Does Surgery Before Pregnancy in Women With Inflammatory Bowel Disease Increase the Risk of Adverse Maternal and Fetal Outcomes? A Danish National Cohort Study.

INTRODUCTION: Up to 15% of women with Crohn's disease (CD) or ulcerative colitis (UC) undergo bowel surgery before pregnancy, and there is little data on pregnancy outcomes in this population. We aimed to assess maternal/fetal outcomes in women with CD or UC who underwent surgeries before pregnancy. METHODS: In this nationwide study, we included all pregnancies in women with CD or UC from 1997 to 2022 and examined 6 categories of CD and UC surgeries before pregnancy. We used multilevel logistic regression to compute crude and adjusted odds ratios (aOR) with 95% confidence intervals (95% CI) for the risk of pregnancy and offspring complications in women who did, vs did not, undergo surgery before pregnancy. RESULTS: There were 833 UC and 3,150 CD pregnancies with prior surgery and 12,883 UC and CD 6,972 pregnancies without surgery. For UC, prior surgery was associated with Cesarian section (C-section) (ileoanal pouch: aOR: 20.03 [95% CI 10.33-38.83]; functional ileostomy: aOR:8.55 [6.10-11.98]; diverting ileostomy: aOR: 38.96 [17.05-89.01]) and preterm birth (aOR: 2.25 [1.48-3.75]; 3.25 [2.31-4.59]; and 2.17 [1.17-4.00]) respectively. For CD and prior intestinal surgery, the risks of C-section (aOR: 1.94 [1.66-2.27]), preterm birth (aOR: 1.30 [1.04-1.61]), and low 5-minute Apgar (aOR: 1.95 [95% CI 1.07-3.54]) increased and premature rupture of membranes (aOR: 0.68 [0.52-0.89]) decreased. For CD with only prior perianal surgery, the risk of C-section (aOR: 3.02 [2.31-3.95]) increased and risk of gestational hypertension/preeclampsia/eclampsia (aOR: 0.52 [0.30-0.89]) decreased. DISCUSSION: Providers should be aware there is an increased likelihood of C-section and certain perinatal complications in patients with CD or UC surgery before pregnancy.

Children born preterm or small for gestational age to mothers with multiple sclerosis: Do these children have an increased risk of infections in early life?

BACKGROUND: Mothers with multiple sclerosis are at increased risk of preterm birth and small for gestational age infants. Both conditions pose a risk of morbidity, including early-life infections. OBJECTIVE: This study aimed to assess the risk of infections in the first 3 years of life among children born preterm or small for gestational age to mothers with multiple sclerosis. METHODS: We used Danish national health registers to establish the study cohort of all births by women with MS born from 1995 to 2023. In Cox regression models, we estimated hazard ratios (HRs) of infections in preterm or small for gestational age children. RESULTS: Preterm children had an adjusted HR of 1.49 (95% confidence interval (95% CI) 1.15-1.93) for hospital-diagnosed infection and 0.88 (95% CI 0.72-1.06) for antibiotic prescriptions. Small for gestational age children had an adjusted HR of 0.81 (95% CI 0.54-1.22) for hospital-diagnosed infection and 1.07 (95% CI 0.82-1.38) for antibiotic prescriptions. CONCLUSION: Children born preterm to mothers with multiple sclerosis had an increased risk of hospital-diagnosed infections in the first 3 years of life, but not of mild-to-moderate infections evaluated on prescriptions. Children born small for gestational age did not have an increased risk of infections.

The impact of iron deficiency on patients under evaluation for colorectal cancer, a prospective cross-sectional study.

BACKGROUND AND OBJECTIVE: Iron deficiency affects more than 60% of colorectal cancer patients at the time of diagnosis. Iron deficiency ultimately leads to anemia, but additionally, iron deficiency might impact other domains of colorectal cancer patients' health and well-being. The aim of this study was to evaluate the impact of iron deficiency on fatigue, quality of life, cognition, and physical ability in patients undergoing evaluation for colorectal cancer. METHODS: Multicenter, prospective, observational cross-sectional study (2021-2023). Fatigue was the primary outcome, measured using the Focused Assessment of Cancer Treatment-Anemia questionnaire (FACT-An). Quality of Life, Cognition, Aerobe capacity, mobility, and peripheral muscle strength were tested as secondary outcomes. Multivariate analysis was performed to estimate the impact of iron deficiency on all outcomes. RESULTS: Two hundred and one patients were analyzed, 57% being iron deficient. In multivariate regression analysis, iron deficiency was not associated with fatigue: FACT-An (r = -1.17, p = 0.57, 25% CI: -5.27 to 2.92). Results on quality of life, cognition, and mobility were non-significant and with small regression coefficients. Iron deficiency showed a nearly significant association with reduced hand-grip-strength (r = -3.47 kg, p = 0.06, 25%CI -7.03 to 0.08) and reduced 6 min walking distance (r = -40.36 m, p = 0.07, 25%CI: -84.73 to 4.00). CONCLUSION: Iron deficiency in patients undergoing evaluation for colorectal cancer was not associated with fatigue, quality of life, or cognition, but might affect aerobic endurance and peripheral muscle strength to a degree that is clinically relevant.

