Published: November 2018

ABSTRACT Objective: To verify if there is consensus about the treatment of each type of injury or amputation of the fingertips, and if there is a statistical difference among the treatment options according to the surgeon's length of time in the hand surgery specialty. Methods: A cross-sectional survey was conducted during the 37th Brazilian Congress of Hand Surgery, when one hundred and twenty questionnaires were randomly distributed. Observing the inclusion and exclusion criteria, ninety completed questionnaires were included. The answers were submitted to descriptive and inferential analysis with a significance level of p <0.05. Results: This study showed agreement of 63.3% for the treatment with statistical difference for dorsal oblique injury less than 1 cm with bone exposure for the VY advancement flap alternative; 46.7% for volar tip oblique injury with bone exposure less than 1 cm for the Cross Finger alternative; 47.8% for oblique thumb volar injury greater than 1 cm with no bone exposure to the Moberg alternative; 54.4% for thumb pulp injury up to 2.5 cm with bone exposure to the Moberg alternative with proximal release, and 92.2% for antibiotic use, for the “cephalexin” alternative. Conclusion: There is no consensus regarding the treatment of most types of fingertip lesions, with agreement of 45.4%. When we subdivided by time group of specialty in hand surgery, there was an increase in agreement to 54.5% of the questions per subgroup. Further comparative studies are needed to assess the consensus among surgeons regarding the treatment of fingertip injury. Level of Evidence III; Cross-sectional survey.

Published: November 2018

ABSTRACT Objective: There are no specific criteria that define the level of amputation in diabetic patients. The objective of this study was to assess the influence of clinical and laboratory parameters in determining the level of amputation and the wound healing time. Methods: One hundred and thirty-nine diabetic patients were retrospectively assessed. They underwent surgical procedures due to infection and/or ischemic necrosis. Type of surgery, antibiotic use, laboratory parameters and length of hospital stay were evaluated in this study. Results: The most common amputation level was transmetatarsal, occurring in 26 patients (28.9%). The wound healing time increased with statistical significance in individuals undergoing debridement, who did not receive preoperative antibiotics and did not undergo vascular intervention. Higher levels of amputation were statistically related to limb ischemia, previous amputation and non-use of preoperative antibiotics. Conclusion: Patients with minor amputations undergo stump revision surgery more often, but the act of always targeting the most distal stump possible decreases energy expenditure while walking, allowing patients to achieve better quality of life. Risk factors for major amputations were ischemia and previous amputations. A protective factor was preoperative antibiotic therapy. Level of Evidence III, Retrospective Study.
SPORTS ACTIVITY AND HIP, KNEE, SHOULDER AND INTERVERTEBRAL DISC ARTHROPLASTIES
Authors: Moura Diogo Lino , Fonseca Fernando Pereira
Published: November 2018

ABSTRACT The success of joint replacement surgery has been responsible for raising patients' expectations regarding the procedure. Many of these procedures are currently designed not only to relive the pain caused by arthrosis, but also to enable patients to achieve functional recovery and to engage in some degree of physical activity and sports. However, as physical exercise causes an increase in forces exercised through the articular prosthesis, it can be an important risk factor for its early failure. Scientific literature on sports after arthroplasty is limited to small-scale retrospective studies with short-term follow-up, which are mostly insufficient to evaluate articular prosthesis durability. This article presents a review of the literature on sports in the context of hip, knee, shoulder and intervertebral disc arthroplasty, and puts forward general recommendations based on the current scientific evidence.

Published: November 2018

ABSTRACT Objective: To assess the intra- and inter-observer reliability of a Brazilian Portuguese translated and cross-culturally adapted version of the mJOA questionnaire. Methods: The reliability of the Brazilian Portuguese version of the mJOA scale was assessed through the evaluation of a sample of patients with cervical myelopathy by two independent experienced spine surgeon examiners. Inter-observer reliability was defined by the Intraclass Correlation Coefficient (ICC) between the evaluations of the two examiners, and intra-observer reliability was assessed by the ICC between the two evaluations of one examiner. Results: Fifty-five patients were included in the study (mean age 58.7 years). The ICC for inter-observer reliability of the Brazilian Portuguese version of the mJOA was 0.967, and the ICC for intra-observer reliability was 0.869, both classified as “almost perfect” (> 0.81). Conclusion: The Brazilian Portuguese translated and cross-culturally adapted version of the mJOA questionnaire appears to be valid and reliable.

