Summary
The TOP 100 feature in small bowel capsule endoscopy (SBCE) effectively identifies active bleeding and most significant lesions, aiding in rapid diagnosis of small bowel bleeding (SBB). This tool assists in prioritizing urgent cases for intervention.
Area of Science:
- Gastroenterology
- Medical Imaging
- Diagnostic Technology
Background:
- Small bowel capsule endoscopy (SBCE) is the gold standard for diagnosing small bowel bleeding (SBB).
- The RAPID Reader® software introduced the "TOP 100" feature in 2017 for automatic selection of potentially abnormal images.
Purpose of the Study:
- To compare the diagnostic concordance between standard reading (SR) and the TOP 100 feature in SBCE for suspected SBB.
- To evaluate the effectiveness of the TOP 100 in identifying clinically significant lesions.
Main Methods:
- A retrospective study included 97 patients undergoing SBCE for suspected SBB.
- Two experienced readers performed standard reading (SR).
- Another experienced reader, blinded to SR results, reviewed SBCE videos using the TOP 100 feature, identifying high bleeding potential lesions (P2).
Main Results:
- The TOP 100 feature detected 83.5% of P2 lesions, including 95.5% of angioectasias and 56.7% of ulcers.
- All nine identified sites of active bleeding were detected by the TOP 100.
- The TOP 100 identified all active bleeding sites and the vast majority of significant lesions.
Conclusions:
- The TOP 100 feature is a valuable tool for quick preview reading in SBCE.
- It aids in identifying lesions requiring priority review and intervention planning.
- While SR remains the reference standard, TOP 100 enhances efficiency in SBB diagnosis.

784
Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers,...

01:29Reliability and Validity
13.8K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

01:22Bleeding in Fresh Concrete
548
Bleeding in fresh concrete occurs when water from the mix rises to the surface. This happens because the mix's solid components fail to retain all the water as they settle, leading to separation where water collects at the top. The severity of bleeding can be measured by assessing the total settlement or by noting the decrease in height per unit height of concrete.
Bleeding can cause several issues in the concrete structure. Sometimes, the rising water gets trapped beneath large aggregate...

939
Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:

Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...

01:17Chronic Bowel Disorders: Introduction
759
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...
