Longitudinal profiles of oral microbiome in patients with nasopharyngeal carcinoma and their prognostic implications.

Background: Oral microbiome has been associated with various cancers, including nasopharyngeal carcinoma (NPC), but its role in cancer treatment and prognosis remains largely unknown. This study aims to address the dynamic changes in oral microbiome following cancer treatment and their prognostic implications in NPC patients.

Patients And Methods: Unstimulated whole saliva samples were collected from 23 NPC patients before and after treatment, with an average of 2.

Feasibility and acceptability of a culturally adapted psychological first aid training intervention (Preparing Me) to support the mental health and well-being of front-line healthcare workers in China: a feasibility randomized controlled trial.

Psychological first aid (PFA) training helps to prepare healthcare workers (HCWs) to manage trauma and stress during healthcare emergencies, yet evidence regarding its effectiveness and implementation is lacking. A two-arm feasibility randomized controlled trial design was conducted in a Chinese tertiary hospital. Participants were randomly allocated to receive either a culturally adapted PFA training (the intervention arm) or psychoeducation (the control arm).

The interaction and mediation effects between the host genetic factors and Epstein-Barr virus VCA-IgA in the risk of nasopharyngeal carcinoma.

Previous studies have demonstrated strong associations between host genetic factors and Epstein-Barr virus (EBV) VCA-IgA with the risk of nasopharyngeal carcinoma (NPC). However, the specific interplay between host genetics and EBV VCA-IgA on NPC risk is not well understood. In this two-stage case-control study (N = 4804), we utilized interaction and mediation analysis to investigate the interplay between host genetics (genome-wide association study-derived polygenic risk score [PRS]) and EBV VCA-IgA antibody level in the NPC risk.

The mediating role of coping styles in the relationship between second victim experience and professional quality of life among nurses: a cross-sectional study.

Background: Studies have shown that second-victim experiences could increase risks of the compassion fatigue while support from individuals and organisations is most often protection. However, the risk for poor compassion satisfaction and increased compassion fatigue in nurses aroused by adverse events remains an underestimated problem, meanwhile, litter known about the role of positive and negative coping styles among nurses suffering from adverse events. This study aims to investigate the effect of second-victim experiences on the professional quality of life among nurses and to determine the mediating role of coping styles in the relationship between second-victim experiences and professional quality of life.

CRISPR Cas12a-mediated amplification-free digital DNA assay improves the diagnosis and surveillance of Nasopharyngeal carcinoma.

Sensitive and accurate cell-free plasma Epstein-Barr virus (EBV) DNA measurement is essential in the routine diagnosis, monitoring and treatment of Nasopharyngeal Carcinoma (NPC). This measurement in commercial and in-house assay are commonly based on real-time quantitative PCR (qPCR) method, which requires reference materials for standardization and lack quantitative precision due to amplification bias or cross-contamination. To address these issues, we developed a CRISPR/Cas12a-mediated amplification-free digital DNA assay, which targets the repetitive sequences of EBV DNA and utilizes the cis-cleavage activity of CRISPR-Cas12a prior to droplet generation.

Saliva biopsy: Detecting the difference of EBV DNA methylation in the diagnosis of nasopharyngeal carcinoma.

Saliva sampling is a non-invasive method, and could be performed by donors themselves. However, there are few studies reporting biomarkers in saliva in the diagnosis of NPC. A total of 987 salivary samples were used in this study.

Quantitative detection of Epstein-Barr virus DNA methylation in the diagnosis of nasopharyngeal carcinoma by blind brush sampling.

Detecting EBV DNA load in nasopharyngeal (NP) brushing samples for the diagnosis of nasopharyngeal carcinoma (NPC) has attracted widespread attentions. Currently, NP brush sampling mostly relies on endoscopic guidance, and there are few reports on diagnostic markers suitable for nonguided conditions (blind brush sampling), which is of great significance for extending its application. One hundred seventy nasopharyngeal brushing samples were taken from 98 NPC patients and 72 non-NPC controls under the guidance of endoscope, and 305 blind brushing samples were taken without endoscopic guidance from 164 NPC patients and 141 non-NPC controls (divided into discovery and validation sets).

A polygenic risk score for nasopharyngeal carcinoma shows potential for risk stratification and personalized screening.

Polygenic risk scores (PRS) have the potential to identify individuals at risk of diseases, optimizing treatment, and predicting survival outcomes. Here, we construct and validate a genome-wide association study (GWAS) derived PRS for nasopharyngeal carcinoma (NPC), using a multi-center study of six populations (6 059 NPC cases and 7 582 controls), and evaluate its utility in a nested case-control study. We show that the PRS enables effective identification of NPC high-risk individuals (AUC = 0.

Banking of Tumor Tissues: Effect of Preanalytical Variables in the Phase of Pre- and Postacquisition on RNA Integrity.

RNA integrity of tumor tissues from 12 common organs was measured, and tumor tissues from liver were found to have the best RNA integrity in our previous study. The effects of preanalytical variables in the phase of pre- and postacquisition on RNA integrity were further assessed in hepatocellular carcinoma (HCC) tissues in this study. RNA integrity number (RIN) was measured in tissues from 146 HCC patients.
