Background: COVID-19 is associated with intense systemic inflammation and abnormal coagulation profile leading to an increased incidence of pulmonary embolism (PE). This study investigates whether PE in COVID-19 patients has different clinical, laboratory and radiological characteristics when compared to traditional PE in COVID negative patients.
Methods: We conducted an observational, multicentric, cross-sectional study on consecutive patients diagnosed with PE at admission or during hospital stay from February 21 2019 to February 20 2021.

Objectives: To study the correlation between sarcopenia and hypertrophy of the future liver remnant(FLR) in patients undergoing portal vein embolization(PVE) before liver resection, and to assess the outcomes after resection.
Methods: This retrospective study examined patients underwent PVE from May 2012 to May 2023. Demographic, clinical and laboratory features were documented and total liver volumes(TLV) and FLR volumes were measured before and 2-4 weeks after PVE.
Evaluation of a context-aware chatbot using retrieval-augmented generation for answering clinical questions on medication-related osteonecrosis of the jaw.

The potential of large language models (LLMs) in medical applications is significant, and Retrieval-augmented generation (RAG) can address the weaknesses of these models in terms of data transparency and scientific accuracy by incorporating current scientific knowledge into responses. In this study, RAG and GPT-4 by OpenAI were applied to develop GuideGPT, a context aware chatbot integrated with a knowledge database from 449 scientific publications designed to provide answers on the prevention, diagnosis, and treatment of medication-related osteonecrosis of the jaw (MRONJ). A comparison was made with a generic LLM ("PureGPT") across 30 MRONJ-related questions.

Division of Vascular and Interventional Radiology, Mount Sinai Hospital.
Purpose: To investigate if Yttrium-90 radioembolization (Y90 TARE) is a safe and effective treatment in people living with HIV (PLWH) with hepatocellular carcinoma (HCC) across the BCLC stage spectrum.
Materials And Methods: A retrospective review was conducted of all patients with HCC presented at a multidisciplinary institutional liver tumor board who underwent Y90 TARE between January 2014 and June 2023. Thirty-nine patients with documented HIV seropositivity prior to Y90 TARE and adherence to HAART were included.
