Robot-assisted versus manually guided stereotactic biopsy for intracranial lesions - a systematic review and meta-analysis.

Stereotactic biopsies are essential for obtaining accurate histopathological analysis to guide treatment decisions for deep-seated brain lesions. Manually guided methods, while commonly used and highly precise, can be limited by potential inaccuracies and insufficient tissue sampling. The emerging robot-assisted (RA) techniques offer enhanced precision and could address these limitations for improved accuracy.

Molecular Insights Into Actinic Cheilitis and Lower Lip Squamous Cell Carcinoma: AURKA and AURKB Amplifications and Their Association With Tumor Microenvironment.

Background: Lip exposure to carcinogens lead to several disorders, such as actinic cheilitis (AC) and lower lip squamous cell carcinoma (LLSCC). Although several studies have described important pathways in lip carcinogenesis, the comprehension of association of target genes in this process and their association with tumor microenvironment still need to be better understood.

Methods: Tissue samples of 30 AC and 17 LLSCC cases were included for histopathological analysis, immunohistochemical expression of CD4, CD8, and PD-L1, and fluorescence in situ hybridization for AURKA, AURKB, TP53, PTEN, CCND1, and MYC.

Association of Cytotoxic T-Lymphocyte Antigen-4 () Genetic Variants with Risk and Outcome of Cutaneous Melanoma.

This study aimed to verify whether germline single nucleotide variants (SNV) in gene, c.-1765C>T, c.-1661A>G, c.

Urinary Diversion Can Improve the Chance of Implementing New Therapeutic Lines in Patients with Malignant Ureteral Obstruction: A Multicenter Study.

Purpose: Malignant ureteral obstruction is generally associated with a poor disease prognosis; therefore, managing these cases is challenging. We describe our experience in treating malignant ureteral obstruction with urinary diversion and the impact of these procedures on the indication for new antineoplastic therapy and survival.

Materials And Methods: We retrospectively reviewed the data of patients with advanced cancer associated with malignant ureteral obstruction who underwent urinary diversion at three tertiary institutions between January 2013 and July 2022.

BDNF methylation associated with stress in women: Novel insights in epigenetics and inflammation.

The brain-derived neurotrophic factor (BDNF) gene plays an important role in modulating the stress-response axis and inflammation, which can be regulated by epigenetic mechanisms. BNDF methylation has been associated with stress-related psychiatric disorders such as depression, anxiety and post-traumatic stress. Previous studies have reported that stressful events are involved with long-lasting alterations in DNA methylation (DNAm) of the BNDF exon IV promoter, suggesting that glucocorticoids and inflammatory cytokines can regulate this process.

Exploring patient awareness of palliative care - optimal timing and preferred approaches.

Objectives: To explore patients' awareness levels of palliative care (PC) and how this awareness shapes their preferences regarding the timing and approach for discussing it.

Methods: The study, conducted at a prominent institution specializing in oncology care, enrolled women aged 18-75 years who had been diagnosed with breast cancer. Patients completed guiding questions: Do you know what PC is?, When is the most appropriate time and the most appropriate way to discuss PC?.

The Cancer-Specific Health Economic Measure QLU-C10D is Valid and Responsive for Assessing Health Utility in Patients with Thyroid Cancer.

Health economic appraisals often rely on the assessment of health utilities using preference-based measures (PBM). The cancer-specific PBM, European Organisation for Research and Treatment of Cancer Quality of Life Utility - Core 10 Dimensions (EORTC QLU-C10D), was developed recently, and now needs to be validated in various clinical populations. In a multicenter, multinational prospective cohort study, we longitudinally collected EORTC QLQ-C30 and EQ-5D-5L data from patients with thyroid cancer.

Association of Fusobacterium nucleatum Levels by ddPCR in Oral Rinse Samples With Periodontal Disease in Oral Squamous Cell Carcinoma Patients and in Controls.

Background: The role of microbiome, particularly Fusobacterium nucleatum (Fn), in periodontal disease and oral squamous cell carcinoma (OSCC) has been recently explored. This study aimed to evaluate the Fn presence and its levels in oral rinse samples from Brazilian OSCC patients and healthy individuals and its association with sociodemographic, clinical, and oral health features.

Methods: In this case-control study, 80 participants were included, 31 OSCC patients and 49 individuals without a cancer history.

Development of Leadership Skills in Medical Education: Protocol for a Scoping Review.

Background: Leadership is recognized as an essential competency in health care and science, being central for professionals to face health challenges. Few physicians feel prepared to serve as leaders in the health care environment, and few receive training in the leadership skills needed to be successful. Teaching leadership skills together with extensive, longitudinal, clinical education in an authentic and nurturing environment can effectively develop students for leadership in medicine.

The Application of Large Language Models in Gastroenterology: A Review of the Literature.

Large language models (LLMs) are transforming the medical landscape by enhancing access to information, diagnostics, treatment customization, and medical education, especially in areas like Gastroenterology. LLMs utilize extensive medical data to improve decision-making, leading to better patient outcomes and personalized medicine. These models are instrumental in interpreting medical literature and synthesizing patient data, facilitating real-time knowledge for physicians and supporting educational pursuits in medicine.

Feasibility of an environmental scan-based approach to collecting information about factors impacting cancer genetics services in Latin American countries.

Objective: Clinical cancer genetics services are expanding globally, but national policy and health care systems influence availability and implementation. Understanding the environmental factors within a country is required to appropriately implement, adapt, and evaluate cancer genetics service delivery models. An environmental scan (ES) is an approach used in business, public health, health care and other sectors to collect information about an environment or system for strategic decision making and program planning.

Interleukin-12 treatment reduces tumor growth and modulates the expression of CASKA and MIR-203 in athymic mice bearing tumors induced by the HGC-27 gastric cancer cell line.

Gastric cancer (GC) is one of the most common malignant tumors in the digestive system and due to its poor prognosis, there is an increase in the demand for more effective anticancer therapies. Interleukins are potential anticancer agents which can modulate expression of cancer related genes and have therapeutic effects. Interleukin 12 (IL-12) exhibits potent anti-tumor, anti-angiogenic and anti-metastatic activities and represents the ideal candidate for tumor immunotherapy, due to its ability to activate both innate and adaptive immunities.

Cisplatin‑resistant germ cell tumor models: An exploration of the epithelial‑mesenchymal transition regulator .

Germ cell tumors (GCTs) constitute diverse neoplasms arising in the gonads or extragonadal locations. Testicular GCTs (TGCTs) are the predominant solid tumors in adolescents and young men. Despite cisplatin serving as the primary therapeutic intervention for TGCTs, 10‑20% of patients with advanced disease demonstrate resistance to cisplatin‑based chemotherapy, and epithelial‑mesenchymal transition (EMT) is a potential contributor to this resistance.

Impact of Preoperative Counseling and Education on Decreasing Anxiety in Patients With Gynecologic Tumors: A Randomized Clinical Trial.

Objective: To evaluate the impact of counseling and preoperative education on reducing anxiety in patients undergoing surgery for gynecologic cancer.

Methods: In this randomized clinical trial, patients with gynecological tumors undergoing surgical treatment between 15 and 60 days preoperatively, were included. The group was randomized to receive preoperative routine orientation plus preoperative counseling and education by nursing (experimental group [EG]) or receive preoperative routine orientation only (control group [CG]).
