Mid-Term Prognosis After Landiolol Treatment in Atrial Fibrillation/Atrial Flutter Patients With Chronic Heart Failure - A Prospective Observational Survey (AF-CHF Landiolol Survey).

The aim of the prospective post-marketing AF-CHF Landiolol Survey was to evaluate the safety and effectiveness of landiolol for the treatment of atrial fibrillation or atrial flutter in patients with cardiac dysfunction in clinical practice in Japan. This analysis reports mid-term prognoses with a focus on switching from landiolol to oral β-blockers. The AF-CHF Landiolol Survey took place between June 2014 and May 2016 and involved 1,121 patients with cardiac dysfunction and atrial fibrillation/atrial flutter.

The effects of early life stress on the excitatory/inhibitory balance of the medial prefrontal cortex.

Aversive environmental conditions during early life are known to cause long-lasting social deficits, similar to those observed in patients with neurodevelopmental disorders. However, the mechanism of how early life stress can cause social deficits is not well understood. To clarify how being in an aversive environment during development affects sociability, we conducted various analyses focusing on the excitatory and inhibitory (E/I) balance in the medial prefrontal cortex (mPFC) and how it is related to social deficits, with young adult male rats that had been exposed to maternal separation (MS).

A prospective observational survey on landiolol in atrial fibrillation/atrial flutter patients with chronic heart failure - AF-CHF landiolol survey.

Background: Atrial fibrillation and atrial flutter occur commonly in patients with heart failure. Ultrashort-acting β-blockers, including landiolol, can rapidly control heart rate. As part of postmarketing surveillance for landiolol in Japan, a real-world drug-use survey (AF-CHF landiolol survey) was established for the treatment of atrial fibrillation and atrial flutter in patients with heart failure.

Tocotrienol improves learning and memory deficit of aged rats.

To define whether tocotrienol (T-3) improves cognitive deficit during aging, effect of T-3 on learning and memory functions of aged rats was assessed. It was found that T-3 markedly counteracts the decline in learning and memory function in aged rats. Quantitative analysis of T-3 content in the rat brain showed that the aged rats fed T-3 mixture-supplemented diet revealed the transport of α- and γ-T-3 to the brain.

Consumption of partially hydrolysed guar gum stimulates Bifidobacteria and butyrate-producing bacteria in the human large intestine.

Partially hydrolysed guar gum (PHGG) is a water-soluble dietary fibre that is non-digestible in the upper gastrointestinal tract. It is believed that PHGG benefits the health of hosts by altering the colonic microbiota and stimulating short-chain fatty acid (SCFA) production. However, it remains unclear which bacteria ferment PHGG in the human large intestine.
