The Case Against Non-Compliance with the Fundamental Principle concerning Anencephaly, under review by the Brazilian Supreme Court, is a milestone in the debate on abortion in Latin America. Since the currently prevailing version of the Brazilian Penal Code was enacted in 1940, there has been fierce resistance to any change in the country's abortion policy. This article discusses the arguments and political strategies used in the anencephaly suit brought before the Supreme Court, particularly the ethical and legal position that interruption of pregnancy in cases of anencephaly does not constitute abortion, but should be considered a therapeutic anticipation of delivery.

Roberts, Teresa Eliot

2007-01-01

This ethnographic examination of Brazilian immigrant perspectives regarding healthcare in the U.S. included participant observation and interviews with 42 Brazilian transnationals. Data were analyzed using Agar's approach. Findings show that Brazilians accessed allopathic care only as a last resort after self-treatment strategies failed, that they tended to feel that diagnostic testing, referrals, and symptom-relieving prescriptions were imperative to good care, and that they expected more personal warmth, continuity of care, and more affectionate verbal and nonverbal cues than their U.S. clinicians provided. Recommendations to improve quality of healthcare to Brazilian transnationals in the USA are discussed.

To estimate the coverage of the reporting of cases of HIV-infected pregnant women, to estimate the increase in the coverage of the reporting with the routine search of data in other Brazilian health information systems, and to identify missed opportunities for identification of HIV-infected pregnant women in Brazilian maternity hospitals. This is a descriptive study on the linkage of Brazilian databases with primary data from the "Nascer no Brasil" study and secondary database collection from national health information systems. The "Nascer no Brasil" is a national-based study carried out in 2011-2012 with 23,894 pregnant women, which identified HIV-infected pregnant women using prenatal and medical records. We searched for cases of HIV-infected pregnant women identified in the "Nascer no Brasil" study in the Information System of Notifiable Diseases, the Control System for Laboratory Tests of the National CD4+/CD8+ Lymphocyte Count and HIV Viral Load Network, and the Logistics Control System for Medications. We used the OpenRecLink software for the linkage of databases. We estimated the notification coverage, with the respective confidence interval, of the evaluated Brazilian health information systems. We estimated the coverage of the reporting of HIV-infected pregnant women in the Information System of Notifiable Diseases as 57.1% (95%CI 42.9-70.2), and we located 89.3% of the HIV-infected pregnant women (95%CI 81.2-94.2) in some of the Brazilian health information systems researched. The search in other national health information systems would result in an increase of 57.1% of the reported cases. We identified no missed opportunities for the diagnosis of HIV+ in pregnant women in the maternity hospitals evaluated by the "Nascer no Brasil" study. The routine search for information in other Brazilian health information systems, a procedure carried out by the Ministry of Health for cases of AIDS in adults and children, should be adopted for cases of HIV in

Suspicion of Brazilian spotted fever (BSF) should occur in endemic regions upon surveillance of the acute febrile icteric hemorrhagic syndrome (AFIHS). However, limitations associated with currently available laboratory tests pose a challenge to early diagnosis, especially in fatal cases. Two real-time PCR (qPCR) protocols were evaluated to diagnose BSF in 110 fatal AFIHS cases, collected in BSF-endemic regions in 2009-2010. Of these, 24 were positive and 86 negative by indirect immunofluorescence (IFA) assay (cut-off IgG and/or IgM ≥ 128). DNA from these samples was used in the qPCR protocols: one to detect Rickettsia spp. (citrate synthase gene) and another to determine spotted fever group (SFG) Rickettsia species (OmpA gene). Of the 24 IFA-positive samples, 5 (21%) were positive for OmpA and 9 (38%) for citrate synthase. In the IFA-negative group (n=86), OmpA and citrate synthase were positive in 23 (27%) and 27 (31%), respectively. These results showed that the 2 qPCR protocols were about twice as sensitive as the IFA test alone (93% concordance). In conclusion, qPCR is a sensitive method for the diagnosis of fatal BSF cases and should be considered for routine surveillance of AFIHS in places like Brazil, where spotted fever-related lethality is high and other endemic diseases like dengue and leptospirosis can mislead diagnosis.

Luso-Brazilian Enlightenment and the circulation of Caribbean slavery-related knowledge: the establishment of the Brazilian coffee culture from a comparative perspective.

PubMed

Marquese, Rafael de Bivar

2009-01-01

The generation of enlightened Luso-Brazilians saw Caribbean slavery agriculture as the model to be emulated in Portuguese America. To do so, at the turn of the eighteenth to the nineteenth centuries, they translated and published some texts originally elaborated in the Antilles. In this reformist environment, the coffee culture occupied a place of prominence. To understand the role of this knowledge in establishing the Brazilian coffee culture, the Brazilian case is compared with the Cuban. The intent is to demonstrate that in the Spanish colony, the productive coffee plan of Santo Domingo was implanted, while in Brazil a plan was created, supported by new standards of agricultural management that were founded on local knowledge.

This review of original reports on metabolic and infectious diseases that were recently published in Brazilian journals is designed to inform the readership of CLINICS about their content. I conducted a search in PubMed for original research articles (clinical or basic research) recently published (2008-2009) by Brazilian medical and biological periodicals. Papers on metabolic pathologies were retrieved by searching for appropriate keywords such as metabolic syndrome and obesity. Papers on infectious disease were obtained by entering 15 different keywords for the most commonly occurring pathologies. Review articles, editorials, letters to the editor, and case reports were manually excluded. Selected titles were then categorized into appropriate sub-categories. This search produced a total of 123 articles, which filtered down to 72 articles after eliminating editorials, review articles, letters to the Editor and case reports. Reviewed periodicals were Arquivos Brasileiros de Cardiologia, Arquivos Brasileiros de Endocrinologia e Metabologia, Brazilian Journal of Biological and Medical Research, Brazilian Journal of Infectious Diseases, Jornal de Pediatria, Jornal de Pneumologia, Revista da Associação Médica Brasileira, Revista da Escola de Enfermagem da Universidade de São Paulo, and São Paulo Medical Journal.

The political contradictions of incremental innovation: lessons from pharmaceutical patent examination in Brazil.

PubMed

Shadlen, Kenneth C

2011-01-01

Neodevelopmental patent regimes aim to facilitate local actors’ access to knowledge and also encourage incremental innovations. The case of pharmaceutical patent examination in Brazil illustrates political contradictions between these objectives. Brazil’s patent law includes the Ministry of Health in the examination of pharmaceutical patent applications. Though widely celebrated as a health-oriented policy, the Brazilian experience has become fraught with tensions and subject to decreasing levels of both stability and enforcement. I show how one pillar of the neodevelopmental regime, the array of initiatives to encourage incremental innovations, has fostered the acquisition of innovative capabilities in the Brazilian pharmaceutical sector, and how these new capabilities have altered actors’ policy preferences and thus contributed to the erosion of the coalition in support of the other pillar of the neodevelopmental regime, the health-oriented approach to examining pharmaceutical patents. The analysis of capability-derived preference formation points to an endogenous process of coalitional change.

Resource Mobilization for Health Advocacy: Afro-Brazilian Religious Organizations and HIV Prevention and Control

2010-01-01

Brazil’s national response to AIDS has been tied to the ability to mobilize resources from the World Bank, the World Health Organization, and a variety of donor agencies. The combination of favorable political economic opportunities and the bottom-up demands from civil society make Brazil a particularly interesting case. Despite the stabilization of the AIDS epidemic within the general Brazilian population, it continues to grow in pockets of poverty, especially among women and blacks. We use resource mobilization theories to examine the role of Afro-Brazilian religious organizations in reaching these marginalized populations. From December 2006 through November 2008, we conducted ethnographic research, including participant observation and oral histories with religious leaders (N=18), officials from the National AIDS Program (N=12), public health workers from Rio de Janeiro (N=5), and non-governmental organization (NGO) activists who have worked with Afro-Brazilian religions (N=5). The mobilization of resources from international donors, political opportunities (i.e., decentralization of the National AIDS Program), and cultural framings enabled local Afro-Brazilian religious groups to forge a national network. On the micro-level, in Rio de Janeiro, we observed how macro-level structures led to the proliferation of capacity-building and peer educator projects among these religious groups. We found that beyond funding assistance, the interrelation of religious ideologies, leadership, and networks linked to HIV can affect mobilization. PMID:20542364

2013-01-01

Although gender is often acknowledged as a determinant of health, measuring its components, other than biological sex, is uncommon. The Bem Sex Role Inventory (BSRI) quantifies self-attribution of traits, indicative of gender roles. The BSRI has been used with participants across cultures and countries, but rarely in an older population in Brazil, as we have done in this study. Our primary objective was to determine whether the BSRI-12 can be used to explore gender in an older Brazilian population. The BSRI was completed by volunteer participants, all community dwelling adults aged 65+ living in Natal, Brazil. Exploratory factor analysis was performed, followed by a varimax rotation (orthogonal solution) for iteration to examine the underlying gender roles of feminine, masculine, androgynous and undifferentiated, and to validate the BSRI in older adults in Brazil. The 278 participants, (80 men, 198 women) were 65-99 years old (average 73.6 for men, 74.7 for women). Age difference between sexes was not significant (p = 0.22). A 12 item version of the BSRI (BSRI-12) previously validated among Spanish seniors was used and showed validity with 5 BSRI-12 items (Cronbach=0.66) loading as feminine, 6 items (Cronbach=0.51) loading onto masculine roles and neither overlapping with the category of biological sex of respondent. Although the BSRI-12 appears to be a valid indicator of gender among elderly Brazilians, the gender role status identified with the BSRI-12 was not correlated with being male or female.

Publication in a Brazilian journal by Brazilian scientists whose papers have international impact.

PubMed

Meneghini, R

2010-09-01

Nine Brazilian scientists with an outstanding profile of international publications were invited to publish an original article in the same issue of a Brazilian Journal (Anais da Academia Brasileira de Ciências). The objective was to measure the impact of the papers on the number of citations to the articles, the assumption being that these authors would carry their international prestige to the Brazilian periodical. In a 2-year period there was a larger number of citations of these articles compared to others published in the same journal. Nevertheless, the number of citations in Brazilian journals did not equal the number of citations obtained by the other papers by the same authors in their international publications within the same 2-year period. The reasons for this difference in the number of citations could be either that less significant invited articles were submitted or that it was due to the intrinsic lack of visibility of the Brazilian journals, but this could not be fully determined with the present data. Also relevant was a comparison between the citations of Brazilian journals and the publication in Brazilian journals by these selected authors. A clear imbalance due to a remarkable under-citation of Brazilian authors by authors publishing in Brazilian journals raises the possibility that psychological factors may affect the decision of citing Brazilian journals.

To estimate the prevalence and describe the distribution of trachoma among schoolchildren in Brazilian municipalities. Cross-sectional study, using cluster sampling, of the schoolchildren population of the Brazilian municipalities with Human Development Index - Municipal lower than the national average. This trachoma prevalence survey was conducted by the Ministry of Health, in the period 2002-2007. There were 119,531 schoolchildren selected from 2,270 schools located in 1,156 municipalities. The selected schoolchildren underwent an external ocular examination, with a magnifying glass (2.5X), to detect clinical signs of trachoma according to the WHO criteria. The prevalence of trachoma, by state and national level, and their respective 95% confidence intervals were estimated. Chi-square and Chi-square for trends tests were used to compare categorical variables. There were 6,030 cases of trachoma detected, resulting in a prevalence of 5.0% (95%CI 4.5;5.4). There was no significant difference between the sexes. The prevalence of trachoma was 8.2% among children under 5 years of age, decreasing among higher age groups (p < 0.01). There was a significant difference in prevalence between urban and rural areas, 4.3% versus 6.2% respectively (p < 0.01). Cases were detected in 901 municipalities (77.7% of the sample), in all regions of the country. In 36.8% of the selected municipalities, the prevalence was higher than 5%. The study shows that trachoma is a significant public health problem in Brazil, contradicting the belief that the disease had been controlled in the country. The survey provides a baseline for evaluating planned interventions aimed at achieving the goal of global certification of elimination of trachoma as a cause of blindness in Brazil by 2020.

Tuberculosis caused by Mycobacterium bovis is an important worldwide zoonosis and has been reported to cause clinical disease in several animal species, including captive wildlife. This report describes a case of M. bovis infection in a European bison from a Brazilian zoo and compiles a number of literature reports that raise concern regarding tuberculosis among captive wildlife in Brazil. A 13 year-old captive-born male bison (Bison bonasus) from a Brazilian zoo began presenting weight loss, diarrhea and respiratory symptoms, which inevitably led to his death. At the animal's necropsy, inspection of the thoracic and abdominal cavities revealed multiple enlarged lymph nodes, ranging from 4 to 10 cm, and pulmonary nodules containing caseous masses with firm white materials consistent with mineralization. Histopathology findings showed a significant amount of acid-alcohol resistant bacilli compatible with Mycobacterium spp. Specimens from lymph nodes and lungs were cultured on Petragnani and Stonebrink media, and specific PCR assays of the bacterial isolate identified it as M. bovis. The European bison reported herein died from a severe form of disseminated tuberculosis caused by M. bovis. A review of the available literature indicates possible widespread occurrence of clinical disease caused by M. bovis or M. tuberculosis affecting multiple animal species in Brazilian wildlife-related institutions. These likely underestimated numbers raise concern regarding the control of the disease in captive animal populations from Brazil.

The recent advent of the commercial launch and re- entry activities, for promoting the expansion of human access to space for tourism and hypersonic travel, in the already complex ambience of the global space activities, brought additional difficulties over the development of a harmonized framework of international safety rules. In the present work, with the purpose of providing some complementary elements for global safety rule development, the certification-related activities conducted in the Brazilian space program are depicted and discussed, focusing mainly on the criterion for certification basis compilation. The results suggest that the composition of a certification basis with the preferential use of internationally-recognized standards, as is the case of ISO standards, can be a first step toward the development of an international safety regulation for commercial space activities.

Aechmea subgenus Ortgiesia comprises ca. 20 species distributed in Brazil, Argentina, Paraguay, and Uruguay, with a center of diversity in the Brazilian Atlantic rainforest. We examined interspecific relationships of Ortgiesia based on Amplified Fragment Length Polymorphisms (AFLP). Ninety-six accessions belonging to 14 species of Ortgiesia were sampled, and genotyped with 11 AFLP primer combinations. The neighbor joining (NJ) tree depicted two main genetic groups within Aechmea subgenus Ortgiesia, and four subgroups. The NJ tree showed short internal branches, indicating an overall shallow genetic divergence among Ortgiesia species as expected for the recently radiated subfamily Bromelioideae. Our results suggest that hybridization and/or incomplete lineage sorting may have hampered the reconstruction of interspecific relationships in Aechmea subgenus Ortgiesia. The mapping of petal color (yellow, blue, pink, or white), inflorescence type (simple or compound), and inflorescence shape (ellipsoid, subcylindric, cylindric, or pyramidal) against the NJ tree indicated that these characters are of limited taxonomic use in Aechmea subgenus Ortgiesia due to homoplasy. An analysis of the current distribution of Ortgiesia identified the southern region of the Brazilian Atlantic rainforest, between latitudes of 26° and 27°S, as the center of diversity for the subgenus.

Background Social determinants can affect the transmission of leprosy and its progression to disease. Not much is known about the effectiveness of welfare and primary health care policies on the reduction of leprosy occurrence. The aim of this study is to evaluate the impact of the Brazilian cash transfer (Bolsa Família Program-BFP) and primary health care (Family Health Program-FHP) programs on new case detection rate of leprosy. Methodology/Principal Findings We conducted the study with a mixed ecological design, a combination of an ecological multiple-group and time-trend design in the period 2004–2011 with the Brazilian municipalities as unit of analysis. The main independent variables were the BFP and FHP coverage at the municipal level and the outcome was new case detection rate of leprosy. Leprosy new cases, BFP and FHP coverage, population and other relevant socio-demographic covariates were obtained from national databases. We used fixed-effects negative binomial models for panel data adjusted for relevant socio-demographic covariates. A total of 1,358 municipalities were included in the analysis. In the studied period, while the municipal coverage of BFP and FHP increased, the new case detection rate of leprosy decreased. Leprosy new case detection rate was significantly reduced in municipalities with consolidated BFP coverage (Risk Ratio 0.79; 95% CI  = 0.74–0.83) and significantly increased in municipalities with FHP coverage in the medium (72–95%) (Risk Ratio 1.05; 95% CI  = 1.02–1.09) and higher coverage tertiles (>95%) (Risk Ratio 1.12; 95% CI  = 1.08–1.17). Conclusions At the same time the Family Health Program had been effective in increasing the new case detection rate of leprosy in Brazil, the Bolsa Família Program was associated with a reduction of the new case detection rate of leprosy that we propose reflects a reduction in leprosy incidence.

This study assessed the epidemiological characteristics and management of the permanent teeth avulsion cases attended in a Brazilian dental trauma service from December 2005 to August 2016. A retrospective study was conducted of case records of 93 patients involving 139 avulsed teeth. Data included sex, age, trauma etiology, location of the accident, number and position of avulsed teeth, and presence and type of associated traumatic lesions. Management of the avulsed teeth was addressed as: time elapsed until teeth were retrieved from the accident's location; teeth's cleaning method and storage media; time elapsed until seeking treatment and replantation. The majority of the patients were children from 6-10 (31.2%) and 11-15 years old (26.9%). Male patients were more affected than female. Bicycle accident was the main etiological factor (31.2%). In 56 (60.2%) cases, traumatic lesions to neighboring teeth were present. In 55 (59.1%) cases, lesions to adjacent soft tissues were reported. In 82 (88.2%) cases, patients requested treatment at the same day of the accident. Sixty-four teeth (46.0%) were immediately retrieved and 28 (20.1%) were not found. Forty-two teeth (30.2%) were kept dry. Only one tooth (0.7%) was immediately replanted at the accident's site, while 51 teeth (36.7%) were not replanted. Numerous avulsed teeth were inappropriately managed and immediate replantation was not frequent. Public policies must be created to raise awareness towards the particularities of avulsion cases.

Public counselling: Brazilian Pentecostal intimate performances among urban women in Mozambique.

van de Kamp, Linda

2013-01-01

Analysing the public character of Brazilian Pentecostal counselling sessions in urban Mozambique, this paper aims to examine the configurations of exposure through which counselling acquires and produces sociocultural forms of intimacy. During 'therapy of love' sessions held by the Brazilian Universal Church of the Kingdom of God, strict bodily acts need to be performed publicly to authorise love. Drawing on the notion of religious habitus, the paper focuses on how the performativity of Brazilian Pentecostal counselling practices responds to and shapes a public culture of love and intimacy among upwardly mobile women in urban Mozambique, and how the performative scripts converts carry out during therapy result in ambiguous relationships.

Quotations in Brazilian journals are mainly obtained from national articles (articles from Brazilian journals); thus, it is essential to determine how frequently these articles reference Brazilian journals. This study sought to verify how frequently national papers are cited in the references of three Brazilian physical therapy journals. All references for articles published in Fisioterapia em Movimento, Fisioterapia e Pesquisa and Revista Brasileira de Fisioterapia between 2010 and 2012 were evaluated. In particular, the numbers of national articles and international articles (articles from international journals) cited in these references were determined. A total of 13,009 references cited by 456 articles were analyzed, and 2,924 (22.47%) of the cited works were national articles. There were no significant differences among the three examined years. A total of 36 (7.89%) articles did not cite national articles, whereas 65 (13.25%) articles cited more national articles than international articles. On average, 22.47% of the works cited by the evaluated articles were national articles. No significant differences were detected among the three analyzed years.

The quest for recognition: Brazilian immigrants in the United States.

PubMed

Zubaran, Carlos

2008-12-01

'Hispanic' and 'Latino' are imprecise umbrella terms often used in the United States to designate nationals from Central and South America. The labelling of Brazilians in this manner generates inaccurate demographic information, including a significant undercount of the migrant population. Research data indicates that Brazilians object to being designated Hispanics, since Brazilians speak Portuguese and have no Spanish heritage. The labelling of ethnic groups has been criticized as a stereotypical and racist system, which primarily responds to non-scientific demands. This commentary appeals for reform in the way researchers and institutions refer to minority citizens as well as for continued research to investigate racism and ethnic prejudice. The development of new approaches and methodologies to examine social networks, migration and the geographic concentration of poverty is advocated.

Anthropophagy: a singular concept to understand Brazilian culture and psychology as specific knowledge.

PubMed

Ferreira, Arthur Arruda Leal

2015-11-01

The aim of this work is to present the singularity of the concept of anthropophagy in Brazilian culture. This article examines its use in the Modernist Movement of the 1920s and explores the possibilities it creates for thinking about Brazilian culture in nonidentitarian terms. We then use the concept of anthropophagy in a broader, practical sense to understand psychology as a kind of anthropophagical knowledge. We do so because in many ways the discipline of psychology is similar to Brazilian culture in its plurality and complexity. (c) 2015 APA, all rights reserved).

Multinationals, state-owned corporations, and the transformation of imperialism: a Brazilian case study

DOE Office of Scientific and Technical Information (OSTI.GOV)

Evans, P.

1977-10-01

The Brazilian petrochemical industry is used as a case study in cooperation of state-owned and multinational corporations in bringing capitalism into the Third World. The petrochemical industry was chosen because it entails enormous transfers of capital investment and technology and the development of internal industrialization. Active participation by the host state, while it modifies the capitalization process, also is seen to provide a mutually beneficial partnership. A chronological account is given of the process by which Brazil evolved a system for encouraging multinationals to bring basic industries while participating directly in production. Multinationals have found that state-owned corporations do notmore » destroy capitalism, while the state-owned corporations have adapted to a profit orientation. A new ruling class has emerged in the process to provide technical and managerial skills. A disappointing social record developed at the same time and indicates the capitalization process was not able to provide the expected social benefits. (DCK)« less

The Brazilian Public Health in Contemporary Capitalism.

Junqueira, Virgínia; Mendes, Áquilas N

2018-01-01

This article examines some political and economic facts that led to an intensification of austerity measures by the Brazilian government, including ones against the Unified Health System (SUS) and its progressive dismantling. In a country where fundamental human rights were never fully respected, nowadays social and labor rights are under severe attacks. The deepening of the capital crisis and the rise of interest-bearing capital dominance have been causing unemployment, social insecurity growth, and resulting public fund appropriation by the private capital. The Brazilian governments in the 1990s and 2000s have implemented deeper cuts in social policy expenditure, freezing security benefits, privatizing services, and prioritizing the payment of public debt interests. The right wing's project involves the demoralization of not only the Workers' Party but also the left as a whole, so that the adoption of austerity measures could be achieved without popular resistance. It is the duty of the Brazilian left wing to denounce such a project and to provoke firm initiatives to rebuild its bonds with the working class.

Freshwater stingray injuries are a common problem in the Brazilian Amazon, affecting mostly riverine and indigenous populations. These injuries cause severe local and regional pain, swelling and erythema, as well as complications, such as local necrosis and bacterial infection. Herein, we report a case of bacterial infection and hallux necrosis, after a freshwater stingray injury in the Brazilian Amazon, which eventually required amputation. Different antimicrobial regimens were administered at different stages of the disease; however, avoiding amputation through effective treatment was not achieved.

Brazilian scientists have been contributing to the protozoology field for more than 100 years with important discoveries of new species such as Trypanosoma cruzi and Leishmania spp. In this work, we used a Brazilian thesis database (Coordination for the Improvement of Higher Education Personnel) covering the period from 1987-2011 to identify researchers who contributed substantially to protozoology. We selected 248 advisors by filtering to obtain researchers who supervised at least 10 theses. Based on a computational analysis of the thesis databases, we found students who were supervised by these scientists. A computational procedure was developed to determine the advisors' scientific ancestors using the Lattes Platform. These analyses provided a list of 1,997 researchers who were inspected through Lattes CV examination and allowed the identification of the pioneers of Brazilian protozoology. Moreover, we investigated the areas in which researchers who earned PhDs in protozoology are now working. We found that 68.4% of them are still in protozoology, while 16.7% have migrated to other fields. We observed that support for protozoology by national or international agencies is clearly correlated with the increase of scientists in the field. Finally, we described the academic genealogy of Brazilian protozoology by formalising the "forest" of Brazilian scientists involved in the study of protozoa and their vectors over the past century.

[The illegal market for gender-related drugs as portrayed in the Brazilian news media: the case of misoprostol and women].

PubMed

Diniz, Debora; Castro, Rosana

2011-01-01

This article analyzes how the Brazilian news media covers the illegal market for misoprostol, the main drug used to induce abortion. A total of 1,429 news stories were retrieved from 220 print and electronic media channels from 2004 to 2009. The analysis included 524 stories from 62 regional and national newspapers. Misoprostol appeared repeatedly in the news, but was usually approached from a criminal perspective, unlike abortion as a whole, which the Brazilian media routinely covers as a religious, political, and public health issue. Misoprostol is part of the illegal gender-related drug market, along with drugs for weight loss and erectile dysfunction and anabolic steroids. Sixty-four (12%) of the news stories told life histories of women who had aborted with misoprostol. The women's ages ranged from 13 to 46 years, and socioeconomic status was associated with different experiences with abortion. Three characters appeared in the women's abortion itineraries: girlfriends (confidantes), go-betweens, and physicians. Stories of late-stage abortion are confused with the criminal characterization of infanticide and provide the extreme cases in the media's narrative on abortion.

The article contextualizes the emergence of an international policy for the Brazilian Unified Health System as the common agenda of the Pan American Health Organization (PAHO) and the Brazilian Ministry of Health. For this purpose, two contextual axes were explored throughout the work. The first discusses the explicit relationship between the development-cooperation-health triad from an international perspective. The second examines the recent evolution of Brazilian foreign policy, particularly with respect to the role it is playing in South-South cooperation on health matters. The contextual framework that defines Brazilian international cooperation with PAHO is emphasized, above all with regard to the implementation of a specific cooperation agreement. The article concludes that this agreement, within the framework of South-South cooperation, is one of the principal institutional mechanisms established to bring about technical cooperation in health in the current setting.

Brazil is a country of continental dimensions with a large heterogeneity of climates and massive mixing of the population. Almost the entire national territory is located between the Equator and the Tropic of Capricorn, and the Earth axial tilt to the south certainly makes Brazil one of the countries of the world with greater extent of land in proximity to the sun. The Brazilian coastline, where most of its population lives, is more than 8,500 km long. Due to geographic characteristics and cultural trends, Brazilians are among the peoples with the highest annual exposure to the sun. Epidemiological data show a continuing increase in the incidence of non-melanoma and melanoma skin cancers. Photoprotection can be understood as a set of measures aimed at reducing sun exposure and at preventing the development of acute and chronic actinic damage. Due to the peculiarities of Brazilian territory and culture, it would not be advisable to replicate the concepts of photoprotection from other developed countries, places with completely different climates and populations. Thus the Brazilian Society of Dermatology has developed the Brazilian Consensus on Photoprotection, the first official document on photoprotection developed in Brazil for Brazilians, with recommendations on matters involving photoprotection.

Paracoccidioidomycosis is a fungal infection endemic to South American countries that affects the lungs, skin, and mucosae. Reports from Japan are limited by a long-term resident in South America. Some cases are incorrectly diagnosed because of a refractory buccal ulcer that resembles a malignant tumor. This is a disease that may not be correctly examined if we cannot suspect by a case history. We report the case of a Brazilian man who had a buccal ulcer with lung involvement, which mimicked pharyngeal cancer.

Pharmacogenetics in the Brazilian Population

2010-01-01

Brazil is the fifth largest country in the world and its present population, in excess of 190;million, is highly heterogeneous, as a result of centuries of admixture between Amerindians, Europeans, and Sub-Saharan Africans. The estimated individual proportions of biogeographical ancestry vary widely and continuously among Brazilians: most individuals, irrespective of self-identification as White, Brown or Black – the major categories of the Brazilian Census “race/color” system – have significant degrees of European and African ancestry, while a sizeable number display also Amerindian ancestry. These features have important pharmacogenetic (PGx) implications: first, extrapolation of PGx data from relatively well-defined ethnic groups is clearly not applicable to the majority of Brazilians; second, the frequency distribution of polymorphisms in pharmacogenes (e.g., CYP3A5, CYP2C9, GSTM1, ABCB1, GSTM3, VKORC, etc) varies continuously among Brazilians and is not captured by race/color self-identification; third, the intrinsic heterogeneity of the Brazilian population must be acknowledged in the design and interpretation of PGx studies in order to avoid spurious conclusions based on improper matching of study cohorts. The peculiarities of PGx in Brazilians are illustrated with data for different therapeutic groups, such as anticoagulants, HIV protease inhibitors and non-steroidal antinflammatory drugs, and the challenges and advantages created by population admixture for the study and implementation of PGx are discussed. PGx data for Amerindian groups and Brazilian-born, first-generation Japanese are presented to illustrate the rich diversity of the Brazilian population. Finally, I introduce the reader to the Brazilian Pharmacogenetic Network or Refargen1, a nation-wide consortium of research groups, with the mission to provide leadership in PGx research and education in Brazil, with a population health impact.

Brazilian spotted fever (BSF) is caused by the bacterium Rickettsia rickettsii. Because of its high case-fatality rate and apparent increase in areas of transmission, it is considered to be the rickettsial illness of primary public health interest. Cases of this disease have historically occurred in Southeastern Brazil. This article reports the first fatal case of BSF in Southern Brazil. This case high lights the importance of BSF to be considered as a differential diagnosis for acute hemorrhagic fever in areas where cases of BSF may not be expected.

To describe treatment practices for ocular toxoplasmosis among members of the Brazilian Uveitis Society. An online questionnaire sent to specialists, between October 2014 and March 2015. Most respondents (67.9%) treat all active cases. Most specialists consider visual acuity <20/200 (88.2%), severe vitreous inflammation (94.1%), and ocular disease during acquired infection (88.2%) as absolute indications for treatment. Systemic steroids are associated with anti-toxoplasmic therapy in most cases by 50.9% of the respondents. For immunocompetent individuals, 57.4% of the respondents chose trimethoprim/sulfamethoxazole. Classical therapy (sulfadiazine/pyrimethamine) is preferred most for patients with central lesions (70.4%), immunosuppression (68.4%), acquired infection (70.4%), and atypical forms (74.1%). For patients with frequent relapses, 84.9% of the respondents preferred antibiotic prophylaxis. Treatment patterns of ocular toxoplasmosis are not uniform among Brazilian specialists. Most specialists treat all cases of active retinochoroiditis. Typical cases are more frequently treated with trimethoprim/sulfamethoxazole. However, classical therapy is the regimen of choice when lesions are considered more severe.

The aim of this article is to examine whether the diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), are able to differentiate between nonpathological religious possession and dissociative identity disorder (DID). We use the case study of an individual who leads an Afro-Brazilian religious group (Umbanda), focusing on her personal development and possession experiences from early childhood to the present, spanning a period of more than 40 years, and examine these data following DSM-5 criteria for DID (300.14). Her experiences of possession can be broken into 2 distinct stages. In the 1st stage (childhood and early adulthood), she displayed intrusive thoughts and a lack of control over possession states, which were associated with a heightened state of anxiety, loneliness, amnesia, and family conflict (meeting all 5 criteria for DID). In the 2nd stage (late 20s up to the present), she regularly experienced possession states but felt in control of their onset and found them religiously meaningful. In this 2nd stage, she only fulfilled 3 criteria for DID. We question the accuracy of diagnosing this individual with DID in her earlier life and suggest that the DSM-5 criteria fail to address the ambiguity of affect surrounding possession experiences (positive at the individual level, negative at the interpersonal level) and lack a clearer acknowledgment of the prevalence of possession and other unusual experiences in general populations.

OBJECTIVE: To determine the publication rate of orally-presented abstracts from the 2003 Urological Brazilian Meeting, as well as the factors determining this publication rate. MATERIALS AND METHODS: The publication rate of the 313 orally-presented abstracts at the 2003 Urological Brazilian Meeting was evaluated by scanning the Lilacs, Scielo and Medline databases. The time between presentation and publication, the state and country of the abstract, the research methodology (cross-sectional, case-control, retrospective case series, prospective case series or clinical trial), whether drugs were utilized and the topic of the study were all characterized. RESULTS: Thirty-nine percent of the abstracts were published after a median time of 14 months (range: 1 to 51 months). There were high publication rates for cross-sectional abstracts (75%), drug utilization studies (51.3%), clinical trials (50%) and prospective case series’ (48.1%). However, there was only a moderate statistical trend towards a higher publication rate in the prospective case series (p=0.07), while the retrospective case series’ showed statistically lower publication rates than the other groups (33.7%, p=0.04). Abstracts on laparoscopic surgery had the highest publication rate (61.9%, p=0.03) compared to others topics. In 57% of the unpublished abstracts, there was no interest in or attempt to publish, and rejection was responsible for the lack of publication of only 4% of the abstracts. CONCLUSION: The publication rate of the orally-presented abstracts from the 2003 Urological Brazilian Meeting was comparable to that of international congresses. The subsequent publication of presented abstracts and the selection of prospective studies with stronger evidence should be encouraged and may improve the scientific quality of the meeting.

The combination of PUBMED, SCieLO, open access and online searching has provided a significant increase in the visibility of Brazilian journals. This newly acquired international visibility has in turn resulted in the appearance of more original research reports in the Brazilian scientific press. This review is intended to highlight part of this work for the benefit of the readers of "Clinics." We searched through PUBMED for noteworthy articles published in Brazilian medical journals included in the Journal of Citation Reports of the Institute of Scientific Information to better expose them to our readership. The following journals were examined: "Arquivos Brasileiros de Cardiologia," "Arquivos Brasileiros de Endocrinologia e Metabologia," "Brazilian Journal of Medical and Biological Reviews," "Jornal Brasileiro de Pneumologia," "Jornal de Pediatria," "Revista Brasileira de Cirurgia Cardiovascular," "Revista da Associação Médica Brasileira," Revista da Escola de Enfermagem U.S.P." and "São Paulo Medical Journal." These journals publish original investigations in the field of cardiopulmonary disease. The search produced 71 references, which are briefly examined.

2018-06-01

Life expectancy (LE) refers to the number of years that an individual is expected to survive. Emphasis is frequently placed on the relationship between LE and the conditions under which a population lives, but fewer studies have investigated the relationship between stress factors associated with specific professions and their effects on LE. The aim of this study is to evaluate Brazilian neurosurgeons' life expectancies (BNLEs) and compare them with those of physicians (both Brazilian and foreign) from other fields, as well as with Brazilian nondoctors. The Brazilian Society of Neurosurgery death registry was used to obtain data that compared LEs from non-neurosurgeon physicians, as described in the national and international literature. BNLEs were also compared with the LEs of Brazilian citizens. Fifty-one neurosurgeons died between 2009 and 2016. All were males. The mean age at death was 68.31 ± 17.71 years. Among all-cause mortality, the breakdown was 20% cardiovascular diseases, 39% malignancies, 10% external factors, 6% gastrointestinal disorders, 12% neurologic illnesses, and 14% unknown causes. BNLE was shorter than LE of male Brazilian citizens. LE was similar among neurosurgeons and other doctors but shorter compared with Brazilian citizens. Further research is needed to provide data that can add to and confirm these results. Copyright © 2018 Elsevier Inc. All rights reserved.

Calvo-González, Elena

2014-01-01

In this article I examine how contemporary geneticists investigating the history and configuration of the Brazilian population engage with other academic disciplines. To do so I use as a case study some articles published by geneticists researching the presence of hemoglobin S variants in Brazil, in which there is a clear pretension to contribute to the analysis of issues such as slavery or Brazil's ethnic identity. By contrasting these studies with contemporary works from history and the social science, the explanatory centrality of "origin" in the genetic studies analyzed is problematized, as is the lack of interaction with the epistemological characteristics of other areas of knowledge.

Genetic diversity among brazilian isolates of beauveria bassiana: comparisons with non-brazilian isolates and other beauveria species

Aims: The genetic diversity of Beauveria bassiana was investigated by comparing isolates of this species to each other (49 from different geographical regions of Brazil and 4 from USA) and to other Beauveria spp. Methods and Results: The isolates were examined by multilocus enzyme electrophoresis (MLEE), amplified fragment length polymorphism (AFLP), and rDNA sequencing. MLEE and AFLP revealed considerable genetic variability among B. bassiana isolates. Several isolates from South and Southeast Brazil had high similarity coefficients, providing evidence of at least one population with clonal structure. There were clear genomic differences between most Brazilian and USA B. bassiana isolates. A Mantel test using data generated by AFLP provided evidence that greater geographical distances were associated with higher genetic distances. AFLP and rDNA sequencing demonstrated notable genotypic variation between B. bassiana and other Beauveria spp. Conclusion: Geographical distance between populations apparently is an important factor influencing genotypic variability among B. bassiana populations in Brazil. Significance and Impact of the Study: This study characterized many B. bassiana isolates. The results indicate that certain Brazilian isolates are considerably different from others and possibly should be regarded as separate species from B. bassiana sensu latu. The information on genetic variation among the Brazilian isolates, therefore, will be important to comprehending the population structure of B. bassiana in Brazil. ?? 2009 The Society for Applied Microbiology.

Juvenile nasopharyngeal angiofibroma (JNA) is a vascular tumor of the nasopharynx that accounts for 0.5% of all cancers of the head and neck. It primarily affects males aged 14-25 years. Of the many genes that mediate the development of JNA, GSTM1 has been most frequently associated with this vascular tumor. The loss of expression of GSTM1 (null genotype) is linked to the development of these tumors. The aim of this cross-sectional case study was to examine the prevalence of the GSTM1-null genotype in Brazilian patients with JNA. DNA was extracted from the leukocytes of blood samples from 10 patients. GSTM1 genotypes were analyzed using a PCR-based assay that was designed to identify the wild-type allele of GSTM1. All 10 patients (100%) were males, with a mean age of 17.8 years. The null genotype for GSTM1 was noted in 4 patients (40%)-1 (10%) at Fisch stage I, 1 (10%) at stage III, and 2 (20%) at stage II. No patient with this genotype had stage IV disease. There was no correlation between Fisch classification and GSTM1 genotype (P = .5695). The correlation between age at diagnosis and GSTM1 genotype was not significant (P = .728). The present findings indicate that there is evidence of an association between the GSTM1-null genotype and JNA in this studied Brazilian population.

The purpose of this study was to examine how key occupational therapy terminologies are used by Brazilian occupational therapists. A nominal group approach combined with a Delphi technique involving 31 Brazilian occupational therapists was applied. A sociolinguistic approach was adopted since it broadens our understanding of the social and cultural determinants of terminology consolidation. Brazilian occupational therapists were found to adopt the term activity more often than human action or doing. Even less often were praxis and occupation applied. No consensus was reached regarding which of the terms is most preferred. While Brazilian occupational therapists have been developing their profession from international standards, it is still embedded in local demands and policies. Additionally, the political context must be considered when building an international dialogue between members of a professional body. Such a dialogue could engage professionals from different countries in meaningful exchanges about their practices. These exchanges may lead to the development of solid professional communities that can contribute meaningfully to social change. Copyright 2010 John Wiley & Sons, Ltd.

Working with the Nobel Prize database, covering 1901-1966, the article examines the analytical potential of the participation of Brazilians both as nominees for the world's most prestigious award in science, the Nobel Prize, and also as invited nominators. Of the 18 Brazilians nominated for the Nobel, nine were in the category Peace, four in Literature, four in Physiology or Medicine, and one in Physics. The article comments on the nominations of Brazilian scientists in the categories of Physics and Physiology or Medicine, as well as on nominations by Brazilian nominators in these same two categories. It also discusses the process of science evaluation, based on the information attained through analysis of these data on the Nobel award.

Myelodysplastic syndromes (MDS) and juvenile myelomonocytic leukemia (JMML) are rare hematopoietic stem cell diseases affecting children. Cytogenetics plays an important role in the diagnosis of these diseases. We report here the experience of the Cytogenetic Subcommittee of the Brazilian Cooperative Group on Pediatric Myelodysplastic Syndromes (BCG-MDS-PED). We analyzed 168 cytogenetic studies performed in 23 different cytogenetic centers; 84 of these studies were performed in patients with confirmed MDS (primary MDS, secondary MDS, JMML, and acute myeloid leukemia/MDS+Down syndrome). Clonal abnormalities were found in 36.9% of the MDS cases and cytogenetic studies were important for the detection of constitutional diseases and for differential diagnosis with other myeloid neoplasms. These data show the importance of the Cooperative Group for continuing education in order to avoid a late or wrong diagnosis. PMID:23314345

Reimão, Sandra

Some documents produced by the government during the Brazilian military dictatorship have been made available for reference, including censors' reports on television and radio programs, plays, films, songs, advertisements and printed matter. Of the 500 or so reports on books, there is one that vetoes Programa de saúde: projetos e temas de higiene e saúde, an educational work that proposed actions to help students understand their sanitary conditions and acquire knowledge about health and health-promoting habits in this area. The argument for vetoing it was that the information could fall into the hands of poorly trained teachers, who could distort its content, causing serious damage to Brazilian youth. In this report we see evidence of the obscurantist, elitist posture adopted by the Department of Censorship of Public Entertainment, which aimed to restrict the circulation of information and curb debate.

Brazilian pharmaceutical diplomacy: social democratic principles versus soft power interests.

PubMed

Flynn, Matthew

2013-01-01

Current debates concerning the rise of health diplomacy are polarized between competing international relations theories of realism, based on power politics, and constructivist approaches, which emphasize the norms, values, and identities shaping foreign policies. A case study of Brazil's health diplomacy over the past 10 years, focusing on issues related to pharmaceuticals, seeks to provide data to assess these theories. The country's intellectual property disputes, multilateral lobbying efforts, and foreign assistance programs are contrasted with those of the United States, Mexico, and other countries. Instead of viewing Brazilian efforts as a form of soft power, the evidence suggests that the origins of Brazil's involvement and continued efforts in this arena stem more from values based on human rights and social democratic principles. A close examination of domestic political considerations leads to a more nuanced understanding of the drivers behind a country's health diplomacy.

This paper addresses the effects of the deregulation of the Brazilian air transportation industry in terms of the concentration of the market. We will show some metrics that are commonly used to study the concentration of the industry. This paper uses the Herfindhal- Hirschman Index. This index tends to zero in the competitive scenario, with a large number of small firms, and to one in case of a monopolistic scenario. The paper analyses the dynamics of the concentration of the Brazilian domestic air transportation market, in order to evaluate the effects of deregulation. We conclude that the Brazilian market presents oligopoly characteristics and aspects in its current structure that maintain the market concentrated in spite of the Deregulation measures adopted by the aeronautical authority. Keywords: Herfindhal-Hirschman Index, concentration, Deregulation

Balancing the subject composition of case and control groups to create homogenous ancestries between each group is essential for medical association studies. We explored the applicability of single-tube 34-plex ancestry informative markers (AIM) single nucleotide polymorphisms (SNPs) to estimate the African Component of Ancestry (ACA) to design a future case-control association study of a Brazilian urban sample. One hundred eighty individuals (107 case group; 73 control group) self-described as white, brown-intermediate or black were selected. The proportions of the relative contribution of a variable number of ancestral population components were similar between case and control groups. Moreover, the case and control groups demonstrated similar distributions for ACA <0.25 and >0.50 categories. Notably a high number of outlier values (23 samples) were observed among individuals with ACA <0.25. These individuals presented a high probability of Native American and East Asian ancestral components; however, no individuals originally giving these self-described ancestries were observed in this study. The strategy proposed for the assessment of ancestry and adjustment of case and control groups for an association study is an important step for the proper construction of the study, particularly when subjects are taken from a complex urban population. This can be achieved using a straight forward multiplexed AIM-SNPs assay of highly discriminatory ancestry markers.

This study investigated the association between resilience and posttraumatic stress disorder (PTSD) among Brazilian victims of urban violence. It also compared defense mechanisms, parental bonding, and childhood trauma between those who developed PTSD and those who did not. This cross-sectional case-control study included 66 adult subjects exposed to recent urban violence in southern Brazil - 33 with PTSD and 33 healthy controls matched by sex and age - who were administered the Resilience Scale, Defense Style Questionnaire, Parental Bonding Instrument, and Childhood Trauma Questionnaire. The statistical tests used were the McNemar test for categorical variables, the Wilcoxon signed-rank test for continuous asymmetric variables, and the paired Student t-test for continuous symmetric variables. The PTSD group showed lower total Resilience Scale scores compared with controls (128.4±20.7 vs. 145.8±13.1, respectively; p = 0.01), along with a lower ability to solve situations and lower personal values that give meaning to life (p = 0.019). They also had lower rates of mature defense mechanisms (p < 0.001) and higher rates of emotional (p = 0.001) and physical (p = 0.003) abuse during childhood. Lower levels of resilience, especially the ability to solve situations and having personal values that give meaning to life, immature defense mechanisms, and emotional and physical abuse in childhood are associated with PTSD in adult Brazilian victims of urban violence.

Information related to mastitis risk factors is useful for the design and implementation of clinical mastitis (CM) control programs. The first objective of our study was to model the risk of CM under Brazilian conditions, using cow-specific risk factors. Our second objective was to explore which risk factors were associated with the occurrence of the most common pathogens involved in Brazilian CM infections. The analyses were based on 65 months of data from 9,789 dairy cows and 12,464 CM cases. Cow-specific risk factors that could easily be measured in standard Brazilian dairy farms were used in the statistical analyses, which included logistic regression and multinomial logistic regression. The first month of lactation, high somatic cell count, rainy season and history of clinical mastitis cases were factors associated with CM for both primiparous and multiparous cows. In addition, parity and breed were also associated risk factors for multiparous cows. Of all CM cases, 54% showed positive bacteriological culturing results from which 57% were classified as environmental pathogens, with a large percentage of coliforms (35%). Coagulase-negative Staphylococcus (16%), Streptococcus uberis (9%), Streptococcus agalactiae (7%) and other Streptococci (9%) were also common pathogens. Among the pathogens analyzed, the association of cow-specific risk factors, such as Zebu breed (OR=5.84, 95%CI 3.77-10.77) and accumulated history of SCC (1.76, 95%CI 1.37-2.27), was different for CM caused by Coagulase-negative Staphylococcus and S. agalactiae in comparison to CM caused by coliforms. Our results suggest that CM control programs in Brazil should specially consider the recent history of clinical mastitis cases and the beginning of the lactations, mainly during the rainy season as important risk factor for mastitis.

The growing demand for qualified professionals is making software companies opt for distributed software development (DSD). At the project conception, communication and synchronization of information are critical factors for success. However problems such as time-zone difference between teams, culture, language and different development processes among sites could difficult the communication among teams. In this way, the main goal of this paper is to describe the solution adopted by a Brazilian team to improve communication in a multisite project environment. The purposed solution was based on the best practices described in the literature, and the communication plan was created based on the infrastructure needed by the project. The outcome of this work is to minimize the impact of communication issues in multisite projects, increasing productivity, good understanding and avoiding rework on code and document writing.

Pretests have been shown to contribute to improved performance on standardized tests by serving to facilitate development of individualized study plans. fmCASES is an existing validated examination used widely in family medicine clerkships throughout the country. Our study aimed to determine if implementation of the fmCASES National Examination as a pretest decreased overall failure rates on the end-of-clerkship National Board of Medical Examiners (NBME) subject examination, and to assess if fmCASES pretest scores correlate with student NBME scores. One hundred seventy-one and 160 clerkship medical students in different class years at a single institution served as the control and intervention groups, respectively. The intervention group took the fmCASES National Examination as a pretest at the beginning of the clerkship and received educational prescriptions based on the results. Chi-square analysis, Pearson correlation, and receiver operating curve analysis were used to evaluate the effectiveness and correlations for the intervention. Students completing an fmCASES National Examination as a pretest failed the end-of-clerkship NBME exam at significantly lower rates than those students not taking the pretest. The overall failure rate for the intervention group was 8.1% compared to 17.5% for the control group (P=0.01). Higher pretest scores correlated with higher NBME examination scores (r=0.55, P<0.001). fmCASES National Examination is helpful as a formative assessment tool for students beginning their family medicine clerkship. This tool introduces students to course learning objectives, assists them in identifying content areas most in need of study, and can be used to help students design individualized study plans.

