New model finds HIV acute phase infectivity may be lower than previously estimated

Anonym 0 15831 Article rating: 5.0
Previous calculations may have overestimated the importance of HIV transmission from recently infected individuals ("acute phase infectivity") in driving HIV epidemics, according to an article published by Steve Bellan of The University of Texas at Austin, and colleagues in this week's PLOS Medicine.
The lower estimates of acute phase infectivity suggest that recently infected individuals--who have not had the chance to start antiretroviral treatment--although still more infectious on average than those in the chronic stage of infection, are not as likely to infect others as was previously thought. Transmission from individuals in the acute phase of HIV infection could therefore pose less of a threat to effectiveness of Treatment as Prevention programs, while programs aimed at early identification of HIV infection could have less of a population-level impact, than previously thought.
The authors used two approaches to estimate acute phase infectivity. The first approach used viral load trajectories and the known relationship between viral load and infectivity to estimate that additional risk of transmission during the acute phase was equivalent to 5.6 extra months of chronic-phase infectivity (5.6 excess hazard months or EHMacute). The second approach used a mathematical model to simulate HIV infection and transmission among couples in the principal prior study that directly measured acute phase infectivity, a cohort study from Rakai, Uganda. This simulation estimated EHMacute to be 8.4. Both approaches yielded EHMacute estimates well below the two most cited previous estimates of acute phase infectivity (EHMacute 31 and 141). Bellan and colleagues determined that the higher estimates in previous studies were mainly the result of unaccounted-for heterogeneity in risk among study couples, and bias due to the exclusion of serodiscordant couples who were lost to follow-up. The authors caution that, even in their updated estimates, the small number of couples in this study result in wide confidence intervals.

CMU-Q Hosts Lecture on Arabic Language Learning

CARNEGIE Mellon University in Qatar (CMU-Q) recently hosted an 'Enhancing Teaching Arabic in Qatar' workshop for 25 primary, private and independent schoolteachers in an attempt to complement their language learning pedagogy.

Led by Zeinab Ibrahim, PhD, professor of Arabic Studies at CMU-Q and a renowned sociolinguist, 'Enhancing Teaching Arabic in Qatar' introduced the teachers to the linguistic theories behind the Arabiyyatti project, which is supported by the Qatar National Research Fund's National Priorities Research Program (NPRP).
Ibrahim said Arabiyyatti aims to introduce teachers to recent best practices in teaching Modern Standard Arabic (MSA) to schoolchildren. While Arab children are able to speak their local dialect, they are often unable to communicate using Modern Standard Arabic, otherwise known as fus'ha. 
"There are common problems with teaching Arabic across the entire region, and Arabiyyatti is the result of research indicating the need to support educators by introducing them to updated teaching methods as well as recent linguistic theories that deal with language acquisition and learning. I hope the participating instructors gained value from the workshop, and that it will inspire them to use Arabiyyatti in their classrooms not only for the benefit of their

HAMAD Medical Corporation (HMC) hosted the first Qatar International Pain Conference at the Qatar National Convention Center recently. It brought together 500 participants from Qatar and the abroad.
The aim of the event, organised by HMC's department of anaesthesiology, Intensive Care Unit and Perioperative Medicine in collaboration with Academic Health System (AHS) and support of Qatar National Research Fund (QNRF), was to share the latest knowledge about modern-day pain management. 
The event was attended by pain specialists, general physicians, medical students and delegates from academic, government and private institutions.

Islamic Medical and Scientific Ethics (IMSE) Collection

Anonym 0 16912 Article rating: No rating
Many of the items we bring you each week deal with our in house projects. Whether it is a new collection we are developing, a weekly program that has become a favorite or just an exploration of a great service we provide. These are all vital to what makes the Bioethics Research Library such a vibrant part of the bioethics community, but we would be remiss if we did not also occasionally highlight our larger, collaborative projects.
This week we are going to learn a little bit about our Islamic Medical and Scientific Ethics (IMSE) collection and show what can be accomplished when two libraries, thousands of miles apart, come together to create a truly unique resource.

Webinar set to focus on QF-funded research into infectious diseases

As scientists around the world grapple with the coronavirus pandemic, research funded by the Qatar Foundation (QF) to address infectious diseases will be on the spotlight this week.
 The latest edition of the Research Outcome Seminar series – an initiative of Qatar National Research Fund (QNRF) that highlights the impact of the projects it supports – will show how researchers in Qatar and beyond are developing new ways to reduce the spread of communicable diseases, and directly address the health risks they create.
