Industry Perceptions and Experiences with the Access Consortium New Active Substance Work-Sharing Initiative (NASWSI): Survey Results and Recommendations

The Access Consortium New Active Substance Work-Sharing Initiative, or "Access" for simplicity, allows regulatory authorities (RAs) of the Access Consortium countries to jointly review applications for the registration of new active substances or for new indications. Using a survey developed by the pharmaceutical industry trade associations of the five Access Consortium countries-Australia, Canada, Singapore, Switzerland, and the United Kingdom (UK)-this study gathered insights into the perceptions and experiences of the Access pathway held by affiliates of pharmaceutical companies. Understanding industry perceptions of Access is important for the success of the initiative, as participation is voluntary. Findings indicate that affiliates who participated in Access had mostly positive experiences with this pathway; most affiliates were satisfied with their interactions with the Access RAs and appeared willing to continue to participate in the initiative. Affiliates' reasons for not having yet participated in Access included a lack of opportunity to do so and perceived barriers, such as the Access pathway being too complicated to manage. Recommendations to improve Access cover six key areas: ensure predictability, increase guidance and transparency, streamline processes, maintain flexibility, increase harmonization, and advance RA-industry cooperation. This study should facilitate informed discussions among relevant stakeholders on how to improve Access to maximize efficiencies, accelerate approvals, and improve patient access to innovative medicines.

Assessing domain match and feasibility of candidate instruments matching with OMERACT endorsed domains to measure flare in knee and hip osteoarthritis

PURPOSE

To evaluate the domain match (truth) and feasibility of candidate instruments assessing flare in knee and hip osteoarthritis (OA) according to the identified domains.

MATERIAL AND METHODS

From a literature review (575 papers), instruments were selected and evaluated using the truth and feasibility elements of the OMERACT Filter 2.2. These were evaluated by 26 experts, including patients, in two Delphi survey rounds. The final selection was obtained by a vote.

RESULTS

44 instruments were identified. In Delphi Round 1, five instruments were selected. In Round 2, all instruments obtained at least 75 % in terms of content match with the endorsed domains and feasibility. In the final selection, the Flare-OA questionnaire obtained 100 % favorable votes.

CONCLUSION

Through consensus of the working group, the Flare-OA questionnaire was selected as the best candidate instrument to move into a full assessment of its measurement properties using the OMERACT Filter 2.2.

Absolute emission intensities of the gamma rays from the decay of 224Ra and 212Pb progenies and the half-life of the 212 Pb decay

Absolute gamma-ray emission intensities for 36 characteristic gamma rays from the decay of 224Ra, 212Pb, and their progeny were determined by measuring sources calibrated for activity by means of primary methods based on well-defined high-purity germanium (HPGe) detectors at both NIST and NPL. Results from the two laboratories agree with recent data evaluations, except for gamma rays with low emission intensities. The decay schemes have been re-balanced based on the new results. In addition, the half-life for 212Pb was measured using several HPGe detectors, ionization chambers, and a well-type NaI(Tl) detector.

Insights From a Community-Based Strategy to Assess Tobacco and Vape Shop Retailers' Implementation of Tobacco 21 Law in El Paso, Texas

In 2019, the United States Congress passed Tobacco 21 (T21) legislation that raised the minimum legal sales age for tobacco products from 18 to 21. However, although the federal legislation superseded weaker state laws that were already in place in some states, including Texas, local guidance for retailers was inconsistent. Given that retailers are ultimately responsible for policy implementation, the American Heart Association (AHA) initiated a process of assessing retailers knowledge and perceptions of the law through a survey targeting all tobacco retailers and accompanying ethnography of a subset of vape shops in El Paso, Texas. The process yielded lessons learned for assessment of community-based policy implementation including key considerations for personnel and process that are applicable to other community-based assessment processes. While AHA considered an in-person approach ideal, having an alternate online response option was necessary. In addition, a focused approach and in-depth understanding of the purpose was key to responsiveness of the retailers.

Systems-Level Evaluation of Safe Routes to School Policies in El Paso, Texas: A Modeling Study on Health and Economic Outcomes

Safe Routes to School (SRTS) policies are linked to physical health benefits for school-age children; however, few studies have assessed long-term impacts on cardiovascular disease (CVD). This study used systems science methods to predict long-term health and economic impact of SRTS among school-age children in El Paso County, Texas. We developed an agent-based model containing 2 modules: the pedestrian injury module and the CVD module. We simulated 10 000 school-age children under 2 scenarios-SRTS policies implemented and no SRTS policies implemented-and then calculated pedestrian injuries, pedestrian injury-related deaths, coronary heart disease (CHD) and stroke events, and health care costs. When SRTS policies were implemented, the model estimated 157 fewer CHD cases and 217 fewer stroke cases per 10 000 people and reduced CVD-related health care costs ($13 788 per person). The model also predicted 129 fewer pedestrian injuries and 1.3 injury-related deaths per 10 000 people and $2417 savings in injury-related health care costs. SRTS could save an estimated $16 205 per person in health care costs. This simulation shows SRTS in El Paso County could prevent pedestrian injuries among school-age children and protect cardiovascular health in the long term. Our findings provide evidence for practitioners and policy makers to advocate for SRTS policies at the local level.

Evaluating the prospective utility of pharmacogenetics reporting among Canadian Armed Forces personnel receiving pharmacotherapy: a preliminary assessment towards precision psychiatric care

Pharmacological interventions for treating posttraumatic stress disorder in Canadian Armed Forces (CAF) members and Veterans often achieve modest results. The field of pharmacogenetics, or the study of how genes influence an individual's response to different medications, offers insight into how prior knowledge of gene-drug interactions may potentially improve the trial-and-error process of drug selection in pharmacotherapy, thereby improving treatment effects and remission rates. Given the relative recency of pharmacogenetics testing and sparse research in military samples, we used pharmacogenetics testing in a small pilot group (n=23) of CAF members and Veterans who were already engaged in pharmacotherapy for a service-related mental health condition to better understand the associated opportunities and challenges of pharmacogenetics testing in this population. Our preliminary evaluation involved: (1) reporting the prevalence of pharmacogenetics testing 'bin' status according to participants' reports ('green', 'yellow' or 'red'; intending to signal 'go', 'caution' or 'stop', regarding the potential for gene-drug interactions); (2) calculating the percentage of currently prescribed psychotropic medications that were assessed and included in the reports; (3) evaluating whether prescribers used pharmacogenetics testing information according to clinical notes and (4) collecting informal feedback from participating psychiatrists. While pharmacogenetics testing appeared to provide valuable information for a number of clients, a major limitation was the number of commonly prescribed medications not included in the reports.

