title: Cancer mortality among Brazilian painters of the South and Southeast Region of Brazil

description: Abstract As a result of their professional activity, painters come in regular contact with significant amounts of genotoxic and carcinogenic substances and may have increased risk for various diseases, including some cancers. This study aimed to compare the mortality by specific cancers among painters and the general population from the South and Southeast regions of Brazil from 1996 to 2013. Data on cancer deaths were obtained from the Brazilian Mortality Information System, according to ICD-10. To determine the risk of death from specific cancers, we calculated the mortality odds ratio (MOR), stratified by age (25-44 years and 45-64 years) and region. Older painters of the South and Southeast regions had a higher chance to die by oropharyngeal (MOR=1.73; 95% CI 1.51 to 1.98), hypopharynx (MOR=1.56; 95% CI 1.20 -2.03) and larynx cancer (MOR=1.45; 95% CI 1.32 to 1.61) when compared to the general population. These results suggest that painters may be at greater risk of becoming ill and dying from specific cancers from the upper respiratory tract.

title: Evaluation of zinc removal and compressive strength of self-reducing pellets composed of Electric Arc Furnace Dust

description: Abstract The amount of Electric Arc Furnace Dust (EAFD) is continuously increasing in mini-mill steel plants. This dust is considered a hazardous waste because of the presence of elements like lead, cadmium and chromium. Among many different treatment processes for this issue, there is the possibility of returning the EAFD back to the Electric Arc Furnace. This article presents a study of the compressive strength of self-reducing cold bonded pellets as well as their zinc removal, in an agglomerate containing EAFD, petroleum coke (PET) and Portland cement. The effects of the reductant and binder employed were discussed. Moreover, an apparatus was built to prevent zinc gas reoxidation inside an electric vertical laboratory furnace. Thus, the fraction of weight loss complemented the result of a previous study indicating the optimal content of PET source usage between 10 to 15%, in mass. Zinc removal and additional X Ray Diffraction outcomes are shown and discussed, concluding that 80% of zinc removal for this system could indicate the possibility of the EAFD reuse.

title: Depressive disorders in the elderly and dementia: An update

description: ABSTRACT The relationship between depressive disorders in the elderly and dementia, particularly Alzheimer’s disease (AD), is highly complex. While the nature of this relationship is still a matter of debate, differential diagnosis and treatment remain a great clinical challenge. We review recent findings on the conundrum of depressive disorders in the elderly and AD. There is a biological continuum between depressive disorders in the elderly – or at least a subgroup of them – and AD. While elderly subjects with depression and patients with AD exhibit higher circulating levels of pro-inflammatory molecules and lower BDNF than matched controls, CSF levels of Aβ42 can discriminate AD from depressive disorders in the elderly. The role of antidepressant treatment as a strategy to minimize the risk of AD remains to be established.

title: Dental care for children with Congenital Zika Syndrome

description: ABSTRACT There was a large increase in the number of newborns with microcephaly in Brazil between 2015 and 2017, mainly in the Northeast. This increase was associated with intrauterine Zika virus infection, which causes a congenital syndrome characterized by neurological, musculoskeletal, and sensory abnormalities. Despite the great worldwide repercussion, few studies about oral conditions in children with the syndrome have been published. This work aims to propose a guide for the dental care of these individuals on the basis of a literature review. Children with congenital Zika syndrome have a number of systemic comorbidities that affect their oral health and can compromise dental care. To date, no clinical protocol has been established for the dental care of children with congenital Zika syndrome. This is a pioneering study of great importance to orient dental professionals and promote the dental health of these children.

title: ‘An empty bag cannot stand upright’: The Bolsa Família Program and mortality caused by malnutrition

description: ABSTRACT The health of a person is the result of socioeconomic factors, especially those pertaining to preventable conditions, such as malnutrition in early childhood. Thus, this study investigated the relation between child mortality caused by malnutrition and the health measures of the Bolsa Família (Family Allowance) program in Brazil, comparing nationwide data with data from the state of Rio Grande do Sul. The Pearson correlation coefficient was used to analyze data from Bolsa Família (the number of families benefitting from the program, the health conditions it requires for eligibility, and the amount of money transferred to the families) in relation to malnutrition mortality rates among children under five, from 2005 to 2014. The data, collected between August and September 2016, were obtained from the Social Information Center (Matriz de Informação Social) of the Live Birth Information System (Sistema de Informações Sobre Nascidos Vivos) and the Mortality Information System (Sistema de Informações de Mortalidade) of Brazil. The results demonstrate that Bolsa Família functions by transferring income, which positively affects the nutrition of children, and that its intersectionality allows for better citizenship conditions for families, by broadening access to public services and participating in health promotion and disease prevention programs.

title: Germination of melon seeds under water and thermal stress

description: Abstract: Seeds vigor can influence seed performance under stress conditions. The objectives of this study were to evaluate the effect of water and thermal stress on germination and performance of melon seedlings, and to verify if germination under stress conditions is an efficient parameter to evaluate the vigor of these seeds. Four lots of ‘Golden Mine’ melon had their initial quality characterized by germination, first count, accelerated aging and seedling emergence tests. Germination under water stress was performed on a paper moistened with PEG 6000 solution at 0.06, -0.3, -0.6 and -0.9 MPa. The percentage and speed of germination, length and dry mass of the seedlings were evaluated. For the thermal stress experiment, cold test and germination at sub- (15 ºC) and supra-optimal (35 ºC) temperatures were performed, as well as at the ideal temperature (25 ºC). The germination of melon seeds under water stress induced by PEG 6000 at -0.3 and -0.6 MPa is an efficient method to detect differences in the physiological potential of lots of melon seeds, but these differences disappear under severe water stress (-0.9 MPa). Germination under sub-optimal temperatures also allows to identify differences in seeds performance and to classify them according to the vigor level.

