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.

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.

We previously showed that the addition of valproic acid (VPA), a histone deacetylase inhibitor, to fresh frozen plasma (FFP) resuscitation attenuates brain lesion size and swelling following traumatic brain injury (TBI) and hemorrhagic shock (HS). The goal of this study was to use computational biology tools to investigate the effects of FFP+VPA on the brain transcriptome following TBI+HS. ⋯ Overall, these results suggest that VPA treatment creates an environment that favors production of new neurons, removal of damaged cells, and attenuation of inflammation, which could explain its previously observed neuroprotective effects.

The optimal effective temperature of targeted temperature management (TTM) used to prevent cerebral injury following cardiopulmonary resuscitation (CPR) is undetermined. In this study, we compared the mortality, neurologic deficits, and cerebral protein levels of two target temperatures. ⋯ Lower target temperature showed greater protective effects against cerebral injuries after CPR, and the improved neurological outcomes after TTM may be associated with decreased expression of pro-inflammatory cytokines and increased expression of blood-brain barrier and neurogenesis regulatory factors in this porcine model of CA following resuscitation.
