The enigma of incisional hernia prediction unraveled: external validation of a prognostic model in colorectal cancer patients

PURPOSE

Accurate prediction of hernia occurrence is vital for surgical decision-making and patient management, particularly in colorectal surgery patients. While a hernia prediction model has been developed, its performance in external populations remain to be investigated. This study aims to validate the existing model on an external dataset of patients who underwent colorectal surgery.

METHODS

The "Penn Hernia Calculator" model was externally validated using the Hughes Abdominal Repair Trial (HART) data, a randomized trial comparing colorectal cancer surgery closure techniques. The data encompassed demographics, comorbidities, and surgical specifics. Patients without complete follow-up were omitted. Model performance was assessed using key metrics, including area under the curve (AUC-ROC and AUC-PR) and Brier score. Reporting followed the TRIPOD consensus.

RESULTS

An external international dataset consisting of 802 colorectal surgery patients were identified, of which 674 patients with up to 2 years follow-up were included. Average patient age was 68 years, with 63.8% male. The average BMI was 28.1. Prevalence of diabetes, hypertension, and smoking were 15.7%, 16.3%, and 36.5%, respectively. Additionally, 7.9% of patients had a previous hernia. The most common operation types were low anterior resection (35.3%) and right hemicolectomy (34.4%). Hernia were observed in 24% of cases by 2-year follow-up. The external validation model revealed an AUC-ROC of 0.66, AUC-PR of 0.72, and a Brier score of 0.2.

CONCLUSION

The hernia prediction model demonstrated moderate performance in the external validation. Its potential generalizability, specifically in those undergoing colorectal surgery, may suggest utility in identifying and managing high-risk hernia candidates.

Assisted reproductive techniques and subsequent risk of asthma and allergic rhinitis in offspring: a nationwide birth cohort study in South Korea

OBJECTIVE

The relationship between assisted reproductive techniques (ART) and the risk of asthma and allergic rhinitis (AR) is controversial. Thus, we aimed to investigate the relationship between ART and the risk of asthma and AR in a nationwide, large-scale birth cohort.

PATIENTS AND METHODS

This study utilized the National Health Insurance Service data in South Korea to conduct a nationwide, large-scale, population-based birth cohort. We included all infants born between 2017 and 2018. AR, asthma, food allergies, and atopic dermatitis were defined using the International Classification of Diseases tenth edition codes. Asthma was classified as allergic or non-allergic based on accompanying allergic diseases (AR, food allergy, or atopic dermatitis). Using 1:10 propensity score matching, we compared infants conceived through ART with those conceived naturally (non-ART). After matching, logistic regression was used to compare the hazard ratio for asthma and AR between the two groups.

RESULTS

We included 543,178 infants [male infants, 280,194 (51.38%)]. After matching, 8,925 and 74,229 infants were selected for the ART and non-ART groups, respectively. The ART group showed a decreased risk of asthma in the offspring [adjusted hazard ratio (aHR), 0.45; 95% confidence interval (CI), 0.41-0.48]. Similarly, for AR, being conceived by ART was associated with a decreased risk of AR (aHR, 0.25; 95% CI, 0.12-0.37). ART offspring showed a decreased risk of asthma and AR in offspring compared to that observed in non-ART offspring.

CONCLUSIONS

Our study offers important insights for clinicians, researchers, and parents regarding the health outcomes of ART-conceived infants and enhances our understanding of ART's impact on respiratory health.

Cystoscopic application of PuraStat® in the treatment of radiation-induced haemorrhagic cystitis

The use of radiotherapy has increased in recent years, especially for pelvic neoplasms, and this can result in long-term complications such as recurrent haemorrhagic radiation cystitis (RHC). A 73-year-old male patient presented to a hospital emergency department multiple times with visible haematuria and clots leading to urinary clot retention; he was finally diagnosed with RHC. During the last presentation, the bladder was irrigated continuously with saline using a three-way catheter. During hospitalisation, a cystourethroscopy was performed for bladder evaluation and clot evacuation. Multiple bleeding ulcers were recognised on the bladder wall, biopsies were taken for histopathology, and the ulcers cauterised. Packed red blood cell transfusions were required, and sodium hyaluronate (CystiStat®) bladder instillations were tried. There was no clinical improvement following any of these interventions. In light of the patient's deteriorating condition, cystoscopic application of PuraStat® 3ml was administered, which led to remission of the urinary bleeding in the short term. We continue to monitor the effects in the medium and long term. Based on current data, PuraStat® haemostatic agent therapy may be considered for RHC, when traditional treatments are ineffective or infeasible, potentially eliminating the need for more aggressive therapy such as cystectomy.

Achievement of Target Gain Larger than Unity in an Inertial Fusion Experiment

On December 5, 2022, an indirect drive fusion implosion on the National Ignition Facility (NIF) achieved a target gain G_{target} of 1.5. This is the first laboratory demonstration of exceeding "scientific breakeven" (or G_{target}>1) where 2.05 MJ of 351 nm laser light produced 3.1 MJ of total fusion yield, a result which significantly exceeds the Lawson criterion for fusion ignition as reported in a previous NIF implosion [H. Abu-Shawareb et al. (Indirect Drive ICF Collaboration), Phys. Rev. Lett. 129, 075001 (2022)PRLTAO0031-900710.1103/PhysRevLett.129.075001]. This achievement is the culmination of more than five decades of research and gives proof that laboratory fusion, based on fundamental physics principles, is possible. This Letter reports on the target, laser, design, and experimental advancements that led to this result.

National long-term trends in health-related quality of life using EQ-5D-3L in South Korea, 2008-2021, including the COVID-19 pandemic: a representative serial study of 2.8 million people

OBJECTIVE

There is a scarcity of literature investigating the impact of the coronavirus disease 2019 (COVID-19) pandemic on long-term trends in health-related quality of life (HrQoL) using large-scale and representative data. Thus, we aimed to investigate the nationwide and long-term trends in quality of life (QoL) using the European Quality of Life- 5 dimensions, 3-level version (EQ-5D-3L) from a Korean representative serial study of 2.8 million people, 2008-2021.

SUBJECTS AND METHODS

This Korean study used data on adults between 2008 and 2021 who participated in the Community Health Survey. Timeframes were categorized as COVID-19 mid-pandemic (2021) and pre-pandemic (2008-2019). The mean EQ-5D-3L index for the whole population and subgroups stratified by demographic characters was evaluated for each timeframe, and differences between before and during the COVID-19 pandemic were also analyzed.

RESULTS

2,827,240 adults who responded to the survey, 2008-2021, were eligible for this study. Overall EQ-5D index persistently decreased from 2008-2016, then minimally decreased during the pandemic, still being much higher than forecasted before the COVID-19 pandemic. The reduction in the rate of decline in QoL after the COVID-19 outbreak was especially marked in white-collared, young adults, people with 'good' or 'very good' subjective health, and college-educated or above group. On the other hand, the previously increasing trend of QoL in the elderly group has decelerated during the pandemic, and QoL of the 'very bad' subjective health group recorded the lowest in the whole study period.

CONCLUSIONS

The present study investigated the long-term trend of QoL in Korean adults using serial data over the past 14 years, with a special emphasis on comparing the pre- and mid-COVID-19 pandemic periods.

Wellness Warriors: a qualitative exploration of healthcare staff learning to support their colleagues in the aftermath of the Australian bushfires

PURPOSE

Healthcare staff are on the frontline during disasters despite any personal adversity and vicarious trauma they may be experiencing. Wellness Warrior training is a post-disaster intervention developed in response to the 2019-2020 Australian bushfires to support staff in a rural hospital located on the South Coast of New South Wales, Australia.

METHOD

This study explored the experiences and perspectives of 18 healthcare staff who were trained to provide emotional and peer support to their colleagues in the aftermath of a crisis. All the Wellness Warriors participated in semi-structured interviews between March and April 2020. Data were analysed using the reflexive thematic approach.

RESULTS

Healthcare staff reported developing interpersonal skills around deep listening and connecting with others which allowed for hearing the core of their colleagues' concerns. The training also helped staff to feel differently about work and restored their faith in healthcare leadership.

CONCLUSION

Wellness Warrior training provided staff with knowledge and skills to support their colleagues in the aftermath of a natural disaster and later during the COVID-19 pandemic. As such, these findings suggest that peer support programs such as Wellness Warriors could be one way healthcare organisations can attempt to alleviate the psychological impact of natural disasters.

