Multimodality imaging approach of patent foramen ovale: Practical considerations for transient ischemic attack/stroke.

A patent foramen ovale, which is present in up to 25% of the population, is a risk factor for cryptogenic stroke (which accounts for 15%-40% of strokes) and transient ischemic attack via paradoxical embolism. This narrative review focuses on the multimodality imaging approach of the diagnosis and periprocedural guidance of patent foramen ovale, with an emphasis on the use of agitated saline as contrast medium in echocardiography, starting from embryologic aspects. Therefore, we aimed to make a concise and complete presentation of the protocol used for this type of evaluation, along with multimodality imaging approach of the patent foramen ovale and practical considerations for transient ischemic attack/stroke.

Impact of COVID-19 Pandemic on the Quality of Life of IBD Patients.

Background and Objectives: The COVID-19 pandemic has had a considerable impact on inflammatory bowel disease (IBD) patients by limiting their access to medical services due to restrictions and the reorganization of the healthcare systems, which affects their quality of life (QoL). We aimed to assess the impact of the COVID-19 pandemic on the QoL of patients with IBD. Materials and Methods: We conducted a descriptive observational study, which included 90 adult patients diagnosed with IBD. The study sample consisted of two subgroups: a retrospective-pre-pandemic group (group A) and a prospective-pandemic group (group B). Group A included 45 IBD patients who were evaluated in 2018. Group B included 45 patients with confirmed diagnosis of IBD, evaluated between June and December 2021­the period of the COVID-19 pandemic (prospective), consecutively recruited. All the patients filled in a QoL assessment questionnaire­IBDQ-32. Subsequently, the two samples were comparatively assessed. Results: The average values of the IBDQ scores were significantly lower in 2021 compared to those recorded in 2018: 145.56 vs. 128.3 (p < 0.05). We also we found significant differences between the subscores: IBDQ1 (p = 0.043), IBDQ2 (p = 0.034), IBDQ3 (p = 0.045), IBDQ4 (p = 0.025). Conclusions: IBDQ scores were significantly lower in 2021 compared to 2018 (p < 0.05), showing that during the COVID-19 pandemic, patients with IBD had a more influenced QoL.

Anemia in Crohn's Disease-The Unseen Face of Inflammatory Bowel Disease.

Background and Objectives: Anemia is the most frequent complication of inflammatory bowel diseases. Clinically, anemia can affect important quality-of-life (QoL) components, such as exercise capacity, cognitive function, and the ability to carry out social activities. The disease activity has a significant impact on QoL, mainly due to clinical manifestations, which are more severe during the periods of disease activity. Our aim was to estimate the impact of anemia on QoL in patients with Crohn's disease. Material and Methods. We made a prospective study on 134 patients with Crohn's disease (CD) in a Romanian tertiary center. The CD diagnosis was established by colonoscopy and histopathological examination. In particular cases, additional examinations were required (small bowel capsule endoscopy, computed tomography enterography, and magnetic resonance enterography). Anemia was defined according to the World Health Organization's definition, the activity of the disease was assessed by Crohn's disease activity index (CDAI) score, and the QoL was evaluated by Inflammatory Bowel Disease Questionnaire 32 (IBDQ 32). Results: 44.8% patient had anemia, statistically related to the activity of the disease and corticoids use. We found a strong association between QoL and disease activity on all four sub-scores: patients with more severe activity had a significantly lower IBDQ (260.38 ± 116.96 vs. 163.85 ± 87.20, p = 0.001) and the presence of anemia (127.03 vs. 148.38, p = 0.001). In multiple regression analyses, both disease activity and anemia had an impact on the QoL. Conclusions: Anemia has high prevalence in the CD in northeastern region of Romania. Anemia was more common in female patients, in patients undergoing corticosteroid treatment, and in those with active disease. Both anemia and disease activity had a strong negative and independent impact on QoL.

Role of PNPLA3 in the Assessment and Monitoring of Hepatic Steatosis and Fibrosis in Patients with Chronic Hepatitis C Infection Who Achieved a Sustained Virologic Response.

