Diabetes: Management and Pharmacotherapy01:15

Diabetes: Management and Pharmacotherapy

1.5K
The therapy for diabetes aims to alleviate hyperglycemia-related symptoms, prevent acute metabolic decompensation, and reduce chronic end-organ complications. Glycemic control is evaluated through short-term (self-monitoring, continuous glucose monitoring) and long-term (A1c, fructosamine) metrics, enabling near real-time tracking of blood glucose levels and reflecting glycemic control over specific time frames.
Insulin remains the cornerstone of treatment for most patients with type 1 and many...

Diabetes Mellitus: Type 2 and Gestational

5.8K
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...

Diabetes Mellitus: Overview and Type I Subtype

6.3K
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...

Hypoglycemia and Glucagon01:15

Hypoglycemia and Glucagon

1.3K
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...

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...

Nursing management is essential for preventing complications, maintaining stability, and improving patients' quality of life in chronic kidney disease (CKD). By using a structured approach, nurses help slow CKD progression and support effective patient care​.1. Comprehensive patient assessmentEffective management begins with nurses reviewing the patient’s medical history, and identifying key risk factors like diabetes, hypertension, and nephrotoxic drug use. Nurses assess signs of...

Summary

A single educational session significantly boosted intermittently scanned continuous glucose monitoring (isCGM) use in type 1 diabetes (T1D) patients. This improved daily scan frequency and time in range (TIR), enhancing glycemic control.

Area of Science:

  • Endocrinology
  • Diabetes Management
  • Behavioral Science

Background:

  • Low scan frequency is a key limitation in maximizing intermittently scanned continuous glucose monitoring (isCGM) benefits.
  • Higher daily scan frequency in isCGM use is directly correlated with improved glycemic control.

Purpose of the Study:

  • To assess the impact of a nurse-led educational intervention on isCGM scan frequency and behavioral changes.
  • To evaluate the intervention's effect on adults with type 1 diabetes (T1D) exhibiting low isCGM scanning habits.

Main Methods:

  • A 12-week quasi-experimental study involving adults with T1D using isCGM and low scan frequency.
  • Participants received a single, individualized, nurse-led education session focused on increasing scan frequency and self-management engagement.

Main Results:

  • Mean daily scan frequency increased from 3.1 to 6.1 scans/day post-intervention.
  • An 8.0% improvement in time in range (TIR) was observed, correlating positively with scan frequency.
  • Each additional daily scan was associated with a 0.51% increase in TIR.

Conclusions:

  • A single, targeted educational intervention effectively enhances isCGM adherence and glycemic control in T1D adults with low adherence.
  • This strategy proves valuable and practical for routine clinical diabetes care.
