Viral diversity and co-evolutionary dynamics across the ant phylogeny.

Knowledge of viral biodiversity within insects, particularly within ants, is extremely limited with only a few environmental viruses from invasive ant species identified to date. This study documents and explores the viral communities in ants. We comprehensively profile the metagenomes of a phylogenetically broad group of 35 ant species with varied ecological traits and report the discovery of 3710 novel and unique ant-associated viral genomes.

Treatment patterns and long-term survival outcomes for patients with stage III non-small cell lung cancer: A retrospective study.

Aim: Lung cancer is the leading cause of cancer-related deaths in Australia with poor long-term survival outcomes. Stage III non-small cell lung cancer (NSCLC) is a highly heterogenous group with diverse tumor characteristics and multiple, possible treatment options. We present retrospective data on patient characteristics, treatment patterns, and long-term outcomes in stage III NSCLC patients treated at a single cancer center in New South Wales, Australia.

OREX-1038: a potential new treatment for pain with low abuse liability and limited adverse effects.

Drugs targeting mu opioid receptors are the mainstay of clinical practice for treating moderate-to-severe pain. While they can offer excellent analgesia, their use can be limited by adverse effects, including constipation, respiratory depression, tolerance, and abuse liability. Multifunctional ligands acting at mu opioid and nociceptin/orphanin FQ peptide receptors might provide antinociception with substantially improved adverse-effect profiles.

Frailty and stroke thrombectomy outcomes-an observational cohort study.

Introduction: Mechanical thrombectomy (MT) can improve outcomes following ischaemic stroke. Patient selection for MT is predominantly based on physiological and imaging parameters. We assessed whether people living with pre-stroke frailty had differing outcomes following MT.

Localization of bacterial communities within gut compartments across turtle ants.

Microbial communities within the animal digestive tract often provide important functions for their hosts. The composition of eukaryotes' gut bacteria can be shaped by host diet, vertical bacterial transmission, and physiological variation within the digestive tract. In several ant taxa, recent findings have demonstrated that nitrogen provisioning by symbiotic bacteria makes up for deficiencies in herbivorous diets.

A comparison of the cuticular properties of argasid and ixodid ticks: Ornithodoros moubata (Argasidae) vs. Amblyomma hebraeum and Ixodes pacificus (Ixodidae).

Ticks (Chelicerata, Ixodida) are blood-feeding ectoparasites believed to have evolved at least about 120 millions of years ago and found worldwide. However, many aspects of their unique life cycle and anatomy, including their mechanical properties, remain to be understood. Here, we compared the mechanical properties of the cuticle of the argasid tick Ornithodoros moubata to those of two species of ixodid tick, Amblyomma hebraeum and Ixodes pacificus that we explored in our earlier studies of the tick exoskeleton.

The cost of providing mechanical thrombectomy in the UK NHS: a micro-costing study.

Introduction: The clinical efficacy and cost-effectiveness of mechanical thrombectomy (MT) for the treatment of large vessel occlusion stroke is well established, but uncertainty remains around the true cost of delivering this treatment within the NHS. The aim of this study was to establish the cost of providing MT within the hyperacute phase of care and to explore differences in resources used and costs across different neuroscience centres in the UK.

Method: This was a multicentre retrospective study using micro-costing methods to enable a precise assessment of the costs of MT from an NHS perspective.

OREX-1019: A Novel Treatment of Opioid Use Disorder and Relapse Prevention.

There is an urgent need for new pharmacological treatments for substance use disorders, including opioid use disorder, particularly for use in relapse prevention. A combination of buprenorphine with naltrexone has shown particular promise, with clinical studies indicating a substantial improvement over treatment with naltrexone alone. OREX-1019 (formerly BU10119) is a compound that mimics the pharmacology of the buprenorphine/naltrexone combination.

Structural Elucidation of Bisulfite Adducts to Pseudouridine That Result in Deletion Signatures during Reverse Transcription of RNA.

The recent report of RBS-Seq to map simultaneously the epitranscriptomic modifications -methyladenosine, 5-methylcytosine, and pseudouridine () via bisulfite treatment of RNA provides a key advance to locate these important modifications. The locations of were found by a deletion signature generated during cDNA synthesis after bisulfite treatment for which the chemical details of the reaction are poorly understood. In the present work, the bisulfite reaction with was explored to identify six isomers of bisulfite adducted to .

Outcomes after Thrombectomy in Belfast: Mothership and Drip-and-Ship in the Real World.

Background: Mechanical thrombectomy has revolutionised the treatment of acute ischaemic stroke due to large vessel occlusion. It is well recognised that patients are more likely to benefit when reperfusion happens quickly, however, there is uncertainty as to how best to deliver this service.

Objectives: To compare outcomes of patients in Northern -Ireland who underwent thrombectomy via direct admission to the single endovascular centre (mothership [MS]) with those transferred from primary stroke centres (drip-and-ship [DS]).

Assessing the Diversity of Endogenous Viruses Throughout Ant Genomes.

Endogenous viral elements (EVEs) can play a significant role in the evolution of their hosts and have been identified in animals, plants, and fungi. Additionally, EVEs potentially provide an important snapshot of the evolutionary frequency of viral infection. The purpose of this study is to take a comparative host-centered approach to EVE discovery in ant genomes to better understand the relationship of EVEs to their ant hosts.

