A study of 386 potential and current members of the accounting profession in Australia and South‐East Asia provides evidence of the importance of three attributes – brand/reputation, international ...recognition of qualifications and career opportunities – in the decision to join a professional accounting body. While these attributes are important, logit regression models indicate that they are not discriminatory in the choice of professional body and suggest a perception of a collective, undifferentiated accounting profession. The marketing of brand/reputation and membership benefits may be a more efficient and effective strategy in attracting members and differentiating the profession if undertaken by a combined or coordinated professional body.
To overcome the disadvantages of two-round nested PCR, we developed a simple and robust closed single-tube nested PCR method (antisense PCR). The method uses antisense oligonucleotides that carry a ...5′ tag and that can potentially hybridize to the 3′ ends of the outer primers, depending on the annealing temperature. During initial cycles, which are performed at a high annealing temperature, the antisense oligonucleotides do not hybridize and amplification is directed by the outer primers. During later cycles, for which the annealing temperature is decreased, the outer primers hybridize to the antisense oligonucleotides, extend to produce sequences that are mismatched to the amplicon templates, and consequently become inactivated, whereas the inner primers hybridize to the amplicon templates and continue amplification. Antisense quantitative PCR (qPCR) was compared with one-round qPCR for real-time amplification of four PCR targets (
BCR,
APC,
N-RAS, and a rearranged
IGH gene). It had equal amplification efficiency but produced much less nonspecific amplification. Antisense PCR enables both endpoint detection and real-time quantification. It can substitute for two-round nested PCRs but may also be applicable to instances of one-round PCR in which nonspecificity is a problem.
Decision making in elite level sporting competition is often regarded as distinguishing success from failure. As an intricate brain-based process it is unlike other physical processes because it is ...invisible and is typically only evidenced after the event. This case study shows how an individual achieved great success in elite level professional football through consistent positive decision making on and off the field of play. Through prolonged interviewing, Gary Neville, a player from Manchester United Football Club, explored personal behaviours, the structure and activities of deliberate practice and his professional choices in match preparation. His career-long devotion to purposeful organised practice was focused on cognition, physical preparation, context-relative physical action and refined repetition to optimise his mental comfort while enhancing his match day performances. This approach was underpinned by diligent personal and collective organisation and by concerted action. Results provide an insight into the categorical nature of his deliberate practice, sport-specific information processing and match-based decision making. At the operational level, his process was mediated by a complex mental representation of ongoing and anticipated game situations; these representations were continuously updated during each match. Allowing for the limitations of the design, implications are provided for developmental and educational coaching, match preparation, deliberate practice activity and improved use of the performance analysis software packages in professional football.
Abstract Background The purpose of this study was to determine the extent to which summary index scores from the short form Parkinson's Disease Questionnaire (PDQ-8) replicate those from the parent ...form (PDQ-39) in a longitudinal study. Methods Longitudinal data gained from the PD-MED trial were examined (n = 1867), to determine the extent the PDQ-8 replicates results from the PDQ-39 at baseline and follow up. The sensitivity to change of the PDQ-8 was also compared with that of the PDQ-39. Finally, results on the two measures were compared with those from the Hoehn and Yahr (HY) clinical staging scale. Results Results of the Single Index summary score gained from the PDQ-8 were found to closely replicate those gained from the PDQ-39 at each of the three time points. Furthermore at each time point the intraclass correlation coefficient between the two measures was very high (ICC range 0.93–0.96). Similarly, the two measures gave very similar accounts of change (e.g. from baseline to follow up at one year effect sizes were 0.18 for the single index calculated using the PDQ-39, and 0.09 when calculated using the PDQ-8). Similar levels of correlation were found between the two indices when correlated with the HY scale. Conclusions The PDQ-8 closely replicates results gained from the PDQ-39 when calculating single indices. In instances where a single summary score of the impact of PD on self-reported quality of life is needed, it is likely the PDQ-8 will provide reliable and accurate information.
Background
The diagnosis of Lyme disease relies on the accurate diagnosis of erythema chronicum migrans (ECM) because serologic tests, culture, and polymerase chain reactions are often inaccurate. ...Although ECM is classically associated with a targetoid rash, there are many variants of this lesion. These variants of ECM are often initially diagnosed as cellulitis or spider bite reactions and treated with oral antibiotics. Inappropriate treatment further delays the diagnosis of Lyme disease, leading to late complications.
Methods
We present four cases of vesiculobullous and hemorrhagic ECM, a less common variant of ECM.
