Burn patients' immune response.
Source publication
Patients with serious thermal burn injuries require immediate and specialized care in order to minimize morbidity and mortality. Optimal fluid resuscitation, nutritional support, pulmonary care, burn wound care, and infection control practices represent key aspects of patient care in burn centers. When severely burned, the patient usually presents...

... of severe burn patients could be summarized in two phases. The first one is a major proinflammatory response and may cause remote organ dysfunction. The second one is a counter anti-inflammatory response syndrome that may make patients and their exhausted and dysregulated immune system vulnerable to a potential second hit such as sepsis (shown in Fig. ...

... On wounding, elevated levels of IL-6 were detected within 24 h of bacterial infection during the initial inflammatory phase, which gradually diminished by the eighth day [65]. IL-6 was the only pro-inflammatory cytokine, the levels of which were persistently elevated post-burn injury; IL-6 levels in the serum peaked during the first few hours after injury and correlated directly with the area of the burn injury, the magnitude of the trauma, the duration of surgery, and the risk of postoperative complications [66]. IL-6 activity in human wound fluids was observed to peak within eight hours of surgery and return to baseline by the third day, a temporal pattern that may suppress the proliferation of fibroblasts in later stages [67]. ...
Wound healing is a complex and meticulously orchestrated process involving multiple phases and cellular interactions. This narrative review explores the intricate mechanisms behind wound healing, emphasizing the significance of cellular processes and molecular factors. The phases of wound healing are discussed, focusing on the roles of immune cells, growth factors, and extracellular matrix components. Cellular shape alterations driven by cytoskeletal modulation and the influence of the ‘Formin’ protein family are highlighted for their impact on wound healing processes. This review delves into the use of absorbable meshes in wound repair, discussing their categories and applications in different surgical scenarios. Interleukins (IL-2 and IL-6), CD31, CD34, platelet rich plasma (PRP), and adipose tissue-derived mesenchymal stem cells (ADSCs) are discussed in their respective roles in wound healing. The interactions between these factors and their potential synergies with absorbable meshes are explored, shedding light on how these combinations might enhance the healing process. Recent advances and challenges in the field are also presented, including insights into mesh integration, biocompatibility, infection prevention, and postoperative complications. This review underscores the importance of patient-specific factors and surgical techniques in optimizing mesh placement and healing outcomes. As wound healing remains a dynamic field, this narrative review provides a comprehensive overview of the current understanding and potential avenues for future research and clinical applications.
Burn injury is associated with a high risk of acute kidney injury (AKI) with a prevalence of AKI among patients with burns of 9-50%. Despite an improvement in burn injury survival in the past decade, AKI in patients with burns is associated with an extremely poor short-term and long-term prognosis, with a mortality of >80% among those with severe AKI. Factors that contribute to the development of AKI in patients with burns include haemodynamic alterations, burn-induced systemic inflammation and apoptosis, haemolysis, rhabdomyolysis, smoke inhalation injury, drug nephrotoxicity and sepsis. Early and late AKI after burn injury differ in their aetiologies and outcomes. Sepsis is the main driver of late AKI in patients with burns and late AKI has been associated with higher mortality than early AKI. Prevention of early AKI involves correction of hypovolaemia and avoidance of nephrotoxic drugs (for example, hydroxocobalamin), whereas prevention of late AKI involves prevention and early recognition of sepsis as well as avoidance of nephrotoxins. Treatment of AKI in patients with burns remains supportive, including prevention of fluid overload, treatment of electrolyte disturbance and use of kidney replacement therapy when indicated.
The advantages and disadvantages of using corticosteroids in children undergoing cardiac surgery is still contentious. To examine how perioperative corticosteroids affect postoperative mortality and clinical outcomes in pediatric cardiac surgery with cardiopulmonary bypass (CPB). We used MEDLINE, EMBASE, and the Cochrane Database to conduct a comprehensive search up through January 2023. Children aged 0-18 undergoing cardiac surgery were included in the meta-analysis of randomized controlled studies comparing perioperative corticosteroids with other therapeutic therapies, placebo, or no treatment. All-cause hospital mortality was the primary endpoint of the study. Hospitalization duration was a secondary result. The Cochrane Risk of Bias Assessment Tool was used to evaluate the research quality. Ten trials and 7798 pediatric participants were included in our analysis. Children taking corticosteroids had no significant difference in all-cause in-hospital mortality using a random-effect model with relative risk (RR) = 0.38, 95% confidence interval (CI) = 0.16-0.91, I2 = 79%, p = .03 for methylprednisolone and RR = 0.29, 95% CI = 0.09-0.97, I2 = 80%, p = .04. For the secondary outcome, there was a significant difference between the corticosteroid and placebo groups, with pooled standard mean difference (SMD) = -0.86, 95% CI = -1.57 to -0.15, I2 = 85%, p = .02 for methylprednisolone and SMD = -0.97, 95% CI -1.90 to -0.04, I2 = 83%, p = .04 for dexamethasone. Perioperative corticosteroids may not improve mortality, but they reduce hospital stay compared to placebo. Further evidence from randomized controlled studies with larger samples is required for approaching at a valid conclusion.
