NCT01926691
Background: Recent studies have demonstrated that even mild stroke survivors experience residual damage, which persists and in fact increases in subsequent years. About 45% of stroke victims remain with different levels of disability. While studies on cognitive impairment and dementia after stroke are receiving increasing clinical attention, the underlying pathophysiology is poorly understood. Identifying the mechanisms involved and recognizing early biomarkers for individual vulnerability, require a multi-modal approach, as the mechanisms involved in cerebrovascular disease and individual trajectories of post-stroke recovery may impact upon each other on various levels. Aims and Hypothesis: To date there is no single measure that can be used to identify patients who are prone to develop cognitive impairment and other disabilities from those with better recovery prospects. We hypothesize that data based on biochemical, neuroimaging, genetic and psychological measures can, in aggregate, serve as better predictors for subsequent disability, cognitive and neurological deterioration, and suggest possible interventions. Design: The TABASCO (Tel-Aviv Brain Acute Stroke Cohort) study, a prospective cohort study aim to recruit about approximately 1125 consecutive first-ever mild-moderate stroke patients. It is designed to evaluate the association between predefined demographic, psychological, inflammatory, biochemical, neuro-imaging and genetic markers, measured during the acute phase, and long-term outcome: subsequent cognitive deterioration, vascular events (including recurrent strokes), falls, affective changes, functional everyday difficulties and mortality. Discussion: This study is an attempt to comprehensively investigate the long term outcome of mild-moderate strokes. Its prospective design will provide quantitative data on stroke recurrence, the incidence of other vascular events and the evaluation of cognitive, affective and functional decline. Identifying the factors associated with post stroke cognitive and functional decline could potentially yield more effective therapeutic approaches. The investigators believe that an extensive approach of analyzing the interaction between different risk factors would more accurately predict neurological and cognitive deterioration.
NCT04655950
Vertebral osteomyelitis is an infection of the intervertebral disk and adjacent vertebral plates with a non-negligible risk of neurological complications and handicap. If there are clear recommendations dealing with antibiotic therapy and surgery indications for this pathogen, the question of the immobilization will be remaining debate. The aim of the study was to describe protocols and practices for the immobilization of vertebral osteomyelitis in different French hospitals and bone and joint infections Centers. The secondary objectives were to evaluate the frequency of neurological complications in a large prospective cohort, and to identify clinical and imaging risk factors for neurological complications. The investigators also aim to search for association between type and duration of spine immobilization and neurological status at the end of follow-up.
NCT01541241
THE AIM OF THE this study is to assess the hemodynamic changes of uterine artery in patients with CIUD induced bleeding by using transvaginal color Doppler indices (uterine artery resistance index and pulsatility index) to prove the relationship between these changes and bleeding in these patient .
NCT02181478
This clinical trial studies intra-osseous donor umbilical cord blood and mesenchymal stromal cell co-transplant in treating patients with hematologic malignancies. Giving low doses of chemotherapy and total-body irradiation before a co-transplant of donor umbilical cord blood and mesenchymal stromal cells into the bone (intra-osseous) helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil at the time of transplant may stop this from happening.

They were randomly assigned into control and study groups of equal numbers each consisted of fifteen children (n=15). Methods: Peabody Developmental Motor Scales 2 (PDMS-2) was used to evaluate each child individually before and after three successive months of treatment (3 sessions per week), to assess 2 subtests (the grasping skills and visual motor integration skills) for all children of both groups. Control group who received a specially selected physical therapy program for hand function on a standard chair seating. Study group who received the same selected program for hand function on adaptive swiss ball seating.
NCT04651946
Liquid biopsy is challenging for the diagnosis of epithelial ovarian cancer (EOC). In this study, we performed the methylation testing of host DNA, namely, OPCML, FODX3 and CDH13, in the peripheral serum to discover the diagnostic and supervision roles of DNA methylation in EOC patients. The study compromises two stages. In the training set, DNA methylation testing is performed in the ovarian tissues from EOC and paired benign ovarian tumor patients. The cut-off values of methylation are produced in this stage. On the meantime, serum DNA methylation testing is also performed to reveal its accordance and accuracy compared with the results of ovarian tissues. In the validation set, serum DNA methylation testing is performed in unselected ovarian tumor patients with definite cut-off values to validate its accuracy based on known histology of ovarian tumors. In training and validation sets, serum DNA methylation is also performed after major surgeries for EOC as to illustrate the changes of methylation testing, therefore, reflection the supervision role of DNA methylation.

