Economic Stability and Choice of Exchange Rate Regimes
The purpose of this paper is to emphasize the importance of Europe's structural problems and governance as the cause of the current euro area crisis. The euro may have led to bubbles, but member economies were not free of trouble before the euro. Many members were losing competitiveness and in need of removing structural rigidities. If anything, the euro was expected to encourage structural reform, by taking away the easy choice of monetary and fiscal expansion. We first discuss the relationship between the single currency and economic stability in Europe. We confirm the asymmetries that remained after the introduction of the euro and then discuss the governance overhaul taking place in Europe today. This overhaul was something that should have been done before introducing the euro, and its advancement may be the silver lining of this crisis. Finally, we touch upon the implications for Asia and Japan, from the point of view of the choice of exchange rate regime as a method to advance necessary reforms
Curative effect of second curettage for treatment of gestational trophoblastic disease - Results of the Belgian registry for gestational trophoblastic disease.
peer reviewedOBJECTIVE: We assessed the curative effect of a second curettage in patients with persistent hCG serum levels after first curettage for a gestational trophoblastic disease (GTD). STUDY DESIGN: This prospective observational study used the data of the Belgian register for GTD between July 2012 and January 2017. We analysed the data of patients who underwent a second curettage. We included 313 patients in the database. Primary endpoints were need for second curettage and chemotherapy. RESULTS: Thirty-seven patients of the study population (12 %) underwent a second curettage. 20 had persistent human chorionic gonadotropin hormone (hCG) elevation before second curettage. Of them, 9 patients (45 %) needed no further treatment afterwards. Eleven patients (55 %) needed further chemotherapy. Nine (82 %) were cured with single-agent chemotherapy and 2 patients (18 %) needed multi-agent chemotherapy. Of the 37 patients, patients with hCG levels below 5000 IU/L undergoing a second curettage were cured without chemotherapy in 65 % versus 45 % of patients with hCG level more than 5000 IU/L. Of the ten patients with a hCG level below 1000 IU/L, eight were cured without chemotherapy. CONCLUSIONS: Patients with post-mole gestational trophoblastic neoplasia can benefit from a second curettage to avoid chemotherapy, especially when the hCG level is lower than 5000 IU/L
The 2017 Regional Election in Catalonia: An attempt to understand the pro-independence vote
This paper tries to unveil the main factors behind the triumph of the proindependence
vote in the 2017 Regional Election in Catalonia. The empirical analysis, which is carried out at the county level and by using a spatial econometric model, reveals that geographical location matters. The estimation results also suggest that the pro-independence vote is mainly linked to the birthplace of individuals. More specifically, it shows that the independence feeling is weaker the higher the share of citizens born outside Catalonia. On the other side, young and highly educated people are more prone to independence. Additionally, it is shown that people working in the public sector are more likely to vote for a political party in favor of Catalonia remaining in Spain, while the opposite happens for those voters working in construction. Finally, the results seem to dispel some myths associated with the role played by the county’s size and level of income on the proindependence vote
The Roles of Fiscal Rules, Fiscal Councils and Fiscal Union in EU Integration
EU-level fiscal rules have not been able to prevent the large-scale accumulation of government debt in many eurozone countries. One explanation was major flaws in the rules. Some of these flaws have now been corrected. But the failure of the rules depended also on fundamental problems of time inconsistency. The same time-inconsistency problems that the rules were designed to address also apply to the rules themselves. Fiscal councils may be subject to less of such problems than rules. Still it is unlikely that a monetary union where bail-outs of governments are part of the system is viable in the long run. The sustainability of the euro may require a restoration of the no-bail-out clause and a strengthening of the banking union in ways that would allow it to cope with the financial repercussions that could arise from allowing government bankruptcies
Alternative Environmental Regulation Schemes for the Belgian Power Generation Sector
This paper discusses the effects of alternative waysof using external cost estimates to regulateinvestments and generation in the electricityproduction sector. Starting from the existing system,four alternatives are considered: emission taxes forthe utility and for independent producers, emissiontaxes limited to the electric utility, emissionpermits limited to the electric utility and finally asystem where only investments are regulated, anddispatch is not. Taking external damage estimates fromthe literature, these alternatives are compared usinga dynamic partial equilibrium model of the Belgianelectricity market for the period 1995–2034. Theefficiency and distribution effects of the alternativeenvironmental policy instruments are quantified.

