title: Benzene exposure surveillance in gas stations’ work environments and production processes: a report on experience from the Cerest/Itaberaba, Bahia, Brazil

description: Abstract Introduction: benzene is highly harmful to health. Gas stations (GS) can offer a high risk of occupational exposure to this substance. Objective: to describe the experience of Centro de Referência em Saúde do Trabalhador de Itaberaba - Cerest/Itaberaba - (Occupational Health Reference Center of Itaberaba, in Bahia, Brazil) with surveillance of benzene occupational exposure in gas stations (GS). Methods: the actions taken were training of the Cerest/Itaberaba technicians; inspections in 12 GS were carried out in two stages - the first one to verify regulations conformities and the second to verify compliance with the requirements demanded at the first inspection. We analyzed data from Cerest’s training reports and inspection reports. Results: after Cerest intervention, there was a 2.2-fold increase in the number of conformities met by the GS; those which signed agreements with Ministério Público do Trabalho (Ministry of Public Labor Prosecution) showed higher increase than those which did not. Conclusion: the intersectoral experience promoted direct benefits to workers.

title: Wheat yield in the Cerrado as affected by nitrogen fertilization and inoculation with Azospirillum brasilense

description: Abstract: The objective of this work was to evaluate the effect of inoculation with Azospirillum brasilense, associated with N rates and sources, in soil of the Cerrado (Brazilian savanna), on the grain yield of irrigated wheat (Triticum aestivum). The experiment was carried out under a no-tillage system in a Typic Haplustox. The experimental design was randomized complete blocks with four replicates, in a 2x5x2 factorial arrangement: two N sources (urea and urea with NBPT urease inhibitor); five N rates applied as topdressing (0, 50, 100, 150, and 200 kg ha-1); and with or without seed inoculation with A.brasilense. The increase in the N rates positively affected spike length, number of spikelets and of grains per spike, number of spikes per meter, N accumulation in the straw, leaf chlorophyll content, and grain yield of irrigated wheat, regardless of the use of NBPT urease inhibitor with conventional urea. Singly, inoculation with A.brasilense does not affect production components and grain yield, despite the increase in N content in wheat straw. The inoculation with A.brasilense, associated with the application of 140 kg ha-1 N, provides the highest grain yield of irrigated wheat cropped after corn in low-altitude Cerrado.

title: Exposure to benzene in gas stations: strategy for integrated actions in Occupational Health Surveillance in Região dos Vales, Rio Grande do Sul, Brazil

description: Abstract Introduction: Benzene is an important source of environmental and occupational contamination and may cause poisoning to gas station workers. Objective: to report the benzene exposure surveillance experience carried out by the Centro de Referência em Saúde do Trabalhador (Occupational Health Reference Center) of Região dos Vales, in Rio Grande do Sul, Brazil. Methods: surveillance activities included regional mapping of gas stations, intrasectoral, intersectoral and inter-institutional actions, workplace inspections, development of a specific interventional instrument for this productive branch, and other approaches aiming to intervene in benzene exposure environments. Results: we observed alterations in biomarkers of effect and of exposure, besides companies inadequacies in clinical and laboratory monitoring of workers. In the work processes and the work environments inspected, situations that enlarged exposure were evident: inadequacies in fuel supply lanes, use of cloth strip for fuel leakage absorbance during tank filling, lack or shortage of collective protection measures, absence of volume electronic measurement of the storage tanks and absence of work cloths washing by the companies, among others. Conclusion: experiences unleashed through integrated actions in the health sector demonstrated the beneficial potentiality of the benzene exposure surveillance in gas stations.

title: Street-level Bureaucracy and Social Policy in Brazil

description: Abstract This paper describes the Brazilian central government bureaucracy and people with disabilities’ access to the Continuous Cash Benefit (BPC). This access depends on the Ministry of Social Security bureaucracy's evaluation of the condition of vulnerability. We performed a literature review, analysis of secondary data from time series and cross-sectional data to describe street-level federal bureaucracy. Legal documents and indicators describe the expert evaluation regimen of the Ministry of Social Security (MPS). This paper shows the uneven growth of the number of career public servants of the central government in the last two decades. The Brazilian central government has adopted the international concept of person with disabilities in the evaluation of BPC applicants. Despite this decision, it is shown that the Brazilian central government expanded selectively the career bureaucracy to work in the social area. It was found that the result of the evaluation process was quite strict, favoring applicants in conditions of extreme biomedical vulnerability. Despite adopting the social model, BPC eligibility is tied to medical diagnosis.

