NCT06781346
Postoperative pain is a significant problem following breast surgery . If not treated in time, it may lead to delayed wound healing, respiratory depression, hemodynamic disorders, anxiety,other complications, and finally lead to difficult recovery of patients . Therefore, the prevention of postoperative pain is of great importance for patients. Opioids, while effective in pain management, are linked to a spectrum of adverse effects, including respiratory depression, post-operative nausea and vomiting, pruritus and constipation. The adoption of multimodal analgesia following breast cancer surgery emerges as a pivotal strategy to mitigate the complications associated with opioid use in the postoperative period.\[4\] US-guided rhomboid intercostal block (US-RIB) is a new fascial block technique discovered by Elsharkawy et al in 2016. Injection of local anaesthetic into the fascial plane between rhomboid major and intercostal muscles provided analgesia for both the anterior and posterior hemithorax,targets the lateral cutaneous branches of the ventral rami of the thoracic intercostal nerves from T2 to T9. Some clinical studies have reported that RIB can effectively reduce postoperative pain, reduce opioid consumption and improve the quality of recovery in patients with breast cancer surgeries . The ultrasound guided Thoracic paravertebral (TPV) block in the context of breast cancer surgery has been reported to decrease postoperative pain score up to 72 hours, reduce opioid consumption, improve the quality of recovery, and suppress the development or decrease the severity of chronic pain by anesthetizing the spinal nerves as they emerge from the intervertebral foramina, producing ipsilateral somatosensory, visceral and sympathetic nerve blockade. TPV block involves the injection of local anesthetic (LA) into the wedge-shaped paravertebral space deep to the superior costotransverse ligament (SCTL). In our study investigators hypothesized that the Rhomboid Intercostal block (RIB) can provide an effective analgesia comparable with thoracic paravertebral (TPV) block without the necessity to approach the pleura and the attendant risks in adult patients undergoing Breast cancer surgeries.

This study evaluates if it is possible to identify quantitative parameters from audio signals to describe the changes in patient's state in relation to frailty and distress.
NCT06779877
Percutaneous dilatational tracheostomy (PDT) is a common bedside alternative to surgical tracheostomy in intensive care unit patients. Intracranial pressure measurement is a vital parameter that should be monitored when performing any procedure including PDT in these patients. During PDT, changes in intracranial pressure may occur depending on the position applied, hypercarbia and hypertension that may develop during the procedure. However, the effect of PDT procedure on intracranial pressure is controversial. It is imperative to ascertain the impact of PDT on intracranial pressure, along with the factors that influence its fluctuations during the procedure. This is of particular significance in order to avert the occurrence of deleterious conditions that may be engendered by elevated intracranial pressure. The aim of current study was to evaluate the effect of PDT procedure on intracranial pressure.
NCT06776471
It is planned to include girls and boys between the ages of 6-12 who apply to Başkent University Faculty of Dentistry, Pediatric Dentistry Clinic for routine dental examination. Informed and written consent will be obtained from the parents of each participating child. In teeth planned to undergo treatment, molar ıncisor hypomineralization diagnosis will be made primarily in the presence of limited opacities/enamel fracture after eruption in at least one first permanent molar according to European Academy of Paediatric Dentistry criteria. In teeth diagnosed with molar ıncisor hypominerlization, tooth surfaces will be cleaned with a slow-speed rotary brush and dried with air before the evaluations to be made using the ICDAS II index. Early enamel caries lesions will be assessed by visual examination. The decayed, missing, filled teeth of the patients will be assessed according to the World Health Organization assessment criteria. The groups will be double-blind randomized as conventional fissure sealant (n=63) and self-adhesive flowable composite (n=63): Group I (acid+resin-based fissure sealant) will be etched with 37% phosphoric acid for 30 seconds, the surface will be rinsed and air dried until an opaque appearance is achieved on the enamel. Low-viscosity fluoride containing resin based fissure sealant will be applied to the etched enamel surface. Group II (self-adhesive flowable composite); self adhesive flowable composite will be applied in one step. All applied fissure sealants will be polymerized using a light device. Finally, occlusion control will be performed on fissure sealants with articulation paper.The Schiff Cold Air Sensitivity Scale will be used to assess the presence of hypersensitivity in the affected teeth by applying the air-water spray perpendicular to the occlusal surface of the tooth from a distance of 1 cm for 1 second. Clinical evaluation of fissure sealants will be performed at 1, 3, 6 and 12 months using modified . Sealants that receive "Alpha" or "Bravo" scores for all criteria (anatomical form, marginal adaptation, surface texture, marginal color change, retention and secondary caries) will be classified as successful; while "Charlie" scores received from one or more of the United States Public Health Service criteria will be evaluated as failure.
NCT05535816
The purpose of this study is to assess the accuracy of ultrasound and traditional fluoroscopy to find the residual fragments before retrograde intrarenal surgery is complete. This would ultimately limit the need for radiation exposure and improve the quality of clinical care given to patients and healthcare teams.
