A different appetite for sovereignty? Independence movements in subnational island jurisdictions

Local autonomy in a subnational jurisdiction is more likely to be gained, secured or enhanced where there are palpable movements or political parties agitating for independence in these smaller territories. A closer look at the fortunes, operations and dynamics of independence parties from subnational island jurisdictions can offer some interesting insights on the appetite for sovereignty and independence, but also the lack thereof, in the twenty-first century.peer-reviewe

Effects of Oral, Vaginal, and Transdermal Hormonal Contraception on Serum Levels of Coenzyme Q10, Vitamin E, and Total Antioxidant Activity

The use of the transdermal contraceptive patch is associated with greater bioavailability of ethinyl estradiol (EE) compared with contraceptive vaginal ring or oral contraceptives (OC). We compared the influences of three contraceptive methods (OC, vaginal ring, and transdermal patch) on serum levels of coenzyme Q10, α-tocopherol, γ-tocopherol and total antioxidant capacity in premenopausal women. Blood samples from 30 premenopausal women who used hormonal contraception for at least 4 months were collected. Forty subjects who did not use any contraception were studied as control. Serum levels of coenzyme Q10, α-tocopherol and γ-tocopherol were measured by high-pressure liquid chromatography. Serum samples were also assayed for total antioxidant capacity (TAOC). Serum levels of coenzyme Q10 and α-tocopherol were found to be significantly lower (P < .05) in all three contraceptive users compared with controls. Contraceptive patch users had the lowest levels of coenzyme Q10 levels compared with normal subjects. Serum TAOC levels were significantly lower (P < .05) among the contraceptive user groups. Alterations in coenzyme Q10 and α-tocopherol induced by hormonal contraception and the potential effect(s) of exogenous ovarian hormones should be taken into consideration in future antioxidant research

Taxing the powerful, the rise of populism and the crisis in Europe: the case for the EU Common Consolidated Corporate Tax Base

Contemporary populism is rooted in a crisis of legitimacy. Corporate taxavoidance by multinationals is one cause of that crisi s. Although states tend to beincreasingly formally committed to tackling avoidance, they do so in a system thatpromotes contradictory sets of behaviour. This tends to undermine attempts to solvethe problem of avoidance unless a more transformative collective approach is taken.Ironically, despite its own democratic deficit, the European Comm ission has taken aleading role in promoting such a solution: the Common Consolidated Corporate TaxBase (CCCTB). In this paper, I set out the case for ‘unitary taxation’ based on theCCCTB and state some of its current problems. The problem of corporation taxraises a basic issue in terms of who is sovereignty for, and solving the problemprovides an important contribution to legitimacy of both the state and the EU

Periprosthetic fracture (PF) after primary total hip replacement (THR) is an uncommon but potentially devastating complication. We analysed data on 257,202 primary THRs with cemented stems and 390 linked first revisions for PF recorded in the National Joint Registry (NJR) of England and Wales to determine if cemented femoral stem brand was associated with the risk of having revision for a PF after primary THR. All cemented femoral stem brands with more than 10,000 primary operations recorded in the NJR were identified. The four most commonly used cemented femoral stems were: Exeter V40 (n=146,409), CPT (n=24,300), C-Stem (n=15,113) and Charnley (n=20,182). We compared the revision risk ratios due to PF amongst the stems using a Poisson regression model adjusting for patient factors. Compared to the Exeter V40, the age, gender and ASA grade adjusted revision rate ratio for the cemented CPT stem was 3.89 (95%CI 3.07,4.93), for the C-Stem 0.89 (95%CI 0.57,1.41) and for the Charnley stem 0.41 (95%CI 0.24,0.70). Limitations of the study include incomplete data capture, analysis of only PF requiring revision and that observation does not imply causality. Nevertheless, this study demonstrates that the choice of a cemented stem is associated with the risk of revision for PF. </p