Librarian and Researcher Assessments of Search Result Relevance: How Well Do They Align?

Conducting comprehensive but efficient literature searches for complex evidence syntheses involves selecting databases that will retrieve the greatest number of relevant results on the question. Lack of a comprehensive single database on allied health educational topics challenges those seeking such literature. In this study, six participants contributed research questions on instructional methods and materials for allied health patients, caregivers, and future health professionals. Two health sciences librarians created search strategies for these questions and searched eleven databases. Both the librarians and the six participants evaluated the search results using a rubric based on PICO to assess extent of alignment between the librarians' and requestors' relevance judgments. Intervention, Outcome, and Assessment Method constituted the most frequent bases for assessments of relevance by both librarians and participants. The librarians were more restrictive in all of their assessments except in a preliminary search yielding twelve citations without abstracts. The study's results could be used to identify effective techniques for reference interviewing, selecting databases, and weeding search results.

Meaning in Life and Coping With Everyday Stressors

Meaning in life (MIL) has been proposed to improve coping and resilience. Yet MIL's association with coping has primarily been investigated in the context of extreme stressors and trauma, often using varied measures of MIL. Is MIL associated with varied coping strategies, coping self-efficacy, and distress in relation to commonly experienced, everyday challenges? Using diverse methodological designs, five studies (total N = 1,646) investigated the association between MIL and coping strategies/appraisals pertaining to varied challenging, stressful events. Across recalled (Studies 1 and 2), anticipated (Study 3), and experienced stressors (Studies 3-5), MIL was consistently associated with positive reinterpretation, proactive planning, coping self-efficacy, and stress. MIL was inconsistently related to threat/emotion-coping.

Regional Variation in Outpatient Antibiotic Prescribing for Acute Respiratory Tract Infections in a Commercially Insured Population, United States, 2017

Background

Studies have shown that the Southern United States has higher rates of outpatient antibiotic prescribing rates compared with other regions in the country, but the reasons for this variation are unclear. We aimed to determine whether the regional variability in outpatient antibiotic prescribing for respiratory diagnoses can be explained by differences in prescriber clinical factors found in a commercially insured population.

Methods

We analyzed the 2017 IBM MarketScan Commercial Database of commercially insured individuals aged <65 years. We included visits with acute respiratory tract infection (ARTI) diagnoses from retail clinics, urgent care centers, emergency departments, and physician offices. ARTI diagnoses were categorized based on antibiotic indication. We calculated risk ratios and 95% CIs stratified by ARTI tier and region using log-binomial models controlling for patient age, comorbidities, care setting, prescriber type, and diagnosis.

Results

Of the 14.9 million ARTI visits, 40% received an antibiotic. The South had the highest proportion of visits with an antibiotic prescription (43%), and the West the lowest (34%). ARTI visits in the South are 34% more likely receive an antibiotic for rarely antibiotic-appropriate ARTI visits when compared with the West in multivariable modeling (relative risk, 1.34; 95% CI, 1.33-1.34).

Conclusions

It is likely that higher antibiotic prescribing in the South is in part due to nonclinical factors such as regional differences in clinicians' prescribing habits and patient expectations. There is a need for future studies to define and characterize these factors to better inform regional and local stewardship interventions and achieve greater health equity in antibiotic prescribing.

Prevalence and correlates of stocking up on drugs during the COVID-19 pandemic: Data from the C3PNO Consortium

BACKGROUND

Data from the COVID-19 pandemic describes increases in drug use and related harms, especially fatal overdose. However, evidence is needed to better understand the pathways from pandemic-related factors to substance use behaviours. Thus, we investigated stockpiling drugs among people who use drugs (PWUD) in five cities in the United States and Canada.

METHODS

We used data from two waves of interviews among participants in nine prospective cohorts to estimate the prevalence and correlates of stockpiling drugs in the previous month. Longitudinal correlates were identified using bivariate and multivariate generalized linear mixed-effects modeling analyses.

RESULTS

From May 2020 to February 2021, we recruited 1873 individuals who completed 2242 interviews, of whom 217 (11.6%) reported stockpiling drugs in the last month at baseline. In the multivariate model, stockpiling drugs was significantly and positively associated with reporting being greatly impacted by COVID-19 (Adjusted Odds Ratio [AOR]= 1.21, 95% CI: 1.09-1.45), and at least daily use of methamphetamine (AOR = 4.67, 95% CI: 2.75-7.94) in the past month.

CONCLUSIONS

We observed that approximately one-in-ten participants reported stocking up on drugs during the COVID-19 pandemic. This behaviour was associated with important drug-related risk factors including high-intensity methamphetamine use. While these correlations need further inquiry, it is possible that addressing the impact of COVID-19 on vulnerable PWUD could help limit drug stockpiling, which may lower rates of high-intensity stimulant use.

153 AN EVALUATION OF OLDER PERSONS WITH VESTIBULAR DYSFUNCTION AS IDENTIFIED DURING COMPREHENSIVE GERIATRIC ASSESSMENT

Background

Vestibular dysfunction accounts for 25% of dizziness complaints. In 30-50% of these cases, dizziness is attributed to Benign Paroxysmal Positional Vertigo (BPPV). Thirty percent of people will experience vestibular dysfunction in their lifetime, with likelihood increasing with age. Individuals with vestibular dysfunction are eight times more likely to experience a fall. Vestibular assessment and rehabilitation services can be difficult to access.

Methods

A Plan, Do, Study, Act (PDSA) cycle was undertaken. All referrals to the Older Persons’ Services Clinics from November 2021 to May 2022 were triaged by an Integrated Care Team for the Older Person and scheduled for Comprehensive Geriatric Assessment (CGA). In the course of CGA, patients who reported symptoms suggestive of vestibular dysfunction received assessment by a Physiotherapist with vestibular expertise. Results were entered on an Excel spreadsheet and analysed using descriptive statistics.

Results

Six patients (4 female, 2 male) received vestibular assessment and treatment. Mean age was 75 years (SD: 11) with median Clinical Frailty Score of 4 (vulnerable). Reported symptoms were dizziness (n=3) and spinning (n=3). Sixteen percent (n=1) reported a fall and 66% (n=4) reported fear of falling. All patients had symptom duration of &gt;2 years. Following vestibular assessment, the following diagnoses were made; right posterior canal BPPV, (n=2), vestibular migraine (n=2), right horizontal canal canalithiasis BPPV, with secondary diagnosis of persistent postural-perceptual dizziness (n=1) and left peripheral vestibular hypofunction due to vestibular neuronitis (n=1). The mean number of Physiotherapy visits per person was 4. Three patients reported full resolution of symptoms. The remaining 3 reported an improvement in symptoms and confidence to self-manage.

