A Research Protocol for a Phase II Single-Arm Clinical Trial Assessing the Feasibility and Efficacy of Neoadjuvant Anastrozole in Patients With Luminal Breast Cancer and Low Proliferative Index: The ANNE Trial.

Introduction: Neoadjuvant endocrine therapy (NET) is recommended for the treatment of invasive breast cancer (BC), particularly luminal subtypes, in locally advanced stages. Previous randomized studies have demonstrated the benefits of aromatase inhibitors in this context. However, NET is typically reserved for elderly or frail patients who may not tolerate neoadjuvant chemotherapy.

Ophthalmic rehabilitation in oncology care.

Ophthalmic rehabilitation refers to the multidisciplinary approach to restoring, maximizing, and preserving the visual function and quality of life for patients affected by ocular manifestations of cancer or its treatments. Besides its approach to low vision, ophthalmic rehabilitation also encompasses a series of reconstructive interventions to mitigate anatomic deficits that may interplay with visual impairment. A gamut of oncologic conditions may result in ocular disabilities, including primary intraocular tumours, secondary metastases, or adverse effects of systemic therapies such as chemotherapy, radiation, and surgery.

Innovative solutions? Belzutifan therapy for hemangioblastomas in Von Hippel-Lindau disease: A systematic review and single-arm meta-analysis.

Background: Von Hippel-Lindau (VHL) disease is a rare autosomal dominant disorder that predisposes patients to develop multiple cysts and tumors, such as hemangioblastomas (HBs) and clear cell renal cell carcinoma (ccRCC), due to mutations in the VHL tumor suppressor gene. While treatment of HBs varies based on their characteristics and has improved patient survival, it still involves high morbidity and mortality, leading to ongoing debates and studies to refine therapy strategies. Recent developments include the emergence of Belzutifan, a novel inhibitor targeting hypoxia-inducible factor 2α (HIF-2α), which has shown promising results in ongoing trials, particularly for patients not immediately requiring surgery.

EV-miRNAs from breast cancer patients of plasma as potential prognostic biomarkers of disease recurrence.

Background: Extracellular vesicles (EVs), ubiquitously released by blood cells, facilitate intercellular communication. In cancer, tumor-derived EVs profoundly affect the microenvironment, promoting tumor progression and raising the risk of recurrence. These EVs contain miRNAs (EV-miRNAs), promising cancer biomarkers.

Inflammatory breast cancer microenvironment repertoire based on DNA methylation data deconvolution reveals actionable targets to enhance the treatment efficacy.

Background: Although the clinical signs of inflammatory breast cancer (IBC) resemble acute inflammation, the role played by infiltrating immune and stromal cells in this aggressive disease is uncharted. The tumor microenvironment (TME) presents molecular alterations, such as epimutations, prior to morphological abnormalities. These changes affect the distribution and the intricate communication between the TME components related to cancer prognosis and therapy response.

Comparative efficacy and safety of sodium fluorescein-guided surgery versus standard white light for resection of brain metastases: a systematic review and meta-analysis.

Purpose: Recent studies have investigated if the sodium fluorescein-guided (SFg) improves the extent of resection of BMs when compared to standard white light (sWL). Therefore, we aimed to assess the comparative efficacy and safety of SFg and sWL for resection of BMs.

Methods: We searched Medline, Embase, and Cochrane Library databases following Cochrane and PRISMA guidelines for studies reporting comparative data of SFg and WL resection of BMs.

Functional evaluation of germline TP53 variants identified in Brazilian families at-risk for Li-Fraumeni syndrome.

Germline TP53 pathogenic variants can lead to a cancer susceptibility syndrome known as Li-Fraumeni (LFS). Variants affecting its activity can drive tumorigenesis altering p53 pathways and their identification is crucial for assessing individual risk. This study explored the functional impact of TP53 missense variants on its transcription factor activity.

Vedolizumab versus ustekinumab in Crohn's disease with prior anti-tumor necrosis factor failure: an updated meta-analysis.

Ustekinumab and vedolizumab are key treatment options for Crohn's disease patients who fail anti-tumor necrosis factor (TNF) therapy. This updated meta-analysis aims to compare the efficacy and safety of these two drugs. We performed a systematic review in PubMed, Embase , and Cochrane databases searching for randomized and nonrandomized studies comparing vedolizumab versus ustekinumab in patients with Crohn's disease with previous anti-TNF failure or intolerance.

DNA methylation profile of inflammatory breast cancer and its impact on prognosis and outcome.

Background: Inflammatory breast cancer (IBC) is a rare disease characterized by rapid progression, early metastasis, and a high mortality rate.

Methods: Genome-wide DNA methylation analysis (EPIC BeadChip platform, Illumina) and somatic gene variants (105 cancer-related genes) were performed in 24 IBCs selected from a cohort of 140 cases.

Results: We identified 46,908 DMPs (differentially methylated positions) (66% hypomethylated); CpG islands were predominantly hypermethylated (39.

Enhancing Colorectal Cancer Screening with Droplet Digital PCR Analysis of Fusobacterium nucleatum in Fecal Immunochemical Test Samples.

Fecal immunochemical test (FIT) followed by colonoscopy in positive cases is commonly used for population-based colorectal cancer screening. However, specificity of FIT for colorectal cancer is not ideal and has poor performance for advanced adenoma detection. Fecal Fusobacterium nucleatum (Fn) detection has been proposed as a potential noninvasive biomarker for colorectal cancer and advanced adenoma detection.

Same-day discharge in craniotomy: A systematic review and meta-analysis.

Background: Traditionally, patients undergoing craniotomy were subject to extended hospital stays for intensive monitoring and management of potential complications. However, with the evolution of surgical methods, anesthesia, and postoperative protocols, the feasibility and interest in same-day discharge (SDD) are growing. This study aimed to evaluate whether same-day discharge is a safe and feasible approach in craniotomy through a meta-analysis of the available literature.

Determination of pesticide residues in urine by chromatography-mass spectrometry: methods and applications.

Introduction: Pollution has emerged as a significant threat to humanity, necessitating a thorough evaluation of its impacts. As a result, various methods for human biomonitoring have been proposed as vital tools for assessing, managing, and mitigating exposure risks. Among these methods, urine stands out as the most commonly analyzed biological sample and the primary matrix for biomonitoring studies.

Pharmacologic Management of End-of-Life Delirium: Translating Evidence into Practice.

End-of-life delirium affects a vast majority of patients before death. It is highly distressing and often associated with restlessness or agitation. Unlike delirium in other settings, it is considered irreversible, and non-pharmacologic measures may be less feasible.

Enhancing scaffold-free spheroid models: 3D cell bioprinting method for metastatic HSC3-Oral squamous carcinoma cell line.

3D in vitro systems offer advantages over the shortcomings of two-dimensional models by simulating the morphological and functional features of in vivo-like environments, such as cell-cell and cell-extracellular matrix interactions, as well as the co-culture of different cell types. Nevertheless, these systems present technical challenges that limit their potential in cancer research requiring cell line- and culture-dependent standardization. This protocol details the use of a magnetic 3D bioprinting method and other associated techniques (cytotoxicity assay and histological analysis) using oral squamous cell carcinoma cell line, HSC3, which offer advantages compared to existing widely used approaches.
