    We established Project Viva to examine prenatal diet and other factors in relation to maternal and child health. We recruited pregnant women at their initial prenatal visit in eastern Massachusetts between 1999 and 2002. Exclusion criteria included multiple gestation, inability to answer questions in English, gestational age ≥22 weeks at recruitment and plans to move away before delivery. We completed in-person visits with mothers during pregnancy in the late first (median 9.9 weeks of gestation) and second (median 27.9 weeks) trimesters. We saw mothers and children in the hospital during the delivery admission and during infancy (median age 6.3 months), early childhood (median 3.2 years) and mid-childhood (median 7.7 years). We collected information from mothers via interviews and questionnaires, performed anthropometric and neurodevelopmental assessments and collected biosamples. We have collected additional information from medical records and from mailed questionnaires sent annually to mothers between in-person visits and to children beginning at age 9 years. From 2341 eligible women, there were 2128 live births; 1279 mother-child pairs provided data at the mid-childhood visit. Primary study outcomes include pregnancy outcomes, maternal mental and cardiometabolic health and child neurodevelopment, asthma/atopy and obesity/cardiometabolic health.

    Presenting a thesis and then undertaking the viva is challenging even for the most experienced of researchers. This paper offers stylistic practicalities, reflects on thesis and viva preparation, and discusses the research regulations and submission requirements of higher education institutions (HEIs). Issues such as the use of the first person, how best to locate research in the professional setting, research regulations and codes of practice are discussed, along with some guiding principles to enable effective viva preparation. It is derived from experience as a doctoral student, supervisor and examiner, and focuses on questions most frequently asked by doctoral students.

  6. Viva viva? Women's meanings associated with male nudity in a 1970s "for women" magazine.

    PubMed

    Beggan, James K; Allison, Scott T

    2009-01-01

    Little research has been conducted with regard to how women view male nudity. The purpose of this analysis was to present an historical case study of Viva, a 1970s women's magazine geared toward the presentation of male nudity. Implicit in Viva's editorial direction was the assumption that women's sexuality is socially constructed and, thus, modifiable but also homologous to men's sexuality. Using sexual scripting theory as a sensitizing concept, a content analysis of women's letters to the editor was conducted. Letters justified inclusion of male nudity on the basis of principles of fairness and equality with men. In addition, letters tried to demarcate boundary conditions for what constituted acceptable male nudity in terms of the presence of erection, size, shape, and coloring of the penis, and whether inclusion of the penis was contextualized by other physical traits such as body musculature. Despite an early effort to modify cultural scripts on the basis of a constructivist world view, it was found that, ultimately, Viva advocated an essentialist viewpoint that reified existing conceptualizations of female sexuality as both static and uninterested in the visual representation of sexually related material. This study explored whether Viva's essentialist final position may have reflected financial exigencies rather than ideologies.

  12. The clinical viva: an assessment of clinical thinking.

    PubMed

    Roberts, Debbie

    2013-04-01

    In order to enable Masters level pre-registration students to demonstrate sophisticated cognitive abilities, integration of knowledge, complex problem solving, critical opinion, lateral thinking and innovative action; an innovative assessment tool is required (Sadler, 2009). A clinical viva was devised to enable third year students in their final transitional placement prior to qualifying demonstrate both the art and science of nursing practice. The assessment combines some of the viva element of an Australian assessment model described by Levett-Jones et al. (2011), together with the think aloud approach suggested by Banning (2008); whereby the think aloud model acts as a catalyst for eliciting students' understandings and knowledge and the SOAP model is a mechanism for the assessment of students' understandings and knowledge. Rust (2002) calls for students to be afforded opportunities for regular formative feedback; therefore, the assessment includes a replica formative assessment, one week prior to the summative assessment. This formative test prevents assessment being seen as a snapshot of the student's development and encourages assessment for learning and is an approach which is suggested to discourage surface learning (Rust, 2002). A holistic rubric was developed in an attempt to capture the students' abilities against the six cognitive operators or heuristics suggested by Banning (2008). Open-ended questions were devised to be asked of the students as advocated by Levett-Jones et al. (2011), to uncover the student's cognitive abilities, integration of knowledge, complex problem solving, critical opinion, lateral thinking and innovative action. Roberts (2011) calls for new and innovative ways of assessing student learning which bridges the artificial divide between theory and practice and enables students to demonstrate both the art and science of nursing practice (p610). The clinical viva has the potential to be one such mechanism.

  17. VIVA (from virus variance), a library to reconstruct icosahedral viruses based on the variance of structural models.

    PubMed

    Cantele, Francesca; Lanzavecchia, Salvatore; Bellon, Pier Luigi

    2004-11-01

    VIVA is a software library that obtains low-resolution models of icosahedral viruses from projections observed at the electron microscope. VIVA works in a fully automatic way without any initial model. This feature eliminates the possibility of bias that could originate from the alignment of the projections to an external preliminary model. VIVA determines the viewing direction of the virus images by computation of sets of single particle reconstruction (SPR) followed by a variance analysis and classification of the 3D models. All structures are reduced in size to speed up computation. This limits the resolution of a VIVA reconstruction. The models obtained can be subsequently refined at best with use of standard libraries. Up today, VIVA has successfully solved the structure of all viruses tested, some of which being considered refractory particles. The VIVA library is written in 'C' language and is devised to run on widespread Linux computers.

  18. Viva Mulher: constructing a cervical cancer control program in Brazil.

    Porto, Marco Antonio; Habib, Paula Arantes Botelho Briglia

    2014-01-01

    Through a number of isolated initiatives that began in the 1960s, Brazil accumulated knowledge and experience that in the late 1990s culminated in the implementation of the first nationwide public health action meant to coordinate health bodies and personnel from the federal, state, and municipal administrative levels to address a chronic degenerative disease. The main goal of this article is to analyze the process of construction of this public policy for cancer control in Brazil--more specifically, organized screening for the control of cervical cancer in the form of the Viva Mulher program. Our analytical approach relies on elements from the history of public policy and from the history of institutions, combining the use of documental sources, scientific literature, and interviews with managers involved in the process under study. Our analysis endeavors to show how and to what extent this national process incorporated the experiences of local projects and responded both to pressure from the social movement and to the country's political environment. It further shows how the new context, shaped by changes in the organization of the Brazilian health system, influenced this process.

  19. Evaluation of Reliability in Structured Viva Voce As a Formative Assessment of Dental Students.

    PubMed

    Ganji, Kiran Kumar

    2017-05-01

    An oral assessment is a direct way to assess students' learning outcomes by questioning them. The format of oral examinations (viva voce) is not uniform. Unlike interviews, which usually have structured question lists, oral assessments usually do not have a question structure. Structured viva voce overcomes the weaknesses of traditional viva voce The aim of this study was to assess the reliability of structured viva voce as a formative assessment of dental students. A sample of 65 third-year and 70 fourth-year dental students at one dental school in India were subjected to structured viva voce examinations with questions derived from the subject of periodontics. Each examinee answered five questions (two open and three closed) asked by trained unbiased examiners. The structured viva voce examinations were conducted on the seventh and 14th days after the last lecture of a one-month lecture series. Scores were tabulated into three domains of Bloom's taxonomy: knowledge, comprehension, and application. Regarding knowledge, the mean scores were 1.24±0.59 (seventh day) and 1.66±0.64 (14th day), and the difference was statistically significant (p<0.05). Regarding comprehension, the mean scores were 0.92±0.57 (seventh day) and 1.44±0.65 (14th day), and the difference was statistically significant (p<0.05). Regarding application, the mean scores were 0.56±0.50 (seventh day) and 1.0±0.43 (14th day) in Domain II, and the difference was statistically significant (p<0.05). The results suggest that structured viva voce was a reliable method for the formative assessment of these dental students.

  20. Improving Memory Subsystem Performance Using ViVA: Virtual Vector Architecture

    2009-01-12

    The disparity between microprocessor clock frequencies and memory latency is a primary reason why many demanding applications run well below peak achievable performance. Software controlled scratchpad memories, such as the Cell local store, attempt to ameliorate this discrepancy by enabling precise control over memory movement; however, scratchpad technology confronts the programmer and compiler with an unfamiliar and difficult programming model. In this work, we present the Virtual Vector Architecture (ViVA), which combines the memory semantics of vector computers with a software-controlled scratchpad memory in order to provide a more effective and practical approach to latency hiding. ViVA requires minimal changes to the core design and could thus be easily integrated with conventional processor cores. To validate our approach, we implemented ViVA on the Mambo cycle-accurate full system simulator, which was carefully calibrated to match the performance on our underlying PowerPC Apple G5 architecture. Results show that ViVA is able to deliver significant performance benefits over scalar techniques for a variety of memory access patterns as well as two important memory-bound compact kernels, corner turn and sparse matrix-vector multiplication -- achieving 2x-13x improvement compared the scalar version. Overall, our preliminary ViVA exploration points to a promising approach for improving application performance on leading microprocessors with minimal design and complexity costs, in a power efficient manner.

  1. Examining the British PhD viva: opening new doors or scarring for life?

    PubMed

    Carter, Bernie; Whittaker, Karen

    2009-01-01

    The PhD viva -- regardless of its format -- has the potential to be a significant rite of passage for the student. It is an experience that can resonate for months or years afterwards. Part of the challenge is that for everyone involved -- student, supervisory team and examiners -- a degree of end-point uncertainty exists. These ambiguities and tensions are perhaps an inherent part of any examination but are particularly characteristic of the examination of the individual and unique body of work that constitutes the doctoral thesis. In recent years, increased attention has been placed on the processes that surround the examination, aiming to increase transparency, consistency and fairness. However, the process of examining a student and their thesis remains challenging and is surrounded by different agendas, ideologies and practices. This paper examines some of the issues surrounding the PhD viva, primarily focusing on the British viva whilst weaving in commentary about the Australian system.

    Objective: Viva voce examination is an important tool of evaluation in medical examinations marred by high subjectivity. Gross subjectivity in viva voce assessment can be reduced by structuring it. Materials and Methods: The marks obtained in theory and viva voce (traditional viva voce examination [TVVE]) of I sessional, II MBBS students were compared and a huge disparity was identified. A structured viva voce examination (SVVE) was then proposed and experimented as an objective and standardized alternative. Sets of equitable question cards for SVVE were prepared, each having eight questions with two parts each, arranged successively with increasing difficulty, domains of learning, and appropriate marks. The percentage variation in scoring in viva versus theory marks was calculated for both TVVE and SVVE, and students were grouped as Group I (+100 to +51%); Group II (+50 to −50%); Group III (−51 to −100%); Group IV (−101 to −150%); Group V (−151 to −200%); and Group VI (< −200%) variation, as? inappropriate, appropriate, inappropriate, erroneous, more erroneous and most erroneous respectively. Student’s feedback on the SVVE was also obtained. Results: In TVVE (n = 128), the students distributed were:none,17.2%, 23.4%, 22.7%, 11.7% and 25% in Group I, II, III, IV, V, and VI in contrast to SVVE (n = 107) as 7.5%, 57.9%, 19.6%, 6.5%, 5.6%, and 2.8%, respectively. Marked disparity of TVVE was annulled with SVVE. Student’s feedback was quite encouraging with 83% overall acceptability and almost 66% preferred SVVE. Conclusion: SVVE was more realistic as compared to TVVE. Most of the students favored this approach. PMID:28031609

    Sleep is an important determinant of keeping healthy physically and mentally. Deviation in sleep is a common problem among students during examinations. The purpose of this study is to determine students' sleep pattern during night preceding viva examination and its correlation with performance. This was a cross-sectional prospective study conducted between January and February 2014 among 1st and 2nd year MBBS students of National Medical College, Birgunj, Nepal who appeared in University's final practical examinations. Based on simple random sampling approach, each of the 280 participants was allowed to pick out five pieces of lottery papers and they were asked the five questions resembling the number in the list of questions. Among the total 280 students, 74.6% were from India and 25.4% were from Nepal, and majorities (63%) of them were males. Fifty two percent of the students either could not sleep at all or slept just for 1 to 1.5 hours while 12% slept for 5 to 6.5 hours. Two-third (66%) of the students was able enough to achieve one to two scores, and only 1.8% could succeed to get the maximum score of five. The correlation between hours of sleep preceding examination and the score achieved was positively (r=0.701) and statistically significantly correlated (p<0.001). There is a trend among the medical students either not to sleep or sleep only for few hours preceding viva examination that result in poor performance in examinations.

  12. Vulnerable but aloof versus naughty and nice: contrasting the presentation of male and female nude models in Viva and Playboy.

    PubMed

    Beggan, James K; Vencill, Jennifer A; Garos, Sheila

    2014-01-01

    The current research examined contested meanings of nudity by comparing images of nude men and women that appeared in Viva, a 1970s women's magazine founded with the intention of foregrounding male nudity, to corresponding issues of Playboy. A major difference was obtained between male models and Playboy Playmates regarding direction of gaze and nudity. Although gaze aversion is often interpreted as a sign of submission and direct gaze is seen as a dominance cue, men in Viva displayed a high level of gaze aversion and women in Playboy often gazed directly at the camera, especially when their pubic area was exposed. Additional content analysis examined the personality characteristics attributed to male models in Viva and Playmates in Playboy in their biographical sketches. In Viva, men were presented as possessing "bad boy" traits that may have been intended to compensate for the loss of power associated with male nudity. Playmates could be viewed as being naughty (by virtue of posing nude) and nice in the characterization of their personalities.

    2017-04-01

    Science outreach and engagement are crucial core objectives of the Lagos Ciência Viva Science Centre (CCVL). By engaging audiences in the real world a link is made between their science centre experience and the environment in which they live. Therefore, it has been an option of the CCVL to offer geological outdoor activities, both in the natural environment and urban context. Dinosaurs are an appealing science subject for both students and tourists. Thus, the CCVL has a long tradition in organizing and guiding field trips to two dinosaur track sites - Salema and Santa beaches (Vila do Bispo, southwest Algarve). These sites, both from the Lower Cretaceous reveal at least two types of tracks - theropod and iguanodontian footprints. Often in combination with the paleontology field trips, the CCVL also offers different geological field trips both for formal (school) and informal (tourism) education. This allows students and tourists to be introduced to dinosaur paleobiology and ichnology and to the structural geology and stratigraphy of the area. Our science outreach is being further developed by contractual agreement with a regional tour operator, in which the CCVL is responsible for the scientific content and guidance of the visits. Aiming at an urban context, the CCVL produced three Urban Geology and Paleontology Guide Books for three Algarve cities (Lagos, Faro and Tavira), which can be acquired in the three Ciência Viva Science Centres shops as well as in the tourist information offices serving this way as a basis for guided urban tours also offered by the CCVL. Based on our experience, we review and contextualise these geoscience activities and their potential for science outreach, communication and tourism. We discuss and propose a classification of different possibilities in geoscience communication and outreach based on three vertices: Science, Heritage and Geotourism. Some particularities of these visits, such as the merge between geosciences and other

    For a six-month period, all airway options used for non-emergent patients undergoing thoracic surgery requiring one-lung ventilation at a single institution were assessed after introduction of the VivaSight™ double-lumen endotracheal tube (VivaSight-DL), a novel double-lumen tube with an integrated camera. This device displays a continuous view of the position of the tube relative to the carina. A total of 72 patients had lung separation with the VivaSight-DL. Lung separation was achieved on first attempt without additional manipulation in 85% of cases. In only three cases (4%) was a fibreoptic bronchoscope required, in each instance to reposition the tube after intraoperative dislodgement. The VivaSight-DL represents a novel method of one-lung ventilation allowing rapid identification of intraoperative airway problems and reducing the need for fibreoptic bronchoscopy.

    2016-12-01

    This cross-sectional study aimed to analyze the cases of falls in urgent and emergency care services of 24 Brazilian capitals and the Federal District participating in the 2014 VIVA Survey. We sought to describe the epidemiological profile of victims, characterizing the event and the severity of injuries it caused and to perform an association study. We calculated the simple and relative frequencies of variables and performed multivariate logistic regression analysis for complex sample data in order to verify associations between falls and selected variables. Fall victims profile results show a predominance of males, age groups 0-9years and 20-39 years and brown skin. Outcomes show that 56% fell from own height, public road was the most frequent place of falls and 92.7% of people receiving care for falls suffered some kind of injury, of which most common were bruises, sprain and strains, followed by cut/laceration. In the final model, we were able to associate fall with gender, age, education, disability and place of the event. The likelihood of falls at school is 14% higher than at home, but falls in recreation areas, public roads and other places are less likely than at home.

A structured online questionnaire was used to obtain information from 3520 postmenopausal women aged 55-65 years living in Great Britain, the United States, Canada, Sweden, Denmark, Finland, and Norway. In total, 45% of women reported experiencing vaginal symptoms. Only 4% of women attributed these symptoms to vaginal atrophy, and 63% failed to recognize vaginal atrophy as a chronic condition. Overall, 44% of respondents did not have a gynecologist, but this percentage varied between countries. Most women (75%) felt that vaginal atrophy had a negative impact on life, but this perception also showed country-specific differences. Most Finnish respondents (76%) were satisfied with the amount of information available about vaginal atrophy, compared with just 37-42% of women from other countries. Most women used over-the-counter products for vaginal atrophy symptoms, but specific means of treating the underlying cause were less well known. Almost half (46%) of all respondents lacked knowledge about local estrogen therapy, with women in Great Britain, the United States and Canada being most likely to lack knowledge of such treatment. Overall, 30% of women would consider taking local estrogen therapy, with vaginal tablets being the preferred option in all countries. Postmenopausal women have a low understanding of vaginal atrophy. Medical practitioners should proactively raise this topic, help patients to understand that vaginal atrophy is a chronic condition, and discuss treatment options. Country-specific approaches may be required.

    Web-based interventions for smoking cessation available in Portuguese do not adhere to evidence-based treatment guidelines. Besides, all existing web-based interventions are built on proprietary platforms that developing countries often cannot afford. We aimed to describe the development of "Viva sem Tabaco", an open-source web-based intervention. The development of the intervention included the selection of content from evidence-based guidelines for smoking cessation, the design of the first layout, conduction of 2 focus groups to identify potential features, refinement of the layout based on focus groups and correction of content based on feedback provided by specialists on smoking cessation. At the end, we released the source-code and intervention on the Internet and translated it into Spanish and English. The intervention developed fills gaps in the information available in Portuguese and the lack of open-source interventions for smoking cessation. The open-source licensing format and its translation system may help researchers from different countries deploying evidence-based interventions for smoking cessation.

    Maternal smoking during pregnancy is associated with low fetal growth and adverse cardiometabolic health in offspring. However, hormonal pathways underlying these associations are unclear. Therefore, we examined maternal smoking habits and umbilical cord blood hormone profiles in a large, prospective cohort. We studied 978 mother/infant pairs in Project Viva, a Boston-area cohort recruited 1999-2002. We categorized mothers as early pregnancy smokers, former smokers, or never smokers. Outcomes were cord blood concentrations of IGF-1, IGF-2, IGFBP-3, leptin, adiponectin, insulin, and C-peptide. We used linear regression models adjusted for maternal pre-pregnancy body mass index (BMI), race/ethnicity, parity, education, and infant sex. We conducted analyses in the full cohort and stratified by infant sex. Thirteen percent of women were early pregnancy smokers, 20% former smokers, and 68% never smokers. Infants of early pregnancy smokers had lower IGF-1 adjusted for IGFBP-3 [-5.2ng/mL (95% CI: -8.6, -1.7)], with more pronounced associations in girls [-10.7ng/mL (95% CI: -18.5, -2.9) vs. -4.0ng/mL (95% CI: -8.4, 0.4) for boys]. Early pregnancy smoking was not associated with cord blood hormones other than IGF-1. Infants of former smokers had a cord blood hormone profile similar to infants of never smokers. As compared to mothers who never smoked, early pregnancy smokers had infants with lower cord blood IGF-1 which could prime adverse metabolic outcomes. This provides further reason to support smoking cessation programs in women of reproductive age. Copyright © 2017 Elsevier Inc. All rights reserved.

    Despite the high prevalence of overweight among Hispanic children in the United States, definitive predictors of weight gain have not been identified in this population. The study objective was to test sociodemographic, metabolic, and behavioral predictors of 1-y weight gains in a large cohort of Hispanic children studied longitudinally. Subjects (n = 879) were siblings from 319 Hispanic families enrolled in the Viva la Familia Study. Families were required to have at least one overweight child aged 4-19 y. One-year changes in weight and body composition by dual-energy X-ray absorptiometry were measured. Data were from parental interviews, birth certificates, multiple-pass 24-h dietary recalls, 3-d accelerometry, 24-h respiration calorimetry, measurements of eating in the absence of hunger, and measurement of fasting blood biochemistry indexes by radioimmunoassay. Generalized estimating equations and principal component analysis were applied. Weight gain increased with age (P = 0.001), peaking at approximately 10 y of age in girls and approximately 11 y of age in boys. Mean (+/-SD) weight gain was significantly higher in overweight (7.5 +/- 3.7 kg/y) than in nonoverweight (4.4 +/- 2.4 kg/y) children and in boys than in girls. When adjusted for age, age squared, sex, and Tanner stage, the final model indicated a child's body mass index (BMI; kg/m2) status, maternal BMI, energy expenditure (total energy expenditure, basal metabolic rate, and sleeping metabolic rate), and fasting blood biochemistry indexes (total triiodothyronine, insulin, leptin, and ghrelin) as independent, positive predictors of weight gain (P = 0.01-0.001). Knowledge of the metabolic and behavioral predictors of weight gain in Hispanic children will inform prevention and treatment efforts to address this serious public health problem in the United States.

    Reduced renal excretion of uric acid plays a significant role in the development of hyperuricemia and gout in adults. Hyperuricemia has been associated with chronic kidney disease and cardiovascular disease in children and adults. There are limited genome-wide association studies associating genetic polymorphisms with renal urate excretion measures. Therefore, we investigated the genetic factors that influence the excretion of uric acid and related indices in 768 Hispanic children of the Viva La Familia Study. We performed a genome-wide association analysis for 24-h urinary excretion measures such as urinary uric acid/urinary creatinine ratio, uric acid clearance, fractional excretion of uric acid, and glomerular load of uric acid in SOLAR, while accounting for non-independence among family members. All renal urate excretion measures were significantly heritable (p <2 × 10(-6)) and ranged from 0.41 to 0.74. Empirical threshold for genome-wide significance was set at p <1 × 10(-7). We observed a strong association (p < 8 × 10(-8)) of uric acid clearance with a single nucleotide polymorphism (SNP) in zinc finger protein 446 (ZNF446) (rs2033711 (A/G), MAF: 0.30). The minor allele (G) was associated with increased uric acid clearance. Also, we found suggestive associations of uric acid clearance with SNPs in ZNF324, ZNF584, and ZNF132 (in a 72 kb region of 19q13; p <1 × 10(-6), MAFs: 0.28-0.31). For the first time, we showed the importance of 19q13 region in the regulation of renal urate excretion in Hispanic children. Our findings indicate differences in inherent genetic architecture and shared environmental risk factors between our cohort and other pediatric and adult populations.

    Genetic and environmental contributions to childhood obesity are poorly delineated. The Viva la Familia Study was designed to genetically map childhood obesity and its comorbidities in the Hispanic population. The objectives of this report were to describe the study design and to summarize genetic and environmental contributions to the phenotypic variation in obesity and risk factors for metabolic diseases in Hispanic children. The Viva la Familia cohort consisted of 1030 children from 319 families selected based on an overweight proband between the ages of 4 and 19 y. In-depth phenotyping to characterize the overweight children and their siblings included anthropometric and body-composition traits by dual-energy X-ray absorptiometry and assessments of diet by 24-h recalls, physical activity by accelerometry, and risk factors for metabolic diseases by standard biochemical methods. Univariate quantitative genetic analysis was used to partition phenotypic variance into additive genetic and environmental components by using the computer program SOLAR. Sex, age, and environmental covariates explained 1-91% of the phenotypic variance. Heritabilities of anthropometric indexes ranged from 0.24 to 0.75. Heritability coefficients for the body-composition traits ranged from 0.18 to 0.35. Diet and physical activity presented heritabilities of 0.32 to 0.69. Risk factors for metabolic diseases were heritable with coefficients ranging from 0.25 to 0.73. Significant genetic correlations between obesity traits and risk factors for metabolic diseases substantiated pleiotropy between traits. The Viva la Familia Study provides evidence of a strong genetic contribution to the high prevalence of obesity and its comorbidities in Hispanic children.

    Objective To assess the safety of VivaGel® used vaginally twice daily for 14 days among healthy, sexually-abstinent women, aged 18–24 years in the USA and Kenya. Design Randomized placebo controlled trial. Methods Participants were randomized 2∶1, VivaGel to placebo. Safety was assessed by comparing genitourinary (GU) adverse events (AEs), colposcopy findings, vaginal lactobacilli and laboratory abnormalities by arm. Results Fifty-four women were enrolled; 35 in the VivaGel arm and 19 in the placebo arm. Twenty-six (74%) and 10 (53%) women reported taking all doses of VivaGel and placebo, respectively. No grade 3 or 4 AEs, or serious AEs occurred. Twenty-five (71%) participants in the VivaGel arm compared to 10 (53%) participants in the placebo arm had at least one grade 1 or 2 GU AE associated with product use (RR = 1.4, 95% CI 0.8-2.2). All seven grade 2 GU AEs associated with product use occurred among four women in the VivaGel arm. Vulvar and cervical erythema, cervical lesions, symptomatic BV, urinary frequency and metrorrhagia were more common in the VivaGel arm than the placebo arm. Twenty-nine (83%) participants in the VivaGel arm had a colposcopic finding compared to 10 (53%) participants in the placebo arm (RR = 1.6, 95%CI = 1.0-2.5). Two women in the VivaGel arm prematurely discontinued product use themselves due to a reported GU AE. Persistence of H2O2-producing and non-producing lactobacilli did not differ by study arm. Conclusions GU AEs and colposcopic findings consistent with mild epithelial irritation and inflammation occurred more commonly among women in the VivaGel arm.

    We compared results of written assessment of intensive care trainees' procedural skills with results obtained from one of two live assessment formats for the purposes of assessing the concurrent validity of the different test methods. Forty-five Australasian senior trainees in intensive care medicine completed a written test relating to a procedural skill, as well as either a simulation format or oral viva assessment on the same procedural skill. We analysed correlation between written exam results and results obtained from simulation format or oral viva assessment. For those who completed the simulation format examination, we also maintained a narrative of actions and identified critical errors. There was limited correlation between written exam results and live (simulation or viva) procedure station results (r = 0.31). Correlation with written exam results was very low for simulation format assessments (r = 0.08) but moderate for oral viva format assessment (r = 0.58). Participants who passed a written exam based on management of a blocked tracheostomy scenario performed a number of dangerous errors when managing a simulated patient in that scenario. The lack of correlation between exam formats supports multi-modal assessment, as currently it is not known which format best represents workplace performance. Correlation between written and oral viva results may indicate redundancy between those test formats, whereas limited correlation between simulation and written exams may support the use of both formats as part of an integrated assessment strategy. We hypothesise that identification of critical candidate errors in a simulation format exam that were not exposed in a written exam may indicate better predictive validity for simulation format examination of procedural skills.

    Data from the Brazilian Surveillance System for Violence and Accidents (VIVA) in 2009 were used to examine socio-demographic characteristics, outcomes, and types of accidents and violence treated at 74 sentinel emergency services in 23 Brazilian State capitals and the Federal District. The analysis included 25,201 individuals aged > 20 years (10.1% > 60 years); 89.3% were victims of accidents and 11.9% victims of violence. Hospitalization was the outcome in 11.1% of cases. Compared to the general population, there were more men and non-white individuals among victims of accidents, and especially among victims of violence. As compared to younger adults (20-59 years), accidents and violence against elderly victims showed less association with alcohol, a higher proportion of domestic incidents, more falls and pedestrian accidents, and aggression by family members. Policies for the prevention of accidents and violence should consider the characteristics of these events in the older population.

    There is little scientific evidence that urban upgrading helps improve health or reduce inequities. This article presents the design for the BH-Viva Project, a "quasi-experimental", multiphase, mixed-methods study with quantitative and qualitative components, proposing an analytical model for monitoring the effects that interventions in the urban environment can have on residents' health in slums in Belo Horizonte, Minas Gerais State, Brazil. A preliminary analysis revealed intra-urban differences in age-specific mortality when comparing areas with and without interventions; the mortality rate from 2002 to 2012 was stable in the "formal city", increased in slums without interventions, and decreased in slums with interventions. BH-Viva represents an effort at advancing methodological issues, providing learning and theoretical backing for urban health research and research methods, allowing their application and extension to other urban contexts.

    Objective The aim of this study was to examine the effect of the 3% SPL 7013 gel (VivaGel®) on mucosal immune markers hypothesized to be associated with HIV-1 acquisition. Design Phase 1, placebo-controlled, randomized, double-blind clinical trial was performed in 54 young women in the U.S. and Kenya. Participants used carbopol gel with and without (placebo) SPL 7013 twice daily over 14 days. Cervical specimens were collected for cytokines, chemokines, T-cells, and dendritic cells at day (D) 0, 7, 14, and 21. A negative binomial regression model was used to assess differences between study arms. Results Several mucosal immune parameters were increased in the VivaGel® arm compared to placebo. For cytokines: D 7, IL-6 (p=0.05); D 14, IFN-γ (p=0.03), IL-2 (p=0.04), IL-5 (p=0.003) and IL-10 (p=0.001) were increased. On D 7, CD8+/CD69+ T-cells tended to be increased (p<0.08); limiting analysis to visits without blood or bacterial vaginosis, these findings were stronger: at D7, CD8+/CD69+ T-cells were increased in the VivaGel® arm (p<0.005), as were CD4+/CD69+ cells (p=0.001) and CD4+/CCR5+ T-cells (p=0.01). The changes described for D7 and 14 were no longer seen at D21. Conclusion Markers associated with inflammation and epithelial damage were reversibly elevated in the VivaGel® arm compared to the placebo arm after 7–14 days of twice daily product use.

    Background Influences of prenatal and early-life exposures to air pollution on cognition are not well understood. Objectives We examined associations of gestational and childhood exposure to traffic-related pollution with childhood cognition. Methods We studied 1,109 mother–child pairs in Project Viva, a prospective birth cohort study in eastern Massachusetts (USA). In mid-childhood (mean age, 8.0 years), we measured verbal and nonverbal intelligence, visual motor abilities, and visual memory. For periods in late pregnancy and childhood, we estimated spatially and temporally resolved black carbon (BC) and fine particulate matter (PM2.5) exposures, residential proximity to major roadways, and near-residence traffic density. We used linear regression models to examine associations of exposures with cognitive assessment scores, adjusted for potential confounders. Results Compared with children living ≥ 200 m from a major roadway at birth, those living < 50 m away had lower nonverbal IQ [–7.5 points; 95% confidence interval (CI): –13.1, –1.9], and somewhat lower verbal IQ (–3.8 points; 95% CI: –8.2, 0.6) and visual motor abilities (–5.3 points; 95% CI: –11.0, 0.4). Cross-sectional associations of major roadway proximity and cognition at mid-childhood were weaker. Prenatal and childhood exposure to traffic density and PM2.5 did not appear to be associated with poorer cognitive performance. Third-trimester and childhood BC exposures were associated with lower verbal IQ in minimally adjusted models; but after adjustment for socioeconomic covariates, associations were attenuated or reversed. Conclusions Residential proximity to major roadways during gestation and early life may affect cognitive development. Influences of pollutants and socioeconomic conditions on cognition may be difficult to disentangle.

    Clinical reasoning is situation-dependent and case-specific; therefore, assessments incorporating different patient presentations are warranted. The present study aimed to determine the reliability of a multi-station case-based viva assessment of clinical reasoning in an Australian pre-registration osteopathy program using generalizability theory. Students (from years 4 and 5) and examiners were recruited from the osteopathy program at Southern Cross University, Lismore, Australia. The study took place on a single day in the student teaching clinic. Examiners were trained before the examination. Students were allocated to 1 of 3 rounds consisting of 5 10-minute stations in an objective structured clinical examination-style. Generalizability analysis was used to explore the reliability of the examination. Fifteen students and 5 faculty members participated in the study. The examination produced a generalizability coefficient of 0.53, with 18 stations required to achieve a generalizability coefficient of 0.80. The reliability estimations were acceptable and the psychometric findings related to the marking rubric and overall scores were acceptable; however, further work is required in examiner training and ensuring consistent case difficulty to improve the reliability of the examination.

    Injuries and deaths resulting from violence constitute a major public health problem in Brazil. The article aims to describe the profile of calls for violence in emergency departments and emergency Brazilian capitals. This is a descriptive study of Violence and Accident Surveillance System (VIVA), carried out in public emergencies Brazilian cities, from September to November 2014, a total of 4406 calls for aggression. We considered the following categories of analysis: 1) sociodemographic characteristics (gender, age, race / skin color, education, place of residence, vulnerability, alcohol intake); 2) Event feature (probable author, nature and means of aggression); and characteristics of care (getting to the hospital, prior service, evolution). Of the total calls for violence (n = 4406), the highest prevalence was among young people 20-39 years (50.2%), male, black and low education. As for the event characteristics it stands out that 87.8% were physical assaults; 46.3% cut/laceration and 13.7% involved a firearm. The results point to the need to strengthen intersectoral actions to expand the network of care and protection.

    In recent years, the prevalence of hypertension and prehypertension increased markedly among children and adolescents, highlighting the importance of identifying determinants of elevated blood pressure early in life. Low birth weight and rapid early childhood weight gain are associated with higher future blood pressure. However, few studies have examined the timing of postnatal weight gain in relation to later blood pressure, and little is known regarding the contribution of linear growth. We studied 957 participants in Project Viva, an ongoing US prebirth cohort. We examined the relations of gains in body mass index z-score and length/height z-score during 4 early life age intervals (birth to 6 months, 6 months to 1 year, 1 to 2 years, and 2 to 3 years) with blood pressure during mid-childhood (6-10 years) and evaluated whether these relations differed by birth size. After accounting for confounders, each additional z-score gain in body mass index during birth to 6 months and 2 to 3 years was associated with 0.81 (0.15, 1.46) and 1.61 (0.33, 2.89) mm Hg higher systolic blood pressure, respectively. Length/height gain was unrelated to mid-childhood blood pressure, and there was no evidence of effect modification by birth size for body mass index or length/height z-score gain. Our findings suggest that more rapid gain in body mass index during the first 6 postnatal months and in the preschool years may lead to higher systolic blood pressure in mid-childhood, regardless of size at birth. Strategies to reduce accrual of excess adiposity during early life may reduce mid-childhood blood pressure, which may also impact adult blood pressure and cardiovascular health. © 2015 American Heart Association, Inc.

