Carlos Alberto da Silva Magliano,1 Andrea Libório Monteiro,2 Amanda Rebeca de Oliveira Rebelo,1 Claudia Cristina de Aguiar Pereira31Instituto Nacional de Cardiologia, INC, Rio de Janeiro, Brazil; 2Department of Pharmacy Systems, Outcomes and Policy, College of Pharmacy, University of Illinois at Chicago, Illinois, USA; 3Escola Nacional de Saúde Pública, ENSP, FIOCRUZ, Rio de Janeiro, BrazilAims: Guidelines current recommendations regarding the best treatment option for coronary revascularization are usually based on composite outcomes that were not selected or weighed with patients thence they may fail in representing patients’ preferences adequately. This systematic review aimed to appraise existing literature surrounding stated preference (SP) regarding coronary revascularization.Methods and results: Studies related to SP regarding coronary revascularization were searched on Medline, Embase and Lilacs databases. Two reviewers screened all titles independently, and consensus resolved any disagreements. Of 735 total citations, six studies were included and qualitatively synthesized. Notably, the attributes most often cited in these studies coincided with those already used in clinical trials (death, myocardial infarction, stroke and redo revascularization). Half of the studies analyzed the use of composite endpoints and showed the necessity to review this practice since the attributes are weighed differently, and there is a disagreement between patients and physicians. Also, a large variety of methods were used to elicitate and value the attributes such as rating, ranking, standard gamble, willingness to pay, and discrete choice experiments.Conclusion: Despite a large number of studies comparing revascularization treatment efficacy, there are just a few focusing on patients’ preferences. The selection of outcomes to be considered in the trade-off between treatment options and how to weigh them properly, taking into consideration patients’ preferences, need to be explored in future trials.Keywords: review, systematic, preference, patient, angioplasty, transluminal, percutaneous coronary, bypass surgery, coronary revascularization

In this study, we aim to evaluate the use of visual aids representing perioperative mortality and long-term survival in the communication process for patients diagnosed with coronary artery disease at the National Institute of Cardiology, a Brazilian public hospital specializing in cardiology. Patients and methods: One-on-one interviews were conducted between August 1 and November 20, 2017. Patients were asked to imagine that their doctor was seeking their input in the decision regarding which treatment represented the best option for them. Patients were required to choose between alternatives by considering only the different benefits and risks shown in each scenario, described as the proportion of patients who had died during the perioperative period and within 5 years. Each participant evaluated the same eight scenarios. We evaluated their answers in a qualitative and quantitative analysis. Results: The main findings were that all patients verbally expressed concern about perioperative mortality and that 25% did not express concern about long-term mortality. Twelve percent considered the probabilities irrelevant on the grounds that their prognosis would depend on “God’s will.” Ten percent of the patients disregarded the reported likelihood of perioperative mortality, deciding to focus solely on the “chance of being cured.” In the quantitative analysis, the vast majority of respondents chose the “correct” alternatives, meaning that they made consistent and rational choices. Conclusion: The use of visual aids to present risk attributes appeared feasible in our sample. The impact of heuristics and religious beliefs on shared health decision making needs to be explored better in future studies.

Carlos Alberto da Silva Magliano,1 Andrea Liborio Monteiro,2 Bernardo Rangel Tura,1 Claudia Silvia Rocha Oliveira,1 Amanda Rebeca de Oliveira Rebelo,1 Claudia Cristina de Aguiar Pereira3 1HTA Department, National Institute of Cardiology, Rio de Janeiro, Brazil; 2Department of Pharmacy Systems, Outcomes and Policy, College of Pharmacy, University of Illinois at Chicago, Chicago, IL, USA; 3The National School of Public Health Sergio Arouca ENSP/Fiocruz, Rio de Janeiro, Brazil Background: Patients with a diagnosis of coronary artery disease (CAD) may face important decisions regarding treatment options, with the “right choice” depending on the relative weights of risks and benefits. Studies performed as discrete choice experiments are used to estimate these weights, and attribute selection is an essential step in the design of these studies. Attributes not included in the design cannot be analyzed. In this study, we aimed to elicit, rank, and rate attributes that may be considered important to patients and physicians who must choose between angioplasty and surgery for coronary revascularization. Methods: The elicitation process involved performing a systematic review to search for attributes cited in declared preference studies in addition to face-to-face interviews with cardiologists and experts. The interviews were audio-recorded in digital format, and the collected data were transcribed and searched to identify new attributes. The criterion used to finish the data collection process was sampling saturation. Results: A systematic review resulted in the selection of the following 14 attributes: atrial fibrillation, heart failure, incision scar, length of stay, long-term survival, myocardial infarction, periprocedural death, postoperative infection, postprocedural angina, pseudoaneurysm, renal failure, repeat coronary artery bypass grafting, repeat percutaneous coronary intervention, and stroke. The interviews added no new attributes. After rating, we identified significant differences in the values that patients and cardiologists placed on renal insufficiency (p

- Abstract
Objectives: The development of measures such as the EQ-HWB (EQ Health and Wellbeing) requires selection of items. This study explored the psychometric performance of candidate items, testing their validity in patients, social carer users, and carers. Methods: Article and online surveys that included candidate items (N = 64) were conducted in Argentina, Australia, China, Germany, United Kingdom, and the United States. Psychometric assessment on missing data, response distributions, and known group differences was undertaken. Dimensionality was explored using exploratory and confirmatory factor analysis. Poorly fitting items were identified using information functions, and the function of each response category was assessed using category characteristic curves from item response theory (IRT) models. Differential item functioning was tested across key subgroups. Results: There were 4879 respondents (Argentina = 508, Australia = 514, China = 497, Germany = 502, United Kingdom = 1955, United States = 903). Where missing data were allowed, it was low (UK article survey 2.3%; US survey 0.6%). Most items had responses distributed across all levels. Most items could discriminate between groups with known health conditions with moderate to large effect sizes. Items were less able to discriminate across carers. Factor analysis found positive and negative measurement factors alongside the constructs of interest. For most of the countries apart from China, the confirmatory factor analysis model had good fit with some minor modifications. IRT indicated that most items had well-functioning response categories but there was some evidence of differential item functioning in many items. Conclusions: Items performed well in classical psychometric testing and IRT. This large 6-country collaboration provided evidence to inform item selection for the EQ-HWB measure.

In the European Union, Portugal is one of the countries with the highest levels of poverty and inequality. This is the reality that this article focuses on. The text provides statistical data that illustrate the evolution of poverty and income inequalities over the last decade (2011-2019), serving as a basis for a critical analysis of the consequences of economic cycles on it. In particular, how the combination of the economy (financial crisis), politics (austerity plan) and social context (low social contestation) has interfered with its worsening over the period 2011-2014. From this analysis, we develop the argument that if the negative alliance of the three factors makes a country poorer and more unequal, it is in turn the positive combination of the same factors that could lead to important advances in the fight against poverty and social inequality.

