Aborto inseguro: determinantes sociais e iniquidades em saúde em uma população vulnerável, São Paulo, Brasil

This cross-sectional population-based study in a peripheral low-income community in São Paulo, Brazil, aimed to estimate the prevalence of unsafe abortion and identify the socio-demographic characteristics associated with it and its morbidity. The article discusses the study's results, based on univariate and multiple multinomial logistic regression analyses. The final regression models included: age at first intercourse 2 sex partners in the previous year (OR = 3.63); more live born children than the woman's self-reported ideal number (OR = 3.09); acceptance of the abortion due to insufficient economic conditions (OR = 4.07); black ethnicity/color (OR = 2.67); and low schooling (OR = 2.46), all with p 2 (OR = 3,63); número de filhos nascidos vivos > ideal (OR = 3,09); aceitação do aborto por falta de condições econômicas (OR = 4,07); etnia negra/cor preta (OR = 2,67); e escolaridade baixa (OR = 2,46), todos com p < 0,05. Foi utilizada na discussão uma abordagem voltada aos determinantes sociais da saúde, segundo conceito e modelo adotados pela WHO, e às iniquidades em saúde por esses geradas na ocorrência do aborto inseguro. Verificou-se que o aborto inseguro e características sociodemográficas são influenciados pelos determinantes sociais da saúde descritos, gerando nessa população iniquidades em saúde de proporções diversas.Universidade Federal de São Paulo (UNIFESP)UNIFESPSciEL

Ab initio many-body calculation of excitons in solid Ne and Ar

Absorption spectra, exciton energy levels and wave functions for solid Ne and Ar have been calculated from first principles using many-body techniques. Electronic band structures of Ne and Ar were calculated using the GW approximation. Exciton states were calculated by diagonalizing an exciton Hamiltonian derived from the particle-hole Green function, whose equation of motion is the Bethe-Salpeter equation. Singlet and triplet exciton series up to n=5 for Ne and n=3 for Ar were obtained. Binding energies and longitudinal-transverse splittings of n=1 excitons are in excellent agreement with experiment. Plots of correlated electron-hole wave functions show that the electron-hole complex is delocalised over roughly 7 a.u. in solid Ar.Comment: 6 page

Future GW detector networks and EM observatories will provide a unique opportunity to observe the most luminous events in the Universe involving matter in extreme environs. They will address some of the key questions in physics and astronomy: formation and evolution of compact binaries, sites of formation of heavy elements and the physics of jets.Comment: 11 pages, two tables, White Paper submitted to the Astro-2020 (2020 Astronomy and Astrophysics Decadal Survey) by GWIC-3G Science Case Team (GWIC: Gravitational-Wave International Committee

Experimental joint signal-idler quasi-distributions and photon-number statistics for mesoscopic twin beams

Joint signal-idler photoelectron distributions of twin beams containing several tens of photons per mode have been measured recently. Exploiting a microscopic quantum theory for joint quasi-distributions in parametric down-conversion developed earlier we characterize properties of twin beams in terms of quasi-distributions using experimental data. Negative values as well as oscillating behaviour in quantum region are characteristic for the subsequently determined joint signal-idler quasi-distributions of integrated intensities. Also the conditional and difference photon-number distributions are shown to be sub-Poissonian and sub-shot-noise, respectively.Comment: 7 pages, 6 figure

Prevalência e características sociodemográficas de mulheres com aborto provocado em uma amostra da população da cidade de São Paulo, Brasil

