Fish oil intakes providing dietary attainable levels of EPA and DHA reduces blood pressure in adults with systolic hypertension in a retrospective analysis

Background: Although a large number of randomized controlled trials (RCTs) have examined the impact of the n-3 (ω-3) fatty acids EPA (20:5n-3) and DHA (22:6n-3) on blood pressure and vascular function, the majority have used doses of EPA+DHA of > 3 g per d,which are unlikely to be achieved by diet manipulation. Objective: The objective was to examine, using a retrospective analysis from a multi-center RCT, the impact of recommended, dietary achievable EPA+DHA intakes on systolic and diastolic blood pressure and microvascular function in UK adults. Design: Healthy men and women (n = 312) completed a double-blind, placebo-controlled RCT consuming control oil, or fish oil providing 0.7 g or 1.8 g EPA+DHA per d in random order each for 8 wk. Fasting blood pressure and microvascular function (using Laser Doppler Iontophoresis) were assessed and plasma collected for the quantification of markers of vascular function. Participants were retrospectively genotyped for the eNOS rs1799983 variant. Results: No impact of n-3 fatty acid treatment or any treatment * eNOS genotype interactions were evident in the group as a whole for any of the clinical or biochemical outcomes. Assessment of response according to hypertension status at baseline indicated a significant (P=0.046) fish oil-induced reduction (mean 5 mmHg) in systolic blood pressure specifically in those with isolated systolic hypertension (n=31). No dose response was observed. Conclusions: These findings indicate that, in those with isolated systolic hypertension, daily doses of EPA+DHA as low as 0.7 g bring about clinically meaningful blood pressure reductions which, at a population level, would be associated with lower cardiovascular disease risk. Confirmation of findings in an RCT where participants are prospectively recruited on the basis of blood pressure status is required to draw definite conclusions.

Acute benefits of the microbial-derived isoflavone metabolite equol on arterial stiffness in men prospectively recruited according to equol producer phenotype: a double-blind randomized controlled trial

There is much speculation with regard to the potential cardioprotective benefits of equol, a microbial-derived metabolite of the isoflavone daidzein, which is produced in the large intestine after soy intake in 30% of Western populations. Although cross-sectional and retrospective data support favorable associations between the equol producer (EP) phenotype and cardiometabolic health, few studies have prospectively recruited EPs to confirm this association. The aim was to determine whether the acute vascular benefits of isoflavones differ according to EP phenotype and subsequently investigate the effect of providing commercially produced S-(–)equol to non-EPs. We prospectively recruited male EPs and non-EPs (n = 14/ group) at moderate cardiovascular risk into a double-blind, placebocontrolled crossover study to examine the acute effects of soy isoflavones (80-mg aglycone equivalents) on arterial stiffness [carotid-femoral pulse-wave velocity (cfPWV)], blood pressure, endothelial function (measured by using the EndoPAT 2000; Itamar Medical), and nitric oxide at baseline (0 h) and 6 and 24 h after intake. In a separate assessment, non-EPs consumed 40 mg S-(–)equol with identical vascular measurements performed 2 h after intake. After soy intake, cfPWV significantly improved in EPs at 24 h (cfPWV change from 0 h: isoflavone, 20.2 6 0.2 m/s; placebo, 0.6 6 0.2 m/s; P , 0.01), which was significantly associated with plasma equol concentrations (R = 20.36, P = 0.01). No vascular effects were observed in EPs at 6 h or in non-EPs at any time point. Similarly, no benefit of commercially produced S-(–)equol was observed in non-EPs despite mean plasma equol concentrations reaching 3.2 mmol/L. Acute soy intake improved cfPWV in EPs, equating to an 11–12% reduced risk of cardiovascular disease if sustained. However, a single dose of commercially produced equol had no cardiovascular benefits in non-EPs. These data suggest that the EP phenotype is critical in unlocking the vascular benefits of equol in men, and long-term trials should focus on confirming the implications of EP phenotype on cardiovascular health. This trial was registered at clinicaltrials.gov as NCT01530893. Am J Clin Nutr doi: 10.3945/ajcn.115.125690.

