RESUMEN

BACKGROUND & AIMS: Information about the impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in patients with liver cancer is lacking. This study characterizes the outcomes and mortality risk in this population. METHODS: Multicentre retrospective, cross-sectional, international study of liver cancer patients with SARS-CoV-2 infection registered between February and December 2020. Clinical data at SARS-CoV-2 diagnosis and outcomes were registered. RESULTS: Two hundred fifty patients from 38 centres were included, 218 with hepatocellular carcinoma (HCC) and 32 with intrahepatic cholangiocarcinoma (iCCA). The median age was 66.5 and 64.5 years, and 84.9% and 21.9% had cirrhosis in the HCC and iCCA cohorts respectively. Patients had advanced cancer stage at SARS-CoV-2 diagnosis in 39.0% of the HCC and 71.9% of the iCCA patients. After a median follow-up of 7.20 (IQR: 1.84-11.24) months, 100 (40%) patients have died, 48% of the deaths were SARS-CoV-2-related. Forty (18.4%) HCC patients died within 30-days. The death rate increase was significantly different according to the BCLC stage (6.10% [95% CI 2.24-12.74], 11.76% [95% CI 4.73-22.30], 20.69% [95% CI 11.35-31.96] and 34.52% [95% CI 17.03-52.78] for BCLC 0/A, B, C and D, respectively; p = .0017). The hazard ratio was 1.45 (95% CI 0.49-4.31; p = .5032) in BCLC-B versus 0/A, and 3.13 (95% CI 1.29-7.62; p = .0118) in BCLC-C versus 0/A in the competing risk Cox regression model. Nineteen out of 32 iCCA (59.4%) died, and 12 deaths were related to SARS-CoV-2 infection. CONCLUSIONS: This is the largest cohort of liver cancer patients infected with SARS-CoV-2. It characterizes the 30-day mortality risk of SARS-CoV-2 infected patients with HCC during this period.

RESUMEN

BACKGROUND & AIMS: Information on safety and efficacy of systemic treatment in patients with hepatocellular carcinoma (HCC) under dialysis are limited due to patient exclusion from clinical trials. Thus, we aimed to evaluate the rate, prevalence, tolerability, and outcome of sorafenib in this population. METHODS: We report a multicenter study comprising patients from Latin America and Europe. Patients treated with sorafenib were enrolled; demographics, dose modifications, adverse events (AEs), treatment duration, and outcome of patients undergoing dialysis were recorded. RESULTS: As of March 2018, 6156 HCC patients were treated in 44 centres and 22 patients were concomitantly under dialysis (0.36%). The median age was 65.5 years, 40.9% had hepatitis C, 75% had Child-Pugh A, and 85% were Barcelona Clinic Liver Cancer-C. The median time to first dose modification, treatment duration and overall survival rate were 2.4 months (interquartile ranges [IQR], 0.8-3.8), 10.8 months (IQR, 4.5-16.9), and 17.5 months (95% CI, 7.2-24.5), respectively. Seventeen patients required at least 1 dose modification. The main causes of first dose modification were asthenia/worsening of Eastern Cooperative Oncology Group-Performance Status and diarrhoea. At the time of death or last follow-up, four patients were still on treatment and 18 had discontinued sorafenib: 14 were due to tumour progression, 2 were sorafenib-related, and 2 were non-sorafenib-related AE. CONCLUSIONS: The outcomes observed in this cohort seem comparable to those in the non-dialysis population. Thus, to the best of our knowledge, this is the largest and most informative dataset regarding systemic treatment outcomes in HCC patients undergoing dialysis.

RESUMEN

Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest. No copyright restrictions are associated with the data set. Please cite this Ecology Data Paper if the data are used in publication and teaching events.

