The purpose of this study is to collect blood samples from a large number of individuals with cancer to create a database for researchers to use in future studies. Researchers may use this database to discover new ways to detect and treat cancer and other diseases. Future studies may use stored blood samples to discover how genes affect health and disease.
Nasopharyngeal carcinoma is one of the most common malignant tumors in China, with the progress of radiochemical comprehensive treatment, early stage The 5-year survival rate of nasopharyngeal cancer is more than 95%. However, due to the hidden site of nasopharyngeal carcinoma and the lack of obvious early clinical symptoms, more than 70% of the 87,000 newly diagnosed cases each year belong to the advanced stage of nasopharyngeal carcinoma, and the 5-year survival rate of advanced nasopharyngeal carcinoma is only about 70%. Therefore, early screening and diagnosis and early treatment are the key to improve the survival of patients with nasopharyngeal cancer. Selecting a sensitive and accurate biomarker for nasopharyngeal cancer and relying on a simple and feasible examination method for sampling detection will greatly improve the early diagnosis rate of nasopharyngeal cancer. DNA methylation is a form of chemical modification of DNA that can be done without altering the DNA sequence changes in genetic expression. The main role of DNA methylation is to regulate gene expression. Tumor suppressor genes play the functions of regulating cell differentiation, maturation and programmed death. However, if methylation of promoter region occurs, the expression of tumor suppressor genes is inhibited and the function is lost, resulting in cells remaining in the stage of low differentiation and proliferation, inhibition of apoptosis, formation of blood vessels by cluster cells, loss of cell adhesion, and formation of tumors. It can be seen that DNA methylation occurs in the early stage of tumor, and this biological feature makes it a strong application prospect in early tumor screening. There are many methods to detect DNA Methylation, among which methylation-specific PCR (MSP) can easily and quickly determine the methylation status of a specific gene, meeting the affordable, convenient, and easy to generalize characteristics required for screening tests. In combination with previous MSP experiments and previous reports, we found that the methylation levels of promoter fragments of H4C6, Septin9 and RASSF1A genes in nasopharyngeal carcinoma tissues were significantly higher than those in healthy human nasopharyngeal tissues. This suggests that methylation of these three genes may be used as biomarkers for early screening and diagnosis of nasopharyngeal carcinoma. Therefore, this study intends to detect the methylation status of H4C6, Septin9 and RASSF1A genes based on MSP method with simple operation and low cost. Using clinicopathological diagnosis as the gold standard, the value of this gene methylation index in early screening and early diagnosis of nasopharyngeal cancer was verified, providing a new detection index and method for improving the early diagnosis rate of nasopharyngeal cancer.
The investigator aims to conduct an open pilot study (N=12; 10 completers) to test the feasibility, acceptability, and credibility of an asynchronous web-based mind-body intervention (Toolkit for Resilient Life beyond Pain and Substance Use; Web-TIRELESS) for adult patients with a comorbidity of non-traumatic painful upper-extremity condition(s) (NPUC) and risky substance use. Deliverables: 1) Adapt and refine open pilot protocol, patient recruitment, and other study materials. 2) Assess the feasibility, acceptability, and credibility of Web- TIRELESS in preparation for a future feasibility RCT. Participants will complete 4 on-demand video sessions at their own pace (approximate pace of 1 session per week) and complete baseline and post-test assessments. participants may also partake in an exit interview to provide feedback on Web-TIRELESS to further refine the program and study protocol for future iterations.
