Abstract
OBJECTIVES Chronically ill adolescent and young adult (AYA) patients experience barriers to accessing psychosocial care. AYAs who receive palliative and psychosocial care experience numerous benefits from these services. However, we still lack research investigating age-appropriate programs targeting AYAs' psychosocial needs that are delivered virtually and extend beyond the hospital setting. Streetlight is a palliative care program designed for chronically ill AYAs that offers the Streetlight Gaming League (SGL), an online health community (OHC) combining peer-based support, online gaming, and community events. We evaluated the usefulness, acceptability, and potential effectiveness of SGL through an assessment of chronically ill AYAs' lived experiences. METHODS We used a qualitative evaluation approach grounded in hermeneutic phenomenology. Questionnaires and interviews were conducted with 9 chronically ill AYAs to elicit in-depth accounts of their lived experiences of using SGL. Descriptive statistical analysis was performed on questionnaire data. Phenomenological data analysis, informed by hermeneutic analysis, was used to analyze interviews. RESULTS AYAs reported positive experiences with SGL and valued the ability to engage in various content while having few participation expectations. They also described psychosocial benefits, including reprieve from illness, sense of community, and solidarity through mutual understandings and shared experiences. SIGNIFICANCE OF THE RESULTS Findings highlight the usefulness and acceptability of a virtual palliative psychosocial care program for chronically ill AYAs. Findings also suggest the effectiveness of SGL and support using an OHC to meet the psychosocial needs of AYAs. This study can guide future programming and implementation of online palliative psychosocial care programs in other hospital settings, resulting in similar beneficial and meaningful experiences.

A randomized trial of retropubic vs single-incision sling among patients undergoing vaginal prolapse repair. Am J Obstet Gynecol 2024:S0002-9378(24)00562-3. [PMID: 38705225 DOI: 10.1016/j.ajog.2024.04.036] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2024] [Revised: 03/27/2024] [Accepted: 04/22/2024] [Indexed: 05/07/2024]
Abstract
BACKGROUND The choice of midurethral sling type may impact efficacy and complications in women undergoing transvaginal native tissue repair of pelvic organ prolapse. OBJECTIVE The primary aim was to determine if the single-incision sling is noninferior to retropubic sling for the management of stress urinary incontinence among patients undergoing reconstructive or obliterative native tissue vaginal repair. The secondary aims were to compare adverse events and surgeon ease of use with sling assignment. STUDY DESIGN A multicenter, noninferiority, randomized trial of women with ≥ stage II pelvic organ prolapse and objectively confirmed stress urinary incontinence undergoing reconstructive or obliterative vaginal repair was performed. Women were randomized to concomitant single-incision (Altis sling, Coloplast Minneapolis, MN) with suprapubic sham incisions or retropubic slings. The primary dichotomous outcome was abnormal lower urinary tract function within 12 months postsurgery, defined as bothersome stress urinary incontinence symptoms (>1 Pelvic Floor Distress Inventory question no. 17); retreatment for stress urinary incontinence or treatment for urinary retention. Secondary outcomes were adverse events, Patient Global Impression of Improvement of bladder function, and surgeon ease of use (1, worst; 10, best). All subjects completed validated questionnaires and underwent a Pelvic Organ Prolapse Quantification, cough stress test, and postvoid residual preoperatively, at 6 weeks and 12 months postoperatively. Assuming a subjective cure rate for retropubic of 82%, 80% power, and 1-sided 5% significance level, we estimated that 127 patients in each arm were needed to declare noninferiority of the single-incision sling if the upper bound of the 95% confidence interval for the between-group difference per protocol in abnormal bladder function was <12%. Assuming a 10% loss to follow-up, the total enrollment goal was 280. RESULTS Between December 2018 and January 2023, 280 subjects were enrolled across 7 sites, and 255 were randomized: 126 were for single-incision, and 129 were for retropubic sling. There were no preoperative or operative characteristic differences between groups. Overall, 81% had reconstructive, and 19% had obliterative native tissue repairs. The primary outcome, abnormal lower urinary tract function at 12 months, occurred in 29 (25%) of single-incision vs 24 (20%) of the retropubic sling group (risk difference, 0.04472 [95% confidence interval, -0.03 to 0.1133]; P=.001 for noninferiority). Bothersome stress urinary incontinence occurred in 20% vs 17% (P=.27) and was retreated in 4% vs 2% (P=.44) of single-incision vs retropubic groups, respectively. Adverse events were reported in 24 (16%) of single-incision vs 14 (9%) of the retropubic group (95% confidence interval, 0.95-3.29; P=.70) and included de novo or worsening urgency incontinence symptoms, urinary tract infection, mesh exposure, need for prolonged catheter drainage, and de novo pain, without differences between groups. Patient Global Impression of Improvement (very satisfied and satisfied) was 71% vs 67% (P=.43), and median surgeon ease of sling use was 8 (7-10) vs 9 (8-10), P=.03 in single-incision vs retropubic, respectively. CONCLUSION For women undergoing vaginal repair, single-incision was noninferior to retropubic sling for stress urinary incontinence symptoms, and complications, including treatment for urinary retention, did not differ.

Abstract
IMPORTANCE Robot-assisted sacrocolpopexy (SCP) is a commonly performed procedure for the repair of apical pelvic organ prolapse; therefore, novel devices and techniques to improve safety and efficacy of this procedure should be explored. OBJECTIVE The objective of this study was to assess safety and efficacy of 8-mm trocar site for use of a disposable suture/needle management device (StitchKit; Origami Surgical, Madison, NJ) for robot-assisted SCP with a 4-arm configuration and no assistant port. STUDY DESIGN This is a retrospective case series of patients undergoing robot-assisted SCP at a tertiary center from 2018 to 2021. All surgical procedures were performed using four 8-mm robotic trocars and StitchKit device. Our objective was to review all cases in which this technique was used to determine whether the approach resulted in a safely completed procedure and any complications or adverse events. Secondary objectives were to describe patient and operative characteristics. RESULTS In total, 422 patients underwent robot-assisted SCP for pelvic organ prolapse. The mean age was 60 ± 10 years, and mean body mass index was 27 ± 6 (calculated as weight in kilograms divided by height in meters squared). Most patients had stage 3 prolapse (73%) and underwent concomitant hysterectomy (70%). Ninety-nine percent (n = 416) of cases were completed robotically. StitchKit was successfully inserted and removed in all robotic cases with correct needle counts. All patients had postoperative visits, and 80% followed up at 3 months. No umbilical/port site hernias, operative site infections, or adverse events were reported. CONCLUSIONS Robot-assisted SCP can be performed safely using a 4-arm robotic configuration and suture kit device. This setup eliminates incisions greater than 8 mm and an assistant port, allowing for surgical efficiency without compromising patient outcomes.

