title: Business engineering incubators: a cooperation case for cluster’s development

description: Abstract Paper aims To present the performance and contributions of a business incubator that acts as a link between the members of an industrial cluster and a higher education institution that acts in the field of engineering. Originality Most articles focus on incubators from the point of view of internal activities, the nature of incubation processes, and financing intermediary programs for nascent businesses. This work aimed to broaden the traditional approach of the academic constructs researched on the role of business incubators by bringing the contributions of one of the largest Brazilian business incubators to the formation and development of an industrial cluster. Research method The results represent the extract from a case study. The inductive method of basic research with a combined approach is applied for exploratory and descriptive purposes, using documentary analysis and field research. Main findings This paper addresses a successful integration between an engineering school and the business environment through its incubator while summarizes the trajectory of this incubator, and highlights, among other contributions to the local industrial cluster, the significant survival rate of its graduated companies. Implications for theory and practice Coordinated actions among members of the triple helix model are evidenced in this paper and may form the basis for similar experiments involving government agencies, educational institutions and the industrial environment.

title: Turkish validity and reliability of Eustachian tube dysfunction questionnaire-7

description: Abstract Introduction During clinical evaluations, in order to interpret patients' complaints caused by Eustachian tube dysfunction and to monitor the success of the treatment, standardized and disease-related scales are necessary. Objective The aim of this study was to investigate the validity and reliability of the Turkish version of Eustachian tube dysfunction questionnaire-7. Methods Forty patients diagnosed with Eustachian tube dysfunction and 40 healthy individuals were enrolled for the study. After language validation of the Eustachian tube dysfunction questionnaire-7 for Turkish, a scale was completed by the both Eustachian tube dysfunction and control groups. Two weeks after the first evaluation, 15 of the cases filled out the scale again without any treatment intervention. Known-groups method was used in validity analysis. Floor-ceiling effect, test-retest method, item-total score correlation and internal consistency analysis were used in reliability analyses. Results Cronbach's alpha coefficient was 0.714 for the entire questionnaire. The test-retest reliability coefficient for the total scale was determined as 0.792, indicating correlation between the two questionnaires completed by the same patient over time. In the Eustachian tube dysfunction group, total and each item scores were found significantly higher than the control group (p &lt; 0.001). Conclusion The Turkish version of Eustachian tube dysfunction questionnaire-7 was found to be highly valid and reliable. This scale is recommended to use for screening of Eustachian tube dysfunction and evaluating treatment outcome.

title: Association between innovation competences and competitiveness in the brazilian electromedical device industry

description: Abstract The aim of this article is to investigate the existence of a causal relationship between innovation competences and competitiveness in electromedical device manufacturers operating in Brazil. A survey was conducted in 2015 with 34 companies, and the data gathered were analyzed qualitatively and quantitatively. Innovation competences were addressed from two perspectives. In the first, the capacity to follow, predict, and act on market developments was the best developed capability, while the capacity to sell new products was the least developed. In the second, technical competences were found to be better developed than relational and organizational ones. Concerning competitiveness, fewer than half the respondents reported improved performance in at least one of the seven indicators evaluated. Considering the two variables together, no statistical correlation was found between innovation competences and competitiveness using Spearman’s Rank-Order Correlation Test. As such, the competitiveness of the companies from the sample under study was understood as being more strongly associated to their commercial performance, itself affected by their capacity to fulfill regulatory requirements.

title: Gastroprotective and antioxidant effects of Eremurus spectabilis Bieb. methanol extract and its isolated component isoorientin on indomethacin induced gastric ulcers in rats

description: Abstract Purpose: To investigate the gastroprotective effect of methanol extract of E. spectabilis and its major component isoorientin. Methods: Effects of isoorientin and methanol extract of E. spectabilis were investigated in indomethacin-induced gastric damage model on rats. Famotidine was used as the standard antiulcer drug. Numerical density of ulcer areas and oxidative status were determined on stomach tissues of rats. Results: All doses of isoorientin and methanol extract decreased MDA level and increased SOD activity and GSH levels in the stomach tissue of rats. When numerical density of ulcer areas were analized, the 500 mg/kg dose of methanol extract (84%) exhibited a similar effect to 20 mg/kg dose of standart drug famotidine (87%). Conclusions: The gastroprotective effects of E. spectabilis and its major constituent isoorientin in rats for the first time. Detailed analyses suggested that potential antioxidant activity of both plant extract and isoorientin mediates the gastroprotective effect.

