Tendência da mortalidade por câncer do colo do útero no Brasil: 1980 a 2009
The objective was to describe time trends in cervical cancer mortality rates in Brazil as a whole and in the country's major geographic regions and States from 1980 to 2009. This was an ecological time series study using data recorded in the Mortality Information System (SIM) and census data collected by the Brazilian Institute of Geography and Statistics (IBGE). Analysis of mortality trends was performed using Poisson regression. Cervical cancer mortality rates in Brazil tended to stabilize. In the geographic regions, a downward trend was observed in the South (-4.1%), Southeast (-3.3%), and Central-West (-1%) and an upward trend in the Northeast (3.5%) and North (2.7%). The largest decreases were observed in the States of São Paulo (5.1%), Rio Grande do Sul, Espírito Santo, and Paraná (-4.0%). The largest increases in mortality trends occurred in Paraíba (12.4%), Maranhão (9.8%), and Tocantins (8.9%). Cervical cancer mortality rates stabilized in the country as a whole, but there was a downward trend in three geographic regions and 10 States, while two geographic regions and another 10 States showed increasing rates.El objetivo fue analizar la mortalidad por cáncer de cuello de útero en Brasil, en sus macrorregiones y estados en el período de 1980 a 2009. Se trata de un estudio ecológico de serie temporal, con uso de información sobre óbitos del Sistema de Información sobre Mortalidad (SIM), y base demográfica del Instituto Brasileño de Geografía y Estadística (IBGE). Se realizaron análisis de las tendencias de la mortalidad, mediante la regresión de Poisson. En Brasil se observó la estabilización en las tasas de mortalidad. En las macrorregiones, hubo caída en el Sur (-4,1%), Sudeste (-3,3%) y Centro-Oeste (-1%); aumento en el Nordeste (3,5%) y Norte (2,7%). En los estados, las principales caídas fueron observadas en São Paulo (-5,1%), Rio Grande do Sul, Espírito Santo y Paraná (-4%). Los mayores aumentos se observaron en Paraíba (12,4%), Maranhão (9,8%) y Tocantins (8,9%). Conclusión: Brasil presenta estabilización en las tasas de mortalidad. No obstante, hubo una reducción en 3 macrorregiones y en 10 estados, mientras que en 2 macrorregiones y en 10 estados la mortalidad sigue aumentando. Una de las razones para esa disparidad puede ser el menor acceso al tratamiento para las pacientes de áreas menos desarrolladas.O objetivo deste estudo foi fornecer um quadro quanto à tendência da mortalidade por câncer do colo de útero no Brasil, em suas regiões e estados, entre 1980 e 2009.

Eficácia do treinamento da musculatura do assoalho pélvico e de exercícios hipopressivos para o tratamento do prolapso de órgãos pélvicos em mulheres: ensaio clínico randomizado
CONTEXT AND OBJECTIVE: Previous studies have shown that women with pelvic floor dysfunctions present decreased cross-sectional area (CSA) of the levator ani muscle. One way to assess the effects of training programs is to measure the CSA of the muscle, using ultrasonography. The aim here was to evaluate the efficacy of pelvic floor muscle training and hypopressive exercises for increasing the CSA of the levator ani muscle in women with pelvic organ prolapse. DESIGN AND SETTING: Prospective randomized controlled trial at the Urogynecology outpatient clinic of Universidade Federal de São Paulo (UNIFESP). METHODS: Fifty-eight women with stage II pelvic organ prolapse were divided into three groups for physiotherapy: a pelvic floor muscle training group (GI); a hypopressive exercise group (GII); and a control group (GIII). The patients underwent transperineal ultrasonographic evaluation using a transducer of frequency 4-9 MHz. The (CSA) of the levator ani muscle was measured before physiotherapy and after 12 weeks of treatment. RESULTS: The groups were homogeneous regarding age, number of pregnancies, number of vaginal deliveries, body mass index and hormonal status. Statistically significant differences in CSA were found in GI and GII from before to after the treatment (P < 0.001), but not in relation to GIII (P = 0.816). CONCLUSIONS: The CSA of the levator ani muscle increased significantly with physiotherapy among the women with pelvic organ prolapse. Pelvic floor muscle training and hypopressive exercises produced similar improvements in the CSA of the levator ani muscle.CONTEXTO E OBJETIVO: Estudos anteriores mostraram que mulheres com disfunção do assoalho pélvico possuem diminuição da área de secção transversal (AST) do músculo levantador do ânus. Uma forma de avaliar os efeitos de um programa de treinamento é mensurar a AST do músculo por ultrassonografia. O objetivo foi avaliar a eficácia do treinamento da musculatura do assoalho pélvico e de exercícios hipopressivos no aumento da AST do músculo levantador do ânus em mulheres com prolapso de órgãos pélvicos. TIPO DE ESTUDO E LOCAL: Estudo prospectivo, randomizado e controlado realizado no Ambulatório de Uroginecologia da Universidade Federal de São Paulo (UNIFESP). MÉTODOS: Cinquenta e oito mulheres com prolapso de órgãos pélvicos estádio II foram divididas em três grupos para tratamento fisioterapêutico: (GI) grupo de treinamento dos músculos do assoalho pélvico, (GII) grupo de exercícios hipopressivos e (GIII) grupo controle. As pacientes se submeteram a avaliação ultrassonográfica transperineal com transdutor de frequência 4-9 MHz. Foi mensurada a AST do músculo levantador do ânus antes e após 12 semanas de tratamento fisioterapêutico. RESULTADOS: Os grupos foram homogêneos no que se refere a idade, número de gestações, número de partos vaginais, índice de massa corpórea e estado hormonal. Diferença significante foi observada na AST de GI e GII antes e após o tratamento (P < 0,001) e isso não ocorreu com o GIII (P = 0,816). CONCLUSÕES: A AST do músculo levantador do ânus aumentou significativamente com tratamento fisioterapêutico em mulheres com prolapso de órgãos pélvicos. Treinamento dos músculos do assoalho pélvico e exercícios hipopressivos são semelhantes no que se refere ao aumento da AST do músculo levantador do ânus.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Universidade Federal de São Paulo (UNIFESP) Department of GynecologyUniversidade Federal de Uberlândia Department of Gynecology and ObstetricsUNIFESP, Department of GynecologyFAPESP: 2007/08246-8SciEL

