Credit card usage has surged, heightening concerns about fraud. To address this, advanced credit card fraud detection (CCFD) technology employs machine learning algorithms to analyze transaction behavior. Credit card data's complexity and imbalance can cause overfitting in conventional models.

Objective: Timely, accurate distinction between behavioural variant frontotemporal dementia (bvFTD) and primary psychiatric disorders (PPD) is a clinical challenge. Blood biomarkers such as neurofilament light chain (NfL) and glial fibrillary acidic protein (GFAP) have shown promise. Prior work has shown NfL helps distinguish FTD from PPD.

Oral squamous cell carcinoma (OSCC) is known to be driven by multiple intricated receptor tyrosine kinases (RTKs) including EGFR, PI3K/AKT and MAPK signaling pathways. However, whilst targeting EGFR with cetuximab has been approved for the treatment of OSCC, other single-agent inhibitors of the RTKs have shown modest effects in improving survival. From the genome-wide CRISPR/Cas9 screen on 21 OSCC cell lines, we have identified among the top essential genes in OSCC.

Article Synopsis
  • - The study aimed to evaluate the use of a seizure recurrence prediction tool in a First Seizure Clinic by analyzing the accuracy of initial diagnoses and the effectiveness of computational models in predicting seizures after a first unprovoked seizure (FUS).
  • - Among the 487 patients in the accuracy cohort, 69% maintained their initial diagnosis over 6 months, but misdiagnosis occurred in 5%, with 17% progressing to epilepsy; in the prediction cohort of 181 patients, the 12-month seizure recurrence rate was found to be 41%.
  • - While the initial diagnosis showed high accuracy, the current prediction models' performance was modest, suggesting that additional data beyond just clinical factors is necessary to enhance the ability to

Objective: Telehealth paradigms are essential for remotely managing patients with chronic conditions. To assist clinicians in handling the large volumes of data collected through these systems, clinical decision support systems (CDSSs) have been developed. However, the effectiveness of CDSSs depends on the quality of remotely recorded physiological data and the reliability of the algorithms used for processing this data.
