ABSTRACTSilicon carbide power devices are purported to be capable of operating at very high temperatures. Current commercially available SiC MOSFETs from a number of manufacturers have been evaluated to understand and quantify the aging processes and temperature dependencies that occur when operated up to 350°C. High temperature constant positive bias stress tests demonstrated a two times increase in threshold voltage from the original value for some device types, which was maintained indefinitely but could be corrected with a long negative gate bias. The threshold voltages were found to decrease close to zero and the on-state resistances increased quite linearly to approximately five or six times their room temperature values. Long term thermal aging of the dies appears to demonstrate possible degradation of the ohmic contacts. This appears as a rectifying response in the I-V curves at low drain-source bias. The high temperature capability of the latest generations of these devices has been proven independently; provided that threshold voltage management is implemented, the devices are capable of being operated and are free from the effects of thermal aging for at least 70 hours cumulative at 300°C.

OBJECTIVE
The most common form of maturity-onset diabetes of the young (MODY), hepatocyte nuclear factor 1α (HNF1A diabetes: MODY3) is often treated with sulfonylureas that confer a high risk of hypoglycemia. We evaluated treatment with GLP-1 receptor agonists (GLP-1RAs) in patients with HNF1A diabetes.

RESEARCH DESIGN AND METHODS
Sixteen patients with HNF1A diabetes (8 women; mean age 39 years [range 23–67 years]; BMI 24.9 ± 0.5 kg/m2 [mean ± SEM]; fasting plasma glucose [FPG] 9.9 ± 0.9 mmol/L; HbA1c 6.4 ± 0.2% [47 ± 3 mmol/mol]) received 6 weeks of treatment with a GLP-1RA (liraglutide) and placebo (tablets), as well as a sulfonylurea (glimepiride) and placebo (injections), in randomized order, in a double-blind, crossover trial. Glimepiride was up-titrated once weekly in a treat-to-target manner; liraglutide was up-titrated once weekly to 1.8 mg once daily. At baseline and at the end of each treatment period a standardized liquid meal test was performed, including a 30-min light bicycle test.

RESULTS
FPG decreased during the treatment periods (−1.6 ± 0.5 mmol/L liraglutide [P = 0.012] and −2.8 ± 0.7 mmol/L glimepiride [P = 0.003]), with no difference between treatments (P = 0.624). Postprandial plasma glucose (PG) responses (total area under the curve) were lower with both glimepiride (2,136 ± 292 min × mmol/L) and liraglutide (2,624 ± 340 min × mmol/L) compared with baseline (3,127 ± 291 min × mmol/L; P &lt; 0.001, glimepiride; P = 0.017, liraglutide), with no difference between treatments (P = 0.121). Eighteen episodes of hypoglycemia (PG ≤3.9 mmol/L) occurred during glimepiride treatment and one during liraglutide treatment.

CONCLUSIONS
Six weeks of treatment with glimepiride or liraglutide lowered FPG and postprandial glucose excursions in patients with HNF1A diabetes. The glucose-lowering effect was greater with glimepiride at the expense of a higher risk of exclusively mild hypoglycemia.

Abstract
The purpose of this study was to determine the relationship between the head position and the subsequent ease of nasotracheal intubation by using the lightwand device Trachlight (TL). Patients requiring nasotracheal intubation were subdivided into 3 groups according to the intubated head position (group S: sniffing position; group E: extension position; and group N: neutral position). The number of attempts, the total intubation time, and the failures of the TL intubation were recorded. Intubation difficulty by means of TL was assessed by the ordinal 6-point scale. Of the 300 patients enrolled in the study, TL intubation was successful in 91.3% of them. There was no significant difference in the success rate of the first attempt between the groups. No correlation between the ordinal scale and the head position was observed. The total intubation time and the ratio of “unsuccessful” cases were not significantly different among the 3 groups. TL is an effective alternative for patients who require nasotracheal intubation. Our study did not determine the most favorable head position for nasotracheal intubation with the TL, so we recommend that nasotracheal intubation with TL be started with the head in the neutral position and then changed to a more appropriate position, if necessary, on an individual basis.

