Background: Oxytocin can stimulate release of myocardial biomarkers troponin I and T, prolong QTc and induce ST-depression.
Objective: To explore cardiac changes after either intravenous carbetocin or oxytocin.
Study Design: Exploratory phase 4 randomised controlled trial.
Setting: Obstetrics units of Oslo University Hospital, Norway between September 2015 and May 2018.
Participants: Forty healthy, singleton pregnant women aged 18 to 50 years at gestational age at least 36 weeks with a planned caesarean delivery.
Interventions: Participants were randomised to receive either oxytocin 2.5 IU or carbetocin 100 μg immediately after delivery.
Main Outcome Measures: The primary endpoint was the assessment of troponin I within 48 h of study drug administration. Troponin I and T, and creatine kinase myocardial band assessments were measured before spinal anaesthesia (baseline), and again at 4, 10 and 24 h after delivery. QTc, ST-depression and relative increase in heart rate were recorded from start of study drug administration to 10 min after delivery. All adverse events were monitored.
Results: Compared with the carbetocin group, higher troponin I levels were observed in the oxytocin group at 4 h and 10 h after delivery. For both treatment groups, an increase from baseline in troponin I and T was most pronounced at 10 h after delivery, and it had begun to decline by 24 h. QTc increased with time after administration of both study drugs, with a mean maximum increase of 10.4 ms observed at 9 min (P < 0.001). No statistical differences were observed in QTc ( P = 0.13) or ST-depression ( P = 0.11) between the treatment groups.
Conclusions: Oxytocin 2.5 IU and carbetocin 100 μg caused a similar increase in QTc. The trial was underpowered with regards to ST-depression and the release of myocardial biomarkers and these warrant further investigation. Data from this trial will inform a larger phase 4 trial to determine potential drug differences in troponin release.

Background: Existing epigenome-wide association study (EWAS) investigating the association between DNA methylation (DNAm) and child neurodevelopment have been predominantly conducted within Western populations, and yielded inconsistent results, leading to a significant gap within non-Western setting, particularly in resource-limited rural areas of Central China.
Objectives: To investigate the association between altered epigenome-wide DNAm and neurodevelopment in preschool children from resource-limited rural areas of Central China.
Methods: This case-control study involved 64 preschoolers.

Preterm birth (PTB) remains a leading cause of neonatal morbidity and mortality, with inflammation-induced PTB posing a significant challenge due to its complex pathophysiology. To address this, we developed an in vitro platform utilizing hTERT-immortalized human myometrial (hTERT-HM) cells integrated with a multielectrode array (MEA) biosensing system and optical calcium imaging. Compared to primary uterine myometrial cells, hTERT-HM cells exhibit superior reproducibility, high scalability, and convenient manipulation, facilitating the consistent and large-scale investigations.

Social cognition, which ranges from recognizing social cues to intricate inferential reasoning, is influenced by environmental factors and epigenetic mechanisms. Notably, methylation variations in stress-related genes like brain-derived neurotrophic factor (BDNF) and the oxytocin receptor (OXTR) are linked to distinct social cognitive functions and exhibit sex-specific differences. This study investigates how these methylation differences affect social cognition across sexes, focusing on both perceptual and inferential cognitive levels.

Recent studies indicate that central administration of oxytocin (OT) reduces body weight (BW) in high fat diet-induced obese (DIO) rodents by reducing energy intake and increasing energy expenditure (EE). Previous studies in our lab have shown that administration of OT into the fourth ventricle (4V; hindbrain) elicits weight loss and stimulates interscapular brown adipose tissue temperature (T) in DIO rats. We hypothesized that OT-elicited stimulation of sympathetic nervous system (SNS) activation of IBAT contributes to its ability to activate BAT and reduce BW in DIO rats.

Refractory cancer pain affects 10-20% of patients with advanced malignancies and is not adequately controlled by opioids. The intrathecal therapy is an effective interventional procedure for referral, but the implanted infusion pumps are costly and the refilling requires technical expertise. Hypophysectomy, in its three stages-surgical, chemical, and radiosurgical-has emerged as an alternative for managing this pain.
