Barriers and facilitators to public bicycle scheme use : a qualitative approach

The purpose of this study was to explore barriers and facilitators to using CityCycle, a public bicycle share scheme in Brisbane, Australia. Focus groups were conducted with participants belonging to one of three categories. Group one consisted of infrequent and noncyclists (no bicycle riding over the past month), group two were regular bicycle riders (ridden a bicycle at least once in the past month) and group three was composed of CityCycle members. A thematic analytic method was used to analyse the data. Three main themes were found: Accessibility/spontaneity, safety and weather/topography. The lengthy sign-up process was thought to stifle the spontaneity typically thought to attract people to public bike share. Mandatory helmet legislation was thought to reduce spontaneous use. Safety was a major concern for all groups and this included a perceived lack of suitable bicycle infrastructure, as well as regular riders describing a negative attitude of some car drivers. Interestingly, CityCycle riders unanimously perceived car driver attitudes to improve when on CityCycle bicycles relative to riding on personal bicycles. Conclusions: In order to increase the popularity of the CityCycle scheme, the results of this study suggest that a more accessible, spontaneous sign-up process is required, 24/7 opening hours, and greater incentives to sign up new members and casual users, as seeing people using CityCycle appears critical to further take up.

Reality bites: When copyright law and reality cooking meet, only the lawyers win

There’s nothing new about this recipe for success: toss in high-stress scenarios, flavour generously with competitive chefs, and garnish with a panel of celebrity judges. With all major broadcasters in the country now dishing up some form of reality cooking programme, Australians could be forgiven for having lost any expectation of original TV material. But that didn’t stop Channel Seven from taking Channel Nine to court last week, arguing its copyright in My Kitchen Rules had been infringed with Nine’s latest prime-time effort, The Hotplate. After the first few episodes went to air, Seven asked for an injunction to stop Nine from broadcasting any more episodes of the reality show. So let’s look at some common confusions about copyright law and how it relates to reality television. Because in this context, copyright infringement isn’t about shows sharing major similarities, or about protecting ideas, but rather the expression of these ideas in the final product. Still, stretching copyright law to protect the “vibe” of a work isn’t good for artists, TV producers or viewers: copyright was designed to nurture creativity, not stifle it.

Greenwashing the Trans-Pacific Partnership: Fossil fuels, the environment, and climate change

