    PURPOSE:To assess the prevalence of Climacteric Syndrome (CS) in women from a municipality of Northeastern Brazil which is less developed socioeconomically.METHODS:A prospective household survey was performed in S&#227;o Lu&#237;s, Maranh&#227;o, Brazil with 1,210 climacteric women aged 45 to 60 years. Interviews were applied using previously tested standard questionnaires from April to July 2008. The severity of climacteric symptoms was analyzed by circulatory and psychological indexes and the latter were associated with menopausal status. Multiple correspondence analysis was used to assess the relation among climacteric symptoms.RESULTS:Most patients were 55 to 60 years old (35.3%), mulatto (37.9%), with 9-11 years of schooling (39.8%), with a partner (56%), Catholic (73.9%) and belonged to the socioeconomic class C (51.1%). The prevalence of CS was 85.9%, and hot flashes (56.4%) and sweating (50.4%) were the most prevalent symptoms. The most frequent psychological symptoms were nervousness (45%) and emotional liability (44.8%). The severity of vasomotor and psychological symptoms was significantly higher during the peri and postmenopausal period (p&lt;0.05). Vaginal dryness (62.7%) was the most prevalent urogenital complaint.CONCLUSION:The prevalence of CS was high among women from S&#227;o Lu&#237;s, Maranh&#227;o, Brazil.OBJETIVO:Avaliar a prevalência da Síndrome Climatérica (SC) em mulheres de São Luís, Maranhão, uma das regiões menos desenvolvidas do Nordeste brasileiro.MÉTODOS:Estudo descritivo e exploratório de corte transversal, tipo inquérito populacional domiciliar. Foram selecionadas 1.210 mulheres climatéricas de 45 a 60 anos de idade em São Luís, Maranhão, Brasil. As entrevistas foram aplicadas por meio de questionários, no período de abril a julho de 2008, contendo variáveis sociodemográficas, status menopausal e intensidade dos sintomas climatéricos (índices circulatório e psicológico), sendo que para estes últimos foi realizada a sua associação com os períodos pré e pós-menopausal. A técnica de Análise Correspondência Múltipla (ACM) foi utilizada para avaliar a inter-relação entre os sintomas climatéricos.RESULTADOS:A maioria das pacientes tinha entre 55 a 60 anos (35,3%), era de cor parda (37,9%), com 9 a 11 anos de escolaridade (39,8%), com parceiro (56%), católica (73,9%) e de classe social C (51,1%). A prevalência da SC foi de 85,9%, destacando-se fogachos (56,4%) e sudorese (50,4%) como os sintomas vasomotores mais prevalentes. Os sintomas psicológicos mais frequentes foram nervosismo (45%) e irritabilidade (44,8%). Houve predomínio do ressecamento vaginal (62,7%) como a queixa urogenital mais prevalente. A intensidade dos sintomas vasomotores e psicológicos foi significativamente mais elevada nas fases de peri e pós-menopausa (p<0,05).CONCLUSÃO:A prevalência da SC foi elevada em mulheres dessa cidade do Nordeste do Brasil.16316

    First narrow-band search for continuous gravitational waves from known pulsars in advanced detector data

    Spinning neutron stars asymmetric with respect to their rotation axis are potential sources of continuous gravitational waves for ground-based interferometric detectors. In the case of known pulsars a fully coherent search, based on matched filtering, which uses the position and rotational parameters obtained from electromagnetic observations, can be carried out. Matched filtering maximizes the signalto- noise (SNR) ratio, but a large sensitivity loss is expected in case of even a very small mismatch between the assumed and the true signal parameters. For this reason, narrow-band analysis methods have been developed, allowing a fully coherent search for gravitational waves from known pulsars over a fraction of a hertz and several spin-down values. In this paper we describe a narrow-band search of 11 pulsars using data from Advanced LIGO’s first observing run. Although we have found several initial outliers, further studies show no significant evidence for the presence of a gravitational wave signal. Finally, we have placed upper limits on the signal strain amplitude lower than the spin-down limit for 5 of the 11 targets over the bands searched; in the case of J1813-1749 the spin-down limit has been beaten for the first time. For an additional 3 targets, the median upper limit across the search bands is below the spin-down limit. This is the most sensitive narrow-band search for continuous gravitational waves carried out so far

