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.

Hypovitaminosis D has been associated with age-related physical decline and an increased risk for falls. The objective of this study is to test whether supplementation with 4000IU of vitamin D(3) (vitD(3)) for 9 months will improve, or slow down the decline of the ability to perform physical tests which have been associated with the preservation of independence in sedentary older men. We describe the study design and the baseline characteristics of the 314 men screened in the VIVA-VA Study (Vitamin D In Vulnerable Adults in the VA), a 2-year, single-site, double-blind, placebo-controlled, randomized clinical trial that enrolled sedentary male veterans ages 65 to 95. The main inclusion criteria are 25-OH vitamin D (25-OHD) levels between 10 and 30 ng/ml, and a Short Performance Physical Battery (SPPB) score ≤ 9. The primary outcome of the study is the SPPB. Subjects were recruited from the Miami Veterans Medical Center clinics. The study recruited 314 male veterans of multiethnic backgrounds. The baseline characteristics observed from the 314 men screened in the VIVA-VA Study are consistent with what is expected in a cohort of elderly sedentary men: low physical performance scores, and low 25OHD levels despite living in South Florida. The results of this study that uses a high dose of vitamin D in a cohort of sedentary older men could provide an evidence-based indication for vitamin D supplementation to improve physical performance in this population.

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.

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.

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.

Background 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. Methods 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. Results 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 [−5.2 ng/mL (95% CI: −8.6, −1.7)], with more pronounced associations in girls [−10.7 ng/mL (95% CI: −18.5, −2.9) vs. −4.0 ng/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. Conclusions 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. PMID:28641780

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.

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.

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.

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.

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.

Inflammation during pregnancy has been linked to adverse maternal and infant outcomes. There is limited information available on the contribution of maternal diet to systemic inflammation and pregnancy health. The objective of this study was to examine associations of maternal prenatal dietary inflammatory index (DII), a composite measure of the inflammatory potential of diet, with markers of maternal systemic inflammation and pregnancy outcomes. We studied 1808 mother-child pairs from Project Viva, a pre-birth cohort study in Massachusetts. We calculated the DII from first- and second-trimester food-frequency questionnaires by standardizing the dietary intakes of participants to global means, which were multiplied by the inflammatory effect score and summed. We examined associations of DII with maternal plasma C-reactive protein and white blood cell count in the second trimester and the following perinatal outcomes: gestational diabetes, preeclampsia, length of gestation, fetal growth, mode of delivery, and duration of breastfeeding. We used multivariable linear and logistic regression models to analyze the strength of these associations. Maternal age was (mean ± SD) 32.2 ± 5.0 y, prepregnancy body mass index (BMI; in kg/m(2)) was 24.9 ± 5.2, and DII was -2.56 ± 1.42 units with a range of -5.4 to 3.7. DII was positively correlated with prepregnancy BMI (Pearson'sr= 0.13,P< 0.0001). Higher DII scores, reflecting more proinflammatory dietary potential, were associated with higher second-trimester plasma CRP (β: 0.08 mg/L per 1-unit increase in maternal DII; 95% CI: 0.02, 0.14) and lower birth weight for gestational agezscore in infants born to obese mothers (β: -0.10zscore per 1-unit increase in maternal DII; 95% CI: -0.18, -0.02). Higher DII scores were associated with lower odds of breastfeeding for at least 1 mo (OR = 0.85; 95% CI: 0.74, 0.98). A proinflammatory diet during pregnancy is associated with maternal systemic inflammation and may be associated

Background: 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. Objective: 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. Design: We conducted a genomewide association study with 1.1 million genetic markers in 815 children. Results: We found serum uric acid to be significantly heritable [h2 ± 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). Conclusions: 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. PMID:25833971

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.

[Work, momentum and fatigue in the work of Daniel Bernoulli: toward the optimization of biological fact].

Fonteneau, Yannick; Viard, Jérôme

The concept of mechanical work is inherited from the concepts of potentia absoluta and men's work, both implemented in the section IX of Daniel Bernoulli's Hydrodynamica in 1738. Nonetheless, Bernoulli did not confuse these two entities: he defined a link from gender to species between the former, which is general, and the latter, which is organic. In addition, Bernoulli clearly distinguished between vis viva and potentia absoluta (or work). Their reciprocal conversions are rarely mentioned explicitly in this book, except once, in the section X of his work, from vis viva to work, and subordinated to the mediation of a machine, in a driving forces substitution problem. His attitude evolved significantly in a text in 1753, in which work and vis viva were unambiguously connected, while the concept of potentia absoluta was reduced to that of human work, and the expression itself was abandoned. It was then accepted that work can be converted into vis viva, but the opposite is true in only one case, the intra-organic one. It is the concept of fatigue, seen as an expenditure of animal spirits themselves conceived of as little tensed springs releasing vis viva, that allowed the conversion, never quantified and listed simply as a model, from vis viva to work. Thus, work may have ultimately appeared as a transitional state between two kinds of vis viva, of which the first is non-quantifiable. At the same time, the natural elements were discredited from any hint of profitable production. Only men and animals were able to work in the strict sense of the word. Nature, left to itself, does not work, according to Bernoulli. In spite of his wish to bring together rational mechanics and practical mechanics, one perceived in the work of Bernoulli the subsistence of a rarely crossed disjunction between practical and theoretical fields.

Background The immunosuppressant drugs (ISDs), tacrolimus and cyclosporine, are vital for solid organ transplant patients to prevent rejection. However, toxicity is a concern, and absorption is highly variable across patients; therefore, ISD levels need to be precisely monitored. In the Asia-Pacific (APAC) region, tacrolimus and cyclosporine concentrations are typically measured using immunoassays. The objective of this study was to assess the analytical performance of Roche Elecsystacrolimus and cyclosporinee electrochemiluminescence immunoassays (ECLIAs). Methods This evaluation was performed in seven centers across China, South Korea, and Malaysia. Imprecision (repeatability and reproducibility), assay accuracy, and lot-to-lot reagent variability were tested. The Elecsys ECLIAs were compared with commercially available immunoassays (Architect, Dimension, and Viva-E systems) using whole blood samples from patients with various transplant types (kidney, liver, heart, and bone marrow). Results Coefficients of variation for repeatability and reproducibility were ≤5.4% and ≤12.4%, respectively, for the tacrolimus ECLIA, and ≤5.1% and ≤7.3%, respectively, for the cyclosporine ECLIA. Method comparisons of the tacrolimus ECLIA with Architect, Dimension, and Viva-E systems yielded slope values of 1.01, 1.14, and 0.897, respectively. The cyclosporine ECLIA showed even closer agreements with the Architect, Dimension, and Viva-E systems (slope values of 1.04, 1.04, and 1.09, respectively). No major differences were observed among the different transplant types. Conclusions The tacrolimus and cyclosporine ECLIAs demonstrated excellent precision and close agreement with other immunoassays tested. These results show that both assays are suitable for ISD monitoring in an APAC population across a range of different transplant types. PMID:29214751

Percutaneous dilatational tracheostomy (PDT) in critically ill patients often involves bronchoscopic optical guidance. However, this procedure is not without disadvantages. Therefore, we aimed to study a recently introduced endotracheal tube-mounted camera (VivaSight TM -SL tube [VST]; ETView, Misgav, Israel) for guiding PDT. This was a randomized controlled trial involving 46 critically ill patients who received PDT using optical guidance with a VST or with bronchoscopy. The primary outcome measure was visualization of the tracheal structures (i.e., identification and monitoring of the thyroid, cricoid, and tracheal cartilage and the posterior wall) rated on 4-point Likert scales. Secondary measures were the quality of ventilation (before puncture and during the tracheostomy procedure rated on 4-point Likert scales) and blood gases sampled at standardized time points. The mean ratings for visualization (lower values better; values given for per-protocol analysis) were 5.4 (95% CI 4.5-6.3) for the VST group and 4.0 (95% CI 4.0-4.0) for the bronchoscopy group (p < 0.001). Mean ventilation ratings were 2.5 (95% CI 2.1-2.9) for VST and 5.0 (95% CI 4.4-5.7) for bronchoscopy (p < 0.001). Arterial carbon dioxide increased to 5.9 (95% CI 5.4-6.5) kPa in the VST group vs. 8.3 (95% CI 7.2-9.5) kPa in the bronchoscopy group (p < 0.001), and pH decreased to 7.40 (95% CI 7.36-7.43) in the VST group vs. 7.26 (95% CI 7.22-7.30) in the bronchoscopy group (p < 0.001), at the end of the intervention. Visualization of PDT with the VST is not noninferior to guidance by bronchoscopy. Ventilation is superior with less hypercarbia with the VST. Because visualization is not a prerequisite for PDT, patients requiring stable ventilation with normocarbia may benefit from PDT with the VST. ClinicalTrials.gov, NCT02861001 .

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 changesmore » 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.« less

Early-life exposure to lead is associated with deficits in neurodevelopment and with hematopoietic system toxicity. DNA methylation may be one of the underlying mechanisms for the adverse effects of prenatal lead on the offspring, but epigenome-wide methylation data for low levels of prenatal lead exposure are lacking. We investigated the association between prenatal maternal lead exposure and epigenome-wide DNA methylation in umbilical cord blood nucleated cells in Project Viva, a prospective U.S.-based prebirth cohort with relatively low levels of lead exposure. Among 268 mother-infant pairs, we measured lead concentrations in red blood cells (RBC) from prenatal maternal blood samples, and using HumanMethylation450 Bead Chips, we measured genome-wide methylation levels at 482,397 CpG loci in umbilical cord blood and retained 394,460 loci after quality control. After adjustment for batch effects, cell types, and covariates, we used robust linear regression models to examine associations of prenatal lead exposure with DNA methylation in cord blood at epigenome-wide significance level [false discovery rate (FDR)<0.05]. The mean [standard deviation (SD)] maternal RBC lead level was 1.22 (0.63) μg/dL. CpG cg10773601 showed an epigenome-wide significant negative association with prenatal lead exposure (-1.4% per doubling increase in lead exposure; p=2.3×10-7) and was annotated to C-Type Lectin Domain Family 11, Member A ( CLEC11A ), which functions as a growth factor for primitive hematopoietic progenitor cells. In sex-specific analyses, we identified more CpGs with FDR<0.05 among female infants (n=38) than among male infants (n=2). One CpG (cg24637308), which showed a strong negative association with prenatal lead exposure among female infants (-4.3% per doubling increase in lead exposure; p=1.1×10-06), was annotated to Dynein Heavy Chain Domain 1 gene ( DNHD1 ) which is highly expressed in human brain.

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.

ABSTRACT The dynamics and significance of aerosol transmission of respiratory viruses are still controversial, for the major reasons that virus aerosols are inefficiently collected by commonly used air samplers and that the collected viruses are inactivated by the collection method. Without knowledge of virus viability, infection risk analyses lack accuracy. This pilot study was performed to (i) determine whether infectious (viable) respiratory viruses in aerosols could be collected from air in a real world environment by the viable virus aerosol sampler (VIVAS), (ii) compare and contrast the efficacy of the standard bioaerosol sampler, the BioSampler, with that of the VIVAS for the collection of airborne viruses in a real world environment, and (iii) gain insights for the use of the VIVAS for respiratory virus sampling. The VIVAS operates via a water vapor condensation process to enlarge aerosolized virus particles to facilitate their capture. A variety of viable human respiratory viruses, including influenza A H1N1 and H3N2 viruses and influenza B viruses, were collected by the VIVAS located at least 2 m from seated patients, during a late-onset 2016 influenza virus outbreak. Whereas the BioSampler when operated following our optimized parameters also collected virus aerosols, it was nevertheless overall less successful based on a lower frequency of virus isolation in most cases. This side-by-side comparison highlights some limitations of past studies based on impingement-based sampling, which may have generated false-negative results due to either poor collection efficiency and/or virus inactivation due to the collection process. IMPORTANCE The significance of virus aerosols in the natural transmission of respiratory diseases has been a contentious issue, primarily because it is difficult to collect or sample virus aerosols using currently available air sampling devices.

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.

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.

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.

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.

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.

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 messages in video tracking paves the way for user interaction, correction and preparation of situation awareness reports. PMID:25340453

To assess the association between self-reported racial discrimination and prenatal depressive symptoms among black women. 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). 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. 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. Copyright © 2012 Elsevier Inc.

The objective of this in vitro study was to evaluate the kinetics of hydrogen peroxide (HP) release from five different bleaching products: VivaStyle® 10% fitted tray gel, VivaStyle® 30% in-office bleaching gel, VivaStyle® Paint-On Plus paint-on bleaching varnish, Opalescence PF® 10% carbamide peroxide gel and Trèswhite Supreme™ 10% HP gel. Each product was firstly titrated for its HP content by a described method. HP release kinetics was assessed by a modified spectrophotometric technique. One sample t test was performed to test for differences between the manufacturers' claimed HP concentrations and the titrated HP content in the whitening products. Analysis of variance plus Tamhane's post hoc tests and Pearson correlation analysis were used as appropriate. Values of P < 0.05 were taken as significant. Titrated HP revealed an increased content when compared to the manufacturer's specifications for all the products tested (P < 0.05), although only products from one manufacturer produced significantly higher results. All products presented a significant (P < 0.05) and sustained release of HP. However, the product with paint-on cellulose-based matrix resulted in significantly (P < 0.05) faster kinetics when compared to other products tested. These results are consistent with manufacturers' reduced recommended application times. The results of this study suggest that modifying the matrix composition may be a viable alternative to HP concentration increase, since this may result in faster release kinetics without exposure to high HP concentrations.

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 Pendulum: From Constrained Fall to the Concept of Potential

NASA Astrophysics Data System (ADS)

2006-08-01

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.

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 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.

The present work assesses the production rate of cell phone e-waste in Kuwait by comparing the number of clients in three telecommunication service providers like Zain, Ooredoo, and Viva in the state of Kuwait over a period of 7 years from 2008 to 2015. An online survey was conducted to evaluate the growth in the number of clients in three cell phone companies, and the data analysis was carried out using statistical package for the social sciences (SPSS) software. The prediction of the growth percentage of the number of clients in each telecommunication company was analyzed using analysis of variance (ANOVA) test and followed by the regression model. The study shows that there is an increase in the number of clients in all three companies (Zain, Ooredoo, and Viva) between year 2008 and 2015, and it was estimated that approximately 7.9 million cell phone users would be achieved in the first quarter of 2015. Based on this predicted number of cell phone users, the production of e-waste would be 3 kt per year with an average growth of 12.7%.

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.

To describe emergency care for external causes in childhood, age group 0-9 years, in Brazilian capitals, collected from the Violence and Accident Surveillance System (VIVA) Survey in 2014. To review data from the VIVA survey conducted in public emergency services in 24 Brazilian capitals. Variables analyzed were gender, age group (0-1 years, 2-5 years and 6-9 years), race/skin color, type of events and injuries, aggressors and other. Eight thousand five hundred eighty-eight children received care, of which 8,164 (95%) were victims of accidents and 424 (5%) of violence. Boys suffered more accidents, most events occurred at home (65%) and discharge was the most frequent outcome. Falls were the most frequent accidents, followed by other accidents, road injury and burns. Neglect prevailed among the types of violence, followed by physical violence. The perpetrator was a child's relative in 72% of the cases, and women were the most frequent aggressors for children under 1 year, and men for children aged 6 to 9 years. Childhood accidents occurred mainly at home, and falls were the most frequent events. Family members and acquaintances perpetrated violence against children. Data point to the implementation of public prevention and child protection policies.

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.

Abstract Background: 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. Methods: 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. Results: 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. Conclusions: In normal airways and situations with continuous chest compressions, the success rate for intubation of cadavers and the time to ventilation were

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.

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.

Percutaneous dilatational tracheostomy (PDT) in critically ill patients is often led by optical guidance with a bronchoscope. This is not without its disadvantages. Therefore, we aimed to study the feasibility of a recently introduced endotracheal tube-mounted camera (VivaSight™-SL, ET View, Misgav, Israel) in the guidance of PDT. We studied 10 critically ill patients who received PDT with a VivaSight-SL tube that was inserted prior to tracheostomy for optical guidance. Visualization of the tracheal structures (i.e., identification and monitoring of the thyroid, cricoid, and tracheal cartilage and the posterior wall) and the quality of ventilation (before puncture and during the tracheostomy) were rated on four-point Likert scales. Respiratory variables were recorded, and blood gases were sampled before the interventions, before the puncture and before the insertion of the tracheal cannula. Visualization of the tracheal landmarks was rated as 'very good' or 'good' in all but one case. Monitoring during the puncture and dilatation was also rated as 'very good' or 'good' in all but one. In the cases that were rated 'difficult', the visualization and monitoring of the posterior wall of the trachea were the main concerns. No changes in the respiratory variables or blood gases occurred between the puncture and the insertion of the tracheal cannula. Percutaneous dilatational tracheostomy with optical guidance from a tube-mounted camera is feasible. Further studies comparing the camera tube with bronchoscopy as the standard approach should be performed. © 2017 The Acta Anaesthesiologica Scandinavica Foundation.

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

PubMed Central

Greenwood, John; Amjadi, Mahyar; Dearman, Bronwyn; Mackie, Ian

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.

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.

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.

VIVA (VLA Imaging of Virgo in Atomic gas): H I Stripping in Virgo Galaxies

NASA Astrophysics Data System (ADS)

Chung, A.; van Gorkom, J. H.; Crowl, H.; Kenney, J. D. P.; Vollmer, B.

2008-08-01

We present results of a new Very Large Array survey of 53 Virgo galaxies (48 spirals and 5 dwarf/irregular systems). The goal is to study how the H I gas properties are affected by the cluster environment. The survey covers galaxies in a wide range of densities from the center of the cluster to more than 3 Mpc from M 87. The gas is imaged down to a column-density sensitivity of a few times 1019cm-2. We find examples of gas stripping at all stages. Within ˜0.5 Mpc from M 87, most galaxies are severely H I stripped. The H I disks are truncated to well within the optical disks. While the H I looks asymmetric, the outer stellar disks look undisturbed. The fact that only the gas and not the stars has been stripped suggests that those galaxies have been affected by the hot and dense cluster gas. Interestingly we also find a few truncated disks at large projected distances from the center. Although some of these may have been stripped while crossing the cluster core, a detailed population-synthesis study of the outer disk of one of these shows that star formation was terminated recently. The time since stripping is too short for the galaxy to have traveled from the core to its current location. So at least one galaxy has lost its gas from the outer disk by another mechanism than ram-pressure stripping in the dense cluster core. At intermediate- to low-density regions (>0.6 Mpc) we find H I tails with various lengths. We find seven galaxies with long one-sided H I tails pointing away from M 87. The galaxies are at 0.6-1 Mpc from M 87. Since these galaxies are only mildly H I deficient and the tails point away from M 87, these galaxies are probably falling into the cluster for the first time on highly radial orbits. For all but two of the galaxies the estimated ram pressure at their location in the cluster would be sufficient to pull out the H I in the very outer disks. One galaxy also looks optically disturbed and a simulation suggests that a combination of ram pressure plus a tidal interaction has pulled out the tail. In the outskirts of the cluster we find several examples of tidally interacting galaxies. We possibly see evidence for some accretion of gas as well. Lastly, the merging of subclusters with Virgo can cause bulk motions of the ICM. We see one example of a galaxy far out that appears to be ram-pressure stripped by a dynamic ICM. In summary, our results show that galaxies are already affected in the low-density outer regions of the cluster through ram-pressure stripping and tidal interactions, or a combination of both.

Writing a Bachelor thesis is the last step in obtaining a university degree. The thesis may be job- or research-orientated, but it must demonstrate certain degree-level competences. Rubrics are a useful way of unifying the assessment criteria. To design a system of rubrics for assessing the competences associated with the Bachelor thesis of a nursing degree, to examine the system's reliability and validity and to analyse results in relation to the final thesis mark. Cross-sectional and psychometric study conducted between 2012 and 2014. Nursing degree at a Spanish university. Twelve tutors who designed the system of rubrics. Students (n = 76) who wrote their Bachelor thesis during the 2013-2014 academic year. After deciding which aspects would be assessed, who would assess them and when, the tutors developed seven rubrics (drafting process, assessment of the written thesis by the supervisor and by a panel, student self-assessment, peer assessment, tutor evaluation of the peer assessment and panel assessment of the viva). We analysed the reliability (inter-rater and internal consistency) and validity (convergent and discriminant) of the rubrics, and also the relationship between the competences assessed and the final thesis mark. All the rubrics had internal consistency coefficients >0.80. The rubric for oral communication skills (viva) yielded inter-rater reliability of 0.95. Factor analysis indicated a unidimensional structure for all but one of the rubrics, the exception being the rubric for peer assessment, which had a two-factor structure. The main competences associated with a good quality Bachelor thesis were written communication skills and the ability to work independently. The assessment system based on seven rubrics is shown to be valid and reliable. Writing a Bachelor thesis requires a range of degree-level competences and it offers nursing students the opportunity to develop their evidence-based practice skills. Copyright © 2018 Elsevier Ltd.

Boeke, Caroline E.; Storfer-Isser, Amy; Redline, Susan; Taveras, Elsie M.

2014-01-01

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.

1992-01-01

In 1988 the Department of Health (DOH) recognized the cytology screener grade of laboratory staff. Cytology screeners have a 2 year training period after which they must sit a 'competence examination'. The British Society for Clinical Cytology offers an examination to meet the DOH specification. It consists of a written paper, a practical screening test, a spot test and a short viva voce. The screening test is paramount and candidates who miss a dyskaryotic smear cannot be successful. In the first 3 years there have been 22 examinations, 294 candidates and a pass rate of 76%. The majority of candidates were Cytology Screeners of 2-3 years experience but significant numbers of Medical Laboratory Scientific Officers (MLSOs) and senior MLSOs also chose to sit the examination.

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.

Gareau, Daniel

2014-03-01

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.

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.

Abdominal aortic aneurysm is the only cardiovascular disease targeted by population screening. In this study, we test the effect of screening and subsequent intervention for abdominal aortic aneurysm, peripheral arterial disease, and hypertension combined. In this randomised controlled trial, we randomly allocated (1:1) all men aged 65-74 years living in the Central Denmark Region to screening for abdominal aortic aneurysm, peripheral arterial disease, and hypertension, or to no screening. We based allocation on computer-generated random numbers from 1 to 100 in blocks of 1067 to 4392, stratified by 19 municipalities. Only the non-screening group and the investigator assessing outcomes were masked. We invited participants who were found to have abdominal aortic aneurysm or peripheral arterial disease back for confirmation and eventual initiation of relevant pharmacological therapy. We further offered participants with abdominal aortic aneurysm annual control or surgical repair. We referred participants with suspected hypertension to their general practitioner. The primary outcome was all-cause mortality, assessed 5 years after randomisation, analysed in all randomly allocated participants except for those who had incorrect person identification numbers. This trial is registered at ClinicalTrials.gov, number NCT00662480. Between Oct 8, 2008, and Jan 11, 2011, we randomly allocated 50 156 participants, with 25 078 (50%) each in the screening and non-screening groups. Four (<1%) participants in the screening group were lost to follow-up. After a median follow-up of 4·4 years (IQR 3·9-4·8), 2566 (10·2%) of 25 074 participants in the screening group and 2715 (10·8%) of 25 078 in the non-screening group had died. This finding resulted in a significant hazard ratio of 0·93 (95% CI 0·88-0·98; p=0·01), an absolute risk reduction of 0·006 (0·001-0·011), and a number needed to invite of 169 (89-1811). Incidences of diabetes (3995 per 100 000 person-years in the screening group vs 4129 per 100 000 person-years in the non-screening group), intracerebral haemorrhage (146 vs 140), renal failure (612 vs 649), cancer (3578 vs 3719), or 30 day mortality after cardiovascular surgery (44·57 vs 39·33) did not differ between groups. The observed reduction of mortality risk from abdominal aortic aneurysm, peripheral arterial disease, and hypertension has never been seen before in the population screening literature and can be linked primarily to initiation of pharmacological therapy. Health policy makers should consider implementing combined screening whether no screening or isolated abdominal aortic aneurysm screening is currently offered.

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

PurposeTo characterize the type, and the causes of visual impairment (VI) in various stages of early and late age-related macular degeneration (AMD) and the factors associated with visual impairment in subjects with AMDMethods6617 subjects ≥60 years were enumerated; 5495 (83.04%) participated in eye examination. Of which, 4791 subjects had gradable fundus images. AMD was graded per International ARM Epidemiological Study Group. Subjects underwent detailed ophthalmic exam. VI was defined per the WHO classification. Mild VI was defined as VA less than 6/12 to 6/18, moderate VI-VA less than 6/18 but up to 6/60, severe VI-VA less than 6/60 but up to 3/60 and legal blindness-VA worse than 3/60. Factors associated with VI in AMD was analyzed with univariate and logistic regression analysis.ResultsNine hundred and eighty-eight subjects were identified as having AMD (893 with early AMD and 95 with late AMD); 85% of the subjects (95% CI: 82.7-87.1) had no VI, 13.1% had mild VI (95% CI: 11.1-15.3), 0.8% had severe VI (95% CI: 0.4-1.6), 1.1% had legal blindness (95% CI: 0.6-1.9). Prevalence of any VI was 13.7% in early AMD and 27.4% in late AMD, P=0.0004; age group 65-70 years (OR=1.89, 95% CI: 1.16-3.08, P=0.011), and those ≥75 years (OR=3.67, 95% CI: 1.95-6.91, P=0.0001) had greater odds of VI compared with age group 60-64 years. Male gender was a protective factor for VI (OR=0.57, CI: 0.36-0.90, P=0.016). Cataract (31.8%) and refractive error (28.4%) accounted for a majority of the VI.ConclusionsCataract and refractive error account for a significant proportion of VI in the south Indian population with AMD. Early AMD is the third leading cause of VI. Greater age and female gender are associated with VI in subjects with AMD.

