 60 participants (60-80 y.o.) were randomly allocated into a dual-task training group with progression from variable to fixed priority (experimental group) or into a dual-task training group with variable priority (control group). RESULTS: No between-group difference was observed after the intervention. A significant time effect showed a reduction in concern about falling [mean difference (MD) = -2.91)] and depression symptoms (MD = -1.66), an increase in the physical function (MD = 7.86), overall mental health (MD = 5.82), perception of vitality, energy, and less fatigue (MD = 10.45), general perception of overall health (MD = 6.81), and their health compared to the last year (MD = 11.89). CONCLUSION: The experimental protocol was not superior to the control one. However, both protocols improved these outcomes.

A Brazilian multicentre study on the clinical and epidemiological profiles of 1116 patients with amyotrophic lateral sclerosis and its phenotypic variants.

Objective: We conducted a multicentre, cross-sectional analysis of Brazilian patients with amyotrophic lateral sclerosis (ALS) and its phenotypic variants. We describe and compare their clinical and epidemiological data. Methods: We collected data from 1,116 patients who visited seven rehabilitation hospitals in the SARAH network from 1 January 2009 to 20 March 2020. This representative sample of patients was from 308 cities in 25 states from the country's five regions. Results: The median age at onset was 55 years, and we found a significant linear correlation between the age at onset and the Municipal Human Development Index (MHDI) but not survival time. We found a four-year difference using a cutoff value of 0.750 (p < 0.001). There was a male predominance, with a 1.2:1 sex ratio. The median time from onset to diagnosis was 17.6 months, and the most common phenotypic presentations were spinal-onset and bulbar-onset ALS (62.7% and 14.7%, respectively). In total, 12.9% of the patients had familial ALS, likely due to the overrepresentation of ALS type 8 patients in our population. Conclusions: In general, our numbers are consistent with most international series and with those of other Brazilian cohorts. When patients were analyzed according to their MHDI a considerable delay in symptom onset was found, suggesting the possibility of an environmental effect on these patients. Brazil has a longer diagnostic delay which is similar to other less-developed countries. This is a substantial concern and should be a priority for health authorities and neurology societies.

Venolymphatic malformations: prenatal diagnosis using magnetic resonance imaging, perinatal outcomes and long-term follow-up.

BACKGROUND: Venolymphatic malformations are benign. Fetal MRI can more precisely demonstrate an infiltrative pattern of malformations than US. OBJECTIVE: To evaluate perinatal outcomes and long-term follow-up of fetal venolymphatic malformations treated in different medical facilities using fetal MRI. MATERIALS AND METHODS: This retrospective cohort study evaluated 20 pregnant women between 22 weeks and 37 weeks of gestation who were referred from different institutions. They presented with fetuses with various diagnoses of cystic masses on routine US. The cases were studied using MRI. We analyzed prenatal data, perinatal outcomes and long-term follow-up. RESULTS: We reviewed the MRI scans of 20 patients with venolymphatic malformation. Referral diagnosis was changed in 40% (8/20) of cases, with postnatal concordance of 100% (20/20). Moreover, 65% (13/20) presented with venolymphatic malformation in more than one body segment. The neck was affected in 70% (14/20) of fetuses, while the head and thorax were affected in 30% (6/20) and 45% (9/20), respectively. There were intrathoracic lesions in 35% (7/20), lesions in the abdomen in 30% (6/20), and lesions in the perineum and extremities in 10% (2/20) each. Tracheal displacement, neck deflection and anatomical displacement caused by tumoral compression were present in 15% (3/20) of cases. Moreover, 25% (5/20) of newborns required neonatal intensive care unit admission, and all presented with cervical or thoracic venolymphatic malformation. Furthermore, 50% (10/20) of cases presented with complete resolution after medical therapy. The intrathoracic and cervical residuals (35%, 7/20) were monitored and treated. CONCLUSION: MRI showed good correlation with postnatal examination of venolymphatic malformation, was useful in the differential diagnosis of fetal cysts on US, and presented a significant postnatal correlation with thoracic infiltration. The outcomes of prenatally diagnosed venolymphatic malformations are good despite the varying protocols among medical facilities.

Physalis angulata concentrated ethanolic extract suppresses nociception and inflammation by modulating cytokines and prostanoids pathways.

