Pill count has the greatest impact on adherence, survey reports
The total number of pills that need to be taken every day in HAART therapy has the greatest impact on adherence of 10 characteristics studied, according to a survey of HIV positive individuals, nearly two-thirds of whom had experienced at least three treatment regimens. The findings of the Perspectives on Adherence and Simplicity for HIV+ Patients on Antiretroviral Therapy (PASPORT) survey were presented here today at the 40th Annual Meeting of the Infectious Diseases Society of America (IDSA).
Of the 10 attributes evaluated in the survey, total pills per day had a mean attribute importance score of 14 percent, followed by dosing frequency (13 percent), adverse events (12 percent), diet restrictions (11 percent), pill size (10 percent); number of refills (9 percent) number of insurance co-pays (9 percent), number of prescriptions (8 percent) number of medication bottles (8 percent) and the requirement of bedtime dosing (6 percent).
In addition to assessing the relative impact on anticipated adherence of dosing characteristics, the survey participants also evaluated seven triple-HAART regimens frequently prescribed for patients with HIV, including three regimens comprising QD medications. The regimens were evaluated individually, and also in head-to-head paired comparisons in which each of the seven regimens was compared with every other regimen, for a total of 21 comparisons. Information about the specific attributes of each regimen, and pictures and symbols were used to indicate features such as food requirements, pill size, number of pills and adverse event profiles.
Neither the brand nor the generic names of the medications were mentioned and identifying markers were obscured. The data collected in the survey are not necessarily representative of all HIV+ individuals. The survey population included 299 HIV+ patients ranging in age from 17 to 72 (median 43), 76 percent of whom were males. African Americans comprised approximately 45 percent of participants, Caucasians 38 percent, Hispanics 15 percent and Asian and other ethnic groups made up the remainder. The survey was conducted in six U.S. cities with a high proportion of citizens infected with HIV (Seattle, San Francisco, Miami, New York City, Atlanta and Washington, D.C.).
All individuals who participated in the survey were treatment-experienced with the majority having been on HAART regimens for four years or more. Of 295 patients who responded to a question on their current level of adherence, 26 percent reported no doses missed in the past three months. Another 32 percent said they had missed 1 or 2 doses; 24 percent said 3 to 5, 8 percent said 6 to 8, and 10 percent said 9 or more.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