Abstract
IMPORTANCE Routine screening for urinary incontinence (UI) by primary care providers (PCPs) is recommended. OBJECTIVES We aimed to describe the rate of incident UI diagnosed at annual PCP visits, the prevalence of UI in a large primary care population, and estimate the rate of screening for UI during primary care preventive and annual wellness visits. Secondary aims were to describe PCP knowledge and behavior as they relate to UI screening and diagnosis. STUDY DESIGN The electronic health record was used to abstract the number of adult female patients seen by PCPs within a regional health system with a diagnosis of UI before our study period and with a new diagnosis over a 2-year period. Additional new diagnoses and screening practices were found on chart review of an additional 824 representative charts. Primary care providers within the health system were surveyed about their screening practices and knowledge about UI. RESULTS There were 192,053 women primary care patients seen over 2 years. A total of 5.7% had a UI diagnosis preceding the study period and 3.4% had a UI diagnosis during the study period. A total of 42% of PCPs reported that they screen for UI at least half the time and none were completely satisfied with their ability to screen for UI. Sixteen percent of annual wellness visits had any documentation of screening for UI. CONCLUSION In a large primary care population, screening for and detection of UI in women was low.

Abstract
BACKGROUND Nutritional status is paramount in Cystic Fibrosis (CF) and is directly correlated with morbidity and mortality. The first ESPEN-ESPGHAN-ECFS guidelines on nutrition care for infants, children, and adults with CF were published in 2016. An update to these guidelines is presented. METHODS The study was developed by an international multidisciplinary working group in accordance with officially accepted standards. Literature since 2016 was reviewed, PICO questions were discussed and the GRADE system was utilized. Statements were discussed and submitted for on-line voting by the Working Group and by all ESPEN members. RESULTS The Working Group updated the nutritional guidelines including assessment and management at all ages. Supplementation of vitamins and pancreatic enzymes remains largely the same. There are expanded chapters on pregnancy, CF-related liver disease, and CF-related diabetes, bone disease, nutritional and mineral supplements, and probiotics. There are new chapters on nutrition with highly effective modulator therapies and nutrition after organ transplantation.

Abstract
PURPOSE Peer-assisted learning (PAL) can occur informally as part of a medical programme and complements the formal curriculum. However, little is known about the mechanisms and processes of how informal peer-assisted learning (IPAL) is enacted. MATERIALS AND METHODS This paper presents data from an ethnographic and semi-structured interview study with Year 1 and 2 undergraduate medical students at a UK university. RESULTS Peers were observed assisting each other informally: a process that developed as part of the integrated, group-based approach to undergraduate medical education at a UK university. IPAL took place both within and outside of formal teaching sessions and included explanation/clarification of particular points, sharing resources, guiding pronunciation and demonstrating skills. Students placed a high value on IPAL and believed that it was beneficial. When IPAL broke down, this led to negative emotions that presented obstacles to learning, such as resentment. CONCLUSIONS IPAL is an important part of academic support for medical students, and this work shows both its scope, extending from formal to informal teaching, and how it is enacted. This understanding can help educators situate IPAL within student education.

Abstract
PURPOSE Strategies for preventing and ending homelessness are frequently measured by their effectiveness on indices of tenancy sustainment. To shift this narrative, we conducted research to identify what is needed to "thrive" following homelessness from the perspectives of persons with lived experience in Ontario, Canada. METHODS Conducted in the context of a community-based participatory research study aimed at informing the development of intervention strategies, we interviewed 46 persons living with mental illness and/or substance use disorder [n = 25 (54.3%) unhoused; n = 21 (45.7%) housed following homelessness] using qualitative interviews. A subsample of 14 participants agreed to engage in photovoice interviews. We analysed these data abductively using thematic analysis informed by health equity and social justice. RESULTS Participants described experiences of "living in a state of lack" following homelessness. This essence was expressed through four themes: 1) housing as part one of the journey to home; 2) finding and keeping "my people"; 3) meaningful activity as critical for thriving following homelessness; and 4) struggling to access mental health supports in the context of challenging circumstances. CONCLUSIONS Individuals struggle to thrive following homelessness in the context of insufficient resources. There is a need to build on existing interventions to address outcomes beyond tenancy sustainment.

Abstract
The DNA damage response is essential to safeguard genome integrity. Although the contribution of chromatin in DNA repair has been investigated1,2, the contribution of chromosome folding to these processes remains unclear3. Here we report that, after the production of double-stranded breaks (DSBs) in mammalian cells, ATM drives the formation of a new chromatin compartment (D compartment) through the clustering of damaged topologically associating domains, decorated with γH2AX and 53BP1. This compartment forms by a mechanism that is consistent with polymer-polymer phase separation rather than liquid-liquid phase separation. The D compartment arises mostly in G1 phase, is independent of cohesin and is enhanced after pharmacological inhibition of DNA-dependent protein kinase (DNA-PK) or R-loop accumulation. Importantly, R-loop-enriched DNA-damage-responsive genes physically localize to the D compartment, and this contributes to their optimal activation, providing a function for DSB clustering in the DNA damage response. However, DSB-induced chromosome reorganization comes at the expense of an increased rate of translocations, also observed in cancer genomes. Overall, we characterize how DSB-induced compartmentalization orchestrates the DNA damage response and highlight the critical impact of chromosome architecture in genomic instability.

Abstract
BACKGROUND Cystic fibrosis diabetes (CFD) is a very common co-morbidity affecting the lives of people with cystic fibrosis. Surprisingly, minimal research has been undertaken to understand the experiences of people with CFD and how they self-mange this condition. METHODS Using interpretative phenomenological analysis, the present study examined the self-management experiences of people with CFD. In-depth semi-structure interviews were conducted with eight people who had CFD. RESULTS The following three superordinate themes were identified: forming a relationship with CFD, balancing the CFD self-management triad, and the unmet need for information and support. CONCLUSIONS The findings suggest that the management of CFD is challenging and, although people with CFD experience many adaptation and management processes similar to people with type 1 diabetes, they struggle with the additional complexity of balancing CF and CFD. The provision of appropriate education, support and person-centred care needs to be addressed.

Abstract
There is increasing interest in the African spiny mouse (Acomys cahirinus) as a model organism because of its ability for regeneration of tissue after injury in skin, muscle, and internal organs such as the kidneys. A high-quality reference genome is needed to better understand these regenerative properties at the molecular level. Here, we present an improved reference genome for A. cahirinus generated from long Nanopore sequencing reads. We confirm the quality of our annotations using RNA sequencing data from 4 different tissues. Our genome is of higher contiguity and quality than previously reported genomes from this species and will facilitate ongoing efforts to better understand the regenerative properties of this organism.