- Abstract
IntroductionOccupational accidents with biological material are an injury which can largely be prevented. This study describes the notified occupational accidents in the State of SÃêãão Paulo.MethodsDescriptive data analysis of the accidents with biological material notified by SINAN in the State of SÃêããão Paulo, in the period from 2007 to June 2016.ResultsDuring this period 1 25 060 accidents were reported with biological material. 77.5% occurred in female health professionals and most frequently in the 20 and 39 years age group, in nurses and lab technicians (53.1%) followed by physicians (10.7%). Regarding the accident circumstances, 17.1% occurred during the administration of medication, inappropriate disposal of syringes and needles (15.5%) and surgical and dental procedures (15.1%). The proportions of accidents by inappropriate disposal over time remained unchanged. The accidents in procedures of realisation of capillary blood glucose test and recapping needles had a proportional decrease of two times. It was observed that 30.2% of professionals who were injured were not using gloves when administering medication, and 15.3% and 14.7%, respectively, did not do so in the procedures of blood collection and laboratory collection. Glove use during accident in surgical and dental procedures occurred in 96.7% and 95.3%, respectively. The outpatient discharge of the injured professionals occurred in 39.6% (49,557) after confirming a negative source for hepatitis B, C and HIV (human immunodeficiency virus), in 22.1% (27,674) after six months of follow-up without serological conversion and in 11.6% due to abandonment of follow-up. In this period there were no cases of conversion to HIV.ConclusionReporting accidents with biological material is a great monitoring tool. Inadequate disposal of needles is an important cause of accidents, and their frequency remains unchanged over the years. The accidents in procedures of realisation of blood test and recapping needles had a decrease. Much more can be done to prevent accidents and improve the follow-up of accidents.

O trabalho foi realizado no Setor de Ovinocultura da Universidade de Marília, objetivando estudar os efeitos de três níveis de energia (2,6; 2,8 e 3,0 Mcal EM/kg MS) na ração de cordeiros inteiros Suffolk criados em creep feeding, sobre o desempenho e características de carcaça. Na parição numerava-se e registravam-se o peso ao nascer dos cordeiros que, posteriormente, foram distribuídos aleatoriamente, compondo doze repetições por tratamento. As rações foram isoprotéicas (18,46% PB) fornecidas ad libitum duas vezes ao dia, pesando-se as respectivas sobras. Os cordeiros foram pesados a cada 14 dias, permanecendo com as ovelhas até atingirem o peso vivo final, preestabelecido em 31 kg. Em seguida, os cordeiros permaneceram em jejum alimentar por 16 horas, até o momento do abate, obtendo-se o peso vivo ao abate. Após o abate, registraram-se os pesos da carcaça quente e do conteúdo digestivo, para o cálculo do peso de corpo vazio. As carcaças permanecerem por 24 horas na câmara de refrigeração em temperatura de 5ºC, obtendo-se o peso da carcaça fria. Para o ganho médio diário ocorreu diferença significativa entre os tratamentos, utilizando-se como covariável a idade de abate, com melhor desempenho para os cordeiros que receberam a ração com 3,0 Mcal EM. Para as características da carcaça não houve efeito dos tratamentos. Concluiu-se que o nível 3,0 Mcal EM foi o mais indicado para a ração de cordeiros Suffolk alimentados e terminados em creep feeding.

Climate change is of major relevance to wine production as most of the wine-growing regions of the world, in particular the Douro region, are located within relatively narrow latitudinal bands with average growing season temperatures limited to 13–21°C. This study focuses on the incidence of climate variables and indices that are relevant both for climate change detection and for grape production with particular emphasis on extreme events (e.g. cold waves, storms, heat waves). Dynamical downscaling of MPI-ESM-LR global data forced with RCP8.5 climatic scenario is performed with the Weather Research and Forecast (WRF) model to a regional scale including the Douro valley of Portugal for recent-past (1986–2005) and future periods (2046–2065; 2081–2100). The number, duration and intensity of events are superimposed over critical phenological phases of the vine (dormancy, bud burst, flowering, véraison, and maturity) in order to assess their positive or negative implications on wine production in the region. An assessment on the statistical significance of climatic indices, their differences between the recent-past and the future scenarios and the potential impact on wine production is performed. Preliminary results indicate increased climatic stress on the Douro region wine production and increased vulnerability of its vine varieties. These results will provide evidence for future strategies aimed to preserve the high-quality wines in the region and their typicality in a sustainable way.

Medicine ,Cytology ,QH573-671 - Abstract
Abstract In the last fifteen years, rapid progress has been made in delineating the cellular response to DNA damage. The DNA damage response network is composed of a large number of proteins with different functions that detect and signal the presence of DNA damage in order to coordinate DNA repair with a variety of cellular processes, notably cell cycle progression. This signal, which radiates from the chromatin template, is driven primarily by phosphorylation events, mainly on serine and threonine residues. While we have accumulated detailed information about kinases and their substrates our understanding of the role of phosphatases in the DNA damage response is still preliminary. Identifying the phosphatases and their regulation will be instrumental to obtain a complete picture of the dynamics of the DNA damage response. Here we give an overview of the DNA damage response in mammalian cells and then review the data on the role of different phosphatases and discuss their biological relevance.

Abstract Background Extensive bile duct proliferation is a key feature of the tissue reaction to clinical and experimental forms of liver injury. Experimental infection of mice by Schistosoma mansoni is a well-studied model of liver fibrosis with bile duct hyperplasia. However, the regulatory mechanisms of bile duct changes are not well understood. In this study we report the reproducible isolation of long-term cultures of cholangiocytes from mice livers with schistosomal fibrosis. Methods We have isolated a cholangiocyte cell line from Schistosoma-induced liver granulomas using a combination of methods including selective adhesion and isopyknic centrifugation in Percoll. Results The cell line was characterized by morphological criteria in optical and transmission electron microscopy, ability to form well differentiated ductular structures in collagen gels and by a positive staining for cytokeratin 18 and cytokeratin 19. To our knowledge, this is the first murine cholangiocyte cell line isolated from schistosomal fibrosis reported in the literature. Conclusion After 9 months and 16 passages this diploid cell line maintained differentiated characteristics and a high proliferative capacity. We believe the method described here may be a valuable tool to study bile duct changes during hepatic injury.

