Polygenic Traits01:18

Polygenic Traits

66.2K
When more than one gene is responsible for a given phenotype, the trait is considered polygenic. Human height is a polygenic trait. Studies have uncovered hundreds of loci that influence height, and there are believed to be many more. Due to the high number of genes involved, as well as environmental and nutritional factors, height varies significantly within a given population. The distribution of height forms a bell-shaped curve, with relatively few individuals in the population at the...

Factors affecting Blood pressure01:28

Factors affecting Blood pressure

3.4K
Several physiological and lifestyle factors influence blood pressure (BP). Understanding these factors is crucial as they are significant in patient education and blood pressure management.

Hormonal Regulation01:33

Hormonal Regulation

33.6K
The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.

Hypertension and Regulation of Blood Pressure01:18

Hypertension and Regulation of Blood Pressure

2.2K
Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...

Diabetes Mellitus: Type 2 and Gestational01:22

Diabetes Mellitus: Type 2 and Gestational

2.6K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Pathophysiology of Diabetes01:20

Pathophysiology of Diabetes

1.1K
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Area of Science:

  • Obstetrics and Gynecology
  • Genetics
  • Computational Biology

Background:

  • Preeclampsia and gestational hypertensive disorders (GHD) are significant pregnancy complications impacting maternal and offspring health.
  • Known risk factors include high BMI, advanced maternal age, and pre-existing conditions, but risk assessment requires refinement for early identification and intervention.

Purpose of the Study:

  • To develop and validate a machine learning-based risk score for early GHD screening.
  • To investigate the relationship between GHD and genetically constructed anthropometric measures and biomarkers.
  • To confirm BMI as a risk factor for GHD.

Main Methods:

  • Utilized a case-control genetics dataset to develop a machine learning risk score.
  • Analyzed genetic data to construct anthropometric measures and biomarkers.
  • Integrated the risk score with traditional risk factors and medical history for GHD risk assessment.

Main Results:

  • A machine learning-derived risk score effectively serves as an early screening test for GHD.
  • Confirmed the association between high BMI and increased GHD risk.
  • Identified potential genetic factors and biomarkers linked to GHD.

Conclusions:

  • A polygenic risk score, alongside clinical data, can identify women at high risk for GHD.
  • This facilitates patient stratification for targeted monitoring and preventative strategies.
  • Early screening improves management of GHD, mitigating risks for mother and child.