ABSTRACT Objective: Nerve transfers are an alternative in the reconstruction of traumatic brachial plexus injuries. In this study, we report the results of branchial plexus reconstruction using accessory to suprascapular nerve transfer. Methods: Thirty-three patients with traumatic brachial plexus injuries underwent surgical reconstruction with accessory to suprascapular nerve transfers. The patients were divided into groups in which surgery was performed either within 6 months after the injury or more than 6 months after the injury. Results were assessed using the Constant score. Results: There was no significant difference between the groups with respect to the Constant score. Conclusion: Accessory to suprascapular nerve transfer was not an efficient method for recovering active ROM or strength in the shoulder. However, it effectively improved pain control and shoulder stability. Level of evidence II, Retrospective Study.

ABSTRACT Purpose: The purpose is to compare the incidence and characteristics of injuries sustained in two consecutive seasons of the São Paulo State Football Championship. Methods: Prospective study performed using an electronic form previously developed by the Medical Committee of the São Paulo State Football Federation, sent to the physicians responsible for the tournament's series A1 and A2 teams, after each round. Results: 17.63 injuries sustained per 1000 hours of matches in the A1 series and 14.91 injuries sustained per 1000 hours of matches in the A2 series. Incidence of injuries per 1000 hours of matches decreased from 24.16 to 17.63 in the A1 series (p<0.037) and from 19.10 to 14.01 in the A2 series (p<0.064). External defenders suffered most injuries, while muscular injuries were most common and lower limbs, the most affected areas. Most injuries occurred between 30 and 45 minutes of the match and only 11.9% of the injuries required surgery. Conclusions: Prevalence and frequency of injuries decreased between seasons. Most injuries were sustained in the lower limbs; strains were the most common injuries, followed by strains and contusions; MRIs were the most frequently requested exams and most injuries were classified as moderate (8-28 days).

Published: November 2018

ABSTRACT Objective: To compare the widening of bone tunnels between poly-etheretherketone (PEEK), absorbable polylactic acid DL (PLDL) and tricalcium phosphate (TCP) interference screws in anterior cruciate ligament (ACL) reconstruction. Methods: Three groups of patients undergoing ACL reconstruction with at least 1 year of follow-up using the out-in drilling technique and hamstring as a graft were assessed. The patients were divided according to the type of interference screw used (PEEK, PLDL and TCP). Computed tomography (CT) was performed to measure the greatest femoral and tibial tunnel widening regarding to the initial tunnel, and then it was compared between groups. Results: Mean widening in group 1 (PEEK) was 39.56% (SD 16%) in the femoral tunnel and 33.65% (SD 20%) in the tibia. In group 2 (PLDL) mean widening was 48.43% in the femoral tunnel (SD 18%) and 35.24% (SD 13%) in the tibial tunnel. In group 3 (TCP) mean widening was 44.51% in the femur (SD 14%) and 36.83% in the tibia (SD 14%). The comparison between groups (PLDL-PEEK, PLDL-TCP, PEEK-TCP) shows no statistically significant difference. Conclusion: Bone tunnel enlargement values after ACL reconstruction with the use of different types of materials (bioinert and biomaterials) of interference screws (PEEK, PLDL and TCP) were similar.

Published: November 2018

ABSTRACT Objective: To introduce the intralesional calcitonin and methylprednisolone percutaneous injection method, which results in the promotion of primary aneurysmal bone cyst (ABC) healing. Methods: A retrospective cohort study involving 76 patients diagnosed with ABC was performed between 2005 and 2014. Patients treated with calcitonin and methylprednisolone injection and who underwent more than 2 years of follow-up were considered eligible for the study (n=47). The Enneking staging and Capanna classification systems were used during the initial evaluation. Treatment response was assessed by Rastogi radiographic grading based on the degree of healing. X2 and Wilcoxon signed-rank tests and odds ratio calculations were used in the statistical analysis with a 5% significance level. Results: The proximal tibia extremity was the most commonly affected site (17.0%). Thirty-three (70.3%) ABC cases were staged as B3 and 28 (59.7%) were classified as type II. The average number of injections performed was 2.8 per patient, with an average reduction of the initial lytic area of 83.7% (p-value=0.00001). Satisfactory results for 91.4% (n=43; p-value=0.00001) were obtained and 5 recurrences occurred. No side effects were observed. Conclusion: Intralesional calcitonin and methylprednisolone percutaneous injection is a minimally invasive, effective, and safe method for promoting primary ABC healing. Level of evidence IV, Type of study: case series.