Abstract Background A marked expansion of the connective tissue population and an abnormal deposition of extracellular matrix proteins are hallmarks of chronic and acute injuries to liver tissue. Liver connective tissue cells, also called stellate cells, derived from fibrotic liver have been thoroughly characterized and correspond phenotypically to myofibroblasts. They are thought to derive from fat-storing Ito cells in the perisinusoidal space and acquire a contractile phenotype when activated by tissue injury. In the last few years it has become evident that several peptide growth factors such as PDGF AA and TGF-β are involved in the development of fibrosis by modulating myofibroblast proliferation and collagen secretion. The fact that during the development of chronic fibrosis there is concomitant deposition of collagen, a known inhibitory factor, and sustained cell proliferation, raises the possibility that stellate cells from chronic liver fibrosis patients fail to respond to normal physiologic controls. Methods In this study we address whether cells from fibrotic liver patients respond to normal controls of proliferation. We compared cell proliferation of primary human liver connective tissue cells (LCTC) from patients with liver fibrosis and skin fibroblasts (SF) in the presence of collagens type I and IV; TGF-β, PDGF AA and combinations of collagen type I and TGF-β or PDGF AA. Results Our results indicate that despite displaying normal contact and collagen-induced inhibition of proliferation LCTC respond more vigorously to lower concentrations of PDGF AA. In addition, we show that collagen type I synergizes with growth factors to promote mitogenesis of LCTC but not SF. Conclusions The synergistic interaction of growth factors and extracellular matrix proteins may underlie the development of chronic liver fibrosis.

Dupont J, Leal BC, Lozano P, Monteiro AL, Migowski P, and Scholten JD
- Abstract
Ionic liquids (ILs) have unique physicochemical properties that make them advantageous for catalysis, such as low vapor pressure, non-flammability, high thermal and chemical stabilities, and the ability to enhance the activity and stability of (bio)catalysts. ILs can improve the efficiency, selectivity, and sustainability of bio(transformations) by acting as activators of enzymes, selectively dissolving substrates and products, and reducing toxicity. They can also be recycled and reused multiple times without losing their effectiveness. ILs based on imidazolium cation are preferred for structural organization aspects, with a semiorganized layer surrounding the catalyst. ILs act as a container, providing a confined space that allows modulation of electronic and geometric effects, miscibility of reactants and products, and residence time of species. ILs can stabilize ionic and radical species and control the catalytic activity of dynamic processes. Supported IL phase (SILP) derivatives and polymeric ILs (PILs) are good options for molecular engineering of greener catalytic processes. The major factors governing metal, photo-, electro-, and biocatalysts in ILs are discussed in detail based on the vast literature available over the past two and a half decades. Catalytic reactions, ranging from hydrogenation and cross-coupling to oxidations, promoted by homogeneous and heterogeneous catalysts in both single and multiphase conditions, are extensively reviewed and discussed considering the knowledge accumulated until now.

- Abstract
Moxidectin (MOX) is used to control helminth parasites in ruminant livestock. It is released through feces and remains in the environment for a long period. This study aimed to evaluate the impact of faeces excreted by moxidectin-treated sheep on soil biodiversity (coprophagous insects, soil microbial biomass, and activity) to establish environment-related guidelines regarding the use of MOX in sheep livestock. The study consisted of two experiments. In the first one, faeces from MOX-treated (subcutaneous dose of 0.2 mg·kg
-1 body weight) and nontreated rams were placed on an animal-free pasture field, protected or not against rain, for 88 days. Then, coprophagous insects were captured, identified, and counted, and faeces degradation was evaluated by measuring dry weight and carbon (C) and nitrogen (N) contents over time. Diptera, Hymenoptera, Isoptera, and Coleoptera were equally encountered in faeces from MOX-treated and nontreated animals. Faecal boluses of MOX-treated animals (with higher N content) not protected against rain degraded faster than faecal boluses of nontreated animals (with lower N content). In the second experiment, faeces from nontreated animals were amended with increasing amounts of MOX (75 to 3,000 ng·kg-1 faeces), mixed with soil samples from animal-free pasture (1.9 to 75 ng·kg-1 soil), and incubated in a greenhouse for 28 days. Increasing concentrations of MOX did not prevent the growth of cultivable bacteria, actinobacteria, or fungi in culture media. However, even the lower MOX concentration (1.9 ng·kg-1 soil) abruptly decreased soil microbial biomass, basal respiration, and N mineralization. Thus, the results indicate that faeces excreted from sheep treated with MOX under the experimental conditions of this study are not harmful to the coprophagous insects. However, adding MOX to faeces from drug-free sheep had a negative impact on soil microbial activity and biomass., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2024 Susana Gilaverte Hentz et al.)- Published

- Abstract
Tetragonisca angustula (Latreille, 1811) is an indigenous neotropical stingless bee, popularly known as "Jataí", with a wide distribution in the Brazilian territory. T. angustula produces other derivatives such as propolis, geopropolis, fermented (saburá pollen), cerumen and resins, which are important in folk medicine. In this review, the objective was to gather research on the main plant species visited by T. angustula, as well as studies that verified the chemical composition and biological properties of T. angustula bioproducts. The bibliographic review was performed by searching the Scopus, Web of Science, ScienceDirect, and PubMed databases for publications from 2003 to February 2023. We found 78 studies that analyzed the interactions between T. angustula and floral species, with species from the botanical families Fabaceae, Asteraceae, Malvaceae, Bignoniaceae, Solanaceae, Myrtaceae and Lamiaceae being the most reported as the main food sources for this species. The presence of compounds belonging to the class of flavonoids, phenolic acids, terpenoids and alkaloids has been identified by studying the chemical composition of honey, propolis, geopropolis and fermented pollen (saburá) in 21 studies. The data collected in the literature emphasize that these T. angustula products have remarkable biological properties, especially their antibacterial and antioxidant activities., (© 2023 Wiley-VHCA AG, Zurich, Switzerland.)

- Abstract
The control of the oxidative stability of biodiesel and blends of biodiesel with diesel is one of the major concerns of the biofuel industry. The oxidative degradation of biodiesel can be accelerated by several factors, and this is most critical in the so-called second generation biodiesel, which is produced from low-cost raw materials with lower environmental impacts. The addition of antioxidants is imperative to ensure the oxidative stability of biodiesel, and these are considered products of high commercial value. The antioxidants currently available on the market are from synthetic origin, so the existence/availability of alternative antioxidants of natural origin (less dependent on fossil sources) at a competitive price presents itself as a strong business opportunity. This work describes and characterizes a sustainable alternative to synthetic antioxidants used in the biodiesel market developed from extracts of vineyard pruning waste (VPW), which are naturally rich in phenolic compounds with antioxidant properties. A hydrothermal extraction process was applied as a more efficient and sustainable technology than the conventional one with the potential of the extracts as antioxidant additives in biodiesel evaluated in Rancitech equipment. The VPW extract showed comparable antioxidant activity as the commercial antioxidant butylated hydroxytoluene (BHT) typically used in biodiesel. The stability of the biodiesel is dependent from the amount of the extract added. Further, for the first time, the assessment of the environmental impacts of using natural extracts to control the oxidative stability of biodiesel in the production process is also discussed as a key factor of the process environmental sustainability., Competing Interests: The authors declare no competing financial interest., (© 2023 The Authors.