Abstract
IMPORTANCE Decision analysis tools (DAT) are shared decision making instruments that include patient input on treatment goals and values that have been shown to decrease decisional regret in women's health care. OBJECTIVE We describe a novel, computerized DAT for patients with urinary incontinence (UI), and our primary aim was to assess the concordance between treatment fit as determined by the DAT and treatment selected after physician counseling in patients with urgency urinary incontinence and urgency predominant mixed urinary incontinence. STUDY DESIGN We partnered with a health care startup to develop a computerized DAT incorporating evidence about UI and patient input about treatment goals and personal values. This is a retrospective cohort study examining the concordance of DAT-predicted treatments identified before consultation with the physician and those chosen after counseling. Electronic medical records were reviewed to abstract demographic, clinical data, and treatments chosen at the initial physician consultation. Because it was possible to pursue concurrent treatment options (ie, pelvic floor physical therapy and medications), the first 2 modalities identified in the treatment plan at consultation were abstracted. Descriptive statistics were conducted using SPSS®, we did not adjust for multiple comparisons. RESULTS Four hundred eighty-nine patients met the inclusion criteria for our study, and 65% of the cohort chose treatment options after counseling that were concordant with their DAT best treatment fit. CONCLUSION Patients choosing treatment for urgency urinary incontinence and urgency predominant mixed urinary incontinence using a novel, computer-based DAT to prepare for shared decision making with their physicians often choose to proceed with their top DAT-determined treatment fit after counseling.

Abstract
Objective.Optical computed tomography (CT) is one of the leading modalities for imaging gel dosimeters used in the verification of complex radiotherapy treatments. In previous work, a novel fan-beam optical CT scanner design was proposed that could significantly reduce the volume of the refractive index baths that are commonly found in optical CT systems. Here, the proposed scanner has been manufactured and commissioned.Approach.Image reconstruction is performed through algebraic reconstruction technique and iterated using the fast iterative shrinkage-thresholding algorithm (FISTA) algorithm. Ray tracing for algebraic reconstruction was performed using an in-house developed ray tracing simulator. A set of Sylgard® 184 phantoms were created to commission spatial resolution, geometric deformity, contrast-to-noise ratio (CNR), and scan settings.Main Results.The scanner is capable of a 0.929 mm-1spatial resolution, observed at 200 iterations, although the spatial resolution is highly dependent on the number of iterations. The geometric distortion, measured by scanning a needle phantom with the prototype scanner as well as a conventional x-ray CT was found to be within <0.25 mm. The CNR was found to peak between 65 and 190 occurring between 50 and 100 iterations and was highly dependent on the region chosen for background noise calculation. The proposed scanner is capable of scanning and reading out slices in less than 1 min per slice.Significance.This work displays the viability of a fan-beam optical CT scanner with minimal index matching using ray-traced algebraic reconstruction.

Abstract
Background Chronic gut dysfunction occurs in up to 25% of patients following antibiotic-treated C. difficile infection (CDI). We developed a humanized mouse model in which germ free mice colonized with microbiota from patients with severe constipation post-CDI developed slow colonic transit, as a result of damage to the Interstitial Cells of Cajal (ICC) network by pro-inflammatory macrophages. Colonic transit, immune activation and the ICC network normalized after fecal microbiota transplantation using samples from healthy mice, as well after treatment with psyllium fiber. Here we explored the long-term effects of psyllium and evaluated the therapeutic potential of pectin and quercetin in this model. Purpose 1) To investigate the time course of the beneficial effect of psyllium on colonic motility. 2) To explore possible therapeutic properties of flavonoids and pectin. Method Germ-free mice were colonized with microbiota from the post-CDI (PCDI) patient or healthy controls (HC). After 3 weeks, the mice were fed for 4-5 weeks with a control diet or diets with 15% psyllium (PSY), 10% pectin (PCT) or 0.05% quercetin (QCT). To evaluate time course of PSY on motility, control diet was administered for 3-weeks following PSY treatment. The bead expulsion test was used to assess colonic motility. Stool samples were collected for microbial profiling, and short and branched-chain fatty acids (SCFA/BCFA) analysis. Macrophages morphology and counts, and ICC network structure were evaluated by immunohistochemistry. Result(s) Compared to HC microbiota, colonization with post-CDI microbiota induced slow colonic transit in recipient mice, and this was normalized by PSY (n=13; p=0.02). The benefit of PSY was transient as colonic transit slowed following discontinuation of PSY (p=0.001). The changes in colonic transit were paralleled by switch in macrophages phenotype and damage to the ICC network. Additionally, discontinuation of PSY resulted in a return of microbial diversity (p< 0.001), SCFA/BCFA levels (acetic and propionic acid/ iso-butyric and valeric acid) and specific bacterial species abundances, to values seen in untreated mice colonized with post-CDI microbiota. Microbial analysis predicted potential pathways involved in macrophage polarization, including the synthesis of SCFA/BCFA, degradation of inositol and production of acetylglucosamine. PCT also normalized slow intestinal transit in mice colonized with post-CDI microbiota (p=0.003), restored phenotype of infiltrating macrophages, and improved the structural integrity of the ICC network. In contrast, QCT failed to improve gut dysfunction in PCDI mice. Conclusion(s) Our results suggest that the beneficial effects of psyllium in this model are transient. Dietary pectin, but not quercetin, may also serve as a novel treatment strategy to restore colonic motility and immune homeostasis in humans with severe constipation post-CDI.

Abstract
Background The circadian clock is a self-sustained molecular oscillator which drives 24-hour physiological rhythms. It consists of the genes Bmal1 and Clock that positively regulate Cry and Per, their negative regulators, resulting in a 24-hour transcription/translation feedback loop. Shift work, which causes disruptions to 24-hour physiological rhythms, has been shown to lead to an increased incidence of inflammatory bowel disease (IBD). We have previously established that mice lacking the non-redundant circadian regulator, Bmal1, exhibit more severe colitis compared to controls. Purpose This study aims to investigate the epithelial function of Bmal1 in colonic regeneration during colitis. Method In order to assess the cell-specific role of the clock, we tested the regenerative effects of Bmal1 in intestinal epithelial tissue using Vil+/+;Bmal1flox/flox (control) and VilCre/+;Bmal1flox/flox (conditional mutant) mice. Dextran Sulfate Sodium (DSS) was applied to induce acute colitis. Disease progression was evaluated during colitis and during recovery upon removal of DSS treatment. We hypothesized that the absence of a functional circadian clock disrupts effective proliferation and regeneration of intestinal epithelial cells during colitis remission. Result(s) Vil+/+;Bmal1flox/flox control and VilCre/+;Bmal1flox/flox conditional mutant mice exhibit no significant differences in disease severity or tissue histopathology during colitis. However, after the removal of DSS, VilCre/+;Bmal1flox/flox conditional mutants show increased total lesions and overall inflammation, decreased crypt density as well as a higher propensity of hyperplastic crypts in the tissue. Regenerative ability of the colon is decreased in conditional mutants: phosphorylated-histone H3 and Ki67 show persistent increases in mitosis and overall proliferation near ulcerated lesions. This suggests that, while controls complete the regenerative response, conditional mutants fail to recover from colitis and show inefficient regeneration when Bmal1 is disrupted in intestinal epithelial cells. Conclusion(s) Our results support a critical role for Bmal1 in intestinal epithelial cells during post-colitis regeneration and recovery.

