MELD Score
The Model for End-Stage Liver Disease, or MELD, is a scoring system for assessing the severity of chronic liver disease. It was initially developed to predict mortality within three months of surgery in patients who had undergone a transjugular intrahepatic portosystemic shunt (TIPS) procedure, and was subsequently found to be useful in determining prognosis and prioritizing for receipt of a liver transplant. This score is now used by the United Network for Organ Sharing (UNOS) and Eurotransplant for prioritizing allocation of liver transplants instead of the older Child-Pugh score. Determination MELD uses the patient's values for serum bilirubin, serum creatinine, and the international normalized ratio for prothrombin time (INR) to predict survival. It is calculated according to the following formula: \mathrm \overset 3.78\times \ln \left(\text\right) + 11.2 \times \ln(\text) + 9.57\times \ln\left( \text\right) + 6.43 MELD scores are reported as whole numbers, so the result ...

Serum Creatinine
Creatinine (; ) is a breakdown product of creatine phosphate from muscle and protein metabolism. It is released at a constant rate by the body (depending on muscle mass). Biological relevance Serum creatinine (a blood measurement) is an important indicator of kidney function, because it is an easily measured byproduct of muscle metabolism that is excreted unchanged by the kidneys. Creatinine itself is produced via a biological system involving creatine, phosphocreatine (also known as creatine phosphate), and adenosine triphosphate (ATP, the body's immediate energy supply). Creatine is synthesized primarily in the liver by methylation of glycocyamine (guanidino acetate, synthesized in the kidney from the amino acids arginine and glycine) by S-adenosyl methionine. It is then transported in the blood to other organs, muscles, and the brain, where it is phosphorylated to phosphocreatine, a high-energy compound. Creatine conversion to phosphocreatine is catalysed by creatine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hepatology
Hepatology is the branch of medicine that incorporates the study of liver, gallbladder, biliary tree, and pancreas as well as management of their disorders. Although traditionally considered a sub-specialty of gastroenterology, rapid expansion has led in some countries to doctors specializing solely on this area, who are called hepatologists. Diseases and complications related to viral hepatitis and alcohol are the main reason for seeking specialist advice. More than two billion people have been infected with hepatitis B virus at some point in their life, and approximately 350 million have become persistent carriers. Up to 80% of liver cancers can be attributed to either hepatitis B or hepatitis C virus. In terms of Mortality rate, mortality, the former is second only to smoking among known agents causing cancer. With more widespread implementation of vaccination and strict Screening (medicine), screening before blood transfusion, lower infection rates are expected in the futur ...

Milan Criteria
In transplantation medicine, the Milan criteria are set of criteria applied in consideration of patients with cirrhosis and hepatocellular carcinoma (HCC) for liver transplantation with intent to cure their disease. Their significance derives from a landmark 1996 study in 48 patients by Mazzaferro ''et al'' which showed that selecting cases for transplantation according to specific strict criteria led to improved overall and disease-free survival at a four-year time point. These same criteria have since been adopted by the Organ Procurement and Transplantation Network (OPTN) in the evaluation of patients for potential transplantation.The threshold Milan criteria are as follows: * one lesion smaller than 5 cm; ''alternatively,'' up to three lesions, each smaller than 3 cm * no extrahepatic manifestations * no evidence of gross vascular invasion Under current OPTN/ONUS guidelines, patients with cirrhosis and HCC who meet these criteria may be considered for transplantation. ...

New England Journal Of Medicine
''The New England Journal of Medicine'' (''NEJM'') is a weekly medical journal published by the Massachusetts Medical Society. Founded in 1812, the journal is among the most prestigious peer-reviewed medical journals. Its 2023 impact factor was 96.2, ranking it 2nd out of 168 journals in the category "Medicine, General & Internal". History In September 1811, Boston physician John Collins Warren, along with James Jackson, submitted a formal prospectus to establish the ''New England Journal of Medicine and Surgery and Collateral Branches of Science'' as a medical and philosophical journal. Subsequently, the first issue of the ''New England Journal of Medicine and Surgery and the Collateral Branches of Medical Science'' was published in January 1812. The journal was published quarterly. In 1823, another publication, the ''Boston Medical Intelligencer'', appeared under the editorship of Jerome V. C. Smith. The editors of the ''New England Journal of Medicine and Surgery and the ...

MELD-Plus
MELD-Plus is a risk score to assess severity of chronic liver disease that was resulted from a collaboration between Massachusetts General Hospital and IBM. The score includes nine variables as effective predictors for 90-day mortality after a discharge from a cirrhosis-related admission. The variables include all Model for End-Stage Liver Disease (MELD)'s components, as well as sodium, albumin, total cholesterol, white blood cell count, age, and length of stay. Because total cholesterol and hospital length of stay are typically not uniform factors across different hospitals and may vary in different countries, an additional model that included only seven of the nine variables was evaluated. This yielded a performance close to the one of using all nine variables and resulted in the following associations with increased mortality: INR, creatinine, total bilirubin, sodium, WBC, albumin, and age. The development of MELD-Plus was based on using unbiased approach toward discovery of bi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kidney Dialysis
Kidney dialysis is the process of removing excess water, solutes, and toxins from the blood in people whose kidneys can no longer perform these functions naturally. Along with kidney transplantation, it is a type of renal replacement therapy. Dialysis may need to be initiated when there is a sudden rapid loss of kidney function, known as acute kidney injury (previously called acute renal failure), or when a gradual decline in kidney function, chronic kidney failure, reaches stage 5. Stage 5 chronic renal failure is reached when the glomerular filtration rate is less than 15% of the normal, creatinine clearance is less than 10 mL per minute, and uremia is present. Dialysis is used as a temporary measure in either acute kidney injury or in those awaiting kidney transplant and as a permanent measure in those for whom a transplant is not Indication (medicine), indicated or not possible.Pendse S, Singh A, Zawada E.