Impact of lipoprotein lipase gene polymorphism, S447X, on postprandial triacylglycerol and glucose response to sequential meal ingestion

Lipoprotein lipase (LPL) is a key rate-limiting enzyme for the hydrolysis of triacylglycerol (TAG) in chylomicrons and very low-density lipoprotein. Given that postprandial assessment of lipoprotein metabolism may provide a more physiological perspective of disturbances in lipoprotein homeostasis compared to assessment in the fasting state, we have investigated the influence of two commonly studied LPL polymorphisms (rs320, HindIII; rs328, S447X) on postprandial lipaemia, in 261 participants using a standard sequential meal challenge. S447 homozygotes had lower fasting HDL-C (p = 0.015) and a trend for higher fasting TAG (p = 0.057) concentrations relative to the 447X allele carriers. In the postprandial state, there was an association of the S447X polymorphism with postprandial TAG and glucose, where S447 homozygotes had 12% higher TAG area under the curve (AUC) (p = 0.037), 8.4% higher glucose-AUC (p = 0.006) and 22% higher glucose-incremental area under the curve (IAUC) (p = 0.042). A significant gene–gender interaction was observed for fasting TAG (p = 0.004), TAG-AUC (Pinteraction = 0.004) and TAG-IAUC (Pinteraction = 0.016), where associations were only evident in men. In conclusion, our study provides novel findings of an effect of LPL S447X polymorphism on the postprandial glucose and gender-specific impact of the polymorphism on fasting and postprandial TAG concentrations in response to sequential meal challenge in healthy participants

Urinary metabolomic profiling to identify biomarkers of a flavonoid-rich and flavonoid-poor fruits and vegetables diet: the FLAVURS trial in adults: the FLAVURS trial

The present study aims to investigate the dose dependent effects of consuming diets enriched in flavonoid-rich and flavonoid-poor fruits and vegetables on the urine metabolome of adults who had a C1.5 fold increased risk of cardiovascular diseases. A single-blind, dose-dependent, parallel randomized controlled dietary intervention was conducted where volunteers (n = 126) were randomly assigned to one of three diets: high flavonoid diet, low flavonoid diet or habitual diet as a control for 18 weeks. High resolution LC– MS untargeted metabolomics with minimal sample cleanup was performed using an Orbitrap mass spectrometer. Putative biomarkers which characterize diets with high and low flavonoid content were selected by state-of-the-art data analysis strategies and identified by HR-MS and HR-MS/MS assays. Discrimination between diets was observed by application of two linear mixedmodels: one including a diet-time interaction effect and the second containing only a time effect. Valerolactones, phenolic acids and their derivatives were among sixteen biomarkers related to the high flavonoid dietary exposure. Four biomarkers related to the low flavonoid diet belonged to the family of phenolic acids. For the first time abscisic acid glucuronide was reported as a biomarker after a dietary intake, however its origins have to be examined by future hypothesis driven experiments using a more targeted approach. This metabolomic analysis has identified a number of dose dependent urinary biomarkers (i.e. proline betaine or iberin-N-acetyl cysteine), which can be used in future observation and intervention studies to assess flavonoids and nonflavonoid phenolic intakes and compliance to fruit and vegetable intervention.

A New Yardstick for Rating Dental Arch Relationship in Patients With Complete Bilateral Cleft Lip and Palate

Objective: To develop yardsticks for assessment of dental arch relationship in young individuals with repaired complete bilateral cleft lip and palate appropriate to different stages of dental development. Participants: Eleven cleft team orthodontists from five countries worked on the projects for 4 days. A total of 776 sets of standardized plaster models from 411 patients with operated complete bilateral cleft lip and palate were available for the exercise. Statistics: The interexaminer reliability was calculated using weighted kappa statistics. Results: The interrater weighted kappa scores were between .74 and .92, which is in the ""good"" to ""very good"" categories. Conclusions: Three bilateral cleft lip and palate yardsticks for different developmental stages of the dentition were made: one for the deciduous dentition (6-year-olds` yardstick), one for early mixed dentition (9-year-olds` yardstick), and one for early permanent dentition (12-year-olds` yardstick).

