Development and validation of a questionnaire to assess owner and canine quality-of-life and treatment satisfaction in canine allergic dermatitis

BACKGROUND

Animal and owner quality-of-life (QoL) is pivotal in treatment decisions. Accurate measurement of owner-reported QoL and treatment satisfaction (TS) supports disease burden and treatment benefit evaluation.

OBJECTIVES

Develop and evaluate an owner-completed canine dermatitis QoL and TS questionnaire (CDQoL-TSQ) in allergic dogs.

MATERIALS AND METHODS

The CDQoL-TSQ was drafted following review of existing measures and expert input. Content validity was assessed through interviews with owners of allergic dogs. Psychometric properties of the QoL domains (Canine QoL, Owner QoL) were evaluated. Score interpretation was derived.

RESULTS

Twenty dog owners were interviewed. Item wording was amended following the first 10 interviews. Data from 211 owners were used in the psychometric evaluation. The Canine QoL domain demonstrated strong internal consistency (α = 0.89), test-retest reliability (ICC2,1  = 0.844), moderate convergent validity (r = 0.41) and moderate-high known-groups validity (effect size 0.37-0.64). The Owner QoL domain demonstrated strong internal consistency (α = 0.73), high convergent validity (r = 0.63) and moderate-high known-groups validity (0.43-0.63). Test-retest reliability approached moderate strength (ICC2,1  = 0.490). Group-level interpretation analysis showed minimal important difference of 7.0-13.6 points for dogs and 13.0-13.6 for owners. For individual dogs a change of 6.3 or 12.5 points for dogs, and 12.5 or 18.8 for owners indicates a response.

CONCLUSIONS AND CLINICAL RELEVANCE

The CDQOL-TSQ is a two-part assessment to evaluate QoL and TS in canine allergic dermatitis. The QoL questionnaire demonstrated validity and reliability, and interpretation of scores was derived, making it suitable for use in research and practice. The TS module is suitable for clinical setting use to improve owner-veterinarian communication.

Medicalisation of vaping in the UK? E-cigarette users' perspectives on the merging of commercial and medical routes to vaping

BACKGROUND

In the UK, most smokers choosing e-cigarettes to quit smoking will access vaping via commercial routes. In recent years, however, a shift towards medicalisation of vaping has become apparent, with public health guidance supporting e-cigarettes for smoking cessation and increased partnership working between healthcare professionals and the vaping industry. To achieve the UK's Smokefree 2030 target, the UK Government has set out measures to use e-cigarettes in National Health Service (NHS) settings and to move towards streamlining processes to make e-cigarettes available to a million smokers. This article aims to understand acceptability of different approaches by seeking perspectives of people with lived experience of e-cigarette use for smoking cessation.

METHODS

Mixed methods data collected between March 2018 and March 2019 as part of a broader study of e-cigarette use trajectories (ECtra study). Data here relate to the views of partnership working and medicalisation of vaping extracted from 136 interviews/extended surveys of people who had used e-cigarettes to try to stop smoking. Qualitative data were thematically analysed. Participant ratings of interventions were presented descriptively, and differences in participant characteristics and ratings were reported.

RESULTS

Three qualitative themes were identified: pro-partnership, anti-partnership and medicalisation dissonance. Medicalisation was discussed for its potential to reassure smokers about e-cigarette harms and its potential to reach smokers from disadvantaged backgrounds. Concerns were raised about cost-effectiveness, quality of support, conflicts of interest and limiting product choice. Most participants rated interventions involving partnership working as potentially helpful in switching from smoking to vaping. There were no statistically significant associations between age, gender and socioeconomic status, and helpfulness ratings.

CONCLUSION

Both commercial and medical routes to vaping offer perceived benefits to vapers and may complement and reinforce each other to support smoking cessation.

Using a Consensus-Driven Approach to Incorporate Holistic Review Into an Internal Medicine Residency Program

Background

Despite growing interest in incorporating holistic review within residency admissions, implementation by residency programs remains challenging.

Objective

To incorporate holistic review into the internal medicine residency program at the University of Wisconsin and to report initial feasibility and acceptability data.

Methods

During the 2020-2021 application cycle, residency stakeholders performed a consensus-driven process to identify highly valued applicant attributes. We used a holistic review process to identify the presence of these attributes among applicants and updated our rank list algorithm to incorporate these attributes. We modified our interview screening criteria and rank list algorithm to de-emphasize other metrics. We surveyed stakeholders to assess time required for this process and compared our final rank list to what it would have been using our prior system.

Results

The final list of 10 prioritized applicant attributes included extraordinary leadership, community service, and grit, among others. Among 25 matched residents, 8 (32%) were recognized to have exceptional achievement within one of these 10 attributes. Four members of the incoming intern class (16%) would have been in a rank position lower than our historical matched resident cutoff had they not received additional points for these attributes. Faculty reported that holistic review of applications took an additional 3.8 minutes on average. It was felt that current application materials limit the ability to implement a fully holistic review.

Conclusions

The addition of holistic review to our residency admissions process was achieved using a consensus-driven approach and showed favorable feasibility and acceptability data.

Higher Incidence of Unruptured Intracranial Aneurysms among Black and Hispanic Women on Screening MRA in Large Urban Populations

BACKGROUND AND PURPOSE

Intracranial aneurysms have a reported prevalence of 1%-2% in the general population. Currently, only patients with a strong family history or autosomal dominant polycystic kidney disease are screened for intracranial aneurysms using MRA. The purpose of this study was to determine whether there are other specific patient populations at risk that should be offered screening for intracranial aneurysms.

MATERIALS AND METHODS

This is a retrospective case-control study of adult patients who underwent a screening MRA of their brain at our comprehensive stroke center from 2011 to 2020. Patients with a history of a known brain aneurysm were excluded. Data were extracted on patient demographics and medical comorbidities. Bivariate analyses were performed, followed by multivariable logistic regression, to identify factors associated with a positive MRA screen for incidental aneurysms.

