Cemented total hip arthroplasty with retention of some existing hardware

We report a case of a 63-year-old man who presented an end stage hip osteoarthritis 42 years after a proximal femoral osteotomy performed for the treatment of an intracapsular femoral neck fracture. A cemented total hip arthroplasty was implanted using a standard posterior approach. The osteotomy hardware was totally covered with a new cortical bone formation. A layer of bone tissue was removed, the screw heads were broken and the nail plate was also removed. The screw threaded portions were retained because they did not interfere with cemented femoral stem implantation. Fourteen years after total hip arthroplasty, the patient reported no pain and expressed high satisfaction with the surgery. The hip radiograph showed wear of the polyethylene cup and no periprosthetic osteolysis. Retention of hardware can be considered, especially in patients who have had hardware for several years, without any negative symptoms

A linkage map for the B-genome of Arachis (Fabaceae) and its synteny to the A-genome

<p>Abstract</p> <p>Background</p> <p><it>Arachis hypogaea </it>(peanut) is an important crop worldwide, being mostly used for edible oil production, direct consumption and animal feed. Cultivated peanut is an allotetraploid species with two different genome components, A and B. Genetic linkage maps can greatly assist molecular breeding and genomic studies. However, the development of linkage maps for <it>A. hypogaea </it>is difficult because it has very low levels of polymorphism. This can be overcome by the utilization of wild species of <it>Arachis</it>, which present the A- and B-genomes in the diploid state, and show high levels of genetic variability.</p> <p>Results</p> <p>In this work, we constructed a B-genome linkage map, which will complement the previously published map for the A-genome of <it>Arachis</it>, and produced an entire framework for the tetraploid genome. This map is based on an F₂population of 93 individuals obtained from the cross between the diploid <it>A. ipaënsis </it>(K30076) and the closely related <it>A. magna </it>(K30097), the former species being the most probable B genome donor to cultivated peanut. In spite of being classified as different species, the parents showed high crossability and relatively low polymorphism (22.3%), compared to other interspecific crosses. The map has 10 linkage groups, with 149 loci spanning a total map distance of 1,294 cM. The microsatellite markers utilized, developed for other <it>Arachis </it>species, showed high transferability (81.7%). Segregation distortion was 21.5%. This B-genome map was compared to the A-genome map using 51 common markers, revealing a high degree of synteny between both genomes.</p> <p>Conclusion</p> <p>The development of genetic maps for <it>Arachis </it>diploid wild species with A- and B-genomes effectively provides a genetic map for the tetraploid cultivated peanut in two separate diploid components and is a significant advance towards the construction of a transferable reference map for <it>Arachis</it>. Additionally, we were able to identify affinities of some <it>Arachis </it>linkage groups with <it>Medicago truncatula</it>, which will allow the transfer of information from the nearly-complete genome sequences of this model legume to the peanut crop.</p

Avaliação da intensidade do treinamento técnico-tático e da fadiga causada em jogadores de futebol da categoria sub-20

Resumo Visto que o calendário atual do futebol não disponibiliza um tempo hábil para a devida recuperação dos atletas, fadiga e recuperação têm sido amplamente estudadas por pesquisadores. O que levou ao surgimento de alguns instrumentos com o propósito de fornecer informações e dar suporte aos profissionais visando a alta performance. O objetivo deste estudo foi analisar a intensidade do Treinamento Técnico-tático e a fadiga causada em jogadores de futebol da categoria sub-20, através do desempenho em testes de salto vertical e horizontal e da percepção subjetiva de esforço da sessão (PSE da sessão). Os jogadores (n = 25) realizaram o salto vertical contra movimento (SCM) e horizontal (SH), antes e após a uma sessão de Treinamento Técnico-tático (TTT), sendo a intensidade avaliada pela Escala de Borg (CR 10). O SCM não apresentou diferença significativa (p > 0,05), enquanto que o SH foi maior no Pós-TTT em relação ao Pré-TTT (p = 0,02). Quanto a PSE da sessão, 92% dos jogadores classificaram a intensidade do TTT como sendo de fácil à moderada. Os resultados deste estudo indicam que o TTT de baixa intensidade não compromete a potência nos testes de salto vertical e horizontal. Sugere-se que além de proporcionar a operacionalização dos padrões de comportamento táticos coletivos, o TTT de baixa intensidade possa ser utilizado em treinamentos de caráter regenerativo ou em momentos que o calendário esportivo não possibilite a recuperação completa dos jogadores

Biological variation in Anopheles darlingi root

Behavioural variation in the South American malaria vector Anopheles darlingi is described. At the centre of its distribution, in forest areas close to the city of Manaus, Brazil, it is primarily exophagic and exophilic. Mosquitoes from this area are chromosomally diverse. Towards the northern edge of its distribution (in Guyana and Venezuela) it is more endophagic and less diverse chromosomally. Similarly in the south (in the state of Minas Gerais) it is less polymorphic. In this area, however, it is primarily zoophilic and exophagic. Evidence is presented that female wing size may vary between populations. The possibility that this widely distributed species may be a complex could have important implications for future malaria control schemes

Impact of promoting self-care in nursing workload

Abstract OBJECTIVES To assess the impact of promoting self-care in nursing workload and associate it to the variables: age, gender, socioeconomic status, education, marital status and number of children of caregivers. METHODS Prospective study with 31 children and their caregivers. Participants were assessed at two moments, 1st and 2nd hospitalization, the nursing workload was measured by the Nursing Activities Score (NAS). RESULTS The mean NAS in the 1st hospitalization was 60.9% and in the 2nd hospitalization was 41.6%, that is, 14.6 and 9.9 hours of nursing, respectively. The nursing workload on the first day of hospitalization was higher compared to the last day, both for the 1st (p<0.001) and for the 2nd hospitalization (p<0.001), and higher in the first (p<0.001) and in the last day (p=0.025) in the 1st hospitalization. Comparing the 1st hospitalization to the 2nd hospitalization, the first was higher (p<0.001), and NAS items related to the training of self-care was influenced (p<0.001). CONCLUSION The nursing workload associated to self-care promotion corresponded to 14.6 hours and was higher than determined by the existing legislation
