title: Job precariousness: supply chain management in a waste pickers association

description: Abstract Os catadores de materiais recicláveis são atores fundamentais dentro da gestão dos resíduos sólidos municipais e um importante elo na cadeia da reciclagem. Os catadores realizam suas atividades em condições precárias: trabalham sob intempéries; correm o risco de acidentes de trânsito; entram em contato com insetos que transmitem doenças e sofrem com sobrecarga de peso. Tais condições se agravam diante da carência de direitos e garantias trabalhistas, além da instabilidade de rendimentos e exploração nos processos comerciais, recebendo preços irrisórios pelos materiais. Nesse contexto, a presente pesquisa busca, de forma interdisciplinar, a interface da gestão da cadeia de suprimentos com os aspectos que configuram a precarização do trabalho dos catadores, tendo como objetivo identificar e fomentar propostas de melhorias na infraestrutura e na cadeia de suprimentos de uma associação de catadores de materiais recicláveis, a partir do diálogo e da construção com os trabalhadores em questão. Para tanto, foi utilizada a análise ergonômica do trabalho para o levantamento de informações e elaboração de diagnóstico que subsidiou a construção de um mapa dos processos por meio da ferramenta SIPOC. A partir da análise documental do empreendimento, chegou-se ao resultado de parte do processo produtivo da associação, ou seja, sua recuperação de recicláveis no ano de 2018, que atingiu um volume de 141.893,7 kg. Buscou-se, com a presente pesquisa, proporcionar momentos de discussão reflexiva junto dos catadores sobre os processos organizativos da associação, de forma a construir coletivamente propostas que possibilitem melhores condições de trabalho para eles.

title: Influenza A virus circulation in pig nurseries in the state of Santa Catarina, Brazil

description: Abstract The objective of this work was to evaluate the infection caused by influenza A virus (IAV) subtypes and its incidence in pig nurseries in the state of Santa Catarina, Brazil. A total of 423 nursery pigs were sampled in 11 farms, and IAV circulation, viral RNA, and antibodies were identified. Reverse transcriptase quantitative polymerase chain reaction (RT-qPCR) was used to detect viral RNA in nasal swab samples (70.2%) and to subtype 33 viruses, of which 18 (54.5%) from six nurseries were the H3N2 virus, 6 (18.1%) from two nurseries were H1N1pdm, and 9 (27.2%) from three nurseries could not be subtyped. The enzyme-linked immunosorbent assay (ELISA) detected the presence of IAV antibodies (68%), which was confirmed by the hemagglutination inhibition test, revealing a higher prevalence of antibodies for the H3N2 virus (38.0%), followed by H1N1pdm (23.8%) and H1N2 (3.23%). The obtained data showed that 10.3% of the swine reacted to at least two viral antigens. There is a high prevalence of influenza A virus infection in all 11 piglets nurseries sampled by viral RNA and antibody detection. H3N2 and H1N1pdm, in this order, are the most detected viral subtypes in the 11 sampled nurseries.

title: Heart rate turbulence assessed through ergometry after myocardial infarction: a feasibility study

description: ABSTRACT BACKGROUND: Coronary artery disease is an important cause of morbidity and mortality. The impact of ventricular arrhythmias with impaired cardiac vagal activity is one of the most recently studied prognostic factors. However, there are no studies evaluating the phenomenon of heart rate turbulence (HRT) during physical exertion. OBJECTIVE: To study the behavior of HRT during exercise testing, among individuals after myocardial infarction. DESIGN AND SETTING: Feasibility study conducted in a university hospital among individuals 4-6 weeks after myocardial infarction. METHODS: All subjects underwent 24-hour Holter monitoring and ergometric stress testing. We considered that abnormal HRT was present if the turbulence onset was ≥ 0% or turbulence slope was ≤ 2.5 mm/relative risk interval. RESULTS: All 32 subjects were asymptomatic. Their median age was 58 years (interquartile range 12.8) and 70% were male. Abnormal HRT was associated with ventricular dysfunction in this population. We found no differences regarding the behavior of HRT, in relation to age, gender, smoking, systemic arterial hypertension, diabetes mellitus or dyslipidemia. Ergometric stress testing detected premature ventricular beats (PVB) in approximately 44% of the examinations, and these occurred both during the active phase of effort and in the recovery period. The low occurrence of several isolated PVB in beta-blocked subjects made it difficult to perform statistical analysis to correlate HRT between ergometric and Holter testing. CONCLUSION: The data obtained in this study do not support performing HRT through ergometric stress testing among patients who remain on beta-blockers post-myocardial infarction, for the purpose of assessing cardiac vagal activity.

