RESUMO Objetivo: Descrever as práticas de ressuscitação volêmica em unidades de terapia intensiva brasileiras e compará-las com as de outros países participantes do estudo Fluid-TRIPS. Métodos: Este foi um estudo observacional transversal, prospectivo e internacional, de uma amostra de conveniência de unidades de terapia intensiva de 27 países (inclusive o Brasil), com utilização da base de dados Fluid-TRIPS compilada em 2014. Descrevemos os padrões de ressuscitação volêmica utilizados no Brasil em comparação com os de outros países e identificamos os fatores associados com a escolha dos fluidos. Resultados: No dia do estudo, foram incluídos 3.214 pacientes do Brasil e 3.493 pacientes de outros países, dos quais, respectivamente, 16,1% e 26,8% (p < 0,001) receberam fluidos. A principal indicação para ressuscitação volêmica foi comprometimento da perfusão e/ou baixo débito cardíaco (Brasil 71,7% versus outros países 56,4%; p < 0,001). No Brasil, a percentagem de pacientes que receberam soluções cristaloides foi mais elevada (97,7% versus 76,8%; p < 0,001), e solução de cloreto de sódio a 0,9% foi o cristaloide mais comumente utilizado (62,5% versus 27,1%; p < 0,001). A análise multivariada sugeriu que os níveis de albumina se associaram com o uso tanto de cristaloides quanto de coloides, enquanto o tipo de prescritor dos fluidos se associou apenas com o uso de cristaloides. Conclusão: Nossos resultados sugerem que cristaloides são usados mais frequentemente do que coloides para ressuscitação no Brasil, e essa discrepância, em termos de frequências, é mais elevada do que em outros países. A solução de cloreto de sódio 0,9% foi o cristaloide mais frequentemente prescrito. Os níveis de albumina sérica e o tipo de prescritor de fluidos foram os fatores associados com a escolha de cristaloides ou coloides para a prescrição de fluidos.
Abstract Objective: To describe fluid resuscitation practices in Brazilian intensive care units and to compare them with those of other countries participating in the Fluid-TRIPS. Methods: This was a prospective, international, cross-sectional, observational study in a convenience sample of intensive care units in 27 countries (including Brazil) using the Fluid-TRIPS database compiled in 2014. We described the patterns of fluid resuscitation use in Brazil compared with those in other countries and identified the factors associated with fluid choice. Results: On the study day, 3,214 patients in Brazil and 3,493 patients in other countries were included, of whom 16.1% and 26.8% (p < 0.001) received fluids, respectively. The main indication for fluid resuscitation was impaired perfusion and/or low cardiac output (Brazil: 71.7% versus other countries: 56.4%, p < 0.001). In Brazil, the percentage of patients receiving crystalloid solutions was higher (97.7% versus 76.8%, p < 0.001), and 0.9% sodium chloride was the most commonly used crystalloid (62.5% versus 27.1%, p < 0.001). The multivariable analysis suggested that the albumin levels were associated with the use of both crystalloids and colloids, whereas the type of fluid prescriber was associated with crystalloid use only. Conclusion: Our results suggest that crystalloids are more frequently used than colloids for fluid resuscitation in Brazil, and this discrepancy in frequencies is higher than that in other countries. Sodium chloride (0.9%) was the crystalloid most commonly prescribed. Serum albumin levels and the type of fluid prescriber were the factors associated with the choice of crystalloids or colloids for fluid resuscitation.

Abstract Spondyloarthritis (SpA) is a group of chronic inflammatory systemic diseases characterized by axial and/or peripheral joints inflammation, as well as extra-articular manifestations. Over some decades, nonsteroidal anti-inflammatory drugs (NSAIDs) have been the basis for the pharmacological treatment of patients with axial spondyloarthritis (axSpA). However, the emergence of the immunobiologic agents brought up the discussion about the role of NSAIDs in the management of these patients. The objective of this guideline is to provide recommendations for the use of NSAIDs for the treatment of axSpA. A panel of experts from the Brazilian Society of Rheumatology conducted a systematic review and meta-analysis of randomized clinical trials for 15 predefined questions. The Grading of Recommendations, Assessment, Development and Evaluation methodology to assess the quality of evidence and formulate recommendations were used, and at least 70% agreement of the voting panel was needed. Fourteen recommendations for the use of NSAIDs in the treatment of patients with axSpA were elaborated. The purpose of these recommendations is to support clinicians’ decision making, without taking out his/her autonomy when prescribing for an individual patient.

