Published: October 2019

<p class="abstract"><strong>Background:</strong> Cartilage tympanoplasty is one of the procedures performed for treatment of tympanic membrane perforation, more so in those cases associated with eustachian tube dysfunction, or failed previous temporalis fascia type 1 tympanoplasty. Palisade cartilage tympanoplasty, initially described by Heerman utilizes strips of conchal cartilage to reconstruct the tympanic membrane.</p><p class="abstract"><strong>Methods:</strong> A retrospective study which was presented with 64 patients who underwent palisade cartilage- fascia type I tympanoplasty and compared their hearing outcome after three years of post-operative period. Indication to perform a cartilage-fascia tympanoplasty was either an atelectatic middle ear or large perforation of the drum or residual or recurrent perforation following previous temporalis fascia myringoplasty. </p><p class="abstract"><strong>Results:</strong> Average pre-operative hearing loss was 37.38±15.04 dB, while post-operative hearing loss was 20.47±8.85 dB, giving an average gain of 17.03 dB. Of 64 patients, 93.7% patients had fully healed neotympanum.</p><p class="abstract"><strong>Conclusions:</strong> Palisade cartilage fascia tympanoplasty is an effective method to ensure graft uptake and at the same time achieve competitive hearing gain. The reliability of this technique lies in its use for recurrent and residual perforations of the tympanic membrane as well as in cases associated with eustachian tube dysfunction.</p>

Authors: Manohar Babu , Abdurahiman Raees 
Published: October 2019

<p class="abstract">Neck node in sub mental area is not uncommon. It occurs mostly due to infective or malignant pathologies in oral cavity. Submental neck node mass due to thyroglossal duct cyst carcinoma is a rare presentation. A 25 year old female presented with a sub mental neck node which was noticed for 6 weeks with no history of fever or any oral lesions. On examination, there was a 1 × 1 cm non tender, firm, mobile sub mental neck node. Fine Needle aspiration cytology (FNAC) of the submental node showed features of metastatic papillary carcinoma from thyroid. Whole body Technitium 99 Pertechnate scan was done to find the primary site and metastases in other neck nodes but failed to find any. After necessary investigations, Total thyroidectomy with sistrunk’s procedure, central compartment clearance and level I clearance, was done. Histopathology report showed papillary carcinoma arising from Thyroglossal duct with metastases in submental lymph node. Different pathologies of a mass occurring in submental area are reactive lymphoid hyperplasia, non-Hodgkin lymphoma, dermoid cyst, abscess, sarcoidosis, hemangioma, and lipoma. Neck mass in submental area occurring due to metastases from thyroglossal duct cyst carcinoma without the swelling in primary is a rare presentation.</p>
An exploratory study of fashion social customer service
Authors: Nobbs Karina , Harnick Gretchen 
Published: October 2019

La tecnología digital ha cambiado la forma de las marcas de moda se comunican con los consumidores y del mercado de sus productos. Por otra parte, el auge de las plataformas de medios sociales en los últimos años ha ayudado a hacer este diálogo más atractivo, convocando a millones de nuevos consumidores a comprometerse con las marcas a nivel personal (PEW, 2013). Un reciente informe de Drapers (2013) sobre la innovación en el mercado del retail en moda, sugiere que el 52 % de las empresas de la moda están utilizando los medios sociales para la interacción con el cliente y la gestión de las relaciones. El objetivo de esta investigación es explorar el uso de los medios de comunicación social para el servicio al cliente. En primer lugar el estudio identificará las razones por las cuales las marcas de moda están utilizando esta plataforma y en segundo lugar, se examinará cómo las marcas las están utilizando. Las empresas que son líderes en este espacio son en su mayor parte empresas de dedicación exclusiva estadounidenses. Como ejemplo, Warby Parker la innovadora marca de anteojos ha estado respondiendo a los problemas de servicio al cliente a través de You Tube clips que actualmente reciben más de 100 visitas (Mashable, 2013). Uno de los grandes retos, y una oportunidad al mismo tiempo, es que los consumidores utilizan las redes sociales para quejarse de los problemas de servicio al cliente (Brandwatch, 2013). ASOS abrió las cuentas de Facebook y Twitter “Estamos aquí para ayudar” para permitir que sus otros canales sociales sean utilizados con fines de relaciones públicas y comunicación minimizando así el contenido negativo en ellos (Bauer, 2013). Conversocial (2013) es un proveedor de atención al cliente especialista en medios sociales, que ha medido que el monitoreo y la respuesta efectiva en el servicio al cliente en redes sociales pueden tener un retorno directo sobre la inversión. Debido a la ausencia de marcos teóricos asociados, el presente estudio adopta un enfoque cualitativo, utilizando fuentes secundarias, el análisis de contenido de las plataformas de medios sociales y entrevistas en profundidad con representantes de marcas de moda con el fin de cumplir el objetivo de la investigación.
Interferencias. Notas sobre el taller como territorio, la regla como posibilidad, la obra como médium
Authors: Suarez Viviana 
Published: October 2019

