Incidence and Predictors of Dysphagia Following Anterior Cervical Discectomy and Fusion: Prospective Observational Study  [PDF]
Yingda Li, Kerry Hitos, Su-Thet Mon, Natalie Knight, Nick Vrodos
Open Journal of Modern Neurosurgery (OJMN) , 2018, DOI: 10.4236/ojmn.2018.81011
Abstract: The incidence of dysphagia following anterior cervical discectomy and fusion (ACDF) reported in the literature varies due to differences in measures and time intervals applied, ranging from nearly 3/4 at 2 weeks to 13% at 12 months. The most commonly used dysphagia scales remain subjective, non-validated, and do not capture functional impact. Various risk factors have been identified, though few consistently reproduced and none studied in an Australasian context. The aims of this study were to use objective and validated measures, assess both traditional and novel risk factors, and determine the impact of dysphagia on dietary status, length of stay and complications. METHODS: Twenty-nine adults undergoing ACDF for degenerative pathologies were enrolled between March and November 2015 in an Australian institution. Bazaz dysphagia scale, Dysphagia short questionnaire, 3-ounce swallow test and dietary status were assessed preoperatively, and 2 days and 6 weeks postoperatively. Descriptive statistics were used to characterise the study sample and logistic regression modelling performed on risk factors. RESULTS: Dysphagia incidence ranged from 85% on day-2 Dysphagia short questionnaire to zero on 6-week 3-ounce swallow. All measures increased at 2 days and fell by 6 weeks. Failing day-2 3-ounce swallow was the only measure associated with modifications in solids (P = 0.06), showing significant linear correlation (P = 0.02). Respiratory comorbidity increased risk of failing day-2 3-ounce swallow by more than 32-fold (OR: 32.4; 95% CI: 1.8 - 587.7; P = 0.019) and scoring moderate or severe on Bazaz by almost 10-times (OR: 9.3; 95% CI: 0.9 - 95.95; P = 0.061). Psychiatric history also increased risk of failing day-2 3-ounce swallow by more than 10-fold (OR: 10.9; 95% CI: 1 - 123.7; P = 0.054). Failing 3-ounce swallow increased length of stay (5 versus 7 days; P = 0.013). CONCLUSIONS: Incidence of dysphagia following ACDF was dependent on the measure used, though all improved over time. The 3-ounce swallow test correlated with dietary modification and length of stay, while respiratory comorbidity posed the most significant risk. This may identify a group of patients who may benefit from early intervention.

Evaluation of Different Electronic Product Code Discovery Service Models  [PDF]
Su Mon Kywe, Jie Shi, Yingjiu Li, Raghuwanshi Kailash
Advances in Internet of Things (AIT) , 2012, DOI: 10.4236/ait.2012.22005
Abstract: Electronic Product Code Discovery Service (EPCDS) is an important concept in supply chain processes and in Internet of Things (IOT). It allows supply chain participants to search for their partners, communicate with them and share product information using standardized interfaces securely. Many researchers have been proposing different EPCDS models, considering different requirements. In this paper, we describe existing architecture designs of EPCDS systems, namely Directory Service Model, Query Relay Model and Aggregating Discovery Service Model (ADS). We also briefly mention Secure Discovery Service (SecDS) Model, which is an improved version of Directory Service Model with a secure attribute-based access control mechanism. Then, we analyze the strengths and limitations of these models, by comparing based on non-functional features such as data ownership, confidentiality, business relationship independence, availability, reliability, implementation complexity, visibility, and scalability. From the analysis results, we have a better understanding of which model is more suitable in what kinds of situations or scenarios. Moreover, we suggest possible improvements and identify possible future add-on applications to SecDS model in the paper.

Creative Education (CE) , 2018, DOI: 10.4236/ce.2018.99095
Abstract: The advantage of technology has paved way for innovation in higher education. Because of being cost-effective, unlimited time and place, the universities from the developing world are also trying to integrate e-learning into their traditional education system. However, as a fundamental process, they require the readiness assessment before their e-learning implementation. Moreover, the evaluation on readiness should be done as on-going process so that readiness movements are able to be confirmed, and necessary preparations in line with their updates can be effectively done. The purpose of this study was to investigate if the e-learning readiness of two Myanmar technological universities are stable or not, and to find out which items happened the highest difference between 2016 and 2017. To examine the changes in e-learning readiness, the paper-based data collection was done using questionnaires and shared toward 648 students in 2016 and 1024 students in 2017. Data analysis was done by indexes of descriptive statistics and independent t-test. Findings reveal that their readiness was a significant decline in 2017. Moreover, the items with highest changes were addressed, and the readiness levels on each studied dimension were also measured. In addition, the study points out blackout problems found in Myanmar universities. Understanding the barriers directed by e-learning readiness encourages Myanmar universities to make an e-learning effort on what kind of strategies and preparation should be emphasized.

