Nevasic HONcode Compliance

Health On The Net Foundation

Health On the Net Foundation’s origins go back to September 7-8, 1995, when some of the world’s foremost experts on telemedicine gathered in Geneva, Switzerland, for a conference entitled “The Use of the Internet and World-Wide Web for Telematics in Healthcare” .

The 60 participants came from 11 countries. They included U.S. heart surgeon Dr Michael DeBakey, physicians and professors, researchers and senior representatives of the World Health Organisation (WHO), International Telecommunication Union (ITU), the European Laboratory for Particle Physics (CERN), the European Commission, the National Library of Medicine and the G7-Global Healthcare Applications Project.

As the conference wound up, they unanimously voted to create a permanent body that would, in the words of the programme, “promote the effective and reliable use of the new technologies for telemedicine in healthcare around the world. HON’s site went live some six months later. On March 20, 1996, became one of the very first URLs to guide both lay users and medical professionals to reliable sources of healthcare information in cyberspace.”

Motion or “Travel” Sickness

In the case of statements made in relation to Travel Sickness:

Research in the form of a clinical trial carried out by Westminster College of Medicine;

Journal of Travel Medicine – Volume: 10 • Issue: 02 • 2003 • March • Page: 108

Behavioural Methods of Alleviating Motion Sickness: Effectiveness of Controlled Breathing and a Music Audiotape:

Fleur D.Yen Pik Sang, Jessica P. Billar, John F. Golding, and Michael A. Gresty, Jessica P. Billar, John F. Golding: Department of Psychology, University of Westminster, London; Fleur D. Yen Pik Sang, Michael A. Gresty: MRC Spatial Disorientation Group, Imperial College School of Medicine, London, United Kingdom.


Background: Behavioural countermeasures for motion sickness would be advantageous because of the side effects of antiemetic drugs, but few alternative treatments are available. The objective of this study was to compare the effectiveness of controlling breathing and listening to a music audiotape designed to reduce motion sickness symptoms, on increasing tolerance to motion-induced nausea.

Method: Twenty-four healthy subjects were exposed to nauseogenic Coriolis stimulation on a rotating turntable under three conditions: whilst focusing on controlling breathing; listening to a music audiotape; or without intervention (control). The three conditions were performed by each subject according to a replicated factorial design at 1-week intervals at the same time of day. Ratings of motion sickness were obtained every 30 seconds. Once a level of mild nausea was reached subjects commenced controlling breathing or listened to the music audiotape. Motion was stopped after the onset of moderate nausea.

Results: Mean (± SD) motion exposure time in minutes tolerated before the onset of moderate nausea was significantly longer (p < .01) for controlling breathing (10.7 ± 5.6 min) and longer (p < .01) for music (10.4 ± 5.6 min) compared with control (9.2 ± 5.9 min).

Conclusions: Both controlling breathing and the music audiotape provided significant protection against motion sickness and with similar effectiveness. These nonpharmacologic countermeasures are only half as effective as standard doses of antimotion sickness drugs, such as oral scopolamine; however, they are easy to implement and free of side effects.

A sound remedy?A new treatment for ‘Morning Sickness’

Lynne Mayo and her colleagues at the Andover Birth Centre were sceptical about the benefits of an audio tape – but now they’re impressed.Lynne Mayo SRN. SCM. is a Community and Birth Centre Midwife based at Andover Birth Centre.

HOW OFTEN DO WE SEE the elation of pregnancy diminished by the distress of “morning sickness” Nausea and vomiting in pregnancy (NVP) is non-specific, it affects approx. 80% of pregnant women[1], and the range of symptoms extend from mild nausea through to the extreme of Hyperemesis Gravidarum[2]. It can last all day, it can keep recurring in waves. The actual aetiology is still unclear and there are various theories but NVP is mainly attributed to altered hormone function, physiological and metabolic changes and genetic incompatibility [3]. This preliminary study introduces the ‘Morning Well tape’ in to the lives of pregnant women and exciting initial findings have shown a marked reduction of symptoms.

“I can’t eat anything” “I feel wretched” “I’m nauseated all the time” “I can’t cope with the family” “I can’t get out of bed and I’ve never been ill in my life” I’m struggling to be at work” etc. These words are so familiar, and what is our response? Sympathy. Whitehead SA, Andrews PLR, Chamberlain GVP 2. Lacroix R, Easton E, Melzack R. Nausea and vomiting during pregnancy 3. Lindsay P. Vomiting.In: Sweet B. Mayes Midwifery, 12th edition. London: Bailliere Tindall,1997The MorningWell tape was derived from TravelWell.

TravelWell is a successful travel sickness product, endorsed by Ellen McArthur. It was developed over a number of years, working on the physiology of emesis; there is a recognized correlation between the brain, the vestibular system, and the gut.

[4] The audio tape was devised to react on the vestibular system in such a way that it interrupted the emesis signals to the gut and stopped the sickness. The frequencies and pulses are bordering on our recognisable audio spectrum, but still have a profound effect on the ear. The music overlaying the sounds just makes for more pleasurable listening. It has to be used with a personal stereo. DAVAL, the Andover company responsible, had never thought of the tape being used for anything other than motion sickness, until a couple of women contacted them to ask if it would help in pregnancy, as their symptoms were just the same. DAVAL made no claims at all, but the women used the tape and it worked. Fascinated by this result, DAVAL came to us. It was radical, it was fascinating, and we were cynical!

