BACKGROUND Following implementation of bundled practices in 2009 in Quebec and Canadian intensive care units (ICUs), we describe CLABSI epidemiology during the last 8 years in the province of Québec (Canada) and compare rates with Canadian and American benchmarks. METHODS CLABSI incidence rates (IRs) and central venous catheter utilization ratios (CVCURs) by year and ICU type were calculated using 2007-2014 data from the Surveillance Provinciale des Infections Nosocomiales (SPIN) program. Using American and Canadian surveillance data, we compared SPIN IRs to rates in other jurisdictions using standardized incidence ratios (SIRs)...

BACKGROUND & AIMS: Chronic Intestinal Failure (CIF) is the long-lasting reduction of gut function, below the minimum necessary for the absorption of macronutrients and/or water and electrolytes, such that intravenous supplementation is required to maintain health and/or growth. CIF is the rarest organ failure. Home parenteral nutrition (HPN) is the primary treatment for CIF. No guidelines (GLs) have been developed that address the global management of CIF. These GLs have been devised to generate comprehensive recommendations for safe and effective management of adult patients with CIF...

BACKGROUND: Central venous catheterization (CVC) is a basic requirement for many medical specialties. Simulated training in CVC may allow the acquisition of this competency but few reports have established a valid methodology for learning and acquiring procedural skills for CVC. This study aims to validate the use of a tracking motion device, the imperial college surgical assessment device (ICSAD), by comparing it with validated global rating scales (GRS) to measure CVC performance in a simulated torso...

Microvascular dysfunction contributes to the development of cardiovascular and metabolic disease. This study tested the hypothesis that young obese (BMI>30 kg m(-2)), otherwise healthy, adults (N=15) have impaired microvascular function relative to age and sex matched, lean (BMI<25 kg m(-2)) individuals (N=14). Participants were instrumented with two microdialysis probes in the cutaneous vasculature of one forearm; one for a wide dose range of infusions of the endothelium-dependent vasodilator methacholine (MCh) and the other for the endothelium-independent vasodilator sodium nitroprusside (SNP)...

BACKGROUND: Guidelines and clinical practice for the prevention of complications associated with central venous catheters (CVC) around the world vary greatly. Most institutions recommend the use of heparin to prevent occlusion, however there is debate regarding the need for heparin and evidence to suggest 0.9% sodium chloride (normal saline) may be as effective. The use of heparin is not without risk, may be unnecessary and is also associated with increased cost. OBJECTIVES: To assess the clinical effects (benefits and harms) of intermittent flushing of heparin versus normal saline to prevent occlusion in long term central venous catheters in infants and children...

Colon cancer is one of the most commonly diagnosed cancers, and is a major cause of cancer morbidity and mortality worldwide. The objective of the present study is to evaluate the combined therapeutic efficacy of carvacrol (CVC) and X-radiation against 1,2-dimethylhydrazine-induced colon cancer. Male albino Wistar rats were randomly divided into six groups. Group 1 served as control; group 2 received 40 mg/kg b.wt of CVC orally everyday throughout the experimental period (32 weeks); groups 3-6 received subcutaneous injections of DMH (20 mg/kg b...

Patients with end-stage renal disease (ESRD) on dialysis have poor overall survival, and cardiovascular (CV) is the main cause of mortality among these patients. Coronary calcification is an independent predictor of mortality and CV events in dialysis patients and can be accessed by using a computerized tomography scanning. The high cost of this procedure, however, precludes routine implementation of this method for the purposes of risk stratification. Aortic arch calcification has been associated with CV mortality in the general population...

BACKGROUND: Blood stream infections (BSIs) are a common source of morbidity and death in hospitalized patients. We hypothesized that the proportions of bacteremia from gram-positive and fungal pathogens have decreased over time, whereas rates of gram-negative bacteremia have increased as a result of better central venous catheter management. METHODS: All U.S. Centers for Disease Control and Prevention-defined BSIs in patients treated on the general surgery and trauma services at our institution between January 1, 1998, and December 31, 2009 were identified prospectively...

INTRODUCTION: Continuous infusion (CI) of clotting factors has facilitated surgical procedures and intensive replacement therapy in haemophilia patients. This procedure could, however, be further optimized by using a short-term central venous catheter (CVCs) instead of via peripheral venous access. AIM: In this paper, we present our results on using a short-term CVC in haemophilia patients during major surgical operations. METHODS: In total, 40 patients with haemophilia A or B (37 and 3, respectively), aged 21-81 years, underwent 67 surgeries with 65 CVCs...

BACKGROUND: There is ongoing debate about the use of transposed basilic vein (TBV) fistula and the choice between it and prosthetic arteriovenous graft (AVG). This paper reviews the available literature relating to TBV fistula in terms of surgical technique, patency rates, complications, access survival and compares it with prosthetic AVG for hemodialysis (HD). METHODS: Review of English language publications on TBV during the last two decades. FINDINGS: The rate of fistula maturation was higher in the two-stage group, although the mean diameter of the basilic vein was smaller...

This study evaluated the separate and combined roles of nitric oxide synthase (NOS) and cyclooxygenase (COX) in forearm sweating and cutaneous vasodilatation in older adults during intermittent exercise in the heat. Twelve healthy older (62 ± 7 years) males performed two 30 min cycling bouts at a fixed rate of metabolic heat production (400 W) in the heat (35°C, 20% relative humidity). The exercise bouts were followed by 20 and 40 min of recovery, respectively. Forearm sweat rate (ventilated capsule) and cutaneous vascular conductance (CVC, laser Doppler perfusion units/mean arterial pressure) were evaluated at four skin sites that were continuously perfused via intradermal microdialysis with: (1) lactated Ringer solution (Control), (2) 10 mm ketorolac (non-selective COX inhibitor), (3) 10 mm N(G) -nitro-l-arginine methyl ester (l-NAME; non-selective NOS inhibitor) or (4) a combination of 10 mm ketorolac + 10 mm l-NAME...

Probiotics are helpful in the treatment of acute diarrhea. Several systematic reviews show that the use of probiotics shortens the duration of diarrhea in one day and reduces by 59% the risk of diarrhea lasting longer than 4 days. Hospital stay is 24 hours shorter in children treated with probiotics. The benefitial effect of probiotics is species-specific; Lactobacillus rhamnosus GG and Saccharomyces boulardii are the two species with proven efficacy in the treatment of acute diarrhea. The use of probiotics reduces by 50% the risk of antibiotic-associated diarrhea...

OBJECTIVE: To observe oxygen uptake efficiency plateau (OUEP, i.e.highest V˙O2/V˙E) and carbon dioxide output efficiency (lowest V˙E/V˙CO2) parameter changes during exercise in normal subjects. METHODS: Five healthy volunteers performed the symptom limited maximal cardiopulmonary exercise test (CPET) at Harbor-UCLA Medical Center. V˙O2/V˙E and V˙E/V˙CO2 were determined by both arterial and central venous catheters. After blood gas analysis of arterial and venous sampling at the last 30 seconds of every exercise stage and every minute of incremental loading, the continuous parameter changes of hemodynamics, pulmonary ventilation were monitored and oxygen uptake ventilatory efficiency (V˙O2/V˙E and V˙E/V˙CO2) was calculated...

Central venous catheter-related fungemia are increasing in the last years, also due to rare fungi. We report the case of a Candida utilis catheter-related bloodstream infection in a patient with metastatic carcinoma of the bladder and a long term totally implanted venous catheter. The diagnosis was done by paired blood cultures and differential time to positivity. The Candida species was rapidly identified by MALDI-TOF mass spectrometry. The patient was successfully treated with anidulafungine.
