Abstract
BACKGROUND Prevalence of depression is increasing in young people, and there is a need to develop and evaluate behavioural interventions which may provide benefits equal to or greater than talking therapies or pharmacological alternatives. Exercise could be beneficial for young people living with depression, but robust, large-scale trials of effectiveness and the impact of exercise intensity are lacking. This study aims to test whether a randomised controlled trial (RCT) of an intervention targeting young people living with depression is feasible by determining whether it is possible to recruit and retain young people, develop and deliver the intervention as planned, and evaluate training and delivery. METHODS The design is a three-arm cluster randomised controlled feasibility trial with embedded process evaluation. Participants will be help-seeking young people, aged 13-17 years experiencing mild to moderate low mood or depression, referred from three counties in England. The intervention will be delivered by registered exercise professionals, supported by mental health support workers, twice a week for 12 weeks. The three arms will be high-intensity exercise, low-intensity exercise, and a social activity control. All arms will receive a 'healthy living' behaviour change session prior to each exercise session and the two exercise groups are energy matched. The outcomes are referral, recruitment, and retention rates; attendance at exercise sessions; adherence to and ability to reach intensity during exercise sessions; proportions of missing data; adverse events, all measured at baseline, 3, and 6 months; resource use; and reach and representativeness. DISCUSSION UK National Health Service (NHS) policy is to provide young people with advice about using exercise to help depression but there is no evidence-based exercise intervention to either complement or as an alternative to medication or talking therapies. UK National Institute for Health and Care Excellence (NICE) guidelines suggest that exercise can be an effective treatment, but the evidence base is relatively weak. This feasibility trial will provide evidence about whether it is feasible to recruit and retain young people to a full RCT to assess the effectiveness and cost-effectiveness of an exercise intervention for depression.

Abstract
Context
Overseas studies have quantified production differences of Hereford × Angus compared with purebred Angus for a range of traits including growth, carcass and reproductive traits.
Aim
This study aims to provide a comparison of Hereford × Angus and purebred Angus under modern grazing conditions in southern Australia.
Methods
Thirty Hereford and 22 Angus sires were mated to 1100 Angus cows and heifers in a large commercial herd run on pasture at Musselroe Bay, Tasmania. Approximately 1650 calves were born. Steers were grown on pasture for an average of 23 months and then slaughtered.
Results
Hereford sired calves were heavier at birth (+8.8%) and weaning (+4.1%). Hereford-sired calves from heifers (but not from mature cows) had more assisted births (+8.2%) and more calf deaths (10.0% vs 5.1%). Hereford-sired steers had higher hot standard carcass weight (+4.1%) and eye-muscle area (+3.2%) but when hot standard carcass weight was fitted as a covariate, eye-muscle area was no longer significant. Carcass quality measures (AUSMEAT marbling –25.8%, Meat Standards Australia marbling –10.5%, Meat Standards Australia index –1.0%) were poorer for Hereford-sired steers and fat colour (+6.9%) was darker. Meat samples from Hereford-sired steers had significantly lower colour indicators (L and b). There was no difference in cooking loss and shear force, and intramuscular fat was lower (3.0% vs 4.1%).
Conclusions
Hereford × Angus calves were heavier at birth than were purebred Angus, but had more calving difficulty and deaths associated with heifer dams. Hereford × Angus carcasses were heavier but had lower indicators of quality than did purebred Angus.
Implications
As Hereford × Angus steers produced a 4.1% heavier carcass, pure Angus steers would need to attract a premium of at least 4.1% for the additional marbling to give more value. Hereford bulls could be mated to Angus cows and not Angus heifers to avoid calving difficulties. Alternatively, good calving Hereford bulls could be selected using estimated breeding values when mating to Angus heifers.

