Surgical or chemical castration is widely used for the treatment of advanced prostate cancer. Common side effects of castration are e.g. sweating, increased body fat, decreased muscle mass, impotency and anemia. Castration increases the risk of osteoporosis and fractures in prostate cancer patients via hormonal effects to the bone. Castrated men should be recommended to increase physical activity. Calcium and vitamin-D supplementation is recommended. The European Association of Urology guidelines for prostate cancer recommend bone mineral density measurements before long-lasting castration therapy. Medical therapy should be considered for patients after low-energy fractures, after the diagnosis of osteoporosis based on bone mineral density measurements and for fracture high-risk patients based on clinical decision.

Glutaraldehyde functionalized reduced graphene oxide based resistive sensors for detection of PCA3.

Prostate cancer antigen 3 (PCA3) has emerged as a critical biomarker for the early detection of prostate cancer, complementing the traditional prostate-specific antigen (PSA) testing. This research presents a novel resistive sensor based on reduced graphene oxide (RGO) functionalized with glutaraldehyde (GA)/complementary single-stranded DNA (ss-DNA) for the detection of the PCA3 RNA. The device was meticulously characterized at each fabrication step to confirm the successful integration of the various layers on the sensor device, utilizing atomic force microscopy (AFM) which confirmed the increase in the thickness of the sensor from ∼1.

Poly(adenosine diphosphate ribose) polymerase (PARP) inhibitors, such as olaparib, talazoparib, rucaparib, and niraparib, comprise a therapeutic class that targets PARP proteins involved in DNA repair. Cancer cells with homologous recombination repair defects, particularly BRCA alterations, display enhanced sensitivity to these agents because of synthetic lethality induced by PARP inhibitors. These agents have significantly improved survival outcomes across various malignancies, initially gaining regulatory approval in ovarian cancer and subsequently in breast, pancreatic, and prostate cancers in different indications.

Transrectal (TR) biopsy has traditionally been the gold standard for diagnosis, but transperineal (TP) biopsy is increasingly favoured due to its lower infection risk. However, debate remains regarding which method has superior cancer detection rates.

There is a stark disparity in the uptake of HF between North America and Africa. Using the Consolidative Framework for Implementation Research, we evaluated barriers and facilitators for implementing HF in Sub-Saharan Africa (SSA).

Background: Prostate-specific membrane antigen (PSMA) has shown to be a promising agent for prostate cancer imaging under PET-CT. With the automation in radiolabeling with 68Ga, using iTG 68Ge/68Ga generator, it has helped introduce various new diagnostic agents and achieve good manufacturing practices (GMP) simultaneously. However, before any radiopharmaceutical is put into clinical usage, it should always be checked for its radiochemical purity and other quality parameters before injecting in the patient.
