LOS ALAMOS, New Mexico -- The idea that one can create a field of science out of thin air, just because of societal and policy need, is a bold concept. But for the emerging field of sustainability science, sorting among theoretical and applied scientific disciplines, making sense of potentially divergent theory, practice and policy, the gamble has paid off.
Repeatedly taking slightly too much paracetamol over time can cause a dangerous overdose that is difficult to spot, but puts the person at danger of dying. Patients may not come to hospital reporting the overdose, but because they feel unwell. This clinical situation needs to be recognized and treated rapidly because these patients are at even greater danger than people who take single overdoses.
PROVIDENCE, R.I. -- Wrinkles and folds are ubiquitous. They occur in furrowed brows, planetary topology, the surface of the human brain, even the bottom of a gecko's foot. In many cases, they are nature's ingenious way of packing more surface area into a limited space. Scientists, mimicking nature, have long sought to manipulate surfaces to create wrinkles and folds to make smaller, more flexible electronic devices, fluid-carrying nanochannels or even printable cell phones and computers.
For persons with cardiovascular disease or diabetes, urinary sodium excretion (a surrogate for salt intake) at higher levels or at lower levels compared to mid-range values was associated with an increased risk of cardiovascular events (for higher levels) or cardiovascular death and hospitalization for congestive heart failure (for lower levels), according to a study in the November 23/30 issue of JAMA. Also, higher estimated urinary potassium excretion was associated with a reduced risk of stroke.
"It feels like there's two of you inside – like there's another half of you, which is my anorexia, and then there's the real K, the real me, the logic part of me, and it's a constant battle between the two." - 36 year old study participant with anorexia nervosa.
The Olympic Games are big business and generate substantial amounts of revenue for the International Olympic Committee (IOC) through lucrative television contracts and corporate sponsorship. The Games are now also widely perceived as important promotional opportunities for cities seeking to reinforce their claims as 'world class' destinations for tourists and capital in the global economy.
Conventional wisdom would say that blocking a hole would prevent light from going through it, but Princeton University engineers have discovered the opposite to be true. A research team has found that placing a metal cap over a small hole in a metal film does not stop the light at all, but rather enhances its transmission.
The clinical trial was random, regulated, double-blinded and broad-based. The drug was tested on 457 patients, aged 16-45, who had been diagnosed with Type 1 diabetes a short time before joining the trial. The trial took place in around 40 medical centers in Europe, Israel and South Africa. The patients in the trial were randomly assigned to one of two groups: One received the trial drug (DiaPep277®) through a subcutaneous injection once every three months, for a period of two years, while the control group was given a placebo in the same way.
A magnetic force microscope (MFM) can determine the distribution of stray fields at a level of tens of nanometers near the surface of magnetic films, and therefore is an effective tool for observing the domain structures in magnetic grains of submicrometer size. At present, the coercivity of normal MFM cantilevers is about 0.3 kOe. Being affected by the magnetism of the measured material, the stability of these cantilevers is unsatisfactory. By applying a FePt layer, the coercivity can reach ~10 kOe.
Children who started eating fish before nine months of age are less likely to suffer from pre-school wheeze, but face a higher risk if they were treated with broad spectrum antibiotics in the first week of life or their mother took paracetamol during pregnancy. Those are the key findings from a large-scale Swedish study published in the December issue of Acta Paediatrica.
Researchers analysed responses from 4,171 randomly selected families, who answered questions when their child was six months, 12 months and four-and-a-half years of age.
A recent trial shows cognitive-behavioral therapy (CBT) reduces functional disability and depressive symptoms in adolescents with juvenile fibromyalgia. The psychological intervention was found to be safe and effective, and proved to be superior to disease management education. Full findings from this multi-site clinical trial are published in Arthritis & Rheumatism, a peer-reviewed journal of the American College of Rheumatology (ACR).
Although police officers are at a high risk of experiencing traumatic events (TE) in their work, they are no more likely than the general population to suffer from post-traumatic stress disorder (PTSD). These are the findings from the second phase of an original and groundbreaking study published by the Institut de recherche Robert-Sauvé en santé et en sécurité du travail (IRSST) on the risk and protective factors of post-traumatic stress reactions in Quebec police officers.
CHICAGO – Body Mass Index (BMI) appears to be associated with 30-day mortality risk following surgical procedures, and patients with a BMI of less than 23.1 appear to be at highest risk of death, according to a report published Online First by Archives of Surgery, one of the JAMA/Archives journals.
CHICAGO – Among older Medicare beneficiaries who underwent surgical treatment for diverticulitis, black race was associated with increased risk of urgent/emergency surgery, high risk of in-hospital mortality and higher total hospital charges, according to a report in the November issue of Archives of Surgery, one of the JAMA/Archives journals.
CHICAGO – Among patients with moderate to severe psoriasis, treatment options that are most compatible with their personal and professional life appear to be most important, and treatment location appears more important than probability and magnitude of treatment outcome, according to a report in the November issue of Archives of Dermatology, one of the JAMA/Archives journals.