Reintervention and Survival After Limited Lung Resection for Lung Cancer Treatment in Australia.

Background: To investigate the risk and predictors of reintervention (surgery or radiotherapy) after limited resection for lung cancer.

Methods: A population-based, all-inclusive study using linked data from the New South Wales Admitted Patient Data Collection and Death Register included all patients undergoing limited resection for lung cancer between July 1, 2002, and March 31, 2014. Univariate and adjusted competing risk analyses were used to estimate the effect of potential factors for risk of reintervention within 6 months and 24 months of the initial surgery.

Microphysiologic Human Tissue Constructs Reproduce Autologous Age-Specific BCG and HBV Primary Immunization .

Current vaccine development disregards human immune ontogeny, relying on animal models to select vaccine candidates targeting human infants, who are at greatest risk of infection worldwide, and receive the largest number of vaccines. To help accelerate and de-risk development of early-life effective immunization, we engineered a human age-specific microphysiologic vascular-interstitial interphase, suitable for pre-clinical modeling of distinct age-targeted immunity . Our Tissue Constructs (TCs) enable autonomous extravasation of monocytes that undergo rapid self-directed differentiation into migratory Dendritic Cells (DCs) in response to adjuvants and licensed vaccines such as Bacille Calmette-Guérin (BCG) or Hepatitis B virus Vaccine (HBV).

Increasing FIM2/3 antigen-content improves efficacy of Bordetella pertussis vaccines in mice in vivo without altering vaccine-induced human reactogenicity biomarkers in vitro.

Current acellular-pertussis (aP) vaccines appear inadequate for long-term pertussis control because of short-lived efficacy and the increasing prevalence of pertactin-negative isolates which may negatively impact vaccine efficacy. In this study, we added fimbriae (FIM)2 and FIM3 protein to licensed 2-, 3- or 5-component aP vaccines (Pentavac®, Boostrix®, Adacel®, respectively) to assess whether an aP vaccine with enhanced FIM content demonstrates enhanced efficacy. Vaccine-induced protection was assessed in an intranasal mouse challenge model.

A comparison of the cuticular properties of the female ticks Ixodes pacificus and Amblyomma hebraeum (Acari: Ixodidae) throughout the feeding period.

The mechanical properties of the cuticle of Ixodes pacificus (Ip) are compared to those of Amblyomma hebraeum (Ah) from our earlier work. The 10-fold size difference between the species is expected to lead to significant differences in mechanical properties, because cuticular stretch depends on high internal hydrostatic pressure during the rapid phase of engorgement. We demonstrate here: (1) The cuticle of partially fed Ip is less stiff and viscous than that of Ah.

Tracheobronchial stents in palliative care: a case series and literature review.

Objective: To evaluate the outcomes of tracheobronchial stenting in patients with malignant central airway obstruction and assist practitioners in palliative settings in understanding the indications, contraindications and management of tracheobronchial stents.

Methods: This retrospective study involved a consecutive case series of palliative patients with central airway obstruction secondary to inoperable cancers who underwent tracheobronchial stenting at a single institution. The European Cooperative Oncology Group (ECOG) scale was used to evaluate patient functional status before and after tracheobronchial stenting.

Insights into Circovirus Host Range from the Genomic Fossil Record.

A diverse range of DNA sequences derived from circoviruses (family ) has been identified in samples obtained from humans and domestic animals, often in association with pathological conditions. In the majority of cases, however, little is known about the natural biology of the viruses from which these sequences are derived. Endogenous circoviral elements (CVe) are DNA sequences derived from circoviruses that occur in animal genomes and provide a useful source of information about circovirus-host relationships.

The value of neuroimaging team meetings for patients in a district general hospital.

Neuroradiologists provide quality-assured neuroimaging -reports. We developed the use of a neuroimaging team meeting to provide second-opinion reporting by neuroradiologists on neuroimaging that had previously been reported by general -radiologists. Neuroimaging from selected patients was reviewed at the meeting.

Consensus minimum data set for lung cancer multidisciplinary teams: Results of a Delphi process.

Background And Objective: While multidisciplinary team (MDT) care in lung cancer is widely practiced, there are few guidelines for MDT on best data collection strategies. MDT meetings need ready access to information for the provision of optimal treatment recommendations (the primary purpose of the meeting), audit of team performance and benchmarking. This study aimed to develop a practical data set designed for these goals through a recognized consensus process with health professionals who participate in formal MDT settings.

ESCAPE to Reality, Post-Trial Outcomes in an ESCAPE Centre: A Retrospective Case-Control Study.

Introduction: The Royal Victoria Hospital, Belfast provides the regional neuroendovascular service for Northern Ireland and was an enrolling centre for the ESCAPE endovascular stroke trial. Our aim was to assess outcomes for patients presenting with acute stroke following discontinuation of trial enrolment at our centre.

Methods: We collected data on all patients presenting with acute stoke between Nov-1st-2014 and Oct-31st-2015 who received endovascular treatment or received IV thrombolysis (IV-tPA) alone.
