Fatigue01:21

Fatigue

255
Fatigue occurs when materials rupture under repeated or fluctuating loads, even at stress levels far below their static breaking strength. It typically results in brittle failure, even for ductile materials. It is a critical consideration in designing machines and structural components subjected to repetitive or varying loads. The nature of these loadings can range from fluctuating loads like unbalanced pump impellers causing vibrations to repeatedly bending a thin steel rod wire back and forth...

Muscle Recovery and Fatigue01:24

Muscle Recovery and Fatigue

2.7K
Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective...

COPD: Pathogenesis and Clinical Features

582
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Post-traumatic Stress Disorder

131
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,...

Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

Area of Science:

  • Neurology
  • Psychiatry
  • Infectious Diseases

Background:

  • Post-coronavirus disease 2019 (COVID-19) is defined by the WHO as persistent symptoms lasting over two months after SARS-CoV-2 infection.
  • Core symptoms include fatigue, dyspnea, and cognitive dysfunction, significantly impacting daily life.
  • Neuropsychiatric sequelae, such as sleep disorders, depression, and anxiety, affect over 30% of COVID-19 patients.

Purpose of the Study:

  • To investigate the nature and management of post-COVID syndrome, focusing on fatigue and associated neuropsychiatric symptoms.
  • To explore the interplay between fatigue, psychiatric comorbidities, and potential treatment strategies.

Main Methods:

  • Review of current literature and meta-analyses on post-viral fatigue.
  • Analysis of imaging studies indicating organic correlates of fatigue.
  • Identification of psychosocial factors and psychiatric comorbidities influencing post-COVID syndrome.

Main Results:

  • Fatigue is a key symptom with overlaps and comorbidities with psychiatric disorders.
  • Neuropsychiatric symptoms, including depression and anxiety, are common and may modulate post-COVID syndrome.
  • Imaging studies suggest an organic basis for fatigue in post-COVID patients.

Conclusions:

  • Post-COVID syndrome presents with significant fatigue and neuropsychiatric manifestations.
  • Psychosocial factors and comorbidities like depression and anxiety are treatable modulators.
  • Treatment strategies encompass pharmacological (stimulants, antidepressants) and non-pharmacological (CBT, exercise) approaches.
