Insights

High body mass index (BMI) was not linked to disease severity in children with sickle cell disease. However, obesity was more common in females and those with HbSC, indicating a need for further research.

Area of Science:

  • Pediatrics
  • Hematology
  • Public Health

Background:

  • Sickle cell disease (SCD) is a genetic blood disorder with varying clinical severity.
  • High body mass index (BMI) is a growing concern in pediatric populations, but its impact on SCD is not well understood.

Purpose of the Study:

  • To determine the prevalence of high BMI in children with sickle cell disease.
  • To investigate the correlation between high BMI and indicators of SCD severity.

Main Methods:

  • A retrospective chart review was conducted at a single tertiary pediatric clinic.
  • Data from 385 children (ages 2-18) with sickle cell disease (HbSS and HbSC genotypes) were analyzed.
  • Included data: BMI, laboratory results, hospital admission rates, and obstructive sleep apnoea (OSA) status.

Main Results:

  • 17% of children with SCD were overweight or obese.
  • Obesity prevalence was significantly higher in children with HbSC genotype (25%) compared to HbSS genotype (13%).
  • No significant correlation was found between high BMI and OSA, hospital admissions, fetal hemoglobin levels, or lactate dehydrogenase levels.

Conclusions:

  • High BMI is not associated with increased disease severity in this cohort of children with sickle cell disease.
  • Obesity is more prevalent in females and those with the HbSC genotype.
  • Further prospective studies are recommended to explore the long-term effects of BMI on SCD outcomes.

Reduced Mass Coordinates: Isolated Two-body Problem

In classical mechanics, the two-body problem is one of the fundamental problems describing the motion of two interacting bodies under gravity or any other central force. When considering the motion of two bodies, one of the most important concepts is the reduced mass coordinates, a quantity that allows the two-body problem to be solved like a single-body problem. In these circumstances, it is assumed that a single body with reduced mass revolves around another body fixed in a position with an...

Neurons: The Cell Body and the Dendrites

A typical nerve cell comprises three main components: the cell body, dendrites, and the axon. The cell body, also known as the soma or perikaryon, serves as the central biosynthetic hub housing a nucleus surrounded by cytoplasm containing organelles commonly found in most cells. Notably, Nissl bodies, clusters of the rough endoplasmic reticulum and free ribosomes responsible for protein synthesis, are distinctive features of the neuronal cell body. As neurons age, aggregates of a brown pigment...

Atomic Mass01:52

Atomic Mass

Atoms — and the protons, neutrons, and electrons that compose them — are extremely small. For example, a carbon atom weighs less than 2 × 10−23 g. When describing the properties of tiny objects such as atoms, we use appropriately small units of measure, such as the atomic mass unit (amu). The amu was originally defined based on hydrogen, the lightest element, then later in terms of oxygen. Since 1961, it has been defined with regard to the most abundant isotope of carbon, atoms of which...

Molar Mass01:54

Molar Mass

The identity of a substance is defined not only by the types of atoms or ions it contains but by the quantity of each type of atom or ion. For example, water, H2O, and hydrogen peroxide, H2O2, are alike in that their respective molecules are composed of hydrogen and oxygen atoms. However, because a hydrogen peroxide molecule contains two oxygen atoms, as opposed to the water molecule, which has only one, the two substances exhibit very different properties.

EPS and iPS Cells in Disease Research

Embryonic and induced pluripotent stem cells are excellent models for disease research because of their ability to self-renew and differentiate into most cell types. Somatic cells from a patient are isolated and reprogrammed into induced pluripotent stem cells or iPSCs. These iPSCs are later differentiated into the desired cell type, which mirrors the diseased cell of the patient. In this way, disease models have been created for investigating diseases such as Down syndrome, type I diabetes,...

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...
