Left ventricular function was assessed in 10 patients with alcoholic cirrhosis and ascites without clinical evidence of heart disease. In the resting state pulmonary wedge pressure (PWP) was normal (average 9.7 mm Hg), cardiac output (CO) was elevated (average 9.7 L/min) and systemic vascular resistance (SVR) was low (average 825 dynes-sec-cm-5). During infusion of angiotensin in a dose suffici...

BACKGROUND Evidence for longer term exercise delivery for people with Parkinson's disease (PwP) is deficient. AIM Evaluate safety and adherence to a minimally supported community exercise intervention and estimate effect sizes (ES). METHODS 2-arm parallel phase II randomised controlled trial with blind assessment. PwP able to walk ≥100 m and with no contraindication to exercise were recruit...

The PWP method was introduced by Dı́az in 2009 as a technique for measuring indirect influences in complex networks. It depends on a matrix D, provided by the user, called the matrix of direct influences, and on a positive real parameter λ which is part of the method itself. We study changes in the method’s predictions as D and λ vary.

Studies of cardiac performance in hypertension have often been restricted to cardiac output determinations, although the latter alone are inadequate for that purpose. To define the range of cardiac performance in hypertension, the response of left ventricular filling pressure to increased workload (static exercise) was determined in 39 subjects--eight normotensive (NT) volunteers, seven patient...

BACKGROUND Falls amongst people with Parkinson's (PwP) result in significant disability and reduced quality of life. There is emerging evidence that exercise-based and physiotherapeutic interventions are of benefit for improving fall risk factors, such as balance. However, the benefit, in terms of preventing falls, is mixed. The development of effective interventions has been identified as the ...

Stability Analysis and Controller Synthesis for a Class of Piecewise Smooth Systems Behzad Samadi, Ph.D. Concordia Unviersity, 2008 This thesis deals with the analysis and synthesis of piecewise smooth (PWS) systems. In general, PWS systems are nonsmooth systems, which means their vector fields are discontinuous functions of the state vector. Dynamic behavior of nonsmooth systems is richer than...

BACKGROUND People with Parkinson's (PwP) experience frequent and recurrent falls. As these falls may have devastating consequences, there is an urgent need to identify cost-effective interventions with the potential to reduce falls in PwP. The purpose of this economic evaluation is to compare the costs and cost-effectiveness of a targeted exercise programme versus usual care for PwP who were at...

BACKGROUND Public-private partnerships (PPP) could be effective in scaling up services. We estimated cost and cost-effectiveness of different PPP arrangements in the provision of tuberculosis (TB) treatment, and the financing required for the different models from the perspective of the provincial TB programme, provider, and the patient. METHODS Two different models of TB provider partnership...
