Equitable inclusion of diverse populations in oncology clinical trials: deterrents and drivers

The burden of cancer exerts a disproportionate impact across different regions and population subsets. Disease-specific attributes, coupled with genetic and socioeconomic factors, significantly influence cancer treatment outcomes. Precision oncology promises the development of safe and effective options for specific ethnic phenotypes and clinicodemographic profiles. Currently, clinical trials are concentrated in resource-rich geographies with younger, healthier, white, educated, and empowered populations. Vulnerable and marginalized people are often deprived of opportunities to participate in clinical trials. Despite consistent endeavors by regulators, industry, and other stakeholders, factors including diversity in trial regulations and patient and provider-related cultural, logistic, and operational barriers limit the inclusiveness of clinical trials. Understanding and addressing these constraints by collaborative actions involving regulatory initiatives, industry, patient advocacy groups, community engagement in a culturally sensitive manner, and designing and promoting decentralized clinical trials are vital to establishing a clinical research ecosystem that promotes equity in the representation of population subgroups.

Temporal dynamics of the multi-omic response to endurance exercise training

Regular exercise promotes whole-body health and prevents disease, but the underlying molecular mechanisms are incompletely understood1-3. Here, the Molecular Transducers of Physical Activity Consortium4 profiled the temporal transcriptome, proteome, metabolome, lipidome, phosphoproteome, acetylproteome, ubiquitylproteome, epigenome and immunome in whole blood, plasma and 18 solid tissues in male and female Rattus norvegicus over eight weeks of endurance exercise training. The resulting data compendium encompasses 9,466 assays across 19 tissues, 25 molecular platforms and 4 training time points. Thousands of shared and tissue-specific molecular alterations were identified, with sex differences found in multiple tissues. Temporal multi-omic and multi-tissue analyses revealed expansive biological insights into the adaptive responses to endurance training, including widespread regulation of immune, metabolic, stress response and mitochondrial pathways. Many changes were relevant to human health, including non-alcoholic fatty liver disease, inflammatory bowel disease, cardiovascular health and tissue injury and recovery. The data and analyses presented in this study will serve as valuable resources for understanding and exploring the multi-tissue molecular effects of endurance training and are provided in a public repository ( https://motrpac-data.org/ ).

A retrospective multicentre clinical study on management of isolated splenic vein thrombosis: risks and benefits of anticoagulation

INTRODUCTION

Isolated splenic vein thrombosis (iSVT) is a common complication of pancreatic disease. Whilst patients remain asymptomatic, there is a risk of sinistral portal hypertension and subsequent bleeding from gastric varices if recanalisation does not occur. There is wide variation of iSVT treatment, even within single centres. We report outcomes of iSVT from tertiary referral hepatobiliary and pancreatic (HPB) units including the impact of anticoagulation on recanalisation rates and subsequent variceal bleeding risk.

METHODS

A retrospective cohort study including all patients diagnosed with iSVT on contrast-enhanced CT scan abdomen and pelvis between 2011 and 2019 from two institutions. Patients with both SVT and portal vein thrombosis at diagnosis and isolated splenic vein thrombosis secondary to malignancy were excluded. The outcomes of anticoagulation, recanalisation rates, risk of bleeding and progression to portal vein thrombosis were examined using CT scan abdomen and pelvis with contrast.

RESULTS

Ninety-eight patients with iSVT were included, of which 39 patients received anticoagulation (40%). The most common cause of iSVT was acute pancreatitis n = 88 (90%). The recanalisation rate in the anticoagulation group was 46% vs 15% in patients receiving no anticoagulation (p = 0.0008, OR = 4.7, 95% CI 1.775 to 11.72). Upper abdominal vascular collaterals (demonstrated on CT scan angiography) were significantly less amongst patients who received anticoagulation treatment (p = 0.03, OR = 0.4, 95% CI 0.1736 to 0.9288). The overall rate of upper GI variceal-related bleeding was 3% (n = 3/98) and it was independent of anticoagulation treatment. Two of the patients received therapeutic anticoagulation.

CONCLUSION

The current data supports that therapeutic anticoagulation is associated with a statistically significant increase in recanalisation rates of the splenic vein, with a subsequent reduction in radiological left-sided portal hypertension. However, all patients had a very low risk of variceal bleeding regardless of anticoagulation. The findings from this retrospective study should merit further investigation in large-scale randomised clinical trials.

Limitations of antifungal prophylaxis in preventing invasive Candida surgical site infections after liver transplant surgery

Invasive primary Candida surgical site infections (IP-SSIs) are a common complication of liver transplantation, and targeted antifungal prophylaxis is an efficient strategy to limit their occurrence. We performed a retrospective single-center cohort study among adult single liver transplant recipients at Duke University Hospital in the period between 1 January 2015 and 31 December 2020. The study aimed to determine the rate of Candida IP-SSI according to the peri-transplant antifungal prophylaxis received. Of 470 adult single liver transplant recipients, 53 (11.3%) received micafungin prophylaxis, 100 (21.3%) received fluconazole prophylaxis, and 317 (67.4%) did not receive systemic antifungal prophylaxis in the peri-transplant period. Ten Candida IP-SSIs occurred among 5 of 53 (9.4%) micafungin recipients, 1 of 100 (1.0%) fluconazole recipients, and 4 of 317 (1.3%) recipients who did not receive antifungal prophylaxis. Our study highlights the limitations of antifungal prophylaxis in preventing invasive Candida IP-SSI after liver transplant surgery. We hypothesize that pathogen, host, and pharmacokinetic-related factors contributed to the occurrence of Candida IP-SSI despite antifungal prophylaxis. Our study reinforces the need for a risk-based, multi-pronged approach to fungal prevention, including targeted antifungal administration in patients with risks for invasive candidiasis and close monitoring, especially among patients with surgically complex procedures, with timely control of surgical leaks.

Identifying barriers and facilitators to care for infants with bronchopulmonary dysplasia after NICU discharge: a prospective study of parents and clinical stakeholders

OBJECTIVE

Understand barriers and facilitators to follow-up care for infants with bronchopulmonary dysplasia (BPD).

METHODS

Qualitative study of parents and clinical stakeholders caring for infants with BPD. The interview guide was developed by a mother of a former 23-week preterm infant, neonatologist, pulmonologist, nurse, and qualitative researcher. Purposive sampling obtained a heterogenous sociodemographic and professional cohort. Subjects discussed their experience with BPD, barriers to care, caregiver quality of life and health education. Interviews were audio-recorded, transcribed and coded. Thematic analysis was used.

RESULTS

Eighteen parents and 20 stakeholders completed interviews. Family-level themes included pragmatic barriers like transportation being multi-faceted; and caregiving demands straining mental health. System-level themes included caregiver education needing to balance immediate caregiving activities with future health outcomes; and integrating primary care, specialty, and community supports.

CONCLUSIONS

Individual and system barriers impact follow-up for infants with BPD. This conceptual framework can be used to measure and improve care.