RESUMEN

INTRODUCTION AND AIM: Sorafenib has been the standard of care for first-line treatment of advanced hepatocellular carcinoma, a complex disease that affects an extremely heterogenous population. Thereby requiring multidisciplinary individualized treatment strategies that match the disease characteristics and the patients' specific needs. MATERIAL AND METHODS: Data for 175 patients who received sorafenib for hepatocellular carcinoma in three different hospitals in Sao Paulo, Brazil over a span of nine years were retrospectively analyzed. RESULTS: The median age was 62 years. Percentages of patients with Child-Pugh A, B and C liver cirrhosis were 61%, 31% and 5%, respectively. Approximately half of the patients had Barcelona Clinic Liver Cancer stage B disease, and the other half had stage C. The median treatment duration was 253 days. Sorafenib dose was reduced to 400 mg/day in 41% of the patients due to toxicity. Overall objective response rate as per Response Evaluation Criteria in Solid Tumors and its modified version was 39%. Patients who received transarterial chemoembolization (TACE) at any point during sorafenib therapy were significantly more likely to experience an objective response. After a median follow-up of 339 days, the median overall survival was 380 days. Child-Pugh cirrhosis, tumor response and concomitant chemoembolization were independent prognostic factors for overall survival in multivariate analysis. CONCLUSION: Our results suggest that, in experienced hands, sorafenib therapy may benefit carefully selected hepatocellular carcinoma patients for whom other therapies are initially contraindicated, including those patients with Child-Pugh B liver function and those patients who are subsequently treated with concomitant TACE.

RESUMEN

BACKGROUND: CD64 (FcγR1) is a high-affinity receptor for monomeric IgG1 and IgG3. Circulating neutrophils express very low amounts of CD64 on their surface. OBJECTIVES: Our primary aim was to investigate the utility of neutrophil CD64 surface expression as a biomarker of active pulmonary tuberculosis (TB). We hypothesised that elevated neutrophil CD64 expression in TB infection would be associated with interferon gamma (IFN-γ) as an inducer of CD64 expression. METHODS: The expression level of CD64 per neutrophil (PMN CD64 index) was quantitatively measured with flow cytometry using a Leuko64 kit in samples from patients with TB and latent TB infection (LTBI) as well as healthy controls, as part of a prospective cohort study in Brazil. FINDINGS: The PMN CD64 index in patients with TB was higher than that in healthy controls and LTBI. Receiver operating characteristic curve analyses determined that the PMN CD64 index could discriminate patients with TB from those with LTBI and healthy individuals. PMN CD64 index levels returned to baseline levels after treatment. CONCLUSIONS: The positive regulation of CD64 expression in circulating neutrophils of patients with active TB could represent an additional biomarker for diagnosis of active TB and could be used for monitoring individuals with LTBI before progression of TB disease.

RESUMEN

AIM: To evaluate the effects of HepaSphere 50-100 µm (Merit Medical) as a doxorubicin carrier and embolization agent for the treatment of hepatocellular carcinoma (HCC). MATERIAL AND METHODS: A prospective analysis of 18 patients recruited from a national cancer center was conducted. This analysis evaluated the efficacy and safety of HepaSphere, as expressed by the treatment response rate (measured by the modified Response Evaluation Criteria in Solid Tumors, mRECIST) and by the prevalence of treatment-related adverse events, respectively. RESULTS: The cohort was predominantly male, with a mean age of 69 years. The objective response rate (complete + partial response) was 53.3%. The variable most likely to be associated with objective response was Barcelona Clinic Liver Cancer (BCLC) staging. The most prevalent adverse events were nausea, vomiting and abdominal pain. CONCLUSION: HepaSphere chemoembolization yielded a substantial objective response rate with an acceptable toxicity profile and should be considered an option for HCC treatment.

RESUMEN

BACKGROUND: Mutations in the mitochondrial DNA (mtDNA) have been associated with aminoglycoside-induced and nonsyndromic deafness in different populations. In the present study, we investigated the contribution of mutations in mitochondrial genes to the etiology of hearing loss in a Brazilian sample. METHODS: Using mass spectrometry genotyping technology, combined with direct sequencing, 50 alterations previously described in 14 mitochondrial genes were screened in 152 patients with sensorineural hearing loss and in104 normal hearing controls. RESULTS: Fifteen known mitochondrial alterations were detected (G709A, A735G, A827G, G988A, A1555G, T4363C, T5628C, T5655C, G5821A, C7462T, G8363A, T10454C, G12236A, T1291C, G15927A). Pathogenic mutations in MT-RNR1 and MT-TK genes were detected in 3 % (5/152) of the patients with hearing loss. CONCLUSIONS: This study contributed to show the spectrum of mitochondrial variants in Brazilian patients with hearing loss. Frequency of A1555G was relatively high (2.6 %), indicating that this mutation is an important cause of hearing loss in our population. This work reports for the first time the investigation and the detection of the tRNA(Lys) G8363A mutation in Brazilian patients with maternally inherited sensorineural hearing loss.

