Anaplastic large cell lymphoma, ALK-positive is a mature T-cell neoplasm that accounts for 10- 20% of paediatric non-Hodgkin lymphoma. Its frequency in infants and very young children is exceedingly rare and was rarely documented in the literature. The disease prognosis in this agegroup is unknown. We report two male patients who were diagnosed with ALCL-ALK(+) at the ages of 12 and 14 months, both presented with fever and leukemoid reaction, one was in stage I and the other in stage IV diseases. They were treated with APO-based chemotherapy and remained in complete remission for more than 7 years. To our knowledge, this is the first report that describes the long-term survival of ALCL-ALK(+) at very young age.
Chrononutrition has been suggested to have an entrainment effect on circadian rhythm which is crucial for metabolic health. Investigating how chrononutrition affects maternal circadian rhythm can shed light on its role during pregnancy. This study aims to determine chrononutrition characteristics of healthy primigravida during pregnancy and its association with melatonin and cortisol rhythm across gestation. A total of 70 healthy primigravidas were recruited from ten randomly selected government maternal and child clinics in Kuala Lumpur, Malaysia. During the second and third trimesters, chrononutrition characteristics including meal timing, frequency, eating window, breakfast skipping, and late-night eating were determined using a 3-day food record. Pregnant women provided salivary samples at five time-points over a 24 h period for melatonin and cortisol assay. Consistently across the second and third trimesters, both melatonin and cortisol showed a rhythmic change over the day. Melatonin levels displayed an increment toward the night whilst cortisol levels declined over the day. Majority observed a shorter eating window (≤12 h) during the second and third trimesters (66 and 55%, respectively). Results showed 23 and 28% skipped breakfast whereas 45 and 37% ate within 2 h pre-bedtime. During the third trimester, a longer eating window was associated with lower melatonin mean (β = -0.40, p = 0.006), peak (β = -0.42, p = 0.006), and AUCG (β = -0.44, p = 0.003). During both trimesters, a lower awakening cortisol level was observed in pregnant women who skipped breakfast (β = -0.33, p = 0.029; β = -0.29, p = 0.044). Only during the second trimester, breakfast-skipping was significantly associated with a greater cortisol amplitude (β = 0.43, p = 0.003). Findings suggest that certain chrononutrition components, particularly eating window and breakfast skipping have a significant influence on maternal melatonin and cortisol rhythm. Dietary intervention targeting these characteristics may be useful in maintaining maternal circadian rhythm.
Psychological distress during pregnancy may increase the risk of adverse maternal and infant outcomes. Past studies have demonstrated the association between circadian disturbances with psychological health. However, the roles of chronotype and social jetlag on psychological state during pregnancy are yet to be identified. We aimed to examine the psychological state in pregnant women and its relations to chronotype, social jetlag (SJL), sleep quality and cortisol rhythm. The current study included a subsample of participants from an ongoing cohort study. A total of 179 primigravidas (mean age 28.4 ± 4.0 years) were recruited. Chronotype and sleep quality during the second trimester were assessed using the Morning-Eveningness Questionnaire (MEQ) and Pittsburgh Sleep Quality Index (PSQI), respectively. SJL was calculated based on the difference between mid-sleep on workdays and free days. Psychological state of participants was evaluated using the Depression, Anxiety, and Stress Scale-21 (DASS-21). Subsamples (n = 70) provided salivary samples at 5 time points over a 24 h period during the second trimester for cortisol assay. A higher proportion of pregnant women experienced moderate to severe anxiety symptoms (n = 77, 43.0%), followed by depressive (n = 17, 9.5%) and stress (n = 14, 7.8%) symptoms. No association was observed between chronotype and psychological distress during pregnancy. There was no significant difference in cortisol rhythms in relation to psychological distress. SJL and sleep quality were significantly associated with stress symptoms among pregnant women in the second trimester. Poor sleep quality, particularly daytime dysfunction (β = 0.37, p = .006) and sleep disturbances (β = 0.23, p = .047), were significantly associated with psychological distress (depressive, anxiety and stress symptoms) during the second trimester. The findings suggest that sleep is a potential modifiable lifestyle factor that can be targeted to improve psychological health among pregnant women.
