Piper betle induces phase I & II genes through Nrf2/ARE signaling pathway in mouse embryonic fibroblasts derived from wild type and Nrf2 knockout cells.
Nuclear factor-erythroid 2 p45 related factor 2 (Nrf2) is a primary transcription factor, protecting cells from oxidative stress by regulating a number of antioxidants and phase II detoxifying enzymes. Dietary components such as sulforaphane in broccoli and quercetin in onions have been shown to be inducers of Nrf2. Piper betle (PB) grows well in tropical climate and the leaves are used in a number of traditional remedies for the treatment of stomach ailments and infections among Asians. The aim of this study was to elucidate the effect of Piper betle (PB) leaves extract in Nrf2 signaling pathway by using 2 types of cells; mouse embryonic fibroblasts (MEFs) derived from wild-type (WT) and Nrf2 knockout (N0) mice. ⋯ The results of this study confirmed that PB activated Nrf2-ARE signaling pathway which subsequently induced some phase I oxidoreductase, phase II detoxifying and antioxidant genes expression via ARE reporter gene involved in the Nrf2 pathway with the exception of SOD1 which may not be dependent on this pathway.

Questions about complementary and alternative medicine to the Regional Medicines Information and Pharmacovigilance Centres in Norway (RELIS): a descriptive pilot study.
Provision of clinically relevant information about complementary and alternative medicine (CAM) to health care professionals is not well described. The aim of the study was to assess questions about CAM to the Regional Medicines Information and Pharmacovigilance Centres in Norway (RELIS). ⋯ General practice and community pharmacies are the main sources for questions about CAM to RELIS. Physicians are concerned about adverse effects while pharmacists are concerned about interactions. Lack of information to provide answers to patient-specific and general questions about CAM represents a problem.

Randomized Controlled TrialHow mindfulness changed my sleep: focus groups with chronic insomnia patients.
Chronic insomnia is a major public health problem affecting approximately 10% of adults. Use of meditation and yoga to develop mindful awareness ('mindfulness training') may be an effective approach to treat chronic insomnia, with sleep outcomes comparable to nightly use of prescription sedatives, but more durable and with minimal or no side effects. The purpose of this study was to understand mindfulness training as experienced by patients with chronic insomnia, and suggest procedures that may be useful in optimizing sleep benefits. ⋯ First-person accounts are consistent with published trial results of positive impacts of MBSR on sleep measured by sleep diary, actigraphy, and self-report sleep scales. Findings indicate that mindfulness training in a group format, combined with sleep hygiene education, is important for effective application of MBSR as a treatment for chronic insomnia.

LetterHigh prevalence but limited evidence in complementary and alternative medicine: guidelines for future research.
The use of complementary and alternative Medicine (CAM) has increased over the past two decades in Europe. Nonetheless, research investigating the evidence to support its use remains limited. The CAMbrella project funded by the European Commission aimed to develop a strategic research agenda starting by systematically evaluating the state of CAM in the EU. ⋯ A European Centre for CAM should also be established to monitor and further a coordinated research strategy with sufficient funds to commission and promote high quality, independent research focusing on the public's health needs and pan-European collaboration. There is a disparity between highly prevalent use of CAM in Europe and solid knowledge about it. A strategic approach on CAM research should be established to investigate the identified gaps of knowledge and to address upcoming health care challenges.

Cognitive interviews guide design of a new CAM patient expectations questionnaire.
No consistent relationship exists between pre-treatment expectations and therapeutic benefit from various complementary and alternative medicine (CAM) therapies in clinical trials. However, many different expectancy measures have been used in those studies, with no validated questionnaires clearly focused on CAM and pain. We undertook cognitive interviews as part of a process to develop and validate such a questionnaire. ⋯ Cognitive interviews identified wordings with considerable agreement among both participants and investigators. Some items widely used in clinical studies had different meanings to participants than investigators, or were confusing to participants. The final 18-item questionnaire is undergoing psychometric evaluation with goals of streamlining as well as identifying best items for use when questionnaire length is constrained.