Published: November 2018

ABSTRACT Objective: Myxofibrosarcoma (MFS) is a common soft tissue sarcoma (STS) that affects the extremities in elderly patients. The objective was to analyze the prognostic factors and outcomes of patients with MFS treated at a single institution. Methods: We retrospectively reviewed the records of 75 patients with MFS. We compared age, sex, tumor size and location, grade and stage of the disease. Median age was 49.7 years (range, 1 to 88 y). Location: upper extremity (25.4%), lower extremity (66.6%) and pelvis (8%). Patients had high-grade tumors in 46.7% of the reports. Margins were negative in 76% of the cases. Bivariate Cox regression analysis was used to determine associations between clinical and treatment factors with local recurrence (LR). Results: Median follow-up time was 30.7 months (range, 1.8 to 383.8 m). We found 26.7% of LR. Distant metastasis (DM) was reported in 27 (36%) patients. Lung was the most common site of DM, reported in 92.6% of patients. Overall survival (OS) with metastasis was 21.2 months (range, 4.8 to 114.8 m). Predictors of OS were grade, LR (hazard ratio [HR] 5.13, 95% confidence interval, 2.15-12.24, P <0.001), and DM (HR 540.97, 95% confidence interval, 5.04-58112.03, P< 0.001). Conclusions: Tumor grade, LR, positive margins and DM were significant predictors of poor OS prognosis. Level of Evidence IV, Case Series.

Published: November 2018

ABSTRACT Objective: The cause of anterior shoulder instability is not fully understood and surgical management remains controversial. The objective of this study was to evaluate the results of patients undergoing arthroscopic Latarjet procedure with endobuttons. Methods: A retrospective study of 26 patients undergoing arthroscopic Latarjet procedure with endobuttons to treat anterior shoulder instability. Patients with previous glenohumeral instability, failure of Bankart procedure or Instability Severity Index Score (ISIS) greater than or equal to 6, were included. Patients were assessed by: DASH, UCLA, Rowe, Visual Analog Scale (VAS) of pain and Short-Form 36 (SF36) scores. Correct position and consolidation of the graft were evaluated. Results: Mean age was 31.5 years (16 to 46). Preoperative duration of symptoms was 1.7 years (1 month to 10 years). Mean follow-up was 14.3 (6 to 24) months. Mean postoperative scores were: 10 points in DASH; 1.6 in VAS, where 23 (88%) patients experienced mild pain and 3 (12%) moderate pain; 89 in Rowe; 32 in UCLA and 78 in SF-36. Positioning of the graft was correct in 25 (96%) cases, and was consolidated in 23 (88%). We had two cases of graft fracture (7%) and postoperative migration (7%). Conclusion: Surgical treatment using arthroscopic Latarjet with endobuttons is safe and effective, producing good functional outcomes in patients. Level of Evidence IV, Case Series.
Insect galls on Myrtaceae: richness and distribution in brazilian restingas
Authors: Maia Valéria Cid
Published: November 2018

Abstract: Inventories in Brazilian restingas have been indicating that Myrtaceae are the plant family with the greatest richness of insect galls. A compilation of published data plus new records was elaborated with the aim of stablishing the number of gall morphotypes on this family in this physiognomy of the Atlantic Forest, producing a list of galled species, pointing out the predominant gall features, evaluating the taxonomical knowledge of the gallers, listing the associated fauna, and based on host plant endemisms and monophagy proposing the endemism of some galling species. Myrtaceae harbor 111 morphotypes of insect gall (about 75% induced by Cecidomyiidae, Diptera) on 25 host plant species, 15 endemic. Eugenia L. highlights as the plant genus with the highest number of galled species and gall richness. Leaves are the most galled organ. There is a predominance of globoid and fusiform shapes, green color, glabrous surface and a single internal chamber. The taxonomical data on gallers is deficient as many records have been presented at supraspecific levels. The associated fauna is rich and includes parasitoids, inquilines and predators. Twelve species of Cecidomyiidae, a single species of Curculionidae (Coleoptera) and one species of Eriococcidae (Hemiptera) have been associated exclusively with endemic hosts and then are proposed in the present study as endemic too. The geographical distribution of many galls and respective gallers are restricted to the State of Rio de Janeiro, where most inventories have been carried out. For the first time, Eugeniamyia dispar, previously known from a rural area of Rio Grande do Sul and restinga areas of São Paulo, is recorded in the State of Rio de Janeiro.

