Ecotest mamario: una nueva herramienta para la elección del plano de ubicación de los implantes

Antecedentes y Objetivos. Para obtener los mejores resultados en mastoplastia de aumento con implantes, independientemente del volumen y la forma de los mismos, es necesaria la correcta elección del bolsillo de colocación. Para definir el plano apropiado, hasta ahora, nosotros usábamos el clásico test del pellizco (pinch test) siguiendo la corriente bibliográfica mundial. Material y Método. El hecho de que esta medición puede resultar subjetiva y variable debido a las diferentes presiones ejercidas al ser realizado por distintos cirujanos, sumado a que no permite ver lo que realmente estamos pinzando, nos ha llevado a desarrollar la idea de medirlo fiel y objetivamente por medio de un estudio ecográfico preoperatorio al que denominamos ecotest del polo superior. Resultados. Con ésta nueva herramienta diagnóstica hemos evaluado a 95 pacientes, con un seguimiento mínimo de 6 meses de postoperatorio. Conclusiones. De este modo comprobamos la mejoría en nuestros resultados estéticos.

Sauvegarde et valorisation du patrimoine culturel immatériel du Sénègal: projet de création d'un écomusée des pratiques divinatoires et curatives

7 RESUME/ABSTRACT Au Sénégal, il existe des pratiques culturelles et cultuelles, séculaires que l’on retrouve au niveau de toutes les composantes ethnolinguistiques. Une donnée qui nous interpelle, chacun en ce qui nous concerne, et nous invite à repenser le devenir de nos spécificités et particularités culturelles face aux assauts répétés et multiformes de la modernité. La caractéristique qui entoure les rites et rituels est le plus souvent sujette à plusieurs formes d’interprétations fantaisistes et parfois dévalorisantes. Force est de reconnaître que le recours à la médecine moderne ne saurait pleinement répondre à ce besoin de tranquillité et de sérénité mystique qui habite chaque africain en général et chaque sénégalais en particulier. Il s’agit ici, pour l’africain et en ce qui nous concerne le sénégalais, de trouver une tranquillité psychologique et une assurance symbolique propres à créer les conditions d’une guérison physique et/ou morale. En ce sens que l’emprise du modernise ne peut aucunement influer totalement sur cette croyance ancestrale que bon nombre de sénégalais, et pas des moindres, ont en l’endroit de ces pratiques. Une prédisposition culturelle sous-tendue par des préoccupations cultuelles qui font l’objet d’une communion agissante entre les différents membres des communautés. Une prise de conscience qui se manifeste à travers des cérémonies ponctuellement organisées et présidées par des prêtres et prêtresses. Notre présente étude participe de la recherche d’un juste équilibre spirituel et temporel apte à offrir une possibilité de concilier les aspects traditionnels des spécificités culturelles de nos composantes ethnolinguistiques avec ce qui constitue les contraintes et exigences de la modernité. Il reste certes évident que cette opposition a généré une sorte de fracture culturelle en véhiculant une autre manière de voir, mais surtout de percevoir nos traditions et coutumes. Cependant à l’heure d’un redimensionnement et d’une adaptation contextuelle de ce qui constitue nos valeurs identitaires, il nous revient de procéder à une démarche de sensibilisation et d’explication pour conférer plus de lisibilité à nos expressions culturelles. La mise en place d’un écomusée des pratiques divinatoires et curatives, est un moyen moderne et pratique de sauvegarde et de valorisation des savoirs et connaissances thérapeutiques endogènes. Outre la création d’emplois et de revenus, cette infrastructure sera une vitrine du patrimoine local qui favorisera le développement d’un tourisme culturel source de devises et vecteur de développement local; ABSTRACT: In Senegal, there are cultural and religious practices, ancient that we find in all the ethno-linguistic components. A given that challenges us, each in our case, and invites us to rethink the future of our cultural specificities and characteristics and multifaceted face of repeated assaults of modernity. The characteristic surrounding the rites and rituals is usually subject to various forms of demeaning and sometimes fanciful interpretations. We must recognize that the use of modern medicine can not fully meet this need of tranquility and mystical serenity that inhabits every African in general and Senegal in particular each. This is, for Africa and for us Senegalese, find a psychological tranquility and symbolic own insurance to create conditions for physical healing and / or legal. In that the grip of modernizing can in no way affect totally on this ancient belief that many Senegalese, not least, have the place of such practices. A cultural predisposition underpinned by cultic concerns that are the subject of an active communion between the community members. An awareness that manifests itself through occasionally organized ceremonies presided over by priests and priestesses. Our present study involved the search for a fair balance spiritual and temporal able to offer an opportunity to reconcile the traditional aspects of the cultural specificities of our ethno-linguistic components with which constitutes the constraints and demands of modernity. While it remains clear that this opposition has generated a kind of cultural divide by conveying a different way of seeing, but above all to collect our traditions and customs. However at the time resizing and contextual adaptation of what constitutes our identity values, it is our responsibility to conduct an outreach approach and explanation to give greater clarity to our cultural expressions. The establishment of a museum of divination and healing practices, is a modern and convenient way to backup and recovery of therapeutic knowledge and endogenous knowledge. In addition to creating jobs and income, this infrastructure will be a showcase of local heritage that promote the development of cultural tourism source of foreign exchange and local development vector.

