Perspectives of the medical oncologist regarding adjuvant chemotherapy for pancreatic cancer: An international expert survey and case vignette study.

Introduction: Adjuvant chemotherapy improves survival in patients with resected pancreatic ductal adenocarcinoma (PDAC). The decision to initiate chemotherapy involves both patient and physician factors, decision-specific criteria, and contextual considerations. This study aimed to assess medical oncologists' views on adjuvant chemotherapy following pancreatic resection for PDAC.

The composition of commercially available human embryo culture media.

Study Question: What is the composition of currently available commercial human embryo culture media provided by seven suppliers, for each stage of human preimplantation embryo development?

Summary Answer: While common trends existed across brands, distinct differences in composition underlined the absence of a clear standard for human embryo culture medium formulation.

What Is Known Already: The reluctance of manufacturers to fully disclose the composition of their human embryo culture media generates uncertainty regarding the culture conditions that are used for human preimplantation embryo culture. The critical role of the embryo culture environment is well-recognized, with proven effects on IVF success rates and child outcomes, such as birth weight.

Longitudinal multimodal profiling of IDH-wildtype glioblastoma reveals the molecular evolution and cellular phenotypes underlying prognostically different treatment responses.

Background: Despite recent advances in the biology of IDH-wildtype glioblastoma, it remains a devastating disease with median survival of less than 2 years. However, the molecular underpinnings of the heterogeneous response to the current standard-of-care treatment regimen consisting of maximal safe resection, adjuvant radiation, and chemotherapy with temozolomide remain unknown.

Methods: Comprehensive histopathologic, genomic, and epigenomic evaluation of paired initial and recurrent glioblastoma specimens from 106 patients was performed to investigate the molecular evolution and cellular phenotypes underlying differential treatment responses.

Factors affecting the feasibility of post-authorisation RCTs for conditionally authorised anticancer medicines: a multistakeholder perspective from a qualitative focus group study.

Objective: The collection of comprehensive data from post-authorisation trials for conditionally authorised anticancer medicines is frequently delayed. This raises questions about the feasibility of post-authorisation randomised controlled trials (RCTs) that aim to address remaining uncertainties. Therefore, this study explored factors that facilitate or impede the feasibility of post-authorisation RCTs from the perspective of stakeholders directly involved in the design, medical-ethical approval, and conduct of these RCTs.

Successful ACL repair by dynamic intraligamentary stabilisation is non-inferior in functional performance and worse in proprioception compared to healthy controls in a case-matched study.

Purpose: The primary aim of this study was to assess non-inferiority in functional performance of the knee after dynamic intraligamentary stabilisation (DIS) surgery at a minimal follow-up of 1 year compared to healthy controls, based on limb symmetry index (LSI) of the single leg hop test (SLH). Additionally, functional performance based on the single leg triple hop test (SLTH) and side hop test (SH), proprioception and subjective outcome were evaluated.

Methods: A total of 45 DIS patients were 1-to-1 matched to a healthy control.

Chimeric antigen receptor T-cell therapy in patients with malignant glioma-From neuroimmunology to clinical trial design considerations.

Clinical trials evaluating chimeric antigen receptor (CAR) T-cell therapy in patients with malignant gliomas have shown some early promise in pediatric and adult patients. However, the long-term benefits and safety for patients remain to be established. The ultimate success of CAR T-cell therapy for malignant glioma will require the integration of an in-depth understanding of the immunology of the central nervous system (CNS) parenchyma with strategies to overcome the paucity and heterogeneous expression of glioma-specific antigens.

Adjuvant immunotherapy in older patients with stage III and resected stage IV melanoma: Toxicity and recurrence-free survival outcomes from the Dutch melanoma treatment registry.

Background: Adjuvant anti-PD-1 therapy improves relapse free survival in stage III melanoma, but also leads to immune-related adverse events (irAEs). Older patients are of particular interest due to comorbidities and frailty, which may impact their ability to tolerate irAEs and benefit from anti-PD-1 therapy. This study aimed to explore associations between clinical parameters and the occurrence of grade ≥ 3 irAEs and recurrence-free survival (RFS) in older patients with radically resected stage III/IV cutaneous melanoma treated with adjuvant anti-PD-1 therapy.