Compared with children living ≥ 200 m from a major roadway at birth, those living < 50 m away had lower nonverbal IQ [-7.5 points; 95% confidence interval (CI): -13.1, -1.9], and somewhat lower verbal IQ (-3.8 points; 95% CI: -8.2, 0.6) and visual motor abilities (-5.3 points; 95% CI: -11.0, 0.4). Cross-sectional associations of major roadway proximity and cognition at mid-childhood were weaker. Prenatal and childhood exposure to traffic density and PM2.5 did not appear to be associated with poorer cognitive performance. Third-trimester and childhood BC exposures were associated with lower verbal IQ in minimally adjusted models; but after adjustment for socioeconomic covariates, associations were attenuated or reversed. Residential proximity to major roadways during gestation and early life may affect cognitive development. Influences of pollutants and socioeconomic conditions on cognition may be difficult to disentangle.

    Limited information exists regarding the association between early-life diet and cardiometabolic risk. Examine associations of dietary inflammatory index (DII) in pregnancy and early childhood (3-5 years) with adiposity, blood pressure and metabolic markers in mid-childhood (6-10 years). Among 992 mother-child pairs from Project Viva, a pre-birth cohort, we examined associations of DII scores with outcomes using multivariable linear regression adjusted for child age and sex and maternal age, BMI, education, parity, smoking, race and income. Mean (SD) maternal DII in pregnancy was -2.6(1.4) units and in child DII in early childhood was 0.3(0.7). Mean mid-childhood BMI z-score was 0.40(0.98) units. In boys only, DII in early childhood was associated with higher BMIz (adjusted β = 0.16 units per unit DII, 95%CI 0.02, 0.29), waist circumference (0.93 cm; -0.07, 1.92) and skin fold thicknesses (1.12 mm; 0.01, 2.23). Dietary inflammatory index in the highest quartiles during both pregnancy and in early childhood, compared to the lowest quartiles, was associated with higher waist circumference (2.4 cm; 0.14, 4.6) in all children, and BMIz in boys (0.78 units; 0.34, 1.22). Associations with BP and metabolic markers were null. A pro-inflammatory diet in pregnancy and early childhood may promote the development of adiposity. © 2017 World Obesity Federation.

    Elevated concentrations of serum uric acid are associated with increased risk of gout and renal and cardiovascular diseases. Genetic studies in adults have consistently identified associations of solute carrier family 2, member 9 (SLC2A9), polymorphisms with variation in serum uric acid. However, it is not known whether the association of serum uric acid with SLC2A9 polymorphisms manifests in children. The aim was to investigate whether variation in serum uric acid is under genetic influence and whether the association with SLC2A9 polymorphisms generalizes to Hispanic children of the Viva La Familia Study. We conducted a genomewide association study with 1.1 million genetic markers in 815 children. We found serum uric acid to be significantly heritable [h(2) ± SD = 0.45 ± 0.08, P = 5.8 × 10(-11)] and associated with SLC2A9 variants (P values between 10(-16) and 10(-7)). Several of the significantly associated polymorphisms were previously identified in studies in adults. We also found positive genetic correlations between serum uric acid and BMI z score (ρG = 0.45, P = 0.002), percentage of body fat (ρG = 0.28, P = 0.04), fat mass (ρG = 0.34, P = 0.02), waist circumference (ρG = 0.42, P = 0.003), and waist-to-height ratio (ρG = 0.46, P = 0.001). Our results show that variation in serum uric acid in Hispanic children is under considerable genetic influence and is associated with obesity-related phenotypes. As in adults, genetic variation in SLC2A9 is associated with serum uric acid concentrations, an important biomarker of renal and cardiovascular disease risk, in Hispanic children. © 2015 American Society for Nutrition.

    O conteúdo desse texto surgiu de uma apresentação de mesmo título que fiz na XXXI Reunião Anual da Sociedade Astronômica Brasileira (SAB) em 2005. Esse tema foi inspirado originalmente pela minha participação no "2nd UIPAP International Conference on Women in Physics" realizado entre 23 e 25 de maio de 2005 no Rio de Janeiro. Essa é uma conferência internacional que acontece de três em três anos, sendo que a primeira ocorreu em 2002 na cidade de Paris, França. Participei dessa conferência como membro da delegação da Sociedade Brasileira de Física e um dos trabalhos que apresentei versava sobre a situação das mulheres na Astronomia brasileira, cujos resultados principais discorro a seguir. A situação das astrônomas, baseada nos dados dos sócios da SAB coletados no final de 2004, é comparada com a das físicas brasileiras e também com as nossas colegas americanas. Os dados identificam ainda uma maior evasão da carreira por parte das mulheres do que os homens. Alguns dos possíveis motivos da evasão são discutidos, como o desejo de constituir família e/ou isolamento. Resultados um tanto preocupantes com relação à distribuição de bolsas de produtividade do CNPq também são apresentados. As principais discussões e estratégias recomendadas nesse congresso são mencionadas de forma resumida ao final.

    We present the results of a new VLA H I Imaging survey of Virgo galaxies, the VLA Imaging survey of Virgo galaxies in Atomic gas (VIVA). The survey includes high-resolution H I data of 53 carefully selected late type galaxies (48 spirals and five irregular systems). The goal is to study environmental effects on H I gas properties of cluster galaxies to understand which physical mechanisms affect galaxy evolution in different density regions, and to establish how far out the impact of the cluster reaches. As a dynamically young cluster, Virgo contains examples of galaxies experiencing a variety of environmental effects. Its nearness allows us to study each galaxy in great detail. We have selected Virgo galaxies with a range of star formation properties in low to high density regions (at projected distances from M87, d {sub 87} = 0.3-3.3 Mpc). Contrary to previous studies, more than half of the galaxies in the sample ({approx}60%) are fainter than 12 mag in B{sub T} . Overall, the selected galaxies represent the late type Virgo galaxies (S0/a to Sd/Irr) down to m{sub p} {approx}< 14.6 fairly well in morphological type, systemic velocity, subcluster membership, H I mass, and deficiency. The H I observations were done in C short (CS) configuration of the VLA radio telescope, with a typical spatial resolution of 15'' and a column density sensitivity of {approx}3-5 x 10{sup 19} cm{sup -2} in 3{sigma} per 10 km s{sup -1} channel. The survey was supplemented with data of comparable quality from the NRAO archive, taken in CS or C configuration. In this paper, we present H I channel maps, total intensity maps, velocity fields, velocity dispersions, global/radial profiles, position-velocity diagrams and overlays of H I/1.4 GHz continuum maps on the optical images. We also present H I properties such as total flux (S {sub HI}), H I mass (M {sub HI}), linewidths (W{sub 20} and W{sub 50}), velocity (V{sub HI}), deficiency (def{sub HI}), and size (D {sup eff}{sub HI} and D {sup

    Geoscience education is key for the understanding of our home, the planet Earth. The Lagos Ciência Viva Science Centre (CCVL) in Portugal develops various geoscience activities including astronomy sessions, geology, paleontology and oceanography field trips, complementary primary school classes, seminars and numerous workshops for a public ranging from pre-schoolers to seniors . Our experience in geoscience communication and informal education also includes a formal partnership with a research centre from the University of the Algarve, the CIMA - Centre for Marine and Environmental Research, through the project MOSES, which focuses on sand transport along crenulated coasts. Based on the project goals, methods and results, the CCVL team designed a communication and outreach plan including a seminar, a field trip and a workshop, to alert for the subjects of coastal erosion and management, both highly relevant in the Algarve. This partnership was highly beneficial for both parts as it facilitated the communication of a scientific project to the public, while the CCVL had the opportunity to update and expand its educational offer. This type of interaction between universities/research institutes and science centres/museums allows scientists to focus on their research work, reducing their need to invest in communication, and provides good and updated scientific contents to science communicators, ensuring a direct channel between scientific research and the public.

    This study was conducted to investigate genetic influence on serum ghrelin and its relationship with adiposity-related phenotypes in Hispanic children (n=1030) from the Viva La Familia study (VFS). Anthropometric measurements and levels of serum ghrelin were estimated and genetic analyses conducted according to standard procedures. Mean age, body mass index (BMI), and serum ghrelin were 11+/-0.13 y, 25+/-0.24 kg/m2 and 38+/-0.5 ng/mL, respectively. Significant heritabilities (p<0.001) were obtained for BMI, weight, fat mass, percent fat, waist circumference, waist-to-height ratio, and ghrelin. Bivariate analyses of ghrelin with adiposity traits showed significant negative genetic correlations (p<0.0001) with weight, BMI, fat mass, percent fat, waist circumference, and waist-to-height ratio. A genome-wide scan for ghrelin detected significant linkage on chromosome 1p36.2 between STR markers D1S2697 and D1S199 (LOD=3.2). The same region on chromosome 1 was the site of linkage for insulin (LOD=3.3), insulinlike growth factor binding protein 1 (IGFBP1) (LOD=3.4), homeostatic model assessment method (HOMA) (LOD=2.9), and C-peptide (LOD=2.0). Several family-based studies have reported linkages for obesity-related phenotypes in the region of 1p36. These results indicate the importance of this region in relation to adiposity in children from the VFS.

    The role of diet quality and nutrient adequacy in the etiology of childhood obesity is poorly understood. The specific aims of these analyses were to assess overall diet quality and nutrient adequacy, and test for association between weight status and diet in children from low socioeconomic status (SES) Hispanic families at high risk for obesity. A cross-sectional study design was used to assess dietary intake in low-SES Hispanic children with and without overweight who were enrolled in the Viva la Familia Study. Multiple-pass 24-hour dietary recalls were recorded on two random, weekday occasions. Diet quality was evaluated according to the Dietary Guidelines for Americans. Nutrient adequacy was assessed using z scores based on estimated average requirement or adequate intake. The study included 1,030 Hispanic children and adolescents, aged 4 to 19 years, in Houston, TX, who participated between November 2000 and August 2004. STATA software (version 9.1, 2006, STATA Corp, College Station, TX) was used for generalized estimating equations and random effects regression. Diet quality did not adhere to the Dietary Guidelines for Americans for fat, cholesterol, saturated fatty acids, fiber, added sugar, and sodium. Although energy intake was significantly higher in children with overweight, food sources, diet quality, macro- and micronutrient composition were similar between non-overweight and overweight children. Relative to estimated average requirements or adequate intake levels, mean nutrient intakes were adequate (70% to 98% probability) in the children without and with overweight, except for vitamins D and E, pantothenic acid, calcium, and potassium, for which z scores cannot be interpreted given the uncertainty of their adequate intake levels. Whereas the diets of low-SES Hispanic children with and without overweight were adequate in most essential nutrients, other components of a healthful diet, which promote long-term health, were suboptimal.

    Objective The role of diet quality and nutrient adequacy in the etiology of childhood obesity is poorly understood. The specific aims of these analyses were to 1) assess overall diet quality and nutrient adequacy, and 2) test for association between weight status and diet in children from low socioeconomic status (SES) Hispanic families at high risk for obesity. Design A cross-sectional study design was used to assess dietary intake in low-SES non-overweight and overweight Hispanic children enrolled in the VIVA LA FAMILIA Study. Multiple-pass 24-h dietary recalls were recorded on two random, weekday occasions. Diet quality was evaluated according to United States (US) Dietary Guidelines. Nutrient adequacy was assessed using z-scores based on estimated average requirement (EAR) or adequate intake (AI). Subjects/Setting The study included 1030 Hispanic children and adolescents, ages 4-19 y, in Houston, Texas who participated between November 2000 and August 2004. Statistical analysis STATA was used for generalized estimating equations and random effects regression. Results Diet quality did not adhere to US dietary guidelines for fat, cholesterol, saturated fatty acids, fiber, added sugar and sodium. Although energy intake was significantly higher in overweight children, food sources, diet quality, macro- and micronutrient composition were similar between non-overweight and overweight children. Relative to EAR or AI, mean nutrient intakes were adequate (70-98% probability) in the non-overweight and overweight children, except for vitamins D and E, pantothenic acid, calcium and potassium for which z-scores cannot be interpreted given the uncertainty of their AI's. Conclusion While the diets of low-SES, non-overweight and overweight Hispanic children were adequate in most essential nutrients, other components of a healthy diet, which promote long-term health, were suboptimal.

  10. Assessing the quality of a scientific journal: the case of Revista Brasileira de Psiquiatria.

    PubMed

    Kieling, Christian; Gonçalves, Renata Rocha Fernandes

    2007-06-01

    Scientific production in the field of Psychiatry is growing exponentially, as reflected by the number of scientific journals now available. Current strategies to objectively estimate the quality of a specific publication are mostly based on indexation and citation criteria. The concept of impact factor, a measure of the frequency with which an article has been cited in a particular period, is key to understanding the way journals are evaluated. The recent indexation of Revista Brasileira de Psiquiatria in the two major medical databases has increased the journal's visibility, as indicated by the rising number of citations received over the last years. As researchers' scientific productivity measures are largely associated with citation indices of journals in which manuscripts are published, it is essential that Revista Brasileira de Psiquiatria continues to attract high quality, innovative articles, with the ultimate goal of providing state-of-the-art continuing medical education for mental health professionals.

    The scope of this study is to analyze the differences in the profile of emergency care for external causes between public and private emergency departments. With data come from VIVA-Campinas 2009, the association between the nature of healthcare and the characteristics of the victims was verified using the chi-square test. Using Poisson regression, proportion ratios of care in the public and private network were estimated. In the sample of 1094 victims, 67.8% were treated by public health. Traffic accidents, animal-related accidents, and assaults were 2 times higher in public units, whereas collisions with objects and sprains were 75% and 2.7 times higher in private units. Cranium-encephalic trauma/polytrauma and cuts/lacerations were 3.8 times and 61% more frequent in public care, while victims with no injuries, with dislocations/sprains or fractures being predominant in private care. Head and multiple organ injuries, road accident and work-related injuries, the use of public transport or mobile emergency care services/ambulances were predominant in public care. Revealing significant differences in care in public and private care can contribute to the organization of healthcare.

    The inquiry of this study is the beliefs related to the nursing professional in the first decades of this activity in Brazil. The investigation presupposes that some of these beliefs are still current. The objective is to point out the beliefs expressed by Revista Brasileira de Enfermagem (Brazilian Journal of Nursing) in 33 articles, during the period between 1932 (when the journal was created) and 1954. Five notions of the nursing professional were identified through the analyses of the symbology presented on the cover of the periodical--Egyptian mythology; ideal, science and art, inscribed in a triangle. The categories established for nurses were: self-forgetful, heroine, socially committed, mercenary and bad angel. Finally, the study proposes an interpretation to the ideas presented in the triangle.

    Adequate fruit and vegetable (F&V) intake is important for disease prevention. Yet, most Americans, especially low-income and racial/ethnic minorities, do not eat adequate amounts. These disparities are partly attributable to food environments in low-income neighborhoods where residents often have limited access to affordable, healthful food and easy access to inexpensive, unhealthful foods. Increasing access to affordable healthful food in underserved neighborhoods through mobile markets is a promising, year-round strategy for improving dietary behaviors and reducing F&V intake disparities. However, to date, there have been no randomized controlled trials studying their effectiveness. The objective of the 'Live Well, Viva Bien' (LWVB) cluster randomized controlled trial is to evaluate the efficacy of a multicomponent mobile market intervention at increasing F&V intake among residents of subsidized housing complexes. One housing complex served as a pilot site for the intervention group and the remaining 14 demographically-matched sites were randomized into either the intervention or control group. The intervention group received bimonthly, discount, mobile, fresh F&V markets in conjunction with a nutrition education intervention (two F&V campaigns, newsletters, DVDs and cooking demonstrations) for 12 months. The control group received physical activity and stress reduction interventions. Outcome measures include F&V intake (measured by two validated F&V screeners at baseline, six-month and twelve-months) along with potential psychosocial mediating variables. Extensive quantitative and qualitative process evaluation was also conducted throughout the study. Modifying neighborhood food environments in ways that increase access to affordable, healthful food is a promising strategy for improving dietary behaviors among low-income, racial and ethnic minority groups at increased risk for obesity and other food-related chronic diseases.

    Summary Aim: The purpose of this article is to present the results of a private cardiac surgical practice. This information could also serve as a hermeneutical text for new wisdom. Methods: A personal database of 1 750 consecutive patients who had had coronary artery bypass graft (CABG) surgery was statistically analysed. Mortality and major morbidity figures were compared with large registries. Risk factors for postoperative death were determined. Results: Over a period of 12 years, 1 344 (76.8%) males and 406 (23.2%) females were operated on. The observed mortality rate was 3.03% and the expected mortality rate (EuroSCORE) was 3.87%. After stepwise logistic regression, independent risk factors for death were urgency (intra-aortic balloon pump), renal impairment (chronic kidney disease, stage III), re-operation and an additional procedure. Apart from the 53 deaths, another 91 patients had major complications. Conclusion: Mortality and morbidity rates compared favourably with other international registries. Mortality was related to co-morbidities. This outcome contributes to a hermeneutical understanding focusing on new spiritual wisdom and meaning for the surgeon. PMID:27841902

    The Brazilian Institute for the History of Medicine was founded on 1945 by the physician Ivolino de Vasconcellos. Because the movement intended to be of national scope, the Federação Nacional de História da Medicina e Ciências Afins was also created (National Federation for the History of Medicine and Related Sciences). The latter group had a humanistic understanding of medicine, wherein the history of medicine played a central role; since this subject honored great names and achievements in medicine, members of the federation felt it was a prime tool in the ethical and humanistic training of healthcare professionals. Thus was born the Revista Brasileira de História da Medicina, which fostered scientific and academic production and events in the field of history of medicine and also registered the Federation's activities and scientific output.

    Created in the early 1920s, at a moment when the country's psychiatric field was embracing the preventive outlook, the Liga Brasileira de Higiene Mental included within its members the elite of Brazilian psychiatry, along with a number of physicians and intellectuals. The article discusses the institution's proposals for intervention among children. The league ended up incorporating into its theoretical arsenal the basic themes of mental hygiene and eugenics as part of its general goal of collaborating in Brazil's process of "racial sanitation". With this objective in mind, and viewing the child as a "pre-citizen" who is a "fundamental part within the man of the future", league members included the children's issue in their projects and saw an imperative need for mental health care from early ages on.

    Statistical analysis is necessary for adequate evaluation of the original article by the reader allowing him/her to better visualize and comprehend the results. The objective of the present study was to determine the frequency of the adequate use of statistical tests in original articles published in the Revista Brasileira de Anestesiologia from January 2008 to December 2009. Original articles published in the Revista Brasileira de Anestesiologia between January 2008 and December 2009 were selected. The use of statistical tests was deemed appropriate when the selection of the tests was adequate for continuous and categorical variables and for parametric and non-parametric tests, the correction factor was described when the use of multiple comparisons was reported, and the specific use of a statistical test for analysis of one variable was mentioned. Seventy-six original articles from a total of 179 statistical tests were selected. The frequency of the statistical tests used more often was: Chi-square 20.11%, Student t test 19.55%, ANOVA 10.05%, and Fisher exact test 9.49%. The frequency of the adequate use of statistical tests was 56.42% (95% CI 49.16% to 63.68%), erroneous use in 13.41% (95% CI 8.42% to 18.40%), and an inconclusive result in 30.16% (95% CI 23.44% to 36.88%). The frequency of inadequate use of statistical tests in the articles published by the Revista Brasileira de Anestesiologia between January 2008 and December 2009 was 56.42%.

  4. VIVA: VLA imaging of Virgo galaxies in atomic gas

    NASA Astrophysics Data System (ADS)

    Chung, Aeree

    In this thesis I present high resolution HI maps and kinematics of 53 carefully selected galaxies in the Virgo cluster. The goal is to study details of the cluster environmental effect on galaxy evolution, i.e. in which density regions and by which processes do galaxies feel the impact of the cluster. Studying HI content is essential to achieve this goal as it is often a useful probe of both gas-gas and tidal interactions and also a reservoir of star formation. Virgo as a dynamically young and nearby cluster, it contains many candidates for various mechanisms at work (e.g. ram-pressure or turbulent/viscous stripping, thermal evaporation, and tidal interactions) and allows us to see the details. We have sampled 48 spirals and 5 irregular/dwarf systems which show a wide range of star formation properties from anemic to starburst. The galaxies in the sample are spread throughout the cluster from near the dense cluster core to the outskirts (0.3--3.3 Mpc in projection). The result has revealed a whole spectrum of gas stripping stages from severely HI stripped galaxies to the HI as it is leaving the disk. Most HI stripped but optically undisturbed galaxies are found within 0.5 Mpc radius in projection from the cluster center. These galaxies show signatures of ongoing interactions with the hot cluster gas. Galaxies with truncated HI disks are also found at lower density regions. Some of those might have gone through the cluster core a while ago and currently be in their way out. Some however show gas stripping epochs that is inconsistent with their locations within the cluster which requires more than a simple interaction with static cluster gas; such as tidal interactions with other galaxies or locally enhanced ram-pressure due to subclusters' falling in. Beyond this region, most galaxies show normal (.08 < or = [Special characters omitted.] < 1.2) to extended ([Special characters omitted.] > or = 1.2) HI disks. Especially, 7 galaxies were found with one-sided long Hi tails in intermediate to low density regions (0.6--1.0 Mpc in projection from the cluster center). Their HI distribution and kinematics are suggestive of current/recent stripping (within < 2 × 10 8 yrs before/after the peak pressure clue to the cluster gas). We argue that these galaxies are recent arrivals, falling into the cluster for the first time. It seems that galaxies already feel the cluster impact far out from the cluster center, by losing some gas in the outer disk through interactions with the cluster gas or tidal interactions with neighbors, or combinations of both.

    A Olimpíada Brasileira de Astronomia (OBA) contou, em sua quinta edição, com a participação de mais de 60 mil alunos dos ensinos fundamental e médio de praticamente todo o território nacional. Uma das formas de controle que a sua coordenação nacional possui sobre a correção, levada a cabo pelos professores que as aplicaram, é a do envio, por parte destes professores, das 10 melhores provas de cada um dos três níveis nos quais a Olimpíada é realizada. Assim, e dado ao caráter discursivo das provas da Olimpíada, a sua coordenação nacional dispõe de um vasto acervo sobre as concepções, certas ou erradas, dos alunos que dela participaram. Este conjunto de dados jamais fora explorado até o presente trabalho que pretende ser, neste sentido, inaugural. Nas provas dos níveis I e II da V OBA, que abrangem todo o conjunto do ensino fundamental, uma das questões versava sobre a noção que os alunos tinham sobre como os habitantes da Terra situam-se sobre sua superfície. Fizemos um estudo sistemático das respostas a esta questão. Primeiramente, todas as modalidades de erros foram levantadas; em seguida, realizamos uma distribuição por idade tanto do índice de acerto como da ocorrência e da distribuição de cada erro. Como resultado, obtivemos que, em ambos os níveis: 1) as concepções errôneas não se apresentam distribuídas aleatoriamente; 2) há uma concentração no tipo de erro apresentado; 3) há uma tendência de progressivo acerto com relação à idade quando os dados são considerados em termos nacionais; 4) esta tendência nacional é fraca ou mesmo não é verificada em alguns dos estados com maior patamar de acerto.

  11. Quam bene vivas referre: curing and caring in psycho-oncology.

    PubMed

    Grassi, Luigi

    2013-08-01

    By examining the medical-philosophical Latin heritage, some psycho-oncology principles may be traced in Claudius Galenus and Lucius Anneus Seneca. The former hypothesized a link between depression and cancer; the latter strongly underlined the need for not wasting time, living in the present by searching for meaning and reaching well-being of the soul through virtues, even when dealing with misfortune and negative life events. On these premises, what follows here is an analysis of the first steps in the science of psychosocial care in cancer starting with the work of Arthur M. Sutherland and moving on to more recent psycho-oncology research, which has shown the centrality of a biopsychosocial approach in cancer integrating cure and care (within the double meaning of the old Latin noun cura). Studies of the biopsychosocial approach covering the psychological implications of cancer (e.g., prevalence of emotional distress, application of DSM/ICD classical, and more recent psychiatric classification systems), their psychobiological concomitants (e.g., inflammation and immune dysregulation mechanisms in depression and chronobiology of stress and cancer), and interpersonal issues (e.g., doctor-patient communication and role of neuron mirror system) are discussed. Psychosocial oncology avoids the distinction between curing and caring and includes science and compassion in a whole approach to the multidimensionality of the human being in balancing evidence-based with person-centered/narrative-based oncology (values-based oncology).

    2017-04-01

    We investigate the orbital histories of Virgo galaxies at various stages of H i gas stripping. In particular, we compare the location of galaxies with different H i morphology in phase space. This method is a great tool for tracing the gas stripping histories of galaxies as they fall into the cluster. Most galaxies at the early stage of H i stripping are found in the first infall region of Virgo, while galaxies undergoing active H i stripping mostly appear to be falling in or moving out near the cluster core for the first time. Galaxies with severely stripped, yet symmetric, H i disks are found in one of two locations. Some are deep inside the cluster, but others are found in the cluster outskirts with low orbital velocities. We suggest that the latter group of galaxies belong to a “backsplash” population. These present the clearest candidates for backsplashed galaxies observationally identified to date. We further investigate the distribution of a large sample of H i-detected galaxies toward Virgo in phase space, confirming that most galaxies are stripped of their gas as they settle into the gravitational potential of the cluster. In addition, we discuss the impact of tidal interactions between galaxies and group preprocessing on the H i properties of the cluster galaxies, and link the associated star formation evolution to the stripping sequence of cluster galaxies.

  1. Viva La Ciencia: Cuba’s Creative Scientists Aim to Make Knowledge Their Country’s Sugar Substitute

    NASA Astrophysics Data System (ADS)

    Reid, Rosalind; Hayes, Brian

    At first, peas served as particles in Ernesto Altshuler's experiment. A mechanical dispenser would drop the chícharos one by one into the space between two glass plates, forming a tidy two-dimensional approximation of a sand pile. Lattice structure appeared, then vanished, as the pile self-organized and went critical—avalanche! But Havana's insects soon found the peas in Altshuler's physics lab. For a physicist working under harsh economic conditions of Cuba in the early 1990s, options were few. Yet Altshuler's solution came as a byproduct of the crisis: Because of fuel shortages, the country had begun importing Chinese bicycles, and ball bearings were available in abundance. Thus the peas have been replaced by steel beads, but Altshuler and his students still call their machine the chícharotron.

  2. Disciplines and Professors of Astronomy in Undergraduate Physics Teachers Formation Courses in Brazilian Universities.

    2014-12-01

    This article is the result of a research on basic training in Astronomy in physics degrees that performed the ENADE 2011 national examination. The objective was to identify whether there are disciplines of Astronomy in these courses, whether are mandatory or optional, its workload and when it is offered. The relationship between astronomers, physics degrees and disciplines of Astronomy was investigated. To perform this research we examined the results of ENADE 2011 and also the census of Brazilian Astronomical Society. As a result it is observed that in only 15% of the courses there is a mandatory subject of Astronomy, and therefore there is a high probability that 85% of physics teachers trained in 2011 have not had any discipline of Astronomy during their graduation. In addition, the data collected in this study shows a low number of members of SAB (Sociedade Astronômica Brasileira) among the surveyed courses. We have verified that the presence of astronomers in a given university does not imply to have a mandatory discipline of Astronomy in physics degrees at the same university. Este artículo es el resultado de una investigación sobre la formación básica en Astronomía en los cursos de Profesorado en Física que hicieron el examen nacional ENADE 2011. El objetivo del trabajo fue identificar se existen disciplinas de Astronomía en estos cursos, si son obligatorias u optativas, cuál es su carga horaria y el semestre en que son ofrecidas. Se investigó también la correlación entre astrónomos, los cursos de licenciatura en Física y las disciplinas de Astronomía. Para realizar esta investigación se utilizaron los datos del ENADE 2011 y también del censo de la Astronomía brasileña. Como resultado, se observó que en solo 15% de los cursos existe una disciplina obligatoria de Astronomía y que existe una grande probabilidad de que 85% de los profesores de Física formados en el año de 2011 no hayan cursado ninguna disciplina de Astronomía durante su

    The purpose of this study was to determine whether thin-capped fibroatheromata (TCFA) identified by virtual histology intravascular ultrasound (VH-IVUS) are associated with major adverse cardiac events (MACE) on individual plaque or whole patient analysis. Post-mortem studies have identified TCFA as the substrate for most myocardial infarctions. However, little is known about the natural history of individual TCFA and their link with MACE. VH-IVUS provides a method of identifying plaques in vivo that are similar (although not identical) to histologically defined TCFA, and has been validated in human atherectomy and post-mortem studies. One hundred seventy patients with stable angina or troponin-positive acute coronary syndrome referred for percutaneous coronary intervention (PCI) were prospectively enrolled and underwent 3-vessel VH-IVUS pre-PCI and also post-PCI in the culprit vessel. MACE consisted of death, myocardial infarction, or unplanned revascularization. In all, 30,372 mm of VH-IVUS were analyzed. Eighteen MACE occurred in 16 patients over a median follow-up of 625 days (interquartile range: 463 to 990 days); 1,096 plaques were classified, and 19 lesions resulted in MACE (13 nonculprit lesions and 6 culprit lesions). Nonculprit lesion factors associated with nonrestenotic MACE included VHTCFA (hazard ratio [HR]: 7.53, p = 0.038) and plaque burden >70% (HR: 8.13, p = 0.011). VHTCFA (HR: 8.16, p = 0.007), plaque burden >70% (HR: 7.48, p < 0.001), and minimum luminal area <4 mm(2) (HR: 2.91, p = 0.036) were associated with total MACE. On patient-based analysis, the only factor associated with nonrestenotic MACE was 3-vessel noncalcified VHTCFA (HR: 1.79, p = 0.004). VH-IVUS TCFA was associated with nonrestenotic and total MACE on individual plaque analysis, and noncalcified VHTCFA was associated with nonrestenotic and total MACE on whole-patient analysis, demonstrating that VH-IVUS can identify plaques at increased risk of subsequent events. The preservation of the association between VHTCFA and MACE despite various analyses emphasizes its biological importance. Copyright © 2011 American College of Cardiology Foundation.

  15. Transferências intergeracionais privadas na Amazônia rural brasileira

    What motivates family members to share resources? Past research argues for, on the one hand, love and altruism, and on the other, the expectation of reciprocity. Drawing on this literature, this paper examines intergenerational transfers between small farmers and their non-coresident children in the rural area around the city of Altamira, Pará, Brazil. We apply GoM (Grade of Membership) models to create profiles of private transfers, using data collected in 2005 by a team from Indiana University. The results show three profiles: low intergenerational transfers, high levels of transfers of visits and help, and high levels of transfers of visits and money. There is no clear difference in profile by birth order, but we do find sex differences in profile. Men are more likely to send money while women provide time transfers (work and visits). Upward transfers are most common from children with high levels of education or living in urban areas, suggesting a repayment of prior investments made by parents. Thus, our empirical evidence supports theories arguing that transfers are motivated by intertemporal contracts between parents and children, and that altruistic theories of family transfers should be rethought among rural agricultural populations in contexts characterized by many environmental and institutional challenges.

    Candida infections account for 80% of all fungal infections in the hospital environment, including bloodstream, urinary tract and surgical site infections. Bloodstream infections are now a major challenge for tertiary hospitals worldwide due to their high prevalence and mortality rates. The incidence of candidemia in tertiary public hospitals in Brazil is approximately 2.5 cases per 1000 hospital admissions. Due to the importance of this infection, the authors provide a review of the diversity of the genus Candida and its clinical relevance, the therapeutic options and discuss the treatment of major infections caused by Candida. Each topography is discussed with regard to epidemiological, clinical and laboratory diagnostic and therapeutic recommendations based on levels of evidence. Copyright © 2013 Elsevier Editora Ltda.

    A razão para o desenvolvimento deste trabalho baseia-se no fato de que muitos professores da Educação Básica (EB) não lidam com conceitos relacionados à astronomia, e quando o fazem eles simplesmente seguem livros didáticos que podem conter erros conceituais. Como é de conhecimento geral a astronomia é um dos conteúdos a serem ensinados na EB fazendo parte dos Parâmetros Curriculares Nacionais e das Propostas Curriculares do Estado de São Paulo, mas é um fato, que vários pesquisadores apontam, a existência de muitos problemas no ensino da astronomia. Com o propósito de minimizar algumas dessas deficiências foi realizado um trabalho de pesquisa com a utilização de questionários pré e pós pesquisa, para tanto foi desenvolvido um Curso de Extensão Universitária para professores da Diretoria de Ensino Regional (DE) que abrange Mauá, Ribeirão Pires e Rio Grande da Serra (no Estado de São Paulo) com os seguintes objetivos: levantar concepções alternativas; subsidiar os professores por meio de palestras, debates e workshops, e verificar o sucesso da aprendizagem após o curso, adotando-se como referência, para a análise dos resultados, os dicionários de Língua Portuguesa (FERREIRA, 2004) e Enciclopédico de Astronomia e Astronáutica (MOURĀO, 1995). Portanto, dezesseis questões foram aplicadas antes e após o curso, assim pode-se verificar após a pesquisa que 100,0% dos professores sabiam os nomes das fases da Lua, 97,0% entenderam que o Sistema Solar é composto por oito planetas, 78,1% foram capazes de explicar como ocorre um eclipse lunar, um eclipse solar e um solstício, 72,7% sabiam como explicar a ocorrência das estações do ano; 64,5% explicaram corretamente a ocorrência do equinócio, 89,7% foram capazes de definir adequadamente o termo cometa; 63,6% definiram asteróide, 54,5% meteoro, 58,1% galáxia, e 42,4% planeta. Os resultados obtidos indicam uma aprendizagem significativa por parte dos participantes.

    The Violence and Accidents Survey Conducted in Sentinel Emergency Departments (VIVA Survey) is the sentinel surveillance component of the Violence and Accidents Surveillance System (VIVA). It was conducted for the first time in 2006 and again in 2007, 2009, 2011 and 2014. The sample is comprised of victims of accidents and violence treated in Emergency Departments linked to the Brazilian National Health System (SUS). The services are selected intentionally. This isfollowed by probability sampling of 12-hour shifts by conglomerates in single-stage selection. Data is collected by trained interviewers using a standard form. The variables include data about the service site, the victim, the event, injury and case development. The VIVA Survey provides key information for the implementation of policies for addressing violence and accidents as well as for health and peace promotion policies.

