NCT03230916
This study aims to obtain plasma pharmacokinetic (PK) data and characterize the PK profile of imipenem (IMI), cilastatin (CIL), and relebactam (REL) following administration of a single intravenous (IV) dose of MK-7655A (a fixed ratio combination of imipenem/cilastatin/relebactam), hereafter referred to as IMI/REL.
NCT05415982
Many patients suffering from posttraumatic stress disorder (PTSD) are resistant to established treatment consisting of psychotherapy. Patients often go years with this debilitating disorder without experiencing sufficient improvement. Approximately 1/3 of patients will drop out of treatment because of psychological burden and overactivation. A novel ketogenic diet treatment could amend established treatment, and potentially upregulate the threshold for exciting neurons in dysfunctional brain regions, mediated through various mechanisms. This may reduce PTSD symptoms, and thus enabling patients to respond to psychological treatment without getting overactivated and unable to process trauma. The purpose of this study is to investigate whether it is possible to carry out a ketogenic diet therapy for patients with PTSD for four weeks.
NCT05310110
Laryngeal mask airway (LMA) is currently the most widely used supraglottic airway device with advantages of simple and fast placement, reduced anesthesia drug use, more stable hemodynamics, and less throat discomfort after anesthesia compared to endotracheal intubation. Some studies claimed the use of muscle relaxants or local anesthetics (sprays or lubricants containing local anesthetics) for the throat before LMA placement can reduce the dosage of induction agents and postoperative throat complications. In modern society, more and more elderly people undergo elective surgery with the need of general anesthesia. However, they are the more vulnerable population with tendency of greater hemodynamic changes with more induction agent usage. Propofol is one of the most used induction agents which may lead to a drop in blood pressure. The objective of this study is to observe whether the dose of propofol and the changes in hemodynamics can be reduced by using muscle relaxants or laryngeal local anesthetics in elderly who receiving general anesthesia with LMA insertion.

NCT05904353
This is a study to improve the collaboration between primary and secondary health care on the treatment of osteoporosis after a hip fracture. In Akershus University Hospital, patients 75 years or older with a hip fracture, are offered treatment with an infusion of zoledronic acid 5mg, combined with vitamin D and calcium supplements, to prevent new fractures. General practitioners (GPs) are requested to take care of the follow-up on this treatment with annual infusions of zoledronic acid for 3 years. In the opinion of the investigators, it is expedient, safe, and sensible for parts of the subsequent treatment to be provided by GPs. If hospitals take responsibility for initiating the treatment, the investigators believe that most of the subsequent monitoring and continuance of treatment can be conducted by the primary healthcare service. Despite this, the investigators suspect that many patients do not get their annual infusions of zoledronic acid after discharge from the hospital. This quality assurance study aims to test a new system where ambulant nurses from the hospital support the GP in treating osteoporosis with the administration of zoledronic acid in the following 3 years after femoral neck fractures. Through the project, the investigators will create procedures for the administration and follow-up of zoledronic acid fitted in the setting of the GP office. The design is a cluster randomized controlled study (RCT) where the regions are prospectively randomized to either intervention or control regions. Patients ≥ 75 years, which suffer a femoral neck fracture, are identified in our Department of Orthopedic Surgery, where they are provided the first infusion of zoledronic acid 5 mg and proposed participation in the study. Patients from the intervention regions will be followed by the protocol of ambulant nurse-assisted administration of zoledronic acid. Patients from the control regions are offered the usual care. Both patients from the control and intervention regions are asked to fill out a questionnaire after 1 year. The questionnaire will ask if the patient has got zoledronic acid as encouraged in the medical journal after discharge from the hospital. The primary study outcome is if the patients are offered treatment at a one-year follow-up or not. Sample size calculation estimates a total sample of 130 patients based on a minimal clinically important difference of 20% follow-up between the groups. Because of high mortality, the investigators estimate the need for 200 patients. The investigators hypothesize that the one-year follow-up is better in the intervention group than in the control group.

