- Abstract
Background: The Work Role Functioning Questionnaire 2.0 (WRFQ 2.0) is an important instrument within the context of occupational health, consisting of 27 items and 5 domains. In addition, a short version of WRFQ 2.0 with 5 items (WRFQ-5) was proposed, showing agreement with the long version. Thus, we aimed to confirm the number of factors of the WRFQ-5 short version and to verify the structural, construct, and criterion validity, reliability, internal consistency, and analysis of ceiling and floor effects of the Brazilian version of the WRFQ-5 in a general workers population., Methods: A questionnaire validation and measurement properties study. We evaluated the internal structure of the WRFQ-5 by means of confirmatory factor analysis. Construct validity was assessed by correlating the WRFQ-5 with the Numerical Pain Rating Scale (NPRS), Work Ability Index (WAI), and Self-Estimated Functional Inability because of Pain (SEFIP-work). Criterion validity was assessed by correlating the WRFQ-5 with the 5 domains of the WRFQ 2.0. Test-retest reliability and internal consistency were also evaluated., Results: We observed positive correlations (p < .05) between the WRFQ-5 and the WAI (rho = 0.161 to 0.308) and negative correlations (p < .05) between the WRFQ-5 and the SEFIP-work (rho = -0.293). The WRFQ-5 significantly and positively correlates with the 5 domains of WRFQ 2.0 (rho = 0.742 to 0.830). The test-retest reliability of the WRFQ-5 was excellent (ICC
2,1 = 0.935) and the internal consistency was adequate (Cronbach's alpha = 0.938). We did not observe ceiling and floor effects., Conclusion: The one-dimensional internal structure of the WRFQ-5 in Brazilian Portuguese has a valid internal structure and construct, as well as adequate reliability and internal consistency.- Published

- Abstract
Parasitemia and inflammatory markers are cross-sectionally associated with chronic Chagas cardiomyopathy (CCC) among patients with Trypanosoma cruzi . However, the prospective association of the parasite load and host immune response-related characteristics with CCC (that is, progressors) among T. cruzi seropositive individuals has only been partially defined. In a cohort of T. cruzi seropositive patients in Montes Claros and São Paulo, Brazil who were followed over 10 years, we identified the association of a baseline T. cruzi parasite load and systemic markers of inflammation with a decline in cardiac function and/or the presence of cardiac congestion 10 years later. The progressors ( n = 21) were individuals with a significant decline in the left ventricular ejection fraction and/or elevated markers of cardiac congestion after 10 years. The controls ( n = 31) had normal markers of cardiac function and congestion at the baseline and at the follow-up. They were matched with the progressors on age, sex, and genetic ancestry. The progressors had higher mean parasite loads at the baseline than the controls (18.3 vs. 0.605 DNA parasite equivalents/20 mL, p < 0.05). Of the 384 inflammation-related proteins analyzed, 47 differed significantly at a false discovery rate- (FDR-) corrected p < 0.05 between the groups. There were 44 of these 47 proteins that were significantly higher in the controls compared to in the progressors, including the immune activation markers CCL21, CXCL12, and HCLS1 and several of the tumor necrosis factor superfamily of proteins. Among the individuals who were seropositive for T. cruzi at the baseline and who were followed over 10 years, those with incident CCC at the 10-year marker had a comparatively higher baseline of T. cruzi parasitemia and lower baseline markers of immune activation and chemotaxis. These findings generate the hypothesis that the early impairment of pathogen-killing immune responses predisposes individuals to CCC, which merits further study.

