Hidden Trauma: An Analysis of the Identification of Contusions on Different Skin Tones.

While abrasions and lacerations are typically easily identified, darker pigmentation of the skin may obscure contusions. Forensic pathology literature shows a disproportionate number of illustrations of contusions on lighter skin tones compared to darker ones. Skin and soft tissue dissection is the most reliable method to confirm contusions.

Moiré-driven topological electronic crystals in twisted graphene.

In a dilute two-dimensional electron gas, Coulomb interactions can stabilize the formation of a Wigner crystal. Although Wigner crystals are topologically trivial, it has been predicted that electrons in a partially filled band can break continuous translational symmetry and time-reversal symmetry spontaneously, resulting in a type of topological electron crystal known as an anomalous Hall crystal. Here we report signatures of a generalized version of the anomalous Hall crystal in twisted bilayer-trilayer graphene, whose formation is driven by the moiré potential.

Frailty and Mortality Risk Among Dogs with Extreme Longevity: Development and Predictive Validity of a Clinical Frailty Index in the Exceptional Aging in Rottweilers Study.

Frailty refers to a state of increased vulnerability to mortality and other adverse outcomes as a consequence of age-related decline in physiologic reserve and function. Comparative biomedical scientists are relied upon to innovate approaches to enhance understanding of the similarities and differences between humans and other animal species that can impact healthy aging. The research aim of this study was to develop a clinical frailty index (FI) in the Exceptional Aging in Rottweilers Study (EARS) and test its ability to predict all-cause mortality in elderly dogs.

Topological flat bands in a family of multilayer graphene moiré lattices.

Moiré materials host a wealth of intertwined correlated and topological states of matter, all arising from flat electronic bands with nontrivial quantum geometry. A prominent example is the family of alternating-twist magic-angle graphene stacks, which exhibit symmetry-broken states at rational fillings of the moiré band and superconductivity close to half filling. Here, we introduce a second family of twisted graphene multilayers made up of twisted sheets of M- and N-layer Bernal-stacked graphene flakes.

Accelerometer-Measured Volumes of Moderate-to-Vigorous Physical Activity and Functional Fitness in Older Adults.

The objective of this study is to investigate the association between different volumes of accelerometer-measured moderate-to-vigorous physical activity (MVPA) and functional fitness in older adults in a cross-sectional study (n = 242; 66 ± 5 years; 80% women). MVPA was assessed by accelerometer for 1 week. Based on the MVPA recommendations, the participants were classified as: (a) inactive (<50 min/week), (b) somewhat active (50-99 min/week), (c) moderately active (100-149 min/week), and (d) active (≥150 min/week).

Nurse-led framework to improve the safety and quality of residential aged care (HIRAID® Aged Care): protocol for a stepped-wedge cluster randomised controlled trial.

Background: The health issues experienced by older people can often be severe and complex, and an increasing number are using residential aged care services to meet their care needs. High-quality nursing care is fundamental to the health and safety of aged care residents and is contingent on nurses' accurate assessment, informed decision-making, and delivery of timely interventions. However, the role of the aged care nurse is often challenging, impeded by factors such as understaffing, high workloads, and a lack of access to clinical infrastructure and resources.

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.

Comparison of Cranial Cruciate Ligament Rupture Incidence among Parous and Nulliparous Rottweiler Bitches: Evidence from a Lifetime Cohort Study Supporting a Paradigm of Pregnancy-Associated Protection against Subsequent Non-Reproductive Disease Outcomes.

Emerging evidence in women supports the notion that pregnancy may reset disease resistance, thereby providing protection against subsequent adverse health outcomes, but this hypothesis has not been adequately explored in domestic dogs. Cranial cruciate ligament (CCL) rupture is a degenerative orthopedic disease that frequently affects pet dogs, and its risk has been associated with disruption of the reproductive hormone axis. Our research team is conducting a lifetime cohort study of purebred Rottweilers in North America that have lived 30% longer than breed-average.

Impact of next-generation sequencing vs polymerase chain reaction testing on payer costs and clinical outcomes throughout the treatment journeys of patients with metastatic non-small cell lung cancer.

Background: For patients with metastatic non-small cell lung cancer (mNSCLC), next-generation sequencing (NGS) biomarker testing has been associated with a faster time to appropriate targeted therapy and more comprehensive testing relative to polymerase chain reaction (PCR) testing. However, the impact on payer costs and clinical outcomes during patients' treatment journeys has not been fully characterized.