Abstract
OBJECTIVE To conduct patient and public involvement (PPI) to gain insight into the experience of healthy eating and weight management advice during pregnancy. DESIGN PPI in the planning and development of health interventions, aiming to ensure patient-centred care. Optimum nutrition and weight management are vital for successful pregnancy outcomes, yet many services report poor attendance and engagement. SETTING Community venues in Liverpool and Ulster (UK). PARTICIPANTS Two PPI representatives were involved in all aspects of the study: design, interview questions, recruitment and collection/analysis of feedback. INTERVENTION Feedback was collected via note taking during group discussions, two in Liverpool (n = 10 & 5); two in Ulster (n = 7 & 9) and an interview (n = 1, in Ulster). MAIN OUTCOME MEASURES Transcript data were collated and thematic analysis was applied in analysis. RESULTS Thematic analysis identified three themes: (i) weight gain is inevitable in pregnancy; (ii) healthy eating advice is important but currently lacks consistency and depth and (iii) expectations regarding the type of knowledge/support. CONCLUSIONS PPI provides opportunity to enhance research design and offers valuable insight towards the needs of healthcare users. Pregnant women want positive health messages, with a focus on what they can/should do, rather than what they should not do. Midwives need to consider their communication with pregnant women, to ensure that their unique relationship is maintained, especially when the topics of diet and weight management are addressed. A well-designed digital intervention could improve access to pregnancy-specific nutrition information; empowering midwives to communicate patient-centred, healthy eating messages with confidence. This has the potential to change dietary and weight management behaviour in pregnant women.

Abstract
BACKGROUND Cutaneous squamous cell carcinoma (cSCC) is a common cancer that invades the dermis through the basement membrane. The role of the basement membrane in poorly differentiated cSCC is not well understood. OBJECTIVES To study the effect that loss of the laminin subunit alpha-3 (α3) chain from the tumour microenvironment has on tumour invasion and inflammatory cell recruitment. METHODS We examined the role of the basement membrane proteins laminin subunits α3, β3 and γ2 in SCC invasion and inflammatory cell recruitment using immunohistochemistry, short hairpin RNA knockdown, RNA-Seq, mouse xenograft models and patient tumour samples. RESULTS Analysis of SCC tumours and cell lines using antibodies specific to laminin chains α3, β3 and γ2 identified a link between poorly differentiated SCC and reduced expression of laminin α3 but not the other laminin subunits investigated. Knockdown of laminin α3 increased tumour invasion both in vitro and in vivo. Western blot and immunohistochemical staining identified increased phosphorylated myosin light chain with loss of laminin α3. Inhibition of ROCK (rho-associated protein kinase) but not Rac1 significantly reduced the invasive potential of laminin α3 knockdown cells. Knockdown of laminin subunits α3 and γ2 increased monocyte recruitment to the tumour microenvironment. However, only the loss of laminin α3 correlated with increased tumour-associated macrophages both in xenografted tumours and in patient tumour samples. CONCLUSIONS These data provide evidence that loss of the laminin α3 chain in cSCC has an effect on both the epithelial and immune components of cSCC, resulting in an aggressive tumour microenvironment.

Abstract
Volcanic emissions are a critical pathway in Earth's carbon cycle. Here, we show that aerial measurements of volcanic gases using unoccupied aerial systems (UAS) transform our ability to measure and monitor plumes remotely and to constrain global volatile fluxes from volcanoes. Combining multi-scale measurements from ground-based remote sensing, long-range aerial sampling, and satellites, we present comprehensive gas fluxes-3760 ± [600, 310] tons day-1 CO2 and 5150 ± [730, 340] tons day-1 SO2-for a strong yet previously uncharacterized volcanic emitter: Manam, Papua New Guinea. The CO2/ST ratio of 1.07 ± 0.06 suggests a modest slab sediment contribution to the sub-arc mantle. We find that aerial strategies reduce uncertainties associated with ground-based remote sensing of SO2 flux and enable near-real-time measurements of plume chemistry and carbon isotope composition. Our data emphasize the need to account for time averaging of temporal variability in volcanic gas emissions in global flux estimates.