NCT06242782
Guided Bone Regeneration (GBR) is an invaluable and beneficial surgical technique adopted when there is the need to augment an alveolar atrophy. Strong clinical and histologic evidence exists on the effectiveness and predictability of GBR in bone augmentation of ridge deficiencies. On the other hand, it is well known that GBR remains a challenge as in the most extreme cases, it is considered a highly technique-sensitive surgical procedure. Whilst there are numerous reviews which report the average incidence of complications in GBR, there is still insufficient evidence and manuscripts reporting a direct correlation between a specific biomaterial (membrane or scaffold) and observed complications. Only one recent systematic review and meta-analysis focused on wound healing complications following GBR for ridge augmentation procedures. Authors explored the complication rate based on the membrane type and on the timing of the first sign of soft tissue complications following bone augmentation procedures. They reported a complication rate of 17% of the overall soft tissue complications, including membrane exposure, soft tissue dehiscence, and acute infection (abscess). This estimate is consistent with that reported (12%) in a more recent systematic appraisal of the evidence on all types of complications in GBR (3). However, when horizontal augmentation procedures were reviewed, a higher rate (21%) of complications was reported within the first 18 months of a GBR procedure. This estimate was inclusive of all possible biologic complications following GBR whilst the rate of membrane exposure was of 23%. Vertical bone augmentation represents one of the most challenging bone regenerative procedures in surgical dentistry. This is because of the inherent difficulties of the surgical procedure and the high risk of complications. The primary aim of this procedure is to recreate alveolar bone in a vertical direction (without the support of any pre-existing walls) and enable recreation of a more favourable anatomy for the restoration of the edentulous site. Evidence on a variety of treatment options has been produced over the last 15 years including distraction osteogenesis, onlay bone grafting, and vertical ridge augmentation (VRA). Systematic reviews evaluating the efficacy of different surgical procedures for VRA either in a staged or a simultaneous fashion, reported a range of vertical bone gain of 2-8 mm. This gain was gradually lost (1.27 to 2.0mm) between 1 to 7 years post-surgery and a wide range of complications (0- 45.5%) has been reported. The aim of this study is to assess and compare incidence of complications and percentage of vertical bone gain when using four different barrier membranes in combination with 50/50 autogenous and xenogenous bone material in VRA procedures. Secondary aims will be to evaluate and compare early and late soft tissue wound healing, gingival microvasculature and structure, patient reported outcomes and the prevalence of need for further bone augmentation and need for soft tissue grafting. Additionally, this study will also aim to assess and compare histomorphometry and histochemistry analyses of core biopsies obtained before implant placement between the four different barrier membranes.
NCT05705622
In this study, it is aimed to examine the effect of oral care training for oral mucositis, which will be given by the researcher to patients who have undergone bone marrow transplantation, on the incidence and severity of oral mucositis in patients. The aim of the study is to be carried out in a public and private hospital in Antalya province, in two different hospitals with a public and private status, and with a total of 60 patients, 30 of which are in the experimental group and 30 in the control group. In the study, "oral care training for oral mucositis" and "oral mucositis follow-up procedure" will be developed by the researcher for bone marrow transplant patients. Bone marrow transplant patients will be educated and followed up according to the follow-up procedure before starting the chemotherapy regimen treatments planned before the transplant.

NCT06241001
The primary objective within the current study is to compare the acute and chronic effects of eccentric training and IASTM on the dorsiflexion ROM. To reduce the risk of Achilles tendinopathy, stretching and eccentric (lengthening) exercises are postulated to improve ankle dorsiflexion. An eccentric exercise lengthens an active muscle while it is under load. Consequently, eccentric calf muscle exercises can also increase ankle dorsiflexion through an increase in calf muscle strength. For the above mentioned reasons, a combination of stretching exercises and eccentric (lengthening) exercises are suggested as preventive intervention to increase ankle dorsiflexion. The biggest goal of IASTM is to remove scar tissues and facilitate a return to normal function following soft tissue recovery. These Techniques, eccentric stretching and IASTM works towards bringing back the normal range of motion and strength, allowing individuals to regain mobility and return to their usual activities and we will find out the better option from these.