Abstract
Background Although intestinal muscle layer macrophages have been suggested to play an important role in the colonic transit by interacting with the myenteric plexus neurons, they have not been fully characterized. CD64 (FcγRI) is one of the most generally used markers for intestinal macrophages, but several studies suggested existence of a subpopulation of macrophages that lack CD64. In addition, the muscle layer macrophage subsets currently identified are considered to be same in the small intestine and colon, although this has not been formally tested. Purpose In this study, we aim to identify and characterize the subsets of muscle layer macrophages by CD64 marker. We hypothesize that colon specific CD64-macrophages have a different role from CD64+ conventional macrophages. Method The muscle layers of small intestine (ileum) and colon were separated from SPF mice and cells from each muscle layer were analyzed by flow cytometry and fluorescent staining. The muscle layer macrophages were gated withCD45+, F4/80+, CD11b+ and Ly6c-, and analyzed with CD64 and MHCⅡmarkers by flow cytometry. In additional experiments, fluorescent staining with CD64 and F4/80 was assessed in whole-mount tissue of the separated muscle layer. Result(s) Within the macrophage population from the colon muscle layer, we found not only CD64+ cells, a conventional marker of macrophage, but also CD64- cell population (CD45+, F4/80+, CD11b+, Ly6c-). However, in the small intestine, this CD64- cell population was barely detectable. In addition, colonic CD64+ cells had mostly high expression of MHCⅡ marker, while CD64- cells had low expression of MHCⅡ. A similar pattern was found when we examined intestinal and colonic tissues by immunofluorescent staining. Conclusion(s) We identified a colon-specific CD64- subset of macrophage in muscle layer. Additional experiments are needed to characterize their immunomodulatory properties.

Abstract
Background Generalized anxiety disorder (GAD) is a debilitating condition with a lifetime prevalence of 4-7% worldwide. We have previously found that compared to healthy controls, GAD patients had lower reported fiber intake, increased gastrointestinal symptoms; and enrichment of Bacteroides genus as well as carbohydrate metabolism pathways (as determined by PICRUSt2, correlated to Bacteroides abundance). Bacteroides are known for its ability to degrade a wide variety of host polysaccharides, such as the intestinal mucus, which could lead to local and systemic inflammation. In this regard, GAD patients had higher C-reactive protein (CRP) compared to healthy controls (p=0.049). Purpose To investigate whether a fiber-free diet could decrease Bacteroides abundance and prevent damage of the mucus layer reducing anxiety-behavior in mice with GAD microbiota. Method Two germ-free NIH Swiss mouse breeding pairs were colonized with GAD microbiota using patients’ stool samples and kept on either fiber-free or 10 % inulin (fiber) diet. Offspring were weaned at week 3 and psychometric tests were performed at 10 weeks of age. After sacrifice, samples for histology (mucus layer thickness determination), blood (CRP ELISA determination) and stool (Illumina 16S rRNA gene sequencing) were collected. The microbiota data was analyzed following the pipelines of dada2 and by mean comparisons, correlation, AncomBC using R software (v.1.2.1335). Multiple comparison results were corrected allowing 5% of FDR. Result(s) Beta diversity analysis showed that parent and offspring’s (n=24 fiber-supplemented and n=14 fiber-free groups) microbiota was similar to the GAD donor. The most differentially abundant bacterial taxon was Bacteroides uniformis, which was decreased in the fiber-free group (p.adj= 0.003). Furthermore, fiber-free diet reduced the overall Bacteroides abundance by half compared to the donor and fiber-supplemented mice group. This led to a thickening (p.adj=0.027) of the mucus layer, increasing from 30 µm (fiber-supplemented diet) to 60 µm in the fiber-free diet group. B. uniformis was negatively correlated to the mucus layer thickness (R= -0.81; p.adj=0.26), although not statistically significant, likely due to a low n number (n=4). We only found a statistical trend for higher CRP levels and anxiety-like behavior in the fiber-supplemented group. This might be because fiber supplementation has several beneficial effects that can counteract the proposed increase in anxiety-like behavior fromBacteroides. Despite that, we found a significant correlation between B. uniformis and time mice spent in the dark (indicative of anxiety-like behavior) in the light preference test. Conclusion(s) Our data suggests that Bacteroides abundance, specifically Bacteroides uniformis, contributes to the degradation of the mucus layer and potentially triggers low grade gut inflammation and anxiety-like behavior.

Abstract
Background Patients with irritable bowel syndrome (IBS) often report gastrointestinal symptoms after consuming wheat and gluten-containing foods. It is, however, unclear whether gluten is the main driver of symptoms, as other immunogenic peptides, such as amylase trypsin inhibitors (ATI), poorly digestible fiber (inulin, part of FODMAP) or even the nocebo effect may contribute to symptom generation. Purpose To evaluate whether whole wheat containing ATIs and/or purified gluten trigger gastrointestinal symptoms compared to nocebo in patients with IBS adopting a gluten-free diet (GFD). Method We conducted a double-blind, randomized, nocebo-controlled crossover study in adult IBS patients (Rome IV criteria) who previously perceived improvement of symptoms while on a GFD. The study was approved by the Hamilton Research Ethics Board (HiREB #4367). Participants were challenged for 7 days with whole wheat, purified gluten, and nocebo (gluten-free flour) added to low FODMAP cereal bars. Each challenge was followed by a 2-week washout. Patients remained on a GFD throughout the study, diet adherence was assessed by a dietitian and stool gluten immunogenic peptides (GIP; Biomedal). Gastrointestinal symptoms were assessed by IBS Symptom Severity Score (IBS-SSS); increases >50 points were considered a significant worsening. Blood samples were collected to assess immune markers and celiac (HLA DQ2, DQ8 and DQ7) genotype. Statistical comparisons used Friedman rank sum tests and paired Wilcoxon signed rank tests. Result(s) Twenty-nine IBS patients (27 female, mean age=42, SD=14.4 years) were enrolled in the study; 1 dropped. Similar proportions of patients reacted symptomatically to wheat (11/28, 39.3%), gluten (10/28, 35.7%) and nocebo (8/28, 28.6%). However, there was an overall significant increase in IBS symptoms after wheat (+39.5 on IBS-SSS; p=0.030) but not after gluten (+27.5; p=0.051) or nocebo (+5.5; p=0.236) challenges (Figure 1). Ten participants experienced IBS-SSS symptoms >175 during baseline and did not worsen further during the challenges. TNF-α trended from 1.35 pg/mL after nocebo, 1.47 pg/mL after gluten, to 1.57 pg/mL after wheat; however, this was not significant. Baseline adherence to a GFD was rated excellent in 19 (68%), good in 6 (21%), and fair in 3 (11%) participants. Median GIP levels were 0.584 µg/g after wheat, 0.432 µg/g after gluten, and 0.095 µg/g after nocebo; p<0.0001. Celiac predisposition genes were present in 19/24 participants (10/24 had DQ2, 2/24 had DQ8, and 9/24 had DQ7). Image ![]()
Conclusion(s) IBS patients self-reporting wheat or gluten sensitivity had worse symptoms after whole wheat, but not purified gluten or nocebo challenge. However, similar proportions of IBS patients reacted to each intervention, suggesting that central mechanisms play an important role in symptom genesis. Furthermore, one third of patients had high symptoms during a GFD and did not react to wheat or gluten challenges, suggesting that other mechanisms are driving their IBS symptoms.

