Surgical treatment of metastatic VIPoma: a case report
No full textVIPoma, a neuroendocrine tumour mostly occurring in the human pancreas and producing high levels of vasoactive intestinal peptide, is a rare disease that presents with a wide spectrum of symptoms, including intense diarrhoea, hypokalaemia, and cardiac complications, with life-threatening consequences. In most cases, metastatic lesions are present at VIPoma diagnosis. Treatment options include symptomatic therapy, chemotherapy, radiation and surgery. Due to its low incidence, there are no evidence-based therapy recommendations to date. Here, we present a case of a 39-year-old woman with severe symptoms due to VIPoma of the pancreas with diffuse hepatic metastasis, who underwent simultaneous resection of the primary tumour, extensive liver resection and radiofrequency ablation. The patient was released in good health and was recurrence-free during 12 months surveillance. According to the existing literature and our own experience, surgical procedures appear to be the most promising therapy option for cases with diffuse hepatic metastasis, offering patients relief from their symptoms and (chemo)therapy-free time

Spatial Integration and Asymmetric Price Transmission in Selected Iranian Chicken Markets
No full textThis study evaluates pattern of price adjustments in selected spatially separated chicken markets in Iran using weekly price data from 1998:17 to 2006:41 including 441 observations in total. The results of Tsay’s test suggest that threshold behavior characterize spatial price linkages among the selected markets that imply on using the threshold models. We use the multi-dimensional (two and three regime) threshold cointegration of TAR and M-TAR models. Our results confirm the different speed of adjustment in response to positive and negative shocks in every case. We also utilize impulse response function to investigate dynamic patterns of adjustments in response to shocks.Spatial Integration, Price Transmission, Threshold Autoregression, Chicken, International Relations/Trade, Marketing,
Perioperative LiMAx Test Analysis: Impact of Portal Vein Embolisation, Chemotherapy and Major Liver Resection
No full textBackground: Postoperative liver failure (PLF) is a severe complication after major liver resection (MLR). To increase the safety of patients, clinical bedside tests are of great importance. However, limitations of their applicability and validity impair their value. Methods: Preoperative measurements of the liver maximum capacity (LiMAx) were performed in n = 40 patients, who underwent MLR (≥3 segments). Matched postoperative LiMAx was measured in n = 21 patients. Liver function was compared between pretreated patients (n = 11 with portal vein embolisation (PVE) and n = 19 patients with preoperative chemotherapy) and therapy naïve patients. The LiMAx values were compared with liver-specific blood parameters and volumetric analysis. Results: In total, n = 40 patients were enrolled in this study. The majority of patients (n = 33; 82.5%) had high preoperative LiMAx values (>315 µg/kg/h), while only seven patients (17.5%) had medium values (140–315 µg/kg/h), and none of the patients had low values (p > 0.05). The preoperative LiMAx values were significantly higher than the matched postoperative values on postoperative day 1 (p n = 12) showed a continuous increase until 14 days after surgery. In the patients with postoperative complications, a decrease in the LiMAx was associated with a prolonged recovery. Conclusions: For patients undergoing MLR within the 0.5% rule, which is the clinical gold standard, the LiMAx values do not offer any additional information. Additionally, the LiMAx may have reflected liver function, but it did not deliver additional information regarding postoperative liver recovery. The clinical use of LiMAx might be relevant in selected patients beyond the 0.5% rule
Reliability Assessment and Energy Modeling for Alberta's Oil Sands Surface Mining Equipment
No full textAlberta’s surface mining sector is one of the largest energy-consuming industries in Canada, and so oil sands mining equipment performance has a significant impact on the economy. To achieve more sustainable oil sands mining production in Alberta, one of the influential factors is the improvement of the reliability of mining equipment. Through these reliability improvements, costs, energy consumption, and greenhouse gas (GHG) emissions can be mitigated. Energy consumption and equipment reliability have considerable risk associated with some main subsystems, and this risk must be determined in order to calculate the effect on expected operating cost. When mining equipment reliability improves, not only can costs associated with maintenance be reduced, but also energy consumption. As well, emissions quality can be improved through better maintenance, which in turn mitigates GHG emissions. The objective of this research is to develop a demand tree, the reliability modeling for oil sands mining equipment, and make a link between energy consumption and reliability. To determine how much energy, cost, and GHG emissions can be reduced through improving equipment reliability, techniques of equipment risk assessment and reliability were studied. In addition, “reference scenarios” for improving the reliability in mining equipment were identified and developed. A probabilistic Bayesian belief network (BBN) method was used for the reliability analysis. The integrated energy-reliability (E-R) model developed for oil sands mining equipment provides a detailed reliability-energy analysis. This model helps to understand the relationship between energy and reliability, and clarifies the amount of energy consumption and energy saving possible through improving the reliability of equipment. The E-R model was developed for four discrete states of reliability: State 1, the mining equipment is fully operational (reliability equals 1); State 2, the equipment operates under expected reliability (as defined by manufacturer); State 3, the equipment operates under low or limited reliability (also known as partial reliability); and State 4, the equipment fails. Partial reliability was calculated for the major subsystems of the mining equipment used in surface mining of bituminous sands, and their associated energy consumption, based on the Markov degraded multi-state model under three states, which are described as: State 1, the system operates under expected reliability; State 2, the system operates under low or limited reliability; this is also known as partial reliability; and