Thermal Windows on Brazilian Free-tailed Bats Facilitate Thermoregulation during Prolonged Flight

The Brazilian free-tailed bat (Tadarida brasiliensis) experiences challenging thermal conditions while roosting in hot caves, flying during warm daylight conditions, and foraging at cool high altitudes. Using thermal infrared cameras, we identified hot spots along the flanks of free-ranging Brazilian free-tailed bats, ventral to the extended wings. These hot spots are absent in syntopic cave myotis (Myotis velifer), a species that forages over relatively short distances, and does not engage in long-distance migration. We hypothesized that the hot spots, or “radiators,” on Brazilian free-tailed bats may be adaptations for migration, particularly in this long-distance, high-flying species. We examined the vasculature of radiators on Brazilian free-tailed bats with transillumination to characterize the unique arrangements of arteries and veins that are positioned perpendicular to the body in the proximal region of the wing. We hypothesized that these radiators aid in maintaining heat balance by flushing the uninsulated thermal window with warm blood, thereby dissipating heat while bats are flying under warm conditions, but shunting blood away and conserving heat when they are flying in cooler air at high altitudes. We also examined fluid-preserved specimens representing 122 species from 15 of 18 chiropteran families and radiators appeared present only in species in the family Molossidae, including both sedentary and migratory species and subspecies. Thus, the radiator appears to be a unique trait that may facilitate energy balance and water balance during sustained dispersal, foraging, and long-distance migration. PMID:20811514

Abstract Congenital anomalies are already the second cause of infant mortality in Brazil, as in many other middle-income countries in Latin America. Birth defects are a result of both genetic and environmental factors, but a multifactorial etiology has been more frequently observed. Here, we address the environmental causes of birth defects – or teratogens – as a public health issue and present their mechanisms of action, categories and their respective maternal-fetal deleterious effects. We also present a survey from 2008 to 2013 of Brazilian cases involving congenital anomalies (annual average of 20,205), fetal deaths (annual average of 1,530), infant hospitalizations (annual average of 82,452), number of deaths of hospitalized infants (annual average of 2,175), and the average cost of hospitalizations (annual cost of $7,758). Moreover, we report on Brazilian cases of teratogenesis due to the recent Zika virus infection, and to the use of misoprostol, thalidomide, alcohol and illicit drugs. Special attention has been given to the Zika virus infection, now proven to be responsible for the microcephaly outbreak in Brazil, with 8,039 cases under investigation (from October 2015 to June 2016). From those cases, 1,616 were confirmed and 324 deaths occurred due to microcephaly complications or alterations on the central nervous system. Congenital anomalies impact life quality and raise costs in specialized care, justifying the classification of teratogens as a public health issue. PMID:28534929

Brazilian spotted fever is an acute febrile infectious disease caused by Rickettsia rickettsii, transmitted by tick bite. As this disease is rare and has high mortality rates in Brazil, the clinical aspects and epidemiological data may help the diagnosis. We report a case of Brazilian spotted fever in a 19-year-old patient who presented maculopapular exanthema in the palmar region and upper limbs, lymphadenopathy, fever, chills, headache, conjunctival hyperemia, nausea, vomiting, dyspnea, myalgia, developing neurological signs and abdominal pain. He was treated with doxycycline with clinical improvement. We emphasize the importance of the recognition of this disease by dermatologists as cutaneous manifestations are the key findings to establish early diagnosis and prevent complications.

Background While the research design of articles published in medical journals and in some physical therapy journals has already been evaluated, this has not been investigated in Brazilian physical therapy journals. Objective To describe the research design used in all articles published in Brazilian scientific journals that are freely available, have high Qualis rankings, and are relevant to physical therapy over a 7-year period. Method We extracted the bibliometric data, research design, research type (human or animal), and clinical area for all articles published. The articles were grouped into their level of evidence, and descriptive analyses were performed. We calculated the frequency, proportions of articles, and 95% confidence interval of these proportions with each research design in each journal. We cross-tabulated the clinical areas with research designs (expressed as number and percentages). Results A total of 1,458 articles from four Brazilian journals were found: Revista Brasileira de Fisioterapia, Revista Fisioterapia em Movimento, Revista Fisioterapia e Pesquisa, and Revista Acta Fisiátrica. The majority of articles were classified as level II of evidence (60%), followed by level III (29%) and level I (10%). The most prevalent research designs were cross-sectional studies (38%), single-case or case-series studies, and narrative reviews. Most articles reported human research and were in the musculoskeletal, neurologic, and cardiothoracic areas. Conclusions Most of the research published in Brazilian physical therapy journals used levels II and III of evidence. Increasing the publication rate of systematic reviews and randomized controlled trials would provide more high-quality evidence to guide evidence-based physical therapy practice. PMID:24675913

2017-09-01

This article analyzes data regarding cases of domestic violence treated by the emergency services through the following: the sociodemographic characteristics of the people who were treated; the events themselves; the evolution of care (from childhood to old age by gender); and the factors that differentiate cases of domestic violence compared to those committed by non-family members. Data from 24 Brazilian state capitals and the Federal District were analyzed, comprising 86 emergency services: a total of 4,893 individuals were surveyed. Of those people who were treated by emergency services, 26.6% suffered domestic violence: 40.0% were children/adolescents, 57.2% were adults and 2.8% were elderly. The adjusted model, which compared victims of violence committed by other family members with those who were not family members, showed that males were less likely to suffer from domestic violence; those that had fewer years of education were at increased risk; and that women were more likely to commit domestic violence compared to the category of "both genders". This study reinforces the fact that health sector professionals need to be able to deal with domestic violence by providing support, performing good practices, abiding by care protocols, taking care of injuries, and facilitating access to other services.

2011-01-01

The most used verbal fluency paradigms are semantic and letter fluency tasks. Studies suggest that these paradigms access semantic memory and executive function and are sensitive to frontal lobe disturbances. There are few studies in Brazilian samples on these paradigms. Objective The present study investigated performance, and the effects of age, on verbal fluency tasks in Brazilian children. The results were compared with those of other studies, and the consistency of the scoring criteria data is presented. Methods A sample of 119 children (7 to 10 years old) was submitted to the three phonemic fluency (F, A, M) tasks and three semantic fluency (animals, clothes, fruits) tasks. The results of thirty subjects were scored by two independent examiners. Results A significant positive correlation was found between the scores calculated by the two independent examiners. Significant positive correlations were found between performance on the semantic fluency task and the phonemic fluency task. The effect of age was significant for both tasks, and a significant difference was found between the 7- and 9-year-old subjects and between the 7- and 10-year-old subjects. The 8-year-old group did not differ to any of the other age groups. Conclusion The pattern of results was similar to that observed in previous Brazilian and international studies. PMID:29213727

Background The Liebowitz Social Anxiety Scale (LSAS) was the first evaluation instrument developed for screening for the signs and symptoms of Social Anxiety Disorder (SAD) and is currently still the most used worldwide. The aim of this study is to evaluate the ability of the LSAS - self-report version (LSAS-SR) to discriminate different Social Anxiety Disorder (SAD) clinical groups. Method The sample was composed of Brazilians university students, allocated into three different groups, i.e., cases (C=118), non-cases (NC=95) and subclinical cases (SC=39). To achieve the aim, calculations of the ROC Curve and ANOVA were performed. Results The results found were excellent regardless of the technique used, highlighting the discriminatory capacity of the LSAS-SR. The score equal to or greater than 32 is suggested as a cutoff score for the Brazilian population, since this presented balance between the standards evaluated and the ability to differentiate both clinical and subclinical SAD cases from non-cases. Conclusion Despite the specific sample used in this study being composed only of university students, the use of the LSAS-SR can be indicated, in the Brazilian setting, for SAD screening in both clinical and research contexts.

Serotonin (5-HT) regulates a variety of visceral and physiological functions, including sleep. Polymorphisms in the 5-HT2A receptor gene can alter its transcription, affecting the number of receptors in the serotoninergic system, contributing to obstructive sleep apnea syndrome (OSAS). The aim of this study was to determine the prevalence of the 102T-C and -1438G-A polymorphisms in the 5-HTR2A gene in Brazilian patients with and without OSAS. A cross-sectional study performed at the Otorhinolaryngology and Sleep Disorder Out Clinics, São José do Rio Preto Medical School, FAMERP. One hundred patients were examined as index cases and 100 persons as controls, of both genders to both groups. DNA was extracted from peripheral blood leukocytes, and the sites that encompassed both polymorphisms were amplified by PCR-RFLP. There was a significant prevalence of the male gender in index cases compared with the control group gender (p < 0.0001). There was no significant genotypic difference in the 102T-C polymorphism between the case and control groups (p = 1.000). The AA genotype of the -1438G-A polymorphism was more prevalent in the patients with OSAS compared with the controls (OR, 2.3; CI 95% 1.20-4.38; p = 0.01). There was no difference in the prevalence of the 102T-C polymorphism between patients with OSAS and the control group. Serotoninergic system dysfunction appeared to be related to OSAS. The -1438G-A polymorphism and OSAS are related in this studied Brazilian population.

ABSTRACT Metamemory measures provide subjective memory information and are relevant to investigate memory ability in aging. However, there is a lack of metamemory instruments available in Brazil. Objective: The aim of this study was to examine the psychometric properties of the Brazilian version of the Multifactorial Memory Questionnaire (MMQ), which evaluates different dimensions of subjective memory functioning, such as Feelings, Abilities and Strategies used in everyday life. Methods: The MMQ was translated into Portuguese and administered to 30 Brazilian elderly subjects. The participants underwent cognitive tests, mood scales and metamemory instruments. Results: Analyses revealed good internal consistency (Cronbach's a coefficient ranged from 0.75 to 0.89) and test-retest validity for each MMQ dimensions (positive correlations between two applications ranged from 0.75 to 0.8). Convergent validity evidence for the MMQ was confirmed by significant positive correlations (0.47 to 0.68) with dimensions of the Metamemory in Adulthood scale (MIA) (i.e., the Ability, Control, Self-efficacy and Strategy dimensions). Discriminant validity revealed no associations between the MMQ and cognitive performance, suggesting a weak metamemory-objective memory correspondence. Moreover, there was a negative correlation between MMQ-Ability subscale scores and mood symptoms (-0.63 for anxious symptoms, and -0.54 for depressive symptoms); and the Brazilian MMQ was comparable with MMQ translations to other languages. Conclusion: The Brazilian MMQ exhibits good psychometric properties and appears promising for clinical and research purposes. Additional studies are needed to further examine the psychometric properties of the Brazilian MMQ in a larger sample. PMID:29213442

Kinship and parentage analyses always involve one sample being compared to another sample or a few samples with a specific relationship question in mind. In most cases, the analysis of autosomal STR markers is sufficient to determine the genetic kinship. However, when genetic profiles are reconstructed from supposed relatives, for whom the family configuration available for analysis is deficient, the examination may be inconclusive. This study reports practical examples of actual cases analysing the efficiency of the chromosome X STR (STR-ChrX) markers. Three cases with different degrees of efficiency and impact were selected as follows: the identification of two charred bodies in a traffic accident, in which the family setting available was not complete, and one filiation analysis resulting from rape. This is the first paper reporting the use of the multiplex STR 12 ChrX in actual cases using the software Familias 1.8 and Brazilian regional frequency data. Our study clarifies the complex analysis using this powerful tool for professionals in the forensic science community, for both civil and criminal justice. We also discuss state-of-the-art ChrX STR markers and its implications and applications for legal procedures. The data presented here should be used in other studies of complex cases to improve the progress of the current justice system. Copyright © 2015 Forensic Science Society.

A researcher's review of adherence to forensic examination principles in homicide cases in Poland.

PubMed

Juszka, K; Juszka, K

The purpose of this paper is to verify adherence to forensic examination principles in homicide cases by analyzing the results of the author's own study of 90 court and prosecution cases from the period 2000-2010. The analyzed cases were sampled using the so-called multi-stage cluster sampling method, commonly used in social sciences in Poland. The cases were held in 17 organizational judiciary and prosecution units reporting to the Court of Appeal in Krakow and Appellate Prosecutor's Office in Krakow, respectively. The research tool was a questionnaire containing 40 relevant guidelines, covering both qualitative and quantitative features. In the 90 analyzed cases, a total of 251 forensic examination reports were prepared, including 110 site examination reports, 20 separate corpse examination reports, 29 personal examination reports and 92 object examination reports. The research aspects of forensic examinations will be analyzed from the perspective of adherence to the principles of conducting the same. As regards postulates de lege ferenda with respect to the implementation of forensic examination principles one should emphasize the need for using the appropriate form of description of corpse examination; the need for a more responsible attitude towards sealing off crime scenes and for recording information on sealing-off procedures in the examination report; the need for clear distinction of examination stages in drafting the examination report; the need for a detailed analysis of the examination carried out at its final stage at all times; the need for using professional vocabulary in all descriptions of examination activities in each case and the need for regular monitoring (by the person in charge of examination) also with regard to the tactical requirement to sign each sheet of the examination report. The tactical and procedural development of forensic examination principles, taking into account also the postulates de lege ferenda presented herein, will

Bioethics, biolaw, (bio)constitutional interpretation and biopatents under the light of Brazilian law.

Myszczuk, Ana Paula; de Meirelles, Jussara Maria Leal

The article briefly analyzes the concepts of the Bioethics, the Biolaw, the Bio-Constitution and the Biopatent. In order to do so, we will check some principles of the Bioethics, the newly added term the Biolaw, the concept of the Bio-Constitution or the Constitutional Biolaw, all used as means to solve conflicts of bio-juridical norms. Besides it formulates some questions about biopatents. It is here understood that the 1988 Brazilian Federal Constitution chose the human dignity principle as the core to be used in any Biomedicine related matter and this Law acts to bring some tools into a bio-constitutional interpretation. Among those tools are the fundamental rights and the protection of the environment. Some juridical limits to the private appropriation of the human genome, via patenting, are examined. The article considers the requirements imposed by the Law Act no 9279/96 (novelty, invention and industrial use), as well as some Brazilian constitutional dispositions concerning biopatents. In the conclusion, we argue that the Bioethics and the Biolaw principles are valuable instruments to support juridical decisions and to guide the establishment of possible limits on the use and/or development of the Biomedicine. Consequently when interpreting a concrete case, besides having a multidisciplinary analysis, we have refreshed classic juridical concepts. This is achieved by rethinking juridical fundamentals and opening up the space for the conceptualization of a Bio-Constitution interpretation.

Objective To evaluate whether there is any preference for citing journals from other countries to the detriment of Brazilian journals, in three Brazilian orthopedics journals. Methods All the references of articles published in 2011 by the journals Acta Ortopédica Brasileira, Coluna/Columna and Revista Brasileira de Ortopedia were evaluated to as certain how many of these came from Brazilian journals and how many from foreign journals. Results 3813 references distributed among 187 articles were analyzed. Out of this total, 306 (8.02%) were from Brazilian journals. There was no difference between the three journals analyzed. There were 76 articles (40.64%) without any citations of articles in Brazilian journals and only two articles (1%) cited more Brazilian articles than articles published elsewhere. Conclusion There is a need for Brazilian researchers to cite articles from Brazilian journals more often. PMID:26229879

Understanding the clinical spectrum of complicated Plasmodium vivax malaria: a systematic review on the contributions of the Brazilian literature

PubMed Central

2012-01-01

The resurgence of the malaria eradication agenda and the increasing number of severe manifestation reports has contributed to a renewed interested in the Plasmodium vivax infection. It is the most geographically widespread parasite causing human malaria, with around 2.85 billion people living under risk of infection. The Brazilian Amazon region reports more than 50% of the malaria cases in Latin America and since 1990 there is a marked predominance of this species, responsible for 85% of cases in 2009. However, only a few complicated cases of P. vivax have been reported from this region. A systematic review of the Brazilian indexed and non-indexed literature on complicated cases of vivax malaria was performed including published articles, masters' dissertations, doctoral theses and national congresses' abstracts. The following information was retrieved: patient characteristics (demographic, presence of co-morbidities and, whenever possible, associated genetic disorders); description of each major clinical manifestation. As a result, 27 articles, 28 abstracts from scientific events' annals and 13 theses/dissertations were found, only after 1987. Most of the reported information was described in small case series and case reports of patients from all the Amazonian states, and also in travellers from Brazilian non-endemic areas. The more relevant clinical complications were anaemia, thrombocytopaenia, jaundice and acute respiratory distress syndrome, present in all age groups, in addition to other more rare clinical pictures. Complications in pregnant women were also reported. Acute and chronic co-morbidities were frequent, however death was occasional. Clinical atypical cases of malaria are more frequent than published in the indexed literature, probably due to a publication bias. In the Brazilian Amazon (considered to be a low to moderate intensity area of transmission), clinical data are in accordance with the recent findings of severity described in diverse P

OBJECTIVES: To estimate the relative risk of death from work related injury in a steelworks, associated with exposure to various occupational hazards, sociodemographic factors, and medical history. MATERIAL AND METHODS: The study was a nested case-control design. It was based on a cohort of men employed in the steel plant of USIMINAS, Brazil between January 1977 and August 1990, who were followed up to November 1992. The cases were defined as all workers in the cohort who died from injury in the study period and whose death had been notified to the Brazilian Ministry of Labour as being related to work. Four controls per case, matched to cases on year of birth, were randomly selected from among workers employed in the plant at the time of death of the matching case. Data on potential risk factors for occupational injury were extracted from company records; for the controls these data were abstracted for the period preceding the death of the matching case. RESULTS: There were 37 deaths related to work injuries during the study period. Four surviving workers were selected as controls for each case, but for eight the personnel records were incomplete, leaving 140 controls in all. Significantly increased risk of fatal injury related to work was associated with exposure to noise, heat, dust and fumes, gases and vapours, rotating shift work, being a manual worker, and working in the steel mill, coke ovens, blast furnaces, and energy and water supply areas. Risk of fatal injury related to work increased with intensity of exposure to noise (P (trend) = 0.004) and heat (P < 0.001), and increased greatly with a hazard score that combined information on noise, heat, dust, and gas exposure (P < 0.001). Number of years of schooling (P = 0.03) and salary level (P = 0.03) were both negatively associated with risk. In a multivariate analysis including all these significant factors, only hazard score and area of work remained associated with death from injury related to work. The

The effects of sudden stratospheric warming (SSW) on ionosphere have been investigated by several scientists, using different observational techniques and model simulations. However, the minor SSW event during January 2012 is one of those that are less studied. Influences of several types of possible drivers—minor SSW event, changing solar flux, moderate geomagnetic storm on 22-25 January, and one of the largest solar proton events on 23-30 January—make it a challenging period to interpret. In the present study, the GPS-total electron content (TEC) measurements from a network of 72 receivers over the Brazilian region are considered. This network of 72 GPS-TEC locations lies between 5°N and 30°S (35°) latitudes and 35°W and 65°W (30°) longitudes. Further, two chains of GPS receivers are used to study the response of the equatorial ionization anomaly (EIA) in the Brazilian eastern and western sectors, as well as its day-to-day variability before and during the SSW-2012. It was noted that the TEC is depleted to the order of 30% all over the Brazilian region, from equator to beyond the EIA regions and from east to west sectors. It is also noticed that the EIA strengths at the east and west sectors were weakened during the SSW-2012. However, the Brazilian eastern sector was found to be more disturbed compared to the western sector during this SSW-2012 event.

To describe the prevalence of dental pain in Brazilian preschoolers, as well as its associated factors, considering a representative sample of that population group in Brazil. Cross-sectional study that used the analytical data of the national oral health survey (SB Brazil) carried out in 2010. A representative sample of Brazilian preschoolers aged 5 years was considered. Interviews were carried out (answered by parents/tutors), as well as clinical examinations in children. Descriptive, bivariate and multivariate analyzes were performed, described in odds ratios and 95% confidence interval (OR/95%CI). 7,280 preschoolers were included. Of these, 1520 (21.1%) had had dental pain in the last 6 months. The chance of the occurrence of dental pain was higher among those who used dental services (1.51 / 1.02 to 2.23), with tooth decay (3.08 / 2.08 to 4.56), that realized the need for dental treatment (3.96 / 2.48 to 6.34), whose parents reported dissatisfaction by children with their teeth and mouth (1.47 / 1.04 to 2.10) and those who reported impact of oral problems on quality of life (5.76 / 3.90 to 8.49). The prevalence of dental pain among Brazilian preschool children was relatively high, being associated with the use of dental services and the normative and subjective oral health status.

Haptoglobin gene subtypes in three Brazilian population groups of different ethnicities

PubMed Central

2009-01-01

Haptoglobin is a plasma hemoglobin-binding protein that limits iron loss during normal erythrocyte turnover and hemolysis, thereby preventing oxidative damage mediated by iron excess in the circulation. Haptoglobin polymorphism in humans, characterized by the Hp*1 and Hp *2 alleles, results in distinct phenotypes known as Hp1-1, Hp2-1 and Hp2-2, whose frequencies vary according to the ethnic origin of the population. The Hp*1 allele has two subtypes, Hp *1F and Hp *1S , that also vary in their frequencies among populations worldwide. In this work, we examined the distribution frequencies of haptoglobin subtypes in three Brazilian population groups of different ethnicities. The haptoglobin genotypes of Kayabi Amerindians (n = 56), Kalunga Afro-descendants (n = 70) and an urban population (n = 132) were determined by allele-specific PCR. The Hp*1F allele frequency was highest in Kalunga (29.3%) and lowest in Kayabi (2.6%). The Hp*1F/Hp*1S allele frequency ratios were 0.6, 1.0 and 0.26 for the Kayabi, Kalunga and urban populations, respectively. This variation was attributable largely to the Hp*1F allele. However, despite the large variation in Hp*1F frequencies, results of F ST (0.0291) indicated slight genetic differentiation among subpopulations of the general Brazilian population studied here. This is the first Brazilian report of variations in the Hp*1F and Hp*1S frequencies among non-Amerindian Brazilians. PMID:21637505

Purpose To describe a novel polymorphism in the γD-crystallin (CRYGD) gene in a Brazilian family with congenital cataract. Methods A Brazilian four-generation family was analyzed. The proband had bilateral lamellar cataract and the phenotypes were classified by slit lamp examination. Genomic DNA was extracted from peripheral blood and coding regions and intron/exon boundaries of the αA-crystallin (CRYAA), γC-crystallin (CRYGC), and CRYGD genes were amplified by polymerase chain reaction and directly sequenced. Results Sequencing of the coding regions of CRYGD showed the presence of a heterozygous A→G transversion at c.401 position, which results in the substitution of a tyrosine to a cysteine (Y134C). The polymorphism was identified in three individuals, two affected and one unaffected. Conclusions A novel rare variant in CRYGD (Y134C) was detected in a Brazilian family with congenital cataract. Because there is no segregation between the substitution and the phenotypes in this family, other genetic alterations are likely to be present. PMID:21866214

Moral sensitivity has been identified as a foundational component of ethical action. Diminished or absent moral sensitivity can result in deficient care. In this context, assessing moral sensitivity is imperative for designing interventions to facilitate ethical practice and ensure that nurses make appropriate decisions. The main purpose of this study was to validate a scale for examining the moral sensitivity of Brazilian nurses. A pre-existing scale, the Moral Sensitivity Questionnaire, which was developed by Lützén, was used after the deletion of three items. The reliability and validity of the scale were examined using Cronbach's alpha and factor analysis, respectively. Participants and research context: Overall, 316 nurses from Rio Grande do Sul, Brazil, participated in the study. Ethical considerations: This study was approved by the Ethics Committee of Research of the Nursing School of the University of São Paulo. The Moral Sensitivity Questionnaire contained 27 items that were distributed across four dimensions: interpersonal orientation, professional knowledge, moral conflict and moral meaning. The questionnaire accounted for 55.8% of the total variance, with Cronbach's alpha of 0.82. The mean score for moral sensitivity was 4.45 (out of 7). The results of this study were compared with studies from other countries to examine the structure and implications of the moral sensitivity of nurses in Brazil. The Moral Sensitivity Questionnaire is an appropriate tool for examining the moral sensitivity of Brazilian nurses.

Williams-Beuren Syndrome (WBS) is a multisystem disorder caused by the deletion of contiguous genes on chromosome 7q11.23. Ophthalmologic abnormalities and deficits in visual motor integration are important features of WBS. Here we describe our experience with Brazilian WBS patients and their ophthalmologic features. Sixteen patients with confirmed WBS went through thorough ophthalmologic examination. The most frequent ocular findings in our group of patients were stellate iris pattern (81.2%), hyperopic astigmatism (50%), hyperopia (37.5%), tortuosity of retinal vessel (37.5%) and strabismus (18.7%). This is the second report of ophthalmologic abnormalities in a group of Brazilian individuals with WBS. It is extremely valuable that specific populations are studied so that clinical diagnosis can be refined and management of patients can be driven to the most common presentations of the disease.

This article aims to review the studies that focused on smoking published between January 2010 and June 2012, in Arquivos Brasileiros de Cardiologia (Brazilian Archives of Cardiology), Brazilian Journal of Medical and Biological Research, Clinics (Sao Paulo), Jornal Brasileiro de Pneumologia (Brazilian Journal of Pulmonology), Revista da Associação Médica Brasileira (Journal of the Brazilian Medical Association) and Revista Brasileira de Cirurgia Cardiovascular (Brazilian Journal of Cardiovascular Surgery). During the aforementioned period 58 articles were published, 52 of which were original ones, addressing several aspects of smoking, such as effects on health, epidemiology, cessation and experimental studies.

Dysglycemias in pregnancy: from diagnosis to treatment. Brazilian consensus statement

PubMed Central

2010-01-01

There is an urgent need to find consensus on screening, diagnosing and treating all degrees of DYSGLYCEMIA that may occur during pregnancies in Brazil, considering that many cases of DYSGLYCEMIA in pregnant women are currently not diagnosed, leading to maternal and fetal complications. For this reason the Brazilian Diabetes Society (SBD) and the Brazilian Federation of Gynecology and Obstetrics Societies (FEBRASGO), got together to introduce this proposal. We present here a joint consensus regarding the standardization of clinical management for pregnant women with any degree of Dysglycemia, on the basis of current information, to improve medical assistance and to avoid related complications of Dysglycemia in pregnancy to the mother and the fetus. This consensus aims to standardize the diagnosis among general practitioners, endocrinologists and obstetricians allowing the dissemination of information in basic health units, public and private services, that are responsible for screening, diagnosing and treating disglycemic pregnant patients.

Diphyllobothriasis is an infection of the small intestine by the broad tapeworm Diphyllobothrium sp. The associated symptomatology is nonspecific, but megaloblastic anemia is a well-described complication. Although the infection is common in temperate regions, descriptions in South America have so far been limited to Chile, Peru, and a few cases in Argentina. This paper presents the first confirmed Brazilian case of diphyllobothriasis. A 29-years-old woman living in Salvador (state of Bahia) apparently acquired the infection from eating sushi. The diagnosis was based on fecal examination that revealed a large quantity of operculated eggs. A single dose of praziquantel (600 mg) was sufficient to cure the infection.

Configurations of power relations in the Brazilian emergency care system: analyzing a context of visible practices.

2013-09-01

In this paper, we make explicit the changing configurations of power relations that currently characterize the Brazilian Emergency Care System (SAMU) team in Belo Horizonte, Brazil. The SAMU is a recent innovation in Brazilian healthcare service delivery. A qualitative case study methodology was used to explore SAMU's current organizational arrangements, specifically the power relations that have developed and that demonstrate internal team struggles over space and defense of particular occupational interests. The argument advanced in this paper is that these professionals are developing their work in conditions of exposure, that is, they are always being observed by someone, and that such observational exposure provides the conditions whereby everyday emergency care practices are enacted such that practice is shaped by, as well as shapes, particular, yet recognizable power relationships. Data were collected through the observation of the SAMU's work processes and through semi-structured interviews. Research materials were analyzed using discourse analysis. In the emergency care process of work, visibility is actually embedded in the disciplinary context and can thus be analyzed as a technique applied to produce disciplined individuals through the simple mechanisms elaborated by Foucault such as hierarchical surveillance, normalizing judgment, and the examination. © 2012 John Wiley & Sons Ltd.

Physical and Physiological Profiles of Brazilian Jiu-Jitsu Athletes: a Systematic Review.

PubMed

Andreato, Leonardo Vidal; Lara, Francisco Javier Díaz; Andrade, Alexandro; Branco, Braulio Henrique Magnani

2017-12-01

Brazilian jiu-jitsu is a grappling combat sport that has intermittency as its core element; in other words, actions of high, moderate and low intensity are interspersed during matches, requiring a high level of conditioning to support optimal levels of performance for the total match time. The athletes perform from four to six matches during a day of competition, and this number may increase if the open-class competition, which is held parallel to the competition by weight class, is considered. This systematic review examined the physical and physiological profiles of Brazilian jiu-jitsu athletes. Only scientific researches dealing with the major fitness components of Brazilian jiu-jitsu athletes (i.e. body composition and somatotype, aerobic and anaerobic profiles, muscular strength and power) and using accepted methods that provided relevant practical applications for a Brazilian jiu-jitsu athlete's fitness training and/or performance were included in the current review. A computer literature search was carried out of the PubMed, ISI Web of Knowledge, SportDiscus and Scopus databases (up to January 2016). The database research generated 205 articles. After the application of inclusion and exclusion criteria, 58 studies were included for the present systematic review. A total of 1496 subjects were involved in all the selected investigations. Body fat is generally low for these athletes and the mesomorphic component is predominant. The different studies showed VO 2max values between 42 and 52 mL/kg/min, and it seems that aerobic fitness does not discriminate among Brazilian jiu-jitsu athletes of different competitive levels. There is a lack of scientific studies that have investigated anaerobic responses both in lower and upper limbs. Maximal dynamic, isometric and endurance strength can be associated with sporting success in Brazilian jiu-jitsu athletes. Although decisive actions during Brazilian jiu-jitsu matches are mainly dependent on muscular power, more

Brazilian women in politics.

Sanders, T G

1987-01-01

Women are gradually gaining influence in Brazilian politics, especially since recent advances in the women's movement, but they still play a limited role. There have been journals devoted to feminism and some notable feminists since 1850. In 1932 suffragettes in Brazil gained women the right to vote. Women's associations burgeoned in the 1940s and 1950s, culminating in a peak in number of women in national elected positions in 1965. A repressive military regime reversed the process, which resumed in 1975. 1975 was also significant for the Brazilian women's movement because of the U.N. Women's Year. Several large, influential feminist political action groups were formed, typically by upper class women with leftist views, although some church and union groups from lower classes also appeared. In 1979-1981, the coherence of these groups fell into schism and fragmentation, because of disagreements over the feminist political doctrines and roles, views on legality of abortion, and special interest groups such as lesbians. Another bitter dispute is opposition by leftist women to BEMFAM, the Brazilian Society of Family Welfare, which provides family planning for the poor: leftists oppose BEMFAM because it is supported by funds from "imperialist" countries such as the U.S. There are several types of feminists groups: those that emphasize health, sexuality and violence; those composed of lesbians; those originating from lower classes and unions; publicly instituted organizations. Brazilian law forbids discrimination against women holding public office, but in reality very few women actually do hold office, except for mayors of small towns and a few administrators of the Education and Social Security ministries. Political office in Brazil is gained by clientism, and since women rarely hold powerful positions in business, they are outsiders of the system. Brazilian women have achieved much, considering the low female literacy rate and traditional power system, but their

In Brazil most Construction and Demolition Waste (C&D waste) is not recycled. This situation is expected to change significantly, since new federal regulations oblige municipalities to create and implement sustainable C&D waste management plans which assign an important role to recycling activities. The recycling organizational network and its flows and components are fundamental to C&D waste recycling feasibility. Organizational networks, flows and components involve reverse logistics. The aim of this work is to introduce the concepts of reverse logistics and reverse distribution channel networks and to study the Brazilian C&D waste case.

This study aimed at describing the profiles of Brazilian and international studies published in orthodontic journals. The sample comprised 635 articles selected from two scientific journals, i.e., Dental Press Journal of Orthodontics and American Journal of Orthodontics and Dentofacial Orthopedics, which were analyzed at three different intervals over a 10-year period (1999 - 2004 - 2009). Articles were described in terms of knowledge domain, study design, and country of origin (or state of origin for Brazilian papers). The most frequent study designs adopted in international studies were cohort (23.9%) and cross-sectional (21.7%) designs. Among Brazilian papers, cross-sectional studies (28.9%) and literature reviews (24.6%) showed greater frequency. The topics most often investigated in international articles were dental materials (17%) and treatment devices (12.4%), with the latter topic being addressed by 16% of the Brazilian publications, followed by malocclusion, with 12.6%. In all cases, the most frequent countries of origin coincided with the countries of origin of each journal. The majority of the studies analyzed featured a low level of scientific evidence. Moreover, the findings showed that journals tend to publish studies produced in their own country of origin, and that there are marked discrepancies in the number of papers published by different Brazilian states.

The Amazon region reports the highest incidence of snakebite envenomings in Brazil. We aimed to describe the epidemiology of snakebites in the state of Amazonas and to investigate factors associated with disease severity and lethality. We used a nested case-control study, in order to identify factors associated with snakebite severity and mortality using official Brazilian reporting systems, from 2007 to 2012. Patients evolving to severity or death were considered cases and those with non-severe bites were included in the control group. During the study period, 9,191 snakebites were recorded, resulting in an incidence rate of 52.8 cases per 100,000 person/years. Snakebites mostly occurred in males (79.0%) and in rural areas (70.2%). The most affected age group was between 16 and 45 years old (54.6%). Fifty five percent of the snakebites were related to work activities. Age ≤15 years [OR=1.26 (95% CI=1.03-1.52); (p=0.018)], age ≥65 years [OR=1.53 (95% CI=1.09-2.13); (p=0.012)], work related bites [OR=1.39 (95% CI=1.17-1.63); (p<0.001)] and time to medical assistance >6 hours [OR=1.73 (95% CI=1.45-2.07); (p<0.001)] were independently associated with the risk of severity. Age ≥65 years [OR=3.19 (95% CI=1.40-7.25); (p=0.006)] and time to medical assistance >6 hours [OR=2.01 (95% CI=1.15-3.50); (p=0.013)] were independently associated with the risk of death. Snakebites represent an occupational health problem for rural populations in the Brazilian Amazon with a wide distribution. These results highlight the need for public health strategies aiming to reduce occupational injuries. Most cases of severe disease occurred in the extremes of age, in those with delays in medical attention and those caused by Micrurus bites. These features of victims of snakebite demand adequate management according to well-defined protocols, including prompt referral to tertiary centres when necessary, as well as an effective response from surveillance systems and policy makers for these

This paper presents the Ergonomic Work Analysis method in a Brazilian Dentist's office. Through the study, the constraints and the strategies in avoiding them were identified. It was found that dentists hardly use the position most indicated by the International Organization for Standardization (ISO) and the Federation Dentaire Internacionale (FDI) for both the patient and the dentist, which is respectively supine and 9 o'clock, due to the limited space and layout. Five types of treatments performed by the professional have been studied. The frequency and duration of actions in these treatments were accounted for and the standard positions adopted were identified. The AET was found to be a very suitable method to grasp the dentist's activity and build a point of view of the profession, which is characterized as: stressful, perfectionist and restrictive. Time management is presented as an important strategy to control the tension arising from performing the treatments.

The aging population calls for instruments to assess functional and cognitive impairment in the elderly, aiming to prevent conditions that affect functional abilities. Objective To verify the accuracy and reliability of the Pfeffer (FAQ) scale for the Brazilian elderly population and to evaluate the reliability and reproducibility of the translated version of the Pfeffer Questionnaire. Methods The Brazilian version of the FAQ was applied to 110 elderly divided into two groups. Both groups were assessed by two blinded investigators at baseline and again after 15 days. In order to verify the accuracy and reliability of the instrument, sensitivity and specificity measurements for the presence or absence of functional and cognitive decline were calculated for various cut-off points and the ROC curve. Intra and inter-examiner reliability were assessed using the Interclass Correlation Coefficient (ICC) and Bland-Altman plots. Results For the occurrence of cognitive decline, the ROC curve yielded an area under the curve of 0.909 (95%CI of 0.845 to 0.972), sensitivity of 75.68% (95%CI of 93.52% to 100%) and specificity of 97.26%. For the occurrence of functional decline, the ROC curve yielded an area under the curve of 0.851 (95%CI of 64.52% to 87.33%) and specificity of 80.36% (95%CI of 69.95% to 90.76%). The ICC was excellent, with all values exceeding 0.75. On the Bland-Altman plot, intra-examiner agreement was good, with p>0.05consistently close to 0. A systematic difference was found for inter-examiner agreement. Conclusion The Pfeffer Questionnaire is applicable in the Brazilian elderly population and showed reliability and reproducibility compared to the original test. PMID:29213959

All references in the articles published in Arquivos Brasileiros de Oftalmologia, Revista Brasileira de Cirurgia Cardiovascular, Revista da Associação Médica Brasileira, São Paulo Medical Journal, Arquivos Brasileiros de Endocrinologia e Metabologia, Clinics, Jornal Brasileiro de Pneumologia, Revista da Sociedade Brasileira de Medicina Tropical, Revista Brasileira de Psiquiatria e Acta Ortopédica Brasileira in the years 2011 and 2007 were analyzed, assessing the number of articles published in national and international journals. A total of 36,125 references from 1,462 articles published in the 10 aforementioned journals were analyzed. Of the total number, 4.242 (11.74%) were from Brazilian journals. There was no significant difference between the two analyzed periods. A total of 453 (30,98%) of the articles studied non-cited brazilian papers,and 81 (5.54%) articles had more Brazilian than international references. Of total references analyzed, 11.74% were related to articles published in Brazilian journals. This number, when compared to the percentage of Brazilian articles published in the medical area, demonstrates a good number of citations of national articles. Copyright © 2012 Elsevier Editora Ltda.

The authors examine land reform policies and their implications for violent conflict and resource use in the Brazilian Amazon. They identify the protagonists (land owners and squatters), derive their incentives to use violence, and show the role of legal inconsistencies as a basis for conflict. The authors describe the government agency involved in land reform, INCRA, and show that its intervention critically affects the actions of both squatters and land owners. Further, they point out the incentives for deforestation under land reform and associated insecure property rights to land. Forested lands are vulnerable to invasion by squatters and redistribution bymore » INCRA.

The maximum static respiratory pressures, namely the maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP), reflect the strength of the respiratory muscles. These measures are simple, non-invasive, and have established diagnostic and prognostic value. This study is the first to examine the maximum respiratory pressures within the Brazilian population according to the recommendations proposed by the American Thoracic Society and European Respiratory Society (ATS/ERS) and the Brazilian Thoracic Association (SBPT). To establish reference equations, mean values, and lower limits of normality for MIP and MEP for each age group and sex, as recommended by the ATS/ERS and SBPT. We recruited 134 Brazilians living in Belo Horizonte, MG, Brazil, aged 20-89 years, with a normal pulmonary function test and a body mass index within the normal range. We used a digital manometer that operationalized the variable maximum average pressure (MIP/MEP). At least five tests were performed for both MIP and MEP to take into account a possible learning effect. We evaluated 74 women and 60 men. The equations were as follows: MIP=63.27-0.55 (age)+17.96 (gender)+0.58 (weight), r(2) of 34% and MEP= - 61.41+2.29 (age) - 0.03(age(2))+33.72 (gender)+1.40 (waist), r(2) of 49%. In clinical practice, these equations could be used to calculate the predicted values of MIP and MEP for the Brazilian population.

Purpose  To translate into Portuguese, culturally adapt and validate the Uterine Fibroid Symptom - Quality of Life (UFS-QoL) questionnaire for Brazilian women with uterine leiomyoma. Methods  Initially, the UFS-QoL questionnaire was translated into Brazilian Portuguese in accordance with international standards, with subsequent cultural, structural, conceptual and semantic adaptations, so that patients were able to properly answer the questionnaire. Fifty patients with uterine leiomyoma and 19 patients without the disease, confirmed by abdominal pelvic examination and/or transvaginal ultrasound, were selected at the outpatient clinics of the Department of Gynecology of the Universidade Federal de São Paulo (Unifesp). The UFS-QoL questionnaire was administered to all women twice on the same day, with two different interviewers, with an interval of 15 minutes between interviews. After 15 days, the questionnaire was re-administered by the first interviewer. Reliability (internal consistency and test-retest), construct and discriminative validity were tested to ratify the questionnaire. Results  The reliability of the instrument was assessed by Cronbach's α coefficient with an overall result of 0.97, indicating high reliability. The survey results showed a high correlation ( p  = 0.94; p  ≤ 0.001). Conclusion  The UFS-QoL questionnaire was successfully adapted to the Brazilian Portuguese language and Brazilian culture, showing reliability and validity.

Twentieth-century astronomical heritage: the case of the Brazilian National Observatory

NASA Astrophysics Data System (ADS)

Barboza, Christina Helena

2015-08-01

The National Observatory of Brazil was created in 1827. It was initially focused on the practical teaching of Astronomy to the students of military and naval academies. Since the mid-nineteenth century to the early twentieth century it was installed over the ruins of a Jesuit church located in the center of Rio de Janeiro, capital of the Brazilian Empire.Due to the constant complaints of its successive directors, the search for a new site to house the Observatory began in 1911. The new headquarters of the institution were located on the hill of São Januário, a little further but still around the city center of Rio de Janeiro. Its inauguration took place in 1921.The main building of the new Observatory was based on one of the Brazilian pavilions of the Turin Exhibition of 1911, and its architecture can be characterized as eclectic. The pavilions intended to house the many telescopes were scattered in a large wooded area. Since 1985 all these facilities are protected by the Federal government, as a consequence of the same initiative that gave birth to the Museum of Astronomy and Related Sciences, which has the custody also of the Observatory’s former instruments, furniture, and documents.Although built in the early twentieth century the National Observatory new facilities reveal astronomical practices typical of the previous century. One of its most important activities was the determination of the legal time, a task that justifies its location in the urban environment. It was also responsible for the organization of expeditions destined to determine the geographical positions of railroads and the borders of Brazil. For this reason, the Museum of Astronomy has currently more than 3,000 portable instruments. Moreover, these instruments belong to the domain of Astronomy, but also to Geodesy, Meteorology, Electricity. Due to the creation of the Museum of Astronomy, this rich collection is now open to public visitation, and has become the object of scholarly

Brazilian Amazon Roads and Parks: Temporal & Spatial Deforestation Dynamics

Heterogeneous Forest Impacts of Transport Infrastructure: spatial frontier dynamics & impacts of Brazilian Amazon road changes Prior research on road impacts has almost completely ignored heterogeneity of impacts and as a result both empirically understated potential impact and missed policy potential. We note von Thunen's model suggests not only heterogeneity with distance from market but also specifically road impacts rising then falling with distance ('non-monoThunicity') Endogenous development and partial adjustment dynamics support this for the short run. Causal effects result from studying Brazilian Amazon deforestation (1976-87, 2000-04) using matching for short-run responses to lagged new roads changes (1968-75, 1985-00). We show the critical role of prior development, proxied by 1968 and 1985 road distances, for which exact matching addresses development trends and transforms impact estimates. Splitting the sample on this measure finds confirmation of the nonmonotonic predictions: new road impacts are relatively low if a prior road was close, such that prior transport access and endogenous development dynamics compete with the new road for influence, but also if a prior road was far, since first-decade adjustment in pristine areas is limited; yet in between these bounds, investments immediately raise deforestation significantly. This pattern helps to explain lower estimates within research on a single average impact. It suggests potential for REDD if a country chooses to shift its spatial transport networks. Protected Areas & Brazilian Amazon Deforestation: modeling and testing the impacts of varied PA strategies We model and then estimate the impacts of multiple types of protected areas upon 2000 - 2004 deforestation in the Brazilian Amazon. Our modeling starts with federal versus state objectives and predicts differences in both choice and implementation of each PA strategy that we examine. Our empirical examination brings not only breakdowns sufficient

Retrospective case report. A 35-year-old female presented with febrile illness and then decreased vision after repeat polymethyl methacrylate injections into her buttock muscles in Mexico. Examination was significant for retinal whitening, especially in the perifoveal areas, and intraretinal hemorrhages. Optical coherence tomography and fluorescein angiography imaging were consistent with small-vessel ischemic disease in the retina and choroid. Once systemic infection was ruled out, patient was treated with high-dose intravenous and then oral steroids. Vision recovery was good, with retinal atrophy on optical coherence tomography in the previous areas of retinal whitening. A Purtscher-like retinopathy with paracentral acute middle maculopathy and loss of vision may occur after filler injection below the neck, not just the face. This is the first report of vision loss caused by filler injected outside the face.

The introduction of strategic corporate sustainability policies is expected to result in the improvement of several issues in companies. One of these issues is work, which should involve greater well-being for workers. Within the context of production engineering, this research connects sustainability and work-related issues, the latter seen in light of the discipline of ergonomics. Based on case studies conducted at four companies considered sustainability benchmarks, we examined how the introduction of the theme of sustainability has influenced work-related issues. The elements analyzed here were the corporate sustainability strategy, organizational practices for deploying the strategy, and the work design phase. The last element is the moment in which work is prescribed in the organization. The results show that, despite the announcement of the inclusion of changes in work, there is not any explicit evidence confirming that such changes are considered as a requirement for corporate sustainability projects.

This paper presents an economic assessment of Brazilian agribusiness and its relationship with other economic sectors. It was found that, in 2011, agribusiness had a share of 18.45% (basic prices) and 19.77% (market prices) of Brazilian GDP. The tax burden of agribusiness (20.68%) was higher than that of other sectors (13.59%), despite agribusiness being a major contributor to the generation of foreign exchange, employment, and essential products, such as food. Brazilian agribusiness is a major employer, responsible for 29.39% of national employment. However, its average income is lower than in the other sectors of the Brazilian economy. Finally, agribusiness was found to be the biggest generator of foreign exchange, with a positive balance of trade. It was possible to conclude that agribusiness forms a strong link between agriculture and livestock, industry, and services in other economic sectors. For this reason, it can be said that the development of agribusiness is highly relevant to the process of Brazilian economic development and is therefore important to the progress of economic policies.