RESULTS

Of 24,397 patients eligible for this study, 2084 screened positive for a possible intracranial aneurysm. On bivariate analysis, significant differences were present in the following categories: age, sex, race and ethnicity, chronic constipation, and hyperlipidemia. On logistic regression analysis, older age (+10 years: OR = 10.01; 95% CI, 10.01-10.02; P = .001), female sex (OR = 1.37; 95% CI, 1.24-1.51; P = .001), non-Hispanic Black (OR = 1.19; 95% CI, 1.02-1.40; P = .031), and Hispanic ethnicity (OR = 1.35; 95% CI, 1.16-1.58; P = .001) versus non-Hispanic White remained significant when adjusted for other factors.

CONCLUSIONS

Targeted screening for high-risk elderly women of Black or Hispanic descent will yield higher positive findings for brain aneurysms, which may mitigate the risk of rupture. Whether this is a cost-effective approach has yet to be determined.

Randomised controlled trial of the short-term effects of osmotic-release oral system methylphenidate on symptoms and behavioural outcomes in young male prisoners with attention deficit hyperactivity disorder: CIAO-II study

BACKGROUND

Research has shown that 20-30% of prisoners meet the diagnostic criteria for attention-deficit hyperactivity disorder (ADHD). Methylphenidate reduces ADHD symptoms, but effects in prisoners are uncertain because of comorbid mental health and substance use disorders.

AIMS

To estimate the efficacy of an osmotic-release oral system methylphenidate (OROS-methylphenidate) in reducing ADHD symptoms in young adult prisoners with ADHD.

METHOD

We conducted an 8-week parallel-arm, double-blind, randomised placebo-controlled trial of OROS-methylphenidate versus placebo in male prisoners (aged 16-25 years) meeting the DSM-5 criteria for ADHD. Primary outcome was ADHD symptoms at 8 weeks, using the investigator-rated Connors Adult ADHD Rating Scale (CAARS-O). Thirteen secondary outcomes were measured, including emotional dysregulation, mind wandering, violent attitudes, mental health symptoms, and prison officer and educational staff ratings of behaviour and aggression.

RESULTS

In the OROS-methylphenidate arm, mean CAARS-O score at 8 weeks was estimated to be reduced by 0.57 points relative to the placebo arm (95% CI -2.41 to 3.56), and non-significant. The responder rate, defined as a 20% reduction in CAARS-O score, was 48.3% for the OROS-methylphenidate arm and 47.9% for the placebo arm. No statistically significant trial arm differences were detected for any of the secondary outcomes. Mean final titrated dose was 53.8 mg in the OROS-methylphenidate arm.

CONCLUSIONS

ADHD symptoms did not respond to OROS-methylphenidate in young adult prisoners. The findings do not support routine treatment with OROS-methylphenidate in this population. Further research is needed to evaluate effects of higher average dosing and adherence to treatment, multi-modal treatments and preventative interventions in the community.

Evaluation of a training programme for Pharmacist Independent Prescribers in a care home medicine management intervention

BACKGROUND

The provision of independent prescribing rights for United Kingdom (UK) pharmacists has enabled them to prescribe within their area of competence. The aim of this study was to evaluate an evidence-based training programme designed to prepare Pharmacist Independent Prescribers (PIPs) to safely and effectively assume responsibility for pharmaceutical care of older people in care homes in the UK, within a randomised controlled trial.

METHODS

The training and competency assessment process included two training days, professional development planning against a bespoke competency framework, mentor support, and a viva with an independent General Practitioner (GP). Data on the PIPs' perceptions of the training were collected through evaluation forms immediately after the training days and through online questionnaires and interviews after delivery of the 6-month intervention. Using a mixed method approach each data set was analysed separately then triangulated providing a detailed evaluation of the process. Kaufman's Model of Learning Evaluation guided interpretations.

RESULTS

All 25 PIPs who received the training completed an evaluation form (N = 25). Post-intervention questionnaires were completed by 16 PIPs and 14 PIPs took part in interviews. PIPs reported the training days and mentorship enabled them to develop a personalised portfolio of competence in preparation for discussion during a viva with an independent GP. Contact with the mentor reduced as PIPs gained confidence in their role. PIPs applied their new learning throughout the delivery of the intervention leading to perceived improvements in residents' quality of life and medicines management. A few PIPs reported that developing a portfolio of competence was time intensive, and that further training on leadership skills would have been beneficial.

CONCLUSIONS

The bespoke training programme was fit for purpose. Mentorship and competency assessment were resource intensive but appropriate. An additional benefit was that many PIPs reported professional growth beyond the requirement of the study.

TRIAL REGISTRATION

The definitive RCT was registered with the ISRCTN registry (registration number ISRCTN 17,847,169 ).

Randomized, double-blind, placebo-controlled trial of ISC 17536, an oral inhibitor of transient receptor potential ankyrin 1, in patients with painful diabetic peripheral neuropathy: impact of preserved small nerve fiber function

ABSTRACT

Patients with chronic pain syndromes, such as those with painful peripheral neuropathy due to diabetes mellitus, have limited treatment options and suffer ongoing attrition of their quality of life. Safer and more effective treatment options are needed. One therapeutic approach encompasses phenotypic characterization of the neuropathic pain subtype, combined with the selection of agents that act on relevant mechanisms. ISC 17536 is a novel, orally available inhibitor of the widely expressed pain receptor, transient receptor potential ankyrin 1, which mediates nociceptive signaling in peripheral small nerve fibers. In this randomized, placebo-controlled, proof-of-concept trial, we assessed the safety and efficacy of 28-day administration of ISC 17536 in 138 patients with chronic, painful diabetic peripheral neuropathy and used quantitative sensory testing to characterize the baseline phenotype of patients. The primary end point was the change from baseline to end of treatment in the mean 24-hour average pain intensity score based on an 11-point pain intensity numeric rating scale. The study did not meet the primary end point in the overall patient population. However, statistically significant and clinically meaningful improvement in pain were seen with ISC 17536 in an exploratory hypothesis-generating subpopulation of patients with preserved small nerve fiber function defined by quantitative sensory testing. These results may provide a mechanistic basis for targeted therapy in specific pain phenotypes in line with current approaches of "precision medicine" or personalized pain therapeutics. The hypothesis is planned to be tested in a larger phase 2 study.

