Summary
Preterm infants
Area of Science:
- Neonatal dermatology
- Infant skin physiology
- Developmental biology
Background:
- Preterm infants possess immature skin, increasing susceptibility to skin issues.
- Postnatal skin development in preterm infants remains under-researched.
- Understanding skin changes is crucial for neonatal intensive care.
Purpose of the Study:
- To evaluate the temporal changes in skin water content in preterm infants.
- To correlate initial skin water content with gestational age.
- To determine when preterm infant skin reaches term-equivalent hydration.
Main Methods:
- Prospective observational study of 101 preterm infants in a neonatal intensive care unit.
- Skin water content measured using dielectric methods at 1.5mm depth across five regions.
- Measurements taken on postnatal days 1, 2, 3, 7, and weekly until 37 weeks corrected age.
Main Results:
- Initial skin water content on day 1 showed an inverse correlation with gestational age.
- Significant decrease in skin water content observed over time.
- Skin hydration levels normalized to term infant levels by 32-35 weeks corrected age.
Conclusions:
- Postnatal changes in skin water content are significant in preterm infants.
- Skin hydration in preterm infants matures and reaches term-equivalent levels by approximately 32-35 weeks corrected age.
- Corrected age is a key factor in the postnatal maturation of preterm infant skin water content.

01:14Changes in Skin Color: Clinical Perspectives
4.2K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

5.2K
Life's biochemical processes occur within aqueous solutions. Solutes are substances that are dissolved within these solutions. The human body contains a variety of solutes, which can differ across various body parts. These can encompass proteins—such as those responsible for clotting and carbohydrate transport—as well as electrolytes. In medicine, an electrolyte is often described as a mineral ion derived from a salt possessing an electric charge. Examples include sodium ions...

01:28Development of the Oral Microbiota
38
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...

01:57Adaptations that Reduce Water Loss
28.9K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

01:30Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from...

01:29Disorder of Water Balance
2.8K
Water balance disorders are medical conditions that occur when there is a deviation from the body's water volume or osmolarity, disrupting normal homeostasis and leading todehydration, hypotonic hydration, hyperhydration, edema, or water intoxication.
Dehydration
Dehydration occurs when the body loses fluids (particularly water).
Causes:
The major causes of dehydration include excessive sweating, fever, vomiting, diarrhea, and diuresis.
Signs and Symptoms:
