Abstract: Ethnopharmacological relevance: In the traditional context, herbs are often used as herbal whole system therapies, however, most clinical trials included highly selected patients and applied standardized treatment protocols with the aim to exclude as much bias as possible. These studies have contributed important information on the efficacy of herbal medicine extracts; however, their results are only marginally helpful to understand the value of herbal medicine and food items in a more traditional usual care context. Methods: The new development of comparative effectiveness research (CER) will be introduced and synergies with ethnopharmacology will be outlined. Results: CER provides great opportunities for guiding researchers and clinicians in improving management of disease. CER compares two or more health interventions in order to determine which of these options works best for which types of patients in settings that are similar to those in which the intervention will be used in practice. CER uses a broad spectrum of methodologies including randomized pragmatic trials that can also be applied to herbal whole system therapies. Ethnopharmacological research can provide highly relevant information for CER including data on characteristics of typical patients as well as traditional usage including methods of collection, extraction, and preparation. Recommendations for future research on traditional herbal medicine and food items are (1) a systematic cooperation between ethnopharmacology and clinical researchers and (2) a call for more CER on traditional herbal medicines and food items. Conclusion: Multiple stakeholders, including ethnopharmacologists, should cooperate to identify relevant study questions as well share their knowledge to determine the optimal placement of a clinical trial in the efficacy–effectiveness–continuum.

To examine the effects of six relaxation techniques on perceived momentary relaxation and a possible association of relaxation effects with time and practice experience in people with cancer. We used data from participants with cancer in a larger study practicing app-based relaxation techniques over 10 weeks, assessed momentary relaxation before and after every third relaxation practice, and analyzed momentary relaxation changes with a linear mixed-effects model. The sample included 611 before-after observations from 91 participants (70 females (76.9%)) with a mean age of 55.43 years (SD 10.88). We found moderate evidence for variations in momentary relaxation changes across different techniques (P =.026), with short meditation, mindfulness meditation, guided imagery, and progressive muscle relaxation more frequently observed and leading to more relaxation than body scan and walking meditation. Furthermore, we found moderate evidence for increasing momentary relaxation changes over time (P =.046), but no evidence for an association between momentary relaxation and the number of previous observations (proxy for practice experience; P =.47). We compared six app-based relaxation techniques in a real-life setting of people with cancer. The observed variations in perceived momentary relaxation appear to correspond with the popularity of the techniques used: The most popular relaxation techniques were the most effective and the least popular were the least effective. The effects increased over time, likely caused by dropout of individuals who gained no immediate benefit. Our findings open an interesting avenue for future research to better understand which relaxation techniques work best for whom in which situations. DRKS00027546; https://drks.de/search/en/trial/DRKS00027546 • Relaxation techniques can reduce cancer-related distress in the long term. • It is unclear if relaxation techniques give immediate benefit to people with cancer. • We show that different relaxation techniques have different immediate effects. • Popular relaxation techniques relax people with cancer, unpopular techniques do not. • Relaxation apps should offer a variety of relaxation techniques to choose from.

Objective: Some people might be more prone to placebo and nocebo responses than others depending on their personality traits. We aimed to provide a systematic review on the influence of personality traits on placebo and nocebo responses in controlled and uncontrolled studies.Methods: We conducted a systematic literature search in the databases CINAHL, AMED, PsycINFO and EMBASE for relevant publications published between January 1997 and March 2018. For all included papers, we conducted an additional forward search.Results: After screening 407 references, we identified 24 studies. The Big Five (i.e., neuroticism, extraversion, openness to experience, agreeableness and conscientiousness) and optimism were the most frequently investigated personality traits. Several studies found a positive association between optimism and the placebo response. Furthermore, we found that higher anxiety was associated with increased nocebo responses.Conclusion: Evidence points to a possible association between optimism and the placebo response. Therefore, further emphasising the investigation of the influence of optimism on the placebo/nocebo response seems warranted. For clinical practice, the impact of anxiety on the nocebo response might be important to identify patients who might be more prone to experiencing side effects of medical treatments.

Abstract Ethnopharmacological relevance Passiflora incarnata Linnaeus (Passiflora incarnata) was established as a medicinal plant in Europe in the middle of the 19th century. Since then, it has been used for the treatment of anxiety, sleep disorders and restlessness in Western European phytotherapy. This study provides insights into how Passiflora incarnata is currently used and experienced as a medicinal plant by German-speaking patients in Switzerland. Aim This qualitative study aimed to explore patients' experiences and the values, views and interpretive processes that formed their perceptions of the use of an ethanolic extract of Passiflora incarnata. Methods A total of 8 patients participated in this exploratory, qualitative observational study. The patients filled in pre- and posttreatment questionnaires, kept diaries and were interviewed in a face-to-face setting. For the data analysis, descriptive statistics, qualitative content analysis, narrative inquiry and documentary methods were applied. Results This is the first qualitative study of patients' real-life experiences with an ethanolic extract of Passiflora incarnata. We identified three distinct types of patient biographical narratives attributed to different experiences when using Passiflora incarnata. Patients with type 1 narratives described moving from a performance orientation to resetting priorities and attaining calmness. Patients with type 2 narratives maintained a performance orientation while adopting calmness. Patients with type 3 narratives maintained a performance orientation and suffered from persistent illness. Conclusion The distinct biographical narratives of the patients associated with their specific experiences of taking Passiflora incarnata provide an additional perspective on the use of Passiflora incarnata as a medicinal plant.

Context: Chinese medicine modalities, including acupuncture and Chinese herbal medicine (CHM), have been used as palliative interventions among cancer patients. More research should be conducted to confirm their effectiveness.Objectives: The objective of this study was to prioritize Chinese medicine clinical research questions for cancer palliative care.Methods: Twelve international experts, including physicians, Chinese medicine practitioners, nurses, and clinical research methodologists (n = 3 from each category), from Asia, North America, Australia, and Europe participated in a two-round Delphi survey for prioritizing 29 research questions identified from existing systematic reviews. The experts were asked to 1) rate clinical importance of answering the questions on a nine-point Likert scale; 2) provide qualitative comments on their ratings; and 3) suggest outcome measurement approaches.Results: Eight research priorities reached positive consensus after the two-round Delphi survey. Six of the priorities focused on acupuncture and related therapies, of which median ratings on importance ranged from 7.0 to 8.0 (interquartile range: 1.00 to 2.50), and the percentage agreement ranged from 75.0% to 91.7%. The remaining two priorities related to CHM, with median ratings ranged from 7.0 to 8.0 (interquartile range: 1.00 to 1.50) and percentage agreement ranged from 75.0% to 83.3%. Neither positive nor negative consensus was established among the remaining 21 questions.Conclusion: The findings will inform rational allocation of scarce research funding for evaluating the effectiveness of Chinese medicine for cancer palliative care, especially on acupuncture and related therapies. Further research on herb safety and herb-drug interaction should be performed before conducting international trials on CHM. [ABSTRACT FROM AUTHOR]
