THT's One-hour 'Fastest' Service Aims To Reduce Undiagnosed HIV In Cardiff
In a bid to reduce levels of undiagnosed HIV in Cardiff, HIV and sexual health charity Terrence Higgins Trust (THT) is encouraging people who may have been at risk to attend a local service offering one-hour HIV testing. One in four people who have HIV in the UK are undiagnosed, and there are now more people living with the condition than ever before.

Teens Need To Hear About 'More Than Abstinence,' Philadelphia Inquirer Editorial Says
Although it is "important for other young people to hear" Bristol Palin"s message "about how hard it is to be a teenage mother," her "lesson falls short by suggesting that any teen can successfully avoid premarital sex," a Philadelphia Inquirer editorial says. Palin, who gave birth in December 2008 after an unintended pregnancy and is the daughter of Alaska Gov. Sarah Palin (R), has "changed her tune" since she said in a February interview that teen abstinence is ""not realistic at all,"" the editorial states. It adds that Bristol Palin -- now an "abstinence ambassador" for the Candie"s Foundation -- recently said that abstinence is "realistic" and that it is the "harder choice, but it"s the safer choice."The editorial continues that Palin is correct that "[a]bstinence is the only foolproof way to avoid pregnancy" and sexually transmitted infections. However, "any viable lesson about avoiding teen pregnancy should include methods besides avoiding sex, including the use of condoms," the editorial says. Recent studies have shown that abstinence-only sex education programs have had "no measurable impact on delaying teens from having sex for the first time," according to the editorial, which adds that teen pregnancy rates rose 5% between 2005 and 2007 after years of declines. Additionally, three out of 10 U.S. girls will get pregnant by age 20, a figure that increases to more than 50% for Hispanics and blacks. The editorial concludes that teens "need frank talk about premarital sex that includes all of the viable options to avoid pregnancy" (Philadelphia Inquirer, 5/15).

During Pregnancy, Women With Endometriosis Need Special Care To Avoid Risk Of Premature Birth
The largest study to date of endometriosis in pregnant women has found that the condition is a major risk factor for premature birth, the 25th annual conference of the European Society of Human Reproduction and Embryology heard. Dr. Henrik Falconer, of the Department of Woman and Child Health, Karolinska Institute, Stockholm, Sweden, said that his team had found that women with endometriosis also had a higher risk of other pregnancy complications, as well as being more likely to give birth through Caesarean section. The research is published on-line in the journal Human Reproduction*.

Close Relationship Between Past Warming And Sea-Level Rise

In a paper in Nature Geoscience, a team from the National Oceanography Centre, Southampton (NOCS), along with colleagues from TÃøbingen (Germany) and Bristol presents a novel continuous reconstruction of sea level fluctuations over the last 520 thousand years. Comparison of this record with data on global climate and carbon dioxide (CO2) levels from Antarctic ice cores suggests that even stabilisation at today"s CO2 levels may commit us to sea-level rise over the next couple of millennia, to a level much higher than long-term projections from the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC). Little is known about the total amount of possible sea-level rise in equilibrium with a given amount of global warming. This is because the melting of ice sheets is slow, even when temperature rises rapidly. As a consequence, current predictions of sea-level rise for the next century consider only the amount of ice sheet melt that will occur until that time. The total amount of ice sheet melting that will occur over millennia, given the current climate trends, remains poorly understood. The new record reveals a systematic equilibrium relationship between global temperature and CO2 concentrations and sea-level changes over the last five glacial cycles. Projection of this relationship to today"s CO2 concentrations results in a sea-level at 25 (±5) metres above the present. This is in close agreement with independent sea-level data from the Middle Pliocene epoch, 3-3.5 million years ago, when atmospheric CO2 concentrations were similar to the present-day value. This suggests that the identified relationship accurately records the fundamental long-term equilibrium behaviour of the climate system over the last 3.5 Million years. Lead author Professor Eelco Rohling of the University of Southampton"s School of Ocean and Earth Science based at NOCS, said: "Let"s assume that our observed natural relationship between CO2 and temperature, and sea level, offers a reasonable "model" for a future with sustained global warming. Then our result gives a statistically sound expectation of a potential total long-term sea-level rise. Even if we would curb all CO2 emissions today, and stabilise at the modern level (387 parts per million by volume), then our natural relationship suggests that sea level would continue to rise to about 25 m above the present. That is, it would rise to a level similar to that measured for the Middle Pliocene." Project partners Professor Michal Kucera (University of TÃøbingen) and Dr Mark Siddall (University of Bristol), add: "We emphasise that such equilibration of sea level would take several thousands of years. But one still has to worry about the large difference between the inferred high equilibrium sea level and the level where sea level actually stands today. Recent geological history shows that times with similarly strong disequilibria commonly saw pulses of very rapid sea-level adjustment, at rates of 1-2 metres per century or higher." The new study"s projection of long-term sea-level change, based on the natural relationship of the last 0.5 to 3.5 million years, differs considerably from the IPCC"s model-based long-term projection of +7 m. The discrepancy cannot be easily explained, and new work is needed to ensure that the "gap is closed". The observed relationships from the recent geological past can form a test-bed or reality-check for models, to help them achieve improved future projections.
