Retrograde-viewing device improves adenoma detection rate in colonoscopies for surveillance and diagnostic workup

AIM:To determine which patients might benefit most from retrograde viewing during colonoscopy through subset analysis of randomized,controlled trial data.METHODS:The Third Eye Retroscope Randomized Clinical Evaluation(TERRACE) was a randomized,controlled,multicenter trial designed to evaluate the efficacy of a retrograde-viewing auxiliary imaging device that is used during colonoscopy to provide a second video image which allows viewing of areas on the proximal aspect of haustral folds and flexures that are difficult to see with the colonoscope's forward view.We performed a post-hoc analysis of the TERRACE data to determine whether certain subsets of the patient population would gain more benefit than others from use of the device.Subjects were patients scheduled for colonoscopy for screening,surveillance or diagnostic workup,and each underwent same-day tandem examinations with standard colonoscopy(SC) and Third Eye colonoscopy(TEC),randomized to SC followed by TEC or vice versa.RESULTS:Indication for colonoscopy was screening in 176/345 subjects(51.0%),surveillance after previous polypectomy in 87(25.2%) and diagnostic workup in 82(23.8%).In 4 subjects no indication was specified.Previously reported overall results had shown a net additional adenoma detection rate(ADR) with TEC of 23.2% compared to SC.Relative risk(RR) of missing adenomas with SC vs TEC as the initial procedure was 1.92(P = 0.029).Post-hoc subset analysis shows additional ADRs for TEC compared to SC were 4.4% for screening,35.7% for surveillance,55.4% for diagnostic and 40.7% for surveillance and diagnostic combined.The RR of missing adenomas with SC vs TEC was 1.11(P = 0.815) for screening,3.15(P = 0.014) for surveillance,8.64(P = 0.039) for diagnostic and 3.34(P = 0.003) for surveillance and diagnostic combined.Although a multivariate Poisson regression suggested gender as a possibly significant factor,subset analysis showed that the difference between genders was not statistically significant.Age,bowel prep quality and withdrawal time did not significantly affect the RR of missing adenomas with SC vs TEC.Mean sizes of adenomas detected with TEC and SC were similar at 0.59 cm and 0.56 cm,respectively(P = NS).CONCLUSION:TEC allows detection of significantly more adenomas compared to SC in patients undergoing surveillance or diagnostic workup,but not in screening patients(ClinicalTrials.gov Identifier:NCT01044732).

Surveillance of patients following surgery with curative intent for colorectal cancer

Surveillance after resection of colorectal cancer with curative intent is an important component of post- operative care. Clinical review, imaging, colonoscopy, and cost to the community are among significant issues to consider in planning a surveillance regime. This review aims to identify the available evidence for the use of surveillance and its individual components. The literature pertaining to follow-up of patients following potentially curative surgery for colorectal cancer was reviewed in order to formulate a summary of the wide range of clinical practice. There is evidence of improved survival of patients undergoing more intense follow-up compared with those having minimal surveillance, with an estimated overall 5-year gain of up to 10%. The efficacy of individual components of follow-up regimes remains unclear, but an overall package of 'intensive' follow-up including clinical review, liver imaging, and colonoscopy appears to be of benefit. It is cost-effective and can be specialist or community-based.

Quality audit of colonoscopy reports amongst patients screened or surveilled for colorectal neoplasia

AIM： To complete a quality audit using recently pub- lished criteria from the Quality Assurance Task Group of the National Colorectal Cancer Roundtable. METHODS： Consecutive colonoscopy reports of patients at average/high risk screening, or with a prior col6rectal neoplasia （CRN） by endoscopists who perform 11 000 procedures yearly, using a commercial computerized endoscopic report generator. A separate institutional da- tabase providing pathological results. Required documen- tation included patient demographics, history, procedure indications, technical descriptions, colonoscopy findings, interventions, unplanned events, follow-up plans, and pathology results. Reports abstraction employed a stan- dardized glossary with 10% independent data validation. Sample size calculations determined the number of re- ports needed.RESULTS： Two hundreds and fifty patients （63.2± 10.5 years, female： 42.8%, average risk： 38.5%, per- sonal/family history of CRN： 43.3%/20.2%） were scoped in June 2009 by 8 gastroenterologists and 3 surgeons （mean practice： 17.1 ± 8.5 years）. Procedural indica- tion and informed consent were always documented. 14% provided a previous colonoscopy date （past polyp removal information in 25%, but insufficient in most to determine surveillance intervals appropriateness）. Most procedural indicators were recorded （exam date： 98.4%, medications： 99.2%, difficulty level： 98.8%, prep quality： 99.6%）. All reports noted extent of visualization （cecum： 94.4%, with landmarks noted in 78.8% - photodocu- mentation： 67.2%）. No procedural times were recorded. One hundred and eleven had polyps （44.4%） with ana- tomic location noted in 99.1%, size in 65.8%, morphol- ogy in 62.2%; removal was by cold biopsy in 25.2% （cold snare： 18%, snare cautery： 31.5%, unrecorded： 20.7%）, 84.7% were retrieved. Adenomas were noted in 24.8% （advanced adenomas： 7.6%, cancer： 0.4%） in this population with varying previous colonic investigations. CONCLUSION： This audit reveals lacking reported ite- ms, justifying additional research to optimize quality of reporting.

