BACKGROUND: The contents of the guinea pig distal colon consist of multiple pellets that move anally in a coordinated manner. This row of pellets results in continued distention of the colon. In this study, we have investigated quantitatively the features of the neurally dependent colonic motor patterns that are evoked by constant distension of the full length of guinea-pig colon. METHODS: Constant distension was applied to the excised guinea-pig by high-resolution manometry catheters or by a series of hooks...

Carbapenemase-producing Enterobacteriaceae are increasing worldwide. Rectal screening for these bacteria can inform the management of infected and colonized patients, especially those admitted to intensive care units (ICUs). A laboratory developed, qualitative duplex real-time polymerase chain reaction assay for rapid detection of OXA-48-like and VIM producing Enterobacteriaceae, performed on rectal swabs, was designed and evaluated in an intensive care unit with endemic presence of OXA-48. During analytical assay validation, no cross-reactivity was observed and 100% sensitivity and specificity were obtained for both blaOXA-48-like and blaVIM in all spiked clinical samples...

The regulation of gastrointestinal motility encompasses several overlapping mechanisms including highly regulated and coordinated neurohormonal circuits. Various feedback mechanisms or 'brakes' have been proposed. While duodenal, jejunal, and ileal brakes are well described, a putative distal colonic brake is less well defined. Despite the high prevalence of colonic motility disorders, there is little knowledge of colonic motility owing to difficulties with organ access and technical difficulties in recording detailed motor patterns along its entire length...

BACKGROUND: Catheter-Associated Hospital-Acquired Infections (HAI's) are caused by biofilm-forming bacteria. Using a novel approach, we generated anti-infective barrier on catheters by charging them with Nitric Oxide (NO), a naturally-produced gas molecule. NO is slowly released from the catheter upon contact with physiological fluids, and prevents bacterial colonization and biofilm formation onto catheter surfaces. AIMS AND METHODS: The aim of the study was to assess the anti-infective properties of NO-charged catheters exposed to low concentration (up to 103 CFU/ml) of microbial cells in-vitro...

Patients suffering from spinal cord injuries resulting in complete or incomplete paraplegia or tetraplegia are highly disposed to frequent, recurrent or even chronic urinary tract infections (UTIs). The reason for the increased risk of acquiring UTIs is multifactorial, including reduced sensation of classical UTI symptoms, incomplete bladder emptying, frequent catheterizations or chronic urinary tract catheters. Biofilms in relation to UTIs have been shown both on catheters, on concrements or as intracellular bacterial communities (IBCs)...

The use of central venous catheters (CVC) is associated with a risk of microbial colonization and subsequent potentially severe infection. Microbial contamination of the catheter leads to the development of a microbial consortia associated with the CVC surface and embedded in an extracellular matrix, named biofilm. This biofilm provides bacterial cells the ability to survive antimicrobial agents and the host immune system and to disseminate to other sites of the body. The best preventive strategy is to avoid any unnecessary catheterization or to reduce indwelling duration when a CVC is required...

Urinary tract infections are one of the most common infectious diseases diagnosed in the community and in the hospital setting. Their treatment is complicated by drug-resistant pathogens and the colonization by microbes of indwelling urinary catheters. This study assessed the occurrence and antimicrobial susceptibility of methicillin-resistant Staphylococcus aureus (MRSA) uropathogens isolated for 5 consecutive years at University Hospital Waterford between 2010 and 2014. We created 4 clinically relevant subdivisions, based on urine source: hospital inpatients, patients from the Emergency Department, patients referred from their General Practitioner, and Nursing Home patients...

OBJECTIVE: Multiresistant, vancomycin-nonsusceptible Staphylococcus capitis is an emerging cause worldwide of late-onset sepsis (LOS) in preterm neonates. The pathophysiology and risk factors for S. capitis-related LOS are poorly understood but we hypothesized that S. capitis LOS follows translocation from the gut microbiota rather than catheter invasion. The objective of this study was to investigate the risk factors of S. capitis LOS and gut colonization. METHODS: We conducted a prospective monocentric cohort study of patients hospitalized in a tertiary care unit (Lyon, France) from June 2011 to January 2012...