Physalins are seco-steroids with a variety of pharmacological activities already described. In this study the pharmacological properties of a standardized concentrated ethanolic extract from Physalis angulata (CEEPA), rich in physalins B, D, F and G, were studied in models of pain and inflammation in mice. Inflammatory mediators were measured by radioimmunoassay and Real-Time PCR in mice paws after the CFA stimuli. Systemic administration of CEEPA produced antinociceptive effect on the writhing test and formalin test. In the writhing test, physalins B, D, F and G showed that the antinociceptive effect of CEEPA is more potent than that of these purified compounds. In addition, CEEPA reduced the levels of TNF-α, IL-1ß, COX-2 and iNOS mRNA in the CFA-induced paw inflammation. Likewise, CEEPA decreased the TNF-α, IL-1ß and PGE2 paw levels. In conclusion, CEEPA induces antinociceptive and anti-inflammatory effects, with improved pharmacological potency relative to pure physalins, associated to modulation of cytokine and cyclooxygenase pathways.

Abstract The purpose of this research was to adapt the Structured Interview for Assessing Perceptual Anomalies (SIAPA) for use in Brazil as a self-report tool. A non-probabilistic sample of 854 undergraduate students was used, mostly men (51.4%) and aged between 16 and 65 years (M = 23.7, SD = 6.8). After the translation and semantic validation of SIAPA, the validity and precision parameters were tested by means of factor analysis, Cronbach's alpha coefficients, and Item Response Theory (IRT) analysis. The results confirmed the psychometric adequacy of the measure, pointing to a one-dimensional solution with high loads on the general factor and high accuracy (α = 0.88; Ω = 0.88). It is believed that the proposed objective was satisfied, so that at the end of the investigation there was a valid and reliable measure that can be used, both for screening and research, to understand and diagnose perceptual anomalies.

Prenatal diagnosis of cervical masses by magnetic resonance imaging and 3D virtual models: perinatal and long-term follow-up outcomes.

Objective: To assess perinatal and long-term follow-up outcomes of fetal cervical masses diagnosed by three-dimensional (3D) magnetic resonance imaging (MRI) and 3D virtual models.Methods: This retrospective cohort study evaluated 15 pregnant women (age, 21-38 years) at 29-40 weeks of singleton gestation, whose fetuses exhibited congenital oral and cervical masses. These women were referred to our facility because of suspected fetal malformations on routine obstetric ultrasound, and the cases were confirmed, excluded, or complemented by MRI. Demographic data and perinatal and long-term follow-up outcomes were assessed.Results: Cervical masses were predominant in females (3:2), and the most frequent diagnosis was lymphatic-venous malformation (71%). The masses were cystic in 53.3% of the cases and solid in 46.7%. The esophagus and trachea were displaced in 46.6% of the cases. Associated malformations were diagnosed in 13.3% of the cases. There was complete agreement between prenatal MRI and postnatal diagnoses. Among the newborns, 40% had complications and 46.6% were admitted to the neonatal intensive care unit. Two infants died from complications due to epignathus. Surgical resection was performed in 33.3% of the cases, including complete resection in 26.6%. Sclerotherapy was administered to 53.3% of the cases, with complete remission achieved in 50% of these cases.Conclusion: Cervical masses diagnosed in the prenatal period had good postnatal outcomes except for cases of epignathus, which were associated with high mortality. MRI demonstrated the relationship between cervical masses and adjacent organs and allowed 3D virtual reconstruction of the airways. There was complete agreement between the prenatal diagnosis of cervical masses on MRI and postnatal diagnosis. Surgical treatment was effective in most cases, and sclerotherapy was satisfactory in cases with intrathoracic components.

Association Between Neonatal Neuroimaging and Clinical Outcomes in Zika-Exposed Infants From Rio de Janeiro, Brazil.

