Overview of Carbohydrate Metabolism01:19

Overview of Carbohydrate Metabolism

3.2K
Carbohydrate metabolism is a fundamental biochemical process that ensures a constant supply of energy to living cells. The most important carbohydrate is glucose, which can be broken down via glycolysis to enter into the Krebs cycle and eventually lead to the production of ATP through oxidative phosphorylation.
Glucose transport into cells is facilitated by a family of transport proteins called GLUT (Glucose Transporters). GLUT4 is the primary glucose transporter for insulin-stimulated glucose...

Metabolic Rate01:25

Metabolic Rate

1.1K
The human body is a powerhouse of energy, with every cell performing numerous functions that require energy. This energy production and consumption is measured by the metabolic rate, which quantifies the total heat generated by all the body's chemical reactions and mechanical work. This measurement helps to determine the rate of kilocalorie (kcal) consumption needed to fuel all ongoing activities.
The Basal Metabolic Rate (BMR) measures the energy expended at rest.
Several factors influence...

Metabolic States of the Body: Fasting and Starvation01:24

Metabolic States of the Body: Fasting and Starvation

2.6K
During the initial hours of fasting, the body uses up its glycogen stores as an energy source. Once these glycogen reserves are depleted, the body begins breaking down stored triglycerides and structural proteins. During this stage, glycerol becomes a key substrate for gluconeogenesis, while free fatty acids undergo beta-oxidation to provide energy for tissues, such as skeletal muscle. In the fasting state, the body spares protein breakdown as much as possible to conserve muscle and structural...

Metabolic States of the Body: The Postabsorptive State01:18

Metabolic States of the Body: The Postabsorptive State

1.2K
The postabsorptive state usually starts about four hours after a meal and lasts until the next meal is eaten. During this time, the digestive system stops absorbing nutrients, and the body uses stored energy reserves to maintain stable blood glucose levels.
Initially, glycogen stored in the liver is broken down to release glucose into the bloodstream, while glycogen in the muscles is broken down to supply glucose for energy directly within the muscle cells. As glycogen stores diminish,...

Muscle Recovery and Fatigue01:24

Muscle Recovery and Fatigue

3.9K
Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective...

Pharmacokinetics in Obese Patients: Drug Metabolism and Excretion01:20

Pharmacokinetics in Obese Patients: Drug Metabolism and Excretion

153
Drug metabolism, a critical process in the liver, involves two primary phases: Phase I reactions and Phase II conjugation. Obesity introduces significant alterations in this metabolic process, primarily due to fatty infiltration of the liver, leading to conditions such as nonalcoholic fatty liver disease (NAFLD). This condition can modify the activities of both Phase I and II enzymes, impacting how drugs are metabolized in obese patients.Phase I metabolism sees variable effects across...

Area of Science:

  • Infectious Diseases
  • Metabolic Health
  • Public Health

Background:

  • Post-acute sequelae of SARS-CoV-2 infection (COVID-19) are a growing public health concern.
  • Limited data exist on metabolic disorder risk following COVID-19 in young, healthy populations.
  • This study investigates metabolic risks in U.S. active-duty service members (ADSM).

Purpose of the Study:

  • To quantify the risk of new-onset metabolic disorders after SARS-CoV-2 infection.
  • To assess incident diagnoses of type 2 diabetes mellitus (T2DM), hypertension (HTN), hyperlipidemia (HLD), metabolic dysfunction-associated steatotic liver disease (MASLD), and metabolic syndrome (MetS).
  • To evaluate these risks in a young, healthy ADSM cohort.

Main Methods:

  • Propensity score-matched cohort study using U.S. Military Health System data (July 2020 - June 2021).
  • 103,789 COVID-19 exposed ADSM (aged 18-65) compared with 207,578 controls (1:2 matching).
  • Cox proportional hazards models assessed outcomes within one year, controlling for obesity.

Main Results:

  • COVID-19 infection was associated with significantly increased hazards for incident hypertension (aHR 1.09) and hyperlipidemia (aHR 1.30).
  • A significant increased hazard was observed for metabolic dysfunction-associated steatotic liver disease (aHR 1.36).
  • No significant increased risk for type 2 diabetes mellitus or metabolic syndrome was found.

Conclusions:

  • COVID-19 infection is linked to a significantly increased risk of developing hypertension, hyperlipidemia, and MASLD.
  • These findings underscore potential long-term metabolic consequences in young, healthy individuals post-COVID-19.
  • Further research is warranted to understand the mechanisms and long-term implications.
