Aim: After radical prostatectomy, PSA levels that reach near zero values in less than 14 days are associated with a favourable prognosis. The aim of this analysis was to investigate whether PSA also declines to near zero values after combined tele-brachytherapy.
Materials And Methods: Forty-one patient, treated with combined tele-brachytherapy for prostate cancer, were followed for at least 2 years after treatment with repeated PSA measurements.
Results: PSA values <1.0 ng/ml were only reached after 15 months; near zero PSA levels were not reached until 18-24 months after treatment (median: 0.25 ng/ml).
Conclusion: A PSA decline to near zero values occurs after definitive tele-brachytherapy, but it takes longer than after surgery (18-24 months).

The prevalence of prostate-specific antigen (PSA) testing has consistently fallen for several years. This study explored how the decreasing trend differs by selected variables and reasons for taking the PSA test. Analyses involved men, aged 40 years or older, who completed the Behavior Risk Factor Surveillance System (BRFSS) survey in even number years from 2008 through 2022.

Background: Benzodiazepines are the third most misused medication, with many patients having their first exposure during a surgical episode. We sought to characterize factors associated with new persistent benzodiazepine use (NPBU) among patients undergoing cancer surgery.
Patients And Methods: Patients who underwent cancer surgery between 2013 and 2021 were identified using the IBM-MarketScan database.

Background: Metastatic prostate cancer (PCa) has much lower survival and ultimately develops castration resistance, which expects novel targets and therapeutic approaches. As a result of iron-dependent lipid peroxidation, ferroptosis triggers programmed cell death and has been associated with castration-resistant prostate cancer (CRPC).
Subjects: To better understand how ferroptosis can be used to treat CRPC, we reviewed the following: First, ferroptosis mechanisms and characteristics.

Prostate cancer, a common malignancy in older men, often requires laparoscopic radical prostatectomy, considered the gold standard treatment. However, postoperative complications can significantly impact quality of life and psychological well-being. The emergence of mobile internet health management offers a promising approach for accessible and effective post-discharge care.

Carbon dots (CDs) are versatile nanomaterials that are considered ideal for application in bioimaging, drug delivery, sensing, and optoelectronics owing to their excellent photoluminescence, biocompatibility, and chemical stability features. Nitrogen doping enhances the fluorescence of CDs, alters their electronic properties, and improves their functional versatility. N-doped CDs can be synthesized via solvothermal treatment of carbon sources with nitrogen-rich precursors; however, systematic investigations of their synthesis mechanisms have been rarely reported.