title: Yield potential of modern soybean cultivars under high and low input levels

description: Abstract The objective of this work was to evaluate the grain yield potential of modern soybean (Glycine max) cultivars subjected to high- and low-input management levels on different sowing dates, in the southwestern region of the state of Paraná, Brazil. The experiment was carried out in the 2017/2018 and 2018/2019 crop seasons in the municipality of Itapejara D’Oeste. Five soybean cultivars (BMX Zeus IPRO, BMX Ativa RR, BMX Lança IPRO, NS 5445 IPRO, and NA 5909 RG) were evaluated in four environments formed by the combination of input management levels (high and low) and sowing dates (first and second). The experimental design was a randomized complete block with three replicates. The evaluated traits were: grain yield potential (kg ha-1), in the R5 phenological stage; and grain yield (kg ha-1) and its components, in the R8 stage. Cultivar, sowing date, and input management are determinant for maximizing grain yield potential. In the first sowing date, in October, the BMX Zeus IPRO cultivar shows a better response to the high level management, with a higher yield potential in the R5 stage (19,682 kg ha-1) and a higher grain yield (8,248 kg ha-1), whereas NA 5909 RG shows the best results with the low input management.

title: Relationship between motor coordination and executive function in adults and older adults

description: ABSTRACT Brazilian older adults present a relatively low schooling level when compared with other populations. In clinical practice, defining if more subtle alterations observed in executive function (EF) and motor coordination tests in older adults are due to an initial neurological condition or low schooling level is difficult. This study aimed to evaluate the possible differences in motor coordination and EF between adults and older adults with high and low schooling level as well as the possible correlations between motor coordination and EF in this sample. A total of 75 healthy individuals (aged from 30 to 89 years) were evaluated. EF was assessed by the trail making test (TMT) whereas motor coordination was assessed by the upper limb diadochokinetic test, which is the rapid alternation between supination and pronation of the forearms (right, left, both performing in-phase movements, and both performing anti-phase movements). Analysis of variance showed that age and schooling level possibly influenced EF and motor coordination. Possible relationships between EF and diadochokinesis were calculated by Pearson’s correlation. Older adults with low schooling level were significantly slower on the TMT part B (cognitive and motor) and delta TMT (cognitive). All groups were slower performing the anti-phase movement, especially those with low schooling level. Results showed only weak correlations between EF and motor coordination. Age and schooling level influenced executive function and motor coordination. However, the EF and motor coordination tests presented no correlation when these two factors were statistically corrected.

title: Phenology and production of traditional seeds of cowpea irrigated with saline water

description: ABSTRACT Cowpea suffers significant production losses when subjected to salt stress, but the response varies among genotypes. The objective of this study was to evaluate the phenology and production of traditional cowpea seeds under saline water irrigation. The experiment was conducted in two stages, the first one in a greenhouse to evaluate the phenology and production of cowpea genotypes and the second one in the laboratory to assess the viability and vigor of the seeds produced in the first stage. The treatments resulted from the combination of two salinity levels of the irrigation water (0.5 and 4.5 dS m-1) and 14 traditional cowpea varieties (Boquinha, Ceará, Costela-de-vaca, Lisão, Canário, Pingo-de-ouro, Roxão, Branco, Canapum-branco, Canapum-miúdo, Baêta, Coruja, Paulistinha, and Sempre-verde) acquired from traditional farmers in the western region of Rio Grande do Norte, Brazil. Canário, Baêta, and Coruja varieties have a higher number of flowers per plant and earlier flowering. Salinity reduced the number of flowers per plant, increased abortion in all traditional varieties and reduced production in the early varieties Branco, Canapum-miúdo, Baêta, and Coruja. Cultivation under saline water irrigation did not affect the viability of the seeds from the second generation of cowpea, but reduced the vigor of the seeds of the varieties Lisão, Pingo-de-ouro, Roxão, Branco, Canapum-branco, Canapum-miúdo, Baêta and Coruja. The traditional varieties Boquinha, Ceará, Costela-de-vaca, Canário, Paulistinha and Sempre-verde are indicated for the production of cowpea seeds under irrigation with saline water.

title: Blended Learning for teaching Renal Pathology in Medical Residency - a report

description: Abstract: Introduction: Blended Learning can be used as a pedagogical resource to the traditional ways of teaching. The lack of a Renal Pathology laboratory can result in a gap in the training of resident physicians in Nephrology. This study describes how complementing the content with the use of an online Renal Pathology atlas was described by resident physicians. Experience report: A virtual atlas of Renal Pathology prepared by preceptors of the Medical Residencies of Nephrology and Pathology was presented to eight resident physicians enrolled in the service, who, for fifteen days, included the studies of this content in their activities. The residents evaluated the teaching-learning experience through a focus group. Discussion: Online teaching strategies can be used to complement the knowledge acquired during Medical Residency. However, it is important that this stage of the blended learning strategy be motivating in the students’ view, adapting to the moment experienced by resident physicians, who already have a pre-determined workload. These points were among the emerging topics in the thematic analysis of the content of the focus group, which also included suggestions from the students on how to modify the content presentation. Conclusion: The inclusion of blended learning strategies can help the training of resident physicians, as well as open space for student production. Inter-institutional partnerships should be developed to overcome barriers to e-learning development by medical trainers.
