ABSTRACT BACKGROUND: Precisely determining the aspects related to an instrument's validity and reliability measures allows for greater assurance of the quality of the results. OBJECTIVES: To analyze the psychometric properties of The Providers Survey in the Brazilian context of mental health services. DESIGN AND SETTING: The instrument validation study was conducted in Montes Claros, Minas Gerais, Brazil. METHODS: The validation study was conducted using the Consensus-based Standards for the Selection of Health Measurement Instruments checklist to analyze its validity and reliability. RESULTS: A committee of expert judges performed content validation after which the Content Validity Index was calculated. Construct validation took place through Exploratory Factor Analysis using the Kaiser-Meyer-Olkin Test criterion and Bartlett's Sphericity Test. Reliability was verified using test-retest reliability. The significance level adopted for the statistical tests was 5% (P < 0.05). The final instrument comprised 54 questions. The Content Validity Index was 97%. Exploratory Factor Analysis identified a Kaiser-Meyer-Olkin index of 0.901 and Bartlett's Sphericity Test with P < 0.001. We obtained a Cronbach's alpha coefficient of 0.95 and an intraclass correlation coefficient of 0.849. CONCLUSIONS: The Providers Survey, translated and adapted into Portuguese, was named the Work Assessment Instrument for the Recovery of Mental Health. It presented adequate psychometric properties for evaluating work-related practices for the recovery of psychosocial care network users.

ABSTRACT Objective: The COVID-19 pandemic has profoundly disrupted health care worldwide. We aimed to evaluate the impact of the first COVID-19 wave on the treatment of our patients with acromegaly. Subjects and methods: A standard questionnaire was systematically applied to all patients and included questions on general health status, whether all laboratory workup had been done, common signs and symptoms of acromegaly, treatment adherence, and previous COVID-19 symptoms and diagnosis. Results: We attempted to contact 136 patients with acromegaly at regular follow-up at our institution and contacted 101 of them successfully. In all, 37% of the patients reported symptoms of acromegaly, which was more common among women. A total of 27 patients were lost to follow-up (including 19 who interrupted treatment during the pandemic) mainly for fear of becoming infected by the SARS-CoV-2. Of these, 24 resumed follow-up after our contact. Conclusions: The current COVID-19 pandemic has strongly impacted the follow-up of patients with acromegaly. Telemedicine can be an important tool to maintain regular treatment in the current or future pandemics.

Abstract Peripheral facial paralysis (PFP) has been shown to be a neurological manifestation of COVID-19. The current study presents two cases of PFP after COVID-19, along with a rapid review of known cases in the literature. Both case reports were conducted following CARE guidelines. We also performed a systematic review of PFP cases temporally related to COVID-19 using PubMed, Embase, and Cochrane Library databases on August 30, 2021, using a rapid review methodology. The two patients experienced PFP 102 and 110 days after COVID-19 symptom onset. SARS-CoV-2 RNA was detected in nasal samples through reverse-transcription real-time polymerase chain reaction (RT-qPCR) testing. Anosmia was the only other neurological manifestation. PFP was treated with steroids in both cases, with complete subsequent recovery. In the rapid review, we identified 764 articles and included 43 studies. From those, 128 patients with PFP were analyzed, of whom 42.1% (54/128) were male, 39.06% (50/128) female, and in 23 cases the gender was not reported. The age range was 18 to 59 (54.68%). The median time between COVID-19 and PFP was three days (ranging from the first symptom of COVID-19 to 40 days after the acute phase of infection). Late PFP associated with COVID-19 presents mild symptoms and improves with time, with no identified predictors. Late PFP should be added to the spectrum of neurological manifestations associated with the long-term effects of SARS-CoV-2 infection as a post COVID-19 condition.

