Acute kidney injury (AKI) has been recognized as a typical post- operative complication among the children undergoing surgical repair of a congenital cardiac defect. It is associated with increased morbidity and mortality in the intensive care unit and a higher utilization of hospital resources. However, how to precisely identify those who have greater hazard to encounter postoperative AKI seems ambiguous.
Trauma triggers a tissue response involving the central nervous system, the hypothalamic-pituitary-adrenal axis and the immune system. There are many surgical and anesthetic factors that affect the response to trauma, and the control of the inflammatory factor is considered the most important. (KÜÇÜKEBE, O.B. ET AL, 2017). Dexmedetomidine is a specific α2-adrenergic agonist. By direct action on the sympathetic nervous system, α2-adrenergic agonists can exert beneficial effects on the immune system through neuroimmune interactions. Its administration can induce an anti-inflammatory response due to different central (increase parasympathetic tone, promoting control of the inflammatory condition) and peripheral effects (stimulating innate immunity). (MILLER, 2015). This study aims to evaluate the effect of dexmedetomidine administration in association with general anesthesia in a medium-sized surgical model, videolaparoscopic cholecystectomy.
Adolescents with mood disorders experiencing major depressive episode have poor efficacy of medication treatment. High-Definition Transcranial Direct Current Stimulation (HD-tDCS) has been proven adjuvant efficacy in patients with major depressive episode. However, the optimal evidence-based stimulation parameters have not been clearly defined, which greatly limits the efficacy of HD-tDCS in the treatment of major depressive episode.This trial will compare a novel form of accurate and personalized HD-tDCS treatment protocol guided by neuroimaging biomarkers to the routine stimulation(stimulation target is L-DLPFC, central electrode is anode).The personalized selection of stimulation site, central electrode polarity will be determined by neuroimaging biomarkers. The study aims to propose a novel personalized neuroimaging-guided HD-tDCS strategy, to evaluate the efficacy and safety of the treatment, further to understand the biological mechanism of the personalized HD-tDCS treatment.
The purpose of this study is to evaluate the effect of a 12 week digital treatment program for patients with hand osteoarthritis. The treatment consisted of exercises and educational sessions with respect to the disease, its natural course and recommended treatment strategies. Design: An observational longitudinal cohort study. The investigators will include participants who participated in the digital treatment of Joint Academy® for 3 months. Outcomes: Investigators will analyze pain with Numeric Rating Scale (NRS) 0-10 (best to worst), function with the Functional Index for Hand OsteoArthritis (FIHOA) and HRQL with EQ-5D-5L at baseline and at 3 months. Main outcome will be change in pain. The investigators will also analyze minimally clinical important changes (improved or not) and mean changes in EQ-5D-5L index score, pain and function.
Postoperative acute kidney injury is associated increased risk of morbidity and mortality. Older patients are at high risk of developing postoperative acute kidney injury. However, the incidence and associations of postoperative acute kidney injury in older patients are not well understood. This study aims to develop and validate a predictive nomogram for postoperative acute kidney injury in older patients undergoing noncardiac surgery.
the aim of this study was to evaluate the accuracy of the various virtual articulator mounting procedures.
Bacterial ecology of pilonidal cysts Single centre retrospective exploratory study of medical data contained in the medical records of patients operated on in the centre between 01/08/2020 and 30/11/2020.
Observational study on the treatment of pilonidal cyst with Holmium laser. Single-centre retrospective study of medical data from patients' medical records
The subject uses cytof to analyze PBMC of sporadic AD and DLB, which is used to reveal the differences in immune characteristics of the two diseases at the single-cell level, build immune models for specific diseases, and define these two neurodegenerative diseases with high precision from the level of molecular immunity. To provide basis for further study of the immunohistochemical differences between the two diseases, and provide objective support for clinical diagnosis and differential diagnosis.
The adaptive immune response plays an important role in myocardial healing and remodeling after acute myocardial infarction in patients. Therefore, the involved lymphocytes represent a novel target for therapeutic interventions. However, there are no established blood-derived biomarkers to predict the quantity and quality of the adaptive immune response to cardiac injury. Multimodal imaging of the heart and immunologic organs might provide such information. Recent retrospective analysis of patients after MI revealed enlarged mediastinal lymph nodes associated with increased CXCR4 radiotracer accumulation, thereby indicating that CXCR4 PET-based lymph node imaging provides a non-invasive quantitative readout of the local adaptive immune response. These considerations are further fuelled by the fact that, within lymph nodes, CXCR4 is expressed almost exclusively on lymphocytes, whereas various other cell types express CXCR4 within the myocardium. This leads to the hypothesis that the size of mediastinal lymph nodes and their respective CXCR4 PET signals correlate with the adaptive immune response to cardiac injury and might provide predictive information for functional cardiac decline during follow-up. This prospective clinical study will use multimodal imaging to monitor chemokine receptor 4 (CXCR4) expression in the lymph nodes, myocardium, spleen, and bone marrow after acute MI. The combination of cardiac magnetic resonance (CMR), echocardiography, and positron emission tomography (PET) along with blood collection for immunophenotyping will allow to determine i) if the size of mediastinal lymph nodes and their respective PET-derived CXCR4 signals at baseline correlate with the adaptive immune response to acute cardiac injury; and ii) if they predict cardiac adverse remodelling during longitudinal follow-up.
