(1) Background: Although the current literature shows that daylight saving time (DST) may play a role in human health and behavior, this topic has been poorly investigated with reference to Obstetrics. The aim of this case-control study was to evaluate whether DST may influence the number of spontaneous deliveries. (2) Methods: A low-risk pregnancy cohort with spontaneous onset of labor ( = 7415) was analyzed from a single Italian region for the period 2016-2018. Primary outcome was the number of spontaneous deliveries. Secondary outcomes were: gestational age at delivery, type and time of delivery, use of analgesia, birth weight, and 5-min Apgar at delivery. We compared the outcomes in the two weeks after DST (cases) to the two weeks before DST (controls). (3) Results: Data showed no significant difference between the number of deliveries occurring before and after DST (Chi-square = 0.546, = 0.46). Vaginal deliveries at any gestational age showed no statistical difference between the two groups (Chi-square = 0.120, = 0.73). There were no significant differences in the secondary outcomes, as well. (4) Conclusions: DST has neither a significant impact on the number of deliveries nor on the obstetric variables investigated by this study.

This study investigates the impact of twin intrahepatic cholestasis in pregnancy (ICP) in different chorionicity scenarios on pregnancy outcome and risk factors. This retrospective study was designed to investigate the association between ICP and pregnancy outcomes and associated risk factors. Logistic regression analysis was used to verify the correlation between ICP and pregnancy outcome and the associated risk factors with the risk of ICP.

This study investigated the relationship between maternal serum amyloid A (SAA) levels, a biomarker of systemic inflammation, and specific neonatal outcomes in preterm birth (PTB). The study included 66 consecutive pregnant women hospitalized for spontaneous preterm delivery (ranging from 28 to 36 gestational weeks), at the Timisoara Municipal Hospital. The study measured mSAA levels to assess their potential as predictors of fetal outcomes (respiratory distress syndrome [RDS]), as well as their association with APGAR score, neonatal leukocyte count, and C-reactive protein (CRP) levels as indicators of neonatal status and response.

Department of Obstetrics and Gynecology, Jean Minjoz Hospital, Besançon University Medical Center - Alexander Fleming Boulevard, 25000 Besançon, France; University of Franche-Comte-SINERGIE Laboratory, 25000 Besancon, France. Electronic address:

Objectives: The aim of this study was to analyse influence of the fetal head position and the type of instrument used (forceps, vacuum, OdonAssist™) on perineal deformation, during simulated vaginal deliveries monitored by stereophotogrammetry.

Methods: An exploratory study was conducted using mannequins simulating vaginal births. Fifty simulated deliveries were performed with different fetal head positions and instruments: Pajot's forceps, Kiwi-vacuum, and OdonAssist™.

Anaesthesia for paediatric radiotherapy: A narrative review.

Anaesthesia

The Christie NHS Foundation Trust, Manchester, UK.

Introduction: Radiotherapy is currently used in approximately one-third of children with cancer. Treatments are typically received as weekday outpatient appointments over 3-6 weeks. The treatment is painless but requires a still, co-operative patient who can lie alone in set positions, facilitated by the use of immobilisation devices, for up to 1 h.

Advancing Natural Killer Cell Therapy: Genetic Engineering Strategies for Enhanced Cancer Immunotherapy.

Ann Lab Med

January 2025

Department of Integrative Biotechnology, College of Biotechnology and Bioengineering, Sungkyunkwan University, Suwon, Korea.

Natural killer (NK) cells are pivotal innate immune system components that exhibit spontaneous cytolytic activity against abnormal cells, such as infected and tumor cells. NK cells have shown significant promise in adoptive cell therapy because of their favorable safety profiles and minimal toxicity in clinical settings. Despite their advantages, the therapeutic application of unmodified NK cells faces challenges, including limited in vivo persistence, particularly in the immunosuppressive tumor microenvironment.
