Building Healthy Places with People and for People: Community Engagement for Healthy and Sustainable Communities

Over a 25 year period, residents of the El Sereno  community in Los Angeles have opposed efforts of  investors seeking to build luxury homes on the area  known as Elephant Hill.  After years of community  organizing—canvassing door to door, developing a  broad-based coalition and mobilizing supporters to  attend public hearings—residents declared victory after  the City Council agreed to settle a lawsuit with the  developers by buying the 20-acre site for $6 million to  create a future park.  Residents are glad that a chunk of one of Los Angeles' last undeveloped hillsides  will remain open space in this park poor, working-class Latino community.  Opposition efforts reignited  in 2004 not only to preserve open space, but also to encourage public safety and counter threats to  gentrification.  Elva Yañez, the El Sereno resident who led the most recent efforts to preserve Elephant  Hill, hailed the settlement as a victory for environmental justice: "After a long and hard fought struggle,  the residents of this community have been afforded the environmental protections that are rightfully theirs.   We are pleased that this poorly planned project is not moving forward and environmental justice has  prevailed."

Geometry and electronic structure of iridium adsorbed on graphene

We report investigation of the geometry and electronic structure of iridium atoms adsorbed onto graphene through a combined experimental and theoretical study. Ir atoms were deposited onto a flake of graphene on a Pt(111) surface and found to form clusters even at low temperatures. The areal density of the observed clusters on the graphene flake suggests the clusters are most likely pairs of Ir atoms. Theoretical ab initio density functional (DFT) calculations indicate that these Ir dimers are oriented horizontally, near neighboring "bridge" sites of the graphene lattice, as this configuration has the strongest adsorption energy of all high-symmetry configurations for the Ir dimer. A large peak in the local density of states (LDOS) at the Dirac point energy was measured via scanning tunneling spectroscopy, and this result is reproduced by a DFT calculation of the LDOS. The peak at the Dirac point energy is found to be from the Ir s and p states. The LDOS in the monomer case was also calculated, and is found to significantly differ from the experimentally determined data, further supporting the hypothesis of low-temperature clustering

Promoting Health Literacy through Leading Edge Occupational Therapy Education

Synopsis: Health literacy has become a vital focus of U.S. healthcare. By incorporating health literacy knowledge, attitudes, and skills into entry-­‐level education, occupational therapy professionals can enact a leading role in health and human services teams to address our national healthcare goals.

The structure of a resuscitation-promoting factor domain from Mycobacterium tuberculosis shows homology to lysozymes

Resuscitation-promoting factor (RPF) proteins reactivate stationary-phase cultures of (G+C)-rich Gram-positive bacteria including the causative agent of tuberculosis, Mycobacterium tuberculosis. We report the solution structure of the RPF domain from M. tuberculosis Rv1009 (RpfB) solved by heteronuclear multidimensional NMR. Structural homology with various glycoside hydrolases suggested that RpfB cleaved oligosaccharides. Biochemical studies indicate that a conserved active site glutamate is important for resuscitation activity. These data, as well as the presence of a clear binding pocket for a large molecule, indicate that oligosaccharide cleavage is probably the signal for revival from dormancy

Mental health first aid training in a workplace setting: A randomized controlled trial [ISRCTN13249129]

BACKGROUND: The Mental Health First Aid training course was favorably evaluated in an uncontrolled trial in 2002 showing improvements in participants' mental health literacy, including knowledge, stigmatizing attitudes, confidence and help provided to others. This article reports the first randomized controlled trial of this course. METHODS: Data are reported on 301 participants randomized to either participate immediately in a course or to be wait-listed for 5 months before undertaking the training. The participants were employees in two large government departments in Canberra, Australia, where the courses were conducted during participants' work time. Data were analyzed according to an intention-to-treat approach. RESULTS: The trial found a number of benefits from this training course, including greater confidence in providing help to others, greater likelihood of advising people to seek professional help, improved concordance with health professionals about treatments, and decreased stigmatizing attitudes. An additional unexpected but exciting finding was an improvement in the mental health of the participants themselves. CONCLUSIONS: The Mental Health First Aid training has shown itself to be not only an effective way to improve participants' mental health literacy but also to improve their own mental health. It is a course that has high applicability across the community

