NCT06305416
Macular edema in diabetes, defined as retinal thickening within two disc diameters of the center of the macula, results from retinal microvascular changes that compromise the blood-retinal barrier, causing leakage of plasma constituents into the surrounding retina and consequently retinal edema. Thickening of the basement membrane and reduction in the number of pericytes are believed to lead to increased permeability and incompetence of the retinal vasculature. This compromise of the blood-retinal barrier leads to the leakage of plasma constituents into the surrounding retina with subsequent retinal edema. Hypoxia produced by this mechanism can also stimulate the production of vascular endothelial growth factor (VEGF). Vascular endothelial growth factor (VEGF) increases retinal vascular permeability, causes breakdown of the blood-retina barrier and results in retinal edema. Diabetic macular edema (DME) is the most common cause of visual reduction in patients with Diabetes Mellitus. The prevalence of DME globally is around 6.8 %. Diabetic Retinopathy (DR) is the most common microvascular complication of diabetes and the leading cause of blindness worldwide. DME is a complication of diabetic retinopathy that affects the macula, which is located at the center of the retina and responsible for central vision. Bangladesh is the 10th country in the world for the number of adults living with diabetes with some 7.1 million (5.3-12.0). In Bangladesh, it is therefore expected that diabetic secondary complications, like DR, will increase along with the rising trend of diabetes mellitus. The use of therapeutic monoclonal antibodies has revolutionized in the treatment of many diseases. In recent years, millions of patients have been successfully treated with these biological agents. Ranibizumab is one such therapeutic monoclonal antibody for intraocular use. Ranibizumab is a humanized, recombinant, immunoglobulin G1 monoclonal antibody fragment against vascular endothelial growth factor A (VEGF-A) and thus prevents choroidal neovascularization. The small size of ranibizumab allows for enhanced diffusion into the retina and choroid.
NCT07008222
This research study is being conducted to see if using buffered lidocaine for Nexplanon placement decreases pain associated with administering local anesthesia compared to unbuffered lidocaine, which is currently used in clinic. Lidocaine is used to stop pain in the nerve fibers in order to decrease pain at the time of the procedure. We want to find out if using buffered lidocaine will decrease discomfort at the time of receiving local anesthesia for Nexplanon insertion.

NCT07005258
Invasive candidiasis are the most common form of fungal infection in critically ill patients, particularly intra-abdominal candidiasis (IAC), which is associated with high morbidity and mortality. The current diagnostic gold standard relies on conventional fungal culture, which has a long turnaround time and may delay targeted antifungal therapy. Non-culture-based assays such as 1,3-β-D-glucan lack specificity for early and definitive diagnosis. Molecular diagnostics, including PCR, offer faster and more specific detection, but their clinical use remains limited. The CandID PLUS PCR assay targets major Candida species and has not yet been evaluated on peritoneal fluid. The CANDIDIAG study aims to assess the feasibility and diagnostic performance of the CandID PLUS PCR in detecting Candida spp. in peritoneal fluid from ICU patients with suspected IAC. This study constitutes a post-hoc analysis of the pBDG2 study (Prospective evaluation of the peritoneal 1.3 Beta-D-glucan for the diagnosis of intra-abdominal candidiasis in the critically ill patients) registered with the number NCT 03997929). Therefore, all patients have been already recruited. For the CANDIDIAG study, we will use the biological collection of peritoneal fluid issue from the pBDG2 study. All patients with confirmed intra-abdominal candidiasis are identified. We will test de CandID PCR, retrospectively, on their peritoneal fluid and compared the results with the fungal culture.
NCT01754610
Strengthening Families Coping Resources (SFCR) Open Trials completes the second stage of the National Institute on Drug Abuse's intervention development model by testing a new family, skills-based intervention involving pre-post evaluation of families participating in multi-family groups. The purpose of this study is to gather practice-based evidence on the effectiveness of the manualized treatment, on the dynamics involved in the group format, and on implementation fidelity and feasibility. Analyses will involve initial exploration of the following hypotheses: 1) Families will show a significant increase in the constructive use of family coping skills and in general family functioning. 2) The target child will show a reduction in trauma-related symptoms and behavior problems. 3) Parents will show significant reductions in traumatic stress and other symptoms of distress. 4) Families will engage and participate in the treatment. 5) Providers will implement SFCR with fidelity. Other outcomes of interest are the process measures that will be collected to monitor participation in the groups, cultural sensitivity and acceptability, clinician competence, and intervention integrity.

