Prostate cancer: Specialized imaging could prevent unnecessary biopsies

An elevated PSA level in the blood may indicate prostate cancer but does not allow for a definitive diagnosis. Where there is a corresponding suspicion, a tissue sample is usually taken from the prostate. A study by the Medical University of Vienna now shows that a specialized form of imaging—known as PSMA-PET/CT—could provide important additional information even before such a biopsy is carried out.

New ablation approach improves outcomes for persistent atrial fibrillation

Atrial fibrillation is the most common cardiac arrhythmia and increases the risk of conditions such as stroke and heart failure. An established treatment is catheter ablation, in which physicians use thin catheters to create small scars in heart tissue to block the electrical signals that cause the arrhythmia. Despite treatment, many patients with the more difficult-to-treat form, persistent atrial fibrillation, experience recurrence.

Magnetic pulses reprogram immune cells to fight breast cancer in preclinical models

Researchers from the National University of Singapore (NUS) have demonstrated an innovative approach for targeted breast cancer therapy using pulsed electromagnetic fields (PEMFs). The NUS team successfully reprogrammed tumor-associated macrophages (TAMs), a corrupted class of immune cells that typically promote cancer growth, into an active anti-tumor state that attacks and destroys cancer cells.

Blocking gene boosts T-cell attacks on chronic hepatitis B virus and tumors

A research team led by Professor Zhou Xuyu from the Institute of Microbiology of the Chinese Academy of Sciences (CAS), in collaboration with researchers from Beijing Ditan Hospital and Capital Medical University, has identified ANKRD11 as a key regulator that reduces the activity of CD8+ T cells during chronic hepatitis B virus (HBV) infection and cancer. The researchers found that ANKRD11 suppresses the AP-1 signaling pathway, which usually helps CD8+ T cells mount effective responses against infections and tumors.
