Insights

Recurrent wheezing affects over a quarter of infants in Buenos Aires. Key risk factors include frequent colds, early onset, and maternal smoking during pregnancy, some of which are preventable.

Area of Science:

  • Pediatrics
  • Epidemiology
  • Respiratory Medicine

Background:

  • Bronchial obstruction episodes in early childhood are a common pediatric concern.
  • Recurrent wheezing in infants presents a significant public health challenge.
  • Understanding prevalence and associated factors is crucial for early intervention.

Purpose of the Study:

  • To determine the prevalence of recurrent wheezing in infants in Buenos Aires City.
  • To identify risk factors associated with wheezing and recurrent wheezing in this population.

Main Methods:

  • A cross-sectional study was conducted from 2011 to 2012.
  • Validated questionnaires were administered to parents of 1063 infants aged 12-15 months.
  • Statistical analyses included chi-squared tests, Fisher's test, and logistic regression.

Main Results:

  • The prevalence of recurrent wheezing (≥3 episodes) was 26.3%.
  • Associated risk factors included male gender, ≥6 colds in the first year, early cold onset (<4 months), pneumonia, and maternal smoking.
  • For recurrent wheezing, risk factors included ≥6 colds, early onset wheezing, and nocturnal wheezing.

Conclusions:

  • The prevalence of recurrent wheezing in Buenos Aires infants is notably high.
  • Several identified risk factors, such as maternal smoking and frequency of colds, are potentially preventable.
  • Further research and preventative strategies are warranted.

Prevalence and Incidence01:08

Prevalence and Incidence

In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

Air-entraining Agents01:27

Air-entraining Agents

Air-entraining agents improve the durability and workability of concrete in climates with frequent freezing and thawing. These agents prevent cracks by introducing small air bubbles into the mix, creating spaces accommodating water expansion when temperatures drop. The air-entraining agents lower the surface tension of water, forming stable, small air bubbles. This method is more effective than having accidental large voids, as the intentional, smaller, and evenly distributed air voids improve...

Transcription Factors02:16

Transcription Factors

Tissue-specific transcription factors contribute to diverse cellular functions in mammals. For example, the gene for beta globin, a major component of hemoglobin, is present in all cells of the body. However, it is only expressed in red blood cells because the transcription factors that can bind to the promoter sequences of the beta globin gene are only expressed in these cells. Tissue-specific transcription factors also ensure that mutations in these factors may impair only the function of...

Drug Dosing: Infants and Children01:29

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Effects of Air-entrainment in Concrete01:28

Effects of Air-entrainment in Concrete

Air entrainment in concrete significantly enhances the material's durability, especially in environments subjected to freeze-thaw cycles. Introducing small air bubbles into the concrete mix acts as internal voids that accommodate the expansion of water when it freezes, thereby alleviating internal stress and preventing structural cracks. This function is crucial in climates with significant freezing and thawing, as it protects the concrete from repeated stresses that could lead to premature...

Measurement of Air Content in Concrete01:23

Measurement of Air Content in Concrete

Air content measurement in concrete is critical for ensuring structural integrity and durability of concrete structures, especially in environments prone to severe weather conditions. Accurate air content analysis optimizes concrete's resistance to freeze-thaw cycles and enhances its workability and strength. Several methods are standardized under ASTM guidelines to measure the air content in fresh concrete, each suitable for different concrete types and conditions.
The pressure method,...
