Clinical trials

In this study, the investigators want to examine the effects of intravenous anesthetic drugs and gases on cognitive functions in the postoperative period in individuals who will undergo surgery for obesity. The investigators believe that the anesthesia method we apply with inhalation gases is also as reliable method as total intravenous anesthesia for postoperative cognitive functions in these patients who undergoe sleeve gastrectomy. The anesthesia method applied intravenously and with inahalational gases have been applied safely for many years. Comparisons between these two anesthesia technics in obese individuals and for postoperative cognitive dysfunctions are limited. Studies on the examination of cognitive functions in postoperative patients have gained momentum with the use of neuropsychiatric tests performed on patients who have undergone cardiac surgery and these tests have also been performed on individuals who have undergone non-cardiac surgery. And yet, similar declines in cognitive functions have been observed. For these reasons, the effects of surgery itself and anesthesia methods on cognitive functions have been studied up to date. In this study, the investigators plan to evaluate patients who will undergo obesity surgery in both anesthesia methods by the recovery times from anesthesia and the residual effects of anesthesia, and after awakening they plan to evaluate their cognitive functions with neuropsychiatric tests that will be performed at certain intervals.

Stroke is one of the leading causes of mortality and disability worldwide. A proportion of individuals who experience a stroke fail to achieve the desired level of motor recovery in the affected upper extremity following rehabilitation, resulting in significant limitations in activities of daily living. After stroke, rehabilitation programs are essential to reduce disability and enhance functional outcomes. This study aims to evaluate whether the addition of Motor Imagery (MI) to a standard rehabilitation program contributes to improvements in upper extremity motor function in individuals with stroke. MI is a mental practice technique in which individuals cognitively rehearse movements without physically performing them. Although the movement is not executed, the brain regions involved in the movement are activated. Eligible participants will be randomly assigned to three groups. All groups will receive a standard physical therapy and rehabilitation program. The first group will receive only standard physical therapy and rehabilitation. The second group will receive, in addition to conventional therapy, 15 minutes of MI training three days per week, while the third group will receive 15 minutes of MI training five days per week. The total treatment duration for all groups is planned as 30 sessions. Assessments will be conducted at baseline, at the end of the treatment period, and again at the 12th week. This study is based on the hypothesis that adding MI practice to a conventional upper extremity rehabilitation program after stroke will contribute to improvements in activities of daily living and functional recovery, and that these effects may be associated with the frequency of the intervention.

This prospective observational single-center study will compare the effects of ultrasound-guided meta-PENG block and suprainguinal fascia iliaca plane block in patients undergoing hip fracture surgery under spinal anesthesia. Hip fracture surgery can cause significant pain before, during, and after the operation. Regional anesthesia techniques may help reduce pain, improve positioning for spinal anesthesia, decrease the need for additional analgesics, and support earlier mobilization. Patients included in the study will be adults scheduled for hip fracture surgery under spinal anesthesia. According to routine clinical practice and the anesthesiologist's decision, patients will receive either ultrasound-guided meta-PENG block or ultrasound-guided suprainguinal fascia iliaca plane block. The study will not assign patients to a treatment group by randomization. The main outcome will be pain during positioning for spinal anesthesia, measured using the Numeric Rating Scale. Additional outcomes will include postoperative pain at rest and during activity, additional analgesic consumption, patient satisfaction, mobilization time, and length of hospital stay.

This study aims to investigate the effect of specific exercise programs on individuals suffering from cervicogenic headaches, a type of headache originating from neck problems. While traditional physiotherapy is the standard approach, this research examines whether the addition of specific "fascia-focused" exercises or "breathing exercises" provides improved relief. Fascia is a thin, protective membrane layer surrounding every muscle and organ in the body. In this study, participants will be divided into three groups. All participants will receive standard neck exercises and posture training. One group will perform dynamic exercises targeting the body's connective tissue (fascia) to improve flexibility and coordination. Another group will practice specific breathing techniques to help reduce muscle tension and stress-related triggers. The exercises will be administered to participants for 12 weeks. It is expected that fascia exercises and breathing exercises will have positive effects on headaches as a result of the applied treatments.

Menopause is a natural stage in a woman's life that can be associated with symptoms such as hot flashes, night sweats, sleep problems, and vaginal dryness. Menopausal hormone therapy is commonly used to relieve these symptoms. In women with an intact uterus, progesterone must be used together with estrogen to protect the lining of the uterus. The purpose of this study is to compare two commonly used progesterone treatment methods in women receiving menopausal hormone therapy. All participants will use transdermal estradiol gel, and they will be randomly assigned to receive either oral dydrogesterone or vaginal micronized progesterone. This prospective randomized controlled study will evaluate the effects of these treatments on endometrial thickness, menopausal symptoms, vaginal health parameters, bleeding patterns, and quality of life over a 12-month follow-up period. The results of this study may help determine the most appropriate progesterone regimen for women undergoing menopausal hormone therapy.

Hashimoto's thyroiditis (HT) is the most common autoimmune thyroid disease and is increasingly recognized as a condition associated with chronic low-grade systemic inflammation beyond thyroid hormone dysfunction. The soluble α-Klotho-fibroblast growth factor 23 (FGF23) axis plays a central role in mineral metabolism, inflammation, and aging-related pathways; however, its involvement in HT has not been adequately characterized. This prospective case-control study aims to compare serum soluble α-Klotho and FGF23 levels between adults with Hashimoto's thyroiditis and age- and sex-matched healthy controls, and to investigate their associations with thyroid function parameters, inflammatory markers, and autoimmune burden. In addition, the FGF23/sKlotho ratio will be evaluated as an integrated marker of functional imbalance within the Klotho-FGF23 axis. The study seeks to determine whether Hashimoto's thyroiditis is associated with systemic dysregulation of the Klotho-FGF23 pathway independent of renal function and mineral metabolism.

People living with HIV are experiencing longer life expectancy due to effective antiretroviral therapy; however, they may develop age-related conditions earlier than the general population. This prospective observational study aims to evaluate frailty, sarcopenia, nutritional status, cognitive function, and functional performance in adults aged 40 years and older living with HIV and to compare them with age- and sex-matched healthy controls.

This study compares two treatment approaches for pilonidal sinus disease: laser treatment alone versus laser treatment combined with phenol application. Pilonidal sinus is a common condition that affects young adults and can cause significant discomfort and time off work. Participants will be randomly assigned to receive either laser treatment only (Group A) or laser treatment plus phenol application (Group B). Both treatments are minimally invasive and performed under local anesthesia as day surgery procedures. The main goal is to determine if adding phenol to laser treatment speeds up the healing process (epithelialization) and improves patient outcomes. We will measure healing time, pain levels, return to daily activities, and quality of life over a 3-month follow-up period. This research may help develop more effective treatment protocols that reduce healing time and improve patient comfort for people with pilonidal sinus disease.

Laparoscopic cholecystectomy, while less painful compared to conventional methods, is still a surgery that can cause significant pain for patients. Preventing postoperative pain is crucial for reducing respiratory complications, shortening hospital stays, and increasing patient satisfaction. Interfascial plane blocks have been widely used for postoperative analgesia in recent years worldwide. The External Oblique Intercostal Plane Block is one of the interfascial plane blocks used in abdominal surgeries. In our study, we aimed to compare the postoperative pain scores of patients who underwent laparoscopic cholecystectomy under general anesthesia, specifically between those who received the external oblique intercostal plane block and those who had trocar entry site infiltration.

Although there are many methods for the surgical treatment of pilonidal sinus disease, the number of studies specific to women is limited in the literature. In addition to post-treatment recurrence and complication rates in women, aesthetic results are also of great importance. This study will compare the Karydakis procedure, a flap method, and the Bascom's pit-pick procedure, a minimally invasive procedure, in terms of recurrence, complications and aesthetics, especially in female patients with three or fewer pits.

Pilonidal sinus disease is a common condition, and treatment options and outcomes vary greatly. Chronic symptomatic pilonidal sinus disease (PSD) primarily affects young adults and causes work loss. In this study, three treatment methods will be performed: the minimally invasive pit-picking procedure, crystallized phenol application (CPT), and a combined method (minimally invasive pit-picking procedure and CPT). The aim of this study is to compare the effectiveness of these three methods, evaluate short- and long-term results, and determine treatment success, the incidence of postoperative complications, chronic pain levels, recurrence rates, and patient satisfaction. Additionally, the effects of these methods on hospital stay, wound healing time, and workforce loss will also be examined.