ABSTRACT: The present study aimed to establish a methodology capable to cause intestinal ischemia and reperfusion injuries, to perform clamping of the jejunal segment of the extramural peri-intestinal marginal artery branch. For this, 37, 10-week-old male New Zealand breed rabbits were used. One rabbit was used to establish the anatomic references for the procedure and was not part of the six experimental groups; the rest were allocated into six experimental groups: Sham group, negative control, subjected only to midline celiotomy; group I1H undergoing vascular occlusion for an hour; group I2H submitted to vascular occlusion for two hours; group I1H/R2H undergoing vascular occlusion for one hour followed by two hours of reperfusion; group I2H/R1H undergoing vascular occlusion for two hours, followed by reperfusion for one hour, and group I2H/R5H undergoing vascular occlusion for two hours followed by reperfusion for five hours. The rabbits were evaluated for the macroscopic aspects (color and peristalsis) of the jejunal segment, as well as the histological aspect, checking for presence or absence of mucosal destruction, edema, hemorrhaging, lymphatic vessel dilatation, and the presence of polymorphonuclear cells. It was observed that the macroscopic and histopathological lesions accentuated in larger employed ischemia and reperfusion times. Rabbits subjected to ischemia for two hours followed by reperfusion for five hours (I2H/R5H) made up the experimental group which was easily reproducible and showed moderate intestinal injury, different from the other groups.

Foram utilizados 654 animais, sendo 334 animais no período seco, dos quais eram 149 matrizes e 185 crias e 320 animais no período chuvoso, sendo 106 matrizes e 214 crias, independente de padrão racial e sistema de criação. As coletas foram realizadas nos meses de novembro e dezembro de 2012 e maio de 2013 no município de Quixadá-Ceará e encaminhadas ao Laboratório de Parasitologia da Embrapa Caprinos e Ovinos na cidade de Sobral-Ceará. Foram coletadas fezes para contagem do número de ovos por gramas de fezes (OPG), contagem de Oocistos por gramas de fezes (OOPG), coprocultura e identificação das espécies de Eimeria com base na morfometria. As matrizes apresentaram maiores médias de ovos do tipo Strongyloidea (372,03) e Strongyloides (8,45) no período seco e no período chuvoso apresentaram maiores médias apenas para Strongyloidea (502,85). O inverso aconteceu com o OOPG, onde as crias apresentaram maiores médias no período seco (9387,41) e no chuvoso (9630,37). O gênero de nematódeo mais frequente na coprocultura foi o Trichostrongylus sp. (63,67%) no período seco e o Haemonchus sp. no chuvoso (66,67%). Em 100% dos rebanhos, foram encontrados oocistos de Eimeria, com 81% dos animais infectados. A ocorrência da eimeriose nas categorias jovens e adultas foi de 64,3% e 83,2% no período seco e de 87,4% e 92,4% no período chuvoso. As espécies identificadas foram: Eimeria alijevi, E. apsheronica, E. arloingi, E. caprina, E. caprovina, E. christenseni, E. hirci, E. jolchijevi e E. ninakohlyakimovae. Nas crias a E. alijevi foi a mais freqüente no período seco e a E. ninakohlyakimovae no chuvoso. Já nas matrizes a espécie E. alijevi apresentou a maior frequência em ambos os períodos. Nos rebanhos estudados foi evidenciado a presença de ovos de nematódeos gastrointestinais e oocistos de Eimeria spp. independente da categoria animal.

