NCT ID: NCT05811182 Completed - Clinical trials for Cystoid Macular Edema Following Cataract Surgery

Vitreous Hyper Reflective Dots in Association With Pseudophakic Cystoid Macular Edema

Start date: July 1, 2018
Phase:
Study type: Observational

The aim of this study is to assess the association between vitreous hyper-reflective dots (VHD) and the macular thickness changes following uneventful phacoemulsification. In this prospective study the investigators performed optical coherence tomography (OCT) imaging in patients undergoing cataract surgery preoperatively and postoperatively after 1 week, 1 month and 3 months and analyzed the OCTs for VHDs. The investigators then measured the macular thickness in patients with VHDs and without VHDs and correlated the macular thickness with the number of VHDs.

NCT ID: NCT05779306 Completed - Clinical trials for Cataract Complicated

Performance of Two Sclera Fixated Intraocular Lens Concepts

Carlevale
Start date: January 19, 2023
Phase:
Study type: Observational

To evaluate and compare the post-operative outcome of two different sceral fixated IOL concepts, the Yamane method (ZA9003, J&J, USA) and the Carlevale IOL (FIL-SSF, Soleko, Italy).

NCT ID: NCT05775536 Completed - Dry Eye Clinical Trials

Detection of Acetylsalicylic Acid and Omega-3 Fatty Acids in Schirmers' Test Strips Using Mass Spectrometry

Start date: January 21, 2021
Phase: Phase 2
Study type: Interventional

Evaluation of tear fluid production using Schirmers' tests is a well-known and frequently used examination method in ophthalmology. Schirmers' test objectively indicates the tear fluid production over five minutes by insertion of a filter paper strip in the lower conjunctival fornix. Commonly, this method is used to quantify tear fluid production, but not tear fluid composition. The development of novel, very precise analytical methods opens up new possibilities in the use and application of Schirmers' test strips. A recently introduced analytical method is mass spectrometry. This method allows the detection and quantification of proteins, lipids, and metabolites in very low amounts of samples. Whether systemically ingested agents such as omega-3 fatty acids or acetylsalicylic acid can be detected in tear fluid using this method remains unclear. The aim of this study is to investigate the detectability of 2 different agents (acetylsalicylic acid and omega-3 fatty acids) in Schirmers' test strips from healthy subjects after intake for 1 week by use of untargeted mass spectrometry. Participating healthy subjects will receive either acetylsalicylic acid or omega-3 fatty acids.

NCT ID: NCT05754424 Completed - Clinical trials for Diabetes Mellitus, Type 2

AT278, NovoRapid® and Humulin® R (U500) in Glucose Clamp Study

Start date: February 27, 2023
Phase: Phase 1
Study type: Interventional

This is a phase 1, single dose, randomised, double-blind, two-way crossover study to compare ultra-rapid-acting concentrated insulin aspart AT278 (U500/mL) with standard insulin aspart NovoRapid® (U100/mL) in participants with T2D. Participants and Investigators will be blinded to both study interventions. Humulin® R U-500 (U500/mL), a highly concentrated regular human insulin, will be used as an open-label comparator.

NCT ID: NCT05721079 Completed - Clinical trials for Lung Transplant Rejection

Extracorporeal Photopheresis (ECP) After Lung Transplantation

Start date: March 1, 2017
Phase: N/A
Study type: Interventional

The purpose of this study is to investigate the use of ECP for lung-transplanted patients to reduce the occurrence of acute and chronic rejection and CMV-infection.

NCT ID: NCT05705596 Completed - Hunger Clinical Trials

Impact of Hesperetin in Combination With Sucrose on Energy Metabolism

Start date: January 31, 2023
Phase: Early Phase 1
Study type: Interventional

The aim of this cross-over intervention study is to investigate the influence of the sweet-modulating substance hesperetin in combination with sucrose in comparison to an equally sweet-tasting sucrose-only solution on markers of energy metabolism.

NCT ID: NCT05690893 Completed - Cataract Surgery Clinical Trials

Crystalline Lens Tilt Evaluation Using Swept-source Optical Coherence Tomography

PhysTilt
Start date: February 1, 2023
Phase:
Study type: Observational

The goal of this retrospective study is to quantify the physiological lens tilt of the phakic eye. The main question it aims to answer is: -What influence does misalignment or tilting of IOLs have on visual quality? Preoperative biometry data are compared with anterior segement OCT data. Measurements were obtained using high-resolution swept-source optical coherence tomography. The influence of biometric measurements on tilt is analyzed.

NCT ID: NCT05679635 Completed - Clinical trials for Continuous Positive Airway Pressure

Evaluation of Tracheal Pressure During CPAP

Start date: November 24, 2022
Phase: N/A
Study type: Interventional

This trial evaluates tracheal pressure values in intubated intensive care unit patients during continuous positive airway pressure without any ventilatory support, automatic tube compensation and assisted spontaneous breathing.

NCT ID: NCT05664776 Completed - Lower Back Pain Clinical Trials

Effect of Dynamic Sitting on Pain Development

DynSit-Pain
Start date: December 5, 2022
Phase: N/A
Study type: Interventional

Worksite based prolonged static sitting postures can cause musculoskeletal pain. While the development of pain increases due to the constant growth of digitalization at work, numerous interventions to reduce prolonged sitting periods have been created. The effects of such interventions have not yet been properly examined. Thus, the "DynSit-Pain" project was initiated to investigate the influence of dynamic sitting on the pain development of pain developers in office environments.

NCT ID: NCT05648929 Completed - Wounds and Injuries Clinical Trials

Experimental and Clinical Investigation of the Implant Surface Roughness Reduction Effect on Early-stage Fibrosis

Start date: January 20, 2021
Phase: N/A
Study type: Interventional

The goal of this single-center, randomised double-blinded trial is to compare the early stage fibrosis progression around conventional textured expander and the SmoothSilk® expander with reduced surface roughness in women undergoing bilateral nipple or skin sparing mastectomy in a prophylactic setting followed by tissue-expander based breast reconstruction. Researchers will compare intra-individually, the conventional textured expander CPX®(Mentor) and the SmoothSilk® (Motiva) expander (i) to gain a comprehensive insight into immunological mechanisms occurring at the timepoint of expander insertion (within the first days after implantation) based on WBF analysis in vitro, (ii)to determine the role and function of immune cells in a rather early stage of capsule formation (6-8 months after implantation) and under well-defined conditions in humans as well as (iii)to analyze the aesthetic outcome and clinical parameters after bilateral implant-based reconstruction using two expanders with varying surface topography within the individual patient (intra-individually).