There has been much controversy over the Trans-Pacific Partnership (TPP) – a plurilateral trade agreement involving a dozen nations from throughout the Pacific Rim – and its impact upon the environment, biodiversity, and climate change. The secretive treaty negotiations involve Australia and New Zealand; countries from South East Asia such as Brunei Darussalam, Malaysia, Singapore, Vietnam, and Japan; the South American nations of Peru and Chile; and the members of the 1994 North American Free Trade Agreement (NAFTA), Canada, Mexico and the United States. There was an agreement reached between the parties in October 2015. The participants asserted: ‘We expect this historic agreement to promote economic growth, support higher-paying jobs; enhance innovation, productivity and competitiveness; raise living standards; reduce poverty in our countries; and to promote transparency, good governance, and strong labor and environmental protections.’ The final texts of the agreement were published in November 2015. There has been discussion as to whether other countries – such as Indonesia, the Philippines, and South Korea – will join the deal. There has been much debate about the impact of this proposed treaty upon intellectual property, the environment, biodiversity and climate change. There have been similar concerns about the Trans-Atlantic Trade and Investment Partnership (TTIP) – a proposed trade agreement between the United States and the European Union. In 2011, the United States Trade Representative developed a Green Paper on trade, conservation, and the environment in the context of the TPP. In its rhetoric, the United States Trade Representative has maintained that it has been pushing for strong, enforceable environmental standards in the TPP. In a key statement in 2014, the United States Trade Representative Mike Froman insisted: ‘The United States’ position on the environment in the Trans-Pacific Partnership negotiations is this: environmental stewardship is a core American value, and we will insist on a robust, fully enforceable environment chapter in the TPP or we will not come to agreement.’ The United States Trade Representative maintained: ‘Our proposals in the TPP are centered around the enforcement of environmental laws, including those implementing multilateral environmental agreements (MEAs) in TPP partner countries, and also around trailblazing, first-ever conservation proposals that will raise standards across the region’. Moreover, the United States Trade Representative asserted: ‘Furthermore, our proposals would enhance international cooperation and create new opportunities for public participation in environmental governance and enforcement.’ The United States Trade Representative has provided this public outline of the Environment Chapter of the TPP: A meaningful outcome on environment will ensure that the agreement appropriately addresses important trade and environment challenges and enhances the mutual supportiveness of trade and environment. The Trans-Pacific Partnership countries share the view that the environment text should include effective provisions on trade-related issues that would help to reinforce environmental protection and are discussing an effective institutional arrangement to oversee implementation and a specific cooperation framework for addressing capacity building needs. They also are discussing proposals on new issues, such as marine fisheries and other conservation issues, biodiversity, invasive alien species, climate change, and environmental goods and services. Mark Linscott, an assistant Trade Representative testified: ‘An environment chapter in the TPP should strengthen country commitments to enforce their environmental laws and regulations, including in areas related to ocean and fisheries governance, through the effective enforcement obligation subject to dispute settlement.’ Inside US Trade has commented: ‘While not initially expected to be among the most difficult areas, the environment chapter has emerged as a formidable challenge, partly due to disagreement over the United States proposal to make environmental obligations binding under the TPP dispute settlement mechanism’. Joshua Meltzer from the Brookings Institute contended that the trade agreement could be a boon for the protection of the environment in the Pacific Rim: Whether it is depleting fisheries, declining biodiversity or reduced space in the atmosphere for Greenhouse Gas emissions, the underlying issue is resource scarcity. And in a world where an additional 3 billion people are expected to enter the middle class over the next 15 years, countries need to find new and creative ways to cooperate in order to satisfy the legitimate needs of their population for growth and opportunity while using resources in a manner that is sustainable for current and future generations. The TPP parties already represent a diverse range of developed and developing countries. Should the TPP become a free trade agreement of the Asia-Pacific region, it will include the main developed and developing countries and will be a strong basis for building a global consensus on these trade and environmental issues. The TPP has been promoted by its proponents as a boon to the environment. The United States Trade Representative has maintained that the TPP will protect the environment: ‘The United States’ position on the environment in the TPP negotiations is this: environmental stewardship is a core American value, and we will insist on a robust, fully enforceable environment chapter in the TPP or we will not come to agreement.’ The United States Trade Representative discussed ‘Trade for a Greener World’ on World Environment Day. Andrew Robb, at the time the Australian Trade and Investment Minister, vowed that the TPP will contain safeguards for the protection of the environment. In November 2015, after the release of the TPP text, Rohan Patel, the Special Assistant to the President and Deputy Director of Intergovernmental Affairs, sought to defend the environmental credentials of the TPP. He contended that the deal had been supported by the Nature Conservancy, the International Fund for Animal Welfare, the Joint Ocean Commission Initiative, the World Wildlife Fund, and World Animal Protection. The United States Congress, though, has been conflicted by the United States Trade Representative’s arguments about the TPP and the environment. In 2012, members of the United States Congress - including Senator Ron Wyden (D-OR), Olympia Snowe (R-ME), and John Kerry (D-MA) – wrote a letter, arguing that the trade agreement needs to provide strong protection for the environment: ‘We believe that a '21st century agreement' must have an environment chapter that guarantees ongoing sustainable trade and creates jobs, and this is what American businesses and consumers want and expect also.’ The group stressed that ‘A binding and enforceable TPP environment chapter that stands up for American interests is critical to our support of the TPP’. The Congressional leaders maintained: ‘We believe the 2007 bipartisan congressional consensus on environmental provisions included in recent trade agreements should serve as the framework for the environment chapter of the TPP.’ In 2013, senior members of the Democratic leadership expressed their opposition to granting President Barack Obama a fast-track authority in respect of the TPP House of Representatives Minority Leader Nancy Pelosi said: ‘No on fast-track – Camp-Baucus – out of the question.’ Senator Majority leader Harry Reid commented: ‘I’m against Fast-Track: Everyone would be well-advised to push this right now.’ Senator Elizabeth Warren has been particularly critical of the process and the substance of the negotiations in the TPP: From what I hear, Wall Street, pharmaceuticals, telecom, big polluters and outsourcers are all salivating at the chance to rig the deal in the upcoming trade talks. So the question is, Why are the trade talks secret? You’ll love this answer. Boy, the things you learn on Capitol Hill. I actually have had supporters of the deal say to me ‘They have to be secret, because if the American people knew what was actually in them, they would be opposed. Think about that. Real people, people whose jobs are at stake, small-business owners who don’t want to compete with overseas companies that dump their waste in rivers and hire workers for a dollar a day—those people, people without an army of lobbyists—they would be opposed. I believe if people across this country would be opposed to a particular trade agreement, then maybe that trade agreement should not happen. The Finance Committee in the United States Congress deliberated over the Trans-Pacific Partnership negotiations in 2014. The new chair Ron Wyden has argued that there needs to be greater transparency in trade. Nonetheless, he has mooted the possibility of a ‘smart-track’ to reconcile the competing demands of the Obama Administration, and United States Congress. Wyden insisted: ‘The new breed of trade challenges spawned over the last generation must be addressed in imaginative new policies and locked into enforceable, ambitious, job-generating trade agreements.’ He emphasized that such agreements ‘must reflect the need for a free and open Internet, strong labor rights and environmental protections.’ Elder Democrat Sander Levin warned that the TPP failed to provide proper protection for the environment: The TPP parties are considering a different structure to protect the environment than the one adopted in the May 10 Agreement, which directly incorporated seven multilateral environmental agreements into the text of past trade agreements. While the form is less important than the substance, the TPP must provide an overall level of environmental protection that upholds and builds upon the May 10 standard, including fully enforceable obligations. But many of our trading partners are actively seeking to weaken the text to the point of falling short of that standard, including on key issues like conservation. Nonetheless, 2015, President Barack Obama was able to secure the overall support of the United States Congress for his ‘fast-track’ authority. This was made possible by the Republicans and dissident Democrats. Notably, Oregon Senator Ron Wyden switched sides, and was transformed from a critic of the TPP to an apologist for the TPP. For their part, green political parties and civil society organisations have been concerned about the secretive nature of the negotiations; and the substantive implications of the treaty for the environment. Environmental groups and climate advocates have been sceptical of the environmental claims made by the White House for the TPP. The Green Party of Aotearoa New Zealand, the Australian Greens and the Green Party of Canada have released a joint declaration on the TPP observing: ‘More than just another trade agreement, the TPP provisions could hinder access to safe, affordable medicines, weaken local content rules for media, stifle high-tech innovation, and even restrict the ability of future governments to legislate for the good of public health and the environment’. In the United States, civil society groups such as the Sierra Club, Public Citizen, WWF, the Friends of the Earth, the Rainforest Action Network and 350.org have raised concerns about the TPP and the environment. Allison Chin, President of the Sierra Club, complained about the lack of transparency, due process, and public participation in the TPP talks: ‘This is a stealth affront to the principles of our democracy.’ Maude Barlow’s The Council of Canadians has also been concerned about the TPP and environmental justice. New Zealand Sustainability Council executive director Simon Terry said the agreement showed ‘minimal real gains for nature’. A number of organisations have joined a grand coalition of civil society organisations, which are opposed to the grant of a fast-track. On the 15th January 2013, WikiLeaks released the draft Environment Chapter of the TPP - along with a report by the Chairs of the Environmental Working Group. Julian Assange, WikiLeaks' publisher, stated: ‘Today's WikiLeaks release shows that the public sweetener in the TPP is just media sugar water.’ He observed: ‘The fabled TPP environmental chapter turns out to be a toothless public relations exercise with no enforcement mechanism.’ This article provides a critical examination of the draft Environment Chapter of the TPP. The overall argument of the article is that the Environment Chapter of the TPP is an exercise in greenwashing – it is a public relations exercise by the United States Trade Representative, rather than a substantive regime for the protection of the environment in the Pacific Rim. Greenwashing has long been a problem in commerce, in which companies making misleading and deceptive claims about the environment. In his 2012 book, Greenwash: Big Brands and Carbon Scams, Guy Pearse considers the rise of green marketing and greenwashing. Government greenwashing is also a significant issue. In his book Storms of My Grandchildren, the climate scientist James Hansen raises his concerns about government greenwashing. Such a problem is apparent with the TPP – in which there was a gap between the assertions of the United States Government, and the reality of the agreement. This article contends that the TPP fails to meet the expectations created by President Barack Obama, the White House, and the United States Trade Representative about the environmental value of the agreement. First, this piece considers the relationship of the TPP to multilateral environmental treaties. Second, it explores whether the provisions in respect of the environment are enforceable. Third, this article examines the treatment of trade and biodiversity in the TPP. Fourth, this study considers the question of marine capture fisheries. Fifth, there is an evaluation of the cursory text in the TPP on conservation. Sixth, the article considers trade in environmental services under the TPP. Seventh, this article highlights the tensions between the TPP and substantive international climate action. It is submitted that the TPP undermines effective and meaningful government action and regulation in respect of climate change. The conclusion also highlights that a number of other chapters of the TPP will impact upon the protection of the environment – including the Investment Chapter, the Intellectual Property Chapter, the Technical Barriers to Trade Chapter, and the text on public procurement.

