Quality of Life After Diagnosis of Neurally Mediated Reflex Syncope by Tilt Test

Abstract Background: Vasovagal syncope (VVS) results in impaired quality of life (QoL). The response during the head-up tilt test (HUTT) influences QoL and recurrence. Objectives: To analyze the influence of the type of HUTT response on QoL in patients with VVS and recurrence of events after the exam. Methods: The SF-36 and Impact of Syncope on Quality of Life (ISQL) questionnaires were applied over 12 months after the HUTT. Unpaired Student's t test was used for differences between 2 groups of quantitative data with normal distribution. The recurrence of syncope episodes was analyzed using a Kaplan-Meier curve, and the log-rank test was applied to compare the curves regarding responses to the HUTT. Statistical significance was set at p value < 0.05. Results: We analyzed 82 patients (43.7 years old), 69% with previous recurrence (2.8 prior episodes). Cardioinhibitory response occurred in 46 patients; vasodepressor response occurred in 36, and 85.4% of patients received non-pharmacological treatment after the HUTT. During clinical follow-up, 43.9% had recurrence, mainly young patients (35.7 years; p = 0.002). On the SF-36, the best score was in functional capacity in men (p = 0.04) and patients without prior trauma (p = 0.001). There were lower limitations due to pain in patients without prior trauma (p = 0.003) and patients without prodromes (p = 0.009). On the ISQL, there were better mean scores in men (p = 0.002) and in patients without prior trauma (p = 0.02). Patients with cardioinhibitory response had better SF-36 and ISQL scores (p < 0.001). There was greater VVS recurrence in the cardioinhibitory response group (log-rank p = 0.011; hazard ratio: 8.48; 95% confidence interval: 7.59 to 9.3) from the second to the fourth month, with stabilization in the eighth month after the HUTT, when compared to patients with vasodepressor response. Conclusion: The majority of patients with VVS reproduced during the HUTT under non-pharmacological treatment did not report worsening of QoL during clinical follow-up. Worse QoL was observed in non-young patients and in patients with vasodepressor response, and it was not influenced by recurrence after the HUTT.

Safety and feasibility of transcranial direct current stimulation in end-stage renal disease patients undergoing hemodialysis: an exploratory study / Segurança e viabilidade da estimulação transcraniana por corrente contínua em pacientes com doença renal em estágio terminal submetidos à hemodiálise: um estudo exploratório

Abstract Introduction: Patients with end-stage renal disease often face a challenging routine of hemodialysis, dietary restrictions, and multiple medications, which can affect their hemodynamic function. Home-based, safe, and nonpharmacological approaches such as transcranial direct current stimulation (tDCS) should be combined with conventional treatment. Objective: To assess the safety and feasibility of tDCS on blood pressure and heart rate in patients with end-stage renal disease undergoing hemodialysis. Method: This is a parallel, randomized, sham-controlled trial. Patients undergoing hemodialysis for more than three months were included. The patients received ten non-consecutive 2mA tDCS sessions on the primary motor cortex . Each session lasted 20 minutes. At baseline and after each of the ten sessions, blood pressure and heart rate of the patients were measured hourly for four hours. Results: Thirty patients were randomized to the active or sham group. The mean difference between the groups was calculated as the mean value of the sham group minus the mean value of the active group. Despite there were no statistical changes for all outcomes considering all 10 sessions, we found differences between groups for systolic -10.93 (-29.1;7.2), diastolic -3.63 (-12.4; 5.1), and mean blood pressure -6.0 (-16.3; 4.2) and hear rate 2.26 (-2.5; 7.1). No serious adverse events were found. The active group showed higher blood pressure values at all points, while heart rate was lower in the active group. Conclusion: tDCS is safe and feasible for patients with end-stage renal disease undergoing hemodialysis. Future studies should investigate whether tDCS could potentially induce a hypotensive protective effect during hemodialysis.

