Celiac Disease and Autoimmune Diseases in a Pediatric Population in Morocco: A Cross-Sectional Study.

INTRODUCTION: Celiac disease (CD) is defined as an autoimmune disease (AD) caused by gluten ingestion in genetically sensitive individuals. Several publications have demonstrated the increased risk of AD in patients with CD, both adults and children, which requires systematic research. Our study aimed to determine the prevalence of AD in 60 patients diagnosed with CD and to highlight risk factors that may contribute to the emergence of AD. MATERIALS AND METHODS: We collected medical data from all CD patients under 16 years of age who also had AD. Our study was conducted in the Gastroenterology-Hepatology and Pediatric Nutrition Unit of the Pediatrics Department of the Mohamed VI Hospital and University Center in Oujda, Morocco, during a seven-year period between January 2017 and January 2024. RESULTS: We studied 60 patients with CD in our study. Eight patients (13%) had an associated AD. Their average age was eight years, with extremes varying between two and 15 years. AD was diagnosed before CD in six cases (75%), in parallel with CD in one patient (12.5%), while in only one case, it was diagnosed after CD (12.5%). All our patients had a single AD associated with CD. These ADs were mainly type 1 diabetes in seven cases and autoimmune thyroiditis in only one case. All our patients followed a gluten-free diet in addition to specific treatment for associated AD. Nevertheless, despite regular medical follow-up and targeted dietary advice for the management of CD and associated AD, three patients encountered difficulties in following the recommended diet. CONCLUSION: Younger patients with CD have an increased risk of hypothyroidism and insulin-dependent diabetes. These data necessitate improved surveillance to discover these illnesses as early as possible in order to optimize management and reduce related consequences.

In Vitro Protective Effect of Pea-Derived Peptides (PPs) via the Keap1/Nrf2 Signaling Pathway on Alpha-Gliadin-Sensitizing Peptide Induced Cacao-2 Cells.

SCOPE: Celiac disease (CD) is an allergic intestinal disease caused mainly by gliadin in wheat, which is widespread in the population and currently lacks effective treatment. α-Gliadin peptides cause cellular damage by substantially increasing cellular reactive oxygen species (ROS) levels. METHODS AND RESULTS: This study investigates the protective effect of 11 pea-derived peptides (PPs) on ɑ-gliadin peptide (P31-43) treated Caco-2 cells. Results show that cells treated with PP2, PP5, and PP6 peptides significantly reduce the cell mortality caused by P31-43. Three PPs significantly reduce the P31-43-induced decrease in ROS levels to control levels, and there is no difference between them and the vitamin C (Vc) group. The results in terms of antioxidant-related enzymes show that PPs significantly decrease superoxide dismutase activity (SOD), glutathione reductases (GR), and glutathione (GSH)/oxidized glutathione (GSSG) levels, thus significantly enhancing the antioxidant level of cells. By studying the key proteins of the Kelch-like ECH-associated protein 1 (Keap1)/NF-E2-related factor 2 (Nrf2) pathway, it is found that PPs activate the Keap1/Nrf2 signaling pathway. CONCLUSION: The study finds that peptides from peas can effectively alleviate ɑ-gliadin peptide-induced cell damage. The discovery of these food-derived peptides provides novel potential solutions for the prevention and treatment of CD.

Post-surgical Median Arcuate Ligament Syndrome (MALS) Symptom Exacerbation Treated With Osteopathic Manipulative Treatment (OMT): A Case Report.

Median arcuate ligament syndrome (MALS, also known as celiac artery compression syndrome, celiac axis syndrome, celiac trunk compression syndrome, Dunbar syndrome, or Harjola-Marable syndrome) is a rare condition characterized by abdominal pain attributed to the compression of the celiac artery and celiac ganglia by the median arcuate ligament. Pain can occur post-prandially and may be accompanied by weight loss, nausea, or vomiting. Following angiographic diagnosis, current definitive treatment may include open or laparoscopic decompression surgery with celiac ganglion removal (if affected), which has been found to provide relief. In this case report, we outline a young female patient with a MALS diagnosis and subsequent surgery, but whose pain recurred in various stress-related instances even after surgical intervention. After a particular pain episode, osteopathic manipulative treatment (OMT) was applied, with a focus on restoring autonomic balance through the use of various gentle osteopathic treatment techniques. A significant reduction in pain was reported post-treatment, followed by complete pain resolution, indicating a great benefit to the incorporation of OMT into the treatment plan of MALS patients in future osteopathic practice.

