    The short case is a highly artificial scenario, in which the examination candidate is given little or no history and instructed to examine one system or one aspect of a patient and draw conclusions. Despite their artificiality, short cases test clinical skills which senior paediatricians value and consider essential qualities of a competent physician. This article presents some general suggestions on an approach to doing short case examinations.

    Lucio’s phenomenon is an uncommon reaction characterized by severe necrotizing cutaneous lesions that occurs in patients with Lucio’s leprosy and lepromatous leprosy. It is considered by some authors as a variant of type 2 or 3 reaction. Death can occur because of blood dyscrasia or sepsis. Precipitating factors include infections, drugs and pregnancy. We report a 31-year-old female patient exhibiting both clinical and histopathological features of lepromatous leprosy and Lucio’s phenomenon presenting favorable response to treatment. We complement our report with a literature review of the Brazilian cases of Lucio’s phenomenon published in Portuguese and English. PMID:28300896

    We analyze the scores obtained by students who have taken the ENEM examination, The Brazilian High School National Examination which is used in the admission process at Brazilian universities. The average high schools scores from different disciplines are compared through the Pearson correlation coefficient. The results show a very large correlation between the performance in the different school subjects. Even though the students' scores in the ENEM form a Gaussian due to the standardization, we show that the high schools' scores form a bimodal distribution that cannot be used to evaluate and compare students performance over time. We also show that this high schools distribution reflects the correlation between school performance and the economic level (based on the average family income) of the students. The ENEM scores are compared with a Brazilian non standardized exam, the entrance examination from the Universidade Federal do Rio Grande do Sul. The analysis of the performance of the same individuals in both tests shows that the two tests not only select different abilities, but also lead to the admission of different sets of individuals. Our results indicate that standardized tests might be an interesting tool to compare performance of individuals over the years, but not of institutions.

    Purpose The aim of this study was to investigate the use and acceptance of digital radiographic examinations by Brazilian dental practitioners in daily practice and to evaluate the advances that have occurred over the past 5 years. Materials and Methods Dental practitioners enrolled in extension courses at the Piracicaba Dental School, University of Campinas, Brazil, responded to a self-administered questionnaire in the years 2011 and 2015. They were asked about sociodemographic factors and their knowledge and use of digital radiographic examinations. Descriptive analysis was performed, as well as the chi-square and Fisher exact tests, with a significance level of 5% (α=0.05). Results A total of 181 participants responded to the questionnaire in the years 2011 and 2015. Most of the respondents worked in private practice, had graduated within the last 5 years, and were between 20 and 30 years old. In 2011, 55.6% of respondents reported having ever used digital radiographic examinations, while in 2015 this number increased significantly to 85.4% (p<.0001), out of which 71.4% preferred it to conventional images. Moreover, 21.4% of respondents reported having used digital radiographic examinations for more than 3 years. A significant increase in use of intraoral digital radiography (p=0.0316) was observed in 2015. In both years, image quality and high cost were indicated, respectively, as the main advantage and disadvantage of digital radiographic examinations. Conclusion This study showed that digital radiology has become more common in Brazil over the past 5 years. Most of the Brazilian dental practitioners evaluated in 2015 used digital radiographic examinations. PMID:28035301

    2014-09-01

    This paper aims to evaluate the suitability of the Brazilian solid waste policy (BSWP) with global Agenda 21 and the challenges of implementing the BSWP in municipalities. For this, a review of the principles that guided the creation of this policy was performed to demonstrate that international pressures were important in determining its effectiveness. The contradictory relationship between the satisfactory legal framework that established the Brazilian waste management policy and its weakened implementation in the municipalities is also examined . To illustrate the difficulties faced at the local level, a case study involving municipalities that compose the state of Espírito Santowe was undertaken. In this state, the municipalities signed terms of environmental commitment with supervisory agencies who undertook, within a pre-established schedule, to implement a set of actions to shape the proper management of solid waste, adapted to the requirements of national policy and the guidelines of Agenda 21. Finally, the various difficulties in meeting the requirements are discussed. It is necessary and urgent that Brazil finds a way to coordinate the mechanisms of an innovative and well formulated legal instrument to ensure the successful implementation of solid waste management at the local level to achieve the environmental, economic and social objectives.

  9. Explanatory analyses in internal migration: the Brazilian case.

    Abreu, J F

    1980-01-01

    This paper 1) performs an exploratory analysis of internal migration in Brazil, 2) estimates rough migration flows from 1950-1970, and 3) posits hypotheses about internal migration and economic growth. The Brazilian population censuses, which include questions on migration by region, are the main data source for this study. Tobler's gravity model incorporating "wind", or general migration tendencies, is used to show Brazil's internal migration patterns. The basic patterns for 1950 and 1970 are virtually identical. The Cordey-Hayes approach is used to analyze the migration data from an economic point of view. This approach posits a strong positive correlation between directional components of migration and per capita rates. The author hypothesizes that a migration pattern is very much correlated with the stage of development of a country or region. Migration flows are strongly rural to rural in the 1st stage. The 2nd stage shows take-off and the acceleration of development; migrants are drawn to the bright lights of the city at this point. In the 3rd stage, urban predominance leads to a positive correlation between in-migration and out-migration. Migration flows are mostly urban to urban. This theory fits the Brazilian data very well; Brazil's 1960 and 1970 data suggest that it fits into the 2nd stage of take-off and development. These preliminary results effectively delimit the Brazilian migration system.

    The present study conducted a preliminary examination of the psychometric properties of a recently developed Portuguese translation of the Acceptance of Cosmetic Surgery Scale (ACSS; Henderson-King & Henderson-King, 2005). A total of 311 Brazilian adults completed the ACSS along with Portuguese translations of measures of actual-ideal body weight discrepancy, body appreciation, sociocultural attitudes toward appearance, and demographics. Results showed that the Portuguese ACSS reduced to a three-factor solution consisting of the Intrapersonal, Social, and Consider factors uncovered in the original work using the ACSS. Moreover, there were only small sex differences on these subscales. In addition, the Portuguese ACSS showed a good pattern of convergent validity. The availability of the Portuguese ACSS is expected to stimulate more in-depth, quantitative research on attitudes toward cosmetic surgery within the Brazilian context.

    Gorlin-Goltz syndrome (GGS) seems to be unusual in black persons. The authors present an Afro-Brazilian family case report of GGS. The main complaint of the index case was a painless swelling of the left mandible, which was diagnosed as an odontogenic keratocyst. Further classical features of the Syndrome were present in this patient. Other two family members were diagnosed as cases of GGS and one of them presented 11 clinical findings characteristic of the syndrome. From the three cases reported, two of them presented five major diagnostic criteria for the GGS, and the diagnosis was only made because of an oral complaint. This case series emphasizes the importance of carefully examining the patient and close relatives for signs of GGS, even if they belong to an ethnic group in which this diagnosis is unusual.

    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.

    We report four cases of scalp white piedra (SWP) in Brazilian female children. Morphological and physiological approaches gave inconsistent results for identifying Trichosporon to species level, while the sequencing of the intergenic spacer 1 region of ribosomal DNA accurately identified the agent of SWP as T. inkin. These cases emphasize the occurrence of this species causing this type of infection. The molecular identification of the suspected agent is needed for appropriate epidemiological surveillance of superficial mycoses caused by Trichosporon species.

    2011-03-01

    The Kangaroo Program, originally developed in Colombia, was adopted as a public policy by the Brazilian Unified Health System (SUS) in 2000, in an effort to improve maternal and infant health in the country. This article aims to examine the Kangaroo Program as it is practiced and carried out at a maternity hospital in the northeastern Brazilian region. Through an institutional ethnographic approach, research demonstrates that the Kangaroo Program has been effective in saving lives and improving some of the infants' health outcomes. However, research also demonstrates that: (i) the socioeconomic profile of mothers in the Kangaroo Program, (ii) conflicting relationships between healthcare workers and users, and (iii) lack of socioeconomic and emotional support are impairing the adequate implementation of the program. Due to the low literacy level of most of these mothers, institutional power is used as a form of social control to keep mothers uninformed about the possibility of leaving the maternity wards. In a two-tier health system, this controlling behavior is part of existing social inequities, as the Kangaroo Program is a choice in the private health system but tends to be mandatory at SUS maternity hospitals across Brazil.

    Weismann-Netter-Stuhl syndrome was first described in 1954 and is defined by an anterior curvature of the bones of the lower limbs, usually bilateral and symmetrical. Since its initial description, 82 cases were reported, including only 14 pediatric patients. The authors report two cases of this syndrome. One patient was an adult who presented with almost all the characteristic features of the disease. The second case was a 12-year-old girl who also presented with severe bone deformities of the upper limbs. Weismann-Netter-Stuhl syndrome is probably more common than previously reported and must be included in the differential diagnosis of rickets/osteomalacia, congenital syphilis and some cases of Paget's disease.

    Objectives 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. Methods 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. Results 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. Conclusions 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.

    Circumscribed palmoplantar hypokeratosis is a recently recognized dermatosis and rarely reported. It was first described in 2002 and is characterized by localized loss of the horny layer in the palmoplantar area. This dermatosis is clinically presented with a sharply circumscribed, reddish and asymptomatic plaque with slightly depressed surface localized on the palms or the soles. The clinical differential diagnosis includes mainly porokeratosis and Bowen's disease. Its pathogenesis remains unknown, but studies have proposed a human papillomavirus induced disease or a localized keratinization disorder in the palmoplantar area. We report herein two cases of patients with lesions clinically and microscopically compatible with the diagnosis of circumscribed palmoplantar hypokeratosis. We also present a brief literature review of the etiopathogenic hyphoteses of this dermatosis.

    Background Scorpion stings are a major public health problem in Brazil, with an increasing number of registered cases every year. Affecting mostly vulnerable populations, the phenomenon is not well described and is considered a neglected disease. In Brazil, the use of anti-venom formulations is provided free of charge. The associate scorpion sting case is subject to compulsory reporting. This paper describes the epidemiology and identifies factors associated with severity of scorpions stings in the state of Amazonas, in the Western Brazilian Amazon. Methodology/Principal Findings This study included all cases of scorpion stings in the state of Amazonas reported to the Brazilian Diseases Surveillance System from January 1, 2007 to December 31, 2014. A case-control study was conducted to identify factors associated with scorpions sting severity. A total of 2,120 cases were reported during this period. The mean incidence rate in the Amazonas was 7.6 per 100,000 inhabitants/year. Scorpion stings showed a large spatial distribution in the state and represent a potential occupational health problem for rural populations. There was a positive correlation between the absolute number of cases and the altimetric river levels in the Central (p<0.001; Rs = 0.479 linear) and Southwest (p = 0.032; linear Rs = 0.261) regions of the state. Cases were mostly classified as mild (68.6%), followed by moderate (26.8%), and severe (4.6%). The overall lethality rate was 0.3%. Lethality rate among children ≤10 years was 1.3%. Age <10 years [OR = 2.58 (95%CI = 1.47–4.55; p = 0.001)], stings occurring in the rural area [OR = 1.97 (95%CI = 1.18–3.29; p = 0.033) and in the South region of the state [OR = 1.85 (95%CI = 1.17–2.93; p = 0.008)] were independently associated with the risk of developing severity. Conclusions/Significance Scorpion stings show an extensive distribution in the Western Brazilian Amazon threatening especially rural populations, children ≤10 in particular. Thus

    Summary. Background. This report describes the case of a patient with focal epithelial hyperplasia (FEH), a rare but distinctive entity of viral aetiology with characteristic clinical and histopathological features. Case report. The condition is usually seen in children and adolescents of American Indian and Eskimo background. Surgical removal of papillomatous lesions is the treatment of choice, either for aesthetic reasons, or when the lesions interfere with function or are readily traumatized. Recurrence and the site of new lesions are unpredictable, and continued review of the patient is often necessary. The patient described here has been followed for 24 months without recurrences or changes in the aspect of the remaining lesions. Conclusion. This case highlights a possible genetic predilection for FEH, since the patient is a descent of a Brazilian Xavante Indian.

    A techno-economic analysis for use of brewer's spent grains (BSG) on a biorefinery concept for the Brazilian case is presented. Four scenarios based on different levels of heat and mass integration for the production of xylitol, lactic acid, activated carbon and phenolic acids are shown. A simulation procedure using the software Aspen Plus and experimental yields was used. Such procedure served as basis for the techno-economic and environmental assessment according to the Brazilian conditions. Full mass integration on water and full energy integration was the configuration with the best economic and environmental performance. For this case, the obtained economic margin was 62.25%, the potential environmental impact was 0.012 PEI/kg products, and the carbon footprint of the processing stage represented 0.96 kg CO2-e/kg of BSG. This result served as basis to draw recommendations on the technological, economic and environmental feasibility for implementation of such type of biorefinery in Brazil.

    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.

    2016-10-01

    This paper aims at contributing to the UNESCO-IAU Astronomy and World Heritage Initiative's discussions by presenting the case study of a 20th-century observatory located in a South American country. In fact, the National Observatory of Brazil was created in the beginning of the 19th century, but its present facilities were inaugurated in 1921. Through this paper a brief description of the heritage associated with the Brazilian observatory is given, focused on its main historical instruments and the scientific and social roles it performed along its history. By way of conclusion, the paper suggests that the creation of the Museum of Astronomy and Related Sciences with its multidisciplinary team of academic specialists and technicians was decisive for the preservation of that expressive astronomical heritage.

    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.

    Title 9, Chapter 19, Article 3 of the Arizona Administrative Code requires all bodies that are to be cremated must have the death certificate reviewed by a county medical examiner. In Tucson, AZ, and surrounding Pima County, all cremation requests are submitted to the Forensic Science Center, where the death certificates are reviewed by one of 5 board-certified forensic pathologists. In 2002, there were 5557 cremation requests, and in 2003 there were 5662 cremation requests. Of these requests, 670 (12.1%) and 447 (7.9%) death certificates were flagged for further investigation in 2002 and 2003, respectively. Eventually, 47 cases (0.8% of total, 7.0% of flagged cases) were accepted as medical examiner cases in 2002, and 43 cases (0.8% of total, 9.6% of flagged cases) were accepted as medical examiner cases in 2003. In 2002, the majority of cases were handled as a records review; however, 4 cases were brought in for autopsy and 1 was certified after an external examination only. In 2003, all cases were certified via a records review. The manner of death in all but 3 of these deaths was certified as accident, with complications of remote trauma being the most common proximate cause of death. The 3 most common injuries were complications of fractured pelvis or femur (15 in 2002, 22 in 2003), head injury due to fall (18 in 2002, 8 in 2003), and complications of remote motor vehicle accident (3 in 2002, 6 in 2003). The other 3 deaths included 2 homicides, 1 in each year, and 1 suicide in 2003.

    Purpose We performed ophthalmic examinations, including optical coherence tomography (OCT), on a case diagnosed with hydranencephaly. Case Report This case involved a female infant born at the gestational age of 35 weeks and 4 days, with the birth weight of 2,152 g, who was one of monochorionic diamniotic twins, and the identical twin died in utero at the gestational age of 24 weeks. After that, examination by fetal echo indicated that she had microcephaly and ventriculomegaly. Postnatal magnetic resonance imaging (MRI) of her head indicated microcephaly and significant enlargement of the lateral ventricle on both sides, with no obvious signs of elevated intracranial pressure. The brain parenchyma of both sides of the frontal lobe, parietal lobe, and occipital lobe had marked thinning, yet that of the temporal lobe, basal ganglia, thalamus, brain stem, and cerebellum had been maintained. Moreover, no obvious hematoma or neoplastic lesions were observed. Ophthalmic examinations indicated that both of her eyes had slight light reflex, attributed to optic nerve atrophy. Examination by use of a hand-held OCT system indicated a layered structure of the retina and thinning of the ganglion cell layer. Flicker electroretinogram (ERG) examination by use of a hand-held ERG system indicated an almost normal wave. However, no clear visual reaction was observed when she was 10 months old. Conclusion Our findings in this case of hydranencephaly revealed that even though the outer layer functions of the patient's retina were maintained, extensive damage to her cerebral cortex resulted in poor visual function.

    Carcinoma ex pleomorphic adenoma (CXPA) is a rare tumour, with different prevalence rates reported among studies. Epidemiological studies of large series of CXPAs in developing countries are scarce. The aim of the present study was to describe Brazilian patients with CXPA; this was a retrospective study of 38 patients. Demographic and clinico-pathological features were evaluated. No preferential gender was found, and the mean age at diagnosis was 57.6 years. The most commonly involved site was the parotid, followed by the submandibular and the minor salivary glands. A prevalence of clinical stages III and IV was observed at diagnosis. The most common histological subtypes were salivary duct carcinoma, adenocarcinoma not otherwise specified, myoepithelial carcinoma, and epithelial-myoepithelial carcinoma. Moreover, by invasive phase, most were frankly invasive carcinoma. Recurrence was observed in seven out of 24 patients with outcome information available, and all were invasive cases. All seven patients died of causes related to the disease. The distributions of cases according to age, gender, tumour location, and clinical stage were similar to those reported in the literature. Frankly invasive cases presented a worse prognosis. More information is needed to further our understanding of the clinico-pathological aspects of CXPA.

  10. Interpretation of automotive light bulb examination results: an intriguing case.

    2007-01-01

    During the examination of light bulbs from a vehicle involved in a road accident, the headlights did not reveal any evidence regarding whether they were energized or not. Additionally, a police officer turned the lights on after the accident to verify their functioning, thus damaging some of the evidence. By examining the vehicle, it was determined that the park lights could provide answers regarding the conditions of the headlights. After observations, it was concluded that the park lights and headlights were off at the time of the impact. This case report demonstrates how important it is to integrate the circumstances surrounding the case into the interpretation of the results. Nevertheless, it also demonstrates the necessity for examining both the vehicle and all light bulbs in order to reach the most pertinent and proper conclusion.

    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

    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.

    BACKGROUND: Leprosy is millenary disease and still persists in several countries. OBJECTIVES: To estimate the incidence of leprosy in the Brazilian states and for the country in the year 2010; to describe the cases reported according to the studied variables; to verify the correlation between the overall incidence and the studied variables. METHODS: Ecological descriptive study, with population data from the 27 states, 2010. Information about reported cases were collected: gender, race, percentage of patients younger than 15 years old and living conditions. The analysis was performed using percentages, means, incidence rates and the Spearman correlation test. RESULTS: The states of Mato Grosso and Tocantins recorded the highest incidence rates; Rio Grande do Sul and Santa Catarina, the lowest; there was a higher incidence of leprosy among men; the incidence of leprosy increases proportionally with the nonwhites among the inhabitants; patients younger than 15 years; the average number of residents per household; and a decrease in coverage of water supply and presence of bathrooms. CONCLUSION: The incidence of leprosy is related to factors as gender, race and house conditions (p<0,05 for all). PMID:26982775

    2010-05-01

    This article analyzes the practice of infanticide in indigenous communities in Brazil. Taking as a reference point a specific case involving two children of the Zuruahá people, it takes a broader look at the issue and discusses how infanticide is understood among other indigenous peoples. A debate focusing specifically on this topic that took place during a public hearing held in the Brazilian National Congress in December 2005 has also been taken into consideration in this discussion. In view of the positions adopted as a result of the hearing, this paper seeks to identify the ethical problems and moral dilemmas relating to the subject, by putting them into context and analyzing them in the light of respect for cultural pluralism. Seeking to contribute to the debate, the authors analyze the possibilities for intervention in the traditional practices of infanticide, while rejecting those positions that are not anchored in an attitude of profound respect for other people's cultures or that do not create conditions for dialogue between individuals or groups with different moralities.

    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.

    Background Odontogenic tumors (OTs) are rare lesions, exclusive of the jaws, that are derived from epithelial and/or ectomesenchymal elements of the tooth-forming apparatus. Their biological behavior is heterogeneous, including hamartomatous tissue proliferation, benign nonaggressive and aggressive neoplasms, and malignant tumors with metastatic capacity. The aim of this study was to describe the relative frequency of odontogenic tumors in a Brazilian population. In addition, a review of the literature identified studies on odontogenic tumors that follow the 2005 World Health Organization. Material and Methods A total of 376 cases of odontogenic tumors from an oral pathology service were reviewed about age, gender, anatomic site and histologic diagnosis. Results Keratocystic odontogenic tumors (31.6%) were the most common, followed by ameloblastoma (28.5%), and odontoma (22.6%). The mean age was 32.2 years, and more than half the patients (52.1%) were in the second and third decades of life. The male to female ratio was 1:1.37, with a maxilla to mandible ratio of 1:2.08. Conclusions The variation in relative frequency of tumors observed among the several series, including the present study, is probably due in part to cultural differences between geographic areas but also to the study design. Key words:Pathology, epidemiology, odontogenic tumors. PMID:28160576

    Chlorhexidine is widely used as an antiseptic and disinfectant in medical and nonmedical environments. Although the sensitization rate seems to be low, its ubiquitous use raises the possibility of sensitization in many patients and medical care workers. We describe a patient with anaphylaxis during digital rectal examination with chlorhexidine jelly. Urticaria, angioedema, dyspnea, and hypotension developed within a few minutes of the rectal examination. The patient fully recovered after treatment with epinephrine and corticosteroids. Skin tests for chlorhexidine were undertaken 5 weeks later, showing positive prick and intradermal skin tests. Within 30 min of the skin test, the patient complained of febrile sensation, chest tightness, angioedema, and urticaria on the face and trunk. An enzyme allergosorbent test for latex was negative. We present this case to alert clinicians about hypersensitivity to chlorhexidine that could potentially be life-threatening. We suggest that chlorhexidine should be recognized as a causative agent of anaphylaxis during procedural interventions.

    2012-01-01

    This case report sets forth an authenticity examination of 35 encrypted, proprietary-format digital audio files containing recorded telephone conversations between two codefendants in a criminal matter. The codefendant who recorded the conversations did so on a recording system he developed; additionally, he was both a forensic audio authenticity examiner, who had published and presented in the field, and was the head of a professional audio society's writing group for authenticity standards. The authors conducted the examination of the recordings following nine laboratory steps of the peer-reviewed and published 11-step digital audio authenticity protocol. Based considerably on the codefendant's direct involvement with the development of the encrypted audio format, his experience in the field of forensic audio authenticity analysis, and the ease with which the audio files could be accessed, converted, edited in the gap areas, and reconstructed in such a way that the processes were undetected, the authors concluded that the recordings could not be scientifically authenticated through accepted forensic practices.

    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.

    Objectives To explore issues of intervention tailoring for ethnic minorities based on information and experiences shared by researchers affiliated with the Health Maintenance Consortium (HMC). Methods A qualitative case study methodology was used with the administration of a survey (n=17 principal investigators) and follow-up telephone interviews. Descriptive and content analyses were conducted, and a synthesis of the findings was developed. Results: A majority of the HMC projects used individual tailoring strategies regardless of the ethnic background of participants. Follow-up interview findings indicated that key considerations in the process of intervention tailoring for minorities included formative research; individually oriented adaptations; and intervention components that were congruent with participants’ demographics, cultural norms, and social context. Conclusions Future research should examine the extent to which culturally tailoring long-term maintenance interventions for ethnic minorities is efficacious and should be pursued as an effective methodology to reduce health disparities.

  4. Examining an ethical dilemma: a case study in clinical practice.

    2004-01-01

    When clients and health care providers differ in their understanding of what is right or wrong, an ethical dilemma may arise. Such dilemmas occur in everyday clinical practice. Health care providers have the professional responsibility to analyze these dilemmas. A clinical case study of an ethical dilemma that occurred in a cross-cultural context is examined. The language of the client and provider differed, and no interpreter service was available. Given these conditions, the provider's ethical dilemma was whether, and if so how, to give safe, satisfying care that respected the needs of a client with limited English proficiency. Measuring the morality of the provider's decisions and actions using Rawls' ethical theory of social justice finds deficits. A 10-step Bioethical Decision-Making Model by Thompson is used to demonstrate one method for analyzing the moral dimension of a clinical scenario focusing on the decisions and actions taken by a midwife. Scrutinizing ethically challenging clinical encounters will result in better understanding of the moral dimensions of practice.

    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.

    The comparatively high salaries made in Japan are attractive to many Japanese-Brazilians. The number of individuals from this ethnic group being treated in Japanese mental hospitals has increased. We hypothesized that Japanese-Brazilian patients with panic disorders adjusted better to Japanese society and culture than those with other mental disorders. The subjects in the present study are 40 Japanese-Brazilian patients undergoing treatment at the Department of Psychiatry at Jichi Medical School, Japan, from May 1990 to September 1998. Patients were divided into a panic disorder group, a schizophrenic group, a mood disorder group and a neurosis group. Demographic data (Japanese language ability, duration of residence in Japan etc.) were collected. A comparison was made among the four groups. Patients in the panic disorder group showed a significant tendency to be fluent speakers of Japanese. Patients in the panic disorder group also had been in Japan for a significantly longer period of time than those in the other three groups. Japanese ability and length of residence in Japan rule out exacerbating factors due to a foreign living environment. Panic disorder patients usually have resolved the problems inherent in living and working in a foreign country. In general, Japanese-Brazilians are more comfortable both financially and socially in Japan than other foreign laborers because of their cultural and family background. The emotional conflict experienced by such patients may result from concern over whether to live in Brazil or Japan in the future. Their ethnic and cultural identity may be confused, fluctuating between identifying with Brazil and with Japan, and this may cause vague feelings of anxiety.

    Recent efforts to reduce malaria incidence have had some successes. Nevertheless, malaria persists as a significant public health problem in the Brazilian Amazon. The objective of this study was to describe changes in malaria case characteristics and to identify trends in malaria incidence in the Brazilian Amazon. This study used data from the Malaria Epidemiological Surveillance and Case Notification Information System from 2004 to 2013. The annual parasite incidence (API) was calculated and joinpoint regression was used to assess the trends in API over time. There was a sharp increase in API in the state of Acre, followed by two periods of decrease. Pará also presented inconsistent decreases over the study period. Amapá, Amazonas, Rondônia, and Roraima showed statistically significant decreases over the period. The sharpest decrease occurred in Rondônia, with a reduction of 21.7% in the average annual percent change (AAPC) (AAPC: -21.7%; 95% confidence interval: -25.4%, -17.8%; p < 0.05). This panorama of malaria incidence highlights the importance of integrating evidence-based malaria surveillance and control. Malaria is highly preventable, and eliminating its transmission should be a goal in coming decades. PMID:27925018

    During a 12-month period (November 1994-October 1995), Afro-Brazilian Umbanda healers (Pais-de-Santo) taught 126 fellow healers from 51 Umbanda centres (terreiros) located in seven overcrowded slums (favelas) (population 104-343) in Brazil's northeast, the biomedical prevention of AIDS, including safe sex practices, avoidance of ritual blood behaviours and sterilization of cutting instruments. A face-to-face educational intervention by healers, marginalized in society yet respected by devotees, which blended traditional healing-its language, codes, symbols and images- and scientific medicine and addressed social injustices and discrimination was utilized in this project supported by the Brazilian Ministry of Health, National Program in STDs/AIDS. Significant increases (P < 0.001) in AIDS awareness, knowledge about risky HIV behaviour, information about correct condom use, and acceptance of lower-risk, alternative ritual blood practices and decreases (P < 0.001) in prejudicial attitudes related to HIV transmission were found among mobilized healers as compared to 100 untrained controls. Respected Afro-Brazilian Pais-de-Santo can be creative and effective partners in national HIV prevention programmes when they are equipped with biomedical information about AIDS.

    José Pinto de Azeredo, of Rio de Janeiro, studied medicine and conducted notable experimental research in Edinburgh (1786-88), presenting his graduate thesis on gout in Leiden. Already appointed surgeon-general of Angola, he returned to Rio in 1789 and practiced medicine in Brazil. In 1790 he moved to Luanda, where he practiced at the Hospital Real and founded a medical school that did not survive his departure for Portugal in 1797. He worked at Lisbon's main military hospital and as a private physician until his death. His written works (some ten manuscripts and five publications) warrant an examination from the perspective of the history of medicine. In an article published in 1790 on Rio de Janeiro's air quality, he reveals the skills of an analytical chemist, his interest in the effects of different air components on organisms, and his concern with air quality in Brazil and Europe.

    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.

    2014-01-01

    Introduction Giant cystadenocarcinomas of the ovary are rarely described conditions. Case presentation The authors describe a 57-year-old Brazilian woman who presented with an increase in abdominal girth in February 2003. Imaging studies showed a giant abdominal pelvic mass with probable origin in the right ovary. Cancer antigen-125 was elevated, while carcinoembrionic antigen and alpha-fetoprotein were normal. Total abdominal hysterectomy, bilateral salpingoophorectomy and omentectomy were done. The mass weighed 40Kg, and the histopathology study revealed a mucinous cystadenocarcinoma. She underwent chemotherapy with paclitaxel and cisplatin with no side effects. Under follow-up for more than 10 years, she is asymptomatic and with normal imaging and laboratory parameters, including the cancer antigen-125 marker. Conclusion This huge tumor evolved for a long time unsuspected and without metastases in a patient from a developing region. The diagnostic and management challenges posed by this unexpected and unusual presentation of an ovarian cystadenocarcinoma are discussed. PMID:24594205

    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

    A lethal case of Brazilian spotted fever (BSF) is presented. Clinical features were initially of gastrointestinal involvement and evolved with progression to septic shock, meningoencephalitis and death on the 6th day of illness. Indirect immunofluorescence assay (IFA) for spotted fever group rickettsia (SFGR) was non-reactive. Diagnosis was confirmed by the polymerase chain reaction (PCR) and the nucleotide sequencing of a fragment of the ompA gene showed 100% homology to Rickettsia rickettsii. BSF has not been reported in the city of Rio de Janeiro in the last three decades, and the present description should alert the clinicians to its presence in urban Rio de Janeiro, and to the differential diagnosis with dengue fever, gastroenteritis, leptospirosis and bacterial septic shock, among others.

    This article applies a gender perspective to the history of social reform efforts in mid-19th century Bombay to help illuminate the origins of Indian modernism. In the Maharaj Libel Case, two social reformers successfully defended a libel suit after they published charges of sexual misconduct against the religious priests of the Pushtimarga Vaishnava sect. The paper contextualizes the discussion with a brief review of the rise of British education in Bombay, a note that the social reformers considered the ideal woman to be a domestic helpmate, and a sketch of the history of the devotional religious sect that worships Krishna. The libel case attracted immense public attention, and the reformers based their defense on charges that the Maharajs (priests) were immoral and exploited female devotees sexually. The priests were described as ignorant and blind while the women were considered merely passive objects subordinate to males. No woman was called to give evidence, but evidence shows that the women willingly visited the priests for sexual acts. The reformers' solution to the problem was for the women they regarded as infantilized and/or degraded to be more firmly controlled by their male kin. The conclusion that the reformers were patriarchal and not concerned about the well-being of women is supported by three cases. The reformers ignored the two in which women brought charges against priests and only urged action in the case of a rape/murder by a priest.

