The researchers say 93 per cent of new infections among women are acquired through sexual transmission and seven per cent through injection drug use. About 60 per cent of newly infected women are immigrants. The findings, the latest from the POWER (Project for an Ontario Women's Health Evidence-Based Report) study, suggest targeted prevention and intervention efforts are necessary to eliminate gaps and inequities in care for HIV patients.
"We have made real progress in preventing HIV infection and in treating people living with HIV, but we also identified several groups for whom important disparities persist, including older women, Aboriginal women, and women who have immigrated from countries where HIV is endemic," says Dr. Ahmed Bayoumi, lead author on the chapter and a physician at St. Michael's Hospital. "We also identified differences related to poverty, injection drug use, and geography. Our findings suggest that addressing such factors will be important for delivering universal, high-quality HIV care in Ontario."
The POWER Study — a joint study from St. Michael's Hospital and ICES — is the first in the province to provide a comprehensive overview of women's health in relation to income, education, ethnicity and geography. The findings are detailed in the report titled HIV Infection-the 11th chapter to be released as part of the study. Findings can be used by policymakers and health-care providers to improve access, quality and outcomes of care for Ontario women. The POWER Study was funded by Echo: Improving Women's Health in Ontario, an agency of the Ontario Ministry of Health and Long-Term Care.
"The POWER Study HIV Infection chapter reveals important gaps in prevention, access and clinical care," says Pat Campbell, CEO, Echo: Improving Women's Health in Ontario. "Findings support the need for strategies to promote HIV prevention and testing directed at hard to reach groups. We also need to improve access to care for women aged 55 and older to ensure earlier diagnosis and/or earlier entry to care. At the same time findings are helping to track improvements in care, evident in the high prenatal HIV screening rate (95%)."
The POWER study chapter, released today, examined the impact of HIV infection on Ontarians. Key findings include:
More than 4,700 women are living with HIV in Ontario, most of whom acquired HIV through sexual contact. This represents 18% of the estimated HIV infections in the province.
Women who emigrated from a country where HIV is endemic account for more than half of all new infections in 2008 among women.
Women reported lower rates of condom use than men.
Women who inject drugs report riskier injection behaviours than men.
One third of users of community based HIV services are women
Over 90% of HIV-positive pregnant women who knew their HIV status received antiretrovirals during pregnancy, which could prevent transmission to the newborn.
"High rates of prenatal HIV screening show that when we have an organized and targeted program we can achieve measurable improvements in care," says Dr. Arlene Bierman, a physician at St. Michael's Hospital and principal investigator of the study. "We need to develop programs that ensure that all women who are at risk are screened and when tests are positive that they receive HIV care in a timely manner. Routine monitoring of quality indicators will allow us to evaluate these programs," adds Dr. Bierman, also an ICES investigator.

At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.
Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...
Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
