Assessment of knowledge toward periodontal disease among a sample of nephrologists and nurses who work with chronic kidney disease not yet on dialysis

INTRODUCTION: Recent studies have identified periodontal disease (PD) as a risk factor for chronic kidney disease (CKD). The aim of this study was to assess the general knowledge about, attitudes toward, and behaviors/practices concerning PD among physicians and nurses who work with CKD patients. METHODS: An 8-question questionnaire was distributed to participants of the XXV Brazilian Congress of Nephrology (2010) and the Minas Gerais Nephrology Congress (2011). The questions covered the following aspects of PD: epidemiology, clinical presentation, predisposing factors, systemic expression, inclusion of oral examination during routine physical examination, and the frequency of referral for dental treatment. RESULTS: Most physicians and nurses interviewed correctly answered the questions on general knowledge about PD. 42.2% of the physicians and 38% of the nurses did not routinely examine the oral cavity of their patients. Most patients seen by nephrologists (59.4%) and nurses (61.5%) were referred to dental care in less than 30% of the consultations. CONCLUSION: Nephrologists and nurses demonstrated good self-reported general knowledge about PD, albeit with limited clinical experience, as evidenced by the low rates of examination of the oral cavity and referral for specialist treatment. These findings suggest the need of theoretical and practical training in oral health at both, undergraduate (medicine and nursing) and postgraduate levels (medical and multiprofessional residency programs).INTRODUÇÃO: estudos recentes apontam a doença periodontal (DP) como fator de risco para doença renal crônica (DRC). O objetivo do presente estudo foi avaliar o grau de conhecimento, atitude e prática de médicos e enfermeiros que atuam na nefrologia relativos à DP. MÉTODOS: um questionário foi aplicado a médicos e a enfermeiros participantes do XXV Congresso Brasileiro de Nefrologia (2010) e IX Congresso Mineiro de Nefrologia (2011), abrangendo os seguintes aspectos da DP: epidemiologia, apresentação clínica, fatores predisponentes, repercussão sistêmica, a inclusão do exame da cavidade bucal no exame clínico dos pacientes com DRC e a frequência de encaminhamento para o dentista. RESULTADOS: a maioria dos médicos e enfermeiros responderam corretamente às perguntas que abordaram os conhecimentos gerais sobre a DP. À pergunta referente à inclusão do exame da cavidade bucal no exame físico do paciente, 42,2% dos médicos e 38% dos enfermeiros responderam não fazê-la (p > 0,05). Contudo, a maioria dos pacientes vistos por nefrologistas (59,4%) e enfermeiros (61,8%) são encaminhados ao dentista em menos de 30% das consultas (p > 0,05). CONCLUSÃO: A amostra de nefrologistas e de profissionais de enfermagem participantes do estudo demonstrou conhecimento autorrelatado sobre DP considerado bom, embora com prática clínica limitada, expressada pelo baixo percentual de encaminhamento para tratamento especializado da doença. Os achados sinalizam para a necessidade da instituição de treinamento teórico-prático em saúde bucal nos cursos de graduação (medicina e enfermagem) e pós-graduação (residência médica e multiprofissional).Núcleo Interdisciplinar de Estudos, Pesquisas e Tratamento em NefrologiaUniversidade Federal de Juiz de Fora Faculdade de OdontologiaUFJF Faculdade de Educação FísicaUFJF Faculdade de EnfermagemUFJF Faculdade de Odontologia Departamento de Clínicas OdontológicasUniversidade Federal de São Paulo (UNIFESP) NIEPENUNIFESP, NIEPENSciEL

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

MUSiC : a model-unspecific search for new physics in proton-proton collisions at root s=13TeV

Results of the Model Unspecific Search in CMS (MUSiC), using proton-proton collision data recorded at the LHC at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb(-1), are presented. The MUSiC analysis searches for anomalies that could be signatures of physics beyond the standard model. The analysis is based on the comparison of observed data with the standard model prediction, as determined from simulation, in several hundred final states and multiple kinematic distributions. Events containing at least one electron or muon are classified based on their final state topology, and an automated search algorithm surveys the observed data for deviations from the prediction. The sensitivity of the search is validated using multiple methods. No significant deviations from the predictions have been observed. For a wide range of final state topologies, agreement is found between the data and the standard model simulation. This analysis complements dedicated search analyses by significantly expanding the range of final states covered using a model independent approach with the largest data set to date to probe phase space regions beyond the reach of previous general searches.Peer reviewe