  2. Enhanced dark field microscopy for rapid artifact-free detection of nanoparticle binding to Candida albicans cells and hyphae.

    PubMed

    Weinkauf, Heidi; Brehm-Stecher, Byron F

    2009-06-01

    We surveyed a panel of 13 metal nanoparticle (NP) catalysts for their antifungal activities against Candida albicans ATCC 90028. Initial characterization using scanning electron microscopy (SEM) suggested that our ability to detect NP binding to Candida surfaces with this method was impeded by preparation artifacts. As an alternative method for visualizing NP binding, we used an enhanced dark field illumination system (CytoViva) attached to a standard light microscope. When viewed using this system, all NP produced intense optical signals due to resonant light scattering. To assay binding, NP were allowed to interact with C. albicans hyphae and cells in spent RPMI broth for 15 min with gentle inversion, followed by viewing with the CytoViva system. The antifungal efficacy of NP preparations was determined separately using a 24-h broth microdilution test. For single-metal NP, observations of binding at 15 min made via CytoViva corresponded to antifungal efficacy at 24 h, with the most antifungal NP yielding complete coverage of hyphal surfaces. Our work suggests the utility of visual screening using the CytoViva system for rapid, simple and artifact-free viewing of NP-cell interactions in support of antimicrobial screening efforts. This approach provides a quick and accessible alternative to SEM for imaging of NP-cell interactions.

    Writing a bachelor thesis (BT) is the last step to obtain a nursing degree. In order to perform an effective assessment of a nursing BT, certain reliable and valid tools are required. To develop and validate a 3-rubric system (drafting process, dissertation, and viva) to assess final year nursing students' BT. A multi-disciplinary study of content validity and psychometric properties. The study was carried out between December 2014 and July 2015. Nursing Degree at Universitat Jaume I. Spain. Eleven experts (9 nursing professors and 2 education professors from 6 different universities) took part in the development and content validity stages. Fifty-two theses presented during the 2014-2015 academic year were included by consecutive sampling of cases in order to study the psychometric properties. First, a group of experts was created to validate the content of the assessment system based on three rubrics (drafting process, dissertation, and viva). Subsequently, a reliability and validity study of the rubrics was carried out on the 52 theses presented during the 2014-2015 academic year. The BT drafting process rubric has 8 criteria (S-CVI=0.93; α=0.837; ICC=0.614), the dissertation rubric has 7 criteria (S-CVI=0.9; α=0.893; ICC=0.74), and the viva rubric has 4 criteria (S-CVI=0.86; α=8.16; ICC=0.895). A nursing BT assessment system based on three rubrics (drafting process, dissertation, and viva) has been validated. This system may be transferred to other nursing degrees or degrees from other academic areas. It is necessary to continue with the validation process taking into account factors that may affect the results obtained. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Agriculture is the largest freshwater consumer, accounting for 70% of the world's water withdrawal. Water footprints (WFs) are being increasingly used to indicate the impacts of water use by production systems. A new methodology to assess WF of wine was developed in the framework of the V.I.V.A. project (Valutazione Impatto Viticoltura sull'Ambiente), launched by the Italian Ministry for the Environment in 2011 to improve the Italian wine sector's sustainability. The new methodology has been developed that enables different vines from the same winery to be compared. This was achieved by calculating the gray water footprint, following Tier III approach proposed by Hoekstra et al. (2011). The impact of water use during the life cycle of grape-wine production was assessed for six different wines from the same winery in Sicily, Italy using both the newly developed methodology (V.I.V.A.) and the classical methodology proposed by the Water Footprint Network (WFN). In all cases green water was the largest contributor to WF, but the new methodology also detected differences between vines of the same winery. Furthermore, V.I.V.A. methodology assesses water body contamination by pesticides application whereas the WFN methodology considers just fertilization. This fact ended highlights the highest WF of vineyard 4 calculated by V.I.V.A. if compared with the WF calculated with WFN methodology. Comparing the WF of wine produced with grapes from the six different wines, the factors most greatly influencing the results obtained in this study were: distance from the water body, fertilization rate, amount and eco-toxicological behavior of the active ingredients used.

    We present the results obtained in a research on the comprehension of basic astronomical concepts, in which 561 students from fifth grade middle school to third grade high school of a public school of the city of Foz do Iguaçu (Brazil) took part. A test with 20 multiple-choice questions was applied to indentify the most common conceptions expressed by the students. This test was elaborated based on the literature about misconceptions and covered the following topics: the day-night cycle; the time zones; the seasons of the year; the phases of the Moon; the movement of the Moon; the apparent movement of the Sun in the celestial sphere; the eclipses; the dimensions and distances in the Universe; the brightness of the stars and its observation from Earth. Though a small progress was verified in the proportion of scientifically acceptable answers when comparing the eighth grade of middle school to the fifth, and the third grade of high school to the first, there was an overall predominance of alternative conceptions regarding most of the explored subjects, which persisted up to the last year of secondary school. The comparison to data found in this research made in other socio-cultural contexts revealed, in many aspects, similar notions and difficulties revealed by the students. Se presentan los resultados de una investigación sobre la comprensión de conceptos astronómicos básicos, en la cual participaron 561 estudiantes que cursaban entre el quinto grado de la enseñanza primaria y el tercer año de la enseñanza secundaria de una escuela pública de la ciudad de Foz do Iguaçu (Brasil). Se utilizó un test de 20 preguntas de opción múltiple para identificar las concepciones más comunes expresadas por los estudiantes. Este instrumento de recolección de datos se desarrolló en base a la literatura sobre las concepciones alternativas y trató los siguientes temas: el ciclo día-noche, los husos horarios, las estaciones del año, las fases de la Luna, el movimiento de la Luna, el movimiento aparente del Sol sobre la esfera celeste, los eclipses, las dimensiones y las distancias en el Universo, el brillo de las estrellas y su observación de la Tierra. Si bien ha habido un pequeño progreso en la proporción de respuestas aceptables científicamente cuando se cotejó el octavo grado de la enseñanza primaria con el quinto, y el último año de la enseñanza secundaria con el primero, se observó un predominio de las concepciones alternativas en relación a la mayoría de los temas explorados, que continuó hasta los últimos años de la educación básica.

    Purpose To assess the association between self-reported racial discrimination and prenatal depressive symptoms among black women. Methods Our study population consisted of two cohorts of pregnant women: the Asthma Coalition on Community, Environment, and Social Stress project (ACCESS) and Project Viva. We measured self-reported racial discrimination among black women using a modified Experiences of Discrimination scale (score 0–8). We assessed elevated depressive symptoms (EDS) with the Edinburgh Postnatal Depression Scale (≥13 on a 0–30 scale). Results Fifty-four percent of ACCESS and 78% of Viva participants reported experiencing racial discrimination. After adjusting for age, marital status, income, education, and nativity, a 1-U increment in Experiences of Discrimination score was associated with 48% increased odds of EDS (odds ratio, 1.48; 95% confidence interval, 1.24–1.76) for ACCESS participants but was not significantly associated among Viva participants (odds ratio, 1.12; 95% confidence interval, 0.92–1.37). In both cohorts, responding to unfair treatment by talking to others was associated with the lowest odds of EDS. Conclusions Our findings suggest that higher levels of perceived racial discrimination may increase depressive symptoms during pregnancy among U.S. black women. Interventions involving talking to others may aid in reducing the risk of depressive symptoms among black women experiencing higher levels of racial discrimination. PMID:23123506

    We describe two advanced video analysis techniques, including video-indexed by voice annotations (VIVA) and multi-media indexing and explorer (MINER). VIVA utilizes analyst call-outs (ACOs) in the form of chat messages (voice-to-text) to associate labels with video target tracks, to designate spatial-temporal activity boundaries and to augment video tracking in challenging scenarios. Challenging scenarios include low-resolution sensors, moving targets and target trajectories obscured by natural and man-made clutter. MINER includes: (1) a fusion of graphical track and text data using probabilistic methods; (2) an activity pattern learning framework to support querying an index of activities of interest (AOIs) and targets of interest (TOIs) by movement type and geolocation; and (3) a user interface to support streaming multi-intelligence data processing. We also present an activity pattern learning framework that uses the multi-source associated data as training to index a large archive of full-motion videos (FMV). VIVA and MINER examples are demonstrated for wide aerial/overhead imagery over common data sets affording an improvement in tracking from video data alone, leading to 84% detection with modest misdetection/false alarm results due to the complexity of the scenario. The novel use of ACOs and chat Sensors 2014, 14 19844 messages in video tracking paves the way for user interaction, correction and preparation of situation awareness reports.

  15. Strain-rate Dependence of Elastic Modulus Reveals Silver Nanoparticle Induced Cytotoxicity.

    Force-displacement measurements are taken at different rates with an atomic force microscope to assess the correlation between cell health and cell viscoelasticity in THP-1 cells that have been treated with a novel drug carrier. A variable indentation-rate viscoelastic analysis, VIVA, is employed to identify the relaxation time of the cells that are known to exhibit a frequency dependent stiffness. The VIVA agrees with a fluorescent viability assay. This indicates that dextran-lysozyme drug carriers are biocompatible and deliver concentrated toxic material (rhodamine or silver nanoparticles) to the cytoplasm of THP-1 cells. By modelling the frequency dependence of the elastic modulus, the VIVA provides three metrics of cytoplasmic viscoelasticity: a low frequency modulus, a high frequency modulus and viscosity. The signature of cytotoxicity by rhodamine or silver exposure is a frequency independent twofold increase in the elastic modulus and cytoplasmic viscosity, while the cytoskeletal relaxation time remains unchanged. This is consistent with the known toxic mechanism of silver nanoparticles, where metabolic stress causes an increase in the rigidity of the cytoplasm. A variable indentation-rate viscoelastic analysis is presented as a straightforward method to promote the self-consistent comparison between cells. This is paramount to the development of early diagnosis and treatment of disease.

    Certain per- and polyfluoroalkyl substances (PFASs) are suspected developmental toxicants, but data on PFAS concentrations and exposure routes in children are limited. We measured plasma PFASs in children aged 6-10 years from the Boston-area Project Viva prebirth cohort, and used multivariable linear regression to estimate associations with sociodemographic, behavioral, and health-related factors, and maternal PFASs measured during pregnancy. PFAS concentrations in Project Viva children (sampled 2007-2010) were similar to concentrations among youth participants (aged 12-19 years) in the 2007-8 and 2009-10 National Health and Nutrition Examination Survey (NHANES); mean concentrations of most PFASs declined from 2007 to 2010 in Project Viva and NHANES. In mutually adjusted models, predictors of higher PFAS concentrations included older child age, lower adiposity, carpeting or a rug in the child's bedroom, higher maternal education, and higher neighborhood income. Concentrations of perfluorooctanesulfonate (PFOS), perfluorooctanoate (PFOA), perfluorohexanesulfonate (PFHxS), and 2-(N-methyl-perfluorooctane sulfonamido) acetate (Me-PFOSA-AcOH) were 26-36% lower in children of black mothers compared to children of white mothers and increased 12-21% per interquartile range increase in maternal pregnancy PFASs. Breastfeeding duration did not predict childhood PFAS concentrations in adjusted multivariable models. Together, the studied predictors explained the observed variability in PFAS concentrations to only a modest degree.

  17. Manual resuscitators and portable ventilators.

    This paper reviews the state of the art in Australia of manually operated, self-inflating bag resuscitators, including the Laerdal, Air Viva and Ambu; manually operated bags dependent upon an oxygen supply, including Mapleson B, C, E and F, the CIG Medishield Oxy-Saver and modified Oxy-Viva Resuscitator 3, and the Komesaroff Oxy-Resuscitator RD85; oxygen-powered resuscitators, including the Oxy-Viva Resuscitator 3 with Demand and RM2 Valves, and the Oxylife FM85; and portable ventilators, including the Drager Oxylog, and Ohmeda Logic 07. Specific comment is made to the effect that the design of the resuscitator is often less important than the knowledge and ability of the operator in using the equipment to achieve adequate lung ventilation. The simplest, cheapest, most useful resuscitators are the manually operated self-inflating bag assemblies. With special training, use of more complex equipment can be justified in some circumstances. The more complex the equipment, the greater the risk of inappropriate use, and the greater the risk of equipment malfunction unless a regular maintenance program is followed.

  18. Hypothesis exploration with visualization of variance

    PubMed Central

    2014-01-01

    Background The Consortium for Neuropsychiatric Phenomics (CNP) at UCLA was an investigation into the biological bases of traits such as memory and response inhibition phenotypes—to explore whether they are linked to syndromes including ADHD, Bipolar disorder, and Schizophrenia. An aim of the consortium was in moving from traditional categorical approaches for psychiatric syndromes towards more quantitative approaches based on large-scale analysis of the space of human variation. It represented an application of phenomics—wide-scale, systematic study of phenotypes—to neuropsychiatry research. Results This paper reports on a system for exploration of hypotheses in data obtained from the LA2K, LA3C, and LA5C studies in CNP. ViVA is a system for exploratory data analysis using novel mathematical models and methods for visualization of variance. An example of these methods is called VISOVA, a combination of visualization and analysis of variance, with the flavor of exploration associated with ANOVA in biomedical hypothesis generation. It permits visual identification of phenotype profiles—patterns of values across phenotypes—that characterize groups. Visualization enables screening and refinement of hypotheses about variance structure of sets of phenotypes. Conclusions The ViVA system was designed for exploration of neuropsychiatric hypotheses by interdisciplinary teams. Automated visualization in ViVA supports ‘natural selection’ on a pool of hypotheses, and permits deeper understanding of the statistical architecture of the data. Large-scale perspective of this kind could lead to better neuropsychiatric diagnostics. PMID:25097666

    The methodology and relevance of articles are among the keystones for promoting their citation and increasing journals' impact factors. Study designs appropriate for answering the questions and adequate sample sizes have the aim of reducing the risk of bias. This study evaluated the articles published in two Brazilian journals of orthopedics and sports medicine that were recently indexed in the ISI Web of Science, regarding study design, sample size calculation, randomization and blinding. Descriptive study at Brazilian Cochrane Center. Through a manual search, all original manuscripts published in 2007 in Acta Ortopédica Brasileira and Revista Brasileira de Medicina do Esporte were selected and evaluated. All the 60 articles published in Acta Ortopédica Brasileira and the 87 articles in Revista Brasileira de Medicina do Esporte were included and evaluated. The commonest design in Acta Ortopédica Brasileira was experimental studies (n = 19) and in Revista Brasileira de Medicina do Esporte, update or review articles (n =14). Sample calculations were seen in a minority of the articles. None of the eight clinical trials published presented sample calculations or adequate randomization processes. Three were described as blinded, but none described the measures taken to prevent disclosure of the allocation concealment. Publication of studies of good methodological quality other than review and experimental studies should be strongly encouraged among Brazilian journals, with the aim of increasing their citation and therefore their impact factor.

    Management of the airway of a trauma victim is considered challenging. Various approaches have been described to achieve airway control in this setup; many of them include video-assited viewing of the larynx during intubation. ETView Single Lumen (SL) is a novice single-use endotracheal tube equiped with a video camera and a light source at its distal tip. Its use was previously described in seeral clinical and training setups. The aim was to evaluate the efficacy of the VivaSight SL compared with classic direct laryngoscopy performed with a Macintosh blade in a manikin-simulated trauma setup presenting various degrees of airway challenge when performed by inexperienced physicians. This was prospective, randomized, crossover, manikin trial. After short training on the ETView system, 67 novice paramedics attempted to perform oral intubation using both standard direct laryngoscopy (MAC group) and the VivaSight SL endotracheal tube (ETView group) in a randomized order on manikins in 3 increasingly more difficult scenarios (simple intubation, cervical spine manual stabilization, and with cervical collar in place). Overall success rate, time to intubation, number of intubation attempts, laryngeal view grade, dental compression, and overall participant satisfaction were monitored. Duration of intubation and number of attempts were significantly superior in the ETView group in the latter 2 more challenging scenarios. All other parameters showed superiority to the ETView group in all 3 scenarios. The VivaSight SL system performed better in a complex scenario of airway management of a trauma victim in need for cervical spine stabilization performed by novice caregivers compared to standard direct laryngoscopy and should be considered in this clinical setup.

    The study aims to understand the process and factors influencing the implementation of structured oral examination (SOE) for undergraduate medical students; in comparison with conventional oral examination (COE) in pharmacology. In a randomized, parallel group study, 123 students of pharmacology were divided into two groups, SOE (n = 63) and COE (n = 60). Students of each group were subdivided into two, and four examiners took viva voce individually. Three sets of questionnaires from autonomic nervous system were prepared, each having 15 items with increasing difficulty levels and were validated by subject experts and pretested. Ten minutes were allotted for each student for each viva. Feedback of students and faculty about the novel method was obtained. SOE yielded significantly lower marks as compared to COE. There were significant inter-examiner variations in marks awarded in SOE and COE. Other factors influencing implementation were difficulty in structuring viva, rigid time limits, lack of flexibility in knowledge content, monotony, and fatigue. The students perceived this format not different from COE but felt that it required in-depth preparation of topic. Faculty opined that SOE led to less drift from main topic and provided uniform coverage of topics in given time. Conducting SOE is a resource-intensive exercise. Despite structuring, inter-examiner variability was not completely eliminated. The students' performance was depended on factors related to examiners such as teaching experience, vernacular language used, and lack of training. Orientation and training of examiners in assessment strategies is necessary. Standardization of questionnaire is necessary before the implementation of SOE for summative assessment.

    In adults, adherence to the Mediterranean diet has been inversely associated with cardiovascular risk, but the extent to which diet in pregnancy is associated with offspring adiposity is unclear. We aimed to investigate the association between adherence to Mediterranean diet in pregnancy and offspring cardiometabolic traits in two pregnancy cohorts. We studied 997 mother-child pairs from Project Viva in Massachusetts, USA, and 569 pairs from the Rhea study in Crete, Greece. We estimated adherence to the Mediterranean diet with an a priori defined score (MDS) of nine foods and nutrients (0 to 9). We measured child weight, height, waist circumference, skin-fold thicknesses, blood pressure, and blood levels of lipids, c-reactive protein and adipokines in mid-childhood (median 7.7 years) in Viva, and in early childhood (median 4.2 years) in Rhea. We calculated cohort-specific effects and pooled effects estimates with random-effects models for cohort and child age. In Project Viva, the mean (SD, standard deviation) MDS was 2.7 (1.6); in Rhea it was 3.8 (1.7). In the pooled analysis, for each 3-point increment in the MDS, offspring BMI z-score was lower by 0.14 units (95% CI, -0.15 to -0.13), waist circumference by 0.39 cm (95% CI, -0.64 to -0.14), and the sum of skin-fold thicknesses by 0.63 mm (95% CI, -0.98 to -0.28). We also observed lower offspring systolic (-1.03 mmHg; 95% CI, -1.65 to -0.42) and diastolic blood pressure (-0.57 mmHg; 95% CI, -0.98 to -0.16). Greater adherence to Mediterranean diet during pregnancy may protect against excess offspring cardiometabolic risk. © 2017 World Obesity Federation.

    This paper investigates the feasibility of applying genetic algorithms to solve optimization problems that are implemented entirely in reconfgurable hardware. The paper highlights the pe$ormance/design space trade-offs that must be understood to effectively implement a standard genetic algorithm within a modem Field Programmable Gate Array, FPGA, reconfgurable hardware environment and presents a case-study where this stochastic search technique is applied to standard test-case problems taken from the technical literature. In this research, the targeted FPGA-based platform and high-level design environment was the Starbridge Hypercomputing platform, which incorporates multiple Xilinx Virtex II FPGAs, and the Viva TM graphical hardware description language.

    Human rabies has re-emerged in Latin America due to bat associated transmission. We present data related to attacks by hematophagous bats in three riverine communities in the Rio Negro basin, Brazilian Amazon. A cross-sectional survey was carried out to obtain demographic and epidemiological data through interviews with 201 inhabitants. A total of 721 bat attacks with bites took place from 2004 to 2006, 238 (33%) reported by residents in Campinas do Rio Preto, 329 (46%) in Águas Vivas and 154 (21%) in the community of Malalahá. Incidence density among surveyed inhabitants was 84 attacks/100 persons-years in Campinas do Rio Preto, 249 attacks/100 persons-years in Águas Vivas and 81 attacks/100 persons-years in Malalahá. The proportion of surveyed inhabitants bled by bats at least once was 67% (63/94) in Campinas do Rio Preto, 96% (42/44) in Águas Vivas and 62% (39/63) in Malalahá. Among subjects bled by bats, the average number of bites was 4.6 ± 4.2 standard deviations (SD) in Campinas do Rio Preto, 8 ± 6 SD in Águas Vivas and 4.1 ± 3.9 SD in Malalahá. Regarding houses, 67% (26/39) had animals in the peridomestic environment (chickens and/or dogs) and all were vulnerable to bats due to gaps in the walls and/or in the windows and doors. In 13 dwellings, rudimentary protection against bats through the fixation of fishing nets and/or straw nets to the windows and other openings was observed. Among dwellers reporting attacks, 48% (68/144) received the full post-exposure anti-rabies vaccination protocol with five doses of diploid human cell vaccine, 28% (39/144) received an incomplete schedule (1-4 doses), and 26% (37/144) did not receive any dose. No cases of rabies were reported during the study; however, regular pre-exposure vaccination in the studied populations must be considered.

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

    The article aims to describe the profile of elderly victims of falls and traffic accidents from the data of the Surveillance Survey of Violence and Accidents (VIVA). The VIVA Survey was conducted in the emergency health-services of the Unified Health System in the capitals of Brazil in 2011. The sample of elderly by type of accident was subjected to the two-step cluster procedure. Of the 2463 elderly persons in question, 79.8% suffered falls and 20.2% were the victims of traffic accidents. The 1812 elderly who fell were grouped together into 4 clusters: Cluster 1, in which all had disabilities; Cluster 2, all were non-white and falls took place in the home; Cluster 3, younger and active seniors; and Cluster 4, with a higher proportion of seniors 80 years old or above who were white. Among cases of traffic accidents, 446 seniors were grouped into two clusters: Cluster 1 of younger elderly, drivers or passengers; Cluster 2, with higher age seniors, mostly pedestrians. The main victims of falls were women with low schooling and unemployed; traffic accident victims were mostly younger and male. Complications were similar in victims of falls and traffic accidents. Clusters allow adoption of targeted measures of care, prevention and health promotion.

    The UEMS Otorhinolaryngology-Head and Neck Surgery section is a dedicated body formed to promote the standardisation and harmonisation of European Otorhinolaryngology (ORL). The European Examination Board of Otorhinolaryngology and Head and Neck Surgery was created to establish a supranational final exam and accreditation for ORL Surgeons. It is open to candidates both from the European Union and outside the EU. The exam is composed of a written examination to assess mainly the theoretical knowledge of Otorhinolaryngological diseases. The second part, a viva voce examination, is designed to test the clinical application of knowledge based on case scenarios and clinical conditions presented to the candidates. The inaugural examination written component took place in Mannheim/Germany in 2009 and the inaugural Viva Voce examination in Vienna/Austria in 2010. Up to and including the year 2013, 858 participants have attempted one of the two exam components. Of the 858 participants, 305 were successful in both examinations and obtained the accreditation of the European Diploma (European Board Certification). The historical origins, development of the examination, its formal arrangements and the format of the examination are presented in this article.

    There are currently many techniques and devices available for the diagnosis of lung cancer. However, rapid on-site diagnosis is essential for early-stage lung cancer, and in the current work we investigated a new diagnostic illumination nanotechnology. Tissue samples were obtained from lymph nodes, cancerous tissue, and abnormal intrapulmonary lesions at our interventional pulmonary suites. The following diagnostic techniques were used to obtain the samples: endobronchial ultrasound bronchoscopy; flexible bronchoscopy; and rigid bronchoscopy. Flexible and rigid forceps were used because several of the patients were intubated using a rigid bronchoscope. In total, 30 tissue specimens from 30 patients were prepared. CytoViva® illumination nanotechnology was subsequently applied to each of the biopsy tissue slides. A spectral library was created for adenocarcinoma, epidermal growth factor receptor mutation-positive adenocarcinoma, squamous cell carcinoma, usual interstitial pneumonitis, non-specific interstitial pneumonitis, typical carcinoid tumor, sarcoidosis, idiopathic pulmonary fibrosis, small cell neuroendocrine carcinoma, thymoma, epithelioid and sarcomatoid mesothelioma, cryptogenic organizing pneumonia, malt cell lymphoma, and Wegener's granulomatosis. The CytoViva software, once it had created a specific spectral library for each entity, was able to identify the same disease again in subsequent paired sets of slides of the same disease. Further evaluation of this technique could make this illumination nanotechnology an efficient rapid on-site diagnostic tool.

    This study explored the characteristics of violence against adolescents who received treatment at urgent and emergency care centers participating in the 2014 Violence and Accident Surveillance System (Sistema de Vigilância de Violências e Acidentes, VIVA) survey and determined the association between demographic variables and the characteristics of violent events. The sample was composed of 815 adolescents who responded to the 2014 VIVA survey. Correspondence analysis was used to determine possible associations between the variables. Victims were predominantly males and the most common form of aggression was the use of firearms and sharp objects. Among males aged between 15 and 19 years, violent acts were predominantly committed in public thoroughfares and by strangers, and the most common injuries consisted of fractures and cuts, while among younger adolescents aged between 10 and 14 years the most common form of aggression was threats made by friends at school. The most common place of occurrence among females was the home. It is concluded that violence against adolescents permeates the chief agencies of socialization - the family and school - demonstrating the need to mobilize the whole society in tackling this problem.

    Kuhn underlined the relevance of Galileo’s gestalt switch in the interpretation of a swinging body from constrained fall to time metre. But the new interpretation did not eliminate the older one. The constrained fall, both in the motion of pendulums and along inclined planes, led Galileo to the law of free fall. Experimenting with physical pendulums and assuming the impossibility of perpetual motion Huygens obtained a law of conservation of vis viva at specific positions, beautifully commented by Mach. Daniel Bernoulli generalised Huygens results introducing the concept of potential and the related independence of the ‘work’ done from the trajectories (paths) followed: vis viva conservation at specific positions is now linked with the potential. Feynman’s modern way of teaching the subject shows striking similarities with Bernoulli’s approach. A number of animations and simulations can help to visualise and teach some of the pendulum’s interpretations related to what we now see as instances of energy conservation.

    Airway management is a crucial skill essential to paramedics and personnel working in Emergency Medical Services and Emergency Departments: Lack of practice, a difficult airway, or a trauma situation may limit the ability of paramedics to perform direct laryngoscopy during cardiopulmonary resuscitation. Videoscope devices are alternatives for airway management in these situations. The ETView VivaSight SL (ETView; ETView Ltd., Misgav, Israel) is a new, single-lumen airway tube with an integrated high-resolution imaging camera. To assess if the ETView VivaSight SL can be a superior alternative to a standard endotracheal tube for intubation in an adult cadaver model, both during and without simulated CPR. ETView VivaSight SL tube was investigated via an interventional, randomized, crossover, cadaver study. A total of 52 paramedics participated in the intubation of human cadavers in three different scenarios: a normal airway at rest without concomitant chest compression (CC) (scenario A), a normal airway with uninterrupted CC (scenario B) and manual in-line stabilization (scenario C). Time and rate of success for intubation, the glottic view scale, and ease-of-use of ETView vs. sETT intubation were assessed for each emergency scenario. The median time to intubation using ETView vs. sETT was compared for each of the aforementioned scenarios. For scenario A, time to first ventilation was achieved fastest for ETView, 19.5 [IQR, 16.5-22] sec, when compared to that of sETT at 21.5 [IQR, 20-25] sec (p = .013). In scenario B, the time for intubation using ETView was 21 [IQR, 18.5-24.5] sec (p < .001) and sETT was 27 [IQR, 24.5-31.5] sec. Time to first ventilation for scenario C was 23.5 [IQR, 19-25.5] sec for the ETView and 42.5 [IQR, 35-49.5] sec for sETT. In normal airways and situations with continuous chest compressions, the success rate for intubation of cadavers and the time to ventilation were improved with the ETView. The time to glottis view, tube insertion

    Dye staining of applicators has been shown to be a reliable and objective method to test vaginal insertion in clinical microbicide trials, but different plastics, dyes, and product formulations may impact the accuracy of this method. Reportedly used applicators returned from 3 clinical trials were stained with 1% trypan blue. In a phase 1 study (VivaGel), using gel-filled HTI polypropylene applicators, 1271 (97%) of applicators stained positive. In a phase 1 and a phase 2a study (LACTIN-V) using linear low-density polyethylene applicators to deliver a dry powder formulation, 57 (95%) and 135 (86%) tested positive, respectively. Dye staining of vaginal applicators is an objective low-cost measure suitable for low-resource settings.

    Chronic psychological stress may raise the risk of preterm delivery by raising levels of placental corticotropin-releasing hormone (CRH). Women who have been the targets of racism or personal violence may be at particularly high risk of preterm delivery. The aims of this study are to examine the extent to which: (1) maternal experiences of racism or violence in childhood, adulthood, or pregnancy are associated with the risk of preterm birth; (2) CRH levels are prospectively associated with risk of preterm birth; and (3) CRH levels are associated with past and current maternal experiences of racism or violence. We have begun to examine these questions among women enrolled in Project Viva, a Boston-based longitudinal study of 6000 pregnant women and their children.

    2010-01-01

    A fatal Encephalomyocarditis virus (EMCV) infection epidemic involving fifteen primates occurred between October 2006 and February 2007 at the Natura Viva Zoo. This large open-field zoo park located near Lake Garda in Northern Italy hosts one thousand animals belonging to one hundred and fifty different species, including various lemur species. This lemur collection is the most relevant and rich in Italy. A second outbreak between September and November 2008 involved three lemurs. In all cases, the clinical signs were sudden deaths generally without any evident symptoms or only with mild unspecific clinical signs. Gross pathologic changes were characterized by myocarditis (diffuse or focal pallor of the myocardium), pulmonary congestion, emphysema, oedema and thoracic fluid. The EMCV was isolated and recognized as the causative agent of both outbreaks. The first outbreak in particular was associated with a rodent plague, confirming that rats are an important risk factor for the occurrence of the EMCV infection. PMID:20298561

    The reflectance confocal microscope has made translational progress in dermatology. 0.5 micrometer lateral resolution, 0.75mm field-of-view and excellent temporal resolution at ~15 frames/second serve the VivaScope well in the clinic, but it may be overlooked in basic research. This work reviews high spatiotemporal confocal microscopy and presents images acquired of various samples: zebra fish embryo where melanocytes with excellent contrast overly the spinal column, chicken embryo, where myocardium is seen moving at 15 frames/ second, calcium spikes in dendrites (fluorescence mode) just beyond the temporal resolution, and human skin where blood cells race through the artereovenous microvasculature.

    Cu2ZnSnS4 (CZTS) thin films were deposited viva spray pyrolysis technique at different substrate temperature. The effect of substrate temperature on the structural, morphological, compositional and optical properties was reported. The X-ray diffraction and Raman analysis revealed that prepared CZTS thin film show kesterite phase without any secondary phases. Moreover, these analyses indicated the internal compressive stress relaxed with substrate temperature for all CZTS thin films. The homogeneous nature of CZTS thin films were observed from surface morphology and chemical composition study. The optical study provided good optical absorption (104 cm-1) in the visible region and band gap energy was decreased and found quite close to the optimum value of about 1.57 eV-1.49 eV for solar cell application.

    Lung cancer therapies during the last decade have focused on targeting the genome of cancer cells, and novel routes for administering lung cancer therapies have been investigated for decades. Aerosol therapies for several systematic diseases and systemic infections were introduced into the market a decade ago. One of the main issues of aerosol therapies has been the ability to investigate the deposition of a drug compound throughout the systematic circulation and lymph node circulation. Until now, none of the published studies have efficiently shown the deposition of a chemotherapy pharmaceutical within the lymph node tissue. In our current work we present, for the first time, with the novel CytoViva(®) (AL, USA) technique, the deposition of cisplatin aerosol therapy in surgically resected stage II lymph nodes from lung cancer patients. Finally, we present the distribution of cisplatin in correlation with the cisplatin concentration in different lymph stations and comment on the possible mechanisms of distribution.

    This study aimed to identify factors associated with treatment of victims of domestic and family violence in emergency rooms in Brazil. This is a case-control study based on the Surveillance System for Violence and Accidents (VIVA), 2011. Women ≥ 18 years who were victims of family and domestic violence were selected as cases and compared to accident victims (controls). Adjusted odds ratios were estimated by unconditional logistic regression. 623 cases and 10,120 controls were included. Risk factors according to the adjusted analysis were younger age (18-29 years), low schooling, lack of paid work, alcohol consumption, having sought treatment in a different health service, and violence on weekends or at night or in the early morning hours. The study concludes that domestic and family violence shows alcohol consumption as a strongly associated factor. Days and hours with the highest ocurrence reveal the need to adjust emergency services to treat victims.

    Reflectance-mode confocal microscopy (RCM) is a new in vivo skin imaging technique. We present our one-year experience in RCM examinations in skin tumors and the retrospective analysis of patients enrolled in the Dermatological Department of 'N. Paulescu' Institute using the Fotofinder Dermoscope IIŴ for the dermatoscopy analysis and VivaScope 1500Ŵ for in vivo RCM. We established the rank of RCM in the complex algorithm of skin cancer diagnose, showing that the presented experience can open new possibilities to implement this automated image analyzing system in the routine practice. Our analyzed cases clearly showed that confocal microscopy, therefore, optical biopsy, could guide the clinician towards an accurate diagnosis before surgical removal. Moreover, we emphasized that the development of this technique increases the potential of future teledermatologic applications.

  7. Assessment of mental health nursing competence using level III academic marking criteria: the Eastbourne assessment of practice scale.

    1999-02-01

    The assessment of clinical competence in nursing represents a challenge to the profession. There is a need for assessment of practice skills through evaluative observation of performance but unfortunately such methods are not regularly used as a basis for assessment within most academic nursing institutions. Instead there is still a reliance upon more traditional types of academic assessment usually done through a written medium. Such methods whilst academically rigorous do not easily assess actual real life competence. This paper will describe how this tension was addressed through the development of a tool that combines observation of real life practice and viva style questioning with an assessment marking grid whose descriptors represent level III practice. Its inter rater reliability (rs = 0.88, P < 0.01) was established by 14 clinical nurse specialists in cognitive behaviour therapy who assessed a single video taped recording of a post-registration students performance whilst undergoing training in cognitive behaviour therapy.

