Filter by:The purpose of this study is to evaluate the efficacy of spinal analgesia for minor laparotomic hepatectomy compared with epidural analgesia, monitoring visual analog scale (VAS). The investigators expect at least the same post-operative pain control in the two groups (non inferiority of pain control with spinal analgesia compared to epidural analgesia). Second endpoint is to verify whether after spinal analgesia there is a decrease in patient's length of hospitalization according to enhanced recovery after surgery (ERAS) principles.
The investigators will compare the effects of PSGB(percutaneous stellate ganglion block) in patients with recurrent sustained VT/VF in spite of appropriate medical therapy and cardio-version/ defibrillation after correction of underlying correctable factors with those without PSGB by prospective randomized trail. PSGB will be performed every 3 days by anesthesiology specialist after cardiologist's request, until the stabilization of VT/VF. We will compare the frequency and episode number of VT/VF, procedure related complication, acute and long-term mortality.
Multiple sclerosis (MS) is characterized pathologically by demyelination, axonal loss, and glial scar formation. Clinically, most patients have a relapsing-remitting course of MS (RRMS) that over time may become progressive without remissions - a secondary progressive MS (SPMS). About 15% of patients have a progressive course from onset which is called primary progressive (PP). Currently, there is no approved treatment for PPMS and for SPMS only therapy with mitoxantrone showed mild effect. Thus, more effective therapies need to be developed for treatment of SPMS and PPMS. Methotrexate (MTX), an anti-metabolite, has been in clinical use since 1948 when it was found to produce temporary remission of acute childhood leukemia. There are accumulating evidences that in progressive MS patients there are follicular lymphoid structures in the meninges and in the Virchow-Robin spaces. Therefore, intrathecal therapy may target the pathological follicular lymphoid activity. The safety of intrathecal MTX (ITMTX) has been demonstrated by its widespread use in treating lymphoproliferative diseases and leptomeningeal metastases. Sadik et. Al. reported about the feasibility and safety of using intrathecal methotrexate (ITMTX) as a treatment for unresponsive patients with progressive forms of MS. In their open label study they found that ITMTX may have a beneficial effect in progressive forms of MS and that it was well tolerated with no serious adverse events. The investigators aim is to evaluate the efficacy , safety and tolerability of intrathecal methotrexate administration every 3 months in progressive 30 patients with progressive MS. The investigators will evaluate clinical, laboratory evaluation of the blood and cerebrospinal fluid as well as the MRI scans of the participants. Each patient will be treated 4 times for 1 year with the option to continue for another 1 more year with the same protocol.
In patients with ST elevation myocardial infarction (STEMI) the treatment goal is revascularization of the occluded artery with the use of primary percutaneous coronary intervention (PCI). There is a large subset of patients with STEMI who also have significant disease in arteries other than the site of occlusion, and away from the culprit artery. It is estimated that up to 50% have disease of more than 50% in the non-culprit arteries. The evidence on how to treat those patients with multi vessel disease is conflicting. Earlier large-scale studies and registries have suggested early and complete revascularization is of no benefit or even harmful. More recent studies have showed the opposite of that. The CVLPRIT study showed that early complete revascularization or preventive PCI reduced primary endpoint of a composite of all cause mortality, myocardial infarction and need for repeat revascularization. The benefit was mainly due to reduced repeat revascularization in the more intensive intervention group. The PRAMI study showed very similar results as well. The use of Fractional flow Reserve (FFR) in deciding complete revascularization has also showed conflicting results so far. A previous trial showed that FFR guided intervention post STEMI increased MACE. This was conflicted with more recent study, which showed FFR guided complete revascularization improved outcome when compared with more conservative treatment of ischaemia driven intervention. In this study, the investigators are going to assess the issue of staged revascularization guided by FFR or by angiogram, compared to the standard treatment of ischaemia driven revascularization
To study the association between maternal serum vitamin C concentration in women with preterm premature rupture of membranes (PPROM) and women without PPROM.
To assess the safety and efficacy of intravitreal aflibercept injection in the regression of retinal neovascularization secondary to high-risk PDR. To characterize baseline/post-induction/maintenance levels of proinflammatory mediators in patients with high-risk PDR
The goal of this project is to find a series novel biomarkers by differential proteomic techniques that can improve the early diagnosis and develop a more efficient therapy to enhance ARDS patient survival rate.
Peripheral vascular disease (PVD) is a common disease of impaired blood flow resulting in the compromised tissue perfusion of lower limbs. PAD patients can experience pain, diminished exercise capacity, and tissue loss, with some ultimately requiring amputation. The economic burden of PVD is significant. In the United States alone, PVD accounts for over $20 billion in annual healthcare related costs. The demand for the development of an effective method to characterize the viability of PVD wounds has resulted in the emergence of several innovative techniques. Commonly used diagnostic methods are ankle-brachial index (ABI), pulse volume recordings, duplex ultrasonography, venous plethysmography, Transcutaneous oxygen tension (TcPO2), toe pressures, angiography by X-ray, computed tomography, and magnetic resonance imaging. Currently, angiography remains the diagnostic gold standard. However, many of these techniques lack the ability to triage and adequately determine the viability of the wound. In addition, there remains a need for effective triage technologies to help clinicians decide whether surgical management is needed. Early determination of surgical versus conservative management may help to improve patient functional outcomes, reduce mortality rates, and prevent limb amputation. Near-infrared point spectroscopy (NIRS) is a non-invasively technology with recent applications in PVD wound assessment. To date, studies have demonstrated the validity of NIRS technology in patients with peripheral arterial disease. NIRS measures flow, concentration, and oxygenation of hemoglobin in arterioles, capillaries, and venules several centimeters deep in tissue. The MSID is an evolution of existing NIRS imaging devices and has become a portable and functional commercial device produced by KENT imaging (Calgary, Canada). Using this new and clinically applicable NIRS technology designed for assessing wound perfusion and oxygenation, this study seeks to adequately identify viable from non-viable wounds and to rapidly determine indication for vascular interventions. This technology is well-suited for use in a wound patient population as the measurements times are short and can quickly be used at the patient bed side. As such, this project intends to apply NIR technology to quickly assess PVD in the investigators' patient population.
Mental imagery is effective for improving motor skills as well as increasing muscles strength and size. Strength is also maintained after immobilization of a muscles when engaging in imagery. This may have important implications for rehabilitation settings and for sedentary individuals. We may not be able to get people wot exercise but if they can maintain muscles size and strength via imagery this may have beneficial health and functional outcomes.
