Clinical trials

Male infertility contributes significantly to infertility, particularly in advanced paternal age men where sperm DNA fragmentation is increased. Conventional density gradient centrifugation may induce oxidative stress and sperm damage. LensHooke® CA0 is a centrifugation-free sperm sorting device designed to improve sperm quality and reduce DNA fragmentation. This prospective comparative study evaluates the effectiveness of CA0 versus conventional density gradient centrifugation on post-processing sperm quality, DNA fragmentation index, blastocyst formation, euploid embryo rate, and clinical pregnancy outcomes in IVF/ICSI cycles involving men aged 40 years or older

This randomized controlled trial will compare two starting doses of follicle-stimulating hormone (FSH), 225 IU and 300 IU, during progestin-primed ovarian stimulation (PPOS) in women undergoing in vitro fertilization (IVF) who have a good reproductive prognosis. Participants will be randomly assigned to receive either 225 IU or 300 IU of FSH at the start of ovarian stimulation. The study will evaluate whether the starting FSH dose affects oocyte and embryo outcomes, with blastocyst formation as the primary outcome. Other outcomes will include oocyte morphology, fertilization, embryo development, and embryo quality. The findings may help determine an appropriate starting FSH dose for women with a good prognosis undergoing IVF using the PPOS protocol.

Acute respiratory distress syndrome (ARDS) in its moderate to severe forms is associated with high mortality. Mechanical ventilation (MV) remains the cornerstone of ARDS management but carries a significant risk of ventilator-induced lung injury (VILI). Positive end-expiratory pressure (PEEP), a fundamental component of MV, is widely utilized in clinical practice; however, optimal PEEP selection for patients with moderate to severe ARDS remains a complex and unresolved challenge. Electrical impedance tomography (EIT), a bedside imaging modality that evaluates regional ventilation distribution, offers a means of individualizing PEEP settings in mechanically ventilated patients. By balancing the competing risks of alveolar overdistension and collapse, EIT facilitates precision in PEEP titration. This study compares the impact of EIT-guided PEEP selection versus the conventional low FiO2-PEEP table on blood oxygenation and pulmonary mechanics.