    Life-threatening ear, nose, and throat (ENT) emergencies are uncommon but require immediate skilled management. We investigated if traditional lecture-based teaching can be improved by a simulation and lecture hybrid approach. A single-blinded, prospective, randomized controlled trial. Two groups of interns with no previous ENT experience were randomized to one of two training groups: a simulation/lecture hybrid group or a lecture-only control group. Both groups received 90 minutes of training covering the assessment of critically ill patients and four ENT emergency topics. Both groups received the same initial lecture slides. The control group received additional slides, and the simulation group received simulated emergency scenario training using basic mannequins. Following the training, candidates were asked to provide feedback on their perception of training, and they were formally assessed with a standardized one-to-one viva. Thirty-eight interns were recruited: 18 in the control group and 20 in the simulation group. The candidates in the simulation group performed significantly better in all viva situations (P < .05) and had better perception of learning (P < .05). Additionally, the simulation group was more likely to recommend the training to a colleague (P < .05). We have demonstrated that replacing traditional lecture-based training with a mixture of lectures and emergency scenario simulation is more effective at preparing junior doctors for ENT emergencies, and better met their learning needs. Implementing this kind of teaching is feasible with a minimum of additional resources or time. 1b © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

    Study Objectives: Poor sleep in childhood is associated with increased obesity risk, possibly by affecting appetite-regulating hormones such as leptin. We examined short- and long-term sleep duration and quality in relation to leptin in two US pediatric cohorts. Design: Analysis of data from two prospective cohort studies. Setting: Population-based. Adolescent polysomnography assessments performed in a clinical research unit. Patients or Participants: Children in Project Viva (n = 655) and adolescents in the Cleveland Children's Sleep & Health Study (n = 502). Interventions: N/A. Measurements and Results: In Project Viva, mothers reported average child sleep duration annually from infancy through age 7, and we measured leptin at ages 3 and 7. In the Cleveland Children's Sleep & Health Study, we collected self-reported sleep duration, polysomnography-derived measures of sleep quality, and fasting leptin at ages 16-19. In sex-stratified linear regression analyses adjusted for sociodemographic characteristics and adiposity, chronic curtailed sleep was associated with lower leptin at age 7 in girls; a one-unit decrease in sleep score was associated with a 0.08 decrease in log leptin (95%CI: 0.01,0.15). The association was stronger in girls with greater adiposity (P = 0.01). Among adolescents, shorter sleep was associated with lower leptin in males; each one-hour decrease in sleep duration was associated with a 0.06 decrease in log leptin (95%CI: 0.00, 0.11). Sleep duration was not associated with leptin at other ages. Sleep quality indices were not associated with leptin. Conclusions: Our results suggest possible age-specific sexual dimorphism in the influence of sleep on leptin, which may partly explain inconsistencies in the literature.

    Although ultrasound is a core skill for many clinical specialties, UK medical schools are not currently required to teach this skill. The College of Emergency Medicine (CEM) has championed the use of ultrasound to answer focused clinical questions in emergency settings. We have designed and piloted an ultrasound training course for undergraduate medical students addressing one important indication: ultrasound assessment of the abdominal aorta. Fourteen clinical students, who had no prior experience of using ultrasound, received focused ultrasound training in the form of didactic instruction, a short bedside practical workshop and self-directed learning over a 20-day period. At the end of this period, the students were assessed by a structured viva and an observed structured clinical examination (OSCE) used for accreditation by the CEM. The primary endpoint was the number of students who passed the assessment. The secondary endpoint was the accuracy of the students' anatomical measurements. Thirteen of the 14 (93%) students completed the training and assessment. Eight of the 13 (62%) students passed both the viva and OSCE, and were deemed to have achieved the CEM standard. The measurements by the competent students were not statistically different from those of experienced practitioners. We have shown for the first time that it is feasible to train inexperienced undergraduate students to scan the abdominal aorta to a professional standard using a focused training course. It is time for the medical education community to address whether focused ultrasound training should accompany traditional clinical skills, such as using a stethoscope, in UK medical school curricula. © Blackwell Publishing Ltd 2011.

    Rapid Prototyping (RP) is a technique used in industry for manufacturing prototypes. Its capability to physically reproduce geometrical complex shapes is getting increasing interest in many fields of medicine. In the field of vascular surgery, replicas of artery lumen have utility in complex cases or when standard imaging is felt to be equivocal. Replicas can also facilitate experimental studies of computational vascular fluid-dynamics permitting in-vitro reproductions of blood flow in living subjects before and after surgery. The VIrtual VAscular (VIVA) project at CRS4, developed a system able to process three-dimensional (3D) datasets extracted from a Computer Tomography (CT) apparatus, visualize them, reconstruct the geometry of arteries of specific patients, and simulate blood flow in them. In this paper, the applicability of RP techniques to VIVA's real size replicas of an autoptic carotid vessel lumen is presented and an overview of the RP based system developed is provided. The techniques used in our prototype are discussed and experimental results for the creation of a human carotid lumen replica are analyzed. We discuss in detail the pipeline of manufacturing process: 3D geometric reconstruction from segmented points, geometry tessellation, STL (Stereo Lithography format) conversion. Moreover we illustrate some technical details of the specific RP technique used to build the lumen replicas, which is called Fused Deposition Modelling (FDM), the materials used for prototypes, throughput time and costs of the FDM models realized. The system is totally based on open-source software. This enables us to control each step of the pipeline, from data acquisition to STL export file. In this context, we present main sources of error encountered during all manufacturing process stages.

  12. Real-Time Demonstration of Split Skin Graft Inosculation and Integra Dermal Matrix Neovascularization Using Confocal Laser Scanning Microscopy

    2009-01-01

    Objectives: During the first 48 hours after placement, an autograft “drinks” nutrients and dissolved oxygen from fluid exuding from the underlying recipient bed (“plasmatic imbibition”). The theory of inosculation (that skin grafts subsequently obtain nourishment via blood vessel “anastomosis” between new vessels invading from the wound bed and existing graft vessels) was hotly debated from the late 19th to mid-20th century. This study aimed to noninvasively observe blood flow in split skin grafts and Integra™ dermal regeneration matrix to provide further proof of inosculation and to contrast the structure of vascularization in both materials, reflecting mechanism. Methods: Observations were made both clinically and using confocal microscopy on normal skin, split skin graft, and Integra™. The VivaScope™ allows noninvasive, real-time, in vivo images of tissue to be obtained. Results: Observations of blood flow and tissue architecture in autologous skin graft and Integra™ suggest that 2 very different processes are occurring in the establishment of circulation in each case. Inosculation provides rapid circulatory return to skin grafts whereas slower neovascularization creates an unusual initial Integra™ circulation. Conclusions: The advent of confocal laser microscopy like the VivaScope 1500™, together with “virtual” journals such as ePlasty, enables us to provide exciting images and distribute them widely to a “reading” audience. The development of the early Integra™ vasculature by neovascularization results in a large-vessel, high-volume, rapid flow circulation contrasting markedly from the inosculatory process in skin grafts and the capillary circulation in normal skin and merits further (planned) investigation.

    The results of rabies in vivo and postmortem laboratory detection in two cases registered in the Republic of Tatarstan are reported: a victim bitten by a wolf in 2002 and another one bitten by a stray dog on Goa Island, India, in 2013. In the patient bitten by a wolf cornea imprints studies using the method of fluorescent antibodies (MFA) showed rabies-positive result 6 days before the patient's death. The results were confirmed by postmortem examination of different parts of the brain and salivary glands using the MFA, enzyme-linked immunosorbent assay (ELISA), optical microscopy, and bioassay methods. In the patient bitten by a stray dog the rabies virus specific antigen was detected by eye cornea studies using the MFA method and saliva studies using the ELISA. The rabies virus genome was also isolated from saliva and tear fluid using nested reverse-transcription polymerase chain reaction (RT-PCR) 9 days before the patient's death. The in viva studies results were consistent with the postmortem study of different parts of the brain using the MFA, enzyme-linked immunosorbent assay (ELISA), optical microscopy, and bioassay methods. All the infection-positive results of both in viva and postmortem studies were consistent with the clinical studies, i.e. rabies diagnosis was confirmed. The analysis of the rabies virus gene G fragment nucleotide sequence of 238 nd length showed a slight difference between the studied isolates (2 rabies) and the RABV AY9563I9 (1.68%), difference by 10.5% from the Vnukovo-32 vaccine strains and by 10.9% from the SAD B19 rabies strain, respectively (rabies viruses of 1st genotype). It was also significantly different from the lissaviruses of 2,4,5, and 6 genotypes (21 .0-32.7%). The obtained results indicate phylogenetic closeness of the studied isolates (2 rabies) with the RABV AY956319 rabies virus strain belonging to the 1st genotype.

    Objectives: The aim of this in-vitro experimental study was to assess the effect of application of a desensitizing varnish on the enamel and dentin marginal seal. Materials and Methods: Seventy-two freshly extracted, intact human premolar teeth were divided into four groups (n=18). Class V cavities (3mm in length, 2mm in width and 2mm in depth) were prepared on the buccal surface of each tooth. The following sealing materials were applied in the four groups: One-step Clearfil S3 Bond (S3) self-etch adhesive, two-step Clearfil SE Bond (SE) self-etch adhesive, S3 Bond+ VivaSens desensitizing varnish (VS+S3) and Clearfil SE Bond + VivaSens (VS+SE). The cavities on the teeth were then incrementally filled with Z350 light-cure composite. The teeth were stored in distilled water for 24 hours at 37°C, and were then thermocycled for 1000 cycles. Then, all the specimens were prepared for dye penetration test and were immersed in 2% basic fuchsin dye and incubated at 37°C for 24 hours. The teeth were then sectioned buccolingually along the center of restorations with a diamond disk. Microleakage at the tooth-restoration interface was assessed in the enamel and dentin margins blindly using dye penetration under a stereomicroscope at ×20 magnification. Results: There was significantly greater leakage at the enamel and dentin margins in group VS+SE than in group SE; also, these values were higher in group VS+S3 than in S3. Conclusion: Combined application of desensitizing varnish and self-etch adhesives seems to increase microleakage in composite restorations. Thus, its application is not suggested. PMID:27507991

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

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

    Tracheostomy is a procedure that can be performed in any age group, including children under 1year of age. Unfortunately health professionals in Brazil have great difficulty dealing with this condition due to the lack of standard care orientation. This clinical consensus by Academia Brasileira de Otorrinolaringologia Pediátrica (ABOPe) and Sociedade Brasileira de Pediatria (SBP) aims to generate national recommendations on the care concerning tracheostomized children. A group of experts experienced in pediatric tracheostomy (otorhinolaryngologists, intensive care pediatricians, endoscopists, and pediatric pulmonologists) were selected, taking into account the different regions of Brazil and following inclusion and exclusion criteria. The results generated from this document were based on the agreement of the majority of participants regarding the indications, type of cannula, surgical techniques, care, and general guidelines and decannulation. These guidelines can be used as directives for a wide range of health professionals across the country that deal with tracheostomized children.

  11. On the mechanism of nanoparticulate CeO2 toxicity to freshwater algae.

    PubMed

    Angel, Brad M; Vallotton, Pascal; Apte, Simon C

    2015-11-01

    The factors affecting the chronic (72-h) toxicity of three nanoparticulate (10-34nm) and one micron-sized form of CeO2 to the green alga, Pseudokirchneriella subcapitata were investigated. To characterise transformations in solution, hydrodynamic diameters (HDD) were measured by dynamic light scatter, zeta potential values by electrophoretic mobility, and dissolution by equilibrium dialysis. The protective effects of humic and fulvic dissolved organic carbon (DOC) on toxicity were also assessed. To investigate the mechanisms of algal toxicity, the CytoViva hyperspectral imaging system was used to visualise algal-CeO2 interactions in the presence and absence of DOC, and the role of reactive oxygen species (ROS) was investigated by 'switching off' ROS production using UV-filtered lighting conditions. The nanoparticulate CeO2 immediately aggregated in solution to HDDs measured in the range 113-193nm, whereas the HDD and zeta potential values were significantly lower in the presence of DOC. Negligible CeO2 dissolution over the time course of the bioassay ruled out potential toxicity from dissolved cerium. The nanoparticulate CeO2 concentration that caused 50% inhibition of algal growth rate (IC50) was in the range 7.6-28mg/L compared with 59mg/L for micron-sized ceria, indicating that smaller particles were more toxic. The presence of DOC mitigated toxicity, with IC50s increasing to greater than 100mg/L. Significant ROS were generated in the nanoparticulate CeO2 bioassays under normal light conditions. However, 'switching off' ROS under UV-filtered light conditions resulted in a similar IC50, indicating that ROS generation was not the toxic mechanism. The CytoViva imaging showed negligible sorption of nanoparticulate CeO2 to algal cells in the presence of DOC, and strong sorption in its absence, suggesting that this was the toxic mechanism. The results suggest that DOC in natural waters will coat CeO2 particles and mitigate toxicity to algal cells.

    Observational and experimental evidence demonstrates that protein intake in infancy programs linear growth. To our knowledge, few studies have examined prenatal maternal protein intake. Our objective was to examine associations of maternal protein intake during pregnancy with offspring linear growth. We analyzed data from 1961 mother-child pairs in Project Viva. We assessed first- and second-trimester diet with the use of food-frequency questionnaires and analyzed protein intake as grams per kilogram prepregnancy weight per day. We used research measures of offspring length at birth and in infancy (∼6 mo), early childhood (∼3 y), and midchildhood (∼7 y), as well as clinical growth measures obtained from after birth through midchildhood. We calculated sex-specific birth length z scores for gestational age with the use of international reference data. We used mixed models with repeated length measures to predict individual length gain velocities for birth to <6 mo and 6 mo to 7 y of age, then used these velocities as outcomes in adjusted linear regression models with maternal protein intake as the main predictor. Mean (range) second-trimester protein intake was 1.4 g · kg(-1) · d(-1) (0.3-3.1 g · kg(-1) · d(-1)). After adjusting for maternal sociodemographics, gestational weight gain, maternal and paternal height, and (for postdelivery outcomes) child sex, gestational age, and breastfeeding duration, each 1-SD (0.36 g · kg(-1) · d(-1)) increment in second-trimester protein intake corresponded to a -0.10 (95% CI: -0.18, -0.03) change in birth length z score, a -0.03 cm/mo (95% CI: -0.05, -0.01 cm/mo) change in slope of length growth from birth to <6mo, and a -0.09 cm/y (95% CI: -0.14, -0.05 cm/y) change in slope of length growth from 6 mo to midchildhood. Results were similar for first-trimester intake. In a population with relatively high protein intake during pregnancy, higher protein intake was associated with shorter offspring birth length and slower

    The aim of this study was to evaluate particle enhanced turbidimetric inhibition immunoassay (PETINIA) recently developed for mycophenolic acid (MPA) determination in plasma and to compare it with a reference high-performance liquid chromatography (HPLC) method, using samples from heart transplant recipients. The results are presented in the context of PETINIA being compared with enzyme multiplied immunoassay technique (EMIT). PETINIA evaluation was performed using 194 routine trough plasma samples at steady state. EMIT was evaluated using 677 samples from 61 steady-state 12-hour profiles obtained from 35 heart transplant patients. Evaluation was undertaken on a Dimension EXL 200 analyzer (PETINIA) and on a Viva-E analyzer (EMIT). The mean MPA concentration measured by PETINIA was significantly higher than that measured by high-performance liquid chromatography combined with UV detector (2.36 ± 1.30 mcg/mL versus 1.82 ± 1.23 mcg/mL, respectively, P < 0.0001). Bland-Altman analysis revealed a mean bias of 0.54 mcg/mL [95% confidence interval (CI), 0.49-0.59] comprising 33.48% (95% CI, 30.34-36.61). Passing-Bablok regression was: y = 1.100x + 0.38 (95% CI for slope: 1.044-1.154 and for intercept: 0.30-0.47). Regardless of a significant observed correlation (r = 0.9230, P < 0.0001), the statistical analyses showed a significant difference between PETINIA and the reference chromatographic method. The mean MPA concentration measured by EMIT was significantly higher than that measured by HPLC (7.48 ± 8.34 mcg/mL versus 5.57 ± 6.61 mcg/mL, respectively, P < 0.0001) with a mean bias of 1.91 mcg/mL (95% CI, 1.75-2.07) comprising 35.91% (95% CI, 34.37-37.45). The significant difference between EMIT and HPLC was confirmed by Passing-Bablok regression: y = 1.300x + 0.24 (95% CI for slope: 1.279-1.324 and for intercept: 0.18-0.29). The analysis of the determinations, grouped by sampling time, revealed positive bias between EMIT and HPLC ranging from 24.54% to 42.77% and

    Brazil has vocation for food production, both vegetable and animal, with the sheep industry having an expanding activity. However, productivity rates are often bellowing the possibilities of the country. Here, the roles the native breeds may develop in this expanding activity are described. Breeds considered are the hair breeds Santa Inês, Morada Nova, Somális Brasileira, Cariri, and Rabo Largo, and the wool breeds Bergamácia Brasileira, Crioula Lanada, and Pantaneira. These breeds have arisen in environments that may be considered difficult for other (exotic) breeds, less adapted to the local conditions. The hair breeds emerged in a semi-arid environment, a hot and with low rainfall region, of the Northeast of Brazil. The Crioula Lanada is the only breed that originated in the South, in a subtropical region with cold winters. The genetic group Pantaneira had its origin in an environment with higher humidity, especially soil moisture. The Bergamácia Brasileira derived from the Italian Bergamasca breed, which was first introduced in northeastern Brazil. Animals from these breeds have been regarded as robust, with lower requirements for maintenance, resistant to worms, and easy to handle. On the other side, as they are generally smaller than the exotic breeds used for meat production, they are often considered as less productive. In this literature review, a possibility of valorizing them, both as purebred or in crossbreeding programs, especially for meat production is addressed. These breeds are part of the genetic, historical, and cultural heritage of Brazil, and if used properly, according to the different environments and production systems, they can also be very important in the development of the sheep industry.

    Positively surface-charged poly(lactide-co-glycolide) (PLGA)/Eudragit RL nanoparticles (NPs) were designed to increase retention time and sustain release profile in joints after intra-articular injection, by forming micrometer-sized electrostatic aggregates with hyaluronic acid, an endogenous anionic polysaccharide found in high amounts in synovial fluid. The cationic NPs consisting of PLGA, Eudragit RL, and polyvinyl alcohol were fabricated by solvent evaporation technique. The NPs were 170.1 nm in size, with a zeta potential of 21.3 mV in phosphate-buffered saline. Hyperspectral imaging (CytoViva®) revealed the formation of the micrometer-sized filamentous aggregates upon admixing, due to electrostatic interaction between NPs and the polysaccharides. NPs loaded with a fluorescent probe (1,1′-dioctadecyl-3,3,3′,3′ tetramethylindotricarbocyanine iodide, DiR) displayed a significantly improved retention time in the knee joint, with over 50% preservation of the fluorescent signal 28 days after injection. When DiR solution was injected intra-articularly, the fluorescence levels rapidly decreased to 30% of the initial concentration within 3 days in mice. From these findings, we suggest that PLGA-based cationic NPs could be a promising tool for prolonged delivery of therapeutic agents in joints selectively. PMID:26345227

    The injected transfer orbit of lunar probe Chang'E 5T1 (CE-5T1) is determined immediately after the probe separates from its launcher. As the first orbit in the lunar flight, the CE-5T1 injected transfer orbit is crucial to the consequence of rocket vehicle launch mission and the probe's subsequent midway orbital manoeuvre. In this paper, we discuss the problem of using rocket GPS measurements to determine the probe velocity increment due to mechanical separation, and subsequently the injected transfer orbit determination of CE-5T1. Motivated by the post-mission analysis of lunar probe Chang'E 3 (CE-3), we give theoretical evidence to explain the physical phenomenon of semi-major axis sudden change at the probe separation instant through the derivation of the Vis-Viva equation. In succession, we focus on the description of the procedure used for the orbit determination performed on separated arcs of rocket GPS measurements through the use of momentum conservation to determine the probe separation velocity. Finally, actual flight data of the CE-3 and CE-5T1 missions are used for the validation.

  17. Effect of examination stress on mood, performance and cortisol levels in medical students.

    Stress produces definable mental and physiological reactions in the body. Mild stress is beneficial in cognitive tasks and performance but persistently high stress may lead to neuropsychiatric illnesses like anxiety and depression. Examinations act as stressor and activate hypothalamic-pituitary adrenal axis causing an increase in cortisol level, which is reflected in saliva. Present study was done on 35 medical students. Their mood parameters were assessed, using Depression Anxiety Stress Scale (DASS) scoring, and salivary cortisol levels using quantitative ELISA. Subjects were evaluated for mood parameters two times, one during relaxed state (with no examinations in preceding 2 weeks and in coming 2 weeks) and another during stressed state (on the day of viva voce examination). The levels of mood parameters and salivary cortisol were significantly raised during examination stress. The changes in stress level significantly correlated with change in levels of anxiety and salivary cortisol though there was no significant effect on the performance. Males and females showed similar changes in mood parameters. This study suggests that as examinations act as unavoidable stressors, the medical educators as well as students should be made aware of the negative consequences of stress faced during medical training. Efficient relaxation program as well as counseling services should be provided to stressed students so that they are able to cope better with examination stress.

    Differential exposure to minority status stressors may help explain differences in United States (US)-born and foreign-born Black women's birth outcomes. We explored self-reports of racism recorded in a survey of 185 US-born and 114 foreign-born Black pregnant women enrolled in Project Viva, a prospective cohort study of pregnant women in Boston, Massachusetts, USA. Self-reported prevalence of personal racism and group racism was significantly higher among US-born than foreign-born Black pregnant women, with US-born women having 4.1 and 7.8 times the odds, respectively, of childhood exposure. In multivariate analyses, US-born women's personal and group racism exposure also was more pervasive across the eight life domains we queried. Examined by immigrant subgroups, US-born women were more similar in their self-reports of racism to foreign-born women who moved to the US before age 18 than to women who immigrated after age 18. Moreover, US-born women more closely resembled foreign-born women from the Caribbean than those from Africa. Differential exposure to self-reported racism over the life course may be a critically important factor that distinguishes US-born Black women from their foreign-born counterparts.

    This article records the traditional knowledge of crab gatherers in the city of Conde, in the North Coast Region of Bahia State, Northeastern Brazil. Data on biological and ecological aspects of economically important brachyuran crustaceans have been obtained from semi-structured interviews and in loco observations conducted from September 2007 to December 2009. A total of 57 fishermen of both genders, aged between 10 and 78 years have been interviewed (individually or collectively) in different contexts; interviewees were asked about aspects such as external morphology, life cycle, trophic ecology, and spatial and temporal distribution of the major economically important brachyuran crustaceans in the region. Seven fishing communities were visited: Siribinha, Sítio do Conde, Poças, Ilha das Ostras, Cobó, Buri and Sempre Viva. Data were analyzed by comparing the information provided by participants with those from the specialized academic literature. The results show that artisanal fishermen have a wide ranging and well-grounded knowledge on the ecological and biological aspects of crustaceans. Crab gatherers of Conde know about growth and reproductive behavior of the animals they interact with, especially with regard to the three major biological aspects: "molt", "walking dance" and "spawning". This knowledge constitutes an important source of information that should be considered in studies of management and sustainable use of fishery resources in the North Coast Region of Bahia State.

    The scope of this study was to analyze the trend of completeness of the data on violence perpetrated against adolescents registered in the State of Pernambuco between 2009 and 2012. This involved a cross-sectional survey of 5,259 adolescents, who were the victims of violence reported in SINAN-VIVA of the Pernambuco State Health Department. Simple linear regression was used to investigate the trend of completeness of the variables. The percentages of completeness were considered to be dependent variables (Y) and the number of years as independent variables (X). The results show a significant increase of 204% in the number of notifications. However, of the 34 variables analyzed, 27 (79.4%) showed a stationary trend, 6 (17.6%) a downward trend, and only one variable (2.9%) an upward trend. Completeness was considered 'Very Poor' for the variables: Education (47.3%), Full Address (21.3%), Occurrence Time (38%) and Use of Alcohol by the Attacker (47%). Therefore, despite the large increase in the number of notifications, data quality continued to be compromised, hampering a more realistic analysis of this group.

    The scope of this article is to outline the scenario of domestic, sexual and other forms of violence against children (0-9 years old) in Brazil for the year 2010. It is based on data from reports of domestic, sexual and other forms of violence registered with SINAN - Information System for Notifiable Diseases (Continuous VIVA). Absolute and relative numbers are presented, derived from reported violence, discriminating between children under 1 year of age and those between 1-9 years old, due to the specificities that exist in these age groups. Throughout the country, the number of reports among those under 10 years of age is low (17.1%). Differences were found for the distribution of reports in the different Brazilian States. Few municipalities and few services reported violence to SINAN-Net in 2010 in the country. Some differences were found between children under 1 year of age and those between 1 and 9 years of age, as for instance the relationship between the profile of the violence, the victim and the perpetrator, and the handling of the case. The quality of the reported information is discussed showing the high level of unreported data in some spaces of the reporting form. Lack of information may prejudice comprehension of the phenomenon, interfering with the planning, organization and operation actions of the health services in the country.

    Confocal laser scanning microscopy (CLSM) allows noninvasive visualization of human skin in vivo, without needing to fix or section the tissue. Melanocytes and pigmented keratinocytes at the level of the basal layer form bright dermal papillary rings which are readily amenable to identify in confocal images. Our purpose was to explore the role of dermal papillary rings in assessment of lesion location, the diagnosis, differential diagnosis of lesions and assessment of therapeutic efficacy by in vivo CLSM. Seventy-one patients were imaged with the VivaScope 1500 reflectance confocal microscope provided by Lucid, Inc. The results indicate that dermal papillary rings can assess the location of lesion; the application of dermal papillary rings can provide diagnostic support and differential diagnosis for vitiligo, nevus depigmentosus, tinea versicolor, halo nevus, common nevi, and assess the therapeutic efficacy of NBUVB phototherapy plus topical 0.1 percent tacrolimus ointment for vitiligo. In conclusion, our findings indicate that the dermal papillary rings play an important role in the assessment the location of lesion, diagnosis, differential diagnosis of lesions and assessment of therapeutic efficacy by in vivo CLSM. CLSM may be a promising tool for noninvasive examination in dermatology. However, larger studies are needed to expand the application of dermal papillary rings in dermatology.

    This study aimed to analyze the profile of treatment for accidents and violence involving children under 10 years of age in Brazil in the year 2011. This was a cross-sectional descriptive study in 71 emergency services in the Brazilian Unified National Health System (SUS), located in the national capital and 24 state capitals. Data were obtained from the Ministry of Health's system of sentinel surveillance services for Violence and Accidents (VIVA Survey). The highest proportion of injuries (67.4%) occurred inside the child's home. Among unintentional injuries, falls were the most frequent (52.4%), followed by running into objects or persons (21.8%) and traffic injuries (10.9%), especially as passengers (bicycles were an important means of transportation involved in the injuries). The vast majority of unintentional injuries are avoidable, and educational measures should be adopted, especially with parents, teachers, the community, and health workers, calling attention to the risks and the adoption of safe behaviors in the home, at school, and in leisure-time activities. Cases of violence are subject to mandatory reporting, and prompt measures should be taken to protect victims.

    Multisensory integration of spatial information occurs late in childhood, at around eight years (Gori, Del Viva, Sandini, & Burr, 2008). For younger children, the haptic system dominates size discrimination and vision dominates orientation discrimination: the dominance may reflect sensory calibration, and could have direct consequences on children born with specific sensory disabilities. Here we measure thresholds for visual discrimination of orientation and size in children with movement disorders of upper limbs. Visual orientation discrimination was very similar to the age-matched typical children, but visual size discrimination thresholds were far worse, in all eight individuals with early-onset movement disorder. This surprising and counterintuitive result is readily explained by the cross-sensory calibration hypothesis: when the haptic sense is unavailable for manipulation, it cannot be readily used to estimate size, and hence to calibrate the visual experience of size: visual discrimination is subsequently impaired. This complements a previous study showing that non-sighted children have reduced acuity for haptic orientation, but not haptic size, discriminations (Gori, Sandini, Martinoli, & Burr, 2010). Together these studies show that when either vision or haptic manipulation is impaired, the impairment also impacts on complementary sensory systems that are calibrated by that one.

    Several immunoassay methods for screening of abused drugs in whole blood were evaluated in post-mortem forensic toxicology. Blood samples known to be positive or negative for opiates, cannabinoids or amphetamines by gas chromatography-mass spectrometry (GC-MS) were analysed by EMIT II Plus and EMIT d.a.u., Syva RapidTest and Triage 8 after acetone precipitation. In these experiments, the EMIT immunoassay method was modified by using the Dade Behring VIVA analyser to detect substances more sensitively. Low concentrations of abused drugs were detected in blood samples. The sensitivities of the modified EMIT method for opiates, cannabinoids and amphetamines were 100, 86 and 98%, respectively, whereas the values were below 86% with the other methods. The specificities of all immunoassay methods for opiates and cannabinoids were 83% or above but 51-85% for amphetamines. Sample rejection occurred in a few cases with the EMIT amphetamine assays. The modified EMIT immunoassay system presented here seems to be useful for screening of drugs of abuse in post-mortem blood samples, especially when urine is not available.

    This paper aimed to describe the epidemiological profile of pedestrians injured in traffic accidents treated at urgent and emergency facilities participating in the 2014VIVA Survey and the characterization of these events and consequences for these victims. This is a cross-sectional study conducted in the period from September to November 2014 in 24 Brazilian state capitals and the Federal District. We analyzed variables that characterize the victim, the accident and its severity and case outcome. We calculated simple and relative frequencies and performed a bivariate analysis by gender and age group. We used the Rao-Scott test with a 5% significance level in order to verify the independence of variables. Results show that 34.3% of attendances were for individuals aged 20-39 years, 54.2% had brown skin and 35.9% of individuals had up to 4 years of schooling. Run-overs occurred mainly at night (33.6%) and in the afternoon (31.3%). Most cases resulted in discharge in all age groups, but 41.6% of the elderly (60 years and over) required hospitalization. We stress the need for public investment, prioritizing pedestrian circulation in traffic and road infrastructure planning.

    We report, in this paper, several findings about the swimming and attachment mechanisms of Giardia lamblia trophozoites. These data were collected using a combination of a high-contrast CytoViva imaging system and a particle image velocimetry camera, which can capture images at speeds greater than 800 frames/s. Using this system, we discovered that, during rapid swimming of Giardia trophozoites, undulations of the caudal region contributed to forward propulsion combined with the beating of the flagella pairs. It was also discovered, in contrast to previous studies with 10 times slower image sampling technique, that the anterior and posterolateral flagella beat with a clearly defined power stroke and not symmetrical undulations. During the transition from free swimming to attachment, trophozoites modified their swimming behavior from a rapid rotating motion to a more stable planar swimming. While using this planar swimming motion, the trophozoites used the flagella for propulsion and directional control. In addition to examination of the posterolateral and anterior flagella, a model to describe the motion of the ventral flagella was derived, indicating that the ventral flagella beat in an expanding sine wave. In addition, the structure of the ventrocaudal groove creates boundary conditions that determine the form of beating of the ventral flagella. The results from this study indicate that Giardia is able to simultaneously generate both ciliary beating and typical eukaryotic flagellar beating using different pairs of flagella.

  10. Impact of infant feeding practices on childhood obesity.

    Childhood obesity is a complex disease influenced by genetic and environmental factors and their interactions. The current surge in childhood obesity in the United States is attributable to an interaction between a genetic predisposition toward obesity and a permissive environment. Several recent systematic reviews and meta-analyses have been published on the association between breast-feeding and childhood obesity. In these analyses, adjustment for confounding factors attenuated or nullified the protective effect of breast-feeding on later obesity. The Viva La Familia Study was designed to identify genetic and environmental factors affecting obesity and its comorbidities in 1030 Hispanic children from 319 families. Odds ratios for potential risk factors associated with childhood overweight were computed using binary logistic regression for panel data. Early infant-feeding practices were not significant. Salient independent risk factors for childhood obesity in this cohort of Hispanic children were age, birth weight, maternal obesity, paternal obesity, number of children in the family, and the percentage of awake time spent in sedentary activity. Breast-feeding may have a small protective effect against childhood obesity, although residual confounding may exist. Human milk is exquisitely fitted for optimal infant growth and development and may uniquely modulate neuroendocrine and immunologic pathways involved in the regulation of body weight. Nevertheless, other genetic and environmental determinants such as socioeconomic status, parental obesity, smoking, birth weight, and rapid infancy weight gain far supersede infant-feeding practices as risk factors for childhood obesity.

    Geosciences are more and more part of the primary school curriculum. However, the subjects of Earth and Astronomy remain very lightly approached. In Portugal, after the mandatory class period from 9 a.m. to 4 p.m., a complementary Experimental Sciences class of 1 or 2 hours per week has been introduced. In the past two years, through a partnership with the Lagos City Hall, the Lagos Ciência Viva Science Centre (CCVL) has been responsible for these classes in 8 primary schools engaging roughly 500 students in STEM activities that aim to support students to better understand and explore general scientific (and geosciences) subjects. But what is the impact of these classes in their knowledge and thinking procedure? What competencies and skills are gained, if any? And what is the background of our students regarding scientific literacy and habits? To answer these questions, we used questionnaires and personal meaning mapping to characterize our primary school population concerning scientific literacy and habits, assess the impact in their knowledge and identify potential caveats in our teaching and evaluation methods.

    Objectives To determine the safety of the candidate vaginal microbicide SPL7013 Gel (VivaGel®) when applied to the penis. Methods A randomized, double blind, placebo controlled study. Thirty-six healthy men (18 circumcised, 18 uncircumcised), were randomized in a 2:1 ratio and treated with 3% SPL7013 Gel (N=24) or placebo gel (N=12), applied once daily for 7 days. Genital toxicity was determined by interview, diary, and examination. Results There were 10 genital adverse events (AEs) in 6 men (25%) receiving SPL7013 Gel, and 5 genital AEs in 4 men (33%) receiving the placebo that were possibly or probably related to the study product (difference of −8%, 95% CI: −40% to 23%, p=0.70). The most common genital AEs were genital pruritus and application site erythema. All genital AEs were mild (grade 1), and all but one, in the placebo group, were transient. Analysis of vital signs, non-genital AEs, and laboratory results indicated no safety or tolerability issues with SPL7013 Gel, irrespective of circumcision status. There was no detectable absorption of SPL7013 into the plasma. Conclusions 3% SPL7013 Gel was safe and well tolerated, and comparable with placebo, when administered to the penis of both circumcised and uncircumcised men once daily for 7 days, with no evidence of systemic absorption or toxicity.