RESUMO Os canabinoides compreendem os endocanabinoides, fitocanabinoides e os canabinoides sintéticos e desempenham ações no sistema nervoso central e periférico. Uma quantidade enorme de publicações tem sido lançada nos últimos anos, embora a cannabis seja conhecida por milênios. Os Departamentos Científicos da Academia Brasileira de Neurologia descreveram as evidências do uso médico em suas áreas. A literatura está em constantes mudanças e possíveis novas evidências podem surgir nos próximos dias ou meses. A prescrição dessas substâncias deve ser discutida com os pacientes e suas famílias, com conhecimento sobre eventos adversos e sua eficácia.

ABSTRACT Cannabinoids comprehend endocannabinoids, phytocannabinoids, and synthetic cannabinoids, with actions both in the central and peripherical nervous systems. A considerable amount of publications have been made in recent years, although cannabis has been known for over a thousand years. Scientific Departments from the Brazilian Academy of Neurology described evidence for medical use in their areas. Literature is constantly changing, and possible new evidence can emerge in the next days or months. Prescription of these substances must be discussed with patients and their families, with knowledge about adverse events and their efficacy.

Resumo O presente estudo objetiva discutir o conhecimento e as práticas dos profissionais da Atenção Primária à Saúde sobre os modos de interação disciplinar. Trata-se de um estudo descritivo, de abordagem qualitativa, com a proposta metodológica da Cartografia, em que foram realizados quatro grupos focais com a participação de 33 profissionais, dentre eles médicos, enfermeiros e cirurgiões-dentistas, de equipes de Saúde da Família (eSF). A partir de um mapeamento cartográfico, foi possível perceber que o contexto do trabalho das eSF pode ser representado pelo plano de forma, que é afetado pelo plano de forças, gerando inter-relações. A partir destas, emergem os modos de interação disciplinar como linha de escape, produzindo novos agenciamentos, caracterizados pelas perspectivas e proposições elencadas pelos profissionais. Por meio desse mapeamento, ficou evidente a importância dos modos de interação disciplinar na prática das eSF como resposta, principalmente, à micropolítica do trabalho vivo em saúde, com centralidade nas tecnologias leves.

Abstract The present study aims to discuss the knowledge and practices of Primary Health Care professionals about the modes of disciplinary interaction. It is a descriptive study, with qualitative approach following the methodological proposal of cartography, in which we ran four focus groups with the participation of 33 professionals, among them doctors, nurses and dental surgeons who are part of Family Health teams (FHt). With a cartographic mapping, it was possible to see that the work context of the FHt can be represented by the plan of form, which is affected by the plan of forces, generating interrelationships. From this, the modes of disciplinary interaction emerge as a line of escape, producing new assemblages characterized by the perspectives and proposals listed by the professionals. Through this mapping, the importance of the modes of disciplinary interaction in the FHt practice was evident, mainly as a response to the micropolitics of living labor in health with a focus on lightweight technologies.

OBJECTIVES: We designed a cohort study to describe characteristics and outcomes of patients with coronavirus disease (COVID-19) admitted to the intensive care unit (ICU) in the largest public hospital in Sao Paulo, Brazil, as Latin America becomes the epicenter of the pandemic. METHODS: This is the protocol for a study being conducted at an academic hospital in Brazil with 300 adult ICU beds dedicated to COVID-19 patients. We will include adult patients admitted to the ICU with suspected or confirmed COVID-19 during the study period. The main outcome is ICU survival at 28 days. Data will be collected prospectively and retrospectively by trained investigators from the hospital’s electronic medical records, using an electronic data capture tool. We will collect data on demographics, comorbidities, severity of disease, and laboratorial test results at admission. Information on the need for advanced life support and ventilator parameters will be collected during ICU stay. Patients will be followed up for 28 days in the ICU and 60 days in the hospital. We will plot Kaplan-Meier curves to estimate ICU and hospital survival and perform survival analysis using the Cox proportional hazards model to identify the main risk factors for mortality. ClinicalTrials.gov: NCT04378582. RESULTS: We expect to include a large sample of patients with COVID-19 admitted to the ICU and to be able to provide data on admission characteristics, use of advanced life support, ICU survival at 28 days, and hospital survival at 60 days. CONCLUSIONS: This study will provide epidemiological data about critically ill patients with COVID-19 in Brazil, which could inform health policy and resource allocation in low- and middle-income countries.

