NCT03441282
The concept of precision medicine - taking individual variability into account when planning preventions and interventions - is not new but is quickly gaining attention in this age of powerful methodology of patient characterization and development of tools to analyze large sets of data. Oncology is the most obvious field in which this information has been readily applied. Increasing focus, nationally and internationally, on developing broad databases of patient genetic information and research efforts evaluating those data will, hopefully, lead to the development and application of evidence-based data enhancing the practice of all fields of medicine. It has yet to become obvious how this information can best be applied to the field of anesthesiology. Most genomics work in anesthesia has been focused in the area of pain medicine. There is a known genetic influence on the potency of opioid-induced analgesia, however; a genetic component of opioid-induced respiratory depression has yet to be thoroughly evaluated. Respiratory depression plays a role in clinical care - from procedures requiring sedation with monitored anesthesia care to treating post-opertative pain and chronic pain - but perhaps its largest current role in the public arena is the unfortunate deaths caused by side effects due to drug overdose. Personalized medicine remains on the horizon for the field of anesthesia, but, as genetic testing becomes more affordable and mainstream in clinical practice, the potential applications are broad. Most readily would be its incorporation into development of patient specific pain regimens. Respiratory depression is a potentially lethal side effect of opioid therapy. In light of the opioid epidemic and CDC-scrutiny of opioid use, determining genetic profiles susceptible to respiratory depression could prove useful in further tailoring the treatment of pain both in the perioperative setting and in the chronic pain management setting.
NCT06115044
Overarching hypothesis In critically ill adults enteral feeding in a diurnal intermittent pattern improves patient centred outcomes. Research questions for this study Are the same derangements in metabolic and hormonal function observed in healthy volunteers when fed continuously via a nasogastric tube observed in critically ill patients and can those derangements be mitigated by intermittent diurnal feeding? Aim of this study Assess the effect of an enteral nutrition regimen mimicking the usual diurnal meal pattern on hormonal profile and metabolism in critically ill adults. This will generate novel and important proof of concept data and support progression to a clinical trial integrating investigation of physiological responses and patient centred outcomes. Objectives of this study Laboratory: Characterise patterns of hormone, lipid and metabolite response to intermittent diurnal feeding in critically ill adults. Clinical: assess feasibility, tolerability (vomiting and gastric residual volume) and efficacy (calorie delivery) of intermittent diurnal feeding in critically ill adults.
NCT06218030
The goal of this feasibility study is to determine the tolerability and safety of add on treatment with L-methylfolate in patients with treatment-resistant generalized anxiety disorder (GAD). The primary objective is to monitor for side effects and other risks associated with the treatment. Secondary objectives are to compare the severity of symptoms, serum levels of folate, vitamin B12, C-reactive protein, homocysteine, tumor necrosis factor alpha and interleukin 6 before and after treatment. Participants will continue with their usual treatment for GAD and receive add on treatment with L-methylfolate 15 mg per day for 8 weeks. All participants will receive the same intervention.
NCT06647394
To determine if application of Myriad Matrix to split thickness skin graft donor sites improves post-operative pain and appearance of the wound.
NCT02713386
This phase I/II trial studies the side effects and the best dose of ruxolitinib phosphate when given together with paclitaxel and carboplatin and to see how well they work in treating patients with stage III-IV epithelial ovarian, fallopian tube, or primary peritoneal cancer. Ruxolitinib phosphate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as paclitaxel and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving ruxolitinib phosphate together with paclitaxel and carboplatin may be a better treatment for epithelial ovarian, fallopian tube, or primary peritoneal cancer compared to paclitaxel and carboplatin alone.
NCT04155541
Secondary data collection study: safety and efficacy of VIZIMPRO under Japanese medical practice
NCT06919861
This clinical trial aims to compare the pharmacokinetic (PK), pharmacodynamic (PD) parameters, and safety between Nanokine of Nanogen Pharmaceutical Joint Stock Company and Eprex® of Janssen Cilag Ltd on healthy male volunteers. The biosimilarity of erythropoietin (EPO) between Nanokine (test) and Eprex® (comparator) was evaluated in a randomized, double-blind, two-sequence, crossover study. Subjects received a 4,000 IU subcutaneous dose of either formulation, followed by the alternate after a 28-day washout. Key pharmacokinetic (PK) parameters, Cmax and AUCinf, were assessed, with geometric mean ratios/GMR (90% CI) falling within the regulatory range (0.80-1.25). Pharmacodynamic (PD) markers (reticulocyte count, hematocrit, hemoglobin, and RBC count) need to show comparable effects. Safety evaluation (adverse events and serious adverse events, other safety assessments such as vital signs, testing, and examination) supports their interchangeability in clinical use.