Abstract
Postoperative pain is an outcome of importance to potential living kidney donors (LKDs). We prospectively characterized the prevalence, severity, and patterns of acute or chronic postoperative pain in 193 LKDs at six transplant programs. Three pain measurements were obtained from donors on postoperative Day (POD) 1, 3, 7, 14, 21, 28, 35, 41, 49, and 56. The median pain rating total was highest on POD1 and declined from each assessment to the next until reaching a median pain-free score of 0 on POD49. In generalized linear mixed-model analysis, the mean pain score decreased at each pain assessment compared to the POD3 assessment. Pre-donation history of mood disorder (adjusted ratio of means [95% confidence interval (CI)]: 1.40 [0.99, 1.98]), reporting "severe" on any POD1 pain descriptors (adjusted ratio of means [95% CI]: 1.47 [1.12, 1.93]) and open nephrectomy (adjusted ratio of means [95% CI]: 2.61 [1.03, 6.62]) were associated with higher pain scores across time. Of the 179 LKDs who completed the final pain assessment, 74 (41%) met criteria for chronic postsurgical pain (CPSP), that is, any donation-related pain on POD56. Study findings have potential implications for LKD education, surgical consent, postdonation care, and outcome measurements.

Abstract
BACKGROUND Mozambique has one of the highest incidence rates of both TB and HIV in the world and an estimated tuberculosis (TB) treatment coverage of only 57% in 2018. Numerous approaches are being tested to reduce existing gaps in coverage and the estimated number of missing cases. METHODS Thirty Community Healthcare Workers (CHWs) were tasked with increasing TB notifications by performing verbal facility-based TB screening of all people presenting for care and TB contact tracing in the community. Using routine National TB Program data, we analyzed trends in TB notifications in five intervention districts and seven control districts in Manica province the year before this project and during a one-year intervention period. RESULTS In the four quarters before the study, the intervention districts notified 5,219 individuals with all forms of TB, and the control districts notified 2,248 TB cases. During the study 5,982 all forms of people with TB were notified in the intervention area, an increase of 763 (14.6%) over the baseline, whereas the control districts notified 1,877 persons with TB, a decrease of -371 (-16.5%). The CHW screening activities yielded 1,502 notified and treated individuals with TB. CONCLUSIONS Employing CHWs to promote facility-based TB screening and household contact tracing may lead to an overall increase in TB notification.

Abstract
The Vitamin D External Quality Assessment Scheme (DEQAS) distributes serum samples globally, on a quarterly basis, to assess participants' performance of specific methods for 25-hydroxyvitamin D (25OHD) and 1,25-dihydroxyvitamin D (1,25-(OH)2D). DEQAS occasionally circulates samples containing high levels of substances found in certain clinical situations e.g. 25-OHD2, 24,25-(OH)2D3, hypertriglyceridemia. The increased availability and use of health supplements containing biotin has led to case reports of assay interference in methods utilizing a biotin-streptavidin detection system. In October 2018, DEQAS included a serum sample (545) containing exogenous biotin (concentration =586 μg/L) which was analyzed by a total of 683 laboratories using 35 different methods. The same serum sample (544) without exogenous biotin was also included in the 5-sample set. All methods (760 laboratories) performed satisfactorily on sample 544 giving an All-Laboratory Trimmed Mean = 50.2 ± 6.5 nmol/L (±SD, CV = 12.9 %). The target value for this sample 544 (& 555) was 47.4 nmol/L as determined by Centers for Disease Control and Prevention (CDC) Atlanta, Georgia using their LC-MS/MS reference method. In contrast, #545 containing the exogenous biotin was reported by only 683 laboratories and gave an All-Laboratory Trimmed Mean = 66.8 ± 37.6 nmol/L (±SD, CV = 56.3 %). As expected, LC-MS/MS methods (143 labs) reported similar results for both 544 = 48.9 ± 4.4 nmol/L (±SD) and 545 = 48.3 ± 4.5 nmol/L (±SD) showing that assays involving chromatographic steps are unaffected by the presence of biotin. Several of the antibody-based assays including Abbott Architect, DiaSorin Liaison, Beckman Unicel and Siemens Centaur are also unaffected by the addition of biotin. Two assays, IDS-iSYS and Roche Total 25OHD, both of which use biotin-streptavidin, exhibit biotin interference yielding values with a significant positive bias for 545 of 102.6 nmol/L ± 78.7 nmol/L (±SD) and 517.8 nmol/L ± 209.8 nmol/L (±SD) respectively. Interestingly, the failure to report sample 545 data from 77 laboratories is due solely to those running Roche Total 25OHD or Roche Vitamin D Total II assays. Given the prevalence of the adversely affected assays (25 % of DEQAS users) and the high volume of 25OHD testing, clinicians using these assays should, where possible, only measure 25OHD when patients are off biotin.