The Frequently Used Industrial Food Process Additive, Microbial Transglutaminase: Boon or Bane.

Microbial transglutaminase (mTG) is a frequently consumed processed food additive, and use of its cross-linked complexes is expanding rapidly. It was designated as a processing aid and was granted the generally recognized as safe (GRAS) classification decades ago, thus avoiding thorough assessment according to current criteria of toxicity and public health safety. In contrast to the manufacturer's declarations and claims, mTG and/or its transamidated complexes are proinflammatory, immunogenic, allergenic, pathogenic, and potentially toxic, hence raising concerns for public health. Being a member of the transglutaminase family and functionally imitating the tissue transglutaminase, mTG was recently identified as a potential inducer of celiac disease. Microbial transglutaminase and its docked complexes have numerous detrimental effects. Those harmful aspects are denied by the manufacturers, who claim the enzyme is deactivated when heated or by gastric acidity, and that its covalently linked isopeptide bonds are safe. The present narrative review describes the potential side effects of mTG, highlighting its thermostability and activity over a broad pH range, thus, challenging the manufacturers' and distributers' safety claims. The national food regulatory authorities and the scientific community are urged to reevaluate mTG's GRAS status, prioritizing public health protection against the possible risks associated with this enzyme and its health-damaging consequences.

Rapid diagnosis of celiac disease based on plasma Raman spectroscopy combined with deep learning.

Celiac Disease (CD) is a primary malabsorption syndrome resulting from the interplay of genetic, immune, and dietary factors. CD negatively impacts daily activities and may lead to conditions such as osteoporosis, malignancies in the small intestine, ulcerative jejunitis, and enteritis, ultimately causing severe malnutrition. Therefore, an effective and rapid differentiation between healthy individuals and those with celiac disease is crucial for early diagnosis and treatment. This study utilizes Raman spectroscopy combined with deep learning models to achieve a non-invasive, rapid, and accurate diagnostic method for celiac disease and healthy controls. A total of 59 plasma samples, comprising 29 celiac disease cases and 30 healthy controls, were collected for experimental purposes. Convolutional Neural Network (CNN), Multi-Scale Convolutional Neural Network (MCNN), Residual Network (ResNet), and Deep Residual Shrinkage Network (DRSN) classification models were employed. The accuracy rates for these models were found to be 86.67%, 90.76%, 86.67% and 95.00%, respectively. Comparative validation results revealed that the DRSN model exhibited the best performance, with an AUC value and accuracy of 97.60% and 95%, respectively. This confirms the superiority of Raman spectroscopy combined with deep learning in the diagnosis of celiac disease.

[Beyond hypercoagulability in celiac disease]. / Más allá de la hipercoagulabilidad en la enfermedad celíaca.

In celiac disease (CD) there is a state of hypercoagulability and multiple factors have been found that may be involved. Cases of association of CD and antiphospholipid síndrome (APS) have been described and several observational studies have found an increase in antiphospolipid antibodies (AAF) in patients with CD, so both entities may be interrelated, increasing the risk of thrombotic events. A descriptive case of a patient who is simultaneusly diagnosed with CD and APS is presented.

Para-aortic lymph node dissection with or without nerve-sparing in gynecological malignancies.

OBJECTIVE: Para-aortic lymph node dissection (PALND) is a widely used treatment that causes many complications. This study is to evaluate the efficacy and safety of nerve-sparing para-aortic lymph node dissection (NSPALND) by comparing it with conventional PALND in gynecological malignancies and to prove whether locating the superior hypogastric plexus (SHP) can help reveal the para-aortic nerves. METHODS: This is a retrospective study of the patients who underwent para-aortic lymphadenectomy from January 2020 to December 2022 at Zhejiang Cancer Hospital. All of them were divided into NSPALND and PALND groups according to whether or not nerve-sparing was performed. The surgical, functional and oncological outcomes were evaluated. RESULTS: There were 43 patients enrolled, of which, 20 patients underwent NSPALND and 23 patients underwent PALND. The para-aortic nerves were successfully revealed by locating the SHP in all 20 cases of NSPALND. The post-operative anal exhaust time in the NSPALND group was significantly shorter than that in the PALND group (2.5 vs. 4 days, p=0.006), and the incidence of acute intestinal obstruction in the NSPALND group was significantly lower than that in the PALND group (10% vs. 39%, p=0.029). There was no difference between the two groups in terms of catheterization duration, urinary retention, dysuria, as well as the number of lymph nodes removed and the para-aortic recurrence rate. CONCLUSION: NSPALND can significantly reduce the rate of acute intestinal obstruction and improve post-operative intestinal function. Locating the SHP and using it as an anatomical landmark to reveal the para-aortic nerves is feasible. Its exact clinical value needs to be further studied.