The Effect of Overexpression of Lrp5 on the Temporomandibular Joint

OBJECTIVE

The temporomandibular joint (TMJ) is a unique fibrocartilaginous joint that adapts to mechanical loading through cell signaling pathways such as the Wnt pathway. Increased expression of low-density lipoprotein receptor-related protein 5 (Lrp5), a co-receptor of the Wnt pathway, is associated with a high bone mass (HBM) phenotype. The objective of this study was to analyze the effect of overexpression of Lrp5 on the subchondral bone and cartilage of the TMJ in mice exhibiting the HBM phenotype.

DESIGN

Sixteen-week-old Lrp5 knock-in transgenic mice carrying either the A214V (EXP-A) or G171V (EXP-G) missense mutations, and wildtype controls (CTRL) were included in this study. Fluorescent bone labels, calcein, alizarin complexone, and demeclocycline were injected at 3.5, 7.5, and 11.5 weeks of age, respectively. The left mandibular condyle was used to compare the subchondral bone micro-computed tomography parameters and the right TMJ was used for histological analyses. Cartilage thickness, matrix proteoglycan accumulation, and immunohistochemical localization of Lrp5 and sclerostin were compared between the groups.

RESULTS

Subchondral bone volume (BV) and percent bone volume (BV/TV) were significantly increased in both EXP-A and EXP-G compared with CTRL (P < 0.05) whereas trabecular spacing (Tb.Sp) was decreased. Cartilage thickness, extracellular matrix production, and expression of Lrp5 and Sost were all increased in the experimental groups. The separation between the fluorescent bone labels indicated increased endochondral maturation between 3.5 and 7.5 weeks.

CONCLUSIONS

These data demonstrate that Lrp5 overexpression leads to adaptation changes in the mandibular condylar cartilage of the TMJ to prevent cartilage degradation.

Effects of Soybean Cultivar, Foliar Application of Azoxystrobin, and Year on Seed Vigor and Microflora Under Delayed Harvest Conditions

The effects of cultivar and foliar fungicide applications on soybean seed germination, vigor, microflora, and yield after delayed harvest were determined at the University of Arkansas Vegetable Research Station in Kibler, AR, from 2008 to 2010. Seven cultivars with varying levels of resistance to Diaporthe spp. or Cercospora spp. were treated or not treated with a foliar application of azoxystrobin at the R5 growth stage. Plots were harvested 3 weeks after the plants had reached harvest maturity. Yields were recorded, samples of seed were collected, and standard germination (SG) and accelerated aging (AA) were assessed. Seeds were also assayed for infection by fungi on modified potato dextrose agar and by bacteria on nutrient agar. Seed vigor was significantly reduced by infection with Diaporthe spp., Fusarium spp., and Bacillus subtilis, but not with Cercospora spp. Cultivar had a significant impact on yield, seed vigor, and seed infection levels. The cultivar Osage had consistently high seed vigor and low overall seed infection incidence throughout the study. MO/PSD-0259, AG 4403, and UA 4805 also had relatively high seed vigor and low seed infection rates. PI 80837 had a low incidence of seed infection by Diaporthe spp. and Fusarium spp. in 2008 and 2010, but high levels in 2009, when environmental conditions were especially favorable for these pathogens. AP 350 and Suweon97 had relatively high seed infection incidences, particularly of Diaporthe spp. and Fusarium spp., and relatively low seed vigor. Application of the foliar fungicide azoxystrobin at the R5 growth stage significantly increased AA across years and cultivars and increased seed infection by Diaporthe spp. in 2009 across cultivars. There were significant negative correlations between yield and seed infection by Diaporthe spp. and Bacillus subtilis during 1 year and with Fusarium spp. during all 3 years. Overall, resistance to seed infection can persist even when harvest is delayed. In addition to Diaporthe spp., other seedborne pathogens may reduce seed vigor and yield.

The effect of overexpression of Lrp5 on orthodontic tooth movement

OBJECTIVE

To analyse the effect of gain-of-function mutations in the low-density lipoprotein receptor-related protein 5 (Lrp5) on orthodontic tooth movement (OTM).

SETTING AND SAMPLE POPULATION

A split-mouth study design was utilized. Thirty-two male Lrp5-high bone mass (HBM) knock-in mice including A214V and G171V mutants (n = 16/group) and sixteen C57BL/6 wild-type (WT) mice were included in the study.

MATERIALS AND METHODS

A mouse model of OTM was used for mesial movement of the maxillary first molar using a closed-coil nickel titanium (NiTi) spring attached between the molar and the incisors. After 21 days, the dissected maxillae were scanned for micro-computed tomography (micro-CT) analyses and embedded in methyl methacrylate and paraffin for histological staining and imaging. Histological analyses included immunohistochemistry for sclerostin (Sost), tartrate-resistant acid phosphatase (TRAP) staining for osteoclasts and fluorescent imaging.

RESULTS

OTM in the A214V and G171V groups was significantly less than the WT group. Bone volume (BV), per cent bone volume (BV/TV) and trabecular thickness (Tb.Th) were significantly increased in both A241V and G171V animals compared to the WT animals. On the compression side, decreased osteoclast activity was seen in both A214V and G171V groups compared to the WT group. Fluorescent labelling demonstrated that the pattern of bone deposition in the A214V animals was periosteal whereas the G171V animals added bone endocortically.

CONCLUSION

Gain-of-function mutations of Lrp5 decrease orthodontic tooth movement by increasing alveolar bone mass and reducing osteoclast-mediated bone resorption.

