A recent report from investigators at the University of Siena in Italy explores the use of antioxidants as a supplement in the cryopreservation of human semen. Cryopreservation is an important technique for preserving male fertility, but the quality of thawed spermatozoa is often poor due to various stressors during the freezing-thawing process. Oxidative stress, caused by an overproduction of reactive oxygen species, can damage sperm and impair their function. The review analyzes studies from 2000 to the present that investigate the effects of different antioxidant compounds, including natural extracts, on sperm cryo-damages. While many studies have reported beneficial effects, improvements are not always consistent. The researchers suggest that new strategies are needed to minimize damages and increase sperm cryostability for successful clinical application. [Extracted from the article]

Researchers from the University of Siena in Italy conducted a randomized clinical study to evaluate the effectiveness of glycine-powder air-polishing (GPAP) as an adjunctive treatment for peri-implant mucositis. The study included 52 patients and 157 implants, with participants receiving either full-mouth ultrasonic debridement (Fm-UD) alone or Fm-UD with GPAP. The primary outcomes measured were complete disease resolution (DR1) and partial disease resolution (DR2). The results showed that both groups experienced a significant reduction in bleeding and plaque levels, but there was no significant difference in disease resolution between the two treatment groups. The study suggests that GPAP may not have an additional benefit in achieving disease resolution compared to Fm-UD alone. [Extracted from the article]

A study conducted by the University of Siena in Italy examined right ventricular (RV) dysfunction and pulmonary uncoupling in patients with acute heart failure (AHF). The study included 380 patients with AHF, with 235 having AHF with reduced left ventricular ejection fraction (AHFrEF) and 145 having AHF with preserved left ventricular ejection fraction (AHFpEF). The researchers measured various parameters related to RV function, such as pulmonary artery systolic pressure, tricuspid annular plane systolic excursion, and RV end-diastolic diameter. The study found that different prognostic parameters were associated with poor outcomes depending on the level of left ventricular ejection fraction. In patients with AHFpEF, certain parameters had a protective prognostic value, while in patients with AHFrEF, other parameters were related to adverse outcomes. The study concluded that S' wave and S'/PASP were associated with adverse outcomes in patients with preserved left ventricular ejection fraction, while reduced tricuspid annular plane systolic excursion and TAPSE/PASP were better prognostic predictors in patients with reduced left ventricular ejection fraction.
