Publication Assessment of Barriers to Improve Diabetes Management in Older Adults: A randomized controlled study(American Diabetes Association, 2013) Munshi, Medha; Segal, Alissa R.; Suhl, Emmy; Ryan, Courtney; Sternthal, Adrianne; Giusti, Judy; Lee, Yishan; Fitzgerald, Shane; Staum, Elizabeth; Bonsignor, Patricia; DesRochers, Laura; McCartney, Richard; Weinger, KatieOBJECTIVE To evaluate whether assessment of barriers to self-care and strategies to cope with these barriers in older adults with diabetes is superior to usual care with attention control. The American Diabetes Association guidelines recommend the assessment of age-specific barriers. However, the effect of such strategy on outcomes is unknown. RESEARCH DESIGN AND METHODS We randomized 100 subjects aged ≥69 years with poorly controlled diabetes (A1C >8%) in two groups. A geriatric diabetes team assessed barriers and developed strategies to help patients cope with barriers for an intervention group. The control group received equal amounts of attention time. The active intervention was performed for the first 6 months, followed by a “no-contact” period. Outcome measures included A1C, Tinetti test, 6-min walk test (6MWT), self-care frequency, and diabetes-related distress. RESULTS We assessed 100 patients (age 75 ± 5 years, duration 21 ± 13 years, 68% type 2 diabetes, 89% on insulin) over 12 months. After the active period, A1C decreased by −0.45% in the intervention group vs. −0.31% in the control group. At 12 months, A1C decreased further in the intervention group by −0.21% vs. 0% in control group (linear mixed-model, P < 0.03). The intervention group showed additional benefits in scores on measures of self-care (Self-Care Inventory-R), gait and balance (Tinetti), and endurance (6MWT) compared with the control group. Diabetes-related distress improved in both groups. CONCLUSIONS Only attention between clinic visits lowers diabetes-related distress in older adults. However, communication with an educator cognizant of patients’ barriers improves glycemic control and self-care frequency, maintains functionality, and lowers distress in this population.Publication Diabetes in Older Adults(American Diabetes Association, 2012) Kirkman, M. Sue; Briscoe, Vanessa Jones; Clark, Nathaniel; Florez, Hermes; Haas, Linda B.; Halter, Jeffrey B.; Huang, Elbert S.; Korytkowski, Mary T.; Munshi, Medha; Odegard, Peggy Soule; Pratley, Richard E.; Swift, Carrie S.Publication Enhancement of Vasoreactivity and Cognition by Intranasal Insulin in Type 2 Diabetes(American Diabetes Association, 2014) Novak, Vera; Milberg, William; Hao, Ying; Munshi, Medha; Novak, Peter; Galica, Andrew; Manor, Bradley; Roberson, Paula; Craft, Suzanne; Abduljalil, AmirOBJECTIVE To determine acute effects of intranasal insulin on regional cerebral perfusion and cognition in older adults with type 2 diabetes mellitus (DM). RESEARCH DESIGN AND METHODS This was a proof-of-concept, randomized, double-blind, placebo-controlled intervention evaluating the effects of a single 40-IU dose of insulin or saline on vasoreactivity and cognition in 15 DM and 14 control subjects. Measurements included regional perfusion, vasodilatation to hypercapnia with 3-Tesla MRI, and neuropsychological evaluation. RESULTS Intranasal insulin administration was well tolerated and did not affect systemic glucose levels. No serious adverse events were reported. Across all subjects, intranasal insulin improved visuospatial memory (P ≤ 0.05). In the DM group, an increase of perfusion after insulin administration was greater in the insular cortex compared with the control group (P = 0.0003). Cognitive performance after insulin administration was related to regional vasoreactivity. Improvements of visuospatial memory after insulin administration in the DM group (R2adjusted = 0.44, P = 0.0098) and in the verbal fluency test in the control group (R2adjusted = 0.64, P = 0.0087) were correlated with vasodilatation in the middle cerebral artery territory. CONCLUSIONS Intranasal insulin administration appears safe, does not affect systemic glucose control, and may provide acute improvements of cognitive function in patients with type 2 DM, potentially through vasoreactivity mechanisms. Intranasal insulin-induced changes in cognitive function may be related to vasodilatation in the anterior brain regions, such as insular cortex that regulates attention-related task performance. Larger studies are warranted to identify long-term effects and predictors of positive cognitive response to intranasal insulin therapy.Publication Management of Diabetes in Long-term Care and Skilled Nursing Facilities: A Position Statement of the American Diabetes Association(American Diabetes Association, 2016) Munshi, Medha; Florez, Hermes; Huang, Elbert S.; Kalyani, Rita R.; Mupanomunda, Maria; Pandya, Naushira; Swift, Carrie S.; Taveira, Tracey H.; Haas, Linda B.Diabetes is more common in older adults, has a high prevalence in long-term care (LTC) facilities, and is associated with significant disease burden and higher cost. The heterogeneity of this population with regard to comorbidities and overall health status is critical to establishing personalized goals and treatments for diabetes. The risk of hypoglycemia is the most important factor in determining glycemic goals due to the catastrophic consequences in this population. Simplified treatment regimens are preferred, and the sole use of sliding scale insulin (SSI) should be avoided. This position statement provides a classification system for older adults in LTC settings, describes how diabetes goals and management should be tailored based on comorbidities, delineates key issues to consider when using glucose-lowering agents in this population, and provides recommendations on how to replace SSI in LTC facilities. As these patients transition from one setting to another, or from one provider to another, their risk for adverse events increases. Strategies are presented to reduce these risks and ensure safe transitions. This article addresses diabetes management at end of life and in those receiving palliative and hospice care. The integration of diabetes management into LTC facilities is important and requires an interprofessional team approach. To facilitate this approach, acceptance by administrative personnel is needed, as are protocols and possibly system changes. It is important for clinicians to understand the characteristics, challenges, and barriers related to the older population living in LTC facilities as well as the proper functioning of the facilities themselves. Once these challenges are identified, individualized approaches can be designed to improve diabetes management while lowering the risk of hypoglycemia and ultimately improving quality of life.Publication White Matter Hyperintensities and Dynamics of Postural Control(Elsevier BV, 2009-07) Novak, Vera; Haertle, Mareile; Zhao, Peng; Hu, Kun; Munshi, Medha; Novak, Peter; Abduljalil, Amir; Alsop, DavidBackground White matter hyperintensities (WMHs) on MRI have been associated with age, cardiovascular risk factors and falls in the elderly. This study evaluated the relationship between WMHs and dynamics of postural control in older adults without history of falls. Methods We studied 76 community-living subjects without history of falls (age 64.5±7.3 years). Brain and WMH volume calculations and clinical rating were done on fluid-attenuation inversion recovery (FLAIR) and MP-RAGE MR images on 3 T. Balance was assessed from the center of pressure displacement using the force platform during 3 min of quiet standing using traditional and dynamic measures (using stabilogram-diffusion analysis). Gait speed was measured from 12-min walk. Results Age-adjusted periventricular and focal WMHs were associated with changes in certain dynamic balance measures, including reduced range of postural sway in anteroposterior direction (fronto-temporal WMHs, P=.045; parieto-occipital WMHs, P=.009) and more irregular long-term mediolateral fluctuations (P=.046). Normal walking speed was not affected by WMHs. Conclusions Periventricular and focal WMHs affect long-term dynamics of postural control, which requires engagement of feedback mechanisms, and may contribute to mobility decline in the elderly.
