NCT07294586
This is a 24-month, monocentric, exploratory and observational clinical study aimed at developing and validating a blood-based diagnostic test for Alzheimer's disease (AD). The test is based on two complementary biomarkers: conformational changes in Protein Kinase C (PKC) and aggregation of β-amyloid peptide on red blood cell membranes. The study will also establish a biobank of serum, plasma, urine, and RNA samples for future biomarker research.
NCT07295041
This study aimed to compare two different methods used to augment bone in the posterior lower jaw prior to implant placement in patients with insufficient bone width. Eligible patients were included in the study and received a horizontal bone augmentation with one of two methods, which differed in the materials used for the bone augmentation. The group allocation was randomised. After 6 months of healing following parameters were assessed: histological evaluation, survival of the bone graft, the need for further bone augmentation at the time of implant placement, changes in soft tissue characteristics, radiologically and clinically assessed changes in bone width.
NCT07294040
This observational clinical study aims to investigate the incidence and risk factors of post-induction hypotension (PIH) in geriatric cancer patients undergoing surgery under general anesthesia. PIH is defined as a drop in mean arterial pressure of ≥30% from baseline or below 65 mmHg within the first 20 minutes after anesthesia induction, prior to surgical stimulation. The primary objective is to determine the frequency of PIH in elderly oncology patients. Secondary objectives include evaluating the association of PIH with age, ASA score, cancer type, oncological treatments (chemotherapy/radiotherapy), comorbidities, medication use, anemia, biochemical parameters, and preoperative perfusion index (PI) and pleth variability index (PVI). Findings from this study are expected to contribute to improved perioperative management and to the development of tailored anesthesia protocols for geriatric oncology patients.
