Physicochemical characteristic of Exudate of Dacryodes edulis

The Present work deals with the study of exudate of Dacryodes edulis with regards to various seasonal physicochemical properties of the purified solids exudate, acid hydrolysis product and saponification product like charring temperature (oC) (195.73 ± 4.75, 190 ± 7.9, 190 ± 3.4, ); flash point (oC) (105 ± 5.0, 100 ± 7.9, 100 ± 3.4); moisture content % (1.32 – 1.35, 1.05 – 1.08, 1.00 - 1.10); ash content (%) (1.77 – 1.85, 1.21 – 1.31, 1.26 -1.37); lignin content (%) (7.77 – 7.85, 6.21 – 6.31, 5.26 – 5.37); electrical conductivity (μS/cm) (28.40 -29.20, 32.10 – 33.00, 30.30 – 30.90); density (g/cm3) (0.76 -0.77, 0.94 – 0.98, 0.88 – 0.98); melting point (oC) (61.08 – 73.35, 58.69 – 73.35, 55.35 – 65.67). The physicochemical characteristic of Dacryodes edulis is found to be fluctuated with seasonal variations during the present investigation. The correlation coefficient showed positive relationship among the properties. The study reveals that exudate of Daryodes edulis can be tapped in large quantity in the dry season and is rich in lignin content but the seasons does not affect the properties.

Factors associated with obesity in Brazilian children enrolled in the School Health Program: a case-control study

Case-control studies evaluating the factors associated with childhood obesity are scarce in Brazil. We aimed to analyze the factors associated with obesity in Brazilian schoolchildren enrolled in the School Health Program.A case-control study was conducted on 80 schoolchildren aged 7 to 9 years, 40 of them obese and 40 of normal weight according to the cut-off points established by the World Health Organization (2007). Weight, height and waist circumference were obtained. Socioeconomic, demographic, health, eating behavior and lifestyle data were collected by applying a questionnaire to the person responsible and by determining his/her nutritional status. A binary unconditional logistic regression model (univariate and multivariate) was used for data analysis. The prevalence of obesity was 7.21%. The final model showed that duration of breast-feeding ≥6 months of age (OR 5.3; 95% CI: 1.3-22.1), excess weight of the person responsible (OR 7.1; 95% CI: 1.2-40.2), a sedentary level of physical activity (OR 4.1; 95% CI: 1.115.5), and fast chewing (OR 7.4; 95% CI: 2.1-26.9) were significantly associated with childhood obesity. The factors associated with obesity in schoolchildren were duration of breast-feeding ≥6 months, persons responsible with excess weight, and sedentary children who chew fast. The present study contributes information to be used for the health actions planned by the School Health Program.

Eficacia del uso de vancomicina tópica en cirugía cardíaca en la prevención de complicaciones esternales

La complicación esternal engloba tanto la infección esternal superficial como la infección esternal profunda. La mediastinitis, o infección esternal profunda, a pesar de su baja incidencia (0,5 al 3,6%), continúa siendo una importante complicación de la esternotomía media en cirugía cardíaca, debido a su alta morbilidad y mortalidad (variable del 10 al 47%) y coste sanitario. La incidencia de infección esternal superficial varía según las series del 2,1% al 6,4%. Tiene una mortalidad menor (0,5-2,1%), aunque también alarga la estancia hospitalaria y el coste sanitario. En las últimas décadas se han empleado antibióticos locales como vancomicina o gentamicina para prevenir la aparición de complicación esternal. Diversos estudios han demostrado que con la aplicación tópica de antibióticos se alcanza mayor concentración local en hueso que con la administración de antibióticos sistémicos solos. Pacientes y Métodos Se trata de un estudio de casos y controles retrospectivo con 1263 pacientes intervenidos de cirugía cardíaca mediante esternotomía media de forma consecutiva desde el 01/01/2011 hasta el 31/12/2014 en el Hospital Virgen de la Victoria. Estos pacientes son divididos en dos grupos en función de la administración tópica de vancomicina en los bordes esternales tras la realización de la esternotomía: el grupo en el que se ha administrado la vancomicina tópica (grupo Vancomicina), con 659 pacientes, y el grupo de control, con 604 pacientes. El criterio de administración de vancomicina tópica no fue aleatorio, sino según la decisión del cirujano. . Resultados La incidencia de infección esternal superficial fue de 1,26%, similar en ambos grupos (1,36% en el grupo Vancomicina y 1,2% en el grupo Control). La incidencia de infección esternal profunda o mediastinitis fue de 1,58%, y resultó significativamente diferente en ambos grupos: 0,9% en el grupo Vancomicina y 2,3% en el grupo Control (p 0,045). Las variables que resultaron factores de riesgo independientes para el desarrollo de mediastinitis fueron la obesidad, la intubación prolongada, la reoperación por sangrado y la cirugía sobre la aorta torácica ascendente. Para la infección esternal superficial fueron la obesidad, el uso de mamaria bilateral, el tabaquismo y la cirugía sobre la aorta torácica. La vancomicina resultó un factor protector para mediastinitis en el análisis multivariante (p 0,041, OR 0,338). La incidencia de mortalidad en la complicación esternal fue del 8,33%. Los factores de riesgo relacionados con mortalidad en el análisis univariante fueron la intubación orotraqueal prolongada, la infección por gérmenes Gram negativos y la estancia en UCI y hospitalaria prolongadas, ninguna significativa en el análisis multivariante. En nuestra serie predominaron las infecciones por Gram negativos, en contra de lo publicado recientemente. En el grupo Vancomicina disminuyó la incidencia de infecciones por gérmenes Gram positivos. Conclusiones La incidencia de complicaciones esternales infecciosas en nuestro hospital es baja y comparable con la publicada en la literatura. La incidencia de infección esternal profunda es significativamente menor en el grupo Vancomicina, resultando el uso de vancomicina en el análisis multivariante un factor protector que reduce la aparición de infección esternal profunda casi en un 70% de los casos.

