1. Other published trials comparing nicotine patch with placebo (not analysedhere because their follow up was shorter than six months) had early resultssimilar to the six trials included in this analysis.

2. The direct effects of nicotine in increasing blood pressure and heart rate areshort term and shared by many common activities not regarded ashazardous.

3. Also, smoking a cigarette does not commonly precipitate angina in patientswith coronary artery disease.

4. In any case the use of nicotine chewing gum (4 mg) has a smaller effect onblood pressure and heart rate than cigarette smoking.

5. If there is hazard at all it must be smaller than that of continuing to smoke.6. Nicotine dependent patients who are motivated but have not succeeded in

stopping smoking without nicotine replacement can be advised to use this

therapy.7. Nicotine replacement therapy overall could enable about 15% of smokers who are motivated to seek help to give up smoking - a useful effect inovercoming a lethal habit.

8. Bioengineering advances the nation's health by increasing biologicalknowledge through the use of engineering principles and techniques andcontributes methods that have facilitated the development of novel devicesand drugs.

9. To address current needs and prepare for the future of this emerging area, Iam establishing an NIH bioengineering consortium.

10. BECON meetings will identify major issues and establish small workinggroups, each led by a BECON representative and including individuals withappropriate expertise.

11. Panels discussed the role of biomedical engineering in addressing thesechallenges and proposed recommendations for future NIH activities.

12. He emphasised the importance of increased funding by the NIH forbioengineering.

13. Panels, dealing with a broad range of biomedical engineering researchareas discussed the obstacles to addressing future research needs andmade recommendations for areas of investment and for means toimplement the recommendations.

14. New developments are providing crucial information and essentialapproaches for understanding the structure and function of cells andmolecules.

15. The emergent microscopies are particularly critical in research onmechanical modelling of cells and tissues, interactions of implanted deviceswith host tissues, biosensors that monitor physiological processes, andprosthetics to augment deficient sensory systems.

16. Diagnostic imaging of tissues and organs, especially in the modalities ofultrasound, nuclear medicine, nuclear magnetic resonance andspectroscopy, and X-ray computed tomography, has been a field of rapidadvances.

17. The NIH can facilitate achievement of this goal by supporting themultidisciplinary research necessary to develop instruments and devicesfor the next century.

18. Improvements in preventive, diagnostic, and therapeutic medicine requirethe ongoing infusion of new technologies (drugs, devices, equipment and

procedures) evolving from discovery and knowledge gained through basicbiomedical research.

19. Nurturing this migration to stimulate productive research and improveclinical medicine is an ever-present challenge for the NIH.

20. Nanobiotechnology will generate new capabilities, facilities, andapproaches for investigating and understanding cellular and molecularprocesses.

21. Biochemical modeling is a glue holding together various experimental andinterpretative modalities.

22. Both fields involve acquiring, processing, and analysing information.23. Biomechanics is a branch of engineering science dealing with the

involvement of force, deformation and motion in biology, from molecules towhole individuals.

24. Diseases involving electrical dysfunction in the heart, brain, and skeletalmuscles are major health problems.

25. In the hernia programme the sound is of patchy quality, varying in clarityand amplitude.

26. The teaching of operative surgery will almost certainly involve computerbased learning packages such as these.

27. At present, they are limited in scope and expensive, and most trainees areunlikely to find them more useful than the traditional combination of a

textbook of operative surgery and a period of supervised training in theoperating theatre.

28. To conduct a systematic review of the efficacy and safety of exogenousmelatonin in managing secondary sleep disorders and sleep disordersaccompanying sleep restriction, such as jet lag and shiftwork disorder.

29. A sleep disorder exists whenever a lower quality of sleep leads to impairedfunctioning or excessive sleepiness.

30. Our findings can help to guide clinicians and patients in treatment decisionsregarding the use of exogenous melatonin in the management of theseconditions.

31. Continuous outcomes were combined, using a weighted mean difference,with the exception of sleep quality, for which studies were combined byusing a standardised mean difference.

32. A point estimate with corresponding 95% confidence interval wascomputed for each outcome.

33. Regarding the effect of allocation concealment on effect estimates, failure toconceal treatment allocation adequately is associated with larger effectestimates.

34. Two other systematic reviews examining the use of melatonin for jet lagconcluded that melatonin is effective in alleviating the symptoms of jet lag.

35. The MRC's chief executive, Colin Blakemore, announced on Monday that a

team of senior scientists, including the MRC's influenza expert John Skehel,would be visiting China, Vietnam, and Hong Kong.

36. The proportion of rehabilitation patients requiring subsequent surgerycontinues to increase.

37. Chronic low back pain, defined as pain lasting for more than three months,is common and places a major economic burden on individuals, thehealthcare system, and society as a whole.

38. The chosen form of analysis will facilitate comparisons between the costeffectiveness of surgery and that of other healthcare interventionscompeting for healthcare resources.

39. Rehabilitation patients attended a paced exercise and educationprogramme based on principles of cognitive behaviour therapy totallingabout 75 hours.

40. We used unit costs obtained from the lead investigating centre to valuetypes and numbers of surgical implants and intraoperative spinal x rays.