RESUMEN

PURPOSE: Leber hereditary optic neuropathy (LHON) is a mitochondrial disease characterized by bilateral vision loss. More than 95% of LHON cases are associated with one of the three main mtDNA mutations: G11778A, T14484C, and G3460A. The other 5% of cases are due to other rare mutations related to the disease. The aim of this study was to identify the prevalence and spectrum of LHON mtDNA mutations, including the haplogroup, in a cohort of Brazilian patients with optic neuropathy and to evaluate the usefulness of iPLEX Gold/matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) technology in detecting LHON mutations. METHODS: We analyzed a total of 101 patients; 67 had a clinical diagnosis of LHON and 34 had optic neuropathy of unknown etiology. Direct sequencing and iPLEX Gold/MALDI-TOF MS were used to screen for the most common pathogenic point mutations in LHON, together with the rare mutations G3733A, C4171A, T10663C, G14459A, C14482G, A14495G, C14568T, and C14482A. RESULTS: We identified mutations in 36 patients, of whom 83.3% carried the G11778A mutation and 16.7% carried the T14484C mutation. In individuals with mutations, the haplogroups found were L1/L2, L3, C, R, U, D, and H. Rare mutations were not detected in any of the patients analyzed. CONCLUSIONS: The frequencies of the main LHON mutations were similar to those previously reported for Latin America. A different frequency was found only for the A3460G mutation. The most frequent haplogroups identified were of African origin. The iPLEX Gold/MALDI-TOF MS technology proved to be highly accurate and efficient for screening mutations and identifying the haplogroups related to LHON. The MassArray platform, combined with other techniques, enabled definitive diagnosis of LHON in 36% (36/101) of the cases studied.

RESUMEN

(1) Background: The identification of microorganisms includes traditional biochemical methods, molecular biology methods evaluating the conserved regions of rRNA, and the molecular biology of proteins (proteomics), such as MALDI-TOF MS mass spectrometry. This work aimed to identify the biodiversity of yeasts associated with stingless bee species' honey and pollen, Melipona scutellaris, Nannotrigona testaceicornes, and Tetragonisca angustula, from the region of São Gonçalo dos Campos-Bahia (BA) state, Brazil. (2) Methods: Cellular proteins were extracted from 2837 microbial isolates (pollen and honey) and identified via MALDI-TOF MS. The identified yeast species were also compared to the mass spectra of taxonomically well-characterized reference strains, available from the National Center of Biotechnology Information (NCBI) database. (3) Results: Nine yeast species were identified: Candida maltosa, Candida norvegica, Kazachstania telluris, Schizosaccharomyces pombe, Scheffersomyces insectosus, Meyerozyma guilliermondii, Brettanomyces bruxellensis, Kazachstania exigua, and Starmerella lactis-condensi. Nannotrigona testaceicornes pollen had the highest number of yeast colonies. The yeasts Brettanomyces bruxellensis and Kazachstania telluris showed high populations in the samples of Nannotrigona testaceicornes and Melipona scutellaris, respectively. This work shows that there is some sharing of the same species of yeast between honey and pollen from the same beehive. (4) Conclusions: A total of 71.84% of the identified species present a high level of confidence at the species level. Eight yeast species (Candida maltosa, Candida norvegica, Kazachstania telluris, Schizosaccharomyces pombe, Scheffersomyces insectosus, Meyerozyma guilliermondii, Kazachstania exigua, and Starmerella lactis-condensi) were found for the first time in the samples that the authors inspected. This contributes to the construction of new knowledge about the diversity of yeasts associated with stingless bee products, as well as to the possibility of the biotechnological application of some yeast species.