Long-term cost-effectiveness of screening for fracture risk in a UK primary care setting: the SCOOP study

Community-based screening and treatment of women aged 70-85 years at high fracture risk reduced fractures; moreover, the screening programme was cost-saving. The results support a case for a screening programme of fracture risk in older women in the UK.

INTRODUCTION

The SCOOP (screening for prevention of fractures in older women) randomized controlled trial investigated whether community-based screening could reduce fractures in women aged 70-85 years. The objective of this study was to estimate the long-term cost-effectiveness of screening for fracture risk in a UK primary care setting compared with usual management, based on the SCOOP study.

METHODS

A health economic Markov model was used to predict the life-time consequences in terms of costs and quality of life of the screening programme compared with the control arm. The model was populated with costs related to drugs, administration and screening intervention derived from the SCOOP study. Fracture risk reduction in the screening arm compared with the usual management arm was derived from SCOOP. Modelled fracture risk corresponded to the risk observed in SCOOP.

RESULTS

Screening of 1000 patients saved 9 hip fractures and 20 non-hip fractures over the remaining lifetime (mean 14 years) compared with usual management. In total, the screening arm saved costs (£286) and gained 0.015 QALYs/patient in comparison with usual management arm.

CONCLUSIONS

This analysis suggests that a screening programme of fracture risk in older women in the UK would gain quality of life and life years, and reduce fracture costs to more than offset the cost of running the programme.

AB0737 MEASUREMENT PROPERTIES OF RADIOGRAPHIC OUTCOME MEASURES IN PSORIATIC ARTHRITIS: A SYSTEMATIC REVIEW FROM THE GRAPPA-OMERACT INITIATIVE

Background:

Structural damage was identified as an important outcome domain in the Psoriatic Arthritis (PsA) Core Domain Set and should be assessed at least once in the development of a new therapeutic.

Objectives:

To conduct a systematic literature review (SLR) to identify studies addressing the measurement properties (MPs) for ROIs and appraise the evidence through the OMERACT Filter 2.1 Framework Instrument Selection Algorithm (OFISA). [1]

Methods:

An SLR was conducted in EMBASE and MEDLINE to identify full-text English studies developing or assessing MPs of ROIs in PsA. Determination of eligibility, data extraction and methodology asssessment were performed by 2 reviewers. MPs were rated according to the ‘Provisional Standards’ and assigned a Red/Amber/White/Green (RAWG) rating (Figure 1). [1, 2]

Results:

3621 references were screened, 531 full-text articles reviewed, and 12 were included (Figure 2). Nine instruments assessing peripheral radiographs and six assessing axial radiographs were identified (Table 1). Three of the nine peripheral radiographic instruments had adequate evidence for reliability and some evidence for construct validity: the modified Steinbrocker, Ratingen, and modified Sharp van der Heijde scores. There was scant evidence for reliability, construct validity and responsiveness for the axial ROIs, compounded by the lack of a standardized definition of axial PsA.

Conclusion:

This SLR summarizes the MPs of ROIs and identifies relevant knowledge gaps that need to be addressed prior to endorsement of an instrument for the PsA Core Domain Set.

AB0794 CLINICAL TRIAL DISCRIMINATION OF PHYSICAL FUNCTION INSTRUMENTS FOR PSORIATIC ARTHRITIS: A SYSTEMATIC REVIEW

Background:

Physical function is a core domain to be measured in randomized controlled trials (RCTs) of psoriatic arthritis (PsA). The discriminative performance of patient reported outcome measures (PROMs) for physical function (PF) in RCTs has not been evaluated systematically.

Objectives:

In this systematic review, the GRAPPA-OMERACT working group aimed to evaluate the clinical trial discrimination of PF-PROMs in PsA RCTs.

Methods:

We searched PubMed and Scopus databases in English to identify all original RCTs conducted in PsA. We limited the review to RCTs of biologic and targeted synthetic DMARDs. Groups of two researchers extracted data independently for PF-PROMs. We assessed quality in each article using the OMERACT good method checklist. Effect sizes (ES) for the PF-PROMs were calculated and appraised usinga priorihypotheses. Evidence supporting clinical trial discrimination for each PF-PROM was summarized to derive recommendations.

Results:

32 articles were included (Figure 1). Four PF-PROMs had data for evaluation: HAQ-Disability Index (DI), HAQ-Spondyloarthritis (S), Short Form 36-item Health Survey Physical Component Summary (SF-36 PCS), and the Physical Functioning domain (SF-36 PF) (Table 1). The ES for intervention versus (vs.) control arms for HAQ-DI ranged from -0.55 to -1.81 vs. 0.24 to -0.52; and for SF-36 PCS ranged from 0.30 to 1.86 vs. -0.02 to 0.63.

Screening for high hip fracture risk does not impact on falls risk: a post hoc analysis from the SCOOP study

A reduction in hip fracture incidence following population screening might reflect the effectiveness of anti-osteoporosis therapy, behaviour change to reduce falls, or both. This post hoc analysis demonstrates that identifying high hip fracture risk by FRAX was not associated with any alteration in falls risk.

INTRODUCTION

To investigate whether effectiveness of an osteoporosis screening programme to reduce hip fractures was mediated by modification of falls risk in the screening arm.

METHODS

The SCOOP study recruited 12,483 women aged 70-85 years, individually randomised to a control (n = 6250) or screening (n = 6233) arm; in the latter, osteoporosis treatment was recommended to women at high risk of hip fracture, while the control arm received usual care. Falls were captured by self-reported questionnaire. We determined the influence of baseline risk factors on future falls, and then examined for differences in falls risk between the randomisation groups, particularly in those at high fracture risk.

