Factors Affecting Mothers' Adherence to Home Exercise Programs Designed for Their Children with Cerebral Palsy

Cerebral palsy is a common motor disorder that results in long-term impairment. The purpose of this study was to find out what factors influence Saudi mothers' compliance with their Children with Cerebral Palsy (C-CP) Home Exercise Program (HEP). A self-administered online questionnaire was used to perform this qualitative research study on a group of 113 mothers who had children with CP. The study included mothers with children from birth to 12 years old who had received a HEP prescription from a physiotherapist. The measuring instrument tool was a questionnaire with two sections: demographic characteristics and a questionnaire about the parents' adherence to the HEP. The questionnaire utilized in this study was subjected to a reliability analysis, and the derived Cronbach's alpha was found to be 0.814 for the questionnaire (which had 17 phrases). These results imply that the questionnaire is reliable. A total of 113 responses were received, with 4 incomplete responses being eliminated. The majority of mothers (66.1%) did not follow the HEP, according to the findings of this survey. The demographics of the mothers revealed that 20-25-year-old mothers were more adherent than the other age groups. The findings of this study demonstrated that the physical therapist's treatment of the mother influenced exercise compliance.

P-658 NLRP3 Inflammasome and polycystic ovarian syndrome – a possible novel association

Study question

Is NLRP3 inflammasome expression in subcutaneous adipose tissue (SAT) and peripheral blood monocytes upregulated in women with polycystic ovarian syndrome (PCOS) compared to healthy controls?

Summary answer

NLRP3 expression was upregulated in subcutaneous adipose tissue but not in peripheral blood mononuclear cells (PBMCs) of women with PCOS compared to controls.

What is known already

Emerging evidence strongly suggests that PCOS is a chronic inflammatory condition. Inflammasomes are multiprotein complexes, which act as intracellular regulators of inflammation. It is now well established that NLRP3 inflammasome plays a central role in obesity-induced inflammation and insulin resistance. Given the close link between obesity and PCOS, it is plausible to hypothesize that the NLRP3 inflammasome may play a role in PCOS-related chronic inflammation and insulin resistance. This hypothesis has never been investigated before.

Study design, size, duration

This lab-based study involved reproductive age women (age 18–45years; BMI≤40kg/m2) who were diagnosed with PCOS (n = 24) according to the Rotterdam criteria. A healthy control group of non-PCOS women (n = 13) of similar age and BMI was included. Ethics approval was obtained, and all participants signed a written, informed consent. SAT biopsies were obtained during routine gynaecological surgery through the abdominal skin incision. Blood samples were obtained during surgery or during clinic visits.

Participants/materials, setting, methods

Blood samples were processed to separate plasma and to isolate peripheral blood mononuclear cells (PBMCs). SAT and PBMCs were analysed using qPCR and Western Blot (WB) to measure the relative gene and protein expression levels of NLRP3, CYP17, Caspase-1, IL-1β and IL-18 in both groups. ELISA was used to measure concentrations of Caspase-1, IL-1β and IL-18 in the plasma.

Main results and the role of chance

NLRP3 gene expression in SAT was significantly (p = 0.038) higher in PCOS women (2.08±3.5 (n = 12)) compared to controls (0.77±2.9 (n = 8)). Both groups were matched for age (PCOS, 29.4±3.7 vs controls, 30.3±4.0) and BMI (PCOS, 25.4±3.2 vs controls, 26.9±4.3). CYP17 expression was significantly (p = 0.001) higher in PCOS women (4.8±0.1) versus controls (1.5±1.6). There was a moderate positive correlation (r²=0.576, P < 0.05) between SAT NLRP3 and CYP17 expressions.

NLRP3 gene expression in PBMCs were not significantly (p < 0.05) different between non-obese PCOS (-2.64±1.55 (n = 4)), obese PCOS (-2.847±1.85 (n = 8)) and non-PCOS women (0.000±2.67 (n = 5)).

Using WB in PBMCs, NLRP3 band had a mean molecular weight of 72.59±5.43kDa with no significant difference between groups, with a trend towards higher levels in PCOS. Using ELISA in PBMCs, NLRP3 levels were not significantly (p = 0.3) different between PCOS (1.53±1.32pg/ml (n = 12)) vs controls (1.03±0.583 (n = 5)).

Gene expression levels of Caspase-1, IL-1b and IL-18 in PBMCs were not significantly (P > 0.05) different between groups.

Plasma IL-1β levels were significantly (p < 0.05) higher in PCOS (51.64±91.00ng/ml) vs. controls (0.47±0.93ng/ml). Plasma IL-18 concentrations were not significantly different between PCOS (3.79±0.53μg/ml) vs. controls (4.08±0.21μg/ml).

Limitations, reasons for caution

One limitation of this study is the lack of data on the protein expression of NLRP3 in the adipose tissue. There was also no data on other inflammasome components in the SAT analysis e.g. Caspase-1. However, all these data were available for the PBMCs.

