Testing times: detecting HIV in resource-limited settings
Integrating HIV testing programmes into primary medical care can help achieve early diagnosis of HIV infection, even in relatively poor areas, research published in the online open access journal AIDS Research and Therapy has shown.
Researchers from Harvard Medical School and the non-governmental organisation Partners In Health (PIH, www.pih.org), both based in Boston, USA set out to see if HIV diagnosis was delayed because doctors missed opportunities to test people who were at risk of HIV during clinic visits.
The team works with the Haitian Ministry of Health to improve patients' access to primary care in central Haiti. This includes "provider-initiated HIV testing" (offering patients HIV tests when they visit primary care clinics) and the provision of free HIV treatment if required. The researchers then looked back at records from a single primary care clinic to examine the 'missed opportunities' and delays in diagnosing patients with HIV.
The researchers found few missed opportunities for diagnosis in the clinic - 85% of the first 112 patients found to have HIV were diagnosed on their first visit to the doctor. Patients with HIV who were not diagnosed on their first visit had to wait a median of just 62 days until diagnosis.
In the developing world, much HIV testing is done through maternity clinics or special HIV clinics that perform voluntary counselling and testing (i.e. on request of the individuals themselves) but that often do not provide other medical services or comprehensive HIV treatment. The authors suggest that provider-initiated testing at primary care clinics can be an effective way to identify patients with HIV infection.
They write: "HIV prevention and treatment programs will not achieve success without addressing the urgent need for individuals to be aware of their HIV status in a timely manner and provider-initiated testing can be a successful strategy to address this concern."
About AIDS Research and Therapy
AIDS Research and Therapy is an open access, online journal that publishes peer-reviewed research articles from scientists working to prevent the spread of AIDS. AIDS Research and Therapy aims to publish basic science as well as clinically important research articles that impact on abating the spread of AIDS. This multidisciplinary journal aims to keep scientists and clinicians abreast of the latest research on HIV-1. The ultimate goal of the journal's focus is to lead bench research to bedside practice to combat AIDS. AIDS is spreading at alarming rates in several African and Asian countries. Thus, any development that occurs in combating AIDS should be disseminated as rapidly as possible through the world. Although there are several AIDS-related journals in print, none of them are openly accessible to the world through the Internet. AIDS Research and Therapy will provide an open access journal specifically devoted to HIV-1 and AIDS research.
About BioMed Central
BioMed Central (http://www.biomedcentral.com) is a UK-based independent online publishing house committed to providing open access to peer-reviewed biological and medical research. This commitment is based on the view that immediate free access to research and the ability to freely archive and reuse published information is essential to the rapid and efficient communication of science.
BioMed Central currently publishes over 180 journals across biology and medicine. In addition to open-access original research, BioMed Central also publishes reviews, commentaries and other non-original-research content. Depending on the policies of the individual journal, this content may be open access or provided only to subscribers.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