Background and Objectives: Hepatic diseases are an important public health problem. All patients with chronic hepatitis C virus (HCV) infection receive treatment, regardless of hepatic fibrosis severity. However, evaluation of hepatic fibrosis and steatosis is still useful in assessing evolution, prognosis and monitoring of hepatic disease, especially after treatment with direct-acting antivirals (DAAs). The aim of this study was to assess the link between patatin-like phospholipase domain-containing 3 (PNPLA3) polymorphism and the degree of hepatic steatosis and fibrosis in patients with chronic HCV infection, as well as changes in steatosis and fibrosis three monthsafter obtaining a sustained viral response (SVR). Materials and Methods:Ourstudy included 100 patients with chronic hepatitis C (CHC) infection and compensated cirrhosis who received DAA treatment and who were evaluated using Fibromax prior to and 3 months after SVR. The influence of PNPLA3 (CC, CG, GG) genotype among these patients on the degree of post-treatment regression of steatosis and fibrosis was assessed. Results: Regression was noticed in the degree of both hepatic steatosis and hepatic fibrosis post-DAA treatment (three months after SVR). Analysis of the correlation between PNPLA3 genotype and fibrosis indicated that the average level of fibrosis (F) before DAA treatment was higher in patients with the GG genotype than in patients with the CC or CG genotype. Three months after SVR, the average level of fibrosis decreased; however, it remained significantly increased in GG subjects compared to that in CC or CG patients. The degree of hepatic steatosis before treatment was not significantly different among patients with different PNPLA3 genotypes, and no significant correlations were observed three months after SVR. Conclusions: The genetic variants of PNPLA3 influence the evolution of hepatic fibrosis. The GG subtype plays an important role in the degree of hepatic fibrosis both before and after treatment (three months after SVR)and could be a prognostic marker for assessment of post-SVR evolution.

Diagnosis of minimal hepatic encephalopathy in a tertiary care center from eastern Romania: validation of the psychometric hepatic encephalopathy score (PHES).

The psychometric hepatic encephalopathy score (PHES) is frequently used as a "gold standard" for the diagnosis of minimal hepatic encephalopathy (MHE). In Romania, there are currently no widely available tests for the detection of MHE. In this study we aimed to standardize the PHES in a healthy Romanian population and to estimate the prevalence of MHE in a group of Romanian patients with liver cirrhosis. A total of 260 healthy volunteers and 106 patients with liver cirrhosis were included in the study. The five neuropsychological tests comprising the PHES were administered to all enroled subjects. Blood samples for routine tests and serum ammonia were collected. In the healthy volunteer group age and education years were found to be predictors of all tests and gender only in two tests: digit symbol test and serial dotting test. The PHES of the healthy volunteer group was 0,43 ± 1,37 and the cut-off between normal and pathological values was set at -3 points. In the liver cirrhosis group the mean PHES was -2,44 ± 3,41, significantly lower than in the control group (p = 0,001). The estimated prevalence of MHE was 34,7 % (37 patients). In patients with cirrhosis there was a significant correlation between PHES and the severity of the liver disease according to Child-Pugh classification (r = 0,529, p = 0,001) and MELD score (r = -0,525, p = 0,001). According to our results, accurate Romanian PHES norms for the diagnosis of MHE have been developed. MHE was diagnosed in a significant proportion of Romanian patients with liver cirrhosis.

Enhancing Calprotectin's Predictive Power as a Biomarker of Endoscopic Activity in Ulcerative Colitis: A Machine Learning Use Case.

Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterized by periods of exacerbation and remission, making disease monitoring and management challenging. Endoscopy, the gold standard for assessing disease activity and severity, involves invasive procedures and is associated with patient discomfort and risks. Using machine learning (ML) to combine fecal calprotectin with other clinical or biological tests can significantly enhance the non-invasive prediction of endoscopic disease activity (EDA) in UC. Aim: To prove that by fusing fecal calprotectin with other clinical data into an ML model, the performance of the non-invasive prediction of EDA can be significantly improved. Methods: We conducted a prospective, observational, single-center study encompassing 103 patients diagnosed with UC. We employed multilayer perceptron models as the core ML algorithm for predicting EDA. For the constructed models, we utilized the varImp function from the caret library in R to assess the significance of each variable in predicting the outcome. Results: Calprotectin as a sole predictor obtained an accuracy of 70% and an area under the curve (AUC) of 0.68. Combining calprotectin with the list of selected predictors that were fed to the MLP models improved accuracy and the AUC. The accuracy of the algorithm on the test set was 85%. Similarly, the AUC increased to 0.93. This is the first study to propose the use of calprotectin as a predictor in an ML model to estimate UC endoscopic disease activity. Conclusion: The deployment of this ML model can furnish doctors and patients with valuable evaluation of endoscopic disease activity which can be highly beneficial for individuals with UC who need long-term treatment.

The Rate of Burnout Syndrome in A Tertiary Gastroenterology University Center in Romania.

BACKGROUND AND AIMS: The burnout syndrome (BOS) is commonly seen in healthcare professionals, particularly in physicians who are exposed to a high level of stress at work and has a negative impact on the medical activity. Physicians with BOS manifest a negative attitude, a reduction in compassion at work, and suboptimal patient care experiences. These all can lead to absenteeism, poor performance and more frequent medical errors. We aimed to assess the level of BOS in a tertiary gastroenterology university center in Romania. METHODS: This observational study involved 40 physicians from a tertiary gastroenterology university center. An online questionnaire assessed the presence of BOS using the Maslach Burnout Inventory. RESULTS: A total of 40 physicians responded to the questionnaire. The prevalence of overall BOS of 87.5%. In terms of high burnout, 15 doctors (37.5%) had emotional exhaustion, 10 doctors (25%) had depersonalization, and 30 doctors (80%) scored low for personal achievement. Men presented more frequently emotional exhaustion and women lower personal achievement scores, but there was no significant statistical difference. No significant relationship was found between marital status or the number of children and BOS. We identified multiple risk factors associated to BOS, the most important one being strict internal regulations. CONCLUSIONS: Physicians presented an increased risk for BOS. The high rate of BOS among physicians found in our study requires careful attention. Further studies aiming to identify other factors that contribute to BOS and to identify measures to combat this syndrome are necessary.

Novelties and Perspectives of Intestinal Ultrasound in the Personalised Management of Patients with Inflammatory Bowel Diseases-A Systematic Review.

Inflammatory bowel diseases (IBDs) affect over 4.9 million individuals worldwide. Colonoscopy (CS) is the gold-standard technique for diagnosis. The remissive-recurrent pattern of evolution raises the need for non-invasive techniques to monitor disease activity. This review aims to present the advantages of intestinal ultrasound (IUS) in managing IBDs. Our search was conducted on the PubMed, Embase, and Cochrane (CENTRAL) databases, selecting original studies comparing IUS with other imaging and invasive monitoring methods. Our search yielded 8654 results, of which 107 met the inclusion criteria. Increased bowel wall thickness (BWT) and colour Doppler signal (CDS) are discriminative for disease activity. IUS can predict disease outcomes and detect response to treatment or postoperative recurrence. Contrast-enhanced ultrasound (CEUS) and elastography help differentiate fibrotic from inflammatory stenoses. The difficult rectal assessment limits the use of IUS in ulcerative colitis (UC). Transmural healing may develop as a therapeutic target as it is associated with better outcomes. Patients are compliant with this technique, and its results correlate well with CS and other imaging methods. In conclusion, IUS proves to be essential in assessing IBD activity and treatment response, predicting outcomes and detecting complications. CEUS and elastography are researched to improve the diagnostic values of IUS.

Laboratory Data and IBDQ-Effective Predictors for the Non-Invasive Machine-Learning-Based Prediction of Endoscopic Activity in Ulcerative Colitis.

