Mobile Health Technology for Improving Symptom Management in Low Income Persons Living with HIV.

Persons living with HIV (PLWH) are living longer but experiencing more adverse symptoms associated with the disease and its treatment. This study aimed to examine the impact of a mHealth application (app) comprised of evidence-based self-care strategies on the symptom experience of PLWH. We conducted a 12-week feasibility study with 80 PLWH who were randomized (1:1) to a mHealth app, mobile Video Information Provider (mVIP), with self-care strategies for improving 13 commonly experienced symptoms in PLWH or to a control app. Intervention group participants showed a significantly greater improvement than the control group in 5 symptoms: anxiety (p = 0.001), depression (p = 0.001), neuropathy (p = 0.002), fever/chills/sweat (p = 0.037), and weight loss/wasting (p = 0.020). Participants in the intervention group showed greater improvement in adherence to their antiretroviral medications (p = 0.017) as compared to those in the control group. In this 12-week trial, mVIP was associated with improved symptom burden and increased medication adherence in PLWH.

Outcomes of The BODY Project: A Program to Halt Obesity and Its Medical Consequences in High School Students.

Adolescent obesity continues to be a major public health issue with a third of American adolescents being overweight or obese. Excess weight is associated with cardiovascular risk factors and pre-diabetes. High school students identified as carrying excess weight [body mass index (BMI) ≥25 kg/m(2), or BMI percentile ≥85 %] were invited to participate in The BODY Project, an intervention that included a medical evaluation and a personalized medical report of the results of that evaluation sent to the parent/guardian at home. The medical evaluation and report was repeated 12 months later. The reports also contained advice on how the individual student could modify their lifestyle to improve the specific medical parameters showing abnormalities. Outcomes were change in BMI, blood pressure, high-density lipoprotein (HDL), low-density lipoprotein (LDL), fasting glucose, and fasting insulin. Students participating in The BODY Project intervention demonstrated modest, yet significant, reductions in BMI (p < 0.001) 1 year later, and also had significant improvements in systolic blood pressure (p < 0.001) and cholesterol profile (HDL p = 0.002; LDL p < 0.001) at follow-up. The BODY Project, by means of a minimal educational program anchored on the principle of teachable moments around the students' increased perception of their own risk for disease from the medical abnormalities uncovered, demonstrates evidence of potential effectiveness in addressing adolescent obesity.

Cognitive functions among predominantly minority urban adolescents with metabolic syndrome.

The rise in the rate of adolescent obesity has led to a concurrent rise in the rate of metabolic syndrome (MetS) among young people. In addition to diabetes and cardiovascular disease, MetS has also been linked to cognitive dysfunction. The goal of this study was to assess whether cognitive differences exist between minority urban adolescents carrying excess weight who meet criteria for MetS as compared to their peers without MetS. Two hundred and ninety-six urban adolescents, predominantly Hispanic and carrying excess weight as defined by a BMI above 25 kg/m2, were screened for MetS and divided into MetS and no MetS groups. All participants completed the CNS Vital Signs (CNS-VS) computerized neurocognitive battery that assesses cognitive domains of Memory, Processing Speed, Reaction Time, Executive Function, Complex Attention, and Cognitive Flexibility. The MetS group (29.2%, n = 84) performed significantly lower on 2 of the 7 cognitive domains: Executive Function (EF) and Cognitive Flexibility. Additionally, waist circumference was determined to be a significant predictor of both these domains. These findings suggest EF is negatively impacted in adolescents with MetS, despite there being no statistical differences between MetS groups on most other measured cognitive domains. Due to the interrelated nature of obesity, waist circumference, and MetS, these findings have larger implications for the obesity epidemic as well.

An open resource for transdiagnostic research in pediatric mental health and learning disorders.

Technological and methodological innovations are equipping researchers with unprecedented capabilities for detecting and characterizing pathologic processes in the developing human brain. As a result, ambitions to achieve clinically useful tools to assist in the diagnosis and management of mental health and learning disorders are gaining momentum. To this end, it is critical to accrue large-scale multimodal datasets that capture a broad range of commonly encountered clinical psychopathology. The Child Mind Institute has launched the Healthy Brain Network (HBN), an ongoing initiative focused on creating and sharing a biobank of data from 10,000 New York area participants (ages 5-21). The HBN Biobank houses data about psychiatric, behavioral, cognitive, and lifestyle phenotypes, as well as multimodal brain imaging (resting and naturalistic viewing fMRI, diffusion MRI, morphometric MRI), electroencephalography, eye-tracking, voice and video recordings, genetics and actigraphy. Here, we present the rationale, design and implementation of HBN protocols. We describe the first data release (n=664) and the potential of the biobank to advance related areas (e.g., biophysical modeling, voice analysis).

Does Inflammation Mediate the Association Between Obesity and Insulin Resistance?

In adult obesity, low-grade systemic inflammation is considered an important step in the pathogenesis of insulin resistance (IR). The association between obesity and inflammation is less well established in adolescents. Here, we ascertain the importance of inflammation in IR among obese adolescents by utilizing either random forest (RF) classification or mediation analysis approaches. The inflammation balance score, composed of eight pro- and anti-inflammatory makers, as well as most of the individual inflammatory markers differed significantly between lean and overweight/obese. In contrast, adiponectin was the only individual marker selected as a predictor of IR by RF, and the balance score only revealed a medium-to-low importance score. Neither adiponectin nor the inflammation balance score was found to mediate the relationship between obesity and IR. These findings do not support the premise that low-grade systemic inflammation is a key for the expression of IR in the human. Prospective longitudinal studies should confirm these findings.