State 3, the system fails. LEAP software was used to calculate final energy consumption by each main subsystem for the study period of forty years. It was assumed that the emissions changed only due to change in energy consumption, although partially reliable equipment may have higher specific emissions as well. The E-R model outcomes suggest that energy demand for equipment at current production rates will be reduced by an average of 603.5 million GJ, 1,151.40 million GJ, 1,125.53 million GJ, and 1,732.73 million GJ by year 2050 for states 1, 2, 3, and 4, respectively. Average annual as-spent cost savings of 60 Billion Canadian Dollars, 78 Billion Canadian Dollars, 99 Billion Canadian Dollars, and 158 Billion Canadian Dollars were obtained by year 2050 for operating in states 1, 2, 3, and 4. In addition, GHG emissions will be mitigated by an average of 27 million Metric Tons CO2 equivalent, 77 million Metric Tons CO2 equivalent, 75 million Metric Tons CO2 equivalent, and 105 million Metric Tons CO2 equivalent by year 2050 for states 1, 2, 3 and 4
Unemployment insurance in Algeria : implications for a labor market in transition
No full textTo predict how Algeria's unemployment crisis will evolve, the author evaluates the Algerian unemployment insurance system's ability to finance itself, to affect employment decisions, and promote enterprise restructuring. The main conclusion is that industrial restructuring has serious and persistent implications for the labor market. In an environment where many equilibria are possible, there is a real danger of reaching a high unemployment equilibrium. The big-bang experience of structural adjustment in Central and Eastern Europe transition economies resulted in large-scale unemployment. Despite considerable restructuring progress, structural rigidities still exist in the labor market, and long-term unemployment has persisted. One advantage of the big-bang approach is adjustment speed, but the resulting unemployment may be too costly for Algeria's economy, especially if it persists. A more modern mixed bang approach would incorporate active employment measures to mitigate entrenched unemployment. The policies will maintain or enhance human capital through work, so idle workers don't lose their skills. Flex-time arrangements would help workers maintain an attachment to the labor force. However minor, such work would help workers avoid the traps of long-term unemployment. Two striking conclusions emerge from the Central and Eastern European experience: a) unemployment is not essential to enterprise restructuring and labor market adjustment;and b) growing long-term unemployment is self-fulfilling and results in higher and persistence unemployment. Although active employment measures are costly and have relatively low rates of return in the short run, they can be marginally effective as part of a long-term strategy.Health Economics&Finance,Labor Policies,Environmental Economics&Policies,Labor Markets,Economic Theory&Research,Environmental Economics&Policies,Labor Markets,Economic Theory&Research,Health Economics&Finance,Banks&Banking Reform
How Can Risk Science Contribute to Risk Education for Children and Teenagers? Exploring Emerging Practices
No full textRisk education is an emerging and interdisciplinary topic. Children and teenagers need risk education to enhance their abilities for decision making under the complex and uncertain conditions of today’s world. Observations and performed practices have shown that various perspectives toward fundamental concepts of risk education resulted in a lack of a unified basis. The study aims to determine how risk science can contribute to risk education for creating a unified scientific basis. For this aim, the purpose is to know how the basic pillars of risk science are reflected in performed practices of risk education.
Participating at the international Risk Science and Decision Science for Children and Teenagers Conference in the Netherlands in 2018, Canada and the Netherlands were identified as the pioneers in performing practices of risk education. To gain more information, some relevant practices from some other countries were also examined. Semi open-ended interviews were conducted. Data were collected through interview responses as well as observations and discussions during the conference.
Results show that despite the fact that some fundamental concepts of risk science have been introduced to students in practices of risk education, they are not introduced or reflected sufficiently. While most of the practices in the Netherlands focus on fundamental concepts and technical risk assessment, they are not reflected in the practices of Canada or other countries. Moreover, in these practices, some of the basic pillars of risk science such as risk perception and risk communication have been neglected completely. Risk science can contribute to risk education by providing clear and systematic definitions and descriptions of fundamental risk concepts. Moreover, it clarifies the limitations of quantitative risk assessment by reflecting the principles of risk perception. Hence, risk education will be capable of improving children’s and teenagers’ abilities to have better communication skills and to have an active role in their society
Corporate communication as a governance mechanism: A content analysis of corporate public disclosures
No full textCorporate communication efforts have mainly been viewed as a by-product of governmental regulations and board of directors’ oversight. In this paper, we examine the role of corporate communication as a stand-alone governance mechanism. We introduce a new business-related dictionary and conduct automated textual analysis of over 150,000 electronic documents filed by a sample of firms listed on the S&P/TSX Composite Index from 1999 to the end of 2014. Our findings demonstrate the governing role of corporate communication by documenting the adverse market effects of deviations from the expected level of communication. Moreover, as a governance mechanism, corporate communication shows substitution/complementary relationships with other established governance mechanisms. In addition, we find a non-linear relationship between a firm’s communication efforts and its value and risk levels. Results are robust after controlling for major corporate events (M&A, spin-offs, financial distress and bankruptcy, and significant lawsuits). These findings contribute to corporate governance literature and the understanding of agency theory predictions of communications and disclosures’ economic effects