A suitable, non-invasive biomarker for assessing endoscopic disease activity (EDA) in ulcerative colitis (UC) has yet to be identified. Our study aimed to develop a cost-effective and non-invasive machine learning (ML) method that utilizes the cost-free Inflammatory Bowel Disease Questionnaire (IBDQ) score and low-cost biological predictors to estimate EDA. Four random forest (RF) and four multilayer perceptron (MLP) classifiers were proposed. The results show that the inclusion of IBDQ in the list of predictors that were fed to the models improved accuracy and the AUC for both the RF and the MLP algorithms. Moreover, the RF technique performed noticeably better than the MLP method on unseen data (the independent patient cohort). This is the first study to propose the use of IBDQ as a predictor in an ML model to estimate UC EDA. The deployment of this ML model can furnish doctors and patients with valuable insights into EDA, a highly beneficial resource for individuals with UC who need long-term treatment.

Inflammatory Bowel Disease as a Paradoxical Reaction to Anti-TNF-α Treatment-A Review.

TNF-α inhibitors (TNFis) have revolutionized the treatment of certain chronic immune-mediated diseases, being widely and successfully used in rheumatic inflammatory diseases, and have also proved their efficacy in the treatment of inflammatory bowel disease (IBD). However, among the side effects of these agents are the so-called paradoxical effects. They can be defined as the appearance or exacerbation of a pathological condition that usually responds to this class of drug while treating a patient for another condition. A wide range of paradoxical effects have been reported including dermatological, intestinal and ophthalmic conditions. The causal mechanism of occurrence may implicate an imbalance of cytokines, but is still not fully understood, and remains a matter of debate. These paradoxical reactions often show improvement on discontinuation of the medication or on switching to another TNFi, but in some cases it is a class effect that could lead to the withdrawal of all anti-TNF agents. Close monitoring of patients treated with TNFis is necessary in order to detect paradoxical reactions. In this study we focus on reviewing IBD occurrence as a paradoxical effect of TNFi therapy in patients with rheumatological diseases (rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, and juvenile idiopathic arthritis).

Evaluation of Disease Activity in Inflammatory Bowel Disease: Diagnostic Tools in the Assessment of Histological Healing.

Inflammatory bowel disease (IBD) comprises two types of chronic intestinal disorders: Crohn's disease and ulcerative colitis. In long-standing ulcerative colitis disease activity, histological persistent inflammation has been linked to an increased risk of relapse, and long-term corticosteroid use, even when endoscopic remission is reached. In Crohn's disease, the discontinuous nature of lesions and transmural inflammation have limited the standardized histological assessment. The current evidence from research proposes that besides clinical and endoscopic healing, the achievement of histological healing constitutes an endpoint to assess disease activity and remission in IBD patients concerning better long-term disease outcomes. Histological alterations may persist even in the absence of endoscopic lesions. For these reasons, new advanced techniques promise to revolutionize the field of IBD by improving the endoscopic and histologic assessment, disease characterization, and ultimately patient care, with an established role in daily practice for objective assessment of lesions. This review outlines the importance of including microscopic evaluation in IBD, highlighting the clinical benefits of a deep state of disease remission using validated diagnostic methods and scoring systems for daily clinical practice.

Ischemic Heart Disease in Patients with Inflammatory Bowel Disease: Risk Factors, Mechanisms and Prevention.

According to new research, a possible association between inflammatory bowel disease (IBD) and an increased risk of ischemic heart disease (IHD) has been demonstrated, but this concern is still debatable. The purpose of this review is to investigate the link between IHD and IBD, as well as identify further research pathways that could help develop clinical recommendations for the management of IHD risk in IBD patients. There is growing evidence suggesting that disruption of the intestinal mucosal barrier in IBD is associated with the translocation of microbial lipopolysaccharides (LPS) and other endotoxins into the bloodstream, which might induce a pro-inflammatory cytokines response that can lead to endothelial dysfunction, atherosclerosis and acute cardiovascular events. Therefore, it is considered that the long-term inflammation process in IBD patients, similar to other chronic inflammatory diseases, may lead to IHD risk. The main cardiovascular risk factors, including high blood pressure, dyslipidemia, diabetes, smoking, and obesity, should be checked in all patients with IBD, and followed by strategies to reduce and manage early aggression. IBD activity is an important risk factor for acute cardiovascular events, and optimizing therapy for IBD patients should be followed as recommended in current guidelines, especially during active flares. Large long-term prospective studies, new biomarkers and scores are warranted to an optimal management of IHD risk in IBD patients.