Abstract
BACKGROUND Due to the high incidence and demographic development, there is an urgent need for healthcare research data on lower urinary tract symptoms due to benign prostatic hyperplasia (LTUS/BPH). Since 2005 the Governing Body of German Prostate Centers (DVPZ) has been collecting data from 22 prostate centers in order to determine the quality and type of cross-sectoral care in particular for LUTS/BPH patients. OBJECTIVES Presentation of the DVPZ database in general, as well as an investigation of treatment patterns for medical and instrumental therapies. MATERIALS AND METHODS The analysis is based on UroCloud data sets from 30 November 2017. In the UroCloud data on diagnostics, therapy and course of disease are recorded in a web-based manner. RESULTS A total of 29,555 therapies were documented for 18,299 patients (1.6/patient), divided into 48.5% instrumental, 29.2% medical treatment, and 18.0% "wait and see" (in 4.3% no assignment was possible). Patients treated with an instrumental therapy were oldest (median: 72 years, interquartile range: 66-77), had the largest prostate volumes (50 ml, 35-75 ml), and were mostly bothered by symptoms (International Prostate Symptom Score = 19/4). The majority of patients under medical treatment received alphablockers (56%); phytotherapeutics were used least frequently (3%). Instrumental therapies are dominated by transurethral resection (TUR) of the prostate (60.0%), open prostatectomy (9.4%) and laser therapy (5.0%), with laser therapy having the shortest hospital stay (5 days) and the lowest transfusion and re-intervention rates (1.0% and 4.6%, respectively). CONCLUSIONS The DVPZ certificate covers the complete spectrum of cross-sectoral care for LUTS/BPH patients and documents the use of the various therapies as well as their application and effectiveness in the daily routine setting.

Abstract
Background In the ongoing debate on optimum methods for identification of Indigenous people within linked administrative data, few studies have examined the impacts of method on population counts and outcomes in family-based linkage studies of Aboriginal children. Objective To quantify differences between three algorithms in ascertaining Aboriginal and Torres Strait Islander children in linked administrative data. Methods Linked administrative health data for children born in Western Australia (WA) from 2000-2013, were used to examine the cohorts identified by three methods: A) the Indigenous Status Flag (ISF, derived by the WA Data Linkage Branch using a multistage-median approach) for the children alone; B) the ISF of the children, their parents and grandparents; and C) Indigenous status of the child, mother or father on either of the child's perinatal records (Midwives or birth registration), to determine differing characteristics of each cohort. Results Method B established a larger cohort (33,489) than Method C (33,306) and Method A (27,279), with all methods identifying a core group of 26,790 children (80-98%). Compared with children identified by Method A, additional children identified by Methods B or C, were from less-disadvantaged and more urban areas, and had better perinatal outcomes (e.g. lower proportions of small-for-gestational age, 10% vs 16%). Differences in demographics and health outcomes between Methods C and B were minimal. Conclusions Demographic and perinatal health characteristics differ by Aboriginal identification method. Using perinatal records or the ISF of parents and grandparents (in addition to the ISF of the child) appear to be more inclusive methods for identifying young Indigenous children in administrative datasets.