title: KYPHOPLASTY AND VERTEBROPLASTY IN THE TREATMENT OF OSTEOPOROTIC VERTEBRAL FRACTURES

description: ABSTRACT Objective: To compare these procedures in the treatment of osteoporotic vertebral compression fractures. Methods: Patients who underwent vertebral augmentation procedures between March 2010 and October 2016 were selected for the study. Kyphosis, anterior vertebral height, Oswestry Disability Index (ODI), Visual Analog Scale (VAS), number of portals, cement volume, and complications were recorded. The results were analyzed by difference of the means. Results: Sixty-eight patients were selected, accounting for 105 procedures. A statistically significant improvement was observed in VAS and ODI with both procedures (p&lt;0.001) without statistically significant difference between them, regardless of the number of portals or cement applied. There was a high correlation between kyphosis correction and ODI improvement (p =0.012). Conclusions: Both vertebroplasty and kyphoplasty are effective procedures for the treatment of vertebral compression fractures. We found no significant difference between both procedures. The high correlation between improvement of kyphosis and ODI suggests that these procedures are better than conservative treatment to improve the quality of life of patients, however more studies are required to reach a final conclusion. Level of Evidence III; Retrospective comparative study.

title: EPIDEMIOLOGICAL PANORAMA OF ORTHOPEDIC SPINE PATHOLOGY IN MEXICO

description: ABSTRACT Objective: To determine the epidemiology of orthopedic spine pathology in a national reference hospital in Mexico. Methods: Retrospective, observational and cross-sectional study, using the database and hospitalization census of the orthopedic spine service from January 2009 to December 2016. The data analysis was performed with SPSS version 22 measuring the central frequency and percentages. The demographic variables age and sex, and those related to the diagnosis, type of pathology, affected segment and degrees of affection were obtained. The sampling technique was non-probabilistic sampling by convenience of consecutive cases. Results: We analyzed 7,771 cases: 50.34% males, with a mean age of 53.51 years. The prevalence of the most frequent diseases in hospitalized patients was stenosis of the lumbar canal with 25.85% (1,834 patients), followed by lumbar disc herniation (23.12%), spondylolisthesis (22.63%), cervical spondylotic myelopathy (8.76%), lumbar pain and lumbosciatalgia (4.10%), cervical disc herniation (3.96%), primary infection (3.80%), loosening of material (3.16%), spinal tumors (2.53%) and cervical instability (2.04%). Conclusions: This is the largest series of cases of spinal pathology treated in a hospital in Latin America. The most frequent condition was the stenosis of the lumbar canal, the most affected segment was the lumbar, and the most affected age group was 51 to 60 years. The estimate is an increase in the incidence of spinal diseases, so it is necessary to identify the risk factors and the behavior of each disease for its prevention. Level of Evidence IV; Retrospective, observational and descriptive study.

title: Review of post bariatric surgery effects on common genitourinary physiology

description: ABSTRACT Background: Obesity is a worldwide challenging health problem. Weight loss through medical management of obesity has not always been successful, thus, giving rise to the need for surgical intervention. Bariatric surgery has been shown to be helpful for morbidly obese patients. However, studies have also shown the effect of surgery on stone formation, fertility and erectile function. This review summarizes the main findings of several studies that analyze stone formation and fertility in men as well as erectile function post bariatric surgery. The underlying pathophysiologic alterations post bariatric surgery include increased absorption of oxalate leading to hyperoxaluria, hypocitraturia and increased urinary calcium oxalate supersaturation. Contradicting data exist on the effect of bariatric surgery on fertility and erectile function. Further studies are needed to analyze the mechanisms.