Behavioural alterations are independent of sickness behaviour in chronic experimental Chagas disease

The existence of the nervous form of Chagas disease is a matter of discussion since Carlos Chagas described neurological disorders, learning and behavioural alterations in Trypanosoma cruzi-infected individuals. In most patients, the clinical manifestations of the acute phase, including neurological abnormalities, resolve spontaneously without apparent consequence in the chronic phase of infection. However, chronic Chagas disease patients have behavioural changes such as psychomotor alterations, attention and memory deficits, and depression. In the present study, we tested whether or not behavioural alterations are reproducible in experimental models. We show that C57BL/6 mice chronically infected with the Colombian strain of T. cruzi (150 days post-infection) exhibit behavioural changes as (i) depression in the tail suspension and forced swim tests, (ii) anxiety analysed by elevated plus maze and open field test sand and (iii) motor coordination in the rotarod test. These alterations are neither associated with neuromuscular disorders assessed by the grip strength test nor with sickness behaviour analysed by temperature variation sand weight loss. Therefore, chronically T. cruzi-infected mice replicate behavioural alterations (depression and anxiety) detected in Chagas disease patients opening an opportunity to study the interconnection and the physiopathology of these two biological processes in an infectious scenario.

Avaliação de concretos reforçados por confinamento com manta de fibra de vidro estrutural e pré-impreganada

Due to the occurrence of diseases in the use of structural reinforcements in composites, with presentation of concrete blanket detachment, has been identified the need to evaluate the performance of concrete reinforced with glass fiber. This study aims to evaluate these concretes by means of testing methodologies, using concrete with low resistance with structural reinforcement for confinement by preimpregnated glass fiber and traditional fiberglass blanket. The first stage of work was the development of methodologies for analysis, opting for four types, such as the acoustic survey, strength to compressive, the pull-off and ultrasound. Next, tests were carried out using the four selected methodologies in 30 of proof-of-specimens by 5x10 cm, 15 were reinforced with the traditional fiberglass blanket with 5specimens exposed to test a marine environment of marine coastline of Natal-RN and 15 were reinforced with a pre-impregnated glass fiber blanket, as well as 5specimens exposed to a test environment of the marine coastline of Natal-RN. After conducting the acoustic survey, it has been verified a lack of delaminating and air bubbles in the samples, confirming the absence of gross shortcomings in the implementation of the ribs both the traditional fiberglass blanket and in the preimpregnated fiber glass blanket. After carrying out methods of pull-off and compressive strengthening test it was observed that the reinforced proof-bodies with pre-impregnated glass blanket showed maximum stresses higher than the traditional fiberglass blanket; consequently a greater grip with the formation of a smaller area of . fracture, unlike traditional glass mat, which showed lower maximum stresses, with a greater area of fracture. It was also found that the traditional fiberglass blanket presented detachment of blanket-concrete interface, unlike the pre-impregnated fiberglass blanket, which showed a better grip on the blanket-concrete interface. In the trial of ultrasound there was no presence of cracks in the blanket-concrete interface, yielding to both blankets good compactness of the concrete. At the end of this work, they were developed and proposed two methods of testing for evaluation of reinforced concrete structures with composites, for standardization, the acoustic survey and pull-off

One-year follow-up of the nutritional status of patients undergoing liver transplantation

