Functional Cognition: An Opportunity to Highlight the Role of Occupational Therapy in Post-Concussion Care

As concern surrounding concussion and the associated long-term effects grow, a continued need for comprehensive, holistic concussion care emerges. Occupational therapists are well-equipped to address the wide variety of symptoms and deficits that clients may experience post-concussion. Functional cognition is one area in which occupational therapists can demonstrate their unique value on the interdisciplinary treatment team. In this Opinions in the Profession paper, we describe how occupational therapists are poised to further establish their role in post-concussion care by becoming the primary discipline for assessing and treating functional cognition. The aim of this paper is to outline the role of occupational therapy in post-concussion care in regard to becoming the primary discipline for assessing and treating functional cognition and distinguishing occupational therapists as experts in functional cognition. Implications for practice, education, and research are discussed

Effects of Yoga on Perceived Stress Level and Cognitive Ability in College-Aged Females

Purpose: The purpose of this study was to determine if perceived stress levels and response inhibition scores (measure of cognitive function) differ in female college students who regularly participate in yoga compared to female college students who do not. Methods: College-aged females ranging from 19-24 years of age were recruited to participate in this study. Subjects filled out a personal information sheet followed by a perceived stress level questionnaire to measure the amount of yoga each participant performed and assess their perceived stress level, respectively. Response inhibition and accuracy (cognitive function) were measured via a computerized Stroop Effect test consisting of three modules. The research project implemented a cross-sectional design, with the independent variable being past yoga experience (no previous experience & regular yoga participation) and the dependent variables being perceived stress level and response inhibition (speed & accuracy) score of the Stroop Effect test. Significance was accepted at p ≤0.05. Results: An independent t-test revealed that there were no differences in average reaction time or percent accuracy between yogis and novice yogis. The difference between average perceived stress scores (PSS) in advanced versus novice yogis was approaching significance (p ≤ 0.06). The PSS for novice yogis was 17.28 ± 4.20 while that for advanced yogis was 21.59 ± 7.96. Conclusion: The study concludes that yogis reported higher PSS compared to non-yogis; however, there was no significant difference in cognitive ability between the groups. Future studies should seek to further investigate various measures of cognitive abilities in these populations. Furthermore, more research should be implemented to discern the true effects of yoga on an individual’s perceived stress level

Learning Community Psychology Practice Competencies: Student Pathways through the Applied Community Psychology Specialization

Community psychology practice competencies provide a framework of skills students can learn to promote social change processes in communities. However, there is great overlap and cross-over of skill sets among some competencies. The complex nature of learning any competency will likely take multiple learning experiences to master and span years beyond a student’s exit from training to achieve expertise. Programs training students in practice competencies can benefit from working collaboratively with students to better understand how students develop experience and skill in utilizing competencies across the curriculum. This article explores five narrative accounts of how students and graduates learned selected community psychology practice competencies through their training in the Applied Community Psychology (ACP) specialization at Antioch University Los Angeles. Students and graduates were asked to select a competency and write a two-page narrative of how they learned the competency through their training in the ACP specialization. Implications for academic program development and training in community psychology practice competencies are discussed

Tissue Tropism in Host Transcriptional Response to Members of the Bovine Respiratory Disease Complex.

Bovine respiratory disease (BRD) is the most common infectious disease of beef and dairy cattle and is characterized by a complex infectious etiology that includes a variety of viral and bacterial pathogens. We examined the global changes in mRNA abundance in healthy lung and lung lesions and in the lymphoid tissues bronchial lymph node, retropharyngeal lymph node, nasopharyngeal lymph node and pharyngeal tonsil collected at the peak of clinical disease from beef cattle experimentally challenged with either bovine respiratory syncytial virus, infectious bovine rhinotracheitis, bovine viral diarrhea virus, Mannheimia haemolytica or Mycoplasma bovis. We identified signatures of tissue-specific transcriptional responses indicative of tropism in the coordination of host's immune tissue responses to infection by viral or bacterial infections. Furthermore, our study shows that this tissue tropism in host transcriptional response to BRD pathogens results in the activation of different networks of response genes. The differential crosstalk among genes expressed in lymphoid tissues was predicted to be orchestrated by specific immune genes that act as 'key players' within expression networks. The results of this study serve as a basis for the development of innovative therapeutic strategies and for the selection of cattle with enhanced resistance to BRD

Limited refugia and high velocity range-shifts predicted for bat communities in drought-risk areas of the Northern Hemisphere

