BACKGROUND:Patients irradiated for brain tumors often suffer from cerebral edema and are usually treated with dexamethasone, which has various side effects. To investigate the activity of Boswellia serrata (BS) in radiotherapy-related edema, we conducted a prospective, randomized, placebo-controlled, double-blind, pilot trial.

METHODS:Forty-four patients with primary or secondary malignant cerebral tumors were randomly assigned to radiotherapy plus either BS 4200 mg/day or placebo. The volume of cerebral edema in the T2-weighted magnetic resonance imaging (MRI) sequence was analyzed as a primary endpoint. Secondary endpoints were toxicity, cognitive function, quality of life, and the need for antiedematous (dexamethasone) medication. Blood samples were taken to analyze the serum concentration of boswellic acids (AKBA and KBA).

RESULTS:Compared with baseline and if measured immediately after the end of radiotherapy and BS/placebo treatment, a reduction of cerebral edema of>75% was found in 60% of patients receiving BS and in 26% of patients receiving placebo (P = .023). These findings may be based on an additional antitumor effect. There were no severe adverse events in either group. In the BS group, 6 patients reported minor gastrointestinal discomfort. BS did not have a significant impact on quality of life or cognitive function. The dexamethasone dose during radiotherapy in both groups was not statistically different. Boswellic acids could be detected in patients' serum.

CONCLUSIONS:BS significantly reduced cerebral edema measured by MRI in the study population. BS could potentially be steroid-sparing for patients receiving brain irradiation. Our findings will need to be further validated in larger studies.

BACKGROUND:Lifestyle modification (i.e., regular physical activity and diet) is effective in preventing the age-related increase in cardiovascular disease risks. Potential therapeutic effects of curcumin (diferuloylmethane) have been confirmed on various diseases, including cancer and Alzheimer's disease, but the effects of curcumin have not been tested on central arterial hemodynamics. The aim of this pilot study was to test the hypothesis that the regular endurance exercise combined with daily curcumin ingestion lowers the age-related increase in left ventricular (LV) afterload to a greater extent than monotherapy with either intervention alone in postmenopausal women using a randomized, double-blind, placebo-controlled, parallel manner.

METHODS:Forty-five women were randomly assigned to four interventions:"placebo ingestion"(n = 11),"curcumin ingestion"(n = 11),"exercise training with placebo ingestion"(n = 11), or"exercise training with curcumin ingestion"(n = 12). Curcumin or placebo pills (150 mg/day) were administered for 8 weeks. Aortic blood pressure (BP) and augmentation index (AIx), an index of LV afterload, were evaluated by pulse wave analysis from tonometrically measured radial arterial pressure waveforms.

RESULTS:There were no significant differences in baseline hemodynamic variables among four groups. After the interventions, brachial systolic BP (SBP) significantly decreased in both exercise-trained groups (P<0.05 for both), whereas aortic SBP significantly decreased only in the combined-treatment (e.g., exercise and curcumin) group (P<0.05). Heart rate (HR) corrected aortic AIx significantly decreases only in the combined-treatment group.

CONCLUSIONS:These findings suggest that regular endurance exercise combined with daily curcumin ingestion may reduce LV afterload to a greater extent than monotherapy with either intervention alone in postmenopausal women.

OBJECTIVE:To compare the acupuncture treatment and the medical treatment with antibiotics and nonsteroidal anti-inflammatory drugs (NSAIDs) on pain control, urinary symptoms, and quality of life of category IIIB chronic prostatitis-chronic pelvic pain syndrome (CP-CPPS).

METHODS:From November 2008 to May 2009, 54 male patients with category IIIB CP-CPPS were randomly divided into 2 groups: the medical treatment group (group 1, n = 28) and the acupuncture treatment group (group 2, n = 26). Group 1 took levofloxacin 500 mg daily and ibuprofen 200 mg twice a day for 6 weeks. In the acupuncture group (group 2), bilateral BL32 (Ciliao) and BL33 (Zhongliao) acupoints were used to stimulate the sacral nerve using an electrical pulse generator, twice a week for 7 weeks. The change in National Institutes of Health Chronic Prostatitis Symptom Index scores from the baseline to the end of the treatment was observed.

