Partimos do pressuposto de que o futebol é um dos esportes que tem tido um papel importante nas sociedades modernas como um dos poucos fatores de excitação, além de funcionar como equilibrador de tensões psicossociais. A violência, principalmente a física, era tolerada e muitas vezes desejada pelos ingleses praticantes e por aqueles que assistiam ao antigo futebol na Idade Média, naquele momento um jogo popular. Através da esportivização dos passatempos ocorrida na Europa - na esteira da industrialização – os códigos de conduta social se transformaram, levando a um processo de sensibilização das sociedades. Esta dinâmica proliferou outras formas de violências no futebol, tais como a simbólica, a racista e a de gênero. O futebol chegou ao Brasil somente no final do século XIX como um esporte de elite, mas rapidamente foi recepcionado pelos menos favorecidos, e hoje é um produto de consumo que movimenta fortunas incalculáveis. Desde a sua profissionalização até a recente espetacularização, o futebol sempre apresentou episódios de violências, dentro e fora de campo. Entretanto somente após quinze anos da Constituição Federal os legisladores ordinários aprovaram uma lei – Estatuto de Defesa do Torcedor (EDT) - que deveria defender aquele que banca o espetáculo. Na tentativa de produzir um sentimento de “paz nos estádios”...

A composição química da água de coco, com altos teores de açúcares e sais minerais, pode propiciar condições favoráveis ao desenvolvimento microbiano, principalmente das bactérias. O processamento industrial da água de coco virtualmente elimina todos os microrganismos que possam causar algum tipo de doença humana. Entretanto, as características sensoriais da água de coco in natura ou envasada a fresco são consideradas superiores à da bebida pasteurizada ou comercialmente estéril. Além disso, a bebida fresca é mais barata que a industrializada. A segurança dos produtos frescos depende fundamentalmente da prevenção de sua contaminação, associada a uma refrigeração adequada durante o transporte e armazenamento. Os objetivos deste estudo foram os seguintes: i) avaliar a eficácia da imersão em água e a sanitização com hipoclorito de sódio, ácido peracético e vapor superaquecido, na descontaminação da superfície do coco verde, utilizando-se Listeria monocytogenes como microrganismo-teste; ii) desenvolver a flambagem como tratamento de descontaminação da superfície do coco verde; e iii) estudar o comportamento de L. monocytogenes inoculado experimentalmente em água de coco fresca mantida sob diferentes condições de temperatura. Os tratamentos químicos consistiram na imersão dos frutos em água destilada estéril...

Adult diabetic patients admitted to our Diabetes Center from September 1996 to January 1998 for severe, limb-threatening foot infection were consecutively enrolled in a prospective, randomized, controlled clinical study aimed at assessing the safety and efficacy of recombinant human granulocyte colony-stimulating factor (G-CSF) (lenograstim) as an adjunctive therapy for the standard treatment of diabetic foot infection. Forty patients, all of whom displayed evidence of osteomyelitis and long-standing ulcer infection, were randomized 1:1 to receive either conventional treatment (i.e., antimicrobial therapy plus local treatment) or conventional therapy plus 263 μg of G-CSF subcutaneously daily for 21 days. The empiric antibiotic treatment (a combination of ciprofloxacin plus clindamycin) was further adjusted, when necessary, according to the results of cultures and sensitivity testing. Microbiologic assessment of foot ulcers was performed by both deep-tissue biopsy and swab cultures, performed at enrollment and on days 7 and 21 thereafter. Patients were monitored for 6 months; the major endpoints (i.e., cure, improvement, failure, and amputation) were blindly assessed at weeks 3 and 9. At enrollment, both patient groups were comparable in terms of both demographic and clinical data. None of the G-CSF-treated patients experienced either local or systemic adverse effects. At the 3- and 9-week assessments...

