#1
Ben D Kern, Kim C Graber
Physical education is critical to addressing childhood obesity, yet many school-based programs do not meet established quality standards and teachers are called upon to change. Little is known about how change is initiated and its associated internal and external factors. PURPOSE: The purpose of this study was to investigate physical education teacher change that was self-initiated and externally initiated and to examine dispositions toward the change process relative to initiation. METHOD: A random national sample of physical educators representing each SHAPE America - Society of Health and Physical Educators regional district participated in a survey measuring past programming changes, primary initiators of change, and teachers' dispositions toward change...

Compartmental models were used to investigate the pharmacokinetics of intravenous (i.v.), oral (p.o.), and topical (TOP) administration of dimethyl sulfoxide (DMSO). The plasma concentration-time curve following a 15-min i.v. infusion of DMSO was described by a two-compartment model. Median and range of alpha (t1/2α ) and beta (t1/2β ) half-lives were 0.029 (0.026-0.093) and 14.1 (6.6-16.4) hr, respectively. Plasma concentration-time curves of DMSO following p.o. and TOP administration were best described by one-compartment absorption and elimination models...

Approximately 31% of men in treatment for a substance use disorders (SUD) engage in compulsive sexual behavior (CSB). Shame, a well-documented consequence of CSB, increases the likelihood of relapse following treatment for SUDs. Despite the risk of relapse, prior research has not investigated factors that may attenuate the relation between CSB and shame. Dispositional mindfulness is one such factor known to mitigate shame. However, researchers have yet to examine dispositional mindfulness as a moderator of the relationship between CSB and shame among a sample of men in treatment for SUDs...

This pilot study tested the independent and interactive effects of sleep and meal times, under identical sleep duration and feeding conditions, on insulin sensitivity (Si) in overweight adults. Participants underwent a 4-phase randomized crossover inpatient study differing in sleep times: normal (Ns: 0000-0800 hours) or late (Ls: 0330-1130 hours); and in meal times: normal (Nm: 1, 5, 11, and 12.5 hours after awakening) or late (Lm: 4.5, 8.5, 14.5, and 16 hours after awakening). An insulin-modified frequently sampled intravenous glucose tolerance test, at scheduled breakfast time, and a meal tolerance test, at scheduled lunch time, were performed to assess Si after 3 days in each condition...

In view of their superior soft tissue contrast compared to computed tomography, magnetic resonance images are commonly involved in stereotactic radiosurgery/radiotherapy applications for target delineation purposes. It is known, however, that magnetic resonance images are geometrically distorted, thus deteriorating dose delivery accuracy. The present work focuses on the assessment of geometric distortion inherent in magnetic resonance images used in stereotactic radiosurgery/radiotherapy treatment planning and attempts to quantitively evaluate the consequent impact on dose delivery...

Mindfulness is thought to promote well-being by shaping the way people respond to challenging social-emotional situations. Current understanding of how this occurs at the neural level is based on studies of response to decontextualized emotion stimuli that may not adequately represent lived experiences. In this study, we tested relations between mothers' dispositional mindfulness and neural responses to their own infant in different emotion-eliciting contexts. Mothers (n = 25) engaged with their 3-month-old infants in videorecorded tasks designed to elicit negative (arm restraint) or positive (peekaboo) emotion...

Mycophenolic acid (MPA) is an approved immunosuppressive agent widely prescribed to prevent rejection after kidney transplantation. Wide between-subject variability (BSV) in MPA exposure exists which in part may be due to variability in enterohepatic recirculation (EHC). Several modeling strategies were developed to evaluate EHC as part of MPA pharmacokinetics, however mechanistic representation of EHC is limited. These models have not provided a satisfactory representation of the physiology of EHC in their modeling assumptions...

A tension arises between society's disposition to protect people at risk from environmental pollution, and an aversion towards the potential harmful side-effects associated with cleanup activities. Here we explore how setting different cleanup standards may influence some of the environmental, social, and economic side-effects of remediation, and how they can be quantified for incorporation into cleanup target setting; these include (1) secondary environmental impacts, assessed by life cycle assessment (LCA); (2) fatalities and injuries, assessed by actuarial risk analysis; and (3) the cost effectiveness of stringent cleanup standards, assessed by the incremental cost-effectiveness ratio (ICER)...

BACKGROUND: Inpatient rehabilitation facilities (IRFs) and skilled nursing facilities (SNFs) represent a significant portion of post-operative expenses of bundled payments for total knee arthroplasty (TKA). Although many surgeons no longer routinely send patients to IRFs or SNFs, some patients are unable to be discharged directly home. This study identified patient factors for discharge to post-acute care facilities with an institutional protocol of discharging TKA patients home. METHODS: A retrospective review of patients undergoing primary unilateral TKA at a single institution from 2012 to 2017 was performed...

BACKGROUND: Dysfunctional expectations are considered to be core features of mental disorders and, in particular, major depression. The aim of the present study was to integrate two important types of expectations into the cognitive model of depression: situation-specific dysfunctional expectations (SDE) and dispositional optimism (DO). It was hypothesized that the influence of both DO and intermediate beliefs (IB) on depressive symptoms would be mediated via SDE. METHODS: We examined 95 individuals (age M = 40...

In carnivorous fish, conversion of a glucose load to hepatic glycogen is widely used to assess their metabolic flexibility towards carbohydrate utilization, but the activities of direct and indirect pathways in this setting are unclear. We assessed the conversion of an intraperitoneal glucose load (2 g.kg-1) enriched with [U-13C6]glucose to hepatic glycogen in juvenile seabass and seabream. 13C-NMR analysis of glycogen was used to determine the contribution of the load to glycogen synthesis via direct and indirect pathways at 48-hr post-injection...

BACKGROUND: While transient ischemic attack and minor stroke (TIAMS) are common conditions evaluated in the emergency department (ED), there is controversy regarding the most effective and efficient strategies for managing them in the ED. Some patients are discharged after evaluation in the ED and cared for in the outpatient setting, while others remain in an observation unit without being admitted or discharged, and others experience prolonged and potentially costly inpatient admissions...

Bumetanide is a loop diuretic that is proposed to possess a beneficial effect on disorders of the central nervous system, including neonatal seizures. Therefore, prediction of unbound bumetanide concentrations in brain is relevant from a pharmacological prospective. A physiologically-based pharmacokinetic (PBPK) model was developed for the prediction of bumetanide disposition in plasma and brain in adult and pediatric populations. A compound file was built for bumetanide integrating physicochemical data and in vitro data...

BACKGROUND: It is known that women with ST-segment elevation myocardial infarction (STEMI) have higher mortality in comparison to men. While the reasons for this sex-based difference are not completely understood, biologic differences and disparities in care have been implicated. Whether these differences persist within an urban, regional STEMI system of care with defined protocols is unclear. Our objective was to explore sex-related effects in outcomes in a large regional system of care...

This paper, through a deep examination of clinical workplaces as learning spaces, uses a holistic interpretation of clinical education and offers a practice development crucible metaphor as a useful way to deepen how clinical education can be conceptualized. An in-depth conceptualization of clinical education is needed if educators are able to develop wise educational practice and optimize the time students spend in clinical learning settings. The research reported here was undertaken in the qualitative paradigm guided by philosophical hermeneutics...