Decreasing incidence of celiac disease in Southern Sweden.

BACKGROUND: The incidence of celiac disease (CD) has increased rapidly in the late 20th and early 21st centuries, but there are recent reports of rates levelling off in countries with a high prevalence. The aim of this study was to investigate current trends in CD in southern Sweden. PATIENTS AND METHODS: Children and adults diagnosed with CD by biopsy or serology in the region of Skåne, southern Sweden, from 2010-2022 were included. The home address was identified through registers to analyze temporal and geographical trends. RESULTS: A total of 3218 CD-patients were identified (52.2% children), the vast majority detected in clinical care but a few children by screening studies. The age-standardized incidence rate was 18.6 cases/105. The incidence decreased at a rate of -0.75 cases/105 (95% CI -1.14 to -0.35, p 0.002). The incidence among girls under 18 years almost halved throughout the study period, decreasing by -2.94 cases/105 (95% CI -4.59 to -1.29, p 0.002), while there only were small changes among men. The most common age of onset was 3-9 years. CD incidence varied by place of living and was more common in small towns than urban or rural areas. CONCLUSIONS: The incidence of CD in southern Sweden is decreasing, primarily in children and women who traditionally have had the highest risk of CD. CD was diagnosed most frequently in children 3-9 years old. There were regional variations in incidence. CD was most common in small towns, pointing to the importance of environmental factors in CD etiology.

Determination of the Frequency of Celiac Disease in Patients Presenting With Chronic Diarrhea.

INTRODUCTION: Celiac disease (CD) is a chronic inflammatory disorder affecting mainly the digestive system and accounts for more than 50% of adult cases presenting to the gastrointestinal clinic with chronic diarrhea. Therefore, in our study, we aimed to determine the prevalence of CD in patients presenting with chronic diarrhea at the gastroenterology outpatient department of Jinnah Hospital, Lahore. METHODS: This cross-sectional study was conducted from December 9, 2021, to June 8, 2022, and included 140 patients aged 18 to 50 years with chronic diarrhea. Exclusion criteria were lack of informed consent and history of abdominal trauma or surgery. Data collected included age, gender, family history of CD, and clinical symptoms. Diagnostic measures involved serum tissue transglutaminase antibody IgA and IgG levels, endoscopy, and duodenal biopsy. Statistical analysis was performed using SPSS version 23 (IBM Corp, Armonk, NY), with a p-value of ≤0.05 considered significant. RESULTS: Among the 140 patients, 80 (57.14%) were males, with a mean age of 21 ± 4.35 years. Common symptoms included weight loss (73.5%), abdominal pain (20.7%), and stunted growth (5.7%). A family history of CD was reported in 14.29% of patients. Endoscopy findings included fissuring of the duodenal mucosa (77.9%), decreased height of duodenal folds (15.7%), and nodularity (6.4%). Histopathological examination revealed Marsh III b (65%), Marsh III c (21.4%), and Marsh III a (9.3%). CD was diagnosed in 23.57% of patients. Significant associations were found between CD and female gender, family history of CD, weight loss, stunted growth, and Marsh III c histopathology. CONCLUSION: CD was diagnosed in 23.57% of patients with chronic diarrhea. It was more prevalent in females and those with a family history of CD. These findings emphasize the need for considering CD in the differential diagnosis of chronic diarrhea to ensure early detection and management.

Aspergillus niger prolyl endopeptidase in celiac disease.

