Abstract Introduction Patients with craniopharyngioma are at increased risk for hypersomnia/narcolepsy and circadian rhythm disruption, secondary to hypothalamic-pituitary involvement of the tumor. We assessed youth with craniopharyngioma to determine presence of the dim light melatonin onset (DLMO) and concurrent sleep disturbance. Methods Fifty-two patients (7-21 years; 51% female) enrolled on our institutional protocol for craniopharyngioma that included surgery, proton therapy, or both. In-home salivary melatonin was collected after surgery and hourly beginning 3 h before to 1 h after habitual bedtime to determine the DLMO, which was defined as the time that melatonin exceeded a 4 pg/mL threshold. Polysomnography and a next day multiple sleep latency test (MSLT) were also conducted. Results Hypersomnia/narcolepsy was indicated in 86% of patients. DLMO was detected in 29 (56%) patients and averaged 21:04 (±1:14). All but 2 patients with a DLMO had a concurrent sleep diagnosis (18 hypersomnia, 8 narcolepsy, 1 insomnia). In those we could not compute a DLMO, melatonin was above the 4 pg/mL threshold in 19 (37%), suggesting that the DLMO was likely earlier than the sampling window. Two (4%) did not reach threshold, suggesting that the DLMO was later than the window. For patients in which DLMO was not computed, all but 4 had a concurrent sleep diagnosis (7 hypersomnia, 9 narcolepsy, 1 MSLT not completed). Three (6%) participants showed a pattern of melatonin decreasing before bedtime (2 hypersomnia, 1 narcolepsy). Sleep disorder diagnosis was not associated with whether a DLMO was detected or not. Conclusion DLMO did not occur within the sampling window in 44% of patients with the majority due to the DLMO likely occurring before sampling started. Simultaneous assessment of both sleep-wake disturbance and circadian phase could provide more informed sleep interventions for excessive sleepiness and circadian misalignment in this patient population. Support This study was supported by cancer center grant (CA21765) from the National Cancer Institute, and ALSAC.

Abstract Background There is increasing evidence that bipolar disorder is influenced by circadian timing, including the timing of sleep and waking activities. Previous studies in bipolar disorder have shown that people with later timed daily activities, also known as late chronotypes, are at higher risk for subsequent mood episodes over the following 12–18 months. However, these studies were limited to euthymic patients and smaller sample sizes. The aim of the current study was to further examine baseline chronotype as a potentially important predictor of mood-related outcomes in a larger sample of individuals with bipolar disorder and over the longest follow up period to date, of 5 years. Participants included 318 adults diagnosed with bipolar I and II (19–86 years) who were enrolled in the Prechter Longitudinal Study of Bipolar Disorder. Results Participants with a late chronotype were found to be more likely to have mild to more severe depressive symptoms (PHQ-9 ≥ 5) as captured with PHQ-9 assessments every 2 months over the 5 year follow up period. This higher risk for depressive symptoms remained even after adjusting for age, sex and mood at baseline. Additionally, late chronotypes reported fewer hypomania/mania episodes during the 5 year follow up, as derived from clinical interviews every two years. Conclusions These results highlight the potential clinical usefulness of a single self-report question, in identifying patients at risk for a more depressive mood course. The results also suggest that circadian phase advancing treatments, that can shift circadian timing earlier, should be explored as a means to reduce depressive symptoms in late chronotypes with bipolar disorder.

Abstract. Objective: In recent years, bright light therapy (BLT) has been used to treat depression and to stabilize circadian rhythms. In this study we evaluated whether it is also helpful for comorbid symptoms of affective and behavioral dysregulation in depressive inpatients. Method: This article reports a secondary analysis comparing two subgroups of depressive participants with comorbid affective and behavioral dysregulation, captured with the dysregulation-profile of the Strengths and Difficulties Questionnaire (SDQ-DP; n = 16 vs. n = 11). Participants were randomly allocated to active BLT (10,000 lux) or control BLT (approx. 100 lux), and received 45 minutes of BLT for 2 weeks. SDQ-DP scores, sleep parameters, and circadian preference were assessed at baseline, after the intervention, and 3 weeks later. Results: No direct effects on SDQ-DP scores were observed. Sleep improved in both conditions. Only in the active BLT condition was a circadian phase advance found. Correlation and regression analyses indicated an indirect, circadian effect for improved SDQ-DP scores. Conclusions: The data of this pilot trial should be considered preliminary and merely descriptive. Further research is warranted.

