Clinical trials

Ulcerative colitis is a chronic disease with a significant impact on quality of life where a substantial proportion of patients fails to achieve disease remission. It is a multifactorial disease, and the influence of diet on its onset and course remains underexplored. Favorable effects of the Mediterranean diet on numerous diseases have been confirmed in clinical research, but in the case of ulcerative colitis, there is a lack of well-designed studies. The aim of this study is to demonstrate that a modified Mediterranean diet (MMD) with reduced carbohydrate intake over a duration of 12 weeks, in conjunction with standard therapy, has a favorable impact on symptoms and objective markers of inflammation in ulcerative colitis patients. A prospective randomized study will involve participants divided into a control and an intervention group. Over the course of 12 weeks, they will adhere to MMD under nutritionist guidance or follow standard dietary recommendations.

This study looks at how dry eye disease can affect important eye measurements needed before cataract surgery. These measurements guide us in choosing the right artificial lens to implant, which is essential for achieving clear vision after the procedure. We are currently investigating whether patients with dry eyes tend to have less reliable readings due to surface irregularities on the eye. Our goal is to better understand this connection so we can improve pre-surgical preparation for patients with dry eye and help ensure better visual outcomes after cataract surgery.

This clinical study involves patients with Dry Eye Disease (DED) who are visiting an ophthalmology outpatient clinic. Eligible participants must have an Ocular Surface Disease Index (OSDI) score ≥14 and \<50, and at least one positive diagnostic test: tear break-up time (TBUT) \<7 seconds, Schirmer I test \<10 mm/5 min, or positive corneal staining based on the Oxford grading scale. At baseline, tear film thickness will be measured using Pentacam imaging. Participants will then receive Proluxx eye spray, applied four times daily for 28 days. After this treatment period, a follow-up examination with all baseline assessments will be repeated.

The standard therapy for acute ischemic posterior circulation stroke (PCS) often leads to poor functional outcomes and high mortality rates, despite all advances in reperfusion therapy. Recent trials have shown that adding Cerebrolysin, a cerebral neuroprotective agent, to standard therapy for patients with acute ischemic anterior circulation stroke is safe and leads to improved functional outcomes. The purpose of this study is to assess the effectiveness and safety of Cerebrolysin with standard treatment for patients with PCS secondary to basilar artery occlusion (BAO). The plan is to conduct a prospective, single-center, single-arm, open-label study with 20 acute basilar artery occlusion patients and premorbid modified Rankin Score (mRS) ≤3, treated with standard treatment (mechanical thrombectomy ± intravenous alteplase or conservative treatment) and Cerebrolysin as add-on therapy, compared with historical controls. Besides standard acute stroke assessment, standard treatment, and rehabilitation, the participants who meet the eligibility criteria will receive Cerebrolysin in a single-day dosage of 30 ml intravenously for 14 consecutive days. The participants will be closely monitored, and neuroimaging findings and clinical outcomes will be obtained during the drug administration period, on discharge, one month, and 3 months after the treatment onset. The primary endpoints are mRS (0-3) on day 90 and mortality rate 90 days after the stroke onset. The secondary endpoints are defined as a change in any type of intracerebral bleeding and a change of min. 2 points on the National Institutes of Health Stroke Scale 24 hours, 14 days, 30 days, and 90 days post-stroke. The investigators hypothesize that adding Cerebrolysin to standard stroke treatment will improve clinical outcomes and reduce morbidity and mortality in patients with acute basilar occlusion compared to standard treatment alone.

This is a prospective observation cohort investigation. Patients, that is participants, undergoing primary functional rhinoplasty will be evaluated in terms of measuring capillary blood lactic acid concentration in the nasal skin-soft tissue envelope immediately after the procedure and 7 days after the procedure. The aim of our study is to test whether or not different rhinoplasty approaches and volume of the used autologous cartilage grafts impact the nasal skin-soft tissue metabolism.