Changes in the contents of carotenoids and their true retentions (% TR) during the production of puree of Cucurbita moschata 'Menina Brasileira' and of Cucurbita maxima 'Exposição' pumpkins and the stability of such compounds during 180days of storage were monitored by liquid chromatography coupled with a photodiode array detector. Cooking caused higher losses than commercial sterilisation. High losses of xanthophylls such as lutein and violaxanthin were noted during processing and storage of pumpkin puree. Such losses show the low stability of these compounds. The major carotenoids, pro-vitamin A carotenes, namely, α-carotene and all-trans-β-carotene for C. moschata 'Menina Brasileira' and all-trans-β-carotene for C. maxima 'Exposição' obtained high retentions (>75%) after processing. A slight degree of isomerisation of β-carotene was noted in the puree samples, but with low concentrations of cis-isomers. Storage for 180days did not significantly affect (P⩽0.05) the concentrations of these carotenoids. Copyright © 2011 Elsevier Ltd. All rights reserved.

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.

Cost-effectiveness of population-based vascular disease screening and intervention in men from the Viborg Vascular (VIVA) trial.

Søgaard, R; Lindholt, J S

2018-04-25

Population-based screening and intervention for abdominal aortic aneurysm, peripheral artery disease and hypertension was recently reported to reduce the relative risk of mortality among Danish men by 7 per cent. The aim of this study was to investigate the cost-effectiveness of vascular screening versus usual care (ad hoc primary care-based risk assessment) from a national health service perspective. A cost-effectiveness evaluation was conducted alongside an RCT involving all men from a region in Denmark (50 156) who were allocated to screening (25 078) or no screening (25 078) and followed for up to 5 years. Mobile nurse teams provided screening locally and, for individuals with positive test results, referrals were made to general practices or hospital-based specialized centres for vascular surgery. Intention-to-treat-based, censoring-adjusted incremental costs (2014 euros), life-years and quality-adjusted life-years (QALYs) were estimated using Lin's average estimator method. Incremental net benefit was estimated using Willan's estimator and sensitivity analyses were conducted. The cost of screening was estimated at €148 (95 per cent c.i. 126 to 169), and the effectiveness at 0·022 (95 per cent c.i. 0·006 to 0·038) life-years and 0·069 (0·054 to 0·083) QALYs, generating average costs of €6872 per life-year and €2148 per QALY. At a willingness-to-pay threshold of €40 000 per QALY, the probabilities of cost-effectiveness were 98 and 99 per cent respectively. The probability of cost-effectiveness was 71 per cent when all the sensitivity analyses were combined into one conservative scenario. Vascular screening appears to be cost-effective and compares favourably with current screening programmes. © 2018 BJS Society Ltd Published by John Wiley & Sons Ltd.

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.

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.

The UK Intercollegiate Specialty Board examination in Surgical Neurology was established in 1991 based on the experience of the original Royal College of Surgeons of Edinburgh Assessment in Surgical Neurology, an exit examination that was originally opposed both by surgery in general and by the younger neurosurgical community. Criteria for eligibility encompass both UK, EC and non-EC overseas graduates. Candidates must have completed satisfactorily their 4th year of a 6 year training programme, have personal experience with the more straightforward benign tumours, aneurysms and posterior fossa explorations, and be able to safely manage a conventional neurosurgical practice. The examination consists of a multiple choice question paper, clinical examination and three Vivas. A curriculum is under construction. Examinations are held twice per annum, and rotate between the four colleges. There are strict guidelines for the examiners. The pass rate is about 70%. All aspects of the examination continue to evolve and are carefully audited.

Ethnic newspapers have the potential to reach and influence various cultural and ethnic subpopulations traditionally underserved in the United States. The current study sought to explore how ethnic news consumption interacts with health motivation to predict cancer prevention behaviors in a sample of Spanish-speaking adults. Participants (N = 100) completed a survey in Spanish, with items measuring demographics, acculturation, health literacy, health motivation, ethnic newspaper consumption (for two papers: La Viva and La Raza), and cancer prevention behaviors. Results indicated consumption of ethnic newspapers correlated positively to acculturation, and cancer screening utilization. In hierarchical regression analyses, the interaction of consumption of an ethnic newspaper (La Raza) and health motivation predicted two of the six prevention behaviors assessed: avoidance of fatty foods and screening behavior. The study provides evidence that consumption of Spanish-language newspapers enhances the likelihood that individuals with high levels of health motivation will engage in healthy behaviors. This finding highlights the utility of utilizing Spanish-language newspapers to reach underserved populations.

Analysis of factors associated with traffic accidents of cyclists attended in Brazilian state capitals.

Brazil has the sixth largest bicycles fleet in the world and bicycle is the most used individual transport vehicle in the country. Few studies address the issue of cyclists' accidents and factors that contribute to or prevent this event. VIVA is a cross-sectional survey and is part of the Violence and Accidents Surveillance System, Brazilian Ministry of Health. We used complex sampling and subsequent data review through multivariate logistic regression and calculation of the respective odds ratios. Odds ratios showed greater likelihood of cyclists' accidents in males, people with less schooling and living in urban and periurban areas. People who were not using the bike to go to work were more likely to suffer an accident. The profile found in this study corroborates findings of other studies. They claim that the coexistence of cyclists and other means of transportation in the same urban space increases the likelihood of accidents. The construction of bicycle-exclusive spaces and educational campaigns are required.

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

Since it was opened 18 months ago, the blood donor sampling Center at Orsay has used traditional means of advertising. However, although the results were satisfactory for the first year, they soon levelled off; and it was decided to adopt another approach, in the form a promotion campaign, including posters, brochures, cartoons... The campaign "Vive la Vie" has been limited to the immediate vicinity of Orsay. It was set up in such a way to enable the staff to implement it easily and progressively and thus precisely follow and record the results. The data are reported in this article. The advantages of the system are a two-step appeal which allows more persuasive information to be given; a graduated approach welcoming both the convinced and the more reluctant donors to the Centre; and the compiling of an index by means of the forms returned by the population.

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.

This essay proposes a reflection on different perspectives for analyzing the Brazilian Journal of Nursing. The journal, which is considered an instrument for the diffusion of knowledge and ideology of the nursing field, has been the object of few studies. In this essay, the authors adopt as theoretical reference the signification triangle of Pierre Levy and aspects of the feminist theory. The authors believe the journal should be analyzed as an object that produces, in its relation with nursing professionals, elements that constitute a culture, knowledge and symbology of the Brazilian nursing.

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. Mechanical ventilation in the asthma attack has been one of the updated topics. Describe the most important topics on the mechanical ventilation during the asthma attack and suggest the main therapeutic approaches. Systematic review of the published literature and gradation of the studies in levels of evidence, using the key words "mechanical ventilation" and "asthma". We present recommendations on the ventilatory modes and settings to be adopted when ventilating a patient during an asthma attack, as well as the recommended monitoring. Alternative ventilation techniques are also presented. Protective ventilatory strategies are recommended when ventilating a patient during a severe asthma attack.

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).

Objective: 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. Methods: 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). Results: 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). Conclusion: 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. PMID:27026971

The aim of this article was to describe the profile of emergency care for injuries resulting from violence against children (< 10 years of age) treated Surveillance System for Violence and Accidents (VIVA) of the Ministry of Health, for 30 consecutive days in 2006 and 2007 in selected cities of Brazil. The 518 children in the sample were predominantly male (60.6%), aged 5-9 years (52.1%), and black (71.2%). The majority (55%) of the cases occurred in the home, 34.2% involved sharp objects, and 68.7% evolved to discharge. The most frequent form of violence was physical aggression (67.4%), involving beating, sharp objects, and firearms. The other types of violence included neglect (32%), psychological abuse (9.5%), and sexual assault (3.5%). The aggressors were largely male (48.1%) and family members of the victim (36.3%). The study shows children's vulnerability to situations of violence. It is necessary to develop specific strategies for inter-sector care and social mobilization to intervene in this problem.

This study explored the association between demographic characteristics (age and sex) and other variables related to violence committed against children (form of violence perpetrator, place of occurrence, and nature of injury) using a sample of 404 children taken from the 2014 Violence and Accident Surveillance System (Sistema de Vigilância de Violências e Acidentes, VIVA) survey. 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.

Émilie Du Châtelet's interpretation of the laws of motion in the light of 18th century mechanics.

PubMed

Reichenberger, Andrea

2018-06-01

Émilie Du Châtelet is well known for her French translation of Newton's Philosophiae Naturalis Principia Mathematica. It is the first and only French translation of Newton's magnum opus. The complete work appeared in 1759 under the title Principes mathématiques de la philosophie naturelle, par feue Madame la Marquise Du Chastellet. Before translating Newton's Principia, Du Châtelet worked on her Institutions de physique. In this book she defended the Leibnizian concept of living forces - vis viva. This paper argues that both of these works were part of a critical transformation and consolidation of post-Newtonian mechanics in the early 18th century, beyond Newton and Leibniz. This will be shown by comparing Du Châtelet's translation of Newton's axioms with her own formulations of the laws of motion in light of Thomas Le Seur's and François Jacquier's Geneva edition which holds a special place among the several editions of the Principia that appeared in the early 18th century.

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.

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.

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.

2017-01-01

A high proportion of children have overweight and obesity in the United States and other countries. Accurate assessment of anthropometry is essential to understand health effects of child growth and adiposity. Gold standard methods of measuring adiposity, such as dual X-ray absorptiometry (DXA), may not be feasible in large field studies. Research staff can, however, complete anthropometric measurements, such as body circumferences and skinfold measurements, using inexpensive portable equipment. In this protocol we detail how to obtain manual anthropometric measurements from children, including standing and sitting height, weight, waist circumference, hip circumference, mid-upper arm circumference, triceps skinfold thickness, and subscapular skinfold thickness, and procedures to assess the quality of these measurements. To demonstrate accuracy of these measurements, among 1,110 school-aged children in the pre-birth cohort Project Viva we calculated Spearman correlation coefficients comparing manual anthropometric measurements with a gold standard measure of body fat, DXA fat mass1. To address reliability, we evaluate intra-rater technical error of measurement at a quality control session conducted on adult female volunteers. PMID:28191881

2012-06-01

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

To analyze concepts of gender and sexuality present in the field of sex therapeutic interventions. An ethnographic observation was conducted, and it was completed with the analysis of printed material originated from the X Congresso Brasileiro de Sexualidade Humana (10th Brazilian Congress on Human Sexuality), promoted by the Sociedade Brasileira de Estudos em Sexualidade Humana (Brazilian Society of Human Sexuality Studies), and the VIII Congresso Brasileiro sobre Inadequações Sexuais (8th Brazilian Congress on Sexual Inadequacies), promoted by the Associação Brasileira para o Estudo das Inadequações Sexuais (Brazilian Association of Sexual Inadequacy Studies), both held in 2005. The analysis emphasized the interaction between the quantitative perspective in the processing of the variables (participants' gender and profession and lecture topics) and the qualitative perspective in the analysis and interpretation of the more general set of data. The topics of sessions and focus of presentations suggest that the field is divided by the contrast between two medical specialties: gynecology and urology, the former is aimed at female and couple dysfunctions, while the latter is aimed at male dysfunctions. Male sexuality is approached from the predominantly biomedical perspective, centered on the physiology of erection and drug prescription, whereas female sexuality is considered to be conditioned by relationship problems, when psychological intervention is more adequate.

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.

ABSTRACT Here, we describe the percentage of non-citation in Brazilian public health journals, a field that, until now, had not been investigated nationally or internationally. We analyzed articles, published between 2008 and 2012, of eight public health journals indexed in the scopus database. The percentage of non-citation differs between journals (from 5.7% to 58.1%). We identified four statistically distinct groups: História, Ciência, Saúde – Manguinhos (58% uncited articles); Physis: Revista de Saúde Coletiva, Interface, and Saúde e Sociedade (32% to 37%); Ciência & Saúde Coletiva and Revista Brasileira de Epidemiologia (16% to 17%); and Cadernos de Saúde Pública and Revista de Saúde Pública (6%). The non-citation in the first three years post-publication also varies according to journal. Four journals have shown a clear decline of non-citation: Cadernos de Saúde Pública, Ciência & Saúde Coletiva, Revista Brasileira de Epidemiologia, and Physis. Another three (Revista de Saúde Pública, Saúde e Sociedade, and Interface) presented an oscillation in non-citation, but the rates of 2008 and 2012 are similar, with different magnitudes. In turn, the journal História, Ciência, Saúde – Manguinhos maintains high rates of non-citation. Multidisciplinary journals attract more citation, but a comprehensive citation model still needs to be formulated and tested. PMID:29211202

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.

Probiotics exert a beneficial effect on the host through modulation of gastrointestinal microflora. The aim of this study was to investigate the effect of the probiotic Lactobacillus plantarum 299v on gut barrier function and the systemic inflammatory response in critically ill patients. One hundred and three critically ill patients were randomised to receive an oral preparation containing L. plantarum 299v (ProViva) in addition to conventional therapy (treatment group, n = 52) or conventional therapy alone (control group, n = 51). Serial outcome measures included gastric colonisation, intestinal permeability (lactulose/rhamnose dual-sugar probe technique), endotoxin exposure (IgM EndoCAb), C-reactive protein and Interleukin 6 levels. L. plantarum had no identifiable effect on gastric colonisation, intestinal permeability, endotoxin exposure or serum CRP levels. There were no differences between the groups in terms of septic morbidity or mortality. On day 15 serum IL-6 levels were significantly lower in the treatment group compared to controls. The enteral administration of L. plantarum 299v to critically ill patients was associated with a late attenuation of the systemic inflammatory response. This was not accompanied by any significant changes in the intestinal microflora, intestinal permeability, endotoxin exposure, septic morbidity or mortality.

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.

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.

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.

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.

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.

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.

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

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.

The aim of the study was to characterize the profile of victims of self-inflicted injuries, who were attended at urgent and emergency care services in Brazilian state capitals, by using the "Viva Survey" database of 2014. Descriptive statistics of the self-inflicted injuries by gender, as well as logistic regression analysis, were performed. The evaluated characteristics were age, gender, race/skin color, education, area of residence, characteristics of the event, alcohol use and the outcome of the case. The results showed that almost 10% of the surveyed cases that were treated by emergency medical services in relation to violence were due to self-inflicted injuries: of particular note were the cases involving females and adults. Gender differences were found, including some that were related to the method chosen to commit suicide. It was not possible to evaluate some factors that are generally associated with suicide attempts because the necessary information was not within the scope of the instrument used for data collection. It was concluded that emergency medical services are very important in terms of studies regarding suicide because they are the gateway to such cases. However, given its sensitive nature, the information issued by emergency medical services is very restricted. Consequently, patients need appropriate follow-up to prevent further suicide attempts.

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

Equalization and Participation for All: Swedish Disability Policy at a Crossroads.

Axelson, Hans von; Lindén, Arvid; Andersson, Jonas E; Skehan, Terry

2016-01-01

The political line in Swedish disability policy advocates the use of generalized solutions in order to fit potential needs of the largest possible group of people and, where needed, special solutions to bridge the remaining gap between the generalized level of accessibility and additional individual needs. This is referred to as the disability perspective (DP). The DP has embraced two tracks: one that pertains to generalized solutions that promote an overall high level of accessibility and usability, and another one that pertains to different types of individual support for people with disabilities. The present study is a self-reflective inquiry on key issues for the development of future disability policies. Five experts entered a discussion about the pros and cons concerning the DP. This confirmed or refuted assumptions, dilemmas, themes as well as reoccurring patterns in the political viva voce procedure that has formed the contemporary disability policy. Over the course of time, the experts believed that the DP had nurtured a belief that there is a dichotomy. This may have created an imbalance in the relation between the DP and policies such as those concerning healthcare and social care. With a clearer focus on interdependence, the experts saw synergies between needs for assistive technology, assistive products and the requirements for the built environment.

Background Prenatal exposure to traffic pollution has been associated with faster infant weight gain, but implications for cardiometabolic health in later childhood are unknown. Methods Among 1,418 children in Project Viva, a Boston-area pre-birth cohort, we assessed anthropometric and biochemical parameters of cardiometabolic health in early (median age 3.3 years) and mid- (median age 7.7 years) childhood. We used spatiotemporal models to estimate prenatal and early life residential PM2.5 and black carbon exposure as well as traffic density and roadway proximity. We performed linear regression analyses adjusted for sociodemographics Results Children whose mothers lived close to a major roadway at the time of delivery had higher markers of adverse cardiometabolic risk in early and mid-childhood. For example, total fat mass was 2.1kg (95%CI: 0.8, 3.5) higher in mid-childhood for children of mothers who lived < 50 m vs. ≥ 200m from a major roadway. Black carbon exposure and traffic density were generally not associated with cardiometabolic parameters, and PM2.5 exposure during the year prior was paradoxically associated with improved cardiometabolic profile Conclusions Infants whose mothers lived close to a major roadway at the time of delivery may be at later risk for adverse cardiometabolic health.

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.

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. PMID:19386406

It is a comparative study of the characteristics of gestation and childbirth of girls aged up to 13 who have had children, without or with notification of rape, in the Violence & Accidents Vigilance (VIVA) System of the Brazilian Case Registry Database (Sistema de Informação de Agravos de Notificação - SINAN). A significant percentage (67.5%) of the girls aged up to 13 with children were of the black race/color category. There was repeated violence in 58.2% of cases. The notified rape victims have a higher percentage of birth by cesarean section, late onset and a lower number of prenatal consultations; and their babies had lower birthweight and lower 1-minute Apgar scores than mothers without rape notification. Rape of children and adolescents is an important risk factor that has repercussions during pregnancy, and complications in delivery and childbirth.

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.

Perspectives on invasive and noninvasive ventilatory support for critically ill patients are evolving, as much evidence indicates that ventilation may have positive effects on patient survival and the quality of the care provided in intensive care units in Brazil. For those reasons, the Brazilian Association of Intensive Care Medicine (Associação de Medicina Intensiva Brasileira - AMIB) and the Brazilian Thoracic Society (Sociedade Brasileira de Pneumologia e Tisiologia - SBPT), represented by the Mechanical Ventilation Committee and the Commission of Intensive Therapy, respectively, decided to review the literature and draft recommendations for mechanical ventilation with the goal of creating a document for bedside guidance as to the best practices on mechanical ventilation available to their members. The document was based on the available evidence regarding 29 subtopics selected as the most relevant for the subject of interest. The project was developed in several stages, during which the selected topics were distributed among experts recommended by both societies with recent publications on the subject of interest and/or significant teaching and research activity in the field of mechanical ventilation in Brazil. The experts were divided into pairs that were charged with performing a thorough review of the international literature on each topic. All the experts met at the Forum on Mechanical Ventilation, which was held at the headquarters of AMIB in São Paulo on August 3 and 4, 2013, to collaboratively draft the final text corresponding to each sub-topic, which was presented to, appraised, discussed and approved in a plenary session that included all 58 participants and aimed to create the final document.

Genome sequence of Prevotella intermedia SUNY aB G8-9K-3, a biofilm forming strain with drug-resistance.

PubMed

Moon, Ji-Hoi; Kim, Minjung; Lee, Jae-Hyung

Prevotella intermedia has long been known to be as the principal etiologic agent of periodontal diseases and associated with various systemic diseases. Previous studies showed that the intra-species difference exists in capacity of biofilm formation, antibiotic resistance, and serological reaction among P. intermedia strains. Here we report the genome sequence of P. intermedia SUNY aB G8-9K-3 (designated ATCC49046) that displays a relatively high antimicrobial resistant and biofilm-forming capacity. Genome sequencing information provides important clues in understanding the genetic bases of phenotypic differences among P. intermedia strains.

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.

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.

Ex vivo confocal microscopy: a new diagnostic technique for mucormycosis.

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.

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.

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.

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.

What does originality in research mean? A student's perspective.

PubMed

Edwards, Mandy

2014-07-01

To provide a student's perspective of what it means to be original when undertaking a PhD. A review of the literature related to the concept of originality in doctoral research highlights the subjective nature of the concept in academia. Although there is much literature that explores the issues concerning examiners' views of originality, there is little on students' perspectives. A snowballing technique was used, where a recent article was read, and the references cited were then explored. Given the time constraints, the author recognises that the literature review was not as extensive as a systematic literature review. It is important for students to be clear about what is required to achieve a PhD. However, the vagaries associated with the formal assessment of the doctoral thesis and subsequent performance at viva can cause considerable uncertainty and anxiety for students. Originality in the PhD is a subjective concept and is not the only consideration for examiners. Of comparable importance is the assessment of the student's ability to demonstrate independence of thought and increasing maturity so they can become independent researchers. This article expresses a different perspective on what is meant when undertaking a PhD in terms of originality in the doctoral thesis. It is intended to help guide and reassure current and potential PhD students.

We examined whether neighborhood-, friend-, and family- norms and social support for consumption and purchase of fruits and vegetables (F&V) were associated with F&V intake among low-income residents in subsidized housing communities. We examined baseline data from a study ancillary to the Live Well/Viva Bien intervention. Participants included 290 residents in four low-income subsidized housing sites who were ≥ 18 years of age, English and/or Spanish speaking, and without medical conditions that prevented consumption of F&V. Linear regression models examined associations of norms and social support with F&V intake after adjustments for sociodemographic characteristics. In the analysis, neighborhood social support for F&V was associated with a 0.31 cup increase in F&V intake (95% CI = 0.05, 0.57). The family norm for eating F&V and family social support for eating F&V were associated with a 0.32 cup (95% CI = 0.13, 0.52) and 0.42 cup (95% CI = 0.19, 0.64) increase in F&V intake, respectively. To our knowledge, no other studies have examined neighborhood, family, and peer norms and social support simultaneously and in relation to F&V intake. These findings may inform neighborhood interventions and community-level policies to reduce neighborhood disparities in F&V consumption.

To investigate child growth, cognitive/language development, and their environmental and biological determinants. This was a cross-sectional, predictive correlation study with all 92 children aged 24-36 months who attended the municipal early childhood education network in a town in the Vale do Jequitinhonha region, in 2011. The socioeconomic profile was determined using the questionnaire of the Associação Brasileira de Empresas de Pesquisa. The socio-demographicand maternal and child health profiles were created through a self-prepared questionnaire. The height-for-age indicator was selected to represent growth. Cognitive/language development was assessed through the Bayley Scale of Infant and Toddler Development. The quality of educational environments was assessed by Infant/Toddler Environment Scale; the home environment was assessed by the Home Observation for Measurement of the Environment. The neighborhood quality was determined by a self-prepared questionnaire. A multivariate linear regression analysis was performed. Families were predominantly from socioeconomic class D, with low parental education. The prevalence of stunted growth was 14.1%; cognitive and language development were below average at 28.6% and 28.3%, respectively. Educational institutions were classified as inadequate, and 69.6% of homes were classified as presenting a risk for development.

Analyze, quantitatively, which odontology magazines are being consulted and read by surgeon-dentists, and evaluate the profiles of the mostly cited. 370 polls were made, during the XVII Congresso Pernambucano de Odontologia (Pernambucan Congress of Odontology) and the IX Congresso de Odontologia do Rio Grande do Norte (Congress of Odontology of Rio Grande do Norte), which took place, respectively, in April and September 2004. The participants were volunteering professionals divided among General Practice (37.84%) and ten differing specialties (62.16%); of which 77.02% had up to ten years of graduation. Resulting the researches made, 620 quotes were generated, in which, 35 different magazines, national and international, were quoted. By analyzing the data collected, we observe that three magazines summed more than half of the quota (52.74%), which are: Revista da Associação Paulista de Cirurgiões Dentistas-APCP (Magazine of the Paulista Association of Surgeon-Dentists), Revista da Associação Brasileira de Odontologia - ABO national (Magazine of the Brazilian Association of Odontology) and the Revista Brasileira de Odontologia-RBO (Brazilian Magazine of Odontology). Despite the participants of the research being, in their majority, specialists, we observe a tendency of a greater consultation of the magazines of general characteristic. These magazines predominantly tackle clinical and technical subjects and present an expressive circulation, great penetration in the odontologic world, easy accessibility and a long time in the market (two of them are over 50 years-old). According to CAPES - QUALIS, all possess a B national concept. Therefore, it is necessary a deepening of this study, so as to analyze qualitatively what kind of subjects and themes these magazines touch, since they influence the odontologic formation and practice.

Successful use of sugammadex for caesarean section in a patient with myasthenia gravis.

PubMed

Soyoral, Lokman; Goktas, Ugur; Cegin, Muhammed Bilal; Baydi, Volkan

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.

Hereditary angioedema is an autosomal dominant disease characterized by recurrent angioedema attacks with the involvement of multiple organs. The disease is unknown to many health professionals and is therefore underdiagnosed. Patients who are not adequately diagnosed and treated have an estimated mortality rate ranging from 25% to 40% due to asphyxiation by laryngeal angioedema. Intestinal angioedema is another important and incapacitating presentation that may be the main or only manifestation during an attack. In this article, a group of experts from the "Associação Brasileira de Alergia e Imunologia (ASBAI)" and the "Grupo de Estudos Brasileiro em Angioedema Hereditário (GEBRAEH)" has updated the Brazilian guidelines for the diagnosis and treatment of hereditary angioedema.

The use of biopharmaceuticals dates from the 19th century and within 5-10 years, up to 50% of all drugs in development will be biopharmaceuticals. In the 1980s, the biopharmaceutical industry experienced a significant growth in the production and approval of recombinant proteins such as interferons (IFN α, β, and γ) and growth hormones. The production of biopharmaceuticals, known as bioprocess, involves a wide range of techniques. In this review, we discuss the technology involved in the bioprocess and describe the available strategies and main advances in microbial fermentation and purification process to obtain biopharmaceuticals.

Navarro, Rafael; Sánchez-Valverde, Josefina; Baltuille, José Manuel

2013-04-01

"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

Drugged Driving in Wisconsin: Oral Fluid Versus Blood.