Intestinal ultrasound in patients with suspected Crohn's disease - results of a prospective evaluation by trainees.

BACKGROUND AND AIMS: Intestinal ultrasound (IUS) performed by experts is a valuable tool for the diagnostic work-up and monitoring of Crohn's disease (CD). However, concern about insufficient training and perceived high inter-observer variability limit the adoption of IUS in CD. We examined the diagnostic accuracy of trainee-performed IUS in patients with suspected CD. METHOD: Patients recruited to a prospective trial investigating the diagnostic accuracy of magnetic resonance enterocolonography (MREC) in patients with clinically suspected CD underwent IUS performed by trainees. The primary end-point was IUS per-patient sensitivity and specificity for ileocolonic CD determined by ileocolonoscopy. RESULTS: 129 patients with clinically suspected CD and a complete IC and IUS were included in the analysis. IUS detected signs of CD in 49 cases (small bowel 31, colon 15, small bowel, and colon 3). The sensitivity and specificity for detection of ileocolonic CD by trainee performed IUS improved during the first to the second half of the study period from 57.1% (CI 34.0-78.2) to 73.1% (CI 52.2-88.4) and 76.5% (CI 58.8-89.3) to 89.7% (CI 72.6-97.8). The overall sensitivity and specificity of diagnosing CD with IUS were 65.4% (CI 50.9-78.0) and 80.5% (CI 69.9-88.7). There was no difference in diagnostic performance between IUS and MREC for the detection of CD. CONCLUSION: Trainees improved during the study, and IUS performance in disease detection corresponded to expert-evaluated MREC.Registered at ClinicalTrials.gov (NCT03134586).

Sleep quality and quantity determined by polysomnography in mechanically ventilated critically ill patients randomized to dexmedetomidine or placebo.

BACKGROUND: Abnormal sleep is commonly observed in the ICU and is associated with delirium and increased mortality. If sedation is necessary, it is often performed with gamma-aminobutyric acid agonists such as propofol or midazolam leading to an absence of restorative sleep. We aim to evaluate the effect of dexmedetomidine on sleep quality and quantity. METHODS: Thirty consecutive patients were included. The study was conducted as a double-blinded, randomized, placebo-controlled trial with two parallel groups: 20 patients were treated with dexmedetomidine, and 10 with placebo. Two 16 h of polysomnography recordings were done for each patient on two consecutive nights. Patients were randomized to dexmedetomidine or placebo after the first recording, thus providing a control recording for all patients. Dexmedetomidine was administered during the second recording (6 p.m.-6 a.m.). OBJECTIVE: To compare the effect of dexmedetomidine versus. placebo on sleep - quality and quantity. PRIMARY OUTCOME: Sleep quality, total sleep time (TST), Sleep efficiency (SE), and Rapid Eye Movement (REM) sleep determined by Polysomnography (PSG). SECONDARY OUTCOME: Delirium and daytime function determined by Confusion Assessment Method of the Intensive Care Unit and physical activity. Alertness and wakefulness were determined by RASS (Richmond Agitation and Sedation Scale). RESULTS: SE were increased in the dexmedetomidine group by; 37.6% (29.7;45.6 95% CI) versus 3.7% (-11.4;18.8 95% CI) (p < .001) and TST were prolonged by 271 min. (210;324 95% CI) versus 27 min. (-82;135 95% CI), (p < .001). No significant difference in REM sleep, delirium physical activity, or RASS score was found except for RASS night two. CONCLUSION: Total sleep time and sleep efficiency were significantly increased, without elimination of REM sleep, in mechanically ventilated ICU patients randomized to dexmedetomidine, when compared to a control PSG recording performed during non-sedation/standard care.

Subjective sleep assessment compared to polysomnography in mechanically ventilated critically ill ICU patients.

