Colorectal cancer (CRC) is the second leading cause of cancer-related deaths in the United States. Colonoscopy can prevent CRC by the detection and removal of precancerous lesions. In addition to CRC screening and surveillance, colonoscopy is used widely for the diagnostic evaluation of symptoms and other positive CRC screening tests. Regardless of indication, the success of colonoscopy is link...

In this paper, we emphasize the need for data cleansing when clustering large-scale transaction databases and propose a new data cleansing method that improves clustering quality and performance. We evaluate our data cleansing method through a series of experiments. As a result, the clustering quality and performance were significantly improved by up to 165% and 330%, respectively.

With an increase in the number of dependent elderly, there is a need to introduce few natural products for denture cleansing, which are easily and economically available. Hence the aim of this study was to compare the anticandidal efficacy of denture cleansing tablet (sodium bicarbonate and sodium perborate monohydrate), Triphala (Phyllanthus emblica, Terminalia chebula and Terminalia belerica ...

Medical data is unique due to its large volume, heterogeneity and complexity. This necessitates costly active participation of medical domain experts in the task of cleansing medical data. In this paper we present a new data cleansing approach that utilizes Bayesian networks to correct errant attribute values. Bayesian networks capture expert domain knowledge as well as the uncertainty inherent...

Recently a psychological mechanism has been proposed between bodily purity and moral purity: the "Macbeth effect". The act of washing their hands seems to free individuals of their guilt. However, the universality of this psychological mechanism is an empirical question that should be studied. In four studies we replicated the original Zhong & Liljenquist's experiments with Spanish samples. We ...

Burn wound cleansing is an integral step in every wound management protocol. Yet a lot of this practice is based on myth rather than real scientific basis. The literature is poor in scientific papers comparing the outcome of patients who underwent wound cleansing to those who did not. A survey form was designed by the Mediterranean Council for Burns and Fire Disasters - MBC and sent by e-mail t...

OBJECTIVE To evaluate whether vaginal cleansing reduces the risk of postoperative infection after abdominal total hysterectomy on benign indications and to analyze risk factors. DESIGN Retrospective cohort study. SETTING All clinics including patients in the Swedish National Register for Gynecological Surgery. POPULATION All 7,193 women who underwent abdominal total hysterectomy for benig...

BACKGROUND AND STUDY AIMS Neoplastic lesions can be missed during colonoscopy, especially when cleansing is inadequate. Bowel preparation scales have significant limitations and no objective and standardized method currently exists to establish colon cleanliness during colonoscopy. The aims of our study are to create a software algorithm that is able to analyze bowel cleansing during colonoscop...

Virtual colonoscopy is a non-invasive technique for the detection of polyps. Currently, a clean colon is required; as without cleansing the colonic wall cannot be segmented. Enhanced bowel preparation schemes opacify intraluminal remains to enable colon segmentation. Computed cleansing (as opposed to physical cleansing of the bowels) allows removal of tagged intraluminal remains. This paper des...

BACKGROUND The ideal bowel cleansing regimen for colonoscopy has yet to be determined. OBJECTIVE To compare the cleansing efficacy, and patient tolerability and safety of four bowel preparation regimens. METHODS A total of 834 patients undergoing outpatient colonoscopy were randomly assigned to one of four regimens: 4 L polyethylene glycol (PEG); 2 L PEG + 20 mg bisacodyl; 90 mL of sodium p...