Results
All four patients had a history of exposure to wooded areas in Massachusetts during the summer months. In these patients, ECM presented with central vesicles and bullae with hemorrhage, crusting, and in some cases necrosis. Serologic testing was positive in three of the four cases at presentation. In one case, microscopic examination of a skin biopsy showed epidermal spongiosis with parakeratosis, focal necrosis, papillary dermal edema, erythrocyte extravasation, and a superficial and deep perivascular lymphocytic infiltrate with neutrophils and eosinophils of the dermis. No fungal organisms or bacteria were identified. All four patients were treated with doxycycline with complete resolution of symptoms.
Conclusions
It is important to recognize the vesiculobullous and hemorrhagic variants of ECM in order to minimize the provision of inappropriate antibiotic treatment for other diagnoses. Early diagnosis of ECM and the initiation of appropriate antibiotics may prevent late complications of Lyme disease.
Abstract Aims The present study aims to investigate patterns of beta-blocker usage in a national primary care cohort. Methods and results This is a retrospective cohort study utilising the UK General ...Practice Research Database from 2004 to 2008. Inclusion criteria were (i) a first diagnosis of chronic heart failure (CHF), myocardial infarction (MI) or angina, and (ii) first-ever prescription of beta-blocker on or after 1st April 2004. Outcome measures were discontinuation of beta-blockers over time, initiation dosages, titration patterns, incidence of adverse events (AEs) and associated prescribing actions. A total of 12,493 patients (68.0% male; mean age 58.0 ± SD 17.6 years) were included. Of these, 27% had discontinued beta-blockers within 1 year of initiation, increasing to 39% by 2 years and 50% by 3 years. Persistence appeared to be greater in the MI cohort compared with angina or CHF cohorts. Beta-blocker dose at initiation averaged approximately 33% of guideline recommended target, rising to 40% in those who continued with therapy. Dyspnoea, fatigue and dizziness were the most common incident AEs at 98, 53 and 49 per 1000 patient years, with little difference between indications. Conclusion A quarter of patients with cardiovascular disease who are commenced on a beta-blocker are no longer taking the drug by one year. This rises to 50% by three years, a finding that is consistent irrespective of whether the prescription is for prognostic (CHF or post MI) or symptomatic (angina) benefit. There is an urgent need to understand and address the prescribing difficulties of beta-blockers in these at-risk patients.
We describe the case of a 15-year-old girl who presented to the Accident and Emergency Department with right knee pain and a tense effusion following a twist and fall directly onto her right knee. An ...MRI scan demonstrated that she had an incarcerated dislocated patella with an associated patella avulsion fracture. This required open reduction. Open reduction and fixation was performed using suture anchors. We feel that this case is particularly pertinent since nearly all previous case reports describe an incarcerated patella with an associated femur fracture. Furthermore, no previous case reports have been published in a child.
Low Back Pain (LBP) remains a common and costly problem. Psychological obstacles to recovery have been identified, but psychological and behavioural interventions have produced only moderate ...improvements. Reviews of trials have suggested that the interventions lack clear theoretical basis, are often compromised by low dose, lack of fidelity, and delivery by non-experts. In addition, interventions do not directly target known risk mechanisms. We identified a theory driven intervention (Contexual Cognitive Behavioural Therapy, CCBT) that directly targets an evidence-based risk mechanism (avoidance and ensured dose and delivery were optimised. This feasibility study was designed to test the credibility and acceptability of optimised CCBT against physiotherapy for avoidant LBP patients, and to test recruitment, delivery of the intervention and response rates prior to moving to a full definitive trial.
A randomised controlled feasibility trial with patients randomised to receive CCBT or physiotherapy. CCBT was delivered by trained supervised psychologists on a one to one basis and comprised up to 8 one-hour sessions. Physiotherapy comprised back to fitness group exercises with at least 60 % of content exercise-based. Patients were eligible to take part if they had back pain for more than 3 months, and scored above a threshold indicating fear avoidance, catastrophic beliefs and distress.
89 patients were recruited. Uptake rates were above those predicted. Scores for credibility and acceptability of the interventions met the set criteria. Response rates at three and six months fell short of the 75 % target. Problems associated with poor response rates were identified and successfully resolved, rates increased to 77 % at 3 months, and 68 % at 6 months. Independent ratings of treatment sessions indicated that CCBT was delivered to fidelity. Numbers were too small for formal analysis. Although average scores for acceptance were higher in the CCBT group than in the group attending physiotherapy (increase of 7.9 versus 5.1) and change in disability and pain from baseline to 6 months were greater in the CCBT group than in the physiotherapy group, these findings should be interpreted with caution.
CCBT is a credible and acceptable intervention for LBP patients who exhibit psychological obstacles to recovery.
