Article Synopsis
  • Medical imaging, especially digital pathology, is transforming cancer diagnosis and treatment by providing detailed cellular-level images.
  • Recent advancements in deep learning have improved the segmentation of tumor regions, highlighting the need for new statistical models to describe tumor shapes instead of relying on outdated traditional methods.
  • This paper introduces a Bayesian model that analyzes tumor boundaries as polygonal chains, effectively estimating landmark uncertainty and quantifying boundary roughness, which was found to significantly predict patient prognosis in lung cancer cases.

Alternating magnetic fields (AMF) and linezolid reduce Staphylococcus aureus biofilm in a large animal implant model.

J Infect

November 2024

Department of Internal Medicine, Infectious Diseases and Geographic Medicine, University of Texas Southwestern Medical Center, Dallas, TX, 75390, USA; Department of Microbiology, University of Texas Southwestern Medical Center, Dallas, TX 75390, USA. Electronic address:

Objectives: We aimed to evaluate the effectiveness of alternating magnetic fields (AMF) combined with antibiotics in reducing Staphylococcus aureus biofilm on metal implants in a large animal model, compared to antibiotics alone.

Methods: Metal plates were inoculated with a clinical MRSA strain and then implanted into thirty-three ewes divided into three groups: positive control, linezolid only, and a combination of linezolid and AMF. Animals had either titanium or cobalt-chrome plates and were sacrificed at 5 or 21 days post-implantation.

Nucleic Acid Therapy for the Skin.

J Invest Dermatol

September 2024

Department of Dermatology, The University of Texas Southwestern Medical Center, Dallas, Texas, USA; Harold C. Simmons Comprehensive Cancer Center, The University of Texas Southwestern Medical Center, Dallas, Texas, USA.

Advances in sequencing technologies have facilitated the identification of the genes and mechanisms for many inherited skin diseases. Although targeted nucleic acid therapeutics for diseases in other organs have begun to be deployed in patients, the goal of precise therapeutics for skin diseases has not yet been realized. First, we review the current and emerging nucleic acid-based gene-editing and delivery modalities.

Metastatic renal cell carcinoma (RCC) can present with oligometastatic disease and/or develop oligoprogression following systemic therapy. Cytoreductive and focal metastasis-directed therapy options include resection, stereotactic ablative radiation and thermal ablation. Aggressive focal therapy may allow delay in initiation of or modification to systemic therapy and improve clinical outcomes.

The correct description of quantum scattering places the observed scattering contributions on the Ewald's sphere and its Friedel mate. In electron microscopy, due to the large radius of the Ewald's sphere, these contributions are typically merged during data analysis. We present an approach that separates and factorizes these contributions into inversion-symmetric and inversion-antisymmetric components.

Background: Sodium glucose cotransporter 2 inhibitors (SGLT2i) prevent heart failure (HF) in patients with type 2 diabetes mellitus (T2DM) but prescription rates are low. The effect of an electronic health record (EHR) alert notifying providers of patients' estimated risk of developing HF on SGTL2i prescriptions is unknown.

Methods: This was a pragmatic, randomized clinical trial that compared an EHR alert and usual care among patients with T2DM and no history of HF or SGLT2i use at a single center.

Background: Choroid plexus (ChP) enlargement is an emerging radiological biomarker in multiple sclerosis (MS).

Objectives: This study aims to assess ChP volume in a large cohort of patients with radiologically isolated syndrome (RIS) versus healthy controls (HC) and explore its relationship with other brain volumes, disease activity, and biological markers.

Methods: RIS individuals were included retrospectively and compared with HC.

Article Synopsis
  • - The text discusses the lack of strong clinical evidence in the critical care of ECMO patients with acute brain injury (ABI) and presents guidelines for their neurological care.
  • - Guidelines were developed using input from an international panel of 30 ECMO experts through a structured voting process, focusing on five key clinical areas.
  • - The consensus emphasizes the importance of early detection and intervention for ABI in ECMO patients to improve health outcomes and outlines multiple recommendations to guide clinical practice and highlight research needs.

The evolving world of the urinary microbiome.

Curr Opin Urol

November 2024

Department of Biological Sciences, The University of Texas at Dallas, Richardson.

Purpose Of Review: The existence of urinary microbiome in healthy individuals is now widely accepted as the longstanding belief in urinary tract sterility was disproved over a decade ago. The urinary microbiome has since been implicated in multiple urologic conditions including urinary tract infection (UTI), urinary incontinence, and bladder cancer. This review relays new findings of urinary microbiome compositional changes associated with aging and UTI susceptibility.

Introduction: Disparities in incidence and outcome of rectal cancer are multifactorial in etiology but may be due, in part, to differences in gut microbiome composition. We used serial robust statistical approaches to assess baseline gut microbiome composition in a diverse cohort of patients with rectal cancer receiving definitive treatment.

Methods: Microbiome composition was compared by age at diagnosis (< 50 vs ≥ 50 years), race and ethnicity (White Hispanic vs non-Hispanic), and response to therapy.

Quantification of Dosimetry Improvement With or Without Patient Surface Guidance.

Adv Radiat Oncol

September 2024

Klinikum Darmstadt GmbH, Institut für Radionkologie und Strahlentherapie, Darmstadt, Germany.

Purpose: Noncoplanar beams and arcs are routinely used to improve dosimetry for intracranial cases, but their application for extracranial cases has been hampered by the risk of collision. This has led to conservative beam selection whose impact on plan dosimetry has not been previously studied.

Methods And Materials: A full-body 3-dimensional patient surface was acquired using optical cameras for a single lung patient at the time of computed tomography simulation.

The radiologically isolated syndrome is defined by the presence of incidentally identified T2-weighted hyperintense lesions, highly suggestive of central nervous system demyelination, following an MRI study that is performed for reasons other than for the investigation of symptoms related to multiple sclerosis (MS). These individuals also have no evidence of prior neurological symptoms associated with inflammatory demyelination and no alternative explanation for the observed MRI findings. Recently, the introduction of novel imaging techniques such as the "central vein sign" has improved lesion specificity for MS.

Targeting Meis1 and Hoxb13 transcriptional activity could be a viable therapeutic strategy for heart regeneration. In this study, we performd an in silico screening to identify FDA-approved drugs that can inhibit Meis1 and Hoxb13 transcriptional activity based on the resolved crystal structure of Meis1 and Hoxb13 bound to DNA. Paromomycin (Paro) and neomycin (Neo) induced proliferation of neonatal rat ventricular myocytes in vitro and displayed dose-dependent inhibition of Meis1 and Hoxb13 transcriptional activity by luciferase assay and disruption of DNA binding by electromobility shift assay.