ABSTRACT Objective: To investigate whether Brazilian articles on cancer are published in journals with an impact factor and/or repercussion (measured by the number of citations) inferior to those that come from foreign organizations. Methods: A search was carried out in PubMed for the MeSH term “neoplasm” with the limits clinical trial, affiliation of the Brazilian author(s), and interval from July 1st, 2009 to June 30, 2010. Selected for matching were non-Brazilian related articles published from three months prior to three months after the date of publication of the Brazilian study. The numbers of citations were obtained from two databases, as well as the impact factor for the journals in which the articles were published. Results: Fortythree national and 876 related international articles were identified. The Brazilian publications had a mean impact factor of 3.000 versus 3.430 of the international ones (p=0.041). There was no statistically significant difference as to the number of citations between the two groups. The affiliation of the first author with a Brazilian or foreign organization did not significantly influence the number of citations or the impact factor. Conclusion: Brazilian articles are significantly less accepted in journals with higher impact factors, although it does not compromise its repercussion on the scientific community. PMID:23579739

We have attempted to determine the incidence, nature and clinical significance of TP53 mutation in a group of white (242 cases) and African-Brazilian (52 cases) patients with breast cancer. The interethnic admixture as estimated by STR markers showed that white subjects displayed 67.9+/-0.4%, 25.0+/-1.7% and 7.0%+/-1.6% and the black populations had 34.4+/-1.9%, 56.2+/-1.9 and 9.4+/-2.2% respectively of European, African and Amerindian genes. Clinical parameters such as age, lymph node status and steroid receptors were similar in both groups. African-Brazilian patients presented more advanced lesions. Mutation screening was performed using polymerase chain reaction-single strand conformation analysis followed by sequencing. Compared to whites (13.6%), a relatively high frequency of TP53 mutation was found in blacks (32.7%) (p=0.001). African-Brazilian women have a larger proportion of mutations in exons 5 and 7, whereas white women have more mutations in exon 8. Mutations within exon 4 were found only in tumors of white patients. The spectra of TP53 mutations show that A:T-->G:C nucleotide transversion and G:C-->C:G transition were more common in African-Brazilian women whereas G:C-->T:A transversion occurs very frequently in whites. A high prevalence of G:C-->A:T nucleotide transitions and deletions was detected in both groups. No association was found between p53 gene mutation and tumor or clinical parameters independently of the ethnic group. With a median follow-up of 35.6 months for whites and 43.4 months for the blacks, no differences in overall survival were found. If white patients were stratified according to the type and location of TP53 mutations, patients with mutations affecting amino acids directly involved in DNA or Zn binding displayed a poor prognosis. The pattern of mutations found in our population seems to reflect a base line pattern observed in populations with similar ethnic profile with some modifications, which might be derived from specific

Low back pain (LBP) is little explored in the aging population especially when considering age-relevant and culturally dependent outcomes. We aimed to describe socio-demographic and clinical characteristics of Brazilian older people with a new episode of LBP presenting to primary care. We sourced baseline information on socio-demographic, pain-related and clinical characteristics from 602 older adults from the Brazilian Back Complaints in the Elders (Brazilian BACE) study. We analyzed differences in pain, disability, functional capacity and psychosocial factors between sub-groups based on age (i.e. participants aged 55-74 or ≥75 years), education (i.e. those with four years or less of schooling or those with more than four years of schooling) and income (i.e. participants who reported earning two or less minimal wages or three and more). Participants presented severe LBP (7.18/10, SD: 2.59). Younger participants were slightly more disabled (mean difference 1.29 points, 95% confidence interval [CI]: 0.03/5.56), reporting poorer physical health, and less fall-related self-efficacy (mean difference of 2.41, 95% CI 0.35/4.46). Those less educated, and those with income equal or less than two minimum wages had more disability, pain catastrophizing and worse functional capacity. This was the first study showing that Brazilian older adults with LBP present high levels of functional disability and psychological distress, especially those with low socioeconomic status.

There is no systematic assessment of the quality of scientific production in the specialty of hand surgery in our setting. This study aimed to systematically assess the status of evidence generation relating to hand surgery and to evaluate the reproducibility of the classification method based on an evidence pyramid. Secondary study conducted at Universidade Federal de São Paulo (Unifesp) and Faculdade Estadual de Medicina de Marília (Famema). Two researchers independently conducted an electronic database search for hand surgery studies published between 2000 and 2009 in the two main Brazilian orthopedic journals (Acta Ortopédica Brasileira and Revista Brasileira de Ortopedia). The studies identified were subsequently classified according to methodological design (systematic review of the literature, randomized clinical trial, cohort study, case-control study, case series and other studies) and evidence level (I to V). A total of 1,150 articles were evaluated, and 83 (7.2%) were included in the final analysis. Studies with evidence level IV (case series) accounted for 41 (49%) of the published papers. Studies with evidence level V (other studies) accounted for 12 (14.5%) of the papers. Only two studies (2.4%) were ranked as level I or II. The inter-rater reproducibility was excellent (k = 0.94). Hand surgery articles corresponded to less than one tenth of Brazilian orthopedic production. Studies with evidence level IV were the commonest type. The reproducibility of the classification stratified by evidence level was almost perfect.

Necessity to review the Brazilian regulation about fluoride toothpastes

Cury, Jaime Aparecido; Caldarelli, Pablo Guilherme; Tenuta, Livia Maria Andaló

2015-01-01

The aim of this study was to evaluate the adequacy of the Brazilian legislation about fluoride toothpaste. A search was conducted in LILACS, Medline and SciELO databases about the fluoride concentration found in Brazilians toothpastes, using descriptors on health. Publications since 1981 have shown that some Brazilian toothpastes are not able to maintain, during their expiration time, a minimum of 1,000 ppm F of soluble fluoride in the formulation. However, the Brazilian regulation (ANVISA, Resolution 79, August 28, 2000) only sets the maximum total fluoride (0.15%; 1,500 ppm F) that a toothpaste may contain but not the minimum concentration of soluble fluoride that it should contain to have anticaries potential, which according to systematic reviews should be 1,000 ppm F. Therefore, the Brazilian regulation on fluoride toothpastes needs to be revised to assure the efficacy of those products for caries control. PMID:26487295

Brazilian LTER: ecosystem and biodiversity information in support of decision-making.

Brazil officially joined the International Long Term Ecological Research (ILTER) network in January 2000, when nine research sites were created and funded by the Brazilian Council for Science and Technology (CNPq). Two-years later some positive signs already emerge of the scientific, social and political achievements of the Brazilian LTER program. We discuss examples of how ecosystem and biodiversity information gathered within a long-term research approach are currently subsidizing decision-making as regards biodiversity conservation and watershed management at local and regional scales. Success in this respect has often been related to satisfactory communication between scientists, private companies, government and local citizens. Environmental education programs in the LTER sites are playing an important role in social and political integration. Most examples of integration of ecological research to decision-making in Brazil derive from case studies at local or regional scale. Despite the predominance of a bottom-up integrative pathway (from case studies to models; from local to national scale), some top-down initiatives are also in order, such as the construction of a model to estimate the inpact of different macroeconomic policies and growth trajectories on land use. We believe science and society in Brazil will benefit of the coexistence of bottom-up and top-down integrative approaches.

This paper analyzes the medical care given at Brazilian urgent and emergency healthcare services to people injured by firearms in 2014. A cross-sectional study was carried out on care given to patients with firearms injuries in 24 capital cities of Brazilian states and in the Brazilian Federal District, included in the VIVA Survey. Simple and relative frequencies of the variables related to the patients and to the event were calculated, and a logistic model for complex samples was applied adopting care for firearms injuries patients as outcome. The results show the following percentages of care events as caused by firearms: 0.7% for the category 'other accidents (other than transport-related accidents)', 1.5% for self-inflicted injuries, 15.9% for injuries due to assault, and 65.1% of cases arising from legal intervention. The care given was predominantly to young male adults (age 20-39), of mixed race and with a low level of schooling. The most common injuries were: to arms and legs; and to multiple organs. The paper concludes by discussing the efforts to control firearms held by the public in Brazil, and how they can lead to severe and lethal outcomes in quarrels and interpersonal disputes.

Abstract Objective: To obtain an overview of available information on the anthropometric assessment of Brazilian children attending daycare centers. Data source: A literature search was carried out in the PubMed, LILACS and SciELO databases of studies published from 1990 to 2013 in Portuguese and English languages. The following search strategy was used: (nutritional status OR anthropometrics OR malnutrition OR overweight) AND daycare centers, as well as the equivalent terms in Portuguese. In the case of MEDLINE search, the descriptor Brazil was also used. Data synthesis: It was verified that the 33 studies included in the review were comparable from a methodological point of view. The studies, in general, were characterized by their restrictive nature, geographical concentration and dispersion of results in relation to time. Considering the studies published from 2010 onwards, low prevalence of acute malnutrition and significant rates of stunting and overweight were observed. Conclusions: Despite the limitations, considering the most recent studies that used the WHO growth curves (2006), it is suggested that the anthropometric profile of Brazilian children attending daycare centers is characterized by a nutritional transition process, with significant prevalence of overweight and short stature. We emphasize the need to develop a multicenter survey that will more accurately define the current anthropometric nutritional status of Brazilian children attending daycare centers. PMID:26553574

Peters, A; Raidal, S R; Blake, A H; Atkinson, M M; Atkinson, P R; Eggins, G P

2012-01-01

A 23-year-old Brazilian, or lowland, tapir with a 6-month history of loss of body condition developed clinical signs and laboratory findings consistent with liver failure. The animal was euthanased and a diagnosis of hepatic haemochromatosis was made based on histopathology. Two other healthy tapirs in the same collection had chronically elevated serum and tissue iron concentrations. The excessive accumulation of iron in tissues with resultant tissue damage (i.e. haemochromatosis) has been reported in a range of captive species. This and other reported cases of haemochromatosis in the Brazilian tapir would suggest that this condition is an important consideration in the management of this species in zoos. Further research into the endogenous regulation of iron metabolism, especially the role of hepcidin, in tapirs and other species at risk of iron storage disorders may be helpful in the prevention of this condition. © 2012 The Authors.

2012-01-01

The Brazilian Health System has two different forms of access, public and private. The purpose of the public health system is to provide universal, complete access, free of charge, for the entire population. The private sector is composed by people who have private insurance. Nowadays, about 43 million Brazilians, or 26.3% of the population, have private health insurance. The main motivations of the physicians for the strike were the low payment for medical services and the constant interference of the private health insurance companies in medical autonomy. For this reason, Brazilian physicians held a 24-hour strike against the Medical Insurance Companies that did not accept to negotiate new fees in almost all Brazilian states. At least 120,000 physicians from all specialties stopped elective activities during that day, only providing urgent or emergency care. It is estimated that the strike affected 25 to 35 million Brazilians, about 76% of the total number of medical insurance users. Copyright © 2012 Elsevier Inc. All rights reserved.

The prevalence of obesity, pre-diabetes, and type 2 diabetes (T2D) is increasing worldwide, especially in the developing nations of South America. Brazil has experienced an exponential increase in the prevalence of these chronic non-communicable diseases. The rising prevalence is probably due to changing eating patterns, sedentary living, and a progressive aging of the population. These trends and their underlying causes carry untoward consequences for all Brazilians and the future of Brazilian public health and the healthcare system. Lifestyle changes that include healthy eating (nutrition therapy) and regular physical activity (structured exercise) represent efficient inexpensive measures to prevent and/or treat the aforementioned disorders and are recommended for all afflicted patients. Regrettably, the implementation of lifestyle changes is fraught with clinical and personal challenges in real life. The transcultural Diabetes Nutrition Algorithm (tDNA) is a therapeutic tool intended to foster implementation of lifestyle recommendations and to improve disease-related outcomes in common clinical settings. It is evidence-based and amenable to cultural adaptation. The Brazilian Diabetes Association, Society of Cardiology and Ministry of Health guidelines for nutrition therapy and physical exercise were considered for the Brazilian adaptation. The resultant tDNA-Brazil and its underlying recommendations are presented and explained.

Anthropometric data are essential for the design of military equipment including sizing of aircraft cockpits and personal gear. Currently, there are no anthropometric databases specific to Brazilian military personnel. The aim of this study was to create a Brazilian anthropometric database of Air Force pilots. The methods, protocols, descriptions, definitions, landmarks, tools and measurements procedures followed the instructions outlined in Measurer's Handbook: US Army and Marine Corps Anthropometric Surveys, 2010-2011 - NATICK/TR-11/017. The participants were measured countrywide, in all five Brazilian Geographical Regions. Thirty-nine anthropometric measurements related to cockpit design were selected. The results of 2133 males and 206 females aged 16-52 years constitute a set of basic data for cockpit design, space arrangement issues and adjustments, protective gear and equipment design, as well as for digital human modelling. Another important implication is that this study can be considered a starting point for reducing gender bias in women's career as pilots. Practitioner Summary: This paper describes the first large-scale anthropometric survey of the Brazilian Air Force pilots and the development of the related database. This study provides critical data for improving aircraft cockpit design for ergonomics and comprehensive pilot accommodation, protective gear and uniform design, as well as digital human modelling.

Chagas disease is an emergent tropical disease in the Brazilian Amazon Region, with an increasing number of cases in recent decades. In this region, the sylvatic cycle of Trypanosoma cruzi transmission, which constitutes a reservoir of parasites that might be associated with specific molecular, epidemiological and clinical traits, has been little explored. The objective of this work is to genetically characterize stocks of T. cruzi from human cases, triatomines and reservoir mammals in the State of Amazonas, in the Western Brazilian Amazon. We analyzed 96 T. cruzi samples from four municipalities in distant locations of the State of Amazonas. Molecular characterization of isolated parasites from cultures in LIT medium or directly from vectors or whole human blood was performed by PCR of the non-transcribed spacer of the mini-exon and of the 24 S alfa ribosomal RNA gene, RFLP and sequencing of the mitochondrial cytochrome c oxidase subunit II (COII) gene, and by sequencing of the glucose-phosphate isomerase gene. The T. cruzi parasites from two outbreaks of acute disease were all typed as TcIV. One of the outbreaks was triggered by several haplotypes of the same DTU. TcIV also occurred in isolated cases and in Rhodnius robustus. Incongruence between mitochondrial and nuclear phylogenies is likely to be indicative of historical genetic exchange events resulting in mitochondrial introgression between TcIII and TcIV DTUs from Western Brazilian Amazon. TcI predominated among triatomines and was the unique DTU infecting marsupials. DTU TcIV, rarely associated with human Chagas disease in other areas of the Amazon basin, is the major strain responsible for the human infections in the Western Brazilian Amazon, occurring in outbreaks as single or mixed infections by different haplotypes.

This study aims to present the percentages of the Brazilian population holding health insurance plans, itemized by social-demographic characteristics, based on the data of the National Health Survey carried out in 2013, and to compare this information with the administrative data of the National Supplementary Health Agency for the same year. Data from the National Health Survey, and from the Beneficiaries Information System of the National Health Agency for the year 2013, were used. The percentage of people having a health plan was described according to stratification for: all of Brazil, urban/rural, Brazilian official Regions, Brazilian States and state capitals, gender, age group, level of schooling, position in the workforce, ethnic classification, and self-assessed state of health. Results include the following: The percentage of people saying they had some health plan in Brazil was 27.9% (CI 95%: 27.1-28.8). A significant difference was found relating to level of schooling - the percentage being highest for those who stated they had complete secondary education (68.8% CI 95%: 67.2-70.4) and for those who said they were currently in work (32.5% CI 95%: 31.5-33.5). The increase in health plan coverage in the Brazilian population reflects the improvement of the suply of employment and the growth in the country's economy.

2014-01-01

This article aims to reconstruct the history of the term "racial democracy" in Brazilian sociological literature. This term, usually associated with the idea of "myth", is used in many studies of race relations without little definition or clarity. This article retraces its origins, in particular by showing that the concept is not the invention of Gilberto Freyre. It then examines the evolution of its use with particular emphasis on Unesco's research in the 1950s and the texts of Florestan Fernandes in the 1960s.

From a scenario of political and technological changes in work and health education, the purpose of this study was to understand the ethics discourse in nurses' education process in Brazilian nursing schools. A research was performed with a qualitative approach, characterized as a case study, involving six schools of a region in the south of Brazil. The data were collected by focal groups involving 50 teachers. The results were organized in three categories: (1) experience and motivation to teach ethics and bioethics, (2) indicators of change identified in global and local contexts and (3) challenges in the education of ethics, values and related themes. The teachers have highlighted complex elements related to scientific, educational and professional contexts, and pointed out the need for a critical perspective on the professional scenario and on their own situations as nurses and educators. The analyzed discourse brings to light the topic of ethics, seen as peculiar to the present day and in intimate connection with the daily routine of clinical, pedagogical and political professional practices. The findings suggest that the reflections on nurses' ethics education should not be limited to discussing content and pedagogical strategies but should be extended to include a commitment to the adoption of values in professional practice and to the process of the construction of a professional identity.

2014-02-01

This study examines the acculturation effects on metabolic syndrome (MetS), and its related factors, among immigrant Japanese-Brazilian men in Japan. Quantitative and qualitative approaches were utilized. In the quantitative study (n = 149), multiple logistic regression analyses estimated the impact of length of residence and arrival age on MetS. For the qualitative study, five focus group discussions were conducted with participants (n = 26) from the quantitative study sample. The oldest arrival age group was more likely to have MetS (OR, 95% CI 4.41, 1.09-17.78) after adjusting for covariates; whereas, length of residence had no association with MetS. The oldest arrival age group, with shorter residence period, was also associated with increased MetS prevalence. Qualitative results identified participants' Brazilian dietary habits as being potential risk factors for MetS. Japanese-Brazilian immigrant men with older arrival age in Japan were more likely to suffer from MetS, especially shortly after arrival.

Study of immigrant populations may contribute to a better understanding of the epidemiology of diseases associated with the aging process. We examined the prevalence of cardiovascular risk factors, including apolipoprotein E (ApoE) polymorphism, in elderly subjects who were born in Japan, migrated to South Brazil and have lived in that region for over 40 years, versus a group of elderly, locally born Brazilians living in the same region. These Japanese subjects came to Brazil after World War II (1950-1960) from several Japanese cities, mainly Nagasaki, Kumamoto and Hokkaido. Among 1007 subjects genotyped for ApoE polymorphism, we selected 540 elderly subjects (>60 years old), consisting of 270 Japanese-Brazilians and 270 Brazilians of European ancestry from Rio Grande do Sul State (Gaucha population). The Japanese-Brazilian group had significantly lower prevalences of obesity, type 2 diabetes mellitus, dyslipidemia, and metabolic syndrome than did the Gaucho population group. ApoE polymorphism frequencies were similar in the two groups. The differences in cardiovascular risk factors observed in the two populations cannot be explained by ApoE polymorphism; they could be related to conservation of Japanese lifestyle habits, such as diet.

The Brazilian pharmaceutical industry is heavily dependent on external sources of inputs, capital, and technology. However, the emergence of technological opportunities and the development of biotechnology and the decline of the patent boom and resulting advances by generic drugs have opened windows of opportunities for the local industry. The article examines the Brazilian industry's innovative behavior vis-à-vis these opportunities, showing that although the industry as a whole invests little in innovation, a few large Brazilian companies have expanded their market share and stepped up their investments in research and development, supported by public policies for innovation. Resumo: A indústria farmacêutica brasileira caracteriza-se pela grande dependência de fontes externas de insumos, capital e tecnologia. O surgimento de oportunidades tecnológicas, associadas ao desenvolvimento da biotecnologia e ao fim do boom das patentes com o consequente avanço dos medicamentos genéricos, entretanto, vem abrindo janelas de oportunidades para a indústria local. Este artigo examina o comportamento inovador da indústria brasileira à luz dessas oportunidades, revelando que, embora o conjunto da indústria mantenha baixos níveis de investimentos em inovação, um pequeno grupo de grandes empresas nacionais vem ampliando sua participação no mercado e intensificando seus investimentos em pesquisa e desenvolvimento, apoiados por políticas públicas de inovação.

This study evaluated the indoor air quality in Brazilian universities by comparing thirty air-conditioned (AC) (n = 15) and naturally ventilated (NV) (n = 15) classrooms. The parameters of interest were indoor carbon dioxide (CO2), temperature, relative humidity (RH), wind speed, viable mold, and airborne dust levels. The NV rooms had larger concentration of mold than the AC rooms (1001.30 ± 125.16 and 367.00 ± 88.13 cfu/m3, respectively). The average indoor airborne dust concentration exceeded the Brazilian standards (<80 µg/m3) in both NV and AC classrooms. The levels of CO2 in the AC rooms were significantly different from the NV rooms (1433.62 ± 252.80 and 520.12 ± 37.25 ppm, respectively). The indoor air quality in Brazilian university classrooms affects the health of students. Therefore, indoor air pollution needs to be considered as an important public health problem.

A survey was designed to examine the use of dietary supplements by Brazilian physical education professionals. The study included 131 Brazilian physical education professionals (83 men and 48 women). A descriptive statistical analysis was performed (mean, standard deviation, and absolute and relative frequencies). A chi-square test was applied to evaluate differences in use of dietary supplements according to particular variables of interest (p < .05). Forty-nine percent of respondents used dietary supplements. Approximately 59% of dietary supplement users took two or more kinds of supplements. Among users of supplements, men professionals (73%) consumed more dietary supplements than women (27%). The most-consumed dietary supplement was whey protein (80%). The results showed a higher use of dietary supplements by men. The most-consumed supplements were rich in protein. The consumption of dietary supplements by almost half of the participants in this study suggests that participants did not consider their dietary needs to be met by normal diet alone.

The air transportation network in a country has a great impact on the local, national and global economy. In this paper, we analyze the air transportation network in Brazil with complex network features to better understand its characteristics. In our analysis, we built networks composed either by national or by international flights. We also consider the network when both types of flights are put together. Interesting conclusions emerge from our analysis. For instance, Viracopos Airport (Campinas City) is the most central and connected airport on the national flights network. Any operational problem in this airport separates the Brazilian national network into six distinct subnetworks. Moreover, the Brazilian air transportation network exhibits small world characteristics and national connections network follows a power law distribution. Therefore, our analysis sheds light on the current Brazilian air transportation infrastructure, bringing a novel understanding that may help face the recent fast growth in the usage of the Brazilian transport network.

To compare clinical trials published in Brazilian journals of ophthalmology and in foreign journals of ophthalmology with respect to the number of citations and the quality of reporting [by applying the Consolidated Standards for Reporting Trials (CONSORT) statement writing standards]. The sample of this systematic review comprised the two Brazilian journals of ophthalmology indexed at Science Citation Index Expanded and six of the foreign journals of ophthalmology with highest Impact Factor® according ISI. All clinical trials (CTs) published from January 2009 to December 2010 at the Brazilians journals and a 1:1 randomized sample of the foreign journals were included. The primary outcome was the number of citations through the end of 2011. Subgroup analysis included language. The secondary outcome included likelihood of citation (cited at least once versus no citation), and presence or absence of CONSORT statement indicators. The citation counts were statistically significantly higher (P<0.001) in the Foreign Group (10.50) compared with the Brazilian Group (0.45). The likelihood citation was statistically significantly higher (P<0.001) in the Foreign Group (20/20 - 100%) compared with the Brazilian Group (8/20 - 40%). The subgroup analysis of the language influence in Brazilian articles showed that the citation counts were statistically significantly higher in the papers published in English (P<0.04). Of 37 possible CONSORT items, the mean for the Foreign Group was 20.55 and for the Brazilian Group was 13.65 (P<0.003). The number of citations and the quality of reporting of clinical trials in Brazilian journals of ophthalmology still are low when compared with the foreign journals of ophthalmology with highest Impact Factor®.

This is a cross-sectional study examining the association between child psychiatric disorders and potential early vulnerabilities (disability, low intellectual quotient, and negative dimensions of the temperament trait self-directedness (low resourcefulness, low purposefulness, low enlightened second nature), controlling for the potential confounders: familial and community adversities. Four probabilistic samples of second-to-sixth grade students from public schools in four towns from different Brazilian regions (N = 1620). The following instruments were applied: the K-SADS-PL (to assess child/adolescent psychiatric disorders); the Ten-Question Screen (to measure child disability); three structured questions used as proxy of self-directedness; and the reduced version of the WISC-III to measure IQ. To evaluate familial/community adversities: Self-Report Questionnaire-SRQ-20 (to assess maternal/primary caretaker anxiety/depression); questions derived from structured questionnaires (to measure child abuse, marital physical violence, neighborhood violence); Brazilian Association of Research Companies questionnaire (to evaluate poverty/socioeconomic status). Trained psychologists interviewed mothers/primary caretakers and evaluated children/adolescents individually. A final logistic regression model showed that children/adolescents with low resourcefulness, low purposefulness, low enlightened second nature, lower IQ and disability were more likely to present any child psychiatric disorders. Early vulnerabilities such as low IQ, presence of disability, and dimensions of temperament were associated with psychiatric disorders among Brazilian elementary school children, after controlling for familial and ecological confounders. These early vulnerabilities should be considered in mental

Setting Treatment default is a serious problem in tuberculosis control because it implies persistence of infection source, increased mortality, increased relapse rates and facilitates the development of resistant strains. Objective This study analyzed tuberculosis treatment default determinants in the Amazonas State to contribute in planning appropriate control interventions. Design Observational study with a retrospective cohort using Brazilian Disease Notification System data from 2005 to 2010. A nested case control study design was used. Patients defaulting from treatment were considered as ‘cases’ and those completing treatment as ‘controls’. In the analysis, 11,312 tuberculosis patients were included, 1,584 cases and 9,728 controls. Results Treatment default was observed to be associated to previous default (aOR 3.20; p<0.001), HIV positivity (aOR 1.62; p<0.001), alcoholism (aOR 1.51; p<0.001), low education level (aOR 1.35; p<0.001) and other co-morbidities (aOR 1.31; p = 0.05). Older patients (aOR 0.98; p = 0.001) and DOT (aOR 0,72; p<0.01) were considered as protective factor for default. Conclusions Associated factors should be considered in addressing care and policy actions to tuberculosis control. Information on disease and treatment should be intensified and appropriate to the level of education of the population, in order to promote adherence to treatment and counter the spread of multidrug resistance to anti-TB drugs.

The Brazilian Twin Registry (BTR) was established in 2013 and has impelled twin research in South America. The main aim of the initiative was to create a resource that would be accessible to the Brazilian scientific community as well as international researchers interested in the investigation of the contribution of genetic and environmental factors in the development of common diseases, phenotypes, and human behavior traits. The BTR is a joint effort between academic and governmental institutions from Brazil and Australia. The collaboration includes the Federal University of Minas Gerais (UFMG) in Brazil, the University of Sydney and University of Melbourne in Australia, the Australian Twin Registry, as well as the research foundations CNPq and CAPES in Brazil. The BTR is a member of the International Network of Twin Registries. Recruitment strategies used to register twins have been through participation in a longitudinal study investigating genetic and environmental factors for low back pain occurrence, and from a variety of sources including media campaigns and social networking. Currently, 291 twins are registered in the BTR, with data on demographics, zygosity, anthropometrics, and health history having been collected from 151 twins using a standardized self-reported questionnaire. Future BTR plans include the registration of thousands of Brazilian twins identified from different sources and collaborate nationally and internationally with other research groups interested on twin studies.

Acute lateral ankle sprain (ALAS) is a common injury, but its treatment has yet to be firmly established. The purpose of this study was to investigate how Brazilian Orthopedists (including residents) manage the diagnosis, classification, treatment and complications of ALAS. Methods: A multiple-choice questionnaire was developed with the aim of addressing the main aspects of the treatment of ALAS. The questionnaire was made available on the official website of the Brazilian Society of Orthopedics and Traumatology between June 15 and August 1, 2004. Results: 444 questionnaires were included in the analysis. The results showed agreement among most of the interviewees in the following regards: 90.8% used a classification method to guide treatment of the sprain; 59% classified the ankle sprain with certainty; 63.7% used rigid immobilization in cases of totally torn ligaments; 60.6% used anti-inflammatory medication in cases of partial ligament tears; and 75.9% reported that residual pain was the most frequent complication. There was no consensus regarding the immobilization method for partial ALAS, given that immobilization and functional treatment were chosen with the same frequency (47%). There was no significant difference between the responses from residents and from orthopedists (p = 0.81). Conclusions: Orthopedists and orthopedic residents in Brazil have difficulty classifying ALAS and there is no consensus about the best therapeutic option for partial ALAS. PMID:27022596

This paper examines the role of the Technical Advisory Committee for antiretroviral therapy of the Brazilian AIDS program in mediating the decision-making process of including new antiretroviral (ARV) drugs in the Unified Health System services by the end of the 2000s. We conducted documental analysis and interviews with key informants from the governmental sphere and professionals. The work features the Technical Advisory Committee as an "expert community", defined as a network of individuals with expertise and competence in a particular sphere and whose knowledge is relevant in critical public policy decision areas. It also indicates that the decision-making process for inclusion of antiretroviral drugs in the Brazilian program was incremental, considering the expectations of the innovative leader companies of pharmaceutical market. The work describes thus the results of the interaction of government interests, pharmaceutical industry and experts in the implementation of a relevant international policy. It provides arguments and evidence for understanding the role of expert communities on a sectorial public policy so far analyzed predominantly from the perspective of social movements.

This study evaluated the indoor air quality in Brazilian universities by comparing thirty air-conditioned (AC) (n = 15) and naturally ventilated (NV) (n = 15) classrooms. The parameters of interest were indoor carbon dioxide (CO2), temperature, relative humidity (RH), wind speed, viable mold, and airborne dust levels. The NV rooms had larger concentration of mold than the AC rooms (1001.30 ± 125.16 and 367.00 ± 88.13 cfu/m3, respectively). The average indoor airborne dust concentration exceeded the Brazilian standards (<80 μg/m3) in both NV and AC classrooms. The levels of CO2 in the AC rooms were significantly different from the NV rooms (1433.62 ± 252.80 and 520.12 ± 37.25 ppm, respectively). The indoor air quality in Brazilian university classrooms affects the health of students. Therefore, indoor air pollution needs to be considered as an important public health problem. PMID:25019268

We analyzed the sociodemographic profile, migration journey, health conditions, and health care access and utilization among recent Haitian immigrants to the Brazilian Amazon state of Mato Grosso. We conducted a cross-sectional study with a probabilistic sample of 452 Haitians. We administered a bilingual questionnaire from December 2014 to February 2015. Data were analyzed using chi square tests to evaluate differences among groups. The majority of participants were married men younger than 35 years old. They mostly came from the Haiti's Artibonite Department, living in Brazil for less than a year. Half of the participants were employed at the time of the interviews, and 81.8% relied exclusively on the Brazilian Unified Healthcare System for medical care. The overall health profile and health care access were good. Haitian migration to Brasil is a case of South-South migration driven by economic needs. Our population had good health status despite socioeconomic challenges.

Clinical forensic examinations performed at the Institute of Legal Medicine of the Hanover Medical School between 1999 and 2008 in cases of suspected physical abuse of children were analyzed retrospectively with special emphasis on the legal consequences. Altogether, 192 children (85 girls, 107 boys) with a median age of 4.4 years were examined. In 47 cases (24.5 %), the clinical forensic examination findings were interpreted as accidental injuries, birth traumas or unspecific findings. 29 victims (20.0 %) had suffered a shaken baby syndrome. Only part of the presented cases ended with conviction, which was more likely if the victims were aged between 7 and 11 years. Prison terms of 2 years and more were imposed only if the child suffered potentially or acute life-threatening injuries or if additional anogenital lesions were diagnosed indicating sexual child abuse.

Malaria epidemiology in the Pakaanóva (Wari') Indians, Brazilian Amazon.

This paper reports the results of a longitudinal study of malaria incidence (1998-2002) among the Pakaanóva (Wari') Indians, Brazilian southwest Amazon region, based on data routinely gathered by Brazilian National Health Foundation outposts network in conjunction with the Indian health service. Malaria is present yearlong in the Pakaanóva. Statistically significant differences between seasons or months were not noticed. A total of 1933 cases of malaria were diagnosed in the Pakaanóva during this period. The P. vivax / P. falciparum ratio was 3.4. P. vivax accounted for 76.5% of the cases. Infections with P. malariae were not recorded. Incidence rates did not differ by sex. Most malaria cases were reported in children < 10 years old (45%). About one fourth of all cases were diagnosed on women 10-40 years old. An entomological survey carried out at two Pakaanóva villages yielded a total of 3.232 specimens of anophelines. Anopheles darlingi predominated (94.4%). Most specimens were captured outdoors and peak activity hours were noted at early evening and just before sunrise. It was observed that Pakaanóva cultural practices may facilitate outdoor exposure of individuals of both sexes and all age groups during peak hours of mosquito activities (e.g., coming to the river early in the morning for bathing or to draw water, fishing, engaging in hunting camps, etc). In a context in which anophelines are ubiquitous and predominantly exophilic, and humans of both sexes and all ages are prone to outdoor activities during peak mosquito activity hours, malaria is likely to remain endemic in the Pakaanóva, thus requiring the development of alternative control strategies that are culturally and ecologically sensitive.

The objective of this study was to describe the process of translation and cultural adaptation of the Brazilian version of the Neighborhood Environment Walkability Scale for Youth (NEWS-Y). The original and the Portuguese versions were independently translated and back-translated into English. An expert panel performed semantic analysis and conceptual adaptations. The translated version of the NEWS-Y was applied to a sample of eight adolescents and showed adequate understanding. After minor changes identified in the translation processes, the expert panel considered the Brazilian version of the NEWS-Y semantically and conceptually equivalent. The translated version of the NEWS-Y required a few adjustments to ensure conceptual, item, and semantic adaptation. Further studies are recommended to examine other steps in the cross-cultural adaptation of the Portuguese-language NEWS-Y version in the Brazilian context.

This research evaluates the influence of the Brazilian accreditation methodology on the sustainability of the organizations. Critical factors for implementing accreditation were also examined, including measuring the relationships established between these factors in the organization sustainability. The present study was developed based on the survey methodology applied in the organizations accredited by ONA (National Accreditation Organization); 288 responses were received from the top level managers. The analysis of quantitative data of the measurement models was made with factorial analysis from principal components. The final model was evaluated from the confirmatory factorial analysis and structural equation modeling techniques. The results from the research are vital for the definition of factors that interfere in the accreditation processes, providing a better understanding for accredited organizations and for Brazilian accreditation.

Associations between dietary patterns (DP) and socioeconomic factors have been little explored in adolescents. The aim of this study was to identify DP in European and Brazilian adolescents and to investigate their associations with a range of socioeconomic indicators. Adolescents from the HELENA-study and the Household Budget Survey were analyzed. Factor analysis was used to obtain DP. Linear regression was used to examine the association between DP and SES. In Europeans, the Western DP was associated with low education of the mother, high socioeconomic status (boys), older age (boys), and living in cities of the Northern Europe; in Brazilians, the Western DP was associated with high secondary education of the mother, high socioeconomic status and living in Southern areas of the country. The Traditional European DP, in both genders, was associated with high secondary education of the mother and inversely associated with a high socioeconomic status; the Traditional Brazilian DP, was associated with university level education of the mother and older age (boys). The association between DP and socioeconomic factors is relevant for the understanding of food-related practices and highlight the importance of performing a complete assessment of the socioeconomic influence in adolescent’s DP from developed and developing countries.

The relationship between enteropathogens and severe diarrhoea in the Brazilian Amazon is poorly understood. In 1998, outbreaks of acute diarrhoea clinically diagnosed as cholera occurred in two small villages localized far from the main cholera route in the Brazilian rainforest. PCR was performed on some enteropathogens and heat-labile (LT) and/or heat-stable (STh) toxin genes, the virulence determinants of enterotoxigenic Escherichia coli (ETEC), were detected. Further characterization of ETEC isolates revealed the presence of two clones, one from each outbreak. One presenting serotype O167:H5 harboured LT-I and STh toxin genes and expressed the CS5CS6 colonization factor. The other, a non-typeable serotype, was positive for the LT-I gene and expressed the CS7 colonization factor. The current study demonstrates the importance of molecular diagnosis in regions such as the Amazon basin, where the enormous distances and local support conditions make standard laboratory diagnosis difficult. Here we also show that the mis-identified cholera cases were in fact associated with ETEC strains. This is the first report of ETEC, molecularly characterized as the aetiological agent of severe diarrhoea in children and adults in the Brazilian Amazon Rainforest.

The guidelines on allergic rhinitis aim to update knowledge about the disease and care for affected patients. The initiative called "Allergic Rhinitis and its Impact on Asthma", initially published in 2001 and updated in 2008 and 2010, has been very successful in disseminating information and evidence, as well as providing a classification of severity and proposing a systemized treatment protocol. In order to include the participation of other medical professionals in the treatment of allergic rhinitis, it is important to develop algorithms that accurately indicate what should and can be done regionally. To update the III Brazilian Consensus on Rhinitis - 2012, with the creation of an algorithm for allergic rhinitis management. We invited 24 experts nominated by the Brazilian Association of Allergy and Immunology, Brazilian Association of Otorhinolaryngology and Head and Neck Surgery and Brazilian Society of Pediatrics to update the 2012 document. The update of the last Brazilian Consensus on Rhinitis incorporated and adapted the relevant information published in all "Allergic Rhinitis and its Impact on Asthma" Initiative documents to the Brazilian scenario, bringing new concepts such as local allergic rhinitis, new drugs and treatment evaluation methods. A flowchart for allergic rhinitis treatment has been proposed. Copyright © 2017. Published by Elsevier Editora Ltda.

The study Pesquisa Dimensões Sociais das Desigualdades (PDSD) (Social Dimensions of Inequalities) involves 12,423 randomly selected Brazilian men and women aged 18 years old or more from urban and rural areas of the five Brazilian regions, and the information collected included the SF-36 as a measure of health-related quality of life. This provided a unique opportunity to develop age and gender-adjusted normative data for the Brazilian population. Brazilian men scored substantially higher than women on all eight domains and the two summary component scales of the SF-36. Brazilians scored less than their international counterparts on almost all of SF-36 domains and both summary component scales, except on general health status (US), pain (UK) and vitality (Australia, US and Canada). The differences in the SF-36 scores between age groups, genders and countries confirm that these Brazilian norms are necessary for comparative purposes. The data will be useful for assessing the health status of the general population and of patient populations, and the effect of interventions on health-related quality of life.

The scope of this study was to analyze how the International Sanitary Regulation (ISR 2005)has been incorporated into the Brazilian legal-administrative system, in relation to sanitary control measures involving freight, means of transportation and travelers and possible alterations to health surveillance activities, competencies and procedures. This case study has been undertaken using a qualitative approach, of a descriptive and exploratory nature, using institutional data sources and interviews with key-informants involved in implementing ISR (2005). Alterations to the Brazilian legal-administrative system resulting from ISR (2005) were identified, in relation to standards, special competencies and procedures relating to sanitary controls for freight, modes of transportation and travelers. In its present form, the International Sanitary Regulation is an instrument that, in addition to introducing new international and national sanitary control concepts and elements, also helps to clarify questions that are helpful on a national level, relating to the specific competencies and procedures which will, to a certain extent, put pressure on administrative structures in the areas of sanitary control and surveillance.

Many studies point to a possible new stylized fact for financial time series: the multifractality. Several authors have already detected this characteristic in multiple time series in several countries. With that in mind and based on Multifractal Detrended Fluctuation Analysis (MFDFA) method, this paper analyzes the multifractality in the Brazilian market. This analysis is performed with daily data from IBOVESPA index (Brazilian stock exchange's main index) and other four highly marketable stocks in the Brazilian market (VALE5, ITUB4, BBDC4 and CIEL3), which represent more than 25% of the index composition, making up 1961 observations for each asset in the period from June 26 2009 to May 31 2017. We found that the studied stock prices and Brazilian index are multifractal, but that the multifractality degree is not the same for all the assets. The use of shuffled and surrogated series indicates that for the period and the actions considered the long-range correlations do not strongly influence the multifractality, but the distribution (fat tails) exerts a possible influence on IBOVESPA and CIEL3.

Inflammatory disorders are common in modern life, and medicinal plants provide an interesting source for new compounds bearing anti-inflammatory properties. In this regard, Brazilian medicinal plants are considered to be a promising supply of such compounds due to their great biodiversity. To undertake a review on Brazilian medicinal plants with corroborated anti-inflammatory activities by selecting data from the literature reporting the efficacy of plants used in folk medicine as anti-inflammatory, including the mechanisms of action of their extracts and isolated compounds. A search in the literature was undertaken by using the following Web tools: Web of Science, SciFinder, Pub-Med and Science Direct. The terms 'anti-inflammatory' and 'Brazilian medicinal plants' were used as keywords in search engine. Tropicos and Reflora websites were used to verify the origin of the plants, and only the native plants of Brazil were included in this review. The publications reporting the use of well-accepted scientific protocols to corroborate the anti-inflammatory activities of Brazilian medicinal plants with anti-inflammatory potential were considered. We selected 70 Brazilian medicinal plants with anti-inflammatory activity. The plants were grouped according to their anti-inflammatory mechanisms of action. The main mechanisms involved inflammatory mediators, such as interleukins (ILs), nuclear factor kappa B (NF-κB), prostaglandin E2 (PGE2), cyclooxygenase (COX) and reactive oxygen species (ROS). The collected data on Brazilian medicinal plants, in the form of crude extract and/or isolated compounds, showed significant anti-inflammatory activities involving different mechanisms of action, indicating Brazilian plants as an important source of anti-inflammatory compounds.

2013-11-01

Policies for scientific development and knowledge production in health have increased in recent decades. In Brazil, incentives for research, development, and innovation have been part of the National Health Act since 1990, and science and technology policies for health, including health technology assessment (HTA), have been implemented since 1994, as in many other countries. The emphasis is now on impact evaluation of HTA policies in the incorporation of technologies by health services and systems. The article presents a case study of HTA utilization in decision-making processes in the Brazilian Ministry of Health, analyzing participation by the Department of Science and Technology (DECIT), responsible for the production of assessments used in the Commission on Technology Incorporation (CITEC) of the Ministry of Health from 2008 to 2010. CITEC used 103 assessments in its decisions during this period, of which DECIT produced 80%. Nearly all were literature reviews on therapeutic technologies. An increase in knowledge production was observed. A methodological and political learning process appears to have occurred in the use of HTA, but its impact on Brazilian Unified National Health System remains unclear.

This study was aimed at verifying the prevalence of nutritive (breast-feeding and bottle-feeding) and non-nutritive sucking habits and the presence of malocclusion in Brazilian preschool children. The study was a cross-sectional oral health survey of 342 children (196 boys and 146 girls) between the ages of 3 and 5 in Campina Grande, Brazil. The data was collected by interviews with the children's mothers or minders and by clinical examinations carried out by a calibrated examiner (kappa = 0,86). Descriptive statistics using the EPI-INFO Program (version 3.3) and Chi-square test at 0.05 probability level were produced. Sucking habit prevalence was very high in all groups, ranging from 70 % to 77,4 %. Malocclusion was present in 87 %, dummy use in 84,8 % and finger-sucking in 7,2 %. About 84,2 % of the children had a history of bottle-feeding and 79,9 % showed some evidence of malocclusion at the time of dental examination. There were significant differences for the following variables: sucking habits and malocclusion; breast-feeding time and sucking habits; breast-feeding time and malocclusion; type of feeding and sucking habits; and type of feeding and malocclusion. Dummy-sucking incidence was higher than that of finger-sucking in Brazilian children. Sucking habit incidence was higher in bottle-fed children than in breast-fed children. The relationship between incidence of habits and malocclusion was statistically significant.

2018-02-01

This population-based longitudinal study investigated the incidence, progression and risk factors for dental erosion among South Brazilian adolescents. Eight hundred and one schoolchildren attending 42 public and private schools were clinically examined at 12 years of age; clinical examinations were repeated after 2.5 years (SD=0.3). After tooth cleaning and drying, permanent incisors and first molars were classified using the Basic Erosive Wear Examination (BEWE) scoring criteria. Questionnaires were used to collect data on socio-demographic characteristics, dietary habits, toothbrushing frequency and general health. Poisson regression analysis was used to assess the association between dental erosion incidence and explanatory variables, with adjusted incidence risk ratios (IRR) and 95% CI estimated. Among those who did not have dental erosion at baseline, 49 of 680 schoolchildren (7.1%; 95% CI=5.2-9.1) developed erosive lesions over the follow-up period. Among schoolchildren who had dental erosion at baseline, 31 of 121 (25.4%; 95% CI=17.6-33.3) had new or more severe lesions. Boys were more likely to develop dental erosion than girls (IRR=1.88; 95% CI=1.06-3.32). A moderate incidence of dental erosion was observed among South Brazilian adolescents, with boys being at higher risk. The high progression rate of 25% observed here is very concerning, and it should be taken in consideration when designing preventive strategies for dental erosion. © 2017 John Wiley & Sons A/S.

By means of scientometric indicators, this study investigated the characteristics of scientific production and research collaboration involving zebrafish (Danio rerio) in Brazilian Science indexed by the Web of Science (WoS). Citation data were collected from the WoS and data regarding Impact Factor (IF) were gathered from journals in the Journal Citation Reports. Collaboration was evaluated according to coauthorship data, creating representative nets with VOSviewer. Zebrafish has attained remarkable importance as an experimental model organism in recent years and an increase in scientific production with zebrafish is observed in Brazil and around the world. The citation impact of the worldwide scientific production is superior when compared to the Brazilian scientific production. However, the citation impact of the Brazilian scientific production is consistently increasing. Brazil does not follow the international trends with regard to publication research fields. The state of Rio Grande do Sul has the greatest number of articles and the institution with the largest number of publications is Pontifícia Universidade Católica do Rio Grande do Sul. Journals' average IF is higher in Brazilian publications with international coauthorship, and around 90% of articles are collaborative. The Brazilian institutions presenting the greatest number of collaborations are Pontifícia Universidade Católica do Rio Grande do Sul, Universidade Federal do Rio Grande do Sul, Fundação Universidade Federal de Rio Grande, and Universidade de São Paulo. These data indicate that Brazilian research using zebrafish presents a growth in terms of number of publications, citation impact, and collaborative work.

We aimed to retrospectively compare the prevalence of soft tissue calcifications (STCs) depicted incidentally along the extra- and intracranial course of the internal carotid artery (ICA) on cone beam computed tomography examinations in 2 different populations (Greeks and Brazilians). The cohort consisted of examinations of 232 Greeks and 174 Brazilians, for a total of 406 patients. The scans were evaluated for the presence of STCs along the course of the ICA, with data analyzed in each ethnic group according to gender and age criteria. In total, 355 STCs were recorded; 78 (22.0% of all STCs) and 58 (16.3%) were extracranials, and 128 (36.1%) and 91 (25.6%) were intracranials for Greeks and Brazilians, respectively. The χ(2) test indicated no statistical differences between Greeks and Brazilians in the occurrence of STCs; however, their prevalence differed between genders in those populations. The presence of lesions, both extra- and intracranially, was found to increase with age (P < .05). The odds ratios were estimated at 2.23 (95% CI, 1.81-2.74) and 3.26 (95% CI, 2.56-4.16) for extracranial and intracranial lesions, respectively, with increasing age. We found an equal distribution for both extra- and intracranial STCs among Greeks and Brazilians. The prevalence of lesions differed between genders within both populations. Aging was found to be a risk factor for STCs, as the odds ratio increased significantly. Copyright © 2016 Elsevier Inc. All rights reserved.

The Value of Outsourcing Selected Cases in a Medical Examiner Population: A 10-Year Experience.

Due to increasing caseloads and inadequate staffing, the burden on Coroner/Medical Examiner Offices to comply with recommended autopsy limits for forensic pathologists (FPs) has been difficult. Since 2006, pathologists at the University of Alabama at Birmingham have performed select autopsies for the Alabama Department of Forensic Sciences. Each case was reviewed by a state FP and scene investigator to determine appropriateness for referral. All referred cases received full postmortem examination including microscopic examination and collection of toxicological samples, and toxicology was ordered by the referring FP as appropriate. The final cause and manner of death were determined by the referring state FP after review of all findings. A majority of the 421 cases were ruled accidental deaths (233), most due to drug toxicity. Of the 178 natural deaths, 118 were attributed to cardiovascular disease. Outsourcing select forensic cases can be educational and an effective tool to manage workflow without compromising quality. © 2016 American Academy of Forensic Sciences.

2011-01-01

This article provides an ethnographic analysis of Afro-Brazilian religious responses to the HIV epidemic in Recife. Drawing on participant observation and in-depth interviews conducted with Afro-Brazilian religious leaders and public health officials, it highlights the importance of the axé--a mystical energy manipulated in religious rituals that is symbolically associated with blood, sweat and semen. In an analysis of the relationship formed between the state AIDS programme and Afro-Brazilian religious centres, we conclude that the recognition of native categories and their meanings is one of the key elements to a fruitful dialogue between public health programmes and religious leaders that in the case studied, resulted in the re-signification of cultural practices to prevent HIV. Although the Afro-Brazilian religious leaders interviewed tended to be more open about sexuality and condom promotion, stigma towards people living with HIV (PLHIV) was still present within the religious temples, yet appeared to be more centred upon the perception of HIV as negatively affecting followers' axé than judgement related to how one may have contracted the virus. We discuss the tensions between taking a more liberal and open stance on prevention, while also fostering attitudes that may stigmatise PLHIV, and make suggestions for improving the current Afro-Brazilian response to the epidemic.

