[Ti] Título:WITHDRAWN: Intermittent catheterisation for long-term bladder management.
[So] Source:Cochrane Database Syst Rev;8:CD006008, 2017 08 08.

[La] Idioma:eng
[Ab] Resumo:BACKGROUND: Intermittent catheterisation is a commonly recommended procedure for people with incomplete bladder emptying. There are now several designs of intermittent catheter (e.g. different lengths, 'ready to use' presentation) with different materials (e.g. PVC-free) and coatings (e.g. hydrophilic). The most frequent complication of intermittent catheterisation is urinary tract infection (UTI), but satisfaction, preference and ease of use are also important to users. It is unclear which catheter designs, techniques or strategies affect the incidence of UTI, which are preferable to users and which are most cost effective. OBJECTIVES: To compare one type of catheter design versus another, one type of catheter material versus another, aseptic catheterisation technique versus clean technique, single-use (sterile) catheters versus multiple-use (clean) catheters, self-catheterisation versus catheterisation by others and any other strategies designed to reduce UTI and other complications or improve user-reported outcomes (user satisfaction, preference, ease of use) and cost effectiveness in adults and children using intermittent catheterisation for incomplete bladder emptying. SEARCH METHODS: We searched the Cochrane Incontinence Group Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE in process, and handsearching of journals and conference proceedings (searched 30 September 2013), the reference lists of relevant articles and conference proceedings, and we attempted to contact other investigators for unpublished data or for clarification. SELECTION CRITERIA: Randomised controlled trials (RCTs) or randomised cross-over trials comparing at least two different catheter designs, catheterisation techniques or strategies. DATA COLLECTION AND ANALYSIS: Two review authors assessed the methodological quality of trials and abstracted data. For dichotomous variables, risk ratios and 95% confidence intervals were derived for each outcome where possible. For continuous variables, mean differences and 95% confidence intervals were calculated for each outcome. Because of trial heterogeneity, it was not always possible to combine data to give an overall estimate of treatment effect. MAIN RESULTS: Thirty-one trials met the inclusion criteria, including 13 RCTs and 18 cross-over trials. Most were small (less than 60 participants completed), although five trials had more than 100 participants. There was considerable variation in length of follow-up and definitions of UTI. Participant dropout was a problem for several trials, particularly where there was long-term follow-up to measure incidence of UTI. Fifteen trials were more than 10 years old and focused mainly on comparing different catheterisation techniques (e.g. single versus multiple-use) on clinical outcomes whereas, several more recent trials have focused on comparing different types of catheter designs or materials, especially coatings, and user preference. It was not possible to combine data from some trials owing to variations in the catheters tested and in particular the catheter coatings. Where there were data, confidence intervals around estimates were wide and hence clinically important differences in UTI and other outcomes could neither be identified nor reliably ruled out. No study assessed cost-effectiveness. AUTHORS' CONCLUSIONS: Despite a total of 31 trials, there is still no convincing evidence that the incidence of UTI is affected by use of aseptic or clean technique, coated or uncoated catheters, single (sterile) or multiple-use (clean) catheters, self-catheterisation or catheterisation by others, or by any other strategy. Results from user-reported outcomes varied. The current research evidence is weak and design issues are significant. More well-designed trials are strongly recommended. Such trials should include analysis of cost-effectiveness because there are likely to be substantial differences associated with the use of different catheter designs, catheterisation techniques and strategies.

[Ti] Título:Randomized Comparison of 3 High-Level Disinfection and Sterilization Procedures for Duodenoscopes.
[So] Source:Gastroenterology;153(4):1018-1025, 2017 Oct.
[Is] ISSN:1528-0012