Edwards, Lorrine D; Smith, Katherine L; Savage, Theodore

2017-07-01

A pilot project was conducted in Dane County, Wisconsin, to evaluate the frequency of individuals driving under the influence of drugs (DUID). Evidentiary blood specimens, collected from subjects arrested for Operating While Intoxicated (OWI), were compared to oral fluid (OF) results obtained with the Alere DDS2®, a handheld screening device. The project objectives were to evaluate (i) the Alere DDS2® for use by police officers in the field, (ii) the frequency of individuals DUID and drugs combined with alcohol among OWI cases, (iii) the differences between detecting drugs in OF and in blood, and (iv) the effect of the laboratory drug testing cancellation policy (LCP) when the blood alcohol concentration (BAC) exceeds 0.100 g/100 mL. Following the arrest and collection of blood, subjects were asked to voluntarily participate in the project and provide an OF specimen. The OF was presumptively screened with the Alere DDS2® for six drug categories including (ng/mL) amphetamine (50), benzodiazepines (temazepam, 20), cocaine (benzoylecgonine, 30), methamphetamine (50), opioids (morphine, 40) and THC (delta-9-THC, 25). Results obtained with the OF screening instrument were not confirmed. A total of 104 subjects (22 female, 82 male), ages 18-72, were included in the project. Blood specimens were tested by gas chromatography-headspace (GCHS-FID) for volatiles, enzyme immunoassay (Siemens Viva-E Drug Testing System), and an alkaline basic drug screen with gas chromatography-mass spectrometry (GCMS) analysis. To compensate for differences between the EIA and the Alere DDS2® drug categories, results from the enzyme immunoassay and the alkaline basic drug screen were combined for purposes of comparing OF to blood. Seventy-six of 104 (73%) subjects arrested for OWI were driving under the influence of alcohol; 71 of the 76 had a BAC exceeding 0.10 g/100 mL. Subjects with a BAC exceeding the LCP, screened positive for drugs in both OF (n = 29) and blood (n = 28). Overall, one

Cutaneous mucormycosis in advanced HIV disease.

PubMed

Moreira, José; Ridolfi, Felipe; Almeida-Paes, Rodrigo; Varon, Andrea; Lamas, Cristiane C

Angionvasive mucormycosis is an emerging fungal disease known to affect mainly diabetics or subjects with profound neutropenia. Infection usually occurs through the inhalation route, but cutaneous inoculation may occur after trauma or burns. However, mucormycosis remains unusual in HIV infection. We report a fatal case of cutaneous mucormycosis due to Rhizopus arrhizus involving the scalp following herpes zoster infection. The patient was a 42-year-old man with advanced AIDS failing on salvage antiretroviral therapy. The fungus was diagnosed on the basis of histopathology and culture. Our case emphasizes the need to consider mucormycosis in the differential diagnosis of necrotic cutaneous lesions in patients with late-stage HIV disease.

Maruyama, Yuta; Shigemura, Tomonari; Aoyama, Koki; Nagano, Noriyuki; Nakazawa, Yozo

Herein we report the case of a 10-year-old boy with an autosomal mosaic mutation who developed bacteremia. The causative agent was identified as Moraxella osloensis by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and 16S rRNA gene sequencing. In the pediatric population, there have been 13 case reports of infection attributed to M. osloensis and this is the fifth reported case of pediatric bacteremia due to M. osloensis. After Moraxella species infection was confirmed, the patient recovered with appropriate antimicrobial therapy. It is important to consider that M. osloensis can cause serious infections, such as bacteremia, in otherwise healthy children. Copyright © 2018 Sociedade Brasileira de Infectologia.

This analysis of Brazil's first medical newspapers - Propagador das Ciências Médicas (1827-28); Semanário de Saúde Pública (1831-33); Diário de Saúde (1835-36); Revista Médica Fluminense (1835-41); Revista Médica Brasileira (1841-43) - shows how Rio de Janeiro's socio-cultural context made it possible for this type of publication to emerge within the city's dynamic, troubled environment of the 1820s and 30s. I argue that the distinguishing feature of Brazil's early medical journalism was a symbiosis between business (local publishing houses' commercial interests), politics (struggles for political hegemony during the consolidation of the Imperial State), and science (the movement to institutionalize medicine and affirm it as a science).

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 L 1 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.

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.

To examine associations of chronic insufficient sleep with mid-childhood cardiometabolic health. At 6 months and yearly from 1 to 7 years, mothers participating in the Project Viva cohort reported children's 24-h sleep duration. The main exposure was a sleep curtailment score, ranging from 0 (maximal curtailment) to 13 (never having curtailed sleep). The main outcome was a mid-childhood metabolic risk score, derived as the mean of five sex- and cohort-specific z scores for waist circumference, systolic blood pressure, HDL cholesterol (scaled inversely), and log-transformed triglycerides and HOMA-IR; higher scores indicate higher risk. The mean (SD) sleep score was 10.0 (2.8); 5.1% scored 0-4, 13.9% scored 5-7, 14.1% scored 8-9, 28.7% scored 10-11, and 38.3% scored 12-13. Mean (SD, range) metabolic risk score was -0.03 (0.6, -1.8 to 2.6). In multivariable models, the metabolic risk score difference for children with most versus least curtailed sleep was 0.29 units (95% confidence interval [CI]: 0.02, 0.57). Further adjustment for mid-childhood BMI z score attenuated this difference to 0.08 units (95% CI: -0.14, 0.30). Chronic insufficient sleep from infancy to school-age was associated with higher mid-childhood metabolic risk. This association was explained by sleep duration's influence on mid-childhood adiposity. © 2014 The Obesity Society.

Local knowledge of traditional fishermen on economically important crabs (Decapoda: Brachyura) in the city of Conde, Bahia State, Northeastern Brazil

PubMed Central

2012-01-01

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.

Abstract Problem 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. Approach 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. Local setting Key populations in Brazil can have 40 times higher HIV prevalence than the general population (14.8% versus 0.4%). Relevant changes 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). Lessons learnt 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. PMID:27516641

Carlos-Vivas, J, Freitas, TT, Cuesta, M, Perez-Gomez, J, De Hoyo, M, and Alcaraz, PE. New tool to control and monitor weighted vest training load for sprinting and jumping in soccer. J Strength Cond Res XX(X): 000-000, 2018-The purpose of this study was to develop 2 regression equations that accurately describe the relationship between weighted vest loads and performance indicators in sprinting (i.e., maximum velocity, Vmax) and jumping (i.e., maximum height, Hmax). Also, this study aimed to investigate the effects of increasing the load on spatio-temporal variables and power development in soccer players and to determine the "optimal load" for sprinting and jumping. Twenty-five semiprofessional soccer players performed the sprint test, whereas a total of 46 completed the vertical jump test. Two different regression equations were developed for calculating the load for each exercise. The following equations were obtained: % body mass (BM) = -2.0762·%Vmax + 207.99 for the sprint and % BM = -0.7156·%Hmax + 71.588 for the vertical jump. For both sprinting and jumping, when the load increased, Vmax and Hmax decreased. The "optimal load" for resisted training using weighted vest was unclear for sprinting and close to BM for vertical jump. This study presents a new tool to individualize the training load for resisted sprinting and jumping using weighted vest in soccer players and to develop the whole force-velocity spectrum according to the objectives of the different periods of the season.

To investigate possible bias due to gender combination of students, role players and examiners in a high-stakes assessment. Valid oral interactive contextualized examinations (VOICEs) is a long-station OSCE-style exam in general practice (GP). At the time of writing it consisted of 65% of the student's final GP mark. In the VOICE, students undertake six tasks--four vivas and two role-plays. "Patient" roles are taken by professional role players who work regularly on the undergraduate curriculum. During the role-play, the student's clinical competence is assessed by an observing GP examiner. The communication skills marks are awarded by the role player and the examiner together, by negotiation. Data have been recorded detailing the role player's initial marks, the examiner's initial marks and their final (awarded) agreed marks for 1024 consultations. 512 final year medical students, 28 role players and 48 examiners. There were no inclusion or exclusion criteria. All those present on exam day became part of the data. There was a significant relationship between gender and performance for some, but not all, stations. Correlations for multiple comparisons removed the significance. Female students perform better across the board than male students. While not always significant, this did affect grading. There was no significant association between the genders of role players and examiners with the question choices. There has been a significant worsening of male results since 1999. Differences exist in the way that pairs of mixed or single genders score students.

Em indivíduos de 40 a 75 anos submetidos consecutivamente a avaliação rotineira de saúde em um único centro, quatro critérios de elegibilidade para estatina foram definidos: BR-1, BR-2 (LDL-c acima ou pelo menos 30 mg/dL acima da meta preconizada pela diretriz brasileira, respectivamente), EUA-1 e EUA-2 (risco estimado pelas PCE em 10 anos ≥ 5,0% ou ≥ 7,5%, respectivamente). Foram estudados 13.947 indivíduos (48 ± 6 anos, 71% homens). A maioria dos indivíduos de risco intermediário ou alto pela V Diretriz apresentou risco calculado pelas PCE baixo e mais de 70% daqueles considerados de alto risco o foram devido à presença de fator agravante. Foram elegíveis para estatina 24%, 17%, 4% e 2% das mulheres pelos critérios BR-1, BR-2, EUA-1 e EUA-2, respectivamente (p < 0,01). Os respectivos valores para os homens foram 75%, 58%, 31% e 17% (p < 0,01). Oitenta e cinco por cento das mulheres e 60% dos homens elegíveis para estatina pelo critério BR-1 não seriam candidatos pelo critério EUA-1. Comparada à diretriz norte-americana, a V Diretriz Brasileira considera uma proporção substancialmente maior da população como elegível para estatina em prevenção primária. Isso se relaciona com discrepâncias entre o risco estratificado pela diretriz brasileira e o calculado pelas PCE, particularmente devido à reclassificação de risco baseada em fatores agravantes.

2017-01-01

Objective Our study aimed to assess Turkish publications in Science Citation Index (SCI) and Science Citation Index Expanded (SCI-E) indexed journals in the field of ‘anaesthesiology’. Methods Journals related to ‘anaesthesiology’ in the Science Citation Index-Expanded database of ‘Thomson Reuter Web of Science’ were searched. The search engine of Institute for Scientific Information (ISI) Web of Science (WoS) was used in the advanced mode by typing ‘IS=ISSN number’ to identify publications in the journal. By typing ‘IS=ISSN number AND CU=Turkey’, Turkish papers on anaesthesiology were found. If Turkish and non-Turkish authors had collaborated, the article was included in the search when the corresponding author had provided a Turkey-based address. The catalogue information and statistics were used to determine Turkish publications as the percentage of total publications and the annual mean number of Turkish publications. In WoS, ‘SU=anesthesiology’ was used to determine the number, country, year and topic distributions of publications from 1975 to date and within the last 10 years. The citation numbers and h-indices were determined based on the country for publications within the last 10 years. Results From 1975 to the early 2000s Turkey was 20th in the list of countries with highest number of publications on anaesthesiology, however in the last 10 years Turkey moved up to 18th place. Its mean citation number has been 4.64, and it remains the 2nd lowest country pertaining to citations among the 22 countries with the most number of publications. According to the percentage of publications in the field of anaesthesiology, the journals with highest rate of Turkish publications were Revista Brasileira de Anestesiologia, European Journal of Anaesthesiology and Journal of Anesthesia. Conclusion In the field of anaesthesiology, the highest number of articles from Turkey was published in Revista Brasileira de Anestesiologia, European Journal of

Nonextensive models for earthquakes.

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.

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.

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.

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.

Dark-field microscopic study of the interactions between gold/silver nanoparticles and giant unilamellar vesicles

NASA Astrophysics Data System (ADS)

Bhat, Anupama; Zhao, Jian; Cooks, Tiana; Ren, Jun; Lu, Qi

2018-02-01

Giant unilamellar vesicles (GUVs) are well-established model systems for studying lipid packing and membrane dynamics. With sizes larger than 1 μm, GUVs are easily observable using optical microscopy. Gold nanoparticles (AuNPs) are well known for their biocompatibility and such biomedical applications in drug and gene delivery as well as medical diagnostics and therapeutics. On the other hand, silver nanoparticles (AgNPs) have long been known for their potent antimicrobial and anti-inflammatory effects for such applications as wound dressing and biomedical implants. In this work, we employed the dark-field microscopy (CytoViva Inc.) to study the interactions between AuNPs/AgNPs and GUVs, respectively. The GUVs used in this study were prepared with 1,2 dimyristoyl-sn-glycero-3-phosphocholine (DMPC) as well as cholesterol (chol) at various mol% concentrations (0, 10, 20, 30, 40%). The electroformed GUVs were allowed to incubate with gold or silver nanoparticles of various sizes (between 10 and 100 nm) for 2 hrs before microscopic examination. The experiment has shown that the size of nanoparticles is a critical factor that determines the penetration rate. In addition, the membrane rigidity increases with the molar concentration of cholesterol hence making the NP penetration more difficult. Comparative studies have been made between AuNPs and AgNPs in regard to NP penetration and loading rate as well as the morphological changes induced in GUVs. This work aims to better understand the mechanisms of AuNP/AgNP and membrane interactions for their respective future applications in nanomedicine and nanotechnology.

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.

Factors associated with differential uptake of seasonal influenza immunizations among underserved communities during the 2009-2010 influenza season.

Influenza vaccination coverage remains low and disparities persist. In New York City, a community-based participatory research project (Project VIVA) worked to address this issue in Harlem and the South Bronx by supplementing existing vaccination programs with non-traditional venues (i.e., community-based organizations). We conducted a 10 min survey to assess access to influenza vaccine as well as attitudes and beliefs towards influenza vaccination that could inform intervention development for subsequent seasons. Among 991 participants recruited using street intercept techniques, 63% received seasonal vaccine only, 11% seasonal and H1N1, and 26% neither; 89% reported seeing a health care provider (HCP) during the influenza season. Correlates of immunization among those with provider visits during the influenza season included being US-born, interest in getting the vaccine, concern about self or family getting influenza, an HCP's recommendation and comfort with government. Among those without an HCP visit, factors associated with immunization included being US born, married, interest in getting the vaccine, understanding influenza information, and concern about getting influenza. Factors associated with lack of interest in influenza vaccine included being born outside the US, Black and uncomfortable with government. In medically underserved areas, having access to routine medical care and understanding the medical implications of influenza play an important role in enhancing uptake of seasonal influenza vaccination. Strategies to improve vaccination rates among Blacks and foreign-born residents need to be addressed. The use of non-traditional venues to provide influenza vaccinations in underserved communities has the potential to reduce health disparities.

Approaches to learning for the ANZCA Final Examination and validation of the revised Study Process Questionnaire in specialist medical training.

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.

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.

How should gestational weight gain be assessed? A comparison of existing methods and a novel method, area under the weight gain curve

PubMed Central

Kleinman, Ken P; Oken, Emily; Radesky, Jenny S; Rich-Edwards, Janet W; Peterson, Karen E; Gillman, Matthew W

Background 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. Methods 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 post-partum. The analytic sample comprises 2016 participants in Project Viva, an observational prospective cohort study of pregnant women in Massachusetts. Results 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. Conclusions 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. PMID:17715174

Nonextensive models for earthquakes

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}r{sup 3}. 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 Geofisica.more » 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.« less

The dengue fever is a major public health problem in the world. In Brazil, in 2015, there were 1,534,932 cases, being 20,320 cases of severe form, and 811 deaths related to this disease. The distribution of Aedes aegypti, the vector, is extensive. Recently, Zika and Chikungunya viruses had arisen, sharing the same vector as dengue and became a huge public health issue. Without specific treatment, it is urgently required as an effective vector control. This article is focused on reviewing vector control strategies, their effectiveness, viability and economical impact. Among all, the Sterile Insect Technique is highlighted as the best option to be adopted in Brazil, once it is largely effectively used in the USA and Mexico for plagues related to agribusiness.

Wastewater from an anaerobic treatment plant at a slaughterhouse was analysed to determine the bacterial biodiversity present. Molecular analysis of the anaerobic sludge obtained from the treatment plant showed significant diversity, as 27 different phyla were identified. Firmicutes, Proteobacteria, Bacteroidetes, Thermotogae, Euryarchaeota (methanogens), and msbl6 (candidate division) were the dominant phyla of the anaerobic treatment plant and represented 21.7%, 18.5%, 11.5%, 9.4%, 8.9%, and 8.8% of the total bacteria identified, respectively. The dominant bacteria isolated were Clostridium, Bacteroides, Desulfobulbus, Desulfomicrobium, Desulfovibrio and Desulfotomaculum. Our results revealed the presence of new species, genera and families of microorganisms. The most interesting strains were characterised. Three new bacteria involved in anaerobic digestion of abattoir wastewater were published. Copyright © 2015 Sociedade Brasileira de Microbiologia. Published by Elsevier Editora Ltda.

Correia, Mariana; dos Santos, Angela; Lages, Neusa; Correia, Carlos

2016-01-01

Steinert's disease is an intrinsic disorder of the muscle with multisystem manifestations. Myotonia may affect any muscle group, is elicited by several factors and drugs used in general anesthesia like hypnotics, sedatives and opioids. Although some authors recommend the use of regional anesthesia or combined anesthesia with low doses of opioids, the safest anesthetic technique still has to be established. We performed a continuous spinal anesthesia in a patient with Steinert's disease undergoing laparoscopic cholecystectomy using 10mg of bupivacaine 0.5% and provided ventilatory support in the perioperative period. Continuous spinal anesthesia was safely used in Steinert's disease patients but is not described for laparoscopic cholecystectomy. We reported a continuous spinal anesthesia as an appropriate technique for laparoscopic cholecystectomy and particularly valuable in Steinert's disease patients.

A letter sent in 1982 by a group of scientists to the president of Conselho Nacional de Desenvolvimento Científico e Tecnológico appealed for a policy of preservation of Brazilian scientific culture. The name of Carlos Chagas Filho topped the list of signatures thereby proving his commitment to that proposal, the ideological structure of which was part of his experience in scientific policy in Brazil and abroad. This document harks back to the practice of the history of the sciences in Brazil and the creation of places for the safeguard and organization of scientific memory, such as the Museu de Astronomia e Ciências Afins, Casa de Oswaldo Cruz and the Sociedade Brasileira de História da Ciência, of which Carlos Chagas Filho was an inaugural member of the board of directors.

Screening of freshwater fungi for decolorizing multiple synthetic dyes.

PubMed

Yang, Panpan; Shi, Wenxiao; Wang, Hongkai; Liu, Hongmei

The biodegradation of synthetic dyes by fungi is emerging as an effective and promising approach. In the present study, freshwater fungal strains isolated from submerged woods were screened for the decolorization of 7 synthetic dyes. Subsequently, 13 isolates with high decolorization capability were assessed in a liquid system; they belonged to 9 different fungal species. Several strains exhibited a highly effective decolorization of multiple types of dyes. New absorbance peaks appeared after the treatment with 3 fungal strains, which suggests that a biotransformation process occurred through fungal biodegradation. These results showed the unexploited and valuable capability of freshwater fungi for the treatment of dye-containing effluents. The ability of certain fungi to decolorize dyes is reported here for the first time. Copyright © 2016 Sociedade Brasileira de Microbiologia. Published by Elsevier Editora Ltda. All rights reserved.

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.

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 bla TEM and bla CTX-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.

Paraburkholderia tropica (syn Burkholderia tropica) are nitrogen-fixing bacteria commonly found in sugarcane. The Paraburkholderia tropica strain Ppe8 is part of the sugarcane inoculant consortium that has a beneficial effect on yield. Here, we report a draft genome sequence of this strain elucidating the mechanisms involved in its interaction mainly with Poaceae. A genome size of approximately 8.75Mb containing 7844 protein coding genes distributed in 526 subsystems was de novo assembled with ABySS and annotated by RAST. Genes related to the nitrogen fixation process, the secretion systems (I, II, III, IV, and VI), and related to a variety of metabolic traits, such as metabolism of carbohydrates, amino acids, vitamins, and proteins, were detected, suggesting a broad metabolic capacity and possible adaptation to plant association.

The aim of this study was to examine the association between religiousness and blood donation among postgraduate students. The Portuguese-language version of the Duke University Religion Index was administered to a sample of 226 Brazilian students with ages ranging from 22 to 55 years. All study participants had completed undergraduate courses in health-related areas. In the present study, 23.5% of the students were regular donors. Organizational religiousness was found to be associated with attitudes related to blood donation. This study also shows evidence that regular blood donors have a higher intrinsic religiousness than subjects who donate only once and do not return. This study shows that the attitudes concerning blood donation may have some association with religiosity. Copyright © 2014 Associação Brasileira de Hematologia, Hemoterapia e Terapia Celular.

The HIV-1 initial viral infection may present diverse clinical and laboratory course and lead to rapid, intermediate, or long-term progression. Among the group of non-progressors, the elite controllers are those who control the infection most effectively, in the absence of antiretroviral therapy (ART). In this paper, the TH1, TH2 and TH17 cytokines profiles are described, as well as clinical and laboratory aspects of an HIV-infected patient with undetectable viral load without antiretroviral therapy. Production of IL-6, IL-10, TNF-α, IFN-γ, and IL-17 was detected; in contrast IL-4 was identified. Host-related factors could help explain such a level of infection control, namely the differentiated modulation of the cellular immune response and a non-polarized cytokine response of the TH1 and TH2 profiles.

2005-03-01

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.

GeneXpert is one of the recent technological instruments used to diagnose tuberculosis in a short span of time. In this study, the performance of GeneXpert MTB/RIF assay for the diagnosis of extrapulmonary tuberculosis (EPTB) was compared with light-emitting diode Fluorescent Microscopy (LED-FM) in Khyber Pakhtunkhwa, Pakistan. A total of 737 EPTB samples were collected from tuberculosis (TB) suspected patients. Out of these samples, male to female ratio was 53% (n=390) to 47% (n=347) respectively. The sensitivity and specificity was 73% and 100% for GeneXpert, while 40% and 100% for LED-FM microscopy. This shows that the sensitivity of GeneXpert is 40-50%, higher than LED-FM microscopy. GeneXpert also detected low number of bacilli as compared to LED-FM microscopy. Copyright © 2018 Sociedade Brasileira de Microbiologia. Published by Elsevier Editora Ltda. All rights reserved.

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.

Most Escherichia coli strains live harmlessly in the intestines and rarely cause disease in healthy individuals. Nonetheless, a number of pathogenic strains can cause diarrhea or extraintestinal diseases both in healthy and immunocompromised individuals. Diarrheal illnesses are a severe public health problem and a major cause of morbidity and mortality in infants and young children, especially in developing countries. E. coli strains that cause diarrhea have evolved by acquiring, through horizontal gene transfer, a particular set of characteristics that have successfully persisted in the host. According to the group of virulence determinants acquired, specific combinations were formed determining the currently known E. coli pathotypes, which are collectively known as diarrheagenic E. coli. In this review, we have gathered information on current definitions, serotypes, lineages, virulence mechanisms, epidemiology, and diagnosis of the major diarrheagenic E. coli pathotypes.

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.

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.

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.

BACKGROUND: 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. METHOD: 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. RESULTS: 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]). CONCLUSIONS: More TV viewing, and, among racial/ethnic minority children, the presence of a bedroom TV, were associated with shorter sleep from infancy to midchildhood. PMID:24733878

Reflectance confocal microscopy (RCM) has been recently shown to be effective for measuring the Demodex mite density. To compare and demonstrate the advantages and disadvantages of standardized skin surface biopsy (SSSB) and RCM for measuring the density of Demodex mites. Forty-eight patients (30 female, 18 male) and 47 healthy controls (30 female, 17 male) were enrolled in the study. The patients diagnoses were pityriasis folliculorum (n = 40), papulopustulary rosecea (n = 7) and erythema-telengiectatic rosacea (n = 1). The area with the most intense erythema on the right cheek was selected for imaging with RCM (VivaScope 3000) and SSSB. Forty-two patients demonstrated high Demodex density [(Dd) > 5 mites/cm(2) ] with SSSB (85.7%). RCM identified demodicosis in 48 patients (100%). The mean Dd measured with RCM (409.8 ± 209.2) was significantly higher than SSSB (15.33 ± 18.1) (P < 0.001). In the patients, RCM demonstrated the mean number of mites 40.90 ± 20.9 and 4.11 ± 6.4 in the controls per 10 mm(2) area. The corresponding mean number of 2.63 ± 0.77 mites was detected in the infested follicles per area of view compared to a mean of 0.77 ± 0.98 mites in the infested follicles in the controls (P < 0.001). Reflectance confocal microscopy is a fast, direct and noninvasive method for Demodex-associated diseases and it is superior to SSSB for Demodex mite detection. © 2014 John Wiley & Sons A/S.

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.

2017-01-01

Transdermal drug delivery represents an extremely attractive and innovative route across the skin owing to the possibility for achieving systemic effect of drugs. The present scenario demands a special focus on developing safe medicine with minimized toxic adverse effects related to most of the pharmacologically active agents. Transdermal drug delivery would be a focal paradigm which provides patient convenience, first-pass hepatic metabolism avoidance, local targeting and reduction in toxic effect related to various categories of drugs like, analgesics, antiinflammatory, antibiotics, antiviral, anaesthetic, anticancer etc. Even this route has challenges due to highly organized structure of skin which acts as a main barrier to penetration of drug via the skin. Several alternative possible strategies are available which overcome these barriers, including use of penetration enhancer, eletroporation, iontophoresis and various nanotechnologically developed nanocarrier systems. The latest one includes employing liposome, dendrimers, nanoparticles, ethosome, carbon nanotube and many more to avoid associated limitations of conventional formulations. Numerous transdermal products such as Estrasorb, Diractin, VivaGel®, Daytrana®, Aczone, Sileryst® are available in the market having a novel strategy to achieve higher penetration of drugs. This encourages formulation fraternity to develop structurally deformable and stable nanocarriers as an alternative approach for controlled and reliable drug delivery across the skin barrier. In this review, we will discuss nanocarriers mediated approaches that come-up with the solutions to the different challenges towards transdermal drug delivery, its clinical importance and latest insight to research in it. The reports presented in this review confirm the wide application of nanocarriers for transdermal delivery of drug/gene.

To identify intervention categories encountered by physical therapists working in aquatic therapy with disabled children, using the International Classification of Functioning, Disability and Health-Children and Youth (ICF-CY). Aquatic physical therapists were asked to describe concepts related to the functioning of disabled children and their contextual factors. Data were collected in three rounds using the Delphi technique. All answers were translated ('linked') to the ICF-CY and analyzed to determine the degree of consensus. Answers were linked and organized into four diagnostic groups. Overall, in the four groups, 41 Body Functions, 8 Body Structures, 36 Activities and Participation, and 6 Environmental Factors categories were identified as intervention targets. In addition, 8 Environmental Factors that influence aquatic physical therapy were identified. This study highlights the variety of intervention categories available to aquatic physical therapists when treating children in the water.

