Background: Traumatic injury leads to gut dysbiosis with changes in microbiome diversity and conversion toward a "pathobiome" signature characterized by a selective overabundance of pathogenic bacteria. The use of non-selective beta antagonism in trauma patients has been established as a useful adjunct to reduce systemic inflammation. We sought to investigate whether beta-adrenergic blockade following trauma would prevent the conversion of microbiome to a "pathobiome" phenotype.

: The development of a five-in-one vaccine microneedle patch (five-in-one MN patch) aims to address challenges in administering vaccines against Diphtheria (DT), Tetanus (TT), Pertussis (wP), Hepatitis B (HBsAg), and type b (Hib). Combining multiple vaccines into a single patch offers a novel solution to improve vaccine accessibility, stability, and delivery efficiency, particularly in resource-limited settings. : The five-in-one MN patch consists of four distinct microneedle arrays: DT and TT vaccines are coated together on one array, while wP, HepB, and Hib vaccines are coated separately on individual arrays.

CD226 plays a vital role in natural killer (NK) cell cytotoxicity, interacting with its ligands CD112 and CD155 to initiate immune synapse formation, primarily through leukocyte function-associated-1 (LFA-1). Our study examined the role of CD226 in NK cell surveillance of acute myeloid leukemia (AML). NK cells in patients with AML had lower expression of CD226.

Article Synopsis
  • Systemic lupus erythematosus (SLE) is a chronic autoimmune disease where hyper-activated B cells produce autoantibodies, causing symptoms.
  • Research found that naïve mesenchymal stem cells (MSCs) inhibit T cell activity but not B cell IgM production, leading to a study on how to enhance MSC function.
  • Treatment with ingenol-3-angelate (I3A) primes MSCs to inhibit B cells through the secretion of TGF-β1, showing improved effectiveness in alleviating SLE symptoms in mice.

  • The study aimed to compare the capabilities of GPT-4 and Gemini, two large language models, in analyzing serial radiology reports to identify oncological issues needing clinical attention.
  • It involved 205 patients with two consecutive radiological reports and used a three-step task for the LLMs, while two radiologists established a six-level categorization of tumor findings as a ground truth.
  • Results indicated that GPT-4 outperformed Gemini in terms of accuracy (96.2% vs 91.7%), precision in identifying tumor-related findings, and correctly determining tumor status, demonstrating the effectiveness of LLMs in oncological surveillance.

  • Atrial fibrillation (AF) often recurs after catheter ablation, and the study investigates how changes in the pulmonary vein (PV) structure, highlighted by artificial intelligence (AI), relate to this recurrence.* -
  • Two AI models were used to analyze CT images from 809 patients, examining features of primary and secondary PV branches to determine their link to AF recurrence post-ablation.* -
  • The findings suggest that morphological features of primary PV branches have a significant association with AF recurrence, indicating potential pathways for improving patient outcomes after ablation.*

Objectives: Concern about contrast-induced acute kidney injury (CI-AKI) may delay the timely administration of contrast media for computed tomography (CT). The precise causative effect of iodinated contrast media on CI-AKI and its relevant risk factors remains an area of ongoing investigation. Therefore, this study aimed to determine the risk of CI-AKI following contrast-enhanced CT and its predisposing risk factors.

Background And Objectives: Parkinson disease (PD) shows degeneration of dopaminergic neurons in the substantia nigra and characteristic changes in brain metabolism. However, how they correlated and affect motor and cognitive dysfunction in PD has not yet been well elucidated.

Methods: In this single-site cross-sectional study, we enrolled patients with PD who underwent -(3-[F]fluoropropyl)-2β-carbomethoxy-3β-(4-iodophenyl)nortropane (F-FP-CIT) PET, F-fluorodeoxyglucose (F-FDG) PET, the Movement Disorder Society-sponsored Unified PD Rating Scale examination, and detailed neuropsychological testing.

Herein we report the first successful synthesis of ethanol-assisted generated reduced graphene oxide as a support for CuO/NiO nanoparticles. Through the strategic incorporation of Cu and Ni precursors into ethanol, followed by thermal treatment, we achieved the fabrication of reduced graphene oxide-supported CuO/NiO nanoparticles. The material underwent thorough characterization using FT-IR, XRD, TEM, XPS, Raman, and UV-DRS analysis.

Purpose: To compare clinical and radiologic outcomes between biceps anchor tenodesis (AT), biceps soft-tissue tenodesis (ST), and biceps tenotomy (TT) for patients with concomitant rotator cuff repair (RCR).

Methods: This retrospective study reviewed patients who underwent arthroscopic RCR for full-thickness rotator cuff tears with AT, ST, or TT with minimum 2-year follow-up. All biceps procedures were performed arthroscopically, and ST consisted of fixation to the transverse humeral ligament.

Background And Purpose: Rescue stent (RS) is an accepted rescue option after failed mechanical thrombectomy (MT) for acute ischemic stroke due to intracranial atherosclerotic stenosis (ICAS)-related large vessel occlusion (LVO). However, the long-term outcomes (≥ 12 months) of RS have not yet been elucidated.

Materials And Methods: We retrospectively analyzed the data of 154 patients with RS for ICAS-related LVO, which were identified from prospectively maintained multicenter database of RS after MT failure, to assess good outcome (mRS 0-2), mortality, stroke recurrence, symptomatic intracranial hemorrhage (SICH) and stent patency.

Aims: Although evaluation of left ventricular ejection fraction (LVEF) is crucial for deciding the rate control strategy in patients with atrial fibrillation (AF), real-time assessment of LVEF is limited in outpatient settings. We aimed to investigate the performance of artificial intelligence-based algorithms in predicting LV systolic dysfunction (LVSD) in patients with AF and rapid ventricular response (RVR).

Methods And Results: This study is an external validation of a pre-existing deep learning algorithm based on residual neural network architecture.

Adrenomyeloneuropathy is a progressive neurodegenerative disease caused by pathogenic variants in the gene, resulting in very-long-chain fatty acid (VLCFA) accumulation that leads to dying-back axonopathy. Our candidate gene therapy, SBT101 (AAV9-human [h]), aims to ameliorate pathology by delivering functional copies of h to the spinal cord. Transduced cells produce functional ABCD1 protein, thereby repairing the underlying biochemical defect.
