Developing nurse and midwife centred rostering principles using co-design: a mixed-methods study.

Background: Current nursing and midwifery rosters are based on guidelines which may no longer adequately meet the needs of health services or staff and often result in decreased job satisfaction, poor health and wellbeing, and high turnover. Little is known about the rostering needs and preferences of contemporary nurses and midwives in Australia. The aim of this study was to identify the rostering concerns, needs and preferences of nurses and midwives, and co-design acceptable, equitable and feasible rostering principles.

A unified VCF data set from nearly 1,500 diverse maize accessions and resources to explore the genomic landscape of maize.

Efforts to capture and analyze maize nucleotide diversity have ranged widely in scope, but differences in reference genome version and software algorithms used in these efforts inhibit comparison, and these data are generally not available in an easy-to-use visualization platform for quick access and analysis. To address these issues, The Maize Genetics and Genomics Database has collaborated with maize researchers to offer variant data from a diverse set of 1,498 inbred lines, traditional varieties, and teosintes through a standardized variant-calling pipeline against version 5 of the B73 reference genome. The output was filtered for mapping quality, completeness, and linkage disequilibrium, and annotated based on variant effects relative to the B73 RefGen_v5 gene annotations.

Appendiceal Neoplasm in Conservatively Managed Acute Appendicitis: A Retrospective Observational Study.

Introduction Appendiceal neoplasms are more prevalent in patients ≥ 40 years old who present with complicated appendicitis, especially if managed conservatively. Routine interval appendicectomy is not recommended. Follow-up bowel screening using both a CT scan and colonoscopy is recommended.

Human Topoisomerase IIα Promotes Chromatin Condensation Via a Phase Transition.

Topoisomerase II (topo II) enzymes are essential enzymes known to resolve topological entanglements during DNA processing. Curiously, while yeast expresses a single topo II, humans express two topo II isozymes, topo IIα and topo IIβ, which share a similar catalytic domain but differ in their intrinsically disordered C-terminal domains (CTDs). During mitosis, topo IIα and condensin I constitute the most abundant chromosome scaffolding proteins essential for chromosome condensation.

Tools and Resources at the Maize Genetics and Genomics Database (MaizeGDB).

The Maize Genetics and Genomics Database (MaizeGDB) is the community resource for maize researchers, offering a suite of tools, informatics resources, and curated data sets to support maize genetics, genomics, and breeding research. Here, we provide an overview of the key resources available at MaizeGDB, including maize genomes, comparative genomics, and pan-genomics tools. This review aims to familiarize users with the range of options available for maize research and highlights the importance of MaizeGDB as a central hub for the maize research community.

The translocation activity of Rad54 reduces crossover outcomes during homologous recombination.

Homologous recombination (HR) is a template-based DNA double-strand break repair pathway that requires the selection of an appropriate DNA sequence to facilitate repair. Selection occurs during a homology search that must be executed rapidly and with high fidelity. Failure to efficiently perform the homology search can result in complex intermediates that generate genomic rearrangements, a hallmark of human cancers.

Functional annotation and meta-analysis of maize transcriptomes reveal genes involved in biotic and abiotic stress.

Background: Environmental stress factors, such as biotic and abiotic stress, are becoming more common due to climate variability, significantly affecting global maize yield. Transcriptome profiling studies provide insights into the molecular mechanisms underlying stress response in maize, though the functions of many genes are still unknown. To enhance the functional annotation of maize-specific genes, MaizeGDB has outlined a data-driven approach with an emphasis on identifying genes and traits related to biotic and abiotic stress.

Enhanced pan-genomic resources at the maize genetics and genomics database.

Pan-genomes, encompassing the entirety of genetic sequences found in a collection of genomes within a clade, are more useful than single reference genomes for studying species diversity. This is especially true for a species like Zea mays, which has a particularly diverse and complex genome. Presenting pan-genome data, analyses, and visualization is challenging, especially for a diverse species, but more so when pan-genomic data is linked to extensive gene model and gene data, including classical gene information, markers, insertions, expression and proteomic data, and protein structures as is the case at MaizeGDB.

Barriers and facilitators to pressure ulcer prevention behaviours by older people living in their own homes and their lay carers: a qualitative study.

Objective: To identify barriers and facilitators to pressure ulcer prevention behaviours in community-dwelling older people and their lay carers.

Design: Theoretically informed qualitative interviews with two-phase, deductive then inductive, thematic analysis.

Setting: The study was conducted in one geographical region in the UK, spanning several community National Health Service Trusts.

PanEffect: a pan-genome visualization tool for variant effects in maize.

Summary: Understanding the effects of genetic variants is crucial for accurately predicting traits and functional outcomes. Recent approaches have utilized artificial intelligence and protein language models to score all possible missense variant effects at the proteome level for a single genome, but a reliable tool is needed to explore these effects at the pan-genome level. To address this gap, we introduce a new tool called PanEffect.

