Experts urge new discipline combining benefits of neuroscience, psychology treatments

Experts urge new discipline combining benefits of neuroscience, psychology treatments

When a patient talks with a psychological therapist, what changes occur in the patient’s brain that relieve mental disorders? UCLA psychology professor Michelle Craske says the honest answer is that we don’t know. Continue reading

Self-assembling nanoparticle could improve MRI scanning for cancer diagnosis

Self-assembling nanoparticle could improve MRI scanning for cancer diagnosis

Scientists have designed a new self-assembling nanoparticle that targets tumours, to help doctors diagnose cancer earlier. The new nanoparticle, developed by researchers at Imperial College London, boosts the effectiveness of Magnetic Resonance Imaging (MRI) scanning by specifically seeking out receptors that are found in cancerous cells Continue reading

Self-assembling nanoparticle could improve MRI scanning for cancer diagnosis

Scientists have designed a new self-assembling nanoparticle that targets tumours, to help doctors diagnose cancer earlier. The new nanoparticle, developed by researchers at Imperial College London, boosts the effectiveness of Magnetic Resonance Imaging (MRI) scanning by specifically seeking out receptors that are found in cancerous cells. The nanoparticle is coated with a special protein, which looks for specific signals given off by tumours, and when it finds a tumour it begins to interact with the cancerous cells. Continue reading

New assay to spot fake malaria drugs could save thousands of lives

New assay to spot fake malaria drugs could save thousands of lives

Chemists and students in science and engineering at Oregon State University have created a new type of chemical test, or assay, that’s inexpensive, simple, and can tell whether or not one of the primary drugs being used to treat malaria is genuine — an enormous and deadly problem in the developing world. The World Health Organization has estimated that about 200,000 lives a year may be lost due to the use of counterfeit anti-malarial drugs Continue reading

Text message medicine: Texts from the ER can reduce binge drinking

Text message medicine: Texts from the ER can reduce binge drinking

Young adults who screened positive for a history of hazardous or binge drinking reduced their binge drinking by more than 50 percent after receiving mobile phone text messages following a visit to the emergency department, according to a study published online yesterday in Annals of Emergency Medicine. “Each day in the U.S., more than 50,000 adults ages 18 to 24 visit ERs and up to half have hazardous alcohol use patterns,” said Brian Suffoletto, MD, of the University of Pittsburgh School of Medicine in Pittsburgh, Pa.

Women under-represented in academic medicine

Women under-represented in academic medicine

Women are under-represented in academic medicine resulting in a waste of public investment due to loss of research talent. Writing in the July issue of the Journal of the Royal Society of Medicine , authors of an essay on women and academic medicine say that as a consequence of female under-representation, some areas of medicine are under-researched at a cost to patients and society. Discriminatory practices and unconscious bias, they say, continue to occur in academic medicine, despite a substantial fall in traditional discrepancies between men and women in medicine in recent years Continue reading

Non-invasive urine test could be used to predict premature birth, delivery of small babies

Non-invasive urine test could be used to predict premature birth, delivery of small babies

Testing for the presence of specific molecules present in the urine of pregnant women can give an indication in early pregnancy of whether a baby will be born premature or the fetus will suffer poor growth, according to research published in the open access journal BMC Medicine . Identifying these conditions early in pregnancy could potentially help reduce complications and manage any difficulties, although more work is needed before the findings can be translated to clinical settings Continue reading

Healthcare worker hand hygiene rates increase three-fold when auditors visible

Healthcare worker hand hygiene rates increase three-fold when auditors visible

Hand hygiene rates were found to be three times higher when auditors were visible to healthcare workers than when there were no auditors present, according to a study in a major Canadian acute care hospital. The study, titled, “Quantification of the Hawthorne effect in hand hygiene compliance monitoring using an electronic monitoring system: a retrospective cohort study,” published today on-line in the BMJ Quality & Safety Journal , by first author Dr. Continue reading

Of non-marijuana drug users in the ER, nearly all are problem drug users

Of non-marijuana drug users in the ER, nearly all are problem drug users

Of emergency patients who reported any drug other than marijuana as their primary drug of use, 90.7 percent met the criteria for problematic drug use. Among patients who reported cannabis (marijuana) as their primary drug, almost half (46.6 percent) met the criteria for having a drug problem, according to a study published online in Annals of Emergency Medicine. “Of patients who reported any drug use in the previous 30 days, nearly two-thirds were identified as problem drug users,” said lead study author Wendy Macias-Konstantopoulos, MD, MPH, or the Department of Emergency Medicine at Massachusetts General Hospital in Boston, Mass Continue reading