New onset severe ulcerative colitis following Ixekizumab therapy.

Ixekizumab is one of the three biologic agents including Secukinumab and Brodalumab that targets the Interleukin-17 (IL-17) pathway to reduce inflammation in psoriasis and ankylosing spondylitis. In this report we present the case of 42-year-old woman, who was diagnosed with psoriasis and psoriatic arthritis. One week after first administration of Ixekizumab, she developed diffuse abdominal pain, bloody diarrhea (7-8 stools/day) and fever. Following imaging (colonoscopy, computed tomography) and laboratory investigations, she was diagnosed with acute severe ulcerative colitis complicated with toxic megacolon. The medical treatment (first corticotherapy, then infliximab) has failed and the patient needed emergency colectomy. Based on the immunological mechanisms and the observation from other studies, Ixekizumab should be considered an etiology for new-onset inflammatory bowel disease.

Hereditary Hemorrhagic Telangiectasia and Arterio-Venous Malformations-From Diagnosis to Therapeutic Challenges.

Hereditary hemorrhagic telangiectasia is a rare autosomal dominant vascular disease defined by the presence of mucosal and cutaneous telangiectasia and visceral arterio-venous malformations. The latter are abnormal capillary-free direct communications between the pulmonary and systemic circulations with the following consequences: arterial hypoxemia caused by right-to-left shunts; paradoxical embolism with transient ischemic attack or stroke and brain abscess caused by the absence of the normally filtering capillary bed; and hemoptysis or hemothorax due to the rupture of the thin-walled arterio-venous malformations (particularly during pregnancy). It is frequently underdiagnosed, commonly presenting as complications from shunting through arterio-venous malformations: dyspnea, chronic bleeding, or embolism. Arterio-venous malformations are present not only in the lungs, but can also be found in the liver, central nervous system (mainly in the brain), nasal mucosa, or the gastrointestinal tract. The first choice of therapy is embolization of the afferent arteries of the arterio-venous malformations, a minimally invasive procedure with a high efficacy, a low morbidity, and low mortality. Other therapeutic modalities are surgery (resection) or stereotactic radiosurgery (using radiation). Routine screening for arterio-venous malformations is indicated in patients diagnosed with this condition and can prevent severe complications such as acute hemorrhages, brain abscesses, or strokes. Clinicians should provide a long-term follow-up for patients with arterio-venous malformations, in an effort to detect their growth or reperfusion in case of previously treated malformations. In spite of two experts' consensuses, it still possesses multiple therapeutic challenges for physicians, as several aspects regarding the screening and management of arterio-venous malformations still remain controversial. Multidisciplinary teams are especially useful in complex cases.

Extrapancreatic necrosis volume: A new tool in acute pancreatitis severity assessment?

