The Significance of Trauma in the Relationship between Co-Occurring Disorders and Recidivism among Participants of a Community Mental Health\u27s Jail Diversion Program

Abstract Individuals with a psychiatric diagnosis have higher levels of criminal justice involvement compared to the general population. Multiple programs have been developed through grant monies utilizing various models to allow these individuals to be linked to mental health services in the community for the treatment of symptoms which may contribute to recidivism. These programs are designed to provide an encounter with mental health professionals who collaborate with law enforcement and other agencies to intercept these individuals at various points of justice involvement and possibly prevent further entanglements with the legal system. This study explores how trauma may impact justice involvement in individuals with a psychiatric diagnosis. For the diversion program to succeed, it is essential to provide integrated, whole-health treatment to these individuals. More studies are needed to develop diversion programs and reduce recidivism rates in those with a co-occurring psychiatric diagnosis and substance use disorder and to provide education to law enforcement and community agencies to foster collaborative relationships between community mental health agencies and the legal system

Diversity in Engineering Technology Students

In the US, there are two academic pathways to a career in engineering: Engineering and Engineering Technology (ET). Engineering Technology attracts more African American and Latin American students than traditional engineering programs. Nationally, African American students are more than twice as likely to enroll in an ET program versus Engineering. We suspect it may be due to traditional Engineering programs’ requirement of higher levels of math and science classes, often lacking in under-privileged or underserved urban or rural high schools. Recently published research by the New York Equity Coalition supports this supposition. Understanding the reasons for the higher representation of these students in ET can provide insights on the background of these students for developing effective practices and programming to improve retention of this cohort. It would also provide useful information for increasing the diversity of traditional engineering programs. This paper presents initial findings from a work in progress that is part of a multi-institution study to understand the factors that influence initial matriculation into and retention in engineering technology programs

Impact of nitrogen application timing and source on nitrate leaching and crop yield

Nutrient reduction strategies were developed and are being implemented across Midwest to reduce nutrient loading to local and downstream waters. State-wide strategies developed in response to the 2008 Gulf Hypoxia Action Plan. In order to reduce nitrate-nitrogen leaching through subsurface drainage systems, the Iowa Nutrient Reduction Strategy suggests implementation of in-field management practices including nitrogen application timing, source of nitrogen fertilizer, nitrogen application rate, and use of a nitrification inhibitor. The objectives of this study were to document the effects of nitrogen application timing (fall versus spring) and source (aqua-ammonia, urea, and poly-coated urea) on nitrate-nitrogen leaching and crop yield. Field experiments were conducted at the Agricultural Drainage and Water Quality Research and Demonstration site located near Gilmore City in Pocahontas County, Iowa, from 2011 to 2015. Treatments included in this study consisted of 32 experimental plots with both phases of a corn (Zea mays L.) and soybean (Glycine max [L.] Merr.) rotation to simulate a typical cropping system for Iowa conditions. This study showed limited impact of nitrogen application timing on nitrate-nitrogen concentrations. However, five-year average annual flow-weighted nitrate-nitrogen concentration for the soybean phase with fall applied nitrogen to the previous corn crop had significantly lower nitrate levels when compared to the spring application treatment. The use of poly-coated urea as a source of nitrogen fertilizer showed some potential to reduce nitrate-nitrogen concentrations in subsurface drainage

Sensory Rooms in Schools

What are school staff\u27s (teachers, related service providers, administrators, etc.) perceptions of the utilization and efficacy of sensory rooms to support student participation in education? This study aimed to contribute to increasing the knowledge base of effective sensory room use in the school-based context. Majority of the respondents were special education teachers and school-based OTs, but according to literature, OTs should have the largest role. There was vast diversity with how the rooms were used and what equipment/supplies were within the room (most for unplanned purposes). Responses were largely positive for the impact on student behavior/emotional regulation. 15 out of 20 respondents reported that their school has set policies/procedures. Changes have occurred in the past 10 years because literature previously stated no policies/procedures were typically in place

Engineering Technology Undergraduate Students: A Survey of Demographics and Mentoring