title: Removal of entrained organic matter in the copper electrolyte by ozonation

description: Abstract Organic matter-in-aqueous entrainment is a serious problem in the hydrometallurgical extraction of copper from ore. Current inefficiencies, changes in the morphology and orientation of cathode deposit are some of the problems when organic matter is present in the advance electrolyte. In addition, negative effects upon metabolic activity of bioleaching microorganisms are reported due to entrained organic matter in the raffinate electrolyte. In view of these problems, the objective of this study was to evaluate ozonation as an alternative method for the removal of entrained organic matter present in an advanced electrolyte. For this purpose, ozonation during 30 min of synthetic solutions using a bubble glass column reactor at different ozone concentrations, flow rates and temperatures were studied. It was found that the increase in all of these operating parameters is not necessarily associated with an increase of the removal efficiency, and their effects on the mass transfer rate, chemical reaction rate, ozone solubility and contact time play a decisive role in the ozonation process. Thus, the best operating conditions were found at 6.7 wt.%, 1 L min-1 and 27 °C and reached a removal efficiency of 94.5%. This result demonstrated that removal of entrained organic matter in strongly acid solution by ozonation could be an alternative technology.

title: Creative activities, smart specialization, and opportunities for small urban areas: the Estarreja’s carnival case

description: Abstract In the context of consolidation of a society of knowledge, learning, and creativity, urban territories have had to readjust their strategies around creative activities, constituting new logic of territorial development and public policy. Building on the contextualization of smart specialization within the framework of European public policies and the importance of creative activities and resources, this study intends to identify new opportunities for small urban areas in order to redefine their local development strategies. The study aims to promote a debate on the valorization of cultural and creative dynamics that promote integrated and transversal development of the different actors and their territory. The municipality of Estarreja, Portugal, was used as a reference in the context of a small urban space with a past trajectory of industrial specialization, but with some current creative dynamics. In fact, this study intends to discuss the feasibility of applying this strategic matrix within the scope of current public development policies.

title: Analysis of reverse heat transfer for conventional and optimized lubri-cooling methods during tangential surface grinding of ABNT 1020 steel

description: Abstract A numerical thermal model was developed to evaluate the heat flux which is conducted to a rectangular workpiece of steel plate ABNT 1020, thus making it possible to compute the maximum temperature in the grinding surface, taking into account the rectangular distribution of heat flux, the thermal properties of the grinding wheel conventional Al2O3, the piece to be machined and the lubri-refrigerating fluid. The finite volume method was employed for the discretization of the direct thermal problem from the heat diffusion equation associated with the two-dimensional problem of heat conduction in transient regime. The inverse thermal problem was solved by the Golden Section technique. The thermal flux, when compared to the conventional technique of method of application fluid, was reduced by 84.0% in the practices performed with cutting depth of 30µm, at 74.0% in practices with cutting depth of 45µm and 61.2% in the aggressive practices of 60µm, thus demonstrating the applicability of the optimized method for fluid application.

title: Clinical impact of thyroglobulin (Tg) and Tg autoantibody (TgAb) measurements in needle washouts of neck lymph node biopsies in the management of patients with papillary thyroid carcinoma

description: ABSTRACT Objectives The presence of thyroglobulin (Tg) in needle washouts of fine needle aspiration biopsy (Tg-FNAB) in neck lymph nodes (LNs) suspected of metastasis has become a cornerstone in the follow-up of patients with papillary thyroid carcinoma (PTC). However, there are limited data regarding the measurement of anti-Tg antibodies in these washouts (TgAb-FNAB), and it is not clear whether these antibodies interfere with the assessment of Tg-FNAB or whether there are other factors that would more consistently justify the finding of low Tg-FNAB in metastatic LNs. Materials and methods We investigated 232 FNAB samples obtained from suspicious neck LNs of 144 PTC patients. These samples were divided according to the patient’s serum TgAb status: sTgAb- (n = 203 samples) and sTgAb+ (n = 29). The TgAb-FNAB levels were measured using two different assays. Tg-FNAB was also measured using two assays when low levels (&lt; 10 ng/mL) were identified in the first assay of the metastatic LNs from the sTgAb+ samples. Results The TgAb-FNAB results were negative in both assays in all samples. Low levels of Tg-FNAB were identified in 11/16 of the metastatic LNs of the sTgAb+ patients and 16/63 of the sTgAb- patients (p &lt; 0.05) using assay 1. The measurement of the Tg-FNAB levels using assay 2 indicated additional metastases in 5 LNs of the sTgAb+ patients. Conclusions Factors other than the presence of TgAb-FNAB may contribute to the higher number of metastatic LNs with undetectable Tg-FNAB in the sTgAb+ group. In addition, the measurement of Tg-FNAB using different assays was useful to enhance the diagnosis of metastatic LNs, particularly when cytological and Tg-FNAB results are discordant.
