Post-traumatic Stress Disorder01:27

Post-traumatic Stress Disorder

484
Post-traumatic stress disorder (PTSD) is a psychiatric condition that arises following exposure to traumatic events such as natural disasters, forced displacement, or severe accidents. It significantly impairs individuals' ability to cope with daily activities and disrupts their emotional and psychological equilibrium.
Symptoms and Behavioral Manifestations
A spectrum of distressing symptoms characterizes PTSD. Recurrent flashbacks, where individuals involuntarily relive traumatic events,...

Psychosurgery

1.5K
Psychosurgery, the surgical alteration or permanent removal of brain tissue to alleviate severe psychological conditions, stands as one of the most radical and controversial treatments in the history of mental health care. Its development and application have evolved significantly, marked by dramatic shifts in scientific understanding and ethical perspectives.
Historical Development of Psychosurgery
In the 1930s, Portuguese neurologist Antonio Egas Moniz introduced a surgical procedure designed...

Traumatic Memory01:20

Traumatic Memory

551
Emotionally traumatic events often lead to memories that are exceptionally vivid and enduring, sometimes persisting with remarkable clarity throughout an individual's life. A classic example of this phenomenon is a person who survives a car accident. Even years later, they may recall every detail of the event with startling accuracy — the screeching of the tires, the jarring impact, and the acrid smell of burning rubber. Such vividness contrasts sharply with how an individual...

Venous Thrombosis IV: Nursing Management

201
Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration. Review medication intake, particularly oral contraceptives,...

Psychoneuroimmunology: Cardiovascular Disease01:27

Psychoneuroimmunology: Cardiovascular Disease

402
Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...

Area of Science:

  • Trauma Surgery
  • Public Health
  • Epidemiology

Background:

  • Previous research indicates a heightened suicide risk among critically injured patients post-discharge.
  • Existing studies often lack comprehensive data on comorbidities and socioeconomic factors, limiting understanding of this risk.

Purpose of the Study:

  • To investigate the nationwide risk of suicide among individuals hospitalized for traumatic injuries.

Main Methods:

  • A nationwide, register-based cohort study utilized data from Norwegian health registries (2014-2020).
  • Trauma patients (N=25,536) were matched 1:10 with general population controls (N=247,095).
  • Follow-up extended for a minimum of 2 years, with adjustments for comorbidities and socioeconomic position.

Main Results:

  • Trauma patients exhibited a 9-fold increased cumulative incidence ratio (CIR) of suicide at 2 years (CIR, 9.3) compared to controls.
  • Suicide incidence was higher in trauma patients (0.18% at 2 years) versus controls (0.02% at 2 years).
  • Female trauma patients showed a higher incidence of suicide compared to female controls (36% vs 17%).

Conclusions:

  • Hospitalization for traumatic injury is associated with a substantially increased risk of suicide.
  • These findings underscore the importance of psychological support and follow-up for trauma survivors.
  • Further research into the specific risk factors and interventions for suicide prevention in this population is warranted.
