Filter by:In the study, the investigators obtained gastric cancer tissues from 480 gastric cancer patients who had undergone surgery at the Zhejiang Cancer Hospital's biospecimen bank between 2012-2019, and obtained relevant clinical information. The gastric cancer tissues were subjected to transcriptomic, metabolomic and other multi-omics testing, and analyzed for the metabolic changes of gastric cancer, and proposed to discover relevant therapeutic targets.
Objective: the pre-hospital management of cancers is little known in General Medicine. The first lockdown related to the COVID-19 pandemic led to the closure of health facilities. Investigators were interested in the diagnosis and care pathway of digestive cancers in post-confinement in General Medicine in Nouvelle-Aquitaine.
Anomalous aortic origin of a coronary artery (AAOCA) is a group of rare congenital heart defects with various clinical presentations. The lifetime-risk of an individual living with AAOCA is unknown, and data from multicentre registries are urgently needed to adapt current recommendations and guide optimal patient management. The European Registry for AAOCA (EURO-AAOCA) aims to assess differences with regard to AAOCA management between centres.
In this study, we will prospectively recruit 100,000 individuals, including gastric cancer patients who have not undergone any anti-tumor treatment and non-gastric cancer participants. We will construct a diagnostic model for malignant tumors based on the combination of tongue imaging, tongue coating, saliva, and fecal multi-omics data (including metagenomics, proteomics, metabolomics, etc.). Additionally, it will explore the relationship between oral and intestinal microbiota and the development of malignant tumors.
This is an interventional with minimal risks and constraints (RIPH 2 in France), prospective, longitudinal, non-randomized, multicenter study. The present study will allow us to evaluate multiple factors assessing the Endotest® Diagnostic accuracy and its possible limitations. To characterize the Endotest® Diagnostic, the following parameters will be evaluated: - Repeatability: the verification of the invariability of its results without condition changes, - Circadian cycle: whether the circadian cycle affects the determination of the signature, - Intermediate fidelity: the verification of the invariability of its results with an operator change, - Interferences: the impact of different interferences on its results, - Stability: the possible modification of its results depending on the samples conditions of storage. The acts and procedures performed in this research will be divided into three visits: - Inclusion visit: performance of 4 Endotest® Diagnostics (3 at the visit and 1 at home) by the 60 included subjects, - "Circadian cycle" visit: performance of 17 Endotest® Diagnostics (14 at the visit and 3 post-visit at home) by 6 subjects selected after evaluation of the results of the inclusion visit, - "Repeatability-intermediate fidelity-interference-stability" visit: realization of 17 Endotest® Diagnostic by 10 or 16 subjects, depending on the results of the impact of the circadian cycle on the saliva signature. These subjects will be selected according to the results of the inclusion visit, excluding those who participated in the circadian cycle visit.
The aim of this study was to design a deep learning-based trained model to assist in HFimpEF diagnosis.
Tumors of the salivary glands occupy 0.5-1.2% of cases of head and neck tumors. They are primarily a surgical disease, as their treatment is basically the surgical excision. In this direction and in the context of the differential preoperative diagnosis, in addition to the imaging methods, the fine needle biopsy (FNA) was used, with which cell material is aspirated from the tumor and studied under the microscope. Although an increasing number of papers have been published in the international scientific literature over the last 5 years on the diagnostic accuracy of FNA in salivary glands, many of them are unable to quantify and omit to refer information that could affect the estimated diagnostic accuracy. Such information is for instance the clinical experience of the doctor who performs the FNA and of the one who assess the smear. The aim of this retrospective study is to evaluate the diagnostic accuracy of fine needle biopsy in adult patients with salivary gland tumor that underwent a surgical excision in two Oral and Maxillofacial Departments in Northern Greece. The present retrospective study was carried out from 2/2021 to 4/2022 by collecting data from the files of patients who underwent surgery at the Oral and Maxillofacial Clinic of the Theageneio Cancer Hospital of Thessaloniki 1996-2022 and the General Hospital of Thessaloniki G. Papanikolaou 2015-2022. The study was conducted according to the STARD 2015 protocol. FNA contributed significantly to the differential preoperative process in salivary gland diseases. The differential diagnosis of a lesion in benign / malignant preoperatively, with the use of FNA, enables the surgeon for a more beneficial to the patient and oncologically safer planning of the surgery. It is considered important the high sensitivity provided by the examination, as it helps to exclude with sufficient safety the possible malignancy of the tumor located in the salivary gland of the patient.
The goal of this observational study is to learn about antithrombotic regimens in Multiple myeloma patients. The main question it aims to answer is the efficacy of different types of thromboprophylaxis (antiplatelet agents, heparins, oral anticoagulants) in preventing venous thromboembolism (VTE).
The purpose of this study is to assess a new test to detect antibodies which may form following kidney transplant. These antibodies can be difficult to detect as they do not cause any symptoms but can lead to kidney damage. A new blood test will be performed alongside existing antibody tests to see how well the test functions in comparison and to see how well it is able to distinguish between inflammation caused by antibodies and other sorts of inflammation such as a urinary tract infection. The investigators also want to determine whether it is predictable whom will develop antibodies after a transplant and use these results to change the current way patients are monitored for antibodies after receiving a transplant. In addition to this, the investigators want to establish if patients over 60 years of age are relatively protected against immunological events such as rejection compared to patients who are under 60 years of age. The results could potentially lead to using a different immunosuppression regime based on which population age group patients belong to and lowering the risks associated with these drugs.
The increasing incidence of actinic keratosis (AK), morbus Bowen (MB) and cutaneous squamous cell carcinoma (cSCC), the patients with often multiple lesions and the disadvantages of invasive diagnostics show the need for an accurate non-invasive diagnostic tool for the determination of invasive growth in AK and MB. Optical coherence tomography (OCT) is a non-invasive scanner creating cross-sectional images of the skin, to a depth of 1-1,5 mm based on light waves. Until now, OCT has been proposed as non-invasive diagnostic tool for basal cell carcinomas. Although the diagnostic value of OCT for detection and sub-typing of basal cell carcinomas has already been demonstrated, it is unclear whether OCT can discriminate between invasive and non-invasive lesions (AK, MB and cSCCs). There are some studies that describe OCT characteristics of AK, MB and cSCCs, however, these characteristics have a lot of overlap (8-13). To date there are no clearly distinctive OCT features to distinguish between AK, MB and cSCCs. This study aims to investigate the value of OCT in discriminating between the presence and absence of invasion in lesions with clinical suspicion for invasion. Two experienced OCT-assessors will evaluate the OCT scans independently. The OCT assessors are blinded to the histological diagnosis of the lesions (invasive or non-invasive), which is used as golden standard. A 5-point Likert scale is used for OCT assessment. 1. Definitely not invasive 2. Probably not invasive 3. Unknown, probably invasive/probably not invasive 4. Probably invasive 5. Definitely invasive In addition to completing the Likert-scale, assessors are asked to describe the presence/absence of predefined OCT characteristics (a.o. hyperkeratosis and the presence of the dermo-epidermal junction) In case of disagreement between the independent assessors, the OCT scan will be re-assessed in a consensus meeting.
