| 1 | Challenges and innovations in treating chronic and acute wound infections:from basic science to clinical practice显示文摘Acute and chronic wound infection has become a major worldwide healthcare burden leading to significantly high morbidity and mortality.The underlying mechanism of infections has been widely investigated by scientist,while standard wound management is routinely been used in general practice.However,strategies for the diagnosis and treatment of wound infections remain a great challenge due to the occurrence of biofilm colonization,delayed healing and drug resistance.In the present review,we summarize the common microorganisms found in acute and chronic wound infections and discuss the challenges from the aspects of clinical diagnosis,non-surgical methods and surgical methods.Moreover,we highlight emerging innovations in the development of antimicrobial peptides,phages,controlled drug delivery,wound dressing materials and herbal medicine,and find that sensitive diagnostics,combined treatment and skin microbiome regulation could be future directions in the treatment of wound infection. | Xiaotong Ding Qinghan Tang Zeyu Xu Ye Xu Hao Zhang Dongfeng Zheng Shuqin Wang Qian Tan Joanneke Maitz Peter K.Maitz Shaoping Yin Yiwei Wang Jun Chen | 2022 | Burns & Trauma2022，10，1： | 3 |
| 2 | Low-protein diet accelerates wound healing in mice post-acute injury显示文摘Background:Wound healing processes are influenced by macronutrient intake(protein,carbohydrate and fat).The most favourable diet for cutaneous wound healing is not known,although highprotein diets are currently favoured clinically.This experimental study investigates the optimal macronutrient balance for cutaneous wound healing using a mouse model and the Geometric Framework,a nutrient modelling method,capable of analyzing the individual and interactive effects of a wide spectrum of macronutrient intake.Methods:Two adjacent and identical full-thickness skin excisions(1 cm^(2))were surgically created on the dorsal area of male C57BL/6 mice.Mice were then allocated to one of 12 high-energy diets that varied in protein,carbohydrate and fat content.In select diets,wound healing processes,cytokine expression,energy expenditure,body composition,muscle and fat reserves were assessed.Results:Using the Geometric Framework,we show that a low-protein intake,coupled with a balanced intake of carbohydrate and fat is optimal for wound healing.Mice fed a low-protein diet progressed quickly through wound healing stages with favourable wound inflammatory cytokine expression and significantly accelerated collagen production.These local processes were associated with an increased early systemic inflammatory response and a higher overall energy expenditure,related to metabolic changes occurring in key macronutrient reserves in lean body mass and fat depots.Conclusions:The results suggest that a low-protein diet may have a greater potential to accelerate wound healing than the current clinically used high-protein diets. | Jonathan J.Hew Roxanne J.Parungao Craig P.Mooney Julian K.Smyth Sarah Kim Kevin H.-Y.Tsai Huaikai Shi Cassandra Chong Renee C.F.Chan Beba Attia Caroline Nicholls Zhe Li Samantha M.Solon-Biet David G.Le Couteur Stephen J.Simpson Marc G.Jeschke Peter K.Maitz Yiwei Wang | 2021 | Burns & Trauma2021，9，1： | 0 |
| 3 | The contradictory role of androgens in cutaneous and major burn wound healing显示文摘Wound healing is a complex process involving four overlapping phases:haemostasis,inflammation,cell recruitment and matrix remodeling.In mouse models,surgical,pharmacological and genetic approaches targeting androgen actions in skin have shown that androgens increase interleukin-6 and tumor necrosis factor-αproduction and reduce wound re-epithelization and matrix deposition,retarding cutaneous wound healing.Similarly,clinical studies have shown that cutaneous wound healing is slower in men compared to women.However,in major burn injury,which triggers not only local wound-healing processes but also systemic hypermetabolism,the role of androgens is poorly understood.Recent studies have claimed that a synthetic androgen,oxandrolone,increases protein synthesis,improves lean body mass and shortens length of hospital stay.However,the possible mechanisms by which oxandrolone regulates major burn injury have not been reported.In this review,we summarize the current findings on the roles of androgens in cutaneous and major burn wound healing,as well as androgens as a potential therapeutic treatment option for patients with major burn injuries. | Huaikai Shi Kenny Cheer Ulla Simanainen Brian Lesmana Duncan Ma Jonathan J.Hew Roxanne J.Parungao Zhe Li Mark S.Cooper David J.Handelsman Peter K.Maitz Yiwei Wang | 2021 | Burns & Trauma2021，9，1： | 0 |