A265 TEMPORAL DYNAMICS OF SYMPTOMS AND GUT MICROBIOTA IN EPISODES OF IRRITABLE BOWEL SYNDROME. J Can Assoc Gastroenterol 2023.

Abstract
Background Irritable bowel syndrome (IBS) is a disorder of gut-brain axis that manifests with chronic abdominal pain, altered bowel habits, and frequent psychiatric comorbidities. Despite mounting evidence showing gut microbiota composition and associated metabolites being altered in IBS, the mechanisms by which they drive the symptoms are unclear. We have previously shown that several IBS symptoms co-occur, that their severity vary among IBS subtypes (10.1093/jcag/gwab049.050), and that several bacterial taxa are differentially modulated during periods of symptom flares and remission. Here we investigate whether the changes in gut microbiome and bacterial metabolites are linked to symptom occurrence and severity. Purpose To investigate temporal associations of IBS symptoms with gut microbiota profiles and metabolites. Method 16S rRNA gene sequencing was performed on stool samples of 28 IBS patients (IBS-D n=20, IBS-C n=8) and 10 healthy controls (HC), collected weekly over a period of 25 weeks, during which gut and mood symptoms were recorded (total of 950 samples). Correlations between principal ordinates obtained from symptom scores and microbiota beta diversity were studied using Procrustes analysis in R. Metabolomics was performed by Mass Spectrometry and analysed using MetaboAnalyst 5.0. Statistical significance was set at p<0.05. Result(s) Significant correlation was found between the symptom scores and microbiota beta diversity ordinates over time in 7 patients (5 IBS-D and 2 IBS-C subjects) out of 28 IBS patients. Metabolomics performed on samples selected based on Procrustes analysis and symptom severity scores of individual subjects showed that several pathways are altered in IBS patients (both subtypes) compared to HC, including primary bile acid biosynthesis, beta alanine metabolism, pyrimidine and histidine metabolism. Furthermore, during symptom flares, ornithine, citrulline and gluconic acid vary in IBS-D, while amino acids cysteine, methionine, threonine, and glycine vary in IBS-C subjects. Conclusion(s) Our results suggest that IBS symptoms and changes in gut microbiota composition and metabolites must be studied in conjunction, in order to understand the mechanisms underlying IBS pathophysiology. We found that same pathways are altered in IBS subjects irrespective of their subtype, suggestive of a basal metabolic shift in IBS patients. This shift may make them sensitive to further gut microbial modulation of carbohydrate and protein metabolism in IBS-D and IBS-C subjects, respectively, leading to symptom flares. Further analyses are needed to investigate these metabolites and associated bacteria, as they can help identifying subsets of patients with specific disease mechanisms. This will be a steppingstone in moving away from symptom-based subtyping towards mechanism-based grouping and developing effective treatment strategies accordingly.

Abstract
Abstract
Background
Chronic abdominal pain is the most common complaint of patients with gastrointestinal disorders. Its treatment is of limited efficacy as the pathophysiology is poorly understood. The gut microbiome has been shown to affect host physiology, including the neural system function, and growing evidence suggests that it plays an important role in pain perception. Gut microbiota produces a large variety of molecules that can regulate pain perception, such as histamine or bioactive lipids. Phospholipid mediators (PLM) are signaling molecules linked to neurogenic pain as by-products of inflammatory processes in mammals. But it is unknown whether bacteria can produce PLM and whether they play any role in visceral hyperalgesia.
Purpose
To investigate whether PLM are present in stool of patients with chronic abdominal pain, and whether they have potential to induce visceral hypersensitivity.
Method
Stool samples from 27 patients with irritable bowel syndrome (IBS) were collected both during periods of severe and minimal/no pain. The fecal concentration of two PLM (lipid A and lipid B) was determined by ELISA. The passage of lipid A and lipid B through the intestinal barrier was determined ex vivo using Ussing chambers and in vivo by their intracolonic instillation, and their levels assessed in the serosal compartment and the serum, respectively, by ELISA. We used primary cultures of sensory neurons from the dorsal root ganglia (DRG) of conventional mice (SPF) to study the neuronal activation in vitro. Calcium mobilization in DRG sensory neurons was measured by an inverted fluorescence microscope using a fluorescent probe Fluo-4 (1mM) after stimulation with different concentration of lipid A or lipid B. Visceral sensitivity in vivo after intracolonic instillation of combined lipids A and B was evaluated by colorectal distension.
Result(s)
The concentration of lipid A (p=0.001) and lipid B (p=0.002) in stool was significantly higher in IBS patients when experiencing severe abdominal pain compared to periods of minimal pain. The concentration of lipid A (p=0.03; p=0.07) and lipid B (p=0.018; p=0.018) in the serosal compartment and in the serum, respectively, was higher compared to the control condition. The percentage of neurons responding to lipid A or lipid B was significantly higher compared to the control condition, at all tested concentrations. Finally, combined lipid A and lipid B induced visceral hypersensitivity within 10 minutes (p=0.0433) and 90 minutes (p=0.0020) after intracolonic instillation.
Conclusion(s)
Our data suggest that PLM can be found in stool of patients with abdominal pain, that they cross the colonic barrier and increase visceral sensitivity. Further studies are needed to ascertain whether gut bacteria produce these PLM and investigate the precise mechanisms by which PLM induce hyperalgesia.

Do you see what I see? Testing horses' ability to recognise real-life objects from 2D computer projections. Anim Cogn 2023:10.1007/s10071-023-01761-6. [PMID: 36864246 PMCID: PMC9980859 DOI: 10.1007/s10071-023-01761-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2022] [Revised: 02/02/2023] [Accepted: 02/20/2023] [Indexed: 03/04/2023]
Abstract
The use of 2-dimensional representations (e.g. photographs or digital images) of real-life physical objects has been an important tool in studies of animal cognition. Horses are reported to recognise objects and individuals (conspecifics and humans) from printed photographs, but it is unclear whether image recognition is also true for digital images, e.g. computer projections. We expected that horses trained to discriminate between two real-life objects would show the same learnt response to digital images of these objects indicating that the images were perceived as objects, or representations of such. Riding-school horses (N = 27) learnt to touch one of two objects (target object counterbalanced between horses) to instantly receive a food reward. After discrimination learning (three consecutive sessions of 8/10 correct trials), horses were immediately tested with on-screen images of the objects over 10 image trials interspersed with five real object trials. At first image presentation, all but two horses spontaneously responded to the images with the learnt behaviour by contacting one of the two images, but the number of horses touching the correct image was not different from chance (14/27 horses, p > 0.05). Only one horse touched the correct image above chance level across 10 image trials (9/10 correct responses, p = 0.021). Our findings thus question whether horses recognise real-life objects from digital images. We discuss how methodological factors and individual differences (i.e. age, welfare state) might have influenced animals' response to the images, and the importance of validating the suitability of stimuli of this kind for cognitive studies in horses.

