Randomized Controlled Trial Multicenter Study Pragmatic Clinical Trial
The Effect of Xinmailong Infusion on Sepsis-Induced Myocardial Dysfunction: A Pragmatic Randomized Controlled Trial.
Sepsis-induced myocardial dysfunction (SIMD) contributes significantly to cardiovascular dysfunction during septic shock. We aimed to evaluate the potential role of Xinmailong injection (XMLI), a polypeptide medicine extracted from Periplaneta americana, in reversing the progression of myocardial damage to SIMD in sepsis patients. This was a multicenter, randomized, double-blind, parallel-group trial. ⋯ In septic patients, XMLI decreased the occurrence rate of diastolic SIMD more effectively than the placebo. The improvement in serum BNP concentration was also greater in the XMLI group. XMLI may, therefore, effectively and safely improve cardiac function in patients with sepsis.

Macrophage, as an integral component of the immune system and the first responder to local damage, is on the front line of defense against infection. Over the past century, the prevailing view of macrophage origin states that all macrophage populations resided in tissues are terminally differentiated and replenished by monocytes from bone-marrow progenitors. Nonetheless, this theory has been reformed by ground-breaking discoveries from the past decades. ⋯ Moreover, multiple lines of evidence have indicated that tissue-resident macrophages play critical roles in maintaining tissue homeostasis and facilitating tissue repair through controlling infection and resolving inflammation. In this review, we summarize the properties of resident macrophages in the lung, spleen, and heart, and further highlight the impact of TRM populations on inflammation control and tissue repair. We also discuss the potential role of local proliferation in maintaining a physiologically stable TRM pool in response to acute inflammation.

Review Meta Analysis
Short-Term Efficacy and Safety of Different Mechanical Hemodynamic Support Devices for Cardiogenic Shock or High-Risk Pci: a Network Meta-Analysis of Thirty-Seven Trials.
With more advanced mechanical hemodynamic support for patients with cardiogenic shock (CS) or high-risk percutaneous coronary intervention (HS-PCI), the morality rate is now significantly lower than before. While previous studies showed that intra-aortic balloon pumping (IABP) did not reduce the risk of mortality in patients with CS compared to conservative treatment, the efficacy in other mechanical circulatory support (MCS) trials was inconsistent. ⋯ Following this analysis, ECMO+IABP might be a more suitable intervention measure in improving short-term mortality for patients with CS and who underwent HS-PCI. However, the result was limited by the lack of sufficient direct comparisons and evidence from randomized controlled trials. Moreover, bleeding and other device-related complications should be considered in clinical applications.

Severe heat stroke is a clinical syndrome caused by host stress dysfunction due to heat stress and subsequent life-threatening organ dysfunction. We aimed to explore the early risk factors affecting the 90-day prognosis of severe heat stroke patients. ⋯ The longer the cooling duration, the faster the heart rate at admission, and the higher the SOFA score, the lower the 90-day survival rate was. These three indicators can be used in combination to predict 90-day mortality and poor prognosis in patients with severe heat stroke.

Acute myocardial infarction (AMI) remains a major cause of mortality and morbidity, and cardiogenic shock (CS) a major cause of hospital mortality after AMI. Especially for ST elevation myocardial infarction (STEMI) patients, fast intervention is essential.Few proteins have proven clinically applicable for AMI. Most proposed biomarkers are based on a priori hypothesis-driven studies of single proteins, not enabling identification of novel candidates. For clinical use, the ability to predict AMI is important; however, studies of proteins in prediction models are surprisingly scarce.Consequently, we applied proteome data for identifying proteins associated with definitive STEMI, CS, and all-cause mortality after admission, and examined the ability of the proteins to predict these outcomes. ⋯ The association analyses propose individual proteins as putative protein biomarkers for definitive STEMI and survival after suspected STEMI, while the prediction models put forward sets of proteins with putative predicting ability of CS and survival. These proteins may be verified as biomarkers of potential clinical relevance.
