Neurogenesis and Regeneration of Nervous Tissue01:15

Neurogenesis and Regeneration of Nervous Tissue

966
In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

Muscle Recovery and Fatigue01:24

Muscle Recovery and Fatigue

2.4K
Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective...

Anorexia Nervosa01:28

Anorexia Nervosa

179
Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses.

Bulimia Nervosa01:30

Bulimia Nervosa

183
Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...

Whole Body Regeneration01:33

Whole Body Regeneration

3.4K
Regeneration is the process of restoring injured or lost tissues, organs, or body parts. While simpler organisms generally show greater ability to regenerate their whole body, few complex animals show similarly exceptional regeneration. For example, planarian flatworms have a unique regenerative potential making them a popular study organism among biologists to understand the mechanisms of whole body regeneration. Other organisms, such as hydra, also show extreme regeneration potential;...

Binge Eating Disorders01:23

Binge Eating Disorders

160
Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...

Summary

Children’s neurodevelopment recovery parallels their physical recovery from malnutrition after acute illness. Stunting significantly impacts this recovery, highlighting the need for integrated care approaches.

Area of Science:

  • Child Health
  • Neurodevelopmental Outcomes
  • Malnutrition Research

Background:

  • Acute illness and malnutrition are leading causes of hospitalization for children in low- and middle-income countries.
  • Understanding the link between malnutrition recovery and child development is crucial for improving long-term health outcomes.

Purpose of the Study:

  • To investigate the association between wasting recovery trajectories and neurodevelopmental outcomes in young children after hospitalization for acute illness.
  • To identify factors influencing neurodevelopmental recovery in children recovering from acute illness and malnutrition.

Main Methods:

  • Prospective observational cohort study of children aged 2–23 months in Uganda, Malawi, and Pakistan.
  • Wasting recovery trajectories were determined by changes in mid-upper arm circumference-for-age z-score.
  • Neurodevelopment was assessed using the Malawi Developmental Assessment Tool (MDAT) development-for-age z-score (DAZ) at discharge and 6 months post-hospitalization.

Main Results:

  • Four wasting recovery trajectories were identified: high-stable, wasted-improved, severely wasted-greatly improved, and severely wasted-not improved.
  • Children with severe wasting who greatly improved showed a steep positive neurodevelopmental recovery slope, especially those also affected by stunting.
  • While children with wasting recovery showed no difference in neurodevelopmental scores compared to community children after 6 months, those who did not recover from wasting had significant developmental delays.

Conclusions:

  • Neurodevelopmental recovery in children convalescing from acute illness occurs in parallel with physical recovery from wasting.
  • Stunting significantly influences the trajectory of neurodevelopmental recovery in children experiencing malnutrition.
  • Early and effective management of wasting and stunting is critical for optimizing neurodevelopmental outcomes in children post-hospitalization.