RESUMEN

OBJECTIVES: Evatuate if Bacillus Calmette-Guérin (BCG) vaccine could be used as a tool against SARS-CoV-2 based on the concept of trained immunity. METHODS: A multicenter, double-blinded, randomized clinical trial recruited health care workers (HCWs) in Brazil. The incidence rates of COVID-19, clinical manifestations, absenteeism, and adverse events among HCWs receiving BCG vaccine (Moreau or Moscow strains) or placebo were compared. BCG vaccine-mediated immune response before and after implementing specific vaccines for COVID-19 (CoronaVac or COVISHIELD) was analyzed. Cox proportional hazard and linear mixed effect modeling were used. RESULTS: A total of 264 volunteers were included for analysis (BCG = 134 and placebo = 130). The placebo group presented a COVID-19 cumulative incidence of 0.75% vs 0.52% of BCG. The Moreau strain also presented a higher incidence rate (1.60% × 0.22%). BCG did not show a protective hazard ratio against COVID-19. In addition, the log (immunoglobulin G) level against SARS-CoV-2 presented a higher increase in the BCG group, whether or not participants had COVID-19, but also without statistical significance. CONCLUSION: Our results suggest that BCG has a tendency of protection against SARS-CoV-2 and higher immunoglobulin G levels than placebo. The clinical trial was registered at https://clinicaltrials.gov/ (NCT04659941).

RESUMEN

Hepatocellular carcinoma (HCC) is the third most common cause of cancer-related mortality worldwide. The Brazilian Society of Hepatology (SBH) published in 2020 the updated recommendations for the diagnosis and treatment of HCC. Since then, new data have emerged in the literature, including new drugs approved for the systemic treatment of HCC that were not available at the time. The SBH board conducted an online single-topic meeting to discuss and review the recommendations on the systemic treatment of HCC. The invited experts were asked to conduct a systematic review of the literature on each topic related to systemic treatment and to present the summary data and recommendations during the meeting. All panelists gathered together for discussion of the topics and elaboration of the updated recommendations. The present document is the final version of the reviewed manuscript containing the recommendations of SBH and its aim is to assist healthcare professionals, policy-makers, and planners in Brazil and Latin America with systemic treatment decision-making of patients with HCC.

RESUMEN

The bee Melipona scutellaris is considered the reared meliponine species with the largest distribution in the North and Northeast regions of Brazil, with records from the state of Rio Grande do Norte down to the state of Bahia. Considering the importance of this species in the generation of income for family agriculture and in the preservation of areas with natural vegetation, this study aimed at providing knowledge on the distribution of natural colonies of M. scutellaris in the state of Bahia. Literature information, interviews with stinglessbee beekeepers, and expeditions were conducted to confirm the natural occurrence of the species. A total of 102 municipalities showed records for M. scutellaris, whose occurrence was observed in areas ranging from sea level up to 1,200-meter height. The occurrence of this species in the state of Bahia is considered to be restricted to municipalities on the coastal area and the Chapada Diamantina with its rainforests. Geographic coordinates, elevation, climate and vegetation data were obtained, which allowed a map to be prepared for the area of occurrence in order to support conservation and management policies for the species.

RESUMEN

Hepatocellular carcinoma (HCC) is the sixth most common cancer in the world in terms of incidence, accounting for approximately 630 thousand new cases per year; in addition, HCC is the third most common cause of cancer death. Worldwide, the greatest risk factors for HCC are the infections caused by hepatitis B and C viruses, which increase the risk of developing the disease by about 20 times. The standard treatment in the early stages of the disease, such as surgical resection, local ablation and liver transplantation, are able to cure a proportion of patients, but most cases of HCC present in advanced stages, precluding the use of such treatments with curative intent. In these advanced stages, systemic treatments are commonly used. Unfortunately, chemotherapy with conventional cytotoxic agents is ineffective and does not seem to modify the natural history of disease. Treatment options for patients with advanced HCC are extremely limited, but the identification of signaling pathways, and the recognition of the role of these pathways in the pathogenesis of the disease resulted in the development of drugs directed at specific therapeutic targets. One such drug is Sorafenib, a kinase inhibitor with antiangiogenic and antiproliferative properties. In conclusion, Sorafenib has demonstrated survival benefits in patients with advanced HCC, thus representing a new standard reference for systemic treatment in these cases.

