Cognitive Strategies During Moderate-Intensity Running: Psychologicaland Performance Outcomes in Non-Elite Runners

Cognitive strategies allow athletes and recreational exercisers to shift their focus of attention to achieve psychological benefits and performance enhancements. The types of cognitive strategy utilized, association and dissociation, can differentially affect individuals’ psychological and performance outcomes. The purpose of the current study was to examine the potential relationships between cognitive strategies and enjoyment, mood, time to completion, heart rate, perceived exertion, and self-efficacy by randomly assigning participants to two interventions: an Association intervention and a Dissociation intervention. Participants (N = 12) included male, college-age recreational exercisers who exercised for at least 120 minutes per week in the previous month. Participants completed two 1.5-mile jogging sessions under both the Associative and Dissociative interventions. During the exercise, heart rate and ratings of perceived exertion were recorded every four laps, and time to completion and state enjoyment were recorded following the completion of the run. Self-efficacy and mood states were measured pre- and post-exercise. No evidence was produced to indicate that state enjoyment was influenced by the interventions (i.e., cognitive strategies). When using the Association intervention first, there was a main effect for Depression between Association and Dissociation; however, this result was independent of Time. When using the Dissociation intervention first, the participants’ mood states of Fatigue and Confusion were found to decrease while Vigor increased, but only during the dissociation intervention. Time to completion, heart rate, ratings of perceived exertion, and task or scheduling self-efficacy were not significantly influenced by the type cognitive strategy used; however, participants did report increases in RPE over time and increases in coping self-efficacy pre- to post-exercise. It was concluded that the cognitive strategy intervention, independent of order, did not directly influence any dependent variables. Nonetheless, following a 20-minute exercise, male recreational exercisers were able to enhance positive psychological outcomes. Future research should examine various modes and intensities of exercise as well as participants’ preferred exercise to further study the use of cognitive strategies during exercise

Decoding the Gut Microbiome; Providing Solutions for Poultry Production

The term “microbiome” refers to all the micro-organisms within a particular environment. In poultry, the microbiome is influenced by the barn, diet, and age of the birds and is believed to modulate immunity and inflammation. In the past, culture methods were primarily used to evaluate the presence of the various micro-organisms present in the microbiome; however, recent technological advances in genomic sequencing have revolutionized sample analysis. This technology has opened new avenues of research in poultry production and our understanding of the associated health challenges. Turkey cellulitis has been a major economic and health concern for many years. Traditional bacterial culture methods indicate that multiple species may be involved in this disease with most studies implicating either Clostridium septicum or Clostridium perfringens as the primary pathogens. A recent study by Luisa de Oliveira et al. indicates that avian pathogenic Escherichia coli may also play an important role in the development of cellulitis. The purpose of this presentation is to share the results of a study conducted to further understand the microbiome of turkeys with cellulitis

A Randomized Trial Evaluating a Parent Based Intervention to Reduce College Drinking

This study evaluated the effectiveness of a parent based intervention (PBI) in reducing drinking among first year college students (N = 443). Students were assigned to one of three conditions: PBI, PBI plus booster brochures (PBI-B), and an assessment only control group (CNT). At a 4-month post-intervention follow-up, results indicated students in the PBI-B group reported significantly less drinking to intoxication and peak drinking relative to the PBI group and CNT group. No significant differences were found between the PBI group and CNT group. Results provide further support for PBIs to reduce college student drinking and suggest that a booster brochure increases the effectiveness of PBIs

Survival and Growth of Three Geographically Distinct Stocks of Muskellunge Introduced into Midwestern Reservoirs