Resumo Introdução: Pacientes com doença renal em estágio terminal (DRET) geralmente enfrentam uma rotina desafiadora de hemodiálise, restrições alimentares e diversos medicamentos, podendo afetar sua função hemodinâmica. Abordagens domiciliares, seguras e não farmacológicas, como a estimulação transcraniana por corrente contínua (ETCC), devem ser combinadas com tratamento convencional. Objetivo: Avaliar segurança e viabilidade da ETCC na pressão arterial e frequência cardíaca em pacientes com DRET em hemodiálise. Método: Estudo paralelo, randomizado, controlado por placebo. Foram incluídos pacientes em hemodiálise por mais de três meses. Os pacientes receberam dez sessões não consecutivas de ETCC de 2mA no córtex motor primário. Cada sessão durou 20 minutos. No início do estudo e após cada uma das dez sessões, a pressão arterial e frequência cardíaca dos pacientes foram medidas a cada hora durante quatro horas. Resultados: Trinta pacientes foram randomizados para grupo ativo ou sham. A diferença média entre grupos foi calculada como valor médio do grupo sham menos valor médio do grupo ativo. Apesar de não haver alterações estatísticas para todos os desfechos considerando as 10 sessões, encontramos diferenças entre os grupos para pressão arterial sistólica -10,93 (-29,1; 7,2), diastólica -3,63 (-12,4; 5,1) e média -6,0 (-16,3; 4,2) e frequência cardíaca 2,26 (-2,5; 7,1). Não encontramos eventos adversos graves. O grupo ativo apresentou valores maiores de pressão arterial em todos os pontos, enquanto a frequência cardíaca foi menor no grupo ativo. Conclusão: ETCC é segura e viável para pacientes com DRET submetidos à hemodiálise. Estudos futuros devem investigar se a ETCC pode potencialmente induzir um efeito hipotensor protetor durante a hemodiálise.

How can we reduce maternal mortality due to preeclampsia? The 4P rule

Abstract In low and middle-income countries such as Brazil, most maternal deaths are related to hypertensive complications. Preeclampsia is the leading cause of maternal mortality and morbidity. Significant proportion is associated with the following factors: lack of identification of high-risk women, lack of adequate prevention, difficulty in maintaining a high-risk prenatal follow-up, delayed diagnosis, insecurity and low use of magnesium sulphate, delayed pregnancy interruption and lack of postpartum follow-up of these high-risk cases. Four major actions are proposed to minimize this alarming clinical picture and reduce the mortality rates due to preeclampsia, called the "4 P Rule" (Adequate Prevention - Vigilant Prenatal Care - Timely Delivery (Parturition) - Safe Postpartum). From this simple "rule" we can open a range of important processes and reminders that may help in the guidance of preeclampsia management.

Fisheries monitoring in Brazil: How can the 2030 agenda be met without fisheries statistics? / Monitoramento da pesca no Brasil: como cumprir a agenda 2030 sem estatísticas da pesca?

Every activity that involves exploitation of natural resources, such as fishing, needs to be organized and conducted based on information from monitoring programs to allow continuous evaluation. With the increasing fishing pressure in Brazil, the understanding of the importance of fisheries monitoring programs and how they can inform and assist in conservation decision-making remains limited. Based on the literature on fisheries and participatory conservation, we call attention to the need to generate information on the national fisheries sector in order to improve fisheries in the country. Given the context of the need to generate information on fishing stocks under exploitation, as well as to identify potential alternative fisheries and carry out various sectoral analyses in compliance with the 2030 Agenda for Sustainable Development, we present and discuss in the present paper the lack of a system of continuous fishing monitoring in Brazil and its effects on the fisheries sustainability in the country.

Toda atividade que atua envolvendo a exploração de recursos naturais, como a pesca, precisa ser organizada e conduzida com base nas informações dos programas de monitoramento para permitir uma avaliação contínua. Com o aumento da pressão pesqueira no Brasil, o entendimento da importância dos programas de monitoramento da pesca e como eles podem informar e auxiliar na tomada de decisões de conservação permanece limitado. Com base na literatura sobre pesca e conservação participativa, chamamos a atenção para a necessidade de gerar informações sobre o setor pesqueiro nacional para melhorar a pesca no país. Dado o contexto da necessidade de gerar informações sobre os estoques pesqueiros em exploração, bem como identificar potenciais alternativas de pesca e realizar diversas análises setoriais em conformidade com a Agenda 2030 para o Desenvolvimento Sustentável, é apresentada e discutida no presente trabalho a falta de um sistema de monitoramento contínuo da pesca no Brasil e seus efeitos na sustentabilidade da pesca no país.

