Factors Affecting Illness01:18

Factors Affecting Illness

4.8K
When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness,...

Theoretical Approaches to Psychological Disorder01:29

Theoretical Approaches to Psychological Disorder

472
The development of psychological disorders, which are characterized by deviant, maladaptive, and personally distressing behaviors, has been explored through several theoretical approaches.
Biological approach
The biological approach posits that internal, organic factors are the primary causes of such disorders. This perspective emphasizes brain structure and function, genetic predispositions, and neurotransmitter imbalances. For example, schizophrenia has been associated with both genetic...

Respiratory disorders encompass a range of conditions with varying levels of severity. Asthma, marked by chronic airway inflammation and hypersensitivity, is one such condition. It can lead to airway obstruction due to factors like bronchial spasms, mucosal edema, increased mucus secretion, or epithelial damage. Asthma triggers are diverse, ranging from allergens to emotional upset, and treatment focuses on both immediate relief through bronchodilators and long-term inflammation suppression.

Diagnostic and Statistical Manual of Mental Disorders (DSM)01:27

Diagnostic and Statistical Manual of Mental Disorders (DSM)

538
The Diagnostic and Statistical Manual of Mental Disorders (DSM) serves as the primary classification system for mental health disorders, providing standardized diagnostic criteria for clinicians and researchers. First published by the American Psychiatric Association (APA) in 1952, the DSM has undergone several revisions to reflect evolving psychiatric understanding. The fifth edition, DSM-5, released in 2013, introduced key updates that expanded diagnostic categories and modified diagnostic...

Obsessive-Compulsive Disorder01:28

Obsessive-Compulsive Disorder

318
Obsessive-compulsive disorder (OCD) is a mental health condition characterized by recurrent obsessions, compulsions, or both, which consume significant time and interfere with daily functioning. Obsessions involve persistent, intrusive, and unwanted thoughts, images, or urges that evoke anxiety. Common examples include irrational fears of contamination or harm. Compulsions are repetitive behaviors or mental acts performed to reduce the anxiety caused by obsessions. For instance, individuals...

Pharmacokinetics: Drug–Food and Drug–Viral Interactions01:26

Pharmacokinetics: Drug–Food and Drug–Viral Interactions

83
A drug interaction occurs when the concurrent use of another drug, food, or an external substance alters the pharmacological activity of a drug. This interaction can modify the action of the original drug, affecting its effectiveness and safety.Drug–food interactions are significant as they impact drug absorption, metabolism, and excretion. For example, grapefruit juice is a well-known disruptor of drug metabolism. It inhibits the cytochrome P450 3A4 enzyme, crucial for the metabolism of...

Area of Science:

  • Medical Science
  • Infectious Diseases
  • Public Health

Background:

  • Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes Coronavirus disease (COVID-19), a global pandemic.
  • COVID-19 symptoms range from mild to severe, including respiratory distress, sepsis, and death.
  • Comorbidities are prevalent in COVID-19 patients, affecting disease severity and prognosis.

Purpose of the Study:

  • To review the impact of common comorbidities on COVID-19 prognosis.
  • To understand how pre-existing conditions influence the severity of SARS-CoV-2 infection outcomes.
  • To identify comorbidities associated with increased risk of severe COVID-19 and ICU admission.

Main Methods:

  • Literature review of studies on COVID-19 and comorbidities.
  • Analysis of reported comorbidities in hospitalized COVID-19 patients.
  • Synthesis of data on the association between specific comorbidities and disease severity.

Main Results:

  • Approximately 50% of hospitalized COVID-19 patients have at least one comorbidity.
  • Hypertension, diabetes, COPD, obesity, and cardiovascular diseases are frequently reported comorbidities.
  • Comorbidities are linked to poorer prognosis and increased risk of severe COVID-19 symptoms, with 70% of ICU patients having comorbidities.

Conclusions:

  • Comorbidities significantly worsen the prognosis of COVID-19.
  • Patients with pre-existing conditions face a higher risk of severe illness and adverse outcomes from SARS-CoV-2 infection.
  • Understanding comorbidity impact is vital for managing COVID-19 patients and predicting disease trajectory.