    Per- and polyfluoroalkyl substances (PFASs), used in food packaging and stain-resistant coatings, are suspected developmental toxicants that are ubiquitous and persistent in the environment. We measured plasma PFAS concentrations during early pregnancy (median = 9.7 weeks gestation) among 1645 women in the Boston-area Project Viva cohort, recruited during 1999–2002. We used multivariable linear regression to estimate associations of sociodemographic and perinatal predictors, including measures of pregnancy physiology (albumin, glomerular filtration rate (GFR)), with log-transformed plasma PFAS concentrations. Geometric mean concentrations for the four main PFASs, perfluorooctanesulfonate (PFOS), perfluorooctanoate (PFOA), perfluorohexanesulfonate (PFHxS) and perfluorononanoate (PFNA) were 25.4, 5.7, 2.5, and 0.6 ng/mL, respectively, comparable with general U.S. population concentrations during those years. Higher early pregnancy PFAS concentrations were associated with younger age (except PFNA), less educational attainment, nulliparity, no history of breastfeeding and higher prepregnancy body mass index in adjusted models. In addition, lower GFR was associated with 3–4% higher PFAS concentrations and higher albumin was associated with 4–6% higher PFAS concentrations. Our results show associations consistent (parity and breastfeeding) and less consistent (age and education) with previous studies. We also report associations with GFR and albumin, which were strongly related to PFAS concentrations and thus could confound estimates of PFAS–outcome associations in epidemiologic studies.

    Adolescents are seeking new references and experiences, which may involve attitudes of risk and exposure to accidents and violence from external causes. These events constitute a serious Public Health problem. The scope of this study was to analyze the occurrence of accidents by external causes in adolescents from 10 to 19 years of age attended at sentinel urgency and emergency services in Brazil. Data from the 2009 Surveillance System for Violence and Accidents (VIVA 2009) was analyzed in 74 emergency units in 23 state capitals and the Federal District. The findings revealed that 6,434 adolescents (89.8%) were victims of accidents and 730 (10.2 %) were victims of violence. The main causes of the accidents were falls and traffic accidents, and assaults were predominant in violence. For both accidents and violence, non-white male adolescents were predominant and the events occurred most frequently on the public highways. A marked increase was detected, with hospitalization of victims of violence between 15 and 19 years of age. Understanding the epidemiological reality of external causes among adolescents represents an important tool for health prevention and promotion policies and the culture of peace seeking to reduce morbidity and mortality.

    Understanding the characteristics and magnitude of accidents and violence due to external causes in children from 0 to 9 years of age is becoming ever more important in Public Health. The scope of this paper was to analyze emergency care for accidents due to external causes in children. The Sentinel Urgency and Emergency Services of the Violence and Accident Vigilance System (VIVA Survey), performed in 74 urgency services in the Federal District and 23 State capitals in 2009 was used. Data of 7,123 children were analyzed: 6,897 (96.7%) victims of accidents and 226 (3.3%) of violence. In comparison with victims of violence, the visits for accidents were more frequent among white children from 2 to 5 years old occurring in the home (p < 0.05). Among the accidents, falls and burns predominated in the 0 to 1group, while traffic accidents were most frequent in the 6 to 9-year-old age group (p < 0.001). With respect to violence, the visits for neglect and physical assault predominated, respectively, in extreme age groups, with someone in the family being the perpetrator (p < 0.001). Information on the occurrence of external causes in children may support health promotion policies, besides guiding health professionals, teachers and families in the prevention of such causes.

    Positively surface-charged poly(lactide-co-glycolide) (PLGA)/Eudragit RL nanoparticles (NPs) were designed to increase retention time and sustain release profile in joints after intra-articular injection, by forming micrometer-sized electrostatic aggregates with hyaluronic acid, an endogenous anionic polysaccharide found in high amounts in synovial fluid. The cationic NPs consisting of PLGA, Eudragit RL, and polyvinyl alcohol were fabricated by solvent evaporation technique. The NPs were 170.1 nm in size, with a zeta potential of 21.3 mV in phosphate-buffered saline. Hyperspectral imaging (CytoViva(®)) revealed the formation of the micrometer-sized filamentous aggregates upon admixing, due to electrostatic interaction between NPs and the polysaccharides. NPs loaded with a fluorescent probe (1,1'-dioctadecyl-3,3,3',3' tetramethylindotricarbocyanine iodide, DiR) displayed a significantly improved retention time in the knee joint, with over 50% preservation of the fluorescent signal 28 days after injection. When DiR solution was injected intra-articularly, the fluorescence levels rapidly decreased to 30% of the initial concentration within 3 days in mice. From these findings, we suggest that PLGA-based cationic NPs could be a promising tool for prolonged delivery of therapeutic agents in joints selectively.

    The clinical applications of silver nanoparticles (AgNPs) remain limited due to the lack of well-established methodologies for studying their nanokinetics. Hereby, the primary goal is to adapt a suite of analytical-based methodologies for examining the in vitro absorption, distribution, metabolism, and elimination of AgNPs. Vero 76 and HEK 293 cells are exposed to ≈10-nm spherical AgNPs(+) and AgNPs(-) at relevant concentrations (0-300 µg mL(-1) ) and times (4-48 h). Absorption: Inductively coupled plasma optical emission spectroscopy (ICP-OES) demonstrates that the two AgNP formulations are not bioequivalent. For example, different bioavailabilities (Cmaximum < 20.7 ± 4% and 6.82 ± 0.4%), absorption times (Tmaximum > 48 and ≈24 h), and absorption rate laws (first- and zeroth-order at 300 µg mL(-1) ) are determined in Vero 76 for AgNPs(+) and AgNPs(-) , respectively. Distribution: Raman and CytoViva hyperspectral imaging show different cellular localizations for AgNPs(+) and AgNPs(-) . Metabolism: Cloud point extraction (CPE)-tangential flow filtration (TFF) reveal that ≤ 11% ± 4% of the administered, sublethal AgNPs release Ag(+) and contribute to the observed cytotoxicity. Elimination: ICP-OES-CPE suggests that AgNPs are cleared via exocytosis. © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Oral cavity is a doorway for a variety of products containing titanium dioxide (TiO2 ) nanoparticles (NPs) (nano-TiO2 ) such as food additives, oral healthcare products and dental materials. Their potential to penetrate and affect normal human oral mucosa is not yet determined. To evaluate the ability of nano-TiO2 to penetrate the in vitro reconstructed normal human buccal mucosa (RNHBM). RNHBM was generated from primary normal human oral keratinocytes and fibroblasts isolated from buccal oral mucosa of healthy patients (n = 6). The reconstructed tissues were exposed after 10 days to clinically relevant concentrations of spherical or spindle rutile nano-TiO2 in suspension for short (20 min) and longer time (24 h). Ultrahigh-resolution imaging (URI) microscopy (CytoViva(™) , Auburn, AL, USA) was used to assess the depth of penetration into reconstructed tissues. Ultrahigh-resolution imaging microscopy demonstrated the presence of nano-TiO2 mostly in the epithelium of RNHBM at both 20 min and 24-h exposure, and this was shape and doze dependent at 24 h of exposure. The depth of penetration diminished in time at higher concentrations. The exposed epithelium showed increased desquamation but preserved thickness. Nano-TiO2 is able to penetrate RNHBM and to activate its barrier function in a doze- and time-dependent manner. © 2016 The Authors.

    Revealing the lung tumor genome has directed the current treatment strategies toward targeted therapy. First line treatments targeting the genome of lung tumor cells have been approved and are on the market. However, they are limited by the small number of patients with the current investigated genetic mutations. Novel treatment administration modalities have been also investigated in an effort to increase the local drug deposition and disease control. In the current study, we investigated the safety of the new nonviral vector 2-diethylaminoethyl-dextran methyl methacrylate copolymer (DDMC; Ryujyu Science), which belongs to the 2-diethylaminoethyl-dextran family by aerosol administration. Thirty male BALBC mice, 2 month old, were included and divided into three groups. However, pathological findings indicated severe emphysema within three aerosol sessions. In addition, the CytoViva technique was applied for the first time to display the nonviral particles within the pulmonary tissue and emphysema lesions, and a spectral library of the nonviral vector was also established. Although our results in BALBC mice prevented us from further investigation of the DDMC nonviral vector as a vehicle for gene therapy, further investigation in animals with larger airways is warranted to properly evaluate the safety of the vector.

    Staphylococcus aureus (S. aureus)-specific bacteriophage was used as a probe for detection of methicillin-resistant S. aureus (MRSA) in aqueous solution using a novel optical method. Biorecognition phage monolayers transferred to glass substrates using Langmuir-Blodgett (LB) technique were exposed individually to MRSA in solution at logarithmic concentrations ranging from 10(6) to 10(9)cfu/ml, and observed for real-time binding using a CytoViva optical light microscope system. Results indicate that LB monolayers possessed high levels of elasticity (K), measuring 22 and 29 mN/m for 10(9) and 10(11)pfu/ml phage concentrations, respectively. Near-instantaneous MRSA-phage binding produced 33+/-5%, 10+/-1%, 1.1+/-0.1%, and 0.09+/-0.01% coverage of the substrate that directly correlated to a decrease in MRSA concentrations of 10(9), 10(8), 10(7), and 10(6)cfu/ml. The exclusive selectivity of phage monolayers was verified with Salmonella enterica subsp. enterica serovar typhimurium (S. typhimurium) and Bacillus subtilis.

    Background This article records the traditional knowledge of crab gatherers in the city of Conde, in the North Coast Region of Bahia State, Northeastern Brazil. Methods Data on biological and ecological aspects of economically important brachyuran crustaceans have been obtained from semi-structured interviews and in loco observations conducted from September 2007 to December 2009. A total of 57 fishermen of both genders, aged between 10 and 78 years have been interviewed (individually or collectively) in different contexts; interviewees were asked about aspects such as external morphology, life cycle, trophic ecology, and spatial and temporal distribution of the major economically important brachyuran crustaceans in the region. Seven fishing communities were visited: Siribinha, Sítio do Conde, Poças, Ilha das Ostras, Cobó, Buri and Sempre Viva. Data were analyzed by comparing the information provided by participants with those from the specialized academic literature. Results The results show that artisanal fishermen have a wide ranging and well-grounded knowledge on the ecological and biological aspects of crustaceans. Crab gatherers of Conde know about growth and reproductive behavior of the animals they interact with, especially with regard to the three major biological aspects: “molt”, “walking dance” and “spawning”. Conclusion This knowledge constitutes an important source of information that should be considered in studies of management and sustainable use of fishery resources in the North Coast Region of Bahia State.

    Injuries resulting from motorcycle road traffic accidents are an important public health issue in Brazil. This study aimed to describe the characteristics of motorcyclists involved in traffic accidents attended in public urgent and emergency services in the state capitals and the Federal District. This is a cross-sectional study based on data from the Violence and Accident Surveillance System (VIVA Survey) in 2014. Data were analyzed according to sociodemographic, event and attendance characteristics. Proportional differences between genders were analyzed by chi-square test (Rao-Scott) with 5% significance level. Motorcyclist-related attendances (n = 9,673) reported a prevalence of men (gender ratio = 3.2), young people aged 20-39 years (65.7%), black / brown (73.6%), paid work (76.4%). Helmet use was reported by 79.1% of the victims, 13.3% had consumed alcohol in the six hours prior to the accident, 41.4% of the events were related to the victim's work. Accidents were more frequent on weekends, in the morning and late afternoon. These characteristics can support the development of public accident prevention policies and health promotion.

    In the United States, annual influenza vaccination rates are suboptimal and are well below the national health objectives. Project VIVA mobilized community members and organizations to implement an influenza vaccination program in Harlem by administering vaccines in “non-traditional” venues, such as community-based organizations, pharmacies, and faith-based organizations (FBOs). FBOs have been recognized as important venues for health promotion initiatives within medically underserved communities. However, data regarding the extent of resources and interest in health promotion programs among FBOs are sparse. We conducted a telephone survey among 115 FBOs in three New York City neighborhoods with histories of low influenza immunization rates to identify the congregation’s health concerns, interest in serving as a community-based venue for influenza vaccinations, and existing resources for health programming. Twenty-six percent of the FBOs had an established health ministry, while 45% expressed interest in developing one. Seven percent included nurses among their health activities and 16.5% had contact with the local health department. Most FBOs expressed interest in common health promotions programs; 60% expressed interest in providing on-site influenza vaccination programs within their organization. Health programs within FBOs can be a point of access that may improve the health of their congregants as well as the larger community. PMID:22623183

    Early diagnosis of infections with human immunodeficiency virus (HIV) is needed - especially among key populations such as sex workers, transgender people, men who have sex with men and people who use drugs. The Brazilian Ministry of Health developed a strategy called Viva Melhor Sabendo ("live better knowing") to increase HIV testing among key populations. In partnership with nongovernmental organizations (NGOs), a peer point-of-care testing intervention, using an oral fluid rapid test, was introduced at social venues for key populations at different times of the day. Key populations in Brazil can have 40 times higher HIV prevalence than the general population (14.8% versus 0.4%). Legislation was reinterpreted, so that oral fluid rapid tests could be administered by any person trained in rapid testing by the health ministry. Between January 2014 and March 2015, 29 723 oral fluid tests were administered; 791 (2.7%) were positive. Among the key populations, transgender people had the greatest proportion of positive results (10.7%; 172/1612), followed by men who declared themselves as commercial sex workers (8.7%; 165/1889) and men who have sex with men (4.8%; 292/6055). The strategy improved access to HIV testing. Testing done by peers at times and locations suitable for key populations increased acceptance of testing. Working with relevant NGOs is a useful approach when reaching out to these key populations.

    Cytokines are considered to be involved in obesity-related metabolic diseases. Study objectives are to determine the heritability of circulating cytokine levels, to investigate pleiotropy between cytokines and obesity traits, and to present genome scan results for cytokines in 1030 Hispanic children enrolled in VIVA LA FAMILIA Study. Cytokine phenotypes included monocyte chemoattractant protein-1 (MCP-1), tumor necrosis factor-alpha (TNF-alpha), leptin, adiponectin, soluble intercellular adhesion molecule-1 (sICAM-1), transforming growth factor beta 1 (TGF-beta1), C-reactive protein (CRP), regulated upon activation, normal T-cell expressed and secreted (RANTES) and eotaxin. Obesity-related phenotypes included body mass index (BMI), fat mass (FM), truncal FM and fasting serum insulin. Heritabilities ranged from 0.33 to 0.97. Pleiotropy was observed between cytokines and obesity traits. Positive genetic correlations were seen between CRP, leptin, MCP-1 and obesity traits, and negative genetic correlations with adiponectin, ICAM-1 and TGF-beta1. Genome-wide scan of sICAM-1 mapped to chromosome 3 (LOD=3.74) between markers D3S1580 and D3S1601, which flanks the adiponectin gene (ADIPOQ). Suggestive linkage signals were found in other chromosomal regions for other cytokines. In summary, significant heritabilities for circulating cytokines, pleiotropy between cytokines and obesity traits, and linkage for sICAM-1 on chromosome 3q substantiate a genetic contribution to circulating cytokine levels in Hispanic children.

    I tumori metastatici in genere hanno una cattiva prognosi, con sopravvivenza breve e raramente sono candidabili al trattamento chirurgico. Nel caso dei carcinomi differenziati della tiroide, la prognosi è solitamente migliore, grazie alla possibilità di un approcio multidisciplinare e soprattutto al trattamento radiometabolico dei secodarismi, dopo l’asportazione del tumore primitivo. Il caso presentato riguarda una donna di 65 anni, che è giunta alla nostra osservazione per una tumefazione mandibolare, risultata successivamente una metastasi da carcinoma follicolare della tiroide, a partenza da un voluminoso gozzo cervico-mediastinico normofunzionante, con ulteriori secondarismi a livello polmonare. Dopo un accurato studio pre-operatorio la Paziente è stata sottoposta a resezione della mandibola sinistra con ricostruzione mediante una protesi metallica e a tiroidectomia totale. Successivamente è stata trattata con quattro cicli di terapia radiometabolica con buona risposta. La Paziente è viva, senza ulteriore progressione di malattia a un follow-up di quarantasei mesi. Anche nei casi di tumori differnziati della tiroide in fase metastatica, l’opzione chirurgica va presa in considerazione per consentire alle terapie complementari di migliorare la prognosi in termini di sopravvivenza.

    In the State of Minas Gerais, the Secondary Reference Viva Vida Centers (CVVRS) are one of the strategies deployed to tackle the problems in child health. This study sought to evaluate pediatric care provided in a CVVRS, using the guidelines defined when it was set up as a benchmark. A quantitative-qualitative approach was adopted, which included a cross-sectional study with stratified random sampling of 385 medical records of children registered with the program between 2007 and 2009, and analysis of focus groups with strategic actors of the initiative. There were divergences between the user profiles and the target audience in terms of age, hometown and clinical characteristics. Access and use of the service differed depending on the town, due to problems of misinformation concerning the proposal, difficulty of transportation and the fragility of the health network. The centers are considered an innovative and important initiative for the expansion and organization of the health network, though the intended logic is not effectively seen in practice. Interventions for articulation between the network services and adaptation of the agreed guidelines to the regional specificities are necessary.

    Objective We sought to identify modifiable risk factors for excessive gestational weight gain (GWG). Study Design We assessed associations of diet and physical activity with excessive gain among 1388 women from the Project Viva cohort study. Results 379 (27%) of women were overweight (BMI>=26kg/m2) and 703 (51%) experienced excessive GWG, according to Institute of Medicine guidelines. In multivariable logistic regression models, we found that intake of total energy (OR 1.10, 95%CI 1.00–1.22, per 500 kcal/day), dairy (1.08, 95%CI 1.00–1.17, per serving/day), and fried foods (OR 3.47, 95%CI 0.91–13.24, per serving/day) were directly associated with excessive GWG. First trimester vegetarian diet (0.46, 95%CI 0.28–0.78) and mid-pregnancy walking (0.91, 95%CI 0.82–1.00, per half-hour/day) and vigorous physical activity (0.76, 95%CI 0.60–0.97, per half-hour/day) were inversely associated with excessive GWG. Conclusion Healthful diet and greater physical activity are associated with reduced risk for excessive gestational weight gain. PMID:19467640

    Studies of polyamino acid formation pathways in the prebiotic condition are important for the study of the origins of life. Several pathways of prebiotic polyamino acid formation have been reported. Heating of monoammonium malate [1] and heating of amino acids in molten urea [2] are important pathways of the prebiotic peptide formation. The former case, globular structure called proteinoid microsphere is formed in aqueous conditions. The later case, polyamino acids are formed from unrestricted amino acid species. Heating of aqueous aspargine is also interesting pathway for the prebiotic polyamino acid formation, because polyamino acid formation proceeds in aqueous condition [3]. In this study, we analyzed the chemical structure of the proteinoids and related polyamino acids formed in the above three pathways using with mass spectrometer. In addition, their physical structures are analyzed by the electron and optical microscopes, in order to determine the self-organization abilities. We discuss the relation between the chemical and the physical structures for the origins of life. References [1] Harada, K., J. Org. Chem., 24, 1662 (1959), Fox, S.

    Prenatal folic acid exposure has been linked to higher risk of childhood asthma in countries that do not fortify the food supply with folic acid. This study seeks to examine this association in the United States, where the food supply is generally fortified with folic acid. Participants were 1279 mother-child pairs from Project Viva, an ongoing prospective birth cohort, with folic acid intake in pregnancy assessed through validated food frequency questionnaires. The primary outcome was physician-diagnosed asthma at mid-childhood. In an unadjusted logistic regression model, higher folic acid intake was associated with lower odds of asthma in mid-childhood (odds ratio [OR] 0.48; 95% CI 0.31-0.76). However, in the adjusted analysis this association was attenuated (adjusted OR [aOR] 0.80; 95% CI 0.49-1.33). Our results suggest that in the United States, where there is generalized folic acid fortification of food, maternal folic acid intake during pregnancy is not associated with asthma development in offspring.

    The scenario in medical education is changing with objective structured clinical examination (OSCE) being introduced as an assessment tool. Its successful implementation in anaesthesiology postgraduate evaluation process is still limited. We decided to to evaluate the effectiveness of OSCE and compare it to conventional examinations as formative assessment tools in anaesthesiology. We conducted a cross-sectional comparative study in defined population of anaesthesiology postgraduate students to evaluate the effectiveness of OSCE as compared to conventional examination as formative assessment tool in anaesthesiology. Thirty-five students appeared for the conventional examination on the 1(st) day and viva voce on the 2(nd) day and OSCE on the last day. At the conclusion of the assessment, all the students were asked to respond to the perception evaluation questionnaire. We analysed the perception of OSCE among the students. Results showed a positive perception of the objective structured physical examination (OSCE) as well as structured 9 (25.7%), fair 19 (54.2%) and unbiased 13 (37.1%) with more standardised scoring 9 (25.7%). The students perceived OSCE to be less stressful than other examination. Thirty-one (88.5%) students agreed that OSCE is easier to pass than conventional method and 29 (82.5%) commented that the degree of emotional stress is less in OSCE than traditional methods. OSCE is better evaluation tool when compared to conventional examination.

    Irritant contact dermatitis is caused by skin barrier damage. Vitamin E is an antioxidant that is commonly used in cosmetics to prevent photo-damage. To show the usefulness of reflectance confocal microscopy in the assessment of irritant skin damage caused by sodium lauryl sulfate (SLS) and of the protective action of vitamin E applied prior to skin irritation. Ten healthy volunteers were enrolled. Irritation was induced by the application of a patch test containing SLS 5% aq. for 24 h. Three sites were compared: one site on which a product with vitamin E was applied before SLS treatment, one site on which the same product was applied after SLS treatment, and one control site (SLS only). Each site was evaluated with reflectance confocal microscopy, providing in vivo tissue images at nearly histological resolution. We also performed a computerized analysis of the VivaStack® images. Reflectance confocal microscopy is able to identify signs of skin irritation and the preventive effect of vitamin E application. Reflectance confocal microscopy is useful in the objective assessment of irritative skin damage. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Skin-dedicated ex vivo confocal microscopy (EVCM) has so far mainly been employed to identify cutaneous tumours on freshly excised samples. We present two cases where EVCM has been used to diagnose cutaneous mucormycosis. The skin biopsies were evaluated by the skin-dedicated ex vivo confocal microscope VivaScope 2500(®) (MAVIG GmbH, Munich Germany) under both reflectance and fluorescence mode. Conventional direct optical examination on skin scraping and histological examination were later performed. Mucormycetes observed by EVCM presented as hyper-reflective elongated 20 μm in diameter structures with perpendicular ramifications. Fungi were found both under reflectance and fluorescence mode and were better visible with acridine orange under fluorescence EVCM. Conventional direct optical examination on skin scraping and histological examination found the same elongated and branching structures confirming the presence of Mucormycetes. Ex vivo confocal microscopy has both the advantages of being fast as the direct optical examination, and to be able to show the localisation of the fungi in the tissue like the histological examination. In our cases, EVCM allowed to rapidly confirm the clinical diagnosis of mucormycosis, which is essential for the treatment of this fungal infection. Further studies are needed to compare the performance of EVCM with the findings of conventional histological and mycological examinations. © 2015 John Wiley & Sons A/S.

    Gestational weight gain is important to assess for epidemiological and public health purposes: it is correlated with infant growth and may be related to maternal outcomes such as reproductive health and chronic disease risk. Methods commonly used to assess weight gain incorporate assumptions that are usually not borne out, such as a linear weight gain, or do not account for differential length of gestation. We introduce a novel method to assess gestational weight gain, the area under the weight gain curve. This is easily interpretable as the additional pound-days carried due to pregnancy and avoids many flaws in alternative assessments. We compare the performance of the simple difference, weekly gain, Institute of Medicine categories and the area under the weight gain curve in predicting birthweight and maternal weight retention at 6, 12, 24 and 36 months postpartum. The analytic sample comprises 2016 participants in Project Viva, an observational prospective cohort study of pregnant women in Massachusetts. For birthweight outcomes, none of the weight gain measures is a meaningfully superior predictor. For 6-month postpartum weight retention the simple difference is superior, while for 12-, 24- and 36-month weight retention the area under the weight gain curve is superior. These findings are plausible biologically: the same amount of weight gained early vs later in the pregnancy may reflect increased maternal fat stores. The timing of weight gain is reflected best in the area under the weight gain curve. Different methods of measuring gestational weight gain may be appropriate depending on the context.

All medical students from the third year onwards were surveyed. A self-administered anonymous questionnaire was designed to gather information on the preferred assessment method for course achievement. The preferred methods were also evaluated in relation to cognitive functions. Preference for specific exam format, in the form of multiple choices, short essay questions, or both, and the stated reasons for that preference, was also included in the questionnaire. Out of 310 questionnaires distributed, 238 were returned. Written tests, projects, portfolios, and take home exams were the preferred modes for assessing students' achievements in a course; oral tests including a viva voce were the least preferred type of assessment. Questions that tested the domains of 'understanding' and 'application' were the most preferred type while those entailing 'analysis' were the least preferred. Multiple choice question format was the most preferred type of question (68.7%) at both pre- and clinical stages. Students' assessments at the College of Medicine, King Faisal University, Saudi Arabia, do not use the full range of cognitive domains. The emphasis on higher domains for medical students' assessment incorporating critical thinking should increase as the students' progress through their medical courses.

Correspondence analysis was used to identify variables associated with the outcome violence against children. Victims were predominantly male. The most common form of violence was neglect/abandonment, followed by physical violence and sexual violence. The most common perpetrators were parents (ages zero to one and two to five years), followed by friends (ages six to nine years). The most common place of occurrence was the home. Notable levels of violence were observed at school, particularly among children aged between six and nine years. Neglect was most common in the age group zero to one year and two to five years, while physical violence was most common between children aged between six and nine years.

    Abstract We analyzed the accidents with Brazilian indigenous treated at urgent and emergency services of the Unified Health System (SUS). Data were obtained from the 2014 Viva Survey, which included 86 services from 24 capitals and the Federal District. The demographic profile of the indigenous, the event and the attendance were characterized. Most of the attended people were male in the 20-39 years age group. Falls and traffic accidents were the main reasons for attendance. Alcohol use was informed by 5.6% of the attended people, a figure that increases to 19.1% in traffic accidents, 26.1% among drivers and 22.8% among motorcyclists. There was a statistical difference between genders in relation to age, disability, place of occurrence of the event, work-related event and victim's condition in the traffic accident. We emphasize the importance of providing visibility to accidents with indigenous and engage them in the prevention of such events. Data reliability depends on the adequate completion in indigenous health information systems.

    Noninvasive determination of plaque vulnerability has been a holy grail of medical imaging. Despite advances in tomographic technologies , there is currently no effective way to identify vulnerable atherosclerotic plaques with high sensitivity and specificity. Computed tomography (CT) and magnetic resonance imaging (MRI) are widely used, but neither provides sufficient information of plaque properties. Thus, we are motivated to combine CT and MRI imaging to determine if the composite information can better reflect the histological determination of plaque vulnerability. Two human endarterectomy specimens (1 symptomatic carotid and 1 stable femoral) were imaged using Scanco Medical Viva CT40 and Bruker Pharmascan 16cm 7T Horizontal MRI / MRS systems. μCT scans were done at 55 kVp and tube current of 70 mA. Samples underwent RARE-VTR and MSME pulse sequences to measure T1, T2 values, and proton density. The specimens were processed for histology and scored for vulnerability using the American Heart Association criteria. Single modality-based analyses were performed through segmentation of key imaging biomarkers (i.e. calcification and lumen), image registration, measurement of fibrous capsule, and multi-component T1 and T2 decay modeling. Feature differences were analyzed between the unstable and stable controls, symptomatic carotid and femoral plaque, respectively. By building on the techniques used in this study, synergistic CT+MRI analysis may provide a promising solution for plaque characterization in vivo.

    Ubiquitous bryophyte species are reported from European, American and Asian ethnopharmacies. Some of their traditional medicinal uses are similar in distant and isolated cultures, and moreover, medicinal properties of some bryophytes are currently confirmed as justified by their chemical constituents. Aims of the work: we identify bryophytes listed in a medicinal and botanical work from 1600, and compare their medicinal applications (known in Europe between 1530-1600) with other ethnopharmacological data about these species and with modern pharmacological knowledge. This way we attempt to display origins of medicinal usage of bryophytes in Central Europe. Bryophyte species in bibliographical sources printed in Central Europe (starting from O. Brunfels' Herbarum vivae Eicones... Argentorati, 1530) were identified according to old and recent taxonomical references. Caspar Schwenckfeld's scientific output from 1600 was treated here as a summary of 16th-century knowledge about medicinal bryophytes. Central European pharmacy about the year 1600 was familiar with the following bryophytes: Marchantia polymorpha L., Polytrichum commune Hedw., P. formosum Hedw. and Funaria hygrometrica Hedw. Between 1530-1600 in Central Europe the number of medicinal bryophytes increased from 2 (Lichen sive Hepatica and Polytrichon) to 4. Pharmaceutical usage of them was similar as in other, distant ethnopharmacies. Further 2-4 mosses (Rhytidiadelphus loreus and Rh. squarrosus; Thuidium tamariscinum and Th. delicatulum) were recognised as non-medicinal. Copyright © 2015 Elsevier Ireland Ltd.

    SPL7013 is the sodium salt of a sulfonated dendrimer that has potent antiviral properties. VivaGel®, a topical gel containing 3% w/w SPL7013, has been shown to be safe and well-tolerated in human clinical studies. BufferGel® is a Carbopol®-based acidic buffering gel that enhances the natural protective action of the vagina to produce a broad-spectrum microbicidal environment. The positive attributes of both gels were combined into a combination vaginal microbicidal gel having dual mechanisms of action. A 3% w/w SPL7013 combination gel, pH 3.7, was developed and fully characterized, and was shown to have more than 2-fold greater acidic buffering capacity than BufferGel. Ultracentrifugation experiments demonstrated that SPL7013 was not sequestered or entropically trapped in the viscous gel, thereby confirming, along with viral challenge studies, that SPL7013 has sufficient mobility in the viscous gel to exert antiviral properties.

    Assessment of technical dexterity is currently the weakest issue in surgical evaluation. It is imperative to develop an objective exam that allows us to correct training deficiencies and abilities and to objectively feedback education programs and hospitals. The purpose of this study was to perform a correlation between theoretical knowledge and surgical skills. We performed a national pilot study in in surgeons certifying by the Mexican Board of Surgery in 2010. This was a two-stage study: written exam (stage I) and oral exam (viva voce) to all surgeons approving the written exam (stage II). In stage II we utilized an objective structured assessment of technical skills (OSATS) whose results were correlated with those of the written and oral exams. The assessment involved seven skill stations and a global rating scale to indicate correctly performed or not and a fail/pass exam, respectively. Sixty-two surgeons approved the written exam in two places. We found no statistical difference among skills in open surgery (bowel anastomosis, liver and vascular suture), laparoscopic surgery (grape pilling, cutting a circle and intracorporeal knot tying) and instrument identification. There was a statistically significant difference (p <0.001) when median values were compared between laparoscopic surgery vs. open surgery and the identification of surgical instruments. There was a correlation between theoretical knowledge and surgical skills. When applying an OSATS, we found a positive correlation between theoretical knowledge and surgical skills. This assessment proves to to be valid and reliable for the evaluation of surgical dexterity.

    The catastrophes induced by earthquakes are among the most devastating, causing an elevated number of human losses and economic damages. In spite of being exposed to a moderate and large earthquakes, and as a result of the slow tectonic rates, the Portuguese society is, in general, little aware of the seismic risk. Earthquakes can't be predicted and the only way of mitigating their consequences is to understand their genesis, propagation and their effects in society. Children play a determinant role in the establishment of a real and long-lasting "culture of prevention", both through action and new attitudes. As adults they will have a greater knowledge of natural phenomena as well of the effects of human actions and their consequences. Parents and other caregivers have a critical function in encouraging and supporting their learning at home, in school, and throughout community. Teachers also play an important role in this effort and can be valuable partners with parents in cultivating learning confidence and skills in school-age youth. In this presentation we will give an overview of the project W-Shake, a Parents-in-Science Initiative to promote the study of seismology and related subjects. This project, supported by the Portuguese "Ciência Viva" program, results from a direct cooperation between the parents association, science school-teachers and the seismology research group at Instituto Dom Luíz.

  6. "To-be-forgotten" statements become less true: Memory processes involved in selection and forgetting lead to truthfulness changes of ambiguous sentences.

    What happens when people try to forget something? What are the consequences of instructing people to intentionally forget a sentence? Recent studies employing the item-method directed forgetting paradigm have shown that to-be-forgotten (TBF) items are, in a subsequent task, emotionally devaluated relative to to-be-remembered (TBR) items, an aftereffect of memory selection (Vivas, Marful, Panagiotidou & Bajo, 2016). As such, distractor devaluation by attentional selection generalizes to memory selection. In this study, we use the item-method directed forgetting paradigm to test the effects of memory selection and inhibition on truth judgments of ambiguous sentences. We expected the relative standing of an item in the task (i.e., whether it was instructed to be remembered or forgotten) to affect the truthfulness value of that item, making TBF items less valid/truthful than TBR items. As predicted, ambiguous sentences associated with a "Forget" cue were subsequently judged as less true than sentences associated with a "Remember" cue, suggesting that instructions to intentionally forget a statement can produce changes in the validity/truthfulness of that statement. To our knowledge, this is the first study to show an influence of memory processes involved in selection and forgetting on the perceived truthfulness of sentences. © 2017 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

    Inotropic drugs are part of the treatment of heart failure; however, inotropic treatment has been largely debated due to the increased incidence of adverse effects and increased mortality. Recently levosimendan, an inotropic positive agent, has been proved to be effective in acute heart failure, reducing the mortality and improving cardiac and renal performance. We report the case of a 75-year-old woman with history of heart and renal failure and hip fracture. Levosimendan was used in preoperative preparation as an adjuvant therapy, to improve cardiac and renal function and to allow surgery. Copyright © 2014 Sociedade Brasileira de Anestesiologia.

