Vectors in a Hotter World
PodcastDX
This week we discuss vectors in a hotter world. Vector-borne diseases, which are transmitted by hematophagous arthropods such as mosquitoes, ticks, and sandflies, pose a significant burden on global public health. These diseases disproportionately affect populations in tropical and subtropical regions, where environmental conditions favor the survival and proliferation of vectors. Given that vectors are ectothermic organisms, their life cycles, reproduction, survival rates, and geographic distribution are heavily influenced by climate variables such as temperature, rainfall, and...

Intro to Ehlers Danlos Syndrome
PodcastDX
This week we discuss the basics about a topic several of our guests have spoken about- Ehlers Danlos Syndrome or EDS. Ehlers-Danlos syndrome is a group of inherited disorders that affect your connective tissues — primarily your skin, joints and blood vessel walls.

Food Is Medicine
PodcastDX
This week we discuss "Food is Medicine". The concept of "food is medicine" refers to the idea that certain foods and dietary patterns can play a significant role in promoting health, preventing disease, and managing chronic conditions. This concept is based on the notion that food is not only a source of energy and nutrients but also a powerful tool for influencing our physiological and biochemical processes. Access to affordable, nutritious food is crucial for good health, yet many Americans, particularly in under-resourced communities, face barriers. The result? A...

Tuberculosis Resurgence

Without such support, treatment adherence is more difficult. Since 2000, an estimated 66 million lives were saved through TB diagnosis and treatment. A total of 1.5 million people died from TB in 2020 (including 214 000 people with HIV). Worldwide, TB is the 13th leading...

Blood Clots
PodcastDX
This week we discuss blood clots A blood clot is a clump of blood that has changed from a liquid to a gel-like or semisolid state. Clotting is a necessary process that can excessive blood loss when you have a cut, for example. Thrombosis is when a blood clot and reduces blood flow. There are two types: Arterial thrombosis occurs when a blood clot forms in an artery. Venous thrombosis occurs when a blood clot forms in a vein.

info_outlineThis week we are talking about the Vagus Nerve. The vagus nerve (10th cranial nerve) is a critical part of the autonomic nervous system, responsible for regulating vital functions such as heart rate, digestion, and respiration. It extends from the brainstem (medulla oblongata) through the neck and chest to the abdomen, with motor and sensory fibers allowing communication between the brain and organs. The vagus nerve has two branches—left and right—which overlap in regulating autonomic functions.
Functions and Importance
-
Cardiac and Pulmonary Regulation: The left vagus nerve primarily innervates the heart, while the right focuses on the lungs, though both contribute to overall regulation.
-
Digestive System Support: It promotes digestion by increasing blood flow to the gastrointestinal tract and stimulating enzyme release.
-
Mental Health and Inflammation: The vagus nerve influences mood, anxiety, and stress by connecting to brain areas that regulate emotions. It also modulates inflammation, reducing pro-inflammatory molecules.
-
Enteric Nervous System Connection: Acting as a bridge between the brain and the "second brain" in the gut, the vagus nerve ensures coordination of digestive processes.
Vulnerability to Injury
Due to its extensive pathway, the vagus nerve is prone to injury from trauma, surgery, infections, tumors, or certain medical conditions. Common causes include:
-
Trauma: Accidents, falls, or sports injuries affecting the neck or chest.
-
Surgical Complications: Procedures in the neck, chest, or abdomen can unintentionally damage the nerve.
-
Medical Conditions: Disorders such as gastric ulcers, reflux, or tumors may affect the nerve. Infections like Lyme disease or meningitis are also potential causes.
-
Idiopathic Cases: Sometimes, the cause of vagus nerve injury remains unknown, requiring further investigation.
Symptoms of Vagus Nerve Injury
Injury symptoms depend on the severity and location of damage and may include:
-
Cardiovascular: Rapid or irregular heartbeat, blood pressure changes.
-
Digestive: Bloating, constipation, diarrhea, or difficulty swallowing.
-
Voice and Throat: Hoarseness, voice changes.
-
General: Anxiety, depression, or excessive sweating.
Diagnosis and Management
Diagnosing vagus nerve damage involves imaging, nerve conduction studies, and blood tests to assess functionality. Early detection is crucial for effective management and preventing complications. Prompt medical intervention can improve symptoms and enhance quality of life.
Understanding the vagus nerve’s anatomy and functions underscores its significance in maintaining overall health, aiding healthcare professionals in diagnosing and addressing related dysfunctions.