NCT05036070
This study is a 12-month, prospective, 2-arm (1 test \& 1 control), randomized (1 test:1 control), bilateral, subject/evaluator-masked clinical investigation of the EPV IOL versus the standard TECNIS monofocal control IOL. The study will be conducted at a minimum of one to a maximum of five sites in France, with a total of 40 evaluable subjects for the investigational lens group and 40 evaluable subjects for the control lens group participating in the sub-study. The peripheral and functional testing will be conducted on a sub-group of subjects who achieve binocular uncorrected distance visual acuity (UCDVA) of 0.2 logMAR or better and/or are able to perform the driving simulator-sickness testing as determined by patient response to the SSQ (Appendix D) at the first 1-month visit. The eye implanted first will be considered the primary study eye (first eye). Subjects will be randomized to either the investigational IOL Model C0001 or the control IOL Model ZCB00 in both eyes.
NCT05090826
This is a prospective and retrospective, single-center, single-arm, open-label clinical study of the TECNIS Synergy™ IOL. The study will enroll up to 100 subjects from a single site in China. All implanted subjects will be followed for 12 months postoperatively.
NCT06987591
Aim of the study was to analyse data on cervical dilation and fetal descent patterns in low-risk women, who did or did not receive intermittent low-dose epidural analgesia (EA), and who had either a vaginal or a caesarean delivery. Therefore, we conducted a retrospective analysis, retrieving data from October 1st 2008 to October 31st 2018. We selected 6030 women categorized as Robson Group 1, divided into four groups according to the mode of delivery (vaginal or caesarean) and the presence of EA: * Vaginal delivery with EA (VD-e) * Vaginal delivery without EA (VD-n) * Caesarean delivery with EA (CD-e) * Caesarean delivery without EA (CD-n)
NCT02558972
Vasovagal syncope (VVS, simple faint) is the most common cause of transient loss of consciousness and represents the acute episodic form of orthostatic intolerance (OI). Postural tachycardia syndrome (POTS) is the common chronic form of OI. Both are defined by debilitating symptoms and signs while upright relieved by recumbency. Northera should therefore improve both sympathetic splanchnic arterial vasoconstriction and sympathetic splanchnic venoconstriction in POTS and VVS, and may represent an ideal drug to improve the orthostatic response in POTS and VVS.
NCT06403618
The goal of this observational study is to to evaluate the accuracy and sensitivity of PreCursor-M+ on a post-aliquot of liquid-based cytology (LBC) cervical samples (biopsy) obtained by physicians in a group of women with histologically-proven diagnoses of CIN2. The PreCursor-M+® assay is a multiplex real-time methylation specific PCR test that identifies the level of promotor methylation of the host cell genes FAM19A4 and miR124-2, known biomarkers associated with cervical carcinoma and transforming CIN in cervical cells. To evaluate the clinical course of CIN2 at 2 years after the first diagnosis, with an interval evaluation at 6 months. After enrolment, women will be divided into two groups: "active surveillance" and "immediate treatment". In the first group, clinical outcomes to be assessed, in relation to the PreCursor-M+ result at baseline, will include regression to \<CIN2, persistence of CIN2, and progression to CIN3+. In the second group, we will evaluate the histological diagnosis at cone specimen (downgrading or upgrading) and the 2-year cumulative incidence of CIN2+ recurrence based on the PreCursor-M+ result at baseline.

Randomized controlled trial for comparison of the hand dysfunction in coronary diagnosis and intervention via distal vs conventional radial access
NCT06175312
How does one know what to look at in a scene? Imagine a "Where's Waldo" game - it's challenging to find Waldo because there are many 'salient' locations in the picture, each vying for one's attention. One can only attend to a small location on the picture at a given moment, so to find Waldo, one needs to direct their attention to different locations. One prominent theory about how one accomplishes this claims that important locations are identified based on distinct feature types (for example, motion or color), with locations most unique compared to the background most likely to be attended. An important component of this theory is that individual feature dimensions (again, color or motion) are computed within their own 'feature maps', which are thought to be implemented in specific brain regions. However, whether and how specific brain regions contribute to these feature maps remains unknown. The goal of this study is to determine how brain regions that respond strongly to different feature types (color and motion) and which encode spatial locations of visual stimuli extract 'feature dimension maps' based on stimulus properties, including feature contrast. The investigators hypothesize that feature-selective brain regions act as neural feature dimension maps, and thus encode representations of salient location(s) based on their preferred feature dimension. The investigators will scan healthy human participants using functional MRI (fMRI) in a repeated-measures design while they view visual stimuli made salient based on different combinations of feature dimensions. The investigators will employ state-of-the-art multivariate analysis techniques that allow them to reconstruct an 'image' of the stimulus representation encoded by each brain region to dissect how neural tissue identifies salient locations. Each participant will perform a challenging task at the center of the screen to ensure they keep their eyes still and ignore the stimuli presented in the periphery, which are used to gauge how the visual system automatically extracts important locations without confounding factors like eye movements. Across trials and experiments the investigators will manipulate 1) the 'strength' of the salient locations based on how different the salient stimulus is compared to the background, 2) the number of salient locations, and 3) the feature value(s) used to make each location salient. Altogether, these manipulations will help the investigators fully understand these critical salience computations in the healthy human visual system.