A Longitudinal Three-Center Study of Dental Arch Relationship in Patients With Bilateral Cleft Lip and Palate

Objective: To compare and evaluate longitudinally the dental arch relationships from 4.5 to 13.5 years of age with the Bauru-BCLP Yardstick in a large sample of patients with bilateral cleft lip and palate (BCLP). Design: Retrospective longitudinal intercenter outcome study. Patients: Dental casts of 204 consecutive patients with complete BCLP were evaluated at 6, 9, and 12 years of age. All models were identified only by random identification numbers. Setting: Three cleft palate centers with different treatment protocols. Main Outcome Measures: Dental arch relationships were categorized with the Bauru-BCLP yardstick. Increments for each interval (from 6 to 9 years, 6 to 12 years, and 9 to 12 years) were analyzed by logistic and linear regression models. Results: There were no significant differences in outcome measures between the centers at age 12 or at age 9. At age 6, center B showed significantly better results (p = .027), but this difference diminished as the yardstick score for this group increased over time (linear regression analysis), the difference with the reference category (center C, boys) for the intervals 6 to 12 and 9 to 12 years being 10.4% (p = .041) and 12.9% (p = .009), respectively. Conclusions: Despite different treatment protocols, dental arch relationships in the three centers were comparable in final scores at age 9 and 12 years. Delaying hard palate closure and employing infant orthopedics did not appear to be advantageous in the long run. Premaxillary osteotomy employed in center B appeared to be associated with less favorable development of the dental arch relationship between 9 and 12 years.

Vårdpersonalens upplevelse av personcentrerat förhållningssätt i vården av personer med demenssjukdom : en fenomenologisk studie

Studiens syfte har varit att beskriva vårdpersonalens upplevelse av hur de utifrån ett personcentrerat förhållningssätt i vården arbetar med personer med demenssjukdom. Intervjuer har genomförts med fem deltagare som alla har erfarenhet från vård av personer med demens och dessa intervjuer analyserades sedan med en fenomenologisk analysmetod enligt Amedeo Giorgi. Utgångspunkten för studien har varit den personcentrerade formuleringen som definieras i de Nationella riktlinjerna för vård och omsorg vid demenssjukdom. Resultatet visar att deltagarna sätter fokus på individanpassade behov som har en tidskrävande inlärningsperiod. För att bevara patientens personlighet behövs kunskap om personen, dennes aktiviteter är viktigt att de får fortsätta med och att misslyckanden i situationen att försöka förstå personen med demens skall ses som nyckeln till framgång. För samspelet med den demenssjuke försöker personalen undvika konflikter och tilliten till varandra är av stor betydelse. Medbestämmandet innebär ofta att personalen påverkar personen i positiv riktning och att den öppna dialogen med dennes anhöriga är betydande.Sammanfattningsvis så visar resultatet i denna studie att deltagarna har en god personcentrerad omvårdnadssyn i sitt arbete även om de till viss del har för mycket fokus på fysiska behov hos patienten. Det krävs dock personer med speciella kompetenser för att klara detta samtidigt som verksamheten måste tillgodose en liten skara personer runt personen med demens.

Factors associated with evidence-based practice among registered nurses in Sweden : a national cross-sectional study

Background: Evidence-based practice (EBP) is emphasized to increase the quality of care and patient safety. EBP is often described as a process consisting of distinct activities including, formulating questions, searching for information, compiling the appraised information, implementing evidence, and evaluating the resulting practice. To increase registered nurses' (RNs') practice of EBP, variables associated with such activities need to be explored. The aim of the study was to examine individual and organizational factors associated with EBP activities among RNs 2 years post graduation. Methods: A cross-sectional design based on a national sample of RNs was used. Data were collected in 2007 from a cohort of RNs, included in the Swedish Longitudinal Analyses of Nursing Education/Employment study. The sample consisted of 1256 RNs (response rate 76%). Of these 987 RNs worked in healthcare at the time of the data collection. Data was self-reported and collected through annual postal surveys. EBP activities were measured using six single items along with instruments measuring individual and work-related variables. Data were analyzed using logistic regression models. Results: Associated factors were identified for all six EBP activities. Capability beliefs regarding EBP was a significant factor for all six activities (OR = 2.6 - 7.3). Working in the care of older people was associated with a high extent of practicing four activities (OR = 1.7 - 2.2). Supportive leadership and high collective efficacy were associated with practicing three activities (OR = 1.4 - 2.0). Conclusions: To be successful in enhancing EBP among newly graduated RNs, strategies need to incorporate both individually and organizationally directed factors.