Pessary management practices for pelvic organ prolapse among Australian health care practitioners: a cross-sectional study

INTRODUCTION AND HYPOTHESIS

Vaginal pessaries are a low-cost, effective treatment for pelvic organ prolapse (POP) and an alternative to surgery. Whilst traditionally pessary management (PM) has been provided by medical professionals, particularly gynaecologists, recent international studies found other professionals, including physiotherapists and nurses, may be involved. It is unknown which health care practitioners (HCPs) provide PM for POP in Australia or the distribution of services.

METHODS

In a cross-sectional study design, a self-reported electronic survey investigated Australian HCPs providing PM for POP. Purposive and snowball sampling targeted HCPs, professional organisations and health care facilities. Descriptive statistics described PM in relation to HCP professional profile, PM provision and geographical location.

RESULTS

There were 536 respondents (324 physiotherapists, 148 specialists, 33 general practitioners (GPs) and 31 nurses providing PM. Most worked within metropolitan regions (n = 332, 64%), 140 (27%) in rural, 108 (21%) in regional and 10 (2%) in remote areas. Most worked privately (n = 418, 85%), 153 (46%) worked publicly and 85 (17%) in both. Ring pessaries were most commonly used, followed by cube and Gellhorn. HCPs reported variable training in PM, and 336 (69%) had no mandatory workplace competency standard; however, 324 (67%) wanted further training. Women travelled long distances to access services.

CONCLUSIONS

Doctors, nurses and physiotherapists provided PM in Australia. HCPs had variable training and experience in PM, with rural and remote HCPs particularly wanting further training. This study highlights the need for accessible PM services, standardised and competency-based training for HCPs, and governance structures ensuring safe care.

A new portable field rotational viscometer for high-temperature melts

Mounted on top of furnaces, laboratory viscometers can be used for the rheological characterization of high temperature melts, such as molten rocks (lava). However, there are no instruments capable of measuring the viscosity of large volumes of high temperature melts outside the laboratory at, for example, active lava flows on volcanoes or at industrial sites. In this article, we describe a new instrument designed to be easy to operate, highly mobile, and capable of measuring the viscosity of high temperature liquids and suspensions (<1350 °C). The device consists of a torque sensor mounted in line with a stainless-steel shear vane that is immersed in the melt and driven by a motor that rotates the shear vane. In addition, a thermocouple placed between the blades of the shear vane measures the temperature of the melt at the measurement location. An onboard microcomputer records torque, rotation rate, and temperature simultaneously and in real time, thus enabling the characterization of the rheological flow curve of the material as a function of temperature and strain rate. The instrument is calibrated using viscosity standards at low temperatures (20-60 °C) and over a wide range of stress (30-3870 Pa), strain rate (0.1-27.9 s-1), and viscosity (10-650 Pa s). High temperature tests were performed in large scale experiments within ∼25 l of lava at temperatures between 1000 and 1350 °C to validate the system's performance for future use in natural lava flows. This portable field viscometer was primarily designed to measure the viscosity of geological melts at their relevant temperatures and in their natural state on the flanks of volcanoes, but it could also be used for industrial purposes and beyond.

The Influence of Racism in Healthcare: COVID-19 Vaccine Hesitancy Among Black Mothers in Chicago

Black mothers and children experience significant health disparities in the USA. These health disparities have been attributed, in part, to experiencing racism in healthcare. This study aimed to explore how experiences of healthcare discrimination and mistreatment experienced by Black mothers may influence COVID-19 vaccine beliefs and decision-making for themselves and their families. From April 2021 to November 2021, we conducted 50 semi-structured interviews among Chicago residents. Ten participants self-identified as female and with reported children; these data were extracted from the larger sample for data analysis. Interview content included perceptions and experiences with the COVID-19 vaccine and experiences with healthcare discrimination, mistreatment, and medical mistrust. Interview transcripts were transcribed verbatim and coded using the MAXQDA 2022 qualitative software. Themes were identified using a team-based thematic analysis to understand how experiences of racism in healthcare may influence COVID-19 vaccine decision-making. Four themes were generated from the data: (1) experiences of healthcare discrimination and mistreatment, (2) distrust and fears of experimentation, (3) the influence of discrimination and distrust on COVID-19 vaccine decision-making, and (4) overcoming vaccine hesitancy. The results of this study highlight the current literature; Black mothers experience racism and discrimination in healthcare when seeking care for themselves and their children. It is evident in their stories that medical racism and historical medical abuse influence vaccine decision-making. Therefore, healthcare and public health initiatives should be intentional in addressing past and present racism in healthcare to improve vaccine distrust.

The COVID-19, racism, and violence syndemic: Evidence from a qualitative study with Black residents of Chicago

The COVID-19 pandemic emerged in the United States in the shadows of a vast history of structural racism and community and police violence that disproportionately affect Black communities. Collectively, they have created a syndemic, wherein COVID-19, racism, and violence are mutually reinforcing to produce adverse health outcomes. The purpose of this study was to understand the COVID-19, racism, and violence syndemic and examine how structural racism and violence contributed to the disproportionate impact of COVID-19 on Black communities. In early 2021, we conducted phenomenological qualitative interviews with 50 Black residents of Chicago. Interview transcripts were coded and analyzed using thematic analysis. We identified four primary themes in our analyses: 1) the intersection of racism and violence in Chicago; 2) longstanding inequities were laid bare by COVID-19; 3) the pervasiveness of racism and violence contributes to poor mental health; 4) and COVID-19, racism and violence emerged as a syndemic. Our findings underscore the importance of addressing social and structural factors in remediating the health and social consequences brought about by COVID-19.

Comparative Effectiveness of Integrated Peer Support and Clinical Staffing Models for Community-Based Residential Mental Health Rehabilitation: A Prospective Observational Study

This observational study compared the outcomes of consumers receiving community-based residential mental health rehabilitation support in Australia under a clinical staffing model and an integrated staffing model where Peer Support Workers are the majority component of the staffing profile. Reliable and clinically significant (RCS) change between admission and discharge in functional and clinical assessment measures were compared for consumers receiving care under the clinical (n = 52) and integrated (n = 93) staffing models. Covariate analyses examined the impact of known confounders on the outcomes of the staffing model groups. No statistically significant differences in RCS improvement were identified between the staffing models. However, logistic regression modelling showed that consumers admitted under the integrated staffing model were more likely to experience reliable improvement in general psychiatric symptoms and social functioning. The findings support the clinical and integrated staffing models achieving at least equivalent outcomes for community-based residential rehabilitation services consumers.

A68 HOW REAL ARE YOUR SURVEY RESPONDENTS? IDENTIFYING FRAUDULENT RESPONDENTS IN ONLINE SURVEYS – A CASE EXAMPLE IN INFLAMMATORY BOWEL DISEASE (IBD)

Background

Social media and online surveys are commonly used to recruit and collect data from patients and physicians about GI diseases – they are efficient, convenient, and less resource intensive compared to traditional recruitment approaches and paper surveys. However, online data fraud is increasing and difficult to identify. Online data fraud can include intentional duplicate responses/straight-lining/inattention, bots/malicious software, and professional survey takers who provide fraudulent responses to meet study eligibility.

