Qualitative Study Guiding the Design of a Person-Centered Shared Medical Appointment Model to Optimize Diabetes Care Delivery.

PURPOSE: The purpose of the study was to explore the shared medical appointment model (SMA) with youth with type 2 diabetes (T2DM) and their caregivers to identify health education needs, access barriers, and recommendations for intervention design. METHODS: Patient and caregiver focus group interviews were conducted in English and Spanish to address these objectives: (1) identify barriers to participation in group sessions, (2) identify barriers to diabetes self-management, and (3) prioritize preference for SMA themes. Qualitative analysis identified strategies for patient recruitment and engagement and recommendations for curriculum design of a future SMA model for youth with T2DM. RESULTS: Both adolescents and caregivers supported the development of an SMA model. Adolescents expressed concerns of initial discomfort and nervousness, whereas young adults described stigma as the main barrier to joining a group. Patients emphasized the importance of prioritizing youth comfort and families' convenience. Early adolescents and young adults preferred autonomy in the choice to join a group, whereas mid adolescents and caregivers preferred that the caregivers make that decision. Participants recommended nine topics regarding barriers to diabetes care. The topics that received the most enthusiasm were nutrition, exercise, navigating peer interactions, and stress management. CONCLUSIONS: Youth with T2DM and their caregivers perceived many benefits of an SMA model and provided feedback to guide the development of a health education curriculum that could be integrated into an SMA clinic.

Altered protein phosphatase 2A methylation and Tau phosphorylation in the young and aged brain of methylenetetrahydrofolate reductase (MTHFR) deficient mice.

Common functional polymorphisms in the methylenetetrahydrofolate reductase (MTHFR) gene, a key enzyme in folate and homocysteine metabolism, influence risk for a variety of complex disorders, including developmental, vascular, and neurological diseases. MTHFR deficiency is associated with elevation of homocysteine levels and alterations in the methylation cycle. Here, using young and aged Mthfr knockout mouse models, we show that mild MTHFR deficiency can lead to brain-region specific impairment of the methylation of Ser/Thr protein phosphatase 2A (PP2A). Relative to wild-type controls, decreased expression levels of PP2A and leucine carboxyl methyltransferase (LCMT1) were primarily observed in the hippocampus and cerebellum, and to a lesser extent in the cortex of young null Mthfr (-/-) and aged heterozygous Mthfr (+/-) mice. A marked down regulation of LCMT1 correlated with the loss of PP2A/Bα holoenzymes. Dietary folate deficiency significantly decreased LCMT1, methylated PP2A and PP2A/Bα levels in all brain regions examined from aged Mthfr (+/+) mice, and further exacerbated the regional effects of MTHFR deficiency in aged Mthfr (+/-) mice. In turn, the down regulation of PP2A/Bα was associated with enhanced phosphorylation of Tau, a neuropathological hallmark of Alzheimer's disease (AD). Our findings identify hypomethylation of PP2A enzymes, which are major CNS phosphatases, as a novel mechanism by which MTHFR deficiency and Mthfr gene-diet interactions could lead to disruption of neuronal homeostasis, and increase the risk for a variety of neuropsychiatric disorders, including age-related diseases like sporadic AD.

What are the clinical criteria justifying spinal manipulative therapy for neck pain?- a systematic review of randomized controlled trials.

OBJECTIVE: Manipulation and mobilization are used to treat neck pain. However, little is known about the diagnostic criteria used to determine the need for manipulation in cases of neck pain. The primary aim of this study was to determine what diagnostic criteria are used to identify which neck pain sufferers should receive spinal manipulation or mobilization. DESIGN: We systematically reviewed randomized controlled trials (RCT) involving mobilization or manipulation for neck pain. A data extraction pro forma was developed and trialled before two independent assessors extracted data sets from each RCT. A descriptive analysis was undertaken. RESULTS: Thirty RCTs met the inclusion criteria. Acute and chronic "Mechanical" neck pain was the most common (43%) diagnosis at recruitment to the RCTs but some (10%) included patients with cervicogenic headache. Clinical criteria were used to determine the need for neck manipulation in over half (63%) of the RCTs. This usually involved exclusion of serious conditions, manual examination for tenderness on palpation, and/or altered vertebral motion in the neck or upper thoracic region which are known to lack validity. The remainder of the RCTs did not report a diagnostic strategy. All RCTs lacked detail descriptions of diagnostic criteria or interventions used. CONCLUSIONS: This systematic review highlights the absence of reliable and valid diagnostic protocols to determine the need for spinal manipulation in persons presenting with non-serious, idiopathic, or whiplash-associated (grade II) neck pain. Guidelines requiring the reporting of valid diagnostic criteria are needed to improve the quality of RCTs concerning manual therapy.

The relationship between foot motion and lumbopelvic-hip function: a review of the literature.

Excessive pronation has been implicated in the development of numerous overuse injuries of the lower limb and is suggested to cause more proximal biomechanical dysfunction. Functional foot orthoses (FFO) are frequently prescribed for lower limb injury associated with excessive foot pronation and have been demonstrated to have efficacy with specific conditions. However, the mechanism of action of FFO is largely unknown. Research investigating the kinematic and kinetic changes associated with FFO use is inconclusive. Furthermore there is a growing body of evidence suggesting that changes to muscle activity patterns in response to FFO may be responsible for their therapeutic effect. Additionally, current research suggests dysfunction of musculature of the lumbopelvic-hip complex is involved in lower extremity functional changes and is related to the development some pathologies traditionally attributed to excessive foot pronation. Evidence of temporal coupling between the hip and the foot and changes in hip muscle activity associated with FFO use further suggest a relationship between proximal and distal lower limb function. The aim of this review is to discuss the association between foot and lumbopelvic-hip complex dysfunction and injury, assess the evidence for functional changes to lower limb and lumbopelvic-hip function with FFO use and finally to discuss the potential for changes to hip musculature activation with FFO use to influence distal mechanics and produce a therapeutic benefit.

Axial elongation following prolonged near work in myopes and emmetropes.

BACKGROUND/AIMS: To investigate the influence of a period of sustained near work upon axial length in groups of emmetropes (EMM) and myopes. METHODS: Forty young adult subjects (20 myopes and 20 emmetropes) were recruited for the study. Myopes were further classified as early onset (EOM), late onset (LOM), stable (SM) or progressing (PM) subgroups. Axial length was measured with the IOLMaster instrument before, immediately after and then again 10 min after a continuous 30 min near task of 5 D accommodation demand. Measures of distance objective refraction were also collected. RESULTS: Significant changes in axial length were observed immediately following the near task. EOM axial length elongated on average by 0.027±0.021 mm, LOM by 0.014±0.020 mm, EMM by 0.010±0.015 mm, PM by 0.031±0.022 mm and SM by 0.014±0.018 mm. At the conclusion of the 10 min regression period, axial length measures were not significantly different from baseline values. CONCLUSION: Axial elongation was observed following a prolonged near task. Both EOM and PM groups showed increases in axial length that were significantly greater than emmetropes.
