In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.
Percentiles are a type of fractile that partition data into...

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

Adult Stem Cells01:33

Adult Stem Cells

33.4K
Stem cells are undifferentiated cells that divide and produce more stem cells or progenitor cells that differentiate into mature, specialized cell types. All the cells in the body are generated from stem cells in the early embryo, but small populations of stem cells are also present in many adult tissues including the bone marrow, brain, skin, and gut. These adult stem cells typically produce the various cell types found in that tissue—to replace cells that are damaged or to continuously...

Cardiopulmonary Resuscitation I: Adult

626
Cardiopulmonary resuscitation, or CPR, is a life-saving emergency procedure performed when a person's heart has stopped beating or they are no longer breathing. The foundation of CPR is Basic Life Support (BLS), which focuses on the early recognition of cardiac arrest, the immediate start of high-quality chest compressions, and the timely use of an automated external defibrillator (AED).Assessing Responsiveness and Checking the Carotid PulseWhen approaching an unresponsive person, first ensure...

Relationship with Other Adult Family Members and Siblings

176
Other adult family members and siblings play a crucial role in shaping children’s social and emotional development. While parents or primary caregivers are often the central figures in early attachment and socialization, other adults in a child’s life, such as grandparents, aunts, and uncles, can significantly influence developmental outcomes. These influences depend on each adult’s personality and may help compensate when a primary caregiver is emotionally distant or...

Revisionist Views of Adolescent and Adult Cognition01:24

Revisionist Views of Adolescent and Adult Cognition

289
A revisionist approach to Jean Piaget's theory of cognitive development has brought new insights that challenge and reinterpret his established ideas. Piaget proposed that the formal operational stage, emerging in adolescence, represents the culmination of cognitive maturity. During this stage, individuals are said to develop abstract thinking, engage in systematic problem-solving, and show a form of egocentrism, believing others are as preoccupied with their behavior as they are...

Area of Science:

  • Neuro-oncology
  • Central Nervous System (CNS) Tumors
  • Molecular Pathology

Background:

  • Ependymomas are rare primary CNS tumors in adults, predominantly affecting the spinal cord.
  • Histological grading (WHO grades I-III) traditionally classifies ependymomas based on anaplasia.
  • Recent findings reveal genetic heterogeneity within histological subgroups and distinct molecular signatures based on CNS origin.

Purpose of the Study:

  • To discuss the current histopathological and molecular classification of ependymomas.
  • To review current patient management guidelines for ependymomas.
  • To present a case study of a spinal cord ependymoma.

Main Methods:

  • Case presentation of a 46-year-old female with spinal cord ependymoma.
  • Review of current literature on ependymoma classification and management.
  • Discussion of molecular profiling in ependymoma research.

Main Results:

  • Ependymomas exhibit significant molecular heterogeneity, even within the same histological grade.
  • Different CNS locations yield ependymomas with distinct molecular profiles.
  • Current treatment outcomes with radiation and chemotherapy are variable and often poor.

Conclusions:

  • Molecular profiling is crucial for developing targeted therapies for ependymomas.
  • Understanding molecular signatures can guide personalized treatment strategies.
  • Further research into molecular-based treatments is warranted for improved patient outcomes.
