We examined the cardioprotective profile of the new A 3 adenosine receptor (AR) agonist 903 [N 6 -(2,5-dichlorobenzyl)-3Ј-aminoadenosine-5Ј-N-methylcarboxamide] in an in vivo mouse model of infarction and an isolated heart model of global ischemia/reperfusion injury. In radioligand binding and cAMP accumulation assays using human embryonic kidney 293 cells expressing recombinant mouse ARs, CP-532,903 was found to bind with high affinity to mouse A 3 ARs (K i ϭ 9.0 Ϯ 2.5 nM) and with high selectivity versus mouse A 1 AR (100-fold) and A 2A ARs (1000-fold). In in vivo ischemia/reperfusion experiments, pretreating mice with 30 or 100 g/kg CP-532,903 reduced infarct size from 59.2 Ϯ 2.1% of the risk region in vehicle-treated mice to 42.5 Ϯ 2.3 and 39.0 Ϯ 2.9%, respectively. Likewise, treating isolated mouse hearts with CP-532,903 (10, 30, or 100 nM) concentration dependently improved recovery of contractile function after 20 min of global ischemia and 45 min of reperfusion, including developed pressure and maximal rate of contraction/relaxation. In both models of ischemia/reperfusion injury, CP-532,903 provided no benefit in studies using mice with genetic disruption of the A 3 AR gene, A 3 knockout (KO) mice. In isolated heart studies, protection provided by CP-532,903 and ischemic preconditioning induced by three brief ischemia/ reperfusion cycles were lost in Kir6.2 KO mice lacking expression of the pore-forming subunit of the sarcolemmal ATPsensitive potassium (K ATP ) channel. Whole-cell patch-clamp recordings provided evidence that the A 3 AR is functionally coupled to the sarcolemmal K ATP channel in murine cardiomyocytes. We conclude that CP-532,903 is a highly selective agonist of the mouse A 3 AR that protects against ischemia/reperfusion injury by activating sarcolemmal K ATP channels.A 3 adenosine receptor (AR) agonists have been shown to effectively limit infarct size and reduce contractile dysfunction in several different animal models of ischemia/reperfusion injury (Auchampach et al., 1997b(Auchampach et al., , 2003Tracey et al., 1997Tracey et al., , 1998Tracey et al., , 2003Jordan et al., 1999;Thourani et al., 1999;Ge et al., 2004Ge et al., , 2006. A 3 AR agonists are attractive as cardioprotective agents because they do not alter systemic hemodynamic parameters in nonrodent species and are effective if administered before the ischemic event or only during reperfusion (Auchampach et al

The Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock 2020 (J‐SSCG 2020), a Japanese‐specific set of clinical practice guidelines for sepsis and septic shock created as revised from J‐SSCG 2016 jointly by the Japanese Society of Intensive Care Medicine and the Japanese Association for Acute Medicine, was first released in September 2020 and published in February 2021. An English‐language version of these guidelines was created based on the contents of the original Japanese‐language version. The purpose of this guideline is to assist medical staff in making appropriate decisions to improve the prognosis of patients undergoing treatment for sepsis and septic shock. We aimed to provide high‐quality guidelines that are easy to use and understand for specialists, general clinicians, and multidisciplinary medical professionals. J‐SSCG 2016 took up new subjects that were not present in SSCG 2016 (e.g., ICU‐acquired weakness [ICU‐AW], post‐intensive care syndrome [PICS], and body temperature management). The J‐SSCG 2020 covered a total of 22 areas with four additional new areas (patient‐ and family‐centered care, sepsis treatment system, neuro‐intensive treatment, and stress ulcers). A total of 118 important clinical issues (clinical questions, CQs) were extracted regardless of the presence or absence of evidence. These CQs also include those that have been given particular focus within Japan. This is a large‐scale guideline covering multiple fields; thus, in addition to the 25 committee members, we had the participation and support of a total of 226 members who are professionals (physicians, nurses, physiotherapists, clinical engineers, and pharmacists) and medical workers with a history of sepsis or critical illness. The GRADE method was adopted for making recommendations, and the modified Delphi method was used to determine recommendations by voting from all committee members. As a result, 79 GRADE‐based recommendations, 5 Good Practice Statements (GPS), 18 expert consensuses, 27 answers to background questions (BQs), and summaries of definitions and diagnosis of sepsis were created as responses to 118 CQs. We also incorporated visual information for each CQ according to the time course of treatment, and we will also distribute this as an app. The J‐SSCG 2020 is expected to be widely used as a useful bedside guideline in the field of sepsis treatment both in Japan and overseas involving multiple disciplines.

PMCT is useful for evaluating complications related to chest compression. Further investigations with PMCT are needed to reduce complications and improve the quality of CPR.

ABSTRACT-Supplemental doses of antithrombin (AT) are widely used to treat sepsis-induced disseminated intravascular coagulation (DIC) in Japan. However, evidence on the benefits of ATsupplementation for DIC is insufficient. This multicenter retrospective observational study aimed to clarify the effect of AT supplementation on sepsis-induced DIC using propensity score analyses. Data from 3,195 consecutive adult patients admitted to 42 intensive care units for severe sepsis treatment were retrospectively analyzed; 1,784 patients were diagnosed with DIC (n ¼ 715, AT group; n ¼ 1,069, control group). Inverse probability of treatment-weighted propensity score analysis indicated a statistically significant association between AT supplementation and lower in-hospital all-cause mortality (n ¼ 1,784, odds ratio [95% confidence intervals]: 0.748 [0.572-0.978], P ¼ 0.034). However, quintile-stratified propensity score analysis (n ¼ 1,784, odds ratio: 0.823 [0.646-1.050], P ¼ 0.117) and propensity score matching analysis (461 matching pairs, odds ratio: 0.855 [0.649-1.125], P ¼ 0.263) did not show this association. In the early days after intensive care unit admission, the survival rate was statistically higher in the propensity score-matched AT group than in the propensity score-matched control group (P ¼ 0.007). In DIC patients without concomitant heparin administration, similar results were observed. In conclusion, AT supplementation may be associated with reduced in-hospital all-cause mortality in patients with sepsis-induced DIC. However, the statistical robustness of this connection was not strong. In addition, although the number of transfusions needed in patients with AT supplementation increased, severe bleeding complications did not.
