title: SURGERY FOR LUMBAR DISC HERNIATION: OPEN X MINIMALLY INVASIVE TECHNIQUE

description: ABSTRACT Objective: In Brazil, there are no studies comparing endoscopic treatment of lumbar disc herniation with the conventional open technique in SUS (Unified Health System) with regard to hospitalization time and complications occurring within one year, which is the objective of this study. Methods: A survey of 32 surgeries performed in 2019 (11 open and 21 endoscopic) to evaluate pain parameters before and after surgery (VAS), days of hospitalization, and complications. The data were submitted to statistical analysis (ANOVA) using the Kruskal-Wallis test. Results: Fourteen patients were female and eighteen were male, with a mean age of 41.35 years (p&gt; 0.05 between sexes). The pre- and postoperative VAS for pain radiating to the lower limb were similar between the groups: 8.5 ± 0.82 with the open technique and 8.19 ± 1.15 with endoscopic technique. In both groups there was an improvement in the pain pattern with a significant reduction in the VAS (p &lt; 0.05) and there was no statistical relevance between the groups in terms of pain improvement. There was statistical relevance between the groups in the comparison of days of hospitalization required, with the group submitted to endoscopic surgery having a lower number of days. The complications reported were compatible with those found in the literature (postoperative dysesthesia, new herniation). Conclusions: The endoscopic technique resulted in an important reduction in the number of days of hospitalization, a factor with a high impact on the costs of any surgical procedure, which can be a determining factor in the feasibility of minimally invasive techniques.

title: The Identity Constitution of the Craft Beer Consumer in the City of Fortaleza (Brazil)

description: ABSTRACT With the transformation of the market into a provider of relevant symbolic resources, individuals like to demonstrate consumer goods that reflect their values and shared lifestyles. Thus, the aim of this study is to define identity profiles of craft beer enthusiasts based on their consumption practices. Using exploratory qualitative research, 55 consumers were interviewed and observations were made in the city of Fortaleza, Ceará, Brazil. The results present five consumer identity profiles in the culture of the craft beer consumer: Beginner, Adventurer, Beer Evangelist, Expert, and Beer Snob. The research enriches the studies inherent in consumer culture by presenting identity profiles based on consumption habits, and what is more, the research also makes a contribution by presenting the segmentation methodology in which the suggested identities can serve as a mechanism for industry organizations in the search for relationship strategies with the target audience.

title: Analysis of the Effects of Rivalry and Dynamism on the Firm’s Competitive Position

description: ABSTRACT The main objective of this study is to analyze the influences of dynamism and rivalry on the competitive position of US firms in the periods pre- and post-economic crisis of 2008, considering the role of firm size as a moderator. For this, data from firms operating in the manufacturing industry from 2001 to 2015 were used as a sample, analyzing the data through structural equation modeling. The model proposed in this study relates the constructs competitive position, dynamism and rivalry, using as a moderator the size of the firm. We found that the 2008 crisis influenced the environment in which the firms in the sample were inserted, causing a reduction in dynamism and rivalry. It was found that rivalry and firm size influenced competitive position, while dynamism, on the other hand, had little influence on competitive position. We also concluded that the dynamism of the industry has a direct influence on rivalry between firms.

title: THE MINIMALLY INVASIVE BIPOLAR TECHNIQUE FOR THE TREATMENT OF SPINAL DEFORMITIES IN CHILDREN AND ADOLESCENTS

description: ABSTRACT Scoliosis is a three-dimensional deformity of the spine that occurs during growth. Surgery is indicated when the curve progresses despite conservative treatment. The traditional surgical treatment involves correction of the deformity using segmental spinal fixation to obtain solid bone fusion by decortication and bone grafting. Vertebral osteotomies or even vertebrectomies may be required for huge deformities. These techniques provide good results, but they are invasive, involving lengthy surgery, increased blood loss, and longer recovery times. Therefore, we developed another technique: The Minimally Invasive Bipolar Technique, based on gradual internal correction of the deformity secondary to viscoelastic relaxation of the trunk. This method is aimed at reducing surgical risks while providing satisfactory results and improving quality of life for the patients and their families. Additionally, this technique is cost effective for public health. T ype of the study: Update article.

