Correlation linking illness perception, negative emotions, and the post-operative recovery effect in patients with perianal disease

BACKGROUND Improvements in the standard of living have led to increased attention to perianal disease. Although surgical treatments are effective, the outcomes of post-operative recovery (POR) are influenced by various factors, including individual differences among patients, the characteristics of the disease itself, and the psychological state of the patient. Understanding these factors can help healthcare providers develop more personalized and effective post-operative care plans for patients with perianal disease. AIM To investigate the effect of illness perception (IP) and negative emotions on POR outcomes in patients with perianal disease. METHODS A total of 146 patients with perianal disease admitted to the First People's Hospital of Changde City from March to December 2023 were recruited. We employed a general information questionnaire, the Brief Illness Perception Questionnaire (B-IPQ), and the Hospital Anxiety and Depression Scale (HADS). We used the 15-item Quality of Recovery Score (QoR-15) to measure patients’ recovery effects. Finally, we conducted Pearson’s correlation analysis to examine the relationship between pre-operative IP and anxiety and depression levels with POR quality. RESULTS Fifty-three (36.3%) had poor knowledge of their disease. Thirty (20.5%) were suspected of having anxiety and 99 (67.8%) exhibited symptoms. Forty (27.4%) were suspected of having depression and 102 (69.9%) displayed symptoms. The B-IPQ, HADS-A, HADS-D, and QoR-15 scores were 46.82 ± 9.97, 12.99 ± 3.60, 12.58 ± 3.36, and 96.77 ± 9.85, respectively. There was a negative correlation between pre-operative IP, anxiety, and depression with POR quality. The influence of age and disease course on post-operative rehabilitation effect are both negative. The impact of B-IPQ, HADS-A, and HADS-D on POR was negative. Collectively, these variables accounted for 72.6% of the variance in POR. CONCLUSION The quality of POR in patients with perianal disease is medium and is related to age, disease course, IP, anxiety, and depression.

THE IMPACT OF VASCULAR RISK FACTORS ON CEREBRAL AMYLOID ANGIOPATHY: A COHORT STUDY IN HEREDITARY CAA AND A SYSTEMATIC REVIEW IN SPORADIC CAA

Background: Cerebral amyloid angiopathy (CAA) has a remarkably variable disease course, even in monogenetic hereditary forms. Our aim was to investigate the prevalence of vascular risk factors and their effect on disease onset and course in Dutch-type hereditary (D-)CAA and sporadic CAA. Methods: We performed a cohort study in D-CAA to investigate the association between vascular risk factors (hypertension, hypercholesterolemia, smoking and alcohol use) and age of intracerebral hemorrhage (ICH) onset and time of ICH recurrence with survival analyses. In addition, we performed a systematic review to assess the prevalence of vascular risk factors and their effect on clinical outcome in sporadic CAA. We searched PubMed, Embase, Web of Science and COCHRANE Library, from 1987-2022 and included cohorts with ≥10 patients. We created forest plots, calculated pooled estimates and reported variability (heterogeneity plus sampling variability) and risk of bias. Results: We included 70 participants with D-CAA (47% women, mean age 53y). Sixteen (23%) had hypertension, 15 (21%) hypercholesterolemia, 45 (64%) were smokers and 61 (87%) used alcohol. We found no clear effect of vascular risk factors on age of first ICH (log-rank test hypertension: p=0.35, hypercholesterolemia: p=0.41, smoking: p=0.61 and alcohol use: p=0.55) or time until ICH recurrence (log-rank test hypertension: p=0.71, hypercholesterolemia: p=0.20 and smoking: p=0.71). We identified 25 out of 1234 screened papers that assessed the prevalence of risk factors in CAA and 6 that reported clinical outcomes. The pooled prevalence estimates of hypertension was 62% (95%CI:55%-69%), diabetes 17% (95%CI:14%-20%), dyslipidemia 32% (95%CI:23%-41%), and tobacco use 27% (95%CI:18%-36%). One study reported study diabetes and hypertension to be associated with a lower risk of recurrent ICH, whereas another study reported hypertension to be associated with an increased risk. All other studies showed no association between vascular risk factors and clinical outcome. High quality studies focusing on vascular risk factors were lacking. Conclusions: In patients with D-CAA and sporadic CAA the prevalence of vascular risk factors is high. Although this suggests an opportunity for prevention, there is no clear association between these risk factors and CAA-related ICH onset and recurrence.