The internet has proven to be a valuable resource for self-care, allowing access to information and promoting interaction between professionals, caregivers, users of health care services and people interested in health information. However, recurring searches are often related to excessive health anxiety and a phenomenon known as cyberchondria can have impacts on physical and mental health. Within this background, a Cyberchondria Severity Scale has been developed to differentiate healthy and unhealthy behavior in internet searches for health information, based on the following criteria: compulsion, distress, excesses, and trust and distrust of health professionals. To conduct cross-cultural adaptation of the Cyberchondria Severity Scale for Brazilian Portuguese, because of the lack of an appropriate instrument for Brazil. This study was authorized by the original author of the scale. The process was divided into the following four steps: 1) initial translation, 2) back-translation, 3) development of a synthesized version, and 4) experimental application. Translation into Brazilian Portuguese required some idiomatic expressions to be adapted. In some cases, words were not literally translated from English into Portuguese. Only items 7, 8, 12, 23 and 27 were altered, as a means of both conforming to proper grammar conventions and achieving easy comprehension. The items were rewritten without loss of the original content. This paper presents a translated version of the Cyberchondria Severity Scale that has been semantically adapted for the Brazilian population, providing a basis for future studies in this area, which should in turn contribute to improved understanding of the cyberchondria phenomenon in this population.

This work was undertaken to ascertain to what degree the physical appearance of a Brazilian individual was predictive of genomic African ancestry. Using a panel of 10 population-specific alleles, we assigned to each person an African ancestry index (AAI). The procedure was able to tell apart, with no overlaps, 20 males from northern Portugal from 20 males from São Tomé Island on the west coast of Africa. We also tested 10 Brazilian Amerindians and observed that their AAI values fell in the same range as the Europeans. Finally, we studied two different Brazilian population samples. The first consisted of 173 individuals from a rural Southeastern community, clinically classified according to their Color (white, black, or intermediate) with a multivariate evaluation based on skin pigmentation in the medial part of the arm, hair color and texture, and the shape of the nose and lips. In contrast to the clear-cut results with the African and European samples, our results showed large variances and extensive overlaps among the three Color categories. We next embarked on a study of 200 unrelated Brazilian white males who originated from cosmopolitan centers of the four major geographic regions of the country. The results showed AAI values intermediate between Europeans and Africans, even in southern Brazil, a region predominantly peopled by European immigrants. Our data suggest that in Brazil, at an individual level, color, as determined by physical evaluation, is a poor predictor of genomic African ancestry, estimated by molecular markers. PMID:12509516

Brazilian jiu-jitsu is characterized by musculoskeletal disorders and high occurrence of sports injuries. The present study was aimed to analyze some internal factors, as well as to describe occurrence and characteristics of retrospective musculoskeletal injuries in different age groups of Brazilian jiu-jitsu practitioners. One hundred ninety-three Brazilian jiu-jitsu practitioners, which were divided into three age groups: Adolescent, Adult, and Master. Besides anthropometric characterization, standard clinical tests were conducted to analyze the global and segmental joint flexibility, lumbar spine range of motion, and handgrip strength. Sports injury occurrence and total physical activity were obtained from an adapted morbidity survey and International Physical Activity Questionnaire - Short Form (IPAQ-SF), respectively. A total of 247 cases of retrospective injuries was registered (1.27 injury/ participant). Occurrence of rectus femoral muscle retraction in the right leg was increased within Master. Adult and Master have exhibited higher occurrence of sports injuries than Adolescent group ( p  < 0.05). Joint injuries were the most common sports-related injuries by all Brazilian jiu-jitsu practitioners. While female gender and exposure time constituted the most predictive variables for sports injury occurrence in Adolescent, graduation level was more associated with sports injuries occurrence in Adult. Joint injuries derived from combat demands were the main sports injury in all age categories of Brazilian jiu-jitsu. Master subjects presented a higher occurrence of clinical changes and retrospective musculoskeletal injuries in relation to other age groups. Female gender and exposure time constituted the main predictive factors in adolescent subjects, while graduation category was more directly associated with retrospective injury onset in the Adult group.

Objectives Healthcare leaders around the world are calling for radical, transformational change of our health and care systems. This will be a difficult and complex task. In this article, we examine case studies in which transformational change has been achieved, and seek to learn from these experiences. Methods We used the case study method to investigate examples of transformational change in healthcare. The case studies were identified from preliminary doctoral research into the transition towards future sustainable health and social care systems. Evidence was collected from multiple sources, key features of each case study were displayed in a matrix and thematic analysis was conducted. The results are presented in narrative form. Results Four case studies were selected: two from the US, one from Australia and one from the UK. The notable features are discussed for each case study. There were many common factors: a well communicated vision, innovative redesign, extensive consultation and engagement with staff and patients, performance management, automated information management and high-quality leadership. Conclusions Although there were some notable differences between the case studies, overall the characteristics of success were similar and collectively provide a blueprint for transformational change in healthcare. What is known about the topic? Healthcare leaders around the world are calling for radical redesign of our systems in order to meet the challenges of modern society. What does this paper add? There are some remarkable examples of transformational change in healthcare. The key factors in success are similar across the case studies. What are the implications for practitioners? Collectively, these key factors can guide future attempts at transformational change in healthcare.

The infectious origin of fatal cases of calf pneumonia was studied in 48 calves from 27 different herds on postmortem examination. Lung tissue samples were examined by pathological, histological, bacterial culture, virus isolation and immunohistochemical methods for the detection of viral and bacterial infections. Pneumonia was diagnosed in 47/48 cases and infectious agents were found in 40/47 (85%) of those cases. The presence of multiple respiratory pathogens in 23/40 (57.5%) cases indicated the complex origin of fatal calf pneumonia. The most important respiratory pathogens were Mannheimia-Pasteurella in 36/40 (90%) cases, followed by Arcanobacterium pyogenes in 16/40 (40%) cases, Mycoplasma bovis in 12/40 (30%) cases, and bovine respiratory syncytial virus in 4/40 (10%) cases. Histophilus somni was detected in 2/40 (5%) cases, while bovine herpesvirus-1, bovine viral diarrhoea virus and parainfluenza virus-3 were each found in 1/40 (2.5%) case. Mastadenovirus, bovine coronavirus, influenza A virus or Chlamydiaceae were not detected.

Isoniazid (INH), one of the most important drugs used in antituberculosis (anti-TB) treatment, is also the major drug involved in hepatotoxicity. Differences in INH-induced toxicity have been attributed to genetic variability at several loci, such as NAT2, CYP2E1, GSTM1 and GSTT1, that code for drug-metabolising enzymes. Our goal was to examine the polymorphisms in these enzymes as susceptibility factors to anti-TB drug-induced hepatitis in Brazilian individuals. In a case-control design, 167 unrelated active tuberculosis patients from the University Hospital of the Federal University of Rio de Janeiro, Brazil, were enrolled in this study. Patients with a history of anti-TB drug-induced acute hepatitis (cases with an increase to 3 times the upper limit of normal serum transaminases and symptoms of hepatitis) and patients with no evidence of anti-TB hepatic side effects (controls) were genotyped for NAT2, CYP2E1, GSTM1 and GSTT1 polymorphisms. Slow acetylators had a higher incidence of hepatitis than intermediate/rapid acetylators [22% (18/82) vs. 9.8% (6/61), odds ratio (OR), 2.86, 95% confidence interval (CI), 1.06-7.68, p = 0.04). Logistic regression showed that slow acetylation status was the only independent risk factor (OR 3.59, 95% CI, 2.53-4.64, p = 0.02) for the occurrence of anti-TB drug-induced hepatitis during anti-TB treatment with INH-containing schemes in Brazilian individuals.

Mother's milk is the primary source of nourishment in early infancy. When this source is unavailable, secondary sources may be used, such as human milk banks. The first milk bank in Brazil was created in 1943, and they have been used ever since. A national model was developed through a number of phases, culminating in the Brazilian Network of Human Milk Banks. This gave rise to a number of international cooperation projects, with the Brazilian model particularly relevant for developing nations. The main objective of this analysis is to understand what drives Brazil to promote milk banks internationally. To do this we tried to understand the relationship between health and foreign policy, expressed here as soft power, as here the two areas dialog with one another. The results include gains in both areas and the affirmation of health as a central goal of the national interest cluster of the case.

Objective To detect the presence and concentration of methylparaben in cartridges of commercial Brazilian local anesthetics. Material and methods Twelve commercial brands (4 in glass and 8 in plastic cartridges) of local anesthetic solutions for use in dentistry were purchased from the Brazilian market and analyzed. Different lots of the commercial brands were obtained in different Brazilian cities (Piracicaba, Campinas and São Paulo). Separation was performed using high performance liquid chromatography (HPLC) with UV-Vis detector. The mobile phase used was acetonitrile:water (75:25 - v/v), pH 4.5, adjusted with acetic acid at a flow rate of 1.0 ml.min-1. Results When detected in the solutions, the methylparaben concentration ranged from 0.01% (m/v) to 0.16% (m/v). One glass and all plastic cartridges presented methylparaben. Conclusion 1. Methylparaben concentration varied among solutions from different manufacturers, and it was not indicated in the drug package inserts; 2. Since the presence of methylparaben in dental anesthetics is not regulated by the Brazilian National Health Surveillance Agency (ANVISA) and this substance could cause allergic reactions, it is important to alert dentists about its possible presence.

Since the first position statement on diabetes and cardiovascular prevention published in 2014 by the Brazilian Diabetes Society, the current view on primary and secondary prevention in diabetes has evolved as a result of new approaches on cardiovascular risk stratification, new cholesterol lowering drugs, and new anti-hyperglycemic drugs. Importantly, a pattern of risk heterogeneity has emerged, showing that not all diabetic patients are at high or very high risk. In fact, most younger patients who have no overt cardiovascular risk factors may be more adequately classified as being at intermediate or even low cardiovascular risk. Thus, there is a need for cardiovascular risk stratification in patients with diabetes. The present panel reviews the best current evidence and proposes a practical risk-based approach on treatment for patients with diabetes. The Brazilian Diabetes Society, the Brazilian Society of Cardiology, and the Brazilian Endocrinology and Metabolism Society gathered to form an expert panel including 28 cardiologists and endocrinologists to review the best available evidence and to draft up-to-date an evidence-based guideline with practical recommendations for risk stratification and prevention of cardiovascular disease in diabetes. The guideline includes 59 recommendations covering: (1) the impact of new anti-hyperglycemic drugs and new lipid lowering drugs on cardiovascular risk; (2) a guide to statin use, including new definitions of LDL-cholesterol and in non-HDL-cholesterol targets; (3) evaluation of silent myocardial ischemia and subclinical atherosclerosis in patients with diabetes; (4) hypertension treatment; and (5) the use of antiplatelet therapy. Diabetes is a heterogeneous disease. Although cardiovascular risk is increased in most patients, those without risk factors or evidence of sub-clinical atherosclerosis are at a lower risk. Optimal management must rely on an approach that will cover both cardiovascular disease prevention in

Brazilian research on extremophiles in the context of astrobiology

Duarte, Rubens T. D.; Nóbrega, Felipe; Nakayama, Cristina R.; Pellizari, Vivian H.

2012-10-01

Extremophiles are organisms adapted to grow at extreme ranges of environmental variables, such as high or low temperatures, acid or alkaline medium, high salt concentration, high pressures and so forth. Most extremophiles are micro-organisms that belong to the Archaea and Bacteria domains, and are widely spread across the world, which include the polar regions, volcanoes, deserts, deep oceanic sediments, hydrothermal vents, hypersaline lakes, acid and alkaline water bodies, and other extreme environments considered hostile to human life. Despite the tropical climate, Brazil has a wide range of ecosystems which include some permanent or seasonally extreme environments. For example, the Cerrado is a biome with very low soil pH with high Al+3 concentration, the mangroves in the Brazilian coast are anaerobic and saline, Pantanal has thousands of alkaline-saline lakes, the Caatinga arid and hot soils and the deep sea sediments in the Brazilian ocean shelf. These environments harbour extremophilic organisms that, coupled with the high natural biodiversity in Brazil, could be explored for different purposes. However, only a few projects in Brazil intended to study the extremophiles. In the frame of astrobiology, for example, these organisms could provide important models for defining the limits of life and hypothesize about life outside Earth. Brazilian microbiologists have, however, studied the extremophilic micro-organisms inhabiting non-Brazilian environments, such as the Antarctic continent. The experience and previous results obtained from the Brazilian Antarctic Program (PROANTAR) provide important results that are directly related to astrobiology. This article is a brief synopsis of the Brazilian experience in researching extremophiles, indicating the most important results related to astrobiology and some future perspectives in this area.

Environmental news: coverage of the Earth Summit by Brazilian newspapers.

This article examines how two important Brazilian newspapers (Floha de S. Paulo and O Globo) covered the UN Conference on Environment and Development (UNCED) or Earth Summit. The analysis will also determine the characteristics of the environmental media and its significance when it comes to coverage of environmental issues. This article provides historical background information on the environmental media in the US and in Brazil, contextual information on the Earth Summit, a content analysis of stories about UNCED published by the two Brazilian newspapers. Overall, 649 news items were used to determine the type of sources used, as well as the kind of issues covered. The analysis showed that government officials were the most frequently cited sources, while environmentalists and scientists were all but ignored as news sources. The analysis also indicated that economic issues were surprisingly prominent in the coverage. These results are compatible with the previous studies done in several countries and indicate that environmental media are still extremely reliant on "official" voices. The finding also highlight the fact that the range of issues covered by the environmental media largely reflects the perceived public agenda.

Since 1988, Brazil's Unified Health System has sought to provide universal and equal access to immunisations. Inequalities in immunisation may be examined by contrasting vaccination coverage among children in the highest versus the lowest socioeconomic strata. The authors examined coverage with routine infant immunisations from a survey of Brazilian children according to socioeconomic stratum of residence census tract. The authors conducted a household cluster survey in census tracts systematically selected from five socioeconomic strata, according to average household income and head of household education, in 26 Brazilian capitals and the federal district. The authors calculated coverage with recommended vaccinations among children until 18 months of age, according to socioeconomic quintile of residence census tract, and examined factors associated with incomplete vaccination. Among 17,295 children with immunisation cards, 14,538 (82.6%) had received all recommended vaccinations by 18 months of age. Among children residing in census tracts in the highest socioeconomic stratum, 77.2% were completely immunised by 18 months of age versus 81.2%-86.2% of children residing in the four census tract quintiles with lower socioeconomic indicators (p<0.01). Census tracts in the highest socioeconomic quintile had significantly lower coverage for bacille Calmette-Guérin, oral polio and hepatitis B vaccines than those with lower socioeconomic indicators. In multivariable analysis, higher birth order and residing in the highest socioeconomic quintile were associated with incomplete vaccination. After adjusting for interaction between socioeconomic strata of residence census tract and household wealth index, only birth order remained significant. Evidence from Brazilian capitals shows success in achieving high immunisation coverage among poorer children. Strategies are needed to reach children in wealthier areas.

Within the context of reforming the judicial system, the aim of this study was to examine whether individual characteristics and working conditions influenced reports of sick leave amongst a population of Brazilian magistrates. A web-based survey was conducted in 2011 in such a way as to reach the entire population of Brazilian Labor-law magistrates across the country. The variable of interest related to the question: "Have you taken any medical leave due to illness over the last 12 months?" Less than a quarter of the population participated in the survey, despite widespread publicity produced by the professional association. Among the work-related factors, experiences of violence in the courthouse were shown to be associated with the outcome. No significant association with the material or psychosocial working conditions or with the workload was found. Female, worse health assessment, not participating in social activities and having a mother with higher schooling level were significantly associated with absenteeism among the magistrates. It is desirable to formulate sectorial policies focusing on controlling and monitoring violent events in the courthouse.

Haemosporidian blood parasites of the Plasmodium genus are the causative agents of avian malaria in many parts of the world. Despite the great diversity of Brazilian avifauna, few studies have been conducted to examine the haemosporidians of wild birds found in the Brazilian Atlantic Forest, especially those kept in captivity. This study aimed to re-examine and further characterize the South American avian parasite Plasmodium paranucleophilum using a multidisciplinary approach. Blood samples were collected from 68 captive birds representing 15 species found in the Atlantic Forest of southeastern Brazil. Morphometric and morphological characterization was performed, in addition to PCR and sequencing of the mitochondrial cytochrome b gene and subsequent phylogenetic analysis. The overall prevalence of P. paranucleophilum infection in the study was 13.23% (n = 9), with a mean parasitemia of 0.58%. We observed the highest parasitemia of 3.88% in Rupornis magnirostris. In our phylogenetic analysis, P. paranucleophilum and P lasmodium nucleophilum formed distinct, highly supported clades, with a mean genetic divergence of 2.48%. This study provides new morphological and molecular data, expanding our knowledge of the haemosporidians of wild birds in Brazil and highlighting the need for further investigation. The true depth of diversity in Brazilian avian haemosporidians remains largely unknown, and given the enormous variety of vectors and avian species, there may be many more species of these blood parasites yet to be described.

BACKGROUND Staging scales for dementia have been devised for grading Alzheimer's disease (AD) but do not include the specific symptoms of frontotemporal lobar degeneration (FTLD). OBJECTIVE To translate and adapt the Frontotemporal Dementia Rating Scale (FTD-FRS) to Brazilian Portuguese. METHODS The cross-cultural adaptation process consisted of the following steps: translation, back-translation (prepared by independent translators), discussion with specialists, and development of a final version after minor adjustments. A pilot application was carried out with 12 patients diagnosed with bvFTD and 11 with AD, matched for disease severity (CDR=1.0). The evaluation protocol included: Addenbrooke's Cognitive Examination-Revised (ACE-R), Mini-Mental State Examination (MMSE), Executive Interview (EXIT-25), Neuropsychiatric Inventory (NPI), Frontotemporal Dementia Rating Scale (FTD-FRS) and Clinical Dementia Rating scale (CDR). RESULTS The Brazilian version of the FTD-FRS seemed appropriate for use in this country. Preliminary results revealed greater levels of disability in bvFTD than in AD patients (bvFTD: 25% mild, 50% moderate and 25% severe; AD: 36.36% mild, 63.64% moderate). It appears that the CDR underrates disease severity in bvFTD since a relevant proportion of patients rated as having mild dementia (CDR=1.0) in fact had moderate or severe levels of disability according to the FTD-FRS. CONCLUSION The Brazilian version of the FTD-FRS seems suitable to aid staging and determining disease progression. PMID:29213863

The purpose of this study was to assess the characteristics and prevalence of sports-related injuries in visually disabled athletes of the Brazilian football 5-a-side team. The participants were 13 male athletes, all classified as B1 visual class, members of the Brazilian team, who played in five consecutive international competitions. Data were collected using the Brazilian Paralympic Committee and the Brazilian Confederation of Sports for the Blind report form. From the total of 13 athletes, 11 succumbed to some form of injury during the 5 competitions, which incorporated 23 matches, representing a prevalence of 84.6%. A total of 35 sports injuries were recorded, giving a clinical incidence of 2.7 injuries per athlete and an injury risk of 0.85 and an incidence rate of 0.12 injuries per match. Traumatic injuries (80%) were more common than overuse injuries (20%) (p<0.05). The highest distribution of injury was in the lower limbs (80%), followed by the head (8.6%), spine (5.7%) and upper limbs (5.7%). The body regions most affected were the knee (28.6%), feet (17.1%), ankle (11.4%) and thigh (11.4%). Contusions (31.4%), sprains (25.7%) and tendinopathy (8.6%) were the most frequent diagnoses. This is the first study to describe the nature and prevalence of sports-related injuries in 5-a-side football in blind athletes. The results are important in guiding strategies to inform the implementation of preventive pathways and provide a strong rationale for the compulsory use of additional protective equipment. © Georg Thieme Verlag KG Stuttgart · New York.

The Brazilian Societies of Rheumatology (SBR) and Dermatology (SBD), the Brazilian Federation of Gastroenterology (FBG) and the Brazilian Study Group on Inflammatory Bowel Disease (GEDIIB) gathered a group of their respective specialists on the topic of interest to discuss the most relevant issues regarding the clinical use of biosimilar medicines in Brazil. The main aim of that meeting was to prepare a document with recommendations to guide medical specialists and to help the national regulatory and policy-making agencies as concerns the authorization for marketing biosimilars used in autoimmune diseases, such as rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, Crohn's disease, juvenile idiopathic arthritis and ulcerative colitis. In addition to considerations on the typical differences between innovator medicines and biosimilars, the specialists established a set of seven recommendations on regulatory advances related to clinical studies, indication extrapolation, nomenclature, interchangeability, automatic substitution and pharmacovigilance.

The Brazilian population was formed by extensive admixture of three different ancestral roots: Amerindians, Europeans and Africans. Our previous work has shown that at an individual level, ancestry, as estimated using molecular markers, was a poor predictor of color in Brazilians. We now investigate if SNPs known to be associated with human skin pigmentation can be used to predict color in Brazilians. For that, we studied the association of fifteen SNPs, previously known to be linked with skin color, in 243 unrelated Brazilian individuals self-identified as White, Browns or Blacks from Rio de Janeiro and 212 unrelated Brazilian individuals self-identified as White or Blacks from São Paulo. The significance of association of SNP genotypes with self-assessed color was evaluated using partial regression analysis. After controlling for ancestry estimates as covariates, only four SNPs remained significantly associated with skin pigmentation: rs1426654 and rs2555364 within SLC24A5, rs16891982 at SLC45A2 and rs1042602 at TYR. These loci are known to be involved in melanin synthesis or transport of melanosomes. We found that neither genotypes of these SNPs, nor their combination with biogeographical ancestry in principal component analysis, could predict self-assessed color in Brazilians at an individual level. However, significant correlations did emerge at group level, demonstrating that even though elements other than skin, eye and hair pigmentation do influence self-assessed color in Brazilians, the sociological act of self-classification is still substantially dependent of genotype at these four SNPs.

The screening value of the comprehensive review of systems and the complete physical examination in detecting unsuspected diseases for which therapeutic interventions are initiated has not been formally studied in ambulatory patients. The medical records of 100 randomly selected adult patients who had an ambulatory general medical evaluation at the Mayo Clinic in 1990-1991 were surveyed to compare review of systems and physical examination with routine laboratory tests, chest radiography, and electrocardiography as case-finding maneuvers. The main outcome measure was the therapeutic yield of each case-finding maneuver, defined as the proportion of maneuvers leading to a new therapy for a new clinically important diagnosis. The utilization rate of routine tests in the 100 patients (mean age: 59 +/- 16 years; 58% women) was high, ranging from 77 to 98%. Overall, the case-finding maneuvers led to 36 unsuspected clinically important diagnoses and resulted in 25 new therapeutic interventions. Higher therapeutic yield was observed for review of systems (7%), physical examination (5%), and lipid screening (9.2%) than for chemistry group (2.2%), complete blood count (1.8%), thyroid tests (1.5%), urinalysis (1.1%), electrocardiography (0%), or chest radiography (0%). The number of therapeutic interventions was not associated with patient's age (P = 0.55), sex (P = 0.88), comorbidity (P = 0.30) or with the time interval since the last general medical evaluation (P = 0.12). Based on therapeutic yield, these data suggest that review of systems and physical examination are valuable case-finding maneuvers in the periodic medical evaluation of ambulatory patients.

Climate Change, Impacts and Vulnerabilities in Brazil: Preparing the Brazilian Northeast for the Future; Natal, Brazil, 27 May to 01 June 2012 The variability of the semiarid climate of the Brazilian northeast has enormous environmental and social implications. Because most of the population in this area depends on subsistence agriculture, periods of severe drought in the past have caused extreme poverty and subsequent migration to urban centers. From the ecological point of view, frequent and prolonged droughts can lead to the desertification of large areas. Understanding the causes of rainfall variability, in particular periods of severe drought, is crucial for accurate forecasting, mitigation, and adaptation in this important region of Brazil.

In this article, we present the Brazilian Portuguese Lexicon, a new word-based corpus for psycholinguistic and computational linguistic research in Brazilian Portuguese. We describe the corpus development, the specific characteristics on the internet site and database for user access. We also perform distributional analyses of the corpus and comparisons to other current databases. Our main objective was to provide a large, reliable, and useful word-based corpus with a dynamic, easy-to-use, and intuitive interface with free internet access for word and word-criteria searches. We used the Núcleo Interinstitucional de Linguística Computacional’s corpus as the basic data source and developed the Brazilian Portuguese Lexicon by deriving and adding metalinguistic and psycholinguistic information about Brazilian Portuguese words. We obtained a final corpus with more than 30 million word tokens, 215 thousand word types and 25 categories of information about each word. This corpus was made available on the internet via a free-access site with two search engines: a simple search and a complex search. The simple engine basically searches for a list of words, while the complex engine accepts all types of criteria in the corpus categories. The output result presents all entries found in the corpus with the criteria specified in the input search and can be downloaded as a.csv file. We created a module in the results that delivers basic statistics about each search. The Brazilian Portuguese Lexicon also provides a pseudoword engine and specific tools for linguistic and statistical analysis. Therefore, the Brazilian Portuguese Lexicon is a convenient instrument for stimulus search, selection, control, and manipulation in psycholinguistic experiments, as also it is a powerful database for computational linguistics research and language modeling related to lexicon distribution, functioning, and behavior.

Adiponectin is an important mediator of insulin sensitivity, encoded by the ADIPOQ gene. Here we describe two Japanese-Brazilian families with hypoadiponectinaemia due to a novel mutation in ADIPOQ. In this study, we examined the entire translated regions of adiponectin in Japanese-Brazilians, a population with one of the highest prevalence rates of diabetes worldwide. We screened 200 patients with type 2 diabetes (DM) and 240 age-matched subjects with normal glucose tolerance. A novel heterozygous T deletion at position 186 in exon 2 of ADIPOQ, causing a frameshift at codon 62 and leading to a premature termination at codon 168 (p.Gly63ValfsX106), was found in two individuals with diabetes. This mutation was not found in 240 nondiabetic control subjects. In addition, we screened the mutation in an expanded set of 100 nondiabetic subjects from the general Brazilian population, but we found no mutations. In addition, six family members of the probands were identified as mutation-carriers. Individuals who were mutation-carriers had markedly low plasma adiponectin concentrations compared with those without the mutation [DM: 0.65 (0.59-1.34) microg/ml vs. 5.30 (3.10-8.55) microg/ml, P < 0.0001; normal glucose tolerance: 0.95 (0.76-1.48) microg/ml vs. 8.50 (5.52-14.55) microg/ml, P = 0.003]. All individuals carrying the p.Gly63ValfsX106 mutation and older than 30 years were found to be diabetic. We describe for the first time a frameshift mutation in exon 2 of the ADIPOQ gene, which modulates adiponectin levels and may contribute to the genetic risk of late-onset diabetes in Japanese-Brazilians.

Plasticity of illusory vowel perception in Brazilian-Japanese bilinguals.

2010-06-01

Previous research shows that monolingual Japanese and Brazilian Portuguese listeners perceive illusory vowels (/u/ and /i/, respectively) within illegal sequences of consonants. Here, several populations of Japanese-Brazilian bilinguals are tested, using an explicit vowel identification task (experiment 1), and an implicit categorization and sequence recall task (experiment 2). Overall, second-generation immigrants, who first acquired Japanese at home and Brazilian during childhood (after age 4) showed a typical Brazilian pattern of result (and so did simultaneous bilinguals, who were exposed to both languages from birth on). In contrast, late bilinguals, who acquired their second language in adulthood, exhibited a pattern corresponding to their native language. In addition, an influence of the second language was observed in the explicit task of Exp. 1, but not in the implicit task used in Exp. 2, suggesting that second language experience affects mostly explicit or metalinguistic skills. These results are compared to other studies of phonological representations in adopted children or immigrants, and discussed in relation to the role of age of acquisition and sociolinguistic factors.

We investigated whether self-reported ethnic discrimination in the workplace was associated with well-being among Japanese Brazilians who had returned to Japan. Further, we examined interactions between discrimination and education on well-being. We obtained data from a cross-sectional survey of Japanese Brazilian workers (n = 313) conducted in 2000 and 2001. Outcomes were self-rated health, psychological symptoms as measured by the 12-item General Health Questionnaire (GHQ-12) score, and a checklist of somatic symptoms. Reports of ethnic discrimination were associated with increased risk of poor self-rated health and psychological symptoms (GHQ-12 score), after we controlled for self-assessed workload, supportive relations at work, physically dangerous working conditions, workplace environmental hazards, shift work, number of working hours, age, gender, marital status, income, education, Japanese lineage, length of residence, and Japanese language proficiency. Further, the relationship between discrimination and self-rated health and somatic symptoms was most robust for those with the least education. Ethnic discrimination appears to be a correlate of morbidity among Japanese Brazilian migrants. Future research should investigate how educational and workplace interventions may reduce discrimination and possibly improve health.

Among the main factors that affect patients' quality of life, fatigue is a significant symptom experienced by children during treatment. Despite the high incidence, there has been no validated scale to evaluate fatigue in children with cancer in Brazil. The purpose of this study was to examine the psychometric properties of the PedsQL™ Multidimensional Fatigue Scale, using self-reports of Brazilian children, 8 to 18 years of age, and proxy reports. A cross-sectional method was used to collect data from 216 subjects over an 18-month period. Reliability ranged from .70 to .90 except for sleep/rest fatigue, self-report (α = .55). No floor or ceiling effects were found in any dimension. Convergent validity was higher than .40 and divergent validity had 100% adjustment. The root mean square error of approximation was acceptable. The comparative fit index was lower than expected. The agreement between self and proxy responses was weak and moderate. The results demonstrate the reliability and validity of the Brazilian version in children with cancer. This is the first validated scale that assesses fatigue in Brazilian children and adolescents with cancer. © 2014 by Association of Pediatric Hematology/Oncology Nurses.

Blood, sweat and semen: The economy of axé and the response of Afro-Brazilian religions to HIV and AIDS in Recife

2011-01-01

This article provides an ethnographic analysis of Afro-Brazilian religious responses to the HIV epidemic in Recife. Drawing on participant observation and in-depth interviews conducted with Afro-Brazilian religious leaders and public health officials, it highlights the importance of the axé – a mystical energy manipulated in religious rituals that is symbolically associated with blood, sweat, and semen. In an analysis of the relationship formed between the state AIDS programme and Afro-Brazilian religious centres, we conclude that the recognition of native categories and their meanings is one of the key elements to a fruitful dialogue between public health programmes and religious leaders that in the case studied, resulted in the re-signification of cultural practices to prevent HIV. Although the Afro-Brazilian religious leaders interviewed tended to be more open about sexuality and condom promotion, stigma towards people living with HIV (PLHIV) was still present within the religious temples, yet appeared to be more centred upon the perception of HIV as negatively affecting followers’ axé than judgment related to how one may have contracted the virus. We discuss the tensions between taking a more liberal and open stance on prevention, while also fostering attitudes that may stigmatise PLHIV, and make suggestions for improving the current Afro-Brazilian response to the epidemic.

Ten years of Brazilian ballast water management

In 2005, Brazil addressed the environmental challenges posed by ballast water through a unilateral regulation, called the Maritime Standard N° 20 (NORMAM-20), applied to all shipping in her waters. This world-leading decision was the culmination of a process that started during the 1990‧s. Here, we summarize how these ballast water regulations were brought in and adopted and present the findings of 10 years of enforcement (2005-2015) in 39 ports along the Brazilian coast. We show that compliance with the Brazilian standard has increased significantly since the regulations were implemented (p < 0.001). After five years of implementation, non-compliance decreased probably reflecting an increase in awareness of the Brazilian Standard and a shift in the shipping industry commitment to minimize and control the spread of invasive species through ballast water. The Brazilian experience shows that very high levels (97%) of compliance with ballast water management regulations can be made to work in a region of global importance to the maritime industry. In the last decade, the rules governing ballast water in Brazil have evolved to address the demands from the maritime community and to provide updates such as imminent requirements for the use of ballast water management systems on board ships. These regulations are rarely cited when ballast water regulations are discussed internationally, yet there is much to learn from the proactive approach taken by Brazil such as what is feasible and enforceable.

A slurry sampling electrothermal atomic absorption spectrometric method is proposed for the determination of trace elements such as Cu, Cr, Cd and Pb in yogurt. The main factors affecting the slurry preparation were optimized: nature and concentration of acid solution and sonication time. The analytical method was validated in-house by calibration, linearity, limits of detection and quantification, precision and accuracy test obtaining satisfactory results in all cases. The proposed method was applied for the determination of Cd, Cr, Cu and Pb in some Brazilian yogurt samples. For these samples, the concentrations ranged from 2.5±0.2 to 12.4±0.2ngg -1 ; 34±3 to 899±7ngg -1 ; <8.3 to 12±1ngg -1 ; and <35.4 to 210±16ngg -1 for Cd, Cu, Cr and Pb, respectively. The daily intake of Cd, Cu, Cr and Pb via consumption of these samples was estimated. Copyright © 2017 Elsevier Ltd. All rights reserved.

The number of elderly people in Brazil has increased during the last few decades. Oral lesions are very common in this age group, but few studies have examined the prevalence of these conditions worldwide and, particularly, in Brazil. This study aimed to evaluate the frequency of oral lesions in an elderly Brazilian population. A total of 534 cases of oral lesions retrieved from the files of the Oral Pathology Laboratory of the School of Dentistry, University of Pernambuco, between 1991 and 2008, were descriptively and qualitatively evaluated. In this study, the oral mucosal lesions cases preferentially affected women (n=357; 66.8%), white persons (n=253; 47.3%), in the seventh decade of life (n=361; 67.6%), and with lesions predominantly located on the gingival/alveolar ridge (n=102; 19.1%). The non-neoplastic lesions (n=353; 66.1%) were more prevalent than benign neoplasms (n=85; 15.9%), oral cancers (n=56; 10.4%) and potentially malignant lesions (n=40; 7.4%). The five most predominant diseases were fibrous hyperplasia, non-specific chronic inflammatory processes, oral squamous cell carcinoma, non-specified odontogenic cysts and epithelial dysplasia. Our results may be helpful in understanding the distribution of oral diseases in this very specific age group that requires special attention. © 2010 The Authors.

The primary and secondary feathers of 170 Brazilian psittacine birds (Aves: Psittaciformes) were examined in order to identify feather quill mite fauna. Birds were held captive in two locations in the state of Minas Gerais (MG), and two in the state of Espirito Santo (ES). The quills were cut longitudinally and were examined under optical microscopy. The genus of quill mites most frequently found was Paralgopsis (Astigmata: Pyrogliphidae), followed by Cystoidosoma (Astigmata: Syringobiidae). Astigmata: Syringophilidae mites were sporadically observed. After analyzing the data using logistic regression models, it was determined that there was higher infestation risk for psittacines in ES state, as compared with those in MG, and a significant increase in risk depending on the psittacine host species. However, the location of captivity did not have a significant effect. Lesions were observed in infested feathers. Cystoidosoma sp. and Paralgopsis sp. were always observed together, with parts of Paralgopsis found inside Cystoidosoma sp., suggesting thanatochresis or predation.

Climatically-mediated landcover change: impacts on Brazilian territory.

In the face of climate change threats, governments are drawing attention to policies for mitigating its effects on biodiversity. However, the lack of distribution data makes predictions at species level a difficult task, mainly in regions of higher biodiversity. To overcome this problem, we use native landcover as a surrogate biodiversity, because it can represent specialized habitat for species, and investigate the effects of future climate change on Brazilian biomes. We characterize the climatic niches of native landcover and use ecological niche modeling to predict the potential distribution under current and future climate scenarios. Our results highlight expansion of the distribution of open vegetation and the contraction of closed forests. Drier Brazilian biomes, like Caatinga and Cerrado, are predicted to expand their distributions, being the most resistant to climate change impacts. However, these would also be affected by losses of their closed forest enclaves and their habitat-specific or endemic species. Replacement by open vegetation and overall reductions are a considerable risk for closed forest, threatening Amazon and Atlantic forest biomes. Here, we evidence the impacts of climate change on Brazilian biomes, and draw attention to the necessity for management and attenuation plans to guarantee the future of Brazilian biodiversity.

We report here the first complete mitochondria genome of Onchocerca volvulus from a focus outside of Africa. An O. volvulus mitogenome from the Brazilian Amazonia focus was obtained using a combination of high-throughput and Sanger sequencing technologies. Comparisons made between this mitochondrial genome and publicly available mitochondrial sequences identified 46 variant nucleotide positions and suggested that our Brazilian mitogenome is more closely related to Cameroon-origin mitochondria than West African-origin mitochondria. As well as providing insights into the origins of Latin American onchocerciasis, the Brazilian Amazonia focus mitogenome may also have value as an epidemiological resource.

The Health Service Quality Scale is a multidimensional hierarchical scale that is based on interdisciplinary approach. This instrument was specifically created for measuring health service quality based on marketing and health care concepts. The aim of this study was to translate and culturally adapt the Health Service Quality Scale into Brazilian Portuguese and to assess the validity and reliability of the Brazilian Portuguese version of the instrument. We conducted a cross-sectional, observational study, with public health system patients in a Brazilian university hospital. Validity was assessed using Pearson's correlation coefficient to measure the strength of the association between the Brazilian Portuguese version of the instrument and the SERVQUAL scale. Internal consistency was evaluated using Cronbach's alpha coefficient; the intraclass (ICC) and Pearson's correlation coefficients were used for test-retest reliability. One hundred and sixteen consecutive postoperative patients completed the questionnaire. Pearson's correlation coefficient for validity was 0.20. Cronbach's alpha for the first and second administrations of the final version of the instrument were 0.982 and 0.986, respectively. For test-retest reliability, Pearson's correlation coefficient was 0.89 and ICC was 0.90. The culturally adapted, Brazilian Portuguese version of the Health Service Quality Scale is a valid and reliable instrument to measure health service quality.

the objective of this study was to describe the frequency of cystic lesions in a Brazilian population of patients histopathologically diagnosed in the first and second decade of life. Retrospective descriptive cross-sectional study was performed. Biopsy records were obtained from the archives of a Brazilian referral center between 1980 and 2016. A total of 2.114 biopsy records of pediatric patients were analyzed with oral and maxillofacial lesions. Data such as gender, age, anatomical location, and histopathological diagnosis were collected and categorized. Among all oral and maxillofacial lesions (n=2.114), were diagnosed 294 cases of odontogenic cysts (13.9%) and 16 cases of non-odontogenic cysts (0.8%). The most frequent lesions in each group were, respectively: radicular cyst (n=145) and epidermoid cyst (n=4). These lesions were most common in female (n=158), with a mean age of 14 years. For intraosseous lesions, the mandible (n=148) was the most affected anatomic site; moreover, the floor of the mouth (n=6) was most affected by cysts in soft tissues. Odontogenic cysts were relatively common in population studied, but non-odontogenic cysts were rare in these patients.

2006-05-01

The objective of this paper is to present and discuss Brazilian policy concerning actions to protect breastfeeding, especially the history, international and national background, limitations, and perspectives of the Brazilian Guidelines for the Marketing of Baby Food, Pacifiers and Bottles. The Brazilian Guidelines, which play a crucial role in protecting breastfeeding against industry marketing strategies, were based on the International Code of Marketing of Breastmilk Substitutes, proposed by the World Health Organization in 1981. The first version of the Brazilian Guidelines was released in 1988, and there were subsequent revisions in 1992 and 2001/2002. In 2006, the Guidelines became national law. However, the strides made over this period in terms of regulation have been few because the law is not always observed. Thus, it is essential that all actors involved, including government officials, manufacturers and sellers of baby food and other baby products, teaching and health professionals and their associations, international bodies, and non-governmental organizations make a commitment to enforce the current law.

This study aimed to verify the biological efficiency and production flushes of Agaricus blazei strains on different casing layers during 90 cultivation days. Four casing layers were used: mixture of subsoil and charcoal (VCS), lime schist (LSC), São Paulo peat (SPP) and Santa Catarina peat (SCP); and two genetically distant A. blazei strains. The fungus was grown in composted substratum and, after total colonization, a pasteurized casing layer was added over the substratum, and fructification was induced. Mushrooms were picked up daily when the basidiocarp veil was stretched, but before the lamella were exposed. The biological efficiency (BE) was determined by the fresh basidiocarp mass divided by the substratum dry mass, expressed in percentage. The production flushes were also determined over time production. The BE and production flushes during 90 days were affected by the strains as well as by the casing layers. The ABL26 and LSC produced the best BE of 60.4%. Although VCS is the most used casing layer in Brazil, it is inferior to other casing layers, for all strains, throughout cultivation time. The strain, not the casing layer, is responsible for eventual variations of the average mushroom mass. In average, circa 50% of the mushroom production occurs around the first month, 30% in the second month, and 20% in third month. The casing layer water management depends on the casing layer type and the strain. Production flush responds better to water reposition, mainly with ABL26, and better porosity to LSC and SCP casing layers. PMID:24031673

We have performed observations of the sky alongside with the Indians of all Brazilian regions that made it possible localize many indigenous constellations. Some of these constellations are the same as the other South American Indians and Australian aborigines constellations. The scientific community does not have much of this information, which may be lost in one or two generations. In this work, we present a planetary-observatory that we have made in the Park of Science Newton Freire-Maia of Paraná State, in order to popularize the astronomical knowledge of the Brazilian Indians. The planetary consists, essentially, of a sphere of six meters in diameter and a projection cylinder of indigenous constellations. In this planetary we can identify a lot of constellations that we have gotten from the Brazilian Indians; for instance, the four seasonal constellations: the Tapir (spring), the Old Man (summer), the Deer (autumn) and the Rhea (winter). A two-meter height wooden staff that is posted vertically on the horizontal ground similar to a Gnomon and stones aligned with the cardinal points and the soltices directions constitutes the observatory. A stone circle of ten meters in diameter surrounds the staff and the aligned stones. During the day we observe the Sun apparent motions and at night the indigenous constellations. Due to the great community interest in our work, we are designing an itinerant indigenous planetary-observatory to be used in other cities mainly by indigenous and primary schools teachers.

The current study investigated the correlation between anthropometric indicators and sleep quality among Brazilian university students using the Pittsburgh Sleep Quality Index. A cross-sectional assessment with 702 university students was conducted between March 2010 and June 2011. Results showed that cases of obesity were more frequent among students who were good sleepers. On the other hand, overweight and high cervical and abdominal circumference was most prominent among poor sleepers. Thus, apart from the damage caused by sleep disorders alone, additional risks due to the association between poor sleep quality and being overweight, central obesity, and increased cervical perimeter are highlighted.

To investigate the inter-rater and intra-rater reliability, construct validity and internal consistency of the Brazilian version of the Nottingham Sensory Assessment for Stroke Patients (NSA). The instrument was translated into Portuguese from its original in English by a bilingual translator and was then back-translated into English. Twenty-one hemiparetics were evaluated by two examiners using the NSA and the Fugl-Meyer Assessment (FMA) of physical performance. Significant correlation were found between the FMA and the NSA (r=0.752). The NSA showed excellent internal consistency (0.86), and there were acceptable inter- and intra-rater reliability for all items of the NSA, except temperature. Significant ceiling effects were found for the NSA and the FMA. The Brazilian version of the NSA met the criteria for agreement, internal consistency and concurrent validity. It was quick and easy to apply, and it could be used within clinical practice in neuro-rehabilitation outpatient clinics to assess sensory functions following stroke. The significant ceiling effect for the NSA did not limit its use, given that for the same patients, the FMA also showed ceiling effects.

Brazilian version of the Jefferson Scale of Empathy: psychometric properties and factor analysis

2012-01-01

Background Empathy is a central characteristic of medical professionalism and has recently gained attention in medical education research. The Jefferson Scale of Empathy is the most commonly used measure of empathy worldwide, and to date it has been translated in 39 languages. This study aimed to adapt the Jefferson Scale of Empathy to the Brazilian culture and to test its reliability and validity among Brazilian medical students. Methods The Portuguese version of the Jefferson Scale of Empathy was adapted to Brazil using back-translation techniques. This version was pretested among 39 fifth-year medical students in September 2010. During the final fifth- and sixth-year Objective Structured Clinical Examination (October 2011), 319 students were invited to respond to the scale anonymously. Cronbach’s alpha, exploratory factor analysis, item-total correlation, and gender comparisons were performed to check the reliability and validity of the scale. Results The student response rate was 93.7% (299 students). Cronbach’s coefficient for the scale was 0.84. A principal component analysis confirmed the construct validity of the scale for three main factors: Compassionate Care (first factor), Ability to Stand in the Patient’s Shoes (second factor), and Perspective Taking (third factor). Gender comparisons did not reveal differences in the scores between female and male students. Conclusions The adapted Brazilian version of the Jefferson Scale of Empathy proved to be a valid, reliable instrument for use in national and cross-cultural studies in medical education.

War, Medicine, and Cultural Diplomacy in the Americas: Frank Wilson and Brazilian cardiology.

PubMed

Kropf, Simone P; Howell, Joel D

2017-10-01

American cultural diplomacy played a key role in the institutionalization of Brazilian cardiology. In 1942, Frank Wilson, an internationally recognized pioneer in electrocardiography, made an extended wartime visit to Rio de Janeiro and São Paulo. The visit was sponsored by the United States Department of State as part of Roosevelt's Good Neighbor Policy and brought Wilson together with a group of physicians who would establish the specialty of cardiology in Brazil. This US cultural and diplomatic initiative strengthened an academic network that was already evolving and would eventually prove to be of benefit to both sides. Latin American physicians began in the 1920s to visit Wilson's laboratory at the University of Michigan, where they established the relationships on which Wilson would build. While affiliation with the "Wilson school" advanced the cause of Brazilian cardiologists who sought to establish themselves as specialists, cooperation with Latin American physicians benefitted Wilson in his pursuit of wider recognition for his innovations in the use of electrocardiography (ECG). Wilson's identity as a scientific ambassador to Latin America helped in legitimating his approach to the clinical application of the ECG. A close examination of Wilson's relationship to Brazilian cardiology demonstrates the role played by science and medicine as a part of wartime cultural diplomacy, as well as the dynamics of the transnational circulation of scientific knowledge and practices. © The Author 2017.

Assess the epidemiological aspects of tuberculosis in Brazilian indigenous children and actions to control it. An epidemiological study was performed with 356 children from 0 to 14 years of age in Rondônia State, Amazon, Brazil, during the period 1997-2006. Cases of TB reported to the Notifiable Diseases Surveillance System were divided into indigenous and non-indigenous categories and analyzed according to sex, age group, place of residence, clinical form, diagnostic tests and treatment outcome. A descriptive analysis of cases and hypothesis test (χ²) was carried out to verify if there were differences in the proportions of illness between the groups investigated. A total of 356 TB cases were identified (125 indigenous, 231 non-indigenous) of which 51.4% of the cases were in males. In the indigenous group, 60.8% of the cases presented in children aged 0-4 years old. The incidence mean was much higher among indigenous; in 2001, 1,047.9 cases/100,000 inhabitants were reported in children aged < 5 years. Pulmonary TB was reported in more than 80% of the cases, and in both groups over 70% of the cases were cured. Cultures and histopathological exams were performed on only 10% of the patients. There were 3 cases of TB/HIV co-infection in the non-indigenous group and none in the indigenous group. The case detection rate was classified as insufficient or fair in more than 80% of the indigenous population notifications, revealing that most of the diagnoses were performed based on chest x-ray. The approach used in this study proved useful in demonstrating inequalities in health between indigenous and non-indigenous populations and was superior to the conventional analyses performed by the surveillance services, drawing attention to the need to improve childhood TB diagnosis among the indigenous population.