to evaluate the ability of the Optical genome Mapping (OGM) approach to detect simple and complex constitutional chromosomal aberrations of clinical relevance, which had previously been identified with standard diagnostic approaches (karyotyping, FISH, CNV-microarray) in the context of neurodevelopmental disorders (NDDs) with/wo congenital anomalies (CA)
Non-small cell lung cancer (NSCLC), occupying a disquieting position as the second most prevalent and deadliest neoplasm worldwide, afflicts an estimated 30% of its patients with intracranial metastatic spread. Among these, leptomeningeal metastasis (LM) is an exceptionally surreptitious and perilous manifestation, often evading timely and accurate diagnosis. The clinical landscape is further complicated by the presence of patients who, due to various reasons, are unable to undergo lumbar puncture, a procedure crucial for the investigation of LM. Moreover, even when cerebrospinal fluid (CSF) analysis via conventional cytological and immunohistochemical methods is attempted, a definitive diagnosis of LM may remain elusive in a subset of cases. Intrathecal chemotherapy, particularly via the administration of pemetrexed, which has demonstrated both notable efficacy and an acceptable safety profile when delivered directly into the cerebrospinal space, constitutes a cornerstone of treatment for NSCLC-LM. Despite its importance, the lack of robust, validated biomarkers to gauge the therapeutic response to such interventions represents a significant knowledge gap. This deficit is compounded by the inherent challenges associated with CSF samples, including their limited availability and the suboptimal sensitivity and high resource demands of current ctDNA assessment techniques. To address these pressing diagnostic and monitoring needs in NSCLC-LM management, the investigator proposes a forward-looking, non-interventional clinical study harnessing the power of cutting-edge proteomic technologies. These platforms, characterized by their high throughput, exquisite sensitivity, and minimal sample volume requirements, offer a promising avenue for elucidating the intricacies of chemotherapy response in intrathecal therapy. The study aims to provide valuable insights into improving diagnostic accuracy for LM in NSCLC patients and to establish a more rigorous framework for assessing treatment efficacy in individuals undergoing intrathecal chemotherapy, ultimately contributing to enhanced patient care and personalized therapeutic strategies.
The goal of this prospective, case-control study is to discover the specific "omics" biomarkers of early stage of lung cancer using the non-invasive samples (breath, urine and serum) in a total of 200 subjects (100 healthy controls and 100 lung cancer patient). The main questions it aims to answer are: - Which are the "omics" biomarkers that characterize the early stage of lung cancer? - How to Translate Laboratory Data into Clinical Data? For each participant we will collected the breath, urine and blood samples. In lung cancer patients group the samples will be sample before lung cancer resection. The samples of Breath, urine and serum will be analysed using different type of analysis: eNose and the Gas Chromatography combined with Ion Mass Spectrometry (GC/IMS). Moreover, Serum will be analyzed by mass-spectrometry-based proteomics. The purpose of these analyses will be to find biomarkers capable of distinguishing the early-stage of lung cancer from the healthy group. Followup will be performed to evaluate the possible change of the volatolomic and proteomic profile.
An Open, Dose-escalation, Phase 1b Clinical Trial to Evaluate the Safety and Efficacy of EN001 in Patients with Charcot-Marie-Tooth Disease type 1A (CMT1A)
Dual diagnosis refers to patients with both severe mental illness and substance abuse. Dual diagnosis is therefore a challenging condition to treat, and the group typically represents the most vulnerable individuals in society. Historically, research on dual diagnosis has been underprioritized, and thus, we still do not know enough about how to best assist this vulnerable group. However, new studies indicate that virtual reality programs can reduce anxiety in patients with psychotic disorders. They achieve this by providing access to a virtual therapist and lifelike environments where patients can challenge their thoughts about the dangers of navigating the world. For both psychotic disorders and substance abuse, we know that anxiety often plays a role in the clinical picture. Therefore, anxiety almost always has an impact on dual diagnosis patients, where it is crucial in maintaining substance abuse and functional impairment. Despite this, anxiety is rarely a focus in existing treatment options, as it is too resource-intensive in addition to an already intensive treatment process. This study investigates whether the resource barrier can be overcome and whether hospitalized dual diagnosis patients can experience reduced anxiety, fewer relapses, and better outcomes after discharge when their anxiety is treated through partially automated virtual reality therapy.
The aim of this randomised clinical trial is to evaluate the short and longterm effects of a transdiagnostic mentalization-based intervention (Lighthouse MBT Parenting Program) compared to care as usal (CAU) for parents with a mental disorder in adult mental health service.
