NCT04585074
Robotic mastectomy and immediate reconstruction have been introduced in 2015. However, since robotic mastectomy is the latest surgical technique, there is a lack of studies prospectively comparing conventional mastectomy and immediate reconstruction with robotic mastectomy. For this reason, this study is designed to establish a single institution cohort study that prospectively collects patients undergoing mastectomy and reconstruction. This study was initially designed as a single institution study, however, currently, the study was extended to the multicenter study including 18 institutions over the country. Using the established prospective cohort data, a comparative study of robotic mastectomy with conventional mastectomy and reconstruction, and cost-effectiveness and satisfaction of robotic endoscopic surgery, and cost-effectiveness and satisfaction of reconstructive surgery are to be analyzed.

NCT06324097
Colorectal cancer (CRC) is the third most common malignancy and the second leading cause of cancer-related death worldwide. Colonoscopy is considered the preferred method of screening for colorectal cancer, and resection of colorectal lesions can significantly reduce the incidence and mortality of colorectal cancer. In order to improve the qualitative and quantitative diagnosis of colorectal lesions, many endoscopic techniques, such as image-enhanced endoscopy (IEE), including narrowband imaging (NBI), magnifying endoscopy, pigment endoscopy, confocal laser endoscopy, and endocytoscopy (EC) are applied clinically. The application of EC is intended to achieve the purpose of real-time histopathological endoscopic diagnosis without biopsy. Several studies have shown that EC is effective in identifying the nature of colorectal lesions and judging the depth of invasion in CRC. Based on the endoscopic diagnosis, the endoscopist can determine the treatment plan for the colorectal lesions. The latest EC is an integrated endoscope with a contact light microscopy system with a maximum magnification of 520 x. EC may demonstrate the atypical of gland structure and cells after staining (EC staining mode, along with the use of the EC-NBI mode. The endoscopic diagnosis of the EC staining mode is based on the EC classification (EC-C), used to predict the histopathological diagnosis of colorectal lesions. A prospective randomized trial showed that the diagnostic accuracy was 94.1% by EC-C. However, the diagnostic value of EC-C depends on the operator and may be influenced by the quality of the staining. Meanwhile, the high-quality staining process is time-consuming and tedious. Therefore, EC-NBI seems to be the first choice for EC diagnosis with the advantages of convenient operation and efficient diagnosis. EC-NBI can display the super-amplified surface microvessels of the lesion and provide pathological prediction according to the vessel classification (EC-V). EC-V achieved 99% diagnostic accuracy for hyperplastic polyps and 88.6% for invasive carcinoma. In EC examination, the investigators usually use EC-NBI and EC staining successively to diagnose colorectal lesions, which is believed to improve the diagnostic performance. However, the diagnostic value of increasing EC-staining after EC-NBI examination for predicting the pathological nature of colorectal lesions is still unclear. Therefore, this retrospective study aimed to evaluate the diagnostic value of two different modalities of cell endoscopy for colorectal lesions and to clarify whether additional EC staining after EC-NBI could improve the diagnostic performance of predicting the pathological diagnosis of colorectal lesions. In the study, the investigators collect clinical information of colorectal lesions which were diagnosed by endoscopic diagnosis (including EC-NBI and EC-staining) and pathological diagnosis. Then, the investigators calculate the accuracy, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and high confidence diagnosis rate of EC-C and EC-V classification, respectively. Inter-and intra-observer agreement in the diagnosis of EC-C and EC-V will be calculated.
NCT06971107
The goal of this prospective observational study is to learn more about how a specific type of DNA repair issue-called mismatch repair deficiency (dMMR)-affects colon cancer in people living in Turkey. The study will look at how often dMMR occurs, how it is reported, and how it relates to treatment outcomes. The main questions it aims to answer are: * How common is dMMR in colon cancer, and does it vary by where the tumor is in the colon? * How often is MSI (microsatellite instability) status reported in colon cancer biopsy reports before surgery? * How do different types of dMMR (such as MLH1/PMS2 loss, MSH2/MSH6 loss, or sporadic cases) affect survival over three years? Participants will: * Be people who had surgery for colon cancer between June 1, 2025 and May 31, 2026 at hospitals in Turkey that treat more than 30 colon cancer cases each year. * Have their medical and pathology data reviewed, including information about tumor location, biopsy results, surgery, and treatment. This study will not involve any new treatments. Instead, it will use existing medical records to better understand how to improve care and identify people who may benefit from immunotherapy. Results from this study will be shared at scientific meetings and published in medical journals.
NCT05534386