Purpose

1) Illustrate challenges of identifying fraudulent respondents through an algorithm and verification process we developed for our survey in IBD. 2) Demonstrate potential impact of fraudulent respondents on data and results.

Method

Online survey of Canadian adults (>18 years) with IBD about healthcare processes for managing IBD hosted using Qualtrics. Recruitment was done in clinic and online (mailing lists, social media). A $25 giftcard was offered for participation due to low response after 3 months in field, after which a large influx of ‘respondents’ occurred. Most were fraudulent although not obvious at first. To mitigate further fraudulent responses, we added the following to our survey: reCAPTCHA score, repeated question (year of IBD diagnosis), duplicate ID score, fraud score and honeypot question.

Our algorithm to identify fraudulent responses included 13 binary ‘red flag’ variables: age <18 years, year of diagnosis < year of birth, 2 different year of diagnosis, invalid postal code, survey duration <10 minutes, survey duration 10-15 minutes, suspicious comments for open text questions (x2), duplicate email, suspicious email, duplicate ID score ≥30, fraud score ≥30, and failed honeypot question. These variables were used to generate a fraudulent response score (range: 0-13; 13=most likely fraudulent). ‘Respondents’ with scores >3 were categorized as likely fraudulent. Respondents with scores ≤3 were reviewed individually. Respondents flagged as likely real or unsure were emailed and asked to verify their age; those who correctly verified age were considered likely real and included in the final sample.

Result(s)

Of the 4334 ‘respondents’ who started the survey, based on fraudulent response score we identified 75% (n=3258) as likely fraudulent, 17% (n=727) as unsure and 8% (n=349) as likely real. After age verification, 76% (n=3297) were considered likely fraudulent, 14% (n=592) remained unsure, 10% (n=442) were considered likely real, and <1% (n=3) were duplicates of likely real respondents.

Conclusion(s)

Despite convenience, social media and online surveys can be prone to fraudulent responses, especially when incentives are offered. We developed an algorithm and verification process to identify fraudulent responses using an IBD survey example. Given that only 10% of the full sample was considered likely real, researchers using social media and online surveys should carefully examine data for fraudulent responses and apply strategies to mitigate risks.

Racial/ethnic differences in social determinants of health and health outcomes among adolescents and youth ages 10-24 years old: a scoping review

INTRODUCTION

With the recent emergence of the Healthy People 2030 goals there is a need to understand the role of SDOH on health inequalities from an upstream perspective. This review summarizes the recent body of evidence on the impact of SDOH across adolescence and youth health outcomes by race/ethnicity using the Health People 2030 Framework.

METHODS

A systematic, reproducible search was performed using PubMed, Academic Search Premier, PsychInfo, and ERIC. A total of 2078 articles were screened for inclusion. A total of 263 articles met inclusion criteria, resulting in 29 articles included for final synthesis.

RESULTS

Across the 29 articles, 11 were cross-sectional, 16 were cohort, and 2 were experimental. Across SDOH categories (economic stability, education access and quality, health care access and quality, neighborhood and built environment, and social and community context), 1 study examined self-efficacy, 6 educational attainment, 10 behavior, 5 smoking, 11 alcohol use, 10 substance use, and 1 quality of life. The majority of outcomes represented in this search included health behaviors such as health risk behavior, smoking, alcohol use, and substance use. Across the 29 articles identified, significant differences existed across outcomes by race/ethnicity across SDOH factors, however magnitude of differences varied by SDOH category.

DISCUSSION

SDOH differentially affect adolescents and youth across race/ethnicity. The lived adverse experiences, along with structural racism, increase the likelihood of adolescents and youth engaging in risky health behaviors and negatively influencing health outcomes during adolescence and youth. Research, public health initiatives, and policies integrating SDOH into interventions at early stage of life are needed to effectively reduce social and health inequalities at a population level.

Effect of exogenous testosterone in the context of energy deficit on risky choice: Behavioural and neural evidence from males

Previous research has shown greater risk aversion when people make choices about lives than cash. We tested the hypothesis that compared to placebo, exogenous testosterone administration would lead to riskier choices about cash than lives, given testosterone's association with financial risk-taking and reward sensitivity. A double-blind, placebo-controlled, randomized trial was conducted to test this hypothesis (Clinical Trials Registry: NCT02734238, www.clinicaltrials.gov). We collected functional magnetic resonance imaging (fMRI) data from 50 non-obese males before and shortly after 28 days of severe exercise-and-diet-induced energy deficit, during which testosterone (200 mg testosterone enanthate per week in sesame oil) or placebo (sesame seed oil only) was administered. Because we expected circulating testosterone levels to be reduced due to severe energy deficit, testosterone administration served a restorative function to mitigate the impact of energy deficit on testosterone levels. The fMRI task involved making choices under uncertainty for lives and cash. We also manipulated whether the outcomes were presented as gains or losses. Consistent with prospect theory, we observed the reflection effect such that participants were more risk averse when outcomes were presented as gains than losses. Brain activation in the thalamus covaried with individual differences in exhibiting the reflection effect. Testosterone did not impact choice, but it increased sensitivity to negative feedback following risky choices. These results suggest that exogenous testosterone administration in the context of energy deficit can impact some aspects of risky choice, and that individual differences in the reflection effect engage a brain structure involved in processing emotion, reward and risk.

HEALTH EXP ERIENCES OF SEXUAL AND GENDER MINORITY PEOPLE LIVING WITH DEMENTIA AND THEIR CAREGIVERS: A SCOPING REVIEW

People living with dementia and older adults who identify as sexual and gender minority (SGM - lesbian, gay, bisexual, transgender, queer individuals) both represent minoritized groups of older adults, but little is known about the health experiences of older adults who are at the intersection of having dementia and also identify as SGM. This review explored the extent and nature of research focused on health and healthcare experiences of SGM people with dementia and/or their informal caregivers. A scoping review framework was used given the exploratory nature of the project’s purpose. Health librarians comprehensively searched four databases (MEDLINE, CINAHL, PsycINFO, AgeLine) to identify relevant studies. A total of 8,137 unique titles and abstracts were reviewed by 2 independent reviewers. Forty citations were determined relevant and reviewed by full text. Eight studies met inclusion criteria and were analyzed thematically. Study methods were quantitative cross-sectional (n=2), qualitative exploratory (n=4), and a mixed methods case study (n=1). Studies were published from 2010–2022. Sample sizes ranged from 1 to 415 (M=113, SD=116). Four studies focused on caregivers, 2 on persons with dementia, and 1 on dyads. Themes emerged pertaining to caregiver health and well-being, identity, relationships, disclosure, discrimination, and safety. Findings highlight the significance of inclusive care that addresses intersecting psychosocial and health-related identities (e.g., cognitive status, SGM status, race/ethnicity, substance abuse history, multimorbidity) and that protects the rights of families of choice. More research is needed to better understand how sociopolitical structure influences dynamics between cognitive health and SGM status among older adults.