Conclusion

This small cohort of older persons with chronic vestibular dysfunction benefited from vestibular diagnosis and intervention. The next step of the process is to include specific vestibular screening questions into CGA. This will enable Integrated Care Team members to screen more specifically for vestibular dysfunction.

233 COGNITIVE OUTCOMES AFTER A FIRST EPISODE OF DELIRIUM IN HOSPITAL – RESULTS FROM AN ADVANCED NURSE PRACTITIONER DELIRIUM CLINIC

Background

Cognitive outcomes for frail older adult inpatients with a first episode of Delirium are unknown. Aim: To determine cognitive outcomes of frail older inpatients after a first episode of Delirium.

Methods

Consecutive frail older inpatients with a 4AT score &gt;/= 4, without a previous history of cognitive impairment, over a 12-month period (January to December 2021) were invited for formal cognitive assessment 8-12 weeks after their delirium occurred. Collateral history, medication review, Addenbrookes (ACE III), bloods and CT brain were undertaken. Data was prospectively entered onto Excel and analysed using descriptive statistics.

Results

Fifty-one patients with a mean age of 82 years (SD=6) were referred to the Advanced Nurse Practitioner (ANP) Delirium Clinic. Median Clinical Frailty Score (CFS) was 6 with a male: female ratio of 1:2. Forty- seven percent (n=24) attended; 35 % (n-18) did not attend; 18 % (n=9) died prior to assessment. The ratio of male to female attendees was 1: 2.4. There was no difference in CFS or age between attenders and non-attenders. Thirty-three percent (n=8) of patients who attended had potentially reversible causes (high anti-cholinergic burden, folate deficiency, sleep disorder) of cognitive impairment requiring intervention. Sixty-seven percent (n=16) were diagnosed with dementia at the Delirium Clinic; 16.6% (n=4) were diagnosed with Mild Cognitive Impairment; 4% (n=1) had a resolved delirium; 8% (n=2) were referred to consultant Memory Clinic and one patient remained too unwell to assess. The median ACE III score of patients diagnosed with dementia was 54/100 (SD = 18).

Conclusion

Pro-active follow up of patients with a first episode of Delirium led to early diagnosis of dementia and mild cognitive impairment with supportive interventions. Earlier ANP intervention, during the acute phase of delirium, has been introduced in order to improve clinic attendance.

330 RISK OF MALNUTRITION AND ITS ASSOCIATION WITH FRAILTY-ASSOCIATED FACTORS IN THE OLDER PERSON

Background

The aetiology of malnutrition is multifactorial, with age a facilitating factor. It is associated with poorer physical and mental health and functional ability in frail older persons. Nutritional screening is a key domain in Comprehensive Geriatric Assessment (CGA). This study assessed the relationship between malnutrition risk and other drivers of frailty in the older person by CGA.

Methods

All patients who had a CGA completed by an Integrated Care Team for Older Persons from March 2020 to July 2021 inclusive were studied. Data was entered onto an Excel database by a trained administrator. The variables included were: age, gender, swallow screen, living alone, cognition, loneliness, Clinical Frailty Scale (CFS) score, falls history and risk of malnutrition using the Malnutrition-Screening Tool (MST). Odds ratio (OR), 95% Confidence Intervals (CI) was used to determine if there was an association between malnutrition risk and each variable in the total group.

Results

In total, 567 patients (325 female, 242 male), mean age 82yrs (SD =19), with median CFS of 6 were studied. Sixty-eight percent (n=384) reported a fall, 37.2% (n=211) had a positive swallow screen, 44% (n=251) lived alone, 35% (n=198) had positive cognitive screening, 14% (n=80) reported loneliness and 31.6% (n=179) were identified as at risk of malnutrition. A positive association was identified between risk of malnutrition and cognitive impairment (OR 1.9, 95%CI 1.2-3.1) and a reported fall (OR 2.2, 95%CI 1.4-3.5). In the population who had a fall and risk of malnutrition, the association remained in those aged ≥80yrs (OR 2.6, 95% CI 1.46 – 4.5) and female (OR 3.6, 95%CI 1.7 – 7.4).

Conclusion

The risk of malnutrition is associated with falls risk and cognitive impairment in frail older persons. Frail older persons identified by integrated care team for older persons with falls risk & cognitive impairment will be targeted for specialist dietetic intervention.

Serum concentration trends and apparent half-lives of per- and polyfluoroalkyl substances (PFAS) in Australian firefighters

BACKGROUND

Per- and polyfluoroalkyl substances (PFASs) are persistent manmade compounds used in aqueous film forming foam (AFFF). The extensive use of AFFF has led to widespread environmental PFAS contamination and exposures of firefighters.

OBJECTIVES

To determine PFAS blood serum concentration trends and apparent serum half-lives in firefighters after the replacement of AFFF.

METHODS

Current and former employees of an Australian corporation providing firefighting services, where AFFF formulations had been used since the 1980s up until 2010, were recruited in 2018-2019 to participate in this study. Special focus was put on re-recruiting participants who had provided blood samples five years prior (2013-2014). Participants were asked to provide a blood sample and fill in a questionnaire. Serum samples were analysed for 40 different PFASs using HP LC-MS/MS.

RESULTS

A total of 799 participants provided blood samples in 2018-2019. Of these, 130 previously provided blood serum in 2013-2014. In 2018-2019, mean (arithmetic) serum concentrations of perfluorooctane sulfonate (PFOS, 27 ng/mL), perfluoroheptane sulfonate (PFHpS, 1.7 ng/mL) and perfluorohexane sulfonate (PFHxS, 14 ng/mL) were higher than the levels in the general Australian population. Serum concentrations were associated with the use of PFOS/PFHxS based AFFF. Participants who commenced service after the replacement of this foam had serum concentrations similar to those in the general population. Mean (arithmetic) individual apparent half-lives were estimated to be 5.0 years (perfluorooctanoic acid (PFOA)), 7.8 years (PFHxS), 7.4 years (PFHpS) and 6.5 years (PFOS).

CONCLUSION

This study shows how workplace interventions such as replacement of AFFF can benefit employees at risk of occupational exposure.