    Search for eccentric black hole coalescences during the third observing run of LIGO and Virgo

    Despite the growing number of confident binary black hole coalescences observed through gravitational waves so far, the astrophysical origin of these binaries remains uncertain. Orbital eccentricity is one of the clearest tracers of binary formation channels. Identifying binary eccentricity, however, remains challenging due to the limited availability of gravitational waveforms that include effects of eccentricity. Here, we present observational results for a waveform-independent search sensitive to eccentric black hole coalescences, covering the third observing run (O3) of the LIGO and Virgo detectors. We identified no new high-significance candidates beyond those that were already identified with searches focusing on quasi-circular binaries. We determine the sensitivity of our search to high-mass (total mass M&gt;70 M⊙) binaries covering eccentricities up to 0.3 at 15 Hz orbital frequency, and use this to compare model predictions to search results. Assuming all detections are indeed quasi-circular, for our fiducial population model, we place an upper limit for the merger rate density of high-mass binaries with eccentricities 0&lt;e≤0.3 at 0.33 Gpc−3 yr−1 at 90\% confidence level

    Search for gravitational-lensing signatures in the full third observing run of the LIGO-Virgo network

    Gravitational lensing by massive objects along the line of sight to the source causes distortions of gravitational wave-signals; such distortions may reveal information about fundamental physics, cosmology and astrophysics. In this work, we have extended the search for lensing signatures to all binary black hole events from the third observing run of the LIGO--Virgo network. We search for repeated signals from strong lensing by 1) performing targeted searches for subthreshold signals, 2) calculating the degree of overlap amongst the intrinsic parameters and sky location of pairs of signals, 3) comparing the similarities of the spectrograms amongst pairs of signals, and 4) performing dual-signal Bayesian analysis that takes into account selection effects and astrophysical knowledge. We also search for distortions to the gravitational waveform caused by 1) frequency-independent phase shifts in strongly lensed images, and 2) frequency-dependent modulation of the amplitude and phase due to point masses. None of these searches yields significant evidence for lensing. Finally, we use the non-detection of gravitational-wave lensing to constrain the lensing rate based on the latest merger-rate estimates and the fraction of dark matter composed of compact objects

    A saúde coletiva tenciona romper com o paradigma tradicional da medicina, centrado no modelo biologicista da saúde-doença. Este estudo visou: avaliar as disciplinas da saúde coletiva oferecidas na graduação dos alunos do curso de Medicina da Universidade Estadual do Ceará (Uece); caracterizar a percepção deles acerca da contribuição dessas disciplinas na relação com o paciente; descrever o conhecimento discente sobre aspectos relacionados à ementa de cada disciplina, como possíveis mudanças na disposição delas; e analisar o conceito de saúde coletiva do ponto de vista dos alunos. Estudo descritivo com abordagem quantitativa, desenvolvido na Uece e nos serviços de saúde conveniados ao curso de Medicina. De uma população de 240 alunos matriculados no curso de Medicina da Uece, retirou-se uma amostra por conveniência de 129 acadêmicos. Os dados foram obtidos mediante questionário semiestruturado. A análise foi realizada com o programa estatístico PASW, versão 17.0. Dos participantes, 112 (86,8%) enfatizaram o efeito positivo das disciplinas na relação com os pacientes. Noventa e um (70,5%) ressaltaram a grande carga horária das disciplinas e 91 (70,5%) desconhecem a ementa. Muitos, 52 (47,7%), sugeriram redução do número de disciplinas e créditos, e 36 (26%) não souberam conceituar saúde coletiva. Conclui-se que esta é essencial na formação dos futuros médicos, mas urge repensar a reformulação curricular e mudanças de atitudes dos docentes desse curso