General anesthesia is a safe, frequent procedure in clinical practice. Although it is very unusual in procedures not related to head and or neck surgery, vocal cord paralysis is a serious and important complication. Incidence has been associated with patient age and comorbidities, as well as the position of the endotracheal tube and cuff. It can become a dangerous scenario because it predisposes aspiration. To present a case and analyze the risk factors associated with increased risk of vocal cord paralysis described in the literature. 53 year-old diabetic man, who developed hoarseness in the postoperative period after receiving general anesthesia for an elective abdominal laparoscopic surgery. Otolaryngological evaluation showed left vocal cord paralysis. Vocal cord paralysis can be a serious complication of general anesthesia because of important voice dysfunction and risk of aspiration. The management is not yet fully established, so prevention and early diagnosis is essential. Copyright © 2018 Sociedade Brasileira de Anestesiologia. Publicado por Elsevier Editora Ltda.

Production of a bioherbicide for biological control of weeds requires a series of steps, from selection of a suitable microbial strain to final formulation. Thus, this study aimed to select fungi for production of secondary metabolites with herbicidal activity using biological resources of the Brazilian Pampa biome. Phytopathogenic fungi were isolated from infected tissues of weeds in the Pampa biome. A liquid synthetic culture medium was used for production of metabolites. The phytotoxicity of fungal metabolites was assessed via biological tests using the plant Cucumis sativus L., and the most promising strain was identified by molecular analysis. Thirty-nine fungi were isolated, and 28 presented some phytotoxic symptoms against the target plant. Fungus VP51 belonging to the genus Diaporthe showed the most pronounced herbicidal activity. The Brazilian Pampa biome is a potential resource for the development of new and sustainable chemical compounds for modern agriculture. Copyright © 2016 Sociedade Brasileira de Microbiologia.

Dong, Yuwei; Zhang, Yanqiu; Tu, Baojun

Ammonia-oxidizing bacteria were immobilized by polyvinyl alcohol (PVA) and sodium alginate. The immobilization conditions and ammonia oxidation ability of the immobilized bacteria were investigated. The following immobilization conditions were observed to be optimal: PVA, 12%; sodium alginate, 1.1%; calcium chloride, 1.0%; inoculum concentration, 1.3 immobilized balls/mL of immobilized medium; pH, 10; and temperature, 30°C. The immobilized ammonia-oxidizing bacteria exhibited strong ammonia oxidation ability even after being recycled four times. The ammonia nitrogen removal rate of the immobilized ammonia-oxidizing bacteria reached 90.30% under the optimal immobilization conditions. When compared with ammonia-oxidizing bacteria immobilized by sodium alginate alone, the bacteria immobilized by PVA and sodium alginate were superior with respect to pH resistance, the number of reuses, material cost, heat resistance, and ammonia oxidation ability.

Cytrynowicz, R

2000-01-01

In 1944, 73 women nurses were sent to Italy to serve in World War II as part of the Forca Expedicionaria Brasileira (FEB) and the Brazilian Air Force (FAB). This event is studied in the context of the Vargas policies to mobilize the civilian population and to construct an internal front. The Estado Novo and the war constituted an important period in the affirmation of 'modern' nursing, as it was likewise vital in affirming nursing as a professional model for middle-class women. Nursing allowed the State to shape one of its most persuasive images: that of motherland. This image brought maternal care right to the battle front, helping make the war a collective experience that should bring together all men and women--all Brazilians--regardless of social stratum. The drive to forge a domestic front combined war mobilization efforts with efforts to win the middle classes over to the Estado Novo.

To analyze the association between parental tobacco consumption and the prevalence of psychomotor development disorders in children between 6 and 22 months of age. One hundred and nine mothers, fathers, and their babies participated in the study. The sociodemographic and clinical conditions were assessed using questionnaires. Tobacco consumption was assessed using the Fagerström Test for Nicotine Dependence (FTND). Child development was evaluated using the Scale of Psychomotor Development in Early Childhood. There was a significant negative correlation between the father's morning smoking (FTND) and the child's language development quotient; r=-0.41, p=0.005, r(2)=0.15. The children of mothers without nicotine dependence had a higher mean language development quotient than children of mothers with nicotine dependence; F(1, 107)=5.51, p=0.021, ηp(2)=0.05. Parental smoking appears to have a detrimental effect on child development. Copyright © 2015 Sociedade Brasileira de Pediatria. Published by Elsevier Editora Ltda. All rights reserved.

Salivary anti-PGL-1 IgM may indicate active transmission of Mycobacterium leprae among young people under 16 years of age.

Macedo, Alexandre Casimiro de; Cunha, José Evandro; Yaochite, Juliana Navarro Ueda; Tavares, Clodis Maria; Nagao-Dias, Aparecida Tiemi

Considering that the main route of Mycobacterium leprae transmission is the upper respiratory tract, detection of salivary antibodies can be a useful tool for diagnosing early infection. The study aimed to analyze salivary anti-PGL-1 IgA and IgM antibodies in 169 children aged 4-16 years old, who lived nearby or inside the house of multibacillary or paucibacillary leprosy patients in two endemic cities in Alagoas State - Brazil. Salivary anti-PGL-1 antibodies were quantified by modified ELISA method. The frequency of contact and clinical form of the index case were significantly associated with salivary antibody levels. High frequency of IgM positivity strongly suggests active transmission of M. leprae in these communities. We suggest in the present work that salivary anti-PGL IgA and IgM are important biomarkers to be used for identifying communities with probable active transmission of M. leprae.

2016-12-01

Fresh produce is a generalized term for a group of farm-produced crops, including fruits and vegetables. Organic agriculture has been on the rise and attracting the attention of the food production sector, since it uses eco-agricultural principles that are ostensibly environmentally-friendly and provides products potentially free from the residues of agrochemicals. Organic farming practices such as the use of animal manure can however increase the risk of contamination by enteric pathogenic microorganisms and may consequently pose health risks. A number of scientific studies conducted in different countries have compared the microbiological quality of produce samples from organic and conventional production and results are contradictory. While some have reported greater microbial counts in fresh produce from organic production, other studies do not. This manuscript provides a brief review of the current knowledge and summarizes data on the occurrence of pathogenic microorganisms in vegetables from organic production.

To describe the challenges faced by families caring for children with autism spectrum disorder (ASD) in Brazil and the coping strategies employed. Systematic review of articles published until September of 2013, without language restrictions, using quality appraisal (AMSTAR and CASP/Oxford instruments). The literature shows parental emotional overload as one of the main challenges faced by families, especially mothers. The main stressors were diagnostic postponement, difficulty dealing with the diagnosis and associated symptoms, and poor access to health services and social support. The predominant coping strategies found included information exchange between affected families and integrated healthcare network for patient and family support. ASD exerts strong influence on family dynamics, resulting in caregiver overload, especially in mothers. The Brazilian Unified Health System needs to provide comprehensive, continuous, and coordinated care to strengthen the patient-family dyad and promote the full development and societal inclusion of children with ASD.

The hemoflagellate protozoan, Trypanosoma cruzi, mainly transmitted by triatomine insects through blood transfusion or from mother-to-child, causes Chagas' disease. This is a serious parasitic disease that occurs in Latin America, with considerable social and economic impact. Nifurtimox and benznidazole, drugs indicated for treating infected persons, are effective in the acute phase, but poorly effective during the chronic phase. Therefore, it is extremely urgent to find innovative chemotherapeutic agents and/or effective vaccines. Since piplartine has several biological activities, including trypanocidal activity, the present study aimed to evaluate it on two T. cruzi strains proteome. Considerable changes in the expression of some important enzymes involved in parasite protection against oxidative stress, such as tryparedoxin peroxidase (TXNPx) and methionine sulfoxide reductase (MSR) was observed in both strains. These findings suggest that blocking the expression of the two enzymes could be potential targets for therapeutic studies. Copyright © 2018 Sociedade Brasileira de Infectologia.

Passos-Castilho, Ana Maria; Reinaldo, Mônica Renata; Sena, Anne de; Granato, Celso F H

Brazil is a non-endemic country for hepatitis E virus (HEV) infection with seroprevalence from 1% to 4% in blood donors and the general population. However, data on seroprevalence of HEV in the country are still limited. This study evaluated the prevalence of past or present HEV infection in a group of blood donors representative of the general population of the city of Sao Paulo, Southeastern Brazil. Serum samples from 500 blood donors were tested from July to September 2014 by serological and molecular methods. Anti-HEV IgG antibodies were detected in 49 (9.8%) subjects and categorized age groups revealed an age-dependent increase of HEV seroprevalence. Among the anti-HEV IgG positive subjects, only 1 had anti-HEV IgM while none tested positive for HEV-RNA. The present data demonstrate a higher seroprevalence of anti-HEV IgG than previously reported in the region. Copyright © 2017 Sociedade Brasileira de Infectologia. Published by Elsevier Editora Ltda.

Colistin resistance involving Gram-negative bacilli infections is a challenge for health institutions around of the world. Carbapenem-resistance among these isolates makes colistin the last therapeutic option for this treatment. Colistin resistance among Enterobacteriaceae, Acinetobacter spp., and Pseudomonas spp. was evaluated between 2010 and 2014 years, at Hospital das Clínicas, São Paulo, Brazil. Over five years 1346 (4.0%) colistin resistant Gram-negative bacilli were evaluated. Enterobacteriaceae was the most frequent (86.1%) pathogen isolated, followed by Acinetobacter spp. (7.6%), and Pseudomonas spp. (6.3%). By temporal analysis there was a trend for an increase of colistin resistance among Enterobacteriaceae, but not among non-fermentative isolates. Among 1346 colistin resistant isolates, carbapenem susceptibility was observed in 21.5%. Colistin resistance in our hospital has been alarmingly increased among Klebsiella pneumoniae isolates in both KPC positive and negative, thus becoming a therapeutic problem.

Strain RT1 was isolated from root nodules of Lens culinaris (a lentil) and characterized as Rhizobium etli (a Gram-negative soil-borne bacterium) by 16S rDNA sequencing and phylogenetic analysis. The signaling molecules produced by R. etli (RT1) were detected and identified by high-performance liquid chromatography coupled with mass spectrometry. The most abundant and biologically active N-acyl homoserine lactone molecules (3-oxo-C 8 -HSL and 3-OH-C 14 -HSL) were detected in the ethyl acetate extract of RT1. The biological role of 3-oxo-C 8 -HSL was evaluated in RT1. Bacterial motility and biofilm formation were affected or modified on increasing concentrations of 3-oxo-C 8 -HSL. Results confirmed the existence of cell communication in RT1 mediated by 3-oxo-C 8 -HSL, and positive correlations were found among quorum sensing, motility and biofilm formation in RT1.

2018-01-16

Eight faculties in South Africa offer undergraduate physiotherapy training with gross anatomy included as a basis for clinical practice. Little information exists about anatomy education for this student body. A 42-question peer-reviewed survey was distributed to physiotherapy gross anatomy course coordinators in all the eight faculties. Seven coordinators from six (75%) of the universities responded. Two respondents' data from the same university were pooled. Collected data show that staff qualifications and experience varied widely and high to average staff to student ratios exist between faculties. Direct anatomy teaching duration was 12.3 (SD ±5.2) weeks per semester. Total number of weeks in courses per faculty was 27.6 (SD ±5.7) varying widely between institutions. Calculable direct contact anatomy hours ranged between 100 and 308 with a mean of 207.6 (SD ±78.1). Direct contact hours in lectures averaged 3.9 (SD ±1.6) per week and the average direct contact hours in practical sessions were 3.5 (SD ±1.8) per week. Dissection, prosection, plastinated models, surface anatomy, and e-learning were available across faculties. Ancillary modalities such as vertical integration and inter-professional learning were in use. All faculties had multiple-choice questions, spot tests, and short examination questions. Half had viva-voce examinations and one had additional long questions assessment. Students evaluated teaching performance in five faculties. Four faculties were reviewing anatomy programs to consider implementing changes to anatomy curriculum or pedagogy. The findings highlighted disparity between programs and also identified the need for specific guidelines to develop a unified South African gross anatomy course for physiotherapy students.

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.

Maternal diet affects offspring DNA methylation in animal models, but evidence from humans is limited. We investigated the extent to which gestational intake of methyl donor nutrients affects global DNA methylation in maternal and umbilical cord blood. Among mother-infant pairs in Project Viva, a folate-replete US population, we estimated maternal intakes of vitamin B12, betaine, choline, folate, cadmium, zinc and iron periconceptionally and during the second trimester. We examined associations of these nutrients with DNA methylation, measured as %5-methyl cytosines (%5mC) in Long Interspersed Nuclear Element-1 (LINE-1), in first trimester (n = 830) and second trimester (n = 671) maternal blood and in cord blood at delivery (n = 516). Cord blood methylation was higher for male than female infants {mean [standard deviation (SD)] 84.8 [0.6] vs. 84.4 [0.7]%}. In the multivariable-adjusted model, maternal intake of methyl donor nutrients periconceptionally and during the second trimester of pregnancy was not positively associated with first trimester, second trimester or cord blood LINE-1 methylation. Periconceptional betaine intake was inversely associated with cord blood methylation [regression coefficient = -0.08% (95% confidence interval (CI): -0.14,-0.01)] but this association was attenuated after adjustment for dietary cadmium, which itself was directly associated with first trimester methylation and inversely associated with cord blood methylation. We also found an inverse association between periconceptional choline [-0.10%, 95% CI: -0.17,-0.03 for each SD (~63 mg/day)] and cord blood methylation in males only. In this folate-replete population, we did not find positive associations between intake of methyl donor nutrients during pregnancy and DNA methylation overall, but among males, higher early pregnancy intakes of choline were associated with lower cord blood methylation.

An objective of the study was to work out a complex program of gait restoration in patients with stroke using robot-driven mechanized gait trainers. The study included patients in the acute period of stroke (the mean age 59+/-10,4 years) who were not able to walk without assistance; 53 patients of the main group and 25 patients of the control group. The mean interval from the disease onset to the beginning of gait retraining sessions with mechanized gait trainers was 14+/-1,6 days depending on the adequacy of functional probes. The restoration program included everyday 30 minute sessions of exercise therapy. Patients of the main group received 20 min sessions using mechanized gait trainers Motomed Viva 2 and Gait Trainer 1 (GT1) with continuous monitoring of blood pressure and cardiac beat frequency. The number of sessions with GT1 was from 5 to 12, mean 7+/-1 sessions. After the complex restoration treatment, significant positive changes on scales of standing balance, functional categories of gait, Berg, Barthel (p< or =0.01) were observed in patients of the main group compared to controls. All patients of the main group became able to walk with a support or independently. The significant decrease (p< or =0.05) of a number of patients with disorders of proprioceptive sensitivity (from 37,7 to 9,4%) and with ataxia of the low extremities (from 37 to 11,3%) was observed in the main group, while no changes were seen in the control group. It has been concluded that the complex use of reflex kinesitherapy and robot-driven mechanotherapy in patients in the acute period of stroke allows to increase the functional activity and the level of self-service already prior to the discharge from hospital.

From Churches to Pavements: Urban Geology and Paleontology in Algarve

2015-04-01

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

Background Prenatal air pollution exposure inhibits fetal growth, but implications for postnatal growth are unknown. Methods We assessed weights and lengths of US infants in the Project Viva cohort at birth and 6 months. We estimated third-trimester residential air pollution exposures using spatiotemporal models. We estimated neighborhood traffic density and roadway proximity at birth address using geographic information systems. We performed linear and logistic regression adjusted for sociodemographic variables, fetal growth, and gestational age at birth. Results Mean birth weight-for-gestational age z-score (fetal growth) was 0.17 (SD = 0.97; n=2,114), 0-6 month weight-for-length gain was 0.23 z-units (SD = 1.11; n=689), and 17% had weight-for-length ≥95th percentile at 6 months of age. Infants exposed to the highest (vs. lowest) quartile of neighborhood traffic density had lower fetal growth (−0.13 units [95% confidence interval (CI) = −0.25 to −0.01]), more rapid 0-6 month weight-for-length gain (0.25 units [95% CI = 0.01 to 0.49]), and higher odds of weight-for-length ≥95th percentile at 6 months (1.84 [95% CI = 1.11 to 3.05]). Neighborhood traffic density was additionally associated with an infant being in both the lowest quartile of fetal growth and highest quartile of 0-6 month weight-for-length gain (Q4 vs. Q1, OR = 3.01 [95% CI = 1.08 to 8.44]). Roadway proximity and third-trimester black carbon exposure were similarly associated with growth outcomes. For third-trimester PM2.5, effect estimates were in the same direction, but smaller and imprecise. Conclusions Infants exposed to higher traffic-related pollution in early life may exhibit more rapid postnatal weight gain in addition to reduced fetal growth. PMID:25437317

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.

Glucose dysregulation in pregnancy may affect maternal depressive symptoms during the prenatal and postpartum periods via both physiologic and psychological pathways. During mid-pregnancy, a combination of 50-g 1-h non-fasting glucose challenge test (GCT) and 100-g 3-h fasting oral glucose tolerance test was used to determine pregnancy glycaemic status among women participating in Project Viva: normal glucose tolerance (NGT), isolated hyperglycaemia (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 odds 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. A total of 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 odds ratio (OR) per standard deviation (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% confidence interval (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 glycaemic status were significantly associated with elevated postpartum depressive symptoms. Pregnancy hyperglycaemia was cross-sectionally associated with higher risk of prenatal depressive symptoms, but not with postpartum depressive symptoms. © 2015 John Wiley & Sons Ltd.

Previous studies have shown that early liking, early consumption, and maternal consumption of fruits and vegetables (F&V) each predict children's F&V consumption, but no one has examined the independent contributions of these three correlated factors. We aim to examine the extent to which each of these 3 factors is associated with F&V consumption in mid-childhood after accounting for the other 2 in the analysis. We analyzed data from 901 mother-child dyads from Project Viva, a prospective pre-birth cohort study. Mothers reported their child's early liking and consumption of F&V at age 2 years and later consumption at mid-childhood (median age 7.7 years). They also reported their own consumption of F&V at 6 months postpartum. We used multivariable linear regression models to examine the independent associations of these 3 factors with mid-childhood consumption, adjusting for socio-demographic, pregnancy, and child confounders. At 2 years, 53% of the mothers strongly agreed that their child liked fruit and 25% strongly agreed that their child liked vegetables. F&V consumption was 2.5 (1.3) and 1.8 (1.1) times/d at age 2 y and 1.5 (1.1) and 1.3 (0.8) times/d in mid-childhood. Maternal F&V consumption was 1.4 (1.1) and 1.5 (1.0) times/d, respectively. Children's early consumption played the most predominant role. For every 1 time/d increment in children's early consumption of F&V, mid-childhood consumption was higher by 0.25 (95% confidence interval [CI]: 0.19, 0.30) times/d for fruits and 0.21 (95% CI: 0.16, 0.26) times/d for vegetables, adjusted for confounders plus the other 2 exposures. In conclusion, children's early F&V consumption has the most significant influence on children's later consumption. Published by Elsevier Ltd.

Perfluoroalkyl substances (PFASs) are synthetic chemicals that may persist in the environment and in humans. There is a possible association between early-life PFAS exposure and metabolic dysfunction in later life, but data are limited. We studied 665 mother-child pairs in Project Viva, a Boston, Massachusetts-area cohort recruited 1999-2002. We quantified concentrations of PFASs [perfluorooctanoate (PFOA), perfluorooctane sulfonate (PFOS), perfluorononanoate (PFNA), perfluorohexane sulfonate (PFHxS), and perfluorodecanoate (PFDeA)] in maternal plasma collected at the first prenatal visit (median, 9.6 weeks gestation) and in child plasma from the mid-childhood research visit (median, 7.7 years). We assessed leptin, adiponectin, and homeostatic model assessment of insulin resistance (HOMA-IR) in mid-childhood. We fit covariate-adjusted linear regression models and conducted stratified analyses by child sex. Children with higher PFAS concentrations had lower HOMA-IR [e.g., -10.1% (95% CI: -17.3, -2.3) per interquartile range increment in PFOA]. This inverse association between child PFAS and HOMA-IR was more pronounced in females [e.g., PFOA: -15.6% (95% CI: -25.4, -4.6) vs. -6.1% (95% CI: -16.2, 5.2) for males]. Child PFAS plasma concentrations were not associated with leptin or adiponectin. Prenatal PFAS plasma concentrations were not associated with leptin, adiponectin, or HOMA-IR in offspring. We found no evidence for an adverse effect of early-life PFAS exposure on metabolic function in mid-childhood. In fact, children with higher PFAS concentrations had lower insulin resistance.

This inverse association between child PFAS and HOMA-IR was more pronounced in females [e.g., PFOA: –15.6% (95% CI: –25.4, –4.6) vs. –6.1% (95% CI: –16.2, 5.2) for males]. Child PFAS plasma concentrations were not associated with leptin or adiponectin. Prenatal PFAS plasma concentrations were not associated with leptin, adiponectin, or HOMA-IR in offspring. Conclusions: We found no evidence for an adverse effect of early-life PFAS exposure on metabolic function in mid-childhood. In fact, children with higher PFAS concentrations had lower insulin resistance.

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.

Background: We examined associations of material hardship with prepregnancy body mass index (BMI), gestational weight gain (GWG), and substantial postpartum weight retention (SPPWR; ≥5 kg at 1 year). Methods: We studied 2128 women in Project Viva, a Boston-area cohort with recruitment during1999–2002. At recruitment, women reported whether they experienced material hardship, defined as having ever received public assistance, welfare, or lacked basic necessities (food, rent, or medical care) during childhood, in adulthood before pregnancy, and/or in pregnancy. We used multivariable logistic models adjusted for age, race/ethnicity, and parity (and prepregnancy BMI for GWG and SPPWR) to examine associations of material hardship with the three weight-related outcomes (BMI, GWG, and SPPWR). Results: Mean age was 31.8 (standard deviation, 5.2) years; 66% of women were white, 16% were obese (prepregnancy BMI ≥30.0 kg/m2), 50% experienced excessive GWG, and 17% experienced SPPWR. Material hardship was most common during childhood (n=192, 9%), followed by adulthood (102, 5%), and pregnancy (41, 2%). Hardship in adulthood was associated with prepregnancy obesity (BMI ≥30 kg/m2 vs. 18.5 to <25.0 kg/m2), odds ratio ([OR] 2.35, 95% confidence interval [CI] 1.29, 4.31), but hardship in childhood was not (OR 1.26, 95% CI 0.80, 1.98). Hardship in childhood was associated with excess GWG (OR 1.45, 95% CI 0.99, 2.14), but hardship in adulthood or during pregnancy was not. We saw trends among hardship in each of the periods and associations with SPPWR, but all confidence intervals included the null. Conclusion: The timing of hardship exposure may differently influence weight before, during, and after pregnancy. PMID:25902486

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.

Asymmetries in mother-infant behaviour in Barbary macaques (Macaca sylvanus)

Spiezio, Caterina; Hopkins, William Donald

2018-01-01

Asymmetries in the maternal behaviour and anatomy might play an important role in the development of primate manual lateralization. In particular, early life asymmetries in mother’s and infant’s behaviour have been suggested to be associated with the development of the hand preference of the offspring. The aim of this study was to investigate the presence of behavioural asymmetries in different behavioural categories of mother-infant dyads of zoo-living Barbary macaques (Macaca sylvanus). The study subjects were 14 Barbary macaques involved in seven mother-infant dyads housed in Parco Natura Viva, Italy. For the mothers, bouts of hand preference for maternal cradling and infant retrieval were collected. For the infants, we focused on nipple preference and hand preference for clinging on mother ventrum. Moreover, we collected bouts of hand preference for food reaching in both groups. No significant group-level bias was found for any of the behavioural categories in either mothers or infants. However, at the individual level, six out of seven mothers showed a significant cradling bias, three toward the right hand and three toward the left hand. Moreover, all infants showed a significant nipple preference, six toward the mother’s right nipple, one toward the left nipple. Furthermore, a significant correlation was found between the infant nipple preference and their hand preference for food reaching, suggesting that maternal environment rather than behaviour might affect the development of hand preference in Old World monkeys. Our findings seem partially to add to previous literature on perceptual lateralization in different species of non-primate mammals, reporting a lateral bias in mother-infant interactions. Given the incongruences between our study and previous research in great apes and humans, our results seem to suggest possible phylogenetic differences in the lateralization of mothers and infants within the Primates order.

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.

Pakistani nationals that obtained foreign basic/additional medical/dental qualifications need to be registered with Pakistan Medical and Dental Council (PMDC) to serve in health delivery system after qualifying the National Examination Board (NEB) conducted by the outsourced universities. The aim was to analyse the results and the factors that influence the NEB examinations held for accreditation conducted by different universities from the year 2010 to 2015. The register based data was collected from the NEB section of PMDC for examinations conducted in the year 2010, 2013, 2014 and 2015. The format of the examination comprises three parts that include Step I, II based on written assessment composed of both multiple choice and subjective questions. Step III is designed for oral assessment, i.e., viva voce. All these examination were held in Islamabad conducted by the outsourced universities. The percentage of candidates that has passed all the examinations, Step I, II & III held by various universities varies across the universities. Further, the percentage of passed candidate remains low in Step I & II as compared to candidates passed in Step III. Overall the result of Step III shows a wide gradient that ranges from 50% to 98% among the different universities. Likewise, the lowest percentage of passing candidates in Step I and Step II remains 4% and 9% respectively as compared to 50% in Step III. There is a wide gradient in the results of NEB examination among universities due to lack of uniformity and standardization of assessment process. In addition, with regards to the approach of examination venue, the faced issues include lack of accessibility and cost effectiveness. The PMDC needs to institutionalize a robust and vigorous accreditation system equipped with inbuilt evaluation indicators that should steer to devise strategies to improve the accreditation process.

"Loss of breath" as a cause of postoperative hypoxia and bradycardia in children submitted to tonsillectomy.