    As students engage in pre-service teacher (PT) activities, they take a number of courses that help prepare them to teach in schools. During that time, they must also form their own understanding of what teaching and learning means for them (Kroll, 2004). In many cases, this can conflict with their view of teaching as a command approach to…

    Malaria in pregnancy is associated with increased risks of maternal anemia, spontaneous abortion, low birth weight, premature delivery and other adverse effects on health. In Brazil, disease transmission is highly concentrated in the multi-state region that constitutes the Brazilian Amazon (more than 99% of all cases). This study, conducted between the first bimesters of 2007 and 2008, aims to identify the local barriers to prompt and effective case management of malaria in pregnancy and was carried out in health facilities located in three endemic municipalities of the Brazilian Amazon (Manaus, Presidente Figueiredo and Porto Velho). The study design combined both qualitative and quantitative descriptive methods. The qualitative design involved semi-structured interviews with health personnel who routinely deal with malaria care. The quantitative design involved a review of medical records of pregnant women in the visited health facilities. Additionally, data were abstracted from SIVEP-Malaria Epidemiological Surveillance Information System (Brasil, 2007) and Primary Care Information System (SIAB) databases. Flaws were detected in diagnosis (only 6.8% of women tested for malaria) and treatment (for Plasmodium falciparum infections, only 44.8% of patients received recommended first-line therapy; 10.2% of prescription presented treatments were not found in national guideline and 7.3% of the prescriptions for Plasmodium vivax and 17.9% of the prescriptions for P. falciparum were not sanctioned by the official guidelines). Training (only 37.3% had had some training), knowledge and counseling were also sub-optimal. These results indicated the need to improve the health-worker performance through training. Close supervision and feedback on the health-worker performance are also needed. These findings also highlighted the need to put into practice a series of government recommendations that encourage close collaboration between the National Malaria Control Program and

    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 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.

    The indications for mandibular anterior ceramic veneers, tooth preparation design, provisionalization considerations, and placement procedures were presented in a previous article by the author. The functional utility, tissue biocompatibility, and dissimilarities of mandibular veneers, in comparison to maxillary anterior ceramic veneers, were explored, along with indications and contraindications for this form of treatment. This article demonstrates the aesthetic range of these restorations in the context of more complex cases. The learning objective of this article is to illustrate the viability of mandibular ceramic veneers in realigning teeth nonorthodontically, while sustaining the biologic health of the periodontium, stability of the occlusion, and aesthetic parameters of each case. The importance of wax mock-ups is outlined for visualization of the final result, as well as the evaluation of root proximity to avoid subgingival ledging of the teeth and subsequent periodontal disease. Orthodontics and other methods for the correction of anterior crowding are discussed.

    Ethernet is the next big thing in the telecom industry. In the metro network, access capacity is always an issue - not enough bandwidth to offer broadband services which will generate new revenue for service providers. Ethernet has been identified as one of the technologies that can break this spell in the next few years. Then why have we not seen large scale metro Ethernet deployment from any carriers? This article examines the issues in optical Ethernet technology, and the strengths and weakness of works in progress trying to solve them.

    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

    This article presents a patient with a long history of type 1 diabetes mellitus complicated with neuropathy and Charcot disease. The most common cause of neuropathic osteoarthropathy, called Charcot osteoarthropathy, is poorly controlled diabetes. The clinical picture is characterized by considerable edema, redness and increased skin temperature with relatively slight pain due to injury to nerve fibers responsible for pain sensation. The differential diagnosis should include bacterial or autoimmune arthritis, arthritis associated with gout as well as venous thrombosis and injury. The contribution of a local inflammatory reaction and abnormal bone turnover with excessive osteoclast activity might play a role in the etiopathogenesis of this disease. As a result, osseous and articular destruction progresses rapidly leading to irreversible deformity of the foot. Avoiding weight-bearing and resting the foot in a specially selected plaster cast is the most important part of treatment. Patients with the aforementioned complaints are referred to radiologists for imaging examinations. An ultrasonographer should pay attention to changes typical of Charcot arthropathy, such as: inflammatory and destructive changes in joints of the foot, uneven contour of bones with thickening and periosteal hyperemia as well as soft tissue swelling.

    Large-scale educational assessment has been established as source of descriptive, evaluative and interpretative information that influence educational policies worldwide throughout the last third of the twentieth century. In the 1990s the Brazilian Ministry of Education developed the National Basic Education Assessment System (SAEB) that regularly measures management, resource and contextual school features and academic achievement in public and private institutions. In 2005, after significant piloting and review of the SAEB, a new sampling strategy was taken and Prova Brasil became the new instrument used by the Ministry to assess skills in Portuguese (reading comprehension) and Mathematics (problem solving), as well as collecting contextual information concerning the school, principal, teacher, and the students. This study aims to identify which variables are predictors of academic achievement of fifth grade students on Prova Brasil. Across a large sample of students, multilevel models tested a large number of variables relevant to student achievement. This approach uncovered critical variables not commonly seen as significant in light of other achievement determinants, including student habits, teacher ethnicity, and school technological resources. As such, this approach demonstrates the value of MLM to appropriately nuanced educational policies that reflect critical influences on student achievement. Its implications for wider application for psychology studies that may have relevant impacts for policy are also discussed. PMID:27933004

    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.

    Focal epithelial hyperplasia (FEH), or Heck's disease, is a rare disease of the oral mucosa associated with infection by some subtypes of human papilloma virus, especially subtypes 13 or 32. The disease is predominantly found in children and adolescents with indigenous heritage, but other ethnic groups can be affected worldwide. To the best of the authors' knowledge, it has not been reported in Brazil's elderly population. This article describes a case of FEH in a 57-year-old Brazilian patient presenting since childhood, with multiple lesions in the lips, buccal mucosa and tongue. The solitary tongue lesion underwent excisional biopsy and the histopathological analysis showed parakeratosis, acanthosis, rete pegs with a club-shaped appearance, koilocytosis and the presence of mitosoid cells. These microscopic findings in conjunction with clinical presentation were sufficient to establish the accurate diagnosis of FEH. Polymerase chain reaction (PCR) was performed, but no one human papillomavirus (HPV) subtype could be identified. Clinicians must be aware of this rare oral disease, which can even affect elderly patients, as we described here. Treatment may be indicated in selected cases due to esthetic and/or functional problems.

    Case-control studies evaluating the factors associated with childhood obesity are scarce in Brazil. We aimed to analyze the factors associated with obesity in Brazilian schoolchildren enrolled in the School Health Program.A case-control study was conducted on 80 schoolchildren aged 7 to 9 years, 40 of them obese and 40 of normal weight according to the cut-off points established by the World Health Organization (2007). Weight, height and waist circumference were obtained. Socioeconomic, demographic, health, eating behavior and lifestyle data were collected by applying a questionnaire to the person responsible and by determining his/her nutritional status. A binary unconditional logistic regression model (univariate and multivariate) was used for data analysis. The prevalence of obesity was 7.21%. The final model showed that duration of breast-feeding ≥ 6 months of age (OR 5.3; 95% CI: 1.3-22.1), excess weight of the person responsible (OR 7.1; 95% CI: 1.2-40.2), a sedentary level of physical activity (OR 4.1; 95% CI: 1.1- 15.5), and fast chewing (OR 7.4; 95% CI: 2.1-26.9) were significantly associated with childhood obesity. The factors associated with obesity in schoolchildren were duration of breast-feeding ≥ 6 months, persons responsible with excess weight, and sedentary children who chew fast. The present study contributes information to be used for the health actions planned by the School Health Program.

    OBJECTIVE: Due to their toxicity, diesel emissions have been submitted to progressively more restrictive regulations in developed countries. However, in Brazil, the implementation of the Cleaner Diesel Technologies policy (Euro IV standards for vehicles produced in 2009 and low-sulfur diesel with 50 ppm of sulfur) was postponed until 2012 without a comprehensive analysis of the effect of this delay on public health parameters. We aimed to evaluate the impact of the delay in implementing the Cleaner Diesel Technologies policy on health indicators and monetary health costs in Brazil. METHODS: The primary estimator of exposure to air pollution was the concentration of ambient fine particulate matter (particles with aerodynamic diameters <2.5 µm, [PM2.5]). This parameter was measured daily in six Brazilian metropolitan areas during 2007-2008. We calculated 1) the projected reduction in the PM2.5 that would have been achieved if the Euro IV standards had been implemented in 2009 and 2) the expected reduction after implementation in 2012. The difference between these two time curves was transformed into health outcomes using previous dose-response curves. The economic valuation was performed based on the DALY (disability-adjusted life years) method. RESULTS: The delay in implementing the Cleaner Diesel Technologies policy will result in an estimated excess of 13,984 deaths up to 2040. Health expenditures are projected to be increased by nearly US$ 11.5 billion for the same period. CONCLUSIONS: The present results indicate that a significant health burden will occur because of the postponement in implementing the Cleaner Diesel Technologies policy. These results also reinforce the concept that health effects must be considered when revising fuel and emission policies. PMID:22760904

    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.

    Despite bans on certain pesticides and their replacement by others considered less hazardous, the widespread use of these substances in agriculture continues to threaten the environment and the health of millions of people. This article discusses the current double standard in the international trade of pesticides and focuses on Brazil, one of the main users of pesticides in the world, analyzing the trends in foreign trade (imports and exports) of selected pesticides as a function of changes in legislation in the United States, the European Union, and Brazil from 1989 to 2006. We applied time line analysis to eight organochlorines already banned in Brazil and conducted a case-by-case qualitative and quantitative analysis of nine other pesticides. The results indicate the existence of double standards, as demonstrated by the continued exports to Brazil of some pesticides banned in the United States and Europe.

    Salivary gland tumors consist of a group of heterogeneous lesions with complex clinicopathological characteristics and distinct biological behaviors. Worldwide series show a contrast in the relative incidence of salivary gland tumors, with some discrepancies in clinicopathological data. The main aim of this study was to describe demographic characteristics of 599 cases in a population from Central Brazil over a 10-year period and compare these with other epidemiological studies. Benign tumors represented 78.3% of the cases. Women were the most affected (61%) and the male:female ratio was 1:1.6. Parotid gland tumors were the most frequent (68.5% of cases) and patient age ranged from 1 to 88 years-old (median of 45 years old). The most frequent tumors were pleomorphic adenomas (68.4%) and benign tumors were significantly more frequent in the parotid (75.9%), while malignant tumors were more frequent in the minor salivary glands (40%) (P < 0.05). In conclusion, women and the parotid gland were the most affected and pleomorphic adenoma was the most frequent lesion, followed by adenoid cystic carcinoma and Warthin’s tumor. PMID:20596844

    Objective To analyze cases of violence against transvestites and transsexuals based on their sociodemographic profile. Method Cross-sectional, descriptive research performed in Cajazeiras / Paraíba, consisting of 16 transvestites and transsexuals. Data collection took place in April 2014 and was analyzed descriptively. Results The typology of violence that victimized transvestites and transsexuals were: verbal (91.96%), psychological (58.33%) and physical (33.33%), often between 24 hours and six months preceding the survey. Regarding the spatiality: the street, school and health services were all scenarios of aggression. With respect to the offending agent, the findings point towards neighbors, family members and health professionals. All forms of violence happened between agents and spaces of aggression. Conclusions Violence among this population, silence around the situations of abuse became more pronounced as did its invisibility in the social and institutional context, reflecting the inhibition of human rights and concealment of reality.

    Contact with Lonomia caterpillars can cause a hemorrhagic syndrome. In Brazil, Lonomia obliqua and Lonomia achelous are known to cause this venom-induced disease. In the Brazilian Amazon, descriptions of this kind of envenomation are scarce. Herein, we report a severe hemorrhagic syndrome caused by Lonomia envenomation in the Amazonas state, Western Brazilian Amazon. The patient showed signs of hemorrhage lasting 8 days and required Lonomia antivenom administration, which resulted in resolution of hemorrhagic syndrome. Thus, availability of Lonomia antivenom as well as early antivenom therapy administration should be addressed across remote areas in the Amazon.

    2011-09-01

    Community forestry initiatives have been shown to reduce rural poverty while promoting the conservation and sustainable use of forests. However, a number of challenges face communities wanting to initiate or maintain formal, community-based forest management. Through a grounded theory approach, this paper uses three case studies of community forest management models in the eastern Amazon to create a framework showing challenges faced by communities at different phases of formal management. The framework shows that, in the development phase, four root problems (land ownership, knowledge acquisition, community organization, and adequate capital) need to be addressed to obtain legal management permission. With this permission in hand, further challenges to operationalization are presented (deterring illegal loggers, maintaining infrastructure, obtaining necessary managerial skills and accessing markets). The interrelatedness of these challenges emphasizes that all challenges need to be addressed in a holistic manner for communities to maintain a profitable and self-sufficient operation. This contradicts current development approaches that only address part of this framework. The framework proposed here can be used as a starting point for community forestry initiatives in other regions.

    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.

    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.

    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.

  10. Micronucleus frequency in children exposed to biomass burning in the Brazilian Legal Amazon region: a control case study

    PubMed Central

    2012-01-01

    Background The Amazon represents an area of 61% of Brazilian territory and is undergoing major changes resulting from disorderly economic development, especially the advance of agribusiness. Composition of the atmosphere is controlled by several natural and anthropogenic processes, and emission from biomass burning is one with the major impact on human health. The aim of this study was to evaluate genotoxic potential of air pollutants generated by biomass burning through micronucleus assay in exfoliated buccal cells of schoolchildren in the Brazilian Amazon region. Methods The study was conducted during the dry seasons in two regions of the Brazilian Amazon. The assay was carried out on buccal epithelial cells of 574 schoolchildren between 6-16 years old. Results The results show a significant difference between micronucleus frequencies in children exposed to biomass burning compared to those in a control area. Conclusions The present study demonstrated that in situ biomonitoring using a sensitive and low cost assay (buccal micronucleus assay) may be an important tool for monitoring air quality in remote regions. It is difficult to attribute the increase in micronuclei frequency observed in our study to any specific toxic element integrated in the particulate matters. However, the contribution of the present study lies in the evidence that increased exposure to fine particulate matter generates an increased micronuclei frequency in oral epithelial cells of schoolchildren.

    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.

    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.

    This work examines the perception by cold case homicide covictims that police have given up trying to solve their loved one's murder. A random sample (n = 65) of cold case homicide covictims is surveyed to determine if, and how, different forms of communication may be important in their perceptions about police. Ordered logistic regression analyses indicate that perceived importance of the information communicated, frequency of police contact, and satisfaction with communication efforts by police are inversely correlated with covictims' perceptions that police have given up on the investigation. These inverse correlations persist despite statistical controls and have important implications for the bereavement of covictims and for crime rates.

    2005-03-10

    The examination of damage to a paper towel, an item of evidence in a murder case, is described. Simulations performed with selected tools and the observation of the lacerations present on the towel permitted to infer that they were originated by cleaning of a pointed and sharp implement. Some marks, considered characteristic of scissors, were detected on the exhibit. This experimental outcome resulted critical in challenging the declarations of the suspect. A rather significant analogy between damage examination on paper towels and on textiles was established.

    Brazil counts as a gemmological province because of the variety of gem minerals present in the country. Most Brazilian states and territories produce gemstones, the State of Minas Gerais being the most important producer both in volume and in number of species. Diamonds are chiefly derived by panning from alluvial deposits in Minas Gerais, Mato Grosso and Goiás. Among other gemstones, the most important are aquamarines, beryls, chrysoberyls, topazes, amethysts, tourmalines, emeralds and agates, and their respective varieties. The occurrences of these gemstones, as well as of a great number of others, are described for each state in which they are found.

    The Brief Coping Orientation to Problems Experienced (COPE) inventory investigates the different ways in which people respond to stressful situations. Knowledge is lacking regarding the coping strategies and styles of people in developing countries, including Brazil. This study aimed to adapt and validate the Brief COPE to Brazilian Portuguese (named COPE Breve) by focusing on dispositional coping. For the cross-cultural adaptation, the original Brief COPE in English (28 items grouped into 14 subscales) was adapted according to a universalistic approach, following these steps: translation, synthesis, back-translation, analysis by an expert panel, and pretest with 30 participants. Then, 237 adults from the community health service responded to the COPE Breve. Psychometric analyses included reliability and exploratory factor analysis. Most of the 14 subscales from the original Brief COPE exhibited problems related to internal consistency. A Velicer's minimum average partial test (MAP) was performed and pointed out 3 factors. Exploratory factor analysis produced a revised 20-item version with a 3-factor solution: religion and positive reframing, distraction and external support. The psychometric properties of the COPE Breve with three factors were appropriate. Limitations of this study as well as suggestions for future studies are presented. The COPE Breve should be used in Brazilian clinics and investigations, but divergences in its psychometrics should be further explored in other contexts.

  1. On matters of causation in personal injury cases: Considerations in forensic examination

    Rheumatologists are often called to be independent examiners of injured claimants and to address the question: “What is causing the injured person’s symptoms?” This article deals with the legal principles that arise in these cases, including causation, convenient focus, secondary gain, and thin skull rules. We shall first set out two hypothetical scenarios of personal injury cases that set the scene for a discussion of legal principles in personal injury law. With the same two scenarios of personal injury in mind, we shall review the legal principles and the biopsychosocial models of the illnesses concerned and consider the importance of examiners going beyond diagnostic labels towards a more in-depth analysis of illness factors and mechanisms that in turn assist the trier of facts.

    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.

    2008-01-01

    For several years now, with the introduction of the health care sector reform we have been observing a considerable drop in the number of postmortem examinations performed in patients who died in hospitals. The decrease amounts to as much as 50 to 70%. This is undoubtedly a consequence of financial restrictions imposed on the management of these inpatient facilities. On the other hand, Departments of Forensic Medicine established to evaluate the so-called medical errors are swamped with an increasing avalanche of complaints concerning the appropriateness of therapeutic management. This leads to a growing number of orders from penal prosecution and jurisdiction agencies with requests for assessment whether a medical error has been committed in a particular case. The result of a postmortem examination is practically the only basis for a factual evaluation of a given case. When no autopsy has been performed, the experts are virtually helpless, and in the majority of such instances, they are forced to refuse passing an expert opinion. The report presents basic principles of medico-legal opinionating in criminal cases (including proceedings pertaining to medical errors), the rules governing the medical error assessment, as well as problems encountered in evaluating the appropriate course of treatment when a post mortem examination has been waived.

    The role of direct virus infection as a determining factor in acquired immunodeficiency syndrome (AIDS) dementia was investigated using in situ hybridisation for human immunodeficiency virus (HIV) and human cytomegalovirus (HCMV). Four of the five AIDS dementia patients in this series demonstrated HIV infected cells distributed in widely different parts of the brain, but only one case showed HCMV infected cells. The greater abundance of HIV was in subcortical white matter in nodular areas consisting of monocyte/macrophage infiltrates. The cells were occasionally arranged as a multinucleated syncitium. In two cases, a few large cells with the appearance of neurons were positive for HIV hybridisation. By appropriate treatment with ribonuclease, it was shown that hybridisation was primarily to HIV RNA. HCMV infected cells were observed in small numbers in only one of the positive cases, suggesting that HCMV is not a determining factor in AIDS dementia. HCMV positive cells were located in the grey matter, with an appearance suggestive of neurons. Cells expressing the MHC-class II antigen HLA-DR, a marker of reactive microglia and macrophages, were observed to be extensive in affected brain sections in the one case examined. These cells were present in greater number than HIV infected cells. In this case, extensive numbers of HIV infected cells were noticed along the peripheral margin of the substantia innominata. This could indicate infection in this case of a critical brain region from the cerebrospinal fluid. Images PMID:2543795

    2011-05-01

    Psychodynamic psychotherapy is effective for a variety of mental health symptoms. This form of psychotherapy uses patient self reflection and self examination, as well as the therapeutic relationship between the patient and psychiatrist, to explore maladaptive coping strategies and relationship patterns of the patient. A thorough understanding of resistance and the core conflictual relationship theme afford the psychiatrist the ability to facilitate this work. In this article, the composite case illustrates some of the psychodynamic psychotherapy techniques that can be employed in a psychotherapy case. In this example, the case is about a certified public accountant that came to treatment because of an acute stressor that put her career goals at risk. An acute episode or event can bring to light chronic and ongoing symptoms, which have had a remitting and relapsing course, and leave the patient unable to compensate on his or her own.

    2016-02-01

    Combined movement examination (CME) of the lumbar spine has been recommended for clinical examination as it confers information about mechanical pain patterns. However, little quantitative study has been undertaken to validate its use in manual therapy practice. This study used computer aided CME to develop a normal reference range, and to guide provisional diagnosis and management. Two cases were assessed, before and after manual therapy using CME, a pain Visual Analogue Scale, the Roland Morris Low Back Pain and Disability Questionnaire and the Short Form (SF-12) Health Survey. Diagnosis and management were guided by comparing each CME pattern with the age and gender matched reference range. Self-reports data and CME total change scores were markedly improved for both cases, particularly for the most painful and restricted CME directions. This report describes how computer-aided CME and a normal reference range may be used objectively to inform a diagnosis and as an outcome measure in cases of mechanical LBP. Future investigations of cases with specific lumbar pathologies are required to validate this concept.

    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 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.

  9. A Case Controlled Examination of the Interpersonal Theory of Suicide in the Second Half of Life.

    2016-07-02

    The interpersonal theory of suicide proposes that the most proximal cause of suicide is the combination of thwarted belongingness and perceived burdensomeness coupled with a pre-existing vulnerability of reduced fear of death and increased pain tolerance. This pre-existing vulnerability develops in response to painful and provocative life events. According to the theory, empirically demonstrated risk factors for suicide operate by increasing the likelihood of one or more of the theory's constructs. The current study examined the relations of the major constructs of the interpersonal theory with suicide case status compared to living controls in the second half of life. The current study used a pre-existing psychological autopsy database to compare suicide decedents to living controls 50 years and older. Theory constructs were measured by composite scores of thwarted belongingness, perceived burdensomeness, and painful and provocative experiences using an a priori selection of items comprising each construct. Suicide decedents experienced greater levels of all three of the theory's constructs when examined independently compared to living controls. When examined simultaneously while also controlling for Major Depression, greater perceived burdensomeness and painful and provocative experiences were associated with suicide case status (vs. control). The interpersonal theory is a comprehensive framework that may be useful in understanding risk for death by suicide in the second half of life. Clinical management of suicide risk for adults in the second half of life could include a focus on perceived burdensomeness, as the IPTS proposes that this psychological state is amenable to change via therapeutic intervention.

    We report here a forced double suicide by fire. Two burned bodies discovered in the debris of a house fire were identified as a father and his son by odontological findings. In the father, the concentration of carboxyhemoglobin (CO-Hb) in the left ventricle was over 90% and endrin, an organochlorine pesticide, was also detected in the stomach contents. However, 30.5% of CO-Hb in left ventricular blood and gasoline traces from an intratracheal puncture were detected in the son who had been undergoing treatment at a neuropsychiatric clinic. From these results, we determined this case to be a double suicide forced by the father in which the father set a fire with gasoline, thus burning his son to death, and then died in the fire himself after ingestion of Endrin. This case suggests the importance of integration of the results from the detailed forensic pathological and toxicological examinations and the scene investigation.

    Expanded polytetrafluoroethylene (ePTFE) porous material (GORE(®) PRECLUDE(®) Dura Substitute) does not degenerate or deteriorate in vivo, and is currently used as artificial dura mater. This material does not adhere well to the surrounding tissues, but cerebrospinal fluid leakage along the suture line has been observed in several cases. We describe a case of craniotomy for tumor resection performed 14 years after dural repair with ePTFE sheet. Histological examination of the ePTFE sheet revealed that the sheet was structurally intact, with no evidence of tissue adhesion or cellular infiltration. However, collagen deposition was observed around the suture thread. When the suture thread was removed the collagen was also removed, and the original needle hole appeared again. No significant changes were observed in the features of the ePTFE sheet even 14 years postoperatively. The formation of fibrous tissue around the needle hole was important in preventing cerebrospinal fluid leakage.

    2008-05-01

    This study is one of a few that empirically investigated factors that differentiated the physically violent stalker from the nonviolent stalker. Using discriminant analysis, 103 Canadian cases of "simple obsessional" stalking were examined. Overall, the success of the model for classifying cases into one of two groups was 81%. Results revealed that the physically violent stalker is more likely to: (a) have a stronger previous emotional attachment toward their victim; (b) be more highly fixated/obsessed with their victim; (c) have a higher degree of perceived negative affect towards their victim; (d) engage in more verbal threats toward the victim; and (e) have a history of battering/domestic abuse towards the victim. Overall, the variables that best differentiate the physically violent stalker from the nonviolent one appear to characterize underlying themes of anger, vengeance, emotional arousal, humiliation, projection of blame, and insecure attachment pathology.

    2013-12-01

    Following a sexual assault, victims are usually advised to have a medical forensic exam and sexual assault forensic exam kit (SAK). Once completed, the SAK is to be transported by law enforcement to the crime lab for analysis. However, many kits are never transported to the crime lab, thereby preventing forensic evidence obtained in the kit to be used during the prosecutorial process. The current study examined rates of SAK submission for 393 adolescent sexual assault cases in two Midwestern communities and explored what factors predicted law enforcement officers' submission of SAKs to the crime lab for analysis. Findings reveal that more than 40% of the adolescent cases did not have their SAK submitted, and several factors, including the age and race of the victim, the number of perpetrators in the assault, and the number of assaultive acts, predicted SAK submission. Implications for SAK community protocols are discussed.

    We have examined a 5th to 6th century inhumation from Great Chesterford, Essex, UK. The incomplete remains are those of a young male, aged around 21–35 years at death. The remains show osteological evidence of lepromatous leprosy (LL) and this was confirmed by lipid biomarker analysis and ancient DNA (aDNA) analysis, which provided evidence for both multi-copy and single copy loci from the Mycobacterium leprae genome. Genotyping showed the strain belonged to the 3I lineage, but the Great Chesterford isolate appeared to be ancestral to 3I strains found in later medieval cases in southern Britain and also continental Europe. While a number of contemporaneous cases exist, at present, this case of leprosy is the earliest radiocarbon dated case in Britain confirmed by both aDNA and lipid biomarkers. Importantly, Strontium and Oxygen isotope analysis suggest that the individual is likely to have originated from outside Britain. This potentially sheds light on the origins of the strain in Britain and its subsequent spread to other parts of the world, including the Americas where the 3I lineage of M. leprae is still found in some southern states of America.

    In sinus floor augmentation of an atrophic posterior maxilla, platelet-rich fibrin (PRF) has been used as a graft material. We herein report two cases with histological evaluations of PRF after the surgery. The first case was a 28-year-old female with an atrophic right posterior maxilla who was treated with sinus floor augmentation and simultaneous implant placement using PRF as the sole graft material in our hospital. Twenty-four months after surgery, the implant was unfortunately removed because of occlusal overloading by parafunctional habits. During implant replacement, a tissue sample was obtained from the site of augmentation with PRF and was evaluated histologically. The second case was a 58-year-old man with severe alveolar atrophy of the right maxilla who underwent lateral sinus augmentation using only PRF in a two-stage procedure in our hospital. Samples were obtained at the second-stage surgery and histological examinations were performed. As a result, new bone formation was confirmed histologically in both cases. Our findings show that the use of PRF as a graft material during sinus floor augmentation induces natural bone regeneration. PMID:27795860

    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

    The current study re-examines an exceptional case of a serial killer incarcerated since a decade ago. "Jacob" is the first serial killer apprehended in Israel. His known actions were committed during the eighties of the last century, and continued for eleven years. The victims were elderly individuals, including both his parents. Shortly after incarceration he became overtly schizophrenic and underwent five hospitalisations. The case is re-examined in view of changes, both in the perpetrator's diagnosis and criminal legislation. Was Jacob doomed to become a serial killer, or could his fate be avoided through early professional intervention? Were the killings presenting symptoms of a psychotic or pre-psychotic phase? Should he be eligible for a retrial? What would have been his position with the current law in view of the new 300A(a) clause ("Reduced Punishment") of the Israeli Criminal Code? Could he ever be released back to the community? These are some of the questions to be addressed.

    Focal epithelial hyperplasia (FEH), or Heck’s disease, is a rare disease of the oral mucosa associated with infection by some subtypes of human papilloma virus, especially subtypes 13 or 32. The disease is predominantly found in children and adolescents with indigenous heritage, but other ethnic groups can be affected worldwide. To the best of the authors’ knowledge, it has not been reported in Brazil’s elderly population. This article describes a case of FEH in a 57-year-old Brazilian patient presenting since childhood, with multiple lesions in the lips, buccal mucosa and tongue. The solitary tongue lesion underwent excisional biopsy and the histopathological analysis showed parakeratosis, acanthosis, rete pegs with a club-shaped appearance, koilocytosis and the presence of mitosoid cells. These microscopic findings in conjunction with clinical presentation were sufficient to establish the accurate diagnosis of FEH. Polymerase chain reaction (PCR) was performed, but no one human papillomavirus (HPV) subtype could be identified. Clinicians must be aware of this rare oral disease, which can even affect elderly patients, as we described here. Treatment may be indicated in selected cases due to esthetic and/or functional problems. PMID:26985258

    Cave environments are characterized by possessing specialized fauna living in high environmental stability with limited food conditions. These fauna are highly vulnerable to impacts, because this condition can frequently be easily altered. Moreover, environmental determinants of the biodiversity patterns of caves remain poorly understood and protected. Therefore, the main goal of this work is to propose a cave conservation priority index (CCPi) for a rapid assessment for troglobiotic and troglophile protection. Furthermore, the troglobiotic diversity, distribution and threats have been mapped in the Brazilian Atlantic forest. To propose the CCPi, the human impacts and richness of troglobiotic and troglophile species of 100 caves were associated. Data related to troglomorphic/troglobiotic fauna from another 200 caves were used to map the troglobiotic diversity and distribution. The CCPi reveals extremely high conservation priority for 15% of the caves, high for 36% and average for 46% of the caves. Fourteen caves with extremely high priorities should have urgent conservation and management actions. The geographical distribution of the 221 known troglobiotic/troglomorphic species allowed us to select 19 karst areas that need conservation actions. Seven areas were considered to have urgent priority for conservation actions. The two richest areas correspond to the "iron quadrangle" with iron ore caves (67 spp.) and the "Açungui limestone group" (56 spp.). Both areas have several caves and are important aquifers. The use of the CCPi can prevent future losses because it helps assessors to select caves with priorities for conservation which should receive emergency attention in relation to protection, management and conservation actions.

