Bone Disorders01:29

Bone Disorders

3.5K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Diabetes Mellitus: Type 2 and Gestational

2.3K
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...

Carbohydrate Metabolism01:36

Carbohydrate Metabolism

11.0K
Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

Diabetes: Symptoms, Diagnosis, and Complications

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Role of Vitamins in Maintaining Bone Health01:25

Role of Vitamins in Maintaining Bone Health

3.2K
The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Area of Science:

  • Endocrinology
  • Orthopedics
  • Gerontology

Background:

  • Type 2 diabetes mellitus (T2DM) is linked to increased skeletal fragility and fracture risk.
  • Patients with T2DM often have normal bone mineral density (BMD) on dual-energy x-ray absorptiometry (DXA), masking underlying bone issues.
  • Diabetic osteopathy involves changes in bone architecture, like cortical porosity, not detected by routine DXA.

Purpose of the Study:

  • To discuss the clinical burden and presentation of skeletal disease in T2DM.
  • To highlight limitations of current fracture risk assessment in T2DM.
  • To propose an improved approach for managing skeletal health in T2DM.

Main Methods:

  • Review of the association between T2DM and skeletal fragility.
  • Discussion of limitations of dual-energy x-ray absorptiometry (DXA) for assessing bone health in T2DM.
  • Exploration of alternative imaging techniques like quantitative computed tomography and trabecular bone score.
  • Analysis of current fracture risk calculators and their underestimation in T2DM.
  • Consideration of antidiabetic medications' effects on bone health.

Main Results:

  • T2DM patients face a higher fracture risk, often not predicted by standard BMD measurements.
  • Conventional fracture risk calculators underestimate risk in T2DM due to reliance on BMD.
  • Advanced imaging can reveal bone architectural changes indicative of fragility in T2DM.
  • Antidiabetic drug choice impacts skeletal health and fracture risk.

Conclusions:

  • Managing skeletal health in T2DM requires lower BMD thresholds for treatment initiation.
  • Adjusted fracture risk calculators and consideration of metabolic/non-skeletal factors are crucial.
  • Alternative imaging modalities may aid in identifying high-risk T2DM patients.
  • Treatment decisions for T2DM should account for bone health impacts.