We comment here on the article by Stefanolo et al entitled "Effect of Aspergillus niger prolyl endopeptidase in patients with celiac disease on a long-term gluten-free diet", published in the World Journal of Gastroenterology. Celiac disease is a well-recognized systemic autoimmune disorder. In genetically susceptible people, the most evident damage is located in the small intestine, and is caused and worsened by the ingestion of gluten. For that reason, celiac patients adopt a gluten-free diet (GFD), but it has some limitations, and it does not prevent re-exposure to gluten. Research aims to develop adjuvant therapies, and one of the most studied alternatives is supplementation with Aspergillus niger prolyl endopeptidase protease (AN-PEP), which is able to degrade gluten in the stomach, reducing its concentration in the small intestine. The study found a high adherence to the GFD, but did not address AN-PEP as a gluten immunogenic peptide reducer, as it was only tested in patients following a GFD and not in gluten-exposing conditions. This study opens up new research perspectives in this area and shows that further study is needed to clarify the points that are still in doubt.

Laparoscopic Treatment of a Symptomatic Young Woman With Median Arcuate Ligament Syndrome.

Median arcuate ligament syndrome (MALS), also known as Dunbar syndrome, celiac axis syndrome, or celiac artery compression syndrome, is caused by a band of tissue called the median arcuate ligament that compresses the celiac artery and sometimes the celiac plexus too. MALS does not always cause symptoms, but when symptoms occur, surgery is the treatment of choice. This case report focuses on the case of a 27-year-old woman presenting with postprandial episodes of abdominal pain and vomiting accompanied by loss of weight, which was found to be MALS.

Clinical Outcomes of Celiac Artery Coverage vs Preservation During Thoracic Endovascular Aortic Repair.

BACKGROUND: Adequate proximal and distal seal zones are necessary for successful Thoracic Endovascular Aortic Repair (TEVAR). Often, the achievement of an adequate distal seal zone requires celiac artery (CA) coverage by endograft with or without preservation of CA blood flow. The outcomes of CA coverage without its flow preservation were studied only in small case series. This study aims to determine the difference in outcomes between CA coverage with vs without preservation of CA blood flow during TEVAR using a multi-institutional national database. METHODS: Vascular Quality Initiative (VQI) was reviewed for all TEVAR patients distally landing in Zone 6. The cohort was divided into TEVAR with vs without CA flow preservation. Demographic, clinical, and perioperative characteristics, as well as post-operative mortality, morbidities, and complications, were compared between the groups. Univariate and multivariate regression analyses were performed. RESULTS: Out of 25,549 reviewed patients, 772 had a distal landing in zone 6, 212 of which (27.5%) had TEVAR without CA flow preservation, whereas 560 (72.5%) underwent TEVAR with CA flow preservation. Indications for TEVAR were: aneurysm in 431 (55.8%), dissection in 247 (32.0%), or other in 94 (12.2%) cases. Patients who underwent TEVAR without CA flow preservation had statistically significantly higher rates of 30-day mortality (11.3% vs 5.9%, p=0.010), 30-day disease/treatment-related mortality (8.0% vs 4.3%, p=0.039), as well as a tendency of increased intestinal ischemia requiring intervention (1.9% vs 0.5%, p=0.077). After adjusting for potential confounders, CA coverage without flow preservation was associated with more than a two-fold increase in the overall 30-day mortality (OR: 2.83, 95%CI: 1.35-5.92, p=0.006) and 30-day disease/treatment-related mortality (OR: 2.72, 95%CI: 1.11-6.72, p=0.029). In a sub-group analysis based on disease pathology, these results persisted only in the aneurysm group (30-day mortality (OR: 2.36, 95%CI: 1.01-5.48, p=0.047), 30-day disease/treatment-related mortality (OR: 2.88, 95%CI: 1.08-7.67, p=0.034)), whereas there was no significant association between CA flow preservation status and the endpoints in the dissection subgroup (30-day mortality (OR: 1.16, 95%CI: 0.22-6.05, p=0.856), 30-day disease/treatment-related mortality (OR: 0.90, 95%CI: 0.16-5.19, p=0.911)). CONCLUSIONS: CA coverage during TEVAR without preservation of its blood flow is associated with significantly higher mortality in patients with aortic aneurysm, but not dissection. In patients with aortic aneurysm CA flow should be preserved during TEVAR whenever feasible, whereas in patients with dissection, it may be safe to cover CA without preservation of its flow. Prospective studies should be done to confirm these findings and compare the open vs endovascular revascularization techniques on outcomes.