  2. Embracing Uncertainty: A Case Study Examination of How Climate Change is Shifting Water Utility Planning

    Climate change has emerged as one of the greatest challenges facing water utilities' planning for the future, adding a new source and level of complexity that is forcing many agencies to re-examine their decision-making processes. A significant barrier for many agencies is figuring out how to consider highly uncertain climate information and move away from deterministic thinking to make climate-informed decisions. To provide water professionals with practical and relevant information, the Water Utility Climate Alliance teamed up with the American Water Works Association, in coordination with the Water Research Foundation and Association of Metropolitan Water Agencies, to develop a white paper sharing insights into how and why water agencies are modifying planning and decision-making processes. The 13 case studies presented illustrate the variety of ways in which utilities are incorporating climate change into planning, from immediate operational decisions, to capital planning and asset management, to long-term supply planning.

    A patient diagnosed with early squamous-cell carcinoma (SCC) with microinvasion was treated by surgical excision followed by histopathologic evaluation. During surgery, all the nodes appeared free of tumor other than a single level-3 node which looked suspicious and enlarged. Surprisingly, the node, instead of showing SCC showed features suggestive of “etastatic papillary thyroid carcinoma.” The characteristics of papillary thyroid carcinoma (PTC), their usual histopathologic features and treatment are discussed. The aim of this paper is to present the case of a patient with dual malignancy—oral SCC and PTC in an adult male, which was diagnosed accidently because the protocol of complete surgery and extensive sampling for pathologic examination was followed and thus emphasizes on the necessity for the same.

    One of the major issues that Greek Higher Education Institutes face is the delayed completion of studies of their students. For example, in the case of the Technological Educational Institute of Athens, in the academic year 2012-2013, the percentage of graduates with a length of studies of more than 6 years was 53%. This "problem" becomes harder if we consider that according to the new legislation, the Greek Higher Education Institutes (HEI) must cut off access to the students who "linger" too long. This means that many of these graduates wouldn't be able to complete their studies. While many institutes have systems to quantify and report the length of studies of all graduates, far less attention is typically paid to each student's reason(s) for delayed graduation. In this paper, we focus on examining the question of why students delay in the completion of their studies using several data mining techniques. Through the application of data mining techniques new knowledge will be provided to the administration of a HEI that could be used for solving this problem. The data used in our case study come from a questionnaire distributed to graduates of the institute but also from educational data stored in the Institute's student database.

    A human dog bite-related fatality generally refers to death proximately caused by trauma from a dog's teeth and jaws. According to The Humane Society of the United States, more than 300 individuals died of dog attacks in the United States between 1979 and 1996. Children <12 and elders >70 years represent the typical victims. Pit bull-type dogs, Rottweilers, and German Shepherds constitute the majority of canines implicated in these fatalities.This is a 15-year (1991-2005) retrospective review of dog bite-related fatalities undergoing medicolegal investigation in Kentucky. Of the 11 deaths, 10 consisted of multiple bite marks and blunt force injuries of the head and neck, trunk, and extremities. In 1 case, an asplenic victim's immediate cause of death was bacterial sepsis secondary to a dog bite. Individuals ranged between 14 months and 87 years; 7 (63.6%) were < or =6 years; 10 (90.9%) individuals were white, and 8 (72.7%) were male. Forensic odontological examinations were performed on the dogs in 4 cases. The requisite multidisciplinary investigation includes a detailed assessment of the scene, the victim, and dog or dogs suspected in the attack.

    Introduction Assessment of cardiovascular cases in practical exit exam is limited to simple history taking and physical examination. Standards of assessment are not uniform. This makes assessment less valid and reliable. Aim To explore the perceptions of Internees and General Medicine Examiners about current practices in Cardio Vascular system (CVS) case presentation in final MBBS exit exams and the necessity to change some of the practices. Materials and Methods A set questions pertaining to the preparation for exams, validity, reliability, feasibility and educational impact were prepared to guide in obtaining the perceptions of internees and internal medicine examiners. Focus group discussions were conducted. Data Analysis was done by immersion-crystallization process. Results Most of the internees admitted to feeling concerned because of difficulty in diagnosing murmurs by auscultation. Most of the examiners felt concerned about the logistics involved in arranging practical exams. Both admitted to the lack of uniform standards in assessment. Both agreed that the present system thrived as it was relatively feasible. Some internees suggested that the exam may be conducted in two parts by splitting the syllabus instead of once. Some internees suggested incorporating a student-doctor program to improve practical skills just like the on-going student nurse program. Conclusion There is a need for overhauling the assessment of cardiovascular system in final MBBS summative exams towards one aligned to the competencies as required in an Indian Medical Graduate. Blueprinting of practical assessment with due weightage assigned to epidemiologically important topics is the need of the hour. PMID:26816933

    The Structured Interview of Reported Symptoms (SIRS; Rogers et al., Structured interview of reported symptoms (SIRS) and professional manual, 1992) is a well-validated psychological measure for the assessment of feigned mental disorders (FMD) in clinical, forensic, and correctional settings. Comparatively little work has evaluated its usefulness in compensation and disability contexts. The present study examined SIRS data from 569 individuals undergoing forensic neuropsychiatric examinations for the purposes of workers' compensation, personal injury, or disability proceedings. Using bootstrapping comparisons, three primary groups were identified: FMD, feigned cognitive impairment (FCI), genuine-both (GEN-Both) that encompasses both genuine disorders (GEN-D) and genuine-cognitive presentation (GEN-C). Consistent with the SIRS main objective, very large effect sizes (M Cohen's d = 1.94) were observed between FMD and GEN-Both groups. Although not intended for this purpose, moderate to large effect sizes (M d = 1.13) were found between FCI and GEN-Both groups. An important consideration is whether SIRS results are unduly affected by common diagnoses or clinical conditions. Systematic comparisons were performed based on common disorders (major depressive disorder, PTSD, and other anxiety disorders), presence of a cognitive disorder (dementia, amnestic disorder, or cognitive disorder NOS), or intellectual deficits (FSIQ < 80). Generally, the magnitude of differences on the SIRS primary scales was small and nonsignificant, providing evidence of the SIRS generalizability across these diagnostic categories. Finally, the usefulness of the SIRS improbable failure-revised (IF-R) scale was tested as a FCI screen. Although it has potential in ruling out genuine cases, the IF-R should not be used as a feigning screen.

    Understanding sources of performance bias in science assessment provides important insights into whether science curricula and/or assessments are valid representations of student abilities. Research investigating assessment bias due to factors such as instrument structure, participant characteristics, and item types are well documented across a variety of disciplines. However, the relationships among these factors are unclear for tasks evaluating understanding through performance on scientific practices, such as explanation. Using item-response theory (Rasch analysis), we evaluated differences in performance by gender on a constructed-response (CR) assessment about natural selection (ACORNS). Three isomorphic item strands of the instrument were administered to a sample of undergraduate biology majors and nonmajors (Group 1: n = 662 [female = 51.6%]; G2: n = 184 [female = 55.9%]; G3: n = 642 [female = 55.1%]). Overall, our results identify relationships between item features and performance by gender; however, the effect is small in the majority of cases, suggesting that males and females tend to incorporate similar concepts into their CR explanations. These results highlight the importance of examining gender effects on performance in written assessment tasks in biology. PMID:26865642

    The origins, courses and relations of lateral femoral cutaneous nerves (LFCNs) were examined bilaterally in 28 cadavers, and the variations were observed in two. On the right side of one cadaver, the ventral rami of the first and second lumbar spinal nerves were united and then this nerve was divided into four branches. From medial to lateral, these branches were the obturator nerve, the femoral nerve, the medially located LFCN and the laterally located LFCN. On the left side of another cadaver, there were three LFCNs. All of these nerves pierced the psoas major muscle anterolaterally. Two of these nerves, which pierced the psoas major muscle more proximally than the third, united with each other by a communicating branch anterior to the iliacus muscle. These types of variations are very important, especially in the presence of paresthesias or pain in the anterior thigh, lateral thigh and gluteal region. In these cases, surgeons must always remember the possible variations of the LFCN during surgical procedures in order to prevent injury and the occurrence of meralgia paresthetica.

    Increasing concerns on resource depletion and environmental pollution have largely obliged electrical and electronic waste (e-waste) should be tackled in an environmentally sound manner. Recycling process development is regarded as the most effective and fundamental to solve the e-waste problem. Based on global achievements related to e-waste recycling in the past 15 years, we first propose a theory to design an e-waste recycling process, including measuring e-waste recyclability and selection of recycling process. And we summarize the indicators and tools in terms of resource dimension, environmental dimension, and economic dimension, to examine the e-waste recycling process. Using the sophisticated experience and adequate information of e-waste management, spent lithium-ion batteries and waste printed circuit boards are chosen as case studies to implement and verify the proposed method. All the potential theory and obtained results in this work can contribute to future e-waste management toward best available techniques and best environmental practices.

  12. Understanding lesbians' healthcare behaviour: the case of breast self-examination.

    2003-01-01

    Lesbians' risk of breast cancer is a much-debated issue in health research because lesbians are believed to be at higher risk of the disease than are heterosexual women. This belief is based upon particular risk factors for breast cancer, which are said to be more prevalent in lesbians; and upon differences in preventive health behaviours: in particular, lesbians are said to be less likely to practise breast self-examination (BSE). This paper presents data collected as part of the UK Lesbians and Healthcare Survey (n = 1066) focusing on lesbians who report never practising BSE (n = 218, 20%) and the explanations they offer for their healthcare behaviours. It identifies six types of explanation for not practising BSE: (i) "I don't know what I'm looking for"; (ii) "I've never got into the habit"; (iii) "I'm frightened in case I find something"; (iv) "I don't think I'm at much risk"; (v) "I'm uncomfortable with my body"; and (vi) "My partner does it for me". These findings are important for increasing understanding of lesbians' healthcare behaviour and for developing health promotion materials relevant to their needs.

    PubMed

    Silva, Sílvio Éder Dias da; Camargo, Brigido Vizeu; Padilha, Maria Itayra

    2011-01-01

    This study aimed to examine methodological issues in the theses and dissertations that used social representations theory (SRT) in Brazilian nursing. Twenty-two dissertations and 44 theses were considered. Categorical content analysis was applied, based on five aspects: objects studied, place of SRT, the number of study participants, data collection techniques and data analysis. The predominance of case studies and use, especially of semi-structured interviews, although relevant to the study of SR, do not sufficiently consider the extent of suck knowledge sharing in society. One must take into account lay knowledge to understand health care contextualized studies on health care.

  1. 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.

  2. Clinical aspects of envenomation caused by Tityus obscurus (Gervais, 1843) in two distinct regions of Pará state, Brazilian Amazon basin: a prospective case series

    PubMed Central

    2014-01-01

    Background Scorpion envenomations are a major public health problem in Brazil, whose most dangerous cases are attributable to the genus Tityus. This study was designed to compare the clinical and demographic features of envenomations by Tityus obscurus in two areas of the state of Pará located in the Amazon basin. Were compared demographic findings, local and systemic signs and symptoms of human envenomations caused by T. obscurus that occurred in western and eastern areas of the state. Results Forty-eight patients with confirmed envenomation by T. obscurus were evaluated from January 2008 to July 2011. Most of them came from the eastern region, where male and female patients were present in similar numbers, while males predominated in the west. Median age groups were also similar in both areas. Most scorpion stings took place during the day and occurred significantly more frequently on the upper limbs. The time between the sting and admission to the health center was less than three hours in both areas. Most eastern patients had local manifestations while in the west, systemic manifestations predominated. Local symptoms were similar in both areas, but systemic signs and symptoms were more common in the west. Symptoms frequently observed at the sting site were local and radiating pain, paresthesia, edema, erythema, sweating, piloerection and burning. The systemic manifestations were significantly higher in patients from the west. Futhermore, neurological symptoms such as general paresthesia, ataxia, dysarthria, myoclonus, dysmetria, and electric shock-like sensations throughout the body were reported only by patients from the west. Conclusion The present study shows that two regions of Para state differ in the clinical manifestations and severity of confirmed envenomation by T. obscurus which suggests a toxicity variation resulting from the diversity of T. obscurus venom in different areas of the Brazilian Amazon basin, and that T. serrulatus antivenom can be

  3. Examining small "c" creativity in the science classroom: Multiple case studies of five high school teachers

    NASA Astrophysics Data System (ADS)

    Lasky, Dorothea Shawn

    As the US continues to strive toward building capacity for a workforce in STEM fields (NSF, 2006), educational organizations and researchers have constructed frameworks that focus on increasing competencies in creativity in order to achieve this goal (ISTE, 2007; Karoly & Panis, 2004; Partnership for 21st Century Skills, 2007). Despite these recommendations, many teachers either do not believe in the relevance of nurturing creativity in their students (Kaufman & Sternberg, 2007) or accept the importance of it, but do not know how best to foster it in their classrooms (Kampylis et al., 2009). Researchers conclude that teachers need to revise their ideas about the kind of creativity they can expect from their students to reflect the idea of small 'c' versus large 'C' creativity. There is a dearth of literature that looks closely at teacher practice surrounding creativity in the US and gives teachers a set of practical suggestions they can follow easily. I examined five case studies of teachers as they participated in and implemented a large-scale, NSF-funded project premised on the idea that training teachers in 21 st century pedagogies, (for example, problem-based learning), helps teachers create classrooms that increase science competencies in students. I investigated how teachers' curricular choices affect the amount of student creativity produced in their classrooms. Analysis included determining CAT scores for student products and continua scores along the Small 'c' Creativity Framework. In the study, I present an understanding of how teachers' beliefs influence practice and how creativity is fostered in students through various styles of teacher practice. The data showed a relationship between teachers' CAT scores, framework scores, and school context. Thus, alongside CAT, the framework was determined to be a successful tool for understanding the degree to which teachers foster small 'c' creativity. Other themes emerged, which included teachers' allotment of

  15. Using death certificates and medical examiner records for adolescent occupational fatality surveillance and research: a case study.

    PubMed

    Rauscher, Kimberly J; Runyan, Carol W; Radisch, Deborah

    2012-01-01

    Death certificates and medical examiner records have been useful yet imperfect data sources for work-related fatality research and surveillance among adult workers. It is unclear whether this holds for work-related fatalities among adolescent workers who suffer unique detection challenges in part because they are not often thought of as workers. This study investigated the utility of using these data sources for surveillance and research pertaining to adolescent work-related fatalities. Using the state of North Carolina as a case study, we analyzed data from the death certificates and medical examiner records of all work-related fatalities data among 11- to 17-year-olds between 1990-2008 (N = 31). We compared data sources on case identification, of completeness, and consistency information. Variables examined included those on the injury (e.g., means), occurrence (e.g., place), demographics, and employment (e.g., occupation). Medical examiner records (90%) were more likely than death certificates (71%) to identify adolescent work-related fatalities. Data completeness was generally high yet varied between sources. The most marked difference being that in medical examiner records, type of business/industry and occupation were complete in 72 and 67% of cases, respectively, while on the death certificates these fields were complete in 90 and 97% of cases, respectively. Taking the two sources together, each field was complete in upward of 94% of cases. Although completeness was high, data were not always of good quality and sometimes conflicted across sources. In many cases, the decedent's occupation was misclassified as "student" and their employer as "school" on the death certificate. Even though each source has its weaknesses, medical examiner records and death certificates, especially when used together, can be useful for conducting surveillance and research on adolescent work-related fatalities. However, extra care is needed by data recorders to ensure that

  16. The Absence of CYP3A5*3 Is a Protective Factor to Anticonvulsants Hypersensitivity Reactions: A Case-Control Study in Brazilian Subjects

    Although aromatic anticonvulsants are usually well tolerated, they can cause cutaneous adverse drug reactions in up to 10% of patients. The clinical manifestations of the antiepileptics-induced hypersensitivity reactions (AHR) vary from mild skin rashes to severe cutaneous drug adverse reactions which are related to high mortality and significant morbidity. Genetic polymorphisms in cytochrome P450 genes are associated with altered enzymatic activity and may contribute to the risk of AHR. Here we present a case-control study in which we genotyped SNPs of CYP2C19, 2C9 and 3A5 of 55 individuals with varying severities of AHR, 83 tolerant, and 366 healthy control subjects from São Paulo, Brazil. Clinical characterization was based on standardized scoring systems and drug patch test. All in vivo investigation followed the ENDA (European Network of Drug Allergy) recommendations. Genotype was determined by real time PCR using peripheral blood DNA as a template. Of all 504 subjects, 65% were females, 45% self-identified as Afro-American, 38% as Caucasian and 17% as having non-African mixed ascendancy. Amongst 55 subjects with AHR, 44 had severe cutaneous drug adverse reactions. Of the 46 drug patch tests performed, 29 (63%) were positive. We found a strong association between the absence of CYP3A5*3 and tolerant subjects when compared to AHR (p = 0.0002, OR = 5.28 [CI95% 2.09–14.84]). None of our groups presented positive association with CYP2C19 and 2C9 polymorphisms, however, both SNPs contributed to separation of cases and tolerants in a Classification and Regression Tree. Our findings indicate that drug metabolism genes can contribute in the tolerability of antiepileptics. CYP3A5*3 is the most prevalent CYP3A5 allele associated with reduced enzymatic function. The current study provides evidence that normal CYP3A5 activity might be a protective factor to aromatic antiepileptics-induced hypersensitivity reactions in Brazilian subjects. PMID:26291084

    McCunney, Robert J; Morfeld, Peter; Colby, W David; Mundt, Kenneth A

    2015-01-01

    Renewable energy demands have increased the need for new wind farms. In turn, concerns have been raised about potential adverse health effects on nearby residents. A case definition has been proposed to diagnose "Adverse Health Effects in the Environs of Industrial Wind Turbines" (AHE/IWT); initially in 2011 and then with an update in 2014. The authors invited commentary and in turn, we assessed its scientific merits by quantitatively evaluating its proposed application. We used binomial coefficients to quantitatively assess the potential of obtaining a diagnosis of AHE/IWT. We also reviewed the methodology and process of the development of the case definition by contrasting it with guidelines on case definition criteria of the USA Institute of Medicine. The case definition allows at least 3,264 and up to 400,000 possibilities for meeting second- and third-order criteria, once the limited first-order criteria are met. IOM guidelines for clinical case definitions were not followed. The case definition has virtually no specificity and lacks scientific support from peer-reviewed literature. If applied as proposed, its application will lead to substantial potential for false-positive assessments and missed diagnoses. Virtually any new illness that develops or any prevalent illness that worsens after the installation of wind turbines within 10 km of a residence could be considered AHE/IWT if the patient feels better away from home. The use of this case definition in the absence of a thorough medical evaluation with appropriate diagnostic studies poses risks to patients in that treatable disorders would be overlooked. The case definition has significant potential to mislead patients and its use cannot be recommended for application in any health-care or decision-making setting.

    2008-05-01

    Although professional surveys suggest that the Personality Assessment Inventory (PAI; Morey, 1991) is a popular instrument among forensic and correctional psychologists, relatively little is known about the specific types of legal cases in which it is applied, the particular types of questions it is used to address, or the extent to which its admissibility has been at issue in court cases. Using a comprehensive legal database, we surveyed all published U.S., Canadian, European, and Australian criminal and civil cases in which the PAI was administered. The PAI appears to be introduced by examiners in a wide variety of civil (e.g., child custody, personal injury) and criminal (e.g., insanity, competence) cases to aid in the assessment of a broad range of psychopathology. Additionally, the PAI seems to be used frequently to assess questions concerning potential dissimulation and response styles. Surprisingly, the admissibility of the PAI into evidence was never at issue in any of the cases reviewed.

    Finnish-speaking children with specific language impairment (SLI, N = 15, M age = 5;2), a group of same-age typically developing peers (TD-A, N = 15, M age = 5;2) and a group of younger typically developing children (TD-Y, N = 15, M age = 3;8) were compared in their use of accusative, partitive, and genitive case noun suffixes. The children with SLI were less accurate than both groups of TD children in case marking, suggesting that their difficulties with agreement extend to grammatical case. However, these children were also less accurate in making the phonological changes in the stem needed for suffixation. This second type of error suggests that problems in morphophonology may constitute a separate problem in Finnish SLI. PMID:25995529

    Individuals with primary progressive aphasia (PPA) suffer a gradual decline in communication ability as a result of neurodegenerative disease. Language treatment shows promise as a means of addressing these difficulties but much remains to be learned with regard to the potential value of treatment across variants and stages of the disorder. We present two cases, one with semantic variant of PPA and the other with logopenic PPA, each of whom underwent treatment that was unique in its focus on training self-cueing strategies to engage residual language skills. Despite differing language profiles and levels of aphasia severity, each individual benefited from treatment and showed maintenance of gains as well as generalization to untrained lexical items. These cases highlight the potential for treatment to capitalize on spared cognitive and neural systems in individuals with PPA, improving current language function as well as potentially preserving targeted skills in the face of disease progression.

    We report herein the case of a giant lipoma of the greater omentum that was treated by laparoscopic surgery. A 71-year-old male patient was admitted with a diagnosis of sigmoid colon cancer. During preoperative examination, a gallbladder stone and an intra-abdominal giant lipoma were accidentally diagnosed. Laparoscopic examination revealed a smooth-surfaced, giant yellow tumor at the lower border of the greater omentum that was unattached to the surrounding organs. After laparoscopic resection of the tumor and cholecystectomy, a 10-cm midline incision was made in the lower abdomen to remove the tumor and the gallbladder. We then performed a sigmoidectomy for sigmoid colon cancer through the same laparotomy. The resected tumor measured 29 x 19 x 3 cm and weighed 1250 g, and a histopathologic examination revealed a benign lipoma. Laparoscopic examination and resection of a giant lipoma of the omentum are particularly useful.

    2013-07-01

    We report a new and rare case of recurrent anencephaly in a family with no other apparent abnormalities. The karyotypes of the family and all affected subjects were normal. Thorough mutational analyses of VANGL1 of chromosome 1p13.1 and FOXN1 of chromosome 17q11-q12, genes that are associated with phenotypes of the anencephaly spectrum, unfortunately did not disclose any DNA variations in an affected fetus of this family. The etiology of recurrent anencephaly in this family is therefore due to mutations in genes yet to be discovered, perhaps of the planar cell polarity pathway, or to possible environmental gestational factors during development.

    Anjos, L A; Ferreira, J A

    2000-01-01

    The physiological workload (PW) involved in garbage collection was assessed in a probabilistic sample of 70 Rio de Janeiro city garbage collectors to determine the adequacy of Brazilian labor legislation regarding classification of work. PW was measured as energy expenditure (EE) and heart rate (HR) during total work time (TT) and actual time (AT) in garbage collection on 4 consecutive days. Median EE values were 288.4 and 319.1 kcal.h-1 during TT and AT, respectively, indicating moderately intense work according to Brazilian legislation. However, PW was considered heavy when work classifications based on individual response to work were used: 1) ratio of EE and resting metabolic rate was above 5.0, indicating heavy workload according to the WHO; 2) mean percentage of maximal EE was higher (36.2 and 41.1% for TT and AT, respectively) than the limit for garbage collection (30%) suggested as maximal for Dutch workers; and 3) percentage of maximal HR reserve was also higher than 30% (32.2 and 37.5% for TT and AT, respectively). These results indicate the need for a revision of the workload classification in the Brazilian legislation to take individual workers' characteristics into account.

    Examines the Brazilian National Alcohol Plan - Proalcohol - which has as its immediate aim, 20% replacement of all gasoline with alcohol. Future plans call for replacement of virtually all gasoline by alcohol and a significant fraction of diesel fuels by 1986. Issues which are looked at separately are: agronomic, industrial (alcohol production), utilization, institutional, social, environmental, and scientific. Economic issues pervade all of these and are considered in the conclusions. There is a brief discussion of methanol production and the lessons for the United States.

    2009-09-01

    Narrative text can be a useful means of identifying injury in routine data collections. An analysis of data from a near real-time emergency department surveillance system (NREDSS) in New South Wales (NSW, Australia) was conducted to determine if sports injuries can be identified from routine narrative text recorded in emergency departments. Around one-third of all emergency department (ED) presentations during 1 September 2003 to 15 February 2007 were identified as injury-related. Narrative text searching of triage nursing assessments using keywords identified between 282 (i.e. football) and 26,944 (i.e. play) potential sports injury presentations depending on the selected sports-related keyword used. Routine narrative text descriptions from triage nurse assessments show promise for the identification of sports injury presentations to EDs. Further work is required regarding in-depth assessment of case detection capabilities and the likelihood of improving the quality of narrative text recorded.

    2011-01-01

    This article addresses open questions about the nature and meaning of the positive association between marriage and well-being, namely, the extent to which it is causal, shared with cohabitation, and stable over time. We relied on data from the National Survey of Families and Households (N = 2,737) and a modeling approach that controls for fixed differences between individuals by relating union transitions to changes in well-being. This study is unique in examining the persistence of changes in well-being as marriages and cohabitations progress (and potentially dissolve) over time. The effects of marriage and cohabitation are found to be similar across a range of measures tapping psychological well-being, health, and social ties. Where there are statistically significant differences, marriage is not always more advantageous. Overall, differences tend to be small and appear to dissipate over time, even when the greater instability of cohabitation is taken into account. PMID:22611285

  17. Examining the Dynamics and Evolution of Scientist-Teacher Partnerships Using Case Studies

    NASA Astrophysics Data System (ADS)

    Walker, B. A.; Hall, M. K.

    2004-12-01

    Partnerships between scientists and teachers bring individuals from different work cultures together to share information, make mutual decisions, achieve common goals, and contribute resources and skills (Gomez et al., 1990.) Because of differences between the cultures of science and teaching, building productive, durable partnerships is a challenge. CATTS (Collaboration to Advance Teaching Technology and Science) is an NSF GK-12 fellowship program that establishes partnerships between graduate and undergraduate CATTS fellows and K-12 teachers. Ideally, these sustainable relationships will increase each partner's knowledge and skill in inquiry-based teaching, the quality and quantity of math and science taught, and the likelihood of initiating future partnerships. We used a case study approach to investigate the dynamics of partnership development in the context of CATTS and why some partnerships evolve successfully and others do not. Data were obtained using classroom observations, journals, surveys, and interviews with fellows and teachers. We found commonalities among case studies that allowed us to identify patterns in partnership evolution, attributes of successful and unsuccessful partnerships, and barriers to their formation. Specific shared goals and expectations were essential, but flexibility was also important as the goals and expectations evolved over time. Role definition was an iterative process that required frequent communication and feedback between partners. Establishing hierarchical roles resulted in intimidation and breakdown of communication. The best partnerships involved a division of labor in the classroom and in planning and collaboration in which each partner's strengths were utilized to supply scientific and pedagogical resources. Investment in the partnership varied as the partnership progressed but was strongest when both partners felt as though their individual contributions were welcomed and appreciated.

    Coastal overwash deposits from tsunamis and storms have been identified and characterised from many coastal environments. To date, these investigations have utilised ad-hoc time, energy and cost intensive invasive techniques, such as, pits and trenches or taking core samples. Here, we present the application of high-frequency ground penetrating radar (GPR) to identify and characterise the 2004 Indian Ocean Tsunami (IOT) and palaeotsunami deposits from Phra Thong Island, Thailand. This site is one of the most intensively studied palaeotsunami sites globally and preserves a series of late-Holocene stacked sandy tsunami deposits within an organic, muddy low-energy backbeach environment. Using 100, 500 and 1000 MHz GPR antennas, 29 reflection profiles were collected from two swales (X and Y) inland of the modern beach, and two common mid-point (CMP) profiles using the 200 MHz antennas were collected from Swale Y. Detailed examination of the CMPs allowed accurate velocity estimates to be applied to each profile. The reflection profiles included across-swale profiles and a high-resolution grid in Swale X, and were collected to investigate the feasibility of GPR to image the palaeotsunami deposits, and two profiles from Swale Y where the tsunami deposits are poorly known. The 500 MHz antennas provided the best stratigraphic resolution which was independently validated from the stratigraphy and sedimentology recovered from 17 auger cores collected along the profiles. It is clear from the augers and GPR data, that the different dielectric properties of the individual layers allow the identification of the IOT and earlier tsunami deposits on Phra Thong Island. Although applied in a coastal setting here, this technique can be applied to other environments where thin sand beds are preserved, in order to prioritise sites for detailed examination.

  19. Exploring Specialized STEM High Schools: Three Dissertation Studies Examining Commonalities and Differences Across Six Case Studies

    NASA Astrophysics Data System (ADS)

    Tofel-Grehl, Colby

    This dissertation is comprised of three independently conducted analyses of a larger investigation into the practices and features of specialized STEM high schools. While educators and policy makers advocate the development of many new specialized STEM high schools, little is known about the unique features and practices of these schools. The results of these manuscripts add to the literature exploring the promise of specialized STEM schools. Manuscript 1¹ is a qualitative investigation of the common features of STEM schools across multiple school model types. Schools were found to possess common cultural and academic features regardless of model type. Manuscript 2² builds on the findings of manuscript 1. With no meaningful differences found attributable to model type, the researchers used grounded theory to explore the relationships between observed differences among programs as related to the intensity of the STEM experience offered at schools. Schools were found to fall into two categories, high STEM intensity (HSI) and low STEM intensity (LSI), based on five major traits. Manuscript 3³ examines the commonalities and differences in classroom discourse and teachers' questioning techniques in STEM schools. It explicates these discursive practices in order to explore instructional practices across schools. It also examines factors that may influence classroom discourse such as discipline, level of teacher education, and course status as required or elective. Collectively, this research furthers the agenda of better understanding the potential advantages of specialized STEM high schools for preparing a future scientific workforce. ¹Tofel-Grehl, C., Callahan, C., & Gubbins, E.

    2011-06-01

    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.

    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.

