Use of Behavior Change Techniques and Quality of Commercially Available Inflammatory Bowel Disease Apps.

BACKGROUND: Inclusion of evidence-based behavior change techniques (e.g., self-monitoring) in mobile health apps has the potential to promote adherence to inflammatory bowel disease treatment. While inflammatory bowel disease management apps exist, the extent to which they incorporate behavior change techniques remains unknown. AIMS: The present study systematically evaluated the content and quality of free, commercially available inflammatory bowel disease management apps. METHODS: Apps were identified using a systematic search of the Apple App and Google Play stores. Apps were evaluated using Abraham and Michie's taxonomy of 26 behavior change techniques. A literature search was conducted to identify behavior change techniques specific and relevant for people with inflammatory bowel disease. App quality was assessed using the Mobile App Rating Scale with scores ranging from 1 (Inadequate) to 5 (Excellent). RESULTS: A total of 51 inflammatory bowel disease management apps were evaluated. Apps included 0-16 behavior change techniques (Mean = 4.55) and 0-10 inflammatory bowel disease management behavior change techniques (Mean = 3.43). App quality ranged from 2.03 to 4.62 (Mean = 3.39) out of 5.00. Two apps, My IBD Care: Crohn's & Colitis and MyGiHealth GI Symptom Tracker, included the highest number of overall and inflammatory bowel disease management behavior change techniques along with high-quality scores. Bezzy IBD was the only app with a high number of overall and inflammatory bowel disease management behavior change techniques with a primary focus on social support/change. CONCLUSION: Most inflammatory bowel disease management apps reviewed included evidence-based inflammatory bowel disease management behavior change techniques.

The effect of HIV field-based testing on the proportion of notified partners who test for HIV in New York City.

HIV partner services can effectively reach populations with high HIV prevalence. However, located and notified sex and needle-sharing partners of persons infected with HIV often fail to test. Field testing may increase the proportion of notified partners who test for HIV. In 2008, New York City's health department incorporated field testing into partner services. After the introduction of field testing, the proportion of notified partners who tested for HIV rose from 52% to 76% (P<.001). HIV prevalence fell slightly among notified partners who accepted testing (12% to 9%, P=.82), but we identified more than double the number of new positives (11 vs 25). All positive and 97% of negative results were received by the person tested.

Apathy correlates with cognitive function but not CD4 status in patients with human immunodeficiency virus.

Apathy is a prominent neuropsychiatric symptom associated with human immunodeficiency virus (HIV). The increased frequency of apathy in this population may reflect the direct involvement of the virus on the central nervous system (CNS), but the severity of apathy has not been shown to consistently relate to markers of disease activity or other neuropsychiatric complications of the virus. We examined the relationship between ratings of apathy and performance on measures of cognitive function and immune system status in a sample of HIV-infected patients. Apathy was significantly elevated among HIV-infected individuals compared to healthy comparison subjects. Apathy was significantly related to performance on measures of learning efficiency and a measure of cognitive flexibility. Ratings of apathy did not relate to CD4 cell count, but they were associated with disease duration. In addition, ratings of depression were independent of ratings of apathy. These findings suggest that apathy does not co-vary with a proxy measure of active disease status, but apathy does relate to several measures of cognitive dysfunction in patients with HIV. As such, the increased prevalence of apathy among HIV-infected adults may reflect HIV-associated neurologic dysfunction.

Lipid changes in patients initiating efavirenz- and indinavir-based antiretroviral regimens.

PURPOSE: To evaluate nonfasting lipid levels in a large cohort of patients on three HAART regimens: efavirenz + zidovudine + lamivudine (EFV+ZDV+3TC), efavirenz + indinavir (EFV+IDV), and indinavir + zidovudine + lamivudine (IDV+ZDV+3TC). METHOD: Nonfasting lipid levels were analyzed from a large randomized multicenter treatment trial for HIV-infected patients initiating HAART. Treatment evaluations were carried out at prescribed intervals, and data were recorded and analyzed. Assessment was limited to high-density lipoprotein (HDL) and total cholesterol. RESULTS: The results demonstrate an increase in the total cholesterol, ranging from 23 to 57 mg/dL, in the three combinations of HAART therapy. The increase was most significant in the EFV+IDV arm where the effects appear to be additive. HDL cholesterol also increased in all three arms, but the greatest increase was in the two groups containing EFV. In all three arms, the HDL cholesterol increased significantly in women while increases in men were seen only in the EFV-containing arms. Men taking either IDV-containing regimen had a greater increase in total cholesterol, and therefore the total/HDL cholesterol ratio rose significantly. CONCLUSION: EFV and IDV independently elevate lipid levels. Alterations in the lipid levels may lead to increased cardiovascular risk in men, possibly mitigated by elevations in HDL cholesterol. In addition, changes in HDL cholesterol were significantly different between men and women.
