[Current role of albumin in critical care].

Published: November 2014

The use of colloids in fluid therapy has been, and still continues to be a controversial topic, particularly when referring to the critical patient. The choice of the fluid that needs to be administered depends on several factors, many of which are theoretical, and continue being an object of debate. The interest in the clinical use of the albumin has emerged again, immediately after recent publications in the search of the most suitable colloid. It is the most abundant protein in the plasma, being responsible for 80% of the oncotic pressure. It regulates the balance between the intra- and extra-vascular volumes. Recent multicenter studies question the supposed lack of safety that was previously assigned to it. Furthermore, in vitro studies demonstrate other important actions besides oncotic, for example neutralization of free radicals, and exogenous (drugs) and endogenous substances (bile pigments, cholesterol). Being aware of these secondary properties of albumin, and evaluating the pathophysiology of the critical patient (in particular, sepsis), to maintain plasma albumin levels within the normal range, could be of great importance. Based on the most recent publications, the aim of this review is to briefly analyze the pathophysiology of albumin, as well as to discuss its possible indications in the critical patient.

Background: Previous studies regarding mind-body exercise among people with breast cancer mostly focused on one type of mind-body exercise and provided conflicting results.

Aims: This paper aims to systematically synthesize the evidence hierarchy and examine the credibility of previous meta-analyses of different types of mind-body exercises.

Methods: We searched PubMed, Embase, Cochrane Library, Web of Science, and Epitemonikos from database inception to February 2nd, 2024, for meta-analyses of randomized controlled trials.

Unveiling the Role of Protein Posttranslational Modifications in Glioma Prognosis.

CNS Neurosci Ther

March 2025

Department of Neurosurgery, Xiangya Hospital, Central South University, Changsha, Hunan, P.R. China.

Background: Gliomas represent the most aggressive malignancies of the central nervous system, with posttranslational modifications (PTMs) emerging as critical regulators of oncogenic processes through dynamic protein functional modulation. Despite their established role in tumor biology, the systematic characterization of PTM-mediated molecular mechanisms driving glioma progression remains unexplored. This study aims to uncover the molecular mechanisms of glioma, with a focus on the role of PTMs.

Aim: This study aimed to investigate the relationship between the Cancer Inflammation Prognostic Index (CIPI) and microsatellite instability (MSI), tumor budding, and prognosis in colorectal cancer cases.

Methods: Patients with stage 1-3 colorectal cancer who underwent curative surgical treatment between May 2020 and January 2022 were included. Serum CIPI was calculated, a cut-off point was established using Receiver Operating Characteristic (ROC) analysis and Patients were divided into two groups according to their CIPI scores: Group 1 (low CIPI) consisted of 94 patients, and Group 2 (high CIPI) consisted of 95 patients.
