How scientific is the science in ethnopharmacology? Historical perspectives and epistemological problems

This commentary is based on a general concern regarding the low level of self-criticism (-evaluation) in the interpretation of molecular pharmacological data published in ethnopharmacology-related journals. Reports on potentially new lead structures or pharmacological effects of medicinal plant extracts are mushrooming. At the same time, nonsense in bioassays is an increasing phenomenon in herbal medicine research. Only because a dataset is reproducible does not imply that it is meaningful. Currently, there are thousands of claims of pharmacological effects of medicinal plants and natural products. It is argued that claims to knowledge in ethnopharmacology, as in the exact sciences, should be rationally criticized if they have empirical content as it is the case with biochemical and pharmacological analyses. Here the major problem is the misemployment of the concentration-effect paradigm and the overinterpretation of data obtained in vitro. Given the almost exponential increase of scientific papers published it may be the moment to adapt to a falsificationist methodology.

Factors influencing the quality of the consultation process

Sport psychology services have become to be an important brick stone when building athletic success. The strive for better performance is not only a characteristic of athletes, but of the whole support system in top level sport including sport psychology. Sport psychology consultants are permanently challenged to deliver highest quality services to their clients if they do not want to lose their contracts. Sport psychologists are continuously improving their consulting skills, learn new intervention techniques, read scientific papers and, last but not least, gain experience by accumulating hours of deliberate practice (Ericsson) in sport psychology. Even with increasing experience, the consultant has a certain number of degrees of freedom and has to make a series of decisions about how he or she wants to work. Quality, however, depends on a number of issues, and not all of them are under direct control of the consultant. It is argued that, in order for these choices being good, the following factors - among others - must be considered: Who is seeking assistance? What are the "issues and problems" (Gardner & Moore, 2006) the athlete is confronted with? What kind of approaches do fit with the client's need? Who is the 'client' the sport psychologist is supposed to work with? If it is a team, is the sport psychologist supposed to work with a number of individuals, with the coach, or with the whole system? Where are the boundaries of the system? What is the role of the sport psychologist in the sport system? All these issues directly affect the process and outcome quality of the sport psychology consultant. A sound theoretical basis, in connection with a distinct philosophy of the intervention, is an important cornerstone for the quality of sport psychology consultation.

Internet-Based Treatments - Experiences from Sweden. An Interview with Gerhard Andersson

Worldwide, Gerhard Andersson is one of the most influential researchers working on internet-based psychological treatments. Moreover, he is also one of the leading researchers in the field of psychologically oriented tinnitus research. He is full professor of clinical psychology at Linköping University and affiliated professor at the Karolinska Institute in Stockholm at the Department of Clinical Neuroscience, Section Psychiatry. Professor Andersson has been highly productive, having produced more the 300 scientific papers. During his whole career he has worked part-time with patients. Apart from his own research and clinical work, Professor Andersson has editorial responsibilities for several journals including Cognitive Behaviour Therapy, Plos One, BMC Psychiatry, and Scandinavian Journal of Psychology. The interview was conducted by Professor Thomas Berger.

The hundred most cited articles in bariatric surgery

BACKGROUND Many studies quantitatively analyzing scientific papers have appeared in the last 2 years. Citation analysis is a commonly used bibliometric method. In spite of some limitations, it remains a good measure of the impact an article has on a specific field, specialty, or a journal. The aim of this study was to analyze the qualities and characteristics of the 100 most cited articles in the field of bariatric surgery. METHODS The Thomson Reuters Web of Knowledge was used to list all bariatric surgery-related articles (BSRA) published from 1945 to 2014. The top 100 most cited BSRA in 354 surgical and high impact general journals were selected for further analysis. RESULTS Most of the articles were published in the 2000s (60%). The top 100 most cited were published in 17 of the 354 journals. Leading countries were USA followed by Canada and Australia. Most of the articles published (76%) were clinical experience articles. The most common level of evidence was IV (42%). CONCLUSIONS Many of the milestone papers in bariatric surgery have been included in this bibliometric study. A huge increase in research activity during the last decade is clearly visible in the field. It is apparent that the number of citations of an article is not related to its level of evidence; a fact that is increasingly being emphasized in surgical research.

Lost in translation: the impact of publication language on citation frequency in the scientific dental literature

Citation metrics are commonly used as a proxy for scientific merit and relevance. Papers published in English, however, may exhibit a higher citation frequency than research articles published in other languages, though this issue has not yet been investigated from a Swiss perspective where English is not the native language.

Scientific assembly update: paediatrics in Vienna

The aim of this update is to describe, in the context of the current literature, major papers from the seven groups of the Paediatric Assembly (Respiratory Physiology; Asthma and Allergy; Cystic Fibrosis; Respiratory Infection and Immunology; Neonatology and Paediatric Intensive Care; Respiratory Epidemiology; and Bronchology) presented during the European Respiratory Society's annual meeting held in 2012 in Vienna, Austria.
