Cross-border conservation vital to protect birds in a climate-change world

Countries need to increase co-operation over conservation to protect birds and other wildlife in an era of climate change, according to a new continental-scale study.

Experts have established a new conservation index to help policy-makers to deal with the effects of climate change on birds in Africa, and it could assist governments across the world to protect wildlife areas and help species as climate change forces them to move to new areas.

Virtual laboratory predicts train vibrations

The construction of new rail lines, or the relocation of old ones underground, has increased society's interest over recent years in the vibrations produced by trains, especially among people who live or work near the tracks. Now a study headed by the Polytechnic University of Valencia (UPV) has made it possible to estimate the trajectory of vibrations from the point at which they are generated (wheel-rail contact) through to the ground.

Drug-eluting stents are preferred therapy for revascularization of chronic total occlusions

A systematic review of medical evidence has determined drug-eluting stents (DES) outperform bare metal stents (BMS) for revascularization of chronic total occlusions. Researchers found coated stents reduce restenosis and target revascularization, offering a safe approach with similar adverse events as BMS. Full findings are available in the February issue of Catheterization and Cardiovascular Interventions, a journal published by Wiley-Blackwell on behalf of The Society for Cardiovascular Angiography and Interventions.

Ancient teeth raise new questions about the origins of modern man

BINGHAMTON, NY – Eight small teeth found in a cave near Rosh Haain, central Israel, are raising big questions about the earliest existence of humans and where we may have originated, says Binghamton University anthropologist Rolf Quam. Part of a team of international researchers led by Dr. Israel Hershovitz of Tel Aviv University, Qaum and his colleagues have been examining the dental discovery and recently published their joint findings in the American Journal of Physical Anthropology.

Researchers identify the genotype of disorders causing cardiac sudden death syndrome

Researchers from the Hospital Virgen de las Nieves of the University of Granada have identified the most frequent mutations in the gene KCNH2 in patients with long QT syndrome.

Long Qt syndrome is a disorder of cardiac ionic channels that approximately affects one in every 2,500 people and may cause torsade de pointes episodes, which can trigger sudden death. This condition usually affects children and adolescents, and it is occasionally mistaken for convulsions, leading to a misdiagnosis of epilepsy.

Understanding patterns of seafloor biomass

Analysis of a comprehensive database has revealed strong links between biological productivity in the surface oceans and patterns of biomass and abundance at the seafloor, helping to explain large regional differences. The research was conducted by an international, multi-institutional research team including scientists from the National Oceanography Centre (NOC), and incorporated data from the Census of Marine Life (CoML).

Growing population of adult survivors of congenital heart disease requires specialized care

Philadelphia, PA, February 8, 2011 – For the one in 200 adults in Western societies born with congenital heart disease, adult survivors face a lifelong process of medical interactions. Treatments received during neonatal, childhood, and adolescent years affect future adult events. In the January/February issue of Progress in Cardiovascular Diseases ten articles explore our current understanding of adult congenital heart disease (ACHD) in survivors.

Researchers predict nearly 1.3 million cancer deaths in Europe in 2011

There will be nearly 1.3 million deaths from cancer in Europe in 2011 according to predictions from a study published in the cancer journal, Annals of Oncology today (Wednesday 9 February) [1].

The estimates, which have been reached after researchers used for the first time in Europe a new mathematical model for predicting cancer mortality, show a fall in overall cancer death rates for both men and women when compared to 2007. But they also highlight some areas of concern, particularly rising rates of lung cancer in women.

Childhood cancer research in danger

At a time when the effects of paediatric oncology research have meant that more and more children survive cancer, its funding is too low and dependent on short-term grants to be able to sustain this improvement in the long-term, says a report supported by the EU-funded 7th Framework Programme project Eurocancercoms and published on-line in ecancer today*.

Possible crimes against humanity by Burmese military in Chin State, Burma

The health impacts of human rights violations in Chin State, home to the Chin ethnic minority in Burma, are substantial and the indirect health outcomes of human rights violations probably dwarf the mortality from direct killings. These findings from a study by Richard Sollom from Physicians for Human Rights, Cambridge, Massachusetts, USA, and colleagues will be published in this week's PLoS Medicine and should encourage the international community to intensify its efforts to reduce human rights violations in Burma.

Heavy drinking in older teenagers has long- and short-term consequences

In a systematic review of current evidence published in this week's PLoS Medicine, the authors—Jim McCambridge from the London School of Hygiene & Tropical Medicine, London, UK, and colleagues—conclude that there is enough evidence to recommend that reducing drinking during late adolescence is likely to be important for preventing long-term adverse consequences of drinking, as well as protecting against more immediate harms.

Huge decline in HIV rates in Zimbabwe driven by fear of infection, says study

The big drop in the numbers of people infected with HIV in Zimbabwe is because of mass social change, driven by fear of infection, according to an international study reported today in the journal PLoS Medicine. The scientists unravelling the reasons behind this unexpected downturn now reveal what they hope are the most important lessons in the fight against the disease for the rest of Africa.

Gene protects lung from damage due to pneumonia, sepsis, trauma, transplants

Lung injury is a common cause of death among patients with pneumonia, sepsis or trauma and in those who have had lung transplants. The damage often occurs suddenly and can cause life-threatening breathing problems and rapid lung failure.

There are no effective treatments. Patients usually are put on ventilators to give their lungs a chance to heal, but there is little else doctors can do but wait and hope for the best.

Limited lymph node removal for certain breast cancer does not appear to result in poorer survival

CHICAGO – Among patients with early-stage breast cancer that had spread to a nearby lymph node and who received treatment that included lumpectomy and radiation therapy, women who just had the sentinel lymph node removed (the first lymph node to which cancer is likely to spread from the primary tumor) did not have worse survival than women who had more extensive axillary lymph node dissection (surgery to remove lymph nodes found in the armpit), according to a study in the February 9 issue of JAMA.

Elevated levels of cardiac biomarkers following CABG surgery associated with increased risk of death

CHICAGO – Patients who underwent coronary artery bypass graft surgery and had elevated levels of the cardiac enzymes creatine kinase or troponin in the 24 hours following surgery had an associated intermediate and long-term increased risk of death, according to a study in the February 9 issue of JAMA.