National trends in the prevalence of hepatitis B and C in South Korea, before and during the COVID-19 pandemic (2007-2021) - a nationwide representative study

OBJECTIVE

Due to the various changes caused by the COVID-19 pandemic, some infectious diseases showed different epidemiology and prevalence during the pandemic. However, there is a lack of comprehensive studies on trends in the prevalence of hepatitis B and C related to the pandemic. Thus, we compared the prevalence of hepatitis B and C before and during the COVID-19 pandemic in South Korea.

SUBJECTS AND METHODS

We conducted a comprehensive trend analysis with a nationwide serial cross-sectional survey from 2007 to 2021 (n=86,931) using the Korea National Health and Nutrition Examination Survey (KNHANES). The changes in the prevalence of hepatitis B and C were evaluated using a weighted regression model to assess the impact of the COVID-19 pandemic.

RESULTS

From 2007 to 2021, 86,931 Korean adults aged 19 or older were included in the KNHANES data. The prevalence of hepatitis B showed a declining trend until the onset of the pandemic (1.80% in 2007-2009; 1.08% in 2016-2019; and 1.01% in 2020), at which point this trend reversed (1.39% in 2021). The prevalence of hepatitis C remained stable (0.14% in 2007-2009 and 0.18% in 2016-2019), with no particular surge related to the COVID-19 pandemic (βdiff, -0.002; 95% CI, -0.761 to 0.756). For hepatitis B, old age was identified as a pandemic-related vulnerable factor (ratio of odds ratio, 1.68; 95% CI, 1.05-2.70).

CONCLUSIONS

In this study, unlike other infectious diseases, hepatitis B and C did not show a decreasing trend during the pandemic. In particular, hepatitis B showed a rebound trend during the pandemic, which was noticeable in those aged 60 or older. Further studies are needed to support these findings.

Body mass index and nutritional intake following Elexacaftor/Tezacaftor/Ivacaftor modulator therapy in adults with cystic fibrosis

BACKGROUND

Elexacaftor/Tezacaftor/Ivacaftor (ETI) modulator therapy is often associated with increased body mass index (BMI) in people with cystic fibrosis (CF). This is thought to reflect improved clinical stability and increased appetite and nutritional intake. We explored the change in BMI and nutritional intake following ETI modulator therapy in adults with CF.

METHODS

Dietary intake, measured with myfood24®, and BMI were collected from adults with CF at baseline and follow-up as part of an observational study. Changes in BMI and nutritional intake in participants who commenced ETI therapy between time points were assessed. To contextualize findings, we also assessed changes in BMI and nutritional intake between study points in a group on no modulators.

RESULTS

In the pre and post ETI threapy group (n = 40), BMI significantly increased from 23.0 kg/m2 (IQR 21.4, 25.3) at baseline to 24.6 kg/m2 (IQR 23.0, 26.7) at follow-up (p<0.001), with a median of 68 weeks between time points (range 20-94 weeks) and median duration of ETI therapy was 23 weeks (range 7-72 weeks). There was a significant decrease in energy intake from 2551 kcal/day (IQR 2107, 3115) to 2153 kcal/day (IQR 1648, 2606), p<0.001. In the no modulator group (n = 10), BMI and energy intake did not significantly change between time points (p>0.05), a median of 28 weeks apart (range 20-76 weeks).

CONCLUSIONS

These findings tentatively suggest that the increase in BMI with ETI therapy may not simply be attributable to an increase in oral intake. Further exploration into the underlying aetiology of weight gain with ETI therapy is needed.

Physical activity levels in female breast cancer patients and survivors in Ekurhuleni, South Africa

Background

By using complementary therapies, such as exercise rehabilitation during and after cancer treatment, breast cancer patients and survivors can improve their quality of life and overall health while also negating the deleterious effects of breast cancer and its treatment.

Objectives

The aim of this study was to determine the physical activity levels of female breast cancer patients and survivors in Ekurhuleni, South Africa.

Methods

The International Global Physical Activity Questionnaire (2002) determined participants' physical activity levels during work, travel and leisure. The questionnaire was disseminated to medical facilities in hard copy format and online via the Google Forms platform. Statistics were computed using the Statistical Package for Social Science (SPSS) with the level of significance set at 95% (p < 0.05).

Results

One hundred female breast cancer patients and survivors with a mean age of 55 years from Ekurhuleni, South Africa participated in this study. The findings reflected that most participants (59%) were meeting the American College of Sports Medicine's physical activity guidelines when considering activity done during work, travel and leisure. No significant difference was seen in physical activity participation between breast cancer patients and breast cancer survivors, or those attending private and public facilities.

Conclusion

For the breast cancer patient, physical activity and exercise may be a promising and effective adjuvant treatment both during and after anticancer therapies, improving quality of life, playing a role in increasing treatment tolerance, mitigating a range of symptoms and side effects brought on by cancer diagnosis and treatments and enhancing outcomes.

Reflections of maternity service users and midwives' on the co-creation of interventions to support midwives addressing alcohol during antenatal care

BACKGROUND

There are divergent perspectives between midwives and pregnant women on how alcohol consumption during pregnancy could be addressed. Co-creation is an approach where lay people and professionals work together as equal partners, offering the opportunity to bridge the gap.

OBJECTIVES

Our aim was to evaluate how well we carried out authentic co-creation of an intervention to support midwives have a dialogue about alcohol consumption with pregnant women.

PATIENT INVOLVEMENT

Recent maternity service users including women with experience of harm due to alcohol during pregnancy provided feedback on the design, conduct and dissemination of the study.

METHODS

An iterative co-creation approach rooted in participatory research methods was used. Five online workshops were carried out with thirteen midwives and six maternity service users via Zoom July-August 2021. Data were analysed using the core values of co-create as a framework: equality, inclusivity, holistic, resource, positivity, transparency, iterative, and sustainability.

RESULTS

The co-creation process was productive and rewarding to midwives and maternity service users. There were positive experiences across the co-creation framework with some unintended positive consequences for maternity-service users.

DISCUSSION

This evaluation provides new knowledge on how well the co-creation process worked in relation to research involving a sensitive topic that can invite stigma. Co-creation projects require generous time and financial resources to ensure a high-quality process and robust outcome for all.

PRACTICAL VALUE

Co-creation of strategies involving both service providers and service users have potential to facilitate evidence-based practice.

FUNDING

This research is funded by the National Institute for Health Research (Reference: NIHR201128).

Increased Complication Rates with Proton Therapy in Breast Cancer Patients with Immediate, Implant-Based Reconstruction: Single-Institution Comparative Effectiveness Analysis

PURPOSE/OBJECTIVE(S)

To compare the impact of protons vs. photons on breast reconstruction complications, for patients (pts) receiving postmastectomy radiation (PMRT) with either single-stage direct-to-implant (DTI) or two-staged expander/implant (TE/I).

MATERIALS/METHODS

We reviewed the charts of 578 pts who underwent immediate reconstruction followed by radiation at our institution between 2010 and 2020. Pts with implant-based reconstruction using either TE/I or DTI and PMRT delivery in the presence of the prosthesis were included. Pts enrolled in active ongoing clinical trials were excluded from the analysis. The photon group received 3D conformal or IMRT/VMAT treatment with a median dose of 50-50.4 Gy in 25 to 28 fractions. For proton pts, treatment was delivered mainly with pencil beam scanning technique (PBS); few pts received passively scattered proton spread-out Bragg peak (SOBP). The complications were defined as infection/skin necrosis (I/N) requiring operative debridement, capsular contracture (CC) necessitating capsulotomy, and overall implant failure (ORF) as the removal of the permanent implant irrespective of replacement outcomes (i.e., with and without salvage reconstruction). We fit inverse-probability weighted cumulative incidence curves to adjust for confounding and non-random loss to follow-up. Various sensitivity analyses were conducted.