    2005-06-01

    A case study is used to illustrate how an evaluation strategy was used to assess classroom instructional practices following a multiyear institutional curriculum revision process. From January through April of 2003, twelve faculty in medicine and three faculty in dentistry who taught in the first- and second-year basic science courses within the dental curriculum participated in a qualitative study. The purpose was to use a formative evaluation process to assess the impact of the curriculum revision at the level of classroom instruction. The observations revealed that seventeen of the twenty classes observed were teacher-centered, passive, and lacked observable effort to help students understand the relationship of the lecture content to the oral health problems. Findings illustrate the importance of using formative evaluation as a mechanism to assess change efforts and how evidence-based study can be used to support initiatives directed toward assessing active student learning and problem solving. Raising faculty awareness about the importance of acquiring evidence-based educational skills, aligning instruction with course goals and objectives, formatively assessing teaching, and providing learning experiences that will actually be used in practice are essential to ensuring that active learning and critical thinking are demonstrated in the curriculum.

    Low-lethality weapons are intended to neutralize a person with maximum security and with minimal risk of injury or death to the user of the weapon, the person arrested, and the witnesses. Under the same circumstances, the use of a firearm is causing mortality of 50%. Marketed since 1974, the Taser X26 is currently staffing services in the French police and gendarmerie. The Taser device has 3 damaging mechanisms: the direct effect of electric current on the tissues, the conversion of electrical energy into thermal energy, and the injuries caused by the general muscle contraction and resulting fall. The study aimed to analyze the specificities of the conducted electrical weapon-related injuries treated in a emergency department on a series of 46 cases. The study population was predominantly middle-aged men. The circumstances of use of the Taser X26 were most often related to an arrest. The frequency of consultation after a shot by Taser X26 was stable. The management is essentially an outpatient because of frequent and benign lesions. The impacts of electrical impulse mainly affect the chest and abdomen. This distribution of impact zones is inhomogeneous, depending on the circumstances of use.

    2013-01-01

    The reduction of road crashes and injuries among motorcyclists in Nigeria requires a system inquiry into some safety issues at pre-crash, crash and post-crash stages to guide action plans. This paper examines safety issues such as age restriction, motorcycle engine capacity, highway code awareness, licence holding, helmet usage, crash involvement, rescue and payment for treatment among commercial motorcyclists. The primary data derived from a structured questionnaire administered to 334 commercial motorcyclists in Samaru, Zaria were analysed using descriptive statistics and logistic regression technique. There was total compliance with age restriction and motorcycle engine capacity. About 41.8% of the operators were not aware of the existence of the highway code. The odds of licence holding increased with highway code awareness, education with above senior secondary as the reference category and earnings. The odds of crash involvement decreased with highway code awareness, earnings and mode of operation. About 84% of the motorcyclists did not use crash helmet, in spite of being aware of the benefit, and 65.4% of motorcycle crashes was found to be with other road users. The promotion of safety among motorcyclists therefore requires strict traffic law enforcement and modification of road design to segregate traffic and protect pedestrians.

    Body Tracking Test (BTT) is a testing method of the dynamic body balance function wherein movement of the center of gravity in accordance with a moving visual target stimulus is examined to evaluate the tracking function of the body. The objects were the patients who were diagnosed as having vestibular neuronitis at the Department of Otolaryngology in Toho University medical center Sakura hospital, and were undergoing hospital treatment. Lateral BTT was performed in 31 subjects, and antero-posterior (A-P) BTT in 45 subjects. Although gaze nystagmus was noted, inspection was enforced when a standing position posture was possible. In lateral BTT, the average (cm/second) horizontal direction body sway speed was compared, however, no clear lateral difference was noted. In the antero-posterior (A-P) BTT, it inquired using the direction body sway average center displacement (cm) of X. Deviation was seen by the affected side in stabilometry. Deviation was seen by the unaffected side in the antero-posterior (A-P) BTT. This phenomenon differs from the deviation pattern until now and is considered to involve participation of the higher centers.

    2013-01-01

    Objective This study investigated the antecedents and consequences of gambling passion using structural equation modeling to examine relationships among gambling motivation, passion, emotion, and behavioral intentions in the horse racing industry. Methods An onsite survey was conducted with 447 patrons at a horseracing park in South Korea. A confirmatory factor analysis showed that the Gambling Passion Scale was valid and reliable, resulting in two sub-scales: obsessive passion (OP) and harmonious passion (HP). Results Study results indicated that extrinsic motivation influenced OP whereas intrinsic motivation significantly affected HP. Furthermore, OP was correlated with negative emotion, whereas HP was related to positive emotion. Gamblers' satisfaction was found to be influenced positively by positive emotion and negatively by negative emotion. Finally, satisfaction appeared to affect gamblers' behavioral intentions. Conclusion Study results echoed the notion of distinct and separate gambling motivations and passions among horse racing gamblers. Furthermore, results identified specific areas to which horse racing operators or policy makers should pay special attention in developing effective marketing strategies to promote responsible gambling.

    To better understand risk factors and populations at risk of childhood fatalities, a review of all records of childhood deaths (≤19 years) between 2000 and 2010 from New Mexico's statewide medical examiner was conducted. Annually, 313-383 childhood deaths were investigated (3820 total). Males and American Indians were overrepresented (62% and 20.4% of deaths, respectively). The most common manner of death was natural (44.8%), followed by accidental (31.4%), homicide (8.8%), suicide (8.8%), and undetermined (4.1%). Infants under 1 year of age accounted for 41.4% of deaths. Motor vehicle crashes were responsible for the majority of accidental deaths (69%), followed by unintentional overdoses (6.9%), and drowning (5.3%). Gunshot wounds, either intentional or unintentional, caused 10.7% of childhood deaths. Complete medico-legal investigation of childhood fatalities is needed to provide public health agencies with adequate data to evaluate and prevent childhood deaths.

    The nature of unpaid caregiving is changing significantly in response to the changing nature of families, increased average life expectancy, and the rise in elderly populations. In order to adapt to these challenges, there is an increased focus on the workplace as a source of support for caregiver-employees (CEs), or employees providing unpaid care to a family member or friend while also working in paid employment. As demonstrated by Ireson et al. (2016), a number of workplaces in Canada and abroad are currently showing leadership with respect to the provision of caregiver-friendly workplace policies (CFWPs). The purpose of this study was to explore what is currently being offered to caregiver-employees by Canadian and international workplaces, as well as how these strategies have been defined, developed, introduced, integrated and sustained within the workplace. For the purposes of this study, CEs are defined as individuals engaged in paid employment, while simultaneously serving as an unpaid elder-care provider. To achieve the aims of this paper, a qualitative comparative case study of 21 workplaces was conducted. Participants were recruited via strategies such as snowball sampling, cold-calling and social media blasts. These workplaces, which operate as exemplars in meeting the needs of caregiver-employees, are pivotal to understanding the process which takes place in the implementation and success of CFWPs across various sectors/industries. The results of this study will be used to inform the wide gap in our knowledge about CFWPs while providing the evidence needed to workplaces and other organizations to introduce CFWPs into their employment practices.

    Background Spinal manipulation therapy (SMT) is a popular though controversial practice. The debates surrounding efficacy and risk of SMT are only partially evident in popular discourse. Objective This study aims to investigate the presence of critiques and debates surrounding efficacy and risk of SMT on the social media platform Twitter. The study examines whether there is presence of debate and whether critical information is being widely disseminated. Methods An initial corpus of 31,339 tweets was compiled through Twitter’s Search Application Programming Interface using the query terms “chiropractic,” “chiropractor,” and “spinal manipulation therapy.” Tweets were collected for the month of December 2015. Post removal of tweets made by bots and spam, the corpus totaled 20,695 tweets, of which a sample (n=1267) was analyzed for skeptical or critical tweets. Additional criteria were also assessed. Results There were 34 tweets explicitly containing skepticism or critique of SMT, representing 2.68% of the sample (n=1267). As such, there is a presence of 2.68% of tweets in the total corpus, 95% CI 0-6.58% displaying explicitly skeptical or critical perspectives of SMT. In addition, there are numerous tweets highlighting the health benefits of SMT for health issues such as attention deficit hyperactivity disorder (ADHD), immune system, and blood pressure that receive scant critical attention. The presence of tweets in the corpus highlighting the risks of “stroke” and “vertebral artery dissection” is also minute (0.1%). Conclusions In the abundance of tweets substantiating and promoting chiropractic and SMT as sound health practices and valuable business endeavors, the debates surrounding the efficacy and risks of SMT on Twitter are almost completely absent. Although there are some critical voices of SMT proving to be influential, issues persist regarding how widely this information is being disseminated. PMID:27637456

    This study examined the muscle power of Brazilian circumpubertal girls and extended the analysis to a cross-cultural dimension. A total of 462 children, 123 Brazilian girls and 339 French girls, 9-18 years, participated in this investigation. Anthropometric data included body mass (BM), height, skinfold thicknesses, and estimated lean leg volume (LLV). All subjects completed a physical activity questionnaire. Cycling peak power was measured including the flywheel inertia of the device (CPPi). Brazilian girls self-assessed their maturation using pubic hair development. CPPi and optimal velocity (v(opt) = velocity at CPPi) increased with stages of puberty. A multiple stepwise regression with anthropometric variables as explanatory factors showed only LLV and age explaining the variance of CPPi (R2 = 0.40, P < 0.001). Therefore, 60% of the variance of CPPi in Brazilian girls was related to undetermined qualitative individual factors, which may be related to cycling skill. Even when normalized for anthropometric variables, the anaerobic performance (CPPi and v(opt)) of Brazilian girls was significantly lower than a cohort of French girls. The latter demonstrated a high participation in sport and training activities, while 50% of the Brazilian girls had only physical education classes in the form of regular physical activity. Moreover, most of the Brazilian girls demonstrated an ineffective sprint cycling skill. The data suggest that motor learning is an important issue in muscle power assessment and might, therefore, partially explain peak power differences in Brazilian compared with French girls.

    Background This study aims to describe the role of mobility in malaria transmission by discussing recent changes in population movements in the Brazilian Amazon and developing a flow map of disease transmission in this region. Methodology/Principal findings This study presents a descriptive analysis using an ecological approach on regional and local scales. The study location was the municipality of Porto Velho, which is the capital of Rondônia state, Brazil. Our dataset was obtained from the official health database, the population census and an environmental database. During 2000–2007 and 2007–2010, the Porto Velho municipality had an annual population growth of 1.42% and 5.07%, respectively. This population growth can be attributed to migration, which was driven by the construction of the Madeira River hydroelectric complex. From 2010 to 2012, 63,899 malaria-positive slides were reported for residents of Porto Velho municipality; 92% of the identified samples were autochthonous, and 8% were allochthonous. The flow map of patients' movements between residential areas and areas of suspected infection showed two patterns of malaria transmission: 1) commuting between residential areas and the Jirau hydropower dam reservoir, and 2) movements between urban areas and farms and resorts in rural areas. It was also observed that areas with greater occurrences of malaria were characterized by a low rate of deforestation. Conclusions The Porto Velho municipality exhibits high malaria endemicity and plays an important role in disseminating the parasite to other municipalities in the Amazon and even to non-endemic areas of the country. Migration remains an important factor for the occurrence of malaria. However, due to recent changes in human occupation of the Brazilian Amazon, characterized by intense expansion of transportation networks, commuting has also become an important factor in malaria transmission. The magnitude of this change necessitates a new model to

    The Brief Coping Orientation to Problems Experienced (COPE) inventory investigates the different ways in which people respond to stressful situations. Knowledge is lacking regarding the coping strategies and styles of people in developing countries, including Brazil. This study aimed to adapt and validate the Brief COPE to Brazilian Portuguese (named COPE Breve) by focusing on dispositional coping. For the cross-cultural adaptation, the original Brief COPE in English (28 items grouped into 14 subscales) was adapted according to a universalistic approach, following these steps: translation, synthesis, back-translation, analysis by an expert panel, and pretest with 30 participants. Then, 237 adults from the community health service responded to the COPE Breve. Psychometric analyses included reliability and exploratory factor analysis. Most of the 14 subscales from the original Brief COPE exhibited problems related to internal consistency. A Velicer's minimum average partial test (MAP) was performed and pointed out 3 factors. Exploratory factor analysis produced a revised 20-item version with a 3-factor solution: religion and positive reframing, distraction and external support. The psychometric properties of the COPE Breve with three factors were appropriate. Limitations of this study as well as suggestions for future studies are presented. The COPE Breve should be used in Brazilian clinics and investigations, but divergences in its psychometrics should be further explored in other contexts. PMID:27007646

    Dancers are at risk for developing groin pain that is due to acetabular labral tears. Although surgical management of labral tears has been reported extensively, conservative management has been poorly described. This case report describes the examination, diagnosis, and treatment of groin pain in a professional ballet dancer with a suspected acetabular labral tear. Treatment focused on decreasing anterior hip joint stresses and improving the precision of hip motion through correction of alignment and movement impairments noted during functional activities and dance. Successful outcomes included a reduction in pain and return to professional ballet dancing.

    Autosomal dominant polycystic kidney disease is a genetic disorder which results in the development of multiple cysts in the kidneys and other parenchymal organs. The two genes in which mutations are known to cause autosomal dominant polycystic kidney disease are PKD1 and PKD2. Approximately 50% of individuals with autosomal dominant polycystic kidney disease will develop end-stage renal disease by the age of 60. Early stages of the disease are usually asymptomatic and at the moment of establishing a definitive diagnosis, complications and associated disorders, including end-stage renal disease, occur frequently. About 95% of individuals with autosomal dominant polycystic kidney disease have an affected parent and about 5% have a de novo mutation. Each child of an affected individual has a 50% chance of inheriting the mutation. The first symptoms of disease usually develop in the third or fourth decades of life. Imaging examinations of relatives at risk allow for an early detection when no clinical symptoms are present as well as enable treatment of complications and associated disorders. Ultrasound examination as a basic and minimally invasive imaging technique can be easily used in general practice. In the majority of patients with autosomal dominant polycystic kidney disease, sonography allows for a certain and reliable diagnosis of this disease. Additionally, it enables to perform follow-up examinations both of the patient and their family. The possibility of ultrasound imaging in general practice broadens clinical examination and facilitates establishing a proper diagnosis. The paper presents a case report of a patient with autosomal dominant polycystic kidney disease. Its aim was to present the relevance of ultrasound examination in general practice.

    Objectives: Cleidocranial dysplasia (CCD) is a rare congenital malformation syndrome, inherited autosomal-dominantly. During a course of treatment including surgical, implantological and restorative procedures, an opportunity arose to histologically examine biopsies of the maxilla and mandible of a CCD patient 47 years of age. Case report: The aim of this case report is to present the results of the histological evaluation of the alveolar bone and the surgical pretreatment for and placement of six implants each in the maxilla and the mandible. The implants were inserted in a minimally invasive procedure using 3D template guidance. Following uneventful healing of the implants, ceramically veneered bridges were cemented on individual titanium abutments. Since the patient had not received orthodontic treatment in childhood-which would have been the treatment modality of choice-this implantological and prosthodontic approach was necessary. Biopsies were taken from the maxilla and the mandible before placing the implants. Histological evaluation showed bone with strong, coarsely interconnecting trabeculae, especially in the maxilla. Both the bone and the gingiva otherwise exhibited a normal structure without pathological features or anomalies. Conclusion: The clinical parameters and histological evaluation of this one clinical case suggest that the concepts familiar from general oral implantology in terms of surgical and prosthetic procedures can be adopted for older patients with CCD.

    Developmental dental anomalies have been associated with different malocclusions in various populations. This study verified this association in Brazilian non-syndromic orthodontic patients. The prevalence of dental anomalies was evaluated by examining 2,052 pretreatment records of orthodontic patients. Panoramic radiographs, study designs, intraoral photographs and medical history were collected in order to identify hypodontia, hyperdontia, microdontia, macrodontia, taurodontism, transposition, impaction, and ectopia. Epidemiological data and classification of malocclusion were also obtained. Data were analyzed using chi-square and Fisher's exact test (P < 0.05), and the prevalence ratio was obtained from cases that had a significant association between anomaly and malocclusion. The results showed that 27.4% of the patients evaluated had some dental anomaly, and most of them were white women aged 11-20 years. Ectopia, microdontia, impaction, and hypodontia were more prevalent in patients with Class I malocclusion. Macrodontia was the only anomaly associated with Class II division 1. Impaction was associated with Class III malocclusion, at a 1.84-times higher prevalence. In conclusion, impaction was correlated with Class I malocclusion; macrodontia showed association with Class II division 1; and impaction and ectopia were associated with Class III malocclusion in Brazilian orthodontic patients.

    The aim of the present study was to provide new spirometry reference equations in a sample of the Brazilian population for the following parameters: forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/FVC ratio, peak of expiratory flow (PEF), forced expiratory flow at 50% (FEF50%), 75% average vital capacity (FEF25-75%), and average forced expiratory flow time (FEFT). This was a prospective study using results from chest radiographs, electrocardiograms, and questionnaires to investigate the participants' respiratory symptoms, sedentarism, and comorbidities (Charlson comorbidity index). From December 2010 to July 2014, individuals were randomly selected from various locations in the state of Rio de Janeiro. All individuals were examined by a single technician in the morning at the laboratory, and performed the spirometry with the same spirometer. Spirometry values were tabulated for the creation of three equation models: linear regression, logarithmic regression, and logarithms through a method that incorporates the lambda, median, and coefficient of variation (LMS method). Initially, 7003 individuals from both genders were contacted, and 454 were recruited. The data from the new equations were compared with one Brazilian and eight international equations, resulting in a high correlation (r>0.9). The values derived from the LMS method and linear regression were very similar (P>0.5), and both could be used to acquire the reference values for Brazilian spirometry. Data derived from the equations of this study were different from the current Brazilian equation, which could be justified by the different method used.

  1. 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.

    The lack of correlation between the Journal Impact Factors and the most cited Brazilian papers in physics is statistically demonstrated. The existence of an effective "Brazilian Impact Factor" is observed, being its values, in general, lower than the international Impact Factors. In some cases, discrepancies from the international values are huge, leading to doubts on whether it is appropriate to use this indicator to judge Brazilian scientists.

    Brazil`s annual rate of deforestation reached 2.1 million ha or about 13.6% of the total annual rate of deforestation for the whole tropical area in the world during 1981--1990. Today, the extent of gross deforestation is 10.9% of the tropical closed forest area. Relative to Brazilian participation in the greenhouse effect, the changes in forest area and associated biomass burning in Amazon region are responsible for about 25.5% of CO{sub 2} emissions in the tropics. Harvest of the non-timber biomass products may be important as a potentially sustainable use of forest in some areas. An excellent option to promote these biomass products is to provide energy and industrial goods for the Amazon communities and other external markets. In this work, the biofuels produced by vegetable tropical oils and their by-products are analyzed in relation to job creation, economics and environmental impacts, with special regards concerning the limitation of the atmospheric emissions of greenhouse gases.

    This paper analyzes the demographic dynamics of the Kayabí, a Tupi people in the Xingu Indian Reservation in Central Brazil, from 1970 to 2007. Data were gathered from vital statistics for the Xingu Indian Reservation at the Federal University in São Paulo. Contact with Brazilian national society from 1920 to 1950 in the Upper Teles Pires River Valley led to a population decrease due to clashes and epidemics. In 1952, part of the Kayabí group gradually began migrating to the Xingu, where they still live. In 1970 there were 204 Kayabí in Xingu villages, and by 2007 there were 1,162, representing a 4.8% annual growth rate. For 2000-2007 the crude birth rate was 51 per thousand inhabitants; total fertility rate 7.8 children per women; crude death crude 3.5 per thousand inhabitants; and infant mortality rate 17.5 per thousand live births. The majority of the population is under 15 years of age (55.9%). The results show a population recovery process, similar to that of some other indigenous group in Brazil.

    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.

    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.

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

    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.

    This paper reports results obtained in pedagogical interventions in a Brazilian public high school which aimed at promoting a dialogue between scientific and traditional knowledge in the context of biology teaching. The interventions were based on the use of a didactic material and teaching sequence elaborated on the grounds of school knowledge about botany, as presented in biology textbooks, and interviews with students who were also farmers, so as to gather data about their ethnobiological knowledge. Our goal was to develop and test resources that can offer support for teachers who wish to build a dialogue between different ways of knowing in multicultural settings. Our results indicate that the use of the didactic material and teaching sequence indeed created possibilities for a dialogue between the students’ ethnobiological knowledge and biology school knowledge. We observed some shortcomings in classroom practice, partly reflecting our very choice of subject matter to develop the teaching sequence. But the interventions also revealed important limitations that we regard as representative of problems that may generally make multicultural science teaching a hard goal to achieve. It was clear that important shortcomings were related to teachers’ difficulties to conduct a dialogue between ways of knowing in a science classroom, and, thus, called attention to the importance of introducing a multicultural dimension into teacher education. We also observed that the fact that students did not show much sensitivity towards dealing with cultural diversity was a factor constraining the success of the interventions. These results highlight the importance of proposing and testing teacher education initiatives aiming at preparing them to teach science in a culturally sensitive manner, and also managing classroom tensions and conflicts so as to make it possible an effective dialogue between different ways of knowing in a multicultural setting.

  11. Carbon emissions and sequestration in forests: Case studies from seven developing countries. Volume 2, Greenhouse gas emissions from deforestration in the Brazilian Amazon

    1992-08-01

    Deforestation in Brazilian Amazonia in 1990 was releasing approximately 281--282 X 10{sup 6} metric tons (MT) of carbon on conversion to a landscape of agriculture, productive pasture, degraded pasture, secondary forest and regenerated forest in the proportions corresponding to the equilibrium condition implied by current land-use patterns. Emissions are expressed as ``committed carbon,`` or the carbon released over a period of years as the carbon stock in each hectare deforested approaches a new equilibrium in the landscape that replaces the original forest. To the extent that deforestation rates have remained constant, current releases from the areas deforested in previous years will be equal to the future releases from the areas being cleared now. Considering the quantities of carbon dioxide, carbon monoxide, methane, nitrous oxide, NO{sub x} and non-methane hydrocarbons released raises the impact by 22--37%. The relative impact on the greenhouse effect of each gas is based on the Intergovernmental Panel on Climate Change (IPCC) calculations over a 20-year time period (including indirect effects). The six gases considered have a combined global warming impact equivalent to 343 to 386 million MT of C0{sub 2}-equivalent carbon, depending on assumptions regarding the release of methane and other gases from the various sources such as burning and termites. These emissions represent 7--8 times the 50 million MT annual carbon release from Brazil`s use of fossil fuels, but bring little benefit to the country. Stopping deforestation in Brazil would prevent as much greenhouse emission as tripling the fuel efficiency of all the automobiles in the world. The relatively cheap measures needed to contain deforestation, together with the many complementary benefits of doing so, make this the first priority for funds intended to slow global warming.

    The purpose of this study was to gain a better understanding of voluntary associations involved in forest management. The specific areas examined in this study include organizational attributes, membership profile, attitudes toward forest-management priorities, and concerns about forest-management issues. To achieve this purpose, data were collected using a case study approach with mixed-methods (document reviews, personal interviews, and a Web survey) at a national forest in Texas, USA. Overall, the voluntary associations in this study can be described as place-based, small to moderate in scale, activity-oriented, and active groups that are adaptive to sociopolitical and environmental changes. General group members placed high importance on aesthetic, ecological, and recreation management of the national forest. In addition, this study showed five key forest management issues: (1) limited recreation access; (2) financial challenges for forest management; (3) conflict among recreation user groups; (4) inadequate communication by the United States Forest Service to the general public, and (5) sustainability of the forest. Theoretical and managerial implications of the results are discussed.

    It is well established that olfactory dysfunction has significant implications for safety, nutrition, and quality of life. The more reliable standardized tests of olfactory function, such as the University of Pennsylvania Smell Identification Test (UPSIT), assess odor identification ability. Unfortunately, cultural factors can influence such tests, as a number of odors are not universally recognized. In this study, a Portuguese language version of the UPSIT was administered to an age- and sex-stratified prospective sample of 1820 Brazilian subjects. Normative data were developed for a subset of 1578 subjects who reported having no difficulties smelling or tasting. Individuals with a history of head trauma or, in the case of those over the age of 64 years, Mini-Mental State Examination Scores <24, were excluded from analysis. As in other populations, the test scores were significantly influenced by age and sex. The median overall difference between the North American and Brazilian UPSIT scores was 2.2 points for men and 0.8 points for women, although subtle age-related differences were also apparent. This research represents that largest clinical study of olfaction ever performed in South America. Correction factors based upon age and sex are provided to allow for direct comparisons of Brazilian test scores to those based upon North American norms.

    Extranodal natural killer/T-cell lymphoma, nasal type (NK/TCL) is more prevalent in Asia and in some areas of South and Central America, but it is rarely seen in the United States and Europe. In this study, a series of 122 cases of NK/TCL from Brazil was analyzed with respect to clinicopathologic features. Clinical characteristics and geographic distribution were evaluated in 97 cases of nasal/nasopharyngeal region and 23 cases in extranasal sites including 6 nodal cases. Clinical staging and follow-up information was available in a subset of 21 patients. All cases harbored Epstein-Barr virus (EBV), 95% and 85% expressed cytoplasmic CD3 and CD56, respectively, and all cases were positive for at least 1 marker for cytotoxic granules. The global distribution of EBV subtypes showed predominance of strain subtype A, 89%, and subtype B, 11%. No dual infections were detected. TCR-γ TCR-gene rearrangement was observed in 7 cases; all of them extranodal. Three of TCR-γ(+) cases showed EBV subtype A. Two TCR-γ(+)/CD56(+) cases showed EBV subtype B. Geographic distribution of NK/TCL showed higher frequency in the southeast and northeast regions of Brazil. Striking differences among geographic regions were seen with the vast majority of EBV subtype B (86%) occurring in the south and southeast regions.

    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.

  2. Dietary intake of folate, vitamin B6, and vitamin B12, genetic polymorphism of related enzymes, and risk of breast cancer: a case-control study in Brazilian women

    PubMed Central

    2009-01-01

    Background Several studies have determined that dietary intake of B vitamins may be associated with breast cancer risk as a result of interactions between 5,10-methylenetetrahydrofolate reductase (MTHFR) and methionine synthase (MTR) in the one-carbon metabolism pathway. However, the association between B vitamin intake and breast cancer risk in Brazilian women in particular has not yet been investigated. Methods A case-control study was conducted in São Paulo, Brazil, with 458 age-matched pairs of Brazilian women. Energy-adjusted intakes of folate, vitamin B6, and vitamin B12 were derived from a validated Food Frequency Questionnaire (FFQ). Genotyping was completed for MTHFR A1298C and C677T, and MTR A2756G polymorphisms. A logistical regression model was used to calculate odds ratios (ORs) and 95% confidence intervals (95% CIs). Results Neither dietary intake of folate, vitamin B6, or vitamin B12 nor MTHFR polymorphisms were independently associated with breast cancer risk. Analysis stratified by menopausal status showed a significant association between placement in the highest tertile of folate intake and risk of breast cancer in premenopausal women (OR = 2.17, 95% CI: 1.23–3.83; Ptrend = 0.010). The MTR 2756GG genotype was associated with a higher risk of breast cancer than the 2756AA genotype (OR = 1.99, 95% CI = 1.01–3.92; Ptrend = 0.801), and statistically significant interactions with regard to risk were observed between the MTHFR A1298C polymorphism and folate (P = 0.024) or vitamin B6 (P = 0.043), and between the MTHFR C677T polymorphism and folate (P = 0.043) or vitamin B12 (P = 0.022). Conclusion MTHFR polymorphisms and dietary intake of folate, vitamin B6, and vitamin B12 had no overall association with breast cancer risk. However, increased risk was observed in total women with the MTR 2756GG genotype and in premenopausal women with high folate intake. These findings, as well as significant interactions between MTHFR polymorphisms and B vitamins

    Morphometric parameters, acquired notoriety mainly after the Drainage Density proposition (Horton 1932, 1945) and after they were applied by geomorphologists on the perspective to understand landscape functionalities, quantifying their characteristics through parameters and indexes. After the drainage density, many other parameters which describe the basin characteristics, behavior and dynamics have been proposed. Among them, for example, the DEI was proposed by Coelho Netto and contributors during the 80's, while they were seek to understand the hydrological and erosive dynamics on Bananal river basin (Brazilian Southeastern). Through this investigations the DEI was created, revealing the importance of parameters as hollow and drainage density, conjugated to the topographic gradient (Meis et al. 1982) who prosecute controls on the water flow efficiency along the hollows in order to activate the regressive erosion of the main channel. Later on this index was applied on the basin scale in several works developed in mountainous regions, showing a remarkable correlation with the occurrence of landslides such as showed by Coelho Netto et al. (2007); that posteriorly use this index as one of the components of the landslide susceptibility map for the Tijuca Massif, located in Rio de Janeiro Municipality. This work aims to establish patterns of the DEI index values (applied to mountainous low order basins) and the relationship on the occurrence of Debriflows or shallow translational slides. For this, the DEI index was applied on 4 different study areas located on the Southeastern mountainous region of Brazil to address deeply the connection between the index and the occurrence of landslides of different types applied for first and second order basins. The major study area is the Córrego Dantas Basin, situated in Nova Friburgo municipality (RJ), which is a 53 km² basin was affected by 327 landslides caused by a heavy rainfall on January 2011; Coelho Netto et al.

