Andrew Iraniha, Joshua Peloquin
Laparoscopic TAPP inguinal hernia repair is an established alternative to open hernia repair, which offers equivalent outcomes with less postoperative pain and faster recovery. Unfortunately, it remains technically challenging, requiring advanced laparoscopic skills which have limited its popularity among surgeons. The robotic platform has the potential to overcome these challenges. The objective of this study was to examine the long-term quality of life and outcomes following robotic assisted TAPP inguinal hernia repair, since these data have not been reported up to now...

Dysfunction of the gut-blood barrier (GBB) plays a pivotal role in various diseases, including trauma, haemorrhagic shock (HS) and burn injury, as well as inflammatory bowel diseases (IBD). Whereas GBB disruption significantly contributes to IBD, the exact extent and consequences of GBB failure and its reliable determination in the clinical course following trauma remain rather unclear. A compromised GBB function seems to contribute to remote organ injury after trauma by generation of inflammatory mediators and biologically active lymph, which in turn augments the inflammatory response...

Life stress is a major risk factor in the onset and exacerbation of mast cell-associated diseases, including allergy/anaphylaxis, asthma, and irritable bowel syndrome. Although it is known that mast cells are highly activated upon stressful events, the mechanisms by which stress modulates mast cell function and disease pathophysiology remains poorly understood. Here, we investigated the role of corticotropin-releasing factor receptor subtype 1 (CRF1) in mast cell degranulation and associated disease pathophysiology...

Granulocyte and monocyte (GM) adsorptive apheresis (GMA) is an effective therapy for inflammatory disorders including inflammatory bowel disease (IBD). During GMA, the blood of a patient with IBD passes through a column to contact cellulose acetate (CA) beads at a temperature below body temperature, likely close to room temperature. Here we investigated the effect of temperature on GM adsorption to CA beads in vitro. We incubated peripheral blood with and without CA beads at 5°C, 25°C, 37°C, and 43°C and calculated the ratios of adsorbed GMs...

Interstitial cells of Cajal (ICC) in the myenteric plexus region (ICC-MY) of the small intestine are pacemakers that generate rhythmic depolarizations known as slow waves. Slow waves depend on activation of Ca(2+)-activated Cl(-) channels (ANO1) in ICC, propagate actively within networks of ICC-MY, and conduct to smooth muscle cells where they generate action potentials and phasic contractions. Thus, mechanisms of Ca(2+) regulation in ICC are fundamental to the motor patterns of the bowel. Here, we characterize the nature of Ca(2+) transients in ICC-MY within intact muscles, using mice expressing a genetically encoded Ca(2+) sensor, GCaMP3, in ICC...

OBJECTIVES To estimate the incidence and identified risk factors for community-acquired (CA) and hospital-acquired (HA) Clostridium difficile infection (CDI) METHODS We conducted 2 parallel case-control studies at Tel Aviv Sourasky Medical Center from January 1, 2011, to December 31, 2014. We identified persons with CDI, determined whether infection was community or hospital acquired, and calculated incidence rates from 2007 to 2014. We collected demographic, clinical, and epidemiological information for CDI cases and hospitalized control cases and estimated the odds ratio with 95% confidence interval using conditional logistic regression...

New therapeutic strategies against inflammatory bowel disease (IBD) consider the usage of probiotics, prebiotics and synbiotics as beneficial for the intestinal microbial balance. Limitations of such an approach are addressed into difference in survival, persistence, colonization and variable effects among different probiotic strains, lack in understanding of probiotic mechanisms of action, as well the complex etiology of IBD. The anti-inflammatory activity of Lactobacillus casei 01 (L. casei 01) was assessed in trinitrobenzenesulphonic (TNBS) acid model of rat colitis when the probiotic was used alone and/or in combination with oligofructose-enriched inulin (Synergy 1), and as synbiotic (L...

BACKGROUND: Tissue adhesives (TA) may be useful to strengthen colorectal anastomoses, thereby preventing anastomotic leakage (AL). Previous studies have identified cyanoacrylate (CA) TAs as the most promising colonic anastomotic sealants. This study investigates the protective effects of sealing colonic anastomoses with various CAs. MATERIALS AND METHODS: Fifty-five Wistar rats underwent laparotomy and transection of the proximal colon. An anastomosis was created with 4 interrupted sutures followed by either application of Histoacryl Flexible, Omnex, Glubran 2, or no TA seal...