[La] Idioma:eng
[Ab] Resumo:BACKGROUND AND AIMS: Duodenoscopes have been implicated in the transmission of multidrug-resistant organisms (MDRO). We compared the frequency of duodenoscope contamination with MDRO or any other bacteria after disinfection or sterilization by 3 different methods. METHODS: We performed a single-center prospective randomized study in which duodenoscopes were randomly reprocessed by standard high-level disinfection (sHLD), double high-level disinfection (dHLD), or standard high-level disinfection followed by ethylene oxide gas sterilization (HLD/ETO). Samples were collected from the elevator mechanism and working channel of each duodenoscope and cultured before use. The primary outcome was the proportion of duodenoscopes with an elevator mechanism or working channel culture showing 1 or more MDRO; secondary outcomes included the frequency of duodenoscope contamination with more than 0 and 10 or more colony-forming units (CFU) of aerobic bacterial growth on either sampling location. RESULTS: After 3 months of enrollment, the study was closed because of the futility; we did not observe sufficient events to evaluate the primary outcome. Among 541 duodenoscope culture events, 516 were included in the final analysis. No duodenoscope culture in any group was positive for MDRO. Bacterial growth of more than 0 CFU was noted in 16.1% duodenoscopes in the sHLD group, 16.0% in the dHLD group, and 22.5% in the HLD/ETO group (P = .21). Bacterial growth or 10 or more CFU was noted in 2.3% of duodenoscopes in the sHLD group, 4.1% in the dHLD group, and 4.2% in the HLD/ETO group (P = .36). MRDOs were cultured from 3.2% of pre-procedure rectal swabs and 2.5% of duodenal aspirates. CONCLUSIONS: In a comparison of duodenoscopes reprocessed by sHLD, dHLD, or HLD/ETO, we found no significant differences between groups for MDRO or bacteria contamination. Enhanced disinfection methods (dHLD or HLD/ETO) did not provide additional protection against contamination. However, insufficient events occurred to assess our primary study end-point.

[Ab] Resumo:French Army Health Service provides medical support for armed forces deployed on external missions.In order to ensure the same health care quality in the theatre and in the metropolis, the Military Health Service provides sterilization of reusable medical devices by its own means. Army pharmacists carrying out an on-site mission comes from different domains: medical biology laboratory, research, medical supplies, hospital pharmacy or yet pharmaceutical laboratory for some reservists. Training program for sterilization in isolated military operations areas is therefore necessary in order to ensure knowledge uniformity. Our study is organized in two parts: determination of the needs and of the adapted training modalities, then implementation of training itself. This training should be accessible to a geographically dispersed public whose levels of expertise in sterilization are disparate. The module «Préparation opérationnelle à la stérilisation en Opération Extérieure¼ carried out allows to update and standardize the knowledge of the deployed pharmacists. It is composed of 11 sub-modules covering the different aspects of sterilization during external missions. Assessment using multiple-choice questions (MCQ) is necessary to check the level of knowledge and to understanding at the end of the training. A 75% good response rate is requested to validate the training. Training content has been approved by the National referents for sterilization and it is already available on the e-learning platform of the École du Val de Grâce.

[Ab] Resumo:BACKGROUND: Numerous published outbreaks, including one from our institution, have described endoscope-associated transmission of multidrug-resistant organisms (MDROs). Individual centers have adopted their own protocols to address this issue, including endoscope culture and sequestration. Endoscope culturing has drawbacks and may allow residual bacteria, including MDROs, to go undetected after high-level disinfection. AIM: To report the outcome of our novel protocol, which does not utilize endoscope culturing, to address our outbreak. METHODS: All patients undergoing procedures with elevator-containing endoscopes were asked to permit performance of a rectal swab. All endoscopes underwent high-level disinfection according to updated manufacturer's guidance. Additionally, ethylene oxide (EtO) sterilization was done in the high-risk settings of (1) positive response to a pre-procedure risk stratification questionnaire, (2) positive or indeterminate CRE polymerase chain reaction (PCR) from rectal swab, (3) refusal to consent for PCR or questionnaire, (4) purulent cholangitis or infected pancreatic fluid collections. Two endoscopes per weekend were sterilized on a rotational basis. RESULTS: From September 1, 2015 to April 30, 2016, 556 endoscopy sessions were performed using elevator-containing endoscopes. Prompted EtO sterilization was done on 46 (8.3%) instances, 3 from positive/indeterminate PCR tests out of 530 samples (0.6%). No CRE transmission was observed during the study period. Damage or altered performance of endoscopes related to EtO was not observed. CONCLUSION: In this pilot study, prompted EtO sterilization in high-risk patients has thus far eliminated endoscope-associated MDRO transmission, although no CRE infections were noted throughout the institution during the study period. Further studies and a larger patient sample will be required to validate these findings.

