Psychoneuroimmunology: Diabetes and Cancer

528
Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

mTOR Signaling and Cancer Progression

3.6K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

Inflammatory Bowel Disease II: Crohn's Disease

1.6K
Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Cancer Prevention

6.5K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.
Some...

Regulation of Food Intake01:30

Regulation of Food Intake

2.8K
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Summary
This summary is machine-generated.

Systemic inflammation in advanced cancer patients significantly reduces energy and protein intake. C-reactive protein (CRP) levels can identify individuals needing enhanced nutritional support to combat undernutrition.

Area of Science:

  • Oncology
  • Nutrition Science
  • Inflammation Research

Background:

  • Undernutrition and cachexia are prevalent in advanced cancer, often driven by systemic inflammation.
  • While inflammation correlates with poor prognosis and weight loss, its specific impact on food intake is not fully understood.
  • Investigating inflammation's role in appetite regulation is crucial for cancer patient care.

Purpose of the Study:

  • To investigate the relationship between systemic inflammation and energy and protein consumption over time in advanced cancer patients.
  • To determine if inflammatory markers predict changes in dietary intake.
  • To identify potential targets for nutritional interventions in oncology.

Main Methods:

  • 170 advanced cancer patients from the Palliative Radiotherapy and Inflammation Study were analyzed.
  • Nutritional status assessed via PG-SGA SF; dietary intake via 24-hour recalls.
  • Systemic inflammation defined by C-reactive protein (CRP) > 10 mg/L; analyzed using mixed linear models.

Main Results:

  • Over half the patients (51%) exhibited systemic inflammation (CRP >10 mg/L).
  • Inflammation was linked to significantly lower energy intake (-3.6 kcal/kg) and protein intake (-0.25 g/kg).
  • Patients with inflammation showed higher rates of undernutrition and reduced survival.

Conclusions:

  • Systemic inflammation is associated with substantial reductions in energy and protein intake in advanced cancer.
  • Elevated CRP levels may indicate patients who require more intensive nutritional support.
  • Targeting inflammation could be a key strategy to improve nutritional status and outcomes in cancer patients.