Myeloproliferative disorders (MPD) include chronic myeloid leukemia (CML) (Ph +) and essential thrombocythemia (ET), the polycythemia vera (PV), myelofibrosis (MF) called SMP Ph. CML is the ultimate model of carcinogenesis. SMP is a characterized by a malignant monoclonal proliferation of a pluripotent hematopoietic progenitor determined by the presence of a balanced translocation between chromosomes 9 and 22 (Ph chromosome) which leads to major changes of a large number of cell functions. Investigators now believe that within the bone marrow exist two types of "hematopoietic niches' niche osteoblastic / endosteal and vascular niche, controlling the maintenance and differentiation of hematopoietic stem cell pool. The endosteal niche, is a hypoxic region near the endosteal trabecular, which provides protection to deeply dormant stem cells. Data from the literature suggest that in the SMP, especially CML, the interaction of malignant stem cells with the microenvironment niche Endosteal could favor their survival and resistance to treatment. The therapeutic management of CML was upset by the use of tyrosine kinase inhibitors (TKIs). However, despite these advances, even in situations of undetectable residual disease, it has been observed relapses of the disease stopped TKI leaving suggest that there is a resistance of leukemic stem cell to TKI. Work in the group Bipoa "Bio Engineering and Pathophysiology Osteo-Articular" helped develop a 3D model of ex vivo bone formation, which can mimic the endosteal niche. the goal is to apply this model to the SMP of hematopoiesis by referring to normal hematopoiesis. it will be tested the hypothesis that the endosteal ex vivo recess of the 3D modeling allows to highlight a special interaction can promote the persistence of the leukemia stem cell despite the use of effective therapies.

Fatigue is among the most frequently reported sequelae in stroke survivors. For a specific stroke diagnosis, aneurysmal subarachnoid hemorrhage (aSAH), fatigue, in general, is reported to be present in 30 to 90% of the patients. It is the mental fatigue component that significantly contributes to difficulties that patients with aSAH face when returning to normal life. However, there is substantial variation in the reported incidence of mental fatigue (25%-60%), which may be attributed to several methodological factors, such as differences in the follow-up periods and instruments used. Consequently, a complete understanding of how mental fatigue influences long-term recovery remains elusive. This research project will contribute to new and important knowledge in long-term effects after SAH when it comes to mental fatigue. In this study patients surviving an SAH will be assessed for mental fatigue at 5 years after the insult. The patients have previously been assessed at 1 and 3 years. All patients have been treated at Sahlgrenska University Hospital during the acute phase after SAH. Follow-up is performed after 5 years after aSAH through a structured telephone interview, where patients are scored using the Glasgow Outcome Scale-Extended (GOSE) Additionally, the patients receive a self-assessment questionnaire, the Mental Fatigue Scale, Patients are reminded to return the questionnaires at three times. This study aims to determine the long-term prevalence, severity, and dynamics of mental fatigue at 1, 3, and 5 years after an aSAH. The study also aims to identify whether demographic characteristics and secondary complications or diagnoses after aSAH can be associated with an increased risk of developing mental fatigue or unfavourable outcome.
NCT06240234
The goal of this medtech clinical trial is to develop and evaluate a machine learning algoritm to predict low blood pressure episodes during major surgery. The main questions it aims to answer are: * Could a novel method for cardiac output estimation through alterations in carbon dioxide improve the performance of a blood pressure based algoritm in order to predict low blood pressure episodes during major abdominal surgery? * Will the predictive performance of the algoritm improve with the addition of other patient specific data? * Do the estimated cardiac output and central venous saturation by the novel method agree with our invasive arterial pressure method for cardiac output, and samples via a central venous line, respectively? 300 participants will be anesthetized with total intravenous anesthesia and ventilated with the novel carbon dioxide based method, and arterial and central venous blood gases will be taken regularly throughout the operation. All physiological data will be stored for later analyses and development of the algoritm by machine learning methods. No other invasive interventions will be performed outside our standard clinical peroperative protocol.