ABSTRACT: In humans, left atrial enlargement and reduced contractile functions are associated with adverse cardiovascular events and a poor prognosis in many dilatation of the left atrium occurs with the gradual evolution of chronic mitral valve disease and is well diseases. The left atrium is the most compromised cardiac chamber in dogs with chronic mitral valve disease (CMVD). Therefore, this study aimed to compare the main parameters of left atrial enlargement (left atrium/aorta ratio, left atrial diameter and volume indices) and contractile function (transmitral flow peak velocity A wave and time velocity integral, atrial fraction, and atrial ejection force) at different stages of valve disease, and correlate the left atrial diameter, volume, and contractile function indices with echocardiographic variables predictive of heart failure in dogs (transmitral flow peak velocity E wave, E wave/IVRT ratio, E wave/E´wave ratio, and E wave/A wave ratio). The results showed that progressive characterized by the left atrium/aorta ratio and left atrium volume index. The left atrial diameter and volume indices and left atrium/aorta ratio correlated positively with the transmitral flow peak velocity E wave and E wave/IVRT ratio, which are important indices of diastolic function. The left atrial contractile function indices increased as CMVD evolved. Except for the atrial fraction, the left atrial contractile function indices correlated with the left ventricular filling pressure indices.

RESUMO: Este estudo retrospectivo incluiu cães paraplégicos com ausência de percepção a dor profunda secundário a doença do disco intervertebral toracolombar e submetidos à cirurgia descompressiva. Teve como objetivo comparar a recuperação funcional e a qualidade de vida (QV) quando submetidos a um protocolo em um centro especializado ou a domicílio realizado pelo tutor. Vinte e oito cães foram distribuídos no grupo A (GA) e submetidos ao protocolo domiciliar e 38 denominados grupo B (GB) em um centro especializado. Recuperaram a habilidade de caminhar 43% dos cães em uma média de 40 dias de pós-operatório (PO) no GA e 42% em uma média de 36 dias no GB. Em 53% dos casos (35/66) os cães permaneceram paraplégicos sem percepção a dor profunda ao final do período de 90 dias de PO. Vinte e cinco tutores do GA e 26 do GB responderam um questionário sobre a QV, com no mínimo seis meses de PO. A avaliação do tempo de sobrevida dos animais, realização de eutanásia e nota atribuída a QV demonstraram que os cães do GB provavelmente foram beneficiados pelo estreito acompanhamento e orientação aos tutores até 90 dias PO.

ABSTRACT: In a paddock highly invaded by Senna obtusifolia 10 out of 60 sheep showed muscle weakness and 9 died after a clinical manifestation period of 24-76 hours. Serum activities of creatine kinase were increased in all sheep examined. Multifocal polyphasic muscle segmental degeneration and necrosis was observed in skeletal muscles. Although the plant is a common weed in northeastern Brazil, the poisoning is rare, probably because the animals do not ingest it or due to toxicity variations.

Impact of the Brazilian Accounting Pronouncements Committee’s New Guideline (OCPC 07) on the downsizing of companies’ Notes
Authors: Santos Edilene Santana , Calixto Laura , Bispo Maira Ferreira
Published: November 2018

ABSTRACT This article aims to assess the impact of the New Guideline of the Brazilian Accounting Pronouncements Committee (Comitê de Pronunciamentos Contábeis - OCPC 07) on improving formal features (size, readability, and specificity) of Brazilian companies’ Notes. OCPC 07 is one of the world’s first guidelines issued in response to the current demand for the downsizing of companies’ Notes, which according to standard setters and market agents have become too extensive, thus characterizing a disclosure overload. This is a unique study on the subject. The results suggest the effectiveness, although limited, of the new standard in promoting a departure from the habits of secrecy and formalism rooted in centuries of legal-accounting civil law tradition, and indicate that there is still room for complementary improvement initiatives in the form of incentives for firms and increased enforcement. Three complementary methodological approaches are used: (1) an analysis of both the evolution of note size after OCPC 07 and the factors explaining that size and its variation; (2) an examination of indicators of readability, conciseness, and specificity of the note on accounting policies; and (3) a size comparison of the Notes of Brazilian and British companies, a benchmark of the common law tradition. An average reduction of 10% in Note size was found two years after the introduction of Guideline (Orientação) 07 by the (OCPC 07). This downsizing was not generalized, but instead identified only among firms in the Novo Mercado and among those audited by two of the Big Four. Even in firms that reduced their notes by at least 20%, no significant improvements in readability levels could be perceived, nor in habits of copy-pasting the auditors’ templates, which could signal a focus on firms’ real practices in the note on accounting policies. Brazilian Notes remain far from the benchmark and are still 40% longer than British ones, despite an equivalent number of pages being expected.
Weeds associated with cotton crop and hosting whitefly
Authors: Rodrigues Sandra , Silva Alexandre Ferreira
Published: November 2018