Wider implications of the findings

The novel and interesting finding of an increase in NLRP3 in adipose tissue of PCOS women suggests that this inflammasome may play a central role in this common condition. Our study may therefore pave the way to further research to help understand the role of inflammation in PCOS

970 FRAILTY IS INVERSELY CORRELATED WITH SERUM ALBUMIN IN ACUTE HIP FRACTURE

Introduction

Frailty and sarcopenia have been shown to significantly increase the risk of falls, traumatic hip fractures and all-cause mortality in the elderly. The assessment of frailty using a validated clinical frailty scale such as that proposed by Rockwood et al., therefore, continues to remain an important step in determining post-operative prognosis in patients undergoing hip fracture surgery. The purpose of this study was to examine the relationship between frailty and serum albumin—an independent biochemical predictor of survival in hip fracture patients (1).

Method

This retrospective cross-sectional study analysed 190 patients, aged above 60 years, admitted to Queen’s Hospital Burton (QHB) between the 1st January and 28th December 2019 with a newly diagnosed hip fracture. Pre-operative serum albumin levels (g/L) and Rockwood clinical frailty scores (rCFS) were recorded from electronic medical records (EMR). Using the SPSS 27 statistical package, Pearson’s correlation co-efficient and linear regression analysis were carried out using these variables.

Results

A total of 190 patients were included in the study (57 male, 133 female). Mean patient age was 82.2 ± 8.47 years. More than 50% of patients had a Rockwood CFS ≥5. Mean serum albumin (g/L) was 37.3 ± 6.56. A statistically significant inverse correlation was demonstrated between pre-operative serum albumin levels and Rockwood CFS (r = −0.243, p < 0.001).

Conclusion

This study showed how serum albumin, a negative acute phase reactant and marker of chronic malnutrition, is inversely associated with frailty in hip fracture patients and the important role of Rockwood CFS and pre-operative serum albumin levels in the prognostication of hip fractures in the elderly.

975 RELATIONSHIP BETWEEN HAND GRIP STRENGTH (HGS) AND 10 YEAR PROBABILITY OF MAJOR OSTEOPOROTIC FRACTURES IN OLDER

Introduction

HGS has been shown to be associated with adverse outcomes in a wide range of conditions. It has also been found to be associated with bone mineral density and is inversely associated with risk of osteoporotic fractures. The aim of this study was to determine the association between HGS and 10 year probability of sustaining a major osteoporotic fractures in older inpatient and to evaluate the effect of gender on this association.

Method

This was a cross-sectional, observational analysis of older patients admitted into hospital between September and November 2021. HGS was measured in these patients using the JAMAR hydraulic hand held dynamometer. The Southampton protocol was used. The FRAX UK tool (without BMD) was used to calculate 10 year probability of major osteoporotic fractures. Patients were included if they were 60 years and above. Younger patients were excluded as were stroke patients. Patients with incomplete data were excluded from analysis. The SPSS 27 package was used for statistical analysis. Baseline characteristics were calculated using descriptive statistics. Pearson’s correlation coefficient and linear regression were used to calculate correlation.

Results

104 patients were analysed—41 males and 63 females. Mean age was 83 years (SD 8.2). Grip strength was inversely correlated with FRAX UK in predicting 10 year probability of major osteoporotic fractures in all patients, male patients and female patients (r = −0.452; p < 0.001, r = −0.351; p = 0.02 and r = −0.271; p = 0.03 respectively).

Conclusion

Grip strength is negatively associated with increased probability of major osteoporotic fractures in older inpatients. Reference(s) Ma Y, Fu L, Jia L, et al. Muscle strength rather than muscle mass is associated with osteoporosis in older Chinese adults. J Formos Med Assoc. 2018;117(2):101–108. doi:10.1016/j.jfma.2017.03.004

974 ASSOCIATION BETWEEN NOTTINGHAM HIP FRACTURE SCORE AND FRAILTY IN ELDERLY ACUTE HIP FRACTURE PATIENTS

Introduction

Nottingham Hip Fracture Score (NHFS) is a well validated risk stratification tool that has been shown to predict 30 day mortality in elderly patients with acute hip fractures. A lot of older patients that sustain hip fractures are frail. The Rockwood Clinical Frailty Scale (CFS) has been validated as a tool to screen for frailty in acutely ill patients and has been shown to predict outcomes in acutely ill elderly patients. The aim of this study was to determine if there is any correlation between the NHFS and CFS in elderly patients with acute hip fractures and to evaluate the effect of gender on this correlation.

Method

A retrospective, cross-sectional analysis was carried out on patients admitted with acute hip fractures between January and December 2019 in a single centre trauma and orthopaedic unit. Data was extracted from anonymized electronic patient records. Patients were included if they were 60 years and above; those less than 60 were excluded. Patients with missing data were excluded from analysis. NHFS and CFS were calculated in these patients. SPSS 27 IBM software was used for statistical analysis. Baseline characteristics were calculated using descriptive statistics and spearman’s correlation co-efficient and linear regression were used to determine correlation.

Results

A total of 268 patients were analysed—65 males and 202 females. Mean age was 83 years (SD 8.5). There was statistically significant positive correlation between NHFS and CFS in all patients, male patients and female patients (r = 0.589; p < 0.001, r = 0.603; p < 0.001, and r = 0.599; p < 0.001 respectively).

Conclusion

NHFS is positively correlated with CFS in elderly acute hip fracture patients. Reference(s) Doherty W.J, Stubbs T.A et al.

