Risk Assessment and QbD-Based Optimization of Sorafenib Tosylate Colon Targeted Bilayer Tablet: In Vitro Characterization, In Vivo Pharmacokinetic, and In Vivo Roentgenography Studies.

AAPS PharmSciTech 2022 Jul 1;23(6):184. Epub 2022 Jul 1.

Department of Pharmaceutics, Poona College of Pharmacy, Bharati Vidyapeeth Deemed University, Pune, 411038, Maharashtra, India.

The employment of site-specific administration in colon is a promising technique to improve efficacy and reduce systemic side effects of anticancer medications used in colorectal cancer. However, the physiology of the gastrointestinal tract and colonic environment limit the efficient delivery of orally administered anticancer drugs to the colon. These prerequisites can be fulfilled by a release modulated colon targeted drug delivery system (CTDDS) based on pH-dependent chronotherapeutic bilayer tablet of sorafenib tosylate (ST). Read More

Prevalence and Clinical Significance of Incidental Focal F-FDG Uptake in Colon on PET/CT Imaging.

Mol Imaging Radionucl Ther 2022 Jun;31(2):96-103

University of Health Sciences Turkey, Prof. Dr. Cemil Taşcıoğlu City Hospital, Clinic of Nuclear Medicine, İstanbul, Turkey.

Objectives: The present study aimed to identify the prevalence of focal uptake in the colon on fluorine-fluorodeoxyglucose (F-FDG) positron emission tomography/computed tomography (PET/CT) studies performed for the evaluation of malignancies other than colon, to detect the rate of malignancy in incidental focal F-FDG avid colonic lesions and to investigate if any possible role of maximum standardized uptake value (SUV) values in the discrimination of malignant lesions from premalignant and benign ones exist.

Methods: We retrospectively reviewed the files of 8,017 patients with known or suspected malignancy, who underwent whole-body F-FDG PET/CT at our institution during the period November 2017 to November 2019. Patients showing a single site of focally increased colonic F-FDG uptake that was more intense compared to liver uptake on F-FDG PET studies and referred to colonoscopy were enrolled in the study.

Therapy response of glucocorticoid-refractory acute GVHD of the lower intestinal tract.

Bone Marrow Transplant 2022 Jun 29. Epub 2022 Jun 29.

Department of Medicine I, Medical Center-University of Freiburg, Faculty of Medicine, Albert Ludwigs University (ALU), Freiburg, Germany.

Acute graft-versus-host disease (aGVHD) is a major life-threatening complication of allogeneic hematopoietic cell transplantation. While most studies report therapy-response of aGVHD including a cumulative grade of skin, liver and intestinal tract manifestations, there is a lack of information specifically on lower gastrointestinal tract aGVHD (GI-GVHD) therapy-response, which is highly relevant in light of novel therapies that target intestinal regeneration such as IL-22, R-spondin or GLP-2. Here we retrospectively analyzed patients who developed GI-GVHD over a 6-year period. Read More

Effect of T1R3 Taste Receptor Gene Deletion on Dextran Sulfate Sodium-Induced Colitis in Mice.

J Nutr Sci Vitaminol (Tokyo) 2022 ;68(3):204-212

Department of Preventive Environment and Nutrition, Institute of Biomedical Sciences, Tokushima University Graduate School.

Taste receptor type 1 member 3 (T1R3) recognize umami or sweet tastes and also contributes type 2 immunity and autophagy in small intestine and muscle cells, respectively. Since imbalance of type 1 and type 2 immunity and autophagy affect intestinal bowel disease (IBD), we hypothesized that T1R3 have a potential role in the incidence and progression of colitis. In the present study, we investigated whether genetic deletion of T1R3 impacted aggravation of DSS-induced colitis in mice. Read More

Effect of 17β-estradiol on the daily pattern of ACE2, ADAM17, TMPRSS2 and estradiol receptor transcription in the lungs and colon of male rats.

PLoS One 2022 28;17(6):e0270609. Epub 2022 Jun 28.

Department of Animal Physiology and Ethology, Faculty of Natural Sciences, Comenius University, Bratislava, Slovak Republic.

Covid-19 progression shows sex-dependent features. It is hypothesized that a better Covid-19 survival rate in females can be attributed to the presence of higher 17β-estradiol (E2) levels in women than in men. Virus SARS-CoV-2 is enabled to enter the cell with the use of angiotensin converting enzyme 2 (ACE2). Read More

TLR4 regulates RORγt regulatory T-cell responses and susceptibility to colon inflammation through interaction with Akkermansia muciniphila.

Microbiome 2022 Jun 27;10(1):98. Epub 2022 Jun 27.

Department of Gastroenterology, The Second Affiliated Hospital of Third Military Medical University, 400037, Chongqing, China.

Background: Well-balanced interactions between gut microbiota and the immune system are essential to prevent chronic intestinal inflammation, as observed in inflammatory bowel diseases (IBD). Toll-like receptor 4 (TLR4) functions as a sensor mediating the crosstalk between the intestinal commensal microbiome and host immunity, but the influence of TLR4 on the shaping of intestinal microbiota and immune responses during colon inflammation remains poorly characterized. We investigated whether the different susceptibilities to colitis between wild-type (WT) and TLR4 mice were gut microbiota-dependent and aimed to identify the potential immunity modulation mechanism.

Defining Sepsis Phenotypes-Two Murine Models of Sepsis and Machine Learning.

Shock 2022 Jun;57(6):268-273

Department of Pathology & Laboratory Medicine, Boston Medical Center, Boston University, Boston, Massachusetts.

Introduction: The immunobiology defining the clinically apparent differences in response to sepsis remains unclear. We hypothesize that in murine models of sepsis we can identify phenotypes of sepsis using non-invasive physiologic parameters (NIPP) early after infection to distinguish between different inflammatory states.

Methods: Two murine models of sepsis were used: gram-negative pneumonia (PNA) and cecal ligation and puncture (CLP). Read More

[Current status of research on short-term urogenital function after transanal total mesorectal excision and laparoscopic total mesorectal excision].

Zhonghua Wei Chang Wai Ke Za Zhi 2022 Jun;25(6):552-557

Department of General Surgery, National Clinical Research Center for Digestive Diseases, Beijing Friendship Hospital, Capital Medical University, Beijing 100050, China.

Thanks to the new surgical approach, transanal total mesorectal excision (taTME) has a better operative field exposure than laparoscopic-assisted total mesorectal excision (laTME), especially for male patients with obesity, pelvic stenosis or prostate hypertrophy. Nevertheless, whether the urogenital function and quality of life after taTME are better as compared to laTME requires further study. According to the existing studies, taTME and laTME are not significantly different in symptoms of the urology system for male patients, but some large sample clinical studies show that the incidence of urethral mechanical injury after taTME is higher.
