Objective Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have demonstrated significant efficacy in improving glycemic control in type 2 diabetes mellitus, which often results in decreased insulin dose requirements. The purpose of this study was to examine the changes in basal and prandial insulin dose requirements from baseline to three months following initiation of a GLP-1 RA. Methodology A retrospective chart review was conducted of adult insulin-treated patients at the Chertow Diabetes Center, Huntington, WV, who were started on GLP-1 RAs for 24 months.

Background: Pesticide applications using a specific droplet size and carrier volume could maximize herbicide efficacy while mitigating particle drift in a precise and efficient manner. The objectives of this study were to investigate the influence of spray droplet size and carrier volume on dicamba and glufosinate efficacy, and to determine the plausibility of droplet-size based site-specific weed management strategies.

Results: Generally, across herbicides and carrier volumes, as droplet size increased, weed control decreased.

Purpose: The purpose of this study was to determine whether there is adherence to the October 2011 American Academy of Pediatrics (AAP) recommendations for HIV screening in a large urban adolescent program with availability of a publicly funded program providing free, confidential, sexually transmitted infection (STI) and HIV counseling and testing (then rapid or third generation HIV testing), nested in the same adolescent clinic.

Methods: We conducted a retrospective chart review of HIV screening trends among 13- to 24-year-old patients tested for HIV during periods of January 2010 to June 2011 (18 months pre-AAP recommendations period) and July 2011 to December 2012 (18-month period, which included 15 months after the AAP recommendations).

Results: During the period of January 2010 to June 2011, there were 22 tests/1,000 medical visits (N = 824 of 37,520 medical visits), and during the period of July 2011 to December 2012, there were 27 tests/1,000 medical visits (N = 1,068 of 38,763 medical visits) ( < 0.

Purpose Of Review: Advances in HIV treatment, including simplified and better tolerated antiretroviral drug regimens, have led to increasing numbers of HIV-positive children and adolescents surviving into adulthood. Effective pediatric and adolescent primary care provided by pediatricians working together with an HIV specialist can help to optimize their current and future health.

Recent Findings: New data are showing youth with HIV may be at increased risk for early cardiovascular disease and metabolic derangements as compared with their uninfected peers.

Background: Previous research has shown that youth who are homeless engage in high-risk behaviors. However, there has been little information published on nutritional and physical activity behaviors in this population, and studies comparing homeless youth in school with their non-homeless peers are scarce. This study compares weight-related risk behaviors of public high school students in Massachusetts based on homeless status.

Objective: : To develop and evaluate an educational strategy to increase motivation to quit smoking and improve attendance at antismoking classes in a residential substance abuse treatment program.

Methods: : The 241 patients admitted in 2004 who smoked reported the number of cigarettes smoked daily at the time of admission. Attendance at the antismoking classes was noted to determine if there was a relationship between attending the classes and a change in the number of cigarettes smoked at discharge.

Phosphotriesterase (PTE) from Pseudomonas diminuta is a binuclear metalloenzyme that catalyzes the hydrolysis of organophosphate nerve agents at rates approaching the diffusion-controlled limit. The proposed catalytic mechanism postulates the interaction of the substrate with the metal center and subsequent nucleophilic attack by the bridging hydroxide. X-band EPR spectroscopy was utilized to monitor the active site of Mn/Mn-substituted PTE upon addition of two inhibitors, diisopropyl methyl phosphonate and triethyl phosphate, and the product of hydrolysis, diethyl phosphate.

Phosphotriesterase (PTE) is a binuclear metalloenzyme that catalyzes the hydrolysis of organophosphates, including pesticides and chemical warfare agents, at rates approaching the diffusion controlled limit. The catalytic mechanism of this enzyme features a bridging solvent molecule that is proposed to initiate nucleophilic attack at the phosphorus center of the substrate. X-band EPR spectroscopy is utilized to investigate the active site of Mn/Mn-substituted PTE.

Objectives: To assess the impact of outreach, mental health, and case management services on retention in primary care of HIV+ and at-risk youth and young adult clients of the Boston HAPPENS program, a comprehensive adolescent HIV prevention and care network of agencies.

Methods: Providers at 8 urban sites used standard data forms at each visit to collect background and service receipt information on at-risk clients aged 12-24 years. Data were aggregated across all visits for each client to create summary variables for the number of times each client received each type of service.

Postexposure prophylaxis is an effective intervention to prevent transmission of the human immunodeficiency virus (HIV). Administration of antiretroviral medications within 72 hours of a percutaneous or mucous membrane exposure to HIV can prevent infection. The use of postexposure prophylaxis for occupational and perinatal HIV exposures is well established.

With the advent of new therapies for HIV, case identification through HIV counseling and testing (CTS) has become critically important. Young women, youth of color, and disenfranchised youth are at significant risk of acquiring HIV. This study describes clients who access CTS at a program of comprehensive care for high-risk youth (aged 12 to 24 years), and assessed, using logistic regression analyses, whether youth at highest risk utilized CTS.