- Abstract
Introduction: Health-related quality of life is expressed in utilities, also referred to as utility estimates or parameters. Considerations about the source and type of utility values are especially important in a modeling context, where the lack of transparency, including the lack of a hierarchy for utility data sources, is a major issue to any estimation and can potentially compromise model reliability., Objectives: This document aims to present the first version of the Brazilian guidelines for utility measurement to support economic analysis., Methods: A virtual workshop and a modified Delphi panel with 10 health technology specialists followed a rapid evaluation of 110 technical documents and indexed publications. The recommendations are based on the proposition that has received the most votes, although contentious issues are addressed in the suggestion or discussion. The rationale for the final decision is included in the text., Results: The consensus includes 50 recommendations with the following topics: Transparency and Reliability, Model Design, Conditions Under Which Generic Questionnaires Are Not Sensible or Valid, Utility Evidence Hierarchy, Utility Data Searching, Modeling Utility Values, Extrapolating Quality Adjusted Life-Years for Models With Lifetime Horizons, Caregiver Utility, Utility Data Synthesis, Quality/Certainty of the Evidence, and Utility Estimates in End-of-Life Conditions., Conclusions: The goal of this project is to create unified national standards for using utility metrics in economic analysis in Brazil. This set of recommendations is not obligatory, but it is meant to serve as a guide and lead to the development of better and more transparent economic models in the country., (Copyright © 2022 International Society for Health Economics and Outcomes Research.

- Abstract
Objectives: The EQ Health and Wellbeing Short (EQ-HWB-S) is a new broad generic measure of health and wellbeing for use in economic evaluations of interventions across healthcare, social care, and public health. This measure conceptually overlaps with the 5-level version EQ-5D (EQ-5D-5L), while expanding on the coverage of health and social care related dimensions. This study aims to examine the extent to which the EQ-HWB-S and EQ-5D-5L overlap and are different., Methods: A sample of US-based respondents (n = 903; n = 400 cancer survivors and n = 503 general population) completed a survey administered via an online panel. The survey included the EQ-HWB item pool (62 items, including 11 items used in this analysis), EQ-5D-5L, and questions about sociodemographic and health characteristics. The analysis included (Spearman's) correlations, the comparison of patterns of response (distributions and ceiling effects), and the ability to discriminate between known groups., Results: Moderate to strong associations were found between conceptually overlapping dimensions of the EQ-5D-5L and the EQ-HWB-S (r
s > 0.5, P < .001). Among respondents reporting full health on the EQ-5D-5L (n = 161, 18.23%), the EQ-HWB-S identified ceiling effects, particularly with the item "feeling exhausted." Most EQ-5D-5L and EQ-HWB-S items demonstrated discriminative ability among those with and without physical and mental conditions, yielding medium (> 0.5) to large effect sizes (> 0.8). Nevertheless, only EQ-HWB-S items distinguished between caregivers and noncaregivers and those with low and high caregiver burden, albeit with small effect sizes (0.2-0.5)., Conclusions: Results indicate a convergence between the measures, especially between overlapping dimensions, lending support to the validity of the EQ-HWB-S. The EQ-HWB-S performed similarly or better than the EQ-5D-5L among patient groups and is better able to differentiate among caregivers and respondents closer to full health., (Copyright © 2022.

- Abstract
Objectives: The development of measures such as the EQ-HWB (EQ Health and Wellbeing) requires selection of items. This study explored the psychometric performance of candidate items, testing their validity in patients, social carer users, and carers., Methods: Article and online surveys that included candidate items (N = 64) were conducted in Argentina, Australia, China, Germany, United Kingdom, and the United States. Psychometric assessment on missing data, response distributions, and known group differences was undertaken. Dimensionality was explored using exploratory and confirmatory factor analysis. Poorly fitting items were identified using information functions, and the function of each response category was assessed using category characteristic curves from item response theory (IRT) models. Differential item functioning was tested across key subgroups., Results: There were 4879 respondents (Argentina = 508, Australia = 514, China = 497, Germany = 502, United Kingdom = 1955, United States = 903). Where missing data were allowed, it was low (UK article survey 2.3%; US survey 0.6%). Most items had responses distributed across all levels. Most items could discriminate between groups with known health conditions with moderate to large effect sizes. Items were less able to discriminate across carers. Factor analysis found positive and negative measurement factors alongside the constructs of interest. For most of the countries apart from China, the confirmatory factor analysis model had good fit with some minor modifications. IRT indicated that most items had well-functioning response categories but there was some evidence of differential item functioning in many items., Conclusions: Items performed well in classical psychometric testing and IRT. This large 6-country collaboration provided evidence to inform item selection for the EQ-HWB measure., (Copyright © 2021 International Society for Pharmacoeconomics and Outcomes Research, Inc.

- Abstract
Introduction: Academic detailing (AD) is an educational outreach strategy to provide clinicians with current evidence-based information, which has been shown to change prescribing behaviours. The overall effectiveness of AD interventions is associated with prescriber satisfaction; however, most approaches use single items or non-validated measures. This study aims to develop and validate an instrument to assess prescriber satisfaction with AD interventions., Methods: A group of candidate items was generated and refined based on constructs identified through a literature review and in consultation with an expert panel. The initial instrument was piloted with 183 primary care providers who participated in an AD intervention on opioid-related pain management. To support the validity and reliability of the measure, psychometric properties were examined., Results: Ten candidate items were developed based on the following themes: acceptability, feasibility of implementation, usefulness, perception of efficacy, overall satisfaction, willingness to repeat and willingness to change. One item related to willingness to change did not contribute to assessing an individual's ability and lowered the measure's internal consistency and was therefore dropped., Conclusion: Results supported the validity and reliability of a refined 9-item measure of Provider Satisfaction with Academic Detailing (the PSAD). This measure should be considered for broad use across educational outreach programmes as a standardized measure to assess provider satisfaction and provide continuous quality improvement., Competing Interests: Disclosure and potential conflicts of interest: Dr Fischer has consulted for Alosha Health.

- Abstract
Spent caustic discharges are responsible for increasing oil and grease (O&G) matter in refineries wastewater, leading to increasing treatment costs due to low water quality and environmental constraints associated with high O&G concentration discharges. As a way to settle and optimize treatment technologies for such complex effluents, more insight regarding the effluents impact and deeper characterization is necessary. The present study intends to assess the possibility of a relationship between the processed crude oils with the polar O&G concentration in naphthenic spent caustic as well as in the final wastewater; Sines refinery was considered as case-study. Also, in order to get insights about the nature of the polar O&G compounds, their structures and their prevalence in the effluent treatment system was carried out through detailed analytical characterization studies. Proton nuclear magnetic resonance (
1 H NMR), Fourier transform infrared spectroscopy (FT-IR) and gas chromatography-mass spectrometry (GC-MS) were chosen. It was found that, for the Sines refinery, spent caustic discharges may increase the refinery effluent management cost up to 3 €/ton of processed crude oil, every time a high kerosene cut acid crude oil is processed. It was also found that the typical spent caustic O&G effluents are composed by organic contaminants with low molecular weight (MW), with aromatic and polar arrangements, like phenolic groups and naphthenic acids. This outcome is crucial for subsequently establishing the best technologies able to deal with such complex effluents., (Copyright © 2021 Elsevier B.V. All rights reserved.)- Published