Quizás es un tema recurrente entre los docentes la suposición de que la relación entre docentes y alumnos ha sido problemática en los últimos tiempos. También se observa que la razón principal de esos cambios en los sistemas de referencia y comunicaciones es la propagación y difusión del uso de tecnologías digitales; habitando nuevo entornos que requieren una interpretación continua para estar simplemente habitados.
Este ensayo propone reflexionar sobre la práctica docente en talleres relacionados con la producción de imágenes artísticas y su relación con el conocimiento; problemas localizados entre episteme y praxis que dicen ser pensados en su articulación; El juego de subjetividades que están en tensión durante el proceso de enseñanza y aprendizaje y el papel del trabajo como objeto de producción intermedia entre la subjetividad y el mundo.
The reciprocity between art and architecture
Authors: Saglam Hakan 
Published: October 2019

The concept of â€˜Artâ€™ in the modern meaning, evaluates within the Enlightenmentâ€™s seminal World of philosophy. Before the Enlightenment architecture and craft were instinctively united fields of creating, almost impossible to detach one from the other. From the beginning of twentieth century the avant-garde of modern architecture were aware of the growing schism between art and architecture and vice versa. The pioneers were writing manifestos, stating that art and architecture should form a new unity, a holistic entity, which would include all types of creativity and put an end to the severance between â€œarts and craftsâ€, â€œart and architectureâ€. Approaching the end, of the first decade of the twenty first century, as communicative interests in all fields are becoming very important, we should once more discuss the relation/ interaction / cross over of art and architecture; where the boundaries of the two fields become blurred since both sides, art and architecture, are intervening the gap between. The aim of this paper is to discuss the examples of both contemporary art and architecture, which challenge this â€œin between gap.â€
Key words: Architecture, art, interaction, in between.

ABSTRACT
For a reliable evaluation of the geo-environmental risk due to naturally occurring asbestos (NOA) during rock excavation of large infrastructure projects, a proper procedure is needed. First, it is necessary to provide a detailed geological model tailored to the NOA-related issues that should drive the rock sampling procedures in order to obtain a representative sampling. The sampling procedures should take into account lithological variability and relative spatial distributions of the rock units. The geological model for NOA should be thus constrained by the main NOA petrofacies occurring in a given geotectonic context, which take into consideration both the mineralogical and structural features, and the identification of NOA homogeneous zones in which the NOA petrofacies are distributed. In this paper, some geo-environmental problems faced during the excavation, in meta-ophiolites, of a long highway tunnel are described. The geological model of the complex setting of the tunnel area (northern Italy, Alps-Apennines junction) is described, focusing on how the NOA-related problems were addressed to allow reliable and detailed estimations of NOA contents for each NOA homogeneous zone and the relevant tunnel layout segment.