Importance: Congenital Zika virus (ZIKV) infection may present with a spectrum of clinical and neuroradiographic findings. Objective: To determine whether neuroimaging findings for infants with a history of ZIKV exposure are associated with infant clinical outcomes and gestational age at antenatal ZIKV infection. Design, Setting, and Participants: This cohort study retrospectively reviewed neuroimaging results (computed tomography and/or magnetic resonance imaging scans) of 110 ZIKV-exposed infants from a maternity and children's hospital in Rio de Janeiro, Brazil, following the 2015 to 2016 ZIKV epidemic. Neuroimaging from March 1, 2016, to June 30, 2017, was evaluated to determine whether findings were associated with clinical outcomes and the timing of maternal ZIKV infection. Data were analyzed from July 1, 2017, to August 30, 2018. Exposures: Neuroimaging (computed tomography and/or magnetic resonance imaging) was performed on ZIKV-exposed infants after birth. Blood and/or urine specimens from mothers and infants were tested for ZIKV by polymerase chain reaction assay. Main Outcomes and Measures: Neuroimaging studies were evaluated for structural abnormalities and other forms of brain injury. Results: A total of 110 infants with a mean (SD) gestational age of 38.4 (2.1) weeks had neuroimaging and clinical outcome data reviewed. Of these, 71 (65%) had abnormal neuroimaging findings, with the majority (96%) classified as having severe ZIKV infection at birth. The most common neuroimaging abnormalities were structural abnormalities including brain calcifications, especially at the cortico-subcortical white matter junction, cortex malformations, ventriculomegaly, and reduced brain volumes, followed by brainstem hypoplasia, cerebellar hypoplasia, and corpus callosum abnormalities. Frequency of abnormal imaging was higher in infants with specific clinical findings as opposed to those without them; these findings included fetal brain disruption sequence (100% vs 35%), microcephaly (100% vs 30%), congenital contractures (100% vs 58%), ophthalmologic abnormalities (95% vs 44%), hearing abnormalities (100% vs 58%), and neurologic symptoms (94% vs 10%). Four of 39 infants (10%) without initial evidence of severe ZIKV infection and normal findings on neurologic evaluation at birth had abnormal neuroimaging findings. Neuroimaging abnormalities differed by trimester of maternal ZIKV infection, with 63% of infants born to mothers infected in the first trimester, 13% of infants born to mothers infected in the second trimester, and 1% of infants born to mothers infected in the third trimester exhibiting neuroimaging abnormalities. The odds of abnormal neuroimaging were 7.9 times greater for infants with first trimester ZIKV exposure compared with other trimesters combined (odds ratio, 7.9; 95% CI, 3.0-20.4; P < .001). Conclusions and Relevance: Neuroimaging abnormalities of computed tomography and/or magnetic resonance imaging scans were common in ZIKV-exposed infants. While neuroimaging abnormalities were seen in 10% of infants without clinically severe ZIKV, most occurred almost exclusively among those with clinically severe ZIKV, especially among those with a history of ZIKV exposure in the first trimester.

Grupo Intercultural: uma proposta para ressignificar os impactos da crise migratória na saúde mental de imigrantes e brasileiros em Roraima / Intercultural Group: a proposal to resignify the impacts of the migratory crisis on the mental health of immigrants and Brazilians at Roraima

Uma crise migratória como a que vem ocorrendo na Venezuela e afetando o Brasil causa diversos impactos tanto na população imigrante quanto na população de destino do fluxo migratório. Tais impactos impõem uma necessidade de adaptação e resiliência de pessoas que se veem obrigadas a compartilhar seu cotidiano nos mais diversos contextos. O presente trabalho objetiva relatar parte da experiência vivenciada na coordenação do Grupo Intercultural realizado em um Centro de Atenção Psicossocial de Boa Vista - RR. Os principais resultados observados entre os integrantes do grupo são: a valorização das ocupações e aspectos culturais dos povos e a percepção de que a crise pode trazer aprendizado e novos significados e formas de se comunicar com o outro. As oficinas terapêuticas são procedimentos fundamentais na saúde mental, pois são um instrumento essencial para estimular a reflexão, resignificação e a promoção dos vínculos interpessoais entre sujeitos que aparentemente viviam em contextos muito diferentes, mas que compartilham o sofrimento psíquico e a perda de sua autonomia e encontram na clínica intercultural a possibilidade de transformar sua interação com a sociedade. A equipe interdisciplinar em saúde mental tem muito a contribuir na atenção para pessoas que além de se encontrarem em processo de intenso sofrimento emocional, precisam lidar com transformações sociais e culturais céleres e permeadas de perdas significativas. É um processo recente, desafiador, mas com potencial de promoção de novas perspectivas para os profissionais de saúde e o público atendido.