Sleep deprivation is expected in the intensive care unit (ICU) and is associated with delirium and increased mortality. Polysomnography (PSG) is the gold standard for sleep assessment, but practical issues limit the method. Hence, many ICUs worldwide use subjective sleep assessment (SSA) for sleep monitoring, but the agreement between SSA and PSG is unknown. The hypothesis was that the level of agreement between SSA and PSG was low and that total sleep time (TST) assessed with SSA would be overestimated compared to PSG in this existing cohort database. In this sub-analysis, 30 consecutive study participants underwent 15-h PSG recordings during two consecutive nights. The attending nurse performed an hourly subjective observer rating of sleep quantity during both nights, and the agreement between SSA and PSG was determined along with mean TST. Primary outcome: The level of agreement between SSA and PSG determined by Bland-Altman analysis. Secondary outcome: (1) The overall mean TST estimated by SSA compared to PSG in all study participants enrolled in the main study during both study nights, (2) TST for all study participants evaluated hourly during both study nights, (3) TST assessed with SSA compared to PSG in study participants sedated with dexmedetomidine during the second night and for study participants treated with placebo or non-sedation the first and second nights. The level of agreement between SSA and PSG was low. Mean TST estimated by SSA during the time interval 4.00 p.m. to 7.00 a.m. was 481 min (428;534, 95% CI) vs. PSG at 437 min (386;488, 95% CI) (p = .05). When sedated with dexmedetomidine, TST estimated using SSA was 650 min (571;729, 95% CI) versus PSG which was 588 min (531;645, 95% CI) (p = 0.56). For participants treated with placebo or non-sedation TST estimated with SSA was 397 min (343;450, 95% CI) versus PSG at 362 min (302;422, 95% CI) versus (p = 0.17). In mechanically ventilated critically ill ICU patients, the level of agreement between SSA and PSG was low, and there was a significant overestimation of mean TST. SSA should only be used under awareness that it is imprecise and overestimates TST.

Needs assessment in patients with inflammatory bowel disease in the encounter and communication with healthcare professionals: A fieldwork study.

AIM: To explore how patients with Inflammatory bowel disease experienced encounters with healthcare professionals in two gastrointestinal outpatient clinics to demonstrate what matters in the communication between patients and healthcare professionals. DESIGN: This fieldwork study is part of a larger study developing an application for patients with inflammatory bowel disease in a framework inspired by Participatory Design. Participatory design consists of three phases and this study focused on the first phase, needs assessment. A phenomenological hermeneutic approach and qualitative methods were applied to obtain an understanding of patients' needs. METHODS: Three weeks of participant observations and three focus groups with 14 subjects were conducted at two university hospitals in Denmark. Field notes and interview transcripts were analysed using condensation of meaning and interpreted based on interactional nursing practice theory. The reporting method adhered to the EQUATOR guideline: COREQ. RESULTS: Four themes emerged: Easy and dependable access to healthcare professionals. Predictability of follow-up appointments. Importance of privacy during patient exams and Quality of time spent with healthcare professionals. CONCLUSION: Easy, dependable access, privacy, presence and predictability of follow-up appointments were important to patients with Inflammatory Bowel Disease. IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE: In communication with patients with inflammatory bowel disease, healthcare professionals must be aware of privacy and the importance of predictable follow-up agreements. They must be aware that presence and easy, reliable access positively affect patients' self-care skills. PATIENT CONTRIBUTION: This study is part of a larger project based on Participatory design involving patients and healthcare professionals in the development of technology to support communication.

Preoperative Intravenous Iron Treatment in Colorectal Cancer: Experience From Clinical Practice.

INTRODUCTION: Anemia is associated with increased postoperative morbidity and mortality in abdominal surgery. In clinical trials, preoperative i.v. iron treatment increases the preoperative hemoglobin (Hb) concentration but the effect on transfusion rates are not consistent. This study reports on the experience with preoperative i.v. iron treatment in surgical colorectal cancer (CRC) patients in clinical practice. METHODS: A registry-based cohort study. Surgical colorectal cancer patients with iron deficiency anemia were compared after division into two groups; those who preoperatively received i.v. iron treatment and those who did not. Primary outcomes were preoperative changes in Hb and the difference in perioperative red blood cell transfusion (RBCT) rates. Postoperative complications and mortality rates were analyzed and a descriptive analysis on what triggered blood transfusions were performed. RESULTS: A total of 170 patients were included. Of these, 122 had received preoperative i.v. iron treatment and 48 had not. The perioperative transfusion rate was 45% (55/122) in the treatment group and 40% (19/48) in the control group (non-significant difference). The preoperative changes in Hb levels were not different between the two groups. Transfusion practice appeared more liberal and preceded by higher Hb levels that was guided by the National transfusion guideline. I.v. iron treated patients had a higher rate of postoperative complications. No differences were found on length of stay (LOS) or postoperative mortality. CONCLUSIONS: Preoperative i.v. iron treatment was neither associated with a rise in Hb concentrations at the time of surgery, nor with a reduction in the likelihood of receiving perioperative red blood cell transfusions (RBCT) in colorectal cancer (CRC) patients with iron deficiency anemia.