Inclusão de estudantes com deficiência na universidade Estadual do Oeste do Paraná UNIOESTE

O presente trabalho tem como objetivo analisar as políticas de inclusão e as condições de permanência dos alunos com deficiência na Universidade Estadual do Oeste do Paraná (UNIOESTE). Para tanto, contextualizaram-se as circunstâncias históricas do processo de inclusão/exclusão, reconhecendo as possíveis limitações enfrentadas nos sistemas de ensino superior brasileiro, e abordaram-se as linhas e diretrizes da educação do Estado do Paraná. Utilizaram-se entrevistas semiestruturadas para abordar alunos com deficiência (física, sensorial e/ou cognitiva), professores, coordenadores de cursos, diretores de Câmpus e de Centros onde esses alunos encontravam-se matriculados, integrantes do Programa Institucional de Ações Relativas às Pessoas com Necessidades Especiais (PEE) e gestores dos cinco Câmpus da Universidade. As declarações apresentadas pelos entrevistados reconhecem a relevância do PEE, destacando serem imprescindíveis as ações desenvolvidas pela equipe nas bancas do processo seletivo vestibular, porém apontaram para a necessidade de medidas para uma real efetivação do Programa, o que implica maiores repasses de subsídios financeiros e a realização de concursos públicos para a contratação de profissionais especializados para atender a demanda existente em todos os Câmpus da instituição. Foi possível identificar que a UNIOESTE não atende os requisitos das normas brasileiras do setor da construção civil (NBR 9050/2004) e a inexistência de políticas de permanência na Instituição impõe limites para a diversidade existente. Correlacionadas a essas questões, identificou-se barreiras que comprometem a inclusão na UNIOESTE, abrangendo as barreiras atitudinais, físicas e sistêmicas. Conclui-se que o debate sobre a inclusão das pessoas com deficiência precisa se enraizar na estrutura interna da universidade e na concepção política e elitista do governo do Estado do Paraná, que ainda possui fortes ondas conservadoras, que muitas vezes sufocam os movimentos contra-hegemônicos, dificultando esse processo de inclusão de todos numa universidade pública, gratuita e de qualidade

On being a good nurse: reflections on the past and preparing for the future

On being a good nurse: reflections on the past and preparing for the future. The objectives of this paper include reflecting on the attributes of the ‘good’ nurse in the past, outlining thematically the essential attributes (virtues) required by the ‘good’ nurse today and presenting an original four- point framework for ethics in practice. While there is no doubt that nurses in the past were highly professional, the culture within which they practiced tended to stifle the emergence of autonomy, assertiveness, advocacy and accountability. An original table of contemporary attributes, which is congruent with a neo Aristotelian virtue ethical approach, is arranged in themes of Intellectual and Practical Attributes, Dispositional Attributes and Moral Attributes. A framework for professional practice, the ‘Four As’ is then extrapolated from these themes. These four key professional attributes, autonomy, advocacy, accountability and assertiveness, along with the virtues listed in the themes, exemplify the ‘good’ nurse and are identified as the linchpins of modern professional ethics and good conduct.