Spesolimab decreases generalized pustular psoriasis (GPP) body surface area (BSA) over time in patients with various lengths of disease history: Results from the EFFISAYIL® 2 trial

Generalized pustular psoriasis (GPP) is a chronic inflammatory, potentially life-threatening skin disease. Most patients experience chronic skin symptoms between flares which can lead to significant patient burden. Spesolimab, an anti-interleukin-36 receptor monoclonal antibody, is approved in the United States to treat GPP in adults and pediatric patients 12 years of age and older and weighing at least 40 kg. EFFISAYIL® 2 (NCT04399837) evaluated the efficacy and safety of subcutaneous (SC) spesolimab in GPP. Here, we report the effects on GPP body surface area (BSA) over time in patients diagnosed <5 vs ≥5 years prior to enrollment when treated with the FDA approved spesolimab dosing regimen (600 mg loading dose, then 300 mg maintenance dose every 4 weeks) in EFFISAYIL® 2. Total BSA was determined based on a weighted average of the extent of involvement over 4 main body regions, with head = 10%, upper extremities = 20%, trunk = 30%, and lower extremities = 40%. Total BSA involvement was calculated for each subject at 4 timepoints (baseline, Week 4, Week 16, and Week 48). Data collected closest to the given time points were used by including the effect of potential intravenous spesolimab treatment and subsequent open-label SC spesolimab treatment in patients who experienced a flare. The data were analyzed as observed. Within the FDA approved regimen spesolimab group, average BSA for patients diagnosed with GPP for <5 years (N=13) was 14.7 at baseline, 15.0 at Week 4, then decreasing to 11.7 at Week 16, and then to 5.0 at Week 48. For patients diagnosed with GPP for ≥ 5 years (N=17) the values were 12.3 at baseline, decreasing to 7.0 at Week 4, increasing slightly to 7.6 at Week 16, and decreasing to 4.1 at Week 48. Total BSA involvement decreased over the 48 weeks of the trial in spesolimab-treated patients regardless of whether they were early (< 5 years) or late (≥ 5 years) in their disease course. This finding demonstrates the efficacy of spesolimab in controlling GPP consistently for patients with various lengths of disease history.

The impact of diet on the inflammatory bowel disease course – a literature review

Introduction and Objective. Inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn’s disease (CD), is a chronic gastrointestinal disorder marked by relapsing symptoms. Current treatments mainly involve immunosuppressive therapies, which are effective but may have significant side effects. Diet as an adjunctive treatment is appealing due to its accessibility, low cost, and minimal adverse effects. This review explores the role of diet in managing IBD, focusing on dietary strategies during both active disease and remission. Methods. A literature review was conducted using PubMed and Google Scholar with search terms like "inflammatory bowel disease", "Crohn’s disease", "ulcerative colitis", "diet", "IBD treatment", "anti-inflammatory food" and related variations. Articles published within the last five years were prioritized. Brief description of the state of Knowledge. Ulcerative colitis and Crohn’s disease cause gastrointestinal inflammation. Crohn’s disease symptoms include abdominal pain, fistulas and rectal lesions, while UC is characterized by diarrhea, severe discomfort, and blood in the stool. Certain foods often exacerbate IBD symptoms. Proper nutrition during disease stages can improve patients’ quality of life. Diets high in processed foods, sugar, and red meat may increase IBD risk, while fiber and vitamin D3 are associated with fewer flare-ups. Regular malnutrition screening is essential for all IBD patients. Conclusions. Understanding the dietary components that influence inflammation in IBD could lead to better treatment outcomes and longer-lasting symptom relief. Integrating nutrition into personalized treatment strategies should become standard practice for managing IBD.

Disease activity at the onset of diagnosis as a predictor of disease outcomes in a cohort of patients with systemic lupus erythematosus: A post hoc retrospective analysis of the COMOSLE-EGYPT study.

