Stereodivergent Synthesis of the Vicinal Difluorinated Tetralin of Casdatifan Enabled by Ru-Catalyzed Transfer Hydrogenation.

We disclose a stereodivergent strategy to prepare difluorinated tetralins from γ-substituted tetralones via a combination of catalyst-controlled transfer hydrogenation and substrate-controlled fluorinations. This process is easily scalable and amenable to highly functionalized substrates, as demonstrated here in the late-stage synthesis of casdatifan, a clinical-stage inhibitor of hypoxia-inducible factor-2α. Analysis of the physicochemical properties of casdatifan, which features a difluoride, revealed a higher level of facial polarization compared to its difluoride isomers.

Prognostic Factors in 26 Cats Undergoing Surgery for Extra-Hepatic Biliary Obstruction.

Surgical management of feline extra-hepatic biliary obstruction (EHBO) has poor survival rates with few prognostic factors reported in the literature. The etiology and clinical findings of feline EHBO and their influence on short-(2 weeks-6 months) and long-term (>6 months) survival and prognosis were examined in an observational clinical retrospective study of 26 client-owned cats undergoing surgery for biliary obstruction at one institution between 2012 and 2020. The etiology of EHBO was determined in 21/26 cats, which included inflammatory causes (14/21), neoplastic causes (6/21), and a duodenal foreign body (1/21).

Redefining faculty workload metrics: A data-driven approach.

Background: Benchmarking faculty workload is key for equity, but a standard model like the Carnegie Unit, originally designed for student workload, does not fit all scenarios.

Methods: A novel Faculty Effort Data Collection Tool assessed whether the Carnegie Unit accurately reflected faculty effort in a graduate nursing program. Workload was evaluated course-by-course based on faculty self-reported hours.

Purpose in Life and Stress Reactivity.

Individuals with a stronger sense of purpose in life experience better health across the lifespan. This chapter describes one mechanism linking purpose to health, namely stress reactivity. Across survey, experimental, and daily diary studies, research demonstrates that sense of purpose may yield a homeostatic function, insofar that it helps individuals stay the course to progress toward their purpose in life.

Background: The American Association of Colleges of Nursing (AACN) and National Organization of Nurse Practitioner Faculties (NONPF) emphasize the role of clinical reasoning in nurse practitioner (NP) competencies. Evidence-based clinical reasoning is vital to patient safety. Collaborative technology tools can aid in assessing progress towards achieving clinical reasoning competency.

Seroreactivity against spp. differs between community cats and privately-owned cats in Hong Kong.

Leptospirosis is a bacterial zoonotic disease of major One Health significance and public health impact globally, with a wide host range including mammals, cetaceans and herpetofauna. This study aimed to determine seroprevalence, risk factors for seroreactivity and prevalence of urinary shedding among domestic cats in Hong Kong. Microagglutination testing of 22 serovars from 20 serogroups was performed on 738 sera from outdoor free-roaming "community" cats ( = 391) and privately-owned ( = 347) cats.

Meta-transcriptomic analysis of companion animal infectomes reveals their diversity and potential roles in animal and human disease.

Unlabelled: Companion animals such as cats and dogs harbor diverse microbial communities that can potentially impact human health due to close and frequent contact. To better characterize their total infectomes and assess zoonotic risks, we characterized the overall infectomes of companion animals (cats and dogs) and evaluated their potential zoonotic risks. Meta-transcriptomic analyses were performed on 239 samples from cats and dogs collected across China, identifying 24 viral species, 270 bacterial genera, and two fungal genera.

A stargate mechanism of genome delivery unveiled by cryogenic electron tomography.

Single-stranded DNA bacteriophages of the family are major components of the global virosphere. Microviruses are highly abundant in aquatic ecosystems and are prominent members of the mammalian gut microbiome, where their diversity has been linked to various chronic health disorders. Despite the clear importance of microviruses, little is known about the molecular mechanism of host infection.

The Effect of Music on Postoperative Agitation, Pain, and Opioid Use among Patients Undergoing Total Knee Replacement.

Background: Postoperative pain and agitation is an ongoing issue among patients undergoing total knee replacement (TKR). Use of complementary therapies such as music may improve outcomes when combined with medical therapy.

Aim: The purpose of this quality improvement (QI) initiative was to evaluate postoperative use of classical music among adult patients who have undergone TKR on reported agitation, pain, and opioid use.

