Objective: To investigate whether a capsule containing Clostridium butyricum , 3-(4-hydroxy-3-methoxyphenyl) propionic acid (HMPA), and salmon milt-derived DNA improves cognitive function in middleaged and older adults with subjective memory complaints.
Method: This 12-week randomized, double-blind, placebo-controlled trial enrolled 80 adults aged 55-79 years with subjective memory complaints and MMSE-J ≥ 24. Participants received Test food or Placebo once daily. The primary outcome was cognitive function assessed by Cognitrax. Secondary/exploratory outcomes included bowel habits, biochemical parameters, and safety. Efficacy was evaluated in the per-protocol set (n=74), and safety was evaluated in the full analysis set (n=80). An exploratory subgroup comprised participants aged ≥ 65 years with baseline MMSE-J scores of 24-27.
Results: Overall, no consistent between-group differences were observed in memory-related Cognitrax outcomes, but Symbol Digit Coding correct responses improved significantly in the Test food group. In the exploratory subgroup, Verbal Memory and Verbal Memory delayed correct hits improved significantly, whereas Symbol Digit Coding errors decreased significantly, versus Placebo. Bowel habit indices did not improve. Exploratory analyses suggested favorable changes in fasting glucose, HbA1c, gamma-glutamyl transferase (γ-GT), and uric acid. No serious adverse events or product-related side effects occurred.
Conclusion: The Test food did not show consistent overall memory-related benefit, but improved an attentionrelated index and, in a cognitively high-risk subgroup, improved verbal memory-related outcomes while an attention-related subtest score decreased. Together with unchanged bowel indices and favorable exploratory changes in selected metabolic markers, these findings suggest that metabolic changes may be involved, at least in part, in the observed cognitive effects.

Short-Term Safety of Finerenone in Elderly Patients with HFpEF: A Single-Center Retrospective Observational Study Including Patients Receiving Concomitant SGLT2 Inhibitors
目的:左室駆出率の保たれた心不全(HFpEF)に対する治療選択肢は依然として限られている。非ステロイド型ミネラルコルチコイド受容体拮抗薬であるフィネレノンは心腎保護効果を有することが報告されているが,高齢HFpEF 患者における実臨床での安全性データは十分ではない。本研究では,高齢HFpEF患者におけるフィネレノン導入後の短期安全性および臨床指標への影響を検討した。
方法:当院にてフィネレノンを新規導入したHFpEF患者23例を対象とした単施設後ろ向き観察研究である。平均年齢は78.2±8.4歳,baseline eGFRは43.3 mL/min/1.73 m2であった。SGLT2阻害薬併用率は78.3%であった。主要評価項目は有害事象による投与中止率とし,副次評価項目として投与前後1~2カ月におけるNT-proBNP,eGFR,血清K値,Hb,尿酸値の変化を評価した。また,投与前NT-proBNP中央値(729 pg/mL)を用いて2群に分け,BNP変化度について比較検討を行った。
結果:23例中1例(4.3%)で有害事象による投与中止を認めた。中止例では導入時eGFR42 mL/min/1.73 m2,血清K値4.0 mEq/Lであり,腎機能悪化および血清K値上昇を契機に中止となった。全体ではNT-proBNP は918.9 pg/mLから784.3 pg/mLへ有意に低下した(p<0.05)。eGFRは43.3から40.4 mL/min/1.73 m2へ有意に低下した(p<0.05)が,血清K値上昇は軽度であった。さらに,baseline NT-proBNP高値群では低値群と比較してΔNT-proBNPが有意に大きかった(280.7 pg/mL vs 0.75 pg/mL, p<0.05)。
結論:高齢HFpEF患者においてフィネレノンは,SGLT2阻害薬併用下でも短期的に概ね良好な忍容性を示した。また,baseline NT-proBNP高値群においてより大きなBNP 低下を認めており,うっ血や神経体液性活性化が強い症例ほどフィネレノンの反応性が高い可能性が示唆された。
