Ascites01:19

Ascites

DefinitionAscites is the buildup of fluid inside the peritoneal cavity. It occurs when fluid moves out of the vascular system faster than the peritoneal lymphatics can remove it. This fluid shift is most commonly seen in liver cirrhosis but can also appear in several other systemic disorders.EtiologyCirrhosis remains the leading cause of ascites. Other conditions that can contribute include:Heart failureConstrictive pericarditisAbdominal cancersNephrotic syndromeSevere protein–calorie...
Cholecystitis01:20

Cholecystitis

Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...

Acute Pancreatitis II: Pathophysiology

The pathophysiology of acute pancreatitis centers on injury to pancreatic acinar cells, which initiates a cascade of harmful intracellular events.This injury leads to premature activation of trypsinogen to trypsin in the pancreas. Trypsin then activates other digestive enzymes, such as chymotrypsin, elastase, and phospholipase A2, which begin breaking down pancreatic tissue. The resulting autodigestion causes local inflammation, tissue swelling, hemorrhage, and fat necrosis.Injured acinar cells...

Acute Pancreatitis II: Clinical Manifestations and Management

Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...
Acute Pancreatitis I: Introduction01:25

Acute Pancreatitis I: Introduction

Acute pancreatitis is the sudden inflammation of the pancreas caused by the early activation of digestive enzymes, leading to the autodigestion of pancreatic tissue. This results in local inflammation and, in severe cases, systemic complications.EtiologyUnderstanding the underlying causes is crucial, as identifying the etiology guides treatment and anticipates complications. Acute pancreatitis can be triggered by various factors, typically grouped into the following clinical categories.Biliary...
Acute Pancreatitis I: Introduction01:27

Acute Pancreatitis I: Introduction

Pancreatitis is inflammation of the pancreas, an organ located behind the stomach. It can be either acute or chronic.
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:

Summary

Ascites in broiler chickens, a metabolic disease, is influenced by genetics and diet. Managing growth rate through feed or light restriction can mitigate ascites incidence.

Area of Science:

  • Animal Science
  • Avian Health
  • Genetics

Background:

  • Intensive selection in broiler chickens prioritizes productive traits, necessitating optimal management.
  • Suboptimal management of highly productive broilers can lead to inefficient production and metabolic diseases like ascites.
  • Ascites in broilers is multifactorial, with significant diet, environmental, and genetic interactions.

Purpose of the Study:

  • To investigate the multifactorial causes of ascites syndrome in broiler chickens.
  • To explore the role of genetic and environmental factors, particularly diet, in ascites development.
  • To identify practical management strategies for reducing ascites incidence.

Main Methods:

  • Analysis of heritability estimates for ascites-related traits, including maternal genetic effects.
  • Examination of the relationship between rapid growth rates, oxygen demand, and ascites.
  • Evaluation of the impact of early-age feed/nutrient restriction and light restriction on growth and ascites.

Main Results:

  • Direct and maternal genetic effects significantly contribute to ascites susceptibility.
  • An imbalance between oxygen supply and demand, driven by rapid growth, is a primary cause of ascites.
  • Early-age growth restriction (feed or light) can slow growth without compromising final body weight, potentially reducing ascites.

Conclusions:

  • Ascites syndrome in broiler chickens is strongly influenced by genetic predisposition and environmental factors, especially diet.
  • Managing broiler growth rate through early-life interventions is a viable strategy to decrease ascites incidence.
  • Optimizing environmental conditions, such as temperature and ventilation, also plays a role in ascites prevention.