Physical activity measured by accelerometry in paediatric and young adult patients with inflammatory bowel disease.

OBJECTIVES: Physical activity in paediatric and young adult patients suffering from inflammatory bowel disease (IBD) may play an important role in the overall health status. However, physical activity in these patients has not been reported using objective methods. We aimed to describe accelerometry-measured physical activity levels in paediatric and young adult IBD patients with either ulcerative colitis (UC) or Crohn's disease (CD). METHODS: We recruited Danish patients with IBD aged 10-20 years in clinical remission and with a faecal calprotectin below 200 µg/mg. Physical activity was assessed using tri-axial wrist accelerometry over seven days and quantified using the activity-related acceleration derived as the conventional Euclidian Norm Minus One (ENMO) metric expressed in milli-gravity units (mg). Time spent in Moderate-to-Vigorous Physical Activity (MVPA) was classified as ENMO > 210 mg in 5 s epoch resolution (unbouted). RESULTS: We included 61 patients with a median age of 17 years [Inter Quartile Range, IQR 14-19]. The total volume of activity expressed as average acceleration (ENMO) per day was 31.5 mg (95% CI 29.1-33.9). Time spent in unbouted MVPA was 32 min per day (95% CI 26-37). There was no significant difference in activity volume between patients with UC to patients with CD, the adjusted linear regression coefficient was - 1.7 mg (95% CI -6.2-2.7). Activity volume was higher for males (36.2 mg, 95% CI 31.9-40.5) than for females (27.8 mg, 95% CI 25.6-30.0), and younger patients were more active than older patients; Activity volume in 10-13 year olds was 37.2 mg (95% CI 28.6-45.7), whereas it was 28.5 mg (95% CI 25.2-31.7) for those aged 18-20 years. CONCLUSIONS: We collected tri-axial accelerometry in young patients with IBD in clinical remission, and described their level of physical activity by the conventional ENMO measure. We found no statistically significant difference in patients with UC compared to patients with CD. The volume of physical activity was higher in males compared to females, and inversely associated with age.

Outcome of COVID-19 in hospitalized patients with chronic inflammatory diseases. A population based national register study in Denmark.

OBJECTIVE: COVID-19 has substantial morbidity and mortality. We studied whether hospitalized patients with COVID-19 and chronic inflammatory diseases experienced worse outcomes compared to patients hospitalized with COVID-19 without chronic inflammatory diseases. METHODS: Danish nationwide registers were used to establish a cohort of hospitalized patients with COVID-19 and inflammatory bowel diseases (IBD), rheumatoid arthritis (RA), spondyloarthropathy (SpA), or psoriatic arthritis (PsA) (exposed), and a control cohort without these diseases (unexposed) between March 1, 2020, and October 31, 2020. We compared median length of hospital stay, used median regression models to estimate crude and adjusted differences. When estimating crude and adjusted odds ratio (OR) for continuous positive airway pressure (CPAP) and mechanical ventilation, in-hospital death, 14-day and 30-day mortality, we used logistic regression models. RESULTS: We identified 132 patients with COVID-19 and IBD, RA, SpA, or PsA, and 2811 unexposed admitted to hospital with COVID-19. There were no differences between exposed and unexposed regarding length of hospital stay (6.8 days vs. 5.5 days), need for mechanical ventilation (7.6% vs. 9.4%), or CPAP (11.4% vs. 8.8%). Adjusted OR for in-hospital death was 0.71 (95% CI 0.42-1.22), death after 14-days 0.70 (95% CI 0.42-1.16), and death after 30-days 0.68 (95% CI 0.41-1.13). CONCLUSION: Hospitalized patients with COVID-19 and chronic inflammatory diseases did not have statistically significant increased length of hospital stay, had same need for mechanical ventilation, and CPAP. Mortality was similar in hospitalized patients with COVID-19 and chronic inflammatory diseases, compared to patients hospitalized with COVID-19 and no chronic inflammatory diseases.

Hospitalization for COVID-19 in patients treated with selected immunosuppressant and immunomodulating agents, compared to the general population: A Danish cohort study.