Objective: To assess the costs and clinical outcomes of NGS vs PCR biomarker testing among patients with newly diagnosed de novo mNSCLC from a US payers' perspective.

Identifying Risk Factors for Presarcopenia in Early Middle Age.

Objective: This study aimed to determine whether risk factors for presarcopenia can be identified in a sample of early middle-aged men and women.

Design: Prospective study.

Setting: Longitudinal data from the Dunedin Multidisciplinary Health and Development Study were used to investigate the relationship between presarcopenia at age 45 years and selected early markers at ages 26, 32, and 38 years.

Analysis of the genetic variance of fibre diameter measured along the wool staple for use as a potential indicator of resilience in sheep.

Background: The effects of environmental disturbances on livestock are often observed indirectly through the variability patterns of repeated performance records over time. Sheep are frequently exposed to diverse extensive environments but currently lack appropriate measures of resilience (or sensitivity) towards environmental disturbance. In this study, random regression models were used to analyse repeated records of the fibre diameter of wool taken along the wool staple (bundle of wool fibres) to investigate how the genetic and environmental variance of fibre diameter changes with different growing environments.

Sudden cardiac death due to an obstructive large right atrial myxoma.

Sudden cardiac death is a phenomenon that affects more than 200,000 individuals annually in the United States. Among sudden cardiac deaths, only a fractionally small portion is thought to be attributable to intracardiac neoplasms. Though rarely implicated as the primary cause of death, cardiac myxomas are the most common benign neoplasms of the heart and have been known to cause death due to multifactorial embolic events, fatal arrhythmias, and frank obstructive events.

A widespread electrical brain network encodes anxiety in health and depressive states.

In rodents, anxiety is charactered by heightened vigilance during low-threat and uncertain situations. Though activity in the frontal cortex and limbic system are fundamental to supporting this internal state, the underlying network architecture that integrates activity across brain regions to encode anxiety across animals and paradigms remains unclear. Here, we utilize parallel electrical recordings in freely behaving mice, translational paradigms known to induce anxiety, and machine learning to discover a multi-region network that encodes the anxious brain-state.

Case-study: A wicked way to address family violence in a regional setting in Western Australia.

Can step count be used to identify older adults with high sedentary time and low moderate-to-vigorous physical activity?

Introduction: Combined high sedentary time (ST) and low moderate-to-vigorous physical activity (MVPA) has been associated with adverse cardiovascular events. However, accurately assessing ST and MVPA in older adults is challenging in clinical practice.

Purpose: To investigate whether step count can identify older adults with unhealthier movement behavior (high ST/low MVPA) and poorer cardiometabolic profile.

Factors that support children and young people to express their views and to have them heard in healthcare: An inductive qualitative content analysis.

Despite development of healthcare charters supporting Article 12 of The United Nations Convention on the Rights of the Child, children and young people remain largely silenced in discussions about their healthcare. This article is based on the premise that children and young people should be able to exercise their right to express their views and be heard in all matters that affect their lives. This study examined children's and young people's experiences of expressing their views and having them heard in an Australian healthcare context.

Association of 'Tortoise' and 'Hare' movement behavior patterns with cardiometabolic health, body composition, and functional fitness in older adults.

We investigated the association of movement behavior patterns with cardiometabolic health, body composition, and functional fitness in older adults. A total of 242 older adults participated of this cross-sectional study. Sedentary time, light physical activity (LPA) and moderate-vigorous physical activity (MVPA), steps/day, and step cadence were assessed by accelerometry.

Cost of genetic testing, delayed care, and suboptimal treatment associated with polymerase chain reaction versus next-generation sequencing biomarker testing for genomic alterations in metastatic non-small cell lung cancer.

Aims: To assess US payers' per-patient cost of testing associated with next-generation sequencing (NGS) versus polymerase chain reaction (PCR) biomarker testing strategies among patients with metastatic non-small cell lung cancer (mNSCLC), including costs of testing, delayed care, and suboptimal treatment initiation.

Validation of reaction norm breeding values for robustness in Australian sheep.

Background: There can be variation between animals in how stable their genetic merit is across different environments due to genotype-by-environment (G×E) interactions. This variation could be used in breeding programs to select robust genotypes that combine high overall performance with stable genetic ranking across environments. There have been few attempts to validate breeding values for robustness in livestock, although this is a necessary step towards their implementation in selection decisions.
