Actual Use of Multiple Health Monitors Among Older Adults With Diabetes: Pilot Study.

BACKGROUND: Previous studies have reported older adults' perceptions of using health monitors; however, no studies have examined the actual use of multiple health monitors for lifestyle changes over time among older adults with type 2 diabetes (T2D). OBJECTIVE: The primary aim of this study was to examine the actual use of multiple health monitors for lifestyle changes over 3 months among older adults with T2D. The secondary aim was to explore changes in caloric intake and physical activity (PA) over 3 months. METHODS: This was a single-group study lasting 3 months. The study sample included participants who were aged ≥65 years with a diagnosis of T2D. Participants were recruited through fliers posted at the Joslin Diabetes Center in Boston. Participants attended five 60-min, biweekly group sessions, which focused on self-monitoring, goal setting, self-regulation to achieve healthy eating and PA habits, and the development of problem-solving skills. Participants were provided with the Lose It! app to record daily food intake and devices such as a Fitbit Alta for monitoring PA, a Bluetooth-enabled blood glucose meter, and a Bluetooth-enabled digital scale. Descriptive statistics were used for analysis. RESULTS: Of the enrolled participants (N=9), the sample was white (8/9, 89%) and female (4/9, 44%), with a mean age of 76.4 years (SD 6.0; range 69-89 years), 15.7 years (SD 2.0) of education, 33.3 kg/m2 (SD 3.1) BMI, and 7.4% (SD 0.8) hemoglobin A1c. Over the 84 days of self-monitoring, the mean percentage of days using the Lose It!, Fitbit Alta, blood glucose meter, and scale were 82.7 (SD 17.6), 85.2 (SD 19.7), 65.3 (SD 30.1), and 53.0 (SD 34.5), respectively. From baseline to completion of the study, the mean daily calorie intake was 1459 (SD 661) at week 1, 1245 (SD 554) at week 11, and 1333 (SD 546) at week 12, whereas the mean daily step counts were 5618 (SD 3654) at week 1, 5792 (SD 3814) at week 11, and 4552 (SD 3616) at week 12. The mean percentage of weight loss from baseline was 4.92% (SD 0.25). The dose of oral hypoglycemic agents or insulin was reduced in 55.6% (5/9) of the participants. CONCLUSIONS: The results from the pilot study are encouraging and suggest the need for a larger study to confirm the outcomes. In addition, a study design that includes a control group with educational sessions but without the integration of technology would offer additional insight to understand the value of mobile health in behavior changes and the health outcomes observed during this pilot study.

Child Sexual Abuse and Depression in Late Life for Men: A Population-Based, Longitudinal Analysis.

OBJECTIVE: Research investigating long-term effects of childhood sexual abuse (CSA) on mental health for men is vastly underdeveloped. This study strengthened the knowledge base by examining: (a) long-term trajectories of depressive symptoms for men with and without a history of CSA, and (b) moderating effects of social support over time. METHOD: We analyzed multiple waves of data from the Wisconsin Longitudinal Study. The sample (N = 2,451) consisted of men with histories of CSA and a stratified, randomly sampled comparison group. Growth curve modeling was employed for analyses. RESULTS: After controlling for demographic, parental, and health factors, men with CSA histories had greater depressive symptoms than those with no history of CSA. For both groups, depressive symptoms decreased over time; slope patterns did not differ. We found a significant moderating effect of social support on the relationship between CSA and depressive symptoms. DISCUSSION: This innovative, population-based, longitudinal study demonstrated that CSA can undermine mental health for men across the life span and into old age. Social support appears to mitigate these deleterious effects. In early, middle, and late adulthood, practitioners should assess for CSA and strengthen support resources for male survivors.

Atypical face processing in children with tuberous sclerosis complex.

There is a high incidence of autism in tuberous sclerosis complex. Given the evidence of impaired face processing in autism, the authors sought to investigate electrophysiological markers of face processing in children with tuberous sclerosis complex. The authors studied 19 children with tuberous sclerosis complex under age 4, and 20 age-matched controls, using a familiar-unfamiliar faces paradigm. Of the children, 6 with tuberous sclerosis complex (32%) had autism. Children with tuberous sclerosis complex showed a longer N290 latency than controls (276 ms vs 259 ms, P = .05) and also failed to show the expected hemispheric differences in face processing. The longest N290 latency was seen in (1) children with autism and tuberous sclerosis complex and (2) children with temporal lobe tubers. This study is the first to quantify atypical face processing in children with tuberous sclerosis complex. This functional impairment may provide insight into a mechanism underlying a pathway to autism in tuberous sclerosis complex.

Electrical impedance myography in spinal muscular atrophy: a longitudinal study.

INTRODUCTION: New approaches for assessing disease progression in spinal muscular atrophy (SMA) are needed. In this study, we evaluate whether electrical impedance myography (EIM) can detect disease progression in SMA compared with a group of healthy children of similar age. METHODS: Twenty-eight children with SMA and 20 normal children underwent repeated EIM testing in four muscles at regular intervals for up to 3 years. An average rate of change of EIM was calculated for each subject and normalized to subcutaneous fat thickness and muscle girth. RESULTS: Multiple EIM parameters showed a change in normal subjects over a mean of 16.7 months; however, no change was found in SMA patients over this period. CONCLUSIONS: EIM could detect non-mass-dependent muscle maturation in healthy children. In contrast, the muscle in children with SMA, as measured by EIM, was virtually static, showing no evidence of growth or active deterioration.

Immune response to influenza vaccine in children with inflammatory bowel disease.

OBJECTIVES: Patients with inflammatory bowel disease (IBD) frequently receive immunosuppressive therapy. The immune response in these patients to vaccines has not been well studied. We conducted a prospective, open label study to evaluate the serologic response to influenza vaccine in children with IBD. METHODS: Serum was obtained from 146 children and young adults with IBD (96 Crohn's disease, 47 ulcerative colitis, and 3 indeterminate colitis) for baseline influenza titer, immediately followed by immunization with trivalent (A/Solomon Islands/3/2006 (H1N1), A/Wisconsin/67/2005 (H3N2), and B/Malaysia/2506/2004 (B)) inactivated influenza vaccine. Patients returned for repeat titers 3-9 weeks later. Seroprotection against each influenza strain was defined as hemagglutination inhibition titer > or = 40. Patients were categorized as nonimmunosuppressed (NIS; aminosalicylates only, antibiotics only, or no therapy) or immunosuppressed (IS; any immunosuppressive agent). IS patients were further subcategorized as: (i) tacrolimus, (ii) tumor necrosis factor-alpha (TNF-alpha) inhibitor, (3) immunomodulator, and (4) corticosteroids only. RESULTS: More patients were seroprotected against strains A/H1N1 and A/H3N2 than B strain (P<0.02), regardless of immunosuppression status. The proportion of seroprotected patients and geometric mean titers at post-vaccination were similar between NIS and IS groups for all three strains. Subanalysis of patients not seroprotected at baseline showed that those receiving anti-TNF therapy were less likely to be seroprotected against strain B (14%) compared to patients in the NIS group (39%, P=0.025). There were no serious vaccine-associated adverse events. CONCLUSIONS: Influenza vaccination produces a high prevalence of seroprotection in IBD patients, particularly against A strains. The vaccine is well tolerated. Routine influenza vaccination in IBD patients is recommended, irrespective of whether patients receive immunosuppressive medications.
