AI Article Synopsis
- * Tumor-informed high sensitivity circulating tumor DNA (ctDNA) assays may help detect early disease, assess risk, and monitor treatment responses in advanced RCC, despite some concerns about their sensitivity.
- * Studies show ctDNA has high specificity (~100%) and can be a significant negative prognostic factor for disease progression, with ongoing development of novel assays to enhance detection in solid tumors like RCC.
Article Abstract
As therapeutics in renal cell carcinoma (RCC) continues to advance with approval of novel treatments and recently, adjuvant therapy, the need for highly sensitive tests that go beyond traditional methods to measure disease is becoming more crucial. Tumor informed high sensitivity circulating tumor DNA (ctDNA) assays originally developed for detection of minimal residual disease (MRD) theoretically could be utilized for initial detection of occult disease but also potentially for risk and response assessment in the management of advanced RCC. There are concerns related to the sensitivity of ctDNA based assays in RCC. This article aims to summarize the available evidence for high sensitivity MRD assays in RCC. We included studies with both localized and metastatic stages of RCC. The studies show a varying sensitivity depending on disease settings but a high specificity (∼100%) regardless. Detectable ctDNA appeared to be a significant negative prognostic risk factor for subsequent progressive disease. ctDNA may provide significant lead time allowing physicians to adapt therapy. Several high sensitivity assays with novel analytic approaches are in development for solid tumors including RCC.

Background: Oral squamous cell carcinoma (OSCC) is an aggressive malignancy with poor prognosis. Neutrophil infiltration has been associated with unfavorable outcomes in OSCC, but the underlying molecular mechanisms remain unclear.
Methods: This study integrated single-cell transcriptomics (scRNA-seq) with bulk RNA-seq data to analyze neutrophil infiltration patterns in OSCC and identify key gene modules using weighted gene co-expression network analysis (hdWGCNA).

Objective: Referring all women who tested positive for human papillomavirus (HPV) 16/18 to colposcopy may lead to potential over-referral issues. Triage tests based on cytology results face challenges in achieving accurate diagnoses. Our study aims to assess the clinical effectiveness of PAX1/JAM3 methylation (CISCER) test as a triage method for HPV 16/18-positive women.

Background: Sepsis is a life-threatening organ dysfunction with high morbidity and mortality. Various studies have demonstrated the effectiveness of Chinese tonic medicines (CTMs) in treating sepsis or septic shock. However, trials directly comparing the efficacy and safety of different CTMs for sepsis or septic shock are still lacking.

Strength-based video-feedback (SB-VF) is an attached base and culturally sensitive video-feedback intervention which promotes maternal well-being and sensitivity through using mentalization technics. The goals of this study were to investigate the feasibility, acceptability, and preliminary effectiveness of internet-delivered SB-VF to mother with post-partum depression during COVID-19 pandemic. A pilot randomized, two arm controlled trial was conducted (trial registration NCT04748731) with depressive symptoms' women (n = 172) from Chilean public primary health centers, 79 were randomized to either experimental group (on-line SB-VF plus treatment as usual [TAU], n = 41) or control group (TAU, n = 38).