RESULTS

Four hundred ninety-five pts were available for the final analysis with an overall median follow-up of 55 months. 66 (13%) received protons, of which14 were treated with SOBP protons. 137 (28%) and 256 (56%) received photons with and without chest wall boost (CWB), respectively. The 5-year inverse probability-weighted risk of CC post-PMRT was 31% for protons vs. 10% for photons (RR:3.09, 95% CI: 1.77, 5.40). The 5 years ORF risk was 35.6% in protons compared to 22.7% in photons pts (RR: 1.57; 95% CI 1.0, 2.48). Hazard ratios from the adjusted Cox models were 3.79 (p<0.001) for CC and 2.05 (p<0.01) for ORF. No difference in I/N was noted between protons and photons pts. Sensitivity analysis showed that protons significantly increased CC risk vs photons both with CWB (HR:3.56, P<0.001) and without CWB (HR:3.9, p<0.001). Similar outcomes were observed with ORF, where protons increased the rate of ORF compared to photons, irrespective of CWB (HR 1.8, p = 0.038 with CWB; HR 2.4, p = 0.004 without CWB). No differences between PBS and SOBP proton techniques were noted.

CONCLUSION

Compared to photons, proton therapy increases the risk of capsular contracture requiring surgical intervention and hence overall reconstruction failure. This data should inform discussions about the risks and benefits of protons in patients with reconstruction, while awaiting mature data from ongoing clinical trials (RADCOMP) utilizing protons for breast cancer.

Medicolegal claims in general surgery: a 10-year retrospective review of claims against the NHS in England

INTRODUCTION

Every year 12,000 medicolegal claims are brought against the NHS in England at a cost of £8 billion-6.7% of the NHS England budget. In 1,000 of these claims the primary speciality is General Surgery. The aims of this paper were to examine 10 years of claims against General Surgery Departments in NHS England, identify the common causes and injuries, review the associated cost and suggest strategies for improvement.

METHODS

Data regarding medicolegal claims made against NHS General Surgical Departments in England from 2010 to 2020 were obtained from the Clinical Negligence Scheme for Trusts. A retrospective review was undertaken to examine the number of claims, cost of claims closed with and without damages, primary causes and primary injuries.

RESULTS

A total of 10,027 claims were made between 2010 and 2020. Of these, 9,377 were closed in that time, with cost totalling £851,558,930. Of claims closed, an average of 608 per year were closed with damages and 329 without damages. Claims with damages resulted in more than forty-five times greater cost per claim compared with those closed without damages. Overall, cost increased by over 50% between 2010 and 2020. Common causes included 'failure/delay in treatment', 'intraoperative problems' and 'failure/delay in diagnosis'. Common injuries included 'additional/unnecessary operation(s)', 'unnecessary pain', 'fatality' and 'bowel damage/dysfunction'.

CONCLUSION

Medicolegal expenditure represents a serious concern for the NHS, worsening each year. This retrospective review highlights the rising cost along with the most common causes and primary injuries. Action is required at every level of the NHS to improve surgical care, consent and communication with our patients, and by doing so minimise poor outcomes and their resultant medicolegal consequences.

A retrospective evaluation of supine pelvic radiography image quality using centring points and anatomical axial rotation, including reliability of measurements (ARLEX-P STUDY)

INTRODUCTION

Pelvic radiographs are commonly used for the investigation of a variety of conditions. Comparison between examinations requires a consistent radiographic technique but variations in image quality and radiographic centring points are frequently reported in the literature. The aim of this study was to establish the amount of variation in the radiographic centring point (RCP) and pelvic axial rotation (PAR), with a secondary aim of reporting the reliability of such measures.

METHODS

Using a previously acquired imaging archive, 633 adult pelvis/hip radiographs were identified on a Picture Archiving and Communication System (PACS). Radiographs with bilateral prostheses, evidence of acute pelvic trauma, projections acquired on a stretcher/trolley and those demonstrating large discontinuity between the detector and X-ray field centre were excluded. To determine centring point variation (+ values denote superior variations) and axial rotation multiple measurements were obtained from each radiograph. A video was used to train five observers and each of these reviewed ten random cases to determine inter- and intra-rater reliability. One of the five observers then performed the measurements on all remaining radiographs.

RESULTS

Following exclusions 380 radiographs were evaluated. The median (IQR) RCP deviation from the inter-acetabular line was +22 (+2 to +43) mm where both iliac crests were present and -29 (-45 to -12) mm where they were not. Eleven (3%) cases demonstrate RCP variation from the midline of greater than 25 mm (no bias towards the left or right side). The median (IQR) PAR was 0.0 (-1.5 to 1.4) degrees with greater variance in PAR for male participants (p = 0.004). Almost 60% of inter-rater ICC measurements were categorised as excellent, good or moderate.

CONCLUSION

Variations in RCP and PAR exist when evaluating a sample of routinely acquired pelvis radiographs. Some initial factors, such as sex and sub-examination type (full pelvis [XPEL] or low centred pelvis [XHIPB]) have been identified as having a statistical affect on variability. Further research and methods to standardise radiographic techniques is required and must be multidimensional in nature.

IMPLICATIONS FOR PRACTICE

Selection of radiographic technique, including RCP, appears to influence components of the pelvis radiograph. Given the increasing clinical requirements for pelvic radiography further standardisation alongside individual optimisation is warranted.

[Research updates on a role for retinal contrast in myopia control]

Animal research has established that signals derived from both contrast and defocus can influence refractive development, likely concurrently, so that overall refractive development reflects an integration of these primary visual signals. Important findings include the association of L/M opsin mutations with familial high myopia, axial hyperopia produced in response to form deprivation in moderate outdoor lighting levels, effective control of myopia by diffusion optics technology spectacle lenses designed to reduce retinal contrast, and all current defocus-based optical treatments which inadvertently reduce image contrast. In this review, clinical trial results of optical myopia treatment strategies that manipulate retinal contrast are considered in context of animal research outcomes. In conclusion, research suggests mild reductions in retinal contrast can slow myopia progression in children and may also have a role in defocus-based optical therapy.

Fuel reduction burning reduces wildfire severity during extreme fire events in south-eastern Australia

Extreme fire events have increased across south-eastern Australia owing to warmer and drier conditions driven by anthropogenic climate change. Fuel reduction burning is widely applied to reduce the occurrence and severity of wildfires; however, targeted assessment of the effectiveness of this practice is limited, especially under extreme climatic conditions. Our study utilises fire severity atlases for fuel reduction burns and wildfires to examine: (i) patterns in the extent of fuel treatment within planned burns (i.e., burn coverage) across different fire management zones, and; (ii) the effect of fuel reduction burning on the severity of wildfires under extreme climatic conditions. We assessed the effect of fuel reduction burning on wildfire severity across temporal and spatial scales (i.e., point and local landscape), while accounting for burn coverage and fire weather. Fuel reduction burn coverage was substantially lower (∼20-30%) than desired targets in fuel management zones focused on asset protection, but within the desired range in zones that focus on ecological objectives. At the point scale, wildfire severity was moderated in treated areas for at least 2-3 years after fuel treatment in shrubland and 3-5 years in forests, relative to areas that did not receive fuel reduction treatments (i.e., unburnt patches). Fuel availability strongly limited fire occurrence and severity within the first 18 months of fuel reduction burning, irrespective of fire weather. Fire weather was the dominant driver of high severity canopy defoliating fire by ∼3-5 years after fuel treatment. At the local landscape scale (i.e., 250 ha), the extent of high canopy scorch decreased marginally as the extent of recently (<5 years) treated fuels increased, though there was a high level of uncertainty around the effect of recent fuel treatment. Our findings demonstrate that during extreme fire events, very recent (i.e., <3 years) fuel reduction burning can aid wildfire suppression locally (i.e., near assets) but will have a highly variable effect on the extent and severity of wildfires at larger scales. The patchy coverage of fuel reduction burns in the wildland-urban interface indicates that considerable residual fuel hazard will often be present within the bounds of fuel reduction burns.

Identification of Vaccine Effects When Exposure Status Is Unknown

Results from randomized controlled trials (RCTs) help determine vaccination strategies and related public health policies. However, defining and identifying estimands that can guide policies in infectious disease settings is difficult, even in an RCT. The effects of vaccination critically depend on characteristics of the population of interest, such as the prevalence of infection, the number of vaccinated, and social behaviors. To mitigate the dependence on such characteristics, estimands, and study designs, that require conditioning or intervening on exposure to the infectious agent have been advocated. But a fundamental problem for both RCTs and observational studies is that exposure status is often unavailable or difficult to measure, which has made it impossible to apply existing methodology to study vaccine effects that account for exposure status. In this study, we present new results on this type of vaccine effects. Under plausible conditions, we show that point identification of certain relative effects is possible even when the exposure status is unknown. Furthermore, we derive sharp bounds on the corresponding absolute effects. We apply these results to estimate the effects of the ChAdOx1 nCoV-19 vaccine on SARS-CoV-2 disease (COVID-19) conditional on postvaccine exposure to the virus, using data from a large RCT.

