Article Synopsis
  • The Mass Spectrometry Data Center (MSDC) is enhancing libraries for identifying plastics-related compounds (PRC) and materials (PRM) as part of NIST's circular economy initiative.
  • To increase the diversity of compounds analyzed, MSDC is utilizing three ionization methods: EI, ESI, and APCI, along with pyrolysis-gas chromatography (py-GC-MS) for solid materials.
  • Collaborating with agencies like the FDA and EPA, they are testing these libraries to address health risks and environmental issues concerning plastics.

Tubulocystic renal cell carcinoma (TC-RCC) is uncommon and is defined by exclusive tubulocystic growth. Its clinicopathology is still evolving. Twenty-eight cases of so-defined TC-RCC were studied for clinicopathology as well as, in some cases, immunohistochemistry.

Article Synopsis
  • Positive pressure ventilation (PPV), particularly BiPAP, can sometimes cause unexpected hypoxemia in patients, as illustrated by a case involving a 58-year-old woman with a history of chronic lung issues.
  • The investigation revealed a right-to-left interatrial shunt due to a small patent foramen ovale (PFO), which contributed to the paradoxical hypoxemia despite improved carbon dioxide levels.
  • This case highlights the importance of understanding patient-specific conditions and the need to adjust BiPAP settings to optimize oxygen levels effectively.

Objectives: To evaluate the use of systemic therapy and overall survival in patients with resected non-small cell lung cancer whose pathologic tumor size was within 2 mm of a T-stage cutoff.

Methods: This was retrospective cohort study using the National Cancer Database of patients who underwent resection of tumors within 2 mm of the T1c/T2a, T2a/T2b, and T2b/T3 T-stage cutoffs. Patients with nodal involvement or whose T stage was determined on the basis of pathologic features other than tumor size were excluded.

Article Synopsis
  • A data-driven approach was developed to create digital twins for agricultural fields using a specialized Digital Soil Core (DSC) Probe equipped with seven different sensors, allowing for detailed soil analysis in real time at high vertical resolution.
  • The DSC System integrates the probe, software, and equipment to scan soil characteristics up to 120 cm deep in about 60 seconds, producing a data cube that captures diverse soil conditions, unlike traditional methods that suffer from lower resolution and accuracy.
  • The study conducted in California's almond orchards aimed to assess the discrepancies between high-res in situ sensor data and lower-res lab measurements to enhance soil prediction models, employing various statistical methods to analyze data integration techniques effectively.