Abstract
Background. To investigate the similarities and differences in the structure and function of the central nerve system (CNS) among normal tension glaucoma (NTG), primary open-angle glaucoma with high intraocular pressure (HTG) and primary angle-closure glaucoma (PACG) patients. Methods. Ophthalmic examinations and multimodal magnetic resonance imaging (MRI) were performed. The results of brain functional connectivity (FC) were obtained based on the resting state MRI (rs-fMRI). Voxel-based morphometry (VBM) was applied to analyze structural images to obtain the volume change in the gray matter on 3D T1-weighted imaging (T1WI). Results. We found that frontal lobe FC increased in all three groups. Temporal lobe FC increased in the NTG group, while the FC of the cingulate gyrus and postcentral gyrus increased in the HTG and PACG groups by rs-fMRI. There were no gray matter volume changes in the NTG, while the gray matter of the frontal gyrus changed in the HTG and PACG. Moreover, the gray matter of the precentral gyrus changed in PACG, and the parietal lobe and supra marginal lobe changed in the HTG. The white matter of the inferior parietal lobe and postcentral gyrus increased, while that in the inferior temporal lobe decreased in the NTG group. The white matter in the HTG and PACG groups showed significant alterations in the medial occipital gyrus. Conclusions. The NTG group had different manifestations compared with the HTG and PACG groups regarding changes in brain structure and function, suggesting that pathogenic processes might differ between patients with normal-tension and high-tension POAG.
Comparisons of the Severity between the Kidney and Non-Kidney Disabled Persons by the Number of Chronic Diseases, Out-of-Pocket Expenditure, and Quality of Life: using Korea Health Panel
Authors: Shin Sun Mi , Lee Hee Woo 
Published: October 2019

Abstract
Background: Due to End-Stage Renal Disease, patients who have received dialysis for more than three months or who have already received a kidney transplant are eligible for registration as the Kidney Disabled in Korea. This study aimed to identify the severity between the Kidney and Non-Kidney Disabled by the number of chronic diseases, out-of-pocket expenditure, and quality of life. Methods: This study used the Korean Health Panel from 2009 to 2013. We compared the number of chronic diseases, out-of-pocket expenditure, and quality of life between the Kidney and Non-Kidney Disabled. The Non-Kidney Disabled included heart, liver, respiratory organ, colostomy or urostomy, and epilepsy. Chi-Square, t-test, and ANCOVA were conducted, and then the trends for five years were explored through panel analysis. Results: Of the 308 subjects, 136 (44.2%) had Kidney Disability and 172 (55.8%) had Non-Kidney Disabilities. The number of chronic diseases was 4.7 in the Kidney Disabled and 3.3 in the Non-Kidney Disabled (P<0.001). The annual out-of-pocket expenditure for the Kidney Disabled was $1,310 and that for the Non-Kidney Disabled $812 (P<0.001). Today’s subjective health status for the quality of life (from the worst 0 points to the best 100 points ) was 48.9 for the Kidney Disabled and 60.4 for the Non-Kidney Disabled (P<0.001). In addition, the five years trends for the number of chronic diseases, annual out-of-pocket medical expenditure, and quality of life also differed between the Kidney and the Non-Kidney Disabled (P<0.01). Conclusion: The Kidney Disabled was more serious than the Non-Kidney Disabled in the aspect of the number of chronic diseases, the out-of-pocket medical expenditure, and quality of life. Therefore, it is necessary to consider greater interest in the health care of the Kidney-Disabled people in terms of equity.

Abstract
Background: The importance of global competence has been acknowledged in medical care as well as medical education. However, the existing definition of global competence and the survey tools used to assess global competence are not fully applicable to medical students. This study developed and validated a questionnaire assessing the global competence of medical students and preliminarily explored the underlying factors influencing the global competence of Chinese medical students in eight-year programs . Methods: A questionnaire (Global Competence Assessment Scale for Medical Students, MS-GCAS) was developed following a systematic process , and a cross-sectional multicent er survey was conducted among 10 medical schools in China. A total of 1062 completed questionnaires were analysed . Results: The analysis revealed a four-factor scale consistent with the proposed structure according to the definition of global compet ence . The validity estimates of the four subscales were mostly satisfactory. School education, duration of overseas exchange programs and willingness to work abroad were found to have significant correlation s with global competence .Conclusions: The MS-GCAS is valid and reliable for the assessment of the global competence of medical students in China. Medical schools should take further steps to promote medical students’ global competence .