Ictal face perception disturbance, tattoos, and reclaiming the self

We present a case of a young man with frightening ictal disturbance of face perception, or prosopometamorphopsia, arising from the left temporo-occipital region, leading to significant psychosocial impairment. A vivid forearm tattoo of the ictal experience conveyed its nature to the treating team and facilitated a psychotherapeutic process leading to significant psychosocial recovery. This case highlights the marked psychosocial and developmental impacts of epilepsy and the benefit of incorporating these into assessment and treatment.

Pain and physical activity levels among Rheumatoid Arthritis patients between the ages of 18 to 50 years in South Africa

Background

Little epidemiological research on rheumatoid arthritis (RA) has been done in Africa, suggesting that it is an uncommon illness. In rural South Africa, RA has an overall prevalence of 0.07% and a prevalence of 2.5% in urban areas; therefore, it is not as uncommon as perceived by the lack of research. Patient-centred programmes to improve physical function have been lacking and, as a result, the prior assumption was that physical activity should be avoided.

Objectives

To determine pain and physical activity levels among RA patients between the ages of 18 to 50 years in South Africa.

Methods

A combination of two questionnaires were used, namely, the Global Physical Activity Questionnaire (2002) and the Pain Outcomes Questionnaire (2003). The collated questionnaires were distributed by rheumatologists and on social media platforms to RA patients between the ages of 18 to 50 years old living in South Africa. This study had a sample size of 105 participants, with participation occurring through the online Google forms platform.

Results

One hundred and five participants with RA were recruited with an average age of 38±9 years. Most of the participants were females (93.3%). Seventy-two percent of the sample was classified as physically active, where work, leisure and travel activities were considered. No significant correlation between pain and physical activity was evident (r=0.10; p=0.311). Results showed significant correlations between pain and personal grooming (r=0.30; p=0.002), pain and ambulation (r=0.60; p=0.000), and pain and stair climbing (r=0.60; p=0.000).

Conclusion

Physical activity has proven to have multiple benefits for those suffering with RA. In this South African sample of RA patients, the majority were classified as physically active, and pain did not affect the activity levels of the involved participants. This study opens further research questions regarding RA prevalence in South Africa, and the type and intensity of physical activity that would be beneficial for RA.

Physical activity and quality of life of patients with fibromyalgia

Background

Fibromyalgia Syndrome (FMS) has been linked to decreased social functioning, poor mental health, and quality of life (QOL). Increased physical functioning and activity can result in improvements in social, mental and overall health, as well as lowered depression and anxiety levels.

Objectives

The aim of this study was to determine physical activity levels and QOL amongst patients diagnosed with fibromyalgia in the Johannesburg region of South Africa.

Methods

The research design was cross-sectional. Descriptive and quantitative data were collected. FMS patients (n=38) completed an online questionnaire on the Google Forms platform. The questionnaire was comprised of four components, namely Demographics, the Global Physical Activity Questionnaire (GPAQ), the Fibromyalgia Impact Questionnaire (FIQR), and the Short Form-36 (SF-36). During data analysis, descriptive characteristics and correlations were computed. The significance level was set at p ≤ 0.05.

Results

Results revealed high FIQR scores (67%) accompanied with low QOL scores (<50% in all domains). There was no correlation between physical activity and FIQR, and physical activity and QOL.

Conclusion

High scores on the impact of FMS were associated with lower overall QOL scores. However, the relationship between physical activity, and the impact of FMS and QOL remain inconclusive.

17-year trends of body mass index, overweight, and obesity among adolescents from 2005 to 2021, including the COVID-19 pandemic: a Korean national representative study

OBJECTIVE

There is a lack of pediatric studies that have analyzed trends in mean body mass index (BMI) and the prevalence of obesity and overweight over a period that includes the mid-stage of the COVID-19 pandemic. Thus, we aimed to investigate trends in BMI, overweight, and obesity among Korean adolescents from 2005 to 2021, including the COVID-19 pandemic.

SUBJECTS AND METHODS

We used data from the Korea Youth Risk Behavior Web-based Survey (KYRBS), which is nationally representative of South Korea. The study included middle- and high-school students between the ages of 12 and 18. We examined trends in mean BMI and prevalence of obesity and/or overweight during the COVID-19 pandemic and compared these to those of pre-pandemic trends in each subgroup by gender, grade, and residential region.

RESULTS

Data from 1,111,300 adolescents (mean age: 15.04 years) were analyzed. The estimated weighted mean BMI was 20.48 kg/m2 (95% CI, 20.46-20.51) between 2005 and 2007, and this was 21.61 kg/m2 (95% CI, 21.54-21.68) in 2021. The prevalence of overweight and obesity was 13.1% (95% CI, 12.9-13.3%) between 2005 and 2007 and 23.4% (95% CI, 22.8-24.0%) in 2021. The mean BMI and prevalence of obesity and overweight have gradually increased over the past 17 years; however, the extent of change in mean BMI and in the prevalence of obesity and overweight during the pandemic was distinctly less than before. The 17-year trends in the mean BMI, obesity, and overweight exhibited a considerable rise from 2005 to 2021; however, the slope during the COVID-19 pandemic (2020-2021) was significantly less prominent than in the pre-pandemic (2005-2019).

CONCLUSIONS

These findings enable us to comprehend long-term trends in the mean BMI of Korean adolescents and further emphasize the need for practical prevention measures against youth obesity and overweight.

Cerebral venous thrombosis after ChAdOx1 nCoV-19 vaccination: a systematic review

OBJECTIVE

To perform a systematic review of case reports or case series regarding thrombosis with thrombocytopenia syndrome (TTS) and cerebral venous thrombosis (CVT) related to ChAdOx1 nCoV-19 vaccination to address the clinical features, laboratory findings, treatment modalities, and prognosis related with CVT.

SUBJECTS AND METHODS

We included 64 TTS patients from 19 articles, 6 case series and 13 case reports, in which thrombosis occurred after the first dose of ChAdOx1 nCoV-19 vaccination published up to 30 June 2021 in Embase, ePubs, Medline/PubMed, Scopus, and Web of Science databases.

RESULTS

Of the 64 TTS patients, 38 (59.3%) had CVT. Patients with CVT were younger (median 36.5 vs. 52.5 years, p<0.001), had lower fibrinogen levels (130 vs. 245 mg/dL, p=0.008), had more frequent history of intracerebral hemorrhage (ICH), and had higher mortality rate (48.6% vs. 19.2%, p=0.020) than that of patients without CVT. In multivariable analysis, the possibility of presence of CVT was higher in younger age groups [odd ratio (OR): 0.91, 95% confidence interval (CI): (0.86-0.97, p<0.001)] and those with accompanying intracerebral hemorrhage (ICH) (OR: 13.60, 95% CI (1.28-144.12, p=0.045).

CONCLUSIONS

Our study demonstrated that CVT related to ChAdOx1 nCoV-19 vaccination was associated with younger age, low levels of fibrinogen, presence of ICH and more frequent mortality compared to those of non-CVT. If TTS occurs after ChAdOx1 nCoV-19 vaccination, the presence of CVT in patients with young age or ICH should be considered.

DEVELOPING A NOVEL FRAILTY INDEX TO STUDY FRAILTY OF SEXUAL AND GENDER MINORITY OLDER ADULTS IN THE ALL OF US DATABASE

Prevalence of frailty among older sexual and gender minority adults (OSGM) is unknown despite disparities in mental health, medical comorbidities, and physical function. The NIH-funded All of Us Program was launched May 2018 aiming to enroll 1 million US participants focusing on those underrepresented in biomedical research, including OSGM. Using validated methods, we developed an All of Us deficit accumulation frailty index (AoU-FI) consisting of 33-items using baseline survey responses of adults aged 50+. Deficit domains include comorbidities, physical functioning, mental health, cognition, and sensory impairment. AoU-FI was valid if ≤20% of items were missing and ≤70% were comorbidities. OSGM self-identified or had discordance between gender and sex responses. OSGM (n=5,678) and non-OSGM (n=66,325), were similar in age (mean (IQR) = 66.7 (60–73) vs 66.9 (60–74)) but were more diverse (White 78% vs 82%, Black 7.5% vs. 6.5%, Hispanic/Latino 6.9% vs. 5.9%). AoU-FI had an expected gamma distribution across groups. OSGM frailty had a narrower range (0–0.67 vs. 0–0.75) and higher mean of 0.19 (sd=0.11) vs 0.17 (sd=0.1) compared to non-OSGM. To our knowledge, this is the first study of frailty among OSGM. Findings suggest OSGM experience worse frailty, highlighting the need to understand disparities in frailty, identify interventions, and develop policies to support OSGM. Additionally, our novel AoU-FI creates opportunities to apply frailty to diverse participants and types of data from digital health to genomics within the All of Us database.

