Mindfulness Meditation: A New Treatment for Fibromyalgia?

Science Daily/Psychotherapy and Psychosomatics
Fibromyalgia has emerged as a common, yet difficult to treat disorder. A group of investigators has proposed a new modality of treatment. Mindfulness-based stress reduction (MBSR) proposes a systematic program for reduction of suffering associated with a wide range of medical conditions.
Studies suggest improvements in general aspects of well-being, including quality of life (QoL), coping and positive affect, as well as decreased anxiety and depression. A quasi-experimental study examined effects of an 8-week MBSR intervention among 58 female patients with fibromyalgia (mean, 52 ± 8 years) who underwent MBSR or an active social support procedure.
Three-year follow-up analyses of MBSR participants indicated sustained benefits for these same measures (effect size, 0.50-0.65). Based upon a quasi-randomized trial and long-term observational follow-up, results indicate mindfulness intervention to be of potential long-term benefit for female fibromyalgia patients.

Inflammation in those with PTSD linked to changes in microRNA
- April 24, 2014
Science Daily/University of South Carolina
With a new generation of military veterans returning home from Iraq and Afghanistan, post-traumatic stress disorder (PTSD) has become a prominent concern in American medical institutions and the culture at-large. Estimates indicate that as many as 35 percent of personnel deployed to Iraq and Afghanistan suffer from PTSD. New research is shedding light on how PTSD is linked to other diseases in fundamental and surprising ways.
The rise in PTSD has implications beyond the impact of the psychiatric disorder and its immediate consequences, which include elevated suicide risk and inability to lead a normal life, that result in approximately $3 billion in lost productivity every year. Over time, these PTSD patients will continue to experience increased risks of a myriad of medical conditions like cardiovascular disease, diabetes, gastrointestinal disease, fibromyalgia, musculoskeletal disorders and others, all of which share chronic inflammation as a common underlying cause.
Dr. Mitzi Nagarkatti sums up the significance of this study as follows: "We are very excited about these results. Thus far, no one had looked at the role of microRNA in the blood of PTSD patients. Thus, our finding that the alterations in these small molecules are connected to higher inflammation seen in these patients is very interesting and helps establish the connection between war trauma and microRNA changes."
In addition to the alterations in microRNA expression, the study also found that PTSD patients had higher levels of inflammation caused by certain types of immune cells called T cells. These T cells produced higher levels of inflammatory mediators called cytokines, specifically interferon-gamma and interleukin-17. This finding was especially interesting because one of the inflammation-associated microRNAs, miR-125a, which specifically targets increased production of interferon-gamma, was found to have decreased expression in the PTSD patients studied. Overall, these results suggested that trauma may cause alterations in the expression of microRNA which promote inflammation in PTSD patients.
Commenting on this, Dr. Prakash Nagarkatti said, "These studies form the foundation to further analyze the role of microRNA in PTSD. Trauma experienced during war may trigger changes in microRNA which may in turn cause various clinical disorders seen in PTSD patients. Our long-term goal is to identify whether PTSD patients express a unique signature profile of microRNA which can be used towards early detection, prevention and treatment of PTSD."