Objectives:This study aims at estimating the prevalence of women with induced abortion among women of childbearing age (15-49 years) who had any previous pregnancy, in the city of São Paulo, Brazil, in the last quarter of 2008, and identifying the sociodemographic characteristics (SC) associated with it. Methods:A cross-sectional survey was carried out. The dependent variable was dichotomized as: no abortion and induced abortion. The independent variables were: age, paid work/activity, familial monthly income, schooling, marital status, contraceptive use and number of live births. Statistical analysis was performed using log-binomial regression models with approximation of Poisson to estimate the prevalance ratios (PR). Results:Of all women with any previous pregnancy (n = 683), 4.5% (n = 31) reported induced abortion. The final multivariate model showed that having now between 40 and 44 years (PR = 2.76, p = 0.0043), being single (PR = 2.79, p = 0.0159), having 5 or more live births (PR = 3.97, p = 0.0013), current oral contraception or IUD use (PR = 2.70, p = 0.454) and using a non effective (or of low efficacy) contraceptive method (PR = 4.18, p = 0.0009) were sociodemographic characteristics associated with induced abortion in this population. Conclusions:Induced abortion seems to be used to limit fertility, more precisely after having reached the desired number of children. The inadequate use or non-use of effective contraceptive methods, and / or the use of contraceptivenon effective, exposed also the women to the risk of unintended pregnancies and, therefore, induced abortions. In addition, when faced with a pregnancy, single women were more likely to have an abortion than married women.Objetivos:O presente estudo busca estimar a prevalência de mulheres com aborto provocado dentre as mulheres em idade fértil (15 a 49 anos de idade) que apresentaram alguma gestação prévia, residentes na cidade de São Paulo, Brasil, no último trimestre de 2008, bem como identificar essa ocorrência em função de algumas características sociodemográficas (CSD).Métodos:Trata-se de um estudo transversal. A variável dependente aborto foi dicotomizada em: aborto provocado (AP) e nenhum aborto (NA). As variáveis independentes utilizadas foram: idade, atividade remunerada, renda mensal familiar, escolaridade, estado conjugal, uso de método(s) contraceptivo(s) e número de filhos nascidos vivos. A análise estatística foi realizada por meio de modelos de regressão log-binomial com aproximação de Poisson para avaliar as razões de prevalência (RP).Resultados:Dentre o total de mulheres com alguma gestação prévia (n = 683), 4,5% (n = 31) declararam algum AP. O modelo log-binomial final mostrou que idade atual entre 40 e 44 anos de idade (RP = 2,76; p = 0,0043), estado conjugal solteira (RP = 2,79; p = 0,0159), número de filhos nascidos vivos igual ou maior que 5 (RP = 3,97; p = 0,0013, uso de contraceptivo não eficaz ou de baixa eficácia (RP = 4,18; p = 0,0009) e uso atual de contraceptivo oral ou dispositivo intrauterino (RP = 2,70; p = 0,454) foram as características que se apresentaram mais fortemente associadas à ocorrência de AP entre as mulheres dessa população.Conclusões:O aborto provocado é utilizado para limitar a fecundidade, mais precisamente após atingir-se o número desejado de filhos. O uso inadequado, ou o não-uso, de contraceptivos eficazes e/ou a utilização de contraceptivos não eficazes, ou de baixa eficácia, também promovem a resolução pelo aborto, assim como o fato de as mulheres solteiras enfrentarem uma gestação sozinhas.Universidade Federal de São Paulo (UNIFESP) Department of Preventive MedicineCentro Universitário de GuaxupéUNIFESP, Department of Preventive MedicineSciEL

Ab initio Molecular Dynamics in Adaptive Coordinates

We present a new formulation of ab initio molecular dynamics which exploits the efficiency of plane waves in adaptive curvilinear coordinates, and thus provides an accurate treatment of first-row elements. The method is used to perform a molecular dynamics simulation of the CO_2 molecule, and allows to reproduce detailed features of its vibrational spectrum such as the splitting of the Raman sigma+_g mode caused by Fermi resonance. This new approach opens the way to highly accurate ab initio simulations of organic compounds.Comment: 11 pages, 3 PostScript figure

Sailing as Stroke Rehabilitation Strategy

Stroke (brain attack), is a serious global public health problem and the main cause of many forms of disability. The majority of stroke survivors are mostly left with motor (muscle movement or mobility) impairments. Although remarkable developments have been made in drug treatment, post-stroke care continues to rely on rehabilitation interventions mostly. On the other hand, the presence of post-stroke depression has been associated with decreases in functional recovery, social activity and cognition. Therefore, this project aims to improve the quality of people’s lives after a stroke by introducing sailing as outdoor mobility rehabilitation. It is intended to increase the patients’ motivation and engagement in the rehabilitation process by a more enjoyable and relaxing intervention than the existing ones especially for long term periods. The project, based on a haptic system installed on the deck of NYTEC 28 sailing boat, aim to monitoring rehab process development in post-stroke during normal sailing activity

