AI Article Synopsis

  • A case of metachronous transitional cell carcinoma (TCC) of the prostatic urethra was reported in a 56-year-old male patient with a history of nephroureterectomy for urothelial neoplasia.
  • Cystourethroscopy revealed suspicious lesions leading to a diagnosis of high-grade superficial TCC, followed by BCG instillation and reevaluation procedures.
  • Despite treatment, the cancer progressed to infiltrating TCC with lymph node involvement, and chemotherapy proved ineffective, highlighting the aggressive nature and poor prognosis of such cases.

Article Abstract

Objectives: We report one case of Metacronous transitional cell carcinoma (TCC) of the prostatic urethra in a patient with history of left nephroureterectomy 22 years before for urothelial neoplasia of the upper urinary tract.

Methods: We describe the case of a 56-year-old male patient who presents with oligosymptomatic hematuria for several months. Cystourethroscopy showed irregular hyperemic lesions in the prostatic urethra, cold biopsy of which showed urothelial atypia. Pathology report of fragments of a posterior transurethral resection (TUR) was compatible with high-grade superficial transitional cell neoplasia. Instillation of Bacillus Calmette-Guerin (BCG) was indicated. Reevaluation TUR was performed.

Results: Pathologic report of new samples showed TCC infiltrating the prostatic stroma. The extension study showed ilioobturator adenopathies. Chemotherapy did not achieve significant results. Radical surgery was rejected.

Conclusions: We emphasize the notable metachronous character of the transitional cell carcinoma of the prostatic urethra with respect to the upper urinary tract TCC. We also point out the metastasic capacity of these neoplasias, as well as the bad prognosis of those cases in which chemotherapy is not effective.

NS1 binding protein regulates stress granule dynamics and clearance by inhibiting p62 ubiquitination.

The NS1 binding protein, known for interacting with the influenza A virus protein, is involved in RNA processing, cancer, and nerve cell growth regulation. However, its role in stress response independent of viral infections remains unclear. This study investigates NS1 binding protein's function in regulating stress granules during oxidative stress through interactions with GABARAP subfamily proteins.

E-cigarette/vaping-associated lung injury (EVALI) is strongly associated with vitamin E acetate and often occurs with concomitant tetrahydrocannabinol (THC) use. To uncover pathways associated with EVALI, we examined cytokines, transcriptomic signatures, and lipidomic profiles in bronchoalveolar lavage fluid (BALF) from THC-EVALI patients. At a single center, we prospectively enrolled mechanically ventilated patients with EVALI from THC-containing products (N = 4) and patients with non-vaping acute lung injury and airway controls (N = 5).

Biological systems are complex, encompassing intertwined spatial, molecular and functional features. However, methodological constraints limit the completeness of information that can be extracted. Here, we report the development of INSIHGT, a non-destructive, accessible three-dimensional (3D) spatial biology method utilizing superchaotropes and host-guest chemistry to achieve homogeneous, deep penetration of macromolecular probes up to centimeter scales, providing reliable semi-quantitative signals throughout the tissue volume.

Human adenovirus (HAdV) is a widely spread respiratory pathogen that can cause infections in multiple tissues and organs. Previous studies have established an association between HAdV species B (HAdV-B) infection and severe community-acquired pneumonia (SCAP). However, the connection between SCAP-associated HAdV-B infection and host factor expression profile in patients has not been systematically investigated.