Social Risk of Public Spending Cuts in Scotland: Local Authority Experiences

This paper relates to work supported by the Joseph Rowntree Foundation which examines the way Scottish Local Authorities have approached budget cuts (Asenova, et. al., 2013). Starting with a discussion of notions of social risk, we discuss the heightened challenges faced by local authorities. We note that the literature on public sector innovation predict such pressures would cause local authorities to engage in short term decision making and adopt a static coping approach to risk mitigation which is likely to stifle innovation and obstruct the creation of more coherent and resilient localities. Although we find this to have happened in some areas, we discuss two cases where these challenges have promoted innovative and inclusive approaches to service re-design and delivery.

Évaluation in vitro de la stérilisation au peroxyde d'hydrogène sur les propriétés biologiques de prothèses utilisées lors de stabilisation du genou chez le chien

Objectif—Comparer les effets de la stérilisation au plasma de gaz de peroxyde d’hydrogène (HPGP) à l’oxyde d’éthylène (EO) et à la vapeur (ST) sur les propriétés physico-chimiques et d’adhésion bactérienne de fils de nylon et de polyéthylène. Design expérimental—Etude in vitro. Matériel—Des brins non stérilisés, stérilisés au HPGP, à l’EO et ST; de fil nylon leader (FNL), de fil de nylon pêche (FNP) et de fil de polyéthylène (PE) ont été utilisés. Méthodes—Une analyse de surface au spectroscope photo-électronique à rayons X (XPS), une mesure de l’angle de contact, une analyse par microscopie à force atomique (AFM) et l’adhésion bactérienne de Staphylococcus intermedius et d’Escherichia Coli ont été testés sur les brins. Résultats—Une oxydation de la surface de tous les échantillons stérilisés a été observée quelque soit la méthode de stérilisation. La stérilisation a augmenté significativement l’angle de contact pour tous les types de fil quelque soit la méthode. La rugosité n’a pas été affectée significativement par la méthode de stérilisation pour le FNL et FNP. L’adhésion bactérienne a été affectée significativement par la méthode de stérilisation. Le PE a un angle de contact, une rugosité et une adhésion bactérienne significativement plus élevée que le FNL et FNP, peu importe la méthode de stérilisation. Conclusion—La stérilisation au HPGP constitue une alternative intéressante à la vapeur et l’EO. Le PE n’est peut être pas un matériel idéal par sa capacité d’adhésion bactérienne. De futures études sont nécessaires pour déterminer la signification clinique de ces trouvailles.

Imagerie multimodale (radiographie numérique, tomodensitométrie, résonance magnétique à 1,5 Tesla) pour l'évaluation des lésions d'ostéoarthrose

Mémoire numérisé par la Division de la gestion de documents et des archives de l'Université de Montréal

Développement du cartilage articulaire équin du fœtus à l’adulte : imagerie par résonance magnétique et microscopie en lumière polarisée

La structure du cartilage articulaire adulte est caractérisée par la présence de couches créées par l’orientation des fibres de collagène (Benninghoff, 1925). Avant de présenter la structure adulte classique en arcades “de Benninghoff”, le cartilage subit une série de changements au cours de sa maturation (Julkunen et al., 2010; Lecocq et al., 2008). Toutefois, un faible nombre d’études s’est intéressé à la structure du collagène du cartilage articulaire in utero. Notre objectif était d’étudier la maturation de la surface articulaire de l’épiphyse fémorale distale chez le cheval, en employant à la fois l’imagerie par résonance magnétique (IRM) et la microscopie en lumière polarisée après coloration au rouge picrosirius, au niveau de sites utilisés dans les études de réparation tissulaire et de sites prédisposés à l’ostéochondrose (OC). Le but était de décrire le développement normal du réseau de collagène et la relation entre les images IRM et la structure histologique. Des sections provenant de cinq sites de l’épiphyse fémorale distale de 14 fœtus et 10 poulains et adultes ont été colorées au rouge picrosirius, après que le grasset ait été imagé par IRM, dans l’optique de visualiser l’agencement des fibres de collagène de type II. Les deux modalités utilisées, IRM et microscopie en lumière polarisée, ont démontré la mise en place progressive d’une structure en couches du réseau de collagène, avant la naissance et la mise en charge de l’articulation.

