Identifying the effect of distinct plaque characteristics on clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI) is critical for clinical therapy. Our goal was to ascertain the correlation between clinical outcome, long-term prognosis, and morphological plaque characteristics in STEMI.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;The data used in this prospective cohort research came from a prior multicenter prospective cohort study (ChiCTR1800019923). One hundred and thirteen consecutive STEMI patients were involved in our cohort study. Patients with STEMI who received primary percutaneous coronary intervention (pPCI) within 24 hours of symptom onset were included in the study and divided into two groups according to plaque characteristics derived from intravascular ultrasound (IVUS): a PR group and a non-PR group. The primary outcome was the incidence of no reflow or slow flow, the secondary outcome was major adverse cardiac events (MACEs) at 1-year follow-up.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;This study enrolled 113 consecutive patients with STEMI [mean age 56 (range, 49-65.5) years; males 90.27%]. Of the 113 patients, PR was found in 93 (82.3%), while non-PR was found in 20 (17.7%). The PR group had a higher rates of plaque eccentricity index (64.28%±22.69% &lt;i&gt;vs&lt;/i&gt;. 60.08%±15.54%; P=0.045), higher rates of lipid pool-like images (62.37% &lt;i&gt;vs&lt;/i&gt;. 30.00%; P=0.008), and higher rates of tissue prolapse (22.95% &lt;i&gt;vs&lt;/i&gt;. 13.33%; P=0.01). Compared with that in the non-PR group, the incidence of no reflow or slow flow was higher in the PR group after pPCI (26.88% &lt;i&gt;vs&lt;/i&gt;. 5.00%; P=0.04). Multivariable logistic regression showed that PR [odds ratio (OR) =8.188; 95% confidence interval (CI): 1.020-65.734; P=0.048] was an independent predictor of no reflow or slow flow. Survival analysis revealed no significant differences in MACE incidence between the two groups at 1-year follow-up (7.61% &lt;i&gt;vs&lt;/i&gt;. 10.00%; P=0.66). Furthermore, 29 patients with PR were treated without stenting, most of them were free of MACEs (27/29).

This study is aimed to research the molecular mechanisms of sepsis-induced skeletal muscle atrophy and to develop new therapeutic strategies.</p><p><strong>Methods: </strong>In this study, we first constructed a mouse model of sepsis after cecal ligation and puncture (CLP). At 12, 24, 48, and 72 hours after modeling, we then analyzed the differentially expressed genes (DEGs) in the tibialis anterior muscle using transcriptome sequencing technology.</p><p><strong>Results: </strong>The results showed that tibialis anterior muscle atrophy exacerbated with time after CLP and was accompanied by the altered expression of a large number of genes. The expression profiling analysis showed that there were three transcriptional phases within 72 hours of surgery: transcriptional phase I (0-12 hours), transcriptional phase II (24 hours), and transcriptional phase III (48-72 hours), of which 24 hours may be the critical time point for muscle atrophy. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses showed that the upregulated genes were mainly involved in inflammatory immunity, proteolysis, apoptosis, and autophagy, while the downregulated genes were mainly involved in cell proliferation and protein synthesis. These three transcriptional phases were defined as the inflammatory-immune phase, inflammatory-atrophy phase, and atrophy phase, respectively.</p><p><strong>Conclusions: </strong>These findings not only enrich understandings of the molecular mechanism of sepsis-induced skeletal muscle atrophy, but also provide a scientific basis for its targeted therapy.</p>","PeriodicalId":17542,"journal":{"name":"Journal of thoracic disease","volume":"16 11","pages":"7751-7770"},"PeriodicalIF":2.1,"publicationDate":"2024-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11635243/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142829188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, there has been a rise in the number of patients with diabetes undergoing cardiac surgery. Despite the existence of national and international guidelines to improve surgical outcomes in patients with diabetes, perioperative diabetes management optimisation remains inadequate resulting in these patients experiencing increased rates of surgical morbidity and mortality. This review aims to evaluate outcomes following cardiac surgery in patients with diabetes and assess strategies to enhance preoperative and perioperative optimization and postoperative outcomes.</p><p><strong>Methods: </strong>A comprehensive literature search was performed for articles concerning perioperative management of diabetes in patients undergoing cardiac surgery as well as postoperative complications related to diabetes in addition to interventions utilised to optimize outcomes.</p><p><strong>Key content and findings: </strong>Principle findings were extracted and synthesized. Patients with diabetes undergoing cardiac surgery exhibit increased perioperative complications, higher in-hospital mortality rates and inferior long-term survival. A key facilitator is specifically poor glycemic control, with glycated haemoglobin (HbA1c) serving as a predictive marker. However, measuring preoperative HbA1c is not routine, and there is no established threshold for deferring elective surgery. Preoperatively, emphasis should be placed on lowering the patient's HbA1c through optimized medical management and continuous glucose monitoring. Intraoperatively, continuous insulin infusion therapy is recommended alongside postoperative continuation for critically ill patients. Prompt resumption of the patient's routine medications post-surgery is also necessary.</p><p><strong>Conclusions: </strong>Optimal glycemic control, both pre-, intra- and perioperatively, correlates with improved outcomes that are comparable to those without diabetes. Targeted efforts are warranted for patients with diabetes undergoing cardiac surgery to ensure long-term benefits for the patients and healthcare systems.</p>","PeriodicalId":17542,"journal":{"name":"Journal of thoracic disease","volume":"16 11","pages":"8088-8102"},"PeriodicalIF":2.1,"publicationDate":"2024-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11635245/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142829136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