Observation of parallel intersystem crossing and charge transfer-state dynamics in [Fe(bpy)] from ultrafast 2D electronic spectroscopy.

Transition metal-based charge-transfer complexes represent a broad class of inorganic compounds with diverse photochemical applications. Charge-transfer complexes based on earth-abundant elements have been of increasing interest, particularly the canonical [Fe(bpy)]. Photoexcitation into the singlet metal-ligand charge transfer (MLCT) state is followed by relaxation first to the ligand-field manifold and then to the ground state.

Maize Feature Store: A centralized resource to manage and analyze curated maize multi-omics features for machine learning applications.

The big-data analysis of complex data associated with maize genomes accelerates genetic research and improves agronomic traits. As a result, efforts have increased to integrate diverse datasets and extract meaning from these measurements. Machine learning models are a powerful tool for gaining knowledge from large and complex datasets.

Racial Differences in Nursing Home Quality of Life Among Residents Living With Alzheimer's Disease and Related Dementias.

ObjectivesAmong nursing home (NH) residents with Alzheimer's disease (AD) and AD-related dementias (AD/ADRD), racial/ethnic disparities in quality of care exist. However, little is known about quality of life (QoL). This study examines racial/ethnic differences in self-reported QoL among NH residents with AD/ADRD.

DNA curtains to visualize chromatin interactions.

Recent advances in single molecule imaging have allowed the evolution of biochemical techniques that directly visualize protein-DNA interactions in real-time. These techniques rely on diffraction limited total internal reflection microscopy (TIRFM), and have significantly improved our understanding of RNA transcription, DNA replication, homologous recombination, and general DNA repair in the context of chromatin. Here we described a general single molecule TIRFM technique called DNA curtains to directly visualize how enzymes function on chromatinized DNA.

Measuring Nursing Home Quality of Life: Validated Measures Are Poorly Correlated With Proxies From MDS and Quality of Life Deficiency Citationsl.

Objectives: Ensuring quality of life (QoL) is an important goal of person-centered nursing home care. The provision of person-centered care relies on information captured in the Minimum Data Set 3.0 (MDS).

Maize protein structure resources at the maize genetics and genomics database.

Protein structures play an important role in bioinformatics, such as in predicting gene function or validating gene model annotation. However, determining protein structure was, until now, costly and time-consuming, which resulted in a structural biology bottleneck. With the release of such programs AlphaFold and ESMFold, this bottleneck has been reduced by several orders of magnitude, permitting protein structural comparisons of entire genomes within reasonable timeframes.

Association mapping across a multitude of traits collected in diverse environments in maize.

Classical genetic studies have identified many cases of pleiotropy where mutations in individual genes alter many different phenotypes. Quantitative genetic studies of natural genetic variants frequently examine one or a few traits, limiting their potential to identify pleiotropic effects of natural genetic variants. Widely adopted community association panels have been employed by plant genetics communities to study the genetic basis of naturally occurring phenotypic variation in a wide range of traits.

Alternative COVID-19 mitigation measures in school classrooms: analysis using an agent-based model of SARS-CoV-2 transmission.

The SARS-CoV-2 epidemic has impacted children's education, with schools required to implement infection control measures that have led to periods of absence and classroom closures. We developed an agent-based epidemiological model of SARS-CoV-2 transmission in a school classroom that allows us to quantify projected infection patterns within primary school classrooms, and related uncertainties. Our approach is based on a contact model constructed using random networks, informed by structured expert judgement.

Evidence to Inform Policy and Practice: Mechanisms to Address Racial/Ethnic Disparities in Nursing Home Quality of Life.

Background And Objectives: Abundant evidence documents racial/ethnic disparities in access, quality of care, and quality of life (QoL) among nursing home (NH) residents who are Black, Indigenous, and people of color (BIPOC) compared with White residents. BIPOC residents are more likely to be admitted to lower quality NHs and to experience worse outcomes. Yet, little is known about processes for differences in QoL among residents receiving care in high-proportion BIPOC NHs.

Impact of the 2019/2020 Australian Megafires on Air Quality and Health.

The Australian 2019/2020 bushfires were unprecedented in their extent and intensity, causing a catastrophic loss of habitat, human and animal life across eastern-Australia. We use a regional air quality model to assess the impact of the bushfires on particulate matter with a diameter less than 2.5 μm (PM) concentrations and the associated health impact from short-term population exposure to bushfire PM.

Longitudinal Comparison of Stability and Sensitivity in Quality of Life Scores Among Nursing Home Residents With and Without Diagnoses of Alzheimer's Disease and Related Dementias.

Background And Objectives: Prevalence of nursing home residents with Alzheimer's disease and related dementias (ADRD) has increased along with a growing consensus that person-centered ADRD care in nursing homes should maximize quality of life (QoL). However, concerns about whether residents with ADRD can make appropriate QoL judgments persist. This study assesses the stability and sensitivity of a self-reported, multidomain well-being QoL measure for nursing home residents with and without ADRD.