Pre-tracheal Ectopic Thymoma: A diagnostic challenge in Endobronchial Ultrasound-guided Transbronchial Needle Aspiration cytology

Ectopic thymomas (ETs) are rare thymic neoplasms that arise from atypical anatomical sites¹ and present a diagnostic challenge for clinicians as they can be mistaken for other pathological entities on fine needle aspiration (FNA) cytology.² Endobronchial Ultrasound-guided Transbronchial Needle Aspiration (EBUS-TBNA) sampling of mediastinal and para-tracheal lymph nodes is commonly performed to diagnose and stage lung malignancies. International literature search of thymic lesions diagnosed on EBUS-TBNA yielded only four cases although none in an ectopic location. In this report we describe a case of a patient who presented with an ectopic thymoma that was diagnosed by EBUS-TBNA from a station 4R location. Subsequent histology confirmed the diagnosis and subtyped as well as staged the tumour. We discuss the role of cytology in the diagnosis of this rare tumour from an unusual site, the potential pitfalls and highlight the importance of considering ET as a differential diagnosis in the context of unexplained mediastinal lymphadenopathy.

A104 PATIENT AND PUBLIC INVOLVEMENT (PPIN) IN IBD RESEARCH - A SCOPING REVIEW

Background

Over the past 10 years, interest in patient and public involvement (PPIn) in research has grown. Several arguments support the engagement of patients as partners in the research process. Patients with lived experience of a condition can offer their knowledge to study design as experience-based experts, helping researchers incorporate patient-pertinent outcomes. PPIn has also been shown to boost patient enrolment and retention in clinical trials. Benefits, challenges, and best practices of PPIn have been examined in other fields. However, to date, no study has examined PPIn in inflammatory bowel disease (IBD) research. Many factors amenable to research involvement may impact IBD patients’ quality of life, including disease morbidity, complications, and efficacy/side effects of therapy.

Aims

This review aims to characterize methods of PPIn in IBD research and highlight themes relating to best practices, benefits, and challenges.

Methods

We ran a systematic search on MEDLINE, EMBASE, and Cochrane for all IBD research studies in which IBD patients were involved in the research process. PPIn included but was not limited to patient input in one of the following 3 stages: Study Design (prioritization of research topics, outcome selection, study tool development), Study Execution (recruitment, data collection & analysis), and Dissemination of Research. After abstract and full-text screening, 14 studies were selected.

Results

Patients were recruited for PPIn through IBD and patient organizations (7/14), outpatient clinics (4/14), tertiary care sites (2/14), and pre-existing patient advisory groups (1/14). The majority of studies (11/14) engaged patients in the development of study materials, which included a physical activity intervention for stoma patients, an IBD pregnancy decision aid, and a quality of life questionnaire. Two studies interviewed patients to determine comprehensibility of survey items and guide revisions. One study involved patients in data analysis and manuscript development. Most consultations were open-ended, including focus groups (8/14) and semi-structured interviews (3/14). According to study authors, PPIn helps guide IBD research priorities by focusing on patient-relevant issues. Authors also cited the role of PPIn in designing patient-friendly study tools. One challenge reported by 2 studies was that PPIn requires patients to have access to high-quality information and requires a significant time commitment, which may contribute to demographic biases.

Conclusions

The majority of IBD studies engaged patients in an open-ended format and were engaged in study design, particularly in developing study materials. Authors recommend continuous involvement of patients throughout the research process to address their research priorities.

A140 INTEROBSERVER RELIABILITY OF THE PARIS CLASSIFICATION FOR SUPERFICIAL GASTROINTESTINAL TRACT NEOPLASMS: A SYSTEMATIC REVIEW AND META-ANALYSIS

Background

The Paris classification is an international classification system that characterizes the morphology of superficial gastrointestinal tract neoplasms. Given its ability to predict the risk of submucosal invasion, this tool plays an important role in the preliminary endoscopic assessment of early gastrointestinal neoplastic lesions. Despite its international prevalence, there are no pooled reliability analyses to assess agreement amongst endoscopists using this classification system.

Aims

To systematically review and meta-analyze the interobserver reliability (IOR) of the Paris classification system.

Methods

We conducted a systematic review and meta-analysis according to the PRISMA recommendations. A comprehensive literature query was conducted on biomedical databases through December 2020. Studies were included if they quantitively evaluated the IOR of the Paris classification with at least 5 endoscopists participating in the study cohort. Two authors independently screened studies and abstracted data using an a priori designed data collection form. We pooled the results of studies which provided IOR with kappa statistics and confidence intervals using DerSimonian and Laird random effects models. Risk of bias was independently assessed by two study authors using the Guidelines for Reporting Reliability and Agreement Studies (GRRAS) tool.

Results

From an initial 1541 studies, 5 were included in the qualitative review and 3 reported data that allowed for a quantitative analysis of the primary outcome, representing a total of 28 endoscopists. All three of these studies were high quality. The IOR for the Paris classification amongst all endoscopists was 0.541 (95% CI, 0.466–0.617). There was no significant improvement (p=0.551) in the IOR of the Paris classification system following an educational training intervention (pre-education pooled kappa, 0.498; 95% CI, 0.429–0.567 compared to post-education pooled kappa, 0.530; 95% CI, 0.451–0.608).