- Abstract
The aim of this study was to examine aspects of children's health literacy; the information sources they were accessing, their information preferences, their perceived understanding of and their reported information needs in relation to COVID-19. An online survey for children aged 7-12 years of age and parent/caregivers from the UK, Sweden, Brazil, Spain, Canada and Australia was conducted between 6th of April and the 1st of June 2020. The surveys included demographic questions and both closed and open questions focussing on access to and understanding of COVID-19 information. Descriptive statistics and qualitative content analysis procedures were conducted. The findings show that parents are the main source of information for children during the pandemic in most countries (89%, n = 347), except in Sweden where school was the main source of information. However, in many cases parents chose to shield, filter or adapt their child's access to information about COVID-19, especially in relation to the death rates within each country. Despite this, children in this study reported knowing that COVID-19 was deadly and spreads quickly. This paper argues for a community rather than individual approach to addressing children's health literacy needs during a pandemic., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Brazil is the second largest ethanol producer in the world and largest using sugarcane feedstock. Bacteria contamination is one of the most important issues faced by ethanol producers that seek to increase production efficiency. Each step of production is a selection event due to the environmental and biological changes that occur. Therefore, we evaluated the influence of the selection arising from the ethanol production process on diversity and composition of bacteria. Our objectives were to test two hypotheses, (1) that species richness will decrease during the production process and (2) that lactic acid bacteria will become dominant with the advance of ethanol production. Bacterial community assemblage was accessed using 16S rRNA gene sequencing from 19 sequential samples. Temperature is of great importance in shaping microbial communities. Species richness increased between the decanter and must steps of the process. Low Simpson index values were recorded at the fermentation step, indicating a high dominance of Lactobacillus. Interactions between Lactobacillus and yeast may be impairing the efficiency of industrial ethanol production.

- Abstract
An inedited case in the Brazilian literature of conjunctival fibrous histiocytoma discovered during a wide scale community project accomplished by the team of the Center of Reference in Ophthalmology of the Hospital das Clínicas da Universidade Federal de Goiás in the Amazon region is reported. A 38 year-old caucasian woman presented with a vascularized lesion on the medial portion of the bulbar conjunctiva and caruncular region of the right eye with extension for the limbus and invading about 2 mm of the medial cornea resembling a pterygium. Pathologic findings revealed that the lesion was constituted by spindle-shaped cells, with storiform arrangement, and large histocytelike cells. The immunohistochemistry revealed strong positivity for vimentin and the neoplastic cells were negative for AE1/AE3, HMB 45, S 100 protein. The histopathologic diagnosis was fibrous histiocytoma. The evolution demonstrated the tumoral growth and the possibility of a malignant lesion.

- Abstract
This four-country study examined salivary cotinine as a marker for nicotine intake and addiction among smokers in relation to numbers and types of cigarettes smoked. Smoking characteristics of cigarette smokers in Brazil, China, Mexico, and Poland were identified using a standard questionnaire. Cotinine concentration was measured using a saliva sample from each participant; its relationship with numbers and types of cigarettes smoked was quantified by applying regression techniques. The main outcome measure was salivary cotinine level measured by gas chromatography. In all four countries, cotinine concentration increased linearly with cigarettes smoked up to 20 per day [11.3 ng/mL (95% confidence interval, 10.5-12.2)] and then stabilized as the number of cigarettes exceeded 20 [6.8 ng/mL per cigarette (95% confidence interval, 6.3-7.4) for up to 40 cigarettes]. On average, smokers of regular cigarettes consumed more cigarettes and had higher cotinine levels than light cigarette smokers. Cotinine concentration per cigarette smoked did not differ between regular and light cigarette smokers. Results suggest a saturation point for daily nicotine intake and minimal or no reduction in nicotine intake by smoking light cigarettes.

- Abstract
The Fogarty International Center (FIC) initiative, "International Tobacco and Health Research Capacity Building Program" represents an important step in US government funding for global tobacco control. Low- and middle-income countries of the world face a rising threat to public health from the rapidly escalating epidemic of tobacco use. Many are now parties to the Framework Convention on Tobacco Control (FCTC) and capacity development to meet FCTC provisions. One initial grant provided through the FIC was to the Institute for Global Tobacco Control (IGTC) at the Johns Hopkins Bloomberg School of Public Health (JHSPH) to support capacity building and research programmes in China, Brazil, and Mexico. The initiative's capacity building effort focused on: (1) building the evidence base for tobacco control, (2) expanding the infrastructure of each country to deliver tobacco control, and (3) developing the next generation of leaders as well as encouraging networking throughout the country and with neighbouring countries. This paper describes the approach taken and the research foci, as well some of the main outcomes and some identified challenges posed by the effort. Individual research papers are in progress to provide more in-depth reporting of study results.
