Competition02:34

Competition

25.3K
When organisms require the same limited resources within an environment, they may have to compete for them. Competition is a net-negative interaction. Even if two competing individuals or populations do not interact directly, the overall fitness of both competitors is lowered as a result of not having full access to the limited resource.

Infection01:20

Infection

13.8K
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Healthcare Associated Infections II: Preventive Measures

4.7K
Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Defense Against Bacterial Pathogens01:31

Defense Against Bacterial Pathogens

3.3K
The human immune system is a complex network of cells, tissues, and organs that work together to defend the body against bacterial infections. It consists of various immune cells, each playing a specific role in the defense mechanism.
Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...

Stages of Infection01:26

Stages of Infection

66.5K
Stages of infection describe what happens to a susceptible host once a pathogen invades the human body. The stages of infection are incubation, prodromal, illness, stage of decline, and convalescence. The incubation stage is the period from exposure to a pathogen until symptoms start. The infected person is unaware of impending illness as the pathogens grow and multiply within the body. The duration may vary depending on the type of infection. The incubation period of measles averages ten to...

Acute Pyelonephritis II: Diagnostic Studies and Management

579
Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

Area of Science:

  • Medical Education
  • Infectious Diseases
  • Pedagogy

Background:

  • Problem/case-based learning (PCBL) is a prevalent educational strategy in medical schools.
  • Severe infection courses present unique challenges for clinical training.
  • Enhancing PCBL effectiveness is crucial for medical student competency.

Purpose of the Study:

  • To evaluate the impact of introducing a competition mode into PCBL for a severe infection clinical course.
  • To assess if competition enhances student engagement and learning outcomes.

Main Methods:

  • Two groups of medical students received PCBL for severe infection.
  • A competition element was integrated into the study group (35 students) but not the control group (36 students).
  • Performance was evaluated through case analysis in a final examination, focusing on severe infection and infectious shock.

Main Results:

  • Students in the competition group showed increased activity in discussions, article referencing, and consultations.
  • The competition group demonstrated superior performance in the final case analysis.
  • The case analysis effectively identified high-achieving students in the competition-based PCBL group.

Conclusions:

  • PCBL incorporating a competition mode is effective for understanding severe infection diagnosis and treatment.
  • Competition stimulates student initiative in referencing literature and attending consultations.
  • This enhanced PCBL approach is vital for developing clinical practice competency in medical students.