PubMed

Moro, Eduardo Toshiyuki; Goulart, Alexandre Palmeira

2015-01-01

the "shortness of breath" or "breathing interruption" crisis can be considered a cause of hypoxia in childhood. It is characterized by the presence of a triggering factor followed by weeping and apnea in expiration accompanied by cyanosis or pallor. The sequence of events may include bradycardia, loss of consciousness, abnormal postural tone and even asystole. A review of the literature revealed only two reports of postoperative apnea caused by "shortness of breath". this article describes the case of a child with a history of "shortness of breath" undiagnosed before the adenotonsillectomy, but that represented the cause of episodes of hypoxemia and bradycardia in the postoperative period. the "shortness of breath" crisis should be considered as a possible cause of perioperative hypoxia in children, especially when there is a history suggestive of this problem. As some events may be accompanied by bradycardia, loss of consciousness, abnormal postural tone and even asystole, observation in a hospital setting should be considered.

[Satellite glial cells in sensory ganglia: its role in pain].

PubMed

Costa, Filipa Alexandra Leite; Moreira Neto, Fani Lourença

2015-01-01

Satellite glial cells in sensory ganglia are a recent subject of research in the field of pain and a possible therapeutic target in the future. Therefore, the aim of this study was to summarize some of the important physiological and morphological characteristics of these cells and gather the most relevant scientific evidence about its possible role in the development of chronic pain. In the sensory ganglia, each neuronal body is surrounded by satellite glial cells forming distinct functional units. This close relationship enables bidirectional communication via a paracrine signaling between those two cell types. There is a growing body of evidence that glial satellite cells undergo structural and biochemical changes after nerve injury, which influence neuronal excitability and consequently the development and/or maintenance of pain in different animal models of chronic pain. Satellite glial cells are important in the establishment of physiological pain, in addition to being a potential target for the development of new pain treatments.

The burn patient is a challenge for the anesthesiologist, undergoing several surgeries during admission, and requiring general anesthesia and muscle relaxation most of the times. They have respiratory system impairment and a response to muscle relaxants that differs from the healthy patient, thus proper monitoring and reversal is crucial. We analyzed sugammadex effectiveness and safety in this population. Prospectively descriptive study including four patients, all of them considered major burn patients, who underwent escharotomy with general anesthesia and neuromuscular relaxation. The main variable was the time for recovery of a TOF higher than 0.9 after the administration of sugammadex before extubation. Mean time of recovery from a TOF ratio higher than 0.9 following the administration of Sugammadex was of 4.95minutes 95% CI (3.25-6.64, p=.53); The reversion of neuromuscular relaxation with sugammadex appears to be effective and safe in the burn patient. More analytical, comparative studies, of larger populations would be necessary to confirm this data. Copyright © 2015 Sociedade Brasileira de Anestesiologia. Publicado por Elsevier Editora Ltda.

[Inadvertent injection of succinylcholine as an epidural test dose].

PubMed

Pourzitaki, Chryssa; Tsaousi, Georgia; Logotheti, Helena; Amaniti, Ekaterini

Epidural action of neuromuscular blocking agents could be explained under the light of their physicochemical characteristics and epidural space properties. In the literature there are few cases of accidental neuromuscular agent's epidural administration, manifesting mainly with neuromuscular blockade institution or fasciculations. We report a case of accidental succinylcholine administration as an epidural test dose, in a female patient undergoing scheduled laparotomy, under combined general and epidural anesthesia. Approximately 2min after the succinylcholine injection the patient complained for shortness of breath, while mild fasciculations appeared in her trunk and face, managed by immediate general anesthesia institution. With the exception of a relatively longer duration of neuromuscular blockade compared with intravenous administration, no neurological or cardiovascular sequelae or other symptoms of local or systemic toxicity were observed. Oral administration of diazepam seems to lessen the adverse effects from accidental epidural administration of succinylcholine. The meticulous and discriminative labeling of syringes, as well as keeping persistent cautions during all anesthesia procedures remains of crucial importance.

Antibacterial efficacy of nisin, bacteriophage P100 and sodium lactate against Listeria monocytogenes in ready-to-eat sliced pork ham.

PubMed

Figueiredo, Ana Cláudia L; Almeida, Rogeria C C

The effectiveness of bacteriophage P100, nisin and sodium lactate, individually and in combination, in inhibiting Listeria monocytogenes in ready-to-eat pork ham slices was assessed. The antimicrobials were applied to the surfaces of ready-to-eat pork ham slices, which were inoculated with a mixture of L. monocytogenes. Among the individual antimicrobial treatments, bacteriophage P100 was the most effective, decreasing L. monocytogenes to undetectable levels at zero and 72h post-infection. Sodium lactate was the least effective treatment. Treatment with nisin at zeroh significantly reduced initial cell density (p<0.05). However, this pattern was not observed at 72h of storage. A significant difference (p<0.05) existed between the results of separate bacteriophage and nisin treatments after refrigerated storage, but not immediately upon inoculation of the bacteria. The results showed that the use of bacteriophage P100 is the method of choice for the control of bacteria. Copyright © 2017 Sociedade Brasileira de Microbiologia. Published by Elsevier Editora Ltda.

The aim of this study was to compare the predictions of Framingham cardiovascular (CV) risk score (FRS) and the American College of Cardiology/American Heart Association (ACC/AHA) risk score in an HIV outpatient clinic in the city of Vitoria, Espirito Santo, Brazil. In a cross-sectional study 341 HIV infected patients over 40 years old consecutively recruited were interviewed. Cohen's kappa coefficient was used to assess agreement between the two algorithms. 61.3% were stratified as low risk by Framingham score, compared with 54% by ACC/AHA score (Spearman correlation 0.845; p<0.000). Only 26.1% were classified as cardiovascular high risk by Framingham compared to 46% by ACC/AHA score (Kappa=0.745; p<0.039). Only one out of eight patients had cardiovascular high risk by Framingham at the time of a myocardial infarction event registered up to five years before the study period. Both cardiovascular risk scores but especially Framingham underestimated high-risk patients in this HIV-infected population. Copyright © 2017 Sociedade Brasileira de Infectologia.

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

The production of KPC (Klebsiella pneumoniae carbapenemase) is the major mechanism of resistance to carbapenem agents in enterobacterias. In this context, forty KPC-producing Enterobacter spp. clinical isolates were studied. It was evaluated the activity of antimicrobial agents: polymyxin B, tigecycline, ertapenem, imipenem and meropenem, and was performed a comparison of the methodologies used to determine the susceptibility: broth microdilution, Etest ® (bioMérieux), Vitek 2 ® automated system (bioMérieux) and disc diffusion. It was calculated the minimum inhibitory concentration (MIC) for each antimicrobial and polymyxin B showed the lowest concentrations for broth microdilution. Errors also were calculated among the techniques, tigecycline and ertapenem were the antibiotics with the largest and the lower number of discrepancies, respectively. Moreover, Vitek 2 ® automated system was the method most similar compared to the broth microdilution. Therefore, is important to evaluate the performance of new methods in comparison to the reference method, broth microdilution. Copyright © 2017 Sociedade Brasileira de Microbiologia.

To review the screening, diagnosis, evaluation, and treatment of intoxication by alcohol and other drugs in children and adolescents in the emergency scenario. This was a narrative literature review. The detection of this problem in the emergency room can be a challenge, especially when its assessment is not standardized. The intentional and episodic use of large amounts of psychoactive substances by adolescents is a usual occurrence, and unintentional intoxication is more common in children younger than 12 years. The clinical picture in adolescents and children differs from that in adults and some particularities are important in the emergency scenario. After management of the acute condition, interventions targeting the adolescent at risk may be effective. The diagnosis and treatment of intoxication by alcohol and other drugs in adolescents and children in the emergency scenario requires a systematic evaluation of the use of these drugs. There are few specific treatments for intoxication, and the management comprehends support measures and management of related clinical complications.

Arbuscular mycorrhizal fungal communities in the rhizosphere of a continuous cropping soybean system at the seedling stage.

PubMed

Cui, Jiaqi; Bai, Li; Liu, Xiaorui; Jie, Weiguang; Cai, Baiyan

Arbuscular mycorrhizae (AM) fungi play a crucial role in the growth of soybean; however, the planting system employed is thought to have an effect on AM fungal communities in the rhizosphere. This study was performed to explore the influence of continuous soybean cropping on the diversity of Arbuscular mycorrhizal (AM) fungi, and to identify the dominant AM fungus during the seedling stage. Three soybean cultivars were planted under two and three years continuous cropping, respectively. The diversity of AM fungi in the rhizosphere soil at the seedling stage was subsequently analyzed using polymerase chain reaction (PCR)-denaturing gradient gel electrophoresis (DGGE). The results showed that an increase in cropping years improved the colonization rate of AM in all three soybean cultivars. Moreover, the dominant species were found to be Funneliformis mosseae and Glomus species. The results of cluster analysis further confirmed that the number of years of continuous cropping significantly affected the composition of rhizospheric AM fungal communities in different soybean cultivars.

Rosso, Fernando; Pineda, Juan C; Sanz, Ana M; Cedano, Jorge A; Caicedo, Luis A

Dengue fever is a vector-transmitted viral infection. Non-vectorial forms of transmission can occur through organ transplantation. We reviewed medical records of donors and recipients with suspected dengue in the first post-transplant week. We used serologic and molecular analysis to confirm the infection. Herein, we describe four cases of dengue virus transmission through solid organ transplantation. The recipients had positive serology and RT-PCR. Infection in donors was detected through serology. All cases presented with fever within the first week after transplantation. There were no fatal cases. After these cases, we implemented dengue screening with NS1 antigen detection in donors during dengue outbreaks, and no new cases were detected. In the literature review, additional cases had been published through August 2017. Transmission of Dengue virus can occur through organ donation. In endemic regions, it is important to suspect and screen for dengue in febrile and thrombocytopenic recipients in the postoperative period. Copyright © 2018 Sociedade Brasileira de Infectologia.

Hereditary angioedema is an autosomal dominant disease characterized by edema attacks with multiple organ involvement. It is caused by a quantitative or functional deficiency of the C1 inhibitor, which is a member of the serine protease inhibitor family. Hereditary angioedema is unknown to many health professionals and is therefore an underdiagnosed disease. The causes of death from hereditary angioedema include laryngeal edema with asphyxia. The estimated mortality rate in patients in whom the disease goes undetected and who are therefore incorrectly treated is 25-40%. In addition to edema of the glottis, hereditary angioedema often results in edema of the gastrointestinal tract, which can be incapacitating. Patients with hereditary angioedema may undergo unnecessary surgical interventions because the digestive tract can be the primary or only organ system involved, thus mimicking acute surgical abdomen. It is estimated that patients with hereditary angioedema experience some degree of disability 20-100 days per year. The Experts in Clinical Immunology and Allergy of the "Associação Brasileira de Alergia e Imunopatologia -ASBAI" developed these guidelines for the diagnosis, therapy, and management of hereditary angioedema.

Currently there is no agreement regarding which one is the most adequate anesthetic technique for the treatment of retinopathy of prematurity. Peribulbar block may reduce the incidence of oculocardiac reflex and postoperative apnea. The goal of this study was to report the outcomes of peribulbar block, when combined with general anesthesia, for the laser treatment for retinopathy of prematurity, in premature babies. A retrospective analysis of anesthetic records of all babies who underwent laser treatment for retinopathy of prematurity from January 2008 through December 2015 in a tertiary hospital was performed. During that period a total of six babies was submitted to laser treatment for retinopathy of prematurity, all under peribulbar block combined with general anesthesia. A single infratemporal injection of 0.15mL.kg -1 per eye ropivacaine 1% or 0.75% was performed. At the end of the procedure, all babies resumed spontaneous ventilation. No perioperative complications were reported. Peribulbar block was a safe anesthetic technique in our sample considered. Copyright © 2018 Sociedade Brasileira de Anestesiologia.

Background Quotations in Brazilian journals are mainly obtained from national articles (articles from Brazilian journals); thus, it is essential to determine how frequently these articles reference Brazilian journals. Objective This study sought to verify how frequently national papers are cited in the references of three Brazilian physical therapy journals. Method All references for articles published in Fisioterapia em Movimento, Fisioterapia e Pesquisa and Revista Brasileira de Fisioterapia between 2010 and 2012 were evaluated. In particular, the numbers of national articles and international articles (articles from international journals) cited in these references were determined. Results A total of 13,009 references cited by 456 articles were analyzed, and 2,924 (22.47%) of the cited works were national articles. There were no significant differences among the three examined years. A total of 36 (7.89%) articles did not cite national articles, whereas 65 (13.25%) articles cited more national articles than international articles. Conclusion On average, 22.47% of the works cited by the evaluated articles were national articles. No significant differences were detected among the three analyzed years. PMID:24675917

Effects of hurdle technology on Monascus ruber growth in green table olives: a response surface methodology approach.

PubMed

Cappato, Leandro P; Martins, Amanda M Dias; Ferreira, Elisa H R; Rosenthal, Amauri

An ascomycetes fungus was isolated from brine storage of green olives of the Arauco cultivar imported from Argentina and identified as Monascus ruber. The combined effects of different concentrations of sodium chloride (3.5-5.5%), sodium benzoate (0-0.1%), potassium sorbate (0-0.05%) and temperature (30-40°C) were investigated on the growth of M. ruber in the brine of stored table olives using a response surface methodology. A full 2 4 factorial design with three central points was first used in order to screen for the important factors (significant and marginally significant factors) and then a Face-Centered Central Composite Design was applied. Both preservatives prevented fungal spoilage, but potassium sorbate was the most efficient to control the fungi growth. The combined use of these preservatives did not show a synergistic effect. The results showed that the use of these salts may not be sufficient to prevent fungal spoilage and the greatest fungal growth was recorded at 30°C.

to determine the prevalence and to analyze factors associated with hookah use initiation among adolescents. This was a cross-sectional study, in which questionnaires were collected from 495 students attending public and private schools of the urban area of the city of Várzea Grande, in the state of Mato Grosso, Brazil. Data were analyzed through descriptive, bivariate, and multiple Poisson regression analyses. A total of 19.7% students had tried a hookah. The use of hookah was associated with the final period of adolescence [PR=6.54 (2.79, 15.32)]; enrollment in private schools [PR=2.23 (1.73, 2.88)]; and presence of work activities [PR=1.80 (1.17, 2.78)]. The proportion of adolescents that had tried a hookah was high. The influence of age, work activities, and class period on smoking initiation using the hookah was observed. Preventive measures encompassing all forms of tobacco smoking should be targeted at adolescents in the school environment, aiming at tobacco use control.

The antagonistic potential of Trichoderma strains was assayed by studying the effect of their culture filtrate on the radial growth of Sclerotium rolfsii, the causal agent of chickpea collar rot. Trichoderma harzianum-1432 (42.2%) and Trichoderma atroviride (40.3%) were found to be strong antagonists. To enhance their antagonistic potential, mutagenesis of these two selected strains was performed. Two mutants, Th-m1 and T. atroviride m1, were found to be more effective than their parent strains. The enzymatic activities of the selected parent and mutant strains were assayed, and although both mutants were found to have enhanced enzymatic activities compared to their respective parent strains, Th-m1 possessed the maximum cellulase (5.69U/mL) and β-1,3-glucanase activity (61.9U/mL). Th-m1 also showed high competitive saprophytic ability (CSA) among all of the selected parent and mutant strains, and during field experiments, Th-m1 was found to successfully possess enhanced disease control (82.9%).

The aim of this study was to identify the perceptions of blood donors and recipients regarding the act of donating blood. This descriptive study with a survey design focuses on subjective and cultural aspects. Twenty donors and 20 recipients in the blood bank at the time of data collection participated in the study. Interviews were analyzed according to deductive thematic analysis. Two themes emerged - perceptions of donors and perceptions of recipients. Both groups saw the act of donating blood as something positive, though donors associated their reports with the experiences of people close to them who needed blood transfusions, while the recipients associated donations with the maintenance of their lives as, for them, a blood transfusion was a necessary medical treatment. Perceptions regarding blood donations are culturally constructed, as the participants associated knowledge acquired in the social world with moral issues and their life experiences. Hence, in addition to helping others, these individuals feel socially and morally rewarded. Copyright © 2016 Associação Brasileira de Hematologia, Hemoterapia e Terapia Celular.

The biodiversity and evolution of the microbial community in açai fruits (AF) between three geographical origins and two spontaneous decay conditions were examined by applying culture-independent methods. Culture-independent methods based on 16S rRNA from fifteen samples revealed that Proteobacteria, Firmicutes, Actinobacteria, Bacteroidetes and Acidobacteria were the most abundant phyla. At the genus level, Massilia (taxon with more than 50% of the sequences remaining constant during the 30h of decay), Pantoea, Naxibacter, Enterobacter, Raoultella and Klebsiella were identified, forming the carposphere bacterial microbiota of AF. AF is fibre-rich and Massilia bacteria could find a large quantity of substrate for its growth through cellulase production. Beta diversity showed that the quality parameters of AF (pH, soluble solids, titratable acidity and lipids) and elemental analysis (C, N, H and C/N ratio) were unable to drive microbial patterns in AF. This research offers new insight into the indigenous bacterial community composition on AF as a function of spontaneous postharvest decay. Copyright © 2018 Sociedade Brasileira de Microbiologia.

The increased use of epidural analgesia with catheter leads to the need to demonstrate the safety of this method and know the incidence of catheter colonization, inserted postoperatively for epidural analgesia, and the bacteria responsible for this colonization. From November 2011 to April 2012, patients electively operated and maintained under epidural catheter for postoperative analgesia were evaluated. The catheter tip was collected for semiquantitative and qualitative microbiological analysis. Of 68 cultured catheters, six tips (8.8%) had positive cultures. No patient had superficial or deep infection. The mean duration of catheter use was 43.45hours (18-118) (p=0.0894). The type of surgery (contaminated or uncontaminated), physical status of patients, and surgical time showed no relation with the colonization of catheters. Microorganisms isolated from the catheter tip were Staphylococcus aureus, Pseudomonas aeruginosa and Sphingomonas paucimobilis. Postoperative epidural catheter analgesia, under this study conditions, was found to be low risk for bacterial colonization in patients at surgical wards.

Aspirin-exacerbated respiratory disease (AERD) consists of a classic tetrad: moderate/severe asthma, chronic rhinosinusitis, nasal polyps, and intolerance to aspirin or other nonsteroidal anti-inflammatory drugs. Clinical control with drugs, surgery, and desensitization are treatment options. To evaluate the efficacy and tolerability of aspirin desensitization in patients with AERD. Periodic symptom assessment and endoscopy in patients with AERD undergoing surgery who were desensitized. Seventeen patients were desensitized. Eight patients completed the desensitization and were followed for a minimum of a one-year period (mean 3.1 years). These patients showed improvement in all symptoms. Moreover, surgical reassessment was not indicated in any of these patients and there was a decrease in costs with medication and procedures. Eight patients did not complete desensitization, mainly due to procedure intolerance and uncontrolled asthma, whereas another patient was lost to follow-up. Aspirin desensitization, when tolerated, was effective in patients with AERD and with poor clinical/surgical response.

this systematic review aims to explore and describe the studies that have as a primary outcome the identification of mothers' perception of the nutritional status of their children. the PubMed, Embase, LILACS, and SciELO databases were researched, regardless of language or publication date. The terms used for the search, with its variants, were: Nutritional Status, Perception, Mother, Maternal, Parents, Parental. after screening of 167 articles, 41 were selected for full text reading, of which 17 were included in the review and involved the evaluation of the perception of mothers on the nutritional status of 57,700 children and adolescents. The methodological quality of the studies ranged from low to excellent. The proportion of mothers who inadequately perceived the nutritional status of their children was high, and was the most common underestimation for children with overweight or obesity. despite the increasing prevalence of obesity in pediatric age, mothers have difficulty in properly perceiving the nutritional status of their children, which may compromise referral to treatment programs.

To analyze the prevalence of excess weight and low height, and identify associated factors among children younger than five years. Cross-census study. A total of 1,640 children from two municipalities in Piauí, Brazil were included. The prevalence of low height was 10.9% (95% CI: 9.3 to 12.4), inversely associated with mother's younger age and low level of education, lower socioeconomic status, mothers who had fewer than six prenatal consultations, and households that had more than one child younger than 5 years. Excess weight prevalence was 19.1% (95% CI: 17.2 to 21.0), and remained inversely associated with lower maternal age, low maternal education, and cesarean delivery. Stunting was greater in children aged between 12 and 23 months, while excess weight decreased with age. It is noteworthy that the stunting rate, although decreasing, is still high, while the prevalence of excess weight, even in this very poor area, already exceeds the expected percentage for a population with better socioeconomic level.

Moro, Eduardo Toshiyuki; Goulart, Alexandre Palmeira

2015-01-01

The "shortness of breath" or "breathing interruption" crisis can be considered a cause of hypoxia in childhood. It is characterized by the presence of a triggering factor followed by weeping and apnea in expiration accompanied by cyanosis or pallor. The sequence of events may include bradycardia, loss of consciousness, abnormal postural toneand even asystole. A review of the literature revealed only two reports of postoperative apneacaused by "shortness of breath". This article describes the case of a child with a history of "shortness of breath" undiagnosed before the adenotonsillectomy, but that represented the cause of episodes of hypoxemia and bradycardia in the postoperative period. the "shortness of breath" crisis should be considered as a possible cause of perioperative hypoxia in children, especially when there is a history suggestive of this problem. As some events may be accompanied by bradycardia, loss of consciousness, abnormal postural tone and even asystole, observation in a hospital setting should be considered.

PubMed

Mason, Chawla LaToya

This case report describes the rare occurrence of paraplegia caused by conversion disorder in a woman who received general anesthesia for breast surgery. A 46-year-old healthy woman received general anesthesia for excision of a left breast fibroepithelial lesion. In the post-anesthesia care unit, she reported bilateral loss of both sensation and motor function below the knees. Physical signs and symptoms did not correlate with any anatomical or neurological patterns; imaging revealed no abnormalities. Psychiatric consultation was performed wherein familial stressor circumstances were identified, leading to diagnosis and management of conversion disorder. Conversion disorder is characterized by alteration of physical function due to expression of an underlying psychological ailment. Its diagnosis requires thorough evaluation including appropriate workup to exclude organic causes. The meshing together of anesthesiology and psychiatry - as demonstrated by this case report - offers an opportunity to highlight important information pertaining to the definition, diagnosis, and management of conversion disorder as it may be encountered in the postanesthesia recovery period.

to evaluate associations between morphometric variables, cervical circumference (CC), and abdominal circumference (AC) with the presence of nocturnal desaturation in children and adolescents with sickle-cell anemia. all patients were submitted to baseline polysomnography, oral cavity measurements (maxillary intermolar distance, mandibular intermolar distance, and overjet), and CC and AC measurements. a total of 85 patients were evaluated. A positive correlation was observed between the height/age Z-score and CC measurement (r = 0.233, p = 0.031). The presence of nocturnal desaturation was associated with CC (59.2± 9.3 vs. 67.5 ± 10.7, p = 0.006) and AC measurements (27.0 ± 2.0 vs. 29.0± 2.1, p = 0.028). There was a negative correlation between desaturation and maxillary intermolar distance (r = -0.365, p = 0.001) and mandibular intermolar distance (r = -0.233, p = 0.037). the morphometric variables of CC and AC may contribute to raise suspicion of nocturnal desaturation in children and adolescents with sickle-cell anemia.

2016-01-01

Thirty-six isolates of psittacid herpesvirus (PsHV), obtained from 12 different species of psittacids in Brazil, were genotypically characterized by restriction fragment length polymorphism (RFLP) analysis and PCR amplification. RFLP analysis with the PstI enzyme revealed four distinct restriction patterns (A1, X, W and Y), of which only A1 (corresponding to PsHV-1) had previously been described. To study PCR amplification patterns, six pairs of primers were used. Using this method, six variants were identified, of which, variants 10, 8, and 9 (in this order) were most prevalent, followed by variants 1, 4, and 5. It was not possible to correlate the PCR and RFLP patterns. Twenty-nine of the 36 isolates were shown to contain a 419bp fragment of the UL16 gene, displaying high similarity to the PsHV-1 sequences available in GenBank. Comparison of the results with the literature data suggests that the 36 Brazilian isolates from this study belong to genotype 1 and serotype 1. Copyright © 2015 Sociedade Brasileira de Microbiologia.

2016-01-01

The ultrasound guidance in regional anesthesia ensures the visualization of needle placement and the spread of Local Anesthetics. Over the past few years there was a substantial interest in determining the Minimum Effective Anesthetic Volume necessary to accomplish surgical anesthesia. The precise and real-time visualization of Local Anesthetics spread under ultrasound guidance block may represent the best requisite for reducing Local Anesthetics dose and Local Anesthetics-related effects. We will report a series of studies that have demonstrated the efficacy of ultrasound guidance blocks to reduce Local Anesthetics and obtain surgical anesthesia as compared to block performed under blind or electrical nerve stimulation technique. Unfortunately, the results of studies are widely divergent and not seem to indicate a dose considered effective, for each block, in a definitive way; but it is true that, through the use of ultrasound guidance, it is possible to reduce the dose of anesthetic in the performance of anesthetic blocks.

2016-01-01

Although the consumption of fresh and minimally processed vegetables is considered healthy, outbreaks related to the contamination of these products are frequently reported. Among the food-borne pathogens that contaminate vegetables is Listeria monocytogenes, a ubiquitous organism that exhibits the ability to survive and multiply at refrigerated temperatures. This study aimed to evaluate the occurrence of L. monocytogenes in vegetables as well as the antimicrobial resistance of isolates. The results showed that 3.03% of samples were contaminated with L. monocytogenes, comprising 2.22% of raw vegetables and 5.56% of ready-to-eat vegetables. Multiplex PCR confirmed the virulence potential of the isolates. Antimicrobial resistance profiling showed that 50% of the isolates were susceptible to the antibiotics used. The resistance of one isolate to penicillin G, a commonly employed therapeutic agent, and the presence of serotype 4b, a serotype commonly associated with food-borne outbreaks, could be potential health hazards for consumers.