The global burden of sudden infant death syndrome from 1990 to 2019: a systematic analysis from the Global Burden of Disease study 2019

BACKGROUND

Sudden infant death syndrome (SIDS) still remains one of the leading causes of infant death worldwide, especially in high-income countries. To date, however, there is no detailed information on the global health burden of SIDS.

AIMS

To characterize the global disease burden of SIDS and its trends from 1990 to 2019 and to compare the burden of SIDS according to the socio-demographic index (SDI).

DESIGN

Systematic analysis based on the Global Burden of Disease (GBD) 2019 data.

METHODS

Epidemiological data of 204 countries from 1990 to 2019 were collected via various methods including civil registration and vital statistics in the original GBD study. Estimates for mortality and disease burden of SIDS were modeled. Crude mortality and mortality rates per 100 000 population were analyzed. Disability-adjusted life years (DALYs) and DALY rates were also assessed.

RESULTS

In 2019, mortality rate of SIDS accounted for 20.98 [95% Uncertainty Interval, 9.15-46.16] globally, which was a 51% decrease from 1990. SIDS was most prevalent in Western sub-Saharan Africa, High-income North America and Oceania in 2019. The burden of SIDS was higher in males than females consistently from 1990 to 2019. Higher SDI and income level was associated with lower burden of SIDS; furthermore, countries with higher SDI and income had greater decreases in SIDS burden from 1990 to 2019.

CONCLUSIONS

The burden of SIDS has decreased drastically from 1990 to 2019. However, the improvements have occurred disproportionately between regions and SDI levels. Focused preventive efforts in under-resourced populations are needed.

Socioeconomic differences in perinatal health outcomes: perinatal health surveillance through a health-equity prism

Background

Socioeconomic status (SES) is strongly associated with perinatal health outcomes, perpetuating intergenerational health inequalities. Our aim was to assess the utility of population data in Europe to monitor social inequalities in key perinatal health indicators.

Methods

Using the PHIRI federated analysis protocol to aggregate routine birth data from across Europe, we collected data on selected perinatal health indicators by SES from 2015 to 2020. Mothers’ education level (primary/lower secondary; upper secondary; postsecondary) was the preferred SES indicator; if unavailable, parents’ occupation or area-based deprivation scores were provided. The International Standard Classification of Occupations was used to group parents’ occupations into 4 categories, while area-based deprivation scores were measured in quintiles. For each country, we calculated risk ratios (RR) for preterm birth, stillbirth, neonatal death and caesarean delivery (CD) comparing the most with the least disadvantaged group

Results

17 countries provided data on maternal education, 5 on area-based deprivation, 1 on parents’ occupation and 2 could not provide data. For preterm birth, stillbirth and neonatal death, lower SES was associated with worse outcomes with most RR between lowest and highest groups in the range of 1.5 to 3.0. In contrast, in some countries, such as Croatia, Latvia, Lithuania and Spain, CD rates were higher for socially advantaged groups whereas the gradient was reversed in others (Denmark, Luxembourg, the Netherlands and Italy).

Conclusions

European countries can provide perinatal health indicators by SES, revealing marked socioeconomic inequalities in perinatal health. The differing SES gradient between countries for CD raise questions about care organization and clinical practice. Further exploration of the harmonization of differing SES measure across countries is required, while countries that do not monitor SES data should aim to improve existing systems.

Application of the patient navigation model with people experiencing homelessness: a scoping review

Background

Barriers in accessing healthcare services are a common issue that contributes to the disproportionately poor health outcomes in people who experience homelessness. A possible way to overcome these barriers and meaningfully engage with this under-served population is through the implementation of the so called patient navigation (PN) models. We conducted a systematic scoping review to gain a better understanding on how PN models are utilized with people experiencing homelessness and other comparable populations and to identify their features, barriers and facilitators to their implementation and their outcomes.

Methods

A systematic scoping review was done based on a predetermined protocol. We conducted a search of Web of Science, PubMed/Medline and Scopus databases on the 15th of June 2021. A narrative analysis of the included studies was conducted.

Results

Our search yielded 1203 hits, and after removing 475 duplicates, we were left with 728 publications of interest. Finally, 21 studies have been included in the review, comprising of nine review articles and 12 individual studies, with most studies stemming from the USA. Results show that PN models are consistently associated with improvements in a wide range of health related outcomes, mostly with timely access to healthcare services. Implementation strategies and measurements used in assessing PN models show heterogeneity between studies. However, a number of consistencies were found including; a longitudinal approach, using of non-clinical navigators who share similarities to the participant groups and who engage as facilitators. Additional considerations for gender and age may further improve the outcomes.

Conclusions

In order to improve on the success of the PN models and their application in removing barriers to healthcare access for people experiencing homelessness, more research is needed that focuses on the feasibility, acceptability and scalability of the approach outside the USA.

Key messages

• People experiencing homelessness experience considerable barriers in accessing healthcare service leading to disproportionately larger burden of disease as well as lower life expectancy.

• Patient navigation models have a great potential in removing barriers and facilitating timely access to healthcare services in people experiencing homelessness.

OC-050 “HAPPY TO CLOSE?”: THE RELATIONSHIP BETWEEN SURGICAL EXPERIENCE AND INCISIONAL HERNIA RATES FOLLOWING ABDOMINAL WALL CLOSURE IN COLORECTAL SURGERY

Introduction

Incisional Hernia (IH) is a common complication of colorectal surgery. Given high recurrence rates and associated morbidity, emphasis must be on prevention of IH. There is an association between surgeon volume and outcomes in hernia surgery, yet little evidence regarding impact of the experience of the surgeon performing abdominal wall closure (AWC) on IH rate.

Our aim was to assess the rates of IH at 1 year following surgery between Registrar and Consultant surgeons in patients undergoing elective colorectal surgery.

Methods

Patients undergoing elective surgery for colorectal cancer between 2014–2018 were identified through the Hughes Abdominal Repair Trial (HART), a prospective, multicentre randomised control trial. Grade of surgeon performing AWC was categorised into “Registrar” and “Consultant” and compared with IH detected at clinical examination at 1 year following surgery.

Results

663 patients were suitable for inclusion. 44% were closed by registrars (n=289). Groups were comparable in BMI, previous surgery and pre-operative IH. The rate of IH in patients closed by registrars was significantly higher than those closed by consultants (20% vs 12%, p&lt;0.01). Patients who underwent AWC by a registrar were 88% more likely to develop IH at 1 year (OR 1.88, 95%CI 1.23–2.86, p&lt;0.01).

Conclusion

Patients who undergo AWC by a registrar have an increased risk of developing IH compared to those closed by a consultant. Further work is needed to determine the impact of supervised and un-supervised trainees on IH rates, but AWC should be treated as training time rather than coffee time.

DD-01 THE INVITE STUDY: INCISIONAL HERNIA PREVENTION: RISK-BENEFIT FROM A PATIENT'S PERSPECTIVE

Introduction

Incisional Hernia (IH) is a common complication of abdominal surgery. IH is associated with significant morbidity to patients, and costs to the NHS. With no singular intervention demonstrated to bring the rate of IH below 12%, focus is now on pre-operative risk-prediction. High-risk patients may benefit from prophylactic mesh placement during their index operation, however with controversy surrounding the use of mesh, there is no understanding of whether this intervention is acceptable to patients.

Methods

This is a retrospective, single centre mixed-methods cohort study. Patients with and without IH who have undergone colorectal surgery will be approached, along with a smaller cohort of patients about to undergo surgery. Participants will be asked to complete a questionnaire and a sub-set of participants will be invited to semi-structured interviews. The primary objective is to assess the acceptability of prophylactic mesh to patients. Secondary outcomes include understanding patient's views on risk-predictive modelling, and factors that may influence or alter the acceptability of mesh.

