Being more realistic about the public health impact of genomic medicine

Press release from PLoS Medicine

2010-10-13
(Press-News.org) Wayne Hall, Rebecca Mathews and Katherine Morley discuss the limitations of genomic risk prediction for population-level preventive health care. Whilst genome-wide association studies and genomic sequencing have the potential to reveal susceptibilities to disease, they sound a note of caution about widescale implementation of such tests. In particular they point out that before genomic information is used in public health screening, it must first be shown that it predicts disease risk better than phenotypic information. They go on to point out that before genomic information can be used population wide, there must be cost-effective interventions available for those who would be found to be at risk, that such an approach would be more cost-effective than population-level interventions and finally that genetic risk information motivates the desired behaviour change. Currently there are no examples of genetic screening for disease risk that satisfy these criteria.

Economic advantage to pediatric ondansetron administration in emergency departments

2010-10-13
In research published this week in PLoS Medicine, Stephen Freedman (University of Toronto) and colleagues performed a cost analysis of the emergency department administration of oral ondansetron to children with dehydration and vomiting secondary to gastroenteritis and found that this treatment could provide substantial economic, as well as clinical, benefit. The researchers analyzed the costs of the administration of oral ondansetron in both the US and Canada, if routinely given to children with gastroenteritis-induced vomiting and dehydration in the emergency department ...

Study of planarian hormones may aid in understanding parasitic flatworms

Study of planarian hormones may aid in understanding parasitic flatworms
2010-10-13
CHAMPAIGN, Ill. — A study of peptide hormones in the brain of a seemingly primitive flatworm reveals the surprising complexity of its nervous system and opens up a new approach for combating a major parasitic disease, researchers report. The study appears in the open-access journal PLoS Biology. The planarian flatworm, Schmidtea mediterranea, is perhaps best known for its prodigious powers of regeneration. Cut it in half (lengthwise or crosswise) and each fragment will regrow its missing parts, including its brain. The planarian is of interest to those studying reproduction ...

Implanting medication to treat opioid dependence appears beneficial in decreasing opioid usage

2010-10-13
Helping to address the issue of medication adherence, persons with opioid dependence who had the medication buprenorphine implanted had less opioid use over 16 weeks, according to a study in the October 13 issue of JAMA. Dependence on opioids, in the form of heroin or prescription pain medications, is a significant health concern. A treatment that has been increasing in usage is the medication buprenorphine, with numerous studies supporting the efficacy of sublingually (beneath the tongue) administered buprenorphine. However, poor treatment adherence, resulting in craving ...

Restrictive use of blood transfusions during cardiac surgery shows comparable outcomes

2010-10-13
Use of stricter guidelines for the use of red blood cell transfusions for patients undergoing cardiac surgery was associated similar rates of death and severe illness compared to patients who received more transfusions, according to a study in the October 13 issue of JAMA. Another study in this issue of JAMA examines the variation in the use of blood transfusions for patients undergoing cardiac surgery. Cardiac surgery is associated with a high rate of blood transfusion. The rationale for red blood cell (RBC) transfusion is based on the observation that anemia is an independent ...

Rates of blood transfusions for CABG surgery varies widely among US hospitals

2010-10-13
A study that includes data on more than 100,000 patients who underwent coronary artery bypass graft surgery finds that there is wide variability among hospitals in the U.S. on the use of blood transfusions, without a large difference in the rate of death, suggesting that many transfusions may be unnecessary, according to a study in the October 13 issue of JAMA. Another study in this issue of JAMA examines the effect of a restrictive transfusion strategy on outcomes after cardiac surgery. "Patients who undergo cardiac surgery receive a significant proportion of the 14 ...

Considerable proportion of patients with advanced cancer continue to undergo common cancer screening

2010-10-13
A sizeable proportion of patients with advanced cancer and a life expectancy of only a few years continue to undergo common cancer screening tests that are unlikely to provide meaningful benefit, according to a study in the October 13 issue of JAMA. Cancer screening programs, such as mammography, Papanicolaou test, prostate-specific antigen (PSA) and colonoscopy, evaluate asymptomatic patients for the detection of early forms of cancer and have contributed substantially to the decline in deaths from cancer. "Although the benefits of cancer screening are compelling for ...

Transfusion rates vary extremely in cardiac bypass surgery

2010-10-13
DURHAM, NC – Transfusion rates for blood products used in a common heart surgery range from no patients to nearly all patients, and vary by hospital, according to findings from a group of researchers from Duke University Medical Center. The study, which looked at data from 102,470 patients in 798 hospitals, examined the variation in transfusion rates for red blood cells (RBCs), plasma and platelets, but the team didn't reach conclusions about how well patients fared if they did or didn't get a transfusion. "We don't know whether the variability is potentially harming ...

IOF campaign puts spotlight on vastly under-diagnosed and under-treated spinal fractures

2010-10-13
At a press conference held in Brussels today, the International Osteoporosis Foundation (IOF), the Belgian Bone Club and the European Parliament Osteoporosis Interest Group called on health care professionals and health policy officials in Europe to take action to prevent spinal fractures. The call to action was made at the launch of a unique photographic essay, 'snap! the breaking spine', leading up to World Osteoporosis Day on October 20, 2010. Taking viewers across the globe to Brazil, Canada, India, Jordan and Switzerland, the photographic essay captures a typical ...

Peer-based outreach services for sex workers assist entry into detox and drug treatment

2010-10-13
A mobile outreach program staffed by current and former sex workers is associated with increased entry to detoxification and residential drug treatment among women in street-based sex work, according to an evaluation led by the BC Centre for Excellence in HIV/AIDS (BC-CfE) and the University of British Columbia (UBC). The study, recently published in the peer-reviewed medical journal Drug and Alcohol Dependence, examined the link between accessing Vancouver's Mobile Access Project, or "the MAP van," and uptake of addiction treatment services by women engaged in street-based ...

No quick fix for peripheral artery disease -- repeat hospitalizations

2010-10-13
Even after initial procedures to clear blockages in leg arteries, hospitalizations and associated costs in patients with peripheral artery disease increase as the condition progresses, according to research reported in Circulation: Cardiovascular Quality and Outcomes, an American Heart Association journal. "We are dealing with clinically and economically severe consequences of PAD, a disease which is truly preventable," said Elizabeth Mahoney, Sc.D., the study's lead author. "Our prior research estimated that vascular-related hospitalizations for PAD patients cost the ...