title: Genetic Risk Analysis of Coronary Artery Disease in a Population-based Study in Portugal, Using a Genetic Risk Score of 31 Variants

description: Abstract Background: Genetic risk score can quantify individual’s predisposition to coronary artery disease; however, its usefulness as an independent risk predictor remains inconclusive. Objective: To evaluate the incremental predictive value of a genetic risk score to traditional risk factors associated with coronary disease. Methods: Thirty-three genetic variants previously associated with coronary disease were analyzed in a case-control population with 2,888 individuals. A multiplicative genetic risk score was calculated and then divided into quartiles, with the 1st quartile as the reference class. Coronary risk was determined by logistic regression analysis. Then, a second logistic regression was performed with traditional risk factors and the last quartile of the genetic risk score. Based on this model, two ROC curves were constructed with and without the genetic score and compared by the Delong test. Statistical significance was considered when p values were less than 0.05. Results: The last quartile of the multiplicative genetic risk score revealed a significant increase in coronary artery disease risk (OR = 2.588; 95% CI: 2.090-3.204; p &lt; 0.0001). The ROC curve based on traditional risk factors estimated an AUC of 0.72, which increased to 0.74 when the genetic risk score was added, revealing a better fit of the model (p &lt; 0.0001). Conclusions: In conclusion, a multilocus genetic risk score was associated with an increased risk for coronary disease in our population. The usual model of traditional risk factors can be improved by incorporating genetic data.

title: The importance of histopathology in the diagnosis of isolated renal sarcoidosis: a case report

description: ABSTRACT Introduction: Sarcoidosis is a systemic inflammatory disease of unknown etiology, characterized by the presence of non-caseating granulomas in several organs; renal impairment alone is a rare condition. When it affects the kidneys, the most prevalent manifestations are hypercalcemia and hypercalciuria. This paper aims to address the topic of renal sarcoidosis, by means of a case report, and reinstate the importance of histopathology in its diagnosis. Methods: The data came from an observational clinical study with a qualitative approach, through an interview with the renal sarcoidosis patient and data from her medical records. Case report: Patient D.M.S., 50 years old, Caucasian, presented with reddish eyes and body pains lasting for fifteen days as first manifestations of the disease. Upon kidney ultrasound scan, we found renal parenchymal nephropathy. Serial renal function and metabolic tests reported anemia and progressive urea and creatinine changes, as well as hypercalcemia and hypercalciuria, confirming acute kidney failure (AKF). A histopathological examination suggested the diagnosis, which was confirmed by clinical, laboratory and histopathological data. There was therapeutic resolution after steroid therapy. Discussion: The symptomatology of sarcoidosis is diverse and often non-specific. Renal manifestation, which usually occurs after organ involvement, is present in less than 5% of patients, and about 1% to 2% of these patients may develop AKF. Conclusions: The use of histopathology together with clinical and laboratory data to diagnose isolated renal sarcoidosis, rule out other etiologies and introduce early treatment is of paramount importance.

title: EFFECTS OF URBAN SPRAWL ON FOREST CONSERVATION IN A METROPOLITAN WATER SOURCE AREA

description: ABSTRACT The clearing of native vegetation in water source areas and its effects on water supply availability have become a major concern in large metropolises. This study examined the spatial and temporal changes in land use and cover and their effects on the conservation of Atlantic Forest in a water source area in the Metropolitan Region of São Paulo that is the second most densely populated territory in Brazil, the municipality of Diadema. Historical maps and trend scenarios were developed by applying the Markov chain in association with cellular automata. Forest conservation was assessed based on a set of landscape metrics of resource availability, fragment isolation, and trends of forest fragmentation. Our findings revealed an increase in urban growth of 37% in the last five decades directly associated to the clearing of 50% of forests in intermediate/advanced stages and 40% in early stages. The main drivers of landscape change were human-modified fields (41%) and net roads (54%). Optimal resource availability was drastically reduced (75%) while isolation increased (361.5%) among existing forest fragments. Therefore, future trends indicate that, without changes in the management of the area, deforestation may occur rapidly and continuously until 10% of forest remains, leading to potential adverse effects on water availability and quality of the Billings Reservoir and the local biodiversity.