Systemic lupus erythematosus (SLE) has a non-uniform course directly reflected in changes in disease activity and anticipation of damage. To determine the impact of disease activity at the onset of disease diagnosis, measured by the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) disease activity score, on different disease parameters and outcomes. This multicentre, retrospective cohort study included 823 SLE patients. Disease damage was measured by the Systemic Lupus International Collaborating Clinics Damage Index (SLICC), and comorbidities were measured by the Charlson Comorbidity Index (CCI). According to the mean SLEDAI at onset of disease diagnosis, patients were classified into two groups: I included patients with a mean SLEDAI ≤ 10 (non-severe disease activity), and II included patients with a mean SLEDAI > 10 (severe disease activity). SLEDAI at onset of disease diagnosis was a predictor of damage and comorbidities. A higher SLEDAI score at onset of disease diagnosis was associated with damage accrual. Patients who are younger at disease onset are more likely to have more severe disease. Severe disease activity at the onset of disease diagnosis was also associated with future comorbidity occurrences, but it was not significantly associated with mortality. SLEDAI at the onset of disease diagnosis could be a prognostic marker predicting the damage, which may help in the identification of patients who are at higher risk of adverse outcomes. Special care should be directed towards patients who are younger at disease onset as they may have a higher disease activity at diagnosis. Key Points • This is a unique study as it is the first to focus on the impact of SLE disease activity at the onset of disease diagnosis measured by SLEDAI disease activity score on different disease parameters and outcomes. • Previous studies, though these are scarce, have highlighted the impact of disease activity throughout the disease course and not specifically at the beginning of the SLE disease.

Psycho-Neuro-EndocrinE-Immunology Therapy of Cancer, Autoimmunity, Geriatric Disorders, Covid-19, and Hypertension.

Despite the great number of experimental investigations in the area of psycho-neuro-endocrine-immunology showing that endocrine, nervous, and immune systems cannot be in vivo physiologically separated, the diagnosis and therapies of the pathologies of these three functional biological systems continue to be separately performed from a clinical practice point of view. The separation between experimental and clinical medicine became dramatic after the discovery of more than 10 human molecules provided by anti-inflammatory and antitumor activity, completely devoid of any toxicity, which may be subdivided into three fundamental classes, consisting of the pineal indole, beta-carboline, and methoxy-kynuramine hormones. Moreover, human systemic diseases, including cancer, autoimmunity, and cardiovascular pathologies, despite their different pathogenesis and symptomatology, are commonly characterized by a progressive decline in the endogenous production of pineal hormones, endocannabinoids, and Ang 1-7, with a consequent inflammatory status and diminished natural resistance against cancer. Then the evaluation of the functional status of the pineal gland, the endocannabinoid system, and ACE2-Ang 1-7 axis should have to be included within the laboratory analyses for the systemic diseases. Finally, the correction of cancer- and autoimmunity-related neuroimmune and neuroendocrine alterations could influence the clinical course of systemic diseases. In fact, preliminary clinical results would demonstrate that the neuroimmune regimen with pineal hormones, cannabinoids, and Ang 1-7 may allow clinical benefits also in patients affected by systemic pathologies, including cancer, autoimmunity, and cardiovascular diseases, who did not respond to the standard therapies.

Characteristics of cutaneous manifestations in immunoglobulin a vasculitis and their relationships with system involvement and treatment needs.

The characteristics of cutaneous manifestations in IgAV patients may be helpful in predicting the course of the disease. The skin lesion type, distribution and persistence of cutaneous manifestations in IgAV are associated with system involvement. In addition, the need for intensive therapy increases in the presence of vesicles/bullae, necrosis/ulcer, rash spreading over the buttocks and persistent rash in IgAV. • Palpable purpura localized to the lower extremities is the expected cutaneous manifestation of immunoglobulin A vasculitis. • The type, distribution and duration of rash in IgAV have effects on theimmunoglobulin A vasculitis disease course. • Genital tract involvement is more common in patients with necrosis/ulcers. • Gastrointestinal tract involvement and genital tract involvement are more commonin patients with rash spreading above the buttocks. • Renal involvement is more common in patients with persistent rash.

