This publication introduces a novel open-access P Nuclear Magnetic Resonance (NMR) shift database. With 14,250 entries encompassing 13,730 distinct molecules from 3,648 references, this database offers a comprehensive repository of organic and inorganic compounds. Emphasizing single-phosphorus atom compounds, the database facilitates data mining and machine learning endeavors, particularly in signal prediction and Computer-Assisted Structure Elucidation (CASE) systems. Additionally, the article compares different models for P NMR shift prediction, showcasing the database's potential utility. Hierarchically Ordered Spherical Environment (HOSE) code-based models and Graph Neural Networks (GNNs) perform exceptionally well with a mean squared error of 11.9 and 11.4 ppm respectively, achieving accuracy comparable to quantum chemical calculations.

Positron emission tomography (PET) imaging plays a pivotal role in oncology for the early detection of metastatic tumors and response to therapy assessment due to its high sensitivity compared to anatomical imaging modalities. The balance between image quality and radiation exposure is critical, as reducing the administered dose results in a lower signal-to-noise ratio (SNR) and information loss, which may significantly affect clinical diagnosis. Deep learning (DL) algorithms have recently made significant progress in low-dose (LD) PET reconstruction.

Prostate cancer (PCa) is a leading cause of cancer-related deaths globally, with metastatic castration-resistant prostate cancer (mCRPC) posing significant treatment challenges. This case report discusses a 65-year-old male with mCRPC who initially responded to hormonal therapy but later showed disease progression despite additional chemotherapy. He subsequently received Lu-PSMA and Ac-PSMA therapies, both of which failed to halt disease progression despite having an intense PSMA avid metastatic disease.

Objectives Breastfeeding is critical for a mother's health, as well as the development and survival of her infant. Healthcare personnel are a reliable source of information for breastfeeding mothers during and after radiological procedures, assuming their understanding is appropriate. As a result, this study analyzed healthcare professionals' knowledge of breastfeeding and radiological tests on lactating mothers.

Desmoid fibromatosis (DF) is a rare, non-metastasizing but locally aggressive mesenchymal tumor arising from fibroblasts or myofibroblasts. We report a solitary case of DF involving the retropharyngeal and danger spaces, a location rarely documented. The patient, a woman in her 70s, presented with progressive pharyngeal discomfort over six months.

Macrotrabecular-massive hepatocellular carcinoma (MTM-HCC) is a rare and aggressive molecular subtype of hepatocellular carcinoma (HCC) associated with a poor prognosis. Unlike typical HCC, which commonly arises in the context of cirrhosis, MTM-HCC can develop in non-cirrhotic livers, presenting unique diagnostic and therapeutic challenges. This case report describes a 35-year-old male who presented with persistent epigastric pain, fatigue, and loss of appetite.
