Common Patterns and Unique Threats in Antimicrobial Resistance as Demonstrated by Global Gonococcal Surveillance.

The rapid emergence of antimicrobial-resistant strains of Neisseria gonorrhoeae threatens treatment options and control efforts. The Uniformed Services University Gonococcal Reference Laboratory and Repository of the Global Emerging Infections Surveillance Program receives isolates from several geographically distinct regions worldwide. We analyzed 962 isolates collected during 2014-2022 for genomic and phenotypic antimicrobial resistance.

Increasing the uptake of advance care directives through staff education and one-on-one support for people facing end-of-life.

Background: An advance care plan outlines a patient's wishes regarding medical treatment or goals of care in the case that they become unable to communicate or to make decisions. An advance care directive (ACD) is an advance care plan that has been formally recorded and has legal status. Despite ACDs playing an important role in person-centred end-of-life care, an earlier retrospective medical records audit demonstrated that only 11% (58/531) of people who died due to a terminal illness had an ACD.

Intraspecific venom variation in the medically important puff adder (Bitis arietans): Comparative venom gland transcriptomics, in vitro venom activity and immunological recognition by antivenom.

Background: Variation in snake venoms is well documented, both between and within species, with intraspecific venom variation often correlated with geographically distinct populations. The puff adder, Bitis arietans, is widely distributed across sub-Saharan Africa and into the Arabian Peninsula where it is considered a leading cause of the ~310,000 annual snakebites across the region, with its venom capable of causing substantial morbidity and mortality. Despite its medical importance and wide geographic distribution, there is little known about venom variation between different B.

Molecular dissection of cobra venom highlights heparinoids as an antidote for spitting cobra envenoming.

Snakebites affect about 1.8 million people annually. The current standard of care involves antibody-based antivenoms, which can be difficult to access and are generally not effective against local tissue injury, the primary cause of morbidity.

Growth and body composition of dairy calves fed only milk replacer at 3 intakes.

Determination of energy requirements for growth depends on measuring the composition of BW gain. Previous studies have shown that the composition of gain can be altered in young dairy calves by the composition of the milk replacer diet. Here, our objective was to determine body composition and the composition of empty body gain in young calves fed increasing amounts of a milk replacer containing adequate CP.

Dermonecrosis caused by a spitting cobra snakebite results from toxin potentiation and is prevented by the repurposed drug varespladib.

Snakebite envenoming is a neglected tropical disease that causes substantial mortality and morbidity globally. The venom of African spitting cobras often causes permanent injury via tissue-destructive dermonecrosis at the bite site, which is ineffectively treated by current antivenoms. To address this therapeutic gap, we identified the etiological venom toxins in venom responsible for causing local dermonecrosis.

Multi-species biofilms of environmental microbiota isolated from fruit packing facilities promoted tolerance of to benzalkonium chloride.

may survive and persist in food processing environments due to formation of complex multi-species biofilms of environmental microbiota that co-exists in these environments. This study aimed to determine the effect of selected environmental microbiota on biofilm formation and tolerance of to benzalkonium chloride in formed biofilms. The studied microbiota included bacterial families previously shown to co-occur with in tree fruit packing facilities, including , and Biofilm formation ability and the effect of formed biofilms on the tolerance of to benzalkonium chloride was measured in single- and multi-family assemblages.

A validation of placental pathology reports by ethnicity in New Zealand, through systematic analysis of histological slides.

Introduction: Reliability studies of placental examination have shown differing interobserver agreement for certain pathological features, a lack of uniform reporting criteria and variable experience among pathologists. In previous analyses we have shown that placental pathology differs by ethnicity. This validation study was performed to investigate whether bias related to ethnicity is a feature of placental pathology reporting in New Zealand (NZ).

Repurposed drugs and their combinations prevent morbidity-inducing dermonecrosis caused by diverse cytotoxic snake venoms.

Morbidity from snakebite envenoming affects approximately 400,000 people annually. Tissue damage at the bite-site often leaves victims with catastrophic life-long injuries and is largely untreatable by current antivenoms. Repurposed small molecule drugs that inhibit specific snake venom toxins show considerable promise for tackling this neglected tropical disease.

Machine-learning guided Venom Induced Dermonecrosis Analysis tooL: VIDAL.