Analysis

Questionnaires have been developed using a 5-point Likert scale to allow quantitative analysis. Qualitative analysis of interviews will be conducted using Clarke and Braun's framework of thematic analysis. Data will be presented using the Journal Article Reporting Standards (JARS) for mixed-methods research.

Outcomes

Ethical approval has been granted, and the trial is currently in set-up. Results from this study will be used to inform both in the design and recruitement of patients to future interventional trials using prophylactic mesh in the UK.

Incisional hernia following colorectal cancer surgery according to suture technique: Hughes Abdominal Repair Randomized Trial (HART)

BACKGROUND

Incisional hernias cause morbidity and may require further surgery. HART (Hughes Abdominal Repair Trial) assessed the effect of an alternative suture method on the incidence of incisional hernia following colorectal cancer surgery.

METHODS

A pragmatic multicentre single-blind RCT allocated patients undergoing midline incision for colorectal cancer to either Hughes closure (double far-near-near-far sutures of 1 nylon suture at 2-cm intervals along the fascia combined with conventional mass closure) or the surgeon's standard closure. The primary outcome was the incidence of incisional hernia at 1 year assessed by clinical examination. An intention-to-treat analysis was performed.

RESULTS

Between August 2014 and February 2018, 802 patients were randomized to either Hughes closure (401) or the standard mass closure group (401). At 1 year after surgery, 672 patients (83.7 per cent) were included in the primary outcome analysis; 50 of 339 patients (14.8 per cent) in the Hughes group and 57 of 333 (17.1 per cent) in the standard closure group had incisional hernia (OR 0.84, 95 per cent c.i. 0.55 to 1.27; P = 0.402). At 2 years, 78 patients (28.7 per cent) in the Hughes repair group and 84 (31.8 per cent) in the standard closure group had incisional hernia (OR 0.86, 0.59 to 1.25; P = 0.429). Adverse events were similar in the two groups, apart from the rate of surgical-site infection, which was higher in the Hughes group (13.2 versus 7.7 per cent; OR 1.82, 1.14 to 2.91; P = 0.011).

CONCLUSION

The incidence of incisional hernia after colorectal cancer surgery is high. There was no statistical difference in incidence between Hughes closure and mass closure at 1 or 2 years.

Perspectives and practices associated with consumer-directed care in Australia: Synergies and tensions in supporting planning and delivery of home care for older people with dementia

This study used a qualitative, cross-sectional design to address a gap in understanding the perspectives and practices of care planners and case managers in supporting consumer- directed care (CDC) for community dwelling people living with dementia. Semi-structured telephone interviews were conducted with a convenience sample of n = 16 planners and managers from seven providers of the Australian home care packages (HCP) program in NSW (Australia). All interviewees described the aspirations of supporting choice within CDC as synergistic with their values and with person-centred care. Some described new flexibilities within the more open-ended planning conversations enabled by CDC. However, most acknowledged their capacity to enable choice for clients with dementia was limited by the capped care budgets, as well as the skills and time needed to support choice and decision- making. Organisational practice changes associated with the shift to a market-based system were also perceived as limiting the capacity to support choices. Reducing centralised systems, increasing individual budgets and improving staff capacity to support decision-making by people with dementia may help to improve this situation. However, results suggest a deeper need to re-evaluate whether the CDC model is the most appropriate for supporting the rising numbers of people with dementia to age well in place.

Using a Delphi method to estimate the relevance of indicators for the assessment of shelter dog welfare

The European regulatory framework lacks standardisation as regards the minimum requirements for shelter facilities, making defining welfare standards for dogs challenging. Dog (Canis familiaris) welfare assessments should consist of a comprehensive set of measurements that allow the calculation of an overall 'welfare score.' The Shelter Quality protocol was developed for the purpose of assessing shelter dog welfare. The study aims to establish a standardised system for evaluating shelter dog welfare by obtaining agreement from experts on the weighting of different measures contributing to an overall welfare score. The Delphi technique is a widely used method for establishing consensus among experts. Two Delphi procedures were implemented and we compared their effectiveness in achieving expert consensus by evaluating rounds' numbers required to reach consensus and the response and attrition rates. Expert consensus was achieved in Delphi 1 when the standard deviation in the expert weightings was ≤ 5. This was achieved easily for the welfare score weightings of the four principles: 'Good feeding', 'Good housing', 'Good Health', and 'Appropriate behaviour.' Animal-based measures were found to reach consensus more quickly than resource-based measures. In Delphi 2, we used the coefficient of variation to determine consensus. No statistical differences were found between the two Delphi methods for attrition rate, response rate or number of participants. Continuing rounds until a consensus is reached is recommended as this method balances time and participant fatigue. A standardised scoring system is provided, using a single overall score of welfare that can be used to compare welfare standards between shelters.

Lawson Criterion for Ignition Exceeded in an Inertial Fusion Experiment

For more than half a century, researchers around the world have been engaged in attempts to achieve fusion ignition as a proof of principle of various fusion concepts. Following the Lawson criterion, an ignited plasma is one where the fusion heating power is high enough to overcome all the physical processes that cool the fusion plasma, creating a positive thermodynamic feedback loop with rapidly increasing temperature. In inertially confined fusion, ignition is a state where the fusion plasma can begin "burn propagation" into surrounding cold fuel, enabling the possibility of high energy gain. While "scientific breakeven" (i.e., unity target gain) has not yet been achieved (here target gain is 0.72, 1.37 MJ of fusion for 1.92 MJ of laser energy), this Letter reports the first controlled fusion experiment, using laser indirect drive, on the National Ignition Facility to produce capsule gain (here 5.8) and reach ignition by nine different formulations of the Lawson criterion.

Clinical characteristics with inflammation profiling of long COVID and association with 1-year recovery following hospitalisation in the UK: a prospective observational study

BACKGROUND

No effective pharmacological or non-pharmacological interventions exist for patients with long COVID. We aimed to describe recovery 1 year after hospital discharge for COVID-19, identify factors associated with patient-perceived recovery, and identify potential therapeutic targets by describing the underlying inflammatory profiles of the previously described recovery clusters at 5 months after hospital discharge.

METHODS

The Post-hospitalisation COVID-19 study (PHOSP-COVID) is a prospective, longitudinal cohort study recruiting adults (aged ≥18 years) discharged from hospital with COVID-19 across the UK. Recovery was assessed using patient-reported outcome measures, physical performance, and organ function at 5 months and 1 year after hospital discharge, and stratified by both patient-perceived recovery and recovery cluster. Hierarchical logistic regression modelling was performed for patient-perceived recovery at 1 year. Cluster analysis was done using the clustering large applications k-medoids approach using clinical outcomes at 5 months. Inflammatory protein profiling was analysed from plasma at the 5-month visit. This study is registered on the ISRCTN Registry, ISRCTN10980107, and recruitment is ongoing.

FINDINGS

2320 participants discharged from hospital between March 7, 2020, and April 18, 2021, were assessed at 5 months after discharge and 807 (32·7%) participants completed both the 5-month and 1-year visits. 279 (35·6%) of these 807 patients were women and 505 (64·4%) were men, with a mean age of 58·7 (SD 12·5) years, and 224 (27·8%) had received invasive mechanical ventilation (WHO class 7-9). The proportion of patients reporting full recovery was unchanged between 5 months (501 [25·5%] of 1965) and 1 year (232 [28·9%] of 804). Factors associated with being less likely to report full recovery at 1 year were female sex (odds ratio 0·68 [95% CI 0·46-0·99]), obesity (0·50 [0·34-0·74]) and invasive mechanical ventilation (0·42 [0·23-0·76]). Cluster analysis (n=1636) corroborated the previously reported four clusters: very severe, severe, moderate with cognitive impairment, and mild, relating to the severity of physical health, mental health, and cognitive impairment at 5 months. We found increased inflammatory mediators of tissue damage and repair in both the very severe and the moderate with cognitive impairment clusters compared with the mild cluster, including IL-6 concentration, which was increased in both comparisons (n=626 participants). We found a substantial deficit in median EQ-5D-5L utility index from before COVID-19 (retrospective assessment; 0·88 [IQR 0·74-1·00]), at 5 months (0·74 [0·64-0·88]) to 1 year (0·75 [0·62-0·88]), with minimal improvements across all outcome measures at 1 year after discharge in the whole cohort and within each of the four clusters.