Diagnostic and Therapeutic Challenges of Focal Cortical Dysplasia in Mali: A Case Report

Focal Cortical Dysplasias (FCDs) are a common cause of pharmaco-resistant epilepsy. FCDs are rare conditions, and their pathogenesis remains poorly understood. We report a 12-year-old patient seen in our clinic for focal onset epileptic seizures. Neurological examination and brain CT-scan were nearly normal. However, an electroencephalogram (EEG) revealed a slightly slow background rhythm with slow spikes in the medial and right parietal regions and a brain magnetic resonance imaging (MRI) showed a focal cortical thickening in the right parietal lobe with FLAIR hypersignal, indicating a focal cortical dysplasia. Ongoing seizures marked the disease course under antiepileptic polytherapy after 15 months of treatment. Keywords: Focal cortical dysplasia, pharmaco-resistant epilepsy, Mali, Africa.

Protective Potential of Sodium-Glucose Cotransporter 2 Inhibitors in Internal Medicine (Part 1)

Sodium-glucose cotransporter 2 inhibitors (SGLT2i) have emerged as a revolutionary class of drugs with far-reaching protective effects in multiple organs. The protective potential of SGLT2i is much broader than that of the classical concept of glucose control and consists of an entire conglomerate of associated pleiotropic effects. This study aims to provide a descriptive review of the pleiotropic therapeutic potential of SGLT2i. The first part of the literature review examined the use of SGLT2i in cardiology and nephrology. The use of SGLT2i represents an innovative approach to improving patients’ quality of life and course of heart failure and chronic kidney disease, regardless of left ventricular ejection fraction and type 2 diabetes.

Clinical evaluation of periodontium tissues in the patients with low bone mineral density

Summary. Diagnostics and treatment of periodontal diseases remain a topical problem of modern dentistry, the issue of their relationship with the changes in dento-alveolar complex and bone system is requiring thorough study. The aim of the study – to study the condition of periodontium tissues in the patients with low bone mineral density. Materials and Methods. 242 patients (116 men and 126 women), aged 18–60 years, have been examined. The females, in their turn, have been divided into 2 groups: Group 1 – 61 women of reproductive age, aged 18–49 years; Group 2 – 65 women, aged 50–60 years, with three and more postmenopausal years. Results and Discussion. Uniform prevalence and nosological structure of periodontium tissue diseases have been found both in males and females, the frequency of periodontium disease detection being 85.34 percent for men and 88.88 percent – for women, р>0.05. However, the intensity of the course of dystrophic and inflammatory lesions of periodontium tissues was much more pronounced in females as compared with males that was confirmed by index assessment of periodontal indices. Conclusions. Thus, high prevalence of periodontium tissue diseases (87.19±2.14) percent has been found in the patients with low bone mineral density, the intensity of disease course being much more pronounced in females in contrast to males.

Rapid Disease Progression of Myelodysplastic Syndrome is Reflected in Transcriptomic and Functional Abnormalities of Bone Marrow MSCs.

Bone marrow (BM) mesenchymal stromal cells (MSCs) are important regulators of hematopoietic stem and progenitor cells (HSPCs). When transformed to a dysplastic phenotype, MSCs contribute to hematopoietic diseases such as myelodysplastic syndromes (MDS), but it remains unclear if there are specific properties in MDS-MSCs that contribute to the disease course. To understand this, we investigated MDS-MSCs from fast (MDSfast) vs slow (MDSslow) progressing disease groups and discovered differences between these groups. MDSfast-MSCs secrete more inflammatory factors, support myeloid-skewed differentiation of HSPCs, and importantly, show poorer response to hypomethylation as a key differentiator in GSEA analysis. When exposed to long-term in vivo stimulation with primary MDSfast-MSCs-based scaffolds, healthy donor (HD) HSPCs show elevated NF-κB expression, similar to leukemic HSPCs in MDS. Those "MDSfast-MSCs-primed" HD-HSPCs continue to show enhanced engraftment rates in secondary MDS-MSC-based scaffolds, providing evidence for the microenvironmental selection pressures in MDS towards leukemic HSPCs. Together, our data point towards a degree of co-development between MSCs and HSPCs during the progression of MDS, where changes in MDS-MSCs take place mainly at the transcriptomic and functional levels. These unique differences in MDS-MSCs can be utilized to improve disease prognostication and implement targeted therapy for unmet clinical needs.