- Abstract
Background: Weed control can be economically viable if implemented at the necessary time to minimize interference. Empirical mathematical models have been used to determine when to start the weed control in many crops. Furthermore, empirical models have a low generalization capacity to understand different scenarios. However, computational development facilitated the implementation of supervised machine learning models, as artificial neural networks (ANNs), capable of understanding complex relationships. The objectives of our work were to evaluate the ability of ANNs to estimate yield losses in onion (model crop) due to weed interference and compare with multiple linear regression (MLR) and empirical models., Results: MLR constructed from non-destructive and destructive methods show R
2 and root mean square error (RMSE) values varying between 0.75% and 0.82%, 13.0% and 19.0%, respectively, during testing step. The ANNs has higher R2 (higher than 0.95) and lower RMSE (less than 6.95%) compared to MLR and empirical models for training and testing steps. ANNs considering only the coexistence period and system have similar performance to MLR models. However, the insertion of variables related to weed density (non-destructive ANN) or fresh matter (destructive ANN) increases the predictive capacity of the networks to values close to 99% correct., Conclusion: The best performing ANNs can indicate the beginning of weed control since they can accurately estimate losses due to competition. These results encourage future studies implementing ANNs based on computer vision to extract information about the weed community., (© 2021 Society of Chemical Industry.)- Published

- Abstract
Locus of control (LOC) is a modifiable mediator of symptoms of posttraumatic stress disorder (PTSD) among traumatized individuals and a potential target of intervention. Compared with studies involving adults, the potential mediation effect of LOC on PTSD symptoms among trauma-exposed children and adolescents is relatively under-explored. This study, therefore, assessed the mediation effects of LOC on the association between lifetime cumulative trauma and PTSD symptoms among a large cohort of adolescents from different cultural background., Cross-sectional study., LOC was determined using the Multi-Dimension Locus of Control Scale; Posttraumatic stress symptoms using the UCLA PTSD Reaction Index; and other significant negative life events using the Life Events Checklist., Among 3826 adolescents who completed the study, external LOC explained 24% of variance ( R
2 = .24; F2,3823 = 619.01; p < .01) in PTSD symptoms and had significant indirect effect on the relationship between self-reported cumulative traumatic event exposure and PTSD symptoms (ß = .14; 95% BC CI [.10, .20]). Moderated mediation results showed significant potentiation of the moderation effects among older adolescents; boys; and those from more affluent families., The study further strengthened the hitherto limited evidence that external LOC partially mediate the relationship between cumulative trauma exposure and PTSD symptoms among adolescents.- Published

- Abstract
Background: The EQ-5D-3L is a widely used generic health-related quality of life measure commonly applied to describe health outcomes and to measure disease burden. The aim of this study was to generate Brazilian population norms, stratified by age and gender, based on Brazilian preference weights for EQ-5D-3L., Methods: A multicenter cross-sectional study was conducted in three Brazilian urban areas. The final sample consisted of 5774 respondents, aged from 18 to 64 years. Amongst other information, respondents were asked to self-report their health status using the EQ-5D-3L descriptive system and visual analog scale (EQ-VAS). Data on socio-demographic characteristics was obtained through specific questionnaires. The Brazilian TTO scoring algorithm was used to derive the utility values. Multivariate logistic regression models were fitted to analyze the influence of age, sex, education status and sample site on the presence of any problem for each dimension of EQ5D., Results: Mean values were computed for both weighted index scores and self-rated health status (EQ-VAS), and stratified by gender and age groups. Health status declines with age, ranging between 0.87 for the youngest group 18-29 year-olds and 0.76 for 60-64-year-old. Men reported higher scores (0.85) than the woman (0.79). Lower education levels were associated with lower EQ-5D index score in most age groups., Conclusion: This study provides EQ-5D reference values for the Brazilian population. These values can be used by local decision-makers and researchers in economic evaluations and population health studies.

- Abstract
Background: Exposure to traumatic events in childhood is associated with the development and maintenance of various psychiatric disorders, but most frequently with posttraumatic stress disorder (PTSD). The aim of this study was to evaluate the types of traumatic events experienced and the presence and predictors of PTSD symptoms among adolescents from the general population from ten low- and middle-income countries (LMICs)., Methods: Data were simultaneously collected from 3370 trauma-exposed adolescents (mean age = 15.41 [SD = 1.65] years, range 12-18; 1465 (43.5%) males and 1905 (56.5%) females) in Brazil, Bulgaria, Croatia, Indonesia, Montenegro, Nigeria, the Palestinian Territories, the Philippines, Romania, and Serbia, with Portugal, a high-income country, as a reference point. The UCLA PTSD Reaction Index for the DSM-5 (PTSD-RI-5) was used for the assessment of traumatic events and PTSD symptoms., Results: The most frequently reported traumatic events were death of a close person (69.7%), witnessing violence other than domestic (40.5%), being in a natural disaster (34.4%) and witnessing violent death or serious injury of a close person (33.9%). In total, 28.5% adolescents endorsed two to three DSM-5 PTSD criteria symptoms. The rates of adolescents with symptoms from all four DSM-5 criteria for PTSD were 6.2-8.1% in Indonesia, Serbia, Bulgaria, and Montenegro, and 9.2-10.5% in Philippines, Croatia and Brazil. From Portugal, 10.7% adolescents fall into this category, while 13.2% and 15.3% for the Palestinian Territories and Nigeria, respectively. A logistic regression model showed that younger age, experiencing war, being forced to have sex, and greater severity of symptoms (persistent avoidance, negative alterations in cognitions and mood, and alterations in arousal and reactivity) were significant predictors of fulfilling full PTSD criteria., Conclusions: Nearly every third adolescent living in LMICs might have some PTSD symptoms after experiencing a traumatic event, while nearly one in ten might have sufficient symptoms for full DSM-5 PTSD diagnosis. The findings can inform the generation of PTSD burden estimates, allocation of health resources, and designing and implementing psychosocial interventions for PTSD in LMICs.

- Abstract
Background: Selecting the optimal treatment strategy for coronary revascularization is challenging. A crucial endpoint to be considered when making this choice is the necessity to repeat revascularization since it is much more frequent after percutaneous coronary intervention (PCI) than after coronary artery bypass grafting (CABG)., Objective: This study intends to provide insights on patients' preferences for revascularization, strategies in the perspective of patients who had to repeat revascularization., Methods: We selected a sample of patients who had undergone PCI and were hospitalized to repeat coronary revascularization and elicited their preferences for a new PCI or CABG. Perioperative death, long-term death, myocardial infarction, and repeat revascularization were used to design scenarios describing hypothetical treatments that were labeled as PCI or CABG. PCI was always presented as the option with lower perioperative death risk and a higher necessity to repeat procedure. A conditional logit model was used to analyze patients' choices using R software. A p value < 0.05 was considered statistically significant., Results: A total of 144 patients participated, most of them (73.7%) preferred CABG over PCI (p < 0.001). The regression coefficients were statistically significant for PCI label, PCI long-term death, CABG perioperative death, CABG long-term death and repeat CABG. The PCI label was the most important parameter (p < 0.05)., Conclusion: Most patients who face the necessity to repeat coronary revascularization reject a new PCI, considering realistic levels of risks and benefits. Incorporating patients' preferences into benefit-risk calculation and treatment recommendations could enhance patient-centered care.

