Summary
Third space endoscopy, also known as submucosal endoscopy, offers minimally invasive treatments for various gastrointestinal conditions. This technique, including peroral endoscopic myotomy (POEM), is expanding globally for motility disorders and tumors.
Area of Science:
- Gastroenterology and Endoscopic Surgery
- Minimally Invasive Therapeutic Endoscopy
Background:
- Third space endoscopy, or submucosal endoscopy, has been clinically available since 2010.
- It involves accessing the submucosa and deeper gastrointestinal layers via tunneling techniques.
Purpose of the Study:
- To review the current applications and evolving landscape of third space endoscopy.
- To highlight its potential as a standard treatment for various GI pathologies.
Main Methods:
- Utilizes modified submucosal tunneling techniques for endoscopic access.
- Includes peroral endoscopic myotomy (POEM) and its variants.
Main Results:
- Enables treatment of achalasia, esophageal motility disorders, diverticula, and subepithelial tumors.
- Demonstrates potential for treating gastroparesis, esophageal strictures, and pediatric conditions like Hirschsprung's disease.
Conclusions:
- Third space endoscopy procedures are increasingly adopted worldwide.
- Despite ongoing standardization, these techniques are poised to become the standard of care for numerous gastrointestinal conditions.

Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...

Attitude is our evaluation of a person, an idea, or an object. We have attitudes for many things ranging from products that we might pick up in the supermarket to people around the world to political policies. Typically, attitudes are favorable or unfavorable: positive or negative (Eagly & Chaiken, 1993). And, they have three components: an affective component (feelings), a behavioral component (the effect of the attitude on behavior), and a cognitive component (belief and knowledge;...

01:05Introduction to z Scores
431
A z score (or standardized value) is measured in units of the standard deviation. It indicates how many standard deviations the value x is above (to the right of) or below (to the left of) the mean, μ. Values of x that are larger than the mean have positive z scores, and values of x that are smaller than the mean have negative z scores. If x equals the mean, then x has a zero z score. It is important to note that the mean of the z scores is zero, and the standard deviation is one.

In a study where individuals posing as strangers offered compliments and proposed casual sex to students, the responses differed significantly based on gender. Not a single woman accepted the proposal, while 70% of the men agreed. This outcome provides a useful scenario to explore through the lens of evolutionary psychology and social learning theory, highlighting the diverse perspectives on human sexual behaviors.

01:17Properties of the z-Transform I
236
The z-transform is a fundamental tool in digital signal processing, enabling the analysis of discrete-time systems through its various properties. It is an invaluable tool for analyzing discrete-time systems, offering a range of properties that simplify complex signal manipulations. One fundamental property is linearity. For any two discrete-time signals, the z-transform of their linear combination equals the same linear combination of their individual z-transforms. This property is essential...

01:21Pozzolans
161
Pozzolans are siliceous or aluminous materials blended with Portland cement. They interact with the calcium hydroxide produced during the hydration of Portland cement and contribute to improved strength and durability of concrete. The pozzolanic activity, a measure of a pozzolan's effectiveness, is typically assessed using the strength activity index, as defined in ASTM C 618-93, which calculates the ratio of the compressive strength of cement mixtures with and without pozzolan.
