Hematuria in the ER patient: optimizing detection of upper tract urothelial - A pictorial essay.

Upper tract urothelial carcinoma (UTUC) is a rare and challenging subset of the more frequently encountered urothelial carcinomas (UCs), comprising roughly 5-7% of all UCs and less than 10% of all renal tumors. Hematuria is a common presenting symptom in the emergency setting, often prompting imaging to rule out serious etiologies, with UTUC especially posing as a diagnostic challenge. These UTUC lesions of the kidney and ureter are often small, mimicking other pathologies, and are more aggressive than typical UC of the bladder, emphasizing the importance of timely and accurate diagnosis.

The study of land cover dynamics and the valuation of ecosystem services in coastal cities is pivotal for guiding sustainable urban development and conserving natural resources amidst the unique challenges posed by their geographical and ecological contexts. This study utilizes a 30 m × 30 m land use/cover change (LUCC) dataset to elucidate the spatiotemporal evolution of LUCC and ecosystem service value (ESV) and the trade-offs and synergistic relationships among ecosystem services in the coastal city of Qingdao under three different scenarios over the past 35 years and in the future based on the dual perspective of the past-future by using the equivalent factor approach (EFA), the PLUS model, and Spearman's rank correlation coefficient. The findings reveal a pronounced expansion in built-up areas in Qingdao from 1985 to 2020, with a concomitant significant reduction in cropland, leading to a fluctuation in the total ESV, which initially increased and then declined.

Background: The "Healthy China" initiative, along with advancements in technology for cancer diagnosis and treatment, has significantly enhanced outcomes for patients with gynecologic tumors. The trends of late marriage and delayed childbirth have led to an increasing number of women diagnosed with gynecologic cancers who are seeking fertility preservation in China. This issue is critical yet often overlooked in clinical practice.

Department of Radiology, Seoul National University College of Medicine, Seoul National University Hospital, Seoul, Republic of Korea.
Objective: This study aimed to develop an open-source multimodal large language model (CXR-LLaVA) for interpreting chest X-ray images (CXRs), leveraging recent advances in large language models (LLMs) to potentially replicate the image interpretation skills of human radiologists.
Materials And Methods: For training, we collected 592,580 publicly available CXRs, of which 374,881 had labels for certain radiographic abnormalities (Dataset 1) and 217,699 provided free-text radiology reports (Dataset 2). After pre-training a vision transformer with Dataset 1, we integrated it with an LLM influenced by the LLaVA network.
Prognostic factors of the survival of pancreatic cancer patients in peninsular Malaysia: A survival analysis.

Introduction: Pancreatic cancer incidence in Malaysia is steadily on the rise, now ranking as the 14th most common malignancy in the country. Despite this upward trend, research on prognostic factors affecting pancreatic cancer survival remains limited, highlighting the need for ongoing investigation to improve patient survival outcomes.
Materials And Methods: This study was conducted retrospectively by reviewing records of pancreatic cancer patients hospitalized between January 2011 and December 2018 across multiple health centres in Malaysia.