title: COMPARATIVE ANALYSIS OF CERVICAL SAGITTAL BALANCE WITH RADIOGRAPHS IN DIFFERENT POSTURES

description: ABSTRACT Objective: To compare the cervical sagittal balance in groups of patients submitted to lateral radiographs of the cervical segment, with the upper limbs in two different positions. Methods: This is a cross-sectional, quantitative, prospective, descriptive study using radiographic analysis of 100 adult individuals, aged between 20 and 70 years. Two lateral radiographs were taken of each patient, one image with the upper limbs crossed over the trunk (flexed elbows) and the other with the upper limbs elevated in front (extended elbows). All patients answered a questionnaire about age, sex, presence of pain in the cervical spine, as well as degree of pain based on the Likert scale. The radiographic parameters evaluated were the COBB angle (Cobb), thoracic inlet angle (TIA), T1 slope, neck tilt and distance from the center of gravity (COG) of the skull to C7 (COG-C7) with the elbows in extension (Ext) and flexion (Flex). A p-value of less than 0.05 was considered a statistically significant difference. Results: Sixty patients were female (60%) and forty were male (40%). The data analysis obtained showed statistical significance in Cobb Flex vs. Cobb Ext (p = 0.000), TIA Flex vs. TIA Ext (p = 0.000), T1 Flex vs. T1 Ext (p = 0.000), Neck tilt Flex vs. Neck tilt Ext (p = 0.000), and COG-C7 Flex vs. COG-C7 Ext (p = 0.000). Conclusion: There was statistical significance in relation to the positioning of the upper limbs in the lateral radiographs, yielding higher values in the angulations with the limbs raised towards the front (extended elbows).

title: Accounting Conservatism and National Culture

description: ABSTRACT The following study intends to evaluate the influence of Hofstede’s cultural dimension (2017) on a corporation from several countries’ accounting conservatism scale. Based on Thomson Reuters’ data and a final sample of 54,484 observations (32 countries), the analysis was made over a period from 2010 to 2016 and was based off on Ball and Shivakumar’s work (2005) in measuring accounting conservatism. When analyzing each cultural dimension individually, it was noted that companies from countries that have an individualistic culture would engage in bad accounting conservatism, while companies with a long term orientation exhibited the opposite attitude, according to the survey’s scenario. In general, the conclusion is that the national culture can impact accounting information quality, impacting on a larger or lesser extent for accounting conservatism. One of the main contributions of this study is the comprehension that the intrinsic cultural factors of each nation can influence the quality of the accounting information.

title: Sports Marketing and Perceived Value: an application of the conjoint analysis in the Fan Membership Programs of Football

description: ABSTRACT Football is ever present in Brazilians’ lives, and, more than a game, it also involves social and economic relations. Fan Membership Programs (FMPs), based on relationship marketing strategies, are ways to bring the clubs closer to their fans. This paper aims to analyze the perceived value structure of FMPs, based on sociodemographic profiles, starting with FMP attributes of the 2016 Brazilian Football Championship series A classified clubs. The data was collected online, and the population consisted of fans of the selected teams. The data was analyzed using the multivariate technique of Conjoint Analysis. It was verified that the general sample for different sociodemographic profiles, the ticket discounts, and prices of the FMP are the most valued attributes. This paper contributes to academy and practice by presenting a capable instrument to describe FMPs’ value perception. In academic terms, it contributes as a sports marketing management study. In addition, the paper could also apply as a tool for the Football clubs’ managers.

