Repurposing Probenecid for the Treatment of Heart Failure (Re-Prosper-HF): a study protocol for a randomized placebo-controlled clinical trial.

Improving contractility in heart failure with reduced ejection fraction has resurfaced as a potential treatment target. An increase in systolic intracellular calcium that has yet to stimulate cAMP manufacturing provides at least two clinically relevant calcitropes-istaroxime and probenecid-improve contractility. Translational studies have shown that it increases calcium cycling and contractility without stimulating noxious pathways associated with cAMP-dependent calcitropes, as well as cardiac function in patients with HFrEF.

Identification of an optimal dose of intravenous ketamine for late-life treatment-resistant depression: a Bayesian adaptive randomization trial.

This study used Bayesian adaptive randomization to determine the optimal dose for treatment response 7 days after a 40 min intravenous infusion of ketamine 0. 1 mg/kg, 0. 25 mg/kg, or 0. 5 mg/kg as an active placebo. A random double-blind was selected for Thirty-three drug-free U. S. military veterans with LL-TRD. The termination of KET 0. 1 and KET 0. 25 for inferiority was determined by a pre-specified decision system. Compared to MID, the posterior probability was 0. 89 that the day-seven treatment response was superior for KET 0. 5 than to MID. Persistent treatment response at day 28 was higher than MID 0. 5 when compared to MID. During infusion, KET 0. 5 displayed a high posterior risk of increased frontal gamma capability and reduced posterior alpha power, leading to an acute rise in E/I ratio. These findings show that 0. 5 mg/kg is an effective first IV ketamine dose in LL-TRD, but further research in people older than 75 is needed.

An Open Trial of a Suicide Safety Planning Group Treatment: "Project Life Force".

Every patient who is listed as a hazard" is identified as a "high risk" for suicide, according to the Department of Veterans Affairs, clinicians must lead the design of a Suicide Safety Plan for every patient who is identified as a "significant risk" for suicide in 2008. Despite some limitations, exploratory findings have indicated that PLF may be a promising treatment for Veterans with suicidal symptoms.

Ketamine metabolites, clinical response, and gamma power in a randomized, placebo-controlled, crossover trial for treatment-resistant major depression.

Several organisations had previously reported that hydroxynorketamine had antidepressant effects in rodents, and that -HNK raised cortical electroencephalographic gamma power. In 34 people with treatment-resistant depression who received a single ketamine infusion over 40 min, this exploratory research investigated the connection between ketamine metabolites, clinical response, psychotomimetic signs, and gamma power changes in 34 people with treatment-resistant depression. At day 11 post-infusion, the ketamine concentration positively predicted distal antidepressant response, and an inverse correlation was observed between the -HNK concentration and antidepressant response at 3 and 7 days post-infusion. HNK's highest observed concentration was seen in third, which was associated with increased MEG gamma power. These exploratory findings replicate those of a recently published study establishing a correlation between higher -HNK levels and weaker antidepressant response in humans, helping to identify gamma power changes as potential antidepressant biomarkers.