Search for new particles in events with energetic jets and large missing transverse momentum in proton-proton collisions at root s=13 TeV

A search is presented for new particles produced at the LHC in proton-proton collisions at root s = 13 TeV, using events with energetic jets and large missing transverse momentum. The analysis is based on a data sample corresponding to an integrated luminosity of 101 fb(-1), collected in 2017-2018 with the CMS detector. Machine learning techniques are used to define separate categories for events with narrow jets from initial-state radiation and events with large-radius jets consistent with a hadronic decay of a W or Z boson. A statistical combination is made with an earlier search based on a data sample of 36 fb(-1), collected in 2016. No significant excess of events is observed with respect to the standard model background expectation determined from control samples in data. The results are interpreted in terms of limits on the branching fraction of an invisible decay of the Higgs boson, as well as constraints on simplified models of dark matter, on first-generation scalar leptoquarks decaying to quarks and neutrinos, and on models with large extra dimensions. Several of the new limits, specifically for spin-1 dark matter mediators, pseudoscalar mediators, colored mediators, and leptoquarks, are the most restrictive to date.Peer reviewe

Measurement of prompt open-charm production cross sections in proton-proton collisions at root s=13 TeV

The production cross sections for prompt open-charm mesons in proton-proton collisions at a center-of-mass energy of 13TeV are reported. The measurement is performed using a data sample collected by the CMS experiment corresponding to an integrated luminosity of 29 nb(-1). The differential production cross sections of the D*(+/-), D-+/-, and D-0 ((D) over bar (0)) mesons are presented in ranges of transverse momentum and pseudorapidity 4 < p(T) < 100 GeV and vertical bar eta vertical bar < 2.1, respectively. The results are compared to several theoretical calculations and to previous measurements.Peer reviewe

Combined searches for the production of supersymmetric top quark partners in proton-proton collisions at root s=13 TeV

A combination of searches for top squark pair production using proton-proton collision data at a center-of-mass energy of 13 TeV at the CERN LHC, corresponding to an integrated luminosity of 137 fb(-1) collected by the CMS experiment, is presented. Signatures with at least 2 jets and large missing transverse momentum are categorized into events with 0, 1, or 2 leptons. New results for regions of parameter space where the kinematical properties of top squark pair production and top quark pair production are very similar are presented. Depending on themodel, the combined result excludes a top squarkmass up to 1325 GeV for amassless neutralino, and a neutralinomass up to 700 GeV for a top squarkmass of 1150 GeV. Top squarks with masses from 145 to 295 GeV, for neutralino masses from 0 to 100 GeV, with a mass difference between the top squark and the neutralino in a window of 30 GeV around the mass of the top quark, are excluded for the first time with CMS data. The results of theses searches are also interpreted in an alternative signal model of dark matter production via a spin-0 mediator in association with a top quark pair. Upper limits are set on the cross section for mediator particle masses of up to 420 GeV

Development and validation of HERWIG 7 tunes from CMS underlying-event measurements

This paper presents new sets of parameters (“tunes”) for the underlying-event model of the HERWIG7 event generator. These parameters control the description of multiple-parton interactions (MPI) and colour reconnection in HERWIG7, and are obtained from a fit to minimum-bias data collected by the CMS experiment at s=0.9, 7, and 13Te. The tunes are based on the NNPDF 3.1 next-to-next-to-leading-order parton distribution function (PDF) set for the parton shower, and either a leading-order or next-to-next-to-leading-order PDF set for the simulation of MPI and the beam remnants. Predictions utilizing the tunes are produced for event shape observables in electron-positron collisions, and for minimum-bias, inclusive jet, top quark pair, and Z and W boson events in proton-proton collisions, and are compared with data. Each of the new tunes describes the data at a reasonable level, and the tunes using a leading-order PDF for the simulation of MPI provide the best description of the dat
