Background: Generative pre-trained transformer-4 (GPT-4) is a large language model (LLM) trained on a vast corpus of data, including the medical literature. Nutrition plays an important role in managing inflammatory bowel disease (IBD), with an unmet need for nutrition-related patient education resources. This study examines the accuracy, comprehensiveness, and reproducibility of responses by GPT-4 to patient nutrition questions related to IBD.

Article Synopsis
- The study analyzes national data on gastrointestinal bleeding (GIB) mortality in the U.S. from 2010 to May 2023, highlighting trends and identifying vulnerable populations.
- Despite a consistent decrease in GIB deaths from 2010 to 2019, there was a surge in excess mortality during the COVID-19 pandemic, especially among young males aged 19-44.
- By 2023, GIB-related mortality rates returned to expected levels, indicating a resolution of pandemic-related excess deaths.
Background: Radiofrequency Ablation (RFA) and Microwave Ablation (MWA) are alternative treatments for colorectal liver metastasis (CRLM) patients that are unsuitable for resection. However, consensus is lacking regarding selection criteria, tumour characteristics, ablation technique delivery, and device settings. This study aims to summarise current evidence to inform future prospective studies.

Methods: We designed and developed a retractor-camera combination for minimally invasive heart surgery; the cable and camera were connected to the underbelly of the left atrial retractor blade to provide an illuminated, wide-angle view of the mitral valve. We conducted ex vivo, in vivo, and, ultimately, a first-in-man randomized, nonanonymized clinical trial on 20 patients who required minimally invasive mitral valve surgery.
Most recent studies on the coronavirus disease 2019 (COVID-19) pandemic and cutaneous melanoma (CM) focused more on delayed diagnosis or advanced presentation. We aimed to ascertain mortality trends of CM between 2012 and 2022, focusing on the effects of the COVID-19 pandemic. In this serial population-based study, the National Vital Statistics System dataset was queried for mortality data.

- Cirrhosis is increasingly common in Arab countries and requires complex care; this study evaluates the accuracy of ChatGPT in answering cirrhosis-related questions in both Arabic and English.
- ChatGPT's responses were assessed by a hepatologist, revealing that 72.5% of Arabic responses were correct, but only 24.2% were comprehensive, indicating room for improvement.
- Compared to English responses, Arabic responses were generally less accurate, with the model producing completely incorrect answers to 13.2% of questions; thus, it should be considered a supplemental resource rather than a substitute for professional medical advice.
Purpose: ChatGPT is a large language model trained on a large dataset covering a broad range of topics, including the medical literature. We aim to examine its accuracy and reproducibility in answering patient questions regarding bariatric surgery.
Materials And Methods: Questions were gathered from nationally regarded professional societies and health institutions as well as Facebook support groups.
Background/aims: Patients with cirrhosis and hepatocellular carcinoma (HCC) require extensive and personalized care to improve outcomes. ChatGPT (Generative Pre-trained Transformer), a large language model, holds the potential to provide professional yet patient-friendly support. We aimed to examine the accuracy and reproducibility of ChatGPT in answering questions regarding knowledge, management, and emotional support for cirrhosis and HCC.

Background: Little is known about mortality trends among patients with psoriasis (PsO) and psoriatic arthritis (PsA) in the United States.
Objectives: To ascertain mortality trends of PsO and PsA between 2010 and 2021, focusing on the effects of the COVID-19 pandemic.
Methods: We collected data from the National Vital Statistic System and calculated age-standardized mortality rates (ASMR) and cause-specific mortality for PsO/PsA.