La thématique de l’eau dans l’œuvre de Marguerite Duras

The aim of this thematic study is to examine how the water motif is used in Marguerite Duras’s literary work. The study shows that water has multiple functions in these texts: it is linked to major themes and creates an enigmatic atmosphere by its association with the unknown, the inexplicable and the unconscious. The strong presence of water in Duras’s texts is striking. References to the water element can be found in several titles throughout her career, from early works such as Un barrage contre le Pacifique (1950) to La mer écrite (1996), published just after her death. Almost all of her fiction take place near water – and the rain or the sound of waves serve as leitmotifs in specific novels. The water motif can play a metonymic as well as a metaphoric role in the texts and it sometimes takes on human or animalistic characteristics (Chapter 4). Several emblematic Durassian characters (e.g. the beggar-woman, Anne-Marie Stretter and Lol V. Stein) have a close relationship to water (Chapter 5). The water motif is linked to many major Durassian themes, and illustrates themes with positive connotations, for example, creation, fecundity, maternity, liberty and desire, as well as themes with negative connotations such as destruction and death (Chapter 6). A close reading of three novels, La vie tranquille (1944), L’après-midi de Monsieur Andesmas (1962) and La maladie de la mort (1982), shows that the realism of the first novel is replaced by intriguing evocations of the sea and the pond in the second text, motifs which resist straightforward interpretation. The enigmatic feeling persists in the last novel, in which the sea illustrates the overall sombre mood of the story (Chapter 7). Finally, the role of the water element in psychoanalytic theory is discussed (Chapter 8), and a parallel is drawn between the Jungian concept of the mother archetype and the water motif in Duras’s texts. The suggestion is made in this last chapter that water is used to illustrate an oriental influence (Taoist or Buddhist) of some of the female characters in Duras’s work.

As relações de trabalho nas organizações de economia solidária : um paralelo Brasil-França

