Two distinct colonic CD14 subsets characterized by single-cell RNA profiling in Crohn's disease.

Inflammatory bowel diseases are associated with dysregulated immune responses in the intestinal tissue. Four molecularly identified macrophage subsets control immune homeostasis in healthy gut. However, the specific roles and transcriptomic profiles of the phenotypically heterogeneous CD14 macrophage-like population in inflamed gut remain to be investigated in Crohn's disease (CD).

Recruitment of activated neutrophils correlates with disease severity in adult Crohn's disease.

Neutrophils are detected in inflamed colon in Crohn's disease (CD). However, whether the frequency and/or activation of circulating or gut tissue neutrophils correlate with endoscopic severity remains to be investigated. A cohort of 73 CD patients was prospectively enrolled according to endoscopic severity and treatment history.

Patients With Inflammatory Bowel Disease Are Unaware of the Impact of Smoking on Their Disease.

Backgound: Tobacco is one of the most significant risk factors for inflammatory bowel disease (IBD).

Goals: The main objective was to assess the knowledge of patients with IBD regarding the effects of tobacco on their disease. Secondary objectives were to determine the source of their knowledge, the influence of their knowledge on their intent to quit smoking, and the association between patients' characteristics and their knowledge.

Prevention of infection caused by immunosuppressive drugs in gastroenterology.

Immunosuppressive therapy is frequently used to treat gastrointestinal diseases such as inflammatory bowel disease, autoimmune hepatitis, IgG4-related disease (autoimmune pancreatitis and sclerosing cholangitis) and in the post-transplantation setting. These drugs interfere with the immune system. The main safety concern with their use is the risk of infections.

Unusual presentation of a metastatic esophageal carcinoma.

Esophageal cancer most commonly presents with upper digestive symptoms such as dysphagia. Lymph nodes are among the most common metastatic sites of this type of cancer. We report the case of a 53-year-old man presenting with unusual sole presenting features of esophageal cancer.

Effectiveness of myocardial perfusion scintigraphy to predict coronary anatomy in patients with non-ST elevation acute coronary syndrome.

The risk stratification of conservatively managed patients presenting with non-ST elevation (NSTE) acute coronary syndromes (ACS) is frequently accomplished by the use of myocardial perfusion scintigraphy (MPS) in clinical practice. However, whether one can predict the extent of coronary artery disease (CAD) on angiography by MPS in this setting is unknown. In this study, the correspondence of findings on MPS to those on coronary angiography was retrospectively analyzed in 55 patients presenting with NSTE ACS.

Demyelinating lesions in the cervical cord in multiple sclerosis 10 years after onset of the disease. Correlation between MRI parameters and clinical course.

Background And Purpose: Demyelinating lesions in spinal cord in multiple sclerosis (MS) are found in magnetic resonance imaging (MRI) in 47-90% of patients; spinal cord atrophy, however, which is a measure of axonal loss and correlates with disability, is found in 13-41% of patients. Presence and character of lesions depend on the duration and progression of the disease. The aim of this study was to estimate the presence, character and location of lesions and cervical cord atrophy in MRI performed 10 years after the onset of MS in relation to the clinical course.
