Liver Histology01:27

Liver Histology

4.4K
The microscopic anatomy of the liver is a complex and intricate system that comprises numerous structural units known as liver lobules, each of which is comparable in size to a sesame seed. These hexagonal structures consist of plates of liver cells or hepatocytes, which are characterized by their versatility and abundance of cellular apparatus like rough and smooth ER, Golgi apparatus, peroxisomes, and mitochondria.
Hepatocytes perform a variety of essential functions. They secrete...

Liver Physiology

3.8K
The liver, an essential organ in the human body, performs over 200 vital functions that can be broadly categorized into metabolic, hematological, endocrine regulation, and bile production.
Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of  70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can...

Liver Regeneration

4.3K
The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are...

Cardiac Output II: Effect of Stroke Volume on Cardiac Output01:22

Cardiac Output II: Effect of Stroke Volume on Cardiac Output

3.4K
Cardiac output (CO), the amount of blood the heart pumps per minute, is a parameter in cardiovascular physiology determined by stroke volume and heart rate. Stroke volume, the amount of blood pushed from one of the ventricles per heartbeat, is influenced by preload, afterload, and contractility.
Preload
Preload refers to the initial elongation of the cardiac myocytes before contraction and is related to the volume of blood filling the heart at the end of diastole, or end-diastolic volume. The...

Acute Pharyngitis01:30

Acute Pharyngitis

4.2K
Introduction
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:

Cardiac Output I:Effect of Heart Rate on Cardiac Output

Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart...

Summary
This summary is machine-generated.

Hypoxic hepatitis (HH) is rare but significantly linked to poor neurological outcomes after cardiac arrest (CA). Acute liver failure (ALF) is common but not independently associated with worse outcomes in CA survivors.

Area of Science:

  • Cardiology
  • Hepatology
  • Critical Care Medicine

Background:

  • Limited data exist on hypoxic hepatitis (HH) and acute liver failure (ALF) following cardiac arrest (CA) resuscitation.
  • Understanding these liver complications is crucial for predicting patient outcomes.

Purpose of the Study:

  • To determine the incidence of HH and ALF in patients resuscitated from CA.
  • To investigate the association of HH and ALF with neurological outcomes and mortality.

Main Methods:

  • Retrospective study of 374 adult patients admitted after CA.
  • Data collected on CA characteristics, liver function markers (bilirubin, INR, aminotransferases).
  • ALF defined by bilirubin >1.2 mg/dL and INR ≥1.5; HH by aminotransferase >1000 IU/L. Neurological outcome assessed at 3 months (CPC score 3-5).

Main Results:

  • ALF occurred in 56% of patients, HH in 7%.
  • Patients with HH showed significantly higher mortality (89%) and unfavorable neurological outcomes (93%) compared to those with ALF alone or no liver issues.
  • HH, but not ALF, was an independent predictor of unfavorable neurological outcome (OR: 16.276).

Conclusions:

  • While ALF is frequent after CA, HH is a rare but severe complication.
  • HH is strongly associated with poor neurological outcomes in cardiac arrest survivors, unlike ALF.