Ultrasound features using MUSA terms and definitions in uterine sarcoma and leiomyoma : cohort study
Abstract: Objectives Timely and accurate preoperative diagnosis of uterine sarcoma will increase patient survival. The primary aim of this study was to describe the ultrasound features of uterine sarcoma compared with those of uterine leiomyoma based on the terms and definitions of the Morphological Uterus Sonographic Assessment (MUSA) group. A secondary aim was to assess the interobserver agreement for reporting on ultrasound features according to MUSA terminology. Methods This was a retrospective cohort study of patients with uterine sarcoma or uterine leiomyoma treated in a single tertiary center during the periods 1997-2019 and 2016-2019, respectively. Demographic characteristics, presenting symptoms and surgical outcomes were extracted from patients' files. Ultrasound images were re-evaluated independently by two sonologists using MUSA terms and definitions. Descriptive statistics were calculated and interobserver agreement was assessed using Cohen's kappa (with squared weights) or intraclass correlation coefficient, as appropriate. Results A total of 107 patients were included, of whom 16 had a uterine sarcoma and 91 had a uterine leiomyoma. Abnormal uterine bleeding was the most frequent presenting symptom (69/107 (64%)). Compared with leiomyoma cases, patients with uterine sarcoma were older (median age, 65 (interquartile range (IQR), 60-70) years vs 48 (IQR, 43-52) years) and more likely to be postmenopausal (13/16 (81%) vs 15/91 (16%)). In the uterine sarcoma cohort, leiomyosarcoma was the most frequent histological type (6/16 (38%)), followed by adenosarcoma (4/16 (25%)). On ultrasound evaluation, according to Observers 1 and 2, the tumor border was irregular in most sarcomas (11/16 (69%) and 13/16 (81%) cases, respectively), but regular in most leiomyomas (65/91 (71%) and 82/91 (90%) cases, respectively). Lesion echogenicity was classified as non-uniform in 68/91 (75%) and 51/91 (56%) leiomyomas by Observers 1 and 2, respectively, and 15/16 (94%) uterine sarcomas by both observers. More than 60% of the uterine sarcomas showed acoustic shadows (11/16 (69%) and 10/16 (63%) cases by Observers 1 and 2, respectively), whereas calcifications were reported in a small minority (0/16 (0%) and 2/16 (13%) cases by Observers 1 and 2, respectively). In uterine sarcomas, intralesional vascularity was reported as moderate to abundant in 13/16 (81%) cases by Observer 1 and 15/16 (94%) cases by Observer 2, while circumferential vascularity was scored as moderate to abundant in 6/16 (38%) by both observers. Interobserver agreement for the presence of cystic areas, calcifications, acoustic shadow, central necrosis, color score (overall, intralesional and circumferential) and maximum diameter of the lesion was moderate. The agreement for shape of lesion, tumor border and echogenicity was fair. Conclusions A postmenopausal patient presenting with abnormal uterine bleeding and a new or growing mesenchymal mass with irregular tumor borders, moderate-to-abundant intralesional vascularity, cystic areas and an absence of calcifications on ultrasonography is at a higher risk of having a uterine sarcoma. Interobserver agreement for most MUSA terms and definitions is moderate. Future studies should validate the abovementioned clinical and ultrasound findings on uterine mesenchymal tumors in a prospective multicenter fashion.