Brazilian Black Women are at Higher Risk for COVID-19 Complications: An Analysis of REBRACO, a National Cohort / Mulheres negras brasileiras correm maior risco de complicações da COVID-19: uma análise do REBRACO, uma coorte nacional

Abstract Objective To evaluate the impact of the race (Black versus non-Black) on maternal and perinatal outcomes of pregnant women with COVID-19 in Brazil. Methods This is a subanalysis of REBRACO, a Brazilian multicenter cohort study designed to evaluate the impact of COVID-19 on pregnant women. From February2020 until February 2021, 15 maternity hospitals in Brazil collected data on women with respiratory symptoms. We selected all women with a positive test for COVID-19; then, we divided them into two groups: Black and non-Black women. Finally, we compared, between groups, sociodemographic, maternal, and perinatal outcomes. We obtained the frequency of events in each group and compared them using X2 test; p-values < 0.05 were considered significant. We also estimated the odds ratio (OR) and confidence intervals (CI). Results 729 symptomatic women were included in the study; of those, 285 were positive for COVID-19, 120 (42.1%) were Black, and 165 (57.9%) were non-Black. Black women had worse education (p = 0.037). The timing of access to the health system was similar between both groups, with 26.3% being included with seven or more days of symptoms. Severe acute respiratory syndrome (OR 2.22 CI 1.17-4.21), intensive care unit admission (OR 2.00 CI 1.07-3.74), and desaturation at admission (OR 3.72 CI 1.41-9.84) were more likely to occur among Black women. Maternal death was higher among Black women (7.8% vs. 2.6%, p = 0.048). Perinatal outcomes were similar between both groups. Conclusion Brazilian Black women were more likely to die due to the consequences of COVID-19.

Métodos Esta é uma subanálise da REBRACO, um estudo de coorte multicêntrico brasileiro desenhado para avaliar o impacto da COVID-19 em mulheres grávidas. De fevereiro de 2020 a fevereiro de 2021, 15 maternidades do Brasil coletaram dados de mulheres com sintomas respiratórios. Selecionamos todas as mulheres com teste positivo para COVID-19; em seguida, as dividimos em dois grupos: mulheres negras e não negras. Finalmente, comparamos, entre os grupos, os resultados sociodemográficos, maternos e perinatais. Obtivemos a frequência dos eventos em cada grupo e comparamos usando o teste X2; Valores de p <0,05 foram considerados significativos. Também estimamos o odds ratio (OR) e os intervalos de confiança (IC). Resultados 729 mulheres sintomáticas foram incluídas no estudo; desses, 285 foram positivos para COVID-19, 120 (42,1%) eram negros e 165 (57,9%) não eram negros. As mulheres negras apresentaram pior escolaridade (p = 0,037). O tempo de acesso ao sistema de saúde foi semelhante entre os dois grupos, com 26,3% incluídos com sete ou mais dias de sintomas. Síndrome respiratória aguda grave (OR 2,22 CI 1,17-4,21), admissão em unidade de terapia intensiva (OR 2,00 CI 1,07-3,74) e dessaturação na admissão (OR 3,72 CI 1,41-9,84) foram mais prováveis de ocorrer entre mulheres negras. A mortalidade materna foi maior entre as negras (7,8% vs. 2,6%, p = 0,048). Os resultados perinatais foram semelhantes entre os dois grupos. Conclusão Mulheres negras brasileiras tiveram maior probabilidade de morrer devido às consequências da COVID-19.