A report published by a group of engineering technology practitioners and others interested in engineering technology called “Engineering Technology Education in the United States” was released in early 2017. The report provided recommendations of areas for further study related to engineering technology students to increase our understanding of the population. These specifically suggested focusing on the students in comparison to other students in similar and different fields of study. Following these recommendations, a team of engineering technology education researchers has been collaborating to gather information in these areas. The team obtained institutional approval and distributed two surveys throughout the United States. The first survey was directed towards undergraduate students and the other towards those who have already completed their undergraduate degrees. This paper is focused on a high-level review of the results of the undergraduate survey, with future, in-depth publications focused on the issues identified by the report. The survey was designed to address the issues described in the report focused on matriculation, retention, and graduation from engineering technology. In this case, we are examining the demographics of undergraduate engineering technology students, mentoring, and other issues that participants self-reported, as related to their peers in other STEAM (Science, Technology, Engineering, Arts and Mathematics) majors. Later work will focus more on program (2-year vs 4-year) comparisons, socioeconomic issues, and level of preparation for the various majors categorized as STEAM. This paper is not intended to provide responses to the recommendations of the National Academy of Engineering (NAE) report, but rather provide an overview of the responses to the inquiry focused on addressing this topic. The undergraduate engineering technology student subset of the STEAM survey respondents is about 68% male and 30% female. This is as expected, recognizing that engineering technology and related disciplines tend to be male dominated. The reporting students most frequently identified as white, followed by Asian and Hispanic. Most students attended a suburban, public high school and about 47% of students reported receiving no support as they prepared to attend college

Engineering Technology Graduates: A Survey of Demographics and Mentoring

Early in 2017, a team of engineering technology practitioners along with others interested in the state of engineering technology published a report entitled “Engineering Technology Education in the United States.” This report garnered a list of recommendations and things that needed to be investigated to further our understanding of this student population; specifically focusing on the students and how they relate to other students studying both similar and different material. A team of like-minded engineering technology education researchers have been working together to ascertain the answers to the findings. They prepared two surveys, obtained institutional approval, and distributed it throughout the United States. One survey was designed to query undergraduate students and the other student graduates or those who have already graduated. This paper is intended to provide a high-level review of what was found in the graduate survey, while future journal publications will take a deeper look into some of the prevailing issues identified by the report. The survey was designed to address issues described in the report as “loose coupling” of completed degrees and employment. In this case, we are examining the demographics of graduates and potential influences of their career and academic choices. Later work will focus more on salaries and other factors that influence engineering technology graduates and their lives post-graduation. Responding graduates are closely aligned to the graduate demographic with nearly 57% male and nearly 42% female. Since STEAM (Science, Technology, Engineering, Arts, and Mathematics) graduates were polled, the number is expected to be closer to par, representing the general graduate population. Most students were white, followed by Hispanic and Asian; other races are far fewer in number. Nearly 17% of the graduates began their studies in a two-year institution, and the balance at a 4-year institution. Thirty-three percent of the respondents stated they had a graduate degree. This paper will focus on the engineering technology graduate subset of the STEAM graduate survey respondents

Factors influencing resilience to postoperative delirium in adults undergoing elective orthopaedic surgery

Introduction Delirium occurs after elective arthroplasty in 17 per cent of adults1, and is associated with poor outcomes, including cognitive decline2, dementia3,4, and death5. Predisposing and precipitating risk factors accumulate and interact to precipitate delirium6. Much of the current literature analyses delirium as a dichotomous outcome, inevitably placing many people with symptoms of delirium, but falling short of a diagnosis, into the no-delirium group. Freedom from delirium symptoms should be investigated as an outcome. As evidence accumulates that delirium symptoms can also be associated with negative outcomes, it is important to identify the resilient groups in these studies and establish modifiable resilience predictors. Studies have explored risk factors for postoperative delirium; however, none to date has defined or considered delirium resilience as an outcome or phenotype. Resilience may be broadly defined as ‘the ability to withstand or recover quickly from difficult conditions’7,8. The aim of this study was to identify predictors of delirium resilience in the perioperative setting

A Comparison of Accelerated and Non-accelerated MRI Scans for Brain Volume and Boundary Shift Integral Measures of Volume Change: Evidence from the ADNI Dataset.

The aim of this study was to assess whether the use of accelerated MRI scans in place of non-accelerated scans influenced brain volume and atrophy rate measures in controls and subjects with mild cognitive impairment and Alzheimer's disease. We used data from 861 subjects at baseline, 573 subjects at 6 months and 384 subjects at 12 months from the Alzheimer's Disease Neuroimaging Initiative (ADNI). We calculated whole-brain, ventricular and hippocampal atrophy rates using the k-means boundary shift integral (BSI). Scan quality was visually assessed and the proportion of good quality accelerated and non-accelerated scans compared. We also compared MMSE scores, vascular burden and age between subjects with poor quality scans with those with good quality scans. Finally, we estimated sample size requirements for a hypothetical clinical trial when using atrophy rates from accelerated scans and non-accelerated scans. No significant differences in whole-brain, ventricular and hippocampal volumes and atrophy rates were found between accelerated and non-accelerated scans. Twice as many non-accelerated scan pairs suffered from at least some motion artefacts compared with accelerated scan pairs (p ≤ 0.001), which may influence the BSI. Subjects whose accelerated scans had significant motion had a higher mean vascular burden and age (p ≤ 0.05) whilst subjects whose non-accelerated scans had significant motion had poorer MMSE scores (p ≤ 0.05). No difference in estimated sample size requirements was found when using accelerated vs. non-accelerated scans. Accelerated scans reduce scan time and are better tolerated. Therefore it may be advantageous to use accelerated over non-accelerated scans in clinical trials that use ADNI-type protocols, especially in more cognitively impaired subjects