Mechanical prophylaxis with foot pumps provides an interesting alternative to chemical agents in the prevention of thromboembolic disease following major orthopaedic surgical procedures. Recent studies have suggested that the simultaneous use of graduated compression stockings (GCS) may hinder the pneumatic compression effect of foot pumps. The hypothesis of this prospective study was that the use of foot pumps without GCS does not affect the efficacy of deep-vein thrombosis (DVT) prophylaxis and improves patient compliance. A total of 846 consecutive patients admitted at a single institution undergoing total hip (THR) or knee replacement (TKR) were included in the study. The A-V Impulse System foot-pump unit (Orthofix Vascular Novamedix, Andover, UK) was used in all patients. Of these 846 patients, 46 discontinued the use of foot pumps, leaving 400 patients who received foot pumps in combination with GCS and 400 patients with foot pumps alone. Eleven patients of the stocking group (2.7%) and nine patients of the no-stocking group (2.3%) developed postoperative symptomatic DVT (p = 0.07). DVT was more frequent in TKR (10/364; 2.7%) than in THR (10/436; 2.3%). Non-fatal pulmonary embolism occurred in four of the 20 patients with symptomatic DVT...

Our objective was to create a practical standardized database of clinically relevant variables in the care of patients with diabetes and foot ulcers. Numerical clinical variables such as age, baseline laboratory values, and wound area were extracted from the wound electronic medical record (WEMR). A coding system was developed to translate narrative data, culture, and pathology reports into discrete, quantifiable variables. Using data extracted from the WEMR, a diabetic foot ulcer-specific database incorporated the following tables: (1) demographics, medical history, and baseline laboratory values; (2) vascular testing data; (3) radiology data; (4) wound characteristics; and (5) wound debridement data including pathology, culture results, and amputation data. The database contains variables that can be easily exported for analysis. Amputation was studied in 146 patients who had at least two visits (e.g., two entries in the database). Analysis revealed that 19 (13%) patients underwent 32 amputations (nine major and 23 minor) in 23 limbs. There was a decreased risk of amputation, 0.87 (0.78, 1.00), using a proportional hazards model, associated with an increased number of visits and entries in the WEMR. Further analysis revealed no significant difference in age...

Effects of a topical cream containing P. amboinicus (Lour.) Spreng. (Lamiaceae) and C. asiatica (L.) Urban (Umbelliferae) were evaluated and compared to effects of hydrocolloid fiber wound dressing for diabetic foot ulcers. A single-center, randomized, controlled, open-label study was conducted. Twenty-four type 1 or type 2 diabetes patients aged 20 years or older with Wagner grade 3 foot ulcers postsurgical debridement were enrolled between October 2008 and December 2009. Twelve randomly assigned patients were treated with WH-1 cream containing P. amboinicus and C. asiatica twice daily for two weeks. Another 12 patients were treated with hydrocolloid fiber dressings changed at 7 days or when clinically indicated. Wound condition and safety were assessed at days 7 and 14 and results were compared between groups. No statistically significant differences were seen in percent changes in wound size at 7- and 14-day assessments of WH-1 cream and hydrocolloid dressing groups. A slightly higher proportion of patients in the WH-1 cream group (10 of 12; 90.9%) showed Wagner grade improvement compared to the hydrocolloid fiber dressing group but without statistical significance. For treating diabetic foot ulcers, P. amboinicus and C. asiatica cream is a safe alternative to hydrocolloid fiber dressing without significant difference in effectiveness.

Patient safety regarding wrong site surgery has been one of the priority issues in surgical fields including that of spine care. Since the wrong-side surgery in the DM foot patient was reported on a public mass media in 1996, the wrong-site surgery issue has attracted wide public interest as regarding patient safety. Despite the many wrong-site surgery prevention campaigns in spine care such as the operate through your initial program by the Canadian Orthopaedic Association, the sign your site program by the American Academy of Orthopedic Surgeon, the sign, mark and X-ray program by the North American Spine Society, and the Universal Protocol program by the Joint Commission, the incidence of wrong-site surgery has not decreased. To prevent wrong-site surgery in spine surgeries, the spine surgeons must put patient safety first, complying with the hospital policies regarding patient safety. In the operating rooms, the surgeons need to do their best to level the hierarchy, enabling all to speak up if any patient safety concerns are noted. Changing the operating room culture is the essential part of the patient safety concerning spine surgery.