Abstract
The purpose of this prospective, randomized, single-blind study was to determine the anesthetic efficacy of lidocaine with epinephrine compared to lidocaine with epinephrine plus 0.5 M mannitol in maxillary lateral incisor infiltrations. Forty-one subjects randomly received 2 maxillary lateral infiltrations consisting of a 1.84-mL solution of 36.8 mg lidocaine with 18.4 μg epinephrine (control solution) and a 2.90-mL solution of 36.8 mg lidocaine with 18.4 μg epinephrine (1.84 mL) plus 0.5 M mannitol (1.06 mL) in 2 separate appointments spaced at least 1 week apart. The maxillary lateral incisor was blindly electric pulp–tested in 2-minute cycles for 60 minutes postinjection. No response from the subject to the maximum output (a reading of 80) of the pulp tester was used as the criterion for pulpal anesthesia. Total percent pulpal anesthesia was defined as the total of all pulpal anesthesia readings (at output of 80) over the 60-minute test period. Pain during solution deposition and postoperative pain were also measured. The results demonstrated that a 2.90-mL solution of 36.8 mg lidocaine with 18.4 μg epinephrine (1.84 mL) plus 0.5 M mannitol (1.06 mL) was not statistically significantly superior to a 1.84-mL solution of 36.8 mg lidocaine with 18.4 μg epinephrine. The pain of solution deposition was lower with the lidocaine/mannitol formulation. Postoperative pain was not statistically significantly different between the lidocaine/mannitol formulation and the lidocaine formulation without mannitol. We concluded that adding 0.5 M mannitol to a lidocaine with epinephrine formulation was not significantly more effective in achieving a greater percentage of total pulpal anesthesia (as defined in this study) than a lidocaine formulation without mannitol in the maxillary lateral incisor.

Published: June 2014

Abstract
Offices and outpatient dental facilities must be properly equipped with devices for airway management, oxygenation, and ventilation. Optimizing patient safety using crisis resource management (CRM) involves the entire dental office team being familiar with airway rescue equipment. Basic equipment for oxygenation, ventilation, and airway management is mandated in the majority of US dental offices per state regulations. The immediate availability of this equipment is especially important during the administration of sedation and anesthesia as well as the treatment of medical urgencies/emergencies. This article reviews basic equipment and devices essential in any dental practice whether providing local anesthesia alone or in combination with procedural sedation. Part 2 of this series will address advanced airway devices, including supraglottic airways and armamentarium for tracheal intubation and invasive airway procedures.

Objective.Early intensive treatment is now the cornerstone for the management of rheumatoid arthritis (RA). In the era of personalized medicine, when treatment is becoming more individualized, it is unclear from the current literature whether all patients with RA benefit equally from such intensive therapies. We investigated the benefit of different treatment regimens on remission rates when stratified to clinical and serological factors.Methods.The Combination Anti-rheumatic Drugs in Early Rheumatoid Arthritis (CARDERA) trial recruited patients with RA of less than 2 years’ duration who had active disease. The trial compared 4 treatment regimens: methotrexate monotherapy, 2 different double therapy regimens (methotrexate and cyclosporine or methotrexate and prednisolone) and 3-drug therapy. Clinical predictors included age, male sex, and tender joint count (TJC) and serological biomarkers included rheumatoid factor (RF) and anticitrullinated protein antibodies (ACPA).Results.Patients who were male, over 50 years, had ≥ 6 TJC, were RF-IgM–positive, or ACPA-positive were more likely to achieve remission at 24 months using 3-drug therapy compared to monotherapy (OR 2.99, 4.95, 2.71, 2.54, and 3.52, respectively). There were no differences in response to monotherapy and 3-drug therapy if patients were female, under 50 years, had < 6 TJC, or were seronegative.Conclusion.Early intensive regimens have become the gold standard in the treatment of early RA. Our study suggests that this intensive approach is only superior to monotherapy in certain subsets of patients. Although these are unlikely to be the only predictors of treatment response, our study brings us a step closer to achieving personalized medicine in RA.