Neuroimaging, clinical and life course correlates of normal-appearing white matter integrity in 70-year-olds

We investigate associations between normal-appearing white matter (NAWM) microstructural integrity in cognitively normal ∼70-year-olds and concurrently measured brain health and cognition, demographics, genetics and life course cardiovascular health. Participants born in the same week in March 1946 (British 1946 Birth cohort) underwent PET-MRI around age 70. Mean standardized NAWM integrity metrics (fractional anisotropy (FA), mean diffusivity (MD), neurite density index (NDI) and orientation dispersion index (ODI)) were derived from diffusion MRI. Linear regression was used to test associations between NAWM metrics and (1) concurrent measures, including whole brain volume, white matter hyperintensity volume (WMHV), PET amyloid and cognition; (2) the influence of demographic and genetic predictors, including sex, childhood cognition, education, socioeconomic position, and genetic risk for Alzheimer’s Disease (APOE-ε4); (3) systolic and diastolic blood pressure and cardiovascular health (FHS-CVS) across adulthood. Sex interactions were tested. Statistical significance included false discovery rate correction (5%). 362 participants met inclusion criteria (mean age 70 years, 49% female). Higher WMHV was associated with lower FA (b=-0.09 [95%CI:-0.11, -0.06] p<0.01), NDI (b=-0.17 [-0.22, -0.12] p<0.01), and higher MD (b=0.14 [-0.10, -0.17] p<0.01); amyloid (in men) was associated with lower FA (b=-0.04 [-0.08, -0.01] p=0.03) and higher MD (b=0.06 [0.01,0.11] p=0.02). FHS-CVS in later-life (age 69) was associated with NAWM [lower FA (b=-0.06 [-0.09, -0.02] p<0.01), NDI (b=-0.10 [-0.17, -0.03] p<0.01), and higher MD (b=0.09 [0.04,0.14] p<0.01). Significant sex interactions (p<0.05) emerged for midlife cardiovascular health (age 53) and NAWM at 70: marginal effect plots demonstrated, in women only, NAWM was associated with higher midlife FHS-CVS (lower FA and NDI), midlife systolic (lower FA, NDI, and higher MD), and diastolic (lower FA and NDI) blood pressure, and greater blood pressure change between 43 and 53 years (lower FA and NDI), independently of WMHV. In summary, poorer NAWM microstructural integrity in ∼70-year-olds was associated with measures of cerebral small vessel disease, amyloid (in males) and later-life cardiovascular health, demonstrating how NAWM can provide additional information to overt white matter disease. Our findings further show that greater midlife cardiovascular risk and higher blood pressure were associated with poorer NAWM microstructural integrity in females only, suggesting that women’s brains may be more susceptible to the effects of midlife blood pressure and cardiovascular health

Cholinergic Modulation of Narcoleptic Attacks in Double Orexin Receptor Knockout Mice

To investigate how cholinergic systems regulate aspects of the sleep disorder narcolepsy, we video-monitored mice lacking both orexin (hypocretin) receptors (double knockout; DKO mice) while pharmacologically altering cholinergic transmission. Spontaneous behavioral arrests in DKO mice were highly similar to those reported in orexin-deficient mice and were never observed in wild-type (WT) mice. A survival analysis revealed that arrest lifetimes were exponentially distributed indicating that random, Markovian processes determine arrest lifetime. Low doses (0.01, 0.03 mg/kg, IP), but not a high dose (0.08 mg/kg, IP) of the cholinesterase inhibitor physostigmine increased the number of arrests but did not alter arrest lifetimes. The muscarinic antagonist atropine (0.5 mg/kg, IP) decreased the number of arrests, also without altering arrest lifetimes. To determine if muscarinic transmission in pontine areas linked to REM sleep control also influences behavioral arrests, we microinjected neostigmine (50 nl, 62.5 µM) or neostigmine + atropine (62.5 µM and 111 µM respectively) into the nucleus pontis oralis and caudalis. Neostigmine increased the number of arrests in DKO mice without altering arrest lifetimes but did not provoke arrests in WT mice. Co-injection of atropine abolished this effect. Collectively, our findings establish that behavioral arrests in DKO mice are similar to those in orexin deficient mice and that arrests have exponentially distributed lifetimes. We also show, for the first time in a rodent narcolepsy model, that cholinergic systems can regulate arrest dynamics. Since perturbations of muscarinic transmission altered arrest frequency but not lifetime, our findings suggest cholinergic systems influence arrest initiation without influencing circuits that determine arrest duration
