Article Abstract

Clot waveform analysis (CWA) involves an analysis of the activated partial thromboplastin time (CWA-APTT), diluted prothrombin time (CWA-dPT), and small amount of thrombin time (CWA-sTT), and clot fibrinolysis waveform analysis (CFWA). CWA was evaluated in order to propose its clinical application. CWA exhibits an abnormal waveform, as well as peak times and heights in its derivative curves. Although the CWA-APTT is frequently examined and useful for diagnosing clotting deficiency, it has several limitations. Therefore, modified CWAs have been proposed for clinical application. WA-dPT (small amount of tissue factor-induced FIX activation; sTF/FIXa) can detect hypercoagulability. WA-sTT reflects thrombin burst and evaluates hemostatic abnormalities in patients treated with emicizumab. FWA is a variant of WA-APTT that includes a small amount of tissue-type plasminogen activator, indicating both clotting and fibrinolysis. The CWA-APTT and modified CWA should be further investigated in various diseases for many applications in the clinical setting, including the monitoring of hemophilia patients and patients receiving anticoagulant therapy and the differential diagnosis of diseases.

Objective: To develop, implement, and evaluate a novel process used for residency application review that deemphasizes metrics known to create bias with the goal of interviewing and matching a more diverse resident cohort.

Methods: Between 2020 and 2023, a novel standardized rubric and application review process were developed and implemented at the authors' academic training program. The rubric deemphasized USMLE scores, honor society membership, and number of publications while utilizing an AI-driven pre-sort of applications, facilitating holistic review.

The rapid increase in multidrug-resistant (MDR) bacteria and biofilm-associated infections has intensified the global need for innovative antimicrobial strategies. Phage therapy offers promising precision against MDR pathogens by utilizing the natural ability of phages to specifically infect and lyse bacteria. However, their clinical application is hampered by challenges such as narrow host range, immune clearance and limited efficacy within biofilms.

Oral cancer is a major global health burden, ranking sixth in prevalence, with oral squamous cell carcinoma (OSCC) being the most common type. Importantly, OSCC is often diagnosed at late stages, underscoring the need for innovative methods for early detection. The oral microbiome, an active microbial community within the oral cavity, holds promise as a biomarker for the prediction and progression of cancer.

The current review article deals with the evaluation of the oncocytic/oncocytoid lesions in the salivary gland. The authors will focus on the diagnosis of Warthin tumor (WT) as a launching point to detail important morphologic findings that should prompt designation of an aspirate as oncocytic salivary gland neoplasm of uncertain malignant potential or other Milan categories. Oncocytic cells are defined as cells with a moderate to abundant amount of eosinophilic finely granular cytoplasm, round-to-oval nuclei, and large-distinct nucleoli.
