Uptitration of Sacubitril/Valsartan and Outcomes in Patients With Heart Failure - Insight From the REVIEW-HF Registry.

Background: Guideline-directed medical therapy has become an important component of heart failure (HF) therapy, with sacubitril/valsartan as one of the recommended drugs; however, the real-world prognostic implications of sacubitril/valsartan uptitration are unclear.

Methods And Results: Patients with HF newly initiated on sacubitril/valsartan were registered in a retrospective multicenter study (REVIEW-HF). In all, 995 patients were divided into 3 groups according to the maximum dose achieved: high dose, sacubitril/valsartan 400 mg; intermediate dose, sacubitril/valsartan 200-<400 mg; and low dose, sacubitril/valsartan <200 mg.

Risk stratification by renal function and NYHA class in patients with hypotension initiated on sacubitril/valsartan: a retrospective cohort study from 17 centres in Japan.

Background: Patients with heart failure exhibiting low systolic blood pressure (SBP) have a poor prognosis. Sacubitril/valsartan reduces cardiovascular events; however, its use in patients with low SBP has not been fully examined. Therefore, in this study, we aimed to investigate the association between baseline SBP and adverse events (AEs) in patients starting sacubitril/valsartan therapy using data from a real-world registry in Japan.

Escherichia coli persisters in biofilm can perform horizontal gene transfer by transformation.

Persisters represent a subset of cells that exhibit transient tolerance to antimicrobials. These persisters can withstand sudden exposure to antimicrobials, even as the majority of normal cells perish. In this study, we have demonstrated the capacity of ampicillin-tolerant and alkali-tolerant persisters to execute horizontal gene transfer via in situ transformation within biofilms.

This study investigated the association between vascular endothelial function and stroke incidence in the general Japanese population.

Vacuolar-ATPase-mediated muscle acidification caused muscular mechanical nociceptive hypersensitivity after chronic stress in rats, which involved extracellular matrix proteoglycan and ASIC3.

Although widespread pain, such as fibromyalgia, is considered to have a central cause, peripheral input is important. We used a rat repeated cold stress (RCS) model with many characteristics common to fibromyalgia and studied the possible involvement of decreased muscle pH in muscle mechanical hyperalgesia. After a 5-day RCS, the muscle pH and the muscular mechanical withdrawal threshold (MMWT) decreased significantly.

Increased nociceptive behaviors and spinal c-Fos expression in the formalin test in a rat repeated cold stress model.

Repeated cold stress (RCS) can trigger the development of fibromyalgia (FM)-like symptoms, including persistent deep-tissue pain, although nociceptive changes to the skin have not been fully characterized. Using a rat RCS model, we investigated nociceptive behaviors induced by noxious mechanical, thermal, and chemical stimuli applied to plantar skin. Neuronal activation in the spinal dorsal horn was examined using the formalin pain test.