The health and economic impact of the Tobacco 21 Law in El Paso County, Texas: A modeling study

In December 2019, the US federal Tobacco 21 (T21) law passed to raise the minimum legal purchase age for tobacco products from 18 to 21 years. Preliminary evidence suggests that the T21 law will restrict youth access to tobacco products, leading to decreases in tobacco use over their lifetime. This study expands the science through the use of systems modeling by linking decreases in youth tobacco use in El Paso County, Texas, due to the T21 law implementation, to potential cardiovascular health (CVH) benefits and health care cost reductions. Using a smoking behavior and cardiovascular disease agent-based model, we projected the T21 law's long-term effects on smoking prevalence and CVH outcomes in El Paso County, Texas. The estimated smoking prevalence in El Paso County, Texas, decreased by 2.7% among 18-24 year olds and by 5.2% among 25-44 year olds in 20 years with T21 law implementation (p < 0.01 for both population groups). By reducing tobacco use, the T21 law could prevent 5.4 coronary heart disease events per 1,000 adults and 6.1 S events per 1,000 adults over a lifetime. The model estimated a reduction in lifetime health care costs from $42,929 per person without T21 law to $41,985 per person with the policy. This study provides further evidence for policymakers and communities to understand the potential health and economic impacts of the federal T21 law at the local level. Results emphasize the need for comprehensive policy implementation and enforcement to produce its intended impact on health outcomes.

Concussion Management Guidelines Neglect Auditory Symptoms

Tinnitus, noise sensitivity, and hearing difficulties are commonly reported secondary to head injury. These auditory deficits have been shown to negatively impact daily functioning, and yet, often go unnoticed by health care professionals. The purpose of this editorial is to explain why it is essential for clinical practice guidelines that address the management of patients who have experienced a head injury to incorporate assessment and rehabilitation of auditory symptoms.

Quantifying evidence toward pathogenicity for rare phenotypes: The case of succinate dehydrogenase genes, SDHB and SDHD

PURPOSE

The weight of the evidence to attach to observation of a novel rare missense variant in SDHB or SDHD in individuals with the rare neuroendocrine tumors, pheochromocytomas and paragangliomas (PCC/PGL), is uncertain.

METHODS

We compared the frequency of SDHB and SDHD very rare missense variants (VRMVs) in 6328 and 5847 cases of PCC/PGL, respectively, with that of population controls to generate a pan-gene VRMV likelihood ratio (LR). Via windowing analysis, we measured regional enrichments of VRMVs to calculate the domain-specific VRMV-LR (DS-VRMV-LR). We also calculated subphenotypic LRs for variant pathogenicity for various clinical, histologic, and molecular features.

RESULTS

We estimated the pan-gene VRMV-LR to be 76.2 (54.8-105.9) for SDHB and 14.8 (8.7-25.0) for SDHD. Clustering analysis revealed an SDHB enriched region (ɑɑ 177-260, P = .001) for which the DS-VRMV-LR was 127.2 (64.9-249.4) and an SDHD enriched region (ɑɑ 70-114, P = .000003) for which the DS-VRMV-LR was 33.9 (14.8-77.8). Subphenotypic LRs exceeded 6 for invasive disease (SDHB), head-and-neck disease (SDHD), multiple tumors (SDHD), family history of PCC/PGL, loss of SDHB staining on immunohistochemistry, and succinate-to-fumarate ratio >97 (SDHB, SDHD).

CONCLUSION

Using methodology generalizable to other gene-phenotype dyads, the LRs relating to rarity and phenotypic specificity for a single observation in PCC/PGL of a SDHB/SDHD VRMV can afford substantial evidence toward pathogenicity.

124 OUTCOME OF SPEECH AND LANGUAGE THERAPY CLINICAL DYSPHAGIA ASSESSMENT FOLLOWING AN INTERDISCIPLINARY SWALLOW SCREEN

Background

A 7 question non-validated swallow screen (Any reported swallowing difficulties? Any coughing with food or fluids? Any choking? Does food get stuck when eating? Any recurrent chest infections? Any pain when swallowing? Any difficulty swallowing tablets?) is used by an integrated care team for older persons to prioritise referrals to the Speech and Language Therapy (SLT) service.

This study identified the proportion of patients screened who appropriately required a clinical dysphagia assessment and intervention.

Methods

This was a retrospective study from September 2020 to June 2021. Patients were assessed by the Clinical Specialist SLT who determined if swallow impairment was present and whether intervention was required. Age, gender and clinical frailty score were documented. Patients who resided out of the catchment area or who had already received an SLT service were excluded.

Results

The average age was 80 years, range 67–103. The male to female ratio was 2:1 and the average clinical frailty score (CFS) was 5. N = 42(32%) screened positive. N = 29(69%) attended for SLT assessment. N = 27(93.1%) had a swallow impairment identified. N = 20 were discharged following a single intervention and 9 required further SLT intervention.

Conclusion

Presbyphagia is generally asymptomatic and results from age related anatomical and physiological changes, reduced functional reserve and sarcopenia. Older adults compensate for these difficulties and do not seek assistance. Presbyphagia may progress to dysphagia, resulting in adverse outcomes. The high rate of SLT confirmed swallow impairment and need for SLT intervention highlights a need to prospectively refine and validate this 7 question swallow screen.

44 BONE HEALTH AND FRACTURE RISK: KNOWLEDGE, OPINION AND PRACTICE OF PHYSIOTHERAPISTS

Background

Osteoporotic-related fractures are responsible for excess mortality, morbidity, chronic pain, reduction in quality of life, admission to long-term care and health and social care costs (Papaioannou et al, 2010).

Evidence for using Fracture Risk Assessment Tool (FRAX®) based community-screening in older people is increasing (Kanis et al, 2020). There is no published evidence on the use of FRAX® by Physiotherapists.

Methods

A questionnaire was sent to South Eastern Branch members of the Irish Society of Chartered Physiotherapists (ISCP).

Survey themes were: participant characteristics, knowledge and opinion in the areas of Bone Health and Fracture Risk. Responses were downloaded from Survey Monkey and analysed using descriptive statistics.

Results

The response rate was 27% (n = 56). 72% (n = 40) of those surveyed had at least 10 years clinical experience. For 65% (n = 37) of participants, older people made up more than half of their clinical caseload. 96% (n = 54) of participants treated people with frailty and other bone health risk factors; falls (93%), osteoporosis (89%), fracture or reduced mobility (87%).

On a scale of 1–10 (1 = least confident, 10 = most confident) 49% of respondents rated confidence in prescribing Bone Health Physiotherapy interventions at ≤5.

When interpreting results of a DEXA scan; 80% reported confidence to be ≤5.

Half (49%) of participants had never heard of FRAX®.

95% of respondents felt fracture risk was under addressed in clinical practice. All felt it was within their professional responsibility to discuss fracture risk with patients.