RESULTS

Women sustaining one or more falls were slightly older at baseline than those remaining falls free during follow-up (mean difference 0.70 years, 95%CI 0.55-0.85, p < 0.001). A higher FRAX 10-year probability of hip fracture was associated with increased likelihood of falling, with fall risk increasing by 1-2% for every 1% increase in hip fracture probability. However, falls risk factors were well balanced between the study arms and, importantly, there was no evidence of a difference in falls occurrence. In particular, there was no evidence of interaction (p = 0.18) between baseline FRAX hip fracture probabilities and falls risk in the two arms, consistent with no impact of screening on falls in women informed to be at high risk of hip fracture.

CONCLUSION

Effectiveness of screening for high FRAX hip fracture probability to reduce hip fracture risk was not mediated by a reduction in falls.

Systematic screening using FRAX® leads to increased use of, and adherence to, anti-osteoporosis medications: an analysis of the UK SCOOP trial

In the large community-based SCOOP trial, systematic fracture risk screening using FRAX^® led to greater use of AOM and greater adherence, in women at high fracture risk, compared with usual care.

INTRODUCTION

In the SCreening of Older wOmen for Prevention of fracture (SCOOP) trial, we investigated the effect of the screening intervention on subsequent long-term self-reported adherence to anti-osteoporosis medications (AOM).

METHODS

SCOOP was a primary care-based UK multicentre trial of screening for fracture risk. A total of 12,483 women (70-85 years) were randomised to either usual NHS care, or assessment using the FRAX^® tool ± dual-energy X-ray absorptiometry (DXA), with medication recommended for those found to be at high risk of hip fracture. Self-reported AOM use was obtained by postal questionnaires at 6, 12, 24, 36, 48 and 60 months. Analysis was limited to those who initiated AOM during follow-up. Logistic regression was used to explore baseline determinants of adherence (good ≥ 80%; poor < 80%).

RESULTS

The mean (SD) age of participants was 75.6 (4.2) years, with 6233 randomised to screening and 6250 to the control group. Of those participants identified at high fracture risk in the screening group, 38.2% of those on treatment at 6 months were still treated at 60 months, whereas the corresponding figure for the control group was 21.6%. Older age was associated with poorer adherence (OR per year increase in age 0.96 [95% CI 0.93, 0.99], p = 0.01), whereas history of parental hip fracture was associated with greater rate adherence (OR 1.67 [95% CI 1.23, 2.26], p < 0.01).

CONCLUSIONS

Systematic fracture risk screening using FRAX^® leads to greater use of AOM and greater adherence, in women at high fracture risk, compared with usual care.

Comparison of the Reveal 20-Hour Method and the BAM Culture Method for the Detection of Escherichia coli O157:H7 in Selected Foods and Environmental Swabs: Collaborative Study

Four different food types along with environmental swabs were analyzed by the Reveal for E. coli O157:H7 test (Reveal) and the Bacteriological Analytical Manual (BAM) culture method for the presence of Escherichia coli O157:H7. Twenty-seven laboratories representing academia and private industry in the United States and Canada participated. Sample types were inoculated with E. coli O157:H7 at 2 different levels. Of the 1095 samples and controls analyzed and confirmed, 459 were positive and 557 were negative by both methods. No statistical differences (p &lt;0.05) were observed between the Reveal and BAM methods.

Reveal 8-Hour Test System for Detection of Escherichia coli O157:H7 in Raw Ground Beef, Raw Beef Cubes, and Iceberg Lettuce Rinse: Collaborative Study

Five different food types were analyzed by the Reveal for E. coli O157:H7 8-Hour Test System (Reveal 8) and either the U.S. Food and Drug Administration's Bacteriological Analytical Manual (BAM) culture method or the U.S. Department of Agriculture Food Safety Inspection Service (FSIS) culture method for the presence of E. coli O157:H7. A total of 27 laboratories representing academia and private industry in the United States and Canada participated. Food types were inoculated with E. coli O157:H7 at 2 different levels: a high level where predominantly positive results were expected, and a low level where fractional recovery was anticipated. During this study, 1110 samples and controls were analyzed by both the Reveal 8 and by BAM or FSIS by each of the collaborators (2220 samples in total). For each set of samples, 740 were artificially inoculated with E. coli O157:H7, and 370 were uninoculated controls. The Reveal 8 detected 528 presumptive positives of which 487 were confirmed positive by the BAM culture method. In comparison, BAM and FSIS detected 489 of the 740 artificially contaminated samples as positive. In an additional in-house study performed only on chilled and frozen raw ground beef, 240 artificially inoculated samples were analyzed by both the Reveal 8 and by FSIS. The Reveal 8 detected and confirmed 104 samples as positive compared to 79 confirmed positive by FSIS.

Hubert Ingham Clements: A Pioneer of Australian Anaesthesia

Hubert Ingham Clements was an inventor, designer and engineer who manufactured many pieces of apparatus for use in the scientific and medical practice, particularly in the field of anaesthesia from 1917 when he designed and manufactured suction pumps and anaesthetic machines.

His products were ingenious, light and portable where desirable, but sturdy, extraordinarily reliable, of low maintenance and high performance. His contribution to the specialty of anaesthesia is acknowledged.

Decline and Fall—a Tragedy in Three Acts

Pre World War II, practising anaesthetists in Australia relied heavily on two companies—Commonwealth Industrial Gases and H.I. Clements & Son—for technical support. Post-war, these two were joined by Telectronics, the Australian company which exploited the electronic revolution in monitoring. From a position of profitability and major market share, all three fell to earth for commercial, political and managerial reasons.