Diagnosis and Management of Preeclampsia: Suggested Guidance on the Use of Biomarkers / Diagnóstico e tratamento da pré-eclâmpsia: Sugestão para o uso adequado dos biomarcadores

Abstract Objective It is a challenge to consider preeclampsia (PE) diagnosis and management in low and middle-income settings, where it represents a major public health concern. The placenta is the underlying cause of disease, and the plasma concentrations of proangiogenic and antiangiogenic factors released by the placenta can reflect the risks of disease progression. Antiangiogenic proteins, such as soluble fms-like tyrosine kinase 1 (sFlt-1), and proangiogenic, like placental growth factors (PlGF), are directly and inversely correlated with the disease onset, respectively. Methods Narrative review on the use of biomarkers (sFlt-1 to PlGF ratio) with a suggested guidance protocol. Results Key considerations on the use of biomarkers: the sFlt-1/PlGF ratio is mainly relevant to rule out PE between 20 and 36 6/7 weeks in cases of suspected PE; however, it should not replace the routine exams for the diagnosis of PE. The sFlt-1/PlGF ratio should not be performed after confirmed PE diagnosis (only in research settings). In women with suspected PE, sFlt-1/PlGF ratio < 38 can rule out the diagnosis of PE for 1 week (VPN = 99.3) and up to 4 weeks (VPN= 94.3); sFlt-1/PlGF ratio > 38 does not confirm the diagnosis of PE; however, it can assist clinical management. In cases of severe hypertension and/or symptoms (imminent eclampsia), hospitalization is imperative, regardless of the result of the sFlt-1/PlGF ratio. Conclusion The use of biomarkers can help support clinical decisions on the management of suspected PE cases, especially to rule out PE diagnosis, thus avoiding unnecessary interventions, especially hospitalizations and elective prematurity

Resumo Objetivo um desafio considerar o diagnóstico e o tratamento da pré-eclâmpsia (PE) em locais de baixa e média renda, onde a doença representa um grande problema de saúde pública. A placenta é a causa subjacente da doença, e as concentrações plasmáticas de fatores pró-angiogênicos e antiangiogênicos liberados pela placenta podem refletir os riscos de progressão da doença. Proteínas antiangiogênicas, como a tirosina quinase fms solúvel tipo 1 (sFlt-1), e pró-angiogênicas, como o fator de crescimento placentário (PlGF), estão direta e inversamente correlacionados com o início da doença, respectivamente. Métodos Revisão narrativa sobre o uso de biomarcadores (razão sFlt-1/PlGF) com sugestão de protocolo de orientação para uso clínico. Resultados Principais considerações sobre o uso de biomarcadores: a razão sFlt-1/PlGF é principalmente relevante para descartar PE entre 20 e 36 6/7 semanas em casos de suspeita de PE; entretanto, não deve substituir os exames de rotina para o diagnóstico de PE. A relação sFlt-1/PlGF não deve ser realizada após a confirmação do diagnóstico de PE (apenas em ambientes de pesquisa). Em mulheres com suspeita de PE, a razão sFlt-1/PlGF < 38 pode descartar o diagnóstico de PE por 1 semana (VPN = 99,3) e até 4 semanas (VPN = 94,3); A relação sFlt-1/PlGF > 38 pode auxiliar no manejo clínico. Em casos de hipertensão grave e/ou sintomas (eclâmpsia iminente), a hospitalização é imprescindível, independentemente do resultado da relação sFlt-1/PlGF. Conclusão O uso de biomarcadores pode auxiliar na tomada de decisões clínicas no manejo de casos suspeitos de PE, principalmente para afastar o diagnóstico da doença, evitando intervenções desnecessárias, tais como internações e prematuridade iatrogênica.

Does anodal transcranial direct current stimulation over left motor cortex show body side pain-related difference in fibromyalgia? / A estimulação transcraniana por corrente contínua anódica sobre o córtex motor esquerdo apresenta diferença na dor entre os hemicorpos na fibromialgia?

