Assessing homeopathic proving using questionnaire methodology: consideration and implications for future studies
No full textHomeopathic pathogenetic trials (or provings) provide the foundations for the clinical practice of homeopathy. The most recent review of proving studies indicated that provings are generally of poor methodological quality. Methods to improve the quality and scientific rigour are needed to critically assess the clinical basis of homeopathy. This article describes a methodology using a symptom diary with a selection of predefined remedy specific symptoms (proving questionnaire). The proving questionnaire was developed as an alternative to the traditional qualitative proving methods in an attempt to provide a quantitative method that could rigorously validate the original provings. This article considers the advantages and disadvantages of this approach and provides suggestions for future work in this area
Devil's Claw (Harpagophytum procumbens) as a treatment for osteoarthritis: a review of efficacy and safety
No full textBACKGROUND: Osteoarthritis (OA) is a highly prevalent musculoskeletal disorder. Conventional treatment (i.e., the use of nonsteroidal anti-inflammatory drugs-NSAIDs) is associated with well-documented adverse effects. Devil's Claw (Harpagophytum procumbens) a traditional South African herbal remedy used for rheumatic conditions, may be a safer treatment option. To date, 14 clinical trials have assessed its efficacy/ effectiveness in OA. AIM: To address the two main questions of importance to clinicians: (1) Does Devil's Claw work for the treatment of OA, and (2) Is it safe? METHODS: A review of the literature on Devil's Claw and OA from 1966 to 2006 was performed using multiple search databases, monographs, and citation tracking. Relevant trials in all languages were identified and included. Both internal validity (i.e., adequacy of the dosage and period of treatment for this condition, reporting of randomization, rates of dropout, blinding, and statistical analysis) and external validity (i.e., inclusion/ exclusion criteria, baseline characteristics of the study populations, trial setting, and the appropriateness of the outcome measures of the trials) were assessed. RESULTS: Fourteen studies were identified: eight observational studies; 2 comparator trials (1 open, the other randomized to assess clinical effectiveness); and 4 double-blinded, placebo-controlled, randomized controlled trials to assess efficacy. Many of the published trials lacked certain important methodological quality criteria. However, the data from the higher quality studies suggest that Devil's Claw appeared effective in the reduction of the main clinical symptom of pain. The assessment of safety is limited by the small populations generally evaluated in the clinical studies. From the current data, Devil's Claw appears to be associated with minor risk (relative to NSAIDs), but further long-term assessment is required. CONCLUSIONS: The methodological quality of the existing clinical trials is generally poor, and although they provide some support, there are a considerable number of methodologic caveats that make further clinical investigations warranted. The clinical evidence to date cannot provide a definitive answer to the two questions posed: (1) Does it work? And (2) is it safe? A definitive high-quality trial that addresses the necessary methodologic improvements noted is needed to answer these important clinical questions
Tryptophan metabolism during the menstrual cycle
No full textThe metabolism of tryptophan and tryptophan metabolites was investigated during the follicular, luteal and premenstrual phases of the menstrual cycle in 33 healthy women across one cycle. The metabolites of all three pathways of tryptophan ie the serotonergic pathway, the pyrollase pathway and the indole acetic acid pathway, were assayed from urinary prebreakfast samples collected on a repeated measures basis. Urinary 3 hydroxy kynurenine excretion was significantly elevated in the luteal phase (p=0.030). The relative activity of the serotonergic pathway to the kynurenergic pathway (identified by the ratios 5HT+HIAA/KY+HK and 5HT/KY+HK) were significantly elevated in both the luteal and premenstrual phases compared to the follicular phase (p=0.009 and p=0.005 respectively); indicating that the kynurenergic pathway of tryptophan metabolism may modulate serotonergic metabolism (via HK) during the menstrual cycle; and that the relative and not actual levels of serotonin metabolism may be the important factor when investigating any cyclical effects of the neurotransmitter serotonin
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
