Alcohol drinking is attenuated by PDE4 inhibition but partial microglia depletion is not sufficient to block stress-induced escalation of alcohol intake in female mice.

Stress is a major contributing factor to binge drinking and development of alcohol use disorders (AUD), particularly in women. Both stress and chronic ethanol can enhance neuroinflammatory processes, which may dysregulate limbic circuits involved in ethanol reinforcement. Clinical and preclinical studies have identified sex differences in alcohol intake in response to neuroinflammatory triggers.

Equity in breast density notification in Australia: A focus group study exploring the impact and needs amongst culturally and linguistically diverse (CALD) women.

Objectives: Previous research suggests a one-size-fits-all approach to breast density notification may disadvantage culturally and linguistically diverse (CALD) women. This study aimed to qualitatively explore CALD women's understanding and views of breast density, attitudes towards health services access, acceptability of notification and preferences for breast density communication ahead of population-based notification in Australia.

Methods: Online focus groups were conducted with CALD women of breast screening age (40-74 years) who spoke one of the five languages with the lowest English proficiency in Australia (Korean, Mandarin, Cantonese, Vietnamese and Arabic).

Examining Longitudinal Relations Between Eating Disorder Symptoms and Negative Emotion Variability in Military Members.

Up to a third of service members and Veterans experience disordered eating. Disordered eating can be maintained through negative reinforcement of painful and unpleasant emotions such as guilt, shame, sadness, and hostility. Hostility is a negative emotion that may be particularly relevant for service members and Veterans, yet hostility's relation to disordered eating remains understudied.

Patent landscape of small molecule inhibitors of METTL3 (2020-present).

Introduction: Methyltransferase-like protein 3 (METTL3), in complex with METTL14, is the key 'writer' protein for RNA mA methylation, accounting for almost all mRNA mA modifications. Recent studies reveal that METTL3 is implicated in the development and progression of various types of cancers. Targeting METTL3 with small molecule inhibitors represents a promising therapeutic strategy for cancer.

Neuro-immunobiology and treatment assessment in a mouse model of anti-NMDAR encephalitis.

Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is a disorder mediated by autoantibodies against the GluN1 subunit of NMDAR. It occurs with severe neuropsychiatric symptoms that often improve with immunotherapy. Clinical studies and animal models based on patients' antibody transfer or NMDAR immunization suggest that the autoantibodies play a major pathogenic role.

Short-Term Effects of Attaching Animal-Borne Devices on the Behavior of Juvenile Green Turtles.

The use of animal-borne devices (= biologgers) has revolutionized the study of marine megafauna, yet there remains a paucity of data concerning the behavioral and physiological impacts of biologger attachment and retention. Here, we used animal-borne cameras to characterize the behavior and dive duration of juvenile green turtles () in The Bahamas for up to 210 min after biologger deployment ( = 58). For a "control," we used unoccupied aerial vehicles (UAVs) to collect comparable data from nonhandled green turtles ( = 25) in the same habitats.

Pancreaticoduodenectomy in trauma patients with grade IV-V duodenal or pancreatic injuries: a post hoc analysis of an EAST multicenter trial.

Introduction: The utility of pancreaticoduodenectomy (PD) for high-grade traumatic injuries remains unclear and data surrounding its use are limited. We hypothesized that PD does not result in improved outcomes when compared with non-PD surgical management of grade IV-V pancreaticoduodenal injuries.

Methods: This is a retrospective, multicenter analysis from 35 level 1 trauma centers from January 2010 to December 2020.

Exploring Congruence Between Patient and Clinician Expectations of Benefit in the Non-Surgical Management of Common Musculoskeletal Conditions in Tertiary Care.

Background: Patient and clinician expectations of benefit from recommended management approaches may potentially impact the success of managing musculoskeletal conditions.