On the Prognostic Implication of Delays in the Definitive Treatment of Uveal Melanoma

Background: Recent studies suggest that delays in the definitive treatment of uveal melanoma may increase the risk of metastatic disease. This topic has been the subject of considerable debate. Methods: In this study, we combine and contrast medical evidence from several recent publications seeking to clarify the association between treatment delays and prognosis. Results: Emerging evidence indicates that metastatic seeding may continue until the primary tumor is effectively treated. Metastases that arise later in the disease course may carry additional genetic aberrations, enhancing their capacity to establish fatal macrometastases. Importantly, previous reports of shared mutations between primary tumors and metastases should not be interpreted as evidence that all metastases are seeded early. On the contrary, some tumors acquire additional driver mutations in the later stages, which are subsequently shared between the primary tumors and metastases. The increased risk of metastasis in patients with local tumor recurrence further highlights the importance of timely treatment. Additionally, new data on circulating tumor cells and treatment timing challenge the traditional practice of observing small melanomas. Conclusions: Observation is still warranted for indeterminate lesions to confirm malignancy. However, once a melanoma diagnosis has been established, further observation is harmful, and treatment should be administered as soon as reasonably possible.

Gender differences in periodontal pocket microflora in patients with chronic generalized periodontitis

Background: Periodontal disease, the primary cause of tooth loss, is a critical public health concern with a considerable impact on quality of life. It is of interest to explore gender differences in the course of inflammatory periodontal diseases, as well as the prospects of their personalized treatment and prevention in males and females. Aim: To assess the dental health and quantitative composition of periodontal pocket microflora in periodontitis patients, taking into account gender differences. Materials and Methods: The study included 39 patients with moderate chronic generalized periodontitis aged 40–60 years. The diagnosis was made using both primary and secondary dental diagnostic tools. The study had two groups: males (41%, n=16) and females (59%, n=23). The following parameters were assessed: oral hygiene index (OHI-S), severity of gingival inflammation (PMA), and quantitative composition of periodontal pocket microflora (DENTOSCREEN, “Lytech” Co. Ltd., Russia), taking into account gender differences. The study findings were statistically processed using Microsoft Office Excel 2016 with Data Analysis and AtteStat 12.0.5 add-ins. The Shapiro–Wilk test was used. The data are presented as median and interquartile range: Me [Q1; Q3]. The frequency of microorganisms is presented as percentage of the mean and standard error of the mean. The confidence interval was calculated using the Wald method, according to the formula for proportions and frequencies. For small values, the Wald method with Agresti–Coull correction was used. Samples were compared using the following tests: the Mann–Whitney U test was used for quantitative data and Fisher’s angular transformation (φ*emp) for frequency (nominal) attributes. Significant differences were defined as a probability 95% (p 0.05). Results: The quantitative composition of periodontal pocket microflora in patients with moderate periodontitis revealed significant gender differences, as demonstrated by an increase in the count of Fusobacterium nucleatum and Prevotella intermedia, as well as the frequency of Porphyromonas gingivalis, in males compared to females (φ*emp=1.736; p 0.05). Dental health indices confirmed the hypothesis of significant differences between males and females in terms of plaque index (OHI-S) and РМА. In males, poor oral hygiene was reported in 93.7% cases, which was significantly higher (φ*emp=2.04; p 0.05) than in females (69.6%). Moderate gingival inflammation was more prevalent in males, while mild gingival inflammation was more prevalent in females (p 0.05). Conclusion: The study findings emphasize the importance of oral hygiene in the prevention of chronic periodontitis and can be used to improve complex treatment algorithms for patients with periodontal diseases. This includes more frequent dental check-ups and professional oral care sessions, as well as oral hygiene training and monitoring, in males compared to females. Diagnosis by polymerase chain reaction allows for the identification and quantitative determination of DNA from periodontopathogenic bacteria at low concentrations, as well as the justification of treatment algorithms and prediction of treatment outcomes.

Cannabinoid Receptor type 2 agonist GP1a attenuates macrophage activation induced by M. bovis-BCG by inhibiting NF-ĸB signaling.