Abstract Spondyloarthritis is a group of chronic inflammatory systemic diseases characterized by axial and/or peripheral joints inflammation, as well as extra-articular manifestations. The classification axial spondyloarthritis is adopted when the spine and/or the sacroiliac joints are predominantly involved. This version of recommendations replaces the previous guidelines published in May 2013. A systematic literature review was performed, and two hundred thirty-seven studies were selected and used to formulate 29 recommendations answering 15 clinical questions, which were divided into four sections: diagnosis, non-pharmacological therapy, conventional drug therapy and biological therapy. For each recommendation the level of evidence supporting (highest available), the strength grade according to Oxford, and the degree of expert agreement (inter-rater reliability) is informed. These guidelines bring evidence-based information on clinical management of axial SpA patients, including, diagnosis, treatment, and prognosis.

RESUMO As folhas de amora preta possuem algumas propriedades farmacológicas e um dos usos mais difundidos e estudados é para alivio dos sintomas do climatério e de outros durante o período pré-menstrual. Desta forma, a secagem se torna importante para a conservação e o armazenamento do produto até o seu uso ou processamento. Diante do exposto, objetivou-se com o presente estudo avaliar a cinética de secagem de folhas de amora preta, bem como determinar o coeficiente de difusão efetivo e a energia de ativação durante o processo de secagem. As folhas de amora preta foram submetidas à secagem em um secador experimental de leito fixo, em quatro condições controladas de temperatura (40, 50, 60 e 70 °C) e duas velocidades do ar de secagem (0,4 e 0,8 m s-1). Aos dados experimentais de razão de teor de água foram ajustados oito modelos matemáticos para representarem o processo de secagem em camada delgada de produtos agrícolas. Com base nos resultados obtidos, verificou-se que o modelo de Midilli foi o que melhor representou o fenômeno da secagem de folhas de amora preta. O aumento da temperatura e da velocidade do ar reduziu o tempo de secagem das folhas de amora preta, bem como aumentou os valores do coeficiente de difusão efetivo, sendo que esta relação pode ser descrita pela equação de Arrhenius, que apresenta uma energia de ativação para a difusão líquida durante a secagem de 65,94 e 66,08 kJ mol-1, para as velocidades do ar de secagem de 0,4 e 0,8 m s-1, respectivamente.
ABSTRACT Blackberry leaves have some pharmacological properties and one of the most widespread and studied uses is to relieve symptoms of the climacteric and other symptoms during the premenstrual period. Thus, drying becomes important for the conservation and storage of the product until its use or processing. The present study aimed to evaluate the drying kinetics of blackberry leaves, as well as to determine the effective diffusion coefficient and the activation energy during the drying process. Blackberry leaves were dried in an experimental fixed-bed dryer under four controlled temperature conditions (40, 50, 60 and 70 °C) and two drying air speeds (0.4 and 0.8 m s-1). With the experimental data of moisture ratio, eight mathematical models were fitted to represent the process of thin-layer drying of agricultural products. Based on the obtained results, it was found that the Midilli model represented best the phenomenon of drying of blackberry leaves. The increase in temperature and air speed reduced the drying time of blackberry leaves and increased the values of the effective diffusion coefficient. This relation can be described by the Arrhenius equation, which has an activation energy for the liquid diffusion during drying of 65.94 and 66.08 kJ mol-1, for drying air speeds of 0.4 and 0.8 m s-1, respectively.

Fundamento: A hipertrofia cardíaca constitui um dos componentes do remodelamento cardíaco e ocorre em resposta a aumento da atividade ou da sobrecarga funcional do coração. Objetivo: Avaliar a resposta hipertrófica da associação do hormônio tireoidiano e do exercício físico no coração de ratos. Método: Foram utilizados 37 ratos da linhagem Wistar, machos, adultos, distribuídos aleatoriamente em quatro grupos: controle, hormônio (HT), exercício (E), hormônio tireoidiano e exercício (H + E). O grupo hormônio recebeu diariamente levotiroxina sódica por gavagem, na dose de 20 μg de hormônio tireoidiano/100 g de peso corporal; o grupo exercício realizou natação cinco vezes por semana, com peso adicional correspondente a 20% do peso corporal, durante seis semanas; no grupo H + E foram aplicados simultaneamente os tratamentos dos grupos HT e E. A estatísica utilizada foi a análise de variância complementada, quando necessário, pelo teste de Tukey e o teste de correlação de Pearson. Resultados: O T4 foi mais elevado nos grupos HT e H + E. O peso total do coração foi maior nos grupos que receberam hormônio tireoidiano, e o peso ventricular esquerdo foi maior no grupo HT. O diâmetro transversal dos cardiomiócitos aumentou nos grupos HT, E e H + E. A porcentagem de colágeno foi maior nos grupos E e H + E. A análise da correlação entre as variáveis apresentou distintas respostas. Conclusão: A associação do hormônio tireoidiano com exercício físico de elevada intensidade produziu hipertrofia cardíaca e gerou um padrão hipertrófico não correlacionado diretamente ao grau de fibrose.
Background: Cardiac hypertrophy is a component of cardiac remodeling occurring in response to an increase of the activity or functional overload of the heart. Objective: Assess hypertrophic response of the association of thyroid hormone and exercise in the rat heart. Methods: We used 37 Wistar rats, male, adults were randomly divided into four groups: control, hormone (TH), exercise (E), thyroid hormone and exercise (H + E); the group received daily hormone levothyroxine sodium by gavage at a dose of 20 μg thyroid hormone/100g body weight, the exercise group took swimming five times a week, with additional weight corresponding to 20% of body weight for six weeks; in group H + E were applied simultaneously TH treatment groups and E. The statistics used was analysis of variance, where appropriate, by Tukey test and Pearson correlation test. Results: The T4 was greater in groups TH and H + E. The total weight of the heart was greater in patients who received thyroid hormone and left ventricular weight was greater in the TH group. The transverse diameter of cardiomyocytes increased in groups TH, E and H + E. The percentage of collagen was greater in groups E and H + E Correlation analysis between variables showed distinct responses. Conclusion: The association of thyroid hormone with high-intensity exercise produced cardiac hypertrophy, and generated a standard hypertrophy not directly correlated to the degree of fibrosis.

