Development and implementation of take-home naloxone kit for patients admitted to the emergency department of a large tertiary care hospital

Title: Development and implementation of take-home naloxone kit for patients admitted to the emergency department of a large tertiary care hospital Authors: Myung Seon (Amy) Song, PharmD; Pamela Levine, PharmD, BCPS; Katharine F. Marshall, MD; Chelsea Harmon, PharmD Candidate 2020 Background/Purpose: In 2017, the United States Department of Health and Human Services (HHS) declared the opioid epidemic as a public health emergency as more than 70,000 people died from drug overdoses. Approximately 75% percent of unintentional opioid-overdose deaths occurred outside of a medical setting. In order to combat the opioid crisis, the US Surgeon General urged prescribers and pharmacists to increase access to naloxone for individuals who are at risk for opioid overdose. Community overdose education and naloxone distribution (OEND) programs have demonstrated that take-home naloxone kits are associated with reduced opioid-overdose death rates and are cost-effective. From January 2016 – June 2019, about 4,016 emergency department (ED) and urgent care visits in the Portland metropolitan area were identified to be due to opioid overdose. Recent data from the Centers for Disease Control and Prevention (CDC) indicates a continuing upward trend, making the ED a critical intervention point for providers and pharmacists to engage patients with at-risk of opioid overdose and provide evidence-based interventions such as take-home naloxone kit. The primary objective of this study is to develop and implement a pharmacist driven take-home naloxone kit protocol. The secondary objective is to increase access to naloxone by prescribing and dispensing kits to at-risk patients in the emergency department. Methods: A retrospective quasi-experimental, pre- and post-protocol analysis, will be used to compare the number of prescriptions written prior to implementation of protocol (April 1, 2017 to September 1, 2019) to the number of take-home naloxone kit dispensed post implementation of the protocol. Inclusion criteria include patients 18 years or older and admitted to ED for treatment of opioid overdose, or with risk factors of opioid overdose. The primary endpoint is number of naloxone prescription written and take-home naloxone kits dispensed. Results: Key stakeholders were identified and engaged in developing the protocol. Operational and cost consideration were reviewed. Various factors affected development and implementation of the study. Conclusions: Adaptation of parts of the study to take place in two large tertiary care hospitals. IRB status: Pendinghttps://digitalcommons.psjhealth.org/pharmacy_PGY1/1011/thumbnail.jp

Shock ion acceleration by an ultrashort circularly polarized laser pulse via relativistic transparency in an exploded target

We investigated ion acceleration by an electrostatic shock in an exploded target irradiated by an ultrashort, circularly polarized laser pulse by means of one- and three-dimensional particle-in-cell simulations. We discovered that the laser field penetrating via relativistic transparency (RT) rapidly heated the upstream electron plasma to enable the formation of a high-speed electrostatic shock. Owing to the RT-based rapid heating and the fast compression of the initial density spike by a circularly polarized pulse, a new regime of the shock ion acceleration driven by an ultrashort (20-40 fs), moderately intense (1-1.4 PW) laser pulse is envisaged. This regime enables more efficient shock ion acceleration under a limited total pulse energy than a linearly polarized pulse with crystal laser systems of lambda similar to 1 mu mopen

HIV-Specific Cellular Immune Responses Are Stimulated by Structured Treatment Interruption in Chronically HIV-1 Infected Koreans

We evaluated the enhancing effect of structured treatment interruptions (STIs) on HIV-specific immunity in chronically HIV-1 infected Korean patients. A prospective case-control study was done with a total of 10 subjects for a period of 26 weeks. Six subjects were on STIs and four subjects were on continuous HAART for comparison. The STI subjects underwent four periods of STIs. For those on STIs, HAART was stopped at week 0 for two weeks, and resumed thereafter for six weeks. Viral load and CD4+/CD8+ T cells were measured by HIV RNA RT-PCR and flow cytometry, and HIV-specific immunity was measured by an ELISPOT assay. HIV-specific cytotoxic T cell immunity was more pronounced in the STI subjects than in the continuous HAART subjects after 26 weeks (p = 0.011). The difference in cytotoxic T cell response in the STI group was more prominent than in the continuous HAART group (p = 0.011). Viral load after 26 weeks was higher in the STI subjects than in the continuous HAART subjects (p = 0.008). An HIV-specific cellular immune response can be stimulated by STIs in chronically HIV-infected Koreans. A larger study is warranted in order to further characterize viral and immunological parameters of treatment with STIs in cases of chronic HIV infection