Interaction and cooperative effort among scientific societies. Twelve years of COSCE

The evolution of knowledge and technology in recent decades has brought profound changes in science policy, not only in the countries but also in the supranational organizations. It has been necessary, therefore, to adapt the scientific institutions to new models in order to achieve a greater and better communication between them and the political counterparts responsible for defining the general framework of relations between science and society. The Federationon of Scientific Societies of Spain (COSCE, Confederación de Sociedades Científicas de España) was founded in October 2003 to respond to the urgent need to interact with the political institutions and foster a better orientation in the process of making decisions about the science policy. Currently COSCE consists of over 70 Spanish scientific societies and more than 40,000 scientists. During its twelve years of active life, COSCE has developed an intense work of awareness of the real situation of science in Spain by launching several initiatives (some of which have joined other organizations) or by joining initiatives proposed from other groups related to science both at the Spanish level and at the European and non-European scenarios.

A kingdom near lost: English military recovery in Ireland, 1600-03

Ireland was rarely a peaceful realm for Elizabeth I, but Hugh O’Neill, Earl of Tyrone and his allies brought the edifice of English power in Ireland to the brink of collapse. The war in Ireland at the end of the sixteenth century devoured money, lives and reputations at a prodigious rate. However seven years of Irish success ended when in 1600 the Queen appointed Charles Blount, Lord Mountjoy as Lord Deputy. Success replaced failure, but only after the new Lord Deputy transformed English strategy and rebuilt the army into an instrument fit for purpose.

The role of area-level deprivation and gender in participation in population-based faecal immunochemical test (FIT) colorectal cancer screening

This study aimed to investigate the effects of sex and deprivation on participation in a population-based faecal immunochemical test (FIT) colorectal cancer screening programme. The study population included 9785 individuals invited to participate in two rounds of a population-based biennial FIT-based screening programme, in a relatively deprived area of Dublin, Ireland. Explanatory variables included in the analysis were sex, deprivation category of area of residence and age (at end of screening). The primary outcome variable modelled was participation status in both rounds combined (with “participation” defined as having taken part in either or both rounds of screening). Poisson regression with a log link and robust error variance was used to estimate relative risks (RR) for participation. As a sensitivity analysis, data were stratified by screening round. In both the univariable and multivariable models deprivation was strongly associated with participation. Increasing affluence was associated with higher participation; participation was 26% higher in people resident in the most affluent compared to the most deprived areas (multivariable RR = 1.26: 95% CI 1.21–1.30). Participation was significantly lower in males (multivariable RR = 0.96: 95%CI 0.95–0.97) and generally increased with increasing age (trend per age group, multivariable RR = 1.02: 95%CI, 1.01–1.02). No significant interactions between the explanatory variables were found. The effects of deprivation and sex were similar by screening round. Deprivation and male gender are independently associated with lower uptake of population-based FIT colorectal cancer screening, even in a relatively deprived setting. Development of evidence-based interventions to increase uptake in these disadvantaged groups is urgently required.

