AI Article Synopsis
- Stress is a common cause of short-term insomnia and is linked to reduced slow wave sleep (SWS), although this has not been extensively studied through polysomnography.
- The study investigated how anxiety about the upcoming workday affects sleep quality and sleep patterns, using data from 37 participants.
- Results showed that fear of a challenging day correlates with less SWS, more time in stage 2 sleep, increased anxiety at bedtime, and poorer subjective sleep quality, suggesting that even moderate daily stress can impair restorative sleep.
Article Abstract
Stress is probably the most frequent cause of short-term insomnia, although it has seldom been documented polysomnographically. A few studies have shown that apprehension is associated with a reduction of slow wave sleep (SWS). The aim of the present study was to examine whether apprehension of the next working day would be related to sleep polysomnography and subjective sleep quality. In this analysis we made use of two different studies (n = 37, mean age: 37 years) that provided inter-individual variation in apprehension of the subsequent working day. The results confirm previous findings that apprehension of a difficult next day is associated with decreased amount of SWS, increased percentage of stage 2 sleep, bedtime state anxiety and subjectively poor sleep. It is concluded that moderate "everyday" stress may disturb physiological restoration as indicated by the reduction of SWS.

Implementing Internet-Delivered Cognitive Behavioral Therapy for Depression and Anxiety in Adults: Systematic Review.
J Med Internet Res
January 2025
Trinity College Dublin, Dublin, Ireland.
Background: Scientific implementation findings relevant to the implementation of internet-delivered cognitive behavioral therapy (iCBT) for depression and anxiety in adults remain sparse and scattered across different sources of published information. Identifying evidence-based factors that influence the implementation of iCBT is key to successfully using iCBT in real-world clinical settings.
Objective: This systematic review evaluated the following: (1) aspects that research articles postulate as important for the implementation of iCBT and (2) aspects relevant to the day-to-day running of iCBT services.
CD40 Ligand and CD40: Expression, Regulation, and Function at the Maternal-Conceptus Interface in Pigs.
Reproduction
January 2025
H Ka, Biological Science and Technology, Yonsei University - Mirae Campus, Wonju, Korea (the Republic of).
To successfully establish and maintain pregnancy in pigs, a variety of factors must work together at the maternal-conceptus interface to form an immune environment appropriate for both the mother and the conceptus. Our transcriptomics study has shown that cluster of differentiation ligand 40 (CD40L) and its receptor CD40, which are known to play important roles in regulating cell- and antibody-mediated immunity, are expressed in the endometrium during early pregnancy. However, the roles of the CD40L and CD40 signaling system are not well understood.

Importance: Cannabis use has increased globally, but its effects on brain function are not fully known, highlighting the need to better determine recent and long-term brain activation outcomes of cannabis use.
Objective: To examine the association of lifetime history of heavy cannabis use and recent cannabis use with brain activation across a range of brain functions in a large sample of young adults in the US.
Design, Setting, And Participants: This cross-sectional study used data (2017 release) from the Human Connectome Project (collected between August 2012 and 2015).
Center-Based Childcare Access to Health Screenings and Developmental Assessments in U.S. Children from Birth to Five.

School of Public Health (Population Health Sciences), Mark Chaffin Ctr. for Healthy Development (Leadership in Disability), School of Public Health, Georgia State University, Atlanta, GA, USA.
Objective: To examine the odds of children aged 0-5 in center-based childcare programs receiving referrals for health screenings and developmental assessments, controlling for children's races/ethnicities and provider and program factors.
Methods: We conducted secondary analyses using the 2019 National Survey for Early Care and Education (NSECE) Center-based Provider survey. We used multivariate logistic regression models to estimate referral odds for health screenings and developmental assessments from centers without these services onsite.
Robotic Anatomical Segment VIII Resection for Hepatocellular Carcinoma Using the Scissor Hepatectomy Technique.
Ann Surg Oncol
January 2025
Department of General and Visceral Surgery, Ulm University Hospital, Ulm, Germany.
Background: Robotic hepatectomy has been increasingly adopted for the treatment of hepatocellular carcinoma (HCC). However, the ideal technique of parenchymal transection in robotic hepatectomy has been a matter of ongoing debate in literature.
Patients And Methods: In this video, we demonstrate the technique of robotic anatomical segment VIII resection using the scissor hepatectomy technique for parenchymal transection on a 75-year-old male patient with a solitary HCC lesion.
