Learning from COVID-19: strengthening Australia's research capacity through preparedness and collaboration.

The coronavirus disease 2019 (COVID-19) pandemic has highlighted that preparedness for and responsiveness to pandemics requires public health platforms and processes which are nimble and evidence-based and a research ecosystem which is rapidly responsive to the evolving needs of society and decision-makers. The national BEAT COVID-19 research consortium was funded in 2020 by the Snow Medical Research Foundation (Snow Medical). Its Expert Advisory Committee met with the consortium post-pandemic to summarise the research undertaken and to consider lessons learned through the research response to COVID-19 in Australia.

Critical care nurse leaders' moral distress: A qualitative descriptive study.

Background: Unit-based critical care nurse leaders (UBCCNL) play a role in exemplifying ethical leadership, addressing moral distress, and mitigating contributing factors to moral distress on their units. Despite several studies examining the experience of moral distress by bedside nurses, knowledge is limited regarding the UBCCNL's experience.

Research Aim: The aim of this study was to gain a deeper understanding of the lived experiences of Alabama UBCCNLs regarding how they experience, cope with, and address moral distress.

Critical care nurse leaders addressing moral distress: A qualitative study.

Background: Moral distress (MD) occurs when clinicians are constrained from taking what they believe to be ethically appropriate actions. When unattended, MD may result in moral injury and/or suffering. Literature surrounding how unit-based critical care nurse leaders address MD in practice is limited.

Promoting Competence in Nursing and Pharmacy Interprofessional Collaboration Through Telehealth Simulation.

Competence in interprofessional collaboration is essential for safe patient outcomes. This study examined the impact of an interprofessional telehealth pharmacology simulation on prelicensure nursing and pharmacy students' perceptions of interprofessional roles. A pretest-posttest design was used to compare participants' perceptions of interprofessional roles prior to and following the simulation.

Moral distress among nurse leaders: A qualitative systematic review.

Moral distress (MD) is well-documented within the nursing literature and occurs when constraints prevent a correct course of action from being implemented. The measured frequency of MD has increased among nurses over recent years, especially since the COVID-19 Pandemic. MD is less understood among nurse leaders than other populations of nurses.

Evaluation of the Australian first few X household transmission project for COVID-19.

Background: The Australian First Few X (FFX) Household Transmission Project for COVID-19 was the first prospective, multi-jurisdictional study of its kind in Australia. The project was undertaken as a partnership between federal and state health departments and the Australian Partnership for Preparedness Research on Infectious Disease Emergencies (APPRISE) and was active from April to October 2020.

Methods: We aimed to identify and explore the challenges and strengths of the Australian FFX Project to inform future FFX study development and integration into pandemic preparedness plans.

A Computational Approach to Identification of Candidate Biomarkers in High-Dimensional Molecular Data.

Complex high-dimensional datasets that are challenging to analyze are frequently produced through '-omics' profiling. Typically, these datasets contain more genomic features than samples, limiting the use of multivariable statistical and machine learning-based approaches to analysis. Therefore, effective alternative approaches are urgently needed to identify features-of-interest in '-omics' data.

An Update on Posterior Tarsal Tunnel Syndrome.

Posterior tarsal tunnel syndrome (PTTS) is an entrapment neuropathy due to compression of the tibial nerve or one of its terminal branches within the tarsal tunnel in the medial ankle. The tarsal tunnel is formed by the flexor retinaculum, while the floor is composed of the distal tibia, talus, and calcaneal bones. The tarsal tunnel contains a number of significant structures, including the tendons of 3 muscles as well as the posterior tibial artery, vein, and nerve.

Genes and evolutionary fates of the amanitin biosynthesis pathway in poisonous mushrooms.

The deadly toxin α-amanitin is a bicyclic octapeptide biosynthesized on ribosomes. A phylogenetically disjunct group of mushrooms in Agaricales (Amanita, Lepiota, and Galerina) synthesizes α-amanitin. This distribution of the toxin biosynthetic pathway is possibly related to the horizontal transfer of metabolic gene clusters among taxonomically unrelated mushrooms with overlapping habitats.

Value of consultation in establishing a public health research network: lessons from APPRISE.

Objectives: To understand the challenges and benefits of an extensive consultation process relating to the establishment and ongoing funding of a novel, disseminated national research network for infectious disease preparedness.

Methods: We used a two-part modified Delphi process to identify and rank factors relating to the consultation process across the different stages of setting up a new research network.

Results: Research priorities for the new research network remained the same following consultation with a broad range of stakeholders.

Decision-Making Strategies in Hospital Administrators in the Implementation of Nurse Residency Programs.

Current literature supports the creation and implementation of nurse residency programs to support new graduate nurses. The lack of this important postlicensure resource poses a problem for new graduate nurses who are seeking additional assistance and guidance during the transition to professional practice. This qualitative study revealed the factors, barriers, and benefits that influenced the decision-making process of nurse leaders in the implementation of nurse residency programs.

Characteristics, Comorbidities, and Data Gaps for Coronavirus Disease Deaths, Tennessee, USA.