Self-Affirmation Improves Problem-Solving under Stress

High levels of acute and chronic stress are known to impair problem-solving and creativity on a broad range of tasks. Despite this evidence, we know little about protective factors for mitigating the deleterious effects of stress on problem-solving. Building on previous research showing that self-affirmation can buffer stress, we tested whether an experimental manipulation of self-affirmation improves problem-solving performance in chronically stressed participants. Eighty undergraduates indicated their perceived chronic stress over the previous month and were randomly assigned to either a self-affirmation or control condition. They then completed 30 difficult remote associate problem-solving items under time pressure in front of an evaluator. Results showed that self-affirmation improved problem-solving performance in underperforming chronically stressed individuals. This research suggests a novel means for boosting problem-solving under stress and may have important implications for understanding how self-affirmation boosts academic achievement in school settings. © 2013 Creswell et al

Toward Establishing Integrated, Comprehensive, and Sustainable Meningitis Surveillance in Africa to Better Inform Vaccination Strategies

Large populations across sub-Saharan Africa remain at risk of devastating acute bacterial meningitis epidemics and endemic disease. Meningitis surveillance is a cornerstone of disease control, essential for describing temporal changes in disease epidemiology, the rapid detection of outbreaks, guiding vaccine introduction and monitoring vaccine impact. However, meningitis surveillance in most African countries is weak, undermined by parallel surveillance systems with little to no synergy and limited laboratory capacity. African countries need to implement comprehensive meningitis surveillance systems to adapt to the rapidly changing disease trends and vaccine landscapes. The World Health Organization and partners have developed a new investment case to restructure vaccine-preventable disease surveillance. With this new structure, countries will establish comprehensive and sustainable meningitis surveillance systems integrated with greater harmonization between population-based and sentinel surveillance systems. There will also be stronger linkage with existing surveillance systems for vaccine-preventable diseases, such as polio, measles, yellow fever, and rotavirus, as well as with other epidemic-prone diseases to leverage their infrastructure, transport systems, equipment, human resources and funding. The implementation of these concepts is currently being piloted in a few countries in sub-Saharan Africa with support from the World Health Organization and other partners. African countries need to take urgent action to improve synergies and coordination between different surveillance systems to set joint priorities that will inform action to control devastating acute bacterial meningitis effectively

The Impact of Student Hotspotting on Patients & the Jefferson Health System

Introduction “Super-utilizers”, patients with five or more hospital admissions in the past year, account for half of all healthcare expenditures and present a significant financial burden to our healthcare system. In Pennsylvania “super-utilizers” result in $1.25 billion of healthcare spending and Philadelphia has the highest number of “super-utilizers” in the state. To address this crisis, Jefferson University serves as one of four new national hubs for student hotspotting. Teams of interprofessional health professions students along with faculty and staff advisors enroll “super-utilizers” and provide targeted interventions to address social determinants of health, reduce hospitalizations and improve patient outcomes. Methods To examine the impact of this program on patients, objective healthcare outcomes were obtained from EPIC. Costs were obtained from the hospital Care Coordination team and national average figures to examine the impact on the Jefferson health system. Data were collected from six months pre-, during, and post-intervention for the hotspotting intervention group and for a matched control group of non-program participants. Pre- and post-intervention analysis was performed using random effects Poisson regression. Results Pre- and post-intervention analysis found a 6% reduction in ED visits, 48% reduction in the number of outpatient visits, 18% reduction in total days in hospital, and 14% reduction in 30 day readmissions for the intervention vs. the control group. Average total costs of care decreased for both the experimental and control group with a 36% cost reduction per patient in the intervention group. Conclusion Participation in student hotspotting is a promising way to help address the needs of “super-utilizes”. Student hotspotting appears to have a positive impact on reducing the costs of care and improving health outcomes for high utilizer patients