Objetivo Avaliar se o mês de nascimento em diferentes latitudes da América do Sul pode influenciar a presença ou gravidade da esclerose múltipla (EM) na vida. Método Neurologistas de quatro países da América do Sul trabalhando em unidades de EM coletaram os dados de seus pacientes com referência ao mês de nascimento, gênero, idade e progressão da doença. Resultados A análise dos dados mostrou que, para 1207 pacientes com EM e 1207 controles, não havia diferença significativa no mês de nascimento com relação à prevalência de EM em quatro zonas de latitude (0–10; 11–20; 21–30; e 31–40 graus). Não houve relação entre o mês de nascimento e a gravidade da doença em nenhuma destas zonas. Conclusão Os resultados deste estudo mostram que pacientes com EM nascidos de mães grávidas em diferentes latitudes sul não seguem o padrão dos resultados sazonais encontrados nas latitudes norte.
Objective To assess whether the month of birth in different latitudes of South America might influence the presence or severity of multiple sclerosis (MS) later in life. Methods Neurologists in four South American countries working at MS units collected data on their patients' month of birth, gender, age, and disease progression. Results Analysis of data from 1207 MS patients and 1207 control subjects did not show any significant variation in the month of birth regarding the prevalence of MS in four latitude bands (0–10; 11–20; 21–30; and 31–40 degrees). There was no relationship between the month of birth and the severity of disease in each latitude band. Conclusion The results from this study show that MS patients born to mothers who were pregnant at different Southern latitudes do not follow the seasonal pattern observed at high Northern latitudes.

Objective: To investigate the association between kidney dysfunction and haplotypes in sickle cell disease. Methods: A cohort of 84 sickle cell disease patients, treated in a public health service in Fortaleza, Brazil, was studied. Hemoglobin S haplotypes were obtained from 57 patients as they had recently received blood transfusions with 18 of them agreeing to undertake urinary concentrating ability and acidification tests. The glomerular filtration rate was estimated using the Modification of Diet in Renal Disease Study equation. Urinary concentration was evaluated utilizing the urinary and serum osmolality ratio (U/Posm) after 12 hours of water deprivation. Urinary acidification was evaluated by measuring the urinary pH before and after the administration of oral CaCl2. The analysis of the haplotypes of the beta S gene cluster was carried out by polymerase chain reaction-restriction fragment length polymorphism. The analysis of variance (ANOVA) test was used for multiple comparisons of means and the Newman-Keuls test was used to identify which groups were significantly different. Results: The mean age of the patients was 33 ± 13 years with 64.2% being females. The glomerular filtration rate was normal in 25 cases (30%) and a rate > 120 mL/min was seen in 52 cases (62%). Urinary concentration deficit was found in all patients who underwent the test and urinary acidification in 22%. There was no significant difference when comparing patients with the Bantu/Bantu and Benin/Benin haplotypes. On comparing patients with the Central African Republic-haplotype however, a higher number had glomerular filtration rates between 60 and 120 mL/min. Conclusion: There was no significant difference among sickle cell disease patients regarding the haplotypes and kidney dysfunction.

