Determination of emergency nurse practitioner and plastic surgery trainee disposition decision agreement for plastic surgery emergency department presentations: A prospective study.

OBJECTIVE: To examine if there was a high degree of agreement for disposition decisions of emergency nurse practitioners (ENP) compared to plastic surgery trainees (PST) for plastic surgery presentations. METHODS: A prospective study of disposition decision agreement from February 2020 to January 2021 for patients who required plastic surgery consultation and managed exclusively by an ENP. Absolute percentages were used to determine the exact disposition decision accuracy of ENP and the PST, while Cohen's kappa compared disposition decision agreement. Sub-analyses of age, gender, ENP experience and presenting condition agreement were also completed. To mitigate confounding factors, operative management (OM) and non-OM groups were analysed. RESULTS: The study recruited 342 patients who presented mostly with finger or hand-related conditions (82%, n = 279) and managed by an ENP with less than 10 years of experience (65%, n = 224). Disposition decisions by ENP compared to PST were the same in 80% (n = 274) of cases. Disposition agreement for all patients was 0.72 (95% confidence interval 0.66-0.78). For the OM and non-OM groups, disposition decisions were the same in 94% (n = 320), with a Cohen's kappa 0.85 (95% confidence interval 0.79-0.91). Seven patients (2%) were discharged to GP care by the ENP when determined to need further plastic surgery involvement by the PST. CONCLUSIONS: Disposition decisions by ENP and PST were the same in most cases and had a high overall level of agreement. This may lead to greater autonomy of ENP care and reduced ED length of stay and occupancy.

Intentional paediatric poisoning presentations to emergency departments during the COVID-19 pandemic.

OBJECTIVE: To characterise paediatric poisoning presentations to EDs and determine if the advent of the COVID-19 pandemic was associated with increased intentional paediatric poisoning presentations. METHODS: We performed a retrospective analysis of paediatric poisoning presentations to three EDs (two regional and one metropolitan). Simple and multiple logistic regression analysis were performed to determine the association between COVID-19 and intentional poisoning events. In addition, we calculated the frequency with which patients reported various psychosocial risk factors as being an implicating factor in engaging in an intentional poisoning event. RESULTS: A total of 860 poisoning events met inclusion criteria during the study period (January 2018-October 2021), with 501 being intentional, and 359 unintentional. There was an increased proportion of intentional poisoning presentations during the COVID-19 pandemic (261 intentional and 218 unintentional in the pre-COVID-19 period vs 241 intentional and 140 unintentional during the COVID-19 period). In addition, we found a statistically significant association between intentional poisoning presentations and an initial COVID-19 lockdown (adjusted odds ratio 26.32, P < 0.05). 'The COVID-19 lockdown' or 'COVID-19' was reported to be implicating factor for psychological stress in patients who presented with intentional poisonings during the COVID-19 pandemic. CONCLUSIONS: Intentional paediatric poisoning presentations increased during the COVID-19 pandemic in our study population. These results may support an emerging body of evidence that the psychological strain of COVID-19 disproportionately impacts adolescent females.

Toxicology presentations to a tertiary unit in New South Wales during the COVID-19 pandemic first wave: A retrospective comparison study.

OBJECTIVE: To compare presentation numbers, class of exposure, poison severity score (PSS) and drugs ingested by patients in a tertiary toxicology service during the first wave of the COVID-19 pandemic to the corresponding time periods in 2018 and 2019. METHODS: A retrospective cohort observational study of patients admitted or consulted to the Western Sydney Toxicology Service (WSTS) from ED during February to May in 2018-2020. Patient age, sex, triage category, time and date of arrival, mode of arrival, type of poisoning, discharge location, length of stay and PSS were collected from WSTS database and electronic medical records. The total number of ED presentations, hospital admissions and toxicology admissions were gathered from hospital-based data services. RESULTS: There was an overall increase in toxicology presentations in February to May 2020 (n = 441) compared to 2019 (n = 333) and 2018 (n = 255). The daily rate of presentations increased in March to May 2020 with an overall rate ratio of 1.42, 95% confidence interval 1.23-1.63, P < 0.001. There was an increase in presentations across all drug types. From March to April 2020, there was significantly higher number of daily presentations for recreational drugs use compared to 2018. CONCLUSION: There was a relative increase in toxicology presentations during the COVID-19 pandemic compared to an overall decrease in presentations to ED. Recreational drug use increased significantly during the pandemic compared to 2018.

Utility of non-contrast head computed tomography in poisoned patients.