Analyzing Spatial Learning and Prosocial Behavior in Mice Using the Barnes Maze and Damsel-in-Distress Paradigms

The Barnes maze is a reliable measure of spatial learning and memory that does not require food restriction or exposure to extremely stressful stimuli. The Barnes maze can also assess other mouse behaviors, such as general motivation to escape from the maze platform and exploratory behavior. The Barnes maze can measure whether a genetic mutation or environmental variable can impact the acquisition and retention of spatial memories, as well as provide information about the search strategy employed by the mice. Here we use the Barnes maze to detect a memory deficit in adult mice following a single developmental ethanol exposure event. The newly described Damsel-in-Distress paradigm exposes a male mouse to a female mouse trapped in a chamber in the open center field of the arena. It provides an opportunity for the mouse to socially respond to the trapped female and exhibit prosocial behavior. The Damsel-in-Distress paradigm can also be used to examine mouse behavior in a novel arena and measure locomotor activity. Both the Barnes Maze and the Damsel-in-Distress protocols require minimal financial investment and most aspects of the tests can be constructed from common lab supplies. These flexible and accessible tools can also be used to detect behavioral changes over the course of development.

Inflammatory microglia are glycolytic and iron retentive and typify the microglia in APP/PS1 mice

Microglia, like macrophages, can adopt inflammatory and anti-inflammatory phenotypes depending on the stimulus. In macrophages, the evidence indicates that these phenotypes have different metabolic profiles with lipopolysaccharide (LPS)- or interferon-γ (IFNγ)-stimulated inflammatory cells switching to glycolysis as their main source of ATP and interleukin-4 (IL-4)-stimulated cells utilizing oxidative phosphorylation. There is a paucity of information regarding the metabolic signatures of inflammatory and anti-inflammatory microglia. Here, we polarized primary microglia with IFNγ and show that the characteristic increases in tumor necrosis factor-α (TNFα) and nitric oxide synthase 2 (NOS2) were accompanied by increased glycolysis and an increase in the expression of 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase (PFKFB)3, an enzyme that plays a significant role in driving glycolysis. These changes were associated with increased expression of ferritin and retention of iron in microglia. Significantly, retention of iron in microglia increased TNFα expression and also increased glycolysis suggesting that increased intracellular iron concentration may drive the metabolic and/or inflammatory changes. Analysis of microglia prepared from wildtype mice and from transgenic mice that overexpress amyloid precursor protein (APP) and presenilin 1 (PS1; APP/PS1) revealed genotype-related increases in glycolysis, accompanied by increased PFKFB3, and an increase in the expression of ferritin. The data indicate a distinct metabolic signature of inflammatory microglia from APP/PS1 mice that are also distinguishable by their iron handling profiles.

Maxillary expansion in an animal model with light, continuous force

OBJECTIVES

Maxillary constriction is routinely addressed with rapid maxillary expansion (RME). However, the heavy forces delivered by most RME appliances to expand the palate may lead to deleterious effects on the teeth and supporting tissues. The objective of this study was to explore a more physiologic maxillary expansion with light continuous force.

MATERIALS AND METHODS

Twenty 6-week-old Sprague-Dawley rats were equally divided into experimental (EXPT) and control (CTRL) groups. A custom-fabricated archwire expansion appliance made from 0.014-inch copper-nickel-titanium wire was activated 5 mm and bonded to the maxillary molar segments of animals in the EXPT group for 21 days. The force applied to each maxillary segment was 5 cN. Microfocus x-ray computed tomography and histological analyses were used to compare the tooth movement and bone morphology in the midpalatal suture and buccal aspect of the alveolar process between the EXPT and CTRL groups. Descriptive statistics (mean ± standard error of the mean) and nonparametric statistical tests were used to compare the outcomes across groups.

RESULTS

Compared to the CTRL group, there was a statistically significant increase in buccal tooth movement and expansion of the midpalatal suture in the EXPT group. There was no difference in the bone morphologic parameters between groups. The mineral apposition rate was increased on the buccal surface of the alveolar process in the EXPT group.

CONCLUSIONS

Application of light, continuous force resulted in maxillary osseous expansion due to bilateral sutural apposition and buccal drift of the alveolar processes. This animal experiment provides a more physiologic basis for maxillary expansion.

Study protocol for a randomised pragmatic trial comparing the clinical and cost effectiveness of lithium and quetiapine augmentation in treatment resistant depression (the LQD study)

BACKGROUND

Approximately 30-50% of patients with major depressive disorder can be classed as treatment resistant, widely defined as a failure to respond to two or more adequate trials of antidepressants in the current episode. Treatment resistant depression is associated with a poorer prognosis and higher mortality rates. One treatment option is to augment an existing antidepressant with a second agent. Lithium and the atypical antipsychotic quetiapine are two such add-on therapies and are currently recommended as first line options for treatment resistant depression. However, whilst neither treatment has been established as superior to the other in short-term studies, they have yet to be compared head-to-head in longer term studies, or with a superiority design in this patient group.

METHODS

The Lithium versus Quetiapine in Depression (LQD) study is a parallel group, multi-centre, pragmatic, open-label, patient randomised clinical trial designed to address this gap in knowledge. The study will compare the clinical and cost effectiveness of the decision to prescribe lithium or quetiapine add-on therapy to antidepressant medication for patients with treatment resistant depression. Patients will be randomised 1:1 and followed up over 12 months, with the hypothesis being that quetiapine will be superior to lithium. The primary outcomes will be: (1) time to all-cause treatment discontinuation over one year, and (2) self-rated depression symptoms rated weekly for one year via the Quick Inventory of Depressive Symptomatology. Other outcomes will include between group differences in response and remission rates, quality of life, social functioning, cost-effectiveness and the frequency of serious adverse events and side effects.

DISCUSSION

The trial aims to help shape the treatment pathway for patients with treatment resistant depression, by determining whether the decision to prescribe quetiapine is superior to lithium. Strengths of the study include its pragmatic superiority design, broad inclusion criteria (external validity) and longer follow up than previous studies.

Supervised pharmacy student-led medication review in primary care for patients with type 2 diabetes: a randomised controlled pilot study

OBJECTIVE

To pilot and feasibility-test supervised final year undergraduate pharmacy student-led medication reviews for patients with diabetes to enable definitive trial design.