Objective.To investigate the risk factors for chronic anterior uveitis in patients with juvenile idiopathic arthritis (JIA).Methods.The clinical charts of patients followed between January 1987 and December 2011 were reviewed to establish whether they had uveitis. Inclusion criteria were a diagnosis of JIA and a disease category of persistent oligoarthritis, extended oligoarthritis, rheumatoid factor-negative polyarthritis, psoriatic arthritis, or undifferentiated arthritis. Risk factors included sex, age at arthritis onset, disease category, and antinuclear antibody (ANA) status. The association of risk factors with occurrence of uveitis was evaluated by survival analysis, with first episode of uveitis as the event of interest, and Cox regression analysis.Results.Of a total of 1189 patients, 278 (23.4%) had uveitis a median of 1.1 years after onset of arthritis. There was no difference in the cumulative probability of developing uveitis between males and females and between patients belonging to different JIA categories, whereas uveitis was strongly associated with age at arthritis onset ≤ 3.5 years and positive ANA. Patients possessing the latter 2 factors in combination had a greater probability of having uveitis than patients who had either of them alone.Conclusion.In our patients, the risk of uveitis was related to younger age at onset of arthritis and presence of ANA, but not to female sex and disease category. This finding suggests that the patients who require the most intensive ophthalmologic screening are those who have early-onset JIA and are ANA-positive, regardless of their sex or disease subtype.

Objective.To determine the diagnostic test performance of location of pain and activity-related pain in identifying knees with patellofemoral joint (PFJ) structural damage.Methods.The Multicenter Osteoarthritis Study is a US National Institutes of Health-funded cohort study of older adults with or at risk of knee osteoarthritis. Subjects identified painful areas around the knee on a knee pain map and the Western Ontario and McMaster Universities Osteoarthritis Index was used to assess pain with stairs and walking on level ground. Cartilage damage and bone marrow lesions were assessed from knee magnetic resonance imaging. We determined the sensitivity, specificity, positive and negative predictive values for presence of anterior knee pain (AKP), pain with stairs, absence of pain while walking on level ground, and combinations of tests in discriminating knees with isolated PFJ structural damage from those with isolated tibiofemoral joint (TFJ) or no structural damage. Knees with mixed PFJ/TFJ damage were removed from our analyses because of the inability to determine which compartment was causing pain.Results.There were 407 knees that met our inclusion criteria. “Any” AKP had a sensitivity of 60% and specificity of 53%; and if AKP was the only area of pain, the sensitivity dropped to 27% but specificity rose to 81%. Absence of moderate pain with walking on level ground had the greatest sensitivity (93%) but poor specificity (13%). The combination of “isolated” AKP and moderate pain with stairs had poor sensitivity (9%) but the greatest specificity (97%) of strategies tested.Conclusion.Commonly used questions purported to identify knees with PFJ structural damage do not identify this condition with great accuracy.

Published: June 2014

Objective.To investigate the prevalence of metabolic syndrome (MetS) and of insulin resistance (IR) in an ethnically homogeneous cohort of established psoriatic arthritis (PsA), and to identify clinical associations of MetS and IR in patients with PsA.Methods.A cohort of 283 patients with PsA all meeting ClASsification for Psoriatic ARthritis (CASPAR) criteria was included. All underwent detailed skin and rheumatologic assessments, along with cardiovascular risk factor evaluation. IR was defined as an elevated homeostasis model assessment (HOMA-IR) value of > 2.5. Severe PsA was defined as the presence of 1 or more of the PsA-related radiographic damage features (peripheral joint erosions, osteolysis, sacroiliitis), and PsA requiring tumor necrosis factor inhibitor therapy.Results.The demographic and clinical characteristics of the cohort were mean age 54.6 ± 12 years, 52% female, mean PsA duration 19 ± 9 years. MetS was present in 44% of the studied patients (n = 283). On multiple regression analysis, a significant association of MetS was noted with more severe PsA (OR 4.47, p < 0.001), higher smoking pack-years (OR 1.03, p = 0.02), and worse EQ-5D scores (OR 1.28, p = 0.02). Data on IR were available for 263 patients, and among them, the mean HOMA-IR was 1.43 ± 1.09. Forty-one patients (16%) had IR. On multiple regression analysis, a significant association of IR was noted with more severe PsA (OR 3.49, p = 0.03), later psoriasis age of onset (OR 1.07, p = 0.001), and higher body mass index (OR 1.22, p < 0.001).Conclusion.Among patients with PsA, MetS and IR are highly prevalent, and are independently associated with the severity of underlying PsA.