Clinical characteristics and impact of pseudo-lumen blood flow on long-term vessel dilatation in spontaneous isolated dissection of superior mesenteric/celiac artery.

This study aimed to identify the clinical characteristics associated with spontaneous isolated dissection of superior mesenteric artery/celiac artery (SIDSMA/SIDCA). This observational study, conducted at Toranomon Hospital, Japan between 2009 and 2020, analyzed consecutive SIDSMA/SIDCA cases based on radiology data. The study compared clinical characteristics between symptomatic and asymptomatic patients with SIDSMA/SIDCA and investigated factors related to future vessel dilatation. Among 57 cases (44 SIDSMA, 17 SIDCA, and 4 both), the majority were male (87.7%), nearly half having hypertension (43.9%) and smokers (48.9%). Of those, 17 cases (29.8%) were symptomatic; abdominal pain (94.1%), back pain (23.5%), nausea (17.6%) and fever (5.9%). The symptomatic group was younger (52.6 ± 9.4 versus 67.2 ± 7.9 years, P < 0.001), had higher systolic and mean blood pressure (142.6 ± 20.0 versus 129.5 ± 16.5 mmHg, P = 0.017; 96.1 ± 14.6 versus 88.2 ± 17.7 mmHg, P = 0.038), a higher white blood cell count (9975 ± 5032 versus 6268 ± 1991 /µL, P = 0.012), and a higher LDL cholesterol level at diagnosis (129.7 ± 21.7 versus 87.2 ± 25.6 mg/dL, P = 0.002) than the asymptomatic group. The factors associated with future vessel dilatation included the presence of pseudo-lumen flow in the dissection vessel (73.9% versus 41.4%, p = 0.019) and a larger vessel diameter (13.5 ± 2.4 mm versus 11.5 ± 2.1 mm, p = 0.005) at diagnosis after multiple adjustments, pseudo-lumen flow was a predictor of future vessel dilatation (odds ratio, 4.80; 95% confidence interval, 1.11-20.75; p = 0.036). The study revealed that only 30% of SIDSMA/SIDCA cases were symptomatic. Symptomatic cases were generally younger and exhibited higher blood pressure and elevated white blood cell counts. These findings offer valuable insights for the acute diagnosis of SIDSMA/SIDCA.

Clinical presentation of celiac disease in adult patients: current real-life experience.

BACKGROUND AND AIMS: The clinical presentation of celiac disease (CD) has changed over time with more patients presenting with non-classical symptoms, extra-intestinal manifestations (EIM) or no symptoms. We aimed to investigate the main symptoms/signs leading to the diagnosis of CD in adult patients. As secondary end-point, we evaluated the outcome of gastrointestinal (GI) symptoms following gluten-free diet (GFD). METHODS: All consecutive CD adult patients referring to our University Hospital from September 2022 to February 2024 were included. Clinical data were retrospectively evaluated. RESULTS: 134 patients, 104 females/30 males, median age at diagnosis 35 years, were included. 79 patients reported GI symptoms (i.e., diarrhea, abdominal bloating, dyspepsia) as the main symptom leading to CD diagnosis. In 40 patients, the leading symptom/sign was an EIM (i.e., iron deficiency anemia, infertility/miscarriages, dermatitis, osteoporosis, elevated transaminase levels). Fifteen patients were asymptomatic, being diagnosed because of a positive family history or concomitant autoimmune hypothyroidism. Of the 79 patients reporting GI symptoms, 20 did not experience complete resolution with the GFD. Among the 17 patients who reported a strict adherence to GFD (vs 1 patient with low-adherence, 2 non-compliant), lactose intolerance and irritable bowel syndrome overlap were diagnosed in 2 and 15 patients, respectively. CONCLUSION: GI manifestations remain the main symptoms at presentation of CD, however clinicians should be aware of the EIM of CD and the association with other autoimmune disorders. In non-responsive CD patients, an overlap with functional disorders might be considered.

EUS-guided radiofrequency ablation of solid pancreatic lesions: An updated review.