ACCEPTABILITY OF ANIMATRONIC PETS AMONG COMMUNITY-DWELLING VETERANS LIVING WITH DEMENTIA AND THEIR CAREGIVERS

Animatronic pets can improve psychosocial outcomes among older adults, but little is known about in-home use by Veterans living with dementia and the perceptions of informal caregivers regarding these tools. This quality improvement project examined the usability and acceptability of animatronic pets by community dwelling Veterans living with dementia from the perspective of informal caregivers. Usability and acceptability were examined through a structured telephone interview with 17 caregivers. Usability was operationalized as frequency of: pet use by the Veteran (1=Not at all, 4=Daily or all of the time), and reminders provided by caregivers (1=Not at all, 4=Daily or all of the time). Acceptability was defined as perceived benefit (measured using an acceptability tool; 0= Not at all, 2=A great deal beneficial) and satisfaction (measured using acceptability tool with close and open-ended response items) as reported by caregivers. Results indicated high usability (71% of Veterans used the pet daily with reminders provided by 30% of caregivers) and acceptability (Benefit: (M=1.5/2, SD=0.7); Satisfaction: 94% of caregivers would continue to encourage use of the animatronic pet by the Veteran and recommend one to others). Open-ended responses suggest that they may be less satisfying to those who lost a real pet or did not have an affinity for pets earlier in life. Animatronic pets can be used with minimal assistance by Veterans with dementia and are acceptable to informal caregivers. As VA initiatives support provision of these pets, additional research is needed to examine their broader impact on Veterans living with dementia specifically.

The human right to safely give birth: data from 193 countries show that gender equality does affect maternal mortality

BACKGROUND

While a reduction in the global maternal mortality ratio (MMR) has slowed, newer strategies are needed to achieve an ongoing and sustainable reduction of the MMR. Previous studies have investigated the association between health system-related factors such as wealth inequalities, healthcare access and use on maternal mortality. However, a women's rights-based approach to address MMR has not been studied, excluding the health system-related factors. This study aimed to analyse the association between gender equality and MMR globally.

METHODS

Using structural equation modelling (SEM), secondary and open access data from the United Nations and other international agencies from 193 countries were analysed using structural equation modelling (SEM). Gender-sensitive variables that represented the theoretical, conceptual framework of the study were selected. The association between latent variable gender equality and the outcome, MMR, was examined in the SEM. A second SEM model (n = 158) was designed to include two variables related to gender-based violence.

FINDINGS

The latent variable, gender equality, was negatively associated with MMR (p < 0‧001, Z = -6‧96, 95% CI: - 6508.98 to - 3141.89 for Model 1 and p < 0‧001, Z = -7‧23, 95% CI: - 6045.356 to - 3467.515 for Model 2).

INTERPRETATION

Gender equality was significantly associated with maternal mortality. Investing in higher education for women, improving their paid employment opportunities, increasing participation in leadership roles and politics, reducing intimate partner violence (IPV) and ending child marriage can significantly reduce maternal mortality.

Transitions from pediatric to adult rheumatology care for juvenile idiopathic arthritis: a patient led qualitative study

Background

Juvenile idiopathic arthritis (JIA) is a childhood autoimmune disease that causes swelling and pain in at least one joint. Young people with JIA experience symptoms that persist into adulthood, and thus will undergo a transition including the o transfer of care from a pediatric rheumatologist an adult rheumatologist. Missing from the literature is research that centres the transition experience of young people with JIA in Canada. This goal of this patient-led research was to explore the experience young people with JIA through the process of transition.

Methods

Qualitative study using the Patient and Community Engaged Research (PaCER) approach. Trained patient-researchers conducted three focus groups using the Set, Collect and Reflect PaCER process. Participants, recruited via purposive and snowball sampling using research/personal networks and social media, were young people with JIA in Canada between 18 and 28 years who had experienced with the process of transition to adult care. Recordings were transcribed verbatim. Patient researchers individually coded overlapping sections of the data, and thematic analysis was conducted.

Results

In total, nine individuals participated in one or more focus groups. Three themes were identified, with sub-themes: preparedness for transition (readiness for the transfer of care, developing self-advocacy skills), continuity and breadth of care (changing relationships, culture shock, new responsibilities), need for support (social support, mental health support, and ongoing support needs – beyond the transfer of care. Peer support was a connecting concept in the support sub-themes. Transition was more than a change in primary physician but also a change in the care model and breadth of care provided, which was challenging for young people especially if they had insufficient information.

Conclusions

Transition from pediatric to adult care in rheumatology is a significant period for young people living with JIA, and this patient-led study provided insight into the experience from the perspective of young people with JIA which is critical to informing the development of supports for patients through the process. Patients, caregivers, pediatric and adult rheumatologists and members of the multi-disciplinary care team need to collaborate in terms of resources preparing for transfer, and support throughout the transition process to ensure a successful transition process.

Time to dementia diagnosis by race: A retrospective cohort study

BACKGROUND

Non-Hispanic Black individuals may be less likely to receive a diagnosis of dementia compared to non-Hispanic White individuals. These findings raise important questions regarding which factors may explain this observed association and any differences in the time to which disparities emerge following dementia onset.

METHODS

We conducted a retrospective cohort study using survey data from the 1995 to 2016 Health and Retirement Study linked with Medicare fee-for-service claims. Using the Hurd algorithm (a regression-based approach), we identified dementia onset among older adult respondents (age ≥65 years) from the Telephone Interview for Cognitive Status and proxy respondents. We determined date from dementia onset to diagnosis using Medicare data up to 3 years following onset using a list of established diagnosis codes. Cox Proportional Hazards modeling was used to examine the association between an individual's reported race and likelihood of diagnosis after accounting for sociodemographic characteristics, income, education, functional status, and healthcare use.

RESULTS

We identified 3435 older adults who experienced a new onset of dementia. Among them, 30.1% received a diagnosis within 36 months of onset. In unadjusted analyses, the difference in cumulative proportion diagnosed by race continued to increase across time following onset, p-value <0.001. 23.8% of non-Hispanic Black versus 31.4% of non-Hispanic White participants were diagnosed within 36 months of dementia onset, Hazard Ratio = 0.73 (95% CI: 0.61, 0.88). The association persisted after adjustment for functional status and healthcare use; however, these factors had less of an impact on the strength of the association than income and level of education.

CONCLUSION

Lower diagnosis rates of dementia among non-Hispanic Black individuals persists after adjustment for sociodemographic characteristics, functional status, and healthcare use. Further understanding of barriers to diagnosis that may be related to social determinants of health is needed to improve dementia-related outcomes among non-Hispanic Black Americans.

