Surgery is a common treatment type for damaged joints, tendons and nerves in the upper limb where conservative measures are inappropriate or have failed. These conditions are common and result in significant levels of pain and functional disability. The investigators are conducting a broad ranging study of variation in the provision of surgical treatment and factors affecting outcomes after surgical treatment of upper limb conditions. This will be a population-based study of all patients undergoing surgical treatment funded by the National Health Service (NHS) of England over a nineteen-year period. This study will help to understand the factors associated with a poor outcome following surgery, which can be shared with patients considering treatment options. The investigators will also document current and future health service burden associated with commonly performed surgical procedures including complications and repeat operations.
This study will investigate whether seven days administration of the serotonin receptor subtype 4 (5-HT4) partial agonist prucalopride has effects on emotional processing and neural activity in healthy volunteers, compared to placebo administration. Using an experimental medicine approach, the effects of prucalopride on cognitive biomarkers of antidepressant action will be characterised. In a double-blind design, participants will be randomised to receive seven days administration of either prucalopride (1mg daily) or placebo. All participants will come for a Screening visit, Research Visit One (including an MRI scan) and Research Visit Two (including measures of emotional processing and non-emotional cognition). The primary study hypothesis is that seven-day prucalopride administration will have positive effects on emotional processing and reward sensitivity. A secondary hypothesis is that seven-day prucalopride administration will alter non-emotional cognition. Finally, the study will test the hypothesis that seven day prucalopride administration will alter neural activity during an emotional faces task and a memory task.
Hereditary hemorrhagic telangiectasia (HHT) results from genetic deregulation of angiogenesis. It is characterized by mucocutaneous telangiectasia responsible for recurrent epistaxis affecting quality of life (anaemia, iron deficiency, social distress). More rarely, HHT is complicated by the appearance of pulmonary, hepatic or cerebral arteriovenous malformations that can lead to serious complications: cerebrovascular accidents, cerebral abscesses, high output heart failure, and massive hemoptysis (1). The intensity of symptoms increases with age but with significant individual variability, even for the same mutation in the same family. Thus, while the mutations responsible for the disease have been identified, the pathophysiology is not fully understood because these mutations do not explain the great diversity of clinical presentations. Other factors not yet identified probably play an important role. Angiogenic T cells (TANG) are a newly individualized T cell population, defined by a CD4+CXCR4+CD31+ phenotype, which plays a key role in differentiating endothelial progenitors (2). In an earlier study, the investigators showed that patients with HHT had a decrease in CD4+ and CD8+ LT compared to a cohort of healthy subjects (3). They hypothesize that the lymphopenia mainly involves TANG, whose quantification could make it possible to assess the individual level of angiogenesis during HHT. The evaluation of the TANG levels could thus make it possible to personalize HHT management.
This survey will assess discrepancies between official clinical genetics guidelines and practices within 3 West regions of France.
Although there are many studies in the literature concerning methods of bonding of mandibular retainers whether directly or indirectly, there is a very limited evidence regarding their chair side time and bond failure. Also there are scarce data on fixed mandibular retainers bonded using 3D printed positioning tray.Thus, conducting a well-designed randomized clinical trial evaluating the chair side time and bond failure of 3d printed positioning tray and direct bonding method of fixed mandibular retainer.Null hypothesis is thatThe time needed for direct indirect bonding using 3D digital positioning tray of a mandibular fixed retainer is shorter than the time needed for direct bonding, and there is no difference in failures between the 2 bonding methods
The goal of this research study is to determine if the utilization of brief motivational interviewing (BMI) during continuous care is superior compared to traditional oral hygiene instruction (OHI) to reduce patients' plaque score, bleeding on probing (BOP), and gingival index (GI) longitudinal. An additional goal is to investigate chairside time of implementing BMI.
Patients with kidney cancer often undergo hand-assisted laparoscopic nephrectomy or Robot assisted partiel nephrectomy. The investigators performed a one-year retrospective study. the sudy revealed that 67% of the patients needed substantial amounts of opioids for postoperative pain management (PPM) in recovery despite a multimodal analgesic regime. In a prospective pilot study including ten laparoscopic hand-assisted nephrectomy, with severe postoperative pain the investigators found that bilateral Ultrasound-guided (USG) transmuscular quadratus lumborum (TQL) block substantially reduced pain and opioid consumption. This study aims to evaluate the effect on PPM of a bilateral USG TQL block compared to placebo.
Brief Summary: This study is a prospective, multicenter, randomized, controlled trial aimed to compare the reperfusion strategy and clinical outcomes of STEMI patients treated by angiography-guided vs. OCT-guided PCI. Patients presenting STEMI with coronary artery diameter stenosis ≤70% and TIMI blood flow grade 3 at index or after thrombus aspiration are randomly assigned to either an OCT-guided group or an angiography-guided group. In OCT-guided group, stent implantation or conservative medical treatment is determined based on OCT findings. Conservative non-stenting strategy will be recommended in those with culprit plaque erosions, certain ruptures without dissection and hematoma, SCAD without obstructive stenosis. In the angiography-guided group, reperfusion strategy is decided by the operators according to the local practice. The rate of stenting during primary PCI and clinical outcomes at 1-month and 1-year are collected.