Comparison of Efficacy of Cefoperazone/Sulbactam and Imipenem/Cilastatin for Treatment of Acinetobacter Bacteremia

Multiple antibiotic reisistance threatens successful treatment of Acinetobacter baumannii infections worldwide. Increasing interest in the well-known activity of sulbactam against the genus Acinetobacter has been aroused. The purpose of this study was to compare the outcomes for patients with Acinetobacter bacteremia treated with cefoperazone/sulbactam versus imipenem/cilastatin. Forty-seven patients with Acinetobacter baumannii bacteremia were analyzed through a retrospective review of their medical records for antibiotic therapy and clinical outcome. Thirty-five patients were treated with cefoperazone/sulbactam, and twelve patients with imipenem/cilastatin. The percentage of favorable response after 72 hours was not statistically different between cefoperazone/ sulbactam group and imipenem/ cilastatin group. The mortality rate was not statistically different, too. Cefoperazone/sulbactam was found to be as useful as imipenem/cilastatin for treating patients with Acinetobacter bacteremia

Lack of Toll-like Receptor 4 and 2 Polymorphisms in Korean Patients with Bacteremia

Toll-like receptors (TLRs) are pattern-recognition receptors that are important in innate immune responses to bacterial infection. The purpose of this study is to describe the prevalence of TLRs genetic variations in the bacteremic patients in Korea. A total of 154 patients with bacteremia and 179 healthy volunteers were included. The Asp299Gly and Thr399Ile allele of the TLR4 gene and Arg753Gln and Arg677Trp allele of the TLR2 gene were tested by PCR-RFLP. The DNA sequences were determined to confirm the PCR-RFLP results. Contrary to the expectation, no genetic polymorphisms were detected in both groups of this study, suggesting that it is very rare in Korean

Does Glycine max leaves or Garcinia Cambogia promote weight-loss or lower plasma cholesterol in overweight individuals: a randomized control trial

<p>Abstract</p> <p>Background</p> <p>Natural food supplements with high flavonoid content are often claimed to promote weight-loss and lower plasma cholesterol in animal studies, but human studies have been more equivocal. The aim of this study was firstly to determine the effectiveness of natural food supplements containing <it>Glycine max </it>leaves extract (EGML) or <it>Garcinia cambogia </it>extract (GCE) to promote weight-loss and lower plasma cholesterol. Secondly to examine whether these supplements have any beneficial effect on lipid, adipocytokine or antioxidant profiles.</p> <p>Methods</p> <p>Eighty-six overweight subjects (Male:Female = 46:40, age: 20~50 yr, BMI > 23 < 29) were randomly assigned to three groups and administered tablets containing EGML (2 g/day), GCE (2 g/day) or placebo (starch, 2 g/day) for 10 weeks. At baseline and after 10 weeks, body composition, plasma cholesterol and diet were assessed. Blood analysis was also conducted to examine plasma lipoproteins, triglycerides, adipocytokines and antioxidants.</p> <p>Results</p> <p>EGML and GCE supplementation failed to promote weight-loss or any clinically significant change in %body fat. The EGML group had lower total cholesterol after 10 weeks compared to the placebo group (p < 0.05). EGML and GCE had no effect on triglycerides, non-HDL-C, adipocytokines or antioxidants when compared to placebo supplementation. However, HDL-C was higher in the EGML group (p < 0.001) after 10 weeks compared to the placebo group.</p> <p>Conclusions</p> <p>Ten weeks of EGML or GCE supplementation did not promote weight-loss or lower total cholesterol in overweight individuals consuming their habitual diet. Although, EGML did increase plasma HDL-C levels which is associated with a lower risk of atherosclerosis.</p

