Fruits, vegetables, and micronutrients in relation to breast cancer modified by menopause and hormone receptor status.

Whether fruit, vegetable, and antioxidant micronutrient consumption is associated with a reduction in breast cancer incidence remains unresolved. To address this issue, we analyzed data from a large population-based case-control study, with consideration given to whether the associations varied with menopausal status or with clinical characteristics of the cases' disease. Study participants completed a modified Block food frequency questionnaire, which included assessment of the frequency and portion sizes of 13 fruits and fruit juices and 16 vegetables and the use of multiple and single vitamin supplements. Statistical analyses were done on 1,463 cases and 1,500 controls. Among postmenopausal women, reduced odds ratios [OR; 95% confidence intervals (95% CI)] were noted for the highest fifth, as compared with the lowest fifth, of intake of any vegetables [0.63 (0.46-0.86); P for trend < 0.01] and leafy vegetables [0.66 (0.50-0.86); P for trend = 0.03] after controlling for age and energy intake. Adjusted ORs (95% CIs) were also decreased for postmenopausal breast cancer in relation to high intake of carotenoids, alpha-carotene, beta-carotene, lutein, and particularly lycopene [0.66 (0.48-0.90); P for trend = 0.03]. Inverse associations for fruits and vegetables were stronger for postmenopausal women with estrogen receptor (ER)+ tumors (OR, 0.65; 95% CI, 0.51-0.82) than ER- tumors (OR, 0.92; 95% CI, 0.64-1.32), but results were less consistent for micronutrients. No similarly reduced associations were observed among premenopausal women. ORs did not appreciably differ by in situ or invasive breast cancer or by whether cases had begun chemotherapy. Our results support an inverse association for fruit and vegetable intake among postmenopausal but not premenopausal breast cancer, which may be more pronounced among women with ER+ tumors.     

Reliability of the Dominic-R: A Young Child Mental Health Questionnaire Combining Visual and Auditory Stimuli

Reliability of the Dominic-R, a. questionnaire combining visual and auditory stimuli, was tested in 340 community children aged 6 to 11 years. Test-retest reliability of symptoms of, and of symptom scores of, DSM-III-R disorders including simple phobias, separation anxiety disorder, overanxious disorder, depression/dysthymia, attention deficit/ hyperactivity disorder, oppositional defiant disorder, and conduct disorder was assessed. Most symptoms yielded kappas greater than .40, and ICCs ranged from .74 to .81. In conclusion, reliability of the Dominic-R compares favourably with that of other child assessment questionnaires.     

Enhancement of survival of stored dopaminergic cells and promotion of graft survival by exposure of human fetal nigral tissue to glial cell line--derived neurotrophic factor in patients with Parkinson's disease. Report of two cases and technical considerations

The authors have studied the ability of glial cell line-derived neurotrophic factor (GDNF) to promote survival of human fetal dopaminergic tissue after a storage period of 6 days and subsequent implantation into the human putamen. The results indicate that GDNF promotes survival of stored dopaminergic cells. Cells stored without GDNF had a 30.1% decrease in survival time compared with those exposed to GDNF. Two patients with Parkinson's disease received bilateral putaminal implants of fetal dopaminergic cells exposed to GDNF for 6 days and showed enhancement of graft survival as assessed by positron emission tomography scanning. A mean increase of 107% in putaminal fluorodopa uptake from baseline values was observed 12 months postgrafting.     

Temporomandibular Disorder Treatment Outcomes: Second Report of a Large-Scale Prospective Clinical Study

Longitudinal studies of outcomes for temporomandibular disorder (TMD) treatment are rarely done and even when conducted often suffer methodological weaknesses. These may include the lack of valid outcome measures for symptom changes. This second report of a long-term multi-site study of 2104 treated, 250 untreated, and 44 long-term treated TMD patients is part of a continuing effort to study TMD treatment efficacy in a very large patient population. A validated symptom measurement system, the TMJ Scale, assured a valid and uniform assessment of treatment outcomes across a large number of practices. Data indicate that untreated TMD patients do not improve spontaneously over time and that patients treated with a variety of active modalities achieve clinically and statistically significant levels of improvement with no evidence of symptom relapse after treatment completion. The use of anterior repositioning appliance therapy produced better results than flat plane splint therapy.