Mirhosseini, Seyed Ali; Fooladi, Abbas Ali Imani; Amani, Jafar; Sedighian, Hamid

Food-borne diseases, caused by the pathogenic bacteria, are highly prevalent in the world. Salmonella is one of the most important bacterial genera responsible for this. Salmonella Enteritidis (SE) is one of the non-typhoid Salmonellae that can be transmitted to human from poultry products, water, and contaminated food. In recent years, new and rapid detection methods such as enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR) have been developed. In this study, recombinant FliC (rFliC) was produced to be used as an antigen. The immunization was conducted in mice with the purified recombinant FliC (rFliC). The mice were subcutaneously immunized with rFliC and elicited significant rFliC specific serum IgG antibodies. An indirect ELISA system was established for the detection of Salmonella Enteritidis. Our results confirmed that the recombinant flagellin can be one of the excellent indicators for the detection of Salmonella Enteritidis. Copyright © 2017 Sociedade Brasileira de Microbiologia.

Management of abdominal compartment syndrome after transurethral resection of the prostate.

PubMed

Gaut, Megan M; Ortiz, Jaime

2015-01-01

Acute abdominal compartment syndrome is most commonly associated with blunt abdominal trauma, although it has been seen after ruptured abdominal aortic aneurysm, liver transplantation, pancreatitis, and massive volume resuscitation. Acute abdominal compartment syndrome develops once the intra-abdominal pressure increases to 20-25 mmHg and is characterized by an increase in airway pressures, inadequate ventilation and oxygenation, altered renal function, and hemodynamic instability. This case report details the development of acute abdominal compartment syndrome during transurethral resection of the prostate with extra- and intraperitoneal bladder rupture under general anesthesia. The first signs of acute abdominal compartment syndrome in this patient were high peak airway pressures and difficulty delivering tidal volumes. Management of the compartment syndrome included re-intubation, emergent exploratory laparotomy, and drainage of irrigation fluid. Difficulty with ventilation should alert the anesthesiologist to consider abdominal compartment syndrome high in the list of differential diagnoses during any endoscopic bladder or bowel case.

Introduce a program for the management of scientific research in a General Hospital employing the business management tools Lean Six Sigma and PMBOK for project management in this area. The Lean Six Sigma methodology was used to improve the management of the institution's scientific research through a specific tool (DMAIC) for identification, implementation and posterior analysis based on PMBOK practices of the solutions found. We present our solutions for the management of institutional research projects at the Sociedade Beneficente Israelita Brasileira Albert Einstein. The solutions were classified into four headings: people, processes, systems and organizational culture. A preliminary analysis of these solutions showed them to be completely or partially compliant to the processes described in the PMBOK Guide. In this post facto study, we verified that the solutions drawn from a project using Lean Six Sigma methodology and based on PMBOK enabled the improvement of our processes dealing with the management of scientific research carried out in the institution and constitutes a model to contribute to the search of innovative science management solutions by other institutions dealing with scientific research in Brazil.

Nasal hygiene with saline solutions has been shown to relieve congestion, reduce the thickening of the mucus and keep nasal cavity clean and moist. Evaluating whether saline solutions improve nasal inspiratory flow among healthy children. Students between 8 and 11 years of age underwent 6 procedures with saline solutions at different concentrations. The peak nasal inspiratory flow was measured before and 30 min after each procedure. Statistical analysis was performed by means of t test, analysis of variance, and Tukey's test, considering p<0.05. We evaluated 124 children at all stages. There were differences on the way a same concentration was used. There was no difference between 0.9% saline solution and 3% saline solution by using a syringe. The 3% saline solution had higher averages of peak nasal inspiratory flow, but it was not significantly higher than the 0.9% saline solution. It is important to offer various options to patients.

Stuttering is a speech fluency disorder, and may be associated with neuroaudiological factors linked to central auditory processing, including changes in auditory processing skills and temporal resolution. To characterize the temporal processing and long-latency auditory evoked potential in stutterers and to compare them with non-stutterers. The study included 41 right-handed subjects, aged 18-46 years, divided into two groups: stutterers (n=20) and non-stutters (n=21), compared according to age, education, and sex. All subjects were submitted to the duration pattern tests, random gap detection test, and long-latency auditory evoked potential. Individuals who stutter showed poorer performance on Duration Pattern and Random Gap Detection tests when compared with fluent individuals. In the long-latency auditory evoked potential, there was a difference in the latency of N2 and P3 components; stutterers had higher latency values. Stutterers have poor performance in temporal processing and higher latency values for N2 and P3 components. Copyright © 2017 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial.

Multivariate logistic regression modeling was used to identify variables associated with self-reported high blood pressure with α < 0.05. Prevalence of self-reported high blood pressure among adults living in Brazilian state capitals and the Federal District was 24.1%. The following variables were associated with self-reported high blood pressure: age group, taking 18-24 as reference (all age groups presented increased risk - from 25-34 years [OR = 2.6; 95%CI 2.0-3.4] up to 65 years or more [OR = 28.1; 95%CI 21.7-36.4]); low education level (9 to 11 years of study [OR = 0.8; 95%CI 0.7-0.9] and 12 years or more [OR = 0.6; 95%CI 0.6-0.7]); Black race or skin color (OR = 1.3; 95%CI 1.1-1.5); being a former smoker (OR = 1.2; 95%CI 1.1-1.3); obesity (OR = 2.7; 95%CI 2.4-3.0); diabetes (OR = 2.9; 95%CI 2.5-3.5%), and high cholesterol (OR = 1.9; 95%CI 1.8-2.2). Approximately one quarter of the adult population living in Brazilian state capitals reported having high blood pressure. Information from Vigitel is useful to monitor high blood pressure and identity its associated factors, supporting public policies for health promotion, surveillance and care.

Since decades, Forensic Medicine is mainly taught by didactic methods but in last couple of years some other teachinglearning and assessment methods are also introduced at some places which also lacks uniformity. Feedback from learners is most fundamental aspect to assess effectiveness of applied methods, but is not implemented in practice at most medical schools in India. Unfortunately, medical students are deprived of this practical empowerment and thus may not be efficient enough to contribute potentially to the justice system during their professional life. In order to improve their efficiency in the field, we introduced few innovative teaching-learning methods and documented their perceptions. This pilot study was carried out with students who had completed their second professional year (5th semester) of medical curriculum. Students were exposed to few innovative teaching-learning and assessment approaches in addition to conventional methods during their Forensic Medicine term. These approaches were interactivity in large group lecturing, small group activities, student led objective tutorial, court visit in real scenario, practical records book, surprise tests, structured theory question papers, model answers, objective structured practical examinations and structured oral viva. Their perceptions were documented later through structured questionnaire. Students reported all methods as 'interesting' except 'surprise tests'. Court visits were rated highest for generating interest (98%). Clarity of concept was experienced through all methods (range of 71-95%). Interactive large group lectures reported highest (by 95%students) for clarifying concepts, although this is not a typical characteristic of large group teaching. Enhanced learning experience was reported in 75-92.5% for different methods. Student Led Objective Tutorials seemed to facilitate enhance learning most (92.5%). Innovations in teaching-learning are need of hour especially in subject like Forensic

To determine the impact of immigration status as well as race/ethnicity and social and economic factors on breastfeeding initiation. Cohort. Multisite group practice in eastern Massachusetts. One thousand eight hundred twenty-nine pregnant women prospectively followed up in Project Viva. Whether the participant breastfed her infant. The overall breastfeeding initiation rate was 83%. In multivariate models that included race/ethnicity and social, economic, and demographic factors, foreign-born women were more likely to initiate breastfeeding than US-born women (odds ratio [OR], 3.2 [95% confidence interval (CI), 2.0-5.2]). In models stratified by both race/ethnicity and immigration status, and further adjusted for whether the mother herself was breastfed as an infant and the mother's parents' immigration status, US-born and foreign-born black and Hispanic women initiated breastfeeding at rates at least as high as US-born white women (US-born black vs US-born white women, OR, 1.2 [95% CI, 0.8-1.9], US-born Hispanic vs US-born white women, OR, 1.1 [95% CI, 0.6-1.9], foreign-born black vs US-born white women, OR, 2.6 [95% CI, 1.1-6.0], and foreign-born Hispanic vs US-born white women, OR, 1.8 [95% CI, 0.7-4.8]). Calculations of predicted prevalences showed that, for example, the 2.6-fold increase in odds for the foreign-born black vs US-born white women translated to an increase in probability of approximately 1.4. Higher maternal education and household income also predicted higher initiation rates. Immigration status was strongly associated with increased breastfeeding initiation in this cohort, implying that cultural factors are important in the decision to breastfeed. Immigrants of all races/ethnicities initiated breastfeeding more often than their US-born counterparts. In addition, US-born minority groups initiated breastfeeding at rates at least as high as their white counterparts, likely due in part to high levels of education and income as well as to access to

Nearly 18,000 candidates securing 60% and above marks in Higher Secondary School Certificate (HSSC) examination contest for admission in Medical Colleges, in Punjab, Pakistan by sitting in the Medical College Admission Test (MCAT) each summer. This cross-sectional study was conducted to identify patterns related to demographic, economic and educational backgrounds, over a two-year-period, in this population, and how HSSC and MCAT marks predict future performance of the selected candidates. Marks obtained by candidates in HSSC, MCAT, and 1st Professional MBBS (Part-I) Examinations over two years 2008-2009, were analysed using parametric tests in SPSS. Total 18,090 candidates in 2008 and 18,486 in 2009 sat in the MCAT. National IHSSC candidates scored higher marks in HSSC and MCAT but lower marks than their foreign qualified HSSC counterparts (e.g., Advanced-levels from Cambridge University, UK) in Part-I overall and in all its subcomponents individually (p < 0.05). Female students scored higher marks than males in HSSC (p > 0.05). MCAT (p > 0.05) and Part-I theory, practical, viva voce, continuous assessment and Objective-Structured Performance Evaluation (OSPE) components (p < 0.05). In both years, students from the Dera Ghazi Khan District scored the highest marks in the HSSC Examinations (p < 0.05) but least marks in MCAT in 2008 (p < 0.05) and in Part-I in 2008 and 2009 (p < 0.05). Students from 'tougher' Boards like Rawalpindi in 2008 and the Federal Board in 2009 who scored least marks in HSSC scored highest marks in MCAT. and in Part-I Examinations (p < 0.05). Linear regression on Part-I by taking HSSC and MCAT marks as independent variables showed that the MCAT marks exerted the greatest positive influence consistently at 0.104 (2008) and 0.106 (2009). In 2009 HSSC marks were shown to exert a negative influence (-0.08) on Part-I. There is need to standardise HSSC education and examination across all Intermediate Boards. MCAT is a better predictor of Medical

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.

Allergen-specific IgG 4 (sIgG 4 ) antibodies are often associated with tolerance, but sIgG 4 antibodies to causally relevant foods have been reported recently in adults with eosinophilic esophagitis (EoE). Prevalence and levels of food sIgG 4 are not well established in the general pediatric population. We sought to investigate serum food sIgG 4 with component diagnostics in children with EoE and children from an unselected birth cohort and to explore the effects of sex, age, and milk consumption on sIgG 4 levels. Sera from 71 pediatric patients with EoE and 210 early adolescent children from an unselected birth cohort (Project Viva) were assayed for sIgG 4 and specific IgE (sIgE) to major cow's milk (CM) proteins (α-lactalbumin, β-lactoglobulin, and caseins) and to wheat, soy, egg, and peanut proteins. In the EoE cohort high-titer sIgG 4 (≥10 μg/mL) to CM proteins was more common than in control sera and achieved odds ratios for EoE ranging from 5.5 to 8.4. sIgE levels to CM proteins were mostly 4 IU/mL or less in patients with EoE, such that sIgG 4 /sIgE ratios were often 10,000 or greater. When adjusted for age and milk consumption, high-titer sIgG 4 to CM proteins was strongly associated with EoE, with an odds ratio of greater than 20 to all 3 CM proteins in boys. sIgG 4 to CM proteins are common and high titer in children with EoE. Although it is not clear that this response is pathogenic, sIgG 4 levels imply that these antibodies are an important feature of the local immune response that gives rise to EoE.

Early postnatal antibiotic use has been shown to promote excess weight gain, but it is unclear whether intrauterine exposure to antibiotics is associated with foetal growth and adiposity. The objective of this study was to examine associations of antibiotic prescription in each trimester of pregnancy with foetal size and adipokine levels at birth. In 2128 pregnant women from the pre-birth Project Viva cohort, from electronic medical records, we estimated antibiotic prescribing by timing during pregnancy. Outcomes were sex-specific birth weight-for-gestational-age z-score (BW/GA-z) and levels of umbilical cord leptin and adiponectin. We used linear regression models adjusted for maternal age, pre-pregnancy body mass index, parity, race/ethnicity, education, smoking during pregnancy, household income and child sex and additionally adjusted cord blood leptin and adiponectin models for gestation length. Of the 2128 women in our sample, 643 (30.2%) were prescribed with oral antibiotics during pregnancy. Mean (standard deviation) BW/GA-z was 0.17 (0.97), cord blood leptin was 9.0 ng mL -1 (6.6) and cord blood adiponectin was 28.8 ng mL -1 (6.8). Overall, antibiotic prescription in pregnancy was associated with lower BW/GA-z [multivariable adjusted β -0.11; 95% confidence interval {CI} -0.20, -0.01]. In trimester-specific analyses, only second trimester antibiotic prescription was associated with lower BW/GA-z (β -0.23; 95% CI -0.37, -0.08). Overall, antibiotic prescription in pregnancy was not associated with cord blood leptin or adiponectin levels. However, in trimester-specific analyses, third trimester antibiotic prescription was associated with higher cord blood leptin (β 2.28 ng mL -1 ; 95% CI 0.38, 4.17). Antibiotics in mid-pregnancy were associated with lower birth weight for gestational age, whereas third trimester antibiotics were associated with higher cord blood leptin. © 2016 World Obesity Federation.

Background: Few studies have examined whether prenatal exposure to perfluoroalkyl substances (PFASs) is associated with childhood adiposity. Objective: We examined associations of prenatal exposure to PFASs with adiposity in early and mid-childhood. Methods: We measured plasma PFAS concentrations in 1,645 pregnant women (median, 9.6 weeks gestation) enrolled in Project Viva, a prospective pre-birth cohort study in Massachusetts (USA), between 1999 and 2002. We assessed overall and central adiposity in 1,006 children in early childhood (median, 3.2 years) and 876 in mid-childhood (median, 7.7 years) using anthropometric and dual X-ray absorptiometry (DXA) measurements. We fitted multivariable linear regression models to estimate exposure-outcome associations and evaluated effect modification by child sex. Results: Median (25–75th percentiles) prenatal plasma perfluorooctanoate (PFOA), perfluorooctane sulfonate (PFOS), perfluorohexane sulfonate (PFHxS), and perfluorononanoate (PFNA) concentrations in children assessed in early childhood were 5.6 (4.1–7.7), 24.8 (18.4–33.9), 2.4 (1.6–3.8), and 0.6 (0.5–0.9) ng/mL, respectively. Among girls, each interquartile range increment of prenatal PFOA concentrations was associated with 0.21 kg/m2 (95% CI: –0.05, 0.48) higher body mass index, 0.76 mm (95% CI: –0.17, 1.70) higher sum of subscapular and triceps skinfold thickness, and 0.17 kg/m2 (95% CI: –0.02, 0.36) higher DXA total fat mass index in mid-childhood. Similar associations were observed for PFOS, PFHxS, and PFNA. We observed null associations for boys and early-childhood adiposity measures. Conclusions: In this cohort, prenatal exposure to PFASs was associated with small increases in adiposity measurements in mid-childhood, but only among girls.

Melanoma is a severe metastatic skin cancer with poor prognosis and no effective treatment. Therefore, novel therapeutic approaches using nanotechnology have been proposed to improve therapeutic effectiveness. Lipid-core nanocapsules (LNCs), prepared with poly(ε-caprolactone), capric/caprylic triglyceride, and sorbitan monostearate and stabilized by polysorbate 80, are efficient as drug delivery systems. Here, we investigated the effects of acetyleugenol-loaded LNC (AcE-LNC) on human SK-Mel-28 melanoma cells and its therapeutic efficacies on melanoma induced by B16F10 in C57B6 mice. LNC and AcE-LNC had z-average diameters and zeta potential close to 210 nm and -10.0 mV, respectively. CytoViva® microscopy images showed that LNC and AcE-LNC penetrated into SK-Mel-28 cells, and remained in the cytoplasm. AcE-LNC in vitro treatment (18–90×109 particles/mL; 1 hour) induced late apoptosis and necrosis; LNC and AcE-LNC (3–18×109 particles/mL; 48 hours) treatments reduced cell proliferation and delayed the cell cycle. Elevated levels of nitric oxide were found in supernatant of LNC and AcE-LNC, which were not dependent on nitric oxide synthase expressions. Daily intraperitoneal or oral treatment (days 3–10 after tumor injection) with LNC or AcE-LNC (1×1012 particles/day), but not with AcE (50 mg/kg/day, same dose as AcE-LNC), reduced the volume of the tumor; nevertheless, intraperitoneal treatment caused toxicity. Oral LNC treatment was more efficient than AcE-LNC treatment. Moreover, oral treatment with nonencapsulated capric/caprylic triglyceride did not inhibit tumor development, implying that nanocapsule supramolecular structure is important to the therapeutic effects. Together, data herein presented highlight the relevance of the supramolecular structure of LNCs to toxicity on SK-Mel-28 cells and to the therapeutic efficacy on melanoma development in mice, conferring novel therapeutic mechanisms to LNC further than a drug delivery system.

Study Objectives: To examine the association between race/ethnicity and sleep curtailment from infancy to mid-childhood, and to determine the extent to which socioeconomic and contextual factors both explain racial/ethnic differences and are independently associated with sleep curtailment. Methods: We studied 1,288 children longitudinally in Project Viva, a pre-birth cohort study, from 6 months to 7 years of age. The main exposure was the child's race/ethnicity. The main outcome was a sleep curtailment score from 6 months to 7 years. The score ranged from 0–13, where 0 indicated maximal sleep curtailment and 13 indicated never having curtailed sleep. Results: The mean (standard deviation) sleep curtailment score was 10.2 (2.7) points. In adjusted models (β [95% CI]), black (−1.92, [−2.39, −1.45] points), Hispanic (−1.58, [−2.43, −0.72] points), and Asian (−1.71, [−2.55, −0.86] points) children had lower sleep scores than white children. Adjustment for sociodemographic covariates attenuated racial/ethnic differences in sleep scores for black (by 24%) and Hispanic children (by 32%) but strengthened the differences for Asian children by 14%. Further adjustment for environmental and behavioral variables did not substantially change these differences. Independently, low maternal education, living in households with incomes < $70,000, viewing more TV, and having a TV in the child's bedroom were associated with lower sleep scores. Conclusions: Chronic sleep curtailment from infancy to mid-childhood was more prevalent among black, Hispanic, and Asian children. These differences were partially but not entirely explained by socio-contextual variables. Independently, children from lower socioeconomic status and those with greater exposures to TV also had greater sleep curtailment.

To examine the association between television/video (TV) viewing and markers of diet quality among 3-year-old children. We studied 613 boys and 590 girls, age 3 years old, who were participants in Project Viva. Each mother reported the number of hours her child watched TV on an average weekday and weekend day in the past month, from which we calculated a weighted mean. The main outcomes were intakes of selected foods and nutrients from a validated food frequency questionnaire. In linear regression models we adjusted for mother's sociodemographic information, parental body mass index (BMI), and child's age, sex, race/ethnicity, BMI z-score, sleep duration, and breast feeding duration. Mean (standard deviation, SD) age of subjects was 3.2 (0.2) years; 372 children (31%) were non-white and 151 (13%) had a household income < $40 000, and 330 mothers (28%) had completed less than a college degree. Mean (SD) TV viewing was 1.7 (1.0) hours per day. For each 1-hour increment of TV viewing per day, we found higher intakes of sugar-sweetened beverages (0.06 servings/day [95% CI 0.03, 0.10]), fast food (0.32 servings/month [95% CI 0.16, 0.49]), red and processed meat (0.06 servings/day [95% CI 0.02, 0.09]), total energy intake (48.7 kcal/day [95% CI 18.7, 78.6]), and percent energy intake from trans fat (0.05 [95% CI 0.03, 0.07]). We found lower intakes of fruit and vegetables (-0.18 servings/day [95% CI -0.32, -0.05]), calcium (-24.6 mg/day [95% CI -41.0, -8.1]), and dietary fiber (-0.44 g/day [95% CI -0.65, -0.22]). Among 3-year-olds, more TV viewing is associated with adverse dietary practices. Interventions to reduce TV viewing in this age group may lead to improved diet quality.

The ability to non-invasively measure body composition in mouse models of obesity and obesity-related disorders is essential for elucidating mechanisms of metabolic regulation and monitoring the effects of novel treatments. These studies aimed to develop a fully automated, high-throughput micro-computed tomography (micro-CT)-based image analysis technique for longitudinal quantitation of adipose, non-adipose and lean tissue as well as bone and demonstrate utility for assessing the effects of two distinct treatments. An initial validation study was performed in diet-induced obesity (DIO) and control mice on a vivaCT 75 micro-CT system. Subsequently, four groups of DIO mice were imaged pre- and post-treatment with an experimental agonistic antibody specific for anti-fibroblast growth factor receptor 1 (anti-FGFR1, R1MAb1), control immunoglobulin G antibody, a known anorectic antiobesity drug (rimonabant, SR141716), or solvent control. The body composition analysis technique was then ported to a faster micro-CT system (CT120) to markedly increase throughput as well as to evaluate the use of micro-CT image intensity for hepatic lipid content in DIO and control mice. Ex vivo chemical analysis and colorimetric analysis of the liver triglycerides were performed as the standard metrics for correlation with body composition and hepatic lipid status, respectively. Micro-CT-based body composition measures correlate with ex vivo chemical analysis metrics and enable distinction between DIO and control mice. R1MAb1 and rimonabant have differing effects on body composition as assessed by micro-CT. High-throughput body composition imaging is possible using a modified CT120 system. Micro-CT also provides a non-invasive assessment of hepatic lipid content. This work describes, validates and demonstrates utility of a fully automated image analysis technique to quantify in vivo micro-CT-derived measures of adipose, non-adipose and lean tissue, as well as bone.

Study Objectives: Fear of sleep may play a significant role in sleep disturbances in individuals with posttraumatic stress disorder (PTSD). This report describes a psychometric study of the Fear of Sleep Inventory (FoSI), which was developed to measure this construct. Methods: The psychometric properties of the FoSI were examined in a non-clinical sample of 292 college students (Study I) and in a clinical sample of 67 trauma-exposed adults experiencing chronic nightmares (Study II). Data on the 23 items of the FoSI were subjected to exploratory factor analyses (EFA) to identify items uniquely assessing fear of sleep. Next, reliability and validity of a 13-item version of the FoSI was examined in both samples. Results: A 13-item Short-Form version (FoSI-SF) was identified as having a clear 2-factor structure with high internal consistency in both the non-clinical (α = 0.76–0.94) and clinical (α = 0.88-0.91) samples. Both studies demonstrated good convergent validity with measures of PTSD (0.48-0.61) and insomnia (0.39-0.48) and discriminant validity with a measure of sleep hygiene (0.19-0.27). The total score on the FoSI-SF was significantly higher in the clinical sample (mean = 17.90, SD = 12.56) than in the non-clinical sample (mean = 4.80, SD = 7.72); t357 = 8.85 p < 0.001. Conclusions: Although all items are recommended for clinical purposes, the data support the use of the 13-item FoSI-SF for research purposes. Replication of the factor structure in clinical samples is needed. Results are discussed in terms of limitations of this study and directions for further research.

Genetic variants responsible for susceptibility to obesity and its comorbidities among Hispanic children have not been identified. The VIVA LA FAMILIA Study was designed to genetically map childhood obesity and associated biological processes in the Hispanic population. A genome-wide association study (GWAS) entailed genotyping 1.1 million single nucleotide polymorphisms (SNPs) using the Illumina Infinium technology in 815 children. Measured genotype analysis was performed between genetic markers and obesity-related traits i.e., anthropometry, body composition, growth, metabolites, hormones, inflammation, diet, energy expenditure, substrate utilization and physical activity. Identified genome-wide significant loci: 1) corroborated genes implicated in other studies (MTNR1B, ZNF259/APOA5, XPA/FOXE1 (TTF-2), DARC, CCR3, ABO); 2) localized novel genes in plausible biological pathways (PCSK2, ARHGAP11A, CHRNA3); and 3) revealed novel genes with unknown function in obesity pathogenesis (MATK, COL4A1). Salient findings include a nonsynonymous SNP (rs1056513) in INADL (p = 1.2E-07) for weight; an intronic variant in MTNR1B associated with fasting glucose (p = 3.7E-08); variants in the APOA5-ZNF259 region associated with triglycerides (p = 2.5-4.8E-08); an intronic variant in PCSK2 associated with total antioxidants (p = 7.6E-08); a block of 23 SNPs in XPA/FOXE1 (TTF-2) associated with serum TSH (p = 5.5E-08 to 1.0E-09); a nonsynonymous SNP (p = 1.3E-21), an intronic SNP (p = 3.6E-13) in DARC identified for MCP-1; an intronic variant in ARHGAP11A associated with sleep duration (p = 5.0E-08); and, after adjusting for body weight, variants in MATK for total energy expenditure (p = 2.7E-08) and in CHRNA3 for sleeping energy expenditure (p = 6.0E-08). Unprecedented phenotyping and high-density SNP genotyping enabled localization of novel genetic loci associated with the pathophysiology of childhood obesity. PMID:23251661

Optimal management of acute myeloid leukemia (AML) requires monitoring of treatment response, but minimal residual disease (MRD) may escape detection. We sought to identify distinctive features of AML cells for universal MRD monitoring. We compared genome-wide gene expression of AML cells from 157 patients with that of normal myeloblasts. Markers encoded by aberrantly expressed genes, including some previously associated with leukemia stem cells, were studied by flow cytometry in 240 patients with AML and in nonleukemic myeloblasts from 63 bone marrow samples. Twenty-two (CD9, CD18, CD25, CD32, CD44, CD47, CD52, CD54, CD59, CD64, CD68, CD86, CD93, CD96, CD97, CD99, CD123, CD200, CD300a/c, CD366, CD371, and CX3CR1) markers were aberrantly expressed in AML. Leukemia-associated profiles defined by these markers extended to immature CD34+CD38- AML cells; expression remained stable during treatment. The markers yielded MRD measurements matching those of standard methods in 208 samples from 52 patients undergoing chemotherapy and revealed otherwise undetectable MRD. They allowed MRD monitoring in 129 consecutive patients, yielding prognostically significant results. Using a machine-learning algorithm to reduce high-dimensional data sets to 2-dimensional data, the markers allowed a clear visualization of MRD and could detect 1 leukemic cell among more than 100,000 normal cells. The markers uncovered in this study allow universal and sensitive monitoring of MRD in AML. In combination with contemporary analytical tools, the markers improve the discrimination between leukemic and normal cells, thus facilitating data interpretation and, hence, the reliability of MRD results.