Abstract Species occupying semi-arid and dry regions around the globe face an uncertain future due to increases in the frequency and severity of droughts. In this study we modelled the potential effect of climate change on bat communities within two high-drought risk regions of the world and assessed the magnitude and direction of the predicted shifts in climatic suitability, locating climate change refugia and identifying species at greatest risk of population declines. To do this, we compared climate suitability models for 43 species using three global climate models and three emissions scenarios for current (1950–2000) and future (2061–2080) climates within two regions where droughts are predicted to increase, the Western Palaearctic and Western North America. Our models predicted an overall reduction in bat richness with future climates. Areas projected to support high species richness in the current climate coincided with greatest predicted species loss and greatest future drought risk. For species with the potential to extend their range, high velocity range shifts would be required to keep pace with these changes, particularly in the Western Palaearctic, where additional barriers to movement include seas and areas of high human population density. Predicted refugial zones were limited and occurred in similar areas across continents (montane and high latitude with some coastal areas). The area of climate suitability was predicted to contract for around half of study species, with nine identified as species of conservation concern due to low overlap between current and future modelled ranges. The best-case scenario for bat diversity in semi-arid and dry regions in the future is likely to be reduced species richness, with many species facing rapid range expansion over challenging landscapes to access climatically suitable areas. Conservation of bats in high drought risk regions will likely depend on protection of identified refugia and networks of water sources, as well as global measures to protect biodiversity and human wellbeing, such as reduction in global carbon emissions

Estradiol and Bisphenol A Stimulate Androgen Receptor and Estrogen Receptor Gene Expression in Fetal Mouse Prostate Mesenchyme Cells

doi:10.1289/ehp.9804Hormonal alterations during development have lifelong effects on the prostate gland. Endogenous estrogens, including 17β-estradiol (E2), and synthetic estrogenic endocrine disruptors, such as bisphenol A (BPA), have similar effects on prostate development. Increasing exposure to estrogens within the low-dose, physiologic range results in permanent increases in the size and androgen responsiveness of the prostate, whereas exposure within the high-dose, pharmacologic range has the opposite effects

Low Phytoestrogen Levels in Feed Increase Fetal Serum Estradiol Resulting in the “Fetal Estrogenization Syndrome” and Obesity in CD-1 Mice

doi:10.1289/ehp.10448Although estrogenic chemicals can disrupt development of the reproductive system, there is debate about whether phytoestrogens in soy are beneficial, benign, or harmful. We compared reproductive and metabolic characteristics in male and female mice reared and maintained on non-soy low-phytoestrogen feed or soy-based high-phytoestrogen feed. Removing phytoestrogens from mouse feed produces an obese phenotype consistent with metabolic syndrome, and the associated reproductive system abnormalities are consistent with FES due to elevated endogenous fetal estradiol. Laboratory rodents may have become adapted to high-phytoestrogen intake over many generations of being fed soy-based commercial feed; removing all phytoestrogens from feed leads to alterations that could disrupt many types of biomedical research

Bisphenol A Is Released from Used Polycarbonate Animal Cages into Water at Room Temperature

doi:10.1289/ehp.5993Bisphenol A (BPA) is a monomer with estrogenic activity that is used in the production of food packaging, dental sealants, polycarbonate plastic, and many other products. The monomer has previously been reported to hydrolyze and leach from these products under high heat and alkaline conditions, and the amount of leaching increases as a function of use. We examined whether new and used polycarbonate animal cages passively release bioactive levels of BPA into water at room temperature and neutral pH. Purified water was incubated at room temperature in new polycarbonate and polysulfone cages and used (discolored) polycarbonate cages, as well as control (glass and used polypropylene) containers. The resulting water samples were characterized with gas chromatography/mass spectrometry (GC/MS) and tested for estrogenic activity using an MCF-7 human breast cancer cell proliferation assay. Significant estrogenic activity, identifiable as BPA by GC/MS (up to 310 µg/L), was released from used polycarbonate animal cages. Detectable levels of BPA were released from new polycarbonate cages (up to 0.3 µg/L) as well as new polysulfone cages (1.5 µg/L), whereas no BPA was detected in water incubated in glass and used polypropylene cages. Finally, BPA exposure as a result of being housed in used polycarbonate cages produced a 16% increase in uterine weight in prepubertal female mice relative to females housed in used polypropylene cages, although the difference was not statistically significant. Our findings suggest that laboratory animals maintained in polycarbonate and polysulfone cages are exposed to BPA via leaching, with exposure reaching the highest levels in old cages.Support during the preparation of this manuscript was provided by grants from the National Institutes of Health (CA50354) and the University of Missouri (VMFC0018) to W.V.W., NIH (ES08293 and ES11283) to F.v.S., and the U.S.G.S
