The trial lasted6 wk with flexible dosing of light starting with 10000 lux bright light for 60 min daily in the morning. At the end of six weeks there were 65 completers. Three patients had Bipolar Ⅱ disorder and the remainder had Major depressive disorder. Outcome measures were remission(score ≤ 8) and response(50% reduction)in symptoms on the Structured Interview Guide for the Hamilton Rating Scale for Depression(SIGH-SAD)as well as symptomatic improvement on SIGH-SAD and Beck Depression Inventory-Ⅱ. Adherence was measured using participant daily log. Participant groups were compared using t-tests, chi square, linear and logistic regressions. RESULTS: The study did not find any significant group difference between African-Americans and their Caucasian counterparts in adherence with light treatment as well as in symptomatic improvement.While symptomatic improvement and rate of treatment response were not different between the two groups,African-Americans, after adjustment for age, gender and adherence, achieved a significantly lower remission rate(African-Americans 46.3%; Caucasians 75%; P =0.02).CONCLUSION: This is the first study of light treatment in African-Americans, continuing our previous work reporting a similar frequency but a lower awareness of SAD and its treatment in African-Americans. Similar rates of adherence, symptomatic improvement and treatment response suggest that light treatment is a feasible, acceptable, and beneficial treatment for SAD in African-American patients. These results should lead to intensifying education initiatives to increase awareness of SAD and its treatment in African-American communities to increased SAD treatment engagement.In African-American vs Caucasian SAD patients a remission gap was identified, as reported before with antidepressant medications for non-seasonal depression, demanding sustained efforts to investigate and then address its causes.展开更多

The surface morphology of wafers and the current voltage characteristics of fabricated light emitting diode devices are investigated. It is shown that surface treatment with boiled aqua regia could effectively remove oxide from the surface of the p-GaN layer, and reveal defect-pits whose density is almost the same as the screw dislocation density estimated by x-ray rocking curve measurement. It suggests that the metal atoms of the Ni/Au transparent electrode of light emitting diode devices may diffuse into the p-GaN layer along threading dislocation lines and form additional leakage current channels. Therefore, the surface treatment time with boiled aqua regia should not be too long so as to avoid the increase of threading dislocation-induced leakage current and the degradation of electrical properties of light emitting diodes.展开更多

The underlying factors for the disorder are physiological changes of the sleep-wake cycle, comorbid diseases and drug treatment. Cognitive behavioural therapy (CBT I) combined with light therapy and physical activity can be effective in the treatment of comorbid insomnia in older adults. Methods: Sixty-three (63) insomnia patients (47 female, 16 male) with an average age of 66.6 years participated in the program. Before and after the treatment, the participants completed questionnaires to assess their sleep quality (PSQI), day-time sleepiness (ESS), mood (BDI) and well-being (WHO-5-Index). In addition, they kept sleep diaries for six weeks. Results: Pre-post comparisons revealed a significant improvement in sleep latency and sleep quality, as well as a significant reduction of day-time sleepiness. In patients with both insomnia and depression, all depression scores improved slightly but significantly. Conclusions: Non-pharmacological combination treatment using CBT I, light therapy and physical activity seemed to be effective in older adults with comorbid insomnia and improve additionaly depressive symptoms.展开更多
