Asthma-I: Introduction

2.6K
Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Asthma-II: Pathophysiology and Classification

2.6K
Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:

Asthma: Pathogenesis and Management

259
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs

182
Asthma is a chronic respiratory condition for which new therapeutic avenues, including anti-inflammatory drugs like mast cell stabilizers and anti-IgE treatments, continue to be developed.
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...

What is Climate?01:16

What is Climate?

18.1K
Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

Area of Science:

  • Environmental Health
  • Allergology
  • Public Health

Background:

  • Climate change poses a significant global health threat, particularly impacting upper airway inflammatory diseases like allergic rhinitis (AR).
  • Global warming trends are demonstrably linked to alterations in environmental factors influencing AR prevalence and symptomology.

Purpose of the Study:

  • To systematically review and characterize the global epidemiological effects of climate change on allergic rhinitis in both adult and pediatric populations.
  • To synthesize current evidence on how climate change influences AR disease patterns and associated healthcare utilization.

Main Methods:

  • A comprehensive literature search was conducted across four databases, adhering to PRISMA guidelines.
  • Inclusion criteria focused on English-language studies published between 2000-2023, reporting on AR epidemiology, climate change factors, and observed impacts on allergy seasons and symptoms.
  • Two independent reviewers screened articles and performed full-text reviews to ensure study eligibility.

Main Results:

  • Out of 502 assessed articles, 30 met the inclusion criteria.
  • Sixteen studies confirmed that climate change leads to longer pollen seasons and/or higher pollen concentrations, with projections of significant increases in North America.
  • Four studies reported increased AR-related healthcare usage, disproportionately affecting low-income populations, and two studies noted a desire among healthcare professionals for more climate change education.

Conclusions:

  • Climate change is actively reshaping the landscape of allergic rhinitis, affecting pollen dynamics, disease prevalence, and symptom severity.
  • The findings underscore a growing recognition among health professionals of climate change's health implications and a demand for enhanced educational resources.
