title: Two-wheeled vulnerability: trend and demographic profile of mortality caused by motorcycle traffic violence in Brazil, 2004-2014

description: Abstract Objective To analyze mortality trend among motorcyclists caused by traffic accidents, and to analyze the demographic profile of the victims. Method This study is a historical series which aims to evaluate the average variation of deaths among motorcyclists in the Brazilian macro-regions; correlation between deaths and the circulating fleet; raw and standardized mortality rates calculated according to age, gender, race, schooling, and work accident. Results A significantly increase on mortality trend was observed among motorcyclists in the Brazilian macro-regions (p-value &lt;0.001). Based on the raw and standardized mortality rates among motorcyclists, it is possible to state that deaths are concentrated in the Midwest, Northeast and North macro-regions. The predominant victim was the young, brown man with low education level. Work-related accidents were ignored 57-70% of notifications. The increase in the circulating fleet was strongly related to the increase in death rates among motorcyclists in Brazil (0.981; p &lt;0.001). Conclusion This is a growing problem of public health, which mainly affects young people in social vulnerability. The massification of the fleet and the increase of mortality refer to the responsibility of the State to establish intersectional actions in order to reduce vulnerability of motorcyclists.

title: Population dynamics of a freshwater amphipod from South America (Crustacea, Amphipoda, Hyalellidae)

description: Abstract This study aimed to characterize the population dynamics of Hyalella bonariensis Bond-Buckup, Araujo & Santos, 2008 from headwater spring in a rural area of state of Rio Grande do Sul, Brazil. Four samples were collected in August (winter) and October (spring) of 2012 and January (summer) and April (autumn) of 2013. Ovigerous females and precopula pairs were separated from other individual in the field. A total of 5,266 specimens were sampled, being 1,878 males, 2,073 females (including 240 ovigerous females) and 1,315 juveniles. The frequency distribution of size classes (measured as cephalothorax length, CL) was polymodal and bimodal in males and females, respectively. Males reach larger size than females. Sexual maturity of males and females was estimated at 0.40 and 0.38 mm for CL, respectively. Total sex ratio favored females, and these were more frequent in intermediate size classes, while males were more frequent in larger size classes. Ovigerous females and couples were found in four seasons, but both were more abundant in winter. Juveniles were also found in all seasons, being more frequent in winter and spring. These results showed that this H. bonariensis population has similar dynamics to other species of Hyalella Smith, 1874 from Brazil, but present variations when compared to other freshwater amphipods.

title: Bioethical perspective of justice in clinical trials

description: Abstract Brazil has a welcoming setting for clinical trials, with national regulations and a well-developed and institutionalized monitoring system. Resolution 466/2012 of the Conselho Nacional de Saúde (Brazilian National Health Council) adopted the principle of justice as a fundamental requirement for ethics in research. The aim of the present study was to investigate the bioethical meanings attributed to this principle in clinical trials with drugs in the country. The study was conducted through a thorough literature review, which was performed in two phases: understanding trial regulations and systematically researching the issue. Discussions regarding the principle of justice vary greatly when addressing the different stages of trials. The authors’ perceptions were organized into three categories, which are interchangeable to a certain degree. Empirical studies and discussions must be conducted in relation to the application of this principle during the ethical analysis of clinical trials, while also addressing the adequacy and effectiveness of this principle in reducing social injustices in the health sector.

title: Body image satisfaction, sociodemographic, functional and clinical aspects of community-dwelling older adults

description: Abstract Body image, according to the definition by Ledoux et al.(1) is “the systematic, cognitive, affective, conscious, and unconscious representation that people have concerning their bodies during their biological development and throughout their social relationships”. Objective: To determine the prevalence of body image satisfaction (BIS) and its relationship with sociodemographic, functional and clinical aspects in older adults. Methods: A cross-sectional, analytical and prospective study of a random sample of older adults from all health districts of Porto Alegre (30 health units) was conducted. The following aspects were studied: sociodemographic data (sex, age, marital status and education), BIS (Stunkard’s scale), functional tests (30 seconds Sit/Stand Test, time to walk 10m, Handgrip Strength - HGS), physical activity (Minnesota Questionnaire) and cognition (Mini-Mental State Examination). Results: Most of the 532 participants were dissatisfied with their body image (92.5%), particularly the women (71.7%). After Binary Logistic Regression (6 steps), BIS predictors were: high scores for the Sit/Stand (OR: 1.13; p=0.013), higher HGS (OR: 1.06; p=0.049), shorter time engaged in physical activity (OR: 0.77; p&lt;0.001). Conclusion: The prevalence of BIS was low and most of the variables analyzed bore no relation to BIS. Notwithstanding, a relationship was found with greater HGS, higher Sit/Stand score and less time engaged in physical activity. Given the scarcity of studies on this subject, our study furthers the knowledge on how body image affects this population group.

