Skeletal muscle mitochondrial energetics are associated with maximal aerobic capacity and walking speed in older adults.

BACKGROUND: Lower ambulatory performance with aging may be related to a reduced oxidative capacity within skeletal muscle. This study examined the associations between skeletal muscle mitochondrial capacity and efficiency with walking performance in a group of older adults. METHODS: Thirty-seven older adults (mean age 78 years; 21 men and 16 women) completed an aerobic capacity (VO peak) test and measurement of preferred walking speed over 400 m. Maximal coupled (State 3; St3) mitochondrial respiration was determined by high-resolution respirometry in saponin-permeabilized myofibers obtained from percutanous biopsies of vastus lateralis (n = 22). Maximal phosphorylation capacity (ATP) of vastus lateralis was determined in vivo by P magnetic resonance spectroscopy (n = 30). Quadriceps contractile volume was determined by magnetic resonance imaging. Mitochondrial efficiency (max ATP production/max O consumption) was characterized using ATP per St3 respiration (ATP/St3). RESULTS: In vitro St3 respiration was significantly correlated with in vivo ATP (r = .47, p = .004). Total oxidative capacity of the quadriceps (St3*quadriceps contractile volume) was a determinant of VO peak (r = .33, p = .006). ATP (r = .158, p = .03) and VO peak (r = .475, p < .0001) were correlated with preferred walking speed. Inclusion of both ATP/St3 and VO peak in a multiple linear regression model improved the prediction of preferred walking speed (r = .647, p < .0001), suggesting that mitochondrial efficiency is an important determinant for preferred walking speed. CONCLUSIONS: Lower mitochondrial capacity and efficiency were both associated with slower walking speed within a group of older participants with a wide range of function. In addition to aerobic capacity, lower mitochondrial capacity and efficiency likely play roles in slowing gait speed with age.

1009-004 Lost Island Lake Watershed Final Report

The Lost Island Lake watershed is located in the prairie pothole region, a region dotted with glacial wetlands and shallow lakes. At 1,180 acres, Lost Island Lake is the state's fifth largest natural lake and its watershed is comprised of nearly 1,000 acres of wetland habitat, including Iowa 's largest natural wetland – Barringer Slough. Unfortunately, Lost Island and its associated wetlands are not functioning to their fullest ecological and water quality potential. In 2002 and 2004, Lost Island Lake was categorized as '·impaired'" on Iowa's Impaired Waters List. Frequent algal blooms and suspended solids drastically increase turbidity levels resulting in its impairment. To investigate these concerns, a two-year study and resulting Water Quality Improvement Plan were completed. The water quality study identified an overabundance of non-native common carp (Cyprinus carpio) in the lake and its surrounding wetlands as a primary cause of impairment. The goal of the Lost Island Lake Watershed Enhancement Project is to restore ecological health to Lost Island Lake and its intricate watershed resulting in improved water quality and a diverse native plant and wildlife community. The purpose of this grant is to obtain funding for the construction of two combination fish barriers and water control structures placed at key locations in the watershed within the Blue Wing Marsh complex. Construction of the fish barriers and water control structures would aid restoration efforts by preventing spawning common carp from entering wetlands in the watershed and establishing the ability to manage water levels in large wetland areas. Water level management is crucial in wetland health and exotic fish control. These two structures are part of a larger construction project that involves a total of four combination fish barriers and water control structures and one additional fish barrier. The entire Lost Island Lake Watershed Enhancement Project is a multi-year project, but the construction phase for the fish barriers and water control structures will be completed before December 31, 2011.

07013-004 Rathbun Lake Watershed Final Report

The Rathbun Land and Water Alliance and partners have implemented a uniquely effective approach to water quality protection through the Rathbun Lake Special Project. This approach is achieving a significant reduction in the sediment and phosphorus that impair water quality in Rathbun Lake and its tributaries as a result of the targeted application of best management practices (BMPs) for priority land in the watershed. This project application proposes to assist landowners to apply BMPs that will reduce sediment and phosphorus delivery from priority land in four targeted sub-watersheds as part of the Rathbun Lake Special Project. Features of this project are: (1) use of geographic information system (GIS) analysis to identify priority land that requires BMPs; (2) assistance for landowners to apply BMPs on 5,100 acres that will reduce the annual delivery of sediment by 8,130 tons and phosphorus by 35,980 pounds; (3) evaluation of the benefits from BMP application using GIS analysis and water quality monitoring; and (4) watershed outreach activities that encourage landowners to apply BMPs for priority land to protect water quality.

06009-004 Price Creek Watershed Final Report

Price Creek is a 13 mile long stream located in SE Benton County and the NE corner of Iowa County. It ends below the village of Amana where it flows into the Iowa River. The Iowa and Benton County Soil & Water Conservation Districts (SWCDs) applied (and were tentatively approved) for 319/WPF/WSPF funding to treat livestock and water quality issues in this watershed over the next three years. That project’s funds were allocated for a Project Coordinator, information and education activities, and cost share for Best Management Practices (BMPs) directed toward livestock issues and nutrient issues. Soil erosion and sedimentation are also problems in this 18,838 acre watershed. It is 64% HEL (highly erodible land) and 58% of it is cropped. With a coordinator working with Price Creek producers, this would be an excellent time to also address the soil loss and sedimentation issues in this watershed. We will offer additional cost share incentives on BMPs targeting soil erosion on the critical areas we’ve identified. We are applying to IWIRB for additional funding to allow us to cost share specific BMPs up to 75% to treat soil loss in these critical areas of the Price Creek Watershed.