    OBJECTIVE: Epidermal growth factor receptor is involved in the pathogenesis of non-small cell lung cancer and has recently emerged as an important target for molecular therapeutics. The KRAS oncogene also plays an important role in the development of lung cancer. The aim of this study was to evaluate the frequency of epidermal growth factor receptor and KRAS mutations in a population of Brazilian patients with non-small cell lung cancer. METHODS: A total of 207 specimens from Brazilian patients with non-small cell lung cancer were analyzed for activating epidermal growth factor receptor and KRAS somatic mutations, and their associations with clinicopathological characteristics (including age, gender, ethnicity, smoking habits, and histological subtype) were examined. RESULTS: We identified 63 cases (30.4%) with epidermal growth factor receptor mutations and 30 cases (14.6%) with KRAS mutations. The most frequent epidermal growth factor receptor mutation we detected was a deletion in exon 19 (60.3%, 38 patients), followed by an L858R amino acid substitution in exon 21 (27%, 17 patients). The most common types of KRAS mutations were found in codon 12. There were no significant differences in epidermal growth factor receptor or KRAS mutations by gender or primary versus metastatic lung cancer. There was a higher prevalence of KRAS mutations in the non-Asian patients. Epidermal growth factor receptor mutations were more prevalent in adenocarcinomas than in non-adenocarcinoma histological types. Being a non-smoker was significantly associated with the prevalence of epidermal growth factor receptor mutations, but the prevalence of KRAS mutations was significantly associated with smoking. CONCLUSIONS: This study is the first to examine the prevalence of epidermal growth factor receptor and KRAS mutations in a Brazilian population sample with non-small cell lung cancer. PMID:22666783

    2007-01-01

    An important issue that has received insufficient attention in the use of problem-based learning in the medical curriculum is the mode of assessing the level of difficulty of patient cases. In the present study, the level of difficulty of case-based questions in a veterinary degree final examination in reproduction was evaluated. First, cognitive taxonomies were evaluated to clarify whether qualitative methods such as Bloom's taxonomy, the Structure of the Observed Learning Outcome (SOLO) taxonomy, and the Amsterdam Clinical Challenge Scale (ACCS) differed from each other as evaluation tools for problem-based cases. Using these taxonomies, 30 case-based questions from the final examination in reproduction in the Helsinki veterinary program were initially evaluated to determine which one was best suited to the evaluation of the difficulty of cases. In follow-up, the same cases were also evaluated by an experienced veterinary instructor in reproduction, with the aim of gaining insight into using these approaches to evaluating difficulty. It would appear, from this preliminary assessment, that the SOLO taxonomy may be the most suitable for evaluating the difficulty of patient cases, since the instructor's quality rating resembled more closely the SOLO than the Bloom taxonomy or the ACCS. It is to be emphasized that the purpose of this study was to provide a preliminary evaluation of possible approaches that might be used to assess patient-case difficulty. Resolving all issues will require a greater number of evaluations of all components.

  14. The Effect of Examiner Variation in Cartridge Case Acquisition on IBISreg Correlation Scores and the Ability of the System to Return a True Positive

    NASA Astrophysics Data System (ADS)

    Scicchitano, Kristine M.

    When entering cartridge case exhibits into the Integrated Ballistics Identification System (IBISRTM), examiners have the ability to manually manipulate three parameters: lighting intensity, ring selection and exhibit orientation. User guidelines for these settings are subjective, and the effect of examiner variation is largely unknown. If examiner variation negatively affects the returned correlation scores, the ability of the system to return true positives will be compromised. By entering cartridge cases into IBISRTM 88 separate times, using 88 different combinations of parameter settings, the effect of these variables was determined. Analysis of variance testing revealed that no variable has a statistically significant effect on average true positive combined correlation scores or results list position. This did not change when the parameters were tested individually or in combination. Results indicate that examiner variability of cartridge case image acquisition has no effect on the outcome of IBIS RTM. The system's matching algorithm is robust enough to handle exhibit entry and data collection without the intervention of human input. For this reason, acquisition could be completely automated, allowing examiners to focus on the decision making stage of cartridge case comparison.

    Hypermobility of the mandibular condyle may only slightly be influenced by conservative treatment. On the other hand, all surgical methods, except the one described here include a risk factor concerning nerve or blood vessel damage. The present method limits, by plastic surgery, the joint mobility. 28 such operations were checked for results. The cases with recidivating luxation with trismus and blocking of the mandible reacted very favourably. The cases with habitual subluxation without trismus, and the cases with myofacial pain syndrome were not as favorable, objectively seen. Subjectively, however, the patients feel the operation is a success. Further investigation by control checking on late results is indicated.

    OBJECTIVE: The majority of cases of hepatocellular carcinoma have been reported in individuals with cirrhosis due to chronic viral hepatitis and alcoholism, but recently, the prevalence has become increasingly related to nonalcoholic steatohepatitis around the world. The study aimed to evaluate the clinical and histophatological characteristics of hepatocellular carcinoma in Brazilians' patients with nonalcoholic steatohepatitis at the present time. METHODS: Members of the Brazilian Society of Hepatology were invited to complete a survey regarding patients with hepatocellular carcinoma related to nonalcoholic steatohepatitis. Patients with a history of alcohol intake (>20 g/day) and other liver diseases were excluded. Hepatocellular carcinoma diagnosis was performed by liver biopsy or imaging methods according to the American Association for the Study of Liver Diseases' 2011 guidelines. RESULTS: The survey included 110 patients with a diagnosis of hepatocellular carcinoma and nonalcoholic fatty liver disease from nine hepatology units in six Brazilian states (Bahia, Minas Gerais, Rio de Janeiro, São Paulo, Paraná and Rio Grande do Sul). The mean age was 67±11 years old, and 65.5% were male. Obesity was observed in 52.7% of the cases; diabetes, in 73.6%; dyslipidemia, in 41.0%; arterial hypertension, in 60%; and metabolic syndrome, in 57.2%. Steatohepatitis without fibrosis was observed in 3.8% of cases; steatohepatitis with fibrosis (grades 1-3), in 27%; and cirrhosis, in 61.5%. Histological diagnosis of hepatocellular carcinoma was performed in 47.2% of the patients, with hepatocellular carcinoma without cirrhosis accounting for 7.7%. In total, 58 patients with cirrhosis had their diagnosis by ultrasound confirmed by computed tomography or magnetic resonance imaging. Of these, 55% had 1 nodule; 17%, 2 nodules; and 28%, ≥3 nodules. CONCLUSIONS: Nonalcoholic steatohepatitis is a relevant risk factor associated with hepatocellular carcinoma in patients with and

    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.

    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.

    2016-01-01

    Brazilian scientists have been contributing to the protozoology field for more than 100 years with important discoveries of new species such asTrypanosoma 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.

    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.

  4. Intersectorial health-related policies: the use of a legal and theoretical framework to propose a typology to a case study in a Brazilian municipality.

    PubMed

    Tess, Beatriz Helena; Aith, Fernando Mussa Abujamra

    2014-11-01

    This article analyzes intersectorial health-related policies (IHRP) based on a case study performed in 2008-2009 that mapped the social policies of the city of Piracicaba, State of Sao Paulo, Brazil. The research strategy comprised quantitative and qualitative methodologies and converging information sources. Legal and theoretical conceptual frameworks were applied to the Piracicaba study results and served as the basis for proposing a typology of IHRP. Three types of IHRP were identified: health policies where the health sector is coordinator but needs non-health sectors to succeed; policies with a sector other than health as coordinator, but which needs health sector collaboration to succeed; and thirdly, genuine intersectorial policies, not led by any one sector but by a specifically-appointed intersectorial coordinator. The authors contend that political commitment of local authorities alone may not be enough to promote efficient intersectorial social policies. Comprehension of different types of IHRP and their interface mechanisms may contribute to greater efficiency and coverage of social policies that affect health equity and its social determinants positively. In the final analysis,, this will lead to more equitable health outcomes.

    2017-01-01

    Meaningfully synthesizing single case experimental data from intervention studies comprised of individuals with low incidence conditions and generating effect size estimates remains challenging. Seven effect size metrics were compared for single case design (SCD) data focused on teaching speech generating device use to individuals with intellectual and developmental disabilities (IDD) with moderate to profound levels of impairment. The effect size metrics included percent of data points exceeding the median (PEM), percent of nonoverlapping data (PND), improvement rate difference (IRD), percent of all nonoverlapping data (PAND), Phi, nonoverlap of all pairs (NAP), and Taunovlap. Results showed that among the seven effect size metrics, PAND, Phi, IRD, and PND were more effective in quantifying intervention effects for the data sample (N = 285 phase or condition contrasts). Results are discussed with respect to issues concerning extracting and calculating effect sizes, visual analysis, and SCD intervention research in IDD. PMID:27119210

    2015-07-01

    A panel of immunohistochemical markers may be used to differentiate between pagetoid Bowen disease (PBD) and primary extramammary Paget disease (EMPD) in selected cases. Although diffuse staining with cytokeratin 7 (CK7), CAM5.2, carcinoembryonic antigen, epithelial membrane antigen (EMA), and gross cystic disease fluid protein 15 generally supports diagnosis of EMPD, cases have been reported where PBD also expressed CK7, EMA, and CAM5.2. Based on these findings, some authors suggested that the 2 entities may arise from the same multipotent stem cell, capable of further differentiation toward squamous and secretory lines. To the best of our knowledge, this issue has never been investigated by comparing PBD and EMPD at the ultrastructural level. We performed the first ultrastructural study of a case of PBD exhibiting common immunohistochemical features with EMPD. The lesion displayed some ultrastructural features often observed in Bowen disease and some that are typically found in EMPD. These findings indicate the presence of a bidirectional differentiation--secretory and squamous--within the same lesion, thus supporting the hypothesis that PBD and primary EMPD may arise from a common progenitor cell.

    Meta-cognitive strategy training may be used to augment inpatient rehabilitation to promote active engagement and subsequent benefit for individuals with cognitive impairments after stroke. We examined the feasibility of administering a form of meta-cognitive strategy training, Cognitive Orientation to daily Occupational Performance, during inpatient rehabilitation. We trained an individual with cognitive impairments after right hemisphere stroke to identify performance problems, set self-selected goals, develop plans to address goals, and evaluate performance improvements. To assess feasibility, we examined the number of meta-cognitive training sessions attended, the number of self-selected goals, and changes in goal-related performance. We also examined changes in rehabilitation engagement and disability. The participant used the meta-cognitive strategy to set 8 goals addressing physically-oriented, instrumental, and work-related activities. Mean improvement in Canadian Occupational Performance Measure Performance Scale scores was 6.1. Pittsburgh Rehabilitation Participation Scale scores (measuring rehabilitation engagement) improved from 3.2 at admission to 4.9 at discharge. Functional Independence Measure scores (measuring disability) improved from 68 at admission, to 97 at discharge. Performance Assessment of Self-care Skills scores improved from 1.1 at admission to 2.9 at discharge. The results indicate that meta-cognitive strategy training was feasible during inpatient rehabilitation and warrants further evaluation to determine its effectiveness. PMID:21391121

  8. ‘Shell shock’ Revisited: An Examination of the Case Records of the National Hospital in London

    Linden, Stefanie Caroline; Jones, Edgar

    2014-01-01

    During the First World War the National Hospital for the Paralysed and Epileptic, in Queen Square, London, then Britain’s leading centre for neurology, took a key role in the treatment and understanding of shell shock. This paper explores the case notes of all 462 servicemen who were admitted with functional neurological disorders between 1914 and 1919. Many of these were severe or chronic cases referred to the National Hospital because of its acknowledged expertise and the resources it could call upon. Biographical data was collected together with accounts of the patient’s military experience, his symptoms, diagnostic interpretations and treatment outcomes. Analysis of the notes showed that motor syndromes (loss of function or hyperkinesias), often combined with somato-sensory loss, were common presentations. Anxiety and depression as well as vegetative symptoms such as sweating, dizziness and palpitations were also prevalent among this patient population. Conversely, psychogenic seizures were reported much less frequently than in comparable accounts from German tertiary referral centres. As the war unfolded the number of physicians who believed that shell shock was primarily an organic disorder fell as research failed to find a pathological basis for its symptoms. However, little agreement existed among the Queen Square doctors about the fundamental nature of the disorder and it was increasingly categorised as functional disorder or hysteria. PMID:25284893

  9. Gamma-hydroxybutyrate concentrations in the blood of impaired drivers, users of illicit drugs, and medical examiner cases.

    2007-01-01

    Gamma-hydroxybutyrate (GHB) was determined in blood samples from impaired drivers, people arrested for petty drug offenses (non-traffic cases), and GHB-related deaths. The method of analysis involved conversion of GHB into gamma-butyrolactone and determination of the latter by gas chromatography with a flame ionization detector, and with gamma-valerolactone as the internal standard. The mean and median concentrations of GHB in blood from impaired drivers (N=473) were 90 and 84 mg/L, respectively, and offenders were predominantly men (96%) with an average age of 26 year (range 15-50 year). In 185 cases, GHB was the only drug present in blood at mean and median concentrations of 92 and 86 mg/L, respectively. People arrested for petty drug offenses (N=1061) had slightly higher GHB concentrations in their blood: median 118 mg/L for men and 111 mg/L for women. In GHB-related deaths (N=33), the mean and median concentrations were considerably higher: 307 mg/L and 190 mg/L, respectively, and the highest was 2200 mg/L. The typical signs of drug influence noted by the arresting police officers included sedation, agitation, slurred speech, irrational behaviour, jerky movements, and spitting. The short elimination half-life of GHB means that the concentrations in blood decrease rapidly and are probably a lot lower than at the time of driving, which was 30-90 min earlier.

  10. Nonlinear Heart Rate Variability features for real-life stress detection. Case study: students under stress due to university examination

    PubMed Central

    2011-01-01

    Background This study investigates the variations of Heart Rate Variability (HRV) due to a real-life stressor and proposes a classifier based on nonlinear features of HRV for automatic stress detection. Methods 42 students volunteered to participate to the study about HRV and stress. For each student, two recordings were performed: one during an on-going university examination, assumed as a real-life stressor, and one after holidays. Nonlinear analysis of HRV was performed by using Poincaré Plot, Approximate Entropy, Correlation dimension, Detrended Fluctuation Analysis, Recurrence Plot. For statistical comparison, we adopted the Wilcoxon Signed Rank test and for development of a classifier we adopted the Linear Discriminant Analysis (LDA). Results Almost all HRV features measuring heart rate complexity were significantly decreased in the stress session. LDA generated a simple classifier based on the two Poincaré Plot parameters and Approximate Entropy, which enables stress detection with a total classification accuracy, a sensitivity and a specificity rate of 90%, 86%, and 95% respectively. Conclusions The results of the current study suggest that nonlinear HRV analysis using short term ECG recording could be effective in automatically detecting real-life stress condition, such as a university examination.

    Understanding of standardized uptake value (SUV) of 2-deoxy-2-[18F]fluoro-d-glucose positron emission tomography (FDG-PET) depends on the background accumulations of glucose because the SUV often varies the status of patients. The purpose of this study was to develop a new method for quantitative analysis of SUV of FDG-PET scan images. The method included an anatomical standardization and a statistical comparison with normal cases by using Z-score that are often used in SPM or 3D-SSP approach for brain function analysis. Our scheme consisted of two approaches, which included the construction of a normal model and the determination of the SUV scores as Z-score index for measuring the abnormality of an FDG-PET scan image. To construct the normal torso model, all of the normal images were registered into one shape, which indicated the normal range of SUV at all voxels. The image deformation process consisted of a whole body rigid registration of shoulder to bladder region and liver registration and a non-linear registration of body surface by using the thin-plate spline technique. In order to validate usefulness of our method, we segment suspicious regions on FDG-PET images manually, and obtained the Z-scores of the regions based on the corresponding voxels that stores the mean and the standard deviations from the normal model. We collected 243 (143 males and 100 females) normal cases to construct the normal model. We also extracted 432 abnormal spots from 63 abnormal cases (73 cancer lesions) to validate the Z-scores. The Z-scores of 417 out of 432 abnormal spots were higher than 2.0, which statistically indicated the severity of the spots. In conclusions, the Z-scores obtained by our computerized scheme with anatomical standardization of torso region would be useful for visualization and detection of subtle lesions on FDG-PET scan images even when the SUV may not clearly show an abnormality.

  12. Examining Patient Conceptions: A Case of Metastatic Breast Cancer in an African American Male to Female Transgender Patient

    PubMed Central

    2009-01-01

    An African American male to female transgender patient treated with estrogen detected a breast lump that was confirmed by her primary care provider. The patient refused mammography and 14 months later she was diagnosed with metastatic breast cancer with spinal cord compression. We used ethnographic interviews and observations to elicit the patient’s conceptions of her illness and actions. The patient identified herself as biologically male and socially female; she thought that the former protected her against breast cancer; she had fears that excision would make a breast tumor spread; and she believed injectable estrogens were less likely than oral estrogens to cause cancer. Analysis suggests dissociation between the patient’s social and biological identities, fear and fatalism around cancer screening, and legitimization of injectable hormones. This case emphasizes the importance of eliciting and interpreting a patient’s conceptions of health and illness when discordant understandings develop between patient and physician. PMID:19898907

    1993-01-01

    Recently, Sassen provided evidence for supercooled water droplets in cirrus uncinus cell heads at temperatures between 40 and -50 C. Chemistry related to volcanic aerosol of stratospheric origin was evoked as an explanation for this phenomenon. Sassen speculated that injections of sulfuric acid droplets into the upper troposphere were accomplished by tropopause folds associated with subtropical jet streams. He also postulated global climatic perturbations due to the effect of these cirrus microphysical perturbations on radiative fluxes. Using data processing and objective analysis techniques described by Mace and Ackerman, the synoptic scale environment was examined for evidence of tropopause folds that may have served as a source mechanism of stratospheric aerosol in the upper troposphere.

    2014-07-01

    This study used experimental functional analyses to examine the operant function of challenging behaviors exhibited by 12 males (ages 27-51 months) with fragile X syndrome (FXS). Eight children met criteria for negatively reinforced challenging behavior in the form of escape from demands and/or escape from social interactions. Nine children met criteria for positively reinforced challenging behavior in the form of obtaining access to highly preferred items. Attention was identified as a maintaining consequence for three children. The functional analysis was inconclusive for one child. Results suggest that, for young males with FXS, challenging behaviors may more likely be tangibly and escape maintained than attention maintained. Our findings affirm past research suggesting a unique behavioral phenotype for this population.

  15. Combined examination of sequence and copy number variations in human deafness genes improves diagnosis for cases of genetic deafness

    PubMed Central

    2014-01-01

    Background Copy number variations (CNVs) are the major type of structural variation in the human genome, and are more common than DNA sequence variations in populations. CNVs are important factors for human genetic and phenotypic diversity. Many CNVs have been associated with either resistance to diseases or identified as the cause of diseases. Currently little is known about the role of CNVs in causing deafness. CNVs are currently not analyzed by conventional genetic analysis methods to study deafness. Here we detected both DNA sequence variations and CNVs affecting 80 genes known to be required for normal hearing. Methods Coding regions of the deafness genes were captured by a hybridization-based method and processed through the standard next-generation sequencing (NGS) protocol using the Illumina platform. Samples hybridized together in the same reaction were analyzed to obtain CNVs. A read depth based method was used to measure CNVs at the resolution of a single exon. Results were validated by the quantitative PCR (qPCR) based method. Results Among 79 sporadic cases clinically diagnosed with sensorineural hearing loss, we identified previously-reported disease-causing sequence mutations in 16 cases. In addition, we identified a total of 97 CNVs (72 CNV gains and 25 CNV losses) in 27 deafness genes. The CNVs included homozygous deletions which may directly give rise to deleterious effects on protein functions known to be essential for hearing, as well as heterozygous deletions and CNV gains compounded with sequence mutations in deafness genes that could potentially harm gene functions. Conclusions We studied how CNVs in known deafness genes may result in deafness. Data provided here served as a basis to explain how CNVs disrupt normal functions of deafness genes. These results may significantly expand our understanding about how various types of genetic mutations cause deafness in humans. PMID:25342930

    Hereditary neuropathy with liability to pressure palsy (HNPP) is an autosomal dominant disorder characterized by recurrent mono-neuropathies secondary to minor trauma or compression. Whilst typical episodes of palsy generally become apparent during the second and the third decades, HNPP is rarely diagnosed in the first decade. We present the case of a 6-year-old patient to draw attention to the possibility of HNPP attacks in the first decade and the importance of detailed electrophysiological examination.

    2010-01-01

    OBJECTIVE: 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. METHODS: 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. RESULTS: 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 articles were then briefly summarized. PMID:20835560

    A general survey of the main brazilian oil shale formations presenting their location, oil reserve, age and stratigraphy introduces this paper. It is followed by a comparative survey of the data on chemical composition (elementary, minerals and organic constituents/biological markers) and of thermal alteration indexes in order to define their maturity. The geochemical phenomena involved with a large diabase intrusion in the Irati formation is particularly stressed. The analytical methods of Solid Phase Extraction and Functional Group Marker developed for the analysis of bitumens and kerogens and the results obtained from the application of these methods to brazilian oil shales are discussed. The paper ends with a brief description of a comprehensive analytical bibliography on brazilian oil shales prepared to serve as a data base for these organites.

    2010-10-01

    Materials from our first autopsied case of diffuse Lewy body disease (DLBD), that was originally reported in 1976, were re-examined using recent immunohistochemical methods. Lewy pathology consisting of Lewy bodies and Lewy neurites appeared much more marked with alpha-synuclein immunostaining than had been detected with classical stainings. This case and our other similar cases prompted us to propose the terms "Lewy body disease" in 1980 and "diffuse Lewy body disease" in 1984. We also reported in 1990 that DLBD was classified into two forms: a pure form and a common form. Based on these studies the term "dementia with Lewy bodies (DLB)" was proposed in 1996. Since 1980, we have insisted that DLB, Parkinson disease (PD), and PD with dementia (PDD) should be understood within the spectrum of Lewy body disease. This insistence has been recently accepted by the International Workshop and the International Working Group on DLB and PDD in 2005 and in 2006, respectively.

    This study focused on how physics teachers develop and implement activities that promote creative thinking strategies in the standards based physics classroom. A particular focus was placed on every day or little "c", creativity, which can be taught in the high school classroom. The study utilized a multiple case study design, which allows for in-depth study in a variety of settings. Four participants from various high schools were identified utilizing administrator recommendations. Data were then collected via interviews, observations, and documents. The data were coded and analyzed for emerging themes. The themes were then merged to determine findings to the stated research questions. The research demonstrated the importance of modifying activities for student interest and understanding through effective use of scientific inquiry. The past experiences and professional development of the participants served as a vital piece to the development of their educational pedagogy especially concerning inquiry and questioning strategies. It was also established that an unstructured, positive classroom environment is a vital aspect of teaching while supporting creative thinking skills.

    Adverse outcome pathways (AOPs) offer a pathway-based toxicological framework to support hazard assessment and regulatory decision-making. However, little has been discussed about the scientific confidence needed, or how complete a pathway should be, before use in a specific regulatory application. Here we review four case studies to explore the degree of scientific confidence and extent of completeness (in terms of causal events) that is required for an AOP to be useful for a specific purpose in a regulatory application: (i) Membrane disruption (Narcosis) leading to respiratory failure (low confidence), (ii) Hepatocellular proliferation leading to cancer (partial pathway, moderate confidence), (iii) Covalent binding to proteins leading to skin sensitization (high confidence), and (iv) Aromatase inhibition leading to reproductive dysfunction in fish (high confidence). Partially complete AOPs with unknown molecular initiating events, such as 'Hepatocellular proliferation leading to cancer', were found to be valuable. We demonstrate that scientific confidence in these pathways can be increased though the use of unconventional information (eg, computational identification of potential initiators). AOPs at all levels of confidence can contribute to specific uses. A significant statistical or quantitative relationship between events and/or the adverse outcome relationships is a common characteristic of AOPs, both incomplete and complete, that have specific regulatory uses. For AOPs to be useful in a regulatory context they must be at least as useful as the tools that regulators currently possess, or the techniques currently employed by regulators.

    Sucrose solution is recommended as relevant pain relief management in neonates during acute painful procedures; however, only a few studies have analyzed the potentially adverse effects of sucrose administration to preterm neonates. The goal of this study was to examine the potential side effects of sucrose for pain relief in preterm infants, assessing feeding and weight gain during hospitalization and their feeding patterns postdischarge. The study sample consisted of 43 preterm neonates divided into two groups: a sucrose group (SG, n=18) and a control group (CG, n=25) in which no sucrose was administered. The SG received 0.5 mL/kg 25% oral sucrose for 2 min prior to all acute painful procedures during three consecutive days. A prospective review of medical charts was performed for all samples. The study was done prior to implementation of the institutional sucrose guidelines as a routine service, and followed all ethical requirements. There were no statistically significant differences between groups in terms of weight gain, length of stay with orogastric tubes, and parenteral feeding. Postdischarge, infant nutritional intake included feeding human milk to 67% of the SG and 74% of the CG. There were no statistically significant differences between groups regarding human milk feeding patterns postdischarge. Neonate feeding patterns and weight gain were unaffected following the short-term use of sucrose for pain relief. PMID:24820067

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

    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.

    Beryllium is widely distributed in soils at low levels, but it can also occur naturally in higher concentrations in a variety of materials exploited for many industrial applications. Beryllium is also one of the most toxic natural elements and is known to be a human carcinogen. A concise account of the literature data on baseline concentrations of Be in soils illustrates the possibility of worldwide presence of areas with a high natural background concentration of Be (up to 300 mg/kg), the crustal abundance of which is generally estimated to be in the range 2-6 mg/kg. Nevertheless, the number of available data is rather limited in comparison with those about other toxic elements such as Pb, Cd and Cr. This has probably caused the choice of low values of concentration level as the reference for the definition of soil contamination: these values are not always realistic and are not applicable to large areas. As a case study, we report and analyse a diffuse, unusually high (up to 80 mg/kg, average approximately 20 mg/kg), natural occurrence of beryllium in loose and poorly consolidated pyroclastic layers related to the Pleistocene activity of the Vico volcano. Additionally, the analysis of Be leachability has been carried out, providing evidence of a not negligible mobility in contrast with the scarce data presented in the literature that usually indicate beryllium as an element with low mobility in oxidising surface environmental conditions. This research marks the beginning of a possible reappraisal of beryllium geochemical behaviour and background levels, providing more realistic reference values for risk assessment and land management.

  5. Examining the interrelationship between DOC, bromide and chlorine dose on DBP formation in drinking water--a case study.

    During drinking water treatment aqueous chlorine and bromine compete to react with natural organic matter (NOM). Among the products of these reactions are potentially harmful halogenated disinfection by-products, notably four trihalomethanes (THM4) and nine haloacetic acids (HAAs). Previous research has concentrated on the role of bromide in chlorination reactions under conditions of a given NOM type and/or concentration. In this study different concentrations of dissolved organic carbon (DOC) from U.K. lowland water were reacted with varying amounts of bromide and chlorine in order to examine the interrelationship between the three reactants in the formation of THM4, dihaloacetic acids (DHAAs) and trihaloacetic acids (THAAs). Results showed that, in general, molar yields of THM4 increased with DOC, bromide and chlorine concentrations, although yields did fluctuate versus chlorine dose. In contrast both DHAA and THAA yields were mainly independent of changes in bromide and chlorine dose at low DOC (1 mg·L(-1)), but increased with chlorine dose at higher DOC concentrations (4 mg·L(-1)). Bromine substitution factors reached maxima of 0.80, 0.67 and 0.65 for the THM4, DHAAs and THAAs, respectively, at the highest bromide/chlorine ratio studied. These results suggest that THM4 formation kinetics depend on both oxidation and halogenation steps, whereas for DHAAs and THAAs oxidation steps are more important. Furthermore, they indicate that high bromide waters may prove more problematic for water utilities with respect to THM4 formation than for THAAs or DHAAs. While mass concentrations of all three groups increased in response to increased bromide incorporation, only the THMs also showed an increase in molar yield. Overall, the formation behaviour of DHAA and THAA was more similar than that of THM4 and THAA.

    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.

    This article describes a non-destructive analytical method developed to solve forensic document examination problems involving crossed lines and obliteration. Different strategies combining confocal Raman imaging and multivariate curve resolution-alternating least squares (MCR-ALS) are presented. Multilayer images were acquired at subsequent depth layers into the samples. It is the first time that MCR-ALS is applied to multilayer images for forensic purposes. In this context, this method provides a single set of pure spectral ink signatures and related distribution maps for all layers examined from the sole information in the raw measurement. Four cases were investigated, namely, two concerning crossed lines with different degrees of ink similarity and two related to obliteration, where previous or no knowledge about the identity of the obliterated ink was available. In the crossing line scenario, MCR-ALS analysis revealed the ink nature and the chronological order in which strokes were drawn. For obliteration cases, results making active use of information about the identity of the obliterated ink in the chemometric analysis were of similar quality as those where the identity of the obliterated ink was unknown. In all obliteration scenarios, the identity of inks and the obliterated text were satisfactorily recovered. The analytical methodology proposed is of general use for analytical forensic document examination problems, and considers different degrees of complexity and prior available information. Besides, the strategies of data analysis proposed can be applicable to any other kind of problem in which multilayer Raman images from multicomponent systems have to be interpreted.

    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.

    2010-01-01

    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.

    This comparative study uses data collected in 1990 and 1991 to examine the remittance behavior of Brazilians who had recently arrived in Canada and the United States. These data permit an examination of remittance activity among immigrants relatively soon after their arrival in a pair of host destinations. Prior to contrasting the remittance activity of these newly arrived immigrants, we first document the high degree of similarity between the two groups at their time of arrival; a point that becomes important when contrasting their divergent outcomes. Next, this study contributes to the research literature on micro-level remittance patterns and behaviors by focusing on three policy relevant dependant variables. More specifically, multivariate analyses are undertaken to examine those individual-level factors that best determine: (1) who remits, (2) how much they remit, and (3) when funds are remitted for productive purposes. Because the data analyzed were collected with the same instrument, results are then contrasted for the two destinations.One major finding to emerge from this cross-national study was that even immigrants who are extremely similar on all socio-economic measures at time of arrival may soon manifest divergent outcomes due to their distinctive country of destination experiences. Consequently, although some common predictors were found in both locales, there were far fewer than expected. For example, family obligation variables were usually significant in the predicted directions for the United States data, while this was almost never the case for the Canadian data. Furthermore, some variables often assumed to predict remittance behavior were insignificant in both locations. This study concludes by considering possible explanations for these results, as well as discussing the need for additional theoretical work and data collection in the area of immigrant remittance activity.

    Background 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. Objective This study sought to verify how frequently national papers are cited in the references of three Brazilian physical therapy journals. Method 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. Results 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. Conclusion 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. PMID:24675917

    There is a large spectrum of tumors presenting as nodular lesions that may affect the subungual space. We report the case of a 62-year-old woman presenting with a rapidly growing nodular lesion under the nail of the first left toe. Non-invasive examinations using dermoscopy, ultrasonography and elastography were performed for the preoperative assessment of the lesion. The biopsy of the lesion revealed superficial acral fibromyxoma, a benign tumor with predisposition for acral sites. The patient underwent radical surgery with wide resection margins. This is the first case report of a superficial acral fibromyxoma affecting the subungual region characterized by dermoscopic, ultrasonographic and elastographic features. We also performed a short review of the literature.