NESH Regulates Dendritic Spine Morphology and Synapse Formation

Background: Dendritic spines are small membranous protrusions on the neuronal dendrites that receive synaptic input from axon terminals. Despite their importance for integrating the enormous information flow in the brain, the molecular mechanisms regulating spine morphogenesis are not well understood. NESH/Abi-3 is a member of the Abl interactor (Abi) protein family, and its overexpression is known to reduce cell motility and tumor metastasis. NESH is prominently expressed in the brain, but its function there remains unknown. Methodology/Principal Findings: NESH was strongly expressed in the hippocampus and moderately expressed in the cerebral cortex, cerebellum and striatum, where it co-localized with the postsynaptic proteins PSD95, SPIN90 and F-actin in dendritic spines. Overexpression of NESH reduced numbers of mushroom-type spines and synapse density but increased thin, filopodia-like spines and had no effect on spine density. siRNA knockdown of NESH also reduced mushroom spine numbers and inhibited synapse formation but it increased spine density. The N-terminal region of NESH co-sedimented with filamentous actin (F-actin), which is an essential component of dendritic spines, suggesting this interaction is important for the maturation of dendritic spines. Conclusions/Significance: NESH is a novel F-actin binding protein that likely plays important roles in the regulation o

How to Revitalize the Abdominal Ultrasonography Education Program

Abdominal ultrasound examinations are performed by many gastroenterologists in clinical practice, but abdominal ultrasound education has not been included in internal medicine resident or gastroenterology fellowship training courses. Abdominal ultrasound education was established as an essential part of the resident training program in 2017, and since then interest in ultrasound has increased. An educational accreditation system for trainers of ultrasonography in the internal medicine field was developed in 2018, but accredited ultrasound trainers and equipment and space for ultrasound education are lacking. This article describes how to revitalize ultrasound education program for resident and fellowship training

Zinc Oxide Nanoparticles Induce Autophagy and Apoptosis via Oxidative Injury and Pro-Inflammatory Cytokines in Primary Astrocyte Cultures

The present study examined the potential toxic concentrations of zinc oxide nanoparticles (ZnO NPs) and associated autophagy and apoptosis-related injuries in primary neocortical astrocyte cultures. Concentrations of ZnO NPs &ge;3 &mu;g/mL induced significant toxicity in the astrocytes. At 24 h after exposure to the ZnO NPs, transmission electron microscopy revealed swelling of the endoplasmic reticulum (ER) and increased numbers of autophagolysosomes in the cultured astrocytes, and increased levels of LC3 (microtubule-associated protein 1 light chain 3)-mediated autophagy were identified by flow cytometry. Apoptosis induced by ZnO NP exposure was confirmed by the elevation of caspase-3/7 activity and 4&prime;,6&prime;-diamidino-2-phenylindole (DAPI) staining. Significant (p &lt; 0.05) changes in the levels of glutathione peroxidase, superoxide dismutase, tumor necrosis factor (TNF-&alpha;), and interleukin-6 were observed by enzyme-linked immunoassay (ELISA) assay following the exposure of astrocyte cultures to ZnO NPs. Phosphatidylinositol 3-kinase (PI3K)/mitogen-activated protein kinase (MAPK) dual activation was induced by ZnO NPs in a dose-dependent manner. Additionally, the Akt (protein kinase B) inhibitor BML257 and the mTOR (mammalian target of rapamycin) inhibitor rapamycin contributed to the survival of astrocytes. Inhibitors of cyclooxygenase-2 and lipoxygenase attenuated ZnO NP-induced toxicity. Calcium-modulating compounds, antioxidants, and zinc/iron chelators also decreased ZnO NP-induced toxicity. Together, these results suggest that ZnO NP-induced autophagy and apoptosis may be associated with oxidative stress and the inflammatory process in primary astrocyte cultures
