The use of body circumferences for the prediction of intra-abdominal fat in obese women with polycystic ovary syndrome

Introduction: Computerizd tomography (CT) is the gold standard for the evaluation of intra- (IAF) and total (TAF) abdominal fat; however, the high cost of the procedure and exposure to radiation limit its routine use. Objective: To develop equations that utilize anthropometric measures for the estimate of IAF and TAF in obese women with polycystic ovary syndrome (PCOS). Methods: The weight, height, BMI, and abdominal (AC), waist (WC), chest (CC), and neck (NC) circumferences of thirty obese women with PCOS were measured, and their IAF and TAF were analyzed by CT. Results: The anthropometric variables AC, CC, and NC were chosen for the TAF linear regression model because they were better correlated with the fat deposited in this region. The model proposed for TAF (predicted) was: 4.63725 + 0.01483 x AC - 0.00117 x NC - 0.00177 x CC (R-2 = 0.78); and the model proposed for IAF was: IAF (predicted) = 1.88541 + 0.01878 x WC + 0.05687 x NC - 0.01529 x CC (R-2 = 0.51). AC was the only independent predictor of TAF (p < 0.01). Conclusion: The equations proposed showed good correlation with the real value measured by CT, and can be used in clinical practice.

Análise de força muscular e composição corporal de mulheres com Síndrome dos Ovários Policísticos

OBJETIVOS: Comparar os parâmetros metabólicos, a composição corporal e a força muscular de mulheres com Síndrome dos Ovários Policísticos (SOP) em relação a mulheres com ciclos menstruais ovulatórios. MÉTODOS: Estudo caso-controle com 27 mulheres com SOP e 28 mulheres controles com ciclos ovulatórios, com idade entre 18 e 37 anos, índice de massa corpórea entre 18 e 39,9 kg/m², que não praticassem atividade física regular. Níveis séricos de testosterona, androstenediona, prolactina, globulina carreadora dos hormônios sexuais (SHBG), insulina e glicemia foram avaliados. Índice de andrógeno livre (FAI) e resistência insulina (por HOMA) foram calculados. As voluntárias submetidas avaliação de composição corporal por dobras cutâneas e absorciometria de raio X de dupla energia (DEXA) e testes de força muscular máxima de 1-RM em três exercícios após procedimento de familiarização e de força isométrica de preensão manual. RESULTADOS: Os níveis de testosterona foram mais elevados no grupo SOP em relação ao CO (68,0±20,2 versus 58,2±12,8 ng/dL; p=0,02), assim como o FAI (282,5±223,8 versus 127,0±77,2; p=0,01), a insulina (8,4±7,0 versus 4,0±2,7 uIU/mL; p=0,01), e o HOMA (2,3±2,3 versus1,0±0,8; p=0,01). O SBHG foi inferior no grupo SOP comparado ao controle (52,5±43,3 versus 65,1±27,4 nmol/L; p=0,04). Não foram observadas diferenças significativas na composição corporal com os métodos propostos entre os grupos. O grupo SOP apresentou maior força muscular no teste de 1-RM nos exercícios supino reto (31,2±4,75 versus 27,8±3,6 kg; p=0,04) e cadeira extensora (27,9±6,2 versus 23,4±4,2 kg; p=0,01), assim como nos testes de força isométrica de preensão manual (5079,6±1035,7 versus 4477,3±69,6 kgf/m²; p=0,04). Ser portadora de SOP foi um preditor independente de aumento de força muscular nos exercícios supino reto (estimativa (E)=2,7) (p=0,04) e cadeira extensora (E=3,5) (p=0,04). Assim como o IMC no exercício de força isométrica de preensão manual do membro dominante (E=72,2) (p<0,01), supino reto (E=0,2) (p=0,02) e rosca direta (E=0,3) (p<0,01). Nenhuma associação foi encontrada entre HOMA-IR e força muscular. CONCLUSÕES: Mulheres com SOP apresentam maior força muscular, sem diferença na composição corporal. A RI não esteve associada ao desempenho da força muscular. Possivelmente, a força muscular pode estar relacionada aos níveis elevados de androgênios nessas mulheres.

