Management of delayed encephalopathy after CO poisoning: An evidence-based narrative review.

ABSTRACT: BACKGROUND:Approximately 10% to 30% patients develop delayed encephalopathy after acute CO poisoning (DEACMP). No specific treatment is available and poor prognosis is a characteristic of this disease. We aimed to evaluate the efficacy and safety of all therapies that have been tried in randomized controlled trial (RCT) for DEACMP. METHODS:We conducted a systematic search of the Cochrane, Embase, PubMed, and Web of Science databases. RESULTS:Overall, 4 RCTs were identified in our study. Both hyperbaric oxygen (HBO) and mesenchymal stem cell (MSC) transplantation were effective in DEACMP, and MSC seemed to be superior to HBO. The addition of dexamethasone, N-butylphthalide, or XingZhi-YiNao granules into HBO, or butylphthalide into MSC could achieve better neurological recovery in DEACMP patients but did not significantly increase the incidence of adverse events. CONCLUSION:Several therapies have shown positive results in treating DEACMP and need to be proven by further studies.

Project description:ObjectiveBased on network meta-analysis (NMA) and network pharmacology approaches, we explored the clinical efficacy of different regimens, and clarified the pharmacological mechanisms of N-butylphthalide (NBP) in the treatment of delayed encephalopathy after acute carbon monoxide poisoning (DEACMP).MethodsFirstly, NMA was conducted to obtain the ranking of the efficacy of different regimens for the treatment of DEACMP. Secondly, the drug with a relatively high efficacy ranking was selected and its mechanism of treatment for DEACMP was identified through a network pharmacology analysis. By the use of protein interaction and enrichment analysis, the pharmacological mechanism was predicted, and molecular docking was subsequently carried out to verify the reliability of the results.ResultsA total of 17 eligible randomized controlled trials (RCTs) involving 1293 patients and 16 interventions were eventually included in our analysis from NMA. Mesenchymal stem cells (MSCs) + NBP significantly increased mini-mental state examination (MMSE) and Barthel index (BI) scores; NBP + dexamethasone (DXM) was the most effective treatment in improving the activity of daily living (ADL) scores; NBP significantly decreased national institutes of health stroke scale (NIHSS) scores; Xingzhi-Yinao granules (XZYN) had more advantages in improving Montreal cognitive assessment (MoCA) scores, translational direct current stimulation (tDCS) had a significant effect in improving P300 latency and P300 amplitude and Kinnado + Citicoline had the most obvious effect in improving malondialdehyde (MDA). Meanwhile, by network pharmacology analysis, 33 interaction genes between NBP and DEACMP were obtained, and 4 of them were identified as possible key targets in the process of MCODE analysis. 516 Gene ontology (GO) entries and 116 Kyoto Encyclopedia of Gene and Genome (KEGG) entries were achieved by enrichment analysis. Molecular docking showed that NBP had good docking activity with the key targets.ConclusionThe NMA screened for regimens with better efficacy for each outcome indicator in order to provide a reference for clinical treatment. NBP can stably bind ALB, ESR1, EGFR, HSP90AA1, and other targets, and may play a role in neuroprotection for patients with DEACMP by modulating Lipid and atherosclerosis, IL-17 signaling pathway, MAPK signaling pathway, FoxO signaling pathway, PI3K/AKT signaling pathway.

Project description:Background and objectiveComplications associated with implant-based reconstruction have a spectrum of severity with sequelae ranging from mild aesthetic deformities to additional surgery, reconstructive failure and systemic illness. The purpose of this narrative review of the literature is to provide updated evidence-based information on the management of complications in implant-based reconstruction.MethodsA systematic search of PubMed, OVID MEDLINE and the Cochrane Library databases was performed to identify common complications associated with implant-based breast reconstruction, incidences of occurrence as well as preventative and management strategies.Key content and findingsPertinent short and long-term complications of implant-based breast reconstruction include hematoma, implant infection, seroma, skin envelope necrosis, capsular contracture, rupture, malposition, animation and contour deformities, implant-associated anaplastic large cell lymphoma, and breast implant illness. Important preventative measures for short term complications include meticulous sterile technique and antibiotic irrigation, adequate drainage and critical evaluation of mastectomy flaps. Management of short-term complications requires early recognition and aggressive treatment to prevent reconstructive failure as well as long-term complications such as capsular contracture. Important technological advances include dual-port expanders for seroma drainage, indocyanine green angiography for mastectomy flap perfusion evaluation, cohesive form-stable implants for treatment of rippling, and various biologic and synthetic mesh products for pocket control and correction.ConclusionsImportant principles in management of short-term complications in implant-based reconstruction include aggressive and early intervention to maximize the chance of reconstructive salvage. Contemporary technological advances have played an important role in both prevention and treatment of complications. Over-arching principles in management of implant-based reconstruction complications focus on preventative techniques and preoperative patient counseling on potential risks, their likelihood, and necessary treatments to allow for informed and shared decision-making.