    In the antibiotic era, aortic aneurysm is a rare complication of syphilis, what makes the diagnostic assumption even more difficult. Nonetheless, this condition should be suspected in patients with aortic aneurysm. Reports of aortic dissection complicating syphilitic aortitis have been distinctly rare in the literature, and their cause-effect relationship has not been definitely established. In this case report, we present a 62-year-old woman with aortic aneurysm and dissection associated with an unexpected diagnosis of syphilitic aortitis.

    The notion of mixed states is classically associated with descriptions and categories inherited from Kraepelin. However, simultaneous descriptions of depressive and manic manifestations can be traced back to ancient times. Semiology and definitions of these clinical associations have evolved across the times. We provide here a short insight on four distinct periods: Greek authors from ancient times, pre-Kraepelinian psychiatry (18th and 19th centuries), Kraepelin's conceptualization, and contemporary psychiatry (20th and 21st centuries).

    Oxytocin is the uterotonic agent of choice in the prevention and treatment of postpartum uterine atony. Nevertheless, there is no consensus on the optimal dose and rate for use in cesarean sections. The use of high bolus doses (e.g., 10IU of oxytocin) can determine deleterious cardiovascular changes for the patient, especially in situations of hypovolemia or low cardiac reserve. Furthermore, high doses of oxytocin for prolonged periods may lead to desensitization of oxytocin receptors in myometrium, resulting in clinical inefficiency.

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

    To assess whether there has been any improvement in the quality and quantity of randomized controlled trials (RCTs) in nationally published journals through the application of standardized and validated scores. We electronically selected all RCTs published in the two indexed Brazilian journals that focus on orthopedics, over the period 2000-2009: Acta Ortopédica Brasileira (AOB) and Revista Brasileira de Ortopedia (RBO). These RCTs were identified and scored by two independent researchers in accordance with the Jadad scale and the Cochrane Bone, Joint and Muscle Trauma Group score. The studies selected were grouped as follows: 1) publication period (2000-2004 or 2004-2009); 2) journal of publication (AOB or RBO). Twenty-two papers were selected: 10 from AOB and 12 from RBO. No statistically significant differences were found between the proportions (nRCT/nTotal of published papers) of RCTs published in the two journals (p = 0.458), or in the Jadad score (p = 0.722) and Cochrane score (p = 0.630). The relative quality and quantity of RCTs in the journals analyzed were similar. There was a trend towards improvement of quality, but there was no increase in the number of RCTs between the two periods analyzed.

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

    Objective To evaluate the evolution of indicators after the implementation of 21 Oral Healthcare Teams in the Family Health Strategy. Methods We used data from outpatient services of Oral Healthcare Teams to evaluate efficiency, access, percentage of absences and emergencies of oral healthcare professionals who worked in the partnership between the Sociedade Beneficente Israelita Brasileira Hospital Albert Einstein and the Secretaria Municipal de Saúde de São Paulo, during the period 2009-2011. Results Percentages of emergencies, income, and access showed a significant difference during the period analyzed, but no difference for percentage of absences was found. When monthly analysis was made, it is noteworthy that at the beginning of service implementation a fluctuation occurred, which may indicate that the work was consolidated over the months, becoming capable of receiving new professionals and increasing the population served. Comparison of the indicators in that period with the goals agreed upon between the Sociedade Beneficente Israelita Brasileira Hospital Albert Einstein and the Secretaria Municipal de Saúde de São Paulo made it possible to notice that the Oral Health Teams had a good performance. Conclusion The results showed that the goals were achieved reflecting the increasing number of professionals, the maturing of work processes in the Oral Health Teams, and optimization of the manpower available to perform the activities. Understanding these results will be important to guide the actions of Oral Health Teams for the following years and to assess the achievement of goals. PMID:25295445

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.

    We report the results of the self-evaluation of the Astronomy Bachelor Course of the Observatório do Valongo (OV), Universidade Federal do Rio de Janeiro (UFRJ). We have created, heuristically, data indicators capable of quantifying the impact of curriculum and institutional improvements on the student's background and career development in the last 30 years. It is remarkable that the institution in study: i) has undergone appreciable recent development; ii) has its graduation course as a long term investment and an essentially complete database on past professors and students; iii) is inserted in a young scientific Society (Sociedade Astronômica Brasileira - SAB), which has shown marked recent maturation and a large rate of growth. This enabled us to diagnose the evolution of the institution and its suitability to the different requirements of the astronomical career. We show that, in the hard science field, the increase of the number of graduated students and the decrease of the time spent as an undergraduate student are not sufficient, or even adequate, to evaluate the efficiency of education in science (Arany-Prado, L., 2003, Revista Brasileira de Ensino de Física, vol. 25, no. 1, 105-115; http://sbf.if.usp.br/rbef/Vol25/Num1).

    The II Brazilian Consensus Conference on Mechanical Ventilation was published in 2000. Knowledge on the field of mechanical ventilation evolved rapidly since then, with the publication of numerous clinical studies with potential impact on the ventilatory management of critically ill patients. Moreover, the evolving concept of evidence - based medicine determined the grading of clinical recommendations according to the methodological value of the studies on which they are based. This explicit approach has broadened the understanding and adoption of clinical recommendations. For these reasons, AMIB - Associação de Medicina Intensiva Brasileira and SBPT - Sociedade Brasileira de Pneumologia e Tisiologia - decided to update the recommendations of the II Brazilian Consensus. Physical therapy during mechanical ventilation has been one of the updated topics. This objective was described the most important topics on the physical therapy during mechanical ventilation. Systematic review of the published literature and gradation of the studies in levels of evidence, using the key words: mechanical ventilation and physical therapy. Recommendations on the most important techniques applied during mechanical ventilation. Physical therapy has a central role at the Intensive Care environment, mainly in patients submitted to a mechanical ventilatory support invasive or non invasive.

    "Piedra Dorada" was used to construct some of the most important heritage buildings in the cities of Úbeda and Baeza, in Jaén (Spain). UNESCO declared these cities World Heritage Cities in 2003. Although there are some Iberian or Roman ruins in which is already possible to see the use of this stone, it is from the XVI century when "Piedra Dorada" is extensively used in the construction of the main historical buildings. Some of well-known monuments are Vázquez de Molina Palace or chain Palace (XVI), San Salvador Church (Sacred Chapel of El Salvador) (XVI) o the Royal Colegiata of Santa María la Mayor de los Reales Alcázares (XVI) in Úbeda or the Justice House-The House of the Corregidor (XVI), the Saint Cathedral of the Natividad de Nuestra Señora (XVI) or Jabalquinto Palace (XV), in Baeza, among many others. "Piedra Dorada" includes several varieties with similar mineralogical and chemical characteristics, called "Piedra Viva" or "Jabaluna", more cemented and used mainly with structural purposes (ashlars, columns, etc) and "Piedra Franca", less cemented and used mainly with decorative purposes (façades, statues, etc). From a geological point of view, "Piedra Dorada" is a medium to fine grain size bioclastic calcarenite, part of the upper Miocene-Pliocene deposits of the Guadalquivir Basin (Post Orogenic Neogene Basins of the Betic Chains). It is made up of quartz (8% to 29%), calcite and/or dolomite (34% to 80%), and some feldspar. The intergranular calcite cement proportion varies between 7% and 33%. Physical and mechanical properties are highly variable depending on the variety. "Piedra Viva" has an open porosity of 5,2%, bulk density of 2,63 g/cm3, water absorption at atmospheric pressure between 1,5-2,7 %, compressive strength (dry) between 20,1-18,0 MPa, flexural resistance (dry) between 87,3-77,0 MPa and salt crystallization loss of mass of 2,5%. "Piedra Franca" has an open porosity of 24,3%, bulk density of 2,00 g/cm3, water absorption at atmospheric

    This study aimed to investigate the effectiveness of biofeedback cycling training on lower limb functional recovery, walking endurance, and walking speed for patients with chronic stroke. Thirty-one patients with stroke (stroke onset >3 months) were randomly assigned into two groups using a crossover design. One group (N = 16; mean: 53.6 ± 10.3 years) underwent conventional rehabilitation and cycling training (30 minutes/time, 5 times per week for 4 weeks), followed by only conventional rehabilitation for another 4 weeks. The other group (N = 15; mean: 54.5 ± 8.0 years) underwent the same training in reverse order. The bike used in this biofeedback cycling training was the MOTOmed viva2 Movement Trainer. Outcome measures included the lower extremity subscale of Fugl-Meyer assessment (LE-FMA), the 6-minute walk test (6MWT), the 10-meter walk test (10MWT), and the modified Ashworth scale (MAS). All participants were assessed at the beginning of the study, at the end of the 4(th) week, and at the end of the 8(th) week. Thirty participants completed the study, including the cycling training interventions and all assessments. The results showed that improvements in the period with cycling training were significantly better than the noncycling period in the LE-FMA (p < 0.05), 6MWT (p < 0.001), 10MWT (p < 0.001), and MAS (p < 0.001) scores. No significant carryover effects were observed. The improvements on outcome measures were significantly different between the cycling period and the noncycling period after adjusting for potential confounding factors in the multivariate analysis of variance (p < 0.001). The study result indicates that the additional 4-week biofeedback cycling training could lead to improved LE functional recovery, walking endurance, and speed for patients with chronic stroke.

    Objective This study evaluated the effect of two home-based exercise interventions (one culturally-adapted and one standard) on changes in Social Cognitive Theory (SCT) variables, physical activity (PA) and sedentary time (ST), and to determine the association between changes in SCT variables and changes in PA and ST in Hispanic breast cancer survivors. Method Project VIVA! was a 16-week randomized controlled pilot study to test the effectiveness and feasibility of a culturally-adapted exercise intervention for Mexican American and Puerto Rican breast cancer survivors in Houston, Texas and San Juan, Puerto Rico, respectively. Women (N=89) completed questionnaires on SCT variables, PA and ST and were then randomized to a 16-week culturally-adapted exercise program, a non-culturally adapted standard exercise intervention or a wait-list control group. Multiple regression models were used to determine associations between changes in SCT variables and changes in PA and ST. Results Participants were in their late 50s (58.5 ± 9.2 years) and obese (31.0 ± 6.5 kg/m2). Women reported doing roughly 34.5 minutes/day of PA and spending over 11 hours/day in sedentary activities. Across groups, women reported significant increases in exercise self-efficacy and moderate-intensity, vigorous-intensity, and total physical activity from baseline to follow-up (p<.05). Increased social support from family was associated with increases in vigorous-intensity PA. Increases in social modeling were associated with increases in moderate-intensity and total PA and decreases in ST from baseline to follow-up (p<.05). Conclusions Hispanic cancer survivors benefit from PA interventions that focus on increasing social support from family and friends and social modeling. PMID:26602701

    Topical microbicides are self-administered, prophylactic products for protection against sexually transmitted pathogens. A large number of compounds with known anti-human immunodeficiency virus type 1 (HIV-1) inhibitory activity have been proposed as candidate topical microbicides. To identify potential leads, an in vitro screening algorithm was developed to evaluate candidate microbicides in assays that assess inhibition of cell-associated and cell-free HIV-1 transmission, entry, and fusion. The algorithm advances compounds by evaluation in a series of defined assays that generate measurements of relative antiviral potency to determine advancement or failure. Initial testing consists of a dual determination of inhibitory activity in the CD4-dependent CCR5-tropic cell-associated transmission inhibition assay and in the CD4/CCR5-mediated HIV-1 entry assay. The activity is confirmed by repeat testing, and identified actives are advanced to secondary screens to determine their effect on transmission of CXCR4-tropic viruses in the presence or absence of CD4 and their ability to inhibit CXCR4- and CCR5-tropic envelope-mediated cell-to-cell fusion. In addition, confirmed active compounds are also evaluated in the presence of human seminal plasma, in assays incorporating a pH 4 to 7 transition, and for growth inhibition of relevant strains of lactobacilli. Leads may then be advanced for specialized testing, including determinations in human cervical explants and in peripheral blood mononuclear cells against primary HIV subtypes, combination testing with other inhibitors, and additional cytotoxicity assays. PRO 2000 and SPL7013 (the active component of VivaGel), two microbicide products currently being evaluated in human clinical trials, were tested in this in vitro algorithm and were shown to be highly active against CCR5- and CXCR4-tropic HIV-1 infection.

    Coastal protection is one of the main challenges for the Netherlands, where a large proportion of anthropogenic activity is located below sea level (both residential and economic). The Dutch government is implementing an innovative method of coastal replenishment using natural waves and winds to relocate sand from one side to the other of the country. This requires close monitoring of the spatio-temporal evolution of beaches in order to correctly model the future direction and amount of sand movement. To do so -on the onshore beach- we tested a Kite-Aerial Photography System for monitoring the beach dynamics at Zandmotor (http://www.dezandmotor.nl/en-GB/). The equipment used for data collection were a commercial DSLR camera (Nikon D7000 with a 20mm lens), gyro-levelled rig, Sutton Flowform 16 kite and Leica GNSS Viva GS10, with GSM connection to the Dutch geodetic network. We flew using a 115 m line with an average inclination of 40 to 45°; this gave a camera vertical distance of ~80 m and pixel size of ~20 mm. The methodology follows that of Smith et al. (2009), and of Paron & Smith (2013), applied to a highly dynamic environment with low texture and small relief conditions. Here we present a comparison of the quality of the digital elevation model (DEM) generated from the same dataset using two different systems: Structure from Motion (SfM) using Agisoft Photoscan Pro and traditional photogrammetry using Leica Photograpmmetry Suite. In addition the outputs from the two data processing methods are presented, including both an image mosaic and DEM, and highlighting pros and cons of both methods. References Smith, M.

    Gait alterations are present in a high percentage of patients with multiple sclerosis (MS). They appear from early stages of the disease and can limit patients' capacity to perform basic activities of daily living, affecting their quality of life. Visual biofeedback cycling training appears to be a useful tool in treating these impairments. This study aims to evaluate the short-term effect of visual biofeedback cycling training on gait in patients with MS. A total of 61 patients with mild to moderate MS were randomly assigned to a control group and an intervention group. The intervention group received visual biofeedback cycling training (MOTOmed viva2 system) once per week for 3 months, and a home exercise program. The control group only received the home exercise program. Both groups were evaluated using the GAITRite(®) Walkway gait assessment system before the intervention, during the first month of the programme, and after the intervention. In the intervention group, the analysis revealed statistically significant differences between Functional Ambulation Profile (FAP) scores before and during the intervention (P=.014), and before and after the intervention (P=.002). A statistically significant improvement was observed in step length in the intervention group between pre- and post-intervention scores (P=.001) and between first-month and post-intervention scores (P=.004). Visual biofeedback cycling training improved specific gait parameters in the short term and appears to be a therapeutic option for gait retraining in patients with MS.

    Background The bronchodilator response (BDR) reflects the reversibility of airflow obstruction and is recommended as an adjunctive test to diagnose asthma. The validity of the commonly used definition of BDR, a 12% or greater change in FEV1 from baseline, has been questioned in childhood. Objectives We sought to examine the diagnostic accuracy of the BDR test by using 3 large pediatric cohorts. Methods Cases include 1041 children with mild-to-moderate asthma from the Childhood Asthma Management Program. Control subjects (nonasthmatic and nonwheezing) were chosen from Project Viva and Home Allergens, 2 population-based pediatric cohorts. Receiver operating characteristic curves were constructed, and areas under the curve were calculated for different BDR cutoffs. Results A total of 1041 cases (59.7% male; mean age, 8.9 ± 2.1 years) and 250 control subjects (46.8% male; mean age, 8.7 ± 1.7 years) were analyzed, with mean BDRs of 10.7% ± 10.2% and 2.7% ± 8.4%, respectively. The BDR test differentiated asthmatic patients from nonasthmatic patients with a moderate accuracy (area under the curve, 73.3%). Despite good specificity, a cutoff of 12% was associated with poor sensitivity (35.6%). A cutoff of less than 8% performed significantly better than a cutoff of 12% (P = .03, 8% vs 12%). Conclusions Our findings highlight the poor sensitivity associated with the commonly used 12% cutoff for BDR. Although our data show that a threshold of less than 8% performs better than 12%, given the variability of this test in children, we conclude that it might be not be appropriate to choose a specific BDR cutoff as a criterion for the diagnosis of asthma.

    The effect of maternal attempt to lose weight during the postpartum period on later child weight has not been explored. Among 1,044 mother-infant pairs in Project Viva, we estimated longitudinal associations of maternal attempt to lose weight during the postpartum period with child weight and adiposity at age 3 years and examined differences in associations by type of weight loss strategy used. Using covariate-adjusted linear and logistic regression models, we estimated associations before and after adjusting for maternal weight-related variables including prepregnancy BMI. At 6 months postpartum, 53% mothers were trying to lose weight. At age 3 years, mean (s.d.) child BMI z-score was 0.44 (1.01) and 8.9% of children were obese. Children whose mothers were trying to lose weight at 6 months postpartum had higher BMI z-scores (0.30 (95% confidence interval (CI) 0.18, 0.42)) and were more likely to be obese (3.0 (95% CI 1.6, 5.8)) at 3 years of age. Addition of maternal prepregnancy BMI to the models attenuated but did not eliminate the associations seen for BMI z-score (0.24 (95% CI 0.12, 0.36) and obesity (2.4 (95% CI 1.2, 4.7)). Attempting to lose weight by exercising alone was the only weight loss strategy that consistently predicted higher child BMI z-score (0.36 (95% CI 0.14, 0.58)) and odds of obesity (6.0 (95% CI 2.2, 16.5)) at age 3 years. In conclusion, we observed an association between maternal attempt to lose weight at 6 months postpartum, particularly through exercise alone, measured using a single item and child adiposity at age 3 years. This association should be thoroughly examined in future studies.

    The endometrial receptivity is a complex of structure-functional characteristics of endometrium with clear temporal and spatial constants, conditioning the ability of endometrium to the implantation. The aim of our research was a studying of morphological and molecular aspects of the endometrial receptivity disorders at chronic endometritis. The basic studied group included cases of chronic endometritis (CE) with unknown etiology (30 patients) and with CE under autoimmune thyroiditis (26 patients with presence of antithyroid antibodies--ATA). All patients had different disorders of reproductive function; some of them were infertile. More over 73% of all studied patients were of the 26-40 ages old. The control group was presented by endometrium of healthy surrogate mothers (10 cases). The research was done on the Pipelle biopsies of endometrium, which was taken in the secretory phase (the period of "implantation window"). For confirmation of the CE diagnosis, the endometrium of women with ATA was taken in the proliferative phase too. Morphological, immunohistochemical and statistical (nonparametric analysis of Mann-Whitney) methods were used. As the primary antibodies were used CD68, CD138, CD56, Ki-67, Apaf-1, LIE The structure analysis of pinopodes was carried out by stained paraffin slices (CytoViva Technologies Inc., Auburn, AL, USA) with using of the traditional and luminescent microscopy (the definition is over 100 nm). Structure and molecular changes of endometrium at CE include inflammatory infiltration, fibroblastic reactions and alteration of extracellular matrix; apoptosis of functional layer leading to its insusceptibility to the regulatory signals. Disorders of endometrial remodeling in the "implantation window" determine the result of implantation and can be reason of the infertility. The reduced receptivity at CE is characterized by decrease of mature pinopodes and low expression of LIF in the surface epithelium.

    Among US racial/ethnic minority women, we examined associations between maternal experiences of racial discrimination and child growth in the first 3 years of life. We analyzed data from Project Viva, a pre-birth cohort study. We restricted analyses to 539 mother-infant pairs; 294 were Black, 127 Hispanic, 110 Asian and 8 from additional racial/ethnic groups. During pregnancy, mothers completed the Experiences of Discrimination survey that measured lifetime experiences of racial discrimination in diverse domains. We categorized responses as 0, 1-2 or ≥3 domains. Main outcomes were birth weight for gestational age z-score; weight for age (WFA) z-score at 6 months of age; and at 3 years of age, body mass index (BMI) z-score. In multivariable analyses, we adjusted for maternal race/ethnicity, nativity, education, age, pre-pregnancy BMI, household income and child sex and age. Among this cohort of mostly (58.2%) US-born and economically non-impoverished mothers, 33% reported 0 domains of discrimination, 33% reported discrimination in 1-2 domains and 35% reported discrimination in ≥3 domains. Compared with children whose mothers reported no discrimination, those whose mothers reported ≥3 domains had lower birth weight for gestational age z-score (β -0.25; 95% CI: -0.45, -0.04), lower 6 month WFA z-score (β -0.34; 95% CI: -0.65, -0.03) and lower 3-year BMI z-score (β -0.33; 95% CI: -0.66, 0.00). In conclusion, we found that among this cohort of US racial/ethnic minority women, mothers' report of experiencing lifetime discrimination in ⩾ 3 domains was associated with lower fetal growth, weight at 6 months and 3-year BMI among their offspring.

    Animal models indicate that exposure to choline in utero improves visual memory through cholinergic transmission and/or epigenetic mechanisms. Among 895 mothers in Project Viva (eastern Massachusetts, 1999–2002 to 2008–2011), we estimated the associations between intakes of choline, vitamin B12, betaine, and folate during the first and second trimesters of pregnancy and offspring visual memory (measured by the Wide Range Assessment of Memory and Learning, Second Edition (WRAML2), Design and Picture Memory subtests) and intelligence (measured using the Kaufman Brief Intelligence Test, Second Edition (KBIT-2)) at age 7 years. Mean second-trimester intakes were 328 (standard deviation (SD), 63) mg/day for choline, 10.5 (SD, 5.1) µg/day for vitamin B12, 240 (SD, 104) mg/day for betaine, and 1,268 (SD, 381) µg/day for folate. Mean age 7 test scores were 17.2 (SD, 4.4) points on the WRAML 2 Design and Picture Memory subtests, 114.3 (SD, 13.9) points on the verbal KBIT-2, and 107.8 (SD, 16.5) points on the nonverbal KBIT-2. In a model adjusting for maternal characteristics, the other nutrients, and child's age and sex, the top quartile of second-trimester choline intake was associated with a child WRAML2 score 1.4 points higher (95% confidence interval: 0.5, 2.4) than the bottom quartile (P-trend = 0.003). Results for first-trimester intake were in the same direction but weaker. Intake of the other nutrients was not associated with the cognitive tests administered. Higher gestational choline intake was associated with modestly better child visual memory at age 7 years. PMID:23425631

  9. A Possibility for Piece-wise Ignitions of a TCA Cycle in a Prebiotic Hydrothermal Environment

    We previously reported that formic and acetic acids were synthesized from the mixture of carbon dioxide and water in the presence of heated metal oxide serving as a catalyst (1). Fixation of carbon dioxide and monoxide could have been conceivable in the hydrothermal environment in the primitive ocean. We then considered a possibility of synthesizing major metabolites appearing in a TCA cycle in prebiotic conditions. Focused in this attempt was the vicinity of hydrothermal vents in the primitive ocean. We used a flow reactor to simulate hydrothermal circulation of seawater through hot vents (2). The experimental conditions we chose were that the hot chamber at 200 °C was connected to the cold chamber at 0 °C through a thin nozzle of its diameter 0.8 mm. The total volume of the reaction solution was 500 mL. The fluid was circulated through the flow reactor at the rate of 8 mL / min. As an initial attempt, we prepared the solution of acetic and formic acids. When iron chloride and copper sulfide were present in the solution, the products precipitated on the filter placed in the low-temperature chamber included di-carboxylic acids such as malic acid. We then proceeded to the reaction solution dissolving three different kinds of carboxylic acids, namely, succinate, fumarate, and oxoglutarate. We found that malic acid was in the solution after the operation of the flow-reactor. Formation and transformation of carboxylic acids were observed in our flow reactor. These observations, when combined together, may suggest a possibility of piece-wise ignitions of a TCA cycle even in the prebiotic ocean on the primitive earth. References (1) R. Terada, E. Imai, H.

    To examine the tracking and significance of beverage consumption in infancy and childhood. Among 1163 children in Project Viva, we examined associations of fruit juice and water intake at 1 year (0 oz, 1-7 oz [small], 8-15 oz [medium], and ≥16 oz [large]) with juice and sugar-sweetened beverage (SSB) intake and BMI z-score during early (median 3.1 years) and mid-childhood (median 7.7 years). In covariate adjusted models, juice intake at 1 year was associated with greater juice and SSB intake during early and mid-childhood and also greater adiposity. Children who drank medium and large amounts of juice at 1 year had higher BMI z-scores during both early (medium: β = 0.16 [95% CI = 0.01-0.32]; large: β = 0.28 [95% CI = 0.01-0.56]) and mid-childhood (medium: β = 0.23 [95% CI = 0.07-0.39]; large: β = 0.36 [95% CI = 0.08-0.64]). After covariate adjustment, associations between water intake at 1 year and beverage intake and adiposity later in childhood were null. Higher juice intake at 1 year was associated with higher juice intake, SSB intake, and BMI z-score during early and mid-childhood. Assessing juice intake during infancy could provide clinicians with important data regarding future unhealthy beverage habits and excess adiposity during childhood. © 2014 The Obesity Society.

    Objective To examine the tracking and significance of beverage consumption in infancy and childhood. Design and Methods Among 1163 children in Project Viva, we examined associations of fruit juice and water intake at 1 year (0 oz, 1–7 oz [small], 8–15 oz [medium], and ≥16 oz [large]) with juice and sugar-sweetened beverage (SSB) intake and BMI z-score during early (median 3.1 years) and mid-childhood (median 7.7 years). Results In covariate adjusted models, juice intake at one year was associated with greater juice and sugar sweetened beverages intake during early and mid-childhood and also greater adiposity. Children who drank medium and large amounts of juice at 1 year had higher BMI z-scores during both early (Medium: β=0.16 [95%CI=0.01, 0.32]; Large: β=0.28 [95%CI=0.01, 0.56]) and mid-childhood (Medium: β=0.23 [95%CI=0.07, 0.39]; Large: β=0.36 [95%CI=0.08, 0.64]). After covariate adjustment, associations between water intake at 1 year and beverage intake and adiposity later in childhood were null. Conclusions Higher juice intake at 1 year was associated with higher juice intake, sugar sweetened beverage intake, and BMI z-score during early and mid-childhood. Assessing juice intake during infancy could provide clinicians important data regarding future unhealthy beverage habits and excess adiposity during childhood. PMID:25328160

    To describe the profile of the reports of child and adolescent abuse in the state of São Paulo in 2009, and to analyze possible associated factors. A total of 4,085 reports regarding children and adolescents younger than 15 years recorded by the Domestic, Sexual, and Other Interpersonal Violence Surveillance System (Sistema de Vigilância de Violência Doméstica, Sexual e Outras Violências Interpessoais - VIVA) were analyzed using a logistic regression model. The females comprised 61.4% of the total cases. The most common age group among females was 10 to 14 years (38.8%) and among males was < 5 years (35.8%). Physical abuse accounted for 43.3% of cases in males, and sexual abuse cases accounted for 41.7% of cases in females. The main perpetrators of the abuse were parents (43.8% of the total) and acquaintances (29.4%). Male aggressors were 72.0% of the total. The abuse occurred at home in 72.9% of cases; repeated abuse was reported in 51.4% of cases. Differences between the cases of physical and sexual abuse: a) physical abuse - mostly males (50.9%), parents as perpetrators (48.4%), and women as perpetrators (42.8%), b) sexual abuse - mostly females (77.2%), known aggressors (48.4%), and men as perpetrators (96.1%). Variables associated with physical abuse: male gender (OR: 2.22), age 10-14 years (OR: 1.68), and parents as perpetrators (OR: 2.50). Sexual abuse was associated with female gender (OR: 2.84), age 5-9 years (OR: 1.66), and unknown authors (OR: 1.53). Public policies should guarantee that children and adolescents have a healthy and violence-free life. The analysis of the notifications is an important tool to establish prevention strategies.

    To examine associations of chronic insufficient sleep with diet and whether diet explains the sleep-adiposity relationship. In Project Viva, 1,046 parents reported children's sleep duration at 6 m and annually until midchildhood (7 y). The main exposure was a sleep curtailment score (6 m-7 y) ranging from 0 (maximal curtailment) to 13 (adequate sleep). In mid-childhood, parents reported children's diet; researchers measured height/weight. Multivariable linear regression assessed associations of sleep with diet (Youth Healthy Eating Index [YHEI]); sleep with BMI z-score adjusting for YHEI; and, secondarily, joint associations of sleep and YHEI with BMI. Mean (SD) sleep and YHEI scores were 10.21 (2.71) and 58.76 (10.37). Longer sleep duration was associated with higher YHEI in mid-childhood (0.59 points/unit sleep score; 95% CI: 0.32, 0.86). Although higher YHEI was associated with lower BMI z-score (-0.07 units/10-point increase; 95% CI: -0.13, -0.01), adjustment for YHEI did not attenuate sleep-BMI associations. Children with sleep and YHEI scores below the median (<11 and <60) had BMI z-scores 0.34 units higher (95% CI: 0.16, 0.51) than children with sleep and YHEI scores above the median. While parent-reported diet did not explain inverse associations of sleep with adiposity, both sufficient sleep and high-quality diets are important to obesity prevention. © 2015 The Obesity Society.

    This analysis proposes safety and performance goals for prospective single-arm trials of bare nitinol stents to treat patients with debilitating claudication associated with femoropopliteal (FP) atherosclerotic lesions. To date there have been no analyses of clinical trials data to set efficacy and safety benchmarks for new bare nitinol stents in the treatment of claudication from FP disease. Industry has been reluctant to sponsor studies of nitinol stents due to logistical barriers. VIVA Physician's, Inc. (VPI) analyzed subject-level data from the PTA control arm of three randomized FDA device trials conducted by industry. Subjects with Rutherford category 2-4 claudication and FP lesion lengths 4-15 cm with 12 month duplex ultrasound (DUS) assessment were identified. These data were combined with the results of a survey of the medical literature (1990-2006) for similar subjects. Analysis of the industry derived control arm PTA data identified 116 patients (mean lesion length 8.7 cm) with a 12 month DUS defined FP patency of 28%. A similar cohort of 191 patients was identified from the medical literature in which the 12-month vessel patency equaled 37%; from these combined patient cohorts, expected vessel patency for PTA was estimated to equal 33%. Based on the PTA performance efficacy rate of 33% derived from industry clinical trial data and the medical literature, and the requirement that the bare nitinol stent 12-month efficacy performance goal be set to equal twice this rate, the patency efficacy goal equals 66%. Additional information is provided on safety and other reporting standards and stent integrity evaluation for bare metal stents. (c) 2007 Wiley-Liss, Inc.

    Water, in all its dimensions and scope, concerns humans as civilization, individuals and communities immersed in an environment that faces serious environmental threats and changes. The efficient way to deal with this crisis is education of present and future generations, breaking paradigms, creating awareness and new development models, seeking community groups and forces to empower their water resource and care, manage and renew it in an efficient and sustainable manner. The multiple uses of water in personal uses, irrigation, agro-industry and clean energy production, transforms this resource in a strategic element to any nation. With support from the Centro Nacional de Alta Tecnologia (CeNAT), it was possible to formulate the "Agenda Ambiental de Moravia", agreeing to be the "Consejo Tecnico de Fuerzas Vivas" (CTFV) from Moravia - articulated network of stakeholders - the one that coordinate all actions refered to water Resources, pollution and cleaner technologies and protected Areas. CeNAT and CTFV have developed distinguished efforts to improve the Moravians quality of life, and this has led the initiative of constitution of a whole education and training project in rescuing the Upper Basin of the Rio Tarcoles, through the implementation of an ecological - recreative garden ("Parque Comunitario Pulmon Verde de Moravia"), fostersing good use of natural resources, and also works as a platform for training and awareness program in Sustainable Development, based on "Hacia una Nueva Cultura del Agua" (powered through the United Nations by Dr. Pedro Arrojo Agudo and his " Feria de Aguas, Rios y Pueblos", presented in many countries). This initiative is projected to the national and international communities, through the "Water International Conference", which propel initiatives, laws and decisions which enable the development of Costa Rica and other countries under a sustainable model, focused on this essential component for life on the planet.

    This study evaluated the effect of two home-based exercise interventions (one culturally adapted and one standard) on changes in social cognitive theory (SCT) variables, physical activity (PA), and sedentary time (ST), and determined the association between changes in SCT variables and changes in PA and ST in Hispanic breast cancer survivors. Project VIVA! was a 16-week randomized controlled pilot study to test the effectiveness and feasibility of a culturally adapted exercise intervention for Mexican American and Puerto Rican breast cancer survivors in Houston, Texas and San Juan, Puerto Rico, respectively. Women (N = 89) completed questionnaires on SCT variables, PA, and ST and were then randomized to a 16-week culturally adapted exercise program, a non-culturally adapted standard exercise intervention or a wait-list control group. Multiple regression models were used to determine associations between changes in SCT variables and changes in PA and ST. Participants were in their late 50s (58.5 ± 9.2 years) and obese (31.0 ± 6.5 kg/m(2) ). Women reported doing roughly 34.5 min/day of PA and spending over 11 h/day in sedentary activities. Across groups, women reported significant increases in exercise self-efficacy and moderate-intensity, vigorous-intensity, and total PA from baseline to follow-up (p < 0.05). Increased social support from family was associated with increases in vigorous-intensity PA. Increases in social modeling were associated with increases in moderate-intensity and total PA and with decreases in ST from baseline to follow-up (p < 0.05). Hispanic cancer survivors benefit from PA interventions that focus on increasing social support from family and friends and social modeling. Copyright © 2015 John Wiley & Sons, Ltd.

Normative reference values for handgrip strength in Colombian schoolchildren: the FUPRECOL study. J Strength Cond Res 31(1): 217-226, 2017-The primary aim of this study was to generate normative handgrip (HG) strength data for 10 to 17.9 year olds. The secondary aim was to determine the relative proportion of Colombian children and adolescents that fall into established Health Benefit Zones (HBZ). This cross-sectional study enrolled 7,268 schoolchildren (boys n = 3,129 and girls n = 4,139, age 12.7 [2.4] years). Handgrip was measured using a hand dynamometer with an adjustable grip. Five HBZs (Needs Improvement, Fair, Good, Very Good, and Excellent) have been established that correspond to combined HG. Centile smoothed curves, percentile, and tables for the third, 10th, 25th, 50th, 75th, 90th, and 97th percentile were calculated using Cole's LMS method. Handgrip peaked in the sample at 22.2 (8.9) kg in boys and 18.5 (5.5) kg in girls. The increase in HG was greater for boys than for girls, but the peak HG was lower in girls than in boys. The HBZ data indicated that a higher overall percentage of boys than girls at each age group fell into the "Needs Improvement" zone, with differences particularly pronounced during adolescence. Our results provide, for the first time, sex- and age-specific HG reference standards for Colombian schoolchildren aged 9-17.9 years.