Inactivated foot-and-mouth disease (FMD) vaccines are currently used worldwide. With the emergence of various FMD virus serotypes and subtypes, vaccines must become more suitable for field-based uses under the current circumstances in terms of the fast and proper selection of vaccine strains, an extended vaccine development period for new viruses, protecting against the risk of virus leakage during vaccine manufacture, counteracting the delayed onset of immune response, counteracting shorter durations of immunity, and the accurate serological differentiation of infected and vaccinated animals and multiple vaccination. The quality of vaccines should then be improved to effectively control FMD outbreaks and minimize the problems that can arise among livestock after vaccinations. Vaccine improvement should be based on using attenuated virus strains with high levels of safety. Moreover, when vaccines are urgently required for newly spread field strains, the seed viruses for new vaccines should be developed for only a short period. Improved vaccines should offer superior immunization to all susceptible animals including cattle and swine. In addition, they should have highly protective effects without persistent infection. In this way, if vaccines are developed using new methods such as reverse genetics or vector vaccine technology...

Objective. To compare the effects of two types of ankle-foot orthoses on gait of patients with cerebrovascular accident (CVA) and to evaluate their preference in using each AFO type. Design. Thirty individuals with acute hemiparetic CVA were tested without an AFO, with an off-the-shelf carbon AFO (C-AFO), and with a custom plastic AFO (P-AFO) in random order at the time of initial orthotic fitting. Gait velocity, cadence, stride length, and step length were collected using an electronic walkway and the subjects were surveyed about their perceptions of each device. Results. Subjects walked significantly faster, with a higher cadence, longer stride, and step lengths, when using either the P-AFO or the C-AFO as compared to no AFO (P < 0.05). No significant difference was observed between gait parameters of the two AFOs. However, the subjects demonstrated a statistically significant preference of using P-AFO in relation to their balance, confidence, and sense of safety during ambulation (P < 0.05). Moreover, if they had a choice, 50.87 ± 14.7% of the participants preferred the P-AFO and 23.56 ± 9.70% preferred the C-AFO. Conclusions. AFO use significantly improved gait in patients with acute CVA. The majority of users preferred the P-AFO over the Cf-AFO especially when asked about balance and sense of safety.

Nonhealing neuropathic foot ulcers remain a significant problem in individuals with diabetes. The gap-junctional protein connexin43 (Cx43) has roles in dermal wound healing and targeting Cx43 signaling accelerates wound reepithelialization. In a prospective, randomized, multi-center clinical trial we evaluated the efficacy and safety of a peptide mimetic of the C-terminus of Cx43, ACT1, in accelerating the healing of chronic diabetic foot ulcers (DFUs) when incorporated into standard of care protocols. Adults with DFUs of at least four weeks duration were randomized to receive standard of care with or without topical application of ACT1. Primary outcome was mean percent ulcer reepithelialization and safety variables included incidence of treatment related adverse events and detection of ACT1 immunogenicity. ACT1 treatment was associated with a significantly greater reduction in mean percent ulcer area from baseline to 12 weeks (72.1% vs. 57.1%; p = 0.03). Analysis of incidence and median time-to-complete-ulcer closure revealed that ACT1 treatment was associated with a greater percentage of participants that reached 100% ulcer reepitheliazation and a reduced median time-to-complete-ulcer closure. No adverse events reported were treatment related...

Although the history of ozone therapy dates back to the 19th century, its use has shown a rapid growth of interest in recent decades. Intralesional ozone injection is seldom performed and its safety has not yet been reliably assessed for the treatment of diabetic foot wounds. Herein, we describe a diabetic patient who developed severe foot necrosis and infection after receiving intralesional ozone injections for a non-healing wound.

Purpose: To report the results of a planned safety analysis from a phase III trial comparing capecitabine plus oxaliplatin (XELOX) with bolus fluorouracil/leucovorin (FU/LV) as adjuvant therapy for stage III colon cancer. Patients and Methods: Patients with stage III colon carcinoma were randomly assigned to receive either XELOX (intravenous oxaliplatin plus oral capecitabine; 3-week cycle for eight cycles) or standard intravenous bolus FU/LV administered as the Mayo Clinic (Mayo; Rochester, MN) or Roswell Park (RP; Buffalo, NY) regimen for a similar length of time. A total of 1,886 patients were randomly assigned. Results: The safety population comprised 1,864 patients, of whom 938 received XELOX and 926 received FU/LV. Most treatment-related adverse events (AEs) occurred at similar rates in both treatment arms. However, patients receiving XELOX experienced less all-grade diarrhea, alopecia, and more neurosensory toxicity, vomiting, and hand-foot syndrome than those patients receiving FU/LV. Compared with Mayo, XELOX showed fewer grade 3/4 hematologic AE and more grade 3/4 gastrointestinal AE. Compared with RP, XELOX showed less grade 3/4 gastrointestinal AE and more grade 3/4 hematologic AE. As expected grade 3/4 neurosensory toxicity and grade 3 hand-foot syndrome were higher with XELOX. Treatment-related mortality within 28 days from the last study dose was 0.6% in the XELOX group and 0.6% in the FU/LV group. Conclusion: XELOX has a manageable tolerability profile in the adjuvant setting. Efficacy data will be available within the next 24 months; Hans-Joachim Schmoll...