Exclusive breastfeeding for the first 6 months of life and timely introduction of appropriate solid foods are important determinants of weight status in infancy and later life stages. Disparities in obesity rates among young children suggest that maternal feeding practices during the first 2 years of life may contribute to these disparities. Brazilians are a growing immigrant group in the United States, yet little research has focused on parental beliefs and behaviors affecting the health of Brazilian immigrant children in the United States. Research aim: This study aimed to explore beliefs and infant-feeding practices of Brazilian immigrant mothers in the United States. Focus group discussions were conducted with Brazilian immigrant mothers. Transcripts were analyzed using thematic analysis and themes categorized using the socioecological model. Twenty-nine immigrant Brazilian mothers participated in the study. Analyses revealed that all participants breastfed their infants. The majority initiated breastfeeding soon after childbirth. However, most mothers did not exclusively breastfeed. They used formula and human milk concomitantly. Family and culture influenced mothers' infant-feeding beliefs and practices in early introduction of solid foods. As the number of children in the United States growing up in families of immigrant parents increases, understanding influences on Brazilian immigrant mothers' infant-feeding practices will be important to the development of effective interventions to promote healthy infant feeding and weight status among Brazilian children. Interventions designed for Brazilian immigrant families should incorporate an understanding of social context, family, and cultural factors to develop health promotion messages tailored to the needs of this ethnic group.

The aims of the current study were 1) to evaluate the reliability and validity of the Brazilian version of the 15-item Myasthenia Gravis Quality of Life Scale and 2) to investigate the quality of life of Brazilian patients with myasthenia gravis and its determinants. This cross-sectional study included 69 patients with myasthenia gravis who underwent neurological evaluation and completed questionnaires regarding quality of life (the 36-item Short Form of the Medical Outcomes Study and the 15-item Myasthenia Gravis Quality of Life Scale), anxiety and depressive symptoms. The Brazilian version of the 15-item Myasthenia Gravis Quality of Life Scale showed high internal consistency and good concurrent validity with the 36-item Short Form of the Medical Outcomes Study and its subscales. Determinants of quality of life in Brazilian patients with myasthenia gravis included the current status of myasthenia gravis as assessed by the Myasthenia Gravis Composite, the current prednisone dose and the levels of anxiety and depression. The Brazilian version of the 15-item Myasthenia Gravis Quality of Life Scale is a valid instrument. Symptom severity, prednisone dosage and anxiety and depression levels impact the quality of life of patients with myasthenia gravis.

PXR polymorphisms have been implicated in modulating CYP3A4 and PXR expression, potentially accounting for interindividual differences in drug metabolism. The prevalence of PXR polymorphisms varies among ethnic groups and data on the allelic distribution in the highly mixed Brazilian population is lacking. The aim of this study was to analyze genetic variations in the PXR gene in Brazilians and to compare the results to other ethnic groups. DNA samples from 117 healthy Brazilians underwent PCR amplification and sequencing. Eleven polymorphisms were identified, 3 of which are highly associated with differences in CYP3A4 expression. We also identified 1 new synonymous variant in 1.3% of the alleles. Among the functional polymorphisms, -25913 C>T and -6994T>C occurred at a higher frequency comparedtothe Africanalleles (p < 0.05) but at a lower frequency compared to Caucasian alleles. The 8055 C>T allele was found at a similar frequency to those described in Caucasians and Africans (p > 0.05). We observed that functional variants of the PXR were frequent in our sample of the Brazilian population. Our results suggest that PXR gene variants may be of interest in pharmacogenetic studies involving Brazilians.

Allelic patterns and genetic distances were examined in a collection of 103 foreign and Brazilian mango (Mangifera indica) accessions in order to develop a reference database to support cultivar protection and breeding programs. An UPGMA dendrogram was generated using Jaccard's coefficients from a distance matrix based on 50 alleles of 12 microsatellite loci. The base pair number was estimated by the method of inverse mobility. The cophenetic correlation was 0.8. The accessions had a coefficient of similarity from 30 to 100%, which reflects high genetic variability. Three groups were observed in the UPGMA dendrogram; the first group was formed predominantly by foreign accessions, the second group was formed by Brazilian accessions, and the Dashehari accession was isolated from the others. The 50 microsatellite alleles did not separate all 103 accessions, indicating that there are duplicates in this mango collection. These 12 microsatellites need to be validated in order to establish a reliable set to identify mango cultivars.

Depression is a common contributor to suffering and disability in people with chronic pain. However, the assessment of depression in this population has been hampered by the presence of a number of somatic symptoms that are shared between chronic pain, treatment side-effects and traditional concepts of depression. As a result, the use of depression measures that do not contain somatic items has been encouraged. This study examined the psychometric properties of the Depression sub-scale of the Depression Anxiety and Stress Scales (DASS) in a Brazilian chronic pain patient population. Data on a number of measures were collected from 348 participants attending pain facilities. Principal components and exploratory factor analyses indicated the presence of only one factor. Item analyses indicated adequate item-scale correlations. The Cronbach alpha was .96, which suggests an excellent internal consistency. The DASS-Depression scale has adequate psychometric properties and its further use with Brazilian chronic pain populations can now be supported.

Brazilian purpuric fever (BPF) is a recently recognized fulminant pediatric disease characterized by fever, with rapid progression to purpura, hypotensive shock, and death. BPF is usually preceded by purulent conjunctivitis that has resolved before the onset of fever. Both the conjunctivitis and BPF are caused by Haemophilus influenzae biogroup aegyptius (formerly called H. aegyptius). Isolates from 15 BPF cases, mainly from blood or hemorrhagic cerebrospinal fluid, case-associated isolates from 42 persons in towns where BPF cases occurred, and control strains from 32 persons in towns without BPF cases were characterized biochemically, genetically, and epidemiologically. Results indicated that a single clone was responsible for all BPF cases identified in six Brazilian towns from 1984 through 1986. All of 15 (100%) case strains were the same clone as was 1 of 32 (3%) control strains (P = less than 10(-8). Isolates of the clone were preferentially intrarelated by DNA hybridization (99% relatedness, hydroxyapatite method at 60 and 75 degrees C) and were separable from other H. influenzae biogroup aegyptius strains (approximately 90% relatedness at 60 degrees C and 82% relatedness at 75 degrees C). All isolates of the BPF clone and no other strains contained a 24-megadalton plasmid of restriction endonuclease type 3031, were of a single multilocus enzyme mobility type, were of a single sodium dodecyl sulfate-polyacrylamide gel electrophoresis type, and were in one of two ribosomal DNA restriction patterns. All BPF clone isolates reacted with monoclonal antibodies produced from a case strain; only 3 of 62 (5%) other strains reacted with this monoclonal antibody. Ninety percent of BPF clone strains and 27% of other strains were relatively resistant to sulfamethoxazole-trimethoprim. Images PMID:3262623

It has been reported that a work environment that does not support nurses, and high levels of emotional exhaustion and job dissatisfaction are associated with nurses' intent to leave their job. The aim of this study was to determine if these work-related factors and job-related outcomes are common in Brazilian nurses. This cross-sectional study included a 2015 survey of nursing professionals who worked in 48 units of three Brazilian, acute care hospitals. Descriptive statistics were used to examine the sample and a series of logistic regression models were fit to examine two job-related outcomes of interest: job dissatisfaction and intent to leave during the next 12 months. A total of 450 completed surveys were available, where nurses reported high emotional exhaustion (26%), job dissatisfaction (28%), and an intent to leave (12%). Poor control over the work environment (OR = 2.19) and high emotional exhaustion (OR = 4.47) were associated with an increase in the odds of job dissatisfaction. Inadequate staffing (OR = 2.43), high emotional exhaustion (OR = 2.24) and job dissatisfaction (OR = 5.74) were associated with an increase in the odds that nurses would leave their job in the next 12 months. Features of the nurse work environment and high emotional exhaustion were associated with job dissatisfaction. Job dissatisfaction and inadequate staffing are likely to result in nurses leaving their job. It is imperative that hospital administrators provide a work environment that supports nursing and improves nurse outcomes and the quality of patient care. Copyright © 2018 Elsevier Inc.

To test the hypothesis that malocclusion and its impact on quality of life has no effect on 8- to 10-year-old Brazilian schoolchildren as measured by an oral health-related quality of life (OHRQoL) instrument. A cross-sectional study was carried out with a population-based sample of 1204 8- to 10-year-old children attending elementary schools in Belo Horizonte, Brazil. Dental examinations were carried out by two calibrated examiners. OHRQoL was assessed using the Brazilian version of the Child Perceptions Questionnaire. The Dental Aesthetic Index was used for the clinical assessment of malocclusion. Dental caries and socioeconomic factors were used as controlling variables. Bivariate analysis involved the chi-square test and the Fisher exact test. A Poisson regression model was employed for the multivariate analysis (P < .05). Anterior segment spacing and anterior mandibular overjet were significantly associated with impact on OHRQoL (P < .05). Schoolchildren with malocclusion were 1.30-fold (95% CI: 1.15-1.46; P < 0.001) more likely to experience a negative impact on OHRQoL than those without malocclusion. Children belonging to families with an income less than or equal to two times the minimum wage were 1.59-fold (95% CI: 1.35-1.88; P < 0.001) more likely to experience a negative impact on OHRQoL than those belonging to families with the highest income. Schoolchildren with malocclusion from lower-income families experience a greater negative impact on OHRQoL.

Objective Investigating dimensions of oppositional symptoms may help to explain heterogeneity of etiology and outcomes for mental disorders across development and provide further empirical justification for the DSM-5–proposed modifications of oppositional defiant disorder (ODD). However, dimensions of oppositionality have not previously been tested in samples outside Europe or the United States. In this study, we used a large Brazilian community sample to compare the fit of different models for dimensions of oppositional symptoms; to examine the association of psychiatric diagnoses and symptoms with dimensions of oppositionality; and to examine the associations between dimensions of oppositionality and parental history of mental disorders. Method A Brazilian community sample of 2,512 children 6 through 12 years old were investigated in this study. Confirmatory factorial analyses were performed to compare the fit of alternative models, followed by linear and logistic regression analyses of associations with psychiatric diagnosis and parental history of psychopathology. Results A three-factor model with irritable, headstrong, and hurtful dimensions fitted best. The irritable dimension showed a strong association with emotional disorders in the child (p<.001) and history of depression (p<.01) and suicidality (p<.05) in the mother. The headstrong dimension was uniquely associated with attention-deficit/hyperactivity disorder (ADHD) in the child (p<.001) and with maternal history of ADHD symptoms (p<.05). The hurtful dimension was specifically associated with conduct disorder (p< .05). Conclusions Our findings from a large community sample of Brazilian children support a distinction between dimensions of oppositionality consistent with current DSM-5 recommendations and provide further evidence for etiological distinctions between these dimensions.

There are limited data regarding efavirenz pharmacogenetics in admixed populations. The Brazilian population is highly admixed. In a Brazilian cohort, we sought to characterize associations between efavirenz adverse effects (all-cause and CNS) and polymorphisms in seven genes known or suspected to affect efavirenz metabolism and transport. We studied 225 HIV-positive individuals who had been prescribed efavirenz-containing regimens at a hospital in Rio de Janeiro, Brazil. Eighty-nine cases had efavirenz adverse effects, including 43 with CNS adverse effects, while 136 controls had no adverse effect of any antiretroviral after treatment for at least 6 months. A total of 67 candidate polymorphisms in ABCB1, CYP2A6, CYP2B6, CYP3A4, CYP3A5, NR1I2 and NR1I3 genes were selected for association analysis. Admixture was assessed using 28 ancestry-informative polymorphisms previously validated for the Brazilian population. Associations were evaluated with logistic regression models adjusted for sex and genetic ancestry. There was extensive African, European and Native American admixture in the cohort. Increased all-cause adverse effects were associated with the CYP2B6 genotype combination 15582CC-516TT-983TT (OR = 7.26, P = 0.003) and with the CYP2B6 slow metabolizer group 516TT or 516GT-983CT (OR = 3.10, P = 0.04). CNS adverse effects were nominally associated with CYP3A4 rs4646437 (OR = 4.63, P = 0.014), but not after adjusting for multiple comparisons. In a highly admixed Brazilian cohort, the CYP2B6 slow metabolizer genotype was associated with an increased risk of efavirenz adverse effects.

A current concern in genetic epidemiology studies in admixed populations is that population stratification can lead to spurious results. The Brazilian census classifies individuals according to self-reported "color", but several studies have demonstrated that stratifying according to "color" is not a useful strategy to control for population structure, due to the dissociation between self-reported "color" and genomic ancestry. We report the results of a study in a group of Brazilian siblings in which we measured skin pigmentation using a reflectometer, and estimated genomic ancestry using 21 Ancestry Informative Markers (AIMs). Self-reported "color", according to the Brazilian census, was also available for each participant. This made it possible to evaluate the relationship between self-reported "color" and skin pigmentation, self-reported "color" and genomic ancestry, and skin pigmentation and genomic ancestry. We observed that, although there were significant differences between the three "color" groups in genomic ancestry and skin pigmentation, there was considerable dispersion within each group and substantial overlap between groups. We also saw that there was no good agreement between the "color" categories reported by each member of the sibling pair: 30 out of 86 sibling pairs reported different "color", and in some cases, the sibling reporting the darker "color" category had lighter skin pigmentation. Socioeconomic status was significantly associated with self-reported "color" and genomic ancestry in this sample. This and other studies show that subjective classifications based on self-reported "color", such as the one that is used in the Brazilian census, are inadequate to describe the population structure present in recently admixed populations. Finally, we observed that one of the AIMs included in the panel (rs1426654), which is located in the known pigmentation gene SLC24A5, was strongly associated with skin pigmentation in this sample.

Fire feedbacks facilitate invasion of pine savannas by Brazilian pepper (Schinus terebinthifolius).

* Fire disturbance can mediate the invasion of ecological communities by nonnative species. Nonnative plants that modify existing fire regimes may initiate a positive feedback that can facilitate their continued invasion. Fire-sensitive plants may successfully invade pyrogenic landscapes if they can inhibit fire in the landscape. * Here, we investigated whether the invasive shrub Brazilian pepper (Schinus terebinthifolius) can initiate a fire-suppression feedback in a fire-dependent pine savanna ecosystem in the southeastern USA. * We found that prescribed burns caused significant (30-45%) mortality of Brazilian pepper at low densities and that savannas with more frequent fires contained less Brazilian pepper. However, high densities of Brazilian pepper reduced fire temperature by up to 200 degrees C, and experienced as much as 80% lower mortality. * A cellular automaton model was used to demonstrate that frequent fire may control low-density populations, but that Brazilian pepper may reach a sufficient density during fire-free periods to initiate a positive feedback that reduces the frequency of fire and converts the savanna to an invasive-dominated forest.

Objective. To assess content and criterion validity, as well as reliability of an internally developed, case-based, cumulative, high-stakes third-year Annual Student Assessment and Progression Examination (P3 ASAP Exam). Methods. Content validity was assessed through the writing-reviewing process. Criterion validity was assessed by comparing student scores on the P3 ASAP Exam with the nationally validated Pharmacy Curriculum Outcomes Assessment (PCOA). Reliability was assessed with psychometric analysis comparing student performance over four years. Results. The P3 ASAP Exam showed content validity through representation of didactic courses and professional outcomes. Similar scores on the P3 ASAP Exam and PCOA with Pearson correlation coefficient established criterion validity. Consistent student performance using Kuder-Richardson coefficient (KR-20) since 2012 reflected reliability of the examination. Conclusion. Pharmacy schools can implement internally developed, high-stakes, cumulative progression examinations that are valid and reliable using a robust writing-reviewing process and psychometric analyses.

The lack of Brazilian norms restrains the use of the Alberta Infant Motor Scale (AIMS) to precisely categorize infant motor development and discriminate infants with motor difficulties from typically developing infants. This study investigated reference values for the AIMS for Brazilian infants. Descriptive, cross-sectional study of infants from birth-to-18 months old. Trained professionals assessed infants in daycares, homes, and governmental health centers. Results showed increases in raw scores across age groups from 0- to 15-months of age. The stability of raw scores was observed after 16 months of age. Brazilian infants demonstrated lower scores in specific ages compared to the Canadian sample. Canadian and Brazilian children showed differences in motor performance scores across age and norms were established for Brazilian infants. This study highlights the importance to establish reference values for AIMS of infants across cultures. Copyright © 2016 Elsevier Inc. All rights reserved.

Background Since 1988, Brazil's Unified Health System has sought to provide universal and equal access to immunisations. Inequalities in immunisation may be examined by contrasting vaccination coverage among children in the highest versus the lowest socioeconomic strata. The authors examined coverage with routine infant immunisations from a survey of Brazilian children according to socioeconomic stratum of residence census tract. Methods The authors conducted a household cluster survey in census tracts systematically selected from five socioeconomic strata, according to average household income and head of household education, in 26 Brazilian capitals and the federal district. The authors calculated coverage with recommended vaccinations among children until 18 months of age, according to socioeconomic quintile of residence census tract, and examined factors associated with incomplete vaccination. Results Among 17 295 children with immunisation cards, 14 538 (82.6%) had received all recommended vaccinations by 18 months of age. Among children residing in census tracts in the highest socioeconomic stratum, 77.2% were completely immunised by 18 months of age versus 81.2%–86.2% of children residing in the four census tract quintiles with lower socioeconomic indicators (p<0.01). Census tracts in the highest socioeconomic quintile had significantly lower coverage for bacille Calmette-Guérin, oral polio and hepatitis B vaccines than those with lower socioeconomic indicators. In multivariable analysis, higher birth order and residing in the highest socioeconomic quintile were associated with incomplete vaccination. After adjusting for interaction between socioeconomic strata of residence census tract and household wealth index, only birth order remained significant. Conclusions Evidence from Brazilian capitals shows success in achieving high immunisation coverage among poorer children. Strategies are needed to reach children in wealthier areas. PMID:22268129

Endoscopic sphincterotomy (EST) is considered as a possible etiological factor for severe cholangitis. We herein report a case of severe cholangitis after endoscopic sphincterotomy induced by barium examination. An adult male patient presented with epigastric pain was diagnosed as having choledocholithiasis by ultrasonography. EST was performed and the stone was completely cleaned. Barium examination was done 3 d after EST and severe cholangitis appeared 4 h later. The patient was recovered after treated with tienam for 4 d. Barium examination may induce severe cholangitis in patients after EST, although rare, barium examination should be chosen cautiously. Cautions should be also used when EST is performed in patients younger than 50 years to avoid the damage to the sphincter of Oddi. PMID:23112564

Wang, Xiangyu

2015-12-01

For coal mine ground control issues, it is necessary to propose a failure criteria accounting for the transversely isotropic behaviors of rocks. Hence, it is very helpful to provide experimental data for the validation of the failure criteria. In this paper, the method for preparing transversely isotropic specimens and the scheme of the Brazilian tensile strength test are presented. Results obtained from Brazilian split tests under dry and water-saturated conditions reflect the effect of the development direction β of the structural plane, such as the bedding fissure, on the tensile strength, ultimate displacement, failure mode, and the whole splitting process. The results show that the tensile strength decreases linearly with increasing β. The softening coefficient of the tensile strength shows a sinusoidal function. The values of the slope and inflection point for the curve vary at the different stages of the Brazilian test. The failure mode of the rock specimen presented in this paper generally coincides with the standard Brazilian splitting failure mode. Based on the test results, the major influencing factors for the Brazilian splitting strength are analyzed and a mathematical model for solving the Brazilian splitting strength is proposed. The findings in this paper would greatly benefit the coal mine ground control studies when the surrounding rocks of interest show severe transversely isotropic behaviors.

In recent years, Brazil has been the scene of international events, gaining worldwide repercussion. However, this increases the risk of terrorist attacks using chemical warfare agents. It brings the need to achieve proficiency to do a quick and unequivocal identification of these dangerous compounds. Thinking about it, the Laboratory of Chemical Analyzes (LAQ) of Brazilian Army has participated since the end of 2010 in the interlaboratory tests promoted by the Organisation for the Prohibition of Chemical Weapons (OPCW). In this article, we discuss about the participation of LAQ in the 40th OPCW Proficiency Test, one more step in the way to become a laboratory designated by OPCW and an international reference.

Fanconi anemia (FA) is a predominantly autosomal recessive disease with wide genetic heterogeneity resulting from mutations in several DNA repair pathway genes. To date, 21 genetic subtypes have been identified. We aimed to identify the FA genetic subtypes in the Brazilian population and to develop a strategy for molecular diagnosis applicable to routine clinical use. We screened 255 patients from Hospital de Clínicas, Universidade Federal do Paraná for 11 common FA gene mutations. Further analysis by multiplex ligation-dependent probe amplification (MLPA) for FANCA and Sanger sequencing of all coding exons of FANCA , -C , and - G was performed in cases who harbored a single gene mutation. We identified biallelic mutations in 128/255 patients (50.2%): 89, 11, and 28 carried FANCA , FANCC , and FANCG mutations, respectively. Of these, 71 harbored homozygous mutations, whereas 57 had compound heterozygous mutations. In 4/57 heterozygous patients, both mutations were identified by the initial screening, in 51/57 additional analyses was required for classification, and in 2/57 the second mutation remained unidentified. We found 52 different mutations of which 22 were novel. The proposed method allowed genetic subtyping of 126/255 (49.4%) patients at a significantly reduced time and cost, which makes molecular diagnosis of FA Brazilian patients feasible.

We present a systematic review of historical, political, and epidemiologic aspects of AIDS in Brazilian children. Over 25 years, Brazil has developed different strategies to control AIDS in children. Three revisions of criteria for defining AIDS cases in children and nine national guidelines on antiretroviral therapy administration for management of HIV infection were published. These guidelines represent important progress, including aspects of HIV/AIDS surveillance, antiretroviral treatment, opportunistic conditions, prophylaxis, and laboratory testing. Brazil has significantly expanded access to free therapy with different classes of antiretroviral drugs. Initially focusing on treatment for HIV and opportunistic conditions, the scope of treatment guidelines gradually expanded to comprehensive health care for children and adolescents. From 1996 to 2008, the number of AIDS cases and deaths in children has been reduced by 67% and 65%, respectively, as a result of different strategies to prevent mother-to-child transmission of HIV and highly active antiretroviral therapy administration to infected children. Improved morbidity, mortality, and survival of Brazilian children with AIDS demonstrate clear benefits of adopting a policy of free and universal access to antiretroviral drugs associated with comprehensive care. However, important issues remain to be resolved, mainly concerning social, operational, and regional inequalities in coverage and quality of care, and epidemiological surveillance in different regions of the country. This broad review shows that the overall situation of pediatric AIDS in Brazil represents an incomplete process of epidemiologic and demographic transition, with the coexistence of old and new clinical and epidemiologic challenges.

Ionizing radiation in Brazil is used in electricity generation, medicine, industry, agriculture and for research and development purposes. All these activities can generate radioactive waste. At this point, in Brazil, the use of nuclear energy and radioisotopes justifies the construction of a national repository for radioactive wastes of low and intermediate-level. According to Federal Law No. 10308, Brazilian National Commission for Nuclear Energy (CNEN) is responsible for designing and constructing the intermediate and final storages for radioactive wastes. Additionally, a restriction on the construction of Angra 3 is that the repository is under construction until its operation start, attaining somemore » requirements of the Brazilian Environmental Regulator (IBAMA). Besides this NPP, in the National Energy Program is previewed the installation of four more plants, by 2030. In November 2008, CNEN launched the Project RBMN (Repository for Low and Intermediate-Level Radioactive Wastes), which aims at the implantation of a National Repository for disposal of low and intermediate-level of radiation wastes. This Project has some aspects that are unique in the Brazilian context, especially referring to the time between its construction and the end of its institutional period. This time is about 360 years, when the area will be released for unrestricted uses. It means that the Repository must be safe and secure for more than three hundred years, which is longer than half of the whole of Brazilian history. This aspect is very new for the Brazilian people, bringing a new dimension to public acceptance. Another point is this will be the first repository in South America, bringing a real challenge for the continent. The current status of the Project is summarized. (authors)« less

OBJECTIVES: The aims of the current study were 1) to evaluate the reliability and validity of the Brazilian version of the 15-item Myasthenia Gravis Quality of Life Scale and 2) to investigate the quality of life of Brazilian patients with myasthenia gravis and its determinants. METHODS: This cross-sectional study included 69 patients with myasthenia gravis who underwent neurological evaluation and completed questionnaires regarding quality of life (the 36-item Short Form of the Medical Outcomes Study and the 15-item Myasthenia Gravis Quality of Life Scale), anxiety and depressive symptoms. RESULTS: The Brazilian version of the 15-item Myasthenia Gravis Quality of Life Scale showed high internal consistency and good concurrent validity with the 36-item Short Form of the Medical Outcomes Study and its subscales. Determinants of quality of life in Brazilian patients with myasthenia gravis included the current status of myasthenia gravis as assessed by the Myasthenia Gravis Composite, the current prednisone dose and the levels of anxiety and depression. CONCLUSION: The Brazilian version of the 15-item Myasthenia Gravis Quality of Life Scale is a valid instrument. Symptom severity, prednisone dosage and anxiety and depression levels impact the quality of life of patients with myasthenia gravis. PMID:27464292

Animal production is a leading economic activity in Brazil and antibiotics are widely used. However, the occurrence, behavior, and impacts of antibiotics in Brazilian soils are still poorly known. We evaluated the sorption behavior of four fluoroquinolones (norfloxacin, ciprofloxacin, danofloxacin, and enrofloxacin) and five sulfonamides (sulfadiazine, sulfachloropyridazine, sulfamethoxazole, sulfadimidine, and sulfathiazole) in 13 Brazilian soils with contrasting physical, chemical, and mineralogical properties. Fluoroquinolone sorption was very high (Kd≥544 L kg(-1)) whereas sulfonamide sorption ranged from low to high (Kd=0.7-70.1 L kg(-1)), consistent with previous reports in the literature. Soil texture and cation exchange capacity were the soil attributes that most affected sorption. Cation exchange was the most important sorption mechanism for the fluoroquinolones in highly weathered tropical soils, although cation bridging and ion pairing could not be ruled out. Hydrophobic partition played an important role in the sorption of the sulfonamides, but sorption was also affected by non-hydrophobic interactions with organic and/or mineral surfaces. Sorption for both compound classes tended to be higher in soils with high Al and Fe oxihydroxide contents, but they were not correlated with Kd values. No direct effect of soil pH was seen. The fluoroquinolones are not expected to leach even in worst-case scenarios (soils rich in sand and poor in organic carbon), whereas soil attributes dictate leaching potential for the sulfonamides.

2012-03-01

The Alberta Infant Motor Scale (AIMS) is a well-known motor assessment tool used to identify potential delays in infants' motor development. Although Brazilian researchers and practitioners have used the AIMS in laboratories and clinical settings, its translation to Portuguese and validation for the Brazilian population is yet to be investigated. This study aimed to translate and validate all AIMS items with respect to internal consistency and content, criterion, and construct validity. A cross-sectional and longitudinal design was used. A cross-cultural translation was used to generate a Brazilian-Portuguese version of the AIMS. In addition, a validation process was conducted involving 22 professionals and 766 Brazilian infants (aged 0-18 months). The results demonstrated language clarity and internal consistency for the motor criteria (motor development score, α=.90; prone, α=.85; supine, α=.92; sitting, α=.84; and standing, α=.86). The analysis also revealed high discriminative power to identify typical and atypical development (motor development score, P<.001; percentile, P=.04; classification criterion, χ(2)=6.03; P=.05). Temporal stability (P=.07) (rho=.85, P<.001) was observed, and predictive power (P<.001) was limited to the group of infants aged from 3 months to 9 months. Limited predictive validity was observed, which may have been due to the restricted time that the groups were followed longitudinally. In sum, the translated version of AIMS presented adequate validity and reliability.

The cyanobacterial community from Brazilian mangrove ecosystems was examined using a culture-dependent method. Fifty cyanobacterial strains were isolated from soil, water and periphytic samples collected from Cardoso Island and Bertioga mangroves using specific cyanobacterial culture media. Unicellular, homocytous and heterocytous morphotypes were recovered, representing five orders, seven families and eight genera (Synechococcus, Cyanobium, Cyanobacterium, Chlorogloea, Leptolyngbya, Phormidium, Nostoc and Microchaete). All of these novel mangrove strains had their 16S rRNA gene sequenced and BLAST analysis revealed sequence identities ranging from 92.5 to 99.7% when they were compared with other strains available in GenBank. The results showed a high variability of the 16S rRNA gene sequences among the genotypes that was not associated with the morphologies observed. Phylogenetic analyses showed several branches formed exclusively by some of these novel 16S rRNA gene sequences. BLAST and phylogeny analyses allowed for the identification of Nodosilinea and Oxynema strains, genera already known to exhibit poor morphological diacritic traits. In addition, several Nostoc and Leptolyngbya morphotypes of the mangrove strains may represent new generic entities, as they were distantly affiliated with true genera clades. The presence of non-ribosomal peptide synthetase, polyketide synthase, microcystin and saxitoxin genes were detected in 20.5%, 100%, 37.5% and 33.3%, respectively, of the 44 tested isolates. A total of 134 organic extracts obtained from 44 strains were tested against microorganisms, and 26% of the extracts showed some antimicrobial activity.

10 years of 1:1 taping in Belgium - A selection of murder cases involving fibre examination.

PubMed

De Wael, K; Lepot, L; Lunstroot, K; Gason, F

2016-01-01

Since 2002, the 1:1 tape lifting technique on murder victims has been introduced in Belgium. Thirty-six murder cases for which a fibre examination was carried out in our laboratory between 2002 and 2012 are reviewed. These cases all involved the collection of microtraces on 39 victims using a 1:1 taping or similar technique, called semi 1:1 taping. The degree of "positive outcomes" for investigative and comparative fibre cases is high. Especially in cases where the modus operandi of suspects had to be verified, the examination of the 1:1 tape lifting led to very useful fibre results. The findings from some of these fibre cases are used to illustrate the advantages, drawbacks and points of interest of the two collection techniques. These are also compared with the zonal taping technique, another microtrace collection technique applied on victims at the crime scene. Copyright © 2015 The Chartered Society of Forensic Sciences.

Cross-cultural translation and psychometric testing. To translate and cross-culturally adapt the Quebec Back Pain Disability Scale (QDS) to Brazilian Portuguese and to examine its validity and reliability. Current literature shows the need to adopt reliable and internationally standardized methods for the analysis of low back pain. To our knowledge, this specific questionnaire has not been translated and validated for Portuguese-speaking patients. The translation and cross-cultural adaptation of the QDS were developed in agreement with internationally recommended methodology, and the resulting product was evaluated in this study with 54 consecutive patients. Internal consistency was obtained through Cronbach's alpha; reliability was estimated through the intraclass correlation coefficient and the Bland and Altman agreement (d = mean difference). Validity was determined by correlating the scores of the Brazil-QDS with the Brazilian version of the Roland-Morris Questionnaire and Visual Analogue Pain Scale by means of the Spearman rank correlation coefficient. The internal consistency obtained was excellent (Cronbach's alpha = 0.97). Intraobserver and interobserver reliability were considered strong (ICC = 0.93-d = 0.68 and 0.96-d = 0.57, respectively). The correlation with Brazilian Roland-Morris Questionnaire and with the Visual Analogue Scale was high (r = 0.857; r = 0.758, respectively). The data showed that the process of translation and cross-cultural adaptation were successful and that the adapted instrument demonstrated excellent psychometric properties.

To determine consistency of assessment in a new paper case-based structured oral examination in a multi-community pediatrics clerkship, and to identify correctable problems in the administration of examination and assessment process. Nine paper case-based oral examinations were audio-taped. From audio-tapes five community coordinators scored examiner behaviors and graded student performance. Correlations among examiner behaviors scores were examined. Graphs identified grading patterns of evaluators. The effect of exam-giving on evaluators was assessed by t-test. Reliability of grades was calculated and the effect of reducing assessment problems was modeled. Exam-givers differed most in their "teaching-guiding" behavior, and this negatively correlated with student grades. Exam reliability was lowered mainly by evaluator differences in leniency and grading pattern; less important was absence of standardization in cases. While grade reliability was low in early use of the paper case-based oral examination, modeling of plausible effects of training and monitoring for greater uniformity in administration of the examination and assigning scores suggests that more adequate reliabilities can be attained.

To effectively implement the Paris Agreement, capacity in carbon accounting must be strengthened in the developing world, and partnerships with local academic institutions can do the accounting for governments and fill the capacity gap. This paper highlights the Brazilian case, focusing on ways in which climate change science information and transparency are being incorporated in national C accounting initiatives, particularly the national inventory of greenhouse gas (GHG) emissions and removals. We report how the third inventory for the sector of land use, land-use change and forestry (LULUCF) was implemented to address scientific challenges involved in the monitoring of carbon stocks and land-use changes of diverse and complex biomes while addressing international and national policy demands (report and decision support) and transparency to various stakeholders. GHG emissions and removals associated with 2002–2010 carbon changes in aboveground, belowground biomass, necromass and soil carbon by land use and land cover changes were estimated for all Brazilian biomes, and for the Amazon estimates were also presented for the periods of 2002–2005 and 2005–2010. The inventory improved regional estimates for carbon stock and national emission factors with the support and engagement of the scientific community. Incorporation of local context is essential to reduce uncertainties and properly monitor efforts to contribute to GHG emission/reduction targets. To promote transparency and make information more accessible, the national inventory results were made available by the National Emissions Registry System (SIRENE). This system was built to support climate change policies as an important legal apparatus and by increasing access to emissions and land-use change data.

Sexuality education has been valued since the 1960s in medical schools worldwide. Although recent studies reaffirm the importance of incorporating sexuality into medical education, there are data gaps concerning how this happens in Brazil. To understand how Brazilian medical school professors teach sexuality in undergraduate courses. An exploratory, cross-sectional descriptive study was conducted. A total of 207 professors from 110 Brazilian medical schools responded to an online semistructured questionnaire about the characteristics of the sexuality-related topics offered. The main variables assessed were contact hours devoted to sexuality, disciplines in which sexuality topics were taught, sexuality-related course titles, and sexuality-related topics addressed. Questionnaires were tabulated and analyzed using descriptive statistics for frequency distribution. The response rate to the questionnaire was 77.2%. Almost all professors (96.3%) addressed sexuality-related topics mainly in the third and fourth years as clinical disciplines, with a 6-hour load per discipline. Gynecology was the discipline in which sexuality-related topics were most often taught (51.5%), followed by urology (18%) and psychiatry (15%). Sexuality-related topics were addressed mainly in classes on sexually transmitted diseases and AIDS (62.4%) and on the anatomy and physiology of the reproductive system (55.4%). About 25% of the professors reported teaching courses with a sexuality-related title. There was emphasis on the impact of diseases and sexual habits (87.9%) and sexual dysfunction (75.9%). Less than 50% of professors addressed nonnormative sexuality or social aspects of sexuality. The teaching of sexuality in Brazilian medical schools occurred in a nonstandardized and fragmented fashion across several disciplines. The topic was incorporated with an organic and pathological bias, with a weak emphasis on the social aspects of sexuality and the variety of human sexual behaviors. The

Malaria represents one of the most important infectious disease threats to deployed military forces; most personnel from developed countries are nonimmune personnel and are at high risk of infection and clinical malaria. This is especially true for forces deployed to highly-endemic areas in Africa and Southeast Asia where drug-resistant malaria is common. We conducted an outbreak investigation of malaria cases in Angola where a total of 439 nonimmune Brazilian troops were deployed for a 6-month period in 1995-1996. A post-travel medical evaluation was also performed on 338 (77%) of the 439 soldiers upon return to Brazil. Questionnaire, medical record, thick/thin smear, and serum anti-Plasmodium falciparum antibody titer (by IFA) data were obtained. Peak serum mefloquine (M) and methylmefloquine (MM) metabolite levels were measured in a subsample of 66 soldiers (42 cases, 24 nonmalaria controls) who were taking weekly mefloquine prophylaxis (250 mg). Seventy-eight cases of malaria occurred among the 439 personnel initially interviewed in Angola (attack rate = 18%). Four soldiers were hospitalized, and 3 subsequently died of cerebral malaria. Upon return to Brazil, 63 (19%) of 338 soldiers evaluated were documented to have had clinical symptoms and a diagnosis of malaria while in Angola. In addition, 37 (11%) asymptomatically infected individuals were detected upon return (< 1% parasitemia). Elevated, post-travel anti-P. falciparum IFA titers (> or = 1:64) were seen in 101 (35%) of 292 soldiers tested, and was associated with a prior history of malaria in-country (OR = 3.67, 95% CI 1.98-6.82, p <.001). Noncompliance with weekly mefloquine prophylaxis (250 mg) was associated with a malaria diagnosis in Angola (OR = 3.75, 95% CI 0.97-17.41, p =.03) but not with recent P. falciparum infection (by IFA titer). Mean peak levels (and ratios) of serum M and MM were also found to be lower in those who gave a history of malaria while in Angola. Malaria was a significant cause

An empirical study of the Brazilian option market is presented in light of three option pricing models, namely the Black-Scholes model, the exponential model, and a model based on a power law distribution, the so-called q-Gaussian distribution or Tsallis distribution. It is found that the q-Gaussian model performs better than the Black-Scholes model in about one third of the option chains analyzed. But among these cases, the exponential model performs better than the q-Gaussian model in 75% of the time. The superiority of the exponential model over the q-Gaussian model is particularly impressive for options close to the expiration date, where its success rate rises above ninety percent.

Propolis contains a variety of bioactive components and possesses many biological properties. This study was designed to evaluate potential effects of Brazilian green propolis on glucose metabolism and antioxidant function in patients with type 2 diabetes mellitus (T2DM). In the 18-week randomized controlled study, enrolled patients with T2DM were randomly assigned to Brazilian green propolis group (900 mg/day) (n = 32) and control group (n = 33). At the end of the study, no significant difference was found in serum glucose, glycosylated hemoglobin, insulin, aldose reductase or adiponectin between the two groups. However, serum GSH and total polyphenols were significantly increased, and serum carbonyls and lactate dehydrogenase activity were significantly reduced in the Brazilian green propolis group. Serum TNF-α was significantly decreased, whereas serum IL-1β and IL-6 were significantly increased in the Brazilian green propolis group. It is concluded that Brazilian green propolis is effective in improving antioxidant function in T2DM patients.

The pathogenesis of Guillain-Barré Syndrome (GBS) is not entirely understood, but includes infection-induced aberrant immune responses. Genetic polymorphisms in Fc gamma receptor genes (FCGR) have been associated with GBS. We assessed whether polymorphisms rs1801274 in FCGR2A and rs396991 in FCGR3A were associated with GBS in a Brazilian population. We genotyped 141 GBS cases and 364 healthy controls from Brazil for both polymorphisms. The FCGR genotypes and alleles frequencies did not differ significantly between GBS and controls. In addition, there was no genetic association with either severity or clinical outcomes. We conclude that these FCGR polymorphisms are not associated with susceptibility to Guillain-Barré Syndrome in this Brazilian population. Copyright © 2016. Published by Elsevier B.V.

To estimate the prevalence and severity of dental caries in Brazilian children and the association with individual and contextual factors. Data were taken from the Brazilian Oral Health Survey (SBBrasil 2010) a sample of 7,247 12-year-olds. The data were collected using clinical examinations and interviews. The dependent variables were the prevalence of dental caries (decayed, missing and filled teeth [DMFT] ≥ 1 and DMFT ≥ 4). Bivariate (Rao Scott test) and multivariate (Poisson regression) analyses were carried out. The individual variables were sociodemographic variables, periodontal health and reporting discomfort while brushing. Contextual factors were the presence of water fluoridation, the percentage of residences connected to the water supply and median income of the municipality. The prevalence of DMFT ≥ 1 was 56.0%. Mean DMFT was 2.04 (95%CI 1.76;2.31) and 22.2% of children had DMFT ≥ 4. Caries experience was significantly more common in children with black, brown or yellow skin; in low-income families; in children with dental calculus or bleeding gums and in those who reported discomfort while brushing. Living in towns with fluoridated tap water, with low coverage of water supply and with low median income were contextual factors associated with the disease. The prevalence of dental caries in Brazilian 12-year-olds was low, according to World Health Organization criteria. There were significant geographical and socioeconomic inequalities in levels of the disease.

The aim of this review is to underline the reasons why a post-mortem examination has to be performed in all cases of juvenile sudden death. Sudden death in children and young adults can be caused by potentially heritable cardiovascular disorders and fatal outcome is often the first symptom in apparently healthy subjects. In these cases, a careful autopsy, performed according to a standardized protocol, becomes the sole diagnostic tool to guide clinical and molecular genetic family screening and to adopt the proper therapeutic and preventive strategies. Thus, a post-mortem examination is a fundamental part of a multidisciplinary approach to the issue of juvenile sudden death.

The proximity of the Paralympic Games Rio 2016 opens the discussion about the possibility of building a career in Paralympic sport. This study aims to present the characteristics and challenges present in the sporting career of the Brazilian Paralympic athlete. The study was structured under three main guiding topics: the different moments of Paralympic Sport, the career characteristics of paralympians and the consequences of sports results for their careers. Currently, Paralympic sports has its focus on high performance, as the constant necessity for good results is an ever present reality. The characteristics and challenges of sporting careers reveal the current situation for Brazilian Paralympic sports in all of its stages (pre-transition, transition and post-transition). Upon reflecting on the career of the Brazilian paralympic athlete a debate opens up concerning future perspectives and particularly on an understanding of the existing challenges for consolidation. Structural problems such as venues for training, lack of awareness on the part of the private sector and the non-renewal of human resources, seem to be the main obstacles for the consolidation of paralympic careers in Brazil.

Abstract The first horses were brought to Brazil by the colonizers after 1534. Over the centuries, these animals evolved and adapted to local environmental conditions usually unsuitable for exotic breeds, thereby originating locally adapted Brazilian breeds. The present work represents the first description of maternal genetic diversity in these horse breeds based on D-loop sequences. A D-Loop HSV-I fragment of 252 bp, from 141 horses belonging to ten Brazilian breeds / genetic groups (locally adapted and specialized breeds) were analysed. Thirty-five different haplotypes belonging to 18 haplogroups were identified with 33 polymorphic sites. Haplotype diversity (varying from 0.20 to 0.96) and nucleotide diversity (varying from 0.0039 to 0.0239) was lower for locally adapted than for specialized breeds, with the same pattern observed for FST values. Haplogroups identified in Brazilian breeds are in agreement with previous findings in South American samples. The low variability observed mainly in locally adapted breeds, indicates that, to ensure conservation of these breeds, careful reproductive management is needed. Additional genetic characterization studies are required to support accurate decision-making. PMID:28863209

A descriptive survey was performed in order to assess the statistical content and quality of Brazilian and international dental journals, and compare their evolution throughout the last decades. The authors identified the reporting and accuracy of statistical techniques in 1000 papers published from 1970 to 2000 in seven dental journals: three Brazilian (Brazilian Dental Journal, Revista de Odontologia da Universidade de Sao Paulo and Revista de Odontologia da UNESP) and four international journals (Journal of the American Dental Association, Journal of Dental Research, Caries Research and Journal of Periodontology). Papers were divided into two time periods: from 1970 to 1989, and from 1990 to 2000. A slight increase in the number of articles that presented some form of statistical technique was noticed for Brazilian journals (from 61.0 to 66.7%), whereas for international journals, a significant increase was observed (65.8 to 92.6%). In addition, a decrease in the number of statistical errors was verified. The most commonly used statistical tests as well as the most frequent errors found in dental journals were assessed. Hopefully, this investigation will encourage dental educators to better plan the teaching of biostatistics, and to improve the statistical quality of submitted manuscripts.

ABSTRACT OBJECTIVE To describe food and macronutrient intake profile and estimate the prevalence of inadequate micronutrient intake of Brazilian adolescents. METHODS Data from 71,791 adolescents aged from 12 to 17 years were evaluated in the 2013-2014 Brazilian Study of Cardiovascular Risks in Adolescents (ERICA). Food intake was estimated using 24-hour dietary recall (24-HDR). A second 24-HDR was collected in a subsample of the adolescents to estimate within-person variability and calculate the usual individual intake. The prevalence of food/food group intake reported by the adolescents was also estimated. For sodium, the prevalence of inadequate intake was estimated based on the Tolerable Upper Intake Level (UL). The Estimated Average Requirement (EAR) method used as cutoff was applied to estimate the prevalence of inadequate nutrient intake. All the analyses were stratified according to sex, age group and Brazilian macro-regions. All statistical analyses accounted for the sample weight and the complex sampling design. RESULTS Rice, beans and other legume, juice and fruit drinks, breads and meat were the most consumed foods among the adolescents. The average energy intake ranged from 2,036 kcal (girls aged from 12 to 13 years) to 2,582 kcal (boy aged from14 to 17 years). Saturated fat and free sugar intake were above the maximum limit recommended (< 10.0%). Vitamins A and E, and calcium were the micronutrients with the highest prevalence of inadequate intake (> 50.0%). Sodium intake was above the UL for more than 80.0% of the adolescents. CONCLUSIONS The diets of Brazilian adolescents were characterized by the intake of traditional Brazilian food, such as rice and beans, as well as by high intake of sugar through sweetened beverages and processed foods. This food pattern was associated with an excessive intake of sodium, saturated fatty acids and free sugar. PMID:26910551

Brazilian Soil Science Society: brief history, achievements and challenges for the near future

The Brazilian Soil Science Society (SBCS) is one of the oldest scientific societies in Brazil. It was created in October 1947 during the 1st Brazilian Meeting of Soil Science held at the headquarters of the Agricultural Chemistry Institute of Rio de Janeiro, at present the Soils Institute of the Brazilian Agricultural Research Centre. Its origin lies within the Interamerican Conference of Agriculture, Caracas, 1945, the 2nd Pan American Congress of Mining and Geology, Petropolis, Rio de Janeiro, 1946 and the 5th Brazilian Congress of Chemistry, Porto Alegre, 1947. Its first president was Álvaro Barcelos Fagundes, who was the only Brazilian participant at the 1st International Congress of Soil Science and Transcontinental Excursion held in United States of America, in 1927. At that time he was engaged in research work at the New Jersey Agricultural Experiment Station, at the Rutgers University where he did a doctorate under the guidance of Professor Selman Waksman. The society started with 47 members and presently has nearly 900 members. In its first phase the Brazilian Soil Science Society was housed at the Agricultural Chemistry Institute in Rio de Janeiro and its main activity was the biannual Brazilian Congress of Soil Science. In 1975 its headquarters moved to the Agronomic Institute of Campinas with the creation of its executive board and the start of publication of the Brazilian Journal of Soil Science (1977) as well as the society bulletin (1976). In 1997 its executive office moved to the Soils Department at the Federal University of Viçosa. Nowadays it has a structure similar to the one from the IUSS: the society is organized in four divisions (Soil in space and time, Soils properties and processes, Soil use and management and Soil, environment and society) which encompass 14 technical commissions and eight State or Regional nuclei. The Brazilian Congresses of Soil Science happen without interruption since 1947. The first one had had 72 participants that

Seasonal distribution of blood donation hinders efforts to provide a safe and adequate blood supply leading to chronic and persistent shortages. This study examined whether holidays, geographical area and donation type (community versus replacement) has any impact on the fluctuation of donations. The numbers of blood donations from 2007 through 2010 in three Brazilian Retrovirus Epidemiological Donor Study II (REDS-II) participating centers were analyzed according to the week of donation. The weeks were classified as holiday or non-holiday. To compare donations performed during holiday versus non-holiday weeks, tabulations and descriptive statistics for weekly donations by blood center were examined and time series analysis was conducted. The average weekly number of donations varied according to the blood center and type of week. The average number of donations decreased significantly during Carnival and Christmas and increased during the Brazilian National Donor Week. The fluctuation was more pronounced in Recife and Belo Horizonte when compared to São Paulo and higher among community donors. National bank holidays affect the blood supply by reducing available blood donations. Blood banks should take into account these oscillations in order to plan local campaigns, aiming at maintaining the blood supply at acceptable levels.

Expanding worldwide urban solid waste recycling: The Brazilian social technology in waste pickers inclusion.