    Amelogenesis imperfecta (AI) is an overarching term for a group of rare inherited disorders of hard tooth tissues. It is characterized by various defects in proper enamel formation. AI is a severe disorder that affects both the aesthetics and function of the dentition, with affected teeth increasingly suffering from dental caries. Therefore, early diagnosis and lifelong stomatological interventions are important. Due to the complex nature of AI family history, stomatological, radiographic, and molecular genetic examinations should be part of the diagnostic portfolio. Additionally, we utilized new visualization methods for the assessment of teeth demineralization. We present a case report of two affected Czech sisters (6 and 8 years old) with clinically defined AI. These are the first Czech cases in which comprehensive clinical and genetic analysis had been carried out and reflect the complex clinical nature, positive treatment options, and limitations of candidate-gene molecular genetic testing.

    Brazil's experience in the use of ethyl alcohol, produced from sugar cane, as a motor fuel in the pure form or in the form of a 20 percent additive to gasoline, is examined. The production of ethanol was 4.2 billion liters from 1981 to 1982 and the plan calls for the production of 5.2 billion liters between 1982 and 1983. The total number of motor vehicles in Brazil which operate on pure alcohol reached 900,000 by the end of 1983 and the expenditure of alcohol in them reached 3 billion liters. The expansion of the use of ethanol as a motor fuel must substantially reduce Brazilian expenditures on the import of oil products, improve the use of agricultural resources and increase the labor force in agriculture. An analogous experience is justified for the U.S.A., but sugar beets must serve as the raw material for the production of ethanol in their case.

    Multiple endocrine neoplasia type 2 (MEN2) is a rare autosomal dominant monogenic disorder caused mostly by missense mutations in the RET (REarranged during Transfection) proto-oncogene on chromosome 10q11.2. MEN2A represents more than 50% of all MEN2 cases, having a regular pattern with medullary thyroid carcinoma (MTC) incidence of 90-100%, bilateral pheochromocytoma (PCC) incidence of 40-50% and primary hyperparathyroidism (HPT) incidence of 10-25%. Until recently, the diagnosis of MTC was most frequently based on fine-needle aspiration of thyroid nodules, after an ultrasound examination and endocrine evaluation of serum calcitonin levels. Nowadays, RET gene screening (starting with exons 10 and 11) is a mandatory test used for identification of both symptomatic and non-symptomatic MTC carriers or for exclusion of healthy individuals from subsequent periodical clinical/biochemical screening. In this context, and in the idea of PCC preceding MTC, the early detection of germline RET mutations are highly suggestive for hereditary disease. PCC diagnosis is established in classical manner by abdominal ultrasound imaging or computed tomography confirming the presence of adrenal gland masses, elevated plasma metanephrines and normetanephrines values and histopathological examination. Additional HPT diagnosis is acknowledged by serum ionized calcium and parathormone levels. Here we report a hereditary case of MEN2A in a two-generation Romanian family, along with data presenting the importance of correlative plurifactorial diagnostic scheme in this syndrome and a short literature review.

    Excessive demands on maternal nutritional status may be a risk factor for poor birth outcomes. This study examined the association between breastfeeding during late pregnancy (≥ 28 weeks) and the risk of having a small-for-gestational-age (SGA) newborn, using a matched case-control design (78 SGA cases: birthweight <10th percentile for gestational age; 150 non-SGA controls: 50th percentile cases and matched controls based on hospital, gestational age, and inter-gestational period. Mothers were interviewed and clinical chart extractions were completed. Factors associated with risk of SGA were assessed by their adjusted odds ratios (aOR) from conditional logistic regression. Exposure to an overlap of breastfeeding during late pregnancy was not associated with an increased risk of having a SGA newborn [aOR=0.58, 95% confidence interval (CI): 0.10-3.30]. However, increased risk was associated with having a previous low-birthweight birth (aOR=6.53; 95% CI: 1.43-29.70) and a low intake of animal source foods (<25th percentile; aOR=2.26; 95% CI: 1.01-5.04), and tended to be associated with being short (<150 cm; aOR=2.05; 95% CI: 0.92-4.54). This study found no evidence to support the hypothesis that breastfeeding during late pregnancy increases the risk for SGA; however, studies with greater statistical power are needed to definitively examine this possible association and clarify whether there are other risks to the new baby, the toddler and the pregnant woman.

    Previous work suggests that Brazilian Plasmodium falciparum has limited genetic diversity and a history of bottlenecks, multiple reintroductions due to human migration, and clonal expansions. We hypothesized that Brazilian P. falciparum would exhibit clonal structure. We examined isolates collected across two decades from Amapá, Rondônia, and Pará state (n = 190). By examining more microsatellites markers on more chromosomes than previous studies, we hoped to define the extent of low diversity, linkage disequilibrium, bottlenecks, population structure, and parasite migration within Brazil. We used retrospective genotyping of samples from the 1980s and 1990s to explore the population genetics of SP resistant dhfr and dhps alleles. We tested an existing hypothesis that the triple mutant dhfr mutations 50R/51I/108N and 51I/108N/164L developed in southern Amazon from a single origin of common or similar parasites. We found that Brazilian P. falciparum had limited genetic diversity and isolation by distance was rejected, which suggests it underwent bottlenecks followed by migration between sites. Unlike Peru, there appeared to be gene flow across the Brazilian Amazon basin. We were unable to divide parasite populations by clonal lineages and pairwise FST were common. Most parasite diversity was found within sites in the Brazilian Amazon, according to AMOVA. Our results challenge the hypothesis that triple mutant alleles arose from a single lineage in the Southern Amazon. SP resistance, at both the double and triple mutant stages, developed twice and potentially in different regions of the Brazilian Amazon. We would have required samples from before the 1980s to describe how SP resistance spread across the basin or describe the complex internal migration of Brazilian parasites after the colonization efforts of past decades. The Brazilian Amazon basin may have sufficient internal migration for drug resistance reported in any particular region to rapidly spread to

    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.

    Introduction Serotonin is a key neurotransmitter in the central nervous system. It has been suggested that serotoninergic dysfunction mediates the pathophysiology of temporomandibular dysfunction (TMD). Polymorphisms in the serotonin receptor gene (HTR2A) can alter its transcription, affecting the number of receptors in the serotoninergic system, altering nociceptive pain and hyperalgesia in TMD. The aim of this study is to investigate the association of the 102T-C polymorphism in the HTR2A gene in Brazilian patients with TMD. Material and methods This cross-sectional study examined 100 patients, of both genders, with TMD as index cases and 100 healthy volunteers as controls, also of both genders. DNA was extracted from peripheral blood leukocytes, and the site that encompassed the polymorphism in the HTR2A gene was amplified by polymerase chain reaction followed by restriction fragment length polymorphism (PCR-RFLP). Results Our results revealed that there were significantly more females among index cases compared with the control group (p < 0.05). The CC genotype of the 102T-C polymorphism was more frequent in patients with TMD vs. controls (OR: 2.25; 95% CI: 1.13–4.46; p < 0.05). Conclusions The present study supports the view that the 102T-C polymorphism in the HTR2A gene is associated with TMD in this studied Brazilian population. PMID:24482644

    Fenton's reaction is proposed as an accelerated weathering test for sulphides associated with Brazilian Coal Mining Residues (CMR), that are exposed to oxygen and water during the mining of coal. TEM and SEM/EDX were used to evaluate the nature, occurrence and distribution of minerals in remaining coals and other lithological units, before and after applying the test. Oxidation of CMRs was examined by analyzing soluble sulphur (sulphate) and dissolved metals by ICP-MS or ICP OES. As dissolved sulphate increases, dissolved Zn, Cd, Cu and Co concentrations increase, leading to undetectable amounts in the remaining solid phases; dissolved Ni and Mn also increase with the mobilized sulphur, but the remainder in the solids is the most important fraction; Fe and Pb are not mobilized due to precipitation as jarosite or hematite in the case of Fe or as sulphate in the case of Pb. Agreement between the observed results and the predictions by geochemical modelling is discussed.

    High rates of co-occurrence between substance abuse and child neglect have been well documented and especially difficult to treat. As a first step in developing a comprehensive evidence-based treatment for use in this population, the present case examination underscores Family Behavior Therapy (FBT) in the treatment of a mother who evidenced Substance Dependence, child neglect, Post-Traumatic Stress Disorder, Bipolar I Disorder, and domestic violence. Utilizing psychometrically validated self-report inventories and objective urinalysis, treatment was found to result in the cessation of substance use, lower risk of child maltreatment, improved parenting attitudes and practices, and reduced instances of violence in the home. The importance of utilizing validity scales in the assessment of referrals from child welfare settings is discussed, and future directions are reported in light of the results. PMID:23457426

    Few studies have examined the relationship between heart rate and self-injurious behavior (SIB) shown by individuals with IDD (intellectual and developmental disabilities). In this single-case study, we simultaneously monitored heart rate and activity levels during a functional analysis of severe skin picking behavior exhibited by a young man with Prader-Willi syndrome (PWS). Results of the functional analysis indicated that the participant's skin picking was maintained by automatic reinforcement. A within-session analysis of the data indicated that skin picking bouts resulted in an increase in heart rate, suggesting a positive- automatic reinforcement function. These data indicate that inclusion of heart rate and activity-level monitoring during a functional analysis may provide important additional information concerning the determinants of SIB.

    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. This is the first polyphasic study of cultured cyanobacteria from Brazilian mangrove ecosystems using morphological, genetic and biological approaches.

  11. PERSPECTIVE: Learning from the Brazilian biofuel experience

    Wang, Michael

    2006-11-01

    In the article `The ethanol program in Brazil' [1] José Goldemberg summarizes the key features of Brazil's sugarcane ethanol program—the most successful biofuel program in the world so far. In fact, as of 2005, Brazil was the world's largest producer of fuel ethanol. In addition to providing 40% of its gasoline market with ethanol, Brazil exports a significant amount of ethanol to Europe, Japan, and the United States. The success of the program is attributed to a variety of factors, including supportive governmental policies and favorable natural conditions (such as a tropical climate with abundant rainfall and high temperatures). As the article points out, in the early stages of the Brazilian ethanol program, the Brazilian government provided loans to sugarcane growers and ethanol producers (in most cases, they are the same people) to encourage sugarcane and ethanol production. Thereafter, ethanol prices were regulated to ensure that producers can economically sustain production and consumers can benefit from using ethanol. Over time, Brazil was able to achieve a price for ethanol that is lower than that for gasoline, on the basis of energy content. This lower cost is largely driving the widespread use of ethanol instead of gasoline by consumers in Brazil. In the United States, if owners of E85 flexible-fuel vehicles (FFVs) are expected to use E85 instead of gasoline in their FFVs, E85 will have to be priced competitively against gasoline on an energy-content basis. Compared with corn-based or sugar beet-based ethanol, Brazil's sugarcane-based ethanol yields considerably more favorable results in terms of energy balance and reductions in greenhouse gas emissions. These results are primarily due to (i) the dramatic increase of sugarcane yield in Brazil in the past 25 years and (ii) the use of bagasse instead of fossil fuels in ethanol plants to provide the heat needed for ethanol plant operations and to generate electricity for export to electric grids

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

    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.

    Pfeiffer syndrome (PS) is mainly characterized by craniosysnostosis, midface hypoplasia, great toes with partial syndactyly of the digits, broad and medially deviated thumbs. It is caused by allelic mutations in the fibroblast growth factor receptor 1 and 2 (FGFR1 and 2) genes. This study describes the clinical and genetic features of five Brazilian families affected by PS. All patients exhibited the classical phenotypes related to PS. The genetic analysis was able to detect the mutations Cys278Phe, Cys342Arg, and Val359Leu in three of these families. Two mutations were de novo, with one familial. We identified pathogenic mutations in four PS cases in five Brazilian families by PCR sequencing of FGFR1 exon 5 and FGFR2 exons 5, 8, 10, 11, 15, and 16. The clinical and genetic aspects of these families confirm that this syndrome can be clinically variable, with different mutations in the FGFR2 responsible for PS.

    This study describes how occupational health data have been gathered by the Brazilian Unified Health System (SUS) to provide morbidity and mortality estimates for formal and informal workers. In 2007, data on work-related diseases and injuries was incorporated into the compulsory notification system (SINAN) and analyzed by the SUS occupational health service network, which covers all Brazilian states. However, this work has not been fully implemented, resulting in the large-scale undercounting and underreporting of cases, particularly in relation to informal workers. This is suggestive of barriers that prevent access to services and good quality health care. The inclusion of work-related diseases and injuries in SINANs appears to be a feasible strategy for the collection of useful data for the surveillance of the entire universe of workers, particularly in countries where informal workers prevail within the labor force. Attention needs to be paid to the disparities in access and quality that affect low-paid, informal workers.

    2010-01-01

    Background Supportive neighbourhood walking conditions are particularly important for older people as they age and who, as a group, prefer walking as a form of physical activity. Urban form and socio-economic status (SES) can influence neighbourhood walking behaviour. The objectives of this study were: a) to examine how urban form and neighbourhood SES inter-relate to affect the experiences of older people who walk in their neighbourhoods; b) to examine differences among neighbourhood stakeholder key informant perspectives on socio-political processes that shape the walkability of neighbourhood environments. Methods An embedded comparative case study examined differences among four Ottawa neighbourhoods that were purposefully selected to provide contrasts on urban form (inner-urban versus suburban) and SES (higher versus lower). Qualitative data collected from 75 older walkers and 19 neighbourhood key informants, as well as quantitative indicators were compared on the two axes of urban form and SES among the four neighbourhoods. Results and discussion Examining the inter-relationship of neighbourhood SES and urban form characteristics on older people's walking experiences indicated that urban form differences were accentuated positively in higher SES neighbourhoods and negatively in lower SES neighbourhoods. Older people in lower SES neighbourhoods were more affected by traffic hazards and more reliant on public transit compared to their higher SES counterparts. In higher SES neighbourhoods the disadvantages of traffic in the inner-urban neighbourhood and lack of commercial destinations in the suburban neighbourhood were partially offset by other factors including neighbourhood aesthetics. Key informant descriptions of the socio-political process highlighted how lower SES neighbourhoods may face greater challenges in creating walkable places. These differences pertained to the size of neighbourhood associations, relationships with political representatives

    Brazilian immigration to Massachusetts and other states in the US grew significantly in the last two decades. There is a lack of data about the working conditions and health and safety hazards faced by Brazilian immigrant workers. We surveyed over 500 workers in Eastern Massachusetts through a community-based participatory research project to explore occupational and immigration factors that may represent a risk to the health of Brazilian immigrant workers, who mostly work in the construction, housecleaning, and food services segments of the state labor force. Our pilot study suggests that Brazilian immigrant workers are exposed to chemical, ergonomic, physical, and psychosocial job hazards and have experienced a variety of health symptoms that may be associated with these work environment exposures. Since most Brazilian workers have not received proper training to recognize the hazards, there is an urgent need for the implementation of culturally adequate training programs and enforcement of safety and health regulations to prevent occupational injuries and fatalities.

    The notification of the Human Immunodeficiency Virus (HIV) in Brazilian children was first reported in 1984. Since that time more than 21 thousand children became infected. Approximately 99.6% of the children aged less than 13 years old are vertically infected. In this context, most of the children are abandoned after birth, or lose their relatives in a near future, growing with uncertain identification. The present study aims to estimate the dental age of Brazilian HIV patients in face of healthy patients paired by age and gender. The sample consisted of 160 panoramic radiographs of male (n: 80) and female (n: 80) patients aged between 4 and 15 years (mean age: 8.88 years), divided into HIV (n: 80) and control (n: 80) groups. The sample was analyzed by three trained examiners, using Willems' method, 2001. Intraclass Correlation Coefficient (ICC) was applied to test intra- and inter-examiner agreement, and Student paired t-test was used to determine the age association between HIV and control groups. Intra-examiner (ICC: from 0.993 to 0.997) and inter-examiner (ICC: from 0.991 to 0.995) agreement tests indicated high reproducibility of the method between the examiners (P<0.01). Willems' method revealed discrete statistical overestimation in HIV (2.86 months; P=0.019) and control (1.90 months; P=0.039) groups. However, stratified analysis by gender indicate that overestimation were only concentrated in male HIV (3.85 months; P=0.001) and control (2.86 months; P=0.022) patients. The significant statistical differences are not clinically relevant once only few months of discrepancy are detected applying Willems' method in a Brazilian HIV sample, making this method highly recommended for dental age estimation of both HIV and healthy children with unknown age.

    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.

    Borreliosis caused by Borrelia burgdorferi sensu lato is a cosmopolitan zoonosis studied worldwide; it is called Lyme disease in many countries of the Northern Hemisphere and Lyme-like or Baggio-Yoshinari Syndrome in Brazil. However, despite the increasing number of suspect cases, this disease is still neglected in Brazil by the medical and veterinary communities. Brazilian Lyme-like borreliosis likely involves capybaras as reservoirs and Amblyomma and Rhipicephalus ticks as vectors. Thus, domestic animals can serve as key carriers in pathogen dissemination. This zoonosis has been little studied in horses in Brazil. The first survey was performed in the state of Rio de Janeiro, and this Brazilian Borreliosis exhibits many differences from the disease widely described in the Northern Hemisphere. The etiological agent shows different morphological and genetic characteristics, the disease has a higher recurrence rate after treatment with antibiotics, and the pathogen stimulates intense symptoms such as a broader immune response in humans. Additionally, the Brazilian zoonosis is not transmitted by the Ixodes ricinus complex. With respect to clinical manifestations, Baggio-Yoshinari Syndrome has been reported to cause neurological, cardiac, ophthalmic, muscle, and joint alterations in humans. These symptoms can possibly occur in horses. Here, we present a current panel of studies involving the disease in humans and equines, particularly in Brazil.

    This article deals with intergovernmental relations in health within the 20 years of implantation of the Unified Health System (SUS), in the light of the historical course of Brazilian federalism and its implications to health. Initially, a theoretical-conceptual review was carried out on the topic of federalism, social welfare and federative coordination of health, considering the international debate and the historical analysis of the Brazilian case. Following, the article analyzes the federal performance in the intergovernmental coordination of national health policy during the period of implantation of SUS, based on a research about the role of the Brazilian Ministry of Health from 1990 to 2002, which involved documental analysis and interviews with federal officers and other players in national politics. It was observed that health policies registered, in the past 20 years, changes in five relevant aspects that characterize federalism: institutional arrangements and rules for decisions in the federal government; the set of players with territorial basis; legal arrangements to define responsibilities among government levels; intergovernmental tax arrangements; informal arrangements among governments - vertically and horizontally.

    Brazil is a country of continental dimensions with widespread regional and social inequalities. In this report, we examine the historical development and components of the Brazilian health system, focusing on the reform process during the past 40 years, including the creation of the Unified Health System. A defining characteristic of the contemporary health sector reform in Brazil is that it was driven by civil society rather than by governments, political parties, or international organisations. The advent of the Unified Health System increased access to health care for a substantial proportion of the Brazilian population, at a time when the system was becoming increasingly privatised. Much is still to be done if universal health care is to be achieved. Over the past 20 years, there have been other advances, including investments in human resources, science and technology, and primary care, and a substantial decentralisation process, widespread social participation, and growing public awareness of a right to health care. If the Brazilian health system is to overcome the challenges with which it is presently faced, strengthened political support is needed so that financing can be restructured and the roles of both the public and private sector can be redefined.

    Abstract Objective: 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. Methods: Cross-sectional study that used the analytical data from 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 mutiple analyzes were performed, described in odds ratios and 95% confidence interval (OR/95%CI). Results: 7280 preschoolers were included. Of these, 1520 (21.1%) had dental pain in the last 6 months. The chance of the occurrence of dental pain was higher among those who used dental services (1.51/1.02–2.23), with tooth decay (3.08/2.08–4.56), that self-perceveid the need for dental treatment (3.96/2.48–6.34), whose parents reported dissatisfaction by children with their teeth and mouth (1.47/1.04–2.10) and those who reported impact of oral problems on quality of life (5.76/3.90–8.49). Conclusions: 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.

    We examined DNA polymorphisms in the nonrecombining portion of the Y-chromosome to investigate the contribution of distinct patrilineages to the present-day white Brazilian population. Twelve unique-event polymorphisms were typed in 200 unrelated males from four geographical regions of Brazil and in 93 Portuguese males. In our Brazilian sample, the vast majority of Y-chromosomes proved to be of European origin. Indeed, there were no significant differences when the haplogroup frequencies in Brazil and Portugal were compared by means of an exact test of population differentiation. Y-chromosome typing was quite sensitive in the detection of regional immigration events. Distinct footprints of Italian immigration to southern Brazil, migration of Moroccan Jews to the Amazon region, and possible relics of the 17th-century Dutch invasion of northeast Brazil could be seen in the data. In sharp contrast with our mtDNA data in white Brazilians, which showed that > or =60% of the matrilineages were Amerindian or African, only 2.5% of the Y-chromosome lineages were from sub-Saharan Africa, and none were Amerindian. Together, these results configure a picture of strong directional mating between European males and Amerindian and African females, which agrees with the known history of the peopling of Brazil since 1500.

    A new technique has recently been developed for estimating the volume of maggot masses on deceased persons using post-mortem CT scans. This allows volume to be measured non-invasively and factored into maggot mass temperature calculations for both casework and research. Examination of admission scans also allows exploration of entomological evidence in anatomical areas not usually exposed by autopsy (e.g. nasal cavities and facial sinuses), and before autopsy disrupts the maggot distribution on a body. This paper expands on work already completed by providing the x-ray attenuation coefficient by way of Hounsfield unit (HU) values for various maggot species, maggot masses and human tissue adjacent to masses. Specifically, this study looked at the HU values for four forensically important blowfly larvae: Lucilia cuprina, L. sericata, Calliphora stygia and C. vicina. The Calliphora species had significantly lower HU values than the Lucilia species. This might be explained by histological analysis, which revealed a non-significant trend, suggesting that Calliphora maggots have a higher fat content than the Lucilia maggots. It is apparent that the variation in the x-ray attenuation coefficient usually precludes its use as a tool for delineating the maggot mass from human tissue and that morphology is the dominant method for delineating a mass. This paper also includes three case studies, which reveal different applications for interpreting entomological evidence using post-mortem CT scans.

    Objective Communication technologies, such as personal online health communities, are increasingly considered as a tool to realise patient empowerment. However, little is known about the actual use of online health communities. Here, we investigated if and how patients' use of online communities supports patient empowerment. Setting A network of primary and secondary care providers around individual patients with Parkinson's disease. Participants We conducted case studies to examine our research question. We interviewed 18 patients with Parkinson's disease and observed the use of online health communities of 14 of them for an average of 1 year. Primary outcome measures We analysed the interviews and the online conversations between patients and healthcare providers, using Foucault's framework for studying power processes. Results We observed that patient empowerment is inhibited by implicit norms that exist within these communities around the number and content of postings. First, patients refrained from asking too many questions of their healthcare providers, but felt obliged to offer them regular updates. Second, patients scrutinised the content of their postings, being afraid to come across as complainers. Third, patients were cautious in making knowledge claims about their disease. Conclusions Changing implicit norms within online communities and the societal context they exist in seems necessary to achieve greater patient empowerment. Possibilities for changing these norms might lie in open dialogue between patient and healthcare providers about expectations, revising the curriculum of medical education and redesigning personal online health communities to support two-way knowledge exchange.

    Federally funded scientific research is one of the building blocks of technological advancement and economic growth. This research can also lead to transformational ideas and discoveries. In our current fiscal environment, strategies to rein in federal spending have become a priority, although they have proven to be complex. The possible deals and negotiations to reduce federal spending may hinder the work of the scientific community to serve society. Since 2005 federal investment in research and development has slowed. The average annual growth in federal funding for scientific research from 2004 - 2009 was 0.9% as compared to 3.3% over the previous 20 years. What does the current budget situation mean for science? It means reductions in basic and applied research, interruptions in long-term monitoring and data collection, an inability to repair or build infrastructure, and less federal grant support for current and future scientists. I will first provide an update on the current federal budget situation and examples of how current policies are impacting the scientific community. Second, I will present a case study of the effect of reduced federal investment in science. Specifically, I will discuss how investments in research and development have far-reaching impacts on society and examine how reduced funding impairs valuable research efforts.

    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.

    Tuberculosis control measures in Brazil's prison population have been regulated for ten years under the National Prison Health System Plan. Brazilian states have different organizational models for the Tuberculosis Control Program (TCP) in their prison systems. This study evaluated TCP implementation in prisons in two Brazilian states, using a multiple case study design with a qualitative approach and a log-frame analysis and assessment. According to predefined criteria, two state cases were selected, with two analytical units for each case and one prison hospital in Case 2. We identified partial program implementation in the Case 1 prisons and prison hospital and low implementation in non-hospital prison health services in Case 2. Lack of financial investment and resources, lack of integration between the courts and law enforcement system and health institutions, and poor access to health services in prisons were adverse factors for program implementation.

    A recent published newspaper article commented on the (lack of) quality of Brazilian science and its (in) efficiency. The newspaper article was based on a special issue of Nature and on a new resource for scientometrics called Nature Index. I show here arguments and sources of bias that, under the light of the principle in dubio pro reo, it is questionable to dispute the quality and efficiency of the Brazilian science on these grounds, as it was commented on the referred article. A brief overview of Brazilian science is provided for readers to make their own judgment.

    Including students' perceptions in the educational process is considered a key component in monitoring the quality of academic programs. This study aimed to evaluate the concept of one's learning experience in endodontic teaching from the perspective of a group of Brazilian students. A total of 126 self-administered, structured questionnaires were distributed to undergraduate dental students enrolled in endodontics courses during the second semester of the 2009 academic year. The questionnaires were administered during final examinations and focused on students' opinions concerning learning during endodontic treatments, time spent during endodontic treatments, difficulties found during endodontic treatments, quality of endodontic treatments performed, characteristics of the technique employed, and suggestions to improve endodontic teaching. Ninety-one percent of the questionnaires were returned for evaluation. The obtained answers were discussed and analyzed, thereby generating quantitative and qualitative data showing students' perceptions of their experiences in endodontics courses. The main points that can affect the teaching of endodontics, according to the undergraduate students, included patients' absences and delays, selection of patients, preclinical and clinical training, difficulties found, type of technique employed, and teachers' orientation during endodontic treatment. The students' perceptions provided valuable information about the development of the course and the teacher-student relationship, together with the added intention of enhancing the teaching of endodontics as well as other courses.

    This study aimed to develop and validate a Brazilian version of the Food Craving Inventory (FCI-Br), adapted to the cultural-gastronomic context of Brazil, and to explore this behavior among adult Brazilians. The Study 1 population consisted of 453 adults from all regions of Brazil. Participants responded to a preliminary form of the instrument online. Exploratory factor analysis revealed an FCI-Br presenting 23 items and three factors: High Fat, Sweet Food and Traditional Meal. The FCI-Br overall reliability was considered adequate (α = 0.82), as were each of the sub-scales. The food items receiving higher average scores from the application of the instrument were chocolate (3.14 ± 1.28; women) and bread (2.94 ± 1.44, men). A significant association was observed between the specific-craving for Sweet Food and female respondents. Most participants reported experiencing more frequent episodes of food craving when alone (68.0%; n = 391) and during the afternoon (32.2%; n = 127) or evening (43.8%; n = 173) hours. Application of the FCI-Br in a population of 649 university students (Study 2) demonstrated a good adjustment of the model developed according to the Confirmatory factor analysis (χ(2)/gl = 2.82, CFI = 0.94; TLI = 0.93; RMSEA = 0.06). The current findings indicate that the FCI-Br has adequate psychometric properties to measure craving behavior with respect to specific food groups in the resident population of Brazil. The results of this study also shed light on the importance of considering the cultural diversity of a population when investigating eating behaviors.

    OBJECTIVE To describe the prevalence of asthma and physician-diagnosed asthma in Brazilian adolescents. METHODS Cross-sectional, national, school-based study with adolescents from 12 to 17 years old, participants in the Study of Cardiovascular Risks in Adolescents (ERICA). The study stratified the sample by region and grouped according to schools and classes with representativeness to the set of cities with more than 100,000 inhabitants of the Country, macro-regions, capitals, and Federal District. A questionnaire collected data through a self-filled in method. We calculated the prevalences and their confidence intervals of 95% (95%CI) according to sex, age group, type of school and skin color. RESULTS Between 2013 and 2014, 74,589 adolescents were evaluated, 55.3% of the female sex. The total prevalence of active asthma was of 13.1% (95%CI 12.1-13.9), being higher in girls (14.8%; 95%CI 13.7-16.0) when compared to boys (11.2%; 95%CI 10.3-12.2) in all geographical strata examined. It was also higher between students of private schools (15.9%; 95%CI 14.2-17.7) when compared to public ones (12.4%; 95%CI 11.4-13.4). It was higher in the Southeast region (14.5%; 95%CI 12.9-16.1), and in the city of Sao Paulo (16.7%; 95%CI 14.7-18.7). The lowest prevalence was observed in North region (9.7%; 95%CI 9.7-10.5), and in Teresina (6.3%; 95%CI 4.9-7.7). The prevalence of physician-diagnosed asthma was of 8.7% (95%CI 8.2-9.1); higher in the North region (13.5%; 95%CI 12.7-14.2), and in Porto Alegre (19.8%; 95%CI 17.5-22.3). It was lower in the Midwest (6.9%; 95%CI 6.0-7.8), and in Cuiaba (4.8%; 95%CI 3.8-5.9). We found no significant difference in the expression of this rate between the sexes, as well as in other variables evaluated by the study. CONCLUSIONS The prevalence of asthma in Brazilian adolescents is high. Rates of active asthma and physician-diagnosed asthma vary widely in different regions and capitals evaluated by the ERICA.

    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.

    Signicant progress has been obtained since the Second Brazilian Consensus Conference on Helicobacter pylori Infection held in 2004, in São Paulo, SP, Brazil, and justify a third meeting to establish updated guidelines on the current management of H. pylori infection. The Third Brazilian Consensus Conference on H pylori Infection was organized by the Brazilian Nucleus for the Study of Helicobacter, a Department of the Brazilian Federation of Gastroenterology and took place on April 12-15, 2011, in Bento Gonçalves, RS, Brazil. Thirty-one delegates coming from the five Brazilian regions and one international guest, including gastroenterologists, pathologists, epidemiologists, and pediatricians undertook the meeting. The participants were allocated in one of the five main topics of the meeting: H pylori, functional dyspepsia and diagnosis; H pylori and gastric cancer; H pylori and other associated disorders; H pylori treatment and retreatment; and, epidemiology of H pylori infection in Brazil. The results of each subgroup were submitted to a final consensus voting to all participants. Relevant data were presented, and the quality of evidence, strength of recommendation, and level of consensus were graded. Seventy per cent and more votes were considered as acceptance for the final statement. This article presents the main recommendations and conclusions to guide Brazilian doctors involved in the management of H pylori infection.