title: COMPARATIVE STUDY OF THE TYPES OF FIXATION IN ADOLESCENT IDIOPATHIC SCOLIOSIS

description: ABSTRACT Objective: To conduct a comparative study of the results obtained in the treatment of adolescent idiopathic scoliosis (AIS) with different types of fixations (traditional, selective and multiple), and to evaluate the correction of angular deformity in the frontal plane by the Cobb and sacral clavicular angle (SCA) methods. Methods: A study of a group of 278 patients with AIS who underwent selective, traditional, and multiple fixation surgeries. Results: Significant corrections of both the Cobb angle and the SCA were observed. Conclusions: In the multiple fixation surgeries there was a 100% correction between the preoperative and postoperative SCA values and a 50% correction in the traditional and selective fixations, a difference considered significant. Regarding the Cobb angle, the three fixations presented corrections between preop and postop with significant differences. Level of evidence III; Retrospective Study.

title: COST-EFFECTIVENESS OF VANCOMYCIN POWDER FOR DEEP WOUND INFECTION PROPHYLAXIS IN SPINE FUSION

description: ABSTRACT Objective: To identify the cost effectiveness of vancomycin powder in the prophylaxis of posterior lumbar spine instrumentation, seeking potential savings. Methods: A retrospective, observational study was performed to evaluate the cost effectiveness. Data were retrieved from patients’ files from March 2016 to April 2017; costs were considered for the procedures, as well as which antibiotic was used. Results: A total of 184 patients were included. Of these, 102 received prophylactic treatment with 1g of cephalothin and 82 received 1g of cephalothin and 1g of vancomycin powder, which was applied to the wound prior to tissue closure. Of the 184 patients, 110 were women (59%) and 74 were men (41%), and the mean age was 55 years (24-77). The participants had a median BMI of 28.9 kg/m2 (19-39). The average cost per hospitalized patient was $3974 USD and the average cost of rehospitalization due to infection was, on average, $7700 USD. The use of vancomycin powder led to cost savings of $75,008.79 USD per 100 posterior spinal fusions performed for degenerative spine. Conclusion: The use of vancomycin powder is a cost-effective option for prophylaxis of surgical site infection in spine fusion. Level of evidence III; Economic and decision analysis.

title: SPLIT-TYPE FRACTURES OF THE SPINE: A NEW MINIMALLY INVASIVE PERCUTANEOUS TECHNIQUE

description: ABSTRACT Objective: This research presents a biomechanical analysis performed in the lumbar spine of a porcine animal model, considering a minimally invasive technique for the treatment of split fractures. Methods: Porcine spines were used to perform compression tests, considering three different approaches. Three groups were defined in order to verify and validate the proposed technique: a control group (1); spines with split fractures (2); and a treatment group (3). For the first group (control), spines were axially compressed until any kind of fracture occurred, in order to verify the strength of the structure. In the second group, split fractures were created to obtain the mechanical failure pattern of the model. In the third group, the split fractures were submitted to the proposed treatment, to verify the resistance achieved. The three groups were compared by means of axial compression tests. Statistical analysis was performed by ANOVA. Results: The control group (intact spine) and the treated split fracture group presented similar results (p&gt;0.05), differing from the results for the untreated split fracture group (p&lt;0.05). Conclusions: The tests performed in order to determine the behavior and strength of the lumbar spine when subjected to axial compression provided positive data for the development of a minimally invasive technique capable of restoring split fractures of the spine.