However, we still lack the ability to fully control the epigenetic status of iPSCs, which is a major hurdle for their downstream applications. Epigenetic fidelity can be tracked by genomic imprinting, a phenomenon dependent on DNA methylation, which is frequently perturbed in iPSCs by yet unknown reasons. To try to understand the causes underlying these defects, we conducted a thorough imprinting analysis using IMPLICON, a high-throughput method measuring DNA methylation levels, in multiple female and male murine iPSC lines generated under different experimental conditions. Our results show that imprinting defects are remarkably common in iPSCs, but their nature depends on the sex of donor cells and their response to culture conditions. Imprints in female iPSCs resist the initial genome-wide DNA demethylation wave during reprogramming, but ultimately cells accumulate hypomethylation defects irrespective of culture medium formulations. In contrast, imprinting defects on male iPSCs depends on the experimental conditions and arise during reprogramming, being mitigated by the addition of vitamin C (VitC). Our findings are fundamental to further optimise reprogramming strategies and generate iPSCs with a stable epigenome.publishersversionpublishe
Portuguese recommendations for the use of biological and targeted synthetic diseasemodifying antirheumatic drugs in patients with rheumatoid arthritis – 2020 update
Objective: To update the recommendations for the treatment of rheumatoid arthritis (RA) with biological and targeted synthetic disease-modifying antirheumatic drugs (bDMARDs and tsDMARDs), endorsed by the Portuguese Society of Rheumatology (SPR).
Methods: These treatment recommendations were formulated by Portuguese rheumatologists taking into account previous recommendations, new literature evidence and consensus opinion. At a national meeting, in a virtual format, three of the ten previous recommendations were re-addressed and discussed after a more focused literature review. A first draft of the updated recommendations was elaborated by a team of SPR rheumatologists from the SPR rheumatoid arthritis study group, GEAR. The resulting document circulated among all SPR rheumatologists for discussion and input. The level of agreement with each of all the recommendations was anonymously voted online by all SPR rheumatologists.
Results: These recommendations cover general aspects such as shared decision, treatment objectives, systematic assessment of disease activity and burden and its registry in Reuma.pt. Consensus was also achieved regarding specific aspects such as initiation of bDMARDs and tsDMARDs, assessment of treatment response, switching and definition of persistent remission.
Conclusion: These recommendations may be used for guidance of treatment with bDMARDs and tsDMARDs in patients with RA. As more evidence becomes available and more therapies are licensed, these recommendations will be updated.info:eu-repo/semantics/publishedVersio
Efficacy of pelvic floor muscle training and hypopressive exercises for treating pelvic organ prolapse in women: randomized controlled trial
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

Search for supersymmetry in proton-proton collisions at 13 TeV using identified top quarks
A search for supersymmetry is presented based on proton-proton collision events containing identified hadronically decaying top quarks, no leptons, and an imbalance p(T)(miss) in transverse momentum. The data were collected with the CMS detector at the CERN LHC at a center-of-mass energy of 13 TeV, and correspond to an integrated luminosity of 35.9 fb(-1). Search regions are defined in terms of the multiplicity of bottom quark jet and top quark candidates, the p(T)(miss) , the scalar sum of jet transverse momenta, and themT2 mass variable. No statistically significant excess of events is observed relative to the expectation from the standard model. Lower limits on the masses of supersymmetric particles are determined at 95% confidence level in the context of simplified models with top quark production. For a model with direct top squark pair production followed by the decay of each top squark to a top quark and a neutralino, top squark masses up to 1020 GeVand neutralino masses up to 430 GeVare excluded. For amodel with pair production of gluinos followed by the decay of each gluino to a top quark-antiquark pair and a neutralino, gluino masses up to 2040 GeVand neutralino masses up to 1150 GeVare excluded. These limits extend previous results.Peer reviewe