RESUMO: A aplicação de herbicidas dessecantes na cultura do feijoeiro é fundamental na produção de sementes de qualidade porque antecipa a época de colheita, o que possibilita a obtenção de sementes no período de maturação fisiológica, quando se encontram com máximo acúmulo de matéria seca, elevados níveis de vigor e alta porcentagem de germinação. Todavia, são escassas as informações acerca da época ideal de aplicação desses produtos na obtenção de sementes de feijão de alta qualidade fisiológica. Por essa razão, objetivou-se avaliar a qualidade fisiológica de sementes de feijão após aplicações de herbicidas dessecantes em diferentes épocas na pré-colheita. O delineamento experimental utilizado foi o de blocos casualizados dispostos em esquema fatorial 2x3+1, com quatro repetições. A aplicação dos herbicidas dessecantes paraquat (400g ha-1) e paraquat + diuron (200+400g ha-1) foi realizada em três estádios fenológicos (R8, R8/R9 e R9), mais uma testemunha (sem aplicação do herbicida). Avaliou-se a produtividade (Kg ha-1), a massa de mil sementes (g), a germinação (%) e o vigor das sementes por meio dos testes de envelhecimento acelerado, condutividade elétrica e comprimento da raiz primária. A aplicação da molécula de paraquat no estádio R8 e da mistura paraquat + diuron no estágio R8/R9 reduziu a viabilidade e o vigor das sementes de feijão, além disso comprometeu a produtividade. Aplicações dos herbicidas paraquat nos estádios R8/R9 e R9 ou da mistura (paraquat + diuron) no estádio R9 preservaram a qualidade fisiológica das sementes, sem, entretanto, afetar a produtividade.

ABSTRACT: The application of desiccant herbicides in the bean crop is fundamental in the production of quality seeds, since it anticipates the harvesting season, which makes it possible to obtain seeds in the period of physiological maturation, when they are reported with maximum accumulation of dry matter, high vigor levels and germination percentage. However, there is little information about the ideal application time of these products to obtain beans of high physiological quality. Therefore, the objective of this study was to evaluate the physiological quality of bean seeds after application of desiccant herbicides at different times in preharvest. The experimental design was a randomized complete block design in a 2x3+1 factorial scheme, with four replications. Desiccant herbicides paraquat (400g ha-1) and paraquat + diuron (200 + 400g ha-1) were applied in three phenological stages (R8, R8/R9 and R9), plus one control (without herbicide application). Yield (Kg ha-1), mass of one thousand seeds (g), germination (%) and seed vigor were evaluated through tests of accelerated aging, electrical conductivity and primary root length. Application of paraquat molecule at the R8 stage and the paraquat + diuron mixture at the R8/R9 stage reduced the viability and vigor of the bean seeds, and compromised yield. Applications of the paraquat herbicide at the R8/R9 and R9 stages or of the mixture (paraquat + diuron) at the R9 stage preserved the physiological quality of the seeds without;however, affecting yield.

Abstract Micro-morphological changes precede the appearance of visible damage after herbicide application and are essential in providing data for the safe recommendation in chemical management of weeds. Therefore, the aim of this research was to verify the anatomical changes of leaf tissue caused by application of herbicides in cassava (Manihot esculenta Crantz.cv. IAC-12). A greenhouse experiment was conducted with post-emergence herbicides treatments as follows: nicossulfuron (60 g a.i ha-1), fluazifop (250 g a.i ha-1), fomesafem (250 g a.i ha-1), metribuzin (480 g a.i ha-1), oxyfluorfen (720 g a.i ha-1) and the mixture fluazifop + fomesafen (200 + 250 g a.i ha-1), and an untreated control, respectively. The results obtained have allowed to affirm the cassava plants (cultivar IAC-12), exhibited changes in leaf anatomy in response to herbicide application even on cassava leaves without no visual toxicity symptoms. The products caused alterations both in tissue thickness as in tissue proportion in the leaf blade. For the fluazifop, a eudicotyledonous selective herbicide, changes were observed in tissue thickness and proportion of leaf blade, even without any visual toxicity detected. Cassava plants (IAC-12), showed structural changes in leaf anatomy in response to application of herbicides. The leaf anatomy of cassava cv. IAC-12, can be used to indicate the herbicide effect on cassava (Manihot esculenta Crantz.cv. IAC-12) plants.