Serratia marcescens is a Gram-negative bacterium with proven resistance to multiple antibiotics and causative of catheter-associated infections. Bacterial colonization of catheters mainly involves the formation of biofilm. The objectives of this study were to explore the susceptibility of S. marcescens biofilms to high doses of common antibiotics and non-antimicrobial agents. Biofilms formed by a clinical isolate of S. marcescens were treated with ceftriaxone, kanamycin, gentamicin, and chloramphenicol at doses corresponding to 10, 100 and 1000 times their planktonic minimum inhibitory concentration...

Purpose - Percutaneous nephrostomy (PCN) catheters are the primary method for draining ureters obstructed by malignancy and preventing a decline of the renal function. However, PCN-related infections such as pyelonephritis and urosepsis remain a significant concern. Currently no antimicrobial PCNs are available for preventing infectious complications. Vascular catheters impregnated with Minocycline/Rifampin (M/R) and M/R with Chlorhexidine coating (M/R+CHD) have previously demonstrated antimicrobial activity...

BACKGROUND: We evaluated the change in colon manometry (CM) parameters and interpretation comparing results when the study is performed the same day after the motility catheter is placed under anesthesia or the following day. METHODS: CM catheter was placed with colonoscopy under anesthesia and recorded on day 1 and repeated on day 2. Study parameters including motility index during fasting, post-prandial and post-Bisacodyl challenge phase; gastrocolonic response; number, presence and propagation of high amplitude propagating contractions (HAPCs); and, study interpretation were compared between both the days...

The prevention of catheter-related blood stream infections (CRBSI) in hemodialysis (HD) patients remains a challenge because of high morbidity and mortality associated to CRBSI. Alternative locking solutions (ALS) containing an antithrombotic substance with additional antimicrobial or antibiofilm properties (citrate, ethylenediaminetetraacetic acid [EDTA], 70% ethanol, thrombolytics) with or without the addition of molecules with specific antimicrobial activity (antibiotics, taurolidine, paraben-methylene-blue) has been proposed with the aim to prevent or eradicate intraluminal biofilm colonization and subsequent CRBSI...

A 34-year-old para V woman was referred to our centre at 35+1 weeks of gestation for an assumed fetal malformation with prenatal renal impairment and anhydramnios. Prenatal ultrasound demonstrated unilateral renal agenesis; the bladder was not detectable. The baby was born by caesarian section at 36+2 weeks of gestation because of placental insufficiency. Postnatal adaptation was uneventful, but the newborn presented external stigmas of trisomy 21 and progressive renal impairment with anuria. Nevertheless, the postnatal ultrasound showed two enlarged kidneys in loco typico with impaired perfusion but without signs of malformations...

In selected centers, colonic manometry with non-high-resolution catheters is used to document colonic motor dysfunction in chronic constipation. Recently, high-resolution manometry (HRM) catheters, with more closely spaced sensors have been used for this purpose. Corestti et al. assessed colonic pressures with HRM in 17 healthy people and 10 constipated patients. The main finding was pan-colonic pressurizations, which occurred frequently, increased after eating and cholinergic stimulation, were associated with the desire to pass flatus, and were less frequent in slow-transit constipation...

In this project, fluid flow and fluid-structure interaction are studied for the human lower gastrointestinal (GI) region. The study consists of two steps. First, we apply meshing methods to discretize both the human lower GI model and the catheter model at sufficient resolution suitable for importing into a Finite Element Analysis (FEA) tool. For model discretization, 3D models of the colon reconstructed from human MRI slices are used to obtain the valid inlet and outlet boundary surfaces. To resolve the viscous boundary layer in flow studies, a special structure of the near-wall volumetric mesh is built by triangular prisms that construct quasi-structured, multiple near-boundary sub-layers...

BACKGROUND: Ureteral injuries during colorectal surgery are a rare event, ranging in the literature from 0.28-7.6%. Debate surrounds the use of prophylactic lighted ureteral stents to help protect the ureter during laparoscopic surgery. It has been suggested that they help to identify injuries but do not prevent them. The authors look to challenge this. METHODS: Over 66 months, every laparoscopic or colectomy involving ureteral stents was recorded. Researchers documented any injury to the ureter intraoperatively...
