Genomic and Acoustic Biogeography of the Iconic Sulphur-crested Cockatoo Clarifies Species Limits and Patterns of Intraspecific Diversity.

Many highly recognizable species lack genetic data important for conservation due to neglect over their hyperabundance. This likely applies to the Sulfur-crested Cockatoo (Cacatua galerita), one of the world's most iconic parrots. The species is native to Australia, New Guinea, and some surrounding Melanesian islands of the latter.

Hepatitis C Virus Infection in Pregnant Individuals with Opioid Use Disorder and Its Association with Preterm Birth.

Objective:  Both hepatitis C virus (HCV) and opioid use disorder (OUD) have been associated with higher rates of preterm birth (PTB). It is unknown whether the higher prevalence of HCV in individuals with OUD may contribute to this association. The objective of this study is to evaluate the association between HCV and PTB in pregnant individuals with OUD.

Sexual and Reproductive Health Care after Gonadotoxic Treatment in Females at a Tertiary Pediatric Hospital.

Study Objectives: Recommendations from the Children's Oncology Group Long-Term Follow-Up (COG-LTFU) Guidelines for Survivors of Childhood, Adolescent, and Young Adult Cancer emphasize the importance of reproductive health care, yet little is known regarding adherence to these recommendations and non-fertility-related sexual and reproductive health (SRH) outcomes.

Methods: Follow-up of outcomes on the basis of the COG-LTFU guidelines was assessed in female patients who underwent fertility preservation consultation before gonadotoxic therapy between 2016 and 2022 at a single institution and were at least 6 months from treatment completion.

Results: We included 140 patients, with a mean time of 2.

Association between Individual versus Community-level Social Vulnerability and Neonatal Opioid Withdrawal Syndrome among Pregnant Individuals Receiving Buprenorphine for Opioid Use Disorder.

Objective: Individual patient-level measures of adverse social determinants of health are associated with neonatal opioid withdrawal syndrome (NOWS), but the relative impact of community-level adverse social determinants of health remains to be defined. We examined the association between community-level social vulnerability and NOWS among pregnant individuals receiving buprenorphine for opioid use disorder.

Study Design: We conducted a secondary analysis of an established cohort of pregnant individuals and their infants participating in a multidisciplinary prenatal/addiction care program from 2013 to 2021.

CIRCUST: A novel methodology for temporal order reconstruction of molecular rhythms; validation and application towards a daily rhythm gene expression atlas in humans.

The circadian system drives near-24-h oscillations in behaviors and biological processes. The underlying core molecular clock regulates the expression of other genes, and it has been shown that the expression of more than 50 percent of genes in mammals displays 24-h rhythmic patterns, with the specific genes that cycle varying from one tissue to another. Determining rhythmic gene expression patterns in human tissues sampled as single timepoints has several challenges, including the reconstruction of temporal order of highly noisy data.

Methods: Consecutive patients who were treated by ECPELLA with surgically implanted axillary Impella 5.

9 Supply of non-clinical ocular tissue from a tissue and eye services research tissue bank.

Introduction: NHS Blood and Transplant Tissue and Eye Services (TES) is a human multi-tissue, tissue bank supplying tissue for transplant to surgeons throughout the UK. In addition, TES provides a service to scientists, clinicians and tissue bankers by providing a range of non-clinical tissue for research, training and education purposes. A large proportion of the non-clinical tissues supplied is ocular tissue ranging from whole eyes, to corneas, conjunctiva, lens and posterior segments remaining after the cornea is excised.

3 Emergency salvage of time expired clinical corneas during the COVID-19 pandemic.

Introduction: Corneas for clinical use can be stored for a maximum of 28 days in organ culture medium after death. At the beginning of the COVID-19 pandemic in 2020 it became apparent that; a rare situation was arising in that clinical operations were being cancelled and that there would be a surplus of "clinical grade" corneas. Consequently, when the corneas reached the end of the storage period, if the tissue had appropriate consent, they were transferred to the Research Tissue Bank (RTB).

Objective: Evaluate maternal and neonatal outcomes in subsequent pregnancies for individuals initiated on MOUD in prior pregnancy.

