Positive intra-thoracic pressures induced by mechanical ventilation can negatively impact right heart hemodynamics by restricting systemic venous return and increasing right ventricular afterload. These consequences may be detrimental in patients with a restrictive right ventricular physiology and in patients with single ventricle physiology. NAVA (Neurally Adjusted Ventilatory Assist) ventilation decreases intra thoracic pressures compared to conventional ventilation modes. Brain perfusion is both a hemodynamic indicator and a prognostic factor in cardiac postoperative care. Diffuse Correlation Spectroscopy (DCS) coupled with Near Infrared Spectroscopy (NIRS) is a new technology that allows monitoring, in addition to brain tissue oxygenation, changes in brain blood flow. This physiological study aims to evaluate the impact of NAVA mode ventilation on cerebral and systemic hemodynamics in post-operative cardiac surgery patients with preload dependant right ventricle or with passive venous return to the lungs . This prospective cross-over study will include 30 patients. Once stabilized in intensive care, patients will undergo 2 periods of ventilation in NAVA mode and conventional mode separated by a 30-minute washout period, in a random order. For each period the following information will be collected: changes in cerebral blood flow and cerebral oxygenation, hemodynamic parameters including cardiac output and oxygen transport and ventilatory parameters.
This study is a multi-center, prospective, registry study. This research was supported by the National Key Research and Development Program. They were divided into experimental group and control group according to whether the treatment plan was formulated by a multidisciplinary team. Patients of experimental group is strictly in accordance with standardized multi-disciplinary treatment protocols and meet the following criteria: 1. A multi-disciplinary conference discussion; 2. Detailed preoperative evaluation based on CT, MRI, fMRI and DSA. 3. Treatment modalities meet the following treatment criteria（craniotomy, embolization and stereotactic radiosurgery）. The control group was patients who had not been treated according to a multi-disciplinary treatment protocol. Patient baseline data, AVM angioarchitectural features, imaging DICOM data, surgical information, and follow-up information were registered. All patients were evaluated for neurofunction at baseline, 3 months, 12 months, and 3 years after treatment. Main observation endpoints: 1. Modified Rankin Scale; 2. Obliteration rate; 3. Subsequent hemorrhage; 4. Complication rate (such as morbidity rate, new-onset neurological dysfunction, and radiation-related complications). Secondary observation endpoint: improvement of clinical symptoms (epilepsy, headache, neurological dysfunction) at 3 months, 12 months, and 3 years after treatment.
This study is designed as a randomized, placebo-controlled, double-blinded, clinical trial with two parallel groups. This study investigates the association between a single dose of the drug, Clonidine, and the total amount of opioid administered under and 24 hours after surgery in children undergoing orthopedic limb surgery with the use of tourniquet. The investigators hypothesize that administration of clonidine to children undergoing limb surgery with the use of inflatable tourniquets would reduce post-procedural pain. This study is a pilot to obtain an effect size. Based on this the investigators will calculate a sample size for the main trial enabling us to reach a power of 0.8 with a significans level of 0.05.
This is primarily a feasibility study to determine whether quantitative measurement of volatile organic compounds (VOCs) in the breath of parturients undergoing labor is possible. Aim A: To determine baseline values of breath metabolites and volatile organic compounds (VOCs) in the breath for term pregnant women. Aim B: To gather preliminary data to determine breath metabolite and volatile organic compound (VOCs) signature change during labor and delivery. Aim C: Compare the breath metabolite and volatile organic compound (VOCs) signature women undergoing induction compared to spontaneous vaginal deliveries.
Kimmerle's anomaly is a bony bridge over the posterior arch of the first cervical vertebra that forms a bony ring. The vertebral artery passes through the opening. This bone bridge could theoretically be an extravasal compression of the artery and disrupt the normal blood flow to the brain. Evaluating the data of X-ray methods, determine the frequency of occurrence and types of Kimmerle anomaly.

To identify factors affecting aetiology and morphology of scoliosis and kyphosis among male adolescents in governmental preparatory and secondary schools in El Kharga city. 3. To assess the effect of scoliosis and kyphosis among male adolescents in governmental preparatory and secondary schools in El Kharga city on related life style aspects.
The aim of our study is to investigate the pregnancy rates in women with normal uterine cavity ,with and without cervical abnormalities.
The limb deformity in children include congenital limb malformations or acquired from the damage of epiphyseal plate which caused by tumor, inflammation and trauma. Due to the complexity of the disease itself, rapid dynamic development and the characteristics of children's growth and development, the deformities are constantly changing. In addition, the serious lack of clinical diagnosis and treatment resources in the Department of Pediatric Orthopedics has led to the misdiagnosis and improper treatment of children's limb deformities. Thus, its necessary to find an intelligent way to help doctor to early diagnosis of limb deformity and provide a proper treatment in children.
The intention of the study is to investigate whether Deep Brain Stimulation (DBS) will improve postural deformities of patients with Parkinson's disease.
