Filter by:Background：Gastric cancer is a globally important disease and the fifth most diagnosed malignant cancer in the world. Because it is usually diagnosed at an advanced stage, gastric cancer has a high mortality rate, making it the third most common cause of cancer-related death. Hot spots of gastric cancer incidence and mortality exist in East Asia, Eastern Europe and South America. It is still an urgent problem to find new diagnostic and prognostic markers and better understand the molecular mechanism of gastric cancer. Although radical resection and systemic chemotherapy have shown great improvement, the prognosis of gastric cancer (GC) patients is still depressing due to malignant proliferation and metastasis. Therefore, it is urgent to clarify the potential molecular mechanism of gastric cancer progression, which will contribute to the development of targeted therapy. Effective induction of tumor cell apoptosis is the most important feature of a new chemical agent for cancer treatment. There is increasing evidence that the cell cycle can act in concert with apoptosis to cause cell death under certain cellular stress conditions. A comprehensive understanding of the relationship between apoptosis and cell cycle is essential for developing effective cancer therapies. PWP1 is also known as endonuclein, which contains five WD40 repeated domains and belongs to the WD40-repeated superfamily. It is highly expressed in human pancreatic adenocarcinoma, where it functions as a cell-cycle regulator. However, the normal function of Pwp1 is largely unknown. Previous research data show that PWP1 plays a key role in regulating biological functions such as RNA processing, signal transduction, gene expression, vesicle transport, cytoskeleton assembly and cell cycle progression. Whether the high expression of PWP1 is ubiquitous in tumors, the relationship between the high expression and clinicopathological factors of tumors, and the mechanism of PWP1 in tumors are still unclear. Further exploration of the molecular mechanism of PWP1 in GC may provide new ideas and therapeutic targets for GC treatment in the future, and benefit clinical patients.
This study was conducted to investigate the relationship between diastolic notching on uterine artery Doppler and serum apelin-13 and 36 concentrations between 11 and 14 weeks of gestation.
Sedation during flexible bronchoscopy (FB) should maintain an adequate respiratory drive, ensure maximum comfort for the patient, and warrant that the objectives of the procedure are achieved. Nevertheless, the optimal sedation method for FB has yet to be established. This study aimed to compare the standard recommended combination of midazolam-fentanyl (MF) with that of dexmedetomidine-ketamine (DK) for patient sedation during FB. Patients subjected to FB were randomly assigned to a DK (n=25) and an MF group (n=25). The primary outcome was the rate of critical desaturation events (arterial oxygen saturation <80% with nasal oxygen supply 2 L/min). Secondary outcomes included sedation depth, hemodynamic complications, adverse events, and patient and bronchoscopist satisfaction.
This study will evaluate the effect of providing access to GPT-4, a large language model, compared to traditional diagnostic decision support tools on performance on case-based diagnostic reasoning tasks.
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.
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.
102 patients who have suspicious ALNs were included in our prospective study, which was approved by a tertiary health care facility ethics committee. Each suspicious lymph nodes (LNs) were examined with PDUS and SMI in terms of distribution, appearance and number of vascular structures and the still images were stored. Subsequently, imaging findings were re-evaluated after histopathological or follow-up results and were compared between benign and malign groups. In addition, we revealed the diagnostic perfomance of using the each possible combination of these features in PDUS and SMI. Finally, two radiologists with 22 years and 4 years of experience analyzed the images and interobserver agreement was assessed
To explore the potential efficacy of 18F-FAPI-04 PET/CT for PDAC tumour staging and compare the results with those obtained using 18F-FDG PET/CT.
For diagnosis of external and middle ear diseases, an otoscope is a key instrument to use. A microscope has been used as a reference standard to confirm pathology. An endoscope has been also widely used. Both microscope and endoscope provide an excellent image quality, can record and capture the images, and the images can be visualized with an export system. A digital otoscope is widely available and more affordable. A comparative study of the efficacy of the endoscope and the digital endoscope will be performed.