NCT02842424
Peripheral artery disease (PAD) is a manifestation of atherosclerosis that produces progressive narrowing and occlusion of the arteries supplying the lower extremities. The most common clinical manifestation of PAD is claudication, i.e., a severe functional limitation identified as gait dysfunction and walking-induced leg muscle pain relieved by rest. The standard therapies for claudication include the medications cilostazol and pentoxifylline, supervised exercise therapy and operative revascularization. Recent data demonstrated that 24 weeks of treatment with the angiotensin-converting enzyme (ACE) inhibitor Ramipril produces improvements in the walking performance of patients with claudication that are higher than those of cilostazol and pentoxifylline and similar to those produced by supervised exercise therapy and operative revascularization. The mechanisms by which Ramipril therapy produces this impressive improvement in the functional capacity of claudicating patients remain unknown. The Investigators hypothesize that treatment of claudicating PAD patients with Ramipril will improve walking performance and quality of life by improving the myopathy of the gastrocnemius. Improved myopathy is a consequence of reduced oxidative damage, reduced TGF-β1 production by vascular smooth muscle cells and reduced collagen deposition in the affected gastrocnemius.
NCT02884180
Trial name: DEXRAR: Dexamethasone in revision arthroplasty: A randomised, blinded, 2-group clinical trial Trial acronym: DEXRAR Background: Effective postoperative pain management is essential for the well-being and rehabilitation of the surgical patient. No "gold standard" exists for pain treatment after revision total knee arthroplasty (TKA) and combinations of different medications are used with virtually no evidence for combined analgesic efficacy. Objectives: The objective is to investigate the analgesic effect and safety of dexamethasone as a single dose after revision-TKA in combination with paracetamol, ibuprofen and local infiltration analgesia Intervention: The patients are randomised into to groups: A) 24 mg dexamethasone i.v. B) isotonic saline i.v. Design and trial size: Placebo controlled, parallel 2-group trial with adequate centralised computer-generated allocation sequence and allocation concealment with block size of 12. Blinding of assessor, investigator, caregivers and patients. Sample size: 108 eligible patients are needed to detect a difference of 11,3 mg morphine for the first 24 h postoperatively with a standard deviation of 20 mg, a type 1 error rate of 0,05 and a type 2 error rate of 0,20.
NCT02471638
To assess the safety and performance of the PQ Bypass System to access, deliver guidewires and implant stent grafts for a percutaneous fem-pop bypass.
NCT03997864
This study plans to learn more about whether taking the medication, Prazosin, immediately and during the weeks immediately following a traumatic event can help to reduce the risk of developing posttraumatic stress disorder (PTSD). Early post traumatic event sleep disturbance predicts the later development of PTSD. Prazosin has shown some effectiveness in reducing trauma related nightmares and sleep disturbance. We hypothesize that regulating sleep immediately after a sexual assault will reduce PTSD and diminish symptoms.
NCT04222660
Peripheral neuropathy affects about 50% of the diabetic population and there is no treatment other than good blood glucose control, which is ineffective in subjects with type 2 diabetes. Part of the problem for the lack of an effective treatment is the inability to detect peripheral neuropathy in its early stage. The hypotheses to be addressed in the first phase of this study is that changes in cornea sensitivity (blinking and squinting) following addition of a hyperosmotic solution will provide a novel screening tool for early diagnosis of peripheral neuropathy. For the second phase of the study the investigators will examine the effect of fish oil treatment of diabetic subjects with neuropathy on corneal nerve density and sensitivity. Corneal nerves are the most highly innervated part of the human body with great sensitivity. The first phase will use this property and determine whether sensitivity is lost in diabetic patients with neuropathy. Preclinical studies have supported this hypothesis and now this will be tested in human subjects. Preclinical studies have also shown that treating diabetic rodents with fish oil improves nerve regeneration and outcome measures of peripheral in diabetic rodents. In the second phase the investigators will perform preliminary studies in human subjects with diabetic neuropathy and determine whether treating them with fish oil increases corneal nerve density and sensitivity.