Recent years have brought to light newly developed therapeutic modalities for the treatment of premalignant and malignant pancreatic lesions. The role of EUS-guided radiofrequency ablation (EUS-RFA) as a treatment modality for malignant pancreatic lesions is still under evaluation. Several animal studies and human studies have demonstrated the safety and efficacy of EUS-RFA in the management of premalignant and malignant pancreatic lesions. EUS-RFA therapy can potentially ablate these lesions safely and with minimally invasive techniques. In this article, we provide an updated review of the application of EUS-RFA of pancreatic lesions. We also review the clinical efficacy and safety of this technique and future directions.

Clinical efficacy of EUS-guided celiac plexus neurolysis versus EUS-guided celiac ganglion irradiation with iodine-125 seeds for pain relief in advanced pancreatic cancer: A long-term retrospective study.

Background and Objective: To compare the efficacy of EUS-guided celiac plexus neurolysis (CPN) and celiac plexus irradiation with iodine-125 (125I) seeds with absolute ethanol for relieving pain in patients with advanced pancreatic cancer. Methods: We retrospectively analyzed data of 81 patients with advanced pancreatic cancer who underwent EUS-CPN or EUS-125I implantation between January 2017 and December 2020. Postoperative pain was assessed using visual analog scale (VAS) scores; self-assessments of quality of life and the median survival time were compared between the 2 groups. Results: EUS-CPN and 125I implantation were performed in 43 and 38 patients, respectively. Postoperative VAS scores were significantly lower than the preoperative levels in both groups. One week after the operation, 26 patients (60.5%) in the EUS-CPN group achieved partial pain relief, whereas no patients in the EUS-125I seed group experienced pain relief. However, after 4 weeks postoperatively, VAS scores had decreased, and the rate of partial pain relief was higher for EUS-125I seeds than for EUS-CPN. Self-assessments of quality of life were similar in both groups during the first 1 month after the procedure. Conclusions: Both EUS-CPN and EUS-125I seeds can safely and effectively relieve pain in patients with advanced pancreatic cancer. Although EUS-125I seeds take additional time to show effects, the extent and duration of pain relief are better compared with CPN, and interestingly, the median survival time was different.

Structural and mechanistic analysis of Ca2+-dependent regulation of transglutaminase 2 activity using a Ca2+-bound intermediate state.

Mammalian transglutaminases, a family of Ca2+-dependent proteins, are implicated in a variety of diseases. For example, celiac disease (CeD) is an autoimmune disorder whose pathogenesis requires transglutaminase 2 (TG2) to deamidate select glutamine residues in diet-derived gluten peptides. Deamidation involves the formation of transient γ-glutamyl thioester intermediates. Recent studies have revealed that in addition to the deamidated gluten peptides themselves, their corresponding thioester intermediates are also pathogenically relevant. A mechanistic understanding of this relevance is hindered by the absence of any structure of Ca2+-bound TG2. We report the X-ray crystallographic structure of human TG2 bound to an inhibitory gluten peptidomimetic and two Ca2+ ions in sites previously designated as S1 and S3. Together with additional structure-guided experiments, this structure provides a mechanistic explanation for how S1 regulates formation of an inhibitory disulfide bond in TG2, while also establishing that S3 is essential for γ-glutamyl thioester formation. Furthermore, our crystallographic findings and associated analyses have revealed that i) two interacting residues, H305 and E363, play a critical role in resolving the thioester intermediate into an isopeptide bond (transamidation) but not in thioester hydrolysis (deamidation); and ii) residues N333 and K176 stabilize preferred TG2 substrates and inhibitors via hydrogen bonding to nonreactive backbone atoms. Overall, the intermediate-state conformer of TG2 reported here represents a superior model to previously characterized conformers for both transition states of the TG2-catalyzed reaction.

Distribution pattern of the celiac, cranial mesenteric, and caudal mesenteric arteries to the gastrointestinal tract in the common marmoset (Callithrix jacchus).

