Selenomethionine in gelatin methacryloyl hydrogels: Modulating ferroptosis to attenuate skin aging.

During skin aging, the degeneration of epidermal stem cells (EpiSCs) leads to diminished wound healing capabilities and epidermal disintegration. This study tackles this issue through a comprehensive analysis combining transcriptomics and untargeted metabolomics, revealing age-dependent alterations in the gene family and arachidonic acid (AA) metabolic networks, resulting in enhanced ferroptosis. Selenomethionine (Se-Met) could enhance GPX4 expression, thereby assisting EpiSCs in countering AA-induced mitochondrial damage and ferroptosis.

Development and validation of a nomogram for pneumonia risk in burn patients with inhalation injury: a multicenter retrospective cohort study.

Background: Burn patients with inhalation injury are at higher risk of developing pneumonia, and yet there is no reliable tool for the assessment of the risk for such patients at admission. This study aims to establish a predictive model for pneumonia risk for burn patients with inhalation injury based on clinical findings and laboratory tests.

Method: This retrospective study enrolled 546 burn patients with inhalation injury.

A nanoenzyme-modified hydrogel targets macrophage reprogramming-angiogenesis crosstalk to boost diabetic wound repair.

A novel skin grafting modality: prefabricated large sheet of postage-stamp autografts and allografts to repair extensive burn wounds; a prospective matched-control study.

Background: The excessively long operative time has been the greatest barrier to the success of transplanting postage-stamp auto- and allografts directly and piece-by-piece onto extensive burn wounds. To solve this challenge, the authors present a novel grafting modality, that is, the prefabricated-large-sheet grafting that moves the labor-intensive and time-consuming process of grafts-positioning before grafting and thereby markedly shortens the operative time.

Methods: Twenty-one operations using the novel modality were performed on 11 patients with extensive deep burns.

Upregulation of IDO gene expression reduces the immunogenicity of epidermal cells and strengthens the immune protection of epidermal cells during transplantation treatment of wounds.

Background: Epidermal cell transplantation is a feasible treatment option for large wounds; however, sources of autologous epidermal cells are often limited. Allogeneic epidermal cells can be cultured conveniently; however, related immune rejection needs to be addressed. Herein, we hypothesized that the immunogenicity of epidermal cells with high indoleamine 2,3-dioxygenase (IDO) expression may be reduced by gene transfection.

A study on the preoperative risk factors for primary healing failure in the reconstruction of deep sternal wound infection with platelet-rich plasma and negative pressure trauma therapy.

Deep sternal wound infection (DSWI) is a relatively complex wound in wound reconstruction surgery. Because plastic surgeons deal with DSWI patients late. The primary healing (healing by first intention) after reconstruction of DSWI is restricted by many preoperative risk factors.

Review on risk factors, classification, and treatment of sternal wound infection.

Sternal wound infection (SWI) is the most common complication of the median sternal incision. The treatment time is long, and the reconstruction is difficult, which causes challenges for surgeons. Plastic surgeons were often involved too late in such clinical scenarios when previous empirical treatments failed and the wound damage was relatively serious.

A Potential Resuscitation Route on Battlefield: Immediate Intraperitoneal Fluid Administration Post-burn Shows Satisfactory Fluid Absorption and Anti-shock Effects.

Introduction: Timely fluid resuscitation remains the key to the early treatment of severe burns. Intraperitoneal (IP) fluid administration is a simple, rapid resuscitation strategy via a puncture in the abdominal wall. This study aimed to evaluate the fluid absorption and anti-shock effects of IP delivery in the early stage after severe burns.

An innovated elastic compression hemostasis technique for extremity excision in patients with extensive burns: A prospective clinical randomized controlled trial.

Objective: To introduce an innovative elastic compression hemostasis technique for extremity excision in extensively burnt patients and investigate its effectiveness.

Methods: Ten patients were included and divided into 2 groups: the control group (4 patients, 12 extremities) receiving the conventional hemostasis technique and the experimental group (6 patients, 14 extremities) receiving the innovative technique. General data of the patients were collected, excision size measured, hemostasis time recorded, average blood loss per 1% total body surface area of the excised wound calculated, incidence of subcutaneous hematoma and take rate determined.

Functional and aesthetic outcomes of abdominal full-thickness skin grafts in paediatric postburn digital and palmar flexion contractures.
