Suicide risk factors mapped

2013-06-10
(Press-News.org) A landmark study of the Swedish population has given a clearer picture of important risk factors for suicide.

The study, a collaboration between Lund University in Sweden and Stanford University, showed that the rate of suicide among men is almost three times that of women. Being young, single and having a low level of education were stronger risk factors for suicide among men, while mental illness was a stronger risk factor among women. Unemployment was the strongest social risk factor among women, whereas being single was the strongest among men.

Because the study covered a range of different diseases in both in-patient and out-patient care as well as social factors, the researchers gained insight into which factors are particularly important to bear in mind when assessing the risk of suicide.

"Better strategies are needed for collaboration between different disciplines and wider society in order to reduce the risk of suicide for individuals who suffer from, for example, depression, anxiety, COPD, asthma and certain social risk factors", says principal investigator Professor Jan Sundquist.

Of those who committed suicide, 29.5% of women and 21.7% of men had visited a doctor in the two weeks prior to their suicide, and 57.1% of women and 44.9% of men had visited a doctor within the 13 weeks prior to their suicide.

"This shows that many had contact with the health service a relatively short time before committing suicide. The results have clinical significance for those working in both primary care and other out-patient and in-patient care, including psychiatry. Besides the health service, social support services may need to be involved in the work to reduce the number of suicides in society", concludes Jan Sundquist.

### Results:

Depression (32-fold risk for suicide), anxiety (15-fold risk), COPD (3.05-fold risk), asthma (2.25-fold risk), stroke (1.67-fold risk) and cancer (1.72-fold risk). Those who have poor social networks are also at higher risk of suicide (e.g. divorced 2.25-fold risk).

About the study:

The researchers used the Swedish population and health register and were therefore able to follow over seven million adults between 2001 and 2008. Of these, 8 721 committed suicide.

Catching individual molecules in a million with optical antennas inside nano-boxes

2013-06-10
A single cell in our body is composed of thousands of millions of different biomolecules that work together in an extremely well-coordinated way. Likewise, many biological and biochemical reactions occur only if molecules are present at very high concentrations. Understanding how all these molecules interact with each other is key to advancing our knowledge in molecular and cell biology. This knowledge is of central and fundamental importance in the quest for the detection of the earliest stages of many human diseases. As such, one of ultimate goals in Life Sciences and ...

Study reveals leakage of carbon from land to rivers, lakes, estuaries and coastal regions

2013-06-10
When carbon is emitted by human activities into the atmosphere it is generally thought that about half remains in the atmosphere and the remainder is stored in the oceans and on land. New research suggests that human activity could be increasing the movement of carbon from land to rivers, estuaries and the coastal zone indicating that large quantities of anthropogenic carbon may be hidden in regions not previously considered. The research, published in Nature Geoscience and led by researchers from the Université Libre de Bruxelles, the University of Exeter, Laboratoire ...

The secret life of knots

2013-06-10
Nanotechnologies require a detailed knowledge of the molecular state. For instance, it is useful to know when and how a generic polymer, a long chain of polymers (chain of beads), knots. The study of molecular entanglement is an important field of study as the presence of knots affects its physical properties, for instance the resistence to traction. Previous studies had mainly obtained "static" data on the knotting probability of such molecules. In other words, they focused on the likelihood that a polymer may knot. The novelty of the study carried out by Micheletti ...

Uni Basel researchers discover master regulator in cancer metastasis

2013-06-10
The predominant cause of death in cancer patients is metastasis, the formation of secondary tumors in other organs like the brain, liver, and lungs. Cancer cells detach from the original primary tumor and reach a single cell or group of cells in another organ. The cells of the body normally remain in place through adhering to an extracellular substance. However, cancer cells learn how to release themselves from these bonds and invade surrounding tissues, blood, and the lymphatic system. The transformation of sedentary, specialized cells into wandering, invasive, and ...

Do antidepressants impair the ability to extinguish fear?

2013-06-10
An interesting new report of animal research published in Biological Psychiatry suggests that common antidepressant medications may impair a form of learning that is important clinically. Selective serotonin reuptake inhibitors, commonly called SSRIs, are a class of antidepressant widely used to treat depression, as well as a range of anxiety disorders, but the effects of these drugs on learning and memory are poorly understood. In a previous study, Nesha Burghardt, then a graduate student at New York University, and her colleagues demonstrated that long-term SSRI treatment ...

Treatment of mental illness lowers arrest rates, saves money

2013-06-10
Research from North Carolina State University, the Research Triangle Institute (RTI) and the University of South Florida shows that outpatient treatment of mental illness significantly reduces arrest rates for people with mental health problems and saves taxpayers money. "This study shows that providing mental health care is not only in the best interest of people with mental illness, but in the best interests of society," says Dr. Sarah Desmarais, an assistant professor of psychology at NC State and co-author of a paper describing the research. The researchers wanted ...

How Archaea might find their food

2013-06-10
The microorganism Methanosarcina acetivorans lives off everything it can metabolize into methane. How it finds its sources of energy, is not yet clear. Scientists at the Ruhr-Universität Bochum together with colleagues from Dresden, Frankfurt, Muelheim and the USA have identified a protein that might act as a "food sensor". They characterized the molecule in detail and found both similarities and differences to the system that is responsible for the search for food in bacteria. The team reports in the Journal of Biological Chemistry. MsmS has a different function to that ...

Split liver transplants for young children proven to be as safe as whole organ transplantation

2013-06-10
Boston, Mass.— A new study shows that when a liver from a deceased adult or adolescent donor is split into two separate portions for transplantation—with the smaller portion going to a young child and the larger to an adult—the smaller portion used for the child will last just as long as if the child had received a whole organ from a donor close to his size. The data, collected and analyzed by a team led by Boston Children's Hospital researchers Heung Bae Kim, MD, and Ryan Cauley, MD, MPH, was published online in Liver Transplantation, a journal of the American Association ...

Research shows river dredging reduced fish numbers, diversity

2013-06-10
Comparing dredged and undredged sections of the Allegheny River, reduced populations of fish and less variety of aquatic life occurred in areas where gravel extraction took place, according to researchers in Penn State's College of Agricultural Sciences,. The researchers investigated navigation pools 7 and 8 near Kittanning and Templeton and published their results in the journal Freshwater Biology. "Understanding and untangling the complex effects of human activities on aquatic ecosystems present a challenge to ecologists and resource managers," said lead investigator ...
