Cardiovascular Considerations During Cancer Therapy: Gaps in Evidence and Expert Panel Recommendations.

The administration of certain cancer therapies can be associated with the development of cardiovascular toxicity or complications. This spectrum of toxicities is broad and requires nuanced approaches for prevention, identification, and management. This expert panel summarizes the consensus of opinions of diverse health care professionals in several key areas: 1) cardioprotection involves strategies aimed at the primary prevention of cancer therapy-related cardiovascular toxicity; 2) surveillance entails monitoring for cancer therapy-related cardiovascular toxicity during cancer therapy; 3) permissive cardiotoxicity is the informed continuation of cancer therapy in the presence of cardiovascular toxicity, along with the implementation of mitigating cardiovascular treatments; and 4) special considerations include the invasive management of severe cardiovascular disease in patients receiving treatments for advanced cancer and the exploration of drug-drug interactions in cardio-oncology.

Cardiovascular Disease With Hormone Therapy and Ovarian Suppression in Premenopausal Breast Cancer Survivors.

Background: Hormone therapies, including aromatase inhibitors and tamoxifen, are used with ovarian suppression to improve outcomes in premenopausal patients with breast cancer. Cardiovascular impacts of these treatments among premenopausal women are unknown.

Objectives: The aim of this study was to test the hypothesis that the use of aromatase inhibitors in combination with ovarian suppression, relative to tamoxifen, is associated with greater incident cardiovascular disease (CVD) risk in premenopausal breast cancer survivors.

Optimizations of Placenta Extracellular Matrix-Loaded Silk Fibroin/Alginate 3D-Printed Scaffolds Structurally and Functionally for Bone Tissue Engineering.

Recent interest has been focused on extracellular matrix (ECM)-based scaffolds totreat critical-sized bone injuries. In this study, urea was used to decellularize and solubilize human placenta tissue. Then, different concentrations of ECM were composited with 8% alginate (Alg) and 12% silk fibroin (SF) for printing in order to produce a natural 3D construct that resembled bone tissue.

Astrocytes Mediate Psychostimulant-Induced Alterations of Spike-Timing Dependent Synaptic Plasticity.

At cellular and circuit levels, drug addiction is considered a dysregulation of synaptic plasticity. In addition, dysfunction of the glutamate transporter 1 (GLT-1) in the nucleus accumbens (NAc) has also been proposed as a mechanism underlying drug addiction. However, the cellular and synaptic impact of GLT-1 alterations in the NAc remain unclear.

Distinguishing Chronic Inflammatory Demyelinating Polyneuropathy From Mimic Disorders: The Role of Statistical Modeling.

Background And Aims: Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is difficult to distinguish from mimicking disorders, with misdiagnosis resulting in IVIG overutilization. We evaluate a clinical-electrophysiological model to facilitate CIDP versus mimic neuropathy prediction.

Methods: Using the European Academy of Neurology/Peripheral Nerve Society (EAN/PNS) 2021 CIDP guidelines we derived 26 clinical and 144 nerve conduction variables.

Proteomic signature of HIV-associated subclinical left atrial remodeling and incident heart failure.

People living with HIV are at higher risk of heart failure and associated left atrial remodeling compared to people without HIV. Mechanisms are unclear but have been linked to inflammation and premature aging. Here we obtain plasma proteomics concurrently with cardiac magnetic resonance imaging in two independent study populations to identify parallels between HIV-related and aging-related immune dysfunction that could contribute to atrial remodeling and clinical heart failure.

Relationships between adrenal insufficiency and cardiovascular outcomes in patients with congestive heart failure.

Background And Aims: Patients with adrenal insufficiency (AI) face elevated risks during various hospitalizations including cardiovascular related admissions. Despite this, limited data exist specifically regarding congestive heart failure (CHF) in the context of AI. This investigation leveraged a comprehensive national database to examine the association between AI and cardiovascular outcomes among patients admitted with CHF.

Microbiota transplant for hepatic encephalopathy in cirrhosis: The THEMATIC trial.

Background: Preventing hepatic encephalopathy (HE) recurrence in cirrhosis, which is associated with an altered gut-liver-brain axis, is an unmet need. Fecal microbiota transplantation (FMT) is beneficial in phase-1 studies, but route and dose-related questions remain.

Methods: We performed a phase-2 randomized, placebo-controlled, double-blind, clinical trial of capsule and enema FMT in cirrhosis and HE on lactulose and rifaximin.

The Association of HLA-E Ligand and NKG2 Receptor Variation with Relapse and Mortality after Haploidentical Related Donor Transplantation.

Background: Recurrence of blood malignancy is the major cause of mortality after hematopoietic cell transplantation. NKG2 receptor/HLA-E ligand complexes play a fundamental role in the surveillance and elimination of transformed cells but their role in the control of leukemia in transplantation is unknown.

Objective: We tested the hypothesis that gene variation of patient and/or donor HLA-E ligand and donor NKG2C-NKG2A receptors are associated with the risks of relapse and mortality (primary endpoints) and GVHD and non-relapse mortality (secondary endpoints) after haploidentical transplantation.

