Continuous Renal Replacement Therapy01:30

Continuous Renal Replacement Therapy

647
Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...

Metabolism of Chemolithotrophs01:15

Metabolism of Chemolithotrophs

669
Chemolithotrophs are microorganisms that obtain energy by oxidizing inorganic molecules such as hydrogen gas (H₂), ammonia (NH₃), reduced sulfur compounds (H₂S, S²⁻), and ferrous iron (Fe²⁺). Unlike heterotrophic organisms that rely on organic carbon, chemolithotrophs transfer electrons from these inorganic donors to the electron transport chain (ETC), generating a proton motive force (PMF) that drives ATP synthesis through oxidative phosphorylation.

Introduction to Metabolism

2.5K
Metabolism encompasses all biochemical reactions in a living organism, facilitating both the breakdown and synthesis of biomolecules. These metabolic processes are categorized into catabolic and anabolic pathways, which operate in a coordinated manner to ensure energy balance and cellular function.Catabolic Pathways and Energy ReleaseCatabolic pathways involve the breakdown of complex macromolecules such as carbohydrates, lipids, and proteins into smaller structures like monosaccharides, fatty...

Regulation of Metabolism01:19

Regulation of Metabolism

11.3K
Cellular needs and conditions vary from cell to cell and change within individual cells over time. For example, the required enzymes and energetic demands of stomach cells are different from those of fat storage cells, skin cells, blood cells, and nerve cells. Furthermore, a digestive cell works much harder to process and break down nutrients during the time that closely follows a meal compared with many hours after a meal. As these cellular demands and conditions vary, so do the amounts and...

Overview of Metabolism

Living cells constantly carry out various chemical reactions which are necessary for their proper functioning. These reactions are interlinked to one another via multiple pathways. The collection of these chemical reactions is known as metabolism.
Plant Metabolism
Sunlight, the primary source of energy in plants, is first absorbed by the chlorophyll pigments present in their leaves. Plants then use this energy to carry out photosynthesis, where water is oxidized into oxygen and carbon dioxide...

Metabolic States of the Body: The Absorptive State01:25

Metabolic States of the Body: The Absorptive State

1.3K
During the absorptive state, which lasts approximately four hours after a meal, the body absorbs nutrients from the gastrointestinal tract. The carbohydrates, proteins, and lipids we consume are broken down into monosaccharides, amino acids, and free fatty acids for absorption. While carbohydrates and proteins are absorbed as-is, lipids are absorbed in their broken-down forms and then re-esterified into triglycerides within enterocytes before being packaged into chylomicrons. These absorbed...

Area of Science:

  • Critical Care Medicine
  • Metabolic Physiology
  • Endocrinology

Background:

  • Critical illness presents complex metabolic derangements.
  • Existing intensive care unit (ICU) protocols may not fully address metabolic recovery.
  • Chronic critical illness poses a significant challenge in patient management.

Purpose of the Study:

  • To introduce and define intensive metabolic support as a novel critical care strategy.
  • To outline the components and timing of intensive metabolic support.
  • To emphasize the potential benefits for patient outcomes and mortality.

Main Methods:

  • Literature search of MEDLINE (1995-2008) for relevant studies.
  • Focus on metabolic stages, intensive insulin therapy, and metabolic support in ICUs.
  • Synthesis and summarization of clinical data from selected studies.

Main Results:

  • Intensive metabolic support is a three-component model: metabolic control (including intensive insulin therapy), early nutrition, and nutritional pharmacology.
  • This approach aims to prevent allostatic overload and chronic critical illness.
  • Initiation upon ICU arrival and continuation through recovery is recommended for improved outcomes and mortality reduction.

Conclusions:

  • Intensive metabolic support should be integral to critical care treatment strategies.
  • Requires enhanced collaboration between endocrinologists and intensivists.
  • Further research is needed to validate and implement this protocol for reducing chronic critical illness.