    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.

    The recent reduction in breast cancer mortality in high-income countries resulted from improvements in early detection and treatment. Breast cancer is the most common cancer in Brazilian women. Since 2004, the government has recommended annual clinical breast examination for women aged ≥ 40 years and biannual mammograms for those aged 50-69. This article investigates the degree of implementation of these guidelines using data from the Brazilian Unified National Health System for 2010 according to major geographic region and age group. The findings showed low national mammogram coverage in the target population (32% in the 50-59-year group; 25% from 60 to 69 years). The percentage of women with abnormal radiological findings who underwent biopsy was also low (27% for 50-59 years; 63% for 60-69 years). The number of breast cancer surgeries exceeded the number of cases detected by mammography but was well below the estimated number of incident breast cancer cases in 2010. There are striking regional inequalities in access to early detection and surgery, being the lowest access in the North Region and the highest in the South Region.

  12. Extractive reserves in Brazilian Amazonia

    SciTech Connect

    Fearnside, P.M )

    1989-06-01

    In 1985 an opportunity arose for maintaining tracts of Amazonian forest under sustainable use. Brazil's National Council of Rubber Tappers and the Rural Worker's Union proposed the creation of a set of reserves of a new type, called extractive reserves. The first six are being established in one of the Brazilian states most threatened by deforestatation. The creation of extractive reserves grants legal protection to forest land traditionally used by rubber tappers, Brazil-nut gatherers, and other extractivists. The term extrativismo (extractivism) in Brazil refers to removing nontimber forest products, such as latex, resins, and nuts, without felling the trees. Approximately 30 products are collected for commercial sale. Many more types of forest materials are gathered, for example as food and medicines, for the extractivists' own use. The reserve proposal is attractive for several reasons related to social problems. It allows the rubber tappers to continue their livelihood rather than be expelled by deforestation. However, it is unlikely that sufficient land will be set aside as extractive reserves to employ all the tappers. Displaced rubber tappers already swell the ranks of urban slum dwellers in Brazil's Amazonian cities, and they have become refugees to continue their profession in the forests of neighboring countries, such as Bolivia.

    A total of 2152 Actinobacteria strains were isolated from native Cerrado (Brazilian Savannah) soils located in Passos, Luminárias, and Arcos municipalities (Minas Gerais State, Brazil). The soils were characterised for chemical and microbiological analysis. The microbial analysis led to the identification of nine genera (Streptomyces, Arthrobacter, Rhodococcus, Amycolatopsis, Microbacterium, Frankia, Leifsonia, Nakamurella, and Kitasatospora) and 92 distinct species in both seasons studied (rainy and dry). The rainy season produced a high microbial population of all the aforementioned genera. The pH values of the soil samples from the Passos, Luminárias, and Arcos regions varied from 4.1 to 5.5. There were no significant differences in the concentrations of phosphorus, magnesium, and organic matter in the soils among the studied areas. Samples from the Arcos area contained large amounts of aluminium in the rainy season and both hydrogen and aluminium in the rainy and dry seasons. The Actinobacteria population seemed to be unaffected by the high levels of aluminium in the soil. Studies are being conducted to produce bioactive compounds from Actinobacteria fermentations on different substrates. The present data suggest that the number and diversity of Actinobacteria spp. in tropical soils represent a vast unexplored resource for the biotechnology of bioactives production. PMID:23555089

    Braga, Joao

    The Brazilian scientific balloon program is based almost entirely at the National Institute for Space Research -INPE, which has a facility for research and development of scientific balloon systems such as telemetry, command, power supply, separation and flight train devices, ballast control systems, ATC transponders, shock absorbers and especially different launching tech-niques. The Balloon Launching Center of INPE operates since the early 70s, when the first launches were performed in cooperation with French groups for astronomical gamma-ray obser-vations. Since then, the center was involved in a large numbers of international collaborations with France, Japan, United Kingdom, USA, Italy, Germany and Tasmania. INPEs high-energy astrophysics group developed several X and Gamma-ray experiments that were launched in balloons since the early 80s. The most complex of these payloads is the MASCO experiment, launched in 2004. It consists in a 2-ton experiment with a large gamma-ray imaging coded-mask telescope and an attitude control system developed at INPE. Currently, the high-energy group is developing a prototype balloon experiment for the MIRAX satellite, named protoMIRAX. Others scientists at INPE have also used balloons for cosmic rays, geophysics and atmospheric electricity experiments.

    1991-12-01

    This article contains a the script for a slide-tape presentation entitled Working Against AIDS, a presentation developed by the Brazil Family Planning Association (BEMFAM) which is designed to debunk common misconceptions about the disease. This audio-visual, which targets Brazilian workers, can be used during talks, seminars, and meetings. A discussion of the issues involved usually follows the presentation of Working Against AIDS. The presentation contains 30 illustrated slides (these are included in the article). The presentation begins by explaining that much of the information concerning AIDS is prejudicial and misleading. The next few slides point out some of the common misconceptions about AIDS, such as claims denying the existence of the disease, or suggestions that only homosexuals and prostitutes are at risk. The presentation then goes on to explain the ways in which the virus can and cannot be transmitted. Then it discusses how the virus destroys the body's natural defenses and explains the ensuing symptoms. Slides 14 and 15 point out that no cure yet exists for AIDS, making prevention essential. Slides 16-23 explain what actions are considered to be high risk and which ones do not entail risk. Noting that AIDS can be prevented, slide 24 says that the disease should not present an obstacle to spontaneous manifestations of human relations. The next slide explains that condoms should always be used when having sex with someone who could be infected with AIDS. Finally slides 26-30 demonstrate the proper way to use and dispose of a condom.

    In response to an alarming rise in human immunodeficiency virus (HIV) infection among Brazilian women during the early 1990s, the Sociedade Civil Bem-Estar Familiar no Brazil (BEMFAM) developed a project that integrates HIV prevention with clinical services, community-based prevention activities, and sexually transmitted disease diagnosis and treatment. Preliminary interviews with clinic clients revealed that women's fears they would be considered unfaithful were impeding their ability to suggest condom use to their sexual partners. Condom use within a relationship was considered appropriate only for pregnancy prevention. To facilitate dialogue about sexual health, BEMFAM developed a women's group intervention project. All women who attend a BEMFAM clinic are invited to participate in a one-hour group discussion before receiving medical services. Novela-style booklets with stories and characters women can relate to their own lives are used to stimulate discussion. Participants learn to use condoms correctly by putting them on a penis model and anticipate situations in which they would be able to negotiate condom use. The group setting enables women to gain confidence and practice assertiveness in a non-threatening, supportive environment. Their identification with other women's stories empowers women to take control of their health and sexual lives. Between October 1994 and July 1995, 3464 women participated in group discussions organized by BEMFAM and 40,688 condoms were distributed; 18% of these women returned to the clinic for additional condoms.

    Objective Our objectives were: to assess the QOL of Brazilian adolescents with epilepsy with a specific QOL assessment tool; to compare the adolescents with epilepsy and healthy adolescents using a generic QOL assessment tool; to correlate the 2 different QOL assessment tools (the generic and the epilepsy-specific); and to correlate QOL scores of the adolescents with epilepsy obtained by both tools with physical, psychological and social variables of the disease. Methods Fifty subjects (case group) attending the outpatient clinic of epilepsy of the Clinics Hospital of UNICAMP, Campinas-SP, answered the Brazilian version of the QOL inventory for adolescents with epilepsy - QOLIE-AD-48 and the QOL Questionnaire - WHOQOL – BREF – Portuguese version. Fifty-one subjects (control group) from public schools in Campinas-SP answered only the WHOQOL-BREF. Results The results showed that adolescents with epilepsy presented a good score of QOL in both tools; overall scores for both groups with WHOQOL-BREF were good, but a statistically significant difference was seen with regards to the Psychological domain of the WHOQOL-BREF favoring the control group. Significant correlations between QOLIE-AD-48 Total and WHOQOL domains were found. Adolescents that were considered seizure-free (P = 0.001), had good perception of seizure control (P = 0.012) and had not had occurrence of seizures in public places (P = 0.001) presented better QOL scores. Conclusions Brazilian adolescents with epilepsy may present good QOL scores when they themselves consider the disease as under control; physical, social and especially psychological variables associated to the disease may play an important role in these results. As a generic QOL tool, WHOQOL-BREF was sufficient to allow for a comparison between chronic disease bearers and healthy adolescents and showed that the gap in QOL between both populations is not as extensive as once was thought, probably due to better support and

  1. 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.

  2. A review of cardiopulmonary research in Brazilian medical journals: clinical, surgical and epidemiological data.

    2010-04-01

    Research in the field of cardiopulmonary disease in Brazil has been very active in recent decades. 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.

    1995-01-01

    General concern about increasing reports of emergencies caused by or attributed to the exposure of human beings to various toxic agents has created demand for assessing the informational performance of a Brazilian network of 34 poison control centers (PCCs), located in different regions of the country and pertaining to the National Poison Information System (SINITOX). The primary purpose of these PCCs is to inform the public, prevent cases of poisoning, and provide medical care. This paper analyzes the available resources for identifying cases of poisoning, preventing new occurrences, and monitoring the consequences of toxic agents. This paper also analyzes data recorded front 1990 to 1992. The objective is to identify the main constraints to using health-data and management information as decision-making tools at the local level.

    2012-09-01

    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.

    The present investigation examined the validity and reliability of a questionnaire which assessed motives of Brazilian adults for participation in physical activities, compared motives for participation in walking and fitness programs, and examined differences by sex, age, and education. Participants were 100 men and 138 women, ages 16 to 60 years (M=30.5, SD=11.4). Factor analysis identified four factors which were fairly consistent with previous research. Improvement in physical appearance and enjoyment were rated significantly more important reasons for participants in fitness programs than for walkers. Men were more motivated by social experience than women. Young adults rated importance lower in health and fitness and rated enjoyment, social experience, and improvement in appearance of higher importance. Health and fitness were considered more important by participants with more education. These results are consistent with previous research on the factors underlying motives for regular exercise and support the importance of considering differences associated with culture.

    2000-01-01

    Stringent exclusion criteria in drug abuse research are necessary to protect against methodological confounds compromising the interpretation of findings. However, reliance on self-report screening may fail to detect important exclusion variables. We compared three levels of exclusion criteria screening in a study of neurophysiological/neurocognitive sequelae of chronic marihuana use in normals. LEVEL 1 (self-report) consisted of telephone pre-screening. LEVEL 2 (also self-report) involved in-depth personal interviews. LEVEL 3 consisted of several direct examination assessments including a medical/psychiatric examination by a board certified psychiatrist, eight weeks of twice per week urine drug screens, an EEG exam and eight hours of neuropsychological testing. Results indicated that 39.0% of subjects passing self-report screening had significant exclusion criteria findings that were only detected through LEVEL 3 direct examination procedures. Of all subjects found to have exclusion criteria after being provisionally accepted following LEVEL 1 telephone pre-screening, 55.7% were detected only through more rigorous LEVEL 3 direct examination screening methods.

    2004-09-01

    The purpose of the present study was to translate and adapt the Berg balance scale, an instrument for functional balance assessment, to Brazilian-Portuguese and to determine the reliability of scores obtained with the Brazilian adaptation. Two persons proficient in English independently translated the original scale into Brazilian-Portuguese and a consensus version was generated. Two translators performed a back translation. Discrepancies were discussed and solved by a panel. Forty patients older than 65 years and 40 therapists were included in the cultural adaptation phase. If more than 15% of therapists or patients reported difficulty in understanding an item, that item was reformulated and reapplied. The final Brazilian version was then tested on 36 elderly patients (over age 65). The average age was 72 years. Reliability of the measure was assessed twice by one physical therapist (1-week interval between assessments) and once by one independent physical therapist. Descriptive analysis was used to characterize the patients. The intraclass correlation coefficient (ICC) and Pearson's correlation coefficient were computed to assess intra- and interobserver reliability. Six questions were modified during the translation stage and cultural adaptation phase. The ICC for intra- and interobserver reliability was 0.99 (P < 0.001) and 0.98 (P < 0.001), respectively. The Pearson correlation coefficient for intra- and interobserver reliability was 0.98 (P < 0.001) and 0.97 (P < 0.001), respectively. We conclude that the Brazilian version of the Berg balance scale is a reliable instrument to be used in balance assessment of elderly Brazilian patients.

    The Ministry of Health coordinates and orients in Brazil all the activities concerning the acquired immunodeficiency syndrome which is officially designated as AIDS. The first AIDS' case registered in Brazil was, by retrospective diagnosis, in 1981 but it was in 1982 that the first two diagnosis in live patients were made. The incidence is very high in this country that is among the ones where the higher number of cases are being registered. The great majority of the Brazilian cases occurs in the cities and in direct proportion to the population index. The groups of risk are the same universally known and a comparative increase of heterosexual transmission is noted, chiefly due to the use of injectable drugs and bisexuality of the male partners. Another problem that is being increased is pediatric AIDS, with raising importance of perinatal transmission as well as the use of injectable drugs and precocious prostitution in adolescence. The transfusional and haemophilic AIDS have proportionally decreased due to the control of blood products. The control and the orientation activity of the Ministry of Health is directed to varied points such as: compulsory cases notification, cooperation between public and private sectors, preventive and sexual orientation, freely delivered medication and laboratory tests including sigilous tests, lay and technical personnel preparation, diversified informative and educational campaigns. Trial tests with anti-HIV vaccines have begun to be performed. Multiple Reference Centers were officially established by the administration. Among them is to be quoted the Hospital Universitário Gaffrée Guinle of Rio de Janeiro where the authors work. It is credited for its intensive activity and pioneerism. In this Institution special attention was due against discrimination of HIV-infected patients, to diagnosis, to anonymous and sigilous tests, to medical and psychological assistance, to myocardium involvement, to the virologic study of the

    The aim of the study was to compare parents' experience of a routine ultrasound examination in the second trimester, when a choroid plexus cyst/cysts (CPC) were found (Study group; n = 22), with matched controls where no fetal deviations were identified (Control group, n = 66). All the parents had participated in a larger cohort study. The instruments used for measuring anxiety were STAI-state/trait, sense of coherence (SOC) and Parents' Expectations, Experiences, Reactions to an Ultrasound examination during pregnancy (PEER-U, State of Mind Index). Regarding the SOC and STAI-state/trait no significant differences were found between the cases and controls or within the respective group before and after the ultrasound examination. The cases had an increase in anxiety (more anxious) as measured by the instrument PEER-U after the examination, while the controls showed a significant better level of State of Mind Index (less anxious) after the examination, compared to before. Therefore PEER-U can be a more reliable instrument when studying state of mind (anxiety) in connection with ultrasound examinations, and as it is specific for this situation it does not appear to be time dependent.

    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.

  9. Economic and social characteristics of the Brazilian population.

    Sanders, T G

    1982-01-01

    The question of whether Brazilians have improved their economic situation since 1970 is controversial. A number of questions on the Brazilian census of 1980 dealt with the economic and social characteristics of the population. The usefulness of census data lies in their capacity to indicate trends every 10 years. Consequently, one can get some idea of whether Brazil is making progress in certain aspects of modernization or in improving the skills and living conditions of the people. Census data have limitations. They indicate averages, not specific cases. They fail to raise a number of questions about economic and social conditions that would improve understanding. Discussion is focused on population structure and the economy, income, housing, education, and health. Brazil is continuing the process of modernization by which population shifts from the primary sector (agriculture and mining) into other sectors of the economy. The 14.88% of the work force in agriculture, livestock, and fishing represent about 30% of the potentially economically active (PEA) population. 1/3 of the population is still rural, but the trend since 1940 is striking. The momentum of decline intensified in both 1960-70 and 1970-80, reflecting a process of abandoning small farms, mechanizing larger farms, and a general flow of population to the cities. All other sectors of the economy have increased the proportion of people working in them. The data of 1980 reflect a period of sustained economic growth that culminated in that year with an increase of 8%. In 1981 and 1982, Brazil had been in a recession so that in 1983 some of these figures might have changed. The dispute began when the results of the 1970 census were used to show that income was becoming more concentrated, i.e., the top percentages, in comparison with 1960, received a larger share of national income, while the lowest percentages received less. The differences in income between men and women is particularly strong in the

    2016-02-01

    Although the practice of physician-assisted dying (hereinafter "PAD") will soon be lawful in Canada, opponents of PAD claim that it might result in involuntary deaths. The Supreme Court of Canada in Carter v. Canada (Attorney General) rejected such arguments holding that involuntary deaths are preventable provided that jurisdictions devise stringent limits to the practice of PAD and that these stringent limits are "scrupulously monitored and enforced". This article examines the question of how best to engage in scrupulous monitoring of physician-assisted dying. At present, the province of Quebec has legislated, and three expert groups have proposed the creation of new administrative offices to monitor the practice of PAD (these groups are the Provincial-Territorial Expert Advisory Group on Physician-Assisted Dying, the External Panel on Options for a Legislative Response to Carter v. Canada, and the Canadian Medical Association). This article argues that scrupulous monitoring can be better achieved by requiring explicit mandatory notification of all physician-assisted deaths to coroners and medical examiners, rather than by creating new administrative offices. It is more effective, efficient and prudent to use already existing coroner and medical examiner death reporting and investigative frameworks to report physician-assisted deaths than to create new, untried, parallel and potentially more expensive administrative offices. In Canada, almost all provincial and territorial statutes that govern the official actions of coroners and medical examiners currently require the reporting of non-natural deaths, which include those that will be attributable to PAD. To achieve the scrupulous monitoring of PAD required by the Supreme Court, provincial and territorial governments, in collaboration with the federal government, should. 1. review their coroner and fatality statutes to clarify that physician-assisted deaths (as non-natural deaths) are mandatorily notifiable; 2

    2010-01-01

    This review examines what have been, to this point, generally two divergent lines of research: (a) effects of parental drug abuse on children, and (b) effects of children's exposure to interparental violence. A small, but growing body of literature has documented the robust relationship between drug use and intimate partner violence. Despite awareness of the interrelationship, little attention has been paid to the combined effect of these deleterious parent behaviors on children in these homes. Thus, we argue for the need to examine the developmental impact of these behaviors (both individually and combined) on children in these homes and for treatment development to reflect how each of these parent behaviors may affect children of substance abusers.

    Pfeiffer syndrome (PS) is mainly characterized by craniosysnostosis, midface hypoplasia, great toes with partial syndactyly of the digits and broad and medially deviated thumbs. It is caused by allelic mutations in the fibroblast growth factor receptor 1 and 2 (FGFR1 and 2) genes. This study describes the clinical and genetic features of five Brazilian families affected by PS. All patients exhibited the classical phenotypes related to PS. The genetic analysis was able to detect the mutations Cys278Phe, Cys342Arg, and Val359Leu in three of these families. Two mutations were de novo, with one familial. We identified pathogenic mutations in four PS cases in five Brazilian families by PCR sequencing of FGFR1 exon 5 and FGFR2 exons 5, 8, 10, 11, 15, and 16. The clinical and genetic aspects of these families confirm that this syndrome can be clinically variable, with different mutations in the FGFR2 responsible for PS. Key words:Craniosynostosis, Pfeiffer syndrome, mutation, FGFR2. PMID:25129254

The search was conducted through the MEDLINE and LILACS databases, selecting papers in which the term "multiple sclerosis" was defined as the main topic and "Brazil" or "Brasil" as others. The data were analyzed regarding the themes, the state in Brazil and institution where the papers were produced, the journals where the papers were published, journal's impact factor, and language. The search disclosed 141 documents (91 from MEDLINE and LILACS, and 50 from LILACS only) published in 44 different journals (23 of them MEDLINE-indexed). A total of 111 documents were produced by 17 public universities, 29 by 3 private medical schools and 1 by a non-governmental organization. There were 65 original contributions, 37 case reports, 20 reviews, 6 PhD dissertations, 5 guidelines, 2 validation studies, 2 clinical trials, 2 chapters in textbooks, 1 Master of Science thesis, and 1 patient education handout. The journal impact factor ranged from 0.0217 to 6.039 (median 3.03). Of 91 papers from MEDLINE, 65 were published by Arquivos de Neuro-Psiquiatria. More than 90% of the papers were written in Portuguese. São Paulo was the most productive state in the country, followed by Rio de Janeiro, Minas Gerais and Paraná. Eighty-two percent of the Brazilian output came from the Southeastern region.

    The current population of Japanese-Brazilians living in Japan consists mainly of second- and third-generation Japanese immigrants to Brazil. In the last 10 years, they have migrated to Japan, their ancestral country, mostly as industrial workers. The objective of this study was to examine possible relationships between mental disorders and both pre-migration psychosocial factors and acculturative status, among Japanese-Brazilians in Japan. We developed our own Portuguese acculturation-questionnaire to assess the their adaptation to Japanese society and their ethnic-cultural identity. Using the acculturation-questionnaire, the Portuguese version of the self-reporting questionnaire (SRQ-20) and an identification form with socio-demographic and clinical data, a community sample of 131 Japanese-Brazilian immigrants in Utsunomiya and outpatient sample of 32 Japanese-Brazilians in the psychiatric department of a medical school in the same region were compared. Analysis was done by chi 2 Fisher and multiple logistic regression. The socio-demographic data indicated that the outpatients were most likely to have past medical history (OR = 12.3), traumatic experience (OR = 10.1) in Brazil before immigration, short duration of residence in Japan (OR = 3.76), no occupation in Brazil (OR = 4.78) and to be living alone in Japan (OR = 5.71). The findings from the acculturation-questionnaire showed that outpatients were most likely to have sociability in Japan with either Brazilians or Japanese only (OR = 3.94) and to hope to hand down either Brazilian or Japanese culture only to their posterity (OR = 5.31). The findings from the acculturation-questionnaire showed that the community sample showed a higher acceptance of both the Brazilian and Japanese culture than the patient sample. We suggested that mentally healthy individuals have a stronger integration orientation as an adaptation modes i.e. to keep the original ethnic-cultural identity on one hand, and to accept the cultural

    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.

    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

    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. PMID:26340638

    Introduction. While extensive scientific evidence exists on the tobacco epidemic, a lack of understanding of both policies and their appropriate way of implementation continues to hinder effective tobacco control. This is especially so in the developing countries such as India. The present study aims to understand current implementation practices and the challenges faced in mainstreaming tobacco control policy and program. Methods. We chose a qualitative study design to conduct the case analysis. A total of 42 in-depth interviews were undertaken with seven district officials in six districts of Andhra Pradesh. A conceptual framework was developed by applying grounded theory for analysis. Analysis was undertaken using case analysis approach. Results and Discussion. Our study revealed that most program managers were unfamiliar with the comprehensive tobacco control policy. Respondents have an ambiguous opinion regarding integration of tobacco control program into existing health and development programs. Respondents perceive lack of resources, low prioritization of tobacco control, and lack of monitoring and evaluation of smoke-free laws as limiting factors affecting implementation of tobacco control policy. Conclusion. The findings of this study highlighted the need for a systematic, organized action plan for effective implementation of tobacco control policy and program. PMID:26933512

    Background More than 200,000 new cases of leprosy were reported by 105 countries in 2011. The disease is a public health problem in Brazil, particularly within high-burden pockets in the Amazon region where leprosy is hyperendemic among children. Methodology We applied geographic information systems and spatial analysis to determine the spatio-temporal pattern of leprosy cases in a hyperendemic municipality of the Brazilian Amazon region (Castanhal). Moreover, we performed active surveillance to collect clinical, epidemiological and serological data of the household contacts of people affected by leprosy and school children in the general population. The occurrence of subclinical infection and overt disease among the evaluated individuals was correlated with the spatio-temporal pattern of leprosy. Principal Findings The pattern of leprosy cases showed significant spatio-temporal heterogeneity (p<0.01). Considering 499 mapped cases, we found spatial clusters of high and low detection rates and spatial autocorrelation of individual cases at fine spatio-temporal scales. The relative risk of contracting leprosy in one specific cluster with a high detection rate is almost four times the risk in the areas of low detection rate (RR = 3.86; 95% CI = 2.26–6.59; p<0.0001). Eight new cases were detected among 302 evaluated household contacts: two living in areas of clusters of high detection rate and six in hyperendemic census tracts. Of 188 examined students, 134 (71.3%) lived in hyperendemic areas, 120 (63.8%) were dwelling less than 100 meters of at least one reported leprosy case, 125 (66.5%) showed immunological evidence (positive anti-PGL-I IgM titer) of subclinical infection, and 9 (4.8%) were diagnosed with leprosy (8 within 200 meters of a case living in the same area). Conclusions/Significance Spatial analysis provided a better understanding of the high rate of early childhood leprosy transmission in this region. These findings can be applied to guide

    There are few studies on the delivery of nursing services in hospitals participating in the Brazilian universal public health system (Sistema Unico de Saúde), which was put in place in 1988. This study, which examined possible changes in the delivery of these services since universal health care was implemented, was based on interviews carried out between July and September 1995 with 31 nurses working at a teaching hospital in the city of Ribeirão Preto, in the state of São Paulo. The nurses had begun working at the hospital between May 1980 and May 1987. Thematic analysis was used to assess their answers. According to the nurses, patients treated after the universal system was implemented have had more complex medical needs and a higher socioeconomic status. In addition, nurses reported an increase in the complexity of patient demands and in the variety of medical specialties offered by the hospital, as well as a decrease in the length of inpatient stays. Forty-six percent of the interviewees reported a change in the work done by nursing staff (for example, nurses have less time available for each patient). Not all of the problems the nurses mentioned are related to the public health system (understaffing is one example). It is essential that nurses examine national health policy and that they engage in the (re)construction of the practice of health care delivery. Nurses ought to understand the reality of their institutions and carry out a management process geared towards the expectations of patients and of health care workers.

  13. A multivariate-based conflict prediction model for a Brazilian freeway.

    Real-time collision risk prediction models relying on traffic data can be useful in dynamic management systems seeking at improving traffic safety. Models have been proposed to predict crash occurrence and collision risk in order to proactively improve safety. This paper presents a multivariate-based framework for selecting variables for a conflict prediction model on the Brazilian BR-290/RS freeway. The Bhattacharyya Distance (BD) and Principal Component Analysis (PCA) are applied to a dataset comprised of variables that potentially help to explain occurrence of traffic conflicts; the parameters yielded by such multivariate techniques give rise to a variable importance index that guides variables removal for later selection. Next, the selected variables are inserted into a Linear Discriminant Analysis (LDA) model to estimate conflict occurrence. A matched control-case technique is applied using traffic data processed from surveillance cameras at a segment of a Brazilian freeway. Results indicate that the variables that significantly impacted on the model are associated to total flow, difference between standard deviation of lanes' occupancy, and the speed's coefficient of variation. The model allowed to asses a characteristic behavior of major Brazilian's freeways, by identifying the Brazilian typical heterogeneity of traffic pattern among lanes, which leads to aggressive maneuvers. Results also indicate that the developed LDA-PCA model outperforms the LDA-BD model. The LDA-PCA model yields average 76% classification accuracy, and average 87% sensitivity (which measures the rate of conflicts correctly predicted).

    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.

    Background: 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). Objective: 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. Method: 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. Results: We evaluated 74 women and 60 men. The equations were as follows: MIP=63.27-0.55 (age)+17.96 (gender)+0.58 (weight), r2 of 34% and MEP= - 61.41+2.29 (age) - 0.03(age2)+33.72 (gender)+1.40 (waist), r2 of 49%. Conclusion: In clinical practice, these equations could be used to calculate the predicted values of MIP and MEP for the Brazilian population.

    The genetic variability of butyrylcholinesterase, determined by the BCHE and CHE2 loci, was examined in nine Brazilian Indian groups. In addition, a search for the presence of the BCHE*F allele was also performed in eight other Brazilian Indian samples and in five admixed (black-Indian-white) rural Amazonian communities previously studied for the CHE2 locus and the BCHE*A allele. In the Indian populations the frequency of the BCHE*F allele varied from 0 to 7.1% +/- 3.4 and the frequency of the CHE2 C5+ phenotype ranged from 1.4% +/- 1.4 to 45.9% +/- 3.8. This study seems to be the first to report the presence of the BCHE*F allele in native Americans. The BCHE*A allele appeared in one Indian group (1.4% +/- 1.0), and we suggest that its existence in this tribe and in other native Americans can be explained by gene flow from white populations. Gene flow may also be the reason for the occurrence of the BCHE*F allele in Brazilian Indians, whereas the CHE2*C5+ allele may have been present in the paleo-Indians. The distributions of both the BCHE*F allele and the CHE2 C5+ phenotype in Brazilian Indians seem to be the result of the action of random genetic drift.

    ABSTRACT Introduction: The Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) is a multi-item psychometric instrument used to assess patients' perspective of the impact specifically related to Orthodontics. The cross-culturally adapted Brazilian version of the PIDAQ has demonstrated good reliability, validity and acceptability. Objective: The aim of the present study was to test the validity and reliability of the Brazilian version of the PIDAQ for use among adolescents aged between 11 and 14 years old. Methods: Having established the possibility of maintaining the operational characteristics of the Brazilian version of PIDAQ for the target age group, 194 individuals in the city of Belo Horizonte, Brazil, completed the questionnaire. The subjects were examined for the presence/absence of malocclusion based on the criteria of the Dental Aesthetic Index (DAI) to test discriminant validity. Internal consistency was measured by means of Cronbach's alpha coefficient which ranged from 0.59 to 0.86 for the subscales. Test-retest reliability was assessed by means of intraclass correlation coefficient which ranged from 0.54 to 0.89 for aesthetic concern and psychological impact. Results: Discriminant validity revealed that subjects without malocclusion had different PIDAQ scores in comparison to those with malocclusion. Conclusion: These findings suggest that the Brazilian version of PIDAQ for adolescents has satisfactory psychometric properties and is applicable to this age group in Brazil. PMID:27409655

    Examining whether the causal relationships among the performance indicators of the balanced scorecard (BSC) framework exist in hospitals is the aim of this article. Data were collected from all twenty-one general hospitals in a public hospital system and their supervising agency for the 3-year period, 2000-2002. The results of the path analyses identified significant causal relationships among four perspectives in the BSC model. We also verified the relationships among indicators within each perspective, some of which varied as time changed. We conclude that hospital administrators can use path analysis to help them identify and manage leading indicators when adopting the BSC model. However, they should also validate causal relationships between leading and lagging indicators periodically because the management environment changes constantly.