Published: June 2014

This paper presents an analysis of the practical implementation of two teaching techniques so-called Problem-Based Learning and Cooperative Learning. These techniques were applied to some courses in the Department of Mechanical and Electrical Engineering and evaluated through assessment rubrics.
In a sample of students and teachers, the assessment rubrics were applied to numerically evaluate the proportion of each course, in which the teacher uses traditional teaching versus teaching for meaningful learning. The results of the presented analysis allow to verify the use of these teaching techniques by professors of the Department of Mechanical and Electrical Engineering.
This activity was developed as a part of the work established by the Institutional Development Plan of the Faculty of Engineering, which includes the strategic objective of developing an innovative educational model in the following ten years.
Netiquette in Electronic Communication

Published: June 2014

Electronic mail and electronic communications systems are considered significant and effective tools of communication. One of the most widespread electronic communication tools is e - mail communication. In order to avoid misinterpretation of the report on the side of the recipient, it is need to pay attention to the writing of e - mail messages as well as to their content.
With the continuous expansion of the use of electronic communication there have gradually developed certain rules of etiquette in electronic communications. The existing rules of the propriety ones are expressed in the term " etiqutte " and are not automatically applied in the new communications environment - media.
For electronic communication, the new rules of etiquette have been stabilised into a term NETIQUETTE. The word netiquette was created by combining words NET (net) and ETIKETA (a set of rules of social behavior and habits). Netiquette constitutes the rules of the behavior of users on a network. Although the netiquette is merely "an unwritten set of rules", their not using can be understood as a type of disrespect.
Analysis of knowledge of domestic and foreign sources as well as results of a survey confirmed the justification of paying attention to the education of individuals in NETIQUETTE, irrespective of the degree of education.

Published: June 2014

Increasing demand for high quality and reliable operation of the telecommunication network services and its applications have been the main challenges of the telecommunication network providers in the last decade. In this paper, a remote online testing facility (Intact – Intelligent Test Automation and Configuration Tool) is introduced that proposes a solution for telecommunication network providers to meet demands and to ensure business services as well as network related services (circuit switched and packet switched) operate efficiently.
This paper presents a particular solution of remote testing based on the automated functional “End to End” testing approach. “End to End” starts by configuring service properties, subscriber record and service logic on one hand. On the other hand several hundred call scenarios can be executed fully automatically. Moreover the call detail records written by the network elements are verified automatically too. Hence a test description and web automation language was developed which is very easy to learn. This testing approach improves test speed and quality leading to reduced risk and investment on test procedure. As a result, the proposed solution of a remote automated online test system aims to overcome higher cost, longer time to market periods and increased effort in testing.

Abstract
Macrophage accumulation is not only a characteristic hallmark but is also a critical component of pulmonary artery remodeling associated with pulmonary hypertension (PH). However, the cellular and molecular mechanisms that drive vascular macrophage activation and their functional phenotype remain poorly defined. Using multiple levels of in vivo (bovine and rat models of hypoxia-induced PH, together with human tissue samples) and in vitro (primary mouse, rat, and bovine macrophages, human monocytes, and primary human and bovine fibroblasts) approaches, we observed that adventitial fibroblasts derived from hypertensive pulmonary arteries (bovine and human) regulate macrophage activation. These fibroblasts activate macrophages through paracrine IL-6 and STAT3, HIF1, and C/EBPβ signaling to drive expression of genes previously implicated in chronic inflammation, tissue remodeling, and PH. This distinct fibroblast-activated macrophage phenotype was independent of IL-4/IL-13–STAT6 and TLR–MyD88 signaling. We found that genetic STAT3 haplodeficiency in macrophages attenuated macrophage activation, complete STAT3 deficiency increased macrophage activation through compensatory upregulation of STAT1 signaling, and deficiency in C/EBPβ or HIF1 attenuated fibroblast-driven macrophage activation. These findings challenge the current paradigm of IL-4/IL-13–STAT6–mediated alternative macrophage activation as the sole driver of vascular remodeling in PH, and uncover a cross-talk between adventitial fibroblasts and macrophages in which paracrine IL-6–activated STAT3, HIF1α, and C/EBPβ signaling are critical for macrophage activation and polarization. Thus, targeting IL-6 signaling in macrophages by completely inhibiting C/EBPβ or HIF1α or by partially inhibiting STAT3 may hold therapeutic value for treatment of PH and other inflammatory conditions characterized by increased IL-6 and absent IL-4/IL-13 signaling.