Cultural stress and immigrant well-being: The role of sense of purpose.

Objectives: Immigrants face multiple forms of cultural stress that hold pernicious influences on their psychological well-being, including everyday discrimination, bicultural stressors, and negative context of reception from others. Research thus is needed to consider potential buffers and mitigating factors that may help immigrant adults in the face of cultural stress. The present studies evaluated a sense of purpose as one potential buffer.

CONCURRENT IRON OVERLOAD AND NEOPLASIA IN LESCHENAULT'S ROUSETTES (): A CASE SERIES.

This case series investigates a cluster of deaths in a captive colony of Leschenault's rousettes (). Six of seven bats that died between March and September 2021 were diagnosed postmortem with both iron overload (IO) and neoplasia, neither of which have previously been reported in this species. Iron status was assessed via hepatic histopathological grading, hepatic iron concentration, and, in two cases, serum iron concentration.

Risk Identification in Perinatal Health Care Settings via Technology-Based Recruitment Methods: Comparative Study.

Background: Digital screening and intervention tools have shown promise in the identification and reduction of substance use in health care settings. However, research in this area is impeded by challenges in integrating recruitment efforts into ongoing clinical workflows or staffing multiple study clinics with full-time research assistants, as well as by the underreporting of substance use.

Objective: The aim of the study is to evaluate pragmatic methods for facilitating study recruitment in health care settings by examining recruitment rates and participant characteristics using in-person-based versus flyer approaches.

Epidemiology of Pathogenic Retroviruses and Domestic Cat Hepadnavirus in Community and Client-Owned Cats in Hong Kong.

Understanding the local epidemiology of feline leukaemia virus (FeLV) and feline immunodeficiency virus (FIV) in Hong Kong will inform retrovirus prevention strategies. Domestic cat hepadnavirus (DCH), a novel hepatitis-B-like virus, is commonly detected among client-owned cats in Hong Kong, but community cats have not been studied. The aims of this study were to investigate the frequency and potential risk factors for (i) FeLV and FIV among community and client-owned cats and (ii) perform molecular detection of DCH among community cats in Hong Kong.

Physiology governing diatom vs. dinoflagellate bloom and decline in coastal Santa Monica Bay.

Algal blooms on the Southern California coast are typically dominated by diatom and dinoflagellate taxa, and are governed by their physiological responses to environmental cues; however, we lack a predictive understanding of the environmental controls underlying the establishment and persistence of these distinct bloom events. In this study, we examined gene expression among the numerically dominant diatom and dinoflagellate taxa during spring upwelling bloom events to compare the physiological underpinnings of diatom vs. dinoflagellate bloom dynamics.

An ethogram of acute pain behaviors in cats based on expert consensus.

An improved understanding of behaviors reflecting acute pain in cats is a priority for feline welfare. The aim of this study was to create and validate a comprehensive ethogram of acute pain behaviors in cats that can discriminate painful versus non-painful individuals. An inventory of behaviors (ethogram) with their respective descriptors was created based on a literature review of PubMed, Web of Science and CAB Abstracts databases.

Structural and functional changes of deep layer pyramidal neurons surrounding microelectrode arrays implanted in rat motor cortex.

Devices capable of recording or stimulating neuronal signals have created new opportunities to understand normal physiology and treat sources of pathology in the brain. However, it is possible that the tissue response to implanted electrodes may influence the nature of the signals detected or stimulated. In this study, we characterized structural and functional changes in deep layer pyramidal neurons surrounding silicon or polyimide-based electrodes implanted in the motor cortex of rats.

Infection in a Cat with Immune-Mediated Haemolytic Anaemia and Thrombocytopenia.

Tick-borne haemoparasite has been detected rarely in cats, in surveys of apparently healthy animals. In stored blood from a 6-year-old male-neutered domestic shorthair cat in Hong Kong, DNA was detected retrospectively using PCR for spp. 18S rRNA and mitochondrial cytochrome B genes, followed by sequencing and basic local alignment search tool (BLAST) analysis.

Observation of high-energy neutrinos from the Galactic plane.

The origin of high-energy cosmic rays, atomic nuclei that continuously impact Earth's atmosphere, is unknown. Because of deflection by interstellar magnetic fields, cosmic rays produced within the Milky Way arrive at Earth from random directions. However, cosmic rays interact with matter near their sources and during propagation, which produces high-energy neutrinos.
