Histologic Features of Liver Injury Associated With SARS-CoV-2 Messenger RNA Vaccines.

Context.—: Many drugs can induce liver injury; however, vaccine-induced liver injury is a rare phenomenon. SARS-CoV-2 messenger RNA (mRNA) vaccines are now widely administered, and clinical evidence of liver injury has been reported.

Cancer Cell Line Inhibition by Osmotic Pump-administered Xylitol in a Syngeneic Mouse Model.

Background: This study aimed to evaluate the effects of continuous administration of xylitol (a commonly used dental prebiotic) via a subcutaneous osmotic minipump in a B16F10 syngeneic mouse model.

Methods: The B16F10 syngeneic model consisted of 6-8-week-old C57BL/6 male mice subcutaneously injected with five × 10 B16F10 cells suspended in 100 μl PBS in the right flank. The mice were randomly assigned to two groups: Group 1 was the treatment group with 10% xylitol-loaded pumps (n=10), while Group 2 was the control group with saline-loaded pumps (n=10).

Modeling diabetic endothelial dysfunction with patient-specific induced pluripotent stem cells.

Diabetes is a known risk factor for various cardiovascular complications, mediated by endothelial dysfunction. Despite the high prevalence of this metabolic disorder, there is a lack of in vitro models that recapitulate the complexity of genetic and environmental factors associated with diabetic endothelial dysfunction. Here, we utilized human induced pluripotent stem cell (iPSC)-derived endothelial cells (ECs) to develop in vitro models of diabetic endothelial dysfunction.

Worldwide expert recommendations for the diagnosis and management of vitiligo: Position statement from the International Vitiligo Task Force Part 1: towards a new management algorithm.

Background: The treatment of vitiligo can be challenging and depends on several factors such as the subtype, disease activity, vitiligo extent, and treatment goals. Vitiligo usually requires a long-term approach. To improve the management of vitiligo worldwide, a clear and up-to-date guide based on international consensus with uniform stepwise recommendations is needed.

Addition of rituximab in relapsed/refractory chronic lymphocytic leukemia after progression on venetoclax monotherapy.

Venetoclax is approved as monotherapy and in combination with rituximab for relapsed/refractory (R/R) chronic lymphocytic leukemia (CLL). Two Phase 1 studies (M12-175 [NCT01328626]; M13-365 [NCT01682616]) were conducted in which patients who initially responded and then progressed on venetoclax monotherapy could receive added rituximab. Ten patients were evaluated (M12-175, n = 8; M13-365, n = 2), and five (50%) responded again upon addition of rituximab, including three complete and two partial responses.

Prostate cancer extracellular vesicles mediate intercellular communication with bone marrow cells and promote metastasis in a cholesterol-dependent manner.

Primary tumours can establish long-range communication with distant organs to transform them into fertile soil for circulating tumour cells to implant and proliferate, a process called pre-metastatic niche (PMN) formation. Tumour-derived extracellular vesicles (EV) are potent mediators of PMN formation due to their diverse complement of pro-malignant molecular cargo and their propensity to target specific cell types (Costa-Silva et al., 2015; Hoshino et al.

Prostate Cancer Foundation Hormone-Sensitive Prostate Cancer Biomarker Working Group Meeting Summary.

Androgen deprivation therapy remains the backbone therapy for the treatment of metastatic hormone-sensitive prostate cancer (mHSPC). In recent years, several treatments, including docetaxel, abiraterone + prednisone, enzalutamide, and apalutamide, have each been shown to demonstrate survival benefit when used upfront along with androgen deprivation therapy. However, treatment selection for an individual patient remains a challenge.

Development of Treatments for Localized Prostate Cancer in Patients Eligible for Active Surveillance: U.S. Food and Drug Administration Oncology Center of Excellence Public Workshop.

Purpose: The following is a summary of discussion at a United States FDA (Food and Drug Administration) public workshop reviewing potential trial designs and end points to develop therapies to treat localized prostate cancer.

Materials And Methods: The workshop focused on the challenge that drug and device development to treat localized prostate cancer has been limited by the large trial sizes and lengthy timelines required to demonstrate an improvement in overall or metastasis-free survival and by the lack of agreed on alternative end points. Additionally, evolving treatment paradigms in the management of localized prostate cancer include the widespread use of active surveillance of patients with low and some intermediate risk prostate cancer, and the availability of advances in imaging and genomics.

Cancer Drug Toxicity: Moving from Patient to Survivor.

Millions of individuals worldwide are living with cancer and have remained disease-free for more than 5 years. These individuals are considered to be cancer survivors. The advent of new targeted therapies and personalized treatment modalities have contributed to this increased survivorship.

Biosimilars: Are They Really Safe?

An increasing availability of biosimilars is an important step in the process of delivering optimal care while improving access for patients with cancer. Evolving regulatory mechanisms deal with biosimilars with different approaches within major regulatory agencies. We discuss some of the specific properties of biosimilars that merit attention in terms of optimizing their safety, delivering on appropriate related cost savings, and ensuring that appropriate premiums on innovative research are available to ensure ongoing progress in anticancer therapy.

Lysate of engineered Escherichia coli supports high-level conversion of glucose to 2,3-butanediol.

Cell-free metabolic engineering (CFME) is emerging as a powerful approach for the production of target molecules and pathway debugging. Unfortunately, high cofactor costs, limited cofactor and energy regeneration, and low volumetric productivities hamper the widespread use and practical implementation of CFME technology. To address these challenges, we have developed a cell-free system that harnesses ensembles of catalytic proteins prepared from crude lysates, or extracts, of cells to fuel highly active heterologous metabolic conversions.

Characteristics of individuals with breast cancer rearrangements in BRCA1 and BRCA2.

Background: Large rearrangements in BRCA1 and BRCA2 occur in a small percentage (< 1%) of patients tested for hereditary breast (BC) and ovarian cancer. It is unclear what factors predict BRACAnalysis Large Rearrangement Test (BART) positivity.

Methods: Data from 6 centers were included in this analysis.

Diamond-lipid hybrids enhance chemotherapeutic tolerance and mediate tumor regression.

Self-assembled nanodiamond-lipid hybrid particles (NDLPs) harness the potent interaction between the nanodiamond (ND)-surface and small molecules, while providing a mechanism for cell-targeted imaging and therapy of triple negative breast cancers. Epidermal growth factor receptor-targeted NDLPs are highly biocompatible particles that provide cell-specific imaging, promote tumor retention of ND-complexes, prevent epirubicin toxicities and mediate regression of triple negative breast cancers.

ISGIO's Role in the Global Advancement of GI Oncology: Will We be Ready for the Future?

As the world's population expands, the need for GI oncologists will become critical. Unless new paradigms of clinical research are explored, the prospects of making important inroads in curing disease seem remote. What steps can ISGIO take to ensure that the future needs of GI oncology are met and patient access to quality care ensured? ISGIO President Al B.
