A book of ideas collected from Medical Hypotheses: Death can be cured by Roger Dobson

A new collection of ideas from Medical Hypotheses by Roger Dobson is entitled Death can be cured and 99 other Medical Hypotheses. It consists of humorous summaries of Medical Hypotheses articles from the past 30 years. The book's humour derives mainly from the subject matter, although sometimes also from the 'unconventional' approach of the authors with respect to matters such as evidence, argument or inference. Medical Hypotheses has generated such a lot of apparently- or actually-bizarre ideas because it aims to be open to potentially revolutionary science. The journal's official stance is that more harm is done by a failure to publish one idea that might have been true, than by publishing a dozen ideas that turn out to be false. Bizarre ideas tend to catch attention, and may stimulate a valuable response--even when a paper is mostly-wrong. A paper may be flawed but still contain the germ of an idea that can be elaborated and developed. The journal review process is susceptible to both false positives and false negatives. False positives occur when we publish an idea that is wrong; false negatives occur when we fail to publish an important idea that is right, and a potential scientific breakthrough never happens. False positives are more obvious, since the paper will be ignored, refuted, or fail to be replicated--and often attracts criticism and controversy. Editors may therefore take the more cautious path of avoiding false positives more assiduously than false negatives; however, this policy progressively favours less-ambitious science. Consequently, in Medical Hypotheses the 'set point' of risk is nearer to the false positive end of the spectrum than for most journals - and the publication of many apparently-bizarre papers is a natural consequence of this policy.

A multicenter two by two factorial trial of cognitive behavioral therapy and aerobic exercise for Gulf War veterans' illnesses: design of a veterans affairs cooperative study (CSP #470)

The Department of Veterans Affairs (VA) Cooperative Studies Program (CSP) Study #470 is a 2 x 2 factorial trial designed to evaluate the hypothesis that both cognitive behavioral therapy (CBT) and aerobic exercise will significantly improve physical function in participants with Gulf War veterans' illnesses (GWVI), and that adding CBT to aerobic exercise will provide further incremental benefit. One thousand three hundred fifty-six veterans will be randomized to one of four treatment arms: CBT plus aerobic exercise plus usual and customary care, aerobic exercise plus usual and customary care, CBT plus usual and customary care, or usual and customary care alone. The study duration is 2.5 years with 1.5 years of intake and 1 year of follow-up. The primary outcome measure is the proportion of veterans improved more than seven units on the physical component summary (PCS) scale of the Short Form Health Survey for Veterans (SF-36V) measured 12 months after randomization. This generic quality-of-life measure was chosen because there is no disease-specific measure for GWVI and the symptoms of GWVI span a wide range of physical manifestations that are related to the domains covered by the PCS scale. Sample size was determined to detect all six pairwise comparisons between the four treatment arms with 90% power and a Bonferroni adjustment for an overall type I error of 0.05 or 0.05/6 = 0.0083. CSP #470 was initiated in May 1999 in 18 VA and two Department of Defense medical centers. To date this represents the largest randomized trial designed to evaluate treatments for individuals with unexplained physical symptoms. This paper will focus on the rationale and unique features of the study design. Control Clin Trials 2001;22:310-332

Rehabilitative care of war-related health concerns

The objective of this study was to pilot the effectiveness of a 3-week rehabilitative intervention that used medical review, graded exercise, education on Gulf War exposures, active coping, and nutrition to improve disability and related distress for Gulf War veterans with persistent symptoms. One hundred and nine veterans were assessed at program entry and exit and at 1 and 3 months after program completion. Outcomes were physical symptoms, quality of life, physical health concern, and psychosocial distress--contrasted across time and demographic groups. After treatment, veterans showed modest and global improvements; women were more likely than men to show improvement. The finding that Gulf War veterans who completed specialized rehabilitative management experienced modest, short-term improvements is encouraging, given that veterans of the conflict remain concerned about their future health. Controlled studies are needed.
