Insights

Extended breastfeeding, over 12 months, significantly lowers common childhood infections like otitis media and gastroenteritis. This protective effect of breast milk is evident throughout the first five years of life.

Area of Science:

  • Pediatrics
  • Public Health
  • Epidemiology

Background:

  • Previous studies indicate breastfeeding duration reduces infectious diseases during infancy.
  • The long-term impact of breastfeeding on childhood infections requires further investigation.

Purpose of the Study:

  • To examine the association between breastfeeding duration and common infectious diseases up to age five.
  • To demonstrate the sustained protective effects of breast milk beyond the breastfeeding period.

Main Methods:

  • A 5-year prospective-cohort study involving 411 infants born in Rize, Turkey (2011-2012).
  • Mothers underwent 11 interviews during the study period.
  • Infants were categorized into two groups: breastfed >12 months and <12 months.
  • Investigated infections included acute otitis media, acute gastroenteritis, acute respiratory tract infections, and acute urinary system infections.

Main Results:

  • 193 (71.5%) infants were breastfed for over 12 months; 77 (28.5%) for less than 12 months.
  • Infants breastfed >12 months experienced significantly fewer cases of acute otitis media and acute gastroenteritis (p <0.05) over the 5-year period.
  • No significant difference was noted for respiratory or urinary tract infections between groups.

Conclusions:

  • Breastfeeding duration exceeding 12 months is associated with a significant reduction in otitis media and gastroenteritis in children up to five years of age.
  • Prolonged breastfeeding offers lasting protection against specific common childhood infections.

Common Ion Effect03:24

Common Ion Effect

Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Châtelier’s principle. Consider the dissolution of silver iodide:

5-Number Summary

In a dataset, the 5-number summary includes the minimum data value, the data value of the first quartile, the median data value or data value of the second quartile, the data value of the third quartile, and the maximum data value. These 5 data values can be visualized as a box and whisker plot.
In a box plot, the minimum and maximum data values represent the lower and upper whiskers in the graph, and the median is designated as the center of the box in the chart. The first quartile and third...

Common Respiratory Disorders01:31

Common Respiratory Disorders

Respiratory disorders, a prevalent health concern globally, are generally divided into two primary categories: upper and lower respiratory tract disorders. The categorization is based on the area of the respiratory system they affect.
Upper respiratory disorders impact the airways above the vocal cords, encompassing areas like the nose, sinuses, and throat. Various conditions fall under this category, including the common cold and allergic rhinitis. These disorders can stem from several causes,...

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

Mass Analyzers: Common Types01:19

Mass Analyzers: Common Types

The quadrupole mass analyzer consists of four cylindrical metal rods arranged in a diamond carrying a DC voltage and a radio-frequency AC voltage. The motion of ions through the quadrupole depends on the field strength, causing only ions of a certain m/z to resonate successfully and strike the detector at a given field strength. Though the transmission rate for these analyzers is high, the exact elemental composition of the sample is not determined because of low resolution; however, they are...

Common Leveling Mistakes and Errors

A survey team is tasked with determining the elevation difference between points Point A and Point B, separated by uneven terrain. They use a leveling instrument and a leveling rod.Common MistakesMisreading the Rod: During a backsight reading at Point A, the instrumentman observes the rod partially obscured by tall grass. Instead of reading 1.135 m, they mistakenly record 1.735 m due to the misalignment of the crosshair with the wrong graduation. This error adds 0.600 m to all subsequent...