Effective off-loading is considered to be an important part of the successful clinical management of diabetic foot ulcers. The aim of this systematic review is to investigate the safety and effectiveness of different off-loading devices for the treatment of diabetic foot ulcers. The medical literature was extensively searched from January 1966 to May 2012. Systematic reviews and controlled studies that compared the use of different off-loading devices formed the evidence base. Studies were critically appraised to determine their risk of methodological bias, and data were extracted. Results were pooled using random effects meta-analysis and tested for heterogeneity. When compared with removable devices, non-removable off-loading devices were found, on average, to be more effective at promoting the healing of diabetic foot ulcers (RRp  = 1.43; 95% CI 1.11, 1.84; I(2)  = 66.9%; p = 0.001; k = 10). Analysis, stratified by type of removable device, did not detect a statistically significant difference between non-removable off-loading devices and removable cast walkers; however, on average non-removable off-loading devices performed better than therapeutic shoes at promoting the healing of diabetic foot ulcers (RRp  = 1.68; 95% CI 1.09...

Arbeitsschuhe stellen die mit Abstand am häufigsten getragenen Schuhe eines Industriearbeiters dar, weshalb es gerade bei diesen Schuhen wichtig ist, dass eine optimale Passform gewährleistet ist. In der vorliegenden Studie wurden bei 517 männlichen Industriearbeitern mit einer neuartigen Meßmethode, einem 3D-Scanner („Pedus 3D Foot Scanner“, Fa. Human Solutions GmbH), Fußvermessungen durchgeführt. Analog der Fußvermessung erfolgten auch Messungen an den für die Arbeitsschuhherstellung verwendeten Leisten, um einen entsprechenden Vergleich durchführen zu können. Anhand einer Evaluierung der gewonnenen Fußmaße konnte gezeigt werden, dass es mit einem einzigen Modell pro Fußweite und Schuhgröße nicht möglich ist, dem Anspruch gerecht zu werden, jedem Arbeiter optimal passende Sicherheitsschuhe anbieten zu können. Bei einer Vielzahl an Fußmaßen einer Schuhgröße variieren die Maße teils erheblich. Die Fußtypisierung mit Hilfe einer Clusteranalyse ergab, dass zwischen 3 Typen mit unterschiedlicher Ballenbreite, Ballen- bzw. Zehenlänge, Ballenwinkel und Fersenbreite unterschieden werden muss. Der Vergleich dieser Fußtypen mit den im Sicherheitsschuhbau eingesetzten Leisten zeigt die Defizite in der Passform auf. Eine zu große Ballenlänge...

Dynamisch-optische Oberflächenvermessung des plantaren Fußes Inhalt und Vorgehensweise Die Entwicklung eines zeitauflösenden dreidimensionalen Fußscanners unter Verwendung einer dynamisch-optischen Oberflächenvermessung stellt die primäre Zielsetzung dar. Dieses System wurde anschließend genutzt, um erste Erkenntnisse zur dynamischen Fußformveränderung über den Abrollvorgang zu gewinnen. Die Relevanz der Formveränderung, z.B. für die industrielle Schuhfertigung, wird in der Arbeit abschließend diskutiert. Hintergrund der Arbeit Bisherige kommerziell erhältliche Messsysteme sind auf die Erhebung der 3D-Fußmaße in der statischen Situation beschränkt. Es ist jedoch anzunehmen, dass die statische Fußform sich unter wechselnden Belastungssituationen, wie sie in der Dynamik vorkommen, entscheidend verändert. Die Anpassung der menschlichen Fußstruktur an die dynamischen Gegebenheiten ist bisher auf Grund fehlender Messtechnik nur unzureichend erforscht und berücksichtigt worden. Basierend auf diesen Defiziten, wurde das Ziel verfolgt, eine Messtechnik zu entwi-ckeln, die eine zuverlässige Erfassung der dreidimensionalen Oberflächeninformation der menschlichen Fußform während des Gehens ermöglicht. Mit Hilfe der Messtechnik wurden anschließend die Fußformveränderungen innerhalb des Abrollvorgangs sowie die Unterschiede zwischen der statischen und der dynamischen Fußform quantifiziert. Methode Es wurde ein plantares System...