INTERPRETATION

The sequelae of a hospital admission with COVID-19 were substantial 1 year after discharge across a range of health domains, with the minority in our cohort feeling fully recovered. Patient-perceived health-related quality of life was reduced at 1 year compared with before hospital admission. Systematic inflammation and obesity are potential treatable traits that warrant further investigation in clinical trials.

Using Journey Mapping to support staff, family members and allies of people with dementia to think and act differently during a care transition: The benefits and limits of care imagination

Research methods are not just for data collection, but can also be engaged in to promote more immediate benefits for participants and to create social change. This paper reports on how journey mapping was used with staff and family members of people with dementia in a residential aged care facility in regional NSW, Australia. The study was conducted in the context of a care transition, where residents, including people with dementia moved from an existing site to another new facility. Care transitions are frequent yet difficult for people with dementia to negotiate, so it was important to predict their nature and understand what might make the move easier. We used an innovative visual method known as ‘journey mapping’ to engage 45 staff and 18 family members to inform supports for 30 people with dementia, who had been identified as needing additional support during the planned transition. The journey mapping process was useful for fostering the caring imagination and encouraging active and creative planning around change for the people with dementia. It also highlighted the entrenched inequalities in the aged care sector, where poorly paid staff wanted to enact broad ranging supports but felt unsupported to do so. In other words, to improving and re-imagining transitional care for people with dementia requires structural and systemic change rather than just localised re-imaginings. [245]

CHALLENGE and Face Your Fears: Virtual Reality Treatment for Auditory Hallucinations and Paranoid Ideations

Background: Many patients suffering from schizophrenia spectrum disorders continue having distressing auditory hallucinations and paranoid ideations despite receiving current treatment. Virtual reality assisted treatment offers the potential of advancing current psychotherapies for psychotic symptoms by creating virtual environments that can elicit responses (e.g. thoughts, feelings, behaviours) mirroring real-world settings. In two large-scale randomised clinical trials, we are investigating whether targeted virtual reality assisted psychotherapy can reduce psychotic symptoms and increase daily life functioning and quality of life. The CHALLENGE trial examines whether nine sessions of virtual reality-assisted psychotherapy is superior to nine sessions of standard treatments in reducing the severity, frequency, and distress of auditory hallucinations in patients with psychosis. In the Face your Fears trial we are investigating whether virtual reality assisted cognitive behavioral therapy (CBT) is superior to standard CBT in reducing levels of paranoid ideation in patients with psychosis spectrum disorders. Methods: The CHALLENGE and Face your Fears trials are randomised, assessor-blinded parallel-groups superiority clinical trials, allocating a total of 266 and 256 patients, respectively to either the experimental intervention or a control condition. The trials are currently enrolling patients; thus, no quantitative data is available yet. The main objective of this presentation is to give a qualitative account of this new psychotherapeutic methods as it is applied in both trials. Results: Qualitative data comprising case descriptions and video material will be presented at the conference. Discussion: The preliminary findings indicate great potential for these innovative treatments albeit important concerns regarding implementation will be raised.

Bipolar Stigma in Jewish Communities in the United States

Introduction

This study investigated differences in mood disorder public stigma endorsed by Jewish adults. Specifically, it examined the association between public stigma and the symptomatology and gender of individuals with mood disorders and characteristics of respondents. The symptomatology investigated included major depressive disorder and bipolar disorder presenting with mania or depression. The public stigma factors measured for mood disorders were recovery, relationship disruption, hygiene, anxiety, and treatment/professional efficacy.

Objectives

Do symptomatology and gender predict stigma for mood disorders? For Jewish adults, do gender, age, religious characteristics, mental health history, and perceived stigma for mental illness predict their stigma toward individuals with mood disorders?

Methods

A convenience sample of 243 Jewish adults were randomly administered vignettes using a factorial design. MANCOVA was used for analysis. The Mental Illness Stigma Scale (Day et al., 2007) and the Devaluation of Consumer scale (Struening et al., 2001) were used to measure public and perceived stigma respectively.

Results

showed that recovery, relationship disruption, and hygiene stigmas were associated with vignette subject symptomatology, an interaction was found between respondent gender and age for treatability/professional efficacy stigma, and perceived stigma was correlated with public stigma factors. Consistent with previous research, the highest levels of stigma were found for individuals with bipolar disorder presenting with mania (Wolkenstein & Meyer, 2008).

Conclusions

These findings increase our knowledge of mood disorder stigma existing in the Jewish community and supports research showing that bipolar disorder presenting with mania is the most stigmatized type of mood disorder symptomatology (Wolkenstein & Meyer, 2008).

POS0686 EFFECTIVENESS OF UPADACITINIB IN THE TREATMENT OF RHEUMATOID ARTHRITIS: ANALYSIS OF 6-MONTH REAL-WORLD DATA FROM THE UNITED RHEUMATOLOGY NORMALIZED INTEGRATED COMMUNITY EVIDENCE (UR-NICETM) DATABASE

Background

The efficacy of upadacitinib (UPA), an oral Janus kinase inhibitor (JAKi), in the treatment of rheumatoid arthritis (RA) has been demonstrated in the phase 3 SELECT clinical trial program.1–6 However, few real-world data have been reported to date.

Objectives

To assess the 6-month effectiveness of UPA in patients (pts) with RA initiating UPA treatment in clinical practice.

Methods

This observational study included US-based pts from the United Rheumatology Normalized Integrated Community Evidence (UR-NICE) database who initiated UPA 15 mg once daily from Aug 2019 to the data cut-off in Nov 2021. Pts with ≥6 months of baseline (BL) data before UPA initiation, and with Clinical Disease Activity Index (CDAI) score recorded at BL and 6 months (±45 days) after initiation, were included in the analysis. Effectiveness measures included CDAI score, Routine Assessment of Patient Index Data 3 (RAPID3), and Disease Activity Score in 28 joints based on C-reactive protein (DAS28-CRP); patient-reported outcomes (PROs) including Health Assessment Questionnaire-Disability Index (HAQ-DI), Pain, and Patient’s Global Assessment of Disease Activity (PtGA); and Physician’s Global Assessment of Disease Activity (PhGA). Subgroup analyses were conducted by prior tumor necrosis factor inhibitor (TNFi) and tofacitinib (TOFA) treatment history.

Results

363 pts were included in the analysis and most were female (80.2%) (Table 1). 140 (39%) received UPA monotherapy and 223 (61%) received UPA plus conventional synthetic (cs) disease-modifying antirheumatic drugs (DMARDs). 83% of pts received prior csDMARDs, 72% prior biologics (TNFi 55%), and 41% JAKis (TOFA 39%). Overall, 46% (166/363), 23% (57/245), and 55% (95/173) of pts achieved LDA by CDAI, RAPID3, and DAS28-CRP, respectively, and 14% (51/363), 16% (39/245), and 36% (62/173) of pts achieved remission (REM) by CDAI, RAPID3, and DAS28-CRP, respectively. Results were similar regardless of prior TNFi or TOFA exposure (Figure 1). Improvements from BL were seen in PhGA and all PROs in the total population and all subgroups.

Conclusion

In this study, almost half (46%) of pts treated with UPA achieved CDAI LDA at 6 months and 14% achieved CDAI REM. Improvements in all PROs and PhGA were observed. Effectiveness of UPA was not impacted by prior TNFi or TOFA exposure, supporting UPA as an effective treatment option in clinical practice, including in pts with prior exposure to advanced therapy.

COVID-19 susceptibility and clinical outcomes in autoimmune inflammatory rheumatic diseases (AIRDs): a systematic review and meta-analysis

OBJECTIVE

This meta-analysis aims to assess the susceptibility to and clinical outcomes of COVID-19 in autoimmune inflammatory rheumatic disease (AIRD) and following AIRD drug use.

MATERIALS AND METHODS

We included observational and case-controlled studies assessing susceptibility and clinical outcomes of COVID-19 in patients with AIRD as well as the clinical outcomes of COVID-19 with or without use of steroids and conventional synthetic disease-modifying antirheumatic drugs (csDMARDs).