A gamification-based intervention to encourage active travel

Purpose

‘Beat the Street’ is a community-wide intervention which aims to increase active travel by turning an area into a 6-week game. Residents earn points and prizes by walking and cycling and tapping a smartcard on RFID readers called ‘Beat Boxes’ placed on lampposts at half-mile intervals. To-date, over 1 million people have taken part in the intervention, however, the impact of the program on adult active travel is yet to be explored.

Methods

In Autumn 2019, Beat the Street was delivered throughout the London Borough of Hounslow. Prior, and immediately following the intervention, residents were invited to complete a self-report questionnaire (Sport England Active Lives Survey-SF) to assess changes in physical activity. Time-stamp data generated through Beat Box activity provided an objective measure of intervention engagement and a traffic survey camera was used to measure the number of cars travelling along 1 target road between 1-week pre- and 1-week post-intervention.

Results

28,219 people took part in the six-week game. Between pre- and post-intervention there was 7% decrease in adults reporting less than 30mins of activity per week and a 13% rise in adults reporting 150+ mins (n = 346, p &lt; 0.01). Beat box data ascertained that 25% of total taps at all Beat Boxes were made between 08:00-08:59am and a further 28% were made between 3:00-3:59pm, typical travel to school/work periods. Further, traffic camera data showed that between the week before and week following Beat the Street, 1199 and 705 fewer cars and 130 and 36 fewer vans were observed travelling along Cambridge Road between 07:00-09:30am and 2:00-4:30pm, respectively.

Conclusions

These data sources, in combination, suggest gamification may be an encouraging approach to increasing levels of active travel at a community-wide level.

Key messages

• Gamification based intervention increases physical activity.

• Gamification encourages active travel to school and work.

A Physical Activity Intervention in Older African Americans: The PAACE Pilot Randomized Controlled Trial

INTRODUCTION

Older African Americans have low levels of physical activity, which increases the risk of aging-related health conditions. This study aimed to determine the effectiveness of, and satisfaction with, a community-engaged physical activity intervention targeting older African Americans.

METHODS

Fifty-six older African Americans were randomized to a successful aging group (SAG) or a physical activity group (PAG) for 12 wk. The PAG consisted of two weekly group exercise sessions and two to three home-based exercise sessions per week. The SAG consisted of weekly group educational sessions related to various aspects of healthy aging. Physical activity was measured by ActiGraph accelerometers and the Community Healthy Activities Model Program for Seniors Activities Questionnaire in both groups, and a Fitbit was continuously worn by PAG participants.

RESULTS

Group session attendance was 93% and 86% in the PAG and SAG, respectively. The increase in ActiGraph-derived steps per day (1085.3 ± 265.6 vs 34.7 ± 274.3; P = 0.008) and daily minutes of moderate-to-vigorous physical activity (MVPA; 6.2 ± 1.6 vs 0.3 ± 1.7; d = 0.68; P = 0.01), and self-reported Community Healthy Activities Model Program for Seniors Activities Questionnaire MVPA bouts (3.5 ± 0.77 vs 0.33 ± 0.79; P < 0.001) were significantly greater within the PAG than the SAG. ActiGraph-derived minutes of daily MVPA and steps as well as Fitbit-derived steps per day were significantly greater on days when PAG participants engaged in group sessions compared with days when they self-reported home-based exercise or no exercise ( P < 0.016). Participants in both study arms reported high levels of satisfaction (>4- on 5-point Likert scale).

CONCLUSIONS

The intervention increased physical activity, was well attended, and resulted in high satisfaction. Future studies should assess long-term sustainability in this population.

Medicare spending associated with a dementia diagnosis among older adults

BACKGROUND

Over 6 million Americans have Alzheimer's Disease or Related Dementia (ADRD) but whether spikes in spending surrounding a new diagnosis reflect pre-diagnosis morbidity, diagnostic testing, or treatments for comorbidities is unknown.

METHODS

We used the 1998-2018 Health and Retirement Study and linked Medicare claims from older (≥65) adults to assess incremental quarterly spending changes just before versus just after a clinical diagnosis (diagnosis cohort, n = 2779) and, for comparative purposes, for a cohort screened as impaired based on the validated Telephone Interview for Cognitive Status (TICS) (impairment cohort, n = 2318). Models were adjusted for sociodemographic and health characteristics. Spending patterns were examined separately by sex, race, education, dual eligibility, and geography.

RESULTS

Among the diagnosis cohort, mean (SD) overall spending was $4773 ($9774) per quarter - 43% of which was spending on hospital care ($2048). In adjusted analyses, spending increased by $8400 (p < 0.001), or 156%, from $5394 in the quarter prior to $13,794 in the quarter including the diagnosis. Among the cohort in which impairment was incidentally detected using the TICS, adjusted spending did not change from just before to after detection of impairment, from $2986 before and $2962 after detection (p = 0.90). Incremental spending changes did not differ by sex, race, education, dual eligibility, or geography.

CONCLUSION

Large, transient spending increases accompany an ADRD diagnosis that may not be attributed to impairment or changes in functional status due to dementia. Further study may help reveal how treatment for comorbidities is associated with the clinical diagnosis of dementia, with potential implications for Medicare spending.

183 Improving Documentation of Antibiotic Prophylaxis and Anticoagulation in Vascular Surgery Operation Notes at a Tertiary Centre: A Quality Improvement Project

Aim

Operation notes have important medico-legal implications and should follow the Good Surgical Practice framework to enable continuity of care.

The aim of this quality improvement project was to determine adherence of vascular surgery operation notes to the Good Surgical Practice framework at a tertiary vascular centre, identify areas of improvement and introduce sustainable change to improve patient care.

Method

Two Plan-Do-Study-Act cycles were enacted. A prospective audit was conducted over September 2021 to identify areas of improvement in documentation. The first intervention that was introduced was electronic patient records (EPR). The second intervention introduced was departmental education via posters, regular educational sessions, and presentations.

Results

The prospective audit of 31 operations over September 2021 identified antibiotic prophylaxis was only recorded in 4/31 (13%) and post-operative anticoagulation in 21/31 (68%). A retrospective audit of 28 operations over October 2021 after the introduction of EPR demonstrated improved documentation of antibiotic prophylaxis (16/28, 57%) but no improvement in post-operative anticoagulation documentation (17/28, 61%). Departmental education improved the documentation of antibiotic prophylaxis (18/30, 60%) and post-operative anticoagulation (22/30, 73%).

Conclusions

We have demonstrated that EPR and departmental education can improve operation note documentation and patient care. Next steps include designing vascular surgery proformas to further improve documentation.

Exercise Effects on Cognition in Older African Americans: A Pilot Randomized Trial

Introduction

Regular physical activity lowers risk for cognitive decline and neurodegenerative disorders. Older African Americans (AAs) have been underrepresented in trials that increased physical activity to improve cognitive outcomes.