ABSTRACT BACKGROUND AND OBJECTIVES: Fibromyalgia (FM) is a chronic widespread musculoskeletal pain resulting in central sensitization of nociceptive signaling. Transcranial direct current stimulation (tDCS) over the left motor cortex (M1) is a non-invasive neuromodulation technique indicated for a broad range of chronic pain disorders, including FM. Studies suggest that left and right M1 (contralateral and ipsilateral hemisphere of tDCS stimulation) are modulated. But it is necessary to clarify the differences in clinical pain perception comparing the right and left side of the body. This study aimed to evaluate the pain-related difference between right-left side of the body after five sessions of anodal tDCS in women with FM. METHODS: A double-blinded, parallel, randomized, sham-controlled trial with 30 women with FM was performed. Five sessions of anodal C3 and cathodal supraorbital (Fp2) tDCS were conducted (2 mA for 20 min). Pain, impact of FM and anxiety were evaluated. No statistically significant three-way interaction between time, stimulation type and body side were found. RESULTS: Active-tDCS showed significant improvement in pain, but impact of FM and anxiety did not show significant improvement. CONCLUSION: Five sessions of anodal tDCS over the left M1 improves pain in women with FM, however there was no difference between right-left body sides.

RESUMO JUSTIFICATIVA E OBJETIVOS: A fibromialgia (FM) é uma dor musculoesquelética crônica generalizada que resulta na sensibilização central da sinalização nociceptiva. A estimulação transcraniana de corrente contínua (eTCC) sobre o córtex motor esquerdo (M1) é uma técnica de neuromodulação não invasiva indicada para uma ampla gama de distúrbios de dor crônica, incluindo a FM. Estudos sugerem a modulação do M1 esquerdo e direito (hemisfério contralateral e ipsilateral da eTCC). Mas é necessário esclarecer as diferenças na percepção clínica da dor comparando os lados direito e esquerdo do corpo. Este estudo teve como objetivo avaliar a diferença relacionada à dor entre o lado direito e esquerdo do corpo após cinco sessões de eTCC anodal em mulheres com FM. MÉTODOS: Foi realizado um estudo duplo-cego, paralelo, randomizado e controlado por sham com 30 mulheres com FM. Foram realizadas cinco sessões de eTCC anodais C3 e supraorbitais catodais (Fp2) (2 mA por 20 min). Foram avaliados a dor, o impacto da FM e a ansiedade. Não foi encontrada nenhuma interação de três vias estatisticamente significativa entre tempo, tipo de estimulação e lado do corpo. RESULTADOS: A eTCC-Ativa mostrou uma melhora significativa na dor, mas o impacto da FM e da ansiedade não mostrou uma melhora significativa. CONCLUSÃO: Cinco sessões de eTCC anodal sobre o M1 esquerdo melhoram a dor nas mulheres com FM, entretanto não houve diferença entre os lados direito e esquerdo do corpo.

Analysis of a Brazilian cross-cultural adaptation of the FACE-Q SFAOS in facial harmonization in dentistry

Abstract: The FACE-Q SFAOS is an instrument developed for esthetic facial procedures and has been validated in patients undergoing rhinoplasty. It consists of ten items that assess the current perception of facial appearance regarding symmetry, harmony, proportion, freshness or vitality, and self-perception of appearance; these items are perhaps important to guide demands in orofacial harmonization (OFH). We aimed to validate the FACE-Q SFAOS scale among professionals working with OFH and verify its acceptance for use in clinical practice. Altogether, 25 OFH specialists were included to evaluate the FACE-Q SFAOS scale and the new technology acceptability model (TAM). Internal validity was measured using Cronbach's α coefficient. Both scales were associated with clinical experience and perceived usefulness using Spearman's correlation and Fisher's exact or chi-square tests (SPSS 20.0, p < 0.05). The FACE-Q SFAOS (α = 0.927) and TAM (α = 0.941) scales demonstrated good internal validity, and most professionals demonstrated good acceptance (TAM >70 = 64%). The mean FACE-Q SFAOS and TAM scores were 64.00±17.03 and 74.60±20.66, respectively. Practitioners with more than two years of experience (p=0.032) who believed the scale was useful for lip filler evaluation (p = 0.017) demonstrated greater acceptance. The number of indications on the scale was directly correlated with higher levels of acceptance (p = 0.002, r = 0.594). Thus, the FACE-Q SFAOS scale has good reproducibility and acceptance among OFH specialists; however, acceptability was shown to be dependent on perceived usability.