Conclusions

Interobserver reliability of the Paris classification is moderate with no significant improvement following educational intervention.

A257 PANCREATIC CANCER TREATMENT AND END OF LIFE OUTCOMES: A POPULATION BASED COHORT STUDY

Background

Patients with pancreatic cancer face challenging decisions regarding treatment choices following their diagnosis and often lack data on end-of-life (EOL) outcomes. Without the available information, older patients may be undertreated, dying earlier than they would have with treatment, while others may be overtreated and exposed to aggressive measures with harmful side effects.

Aims

To describe survival and EOL outcomes among pancreatic cancer patients based on index cancer treatment, disease stage, and patient characteristics.

Methods

We conducted a population based cohort study in Ontario, Canada of patients who died from April 2010 to December 2017 and were diagnosed with pancreatic cancer prior to death. We used administrative databases to collect data on demographics, baseline health status, treatments, and outcomes. The primary exposure was index cancer treatment (no treatment, radiation, chemotherapy alone, surgery alone, and surgery with chemotherapy). The primary outcomes were mortality, health care encounters per 30 days in the last six months of life, and palliative care visits per 30 days within the last six months of life. Secondary outcomes were location of death (institution vs. community), hospitalization within the last 30 days of life, and receipt of chemotherapy within the last 30 days of life. We estimated the association between the exposure and outcomes using multivariable models, adjusting for demographics, comorbidities, and cancer stage. Hazard ratios, adjusted mean differences, and odds ratios were reported with 95% confidence intervals.

Results

Our cohort included 9950 adults with a median age at diagnosis of 78. 56% received no index treatment, 5% underwent radiation, 27% underwent chemotherapy alone, 7% underwent surgery alone, and 6% underwent surgery and chemotherapy. In the multivariable regression (Table and Figure), radiation, chemotherapy alone, surgery alone, and surgery with chemotherapy were all associated with decreased mortality and fewer healthcare encounters. All groups except radiation were associated with fewer palliative care visits. All treatment groups were associated with lower odds of institutional death and hospitalization within the last 30 days of life, and higher odds of chemotherapy within the last 30 days of life.

Conclusions

Our data, the first to provide EOL outcome estimates based on index cancer treatment, can help patients make initial treatment decisions after a diagnosis of pancreatic cancer.

A32 DEVELOPMENT AND VALIDATION OF THE TORONTO UPPER GASTROINTESTINAL CLEANING SCORE

Background

High quality esophagogastroduodenoscopy (EGD) depends on the ability to appropriately visualize upper gastrointestinal (GI) mucosa pathology. Evaluation can be limited by the presence of mucus, foam, bubbles and solid materials. Currently, there is no standardized method to assess mucosal visualization for use in clinical or research settings.

Aims

To develop and establish the content validity of the Toronto Upper Gastrointestinal Cleaning Score (TUGCS) and evaluate its interrater reliability.

Methods

An international panel of endoscopy experts rated potential items and their associated anchors for importance as indicators of adequacy of mucosal visualization during EGD. The survey utilized a Likert scale (1 (strongly disagree) to 5 (strongly agree)). The Delphi process was repeated until consensus was reached. Consensus was defined priori as ≥80% of experts in a given round scoring ≥4 on all survey items. To assess content validity, 48 EGD procedures were evaluated in real-time by two endoscopist reviewers using the TUGCS at a single institution. The interrater agreement between assessments was calculated for TUGCS total scores using intraclass correlation coefficient, one-way random effects model (ICC 1,1).

Results

Fourteen experts agreed to be part of the Delphi panel. An anatomical framework representing the upper GI mucosa and anchors for each mucosal portion representing various levels of visibility was generated through systematic review. Three survey rounds, with response rates of 100%, 100% and 71% respectively, achieved consensus. The final TUGCS includes four anatomical areas (fundus, body, antrum, duodenum) and mucosal visualization anchors ranging from 0 to 3 (Figure 1). TUGCS was used to assess foregut cleaning in 48 procedures (Table 1). The mean TUGCS for staff and trainee were 8.1 (±2.4) and 8.1 (±2.6), respectively. The ICC was 0.78 (95% confidence interval 0.62–0.88) indicating good reliability.

Conclusions

We developed and generated content validity evidence for the TUGCS through rigorous Delphi methodology, reflective of practice across different centres. Planned as future research is a video survey distributed to endoscopists internationally to further validate the TUGCS to create a tool that may be used to judge mucosal visualization for EGD in research and clinical settings.

A89 PERCEPTIONS OF NON-TECHNICAL SKILLS IN GASTROINTESTINAL ENDOSCOPY: A THEMATIC ANALYSIS OF FOUR FOCUS GROUPS

Background

Nontechnical skills (NTS), which involve an individual’s cognitive, attitudinal, and social skills that supplement task expertise, are an essential component in the practice of gastrointestinal endoscopy. There is a growing body of literature that highlights the association between these skills and patient outcomes. To date, however, these skills have not been adequately defined within the context of gastrointestinal endoscopy.

Aims

To define the domain and corresponding characteristics of NTS in GI endoscopy.

