046) which represented a 17% relative difference. LOS was longer on HD5 (p = 0.013) and when a CT scan was ordered (p less then 0.001). Conclusion No difference was found in the rate at which the PIT ordered CT scans on high volume vs low volume days. The rate of CT scans without clinically relevant findings did increase slightly on high volume days. LOS was longer on high volume days and when a CT was ordered.Background Patients who present with atrial fibrillation (AF) or flutter with rapid ventricular response (RVR) and hemodynamic stability may be managed with either an intravenous (IV) nondihydropyridine calcium channel blocker (CCB) or a beta-blocker (BB). Patients without improved heart rates may need to switch to, or add, a second AV nodal blocker. Objective To evaluate the incidence of rate control achievement and bradycardia in patients in AF or atrial flutter with RVR who receive both an intravenous CCB and a BB. Methods A retrospective chart review of patients who received concomitant intravenous CCB or BB for the treatment of rapid AF or atrial flutter from April 2016 through July 2018 in the emergency department. Patients were excluded if the second agent was ordered but not administered, or if they received IV amiodarone or digoxin. Results A total of 136 patients were included in the analysis, and of those, 46% (n = 62) of patients achieved a heart rate less then 110 bpm without bradycardia, and 3.7% (n = 5) developed bradycardia. Age, initial heart rate, time between CCB and BB administration, addition of an oral CCB or BB administration, or administration of IV magnesium did not impact target heart rate achievement. Conclusion Adding a second nodal blocker in patients who did not achieve rate control with the first agent resulted in heart rate control 46% of the time. The development of symptomatic bradycardia was uncommon.Background Tocilizumab, a humanized monoclonal antibody, targets IL-6 receptors blocking downstream pro-inflammatory effects of IL-6. In preliminary reports it was suggested to be beneficial in patients with severe COVID-19. Methods In this open-label prospective study we describe clinical characteristics and outcome of 51 patients hospitalized with confirmed and severe COVID-19 pneumonia treated with tocilizumab intravenously. All patients had elevated IL-6 plasma level (>40 pg/mL) and oxygen saturation less then 93% in ambient air. Clinical outcomes, oxygen support, laboratory data and adverse events were collected over a follow-up of 30 days. Results Forty-five patients (88%) were on high-flow oxygen supplementation, six of whom with invasive ventilation. From baseline to day 7 after tocilizumab we observed a dramatic drop of body temperature and CRP value with a significant increase in lymphocyte count (p less then 0.001). Over a median follow-up time of 34 days from tocilizumab, 34 patients (67%) showed an improvement in their clinical severity class; 31 were discharged; 17 (33%) showed a worsening of their clinical status, of these 14 died (27%). The mortality rate was significantly associated with mechanical ventilation at baseline (83.3% vs 20% of patients on non-invasive oxygen support; p=0.0001). The most frequent side effects were an increase of hepatic enzymes (29%), thrombocytopenia (14%), and serious bacterial and fungal infections (27%). Conclusion Tocilizumab exerts a rapidly beneficial effect on fever and inflammatory markers, although no significant impact on the clinical outcome can be inferred by our results. Critically ill patients seem to have a high risk of serious infections with this drug.Background Research trials testing the impact of community pharmacy services require adequate and appropriate recruitment of patients by participating pharmacists, however, this step presents an ongoing challenge. Objective To identify factors affecting recruitment of patients in community pharmacies participating in a multi-center trial of a pharmacy asthma service in Australia (Pharmacy Trial Program - Asthma and Rhinitis Control (PTP-ARC). Methods The PTP-ARC protocol required identification and recruitment of seven eligible asthma patients per pharmacy. Pharmacists responsible for sites that failed to recruit or retain any patients into the PTP-ARC trial participated in a semi-structured telephone interview about their experiences with these elements of the trial. The interviews were recorded, transcribed and coded using QSR International's NVivo 11 software. The analysis was conducted with reference to the COM-B framework (Capability, Opportunity, Motivation). Results Pharmacists from 47 of 50 eligible pce-based trials towards practice implementation, user-friendly software, pharmacists' training on research and patient-engagement and adequate remuneration to address pharmacist time issues need to be key foci for health services design and implementation research.Objectives This study explored intrinsic facilitators (i.e., grit, self-efficacy, and writing motivation) and barriers associated with scholarly output as measured by self-reported publications among US pharmacy practice faculty. Methods A cross-sectional study design was used to gather information regarding scholarly writing output and intrinsic facilitators and barriers among US pharmacy practice faculty using an online self-reported survey. The survey link was distributed via email between October and November 2017. The Grit-S, New Generalized Self-Efficacy Scale (NGSE), and Scholarly Writing Motivation Scale (SWMS) were used to measure grit, self-efficacy, and writing motivation, respectively. Perceived barriers, self-reported quantity of publications, and demographics were also collected. A structural equation modeling (SEM) approach was used to determine effects of perceived barriers and each intrinsic factor on self-reported total publications. Results N = 208 participants were included in the analysesolleges/schools of pharmacy to