Legal, normativo e responsivo: frames no debate sobre a reforma dos Tribunais de Contas brasileiros / Legal, normativo y responsivo: frames en el debate sobre la reforma de los tribunales de cuentas brasileños / Legal, normative, and responsive frames in the debate about the reform of Brazilian Courts of Accounts

Resumo Esta pesquisa teve como objetivo descrever os frames (enquadramentos) associados ao processo de mobilização em torno do debate sobre a reforma dos Tribunais de Contas brasileiros (TCs) no período de 2000 a 2017. Por meio de legitimacy accounts (assertivas de legitimidade) de atores legais e não legais foram identificados três frames: legal, associado à regulação, ressignificação e conformidade legal dos TCs; normativo, relacionado à transição da gestão política à competência técnica dos TCs e; responsivo, ligado à visibilidade social dos TCs. Os dados analisados consideraram discursos parlamentares, audiências públicas, debates, notícias e entrevistas com representantes de segmentos específicos como corporações profissionais, mídia, academia e sociedade civil organizada. Os achados lançam luz sobre a natureza processual da legitimidade em organizações institucionalizadas, como é o caso dos TCs, e destacam: a emergência das corporações profissionais enquanto entes mobilizadores das três esferas de segmentação; o surgimento de tônica cerimonialista em aspectos fomentadores do comportamento interoganizacional e; o aumento progressivo da responsividade ligada ao campo como decorrência do ingresso de segmentos específicos da sociedade no debate. Os resultados aprofundam a natureza político-discursiva da mudança institucional.

Resumen Esta investigación describe los marcos (frames) asociados al proceso de movilización en torno al debate sobre la reforma de los tribunales de cuentas (TC) brasileños en el período de 2000 a 2017. A través de los relatos de legitimidad de los actores legales y no legales, se identificaron tres marcos: legal, asociado a la regulación, resignificación y cumplimiento legal de los TC; normativo, asociado a la transición de la gestión política a la competencia técnica de los TC; y responsivo, asociado a la visibilidad social de los TC. Para el análisis de los datos se consideraron los discursos parlamentarios, audiencias públicas, debates, noticias y entrevistas con representantes de segmentos específicos, como corporaciones profesionales, medios de comunicación, academia y sociedad civil organizada. Las conclusiones arrojan luz sobre la dimensión procesal de la legitimidad en los tribunales y ponen de relieve: el surgimiento de las corporaciones profesionales como movilizadoras de las tres esferas de la segmentación; la aparición de un tono ceremonial en aspectos que fomentan el comportamiento interoganizacional y el aumento progresivo de la capacidad de respuesta vinculada al campo como resultado de la entrada de segmentos específicos de la sociedad en el debate. Los resultados profundizan el carácter político-discursivo del cambio institucional.

Abstract: This research describes the frames associated with the mobilization process around the debate about the reform of Brazilian Courts of Accounts (TCs) from 2000 to 2017. Through legitimacy accounts of legal and non-legal actors, three frames were identified: legal, associated with regulation, reframing, and legal compliance of TCs; normative, associated with the transition from political management to the technical competence of TCs and; responsive, associated with the social visibility of TCs. The data consisted of parliamentary speeches, public hearings, debates, news broadcasts, and interviews with representatives of specific segments such as professional corporations, media, academia, and organized civil society. The findings shed light on the procedural dimension of legitimacy in Justice organizations and highlight the emergence of professional corporations as mobilizing entities in the three spheres of segmentation; the emergence of a ceremonial tonic in aspects that promote inter-organizational behavior, and; the progressive increase in responsiveness linked to the field as a result of the entry of specific segments of society in the debate. The results deepen the political-discursive nature of institutional change.

Pre-eclampsia: Universal screening or universal prevention for low and middle-income settings? / Pré-eclâmpsia: Rastreamento universal ou prevenção universal para países de baixa e média-renda?