[Ab] Resumo:OBJECTIVE To determine effects of repeated use and resterilization on structural and functional integrity of microwave ablation (MWA) antennas. SAMPLE 17 cooled-shaft MWA antennas (3 groups of 5 antennas/group and 2 control antennas). PROCEDURES 1, 2, and 3 ablations in the livers of bovine cadavers were performed at the maximum recommended settings. Antennas were cleaned and sterilized in hydrogen peroxide plasma, and the process was repeated (reprocessing cycle; n = 6). Control antennas were only sterilized (6 times). Aerobic and anaerobic bacterial cultures were performed, and antennas were microscopically assessed for damage. RESULTS 6 cycles were completed. Thirteen of 15 MWA antennas remained functional for up to 4 cycles, 10 were functional after 5 cycles, and only 7 were functional after 6 cycles. Progressive tearing of the silicone coating of the antennas was observed, with a negative effect of the number of cycles for silicone tearing. Size of the ablation zone decreased mildly over time after cycles 5 and 6; however, this was not considered clinically relevant. No significant changes in the shape of ablation zones were detected. All cultures yielded negative results, except for an isolated case, which was considered a contaminant. CONCLUSIONS AND CLINICAL RELEVANCE Structural and functional integrity of the microwave antennas remained acceptable during repeated use and reprocessing for up to 4 cycles. However, there was a decrease in functional integrity at cycles 5 and 6. We suggest that these microwave antennas be subjected to > 3 reprocessing cycles. Antennas should be carefully examined before reuse.

[Ab] Resumo:OBJECTIVE: Thialkalivibrio versutus D301 cells were immobilized on Fe O nanoparticles (NPs) synthesized by an improved chemical coprecipitation method and modified with 3-aminopropyltriethoxysilane (APTES), then the immobilized cells were used in sulfur oxidation. RESULTS: The prepared Fe O -APTES NPs had a narrow size distribution (10 ± 2 nm) and were superparamagnetic, with a saturation magnetization of 60.69 emu/g. Immobilized cells had a saturation magnetization of 34.95 emu/g and retained superparamagnetism. The optimum conditions for cell immobilization were obtained at pH 9.5 and 1 M Na . The immobilization capacity of Fe O -APTES NPs was 7.15 g DCW/g-NPs that was 2.3-fold higher than that of Fe O NPs. The desulfurization efficiency of the immobilized cells was close to 100%, having the same sulfur oxidation capacity as free cells. Further, the immobilized cells could be reused at least eight times, retaining more than 85% of their desulfurization efficiency. CONCLUSION: Immobilization of cells with the modified magnetic NPs efficiently increased cell controllability, have no effect on their desulfurization activity and could be effectively used in large-scale industrial applications.

[Ab] Resumo:BACKGROUND: Reprocessed (re-sterilized) bipolar energy devices represent one effort to reduce operative costs. METHODS: Between January 2014 to October 2015, 76 patients underwent laparoscopic colectomy using a reprocessed bipolar energy device and were case-matched to 76 patients from a prospectively-maintained database from November 2012 to December 2013 when an identical, new device was used. Outcomes included reprocessed device safety, efficiency and hospital costs. RESULTS: There was no difference in patient demographics, operative times or failed pedicle ligation requiring intervention between groups (all P > 0.05). In 19.7% of reprocessed cases, the surgeon opened an additional new device after dissatisfaction with the reprocessed instrument. Operating room costs and total costs were less for the reprocessed device group (all P < 0.05). CONCLUSION: Reprocessed bipolar energy devices were associated with savings in operative expenses, however, larger studies are warranted due to the high surgeon dissatisfaction regarding safety concerns with the reprocessed equipment.