- Abstract
Introduction: Academic detailing (AD) is an effective, evidence-based education outreach method of promoting clinician behavior change. Detailer feedback is important for program evaluation but is rarely systematically collected. The study's objective was to develop a measure capturing the detailer's perception of the effectiveness of an AD program., Methods: A six-item measure with a five-level scale was initially developed from the literature review and expert panel consultation. Item constructs were usefulness, acceptability, feasibility, relevance, effectiveness of communication, and readiness to change. The measure was piloted, refined, and tested during an opioid-focused AD program that included two visits. The instrument structure was evaluated using exploratory factor analysis, measure reliability was assessed using item-item correlation (rho), corrected item-total correlation, Cronbach alpha (α), and item response theory., Results: The initial six-item instrument demonstrated unidimensionality. The Cronbach α for the measure was 0.74 (visit 1) and 0.79 (visit 2); one item (relevance) was redundant (α = 0.73 and 0.79 when deleted) and therefore dropped. Items related to usefulness, acceptability, and readiness to change displayed high item-item correlation (rho ≥ 0.50) and contributed the most information and seemed to operate as a single scale (ie, "likelihood to change") based on item response theory analysis. Items related to feasibility and communication were slightly different constructs and should be reported separately., Discussion: The five-item detailer assessment of visit effectiveness (the "DAVE") instrument provides a standardized approach to assess AD. Further study of its validity and broader use in other programs and educational outreach activities is encouraged.

- Abstract
Background: Information about how individual characteristics influence preferences about health states valuation are scare. The purpose of this study is to identify predictors of the EuroQol with five dimensions and 3 levels - EQ 5D-3L time-tradeoff valuation., Research Design and Methods: We analyzed a dataset with a probabilistic sample of 5774 individuals. Two sets of independent variables for testing were defined: a set of forced variables composed of 10 dummy variables for EuroQol levels 2 and 3 of each health dimension and a set of demographic variables., Results: The strongest predictors of health valuation were the self-reported health state and the 'belief in God,' with 0.11 utility units for each VAS unit and 0.11 utility units for 'yes' for the 'belief in God' parameter.Age had an impact of 0.0190 utility units for each 10-year interval. Having children had a small effect (0.0338 utility units for 'yes'), and the other characteristics studied had no significant impact., Conclusions: People who believe in God (or the afterlife) and those of greater age seem to be less prone to forgoing life years to avoid health problems. In our sample, older individuals valued health state higher than younger individuals.

- Abstract
Background: Value assessment of vaccination programs against serogroup B invasive meningococcal disease (IMD) is on the agenda of public health authorities. Current evidence on the burden due to IMD is unfit for pinning down the nature and magnitude of the full social and economic costs of IMD for two reasons. First, the concepts and components that need to be studied are not agreed, and second, measures of the concepts that have been studied are weak and inconsistent. Thus, the economic evaluation of the available serogroup B meningococcal (MenB) vaccines is difficult. The aims of this DELPHI study are to: (1) agree on the concepts and components determining the burden of MenB diseases that need to be studied; and (2) seek consensus on appropriate methods and study designs to measure quality of life (QoL) associated with MenB induced long-term sequelae in future studies., Methods: We designed a DELPHI questionnaire based on the findings of a recent systematic review on the QoL associated with IMD-induced long-term sequelae, and iteratively interviewed a panel of international experts, including physicians, health economists, and patient representatives. Experts were provided with a controlled feedback based on the results of the previous round., Results: Experts reached consensus on all questions after two DELPHI rounds. Major gaps in the literature relate (i) to the classification of sequelae, which allows differentiation of severity levels, (ii) to the choice of QoL measures, and (iii) to appropriate data sources to examine long-term changes and deficits in patients' QoL., Conclusions: Better conceptualisation of the structure of IMD-specific sequelae and of how their diverse forms of severity might impact the QoL of survivors of IMD as well as their family network and care-providers is needed to generate relevant, reliable and generalisable data on QoL in the future. The results of this DELPHI panel provide useful guidance on how to choose the study design, target population and appropriate QoL measures for future research and hence, help promote the appropriateness and consistency in study methodology and sample characteristics.

- Abstract
Background: Quality of life has become a key outcome in assessing the effectiveness of treatments and interventions in health., Methods: Accordingly, this research study aimed to measure quality of life using the EQ-5D-3L instrument for patients from the Jamil Haddad National Institute of Traumatology and Orthopedics (Instituto Nacional de Traumatologia e Ortopedia Jamil Haddad - INTO) with femoral fractures, hospitalized between 11/2015 and 10/2016., Results: A total of 165 orthopedic trauma patients with femoral fractures, aged 18 years or older, who were hospitalized and operated upon in the INTO were assessed. The assessment instruments were applied at admission and in the first and second follow-up visits to the outpatient clinic. Most study subjects were women and older than 60 years. Proximal femoral fracture was the most commonly found fracture. The Visual Analog Scale (VAS) assessments over the study period showed an increasing gain in self-assessed quality of life. Similarly, the EQ-5D-3L showed significant improvements in quality of life assessed in the five dimensions of the instrument: mobility, self-care, usual activities, pain/discomfort and anxiety/depression., Conclusion: This type of assessment may help in decision-making and cost-utility assessments related to orthopedic trauma.

- Abstract
Purpose: A preference inversion occurs when "worse" health (instead of "better" health) along a scale or score is preferred. Our aim was to confirm past findings of EQ-5D-5L preference inversions among English-speaking respondents and to explore inversions among Portuguese-speaking respondents. Anecdotal evidence suggests that inversions may be more common in the Portuguese version, where the translation of the fourth level "severely" (gravemente) means "gravely.", Methods: Through an infusion clinic in Tampa, Florida, United States and a cardiology clinic in Rio de Janeiro, Brazil, 740 respondents completed a tablet-based survey, which included the EQ-5D-3L and -5L followed by paired comparisons designed to assess preference inversions between the fourth and fifth levels of each of the five domains: Mobility (MO), Self-Care (SC), Usual Activity (UA), Pain/Discomfort (PD), and Anxiety/Depression (AD). An example from the AD dimension would be: "Which do you prefer? Starting today, 30 days with health problems: Severely anxious or depressed or Extremely anxious or depressed" (i.e., Level 4 AD vs. Level 5 AD)., Results: In the English-speaking respondents, preference inversion was only observed to a substantial extent in the AD dimension (U.S. N = 470; 7% MO, 14% SC, 14% UA, 20% PD, and 45% AD). Inversions were more common among the Portuguese-speaking respondents (Brazil N = 270; 11% MO, 32% SC, 35% UA, 49% PD, and 65% AD). Specifically, 44 out of 68 Brazilian respondents (65%) preferred "extremamente" (Level 5 AD) over "gravemente ansioso (a) ou deprimido (a)" (Level 4 AD)., Conclusions: This evidence confirms previous findings for the U.S. English version of the EQ-5D-5L and led to a relabeling on the Portuguese version. It demonstrates the usefulness of collaboration between psychometric, econometric, and linguistic experts in developing the wording for and translating preference-based measures of health-related quality of life. Further research may explore inversions in other translations. The authors recommend that preference inversion tests should be included in the development and translation process.