Conclusion

This is the first evaluation of bone health and fracture risk knowledge, opinion and practice of physiotherapists. The need for more knowledge of DEXA, FRAX® and bone health was highlighted. The use of FRAX® may improve fracture risk assessment in patients attending Physiotherapy. Based on these results, FRAX® has been introduced into a Rehabilitation Unit by Physiotherapists as part of Quality Improvement Project.

126 A QUALITY INITIATIVE TO IMPROVE THE ASSESSMENT AND RECOMMENDATION FOR TOTAL CALCIUM INTAKE

Background

This study assessed factors affecting adherence to calcium supplementation, estimated total calcium intake and potential to increase dietary calcium in the frail older adult.

Methods

Frail Older Adults who completed a comprehensive geriatric assessment (CGA) between January—June 2021 were included. Those taking calcium supplements were telephoned by a Dietitian. Nursing home residents, hospital inpatients and those unable to complete a telephone questionnaire were excluded. A modified version of the Short Calcium Intake List (SCAIL) was used and potential to improve dietary calcium was assessed (1). Data was analysed using descriptive statistics.

Results

N = 50 patients were taking a calcium supplement. N = 15 were excluded. 26 women and 9 men, aged 70 -96 yrs were included. Dietary intake ranged from 250– 1904 mg. 17% (N = 6) achieved &gt;1,000 mg/day dietary calcium requirements from diet. 66% (N = 23) had potential to increase their dietary calcium. 97% (N = 34) were prescribed a Calcium supplement, ranging from 500– 2000 mg/day. Total Calcium Intake including supplementation ranged from 850 mg—2,737 mg. 82% (N = 29) exceeded their daily requirements.40% (N = 14) reported reduced compliance due to swallowing difficulties; 25%(N = 9) gastrointestinal upset; 11% (N = 4,) taste/consistency and 8% forgetting (N = 3).Dietitian recommendations included 31% (N = 11) to stop supplementation, 34% (N = 12) to reduce, 11% (N = 4) advice on managing concerns relating to supplement and 22% (N = 8) dietary education.

Conclusion

Most older adults did not meet their nutritional requirements for dietary calcium. Over two thirds could reduce or stop supplementation following dietary calcium assessment and advice. A dietary calcium estimator for the older adult, with education can be used to correct calcium intake. This modified SCAIL will be integrated into the CGA as part of a quality improvement initiative for the frail older adult.

POS0270-HPR FLARE-OA QUESTIONNAIRE TO MEASURE FLARES IN OSTEOARTHRITIS OF THE KNEE AND HIP: ASSESSMENT OF ITS PSYCHOMETRIC PROPERTIES

Background:

Hip and knee OA is characterised by disease flares – understanding the determinants and consequences of OA flares has been hampered by lack of a standardized flare measure beyond the pain aspect. The patients point of view on the different aspect of their flares is essential.

Objectives:

The objective was to assess the psychometric properties of a new questionnaire for measuring the multidimensional aspect of flares in OA.

Methods:

Using a bilingual version of the questionnaire (33 items, response on a numeric scale, from 0 to 10), a multicentre survey (Australia, France and United States) was conducted on line with patients diagnosed with OA of the hip and/or the knee. Based on an international OMERACT/OARSI endorsed definition of the five core domains (pain, swelling, stiffness, consequences of symptoms and psychological aspects) composing a flare in OA [1], a confirmatory factorial analysis linked to the content analysis has been used to reduce the number of items and to determine the validity of the structure. The Flare-OA questionnaire (score from 0 to 100) has been tested in French and English for its internal consistency, its convergent validity with HOOS/KOOS and Mini-OAKHQOL questionnaires, and its discriminant validity.

Results:

Out of 398 patients (mean age 64 years old) who completed the questionnaire, 70.4% were female and 86.7% had knee OA. The confirmatory factorial analysis retained a model with 19 items (RMSEA =0.06; SRMR =0.04; CFI =0.96 and TLI = 0.94). The Cronbach Alpha was > 0.9 for the 5 domains and for the whole questionnaire. The correlations between the Flare-OA and the other instruments were in line with that hypothesis flare is related but different from other concepts usually measured. The discriminant validity was evidenced by a significant score difference (31.8; p<0,0001) between patients with and without flare, i.e. over twice the standard measurement error.

Conclusion:

The optimized Flare-OA questionnaire (19 items) is a reliable and valid instrument freely available from the authors for measuring the frequency and severity of flare in knee and hip OA in clinical research.

Common mental disorders among Irish jockeys: prevalence and risk factors

OBJECTIVE

Jockeys compete in a sport, horseracing, renowned for its physical and psychological demands. Previous research has identified that common mental disorders (CMDs) may be prevalent among this unique population of athletes. The aim of the present study was to further explore the prevalence of CMDs among jockeys and to test for associations with potential risk factors.

METHODS

An anonymous survey was distributed to professional jockey online. Self-report screening tools for four CMDs (psychological distress, depression, generalized anxiety, and adverse alcohol use) were included alongside predictor variables from questionnaires assessing for burnout, career satisfaction, social support, and the contemplation of retirement. Binary logistic regression was used to explore associations between CMDs (present versus not present) and risk factors. Eighty-four professional jockeys completed the questionnaire (response rate = 52%).

RESULTS

In total, 79% of jockeys met the threshold for at least one CMD. Prevalence (%) of CMD varied as follows: adverse alcohol (61%), depression (35%), generalized anxiety (27%), and psychological distress (19%). Burnout, career (dis)satisfaction, lower levels of social support, and the contemplation of retirement increased the odds of meeting the criteria for CMDs.

CONCLUSION

The findings indicate that jockeys report CMD symptoms at comparable rates to athletes in other sports. The study was the first to highlight potential risk factors as predictors of CMDs among jockeys, including burnout, career satisfaction, and the current contemplation of retirement. Screening tools for the risk factors demonstrated may, therefore, provide useful in the early identification of CMDs among jockeys. The development of jockey-specific assessment tools, education programmes, and interventions may help better understand and support the mental health of jockeys.

142 Improving Functional Outcomes During Covid-19 for Both COVID-19 and Non COVID-19 Positive Older Adults Through the Introduction

Purpose

To improve the functional outcomes of older adults presenting to the Health and Ageing wards during the COVID-19 pandemic through a focussed rehabilitation list. The intended benefits to the older adult and service were for: 1. Daily rehabilitation input for older adults. 2. Older adults to spend less time immobile. 3. Ongoing rehabilitation intervention while awaiting medical clearance for discharge. 4. Increased staff satisfaction 5. Better outcomes on discharge. 6. Rehabilitation ethos on the Health and Ageing wards.