Étude comparative de l'imagerie dans l'évaluation de l'ostéoarthrose du grasset chez le cheval

Les objectifs de cette étude étaient (1) de décrire la localisation et la sévérité des lésions d’ostéoarthrose (OA) chroniques acquises naturellement au niveau du grasset équin grâce à l’échographie (US), la radiographie (XR), la tomodensitométrie (CT) et l’évaluation macroscopique (ME), (2) de comparer la performance diagnostique de chacune des modalities d’imagerie avec ME et (3) d’évaluer quantitativement la densité osseuse sous-chondrale lors d’OA du grasset chez le cheval à la tomodensitométrie. Des évaluations post mortem radiographique, tomodensitométrique et échographique ont été réalisées sur 23 grassets cadavériques et comparées à l’évaluation macroscopique. Des associations significatives ont été notées entre le «osteophytes global score» de toutes les modalités (US, p=0.04; XR, p=0.005; CT, p˂0.0001) et ME. De plus, la tomodensitométrie a démontré la plus forte association. Les ostéophytes étaient principalement localisés au niveau de l’articulation fémorotibiale médiale et cette articulation présentait également les scores d’ostéophytes les plus sévères. Un patron spécifique d’ostéophytes associé à l’insertion de la capsule articulaire sur le condyle fémoral médial a été mis en évidence. La nouvelle projection radiographique (Ca10Pr5L-CrDiMO) a été utile dans la détection des ostéophytes de la région intercondylaire. Les grades d’ostéophytes (0-3) ne différaient pas significativement selon la modalité dans la majorité des sites. La faible sensibilité/spécificité a indiqué que la sclérose de l’os sous-chondral et l’applatissement des condyles fémoraux ne semblent pas être des indicateurs fiables d’OA du grasset équin. L’OA du grasset équin est associée à une réduction de la densité osseuse sous-chondrale et des sites spécifiques de résorption/kystes sous-chondraux ont été notés chez certains spécimens.

The work of psychologists in social policy in Brazil

This study verses on the meeting of psychology with the social policy area. The objective is to discuss how psychologists that work in the Basic Health Units and in the Social Assistance Reference Centers experience their daily practices. Using the interview and participant observation methods, we investigated the modes of action of 13 psychologists involved in these service units. The results indicate that because these contexts are adverse to the traditional forms of action, many professionals experience daily strangeness and discomfort, resulting from their encounters with limiting situations of difficult management. Furthermore, we observed practices and experiences that were marked by feelings of compassion, pity, and resentment. We consider, finally, that the encounter between psychology and social policies requires flexibility in traditional acting modes as well as the pursuit of strategies that consider cultural contexts characteristics, avoiding capture, fatigue and saturation process that stifle the worker.

La Sostenibilidad Fiscal, el triunfo del mercado sobre los derechos.

La modificación a la Constitución Política de Colombia, que agregó el criterio de sostenibilidad fiscal, que tendrá que ser aplicado en todas las actuaciones del Estado, se implementó como forma de aplacar el gasto del Estado con miras a lograr dos objetivos que son: el de mantener el estado de la deuda pública a topes manejables, es decir, reducir la deuda y poder tener una estabilidad macroeconómica; según el gobierno nacional con estos dos pilares se asegurará un clima estable para la inversión extranjera en el territorio nacional augurando un auge económico sostenido y el bienestar general de los nacionales a futuro. En la presente monografía se realiza un análisis juicioso de dicho criterio, sus motivaciones económicas, la forma de su aprobación en el congreso de la república y el papel del Estado colombiano en la formulación del acto legislativo, así como las consecuencias que se suscitan en este una vez aprobado el criterio de sostenibilidad fiscal. En el transcurso de la monografía se podrá entender que es el criterio de sostenibilidad fiscal consecuencia de un proceso de globalización económica y una medida que inserta a la economía colombiana en esa tendencia mundial de libre flujo de bienes, capitales y servicios, que ha demostrado sólo beneficiar a grandes emporios económicos, multinacionales, transnacionales y sectores productivos de países potencias en detrimento de sectores económicos de los otros países, se concluye así que el criterio de sostenibilidad fiscal no es una buena decisión e implica un cambio fundamental del modelo de Estado que hace colapsar la economía nacional y de paso se da un golpe de gracia al cumplimiento de derechos fundamentales.