Analysis of 108 patients with endometrial carcinoma using the PROMISE classification and additional genetic analyses for MMR-D
OBJECTIVES: To apply the Proactive Molecular Risk Classifier for Endometrial Cancer (ProMisE) to a consecutive series of endometrial cancer (EC) patients diagnosed at a tertiary referral center and assign EC specimens to one of four molecular subgroups using immunohistochemistry (IHC) for p53/mismatch repair protein expression and sequencing for Polymerase Epsilon Exonuclease Domain Mutations (POLE-EDM). Mismatch Repair Deficient (MMR-D) cases were more thoroughly investigated to identify underlying somatic or germline genetic defects. METHODS: Hundred-and eight consecutive endometrial cancer patients, diagnosed between March 2017 and April 2019, were subjected to immunohistochemical and molecular analysis, according to ProMisE. IHC for p53 and the mismatch repair proteins (MLH1, PMS2, MSH6 and PMS2) was performed. All patients were also tested for POLE-EDM by Sanger sequencing. In addition, tumor and corresponding normal tissue of cases with abnormal MMR IHC were tested by PCR for microsatellite instability (MSI) (MSI analysis system, Promega). Hypermethylation of MLH1 promotor was tested with (methylation specific) multiplex ligation dependent probe amplification. MMR-D cases were subjected to germline mutation analysis of the mismatch repair genes, using next generation sequencing on MiSeq (Illumina) with the BRCA Hereditary Cancer MASTR Plus, (Multiplicom/Agilent), RNA mutation analysis and MLPA. RESULTS: FIGO classification was stage IA (n = 54), IB (n = 22) II(n = 8), III(n = 18) and IV(n = 6). Of the 33 patients with MMR-D on IHC (31%), 26 showed MLH1 promotor hypermethylation as the probable cause of MMR-D. The remaining 7 patients without MLH1 promotor hypermethylation were referred for germline analysis of Lynch syndrome. Six patients carried a pathogenic germline mutation in one of the mismatch repair genes: MSH6(n = 3), PMS2(n = 1), MLH1(n = 1) and MSH2 (n = 1). Pathogenic POLE-EDM were identified in 7 (6%) patients. Multiple molecular features (POLE-EDM + MMR-D or POLE-EDM + p53 abnormal) were observed in 4 patients (4%). A high concordance between MMR-D and microsatellite instability was observed in our cohort. In cases of a genetic defect in the MMR genes, we do note a large proportion of cases exhibiting microsatellite instability. On the contrary a hypermutation state, as seen in POLE EDM, does not result in accompanied phenotypic changes in MSI status. CONCLUSION: The ProMisE classification proved to be an efficient and easily implementable system. Future research should elucidate the precise biological and prognostic meaning of the cases with multiple molecular markers.status: publishe
Improving Endometrial cancer assessment by combining the new techniqUe of GENomic profiling with surgical Extra uterIne disEase assessment (EUGENIE)
Background: The molecular classification of endometrial cancer revolutionized our knowledge of its biology but so far has not affected our surgical approach. The exact risk of extra-uterine metastasis and hence the type of surgical staging for each of the four molecular subgroups are currently unknown. Primary Objective: To determine the association between molecular classification and disease stage. Study Hypothesis: Each endometrial cancer molecular subgroup has a specific pattern of spread and this pattern of spread could guide the extent of surgical staging. Trial Design: Prospective, multicenter study Major Inclusion/Exclusion Criteria: Participants eligible for inclusion in this study must meet all the following criteria: women ≥18 years with primary endometrial cancer, any histology and stage. Primary Endpoint: Number and site of metastasis in each endometrial cancer molecular subgroup. Sample Size: 1000 patients will be enrolled. Estimated Dates for Completing Accrual and Presenting Results: The trial will last 6 years: 4 years of accrual, and 2 years of follow-up of all patients. Results on staging and oncological outcomes are expected in 2027 and 2029, respectively. Trial Registration: The study has been accepted by UZ Leuven Ethical Committee. Belg. Reg. nr: B3222022000997
