Filter by:Postpartum haemorrhage is a major contributor to maternal mortality in the developing world. The incidence is between 5 and 12% in Jamaica and varies depending on the route of delivery. Misoprostol is a uterotonic agent which has the potential to augment the effects of the standard parenteral oxytocic agents used as best practice in the active management of the third stage of labour, thereby reducing the risk of postpartum haemorrhage and its attendant complications. The Aim of the study is twofold: to show that this additive effect translates to a reduced postpartum haemorrhage rate and secondly to demonstrate reduced side effects of misoprostol resulting from the lower dose and the powdered sublingual administration.
Patients with subarachnoid hemorrhage are prone to suffer from dysnatriemia. Evidence shows that hyponatriemia is associated with increased incidence of vasospasm, brain swelling and mortality in these patients. Patients with subarachnoid hemorrhage often require large amounts of iv fluids in order to maintain euvolemia and support cardiocirculatory function. Prior evidence shows that the type of infusion fluid significantly influences blood sodium content. Hence, this study evaluated whether the sodium content of the infusion solution impacts mortality and morbidity in patients with subarachnoid hemorrhage.
Transcranial Doppler ultrasound (TCD) monitoring and CT-scanner perfusion are useful but imperfect tools to identify vasospasm and allow intervention to avoid infarction. Permanent monitoring of cerebral tissue oximetry (rSO2) by NIRS, a noninvasive method could allow better vasospasm detection. This study will evaluate diagnostic accuracy of cerebral oxymetry (NIRS) -by rSO2 measurement - in order to detect vasospasm in patient with severe subarachnoid hemorrhage compare to standard monitoring tools.
A randomized, controlled study is conducted. 120 patients with post-stroke shoulder-shoulder syndrome who meet the inclusion criteria are randomized into treatment group and control group, 60 patients in each group. The treatment group is treated with Qingpeng ointment. The goal of this trial is to verify the clinical efficacy of Tibetan medicine Qingpeng ointment in improving post-stroke shoulder-hand syndrome, and to investigate its effect on pain level, swelling degree, hand movement function, activity and activities of daily living.
Randomized, open label study of intravenous terlipressin infusion vs. bolus for the treatment of variceal hemorrhage. 24 hour regimen consisting of intravenous terlipressin will be used either at a rate of 0.5mg/hour or 2mg bolus every 4 hourly. Participants will be randomized into intervention and control arm using block randomization by computer generated random numbers. Efficacy will be assessed by clinical improvement in symptoms and signs of GI bleed. To assess safety, frequency and degree of adverse reactions will be observed. Periodic assessments until 5 days will be done consisting of physical examination, safety assessments, vital signs and lab tests.
Acute variceal bleeding is one of the critical complications in patients with cirrhosis. Due to remarkable improvements in diagnostic and therapeutic modalities such as vasoactive agents, endoscopic therapy and antibiotics, the overall prognosis has been improved during the past several decades. However, it is still associated with increased mortality that is still around 20% at 6 weeks. Patients with advanced cirrhosis have an intense overactivity of the endogenous vasoactive systems characterized by arterial hypotension and low peripheral vascular resistance. Severe renal vasoconstriction in consequence of marked arterial vasodilatation in splanchnic circulation triggers the reduction of glomerular filtration rate, and thus induces acute kidney injury (AKI)/hepatorenal syndrome (HRS), which have been further implicated in the increasing mortality in patients with cirrhosis. Renal functional magnetic resonance imaging (fMRI), a technique considered superior to the most common method used to estimate the glomerular filtration rate, allows for non-invasive, accurate measurements of renal structures and functions in both animals and humans. It has become increasingly prevalent in research and clinical applications. In recent years, renal fMRI has developed rapidly with progress in MRI hardware and emerging post-processing algorithms. Function related imaging markers could be acquired via renal fMRI, encompassing water molecular diffusion, perfusion, and oxygenation. The study will use phase contrast - MR angiography, intravoxel incoherent motion - diffusion weighted imaging (IVIM-DWI) and blood-oxgen-level-dependent (BOLD)-MRI to evaluate renal functional changes after using vasoactive medications in patients with cirrhosis. The rationale for the use of vasoactive medications, including terlipressin and octreotide, is to produce splanchnic vasoconstriction and reduce portal blood flow and portal pressure, thereby underpinning the application of these vasoactive drugs in the management of cirrhotic patients with acute variceal bleeding. Meanwhile, terlipressin has been recommended as the international first-line pharmacological therapy for the treatment of HRS because terlipressin may improve renal hemodynamics, improve renal function and potentially enable HRS a reversible condition without the need of liver transplantation. However, the renal protection effect of terlipressin vs. octreotide remains unknown. In this study, the investigators aim to conduct a multicenter, single-blind randomized controlled trial to compare the renal protection effect of terlipressin vs. octreotide assessed by fMRI in the management of cirrhotic patients with acute variceal bleeding.
The investigators will perform follow-up on 500 cases of deep and lobar intracerebral hemorrhage to perform advanced neuroimaging before 45 days post stroke, and evaluations of motor and cognitive function at baseline, 3 months and 6 months to determine predictors of recovery, progressive cognitive or functional impairment.
The main objective of this study is to determine the one-year neurological outcome of patients admitted to an intensive care unit (ICU) for a primary and spontaneous supratentorial intracerebral hemorrhages (ICH).
The objectives of the RECONFIG clinical study are to : 1. To identify the time to the first diagnosis of cognitive motor dissociation (CMD) in intracerebral hemorrhage (ICH) patients and to investigate whether these patients will clinically follow commands earlier after the hemorrhage. 2. To determine whether CMD independently predicts long term functional outcomes (6-month mRS scores) in ICH patients, and is associated with long term cognitive and quality of life outcomes. 3. To determine the EEG response to verbal commands of the motor imagery paradigm between patients with and without sensory aphasia. The overall goal is to determine predictors and the trajectory of neurological recovery.
By combination of plasma (Aβ40, Aβ42, total tau, and phosphorylated tau, etc.), genetic (ApoE ε2 or ε4 allele), MRI (cerebral perfusion, microbleeds, cortical superficial siderosis, enlarged perivascular space, etc.) and PET imaging (amyloid and tau) biomarkers, the study aims to 1. Enhance the diagnostic potentials of the radiological biomarkers by combining MRI and amyloid PET in CAA patients. 2. Investigate the biological pathogenesis in CAA patients using the less invasive plasma biomarkers and to correlate with structural and function imaging, including MRI, amyloid and tau imaging. 3. Study the characteristics of long-term progression of amyloid deposition in CAA patients using the radiological, biochemical and genetic biomarkers. 4. Study the prognosis predicting markers.