    Much remains unknown about the mammalian immune response to Giardia lamblia, a protozoan pathogen that causes diarrhoeal outbreaks. We fractionated protein extracts of G. lamblia trophozoites by Viva-spin centrifugation, DEAE ion exchange and gel filtration chromatography. Resultant fractions were screened for antigenic molecules by western blots analysis using anti-G. lamblia antibodies (Abs), resulting in identification of G. lamblia binding immunoglobulin protein (GlBiP). Maturation of mouse dendritic cells (DCs) in response to recombinant GlBiP (rGlBiP) was detected by increased expression of surface molecules such as CD80, CD86 and MHC class II; these mature DCs, produced pro-inflammatory cytokines (TNF-α, IL-12 and IL-6). Especially, the truncated rGlBiP containing the heat-shock protein 70 domain-induced cytokine production from mouse DCs. rGlBiP-induced DC activation was initiated by TLR4 in a MyD88-dependent way and occurred through activation of p38 and ERK1/2 MAPKs as well as increased activity of NF-κB and AP-1. Moreover, CD4(+) T cells stimulated with rGlBiP-treated DCs produced high levels of IL-2 and IFN-γ. Together, our results suggest that GlBiP contributes to maturation of DCs via activation of TLR4-MyD88-p38, ERK1/2 MAPK, NF-κB and AP-1. © 2014 John Wiley & Sons Ltd.

    Objective Our aim was to examine associations of breastfeeding duration and exclusivity in infancy with executive function, behavior, and social-emotional development in mid-childhood. Methods We studied 1037 participants in Project Viva, a pre-birth cohort that enrolled pregnant mothers from 1999-2002 and followed children to 7-10 years. Main exposures were: (1) duration of any breastfeeding in the first 12 months and (2) duration of exclusive breastfeeding in the first 6 months. Main outcomes were child executive function, behavior, and social-emotional development, assessed by (1) the Behavior Rating Inventory of Executive Function (BRIEF) and (2) the Strengths and Difficulties Questionnaire (SDQ), completed independently by parents and teachers. Higher scores indicate greater problems. Results In linear regression models adjusted for sociodemographics, maternal intelligence, home environment, early child care, and maternal depression, longer breastfeeding duration was not associated with substantially better executive function, behavior, or social-emotional development. For example, for each additional month of any breastfeeding, the BRIEF Global Executive Composite score (parent) was 0.10 points higher (95% CI −0.01, 0.22) and the SDQ total difficulties score was 0.06 points higher (−0.01, 0.12). Breastfeeding duration was also not associated with BRIEF or SDQ subscales, nor was exclusive breastfeeding duration associated with any of the outcomes analyzed. Conclusion Despite beneficial effects on general intelligence, longer duration of any breastfeeding or of exclusive breastfeeding was not associated with better executive function, behavior, or social-emotional development in mid-childhood.

    Investigations have been conducted regarding the interference of nanoparticles (NPs) with different toxicological assay systems, but there is a lack of validation when conducting routine tests for nucleic acid isolation, quantification, integrity, and purity analyses. The interference of citrate-capped gold nanoparticles (AuNPs) was investigated herein. The AuNPs were added to either BEAS-2B bronchial human cells for 24 h, the isolated pure RNA, or added during the isolation procedure, and the resultant interaction was assessed. Total RNA that was isolated from untreated BEAS-2B cells was spiked with various concentrations (v/v%) of AuNPs and quantified. A decrease in the absorbance spectrum (220–340 nm) was observed in a concentration-dependent manner. The 260 and 280 nm absorbance ratios that traditionally infer RNA purity were also altered. Electrophoresis was performed to determine RNA integrity, but could not differentiate between AuNP-exposed samples. However, the spiked post-isolation samples did produce differences in spectra (190–220 nm), where shifts were observed at a shorter wavelength. These shifts could be due to alterations to chromophores found in nucleic acids. The co-isolation samples, spiked with 100 µL AuNP during the isolation procedure, displayed a peak shift to a longer wavelength and were similar to the results obtained from a 24 h AuNP treatment, under non-cytotoxic test conditions. Moreover, hyperspectral imaging using CytoViva dark field microscopy did not detect AuNP spectral signatures in the RNA isolated from treated cells. However, despite the lack of AuNPs in the final RNA product, structural changes in RNA could still be observed between 190–220 nm. Consequently, full spectral analyses should replace the traditional ratios based on readings at 230, 260, and 280 nm. These are critical points of analyses, validation, and optimization for RNA-based techniques used to assess AuNPs effects. PMID:25470814

    Television and insufficient sleep are associated with poor mental and physical health. This study assessed associations of TV viewing and bedroom TV with sleep duration from infancy to midchildhood. We studied 1864 children in Project Viva. Parents reported children's average daily TV viewing and sleep (at 6 months and annually from 1-7 years) and the presence of a bedroom TV (annually 4-7 years). We used mixed effects models to assess associations of TV exposures with contemporaneous sleep, adjusting for child age, gender, race/ethnicity, maternal education, and income. Six hundred forty-three children (35%) were racial/ethnic minorities; 37% of households had incomes ≤$70 000. From 6 months to 7 years, mean (SD) sleep duration decreased from 12.2 (2.0) hours to 9.8 (0.9) hours per day; TV viewing increased from 0.9 (1.2) hours to 1.6 (1.0) hours per day. At 4 years, 17% had a bedroom TV, rising to 23% at 7 years. Each 1 hour per day increase in lifetime TV viewing was associated with 7 minutes per day (95% confidence interval [CI]: 4 to 10) shorter sleep. The association of bedroom TV varied by race/ethnicity; bedroom TV was associated with 31 minutes per day shorter sleep (95% CI: 16 to 45) among racial/ethnic minority children, but not among white, non-Hispanic children (8 fewer minutes per day [95% CI: -19 to 2]). More TV viewing, and, among racial/ethnic minority children, the presence of a bedroom TV, were associated with shorter sleep from infancy to midchildhood.

    The authors investigated the rate of gestational weight gain associated with the lowest combined risk of 5 short- and longer-term maternal and child health outcomes for 2,012 mother-child pairs recruited in 1999-2002 into Project Viva, a prebirth cohort study in Massachusetts. Within each maternal prepregnancy body mass index (BMI, kg/m(2)) stratum, they performed a logistic regression analysis predicting all 5 outcomes, from which they determined the rate of gain at which average predicted prevalence of the adverse outcomes was the lowest. The mean rate of total gestational weight gain was 0.39 kg/week (standard deviation, 0.14). The prevalence of small for gestational age was 6%, large for gestational age was 14%, preterm delivery was 7%, substantial postpartum weight retention was 16%, and child obesity was 10%. The lowest predicted outcome prevalence occurred with a 0.28-kg/week gain for women whose BMI was 18.5-24.9, a 0.03-kg/week loss for a BMI of 25.0-29.9, and a 0.19-kg/week loss for a BMI of >or=30.0 kg/m(2)--the lowest observed weight changes in overweight and obese women. For normal-weight and overweight women, lowest-risk gains varied modestly with adjustment for maternal characteristics and with different outcome weightings. For obese women, the lowest-risk weight change was weight loss in all models. Recommendations for gestational weight gain for obese women should be revised.

    The evolution of the red-green visual subsystem in trichromatic primates has been linked to foraging advantages, specifically the detection of either ripe fruits or young leaves amid mature foliage, and to the intraspecific socio-sexual communication, namely the signal of the male rank, the mate choice and the reproductive strategies in females. New data should be added to the debate regarding the evolution of trichromatic color vision. Three catarrhine primates were observed to achieve this goal. The research was performed on captive groups of vervet monkeys (Chlorocebus aethiops), pig-tailed macaques (Macaca nemestrina) and chimpanzees (Pan troglodytes) housed at Parco Natura Viva - Garda Zoological Park (Italy). Using pairs of red-green bags containing the same hidden reward in comparable outdoor enclosures, we recorded the choices by observed individuals (n = 25) to investigate the role of color cues in choosing an object. The results indicate that chimpanzees used red color as cue to choose an object that contains food by showing a preference toward red objects; in contrast, vervet monkeys and pig-tailed macaques do not demonstrate a clear choice based on the color of the object. Our findings highlight the importance of the foraging hypothesis but not rule out the potential role of the intraspecific socio-sexual communication and may serve to add useful information to the debate regarding the adaptive value of the evolution of color vision in order to fill a phylogenetic gap from Old World monkeys to humans. Future studies should address the role of socio-sexual communication, such as the selection of the reproductive partner of both high genetic quality and with compatible genes, to determine how this influenced the evolution of color vision in non-human primates.

Future studies should address the role of socio-sexual communication, such as the selection of the reproductive partner of both high genetic quality and with compatible genes, to determine how this influenced the evolution of color vision in non-human primates.

    Objective To examine the extent to which infant television viewing is associated with language and visual motor skills at 3 years of age. Measures We studied 872 children who were participants in Project Viva, a prospective cohort. The design used was a longitudinal survey, and the setting was a multisite group practice in Massachusetts. At 6 months, 1 year, and 2 years, mothers reported the number of hours their children watched television in a 24-hour period, from which we derived a weighted average of daily television viewing. We used multivariable regression analyses to predict the independent associations of television viewing between birth and 2 years with Peabody Picture Vocabulary Test III and Wide-Range Assessment of Visual Motor Abilities scores at 3 years of age. Results Mean daily television viewing in infancy (birth to 2 years) was 1.2 (SD: 0.9) hours, less than has been found in other studies of this age group. Mean Peabody Picture Vocabulary Test III score at age 3 was 104.8 (SD: 14.2); mean standardized total Wide-Range Assessment of Visual Motor Abilities score at age 3 was 102.6 (SD: 11.2). After adjusting for maternal age, income, education, Peabody Picture Vocabulary Test III score, marital status, and parity, and child's age, gender, birth weight for gestational age, breastfeeding duration, race/ethnicity, primary language, and average daily sleep duration, we found that each additional hour of television viewing in infancy was not associated with Peabody Picture Vocabulary Test III or total standardized Wide-Range Assessment of Visual Motor Abilities scores at age 3. Conclusion Television viewing in infancy does not seem to be associated with language or visual motor skills at 3 years of age. PMID:19254972

    We implemented 6 confounding adjustment methods: 1) covariate-adjusted regression, 2) propensity score (PS) regression, 3) PS stratification, 4) PS matching with two calipers, 5) inverse-probability-weighting, and 6) doubly-robust estimation to examine the associations between the BMI z-score at 3 years and two separate dichotomous exposure measures: exclusive breastfeeding versus formula only (N = 437) and cesarean section versus vaginal delivery (N = 1236). Data were drawn from a prospective pre-birth cohort study, Project Viva. The goal is to demonstrate the necessity and usefulness, and approaches for multiple confounding adjustment methods to analyze observational data. Unadjusted (univariate) and covariate-adjusted linear regression associations of breastfeeding with BMI z-score were −0.33 (95% CI −0.53, −0.13) and −0.24 (−0.46, −0.02), respectively. The other approaches resulted in smaller N (204 to 276) because of poor overlap of covariates, but CIs were of similar width except for inverse-probability-weighting (75% wider) and PS matching with a wider caliper (76% wider). Point estimates ranged widely, however, from −0.01 to −0.38. For cesarean section, because of better covariate overlap, the covariate-adjusted regression estimate (0.20) was remarkably robust to all adjustment methods, and the widths of the 95% CIs differed less than in the breastfeeding example. Choice of covariate adjustment method can matter. Lack of overlap in covariate structure between exposed and unexposed participants in observational studies can lead to erroneous covariate-adjusted estimates and confidence intervals. We recommend inspecting covariate overlap and using multiple confounding adjustment methods. Similar results bring reassurance. Contradictory results suggest issues with either the data or the analytic method. PMID:25171142

    Objective To determine whether the quantity and type of milk (whole, 2%, or 1%/skim) consumed at age 2 is associated with adiposity at age 3. Design We assessed milk and dairy intake at age 2 with food frequency questionnaires completed by mothers. Our primary outcomes were body mass index (BMI) z-score and overweight at age 3 years, defined as BMI (kg/m2) for age and sex ≥ 85th percentile. Subjects 852 preschool-aged children in the prospective US cohort Project Viva. Statistical Analysis We used linear and logistic regression models, adjusting for maternal BMI and education, paternal BMI, and child age, sex, race/ethnicity, intake of energy, non-dairy beverages, TV-viewing, and BMI z-score at age 2 years. Results At age 2 years, mean (SD) milk intake was 2.6 (1.2) servings per day. Higher intake of whole milk at age 2, but not low-fat milk, was associated with a slightly lower BMI z-score (−0.09 unit per daily serving [95% CI −0.16, −0.01]) at age 3; when restricted to children with a normal BMI (5th to < 85th %ile) at age 2, the association was null (−0.05 unit per daily serving [95%CI −0.13, 0.02]). Intake of milk at age 2, whether full or low-fat, was not associated with risk of incident overweight at age 3. Neither total milk nor total dairy intake at age 2 was associated with BMI z-score or incident overweight at age 3. Conclusion Neither consuming more dairy products, nor switching from whole milk to low-fat milk at age 2, appears likely to prevent overweight in early childhood. PMID:20338282

  10. Environmental NGOs in Ecuador: an economic analysis of institutional change.

    Nongovernmental organizations (NGOs) in Latin America have grown more rapidly than has our understanding of the economic and political implications of this major institutional change. In Ecuador, between 1984 and late 1992, at least 24 new environmental NGOs emerged. An economist does a case study of them, especially Fundacion Natura (FN) in Ecuador, to understand their role and behavior which are a large part of environmental politics in Latin America. NGOs are successful because the public sector cannot meet the countries' needs and donors want to help NGOs, thereby providing the demand. For example, FN has received funding from USAID, World Wildlife Fund, the International Union for the Conservation of Nature, and other groups. FN charges donors 15% to cover administrative costs while many other NGOs do not receive international funding for administrative costs. FN is well connected with the public sector which is supportive and beneficial. FN activities complement the public sector's efforts in the environment. Further, it is well connected with private industry from whom it receives financial support. It has been criticized for supporting industry on some environmental issues, however. In fact, its Cuenca chapter split from FN in 1984 to form Tierra Viva, because FN sided with industry when industry wanted to build on agricultural land in Cuenca. FN's relationship with USAID is strained. FN is successful because it employs quality personnel who are committed to FN objectives. Yet FN and other NGOs do not have the monetary incentives for efficient production. Most other NGOs are financially strapped and depend on volunteers. The more radical environmental NGOs do not accept donations from the private sector and do not want to work with government. Despite the influence donors have on NGOs, the NGOs' powerful presence and their environmental education programs have consequences beyond donor control (e.g., FN and USAID).

    In the last years, studies on captive greater flamingos have increased. Research on zoo animals is important to improve the knowledge on these species and to improve their ex-situ and in-situ conservation. The aim of the present study was to investigate the parental behaviour of a captive colony of greater flamingo hosted at Parco Natura Viva, an Italian zoological garden, to improve the knowledge on this species in zoos. In particular, the present study investigated and compared the parental care of females and males in 35 breeding pairs of greater flamingos. For each pair, we collected durations of parental care behaviour of both females and males, recording their position in relation to the nest (near the nest, on the nest, away from the nest) and individual and social behaviours performed. First, both partners were involved in parental care and displayed species-specific behaviours reported in the wild. The main results were that males spent more time than females on the nest (P = 0.010) and near it (P = 0.0001) and were more aggressive toward other flamingos than females, both when sitting on the nest (P = 0.003) and when near the nest (P = 0.0003). Therefore, male flamingos seem to be more involved in incubation duties and nest protection than females. This kind of research is important not only to expand the knowledge on bird species such as flamingos, but also to improve their husbandry and breeding in controlled environment. Indeed, understanding animal behaviour allows us to gain insights into their individual and social needs, addressing potential animal welfare issues.

    Assessing manual lateralization in non-human primates could be an optimal way to understand the adaptive value of this asymmetry in humans. Though many studies have investigated hand preferences in Old and New World monkeys and apes, fewer studies have considered manual lateralization in strepsirrhines, especially in experimental tasks. This study investigated hand preferences for a unimanual and a bimanual task of 17 captive ring-tailed lemurs (Lemur catta), housed at Parco Natura Viva (VR), Italy. The effect of age on handedness has been also investigated. The lemurs were tested on a unimanual task, in which subjects were restricted to using one hand to retrieve the food inside an apparatus, and on a bimanual task, in which lemurs had to use one hand to keep the apparatus door open while reaching with the other hand to retrieve the food inside it. At the population-level, our results revealed an asymmetrical hand use distribution, in particular a bias toward a right hand preference for food reaching in both the unimanual and the bimanual tasks. Furthermore, at the individual-level, the bimanual task seems to elicit a greater hand preference than the unimanual task. Results of this study underline the importance of experimental tasks in determining hand preference in strepsirrhines. Furthermore, as bimanual tasks elicited a stronger degree of lateralization, they appear to be more suited to investigate manual laterality. Finally, findings from this study highlight the presence of a right hand preference in ring-tailed lemurs, shedding new light on the evolution of human right handedness. Am. J.

    The coefficient of diffuse reflection and light transmission measurements in an optically thick layer of blood at atherosclerosis conditions under multiple scattering of light in the visual and nearest IR-spectra region (590 -900 nm) were measured for calculation of the absorption coefficients of the material of particles and surrounding medium K((lambda) ) and parameter Q (the latter parameter was defined by the sizes of erythrocytes and aggregates and by refraction coefficient of red cells relative to plasma at atherosclerosis). For the main quantitative spectroscopy of particles the K1((lambda) ) for known value of K((lambda) ) and the parameter Q determinations it is necessary to have the knowledge of relative volume part H occupied by particles. In the case of a high concentration of particles H >= 0.2 as it takes place in the blood the parameters Q and K((lambda) ) are in dependence of H (H - is hematocrit ration for the case of whole blood). It should be noted that spectroscopy of multiple scattering light can give some information out of main absorption bands with the higher accuracy and higher light scattering. The latter value provides the opportunity of determination of faint absorption bands which couldn't be achieved by other methods. The method proposed is characterized by absence of probe preparations, approach to in viva conditions, expressivity, and high informativity of each experiment. A many-fold investigation of the blood of healthy men in the spectral region 650 - 810 nm shows the electron spectrum of absorption of molecular hemoglobin hem is the most optically active blood spectra component K((lambda) ). The broadening of spectral investigations, as in short wave or long wave areas of the spectrum, by the use of multiple scattering methods for calculations of K((lambda) ) and Q((lambda) ) enlarges the number of chromophores studied.

    Background A dye-based method for determining applicator usage in microbicide trials has been developed to assess whether applicators have been exposed to vaginal fluid. Our objective was to evaluate this method on polypropylene HTI applicators which are being widely used in several effectiveness trials of microbicides. Methods Study participants enrolled in a clinical trial assessing SPL7013 (VivaGel) inserted gel intravaginally twice daily for 14 days and returned used and unused applicators. Prior to staining, smears were prepared from each participant-inserted applicator, Gram stained and assessed independently for the presence of vaginal cells and bacteria. Of the 169 participant-inserted applicators, 168 (99%) had vaginal cells identified by Gram stain. Participant-inserted applicators were stained with a 0.05% FD&C Blue Dye No. 1 solution and compared to 70 inserted positive control applicators and 70 unused negative control applicators. Intravaginally inserted applicators should stain turquoise, while unused applicators should not retain any stain. The individual responsible for labeling and preparing the applicators did not serve as an evaluator. Results Under optimized conditions, the sensitivity and specificity ranged from 81–95% and 86–93%, respectively for single use and unused applicators. The dye-based method was only 47–77% sensitive for participant-inserted applicators obtained from women using gel twice daily. Conclusion The dye test for HTI polypropylene applicators had a sensitivity of 47–95% depending on the evaluator and whether gel was present in the vagina. The sensitivity was decreased with multiple gel applications. The dye-based method cannot be recommended for HTI polypropylene applicators to monitor product adherence. PMID:19556930

    Ex-vivo confocal laser scanning microscopy (CLSM) offers rapid tissue examination. Current literature shows promising results in the evaluation of non-melanoma skin cancer but little is known about presentation of melanocytic lesions (ML). This study evaluates ML with ex-vivo CLSM in comparison to histology and offers an overview of ex-vivo CLSM characteristics. 31 ML were stained with acridine orange or fluorescein and examined using ex-vivo CLSM (Vivascope2500(®) ; Lucid Inc; Rochester NY) in reflectance and fluorescence mode. Confocal images were correlated to histopathology. Benign and malignant features of the ML were listed and results were presented. Sensitivity and specificity were calculated using contingency tables. The ML included junctional, compound, dermal, Spitz and dysplastic nevi, as well as various melanoma subtypes. The correlation of the confocal findings with histopathology allowed the identification of different types of ML and differentiation of benign and malignant features. The study offers an overview of confocal characteristics of ML in comparison to histology. Ex-vivo CLSM does not reproduce the typical in-vivo horizontal mosaics but rather reflects the vertical histological presentation. Not all typical in-vivo patterns are detectable here. These findings may help to evaluate the ex-vivo CLSM as an adjunctive tool in the immediate intraoperative diagnosis of ML. Superficial spreading malignant melanoma. Histopathology (H&E stain; 200×) correlated to the reflectance (RM; 830 nm) and fluorescence mode (FM; 488 nm) in the ex-vivo CLSM (Vivablock(®) by VivaScan(®) , acridine orange). © 2016 WILEY-VCH Verlag GmbH & Co.

    In the state of the art finite element AHBMs for car crash analysis in the LS-DYNA software material named *MAT_MUSCLE (*MAT_156) is used for active muscles modeling. It has three elements in parallel configuration, which has several major drawbacks: restraint approximation of the physical reality, complicated parameterization and absence of the integrated activation dynamics. This study presents implementation of the extended four element Hill-type muscle model with serial damping and eccentric force-velocity relation including [Formula: see text] dependent activation dynamics and internal method for physiological muscle routing. Proposed model was implemented into the general-purpose finite element (FE) simulation software LSDYNA as a user material for truss elements. This material model is verified and validated with three different sets of mammalian experimental data, taken from the literature. It is compared to the *MAT_MUSCLE (*MAT_156) Hill-type muscle model already existing in LS-DYNA, which is currently used in finite element human body models (HBMs). An application example with an arm model extracted from the FE ViVA OpenHBM is given, taking into account physiological muscle paths. The simulation results show better material model accuracy, calculation robustness and improved muscle routing capability compared to *MAT_156. The FORTRAN source code for the user material subroutine dyn21.f and the muscle parameters for all simulations, conducted in the study, are given at https://zenodo.org/record/826209 under an open source license. This enables a quick application of the proposed material model in LS-DYNA, especially in active human body models (AHBMs) for applications in automotive safety.

    The authors aim was to examine associations of breastfeeding duration and exclusivity in infancy with executive function, behavior, and social-emotional development in mid-childhood. The authors studied 1037 participants in Project Viva, a prebirth cohort that enrolled pregnant mothers from 1999 to 2002 and followed children for 7 to 10 years. Main exposures were: (1) duration of any breastfeeding in the first 12 months and (2) duration of exclusive breastfeeding in the first 6 months. Main outcomes were child executive function, behavior, and social-emotional development, assessed by (1) the Behavior Rating Inventory of Executive Function (BRIEF) and (2) the Strengths and Difficulties Questionnaire (SDQ), completed independently by parents and teachers. Higher scores indicate greater problems. In linear regression models adjusted for sociodemographics, maternal intelligence, home environment, early child care, and maternal depression, longer breastfeeding duration was not associated with substantially better executive function, behavior, or social-emotional development. For example, for each additional month of any breastfeeding, the BRIEF Global Executive Composite score (parent) was 0.10 points higher (95% confidence interval, -0.01 to 0.22) and the SDQ total difficulties score was 0.06 points higher (-0.01, 0.12). Breastfeeding duration was also not associated with BRIEF or SDQ subscales, nor was exclusive breastfeeding duration associated with any of the outcomes analyzed. Despite beneficial effects on general intelligence, longer duration of any breastfeeding or of exclusive breastfeeding was not associated with better executive function, behavior, or social-emotional development in mid-childhood.

    Intravenous Urography (IVU) as a diagnostic modality has limitations in patients of obstructive uropathy with impaired renal function. Our aim was to study the technique and diagnostic accuracy of Magnetic Resonance Urography (MRU) in obstructive uropathy and to correlate the findings with IVU. Forty-eight patients, selected over a six-month period, based on mild to severe pelvicalyceal dilatation on screening ultrasonography, underwent an IVU; those having non-obstructive dilatation were excluded (18 patients). Thirty patients (age range 10 to 75 years) with definite obstructive dilatation underwent MRU. These were obtained using an open MRI unit (Siemens Magnetom Open Viva) with low-dose gadolinium-DTPA (0.01 mmol/kg body weight) using various MRI sequences. MRU studies were classified as 'excellent' or 'diagnostic' and data generated was compared with that of IVU. MRU studies were 'excellent' in twelve and 'diagnostic' in eighteen patients. Of the sixty pelvicalyceal systems (PCS) evaluated in thirty patients, there were thirty-seven calculi, nine pelvi-ureteric junction (PUJ) obstructions, six with impaired renal function, four malrotated kidneys and one each of horseshoe kidney, pancake kidney, pelvic mass (endometriomas), duplex moieties, ureterocele and vesico-ureteric reflux. MRU better depicted moderate-severe PCS dilatation, staghorn and urethral calculi, impaired renal function, extrinsic ureteric and PUJ obstruction. IVU better depicted small calculi and mild PCS dilatation. In these thirty patients of obstructive uropathy, low magnetic field, open MRI units and low-dose Gd-DTPA provided cost-effective MRU studies with excellent diagnostic utility. MRU scored over IVU in patients with moderate-severe dilatation, staghorn and urethral calculi, impaired renal function, extrinsic ureteric and PUJ obstruction.

    Nanomaterials, with dimensions in the 1-100 nm range, possess numerous potential benefits to society. However, there is little characterization of their effects on biological systems, either within the environment or on human health. The present study examines cellular interaction of aluminum oxide and aluminum nanomaterials, including their effect on cell viability and cell phagocytosis, with reference to particle size and the particle's chemical composition. Experiments were performed to characterize initial in vitro cellular effects of rat alveolar macrophages (NR8383) after exposure to aluminum oxide nanoparticles (Al2O3-NP at 30 and 40 nm) and aluminum metal nanoparticles containing a 2-3 nm oxide coat (Al-NP at 50, 80, and 120 nm). Characterization of the nanomaterials, both as received and in situ, was performed using transmission electron microscopy (TEM), dynamic light scattering (DLS), laser Doppler velocimetry (LDV), and/or CytoViva150 Ultra Resolution Imaging (URI)). Particles showed significant agglomeration in cell exposure media using DLS and the URI as compared to primary particle size in TEM. Cell viability assay results indicate a marginal effect on macrophage viability after exposure to Al2O3-NP at doses of 100 microg/mL for 24 h continuous exposure. Al-NP produced significantly reduced viability after 24 h of continuous exposure with doses from 100 to 250 microg/mL. Cell phagocytotic ability was significantly hindered by exposure to 50, 80, or 120 nm Al-NP at 25 microg/mL for 24 h, but the same concentration (25 microg/mL) had no significant effect on the cellular viability. However, no significant effect on phagocytosis was observed with Al2O3-NP. In summary, these results show that Al-NP exhibit greater toxicity and more significantly diminish the phagocytotic ability of macrophages after 24 h of exposure when compared to Al2O3-NP.

    The programme Ciencia Viva of the Portuguese Ministry of Science and Technology aims to create a greater understanding of science and science education amongst scientists, teachers, school children and the general public, each of whom is encouraged to cooperate and interact through regular contacts. The purpose is to improve practical, experimental and other forms of investigative work. To accomplish such work in schools, an overview of the state of science education worldwide is presented in terms of old and new traditions of the teaching of the physical and historical sciences the latter including the teaching of fieldwork. Traditional practices are compared with those established recently in various parts of the world in which more carefully considered understanding of the nature of science and science education has been established. In illustration of good practice, an outline is offered of the nature and rationale of two sets of curricular materials. These were designed by a team comprising staff members of the University of Aveiro and secondary school teachers and were trialled in schools. These activities are concerned with the internal rock cycle and the internal energy of the Earth in relation to plate tectonic theory. They are also related to the processes of weathering, erosion, transportation and deposition of sedimentary rocks and structures (like wave and current ripple marks) which were formed as part of the external rock cycle driven by the Sun's energy. The account concludes with an outline of the sub programme 'Geology in Summer', a fieldwork programme which introduces a holistic understanding of the workings of the outer part of the Earth to the general public. Students' perspectives and teachers' views about these experiences are generally very positive and are presented at the end. The whole programme was evaluated by an international team of scientists and science educators.

    Shorter sleep duration is linked to obesity, coronary artery disease, and diabetes. Whether sleep deprivation during the postpartum period affects maternal postpartum weight retention remains unknown. This study examined the association of sleep at 6 months postpartum with substantial postpartum weight retention (SPPWR), defined as 5 kg or more above pregravid weight at 1 year postpartum. The authors selected 940 participants in Project Viva who enrolled during early pregnancy from 1999 to 2002. Logistic regression models estimated odds ratios of SPPWR for sleep categories, controlling for sociodemographic, prenatal, and behavioral attributes. Of the 940 women, 124 (13%) developed SPPWR. Sleep distributions were as follows: 114 (12%) women slept < or =5 hours/day, 280 (30%) slept 6 hours/day, 321 (34%) slept 7 hours/day, and 225 (24%) slept > or =8 hours/day. Adjusted odds ratios of SPPWR were 3.13 (95% confidence interval (CI): 1.42, 6.94) for < or =5 hours/day, 0.99 (95% CI: 0.50, 1.97) for 6 hours/day, and 0.94 (95% CI: 0.50, 1.78) for > or =8 hours/day versus 7 hours/day (p = 0.012). The adjusted odds ratio for SPPWR of 2.05 (95% CI: 1.11, 3.78) was twofold greater (p = 0.02) for a decrease in versus no change in sleep at 1 year postpartum. Sleeping < or =5 hours/day at 6 months postpartum was strongly associated with retaining > or =5 kg at 1 year postpartum. Interventions to prevent postpartum obesity should consider strategies to attain optimal maternal sleep duration.

    Methyl-donor nutrients are substrates for methylation reactions involved in neurodevelopment processes. The role of maternal intake of these nutrients on cognitive performance of the offspring is poorly understood. We examined the associations of maternal intake of folate, vitamin B12, choline, betaine and methionine during the first and second trimesters of pregnancy, with tests of cognitive performance in the offspring at 3 years of age using data from 1210 participants in Project Viva, a prospective pre-birth cohort study in Massachusetts. We assessed nutrient intake with the use of food frequency questionnaires. Children's cognition at age 3 years was evaluated with the Peabody Picture Vocabulary Test III (PPVT-III) and visual-motor skills with the Wide Range Assessment of Visual Motor Abilities test. In multivariable models adjusting for potential sociobehavioural and nutritional confounders, for each 600 µg/day increment in total folate intake during the first trimester, PPVT-III score at age 3 years was 1.6 points [95% confidence interval (CI) 0.1, 3.1; P = 0.04] higher. There was a weak inverse association between vitamin B12 intake during the second trimester and PPVT-III scores [-0.4 points per 2.6 µg/day; 95% CI -0.8, -0.1; P = 0.01]. We did not find associations between choline, betaine or methionine and cognitive outcomes at this age. Results of this study suggest that higher intake of folate in early pregnancy is associated with higher scores on the PPVT-III, a test of receptive language that predicts overall intelligence, at age 3 years.

    When evaluating assessments, the impact on learning is often overlooked. Approaches to learning can be deep, surface and strategic. To provide insights into exam quality, we investigated the learning approaches taken by trainees preparing for the Australian and New Zealand College of Anaesthetists (ANZCA) Final Exam. The revised two-factor Study Process Questionnaire (R-SPQ-2F) was modified and validated for this context and was administered to ANZCA advanced trainees. Additional questions were asked about perceived value for anaesthetic practice, study time and approaches to learning for each exam component. Overall, 236 of 690 trainees responded (34%). Responses indicated both deep and surface approaches to learning with a clear preponderance of deep approaches. The anaesthetic viva was valued most highly and the multiple choice question component the least. Despite this, respondents spent the most time studying for the multiple choice questions. The traditionally low short answer questions pass rate could not be explained by limited study time, perceived lack of value or study approaches. Written responses suggested that preparation for multiple choice questions was characterised by a surface approach, with rote memorisation of past questions. Minimal reference was made to the ANZCA syllabus as a guide for learning. These findings indicate that, although trainees found the exam generally relevant to practice and adopted predominantly deep learning approaches, there was considerable variation between the four components. These results provide data with which to review the existing ANZCA Final Exam and comparative data for future studies of the revisions to the ANZCA curriculum and exam process.

    This article aims to describe and analyze reporting of violence against children from 0 to 9 years of age, issued by the public health services, in Brazil. Data from the Violence and Accident Surveillance System (Viva-SINAN) were used. The frequency of selected variables was calculated by age group (0-1; 2-5 and 6-9 years of age) as well as their Prevalence Ratios (PR). 17.900 cases were reported: 33% in the 0-1 year group; 35,8% in the 2-5 year group; and 31,2% in the 6-9 year group. Physical violence predominated among boys (PR: 1.22; CI 95%: 1,16-1,28 ); 6-9 years old (PR: 1,19; CI 95%: 1,12-1.27 ). Sexual violence predominated among girls, mulatto/afro-descendant (PR: 1.12; CI 95 %: 1.06 to 1.19 ); 6-9 years (PR: 4.63; CI 95%: 4.22- 5.08) with more chances of occurring at home (PR: 1.38 , CI: 95%: 1.29-1.48); psychological violence prevailed among girls, mulatto/afro-descendant (PR: 1.10; CI 95 %: 1.03-1.18 ), 6-9 years old (PR: 2.95; CI 95%: 2.69- 3.23), at home (PR: 1.40; CI 95%: 1.29-1.53); negligence predominated among boys (PR: 1.33 ; 95% CI: 1.27-1.39); 0-1 years and their parents were the most prevalent perpetrators.The results indicate the need to strengthen intersectoral actions aiming at extending the social protection and care network.

