Experience of Being an Insider and an Outsider during a Qualitative Study with Men Who Have Experienced Significant Weight Loss

The major question being answered in the study is, “What is the experience of being an insider/outsider in a study regarding men and significant weight loss?” The purpose of the paper is to explore the experience of being both an insider and an outsider, and specifically to discuss how researcher status and self-disclosure emerged and impacted the research process. The methodology used in the research study is narrative inquiry, specifically self-narrative. In the study, membership role status was found to be difficult to define, inherently complex, and arbitrary at times. Additional research on the topic of membership role status is needed and the level of importance should be further explored for the specific population

A Need of Further Training for Marriage and Family Therapy Students’ on Food Addiction and Related Eating Disorders

The purpose of this study was to explore Marriage and Family Therapy students’ perspectives regarding food addiction and associated eating disorders, as a clinical treatment issue. In a standard addictions course housed in a Marriage and Family Therapy program approved by the Commission on Accreditation for Marriage and Family Therapy Education (COAMFTE), 20 students completed a qualitative survey where they reflected on the topic of food addiction, Binge Eating Disorder, and Bulimia Nervosa, within the context of individual, couple, and family relationships. In the study four major themes emerged, which included (1) Defining Food Addiction, (2) Perceptions of Eating Disorders, (3) Conceptualizing Systemic Treatment, and (4) Experiences in clinical training. Clinical implications, recommendations for MFT education, clinical practice, and future research are discussed. Findings suggest that while MFT students in the study were well versed in conceptualized systemic treatment, it was of a general treatment and understanding using MFT theory, and not in relation to or specifically concerning food addictions and their connection or distinction from Binge Eating Disorder and/or other eating disorders found in the Diagnostic and Statistical Manual, potentially impacting the level of skillfully and appropriately working with clients

Pastoral Leaders’ Perception of Obesity and Their Role Within Faith-Based Organizations

The purpose of this study was to explore the perspectives of pastoral leaders regarding obesity and health within faith-based organizations (FBOs). In this study, the authors focused on gaining additional insight regarding how pastoral leaders conceptualize and make sense of their roles in terms of health promotion within FBOs. Utilizing a qualitative research methodological approach, specifically Qualitative Description, authors administered a qualitative survey to 12 participants which yielded three emerging themes: (1) perceived scope, (2) understanding and use of resources, and (3) defining obesity through pastoral leaders’ perspectives. In the study, investigators discuss clinical implications and provide recommendations

Integrating pest population models with biophysical crop models to better represent the farming system

Farming systems frameworks such as the Agricultural Production Systems simulator (APSIM) represent fluxes through the soil, plant and atmosphere of the system well, but do not generally consider the biotic constraints that function within the system. We designed a method that allowed population models built in DYMEX to interact with APSIM. The simulator engine component of the DYMEX population-modelling platform was wrapped within an APSIM module allowing it to get and set variable values in other APSIM models running in the simulation. A rust model developed in DYMEX is used to demonstrate how the developing rust population reduces the crop's green leaf area. The success of the linking process is seen in the interaction of the two models and how changes in rust population on the crop's leaves feedback to the APSIM crop modifying the growth and development of the crop's leaf area. This linking of population models to simulate pest populations and biophysical models to simulate crop growth and development increases the complexity of the simulation, but provides a tool to investigate biotic constraints within farming systems and further moves APSIM towards being an agro-ecological framework

How Does Cryotherapy Effect Ankle Proprioception in Healthy Individuals?

Objectives: To investigate how a 15 minute Cryotherapy intervention effects proprioception by measuring Joint positional Sense (JPS) and static single legged balance. Design: Repeated measures design. Setting: Laboratory. Participants: Eighteen healthy university sports team students (11 males, 7 females) aged between 20-21 years. Main Outcome Measures: Participants were treated with 15 minutes Aircast Cryo-cuff. The subject’s skin temperature was measured before and immediately after 15 minutes Cryotherapy treatment. Ankle active joint positional sense (A-JPS) and passive joint positional sense (P-JPS) was measured at pre-test, immediately post-test and 5 minutes post-test. Static balance was measured by Centre of Pressure (CoP) mean path length, medial-lateral (ML) CoP mean Deviation and anterior-posterior (AP) CoP mean Deviation and mean time-to-boundary (TtB) Minima for AP and ML directions. Results: No significant differences found for the variables of JPS and static single balance testing after 15 minutes Cryotherapy treatment. However, mean differences for CoP mean path length and ML mean deviation were shown to improve following Cryotherapy treatment, results not previously found in the literature. Conclusion: Results suggest that 15 minute Cryo-cuff treatment doesn’t significantly affect proprioception. Although the effect of Cryotherapy on proprioception depends on cooling modality used, time frame applied and joint applied to