Abstract
Background:
Individuals experiencing homelessness have higher rates of cardiovascular disease than housed populations. Understanding cardiovascular health among unhoused individuals could inform health promoting programming and policies; however, this population is often difficult to reach and understudied.
Methods:
We partnered with Homeward—a regional coordinating agency for homelessness services—to assess cardiovascular health (CVH) via their semi-annual point-in-time (PIT) count. The PIT is a census of individuals experiencing homelessness in shelters and on the streets within the regional catchment on a pre-designated night. Trained staff administered a 10-minute electronic survey, which captured demographic information and cardiovascular health domains modeled after the American Heart Association’s “Life’s Essential 8”. Considering limited time and context, we used a pragmatic approach to define four behavioral health factors (sleep, food insecurity, physical activity, and smoking) and four self-reported health conditions (overweight/obesity, prediabetes/diabetes, high blood pressure, and high cholesterol). Each component earned 1 point for positive attributes (e.g., adequate sleep) or 0 for negative attributes (e.g., having high blood pressure). Components were summed to a score with a range of 0-8. We also assessed stress to create a broader measure ranging from 0-9 (with low stress earning an additional point). We performed a multivariable linear regression to understand correlates of cardiovascular health among individuals experiencing homelessness.
Results:
The PIT included 336 unhoused individuals currently sleeping in shelters or outdoors. The mean score for the 8-point measurement was 4.74 (SD=1.62), and the mean score for the 9-point measurement was 5.03 (SD=1.78). Neither the 8- nor 9-point score differed by gender, education, veteran status, length of homelessness, where the individual slept the night prior to the PIT count, or eviction history. In the adjusted model, increasing age was associated with a half point decrease in CVH score (β=-0.49; p =0.006). White unhoused respondents demonstrated a lower CVH score compared to Black respondents (β =-0.579; p =0.03) adjusting for other factors. Day laborers and part-time workers demonstrated approximately 1-point higher CVH scores (β =1.01; p=0.03; β =0.88; p=0.033, respectively) than unemployed individuals.
Conclusion:
Age, race, and employment status demonstrated associations with ideal cardiovascular health in this population of unhoused individuals in the southeastern US. Preliminary findings suggest that employment might be a target for cardiovascular health improvement among unhoused individuals.

Abstract
Background:
Black women demonstrate higher levels of stress over the life course compared to Black men, White men, and White women, which may help to explain their higher cardiovascular disease (CVD) morbidity and mortality. Despite implications for primary and secondary CVD prevention and racial disparities, few interventions have targeted psychosocial stress to improve blood pressure (BP) levels among Black women.
Objective:
To test whether a theory-driven, culturally tailored, community intervention focused on the stress experiences of Black women improves psychological outcomes and BP levels.
Methods:
The “Art for Hearts” pilot trial sought to examine the feasibility, acceptability, and preliminary efficacy of a novel intervention encouraging creative self-expression. This individual level, single-arm pilot trial recruited self-identified Black women ≥18 years. Women participated in an 8-week program, including 4 art sessions with a community artist (a self-identified Black woman) accompanied by a moderated focus group discussion and 4 heart health education sessions (facilitated by a Black woman researcher) on home BP monitoring, stress management techniques, diet/physical activity, and patient-clinician communication. All sessions were conducted in-person in a community space. Participants completed a survey including self-rated stress (scale of 0 to 7), perceived stress (PSS-10), depressive symptoms (PHQ-8), and anxiety symptoms (GAD-7) at baseline and 8 weeks. BP was measured by a trained assessor at baseline and 8 weeks as well as before and after each session. We examined within-participant changes in psychological measures as well as mean systolic and diastolic BP from baseline to 8 weeks.
Results:
The study included 18 Black women with a mean age of 44.1 (SD=15.4) years. Women were highly educated (36.8% with a graduate/professional degree) and 11.1% earned an income of ≥$100,000. Mean systolic BP was 114 mmHg and mean diastolic BP was 66 mmHg at baseline. From baseline to 8 weeks, self-rated stress level decreased by 1-point (from 4.36 to 3.18; p=0.005) (scale range: 0 -7). Perceived stress (-1.08; p=0.58) and anxiety (-1.33; p=0.09) decreased from baseline to 8 weeks; however, these changes did not achieve statistical significance. Depressive symptoms significantly improved from baseline to 8 weeks (19.13 to 13.38; p=0.044). There were no differences in systolic or diastolic BP from baseline to follow-up. The intervention was deemed feasible and acceptable with an attendance rate of >80%; participants expressed high overall satisfaction with the intervention.
Conclusion:
A tailored 8-week pilot intervention using painting self-expression demonstrated feasibility, acceptability, and preliminary efficacy for improving self-rated stress and depressive symptoms. No effects were demonstrated on BP in this sample.

Abstract
AIMS The European Society of Cardiology (ESC) EURObservational Research Programme (EORP) Non-ST-segment elevation myocardial infarction (NSTEMI) Registry aims to identify international patterns in NSTEMI management in clinical practice and outcomes against the 2015 ESC Guidelines for the management of acute coronary syndromes in patients presenting without ST-segment-elevation. METHODS AND RESULTS Consecutively hospitalised adult NSTEMI patients (n = 3620) were enrolled between 11 March 2019 and 6 March 2021, and individual patient data prospectively collected at 287 centres in 59 participating countries during a two-week enrolment period per centre. The registry collected data relating to baseline characteristics, major outcomes (in-hospital death, acute heart failure, cardiogenic shock, bleeding, stroke/transient ischaemic attack, and 30-day mortality) and guideline-recommended NSTEMI care interventions: electrocardiogram pre- or in-hospital, pre-hospitalization receipt of aspirin, echocardiography, coronary angiography, referral to cardiac rehabilitation, smoking cessation advice, dietary advice, and prescription on discharge of aspirin, P2Y12 inhibition, angiotensin converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB), beta-blocker, and statin. CONCLUSION The EORP NSTEMI Registry is an international, prospective registry of care and outcomes of patients treated for NSTEMI, which will provide unique insights into the contemporary management of hospitalised NSTEMI patients, compliance with ESC 2015 NSTEMI Guidelines, and identify potential barriers to optimal management of this common clinical presentation associated with significant morbidity and mortality.

Abstract
Background Improved survival rates for people with cystic fibrosis have led to increased rates of co-morbidity, of which diabetes is the most common. Cystic fibrosis related diabetes affects 19% of adolescents and up to 50% of adults, although little is known about their experiences of this co-morbidity. Aims To investigate the experiences of living with and managing cystic fibrosis related diabetes among adolescents and adults. Methods Systematic review and thematic analysis of qualitative evidence. Results Six studies, rated good quality, were included in the review and four main themes emerged from the data: knowledge and understanding; emotional and social impact; balancing both conditions; acceptance and adjustment. Although the main themes reflect adolescent and adult experiences, there were subtle variations in their sub-themes. Participants' overriding story was of journeying towards acceptance and integration of cystic fibrosis related diabetes into their lives. This included their unpreparedness for the likely onset of cystic fibrosis related diabetes and their struggles to balance the competing demands of living with and managing cystic fibrosis and diabetes. Conclusions The diagnosis of cystic fibrosis related diabetes and its incorporation into daily life is challenging for many people with cystic fibrosis. Review findings indicate opportunities for cystic fibrosis related diabetes interventions pre-diagnosis, at diagnosis, and during ongoing management, which need integrating into routine cystic fibrosis care.

