A Restorative Yoga Intervention for African-American Breast Cancer Survivors: a Pilot Study.

BACKGROUND: Data show that yoga is effective for improving health-related outcomes in breast cancer survivors. While breast cancer is the most commonly diagnosed cancer among African-American women (AAW), AAW are less likely to engage in yoga compared to other ethnic groups. The goals of the current study were to assess the feasibility of an 8-week restorative yoga program among African-American breast cancer survivors (AA BCS). Specifically, study aims were to (1) measure changes in study outcomes in a restorative yoga (RY) group compared to a wait list control group, (2) assess adherence to the RY program, and (3) assess program satisfaction among study participants. METHODS: Thirty-three AA BCS were randomly assigned to either the RY intervention (n = 18) or wait list control group (n = 15). RY classes met once per week for 8 weeks. Pre- and post-testing assessments were measured at 0 and 8 weeks (immediately post-intervention). RESULTS: Depression scores at follow-up were significantly lower in the yoga group (M = 4.78, SD = 3.56) compared to the control group (M = 6.91, SD = 5.86). No significant group differences were observed for sleep quality, fatigue, or perceived stress. Yoga program participants completing baseline assessments demonstrated 61% adherence to the yoga classes. Average rating of the yoga program was "very useful." Recommendations for future yoga programs were provided. CONCLUSIONS: This study suggests that yoga has a beneficial effect on depression in AA BCS. There is, however, a need to further explore the benefits of yoga among minority breast cancer survivors using a study with larger sample sizes.

Synthesis and anticonvulsant activity of enaminones. Part 7. Synthesis and anticonvulsant evaluation of ethyl 4-[(substituted phenyl)amino]-6-methyl-2-oxocyclohex-3-ene-1-carboxylates and their corresponding 5-methylcyclohex-2-enone derivatives.

Further investigation of the potential anticonvulsant activity of the enaminones was attempted to discern the possible role of metabolites as the active/co-active entities of the esters of the enaminones. A series of 5-methyl-2-cyclohexene enaminones, the hypothesised metabolites corresponding to a sequence of active and inactive esters were synthesised and evaluated for anticonvulsant activity. With two exceptions, ethyl 4-[(4-cyanophenyl)amino]-6-methyl-2-oxocyclohex-3-ene-1-carboxylate (1k), and 3-[N-(4-cyanophenyl)amino]-5-methyl-2-cyclohexenone (3g), and ethyl 4-(phenylamino)-6-methyl-2-cyclohexenone (1n), and 3-N-(phenylamino)-5-methyl-2-cyclohexenone (3j), anticonvulsant screening data were parallel, with the ester and their putative decarboxylated analogue displaying similar activity. The most active analogue evaluated in this series, ethyl 4-[(4-chlorophenyl)amino]-6-methyl-2-oxocyclohex-3-ene-1-carboxylate (1e), which displayed an ED(50) of 16.7 mg kg(-1) and a TD(50) of 110.7 mg kg(-1) (protective index, PI = TD(50)/ED(50) = 6.6) in the maximal electroshock seizure (MES) test in mice and an ED(50) of 3.0 mg kg(-1) and a TD(50) >250 mg kg(-1) (PI > 83.3) in rats in the same evaluation, making this compound the most potent enaminone emanating from our laboratories. Pharmacokinetic evaluation of compound 1e in rats using LC/MS analysis unequivocally provides evidence that this compound is converted into the decarboxylated analogue 3a in the brain and the urine.