Results of the combined U.S. multicenter postapproval study of the Nit‐Occlud PDA device for percutaneous closure of patent ductus arteriosus

ObjectivesTo report the results of the Nit‐Occlud PDA prospective postapproval study (PAS) along with a comparison to the results of the pivotal and continued access trials.BackgroundThe Nit‐Occlud PDA (PFM Medical, Cologne, Germany), a nitinol coil patent ductus arteriosus (PDA) occluder, was approved by the Food and Drug Administration in 2013.MethodsThe PAS enrolled a total of 184 subjects greater than 6 months of age, weighing at least 5 kg, with PDAs less than 4 mm by angiography at 11 centers. Patients were followed prospectively at 2 months, 12 months, and 24 months postprocedure. These outcomes were compared to the 357 subjects enrolled in the pivotal and continued access protocols. Efficacy and safety data were reported.ResultsAmong 184 subjects enrolled for the PAS between 2014 and 2017, 180 (97.8%) had successful device implantation. After 12 months, 98.7% (150/152) had trivial or no residual shunt by echocardiography and two subjects had only small residual shunts. There were three device embolizations that were all retrieved by snare without clinical consequence. Together with the pivotal and continued access study, 97.4% (449/461) had complete echocardiographic closure at 12 months in 541 enrolled subjects. The composite success was 94.4%. There were no mortalities and no serious device‐related adverse events.ConclusionsThe Nit‐Occlud PDA is a safe and effective device for closure of a small to moderate sized PDA. There were no serious device‐related adverse events in a large cohort of three clinical trials.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/148398/1/ccd27995_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/148398/2/ccd27995.pd

Transplantation of canine olfactory ensheathing cells producing chondroitinase ABC promotes chondroitin sulphate proteoglycan digestion and axonal sprouting following spinal cord injury

Olfactory ensheathing cell (OEC) transplantation is a promising strategy for treating spinal cord injury (SCI), as has been demonstrated in experimental SCI models and naturally occurring SCI in dogs. However, the presence of chondroitin sulphate proteoglycans within the extracellular matrix of the glial scar can inhibit efficient axonal repair and limit the therapeutic potential of OECs. Here we have used lentiviral vectors to genetically modify canine OECs to continuously deliver mammalian chondroitinase ABC at the lesion site in order to degrade the inhibitory chondroitin sulphate proteoglycans in a rodent model of spinal cord injury. We demonstrate that these chondroitinase producing canine OECs survived at 4 weeks following transplantation into the spinal cord lesion and effectively digested chondroitin sulphate proteoglycans at the site of injury. There was evidence of sprouting within the corticospinal tract rostral to the lesion and an increase in the number of corticospinal axons caudal to the lesion, suggestive of axonal regeneration. Our results indicate that delivery of the chondroitinase enzyme can be achieved with the genetically modified OECs to increase axon growth following SCI. The combination of these two promising approaches is a potential strategy for promoting neural regeneration following SCI in veterinary practice and human patients

Dopaminergic Neuronal Loss, Reduced Neurite Complexity and Autophagic Abnormalities in Transgenic Mice Expressing G2019S Mutant LRRK2

Mutations in the leucine-rich repeat kinase 2 (LRRK2) gene cause late-onset, autosomal dominant familial Parkinson's disease (PD) and also contribute to idiopathic PD. LRRK2 mutations represent the most common cause of PD with clinical and neurochemical features that are largely indistinguishable from idiopathic disease. Currently, transgenic mice expressing wild-type or disease-causing mutants of LRRK2 have failed to produce overt neurodegeneration, although abnormalities in nigrostriatal dopaminergic neurotransmission have been observed. Here, we describe the development and characterization of transgenic mice expressing human LRRK2 bearing the familial PD mutations, R1441C and G2019S. Our study demonstrates that expression of G2019S mutant LRRK2 induces the degeneration of nigrostriatal pathway dopaminergic neurons in an age-dependent manner. In addition, we observe autophagic and mitochondrial abnormalities in the brains of aged G2019S LRRK2 mice and markedly reduced neurite complexity of cultured dopaminergic neurons. These new LRRK2 transgenic mice will provide important tools for understanding the mechanism(s) through which familial mutations precipitate neuronal degeneration and PD
