Total Knee Arthroplasty: Patellar Replacement’s Influence in Patient Quality of Life Postoperatively  [PDF]
Carlos Roberto Schwartsmann, Gabriel Severo da Silva, Ivan Fadanelli Simionato, Flávia Magalh?es Nunes, Henrique Lammerhirt, Joo Pedro Farina Brunelli, Leandro de Freitas Spinelli
Open Journal of Orthopedics (OJO) , 2017, DOI: 10.4236/ojo.2017.78024
Abstract: Objective: To study the influence of patellar resurfacing on quality of life under a standardised score. The chosen score was the Knee Society Score (KSS), which considers range of motion, pain, contractors, alignment and stability. Methods: Retrospective review of 60 patients submitted to total knee arthroplasty (TKA) was divided into two groups: with patellar resurfacing (PR) and without patellar resurfacing (NPR). We reviewed data from these patients containing the KSS, which are routinely used in our service. Data were analysed from 2013 to 2014, with a minimal patient follow-up of 18 months. Results: There were no unsatisfactory scores in our study. Total scores (KSS) were similar between the groups (mean KSS: PR = 88.36 ± 9.64; NPR = 84.26 ± 9.44 [p = 0.1]). While stratifying into groups (poor, fair, good, excellent), we found excellent results in 84.8% of PR versus 59.3% NPR (p = 0.056). These data did not reach statistical significance and can therefore be considered a coincidental result. Conclusion: Although these results did not show statistical significance (p = 0.056), patellar resurfacing patients tend to get more “excellent” results after 18 months of follow-up in quality of life when evaluated by KSS. Perhaps a larger amount of patients would suffice to acquire statistical significance in a future study.

Open Journal of Orthopedics (OJO) , 2019, DOI: 10.4236/ojo.2019.92003
Abstract: Introduction: Total knee arthroplasty, being a major surgery, carries a risk of post-operative deep vein thrombosis (DVT). The main objective of the present study was to elucidate the association of clinical, laboratory, and echographic findings with the occurrence of DVT. Patients and Methods: The present study was prospective and non-randomized, with restricted exclusion criteria. Forty patients were submitted to total knee arthroplasty due to osteoarthritis. Patients were clinically evaluated by laboratory tests, assessment of pain and calf circumference, and the presence of Homans’ sign. Echo Doppler was performed in each patient on postoperative day 7. The echographic evaluation divided the patients into two groups: positive (G1) and negative for thrombosis (G2). All patients received prophylactic heparin during the 7-day hospital admission. Results: Eleven patients complained of pain (analgesic medication was used during the entire admission). Leg circumference variation from the pre-operative period to post-operative day 7 was: G1, 1.70 ± 1.12 cm and G2, 0.68 ± 1.25 cm (p = 0.03). Homans’ sign was considered positive in 10 patients. Echographic evaluation was positive in 11 patients (27.5%). No cases of pulmonary embolism, infection, or death were observed. Conclusions: The incidence of DVT was 27.5%, with an increase in leg circumference being the main predictive factor (p = 0.03).

Abstract: Background. Stroke is a leading cause of mortality and disability in Brazil and around the world. Cardioembolism is responsible for nearly 30% of the origins of ischemic stroke. Methods. We analyzed data of 256 patients with cardioembolic ischemic stroke (according to TOAST classification) who were admitted into the Hospital S?o Lucas-PUCRS from October 2011 to January 2014. The cardioembolic subtype was divided into six subgroups: arrhythmias, valvular heart disease, coronary artery disease, cardiomyopathy, septal abnormalities, and intracardiac injuries. The prevalence of the most important cardiovascular risk factors and medications in use for prevention of systemic embolism by the time of hospital admission was analyzed in each patient. Results. Among 256 patients aged 60.2 +/? 6.9 years, 132 males, arrhythmias were the most common cause of cardioembolism corresponding to 50.7%, followed by valvular heart disease (17.5%) and coronary artery disease (16%). Hypertension (61.7%) and dyslipidemia (43.7%) were the most common risk factors. Less than 50% of patients with arrhythmias were using oral anticoagulants. Conclusions. Identifying the prevalence of cardioembolic stroke sources subgroups has become an increasingly important role since the introduction of new oral anticoagulants. In this study, arrhythmias (especially atrial fibrillation) were the main cause of cardioembolism. 1. Introduction Stroke is the leading cause of mortality and disability in Brazil and South America. However, there is little knowledge about stroke epidemiology, stroke subtypes, and risk factors in Latin America [1–3]. Basically strokes can be divided into ischemic (85%) and hemorrhagic (15%). The clinical characteristics of stroke vary according to etiology and risk factors. To facilitate and standardize the classification of stroke subtypes, it was developed in 1993—the TOAST (Trial of Org 10172 in Acute Stroke Treatment) classification which divides the ischemic stroke into five subtypes: large-artery atherosclerosis, cardioembolism, small-vessel occlusion, stroke of other determined etiology, and stroke of undetermined etiology. Knowledge of the etiology of ischemic events is essential for correct treatment and secondary prevention to improve the best patient outcomes [4, 5]. In the south of Brazil, the most important source of ischemic stroke is large-artery atherosclerosis followed by cardioembolism and small-vessel disease. Cardioembolism is responsible for nearly 30% of the origins of ischemic stroke [2, 6, 7]. Cardioembolism can be subdivided into six subgroups:

Abstract: Given a bounded linear operator T:LPO(ℝn)→Lp1(ℝn), we state conditions under which T defines a bounded operator between corresponding pairs of Lp(ℝn;ιq) spaces and Triebel-Lizorkin spaces Fp,qs(ℝn). Applications are given to linear parabolic equations and to Schrödinger semigroups.
O retorno do escravismo em meados do século XIX
Marques,Joo Pedro;

Abstract: in the final quarter of the nineteenth century, portugal and other european countries took part in the conquest and occupation of the african hinterland and based their exploitation of the new territories on forms of exploiting labour which were very close to slavery - which had supposedly been abolished. this article shows how this paradox arose in the decades of the 1850s and 60s, and how it was the outcome of changes in the way the western peoples came to see the negro and the problem of labour in the tropics.

Avalia??o: Revista da Avalia??o da Educa??o Superior (Campinas) , 2010, DOI: 10.1590/S1414-40772010000100002
Abstract: community and communitarian are widely used terms, in the past as well as in the present, in the discourse of organizations, institutions and social actors, and are characterized by their polysemous qualities. as with the brazilian case, distinct initiatives have invoked the communitarian nature throughout history. in common, the self-reference to the collective interest and not being owned by the state. to distinguish them, the varied ideological perspectives, the different ways of interacting with the state and society, the internal forms of organization. the mobilization of the communitarian institutions for higher education in brazil in favor of their own legal framework, strengthens the communitarian discourse under the not state-owned public perspective. this text approaches the main experiences of the communitarian in brazilian education and discusses the meaning of the communitarian as a public and yet not state-owned institution.

Abstract: this article deals with the vocational integration dialectics of senior executives in companies with differing innovation capacities. the aim was to identify the extent to which the vocational integration of senior executives is influenced by the various business contexts in which it occurs. the author also tries to determine whether the factors that generate these unequal possibilities do indeed include differing degrees of innovation capacity of this type. amongst the various aspects that determine the way in which senior executives manage, he particularly comes across formats that reveal the existence of specific strategies. these are at the source of two very contrasting vocational integration models: that of "qualifying vocational integration", and that of "non-qualifying vocational integration".

Abstract: The European construction industry is currently experiencing great difficulties and challenges but in Portugal the sector is facing a critical moment which will decisively impact its future. Along with the redefinition of its legal framework, so as to make it more efficient and bring it up to date, the sector is going through stagnation in the private market and a slump in the public construction market, mostly on account of the current state of economy country. Furthermore, the lack of accomplishment of cost, time, safety, and quality, has been recurrently mentioned in the press and in technical literature as one of the main causes for thelack of competitiveness of sector. The poor quality of project designs has been considered as main reason for the recurrent time and cost overruns. Previous studies have often found that designs contain a lot of errors and omissions. This paper wills critically to discuss the problem of poor quality design in Portugal using literature and data from a set of interviews with expert construction managers. The main reasons for the poor quality of project designs have been established from the outcomes of a national survey undertaken and a series of interviews of experts. Some measures that would lessen the problem have been identified.