Abstract Pre-eclampsia (PE) is a severe disorder that affects up to 8% of all pregnancies and represents an important cause of maternal and perinatal morbidity and mortality. The screening of the disease is a subject of studies, but the complexity and uncertainties regarding its etiology make this objective a difficult task. In addition, the costs related to screening protocols, the heterogeneity of the most affected populations and the lack of highly effective prevention methods reduce the potential of current available algorithms for screening. Thus, the National Specialized Commission of Hypertension in Pregnancy of the Brazilian Association of Gynecology and Obstetrics Federation (Febrasgo, in the Portuguese acronym) (NSC Hypertension in Pregnancy of the Febrasgo) considers that there are no screening algorithms to be implemented in the country to date and advocates that Aspirin and calcium should be widely used.

Resumo A Pré-eclâmpsia (PE) é uma doença grave que acomete ~ 8% das gestações e representa importante causa de morbimortalidade, tanto materna quanto perinatal. O rastreamento da doença émotivo de estudos, porém a complexidade e as incertezas quanto a sua etiologia tornam esse objetivo bastante difícil. Além disso, os custos relacionados com o rastreamento, a heterogeneidade das populações mais afetadas e ainda a falta de métodos de prevenção de grande eficácia reduzem o potencial dos algoritmos de rastreamento. Assim, a Comissão Nacional Especializada sobre Hipertensão na Gravidez da Federação Brasileira das Associações de Ginecologia e Obstetrícia (CNE Hipertensão na Gravidez da FEBRASGO) considera que não há algoritmos de rastreamento que possam ser aplicados no país nesse momento e defende a utilização dos métodos de prevenção como ácido acetilsalicílico e cálcio de maneira ampla.

Transcranial direct current stimulation as a strategy to manage COVID-19 pain and fatigue

SUMMARY The novel coronavirus disease (COVID-19) has infected millions of people worldwide and generated many sequels in the survivors, such as muscular pain and fatigue. These symptoms have been treated through pharmacological approaches; however, infected people keep presenting physical limitations. Besides, the COVID-19 damage to the central nervous system has also been related to the presence of some physical impairment, so strategies that focus on diverse brain areas should be encouraged. Transcranial Direct Current Stimulation (tDCS) is a non-pharmacological tool that could be associated with pharmacological treatments to improve the central nervous system function and decrease the exacerbation of the immune system response. tDCS targeting pain and fatigue-related areas could provide an increase in neuroplasticity and enhancements in physical functions. Moreover, it can be used in infirmaries and clinical centers to treat COVID-19 patients.

Coronavirus disease 2019 and human reproduction: a changing perspective

Since the outbreak of severe acute respiratory coronavirus 2 (SARS-CoV-2), the coronavirus disease 2019 has had a wide range of effects on human health. This paper summarizes the data related to the effects of the SARS-CoV-2 infection on human reproduction. Both the male and female reproductive tract express high levels of receptors and proteins needed for viral cell entry. There is presently no evidence that gametes are affected by the infection. Male fertility may be temporarily reduced due to inflammatory responses following infection. The endometrium is highly susceptible to SARS-CoV-2 cell entry; however, it remains unclear whether this could alter receptivity and embryo implantation. Menstrual cycle changes were reported in women who experienced severe infection; however, they tended to be reversible. For couples undergoing assisted reproduction treatment, the pandemic led to a significant psychological burden, with changes in lifestyle that could directly affect the success of the treatment. Human reproduction societies recommend screening all patients prior to cycle initiation and avoiding treatment of women with severe comorbidities until the pandemic is under control. Finally, for pregnant women, it is expected that the infection is more severe in women in the third trimester and in those with comorbidities. Those who are symptomatic for SARS-CoV-2 are more likely to have increased rates of prematurity and intrapartum fetal distress than those who are asymptomatic. Vertical transmission cannot be completely ruled out, but neonatal infection rates are low. Vaccination appears to be safe and is indicated for use in pregnant and lactating women because the benefits outweigh the risks.

