Lying lawyers: Investigating the social cognitive label
People lie regularly and often (Vrij, 2008). However, though this is accepted, people do not like to be lied to (Epley & Huff, 2007). Because of the prevalence of the practice, people are constantly on the lookout for liars (DePaulo & Kashy, 1998). Attributions are made when a person detects a lie and then makes a decision on the person who lied (Curtis, 2016). People also hold beliefs about what liars look like. The most common cultural stereotype of lawyers is that they are liars (Michelen, 2011). The current research aimed to investigate perceptions, attributions, and attitudes of lawyers as liars and their modern-day implications. It was found that lawyers are perceived more as liars when compared to physicians. Results also showed that lawyers are not perceived to be less professional or competent. These results have implications for lawyers in todayâs society because of legal professionalsâ tendency to own a monopoly on legal knowledge and their job which requires them to âwinâ for their client at all cost (Galanter, 1998)
Outcomes in varicose vein disease
Introduction
Varicose veins are a common problem with 25-50% of the population
symptomatically affected, and chronic venous disease leads to significant
impairments in quality of life with substantial health system cost implications.
Significant variability exists in the symptoms suffered by patients, the treatment
offered and the outcomes achieved. Identification of the optimal treatment
pathways for patients remains difficult.
Aims
i. To ascertain primary care disease knowledge.
ii. To assess what affects treatment and identify which patients benefit most.
iii. To generate a predictive model of varicose vein outcomes.
iv. To assess the impact of altering treatment of varicosities in the context of
endovenous truncal vein ablation
v. To investigate the early impact of new technologies
Methods
i. Two survey studies were completed:
â 21 questions assessing venous disease management pathways was
disseminated to General Practitioners.
â 19 questions assessing the management of superficial venous
thrombosis and was distributed to General Practitioners and Vascular
Surgeons.
ii. A cohort of consecutive patients with symptomatic chronic venous disease
were assessed and completed quality of life questionnaires pre and postintervention.
iii. Uni-variable and multi-variable analysis of patient cohort data to facilitate
the creation of generalised model of venous treatment outcomes
iv. A randomised clinical trial assessing the timing of varicosity avulsion in the
context of local anaesthetic endovenous truncal ablation.
â Ambulatory Varicosity avUlsion Later or Synchronised (AVULS) trial.
v. Assessment of new technologies
â The European Sapheon Closure system Observed ProspectivE
(eSCOPE) study a multi-site cohort observational study of
cyanoacrylate glue occlusion of truncal vein incompetence
â The VNUS Versus Clarivein for Varicose Veins (VVCVV) multi-centre
randomised clinical trial comparing the procedural pain profile of
radiofrequency and mechanochemical ablation.
Results
i. Education outcomes
â 138 responses were received. The management of chronic venous
disease in the primary care setting is disparate and knowledge of
current techniques is poor, despite extensive guidance.
â 369 responses were received, from 197 vascular specialists and 172
primary care physicians. Superficial thrombophlebitis management is
shown to be diverse and does not adhere to recent evidence.
ii. 461 patients were recruited. Patients suffering from chronic venous disease
suffer from substantial quality of life impairment, including previously
under-recognised depressive symptoms. Treatment of the underlying venous
condition provides relief from venous symptoms and improves quality of life.
â Patient symptoms and quality of life do not correlate with anatomical
vein diameter, however clinical severity scores do.
iii. Predictive modelling produces models that account for 30-41% of the
variability in post-operative scores for disease specific quality of life tools,
generic quality of life tools, and clinical severity scores.
iv. The AVULS trial recruited 101 patients. Simultaneous treatment leads to
improved clinical outcomes at up to 1 year and early quality of life
improvement. Delayed treatment has a significantly increased risk of
requiring further treatment (Odds Ratio 27.78, Relative Risk 18.36,
p<0.0001). 95% of patients declining randomisation opted for simultaneous
treatment.
v. New Technology Outcomes
â The eSCOPE study recruited 70 patients in Europe with good technical
outcomes.
â The VVCVV trial (ongoing) has recruited 85 patients, with
significantly reduced procedural pain found with mechanochemical
ablation.
Conclusions
Varicose veins are a widespread problem with effective treatment that leads to a
significant improvement in quality of life. Education and communication between
community and hospital-based medicine is lacking. Predictive modelling of varicose
vein symptoms remains difficult due to the multifactorial nature of the disease.
Simultaneous treatment of varicosities during endovenous truncal ablation
produces improved outcomes and is the option of choice for most patients. Early
data on new technologies show they provide less painful procedures with similar
outcomes as the established modalities.Open Acces
Priority list of endemic diseases for the red meat industries
This report provides a systematic review of the most economically damaging endemic diseases and conditions for the Australian red meat industry (cattle, sheep and goats). A number of diseases for cattle, sheep and goats have been identified and were prioritised according to their prevalence, distribution, risk factors and mitigation. The economic cost of each disease as a result of production losses, preventive costs and treatment costs is estimated at the herd and flock level, then extrapolated to a national basis using herd/flock demographics from the 2010-11 Agricultural Census by the Australian Bureau of Statistics. Information shortfalls and recommendations for further research are also specified.