Say on Pay: ein Überblick über Gestaltungsoptionen, ökonomische Konsequenzen und Erkenntnisse aus Empirie und Laborexperimenten

Unter dem Stichwort Say on Pay (SoP) haben in den letzen Jahren die meisten Länder der EU und die USA den Aktionären Abstimmungsrechte im Zusammenhang mit der Vergütung des Top-Managements eingeräumt. Zwischen den einzelnen Ländern bestehen jedoch erhebliche Unterschiede hinsichtlich der konkreten Ausgestaltung des SoP. Dieser Beitrag diskutiert die Wirkungen unterschiedlicher Gestaltungsoptionen des SoP auf die Anreizgestaltung und den Nutzen des Managements und der Aktionäre im Rahmen eines einfachen linearen Agency Modells. Dabei erweisen sich das vorvertragliche bindende SoP und das bedingt verpflichtende, nachvertragliche bindende SoP gegenüber den anderen untersuchten Varianten als überlegen. Während das konsultative SoP an seiner mangelnden Durchsetzbarkeit leidet, bietet das nachvertragliche bindende SoP Anreize für opportunistisches Verhalten auf Seiten der Aktionäre und führt deshalb zu Wohlfahrtsverlusten. In Ergänzung der Modellanalyse wird ein Überblick über die wichtigsten empirischen und experimentellen Studien zum Thema SoP gegeben und deren Inhalt im Lichte der Modellergebnisse diskutiert. Most countries of the European Union as well as the US recently introduced shareholder votes on the remuneration of executives, also referred to as “Say on Pay” (SoP). Interestingly, legislators in different jurisdictions opted for quite dissimilar voting right regimes. We provide an overview of the main regulatory approaches and discuss the potential impact of variations in SoP design on the structure of compensation contracts and the utility of shareholders and executives. We find that pre-contractual SoP and conditional post-contractual SoP with binding consequences are in the best interest of shareholders. By contrast, advisory SoP typically suffers from lacking enforceability. We also find that post-contractual SoP with binding consequences results in efficiency losses because it fuels moral hazard on the part of shareholders. We complement the theoretical analysis with a discussion of recent empirical and experimental studies on Say on Pay.

Polarization properties of polymer-based photonic crystal fibers

Selectively filled photonic crystal fibers with polydimethylsiloxane (PDMS), a silicon-type material, have been studied. Is has been demonstrated that polarization properties of these hybrid devices and the properties of the guided light in relation with the temperature changes, finding that the state of polarization (SOP) change with the increasing temperature but remains constant for a wide spectrum of wavelengths for a determinate temperature.

Personalidad e infancia. Diferencias en función de los niveles de perfeccionismo auto-orientado

El objetivo de este trabajo consistió en conocer si existen diferencias en los cinco grandes rasgos de la personalidad (Extraversión, Cordialidad, Neuroticismo, Apertura a la experiencia y Conciencia) entre los participantes con altos y bajos niveles de Perfeccionismo Auto-Orientado (PAO) en población infantil española. Se empleó una muestra compuesta por 483 alumnos entre 8 y 11 años, así como la subescala PAO de la Child and Adolescent Perfectionism Scale (CAPS) y el Cuestionario Big Five de personalidad para niños (BFQ-N) que evalúa los cinco grandes rasgos de la personalidad. Los resultados de la prueba t de Student mostraron que los participantes con altos niveles de PAO obtuvieron medias significativamente más altas en Extraversión, Apertura a la experiencia y Cordialidad que sus iguales con bajos niveles de PAO. Contrariamente, no se observaron diferencias significativas entre ambos grupos en lo que respecta a las puntuaciones medias en Neuroticismo y Conciencia. Los resultados no coinciden con las evidencias empíricas previas, sugiriendo que la relación que se establece entre el PAO y la personalidad puede variar en función de la edad o la cultura.

Polarisation dynamics of vector soliton molecules in mode locked fibre laser

Two fundamental laser physics phenomena - dissipative soliton and polarisation of light are recently merged to the concept of vector dissipative soliton (VDS), viz. train of short pulses with specific state of polarisation (SOP) and shape defined by an interplay between anisotropy, gain/loss, dispersion, and nonlinearity. Emergence of VDSs is both of the fundamental scientific interest and is also a promising technique for control of dynamic SOPs important for numerous applications from nano-optics to high capacity fibre optic communications. Using specially designed and developed fast polarimeter, we present here the first experimental results on SOP evolution of vector soliton molecules with periodic polarisation switching between two and three SOPs and superposition of polarisation switching with SOP precessing. The underlying physics presents an interplay between linear and circular birefringence of a laser cavity along with light induced anisotropy caused by polarisation hole burning.