Methods

56 sedentary, older, cognitively healthy AAs (avg. 69.2 ± 3.4 yrs. old) were randomized in 1:1 ratio into either a 12-week successful aging group (SAG) or a 12-week physical activity group (PAG). Participants in SAG attended weekly 60-min educational sessions in which healthy aging topics were discussed. Participants in PAG attended supervised physical activity sessions twice per week at local YMCAs (90–120 min/week) and were prescribed 2–3 days per week of home-based activity. The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) assessed cognitive function. ANCOVA models compared mean 12-week change in global cognition and subdomain scores between groups with secondary analyses for sex differences. Effect sizes for RBANS were calculated.

Results

The RBANS global cognition score (SAG Est. 5.6 ± 1.8, effect size = 0.37, p = 0.003) and several subdomain scores (one-sample T tests, all p < 0.05) increased significantly within the SAG. Scores for global cognition increased more in SAG than in PAG (Change Estimate, PAG minus SAG: –4.6 ± 2.5 points, effect size = 0.31) at a trend level (p = 0.072). SAG females increased their global cognition score more than PAG females and more than males in either PAG or SAG (all p < 0.035).

Discussion

A 12-week physical activity intervention (PAG) did not improve cognitive functioning among older AAs but a comparator healthy aging education program did. Inadequate physical activity dosage or duration, SAG members acting on health-related information from educational sessions, and/or social stimulation within the SAG may have contributed to these results. Future studies should combine socially engaging activities with vigorous physical activity for cognitive enhancement among cognitively healthy older African Americans.

A Scalable, Weight Management Program Tailored for Adults with Type 2 Diabetes: Effects on Glycemic Control, Weight, Hunger, and Quality of Life

Objectives

Over 26 million people in the United States have type 2 diabetes (T2D) and 89% of those living with diabetes have overweight or obesity. Weight loss improves glycemic control and scalable weight management programs tailored for those living with diabetes are critically needed. The objective of this trial was to test the efficacy of a scalable and widely available diabetes-tailored weight management program (WW, formerly Weight Watchers) on glycemic control, weight, hunger, and quality of life (QOL) in adults with T2D and overweight/obesity.

Methods

This was a prospective 24-week single arm, three-site clinical trial. Participants (n = 136) had T2D, a baseline HbA1c between 7–11%, and a BMI between 27–50 kg/m². All participants received the 24-wk WW intervention, tailored for people with T2D, that included weekly virtual workshops and use of the WW App. Assessments occurred at baseline, wk 12 (83.8% retention), and wk 24 (83.1%). Change in HbA1c at 24 weeks was the primary outcome. Secondary outcomes were changes in body weight, hunger (assessed with visual analog scale), and quality of life (assessed with Impact of Weight on QOL-Lite) at 24-weeks. All analyses adhered to the intent-to-treat principle with maximum likelihood estimation used for missing data. Generalized linear effects models were used to examine change over time for all outcome variables.

Results

Participants were 56.8 ± 0.8 y (Mean ± SEM), 36.2 ± 0.6 kg/m², 80.2% Female, and 62.2% non-Hispanic white. Baseline HbA1c, weight, hunger, and IWQOL-Lite were 7.9 ± 0.1%, 104.3 ± 1.8 kg, 55 ± 2 units, and 76 ± 2 points, respectively. At week 24, HbA1c decreased by 0.8 ± 0.1%.and body weight decreased by 5.7 ± 0.5% (both p < .0001). A majority of participants achieved clinically significant weight loss, with 59.3% losing ≥3%, 42.5% losing ≥ 5%, and 15.0% losing ≥10% at 24-weeks. At 24 weeks, hunger decreased by 13.2% (p = 0.0125) and QOL improved by 13.6% (p < .0001), with significant improvements in the domains of physical function, self-esteem, sexual life, public distress, and work (all p-values < .05).

Conclusions

The widely available and scalable WW program, modified for those with T2D, had favorable and clinically meaningful effects on glycemic control, body weight, hunger, and quality of life.

Role of decentralized clinical trials in cancer drug development: Results from a survey of oncologists and patients

As a result of the unprecedented challenges imposed by the COVID-19 pandemic on enrollment to cancer clinical trials, there has been an urgency to identify and incorporate new solutions to mitigate these difficulties. The concept of decentralized or hybrid clinical trials has rapidly gained currency, given that it aims to reduce patient burden, increase patient enrollment and retention, and preserve quality of life, while also increasing the efficiency of trial logistics. Therefore, the clinical trial environment is moving toward remote collection and assessment of data, transitioning from the classic site-centric model to one that is more patient-centric.

App-based intervention for cardiovascular and diabetes risk awareness and prevention

Funding Acknowledgements

Type of funding sources: Public Institution(s). Main funding source(s): Centre for Primary Health Care and Equity, University of New South WalesAustralian e-Health Research Centre, Commonwealth Scientific and Industrial Research Organisation

Background

Cardiovascular disease and type 2 diabetes mellitus are highly prevalent worldwide. They have similar risk factors, and people with diabetes have a two- to threefold increased risk of myocardial infarction and stroke. Many of the risk factors are lifestyle related. Hence, behaviour change interventions have the potential to decrease the risk for cardiovascular disease and type 2 diabetes mellitus.

Purpose

We aimed to develop and evaluate an app-based intervention for the primary prevention of cardiovascular disease and type 2 diabetes mellitus.

Methods

We developed our app using the methodology by Tombor and colleagues for the development of digital behaviour change interventions. We used the Behaviour Change Wheel and embedded 12 behaviour change techniques. The three core modules of the app consisted of i) risk scores for 5-year cardiovascular disease and type 2 diabetes mellitus; ii) goal setting and tracking functions for smoking, alcohol intake, diet, and physical activity; and iii) education about the diseases and risk factors. With the app prototype, we conducted usability testing via an iterative approach. We interviewed the participants and used their feedback to improve the app design. Next, we conducted a feasibility study with the new version to assess whether participants would use the app over three months. We were interested in drop-out from the intervention, adherence to app use, and usability of the app. We received ethics approval for both studies and written consent from all participants.

Results

The usability testing consisted of two rounds. For each round, we had five participants who were on average 57 years old. In the first round, three participants experienced a technical error that stopped them from completing the registration. From those who were able to register, five rated the app as above average according to the System Usability Scale. Overall, the participants found the app easy to use and indicated that they were interested to use it frequently. We included some additional features based on the preferences of the participants in the usability testing. For the feasibility study, we recruited 47 participants aged 45 years and older who were free of cardiovascular disease and type 2 diabetes mellitus at baseline, with a balanced distribution of age (45-64 years and ≥65 years) and gender. From those participants, four withdrew from the study immediately after providing consent and the remainder continued using the app for varying periods of time.

Conclusions

We ensured that the app is based on the theory of behaviour change and scientific evidence. We used a stepwise approach to improve the app design and to test the feasibility of the intervention. The next step will be to develop a framework for a larger trial that implements the intervention into the existing healthcare setting and investigates its effectiveness.

179 Using QIP to Create a Structured Teaching Programme to Improve Confidence in Basic Surgical Topics in Foundation Year 1 Doctors

Aim

We aim to create a new, structured teaching programme to help fill in knowledge gaps in newly qualified doctors, who have rotated into General Surgery.

