Public, Private and University Collaboration: Applying a Retrospective Study of the Central Massachusetts Bio-Medical Cluster, Cluster Project Summary for Mosakowski Institute

Three Clark faculty members are studying the development of the Worcester Biotechnology Cluster for any lessons it might hold for current efforts to catalyze the growth of a sustainable energy/green jobs cluster in Worcester or elsewhere. Mary Ellen Boyle (GSOM), Jennie Stephens (IDCE/ESP), and Jing Zhang (GSOM) have conducted extensive in-depth interviews and combed the literature of cluster development to produce several articles and working papers.

ASSESSING THE UNRELIABILITY OF THE MEDICAL LITERATURE: A RESPONSE TO "WHY MOST PUBLISHED RESEARCH FINDINGS ARE FALSE"

A recent article in this journal (Ioannidis JP (2005) Why most published research findings are false. PLoS Med 2: e124) argued that more than half of published research findings in the medical literature are false. In this commentary, we examine the structure of that argument, and show that it has three basic components: 1)An assumption that the prior probability of most hypotheses explored in medical research is below 50%. 2)Dichotomization of P-values at the 0.05 level and introduction of a “bias” factor (produced by significance-seeking), the combination of which severely weakens the evidence provided by every design. 3)Use of Bayes theorem to show that, in the face of weak evidence, hypotheses with low prior probabilities cannot have posterior probabilities over 50%. Thus, the claim is based on a priori assumptions that most tested hypotheses are likely to be false, and then the inferential model used makes it impossible for evidence from any study to overcome this handicap. We focus largely on step (2), explaining how the combination of dichotomization and “bias” dilutes experimental evidence, and showing how this dilution leads inevitably to the stated conclusion. We also demonstrate a fallacy in another important component of the argument –that papers in “hot” fields are more likely to produce false findings. We agree with the paper’s conclusions and recommendations that many medical research findings are less definitive than readers suspect, that P-values are widely misinterpreted, that bias of various forms is widespread, that multiple approaches are needed to prevent the literature from being systematically biased and the need for more data on the prevalence of false claims. But calculating the unreliability of the medical research literature, in whole or in part, requires more empirical evidence and different inferential models than were used. The claim that “most research findings are false for most research designs and for most fields” must be considered as yet unproven.

Optional course "Homeopathically potentised substances: placebos or effective?" for medical students at the University of Bern, Switzerland

Background Apart from compulsory lectures on classical homeopathy (CH), traditional Chinese medicine/acupuncture, neural therapy and anthroposophically extended medicine (AEM), our institute at the University of Bern offers several optional practical courses for medical students. The aim of this course during autumn 2011 and spring 2012 was to discuss basic research, observational and clinical studies in the fields of CH and AEM, so that students i) learned how to read and appraise scientific publications, ii) learned how complementary medicine can be investigated with scientific methods, and iii) were able to form their own opinion about the possible specific effects and effectiveness of homeopathically potentised substances. Methods Introductory lectures on AEM, CH and study design were given to 12 second year medical students. The students appraised 12 research articles and presented the results in class, followed by discussions with experts in the fields of basic and clinical research from our institute. A company producing homeopathic remedies was visited and students could practise potentization procedures and trituration. At the end of the course, students compiled posters with arguments in favour of and against specific effects and effectiveness as well as their own conclusions. The course was evaluated using a written questionnaire with closed and open questions. Results Previous knowledge about CH and AEM was scarce among the students. It slightly increased during the course, and the course itself fostered their interest on the topic. This course was chosen by most students, because they were genuinely interested in the topic (and not because other courses they had wanted to visit were fully booked). The students especially valued the discussions, the various perspectives presented to them, and experiencing a potentization process. Conclusion Medical students were interested to learn more about homeopathically potentised substances. The contradictory study results made it difficult for them to form their own opinion. Apart from appraising articles, the students would have liked to meet and talk to patients.

Additive homeopathy in cancer patients: Retrospective survival data from a homeopathic outpatient unit at the Medical University of Vienna

Background: Current literature suggests a positive influence of additive classical homeopathyon global health and well-being in cancer patients. Besides encouraging case reports, thereis little if any research on long-term survival of patients who obtain homeopathic care duringcancer treatment. Design: Data from cancer patients who had undergone homeopathic treatment complementaryto conventional anti-cancer treatment at the Outpatient Unit for Homeopathy in MalignantDiseases, Medical University Vienna, Department of Medicine I, Vienna, Austria, were collected,described and a retrospective subgroup-analysis with regard to survival time was performed.Patient inclusion criteria were at least three homeopathic consultations, fatal prognosis ofdisease, quantitative and qualitative description of patient characteristics, and survival time. Results: In four years, a total of 538 patients were recorded to have visited the OutpatientUnit Homeopathy in Malignant Diseases, Medical University Vienna, Department of Medicine I, Vienna, Austria. 62.8% of them were women, and nearly 20% had breast cancer. From the 53.7%(n = 287) who had undergone at least three homeopathic consultations within four years, 18.7%(n = 54) fulfilled inclusion criteria for survival analysis. The surveyed neoplasms were glioblas-toma, lung, cholangiocellular and pancreatic carcinomas, metastasized sarcoma, and renal cellcarcinoma. Median overall survival was compared to expert expectations of survival outcomesby specific cancer type and was prolonged across observed cancer entities (p < 0.001). Conclusion: Extended survival time in this sample of cancer patients with fatal prognosis butadditive homeopathic treatment is interesting. However, findings are based on a small sample,and with only limited data available about patient and treatment characteristics. The relationshipbetween homeopathic treatment and survival time requires prospective investigation in largersamples possibly using matched-pair control analysis or randomized trials.

Analysis of a disaster medical track for the Certificate in Emergency Management and Preparedness Program at the University of Texas at Dallas

Since the tragic events of September 11, 2001, the United States has engaged in building the infrastructure and developing the expertise necessary to protect its borders and its citizens from further attacks against its homeland. One approach has been the development of academic courses to educate individuals on the nature and dangers of subversive attacks and to prepare them to respond to attacks and other large-scale emergencies in their roles as working professionals, participating members of their communities, and collaborators with first responders. An initial review of the literature failed to reveal any university-based emergency management courses or programs with a disaster medical component, despite the public health significance and need for such programs. In the Fall of 2003, The School of Management at The University of Texas at Dallas introduced a continuing education Certificate in Emergency Management and Preparedness Program. This thesis will (1) describe the development and implementation of a new Disaster Medical Track as a component of this Certificate in Emergency Management and Preparedness Program, (2) analyze the need for and effectiveness of this Disaster Medical Track, and (3) propose improvements in the track based on this analysis. ^
