RESUMO
Purpose: To investigate the frequency of sleep disturbance and its effects on quality of life in adults with untreated primary brain tumors. Methods: This cross-sectional study recruited 68 and 35 patients with newly diagnosed benign and malignant brain tumors, respectively. All participants completed the Chinese versions of the Athens Insomnia Scale, Epworth Sleepiness Scale, Pittsburgh Sleep Quality Index, Hospital Anxiety and Depression Scale, Brief Fatigue Inventory, and EORTC-QLQ-BN20 for quality-of-life assessment. An actigraph was used to measure sleep parameters [e.g., dichotomy index (I < O)], for at least 3 consecutive days in untreated status. Results: The majority of the patients with benign and malignant tumors had meningioma (57.4%) and glioblastoma (40%), respectively. The prevalence of insomnia, poor sleep quality, and excessive daytime sleepiness was 59.2%, 77.7%, and 4.9%, respectively. The prevalence rates of sleep disturbances were not affected by tumor locations (suprasellar vs. non-suprasellar tumors) and tumor types (benign vs. malignant tumors). Only 36 participants completed actigraphy assessments (I < O = 95.4) due to having a tight schedule, actigraph malfunction, or not having the habit of wearing a wristwatch; 61% of them experienced circadian rhythm disruption (I < O ≤ 97.5). Insomnia was the only sleep parameter that significantly affected quality of life after controlling for potential confounders (B = 0.54, p = 0.03, adjusted R2 = 0.60). Conclusion: More than 60% of the patients with primary malignant and benign brain tumors experienced insomnia, poor sleep quality, and circadian rhythm disruption. Insomnia was independently correlated with quality of life in untreated status. Health-care providers can apply these findings to design effective interventions targeting sleep disturbance to improve quality of life in this population.

RESUMO
PURPOSE: To explore the prevalence of sleep disturbances and their effects on quality of life in adults with pituitary tumor or meningioma. METHODS: This prospective study included 33 and 44 patients with pituitary tumor and meningioma, respectively. All participants completed a series of valid questionnaires for assessing sleep and quality of life; all participants wore 3-day actigraph prior to related treatment. The actigraph-derived sleep parameters included total sleep time, sleep onset latency, wake after sleep onset, sleep efficiency, and dichotomy index (I < O) value. RESULTS: The prevalence of insomnia, excessive daytime sleepiness, and poor sleep quality was 46.8%, 6.5%, and 81.8%, respectively. The differences in these sleep parameters between patients with pituitary tumor and those with meningioma were nonsignificant. Only 27 participants completed the actigraphic assessments. The mean I < O value was 95.99%, and nearly 60% participants exhibited circadian rhythm disruption. Sleep quality was the only sleep variable independently correlated with preoperative quality of life, even after adjustments for confounders (B = 0.80, p = 0.02). CONCLUSIONS: Insomnia, poor sleep quality, and disrupted circadian rhythm are highly prevalent in adults with untreated pituitary tumor or meningioma. Sleep quality independently correlated with quality of life. We indirectly confirmed that tumor location may not be a possible cause of sleep changes.

Two new 12-hydroxybriarane diterpenoids, designated as excavatoids O (1) and P (2), were isolated from the octocoral Briareum excavatum. The structures of briaranes 1 and 2 were established on the basis of extensive spectral data analysis. Excavatoid P (2) is the first metabolite which possesses a 6ß -chlorine atom in briarane analogues.

A new bioactive sterol glycoside, 3beta-O-(3',4'-di-O-acetyl-beta-D-arabinopyranosyl)-25xi-cholestane-3beta,5alpha,6beta,26-tetrol-26-acetate) (carijoside A, 1), was isolated from an octocoral identified as Carijoa sp. The structure of glycoside 1 was established by spectroscopic methods and by comparison with spectral data for the other known glycosides. Carijoside A (1) displayed significant inhibitory effects on superoxide anion generation and elastase release by human neutrophils and this compound exhibited moderate cytotoxicity toward DLD-1, P388D1, HL-60, and CCRF-CEM tumor cells.

Three new 12-hydroxybriarane diterpenoids, excavatoids L-N (1-3), have been isolated from the cultured octocoral Briareum excavatum. The structures of new briaranes 1-3 were elucidated by the interpretations of spectroscopic methods. Excavatoid L (1) displayed moderate inhibitory effects on superoxide anion generation and elastase release by human neutrophils.