The UK MPharm (2) - Do we over assess?

Introduction-The pace of structural change in the UK health economies, the new focus on regulation and the breaking down of professional boundaries means that the Royal Pharmaceutical Society of Great Britain (RPSGB) has to continually review the scope, range and outputs of education provided by schools of pharmacy (SOPs). In SOPs, the focus is on equipping students with the knowledge, skills and attitudes necessary to successfully engage with the pre-registration year. The aim of this study [1] was to map current programmes and undergraduate experiences to inform the RPSGB debate. The specific objectives of this paper are to describe elements of the survey of final year undergraduates, to explore student opinions and experiences of their workload, teaching, learning and assessment. Material and methods-The three main research techniques were: (1) quantitative course document review, (2) qualitative staff interview and (3) quantitative student self completion survey. The questions in the survey were based on findings from exploratory focus group work with BPSA (British Pharmaceutical Students’ Association) members and were designed to ascertain if views expressed in the focus groups on the volume and format of assessments were held by the general student cohort. The student self completion questionnaire consisting of 31 questions, was administered in 2005 to all (n=1847) final year undergraduates, using a pragmatic mixture of methods. The sample was 15 SOPs within the UK (1 SOP opted out). The total response rate was 50.62% (n=935): it varied by SOP from 14.42% to 84.62%. The survey data were analysed (n=741) using SPSS, excluding non-UK students who may have undertaken part of their studies within a non-UK university. Results and discussion • 76% (n=562) respondents considered that the amount of formal assessment was about right, 21% (n=158) thought it was too much. • There was agreement that the MPharm seems to have more assessment than other courses, with 63% (n=463) strongly agreeing or agreeing. • The majority considered the balance between examinations and coursework was about right (67%, n=498), with 27% (n=198) agreeing that the balance was too far weighted towards examinations. • 57% (n=421) agreed that the focus of MPharm assessment was too much towards memorised knowledge, 40% (n=290) that it was about right. • 78% (n= 575) agreed with the statement “Assessments don’t measure the skills for being a pharmacist they just measure your knowledge base”. Only 10% (n=77) disagreed. • Similarly 49% (n=358) disagreed with, and 35% (n=256) were not sure about the statement “I consider that the assessments used in the MPharm course adequately measure the skills necessary to be a pharmacist”. Only 17% (n=124) agreed. Experience from this study shows the difficulty of administering survey instruments through UK Schools of Pharmacy. It is heavily dependent on timing, goodwill and finding the right person. The variability of the response rate between SOPs precluded any detailed analysis by School. Nevertheless, there are some interesting results. Issues raised in the exploratory focus group work about amount of assessment and over reliance on knowledge have been confirmed. There is a real debate to be had about the extent to which the undergraduate course, which must instil scientific knowledge, can provide students with the requisite qualities, skills, attitudes and behaviour that are more easily acquired in the pre-registration year.

Random distributed feedback Raman fiber laser with polarized pumping

In this letter, the polarization properties of a random fiber laser operating via Raman gain and random distributed feedback owing to Rayleigh scattering are investigated for the first time. Using polarized pump, the partially polarized generation is obtained with a generation spectrum exhibiting discrete narrow spectral features contrary to the smooth spectrum observed for the depolarized pump. The threshold, output power, degree of polarization and the state of polarization (SOP) of the lasing can be significantly influenced by the SOP of the pump. Fine narrow spectral components are also sensitive to the SOP of the pump wave. Furthermore, we found that random lasing's longitudinal power distributions are different in the case of polarized and depolarized pumping that results in considerable reduction of the generation slope efficiency for the polarized radiation. Our results indicate that polarization effects play an important role on the performance of the random fiber laser. This work improves the understanding of the physics of random lasing in fibers and makes a step forward towards the establishment of the vector model of random fiber lasers.