Method

We ran the programme over three four-month periods.

Prior to each rotation, we used a survey to assess multiple aspects: prior experience of surgical teaching, overall feeling of preparedness and confidence. We also asked for a self-evaluation on the doctor's confidence for specific basic surgical topics, on a 5-point scale. We asked for suggestion topics that doctors found difficult or lacked confidence in. We used this information to create a curriculum for the programme.

We then reassessed these variables at the end of the cycle, using the information to plan and implement the next cycle.

Results

During the first cycle, we made no significant difference in any area. Experiencing significant barriers to attendance, organisation, and interaction with the survey. We used this first cycle to identify these barriers and address them for the second cycle.

These changes led to a significant improvement in attendance, feedback from sessions and interaction with the questionnaires. We saw a 3-fold increase in attendance to sessions on average.

After the second cycle, there was an overall improvement of confidence in all basic surgical topics. There was an increase in the number of doctors considering a career in surgery.

Conclusions

This teaching programme has led to an improvement in junior doctors’ confidence in basic surgical topics. Repeated PDSA cycles are allowing continuous improvement and change to maximise exposure to surgical teaching and training.

Comparison of scattered entrance skin dose burden in MSCT, CBCT, and X-ray for suspected scaphoid injury: Regional dose measurements in a phantom model

INTRODUCTION

Scaphoid radiography has poor sensitivity for acute fracture detection and often requires repeat delayed imaging. Although magnetic resonance (MR) imaging is considered the gold standard, computed tomography (CT) is often used as an alternative due to ease of access. Cone-Beam CT (CBCT) offers equivalent diagnostic efficacy to Multi Slice CT (MSCT) at reduced dose. We aimed to establish the difference in scattered dose between modalities for scaphoid imaging.

METHODS

Anatomical regional entrance surface dose measurements were taken at 3 regions on an anthropomorphic torso phantom positioned as a patient to a wrist phantom undergoing scaphoid imaging for three modalities (CBCT, MSCT, four-view projection radiography). Exposure factors were based on audit of clinical exposures. Each dose measurement was repeated three times per anatomical region, modality, exposure setting and projection.

RESULTS

Under unpaired T-test CBCT gave significantly lower mean dose at the neck (1.64 vs 18 mGy), chest (2.78 vs 8.01) and abdomen (1.288 vs 2.93) than MSCT (p < .0001). However CBCT had significantly higher mean dose than four-view radiography at the neck, chest and abdomen (0.031, 0.035, and 0.021 mGy) (p < .0001).

CONCLUSION

CBCT of the wrist carries a significantly higher scattered radiation dose to the neck, chest and abdomen than four view scaphoid radiography, but significantly lower scattered dose than MSCT of the wrist of equivalent diagnostic value.

IMPLICATIONS FOR PRACTICE

The use of CBCT for scaphoid injury carries significantly lower scattered dose to radio-sensitive structures investigated here than equivalent MSCT, and may be of greater use as an early cross-sectional investigation for suspected scaphoid fracture.

A Women's Rights-Based Approach to Reducing Child Mortality: Data from 193 Countries Show that Gender Equality does Affect Under-five Child Mortality

OBJECTIVES

Mother's health and wellbeing significantly affects child health. Women's autonomy can improve healthcare-seeking behaviour, utilisation of healthcare services, and planned pregnancy, thereby improving child health. The global under-five mortality rate (U5MR) has seen the fastest decline in the past two decades, but the influence of gender equality on child mortality remains unaddressed. A strategic approach addressing gender equality is needed to reduce the U5MR further. The study aimed to identify and investigate the association between indicators of gender equality and U5MR using a human rights-based approach.

METHODS

We analysed open-source secondary data from international agencies comprising 521 gender-sensitive variables for 193 countries. Nine variables were included for the final Structural Equation Model based on the theoretical model. Model 1 consisted of 193 countries, and Model 2 comprised a subgroup analysis of 11 variables for 158 countries. Gender equality was a latent variable, and the U5MR was the outcome variable.

RESULTS

Gender equality was significantly associated with U5MR (Z = - 7.47, 95% CI = - 754.67 to - 440.98, p < 0‧001, n = 193 for Model 1, and Z = - 7.71, 95% CI = - 808.26 to - 480.72, p < 0‧001, n = 158 for Model 2). Female education, women's waged and salaried employment, women as employers, and women's representation in leadership and parliament enhanced gender equality, whereas the prevalence of child marriage and intimate partner violence (IPV) negatively affected gender equality. Improvement in gender equality significantly reduced U5MR. CONCLUSIONS FOR PRACTICE: Improving women's economic, educational, and social position and increasing female representation in higher leadership and policymaking positions is the key to reducing child mortality. Notably, eliminating child marriage and IPV is the key to achieving gender equality and is needed at the forefront of national policies. Gender equality can significantly improve women's reproductive autonomy, a critical factor in improving healthcare utilisation for women and their children.

Perceptions of Family Caregivers of People With Dementia Regarding Symptom Management and the COVID-19 Pandemic

Nearly 98% of older adults with Alzheimer’s disease and related dementias (ADRD) experience behavioral and psychological symptoms of dementia (BPSD). Although BPSD are linked to caregiver burden, perceptions of family caregivers on the impact of BPSD and their experiences addressing them in the home are unclear, and little is known about the impact of the pandemic on these experiences. Study aims were to explore: 1) the experiences of family caregivers of community dwelling older adults with ADRD regarding BPSD and how they manage BPSD in the home, and 2) how the pandemic impacted family caregivers’ experiences, BPSD of their relatives, and BPSD management. A qualitative, exploratory approach was used; 21 family caregivers were interviewed virtually. Content analysis and constant comparative methods were used. Ten major themes emerged: 1) Emotional and psychological responses of caregiver, 2) Loss, 3) Anticipation, 4) Reliance, 5) Learning to caregive, 6) Rewarding, 7) Emotional and psychological responses of care recipient 8) Cognition of care recipient, 9) Care strategies, 10) Caregiver perspectives. Caregivers did not use terms “behaviors” or “symptoms”, instead they described their relatives’ and their own experiences interdependently. Caregiving challenges presented before the pandemic (e.g. equivocal effects of medications, increasing care demands), many of which were compounded by the pandemic. Future research should explore the experiences of caregivers from a range of backgrounds. Findings illustrate communication barriers exist between clinicians, community services, people with ADRD and their families which may be addressed through clinician education, family-centered care planning, and policies to expand support service access.