O objetivo desta pesquisa é o estudo das relações que se estabelecem entre o trabalhador e seu trabalho em organizações não convencionais, isto é, que não se identificam com o modo capitalista de produção e que reivindicam, pelo contrário, a criatividade e a originalidade de um trabalho mais autônomo, mais justo e mais responsável: a economia solidária. O que significa, para o trabalhador, atuar nestas organizações? É a pergunta que orienta este estudo. Dito de outro modo: a experiência vivida no trabalho cotidiano pelo trabalhador da economia solidária manifesta-se mediante práticas profissionais e práticas sociais reveladoras de novas formas de inserção no trabalho e na sociedade? Seria essa experiência fruto de uma transformação que ocorre em alguns segmentos do mundo do trabalho e observável em outros contextos econômicos ou um reflexo da situação particularmente fragilizada dos trabalhadores brasileiros? Tratar-se-á então de entender a singularidade da participação dos trabalhadores a este projeto, seu impacto sobre o desenvolvimento de seu trabalho e das relações estabelecidas com a organização e de estudar as transformações que podem ocorrer nas relações sociais a partir do trabalho. Este será analisado sob uma dimensão subjetiva, como experiência de construção identitária, e sob uma dimensão institucional, como socialização para e pela solidariedade. O conceito de “trabalho solidário”, que reúne essas dimensões, será analisado apoiando-se, em grande parte, na obra de François Dubet e sua teoria do ator, da estrutura social e da socialização. A pesquisa se inscreve numa perspectiva de contribuição à Sociologia do Trabalho e das relações de trabalho sem a pretensão de realizar uma sociologia da economia solidária, nas suas múltiplas relações com a sociedade. O que está em foco é a transformação das relações entre o trabalhador e seu trabalho. O argumento defendido pela pesquisa é que as relações que nascem de uma experiência cotidiana do trabalho nas organizações da economia solidária são peculiares e diversificadas, mas interpelam e desafiam o conjunto das relações sociais. Portanto, o trabalho realizado nessas organizações talvez seria, apesar de suas ambigüidades, suscetível de estimular novas formas de relações sociais por meio de uma socialização assentada na solidariedade. Três tipos de organizações “referências” (tipos ideais) são construídos a partir do tipo de produção dominante e dos valores e objetivos que motivam a ação: organizações de produção, associações culturais e organizações humanitárias. A comparação Brasil – França, através das organizações investigadas em Porto Alegre e Paris, procura homologias, isto é: correspondências na construção da ação apesar de contextos diferentes, assim como a reconstrução de processos e procura de especificidades que possam enriquecer as interações. No decorrer da investigação, o que se encontrou, tanto no Brasil quanto na França, foi de um lado, um discurso “oficial” (mentores, militantes da economia solidária e pesquisadores) que descreve a tarefa que se atribui a economia solidária: a responsabilização de todos para transformar a sociedade. Por outro lado, encontrou-se, através do discurso dos trabalhadores, o relato da realidade quotidiana que aparece como um mundo de tensões e contradições. Para entender essa aparente incompatibilidade, foi preciso recriar os mecanismos de construção do trabalho solidário: em que medida pode-se falar de experiência social e em que medida a socialização para e pela solidariedade é bem sucedida. Para tanto, foi necessário recompor o processo de construção das relações sociais dentro e fora do trabalho, manifestado mediante estratégias dos atores que precisam se posicionar frente às lógicas de ação desenvolvidas pelas organizações. A seguir, analisou-se a possibilidade de encontrar semelhanças e diferenças entre o Brasil e a França na construção deste trabalho solidário. Enfim, procurou-se responder à pergunta que originou esta pesquisa: seria mesmo o trabalho solidário gerador de novas relações sociais no trabalho e no âmbito mais amplo da sociedade?

Revisitando a obra de Celestin Freinet: limites e possibilidades de uma proposta de educação popular na escola pública

Esta dissertação analisa a obra que Célestin Freinet, professor primário público desenvolveu na Fiança entre 1920 e 1966. Esta obra só se torna compreensível em profundidade, se recolocada no contexto sócio-econômico,político e educacional em que foi gerada: a formação do capitalismo francês, com suas peculiaridades e o tipo de sociedade que engendrou; o regime republicano nascido da Revolução de 1789, que atinge seu auge no final do século XIX e início do século XX, com o advento da Terceira República; a escola pública, pedra angular deste regime e palco da batalha pela definitiva instauração do republicanismo no país e, finalmente, o corpo docente, principal, ator desta batalha.

Caminhos para a universalização dos serviços de água e esgotos no Brasil: a atuação das entidades reguladoras para indução da eficiência dos prestadores de serviços

The deficit of water and sewerage services is a historic problem in Brazil. The introduction of a new regulatory framework, in 2007, presented ways intending to overcome these deficits, among them, the providers efficiency improvement. This thesis aims to analyze the regulators performance regarding its ability to induce the efficiency of the Brazilian water and sewerage services providers. To this end, an analytical approach based on a sequential explanatory strategy was used, and it consists of three steps. In the first step, the Data Envelopment Analysis ( DEA ) was used to measure the providers efficiency in 2006 and 2011. The results show that the average efficiency may be considered high; however significant inefficiencies among the 29 analyzed providers were detected. The ones in the Southeast region showed better performance level and Northeast had the lowest. The local and the private providers were more efficient on average. In 2006 and 2011 the average performance was higher among non-regulated providers. In 2006 the group regulated by local agencies had the best average performance, in 2011, the best performance was the group regulated by the consortium agencies. To analyse the second step was used the Malmquist Index, it pointed that the productivity between 2006 and 2011 dropped. The analysis through decomposing Malmquist Index showed a shift of technical efficiency frontier to a lower level, however was detected a small provider s advance towards the frontier. Only the Midwest region recorded progress in overall productivity. The deterioration in the total factor productivity was higher among regional providers but the local ones and the private agencies moved quickly to the frontier level. The providers regulated from 2007 showed less decrease on the total productivity and the results of the catch up effect were more meaningful. In the last step, the regulators standardization activity analyses noted that there are agencies that had not issued rules until 2011. The most standards topics discussed in the issued rules were the tariff adjustments and the setting of general conditions for the provision and use of services; in another hand, the least covered topics were new technologies incentive and the introduction of efficiency-inducing regulatory mechanisms and productivity gains for price reviews. Regulators created from 2007 were more active proportionately. Even with the advent of the regulatory framework and the creation of new regulatory bodies, the evidence points to a reality in which the actions of these agencies have not been ensuring that providers of water and sewage, regulated by them, has achieved better performance. The non- achievement of regulatory goals can be explained by the incipient level of performance of the Brazilian regulatory authorities, which should be strengthened because of its potential contribution to the Brazilian basic sanitation department