Tuberculosis (TB) is one of the leading causes of death worldwide and a major public health problem. Immune evasion mechanisms and antibiotic resistance highlight the need to better understand this disease and explore alternative treatment approaches. Mycobacterial infection modulates the macrophage response and metabolism to persist and proliferate inside the cell. Cannabinoid receptor type 2 (CB2) is expressed mainly in leukocytes and modulates the course of inflammatory diseases. Therefore, our study aimed to evaluate the effects of the CB2-selective agonist GP1a on irradiated M. bovis-BCG (iBCG)-induced J774A.1 macrophage activation. We observed increased expression of CB2 in macrophages after iBCG stimulation. The pretreatment with CB2-agonists, GP1a, JWH-133, and GW-833972A (10 µM), reduced iBCG-induced TNF-α and IL-6 release by these cells. Moreover, the CB2-antagonist AM630 (200nM) treatment confirmed the activity of GP1a on CB2 by scale down its effect on cytokine production. GP1a pretreatment (10 µM) also inhibited the iBCG-induced production of inflammatory mediators as prostaglandin (PG)E2 and nitric oxide (NO) by macrophages. Additionally, GP1a pretreatment also reduced the transcription of proinflammatory genes (inos, il1b, cox2) and genes related to lipid metabolism (dgat1, acat1, plin2, atgl, cd36). Indeed, lipid droplet accumulation was reduced by GP1a treatment which was partially blockade by AM630 pretreatment. Finally, GP1a pretreatment reduced the activation of the NF-κB signaling pathway. In conclusion, the activation of CB2 by GP1a modulated the macrophage response to iBCG by reducing inflammatory mediator levels and metabolic reprogramming.

Predictive value of 68[Ga]Ga-DOTA-TATE PET/CT volumetric parameters in assessing treatment response to long-acting somatostatin analogues in patients with well-differentiated neuroendocrine tumours.

Over the past decade, numerous treatment options have emerged for patients with locally advanced and metastatic neuroendocrine tumours (NETs). Nevertheless, the optimal timing of treatment interventions remains uncertain, given the highly variable disease course observed in these patients, even when patients have the same tumour stage and grade. The aim of the study was to evaluate the predictive role of standardized uptake values (SUVs) and volumetric parameters obtained from pretreatment [68Ga]Ga-DOTA-TATE for response to SSA therapy in patients with NET. In this retrospective study, we included 42 patients (21 women, 21 men; age range: 46-84years) with histologically confirmed, metastatic, NET (G1 13, G2 28 cases); median Ki-67 index 5%, range 1-16) who received long acting SSA as a first line treatment and underwent [68Ga]Ga-DOTA-TATE PET/CT before SSA treatment. For all [68Ga]Ga-DOTA-TATE avid lesion SUVmax, SUVmean, somatostatin receptor expression tumour volume (STV), total lesion somatostatin receptor expression (TLD, STV multiplied by SUV mean) and Tmean/Smean (SUVmean of tumours/metastases divided by SUVmean of normal spleen) were measured. Finally, the sum of STV (total STV, TSTV) and TLD (total TLD, TTLD) was calculated for each patient and used in the analysis. During the study period, 14 patients had stable disease (33.3%) and 28 patients experienced progression (66.7%), among whom 12 patients died. The median progression-free survival (PFS) and overall survival (OS) were 26.5 and 46.5months, respectively. In the univariate and multivariate analysis, in the whole population study, Tmean/Smean ratio (HR 1.88, 95% CI 1.06-3.35, p = 0.03), Ki-67 index (HR 1.14, CI 1.03-1.26, p = 0.01) and pre-treatment chromogranin A serum concentration (HR 1.01, CI 1.0-1.03, p = 0.01) were significantly associated with PFS. Among patients with small intestinal NETs, TSTV (< 125.85 cm3 vs. ≥ 125.85 cm3, p = 0.023) and TTLD (< 4168.95 vs. ≥ 4168.95, p = 0.026) were significantly associated with PFS in the univariate analyses. No significant correlation was found between measured volumetric parameters and OS. Volumetric parameters of pretreatment 68[Ga]Ga-DOTA-TATE PET/CT may be useful in prediction of the response to SSA (used in monotherapy as a first-line therapy) in patients with NET.