Resumo Mudanças micro-morfológica precede o aparecimento de danos visíveis após a aplicação do herbicida e são essenciais no fornecimento de dados para a recomendação segura no manejo químico de ervas daninhas. Assim, o objetivo deste trabalho visou verificar as alterações anatômicas do tecido foliar causada pela aplicação de herbicidas em mandioca (Manihot esculenta Crantz.cv. IAC-12). Um experimento foi conduzido em ambiente protegido com os seguintes herbicidas aplicados em pós-emergência na cultura da mandioca: nicossulfuron (60 g i.a ha-1), fluazifop (250 g i.a ha-1), fomesafem (250 g i.a ha-1), metribuzin (480 g i.a ha-1), oxyfluorfen (720 g i.a ha-1), a mistura fluazifop + fomesafen (200 + 250 g ha-1), e um tratamento sem aplicação de herbicidas. Os resultados obtidos permitem afirmar que as plantas de mandioca (cultivar IAC-12) apresentaram mudanças na anatomia foliar, em resposta à aplicação do herbicida até mesmo em folhas sem nenhum sintoma visual de intoxicação. Os produtos causaram alterações tanto na espessura do tecido como na proporção de tecidos na lâmina de folha. Para o fluazifop, um herbicida seletivo para espécies eudicotiledôneas foram observadas alterações na espessura do tecido e na proporção de lâminas foliares, mesmo quando não foram detectadas sintoma visual de intoxicação nas folhas. As plantas de mandioca (IAC-12) apresentaram mudanças estruturais na anatomia foliar em resposta à aplicação de herbicidas. A anatomia da folha da mandioca (Manihot esculenta Crantz.cv. IAC-12) é um parâmetro para indicar o efeito de herbicidas em relação as avaliações visuais.

ABSTRACT This study evaluated the jack bean (Canavalia ensiformis) as a potential remediator of sulfentrazone in the soil. The experiment was conducted under field conditions in a complete randomised block design. The treatments consisted of soils with and without herbicide application as well as the absence and presence of C. ensiformis cultivation associated with incorporation into the soil or the removal of shoots of C. ensiformis. Sorghum was planted as a bioindicator to evaluate the remediation efficiency of jack bean. Sulfentrazone application in areas without C. ensiformis cultivation decreased plants stands, productivity, and height of sorghum compared to treatments where C. ensiformis was cultivated. Sorghum cultivated in succession to C. ensiformis in areas contaminated with sulfentrazone resulted in dry matter production, plants numbers, productivity, and height of sorghum equivalent to uncontaminated areas. The results of this research indicate that the use of jack bean for the bioremediation of sulfentrazone treated soils would provide greater security in the planting of susceptible species in areas where this herbicide has been applied. The cultivation of C. ensiformis in contaminated areas may reduce the risk of environmental impacts caused by sulfentrazone.