ABSTRACT: The whitefly can be hosted by weeds and cause damage to cotton crops. The objective of this work was to identify which species of weeds among the floristic compositions occurring in the cotton crop are hosts of whiteflies (Bemisia tabaci biotype B). Bi-weekly evaluations were performed in a cotton area (FM 975 WS) in Sinop, Mato Grosso, Brazil, during the reproductive phase of the crop. An inventory square (0.25 m side) was randomly cast 15 times between the cotton rows. The weeds were cut close to the ground, conditioned and taken to the laboratory to identify the family and species, and to quantify the eggs and nymphs of whiteflies. Eleven families were detected, with the most frequent being Amaranthaceae (16.67%), Convolvulaceae (12.5%), Rubiaceae (12.5%) and Poaceae (12.5%). The most frequent species were Amaranthus spp. (13.79%) and Alternanthera tenella, Ipomea spp., Richardia brasiliensis and Eleusine indica, with 10.34% each. From the 15 collected species, the presence of whitefly eggs or nymphs was only not observed in Portulaca oleracea and E. indica. The highest incidence of B. tabaci occurred in Euphorbia heterophylla. The occurrence of these species should be monitored, so that the whitefly population does not interfere in the cotton fiber quality.

Published: November 2018

ABSTRACT: Petri disease is complex, attacks young vine plants and it is difficult to be controlled. The fungus Phaeomoniella chlamydospora (Phc) has been identified as the main causative agent of this disease. This study aimed to evaluate the prevalent colonization of the Petri disease fungi in different portions of vine plants; to assess the susceptibility of grapevine rootstocks to the fungus P. chlamydospora; to assess the effect of solarization and biofumigation, followed by hot-water treatment (HWT), on the disinfection of cuttings of the rootstock IAC 766 infected with P. chlamydospora, and assess the effect of solarization and biofumigation, followed by HWT, on the rooting of cuttings of the rootstock IAC 766. For the prevalent colonization test, the fungus species detected and identified in ‘Niagara Rosada’ grafted on two rootstocks different were Phc and Phialemoniopsis ocularis. This is the first report of P. ocularis in a young vineyard in Brazil. Both fungi, in particular Phc, colonized only the plant’s basal part, drawing attention to the rootstock as target for control measures. Measurement of the dark streaks in the vascular system revealed that Golia was the least susceptible rootstock, and IAC 572 was the most susceptible to Phc. Moreover, biofumigation or temperature of 37°C applied for 7 and 14 days, both followed by HWT, suppressed Phc in cuttings of the rootstock IAC 766 without hampering their rooting. Meanwhile, new studies are needed to validate the efficiency of these disinfection techniques.

Conclusão: constatamos que encarar a formação como meio de desenvolvimento de recursos para a ação a torna um processo mais potente, tanto em sua eficácia quanto em seu potencial em produzir saúde. Para isso, afirmamos a imprescindibilidade de viver os conflitos da atividade de trabalho para o qual se quer formar, conjugada com espaços coletivos de discussão das experiências vividas nos dispositivos de formação.

Resumo Este ensaio apresenta as oficinas emancipatórias como proposta de intervenção em saúde do(a) trabalhador(a), voltada para trabalhadores(as) da saúde. As oficinas têm como referencial teórico-metodológico o Materialismo Histórico e Dialético. Estão ancoradas particularmente no conceito de trabalho como categoria central de análise das relações sociais e nas teorias da determinação social do processo de saúde e da educação emancipatória. A oficina emancipatória é estratégica para promover a análise crítica dos processos de trabalho e a proposição da superação de práticas reiterativas que caracterizam o processo de produção em saúde. Coerentemente ao referencial teórico, a oficina consiste em processo educativo que se vale de estratégias dialógicas, que permitem a exposição clara da essência para a formulação de novas sínteses dos fenômenos em discussão. Novos conhecimentos e práticas só podem ser alcançados pela crítica radical ao processo de produção em saúde e ao capitalismo em última instância.

