Clinicopathologic Study of 28 Cases of Tubulocystic Renal Cell Carcinoma: Is It Time to Reclassify It as a Tubulocystic Renal Cell Tumor?

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.

Paradoxical Hypoxemia Following Positive Pressure Ventilation: Exploring the Pathophysiology.

Unlabelled: Positive pressure ventilation (PPV), both non-invasive and invasive, enhances ventilation but can sometimes lead to unexpected hypoxemia. This case report describes an instance of paradoxical hypoxemia after initiating bilevel positive airway pressure (BiPAP) in a 58-year-old female with a medical history of systemic lupus erythematosus, interstitial lung disease, and pulmonary embolism. BiPAP was started, leading to improved hypercarbia but worsened hypoxemia.

Living on the edge: Role of adjuvant therapy after resection of primary lung cancer within 2 millimeters of a T-stage cutoff.

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.

Multi-Sensor Soil Probe and Machine Learning Modeling for Predicting Soil Properties.

We present a data-driven, in situ proximal multi-sensor digital soil mapping approach to develop digital twins for multiple agricultural fields. A novel Digital Soil Core (DSC) Probe was engineered that contains seven sensors, each of a distinct modality, including sleeve friction, tip force, dielectric permittivity, electrical resistivity, soil imagery, acoustics, and visible and near-infrared spectroscopy. The DSC System integrates the DSC Probe, DSC software (v2023.

Right Upper Lobe Large Cell Neuroendocrine Carcinoma with Atypical Carcinoid Features: Case Report.

Introduction: Large cell neuroendocrine carcinoma (LCNEC) and atypical carcinoid (AC) tumor are two distinct types of pulmonary neuroendocrine tumors (NETs) that are considered genetically unrelated. AC is categorized as a well-differentiated NET, while LCNEC is considered a poorly differentiated NET with a significantly poorer prognosis.

Case Presentation: In this case report, we present an 83-year-old male who presented with 2-day history of hemoptysis and subsequently diagnosed with a right upper lobe carcinoid tumor on pre-excision biopsy.