Comment on The importance of physical exercise during the coronavirus (COVID-19) pandemic

SUMMARY Currently, many people have been infected by the Coronavirus disease (COVID-19) and presented cardiorespiratory symptoms caused mainly by the host immune system response and respiratory tract inflammation. So far, there is no effective treatment to fight off COVID-19 and, despite many daily speculations about new treatments and vaccines, in this article, we discuss the effectiveness of a cheap and scientific proven technique to treat and prevent several diseases. Many studies have shown the benefits of physical exercise in individuals who have practiced it routinely. This approach is a great strategy to improve people's cardiorespiratory capacity, inflammation system, and immune response. Due to the quarantine period, the practice of physical exercise at home can also be used to fight off COVID-19 and must be inserted into people's routines.

RESUMO Atualmente, muitas pessoas ainda têm sido infectadas pelo Coronavírus (COVID-19) e apresentado sintomas cardiorrespiratórios gerados principalmente pela resposta do sistema imune do hospedeiro e inflamação do trato respiratório. Até agora, não existe nenhum tratamento efetivo para combater o COVID-19 e apesar de muitas especulações diárias sobre novos tratamentos e vacinas, neste artigo, nós discutimos sobre a efetividade de uma técnica barata e cientificamente comprovada para tratar e prevenir diversas doenças. Muitos estudos têm demonstrado os benefícios do exercício físico em indivíduos que tem praticado de forma rotineira. Esta abordagem é uma excelente estratégia para melhorar a capacidade cardiorrespiratória, sistema inflamatório e resposta imune. Devido ao período de quarentena, a prática de exercício físico em casa pode também ser usada para combater o COVID-19 e deve ser inserida na rotina das pessoas.

The accuracy of the Montenegro skin test for leishmaniasis in PCR-negative patients

Abstract INTRODUCTION: As highly specific molecular biology-based techniques may not be sensitive enough for the diagnosis of American tegumentary leishmaniasis (ATL), clinicians frequently rely on immunological tests before treatment initiation. Hence, the correct combination of diagnostic tests is imperative for ATL diagnosis. We aimed to evaluate the accuracy of the Montenegro (Leishmanin) skin test (MST) in polymerase chain reaction (PCR)-negative patients to accurately detect ATL. METHODS: Patients with a clinical picture compatible with ATL were divided into ATL (confirmed by lesion smear, culture indirect immunofluorescence, and/or histopathology) and no-ATL (diseases that can mimic leishmaniasis) groups. Conventional PCR for the minicircle kDNA of Leishmania was performed, and the MST was carried out for PCR-negative patients. RESULTS: Ninety-nine patients were included in this study, including 79 diagnosed with ATL (6 with mucocutaneous leishmaniasis) and 20 without ATL (no-ATL group). The MST showed a high sensitivity of 90.0% (95% confidence interval [CI] = 69.90-97.21) in PCR-negative patients that was 10% higher than the sensitivity reported in PCR-positive population (79.66%; 95% CI = 67.73-87.96). CONCLUSIONS: One of the most important reasons for PCR negativity among patients with active ATL is the presence of a strong cellular immunological response, especially in chronic and mucocutaneous leishmaniasis. This reinforces the considerable utility of the tests that detect cellular responses against Leishmania antigens such as the MST in PCR-negative patients when the performance in screening situations is questionable.

COVID-19 and social isolation: the consequences of not exercising for older adults' health

Abstract COVID-19 pandemic has required social isolation to prevent the virus from spreading. Initially, the elderly were the most affected by the novel coronavirus. However, the virus spread out worldwide, affecting all age groups. The elderly are commonly affected by several chronic diseases, and as a consequence of social isolation caused by the COVID-19 pandemic, the community-based exercise programs, which usually provide health and well-being to the elderly, have stopped their activities to avoid the virus to spread out; so, the elderly kept taking medicines but stopped exercising, which must impair their health and increase demand from the public health system. In this sense, the physical education professional is essential to providing safe approaches to the elderly who are not able to enroll in community-based exercise programs but need to exercise to improve their health. This article aims to discuss the consequences of not exercising in older adults' health during the social isolation caused by the COVID-19 pandemic; still, we intend to present adjunct strategies to allow the elderly to exercise even socially isolated.