RESUMEN

This study was conducted to evaluate the effect of a dehumidification process on the physicochemical and sensory characteristics of stingless-bee honey. Melipona scutellaris and M. quadrifasciata honey samples were submitted to a dehumidification process and to physicochemical (reducing sugars, apparent sucrose, moisture, diastatic activity, hydroxymethylfurfural, ash, pH, acidity, and electric conductivity) and sensory evaluations (fluidity, color, aroma, crystallization,flavor,and acceptability). The results indicated that the dehumidification process does not interfere with honey quality and acceptability.

RESUMEN

OBJECTIVE: Clinical trials have shown that nintedanib 150 mg twice daily (bid) reduces disease progression in patients with idiopathic pulmonary fibrosis (IPF), with an adverse event profile that is manageable for most patients. Prior to the approval of nintedanib as a treatment for IPF in Brazil, an expanded access program (EAP) was initiated to provide early access to treatment and to evaluate the safety and tolerability of nintedanib in this patient population. METHODS: Patients with a diagnosis of IPF within the previous five years, forced vital capacity (FVC) ≥ 50% predicted and diffusing capacity of the lungs for carbon monoxide (DLco) 30% to 79% predicted were eligible to participate in the EAP. Patients received nintedanib 150 mg bid open-label. Safety assessments included adverse events leading to permanent discontinuation of nintedanib and serious adverse events. RESULTS: The EAP involved 57 patients at eight centers. Most patients were male (77.2%) and white (87.7%). At baseline, mean (SD) age was 70.7 (7.5) years and FVC was 70.7 (12.5) % predicted. Mean (SD) exposure to nintedanib was 14.4 (6.2) months; maximum exposure was 22.0 months. The most frequently reported adverse events considered by the investigator to be related to nintedanib treatment were diarrhea (45 patients, 78.9%) and nausea (25 patients, 43.9%). Adverse events led to permanent discontinuation of nintedanib in 16 patients (28.1%). Sixteen patients (28.1%) had a serious adverse event. CONCLUSION: In the Brazilian EAP, nintedanib had an acceptable safety and tolerability profile in patients with IPF, consistent with data from clinical trials.


OBJETIVO: Ensaios clínicos mostraram que 150 mg de Nintedanibe duas vezes ao dia reduzem a progressão da doença em pacientes com Fibrose Pulmonar Idiopática (FPI), com um perfil de efeitos adversos que é controlável para a maioria dos pacientes. Antes da aprovação do Nintedanibe como tratamento para a FPI no Brasil, um Programa de Acesso Expandido (PEA) foi iniciado para fornecer acesso precoce ao tratamento e avaliar a segurança e a tolerância do Nintedanibe para este grupo de pacientes. MÉTODOS: Foram elegíveis para participar da PEA pacientes com diagnóstico de FPI nos últimos 5 anos, com capacidade vital forçada (CVF) ≥ 50% do previsto e capacidade de difusão dos pulmões para monóxido de carbono (DLco) 30%-79% do previsto. Os pacientes receberam Nintedanibe 150 mg, 2 vezes ao dia (bid). As avaliações de segurança incluíram eventos adversos que levaram à suspensão permanente do Nintedanibe e eventos adversos graves. RESULTADOS: O PEA envolveu 57 pacientes em 8 centros. A maioria dos pacientes era do sexo masculino (77,2%) e brancos (87,7%). No início do estudo, a média de idade foi de 70,7 (7,5) anos e a CVF foi de 70,7 (12,5%) do previsto. A média de exposição ao Nintedanibe foi de 14,4 (6,2) meses; a exposição máxima foi de 22,0 meses. Os eventos adversos frequentemente relatados pelo pesquisador como relacionados ao tratamento com Nintedanibe foram diarreia (45 pacientes, 78,9%) e náusea (25 pacientes, 43,9%). Os eventos adversos levaram à suspensão permanente do Nintedanibe em 16 pacientes (28,1%) que passaram por um evento adverso grave. CONCLUSÕES: No PEA brasileiro, o Nintedanibe apresentou um perfil aceitável de segurança e tolerância em pacientes com FPI, condizendo com dados de ensaios clínicos.