PRACTICAL RELEVANCE The '2022 ISFM/AAFP Cat Friendly Veterinary Environment Guidelines' (hereafter the 'Cat Friendly Veterinary Environment Guidelines') describe how the veterinary clinic environment can be manipulated to minimise feline patient distress. Many components of a veterinary clinic visit or stay may result in negative experiences for cats. However, much can be done to improve a cat's experience by making the veterinary clinic more cat friendly. Exposure to other cats and other species can be reduced, and adjustments made with consideration of the feline senses and species-specific behaviour. Caregivers can prepare cats for a clinic visit with appropriate advice. Waiting rooms, examination rooms, hospital wards and other clinic areas can be designed and altered to reduce stress and hence encourage positive emotions. Changes need not be structural or expensive in order to be effective and make a difference to the cats and, in turn, to cat caregivers and the veterinary team. Moreover, by improving the all-round experience at the veterinary clinic, there are positive effects on preventive healthcare, identification of and recovery from illness, and compliance with treatment. CLINICAL CHALLENGES Good feline healthcare necessitates visiting the veterinary clinic, which, simply by being outside of a cat's territory and familiar surroundings, may lead to negative experiences. Such experiences can trigger negative (protective) emotions and associated physiological stress, which can result in misleading clinical findings, patient distress, prolonged recovery from illness, further difficulties with handling at subsequent visits and potential veterinary personnel injury. There may be a mistaken belief that veterinary clinics must undergo significant renovation or building work to become cat friendly, and that, if species cannot be separated, then clinics cannot improve their care of cats. These Guidelines aim to dispel any such misconceptions and provide detailed practical advice. EVIDENCE BASE These Guidelines have been created by a Task Force of experts convened by the International Society of Feline Medicine and American Association of Feline Practitioners, based on an extensive literature review and, where evidence is lacking, the authors' experience. Endorsements: These Guidelines have been endorsed by a number of groups and organisations, as detailed on page 1161 and at icatcare.org/cat-friendly-guidelines and catvets.com/environment.

'We stick people in a house and say okay, you're housed. The problem is solved': A qualitative study of service provider and organisational leader perspectives on thriving following homelessness. HEALTH & SOCIAL CARE IN THE COMMUNITY 2022; 30:e6018-e6029. [PMID: 36128972 DOI: 10.1111/hsc.14035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/23/2022] [Revised: 07/27/2022] [Accepted: 09/12/2022] [Indexed: 06/15/2023]
Abstract
Research aimed at identifying and evaluating approaches to homelessness has predominately focused on strategies for supporting tenancy sustainment. Fewer studies focus on strategies for enabling thriving following homelessness, and the perspectives of service providers and organisational leaders (SPOL) on this topic are rare. We conducted this study in the context of a community-based participatory research project in two cities in Ontario, Canada. This research was aimed at identifying the strengths and challenges of existing supports in enabling thriving following homelessness, followed by co-designing a novel intervention alongside persons with lived experience of homelessness (PWLEH) and SPOL. The current study presents the findings of interviews conducted in 2020-2021 with SPOL in organisations serving PWLEH. We interviewed 60 individuals including service providers (n = 38; 63.3%) and organisational leaders (n = 22; 36.7%) using semi-structured qualitative interviews. Interviews were conducted and recorded on Zoom to align with physical distancing protocols associated with the COVID-19 pandemic. Recordings were transcribed verbatim and analysed abductively informed by the lenses of social justice and health equity. The essence of our findings is represented by a quote from a research participant: 'We stick people in a house and say okay, you're housed. The problem is solved'. This essence was expressed through five themes: (1) stuck in a system that prevents thriving, (2) substance use as an important coping strategy that prevents tenancy sustainment and thriving, (3) the critical importance of targeting community integration following homelessness, (4) incorporating peer expertise as imperative and (5) people need to be afforded options in selecting housing and services following homelessness. Our findings indicate that SPOL envision possibilities of thriving following homelessness yet are embedded within a system that often prevents them from supporting individuals who are leaving homelessness to do so. Research, practice and policy implications are discussed.

Epidemiology and impact of frailty in patients with atrial fibrillation in Europe. Age Ageing 2022; 51:6670566.

Abstract
BACKGROUND Frailty is a medical syndrome characterised by reduced physiological reserve and increased vulnerability to stressors. Data regarding the relationship between frailty and atrial fibrillation (AF) are still inconsistent. OBJECTIVES We aim to perform a comprehensive evaluation of frailty in a large European cohort of AF patients. METHODS A 40-item frailty index (FI) was built according to the accumulation of deficits model in the AF patients enrolled in the ESC-EHRA EORP-AF General Long-Term Registry. Association of baseline characteristics, clinical management, quality of life, healthcare resources use and risk of outcomes with frailty was examined. RESULTS Among 10,177 patients [mean age (standard deviation) 69.0 (11.4) years, 4,103 (40.3%) females], 6,066 (59.6%) were pre-frail and 2,172 (21.3%) were frail, whereas only 1,939 (19.1%) were considered robust. Baseline thromboembolic and bleeding risks were independently associated with increasing FI. Frail patients with AF were less likely to be treated with oral anticoagulants (OACs) (odds ratio 0.70, 95% confidence interval 0.55-0.89), especially with non-vitamin K antagonist OACs and managed with a rhythm control strategy, compared with robust patients. Increasing frailty was associated with a higher risk for all outcomes examined, with a non-linear exponential relationship. The use of OAC was associated with a lower risk of outcomes, except in patients with very/extremely high frailty. CONCLUSIONS In this large cohort of AF patients, there was a high burden of frailty, influencing clinical management and risk of adverse outcomes. The clinical benefit of OAC is maintained in patients with high frailty, but not in very high/extremely frail ones.

Abstract
INTRODUCTION AND HYPOTHESIS Our objective was to compare mesh exposure rates (4 months and 1 year) after total (TLH) vs supracervical (SLH) laparoscopic hysterectomy at time of minimally invasive sacrocolpopexy (SCP). Secondary outcomes included 30-day complications and midurethral mesh exposure rates. METHODS This a retrospective cohort study at a tertiary care referral center from 2011 to 2018. Subjects were identified using Current Procedural Terminology codes. Demographics, operative characteristics, and perioperative complications were abstracted from medical records. RESULTS Four hundred three women met the inclusion criteria: 91 SLH+SCP and 312 TLH+SCP. Median follow-up was 52 weeks with an overall mesh exposure rate of 1.5%. Follow-up was available for 90% of patients at 4 months and 51% at 1 year. Half of patients had lightweight mesh (n = 203), and half had ultralightweight mesh (n = 200). Vaginal mesh fixation was performed with permanent suture in 86% (n = 344) and delayed absorbable suture in 14% (n = 56) of patients. At 4 months, vaginal mesh exposure rates did not differ between groups (0% SLH vs 1% TLH, p = 1.00). All mesh exposures in the study period occurred with lightweight mesh in the TLH arm. No differences were noted in 1-year mesh exposure rates, 30-day perioperative complications (p = 0.57), or midurethral mesh exposure rates at 4 months (p = 0.35) and 1 year (p = 1.00) between groups. CONCLUSIONS Short-term mesh exposure following SCP with ultralightweight and lightweight polypropylene mesh is rare regardless of type of hysterectomy and much lower than reported in earlier studies with heavier weight mesh. These data suggest TLH at the time of SCP is a safe option in appropriately counseled patients.