Pemberian Air Susu Ibu (ASI) masih merupakan masalah bagi pemenuhan kebutuhan nutrisi bayi baru lahir. Dukungan agar ibu menyusui bayi merupakan hal penting dalam menginisiasi dan mempertahankan pemberian ASI. Strategi dibutuhkan untuk mendukung keberhasilan menyusui. Tujuan penelitian adalah menganalisis efektivitas comprehensive breastfeeding education terhadap keberhasilan pemberian (ASI) pada periode postpartum. Jenis penelitian ini menggunakan kuasi eksperimen one group pre post test repeated measured design. Jumlah sampel sebanyak 22 ibu dengan menggunakan teknik accidental sampling. Pengumpulan data dilaksanakan pada bulan September–Oktober 2013 di Puskesmas wilayah Kota Tangerang Selatan. Intervensi dilakukan selama 30 menit. Pengumpulan data dilakukan sebelum intervensi, 3 hari setelah intervensi (post1), dan 10 hari setelah intervensi (post 2). Pengumpulan data menggunakan kuesioner dan observasi. Keberhasilan pemberian ASI berdasar pada parameter pengetahuan, langkah menyusui, perlekatan bayi, dan kecukupan ASI. Analisis data menggunakan general linear model repeated measureANOVA. Hasil penelitian menunjukkan adanya signifikansi comprehensive breastfeeding education (p=0.001). Rata-rata keberhasilan pemberian ASI sebelum dan setelah intervensi meningkat. Sebesar 93,9% intervensi memengaruhi tingkat keberhasilan. Rata-rata sebelum intervensi 56,74 (SD 5,92), post 1 sebesar 60,83 (SD 6,38) dan post2 sebesar 74,55 (SD 5,32). Subvariabel yang memiliki efek secara signifikan setelah intervensi adalah pengetahuan (p=0.001) dan langkah menyusui (p=0.001), sedangkan subvariabel perlekatan bayi (p=0.061) dan kecukupan ASI (p=0.162) tidak secara signifikan berbeda antara sebelum dan setelah intervensi. Pelaksanaanbreastfeeding education disarankan pada ibu agar dapat melakukan posisi perlekatan bayi yang benar sehingga dapat mengurangi masalah-masalah berkaitan dengan perlekatan yang tidak sesuai seperti puting perih, lecet atau berdarah, dan bayi kurang puas dalam menyusu yang bisa mengakibatkan gagalnya program ASI ekslusif.Kata kunci:Menyusui, pendidikan, perlekatan, postpartum AbstractBreastfeeding have still been problem for adequate newborn nutrition. Adequate breastfeeding support is essential for mothers to initiate and maintain optimal breastfeeding practices. A strategic needed to support successful breastfeeding. The purpose of research is to analyze the effectiveness comprehensive breastfeeding education on successful breastfeeding at postpartum periods. A quasi-experimental one group pretest, post test, repeated mesaured was used. This study was conducted at public health in Tangerang Selatan municipality in September–October 2013 among 22 postpartum mothers, convenience sampling methods. Intervention was done 30 minute. Data were collected before intervention (pretest), third day after intervention (post 1) and tenth day after intervention (repeated/post 2) using four parameter, that are knowledge, breastfeeding steps, proper lacth-on and adequate breastmilk. Using repeated measures analysis of variance there was a significant increase (p=0.001) in the overall Successful breastfeeding mean. Around 93,9% the effectiveness of intervention influence on successful. The mean before intervention is 56,74 (SD 5,92), increased at post 1:60,83 (SD 6,38) and post 2:74,55 (SD 5,32). Subvariable which has effect significantly after intervention is knowledge (p=0.001) and breastfeeding steps (p=0.001), in contrary, proper latch-on (p=0,061) and adequate breastmilk (p=0.162) have no significant effect after intervention. Suggestion to support breastfeeding education and counselling proper latch-on adequately that can decrease the problem such as painful, creaks or bloody putting.Key words: Breastfeeding, education, latch-on, postpartum