title: IMPORTANCE OF RADIOGRAPHY IN ORTHOSTATISM IN THE CONDUCT OF THORACOLOMBAR TRANSITION FRACTURES

description: ABSTRACT Objective: To evaluate the importance of radiography in the orthostatic position in the initial assessment of patients with thoracolumbar transition fractures and whether this image changes the surgical indication. Methods: Medical records and imaging tests of patients treated for thoracolumbar transition fractures from June 2018 to June 2019 were evaluated. Trauma patients between 18 and 60 years of age with fractures of T10 to L3 who had been indicated for conservative treatment were included. Cases of fractures considered unstable were excluded. Radiographs were taken with the patient in the supine position (supine X-ray), computed tomography (CT), and orthostatic radiography (orthostatic X-ray). Segmental kyphosis and degree of wedging were evaluated. The measurements were compared using the Wilcoxon test. The McNemar test was used to assess changes in conduct according to the criteria for surgical indication (kyphosis ≥ 25 ° and wedging ≥ 50%). Results: Fifty patients were evaluated, nine of whom (18%) were indicated for a change of conduct according to the orthostatic examinations and were submitted to surgical treatment. Vertebral kyphosis increased by 40.6% (p &lt;0.001). The wedging increased by 25.62% (p &lt;0.0001). Conclusion: Eighteen percent of the total number of patients who did not present instability criteria in radiographs in the supine position satisfied at least one of these criteria when the orthostatic X-ray was performed.

title: INTEROBSERVER REPRODUCIBILITY ASSESSMENT OF THE NEW AOSPINE CLASSIFICATION FOR SUBAXIAL CERVICAL LESIONS

description: ABSTRACT Objective: To evaluate the interobserver agreement of the new AOSpine classification for subaxial cervical fractures. Methods: A descriptive study, which11 traumatic lesions of the subaxial cervical spine (through radiographic and tomographic images), were evaluated by 16 observers being: 6 senior surgeons, 4 fellows in spinal surgery and 6 physicians residents in Orthopedics and Traumatology by the new AOSpine classification, with subsequent statistical analysis of the results. An agreement analysis was performed using the Kappa coefficient, both individually and in combination, with an interpretation of the index performed using the standardized model for Landis and Koch. To determine the level of significance of the analyzes, values less than 0.05 were considered statistically significant. Results: In general, the level of agreement among the examiners was considered reasonable. The lesions “A0 (F3)”, “A4 (F3)”, “B1”, “B3”, “B3 (F3)”, “C”, “C (F3)” and “F3”showed a low level of agreement between the examiners. The level of reasonable agreement was obtained between fractures “A0”, “A1”, “A4”, “B2” and “C (F4)”. The only fracture that presented a moderate level of agreement was the “C (F4 BL)” lesion. This result indicates that the referred injury was the fracture of the subaxial column that presented the best level of agreement among the 16 examiners in the present study. Conclusions: The results of the study indicate an intermediate agreement of the new AOSpine classification for subaxial cervical lesion and point to the need to carry out studies that seek to evaluate this new classification in order to better evaluate its strengths and weaknesses, contributing for its improvement.

title: NONSPECIFIC SPONDYLODISCITIS IN ADULTS: RETROSPECTIVE STUDY

description: ABSTRACT Objective To describe the epidemiological and clinical characteristics of patients with pyogenic spondylodiscitis treated in a Brazilian hospital. Methods This is a retrospective study of patients diagnosed with nonspecific spondylodiscitis. Patients of both sexes, above 18 years of age with a minimum follow-up time of 6 months were included. Epidemiological, laboratory, and clinical data were analyzed. Results Nine patients were included. The mean age was 64 years, with seven men (77.7%) and two women (22.2%). All patients evaluated had back pain. The most affected location was the lumbar spine (44.4%). Only three patients (33.3%) had fever and five (55%) had constitutional symptoms. The mean duration of symptoms before diagnosis was 2.5 (± 1.5) weeks. Only four patients (44.4%) had positive cultures. As for neurological status, five patients (55.5%) presented neurological change. At the end of treatment, two patients improved one level in the Frankel score and two patients improved two levels. The main indication for surgery was neurological deficit (55.5%). Two of the patients evaluated died as a result of an infectious condition. Conclusions Less than half of the patients with pyogenic spondylodiscitis had fever or constitutional symptoms. Back pain was present in all cases. In less than half of the patients it was possible to isolate the responsible microorganism. Most patients underwent surgical treatment, although not all improved from the neurological deficit.