'If an integrated urban waste management system includes the informal recycling sector (IRS), there is a good chance that more solid waste is recycled' is common sense. However, informal integration brings additional social, environmental, and economic benefits, such as reduction of operational costs and environmental impacts of landfilling. Brazil is a global best practice example in terms of waste picker inclusion, and has received international recognition for its recycling levels. In addition to analysing the results of inclusive recycling approaches, this article evaluates a selection of the best Brazilian inclusive recycling practices and summaries and presents the resulting knowledge. The objective is to identify processes that enable the replication of the inclusion of the informal recycling sector model as part of municipal solid waste management. Qualitative and quantitative data have been collected in 25 Brazilian cities that have contracted waste pickers co-operatives for door-to-door selective collection of recyclables. Field data was collected in action research projects that worked with waste pickers co-operatives between 2006 and 2013. The Brazilian informal recycling sector integration model improves municipal solid waste recycling indicators: it shows an increase in the net tonness recycled, from 140 to 208 t month(-1), at a much lower cost per tonne than conventional selective collection systems. Inclusive systems show costs of US$35 per tonne of recyclables collected, well below the national average of US$195.26. This inclusive model improves the quality of collected material and the efficiency of municipal selective collection. It also diminishes the negative impacts of informal recycling, by reducing child labour, and by improving the conditions of work, occupational health and safety, and uncontrolled pollution. Although treating the Brazilian experience as a blueprint for transfer of experience in every case is unrealistic, the results

Genomic Ancestry, Self-Reported “Color” and Quantitative Measures of Skin Pigmentation in Brazilian Admixed Siblings

A current concern in genetic epidemiology studies in admixed populations is that population stratification can lead to spurious results. The Brazilian census classifies individuals according to self-reported “color”, but several studies have demonstrated that stratifying according to “color” is not a useful strategy to control for population structure, due to the dissociation between self-reported “color” and genomic ancestry. We report the results of a study in a group of Brazilian siblings in which we measured skin pigmentation using a reflectometer, and estimated genomic ancestry using 21 Ancestry Informative Markers (AIMs). Self-reported “color”, according to the Brazilian census, was also available for each participant. This made it possible to evaluate the relationship between self-reported “color” and skin pigmentation, self-reported “color” and genomic ancestry, and skin pigmentation and genomic ancestry. We observed that, although there were significant differences between the three “color” groups in genomic ancestry and skin pigmentation, there was considerable dispersion within each group and substantial overlap between groups. We also saw that there was no good agreement between the “color” categories reported by each member of the sibling pair: 30 out of 86 sibling pairs reported different “color”, and in some cases, the sibling reporting the darker “color” category had lighter skin pigmentation. Socioeconomic status was significantly associated with self-reported “color” and genomic ancestry in this sample. This and other studies show that subjective classifications based on self-reported “color”, such as the one that is used in the Brazilian census, are inadequate to describe the population structure present in recently admixed populations. Finally, we observed that one of the AIMs included in the panel (rs1426654), which is located in the known pigmentation gene SLC24A5, was strongly associated with

The concept of "scientific culture" varies historically, and the examination of its continuities and transformations can help us understand the relationship between the scientific community and society. The views on the role of science in society go far beyond the advancement of a particular form of knowledge and its possible or promising fruit. They involve values, postures and practices to be disseminated and reveal expectations of social and cultural advancement. This article discusses four expressive visions of different moments in Brazilian history. The formulations of four influential authors in scientific and educational policies of the country at different times are presented and analyzed: Miguel Ozorio de Almeida, Anísio Teixeira, Maurício Rocha e Silva and Carlos Vogt.

Biotypology, regionalism, and the construction of a plural Brazilian bodily identity, 1930s.

2016-12-01

This article investigates regional biotypological studies and the construction of biological deterministic discourses about the Brazilian identity in the 1930s. Biotypological research was undertaken to determine the normal body type of the Brazilian man, using its peculiar classificatory lexicon. Studies into the bodily profile of specific regions, like the northeast and São Paulo state, featured in this research. In the context of the contemporary debates about race, miscegenation, and national identity, these investigations were geared towards biological determinism and the influence of the environment and social and cultural aspects on the bodily development of Brazilians. It is shown how regional biotypological studies echoed racial, normalizing, exclusive viewpoints and contributed to the construction of a miscegenated Brazilian bodily identity.

GNSS positioning can be carried out in relative or absolute approach. In the last years, more attention has been driven to the real time precise point positioning (PPP). To achieve centimeter accuracy with this method in real time it is necessary to have available the satellites precise coordinates as well as satellites clocks corrections. The coordinates can be used from the predicted IGU ephemeris, but the satellites clocks must be estimated in a real time. It can be made from a GNSS network as can be seen from EUREF Permanent Network. The infra-structure to realize the PPP in real time is being available in Brazil through the Brazilian Continuous Monitoring Network (RBMC) together with the Sao Paulo State GNSS network which are transmitting GNSS data using NTRIP (Networked Transport of RTCM via Internet Protocol) caster. Based on this information it was proposed a PhD thesis in the Univ. Estadual Paulista (UNESP) aiming to investigate and develop the methodology to estimate the satellites clocks and realize PPP in real time. Then, software is being developed to process GNSS data in the real time PPP mode. A preliminary version of the software was called PPP_RT and is able to process GNSS code and phase data using precise ephemeris and satellites clocks. The PPP processing can be accomplished considering the absolute satellite antenna Phase Center Variation (PCV), Ocean Tide Loading (OTL), Earth Body Tide, among others. The first order ionospheric effects can be eliminated or minimized by ion-free combination or parameterized in the receiver-satellite direction using a stochastic process, e.g. random walk or white noise. In the case of ionosphere estimation, a pseudo-observable is introduced in the mathematical model for each satellite and the initial value can be computed from Klobuchar model or from Global Ionospheric Map (GIM). The adjustment is realized in the recursive mode and the DIA (Detection Identification and Adaptation) is used for quality control. In

Climate change is expected to have a significant impact on fire occurrence and activity, particularly in Brazil, a region known to be fire-prone [1]. The Brazilian savanna, commonly referred to as cerrado, is a fire-adapted biome covering more than 20% of the country's total area. It presents the highest numbers of fire events, making it particularly susceptible to changes in climate. It is thus essential to understand the present fire regimes in Brazilian biomes, in order to better evaluate future patterns. The CPTEC/INPE, the Brazilian Center for Weather Forecasting and Climate Research at the Brazilian National Institute of Space Research developed a fire danger index based on the occurrence of hundreds of thousands of fire events in the main Brazilian biomes [2]: the Meteorological Fire Danger Index (MFDI). This index indicates the predisposition of vegetation to be burned on a given day, for given climate conditions preceding that day. It relies on daily values of air temperature, relative humidity, accumulated precipitation and vegetation cover. In this study we aim to access the capability of the MFDI to accurately replicate present fire conditions for different biomes, with a special focus on cerrado. To this end, we assess the link between the MFDI as calculated by three different reanalysis (ERA-Interim, NCEP/DOE Reanalysis 2 and MERRA-2) and the observed burned area. We further calculate the validated MFDI using a regional climate model, the RCA4 as forced by EC-Earth from CORDEX, to understand the ability of the model to characterize present fire danger. Finally, the need to calibrate the model to better characterize future fire danger was also evaluated. This work was developed within the framework of the Brazilian Fire-Land-Atmosphere System (BrFLAS) Project financed by the Portuguese and Brazilian science foundations, FCT and FAPESP (project references FAPESP/1389/2014 and 2014/20042-2).

Adiponectin circulates in different multimer complexes comprised of low molecular weight trimeric form (LMW), hexamer of middle molecular weight (MMW) and high molecular weight multimers (HMW). In Japanese-Brazilians, a population with high prevalence of glucose metabolism disturbances, we examined the associations of total adiponectin and its multimers with diabetes mellitus. Two study groups were examined: 26 patients with diabetes mellitus (DM,14 women and 12 men, aged 55.3 ± 8.6 years) and 27 age-matched control subjects with normal glucose tolerance (NGT,12 women and 15 men, aged 54.0 ± 9.2 years). We found no significant differences in total [NGT: 6.90 ug/ml (4.38-13.43); DM: 5.38 ug/ml (3.76-8.56), p = 0.35], MMW [NGT:2.34 ug/ml (1.38-3.25); DM: 1.80 ug/ml (1.18-2.84), p = 0.48] or LMW adiponectin [NGT: 2.07 ug/ml (1.45-3.48), DM: 2.93 ug/ml (1.78-3.99), p = 0.32] between groups. In contrast, HMW adiponectin levels were significantly lower in patients with DM [TGN: 2.39 ug/ml (1.20-4.75); DM: 1.04 ug/ml (0.42-1.60), p = 0.001]. A logistic regression analysis was done to identify independent associations with diabetes mellitus. The results showed that HOMA-IR and HMW adiponectin in women were independently associated with diabetes mellitus. The current investigation demonstrates that in Japanese-Brazilians HMW adiponectin is selectively reduced in individuals with type 2 diabetes, while no differences were found in MMW and LMW adiponectin isoforms.

Research suggests that alcoholic beverage advertisements may have an adverse effect on teenagers and young adults, owing to their vulnerability to suggestive message content. This study was designed to evaluate perceived violations of the content guidelines of the Brazilian alcohol marketing self-regulation code, based on ratings of the five most popular beer advertisements broadcast on television in the summer of 2005-2006 and during the 2006 FIFA (Federation Internationale de Football Association) World Cup games. Five beer advertisements were selected from a previous study showing that they were perceived to be highly appealing to a sample of Brazilian teenagers. These advertisements were evaluated by a sample of Brazilian high school students using a rating procedure designed to measure the content of alcohol advertisements covered in industry self-regulation codes. All five advertisements were found to violate multiple guidelines of the Brazilian code of marketing self-regulation. The advertisement with the greatest number of violations was Antarctica's "Male Repellent," which was perceived to violate 11 of the 16 guidelines in the code. Two advertisements had nine violations, and one had eight. The guidelines most likely to be violated by these advertisements were Guideline 1, which is aimed at protecting children and teenagers, and Guideline 2, which prohibits content encouraging excessive and irresponsible alcoholic beverage consumption. The five beer advertisements rated as most appealing to Brazilian teenagers were perceived by a sample of the same population to have violated numerous principles of the Brazilian self-regulation code governing the marketing of alcoholic beverages. Because of these numerous perceived code violations, it now seems important for regulatory authorities to submit industry marketing content to more systematic evaluation by young people and public health experts and for researchers to focus more on the ways in which alcohol

This article presents an analysis of Brazilian research on High Energy Physics (HEP) indexed by Web of Science (WoS) from 1983 to 2013. Scientometric indicators for output, collaboration and impact were used to characterize the field under study. The results show that the Brazilian articles account for 3% of total HEP research worldwide and that the sharp rise in the scientific activity between 2009 and 2013 may have resulted from the consolidation of graduate programs, the increase of the funding and of the international collaboration as well as the implementation of the Rede Nacional de Física de Altas Energias (RENAFAE) in 2008. Our results also indicate that the collaboration patterns in terms of the authors, the institutions and the countries confirm the presence of Brazil in multinational Big Science experiments, which may also explain the prevalence of foreign citing documents (all types), emphasizing the international prestige and visibility of the output of Brazilian scientists. We concluded that the scientometric indicators suggested scientific maturity in the Brazilian HEP community due to its long history of experimental research.

Summary: In 1984, children presented to the emergency department of a hospital in the small town of Promissão, São Paulo State, Brazil, with an acute febrile illness that rapidly progressed to death. Local clinicians and public health officials recognized that these children had an unusual illness, which led to outbreak investigations conducted by Brazilian health officials in collaboration with the U.S. Centers for Disease Control and Prevention. The studies that followed are an excellent example of the coordinated and parallel studies that are used to investigate outbreaks of a new disease, which became known as Brazilian purpuric fever (BPF). In the first outbreak investigation, a case-control study confirmed an association between BPF and antecedent conjunctivitis but the etiology of the disease could not be determined. In a subsequent outbreak, children with BPF were found to have bacteremia caused by Haemophilus influenzae biogroup aegyptius (H. aegyptius), an organism previously known mainly to cause self-limited purulent conjunctivitis. Molecular characterization of blood and other isolates demonstrated the clonal nature of the H. aegyptius strains that caused BPF, which were genetically distant from the diverse strains that cause only conjunctivitis. This led to an intense effort to identify the factors causing the unusual invasiveness of the BPF clone, which has yet to definitively identify the virulence factor or factors involved. After a series of outbreaks and sporadic cases through 1993, no additional cases of BPF have been reported. PMID:18854482

To determine the association between body composition and frailty in older Brazilian subjects. This is a Cross-sectional study called FIBRA-BR and developed in community Brazilian aged ≥65 (n=5638). Frailty was assessed according to Fried et al. definition and body composition was determined by BMI, waist circumference and waist-hip ratio. The lowest prevalence of frailty was observed in subjects with BMI between 25.0 and 29.9kg/m 2 . Subjects with a BMI <18.5 and those with elevated WC presented a higher risk of frailty compared to eutrophic subjects (odds ratio (OR)=3.10; 95% CI: 2.06-4.67) and (OR=1.15; 95% CI: 1.03-1.27), respectively. Being overweight was protective for pre-frailty (OR=0.48; 95% CI: 0.4-0.58) and frailty (OR=0.77; 95% CI: 0.67-0.9). Obese older people presented a higher risk of pre-frailty only (OR=1.29; 95% CI: 1.09-1.51). Older people with high WC showed a greater proportion of frailty regardless of the BMI range. Undernutrition is associated with pre-frailty and frailty in Brazilian elderly subjects, whereas obesity is associated only with pre-frailty. Overweight seems to have a protective effect against the syndrome. The excess of abdominal fat is associated with both profiles independent of the BMI. Copyright © 2017 Elsevier B.V.

ABSTRACT OBJECTIVE To describe the translation and early stages of cross-cultural adaptation of the questionnaire Verwachtingen over werken (or “Return-to-work self-efficacy”) for workers in sick leave due to mental disorders, from the original in Dutch to the Brazilian Portuguese language. METHODS A panel gathering experts was formed to determine the questionnaire conceptual and item equivalence. For semantic equivalence, the Dutch-Portuguese Brazilian translations were consolidated and consensus meetings were held to structure versions of the instrument. Each version was back-translated from Brazilian Portuguese to Dutch and evaluated by one of the authors of the original version. The final version was submitted to two pre-tests for operational equivalence. RESULTS The original questionnaire in Dutch was translated twice to Brazilian Portuguese. During the process, four consensus meetings of the experts’ panel were performed to create the versions. Each version was back-translated to Dutch. One of the authors of the original questionnaire performed an evaluation on the first three versions until the definition of the final one, which was titled Expectativas sobre o trabalho (Expectations about work). Pre-tests’ participants did not reported problems to fill the questionnaire. CONCLUSIONS Results indicate that the Brazilian Portuguese cross-culturally adapted version maintains the original meaning of the questionnaire, while including characteristics peculiar to the Brazilian reality. Measurement and functional equivalence of this version must still be evaluated before its application can be recommended for workers who have been absent from work due to mental disorders.

To describe the profile of insured individuals that filed claims for sickness benefits and compare the results of the administrative and legal investigations. This case series included 114 insured persons that filed lawsuits against the Brazilian National Institute of Social Security (Instituto Nacional de Seguridade Social, INSS). They underwent psychiatric examinations required by the Brazilian Federal Social Security Special Court in Florianópolis from August to December 2010. Mean age was 47 years, and participant age ranged from 24 to 64 years. Most insured individuals were women (79%), and most were employed (67.5%) and self-employed (26.5%) workers. Mean contribution time was 99.9 months, ranging from 8 to 352 months. Mean benefit duration was 20.4 months, ranging from 2 to 97 months. The most prevalent category of workers was service workers, store and supermarket salespeople (54.4%), followed by administrative workers (19.3%). Only 17 participants were found to be unable to work after benefit cessation, a 14.9% mismatch between administrative and legal investigations. The most frequent diagnoses were mood disorders (59.6%) and anxiety disorders (17.5%).

Growing challenges with respect to preserving the environment have forced changes in company operational structures. Thus, the objective of this article is to measure the evidence of Environmental Management using the Item Response Theory, based on website analysis from Brazilian industrial companies from sectors defined through the scope of the research. This is a qualitative, exploratory, and descriptive study related to an information collection and analysis instrument. The general view of the research problem with respect to the phenomenon under study in based on multi-case studies, with the methodological outline based on the theoretical reference used. Primary data was gathered from 270 company websites from 7 different Brazilian sectors and led to the creation of 26 items approved by environmental specialists. The results were attained with the measuring of Environmental Management evidence via the Item Response Theory, providing a clear order of the items involved based on each item's level of difficulty, quality, and propriety. This permitted the measurement of each item's quality and propriety, as well as that of the respondents, placing them on the same analysis scale. Increasing the number of items and companies involved is suggested fEor future research in order to permit broader sector analysis.

An overview of ecological, epidemiological and clinical findings of potential arthropod-borne encephalitis viruses circulating in the Amazon Region of Brazil are discussed. These viruses are the Eastern Equine Encephalitis (EEE), Western Equine Encephalitis (WEE), St. Louis Encephalitis (SLE), Mucambo (MUC) and Pixuna (PIX). These last two are subtypes (III and IV) of Venezuelan Equine Encephalitis virus. The areas of study were the highways and projects of development, as well as places where outbreaks of human diseases caused by arboviruses had been detected. These viruses are widespread in all Amazonia, and at least four of them, EEE, WEE, SLE and MUC are pathogenic to man. EEE and WEE infections were detected by serology, while SLE and MUC by either serology and virus isolation. The PIX virus has the lowest prevalence and, it was isolated in only a few cases, one being from a laboratory infection. Wild birds are the main hosts for all these viruses, except MUC, whose major hosts are rodents. The symptoms presented by infected people were generally a mild febrile illness. Although, jaundice was observed in two individuals from whom SLE was isolated. A comparison of the clinical symptoms presented by the patients in the Amazon Region and other areas of America, especially in the USA is made. In Brazilian Amazon region epidemics have not been detected although, at least, one EEE epizootic was recorded in Bragança, Para State, in 1960. At that time, of 500 horses that were examined 61% were positive to EEE by HI and of them 8.2% died. On the other hand, SLE has caused four epizootics in a forest near Belem. Wild birds and sentinel monkeys were infected, but no human cases were reported.

Summary Introduction: Currently, the Brazilian government has certificated nearly 140 specialized centers in hearing aid fittings through the Brazilian National Health System (SUS). Remote fitting through the Internet can allow a broader and more efficient coverage with a higher likelihood of success for patients covered by the SUS, as they can receive fittings from their own homes instead of going to the few and distant specialized centers. Aim: To describe a case of remote fitting between 2 cities, with revision of the literature. Method: Computer gears, a universal interface, and hearing aids were used. Case study: An audiologist located in a specialized center introduced a new hearing aid and its fitting procedure to a remote center (200 km away). The specialized center helped the remote center in fitting a hearing aid in 2 patients, and performed fitting in one of its own patients. The whole process was done through the Internet with audio and video in real time. Results: Three patients were fitted remotely. Three audiologists were remotely trained on how to fit the hearing aids. Conclusions: Remote fitting of hearing aids is possible through the Internet, as well as further supplying technical training to a remote center about the fitting procedures. Such a technological approach can help the government advance public policies on hearing rehabilitation, as patients can be motivated about maintaining their use of hearing aids with the option to ask for help in the comfort of their own homes.

Introduction The objective of this study was to identify the patterns of dental variables of adolescent Japanese-Brazilian descents with normal occlusion, and also to compare them with a similar Caucasian and Mongoloid sample. Methods Lateral cephalometric radiographs were used to compare the groups: Caucasian (n = 40), Japanese-Brazilian (n = 32) and Mongoloid (n = 33). The statistical tests used were one-way ANOVA and ANCOVA. The cephalometric measurements used followed the analyses of Steiner, Tweed and McNamara Jr. Results Statistical differences (P < 0.05) indicated a smaller interincisal angle and overbite for the Japanese-Brazilian sample, when compared to the Caucasian sample, although with similar values to the Mongoloid group. Conclusion The dental patterns found for the Japanese-Brazilian descents were, in general, more similar to those of the Mongoloid sample. PMID:25279521

The Convention on Biological Diversity proposed the Aichi Biodiversity Targets to improve conservation policies and to balance economic development, social welfare, and the maintenance of biodiversity/ecosystem services. Brazil is a signatory of the Aichi Biodiversity Targets and is the most diverse country in terms of freshwater fish, but its national policies have supported the development of unsustainable commercial and ornamental aquaculture, which has led to serious disturbances to inland ecosystems and natural resources. We analyzed the development of Brazilian aquaculture to show how current aquaculture expansion conflicts with all 20 Aichi Targets. This case suggests that Brazil and many other megadiverse developing countries will not meet international conservation targets, stressing the need for new strategies, such as the environmental management system, to improve biodiversity conservation.

Wolfram syndrome (WS) is a rare, progressive, neurodegenerative disorder with an autosomal recessive pattern of inheritance. The gene for WS, WFS1, was identified on chromosome 4p16 and most WS patients carry mutations in this gene. However, some studies have provided evidence for genetic heterogeneity and the genotype-phenotype relationships are not clear. Our aim was to ascertain the spectrum of WFS1 mutations in Brazilian patients with WS and to examine the phenotype-genotype relationships in these patients. Clinical characterization and analyses of the WFS1 gene were performed in 27 Brazilian patients with WS from 19 families. We identified 15 different mutations in the WFS1 gene in 26 patients, among which nine are novel. All mutations occurred in exon 8, except for one missense mutation which was located in exon 5. Although we did not find any clear phenotype-genotype relationship in patients with mutations in exon 8, the homozygous missense mutation in exon 5 was associated with a mild phenotype: onset of diabetes mellitus and optic atrophy during adulthood with good metabolic control being achieved with low doses of sulfonylurea. Our data show that WFS1 is the major gene involved in WS in Brazilian patients and most mutations are concentrated in exon 8. Also, our study increases the spectrum of WFS1 mutations. Although no clear phenotype-genotype relationship was found for mutations in exon 8, a mild phenotype was associated with a homozygous missense mutation in exon 5.

In 2005 a serious case of child sexual abuse from the region of Southern Denmark was revealed to the Danish public. The case became known as the 'Tønder-case'. It was the first in a series of 4-5 serious cases of child maltreatment in Denmark, cases which spurred heavy public debate. In this study all the cases of child sexual abuse referred for forensic examination in a 12 year period, a total of 368 cases, were systematically evaluated. In order to identify any trends that could be correlated to an impact of the 'Tønder-case', cases from 2000 to 2002 and cases from 2009 to 2011 underwent an in-depth analysis. In the 12 year period there was a significant increase in numbers of cases. In the subgroups, comprised of 113 cases meeting the inclusion criteria, we found a significant increase in the frequency of cases involving incest and systematic abuse, as well as an uncorrelated increase in the frequency of cases where children were placed in foster care prior to the examination. These results were countered by a significant decrease in the number cases police reported child sexual abuse in the same period. The possible impact that cases like the 'Tønder-case' and the following press coverage may have on disclosure and the handling of this type of case by authorities is discussed, as well as further perspectives of extensive press coverage.

Cri du Chat syndrome (CdCS) is a genetic syndrome caused by deletions in the short arm of chromosome 5. Although the main clinical features of CdCS are well known, the neurocognitive and behavioural characteristics of the phenotype are rarely described in detail in the literature. In this study, we analysed the main phenotypic features of CdCS from a parental perspective. A questionnaire was sent to 700 Brazilian families that were registered in the Brazilian Association of CdCS. The questions involved specific domains of CdCS, such as pregnancy and birth conditions, recurrence of the disease in the family, current major health problems, and aspects of cognitive development. In total, 73 questionnaires were completed: 44 females and 29 males, ranging from 9.5 months old to 40 years old (mean = 13.8 years; median = 12 years). Most of the parents noticed the typical cat-like cry at birth (94.4%). The age at diagnosis of CdCS ranged from the time of birth to 180 months (mean = 14 months; median = 6 months), while one case was diagnosed during pregnancy. In all of the cases, the diagnosis of CdCS was made by G-banding karyotype analysis. In 66.2% of the cases, the parents underwent cytogenetic investigation. A total of 52.1% of the parents answered that they did not remember what the recurrence risk of CdCS was in their family. The main health problems that were reported were as follows: swallowing problems (80.3%), feeding problems (80.3%), congenital heart disease (31.5%), spine abnormalities (28.8%), and neurological symptoms (20.5%), including seizures (11%). The behavioural problems that were reported were as follows: aggressive behaviour, stereotypies, anxiety, phobias, and genital manipulation/masturbation. Neurodevelopmental delay was reported in all of the cases. Independent walking was achieved in 72.2% of the patients. Approximately 50% of the patients never presented expressive language, and most of the patients are dependent on others for

The importance and protection of mangrove ecosystems has been recognized in Brazilian Federal law since 1965. Being protected in law, however, has not always guaranteed their protection in practice. Mangroves are found in coastal and estuarine locations, which are prime real estate for the growth of cities, ports and other economic activities important for Brazilian development. In this mini-review we introduce what mangroves are and why they are so important. We give a brief overview of the microbial diversity found in mangrove sediments and then focus on diversity studies from Brazilian mangroves. We highlight the breadth and depth of knowledge about mangrove microbial communities gained from studying Brazilian mangroves. We report on the exciting findings of molecular microbial ecology methods that have been very successfully applied to study bacterial communities. We note that there have been fewer studies that focus on fungal communities and that fungal diversity studies deserve more attention. The review ends with a look at how a combination of new molecular biology methods and isolation studies are being developed to monitor and conserve mangrove ecosystems and their associated microbial communities. These recent studies are having a global impact and we hope they will help to protect and re-establish mangrove ecosystems. PMID:24031949

A total of 165 sporotrichosis cases occurring in Nagasaki prefecture, and examined at Nagasaki University Hospital, were evaluated. Both males and females were equally affected, with no significant differences in the affected body regions. Lesions were frequently seen on the face (49 cases, 29.5%) and upper limbs (101 cases, 60.9%). The localised cutaneous type of sporotrichosis (105 cases, 62.9%) was much more frequent than the lymphocutaneous type (62 cases, 37.1%). The infection rate in patients over 50 years of age was 73.1%. The most frequent occupation among the patients was farming (52 cases, 37.4%), and 34 patients had a history of injury. Regarding the geographical distribution of sporotrichosis, 48 cases occurred in the Shimabara peninsula (31.2%) and this is much higher than expected for the population size. Before 1994, almost all sporotrichosis cases (112 cases, 96.5%) were treated with potassium iodide (KI). After 1995, the number of patients treated with KI decreased (nine cases, 23.1%), and itraconazole (ITZ) was used in 21 cases (59.0%) and terbinafine in six cases (15.3%). The time between ITZ and KI treatment and cure was 13.8 weeks and 12.5 weeks, respectively. All 116 cases, for which the outcome was known, were cured or improved. © 2013 Blackwell Verlag GmbH.

The ontology alignment was performed using a computer tool with algorithms to identify correspondences between concepts, which were organized and analyzed according to their presence or absence, their names, and their sibling, parent, and child classes. there were 2,682 concepts present in the ICNP® 2.0 Ontology that were missing in the Brazilian Ontology; 717 concepts present in the Brazilian Ontology were missing in the ICNP® 2.0 Ontology; and there were 215 pairs of matching concepts. it is believed that the correspondences identified in this study might contribute to the interoperability between the representations of nursing practice elements in ICNP®, thus allowing the standardization of nursing records based on this classification system.

Ancestry informative markers in Amerindians from Brazilian Amazon.

Ancestry informative markers (AIMs) are genetic loci with large frequency differences between the major ethnic groups and are very useful in admixture estimation. However, their frequencies are poorly known within South American indigenous populations, making it difficult to use them in admixture studies with Latin American populations, such as the trihybrid Brazilian population. To minimize this problem, the frequencies of the AIMs FY-null, RB2300, LPL, AT3-I/D, Sb19.3, APO, and PV92 were determined via PCR and PCR-RFLP in four tribes from Brazilian Amazon (Tikúna, Kashinawa, Baníwa, and Kanamarí), to evaluate their potential for discriminating indigenous populations from Europeans and Africans, as well as discriminating each tribe from the others. Although capable of differentiating tribes, as evidenced by the exact test of population differentiation, a neighbor-joining tree suggests that the AIMs are useless in obtaining reliable reconstructions of the biological relationships and evolutionary history that characterize the villages and tribes studied. The mean allele frequencies from these AIMs were very similar to those observed for North American natives. They discriminated Amerindians from Africans, but not from Europeans. On the other hand, the neighbor-joining dendrogram separated Africans and Europeans from Amerindians with a high statistical support (bootstrap = 0.989). The relatively low diversity (G(ST) = 0.042) among North American natives and Amerindians from Brazilian Amazon agrees with the lack of intra-ethnic variation previously reported for these markers. Despite genetic drift effects, the mean allelic frequencies herein presented could be used as Amerindian parental frequencies in admixture estimates in urban Brazilian populations.

Public health policy and the building up of a Brazilian medical identity.

PubMed

de Castro-Santos, L A

2005-12-01

Since George Herbert Mead studied "the social self" and the interactionists went further in distinguishing "images of self", a lecture on the building up of a Brazilian medical identity should try to focus on the patterns of self-images, presented images, and aspired-to images among the Brazilian medical elites during the First Republic (1889-1930). In no other period of Brazilian history were those "images" of professional identity so close--in contrast, later periods of Brazilian history witnessed an almost permanent "collision" or the clashing of such images among public health specialists. Oswaldo Cruz, Carlos Chagas, Artur Neiva and Belisário Pena are perhaps the best examples of successful careers as "sanitarians" (to recall John Duffy's historical work on luminaries before and after the "New Public Health" in the United States), and as important political actors during Brazil's First Republic. In light of the prominent political, policy-oriented, and scientific roles public health professionals played in Brazil, it is interesting to suggest that in large part such prominence resulted from the symbolic impact of the ideologies of sanitary reform on the political agenda of that period of Brazilian history. Where many studies look for personal rivalries and disputes around Chagas and Neiva as public figures, we may also see the importance of finding identity-building processes among public health specialists as an integrated group (e.g., trying to appear as "significant others" for the new generations of medical graduates in the country), regardless of existing rivalries. Cruz and Chagas, especially, were names with great impact in the Brazilian press (pro and con), a circumstance made possible largely by their easy and direct access to the Brazilian presidents Rodrigues Alves and Epitácio Pessoa, and, most clearly, by public health being one of Brazil's political priorities to find a place among the "civilized nations" of the world.

To compare the prevalence of pterygium and cataract in four indigenous populations of the Brazilian Amazonian rain forest (Arawak, Tukano, Maku, and Yanomami) with different ethnic and social behaviour backgrounds. A cross-sectional pterygium and cataract survey was performed in 624 adult Indians of the Brazilian rain forest belonging to four different ethnic groups. The Indians were classified according to their social behaviour in two groups: Arawak and Tukano (group 1) and Maku and Yanomami (group 2). Slit-lamp biomicroscopy was employed to examine the entire sample. All subjects were classified as 1 or 0 according to the presence or absence pterygium and cataract. Sex and age were also recorded. chi(2)-tests revealed that the prevalence of pterygium and cataract differed significantly between groups 1 and 2. For pterygia: 36.6% (97/265) and 5.0% (18/359), respectively (chi(2)=101.2, P<0.0001), and for cataracts: 24.5% (65/265) and 13.7% (49/359) respectively (chi(2)=12.09, P=0.0005). Gender was not associated with pterygium (P=0.1326) and cataract (P=0.2263) in both groups. Elderly subjects showed a significantly higher prevalence of cataract (P<0.0001). The prevalence of pterygia did not increase with age (P=0.8079) in both groups. Indians of group 1 have higher prevalence of pterygia and cataract than Indians of group 2. Social behaviour, especially the rate of sun exposure, appears to be the main factor for the different rates of pterygium and cataract displayed by these indigenous people of the Brazilian rain forest.

Epidemiology and treatment of psoriasis: a Brazilian perspective

Psoriasis is a chronic immune-mediated systemic disease that is influenced by genetic and environmental factors, is associated with comorbidities, and has a negative impact on the quality of life of affected individuals. The prevalence of psoriasis varies among different ethnic groups, but this topic has not been studied in Brazil to date. In this review, we evaluate the epidemiology and treatment of psoriasis from a Brazilian perspective. We focused on studies that involved Brazilian subjects. The prevalence of psoriasis in Brazil is estimated to be 2.5%, but no population study has been performed previously. Environmental factors, such as tropical climate, in association with genetic factors, such as miscegenation, may exert a beneficial impact on the course and frequency of psoriasis in Brazil. A number of studies have advanced our understanding of the cardiovascular, ophthalmic, and oral comorbidities that are associated with psoriasis. Concerns about biological therapy, such as endemic leprosy, human T-cell lymphotropic virus (HTLV), and tuberculosis infections, are discussed. The nonavailability of treatment options for psoriasis in the public health system contradicts the Brazilian Society of Dermatology guidelines, stimulating the judicialization of access to medicines in psoriasis care.

To determine sensitivity and specificity of cytologic examination used in a clinical setting. Retrospective study. 216 dogs, 44 cats, 4 horses, 2 ferrets, 1 llama, 1 rat, and 1 mouse. Records were reviewed of cases in which a cytologic diagnosis was followed by a surgical biopsy or postmortem examination within 3 days with subsequent histopathologic diagnosis. Diagnoses were compared for agreement at various levels, including complete agreement, partial agreement, no agreement, or no comparison possible because of insufficient or incorrect cytologic specimen. Levels of agreement were compared for different categories of lesions, including neoplastic, inflammatory, dysplastic-hyperplastic-other, and normal tissue. Additionally, levels of agreement for neoplastic lesions were categorized with regard to cell type, degree of malignancy, and location. Sensitivity and specificity of cytologic examination were calculated. At the level of general agreement (complete and partial agreement), the sensitivity of cytologic examination ranged from 33.3 to 66.1%, depending on the location of the lesion. Cytologic examination was most accurate when used to diagnose cutaneous and subcutaneous lesions and least accurate for diagnosis of liver lesions. Cytologic examination was most effective in diagnosis of neoplastic disease and least effective in diagnosis of dysplastic or hyperplastic conditions. Cytologic examination is a valuable diagnostic tool, although our results indicated lower accuracy than previously reported. False-negative results (missing a diagnosis) were far more common than false-positive results (categorizing a healthy animal as diseased): therefore, if the clinical index of suspicion is high, cytologic examination should be repeated or another technique should be selected to rule out the suspected condition.

I present distribution data of all Dactyloidae, Hoplocercidae, Iguanidae, Leiosauridae, Polychrotidae and Tropiduridae lizards known from the Brazilian Amazonia, totaling 40 species-level taxa, belonging to 11 genera. This represents four more species-level taxa than previously reported for these families. Data were based on the direct examination of 41,243 specimens deposited in three North American and eight Brazilian musea, including the main collections harboring Amazonian material. Most species (62.5%) are endemic to the Amazonia; non-endemic species are mainly associated with open dry (semideciduous) forest or open vegetation (savanna) enclaves in Amazonia, with a few exceptions. As a whole, seven taxa are widespread in Amazonia, one is restricted to eastern Amazonia, three to western Amazonia, five to northern Amazonia (either in part of it or widespread in the Guiana region), two to northwestern Amazonia, one to southern Amazonia, nine to southwestern Amazonia, and seven to the southern peripheral portion of Amazonia. Five species have unique distributions and five species have a distribution that is congruent with one of the areas of endemism (AE) recognized for other organisms (birds and primates). The first herpetological gazetteer for the Brazilian Amazonia with about 3,600 georeferenced localities was also produced.

We study the Brazilian Popular Music in a network perspective. We call the Brazilian Popular Music Network, BPMN, the graph where the vertices are the song writers and the links are determined by the existence of at least a common singer. The linking degree distribution of such graph shows power law and exponential regions. The exponent of the power law is compatible with the values obtained by the evolving network algorithms seen in the literature. The average path length of the BPMN is similar to the correspondent random graph, its clustering coefficient, however, is significantly larger. These results indicate that the BPMN forms a small-world network.

Hundreds of different human skeletal disorders have been characterized at molecular level and a growing number of resembling dysplasias with orthologous genetic defects are being reported in dogs. This study describes a novel genetic defect in the Brazilian Terrier breed causing a congenital skeletal dysplasia. Affected puppies presented severe skeletal deformities observable within the first month of life. Clinical characterization using radiographic and histological methods identified delayed ossification and spondyloepiphyseal dysplasia. Pedigree analysis suggested an autosomal recessive disorder, and we performed a genome-wide association study to map the disease locus using Illumina’s 22K SNP chip arrays in seven cases and eleven controls. A single association was observed near the centromeric end of chromosome 6 with a genome-wide significance after permutation (pgenome  = 0.033). The affected dogs shared a 13-Mb homozygous region including over 200 genes. A targeted next-generation sequencing of the entire locus revealed a fully segregating missense mutation (c.866C>T) causing a pathogenic p.P289L change in a conserved functional domain of β-glucuronidase (GUSB). The mutation was confirmed in a population of 202 Brazilian terriers (p = 7,71×10−29). GUSB defects cause mucopolysaccharidosis VII (MPS VII) in several species and define the skeletal syndrome in Brazilian Terriers. Our results provide new information about the correlation of the GUSB genotype to phenotype and establish a novel canine model for MPS VII. Currently, MPS VII lacks an efficient treatment and this model could be utilized for the development and validation of therapeutic methods for better treatment of MPS VII patients. Finally, since almost one third of the Brazilian terrier population carries the mutation, breeders will benefit from a genetic test to eradicate the detrimental disease from the breed. PMID:22815736

The study of the body measurements of Brazilian women used the Kinect Body Imaging system for 3D body scanning. The result of the study aims to meet the needs of the apparel industry for accurate measurements. Data was statistically treated using the IBM SPSS 23 system, with 95% confidence (P<0,05) for the inferential analysis, with the purpose of grouping the measurements in sizes, so that a smaller number of sizes can cover a greater number of people. The sample consisted of 101 volunteers aged between 19 and 62 years. A cluster analysis was performed to identify the main body shapes of the sample. The results were divided between the top and bottom body portions; For the top portion, were used the measurements of the abdomen, waist and bust circumferences, as well as the height; For the bottom portion, were used the measurements of the hip circumference and the height. Three sizing systems were developed for the researched sample from the Abdomen-to-Height Ratio - AHR (top portion): Small (AHR < 0,52), Medium (AHR: 0,52-0,58), Large (AHR > 0,58) and from the Hip-to-Height Ratio - HHR (bottom portion): Small (HHR < 0,62), Medium (HHR: 0,62-0,68), Large (HHR > 0,68).

Food safety is a strategic topic entailing not only national public health aspects but also competitiveness in international trade. An important component of any food safety program is the control and monitoring of residues posed by certain substances involved in food production. In turn, a National Residue Control Plan (NRCP) relies on an appropriate laboratory network, not only to generate analytical results, but also more broadly to verify and co-validate the controls built along the food production chain. Therefore laboratories operating under a NRCP should work in close cooperation with inspection bodies, fostering the critical alignment of the whole system with the principles of risk analysis. Beyond producing technically valid results, these laboratories should arguably be able to assist in the prediction and establishment of targets for official control. In pursuit of analytical excellence, the Brazilian government has developed a strategic plan for Official Agricultural Laboratories. Inserted in a national agenda for agricultural risk analysis, the plan has succeeded in raising laboratory budget by approximately 200%, it has started a rigorous program for personnel capacity-building, it has initiated strategic cooperation with international reference centres, and finally, it has completely renewed instrumental resources and rapidly triggered a program aimed at full laboratory compliance with ISO/IEC 17025 requirements.

Body checking is considered an expression of an excessive preoccupation with appearance. The first aim of this study was to evaluate the psychometric properties of a Brazilian Portuguese version of the Body Checking Questionnaire (BCQ). Additionally, we wanted to examine the questionnaire's associations with body avoidance behaviour, body mass index, dietary habits, and the intensity, frequency, and length of physical exercise. Finally, we also examined the differences between the total BCQ score and the individual BCQ factor scores. Differences between active and sedentary persons and between non-dieters and those on weight-loss diets were also analyzed. For the psychometric study, 546 female public university students from four different courses were surveyed. Two minor samples of university students and eating disorders women were also recruited. In the second part of the study, 403 women were recruited from weight-loss programs, gyms, and a university. All participants were verbally invited to participate in the research and voluntarily took part. Confirmatory factor analysis showed a good fit to the original model of the Brazilian BCQ that retained all 23 items. Satisfactory evidence of construct validity and internal consistency were also generated through analysis of factor loadings, t-values, Cronbach's alpha, and construct reliability tests. The results also showed associations among body checking and body avoidance, body satisfaction, social anxiety, body mass index, and the frequency and intensity of physical exercise. Significant differences were found between non-dieters and weight-loss dieters for all BCQ factors and the total BCQ score. For physically active and sedentary persons, a significant difference was only observed for idiosyncratic checking behaviour. In conclusion, the BCQ appears to be a valid and reliable scale for Brazilian research, and the associations and differences found in this study suggest that women at gyms and especially in

Recent information from various sources suggests that a new illicit drug, called "oxi", is being spread across Brazil. It would be used in the smoked form and it would look like to crack cocaine: usually small yellowish or light brown stones. As fully released in the media, "oxi" would differ from crack cocaine in the sense that crack would contain carbonate or bicarbonate salts whereas "oxi" would include the addition of calcium oxide and kerosene (or gasoline). In this context, this work presents a chemical profiling comparative study between "oxi" street samples seized by the Civil Police of the State of Acre (CP/AC) and samples associated with both international and interstate drug trafficking seized by the Brazilian Federal Police in Acre (FP/AC). The outcome of this work assisted Brazilian authorities to stop inaccurate and alarmist releases on this issue. It may be of good use by the forensic community in order to better understand matters in their efforts to guide local law enforcement agencies in case such claims reach the international illicit market.

The number of Brazilian periodicals listed in the Index Medicus dropped from 70 in 1964 to 15 in 1983, or 78%, while the total number of listed periodicals from other countries fell only 11%. The total number of articles published in Brazil on Chagas' disease, schistosomiasis, leishmaniasis, leprosy, malaria, and filariasis, and listed in the Index Medicus did not change significantly between 1965 and 1982, because, with the exception of the journal O Hospital, the Brazilian periodicals that published 74% of all articles on those diseases remained listed throughout the period considered. The predominant subjects in articles on endemic diseases were Chagas' disease and schistosomiasis, and in the later years there was a tendency to index more articles on basic than on applied research. The number of articles on Chagas' disease published by Brazilian authors directly in foreign journals increased considerably during the latter decade. Analysis of all the data together suggests that the developed countries select a specific portion of the Brazilian output of biomedical literature--which is kept listed in secondary and international publications or published directly in foreign journals--while another portion of the same output gradually loses visibility on the international scene.

HLA-F is a non-classical major histocompatibility complex (MHC) gene. It codes class Ib MHC molecules with restricted distribution and less nucleotide variations than MHC class Ia genes. Of the 22 alleles registered on the IMGT database only four alleles encode for proteins that differ in their primary structure. To estimate genotype and allele frequencies, this study targeted on known protein coding regions of the HLA-F gene. Genotyping was performed by Sequence Base Typing (SBT). The sample was composed by 199-unrelated bone marrow donors from the Brazilian Bone Marrow Donor Registry (REDOME), Euro-Brazilians, from Southern Brazil. About 1673 bp were analyzed. The most frequent allele was HLA-F*01:01 (87.19%), followed by HLA-F*01:03 (12.31%), HLA-F*01:02 (0.25%) and HLA-F*01:04 (0.25%). Significant linkage disequilibrium (LD) was verified between HLA-F and HLA classes I and II alleles. This is the first study regarding HLA-F polymorphisms in a Euro-Brazilian population contributing to the Southern Brazilian genetic characterization. © 2014 John Wiley & Sons A/S.

The FBI's DRUGFIRETM system is a nationwide computerized networked image database of ballistic forensic evidence. This evidence includes images of cartridge cases and bullets obtained from both crime scenes and controlled test firings of seized weapons. Currently, the system is installed in over 80 forensic labs across the country and has enjoyed a high degree of success. In this paper, we discuss some of the issues and methods associated with providing a front-end semi-automated image capture system that simultaneously satisfies the often conflicting criteria of the many human examiners visual perception versus the criteria associated with optimizing autonomous digital image correlation. Specifically, we detail the proposed processing chain of an intelligent image capture system (IICS), involving a real- time capture 'assistant,' which assesses the quality of the image under test utilizing a custom designed neural network.

There are many different studies that contribute to the global picture of the ethnic heterogeneity in Brazilian populations. These studies use different types of genetic markers and are focused on the comparison of populations at different levels. In some of them, each geographical region is treated as a single homogeneous population, whereas other studies create different subdivisions: political (e.g., pooling populations by State), demographic (e.g., urban and rural), or ethnic (e.g., culture, self-declaration, or skin colour). In this study, we performed an enhanced reassessment of the genetic ancestry of ~ 1,300 Brazilians characterised for 46 autosomal Ancestry Informative Markers (AIMs). In addition, 798 individuals from twelve Brazilian populations representing the five geographical macro-regions of Brazil were newly genotyped, including a Native American community and a rural Amazonian community. Following an increasing North to South gradient, European ancestry was the most prevalent in all urban populations (with values up to 74%). The populations in the North consisted of a significant proportion of Native American ancestry that was about two times higher than the African contribution. Conversely, in the Northeast, Center-West and Southeast, African ancestry was the second most prevalent. At an intrapopulation level, all urban populations were highly admixed, and most of the variation in ancestry proportions was observed between individuals within each population rather than among population. Nevertheless, individuals with a high proportion of Native American ancestry are only found in the samples from Terena and Santa Isabel. Our results allowed us to further refine the genetic landscape of Brazilians while establishing the basis for the effective application of an autosomal AIM panel in forensic casework and clinical association studies within the highly admixed Brazilian populations.

This paper deals with the molecular investigation of Waardenburg syndrome (WS) in a sample of 49 clinically diagnosed probands (most from southeastern Brazil), 24 of them having the type 1 (WS1) variant (10 familial and 14 isolated cases) and 25 being affected by the type 2 (WS2) variant (five familial and 20 isolated cases). Sequential Sanger sequencing of all coding exons of PAX3, MITF, EDN3, EDNRB, SOX10 and SNAI2 genes, followed by CNV detection by MLPA of PAX3, MITF and SOX10 genes in selected cases revealed many novel pathogenic variants. Molecular screening, performed in all patients, revealed 19 causative variants (19/49 = 38.8%), six of them being large whole-exon deletions detected by MLPA, seven (four missense and three nonsense substitutions) resulting from single nucleotide substitutions (SNV), and six representing small indels. A pair of dizygotic affected female twins presented the c.430delC variant in SOX10, but the mutation, imputed to gonadal mosaicism, was not found in their unaffected parents. At least 10 novel causative mutations, described in this paper, were found in this Brazilian sample. Copy-number-variation detected by MLPA identified the causative mutation in 12.2% of our cases, corresponding to 31.6% of all causative mutations. In the majority of cases, the deletions were sporadic, since they were not present in the parents of isolated cases. Our results, as a whole, reinforce the fact that the screening of copy-number-variants by MLPA is a powerful tool to identify the molecular cause in WS patients. Copyright © 2018 Elsevier Masson SAS.

Archaea in Natural and Impacted Brazilian Environments

PubMed Central

2016-01-01

In recent years, archaeal diversity surveys have received increasing attention. Brazil is a country known for its natural diversity and variety of biomes, which makes it an interesting sampling site for such studies. However, archaeal communities in natural and impacted Brazilian environments have only recently been investigated. In this review, based on a search on the PubMed database on the last week of April 2016, we present and discuss the results obtained in the 51 studies retrieved, focusing on archaeal communities in water, sediments, and soils of different Brazilian environments. We concluded that, in spite of its vast territory and biomes, the number of publications focusing on archaeal detection and/or characterization in Brazil is still incipient, indicating that these environments still represent a great potential to be explored.