    Background Several studies have reported an association between use of over-the-counter antipyretics during pregnancy or infancy and increased asthma risk. An important potential limitation of these observational studies is confounding by indication. Objectives We investigated the association of antipyretic intake, 1) during pregnancy and 2) during the first year of life (infancy), with asthma-related outcomes, before and after controlling for early life respiratory infections. Methods We included 1490 mother-child pairs in Project Viva, a longitudinal pre-birth cohort study. We categorized prenatal acetaminophen exposure as the maximum intake (never, 1–9 or ≥ 10 times) in early or mid-pregnancy, and ibuprofen intake as presence or absence in early pregnancy. We expressed intakes of antipyretics in infancy as never, 1–5, 6–10, or >10 times. We examined the associations of acetaminophen and ibuprofen (per unit increase in exposure category) during pregnancy and infancy with wheeze, asthma and allergen sensitization in early (3–5 y) (n= 1419) and mid-childhood (7–10 y) (n= 1220). Results Unadjusted models showed an elevated asthma risk in early childhood for higher infant acetaminophen (OR 1.21, 95% CI 1.04, 1.41) and ibuprofen (OR 1.35, 95% CI 1.19, 1.52) intake. Controlling for respiratory infections attenuated estimates for acetaminophen (OR 1.03, 95% CI 0.88, 1.22) and ibuprofen (OR 1.19, 95% CI 1.05, 1.36). Prenatal acetaminophen was associated with increased asthma (OR 1.26, 95% CI 1.02, 1.58) in early but not mid-childhood. Conclusions Adjustment for respiratory infections in early life substantially diminished associations between infant antipyretics and early childhood asthma. Respiratory infections should be accounted for in studies of antipyretics and asthma, to mitigate bias due to confounding by indication. PMID:25441647

    Background: Melanocortin-4-receptor (MC4R) haploinsufficiency is the most common form of monogenic obesity; however, the frequency of MC4R variants and their functional effects in general populations remain uncertain. Objective: The aim was to identify and characterize the effects of MC4R variants in Hispanic children. Design: MC4R was resequenced in 376 parents, and the identified single nucleotide polymorphisms (SNPs) were genotyped in 613 parents and 1016 children from the Viva la Familia cohort. Measured genotype analysis (MGA) tested associations between SNPs and phenotypes. Bayesian quantitative trait nucleotide (BQTN) analysis was used to infer the most likely functional polymorphisms influencing obesity-related traits. Results: Seven rare SNPs in coding and 18 SNPs in flanking regions of MC4R were identified. MGA showed suggestive associations between MC4R variants and body size, adiposity, glucose, insulin, leptin, ghrelin, energy expenditure, physical activity, and food intake. BQTN analysis identified SNP 1704 in a predicted micro-RNA target sequence in the downstream flanking region of MC4R as a strong, probable functional variant influencing total, sedentary, and moderate activities with posterior probabilities of 1.0. SNP 2132 was identified as a variant with a high probability (1.0) of exerting a functional effect on total energy expenditure and sleeping metabolic rate. SNP rs34114122 was selected as having likely functional effects on the appetite hormone ghrelin, with a posterior probability of 0.81. Conclusion: This comprehensive investigation provides strong evidence that MC4R genetic variants are likely to play a functional role in the regulation of weight, not only through energy intake but through energy expenditure.

    To assess the student's attitude, perception and feedback on teaching-learning methodology and evaluation methods in pharmacology. One hundred and forty second year medical students studying at Smt. Kashibai Navale Medical College, Pune, were selected. They were administered a pre-validated questionnaire containing 22 questions. Suggestions were also asked regarding the qualities of good pharmacology teachers and modification in pharmacology teaching methods. Descriptive statistics were used and results were expressed as percentage. Majority of the students found cardiovascular system (49.25%) as the most interesting topic in pharmacology, whereas most of the students opined that cardiovascular system (60.10%), chemotherapy (54.06%) and central nervous system (44.15%) are going to be the most useful topics in internship. 48.53% students preferred clinical/patient-related pharmacology and 39.13% suggested use of audiovisual-aided lectures. Prescription writing and criticism of prescription were amongst the most useful and interesting in practical pharmacology. Students expressed interest in microteaching and problem-based learning, whereas seminars, demonstrations on manikin and museum studies were mentioned as good adjuvants to routine teaching. Multiple Choice Question (MCQ) practice tests and theory viva at the end of a particular system and periodical written tests were mentioned as effective evaluation methods. Students were found to have lot of interest in gathering information on recent advances in pharmacology and suggested to include new drug information along with prototype drugs in a comparative manner. There is a need of conducting few microteaching sessions and more of clinical-oriented problem-based learning with MCQ-based revisions at the end of each class in the pharmacology teaching at undergraduate level.

    Background Glucose dysregulation in pregnancy may affect maternal depressive symptoms during the prenatal and postpartum periods via both physiologic and psychological pathways. Methods During mid-pregnancy, a combination of 50-gram 1-h non-fasting glucose challenge test (GCT) and 100-gram 3-h fasting oral glucose tolerance test (OGTT) was used to determine pregnancy glycemic status among women participating in Project Viva: normal glucose tolerance (NGT), isolated hyperglycemia (IHG), impaired glucose tolerance (IGT) and gestational diabetes mellitus (GDM). Using the Edinburgh Postnatal Depression Scale (EPDS), we assessed depressive symptoms at mid-pregnancy and again at 6 months postpartum. We used logistic regression, adjusted for sociodemographic, anthropometric and lifestyle factors, to estimate the risk of elevated prenatal and postpartum depressive symptoms (EPDS ≥ 13 on 0–30 scale) in relation to GCT glucose levels and GDM status in separate models. Results 9.6% of women showed prenatal and 8.4% postpartum depressive symptoms. Women with higher GCT glucose levels were at greater odds of elevated prenatal depressive symptoms (multivariable-adjusted OR per SD increase in glucose levels (27 mg/dL): 1.25; 95%: 1.07, 1.48). Compared with NGT women, the association appeared stronger among women with IHG (OR: 1.80; 95% CI: 1.08, 3.00) than among those with GDM (OR: 1.45; 95% CI: 0.72, 2.91) or IGT (OR: 1.43; 95% CI: 0.59, 3.46). Neither glucose levels assessed from the GCT nor pregnancy glycemic status were significantly associated with elevated postpartum depressive symptoms. Conclusion Pregnancy hyperglycemia was cross-sectionally associated with higher risk of prenatal depressive symptoms, but not with postpartum depressive symptoms. PMID:26058318

    Unlike other natural hazards, earthquakes strike suddenly and without warning. Consequently, prevention is the best we can do to ensure safety. In spite of the large and medium earthquakes, some of them tsunamigenic, that affected Portugal in the past, the Portuguese society is little aware of the seismic risk and has not developed an adequate culture of prevention. This is most probably due to the long time interval between destructive earthquakes. Earthquakes can be a real danger to societies, damaging human-made structures and endangering human lives. Earthquakes can trigger additional emergencies, and individuals should also be prepared to contend with it. By planning and practicing what to do if an earthquake strikes, children and their family can learn to react correctly and automatically when the shaking begins. Risks can then be dramatically lessened if the population is educated on how to react before, during and after an earthquake. Children's knowledge is ever growing. They have a fundamental role in changing societies. By educating the children of today we are forming better adults of tomorrow. We are simultaneously passing this knowledge to their caregivers and families. Through demonstrating how fundamental it is to be conscious of those issues, not only will the children will be informed, but also their relatives will be aware of such risks. We use this approach to explain children how to assess risk in a broader sense. We teach them other preventive measures, namely those related with electricity, gas and the danger on non-potable water, essential topics on "what to do before an earthquake" but also on the daily routines. This presentation will highlight the importance of encouraging a culture of prevention. This project funded by the Portuguese "Ciência Viva" program, and is conducted by science high-school students, teachers and the parents association. Scientific support is given by the seismology research group at Instituto Dom Luíz.

    Teaching students, aged from 4 up to 18 years old, is a challenging task. It continuously implies new strategies and new subjects adapted to all of them. This is even more evident, when we have to teach natural-hazards scientific aspects and safe attitudes toward risk. We often see that most of the high-school students (16 -18 years old) are not motivated for extra-curricular activities implying science and/or behaviours changes. But, they have a very positive response when we give them some responsibility. On top of that, we also realised that young children are quite receptive to the involvement of older students in the school environment Taking this into consideration, our project use the k12 students to prepare scientific activities and subjects, based in questions, which they need to answer themselves. The students need to answer those questions and, only then, adapt and teach the right answers to the different school-levels. With this approach, we challenged the students to solve three questions: How to use a SEP seismometer at school, and its data? How to set up a shaking table? How to introduce waves and vibrations contents to all ages of students? During the project they developed many science skills, and worked in straight cooperation with teachers, the parents association and the seismology research group at Instituto Dom Luíz. As a result, it was possible to reach all school students with the help of the k-12 ones. This is an outcome of the project W-Shake, a Parents-in-Science Initiative to promote the study of seismology and related subjects. This project, supported by the Portuguese "Ciência Viva" program, results from a direct cooperation between the parents association, science school-teachers and the seismology research group at Instituto Dom Luíz.

    Urban environments were and are tremendous consumers of geologic resources, offering excellent places for Geosciences outreach activities. Since 2011, three distinct science outreach activities were planned, produced and performed in three Algarve cities - Faro (GeoStories of Faro's Downtown), Lagos (Geology at the Corner) and Tavira (From the Museum to the Convent). Urban structures - churches, monuments, buildings and urban equipments were the starting point of the geological and paleontological stories that constitute the core of these informal education visits which also combine Art History and Heritage aspects. The urban buildings were the narrative tool to these Geosciences stories being the characters the rocks and/or the fossils as well as the city itself. Beyond the natural science element, the analyzed objects have relevant esthetical, historical or symbolic dimensions, conferring this way two levels of interpretation to the stories: the geosciences level; the other, the Historical and Architectural Heritage. The nineteen visits had 350 participants - Tavira (6; 100), Faro (4; 70) e Lagos (9; 180). Promoting and contribute to the Geosciences (Geology and Paleontology) outreach was the main objective of these walks, as well as: - modify the way that the general population looks at urban buildings; - contribute to the informal education of a general public especially among the public which is interested in Architecture, History and Heritage; - integrate different areas of human knowledge - Geosciences and Architecture, History and Heritage. The visits were tested and implemented and presently constitute one of the science outreach activities of the Ciência Viva Centers in the Algarve. As a result of these visits three bilingual books (Portuguese and English) of the Geosciences walks were edited. The guides, with 120 pages each, focus on the geological and paleontological characteristics of the visited places as well as the art history framework of the

    Shorter stature is associated with greater all cause and heart disease mortality, but taller stature with increased risk of cancer mortality. Though childhood environment is important in determining height, limited data address how maternal depression affects linear growth in children. We examined the relationships between antenatal and postpartum depressive symptoms and child height and linear growth from birth to age 3 years in a U.S. sample. Subjects were 872 mother-child pairs in Project Viva, a prospective pre-birth cohort study. The study population is relatively advantaged with high levels of income and education and low risk of food insecurity. We assessed maternal depression at mid-pregnancy (mean 28 weeks' gestation) and 6 months postpartum with the Edinburgh Postnatal Depression Scale (score > = 13 on 0-30 scale indicating probable depression). Child outcomes at age 3 were height-for-age z-score (HAZ) and leg length. HAZ was also available at birth and ages 6 months, 1, 2, and 3 years. Seventy (8.0%) women experienced antenatal depression and 64 (7.3%) experienced postpartum depression. The mean (SD) height for children age 3 was 97.2 cm (4.2), with leg length of 41.6 cm (2.6). In multivariable linear regression models, exposure to postpartum depression was associated with greater HAZ (0.37 [95% confidence interval: 0.16, 0.58]) and longer leg length (0.88 cm [0.35, 1.41]). The relationship between postpartum depression and greater HAZ was evident starting at 6 months and continued to age 3. We found minimal relationships between antenatal depression and child height outcomes. Our findings do not support the hypothesis that maternal depression is associated with reduced height in children in this relatively advantaged sample in a high-income country.

    Seeds are considered to be agro-industrial residues, which can be used as source of macronutrients and/or raw material for extraction of vegetable oils, since they present great quantities of bioactive compounds. This study aimed to characterize the lipid fractions and the seeds of pumpkin (Cucurbita sp) varieties Nova Caravela, Mini Paulista, Menina Brasileira, and Moranga de Mesa aiming at using them in food. The chemical composition of the seeds was performed according to the official methods of American Oil Chemists' Society and Association of Official Analytical Chemists. Total carotenoids and phenolic compounds were determined by spectrophotometry, while the levels of tocopherols were analyzed by high efficiency liquid chromatography. It was noted that the seeds contain high amounts of macronutrients that are essential for the functioning of the human organism. As to total carotenoids, Mini Paulista and Menina Brasileira pumpkin varieties presented significant amounts, 26.80 and 26.03 μg/g, respectively. Mini Paulista and Nova Caravela pumpkin varieties showed high amounts of total phenolic compounds in the lipid fractions and in the seeds. It was also found that γ-tocopherol is the isomer that stood out in the lipid fractions and in the seeds, mainly in Menina Brasileira. Finally, the consumption of these seeds and use of lipid fractions provide the supply of large quantities of compounds that are beneficial for health and that may be potentially used in food, besides representing an alternative to better use of agro-industrial residues. Bioactive compounds, besides presenting basic nutritional functions, provide metabolic and physiological health benefits when consumed as part of the usual diet. Therefore, there is a growing interest in vegetable oils of special composition, such as the ones extracted from fruit seeds. The seeds of Cucurbita sp are shown to be promising sources of oils, and especially the Cucurbita moschata and maxima species have not yet

    Obstructive sleep apnea syndrome has multifactorial causes. Although indications for surgery are evaluated by well-known diagnostic tests in the awake state, these do not always correlate with satisfactory surgical results. To undertake a systematic review on endoscopy during sleep, as one element of the diagnosis routine, aiming to identify upper airway obstruction sites in adult patients with OSAS. By means of electronic databases, a systematic review was performed of studies using drug-induced sleep endoscopy to identify obstruction sites in patients with OSAS. Ten articles were selected that demonstrated the importance of identifying multilevel obstruction, especially in relation to retrolingual and laryngeal collapse in OSAS. DISE is an additional method to reveal obstruction sites that have not been detected in awake patients. Copyright © 2015 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial.

    In the absence of an iron chelating agent, patients with beta-thalassemia on regular transfusions present complications of transfusion-related iron overload. Without iron chelation therapy, heart disease is the major cause of death; however, hepatic and endocrine complications also occur. Currently there are three iron chelating agents available for continuous use in patients with thalassemia on regular transfusions (desferrioxamine, deferiprone, and deferasirox) providing good results in reducing cardiac, hepatic and endocrine toxicity. These practice guidelines, prepared by the Scientific Committee of Associação Brasileira de Thalassemia (ABRASTA), presents a review of the literature regarding iron overload assessment (by imaging and laboratory exams) and the role of T2* magnetic resonance imaging (MRI) to control iron overload and iron chelation therapy, with evidence-based recommendations for each clinical situation. Based on this review, the authors propose an iron chelation protocol for patients with thalassemia under regular transfusions. PMID:24478610

    Myasthenia gravis is an autoimmune disorder that is characterized by muscle weakness that fluctuates, worsening with exertion, and improving with rest. Diagnosis of myasthenia gravis is made following clinical and physical examination and is confirmed by serum immunoassays to measure autoantibody levels. Myasthenia gravis especially when associated with pregnancy is a high-risk disease, and its course is unpredictable. We described the second report about use of sugammadex after rocuronium for a caesarean delivery with myasthenia gravis, but, unlike our case that formerly was diagnosed with myasthenia gravis, the patient was extubated on postoperative successfully and we did not encounter any respiratory problems.

    This is a Social History study which aims at recuperating the professional trajectory of Glete de Alcântara in the Revista Brasileira de Enfermagem/REBEn (Brazilian Journal of Nursing), initially called Anais de Enfermagem. It is based on the concept of memory of Maurice Halbwach, and on the concept of generation of Daniel Pécaut. The study contextualizes the professional development of Glete de Alcântara in the history of the Brazilian nursing, highlighting the creation of the Nursing School of the University of São Paulo (EERP/USP) in Ribeirão Preto. The sources for the study were documents obtained in the Centro de Memória da Escola de Enfermagem (Memory Center of the School of Nursing) of Ribeirão Preto and in ABEN (Brazilian Association of Nursing) in Brasília. Data obtained in this association were mainly collected from its record books the journals.

    Nasal packing is routinely used in septal surgery to prevent postoperative bleeding. To demonstrate the possibility of transeptal suture as a safe and effective way to avoid nasal packing and to improve efficiency. This is a prospective, descriptive, inferential cost study comprising 92 patients. Two randomized groups of patients were analyzed, one with nasal packing and the other with transeptal suture. In the group of transeptal suture no patient experienced postoperative bleeding, and a statistically significant reduction of pain and headache was demonstrated. At the same time, we improved efficiency by saving on material costs. Transeptal suture is an effective and safe alternative to classic nasal packing in septal surgery. Moreover, it improves the efficiency of the intervention by saving costs. Copyright © 2015 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial. Published by Elsevier Editora Ltda.

  5. Biothics in Brazil.

    PubMed

    Diniz, Debora; Guilhem, Dirce Bellezi; Garrafa, Volnei

    1999-07-01

    In this article the authors briefly sketch the nature of Brazilian bioethics. Bioethics emerged in Brazil later than in other Western countries and the 1990's were the most important period for the spread of the discipline in the country. It is in this period that some structural elements of bioethics were established, such as research groups, regulation of Local Research Ethics Committees (Comitês Locais de Etica em Pesquisa -- CEP), the creation of the National Commission of Ethics in Research with Human Beings (Comissão Nacional de Etica em Pesquisa com Seres Humanos -- CONEP) and the Brazilian Bioethics Society (Sociedade Brasileira de Bioética -- SBB). With regard to theoretical work, Brazilian bioethics is clearly an importer of theories from countries central to the studies of bioethics, or, in other words, countries where biothics first emerged and was established. The most commonly used theory among Brazilian researchers is principalism.

    To evaluate whether there is a preference for foreign periodicals over Brazilian one. We evaluated all references of articles published in the years 2011 and 2007 in the journals Acta Cirúrgica Brasileira, Arquivos Brasileiros de Cirurgia Digestiva and the Journal of the Brazilian College of Surgeons, verifying the quantity of papers from Brazilian and foreign publications. We analyzed a total of 7,343 references arranged in 348 articles in those three journals; of these, 856 (11.65%) were from Brazilian journals. There was no difference between the three magazines, nor between the two periods. One hundred and eleven (31.9%) articles did not cite any Brazilian journal article and 36 (10.34%) cited Brazilian articles more than foreign ones. There is need for the Brazilian researcher to appreciate more the Brazilian journals, increasing citation from Brazil, without a scientific xenophobia.

    This work performed a phenotypic and genotypic characterization of 79 clinical isolates of Enterobacteriaceae and Pseudomonadaceae collected in hospitals of Southern Ecuadorin 2013. Our results showed a high incidence of β-lactamases and ESBLs with blaTEM and blaCTX-M as the prevalent genes, respectively. By direct sequencing of PCR amplicons, the different β-lactamases and variants of the genes were also distinguished. Our results revealed a predominance of TEM-1 β-lactamase and the presence of different CTX-M variants with a prevalence of CTX-M-15. Two infrequent CTX-M variants in South America were also identified. To the best of our knowledge, this is one of the first studies describing the genetic characteristics of β-lactamases in Ecuador.

    This communication reports the second known case of oral phaeohyphomycosis in a patient with squamocellular carcinoma of the lip. The patient, an 82-year-old black woman, a former smoker (for more than 30 years), suffering from an ulcerous vegetative lesion in the middle third of the lower lip for approximately 12 months. The result of the histopathological analysis indicated carcinoma, with well-differentiated keratinized squamous cells and the presence of septate mycelial filaments. In the direct mycological examination, thick and dematiaceous septate mycelial filaments were observed. After the resection surgery, the patient did not need to use an antifungal drug to treat the phaeohyphomycosis, and no follow-up radiotherapy was needed to treat the squamocellular carcinoma. We stress that the presence of the squamocellular lesion of the lip was a possible contributing factor to the infection. Copyright © 2016 Sociedade Brasileira de Microbiologia.

    Congenital unilateral absence of a pulmonary artery (UAPA) is a rare anomaly. Although there are several reports regarding pregnancy in patients with unilateral absence of a pulmonary artery, there are no case reports describing anesthesia for Cesarean section in a patient with unilateral absence of a pulmonary artery. We present a patient with unilateral absence of a pulmonary artery who underwent Cesarean sections twice at the ages of 24 and 26 years under spinal anesthesia for surgery and epidural analgesia for postoperative pain relief. Both times, spinal anesthesia and epidural analgesia enabled successful anesthesia management without the development of either pulmonary hypertension or right heart failure. Spinal anesthesia combined with epidural analgesia is a useful anesthetic method for a Cesarean section in patients with unilateral absence of a pulmonary artery.

    Ectodermal dysplasias are rare conditions with a triad of hypotrichosis, anodontia and anhidrosis. In literature review there have been only a few reports of anesthetic management of patients with ectodermal dysplasias. Hyperthermia is a very serious risk which may occur due to the defect of sweat glands. The present case involves a 10-year-old child with ectodermal dysplasia who presented with an acute abdomen and was considered for an emergency surgery. Our aim was to demonstrate the successful management of this case using a combination of general and epidural anesthesia. It is important for anesthesiologist to have information about this syndrome in case of emergency operations, since it can prevent serious complications and even save lives.

    Proliferative verrucous leukoplakia is a multifocal and progressive lesion of the oral mucosa, with unknown etiology, and commonly resistant to all therapy attempts with frequent recurrences. It is characterized by a high rate of oral squamous cell carcinoma and verrucou carcinoma transformations. To analyze the studies about Proliferative verrucous leukoplakia and develop a concise update. A Pubmed search identifying studies (laboratory research, case series and reviews of literature) that examined patients with Proliferative verrucous leukoplakia was realized. There are not enough studies about Proliferative verrucous leukoplakia in the literature. The few found studies not present a consensus about its etiology and diagnosis criteria. Although several treatment strategies have been proposed, most of them still show a high recurrence rate. More research about Proliferative verrucous leukoplakia is necessary to understand and treat this disease. Copyright © 2017 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial.

    This paper traces the influence of F. W. Taylor and H. Fayol in the scientific output of brazilian nursing from 1930 to 1980. The scientific output of brazilian nursing is reviewed, looking for work based upon the Scientific and Classical Schools of Administration. The author executes a bibliographic survey based upon two periodicals: Revista Brasileira de Enfermagem and Revista Paulista de Hospitais. A total of 68 articles were selected and studied. Findings have shown that Taylor/Fayol had and still have an important influence on the theoretic foundation of nursing output. The central theme of the texts centers upon "Studies on the Organization of Hospital Nursing Services", and "Time and Motion Studies concerning Nursing Techniques and Activities:. The central preoccupation in these texts refers to productivity and rationality of work, regardless of the fact that the organization of health and nursing work is a human task, referring to the satisfaction of health needs.

    This literature review deals with curricular supervisioned traineeship in the nursing undergraduate program, whose objectives were to understand how the program is currently structured and to identify today's challenges, by tracing back its history and understanding the laws governing the program. Issues of Revista Brasileira de Enfermagem published between 1954 and 2006 were used as a main source. The study revealed that this academic activity has gone through several transformations since it was first structured in 1972, at a time when nursing was carried out from a biologicist and hospital-centered perspective. After 1994, it sought to have a structure based on the integrality and articulation between theory and practice, and teaching and service, with a view to the construction of the Brazilian public health system - SUS; a process that was enhanced in 2001 upon the implementation of the Brazilian Education Guidelines.

    Ralstonia solanacearum is a heterogeneous species complex causing bacterial wilts in more than 450 plant species distributed in 54 families. The complexity of the genome and the wide diversity existing within the species has led to the concept of R. solanacearum species complex (RsSC). Here we report the genome sequence of the four strains (RS2, RS25, RS48 and RS75) belonging to three of the four phylotypes of R. solanacearum that cause potato bacterial wilt in India. The genome sequence data would be a valuable resource for the evolutionary, epidemiological studies and quarantine of this phytopathogen. Copyright © 2016 Sociedade Brasileira de Microbiologia.

    We report the first description of a rare catalase-negative strain of Staphylococcus aureus in Chile. This new variant was isolated from blood and synovial tissue samples of a pediatric patient. Sequencing analysis revealed that this catalase-negative strain is related to ST10 strain, which has earlier been described in relation to S. aureus carriers. Interestingly, sequence analysis of the catalase gene katA revealed presence of a novel nonsense mutation that causes premature translational truncation of the C-terminus of the enzyme leading to a loss of 222 amino acids. Our study suggests that loss of catalase activity in this rare catalase-negative Chilean strain is due to this novel nonsense mutation in the katA gene, which truncates the enzyme to just 283 amino acids.

    Tracheal stenosis is a rare but a life-threatening condition and anesthesia of a patient with tracheal stenosis is challenging for anesthesiologists. Maintaining stable hemodynamics and ventilation parameters are important issues in neuroanesthesia. Any increase in airway peak pressure and ETCO2 will result in increase in intracranial pressure which must be avoided during craniotomies. Tracheal stenosis could be a reason for increased airway pressure. We described a patient undergoing craniotomy with tracheal stenosis. Detailed preparation for intubation, to stabilize airway dynamics and to make the right decision for the surgery were important points. To maintain a good balance between cerebral dynamics and airway dynamics were the pearls of this case. Copyright © 2014 Sociedade Brasileira de Anestesiologia. Publicado por Elsevier Editora Ltda.

    Percutaneous vertebroplasty is a relatively safe, simple and commonly performed interventional procedure for the management of vertebral compression fractures. However, serious complications are rarely reported in the procedure. Those are pulmonary embolism, severe infection, paraplegia and an occurrence of a new fracture in an adjacent vertebra after vertebroplasty. Acute complications are generally associated with the procedure. We present the case of neuraxial anesthesia, developed after local anesthesia with 8mL of 2% prilocaine, in a 68-year-old woman who underwent percutaneous vertebroplasty after an osteoporotic collapsed fracture in the L1 vertebra due to trauma. To our knowledge, this is the first case in the literature. Copyright © 2014 Sociedade Brasileira de Anestesiologia. Publicado por Elsevier Editora Ltda. All rights reserved.

    Thoracic paravertebral block can provide analgesia for unilateral chest surgery and is associated with a low complication rate. Horner syndrome also referred to as oculosympathetic paresis, is a classic neurologic constellation of ipsilateral blepharoptosis, pupillary miosis, and facial anhidrosis resulting from disruption of the sympathetic pathway supplying the head, eye, and neck. We present a patient with an ipsilateral transient Horner syndrome after ultrasound guided single shot of 15mL 0.25% levobupivacaine for thoracic paravertebral block at T5-6 level. It should be kept in mind that even a successful ultrasound guided single shot thoracic paravertebral block can be complicated with Horner syndrome due to unpredictable distribution of the local anesthetic.

    The current increment of invasive fungal infections and the availability of new broad-spectrum antifungal agents has increased the use of these agents by non-expert practitioners, without an impact on mortality. To improve efficacy while minimizing prescription errors and to reduce the high monetary cost to the health systems, the principles of pharmacokinetics (PK) and pharmacodynamics (PD) are necessary. A systematic review of the PD of antifungals agents was performed aiming at the practicing physician without expertise in this field. The initial section of this review focuses on the general concepts of antimicrobial PD. In vitro studies, fungal susceptibility and antifungal serum concentrations are related with different doses and dosing schedules, determining the PD indices and the magnitude required to obtain a specific outcome. Herein the PD of the most used antifungal drug classes in Latin America (polyenes, azoles, and echinocandins) is discussed. Copyright © 2016 Sociedade Brasileira de Infectologia.

    to identify how the notion of vulnerability is used in national and international scientific publications that address the problem of tuberculosis. an integrative review of literature published in the databases of the Biblioteca Virtual em Saúde, the United States National Library of Medicine and the Biblioteca Digital Brasileira de Teses e Dissertações, considering the descriptors Tuberculosis and Vulnerability in Portuguese and English. we selected fifty-eight studies published between 1992 and February 2014, which resulted in three categories of analysis. CONCLUSION the link between tuberculosis and the notion of vulnerability has not been sufficiently consolidated in national and international literature. This creates an obstacle for the achievement of the epistemological transformations and pragmatic measures that are required to obtain better results from interventions in the field.

    We have revisited the fragment-asperity interaction model recently introduced by Sotolongo-Costa and Posadas [Phy. Rev. Lett. 92, 048501 (2004)] by considering a different definition for mean values in the context of Tsallis nonextensive statistics and introducing a scale between the earthquake energy and the size of fragment epsilon proportional to r3. The energy-distribution function (EDF) deduced in our approach is considerably different from the one obtained in the above reference. We have also tested the viability of this EDF with data from two different catalogs (in three different areas), namely, the NEIC and the Bulletin Seismic of the Revista Brasileira de Geofísica. Although both approaches provide very similar values for the nonextensive parameter , other physical quantities, e.g., energy density, differ considerably by several orders of magnitude.

The objective was to identify emergent themes on qualitative researches published on a nursing periodic; correlate theses themes with the knowledge production in nursing and reflect about the social role of these qualitative researches analyzed. After analysis, 173 qualitative studies were identified, and three categories arose: nursing training, areas of practice, nursing care basis/ principles/ conceptions, and professional issues. In the relationship among the categories, the patterns of knowledge and the social role highlight the social-political knowledge, reflecting the profession maturation regarding intrinsic social issues, part of it social body; and extrinsic, the demands from society.

    A historical-sociological study aimed at analyzing and describing the visibility of the performance of a Brazilian Army nurse engaged in the Força Expedicionária Brasileira--FEB (Brazilian Expeditionary Force) during the Second World War. Primary source: a photograph taken at the time, along with the oral testimony of nineteen agents. This mode of gathering data resulted in the creation of a new method of research, which we named Oral-Photographic Analysis. The photo was picked in the Brazilian Army's iconographic collection, located at the Comando Militar do Leste (Eastern Military Command), in Rio de Janeiro. Secondary sources: literature on the sociohistorical context of the period. We used Pierre Bourdieu's concepts of habitus, power and cultural capital. The results showed that, in order to face such challenge and care for the wounded, the volunteer nurses had to acquire new habitus through mandatory training given by the military.

    The extensive use of central venous catheters (CVC) in a hospital environment leads to increased iatrogenic complications, as more catheters are used enclosed and its maintenance is prolonged. Several complications are known to be related to central venous catheter, of which the uncommon cardiac tamponade (CT), hardly recognized and associated with high mortality. We present a clinical case, with favorable outcome, of a patient who developed a CT 17 days after CVC placement, and try to reflect on the measures that can be taken to reduce its incidence, as well as the therapeutic approaches to practice in the presence of a suspected CT.

    We have revisited the fragment-asperity interaction model recently introduced by Sotolongo-Costa and Posadas [Phy. Rev. Lett. 92, 048501 (2004)] by considering a different definition for mean values in the context of Tsallis nonextensive statistics and introducing a scale between the earthquake energy and the size of fragment γ∝r3 . The energy-distribution function (EDF) deduced in our approach is considerably different from the one obtained in the above reference. We have also tested the viability of this EDF with data from two different catalogs (in three different areas), namely, the NEIC and the Bulletin Seismic of the Revista Brasileira de Geofísica. Although both approaches provide very similar values for the nonextensive parameter q , other physical quantities, e.g., energy density, differ considerably by several orders of magnitude.

    Adequate analgesia after sternotomy reduces postoperative adverse events. There are various methods of treating pain after heart surgery, such as infiltration with a local anesthetic, nerve block, opioids, non-steroidal anti-inflammatory drugs, alpha-adrenergic agents, intrathecal and epidural techniques, and multimodal analgesia. A review of the epidemiology, pathophysiology, prevention and treatment of pain after sternotomy. We also discuss the various analgesic therapeutic modalities, emphasizing advantages and disadvantages of each technique. Heart surgery is performed mainly via medium sternotomy, which results in significant postoperative pain and a non-negligible incidence of chronic pain. Effective pain control improves patient satisfaction and clinical outcomes. There is no clearly superior technique. It is believed that a combined multimodal analgesic regimen (using different techniques) is the best approach for treating postoperative pain, maximizing analgesia and reducing side effects.

  18. [Post operative visual loss after cervical laminectomy in prone position].

    Chandra, Kumar Naren; Kundan, Meghraj

    Postoperative visual loss is a rare and devastating complication. The estimated incidence is 0.01-1% after non ocular surgery. It has been reported after spine, cardiac and head and neck surgeries. We report a patient who was operated for cervical laminectomy in prone position and complained of loss of vision in one eye postoperatively. He was thoroughly investigated after visual loss. The case was diagnosed as central retinal artery occlusion (CRAO) of the left eye. Here we consider the potential etiological factors causing this unilateral loss of vision and try to suggest strategies to reduce the incidence of the complication in spinal surgery.

    This study proposed a version of the Children's Sleep Habits Questionnaire for infants under 12 months (CSHQ-I). The sample was comprised of 299 infants, aged between 2 weeks and 12 months. Exploratory factor analysis revealed four subscales: Bedtime Resistance, Sleep Anxiety, Positive Sleep Habits, and Daytime Sleepiness. The CSHQ-I total scale presented good test-retest reliability and internal consistency. The CSHQ-I also showed good concurrent validity, with significant associations found between the CSHQ-I total scale and subscales and a measure of infant sleep-wake behaviors. The present study suggested the CSHQ-I as a reliable instrument to assess sleep problems in infants during the first year of life. Copyright © 2017 Sociedade Brasileira de Pediatria.

    The anesthetic management of patients with large mediastinal masses can be complicated due to the pressure effects of the mass on the airway or major vessels. We present the successful anesthetic management of a 64-year-old female with a large mediastinal mass that encroached on the great vessels and compressed the trachea. A tracheal stent was placed to relieve the tracheal compression under general anesthesia. Spontaneous ventilation was maintained during the perioperative period with the use of a classic laryngeal mask airway. We discuss the utility of laryngeal mask airway for anesthetic management of tracheal stenting in patients with mediastinal masses. Copyright © 2014 Sociedade Brasileira de Anestesiologia.