Published: October 2019

Abstract
Background: Although practice guidelines recommend colorectal cancer surveillance for inflammatory bowel disease (IBD) patients, the natural history of patient with dysplasia is poorly described. Assembling large cohorts of IBD patients with dysplasia is difficult as administrative codes are lacking. The aim of this study was to use natural language processing (NLP) in a large electronic health records (EHR) to identify IBD patients with colonic dysplasia. Methods: We conducted a retrospective cohort study using administrative data from the national Veterans Health Administration (VHA) Corporate Data Warehouse for patients with IBD. Full-text histopathology reports from patients who underwent colonoscopy in the VHA were obtained and a validation cohort was created using a random sample of 2000 reports. An NLP algorithm to identify the presence and grade of dysplasia was developed and performance tested in a validation cohort. The final NLP algorithm was applied to the entire IBD cohort to identify all cases of colonic dysplasia. Results: We identified a total of 44,099 Veterans with IBD, with 22,431 colonoscopy related histopathology reports. NLP had an accuracy of 97.1% for detection of low grade dysplasia, with a precision of 87%, recall of 96.6%, and F- measure of 91.5%. When applied to the entire cohort, a total of 1,762 cases of colonic dysplasia were identified. Conclusions: NLP accurately identifies colonic low-grade dysplasia in IBD patients from a national EHR. NLP can be used to identify large cohorts of IBD patients with dysplasia to further study the natural history and outcomes of colonic dysplasia in patients with IBD.

Published: October 2019

Abstract
Background While special care is given to peri-operative risk assessment and management of the elderly undergoing surgery, psychological aspects have been largely neglected. Escort presence in the operating room (OR) is common practice in the surgical pediatric and obstetric populations, and may be beneficial in the elderly.Aims This study explored the feasibility of family member escort of the elderly into the OR and their presence until induction of anesthesia.Methods Prospective cohort of elderly patients (>70 years) undergoing surgery, who were offered an escort into the OR. The primary endpoint was the proportion of relatives who completed the intervention without feeling dizzy or fainting. Secondary endpoints related to patient, escort and medical staff perception of the process.Results Forty-four sets of patients and escorts completed the process. The primary objective assessing feasibility was concluded successfully. Secondary objectives assessed (1) satisfaction, where 93% of escorts and 75% patients would support a repeat of this process; (2) anxiolysis, where 61.4% of patients reported a reduced level of anxiety; (3) although 68.2% of anesthesiologists agreed this process improved that patients’ well-being, most anesthesiologists and nurses believed this should not become routine practice. Interestingly, most staff support parents escorting a pediatric patient into OR.Conclusion This is the first study exploring the feasibility of escorting the elderly into the OR. It shows a unique insight into patient- and family-centered care of the surgical elderly patient. Escort presence may help alleviate anxiety and increase satisfaction. The medical staff objections must be looked at further.
Association of MBOAT7-TMC4 rs641738 with the risk of hepatocellular carcinoma and persistent infection of hepatitis B virus: a case-control study and meta-analysis

Abstract
Background: Recent studies reported that a hot genetic variant, rs641738 within the membrane bound O-acyltransferase domain containing 7(MBOAT7) and transmembrane channel-like 4 (TMC4) , was associated with several liver diseases. However, results are still conflicting. We conducted this study to explore the role of MBOAT7-TMC4 rs641738 in the risk of hepatocellular carcinoma (HCC) and persistent hepatitis B virus (HBV) infection. Methods: We first performed a case-control study by including 779 HCC cases and 1412 cancer-free controls. Controls are consisted of 678 HBV persistent carriers and 734 spontaneously recovered subjects. Rs641738 was genotyped by MassARRAY platform. Results were analyzed by multivariate logistic regression analysis under five genetic models. Second, we conducted a systematic review and meta-analysis to further explore the role of this variant in HCC risk. Results: Results suggested no association between MBOAT7-TMC4 rs641738 and HCC risk in most genetic models (All P > 0.05), although a marginally significant association was observed in TT vs. CC ( P = 0.037) and recessive model ( P = 0.044). Further meta-analysis including 2135 HCC cases and 4388 controls supported that this variant was not related to HCC risk, even in the TT vs. CC and recessive models. Besides, we identified that this variant also had no influence on persistent HBV infection. Conclusion: Our work highlights that MBOAT7-TMC4 rs641738 is not associated with the risk of HCC or persistent HBV infection. This study provides some clues to identify the “truth” of potential disease-related genetic factors in the post-genome era.