ABSTRACT Managed Aquifer Recharge (MAR) is a useful tool for the treatment and use of sewage effluent because it complements conventional treatment, recovers the aquifer and minimizes risk of saltwater intrusion. This study aims to investigate technical data to determine the treatment of wastewater stabilization pond effluent using undisturbed soil columns collected from a coastal watershed study area within the BRAMAR (BRAzil Managed Aquifer Recharge) project. The treatment efficiency was monitored by measuring physico-chemical parameters (BOD 5, COD, DOC, TSS, NH3 and NO3) in two columns filled with undisturbed sandy soil in which sewage effluent was infiltrated under unsaturated condition for 72 days with an average input flow of 10 mm h-1. Results indicated reduction greater than 60% of organic matter, suspended solids and ammoniacal nitrogen. However, high concentrations of nitrate in the outflow were detected originating from nitrification of ammoniacal nitrogen. Moreover, difficulties in relation to soil clogging were observed. Furthermore, this study brought relevant contributions to understanding the influence of the infiltration rate and ability to treat effluent from wastewater stabilization ponds using undisturbed soil columns. Future research should be undertaken to improve the pretreatment methods and the operation of a MAR system in the study area.
INTEGRATION BETWEEN RESEARCH AND DEVELOPMENT: A DYNAMIC CAPABILITIES PERSPECTIVE

Published: November 2018

ABSTRACT Integration between research (R) and development (D) activities when they are organized separately in companies as specific departments is crucial for innovation performance and for the firm's adaptation and growth. Although this is of utmost importance, paradoxically, very few studies have focused on it. Considering this integration as a dynamic capability, through a systematic literature review on integration models and dynamic capabilities, we discuss distinctive views of the concept and the ways in which they can be applied. This study leads to the systematization of this knowledge field and to the identification of gaps in the literature on the integration between R and D. A research agenda is also proposed.

Published: November 2018

RESUMO O papel da indústria manufatureira nas cadeias de valor tem se tornado menos expressivo diante da tendência de estagnação da demanda, comoditização dos produtos e diminuição da lucratividade. Diante desse cenário desafiador, um número crescente de empresas busca adicionar valor a seus negócios pela vertente da "servitização" (oferta de soluções produto-serviço). Contudo, a literatura dessa temática encontra-se dividida quanto à efetividade dessa abordagem, dado que, nem sempre, traz o impacto esperado no desempenho organizacional (paradoxo do serviço). Diante disso, o trabalho avaliou quantitativamente essa relação em empresas industriais do setor de Máquinas e Equipamentos. Dados sobre as diferentes categorias de serviços por elas desenvolvidas e seus impactos foram coletados. Verificou-se que há uma relação positiva e relevante entre a oferta da maioria dessas categorias e o desempenho organizacional, o que indica que, identificando e desenvolvendo uma composição de serviços consistente, é possível conduzir uma efetiva estratégia de servitização.
Briefing: Measuring pavement skid resistance – comparing manually pushed and trailer-mounted devices
Authors: Stokes James , Nassar Ahmed I. , Wright Michael
Published: November 2018

In 2009, a manually pushed device was developed to measure the dry and wet skid resistance of pavement surfaces at walking pace. The device is based on the same principle as a larger trailer-mounted version and provides a continuous measurement of skid resistance; it is particularly suitable on sites where the survey speed cannot be achieved by trailer- or vehicle-mounted devices. The manually pushed device is also useful for restricted test sections and where the incline, camber or gradient are not desirable for other survey methods. However, the device is not currently covered by a national or international test standard. Its use has also been restricted due to a lack of published research regarding the correlation of results with other methods of measurement. This paper describes on-site testing conducted using the manually pushed device to assess the correlation of the test results with results provided by a trailer-mounted device. The repeatability of the test method and the influence of survey speed on the test results are also examined.