Proxy-reported health-related quality of life of patients with juvenile idiopathic arthritis: Pediatric rheumatology international trials organization multinational quality of life cohort study

Objective. To investigate the proxy-reported health-related quality of life (HRQOL) and its determinants in patients with juvenile idiopathic arthritis (JIA).Methods. In this multinational, multicenter, cross-sectional study, HRQOL of patients with JIA was assessed through the Child Health Questionnaire (CHQ) and was compared with that of healthy children of similar age from the same geographic area. of joint inflammation, Childhood Health Assessment Questionnaire (CHAQ), and erythrocyte sedimentation rate.Results. A total of 6,639 participants (3,324 with JIA and 3,315 healthy) were enrolled from 32 countries. The mean SD physical and psychosocial summary scores of the CHQ were significantly lower in patients with JIA than in healthy children (physical: 44.5 +/- 10.6 versus 54.6 +/- 4.0, P < 0.0001; psychosocial: 47.6 +/- 8.7 versus 51.9 +/- 7.59 P < 0.0001), with the physical well-being domain being most impaired. Patients with persistent oligoarthritis had better HRQOL compared with other subtypes, whereas HRQOL was similar across patients with systemic arthritis, polyarthritis, and extended oligoarthritis. A CHAQ score > 1 and a pain intensity rating > 3.4 cm on a 10-cm visual analog scale were the strongest determinants of poorer HRQOL in the physical and psychosocial domains, respectively.Conclusion. We found that patients with JIA have a significant impairment of their HRQOL compared with healthy peers, particularly in the physical domain. Physical well-being was mostly affected by the level of functional impairment, whereas the intensity of pain had the greatest influence on psychosocial health.

Preliminary core sets of measures for disease activity and damage assessment in juvenile systemic lupus erythematosus and juvenile dermatomyositis

Objective. To identify preliminary core sets of outcome variables for disease activity and damage assessment in juvenile systemic lupus erythematosus (JSLE) and juvenile dermatomyositis (JDM). Methods. Two questionnaire surveys were mailed to 267 physicians from 46 different countries asking each member to select and rank the response variables used when assessing clinical response in patients with JSLE or JDM. Next, 40 paediatric rheumatologists from 34 countries met and, using the nominal group technique, selected the domains to be included in the disease activity and damage core sets for JSLE and JDM. Results. A total of 41 response variables for JSLE and 37 response variables for JDM were selected and ranked through the questionnaire surveys. In the consensus conference, domains selected for both JSLE and JDM activity or damage core sets included the physician and parent/patient subjective assessments and a global score tool. Domains specific for JSLE activity were the immunological tests and the kidney function parameters. Concerning JDM, functional ability and muscle strength assessments were indicated for both activity and damage core sets, whereas serum muscle enzymes were included only in the activity core set. A specific paediatric domain called 'growth and development' was introduced in the disease damage core set for both diseases and the evaluation of health-related quality of life was advised in order to capture the influence of the disease on the patient lifestyle. Conclusions. We developed preliminary core sets of measures for disease activity and damage assessment in JSLE and JDM. The prospective validation of the core sets is in progress.