RESUMEN

Neste estudo, examinamos as atividades de lazer entre os professores durante a COVID-19, avaliando questões relacionadas ao perfil sociodemográfico e às condições de trabalho. Trata-se de um websurvey transversal, realizado com professores da educação básica pública de Minas Gerais. Foi utilizado um formulário digital para a coleta de dados em 2020. A prática de lazer na pandemia foi a variável dependente. Na análise múltipla, foi utilizada a regressão de Poisson. Participaram do estudo 15.641 professores, dos quais 43% não estavam tendo práticas de lazer na pandemia. Houve maior prevalência de ausência da prática de lazer entre as mulheres, entre os idosos, professores pardos e pretos, contratados/designados e insatisfeitos com o trabalho docente na pandemia. Assim, esta pesquisa buscou discutir temas socioculturais, destacando que o acesso às práticas de lazer carece de uma visão social, humana e voltada para a desigualdade.


In this study, we examined leisure activities among teachers during the COVID-19, assessing issues related to sociodemographic profile and working conditions. This is a cross-sectional websurvey, performed with teachers of public basic education of Minas Gerais. A digital form was used to collect data in 2020. Leisure practice in pandemic was the dependent variable. In the multiple analysis, Poisson regression was used. A total of 15,641 teachers participated in the study, of which 43% were not having leisure practices in pandemic. There was a higher prevalence of absence of leisure practice among women, among the elderly, brown and black-skinned teachers, contracted/designated teachers and those not satisfied with teaching work in pandemic. Thus, this research sought to discuss sociocultural topics, highlighting, that access to leisure practices lacks a social, human vision focused on the inequality.

RESUMEN

ABSTRACT Hepatocellular carcinoma (HCC) is the third most common cause of cancer-related mortality worldwide. The Brazilian Society of Hepatology (SBH) published in 2020 the updated recommendations for the diagnosis and treatment of HCC. Since then, new data have emerged in the literature, including new drugs approved for the systemic treatment of HCC that were not available at the time. The SBH board conducted an online single-topic meeting to discuss and review the recommendations on the systemic treatment of HCC. The invited experts were asked to conduct a systematic review of the literature on each topic related to systemic treatment and to present the summary data and recommendations during the meeting. All panelists gathered together for discussion of the topics and elaboration of the updated recommendations. The present document is the final version of the reviewed manuscript containing the recommendations of SBH and its aim is to assist healthcare professionals, policy-makers, and planners in Brazil and Latin America with systemic treatment decision-making of patients with HCC.


RESUMO O carcinoma hepatocelular (CHC) é uma das principais causas de mortalidade relacionada a câncer no Brasil e no mundo. A Sociedade Brasileira de Hepatologia (SBH) publicou em 2020 a atualização das recomendações da SBH para o diagnóstico e tratamento do CHC. Desde então, novas evidências científicas sobre o tratamento sistêmico do CHC foram relatadas na literatura médica, incluindo novos medicamentos aprovados que não estavam disponíveis na época do último consenso, levando a diretoria da SBH a promover uma reunião monotemática on-line para discutir e rever as recomendações sobre o tratamento sistêmico do CHC. Um grupo de experts foi convidado para realizar uma revisão sistemática da literatura e apresentar uma atualização, baseada em evidências científicas, sobre cada tópico relacionado ao tratamento sistêmico e a apresentar os dados e recomendações resumidas durante a reunião. Todos os painelistas se reuniram para discutir os tópicos e elaborar as recomendações atualizadas. O presente documento é a versão final do manuscrito revisado, contendo as recomendações da SBH, e seu objetivo é auxiliar os profissionais de saúde, formuladores de políticas e planejadores no Brasil e na América Latina na tomada de decisões sobre o tratamento sistêmico de pacientes com CHC.

RESUMEN

This study investigated the profile of orchidists, their cultivation practices, and their knowledge about pests in orchid cultivation in the state of Bahia. There were applied 74 questionnaires to producers (amateurs and commercials) in 23 municipalities. The data were submitted to univariate statistics using the chi-square test, the Mann­Whitney U-test and the Kruskal­Wallis H-test. The survey shows that orchid cultivation is mostly practiced by women (67.6%) and those with higher education (48.7%). Most respondents were amateurs (87.8%). Insects (39.9%) and diseases (32.5%) were the main organisms associated with phytosanitary problems. The presence of insects was reported to occur mainly in the leaves (47%), mainly mealybugs (46.3%). Correspondence was significant between commercial and amateur groups according to the pairwise Mann­Whitney U-test(1) = 370.04 and p < 0.01. The Kruskal­Wallis H-test(27) = 924.78 and p < 0.01 discriminated categories between the groups. Despite the growing interest in orchid cultivation in the state of Bahia, most orchidists are amateurs. The study warns about the risk of pest dispersion between crops since exchanging plants and purchasing specimens in open markets are common practices.

