Feasibility of Canine Therapy Among Hospitalized Pre-Heart Transplant Patients.

OBJECTIVES: Canine-assisted therapy (CAT) has been used in many settings with much success, yet no study has assessed its feasibility and receptiveness in hospitalized patients awaiting heart transplantation. METHODS: Patients admitted to our institution with a status I for heart transplantation during a 12-month period (April 2014-April 2015) were prospectively included in a feasibility pilot study. Patients were included if there was no history of transmittable disease or active infectious process and consented for study participation. Each patient was visited daily by a canine and quantitative and qualitative data regarding the visit were obtained. RESULTS: A total of 11 patients were included in the study. Most patients were men (n = 8, 72.7%) and the average age was 51.1 years. A total of 146 individual therapies took place, totaling 2718 minutes of CAT during the study period. Each patient had an average of 13.3 visits and each visit had an average duration of 14.7 minutes. Patient receptiveness, as measured by the CAT volunteer, averaged 9.9 (scale 0-10). No reports of infection transmission occurred. CONCLUSIONS: Our study found that CAT among hospitalized pre-heart transplant patients is feasible and is a welcomed adjunct to usual medical care.

Towards a participatory framework for improving water & health outcomes: A case study with Maasai women in rural Tanzania.

Rural communities in sub-Saharan Africa (SSA) are disproportionately burdened by a pervasive lack of access to safe drinking water. Widespread programmatic failure in the water, sanitation, and hygiene (WaSH) sector has resulted in particularly slow progress in alleviating these challenges in the region. Drawing from decolonial and participatory methodological scholarship, this research demonstrates how geographically and demographically specific, locally controlled, and long-term educational programming can improve health and wellness outcomes when associated with a technological intervention. Specifically, consultations between January 2015 and August 2018 were followed by an iterative and community-driven program development process between January and July 2019. Fifty Maasai women were subsequently recruited to participate and were provided with a point-of-use water treatment technology in August 2019. These women engaged in a series of three 14-week WaSH education programs over an 18-month evaluation period. Results showed that 38% of participants reported regular diarrhea at baseline, decreasing to 8%, 0%, and 3% immediately after each of the three WaSH education programs were provided at 3, 12, and 18 months. Interim measurements taken between WaSH programs showed 35% of participants (at 6 months) and 5% of participants (at 15 months) reporting regular diarrhea. A trend of improvement was thus observed over the study period, though the increase in reported diarrhea at 6 months demonstrates the need for long-term commitment on the part of WASH practitioners when engaging with end users to achieve sustained change. Further, this research highlights the importance of participatory program development and pedagogical approaches in WaSH interventions, where local control of study objective determination and implementation, combined with consistent and long-term engagement, can facilitate sustained technology use and associated reductions in diarrhea.

Exercise performance increases coincident to body weight over the first two years following cardiac transplantation.

BACKGROUND: To determine whether exercise performance changed over time once patients stabilized after heart transplantation, metabolic stress testing was performed in patients one and two yr post-heart transplantation. METHODS: The patient cohort includes those transplanted in our program who survived at least two yr and were able to perform metabolic stress tests during their one- and two-yr annual evaluations. Standard stress test parameters were assessed, including weight, body surface area, rest and exercise heart rate (HR) and blood pressure (BP), exercise time, anaerobic threshold (AT), and maximum VO2 (MVO2). Ejection fraction by echo was also collected. Each patient served as their own control and data were compared using paired t-testing. RESULTS: Fifty patients were included in the cohort, 48 of whom were able to exercise to at least AT. Patient weight increased from year 1 to year 2 (82.4 ± 15.1 vs. 85.0 ± 17.0 kg, p = 0.035). Systolic BP increased approximately 40 mmHg with exercise with no change in diastolic BP, and there was no difference between years 1 and 2. HR increased approximately 25 bpm with exercise. There was no difference in resting HR but exercise HR increased significantly between yrs (148 ± 15 bpm vs. 154 ± 18 bpm, p = 0.017). Both VO2 at AT and MVO2 increased significantly from year 1 to year 2 (1116 ± 347 mL/min vs. 1192 ± 313 mL/min, p = 0.049 and 1523 ± 337 mL/min vs. 1599 ± 356 mL/min, p = 0.012, respectively) but when corrected for body weight, there were no differences (VO2-AT 13.6 ± 4.0 mL/kg/min vs. 14.0 ± 4.0 mL/kg/min; MVO2 18.7 ± 4.2 mL/kg/min vs. 18.8 ± 4.1 mL/kg/min). All other measured parameters were not different. There was a weak but statistically significant correlation between change in peak HR and change in VO2 at AT between one and two yr post-transplantation (r = 0.30, p = 0.04). CONCLUSIONS: We conclude that exercise performance as measured by VO2 can increase over time post-heart transplantation and in our cohort appears to be related to both an increase in body weight and an increase in HR from years 1 and 2.