Abstract
Background
Patients living with chronic illnesses require long-term and often repeated interactions with the healthcare system. Inflammatory Bowel Disease (IBD) is an incurable, chronic gastrointestinal disease which frequently flares and remits. The nurse navigator (NN) serves as the point of first contact for IBD connecting patients with their multidisciplinary care team in order facilitate and expedite assessment, treatment and navigation through the healthcare system with the goal of improving disease-related outcomes while reducing healthcare system burden.
Aims
The aim of this study was to assess the impact of implementation of an IBD NN role within a multidisciplinary IBD Medical home on access to care, disease related outcomes, patient satisfaction with care, and healthcare resource use.
Methods
This was a retrospective cohort study comparing an IBD patient population that had access to a 24/7 NN-led helpline to a reference population who did not have access to such a service. Data between August 2017 and October 2019 were extracted from patient charts. Distribution of number of flares and time to clinical assessment between the NN exposed cohort and a non-NN exposed cohort are planned using multivariate analysis. This is a preliminary description of the NN-exposed cohort only.
Results
Preliminary results identified a total of 643 patients in the NN-exposed cohort. The majority of our NN-exposed population were female (64.3%). The mean age was 46.42 ± 16.86 years. Sixty-five percent of patients had CD, 33% UC and 2% IBDU. Of the 729 calls extracted, care coordination (39%) was the most frequent indication for calls followed by flare (25%), and medication education (16%). Patients made the majority (52.8%) of calls compared to NN initiated calls (47.2%). The mean number of calls per patient was 2.64 ± 2.51 (range 1–18) during the study period. Time to clinic assessment post flare call was on average 10.22 ± 8.51 days.
Conclusions
These results are descriptive of the NN-exposed cohort. Data comparing outcomes amongst the NN-exposed cohort to the non-exposed cohort will be presented at CDDW.

Abstract
Abstract
Background
Canada has the highest global age-adjusted incidence and prevalence rates of Inflammatory Bowel Disease (IBD). Resulting from compounding prevalence and limited resources, timely access to specialty care is a challenge faced by patients and healthcare providers. Despite this issue, there has been no published research elucidating the patient perspective using qualitative approaches to compare and contrast the patient experience across Canada.
Aims
To elicit a qualitative data stream to better understand phenomena related to access to healthcare for Canadians living with IBD from a patient-centered perspective.
Methods
Patients diagnosed with IBD (≥18 years of age) were recruited from gastroenterology clinics and communities through IBD specialists and Crohn’s & Colitis Canada. To ensure geographic diversity and representation, patients were recruited from urban and rural regions. In order to acquire multiple access perspectives, patients were invited to bring a family member who was involved in their care to the focus groups. Co-facilitated by a researcher and a patient research partner, the focus groups were held in Nova Scotia, New Brunswick, Quebec, Ontario, Manitoba, Saskatchewan, and British Columbia. All focus groups were audio recorded, transcribed, and coded for themes. Themes were distilled through qualitative thematic analysis using Atlas.ti software to ascertain congruence or discordance of IBD specialty care access experiences.
Results
A total of 63 participants were recruited in fourteen focus groups across seven provinces. The majority of participants were female (41/63, 65%) and from urban/suburban regions (34/63, 54%). The mean age of participants was 48 years (SD=16 years, range=16 to 77 years). Preliminary analyses illustrated three patient-identified access barrier themes: 1) Lack of multidisciplinary care (psycho-social and nutrition support), 2) Diagnostic delay, and 3) Inability to effectively receive and provide communication with healthcare providers. In response, four solutions were proposed: 1) Integration of holistic care into the clinical practice, 2) Readily accessible psycho-social and nutritional support, 3) Increased patient advocacy, and 4) Continuity and liaison through provision of a healthcare navigator resource.
Conclusions
The complexity of specialty care access for IBD patients in Canada cannot be underestimated. It is vital to possess a robust understanding of healthcare system structures, processes, and the significant impact these factors have on patients and the care received. Through the use of patient-centered exploration of barriers and facilitators, access to IBD specialty care in Canada can be better understood and improved on both a provincial and national scale.