Radiation-Tolerant Custom Made Low Voltage Power Supply System for ATLAS/TileCal Detector

This paper describes custom made Low Voltage Power Supply (LVPS) system developed for the ATLAS – TileCal detector of the LHC (The Large Hadron Collider) particle accelerator at CERN, Geneva. The system is based on the use of only COTS (Commercial of The Shelf) components, is qualified to be radiation tolerant up to 40krad, and can operate in external DC magnetic field above 0.02 Tesla. The LVPS design described in this paper has been developed and produced for the ATLAS TileCal detector during the years 2001 – 2007

Patients Generally May Return to Driving 4 Weeks After Hip Arthroscopy and 6 Weeks After Knee Arthroscopy: A Systematic Review and Meta-analysis

Purpose: To consolidate the evidence from the available literature and undertake a meta-analysis to provide a reference for physicians to make evidence-based recommendations to their patients regarding the return to driving after hip or knee arthroscopic procedures. Methods: A systematic review was conducted using Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. The OVID, Embase, and Cochrane databases were searched through June 2020 for articles containing keywords and/or MeSH (Medical Subject Headings) terms “hip arthroscopy” and “knee arthroscopy” in conjunction with “total brake response time” or “reaction time” in the context of automobile driving. A title review and full article review were performed to assess quality and select relevant articles. A meta-analysis of qualifying articles was undertaken. Results: Eight studies met the inclusion criteria for meta-analysis of brake reaction time (BRT). Meta-analysis of all knee BRTs showed times slower than or equal to baseline BRTs through 5 weeks, with a trend of improving BRTs from 6 to 10 weeks (weeks 8 and 10 were significant, P < .05). Among all hip BRTs, week 2 showed times slower than baseline BRTs, but after week 4, a trend toward faster BRTs was observed through week 8 (week 8 was significant, P < .05). Conclusions: BRTs met baseline or control values and continued to improve after 6 weeks after knee arthroscopy and after 4 weeks after hip arthroscopy. On the basis of these results, it would be safe to recommend a return to driving at 6 weeks after knee arthroscopic procedures and 4 weeks after hip arthroscopic procedures. Clinical Relevance: These results can be used by surgeons to base their recommendations on to provide guidance for their patients on the resumption of driving. Although BRT is an important aspect of driving ability, there are additional factors that need to be taken into consideration when making these recommendations, including cessation of opioid analgesics, strength of the surgical limb, and range of motion

A systematic review and meta-analysis of trainee- versus consultant surgeon-performed elective total hip arthroplasty

Total hip arthroplasty (THA) is one of the most commonly performed orthopaedic procedures. Some concern exists that trainee-performed THA may adversely affect patient outcomes. The aim of this meta-analysis was to compare outcomes following THA performed by surgical trainees and consultant surgeons. A systematic search was performed to identify articles comparing outcomes following trainee- versus consultant-performed THA. Outcomes assessed included rate of revision surgery, dislocation, deep infection, mean operation time, length of hospital stay and Harris Hip Score (HHS) up to one year. A meta-analysis was conducted using odds ratios (ORs) and weighted mean differences (WMDs). A subgroup analysis for supervised trainees versus consultants was also performed. The final analysis included seven non-randomized studies of 40 810 THAs, of which 6393 (15.7%) were performed by trainees and 34 417 (84.3%) were performed by consultants. In total, 5651 (88.4%) THAs in the trainee group were performed under supervision. There was no significant difference in revision rate between the trainee and consultant groups (OR 1.09; p = 0.51). Trainees took significantly longer to perform THA compared with consultants (WMD 12.9; p < 0.01). The trainee group was associated with a lower HHS at one year compared with consultants (WMD -1.26; p < 0.01). There was no difference in rate of dislocation, deep infection or length of hospital stay between the two groups. The present study suggests that supervised trainees can achieve similar clinical outcomes to consultant surgeons, with a slightly longer operation time. In selected patients, trainee-performed THA is safe and effective
