Infection01:20

Infection

12.7K
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...

Stages of Infection

65.3K
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...

Defense Mechanism Against Infection01:26

Defense Mechanism Against Infection

9.8K
Natural flora, body system defenses, and inflammation are natural barriers of the body against infectious agents regardless of previous exposure. Normal floras of the human body refer to the microbial population that colonizes the skin and mucous membranes.
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...

Sexually Transmitted Infections01:26

Sexually Transmitted Infections

1.1K
Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

13.7K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Healthcare Associated Infections II: Preventive Measures01:22

Healthcare Associated Infections II: Preventive Measures

4.1K
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...

Area of Science:

  • * Psychiatry
  • * Infectious Diseases
  • * Public Health

Background:

  • * The intersection of human immunodeficiency virus (HIV) infection and suicidality is a complex and critical area of research.
  • * Previous literature highlights HIV as a potential risk factor for various suicidal behaviors.
  • * Understanding this relationship is crucial for developing targeted interventions and support systems.

Purpose of the Study:

  • * To conduct a comprehensive review of the published literature over the past decade on HIV-spectrum pathology and suicidality.
  • * To analyze the multifaceted relationship between HIV infection and diverse forms of suicidal behavior, including completed suicide, suicide attempts, deliberate self-harm (DSH), and suicidal ideation.
  • * To explore a unifying conceptual framework for understanding the overlap between HIV and suicide behavior.

Main Methods:

  • * Systematic review of scientific literature published within the last 10 years.
  • * Analytical examination of studies focusing on HIV-related pathology and various dimensions of suicidal behavior.
  • * Literature search encompassing completed suicide, attempted suicide, DSH, and suicidal thoughts in the context of HIV.

Main Results:

  • * HIV infection is identified as a notable risk factor contributing to suicidal behavior.
  • * The review distinguishes and analyzes different forms of suicidal behavior (completed suicide, attempts, DSH, thoughts) in individuals with HIV.
  • * A significant overlap exists between HIV-infectious pathology and the spectrum of suicide behavior.

Conclusions:

  • * The concept of 'mosaicism' is proposed as a unifying framework to understand the complex interplay between HIV pathology and suicide behavior.
  • * Recognizing HIV as a suicide risk factor necessitates integrated care approaches.
  • * Further research is warranted to elucidate the specific mechanisms underlying this relationship and to inform clinical practice and public health strategies.