Methods

We conducted a qualitative study at a tertiary-care academic center in Toronto, Ontario. Specifically, we held four focus groups with physician endoscopists, nurses who work in an endoscopy unit, and patients who have had previous endoscopies, in order to ascertain their input on the role of NTS in gastrointestinal endoscopy. The three groups were interviewed independently and there was one focus group of both physicians and nurses that was used for validation of our initial thematic framework. Data from the focus groups was collected using a combination of field notes and discussion transcriptions. Three authors independently generated codes from these data. Using these codes, a thematic network analysis was used to identify emerging themes. The primary outcome of this study was the development of a cohesive thematic network of NTS in endoscopy, including their characteristics and examples.

Results

The four focus groups included a total of 34 participants, including 15 physician endoscopists, 15 nurses, and 4 patients. Using thematic network analysis, we identified six dimensions of NTS using the first three focus groups: communication; professionalism; teamwork; leadership; decision-making; and situational awareness. Additional topics related to the practice and evaluation of NTS were identified. In particular, there is a degree of subjectivity in the appraisal of NTS due to the nuances among individual practice, aside from egregious errors of NTS (e.g. unprofessional behaviours). The use of video recordings was suggested as a way to capture signs of good NTS, such as appropriate levels of calmness during procedures and attention to patient comfort. Finally, patient involvement can be useful for evaluating communication and professionalism based on patient comprehension and the nature of the therapeutic relationship.

Conclusions

Our findings provide the first cohesive framework of NTS in gastrointestinal endoscopy that is anchored in real world experiences with relevant stakeholders – physicians, nurses, and patients. Future research should consolidate these findings into an assessment tool for NTS in order to evaluate and provide feedback to endoscopists who are both in training and in practice.

A25 CRITICAL APPRAISAL OF GI ENDOSCOPY CLINICAL PRACTICE GUIDELINES DURING THE COVID-19 PANDEMIC

Background

Clinical Practice Guidelines (CPGs) are integral during a pandemic, offering guidance to clinicians through uncertainty. Existing literature has established that the need for rapid publication of CPGs during previous infectious disease outbreaks resulted in less rigorous guidelines. CPGs were rapidly developed since the onset of the pandemic in December 2019, providing guidance in gastrointestinal (GI) endoscopy, an area where COVID-19 may pose risk of transmission.

Aims

To evaluate the quality of GI endoscopy guidelines developed during the COVID-19 pandemic and to compare these with (a) endoscopy CPGs developed prior to the pandemic; (b) CPGs for other endoscopic topics unrelated to COVID-19; and, (c) non-endoscopic CPGs published during the pandemic.

Methods

We systematically searched Medline, Embase and Scopus for CPGs published by GI societies from January 1, 2018 to December 31, 2020. A grey literature search was conducted. Two authors screened full-texts. In this interim analysis, CPGs were grouped based on publication year: before 2020, or 2020. Endoscopy CPGs published in 2020 were categorized as COVID or non-COVID related. Two authors independently assessed the CPGs using the AGREE II tool, consisting of six domains for evaluating guidelines. A domain score of 60 was set as a threshold to indicate good quality.

Results

There were 70 endoscopy guidelines and 27 CPGs focused on other GI topics. The mean overall scores were 69% (±12%) for endoscopy CPGs published before 2020 (n=28), and 51% (±23%) for CPGs published in 2020 (n=42). For individual AGREE II domains, mean scores for pre-2020 CPGs ranged from 33.11 (±17.39) in Applicability to 81.55 (±10.37) in Clarity of Presentation. For CPGs published during COVID-19, mean domain scores ranged from 34.18 (±10.52) in Applicability to 75.26 (±13.85) in Clarity of Presentation. 21 of 42 CPGs published in 2020 were related to COVID. Mean overall scores were 35% (±20%) for COVID-related CPGs and 67% (±13%) for non-COVID-19 CPGs. For COVID-19 CPGs, scores ranged from 27.88 (±20.31) in Rigour of Development to 69.58 (±10.81) in Scope and Purpose. For non-COVID CPGs, the scores ranged from 37.30 (±8.93) in Applicability to 84.52 (±5.93) in Clarity of Presentation.

Conclusions

The difference in overall scores between COVID-19 endoscopy CPGs and non-COVID endoscopy CPGs may suggest that the urgency to disseminate COVID-19 information decreased CPG quality or completeness of reporting. This interim analysis is limited by the lack of distinction between peer-reviewed CPGs and non-peer reviewed recommendations. Given the importance of CPGs in clinical decision making, it is important to ensure that the rapid development of guidelines does not compromise quality and rigour.

A99 PHARMACEUTICAL INDUSTRY FUNDING TO GASTROINTESTINAL PATIENT ADVOCACY ORGANIZATIONS

Background

Patient advocacy organizations (PAOs) are not-for-profit organizations that aim to support families and individuals afflicted by illnesses. PAOs play a significant role in guiding health policy, providing education to patients, lobbying, and supporting research. Previous studies have demonstrated that PAOs may receive financial payments from pharmaceutical and medical device manufacturers. This may create a risk of conflict of interest.

