Summary
Severe bronchiolitis in infants incurs high medical costs, particularly in tropical middle-income nations. This study identified respiratory syncytial virus and cigarette smoke exposure as key risk factors for severe infant bronchiolitis.
Area of Science:
- Pediatrics
- Infectious Diseases
- Public Health
Background:
- Severe bronchiolitis in infants presents a significant economic challenge, especially in tropical, middle-income countries.
- Identifying risk factors is crucial for developing targeted prevention and intervention strategies.
Purpose of the Study:
- To investigate the risk factors associated with severe bronchiolitis in infants admitted to Rionegro, Colombia.
- To inform public health initiatives and reduce the economic burden of infant bronchiolitis.
Main Methods:
- Retrospective cohort study design.
- Inclusion of infants under two years old admitted with bronchiolitis.
- Log-binomial regression analysis to estimate prevalence ratios.
Main Results:
- A total of 417 infants were included; 72.12% (300) had severe bronchiolitis.
- Respiratory syncytial virus (RSV) infection was identified as an independent predictor.
- Current exposure to cigarette smoke was also a significant independent predictor of severe bronchiolitis.
Conclusions:
- RSV infection and environmental tobacco smoke exposure are critical risk factors for severe infant bronchiolitis.
- These findings highlight the need for enhanced RSV prevention and public health campaigns against smoking in households with infants.

01:17Pulmonary Cycle: Exhalation
2.3K
In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

01:29Pulmonary Tuberculosis I
472
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

3.0K
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...

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...

3.2K
Chronic Obstructive Pulmonary Disease (COPD) is a long-lasting respiratory condition requiring continuous attention and care. It is a progressive lung disease that leads to breathing challenges due to airflow obstruction. It manifests as persistent respiratory symptoms and restricted airflow resulting from abnormalities in the airways and alveoli, usually due to long-term exposure to harmful particles or gases. COPD mainly consists of two primary conditions: emphysema and chronic bronchitis.

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...