BACKGROUND: Many scores have been suggested to assess the severity of acute pancreatitis upon onset. The extrapancreatic necrosis volume is a novel, promising score that appears to be superior to other scores investigated so far. AIM: To evaluate the discriminatory power of extrapancreatic necrosis volume to identify severe cases of acute pancreatitis. METHODS: A total of 123 patients diagnosed with acute pancreatitis at Institute of Gastroenterology and Hepatology, St Spiridon Hospital between January 1, 2017 and December 31, 2019 were analyzed retrospectively. Pancreatitis was classified according to the revised Atlanta classification (rAC) as mild, moderate, or severe. Severity was also evaluated by computed tomography and classified according to the computed tomography severity index (CTSI) and the modified CTSI (mCTSI). The results were compared with the extrapancreatic volume necrosis to establish the sensitivity and specificity of each method. RESULTS: The CTSI and mCTSI imaging scores and the extrapancreatic necrosis volume were highly correlated with the severity of pancreatitis estimated by the rAC (r = 0.926, P < 0.001 and r = 0.950, P < 0.001; r = 0.784, P < 0.001, respectively). The correlation of C-reactive protein with severity was positive but not as strong, and was not significant (r = 0.133, P = 0.154). The best predictor for the assessment of severe pancreatitis was the extrapancreatic necrosis volume [area under the curve (AUC) = 0.993; 95% confidence interval (CI): 0.981-1.005], with a 99.5% sensitivity and 99.0% specificity at a cutoff value of 167 mL, followed by the mCTSI 2007 score (AUC = 0.972; 95%CI: 0.946-0.999), with a 98.0% sensitivity and 96.5% specificity, and the CTSI 1990 score (AUC = 0.969; 95%CI: 0.941-0.998), with a 97.0% sensitivity and 95.0% specificity. CONCLUSION: Radiological severity scores correlate strongly and positively with disease activity. Extrapancreatic necrosis volume shows the best diagnostic accuracy for severe cases.

The specialized educational and psychological counseling in inflammatory bowel disease patients - a target or a challenge?

BACKGROUND/AIMS: Stress, in its various forms, plays an important role in the development and evolution of inflammatory bowel disease (IBD). For patients with IBD, the evidence related to the effects of various types of psychological therapies remains inconclusive. This study aimed to evaluate whether cognitive behavioral therapy, in combination with educational counseling, influenced disease activity and quality of life (QoL) among patients with IBD. MATERIALS AND METHODS: We conducted a randomized controlled trial with 60 patients diagnosed with IBD. All patients completed the IBD questionnaire-32 (IBDQ-32) and the Big Five Inventory. Group A (experimental group) received specialized educational and psychological counseling (SEPC), and group B (control group) was treated according to the current medical practice. All patients were reassessed after 12 months. RESULTS: After the SEPC, there was no improvement in disease activity as estimated by fecal calprotectin levels. However, the QoL of patients in group A was significantly improved. The highest mean difference between the initial and final IBDQ scores was found among patients whose main personality trait was openness to experience (48.58±28.80), and the lowest mean difference between these 2 scores was found among patients whose main personality trait was closedness to experience (3.33±2.97, p=0.009). CONCLUSION: Although there was no improvement in disease activity after the SEPC, this therapy improved patients' QoL in terms of both emotional and social functions, especially among patients whose dominant personality trait was openness to experience or neuroticism.

Looking beyond gut inflammation in inflammatory bowel disease.

Patients diagnosed with inflammatory bowel disease (IBD) often develop one or more extraintestinal manifestations (EIM). We performed a prospective study that included 517 patients with IBD (Crohn's disease - CD, ulcerative colitis - UC or undifferentiated colitis - CN) diagnosed between 1975 and 2016 in the Northeastern region of Romania. The patients were extracted from the national database (IBD Prospect). UC cases predominated compared to CD cases (n=368 vs. n=135). Only 10 patients were diagnosed with CN. In the study group, 51 cases with IBD and EIM were identified, having a prevalence of 9.9%. Musculoskeletal manifestations were the most common EIM. Peripheral involvement - arthritis (n=26, 68.42%) predominated, followed by axial damage - sacroiliitis/ankylosing spondylitis (SI∕AS) (n=12, 31.58%) (p=0.001). Patients with CD had a 3.48-fold greater risk of developing joint manifestations [p<0.001, odds ratio (OR)=3.478, 95% confidence interval (CI) 1.779-6.801]. In both CD and UC patients, arthritis cases were the most frequent observed (68.42% vs. 31.58%). Patients with CD had a 5-fold higher risk of developing arthritis (p<0.001, OR=5.009, 95% CI 2.21-11.34). Neither CD, nor UC patients, had a confirmed risk of developing SI∕AS (p=0.468, OR=1.565, 95% CI 0.463-5.293 for CD) (p=0.586, OR=0.714, 95% CI 0.211-2.413 for UC). Cases of arthritis and CD (n=16) mainly correlated with the colonic localization of inflammation (n=7, p=0.723) followed by ileo-colonic form of CD (n=7, p=0.321). Patients with arthritis and UC (n=10) initially correlated with pancolitis (n=5, p=0.072, OR=3.023, 95% CI 0.855-10.69) then with proctitis (n=3, p=0.392) and left-sided colitis (n=2, p=0.024, OR=0.196, 95% CI 0.041-0.938).