A migratory crisis like the one that has been occurring in Venezuela and affecting Brazil causes several impacts both in the immigrant population and in the destination population of the migratory flow. These impacts impose a need for adaptation and resilience of people who are forced to share their daily lives in different contexts. The present work aims to report part of the experience lived in the coordination of the Intercultural Group carried out in a Psychosocial Care Center of Boa Vista. The main results observed among the members of the group are: the valorization of the occupations and cultural aspects of the people and the perception that the crisis can bring learning and new meanings and ways of communicating with the other. Therapeutic workshops are fundamental procedures in mental health, since they are an essential tool to stimulate reflection, reframing and promoting the interpersonal ties between individuals who apparently lived in very different contexts but who share the psychic suffering and the loss of their autonomy and find in the intercultural clinic the possibility of transforming their interaction with society. The interdisciplinary team in mental health has much to contribute in the attention to people who, besides being in the process of intense emotional suffering, have to deal with social and cultural transformations fast and permeated with significant losses. It is a recent, challenging process, but with potential to promote new perspectives for health professionals and the public served.

Capacidade funcional e fatores associados em idosos residentes em comunidade / Capacidad funcional y factores asociados en ancianos residentes en geriátricos / Functional capability and associated factors in the elderly living in the community

Resumo Objetivo Estimar o nível de capacidade funcional, as doenças autorreferidas e fatores associados entre idosos comunitários. Métodos Estudo quantitativo, descritivo, transversal, realizado com 159 idosos. Foram utilizados o questionário Brazil Old Age Schedule (BOAS), a escala de Lawton e Brody, o índice de Katz e um questionário de doença autorreferida. Resultados Na amostra de 159 participantes, 85 idosos tinham entre 60 e 70 anos, eram do sexo feminino, viúvos, divorciados ou nunca casados, sabiam ler e escrever, não trabalhavam e recebiam salário mínimo. Para as atividades básicas da vida diária, ter diabetes foi o fator mais importante, com 7.30 vezes a probabilidade de ser dependente. Para atividades instrumentais e avançadas da vida diária, não ser alfabetizado e sofrer acidente vascular cerebral (AVC), respectivamente, foram os fatores mais importantes. Conclusão A capacidade funcional foi associada à osteoporose e AVC, e teve correlação com doenças autorreferidas.

Abstract Objective Estimate the level of functional capacity, self-reported diseases and the associated factors between community-dwelling elderly people; Methods This was a quantitative, descriptive, cross-sectional study conducted with 159 elderly people. We used the Brazil Old Age Schedule, Lawton and Brody scale, Katz index and a self-reported disease questionnaire; Results In the sample of 159 participants, it was observed that of the elderly people were between 60 and 70 years old, female, widowed, divorced or never married, could read and write, did not work and received minimum wage. For basic activities of daily living, having diabetes was the most important factor, with seven point thirty times the likelihood of been dependent. For instrumental and advanced activities of daily living, not been literate and suffering from stroke, respectively, were the most important factors; Conclusion Functional capacity was associated with osteoporosis and stroke and was correlated with self-reported diseases.

Schizophrenia patients using atypical medication perform better in visual tasks than patients using typical medication.

Schizophrenia (SCZ) patients show deficits in many domains, including cognition and perception. However, results are often mixed. One reason for mixed results may be differences in medication. Very little is known about the role of medication in visual processing. Here, we investigated the effects of typical vs. atypical medication on contrast sensitivity (spatial frequencies ranging from 0.2 to 20 cycles per degree), vernier acuity, and visual backward masking. From a large pool of patients, we selected 50 patients (Study 1, conducted in Brazil) and 97 patients (Study 2, conducted in Georgia) taking either only typical or atypical medication. Patients with atypical medication performed significantly better than patients with typical medication for contrast sensitivity, vernier duration, and backward masking. As a secondary result, we found similar, but not significant, trends for the cognitive tasks (Stroop, Flanker, Trail-Making Test-B, Wisconsin Card Sorting Test and Continuous Performance Test) in the same patients. No correlations were found between demographics, psychopathology, chlorpromazine equivalents and visual processing. A conclusion of our study is that one needs to be careful comparing studies when medication is not comparable.
