Endoscopy Unit Level Interventions to Improve Adenoma Detection Rate: A Systematic Review and Meta-Analysis.

Background & Aims: Adenoma detection rate (ADR) is inversely correlated with the risk of interval colon cancer and is a key target for quality improvement in endoscopy units. We conducted a systematic review and meta-analysis to identify and evaluate the effectiveness of interventions that can be implemented at the endoscopy unit level to improve ADRs.

Methods: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a systematic search was conducted in MEDLINE, Embase, and Cochrane Central Register of Controlled Trials databases between January 1990 and December 2022 to identify relevant studies.

Association of Trainee Participation in Colonoscopy Procedures With Quality Metrics.

Importance: Trainees routinely participate in colonoscopy procedures, yet whether their involvement is positively or negatively associated with procedural quality is unknown because prior studies involved small number of trainees and/or supervisors, lacked generalizability, and/or failed to adjust for potential confounders.

Objective: To assess the association between trainee participation and colonoscopy quality metrics.

Design, Setting, And Participants: This multicenter population-based cohort study was conducted at 21 academic and community hospitals between April 1, 2017, and October 31, 2018, among consecutive adult patients undergoing colonoscopy.

VIBe Scale: Validation of the Intraoperative Bleeding Severity Scale by Spine Surgeons.

Background: The Validated Intraoperative Bleeding Scale (VIBe Scale) was initially validated with surgeons who operate on cardiothoracic, abdominal, and pelvic cavities and fulfilled criteria for a clinician-reported scale. However, there is a need for a tool to aid in intraoperative blood management during spine surgeries. The purpose of the present study was to establish the reliability and consistency of the VIBe Scale as a tool for spine surgeons to assess intraoperative bleeding.

EVIVO is a well-established chronic disease self-management program, having been successfully implemented during the last decade in Switzerland. The program has shown positive results in facilitation of self-management competences for patients living with chronic diseases and their relatives. EVIVO was designed to run for 6 weeks with weekly sessions of 2 and a half hour each.

Investigating the Effect of Vibrotactile Feedback in Transfemoral Amputee With and Without Movable Ankle Joint.

The loss of somatosensory feedback after transfemoral amputation imposes a serious challenge in achieving postural stability. In the recent past, weight shifting exercises with fixed ankle joint have been reported useful in boosting the limit of stability (LOS) only in the sound limb; the LOS on the prosthetic limb did not improve. A fixed ankle joint restricts movement in the anterior-posterior direction at the ankle level.

Floseal only versus in combination in spine surgery: a comparative, retrospective hospital database evaluation of clinical and healthcare resource outcomes.

Objective: Flowable agents such as Floseal® (F) are often reserved as adjuncts to non-flowable agents (i.e. gelatin (G) sponges and thrombin (T)) when bleeding is not sufficiently controlled.

A Multicenter Radiographic Evaluation of the Rates of Preoperative and Postoperative Malalignment in Degenerative Spinal Fusions.

Study Design: Multicenter, retrospective, institutional-review-board -approved study at 18 institutions in the United States with 24 treating investigators.

Objective: This study was designed to retrospectively assess the prevalence of spinopelvic malalignment in patients who underwent one- or two-level lumbar fusions for degenerative (nondeformity) indications and to assess the incidence of malalignment after fusion surgery as well as the rate of alignment preservation and/or correction in this population.

Summary Of Background Data: Spinopelvic malalignment after lumbar fusion has been associated with lower postoperative health-related quality of life and elevated risk of adjacent segment failure.

Impact of experience on self-assessment accuracy of clinical colonoscopy competence.

Background And Aims: Self-assessment is important for life-long learning and a recommended assessment method for endoscopy skills. Prior literature has not investigated self-assessment accuracy of colonoscopic competence in the clinical setting. This study aimed to determine the self-assessment accuracy of novice, intermediate, and experienced endoscopists.

A prospective comparison of live and video-based assessments of colonoscopy performance.

Background And Aims: Colonoscopy performance is typically assessed by a supervisor in the clinical setting. There are limitations of this approach, however, because it allows for rater bias and increases supervisor workload demand during the procedure. Video-based assessment of recorded procedures has been proposed as a complementary means by which to assess colonoscopy performance.