AIMS: In the Danish population, we examined whether patients treated with thiopurines, methotrexate, systemic corticosteroids, anti-tumour necrosis factor (TNF)-α agents, anti-interleukin therapeutic agents, selective immunosuppressive agents and cyclosporine/tacrolimus had an increased risk of hospitalization for COVID- 19, compared to the background population. METHODS: A nationwide cohort study including all people alive in Denmark on 1 March 2020. Exposed patients constituted those exposed to thiopurines (n = 5484), methotrexate (n = 17 977), systemic corticosteroids (n = 55 868), anti-TNF-α agents (n = 17 857), anti-interleukin therapeutic agents (n = 3744), selective immunosuppressive agents (n = 3026) and cyclosporine/tacrolimus (n = 1143) in a period of 12 months prior to 1 March 2020 (estimated time of outbreak in Denmark). We estimated the adjusted risk of hospitalization for COVID-19 for patients treated with the above-mentioned categories of medications, compared to the rest of the population. RESULTS: The adjusted odds ratios of hospitalization in patients treated with corticosteroids and cyclosporine/tacrolimus were 1.64 (95% confidence interval [CI] 1.35 to 2.00) and 4.75 (95% CI 1.96 to 11.49), respectively. The risks of hospitalization in patients treated with thiopurines, methotrexate, and anti-TNF-α agents, were 1.93 (95% CI 0.91 to 4.08), 0.74 (95% CI 0.43 to 1.28), 1.00 (95% CI 0.52 to 1.94), respectively. The number of outcomes in patients treated with anti-interleukin therapeutic agents and selective immunosuppressive agents was too small for analysis. CONCLUSION: Patients treated with systemic corticosteroids and cyclosporine/tacrolimus had a significantly increased risk of being hospitalized for COVID-19. Our study does not uncover whether the increased risk is related to the drug itself, the underlying condition for which the patient is treated or other factors.

Vedolizumab as first-line biological therapy in elderly patients and those with contraindications for anti-TNF therapy: a real-world, nationwide cohort of patients with inflammatory bowel diseases.

BACKGROUND: Data from real-life populations about vedolizumab as first-line biological therapy for ulcerative colitis (UC) and Crohn's disease (CD) are emerging. OBJECTIVE: To investigate the efficacy and safety of vedolizumab in bio-naïve patients with UC and CD. METHODS: A Danish nationwide cohort study was conducted between November 2014 and November 2019. Primary outcomes were clinical remission, steroid-free clinical remission, and sustained clinical remission from weeks 14 through 52. RESULTS: The study included 56 patients (UC:31, CD:25) who initiated treatment with vedolizumab mainly because of contraindications to anti-TNFs, of whom 54.8 and 24.0%, respectively received systemic steroids at the initiation. Rates of clinical remission at weeks 6, 14, and 52 were 32.0, 48.0, and 40.0%, respectively, in UC, and 36.8, 36.8, and 47.4% in CD. Steroid-free clinical remission at week 52 was achieved among 36.0 and 47.4% of UC and CD patients, while sustained clinical remission was achieved in 32.0 and 36.8%. Lack of remission was associated with being female (68.8 vs. 11.1%, p = .01) in UC and non-structuring, non-penetrating behavior in CD (90.0 vs. 44.4%, p = .03); however, this was not confirmed in multivariate analysis. Discontinuation due to primary non-response occurred in 20.0 and 5.3% of UC and CD patients, respectively, while rates of secondary loss of response were 12.0 and 5.3% after 52 weeks of follow-up. Vedolizumab was well-tolerated as only one UC patient experienced a serious adverse event. CONCLUSION: Vedolizumab is effective in the achievement of short-term, long-term, and steroid-free clinical remission in bio-naïve UC and CD patients.

Iron deficiency in colorectal cancer patients: a cohort study on prevalence and associations.

AIM: The aim of this work was to estimate the prevalence of iron deficiency in patients diagnosed with colorectal cancer (CRC) and to clarify its association with patient- and tumour-related characteristics. METHOD: This was a single-centre registry-based cohort study. Iron status was routinely evaluated upon diagnosis of CRC, and these data were coupled with patient- and tumour-specific data from the Danish CRC Group Registry (2013-2018). Data were analysed using multivariate logistic regression. RESULTS: Out of 846 patients, 543 (64%) were iron deficient. There was an association between increasing depth of invasion and iron deficiency, with odds ratios (ORs) of iron deficiency being 2.8 (p = 0.001, CI 1.5-5.1), 4.22 (p < 0.001, CI 2.48-7.18) and 4.63 (p < 0.001, CI 2.30-9.34) for T-stages 2, 3 and 4, respectively. Right-sided tumours had an OR of 3.54 (p < 0.001, CI 2.22-5.67) of iron deficiency compared with left-sided tumours. Tumours diagnosed through the national CRC screening programme were less likely to be associated with iron deficiency (OR 0.34, CI 0.22-0.52), while female gender was associated with an increase in the odds for iron deficiency (OR 1.91, CI 1.33-2.76). Iron deficiency was prevalent in 88% of anaemic patients and 43% of nonanaemic patients. CONCLUSION: Iron deficiency was highly prevalent in patients diagnosed with CRC. Increased depth of tumour invasion, right-sided location and female gender were all associated with higher odds for iron deficiency, while patients diagnosed through the national screening programme were associated with lower odds for iron deficiency. A large proportion of patients with a normal haemoglobin were also iron deficient.