RESULTS

Meta-analysis including three studies showed that patients with AIRD are not more susceptible to COVID-19 compared to patients without AIRD or the general population (OR: 1.11, 95% CI: 0.58 to 2.14). Incidence of severe outcomes of COVID-19 (OR: 1.34, 95% CI: 0.76 to 2.35) and COVID-19 related death (OR: 1.21, 95% CI: 0.68 to 2.16) also did not show significant difference. The clinical outcomes of COVID-19 among AIRD patients with and without csDMARD or steroid showed that both use of steroid (OR: 1.69, 95% CI: 0.96 to 2.98) or csDMARD (OR: 1.35, 95% CI: 0.63 to 3.08) had no effect on clinical outcomes of COVID-19.

CONCLUSIONS

AIRD does not increase susceptibility to COVID-19, not affecting the clinical outcome of COVID-19. Similarly, the use of steroids or csDMARDs for AIRD does not worsen the clinical outcome.

The development and validation of the secondary exercise addiction scale

OBJECTIVES

Exercise addiction can be secondary to eating disorders, or a primary condition in the absence of another disorder. Currently, to determine secondary exercise addiction, two screening tools must be administered. The aim of this study was to validate a novel screening tool able to stratify between primary and secondary exercise addiction, called the secondary exercise addiction scale (SEAS).

METHODS

Phase 1 (n = 339) described the statistical reduction of an initial pool of scale items. Phase 2 (n = 382) used a confirmatory factor analysis (CFA) to examine the robustness of the latent structure. Phase 3 (n = 721) determined cut off scores for the eating disorder and exercise addiction sections of the SEAS and determine concurrent reliability with the exercise addiction inventory (EAI) and the SCOFF questionnaires. Phase 4 (n = 45) determined test-retest reliability.

RESULTS

Phase 1 extracted two components: exercise addiction and eating disorder symptomology, with 11 items retained. The CFA in Phase 2 showed an acceptable fit to the proposed model (comparative fit index = 0.93, Tucker Lewis Index = 0.91). Phase 3 determined cut off scores of  ≥ 28 (specificity = 91.97%), and  ≥ 20 (specificity = 96.27%) in the respective exercise addiction and eating disorders sections of the SEAS. The respective sections also correlated well with the EAI (r = 0.70, p =  < 0.001) and the SCOFF (r = 0.72, p =  < 0.001). Phase 4 showed excellent test-retest reliability (exercise addiction r = 0.95, p =  < 0.001, eating disorders r = 0.93, p =  < 0.001).

CONCLUSION

The SEAS appears to be a valid and reliable tool for measuring primary and secondary exercise addiction. Further studies are warranted to further validate this tool amongst clinical populations.

Issues and gaps in international guidance and national regulatory systems affecting international live insect trade

International trade in live insects involves the shipping of many different species, for various purposes, with a variety of handling requirements regulated by numerous authorities with varying objectives. The diversity of factors at play has both created and been subject to a complex regulatory landscape. A review of global production, shipping and use experiences from a range of perspectives has shown gaps and inconsistencies in international guidance and national implementation. Private carriers add another layer of uncertainty that is disproportionate to risks, resulting in variable practices and charges. Many benefits can come from international trade in insects, including pollinator services, control of pests and of disease vectors, and enhanced international scientific research and innovation. These benefits will be better achieved through a more evidence-based and efficient approach to regulating trade. This change in approach will in turn require an improved and widely accepted risk-management landscape for insect trade.

Clinical characteristics and treatments of multi-system inflammatory syndrome in children: a systematic review

OBJECTIVE

Multisystem inflammatory syndrome in children (MIS-C) can occur in association with coronavirus disease 2019 (COVID-19). It is not easy to differentiate MIS-C from severe COVID-19 or Kawasaki disease based on symptoms. The aim of this study was to describe the clinical and laboratory characteristics of MIS-C.

PATIENTS AND METHODS

We searched PubMed/Medline for case series and reports of MIS-C published until June 20, 2020. From a total of nine articles involving 45 cases, various clinical and laboratory data were extracted. Each target case was evaluated by using different diagnostic criteria.

RESULTS

The average age at onset of MIS-C was 8.6 years. In 80% of cases, the age of patients ranged from 5 to 15 years. Fever (100%) and shock (82%) were the most common presenting symptoms. Sixty percent of cases met the diagnostic criteria for typical or atypical Kawasaki disease. Biomarkers indicative of inflammation, coagulopathy, or cardiac injury were characteristically elevated as follows: ferritin (mean: 1,061 ng/mL), CRP (217 mg/L), ESR (69 mm/hr), IL-6 (214.8 pg/mL), TNFα (63.4 pg/mL), D-dimer (3,220 ng/mL), PT (15.5 s), troponin I (1,006 ng/L), and BNP (12,150 pg/mL). Intravenous immunoglobulin was administered in all target cases, and inotropic agents were commonly used as well. No case of death was observed.

CONCLUSIONS

This study demonstrated that MIS-C is a serious condition that presents with fever, rash, as well as cardiovascular and gastrointestinal symptoms. Although it is challenging to differentiate MIS-C from Kawasaki disease or severe COVID-19, initiation of appropriate treatments through early diagnosis is warranted.

Supporting the involvement of older adults with complex needs in evaluation of outcomes in long-term care at home programmes

Background

It is important to involve older people in evaluating public programmes that affect their lives. This includes those with physical and cognitive impairments (such as dementia) who may need support to live at home. Many countries have implemented new approaches to support older people to live well at home for longer. However, it can be challenging to involve disabled people in service evaluation, so we are unclear whether services are meeting their needs.

Aim

This study explored how a cascading methodology, offering different supports enabled the involvement of home care users with cognitive and physical impairments in the assessment of their care‐related quality of life.

Method

We used multiple tools from the Adult Social Care Outcomes Toolkit (ASCOT) with n = 63 older adults who were recipients of home care in the Illawarra. We also offered different physical and cognitive supports as needed.

Results

We started with the standard ASCOT questionnaire to assess the care‐related quality of life, but then offered alternative formats (including Easy Read) and supports (including physical and cognitive assistance) if the older person needed them to participate. This allowed us to involve a greater diversity of older people in the evaluation, and changed what we found out about whether their care needs were being met.

Conclusion

There is a need to implement more flexible and inclusive methods to increase the involvement of vulnerable users of long‐term care in the assessment of service outcomes. This is important to ensure that the perspectives of all service users inform the delivery of person‐centred care. It is also critical to understand the extent to which programmes are meeting the needs of vulnerable service users.

Patient or Public Contribution

Service users with dementia were involved in the design of the ‘Easy Read’ questionnaire used in the study.

An app with brief behavioural support to promote physical activity after a cancer diagnosis (APPROACH): study protocol for a pilot randomised controlled trial

Background

There are multiple health benefits from participating in physical activity after a cancer diagnosis, but many people living with and beyond cancer (LWBC) are not meeting physical activity guidelines. App-based interventions offer a promising platform for intervention delivery. This trial aims to pilot a theory-driven, app-based intervention that promotes brisk walking among people living with and beyond cancer. The primary aim is to investigate the feasibility and acceptability of study procedures before conducting a larger randomised controlled trial (RCT).

Methods

This is an individually randomised, two-armed pilot RCT. Patients with localised or metastatic breast, prostate, or colorectal cancer, who are aged 16 years or over, will be recruited from a single hospital site in South Yorkshire in the UK. The intervention includes an app designed to encourage brisk walking (Active 10) supplemented with habit-based behavioural support in the form of two brief telephone/video calls, an information leaflet, and walking planners. The primary outcomes will be feasibility and acceptability of the study procedures. Demographic and medical characteristics will be collected at baseline, through self-report and hospital records. Secondary outcomes for the pilot (assessed at 0 and 3 months) will be accelerometer measured and self-reported physical activity, body mass index (BMI) and waist circumference, and patient-reported outcomes of quality of life, fatigue, sleep, anxiety, depression, self-efficacy, and habit strength for walking. Qualitative interviews will explore experiences of participating or reasons for declining to participate. Parameters for the intended primary outcome measure (accelerometer measured average daily minutes of brisk walking (≥ 100 steps/min)) will inform a sample size calculation for the future RCT and a preliminary economic evaluation will be conducted.

Discussion

This pilot study will inform the design of a larger RCT to investigate the efficacy and cost-effectiveness of this intervention in people LWBC.
