Summary
Feeding horses more concentrate and allowing pasture grazing were associated with a higher risk of developing duodenitis-proximal jejunitis (DPJ). These feeding practices may offer etiological clues for DPJ in horses.
Area of Science:
- Equine medicine
- Gastroenterology
- Animal science
Background:
- Duodenitis-proximal jejunitis (DPJ) in horses has been linked to concentrate feeding, but this association requires controlled study.
- A systematic evaluation of feeding practices and DPJ risk is needed.
Purpose of the Study:
- To investigate the association between feeding practices and the likelihood of developing DPJ in horses.
- To compare feeding habits of DPJ cases with control groups.
Main Methods:
- A case-control study design was employed.
- Feeding practices of DPJ cases (1997-2003) were compared to colic and lameness controls.
- Polytomous logistic regression was used after data imputation.
Main Results:
- Horses with DPJ consumed significantly more concentrate daily compared to controls.
- DPJ cases were more likely to have grazed pasture and be female than lameness controls.
- Results remained consistent after adjusting for horse bodyweight.
Conclusions:
- Feeding and grazing practices differ between horses with DPJ and those with other conditions.
- The identified associations, while not diagnostic, may provide etiological insights into DPJ.

01:15Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding
Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

01:30Acute 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...
01:21Acute 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...

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...

Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.