Abstract
As a result of the Covid-19 pandemic, medical education institutions were suddenly and unexpectedly faced with making significant changes in delivering their clinical assessments to comply with social distancing requirements and limited access to clinical education centres. Seeking a potential solution to these new circumstances, we designed, implemented and evaluated an online virtual OSCE, as a 'proof of concept' intervention study. Our qualitative research involved document analysis of the stages of decision-making and consultation in designing the intervention, and thematic analysis based on the perspectives and experiences of the key stakeholders (final year students, clinical examiners, simulated patients and faculty staff who acted as station assistants), gathered through surveys with Likert-scale questions and free text comments, and online discussion groups which were recorded and transcribed. From our analysis, we identified four themes: optimising assessment design for online delivery, ensuring clinical authenticity, recognising and addressing feelings and apprehensions, and anticipating challenges through incident planning and risk mitigation. Through the data gathered at each stage of the intervention, and the involvement of key stakeholders in the design and evaluation, our study highlights examples of effective practice for future applications of online technologies in assessment, provides guidance for designing and implementing online virtual assessment, and lays a foundation for comparative, longitudinal research on the significant and increasing roles played by technology in healthcare professional education and practice.

Abstract
Introduction Covid-19 has helped drive all forms of medicine away from traditional brick and mortar medical interactions. Given the availability of online services to obtain treatments for ED, we developed a website to facilitate patient education, triage and men's health appointment scheduling. Objective We sought to assess characteristics of men who utilized a novel website to treat their ED. Methods We report on 50 patients who ultimately booked and attended appointments (video or in person) for erectile dysfunction. Patients found our website through our institution's main informational ED pages or through youtube links from our men's health video playlist library. Patients create an institutional account and are then asked a series of MD created questions designed to streamline patient triage and complete the majority of chart documentation ahead of the appointment. Patients are then sent videos relevant to their condition and future appointment options. Results 2300 users investigated the ED portion of the website with 1.8% of patients ultimately following through with an appointment. 13% of patients who explored the ED portion of the site created a user account that allows a questionnaire to be taken. 90% of men who began the ED questionnaire completed with a mean time of 11 minutes. 52% of men offered an appointment based on their responses completed the patient scheduling form. 71% of traffic was on mobile devices with 29% on desktop/tablet. Site use by time of day is shown in figure 1. Mean age of patients was 53. 92% of patients had ED that occurred > 6 months. Mean SHIM score was 8.2 (IQR 4-12). 80% of participants had both desire and opportunity for sexual activity, 20% did not meet both criteria and thus SHIM scores were less valid for these men. Of the users 28% had never tried pde5s, 32% had partial success with pde5s, 24% could not tolerate or afford pde5s and 42% had unsatisfactory results with pde5s. PDE5 naïve patients were seen by an internal medicine MD specializing in men's health, 10 were seen by surgeons as they requested IPPs and the rest were seen by a combination of men's health APPS and urology attendings for second line treatments and penile doppler. Interestingly, 66% of men were interested in undergoing penile doppler to better understand the etiology of their ED. Hypertension (40%) and diabetes (22%) were the most common medical comorbidities. 36% of the cohort had a strong family history of cardiac disease. Conclusions Men with ED can be effectively triaged through a website application. Most men with pde5 refractory ED wish to pursue penile doppler. The majority of patients seen had watched educational video material ahead of time, facilitating a more sophisticated and streamlined patient interaction. Disclosure No

Abstract
BACKGROUND/AIM This study aimed to identify differences in the pattern and timing of recurrence in patients with advanced ovarian cancer undergoing primary (PDS) or interval debulking surgery after neoadjuvant chemotherapy (NACT). PATIENTS AND METHODS Data were prospectively collected on 105 patients from June 2016 to March 2020. RESULTS There were 30 (50%) recurrences in the PDS group compared to 32 (72.7%) in the NACT group (p=0.020). An intra-abdominal relapse was more common in NACT compared to PDS patients (64.4% vs. 38.3%, p=0.008) and a recurrence in two or more sites (NACT: 44.4% vs. PDS: 23.3%, p=0.010). Among completely cytoreduced patients, a pelvic recurrence was more frequent in NACT patients (NACT: 50% vs. 22.4% in PDS, p=0.011). Progression-free survival (PFS) was longer in PDS compared to NACT (27 vs. 16 months, p=0.039). CONCLUSION NACT patients experienced an unfavorable distribution and timing of recurrent disease compared to patient who underwent PDS.

Abstract
AIMS Black, Asian and minority ethnic women are at higher risk of dying during pregnancy, childbirth and postnatally and of experiencing premature birth, stillbirth or neonatal death compared with their White counterparts. Discrimination against women from ethnic minorities is known to negatively impact women's ability to speak up, be heard and their experiences of care. This evidence synthesis analysed Black, Asian and minority ethnic women's experiences of UK maternity services in light of these outcomes. DESIGN We conducted a systematic review and qualitative evidence synthesis using the method of Thomas and Harden. DATA SOURCES A comprehensive search in AMED, Cinahl, Embase, Medline, PubMed and PsycINFO, alongside research reports from UK maternity charities, was undertaken from 2000 until May 2021. Eligible studies included qualitative research about antenatal, intrapartum and postnatal care, with ethnic minority women in maternity settings of the UK NHS. REVIEW METHODS Study quality was graded using the Critical Appraisal Skills Programme tool. RESULTS Twenty-four studies met the inclusion criteria. Our synthesis highlights how discriminatory practices and communication failures in UK NHS maternity services are failing ethnic minority women. CONCLUSION This synthesis finds evidence of mistreatment and poor care for ethnic minority women in the UK maternity system that may contribute to the poor outcomes reported by MBRRACE. Woman-centred midwifery care is reported as positive for all women but is often experienced as an exception by ethnic minority women in the technocratic birthing system. IMPACT Ethnic minority women report positive experiences when in receipt of woman-centred midwifery care. Woman-centred midwifery care is often the exception in the overstretched technocratic UK birthing system. Mistreatment and poor care reported by many ethnic minority women in the UK could inform the inequalities of outcomes identified in the MBRRACE report.

Abstract
Pelvic organ prolapse (POP) is defined as the descent of one or more of the anterior and posterior vaginal walls, uterus (cervix), or apex of the vagina (vaginal vault or cuff scar after hysterectomy). Although POP can be asymptomatic, if the bulge extends beyond the opening of the vagina, it can have a significant impact on a woman's quality of life. Findings include vaginal bulging toward or through the vaginal introitus that the patient may feel, palpate, or see with a mirror. If a woman is bothered by her prolapse, she should be offered both nonsurgical and surgical treatments.
