Síndrome de Sampson: Sampson Syndrome

Introdução: a endometriose é uma doença que acomete, principalmente, mulheres em idade fértil entre 20-30 anos, caracterizada por presença de tecido endometrial nas cavidades, tecidos e órgãos extrauterinos, que cursam com sintomatologia principal: dor pélvica e/ou infertilidade. Apresentação do caso: paciente com 23 anos, sexo feminino, com desejo de engravidar, cessou o uso de contraceptivos há 12 meses. Em consulta ginecológica, refere que vem apresentando quadro de dor.  Discussão: Há manifestações assintomáticas ou oligossintomáticas, a depender do grau de acometimento bem como localização de tecido endometrial ectópico. As lesões da síndrome de Sampson costumam ser bem pequenas e dispersas, exames de ressonância magnética ou ultrassonografia costumam ser inconclusivos para esse tipo de endometriose, pois os nódulos geralmente apresentam-se como imagens sólidas, hipoecogênicas e irregulares. Desse modo, por se tratar de lesões extremamente pequenas, exames de imagem podem não ser eficazes em sua detecção. Conclusão: A etiologia da doença ainda é desconhecida, entretanto existem algumas hipóteses como metaplasia celômica, remanescentes embrionários e menstruação retrógrada

Síndrome de malformação cavernomatosa múltipla familiar: Familial multiple cavernomatous malformation syndrome

Introdução: A Síndrome da má formação cavernomatosa múltipla familiar ocorre principalmente em adultos jovens, e é encontrada no sistema nervoso, com predominância no encéfalo. As cavernomas são lesões raras de malformações vasculares do sistema nervoso central, podendo acometer igualmente indivíduos de ambos os sexos, embora sejam mais comuns em pacientes na terceira e quinta década de vida. Apresentação do caso: Paciente com 36 anos, do sexo feminino, admitida no Pronto Atendimento Municipal de Pindamonhangaba, após episódio de cefaleia de forte intensidade e crise convulsiva tônico-clônica generalizada. A paciente apresentou exame neurológico normal a não ser pelo déficit focal no membro superior direito. Foi realizado procedimento cirúrgico para exérese de lesões e também tecidos anormais adjacentes. Discussão: Existem pacientes assintomáticos e os que apresentam queixas, sendo as mais comuns, a depender do local de acometimento, tamanho e extensão de sangramento, a cefaleia, crise convulsiva e/ou déficit focal. A síndrome se mostrava como uma má formação cerebrovascular oculta e desconhecida, mas com a evolução dos exames de imagem foi possível realizar um melhor diagnóstico e avaliar as características da comorbidade. A Ressonância Nuclear Magnética é considerada o exame padrão-ouro para diagnóstico. Conclusão: A patologia possui origem hereditária em 30-40% dos casos, associada a mutação que leva a perda de função do gene KRIT1 (CCM1), malcavernin (CCM2) e PDC10 (CCM3). Torna-se aconselhável a observação clínica do paciente, e estratégias para controle dos sinais e sintomas. Em casos de lesões profundas no córtex e em locais, indica-se a radiocirurgia na tentativa de interromper a progressão da doença

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

Particle-flow reconstruction and global event description with the CMS detector

The CMS apparatus was identified, a few years before the start of the LHC operation at CERN, to feature properties well suited to particle-flow (PF) reconstruction: a highly-segmented tracker, a fine-grained electromagnetic calorimeter, a hermetic hadron calorimeter, a strong magnetic field, and an excellent muon spectrometer. A fully-fledged PF reconstruction algorithm tuned to the CMS detector was therefore developed and has been consistently used in physics analyses for the first time at a hadron collider. For each collision, the comprehensive list of final-state particles identified and reconstructed by the algorithm provides a global event description that leads to unprecedented CMS performance for jet and hadronic tau decay reconstruction, missing transverse momentum determination, and electron and muon identification. This approach also allows particles from pileup interactions to be identified and enables efficient pileup mitigation methods. The data collected by CMS at a centre-of-mass energy of 8 TeV show excellent agreement with the simulation and confirm the superior PF performance at least up to an average of 20 pileup interactions

Optimasi Portofolio Resiko Menggunakan Model Markowitz MVO Dikaitkan dengan Keterbatasan Manusia dalam Memprediksi Masa Depan dalam Perspektif Al-Qur`an

Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis

Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.

Juxtaposing BTE and ATE – on the role of the European insurance industry in funding civil litigation

One of the ways in which legal services are financed, and indeed shaped, is through private insurance arrangement. Two contrasting types of legal expenses insurance contracts (LEI) seem to dominate in Europe: before the event (BTE) and after the event (ATE) legal expenses insurance. Notwithstanding institutional differences between different legal systems, BTE and ATE insurance arrangements may be instrumental if government policy is geared towards strengthening a market-oriented system of financing access to justice for individuals and business. At the same time, emphasizing the role of a private industry as a keeper of the gates to justice raises issues of accountability and transparency, not readily reconcilable with demands of competition. Moreover, multiple actors (clients, lawyers, courts, insurers) are involved, causing behavioural dynamics which are not easily predicted or influenced. Against this background, this paper looks into BTE and ATE arrangements by analysing the particularities of BTE and ATE arrangements currently available in some European jurisdictions and by painting a picture of their respective markets and legal contexts. This allows for some reflection on the performance of BTE and ATE providers as both financiers and keepers. Two issues emerge from the analysis that are worthy of some further reflection. Firstly, there is the problematic long-term sustainability of some ATE products. Secondly, the challenges faced by policymakers that would like to nudge consumers into voluntarily taking out BTE LEI