Background: Choosing the method of nutritional assessment is essential for proper follow-up of the nutritional status of patients undergoing liver transplantation. Objectives: Evaluate and compare the nutritional status of cirrhotic patients before and after liver transplantation over a year by different methods of nutritional assessment. Methods: Patients undergoing liver transplantation were assessed in five phases: pre-transplant, 1, 3, 6 and 12 months after transplantation at the hospital Santa Casa de Misericordia de Porto Alegre, RS, Brazil. The methods used for nutritional assessment were anthropometry, grip strength of the non-dominant hand (HGS) by dynamometry, thickness of the adductor pollicis muscle (APM) and phase angle (PA) by bioelectrical impedance analysis (BIA). In all evaluations, the same measurements were taken. Results: Evaluations were performed in 22 patients. Methods that showed a higher prevalence of malnourished patients before transplantation were PA by BIA (25%), arm muscle circumference (AMC) (21.9%) and arm circumference (AC) (18.8%). When comparing the nutritional status of patients during follow-up, there was a significant difference only in the evaluation methods AC, triceps skinfold thickness and PA by BIA. At the end, the methods of nutritional assessment were compared again. They showed a significant statistical difference, with HGS being the best method for detecting malnutrition. Conclusions: In conclusion, it is suggested that the method PA by BIA could be widely used with this population since the results are consistent with other findings in the literature and they are significant, reliable, and reproducible.

Desenvolvimento de argamassa para restauração utilizando resíduo do polimento do porcelanato

The coatings mortars are essential elements of building structures because they execute an important role in protecting walls and are particularly exposed to aggressive action responsible for its degradation over time. The importance of wall coverings has been the subject of discussion and analysis in the conservation and rehabilitation of old buildings. Are sometimes removed and replaced with inappropriate solutions of constructive point of view or architecture. The most commonly used coatings on walls of old buildings is based on traditional hydraulic lime mortars. The present study aims at the formulation of new lime- based mortars and aerial fine aggregate, in order to contribute to a better field of conservation and restoration mortar coating of old buildings. Residue was used for polishing porcelain as fine aggregate, replacing the aggregate (sand), in percentages 05-30% by mass. We conducted a thorough evaluation of the mortar properties in fresh and hardened state by comparing the performance of the same with a reference mortar. The residue used was characterized as the density, bulk density, and particle size laser, scanning electron microscopy, X-ray diffraction and X-ray fluorescence. Formulations were produced 7, 6 with residue and one commonly used formulation, which served as a reference. In the formulations of lime mortars air (hydrated lime powder CH-I) has been adopted a stroke volume (1:3) with constant binder, was varied and the water / binder and aggregate and waste. For evaluation of mortars fresh, proceeded to consistency analysis, specific gravity, water retention and air content embedded. In the hardened state assays were performed in specific gravity, water retention, modulus of elasticity, tensile strength in bending, compressive strength, water absorption by capillary action, adhesion, tensile strength, resistance to shrinkage and salts by of crystallization trials with resources chloride solution, nitrate and sulfate all sodium in prismatic at 90 days of age, in addition to the micro structural analysis of mortars. Based on the results we can see that the mortar formulated with 10% content of waste and the reference free retraction feature more stable closer to neutrality. The composition of 10% was obtained better performance against the action of the salt crystallization. The mortar with 15% residue obtained better density, lower air content embedded and high capacity for water retention developing good workability. The replacement of 20% of waste generates a satisfactory utilization of resistance to compression, flexion and traction grip the base. And, finally, it can be seen that the mortar with 10, 15 and 20% residual show, in principle, good suitability as coatings, thus enabling a final result consistent with durability, workability and aesthetics developing therefore a material with better performance to repair or replace existing mortars in old buildings

La famille nucléaire au 21e siècle : quelle place pour le père?

Depuis les débuts de la deuxième vague féministe, la participation quasi-universelle des femmes au marché du travail a causé la perte, pour les pères de famille, du rôle de pourvoyeur exclusif que ces derniers avaient tenu depuis si longtemps. Les femmes hétérosexuelles de la société contemporaine sont dorénavant plus scolarisées et atteignent des carrières plus avancées que leurs contreparties masculines. Alors que les femmes soutiennent davantage la famille par leurs emplois, les hommes doivent proportionnellement assumer des rôles plus actifs et participatifs à la maison. En cette période de transition, de transformation et de redéfinition rapides des rôles genrés à l’intérieur de l’économie familiale hétérosexuelle, les pères participent de manière plus équitable à l’éducation des enfants et à l’entretien du domicile, ces rôles ayant longtemps été attribués presque exclusivement aux femmes. Ces nouvelles responsabilités détonnent avec les représentations stéréotypées des hommes dans la culture populaire, ainsi qu’avec les modèles d’identification de la masculinité normative que les hommes ont requis et requièrent toujours sous l’égide de l’hétérosexualité imposée. De ce fait, les hommes occidentaux de moins de cinquante ans se trouvent souvent à cheval entre deux mondes d’exigences concurrentes. La place que peuvent et doivent prendre les pères au sein de leurs familles requiert un questionnement critique. L’ironie de la place du père peut être comprise comme la tension entre les normes du genre rétrogrades ou conservatrices et les exigences – à la fois politiques et pragmatiques – de la masculinité de la classe moyenne contemporaine. Cette tension fondamentale et structurante de la masculinité contemporaine est vécue par l’anxiété d’association au genre, ainsi qu’à travers des difficultés filiales, paternelles et intergénérationnelles. Ce mémoire de maîtrise adopte une approche déconstructiviste envers l’analyse de constructions contemporaines de la masculinité reproductive. À travers les gender studies, la théorie queer ainsi que la psychanalyse, le mémoire offre des lectures analytiques du discours de croissance personnelle de John Stoltenberg, de la fiction autobiographique de Karl Ove Knausgaard, ainsi que de la série télévisée américaine Dexter.