Combined [18F]-FDG PET-MR Imaging: A promising tool for diagnostics of small bowel Crohn's disease.

Introduction Diagnostics of small bowel Crohn's disease (CD) can be difficult. Combined positron emission tomography-magnetic resonance enterography (PET-MRE) can be used to evaluate intestinal metabolism, but clinical use has been limited due to accessibility, costs, absence of standardized methods and diagnostic thresholds. Our aim was to show that combined PET-MRE can be used to diagnose active small bowel CD. Methods We performed a fusion PET-MRE-scan with [18F]-FDG-tracer to 30 patients with suspected small bowel CD in colonoscopy. Standardized uptake values (SUV) were measured from small bowel. The diagnosis was confirmed with small bowel capsule endoscopy. Clinicians chose appropriate medication to each patient blinded from SUV-results. Endoscopic, laboratory and MRE-findings were investigated in relation to SUV. Results Fusion PET-MRE outperformed MRE in diagnostic accuracy. Patients diagnosed with CD (N=24) had higher SUV than patients not diagnosed with CD (N=6) (3.34 vs. 1.84, p=0.022). A diagnostic cut-off at SUV at 2.5. could be used (AUROC=0.81). A higher SUV predicts need for immunosuppressive medication (p=0.0026) and biologics (p=0.0005). SUV correlates positively with SES-CD-score (Simple Endoscopic Score for Crohn's Disease), fecal calprotectin and CRP and negatively with Hb and serum albumin. Conclusion In future, [18F]-FDG PET-MRE can be used in diagnostics of small bowel CD as a safe alternative for capsule endoscopy. High SUV can predict a more progressive disease course and need for more advanced therapies.

Chronic Spontaneous Urticaria—New Predictor on the Horizon?

Chronic urticaria is one of the most common diseases in allergology and dermatology practice with unclear causes of occurrence. Background: Some studies emphasize the correlation between inflammation in chronic urticaria and disturbed intestinal microbiota. It raises the question about the role of some intestine-related substances in the pathogenesis of urticaria as well as their potential role as disease predictors. Calprotectin is an acute-phase protein with a well-established diagnostic position in the field of gastroenterology. There are some data on the relationship between this parameter and gut microbiota. The major aim of this preliminary study is to investigate whether calprotectin can be potentially taken into account as a disease course predictor in urticaria. Methods: We included in our study 54 chronic spontaneous urticaria (CSU) patients (of whom 26 manifested the symptoms of recurrent angioedema) and 29 patients allergic to Hymenoptera venom for the reference group (in these patients, before venom immunotherapy induction, full diagnostics is performed including intestinal problems). Disease activity in the CSU patients was assessed using the Urticaria Activity Score (UAS) and the disease control in this group was assessed with the Urticaria Control Test (UCT). Moreover, we analyzed fecal and serum calprotectin concentrations. Results: Positive correlation was found only between the values of serum calprotectin concentration and the control level of CSU symptoms with the lack of other relations. Conclusions: Our results do not supply unequivocal evidence for calprotectin as a potential marker of CSU course, though this concept, in the light of growing evidence for microbiota’s role in urticaria, requires further research.