Moving towards Universal Coverage of Direct-Acting Antiviral Therapies for Hepatitis C Infection in Canada: An Environmental Scan of Canadian Provinces and International Jurisdictions
Authors: Myers Samantha , Khosa Gurleen , Kuo I fan , Janzen Donica , Alessi-Severini Silvia
Published: November 2018

Background: Direct-acting antivirals (DAAs) have become the standard treatment for patients with chronic hepatitis C infections because of their high cure rates and favourable side effect profiles; however, access to this new class of agents has been limited because of its high cost.  Public payers across Canada have implemented strict criteria for drug coverage in order to contain expenditures. Efforts have been made to improve access to medication for this high-burden condition. Recent coverage criteria across national and international jurisdictions have been compared.Methods: Coverage criteria for several DAAs were reviewed by accessing Canadian provincial drug formularies. International coverage (e.g., Europe, Australia, United States, Egypt, India) was reviewed by searching available literature. Results: Coverage criteria vary across Canada. By April 2018, most Canadian jurisdictions had removed the stage 2 liver fibrosis requirement for patients to be eligible for coverage. Internationally, patients’ access to DAAs differs significantly. Many jurisdictions restrict DAA prescribing authority to specialists and request documentation of chronic hepatitis C. In the US, considerable gaps of coverage are identifiable and patients might face significant financial burden to receive treatment. Conclusion: DAAs appear to be generally accessible through public drug plans in Canada compared to other countries.
Bruxismo una enfermedad de altura
Authors: Varela Orduz Juan Fernando , Marulanda Corredor Rocío del Pilar
Published: November 2018

El bruxismo es una parafunción oral caracterizada por el apretamiento y/o rechinamiento de los dientes durante el sueño o vigilia. Se le considera un factor etiológico de las altera- ciones funcionales y dolorosas de la unidad cráneo-cérvico-mandibular, así como de la destrucción progresiva de la estructura dental y periodontal.
El apretamiento dental o bruxomanía es uno de los más prevalentes, complejos y destructivos desordenes orofaciales, puesto que solo un bajo porcentaje de los pacientes son conscientes de que están apretando los dientes, generalmente lo que llama la atención son sus efectos destructivos e irreversibles que posteriormente son complejos y costosos de rehabilitar. El estrés laboral se asocia a menudo como un factor que contribuye al bruxismo, y la profesión de piloto militar supone un manejo de estrés de alta complejidad, por lo anterior, el objetivo de este estudio fue determinar la prevalencia de bruxismo en pilotos de la Fuerza Aérea Colombiana.
Se realizó un estudio descriptivo en el Centro de Medicina Aeroespacial de la Fuerza Aérea Colombiana, en el cual se calculó la incidencia de bruxismo en 284 pilotos militares que asistieron a sus exámenes médicos de control anual de aptitud psicofísica, entre el 1 de octubre de 2012 y el 30 de junio de 2013. Esto debido a que no se cuenta con datos estadísticos en Colombia acerca del porcentaje de pilotos que presentan esta patología.
Como resultado se evidenció, que la prevalencia de bruxismo en pilotos fue del 41.24 %. El 42.47 % reportó niveles altos de estrés en su profesión como piloto militar, y el 50.44 % reportó niveles de estrés medio. El 61.76 % de los pilotos de grado de Teniente Coronel dieron positivo para bruxismo. No se encontró diferencia significativa de acuerdo al tipo de aeronave que vuelan, ya sea ala rotatoria o ala fija helicóptero o avión. El 20.35 % de los pilotos tienen alguna sintomatología dolorosa relacionada con el bruxismo y el 38.05 % reportaron ser conscientes de que aprietan los dientes durante el sueño, un 13.27 % reportó que durante su rutina de vuelo aprietan los dientes. El 27.43 % están recibiendo algún tratamiento para el bruxismo.
En conclusión, los resultados demostraron una prevalencia de bruxismo en el personal de pilotos de la Fuerza Aérea Colombiana del 41.24 %, solo el 27.43 % de los pilotos que fueron diagnosticados como bruxomanos reciben algún tratamiento para esta patología, y el 38.05 % de los pilotos son conscientes de que están apretando los dientes, lo cual obliga a la realización de programas de promoción, prevención y establecimiento de protocolos de atención para el manejo de esta patología.