Aims

To assess the prevalence and transparency of financial donations from industry to gastrointestinal patient advocacy groups based in the United States (US).

Methods

We conducted a cross-sectional study to determine the prevalence of industry donations to PAOs. Data was extracted from the Kaiser Health News (KHN) Database, a database that tracked payments from pharmaceutical companies to PAOs in 2015. After an initial list of 1215 PAOs was obtained from the database, authors extracted the annual revenues, websites and mission statements for each PAO. Authors individually screened each organization’s mission statement and website to determine whether their primary scope of focus included gastroenterology. A final list of 11 PAOs with annual revenues surpassing $500,000 USD was included for descriptive analysis. From this list, the annual reports and websites of each group were reviewed to determine the extent of transparency of PAOs disclosing financial relationships with industry sponsors. The primary outcome of our study was the total amount of funding that each PAO received from pharmaceutical companies. The secondary outcome was the self-reported amount of funding stated on each PAO’s website and annual report.

Results

From our analysis of 11 PAOs, 9 (81%) organizations received payments from pharmaceutical companies. The median dollar value of donations received was $31,052 USD (IQR=$25 to $302,550). The total dollar value of donations received was $4,059,433 USD. Across the 9 PAOs that received donations, 5 (56%) organizations disclosed a financial relationship with a pharmaceutical company on their website and 2 (22%) disclosed the value of industry donations within a range. No group specified an exact amount of funding received.

Conclusions

Our results demonstrate that a majority of US based gastrointestinal PAOs receive funding from pharmaceutical companies. Furthermore, our results show that many PAOs that receive industry funding do not disclose this amount on their website or annual reports. Given their role in providing patient centered support, it is important for PAOs to disclose financial relationships with industry so as to not produce a conflict of interest.

Neonatal myocardial infarction due to coronary thrombus is a rare cause of acute heart failure and is associated with high morbidity and mortality. We present a rare case of a full-term newborn who developed coronary artery thrombus treated with intracoronary recombinant tissue plasminogen activator infusion while undergoing therapeutic hypothermia. Also, we describe a unique treatment strategy to support systemic circulation sparing the patient from neonatal extracorporeal membrane oxygenation and its complications. Neonatal myocardial infarction should be suspected and ruled out in sick newborns.

Prevalence of cestodes infection among school children of urban parts of Lower Dir district, Pakistan

Tapeworms of zoonotic importance have been described as a leading public health problem. Current research was aim to assess the prevalence of tapeworms among 5-12years school children residing in district Lower Dir, Pakistan from January 2019-December 2019. The wet mount preparation in saline/iodine/methods were used for stool examination. Data was analyzed using appropriate descriptive, static methods. Of the 400 children studied 71.7% were infected with one or more species of intestinal parasites. Single infection of cestode species was found in 69 individuals with 17.2% prevalence and multiple parasitic infections were identified in 19.7% (n=79/400) individuals. The multiple infection were comprised as 10% (n=40) double, 6.75% (n=27) triple and 3% (n=12) quadruple. A total of 9 species of helminths and one species of protozoan infection. Among the helminths Ascaris lumbricoides was the most prevalent 33.1% (n=95), Taenia saginata 22.6% (n=65), hookworm 19.8% (n=57), Hymenolepis nana 18.8% (n=54), Enterobius vermicularis and Hymenolepis diminuta 1.39% (n=4each), Trichuris trichura 1.04% (n=3), Toxocara spp 0.69% (n=2) and Schistosoma japonicum 0.34% (n=1) were reported. One protozoan species was Cryptosporidium spp 0.69% (n=2) in current study. In case of A.lumbricoides, hookworm, E.vermicularis, T.trichura, T.saginata, H.nana and H.diminuta the male children of below 8 years of age were highly infected. Other infections are reported in the same prevalence with slight difference if any. We conclude that there is a need for mass scale campaigns to create awareness regarding health and hygiene in children and the need for development of effective poverty control programs because deworming alone is not adequate to control parasitic infections.

Aims To review the evidence regarding the possibility of fetal vertical transmission in COVID-19 positive pregnant mothers by diagnosing through placental swabs. Methods The search terms 'pregnant COVID-19 positive mothers', 'fetal vertical transmission' and 'placental swabs' were used. 20 papers were selected. Results 183 COVID-19 positive pregnant women were identified whose 184 placentas and 185 neonates were also analysed by RT-PCR or immunohistochemistry and/or in situ hybridization for the presence of SARS-CoV-2 (one case of monochorionic diamniotic twins and one case of dichorionic diamniotic twins). 183 liveborn neonates were successfully delivered primarily via caesarean section (99%). 2 mothers did not deliver liveborn infants due to severe preeclampsia resulting in a termination of pregnancy and a miscarriage, both occurring in the second trimester. 9 neonates tested positive for SARS-CoV-2 (5%). We report no neonatal mortality after live birth and no maternal mortality. 17 placentas tested positive for SARS-CoV-2 out of a total of 184 tested (9%). Of these 17, 7 cases of SARS-CoV-2 were identified in the maternal, neonatal and placental tissue. Conclusion There is no concrete evidence of vertical transmission occurring between mother and infant. We propose further research investigating the effects of COVID-19 on pregnant women by using RT-PCR to test the mother, placenta, vaginal fluid, breast milk and infant for SARS-CoV-2 at various stages of transmission.