Children with sensorineural hearing loss can present with instabilities in postural control, possibly as a consequence of hypoactivity of their vestibular system due to internal ear injury. To assess postural control stability in students with normal hearing (i.e., listeners) and with sensorineural hearing loss, and to compare data between groups, considering gender and age. This cross-sectional study evaluated the postural control of 96 students, 48 listeners and 48 with sensorineural hearing loss, aged between 7 and 18 years, of both genders, through the Balance Error Scoring Systems scale. This tool assesses postural control in two sensory conditions: stable surface and unstable surface. For statistical data analysis between groups, the Wilcoxon test for paired samples was used. Students with hearing loss showed more instability in postural control than those with normal hearing, with significant differences between groups (stable surface, unstable surface) (p<0.001). Students with sensorineural hearing loss showed greater instability in the postural control compared to normal hearing students of the same gender and age.

KIELING, CHRISTIAN; HERRMAN, HELEN; PATEL, VIKRAM; MARI, JAIR DE JESUS

2009-01-01

There is a marked underepresentation of low- and middle-income countries (LAMIC) in the psychiatric literature, which may reflect an overall low representation of LAMIC publications in databases of indexed journals. This paper investigates the worldwide distribution of indexed psychiatric journals. A survey in both Medline and ISI Web of Science was performed in order to identify journals in the field of psychiatry according to their country of origin. Two hundred and twenty-two indexed psychiatric journals were found. Of these, 213 originated from high-income countries and only nine (4.1%) from middle-income countries. None were found in low-income countries. We also present the experience of a LAMIC psychiatric journal, the Revista Brasileira de Psiquiatria, in its recent indexation process. This case study may serve as an example for other LAMIC journals to pursue indexation in major databases as a strategy to widen the international foundation of psychiatric research. There is an important need for the inclusion of LAMIC psychiatric publications in the major indexation databases. This process will require multiple agents to partner with journals from LAMIC to improve their quality and strengthen their chances of being indexed. PMID:19293959

Correlation of bispectral index (BIS) monitoring and end-tidal sevoflurane concentration in a patient with lobar holoprosencephaly.

The bispectral index (BIS) is a parameter derived by electroencephalography (EEG) which provides a direct measurement of the effects of sedatives and anesthetics on the brain and offers guidance on the adequacy of anesthesia. The literature lacks studies on BIS monitoring in pediatric patients with congenital brain disease undergoing general anesthesia. A 13-year-old child weighing 32kg, suffering from lobar holoprosencephaly, underwent surgery in which the bispectral index (BIS) monitoring the depth of anesthesia showed an abnormal response. Detailed analysis of the trends of BIS values in the different observation times demonstrated sudden falls and repetitive values of BIS likely related to repetitive epileptiform electrical activity caused by sevoflurane. The BIS is a very useful monitoring tool for assessing the degree of depth of anesthesia and to analyze the electroencephalographic variations of anesthetics. Particular attention should be given to patients with congenital disorders of the central nervous system in which the BIS may give abnormal responses that do not reflect an accurate assessment of the depth of anesthesia.

2015-01-01

A burn patient is a challenge for any anesthesiologist, undergoing several surgeries during admission, and requiring general anesthesia and muscle relaxation most of the times. The victim may have respiratory system impairment and a response to muscle relaxants that differs from the healthy patient, thus proper monitoring and reversal is crucial. We analyzed sugammadex effectiveness and safety in this population. It was a prospectively descriptive study, including 4 patients, and all of them were considered major burn patients, who underwent escharotomy with general anesthesia and neuromuscular relaxation. The main variable was the time for recovery of a TOF higher than 0.9 after the administration of sugammadex before extubation. Mean time of recovery from a TOF ratio higher than 0.9 following the administration of Sugammadex was of 4.95min 95% CI (3.25-6.64, p=.53). The reversion of neuromuscular relaxation with sugammadex appears to be effective and safe in the burn patient. More analytical, comparative studies of larger populations would be necessary to confirm these data. Copyright © 2015 Sociedade Brasileira de Anestesiologia. Published by Elsevier Editora Ltda.

A 58-year-old female without cardiovascular risk factors, was going to be operated to repair the rotator cuff. Induction and interscalene brachial plexus block were uneventful, but after her placement for surgery the patient started with severe bronchospasm, hypotension, cutaneous allergic reaction and ST elevation on the electrocardiogram. An anaphylactic shock was suspected and treated but until the perfusion of nitroglycerina was started no electrocardiographic changes resolved. After necessary diagnostic test the final diagnosis was variant I of Kounis syndrome due to cefazolin and rocuronium. Ephinephrine is the cornerstone of treatment for anaphylaxis but should we use it if the anaphylactic reaction is also accompanied by myocardial ischemia? The answer is that we should not use it because myocardial ischemia in this syndrome is caused by vasospasm, so it would be more useful drugs such as nitroglycerin. But what if we do not know if it is a Kounis syndrome or not? In this article we report our experience that maybe could help you in a similar situation.

[Anesthesia and Alzheimer disease - Current perceptions].

PubMed

Marques, Ana Filipa Vieira da Silva Ferreira; Lapa, Teresa Alexandra Santos Carvalho

It has been speculated that the use of anesthetic agents may be a risk factor for the development of Alzheimer disease. The objective of this review is to describe and discuss pre-clinical and clinical data related to anesthesia and this disease. Alzheimer disease affects about 5% of the population over 65 years old, with age being the main risk factor and being associated with a high morbidity. Current evidence questions a possible association between anesthesia, surgery, and long-term cognitive effects, including Alzheimer disease. Although data from some animal studies suggest an association between anesthesia and neurotoxicity, this link remains inconclusive in humans. We performed a review of the literature in which we selected scientific articles in the PubMed database, published between 2005 and 2016 (one article from 1998 due to its historical relevance), in English, which address the possible relationship between anesthesia and Alzheimer disease. 49 articles were selected. The possible relationship between anesthetic agents, cognitive dysfunction, and Alzheimer disease remains to be clarified. Prospective cohort studies or randomized clinical trials for a better understanding of this association will be required. Copyright © 2017 Sociedade Brasileira de Anestesiologia.

To analyze the scientific literature on dietary changes in preterm children during the first years of life. The PubMed database was used for article selection. The texts were analyzed according to their objectives, research design, and research group characteristics. The following were selected to comprise the criteria: (1) publications in the period from 1996 to 2014; (2) participation of infants and children from birth to 10 years of age; (3) development of oral motor skills necessary for feeding; (4) development of the feeding process; and (5) feeding difficulties during childhood. There were 282 studies identified, of which 17 were used in the review, and five more articles were identified through the reference list of selected articles, totaling 22 references. Very low birth weight preterm newborns are more likely to have feeding problems in early postnatal stages and during childhood when compared with full-term infants. Monitoring the feeding of these infants after hospital discharge is strictly recommended in an early intervention program aiming at better development of feeding skills.

2008-05-02

The exposition to heavy metal-rich airborne due to fire practicing has forced to the development of heavy metal-free environmental ammunition primers all over the world. Here we characterize the GSR elements present in the Brazilian lead-free ammunition produced by Companhia Brasileira de Cartuchos (CBC) and commercialized by MagTech in the U.S. and Europe under the name CleanRange centerfire cartridges. Both first and second generations of CleanRange in calibers 9 mm Luger, .40 S&W, .380 AUTO and .38 SPL were analyzed and compared to regular Brazilian CBC ammunition by scanning electron microscopy/energy dispersive spectroscopy. Differences in composition and morphology of GSR particles from the two generations of CleanRange were observed. The first generation ammunition (found in Europe) presented spherical particles, being strontium the only unique element detected. The second generation (found in the U.S.) produced irregular particles composed mostly by potassium, aluminum, silicon and calcium. We can conclude that identification of GSR derived from CBC second generation lead-free ammunition in suspects' hands may be impossible without the addition of a distinct metallic taggant in the primer composition by the manufacturer.

Soria, Franciele Savaris; Silva, Roberta Gonçalves da; Furkim, Ana Maria

2016-01-01

During the aging process, one of the functions that changes is swallowing. These alterations in oropharyngeal swallowing may be diagnosed by methods that allow both the diagnosis and biofeedback monitoring by the patient. One of the methods recently described in the literature for the evaluation of swallowing is the Sonar Doppler. To compare the acoustic parameters of oropharyngeal swallowing between different age groups. This was a field, quantitative, study. Examination with Sonar Doppler was performed in 75 elderly and 72 non-elderly adult subjects. The following acoustic parameters were established: initial frequency, first peak frequency, second peak frequency; initial intensity, final intensity; and time for the swallowing of saliva, liquid, nectar, honey, and pudding, with 5- and 10-mL free drinks. Objective, measurable data were obtained; most acoustic parameters studied between adult and elderly groups with respect to consistency and volume were significant. When comparing elderly with non-elderly adult subjects, there is a modification of the acoustic pattern of swallowing, regarding both consistency and food bolus volume.

Tinnitus and sound intolerance are frequent and subjective complaints that may have an impact on a patient's quality of life. To present a review of the salient points including concepts, pathophysiology, diagnosis and approach of the patient with tinnitus and sensitivity to sounds. Literature review with bibliographic survey in LILACS, SciELO, Pubmed and MEDLINE database. Articles and book chapters on tinnitus and sound sensitivity were selected. The several topics were discussed by a group of Brazilian professionals and the conclusions were described. The prevalence of tinnitus has increased over the years, often associated with hearing loss, metabolic factors and inadequate diet. Medical evaluation should be performed carefully to guide the request of subsidiary exams. Currently available treatments range from medications to the use of sounds with specific characteristics and meditation techniques, with variable results. A review on tinnitus and auditory sensitivity was presented, allowing the reader a broad view of the approach to these patients, based on scientific evidence and national experience.

Production of native arbuscular mycorrhizal fungi inoculum under different environmental conditions.

PubMed

Torres-Arias, Yamir; Fors, Rosalba Ortega; Nobre, Camila; Gómez, Eduardo Furrazola; Berbara, Ricardo Luis Louro

In order to obtain an arbuscular mycorrhizal fungi (AMF) native inoculum from Sierra de Moa and determine the most appropriate conditions for its big scale production, four light and temperature combinations were tested in three plant species (Calophyllum antillanum, Talipariti elatum and Paspalum notatum). Growth and development parameters, as well as the mycorrhizal functioning of the seedlings were evaluated. The natural light treatment under high temperatures (L-H) was the most suitable for the growth and development of the three plant species, showing the highest total biomass values, mainly of root, and a positive root-shoot ratio balance. This treatment also promoted higher values of root mycorrhizal colonization, external mycelium and AMF spore density. A total of 38 AMF species were identified among the plants and environmental conditions tested. Archaeospora sp.1, Glomus sp.5, Glomus brohultii and G. glomerulatum were observed in all the treatments. The L-H condition can be recommended for native inoculum production, as it promotes a better expression of the AM symbiosis and an elevated production of mycorrhizal propagules.

Foot drop in postoperative period is very rare after spinal anesthesia. Early clinical assessment and diagnostic interventions is of prime importance to establish the etiology and to start appropriate management. Close follow-up is warranted in early postoperative period in cases when patient complain paresthesia or pain during needle insertion or drug injection. A 22-year-old male was undergone lower limb orthopedic surgery in spinal anesthesia. During shifting from postoperative ward footdrop was suspected during routine assessment of regression of spinal level. Immediately the patient was referred to a neurologist and magnetic resonance imaging was done, which was inconclusive. Conservative management was started and nerve conduction study was done on the 4th postoperative day that confirmed pure motor neuropathy of right peroneal nerve. Patient was discharged with ankle splint and physiotherapy after slight improvement in motor power (2/5). Foot drop is very rare after spinal anesthesia. Any suspected patient must undergo emergent neurological consultation and magnetic resonance imaging to exclude major finding and need for early surgical intervention.

The anesthesiologist must be aware of the causes, diagnosis and treatment of venous air embolism and adopt the practice patterns to prevent its occurrence. Although venous air embolism is a known complication of cesarean section, we describe an unusual inattention that causes iatrogenic near fatal venous air embolism during a cesarean section under spinal anesthesia. One of the reasons for using self-collapsible intravenous (IV) infusion bags instead of conventional glass or plastic bottles is to take precaution against air embolism. We also demonstrated the risk of air embolism for two kinds of plastic collapsible intravenous fluid bags: polyvinyl chloride (PVC) and polypropylene-based. Fluid bags without self-sealing outlets pose a risk for air embolism if the closed system is broken down, while the flexibility of the bag limits the amount of air entry. PVC-based bags, which have more flexibility, have significantly less risk of air entry when IV administration set is disconnected from the outlet. Using a pressure bag for rapid infusion can be dangerous without checking and emptying all air from the IV bag. 2013 Sociedade Brasileira de Anestesiologia. Published by Elsevier Editora Ltda.

Musicians have more robust and efficient neural responses in the cortical and sub-cortical regions, demonstrating that musical experience benefits the processing of both non-linguistic and linguistic stimuli. This study aimed to verify P300's latency and amplitude behavioral using contralateral stimulation in musicians and non-musicians. This was a case-control study. Subjects were divided in two groups: musicians, comprising 30 professional musicians, and non-musicians, comprising 25 subjects without musical experience. The present study showed that the musicians had lower latencies and higher amplitudes than the non-musicians in the P300 without contralateral noise. For the P300 amplitude values, the difference between groups persisted, and the musicians presented significantly higher amplitude values compared with the non-musicians; additionally, the analysis of the noise effect on the P300 response showed that the latency values were significantly increased in the musicians. The central auditory nervous system of musicians presents peculiar characteristics of electrophysiological responses probably due to the plasticity imposed by musical practice.

to analyze the changes in human milk macronutrients: fat, protein, and lactose in natural human milk (raw), frozen and thawed, after administration simulation by gavage and continuous infusion. an experimental study was performed with 34 human milk samples. The infrared spectrophotometry using the infrared analysis equipment MilkoScan Minor® (Foss, Denmark) equipment was used to analyze the macronutrients in human milk during the study phases. The analyses were performed in natural (raw) samples and after freezing and fast thawing following two steps: gavage and continuous infusion. The non-parametric Wilcoxon test for paired samples was used for the statistical analysis. the fat content was significantly reduced after administration by continuous infusion (p<0.001) during administration of both raw and thawed samples. No changes in protein and lactose content were observed between the two forms of infusion. However, the thawing process significantly increased the levels of lactose and milk protein. the route of administration by continuous infusion showed the greatest influence on fat loss among all the processes required for human milk administration.

To review the clinical characteristics, comorbidities, and management of insomnia in childhood and adolescence. This was a non-systematic literature review carried out in the PubMed database, from where articles published in the last five years were selected, using the key word "insomnia" and the pediatric age group filter. Additionally, the study also included articles and classic textbooks of the literature on the subject. During childhood, there is a predominance of behavioral insomnia as a form of sleep-onset association disorder (SOAD) and/or limit-setting sleep disorder. Adolescent insomnia is more associated with sleep hygiene problems and delayed sleep phase. Psychiatric (anxiety, depression) or neurodevelopmental disorders (attention deficit disorder, autism, epilepsy) frequently occur in association with or as a comorbidity of insomnia. Insomnia complaints in children and adolescents should be taken into account and appropriately investigated by the pediatrician, considering the association with several comorbidities, which must also be diagnosed. The main causes of insomnia and triggering factors vary according to age and development level. The therapeutic approach must include sleep hygiene and behavioral techniques and, in individual cases, pharmacological treatment. Copyright © 2015 Sociedade Brasileira de Pediatria.

Infectivity of housefly, Musca domestica (Diptera: Muscidae) to different entomopathogenic fungi.

PubMed

Farooq, Muzammil; Freed, Shoaib

The housefly Musca domestica is a worldwide insect pest that acts as a vector for many pathogenic diseases in both people and animals. The present study was conducted to evaluate the virulence of different local isolates of Beauveria bassiana, Metarhizium anisopliae and Isaria fumosorosea on M. domestica using two bioassay techniques: (1) adult immersion and (2) a bait method applied to both larvae and adults. The results showed evidence of a broad range of responses by both stages (larvae and adults) to the tested isolates of B. bassiana, M. anisopliae and I. fumosorosea. These responses were concentration-dependent, with mortality percentages ranging from 53.00% to 96.00%. Because it resulted in lower LC 50 values and a shorter lethal time, B. bassiana (Bb-01) proved to be the most virulent isolate against both housefly larvae and adults. Sublethal doses of the tested isolates were also assessed to evaluate their effect on M. domestica fecundity and longevity. The fungal infections reduced housefly survival regardless of their sex and also decreased egg production in females. Copyright © 2016 Sociedade Brasileira de Microbiologia.

To determine the prevalence of benign febrile seizures of childhood and describe the clinical and epidemiological profile of this population. This was a population-based, cross-sectional study, carried out in the city of Barra do Bugres, MT, Brazil, from August 2012 to August 2013. Data were collected in two phases. In the first phase, a questionnaire that was previously validated in another Brazilian study was used to identify suspected cases of seizures. In the second phase, a neurological evaluation was performed to confirm diagnosis. The prevalence was 6.4/1000 inhabitants (95% CI: 3.8-10.1). There was no difference between genders. Simple febrile seizures were found in 88.8% of cases. A family history of febrile seizures in first-degree relatives and history of epilepsy was present in 33.3% and 11.1% of patients, respectively. The prevalence of febrile seizures in Midwestern Brazil was lower than that found in other Brazilian regions, probably due to the inclusion only of febrile seizures with motor manifestations and differences in socioeconomic factors among the evaluated areas.

Pythium insidiosum: inhibitory effects of propolis and geopropolis on hyphal growth.

PubMed

Araújo, Maria José Abigail Mendes; Bosco, Sandra de Moraes Gimenes; Sforcin, José Maurício

Propolis and geopropolis are resinous products of bees showing antimicrobial effects. There is no data concerning their action against Pythium insidiosum - the causative agent of pythiosis, a pyogranulomatous disease of the subcutaneous tissue that affects mostly horses, dogs and humans. Fragments of 15 isolates of P. insidiodum were incubated with propolis and geopropolis extracts and evaluated for up to seven days to detect the minimal fungicidal concentration (MFC). Propolis inhibited three isolates at 1.0mgmL -1 after 24h and all other isolates at 3.4mgmL -1 . Geopropolis led to more variable results, exerting predominantly a fungistatic action than a fungicidal one. Propolis was more efficient than geopropolis in inhibiting P. insidiosum since lower concentrations led to no growth after 24h. This effect may be due to propolis chemical composition, which has more active compounds than geopropolis. Propolis seemed to be a good candidate for in vivo studies, since treatment with conventional antifungal compounds is difficult in most of the cases, requiring extensive surgical debridement.

Biofertilizer Ning shield was composed of different strains of plant growth promotion bacteria. In this study, the plant growth promotion and root-knot nematode disease control potential on Trichosanthes kirilowii in the field were evaluated. The application of Ning shield significantly reduced the diseases severity caused by Meloidogyne incognita, the biocontrol efficacy could reached up to 51.08%. Ning shield could also promote the growth of T. kirilowii in the field by increasing seedling emergence, height and the root weight. The results showed that the Ning shield could enhance the production yield up to 36.26%. Ning shield could also promote the plant growth by increasing the contents of available nitrogen, phosphorus, potassium and organic matter, and increasing the contents of leaf chlorophyll and carotenoid pigment. Moreover, Ning shield could efficiently enhance the medicinal compositions of Trichosanthes, referring to the polysaccharides and trichosanthin. Therefore, Ning shield is a promising biofertilizer, which can offer beneficial effects to T. kirilowii growers, including the plant growth promotion, the biological control of root-knot disease and enhancement of the yield and the medicinal quality.

To analyze the association between household smoking and the development of learning in elementary schoolchildren. Cross-sectional study with 785 students from the 2nd to the 5th year of elementary school. Students were evaluated by the School Literacy Screening Protocol to identify the presence of learning disabilities. Mothers/guardians were interviewed at home through a validated questionnaire. Descriptive and bivariate analysis, as well as multivariate Poisson regression, were performed. In the final model, the variables associated with learning difficulties were current smoking at the household in the presence of the child (PR=6.10, 95% CI: 4.56 to 8.16), maternal passive smoking during pregnancy (PR=1.46, 95% CI: 1.07 to 2.01), students attending the 2nd and 3rd years of Elementary School (PR=1.44, 95% CI: 1.10 to 1.90), and being children of mothers with only elementary level education (PR=1.36, 95% CI: 1.04 to 1.79). The study demonstrated an association between passive exposure to tobacco smoke and learning difficulties at school. Copyright © 2016 Sociedade Brasileira de Pediatria.

This study aimed to identify markers of metabolic syndrome (MS) in patients with phenylketonuria (PKU). This was a cross-sectional study consisting of 58 PKU patients (ages of 4-15 years): 29 patients with excess weight, and 29 with normal weight. The biochemical variables assessed were phenylalanine (phe), total cholesterol, HDL-c, triglycerides, glucose, and basal insulin. The patients had Homeostasis Model Assessment (HOMA) and waist circumference assessed. No inter-group difference was found for phe. Overweight patients had higher levels of triglycerides, basal insulin, and HOMA, but lower concentrations of HDL-cholesterol, when compared to the eutrophic patients. Total cholesterol/HDL-c was significantly higher in the overweight group. A positive correlation between basal insulin level and HOMA with waist circumference was found only in the overweight group. The results of this study suggest that patients with PKU and excess weight are potentially vulnerable to the development of metabolic syndrome. Therefore, it is necessary to conduct clinical and laboratory monitoring, aiming to prevent metabolic changes, as well as excessive weight gain and its consequences, particularly cardiovascular risk.

To review current models and scientific evidence on the influence of parents' oral health behaviors on their children's dental caries. MEDLINE articles published between 1980 and June, 2012. Original research articles on parents' oral health behavior were reviewed. A total of 218 citations were retrieved, and 13 articles were included in the analysis. The studies were eligible for review if they matched the following inclusion criteria: (1) they evaluated a possible association between dental caries and parents' oral-health-related behaviors, and (2) the study methodology included oral clinical examination. The main search terms were "oral health", "parental attitudes", "parental knowledge", and "dental caries". : 13 experimental studies contributed data to the synthesis. Original articles, reviews, and chapters in textbooks were also considered. Parents' dental health habits influence their children's oral health. Oral health education programs aimed at preventive actions are needed to provide children not only with adequate oral health, but better quality of life. Special attention should be given to the entire family, concerning their lifestyle and oral health habits. Copyright © 2013 Sociedade Brasileira de Pediatria. Published by Elsevier Editora Ltda.

The current reports are insufficient to determine the causative agent, as well as to identify high risk profiles for BS, leaving a clear need for more studies to this end. This study aimed to evaluate the correlation between weekly workload and BS dimensions. An observational, descriptive, cross-sectional study performed with 43 anesthesiologists from Maceió-AL, with the application of Maslach Burnout Inventory (MBI) forms. Pearson's correlation coefficient r was used for the three dimensions and a 95% confidence interval for the prevalence of burnout syndrome and high scores in all three dimensions. Among the studied physicians, 51.16% were male and the average age was 49.82±12.05 years. For physicians who have been diagnosed with BS through the MBI, the average weekly working time 69.27±22.39hours. The high level of frequency in at least one of the three dimensions was found in 67.44% of physicians, with this percentage being considered diagnostic for burnout syndrome in this population. This study showed no correlation between the weekly working time and the BS dimensions in this population. Copyright © 2016 Sociedade Brasileira de Anestesiologia.

Many conditions such as bacterial and viral infectious diseases, mechanical obstruction due to air and calculi and drugs can cause parotitis. We present a case of unusual bilateral parotitis in a patient under non-invasive continuous positive airway pressure (CPAP) therapy for chronic obstructive pulmonary disease exacerbation in intensive care unit. A 36-year-old patient was admitted to intensive care unit with the diagnosis of chronic obstructive pulmonary disease exacerbation. Antibiotherapy, bronchodilator therapy and non-invasive positive pressure ventilation were applied as treatment regimen. Painless swellings developed on the 3rd day of admission on the right and a day after this on the left parotid glands. Amylase levels were increased and ultrasonographic evaluation revealed bilateral parotitis. No intervention was made and the therapy was continued. The patient was discharged on the 6th day with clinical improvement and regression of parotid swellings without any complications. Parotitis may have occurred after retrograde air flow in the Stensen duct during CPAP application. After the exclusion of possible viral and bacteriological etiologies and possible drug reactions we can focus on this diagnosis. Copyright © 2014 Sociedade Brasileira de Anestesiologia.

Silva, Filipe Glória; Silva, Cláudia Rocha; Braga, Lígia Barbosa; Neto, Ana Serrão

2014-01-01

To validate the Portuguese version of the Children's Sleep Habits Questionnaire (CSHQ-PT) and compare it to the versions from other countries. The questionnaire was previously adapted to the Portuguese language according to international guidelines. 500 questionnaires were delivered to the parents of a Portuguese community sample of children aged 2 to 10 years old. 370 (74%) valid questionnaires were obtained, 55 children met exclusion criteria and 315 entered in the validation study. The CSHQ-PT internal consistency (Cronbach's α) was 0.78 for the total scale and ranged from 0.44 to 0.74 for subscales. The test-retest reliability for subscales (Pearson's correlations, n=58) ranged from 0.59 to 0.85. Our data did not adjust to the original 8 domains structure in Confirmatory Factor Analysis but the Exploratory Factor Analysis extracted 5 factors that have correspondence to CSHQ subscales. The CSHQ-PT evidenced psychometric properties that are comparable to the versions from other countries and adequate for the screening of sleep disturbances in children from 2 to 10 years old.