Gastrointestinal diseases pose problems to captive common marmosets. Therefore, knowledge of the anatomy of the arterial supply to the gastrointestinal tract is an important prerequisite for implementing appropriate veterinary care. The common marmoset's intestinal tract has a well-developed cecum specialized for the fermentative digestion of tree gums. This specialized gastrointestinal tract may have a unique pattern of arterial distribution. This study aimed to elucidate the species-specific gastrointestinal tract arterial anatomy of the common marmoset. We traced the celiac, cranial mesenteric, and caudal mesenteric arteries in six male and nine female common marmosets using the latex injection method. We found that the celiac artery gave rise to the left gastric, common hepatic, splenic, and caudal pancreaticoduodenal arteries. In addition to these arteries, the celiac artery gave origin to the middle colic or jejunal arteries in seven or one cases, respectively. The branches of the cranial mesenteric artery consisted of 3-6 arteries, including the middle colic, caudal pancreaticoduodenal, jejunal, right colic, ileocolic, and ileal arteries, as well as a common trunk of the ventral cecal and ileal branches, and the dorsal cecal and colic branches. In four cases, the cranial mesenteric artery gave rise to the jejunal, ileocolic, and ileal arteries. In one of the 13 cases, the celiac and cranial mesenteric arteries formed a common trunk. The caudal mesenteric artery branched into the left colic, sigmoid, and cranial rectal arteries in all the cases. These findings provide an anatomical basis for gastrointestinal veterinary care of common marmosets.

Gastric band removal: mind the arterial anastomoses!

Bariatric surgery may sometimes be challenging and may lead to severe complications. Surgical re-intervention in such cases is not the preferred option due to co-morbidities. When severe bleeding occurs, embolization of the lacerated vessels is the preferred minimal invasive management option and needs to be available if possible. We would like to report a case of young patient who underwent severe bleeding after migration of a gastric band. The patient was successfully embolized and the band was removed. However, on the second post-operative day, the patient complained again for acute abdominal pain and turned haemodynamically unstable. Fresh blood was aspirated from the surgical drain. A new emergency CT scan was performed and a new large pseudoaneurysm was revealed taking origin from the left gastric artery. The second bleeding occurred due to an anastomotic communication and was also successfully embolized. The main take home messages are that bariatric surgery may lead to several complications including bleeding, gastric band may cause vessel erosion but also offer a tamponade effect, endovascular embolization of the lacerated vessels is the preferred management and pseudoaneurysms arising in hepato-splenic or gastroduodenal arteries should be treated with the sandwich embolization technique.

The Impacts of Inflammatory and Autoimmune Conditions on the Endometrium and Reproductive Outcomes.

Background: A healthy pregnancy begins with an adequate endometrial state, even before the arrival of a blastocyst. Proper endometrial priming and the development of a tolerogenic decidua are key steps in creating the perfect environment for implantation and pregnancy. In these processes, the involvement of the maternal immune system seems to be of great relevance, modulating the different decidual immune populations to prepare the endometrium for a potential pregnancy. However, certain local pathologies of an inflammatory and autoimmune nature appear to have a direct impact on these phenomena, thus altering patients' reproductive outcomes. Methods: This literature review analyzes original articles, reviews, systematic reviews, and meta-analyses published between 1990 and 2024, concerning the impact of different inflammatory and autoimmune conditions on endometrial status and fertility. The included papers were obtained from Medline (Pubmed) and the Cochrane library. Results: There is evidence that endometriosis, adenomyosis, and chronic endometritis, through the promotion of a chronic inflammatory environment, are capable of altering endometrial immune populations, and, thus, processes essential for early pregnancy. Among other effects, these conditions have been linked to impaired decidualization, alterations in progesterone responsiveness, and hindered placentation. Similarly, antiphospholipid syndrome (APS), thyroid dysfunction, diabetes, and other pathologies related to glucose and gluten metabolism, due to their autoimmune nature, also appear to have a local impact on the uterine environment, affecting reproductive success through different mechanisms, including altered hormonal response and, again, impaired decidualization. Conclusions: The management of inflammatory and autoimmune diseases in assisted reproduction patients is gaining importance due to their direct impact on the endometrium. It is necessary to follow current expert recommendations and established therapeutic approaches in order to improve patients' prospects, ranging from antibiotic treatment in chronic endometritis to heparin and aspirin in APS, as well as hormonal treatments for endometriosis/adenomyosis or a gluten-free diet in celiac disease. All of them and the rest of the therapeutic perspectives, both current and under investigation, are presented throughout this work, assessing the possible improvements for reproductive outcomes.
