Article Abstract
Bronchoscopic biopsy results for indeterminate pulmonary nodules remain suboptimal. Electromagnetic navigation bronchoscopy (ENB) coupled with cone beam computed tomography (CBCT) for confirmation has the potential to improve diagnostic yield. We present our experience using this multimodal approach to biopsy 17 indeterminate nodules in 14 consecutive patients from April to August 2021. Demographic information, nodule characteristics, and biopsy results were recorded. Procedures were performed in a hybrid operating room equipped with a Siemens Artis Q bi-plane CBCT (Siemens, Munich, Germany). After ENB using the superDimension version 7.1 (Medtronic, Plymouth, MN, USA) to target the lesion, radial endobronchial ultrasound was used as secondary confirmation. Next, transbronchial needle aspiration was performed prior to CBCT to evaluate placement of the biopsy tool in the lesion. The average nodule size was 21.7+/−15 mm with 59% (10/17) < 2 cm in all dimensions and 35% (6/17) showing a radiographic bronchus sign. The diagnostic yield of CBCT-guided ENB was 76% (13/17). No immediate periprocedural or postprocedural complications were identified. Our experience with CBCT-guided ENB further supports the comparable efficacy and safety of this procedure compared to other mature biopsy modalities. Studies designed to optimize the lung nodule biopsy process and to determine the contributions from different procedural aspects are warranted.

Adoptive transfer of third-party donor CMV-specific T cells for refractory cytomegalovirus infection following umbilical cord blood transplantation.

Refractory cytomegalovirus (CMV) infection is a severe complication following umbilical cord blood transplantation (UCBT). Antiviral agents, the standard first-line therapy, are limited by toxicity and resistance without robust T-cell immunity. We evaluated third-party donor (TPD)-derived CMV-specific T cells (CMVSTs) as a treatment option.

Background: Bullous pemphigoid (BP) is a common autoimmune subepidermal bullous disease. Dupilumab, an IL-4/IL-13 inhibitor, represents a novel therapeutic approach for BP, but real-world long-term data in super-elderly patients are limited.
Methods: This retrospective, single-center observational study included super-elderly BP patients (≥80 years) receiving dupilumab monotherapy from September 2022 to September 2024.
The trial design of the concurrent optical and magnetic stimulation (COMS) therapy study for refractory diabetic foot ulcers (MAVERICKS): a multicenter, randomized, sham-controlled, double-blind investigational device exemption clinical study.

Background: Diabetic foot ulcers (DFUs) are a major clinical challenge, particularly among patients with refractory ulcers, that often lead to severe complications such as infection, amputation, and high mortality. Innovations supported by strong clinical evidence have the potential to improve healing outcomes, enhance quality of life, and reduce the economic burden on individuals and health care systems.
Objective: To describe the design of the concurrent optical and magnetic stimulation (COMS) therapy Investigational Device Exemption (IDE) study for refractory DFUs (MAVERICKS) trial.
Biodegradation of patulin in apple juice by phosphoribosyl transferase (URA5): implications for food safety.

Patulin (PAT), a mycotoxin produced primarily by Penicillium expansum, poses significant health risks and frequently contaminates apples and apple-derived products, often exceeding permissible safety limits. This study investigated the potential of orotate phosphoribosyl transferase (URA5) to degrade PAT in apple juice under controlled conditions. PAT degradation was assessed at initial concentrations of 100 µg/L and 250 µg/L, with enzymatic treatment using 0.

Purpose: Limited data is available assessing sequencing of antibody drug conjugates (ADCs) in patients with hormone receptor-positive (HR +), human epidermal growth factor 2 (HER2)-negative, HER2-low, and triple-negative metastatic breast cancer (MBC), including patients with brain metastases (BrM) or leptomeningeal disease (LMD). This study assesses the efficacy and safety of sequential sacituzumab govitecan (SG) and trastuzumab deruxtecan (T-DXd) in MBC and impact on chemotherapy (CTX).
Methods: This is a single-center, retrospective, cohort study in adult patients with HR + , HER2-negative, or low MBC who received T-DXd and/or SG.