NCT06781242
Genotype-phenotype relationship between adult cryptogenic cholestasis and mutations in genes responsible for progressive familial intrahepatic cholestasis
NCT05547750
Nocturnal leg cramps (NLCs) are sudden contractions of the leg muscles, usually in the posterior calf muscles at night, affecting sleep quality. Because the precise pathophysiology of NCLs is unclear, different interventions have been proposed. There is conflicting evidence regarding the efficacy of conventional interventions in preventing cramps. Thus, the present study aims to investigate the effects of vitamin K2 for NLCs in a prospective randomized, double-blind, controlled trial.

NCT06781216
Cancer is still the second leading cause of death worldwide with approximately 9.6 million deaths per year. Gynecological cancers, which are the most common type of cancer among women, significantly affect the quality of life by disrupting the functions of the reproductive system of women. Endometrial cancer has an important place due to its prevalence in our country and worldwide. Although stress factors related to endometrial cancer may continue after the completion of treatment, this situation has the potential to negatively affect the psychological and physiological health of women. This research is a randomized controlled trial aiming to evaluate the effect of motivational interviewing applied to women who completed endometrial cancer treatment and were followed up in the outpatient clinic on post-traumatic stress symptoms and post-traumatic growth. Simple randomization method will be used in the study. The sample size to be included in the study was determined as 66 participants in total, 33 in the intervention group and 33 in the control group. In the study, the effectiveness of motivational interviewing technique application in women with endometrial cancer will be evaluated based on evidence using Post-Traumatic Stress Disorder Checklist for DSM-5, Post-Traumatic Growth Scale and Ways of Coping Scale. Research data will be collected from women who meet the inclusion criteria at Akdeniz University Hospital Gynecology and Obstetrics Clinic between January 2 and August 31, 2025. The motivational interviews planned to be implemented as an intervention method in the research aim to reduce post-traumatic stress symptoms, develop coping strategies and increase the level of post-traumatic growth in women with endometrial cancer.
NCT06642428
This randomized controlled Phase III trial was designed to evaluate the impact of supplemental vitamin D (VD) on the efficacy and side effects of neoadjuvant therapy in patients with breast cancer.
NCT06782230
Rare diseases (RDs) have been defined by the European Union (EU) as life-threatening or chronically debilitating conditions affecting less than 1 person in 2000. RDs are complex and often need special treatments, thus combined efforts are required to address them to improve diagnosis, care and prevention. To date, over 6.000 RDs are known and most of them are \"orphans\". They do not have a market large enough to gather support to sustain research and discover treatments. Most RDs are disabling, incurable, painful and cause great suffering. Their complexity and heterogeneity often make diagnosis difficult; 25% of RD patients experience a diagnostic delay of 5 to 30 years and this has important implications for patient care. Thus, new diagnostic and therapeutic strategies are urgently needed. RDs registries are increasingly recognized as an effective tool to advance RD research. They are necessary to bring together patients and to pool data to achieve a sufficient sample size to facilitate epidemiological and/or clinical research. It is well known that registries are more effective when annexed to biobank infrastructure since make an important contribution to identify and validate biomarkers, uncover novel genes, elucidate pathogenesis at the Omics level, and develop new therapeutic strategies. Biobanks serve as biological samples and related clinical data repositories from affected patients and from undiagnosed patients experiencing with the \"diagnostic odyssey\", with the view of a retrospective diagnosis. The aim of creating a biobank is to make available a significant number of well-characterized and properly preserved samples and related data, to the scientific community for large-scale studies. Indeed, the recent advances in the technology of molecular biology and genetics require a large number of properly preserved biospecimens. This is certainly facilitated by building biobank networks. To this regard, in Italy, the collection of RDs samples is fragmented. The existing RD biobanks are of small or medium-size. They are stand-alone collections since only a limited networking among these infrastructures has been organized up to now. The objectives of this project will be: Aim 1: Establishment of the Scattered RD Biobank as a network of RD biobanks in order to overcome RD biological sample scarcity and to collect samples and data of high quality available to the scientific community for future collaborative studies in national and international co-operations Aim 2: Harmonization, Standardization and Network Governance. According to the document ISO 20387 illustrating the general requirements for biobanking, Standard Operating Procedures (SOPs) will be defined to ensure that every biobank in the network strictly follows the entire processes of collection, preparation, storage and distribution of biological material as well as related information and data. Common data bases and ethical/legal documents will be also generated. Aim 3: RD biobank upgrading and creation of novel RD biobanks. Already existing RD biobanks will be implemented in terms of organization of the sample collections according to the common SOPs and of extension of the sample collections and novel RD biobanks will be created such as Huntington\'s disease (OU3 and OU4), Marfan Syndrome, Hereditary Angioedema and Congenital Heart Diseases (OU1) biobanks. All the OU participating to this project are Reference Centre or Biological Research Centre (BRC) for RDs.
