Sleep-related problems (SRPs) among adolescents are a growing concern. Theory and research suggest that emotional arousal may have cyclical relation with SRPs, but whether emotional dysregulation plays a role is not clear. We investigated associations between two physiological indices of emotion regulation (video baseline heart rate variability and change in heart rate variability to a stressor) and SRPs in a sample of 80 adolescents (ages 11-17 years; 51% female; 37.5% African American). The findings showed a negative relation between video baseline heart rate variability and SRPs, controlling for non-sleep-related anxiety disorder symptoms (β = -0.29) and general manifest anxiety (β = -0.25). We found no relation between change in heart rate variability to a stressor and SRPs when non-sleep-related anxious arousal was controlled. If replicated, findings illustrate the importance of physiological regulation of emotion influencing (or influenced by) SRPs during adolescence.

Circadian Misalignment Impacts Cardiac Autonomic Modulation in Adolescence.
Sleep
January 2025
Sleep Research & Treatment Center, Department of Psychiatry & Behavioral Health, Penn State University, College of Medicine, Hershey PA, USA.
Study Objectives: Although heart rate variability (HRV), a marker of cardiac autonomic modulation (CAM), is known to predict cardiovascular morbidity, the circadian timing of sleep (CTS) is also involved in autonomic modulation. We examined whether circadian misalignment is associated with blunted HRV in adolescents as a function of entrainment to school or on-breaks.
Methods: We evaluated 360 subjects from the Penn State Child Cohort (median 16y) who had at least 3-night at-home actigraphy (ACT), in-lab 9-h polysomnography (PSG) and 24-h Holter-monitoring heart rate variability (HRV) data.
Prediction of pre-eclampsia using maternal hemodynamic parameters at 12 + 0 to 15 + 6 weeks.

Department of Obstetrics and Gynaecology, Prince of Wales Hospital, The Chinese University of Hong Kong, Hong Kong, SAR, China.
Objectives: To compare the maternal hemodynamic profile at 12 + 0 to 15 + 6 weeks' gestation in women who subsequently developed pre-eclampsia (PE) and those who did not, and to assess the screening performance of maternal hemodynamic parameters for PE in combination with the Fetal Medicine Foundation (FMF) triple test, including maternal factors (MF), mean arterial pressure (MAP), uterine artery pulsatility index and placental growth factor.
Methods: This was a prospective case-control study involving Chinese women with a singleton pregnancy who underwent preterm PE screening at 11 + 0 to 13 + 6 weeks' gestation using the FMF triple test, between February 2020 and February 2023. Women identified as being at high risk (≥ 1:100) for preterm PE by the FMF triple test were matched 1:1 with women identified as low risk (< 1:100) for maternal age ± 3 years, maternal weight ± 5 kg and date of screening ± 14 days.

Heart failure is a complex clinical syndrome and pediatric heart failure (PHF) has a high mortality rate. Early diagnosis is crucial for treatment and management of PHF. In clinical practice, various tests and examinations play a key role in the diagnosis of PHF, including continuously updated biomarkers, echocardiography, and cardiac magnetic resonance imaging.

Department of Intensive Care Unit, The First Affiliated Hospital of Jinan University, Guangzhou, China.
Background: Despite the physiological advantages of positive end-expiratory pressure (PEEP), its optimal utilization during one-lung ventilation (OLV) remains uncertain. We aimed to investigate whether individualized PEEP titration by lung compliance is associated with a reduced risk of postoperative pulmonary complications during OLV.
Methods: We searched PubMed, Embase, and the Cochrane Central Register of Controlled Trials until April 1, 2024, to identify published randomized controlled trials that compared individualized PEEP titration by lung compliance with fixed PEEP during OLV.
Catheter-directed therapy for pulmonary embolism in pediatrics: a systematic review and meta-analysis.
Thromb J
January 2025
Pediatric Emergency Department, St. Christopher's Hopsoital for Children, Philadelphia, PA, USA.
Background: Acute pulmonary embolism (PE) is a serious and potentially fatal condition that is relatively rare in the pediatric population. In patients presenting with massive/submassive PE, catheter-directed Therapy (CDT) presents an emerging therapeutic modality by which PE can be managed.
Methods: Electronic databases were systematically searched through May 2024.