Introduction The incidence of American cutaneous leishmaniasis (ACL) is increasing in Latin America, especially in Brazil, where 256,587 cases were confirmed in the last decade. Methods This study used a Bayesian model to examine the spatial and temporal distribution of ACL cases between 2000 and 2009 in 61 counties of State of Maranhão located along the three main road and railway corridors. Results During the study period, 13,818 cases of ACL were recorded. There was a significant decrease in the incidence of ACL in the ten study years. The recorded incidence rate ranged from 7.36 to 241.45 per 100,000 inhabitants. The relative risk increased in 77% of the counties, decreased in 18% and was maintained in only five counties. Conclusions Although there was a decreased incidence of the disease, ACL was present in all of the examined municipalities, thus maintaining the risk of contracting this illness.

RESUMO Objetivo: Comparar eficácia e toxicidade da teicoplanina e da vancomicina em pacientes com infecção suspeita ou confirmada. Métodos: Fontes de dados: Cochrane Renal Group's Specialized Register, CENTRAL, MEDLINE, EMBASE, livros de referência e artigos de revisão. Critérios de inclusão: Ensaios clínicos controlados randomizados em qualquer idioma, comparando teicoplanina e vancomicina em pacientes com infecção suspeita ou confirmada. Extração de dados: Dois autores avaliaram a qualidade metodológica dos estudos e extraíram os dados de forma independente. Tentou-se obter dados não publicados diretamente com os autores de cada trabalho. Usou-se um modelo de efeito aleatório para estimar a razão de risco (RR) combinada, com um intervalo de confiança (IC) de 95%. Resultados: Foram incluídos 24 estudos (2.610 pacientes). As drogas tiveram taxas semelhantes de cura clínica (RR: 1,03; IC95%: 0,98-1,08), cura microbiológica (RR: 0,98; IC95%: 0,93-1,03) e mortalidade (RR: 1,02; IC95%: 0,79-1,30). A teicoplanina apresentou menores incidências de rash cutâneo (RR: 0,57; IC95%: 0,35-0,92), síndrome do homem vermelho (RR: 0,21; IC95%: 0,08-0,59) e eventos adversos em geral (RR: 0,73; IC95%: 0,53-1,00). A teicoplanina reduziu o risco de nefrotoxicidade (RR: 0,66; IC95%: 0,48-0,90). Esse efeito foi consistente em todos os subgrupos, inclusive aqueles com pacientes recebendo aminoglicosídeos concomitantes (RR: 0,51; IC95%: 0,300,88) ou com dosagens de vancomicina corrigidas pelo nível sérico (RR: 0,22; IC95%: 0,10-0,52). Não foi encontrado nenhum caso de injúria renal que necessitasse de diálise. Limitações: Os estudos não seguiram uma definição padrão de nefrotoxicidade. Conclusões: Teicoplanina e vancomicina têm eficácia semelhante; no entanto, o risco de nefrotoxicidade e outros eventos adversos foi menor com teicoplanina. É razoável considerar o uso de teicoplanina para pacientes em risco de desenvolver injúria renal aguda.
ABSTRACT Objective: To compare efficacy and safety of vancomycin versus teicoplanin in patients with proven or suspected infection. Methods: Data Sources: Cochrane Renal Group's Specialized Register, CENTRAL, MEDLINE, EMBASE, nephrology textbooks and review articles. Inclusion criteria: Randomized controlled trials in any language comparing teicoplanin to vancomycin for patients with proven or suspected infection. Data extraction: Two authors independently evaluated methodological quality and extracted data. Study investigators were contacted for unpublished information. A random effect model was used to estimate the pooled risk ratio (RR) with 95% confidence interval (CI). Results: A total of 24 studies (2,610 patients) were included. The drugs had similar rates of clinical cure (RR: 1.03; 95%CI: 0.98-1.08), microbiological cure (RR: 0.98; 95%CI: 0.93-1.03) and mortality (RR: 1.02; 95%CI: 0.79-1.30). Teicoplanin had lower rates of skin rash (RR: 0.57; 95%CI: 0.35-0.92), red man syndrome (RR: 0.21; 95%CI: 0.08-0.59) and total adverse events (RR: 0.73; 95%CI: 0.53-1.00). Teicoplanin reduced the risk of nephrotoxicity (RR: 0.66; 95%CI: 0.48-0.90). This effect was consistent for patients receiving aminoglycosides (RR: 0.51; 95%CI: 0.30-0.88) or having vancomycin doses corrected by serum levels (RR: 0.22; 95%CI: 0.10-0.52). There were no cases of acute kidney injury needing dialysis. Limitations: Studies lacked a standardized definition for nephrotoxicity. Conclusions: Teicoplanin and vancomycin are equally effective; however the incidence of nephrotoxicity and other adverse events was lower with teicoplanin. It may be reasonable to consider teicoplanin for patients at higher risk for acute kidney injury.