NCT05882175
Hemophagocytic lymphohistiocytosis (HLH) associated with hematologic malignancies (HM-HLH) is a syndrome with an abysmal prognosis (10-30% 5 years overall survival). The investigators have recently established an improved diagnostic and prognostic index for HM-HLH, termed the Optimized HLH Inflammatory (OHI) index. The OHI index is comprised of the combined elevation of soluble CD25 (sCD25) \> 3,900 U/mL and ferritin \>1,000 ng/mL . However, the true incidence and outcomes of HLH/OHI+ in an unselected cohort are unknown, and so is the mechanism of HM-HLH.
NCT06968702
The ICOPE Brazil study aims to understand aging trajectories in Brazil, especially healthy aging trends based on intrinsic capacity, a collective of mental and physical capacities one may have to maintain their functional ability to execute daily life activities. Tests and questionnaires will be applied to collect data on mobility capacity, cognitive capacity, nutritional status, vision, and hearing (sensorial) capacities, and mental health. These assessments are in consonance with what the World Health Organization proposed in the Integrated Care for Older People Program (ICOPE). Participants will be followed up for three years, and the primary outcomes of interest are loss of intrinsic capacity, mobility impairment, cognitive impairment, incident depressive symptoms, loss of functional ability, incident frailty, incident sarcopenia, incident falls, hospitalization, multimorbidity, and mortality.
NCT06968949
Schools are the most common venue for youth mental health services, but school mental health (SMH) typically does not use evidence-based clinical interventions (CI), common elements of effective mental health, or effective implementation strategies. To address this gap, a multidisciplinary team developed the Brief Intervention for School Clinicians (BRISC), a four-session engagement, brief intervention, and triage strategy targeting a range of mental health (e.g., anxiety, depression, past trauma) and other problems (academic, peer, family). BRISC outperformed SMH usual care on engagement, treatment completion, and youth self-reported problem severity. Although there are many evidence-based SMH strategies such as BRISC, integration into practice is poor because accompanying implementation strategies are often absent, poorly defined, or insufficiently tailored to the education context.

DECIDE- Deep phenotyping for clinical inferring response in treatment resistant depression -Study Building upon the "Biobanking" initiative at the Max Planck Institute of Psychiatry, the present project aims to identify clinically relevant subtypes of treatment-resistant depression (TRD) through Clinical Deep Phenotyping (CDP). According to clinical trials, 30-40% of the patients suffering from TRD benefit from lithium treatment. By collecting multimodal biological and clinical-diagnostic markers, such as structural and functional brain imaging via magnetic resonance imaging (MRI), brain signals from electroencephalography, comprehensive blood tests, assessment of perception and cognition through neuropsychological testing, as well as the evaluation of specific depression symptoms and psychological and other comorbidities using standardized questionnaires, a bio-clinical signature will be identified using multivariate machine learning algorithms as an integration method. This signature aims to predict the response to lithium therapy in TRD. Prospectively, such an algorithm could later personalize the treatment decision of 'lithium administration in TRD'. This concept is in line with the Research Domain Criteria (RDoC) of the National Institute of Mental Health (NIH) and aims to offer lithium therapy as a personalized treatment strategy for TRD. Specifically, this means that the likelihood of treatment response can be estimated before administration based on the results of the present study, thus enabling lithium to be offered specifically to those patients who are likely to benefit from it. The study design is non-interventional, meaning the decision for lithium treatment is made for patients according to clinical routine in accordance with the recommendation of the German National Treatment Guideline (NVL) independent of study enrollment. Study participation does not influence treatment decisions for the patients.
NCT06955962
This study is a randomized controlled, pre-test-post-test experimental research aimed at examining the effects of mandala art therapy on symptom severity and quality of life in individuals diagnosed with Multiple Sclerosis (MS). The main goal is to determine whether mandala art therapy helps reduce the frequency and severity of MS symptoms while improving participants' overall quality of life. It is expected that mandala art therapy will support MS patients in managing current and potential symptoms, coping more effectively with the disease, and improving adherence to treatment. As a result, a reduction in healthcare utilization, related costs, MS-related complications, and mortality is anticipated. The study will be conducted between May and August 2025 at the Neurology Outpatient Clinic of Karadeniz Technical University Practice and Research Center, involving 70 patients-35 in the intervention group receiving mandala art therapy and 35 in the control group receiving standard care.

NCT04606199
The aim of the Everyday Moments of Mindfulness (EMMI) study is to test whether brief mindfulness-based practices will improve daily psychological stress responses in women (age 30-60) who report a history of early life adversity. Following a baseline visit (remotely or in person), participants complete daily surveys and audio-guided mindfulness-based practices in everyday life via the study app. Specifically, participants receive app-notifications three times/day (morning, afternoon, evening) to complete daily surveys of current stressors and psychological states. At each notification, each participant is then randomly assigned to either receive a mindfulness-based intervention or not (max of 3 interventions/day). Thus, participants are randomized many times over the course of this 30-day study. At the end of the study, participants complete a follow-up visit (remotely or in person).

NCT06665568
With progression of cancer, patients and their caregivers experience challenging emotional distress, which can make them feel depressed and very anxious. Patients with advanced cancer often do not have long to live. However, most antidepressants take a long time to act and cause unwanted side effects. There is hence a need for a fast acting antidepressant with fewer unwanted side effects. Ketamine is an effective and fast acting antidepressant originating from pain treatment, which has few unwanted side effects. It can be taken by a patient as a nasal spray when it is needed. The idea of treating depression and anxiety in cancer patients in palliative care with ketamine nasal spray is new. How effective ketamine will be at reducing depression and anxiety in patients is unknown . It is also unknown whether this kind of treatment will be safe and practical for palliative care patients. This study aims to answer these questions. Patients will be treated with a low dose (5 mg) of ketamine nasal spray and then measure its effectiveness, practicality and safety. Questionnaires will be used to measure these outcomes. If treating depression and anxiety with ketamine nasal spray proves to be effective, practical and safe, then it could help to improve the quality of life for palliative care patients and reduce the burden of their caregivers.