I present distribution data of all geckos (Gekkonidae, Phyllodactylidae and Sphaerodactylidae) known from the Brazilian Amazonia, totaling 19 species, belonging to nine genera. This represents six more taxa than previously reported for these families. Data were based on the direct examination of 23,094 specimens deposited in three North American and eight Brazilian museums. Most species (68.4%) are endemic to the Amazonia; non-endemic species are mainly associated with open dry (semideciduous) forest or open vegetation (savanna) enclaves in Amazonia. As a whole, three taxa are widespread in Amazonia, two are restricted to eastern Amazonia, two to western Amazonia, three to northern Amazonia (either widespread or restriced to parts of the Guiana region), one to southern Amazonia, one to southwestern Amazonia, and three to the southern peripheral portion of Amazonia. Additionally, four species have unique distributions and four species have a distribution that is congruent with one of the areas of endemism recognized for other organisms (birds and primates), of which two occur in the area of endemism of Guiana, one in Inambari, and one in Tapajós.

This study examined whether holidays, geographical area and donation type (community versus replacement) has any impact on the fluctuation of donations. Methods The numbers of blood donations from 2007 through 2010 in three Brazilian Retrovirus Epidemiological Donor Study II (REDS-II) participating centers were analyzed according to the week of donation. The weeks were classified as holiday or non-holiday. To compare donations performed during holiday versus non-holiday weeks, tabulations and descriptive statistics for weekly donations by blood center were examined and time series analysis was conducted. Results The average weekly number of donations varied according to the blood center and type of week. The average number of donations decreased significantly during Carnival and Christmas and increased during the Brazilian National Donor Week. The fluctuation was more pronounced in Recife and Belo Horizonte when compared to São Paulo and higher among community donors. Conclusion National bank holidays affect the blood supply by reducing available blood donations. Blood banks should take into account these oscillations in order to plan local campaigns, aiming at maintaining the blood supply at acceptable levels. PMID:24106441

It has been proposed that homeless street girls are more likely to be from dysfunctional families and exhibit psychological distress than homeless street boys, reflecting cultural factors that result in differential norms for male and female behavior. The current analysis examined whether male and female street youth in a mid-sized Brazilian city differed in their family circumstances and day-to-day functioning on the street. The opportunity sample consisted of 33 male (mean age 14.3, range 10-17 years) and 33 female (mean age 14.6, range 11-18 years) street youth who participated in a sentence completion task and structured interview examining family experiences and ability to meet daily needs on the street. Consistent with the cultural hypothesis, girls described more negative family backgrounds than boys (e.g., they were more likely to have left home because of conflict or abuse, and reported more negative relationships with their parents). However, girls' functioning on the street was similar to, and in some cases more positive than, that of boys (e.g., fewer girls reported police violence and begging to earn money). The few gender differences that emerged in this study offer little support for the cultural hypothesis. The findings make sense if local factors, such as services available for male and female youth and public response to street youth, are considered. It appears that street youth differ in their experiences depending on local circumstances, highlighting the need for caution in generalizing about the situation of street youth in different countries.

Objective: Research suggests that alcoholic beverage advertisements may have an adverse effect on teenagers and young adults, owing to their vulnerability to suggestive message content. This study was designed to evaluate perceived violations of the content guidelines of the Brazilian alcohol marketing self-regulation code, based on ratings of the five most popular beer advertisements broadcast on television in the summer of 2005–2006 and during the 2006 FIFA (Fédération Internationale de Football Association) World Cup games. Method: Five beer advertisements were selected from a previous study showing that they were perceived to be highly appealing to a sample of Brazilian teenagers. These advertisements were evaluated by a sample of Brazilian high school students using a rating procedure designed to measure the content of alcohol advertisements covered in industry self-regulation codes. Results: All five advertisements were found to violate multiple guidelines of the Brazilian code of marketing self-regulation. The advertisement with the greatest number of violations was Antarctica's “Male Repellent,” which was perceived to violate 11 of the 16 guidelines in the code. Two advertisements had nine violations, and one had eight. The guidelines most likely to be violated by these advertisements were Guideline 1, which is aimed at protecting children and teenagers, and Guideline 2, which prohibits content encouraging excessive and irresponsible alcoholic beverage consumption. Conclusions: The five beer advertisements rated as most appealing to Brazilian teenagers were perceived by a sample of the same population to have violated numerous principles of the Brazilian self-regulation code governing the marketing of alcoholic beverages. Because of these numerous perceived code violations, it now seems important for regulatory authorities to submit industry marketing content to more systematic evaluation by young people and public health experts and for researchers

Adiponectin complexes composition in Japanese-Brazilians regarding their glucose tolerance status

PubMed Central

2013-01-01

Background Adiponectin circulates in different multimer complexes comprised of low molecular weight trimeric form (LMW), hexamer of middle molecular weight (MMW) and high molecular weight multimers (HMW). In Japanese-Brazilians, a population with high prevalence of glucose metabolism disturbances, we examined the associations of total adiponectin and its multimers with diabetes mellitus. Methods Two study groups were examined: 26 patients with diabetes mellitus (DM,14 women and 12 men, aged 55.3 ± 8.6 years) and 27 age-matched control subjects with normal glucose tolerance (NGT,12 women and 15 men, aged 54.0 ± 9.2 years). Results We found no significant differences in total [NGT: 6.90 ug/ml (4.38-13.43); DM: 5.38 ug/ml (3.76-8.56), p = 0.35], MMW [NGT:2.34 ug/ml (1.38-3.25); DM: 1.80 ug/ml (1.18-2.84), p = 0.48] or LMW adiponectin [NGT: 2.07 ug/ml (1.45-3.48), DM: 2.93 ug/ml (1.78-3.99), p = 0.32] between groups. In contrast, HMW adiponectin levels were significantly lower in patients with DM [TGN: 2.39 ug/ml (1.20-4.75); DM: 1.04 ug/ml (0.42-1.60), p = 0.001]. A logistic regression analysis was done to identify independent associations with diabetes mellitus. The results showed that HOMA-IR and HMW adiponectin in women were independently associated with diabetes mellitus. Conclusion The current investigation demonstrates that in Japanese-Brazilians HMW adiponectin is selectively reduced in individuals with type 2 diabetes, while no differences were found in MMW and LMW adiponectin isoforms.

Lower urinary tract symptoms (LUTS) and erectile dysfunction (ED) are common problems in middle-aged and older men. Recently, epidemiologic studies have shown significant associations between severity of LUTS and male sexual dysfunction. We analyzed the role of prostate enlargement, LUTS, and prostate specific antigen (PSA) levels in the erectile function of Brazilian men who underwent prostate cancer (PCa) screening. We analyzed data from 1,008 consecutive patients enrolled in a PCa screening program. Benign prostatic hyperplasia (BPH) was defined as a prostate weight greater than 30 g as defined by digital rectal examination. For statistical analysis, we used the chi-squared and analysis of variance tests. The odds ratios (OR) for correlation of ED with prostate volume LUTS and PSA were estimated using logistic regression models. The American Urological Association (AUA) symptom score for LUTS and the International Index of Erectile Function. Mean patient age was 61.2 years (45-87) and median PSA value was 1.9 ng/mL. BPH was identified in 48.5% of patients. Mild, moderate, and severe LUTS were found in 52.3%, 30.9%, and 16.8% of cases, respectively. ED was classified as absent, mild, mild to moderate, moderate, and severe in 18.6%, 23.1%, 18.6%, 15.2%, and 24.5%, respectively. While only 5.4% of the patients with no ED presented severe LUTS, this finding was observed in 27.1% of patients with severe ED (P < 0.001). Univariate logistic regression analysis demonstrated that age, prostate volume, AUA symptom score, and PSA levels were significant predictors of ED. However, when controlled for patient age, only LUTS remained as an independent predictor of ED. Controlling for patient age, LUTS are independent risk factors for the development of ED among Brazilian men who undergo PCa screening.

To determine the influence of reproductive history on the prevalence of obesity in Brazilian women and the possible modifying effect of socioeconomic variables on the association between parity and excess weight. A retrospective analysis of complex sample data collected as part of the 2006 Brazilian National Survey on Demography and Health, which included a group representative of women of childbearing age in Brazil was conducted. The study included 11 961 women aged 20 to 49 years. The association between the study factor (parity) and the outcome of interest (obesity) was tested using logistic regression analysis. The adjusted effect of parity on obesity was assessed in a multiple regression model containing control variables: age, family purchasing power, as defined by the Brazilian Association of Research Enterprises (ABEP), schooling, and health care. Significance level was set at below 0.05. The prevalence of obesity in the study population was 18.6%. The effect of parity on obesity was significant (P for trend < 0.001). Unadjusted analysis showed a positive association of obesity with parity and age. Family purchase power had a significant odds ratio for obesity only in the unadjusted analysis. In the adjusted model, this variable did not explain obesity. The present findings suggest that parity has an influence on obesity in Brazilian women of childbearing age, with higher prevalence in women vs. without children.

The enormous amount of information available in cell biology has created a challenge in selecting the core concepts we should be teaching our undergraduates. One way to define a set of essential core ideas in cell biology is to analyze what a specific cell biology community is teaching their students. Our main objective was to analyze the cell biology content currently being taught in Brazilian universities. We collected the syllabi of cell biology courses from public universities in Brazil and analyzed the frequency of cell biology topics in each course. We also compared the Brazilian data with the contents of a major cell biology textbook. Our analysis showed that while some cell biology topics such as plasma membrane and cytoskeleton was present in ∼100% of the Brazilian curricula analyzed others such as cell signaling and cell differentiation were present in only ∼35%. The average cell biology content taught in the Brazilian universities is quite different from what is presented in the textbook. We discuss several possible explanations for these observations. We also suggest a list with essential cell biology topics for any biological or biomedical undergraduate course. The comparative discussion of cell biology topics presented here could be valuable in other educational contexts. © 2017 The Authors.

Objective. To describe the redesigned assessment plan for a patient safety and informatics course and assess student pharmacist performance and perceptions. Methods. The final examination of a patient safety course was redesigned from traditional multiple choice and short answer to team-based, open-ended, and case-based. Faculty for each class session developed higher level activities, focused on developing key skills or attitudes deemed essential for practice, for a progressive patient case consisting of nine activities. Student performance and perceptions were analyzed with pre- and post-surveys using 5-point scales. Results. Mean performance on the examination was 93.6%; median scores for each assessed course outcome ranged from 90% to 100%. Eighty-five percent of students completed both surveys. Confidence performing skills and demonstrating attitudes improved for each item on post-survey compared with pre-survey. Eighty-one percent of students indicated the experience of taking the examination was beneficial for their professional development. Conclusion. A team, case-based examination was associated with high student performance and improved self-confidence in performing medication safety-related skills. PMID:28970618

The Brazilian's National Institute for Space Research (INPE), in collaboration with the Engineering School of Lorena/University of São Paulo (EEL/USP), the Federal University of Minas Gerais (UFMG), and the Brazilian's National Laboratory for Astrophysics (LNA), is developing a solar vector magnetograph and visible-light imager to study solar processes through observations of the solar surface magnetic field. The Brazilian Experimental Solar Telescope is designed to obtain full disk magnetic field and line-of-sight velocity observations in the photosphere. Here we discuss the system requirements and the first design review of the instrument. The instrument is composed by a Ritchey-Chrétien telescope with a 500 mm aperture and 4000 mm focal length. LCD polarization modulators will be employed for the polarization analysis and a tuning Fabry-Perot filter for the wavelength scanning near the Fe II 630.25 nm line. Two large field-of-view, high-resolution 5.5 megapixel sCMOS cameras will be employed as sensors. Additionally, we describe the project management and system engineering approaches employed in this project. As the magnetic field anchored at the solar surface produces most of the structures and energetic events in the upper solar atmosphere and significantly influences the heliosphere, the development of this instrument plays an important role in advancing scientific knowledge in this field. In particular, the Brazilian's Space Weather program will benefit most from the development of this technology. We expect that this project will be the starting point to establish a strong research program on Solar Physics in Brazil. Our main aim is to progressively acquire the know-how to build state-of-art solar vector magnetograph and visible-light imagers for space-based platforms.

The admixed Brazilian population shows high levels of genetic variability, which resulted from the contribution of three main ethnicities, Amerindian, European, and African. However, due to its huge territory, admixing has been asymmetrical, i.e., the relative contribution from each ethnicity has been unequal in the five geopolitical regions of the country. The aim of this study was to describe genetic variability using a panel of short-tandem repeats on the X chromosome (X-STR) in order to perform a comprehensive evaluation of the usefulness of such markers for forensic purposes in Brazil. Twelve X-STR (DXS9895, DXS7132, DXS6800, DXS9898, DXS6789, DXS7133, GATA172D05, DXS7130, HPRTB, GATA31E08, DXS7423, and DXS10011) were chosen and tested in a sample of 2,234 individuals belonging to 16 out of the 27 Brazilian States, representing all of its five geopolitical regions. No markers showed significant deviation from the Hardy-Weinberg equilibrium, even when analyses were partitioned to represent geopolitical regions. Genetic diversity per locus ranged from 67% (DSX7133) to 95% (DXS10011), and the State of Ceará showed the highest average genetic diversity (79% for all 12 X-STR markers). Considering the Brazilian population as a whole, the power of discrimination of the 12 X-STR panel in females (PDF) was 0.999999999999994, while the power of discrimination in males (PDM) was 0.9999999969. Such high values suggest the potential of that panel to be used in forensic applications and relatedness tests among individuals. Comparisons among the Brazilian populations investigated revealed significant differences when they were compared among each other, a pattern that was maintained when additional populations from Europe and Latin America were compared to Brazilians. Our results highlight the need and usefulness of specific genetic database for forensic purposes in Brazilian populations.

The purpose of this study was to perform the cultural adaptation of the Brazilian version of the Vocal Fatigue Index (VFI). Two Brazilian bilingual speech-language pathologists (SLP) translated the original version of the VFI in English into Portuguese. The translations were reviewed by a committee of five voice specialist SLPs resulting in the final version of the instrument. A third bilingual SLP back-translated this final version and the same committee reviewed the differences from its original version. The final Portuguese version of the VFI, as in the original English version, was answered on a categorical scale of 0-4 indicating the frequency they experience the symptoms: 0=never, 1=almost never, 2=sometimes, 3=almost always, and 4=always. For cultural equivalence of the Portuguese version, the option "not applicable" was added to the categorical scale and 20 individuals with vocal complaints and dysphonia completed the index. Questions considered "not applicable" would be disregarded from the Brazilian version of the protocol; no question had to be removed from the instrument. The Brazilian Portuguese version was entitled "Índice de Fadiga Vocal - IFV" and features 19 questions, equivalent to the original instrument. Of the 19 items, 11 were related with tiredness of voice and voice avoidance, five concerned physical discomfort associated with voicing, and three were related to improvement of symptoms with rest or lack thereof. The Brazilian version of the VFI presents cultural and linguistic equivalence to the original instrument. The IFV validation into Brazilian Portuguese is in progress.

The objective of this study was to investigate whether decreased baseline adiponectin levels are an independent risk factor for development of glucose intolerance in a population-based study of Japanese-Brazilians, a group with one of the highest prevalence rates of diabetes worldwide. We examined 210 Japanese-Brazilians (97 male and 113 female, aged 56.7+/-10.1 years) with normal glucose tolerance (NGT). Plasma adiponectin, insulin, fasting and 2-h plasma glucose and lipid profile were evaluated at baseline and also at 7-year follow-up. Plasma adiponectin levels were significantly lower in glucose intolerance progressors compared with subjects who remained NGT. By increasing tertiles of adiponectin, the frequencies of subjects who progressed to glucose intolerance were 40%, 33% and 27% and the frequencies of subjects who remained NGT were 13%, 35% and 52% (chi2=15.8, p=0.001). Logistic regression analyses showed that adiponectin levels (OR for the highest versus lowest tertile: 0.31; 95% CI: 0.12-0.84, p=0.021), male sex (OR: 2.61, 95% CI: 1.21-5.65, p=0.015), fasting plasma glucose (0R: 3.05, 95% CI: 1.35-6.91, p=0.008) and waist circumference (OR: 1.04, 95% CI: 1.00-1.08, p=0.046) were independent risk factors for the progression to glucose intolerance. In conclusion, low plasma levels of adiponectin is one of several independent predictors of glucose intolerance in a Japanese-Brazilian population.

To determine the association of single-nucleotide polymorphisms (SNPs) in genes related to craniofacial development, which were previously identified as susceptibility signals for nonsyndromic oral clefts, in Brazilians with nonsyndromic cleft lip and/or palate (NSCL/P). The SNPs rs748044 (TNP1), rs1106514 (MSX1), rs28372960, rs15251 and rs2569062 (TCOF1), rs7829058 (FGFR1), rs1793949 (COL2A1), rs11653738 (WNT3), and rs242082 (TIMP3) were assessed in a family-based transmission disequilibrium test (TDT) and a structured case-control analysis based on the individual ancestry proportions. The SNPs were initially analyzed by TDT, and polymorphisms showing a trend toward excess transmission were subsequently studied in an independent case-control sample. The study sample consisted of 189 case-parent trios of nonsyndromic cleft lip with or without cleft palate (NSCL±P), 107 case-parent trios of nonsyndromic cleft palate (NSCP), 318 isolated samples of NSCL±P, 189 isolated samples of NSCP, and 599 healthy controls. Association of alleles with NSCL/P pathogenesis. Preferential transmission of SNPs rs28372960 and rs7829058 in NSCL±P trios and rs11653738 in NSCP trios (P = .04) were observed, although the structured case-control analysis did not confirm these associations. The haplotype T-C-C formed by TCOF1 SNPs rs28372960, rs15251, and rs2569062 was more frequently transmitted from healthy parents to NSCL±P offspring, but the P value (P = .01) did not withstand Bonferroni correction for multiple tests. With the modest associations, our results do not support the hypothesis that TNP1, MSX1, TCOF1, FGFR1, COL2A1, WNT3, and TIMP3 variants are risk factors for nonsyndromic oral clefts in the Brazilian population.

Using the results of dozens of interviews with key actors involved in tobacco control policymaking, we examine these actors' perceptions of threats to tobacco control policy efforts from international economic policies on trade and investment. We also evaluate, from a legal perspective, the genuine threats that exist or potential challenges that economic policies may pose to the Brazilian government's public health efforts. We find that most actors did not perceive these economic policies as a major threat to tobacco control. Objectively, we found that some threats do exist. For example, Brazil's attempt to ban most tobacco additives and flavorings continues to met resistance at the World Trade Organization.

Male recombination in Brazilian populations of Drosophila ananassae.

Goñi, Beatriz; Matsuda, Muneo; Tobari, Yoshiko N

2016-07-01

With few exceptions, spontaneous crossing over does not normally occur in male Drosophila. Drosophila ananassae males show considerable amounts of crossing over. In wild males of D. ananassae from Asian (2008) and Brazilian populations (1986 and 2007) variable frequencies of meiotic crossing over, estimated from chiasmata counts, suggested the existence of factors controlling male crossing over in these populations. To corroborate for such prediction, we present data on spontaneous recombination in F1 males of D. ananassae heterozygous for chromosomes of the same Brazilian populations (1986) and marker chromosomes using three testers stocks. Mean recombination value was low, although high variability existed between individual frequencies. Recombination frequencies between lines in each tester stock were not significantly different, excepting when the 3ple-px and 3ple-cy testers were compared (p < 0.05). These two testers differ in respect to the regional distribution of crossovers. The occurrence of recombination in chromosomes 2 and 3 in F1 males tested with e(65) se; bri ru was not related, suggesting they are under independent genetic control. Our data are consistent with proposed genetic factors controlling male crossing over in the tester stocks and to the presence of enhancers and suppressors of male crossing over segregating in the Brazilian populations (1986).

OBJECTIVE To analyze the influence from context characteristics in the control of tuberculosis in prisons, and the influence from the program implementation degrees in observed effects. METHODS A multiple case study, with a qualitative approach, conducted in the prison systems of two Brazilian states in 2011 and 2012. Two prisons were analyzed in each state, and a prison hospital was analyzed in one of them. The data were submitted to a content analysis, which was based on external, political-organizational, implementation, and effect dimensions. Contextual factors and the ones in the program organization were correlated. The independent variable was the program implementation degree and the dependent one, the effects from the Tuberculosis Control Program in prisons. RESULTS The context with the highest sociodemographic vulnerability, the highest incidence rate of tuberculosis, and the smallest amount of available resources were associated with the low implementation degree of the program. The results from tuberculosis treatment in the prison system were better where the program had already been partially implemented than in the case with low implementation degree in both cases. CONCLUSIONS The implementation degree and its contexts – external and political-organizational dimensions – simultaneously contribute to the effects that are observed in the control of tuberculosis in analyzed prisons.

Multiple organizations produce guidance documents that provide opportunities to harmonize quality practices for diagnostic testing. The International Organization for Standardization ISO 15189 standard addresses requirements for quality in management and technical aspects of the clinical laboratory. One technical aspect addresses the complexities of the pre-examination phase prior to diagnostic testing. The Committee for Molecular Diagnostics of the International Federation for Clinical Chemistry and Laboratory Medicine (also known as, IFCC C-MD) conducted a survey of international molecular laboratories and determined ISO 15189 to be the most referenced guidance document. In this review, the IFCC C-MD provides case-based examples illustrating the value of select pre-examination processes as these processes relate to molecular diagnostic testing. Case-based examples in infectious disease, oncology, inherited disease and pharmacogenomics address the utility of: 1) providing information to patients and users, 2) designing requisition forms, 3) obtaining informed consent and 4) maintaining sample integrity prior to testing. The pre-examination phase requires extensive and consistent communication between the laboratory, the healthcare provider and the end user. The clinical vignettes presented in this paper illustrate the value of applying select ISO 15189 recommendations for general laboratory to the more specialized area of Molecular Diagnostics.

2014-01-01

The scope of this article is to identify and analyze the factors that influence the adoption of ICT tools in experiments with bioinformatics at the Brazilian Cancer Institute (INCA). It involves a descriptive and exploratory qualitative field study. Evidence was collected mainly based on in-depth interviews with the management team at the Research Center and the IT Division. The answers were analyzed using the categorical content method. The categories were selected from the scientific literature and consolidated in the Technology-Organization-Environment (TOE) framework created for this study. The model proposed made it possible to demonstrate how the factors selected impacted INCA´s adoption of bioinformatics systems and tools, contributing to the investigation of two critical areas for the development of the health industry in Brazil, namely technological innovation and bioinformatics. Based on the evidence collected, a research question was posed: to what extent can the alignment of the factors related to the adoption of ICT tools in experiments with bioinformatics increase the innovation capacity of a Brazilian biopharmaceutical organization?

To investigate the association between fat mass and obesity-associated (FTO) gene polymorphisms rs8050136C>A and rs9939609T>A, and transcription factor 7-like 2 (TCF7L2) gene polymorphisms rs12255372G>T and rs7903146C>T, in a sample group of pregnant Euro-Brazilian women with or without gestational diabetes mellitus (GDM). Subjects were classified as either healthy pregnant control (n=200) or GDM (n=200) according to the 2010 criteria of the American Diabetes Association. The polymorphisms were genotyped using fluorescent probes (TaqMan®). All groups were in the Hardy-Weinberg equilibrium. The genotype and allele frequencies of the examined polymorphisms did not exhibit significant difference (P>0.05) between the groups. In the healthy and GDM pregnant women groups, the A-allele frequencies (95% CI) of FTO polymorphisms rs8050136 and rs9939609 were 39% (34-44%); 38% (33-43%) and 40% (35-45%); 41% (36-46%), respectively; and the T-allele frequencies of TCF7L2 polymorphisms rs12255372 and rs7903146 were 30% (26-35%), 32% (27-37%) and 29% (25-34%), 36% (31-41%), respectively. The examined polymorphisms were not associated with GDM in the Euro-Brazilian population studied. Copyright © 2015 The Canadian Society of Clinical Chemists. Published by Elsevier Inc.

Xeroderma pigmentosum (XP) is a rare autosomal recessive disorder characterized by DNA repair defects that cause photophobia, sunlight-induced cancers, and neurodegeneration. Prevalence of germline mutations in the nucleotide excision repair gene XPA vary significantly in different populations. No Brazilian patients have been reported to carry a germline mutation in this gene. In this study, the germline mutational status of XPA was determined in Brazilian patients exhibiting major clinical features of XP syndrome. The study was conducted on 27 unrelated patients from select Brazilian families. A biallelic inactivating transition mutation c.619C>T (p.Arg207Ter) was identified in only one patient with a history of neurological impairment and mild skin abnormalities. These findings suggest that XP syndrome is rarely associated with inherited disease-causing XPA mutations in the Brazilian population. Additionally, this report demonstrates the effectiveness of genotype-phenotype correlation as a valuable tool to guide direct genetic screening. PMID:25913378

Propolis-based therapeutic agents represent this potential for the development of new drugs in dental care. The aim of a clinical-cohort study was to determine the influence of application of toothpaste enriched with Brazilian extract of propolis (EEP) on health status of oral cavity. Laboratory analysis was conducted in order to assess the chemical composition of EEP including total phenolic compounds, the DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity, ABTS radical cation scavenging activity, and FRAP assay. Clinical research involved two groups of subjects comprising 32 adult patients, with assessment based on the preliminary evaluation of the state of their marginal periodontium. The investigation of oral health indices API, OHI, and SBI and microbiological examination of oral microflora were also carried out. Results obtained indicated time-dependent microbial action of EEP at 50 mg/L concentration, with antimicrobial activity against Gram-positive bacteria. The total decrease of API, OHI, and SBI mean values was observed. Hygienic preparations with 3% content of Brazilian ethanol extract of green propolis (EEP) efficiently support removal of dental plaque and improve the state of marginal periodontium. PMID:23861699

Methodological study that aimed to adapt the Satisfaction with Appearance Scale (SWAP) into Brazilian Portuguese language and to assess the validity, the reliability and the dimensionality of the adapted version in a sample of Brazilian burn victims. We carried out the adaptation process according to the international literature. Construct validity was assessed by correlating the adapted version of SWAP scores with depression (Beck Depression Index), self-esteem (Rosenberg Self-Esteem Scale), health-related quality of Life (Short Form Health Survey-36) and health status of burn victims (Burn Specific Health Scale-Revised), and with gender, total body surface area burned, and visibility of the scars. We tested dimensionality using Exploratory Factor Analysis (EFA) and the reliability by means of Cronbach's alpha. Participants were 106 adult burned patients. The correlations between the Brazilian version of the SWAP scores and the correlated construct measures varied from moderate to strong (r=.30-.77). The participants who perceived their burn sequelae was visible reported being more dissatisfied with their body image than the participants who answered that their scars would not be visible (p<.001). Cronbach's alpha for the adapted version was 0.88 and the item-total correlation varied from moderate to strong (r=.35-.73). The EFA resulted in three factors with a total explained variance percentage of 63.2%. The Brazilian version of the SWAP was valid and reliable for use with Brazilian burn victims.

O'Dougherty, Maureen

2013-03-01

Brazil's rate of cesarean deliveries is among the highest in the world and constitutes the majority of childbirths in private hospitals. This study examines ways middle-class Brazilian women are exercising agency in this context. It draws from sociolinguistics to examine narrative structure and dramatic properties of 120 childbirth narratives of 68 low- to high-income women. Surgical delivery constituted 62% of the total. I focus on 20 young middle-class women, of whom 17 had C-sections. Doctors determined mode of childbirth pre-emptively or appeared to accommodate women's wishes, while framing the scenario as necessitating surgical delivery. The women strove to imbue C-section deliveries with value and meaning through staging, filming, familial presence, attempting induced labor, or humanized childbirth. Their stories indicate that class privilege does not lead to choice over childbirth mode. The women nonetheless struggle over the significance of their agency in childbirth. © 2013 by the American Anthropological Association.

An evaluation of overnight fixation to facilitate neuropathological examination in Coroner's autopsies: our experience of over 200 cases.

PubMed

2013-01-01

Following recent changes in Coroner's Rules, there has been a desire to examine brains at the time of autopsy, rather than after a prolonged period of immersion fixation. Examination of the fresh brain at postmortem can yield unsatisfactory results where detailed histological examination is required. We aim to provide a compromise, where detailed examination of the brain is possible, without the requirement for prolonged fixation, interference with funeral arrangements and delay in the Coronial process. A retrospective audit of over 200 neuropathology cases requested by HM Coroner for the East Riding of Yorkshire between 2007 and 2010 was performed. The cases consisted of full neuropathology autopsies (n=212) and brains referred by general pathology colleagues (n=26). Of the 238 brains examined, approximately half (n=109) of the brains were sectioned fresh in the mortuary. The remaining brains (n=129) were immersion fixed overnight in 20% formalin prior to cutting and sampling for histology (n=127). The median time for reporting was 31 days (range 1-167; n=101) for brains requiring histology. This equates to a median turnaround time of 1 month for a neuropathological autopsy requiring detailed histology. In all cases, the report was prepared and available to HM Coroner in advance of the Inquest. This method provides reliable histological diagnoses in neuropathological autopsies and does not interfere with funeral arrangements for bereaved families following deaths falling under Coronial jurisdiction. In all cases, the body could be released to relatives, at Coroner's discretion, within two working days of the autopsy.

As marine ecosystems are influenced by global and regional processes, standardized information on community structure has become crucial for assessing broad-scale responses to natural and anthropogenic disturbances. Extensive biogeographic provinces, such as the Brazilian Province in the southwest Atlantic, present numerous theoretical and methodological challenges for understanding community patterns on a macroecological scale. In particular, the Brazilian Province is composed of a complex system of heterogeneous reefs and a few offshore islands, with contrasting histories and geophysical-chemical environments. Despite the large extent of the Brazilian Province (almost 8,000 kilometers), most studies of shallow benthic communities are qualitative surveys and/or have been geographically restricted. We quantified community structure of shallow reef habitats from 0° to 27°S latitude using a standard photographic quadrat technique. Percent cover data indicated that benthic communities of Brazilian reefs were dominated by algal turfs and frondose macroalgae, with low percent cover of reef-building corals. Community composition differed significantly among localities, mostly because of their macroalgal abundance, despite reef type or geographic region, with no evident latitudinal pattern. Benthic diversity was lower in the tropics, contrary to the general latitudinal diversity gradient pattern. Richness peaked at mid-latitudes, between 20°S to 23°S, where it was ~3.5-fold higher than localities with the lowest richness. This study provides the first large-scale description of benthic communities along the southwestern Atlantic, providing a baseline for macroecological comparisons and evaluation of future impacts. Moreover, the new understanding of richness distribution along Brazilian reefs will contribute to conservation planning efforts, such as management strategies and the spatial prioritization for the creation of new marine protected areas.

Abstract Fruit fly sexual behaviour is directly influenced by chemical and non-chemical cues that play important roles in reproductive isolation. The chemical profiles of pheromones and cuticular hydrocarbons (CHs) of eight fruit fly populations of the Andean, Brazilian-1 and Brazilian-3 morphotypes of the Anastrepha fraterculus cryptic species complex originating from Colombia (four populations) and Brazil (four populations) were analysed using two-dimensional gas chromatography with mass spectrometric detection. The resulting chemical diversity data were studied using principal component analyses. Andean morphotypes could be discriminated from the Brazilian-1 and Brazilian-3 morphotypes by means of male-borne pheromones and/or male and female CH profiles. The Brazilian-1 and Brazilian-3 morphotypes were found to be monophyletic. The use of chemical profiles as species- and sex-specific signatures for cryptic species separations is discussed.

Prostate cancer still represents a major cause of morbidity, and still about 20% of men with the disease are diagnosed or will progress to the advanced stage without the possibility of curative treatment. Despite the recent advances in scientific and technological knowledge and the availability of new therapies, there is still considerable heterogeneity in the therapeutic approaches for metastatic prostate cancer. This article presents a summary of the I Brazilian Consensus on Advanced Prostate Cancer, conducted by the Brazilian Society of Urology and Brazilian Society of Clinical Oncology. Experts were selected by the medical societies involved. Forty issues regarding controversial issues in advanced disease were previously elaborated. The panel met for consensus, with a threshold established for 2/3 of the participants. The treatment of advanced prostate cancer is complex, due to the existence of a large number of therapies, with different response profiles and toxicities. The panel addressed recommendations on preferred choice of therapies, indicators that would justify their change, and indicated some strategies for better sequencing of treatment in order to maximize the potential for disease control with the available therapeutic arsenal. The lack of consensus on some topics clearly indicates the absence of strong evidence for some decisions. Copyright® by the International Brazilian Journal of Urology.

This study aimed to compare the self-esteem of Brazilian adolescents with epilepsy and Brazilian adolescents without this condition and the correlations between self-esteem of these adolescents with depression and anxiety symptoms. Study participants were 101 adolescents of both sexes, aged 10-19years old, from elementary and high school education. Fifty patients diagnosed with uncomplicated epilepsy attending the pediatric epilepsy clinic of University Hospital composed the case group. The other fifty-one adolescents without this diagnosis were attending public schools in Campinas-SP region. The instruments used were: identification card with demographics and epilepsy data, Multidimensional Self-Esteem Scale, Beck Depression Inventory and Inventory of State-Trait Anxiety - IDATE. A statistically significant result was found in the Responsibility Self-esteem Dimension favoring the control group. Significant correlations between self-esteem scores and anxiety and depression symptoms were also found. The development of a chronic disease such as epilepsy leads to a change in the way the individual perceives himself and the social environment he is inserted, influencing his behavior. The way people with epilepsy experience their seizures is a subjective measure that will control his/her well-being. Childhood and adolescence form the basis for a healthy emotional development; thus, our results show the importance of studying how subjective variables relate to the physical aspects of a chronic disease in these life stages.

Flood Frequency Analysis Under Non-stationarity Conditions: the Case of Southern Brazilian Hydroelectric Power Plants

Bartiko, Daniel; Chaffe, Pedro; Bonumá, Nadia

Floods may be strongly affected by climate, land-use, land-cover and water infrastructure changes. However, it is common to model this process as stationary. This approach has been questioned, especially when it involves estimate of the frequency and magnitude of extreme events for designing and maintaining hydraulic structures, as those responsible for flood control and dams safety. Brazil is the third largest producer of hydroelectricity in the world and many of the country's dams are located in the Southern Region. So, it seems appropriate to investigate the presence of non-stationarity in the affluence in these plants. In our study, we used historical flood data from the Brazilian National Grid Operator (ONS) to explore trends in annual maxima in river flow of the 38 main rivers flowing to Southern Brazilian reservoirs (records range from 43 to 84 years). In the analysis, we assumed a two-parameter log-normal distribution a linear regression model was applied in order to allow for the mean to vary with time. We computed recurrence reduction factors to characterize changes in the return period of an initially estimated 100 year-flood by a log-normal stationary model. To evaluate whether or not a particular site exhibits positive trend, we only considered data series with linear regression slope coefficients that exhibit significance levels (p<0,05). The significance level was calculated using the one-sided Student's test. The trend model residuals were analyzed using the Anderson-Darling normality test, the Durbin-Watson test for the independence and the Breusch-Pagan test for heteroscedasticity. Our results showed that 22 of the 38 data series analyzed have a significant positive trend. The trends were mainly in three large basins: Iguazu, Uruguay and Paranapanema, which suffered changes in land use and flow regularization in the last years. The calculated return period for the series that presented positive trend varied from 50 to 77 years for a 100 year

Abstract A second assessment of Brazilian Trichoptera species records is presented here. A total of 625 species were recorded for Brazil. This represents an increase of 65.34% new species recorded during the last decade. The Hydropsychidae (124 spp.), followed by the Hydroptilidae (102 spp.) and Polycentropodidae (97 spp.), are the families with the greatest richness recorded for Brazil. The knowledge on Trichoptera biodiversity in Brazil is geographically unequal. The majority of the species is recorded for the southeastern region. PMID:25349524

To identify factors associated with timely treatment of malaria in the Brazilian Amazon. Malaria, despite being treatable, has proven difficult to control and continues to be an important public health problem globally. Brazil accounted for almost half of the 427 000 new malaria cases notified in the Americas in 2013. This was a cross-sectional study using secondary data on all notified malaria cases for the period from 2004 - 2013. Timely treatment was considered to be all treatment started within 24 hours of symptoms onset. Multivariate logistic regression was used to identify independent factors associated with timely treatment. The proportion of cases starting treatment on a timely basis was 41.1%, tending to increase in more recent years (OR = 1.40; 95%CI: 1.37 - 1.42 in 2013). Furthermore, people starting within < 24 hours were more likely to: reside in the states of Rondônia (OR = 1.50; 95%CI: 1.49 - 1.51) or Acre (OR = 1.53; 95%CI: 1.55 - 1.57); be 0 - 5 years of age (OR = 1.39; 95%CI: 1.34 - 1.44) or 6 - 14 years of age (OR = 1.34; 95%CI: 1.32 - 1.36); be indigenous (OR = 1.41; 95%CI: 1.37 - 1.45); have a low level of schooling (OR = 1.20; 95%CI: 1.19 - 1.22); and be diagnosed by active detection (OR = 1.39; 95%CI: 1.38 - 1.39). In the Brazilian Amazon area, individuals were more likely to have timely treatment of malaria if they were young, residing in Acre or Rondônia states, have little schooling, and be identified through active detection. Identifying groups vulnerable to late treatment is important for preventing severe cases and malaria deaths.

Case-control studies are important in developing clinical and public health knowledge. The STROBE statement (STrengthening the Reporting of OBservational Studies in Epidemiology) was developed to establish a checklist of items that should be included in articles reporting observational studies. Our aim was to analyze whether the psychiatric case-control articles published in Brazilian journals with CAPES Qualis rating B1/B2 in 2009 conformed with the STROBE statement. Descriptive study on psychiatric papers published in Brazilian journals, within the Postgraduate Medical Program on Psychiatry, at Universidade Federal do Rio Grande do Sul. All psychiatric case-control studies from Brazilian Qualis B1/B2 journals of psychiatry, neurology and public health in 2009 were analyzed. The four most specific items of the STROBE statement were used to evaluate whether these studies fitted within the case-control parameters: 1) selection of cases and controls; 2) controlling for bias; 3) statistical analysis; and 4) presentation of results. Sixteen case-control studies were identified, of which eleven (68.75%) were in psychiatry-focused journals. From analysis using the STROBE statement, all of the articles conformed with item 1; two (12.5%) completely conformed with item 2; none completely conformed with item 3; and only three (18.8%) conformed with item 4. The case-control studies analyzed here did not completely conform with the four STROBE statement items for case-control design. In view of the inadequate methodology of the published studies, these findings justify focusing on research and methodology and expanding the investigations on adherence of studies to their designs.

The purpose of this study was to improve the quality of items on the Korean Nursing Licensing Examination by developing and evaluating case-based items that reflect integrated nursing knowledge. We conducted a cross-sectional observational study to develop new case-based items. The methods for developing test items included expert workshops, brainstorming, and verification of content validity. After a mock examination of undergraduate nursing students using the newly developed case-based items, we evaluated the appropriateness of the items through classical test theory and item response theory. A total of 50 case-based items were developed for the mock examination, and content validity was evaluated. The question items integrated 34 discrete elements of integrated nursing knowledge. The mock examination was taken by 741 baccalaureate students in their fourth year of study at 13 universities. Their average score on the mock examination was 57.4, and the examination showed a reliability of 0.40. According to classical test theory, the average level of item difficulty of the items was 57.4% (80%-100% for 12 items; 60%-80% for 13 items; and less than 60% for 25 items). The mean discrimination index was 0.19, and was above 0.30 for 11 items and 0.20 to 0.29 for 15 items. According to item response theory, the item discrimination parameter (in the logistic model) was none for 10 items (0.00), very low for 20 items (0.01 to 0.34), low for 12 items (0.35 to 0.64), moderate for 6 items (0.65 to 1.34), high for 1 item (1.35 to 1.69), and very high for 1 item (above 1.70). The item difficulty was very easy for 24 items (below -2.0), easy for 8 items (-2.0 to -0.5), medium for 6 items (-0.5 to 0.5), hard for 3 items (0.5 to 2.0), and very hard for 9 items (2.0 or above). The goodness-of-fit test in terms of the 2-parameter item response model between the range of 2.0 to 0.5 revealed that 12 items had an ideal correct answer rate. We surmised that the low reliability of the

The marine nematodes usually comprise free-living species, although a few are parasitic. However, several cases of free-living nematodes found accidentally in the digestive tract of certain vertebrates, especially fishes, have sometimes been recorded and categorized as pseudoparasites. In the present work, two species of marine fishes, the rhomboid crappie, Diapterus rhombeus, and the silvered crappie, Eucinostomus argenteus (Perciformes: Gerreidae), from Angra dos Reis on the coast of Rio de Janeiro (Brazil) were examined. Seven species of free-living marine nematodes were found in the digestive tract of these fish. Several of these species remain unknown as free-living forms in Brazil. The combination of the fish feeding strategies and the poor preservation of the body of the nematode specimens found could indicate that these nematodes are pseudoparasites, appearing in the fishes' digestive tracts through accidental ingestion and thereafter surviving for brief periods of time. Descriptions, illustrations and tables of measurements are provided for all species. Six of these species (Croconema torquens, Dorylaimopsis pellucida, Oncholaimellus labiatus, Parodontophora breviamphida, Prooncholaimus ornatus, Trissonchulus latus) have been reported for the first time from the Brazilian coast.

To determine the prevalence of refractive errors and their distribution according to age and sex in a Brazilian population. This population-based cross-sectional study involved 7654 Brazilian inhabitants of nine municipalities of Sao Paulo State, Brazil, between March 2004 and July 2005. Participants aged >1 year were selected using a random, stratified, household cluster sampling technique, excluding individuals with previous refractive or cataract surgery. Myopia was defined as spherical equivalent (SE) ≤-0.5D, high myopia as SE ≤-3.0D, hyperopia as SE ≥+0.5D, high hyperopia as SE ≥+3D, astigmatism as ≤-0.5DC and anisometropia as ≥1.0D difference between eyes. Age, sex, complaints and a comprehensive eye examination including cycloplegic refraction test were collected and analysed using descriptive analysis, univariate and multivariate methods. The prevalence of astigmatism was 59.7%, hyperopia 33.8% and myopia was 25.3%. Astigmatism had a progressive increase with age. With-the-rule (WTR) axes of astigmatism were more frequently observed in the young participants and the against-the-rule (ATR) axes were more frequent in the older subjects. The onset of myopia occurred more frequently between the 2nd and 3rd decades of life. Anisometropia showed a prevalence of 13.2% (95% CI 12.4-13.9; p < 0.001). There was an association between age and all types of refractive error and hyperopia was also associated with sex. Hyperopia was associated with WTR axes (odds ratio 0.73; 95% CI: 0.6-0.8; p < 0.001) and myopia with ATR axes (odds ratio 0.66; 95% CI: 0.6-0.8; p < 0.001). Astigmatism was the most prevalent refractive error in a Brazilian population. There was a strong relationship between age and all refractive errors and between hyperopia and sex. WTR astigmatism was more frequently associated with hyperopia and ATR astigmatism with myopia. The vast majority of participants had low-grade refractive error, which favours planning aimed at correction of

Background Chromobacterium violaceum is a free-living bacterium able to survive under diverse environmental conditions. In this study we evaluate the genetic and physiological diversity of Chromobacterium sp. isolates from three Brazilian ecosystems: Brazilian Savannah (Cerrado), Atlantic Rain Forest and Amazon Rain Forest. We have analyzed the diversity with molecular approaches (16S rRNA gene sequences and amplified ribosomal DNA restriction analysis) and phenotypic surveys of antibiotic resistance and biochemistry profiles. Results In general, the clusters based on physiological profiles included isolates from two or more geographical locations indicating that they are not restricted to a single ecosystem. The isolates from Brazilian Savannah presented greater physiologic diversity and their biochemical profile was the most variable of all groupings. The isolates recovered from Amazon and Atlantic Rain Forests presented the most similar biochemical characteristics to the Chromobacterium violaceum ATCC 12472 strain. Clusters based on biochemical profiles were congruent with clusters obtained by the 16S rRNA gene tree. According to the phylogenetic analyses, isolates from the Amazon Rain Forest and Savannah displayed a closer relationship to the Chromobacterium violaceum ATCC 12472. Furthermore, 16S rRNA gene tree revealed a good correlation between phylogenetic clustering and geographic origin. Conclusion The physiological analyses clearly demonstrate the high biochemical versatility found in the C. violaceum genome and molecular methods allowed to detect the intra and inter-population diversity of isolates from three Brazilian ecosystems.

The genus Kogia, which comprises only two extant species, Kogia sima and Kogia breviceps, represents one of the least known groups of cetaceans in the global ocean. In some coastal regions, however, stranding events of these species have been relatively common over the last decades. Stranding provides the opportunity to investigate the biology of these cetaceans and to explore the epidemiological aspects associated with the mortality of the organisms found on the beach. A number of disturbances (including pelagic fisheries, chemical pollution, boat strikes, and noise pollution) have been confirmed to pose a particular threat to the Kogia species. However, no study has yet investigated potential relationships between environmental conditions and stranding events. Here we analyse how a collection of environmental, physical, and biological variables, such as wind, sea surface temperature (SST), water depth, and chlorophyll-a, correlate to Kogia stranding events along the Brazilian coast. The results of our statistical analyses suggest that K. sima is more likely found in warm tropical waters, which provide an explanation for the high frequency of stranding in northeastern Brazilian coast. In contrast, K. breviceps appears to have a preference for temperate and productive waters. Wind speed results to be also an important factor for predicting Kogia strandings in Brazilian coast. Additionally, literature information in combination with our own data and analyses of stomach contents confirms that oceanic cephalopods constitute the primary nutritional source of both Kogia species. By using the available information as a qualitative proxy for habitat preference and feeding ecology, our study provides a novel and comprehensive assessment of Kogia stranding data in relation to environmental conditions along the Brazilian coast.

The main objective of this study was to evaluate the prevalence of emergencies in dental practices and the prepared-ness and the training experience in cardiopulmonary resuscitation (CPR) of Brazilian dentists in dealing with emergencies. The volunteer participants in the study were 498 Brazilian dentists who were present at the 27th International Congress of Dentistry in São Paulo. The most prevalent emergency was presyncope (reported by 54.20 percent of respondents), followed by orthostatic hypotension (44.37 percent), moderate allergic reactions (16.86 percent), hypertensive crisis (15.06 percent), asthma (15.06 percent), syncope (12.65 percent), angina (6.82 percent), convulsion (6.22 percent), hypoglycemia (5.62 percent), hyperventilation crisis (5.22 percent), choking (2.20 percent), and cerebrovascular accident (0.8 percent). Anaphylaxis, myocardial infarction, and cardiac arrest were the rarest emergencies, reported by only 0.4, 0.2, and 0.2 percent of dentists, respectively. Only 41 percent of the dentists judged themselves capable to diagnose the cause of an emergency during a dental visit. The majority responded that they would be capable of performing initial treatment of presyncope, syncope, orthostatic hypotension, convulsion, and choking. However, most of them felt unable to treat anaphylaxis, myocardial infarction, or cardiac arrest. Further, the majority felt unable to perform CPR or undertake an intravenous injection. It was concluded that the most prevalent medical emergencies in dental practice of Brazilian dentists are presyncope and orthostatic hypotension. The occurrence of life-threatening medical emergencies like anaphylaxis, myocardial infarction, cardiac arrest, and cerebrovascular accident is rare. Brazilian dentists are not fully prepared to manage medical emergencies and have insufficient experience training in CPR.