As of March 2021, coronavirus disease (COVID-19) had led to >500,000 deaths in the United States, and the state of Tennessee had the fifth highest number of cases per capita. We reviewed the Tennessee Department of Health COVID-19 surveillance and chart-abstraction data during March 15‒August 15, 2020. Patients who died from COVID-19 were more likely to be older, male, and Black and to have underlying conditions (hereafter comorbidities) than case-patients who survived.

Time for revolution? Enhancing meaningful involvement of people living with HIV and affected communities in HIV cure-focused science.

Introduction: Involving affected communities and people living with HIV (PLHIV) in HIV cure-focused clinical trials has ethical and practical benefits. However, there can be barriers to meaningful involvement of 'lay people' in scientific research meaning community consultation is often limited or tokenistic. This paper reports on an Australian project, the INSPIRE project (mprove, urture and trengthen education, collaboration, and communication between LHV and searchers), which aimed to explore barriers and enablers to enactment of the principles of meaningful involvement of PLHIV (MIPA) and affected communities in HIV cure-focused research.

Acceptability, motivation and the prospect of cure for people living with HIV and their healthcare providers in HIV cure-focused treatment interruption studies.

Background: Analytical treatment interruptions (ATI) are commonly used clinical endpoints to assess interventions aimed at curing HIV or achieving antiretroviral therapy (ART)-free HIV remission. Understanding the acceptability of ATI amongst people living with HIV (PLHIV) and their HIV healthcare providers (HHP) is limited.

Methods: Two online surveys for PLHIV and HHP assessed awareness and acceptability of ATI, and understanding of the prospect for HIV cure in the future.

Changes in physical activity, diet, and body weight across the education and employment transitions of early adulthood: A systematic review and meta-analysis.

Early adulthood is a time when individuals go through important life transitions, such as moving from high school into higher education or employment, but the impact of these life transitions on changes in body weight, diet, and physical activity is not known. We searched six electronic databases to July 2019 for longitudinal observational studies providing data on adiposity, diet, and/or physical activity across education or employment transitions in young people aged between 15 and 35 years. We found 19 studies, of which 17 assessed changes in physical activity, three body weight, and five diet or eating behaviours.

Perspectives on Analytical Treatment Interruptions in People Living with HIV and Their Health Care Providers in the Landscape of HIV Cure-Focused Studies.

Analytical treatment interruptions (ATIs) aim to assess effects of HIV cure-focused interventions, but poses potential risks. Understanding of ATI acceptability among people living with HIV (PLHIV) and their HIV health care providers (HHP) is limited. Two international online surveys for PLHIV and HHP assessed understanding and acceptability of monitoring strategies during ATI.

Clinical trials of antiretroviral treatment interruption in HIV-infected individuals.

: Despite the benefits of antiretroviral therapy (ART) for people living with HIV, there has been a long-standing research interest in interrupting ART as a strategy to minimize adverse effects of ART as well as to test interventions aiming to achieve a degree of virological control without ART. We performed a systematic review of HIV clinical studies involving treatment interruption from 2000 to 2017 to describe the differences between treatment interruption in studies that contained and didn't contain an intervention. We assessed differences in monitoring strategies, threshold to restart ART, duration and adverse outcomes of treatment interruption, and factors aimed at minimizing transmission.

Versatility of Prolyl Oligopeptidase B in Peptide Macrocyclization.

Cyclic peptides are promising compounds for new chemical biological tools and therapeutics due to their structural diversity, resistance to proteases, and membrane permeability. Amatoxins, the toxic principles of poisonous mushrooms, are biosynthesized on ribosomes as 35mer precursor peptides, which are ultimately converted to hydroxylated bicyclic octapeptides. The initial cyclization steps, catalyzed by a dedicated prolyl oligopeptidase (POPB), involves removal of the 10-amino acid leader sequence from the precursor peptide and transpeptidation to produce a monocyclic octapeptide intermediate.

Persistence of integrated HIV DNA in CXCR3 + CCR6 + memory CD4+ T cells in HIV-infected individuals on antiretroviral therapy.

Background: HIV latent infection can be established in vitro by treating resting CD4 T cells with chemokines that bind to chemokine receptors (CKR), CCR7, CXCR3, and CCR6, highly expressed on T cells.

Objective: To determine if CKR identify CD4 T cells enriched for HIV in HIV-infected individuals receiving suppressive antiretroviral therapy (ART).

Design: A cross-sectional study of CKR expression and HIV persistence in blood from HIV-infected individuals on suppressive ART for more than 3 years (n = 48).

Activation of HIV transcription with short-course vorinostat in HIV-infected patients on suppressive antiretroviral therapy.

Unlabelled: Human immunodeficiency virus (HIV) persistence in latently infected resting memory CD4+ T-cells is the major barrier to HIV cure. Cellular histone deacetylases (HDACs) are important in maintaining HIV latency and histone deacetylase inhibitors (HDACi) may reverse latency by activating HIV transcription from latently infected CD4+ T-cells. We performed a single arm, open label, proof-of-concept study in which vorinostat, a pan-HDACi, was administered 400 mg orally once daily for 14 days to 20 HIV-infected individuals on suppressive antiretroviral therapy (ART).