METHOD

Third year pharmacy students were recruited from one UK School of Pharmacy and trained to review patient's medical records and provide face-to-face consultations under supervision while situated within the patient's medical practice. Patients with type 2 diabetes were recruited by postal invitation letter from their medical practice and randomised via automated system to intervention or usual care. Diabetes-related clinical data, quality of life, patient reported beliefs, adherence and satisfaction with medicines information were collected with validated tools at baseline and 6 months postintervention. The process for collecting resource utilisation data was tested. Stakeholder meetings were held before and after intervention to develop study design and learn from its implementation. Recruitment and attrition rates were determined plus the quality of the outcome data. Power calculations for a definitive trial were performed on the different outcome measures to identify the most appropriate primary outcome measure.

RESULTS

792 patients were identified as eligible from five medical practices. 133 (16.8%) were recruited and randomised to control (n=66) or usual care (n=67). 32 students provided the complete intervention to 58 patients. Initial data analysis showed potential for impact in the right direction for some outcomes measured including glycated haemoglobin, quality of life and patient satisfaction with information about medicines. The intervention was found to be feasible and acceptable to patients. The pilot and feasibility study enabled the design of a future full randomised controlled trial.

CONCLUSIONS

Student and patient recruitment are possible. The intervention was well received and demonstrated some potential benefits. While the intervention was relatively inexpensive and provided an experiential learning opportunity for pharmacy students, its cost-effectiveness remains to be determined.

A cohort study of influences, health outcomes and costs of patients' health-seeking behaviour for minor ailments from primary and emergency care settings

OBJECTIVES

To compare health-related and cost-related outcomes of consultations for symptoms suggestive of minor ailments in emergency departments (EDs), general practices and community pharmacies.

DESIGN

Observational study; prospective cohort design.

SETTING

EDs (n=2), general practices (n=6) and community pharmacies (n=10) in a mix of rural/urban and deprived/affluent areas across North East Scotland and East Anglia. Participants Adults (≥18 years) presenting between 09:00 and 18:00 (Monday-Friday) in general practices and 09:00-18:00 (Monday-Saturday) in pharmacies and EDs with ≥1 of the following: musculoskeletal pain; eye discomfort; gastrointestinal disturbance; or upper respiratory tract-related symptoms.

INTERVENTIONS

Participants completed three questionnaires: baseline (prior to index consultation); satisfaction with index consultation and follow-up (2 weeks after index consultation).

MAIN OUTCOME MEASURES

Symptom resolution, quality of life, costs, satisfaction and influences on care-seeking behaviour.

RESULTS

377 patients participated, recruited from EDs (81), general practices (162) and community pharmacies (134). The 2-week response rate was 70% (264/377). Symptom resolution was similar across all three settings: ED (37.3%), general practice (35.7%) and pharmacy (44.3%). Mean overall costs per consultation were significantly lower for pharmacy (£29.30 (95% CI £21.60 to £37.00)) compared with general practice (£82.34 (95% CI £63.10 to £101.58)) and ED (£147.09 (95% CI £125.32 to £168.85)). Satisfaction varied across settings and by measure used. Compared with pharmacy and general practice use, ED use was significantly (p<0.001) associated with first episode and short duration of symptom(s), as well as higher levels of perceived seriousness and urgency for seeking care. Convenience of location was the most common reason for choice of consultation setting.

CONCLUSIONS

These results suggest similar health-related outcomes and substantially lower costs with pharmacy consultations for minor ailments. Effective strategies are now needed to shift demand for minor ailment management away from EDs and general practices to the community pharmacy setting.

Does medical futility matter in 'do not attempt CPR' decision-making?

The current demographical trend towards an increasingly elderly population combined with advances in end of life care calls for a deeper understanding and common terminology about the concept of futility and additional influences on the resuscitation decision-making process. Such improved understanding of medical futility and other contributing factors when making DNACPR orders would help to ensure that clinicians make appropriate and thoughtful decisions on whether to recommend resuscitation in a patient. When estimating medical futility a physician should consider the chance of survival over different time periods and balance this against the chance of adverse outcomes. This information can then be offered to the patient (or the relatives) so that the patient's views about what is acceptable for the survival chance, length and type of survival can be factored into the eventual decision. Given the lack of evidence in this area and the poor level of patient knowledge and the emotive nature of the topic, it is not surprising that clinicians find such discussions hard.

Biomarkers: refining diagnosis and expediting drug development - reality, aspiration and the role of open innovation

In the last decade, there have been intensive efforts to invent, qualify and use novel biomarkers as a means to improve success rates in drug discovery and development. The biomarkers field is maturing and this article considers whether these research efforts have brought about the expected benefits. The characteristics of a clinically useful biomarker are described and the impact this area of research has had is evaluated by reviewing a few, key examples of emerging biomarkers. There is evidence that the impact has been genuine and is increasing in both the drug and the diagnostic discovery and development processes. Beneficial impact on patient health outcomes seems relatively limited thus far, with the greatest impact in oncology (again, both in terms of novel drugs and in terms of more refined diagnoses and therefore more individualized treatment). However, the momentum of research would indicate that patient benefits are likely to increase substantially and to broaden across multiple therapeutic areas. Even though this research was originally driven by a desire to improve the drug discovery and development process, and was therefore funded with this aim in mind, it seems likely that the largest impact may actually come from more refined diagnosis. Refined diagnosis will facilitate both better allocation of healthcare resources and the use of treatment regimens which are optimized for the individual patient. This article also briefly reviews emerging technological approaches and how they relate to the challenges inherent in biomarker discovery and validation, and discusses the role of public/private partnerships in innovative biomarker research.

Wrinkle reduction in post-menopausal women consuming a novel oral supplement: a double-blind placebo-controlled randomized study

Objective

The maintenance of youthful skin appearance is strongly desired by a large proportion of the world's population. The aim of the present study was therefore to evaluate the effect on skin wrinkling, of a combination of ingredients reported to influence key factors involved in skin ageing, namely inflammation, collagen synthesis and oxidative/UV stress. A supplemented drink was developed containing soy isoflavones, lycopene, vitamin C and vitamin E and given to post-menopausal women with a capsule containing fish oil.