DCFl-Checker： Checking Kernel Dynamic Control Flow Integrity with Performance Monitoring Counter

It is a challenge to verify integrity of dynamic control flows due to their dynamic and volatile nature. To meet the challenge, existing solutions usually implant an ＂attachment＂ in each control transfer. However, the attachment introduces additional cost except performance penalty. For example, the attachment must be unique or restrictedly modified. In this paper, we propose a novel approach to detect integrity of dynamic control flows by counting executed branch instructions without involving any attachment. Our solution is based on the following observation. If a control flow is compromised, the number of executed branch instructions will be abnormally increased. The cause is that intruders usually hijack control flows for malicious execution which absolutely introduces additional branch instructions. Inspired by the above observation, in this paper, we devise a novel system named DCFI- Checker, which detect integrity corruption of dynamic control flows with the support of Performance Monitoring Counter （PMC）. We have developed a proof-of-concept prototype system of DCFI-Checker on Linux fedora 5. Our experiments with existing kemel rootkits and buffer overflow attack show that DCFI- Checker is effective to detect compromised dynamic control transfer, and performance evaluations indicate that performance penaltyinduced by DCFI-Checker is acceptable.

THE MEASUREMENT AND APPLICATION OF TSH－IRMA LEVELS AMONG DIFFERENT AGE GROUPS IN AREAS WITH IODINE DEFICIENCY DISORDERS

Using immunoradiornetric TSH assay (TSH-IRMA) to measure whole blood TSH levels spotted onto filter paper, we compared TSH levels among different age groups (neonates, <1 yr infants, schoolchildren aged 7 to 14 yrs, adults,pregnant women and reproductive-age women) in Guiyang, where iodine deficiency has long been a problem. The results showed: 1) The percentage of subjects with TSH levels equal to or greater than 5 mIU/L in the neonate group was 38.9% while the percentages in the other groups were 0-3.3% (P<0.01); 2)The TSH levels of the neonates were inversely related to the urinary iodine values of their mothers (pregnant women). (r=-0. 5, P<0. 01);3)97.6% of the inhabitants in Guiyang ingested salt with less than 20mg/kg iodine. The results indicate that iodine deficiency remains a problem in Guiyang. Neonates are the only ideal population for monitoring iodine deficiency.

Transoesophageal echo-doppler hemodynamic monitoring during preoperative acute hypervolemic hemodilution

Using transesophageal echo-Doppler, it is demonstrated that preoperative acute hypervolemic hemodilution(HHD) with 6% hydroxyethel starch(HES) significantly increased in intravascular volume, DO2, CO, SV and CI, markedly decreased in SVR and remained stable in MAP and HR, which indicates HES infused at 20 ml*kg-1 is safe in patient without cardiac disease.

Drug Therapy Monitoring in Patients with Type 2 Diabetes and Hypertension

The aim of this paper is to detect, prevent and resolve DRP （drug-related problems） and NOM （negative outcomes associated with medication） in hospitalized patients with DM2 （type 2 diabetes） with HTN （hypertension） in a tertiary care clinic. Descriptive cross-sectional interventional study is used. DTM （drug therapy monitoring） was conducted in 73 patients using data obtained from clinical histories and interviews. NOM were detected based on symptoms and laboratory test results. The statistical significance was 0.05. It can be found that 23 DRP were detected, primarily in the category ＂likelihood of adverse effects＂ （30.43%） causing NOM in the ＂non-quantitative safety problem＂ category. The NOM detected were related to safety （62%）, effectiveness （24.5%） and necessity （13.5%）. Of the 68.57% of pharmacist interventions accepted, 48.57% were resolved and 20% were not resolved. A simple linear correlation （r = -0.34） analysis indicated a weak association between patient age and severity ofNOM. DTM made it＇possible to detect suspected DRP and NOM, which were then prevented or resolved, improving the control of HTN and DM2 and helping ensure better drug therapy outcomes for patients.
