Background: Robotic systems are increasingly utilised to improve clinical outcomes in prostate interventions.
Methods: We enroled 20 patients to verify the clinical feasibility of transrectal ultrasound (TRUS)-guided robot-assisted prostate biopsy (PBx). For each patient, controlled trials of systematic 12-core PBx were initially conducted manually using a biopsy gun, followed by a 3-core cognitive fusion targeted biopsy performed by the hand-held robot.
Results: The targeting errors for robot-assisted biopsy and freehand biopsy were 3.71 ± 1.41 mm and 3.94 ± 1.49 mm, respectively. Their cancer core rates were 19.1% and 12.6%, and the average duration of each biopsy was 6.94 min and 1.62 min, respectively.
Conclusions: The robot's sampling success rate was lower than that of freehand with a biopsy gun in the clinical trial. However, robot-assisted PBx has shown improved cancer core rate, slightly enhanced surgical accuracy, and the capability to reach clinically significant tumours' 5 mm error range, all demonstrating its clinical value.

Importance: Excess body fat plays a pivotal role in the pathogenesis of heart failure with preserved ejection fraction (HFpEF). HU6 is a novel, controlled metabolic accelerator that enhances mitochondrial uncoupling resulting in increased metabolism and fat-specific weight loss.
Objective: To assess efficacy and safety of HU6 in reducing body weight, improving peak volume of oxygen consumption (VO2) and body composition among patients with obesity-related HFpEF.

Importance: Exercise intervention studies have shown benefits for patients with lung cancer undergoing surgery, yet most interventions to date have been resource intensive and have followed a one-size-fits-all approach.
Objective: To determine whether a personalized, clinic-aligned perioperative exercise program with remote monitoring and instructions can improve physical function and fatigue among patients undergoing surgery for lung cancer.
Design, Setting, And Participants: The Precision-Exercise-Prescription (PEP) randomized clinical trial is a single-center phase 3 trial.
Exercise and Psychosexual Education to Improve Sexual Function in Men With Prostate Cancer: A Randomized Clinical Trial.

Importance: Sexual dysfunction is a common adverse effect of prostate cancer treatment, and current management strategies do not adequately address physical and psychological causes. Exercise is a potential therapy in the management of sexual dysfunction.
Objective: To investigate the effects of supervised, clinic-based, resistance and aerobic exercise with and without a brief psychosexual education and self-management intervention (PESM) on sexual function in men with prostate cancer compared with usual care.