BN SO35 - A Novel Ambulatory Pathway in the Management of Acute Pancreatitis

Abstract Background Acute Pancreatitis (AP) accounts for 20000 admissions per year, resulting in an average hospital stay of 5 days. Over 90% of patient have mild or moderate disease severity. Validated risk stratification tools such as the Harmless Acute Pancreatitis (HAP) score utilised alongside biochemical markers and clinical acumen can predict up to 97% of patients with a mild disease course. A pathway was introduced at two NHS centres to enable diagnosis and ambulatory management of patients with predicted mild AP with the aim of improving patient experience by preventing unnecessary admission, reducing pressure on surgical departments and providing safe outpatient management. Method The study took place at two sites: a district general hospital (DGH) and a tertiary referral centre. Pathway development occurred in parallel to pilot. Ambulation was defined as no overnight stay in a hospital bed. An initial retrospective review of all AP admissions was undertaken to understand current burden of disease and severity in our centres. Suitable patients were identified prospectively and data (demographics, biochemical markers, modified HAP score, severity of disease, complications, re-admission rate, surgical or endoscopic intervention) were collected for up to 30 days after discharge. AP ‘proforma’ were created to understand surgeons decision-making surrounding ambulation versus admission. Results Between November 2023 and May 2024, 99 patients with AP presented to the DGH surgical unit. Causes of AP included gallstones (n=55), idiopathic (n=21), alcohol (n=17), and post-ERCP (n=2). 38 patients (38%) were ambulated, with 23/38 (61%) returning for planned review within 72 hours. There were no mortalities in the ambulatory group. Three (7%) ambulated patients were re-admitted within 30 days for pain control (n=2) and post-cholecystectomy complications (n=1). Reasons for non-ambulation included: pain (n=30), inpatient cholecystectomy (n=4), poor oral intake (n=4), social reasons (n=3). In 4-week tertiary data collection, 5/17 (29%) eligible patients were ambulated, with 1 (20%) re-admission. Conclusion Pilot of a novel pathway to identify and ambulate patients with a predicted mild course of AP has been successful across two NHS centres. Use of validated risk scores alongside biochemical markers and clinical acumen produces a safe, sustainable and effective pathway that reduces burden on inpatient surgical resources. It is safe and feasible to ambulate patients with AP whilst undertaking diagnostic imaging, managing symptoms, facilitating expedited cholecystectomy and arranging specialist review in the outpatient setting. Further work is required with stakeholders to refine the pathway and replicate these results in other surgical units.

Retreatment of Multiple Myeloma with Previously Refractory Drugs.

As patients with relapsed/refractory multiple myeloma (RRMM) continue to live longer, they might get exposed to most available drugs and drug classes during the disease course. For such late line RRMM or among patients without access to novel therapies, retreatment with a drug that the disease had previously been refractory to might be one option. In this retrospective study, we describe 315 patients with RRMM at our institution that were retreated with a drug that the disease had been previously refractory to. We found an overall response rate of 56.2%, and a median progression free survival (PFS) of 11 months with retreatment. Patients with a longer time on initial therapy with the index drug (>28.4 months) had a superior PFS with retreatment (median PFS 16.9 months vs 8.1 months, p<0.001). Similarly, patients with a longer time gap between the initial line of therapy with index drug and retreatment with index drug (>46.1 months) had a better PFS with retreatment (28.2 vs 8.9 months, p=0.016). In conclusion, retreatment with a previously refractory drug is a viable therapeutic option for RRMM, with the most significant benefit derived in disease demonstrating sensitivity to initial drug exposure, and among those with a longer gap between initial drug exposure and retreatment.

Different Evaluation Strategies of Oncological CT Examinations with Regard to Professional Experience: A Clinical Study Using Eye-tracking.

Contrast-enhanced CT is the standard imaging technique in oncological objectives. Rates of missed pathologies depend on work experience of the respective radiologists. Thus the aim of this study is to analyze the eye movements of professionals while reading CT images in order to evaluate whether the eye-fixation patterns and search strategies of experienced radiologists could explain higher detection rates of pathologies and whether such patterns can be learned.Anonymized images of 10 patients were presented to three medical students and six radiologists with different levels of work experience. During image analysis, ocular fixation positions were recorded using an eye-tracking software tool. The CT scans were analyzed retrospectively, considering the individual course of disease with the issue of successful detection of all pathologies. Visual attention and dwell time of ocular fixation on clinically important abnormalities or areas with pathological findings, general search patterns, and time efficiency were assessed. For statistical analysis, interobserver variability and accuracy of lesion detection were evaluated taking into account individual experience.The results revealed that observer sensitivity depends on work experience due to a more systematic order of inspection and a well-known course of disease, e.g. in case of metastatic spread. The areas of missed pathologies mostly included secondary findings. Inexperienced readers changed the stratification considerably more often and required more time for reporting or detecting pathologies.Our results suggest that experienced radiological physicians reduce their amount of missed findings by looking more systematically at images and by applying a more targeted inspection of clinically important regions. · CT interpretation by radiology residents is faster and less error-prone compared to postgraduate residents. · systematic image analysis is trainable. · engrams tend to be acquired through experience. · Kluge S, Schülke C, Ites HC et al.
