Risk Factors Associated with Missed Medical Appointments Among HIV-positive Young Men Who Have Sex with Men

Young men who have sex with men (YMSM) are overrepresented in the HIV epidemic in America. Retaining HIV positive YMSM in HIV care is very critical to reduce the overall burden of the HIV epidemic in America. Our study focused on identifying significant risk factors that affects retention in care for YMSM. Missing two or more medical appointments was how we measured retention in care. Using data gathered from ATN 086-106 study. This ATN cross-sectional study provided HIV positive males and females between the ages of 12 and 24 with an extensive questionnaire. The goal of this study was to analyze what risk factors are significantly associated with YMSM missing more than two or more appointments in the past 12 months. Our study found that African American and multi-racial young men were more likely to miss more than 2 appointments compared to whites. Methamphetamine, daily marijuana use, and declining mental health status caused individuals to miss multiple appointments

The state of the Martian climate

60°N was +2.0°C, relative to the 1981–2010 average value (Fig. 5.1). This marks a new high for the record. The average annual surface air temperature (SAT) anomaly for 2016 for land stations north of starting in 1900, and is a significant increase over the previous highest value of +1.2°C, which was observed in 2007, 2011, and 2015. Average global annual temperatures also showed record values in 2015 and 2016. Currently, the Arctic is warming at more than twice the rate of lower latitudes

Determination of cyclodextrin formation constants using dynamic coupled-column liquid chromatography

Dynamic coupled-column liquid chromatography is used to determine both aqueous solubilities and cyclodextrin inclusion complex formation constants for a series of polynuclear aromatic hydrocarbons (PAHs). This method Is based on the increase In solubility afforded by cyclodextrlns upon complexation. Formation constant (Kf) values are determined by using α-, β-, and γ-cyclodextrlns at various temperatures. The relative precision of the calculated Kf values is best for cyclodextrin/PAH complexes with large formation constants. The calculated solubilities are comparable to literature values, and in most cases, formation constant data are reproducible within 10%. The resulting Kf values confirm that the formation of Inclusion complexes is based on the relative sizes of host and guest molecules. © 1989, American Chemical Society. All rights reserved