RESUMEN

Resumo Este estudo objetivou analisar o desenvolvimento de aspectos modernos na cidade de Montes Claros, na primeira metade do século XX, localizada no Norte do estado de Minas Gerais, e problematizou as tensões sociais existentes entre a aquisição de novos hábitos e as antigas tradições locais. Foram buscadas informações na imprensa jornalística da época, a partir do periódico Gazeta do Norte, o jornal de maior circulação da cidade de Montes Claros no período de 1918 a 1962. Identificou-se que, no sertão do Brasil do século XX, as diversões se constituíram em meio a tensões entre a tradição e o moderno. Para além disto, o tempo e o espaço locais estabeleceram relações com a formação do binômio trabalho e divertimento em Montes Claros. O advento da modernidade permitiu a apropriação, não sem resistências e tensões, de um conjunto de valores e práticas que se distinguiam das vigentes no ordenamento social até então.


Abstract This study analyzed the development of modern aspects of life in the first half of the 20th century in the city of Montes Claros, northern Minas Gerais, Brazil, and discussed the social tensions between acquisition of new habits and old local traditions. Information was sought from Gazeta do Norte, the most widely read newspaper in the city in 1918-1962. The study found that, in the Brazilian hinterland (known as sertão) of the 20th Century, forms of amusement were created amid tensions between tradition and the modernity. In addition, local time and space have established relations with the work/entertainment binomial in Montes Claros. The advent of modernity allowed appropriation - not without resistance and tensions - of a set of values and practices that were different from those that had prevailed in the social order so far.


Resumen Este estudio tuvo como objetivo analizar el desarrollo de aspectos modernos en la ciudad de Montes Claros, ubicada en el norte del estado de Minas Gerais, en la primera mitad del siglo XX, y problematizó las tensiones sociales existentes entre la adquisición de nuevos hábitos y las antiguas tradiciones locales. Se buscó información en la prensa de la época a partir del periódico Gazeta do Norte, el diario de mayor circulación en la ciudad de Montes Claros en el período de 1918 a 1962. Se identificó que, en el semiárido brasileño del siglo XX, las diversiones se constituyeron en medio a tensiones entre la tradición y la modernidad. Además, el tiempo y el espacio locales establecieron relaciones con la formación del binomio trabajo y entretenimiento en Montes Claros. El advenimiento de la modernidad permitió la apropiación, no sin resistencias y tensiones, de un conjunto de valores y prácticas que se diferenciaban de las imperantes en el orden social hasta entonces.

RESUMEN

Este estudo versa sobre os sentidos atribuídos pelos frequentadores de um projeto denominado "Forró na Praça" à vivência da dança no espaço público da praça, sendo este espaço parte constitutiva da cidade, presente na realidade com seus objetos e formado pela contínua interação humana. Para desenvolvimento desta pesquisa foram realizadas observações simples das aulas de dança do projeto e aplicadas entrevistas semiestruturadas ao coordenador do projeto e a três participantes. Os dados coletados foram analisados segundo análise qualitativa do conteúdo, sendo constatado que o dançar na praça promove sociabilidade e novas experiências, podendo se constituir em uma vivência de lazer significativa para os participantes. A praça, pública e aberta, convida "facilmente" aqueles que ocupam e percorrem a cidade a viver a dança neste espaço/paisagem.

This space is a constituent part of the city, present in reality with its objects and formed by continuous human interaction. For the development of this research, simple observations were made of the dance classes held in the project and semi-structured interviews were applied to the project coordinator and to three participants. The collected data were interpreted according to the qualitative content analysis procedures. From this analysis, it was possible to verify that the possibility of dancing in the square promotes sociability and new experiences, which can constitute a significant leisure experience for the participants. The square, public and open, invites "easily" those who occupy and travel the city to live the dance in this space/landscape.