05008-004 Mill-Picayune (Manteno Lake) Watershed Final Report

Manteno Lake is located 8 miles northwest of Earling, IA in Shelby County. The lake has been impaired with an overload of silt and nutrients. In October of 2007, land directly north of the lake will be coming out of CRP and back into agricultural production. The Shelby Soil and Water Conservation District, Shelby County Board of Supervisors and Shelby County Conservation Board feel strongly that treatment of this area is necessary prior to the CRP contract expiring. The placement and construction of three structures will reduce the amount of silt and nutrients affecting Manteno Lake. This project calls for the construction of three structures on crucial tributaries to the lake.

2012 Iowa Small Hospital Improvement Program (SHIP) Briefing and Survey Report, January 22, 2013

In August of 2012 the Iowa State Office of Rural Health (SORH) conducted a survey to determine the value of the Small Rural Hospital Improvement Program (SHIP) in Iowa. This survey was distributed to the 84 participating hospitals however, because some hospitals network their SHIP funds we only asked the contract administrators of the contracts to complete the survey. 58 of the 78 SHIP contract administrators completed the survey (74%). Background: SHIP brings in roughly $750,000.00 annually to Iowa to assist small Iowa hospitals. Average distribution of approximately $7,500 per hospital. Seventy three of ninety nine Iowa counties are represented.

Iowa Comprehensive Heart Disease and Stroke Plan, 2010-2014, March 22, 2010

Heart disease is the number one cause of death for both men and women nationally as well as in the state of Iowa, while stroke is the third leading cause of death. These two diseases are often grouped together under the broader term ―cardiovascular disease‖ (CVD), which accounts for one-third of all deaths within the state. Ongoing efforts to increase prevention of, and improve care for, those who experience CVD have resulted in a decline in the number of deaths in Iowa caused by these conditions. In 1991, the death rate as a result of cardiovascular disease was 344.9 per 100,000 people; by 2006, that number had fallen to 239.9. Deaths as a result of stroke have also dropped, from 74.7 in 1991 to 57.4 in 2006.1 Although progress has been made; these illnesses are still major causes of death and serious disability for many Iowans. Despite the fact that some progress has been made through past efforts, current data show that the journey must continue to achieve the long, quality filled lives that Iowans deserve, free of chronic disease. Up to this point, there has been a lack of involvement by stakeholders against heart disease and stroke in Iowa. Causes of CVD are largely known and preventable, and more must be done to educate and spread this information throughout the state. This comprehensive statewide plan is a call to action to improve prevention, treatment, and management of heart disease and stroke in Iowa. Through the commitment and collaborative efforts of many, the Iowa Comprehensive Heart Disease and Stroke Plan 2010-2014 provides a guide to improve the health status of all Iowans. The people of Iowa have a long history of working together to do the right thing. We must rise to the challenge of lowering the incidence of heart disease and stroke through early and ongoing education that stresses prevention and healthy lifestyle choices, medical services that provide evidence-based, effective treatment and long term care management without disparity, and environmental policies that support the prevention of heart disease and stroke in our schools, work sites, and communities. This strategic plan is a guide to improving cardiovascular health in Iowa through 2014.

Assessment of panobacumab as adjunctive immunotherapy for the treatment of nosocomial Pseudomonas aeruginosa pneumonia.

The fully human anti-lipopolysaccharide (LPS) immunoglobulin M (IgM) monoclonal antibody panobacumab was developed as an adjunctive immunotherapy for the treatment of O11 serotype Pseudomonas aeruginosa infections. We evaluated the potential clinical efficacy of panobacumab in the treatment of nosocomial pneumonia. We performed a post-hoc analysis of a multicenter phase IIa trial (NCT00851435) designed to prospectively evaluate the safety and pharmacokinetics of panobacumab. Patients treated with panobacumab (n = 17), including 13 patients receiving the full treatment (three doses of 1.2 mg/kg), were compared to 14 patients who did not receive the antibody. Overall, the 17 patients receiving panobacumab were more ill. They were an average of 72 years old [interquartile range (IQR): 64-79] versus an average of 50 years old (IQR: 30-73) (p = 0.024) and had Acute Physiology and Chronic Health Evaluation II (APACHE II) scores of 17 (IQR: 16-22) versus 15 (IQR: 10-19) (p = 0.043). Adjunctive immunotherapy resulted in an improved clinical outcome in the group receiving the full three-course panobacumab treatment, with a resolution rate of 85 % (11/13) versus 64 % (9/14) (p = 0.048). The Kaplan-Meier survival curve showed a statistically significantly shorter time to clinical resolution in this group of patients (8.0 [IQR: 7.0-11.5] versus 18.5 [IQR: 8-30] days in those who did not receive the antibody; p = 0.004). Panobacumab adjunctive immunotherapy may improve clinical outcome in a shorter time if patients receive the full treatment (three doses). These preliminary results suggest that passive immunotherapy targeting LPS may be a complementary strategy for the treatment of nosocomial O11 P. aeruginosa pneumonia.