Women and Illegal Activities: Gender Differences and Women's Willingness to Comply Over Time

In recent years the topics of illegal activities such as corruption or tax evasion have attracted a great deal of attention. However, there is still a lack of substantial empirical evidence about the determinants of compliance. The aim of this paper is to investigate empirically whether women are more willing to be compliant than men and whether we observe (among women and in general) differences in attitudes among similar age groups in different time periods (cohort effect) or changing attitudes of the same cohorts over time (age effect) using data from eight Western European countries from the World Values Survey and the European Values Survey that span the period from 1981 to 1999. The results reveal higher willingness to comply among women and an age rather than a cohort effect. Working Paper 06-5

Prediction of metabolic and cardiopulmonary responses to maximum cycle ergometry: a randomised study

All of the most widely-cited studies for the prediction of maximum exercise responses have utilized either volunteers or referred subjects. Therefore, selection bias, with overestimation of the reference values, is a likely consequence.In order to establish a set of predictive equations for the gas exchange, ventilatory and cardiovascular responses to maximum ramp-incremental cycle ergometry, this study prospectively evaluated 120 sedentary individuals (60 males, 60 females, aged 20-80), randomly-selected from >8,000 subjects. Regular physical activity pattern by questionnaire, body composition by anthropometry and dual energy X-ray absorptiometry (n=75) and knee strength by isokinetic dynamometry were also assessed.Previously reported equations typically overestimated the subjects' peak oxygen uptake (p<0.05). Prediction linear equations for the main variables of clinical interest were established by backward stepwise regression analysis including: sex, age, knee extensor peak torque, bone-free lean leg mass, total and lean body mass, height, and physical activity scares. Reference intervals (95% confidence limits) were calculated: some of these values differed markedly from those formerly recommended.The results therefore might provide a more appropriate frame of reference for interpretation of the responses to symptom-limited ramp incremental cycle ergometry in sedentary subjects; i.e. those usually referred tor clinical cardiopulmonary exercise tests.Universidade Federal de São Paulo, EMP, Dept Med, Div Resp, BR-04023062 São Paulo, BrazilUniversidade Federal de São Paulo, EMP, Multidisciplinary Grp Clin Epidemiol, BR-04023062 São Paulo, BrazilUniversidade Federal de São Paulo, EMP, Dept Prevent & Social Med, BR-04023062 São Paulo, BrazilUniversidade Federal de São Paulo, EMP, Dept Physiol, BR-04023062 São Paulo, BrazilSt Georges Hosp, Sch Med, Dept Physiol, London, EnglandUniv London, London, EnglandUniversidade Federal de São Paulo, EMP, Dept Med, Div Resp, BR-04023062 São Paulo, BrazilUniversidade Federal de São Paulo, EMP, Multidisciplinary Grp Clin Epidemiol, BR-04023062 São Paulo, BrazilUniversidade Federal de São Paulo, EMP, Dept Prevent & Social Med, BR-04023062 São Paulo, BrazilUniversidade Federal de São Paulo, EMP, Dept Physiol, BR-04023062 São Paulo, BrazilWeb of Scienc

Low-temperature structural model of hcp solid C70_{70}

We report intermolecular potential-energy calculations for solid C_${70}$ and determine the optimum static orientations of the molecules at low temperature; we find them to be consistent with the monoclinic structural model proposed by us in an earlier report [Solid State Commun. {\bf 105), 247 (1998)]. This model indicates that the C_5 axis of the molecule is tilted by an angle $\approx$18^o from the monoclinic b axis in contrast with the molecular orientation proposed by Verheijen {\it et al.} [J. Chem. Phys. {\bf 166}, 287 (1992)] where the C_5 axis is parallel to the monoclinic b axis. In this calculation we have incorporated the effective bond charge Coulomb potential together with the Lennard-Jones potential between the molecule at the origin of the monoclinic unit cell and its six nearest neighbours, three above and three below. The minimum energy configuration for the molecular orientations turns out to be at $\theta$=18^o, $\phi$=8^o, and $\psi$=5^o, where $\theta$, $\phi$, and $\psi$ define the molecular orientations.Comment: ReVTeX (4 pages) + 2 PostScript figure
