Emergent Geographies in Green Energy

A consensus on climate change is spurring an energy transition, but the geography of this transition is uneven and this paper evaluates the energy landscape globally, in the United States and in Colorado. Developed countries have taken the lead in installations and of next generation energy technology ownership. Green electricity has still not achieved parity with fossil fuels, which puts their adoption in the hands of policy makers who are trying to spur innovation with minimal financial disruption. Yet the future of green electricity is in question due to weak and fragmented policy regimes, but also because of inadequate R&D levels. Wind is maturing with large global players and a settling of technology, but solar is marked by scattered manufacturing and fluctuating technology platforms. Within the United States, venture capital (VC) is playing an active role for the cleantech sector; cleantech encompasses broad themes of sustainability to include electricity as well as materials, buildings, water, energy software, and recycling. Cleantech is among the leading economic sectors securing the most VC money and the future geographic landscape is likely to feature California and Massachusetts, who lead as the top destinations of cleantech VC money, but other pockets of innovation are clear. Finally, while large urban utilities are prepared to transition away from fossil fuels, smaller cities and rural areas, for various financial and scale issues are disadvantaged with incorporating more green energy into their electricity mix. This was evident by the results of Colorado\u27s Amendment 37, which created a statewide RPS and passed with strong support in the Denver metro area, but limited support in the rest of the state. Nevertheless, all utilities must now diversify and this study surveyed the managers at the state\u27s rural utilities to gauge their attitudes concerning: carbon legislation, conservation and efficiency programs, and their plans for making the electricity transition. Nearly all of the utilities are making progress, but there is broad apprehension and distrust about mandates and the impacts on their communities

The medical science DMZ: a network design pattern for data-intensive medical science

Abstract: Objective We describe a detailed solution for maintaining high-capacity, data-intensive network flows (eg, 10, 40, 100 Gbps+) in a scientific, medical context while still adhering to security and privacy laws and regulations. Materials and Methods High-end networking, packet-filter firewalls, network intrusion-detection systems. Results We describe a “Medical Science DMZ” concept as an option for secure, high-volume transport of large, sensitive datasets between research institutions over national research networks, and give 3 detailed descriptions of implemented Medical Science DMZs. Discussion The exponentially increasing amounts of “omics” data, high-quality imaging, and other rapidly growing clinical datasets have resulted in the rise of biomedical research “Big Data.” The storage, analysis, and network resources required to process these data and integrate them into patient diagnoses and treatments have grown to scales that strain the capabilities of academic health centers. Some data are not generated locally and cannot be sustained locally, and shared data repositories such as those provided by the National Library of Medicine, the National Cancer Institute, and international partners such as the European Bioinformatics Institute are rapidly growing. The ability to store and compute using these data must therefore be addressed by a combination of local, national, and industry resources that exchange large datasets. Maintaining data-intensive flows that comply with the Health Insurance Portability and Accountability Act (HIPAA) and other regulations presents a new challenge for biomedical research. We describe a strategy that marries performance and security by borrowing from and redefining the concept of a Science DMZ, a framework that is used in physical sciences and engineering research to manage high-capacity data flows. Conclusion By implementing a Medical Science DMZ architecture, biomedical researchers can leverage the scale provided by high-performance computer and cloud storage facilities and national high-speed research networks while preserving privacy and meeting regulatory requirements

A targeted e-learning program for surgical trainees to enhance patient safety in preventing surgical infection.

INTRODUCTION: Surgical site infection accounts for 20% of all health care-associated infections (HCAIs); however, a program incorporating the education of surgeons has yet to be established across the specialty. METHODS: An audit of surgical practice in infection prevention was carried out in Beaumont Hospital from July to November 2009. An educational Web site was developed targeting deficiencies highlighted in the audit. Interactive clinical cases were constructed using PHP coding, an HTML-embedded language, and then linked to a MySQL relational database. PowerPoint tutorials were produced as online Flash audiovisual movies. An online repository of streaming videos demonstrating best practice was made available, and weekly podcasts were made available on the iTunes© store for free download. Usage of the e-learning program was assessed quantitatively over 6 weeks in May and June 2010 using the commercial company Hitslink. RESULTS: During the 5-month audit, deficiencies in practice were highlighted, including the timing of surgical prophylaxis (33% noncompliance) and intravascular catheter care in surgical patients (38% noncompliance regarding necessity). Over the 6-week assessment of the educational material, the SurgInfection.com Web pages were accessed more than 8000 times; 77.9% of the visitors were from Ireland. The most commonly accessed modality was the repository with interactive clinical cases, accounting for 3463 (43%) of the Web site visits. The average user spent 57 minutes per visit, with 30% of them visiting the Web site multiple times. DISCUSSION: Interactive virtual cases mirroring real-life clinical scenarios are likely to be successful as an e-learning modality. User-friendly interfaces and 24-hour accessibility will increases uptake by surgical trainees

Preventing infection in general surgery: improvements through education of surgeons by surgeons.