Muskellunge Esox masquinongy management programs often rely on stocking to create and maintain populations. In many instances, a native and nearby stocking source is unavailable or a genetically suitable brood source is unclear. Genetic differences among stocks of Muskellunge may influence survival and growth when introduced into novel environments. Consequently, the selection of a suitable brood source can be difficult and possibly critical to the success of Muskellunge stocking programs. We examined differences in long-term survival and growth among introduced Muskellunge stocks from the Ohio and upper Mississippi River drainages and a mixed-origin Illinois broodstock population in three Illinois reservoirs. Catch per unit effort (CPUE) from spring modified-fyke netting suggested that the upper Mississippi River drainage stock at ages 3 and 4 persisted at lower relative abundance compared to conspecifics; however, low lake- and stock-specific catches of older ages precluded robust CPUE comparisons among stocks. Apparent survival, estimated from mark-recapture data with the Cormack-Jolly-Seber open population model, differed among stocks I-year poststocking, with the upper Mississippi River drainage stock exhibiting markedly lower survival compared to conspecifics. Annual variation in survival to age 1.5 was related to water temperature at stocking, fish size at stocking, first winter temperatures, and first summer temperatures. However, survival did not differ among stocks for Muskellunge age 2 and older, indicating that important factors structuring long-term survival exert their effects most strongly in the first year poststocking. Despite overall low survival of Muskellunge from the upper Mississippi River drainage, males that survived exhibited a slight growth advantage compared to conspecifics. No growth advantage was observed for upper Mississippi River drainage stock females. Our findings suggest that stock selection in addition to environmental conditions can influence survival of introduced Muskellunge and subsequent contribution to the fishery

Air Toxics Under The Big Sky – A High School Science Teaching Tool

A project has been developed between Big Sky High School and The University of Montana (UM) which has brought together high school students and teachers, university scientists, and county environmental health officials in a multilayered research experience focusing on the collection and analysis of specific air toxics, and investigating their relationship to respiratory diseases. The Air Toxics Under the Big Sky project allows students to benefit from an independent experience linking science, research, and local environmental issues. We see this as a long term project which will be built upon and expanded by future students during each new school year and as new schools are added. This project will foster a long-term scientific collaboration between UM and Montana high schools, and establishes high school students as valuable contributors to the scientific community while educating them about environmental issues

Sensor recorded changes in rates of hand washing with soap in response to the media reports of the H1N1 pandemic in Britain

Objectives To examine how the frequency of information regarding a real disease threat influences hand washing with soap. Design and setting The authors installed wireless devices in highway service station lavatories in England to record the proportion of individuals washing hands with soap from May 2009 to January 2010. Participants Participants were users of men's and women's toilets. Combined there was an average of 6800 participant entrances into the lavatories daily. Primary outcome measure The primary outcome measure is the proportion of soap usage to the number of entries into the lavatories. Results Hand-washing rates were positively related to both H1NI coverage in blogs and the news; however, these relationships were stronger for men than for women. Conclusions Hand washing with soap increases proportionally to the frequency of media key words related to H1N1. Women's hand washing was more strongly associated with incidence of media keywords than men's

Fucose Sensing Regulates Bacterial Intestinal Colonization

The mammalian gastrointestinal (GI) tract provides a complex and competitive environment for the microbiota1. Successful colonization by pathogens depends on scavenging nutrients, sensing chemical signals, competing with the resident bacteria, and precisely regulating expression of virulence genes2. The GI pathogen enterohemorrhagic E.coli (EHEC) relies on inter-kingdom chemical sensing systems to regulate virulence gene expression3–4. Here we show that these systems control the expression of a novel two-component signal transduction system, named FusKR, where FusK is the histidine sensor kinase (HK), and FusR the response regulator (RR). FusK senses fucose and controls expression of virulence and metabolic genes. This fucose-sensing system is required for robust EHEC colonization of the mammalian intestine. Fucose is highly abundant in the intestine5. Bacteroides thetaiotaomicron (B.theta) produces multiple fucosidases that cleave fucose from host glycans, resulting in high fucose availability in the gut lumen6. During growth in mucin, B.theta contributes to EHEC virulence by cleaving fucose from mucin, thereby activating the FusKR signaling cascade, modulating EHEC’s virulence gene expression. Our findings suggest that EHEC uses fucose, a host-derived signal made available by the microbiota, to modulate EHEC pathogenicity and metabolism

