Impact of high maternal body mass index on fetal cerebral cortical and cerebellar volumes.

Objectives: Maternal obesity increases a child's risk of neurodevelopmental impairment. However, little is known about the impact of maternal obesity on fetal brain development.

Methods: We prospectively recruited 20 healthy pregnant women across the range of pre-pregnancy or first-trimester body mass index (BMI) and performed fetal brain magnetic resonance imaging (MRI) of their healthy singleton fetuses.

A tackler correctly adhering to the tackle instruction in a front-on, one-on-one torso tackle alters the peak inertial head kinematics of the ball carrier but not the tackler.

Objectives: To evaluate if the tackler correctly adhering, or not, to four different instructions of legal front-on one-on-one torso tackles altered the tackler and/or ball carrier peak inertial head kinematics.

Design: Controlled laboratory study.

Methods: Fifteen rugby-code players measured with three-dimensional optoelectronic motion capture performed two tackle instructions from the Australian National Rugby League coaching manual on under (Dominant National Rugby League) and over (Smother National Rugby League) the ball tackles, and two novel variants of these (under, Dominant, Torso Stick; over, Smother, Pop, Lock).

Commonly Used Dose of Montmorency Tart Cherry Powder Does Not Improve Sleep or Inflammation Outcomes in Individuals with Overweight or Obesity.

Background/objectives: Sleep problems are frequently experienced and play an important role in inflammation and disease risk. US Montmorency tart cherries (MTC) improve sleep outcomes in previous studies, but studies in individuals with overweight and obesity are lacking.

Methods: A total of 34 individuals with sleep issues and overweight or obesity (BMI: 32.

Ultrasound-guided regional anesthesia (UGRA) in the emergency department: a scoping review.

Introduction: While many studies have been published on Ultrasound-guided regional anesthesia in the Emergency Department (ED), there has been no previous study assessing the current state of the literature based in the form of a scoping review.

Objective: The purpose of this study is to evaluate the current state of the literature on UGRA performed in the ED setting.

Methods: EMBASE, MEDLINE, CINAHL, and Cochrane databases were searched for studies.

Lead Level ≥5 µg/dL and Neurodevelopmental Outcomes of Preterm Infants at Five Years of Age.

Introduction: Prior studies have not examined blood lead levels (BLL) in the preterm population relative to their developmental and behavioral outcomes.

Methods: Neonatal demographic and clinical characteristics and results on scales of intelligence, development, and behavior were compared between children born ≤32 weeks gestation (n=354) with detected lead levels in childhood of ≥5 µg/dL (n=37, 10%) and <5 µg/dL (n=317, 90%).

Results: The 10% rate of BLL ≥5 µg/dL for this cohort was higher than rates previously reported for the general population, and was associated with low SES.

A scoping review of self-help cognitive behavioural therapy for insomnia.

Uptake of cognitive behavioural therapy for insomnia (CBTI) as first-line therapy of chronic insomnia has been restricted by a shortage of trained therapists, access barriers, and limited awareness of self-help alternatives. Self-help CBTI has emerged as a practical alternative, offering ready access, convenience, and dissemination and scalability efficiency. Yet, evidence syntheses of limited data have suggested its effectiveness and acceptability may be inferior to face-to-face CBTI and others have questioned its fidelity with CBTI standards.

Head Kinematics Associated with Off-Field Head Injury Assessment (HIA1) Events in a Season of English Elite-Level Club Men's and Women's Rugby Union Matches.

Objectives: The purpose of this study was to investigate head kinematic variables in elite men's and women's rugby union and their ability to predict player removal for an off-field (HIA1) head injury assessment.

Methods: Instrumented mouthguard (iMG) data were collected for 250 men and 132 women from 1865 and 807 player-matches, respectively, and synchronised to video-coded match footage. Head peak resultant linear acceleration (PLA), peak resultant angular acceleration (PAA) and peak change in angular velocity (dPAV) were extracted from each head acceleration event (HAE).

Disclosing Sexual Dysfunction in Newly Established Romantic Relationships: An Experimental Test of Five Strategies from the Revelation Risk Model.

Guided by the revelation risk model, we conducted an online experiment ( = 400) to assess five strategies (i.e. initiate, response, third-person disclosure, humor, evidence) used to hypothetically disclose two types of sexual dysfunction (SD) - vulvovaginal pain (VVP) and erectile dysfunction (ED) - in romantic relationships of six months or less.

'Mind your head', tackle characteristics associated with concussions in rugby league: A case-control study.

Objectives: Identify tackle characteristics associated with concussions in male professional rugby league.

Design: Case-control study.

Methods: Tackles resulting in 196 clinically diagnosed concussions and 6592 non-concussive tackles were analysed, from the men's rugby league Super League between 2018 and 2022.

A review of current and proposed behavioral nudge strategies to improve the readiness of the United States military.

This review discusses findings on the use of behavioral nudges in both the Canadian and U.S. military.

Inter-alpha Inhibitor Proteins Modulate Microvascular Endothelial Components and Cytokines After Exposure to Hypoxia-Ischemia in Neonatal Rats.

Inter-alpha inhibitor proteins (IAIPs) are neuroprotective and attenuate lipopolysaccharide (LPS)-mediated blood-brain barrier (BBB) disruption in neonatal rodents. We investigated some mechanism(s) fundamental to neuroprotection by IAIPs including changes in cerebral endothelial components and inflammation. Postnatal day-7 rats exposed to sham surgery and placebo or carotid ligation plus 8% FiO (90 min) were given IAIPs (30 or 60 mg/kg) or placebo and were killed 6, 12, 24, or 36 h after hypoxia-ischemia (HI).

Honor ideology and private firearm ownership in US active-duty soldiers.

Objectives: This study investigated whether honor ideology, or a belief that one's reputation must be defended at all costs, is related to firearms ownership in soldiers.

Methods: N=301 active-duty soldiers completed online self-report measures in this cross-sectional study.

Results: Honor ideology was higher in soldiers who privately own a firearm compared with those who do not currently own and do not plan to after military separation.

Revealing the Demographic History of the European Nightjar ().

A species' demographic history gives important context to contemporary population genetics and a possible insight into past responses to climate change; with an individual's genome providing a window into the evolutionary history of contemporary populations. Pairwise sequentially Markovian coalescent (PSMC) analysis uses information from a single genome to derive fluctuations in effective population size change over the last ~5 million years. Here, we apply PSMC analysis to two European nightjar () genomes, sampled in Northwest and Southern Europe, with the aim of revealing the demographic history of nightjar in Europe.

Training and Match-Related Head Acceleration Events in Top Level Domestic Senior Women's and Men's Rugby Union: A Multi-League Instrumented Mouthguard Study.

The aim of this study was to investigate the difference in head acceleration event (HAE) incidence between training and match-play in women's and men's players competing at the highest level of domestic rugby union globally. Players from Women's (Premiership Women's Rugby, Farah Palmer Cup) and Men's (Premiership Rugby, Currie Cup) rugby union competitions wore instrumented mouthguards during matches and training sessions during the 2022/2023 seasons. Peak linear (PLA) and angular (PAA) acceleration were calculated from each HAE and included within generalized linear mixed-effects models.

The application of match-event and instrumented mouthguard data to inform match limits: An example using rugby union Premiership and rugby league Super League data from England.

The study aimed to illustrate how contact (from match-event data) and head acceleration event (HAE) (from instrumented mouthguard [iMG]) data can be combined to inform match limits within rugby. Match-event data from one rugby union and rugby league season, including all competitive matches involving players from the English Premiership and Super League, were used. Playing exposure was summarised as full game equivalents (FGE; total minutes played/80).
