Nutritional status and nutritional intervention of older inpatients in China.

Background: Malnutrition is a critical issue among older inpatients, yet limited large-scale research related to this issue has been conducted in China. This study aimed to examine the nutritional status and support of older inpatients in China, assess the associations between disease categories and malnutrition on admission, and explore effective nutritional intervention.

Methods: A total of 24,139 older participants from the China Nutrition Fundamental Data 2020 Project were included.

Predictive Value of Perioperative Cardiac Troponin I in Patients Undergone Liver Transplantation: A Retrospective Cohort Study.

Objective: To examine the change rule and clinical significance of cardiac troponin I (cTnI) in the perioperative period of liver transplantation in adults, as well as its association with 28-day mortality.

Methods: This was a retrospective cohort study: patients who underwent elective orthotopic liver transplantation (OLT) in Beijing Chao-Yang Hospital between June 2015 and June 2020 were selected, and plasma cTnI values were collected through the electronic medical record system within 7 days after surgery. Furthermore, the baseline clinical data of these patients were collected, and the change curve of cTnI values following liver transplantation was plotted.

An inquiry into the treatment of sepsis using plasma exchange therapy: A systematic review and meta-analysis.

Sepsis is a potentially lethal condition that occurs when the body's response to infection damages tissue and organs. The production of inflammatory mediators typically assists in defending the body against infection; however, an overreaction to inflammation can cause coagulation problems, vascular endothelial damage, and organ hypoperfusion. Blood purification methods, such as plasmapheresis, can effectively remove inflammatory mediators from plasma.

Cell cycle arrest biomarkers for predicting renal recovery from acute kidney injury: a prospective validation study.

Background: Acute kidney injury (AKI) is a common disease in the intensive care unit (ICU). AKI patients with nonrecovery of renal function have a markedly increased risk of death compared with patients with recovery. The current study aimed to explore and validate the utility of urinary cell cycle arrest biomarkers for predicting nonrecovery in patients who developed AKI after ICU admission.

Development of a Multivariable Prediction Model for Citrate Accumulation in Liver Transplant Patients Undergoing Continuous Renal Replacement Therapy with Regional Citrate Anticoagulation.

Introduction: Patients with impaired citrate metabolism may experience citrate accumulation (CA), which causes life-threatening metabolic acidosis and hypocalcemia. CA poses a challenge for clinicians when deciding on the use of regional citrate anticoagulation (RCA) for patients with liver dysfunction. This study aimed to develop a prediction model integrating multiple clinical variables to assess the risk of CA in liver transplant patients.

Prognostic value of dynamic plasma endostatin for the prediction of mortality in acute kidney injury: A prospective cohort study.

Objective: The aim of the current study was to evaluate the value of plasma endostatin for predicting 30-day mortality of patients with acute kidney injury (AKI).

Methods: Patients who underwent non-cardiac major surgery and developed AKI in the first 48 hours after admission to the intensive care unit were consecutively included. Concentrations of plasma neutrophil gelatinase-associated lipocalin (NGAL), cystatin C (Cys C), and endostatin were measured at three time points: 0, 24, and 48 hours after the AKI diagnosis.

Derivation and validation of plasma endostatin for predicting renal recovery from acute kidney injury: a prospective validation study.

Background: Acute kidney injury (AKI) is associated with high morbidity and mortality in surgical patients. Nonrecovery from AKI may increase mortality and early risk stratification seems key to improving clinical outcomes. The aim of the current study was to explore and validate the value of endostatin for predicting failure to recover from AKI.

Pep-3D-Search: a method for B-cell epitope prediction based on mimotope analysis.

Background: The prediction of conformational B-cell epitopes is one of the most important goals in immunoinformatics. The solution to this problem, even if approximate, would help in designing experiments to precisely map the residues of interaction between an antigen and an antibody. Consequently, this area of research has received considerable attention from immunologists, structural biologists and computational biologists.

[The formation of BPDE-DNA adduct in rat and its determination by high performance liquid chromatography].

Objective: To study the benzo (a) pyrene (BaP) induced DNA adduct in rat and establish a method to measure the DNA adduct in blood by high performance liquid chromatography (HPLC).

Methods: The SD rats were treated with 100 mg/kg of BaP-DMSO (cosolvent: 1% sodium carboxymethyl cellulose) once by i.p.
