Genetic Screens

Genetic Screens

Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...

Social Foundations of Self IV: Self in Digital Communication

Social Foundations of Self IV: Self in Digital Communication

Since the early 2000s, computer-mediated communication (CMC) has grown rapidly, playing a crucial role in self-development. A key distinction between CMC and real-life interactions is the lack of a physically present partner. This absence makes non-verbal cues such as facial expressions, body language, and paralinguistic signals unavailable in CMC platforms like email, instant messaging, or social media. The lack of these cues can create ambiguity and complicate how feedback is interpreted.The...

Schemas

Schemas

A schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

Uncertainty in Measurement: Reading Instruments

Uncertainty in Measurement: Reading Instruments

Counting is the type of measurement that is free from uncertainty, provided the number of objects being counted does not change during the process. Such measurements result in exact numbers. By counting the eggs in a carton, for instance, one can determine exactly how many eggs are there in the carton. Similarly, the numbers of defined quantities are also exact. For example, 1 foot is exactly 12 inches, 1 inch is exactly 2.54 centimeters, and 1 gram is exactly 0.001 kilograms. Quantities...

Uncertainty in Measurement: Significant Figures

Uncertainty in Measurement: Significant Figures

All the digits in a measurement, including the uncertain last digit, are called significant figures or significant digits. Note that zero may be a measured value; for example, if a scale that shows weight to the nearest pound reads “140,” then the 1 (hundreds), 4 (tens), and 0 (ones) are all significant (measured) values.

Molecular Models

Molecular Models

Physical models representing molecular architectures of chemical compounds play essential roles in understanding chemistry. The use of molecular models makes it easier to visualize the structures and shapes of atoms and molecules.

Summary

Screening mammography use declined sharply in 2010 after years of growth, coinciding with guideline changes. Digital breast tomosynthesis (DBT) use was limited in 2015, appearing in under 20% of digital mammograms.

Background:

Recent advancements in breast imaging include updated screening guidelines and the introduction of digital breast tomosynthesis (DBT).
Understanding screening mammography utilization trends is crucial for assessing population health and healthcare resource allocation.

Purpose of the Study:

To evaluate screening mammography utilization trends in the Medicare population from 2005 to 2015.
To examine the volume of digital breast tomosynthesis (DBT) studies performed in 2015.

Main Methods:

Analysis of national Medicare Part B Physician/Supplier Procedure Summary master files (2005-2015).
Determination of annual screening mammography utilization rates using procedure codes for film-screen and digital mammography.
Calculation of screening and diagnostic DBT study volumes in 2015.

Main Results:

Screening mammography utilization increased from 2005 to 2009 (peak 322.9/1000 women), then declined 4.3% in 2010 (309.2/1000 women) and did not recover.
In 2015, DBT was an add-on procedure in 18.9% of screening and 16.2% of diagnostic digital mammography examinations.

Conclusions:

A significant, sustained decline in screening mammography utilization began in 2010, following U.S. Preventive Services Task Force recommendations.
Digital breast tomosynthesis (DBT) adoption was limited in 2015, used in less than one-fifth of digital mammography procedures.