The use of Personal Protective Equipment (PPE) has become a necessity in view of the number of accidents at work that occurred in the past years. The European Community (EU) and the member states are creating strategies aiming the increase of the use of PPE’s and consequently the decrease of the number of the accidents at work, decreasing also the number of injuries caused by them and their severity. In this paper, a brief review of safety footwear and its components will be presented focusing on penetration resistant inserts. Additionally, we present a project in development at University of Minho that aims to improve the existent shoes. This project aims the development of a new and innovative methodology for design a surface of a penetration resitant insert based in the anthropometry and biomechanical analysis of the foot. This methodology allows the design of a penetration resistant insert more comfortable and appellative than the already existent.; The financial funding from QREN, POFC, Vale Inovação Project nº2012/24148 is also gratefully acknowledged.

"Overall support for the pedestrian environment," or walk ability, has grown increasingly important as the world urbanizes and motorized modes threaten to displace or constrain travel on foot. This concern encompasses virtually every aspect of the pedestrian experience. Walk ability takes into account the quality of pedestrian facilities, roadway conditions, land use patterns, community support, security, and comfort for walking (Litman). Each of these facets of the pedestrian environment impacts the use of walking as a primary mode of transport. The complexity of the urban pedestrian environment naturally lends itself to micro-level analysis to locate the need for improvements; however, to gain an overview of a city, it is necessary to develop macro-level indicators that can identify the general state of the pedestrian environment. While these indicators cannot diagnose all walk ability problems, they can give a sense of how one urban area compares to another in similar circumstances and they have the potential for becoming an influential aspect of World Bank urban infrastructure diagnosis. Urban Transport indicators are being reviewed as one component of the current Transport Results Initiative which is led by the World Bank's central Transport Unit.

In society, personal load carriage systems (backpacks) are commonly used to transport loads by foot, however, they have also been implicated in causing injuries. The aim of this study was to develop a model for load carriage which could be used to determine safety limits in humans. To start, a number of experiments were conducted to determine the appropriateness of using pressure mapping technology to measure peak and mean pressures acting on humans during load carriage limits. Tests of accuracy and repeatability were performed using three common pressure mapping technologies: capacitance, piezoresistive and resistive ink. Pressure mapping was tested statically and dynamically on a human-like flat surface, as well as on human shoulder-shaped model. Error was found to be ≥ 20% on static flat and curved surfaces and it rose to 36-51% under dynamic conditions. Since pressure mapping would require significant modifications before it could be used to study human load carriage, a psychophysical approach was used instead. For this approach, an epidemiological study of pain was conducted based on 48 subjects who used multiple backpack designs to complete occupationally relevant tasks. As a result, pain trends and new methods of data analysis were identified that had potential use on human trials. In a final study...

This thesis describes the efforts to develop control strategies that use EMG signals from the anterior tibialis muscle to control ankle torque in an active ankle-foot orthosis. This would ultimately help rehabilitate persons affected by drop-foot gait, a condition which results in the loss of ability to dorsi-flex the ankle. This causes dropping of the toe during the swing phase of walking and "slapping down" of the foot after heel strike. Alleviation of these gait anomalies would improve mobility efficiency, safety, and cosmesis. Several types of orthotic devices fitted with springs and/or dampers have been used to control torque around the ankle and consequently facilitate the natural pattern of movement during the gait cycle. However, recent studies on powered upper-extremity orthoses controlled by EMGsignals from the users' impaired muscles have produced an unexpected and potentially exciting result. The use of EMG-controlled orthoses seems to improve the user's ability to control the compromised muscles and subsequently rebuild the connection between the brain and the output of those muscles. This could be a crucial step in helping stroke patients make a full recovery.; (cont.) Extending this control scheme to a powered ankle orthosis requires understanding the relationship between ankle torque and EMG signals measured on the muscles likely to serve as control signal sites. Studies have shown that the muscle whose deterioration is most responsible for drop foot gait is the tibialis anterior. Thus...
