Item Effects of a Delphi consensus acupuncture treatment protocol on the levels of stress and vascular tone in women undergoing in-vitro fertilization: A randomized clinical trial protocol(2017) Zhang, Yan (TTUHSC); Phy, Jennifer (TTUHSC); Scott-Johnson, Chris (TTUHSC); Garos, Sheila (TTU); Orlando, Jennie (TTUHSC); Prien, Samuel (TTUHSC); Huang, Jaou Chen (TTUHSC)Background: The variability of published acupuncture protocols for patients undergoing In-Vitro Fertilization (IVF) complicates the interpretation of data and hinders our understanding of acupuncture's impact. In 2012, an acupuncture treatment protocol developed by a Delphi consensus process was published to describe the parameters of best practice acupuncture for Assisted Reproductive Technology and future research. However, there has been no clinical trial utilizing this protocol to assess the effects of acupuncture. This study aims to assess the implementation of Dephi consensus acupuncture protocol and to examine the impact of acupuncture on stress and uterine and ovarian blood flow among women between ages 21-42 years seeking IVF. Methods/Design: This study is a one site prospective, two-arm randomized controlled non-blind clinical trial conducted in a medical school-affiliated fertility center. Participants will be randomized 1:1 into either the acupuncture group or the standard of care (no acupuncture) group using computer generated tables. Both groups will have 3 regular clinical visits as their standard IVF care during an approximately 2 to 3 weeks window. Women who are randomized into the acupuncture group would receive three sessions based on the Delphi consensus acupuncture protocol in addition to the standard care. The first treatment will be administered between days 6 to 8 of the stimulated IVF cycle. The second session will be performed on the day of embryo transfer at least 1 h prior to the transfer. The third session will be performed within 48 h post-embryo transfer. Participants will be followed for their pregnancy test and pregnancy outcome when applicable. The outcomes stress and blood flow will be measured by a validated perceived stress scale and vasoactive molecules, respectively. Discussion: Although recruitment and scheduling could be challenging at times, the Delphi consensus acupuncture protocol was implemented as planned and well-accepted by the patients. Because of the time-specified sessions around patients' IVF cycle, it is highly recommended to have on-site study acupuncturist(s) to accommodate the schedule.

(TTUHSC); Yeh, James K.; Zhang, Yan (TTUHSC); Felton, Carol K. (TTUHSC); Doctolero, Susan (TTUHSC); Wang, Jia ShengBackground: Evidence suggests that both green tea polyphenols (GTP) and Tai Chi (TC) exercise may benefit bone health in osteopenic women. However, their safety in this population has never been systematically investigated. In particular, there have been hepatotoxicity concerns related to green tea extract. This study was to evaluate the safety of 24 weeks of GTP supplementation combined with TC exercise in postmenopausal osteopenic women, along with effects on quality of life in this population.Methods: 171 postmenopausal women with osteopenia were randomly assigned to 4 treatment arms for 24 weeks: (1) Placebo (500 mg starch/day), (2) GTP (500 mg GTP/day), (3) Placebo + TC (placebo plus TC training at 60 min/session, 3 sessions/week), and (4) GTP + TC (GTP plus TC training). Safety was examined by assessing liver enzymes (aspartate aminotransferase, alanine aminotransferase), alkaline phosphatase, and total bilirubin at baseline and every 4 weeks. Kidney function (urea nitrogen and creatinine), calcium, and inorganic phosphorus were also assessed at the same times. Qualify of life using SF-36 questionnaire was evaluated at baseline, 12, and 24 weeks. A mixed model of repeated measures ANOVA was applied for analysis.Results: 150 subjects completed the study (12% attrition rate). The compliance rates for study agents and TC exercise were 89% and 83%, respectively. Neither GTP supplementation nor TC exercise affected liver or kidney function parameters throughout the study. No adverse event due to study treatment was reported by the participants. TC exercise significantly improved the scores for role-emotional and mental health of subjects, while no effect on quality of life was observed due to GTP supplementation.Conclusions: GTP at a dose of 500 mg/day and/or TC exercise at 3 hr/week for 24 weeks appear to be safe in postmenopausal osteopenic women, particularly in terms of liver and kidney functions. TC exercise for 24 weeks (3 hr/wk) significantly improved quality of life in terms of role-emotional and mental health in these subjects. © 2010 Shen et al; licensee BioMed Central Ltd.
