    Introduction An open approach to thyroidectomies through neck provides good exposure and safe dissection however, the patient still has a scar. Endoscopic thyroid surgery has been practised since the late 90s. The latest addition is the transoral endoscopic thyroidectomy by vestibular approach. Materials and Methods We at our centre performed this surgery on 3 patients. Here we present our initial experience of transoral endoscopic thyroidectomy by vestibular approach (TOETVA). Results Two of the three patients did not have any complication. Diffuse bleeding was encountered during one instance and decision was taken to convert it into an open procedure. Conclusion The preliminary experience of transoral thyroidectomy by vestibular approach shows it to be a feasible and promising ‘scarless’ and ‘minimally invasive’ surgery

    Eremurus persicus (Jaub. & Spach) Boiss. (Asphodelaceae); a little known species of genus Eremurus grows in arid and semi-arid regions, on rocky mountains in Central Asia and Middle East. The species is native and an important medicinal plant used to treat various diseases. In the current study, we examined male meiosis, karyotypic variability, pollen viability and reproductive output of three populations of the target species. All the studied populations have diploid chromosome count of 2n = 2x =14. Meiotic course in majority of the pollen mother cells (PMCs) in all the three populations is not normal due to the presence of desynapsis at diplotene and metaphase-I. Instead of 7IIs most of the PMCs examined reveal varying number of bivalents and univalents. Anaphasic segregation is also affected in few PMCs. Present study also revealed that the species has asymmetric karyotype of 10 long and 4 short chromosomes. Species exhibits fruit abortion that results in extremely low fruit/seed set. The meiotic abnormalities and low fruit/seed set may be attributed to restricted distribution of this important plant species. Present study may prove helpful in devising the conservation and management strategies for this prized plant species

    Meiotic behavior and its implications on the reproductive success of Arnebia euchroma (Royle ex Benth.) I.M.Johnst. (Boraginaceae), an important medicinal plant of Trans-Himalaya

    The present study reports the chromosome number, meiotic behavior and its relation with pollen fertility and seed set of Arnebia euchroma (Royle ex Benth.) I.M.Johnst. The species shows a chromosome count of 2n = 2x = 14. The meiotic abnormalities such as chromatin stickiness, cytomixis, laggard formation, chromosomal bridges, were also observed in the Pollen Mother Cells (PMCs) of the target plant species. The linear model of regression showed a significant reduction of seed set with increasing meiotic abnormality and correlation analysis highlighted positive relationship between pollen viability and seed set. Meiotic abnormalities within the species hinder its reproductive process, causing a decline in reproductive efficiency. This study highlights the importance of addressing these intrinsic factors in future conservation programs to prevent a decline in the species population in nature

    Schwartz Centre Rounds: qualitative exploration of panel members’ experiences within a forensic mental health service

    Schwartz Centre Rounds (SCRs) provide a structured forum for staff from all disciplines to meet and discuss the difficult emotional and social challenges that arise in caring for patients. Research into the implementation of SCRs has shown that staff who attend report increased insight into the emotional and social aspects of care; greater understanding of the roles of their colleagues; improved teamworking and decreased feelings of isolation and stress. However, little research has explored the implementation of SCRs within forensic settings, and no research has focused solely on the experiences of panel members. Three focus groups were facilitated with participants who had participated in a SCR panel within a forensic mental health service. Semi-structured interviews were carried out, audio-recorded and subsequently transcribed. Interpretive phenomenological analysis was utilised to analyse the transcripts, and four key themes were identified. These themes were: feeling vulnerable, the importance of validation, exposure to intense emotional experiences and improved understanding and connection. We conclude that SCRs can be an emotionally challenging but rewarding experience, with the potential to enhance teamworking and general well-being. Limitations and recommendations for future research are also discussed

    LEARN: A multi-centre, cross-sectional evaluation of Urology teaching in UK medical schools

    OBJECTIVE: To evaluate the status of UK undergraduate urology teaching against the British Association of Urological Surgeons (BAUS) Undergraduate Syllabus for Urology. Secondary objectives included evaluating the type and quantity of teaching provided, the reported performance rate of General Medical Council (GMC)-mandated urological procedures, and the proportion of undergraduates considering urology as a career. MATERIALS AND METHODS: LEARN was a national multicentre cross-sectional study. Year 2 to Year 5 medical students and FY1 doctors were invited to complete a survey between 3rd October and 20th December 2020, retrospectively assessing the urology teaching received to date. Results are reported according to the Checklist for Reporting Results of Internet E-Surveys (CHERRIES). RESULTS: 7,063/8,346 (84.6%) responses from all 39 UK medical schools were included; 1,127/7,063 (16.0%) were from Foundation Year (FY) 1 doctors, who reported that the most frequently taught topics in undergraduate training were on urinary tract infection (96.5%), acute kidney injury (95.9%) and haematuria (94.4%). The most infrequently taught topics were male urinary incontinence (59.4%), male infertility (52.4%) and erectile dysfunction (43.8%). Male and female catheterisation on patients as undergraduates was performed by 92.1% and 73.0% of FY1 doctors respectively, and 16.9% had considered a career in urology. Theory based teaching was mainly prevalent in the early years of medical school, with clinical skills teaching, and clinical placements in the later years of medical school. 20.1% of FY1 doctors reported no undergraduate clinical attachment in urology. CONCLUSION: LEARN is the largest ever evaluation of undergraduate urology teaching. In the UK, teaching seemed satisfactory as evaluated by the BAUS undergraduate syllabus. However, many students report having no clinical attachments in Urology and some newly qualified doctors report never having inserted a catheter, which is a GMC mandated requirement. We recommend a greater emphasis on undergraduate clinical exposure to urology and stricter adherence to GMC mandated procedures

    Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

    Get PDF
    Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.

    Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis

    Juxtaposing BTE and ATE – on the role of the European insurance industry in funding civil litigation

    Get PDF
    One of the ways in which legal services are financed, and indeed shaped, is through private insurance arrangement. Two contrasting types of legal expenses insurance contracts (LEI) seem to dominate in Europe: before the event (BTE) and after the event (ATE) legal expenses insurance. Notwithstanding institutional differences between different legal systems, BTE and ATE insurance arrangements may be instrumental if government policy is geared towards strengthening a market-oriented system of financing access to justice for individuals and business. At the same time, emphasizing the role of a private industry as a keeper of the gates to justice raises issues of accountability and transparency, not readily reconcilable with demands of competition. Moreover, multiple actors (clients, lawyers, courts, insurers) are involved, causing behavioural dynamics which are not easily predicted or influenced. Against this background, this paper looks into BTE and ATE arrangements by analysing the particularities of BTE and ATE arrangements currently available in some European jurisdictions and by painting a picture of their respective markets and legal contexts. This allows for some reflection on the performance of BTE and ATE providers as both financiers and keepers. Two issues emerge from the analysis that are worthy of some further reflection. Firstly, there is the problematic long-term sustainability of some ATE products. Secondly, the challenges faced by policymakers that would like to nudge consumers into voluntarily taking out BTE LEI