Bidirectional Relationship between Gastric Emptying and Plasma Glucose Control in Normoglycemic Individuals and Diabetic Patients.

Gastric emptying and glycemic control pathways are closely interrelated processes. Gastric chyme is transferred into the duodenum with velocities depending on its solid or liquid state, as well as on its caloric and nutritional composition. Once nutrients enter the intestine, the secretion of incretins (hormonal products of intestinal cells) is stimulated. Among incretins, glucagon-like peptide-1 (GLP-1) has multiple glycemic-regulatory effects that include delayed gastric emptying, thus triggering a feedback loop lowering postprandial serum glucose levels. Glycemic values also influence gastric emptying; hyperglycemia slows it down, and hypoglycemia accelerates it, both limiting glycemic fluctuations. Disordered gastric emptying in diabetes mellitus is understood today as a complex pathophysiological condition, with both irreversible and reversible components and high intra- and interindividual variability of time span and clinical features. While limited delays may be useful for reducing postprandial hyperglycemias, severely hindered gastric emptying may be associated with higher glycemic variability and worsened long-term glycemic control. Therapeutic approaches for both gastric emptying and glycemic control include dietary modifications of meal structure or content and drugs acting as GLP-1 receptor agonists. In the foreseeable future, we will probably witness a wider range of dietary interventions and more incretin-based medications used for restoring both gastric emptying and glycemic levels to nearly physiological levels.

A rapid test for assessing disease activity in ulcerative colitis.

BACKGROUND/AIMS: Direct assessment by endoscopic examination has become a "gold standard" in monitoring patients with ulcerative colitis. However, it is an invasive method, with risks and discomfort for the patients. The aim is therefore to identify a less invasive method of assessing ulcerative colitis activity compared to colonoscopy. MATERIALS AND METHODS: A prospective study was conducted among 103 patients with ulcerative colitis. Calprotectin was measured by a semi-quantitative rapid test. For each patient, a complete blood count was performed; liver and kidney functions, glycaemia, serum proteins, and inflammatory markers were also evaluated. RESULTS: The Mayo score showed direct correlations with fecal calprotectin, C-reactive protein, and the erythrocyte sedimentation rate (p<0.05) and indirect correlations with hemoglobin (p=0.139). The sensitivity and specificity of calprotectin were 98.0% and 76.7%, respectively. Subsequently, combined analysis of the markers' sensitivity/specificity was conducted. CONCLUSION: The semi-quantitative rapid test proved to be a good predictor for differentiating the endoscopic active disease from the inactive one. The individual use of fecal calprotectin presents the highest sensitivity in determining the endoscopic activity. Nevertheless, in monitoring patients, combined determination of the three inflammatory markers studied [C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), calprotectin] is more useful in reducing unnecessary colonoscopies.

SCORING IN ACUTE PANCREATITIS: WHEN IMAGING IS APPROPRIATE?.

Acute pancreatitis (AP) is a frequent presentation to the emergency departments with a rising incidence and a great variability in clinical severity and outcome. The aim of this review is to offer a succinct presentation on acute pancreatitis scoring systems and the use of different imaging methods in severity prediction: Ranson criteria, Glasgow criteria, Hong Kong Score, Acute Physiology and Chronic Health Evaluation II (APACHE II), computed tomography scoring systems, Bedside Index of Severity in Acute Pancreatitis (BISAP) score, Panc 3, Japanese Severity Score (JSS), Harmless Acute Pancreatitis Score (HAPS), Pancreatitis Outcome Prediction (POP), Sequential Organ Failure Assessment (SOFA). This article also describes the Revised Atlanta Classification of AP (2012) and the correlation with computed tomography.