A total of 17 cattle, 23 sheep and nine goat diseases were prioritised based on feedback received from producer, government and industry surveys, followed by discussions between the consultants and MLA. Assumptions of disease distribution, in-herd/flock prevalence, impacts on mortality/production and costs for prevention and treatment were obtained from the literature where available. Where these data were not available, the consultants used their own expertise to estimate the relevant measures for each disease. Levels of confidence in the assumptions for each disease were estimated, and gaps in knowledge identified.
The assumptions were analysed using a specialised Excel model that estimated the per animal, herd/flock and national costs of each important disease. The report was peer reviewed and workshopped by the consultants and experts selected by MLA before being finalised. Consequently, this report is an important resource that will guide and prioritise future research, development and extension activities by a variety of stakeholders in the red meat industry. This report completes Phase I and Phase II of an overall four-Phase project initiative by MLA, with identified data gaps in this report potentially being addressed within the later phases.
Modelling the economic costs using a consistent approach for each disease ensures that the derived estimates are transparent and can be refined if improved data on prevalence becomes available. This means that the report will be an enduring resource for developing policies and strategies for the management of endemic diseases within the Australian red meat industry
Chemical composition and quality loss during technological treatment in coho salmon (Oncorhynchus kisutch)
Coho salmon (Oncorhynchus kisutch) supports an important farming production
in parallel with capture delivery, giving rise to products of great economic importance
in many countries. This review covers the research carried out during the last decades
related to its employment as a food product. In a first part, studies carried out
concerning the chemical constituent composition and nutritional value are reviewed; a
special attention is accorded to the wild/ farmed fish comparison and to the effect of diet
on lipid composition variations. In agreement to the great lability of chemical
constituents of aquatic foods, the second part of the manuscript provides a revision of
coho salmon research related to the chemical component changes produced during
technological processing and their effects on nutritional and sensory losses; in this case,
a special attention is accorded to studies employing advanced technological strategies
focused to partially inhibit the development of the different damage pathways.support provided by the Universidad de Chile (Chile)-

A randomised controlled trial of neuromuscular stimulation in non-operative venous disease improves clinical and symptomatic status.
Funder: Actergy HealthBACKGROUND: This randomised controlled trial investigates the dosing effect of neuromuscular electrical stimulation (NMES) in patients with chronic venous disease (CVD). METHODS: Seventy-six patients with CEAP C3-C5 were randomised to Group A (no NMES), B (30 minutes of NMES daily) or C (60 minutes of NMES daily). Primary outcome was percentage change in Femoral Vein Time Averaged Mean Velocity (TAMV) at 6 weeks. Clinical severity scores, disease-specific and generic quality of life (QoL) were assessed. RESULTS: Seventy-six patients were recruited - mean age 60.8 (SD14.4) and 47:29 male. Six patients lost to follow-up. Percentage change in TAMV (p<0.001) was significantly increased in Groups B and C. Aberdeen Varicose Veins Questionnaire Score (-6.9, p=0.029) and Venous Clinical Severity Score (-4, p-0.003) improved in Group C, and worsened in Group A (+1, p=0.025). CONCLUSIONS: Daily NMES usage increases flow parameters, with twice daily usage improving QoL and clinical severity at 6 weeks in CVD patients
Abdominal aortic aneurysm clinical practice guidelines: a methodological assessment using the AGREE II instrument.