- Abstract
Background: Most EQ-5D-3L valuation studies include the same sample of health states that was used in the protocol of the original UK Measurement and Valuation of Health (MVH) study. Thus far, no studies using a time tradeoff utility elicitation method have been carried out using all 243 EQ-5D health states. Because the values and preferences regarding health outcomes differ among countries, it is essential to have country-specific data to enable local high-level decisions regarding resource allocation. This study developed a country-specific set of values for EQ-5D-3L health states., Methods: A multicentric study was conducted in 4 Brazilian areas. A probabilistic sample of the general population, aged 18 to 64 y, stratified by age and gender, was surveyed. The interview followed a revised version of the MVH protocol, in which all 243 health states were valued. Each respondent ranked and valued 7 health states using the TTO in a home interview., Results: Data were collected from 9148 subjects. The best-fitting regression model was an individual-level mixed-effects model without any interaction terms. The dimensions "Mobility" and "Usual Activities" were associated with higher losses in health state utility value. The "Anxiety/Depression" dimension was the domain that contributed to lower losses in health state utility value., Conclusions: This study generated significant insight into the Brazilian population's health preferences that can be applied to health technology assessment and economic analyses in Brazil. This information represents an important new tool that can be used in Brazilian health policy creation and evaluation., (© The Author(s) 2015.)

- Abstract
In recent years, charge-tagged ligands (CTLs) have become valuable tools in organometallic catalysis. Insertion of an ionic side chain into the molecular skeleton of a known ligand has become a useful protocol for anchoring ligands, and consequently catalysts, in polar and ionic liquid phases. In addition, the insertion of a cationic moiety into a ligand is a powerful tool that can be used to detect reaction intermediates in organometallic catalysis through electrospray ionisation mass spectrometry (ESI-MS) experiments. The insertion of an ionic tag ensures the charge in the intermediates independently of the ESI-MS. For this reason, these ligands have been used as ionic probes in mechanistic studies for several catalytic reactions. Here, we summarise selected examples on the use of CTLs as immobilising agents in organometallic catalysis and as probes for studying mechanisms through ESI-MS.

- Abstract
Electronic identification of animals has become increasingly important worldwide to improve and ensure traceability. In warm and hot climates, such as Brazil, boluses can have advantages over ear tags as the internal devices reduce the risks of ear tag losses, tissue damage, and lesions on the ear. Electronic boluses, however, are often perceived as having negative characteristics, including reported difficulties of administration in small ruminants. This paper describes the factors associated with bolus design that affect the swallowing of a bolus in sheep. Other factors that might influence bolus swallowing time have also been considered. In addition, the effect of bolus design on its performance was evaluated. A total of 56 Suffolk ewes were used to assess the ease of administration and retention of 3 types of electronic ruminal boluses (mini, 11.5 × 58.0 mm and 21.7 g; small, 14.8 × 48.5 mm and 29.5 g; standard, 19.3 × 69.8 mm and 74.4 g) during a whole productive year, including pregnancy and lamb suckling. Ewe age (5.6 ± 2.3 yr) and weight (85.07 ± 8.2 kg BW) were recorded, as well as time for bolus swallowing. The deglutition of the bolus and any resulting blockages in the esophagus were monitored by visual observations. Retention and readability of the boluses were regularly monitored for d 1, wk 1, mo 1, and every mo until 1 yr. Time for bolus swallowing differed substantially with bolus type and was greater (P < 0.05) for the standard bolus (32.8 ± 6.9 s) when compared to small and mini boluses, which did not differ (8.5 ± 2.0 vs. 9.2 ± 2.7 s; P > 0.05). The bolus o.d. and length were positively correlated with swallowing time (P < 0.01). The ewe weight was negatively correlated with swallowing time (P < 0.05). At 6 mo all electronic boluses showed 100% retention rate, and at 12 mo, bolus retention was 100%, 94.5%, and 100% for mini, small, and standard boluses, respectively (P > 0.05). At 12 mo, all boluses showed 100% readability, except for small boluses, which had a readability of 94.5%. In conclusion, bolus design affected swallowing time and bolus readability. A reduction in boluses length and o.d. needs to be carried out to provide ease of administration and for boluses to be used as an effective means of electronic identification. Therefore, this study shows that adequately designed boluses are safe and suitable for identifying adult sheep and can therefore be used in hot climates.

- Abstract
Objective: HLA-G has well recognized tolerogenic properties in physiological and nonphysiological conditions. The 3' untranslated region (3'UTR) of the HLA-G gene has at least 3 polymorphic sites (14-bpINS/DEL, +3142C/G, and +3196C/G) described as associated with posttranscriptional influence on messenger RNA production; however, only the 14-bpINS/DEL and +3142C/G sites have been studied in systemic lupus erythematosus (SLE)., Methods: We investigated the HLA-G 3'UTR polymorphic sites (14-bpINS/DEL, +3003C/T, +3010C/G, +3027A/C, +3035C/T, +3142C/G, +3187A/G, and +3196C/G) in 190 Brazilian patients with SLE and 282 healthy individuals in allele, genotype, and haplotype analyses. A multiple logistic regression model was used to assess the association of the disease features with the HLA-G 3'UTR haplotypes., Results: Increased frequencies were observed of the 14-bpINS (p = 0.053), +3010C (p = 0.008), +3142G (p = 0.006), and +3187A (p = 0.013) alleles, and increased frequencies of the 14-bpINS-INS (p = 0.094), +3010 C-C (p = 0.033), +3142 G-G (p = 0.021), and +3187 A-A (p = 0.035) genotypes. After Bonferroni correction, only the +3142G (p = 0.05) and +3010C (p = 0.06) alleles were overrepresented in SLE patients. The UTR-1 haplotype (14-bpDEL/+3003T/+3010G/+3027C/+3035C/+3142C/+3187G/+3196C) was underrepresented in SLE (pcorr = 0.035)., Conclusion: These results indicate that HLA-G 3'UTR polymorphic sites, particularly +3142G and +3010C alleles, were associated with SLE susceptibility, whereas UTR-1 was associated with protection against development of SLE.

