Robotic Versus Open Placement of Hepatic Artery Infusion Pumps.

Background: A growing number of centers offer hepatic artery infusion pump (HAIP) chemotherapy for advanced liver malignancies. While small series have demonstrated feasibility of robotic HAIP placement, comparison of outcomes with open placement is lacking. We compared outcomes after robotic versus open HAIP placement.

Evaluation of Bone Mineral Metabolism in Pre-Dialysis Chronic Kidney Disease: Quantitative Computed Tomography vs. Dual-Energy Absorptiometry and Correlation with Bone Turnover Markers.

: Bone and mineral disease (BMD) is a prevalent complication of advanced chronic kidney disease (CKD). The risk of fractures can be assessed via dual-energy X-ray absorptiometry (DXA) and quantitative computed tomography (QCT). This study aims to evaluate the effectiveness of two imaging modalities in identifying bone mineral status in individuals with pre-dialysis chronic renal disease and to assess their correlation with bone turnover markers.

IL-33-activated ILC2s induce tertiary lymphoid structures in pancreatic cancer.

Tertiary lymphoid structures (TLSs) are de novo ectopic lymphoid aggregates that regulate immunity in chronically inflamed tissues, including tumours. Although TLSs form due to inflammation-triggered activation of the lymphotoxin (LT)-LTβ receptor (LTβR) pathway, the inflammatory signals and cells that induce TLSs remain incompletely identified. Here we show that interleukin-33 (IL-33), the alarmin released by inflamed tissues, induces TLSs.

PET-CT-based host metabolic (PETMet) features are associated with pathologic response in gastroesophageal adenocarcinoma.

Background: F-FDG PET-CT-based host metabolic (PETMet) profiling of non-tumor tissue is a novel approach to incorporate the patient-specific response to cancer into clinical algorithms.

Materials And Methods: A prospectively maintained institutional database of gastroesophageal cancer patients was queried for pretreatment PET-CTs, demographics, and clinicopathologic variables. F-FDG PET avidity was measured in 9 non-tumor tissue types (liver, spleen, 4 muscles, 3 fat locations).

Correlation Between Grade of Clinical Response to Neoadjuvant Therapy for Rectal Cancer and Oncologic Outcomes in the Era of Watch-and-Wait.

Background: The watch-and-wait strategy provides an opportunity to pursue non-operative management in rectal cancer patients with clinical complete response after neoadjuvant therapy. The management of those with near complete response remains controversial.

Objective: We assessed the oncologic outcomes of patients managed by watch-and-wait versus total mesorectal excision according to clinical response to neoadjuvant therapy.

Optimizing Care for Primary Glomerulonephritis: The Role of Thyroid Evaluation.

Background: The coexistence of primary glomerulonephritis and autoimmune thyroid disease has not been investigated.

Objective: This study aimed to assess thyroid morphology using sonography, determine the prevalence of autoimmune thyroid disorders, and evaluate thyroid function status in patients diagnosed with primary glomerulonephritis.

Materials And Methods: This single-center cross-sectional and observational study included 58 consecutive patients with primary glomerulonephritis and 58 healthy controls (HC).

Prediction of checkpoint inhibitor immunotherapy efficacy for cancer using routine blood tests and clinical data.

Predicting whether a patient with cancer will benefit from immune checkpoint inhibitors (ICIs) without resorting to advanced genomic or immunologic assays is an important clinical need. To address this, we developed and evaluated SCORPIO, a machine learning system that utilizes routine blood tests (complete blood count and comprehensive metabolic profile) alongside clinical characteristics from 9,745 ICI-treated patients across 21 cancer types. SCORPIO was trained on data from 1,628 patients across 17 cancer types from Memorial Sloan Kettering Cancer Center.

Voxel-Based Dosimetry Predicts Local Tumor Progression Post 90 Y Radiation Segmentectomy of Colorectal Liver Metastases.

Background: Radiation segmentectomy (RS) is an alternative potential local curative treatment for selected colorectal liver metastases (CLMs) not amenable to ablation or limited resection.

Purpose: The aim of this study was to evaluate the dosimetric response of low volume CLMs to RS in heavily pretreated patients who are not candidates for resection or percutaneous ablation.

Patients And Methods: This single-center retrospective study evaluated CLMs patients treated with RS (prescribed tumor dose >190 Gy) from 2015 to 2023.

Evaluation of the Ki-67 labeling index on immediate pre-ablation biopsies as a predictive biomarker of local recurrence of colorectal cancer liver metastases.