Fox, Nigel A

2007-01-01

Searches were made using the Cochrane Central Register of Controlled Trials, Medline, Embase, Latin American and Caribbean Health Sciences Literature, Bibliografia Brasileira de Odontologia and SciELO (the Scientific Electronic Library Online). Studies chosen were randomised controlled trials (RCT) or quasi-RCT comparing all types of oral and functional orthopaedic appliances with placebo or no treatment, in children of 15 years old or younger. Data were independently extracted by two review authors. Authors were contacted for additional information. Risk ratios with 95% confidence intervals were calculated for all important dichotomous outcomes. A total of 384 trials were identified, of which only one, reporting results from a total of 23 patients, was suitable for inclusion in the review. Data provided in the published report did not answer all the questions from this review, but did answer some: the results presented favour treatment. At present there is not sufficient evidence to state that oral appliances or functional orthopaedic appliances are effective in the treatment of obstructive sleep apnoea (OSA) syndrome in children. Oral appliances or functional orthopaedic appliances may be helpful in the treatment of children with craniofacial anomalies which are risk factors for apnoea.

2007-01-01

To assess and compare quality of abstracts presented at a medical congress (XIV Congresso da Sociedade Brasileira de Infectologia, November, 2005). The hypothesis is that material of better quality is chosen for oral presentation. All the 63 abstracts selected for oral presentation were compared with a random sample (n=63) of the 664 abstracts registered as poster presentations. Quality was measured by a structured questionnaire comprised of 33 criteria, distributed in eight categories: purpose, research design, setting, subjects, intervention, measurement, results and conclusions. The questionnaire was applied by one of the authors who were not blind to the objective of the study. The final score could range from 0 (bad) to 1 (excellent). Abstracts quality was considered moderately good. The overall mean quality scores were 0.60 and 0.62 respectively, for poster and oral presentation (p = 0.086). The criteria rated poorly were: subjects, variable measurements, location and conclusion. The tested hypothesis of better quality in abstracts selected for oral presentation has not been confirmed. It is recommended that organizers of the congresses the use of objective quality criteria to select the form of presentation while improving on quality.

Fibromyalgia syndrome (FMS) is a chronic disease that causes pain and fatigue, presenting a negative impact on quality of life. Exercise helps maintaining physical fitness and influences directly on the improvement of quality of life. Develop a protocol for health-related physical fitness assessment of patients with FMS with tests that are feasible and appropriate for this population. An exploratory and analytical literature review was performed, seeking to determine the tests used by the scientific community. With this in mind, we performed a literature revision through the use of virtual libraries databases: PubMed, Bireme, Banco de Teses e Dissertações da Capes and Biblioteca Digital Brasileira de Teses e Dissertações, published in between 1992-2012. A variety of tests was found; the following, by number of citations, stood out: Body Mass Index (BMI) and bioimpedance; 6-minute walk; handgrip strength (dynamometer, 1RM [Repetition Maximum]); Sit and reach and Shoulder flexibility; Foot Up and Go, and Flamingo balance. These are the tests that should make up the protocol for the physical evaluation of FMS patients, emphasizing their ease of use.

PubMed

Li, Li; Mu, Lan; Wang, Xiaojuan; Yu, Jingfeng; Hu, Ruiping; Li, Zhen

This study aimed to describe a Bacillus subtilis expression system based on genetically modified B. subtilis. Abaecin, an antimicrobial peptide obtained from Apis mellifera, can enhance the effect of pore-forming peptides from other species on the inhibition of bacterial growth. For the exogenous expression, the abaecin gene was fused with a tobacco etch virus protease cleavage site, a promoter Pglv, and a mature beta-glucanase signal peptide. Also, a B. subtilis expression system was constructed. The recombinant abaecin gene was expressed and purified as a recombinant protein in the culture supernatant. The purified abaecin did not inhibit the growth of Escherichia coli strain K88. Cecropin A and hymenoptaecin exhibited potent bactericidal activities at concentrations of 1 and 1.5μM. Combinatorial assays revealed that cecropin A and hymenoptaecin had sublethal concentrations of 0.3 and 0.5μM. This potentiating functional interaction represents a promising therapeutic strategy. It provides an opportunity to address the rising threat of multidrug-resistant pathogens that are recalcitrant to conventional antibiotics. Copyright © 2017 Sociedade Brasileira de Microbiologia.

2013-01-01

To assess speech alterations in mouth-breathing children, and to correlate them with the respiratory type, etiology, gender, and age. A total of 439 mouth-breathers were evaluated, aged between 4 and 12 years. The presence of speech alterations in children older than 5 years was considered delayed speech development. The observed alterations were tongue interposition (TI), frontal lisp (FL), articulatory disorders (AD), sound omissions (SO), and lateral lisp (LL). The etiology of mouth breathing, gender, age, respiratory type, and speech disorders were correlated. Speech alterations were diagnosed in 31.2% of patients, unrelated to the respiratory type: oral or mixed. Increased frequency of articulatory disorders and more than one speech disorder were observed in males. TI was observed in 53.3% patients, followed by AD in 26.3%, and by FL in 21.9%. The co-occurrence of two or more speech alterations was observed in 24.8% of the children. Mouth breathing can affect speech development, socialization, and school performance. Early detection of mouth breathing is essential to prevent and minimize its negative effects on the overall development of individuals. Copyright © 2013 Sociedade Brasileira de Pediatria.

Metabolic and infectious pathologies in Brazilian medical literature: a review.

PubMed

Rocha-e-Silva, Mauricio

2010-06-01

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

to review the evolution of acute respiratory distress syndrome (ARDS) definitions and present the current definition for the syndrome. a literature review and selection of the most relevant articles on ARDS definitions was performed using the MEDLINE®/PubMed® Resource Guide database (last ten years), in addition to including the most important articles (classic articles) that described the disease evolution. the review included the following subjects: introduction; importance of definition; description of the first diagnostic criterion and subsequently used definitions, such as acute lung injury score; definition by the American-European Consensus Conference, and its limitations; description of the definition by Delphi, and its problems; accuracy of the aforementioned definitions; description of most recent definition (the Berlin definition), and its limitations; and practical importance of the new definition. ARDS is a serious disease that remains an ongoing diagnostic and therapeutic challenge. The evolution of definitions used to describe the disease shows that studies are needed to validate the current definition, especially in pediatrics, where the data are very scarce.

Obesity is associated with the abnormal glucose metabolism preceding type 2 diabetes mellitus. Thus, further investigation on the prediction of this lethal outcome must be sought. The objective was the profile glycemic assessment of asymptomatic obese children and adolescents from Salvador, Brazil. A fasting venous blood sample was obtained from 90 consecutive obese individuals aged 8-18 years, of both sexes, for laboratory determinations of glycated hemoglobin, basal insulin, and the Homeostasis Model Assessment Insulin Resistance index. The clinical evaluation included weight, height, waist circumference, assessment of pubertal development, and acanthosis nigricans research. The body mass index/age indicator was used for the severity of overweight assessment. Glycemic alterations were evidenced clinically and biochemically, although these individuals had no complaints or symptoms related to blood sugar levels. Quantitative and qualitative variables were respectively expressed measures of central tendency/dispersion and simple/relative frequency, using the SPSS, version 20.0. A p-value <0.05 was considered significant. Notably, this study found a high prevalence of glucose and insulin disorders in asymptomatic obese children and adolescents.

To evaluate environmental obesogenic-related factors, such as physical activity in neighborhoods and schools, nutritional behavior, and intervention programs. Critical analysis of literature with personal point of view from infant obesity experts and political advisors for public intervention. Although obesity is a public health problem affecting several age groups, it is among children and adolescents that it plays a more important role, due to treatment complexity, high likelihood of persistence into adulthood, and association with other non-transmissible diseases while still in early age. Environment is a main component of the genesis and outcomes in the near future or long term. Modification of intake with high-density food, meal skipping, and high intake of saturated fat, sugar, and salt, associated to high levels of sedentarism are main causes of obesity. Intervention opportunities are related to modifications in political, environmental, and individual settings. School and physical activities in the educational environment are intertwined with nutrition intervention in continuous education. A critical review of some different scenarios in Latin American countries is presented. Copyright © 2016 Sociedade Brasileira de Pediatria. Published by Elsevier Editora Ltda. All rights reserved.

2015-01-01

To assess body composition modifications in post-pubertal schoolchildren after practice of a physical activity program during one school year. The sample consisted of 386 students aged between 15 and 17 years and divided into two groups: the study group (SG) comprised 195 students and the control group (CG), 191. The SG was submitted to a physical activity program and the CG attended conventional physical education classes. Body composition was assessed using body mass index (BMI), percentage of body fat (%BF), fat mass (FM), and lean mass (LM). A positive effect of the physical activity program on body composition in the SG (p<0.001) was observed, as well as on the interaction time x group in all the variables analyzed in both genders. A reduction in %BF (mean of differences = -5.58%) and waist circumference (-2.33 cm), as well as an increase in LM (+2.05 kg) were observed in the SG for both genders, whereas the opposite was observed in the CG. The practice of programmed physical activity promotes significant reduction of body fat in post-pubertal schoolchildren. Copyright © 2013 Sociedade Brasileira de Pediatria.

To identify associations between maternal restrictive feeding practices for child weight control and sociodemographic, behavioral, dietetic, and anthropometric characteristics. Cross-sectional study with mothers of children aged 2-8 years. Maternal feeding practices were measured by the Comprehensive Feeding Practices Questionnaire, in private schools in Brazil. Bivariate and multivariate associations were performed, using nonparametric analyses to estimate odds ratios and significance levels. Maternal restrictive feeding practices for weight control were independently associated with the mother's perception of her child being a little overweight/overweight/obese (OR=4.61, p=0.001), greater concern about the child's overweight (OR=2.61, p<0.001), child's overweight/obesity/severe obesity (OR= 2.18, p<0.001), and the child's greater intake of ultra-processed foods (OR=1.40, p=0.026). In this study, the risk variables identified for the use of the maternal restrictive feeding practices to control the child's weight can be used to provide education and guidance interventions in health and education networks directed to groups with similar characteristics to those of the studied population.

The effect of heavy metal contamination on the bacterial community structure at Jiaozhou Bay, China.

PubMed

Yao, Xie-Feng; Zhang, Jiu-Ming; Tian, Li; Guo, Jian-Hua

In this study, determination of heavy metal parameters and microbiological characterization of marine sediments obtained from two heavily polluted sites and one low-grade contaminated reference station at Jiaozhou Bay in China were carried out. The microbial communities found in the sampled marine sediments were studied using PCR-DGGE (denaturing gradient gel electrophoresis) fingerprinting profiles in combination with multivariate analysis. Clustering analysis of DGGE and matrix of heavy metals displayed similar occurrence patterns. On this basis, 17 samples were classified into two clusters depending on the presence or absence of the high level contamination. Moreover, the cluster of highly contaminated samples was further classified into two sub-groups based on the stations of their origin. These results showed that the composition of the bacterial community is strongly influenced by heavy metal variables present in the sediments found in the Jiaozhou Bay. This study also suggested that metagenomic techniques such as PCR-DGGE fingerprinting in combination with multivariate analysis is an efficient method to examine the effect of metal contamination on the bacterial community structure.

2018-03-13

To reduce the cost of obtaining bacterial cellulose, acidic by-products of the alcohol and dairy industries were used without any pretreatment or addition of other nitrogen sources. Studies have shown that the greatest accumulation of bacterial cellulose (6.19g/L) occurs on wheat thin stillage for 3 days of cultivation under dynamic conditions, which is almost 3 times higher than on standard Hestrin and Schramm medium (2.14g/L). The use of whey as a nutrient medium makes it possible to obtain 5.45g/L bacterial cellulose under similar conditions of cultivation. It is established that the pH of the medium during the growth of Gluconacetobacter sucrofermentans B-11267 depends on the feedstock used and its initial value. By culturing the bacterium on thin stillage and whey, there is a decrease in the acidity of the waste. It is shown that the infrared spectra of bacterial cellulose obtained in a variety of environments have a similar character, but we found differences in the micromorphology and crystallinity of the resulting biopolymer.

Tinnitus is a subjective sensation of hearing a sound in the absence of an external stimulus, which significantly worsens the quality of life in 15-25% of affected individuals. To assess the effectiveness of acupuncture therapy for tinnitus. Randomized clinical trial ( 2T9T7Q) with 50 participants with tinnitus, divided into two groups: 25 participants in the acupuncture group and 25 participants in the control group. The acupuncture group received acupuncture treatment and the control group received no treatment. After a period of 5 weeks, they were called to perform the final evaluation and the control group received acupuncture treatment for ethical reasons. A statistically significant result was found for the primary outcome, reducing the intensity of tinnitus, with p=0.0001 and the secondary endpoint, showing improvement in quality of life, with p=0.0001. Chinese scalp acupuncture associated with bilateral electroacupuncture demonstrated, in the short term, a statistically significant improvement by reducing the level of tinnitus intensity, as well as improving the quality of life of individuals with tinnitus.

Malfliet, Anneleen; Leysen, Laurence; Pas, Roselien; Kuppens, Kevin; Nijs, Jo; Van Wilgen, Paul; Huysmans, Eva; Goudman, Lisa; Ickmans, Kelly

In the last decade, evidence regarding chronic pain has developed exponentially. Numerous studies show that many chronic pain populations show specific neuroplastic changes in the peripheral and central nervous system. These changes are reflected in clinical manifestations, like a generalized hypersensitivity of the somatosensory system. Besides a hypersensitivity of bottom-up nociceptive transmission, there is also evidence for top-down facilitation of pain due to malfunctioning of the endogenous descending nociceptive modulatory systems. These and other aspects of modern pain neuroscience are starting to be applied within daily clinical practice. However, currently the application of this knowledge is mostly limited to the general adult population with musculoskeletal problems, while evidence is getting stronger that also in other chronic pain populations these neuroplastic processes may contribute to the occurrence and persistence of the pain problem. Therefore, this masterclass article aims at giving an overview of the current modern pain neuroscience knowledge and its potential application in post-cancer, paediatric and sports-related pain problems.

To investigate the effects of multidisciplinary treatment with and without psychological counseling on obese adolescents' self-reported quality of life. Seventy-six obese adolescents (15.87±1.53 y) were allocated into psychological counseling group (PCG; n=36) or control group (CG; n=40) for 12 weeks. All participants received the same supervised exercise training, nutritional and clinical counseling. Participants in PCG also received psychological counseling. QOL was measured before and after 12 weeks of intervention by Generic Questionnaire for the Evaluation of Quality of Life (SF-36). The dropout rate was higher in GC (22.5%) when compared with PCG (0.0%) (p<0.001). After 12 weeks, participants from PCG presents lower body weight, relative fat mass and higher free fat mass (p<0.001 for all) compared to GC. QOL improved among adolescents from both groups (p<0.05), however, a better QOL was reported from those adolescents enrolled in PCG. The inclusion of a psychological counseling component in multidisciplinary treatment for adolescent obesity appears to provide benefits observed for improved QOL as compared with treatment without psychological counseling.

We present a case of allergic reaction to patent blue in a patient who underwent excision of sentinel lymph node associated with segmental breast resection. About 20minutes after the dye injection, the patient developed hypotension (BP=70×30mmHg) associated with increased heart frequency. The patient was treated successfully with decreased inspired fraction of inhaled anesthetic and fluid replacement. At the end of the procedure, she presented with bluish urticarial - like plaques on the head, neck, upper limbs, and trunk; hydrocortisone was then used. The patient recovered uneventfully and was discharged from the PACU two hours after the end of surgery without skin changes, and was discharged from hospital on the morning after surgery. The incidence of allergic reactions with the use of patent blue is far superior to the hypersensitivity reactions seen with anesthetic and adjuvant drugs. Therefore, the anesthesiologist must be aware of cardiovascular instability associated with skin changes during the use of patent blue, for early diagnosis and appropriate treatment of this hypersensitivity reaction to this dye.

2010-12-01

Geographic studies and spatial analyses have been recognized in Brazilian public health papers. It is still, however, very little explored by researchers. In a survey of the leading scientific journals covering issues related to Brazilian worker's health, we found the predominant use of charts and tables as a way to organize and present results with a small number of maps. This survey was conducted by examining all papers published in four journals, covering the period from 1967 to 2009 (Revista de Saúde Pública, Cadernos de Saúde Pública, Revista Saúde e Sociedade, and Revista Brasileira de Epidemiologia). After analyzing the set of papers selected for the study, the papers that used maps were given special attention. The tools of geoprocessing and geostatistics with GIS support, although little used, open new possibilities to use thematic cartography in the field of workers' health. However, it is recommended that editors of scientific journals have detailed technical standards as well as specific reports for the publication of cartographic figures aimed at facilitating the modifications necessary for the improvement of the visual quality of maps and of the spatial correlations through cartography.

2016-01-01

Carbon monoxide is a toxic gas for humans and is still a silent killer in both developed and developing countries. The aim of this case series was to evaluate early radiological images as a predictor of subsequent neuropsychological sequelae, following carbon monoxide poisoning. After carbon monoxide exposure, early computed tomography scans and magnetic resonance imaging findings of a 52-year-old woman showed bilateral lesions in the globus pallidus. This patient was discharged and followed for 90 days. The patient recovered without any neurological sequela. In a 58-year-old woman exposed to carbon monoxide, computed tomography showed lesions in bilateral globus pallidus and periventricular white matter. Early magnetic resonance imaging revealed changes similar to that like in early tomography images. The patient recovered and was discharged from hospital. On the 27th day of exposure, the patient developed disorientation and memory impairment. Late magnetic resonance imaging showed diffuse hyperintensity in the cerebral white matter. White matter lesions which progress to demyelination and end up in neuropsychological sequelae cannot always be diagnosed by early computed tomography and magnetic resonance imaging in carbon monoxide poisoning.

To assess the performance of cerebrospinal fluid (CSF) lactate as a biomarker to differentiate bacterial meningitis from viral meningitis in children, and to define an optimal CSF lactate concentration that can be called significant for the differentiation. Children with clinical findings compatible with meningitis were studied. CSF lactate and other conventional CSF parameters were recorded. At a cut-off value of 3mmol/L, CSF lactate had a sensitivity of 0.90, specificity of 1.0, positive predictive value of 1.0, and negative predictive value of 0.963, with an accuracy of 0.972. The positive and negative likelihood ratios were 23.6 and 0.1, respectively. When comparing between bacterial and viral meningitis, the area under the curve for CSF lactate was 0.979. The authors concluded that CSF lactate has high sensitivity and specificity in differentiating bacterial from viral meningitis. While at a cut-off value of 3mmol/L, CSF lactate has high diagnostic accuracy for bacterial meningitis, mean levels in viral meningitis remain essentially below 2mmol/L.

Carissimi, Alicia; Adan, Ana; Tonetti, Lorenzo; Fabbri, Marco; Hidalgo, Maria Paz; Levandovski, Rosa; Natale, Vincenzo; Martoni, Monica

The present study aimed to investigate the relationship between physical self-efficacy and body mass index in a large sample of schoolchildren. The Perceived Physical Ability Scale for Children was administered to 1560 children (50.4% boys; 8-12 years) from three different countries. Weight and height were also recorded to obtain the body mass index. In agreement with the literature, the boys reported greater perceived physical self-efficacy than girls. Moreover, the number of boys who are obese is double that of girls, while the number of boys who are underweight is half that found in girls. In the linear regression model, the increase in body mass index was negatively related to the physical self-efficacy score, differently for boys and girls. Furthermore, age and nationality also were predictors of low physical self-efficacy only for girls. The results of this study reinforce the importance of psychological aspect of obesity, as the perceived physical self-efficacy and body mass index were negatively associated in a sample of schoolchildren for boys and girls.

Klippel-Feil syndrome (KFS) has a classical triad that includes short neck, low hair line and restriction in neck motion and is among one of the congenital causes of difficult airway. Herein, we present a 26-day, 3300g newborn with KFS who was planned to be operated for correction of an intestinal obstruction. She had features of severe KFS. Anesthesia was induced by inhalation of sevoflurane 2-3% in percentage 100 oxygen. Sevoflurane inhalation was stopped after 2min. Her Cornmack Lehane score was 2 and oral intubation was performed with 3.5mm ID non-cuffed endotracheal tube in first attempt. Operation lasted for 45min. Following uneventful surgery, she was not extubated and was transferred to the newborn reanimation unit. On the postoperative third day, the patient died due to hyperdynamic heart failure. This case is the youngest child with Klippel-Feil syndrome in literature and on whom oral intubation was performed. We also think that positioning of this younger age group might be easier than older age groups due to incomplete ossification process. Copyright © 2014 Sociedade Brasileira de Anestesiologia.

The selection of suitable reference genes is crucial for accurate quantification of gene expression and can add to our understanding of host-pathogen interactions. To identify suitable reference genes in Pandora neoaphidis, an obligate aphid pathogenic fungus, the expression of three traditional candidate genes including 18S rRNA(18S), 28S rRNA(28S) and elongation factor 1 alpha-like protein (EF1), were measured by quantitative polymerase chain reaction at different developmental stages (conidia, conidia with germ tubes, short hyphae and elongated hyphae), and under different nutritional conditions. We calculated the expression stability of candidate reference genes using four algorithms including geNorm, NormFinder, BestKeeper and Delta Ct. The analysis results revealed that the comprehensive ranking of candidate reference genes from the most stable to the least stable was 18S (1.189), 28S (1.414) and EF1 (3). The 18S was, therefore, the most suitable reference gene for real-time RT-PCR analysis of gene expression under all conditions. These results will support further studies on gene expression in P. neoaphidis. Copyright © 2015 Sociedade Brasileira de Microbiologia. Published by Elsevier Editora Ltda. All rights reserved.

In the current study, 18 halotolerant and halophilic bacteria have been investigated for their plant growth promoting abilities in vitro and in a hydroponic culture. The bacterial strains have been investigated for ammonia, indole-3-acetic acid and 1-aminocyclopropane-1-carboxylate-deaminase production, phosphate solubilisation and nitrogen fixation activities. Of the tested bacteria, eight were inoculated with Triticum aestivum in a hydroponic culture. The investigated bacterial strains were found to have different plant-growth promoting activities in vitro. Under salt stress (200mM NaCl), the investigated bacterial strains significantly increased the root and shoot length and total fresh weight of the plants. The growth rates of the plants inoculated with bacterial strains ranged from 62.2% to 78.1%. Identifying of novel halophilic and halotolerant bacteria that promote plant growth can be used as alternatives for salt sensitive plants. Extensive research has been conducted on several halophilic and halotolerant bacterial strains to investigate their plant growth promoting activities. However, to the best of my knowledge, this is the first study to inoculate these bacterial strains with wheat. Copyright © 2016 Sociedade Brasileira de Microbiologia.

Arslan-Aydoğdu, Elif Özlem; Kimiran, Ayten

Nine Legionella pneumophila strains isolated from cooling towers and a standard strain (L. pneumophila serogroup 1, ATCC 33152, Philadelphia 1) were analyzed and compared in terms of motility, flagella structure, ability to form biofilms, enzymatic activities (hemolysin, nucleases, protease, phospholipase A, phospholipase C, acid phosphatase, alkaline phosphatase and lipase), hemagglutination capabilities, and pathogenicity in various host cells (Acanthamoeba castellanii ATCC 30234, mouse peritoneal macrophages and human peripheral monocytes). All the isolates of bacteria appeared to be motile and polar-flagellated and possessed the type-IV fimbria. Upon the evaluation of virulence factors, isolate 4 was found to be the most pathogenic strain, while 6 out of the 9 isolates (the isolates 1, 2, 3, 4, 5, and 7) were more virulent than the ATCC 33152 strain. The different bacterial strains exhibited differences in properties such as adhesion, penetration and reproduction in the hosts, and preferred host type. To our knowledge, this is the first study to compare the virulence of environmental L. pneumophila strains isolated in Turkey, and it provides important information relevant for understanding the epidemiology of L. pneumophila.

Lignocellulose-derived inhibitors have negative effects on the ethanol fermentation capacity of Saccharomyces cerevisiae. In this study, the effects of eight typical inhibitors, including weak acids, furans, and phenols, on glucose and xylose co-fermentation of the recombinant xylose-fermenting flocculating industrial S. cerevisiae strain NAPX37 were evaluated by batch fermentation. Inhibition on glucose fermentation, not that on xylose fermentation, correlated with delayed cell growth. The weak acids and the phenols showed additive effects. The effect of inhibitors on glucose fermentation was as follows (from strongest to weakest): vanillin>phenol>syringaldehyde>5-HMF>furfural>levulinic acid>acetic acid>formic acid. The effect of inhibitors on xylose fermentation was as follows (from strongest to weakest): phenol>vanillin>syringaldehyde>furfural>5-HMF>formic acid>levulinic acid>acetic acid. The NAPX37 strain showed substantial tolerance to typical inhibitors and showed good fermentation characteristics, when a medium with inhibitor cocktail or rape straw hydrolysate was used. This research provides important clues for inhibitors tolerance of recombinant industrial xylose-fermenting S. cerevisiae. Copyright © 2017 Sociedade Brasileira de Microbiologia.

This study was conducted to isolate an acid-producing, alkaliphilic bacterium to reduce the alkalinity of cement industry waste (cement kiln dust). Gram-positive isolate KG1 grew well at pH values of 6-12, temperatures of 28-50°C, and NaCl concentrations of 0-16% and thus was further screened for its potential to reduce the pH of an alkaline medium. Phenotypic characteristics of the KG1 isolate were consistent with those of the genus Bacillus, and the highest level of 16S rRNA gene sequence similarity was found with Bacillus halodurans strain DSM 497 (94.7%). On the basis of its phenotypic characteristics and genotypic distinctiveness from other phylogenetic neighbors belonging to alkaliphilic Bacillus species, the isolated strain was designated B. halodurans strain KG1, with GenBank accession number JQ307184 (= NCIM 5439). Isolate KG1 reduced the alkalinity (by 83.64%) and the chloride content (by 86.96%) of cement kiln dust and showed a potential to be used in the cement industry for a variety of applications.
