Magnetic Resonance Imaging Features in Different Types of Invasive Breast Cancer: A Systematic Review of the Literature.

Cureus 2021 Mar 12;13(3):e13854. Epub 2021 Mar 12.

Cardiology, Rush University Medical Center, Chicago, USA.

Breast cancer is the most common malignancy affecting women worldwide, and early diagnosis of breast cancer is the key to its successful and effective treatment. Traditional imaging techniques such as mammography and ultrasound are used to detect and configure breast abnormalities; unfortunately, these modalities have low sensitivity and specificity, particularly in young patients with dense breast tissue, breast implants, or post-surgical scar/architecture distortions. Therefore, breast magnetic resonance imaging (MRI) has been superior in the characterization and detection of breast cancer, especially that with invasive features. Read More

Undergraduate STEM Majors on and off the Pre-Med/Health Track: A STEM Identity Perspective.

CBE Life Sci Educ 2021 Jun;20(2):ar24

STEM Transformation Institute, Florida International University, Miami, FL 33155.

Despite the wealth of research exploring science, technology, engineering, and mathematics (STEM) identity and career goals in both formal and informal settings, existing literature does not consider STEM identity for undergraduate students pursuing health and medical careers through STEM pathways. We address this gap by examining the STEM identity of undergraduate STEM majors on pre-med/health tracks as it compares with that of other STEM majors, thus focusing on a population that is chronically understudied in STEM education research. We surveyed 440 undergraduate STEM students enrolled in entry-level STEM courses to assess their STEM identities and three identity precursors: interest, performance-competence, and recognition.