Snakebite envenoming is a global public health issue that causes significant morbidity and mortality, particularly in low-income regions of the world. The clinical manifestations of envenomings vary depending on the snake's venom, with paralysis, haemorrhage, and necrosis being the most common and medically relevant effects. To assess the efficacy of antivenoms against dermonecrosis, a preclinical testing approach involves in vivo mouse models that mimic local tissue effects of cytotoxic snakebites in humans.

Towards a framework for interoperability and reproducibility of predictive models.

The development and deployment of machine learning (ML) models for biomedical research and healthcare currently lacks standard methodologies. Although tools for model replication are numerous, without a unifying blueprint it remains difficult to scientifically reproduce predictive ML models for any number of reasons (e.g.

Care pathway analysis and evidence gaps in adult-onset Still's disease: interviews with experts from the UK, France, Italy, and Germany.

Introduction: Adult-onset Still's disease (AOSD) is a rare systemic inflammatory disease of unknown etiology. Published AOSD data are limited, and clinical guidelines were lacking until recently. Managing AOSD remains largely empirical with uncertainties and high variability about the optimal care pathway.

mutation in humans with pubertal failure alters GnRH transcript expression.

Idiopathic hypogonadotropic hypogonadism (IHH) is characterized by the absence of pubertal development and subsequent impaired fertility often due to gonadotropin-releasing hormone (GnRH) deficits. Exome sequencing of two independent cohorts of IHH patients identified 12 rare missense variants in in 15 patients. encodes two distinct isoforms.

Design and Evaluation of an Interprofessional Preceptor Development Mini-Fellowship Program.

Introduction: Health professions preceptors require skills and knowledge to effectively meet the educational needs of interprofessional students in clinical environments. We implemented a mini-fellowship program to enhance the knowledge, skills, and self-efficacy of preceptors teaching students and applying quality improvement (QI) methods across disciplines and patient care settings.

Methods: The design, implementation, and evaluation of the program were informed by the faculty development literature, principles of adult learning, and preceptor needs.

Azomethine-Containing Pyrrolo[3,2-b]pyrrole Copolymers for Simple and Degradable Conjugated Polymers.

Conjugated polymers have received significant attention as potentially lightweight and highly tailorable alternatives to inorganic semiconductors, but their synthesis is often complex, produces toxic byproducts, and they are not typically designed to be degradable or recyclable. These drawbacks necessitate dedicated efforts to discover materials with design motifs that enable targeted and efficient degradation of conjugated polymers. In this vein, the synthetic simplicity of 1,4-dihydropyrrolo[3,2-b]pyrroles (DHPPs) is exploited to access azomethine-containing copolymers via a benign acid-catalyzed polycondensation protocol.

Placental pathology findings in perinatal deaths from 28 weeks gestation in Aotearoa New Zealand.

Introduction: Women of South Asian ethnicity are overrepresented in adverse pregnancy outcome across high-income countries, including those related to placental dysfunction. It has been hypothesised that placental aging occurs at earlier gestation in South Asian pregnancies. We aimed to identify differences in placental pathology among perinatal deaths ≥28 weeks gestation, between South Asian, Māori and New Zealand (NZ) European women in Aotearoa NZ, with a focus on women of South Asian ethnicity.

Placental pathology findings amongst extremely preterm perinatal deaths in Aotearoa New Zealand.

Introduction: Women of South Asian ethnicity are overrepresented in adverse pregnancy outcomes across high-income countries, including placental dysfunction and antepartum haemorrhage. As the burden of mortality is highest for extremely preterm infants, we aimed to identify any differences in placental pathology among perinatal deaths from 20 to 27 weeks gestation between South Asian, Māori and New Zealand (NZ) European women in Aotearoa NZ, with a focus on women of South Asian ethnicity.

Methods: Placental pathology reports and clinical data from perinatal deaths between 2008 and 2017 were provided by the NZ Perinatal and Maternal Mortality Review Committee, blinded and analysed by an experienced perinatal pathologist using the Amsterdam Placental Workshop Group Consensus Statement criteria.

Proteomics and histological assessment of an organotypic model of human skin following exposure to Naja nigricollis venom.

Snakebite envenoming was reintroduced as a Category A Neglected Tropical Disease by the World Health Organization in 2017. Since then, increased attention has been directed towards this affliction and towards the development of a deeper understanding of how snake venoms exert their toxic effects and how antivenoms can counter them. However, most of our in vivo generated knowledge stems from the use of animal models which do not always accurately reflect how the pathogenic effects of snake venoms manifest in humans.
