O-2-17. Influence of different types of orthoses on muscle synergy control during gait in stroke patients with hemiparesis

The purpose of this study was to verify the influence of lower limb orthoses on muscle synergy control during gait in stroke patients with hemiparesis. In four subjects with acute stroke, surface EMG signals from eight muscles of the paretic lower limb were measured during gait in two conditions (ankle foot orthosis; AFO or knee ankle foot orthosis; KAFO). The number of modules, muscle weightings and activation timing profile of each module were analyzed using non-negative matrix factorization. In two subjects (Fugl Meyer Assessment; FMA  > 20) who walked with mild assistance, three modules were identified during gait with KAFO, whereas two modules were identified with AFO.

Authors: Lee YH, Jang HW, Park CH, An SM, Lee EK, Choi BM, Noh GJ Abstract BACKGROUND: The aim of intraoperative fluid therapy is to avoid both hypovolemia and hypervolemia; however, the patient's exact volume status is difficult to determine during surgery. Fluid optimization guided by stroke volume variation (SVV) has been widely used in patients undergoing major open abdominal surgery. The aim of this study was to evaluate the changes in plasma volume before and after surgery following SVV-guided fluid therapy. METHODS: Patients were randomly allocated into one of two groups according to the SVV criteria for...

ConclusionsIn the largest analysis of transplanted donor hearts with transient LVSD, 1 in 4 had RWMAs on the initial TTE; but this was not associated with adverse post-transplant outcomes. Donor hearts with initial LVSD should be pursued irrespective of TTS-like hypokinesis or other RWMAs.Graphical abstract

In this study, we evaluate whether thrombocytopenia following CPB is an independent risk factor for post-operative morbidity and mortality.MethodsWe retrospectively evaluated 1,364 patients requiring CPB at University of Colorado Hospital between January 2011 and May 2016. Platelet nadir, absolute change in platelets, and percent change in platelets were modeled as continuous variables. Patients with post-operative thrombocytopenia (defined a nadir

CONCLUSION: During the last century, AADRs among males declined more slowly than among females. Although the gap diminished in recent decades, exploration of social and behavioral factors may inform interventions that could further reduce death rates among males.

Authors: de Montalembert M, Tshilolo L, Allali S Abstract As more children are appropriately being diagnosed, the burden of sickle cell disease is increasing greatly in Africa and in high-resource countries such as the United States and Europe. Early management is mandatory, but newborn screening is not implemented everywhere. Point-of-care testing devices are increasingly being used in low-resource countries, showing good sensitivity and specificity. Because the diagnosis is often traumatic for the families, the announcement should be made by an experienced person. The development of care networks is urgently requ...

Authors: Cohen AT, Hunt BJ Abstract The direct oral anticoagulants (DOACs) have transformed the management of thrombotic disorders. Large clinical trials have demonstrated that DOACs can replace vitamin K antagonists (VKAs) in the 2 existing major indications for anticoagulation: the prevention of stroke in atrial fibrillation and the acute treatment and secondary prevention of venous thromboembolism (VTE); this literature is widely known. In this article, we will concentrate on the less well-discussed benefits of the use of DOACs-using low doses as primary and secondary prophylaxis in both venous and arterial thro...

Authors: Leebeek FWG, Muslem R Abstract Chronic heart failure (HF) is a growing health problem, and it is associated with high morbidity and mortality. Left ventricular assist devices (LVADs) are nowadays an important treatment option for patients with end-stage HF not only as a bridging tool to heart transplantation but also, as a permanent therapy for end-stage HF (destination therapy). The use of LVAD is associated with a high risk for bleeding complications and thromboembolic events, including pump thrombosis and ischemic stroke. Bleeding is the most frequent complication, occurring in 30% to 60% of patients, b...

Authors: Kimpton M, Siegal DM Abstract A 77-year-old man with atrial fibrillation and a CHA2DS2Vasc score of 6 for hypertension, age, diabetes, and previous stroke is brought to the emergency department with decreased level of consciousness. He is anticoagulated with rivaroxaban (a direct oral factor Xa inhibitor [FXaI]) and received his last dose about 4 hours before presentation. Urgent computed tomography of the head shows intracerebral hemorrhage. Because of his previous stroke, the patient's family is concerned about treating the bleed with pharmacological agents that may increase the risk of stroke. What are ...
