Introduction: Photoselective vaporisation of the prostate (PVP) is a surgical alternative to transurethral resection of the prostate (TURP). The goal of this study was to compare the new AMS MOXY fiber which provide 180 watts power to the 4090 fiber 120 watts power source currently used in benign prostatic hyperplasia. The assessment criteria were peroperative and early postoperative data.
Method: This study was a monocentric prospective trial comparing two parallel groups of treatment: prostatic vaporisation with MOXY fiber (180 watts) against 4090 fiber (120 watts) in patients operated by an experienced surgeon. The urinary catheter was removed the day after the intervention and the patient was allowed to quit after a clinical examination. All the patients had a routine consultation at 1 month: clinical examination, max flow rate, biological results and results of autoquestionnaires.
Results: This study included 50 patients. The two groups were similar at the inclusion: age, urinary catheter, and prostate volume. The operative data show a decrease of vaporization duration (29 minutes versus 36 minutes, P=0.009) with an energy delivered increased (281 kJoules versus 223 kJoules, P=0.036) and with similar postoperative data: duration of urinary catheterization (3.8 days versus 3.6 days, P=0.908), length of stay (1.6 days versus 1.8 days, P=0.371). The 1-month results were similar between the two groups.
Conclusion: The new fiber AMS 180 watts ROXY offer similar postoperative data to the 4090 fiber with improved operative duration and energy delivered.

The objective of this study was to ascertain the impact of photobiomodulation and radiofrequency on the healing of pressure injuries in mice. A total of 70 animals were randomly assigned to seven experimental groups. A pressure injury was induced in the dorsal region of the mice by the application of two magnets.

Article Synopsis
- The study investigates how typical physical activity impacts metabolism and breast cancer risk, using comprehensive assessments over a year on 707 participants aged 50-74.
- Researchers found that physical activity is linked to 164 metabolites, with 12 of these specifically associated with breast cancer risk, revealing that higher physical activity correlates with lower levels of certain metabolites that could increase breast cancer risk.
- The conclusion emphasizes that physical activity is linked to a variety of metabolites, suggesting it may play a protective role against breast cancer and highlighting possible metabolic pathways for prevention.
Importance: Supplementing potassium in an effort to maintain high-normal serum concentrations is a widespread strategy used to prevent atrial fibrillation after cardiac surgery (AFACS), but is not evidence-based, carries risks, and is costly.
Objective: To determine whether a lower serum potassium concentration trigger for supplementation is noninferior to a high-normal trigger.
Design, Setting, And Participants: This open-label, noninferiority, randomized clinical trial was conducted at 23 cardiac surgical centers in the United Kingdom and Germany.
Young adults with a history of substance use disorder experienced more negative mental health, social and economic outcomes during the COVID-19 pandemic period.

Background And Aims: For young adults, the disruptions brought by the COVID-19 pandemic to work, social relationships and health-care probably impacted normative life stage transitions. Disaster research shows that negative effects of these events can persist for years after the acute crisis ends. Pandemic-related disruptions may have been especially consequential for young adults with a history of substance use disorder (SUD).

Objective: This study examines the effect of two light-curing protocols from a LED polywave light curing unit (LCU) on water sorption, solubility, and hygroscopic expansion of fast and conventional bulk-fill resin-based composites (RBCs) aged in distilled water for 120 d.
Methods: Three bulk-fill RBCs materials were studied: Tetric PowerFill® (fast photo-polymerised composite) (TPF), Tetric EvoCeram bulk-fill (EVO), and GrandioSo x-tra bulk-fill (GSO) (conventional photo-polymerised composites). Specimens were prepared within a 3D-printed resin mold (8-mm diameter x 4-mm height) and light-cured from one side only with 2 modes of polywave LCU (Bluephase® PowerCure): 3 s mode and for 20 s in "Standard" mode.