Method

We have performed a double-blind randomized controlled human clinical study to assess whether this cocktail of dietary ingredients can significantly improve the appearance of facial wrinkles.

Results

We have shown that this unique combination of micronutrients can significantly reduce the depth of facial wrinkles and that this improvement is associated with increased deposition of new collagen fibres in the dermis.

Conclusion

This study demonstrates that consumption of a mixture of soy isoflavones, lycopene, vitamin C, vitamin E and fish oil is able to induce a clinically measureable improvement in the depth of facial wrinkles following long-term use. We have also shown, for the first time with an oral product, that the improvement is associated with increased deposition of new collagen fibres in the dermis.

Résumé

Determining in-patient diabetes treatment satisfaction in the UK--the DIPSat study

AIMS

To measure in-patient diabetes treatment satisfaction and its relationship to in-patient diabetes care.

METHODS

In a cross-sectional study, diabetes in-patient specialist nurses at 58 UK hospitals asked insulin-treated in-patients with diabetes to complete the recently updated Diabetes Treatment Satisfaction Questionnaire for In-patients and a general questionnaire; 1319 in-patients completed these questionnaires.

RESULTS

Satisfaction with the general diabetes treatment items in the Diabetes Treatment Satisfaction Questionnaire for In-patients was high, but there were high levels of extreme dissatisfaction with meal choices, meal quality and lack of similarity of hospital meals to normal domestic choices--23% would never or rarely have made similar meal choices at home. Hyperglycaemia or hypoglycaemia was reported for much of the in-patient stay (20% and 7%, respectively) and 26% reported at least one severe hypoglycaemic episode; these groups had lower satisfaction with the timing of medication in relation to meals (P < 0.003). More frequent in-patient hyperglycaemia or hypoglycaemia were associated with significantly poorer overall satisfaction scores and negative well-being scores (both P < 0.0001). Previous experience of a multiple daily insulin injection regimen was associated with more dissatisfaction than other regimens (P < 0.01). Multiple regression models explained 36% of variability in overall treatment satisfaction, with most (22.4%) accounted for by satisfaction with time spent with a diabetes in-patient specialist nurse (P < 0.0001). Self-administration of insulin was independently associated with higher treatment satisfaction (P < 0.006) in this model.

CONCLUSIONS

The DIPSat programme describes the complex relationships between diabetes in-patient treatment satisfaction and in-patient diabetes care.

A pragmatic randomised controlled trial of the effectiveness and cost-effectiveness of screening older women for the prevention of fractures: rationale, design and methods for the SCOOP study

SCOOP is a UK seven-centre, pragmatic, randomised controlled trial with 5-year follow-up, including 11,580 women aged 70 to 85 years, to assess the effectiveness and cost-effectiveness of a community-based screening programme to reduce fractures. It utilises the FRAX algorithm and DXA to assess the 10-year probability of fracture. Introduction Osteoporotic, or low-trauma, fractures present a considerable burden to the National Health Service and have major adverse effects on quality of life, disability and mortality for the individual. Methods Given the availability of efficacious treatments and a risk assessment tool based upon clinical risk factors and bone mineral density, a case exists to undertake a community-based controlled evaluation of screening for subjects at high risk of fracture, under the hypothesis that such a screening programme would reduce fractures in this population. Results This study is a UK seven-centre, unblinded, pragmatic, randomised controlled trial with a 5-year follow-up period. A total of 11,580 women, aged 70 to 85 years and not on prescribed bone protective therapy will be consented to the trial by post via primary care providing 90% power to detect an 18% decrease in fractures. Conclusions Participants will be randomised to either a screening arm or control. Those undergoing screening will have a 10-year fracture probability computed from baseline risk factors together with bone mineral density measured by DXA in selected subjects. Individuals above an age-dependent threshold of fracture probability will be recommended for treatment for the duration of the trial. Subjects in the control arm will receive 'usual care'. Participants will be followed up 6 months after randomisation and annually by postal questionnaires with independent checking of hospital and primary care records. The primary outcome will be the proportion of individuals sustaining fractures in each group. An economic analysis will be carried out to assess cost-effectiveness of screening. A qualitative evaluation will be conducted to examine the acceptability of the process to participants.

Republished original article: Resident-initiated interventions to improve inpatient heart-failure management

BACKGROUND

Third-year internal medicine residents participating in a quality improvement rotation identified gaps between the Joint Commission's ORYX quality guidelines and clinical practices for the inpatient management of heart failure (HF) at the William S. Middleton Memorial Veterans Hospital. Residents focused on the performance metrics associated with tobacco-cessation counselling documentation, ejection fraction assessment and angiotensin-converting enzyme inhibitor/angiotensin receptor blocker prescriptions.

METHODS

After analysing data collected by the External Peer Review Program, residents reviewed the institution's admissions and discharge processes with the aim of improving quality and compliance. In redesigning these processes, residents created an admissions template and a discharge face sheet, and compared specific ORYX measure compliance rates before and after institution-wide implementation.

RESULTS

Following implementation of the tobacco-cessation admissions template, 100% of HF patients who used tobacco received documented cessation counselling, compared with 59% prior to intervention (p<0.01, n=32). Following implementation of the mandatory discharge face sheet, 97% of HF patients (compared with 92% preintervention, p>0.05) received comprehensive discharge instruction; LV function assessment went from 98% to 100% (p>0.05); and angiotensin-converting enzyme inhibitor/angiotensin receptor blocker prescription for left ventricular systolic dysfunction at discharge (or documentation of a contra-indication) went from 82% to 100% (p<0.01, n=48).

DISCUSSION

By implementing a standardised admissions template and a mandatory discharge face sheet, the hospital improved its processes of documentation and increased adherence to quality-performance measures. By strengthening residents' learning and commitment to quality improvement, the hospital created a foundation for future changes in the systems that affect patient care.