Scoping review with textual narrative synthesis of the literature reporting stress and burn-out in specialist nurses: making the case for inflammatory bowel disease nurse specialists.

Objective: Inflammatory bowel disease clinical nurse specialists (IBD-CNSs) face increasing pressures due to rising clinical and patient demands, advanced complexity of work role, and minimal specialist management training and support. Stress and burn-out could undermine the stability of this workforce, disrupting clinical provision. We reviewed the literature on stress and burn-out to demonstrate the lack of evidence pertinent to IBD-CNSs and make the case for further research.

Light exposure during sleep impairs cardiometabolic function.

SignificanceAmbient nighttime light exposure is implicated as a risk factor for adverse health outcomes, including cardiometabolic disease. However, the effects of nighttime light exposure during sleep on cardiometabolic outcomes and the related mechanisms are unclear. This laboratory study shows that, in healthy adults, one night of moderate (100 lx) light exposure during sleep increases nighttime heart rate, decreases heart rate variability (higher sympathovagal balance), and increases next-morning insulin resistance when compared to sleep in a dimly lit (<3 lx) environment.

Further structural characterization of ovine forestomach matrix and multi-layered extracellular matrix composites for soft tissue repair.

Decellularized extracellular matrix (dECM)-based biomaterials are of great clinical utility in soft tissue repair applications due to their regenerative properties. Multi-layered dECM devices have been developed for clinical indications where additional thickness and biomechanical performance are required. However, traditional approaches to the fabrication of multi-layered dECM devices introduce additional laminating materials or chemical modifications of the dECM that may impair the biological functionality of the material.

Specialist inflammatory bowel disease nursing in the UK: current situation and future proofing.

Objective: To determine the impact to date of the ongoing Crohn's & Colitis UK inflammatory bowel disease (IBD) clinical nurse specialists (CNS) campaign.

Methods: A survey-based design was used. 2 questionnaires were sent to the UK IBD nursing community and promoted via nursing and clinical networks.

Androgen Receptor Is Dispensable for X-Zone Regression in the Female Adrenal but Regulates Post-Partum Corticosterone Levels and Protects Cortex Integrity.

Adrenal androgens are fundamental mediators of ovarian folliculogenesis, embryonic implantation, and breast development. Although adrenal androgen function in target tissues are well characterized, there is little research covering the role of androgen-signaling within the adrenal itself. Adrenal glands express AR which is essential for the regression of the X-zone in male mice.

Impact of circadian disruption on glucose metabolism: implications for type 2 diabetes.

The circadian system generates endogenous rhythms of approximately 24 h, the synchronisation of which are vital for healthy bodily function. The timing of many physiological processes, including glucose metabolism, are coordinated by the circadian system, and circadian disruptions that desynchronise or misalign these rhythms can result in adverse health outcomes. In this review, we cover the role of the circadian system and its disruption in glucose metabolism in healthy individuals and individuals with type 2 diabetes mellitus.

Modelling the Inflammatory Bowel Disease Specialist Nurse Workforce Standards by Determination of Optimum Caseloads in the UK.

Background And Aims: Crohn's disease and ulcerative colitis are the most common forms of inflammatory bowel disease [IBD], affecting 1 in 250 of the population in the UK. It is accepted that access to a specialist nurse service improves patient experience and outcome. National Standards for the Healthcare of People Who Have Inflammatory Bowel Disease [2013] defined the number of nurse specialists required at 1.

Dissection by genomic and plumage variation of a geographically complex hybrid zone between two Australian non-sister parrot species, Platycercus adscitus and Platycercus eximius.

The study of hybrid zones advances understanding of the speciation process, and approaches incorporating genomic data are increasingly used to draw significant conclusions about the impact of hybridisation. Despite the progress made, the complex interplay of factors that can lead to substantially variable hybridisation outcomes are still not well understood, and many systems and/or groups remain comparatively poorly studied. Our study aims to broaden the literature on avian hybrid zones, investigating a potentially geographically and temporally complex putative hybrid zone between two native Australian non-sister parrot species, the pale-headed and eastern rosellas (Platycercus adscitus and Platycercus eximius, respectively).
