Summary
Occupational asthma (OA) is preventable. Primary prevention strategies show benefit, and medical surveillance aids outcomes, though further research on optimal programs is needed.
Area of Science:
- Occupational health
- Pulmonology
- Environmental medicine
Background:
- Occupational factors contribute to ~10% of adult-onset asthma.
- Occupational asthma (OA) is a prevalent occupational lung disease in industrialized regions.
- Persistent asthma has significant socio-economic consequences.
Purpose of the Study:
- To review the literature on the prevention of occupational asthma.
- To assess the effectiveness of primary, secondary, and tertiary prevention strategies for OA.
Main Methods:
- A literature search was conducted using PubMed.
- The search terms included "occupational asthma" and "prevention".
Main Results:
- Primary prevention is effective for OA linked to natural rubber latex and may reduce diisocyanate-induced asthma.
- Medical health surveillance has shown effectiveness in industries like detergent enzymes, platinum salts, and for diisocyanate workers.
- Tertiary prevention remains necessary for managing existing OA and improving patient prognosis.
Conclusions:
- Occupational asthma is potentially preventable through various strategies.
- Primary prevention methods have demonstrated clear benefits.
- Medical surveillance, occupational hygiene, and worker education improve outcomes, but further studies are needed to optimize these programs.
- Tertiary prevention is crucial until primary and secondary prevention are better understood and implemented.

01:25Transmission-based Precautions II: Airborne and Protective Environment
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

01:29Asthma-I: Introduction
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...
01:30Asthma-IV: Nursing Management
The nursing management of asthma is a comprehensive approach that relies heavily on the expertise and dedication of healthcare professionals. It involves thorough assessment, accurate diagnosis, strategic planning, effective implementation, and diligent evaluation. By meticulously following this step-by-step process, healthcare professionals play a crucial role in providing the best possible care and treatment for patients with asthma, enhancing their overall health and well-being.

01:19Respiratory Assessment: Purpose and Indications
Respiratory assessment is a cornerstone of nursing assessments, crucial for the early detection of patient deterioration. This evaluation transcends routine procedures, representing a critical skill nurses must master to ensure optimal patient care.
Objectives and Importance:
The primary goal of respiratory assessment is to evaluate patients at early risk of clinical deterioration. Since respiratory distress often precedes other signs of declining health, breathing patterns and sounds become a...

01:26COPD: Management Using Bronchodilators and Corticosteroids
Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...