Morphology of the entering and exiting nerve as a differentiating feature of benign from malignant peripheral nerve sheath tumours of the brachial plexus

OBJECTIVE

To identify if morphology of the entering and exiting nerve involved by a nerve sheath tumour in the brachial plexus can help differentiate between benign (B) and malignant (M) peripheral nerve sheath tumours (PNSTs).

MATERIALS AND METHODS

Retrospective review of 85 patients with histologically confirmed primary PNSTs of the brachial plexus over a 12.5-year period. Clinical data and all available MRI studies were independently evaluated by 2 consultant musculoskeletal radiologists blinded to the final histopathological diagnosis assessing for maximal lesion dimension, visibility and morphology of the entering and exiting nerve, and other well-documented features of PNSTs.

RESULTS

The study included 47 males and 38 females with mean age 46.7 years (range, 8-81 years). There were 73 BPNSTs and 12 MPNSTs. The entering nerve was not identified in 5 (7%), was normal in 17 (23%), was tapered in 38 (52%) and showed lobular enlargement in 13 (18%) BPNSTs compared with 0 (0%), 0 (0%), 2 (17%) and 10 (83%) MPNSTs respectively. The exiting nerve was not identified in 5 (7%), was normal in 20 (27%), was tapered in 42 (58%) and showed lobular enlargement in 6 (8%) BPNSTs compared with 4 (33%), 0 (0%), 2 (17%) and 6 (50%) MPNSTs respectively. Increasing tumour size, entering and exiting nerve morphology and suspected MRI diagnosis were statistically significant differentiators between BPNST and MPNST (p < 0.001). IOC for nerve status was poor to fair but improved to good if normal/tapered appearance were considered together with improved specificity of 81-91% for BPNST and sensitivity of 75-83%.

CONCLUSIONS

Morphology of the adjacent nerve is a useful additional MRI feature for distinguishing BPNST from MPNST of the brachial plexus.

A104 PREVALENCE OF GHOST-AUTHORSHIP IN INDUSTRY-SPONSORED CLINICAL TRIALS

Background

Ghost-authorship involves the exclusion of individuals who have made substantial contributions to the article from the author byline. Previous studies have found that ghost-authorship is highly prevalent in industry-sponsored clinical trials. Its prevalence, however, has yet to be investigated in trials of biologics in the management of inflammatory bowel disease (IBD).

Aims

To determine the prevalence of ghost-authorship in IBD biologic industry-sponsored clinical randomized controlled trials (RCTs).

Methods

Biologic medications indicated for ulcerative colitis (UC) or for Crohn’s disease (CD) were identified using the Food and Drug Agency (FDA) database. We identified the clinical trials on clinicaltrials.gov corresponding to the data presented at the time of FDA approval. Specifically, we included the first publication for each trial to report study results for our analysis. Two authors independently identified the presence of ghost-authorship, which we defined as the exclusion on the author byline of the included RCT publication of any individuals who assisted in the writing of the trial manuscript and/or performed the data analyses.

Results

We identified a total of 28 relevant RCTs on biologic medications (10 for UC and 18 for CD), which were matched to 20 publications. We found ghost-authorship in 70% of publications (n=14); 40% (n=8) involved manuscript and protocol writing assistance from sponsor staff; 35% (n=7) involved medical writers from external companies; 15% (n=3) involved both sponsor staff and medical writers assisting in manuscript writing; and 20% (n=4) involved individuals performing data analysis or interpretation.

Conclusions

We found that ghost-authorship in industry-sponsored IBD biologic clinical trials has a moderately high prevalence, with the most common being manuscript or protocol writing assistance. A lack of transparency regarding sponsor-affiliated and/or external contributors may negatively affect the trust placed in medical research. One limitation is that data was only extracted from publications. Further evidence on ghost-authorship may be found in study protocols and registrations, which will be investigated in the future.

A97 TOOLS FOR DIRECT OBSERVATION AND ASSESSMENT OF COLONOSCOPY: A SYSTEMATIC REVIEW OF VALIDITY EVIDENCE

Background

An increasing focus on quality and safety in colonoscopy has led to broader implementation of competency-based educational systems that enable documentation of trainees’ achievement of the knowledge, skills, and attitudes needed for independent practice. The meaningful assessment of competence in colonoscopy is critical to this process. While there are many published tools that assess competence in performing colonoscopy, there is a wide range of underlying validity evidence. Tools with strong evidence of validity are required to support feedback provision, optimize learner capabilities, and document competence.

Aims

We aimed to evaluate the strength of validity evidence that supports available colonoscopy direct observation assessment tools using the unified framework of validity.

Methods

We systematically searched five databases for studies investigating colonoscopy direct observation assessment tools from inception until April 8, 2020. We extracted data outlining validity evidence from the five sources (content, response process, internal structure, relations to other variables, and consequences) and graded the degree of evidence, with a maximum score of 15. We assessed educational utility using an Accreditation Council for Graduate Medical Education framework and methodological quality using the Medical Education Research Quality Instrument (MERSQI).