Caregiving Intensity and Depressive Symptoms Among Older Adults After Partners’ Onset of Dementia

Caring for a partner with Alzheimer’s disease or related dementia (ADRD) can create tremendous care burdens. However, the extent to which onset of ADRD in a partner impacts caregiving intensity and emotional health, the relationship of increased care intensity to emotional health, and whether relationships vary across the older adult population, are less clear. We used 9 waves (years 2000-2016) of the nationally representative Health and Retirement Study dataset to examine the number of weekly caregiving hours provided and depressive symptoms for older (ages ≥51) individuals after partners' ADRD onset (measured with the Telephone Cognitive Interview Survey). We compared changes in outcomes from before to after partners' ADRD onset using zero-inflated negative binomial regression models, overall and among sub-populations with potential vulnerability to excess care burdens – women and racial/ethnic minorities. In our sample of 2,186 older Americans with 10,120 unique observations, we observed a 215% increase (p<0.001) in weekly caregiving hours provided and 21% increase (p<0.001) in depressive symptoms reported by older respondents after partners' ADRD onset. Even larger impacts were observed for women and for non-Hispanic whites. Increased amounts of caregiving were associated with increases in depressive symptoms after a partner's ADRD onset. In all, ADRD has substantial impacts on family. Improved support mechanisms, including enriched community resources, clinician focus on dyadic needs, respite care, and policy efforts such as tax credits for caregivers, will be needed to meet the needs of couples increasingly affected by ADRD.

Effects of testosterone administration on fMRI responses to executive function, aggressive behavior, and emotion processing tasks during severe exercise- and diet-induced energy deficit

BACKGROUND

Clinical administration of testosterone is widely used due to a variety of claimed physical and cognitive benefits. Testosterone administration is associated with enhanced brain and cognitive function, as well as mood, in energy-balanced males, although such relationships are controversial. However, the effects of testosterone administration on the brains of energy-deficient males, whose testosterone concentrations are likely to be well below normal, have not been investigated.

METHODS

This study collected functional magnetic resonance imaging (fMRI) data from 50 non-obese young men before (PRE) and shortly after (POST) 28 days of severe exercise-and-diet-induced energy deficit during which testosterone (200 mg testosterone enanthate per week in sesame oil, TEST) or placebo (sesame seed oil only, PLA) were administered. Scans were also collected after a post-energy-deficit weight regain period (REC). Participants completed five fMRI tasks that assessed aspects of: 1) executive function (Attention Network Task or ANT; Multi-Source Interference Task or MSIT; AXE Continuous Processing Task or AXCPT); 2) aggressive behavior (Provoked Aggression Task or AGG); and 3) latent emotion processing (Emotional Face Processing or EMO).

RESULTS

Changes over time in task-related fMRI activation in a priori defined task-critical brain regions during performance of 2 out of 5 tasks were significantly different between TEST and PLA, with TEST showing greater levels of activation during ANT in the right anterior cingulate gyrus at POST and during MSIT in several brain regions at REC. Changes over time in objective task performance were not statistically significant; testosterone-treated volunteers had greater self-reported anger during AGG at POST.

CONCLUSIONS

Testosterone administration can alter some aspects of brain function during severe energy deficit and increase levels of anger.

The College of Radiographers Research Strategy for the next five years

This article outlines the updated College of Radiographers (CoR) Research Strategy. This new research strategy will shape the approach to research from the radiography profession over the next five years. This will apply to all the profession and is aspirational and future thinking. The updated research strategy is the fifth research strategy presented by the CoR. Over the last five years, there have been considerable developments within healthcare and healthcare research. As this article is being written we are still in the middle of a global pandemic (Covid-19) which has influenced all our lives. However, despite the challenges of the last year, we are in a stronger position as a profession with more radiographers working towards and gaining masters and doctoral level qualifications. There are more radiographers working in clinical academic roles and there has been further development of radiographers coordinating and delivering research as well as becoming research leaders. This updated research strategy supports the radiography profession in delivering research-based practice over the next five years offering a framework within which radiographers can develop.

Development and preliminary testing of the collaboration for leadership and innovation in mentoring survey: An instrument of nursing PhD mentorship quality

BACKGROUND

High-quality PhD nursing student mentorship facilitates student and program success. Extant literature recommends evaluating and improving mentorship to foster optimal PhD student development. However, a comprehensive measure capturing all aspects of mentorship salient to PhD nursing student wellbeing and success is not available.

OBJECTIVES

The purpose of this pilot study was to develop a new instrument - the Collaboration for Leadership and Innovation in Mentoring (CLIM) - for quantifying important components of PhD student mentorship in nursing, and to preliminarily test its psychometric properties (content validity, sensitivity, test-retest reliability).

DESIGN

The study employed a cross-sectional design.

SETTING

The CLIM instrument was administered to nursing PhD students at a public state university in the United States.

PARTICIPANTS

Sixteen nursing PhD students at various stages in their degree progression completed the instrument.

METHODS

PhD nursing students developed unique items based on qualitative data collected by the University using an Appreciative Inquiry framework. Seven nursing and non-nursing experts with experience in PhD mentorship evaluated content validity. After revisions, the final 44-item instrument was administered at two time points (one month apart) to allow assessment of test-retest reliability. Test-retest reliability was evaluated using Spearman-rank correlations and data from students with ≥1 year of experience with their mentor.

RESULTS

Response rates were 94% for both administrations (n = 16). The instrument's overall Content Validity Index (CVI) was 0.91 (p = 0.05). Test-retest analyses resulted in high correlations (r = 0.91, p < 0.001), further supporting reliability of the CLIM instrument.

CONCLUSIONS

Preliminary evidence suggests that the CLIM instrument is a reliable instrument of PhD mentorship in nursing. However, additional testing in larger and more diverse graduate student populations is needed to evaluate internal consistency reliability, among other psychometric properties.

Evaluation of Intervention Acceptability in Community Studies With Individuals and Dyads Affected by Dementia

Multiple non-pharmacologic interventions for symptom management in community dwelling individuals with dementia have demonstrated effectiveness, but have had limited uptake in practice. Prior reviews have evaluated acceptability of interventions for caregivers, but none have evaluated interventions for care recipients with dementia and dyads. This review synthesized the evidence about intervention acceptability for dyads (individuals with dementia and informal caregivers) and individuals with dementia residing at home. Four databases were searched (PubMed, CINAHL, AgeLine, PsycINFO) using inclusion criteria of: intervention studies, community dwelling individuals with dementia or dyads of care recipients and informal caregivers, non-pharmacologic intervention, evaluation of intervention acceptability. Gray literature and non-English articles were excluded. 173 citations were screened by title and abstract, 38 were reviewed by full text, and 19 studies were included. 18 studies focused on dyads, and 13 different non-pharmacologic intervention types were evaluated across studies. Qualitative (n=3), quantitative (n=8) and mixed methods (n=8) were used to evaluate acceptability. Approaches and measures of acceptability included field notes, behavioral checklists, focus groups, semi-structured interviews, questionnaires, and completion rates of intervention sessions and outcome measures. Although participants’ benefit and satisfaction with the interventions were high across studies, variability in definitions of acceptability, the methods and measures used constrain the interpretation and generalizability of findings. Psychometric properties of quantitative questionnaires were not addressed even as the most basic level of face or content validity. To enhance the applicability of non-pharmacologic treatments for this population, future research should emphasize the evaluation of intervention acceptability, as well as effectiveness.