Methods

The quality improvement project was carried out using the Plan, Do, Study, Act (PDSA) cycle. Three iterative PDSA cycles were carried out over the course of the project to deliver proactive interventions as a result of analysis of baseline data and stakeholder involvement. These interventions were aimed at developing communication around the rehabilitation list within the team and sustainability of this list.

Results

The project resulted in better functional outcomes for older adults and increased staff morale. Between May 2020–June 2020, a total of 56 patients were seen on the rehabilitation list, with 84% of these patients seeing improvements in their Elderly Mobility Scores (EMS). 27% of patients on the rehabilitation list saw a change to their initial discharge plan, either needing reduced packages of care or reduced need for ongoing rehabilitation in an external setting.

Conclusions

The quality improvement project found that with focussed rehabilitation older adult inpatients with or without COVID-19 can make significant functional gains. These gains have wider effects on their outcomes on discharge and also for the service through increased morale and job satisfaction. Due to demand and capacity issues in the acute setting, older adults who would often benefit from ongoing input are not always reviewed regularly. This project demonstrates that with focussed rehabilitation older adults can improve and achieve better functional outcomes.

Determination of the half-life and the absolute photon emission intensities for the main gamma-ray energies of 124I

The National Institute of Standards and Technology (NIST) performed new standardization measurements for ¹²⁴I. As part of this work the absolute photon emission intensity for the main gamma-rays of ¹²⁴I were determined using several high-purity germanium (HPGe) detectors. In addition, the half-life for ¹²⁴I was also determined using an HPGe detector. Ionization chamber measurements were performed for additional sources, but it was not possible to obtain a precise half-life value.

Healthy choices in New South Wales health facilities for staff and visitors: a policy evaluation

Issue

Obesity and its determinants are risk factors for most leading causes of chronic diseases. In New South Wales (NSW), Australia, 1 in 2 adults and more than 1 in 5 children are above a healthy weight. As a key symbolic part of a suite of health eating policies, the NSW Ministry of Health implemented a Healthy Food and Drink in NSW Health facilities for Staff and Visitors Framework (Framework) across 18 Local Health Districts (LHDs). Many countries are grappling to understand the effectiveness of obesity prevention policies. Description 2: This policy evaluation synthesised evaluation study findings and internal records to assess the effectiveness of the Framework in achieving implementation targets: a) the removal of sugar-sweetened drinks (SSDs) from sale (Dec 2017), b) implementation of 12 food-based practices (Dec 2018).

Results

The overall implementation package was appropriate for the large, geographically dispersed, decentralised health system (160 health facilities; 927 food outlets;76 retailers) and variable retail arrangements. The Ministry provided LHDs with overall direction, phasing, and monitoring; the LHDs had local leadership, governance, cross-functional support and autonomy to implement in a way to suit them. Accountability and pace of implementation was driven most notably by monitoring and reporting using an electronic tool (PHIMS-N), and a 'network of practice' that was pivotal to problem solving. SSDs were removed from 96% (n = 606) of applicable food outlets; overall average achievement of all practices was high at 82% (22.4 SD). Nine in 10 (92%) consumers support the Framework, and retailers are accepting of its targets. Lessons: This was the right policy at the right time, with well-orchestrated implementation. Annual monitoring and reporting enabled by PHIMS-N is unique in this type of policy implementation and essential for tracking progress, informing decision making, and ensuring accountability.

Key messages

Implementation of the Framework has resulted in the removal of SSDs from sale, increased availability of healthier foods and decreased unhealthy foods as measured by 12 food-based practices. The Framework is feasible and effective in influencing retail practices in health facilities, has high consumer support for its goals, and overall acceptability and adoption amongst retailers.

New MPH curriculum in the United States: Report on successes and challenges

Background

In October 2016, the Council on Education for Public Health, the US accreditation agency for Master of Public Health (MPH) programs, revised its criteria. The new curricular model transitions a nearly 100-year-old knowledge-based curriculum to a competency-based curriculum tailored to today's public health needs in a global society. This presentation will highlight the new content and format of MPH curricula, including programs outside the US that have participated in US accreditation.

Objectives

CEPH has tracked implementation of the new curriculum as well as overall redesign of MPH programs. The presentation will describe strengths and challenges faced by programs implementing new curricula and will describe innovative curricular models.

Results

Data show that MPH programs are strong in epidemiological methods (99%), interpreting data (99%), and designing population-based policies or programs (93%). Programs have struggled to incorporate interprofessional practice (57%), systems thinking tools (55%), and negotiation skills (59%). Data indicate that 13% retained coursework in the traditional five core disciplines; 69% added to or adjusted the core; and 18% created a new or integrated core. Examples of each structure will be provided.

Conclusions

MPH programs in the US are experiencing a major change focused on development of competencies and skills for practice. While methodological skills remain strong, “soft” skills that are important for global public health practice are more of a challenge for faculty to integrate into the current training structure. Successful programs are incorporating innovative and cross-cutting curricula to meet these new requirements.

Key messages

MPH curricular requirements in the US have changed to focus on competencies and skills for public health practice. Critical public health leadership skills such as negotiation and interprofessional communication are lagging behind in integration into the new curriculum.

Engaging ignored stakeholders of higher education accessibility practice: analysing the experiences of an international network of practitioners and researchers

Purpose

The purpose of this paper is to examine and critique current approaches of higher education (HE) community concerning stakeholder engagement in the development of information and communications technology (ICT) related accessibility practice.

Design/methodology/approach

The approach taken to this examination is to draw on presentations, panel discussions and World Café reflections from an international symposium held in Montreal where researchers and practitioners debated two key questions as follows: have all the relevant stakeholders really been identified? Are there some stakeholders that the HE community has ignored? And what factors influence successfully distributed ownership of the accessibility mission within HE institutions?

Findings

A number of “new” internal and external stakeholders are identified and it is argued that if they are to be successfully engaged, effort needs to be invested in addressing power imbalances and developing opportunities for successful strategic silo-crossing.

Originality/value

The value of this paper is in critiquing the argument that all stakeholders in the development of accessible ICT in HE need to be involved, identifying a gap in the argument with respect to whether all relevant stakeholders have actually been engaged and offering insights into this omission might be rectified.

