Summary
Total gastrectomy leads to significant bone disorder in patients and rats, resembling osteomalacia. Malabsorption of vitamin D and calcium due to poor intake and diarrhea are likely causes.
Area of Science:
- Gastroenterology and Bone Metabolism
- Surgical Outcomes and Nutritional Deficiencies
Context:
- Total gastrectomy, a major surgical procedure, can lead to significant post-operative complications.
- Bone health is a critical concern following extensive gastrointestinal surgery.
Purpose:
- To investigate the prevalence and characteristics of bone disorder after total gastrectomy.
- To explore the underlying mechanisms contributing to bone metabolism disturbances post-gastrectomy.
Summary:
- Clinical study: 63% of patients exhibited bone abnormalities, 52% hypocalcemia, and 47% elevated alkaline phosphatase (A1-P). Calcium infusion tests suggested osteomalacia.
- Animal study: Total gastrectomy in rats showed decreased bone density, reduced food intake, lower serum calcium and vitamin D, increased fecal lipids, and impaired intestinal calcium absorption.
- Findings indicate a progressive bone deterioration over time post-surgery, with malabsorption of vitamin D and calcium as primary etiological factors.
Impact:
- Highlights the significant risk of osteomalacia following total gastrectomy.
- Underscores the importance of monitoring bone metabolism and nutritional status in post-gastrectomy patients.
- Suggests potential therapeutic targets focusing on calcium and vitamin D supplementation and management of malabsorption.

Hypertension II: Pathophysiology
915
Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...

Bone Disorders
5.3K
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...

Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...

Pathophysiology of Diabetes
3.5K
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,...

Pathophysiology of Vomiting
3.0K
Vomiting is a complex physiological response to expel harmful or irritating substances from the body. It's a defensive mechanism triggered by stimuli like poisons, microbial toxins, cytotoxic drugs, and mechanical abdominal distension. The process is centrally coordinated by the vomiting (or emetic) center located in the medulla of the brainstem. This area, rich in muscarinic M1, histamine H1, neurokinin 1 (NK1), and serotonin 5-HT3 receptors, coordinates the act of vomiting through...