Use of extensible internal device in the femur of young dogs

An extensible internal device (EID) was developed to preserve growth plate during the treatment of fracture complications or segmental bone loss from tumour resection in children. Since this type of extensible, trans-physeal, internal fixation device has only been used in a few paediatric cases; the aim of this study was to evaluate an in vivo canine study, a surgical application of this device, and its interference with longitudinal growth of the non-fractured distal femur. Ton clinically healthy two- to three-month-old poodles weighing 1.5-2.3 kg were used. Following a medial approach to the right distal femur, one extremity of the EID, similar to a T-plate, was fixed in the femoral condyle with two cortical screws placed below the growth plate. The other extremity, consisting of an adaptable brim with two screw holes and a plate guide, was fixed in the third distal of the femoral diaphysis with two cortical screws. The EID was removed 180 days after application. All of the dogs demonstrated full weight-bearing after surgery. The values of thigh and stifle circumferences, and stifle joint motion range did not show any difference between operated and control hindlimbs. The plate slid in the device according to longitudinal bone growth, in all but one dog. In this dog, a 10.5% shortening of the femoral shaft was observed due to a lack of EID sliding. The other dogs had the some longitudinal lengths in both femurs. The EID permits longitudinal bone growth without blocking the distal femur growth plate if appropriately placed.

Epidural analgesia with morphine or buprenorphine in ponies with lipopolysaccharide (LPS)-induced carpal synovitis

This study evaluated the analgesia effects of the epidural administration of 0.1 mg/kg bodyweight (BW) of morphine or 5 mu g/kg BW of buprenorphine in ponies with radiocarpal joint synovitis. Six ponies were submitted to 3 epidural treatments: the control group (C) received 0.15 mL/kg BW of a 0.9% sodium chloride (NaCl) solution; group M was administered 0.1 mg/kg BW of morphine; and group B was administered 5 mu g/kg BW of buprenorphine, both diluted in 0.9% NaCl to a total volume of 0.15 mL/kg BW administered epidurally at 10 s/mL. The synovitis model was induced by injecting 0.5 ng of lipopolysaccharide (LPS) in the left or right radiocarpal joint. An epidural catheter was later introduced in the lumbosacral space and advanced up to the thoracolumbar level. The treatment started 6 h after synovitis induction. Lameness, maximum angle of carpal flexion, heart rate, systolic arterial pressure, respiratory rate, temperature, and intestinal motility were evaluated before LPS injection (baseline), 6 h after LPS injection (time 0), and 0.5, 1, 2, 4, 6, 8, 10, 12, 16, 20, and 24 h after treatments. Although the model of synovitis produced clear clinical signs of inflammation, the lameness scores in group C were different from the baseline for only up to 12 h. Both morphine and buprenorphine showed a reduction in the degree of lameness starting at 0.5 and 6 h, respectively. Reduced intestinal motility was observed at 0.5 h in group M and at 0.5 to 1 h in group B. Epidural morphine was a more effective analgesic that lasted for more than 12 h and without side effects. It was concluded that morphine would be a valuable analgesic option to alleviate joint pain in the thoracic limbs in ponies.

Estenose da fossa intercondilar após estabilização articular com retalho de fáscia lata em cães

Determinaram-se os índices de largura da fossa intercondilar (FI), após transecção do ligamento cruzado cranial em nove cães adultos submetidos à estabilização articular com retalho de fáscia lata. Os joelhos foram alocados em dois grupos, sendo o joelho direito (GI) submetido à incisuroplastia troclear (ITR) e posterior estabilização articular, e o joelho esquerdo submetido somente à substituição ligamentar (GC). Cada grupo foi dividido em três subgrupos correspondentes aos momentos de eutanásia aos 30, 90 e 180 dias de pós-operatório. Os índices de largura da FI foram determinados, macroscópica e radiograficamente, pela mensuração da abertura cranial da FI nos terços cranial, médio e caudal, e indexados em relação à largura epicondilar. Observou-se aumento significativo dos índices macroscópicos e radiográficos nas articulações do GI, sendo estes estatisticamente diferentes daqueles das articulações de GC. Não foi observada estenose intercondilar nos joelhos de GC após a estabilização articular. Conclui-se que a estabilização articular com retalho de fáscia lata preveniu a estenose da fossa intercondilar, e que a ITR promoveu o alargamento permanente dessa estrutura.
