Noninvasive ventilation (NIV) is an alternative form of ventilatory support in critical care encompassing different modes of ventilation such as continuous positive airway pressure (CPAP), bilevel positive airway pressure (BiPAP) and high flow nasal cannula ventilation. Although numerous studies on adults exit in literature, the aspects of this ventilatory support is limited in pediatric age groups. Early recognition of respiratory failure and initiation of NIV in a pediatric patient would positively affect prognosis by avoiding certain complications of endotracheal intubation and mechanical ventilation and adds certain advantages. Decreasing re-intubation rates for the ones who are extubated but necessitating further oxygen support is another advantage of NIV. Although numerous studies on adults exit in literature, the aspects of this ventilatory support is limited in pediatric age groups. Besides, success as well as failure and complication rates in pediatric age groups vary extensively. This multi-centered, prospective cohort study is planned to observe the epidemiologic perspectives of study group within underlying problems, success rates between different age groups, complication and re-intubation rates and finally its' effect on prognosis and long term survival in a year period. Hence we believe results of this study would allow us to improve our knowledge on using this technique, applying different modes and parameters appropriately and design criteria to guide clinician in deciding which group of patients would benefit from NIV techniques.
The purpose of this study is to demonstrate the superiority of LCZ696 over individualized medical therapy for comorbidities in reducing N-terminal pro-brain natriuretic peptide (NT-proBNP) and improving exercise capacity and HF symptoms in patients with heart failure with preserved ejection fraction (HFpEF).
Objectives: To investigate whether respiratory variations of inferior vena cava diameters (cIVC) predict fluid responsiveness in spontaneously breathing patients with septic acute circulatory failure and irregular heartbeats. Design: Prospective, bicentric study, intensive care units. Patients and measures: Spontaneously breathing patients with sepsis and clinical signs of acute circulatory failure are included. A positive response to fluid loading (FL) is defined as an increase of the stroke volume (SV) >10%. The investigators measured the minimum inspiratory and maximum expiratory diameters of the IVC (idIVC and edIVC) during standardized (st) and unstandardized (ns) breathing. The investigators calculated cIVCst and cIVCns before a 500ml-colloid FL.
Hypovolemia and acute circulatory failure affects more than 60% of patients hospitalized in intensive care or resuscitation. The volume expansion (VE) by fluid replacement therapy is the first treatment improve circulatory function. However, too much VE can be harmful. So, the use of dynamic predictive indicators of fluid responsiveness is recommended in patients with sepsis.In patients with spontaneous ventilation, few studies have evaluated these parameters. In mechanical ventilation, indices based on the respiratory variation of the diameters of vena cava have been studied and validated to predict the response to VE. However there is no similar study in spontaneously breathing patients without ventilatory support. The investigators hypothesize that the respiratory variations in the IVC diameters and femoral artery flow during standardized respiratory cycles are predictive factors of fluid responsiveness in spontaneously breathing patients with sepsis, acute circulatory failure, and regular cardiac rhythm.
Excessive vascular endothelial growth factor (VEGF) plays a key part in promoting neovascularization and edema in neovascular (wet) age-related macular degeneration (nAMD). VEGF inhibitors (anti-VEGF), including ranibizumab (LUCENTIS®, Genentech) and aflibercept (EYLEA®, Regeneron), have been shown to be safe and effective for treating nAMD and have demonstrated improvement in vision. However, anti-VEGF therapy is administered frequently via intravitreal injection and can be a significant burden to the patients. RGX-314 is a recombinant adeno-associated virus (AAV) gene therapy vector carrying a coding sequence for a soluble anti-VEGF protein. The long-term, stable delivery of this therapeutic protein following a 1 time gene therapy treatment for nAMD could potentially reduce the treatment burden of currently available therapies while maintaining vision with a favorable benefit:risk profile.
The purpose of this research is to collect preliminary data in preparation for conducting a randomized clinical trial to determine the relative effectiveness of vision rehabilitation in improving overall visual ability (primary aim) and reducing depression (secondary aim) in patients receiving anti-VEGF therapy for neovascular age-related macular degeneration integrated over time.
Purpose: This study will determine the effectiveness of the use of desensitivity gels prior in office bleaching on risk and intensity of tooth sensitivity caused by in-office bleaching using 35% hydrogen peroxide. Materials and Methods: Fifty patients will be selected for this triple-blind, randomized, cross-over, placebo-controlled clinical trial. 10 minutes prior to bleaching procedure, patients will receive the potassium oxalate 5% desensitivity gel and placebo application on vestibular surface. The whitening treatment with 35% hydrogen peroxide will be carried out in two sessions with a 7-day interval. Tooth sensitivity will be assessed before, during and 24 hours after the procedure using analog visual and verbal scales. Color alteration will be assessed by a Classical guide scale. Relative risk to sensitivity will be calculated and adjusted by session; while comparison of overall risk will performed by McNemar's test. Data on the sensitivity level for both scales and color shade will be subjected to the Friedman, Wilcoxon and Mann-Whitney tests, respectively (α = 0.05)
In the U.S. alone, over 300,000 people per year have sudden out-of-hospital cardiac arrest (OHCA), and less than 1 out of 10 survive. The current standard practice for treating OHCA is to perform cardiopulmonary resuscitation (CPR) and Advanced Cardiovascular Life Support (ACLS) at the scene until either the heart is restarted or resuscitation efforts are considered hopeless and discontinued. An alternative strategy for those with refractory OHCA is expedited transport with ongoing mechanical CPR to an Emergency Department capable of performing extracorporeal cardiopulmonary resuscitation (ECPR). The purpose of study is to test if this strategy is feasible and beneficial.
Temporomandibular joints dysfunction is a functional disorder concern with the abnormal functioning of the muscles of the stomatognathic system, temporomandibular joints involved in the dynamic movements of the jaw and surrounding structures. The aim of the study was to compare the level of C-reactive protein in patients with pain and painless form of temporomandibular joints dysfunction.