Revisiting the hierarchy of urban areas in the Brazilian Amazon: a multilevel approach

Costa, Sandra; Brondízio, Eduardo

2012-01-01

The Legal Brazilian Amazon, while the largest rainforest in the world, is also a region where most residents are urban. Despite close linkages between rural and urban processes in the region, rural areas have been the predominant focus of Amazon-based population-environment scholarship. Offering a focus on urban areas within the Brazilian Amazon, this paper examines the emergence of urban hierarchies within the region. Using a combination of nationally representative data and community based surveys, applied to a multivariate cluster methodology (Grade of Membership), we observe the emergence of sub-regional urban networks characterized by economic and political inter-dependency, population movement, and provision of services. These networks link rural areas, small towns, and medium and large cities. We also identify the emergence of medium-size cities as important nodes at a sub-regional level. In all, the work provides insight on the proposed model of ‘disarticulated urbanization’ within the Amazon by calling attention to the increasing role of regional and sub-regional urban networks in shaping the future expansion of land use and population distribution in the Amazon. We conclude with a discussion of implications for increasing intra-regional connectivity and fragmentation of conservation areas and ecosystems in the region. PMID:23129877

A total of 120 candidates passed the practical exam. Of these, 116 took the written qualification exam. In the end, 107 were approved, 74 (69.1%) of whom were temporary public nurses, 59 (55.1%) Anna Nery Nursing School alumni, and 10 among the first 20 twenty became involved with the Brazilian Association of Nursing later. although the exam legitimized the meritbased culture in the staff selection in the area of Brazilian nursing, egalitarian criteria were mitigated, especially regarding the grades applied to different kinds of exams. This resulted in a significant number of temporary nurses approved.

The profiles of proteins present in the exoantigens of Brazilian Sporothrix schenckii isolates were studied and compared by electrophoresis (SDS-PAGE). Thirteen isolates from five different regions of Brazil (1,000 to 2,000 km apart) and ten from a more limited region (200 to 400 km apart within the state of São Paulo) were cultured in Sabouraud, M199 and minimum (MM) media. Qualitative and quantitative differences in the expression of proteins, which varied according to the medium and the isolate, were observed. Fractions with the same MW but varying in intensity were detected, as well as fractions present in 1 isolate but absent in others. Dendrograms were constructed and isolates grouped based on the fractions obtained, irrespective of the intensity. The results showed that Brazilian S. schenckii isolates express different protein profiles, a feature also present in isolates from a more restricted region. The exoantigens were found to have a maximum of 15 protein fractions, ranging in MW from 19-220 KDaltons depending on the medium used for the cultures. These data show the great heterogeneity of Brazilian S. schenckii protein expression.

Tabak, Benjamin M.

2007-11-01

In this paper a simple test for detecting bilinearity in a stochastic unit root process is used to test for the presence of nonlinear unit roots in Brazilian equity shares. The empirical evidence for a set of 53 individual stocks, after adjusting for GARCH effects, suggests that for more than 66%, the hypothesis of unit root bilinearity is accepted. Therefore, the dynamics of Brazilian share prices is in conformity with this type of nonlinearity. These nonlinearities in spot prices may emerge due to the sophistication of the derivatives market.

Efficiency determinants and capacity issues in Brazilian for-profit hospitals.

This paper reports on the use of different approaches for assessing efficiency of a sample of major Brazilian for-profit hospitals. Starting out with the bootstrapping technique, several DEA estimates were generated, allowing the use of confidence intervals and bias correction in central estimates to test for significant differences in efficiency levels and input-decreasing/output-increasing potentials. The findings indicate that efficiency is mixed in Brazilian for-profit hospitals. Opportunities for accommodating future demand appear to be scarce and strongly dependent on particular conditions related to the accreditation and specialization of a given hospital.

A Brazilian ranch worker with encephalitis and flaccid paralysis was evaluated in the regional Acute Encephalitis Syndromic Surveillance Program. This was the first Brazilian patient who met the Centers for Disease Control and Prevention (CDC) confirmation criteria for West Nile virus disease. Owing to the overlapping of neurological manifestations attributable to several viral infections of the central nervous system, this report exemplifies the importance of human acute encephalitis surveillance. The syndromic approach to human encephalitis cases may enable early detection of the introduction of unusual virus or endemic occurrence of potentially alarming diseases within a region.

The objective of Brazilian Eratosthenes Project is the development and application of teaching training actions according the ``docent autonomy" concept to basic Astronomy Education. Argentina coordinates the project in South America, but Brazil works in this project since 2010 with the theme ``Projeto Eratóstenes Brasil" in the homepage: http://sites.google.com/site/projetoerato. Two schools measure a sticks shadow and communicate their results. After, they calculate an average radius of Earth. The stick (gnomon) should stay in vertical position in the leveled ground. Since 2010, the project received hundreds of Brazilian schools with different experiments that were constructed with autonomy, because our site doesn't show some itinerary pre-ready to elaborate the experiments. To collect data for our research, we will use interviews via Skype with the teachers. These data are useful to researches about Science Education area and the Teaching Formation. Teaching professional practice could change and we see modifications in the teachers work, what depends of their realities and context. This project intents to respect the docent autonomy. This autonomy to responsible modifications during continued formation is called ``activist formative model" according Langhi & Nardi (Educação em Astronomia: repensando a formação de professores. São Paulo: Escrituras Editora, 2012). This project discusses about researches in Astronomy Education - still extreme rare in Brazil, when we compare with other areas in Science Education. We believe that actions like this could motivate the students to learn more Astronomy. Furthermore, this national action can be a rich source of data to investigations about teaching formation and scientific divulgation.

Fishing for gaps in science: a bibliographic analysis of Brazilian freshwater ichthyology from 1986 to 2005.

2010-06-01

To investigate Brazilian freshwater ichthyology, from 1986 to 2005, a bibliometric analysis was conducted using abstracts downloaded from The Web of Science database searching for the keywords 'fish', 'pisces', 'teleostei' and the address field having the word 'Brazil'. The results of this study showed that Brazilian freshwater ichthyology publications have been increasing during the study period. This process is a consequence of a series of investments that the Brazilian Government has made. Furthermore, data analyses identified scientific areas where there was a lack of scientific knowledge (e.g. studies of species threatened with extinction and certain hydrologic basins). Research institutions from the north-east and northern region of Brazil had the lowest participation in scientific productivity, which was a reflection of their regions poorer economic situation. This study showed that scientific productivity in Brazilian ichthyology was a direct reflection of state investment in research. Furthermore, data in this study follow expected statistical probabilities, for example, fishes from the most diverse families were the most studied. Thus, the study shows that great progress has been made by Brazilian ichthyologists in the last 20 years; however, due to the mega diversity of fishes in Brazil, much remains to be done if many species are to become known to science and to be saved from extinction. This it seems will depend on continued and further investment by Brazilian Government funding agencies, as Brazilian ichthyologists have demonstrated their capacity to generate high quality information about their study species.

The present study evaluates how five sectors of two Brazilian hospitals have implemented lean healthcare concepts in their operations. The main characteristics of the implementation process are analyzed in the present study: the motivational factor for implementation, implementation time, form (consultancy or internal), team (hospital and consultants), lean implementation continuity/sustainability, lean healthcare tools and methods implemented, problems/improvement opportunities, lean healthcare barriers faced during the implementation process, and critical factors that affected the implementation and the results obtained in each case. The case studies indicate that reducing patient lead times and costs and making financial improvements were the primary factors that motivated lean healthcare implementation in the hospitals studied. Several tools and methods were used in the cases studied, especially value stream mapping and DMAIC. The barriers found in both hospitals are primarily associated with the human factor. Additionally, the results obtained after implementation were analyzed and improvements in financial aspects, productivity and capacity, and lead time reduction of the analyzed sectors were observed. Further, this study also exhibited four propositions elaborated from the results obtained from the cases that highlighted barriers and challenges to lean healthcare implementation in developing countries. Two of these barriers are hospital organizational structure (and, consequently, how the senior management works with medical staff), and outsourcing hospital activities. This study also concluded that the initialization and maintenance of lean healthcare implementation rely heavily on external support because lean healthcare subject knowledge is not yet available in the healthcare organization, which represents a challenge.

Despite significant progress, there is still a gender gap in science all over the world, especially at senior levels. Some progressive countries are recognizing the need to address barriers to gender equality in order to retain their best scientists and innovators, and ensure research excellence and social and economic returns on the investment made by taxpayers each year on training women scientists. We investigated the gender distribution of: (i) the productivity scholarship (PS) holders of the Brazilian National Council for Scientific and Technological Development (Conselho Nacional de Desenvolvimento Científico e Tecnológico, CNPq, N = 13,625), (ii) the members of the Brazilian Academy of Science (Academia Brasileira de Ciências, ABC, N = 899), and (iii) the amount of funding awarded for top quality research ("Universal" Call of CNPq, N = 3,836), between the years of 2013 and 2014. Our findings show evidence for gender imbalances in all the studied indicators of Brazilian science. We found that female scientists were more often represented among PS holders at the lower levels of the research ranking system (2). By contrast, male scientists were more often found at higher levels (1A and 1B) of PS holders, indicating the top scientific achievement, both in "Engineering, Exact Sciences, Earth Sciences", and "Life Sciences". This imbalance was not found in Humanities and Social Sciences. Only 14% of the ABC members were women. Humanities and Applied Social Sciences had a relatively low representation of women in the Academy (3.7%) compared to Engineering, Exact and Earth Sciences: 54.9% and Life Sciences: 41.4%. Finally, female scientists obtained significantly more funding at the lower level of the research ranking system (2), whereas male scientists obtained significantly more funding at the higher levels (1A and 1B). Our results show strong evidence of a gender imbalance in Brazilian science. We hope that our findings will be used to stimulate reforms that

The knowledge of octocorals occurring in Brazilian deep waters is still lacking, with only a few studies conducted so far, most of which focused on large-scale marine habitats characterization. Primnoidae are common and characteristic of seamounts and deepwater coral banks, often providing habitat for other marine species. Although primnoids occur in all ocean basins, only Primnoella and Plumarella species were recorded along the Brazilian coast before this study. Primnoid specimens were obtained through dredging and remotely operated vehicles (ROV) sampling, collected by research projects conducted off the Brazilian coast, between 15 and 34°S. Taxonomic assessment resulted in 5 new records of Primnoidae genera in Brazil: Calyptrophora, Candidella, Dasystenella, Narella and Thouarella. The occurrences of Narella-off Salvador and Vitória, and in Campos Basin (935-1700 m), and Calyptrophora-in Campos Basin (1059-1152 m), are herein reported for the first time in the South Atlantic. Calyptrophora microdentata was previously known in Lesser Antilles, New England and Corner Rise Seamounts, between 686 and 2310 m. Candidella imbricata geographical distribution includes Western and Eastern Atlantic (514-2063 m and 815-2139 m, respectively), being registered herein in Campos Basin, between 1059 and 1605 m. Dasystenella acanthina collected off Rio Grande do Sul state (810 m) and occurs also off Argentina and Southern Ocean, between 150 and 5087 m. Plumarella diadema, which type locality is off São Sebastião, Brazil, has its geographical range extended northwards, occurring in Campos Basin (650 m). Thouarella koellikeri previously known for Patagonia and Antartic Peninsula, is registered for the off Brazil for the first time, in Campos Basin and off São Sebastião (609-659 m). There is a lot of work yet to be done in terms of taxonomic knowledge of Brazilian deep-sea octocorals. Research projects focusing on the investigations, including ROV sampling, of other

AIM To determine the main visual symptoms in a Brazilian population sample, associated to refractive errors (REs) and spectacle need to suggest priorities in preventive programs. METHODS A cross-sectional study was conducted in nine counties of the southeast region of Brazil, using a systematic sampling of households, between March 2004 and July 2005. The population was defined as individuals aged between 1 and 96y, inhabitants of 3600 residences to be evaluated and 3012 households were included, corresponding to 8010 subjects considered for participation in the survey, of whom 7654 underwent ophthalmic examinations. The individuals were evaluated according their demographic data, eye complaints and eye examination including the RE and the need to prescribe spectacles according to age. Statistical analysis was performed using SPSS software package and descriptive analysis using 95% confidence intervals (P<0.05). RESULTS The main symptom detected was asthenopia, most frequent in the 2nd and 3rd decades of life, with a significant decline after the 4th decade. Astigmatism was the RE most associated with asthenopia. Reduced near vision sight was more frequent in those ≥40y with a progressive decline thereafter. Spectacles were most frequently required in subjects of ≥40 years of age. CONCLUSION The main symptom related to the vision was asthenopia and was associated to astigmatism. The greatest need for spectacles prescription occurred after 40's, mainly to correct near vision. Subjects of ≥40 years old were determined to be at high risk of uncorrected REs. These observations can guide intervention programs for the Brazilian population. PMID:27990372

To investigate the prevalence of non-orthogonal astigmatism among normal and keratoconic Brazilian and Chinese populations. Topography data were obtained using the Pentacam High Resolution (HR) system ® from 458 Brazilian (aged 35.6 ± 15.8 years) and 505 Chinese (aged 31.6 ± 10.8 years) eyes with no history of keratoconus or refractive surgery, and 314 Brazilian (aged 24.2 ± 5.7 years) and 74 Chinese (aged 22.0 ± 5.5 years) keratoconic eyes. Orthogonal values of optical flat and steep powers were determined by finding the angular positions of two perpendicular meridians that gave the maximum difference in power. Additionally, the angular positions of the meridians with the minimum and maximum optical powers were located while being unrestricted by the usual orthogonality assumption. Eyes were determined to have non-orthogonal astigmatism if the angle between the two meridians with maximum and minimum optical power deviated by more than 5° from 90°. Evidence of non-orthogonal astigmatism was found in 39% of the Brazilian keratoconic eyes, 26% of the Chinese keratoconic eyes, 29% of the Brazilian normal eyes and 20% of the Chinese normal eyes. The large percentage of participants with non-orthogonal astigmatism in both normal and keratoconic eyes illustrates the need for the common orthogonality assumption to be reviewed when correcting for astigmatism. The prevalence of non-orthogonality should be considered by expanding the prescription system to consider the two power meridians and their independent positions.

Introduction: The nutritional profile of the Brazilian population has changed in recent years. Therefore, this study aimed to assess the prevalence of nutritional status among Brazilian school adolescents during the period from January 2014 to December 2014. Methods: This study employed an observational design with a cohort of school adolescents. Anthropometric measurement was assessed by nutritionists in government schools. The cut-off points for body mass index according to Brazilian criteria for adolescents of both sexes between 10 years and 19 years old were underweight (≤17.5 kg/m2), overweigh (≥25.0 kg/m2), and obesity (≥30.0 kg/m2). Results: The number of students included in the analysis was 2162, of which 71.0% were males and 29% were females (P = 0.00001). The mean age (years) was 13.14 ± 2.17 for boys and 12.66 ± 1.85 for girls (P = 0.0001). The prevalence of underweight, overweight, and obesity observed in our population of school adolescents according to the Brazilian criteria was 2.8%, 8.1%, and 2.4% for males, respectively, and 23.0%, 10.7%, and 3.6% for females, respectively. For both sexes, there was no statistically significant difference between overweight (P = 0.5469) and obesity (P = 0.7863), but there was for underweight (P = 0.001). Conclusions: The occurrence of excess weight among Brazilian school adolescents is similar to the international prevalence, but the prevalence of underweight was very high among girls. The nutritional status of adolescents must be considered a public health problem in Brazil. PMID:27042420

Equine infectious anemia (EIA) has a worldwide distribution, and is widespread in Brazil. The Brazilian Pantanal presents with high prevalence comprising equine performance and indirectly the livestock industry, since the horses are used for cattle management. Although EIA is routinely diagnosed by the agar gel immunodiffusion test (AGID), this serological assay has some limitations, so PCR-based detection methods have the potential to overcome these limitations and act as complementary tests to those currently used. Considering the limited number of equine infectious anemia virus (EIAV) sequences which are available in public databases and the great genome variability, studies of EIAV detection and characterization molecular remain important. In this study we detected EIAV proviral DNA from 23 peripheral blood mononuclear cell (PBMCs) samples of naturally infected horses from Brazilian Pantanal using a semi-nested-PCR (sn-PCR). The serological profile of the animals was also evaluated by AGID and ELISA for gp90 and p26. Furthermore, the EIAV PCR amplified DNA was sequenced and phylogenetically analyzed. Here we describe the first EIAV sequences of the 5' LTR of the tat gene in naturally infected horses from Brazil, which presented with 91% similarity to EIAV reference sequences. The Brazilian EIAV sequences also presented variable nucleotide similarities among themselves, ranging from 93,5% to 100%. Phylogenetic analysis showed that Brazilian EIAV sequences grouped in a separate clade relative to other reference sequences. Thus this molecular detection and characterization may provide information about EIAV circulation in Brazilian territories and improve phylogenetic inferences.

Forensic facial reconstruction: Nasal projection in Brazilian adults.

2016-09-01

The nose has a marked cognitive influence on facial image; however, it loses its shape during cadaveric decomposition. The known methods of estimating nasal projection using Facial Reconstruction are lacking in practicality and reproducibility. We attempted to relate the points Rhinion, Pronasale and Prosthion by studying the angle formed by straight lines that connect them. Two examiners measured this angle with the help of analysis and image-processing software, Image J, directly from cephalometric radiographs. The sample consisted of 300 males, aged between 24 and 77 years, and 300 females, aged 24 to 69 years. The proposed angle ranged from 80° to 100° in both sexes and all ages. It was considered possible to use a 90° angle from projections of the Rhinion and Prosthion points in order to determine the Pronasale position, as well as to estimate the nasal projection of Brazilian adults.

2014-01-01

There is rapidly-emerging evidence on the harmful health effects of sedentary behaviors. The aim of this paper was to quantify time in sedentary behaviors and document socio-demographic variations in different life domains among adults. A population-based survey was carried out in 2012 through face-to-face interviews with Brazilian adults aged 20+ years (N = 2,927). Information about time spent sedentary in a typical weekday was collected for five different domains (workplace, commuting, school/university, watching TV, and computer use at home). Descriptive and bivariate analyses examined variations in overall and domain-specific sedentary time by gender, age, educational attainment and socioeconomic position. On average, participants reported spending 5.8 (SD 4.5) hours per day sitting. The median value was 4.5 (interquartile range: 2.5-8) hours. Men, younger adults, those with higher schooling and from the wealthiest socioeconomic groups had higher overall sedentary scores. TV time was higher in women, older adults and among those with low schooling and socioeconomic position. Sedentary time in transport was higher in men, younger adults, and participants with high schooling and high socioeconomic position. Computer use at home was more frequent among young adults and those from high socioeconomic groups. Sitting at work was higher in those with higher schooling and from the wealthiest socioeconomic groups. Sedentary behavior at school was related inversely to age and directly to schooling. Patterns of sedentary behavior are different by life domains. Initiatives to reduce prolonged sitting among Brazilian adults will be required on multiple levels for different life domains.

International Astronomical Search Collaboration (IASC) is an international educational project between universities, schools, observatories and research institutions. Its main objective is to enroll high school and college students in the monitoring and discovery of asteroids and Near Earth Objects (NEOs), especially Potentially Hazardous Asteroids. The methodology consists in the analysis of astronomical images obtained in several observatories in North America and Hawaii. The images are distributed throughout the school network and the results must be delivered in a 72-hour timeframe. Since 2010 Brazilian universities and schools have joined IASC, resulting in over a dozen new asteroids found (3 of them NEOs), and hundreds of measurements for already known asteroids. A major event in this collaboration was the All-Brazil Asteroid Search Campaign, which was conducted in September 2012. 2013 marks the fourth year of Brazilian participations in IASC, with one important milestone: the third straight appearance of a Brazilian institution in the Pan-STARRS campaign, which uses the PS1 telescope in Haleakala, Hawaii. We will present a summary of the overall results, as well as the latest news from 2013 campaigns. We will discuss the impact promoted by the past events, such as how the interest in astronomy changed before and after the campaigns, and it has helped the students to choose their future careers.

Capsicum peppers are known as a source of capsaicinoids, phenolic compounds and antioxidants. Brazilian Capsicum peppers are important spices used in foods worldwide. However, little information is available on the chemical composition and antioxidant activity of these peppers. Capsaicin, dihydrocapsaicin, total phenolic compounds and antioxidant activity were investigated in extracts of three Brazilian peppers: Capsicum frutescens, C. chinense and C. baccatum var. pendulum, in two different harvest years and at two ripening stages. The bioactive compound content was dependent on harvest year, and changes in the concentration profiles were found for capsaicin. Mature fruits of C. chinense harvested in the first year had the highest capsaicin concentration (2.04 mg g -1 fresh pepper), and mature fruits of C. frutescens harvested in the same first year had the highest dihydrocapsaicin content (0.95 mg g -1 fresh pepper). Mature fruits of C. frutescens harvested in the first year showed the major total phenolic compound content (2.46 mg g -1 fresh pepper). The total phenolic compound content was directly related to antioxidant activity. Our results suggest that phenolic compounds significantly contribute to the antioxidant activity of the investigated peppers. Also, these data add valued novel information that enhances current knowledge of Brazilian pepper fruits. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

The Brazilian Osteoporosis Study (BRAZOS) is the first epidemiological study carried out in a representative sample of Brazilian men and women aged 40 years or older. The prevalence of fragility fractures is about 15.1% in the women and 12.8% in the men. Moreover, advanced age, sedentarism, family history of hip fracture, current smoking, recurrent falls, diabetes mellitus and poor quality of life are the main clinical risk factors associated with fragility fractures. The Brazilian Osteoporosis Study (BRAZOS) is the first epidemiological study carried out in a representative sample of Brazilian men and women aged 40 years or older with the purpose of identifying the prevalence and the main clinical risk factors (CRF) associated with osteoporotic fracture in our population. A total of 2,420 individuals (women, 70%) from 150 different cities in the five geographic regions in Brazil, and all different socio-economical classes were selected to participate in the present survey. Anthropometrical data as well as life habits, fracture history, food intake, physical activity, falls and quality of life were determined by individual quantitative interviews. The representative sampling was based on Brazilian National data provided by the 2000 and 2003 census. Low trauma fracture was defined as that resulting of a fall from standing height or less in individuals 50 years or older at specific skeletal sites: forearm, femur, ribs, vertebra and humerus. Sampling error was 2.2% with 95% confidence intervals. Logistic regression analysis models were designed having the fragility fracture as the dependent variable and all other parameters as the independent variable. Significance level was set as p < 0.05. The average of age, height and weight for men and women were 58.4 +/- 12.8 and 60.1 +/- 13.7 years, 1.67 +/- 0.08 and 1.56 +/- 0.07 m and 73.3 +/- 14.7 and 64.7 +/- 13.7 kg, respectively. About 15.1% of the women and 12.8% of the men reported fragility fractures. In the women, the

2013-01-01

The growth of the Brazilian economy in recent years has created an atmosphere of optimism in various segments of Brazilian society, with several important international repercussions. In this paper, we analyze in detail how this economic growth is reflected in investments in science and technology made by major academic funding agencies. As a result, we observed a discrepancy in the growth of funding input and the growth of the Brazilian gross domestic product. This fact associated with an increased academic output entails negative consequences for the system. This may be a symptom of an academic community not fully understood by society and vice versa. Finally, we believe that a long-lasting important change in investment policy in science is necessary in order to ensure financial security for the academic system as a whole. PMID:23369977

Naming and Shaming for Conservation: Evidence from the Brazilian Amazon

Cisneros, Elías; Zhou, Sophie Lian; Börner, Jan

2015-01-01

Deforestation in the Brazilian Amazon has dropped substantially after a peak of over 27 thousand square kilometers in 2004. Starting in 2008, the Brazilian Ministry of the Environment has regularly published blacklists of critical districts with high annual forest loss. Farms in blacklisted districts face additional administrative hurdles to obtain authorization for clearing forests. In this paper we add to the existing literature on evaluating the Brazilian anti-deforestation policies by specifically quantifying the impact of blacklisting on deforestation. We first use spatial matching techniques using a set of covariates that includes official blacklisting criteria to identify control districts. We then explore the effect of blacklisting on change in deforestation in double difference regressions with panel data covering the period from 2002 to 2012. Multiple robustness checks are conducted including an analysis of potential causal mechanisms behind the success of the blacklist. We find that the blacklist has considerably reduced deforestation in the affected districts even after controlling for the potential mechanism effects of field-based enforcement, environmental registration campaigns, and rural credit.

Osteoporosis is the leading cause of fractures in the population older than 50 years. This silent disease affects primarily postmenopausal women and the elderly, and the morbidity and mortality rates are high. The main goal of treating osteoporosis is the prevention of fractures. The identification of populations at risk through early diagnosis and treatment is essential. The last Brazilian guideline for the treatment of postmenopausal osteoporosis was elaborated in 2002. Since then, new strategies for diagnosis and risk stratification have been developed, and drugs with novel action mechanisms have been added to the therapeutic arsenal. The Osteoporosis and Osteometabolic Diseases Committee of the Brazilian Society of Rheumatology, in conjunction with the Brazilian Medical Association and other Societies, has developed this update of the guidelines for the treatment of postmenopausal osteoporosis according to the best scientific evidence available. This update is intended for professionals in many medical and health specialties involved in the treatment of osteoporosis, for physicians in general and for health-related organizations.

The question of whether Chlamydia trachomatis (Ct) is a cofactor for human Papillomavirus (HPV) in cervical carcinogenesis is still controversial. We conducted a molecular detection study of both infections in 622 Brazilian women, including 252 women with different grades of abnormal cervical cytology and cervical cancer (CC; cases) and 370 women with normal cytology (controls). Although Ct infection did not seem related to CC carcinogenicity, women with abnormal cytology had a significant high rate of Ct infection. Therefore, it is important to adopt protocols for diagnosis and treatment of this bacterium in conjunction with screening for CC in this population. PMID:23128289

Regionalization and political dynamics of Brazilian health federalism.

Dourado, Daniel de Araujo; Elias, Paulo Eduardo Mangeon

2011-02-01

The implications from the Brazilian federal structure on the regionalization of health actions and services in the National Unified Health System (SUS) were analyzed, considering that the regional health planning in Brazil takes place within the context of intergovernmental relations as an expression of cooperative federalism in health. The analysis was based on a historical approach to Brazilian health federalism, recognizing two development periods, decentralization and regionalization. Regional health planning of SUS was explored in light of the theoretical framework of federalism. It is concluded that relative centralization of the process is needed in intergovernmental committees to actualize federal coordination and that it is essential to consider formalizing opportunities for dissent, both in regional management boards and in the intergovernmental committees, so that the consensus decision-making can be accomplished in healthcare regionalization.

Obesity is highly related to negative reproductive health outcomes, but its relationship with spontaneous abortion and stillbirth remains to be understood, especially in transitioning economies. This study aimed to examine the relationship between obesity and spontaneous abortions and stillbirths in a representative sample of the Brazilian population. Cross-sectional study using secondary data of Brazilian women of reproductive age (15-45 years old) from the National Demographic and Health Survey in 2006. Obesity was measured by body mass index (BMI), waist circumference (WC) and waist-to-height ratio (WHR). Logistic regression modeling of the survey data was used to evaluate the relationship between obesity and the study outcomes. The three obesity markers used were found to be strongly and positively associated with spontaneous abortion and stillbirth occurrence. In the adjusted models, there was strong evidence that for each unit increase in BMI (OR = 1.05; 95%CI: 1.02-1.08) and WHR (OR = 1.32; 95%CI: 1.03-1.69), the odds of having a spontaneous abortion was higher. In addition, compared to those of optimal weight, obese women were more likely to have negative outcomes. Maternal age, parity, skin color, educational level and household income were important covariates for adjustment. A sensitivity analysis among women who had only one pregnancy was also performed and showed similar results. Obesity is potentially associated with an increased risk of spontaneous abortion and stillbirth in a representative sample of the Brazilian population. These findings are in accordance with previous studies and thus reinforce the need for obstetric care providers to counsel obese reproductive-age women regarding the risks, complications and importance of weight loss and weight control prior to pregnancy.

Objective To evaluate how the country of origin affects the probability of being delivered by cesarean section when giving birth at public Portuguese hospitals. Study Design Women delivered of a singleton birth (n = 8228), recruited from five public level III maternities (April 2005–August 2006) during the procedure of assembling a birth cohort, were classified according to the country of origin and her migration status as Portuguese (n = 7908), non-Portuguese European (n = 84), African (n = 77) and Brazilian (n = 159). A Poisson model was used to evaluate the association between country of birth and cesarean section that was measured by adjusted prevalence ratio (PR) and respective 95% confidence intervals (95%CI). Results The cesarean section rate varied from 32.1% in non-Portuguese European to 48.4% in Brazilian women (p = 0.008). After adjustment for potential confounders and compared to Portuguese women as a reference, Brazilian women presented significantly higher prevalence of cesarean section (PR = 1.26; 95%CI: 1.08–1.47). The effect was more evident among multiparous women (PR = 1.39; 95%CI: 1.12–1.73) and it was observed when cesarean section was performed either before labor (PR = 1.43; 95%CI: 0.99–2.06) or during labor (PR = 1.30; 95%CI: 1.07–1.58). Conclusions The rate of cesarean section was significantly higher among Brazilian women and it was independent of the presence of any known risk factors or usual clinical indications, suggesting that cultural background influences the mode of delivery overcoming the expected standard of care and outcomes in public health services.

Nowadays, trades and research have become closely related between different countries and anthropometric data are important for the development in global markets. The appropriate use of anthropometry may improve wellbeing, health, comfort and safety especially for footwear design. For children a proper fit of footwear is very important, not constraining foot growth and allowing a normal development. The aim of this study was to compare the anthropometric characteristics of German and Brazilian children's feet from 3 to 10 years of age. We compared five indirect measures of two databases of children's feet. Forefoot, midfoot and rearfoot widths were measured in static footprints and the Chippaux-Smirak and Staheli indices of the longitudinal arch were calculated. Brazilian children showed a significantly narrower forefoot from 5 to 10 years, wider rearfoot from 3 to 4 years, wider midfoot for 4 year-olds and narrower midfoot for 10 year-old children. Nevertheless, the Chippaux-Smirak and Staheli indices showed no group differences. The only exception was for 4 year-old Brazilian children who showed a higher Chippaux-Smirak index compared to German children (48.4 ± 17.7%; 42.1 ± 13.8%). Our study revealed anthropometric differences in absolute forefoot and rearfoot widths of German and Brazilian children, but a similar longitudinal arch development. At 4 years of age, Brazilian children present a foot anthropometry similar to the 3 year-olds and develop the plantar longitudinal arch from 4 to 5 years more rapidly when compared to German children.

The aim of this study was to evaluate the validity and reliability of the Portuguese version of the Weight Concerns Scale (WCS) when applied to Brazilian university students. The scale was completed by 1084 university students from Brazilian public education institutions. A confirmatory factor analysis was conducted. The stability of the model in independent samples was assessed through multigroup analysis, and the invariance was estimated. Convergent, concurrent, divergent, and criterion validities as well as internal consistency were estimated. Results indicated that the one-factor model presented an adequate fit to the sample and values of convergent validity. The concurrent validity with the Body Shape Questionnaire and divergent validity with the Maslach Burnout Inventory for Students were adequate. Internal consistency was adequate, and the factorial structure was invariant in independent subsamples. The results present a simple and short instrument capable of precisely and accurately assessing concerns with weight among Brazilian university students. Copyright © 2015 Elsevier Ltd.

To determine whether the Alberta Infant Motor Scale (AIMS) requires reference values specific for Brazilian infants. A total of 660 (330 girls) healthy full-term infants from Belo Horizonte were assessed using the AIMS. Scores and percentile curves were compared with the Canadian reference values. Differences were found in the 5th percentile (9-<10 and 10-<11 months) and the 10th percentile (4-<5, 9-<10, and 10-<11 months) curves. No significant differences were found between sexes on the basis of the economic classification or the criteria of the Human Development Index. Primarily because of the corrections made to the 5th and 10th percentile curves, we recommend the use of the Brazilian infant data curves reported here for further studies conducted in Brazil. Because the Human Development Index of Belo Horizonte is similar to that for Brazil as a whole, the results of this study should be relevant for clinicians throughout Brazil.

Brazilian green propolis is known as an appreciable natural antioxidant with abundant polyphenolic compounds. For quality control, a fingerprint-efficacy study of Brazilian green propolis was carried out in this work. Chemical fingerprints of Brazilian green propolis from 22 different sources were determined by HPLC and investigated by similarity analysis. The fingerprint-efficacy relationships between chemical fingerprint and DPPH radical-scavenging activity were established. The results showed that 14 characteristic common peaks were identified, and 9 compounds were discovered with free radical-scavenging activities. Caffeoylquinic acids and artepillin C might be the major effective components for quality control of Brazilian green propolis due to their specificity and strong antioxidant activity. This study provides new markers for the quality assessment of Brazilian green propolis and its derived products. © 2017 Institute of Food Technologists®.

The technological obsolescence of the Brazilian eletronic ballot box.

Camargo, Carlos Rogério; Faust, Richard; Merino, Eugênio; Stefani, Clarissa

2012-01-01

The electronic ballot box has played a significant role in the consolidation of Brazilian political process. It has enabled paper ballots extinction as a support for the elector's vote as well as for voting counting processes. It is also widely known that election automation has decisively collaborated to the legitimization of Brazilian democracy, getting rid of doubts about the winning candidates. In 1995, when the project was conceived, it represented a compromise solution, balancing technical efficiency and costs trade-offs. However, this architecture currently limits the ergonomic enhancements to the device operation, transportation, maintenance and storage. Nowadays are available in the market devices of reduced dimensions, based on novel computational architecture, namely tablet computers, which emphasizes usability, autonomy, portability, security and low power consumption. Therefore, the proposal under discussion is the replacement of the current electronic ballot boxes for tablet-based devices to improve the ergonomics aspects of the Brazilian voting process. These devices offer a plethora of integrated features (e.g., capacitive touchscreen, speakers, microphone) that enable highly usable and simple user interfaces, in addition to enhancing the voting process security mechanisms. Finally, their operational systems features allow for the development of highly secure applications, suitable to the requirements of a voting process.

Metalloproteinase 9 (MMP9) is involved in the degradation of extracellular matrix molecules, and its polymorphism rs17576 (Gln279Arg) has been associated with diabetes. We investigated the association of rs17576 in a case-control study with Euro-Brazilian women with gestational diabetes. The study group consisted of a total of 262 Euro-Brazilian pregnant women classified as either healthy (n = 131, control) or with GDM (n = 131). Fluorescent probes with real time PCR (TaqMan system) were applied for genotyping. All groups were in Hardy-Weinberg equilibrium. The minor allele frequencies (G-allele) for rs17567 in healthy and GDM women were 27.1% [95% CI, 22 - 32] and 37.4% [95% CI, 32 - 43], p = 0.011, respectively. Genotypic comparison showed a significant difference (p < 0.05) between the groups. Polymorphism rs17567 was associated with GDM in the studied population and carriers of the G-allele showed an increased risk for gestational diabetes (Odds ratio 1.61; 95% CI, 1.1 - 2.3).

Attribution of CO2 emissions from Brazilian deforestation to domestic and international drivers

NASA Astrophysics Data System (ADS)

Karstensen, J.; Peters, G.

2011-12-01

Efforts to address extensive deforestation to reduce climate change and save primary forests are taking place on a global scale. Whilst several studies have estimated the emissions occurring from deforestation in large rainforests, few studies have investigated the domestic and international drivers sustaining and increasing the deforestation rates. Brazil, having the largest rainforest in the world and one of the highest deforestation rates, is also currently one of the world's largest exporters of soybeans and beef. In this case study we establish the link between Brazilian deforestation and cattle and soybean production, and further attribute emissions to countries and economic sectors through export and import of Brazilian commodities. The emissions from deforestation can therefore be allocated to the countries and sectors consuming goods and services produced on deforested land in Brazil. A land-use change model and deforestation data is coupled with a carbon cycle model to create yearly emission estimates and different emission allocation schemes, depending on emission amortizations and discounting functions for past deforestation. We use an economic multi-regional input-output model (with 112 regions and 57 sectors) to distribute these emissions along agricultural trade routes, through domestic and international consumption in 2004. With our implementation we find that around 80 % of emissions from deforested land is due to cattle grazing, while agricultural transition effects suggests soy beans are responsible for about 20 % of the emissions occurring in 2004. Nearly tree quarters of the soy beans are consumed outside Brazil, of which China, Germany and France are the biggest consumers. Soy beans are consumed by a variety of sectors in the food industry. Brazil exports about 30 % of the cattle it produces, where Russia, USA and Germany are among the largest consumers. Cattle consumption mainly occurs in the meat sectors. In this study we estimate the CO2

This study describes the route followed by nursing in Brazil, through the foundation of nursing organizations and the emergence of nursing leaders and pioneers. To present the origins of modern nursing in Brazil, identifying the main nurse-leaders and analysing their performance for the creation and consolidation of the nursing organizations. It is a historical and social study with descriptive approach, to describe the process of Brazilian nursing professionalization and leadership through a literature review. The oldest nursing organization is the Brazilian Nursing Association that holds scientific and cultural activities. There are also nurses' unions and nursing specialty associations, such as the Brazilian Academy for the History of Nursing, and the Federal Nursing Council. The latter has compulsory membership for controlling nursing services according to the qualifications of the personnel. The very first school for nurses in the Nightingale system was created in São Paulo, 1894, at the Samaritan Hospital, and by the government in 1923, in Rio de Janeiro, for which American nurses, led by Ethel Parsons, sponsored by the Rockefeller Foundation, were essential for the creation of the Anna Nery Nursing School, still in operation within a federal university. Some nurses pioneered these works such as Edith Fraenkel, Maria Rosa Pinheiro, Amalia Carvalho and others. The work done by nursing leaders has brought to the profession a better status and made it more recognized by the society. © 2014 International Council of Nurses.

"Too good to be true": the controversy over the use of permanganate of potash as an antidote to snake poison and the circulation of Brazilian physiology in the nineteenth century.

This article examines an international controversy over the most visible scientific event of Brazilian physiology in the nineteenth century. In 1881, Brazilian scientist João Baptista Lacerda stated that he had found an efficient antidote to the poison of Brazilian snakes: permanganate of potash (nowadays, potassium permanganate). His findings were given great publicity in Brazil and traveled rapidly around the world. Scientists, especially in France, contradicted Lacerda's claims. They argued that permanganate of potash could not be a genuine antidote to snake bites since it could not neutralize snake venom when diffused in the body. Lacerda turned down such criticism, claiming that clinical observation provided solid evidence for the drug's local action, on the spot surrounding the bite. The controversy over the use of permanganate of potash as an antidote to snake bite illustrates different regimes of proof that could be mobilized in favor of a physiological discovery.

The first registers of Somali sheep in Brazil are from the beginning of the 1900s. This breed, adapted to the dry climate and scarce food supply, is restricted in the northeast region of the country. Molecular marker technologies, especially those based on genotyping microsatellite and mtDNA loci, can be used in conjunction with breeding (pedigree analysis) and consequently the maintenance of genetic variation in herds. Animals from the Brazilian Somali Conservation Nuclei from Embrapa Sheep and Goats in Ceará State were used to validate genetic monitoring by traditional pedigree methods and molecular markers. Nineteen microsatellite markers and 404 base pairs from the control region of mtDNA were used. For total herd diversity, an average 5.32 alleles were found, with expected heterozygosity of 0.5896, observed heterozygosity of 0.6451, 0.4126 for molecular coancestrality, and coefficient of inbreeding (F (IS)) was -0.095. Comparing molecular coancestrality means over the years, there was a consistent increase in this parameter within the herd, increasing from 0.4157 to 0.4769 in 2 years (approx. 12% variation). Sixteen mtDNA haplotypes were identified. Inbreeding and other estimates from genealogical analyses confirm the results from molecular markers. From these results, it is possible to state that microsatellites are useful tools in genetic management of herds, especially when routine herd recording is not carried out, or there were gaps in recent generations. As well as pedigree control, genetic diversity can be optimized. Based on the results, and despite herd recording in the herd of Brazilian Somali of Embrapa Sheep and Goats, additional management measures need to be carried out in this herd to reduce inbreeding and optimize genetic variation.

Abstract This study revises centipede fauna found in Brazilian caves, focusing on troglomorphic taxa and emphasizing conservation status. We present 563 centipede specimens from 274 caves across eleven Brazilian states. Of these, 22 records were derived from existing literature and 252 are newly collected. Specimens represent four orders, ten families, 18 genera, and 47 morphospecies. Together, the cave records represent 21 % of Brazil’s centipede fauna. Scolopendromorpha was the most representative order (41 %), followed by Geophilomorpha (26 %), Scutigeromorpha (23 %), and Lithobiomorpha (10 %). Six species were found only in caves, with four considered troglobitic. The distribution of Cryptops iporangensis, the first Brazilian troglobitic centipede species to be discovered, was expanded to other three caves. Cryptops spelaeoraptor and Cryptops iporangensis are two troglobitic species considered Vulnerable and Endangered, respectively, according to the IUCN Red List. Main threats to Brazilian caves are mining, hydroelectric projects, water pollution, and unregulated tourism. PMID:29674871

The Brazilian test is a widely used method for determining the tensile strength of rocks and for calibrating parameters in bonded-particle models (BPMs). In previous studies, the Brazilian disc has typically been trimmed from a compacted rectangular specimen. The present study shows that different tensile strength values are obtained depending on the compressive loading direction. Several measures are proposed to reduce the anisotropy of the disc. The results reveal that the anisotropy of the disc is significantly influenced by the compactibility of the specimen from which it is trimmed. A new method is proposed in which the Brazilian disc is directly generated with a particle boundary, effectively reducing the anisotropy. The stiffness (particle and bond) and strength (bond) of the boundary are set at less than and greater than those of the disc assembly, respectively, which significantly decreases the stress concentration at the boundary contacts and prevents breakage of the boundary particle bonds. This leads to a significant reduction in the anisotropy of the disc and the discreteness of the tensile strength. This method is more suitable for carrying out a realistic Brazilian test for homogeneous rock-like material in the BPM.

To identify the sociodemographic, clinical and self-reported indicators of oral health associated with Brazilian adolescents' satisfaction with oral health. Secondary data were used following the examination of 4,231 adolescents, aged 15 to 19 years, participating in a national oral health survey (SBBrasil 2010). The independent variables were grouped into demographics, predisposition/facilitation, oral health conditions and perceived dental treatment need. Satisfaction with oral health was considered the dependent variable. Ordinal logistic (multiple) regression models tested the variables in sequence (hierarchical), as per the conceptual model, assuming p≤0.05 as the criterion for remaining in the model (Wald test). Adjustment of the model was evaluated with the Akaike information criterion (AIC) and -2 Log L. Participants with perceived treatment need (OR=2.36, 95% CI = 2.14-2.61), toothache (OR=1.18, 1.10-1.28), presence of oral impacts on daily performance (OIDP) (OR= 1.55, 1.44-1.68), severe and very severe dental aesthetic index (DAI) (OR=1.17, 1.08-1.27), were female (OR=1.16, 1.10-1.23), were of black/brown ethnicity (OR=1.10, 1.04-1.17), and had caries in anterior (OR=1.20, 1.08-1.32) and posterior teeth (OR=1.22, 1.13-1.32) presented lower satisfaction with oral health. Satisfaction with oral health in Brazilian adolescents is linked to a multidimensional structure of factors that include demographic aspects, such as gender and ethnic group, self-perception aspects, such as perceived treatment need and oral health impact on daily activities, and clinical aspects, such as the presence of toothache, severe malocclusion and caries in anterior and posterior teeth.

ABSTRACT In the past ten years, there has been an expansion of scientific interest in population genetics linked to both understanding histories of human migration and the way that population difference and diversity may account for and/or be implicated in health and disease. In this article, I examine how particular aspects of a globalizing research agenda related to population differences and genetic ancestry are taken up in locally variant ways in the nascent field of Brazilian cancer genetics. Drawing on a broad range of ethnographic data from clinical and nonclinical contexts in the south of Brazil, I examine the ambiguities that attention to genetic ancestry generates, so revealing the disjunctured and diverse ways a global research agenda increasingly orientated to questions of population difference and genetic ancestry is being used and reused.

The Brazilian Amazon Region is a highly endemic area for hepatitis B virus (HBV). However, little is known regarding the genetic variability of the strains circulating in this geographical region. Here, we describe the first full-length genomes of HBV isolated in the Brazilian Amazon Region; these genomes are also the first complete HBV subgenotype D3 genomes reported for Brazil. The genomes of the five Brazilian isolates were all 3,182 base pairs in length and the isolates were classified as belonging to subgenotype D3, subtypes ayw2 (n = 3) and ayw3 (n = 2). Phylogenetic analysis suggested that the Brazilian sequences are not likely to be closely related to European D3 sequences. Such results will contribute to further epidemiological and evolutionary studies of HBV.

To report a case of Alport's syndrome and to present electronmicroscopic examination findings of the anterior lens capsule of this patient. A 21-year-old man was referred for low visual acuity and retinal pigment epithelial changes in the left eye. The patient and his relatives underwent detailed ophthalmological examination, including electrophysiological testing. The patient also underwent electronmicroscopic examination of the anterior lens capsule. His visual acuity was 6/18 OD and 6/15 OS. Anterior lenticonus and subcapsular opacities were observed in the left eye. Cataract extraction by phacoemulsification with intraocular lens implantation was performed for his poor visual performance. During the capsulorhexis, the remarkably thin and fragile anterior capsule was noted and removed. Ultrastructural analysis of the anterior lens capsule showed a thinner central zone compared with the periphery. The course of Alport's syndrome can be ameliorated by early diagnosis. Therefore, the ophthalmological examination of a patient with anterior lenticonus must be combined with a detailed medical evaluation. Ultrastructural analysis of the lens capsule can support the diagnosis of Alport's syndrome.

Socioeconomic and family influences on dental treatment needs among Brazilian underprivileged schoolchildren participating in a dental health program

PubMed Central

2013-01-01

Background The objective of this study was to compare the socioeconomic and family characteristics of underprivileged schoolchildren with and without curative dental needs participating in a dental health program. Methods A random sample of 1411 of 8-to-10 year-old Brazilian schoolchildren was examined and two sample groups were included in the cross-sectional study: 544 presented curative dental needs and the other 867 schoolchildren were without curative dental needs. The schoolchildren were examined for the presence of caries lesions using the DMFT index and their parents were asked to answer questions about socioenvironmental characteristics of their families. Logistic regression models were adjusted estimating the Odds Ratios (OR), their 95% confidence intervals (CI), and significance levels. Results After adjusting for potential confounders, it was found that families earning more than one Brazilian minimum wage, having fewer than four residents in the house, families living in homes owned by them, and children living with both biological parents were protective factors for the presence of dental caries, and consequently, curative dental needs. Conclusions Socioeconomic status and family structure influences the curative dental needs of children from underprivileged communities. In this sense, dental health programs should plan and implement strategic efforts to reduce inequities in oral health status and access to oral health services of vulnerable schoolchildren and their families.

Animal venoms have been widely investigated throughout the world. The great number of biotechnological articles as well as patent applications in the field of drug discovery based on these compounds indicates how important the source is. This review presents a list of the most studied Brazilian venomous animal species and shows the most recent patent applications filed from 2000 to 2013, which comprise Brazilian venoms, toxins and derivatives. We analyze the data according to the species, the type of products claimed and the nationality of the inventors. Fifty-five patent applications were found, involving 8 genera. Crotalus, Lachesis, Bothrops and Loxosceles represented 78% of the patent applications. The other 22% were represented by Phoneutria, Tityus, Acanthoscurria and Phyllomedusa. Most of the inventions (42%) involved anticancer, immunomodulator or antimicrobial drugs, while 13% involved anti-venoms and vaccines, 11% involved hypotensive compositions, 9% involved antinociceptive and/or anti-inflammatory compositions, and the other 25% involved methods, kits or compositions for various purposes. Brazilian inventors filed 49% of the patent applications, but other countries, mainly the United States of America, Germany, Russia and France, also filed patent applications claiming products comprising venoms, toxins and/or derivatives from the Brazilian fauna. Brazil holds an important number of patent applications which mostly belong to universities and research institutes, but the pharmaceutical industry in this field is still weak in Brazil. Although, Brazilian venomous animal species have been reported in drug discovery throughout the world, many species remain to be explored as valuable and promising tools for drug discovery and development.