title: IMPACT OF THE GRADE OF DEGENERATIVE LUMBAR DISEASE ON THE OCCURRENCE OF SPINAL DEFORMITY

description: ABSTRACT Objective: To evaluate the impact of the severity of degenerative lumbar disease (DLD) on the occurrence of spinal deformity, as well as on the choice of treatment, whether conservative or surgical. Methods: This is a retrospective analysis of a prospective database. One hundred and thirty patients with low back pain and/or pain radiating to the lower limbs were included in the study and were graded on a DLD scale that considers total spine (panoramic) X-ray findings. The rates of adult spinal deformity (ASD) for the different degrees of the DLD scale were compared using the Chi-square test. The choice of treatment type, conservative or surgical, was also compared among the degrees of the DLD scale using Fisher's exact test. Results: The ASD rate was zero in grade 0 patients, 24% in grade I, 35% in grade II and 44% in grade III (P = 0.02). Grade III patients were more likely to be diagnosed with ASD (OR = 2.22; P &lt;0.05; 95% CI = 0.90-5.45) compared to the other DLD grades. Only 7.7% of the patients were chosen for surgical treatment and there was no difference by the DLD scale grade. Conclusion: There was correlation between the DLD grading scale and the occurrence of ASD, with at least twice the chance of this diagnosis in DLD scale grade III as compared to the other grades. The treatment of choice was conservative in a very small number of patients analyzed, with no difference between the different grades of the DLD grading scale. Level of Evidence III; Retrospective analysis of prospective database (cohort).

title: ADAPTATION AND TRANSCULTURAL VALIDATION OF THE BRAZILIAN VERSION OF THE BACK PAIN FUNCTIONAL SCALE

description: ABSTRACT Objective: The Back Pain Functional Scale (BPFS) was designed to evaluate the functional state of individuals with low back pain. The scale consists of twelve items, covering functional aspects of the daily life activities of these individuals. The final score is calculated by summing the responses to each item, the values of which range from 0 to 5, obtaining a total result of 0 to 60 points. Methods: The validation process was developed in accordance with the World Health Organization (WHO) protocol, covering translation, back translation, semantic equivalence, evaluation by specialists from previous stages, pre-test of the tool, and final version. Subsequently, the final version was applied in a sample of 90 individuals and the data obtained were subjected to descriptive statistical analysis, factorial analysis, evaluation of internal consistency, and correlation with other validated tools. Results: The tool was adapted to Brazilian Portuguese, making use of terms to approximate the language of everyday expressions. The final version presented results similar to those from the original version, as demonstrated by the factorial analysis, the internal consistency (Cronbach's alpha: 0.990), and the strong correlation with tools validated for the Portuguese language. Conclusion: The Brazilian version of BPFS proved to be easy to apply and understand, and presented high internal consistency and construct validity similar to that of the original instrument. Level of evidence 1B; Study of adaptation of a valid score.

title: CORRELATION BETWEEN CHRONIC LOW BACK PAIN AND FEMALE SEXUAL FUNCTION

description: ABSTRACT Objective To correlate chronic low back pain with female sexual function. Methods This is a cross-sectional study. Thirty-two women aged between 18 and 44 years old, with body mass index (BMI) between 18.5 kg/m2 and 29.9 kg/m2, with a medical diagnosis of chronic low back pain and sexually active in the last six months were selected. The patients underwent a physical therapy evaluation and responded to two questionnaires: the Roland-Morris Disability Questionnaire and the Female Sexual Quotient (QS-F). Pearson’s correlation test was used to assess the impact of chronic low back pain on sexual activity. Results The mean age was 30.31 years old (±.7.10) and the mean BMI was 24.54 Kg/m2 (±3.06). The mean Roland-Morris Disability Questionnaire score was 5.2 ( ± 3.28), indicating that the patients did not have significant disability. The mean QS-F score was 60.37 (±14.48), classified as “unfavorable to normal”. The correlation test showed a low correlation between chronic low back pain and female sexual function (r = 0.027). Conclusion There was a low correlation between chronic low back pain and female sexual function in the study population, but the moderate correlation between the “comfort” domain and the Roland-Morris Disability Questionnaire score was significant. Level of evidence II ; Cross-sectional clinical study.