Diabetes Self-Management Education and Support: Referral and Attendance at a Patient-Centered Medical Home

Background: Although evidence shows that diabetes self-management education and support (DSMES) is an effective tool to help individuals with type 2 diabetes (T2DM) improve their health outcomes, there remains a large number of individuals not attending DSMES. Understanding how frequently patients receive referrals to DSMES and the number of DSMES hours they receive is important to determine, as well as patients' health outcomes of utilizing DSMES. This will help us understand patterns of utilization and the outcomes that occur when such a valuable resource is utilized. Methods: Secondary data analysis was conducted of patient electronic medical records at a primary healthcare federally qualified clinic and 2 area hospitals. We identified 105 adult patients with a new T2DM diagnosis with at least 2 A1c lab results 3 to 12 months apart during the study period. Results: Only 53.5% were referred to DSMES. Out of those who were referred, 66% received no DSMES, 17% received 1-hour assessment, 4% received partial DSMES, and 13% received 8 or more hours. Linear regression of percent change in A1c and number of DSMES hours received, revealed that receiving 1 (P =.001) or 8 or more hours of DSMES (P =.022) had a significant negative relationship with the percent difference in A1c compared to the group who received no DSMES. Patients who had an hour of assessment had a similar percent reduction in A1c to those who had partial DSMES. Conclusion: Referral rates and enrollment in DSMES remain low. Those who enrolled often dropped out after the one-hour assessment session. Results suggest making the one-hour assessment session more educationally comprehensive or longer to retain patients. Improving the DSMES referral process and further investing physicians' decisions on whether to refer or not refer patients to DSMES are key for future studies.Scopu

Economic and Practical Factors in Diagnosing HNPCC Using Clinical Criteria, Immunohistochemistry and Microsatellite Instability Analysis

Aim: To determine a cost-efficient strategy for HNPCC molecular diagnostic testing. Methods: 138 families referred to a Regional Genetics Service had hMLH1 and hMSH2 mutation analysis. The sensitivity and specificity of clinical selection criteria with or without immunohistochemistry (IHC) and microsatellite instability (MSI) analysis to further refine case selection and the effect of these approaches on the cost of mutation analysis were examined. Results: Clearly deleterious mutations were identified in 49/138 (35.5%) of all families tested. The most sensitive criteria for identifying families with MMR mutations were the full Bethesda guidelines but these have poor specificity. IHC and MSI were useful pre-screening tools. Conclusion: A cost-efficient approach in laboratories where IHC and/or MSI analysis are available, is to use inclusive (non-specific) criteria to select cases, followed by IHC and then MSI. Where one or both results are abnormal, proceed to further mutation analysis. Where MSI or IHC or tumour blocks are not available, more restrictive clinical criteria may be more appropriate for cost-efficient case selection

Ground-Penetrating Radar Evaluation of Moisture and Frost across Typical Saskatchewan Road Soils

This study was undertaken to evaluate the effect of soil type, moisture content, and the presence of frost on road substructure permittivity. Permittivity sensitivity of typical road soils was characterized in the laboratory to provide baseline dielectric constant values which were compared to field ground penetrating radar (GPR) survey results. Both laboratory devices, the complex dielectric network analyzer and the Adek Percometer, as well as the field GPR system were used in this study to measure the dielectric constant of soils. All three systems differentiated between coarse-grained and fine grained soils. In addition, at temperatures below freezing, all three systems identified an increase in water content in soils; however, when frozen, the sensitivity of dielectric constant across soil type and moisture content was significantly reduced. Based on the findings of this study, GPR technology has the ability to characterize in situ substructure soil type and moisture content of typical Saskatchewan road substructure soils. Given the influence of road soil type and moisture content on in-service road performance, this ability could provide road engineers with accurate estimates of in situ structural condition of road structures for preservation and rehabilitation planning and optimization purposes