BACKGROUND: An impairment of the integrity of the mucosal epithelial barrier can be observed in the course of various gastrointestinal diseases. The migration and proliferation of the intestinal epithelial (IEC-6) cells are essential repair modalities to the healing of mucosal ulcers and wounds. Atractylenolide I (AT-I), one of the major bioactive components in the rhizome of Atractylodes macrocephala Koidz. (AMR), possesses multiple pharmacological activities. This study was designed to investigate the therapeutic effects and the underlying molecular mechanisms of AT-I on gastrointestinal mucosal injury...

BACKGROUND: Ewing's sarcoma (ES) and primitive neuroectodermal tumors (PNET) are closely related tumors. Although soft tissue ES/PNET are common in clinical practice, they are rare in the small intestine. Because of the absence of characteristic clinical symptoms, they are easily misdiagnosed as other benign or malignant diseases. CASE PRESENTATION: Here, we present the case of a 16-year-old female who complained of anemia and interval hematochezia. Her serum test results showed only a slight elevation of CA-125 and a low level of hemoglobin...

Intestinal epithelial cells form a tight barrier to act as selective physical barriers, repelling hostile substances. Tumor necrosis factor-α (TNF-α) is a well characterized pro-inflammatory cytokine which can compromise intestinal barrier function and the suppression of TNF-α function is important for treatment of inflammatory bowel disease (IBD). In this study, we investigated the contribution of G-protein-coupled receptor (GPCR)-induced signalling pathways to the maintenance of epithelial barrier function...

BACKGROUND: We previously showed that mucosal biopsy supernatants from irritable bowel syndrome patients activated neurons despite low concentrations of tryptase, histamine, and serotonin which individually would not cause spike discharge. We studied the potentiating responses between these mediators on excitability of enteric neurons. METHODS: Calcium-imaging was performed using the calcium-sensitive dye Fluo-4 AM in human submucous plexus preparations from 45 individuals...

Intestinal fibrosis, a complication of inflammatory bowel disease, is currently being addressed by surgery alone, with no adequate alternative therapy available for patients. We propose that anti-inflammatory plant substances like cinnamon extract (CE) or its main compound cinnamaldeyde (CA) could aid in therapy. We recently found CE reducing inflammation in murine colitis. Here, we analysed effects of CE on fibrosis in IL-10(-/-) colitis METHODS AND RESULTS: IL-10(-/-) and wild type (wt) mice were orally treated with/without vehicle or CE...

Conventional oral drug formulations for colonic diseases require the administration of high doses of drug to achieve effective drug concentrations at the target site. However, this exposes patients to serious systemic toxicity in order to achieve efficacy. To overcome this problem, an oral drug delivery system was developed by loading a large amount (ca. 34% w/w) of prednisolone into 3-aminopropyl-functionalized mesoporous silica nanoparticles (MCM-NH2) and targeting prednisolone release to the colon by coating the nanoparticle with succinylated ε-polylysine (SPL)...

Nutrient-sensing receptors, including fatty acid receptors (FFA1-FFA4), Ca(2+)-sensing receptors and Zn(2+)-sensing receptors, are involved in several biological processes. These receptors are abundantly expressed in the GI tract, where they have been shown to play crucial roles in regulating GI function. This review provides an overview of the GI functions of fatty acid and mineral receptors, including the regulation of gastric and enteroendocrine functions, GI motility, ion transport and cell growth. Recently, several lines of evidence have implicated these receptors as promising therapeutic targets for the treatment of GI disorders, for example, inflammatory bowel disease, colorectal cancer, metabolic syndrome and diarrheal diseases...

Opioid drugs are prescribed extensively for pain treatment but when used chronically they induce constipation that can progress to opioid-induced bowel dysfunction. Opioid drugs interact with three classes of opioid receptors: mu opioid receptors (MORs), delta opioid receptors (DOR), and kappa opioid receptors (KORs), but opioid drugs mostly target the MORs. Upon stimulation, opioid receptors couple to inhibitory Gi/Go proteins that activate or inhibit downstream effector proteins. MOR and DOR couple to inhibition of adenylate cyclase and voltage-gated Ca(2+) channels and to activation of K(+) channels resulting in reduced neuronal activity and neurotransmitter release...
