  1. randomized trial, 29 patients

    Music-Based Intervention in Postoperative Lung Transplant Care: A Feasibility Study

    Tague DB, Pickett E, Stock CD, et al. J Music Ther. Jul 2026.

    Findings
    In 29 patients, the music‑based group showed lower pain scores and median acetaminophen use, though differences were not statistically significant.
    Bottom line
    Music therapy may reduce pain and analgesic use post‑lung transplant, but larger trials are needed to confirm significance.

    PubMed, PMID 42921809

  2. systematic review, 12 studies

    Probiotics and synbiotics as adjunctive therapies for heart failure: a systematic review with network and pairwise meta-analyses

    Liu Q, Xie H, Lin F, et al. Front Nutr. Jan 2026.

    Findings
    The review of 12 randomized trials (1,021 participants) found a network meta‑analysis mean difference of 2.13 percentage points in left ventricular ejection fraction for multi‑strain probiotics versus control, with a 95% CI of -0.10 to 4.35.
    Bottom line
    Current evidence suggests a modest, statistically uncertain LVEF improvement of 2.13 percentage points with probiotic therapy in heart failure, but confidence is low.

    PubMed, PMID 42889178

  3. prospective cohort, 22 patients

    Myocardial External Efficiency and Energetic Adaptation After Heart Transplantation: An Exploratory Study

    Berg Okholm K, Kjærulff MLG, Berg Hansen K, et al. Transplantation. Oct 2026.

    Findings
    Myocardial external efficiency increased from 18 ± 5% to 21 ± 5% at 6 months after heart transplantation (P = 0.003). It remained below the 26 ± 6% observed in controls (P < 0.0001).
    Bottom line
    Myocardial external efficiency improves after transplantation to 21 ± 5% and correlates with strain (r = -0.49).

    PubMed, PMID 42925569

  4. randomized trial, 328 patients

    Multimodal prehabilitation in colorectal cancer surgery: randomized clinical trial

    Bjerregaard F, Pekkari K, Asklid D, et al. BJS Open. Sep 2026.

    Findings
    In 242 patients undergoing colorectal resection, postoperative complications occurred in 47.5% of the prehabilitation group versus 45.0% of controls, showing no significant benefit. Severe complications affected 19.0% overall, with a non‑significant trend toward fewer in the intervention arm.
    Bottom line
    Multidisciplinary prehabilitation did not reduce complication rates (47.5% vs 45.0%) after colorectal cancer surgery.

    PubMed, PMID 42925093

  5. meta-analysis, 775 patients

    Fetal cardiac interventions versus expectant management in congenital heart disease: a systematic review and meta-analysis

    Ning P, Liu J, Lin S, et al. BMC Pregnancy Childbirth. Jul 2026.

    Findings
    Live birth occurred in 271 of 315 (86.0%) FCI cases and 287 of 319 (90.0%) controls.
    Bottom line
    FCI had 271/315 (86.0%) live births; controls had 287/319 (90.0%).

    PubMed, PMID 42902283

  6. prospective cohort, 80 patients

    Prospective evaluation of donor-derived cell-free DNA for noninvasive detection of acute rejection in an Asian heart transplant population

    Zheng S, Liu S, Zhu Z, et al. Transpl Int. Jan 2026.

    Findings
    In heart transplant recipients, acute rejection patients showed higher dd-cfDNA levels than non-rejection patients (0.87% vs. 0.23%, P < 0.001). An optimal threshold of 0.33% yielded an AUC of 0.874 with 81.0% sensitivity and 85.7% specificity.
    Bottom line
    A dd-cfDNA cut-off of 0.33% offers a useful noninvasive rule-in marker for acute rejection.

    PubMed, PMID 42898121

  7. prospective cohort, 200 patients

    Effectiveness of Nursing Interventions on Stress and Functional Capacity Among Patients After Coronary Artery Bypass Grafting (CABG): A Randomized Controlled Trial

    Singh NV, Kalia R, Singh A, et al. Cureus. Sep 2026.

    Findings
    In a trial of 200 CABG patients, nurse-led interventions significantly reduced stress (p ≤ 0.001) and enhanced functional capacity at three months (p < 0.001).
    Bottom line
    Nurse-led interventions significantly lower psychological stress and improve functional capacity after coronary artery bypass grafting.

    PubMed, PMID 42890438

  8. prospective cohort, 312 patients

    The Prognostic Value of Entropy from T1 Mapping in Pulmonary Arterial Hypertension

    Zhao J, Guo J, He J, et al. J Cardiovasc Magn Reson. Oct 2026.

    Findings
    In 312 patients with pulmonary arterial hypertension, left ventricular entropy ≥8.60 (HR 2.207; 95% CI, 1.324-3.678; P = 0.002) and entropy without IPs ≥8.30 (HR 2.357; 95% CI, 1.405-3.955; P = 0.001) independently predicted all-cause mortality.
    Bottom line
    Left ventricular entropy from T1 mapping provides independent prognostic value for mortality in pulmonary arterial hypertension.