title: From beyond the Kwango - Tracing the Linguistic Origins of Slaves Leaving Angola, 1811-1848

description: Abstract: The Kwango River has long been viewed as the limit of the transatlantic traders' access to the main sources of slaves in the interior of Angola, the principal region of slave embarkation to the Americas. However, no estimates of the size and distribution of this huge migration exist. This article examines records of liberated Africans from Cuba and Sierra Leone available on the African Origins Portal to estimate how many slaves came from that particular region in the nineteenth century as well as their ethnolinguistic distribution. It shows that about 21 percent of the slaves leaving Angola in that period came from beyond the Kwango, with the majority coming from among the Luba, Kanyok, and Swahili speaking peoples. The article also analyzes the causes of this migration, which helped shape the African Diaspora to the Americas, especially to Brazil and Cuba.

title: Prevalence of metabolic syndrome among workers from the Company of Generation and Distribution of Energy in Rio de Janeiro, Brazil

description: Little is known about the prevalence of metabolic syndrome in the World’s working force. We examined the prevalence of such disease in the Company of Generation and Distribution of Energy in Rio de Janeiro city, Brazil.METHODS: A cross-sectional study was designed to analyze data from employees submitted to the annual company medical check-up in 2008. Medical charts were reviewed for collection of clinical and laboratorial information.RESULTS: The total prevalence of metabolic syndrome was 48.6% (95%CI 46.0-51.2). It increased with age and reached 58.7% (95%CI 56.1-61.3) in employees older than 60 years. The age- adjusted prevalence was 38.2% (95%CI 35.7-40.7). Increased waist circumference was the most prevalent component of the syndrome (94.2%; 95%CI 92.1-95.7), followed by high blood pressure (69.3%; 95%CI 65.7-72.7). In a multivariate analysis age, sedentary lifestyle and level of uric acid were significantly associated with the metabolic syndrome.CONCLUSION: Metabolic syndrome is highly prevalent in the studied working population in Rio de Janeiro. Our study will help delineating key risk factors for the development of metabolic syndrome in Brazil and may help the creation of new preventive public health policies.

title: Leprosy after release from treatment in the Brazilian Unified Health System: aspects for access in the Northeast region

description: Universal access to health services represents a complex process of inter-relationships between users and health services. In a broader sense it includes economic, technical, political and symbolic aspects. For neglected diseases such as leprosy, this is a major challenge. This cross-sectional study aims to characterize access to health care services for people affected by leprosy after release from treatment in the cities of Sobral and Fortaleza. The study included a representative sample 10% of those concluding treatment from 2003 to 2005 (304 cases). Participants were characterized regarding socio demographic and clinical variables and access to health services after release from treatment. The study population was mostly male (58%), physical disabilities (34%) and with leprosy reactions (37%). The biomedical approach of leprosy reactions contemplated in large part to search for and supply of care in this period. The access to care after discharge was particularly weak in rehabilitative interventions such as surgery and psychological attention. We identified important gaps in the operationalization of attention to people affected after release from treatment in both cities. The date also shows the negligence of leprosy as a chronic condition and the resulting difficulties regarding on integrated distance to the comprehensive approach to people with leprosy after release from treatment in the Unified Health System (SUS).

title: Use of HAS-BLED Score in an Anticoagulation Outpatient Clinic of a Tertiary Hospital