Quantifying Soft Tissue Artefacts and Imaging Variability in Motion Capture of the Fingers

This study assessed the accuracy of marker-based kinematic analysis of the fingers, considering soft tissue artefacts (STA) and marker imaging uncertainty. We collected CT images of the hand from healthy volunteers with fingers in full extension, mid- and full-flexion, including motion capture markers. Bones and markers were segmented and meshed. The bone meshes for each volunteer's scans were aligned using the proximal phalanx to study the proximal interphalangeal joint (PIP), and using the middle phalanx to study the distal interphalangeal joint (DIP). The angle changes between positions were extracted. The HAWK protocol was used to calculate PIP and DIP joint flexion angles in each position based on the marker centroids. Finally the marker locations were 'corrected' relative to the underlying bones, and the flexion angles recalculated. Static and dynamic marker imaging uncertainty was evaluated using a wand. A strong positive correlation was observed between marker- and CT-based joint angle changes with 0.980 and 0.892 regression slopes for PIP and DIP, respectively, and Root Mean Squared Errors below 4°. Notably for the PIP joint, correlation was worsened by STA correction. The 95% imaging uncertainty interval was < ± 1° for joints, and < ± 0.25 mm for segment lengths. In summary, the HAWK marker set's accuracy was characterised for finger joint flexion angle changes in a small group of healthy individuals and static poses, and was found to benefit from skin movements during flexion.

The effect of copper-oxide-treated soft and hard surfaces on the incidence of healthcare-associated infections: a two-phase study

BACKGROUND

Copper-oxide-impregnated linens and hard surfaces within the hospital environment have emerged as a novel technology to reduce environmental contamination and thereby potentially reduce the risk of healthcare-associated infections (HCAIs).

METHODS

This was a two-phase study. Phase 1 was a prospective, cluster-randomized, cross-over clinical trial in which one pod (eight beds) of our general ICU (GICU) utilized copper-oxide-impregnated linens whereas the other pod (eight beds) used standard hospital linens. Phase 2 was a two-year before-after study, following the relocation of three ICUs into a new ICU tower in which all the hard surfaces were treated with copper oxide (in addition to copper-impregnated linens). HCAIs were recorded using the National Healthcare Safety Network definitions.

FINDINGS

A total of 1282 patients were enrolled in phase 1. There was no difference in the rate of HCAI between the patients who received standard compared with copper oxide linen. In phase 2 there was a significant reduction in the number of infections due to Clostridioides difficile (2.4 per 1000 vs 0.7 per 1000 patient-days; incidence rate ratio: 3.3; 95% confidence interval: 1.4-8.7; P = 0.002) but no difference in the rate of central-line-associated bloodstream infections nor of catheter-associated urinary tract infections.

CONCLUSION

Copper-oxide-impregnated linens alone had no effect on the rate of HCAI. Our data suggest that copper-oxide-treated hard surfaces reduced the rate of infections due to C. difficile; however, important confounders cannot be excluded.

Determination of the internal pair production branching ratio of 90Y

The National Institute of Standards and Technology (NIST) measured the internal pair production branching ratio of ⁹⁰Y using two sources and four high purity germanium (HPGe) detectors to detect the resulting annihilation radiation. The internal pair production branching ratio determined from these measurements, (32.0 ± 1.5) × 10^-6 (k = 1), agrees within 1 standard uncertainty with the recommended value of (32.6 ± 0.7) × 10^-6 (k = 1) from the DDEP database.

Sleep quality is associated with vasopressin methylation in pregnant and postpartum women with a history of psychosocial stress

BACKGROUND

The relationship between disturbed sleep and stress is well-documented. Sleep disorders and stress are highly prevalent during the perinatal period, and both are known to contribute to a number of adverse maternal and foetal outcomes. Arginine vasopressin (AVP) is a hormone and a neuropeptide that is involved in stress response, social bonding and circadian regulation of the sleep-wake cycle. Whether the AVP system is involved in regulation of stress response and sleep quality in the context of the perinatal mental health is currently unknown. The objective of the present study was to assess the relationship between levels of cumulative and ongoing psychosocial risk, levels of disordered sleep and AVP methylation in a community sample of pregnant and postpartum women.

METHODS

A sample of 316 participants completed a battery of questionnaires during the second trimester of pregnancy (PN2, 12-14 weeks gestation), third trimester (PN3, 32-34 weeks gestation), and at 7-9 weeks postpartum (PP). Disordered sleep was measured using the Sleep Symptom Checklist at PN2, PN3 and PP; cumulative psychosocial risk was assessed with the Antenatal Risk Questionnaire (ANRQ) at PN2; salivary DNA was collected at the follow-up (FU, 2.9 years postpartum); and % methylation were calculated for AVP and for two of the three AVP receptor genes (AVPR1a and AVPR1b). Women were separated into high (HighPR) and low (LowPR) psychosocial risk groups, based on their scores on the ANRQ.

RESULTS

Women in the HighPR group had significantly worse sleep disturbances during PN2 (p < .001) and PN3 (p < .001), but not at PP (p = .146) than women in the LowPR group. In HighPR participants only, methylation of AVP at intron 1 negatively correlated with sleep disturbances at PN2 (r_s=-.390, p = .001), PN3 (r_s=-.384, p = .002) and at PP (r_s= -.269, p = .032). There was no association between sleep disturbances and AVPR1a or AVPR1b methylation, or between sleep disturbances and any of the AVP methylation for the LowPR group. Lastly, cumulative psychosocial stress was a moderator for the relationship between AVP intron 1 methylation and disordered sleep at PN2 (p < .001, adjusted R² = .105), PN2 (p < .001, adjusted R² = .088) and PP (p = .003, adjusted R² = .064).

CONCLUSIONS

Our results suggest that cumulative psychosocial stress exacerbates sleep disorders in pregnant women, and that salivary DNA methylation patterns of the AVP gene may be seen as a marker of biological predisposition to stress and sleep reactivity during the perinatal period. Further research is needed to establish causal links between AVP methylation, sleep and stress.

Image reconstruction in cardiovascular CT: Part 2 - Iterative reconstruction; potential and pitfalls

The use of IR in CT previously has been prohibitively complicated and time consuming, however improvements in computer processing power now make it possible on almost all CT scanners. Due to its potential to allow scanning at lower doses, IR has received a lot of attention in the medical literature and has become a successful commercial product. Its use in cardiovascular CT has been driven in part due to concerns about radiation dose and image quality. This manuscript discusses the various vendor permutations of iterative reconstruction (IR) in detail and critically appraises the current clinical research available on the various IR techniques used in cardiovascular CT.

Abstract P3-07-06: Evidence for tumor heterogeneity and clonal evolution during invasive progression in breast cancer

Purpose: Intratumoral heterogeneity is well recognized to be an important driver of treatment resistance and metastasis. We undertook this N of three study to measure the degree of heterogeneity in three large preinvasive lesions, all with invasive components to determine the relationship between tumor heterogeneity, spatial distribution, clonal evolution, and invasive progression.