Methods: This was a multisite study in an advanced practice musculoskeletal service across Queensland, Australia. Relationships between patient and clinician (advanced physiotherapy practitioner) expectations of benefit, patient characteristics, and clinical outcome recorded 6 months later were explored with regression analysis in 619 patients undergoing non-surgical multidisciplinary care for either knee osteoarthritis (n = 286), low back pain (n = 249) or shoulder impingement syndrome (n = 84).

In-Cage Recombination Facilitates the Enantioselective Organocatalytic [1,2]-Rearrangement of Allylic Ammonium Ylides.

The [1,2]-rearrangement of allylic ammonium ylides is traditionally observed as a competitive minor pathway alongside the thermally allowed [2,3]-sigmatropic rearrangement. Concerted [1,2]-rearrangements are formally forbidden, with these processes believed to proceed through homolytic C-N bond fission of the ylide, followed by radical-radical recombination. The challenges associated with developing a catalytic enantioselective [1,2]-rearrangement of allylic ammonium ylides therefore lie in biasing the reaction pathway to favor the [1,2]-reaction product, alongside controlling a stereoselective radical-radical recombination event.

Plasma Aβ/Aβ is sensitive to early cerebral amyloid accumulation and predicts risk of cognitive decline across the Alzheimer's disease spectrum.

Introduction: The availability of amyloid beta (Aβ) targeting therapies for Alzheimer's disease (AD) is increasing the demand for scalable biomarkers that are sensitive to early cerebral Aβ accumulation.

Methods: We evaluated fully-automated Lumipulse plasma Aβ/Aβ immunoassays for detecting cerebral Aβ in 457 clinically unimpaired (CU) and clinically impaired (CI) Stanford Alzheimer's Disease Research Center (Stanford ADRC) participants and 186 CU in the Stanford Aging and Memory Study (SAMS). Longitudinal change in ADRC plasma Aβ/Aβ and cognition and cross-sectional associations with SAMS memory and tau positron emission tomography (PET) were examined.

Midbrain dopamine drives splenic immunity through a brain-to-body circuit.

Midbrain dopamine neurons are well-known to shape central nervous system function, yet there is growing evidence for their influence on the peripheral immune systems. Here we demonstrate that midbrain dopamine neurons form a circuit to the spleen via a multisynaptic pathway from the dorsal vagal complex (DVC) through the celiac ganglion. Midbrain dopamine neurons modulate the activity of D1-like and D2-like dopamine receptor-expressing DVC neurons.

The importance of microbiology reference laboratories and adequate funding for infectious disease surveillance.

In this Viewpoint, we emphasise the importance of microbiology reference laboratories and highlight the types of digital data and expertise they provide, which benefit national and international public health.

Stress reactivity moderates the association between stressful life events and depressive symptoms in adolescents: Results from a population-based study.

Background: A large body of evidence links stressful life events with depression. However, little is understood about the role of perceived impact in this association.

Methods: We performed regression analysis to investigate whether self-reported stress reactivity (derived by regressing the impact-weighted life event score on the unweighted score) moderated the association between stressful life events and depressive symptoms in adolescents from the Avon Longitudinal Study of Parents and Children cohort (n = 4791), controlling for age at outcome, sex, ethnicity, and maternal education.

Maximizing insights from longitudinal epigenetic age data: simulations, applications, and practical guidance.

Background: Epigenetic age (EA) is an age estimate, developed using DNA methylation (DNAm) states of selected CpG sites across the genome. Although EA and chronological age are highly correlated, EA may not increase uniformly with time. Departures, known as epigenetic age acceleration (EAA), are common and have been linked to various traits and future disease risk.

Patients Discharged "Against Medical Advice" More than Once: A Cross-Sectional Descriptive Analysis of a Vulnerable Population.

Background: Patients who have been discharged "against medical advice" (AMA) are at increased risk of morbidity and mortality, but there is little research about patients who have had more than one AMA discharge.

Objective: We aimed to describe the socio-demographic and clinical characteristics of patients with more than one AMA discharge.