Decreased chance of a live born child in women with rheumatoid arthritis after assisted reproduction treatment: a nationwide cohort study.

OBJECTIVES: No studies have examined the efficacy of assisted reproductive technology (ART) treatment in women with rheumatoid arthritis. Therefore, we examined the chance of live birth after ART treatment in women with rheumatoid arthritis compared with women without rheumatoid arthritis. METHODS: Our cohort study is based on nationwide Danish health registries, comprising all women with an embryo transfer during 1 January 1994 through 30 June 2017. The cohorts comprised 1149 embryo transfers in women with rheumatoid arthritis, and 198 941 embryo transfers in women without rheumatoid arthritis. Our outcome was live birth per embryo transfer, and we controlled for multiple covariates in the analyses. In subanalyses, we examined a chance of biochemical/clinical pregnancy after ART and a possible impact of corticosteroid use prior to embryo transfer. RESULTS: The adjusted OR (aOR) for a live birth per embryo transfer in women with rheumatoid arthritis, relative to women without rheumatoid arthritis, was 0.78 (95% CI 0.65 to 0.92). The aORs for biochemical and clinical pregnancies were 0.81 (95% CI 0.68 to 0.95) and 0.82 (95% CI 0.59 to 1.15), respectively. Corticosteroid prescription prior to embryo transfer increased the OR for live birth (aOR=1.32 (95% CI 0.85 to 2.05)). CONCLUSIONS: The chance of a live birth was significantly reduced in women with rheumatoid arthritis receiving ART treatment, relative to women without rheumatoid arthritis, and our result suggested that the problem was related to an impaired chance of embryo implantation. The role of corticosteroid use prior to embryo transfer must be a subject for further research.

Artificial Intelligence-assisted Analysis of Pan-enteric Capsule Endoscopy in Patients with Suspected Crohn's Disease: A Study on Diagnostic Performance.

BACKGROUND AND AIM: Pan-enteric capsule endoscopy [PCE] is a highly sensitive but time-consuming tool for detecting pathology. Artificial intelligence [AI] algorithms might offer a possibility to assist in the review and reduce the analysis time of PCE. This study examines the agreement between PCE assessments aided by AI technology and standard evaluations, in patients suspected of Crohn's disease [CD]. METHOD: PCEs from a prospective, blinded, multicentre study, including patients suspected of CD, were processed by the deep learning solution AXARO® [Augmented Endoscopy, Paris, France]. Based on the image output, two observers classified the patient's PCE as normal or suggestive of CD, ulcerative colitis, or cancer. The primary outcome was per-patient sensitivities and specificities for detecting CD and inflammatory bowel disease [IBD]. Complete reading of PCE served as the reference standard. RESULTS: A total of 131 patients' PCEs were analysed, with a median recording time of 303 min. The AXARO® framework reduced output to a median of 470 images [2.1%] per patient, and the pooled median review time was 3.2 min per patient. For detecting CD, the observers had a sensitivity of 96% and 92% and a specificity of 93% and 90%, respectively. For the detection of IBD, both observers had a sensitivity of 97% and had a specificity of 91% and 90%, respectively. The negative predictive value was 95% for CD and 97% for IBD. CONCLUSIONS: Using the AXARO® framework reduced the initial review time substantially while maintaining high diagnostic accuracy-suggesting its use as a rapid tool to rule out IBD in PCEs of patients suspected of Crohn's disease.

New surgery and hospital-diagnosed infections in elderly patients with inflammatory bowel disease undergoing surgery - a nationwide cohort study.