Experience modulates the psychophysiological response of airborne warfighters during a tactical combat parachute jump

We aimed to analyse the effect of experience level in the psychophysiological response and specific fine motor skills of novel and expert parachute warfighters during a tactical combat parachute jump. We analysed blood oxygen saturation, heart rate, salivary cortisol, blood glucose, lactate and creatinkinase, leg strength, isometric hand-grip strength, cortical arousal, specific fine motor skills and cognitive anxiety, somatic anxiety and self-confident before and after a tactical combat parachute jump in 40 warfighters divided in two group, novel (n = 17) and expert group (n = 23). Novels presented a higher heart rate, lactate, cognitive anxiety, somatic anxiety and a lower self-confident than experts during the jump. We concluded that experience level has a direct effect on the psychophysiological response since novel paratroopers presented a higher psychophysiological response than compared to the expert ones, however this result neither affected the specific fine motor skills nor the muscle structure after a tactical combat parachute jump.

Valores de referencia de la fuerza prensil en escolares colombianos. Estudio FUPRECOL

The primary aim of this study was to generate normative handgrip strength (HG) data for 10- to 17.9-year-olds. The secondary aim was to determine the relative proportion of Colombian children and adolescents that fall into established Health Benefit Zones (HBZ). This cross-sectional study is enrolling 7268 schoolchildren (boys n=3129 and girls n=4139, age 12.7 (2.4) years old. HG was measured using a hand dynamometer with an adjustable grip. Five HBZs (Needs Improvement, Fair, Good, Very Good, and Excellent) have been established that correspond to combined-HG. Centile smoothed curves, percentile and tables for the 3rd, 10th, 25th, 50th, 75th, 90th and 97th percentile were calculated using Cole’s LMS method. HG peaked in the sample at 22.2 (8.9) kg in boys and 18.5 (5.5) kg in girls. The increase in HG was greater for boys than for girls, but the peak HG was lower in girls than in boys. The HBZ data indicated that a higher overall percentage of boys than girls at each age group fell into the “Needs Improvement” zone, with differences particularly pronounced during adolescence. Our results provide, for the first time, sex- and age-specific HG reference standards for Colombian schoolchildren aged 9-17.9 years.

Handgrip strength cut-off for cardiometabolic risk index among Colombian children and adolescents : the FUPRECOL study

Abstract Objective: Evidence shows an association between muscular strength (MS) and health among youth, however low muscular strength cut-points for the detection of high metabolic risk in Latin-American populations are scarce. The aim of this study was two-fold: to explore potential age- and sex-specific thresholds of MS, for optimal cardiometabolic risk categorization among Colombian children and adolescents; and to investigate if cardiometabolic risk differed by MS group by applying the receiver operating characteristic curve (ROC) cut point. Methods: This is a secondary analysis of a cross-sectional study (the FUPRECOL study), published elsewhere. The FUPRECOL study assessments were conducted during the 2014– 2015 school year. MS was estimated by a handle dynamometer on 1,950 children and adolescents from Colombia, using the MS relative to weight (handgrip strength/body mass). A metabolic risk score was computed from the following components: waist circumference, triglycerides, HDL-c, glucose, systolic and diastolic blood pressure. ROC analysis showed a significant discriminatory accuracy of MS in identifying the low/high metabolic risk in children and adolescents and both gender. Results: In children, handgrip strength/body mass level for a low metabolic risk were 0.359 and 0.376 in girls and boys, respectively. In adolescents, these points were 0.440 and 0.447 in girls and boys, respectively. Conclusion: In conclusion, the results suggest a hypothetical MS level relative to weight for having a low metabolic risk, which could be used to identify youths at risk.