title: Contrast-induced acute kidney injury: the importance of diagnostic criteria for establishing prevalence and prognosis in the intensive care unit

description: ABSTRACT Objective: To establish whether there is superiority between contrast-induced acute kidney injury and contrast-induced nephropathy criteria as predictors of unfavorable clinical outcomes. Methods: Retrospective study carried out in a tertiary hospital with 157 patients undergoing radiocontrast infusion for propaedeutic purposes. Results: One hundred forty patients fulfilled the inclusion criteria: patients who met the criteria for contrast-induced acute kidney injury (59) also met the criteria for contrast-induced nephropathy (76), 44.3% met the criteria for KDIGO staging, 6.4% of the patients required renal replacement therapy, and 10.7% died. Conclusion: The diagnosis of contrast-induced nephropathy was the most sensitive criterion for renal replacement therapy and death, whereas KDIGO showed the highest specificity; there was no correlation between contrast volume and progression to contrast-induced acute kidney injury, contrast-induced nephropathy, support dialysis or death in the assessed population.

title: Transcriptional expression study in the central nervous system of rats: what gene should be used as internal control?

description: Objective A growing number of published articles report the expression of specific genes with different behavior patterns in rats. The levels of messenger ribonucleic acid transcripts are usually analyzed by reverse transcription followed by polymerase chain reaction and quantified after normalization with an internal control or reference gene (housekeeping gene). Nevertheless, housekeeping genes exhibit different expression in the central nervous system, depending on the physiological conditions and the area of the brain to be studied. The choice of a good internal control gene is essential for obtaining reliable results. This study evaluated the expression of three housekeeping genes (beta-actin, cyclophilin A, and ubiquitin C) in different areas of the central nervous system in rats (olfactory bulb, hippocampus, striatum, and prefrontal cortex). Methods Wistar rats (virgin females, n=6) during the diestrum period were used. Total ribonucleic acid was extracted from each region of the brain; the complementary deoxyribonucleic acid was synthesized by reverse transcription and amplified by real-time quantitative polymerase chain reaction using SYBR™ Green and primers specific for each one of the reference genes. The stability of the expression was determined using NormFinder. Results Beta-actin was the most stable gene in the hippocampus and striatum, while cyclophilin A and ubiquitin C showed greater stability in the prefrontal cortex and the olfactory bulb, respectively. Conclusion Based on our study, further studies of gene expression using rats as animal models should take into consideration these results when choosing a reliable internal control gene.

title: Kartogenin associated to micro of the subchondral bone in the joint cartilage repair in horses

description: ABSTRACT Articular cartilage reconstruction is still a challenge in Veterinary Medicine. The aim was to evaluate the therapeutic effects of kartogenin, a small molecule that promotes chondrocyte differentiation, in the repair of induced chondral defects pretreated with subchondral drilling. Six horses with a mean (± SD) weight of 342 ± 1.58Kg, aging 7.2 ± 1.30 years, and with a mean 7.1 ± 0.75 body score condition were used. In both stifles, a 1cm2 chondral defect was induced in the lateral femoral trochlea followed by treatment with subchondral drilling. Four intra-articular injections with kartogenin (20mM) were performed weekly in one stifle (treated group). The same procedure using saline solution was performed in the contralateral joint (control group). Clinical, radiographic, ultrasound evaluations were performed for a period of 60 days. No statistical differences were detected between groups in any of the studied variables. Although kartogenin has shown to improve articular cartilage repair in laboratory animal models, the same was not observed in this equine model. In conclusion, the kartogenin therapy, according to the used protocol, did not promote any clinical benefit in equine femoral trochlear defects pretreated with subcondral drilling.

title: Productive performance of blackberry cultivars in altitude region

description: ABSTRACT: Information on the production performance of blackberry in less colder regions are fundamentals to the expansion of the cultivated area and extension of management practices for cultivars adapted to climate conditions in Brazil. The research was carried out with the aim to evaluate the productive performance of different blackberries cultivars in altitude region of 1,387m with mild temperatures, situate at 18º14’56”S, 43º36’0”W, in Minas Gerais State, Brazil. It was carried during the seasons 2013/2014, 2014/2015 and 2015/2016. The blackberry cultivars evaluated were the following ones ‘Brazos’, ‘Guarani’, ‘Tupy’ and ‘Xavante’. Flowering and harvesting of cultivars were evaluated as well as climatological data of the area in order to relate the number of hours of accumulated cold less than 13°C, 10°C and 7.2°C with production and crop time. To determine the production, the mass of blackberries harvested per plant was measured. Production of blackberry cultivars was extended in altitude region with similar productivity to the other producing regions in Brazil. Productive performance of the cultivars varied according to the accumulation of cold hours with mild temperatures that occurred in cultivation region. ‘Brazos’, ‘Guarani’, ‘Tupy’ and ‘Xavante’ showed good adaptation, being ‘Brazos’ the cultivar most productive.