Abstract
Abstract
Background
Inflammatory Bowel Disease (IBD) is a class of chronic immune-mediated diseases. Biologics have revolutionized the treatment of IBD. Existing literature suggests significant variation exists in the use of biologic treatment among physicians, from provider-specific prescribing to completion of the pre-biologic workup. These differences may influence the effectiveness of achieving and maintaining long-term remission. Clinical care pathways may serve to standardize the use of biologics in the treatment of IBD leading to improvements in patient outcomes and consistency of care provided from different specialists.
Aims
To determine if the use of biologics to treat IBD managed within a standardized biologic care pathway (BCP) is safer and more effective compared to the current standard of care.
Methods
This was a retrospective, real-world cohort study of a prospectively implemented evidence-based BCP at the Nova Scotia Collaborative IBD (NSCIBD) program between 2015 and 2019. Patient inclusion criteria consisted of any adult with a diagnosis of IBD (including Crohn’s Disease, ulcerative colitis, IBD-Unclassified) aged 18 years or older who was managed within the NSCIBD program. Preliminary descriptive analyses of the data are presented. Data collection is ongoing and multivariate analyses will be presented in full at CDDW.
Results
In total 249 patients were included in the cohort study (111 BCP patients, 138 non-BCP patients). The mean age was 49 years (range of 17–86 years). Sixty-nine percent (171/249) of patients were diagnosed with CD, 28% (70/249) with UC, and 3% (8/249) with IBD-U. The mean duration of disease was 13 years (range of 0–36 years). Use of combination therapy was similar between the cohorts with 64% of BCP patients (n=102) and 63% of non-BCP patients (n=123) on combination therapy. Thirty-eight percent of the BCP cohort required dosing interval changes vs. 29% in the non-BCP cohort (0.24 fold higher in BCP cohort). Seventy-one percent of the BCP patients were exposed to TDM vs. 41% of the non-BCP cohort (0.40-fold more TDM in pathway cohort). Although 34% of BCP patients and 38% of non-BCP cohort patients reached clinical remission (n=103 and 125, respectively), 38% of BCP patients and 21% of non-BCP patients achieved endoscopic remission (0.5-fold lower in the non-BCP cohort), (n=29 and 53, respectively).
Conclusions
Preliminary analyses suggest patients managed within a BCP have their biologic management guided more often by the results of TDM and objective biomarkers than those not managed within a BCP. Although clinical remission was observed to be similar between the cohorts, attainment of endoscopic remission was more likely amongst patients managed within the BCP. Additional multivariate analyses will be presented at CDDW with a larger cohort size.