NCT05864326
This study is a single-center, randomized, two-arm, controlled trial, including women requiring cervical ripening during the process Induction of Labor using Balloon catheter (BC). The primary objective of the study is to determine if the use of heated saline in the BC used for cervical ripening reduces the length of BC duration. Participants will be allocated to : * Intervention or warm group: the BC will be filled with heated saline water up to 40° C * Standard or room temperature group: the BC will be filled with saline water at room temperature.
NCT01793610
The goal of this clinical trial is to learn if MDMA in combination with therapy is safe and effective in people with chronic, treatment-resistant PTSD. The main questions it aims to answer are: * Does MDMA-assisted therapy reduce PTSD symptoms? * Is there a difference in PTSD symptoms between the 40 mg, 100 mg, and 125 mg groups? Researchers will compare two active doses (100 mg and 125 mg) of MDMA-assisted therapy versus a comparator dose of 40 mg MDMA-assisted therapy to determine if there is a reduction in PTSD symptoms. Participants will undergo three non-drug preparatory sessions, three MDMA-assisted therapy sessions and three non-drug integrative therapy sessions after each MDMA-assisted therapy session.
NCT07007416
This prospective observational study aimed to evaluate the effects of supraphysiological estradiol (E2) levels, induced by gonadotropin therapy during IVF, on cardiac electrophysiological parameters. Sixty-two women aged 18-40 undergoing IVF treatment at Konya City Hospital between December 2024 and January 2025 were included. ECG recordings were performed twice: once before gonadotropin stimulation and again on the day of hCG administration, when peak E2 levels were expected. Routine blood tests and hormone levels were also evaluated. Patients with obesity, cardiovascular disease, chronic illness, or medication use were excluded. After treatment, significant increases were observed in PR interval, J-Tpeak, QTc, and Tp-e values. E2 changes showed a moderate negative correlation with QTc and a low positive correlation with J-Tpeak. The results suggest that elevated E2 levels during IVF may affect cardiac electrophysiology, highlighting the need for careful monitoring in women with cardiac risk factors.
NCT03172195
Flare-up of ulcerative colitis (UC) is characterized by the inflammation of colon mucosa that requires the use of immunosuppressive therapies. In previous studies, the active role of cytomegalovirus (CMV) has been demonstrated, with a correlation between the cytomegalovirus DNA ((deoxyribonucleic acid) load in the inflamed tissue and the resistance to successive lines of immunosuppressive therapy (Roblin et al., Am J Gastroenterol 2011). The main aim of this monocentric prospective study is to evaluate the DNA viral load by qPCR (Polymerase Chain Reaction) of 3 herpesviruses (Epstein-Barr virus, herpes virus 6 and herpes simplex) together with that of CMV in colonic mucosa depending of the local inflammation (endoscopically normal region, inflamed mucosa or ulcer) in patients suffering of moderate to severe UC flare-up (Mayo score \>6 with endoscopic score higher or equal than 2). The viral load will also be correlated to the Mayo endoscopic score and the response to immunosuppressive drugs (steroid and anti-TNF (Tumor Necrosis Factor) monoclonal antibodies).
NCT06579027
The purpose of this study is to assess the feasibility and utility of 2 types of play-based training programs co-delivered by researchers and caregivers within home/community settings to promote arm function among 3-to-8-year-old children with hemiplegia. Specifically, investigators will assess the feasibility of implementation and acceptance/satisfaction associated with a researcher-caregiver co-delivered community-based training program involving either joystick-operated powered ride-on toys (SPEED training) or creative upper extremity training (CRAFT training). The investigators will also compare the effects of these 2 types of training programs on children's arm motor function and spontaneous use of their affected arm during daily activities.
NCT03328078
This is a multi-center, open-label study to evaluate the safety, pharmacokinetics (PK), and anti-cancer activity of oral administration of emavusertib alone or in combination with ibrutinib in adult participants with relapsed or refractory (R/R) hematologic malignancies. This trial will be completed in four parts. In Part A1, emavusertib will be evaluated first in a dose escalating monotherapy setting to establish the safety and tolerability (complete). In Part A2, emavusertib will be evaluated in combination with ibrutinib at 560 milligrams (mg) once daily (QD) or 420 mg QD as indicated by disease (Part A2 complete). Part B will comprise 2 cohorts to assess safety and efficacy of emavusertib in combination with ibrutinib in participants with R/R primary central nervous system lymphoma (PCNSL) who have directly progressed on a bruton tyrosine kinase inhibitor (BTKi). In this part of the study, emavusertib will be dosed at 100 mg or 200 mg twice daily (BID) in combination with ibrutinib in 28-day treatment cycles. Part C will comprise 3 treatment arms in the second-line setting to assess the efficacy and safety of emavusertib monotherapy, ibrutinib monotherapy, and emavusertib in combination with ibrutinib in participants with R/R PCNSL who are naïve to BTKi treatment. In this part of the study, eligible second-line participants with R/R PCNSL who are naïve to BTKi treatment will be randomized 1:1:1 to 1 of 3 treatment arms: (1) emavusertib 200 mg BID, (2) ibrutinib 560 mg QD, or (3) emavusertib 200 mg BID in combination with ibrutinib 560 mg QD.

Dislocated femoral neck fractures are routinely treated with cemented hemiartroplasty and the direct lateral approach (Hardinge) has commonly been used in Norway. The investigators have lately witnessed a significant change in the prefered surgical approaches in total hip arthroplasty (THA) in favor of the posterior and anterior approaches. The direct lateral approach has in THA, more or less, been abandoned in Norway. Numerous studies have reported superior results using the posterior and anterior approahes compared to the lateral approach.
