Risk Prediction Model for Adult Intolerance to Enteral Nutrition Feeding - A Literature Review.
Enteral nutrition is an important clinical nutritional supplementation method, especially for adult patients who are unable to eat normally or require additional nutritional support. However, many patients experience intolerance to enteral nutrition, such as delayed gastric emptying, bloating, and diarrhea, which not only affect the patient's nutritional status but also increase the risk of medical complications. ⋯ These models typically combine clinical parameters, biomarkers, and patient individual characteristics, aiming to assist clinicians in better planning and adjusting nutritional treatment plans, thereby reducing the occurrence of intolerance events. This review summarizes the research progress on enteral nutrition intolerance in adult patients, with a focus on the latest developments in intolerance factors and risk prediction models, providing valuable guidance for clinical practice and helping improve patients' nutritional status and overall health.

A pancreatic fistula is defined as the leakage of pancreatic fluid into another organ or compartment because of pancreatic duct disruption or pseudocyst formation. It is most often seen in middle-aged men between 40 and 50, particularly in patients who have a history of chronic alcoholism and pancreatitis. The tract may fistulae into the pleura, creating a pancreaticopleural fistula, an exceedingly rare condition presenting as a recurrent pleural effusion and extremely high amylase levels, a key distinguishing factor in diagnosis. Here, we present such a case of a recurrent pancreaticopleural fistula and review the presentation, pathophysiology, diagnosis and treatment.

Alpha-gal syndrome develops in some individuals who have had tick bites which result in IgE responses to alpha-gal, a carbohydrate not found in humans. Patients with alpha-gal syndrome develop symptoms when they ingest mammalian meat, which contains this oligosaccharide. Often the response to this exposure is delayed and occurs 2 to 6 h post-ingestion. ⋯ Patients can also have adverse reactions to medications, such as set cetuximab, heparin, monoclonal antibodies, and pancreatic enzymes, and clinicians will likely have difficulty identifying these reactions. If patients have a good response to diet modification and have a significant reduction in their specific IgE level to alpha-gal, they potentially can resume eating meat in their diet. This should be done under the direction of a specialist.

Clinicians frequently evaluate patients who present with dyspnea. This term describes uncomfortable breathing during physical activity, and the intensity or degree of dyspnea can vary in an individual depending on circumstances and between individuals. ⋯ This hypothesis suggests that prior experiences with dyspnea during physical activity or a respiratory disorder provide the background that is used to interpret current symptoms. This review outlines problems associated with the use of the term "dyspnea" and briefly describes how the Bayesian brain hypothesis might help clinicians understand this symptom better.

The QT interval, an electrocardiographic temporal representation of the ventricular depolarization and repolarization, is an integral parameter that must be carefully evaluated to gather critical information regarding electrical instability that may cause malignant ventricular dysrhythmias or sudden cardiac death. The QT interval is affected by several inheritable and acquired factors, such as genetic mutations, electrolyte disturbances, and medication interactions. We strongly believe that prompt and accurate recognition of any QT interval abnormalities is critical in many clinical settings. This concise review article highlights the importance of accurate measurement of the QT interval, enhances understanding of the most prevalent factors yielding abnormalities within the QT interval and the prognostic value of the QT interval, as well as provides several key practical reminders for healthcare professionals to strengthen our clinical practice.