A Mobile Food Record For Integrated Dietary Assessment.

This paper presents an integrated dietary assessment system based on food image analysis that uses mobile devices or smartphones. We describe two components of our integrated system: a mobile application and an image-based food nutrient database that is connected to the mobile application. An easy-to-use mobile application user interface is described that was designed based on user preferences as well as the requirements of the image analysis methods.

The effect of small solar powered 'Bͻkͻͻ' net fans on mosquito net use: results from a randomized controlled cross-over trial in southern Ghana.

Background: Long-lasting insecticidal nets (LLINs) are ineffective malaria transmission prevention tools if they are unused. Discomfort due to heat is the most commonly reported reason for not using nets, but this problem is largely unaddressed. With increasing rural electrification and the dropping price of solar power, fans could improve comfort inside nets and be affordable to populations in malaria endemic areas.

Effect of PEGylation on performance of protein microbubbles and its comparison with lipid microbubbles.

Aqueous suspensions of microbubbles are being used in various biomedical applications such as contrast imaging, targeted drug and gene delivery, delivery of drugs through blood brain barrier (BBB) and IV O delivery etc. Major microbubble formulations use either proteins or lipids as their shell material. Protein microbubble formulations mainly consist of serum albumin, lysozyme etc.

Objective: To examine reliability and validity evidence of the Gastrointestinal Endoscopy Competency Assessment Tool (GiECAT) for colonoscopy for use within the clinical setting.

Design: Prospective, observational, multicenter validation study.

Multiple hypotheses image segmentation and classification with application to dietary assessment.

We propose a method for dietary assessment to automatically identify and locate food in a variety of images captured during controlled and natural eating events. Two concepts are combined to achieve this: a set of segmented objects can be partitioned into perceptually similar object classes based on global and local features; and perceptually similar object classes can be used to assess the accuracy of image segmentation. These ideas are implemented by generating multiple segmentations of an image to select stable segmentations based on the classifier's confidence score assigned to each segmented image region.

ANALYSIS OF FOOD IMAGES: FEATURES AND CLASSIFICATION.

In this paper we investigate features and their combinations for food image analysis and a classification approach based on k-nearest neighbors and vocabulary trees. The system is evaluated on a food image dataset consisting of 1453 images of eating occasions in 42 food categories which were acquired by 45 participants in natural eating conditions. The same image dataset is used to test the classification system proposed in the previously reported work [1].

Computer-based virtual reality colonoscopy simulation improves patient-based colonoscopy performance.

Background: Colonoscopy simulators that enable one to perform computer-based virtual colonoscopy now exist. However, data regarding the effectiveness of this virtual training are limited.

Objective: To determine whether virtual reality simulator training translates into improved patient-based colonoscopy performance.

A Mobile Phone User Interface for Image-Based Dietary Assessment.

Many chronic diseases, including obesity and cancer, are related to diet. Such diseases may be prevented and/or successfully treated by accurately monitoring and assessing food and beverage intakes. Existing dietary assessment methods such as the 24-hour dietary recall and the food frequency questionnaire, are burdensome and not generally accurate.

Gastrointestinal Endoscopy Competency Assessment Tool: development of a procedure-specific assessment tool for colonoscopy.

Background: Ensuring competence remains a seminal objective of endoscopy training programs, professional organizations, and accreditation bodies; however, no widely accepted measure of endoscopic competence currently exists.

Objective: By using Delphi methodology, we aimed to develop and establish the content validity of the Gastrointestinal Endoscopy Competency Assessment Tool for colonoscopy.

Design: An international panel of endoscopy experts rated potential checklist and global rating items for their importance as indicators of the competence of trainees learning to perform colonoscopy.

Image-Based Food Volume Estimation.

In this paper, we propose an extension to our previous work on food portion size estimation using a single image and a multi-view volume estimation method. The single-view technique estimates food volume by using prior information (segmentation and food labels) generated from food identification methods we described earlier. For multi-view volume estimation, we use"Shape from Silhouettes"to estimate the food portion size.