Surgical patients are at particular risk of healthcare-associated infection (HCAI) due to the presence of a surgical site leading to surgical site infection (SSI), and because of the need for intravascular access resulting in catheter-related bloodstream infection (CRBSI). A two-year initiative commenced with an initial audit of surgical practice; this was used to inform the development of a targeted educational initiative by surgeons specifically for surgical trainees. Parameters assessed during the initial audit and a further audit after the educational initiative were related to intra- and postoperative aspects of the prevention of SSIs, as well as care of peripheral venous catheters (PVCs) in surgical patients. The proportion of prophylactic antibiotics administered prior to incision across 360 operations increased from 30.0% to 59.1% (P72h (10.6% vs 3.1%,

Training and match load in professional rugby union: Do contextual factors influence the training week?

Background: Rugby union demands a multifaceted approach to training, given the multiple physical and technical attributes required to play the sport. Objectives: The aim of this study is to describe the distribution of training throughout the week and investigate how this may be influenced by match-related factors. Methods: Training load data (session Rating of Perceived Exertion [sRPE], total distance and high-speed running [HSR]) were collected from six professional English rugby teams during the 2017/18 season. Five contextual factors were also recorded including: standard of opposition, competition type, result of previous fixture, surface type, and match venue. Results: The day prior to matches demonstrated the lowest training load (101 AU (95% CIs: 0-216 AU) , 1 047 m (95% CIs:1 128-1 686 m) and 59 m (95% CIs: 0-343 m), respectively), while four days prior to the match demonstrated the highest training load (464 AU (95% CIs: 350-578), 2 983 m (95% CIs: 2 704-3 262m) and 234m (95% CIs: 0-477m), respectively). Of the five contextual factors, competition type was the only variable that demonstrated greater than trivial findings, with training before European fixtures the lowest stimulus across the four different competition types. Standard of opposition, previous result, surface type and venue had only trivial effects on training load (effect sizes = -0.13 to 0.15). Conclusion: Future studies should outline the distribution of other training metrics, including contact and collision training. This study provides a multi-club evaluation that demonstrates the variety of loading strategies prior to competitive match play and highlights competition type as the most influential contextual factor impacting the average training load

Success of an International Learning Health Care System in Hematopoietic Cell Transplantation: The American Society of Blood and Marrow Transplantation Clinical Case Forum

The ASBMT Clinical Case Forum (CCF) was launched in 2014 as an online secure tool to enhance interaction and communication among hematopoietic cell transplantation (HCT) professionals worldwide through the discussion of challenging clinical care issues. After 14 months, we reviewed clinical and demographical data on cases posted in the CCF from 1/29/2014 to 3/18/2015. A total of 137 cases were posted during the study period. Ninety-two cases (67%) were allogeneic HCT, 29 (21%) autologous HCT and in 16 (12%) the type of transplant (auto vs. allo) was still under consideration. The diseases most frequently discussed included non-Hodgkin lymphoma (NHL; n = 30, 22%), acute myeloid leukemia (AML; n = 23, 17%) and multiple myeloma (MM; n = 20, 15%). When compared with the US transplant activity reported by the US Department of Health and Human Services, NHL and acute lymphoblastic leukemia cases were overrepresented in the CCF while myeloma was underrepresented (P < 0.001). A total of 259 topics were addressed in the CCF with a median of two topics/case (range 1-6). Particularly common topics included whether transplant was indicated (n = 57, 41%), conditioning regimen choice (n = 44, 32%), and post-HCT complications after day 100 (n = 43, 31%). The ASBMT CCF is a successful tool for collaborative discussion of complex cases in the HCT community worldwide and may allow identification of areas of controversy or unmet need from clinical, educational and research perspectives

Patients’ and family caregivers’ experiences with a newly implemented hospital at home program in British Columbia, Canada: Preliminary results

The Hospital at Home (HaH) model of care, which enables the provision of acute-level care in the patient’s own home as an alternative to brick and mortar hospital admission, was introduced in British Columbia, Canada in November 2020, starting with 9 inpatient “beds” in the community. The AT-HOME research group applied a patient-oriented approach to evaluate the patients’ and family caregivers’ (FCGs) experiences with the program as it was implemented and expanded throughout Victoria, BC. In this paper, we discuss the development of the survey instruments, including process and timelines (three phases); and present preliminary findings of the observational research study (six months of patient and FCG feedback data). The preliminary results show that 100% of patients (n=75) and 95% of FCGs (n=57) had an overall positive experience with the program (rated 6-10 on a 10-point scale where 0 meant ‘very poor’ and 10 ‘very good’). 100% of these patients and 96% of these FCGs would recommend the program to their friends and family and 97% of these patients and 96% of these FCGs would choose the program again if faced with the same situation. The preliminary results on metrics pertaining to care quality; information sharing and experiences with the admission and discharge processes; FCG’s roles, medication management, and more are discussed here. The final results of the patient and FCG experiences will be reported at the end of the data collection period. We can conclude that this new HaH program has been positively received by patients and FCGs thus far and they support program expansion Experience Framework This article is associated with the Innovation & Technology lens of The Beryl Institute Experience Framework (https://www.theberylinstitute.org/ExperienceFramework).