OBJECTIVES: Abdominal aortic aneurysm (AAA) clinical practice guidelines (CPGs) provide evidence-based information on patient management; however, methodological differences exist in the development of CPGs. This study examines the methodological quality of AAA CPGs using a validated assessment tool. METHODS: Medline, EMBASE and online CPG databases were searched from 1946 to 31 October 2021. Full-text, English language, evidence-based AAA CPGs were included. Consensus-based CPGs, summaries of CPGs or CPGs which were only available on purchase were excluded. Five reviewers assessed their quality using the Appraisal of Guidelines for Research and Evaluation II instrument. An overall guideline assessment scaled score of â„80% was considered as the threshold to recommend CPG use in clinical practice. RESULTS: Seven CPGs were identified. Scores showed good inter-reviewer reliability (intraclass correlation coefficient 0.943, 95%âCI 0.915 to 0.964). On average, CPGs performed adequately with mean scaled scores of over 50% in all domains. However, between CPGs, significant methodological heterogeneity was observed in all domains. Four CPGs scored â„80% (European Society of Cardiology, the Society of Vascular Surgery, the European Society of Vascular Surgery and the National Institute of Health and Care Excellence), supporting their use in clinical practice. CONCLUSIONS: Four CPGs were considered of adequate methodological quality to recommend their use in clinical practice; nonetheless, these still showed areas for improvement, potentially through performing economic analysis and trial application of recommendations. A structured approach employing validated CPG creation tools should be used to improve rigour of AAA CPGs. Future work should also evaluate recommendation accuracy using validated appraisal tools
Low intrinsic efficacy for G protein activation can explain the improved side-effect profile of new opioid agonists
Biased agonism at G proteinâcoupled receptors describes the phenomenon whereby some drugs can activate some downstream signaling activities to the relative exclusion of others. Descriptions of biased agonism focusing on the differential engagement of G proteins versus ÎČ-arrestins are commonly limited by the small response windows obtained in pathways that are not amplified or are less effectively coupled to receptor engagement, such as ÎČ-arrestin recruitment. At the ÎŒ-opioid receptor (MOR), G proteinâbiased ligands have been proposed to induce less constipation and respiratory depressant side effects than opioids commonly used to treat pain. However, it is unclear whether these improved safety profiles are due to a reduction in ÎČ-arrestinâmediated signaling or, alternatively, to their low intrinsic efficacy in all signaling pathways. Here, we systematically evaluated the most recent and promising MOR-biased ligands and assessed their pharmacological profile against existing opioid analgesics in assays not confounded by limited signal windows. We found that oliceridine, PZM21, and SR-17018 had low intrinsic efficacy. We also demonstrated a strong correlation between measures of efficacy for receptor activation, G protein coupling, and ÎČ-arrestin recruitment for all tested ligands. By measuring the antinociceptive and respiratory depressant effects of these ligands, we showed that the low intrinsic efficacy of opioid ligands can explain an improved side effect profile. Our results suggest a possible alternative mechanism underlying the improved therapeutic windows described for new opioid ligands, which should be taken into account for future descriptions of ligand action at this important therapeutic target
The Chlamydia effector TarP mimics the mammalian leucine-aspartic acid motif of paxillin to subvert the focal adhesion kinase during invasion
Host cell signal transduction pathways are often targets of bacterial pathogens, especially during the process of invasion when robust actin remodeling is required. We demonstrate that the host cell focal adhesion kinase (FAK) was necessary for the invasion by the obligate intracellular pathogen Chlamydia caviae. Bacterial adhesion triggered the transient recruitment of FAK to the plasma membrane to mediate a Cdc42- and Arp2/3-dependent actin assembly. FAK recruitment was via binding to a domain within the virulence factor TarP that mimicked the LD2 motif of the FAK binding partner paxillin. Importantly, bacterial two-hybrid and quantitative imaging assays revealed a similar level of interaction between paxillin-LD2 and TarP-LD. The conserved leucine residues within the L(D/E)XLLXXL motif were essential to the recruitment of FAK, Cdc42, p34Arc, and actin to the plasma membrane. In the absence of FAK, TarP-LD-mediated F-actin assembly was reduced, highlighting the functional relevance of this interaction. Together, the data indicate that a prokaryotic version of the paxillin LD2 domain targets the FAK signaling pathway, with TarP representing the first example of an LD-containing Type III virulence effector
The Long-Baseline Neutrino Experiment: Exploring Fundamental Symmetries of the Universe
The preponderance of matter over antimatter in the early Universe, the
dynamics of the supernova bursts that produced the heavy elements necessary for
life and whether protons eventually decay --- these mysteries at the forefront
of particle physics and astrophysics are key to understanding the early
evolution of our Universe, its current state and its eventual fate. The
Long-Baseline Neutrino Experiment (LBNE) represents an extensively developed
plan for a world-class experiment dedicated to addressing these questions. LBNE
is conceived around three central components: (1) a new, high-intensity
neutrino source generated from a megawatt-class proton accelerator at Fermi
National Accelerator Laboratory, (2) a near neutrino detector just downstream
of the source, and (3) a massive liquid argon time-projection chamber deployed
as a far detector deep underground at the Sanford Underground Research
Facility. This facility, located at the site of the former Homestake Mine in
Lead, South Dakota, is approximately 1,300 km from the neutrino source at
Fermilab -- a distance (baseline) that delivers optimal sensitivity to neutrino
charge-parity symmetry violation and mass ordering effects. This ambitious yet
cost-effective design incorporates scalability and flexibility and can
accommodate a variety of upgrades and contributions. With its exceptional
combination of experimental configuration, technical capabilities, and
potential for transformative discoveries, LBNE promises to be a vital facility
for the field of particle physics worldwide, providing physicists from around
the globe with opportunities to collaborate in a twenty to thirty year program
of exciting science. In this document we provide a comprehensive overview of
LBNE's scientific objectives, its place in the landscape of neutrino physics
worldwide, the technologies it will incorporate and the capabilities it will
possess.Comment: Major update of previous version. This is the reference document for
LBNE science program and current status. Chapters 1, 3, and 9 provide a
comprehensive overview of LBNE's scientific objectives, its place in the
landscape of neutrino physics worldwide, the technologies it will incorporate
and the capabilities it will possess. 288 pages, 116 figure