NCT06780683
Inflammatory Bowel Disease (IBD), which encompasses ulcerative Colitis (UC) and Crohn's Disease (CD), has seen significant improvements in patient outcomes with biologic treatments. However, nearly half of the patients are either primary or secondary non-responders to the existing biologics. Upadacitinib is the only oral small molecule targeted drug approved for IBD in China. There is a paucity of research on the efficacy and safety of upadacitinib in treating Chinese patients with UC and CD, and a lack of study data on the Chinese IBD population. This study aims to conduct a multicenter, single-arm, prospective, observational real-world study to analyze the efficacy and safety of upadacitinib in the treatment of Chinese patients with IBD, providing a basis for clinical decision-making.
NCT06772974
Nausea and vomiting are common GI symptoms of pregnancy. Multiple managing options have been used for NVP. Doxylamine succinate is used as first line treatment for NVP despite that alternative modalities such as ginger extracts and tablets is being explored. This RCT will be conducted after taking ethical approval and informed consent, in Department of Gynecology, Aziz Bhatti Shaheed teaching hospital, Gujrat. Patients will be divided into two equal groups. One group will receive tablet ginger while other group will receive Doxylamine succinate tablets. Baseline PUQE score (3- 15 point scale) over 24 hour will be noted according to symptoms of nausea and vomiting following 7 days of treatment and then at 2nd and 3rd week. Comparison of the change in the severity of nausea from baseline scores (Post-therapy PUQE score - base line scores) in both groups will be considered for results.

NCT06779370
Calcium hydroxide is generally preferred in endodontics as an intracanal medicament due to its antimicrobial and biological effects. However, the antimicrobial effect of calcium hydroxide is limited. A new calcium silicate-based root canal medicament has been developed as an alternative to calcium hydroxide-based medicaments. The aim of this study was to investigate the effects of calcium silicate-based root canal medicament on antibacterial, antifungal activity, and postoperative pain in root canal-treated teeth with periapical lesions.
NCT05130476
The parathyroid glands and their blood vessels are notoriously difficult to visualize and may therefore be unintentionally and irrevocably damaged during thyroid surgery. This project investigates new surgeon-performed imaging techniques that visualize the parathyroid glands and their vessels in real-time during thyroid surgery. The purpose is to examine, in a matched cohort study, whether the implementation of near-infrared-induced autofluorescence for identification of the parathyroid glands, combined with indocyanine green near-infrared angiography of the parathyroid feeding vessels, can reduce the incidence of postoperative hypocalcaemia in patients undergoing total and completion thyroidectomy at Odense University Hospital.
NCT06779240
Vertebral deformities, such as scoliosis, can have a significant impact on the physical and psychological health of patients. Over time, specific tools have been developed to investigate the extent of this impact; the SRS-22 (Scoliosis Research Society) questionnaire is the most commonly used instrument for assessing quality of life (QoL) in patients with idiopathic scoliosis. The Oswestry Disability Index (ODI), on the other hand, was developed to evaluate the quality of life in adult patients with chronic non-specific low back pain. The clinical protocols at our institute involve the regular and continuous evaluation of the quality of life in patients undergoing treatment and monitoring for scoliosis and other vertebral deformities. To this end, the SRS-22 questionnaire and the ODI questionnaire are employed, along with other measures such as the COMI (Core Outcome Measure Index) and ISYQoL (Italian Spine Youth Quality of Life). The aim of this study is to compare the properties of the ODI with those of the SRS-22 questionnaire in adults, by analyzing differences between individuals with non-specific low back pain and those with scoliosis. The secondary objective involves a sub-analysis based on the severity of scoliosis, dividing curves into major (30° Cobb or higher) and minor (below 30° Cobb). Finally, if sufficient data are available, the study will also evaluate other commonly used questionnaires (COMI and ISYQoL).
NCT03967795
The French intensive care societies (SRLF and SFAR), in agreement with the European and American societies for enteral and parenteral nutrition, recommend to quickly administer an artificial nutrition to patients admitted to ICU and for which it is expected that they will not be able to eat normally in the three days of admission. Enteral nutrition should be used in priority if the gut is functioning. However, intolerance to enteral nutrition, such as vomiting, regurgitation, increased residual gastric volume, or diarrhea, occurs in 40% of patients hospitalized in ICU receiving enteral nutrition. Intolerance to enteral nutrition leads to the risk of not receiving enough nutrition. Feeding intolerance also exposes to the risk of acute mesenteric ischemia, especially in the most severe patients under catecholamine for shock. Currently, it is not possible to predict intolerance to enteral nutrition in ICU patients. Thus, the diagnosis of intolerance is made a posteriori while enteral nutrition is in progress. Citrullinemia (normal concentration of 20 to 60 μmol / L), could be a good biomarker of the function of enterocytes involved in the absorption of food. The aim of this study is to evaluate the interest of citrullinemia to predict tolerance to enteral nutrition in ICU patients.