RESULTS:The mean follow-up was 28 weeks from the baseline (range, 20-43 weeks). In acupuncture group, reduction of pain, urinary symptoms, quality of life, and total National Institutes of Health Chronic Prostatitis Symptom Index score was higher compared with the medical group.

CONCLUSION:However the treatment of CP-CPPS is challenging and difficult for the urologists. This clinical study showed that the acupuncture treatment is a safe and effective treatment of category IIIB CP-CPPS.

Chronic migraine (CM) is a disabling condition arising from a complex mixture of interconnected biological, psychological and social factors, and is often associated with medication overuse (MO). Mindfulness is emerging as a helpful treatment for pain, and one study showed that the longitudinal 12 months' course of CM-MO patients that attended mindfulness-based treatment alone was similar to that of patients receiving medical prophylaxis alone; in this study, we describe the course of biomarkers of inflammation. Our results provide initial evidence of sustained similar effects on reduced concentration of biomarkers of inflammation, although not sizeable enough to reach statistical significance. Whether more intensive treatment and/or larger samples would lead to greater changes is unknown, but these encouraging preliminary findings suggest further research is warranted.

Ketogenic diet (KD) is a high-fat, low-protein and low-carbohydrate diet. It is reported that KD can provide the neuroprotection for the neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease (PD) and amyotrophic lateral sclerosis. The main clinical symptom of PD is motor dysfunction derived from the loss of dopaminergic neurons in the substantia nigra (SN) and dopamine content in the striatum subsequently. It is well known that treatments with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) in mice produce motor dysfunction, biochemical, and neurochemical changes remarkably similar to idiopathic PD patients. In this study, we investigated the neuroprotective and anti-inflammatory effects of KD in MPTP-treated mice. The data showed that pretreatment with KD alleviated the motor dysfunction induced by MPTP. The decrease of Nissl-staining and tyrosine hydroxylase (TH)-positive neurons induced by MPTP was inhibited in the SN. The change of dopamine was very similar to dopaminergic neurons in the SN. KD inhibited the activation of microglia induced by MPTP in the SN. The levels of proinflammatory cytokines (interleukin-1 beta, interleukin-6, and tumor necrosis factor-alpha) in the SN were also decreased and induced by MPTP. So, we concluded that KD was neuroprotective and anti-inflammatory against MPTP-neurotoxicity.

AIMS:To determine serum salicylic acid concentrations in non-vegetarians and vegetarians not taking salicylate drugs, and to compare these concentrations with those found in patients taking aspirin, 75 mg daily.

METHODS:Serum samples were obtained from vegetarians (n = 37) and non-vegetarians (n = 39) not taking salicylate drugs. Non-vegetarians and vegetarians were recruited from the community and from a Buddhist monastery, respectively, in Dumfries and Galloway, Scotland. Patients (n = 14) taking aspirin (75 mg daily) were recruited from the Dumfries diabetic clinic. Serum salicylic acid concentrations were determined using a high performance liquid chromatography method with electrochemical detection.

RESULTS:Salicylic acid was detected in every serum sample analysed. Higher serum concentrations of salicylic acid were found in vegetarians than non-vegetarians: median concentrations of 0.11 (range, 0.04-2.47) micromol/litre and 0.07 (range, 0.02-0.20) micromol/litre, respectively; the median of the difference was 0.05 micromol/litre (95% confidence interval for difference, 0.03 to 0.08; p<0.0001). The median serum concentration of salicylic acid in patients taking aspirin (75 mg daily) was 10.03 (range, 0.23-25.40) micromol/litre, which was significantly higher than that found in non-vegetarians and vegetarians. There was overlap in serum salicylic acid concentrations between the vegetarians and patients taking aspirin.

CONCLUSIONS:Salicylic acid, a non-steroidal anti-inflammatory drug, is present in fruits and vegetables and is found in higher concentrations in vegetarians than non-vegetarians. This suggests that a diet rich in fruits and vegetables contributes to the presence of salicylic acid in vivo. There is overlap between the serum concentrations of salicylic acid in vegetarians and patients taking aspirin, 75 mg daily. These findings may explain, in part, the health promoting effects of dietary fruits and vegetables.