- Abstract
Nineteen taxa of Mucorales, belonging to Absidia, Apophysomyces, Cunninghamella, Fennellomyces, Lichtheimia, Mucor, Mycotypha, Rhizopus and Syncephalastrum were isolated from 36 composite soil samples in three semiarid areas in the State of Pernambuco (Triunfo, Cabrobó and Belém de São Francisco), Northeast Brazil, which are characterized by Caatinga vegetation. Triunfo is preserved, whereas Cabroró and Belém de São Francisco are experiencing low and severe desertification processes, respectively. Mucorales were isolated in Petri dishes in triplicate from 5 mg samples of soil placed on the surface of wheat germ agar plus chloramphenicol and Cercobin [Dimethyl 4,49-(103 phenylene) bis (3-thioallophanate)] medium. The plates were left on a bench at room temperature (28 ± 2 °C) for 72 h of alternating dark and light periods. Absidia cylindrospora presented the highest amount of CFU/g of soil, followed by L. hyalospora, C. phaeospora and C. echinulata var. echinulata. The latter, and R. microsporus var. microsporus, presented the highest frequencies of occurrence. Soils from Triunfo showed higher diversity of Mucorales than the samples from the other areas, although without differing statistically in relation to species richness. The communities of Mucorales from the degraded areas were more similar, while that from the preserved area was quite different. Most of the identified specimens have been commonly isolated from soil in other Brazilian regions, which indicates that they are not endemic of the semiarid. Eleven taxa are registered for the first time in this ecosystem, while F. heterothallicus is reported for the first time in Brazil.

- Abstract
Dentoalveolar ankylosis is described as the direct union between root cementum/dentin and alveolar bone. Its etiology is unknown, and conflicting opinions have been presented to explain it. Late detection of ankylosed primary teeth may cause serious problems to the occlusion and generally demands a more complex treatment approach. The purpose of this report is to present an unusual case of severe infraocclusion of the primary maxillary right second molar associated with a posterior crossbite in a 6-year-old child. The initial treatment option was tooth extraction, but the tooth resumed eruption spontaneously. After correction of the posterior crossbite and a 1-year follow-up, the tooth remained in occlusion and the permanent successor was developing without problems. From this unusual outcome, it may be concluded that further investigation of this anomaly of eruption is needed.

- Abstract
Sheep and goats are the species of farm animal with the highest growth rate in Paraná State. The main problems facing Paraná State flocks are gastrointestinal parasites and anthelmintic resistance. One of the newest resources used to slow down the development of anthelmintic resistance is the FAMACHA(©) system, a selective method useful for controlling gastrointestinal verminosis in small ruminants. The purpose of the present research was to evaluate the sensitivity and specificity of the FAMACHA(©) system in sheep and goats and to compare the results for both species. The conjunctivae of 83 Suffolk ewes and 60 adult crossbred Boer does were evaluated by the same trained person using the FAMACHA(©) system. The packed cell value (PCV) served as the gold standard for clinical FAMACHA(©) evaluation. To calculate the sensitivity and specificity of the FAMACHA(©) system, different criteria were adopted in turn: animals classified as FAMACHA(©) (F(©)) 4 and 5, or 3, 4 and 5, were considered to be anemic (positive test), and animals classified as F(©)1, 2 and 3, or 1 and 2 were considered to be non-anemic (negative test). Three standard values of PCV, namely ≤19%, ≤18% or ≤15%, were used to confirm anemia. At all cut-off levels, the sensitivity increased if F(©)3 animals were included as being anemic. However, changes in levels of sensitivity were associated with reciprocal changes in specificity. The sensitivity was higher for sheep than for goats, excepting when the criteria included PCV≤18 and F(©)3, F(©)4 and F(©)5 were considered positive. In contrast, the specificity was always lower in sheep for any criteria adopted. Other than in goats, using the ≤15 cut-off level for sheep, it is possible to opt not to drench the animals that were shown to be F(©)3 because the sensitivity is still high, indicating that few animals that should have been drenched were overlooked. In goats, in contrast, the low sensitivity at all cut-off levels made it too risky to leave F(©)3 animals undrenched. Even though the number of correct treatments for goats was always higher than that for sheep, the opposite was true for the kappa index for all the criteria tested. Therefore, the FAMACHA(©) system is suitable for the identification of anemic animals of both species. It is necessary that all small ruminants classified as FAMACHA(©) level 3 are also treated to increase the sensitivity of the method., (Copyright © 2012 Elsevier B.V. All rights reserved.)

- Abstract
An acetate anion bearing an imidazolium cation as its charge tag was reacted with M(OAc)(2) complexes (where M = Ni, Cu, and Pd; in situ reaction) to form members of a new class of charge-tagged metal complexes. The formation of these unprecedented precatalysts with potential for cross-coupling reactions was confirmed by electrospray ionization (and tandem) mass spectrometry. The catalytic performance of the palladium complex was tested in Heck and Suzuki cross-coupling reactions, often with superior activity and yields as compared with Pd(OAc)(2).

- Abstract
Noroviruses (NoVs) are major agents of gastroenteritis outbreaks and hospitalization worldwide. This study evaluated the sensitivity and specificity of the commercially available third-generation RIDASCREEN® Norovirus Enzyme Immunoassay (EIA) kit in comparison to the reverse transcription-polymerase chain reaction (RT-PCR) to detect NoVs in hospitalized children with gastroenteritis. An agreement of 88% (81/92) was observed when comparing EIA with RT-PCR. A sensitivity of 92% and a specificity of 83.3% were demonstrated. Eleven samples were positive by 1 method only (4 RT-PCR/7 EIA). Fourteen samples were sequenced and all classified as NoV genogroup GII-4. The 7 positive only by EIA were also evaluated by electron microscopy, and in 3 (42.9%) samples viral particles with a suggestive morphology of NoVs were visualized. These same samples were tested by seminested-RT-PCR with a positivity of 85.7%. The results obtained in this study demonstrated a significant improvement in the sensitivity and specificity of this updated assay., (Copyright © 2011 Elsevier Inc. All rights reserved.)

de Azevedo Santiago AL, Botelho Trufem SF, Malosso E, Dos Santos PJ, and de Queiroz Cavalcanti MA
- Abstract
Thirty-eight taxa of Zygomycetes distributed in 15 genera were recorded from tapir (Tapirus terrestris), camel (Camelus bactrianus), horse (Equus caballus), deer (Cervus elaphus), agouti (Dasyprocta aguti), donkey (Equus asinus), llama (Llama glama) and waterbuck (Kobus ellipsiprymnus) dung collected at the Reserva Ecológica de Dois Irmãos located in Recife, State of Pernambuco, Northeast Brazil. The samples were collected on a monthly basis from June 2005 to May 2006, taken to the laboratory and incubated in moist chambers. Higher number of taxa was observed in the excrements of tapir, followed by deer and donkey. The highest number of species was detected for Mucor, followed by Pilobolus. Statistical analyses showed significant differences in richness of Zygomycetes taxa between the herbivore dung types. Differences of species composition, however, were weak. Seasonality influenced the Zygomycetes species composition but not its richness. Variations in taxa composition between ruminants and non-ruminants dung were non significant.