The aim of this study was to evaluate if the Ki-67 labeling index (LI) on immediate pre-ablation biopsies of colorectal liver metastases (CLM) is associated with the presence of viable tumor cells in subsequent ablation zone biopsies and/or local tumor progression-free survival (LTPFS). Biopsies of CLM were performed before and after microwave ablation (MWA), as part of a prospective clinical trial between October 2013 and May 2019. Pre-ablation biopsy slides were examined for the Ki-67 LI using light microscopy.

Impact of Financial Toxicity on Treatment Adherence and Quality of Life in Pancreatic Cancer.

Purpose: Financial toxicity (FT) is increasingly recognized as a major issue in cancer care. We evaluated the prevalence and risk factors for FT in patients with pancreatic ductal adenocarcinoma (PDAC) and FT associations with treatment adherence and quality of life (QOL).

Methods: A screening questionnaire based on the Comprehensive Score for Financial Toxicity (COST) was implemented at our National Cancer Institute-designated comprehensive cancer center.

Survival of Patients with Resected Microsatellite Instability-High, Mismatch Repair Deficient, and Lynch Syndrome-Associated Pancreatic Ductal Adenocarcinomas.

Background: Pancreatic ductal adenocarcinoma (PDAC) remains a challenging disease due to its aggressiveness, late-stage diagnosis, and limited treatment options. Microsatellite instability-high (MSI-H) cancers are susceptible to immune checkpoint inhibitors. Survival outcomes for patients with MSI-H PDAC are unknown as the disease is rare.

Interferon response and epigenetic modulation by mutations drive ovarian tumor immunogenicity.

Cell-intrinsic mechanisms of immunogenicity in ovarian cancer (OC) are not well understood. Damaging mutations in the SWI/SNF chromatin remodeling complex, such as (BRG1), are associated with improved response to immune checkpoint blockade; however, the mechanism by which this occurs is unclear. We found that loss in OC models resulted in increased cancer cell-intrinsic immunogenicity, characterized by up-regulation of long-terminal RNA repeats, increased expression of interferon-stimulated genes, and up-regulation of antigen presentation machinery.

Enhanced Cycling Stability of Al-Doped LiMn Al NiCoO as a Cathode Material for Li-Ion Batteries by a Supercritical-CO-Assisted Method.

Lithium-rich layered oxide materials (Li-NMC) are considered a potential cathode material for next-generation batteries, thanks to their high theoretical specific capacity. Large potential drop and capacity loss after long cycles are the main obstacles to expanding commercial utilization of Li-NMC. In the past decade, great efforts have been made to overcome those issues of Li-NMCs.

Surgical Site Infections in Simultaneous Colorectal and Liver Resections for Metastatic Colorectal Adenocarcinoma.

Background: Surgical site infections (SSIs) are a major driver of morbidity after combined liver and colorectal surgery for metastatic colorectal cancer. Available literature is inadequate to characterize risk factors and benchmarks for quality improvement.

Methods: Consecutive cases of simultaneous liver and colorectal surgery for colorectal adenocarcinoma from November 2013 through September 2022 were reviewed for SSIs per National Surgical Quality Improvement Program (NSQIP) and National Healthcare Safety Network (NHSN) criteria.

Scalable log-ratio lasso regression for enhanced microbial feature selection with FLORAL.

Identifying predictive biomarkers of patient outcomes from high-throughput microbiome data is of high interest, while existing computational methods do not satisfactorily account for complex survival endpoints, longitudinal samples, and taxa-specific sequencing biases. We present FLORAL, an open-source tool to perform scalable log-ratio lasso regression and microbial feature selection for continuous, binary, time-to-event, and competing risk outcomes, with compatibility for longitudinal microbiome data as time-dependent covariates. The proposed method adapts the augmented Lagrangian algorithm for a zero-sum constraint optimization problem while enabling a two-stage screening process for enhanced false-positive control.

C1 Root Decompression as a Therapeutic Target in Non-Suboccipital Non-Valsalva Related Headache Associated with Chiari I Malformation.

Background: Headache (HA) is the most common symptom impacting the quality of life of patients with Chiari I malformation. While HAs typically present in the occipital or suboccipital regions, and induced by Valsalva maneuver, complex migraine-like HAs referring to frontal or orbital regions also occur. Our study explores the therapeutic potential of C1 nerve root decompression in addition to increasing intracranial compliance in patients with Chiari I malformation.

Deformable Mapping of Rectal Cancer Whole-Mount Histology with Restaging MRI at Voxel Scale: A Feasibility Study.