All eligible participants accept P16INK4A testing, with cytology and/or hrHPV assay. P16INK4A immunohistochemical staining is performed on the retained specimens of cytology. The primary endpoint is the diagnostic accuracy of P16INK4A compared with cytology and/or hrHPV status based on histology results. The accuracy analysis includes sensitivity, specificity, negative predictive value and positive predictive value.
NCT03666429
The mainstay of treatment in viral upper and lower respiratory tract disease is airway clearance. Viral respiratory tract infections account for a substantial amount of emergency department (ED) visits, financial and stress burden on caregivers. In addition, they also account for a large number of ED return visits. While airway clearance is considered a mainstay of treatment the pragmatic effectiveness of various devices remain unstudied in patients who are discharged from the ED. The objectives of this study are to compare the pragmatic effectiveness of two commonly used suction devices the NoseFrida and bulb suction and to provide a descriptive analysis on 72 hour return to ED rates and readmission rates. Patients will be enrolled October 15, 2018 to October 15, 2019 or until NoseFrida supplies are depleted. Fridababy will supply 500 NoseFrida devices and replacement filters. Patients aged 1 day to 24 months presenting Vanderbilt Childrens ED with symptoms of nasal congestion or bronchiolitis who require suctioning and will be discharged from the ED will be approached for enrollment. Exclusion criteria include no upper airway abnormalities or previously enrolled in study. The study design is a prospective and retrospective observational study. We anticipate about 500 patients to be enrolled in this study. Families will then be approached for consent to participate. Caregiver will fill out a data collection form then be instructed on how to use the NoseFrida. Next, family with trial it on their child while in the ED. Caregivers will then fill out a 7 point Likert survey on both the bulb suction and NoseFrida device. The family will go home with this device and a set of replacement filters and instructed to suction their child as needed. The primary investigator (PI) will then complete a 72 hour chart review to determine the number of return to ED visits and readmission rates. To compare ED returns with retrospective data, KSP will conduct a review of the business objects database using ICD9 codes specific for viral respiratory tract infections over the past 3 years to determine a control return ED visit rate. Data will be compared using a paired T-test. If data is not normally distributed we will use a Wilcoxon signed-rank test. We will also use a multivariable logistic model to examine associations adjusted for age and illness severity.
NCT04652323
The aim of this study was to determine the subcutaneous connective tissue reactions to these new materials. Materials and Methods These materials were placed in polyethylene tubes and implanted into the dorsal connective tissue of Sprague Dawley rats. The presence of inflammation, edema, necrosis, dystrophic calcification, and thickness of fibrous capsule formation was recorded by histological examination 7, 30, and 60 days after the implantation procedure. Inflammation scores were defined as follows: 0 = no or few inflammatory cells, no reaction, 1 = \<25 cells, mild reaction; 2 = 25 to 125 cells, moderate reaction; and 3 = ≥125 cells, severe reaction. Fibrous capsule thickness, necrosis, and formation of calcification were recorded.

NCT04368000
Acute respiratory distress syndrome (ARDS) is a major complication among patients with severe disease. In a report of 138 patients with COVID-19, 20% developed ARDS at a median of 8 days after the onset of symptoms, with 12.3% of patients requiring mechanical ventilation. Efficacious therapies are desperately needed. Supportive care combined with intermittent prone positioning may improve outcomes. Prone positioning (PP) of patients with severe ARDS (when combined with other lung-protective ventilation strategies) is associated with a significant mortality benefit. In addition, PP for \>12 hours in severe ARDS is strongly recommended by clinical practice guidelines. The aim of this study is to compare the outcomes of prone positioning versus usual care positioning in non-intubated patients hospitalized for COVID-19.