Engaging patients and families in developing, implementing, and evaluating hospital at home: A Canadian case study

The Hospital at Home (HaH) care model is naturally patient-centred, with improved patient and family experiences and outcomes firmly anchoring the innovative approach to care. Existing literature focuses largely on the health care and patient care outcomes of HaH; however, to date, none of the identified literature has reported on engaging patients and families in the development, implementation, or evaluation of the HaH model of care. A multi-stakeholder, Patient-Oriented Research team in Victoria, British Columbia, Canada engaged patients and family/friend caregivers (PFCs) across all components of the HaH program. Guided by best practices in patient and public engagement, the team collaborated to 1) explore the potential impact of in-home acute care on PFCs’ experiences; 2) identify health, social, and practice outcomes that matter to PFCs; 3) examine the social and environmental factors which may impact delivery of HaH; and 4) inform the HaH evaluation framework that includes PFC priority measures related to experience and outcomes. A public, online survey (n=543 PFC respondents) revealed both program-specific and evaluation-specific themes. These included a focus on patients achieving their own health goals and standard health outcomes, as well as patients and caregivers receiving training to support care at home. Engaging PFCs throughout HaH conception and implementation ensured the end program accurately reflected the priorities, concerns, and values of those that HaH is meant to serve.

Blood pressure trajectory of inpatient stroke rehabilitation patients from the Determining Optimal Post-Stroke Exercise (DOSE) trial over the first 12 months post-stroke

BackgroundHigh blood pressure (BP) is the primary risk factor for recurrent strokes. Despite established clinical guidelines, some stroke survivors exhibit uncontrolled BP over the first 12 months post-stroke. Furthermore, research on BP trajectories in stroke survivors admitted to inpatient rehabilitation hospitals is limited. Exercise is recommended to reduce BP after stroke. However, the effect of high repetition gait training at aerobic intensities (&gt;40% heart rate reserve; HRR) during inpatient rehabilitation on BP is unclear. We aimed to determine the effect of an aerobic gait training intervention on BP trajectory over the first 12 months post-stroke.MethodsThis is a secondary analysis of the Determining Optimal Post-Stroke Exercise (DOSE) trial. Participants with stroke admitted to inpatient rehabilitation hospitals were recruited and randomized to usual care (n = 24), DOSE1 (n = 25; &gt;2,000 steps, 40–60% HRR for &gt;30 min/session, 20 sessions over 4 weeks), or DOSE2 (n = 25; additional DOSE1 session/day) groups. Resting BP [systolic (SBP) and diastolic (DBP)] was measured at baseline (inpatient rehabilitation admission), post-intervention (near inpatient discharge), 6- and 12-month post-stroke. Linear mixed-effects models were used to examine the effects of group and time (weeks post-stroke) on SBP, DBP and hypertension (≥140/90 mmHg; ≥130/80 mmHg, if diabetic), controlling for age, stroke type, and baseline history of hypertension.ResultsNo effect of intervention group on SBP, DBP, or hypertension was observed. BP increased from baseline to 12-month post-stroke for SBP (from [mean ± standard deviation] 121.8 ± 15.0 to 131.8 ± 17.8 mmHg) and for DBP (74.4 ± 9.8 to 78.5 ± 10.1 mmHg). The proportion of hypertensive participants increased from 20.8% (n = 15/72) to 32.8% (n = 19/58). These increases in BP were statistically significant: an effect [estimation (95%CI), value of p] of time was observed on SBP [0.19 (0.12–0.26) mmHg/week, p &lt; 0.001], DBP [0.09 (0.05–0.14) mmHg/week, p &lt; 0.001], and hypertension [OR (95%CI): 1.03 (1.01–1.05), p = 0.010]. A baseline history of hypertension was associated with higher SBP by 13.45 (8.73–18.17) mmHg, higher DBP by 5.57 (2.02–9.12) mmHg, and 42.22 (6.60–270.08) times the odds of being hypertensive at each timepoint, compared to those without.ConclusionBlood pressure increased after inpatient rehabilitation over the first 12 months post-stroke, especially among those with a history of hypertension. The 4-week aerobic gait training intervention did not influence this trajectory