Results

From 10,841 records, we identified 27 studies representing 13 assessment tools (10 adult, 2 pediatric, 1 both). All tools assessed technical skills, while 10 assessed cognitive and integrative skills. Validity evidence scores ranged from 1–15. The Assessment of Competency in Endoscopy (ACE) tool, the Direct Observation of Procedural Skills (DOPS) tool, and the Gastrointestinal Endoscopy Competency Assessment Tool (GiECAT) had the strongest validity evidence, with scores of 13, 15, and 14, respectively. Most tools were easy to use and interpret and required minimal resources. MERSQI scores ranged from 9.5–11.5 (maximum score 14.5).

Conclusions

The ACE, DOPS, and GiECAT have strong validity evidence compared to other assessments. Future studies should identify barriers to widespread implementation and report on use of these tools in credentialing purposes.

A160 PREVALENCE OF OUTCOME SWITCHING AMONG PUBLISHED PHASE 3 INTERVENTIONAL TRIALS FOR INFLAMMATORY BOWEL DISEASE THERAPEUTICS

Background

Outcome switching is a well-described form of inconsistent reporting in randomized clinical trials (RCTs), wherein pre-specified primary and/or secondary outcomes are changed between trial registration and the publication of results without explanation. This is of particular concern, as the selective publication of results that are favorable will insert bias into the trial’s results and may cast doubt on the veracity of its findings. While it has been investigated in other disciplines, the prevalence of outcome switching has yet to be described among RCTs for inflammatory bowel disease (IBD).

Aims

To determine the prevalence of correctly reported pre-specified primary and secondary outcomes in published phase 3 interventional RCTs for IBD.

Methods

We identified all phase 3 interventional trials for IBD with published results using clinicaltrials.gov. We included all results with an associated publication that detailed the results of the trial. We excluded registrations if: only an abstract of the results was available; trial results were only published as a pooled analysis; multiple trial segments were reported collectively; or a publication of the results could not be identified through clinicaltrials.gov or a custom search.

Two reviewers extracted all pre-specified primary and secondary outcomes for each trial using the clinical trial registration page that was dated before the commencement of the trial. These outcomes were compared to the outcomes reported in the corresponding journal articles. Any discrepancies were noted, and additional outcomes were extracted.

Results

We identified a total of 88 phase 3 interventional RCTs for IBD, of which 57 were matched to independent publications of their results. All trials pre-specified a primary outcome, and 50 (87.7%) pre-specified secondary outcomes. 10 (17.5%) of trials did not report some or all primary outcomes, and 19 (33.3%) trials had a change or alteration to the primary outcome. Of the trials that pre-specified secondary outcomes, 16 (28.1%) did not report all pre-specified secondary outcomes. 49 (86.0%) trials added 6 (IQR: 2–8) unspecified secondary outcomes on average.

Conclusions

Many phase 3 interventional RCTs in IBD either did not report some or all primary outcomes, or altered the primary outcome. Trials routinely reported additional outcomes that were not pre-specified and failed to note that they were added post hoc. Based on these results, we recommend improvements in the reporting of pre-specified outcomes and higher fidelity in order to maintain confidence in trial results.

A70 PREVALENCE OF SELF-PUBLICATION AMONG EDITORIAL BOARD MEMBERS OF GASTROENTEROLOGY JOURNALS

Background

Editorial self-publication refers to the practice wherein editors publish research in journals to which they serve as editorial board members. The International Committee of Medical Journal Editors (ICMJE) has detailed recommendations against the practice of self-publication. There is evidence to suggest that editorial board membership may influence the decision to publish academic papers, which may contribute to publication bias. Despite this, there have been few attempts to characterize this practice in gastroenterology journals.

Aims

To determine the prevalence of original gastroenterology research articles published by editorial board members in their own journal.

Methods

We conducted a cross-sectional study to determine the prevalence of editorial board members publishing within their own journals. A list of the top 25 highest impact factor gastroenterology journals was created through InCites Journal reports. Journals were screened to determine eligibility based on whether their primary focus included gastroenterology research and whether archives with the names and affiliations of editorial board members were available. 10 journals were selected based on these criteria. For each journal, we extracted all original research articles published in 2019 using Web of Science (Clarivate Analytics ©). Articles classified as editorial material, meeting abstracts, reviews, and clinical practice guidelines were excluded. We cross-referenced the affiliations of all authors found in each publication with affiliations of editors disclosed on the journal website. For each editorial board member, we determined the number of publications within their own journal.

Results

We identified 844 editorial board members in the 10 journals included. Overall, 337 (39.9%) of the editors had a publication in their own journal, of which, 152 (18.0%) had more than one publication. Across all journals, the median number of editors with self-publication is 27 (IQR=20.3–49.8). The median number of editors with more than one self-publication is 16 (IQR=10.0–25.3). In total, 507 (60.1%) of all editors had no publications within their respective journals.

Conclusions

Despite recommendations against this practice, our results show a high number of research publications authored by editorial board members. These results demonstrate a potential risk for publication bias. However, this study was limited by the inability to investigate beyond the prevalence of self-publication. Furthermore, the explicit implications of our results remain unclear. Further research is required to evaluate factors such as disclosures and the review process associated with increased rates of self-publication as well as its impact on publication bias.