We looked at the product in depth with safety, the overriding priority. Safety for the woman and the fetus. The tape was non- invasive and under the control of the woman (turned on and off at will). We undertook this preliminary study to find out if this tape worked? In order to do this, we needed to ask the women, and we needed to contact them early enough to offer the tape. Together with DAVAL we devised a questionnaire, which was subsequently passed by the Ethics Committee.


We advertised in GP Surgeries, the local paper, local radio, NCT magazine, that we were running a preliminary study on MorningWell – not that we were endorsing it – but that we were interested in its efficacy. We put a brochure into every booking pack and the midwives offered a free tape if NVP was a problem.

We were all very sceptical, but keen to get the responses. 4. Veyrat-Follet C; Farinotti R; Palmer JL.. Physiology of Chemotherapy-induced emesis and antiemetic therapy. Medline Indexing Date :199706.

Nevasic fatured in the Practical Midwife Journal

As published in:
The Practising Midwife – vol: , No 10: November 2001

This is the one safe option that a midwife can give. We can support and we can acknowledge their distress. As midwives we can recommend ginger, dry biscuits, frequent snacks, Travel bands, and various other helpful hints. All have anecdotal efficacy. Homeopathic, herbal remedies and acupuncture, can only be prescribed by a specialist. There is no evidence based cure for NVP.

The historical evidence with systemic medication (thalidomide) precludes women from wanting to take anything at all, and NVP is a condition that women expect and tolerate.

When the DAVAL Company approached the Andover Birth Centre, late last year, to ask if we would be interested in an audio-tape that might ease morning sickness—we were intrigued. This was a completely new and radical idea. Is it a relaxation tape? Is it subliminal messages—“You will not be sick!” —Is it just pleasant music to take your mind off the nausea? We wanted to know more.


The early feedback from the questionnaires, though positive, showed that there were some difficulties understanding the use of the tape. The programme is made up of 3 phases. The first draws the vestibular system away from the general acoustic and balancing priority, the second is focused on preventing the transmission of the emetic signals to the brain and the gut, and the last phase returns the vestibular system to normal operation. (There have been no reports of any problems with balance). The instructions now highlight the necessity of rewinding the tape prior to each use. It can be used as often as NVP causes a problem, and used from the onset of symptoms for at least 20 mins initially, or until sickness eases or stops.

As we all know, questionnaires are notorious for—getting lost, getting eaten by the dog, left in the rain, drawn on by the toddler, etc., but the women of Andover were very helpful, and the results followed.

150 audio-tapes were offered.

To date we have had 89 questionnaires returned fully completed, 25 fully completed but non-compliant. These returns, we felt couldn’t be in the final numbers, because other remedies had been tried at the same time, i.e. homeopathic remedies, herbal teas, Travel bands etc. 37 questionnaires were not completed for a variety of reasons, the most frequent being that the tape was never used.


The results have been excellent. Originally we thought if it worked for 30% of women that would be amazing. At the time of writing this article it is 90%. The results show that of the 89 women that used the tape appropriately only 3 had no benefit at all. The results to date show that the greatest percentage of efficacy is produced by the 4th day. Some women found no effect the first time, but subsequent usage produced increasingly good effects.


The whole mood of the study has changed. Originally we were all very cynical, and felt that some of the ecstatic responses we received must be due to other reasons but gradually the women’s comments, testimonials, ticks in the box, have made us take it all more seriously. We are now disappointed if the tape fails to ease the symptoms, and try and ensure that the tape is being used in the most beneficial way.

In relation to the information gained from clinical trials with Cancer patients;

The recent clinical using nevasic trial using Nevasic® to assist in dealing with the symptoms of nausea and vomiting in relation to chemotherapy treatment.

The clinical trial was commissioned by National Cancer Research UK, run and managed by “CECO” – a research authority.

Research was instigated by Professor Alex Molassiotis, Professor of Cancer and Supportive Care at the University of Manchester and funding was provided by an independent pharmaceutical company.

The results of this trial are still under review for publication – however there are some startling and pleasing facts to have been passed to us as a result of the research;


The protocol for the trial was prepared by staff of the university under the guidance of the department CECO.

To maintain independence and impartiality DAVAL were not involved in this process or during the course of the trial.

While the results of the trial were not what we were hoping for – they were also not what we were expecting.

This trial highlighted the difficulty in setting up and running a trial of this nature – as the trial was run in Iran.

The key findings highlighted as “commentable” by the trial management are to be construed as positive in that while it was stated by patients that little or no benefit derived from the use of our programme – the amount of follow up care and treatment demanded by that same group was significantly less. This was described by the management as something that could have significant implications from a “cost” perspective – rather than looking purely at the “quality of life” perspective.

A very pleasing note was their comment regarding the side effects…

Key findings are;

  1. No significant differences in nausea/vomiting levels among three groups.
  2. Significant LESS use of antiemetics post-chemo (PRN) in Nevasic group; good and solid result as it has cost implications and less side effects.
  3. Borderline non-significant (p=0.06) better Global Health Status in Nevasic group.
  4. However, shortcomings of data: Nevasic pts had more CINV risk factors and less use of aprepitant (a key primary antiemetic), which may partly explain finding similar levels of CINV in Nevasic and control.

Some good and solid results and some not so good. The imbalance in the study groups in aprepitant use and risk factors makes replication of the study necessary before final conclusions, and possibly use of PRN antiemetics and health care costs being the key outcome to measure.

The social group using Nevasic during their treatment were patients who had undergone mastectomy procedures. We are informed the next trial (under planning now) will be a different niche user group.

Access to the protocol document and chapter 9 interim results can be obtained – after permission is granted by the trial management – you may ask – but you may not receive…just yet…