Excessive blood pressure increase with exercise and risk of all-cause mortality and cardiac events

The association of an excessive blood pressure increase with exercise (EBPIE) on cardiovascular outcomes remains controversial. We sought to assess its impact on the risk of all-cause mortality and major cardiac events in patients with known or suspected coronary artery disease (CAD) referred for stress testing. Exercise echocardiography was performed in 10,047 patients with known or suspected CAD. An EBPIE was defined as an increase in systolic blood pressure with exercise ≥80 mmHg. The endpoints were all-cause mortality and major cardiac events (MACE), including cardiac death or nonfatal myocardial infarction (MI). Overall, 573 patients exhibited an EBPIE during the tests. Over a mean follow-up of 4.8 years, there were 1,950 deaths (including 725 cardiac deaths), 1,477 MI, and 1,900 MACE. The cumulative 10-year rates of all-cause mortality, cardiac death, nonfatal MI and MACE were 32.9%, 13.1%, 26,9% and 33% in patients who did not develop an EBPIE vs. 18.9%, 4.7%, 17.5% and 20.7% in those experiencing an EBPIE, respectively (p <0.001 for all comparisons). In Cox regression analyses, an EBPIE remained predictive of all-cause mortality (hazard ratio [HR] 0.73, 95% confidence interval [CI] 0.59-0.91, p = 0.004), cardiac death (HR 0.67, 95% CI 0.46-0.98, p = 0.04), MI (HR 0.67, 95% CI 0.52-0.86, p = 0.002), and MACE (HR 0.69, 95% CI 0.56-0.86, p = 0.001). An EBPIE was associated with a significantly lower risk of mortality and MACE in patients with known or suspected CAD referred for stress testing.

Urinary osteopontin predicts incident chronic kidney disease, while plasma osteopontin predicts cardiovascular death in elderly men

Background and objectives The matricellular protein osteopontin is involved in the pathogenesis of both kidney and cardiovascular disease. However, whether circulating and urinary osteopontin levels are associated with the risk of these diseases is less studied. Design, setting, participants and measurements A community-based cohort of elderly (Uppsala Longitudinal Study of Adult Men [ULSAM; n=741; mean age: 77 years]) was used to study the associations between plasma and urinary osteopontin, incident chronic kidney disease, and the risk of cardiovascular death during a median of 8 years of follow-up. Results There was no significant cross-sectional correlation between plasma and urinary osteopontin (Spearman rho=0.07, p=0.13). Higher urinary, but not plasma osteopontin, was associated with incident chronic kidney disease in multivariable models adjusted for age, cardiovascular risk factors, baseline glomerular filtration rate (GFR), urinary albumin/creatinine ratio, and inflammatory markers interleukin 6 and high sensitivity C-reactive protein (Odds ratio for 1-standard deviation (SD) of urinary osteopontin, 1.42, 95% CI (1.00-2.02), p=0.048). Conversely, plasma osteopontin, but not urinary osteopontin, was independently associated with cardiovascular death (multivariable hazard ratio per SD increase, 1.35, 95% CI (1.14-1.58), p<0.001, and 1.00, 95% CI (0.79-1.26), p=0.99, respectively). The addition of plasma osteopontin to a model with established cardiovascular risk factors significantly increased the C-statistics for the prediction of cardiovascular death (p<0.002). Conclusions Higher urinary osteopontin specifically predicts incident chronic kidney disease while plasma osteopontin specifically predicts cardiovascular death. Our data put forward osteopontin as an important factor in the detrimental interplay between the kidney and the cardiovascular system. The clinical implications, and why plasma and urinary osteopontin mirror different pathologies, remains to be established.

Alcances y límites del principio de la responsabilidad de proteger: actuación del consejo de seguridad frente al conflicto en libia en el 2011 y Siria durante el periodo 2011-2014.

El propósito de este estudio de caso es determinar los alcances y límites de la Responsabilidad de Proteger, tomando como ejemplo la actuación del Consejo de Seguridad de Naciones Unidas ante el conflicto en Libia y Siria. Para esto es necesario analizar fuentes primarias documentos oficiales y secundarias como artículos académicos, para así comprobar que la evolución del concepto de soberanía ha permitido que se legitimen las intervenciones con fines humanitarios, ya que todos los Estados tienen la responsabilidad de garantizar la protección de los derechos humanos de sus ciudadanos, de lo contrario, la comunidad internacional debe tomar medidas para evitar o detener los crímenes masivos.
