Introduction: Fluid administration is the cornerstone in hypovolemic patient's reanimation. Clinical guidelines restrict colloid administration favouring crystalloids. Currently, we don't know exactly which is the daily clinical practice during the perioperative period. The objective of this study is to describe perioperative use of colloids analysing possible reasons aiming to use them.
Material And Methods: Prospective, cross-section, national, multicentre observational study. Fluid Day sub-study. We enrolled all patient's older than 18 years old who underwent surgery during the 24 h of the 2-days study (February, 2019, 18th and 20th). We registered demographic data, comorbidities, anaesthetic and surgical procedure data, fluids administered, perioperative bleeding and monitoring type used during the perioperative period.
Results: A total of 5928 cases were analysed and 542 patients (9.1%) received any type of colloids, being hydroxiethyl-starch the most frequently used (5.1%). Patients receiving colloids suffered more longing surgery (150 [90-255] vs. 75 [45-120] min), were urgently operated (13.7 vs. 7.5%) and were more frequent classified as high risk (22 vs. 4.8%). Their recovery was mostly in critical care units (45.1 vs.15.8%). Patients with bleeding less than 500 ml received colloids in a percentage of 5.9 versus 45.9% when this figure was overcome. Patients who received colloids were anaemic more frequently: 29.4 vs. 16.3%. Colloids administration had a higher risk for transfusion (OR 15.7). Advanced monitoring also increased the risk for receiving colloids (OR 9.43).
Conclusions: In our environment with routine clinical practice, colloids administration is limited and close linked to perioperative bleeding.

Introduction: Acute normovolaemic haemodilution (ANH) is a perioperative blood management technique involving the removal of whole blood and simultaneous infusion of colloids or crystalloids to achieve haemodilution while maintaining normovolaemia. However, its efficacy in reducing the requirement for perioperative allogeneic blood transfusion remains controversial due to inconsistent findings in the literature. An individualised red cell transfusion strategy, guided by the West China Liu's Score, has demonstrated effectiveness in reducing the need for allogeneic red cell transfusion.

Penetrating orocutaneous or oropharyngeal fistulas (POFs), severe complications following unsuccessful oral or oropharyngeal reconstruction, remain complex clinical challenges due to lack of supportive tissue, contamination with saliva and chewed food, and dynamic oral environment. Here, we present a Janus hydrogel adhesive (JHA) with asymmetric functions on opposite sides fabricated via a facile surface enzyme-initiated polymerization (SEIP) approach, which self-entraps surface water and blood within an in-situ formed hydrogel layer (RL) to effectively bridge biological tissues with a supporting hydrogel (SL), achieving superior wet-adhesion and seamless wound plugging. The tough SL hydrogel interlocked with RL dissipates energy to withstand external mechanical stimuli from continuous oral motions like chewing and swallowing, thus reducing stress-induced damage.

Impaired spinal GABAergic inhibitory neuronal system is one popular target for developing new drugs or procedures for treatment of neuropathic pain, but effective and transferable methods are still lacking. We designed an assembled, temperature sensitive and sustained releasing hydrogel to repair the impaired GABAergic neural system by reversing imbalance of glutamic acid (Glu) and γ-aminobutyric acid (GABA) and healing impaired Cl extrusion capacity of neurons. Hydrogel solution is a mixture of pluronic F-127, recombinant glutamate decarboxylase 67 (rGAD67) protein and CLP257, a K-Cl cotransporter isoform 2 (KCC2) enhancer.

Owing to many diseases and disorders being caused by dysfunctional or over/underexpressed enzymes, screening for inhibitors of pharmacologically relevant enzymes has emerged as a promising tool for drug discovery, clinical diagnostics, enzyme engineering, and other medical fields. However, despite the recent advances, most inhibitor screenings are still usually conducted in dilute media, at concentrations far from the media in which the enzymes are actually found, which may cause drugs to fail when translated to . Herein, we build a gel-like intracellular biological environment using a tyrosinase oxidative cross-linking hydrogel system that is closer to the real catalytic environment of enzymes.

Biomaterial-associated infections pose severe challenges in modern medicine. Previously, we reported that polyanionic DNA surface coatings repel bacterial adhesion and support osteoblast-like cell attachment in monoculture experiments, candidate for orthopaedic implant coatings. However, monocultures lack the influence of bacteria or bacterial toxins on osteoblast-like cell adhesion to biomaterial surfaces.
