(Press-News.org) Should doctors recommend homeopathy? Two experts debate the issue in The BMJ this week.
Peter Fisher, Director of Research at the Royal London Hospital for Integrated Medicine, says that of all the major forms of complementary medicine, homeopathy is the most misunderstood.
He questions the methods used to review the evidence for homeopathy. For example, in a recent report by the Australian National Health and Medical Research Council which stated that "there are no health conditions for which there is reliable evidence that homeopathy is effective."
"The fact that one homeopathic treatment for a condition is ineffective doesn't mean that another is also ineffective." The review also unaccountably omitted several key pieces of evidence, he argues.
Most overviews have had more favourable conclusions, he says, including a Health Technology Assessment commissioned by the Swiss federal government which concluded that homeopathy is "probably" effective for upper respiratory tract infections and allergies - and several meta-analyses of homeopathy as a whole and for specific conditions have been positive
He also points to several studies comparing treatment outcomes of conventional family doctors with those who integrate homeopathy in their practice, showing better outcomes at equivalent cost in a range of conditions with reduced use of hazardous drugs including antibiotics.
He concludes that "Doctors should put aside bias based on the alleged implausibility of homeopathy. When integrated with standard care homeopathy is safe, popular with patients, improves clinical outcomes without increasing costs, and reduces the use of potentially hazardous drugs, including antimicrobials. Health professionals trained in homeopathy do not oppose the use of conventional treatments, including immunisation."
But Edzard Ernst, Emeritus Professor at the University of Exeter, says most independent systematic reviews of randomised controlled trials "have failed to show that homeopathy is effective" and reviews with positive conclusions "usually have serious methodological flaws."
The assumptions underlying homeopathy "fly in the face of science" he says "and critics have long pointed out that unless our understanding of the laws of nature is incorrect, homeopathy's mode of action has no rational explanation."
He also argues that homeopathy can harm "if it replaces an effective therapy" and says he knows of "several deaths that have occurred in this unnecessary way."
Finally, he questions Europe's €1bn annual spend on such remedies, saying these funds "could and should be spent more usefully elsewhere."
In summary, he says, "the axioms of homeopathy are implausible, it's benefits do not outweigh its risks, and its costs and opportunity costs are considerable. Therefore, it seems unreasonable, even unethical, for healthcare professionals to recommend its use."

Standardised mortality ratios (SMRs) for hospitals do not provide an accurate picture of how many deaths could have been avoided, according to a new study by researchers at the London School of Hygiene & Tropical Medicine and Imperial College London published in the BMJ.
The authors say the widely used hospital-wide standardised mortality ratios, such as HSMR (Hospital Standardised Mortality Ratio) and SHMI (Summary Hospital level Mortality Indicator), should not be used to benchmark hospitals' quality of care.
Hospital-wide SMRs compare the number of deaths in a hospital ...
The first comprehensive genome analyses of 7 melon varieties was completed by a research team led by Josep Casacuberta, Jordi Garcia-Mas and Sebastian Ramos-Onsins, providing breeders new knowledge important for understanding phenotypic variability and helping increasing plant quality yields by selective breeding. The findings were published in the advanced online edition of Molecular Biology and Evolution.
The researchers sought to bridge the gap between expanding the genetic knowledge of melons and understanding important traits such as flavor, size and water use.

Disruptions in a key brain region can explain the varied outcomes after a traumatic brain injury (TBI) in children and adolescents, according to research published July 15 in The Journal of Neuroscience. Post-injury outcomes vary widely, and injury severity can only explain some of this variance. Combining data from brain imaging and recording, researchers at the University of Southern California and UCLA found that disruptions in the structure and function of a brain region called the corpus callosum could explain the variance in cognitive outcomes.
TBI is the leading ...
Why do some youngsters bounce back quickly from a traumatic brain injury, while others suffer devastating side effects for years?
New UCLA/USC research suggests that damage to the fatty sheaths around the brain's nerve fibers--not injury severity-- may explain the difference. Published in the July 15 edition of the Journal of Neuroscience, the finding identifies possible biomarkers that physicians could use to predict higher-risk patients who require closer monitoring.
The study is the first to combine imaging scans with recording of the brain's electrical activity ...
WASHINGTON, DC, July 14, 2015 -- When a sound wave hits an obstacle and is scattered, the signal may be lost or degraded. But what if you could guide the signal around that obstacle, as if the interfering barrier didn't even exist? Recently, researchers at Nanjing University in China created a material from polyethylene membranes that does exactly that.
Their final product, described this week in the Journal of Applied Physics, from AIP Publishing, was an acoustical "metamaterial" with an effective density near zero (DNZ). This work could help to endow a transmission ...
A quick biological test may be able to identify children who have literacy challenges or learning disabilities long before they learn to read, according to new research from Northwestern University.
The study, publishing in the Open Access journal PLOS Biology on July 14th, centers on the child's ability to decipher speech -- specifically consonants -- in a chaotic, noisy environment. Preliterate children whose brains inefficiently process speech against a background of noise are more likely than their peers to have trouble with reading and language development when ...
A yearlong study of more than 300 patients found that the investigational drug patiromer can reduce elevated blood-potassium levels--a common side effect of drugs essential in the treatment of chronic diabetic kidney disease.
The drug, given in this trial at one of four doses based on disease severity, returned blood potassium levels to normal when measured at four weeks and kept them under control for one year, the length of the trial. By quickly bringing potassium levels back to normal and keeping them there, patiromer can prevent life-threatening adverse events.

The new guidelines for determining whether patients should begin taking statins to prevent cardiovascular disease issued in 2013 by the American College of Cardiology (ACC) and the American Heart Association (AHA) are more accurate and more efficient than an earlier set of guidelines in assigning treatment to adults at increased risk for cardiovascular events - including heart attacks and strokes - and identifying those whose low risk rules out the need to take statins. In their paper appearing in the July 15 issue of JAMA, a team led by Massachusetts General Hospital (MGH) ...
An examination of the 2013 guidelines for determining statin eligibility, compared to guidelines from 2004, indicates that they are associated with greater accuracy and efficiency in identifying increased risk of cardiovascular disease (CVD) events and presence of subclinical coronary artery disease, particularly in individuals at intermediate risk, according to a study in the July 14 issue of JAMA.
The 2013 American College of Cardiology/American Heart Association (ACC/AHA) guidelines for the management of blood cholesterol represent a shift in the treatment approach ...
A microsimulation model-based analyses suggests that the health benefits associated with the 10-year atherosclerotic cardiovascular disease risk threshold of 7.5 percent or higher used in the 2013 ACC-AHA cholesterol guidelines are worth the additional costs required to achieve these health gains, and that a more lenient threshold might also be cost-effective, according to a study in the July 14 issue of JAMA.
In November 2013 the American College of Cardiology and the American Heart Association (ACC/AHA) released new recommendations to guide statin treatment initiation ...