Prescription and switching patterns of direct oral anticoagulants in patients with atrial fibrillation.

Background: The patterns of direct oral anticoagulant (DOAC) selection and switching to a different oral anticoagulant (OAC) in patients with atrial fibrillation (AF) are unknown.

Objectives: To describe temporal patterns in first DOAC prescriptions, estimate the incidence, and identify predictors of switching to a different OAC within 1 year in OAC-naive AF patients.

Methods: In this retrospective cohort study, using a near-nationwide prescription registry (IQVIA, the Netherlands), we determined the number of patients per month initiated on each DOAC and identified predictors of switching within 1 year with robust Poisson regression.

Updates for newly diagnosed and recurrent glioblastoma: a review of recent clinical trials.

Purpose Of Review: Glioblastoma (GBM) is the most common and devastating primary malignant brain tumor. We summarize recent advances in radiotherapy, immunotherapy, and targeted therapy approaches for the treatment of newly diagnosed and recurrent glioblastoma. We also introduce ongoing clinical trials.

The change of epicardial adipose tissue characteristics and vulnerability for atrial fibrillation upon drastic weight loss.

Background: Obesity increases the risk of atrial fibrillation (AF). We hypothesize that 'obese' epicardial adipose tissue (EAT) is, regardless of comorbidities, associated with markers of AF vulnerability.

Methods: Patients >40y of age undergoing bariatric surgery and using <2 antihypertensive drugs and no insulin were prospectively included.

Design of the 18-year follow-up of the Danish COPSAC birth cohort.

Background: Atopic diseases, obesity and neuropsychiatric disorders are lifestyle-related and environmental-related chronic inflammatory disorders, and the incidences have increased in the last years.

Objective: To outline the design of the 18-year follow-up of the Copenhagen Prospective Study on Asthma in Childhood (COPSAC) birth cohort, where risk factors of atopic diseases, obesity and neuropsychiatric disorders are identified through extensive characterisation of the environment, along with deep clinical phenotyping and biosampling for omics profiling.

Methods: COPSAC is a Danish prospective clinical birth cohort study of 411 children born to mothers with asthma who were enrolled at 1 month of age and closely followed at the COPSAC clinical research unit through childhood for the development of atopic diseases.

Latent profile analysis of biopsychosocial measures in older patients with (un)explained persistent somatic symptoms.

Patients with persistent somatic symptoms (PSS) often receive either somatic or psychiatric care, depending on whether symptoms are respectively medically explained (MES) or unexplained (MUS). This separation may not be as clinically relevant as previously assumed; however, research on data-driven subgroups within cohorts of older patients with PSS is not available. Our goal is to identify more clinically relevant homogeneous subgroups beyond the distinction of MUS and MES among older patients with PSS by using a data-driven approach.

Anticoagulation in Patients With Device-Detected Atrial Fibrillation With and Without a Prior Stroke or Transient Ischemic Attack: The NOAH-AFNET 6 Trial.

Background: Short and rare episodes of atrial fibrillation (AF) are commonly detected using implanted devices (device-detected AF) in patients with prior stroke or transient ischemic attack (TIA). The effectiveness and safety of oral anticoagulation in patients with prior stroke or TIA and device-detected AF but with no ECG-documented AF is unclear.

Methods And Results: This prespecified analysis of the NOAH-AFNET 6 (Non-Vitamin K Antagonist Oral Anticoagulants in Patients With Atrial High Rate Episodes) trial with post hoc elements assessed the effect of oral anticoagulation in patients with device-detected AF with and without a prior stroke or TIA in the randomized, double-blind, double-dummy NOAH-AFNET 6 trial.

Production and characterization of novel Anti-HIV Fc-fusion proteins in plant-based systems: Nicotiana benthamiana & tobacco BY-2 cell suspension.

Multifunctional anti-HIV Fc-fusion proteins aim to tackle HIV efficiently through multiple modes of action. Although results have been promising, these recombinant proteins are hard to produce. This study explored the production and characterization of anti-HIV Fc-fusion proteins in plant-based systems, specifically Nicotiana benthamiana plants and tobacco BY-2 cell suspension.