Design: We conducted a cross-sectional, retrospective chart review of a sample of adult patients who were discharged AMA more than once between 2016 and 2021 and abstracted detailed characteristics of this sample.

Anakinra in relapsing polychondritis: a case report and review of the literature.

Relapsing polychondritis is rare and affects non-synovial fibrocartilage. Currently, there is a paucity of treatment algorithms, especially for those with refractory disease. A middle-aged man presented with polychondritis affecting the nose, ears, joints, and larynx.

A service evaluation of the implementation of a novel digital intervention for hypertension self-monitoring and management system in primary care (SHIP): protocol for a mixed methods study.

Background: Hypertension is a key risk factor for death and disability, and blood pressure reduction is associated with significant reductions in cardiovascular risk. Large trials have shown that interventions including self-monitoring of blood pressure can reduce blood pressure but real-world data from wider implementation are lacking.

Aim: The self-monitoring and management service evaluation in primary care (SHIP) study will evaluate a novel digital intervention for hypertension management and medication titration platform ("Hypertension-Plus") that is currently undergoing initial implementation into primary care in several parts of the UK.

Expediting pathogen genomics adoption for enhanced foodborne disease surveillance in Africa.

The role of genomics in public health surveillance has been accentuated by its crucial contributions during the COVID-19 pandemic, demonstrating its potential in addressing global disease outbreaks. While Africa has made strides in expanding multi-pathogen genomic surveillance, the integration into foodborne disease (FBD) surveillance remains nascent. Here we highlight the critical components to strengthen and scale-up the integration of whole genome sequencing (WGS) in foodborne disease surveillance across the continent.

Methods: Forty-three females initiating treatment with palbociclib participated in a two-armed prospective randomized clinical trial. Participants were randomized into the control ( = 21) and intervention groups ( = 22) from January 2020 to January 2023.

Contemporary treatment patterns of overweight and obesity: insights from the Mass General Brigham health care system.

Objective: The objective of this study was to describe the prevalence of obesity, obesity-related conditions (ORCs), and antiobesity medication (AOM) eligibility and prescribing practice among eligible patients in a large health care system.

Methods: In this cross-sectional analysis of the multicenter Mass General Brigham health care system (Boston, Massachusetts) spanning 2018 to 2022, adults eligible for AOMs (BMI ≥ 30 kg/m or BMI 27-29.9 kg/m with ≥1 ORC) were identified.

Characterization of intact FeoB in a lipid bilayer using styrene-maleic acid (SMA) copolymers.

The acquisition of ferrous iron (Fe) is crucial for the survival of many pathogenic bacteria living within acidic and/or anoxic conditions such as Vibrio cholerae, the causative agent of the disease cholera. Bacterial pathogens utilize iron as a cofactor to drive essential metabolic processes, and the primary prokaryotic Fe acquisition mechanism is the ferrous iron transport (Feo) system. In V.

Characterizing phenotypes and clinical and health utilization associations of young people with chronic pain: latent class analysis using the electronic Persistent Pain Outcomes Collaboration database.

Using the Australiasian electronic Persistent Pain Outcomes Collaboration, a binational pain registry collecting standardized clinical data from paediatric ePPOC (PaedsePPOC) and adult pain services (AdultePPOC), we explored and characterized nationally representative chronic pain phenotypes and associations with clinical and sociodemographic factors, health care utilization, and medicine use of young people. Young people ≥15.0 and <25.

Three-Dimensional Vascular Structure of Caudal and Dorsal Fins of a Dwarf Sperm Whale.

Previous studies have described two distinct vascular systems in cetacean fins. However, these studies have been limited to Delphinoidea species, with little information on their three-dimensional structures. In this study, the anatomical analysis of the caudal and dorsal fins of a dwarf sperm whale was conducted using X-ray computed tomography and gross dissection with staining, providing the first confirmation of the two vascular systems in the fins of the family Kogiidae.