International Journal of Network and Mobile Technologies , 2010,
Abstract: Today, as the increasing the amount of using internet, there are so most information interchanges are performed in that internet. So, the methods used as intrusion detective tools for protecting network systems against diverse attacks are became too important. The available of IDS are getting more powerful. Support Vector Machine was used as the classical pattern reorganization tools have been widely used for Intruder detections. There have some different characteristic of features in building an Intrusion Detection System. Conventional SVM do not concern about that. Our enhanced SVM Model proposed with an Recursive Feature Elimination (RFE) and k-Nearest Neighbor (KNN) method to perform a feature ranking and selection task of the new model. RFE can reduce redundant & recursive features and KNN can select more precisely than the conventional SVM. Experiments and comparisons are conducted through intrusion dataset: the KDD Cup 1999 dataset

Surgically Treated Symptomatic Prolapsed Lumbar and Sacral Intervertebral Discs in Females: A Comparative Study of Incidence and Causative Factors and Treatment
Nigerian Journal of Surgery , 2012,
Abstract: Background and Objective: There are various postulated possible causes of surgically symptomatic prolapsed intervertebral discs in the lumbar and sacral regions. They may be acting singularly or collectively. Yet, these factors, which could vary in different environments, have not been satisfactorily confirmed. The intention of this study is to share the experience of the author in the occurrence, possible causative factors, and treatment of surgically symptomatic prolapsed lumbar and sacral intervertebral discs in females, and to compare this experience in Switzerland, Nigeria, and Jamaica using surgery records for a period of over 39 years. Materials and Methods: Records of these cases were examined and analyzed with the intent of comparing the frequency of occurrence and possible causative factors of this lesion in some countries. Results: There were 60 locations in 51 patients in Basel (Caucasian population only), 4 locations in 1 patient in Imo and Ebonyi States (African population only), and none in Jamaica (mixed population). The patients’ ages ranged from 19 to 71 years in Switzerland, and the only patient in Nigeria was 49 years old. Conclusion: The study revealed that surgically treated symptomatic prolapsed lumbar and sacral intervertebral discs in females occurred more in Basel, Switzerland, than in Imo and Ebonyi States of Nigeria and none occurred in Jamaica, West Indies. Racial differences, certain sporting/ recreational activities, smoking, and type of profession could have contributed to the development of this disease.
Case Series of Ruptured Jamaican Berry Aneurysms Four Decades Ago
Nigerian Journal of Surgery , 2011,
Abstract: Objective From our personal experiences, it is our wish to examine the incidence of ruptured intracranial aneurysms about four decades ago in Jamaica, the West Indies, with regards to postoperative deterioration of neurological/psychological functions. Materials and Method The author, while working in Jamaica, the West Indies, from 1975 to 1977 (3 years), operated on 6 cases of ruptured intracranial aneurysms of 5 females and 1 male. The source of these data is from the author's surgery records. Result There were 4 aneurysms from the posterior communicating artery, and 1 each from the anterior communicating artery, and the middle cerebral artery. Their ages ranged from 31 to 64 years. They presented with diverse neurological disturbances. Their aneurysms, which were diagnosed through contrast carotid angiography, were all clipped through fronto-lateral craniotomy under general anaesthesia. The procedures were well tolerated by the patients. There were no complications and no gross additional neurological deficits postoperatively. The wounds had healed by primary intention. The patients were discharged home 12 days postoperatively, the stitches having been removed 2 days earlier. Follow-up checks started about 7 days after discharge. The neurological deficits had cleared about 3 months later. Conclusion Having bled, the aneurysms exposed themselves by causing sudden severe headaches, and various neurological problems, depending on their locations. We found more females than males. The posterior communicating artery aneurysm was predominant. There were no cerebro-vascular spasms postoperatively.