BACKGROUND: Elderly patients with inflammatory bowel disease (IBD) are fragile in many aspects. Therefore, in these patients, we studied post-operative complications (new abdominal surgery and serious infections after the first IBD surgery). METHODS: This is a nationwide cohort study based on Danish health registries and included patients with IBD undergoing surgery. The study population was split into ulcerative colitis (UC) and Crohn's disease (CD). The exposed cohort (elderly) constituted those at an age of ≥ 60 years at first IBD surgery, and the unexposed (adults) those with surgery at the age of 18-59 years. We estimated adjusted Hazard Ratios (aHR) of a) new abdominal surgery within 2 years, and b) serious (hospital-diagnosed) infections within 6 and 12 months. We adjusted for several confounders including type of index surgery (laparoscopic or open). RESULTS: The aHR for a new surgery among elderly with UC and CD were 0.69 (95% CI 0.58-0.83) and 0.98 (95% CI 0.83-1.15), respectively. In elderly with UC, the aHRs of infections within 6 and 12 months after surgery were 1.07 (95% CI 0.81- 1.40) and 0.85 (95% CI 0.67-1.08), respectively. In the elderly with CD, the aHRs of infections within 6 and 12 months were 1.45 (95% CI 1.12-1.88) and 1.26 (95% CI 1.00-1.59), respectively. CONCLUSION: The elderly with IBD did not have an increased risk of new abdominal surgery within two years of the first surgery. Elderly with CD, but not UC, had an increased risk of serious infections within 6 months of surgery.

Changes in endoscopic activity and classification of lesions with panenteric capsule endoscopy in patients treated for Crohn's disease - a prospective blinded comparison with ileocolonoscopy, faecal calprotectin and C-reactive protein.

BACKGROUND AND AIMS: Panenteric capsule endoscopy (PCE) is a minimally invasive modality that may replace ileocolonoscopy (IC) in selected patients with Crohn's disease (CD). This study aimed to evaluate the dynamics of repeated assessment with PCE in patients receiving medical treatment for ileocolonic CD. METHODS: This prospective, blinded, multicentre study included patients with endoscopically active CD. Patients were scheduled for IC, PCE, faecal calprotectin and C-reactive protein before and 12 weeks after treatment with corticosteroids or biological therapy. The endoscopic disease activity was assessed with the Simple Endoscopic Score for Crohn's Disease (SES-CD). RESULTS: 31 patients entered the study, and PCE visualized 148 (95.5%) and 128 (82.6%) ileocolonic bowel segments before and after medical treatment, respectively. The median SES-CD decreased from 14 (IQR 8-17) to 5 (IQR 0-14) (P < 0.001) and 14 (IQR 10-17) to 6 (IQR 3-12) (P < 0.001) with IC and PCE, respectively. The repeated measurement correlation between PCE and IC was very strong (r = 0.77, P < 0.001), strong compared to faecal calprotectin (r = 0.42, P = 0.003) and moderate compared to C-reactive protein (r = 0.36, P = 0.005). The mean score for ulcer size, ulcerated surface and affected surface was equal to that of IC before and after treatment. PCE had a sensitivity and specificity of 80.6% (CI 62.5-92.5) and 93.8% (CI 79.2-99.2) for ulcer healing compared to IC. CONCLUSION: PCE is responsive in patients treated for CD and may serve as a minimally invasive alternative to IC in selected patients.

The use of opioids nine months after surgery for Crohn's disease - a nationwide cohort study.

BACKGROUND: The risk of chronic opioid use after surgery for Crohn's disease (CD) is not known. AIM: The aim of this study is to examine the chronic opioid use after surgery according to age at time of surgery and to opioid use prior to surgery. METHODS: This nationwide cohort study included patients with a first surgery for CD (January 1, 1996 through 2021). We examined prescribed opioids 9 months after surgery and estimated adjusted odds ratios (OR) for chronic opioid use in elderly (≥60 years), adults (≥40 and <60 years), and young adults (≥18 and <40 years) according to opioid use prior to surgery. Chronic opioid use was defined as prescriptions in at least two of three consecutive quarters. RESULTS: A total of 797 patients had surgery as elderly, 1603 as adults, and 2786 as young adults. Across all age groups, 18%-38% received opioid prescriptions throughout 9 months after surgery, if opioids were prescribed prior to surgery. If opioids were not prescribed prior to surgery, the corresponding proportions were 2%-5%. If patients were prescribed opioids (≥1) prior to surgery, the adjusted ORs (95% CIs) for their chronic use after surgery in elderly, adults, and young adults were 10.37 (6.77-15.88), 10.48 (7.74-14.19), and 6.55 (4.93-8.72), respectively. CONCLUSION: Clinicians should be aware that in patients with a need for opioids before surgery, the surgery may not change the need for opioids. Future research should examine effective analgesic strategies that help minimise opioid use in this population.

Neonatal outcomes in women with Multiple Sclerosis - Influence of disease activity: A Danish nationwide cohort study.

