Summary
New-onset diabetes, especially with insulin deficiency, may signal pancreatic cancer. Early detection of pancreatic cancer in such cases can improve patient outcomes and survival rates.
Area of Science:
- Endocrinology
- Oncology
- Primary Care Medicine
Background:
- Diabetes mellitus is typically classified as type 1 (autoimmune insulin deficiency) or type 2 (insulin resistance).
- Other underlying causes of diabetes necessitate consideration in patients presenting with new-onset hyperglycemia.
- The association between pancreatic cancer and diabetes is recognized but underrepresented in primary care literature.
Observation:
- A 50-year-old male diagnosed with type 2 diabetes mellitus experienced persistent hyperglycemia despite treatment.
- Diagnostic workup revealed metastatic pancreatic cancer as the underlying cause.
Findings:
- New-onset diabetes with predominant insulin deficiency and no family history of type 2 diabetes should prompt suspicion for pancreatic cancer.
- Metastatic pancreatic cancer can manifest as new-onset diabetes mellitus.
Implications:
- Clinicians should consider pancreatic cancer in patients with new-onset diabetes, particularly those lacking typical type 2 diabetes features.
- Recognizing this association can lead to earlier pancreatic cancer detection and treatment.
- Improved early detection of pancreatic cancer offers opportunities for timely intervention and enhanced patient survival.

5.0K
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 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...

Overview
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

Hormones can be classified into three main types based on their chemical structures: steroids, peptides, and amines. Their actions are mediated by the specific receptors they bind to on target cells.

01:46Types of Selection
45.0K
Natural selection influences the frequencies of particular alleles and phenotypes within populations in several different ways. Primarily, natural selection can be directional, stabilizing, or disruptive. Directional selection favors one extreme trait and shifts the population towards that phenotype while selecting against individuals displaying alternate traits. Stabilizing selection favors an intermediate trait with a narrow range of variation. Deviation from the optimal phenotype towards an...

If the frequency distribution of a data set is more inclined towards smaller or larger values, the distribution is said to be skewed. If data values are skewed to the right, then the distribution is called positively skewed. Conversely, if the plot is skewed to the left, the distribution is called negatively skewed.
For instance, in the middle of a pandemic, the geographical distribution of vaccine coverage may be positively skewed towards populations in the global north countries. However,...