    Community coalitions help to generate policy and environmental changes that address community health problems. This qualitative study examined how one community coalition, Get Fit Kaua'i, catalyzed built environment (BE) policy and infrastructure changes in a rural county in Hawai'i. The purpose was to develop a theory that explained the process by which the community coalition facilitated BE changes to support physical activity. Using a grounded theory approach, semi-structured interviews were conducted with a purposeful sample of 25 stakeholders engaged in the coalition's BE activities. The model to emerge from the coalition interviews consisted of five phases: (1) coalition formation, (2) capacity building, (3) policy development, (4) policy passage, and (5) policy implementation. Community context influenced all of these phases. Although community context limits generalizability, other community coalitions pursuing BE changes can learn from the process of the coalition under study.

    Smith-Magenis syndrome (SMS) is a complex congenital anomaly characterized by craniofacial anomalies, neurological and behavioral disorders. SMS is caused by a deletion in region 17p11.2, which includes the RAI1 gene (90% of cases), or by point mutation in the RAI1 gene (10% of cases). Laboratory diagnosis is through cytogenetic analysis by GTG banding and molecular cytogenetic analysis by FISH. We carried out an active search for patients in Associations of Parents and Friends of Exceptional Children (APAE) of São Paulo and genetic centers in Brazil. Forty-eight patients were screened for mental retardation, craniofacial abnormalities and stereotyped behavior with a diagnosis of SMS. In seven of them, chromosome banding at high resolution demonstrated chromosome 17p11.2 deletions, confirmed by FISH. We also made a meta-analysis of 165 cases reported between 1982 and 2010 to compare with the clinical data of our sample. We demonstrated differences between the frequencies of clinical signs among the cases reported and seven Brazilian cases of this study, such as dental anomalies, strabismus, ear infections, deep hoarse voice, hearing loss, and cardiac defects. Although the gold standard for diagnosis of SMS is FISH, we found that the GTG banding technique developed to evaluate chromosome 17 can be used for the SMS diagnosis in areas where the FISH technique is not available.

    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 by INCRA. Using data from the Brazilian census and the Pastoral Land Commission, the authors examine the characteristics of regions where violent conflict predominates.

He studies the origins of Brazilian culture, the peculiarities the meeting of the African folklore and mysticism with the European folklore has created, and also the results of such interaction. In tracing the origins of Carnival rites, the author points out the significant role played by the dynamic and contagious rhythm of the music, that generates an unrestrained atmosphere in which enthusiastic singing and dancing act as elements of catharsis, liberation, compensation and social integration.

    Dental elements are valuable tools in a study of ancient populations and species, and key-features for human identification; among the dental anthropology field, nonmetric traits, standardized by ASUDAS, are closely related to ancestry. This study aimed to analyze the frequency of six nonmetric traits in a sample from Southeast Brazil, composed by 130 dental casts from individuals aged between 18 and 30, without foreign parents or grandparents. A single examiner observed the presence or absence of shoveling, Carabelli's cusp, fifth cusp, 3-cusped UM2, sixth cusp, and 4-cusped LM2. The frequencies obtained were different from the ones shown by other researches to Amerindian and South American samples, and related to European and sub-Saharan frequencies, showing the influence of this groups in the current Brazilian population. Sexual dimorphism was found in the frequencies of Carabelli's cusp, 3-cusped UM2, and sixth cusp.

    Ten captive neotropical Brazilian feline were submitted to gastroscopic examination and samples of gastric mucosa from fundus, corpus and pyloric antrum were evaluated for the presence of Helicobacter species. Warthin-Starry (WS) staining and PCR assay with species-specific primers and enzymatic cleavage were applied for bacterial detection and identification. Histological lesions were evaluated by haematoxylin and eosin staining. All animals showed normal gross aspect of gastric mucosa. Helicobacter heilmannii was confirmed in 100% of the samples by WS and PCR assay. Mild lymphocytic infiltrate in the lamina propria was observed in eight animals, mainly in the fundus region. Small lymphoid follicles were seen in three animals. No significant association between Helicobacter infection and histological findings was verified. These observations suggest that gastric Helicobacter spp. could be a commensal or a eventual pathogen to captive neotropical feline, and that procedures, way life, and stress level on the shelter apparently had no negative repercussion over the integrity of the stomach.

    To understand evolutionary transformations it is necessary to identify the character states of extinct ancestors. Ancestral character state reconstruction is inherently difficult because it requires an accurate phylogeny, character state data, and a statistical model of transition rates and is fundamentally constrained by missing data such as extinct taxa. We argue that model based ancestral character state reconstruction should be used to generate hypotheses but should not be considered an analytical endpoint. Using the evolution of viviparity and reversals to oviparity in squamates as a case study, we show how anatomical, physiological, and ecological data can be used to evaluate hypotheses about evolutionary transitions. The evolution of squamate viviparity requires changes to the timing of reproductive events and the successive loss of features responsible for building an eggshell. A reversal to oviparity requires that those lost traits re-evolve. We argue that the re-evolution of oviparity is inherently more difficult than the reverse. We outline how the inviability of intermediate phenotypes might present physiological barriers to reversals from viviparity to oviparity. Finally, we show that ecological data supports an oviparous ancestral state for squamates and multiple transitions to viviparity. In summary, we conclude that the first squamates were oviparous, that frequent transitions to viviparity have occurred, and that reversals to oviparity in viviparous lineages either have not occurred or are exceedingly rare. As this evidence supports conclusions that differ from previous ancestral state reconstructions, our paper highlights the importance of incorporating biological evidence to evaluate model-generated hypotheses.

    Industrial societies have altered the earth`s environment in ways that could have important, long-term ecological, economic, and health implications. In this paper the authors define, characterize, and evaluate parameter and outcome uncertainties using a model that links global climate change with predictions of chemical exposure and human health risk in the western region of the US. They illustrate the impact of uncertainty about global climate change on such potential secondary outcomes using as a case study the public health consequences related to the behavior environmentally of hexachlorobenzene (HCB), an ubiquitous multimedia pollutant. They begin by constructing a matrix that reveals the linkage between global environmental change and potential regional human-health effects that might be induced directly and/or indirectly by HCB released into the air and water. This matrix is useful for translating critical uncertainties into terms that can be understood and used by policy makers to formulate strategies against potential adverse irreversible health and economic consequences. Specifically, the authors employ a combined uncertainty/sensitivity analysis to investigate how the HCB that has been released is affected by increasing atmospheric temperature and the accompanying climate alterations that are anticipated and how such uncertainty propagates to affect the expected magnitude and calculational precision of estimates of associated potential human exposures and health effects.

    Background Residents of many cities lack affordable, quality housing. Economically disadvantaged neighborhoods often have high rates of poverty and crime, few institutions that enhance the quality of its residents’ lives, and unsafe environments for walking and other physical activity. Deteriorating housing contributes to asthma-related illness. We describe the redevelopment of High Point, a West Seattle neighborhood, to improve its built environment, increase neighborhood physical activity, and reduce indoor asthma triggers. Community Context High Point is one of Seattle’s most demographically diverse neighborhoods. Prior to redevelopment, it had a distressed infrastructure, rising crime rates, and indoor environments that increased asthma-related illness in children and adolescents. High Point residents and partners developed and implemented a comprehensive redevelopment plan to create a sustainable built environment to increase outdoor physical activity and improve indoor environments. Methods We conducted a retrospective analysis of the High Point redevelopment, organized by the different stages of change in the Community Readiness Model. We also examined the multisector partnerships among government and community groups that contributed to the success of the High Point project. Outcome Overall quality of life for residents improved as a result of neighborhood redevelopment. Physical activity increased, residents reported fewer days of poor physical or mental health, and social connectedness between neighbors grew. Asthma-friendly homes significantly decreased asthma-related illness among children and adolescents. Interpretation Providing affordable, quality housing to low-income families improved individual and neighborhood quality of life. Efforts to create social change and improve the health outcomes for entire populations are more effective when multiple organizations work together to improve neighborhood health. PMID:25376016

    1991-04-01

    This work briefly describes Brazilian colonization of the Paraguayan agricultural frontier, analyzes factors responsible for expelling population from Brazil and for attracting Brazilians to Paraguay, and assesses the economic and social consequences of immigration to the area. Paraguay's vast and sparsely populated agricultural frontier in areas outside the Central subregion underwent a process of intense colonization from the early 1960s to the mid-1980s. The Paraguayan government initiated an ambitious colonization program in 1963 to increase production, relieve population pressure and subdivision of small parcels in the Central subregion, encourage agricultural modernization, and produce a more diversified agriculture. Paraguayan agriculture in the early 1960s suffered from excessive concentration of land in a few hands and resulting exclusion of around 3/4 of workers from ownership and from any possibility of obtaining credit to fund technological improvements. Results of studies 2 decades after implementation of the colonization plan suggest that it has failed in significant areas. Although a considerable population redistribution alleviated pressure in the Central subregion, it apparently resulted more from spontaneous movement of peasants outside the colonization areas than from the official program. Concentration of lands is now occurring in the colonization area. Assistance for agricultural modernization and diversification of production in the peasant sector has been minimal. On the other hand, production of soy, wheat, and cotton for export increased substantially, because of an entrepreneurial agriculture capitalized by foreign as well as national interests The unmet goals of the colonization program would have required structural reforms rather than simple spatial redistribution of the population. Many of the colonists in the 1970s were Brazilian families displaced by mechanized agriculture in the southern states of Parana, Santa Catarina, and Rio

  11. Examining the decomposed brain.

    Examination of the decomposed brain is a largely neglected area of forensic neuropathology. However, careful examination often yields valuable information that may assist in criminal proceedings. Decomposition encompasses the processes of autolysis, putrefaction, and decay. Most decomposed brains will be affected by both autolysis and putrefaction, resulting in a brain that may, at one end of the spectrum, be almost normal or, at the other end, pulpified, depending on the conditions in which the body remained after death and the postmortem interval. Naked eye examination may detect areas of hemorrhage and also guides appropriate sampling for histology. Histological appearances are often better than what would be predicted from the state of the brain. Histology often confirms macroscopic abnormalities and may also reveal other features such as ischemic injury. Silver staining demonstrates neuritic plaques, and immunocytochemistry for β-amyloid precursor protein and other molecules produces results comparable with those seen in well-preserved fixed brains. The usefulness of information derived from the examination of the decomposed brain in criminal proceedings is illustrated with 6 case reports drawn from the author's own practice.

    Objective This study aimed at describing the profiles of Brazilian and international studies published in orthodontic journals. Methods 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). Results 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 were dental materials (17%) and treatment devices (12.4%) in international articles, 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. Conclusions 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 aim of the present study was to assess the mental health status of Japanese-Brazilians living in Kiyoharadai, Japan and compare the findings with the Japanese-Brazilians living in Bauru, Brazil. A comparative community-based mental health survey was conducted from November 1997 to April 1999 on a randomly selected sample of Brazilians of Japanese descent living in Bauru, Brazil (n=213) and on the entire Brazilian community of Kiyoharadai, Utsunomiya, Japan (n=158), using the self-reporting questionnaire (SRQ-20). Analysis was done by chi2, Fisher and multiple logistic regression. Scores indicating probable cases of minor psychiatric disorders, were found in 3.2% of the community in Bauru city and 17.8% (OR=7.01) of the community in Kiyoharadai. The sociodemographic data indicated that those with high SRQ-20 scores were most likely to be female (OR=2.98), smokers (OR=2.76), and those whose former occupation was student when living in Brazil (OR=9.57). The mental health status of the Japanese-Brazilians living in Kiyoharadai, Japan is significantly worse than that of the community living in Bauru, Brazil, particularly among women, smokers and those who were students when living in Brazil. Further research concerning the mental health of this community is necessary and assistance provided.

    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

    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.

    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

    Twenty thousand samples from the Brazilian continental shelf basins were analyzed to characterize and evaluate the hydrocarbon source potential of the areas. The geochemical evaluation of the rock and oil samples was performed by organic carbon determinations, Rock-Eval pyrolysis, vitrinite reflectance, thermal alteration index, liquid and gas chromatographies, gas chromatography-mass spectrometry, and carbon isotope analyses. Three source rock systems have been identified: lower Neocomian shales deposited in a continental environment, upper Neocomian shales grading from continental to lagoonal environment, and Aptian shales related to evaporitic and lacustrine sequences. Upper Cretaceous and Tertiary open marine slope sediments are not considered as source rocks. Locally, these sediments present high organic carbon content but show an extremely poor hydrocarbon yield. Anoxic depositional conditions, nevertheless, can be traced locally along some levels of the Santonian to Cenomanian shales and marls. These sediments are generally immature in the Brazilian margin basins and no oil was generated from this section. Three oil families were distinguished through oil-to-oil and oil-to-source rock correlations: the lower Neocomian continental type, the upper Neocomian continental to lagoonal type, and the Aptian evaporitic to lacustrine related sequences. The geochemical studies, together with geologic and geophysical data, provided the basis to display some models for the migration pathways and habitat of oils in the Brazilian margin basins.

    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.

    Blood lipid levels are determined by a combination of genetic and environmental factors. Higher than average values of high-density lipoprotein cholesterol (HDL-cholesterol) have been observed in people of Japanese ethnicity. The aim of this study was to investigate whether Japanese immigrants to Brazil and subsequent generations maintain the protective benefits associated with higher levels of HDL-cholesterol, and to examine the potential associations between HDL-cholesterol and a variety of other blood lipids, anthropometric and lifestyle factors. Healthy men and women aged 35 years and older who were Native Japanese (n = 198) or Japanese-Brazilians (JB) living in São Paulo, Brazil (n = 198) and in some Japanese cities (n = 246) were investigated. Anthropometric variables, blood lipids including HDL-cholesterol, and lifestyle factors were assessed. Serum HDL-cholesterol was observed to be lower for JB in São Paulo (both women and men) compared with Natives and JB in Japan. Among the groups, triglycerides, waist circumference, LDL-cholesterol, meat intake, stress, and smoking were observed to be independently negatively associated with HDL-cholesterol, whereas total cholesterol, fish intake, and physical activity were positively associated. Lower levels of HDL-cholesterol among both men and women of JB in São Paulo compared with both other groups were confirmed even after lifestyle adjustments. Our findings highlight the significantly lower levels of HDL-cholesterol among Japanese-Brazilians living in São Paulo city compared to Japanese-Brazilians and Native Japanese residing in Japan. Although several lifestyle factors were found to be significantly associated with HDL-cholesterol, they cannot adequately explain the role of the Brazilian cultural environment on HDL-cholesterol levels.

    Certification in Colposcopy by the British Society for Colposcopy and Cervical Pathology (BSCCP) and the Royal College of Obstetricians and Gynaecologists is a formal pre- requisite to the practice of colposcopy within the UK. This certification is awarded after passing an Objective Structured Clinical Examination (OSCE). The aim of the project is to explore examiners' perceptions of the OSCE examination in colposcopy and consider whether it is the right tool to differentiate between safe and unsafe practice in colposcopy. A case study research methodology was employed for the project, and questionnaires were sent to 30 examiners for OSCE in Colposcopy. The project also included conducting semi-structured interviews with two examiners, two trainees and a senior manager of the BSCCP. The questionnaire had a response rate of 28 (94%). The satisfaction rate among the examiners about the standard of questions in OSCE in Colposcopy was 93%, and 89% of the examiners would allow a candidate passing the examination to carry out a clinic in their absence. A total of 26 (94%) examiners thought that the examination was fit for purpose. It was suggested that testing of practical skills should also be made part of the examination. It seems OSCE in Colposcopy is perceived well both by the examiners and the candidates.

    This article reports on an evaluative study of municipal management of the Brazilian National School Nutrition Program in the largest cities in Santa Catarina State, Brazil. The matrix of indicators included two dimensions: political-organizational, with the sub-dimensions resources, inter-sector action, and social control, and operational-technical, organized in nutritional and feeding efficacy, nutritional monitoring, and educational activities for a healthy diet. A total of 22 indicators were determined, and data were collected through interviews with nutritionists. The political-organizational dimension showed 60% of fair cases and 40% of poor cases, while the operational-technical dimension showed 90% of poor cases, resulting from low performance in monitoring and educational activities. Although the cases showed unsatisfactory results, the evaluation provides important data on the management of the Brazilian National School Nutrition Program. The study emphasizes the importance of evaluation for alerting managers to the relevance of reviewing and upgrading activities.

  4. Laxative effects and mechanism of action of Brazilian green propolis

    2012-01-01

    Background Brazilian green propolis is reported to have wide range of biological properties including antibacterial, anti-inflammatory, anti-influenza, and antioxidant activities. In the digestive system, a protective effect of propolis on gastric ulcer has been reported, but a laxative effect has not yet been reported. We investigated the effect and the mechanism of action of water and ethanol extracts of Brazilian green propolis. Methods We examined the laxative effect of propolis on stool frequency by administering orally an ethanol extract of propolis (EEP) or a water extract of propolis (WEP) at 10, 50, 100, or 500 mg/kg to normal mice. We then investigated the effects of propolis using constipation model mice induced by two types of drugs, loperamide (a μ opioid receptor agonist) and clonidine (an α-2 adrenergic receptor agonist). We also investigated the effects of WEP on gastrointestinal transit and contractional tension of the ileum to uncover the mechanism of action of WEP. Results Treatment with WEP, but not with EEP, significantly increased the weight of stools (p<0.01 at 500 mg/kg). WEP treatment significantly restored stool frequency and stool weight in clonidine-induced constipation model mice, but not in loperamide-induced constipation model mice. WEP treatment did not affect gastro-intestinal transit, but significantly increased the contractional tension of the isolated ileum of guinea pigs. This increase was inhibited by an acetylcholine receptor antagonist (atropine), but not by a 5-HT receptor antagonist (GR113808). Conclusion These findings indicate that WEP has laxative effects both in normal mice and in clonidine-induced constipation model mice. The laxative effects of WEP might be mediated by increased contractional tension of the ileum exerted at least in part via activation of an acetylcholine receptor. PMID:23088672

    Japanese-Brazilians were the third largest immigrant group in Japan in 2011. Their health issues have caused concern, as their limited language made them vulnerable by hindering access to health services. Upon considering child health, mothers' health literacy (HL) is very important. This study aimed to develop a health literacy scale among Brazilian mothers (HLSBM) in Japan. Questionnaires in Portuguese were distributed to 1474 mothers from December 2011 to March 2012. Among 698 collected, 558 questionnaires were analyzed. We prepared 29 candidate items for HLSBM based on Nutbeam's concept of functional, interactive and critical literacy. The dimensional structure was determined statistically using confirmatory factor analysis. Validity was also analyzed by Pearson's correlation with Ishikawa's scale and Kendall's coefficient of concordance among researchers. Cronbach's α coefficients were calculated to examine internal consistency. The confirmatory factor analysis revealed a two-factor model (five items for basic literacy and five items for critical literacy) with sufficient goodness of fit (GFI 969, AGFI 945, NFI 959, CFI 972, RMSEA 060). The internal consistency values of the total score, basic and critical literacy sub-scales were 0.819, 0.889 and 0.667, respectively. Kendall's coefficient of concordance showed good agreement of researchers (p < 0.001). Pearson's correlation coefficients with Ishikawa's scale were 0.554 for total score, 0.446 for basic literacy and 0.472 for critical literacy. The HLSBM consisting of two factors was confirmed to be valid and reliable. The HLSBM must be useful for understanding this vulnerable group's health literacy and its associated factors.

MTHFR C677T, A1298C, and G1793A; MTRR A66G; and MTR A2756G polymorphisms were studied by quantitative polymerase chain reaction (qPCR). The results were analyzed statistically and a P value <.05 was considered significant. Single-marker analysis revealed a significant association among MTHFR C677T polymorphism and both NOA group (P = .018) and SO group (P < .001). Considering the MTHFR A1298C, MTHFR G1793A, and MTRR A66G polymorphisms, no difference was found between NOA group and SO group. Regarding the MTR A2756G polymorphism, a significant difference was found between NOA and controls, P = .017. However, statistical analysis revealed no association between SO group and controls. Combined genotypes of 3 MTHFR polymorphisms did not identify a haplotype associated with idiopathic infertility. The combinatory analysis of the 3 polymorphisms MTHFR, MTRR, and MTR did not show difference between cases and controls. The findings suggest the MTHFR C677T and MTR A2756G polymorphisms could be an important genetic factor predisposing to idiopathic infertility in Brazilian men.

    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.

    2010-06-01

    Throughout the last years, there has been a growing interest in ongoing assessment proposals in Latin America, which are more far-reaching and not traditional. The aim of this study was to analyze the potential of qualitative-participatory evaluation in view of the challenge of strengthening health reforms in the region, particularly those considered progressive, such as the Brazilian case. There is the need to assess health reforms in a rigorous and permanent way, especially the incongruity when using normative models to evaluate health systems based on principles of universality, comprehensiveness, humanization and democratic management. In addition to the demand for assessment instruments and strategies, the Brazilian health reform requires the adoption of evaluation proposals and practices that are founded on other paradigms, distinct from the hegemonic one, in the sphere of health assessment. It is recommended that emerging evaluative models be used, such as those with a qualitative-participatory approach.

  10. Haemochromatosis in a Brazilian tapir (Tapirus terrestris) in an Australian zoo.

    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.

    Objectives: The purpose of this study was to determine the clinical and demographic characteristics of oral non-odontogenic cysts (ONOC) in a Brazilian population over a 53-year period and to compare this data with the literature. Study Design: A total of 20.391 biopsies records were evaluated, from April/1959 to August/2012. Cases of oral developmental cysts were selected. Data regarding age, gender, time of evolution, and anatomic site of all cases were collected. The data were analyzed by descriptive statistics. Results: Among 20.391 oral biopsies, 71 (0.35%) met the criteria of ONOC. Females accounted for 50.70% of all cases. The mean age observed was 38.14 years (range: 5-88 years). Nasopalatine duct cysts, oral lymphoepithelial cysts and epidermoid cysts were the most common ONOC, accounting for 63 cases (88.73%). Nasopalatine duct cysts occurred in 31 cases (43.66%), followed by 22 patients with oral lymphoepithelial cysts (30.99%) and 10 cases of epidermoid cysts (14.08%). Nasopalatine duct cysts revealed predominance among males (58.06). Oral lymphoepithelial cysts were more commonly observed in tongue (50%). Epidermoid cysts were most frequently found in the buccal mucosa (40.00%). Conclusions: The differential diagnosis of ONOC is based on the clinical, radiological, and histological findings. It is difficult to establish an epidemiological profile of ONOCs, considering the low frequency of these lesions and the divergences in the demographic and clinical presentation data among different populations. Key words:Diagnosis, epidemiology, jaw cysts, mouth. PMID:24316702

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

    2010-01-01

    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

    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.

    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.

    The approach of the Social License to Operate (SLO) emerges as an important element in academic discussions and business practices related to extractive industries. It appears that in productive activities with great potential to produce economic, social and environmental impacts, conventional approaches based on legal compliance no longer sufficient to legitimize the actions of companies and engagement stakeholders. Studies highlight the need of mining activities receiving a SLO "issued" by companies stakeholders, including society, government, non-governmental organizations, media and communities. However, local communities appears as major stakeholders in governance arrangements, by virtue of its proximity to extractive areas and ability to affect the company's results. Stakeholders with unmet expectations can generate conflicts and risks to the company, the knowledge of these expectations and an awareness of company managers of the importance of Social License to Operate (SLO), can generate strategies and mitigating actions to prevent and or minimize possible conflicts. The concept of SLO arises in engineering extractive industry, when you need to respond to social challenges, beyond the usual environmental challenges, technological and management. According to Franks and Cohen (2012) there is a tendency of engineering sectors, sustainability, environmental, safety and especially in risk mappings, treat the technological issues in a neutral manner, separating the technological research projects of social influences. I want to contribute to the advancement of the debate on stakeholder engagement and adopting as focus on the company's relationship with the community, the aim of this study was to understand how a social project held by one of the largest mining companies in Brazil contributed to the process of SLO. This methodological procedure adopted was a qualitative, descriptive, and exploratory interviews with the communities located in rural areas of direct influence of the company's approach. The results show that the strategy adopted by the company contributed to the process of SLO, furthermore it is necessary adopt strong methodologies that facilitate the engagement processes of the other company's stakeholders, as well as the challenge to keep on local legitimacy earned.

This is the seventh such meeting, and the first one to have contributed papers published in the Journal of Physics: Conference Series. The previous meetings in the BMSP series took place in the mountains of Minas Gerais and in the region of the Brazilian Pantanal. Now, for the first time, the Meeting was held in the pleasant shores of João Pessoa, the capital of the Paraíba state. The VIIth BMSP brought together more than 50 researchers from all over the world for a vibrant and productive period. As in the previous meetings, the talks and posters highlighted recent advances in applications, algorithms, and implementations of computer simulation methods for the study of condensed matter, materials, out of equilibrium, quantum and biologically motivated systems. We are sure that this meeting series will continue to provide a valuable venue for people working in simulational physics to exchange ideas and discuss the state of art of this always expanding field. We are very glad to realize this special issue, and are most appreciative to the editors of the Journal of Physics: Conference Series for making this publication possible. We are grateful for the outstanding work of the João Pessoa team, for the financial support of the Brazilian agencies CNPq, CAPES, FAPESQ, and of the Federal Universities UFPB and UFMG. At last, but not least, we would like to acknowledge all of the authors of this special issue for their contributions. João Antonio Plascak Alexandre Rosas Guest Editors Conference photograph

    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

    This paper discusses the Brazilian Supreme Court ruling on the case of anencephaly. In Brazil, abortion is a crime against the life of a fetus, and selective abortion of non-viable fetuses is prohibited. Following a paradigmatic case discussed by the Brazilian Supreme Court in 2004, the use of abortion was authorized in the case of a fetus with anencephaly. The objective of this paper is to analyze the ethical arguments of the case, in particular the strategy of avoiding the moral status of the fetus, the cornerstone thesis of the Catholic Church.

    The study of radiation defects created in biomaterials, such as bone and teeth, can be used in dating with importance to palaeontology and archaeology. Two Stegomastodon teeth (AL1 and AL2) from north-eastern Brazilian megafauna were studied by electron spin resonance (ESR) spectroscopy. The samples were collected in Fazenda Ovo da Ema, (913349 / 3714965) UTM, Alagoas state, Brazil. The dating of these samples can contribute to the better knowledge of megafauna presence in this region as well as to the events associated to the extinction of these species.

    Brazilian keratin treatments are widely available products that are used by women all over the world to straighten hair. Marketers of these products claim that the keratin treatments render naturally curly hair more manageable and frizz-free while enhancing color and shine, giving the hair a healthier appearance. Although widely used, there have been virtually no reports of adverse side effects. Unfortunately, many of the products that are applied by salon professionals contain formaldehyde or its derivatives and are being marketed as safe.

    The general purpose of this research was to use recent satellite-based estimates of deforestation in Brazilian Amazonia to calculate the net flux of carbon associated with deforestation and subsequent regrowth of secondary forests. We have made such a calculation, in the process comparing two estimates of deforestation and two estimates of biomass for the region. Both estimates were based on the RADAMBRASIL survey. They differed in the equations used to convert wood-volumes to total biomass. The net flux of carbon from changes in land use seems to vary from year to year, perhaps by as much as a factor of 4.

    "Since the 1950s, the population of Eastern regions of Paraguay has grown with the steady influx of Brazilian immigrants. Planters from Parana and Sao Paulo, mechanized wheat and soy farmers from the southern campos and cattle farmers from the Matto Grosso do Sul have joined mixed farmers, descendants of European settlers from the south of Brazil. Despite some local conflicts, the Brazilguayans...[in] Oriente [province] seem to be on the road to integration in Paraguay." (SUMMARY IN ENG AND SPA AND POR)

    The metopic suture is located between the tubercles of the frontal bone. There are divergences regarding the exact time at which it closes, which ranges from the first to the tenth year of life, although it may persist into adulthood. This study was conducted on 134 dry crania from adult Brazilians, of which 95 were male and 39 were female. These were available in the anatomy laboratories of higher education institutions in Maceió, AL, Brazil. All the crania were examined macroscopically with regard to the presence (metopism: M) on absence of the metopic suture. M was considered to be complete (Mc) when it continued uninterruptedly from the nasium to the bregma and incomplete (Mi) when it was not present over its entire length. It was observed that Mc was present in 4.48% (6/134) of the skull examined, of which 50% (3/134) were male and 50% (3/134) were female. An incomplete metopic suture was found in 5.22% (7/144) of the crania and more frequently among males (3.73%; 5/134). Among the crania with a metopic suture, the dolichocephalic type predominated (7.46%) in relation to brachycephalic crania (1.49%) and mesocephalic crania (0.74%). There was no predominance of metopism between the sexes, while an incomplete metopic suture was slightly more common among males. PMID:25938094

    Molecular surveillance provides a powerful approach to monitoring the resistance status of parasite populations in the field and for understanding resistance evolution. Oxamniquine was used to treat Brazilian schistosomiasis patients (mid-1970s to mid-2000s) and several cases of parasite infections resistant to treatment were recorded. The gene underlying resistance (SmSULT-OR) encodes a sulfotransferase required for intracellular drug activation. Resistance has a recessive basis and occurs when both SmSULT-OR alleles encode for defective proteins. Here we examine SmSULT-OR sequence variation in a natural schistosome population in Brazil ∼40years after the first use of this drug. We sequenced SmSULT-OR from 189 individual miracidia (1-11 per patient) recovered from 49 patients, and tested proteins expressed from putative resistance alleles for their ability to activate oxamniquine. We found nine mutations (four non-synonymous single nucleotide polymorphisms, three non-coding single nucleotide polymorphisms and two indels). Both mutations (p.E142del and p.C35R) identified previously were recovered in this field population. We also found two additional mutations (a splice site variant and 1bp coding insertion) predicted to encode non-functional truncated proteins. Two additional substitutions (p.G206V, p.N215Y) tested had no impact on oxamniquine activation. Three results are of particular interest: (i) we recovered the p.E142del mutation from the field: this same deletion is responsible for resistance in an oxamniquine selected laboratory parasite population; (ii) frequencies of resistance alleles are extremely low (0.27-0.8%), perhaps due to fitness costs associated with carriage of these alleles; (iii) that four independent resistant alleles were found is consistent with the idea that multiple mutations can generate loss-of-function alleles.

    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