O objetivo deste trabalho foi avaliar a qualidade fisiológica de sementes de berinjela osmocondicionadas submetidas à secagem. Utilizaram-se sementes de berinjela, cultivar Embu, condicionadas em solução aerada de KNO3 (-0,8 MPa), a 25ºC, por 48 horas. As sementes foram submetidas aos seguintes procedimentos: redução do teor de água inicial (r), choque térmico (CT) e secagem lenta (SL) ou rápida (SR) por 48 horas. As combinações desses procedimentos constituíram os tratamentos: sementes condicionadas e sem secagem, SL, SR, CTSL, CTSR, rSL, rSR, rCTSL e rCTSR, além da testemunha (sementes sem condicionamento). As sementes condicionadas e as secas lentamente expressaram maior percentagem de germinação. Não houve diferença entre os tratamentos quanto à percentagem de emergência de plântulas. A testemunha levou mais tempo para alcançar a máxima emergência do que os demais tratamentos. As sementes submetidas ao choque térmico apresentaram maiores valores de condutividade elétrica do que as que não passaram por esse tratamento. A qualidade fisiológica das sementes de berinjela obtida com o condicionamento é mantida após a secagem. A secagem de sementes de berinjela condicionadas deve ser realizada preferencialmente de forma lenta, com ou sem redução do teor de água inicial.

The objective of this work was to evaluate the physiological quality of osmoprimed eggplant seeds subjected to drying. Eggplant seeds of the cultivar Embu, primed in aerated KNO3 (-0.8 MPa) solution, at 25ºC, for 48 hours, were used. The seeds were subjected to the following procedures: reduction of initial moisture content (r), heat shock (CT), and slow (SL) or fast drying (SR) for 48 hours. The combination of these procedures formed the treatments: primed seeds without drying, SL, SR, CTSL, CTSR, rSL, rSR, rCTSL, and rCTSR, besides a control (seeds without priming). Seeds primed and those dried slowly expressed higher germination percentage. No difference was observed among treatments for seedling emergence percentage. The control took more time to express maximum emergence than the other treatments. Seeds subjected to heat shock presented higher values of electrical conductivity than those that did not undergo this treatment. The physiological quality of eggplant seeds gained with priming is maintained after drying. The drying of primed eggplant seeds should be preferably performed slowly, with or without reduction of initial moisture content.

O objetivo do presente estudo foi analisar o efeito da manipulação de duas diferentes ordens de exercícios com pesos, utilizando o sistema tri-set sobre o desempenho motor em exercícios para o peitoral. Dez homens (25,6 ± 5,7 anos; 77,0 ± 5,8 kg; 172,9 ± 5,0 cm; 25,7 ± 1,4 kg/m²) com experiência em treinamento com pesos foram submetidos a duas sessões experimentais, nas quais os sujeitos realizaram duas sequências de exercícios para o peitoral: SEQA (supino horizontal, supino inclinado e voador) e SEQB (voador, supino Inclinado e supino horizontal). A carga utilizada permitiu a realização de 8 a 12 repetições (80% de 1-RM) em cada exercício. Verificou-se um maior número de repetições na SEQB (29 ± 2 reps vs. 26 ± 3 reps; P < 0,001) e maior sobrecarga total (carga utilizada x repetições executadas = 1.942 ± 172 kg vs. 1.728 ± 234 kg; P < 0,001). Os resultados sugerem que, no sistema de tri-set, o maior número de repetições e o maior volume de treinamento é alcançado quando o exercício monoarticular é inserido antes dos exercícios multiarticulares.

The aim of this study was to analyze the effect of the manipulation of two different exercise orders using the tri-set system on the motor performance in exercises for the chest. Ten male (25.6 ± 5.7 years, 77.0 ± 5.8 kg, 172.9 ± 5.0 cm, 25.7 ± 1.4 kg/m²) with experience in resistance training underwent two experimental sessions, in which the subjects performed two sequences of exercises for the chest: SEQA (bench press, incline bench press, and peck deck) and SEQB (peck deck, incline bench press, and bench press). The load used allowed 8 to 12 repetitions (80% of 1RM) in each exercise. A higher number of repetitions (29 ± 2 reps vs. 26 ± 3 reps, P < 0.001) and a greater total overload (resistance used x repetitions performed = 1,942 ± 172 kg vs. 1,728 ± 234 kg, P < 0.001) were observed in SEQB. The results suggest that in the tri-set system the higher number of repetitions and a greater training volume occur when the single-joint exercise is included before multiple-joint exercises.