description: Abstract Background: HAS-BLED score was developed to assess 1-year major bleeding risk in patients anticoagulated with vitamin K antagonists (VKA) due to atrial fibrillation (AF). Objective: Of this study was to assess the ability of HAS-BLED score and its components to predict major bleeding in patients treated in an anticoagulation outpatient clinic of a tertiary hospital. Methods: A retrospective cohort study on AF patients treated with VKA was conducted. Logistic regression analysis was performed to evaluate the ability of individual score components to predict major bleeding. The significance level adopted in all tests was 5%. Results: We studied 263 patients with a mean age of 71.1 ± 10.5 years over a period of 237.6 patients-year. Median HAS-BLED score was 2 (1-3). The overall incidence of major bleeding was 5.7%, and it was higher among high-risk HAS-BLED score patients than in low risk patients (9.6 vs. 3.1%; p = 0.052). Area under the ROC curve was 0.70 (p = 0.01). Cut-off point ≥ 3 showed sensibility of 66.7%, specificity of 62.1%, positive predictive value of 9.6% and negative predictive value of 96.9%. Major bleeding-free survival was lower in high-risk group (p = 0.017). In multivariate analysis, concurrent antiplatelet use was the only independent predictor of major bleeding among score components (OR 5.13, 95%CI: 1.55-17.0; p = 0.007). Conclusion: HAS-BLED score was able to predict major bleeding in this cohort of AF patients. Among score components, special attention should be given for concomitant antiplatelet use, which was independently associated to this outcome. Antiplatelets in AF patients under VKA anticoagulation should be used in selected patients with favorable risk-benefit assessment.

title: Incorporation of disinfectants for obtaining dental stone: microbiological and dimensional evaluation

description: AIM: To assess dimensional change and antimicrobial activity of disinfectants substances incorporated during the dental stone manipulation. MATERIAL AND METHOD: In vivo - microorganisms were collected in alginate molds of 30 volunteers inoculated on BHI agar and incubated at 37 °C for 24 hours. The molds were cast with type IV gypsum, manipulated with saline (G1), 1% sodium hypochlorite (G2) and 4% chlorhexidine (G3), replacing the water. After setting of plaster with 1 hour two collections on models were made. After 24 hours, the readings were performed. The Kruskal-Wallis and Wilcoxon tests with confidence interval of 99% and 95% respectively were used. In vitro - Müeller Hinton agar petri dishes were inoculated with S. mutans (ATCC25175), S. sanguis (ATCC10556) and E. faecalis (ATCC29212), over which were placed steel rings filled with the same substances of the in vivo study. After deposition of gypsum and incubation, halos were measured with a digital caliper and data were submitted to ANOVA and Tukey's test with confidence interval of 95%. Dimensional Change - With a metallic matrix and a perfectly adapted tray, the insertion axis and force used for moulding and obtain 30 specimens in type IV gypsum were standardized, following the same distribution of the study groups in vivo. The specimens were measured by Image Pro Plus software and data were submitted to ANOVA and Tukey's test with confidence interval of 95%. RESULT: Data from the in vivo study demonstrated a significant difference between the mold and each model (p&lt;0.001). In the Wilcoxon test there was no significant difference between groups of models. At the in vitro test, G2 showed greater inhibition zones in all micro-organisms tested compared to G3, but with respect to dimensional changes, there was a significant difference between solutions and metallic standard, where G3 caused less change than G2. CONCLUSION: Chlorhexidine 4% showed to be the most suitable disinfectant.

title: EXOTIC ARBUSCULAR MYCORRHIZAL FUNGI AND NATIVE DARK SEPTATE ENDOPHYTES ON THE INITIAL GROWTH OF Paspalum millegrana GRASS

description: ABSTRACT Arbuscular mycorrhizal fungi (AMF) and dark septate endophytic fungi (DSE) promote increase in plant biomass, depending on the soil and climate conditions and the interactions with the host plant. The objective of this study was to evaluate the interaction of exotic arbuscular mycorrhizal fungi and native DSE fungi on the initial growth of P. millegrana. A completely randomized experimental design comprising the Paspallum millegrana cutilvar with the following treatments: control - without AMF, and three exotic AMF isolates (UFLA351 - Rhizoglomus clarum, UFLA372 - Claroideoglomus etunicatum and UFLA401 - Acaulospora morrowiae), with four replications each. P. millegrana grass was colonized by exotic AMF by R. clarum (UFLA351, 11.9%), C. etunicatum (UFLA372, 39.6%), and A. morrowiae (UFLA401, 51.2%). P. millegrana was also colonized by native DSE fungi, but these did not interfere with the colonization by exotic AMF and plant development. P. millegrana is responsive to the inoculation of UFLAs isolates of exotic AMF, which may contribute to the grass growth and survival under field conditions. The process of surface disinfestation of seeds does not eliminate endophytic microorganisms, whose presence may influence plant colonization by AMF, as well as development of the host plant.
