Charged Dilatonic AdS Black Branes in Arbitrary Dimensions

We study electromagnetically charged dilatonic black brane solutions in arbitrary dimensions with flat transverse spaces, that are asymptotically AdS. This class of solutions includes spacetimes which possess a bulk region where the metric is approximately invariant under Lifshitz scalings. Given fixed asymptotic boundary conditions, we analyze how the behavior of the bulk up to the horizon varies with the charges and derive the extremality conditions for these spacetimes.Comment: References update

Precision Measurement of the Newtonian Gravitational Constant Using Cold Atoms

About 300 experiments have tried to determine the value of the Newtonian gravitational constant, G, so far, but large discrepancies in the results have made it impossible to know its value precisely. The weakness of the gravitational interaction and the impossibility of shielding the effects of gravity make it very difficult to measure G while keeping systematic effects under control. Most previous experiments performed were based on the torsion pendulum or torsion balance scheme as in the experiment by Cavendish in 1798, and in all cases macroscopic masses were used. Here we report the precise determination of G using laser-cooled atoms and quantum interferometry. We obtain the value G=6.67191(99) x 10^(-11) m^3 kg^(-1) s^(-2) with a relative uncertainty of 150 parts per million (the combined standard uncertainty is given in parentheses). Our value differs by 1.5 combined standard deviations from the current recommended value of the Committee on Data for Science and Technology. A conceptually different experiment such as ours helps to identify the systematic errors that have proved elusive in previous experiments, thus improving the confidence in the value of G. There is no definitive relationship between G and the other fundamental constants, and there is no theoretical prediction for its value, against which to test experimental results. Improving the precision with which we know G has not only a pure metrological interest, but is also important because of the key role that G has in theories of gravitation, cosmology, particle physics and astrophysics and in geophysical models.Comment: 3 figures, 1 tabl

Performance of the CMS Cathode Strip Chambers with Cosmic Rays

The Cathode Strip Chambers (CSCs) constitute the primary muon tracking device in the CMS endcaps. Their performance has been evaluated using data taken during a cosmic ray run in fall 2008. Measured noise levels are low, with the number of noisy channels well below 1%. Coordinate resolution was measured for all types of chambers, and fall in the range 47 microns to 243 microns. The efficiencies for local charged track triggers, for hit and for segments reconstruction were measured, and are above 99%. The timing resolution per layer is approximately 5 ns

Relationship between functional fitness, medication costs and mood in elderly people

Objective: to verify if functional fitness (FF) is associated with the annual cost of medication consumption and mood states (MSt) in elderly people. Methods: a cross-sectional study with 229 elderly people aged 65 years or more at Santa Casa de Misericórdia de Coimbra, Portugal. Seniors with physical and psychological limitations were excluded, as well as those using medication that limits performance on the tests. The Senior Fitness Test was used to evaluate FF, and the Profile of Mood States - Short Form to evaluate the MSt. The statistical analysis was based on Mancova, with adjustment for age, for comparison between men and women, and adjustment for sex, for comparison between cardiorespiratory fitness quintiles. The association between the variables under study was made with partial correlation, controlling for the effects of age, sex and body mass index. Results: an inverse correlation between cardiorespiratory fitness and the annual cost of medication consumption was found (p < 0.01). FF is also inversely associated with MSt (p < 0.05). Comparisons between cardiorespiratory fitness quintiles showed higher medication consumption costs in seniors with lower aerobic endurance, as well as higher deterioration in MSt (p < 0.01). Conclusion: elderly people with better FF and, specifically, better cardiorespiratory fitness present lower medication consumption costs and a more positive MSt

The association between disrespect and abuse of women during childbirth and postpartum depression: Findings from the 2015 Pelotas birth cohort study

Background: This study examined the association between disrespect and abuse of women during facility-based childbirth and postpartum depression (PD) occurrence. Methods: We used data from the 2015 Pelotas (Brazil) Birth Cohort, a population-based cohort of all live births in the city. We assessed 3065 mothers at pregnancy and 3-months after birth. Self-reported disrespect and abuse experiences included physical abuse, verbal abuse, denial of care, and undesired procedures. We estimate the occurrence of each disrespect and abuse type, one or more types and disrespect and abuse score. The Edinburgh Postnatal Depression Scale (EPDS) was used to assess PD. EPDS scores ≥13 and ≥15 indicated at least moderate PD and marked/severe. Odds ratios (OR) were calculated by logistic regression. Results: The prevalence of at least moderate PD and marked/severe PD was 9.4% and 5.7%, respectively. 18% of the women experienced at least one type of disrespect and abuse. Verbal abuse increased the odds of having at least moderate PD (OR = 1.58; 95%CI 1.06–2.33) and marked/severe PD (OR = 1.69; 95%CI 1.06–2.70) and the effect among women who did not experience antenatal depressive symptoms was greater in comparison to those who did (OR = 2.51; 95%CI 1.26–5.04 and OR = 4.27; 95%CI 1.80–10.12). Physical abuse increased the odds of having marked/severe PD (OR = 2.28; 95%CI 1.26–4.12). Having experienced three or more mistreatment types increased the odds of at least moderate PD (OR = 2.90; 95%CI 1.30 - 35.74) and marked/severe PD (OR=3.86; 95%CI 1.58–9.42). Limitations: Disrespect and abuse experiences during childbirth were self-reported. Conclusions: Disrespect and abuse during childbirth increased the odds of PD three months after birth. Strategies to promote high quality and respectful maternal health care are needed to prevent mother-child adverse outcomes

