As Canadian health policy-makers struggle to contain costs while maintaining quality, patient education is promoted as making patients more effective producers of health and consumers of health care. Assessment of existing psychoeducational interventions has concentrated on knowledge enhancement, behaviour modification, and health status while economic outcomes have remained unexplored. Given that such programs are likely to be effective, but costly, economic appraisals are necessary to convince cost-conscious policy-makers. This manuscript describes a cost-effectiveness evaluation of the Arthritis Self-Management Program (ASMP) that I and my collaborators are conducting by randomizing participants to the ASMP as an adjunct to usual medical care versus usual medical care. Direct and indirect costs are evaluated through self-reporting of health services utilization and diminished productivity and effectiveness through a visual analogue scale and the SF-36. To influence health policy, the results must be disseminated to public health authorities, private insurers, and patient and health professional organizations, thereby encouraging funding, increasing awareness, and promoting participation.
We aimed to identify factors independently associated with the need for inotropic support for low cardiac output or haemodynamic instability after pulmonary artery banding surgery for CHD.
Methods:
We performed a retrospective chart review of all neonates and infants who underwent pulmonary banding between January 2016 and June 2019 at our institution. Bivariate and multivariable analyses were performed to identify factors independently associated with the use of post-operative inotropic support, defined as the initiation of inotropic infusion(s) for depressed myocardial function, hypotension, or compromised perfusion within 24 hours of pulmonary artery banding.
Results:
We reviewed 61 patients. Median age at surgery was 10 days (25%,75%:7,30). Cardiac anatomy was biventricular in 38 patients (62%), hypoplastic right ventricle in 14 patients (23%), and hypoplastic left ventricle in 9 patients (15%). Inotropic support was implemented in 30 patients (49%). Baseline characteristics of patients who received inotropic support, including ventricular anatomy and pre-operative ventricular function, were not statistically different from the rest of the cohort. Patients who received inotropic support, however, were exposed to larger cumulative doses of ketamine intraoperatively – median 4.0 mg/kg (25%,75%:2.8,5.9) versus 1.8 mg/kg (25%,75%:0.9,4.5), p < 0.001. In a multivariable model, cumulative ketamine dose greater than 2.5mg/kg was associated with post-operative inotropic support (odds ratio 5.5; 95% confidence interval: 1.7,17.8), independent of total surgery time.
Conclusions:
Inotropic support was administered in approximately half of patients who underwent pulmonary artery banding and more commonly occurred in patients who received higher cumulative doses of ketamine intraoperatively, independent of the duration of surgery.
To determine if the intention to perform an exercise at speed leads to beneficial alterations in kinematic and kinetic components of the movement in people with post-stroke hemiplegia.
Design:
Comparative study.
Setting:
Subacute metropolitan rehabilitation hospital.
Participants:
Convenience sample of patients admitted as an inpatient or outpatient with a diagnosis of stroke with lower limb weakness, functional ambulation category score ≥3, and ability to walk ≥14metres.
Methods:
Participants performed a single leg squat exercise on their paretic and nonparetic legs on a leg sled under three conditions: 1) self-selected speed (SS), 2) fast speed (FS), 3) jump squat (JS). Measures of displacement, flight time, peak concentric velocity, and muscle excitation (via electromyography) were compared between legs and conditions.
Results:
Eleven participants (age: 56 ± 17 years; median time since stroke onset: 3.3 [IQR 3,41] months) were tested. All participants achieved a jump during the JS, as measured by displacement and flight time respectively, on both their paretic (0.25 ± 0.16 m and 0.42 ± 0.18 s) and nonparetic (0.49 ± 0.36 m and 0.73 ± 0.28 s) legs; however it was significantly lower on the non-paretic leg (p < 0.05). Peak concentric velocity increased concordantly with intended movement speed (JS-FS paretic: 0.96 m/s, non-paretic: 0.54 m/s; FS-SS paretic 0.69 m/s, nonparetic 0.38 m/s; JS-SS paretic 1.66 m/s, non-paretic 0.92 m/s). Similarly, muscle excitation increased significantly (p < 0.05) with faster speed for the paretic and nonparetic vastus lateralis. For gastrocnemius, the only significant difference was an increase during nonparetic JS vs. SS and FS.
Conclusions:
Speed affects the kinematic and kinetic components of the movement. Performing exercises ballistically may improve training outcomes for people post-stroke.

This collection of essays pays tribute to Nancy Freeman Regalado, a ground-breaking scholar in the field of medieval French literature whose research has always pushed beyond disciplinary boundaries. The articles in the volume reflect the depth and diversity of her scholarship, as well as her collaborations with literary critics, philologists, historians, art historians, musicologists, and vocalists - in France, England, and the United States. Inspired by her most recent work, these twenty-four essays are tied together by a single question, rich in ramifications: how does performance shape our understanding of medieval and pre-modern literature and culture, whether the nature of that performance is visual, linguistic, theatrical, musical, religious, didactic, socio-political, or editorial? The studies presented here invite us to look afresh at the interrelationship of audience, author, text, and artifact, to imagine new ways of conceptualizing the creation, transmission, and reception of medieval literature, music, and art.