Abstract
Abstract
Background
Inflammatory Bowel Disease (IBD) is a chronic, immune-mediated disease, with Canada demonstrating the highest incidence and prevalence rates in the world. Patients with IBD often require lifelong treatment and, therefore, lifelong interactions with the healthcare system. Access to care can have a direct impact on patient health-related outcomes. Although acknowledged as a problem, the complexity of accessing IBD specialty care in Canada has not been reviewed. This lack of understanding presents a barrier in evaluating and implementing changes in IBD specialty care.
Aims
To identify key barriers and facilitators for and to develop a national working strategy to address limitations in access to IBD specialty care by exploring the perceptions and experiences of key stakeholders (pediatric and adult gastroenterologists, IBD patients, researchers, and policy makers).
Methods
The IBD Summit was held in Toronto, Ontario in November 2017, sponsored by SPOR-CIHR catalyst funding and in partnership with Crohn’s & Colitis Canada. Perceptions and experiences of key stakeholders were gathered during two audio-recorded stakeholder dialogues held during the Summit. The audio recordings were transcribed and coded to compare and contrast between key stakeholders to determine potential differences in access to IBD care. Five final themes are highlighted in this report.
Results
A total of 21 key stakeholders attended, including pediatric and adult gastroenterologists, patients, researchers, and policy makers. Five key themes of importance relating to access to IBD care arose from The IBD Summit:(1) Integrated Models of Care, (2) IT Enhanced Care, (3) Health System Process, (4) Communication and Advocacy, and (5) Community Supports. The IBD Summit identified similar perceptions and experiences, highlighting common barriers and facilitators that transcend provincial borders. Shared perceptions included a need for common medical records and overall improved IT-enhanced care for managing IBD; improved centralized triage systems; increased comprehensive care support for patients and primary care physicians; and increased community supports for patients and providers.
Conclusions
Highlights from the IBD Summit present several clinically relevant and actionable suggestions for improved access to IBD speciality care across Canada. The suggestions provided by key stakeholders highlight the need for a system-level redesign in order to improve access to enhanced models of care. Improvements in access to IBD specialty care can only occur through partnerships between those working within the healthcare system and those within the community. Future research will involve pursuing deeper insight into the experience of patient and provider stakeholders as they navigate the healthcare system in order to access and provide care.

Abstract
Abstract
Background
Most administrative studies of hospitalization in inflammatory bowel disease (IBD) use two definitions: IBD in any diagnostic position (IBD-ANY), and IBD as the most responsible diagnostic (IBD-MRD). There is a third less commonly used definition: total hospitalization; this definition captures all hospitalizations of prevalent IBD patients and therefore it can give a more realistic picture of the burden of IBD.
Aims
To compare differing definitions (total, IBD-ANY, and IBD-MRD) of hospitalizations.
Methods
A previously defined population-based IBD prevalent cohort for Alberta (n=30,698) was used to pull all hospital admissions from the Discharge Administrative Database (DAD; 2002–2015). Three hospitalization definitions were used: i. Total (all hospitalizations of prevalent cohort independent of presence of code for IBD); ii. IBD-ANY (code for IBD [K50.x; K51.x] contained in any diagnosis field); and, iii. IBD-MRD (most responsible diagnosis was IBD). Age- and sex- standardized rates (2015 Canadian population) were calculated using the prevalent population. Log-linear regression was performed to calculate Average Annual Percentage Change (AAPC) with associated 95% confidence intervals (CI) of each type of hospitalization. We assessed the top five most common most-responsible diagnosis codes for hospitalizations that were contained in the total hospitalizations but not an IBD-ANY hospitalization.
Results
From 2002 to 2015, 63.5% of IBD prevalent patients in AB had ≥1 hospitalization; 44.2% had ≥1 IBD-ANY hospitalization; 28.6% had ≥1 IBD-MRD hospitalization; and, 40.6% had a hospitalization that did not contain a code for IBD. All hospitalization rates decreased significantly over time. Of the top five most common most responsible diagnosis, contained in admissions that were not IBD-ANY, three were gastroenterological: i. K52.9 (non-infective gastroenteritis); ii. A09.9 (diarrhea and gastroenteritis of presumed infectious origin); and, iii. Z43.2 (attention to ileostomy).
Conclusions
Total hospitalizations is an important measure to report since accounting for all hospitalizations of IBD patients is necessary in order to allocate healthcare resources appropriately. To be able to ensure these patients receive the care they need we need to be able to accurately assess the true burden of IBD.

Abstract
Forty-two individuals from the Gaza Strip were typed by Next Generation Sequencing (NGS) for HLA-A, -B, -C and -DRB1. Haplotypes were established by descent and only one haplotype was found to occur more than once; HLA-A*23:01 ~ B*41:01 ~ DRB1*07:01. The allele and haplotype frequencies and the individual genotypes are deposited at www.allelefrequencies.net (AFND) under population name Gaza and population ID number 3664 Dos Santos et al. (2016) [1].