OBJETIVO: Descrever a frequência de prescrição de quelantes de fósforo (QF) e calcitriol em pacientes sob hemodiálise (HD) crônica em Salvador, Brasil, e avaliar se o tratamento está de acordo com recomendações do Kidney Disease Outcomes Quality Initiative (K/DOQI). MÉTODOS: Corte transversal de dados da linha de base do Estudo Prospectivo do Prognóstico de Pacientes Tratados Cronicamente por Hemodiálise (PROHEMO). Foi realizada descrição da frequência de prescrição de QF e calcitriol conforme as concentrações de indicadores laboratoriais do metabolismo mineral, comparando com recomendações do K/DOQI. RESULTADOS: Sevelamer isoladamente (i.e., não combinado com outro QF) foi prescrito para 45,4% dos pacientes, carbonato de cálcio (CaCO3) isoladamente para 26,5%, sevelamer combinado com CaCO3 para 2,1% e acetato de cálcio para 5,2%. Prescrição de QF foi observada para 53% dos pacientes com fósforo <3,5 mg/dL e 40% com fósforo <3,0 mg/dL. Em desacordo com K/DOQI, prescrição de calcitriol foi detectada para 19% dos pacientes com PTH<150 pg/mL e ausência da prescrição para aproximadamente 35,4% com PTH>300 pg/dL combinado com fósforo menor ou igual a 5,5 mg/dL, cálcio menor ou igual a 9,5 mg/dL e produto cálcio e fósforo (CaxP)<55 mg2/dL2. Neste último grupo, 38% tiveram prescrição de sevelamer sem outro QF. CONCLUSÃO: Os resultados mostram um elevado percentual de prescrição de sevelamer em pacientes em HD de manutenção em uma cidade brasileira, apesar do alto custo deste medicamento e ausência de contraindicação para QF à base de cálcio. Os resultados em pacientes com PTH<150 pg/mL e com PTH>300 pg/mL combinado com determinadas concentrações de cálcio, fósforo e CaxP indicam também a necessidade de avaliar as práticas de uso de QF e calcitriol.

OBJECTIVE: To describe the frequency of prescription of phosphate binders (PB) and calcitriol for patients on chronic hemodialysis in Salvador, Brazil, and to assess whether treatment is in agreement with recommendations of the Kidney Disease Outcomes Quality Initiative (K/DOQI). METHODS: Cross section of baseline data of the PROHEMO study. The frequency of prescription of PB and calcitriol according to laboratory indicators of mineral metabolism was compared with K/DOQI recommendations. RESULTS: Sevelamer alone (i.e., not combined with other PB) was prescribed for 45.4% of patients, calcium carbonate (CaCO3) alone for 26.5%, sevelamer combined with CaCO3 for 2.1% and calcium acetate for 5.2%. Prescription of PB was noted in 53% of the patients with phosphorus <3.5 mg/dL and 40% with phosphorus <3.0 mg/dL. In disagreement with K/DOQI, prescription of calcitriol was found in 19% of patients with PTH<150 pg/mL and prescription was absent for approximately 35.4% with PTH>300 pg/dL combined with phosphorus equal or less than 5.5 mg/dL, calcium equal or less than 9.5 mg/dL and calcium x phosphorus product (CaxP)<55 mg2/dL2. For this latter group 38% had a prescription of sevelamer without other phosphate binders. CONCLUSION: Results show a large percentage of prescriptions of sevelamer among patients on maintenance hemodialysis in a Brazilian city, despite the high cost of the medication and absence of contraindications for PB with calcium salts. Results in patients with PTH<150 pg/mL and with PTH>300 pg/mL combined with certain concentrations of calcium, phosphate and CaxP also indicate the need to evaluate practices for use of phosphate binders and calcitriol.