enhance scholarly activities among pharmacy practice faculty.Purpose To investigate the current patterns of diagnosis and referral in keratoconus. Methods A retrospective chart review was performed of patients who had recently been diagnosed with keratoconus and attended dedicated clinics at Antwerp University Hospital, Belgium and Maria Middelares General Hospital, Ghent, Belgium between June 2013 and February 2018. Exclusion criteria included longstanding keratoconus diagnosis, reduced cognitive capabilities and prior surgical procedures (corneal crosslinking, penetrating keratoplasty or any type of refractive surgery). Results Three-hundred and ninety-nine patients (722 eyes) were included in this study. The mean age was 24.7 ± 6.5 years and the average maximal keratometry was 51 ± 5.2 D for the better eye and 58.4 ± 9.6 D for the worse eye. Upon diagnosis, 233 eyes (32.2 %) and 51 eyes (7.1 %) had a thinnest pachymetry less then 450 and less then 400 μm, respectively. At 6-month follow-up, 58 % of patients had been fitted with specialty contact lenses. During follow-up, 199 eyes (27.6 %) underwent corneal crosslinking. One patient underwent corneal graft surgery of his worse eye due to contact lens intolerance and insufficient visual acuity. selleck products Conclusion Despite advances in diagnostic tools, keratoconus is often diagnosed at a relatively late stage. Earlier detection of keratoconus would increase the overall clinical benefit of corneal crosslinking. Further research into screening strategies is required to develop cost-effective screening programs.Klebsiella pneumoniae has an exceptional ability to acquire exogenous resistance-encoding and hypervirulence-encoding genetic elements. In this review we trace the key evolutionary routes of plasmids involved in the dissemination of such elements; we observed diverse, but convergent, evolutionary paths that eventually led to the emergence of conjugative plasmids which simultaneously encode carbapenem resistance and hypervirulence. One important evolutionary feature of these plasmids is that they contain a wide range of transposable elements that enable them to undergo frequent genetic transposition, resulting in plasmid fusion and presumably better adaptation of the plasmid to the bacterial host. Identifying the key molecular markers of resistance and virulence-bearing conjugative plasmids allows improved tracking and control of the life-threatening carbapenem-resistant and hypervirulent strains of K. pneumoniae.There has been an explosion of metagenomic data representing human, animal, and environmental microbiomes. This provides an unprecedented opportunity for comparative and longitudinal studies of many functional aspects of the microbiome that go beyond taxonomic classification, such as profiling genetic determinants of antimicrobial resistance, interactions with the host, potentially clinically relevant functions, and the role of mobile genetic elements (MGEs). One of the most important but least studied of these aspects are the MGEs, collectively referred to as the 'mobilome'. Here we elaborate on the benefits and limitations of using different metagenomic protocols, discuss the relative merits of various sequencing technologies, and highlight relevant bioinformatics tools and pipelines to predict the presence of MGEs and their microbial hosts.Cytomegalovirus (CMV) infection elicits a potent immune response that includes the stimulation of antibodies with neutralizing activity. Recent studies have focused on elucidating the role of neutralizing antibodies in protecting against CMV infection and disease and characterizing viral antigens against which neutralizing antibodies are directed. Here, we provide a synthesis of recent data regarding the role of neutralizing antibodies in protection against CMV infection/disease. We consider the role of humoral immunity in the context of the global CMV-specific immune response, and the implications that recent findings have for vaccine and antibody-based therapy design.The COVID-19 pandemic commands a major reorganisation of the entire French healthcare system. In France, general rules have been issued nationally and implemented by each healthcare centre, both public and private, throughout France. Guidelines drafted by an expert group led by the French-speaking Association of Endocrine Surgery (AFCE) propose specific surgical management principles for thyroid, parathyroid, endocrine pancreas and adrenal surgery during and after the COVID-19 epidemic.Optical coherence tomography is a catheter-based imaging modality in heart catheterizations, which provides a significantly higher resolution of intravascular pathology by means of using light as opposed to ultrasound. The applications of this modality may include a detailed assessment of atherosclerotic plaques, stent evaluation including coverage and restenosis and percutaneous coronary intervention optimization. In this article, we provide a review of current literature highlighting the advantages and disadvantages of the use of optical coherence tomography in the catheterization lab.The 2019 coronavirus disease is a serious public health emergency, with serious adverse implications for populations, healthcare systems, and economies globally. Recently, concerns have been raised about possible association between ethnicity, incidence and outcomes of COVID-19 arisen from early government data. In this review, we will explore the possible association using both recent COVID-19 studies and studies of previous pandemics. We call for data on ethnicity to be routinely collected by governments, as part of an international collaboration, alongside other patient demographics and further research to robustly determine the magnitude of association. Moreover, governments must learn from previous pandemics and recommended strategies to mitigate risks on minority ethnicities due to socioeconomic disadvantages.