Percepção, conhecimento e uso de medicamentos genéricos no Sul do Brasil: o que mudou entre 2002 e 2012?

Resumo: Este estudo compara a percepção, conhecimento e uso de medicamentos genéricos em adultos de Pelotas, Rio Grande do Sul, Brasil, por meio de dois estudos transversais de base populacional realizados em 2002 e 2012. Os desfechos estudados foram: (a) prevalência de utilização de medicamentos genéricos; (b) proporção de uso de medicamentos genéricos entre os demais medicamentos; (c) percepção dos usuários sobre preço e qualidade dos medicamentos genéricos; (d) conhecimento dos usuários sobre medicamentos genéricos; e (e) estratégias de aquisição de medicamentos. A prevalência de uso de medicamentos genéricos aumentou de 3,6% (IC95%: 3,0-4,3) para 26,1% (IC95%: 24,5-27,7) no período de dez anos. A percepção sobre preço e qualidade dos medicamentos genéricos se manteve estável, a identificação das características que diferenciam os medicamentos genéricos dos demais medicamentos melhorou (p < 0,001) e o erro de classificação de medicamento diminuiu (p < 0,001). Houve um aumento significativo na estratégia de aquisição de medicamentos pela substituição do medicamento prescrito pelo medicamento genérico. Entre 2002 e 2012, aumentou o conhecimento e uso de medicamentos genéricos, enquanto a percepção quanto ao menor preço e qualidade equivalente mantiveram-se elevadas

Desigualdade no acesso a medicamentos para doenças crônicas em mulheres brasileiras

O objetivo deste trabalho foi analisar a prevalência de acesso a medicamentos para tratamento de doenças crônicas e a existência de desigualdades socioeconômicas no acesso. Os dados são da Pesquisa Nacional de Demografia e Saúde e da Mulher e da Criança de 2006, com uma amostra de 15.575 mulheres (15 a 49 anos). Dessas, 7.717 tiveram diagnóstico de doença crônica com necessidade de obtenção de medicamento e foram consideradas elegíveis para o estudo. O desfecho foi construído com base no diagnóstico de doença crônica e na necessidade de obtenção de medicamento para o tratamento. A análise ajustada foi conduzida usando-se a regressão de Poisson. Os grupos que apresentaram maior prevalência de acesso foram os domiciliados na zona rural, com uma ou duas doenças crônicas e com nível socioeconômico mais elevado. A prevalência de acesso encontrada foi alta, no entanto, as análises demonstram que existe desigualdade socioeconômica no acesso a medicamentos a favor dos mais ricos, identificando como grupo mais vulnerável aquele dos indivíduos mais pobres e com maior número de doenças crônicas

Physical activity and medicine use: evidence from a population-based study

BACKGROUND: Few studies have investigated the association between physical activity practice and medicine use; data from these studies are inconsistent. The aim of this study was to evaluate the association between level of physical activity and medicine use in adults aged 20 years or more. METHODS: A population-based cross-sectional study was carried out in the first semester of 2002 in the urban area of Pelotas; a medium-sized Southern Brazilian city. Physical activity was assessed with the short version of the International Physical Activity Questionnaire. A physical activity score was created as the weekly time spent in moderate-intensity activities plus twice the weekly time spent in vigorous-intensity activities. Medicine use in the 15 days prior to the interview was also assessed. Adjusted analyses taking into account the sampling design was carried out using Poisson regression. Wald tests for heterogeneity and linear trend were used to calculate significance. RESULTS: Out of the 3,182 individuals interviewed, 41% were not sufficiently active according to current physical activity guidelines. Only 34% of the subjects did not use medicines in the previous 15 days, and 18% used three or more drugs in the same period. Level of physical activity was inversely associated with the number of medicines used both in the crude and in the adjusted analyses. CONCLUSION: There are well-documented benefits of physical activity for several chronic diseases in the literature. Data from the present study suggest that medicine use is also positively affected by physical activity behavior