Suture Anchor Fixation of the Pediatric Posteromedial and Posterolateral Menisco-Tibial Ligament Complex Matches or Exceeds Native Tissue Strength: A Cadaveric Study.

Objectives: To compare the biomechanical strength and stiffness of the native posteromedial and posterolateral meniscotibial ligament complex (MTLC) to suture anchor repair of the MTLC.

Methods: Biomechanical testing was performed on 24 fresh-frozen pediatric human knees. Four conditions were tested: native posteromedial MTLC (n=14), native posterolateral MTLC (n=14), posteromedial MTLC repair (n=5), and posterolateral MTLC repair (n=5).

RAMIE: retrieval-augmented multi-task information extraction with large language models on dietary supplements.

Objective: To develop an advanced multi-task large language model (LLM) framework for extracting diverse types of information about dietary supplements (DSs) from clinical records.

Methods: We focused on 4 core DS information extraction tasks: named entity recognition (2 949 clinical sentences), relation extraction (4 892 sentences), triple extraction (2 949 sentences), and usage classification (2 460 sentences). To address these tasks, we introduced the retrieval-augmented multi-task information extraction (RAMIE) framework, which incorporates: (1) instruction fine-tuning with task-specific prompts; (2) multi-task training of LLMs to enhance storage efficiency and reduce training costs; and (3) retrieval-augmented generation, which retrieves similar examples from the training set to improve task performance.

Protocol for the three-dimensional analysis of rodent skeletal muscle.

Confocal imaging is a powerful tool capable of analyzing cellular spatial data within a given tissue. Here, we present a protocol for preparing optically cleared extensor digitorum longus (EDL) skeletal muscle samples suitable for confocal imaging/computational analysis. We describe steps for sample preparation (including perfusion fixation and tissue clearing of muscle samples), image acquisition, and computational analysis, with sample segmentation/3D rendering outlined.

Digital Solutions for the Optimization of Pharmacologic Therapy for Heart Failure.

Data from large-scale, randomized, controlled trials demonstrate that contemporary treatments for heart failure (HF) can substantially improve morbidity and mortality. Despite this, observed outcomes for patients living with HF are poor, and they have not improved over time. The are many potential reasons for this important problem, but inadequate use of optimal medical therapy for patients with HF, an important component of guideline-directed medical therapy, in routine practice is a principal and modifiable contributor.

Injectable Estradiol Use in Transgender and Gender-Diverse Individuals in the U.S.: A Multicenter Retrospective Study.

Context: Guidelines for use of injectable estradiol esters (valerate [EV] and cypionate [EC]) among transgender and gender diverse (TGD) individuals designated male at birth vary considerably, with many providers noting supraphysiologic serum estradiol concentrations based on current dosing recommendations.

Objectives: 1. Determine dose of injectable estradiol (subcutaneous [SC] and intramuscular [IM]) needed to reach guideline-recommended estradiol concentrations for TGD adults using EC/EV.

Proximity-Ligation Metagenomic Sequence Analysis Reveals That the Antibiotic Resistome Makes Significant Transitions During Municipal Wastewater Treatment.

Shotgun and proximity-ligation metagenomic sequencing were used to generate thousands of metagenome assembled genomes (MAGs) from the untreated wastewater, activated sludge bioreactors, and anaerobic digesters from two full-scale municipal wastewater treatment facilities. Analysis of the antibiotic resistance genes (ARGs) in the pool of contigs from the shotgun metagenomic sequences revealed significantly different relative abundances and types of ARGs in the untreated wastewaster compared to the activated sludge bioreactors or the anaerobic digesters (p < 0.05).

Engineered Cellular Therapies for the Treatment of Thoracic Cancers.

Thoracic malignancies (lung cancers and malignant pleural mesothelioma) are prevalent worldwide and are associated with high morbidity and mortality. Effective treatments are needed for patients with advanced disease. Cell therapies are a promising approach to the treatment of advanced cancers that make use of immune effector cells that have the ability to mediate antitumor immune responses.

A Randomized Pilot Study of Time-Restricted Eating Shows Minimal Microbiome Changes.

Objective: TRE is an emerging approach in obesity treatment, yet there is limited data on how it influences gut microbiome composition in humans. Our objective was to characterize the gut microbiome of human participants before and after a TRE intervention. This is a secondary analysis of a previously published clinical trial examining the effects of time-restricted eating (TRE).

The Impact of Cell-Intrinsic STAT6 Protein on Donor T Cell-Mediated Graft-Versus-Tumor Effect.

Bone marrow transplantation (BMT) is mainly performed to restore an anti-tumor immune response, called the graft-versus-tumor (GVT) effect, against leukemia, myeloma and lymphoma. This GVT reactivity is driven by donor T cells, and it can also cause lethal graft-versus-host disease (GVHD). We previously demonstrated that the colonization of mice with helminths preserves the GVT response while suppressing GVHD.

Cycle Effects Are Not Universal: A Case Study of Urinary C-Reactive Protein Concentrations in Rural Polish and Polish American Samples.

Objectives: We need to better understand how the menstrual cycle interacts with other biological systems, such the inflammation and immune response. One way to study this interaction is through C-reactive protein (CRP). Studies of CRP concentrations across the menstrual cycle have been inconsistent.