BACKGROUND: Maternal Multiple Sclerosis (MS) has been associated with an increased risk of adverse birth outcomes. We hypothesized that active disease during conception and pregnancy plays an important role in this context, which this study aims to address. METHODS: We used the Danish registers to conduct a nationwide cohort study. Information on maternal disease activity during pregnancy was retrieved using proxies from the linked registers (hospitalization, magnetic resonance imaging of the brain, and use of systemic corticosteroids during pregnancy). Neonates, exposed in utero to maternal disease activity constituted the exposed cohort and the unexposed cohort constituted neonates without in utero exposure to maternal disease activity. The examined outcomes were preterm birth, small for gestational age, low 5-minute Apgar score, and major congenital anomalies. In logistic regression models we estimated the odds ratios (OR) with adjustment for confounders such as maternal age, comorbidities, parity, smoking, calendar year of birth, and disease-modifying treatment. RESULTS: Among the study population of 2492 children of mothers with MS we identified 273 (11 %) neonates exposed to maternal disease activity during pregnancy, and 2219 (89 %) neonates without exposure to disease activity. The adjusted odds ratios (aOR) for preterm birth, small for gestational age, low 5-minute Apgar score, and major congenital anomalies among children born to women with disease activity during pregnancy were 0.92 (95 % confidence interval (95 % CI) 0.53-1.60), aOR 1.19 (95 % CI 0.62-2.26), aOR 2.57 (95 % CI 0.93-7.15) and aOR 0.93 (95 % CI 0.48-1.83), respectively. CONCLUSIONS: Women with MS having disease activity during pregnancy did not have a statistically significantly increased risk of adverse neonatal outcomes compared to women with MS without disease activity, which is overall reassuring results. We believe, that this will be useful knowledge for patients and clinicians in planning a pregnancy and preparing a birth plan.

Prevalence of Obesity-Related Disease in a Danish Population - The Results of an Algorithm-Based Screening Program.

Purpose: The prevalence of obesity continues to rise. People with obesity are at increased risk of several diseases. We tested an algorithm-based screening program for people with a BMI above 30 kg/m2 and present data on the prevalence of previously undiagnosed obesity-related diseases. Patients and Methods: Seven hundred and sixty-nine persons with BMI > 30 kg/m2 and age 18-60 years were screened for diabetes (assessed by glycosylated hemoglobin and oral glucose tolerance test at HbA1c 43-48 mmol/mol), sleep apnea (screened by questionnaires and assessed by cardiorespiratory monitoring at indication of sleep disorder), liver steatosis or liver fibrosis (assessed by biochemistry and fibroscan) and arterial hypertension (assessed by both office and 24-hour blood pressure measurement). A reference group of people with a BMI of 18.5-29.9 kg/m2 was established. Results: Of those referred, 73.0% were women. We identified new diabetes in 4.2%, prediabetes in 9.1%, moderate-to-severe sleep apnea in 25.1%, increased liver fat and increased liver stiffness in 68.1% and 17.4%, respectively, and hypertension or masked hypertension in 19.0%. The prevalence of diseases was much higher among men and increased with BMI. Except for hypertension, we found few participants with undiagnosed disease in the reference group. Conclusion: An algorithm-based screening program is feasible and reveals undiagnosed obesity-related disease in a large proportion of the participants. The disproportional referral pattern calls for a tailored approach aiming to include more men with obesity. Trial Registration: Inclusion of the non-obese group was approved by the Scientific Ethics Committee of The Region of Southern Denmark (project identification number: S-20210091), and the study was reported at clinicaltrials.gov (NCT05176132).

The number of people with obesity is going up, and they are at a higher risk for various diseases. We tested a screening program for people referred with a BMI over 30 kg/m² and presented the prevalence of diseases related to obesity. We screened 769 people aged 18 to 60 years with a BMI over 30 kg/m² for diabetes (biochemistry and glucose tolerance test), sleep apnea (both questionnaires and home monitoring), liver disease (biochemistry and liver scan) and high blood pressure (office and 24-hour readings). We also tested a reference group of people with BMI 18.5-30 kg/m². Among those screened, 73.0% were women. We found new cases of diabetes in 4.2%, prediabetes in 9.1%, sleep apnea in 25.1%, increased liver fat in 68.1%, increased liver stiffness in 17.4%, and hypertension or masked hypertension in 19.0%. The diseases were more common in men and increased with both higher BMI and age. Except for hypertension, we found few cases in the reference groups. The screening program uncovered undiagnosed obesity-related diseases in a large group of individuals. The uneven distribution of referrals suggests we need a customized approach to include more men with obesity.