Methods: We identified patients A, B, C with extensive DCIS measuring 7.5 cm, 6 cm, and 7 cm associated with 0.3 cm, 3.8cm, and 3.4 cm of an invasive component and 0, 7 and 1 positive lymph node, respectively. We sequenced the tumor sample for Case A from 32 unique blocks with precise geospatial localization; invasive cancer was identified in 3 of 32 blocks. Case B had 26 blocks sequenced with invasive cancer in 13 of 26 blocks. Case C had 23 blocks sequenced with invasive in 11 of 23 blocks. For germline reference, we sequenced DNA from an uninvolved tissue from each case. NGS libraries were made from FFPE derived DNA (20-40ng) for full exome sequencing. Variant calling was performed by GATK HaplotypeCaller, Platypus and Mutect. Identified somatic mutations were annotated with Oncotator and pathway enrichment analysis was performed with Bioconductor. To investigate the clonal evolution and progression history, phylogenetic trees were constructed in R and sub-clonal analysis was performed with Treeomics.

Results: The sequence data was analyzed with Platypus, MuTect and GATK HaplotypeCaller. The somatic mutation sites were concatenated into one sequence for each sample. Both neighbor-joining trees and maximum parsimony trees were built for each case. Phylogenetic analysis and sub-clonal analysis support the multi-clonal invasion model of invasive cells, in which invasive cancer can evolve from multiple clades, either early or late in the evolutionary history, independently. Dense sampling allowed reconstruction of the temporal order of mutations that accumulated in the cell lineage of the invasive cancers. Furthermore, phylogeny and sub-clone spatial analysis revealed that distant regions may be closely genetically related and showed a weak spatial sub-clone clustering pattern, which is consistent with the predictions of Big Bang model. For driver genes, we find that except for SETD2 in Case B, the majority of driver gene mutations are sub-clonal. Somatic mutations on ATP-binding cassette (ABC) transporter pathway was found in all cases.

Conclusions: Extensive sampling and sequencing of tumors yields important insights about tumor heterogeneity and tumor progression of DCIS to invasive cancer. Variable invasive propensity was identified, with foci of invasion were geospatially associated with preinvasive regions of progressively higher mutational load.

The relationship between sense of coherence and post-traumatic stress: a meta-analysis

Background: Antonovsky's concept of sense of coherence (SOC) - as a global orientation reflecting an individual's feeling of confidence in both the predictability of their internal and external environment and their ability to cope with stressful and challenging situations in life - shows a negative association with symptoms of post-traumatic stress. However, single studies varying in study characteristics provide heterogeneous effect size estimations. Objective: The purpose of the current study is to investigate the relationship between SOC and post-traumatic stress disorder (PTSD) symptom severity for the first time on a meta-analytical level. Method: The random-effects meta-analysis is based on zero-order correlations (r) and consists of 47 independent samples out of 45 studies (N = 10,883). Results: After correcting for sampling error, the mean correlation between SOC and PTSD symptoms was M(r) = -.41 (excluding four outliers: -.39). However, this effect could not be generalized to all types of PTSD samples owing to substantial remaining heterogeneity. Subsequent moderator analyses investigating the influence of different SOC and PTSD measures, trauma type and duration, mean age and gender imbalances per sample did not reveal significant moderating effects. Conclusions: The meta-analysis reveals a substantial correlation between SOC and PTSD symptom severity: higher SOC levels are associated with lower symptom severity. Thus, future research should progress to the question of whether the relationship between SOC and post-traumatic stress is causal, and by which factors it is moderated.

In inpatient rehabilitation, large amounts of practice can occur safely without direct therapist supervision: an observational study

QUESTIONS

When a hospital gymnasium used for inpatient rehabilitation is set up to allow semi-supervised practice: what percentage of practice is performed as semi-supervised practice, what percentage of patients in the gym are actively engaged in practice at one time, and is the semi-supervised practice that occurs safe?

DESIGN

An observational study using periodic behaviour mapping.

PARTICIPANTS

Patients in general and stroke rehabilitation units of a metropolitan hospital.

OUTCOME MEASURES

Observations in the rehabilitation gym quantified the number of patients in the gym and the numbers of patients practising and resting. In observations of patients practising, the condition of practice was recorded as being with a therapist, with a family member, or with no direct supervision. The number of adverse events during the data collection period was collected from the hospital Incident Information Management System.

RESULTS

The rehabilitation gym was observed on 113 occasions, resulting in 1319 individual patient observations. An average of 12 patients were in the gym during the observations. Practice was being performed with family supervision in 15% of observations and with no direct supervision in 26% of observations, resulting in semi-supervised practice accounting for 41% of all observations of practice. The percentage of observations that were of patients taking part in active practice was 78%. There were no adverse events in the gym.

CONCLUSION

In an inpatient setting, a large percentage of practice can be performed as semi-supervised practice. This does not appear to compromise the time spent in active practice or patient safety.

Time to look past TNF and thalidomide for cachexia - could mast cells and flavonoids be the answer?

Cachexia is a wasting condition associated with late stages of many chronic illnesses and may be present in up to 80% of patients with advanced cancers. Cachexia is a metabolic derangement resulting in a disturbance to the homeostasis of muscle breakdown and synthesis, favoring catabolism and muscle loss. Despite making strides in treating cancer itself, there have been no major advances in the treatment of cachexia pharmacologically or nutritionally. Clinical trials using anti-TNF biologics and thalidomide have largely failed. A new approach may be to focus on other possible waste-inducing mediators, possibly derived from mast cells, and the beneficial action of select natural flavonoids.

Improving disease knowledge in 6- to 10-year-olds with sickle cell disease: A quasi-experimental study

BACKGROUND

Increasing knowledge and understanding of disease is known to improve outcomes in persons living with a chronic illness. In this paper, we aim to compare the disease knowledge of children with sickle cell disease (SCD), age 6-10 years, who received an intervention (an educational colouring book on SCD) geared towards improving disease knowledge, to those who did not received the colouring book.

METHODS

A quasi-experimental study was conducted where disease knowledge was determined in 56 children who had received the colouring book and compared to 60 children who did not receive this intervention.

RESULTS

The mean knowledge score was significantly higher in the intervention group (mean difference = 2.65; 95% CI [1.43, 3.86]), as well as in older children and in those in higher grades but there was no difference between sexes. In a multiple regression model (adjusted R² : 0.39; p value < .001), knowledge score was significantly higher in those who received the intervention (β: 2.62; 95% CI [1.48, 3.76]) while adjusting for age, gender, persons living at home, and the father's employment status.

CONCLUSION

The study highlights that a simple, inexpensive (cost: US$1/book) child-friendly intervention can significantly improve knowledge about SCD even in young children. It also underlines various social factors that are associated with children's understanding of their disease.