Comparative Studies of the Incidence of Surgically Treated Symptomatic Prolapsed Lumbar and Sacral Intervertebral Discs in Males in Basel (Switzerland), Jamaica (West Indies) and Imo and Ebonyi States (South East Nigeria)
Nigerian Journal of Surgery , 2011,
Abstract: Objective and Background: There are various postulated possible causes of surgically symptomatic prolapsed intervertebral discs in the lumbar and sacral regions. They may be acting singularly or collectively. Yet, these factors have not been satisfactorily confirmed. Therefore, the continued search for predeterminants of this lesion, in males, is hereby being encouraged, and, our views are being presented. Method: From 1971 to 2009, eighty eight (88) locations of symptomatic prolapsed intervertebral discs in the lumbar and sacral regions in 68 males were treated by us in Basel (Switzerland): 67, in Imo and Ebonyi States (Nigeria): 1 and none in Jamaica (West Indies). The clinical features were those of lower back pains, with or without radiation into the lower extremities, sensory loss and paresis of the limbs. There was a case of loss of urinary bladder and ano-rectal control. All lesions were confirmed through cauda-equinograms and treated under general anaesthsia in knee-chest position (MECCA position). The patients were followed for 3 to 6 months postoperatively. Results: In Basel (Caucasian population only), there were 84 locations in 67 patients, 4 locations in 1 patient in Imo and Ebonyi States (African population only) and none in Jamaica (mixed population). Their ages ranged from 23 to 70 years in Basel and the only patient in Nigeria was 67 years old. The patients all tolerated the procedures very well and there were no complications postoperatively. Conclusion: We found surgically treated symptomatic prolapsed lumbar and sacral intervertebral discs in males to have occurred more in Basel, Switzerland than in Imo and Ebonyi States of Nigeria and/or Jamaica, West Indies. Key Words : Comparative, Studies, Symptomatic, Prolapsed, Intervertebral, Discs, Males, Switzerland, Nigeria, Jamaica.
Control tectónico de la red de drenaje de los Andes del norte argentino Tectonic control of the drainage in the Andes of northern Argentina
R. Mon
Revista de la Asociación Geológica Argentina , 2005,
Abstract: Los ríos transversales que drenan la vertiente oriental de los Andes del norte argentino muestran bruscos desvíos hacia cursos longitudinales, inmediatamente al oeste de la traza de grandes cabalgamientos o de los bordes de láminas levantadas por fallas ubicadas en el lado opuesto de ellos. Los ríos desviados colectan otros ríos transversales antes de emerger en la dirección opuesta y de atravesar el frente monta oso. El desvío de los ríos se interpreta como la respuesta al levantamiento progresivo y al crecimiento lateral de cinturones fallados o de anticlinales propagados a lo largo de fallas ciegas. La mayor parte de los ríos de la región fueron desviados, pocos de ellos mantuvieron sus cursos a través de las estructuras en desarrollo. La reorganización del drenaje por el desarrollo de una topografía controlada estructuralmente influyó en la ubicación y en la concentración de los desagües de los ríos en el frente monta oso. Este segmento de los Andes, que se extiende a lo largo de más de 600 km, tiene sólo tres desagües representados por los ríos troncales Bermejo, Juramento y Salí-Dulce. El drenaje evolucionó desde el levantamiento de la Puna (12- 15 Ma), después de la regresión marina final. El desvío de los ríos puede haber empezado después del levantamiento de la Cordillera Oriental (10 Ma) y prosiguió con el levantamiento de nuevas monta as hacia el este. El levantamiento de las cadenas monta osas avanzó de oeste a este. Los cinturones más orientales del Sistema Subandino y de las Sierras Pampeanas septentrionales se levantaron después de los 3 Ma. El levantamiento rápido de los obstáculos tectónicos puede explicar la tendencia al desvío de los ríos de esta región. Transverse rivers draining the eastern flank of the Andes of north Argentina show abrupt diversions to axial courses immediately west of the trace of big thrusts, or the borders of plates uplifted by faults located along the opposite side of them. The diverted rivers gather other transverse rivers before merging in the opposite direction and breaking through the mountain front. River diversion is interpreted as a response to progressive uplift and lateral growth of fault belts or anticlines propagating along blind thrusts. Most of the rivers of the region were diverted; few maintained their courses across growing structures. Drainage reorganization by the growth of structurally controlled topography influenced the location and concentrated the river outlets at the mountain front. This 600 km-long segment of the Andes has only three outlets represented by the trunk rivers Bermejo, Jura