OBJECTIVE: To investigate the utility of non-contrast head computed tomography (CT) in poisoned patients. METHODS: A retrospective cohort study of patients referred to a toxicology unit between August 2010 and December 2017. Our database yielded patients who underwent head CT at presentation to the ED. Pre-specified information was compiled from the medical records. RESULTS: There were 6261 presentations of which 1142 underwent head CT (17%). Median age was 41 years, and 437 (38%) were female. There were 492 (43%) recreational ingestions and 466 (41%) deliberate self-poisonings. The commonest agents were sedatives 376 (33%) and opioids 282 (24%); 334 (29%) cases were intubated. Signs of head injury were found in 153 cases (13%) and focal neurological signs in 68 (6%). No acute pathology was reported in 884 head CTs (77%), chronic changes in 193 (17%) and incidental findings in 26 (2%). Acute pathology was found in 39 (4%) patients: 15 with hypoxic-ischaemic injury, three infarctions, nine with intra-cranial haemorrhage, 11 facial bone fractures and one retro-bulbar haematoma. No patient required an immediate surgical intervention, and only one patient had a change to clinical treatment. Acute head CT pathology was associated with at least one of the following clinical features: need for intubation, signs of head injury, seizure, headache, and unexpected neurological signs. CONCLUSION: Non-contrast head CT is a low-yield investigation in patients presenting with poisoning. Consideration should be given as to whether the clinical presentation is consistent with the expected toxidrome and whether the patient would benefit from head CT.

Innovative Approaches to Improve Public Health Practice in the Eastern Mediterranean Region: Findings From the Sixth Eastern Mediterranean Public Health Network Regional Conference.

Public health professionals in the Eastern Mediterranean region (EMR) have limited access to continuing education, including workshops and conferences in public health. Held under the theme Innovative Approaches: Adapting to the Current EMR Context, the Eastern Mediterranean Public Health Network (EMPHNET) organized and conducted the Sixth EMPHNET Regional Conference from March 26 to 29, 2018. This paper summarizes the key activities including workshops, roundtable discussions, oral and poster presentations, keynote speeches, and side meetings. Before the opening, 5 preconference workshops were held: "Field Epidemiology Training Program (FETP) Accreditation," "Innovative Public Health Surveillance," "Human and Animal Brucellosis," "Rapid Response Teams," and "Polio Transition and Routine Immunization." The conference hosted 6 roundtable discussions: "Consolidation of the FETP Network," "One Health to Achieve Global Health Security," "Polio Eradication Efforts and Transition Planning for Measles Elimination," "Mobile Data Collection and Other Innovative Tools to Enhance Decision Making," "Confronting Candida auris: An Emerging Multidrug-resistant Global Pathogen," and "Functioning and Sustainable Country Public Health Emergency Response Operation Framework." One of the conference's key objectives was to provide a space for FETP residents, graduates, and public health professionals to showcase achievements. A total of 421 abstracts were submitted and after professional review, 34.9% (147/421) were accepted (111 for oral presentations and 36 for poster presentations) and published by Iproceeding. The conference met the primary objectives of showcasing the public health accomplishments and contributions of the EMR, encouraging the exchange of ideas and coordination among stakeholders, and engaging cross-sectoral workforce in producing recommendations for approaching regional and global health concerns. Moreover, the conference presented a unique opportunity for FETPs and other public health professionals from the Mediterranean region to present their significant scientific work and also facilitated networking among professionals. EMPHNET strives to continue to present similar exchange opportunities for public health professionals in the region.

Myocardial Injury from Tranylcypromine-Induced Hypertensive Crisis Secondary to Excessive Tyramine Intake.

Monoamine oxidase inhibitors (MAOIs) are known to cause hypertensive crisis when combined with intake of tyramine, classically found in cheese. We present a case of MAOI-induced hypertensive crisis leading to significant troponin release after soft cheese intake. A 51-year-old lady presented with left-sided chest pain, palpitations and headache in the context of significant hypertension after eating soft cheese. She had a similar episode 2 month prior to this presentation, which resulted in a diagnosis of non-ST elevation myocardial infarction after a troponin of 2768 ng/L (Ref < 17 ng/L) with normal cardiac investigations and CT pulmonary angiogram. She was known to be on tranylcypromine for bipolar depression. Subsequent cardiac investigations were normal, as were those for phaeochromocytoma and Conn's disease. Tranylcypromine is a non-selective irreversible MAOI used in refractory depression and bipolar disorder. MAOIs are known to cause hypertensive crisis when combined with soft cheese due to unopposed release of catecholamines from reduced tyramine metabolisation, leading to injury and possible myonecrosis. Three previous case reports have demonstrated either creatinine kinase or troponin rise with myocardial infarction due to this hypertensive crisis and our case is the fourth with significant hypertension and cardiac biomarker rise related to MAOI, specifically tranylcypromine.

A North/South collaboration between two national public health institutes--a model for global health protection.

Rapid international spread of emerging infections has increased interest in strategic collaborations, as they may be the best way to protect populations. Strategic collaborations can build capacity in less-resourced settings. As specialised institutions that provide a stable locus of expertise, continuity of experience, scientific knowledge, and appropriate human, technical, and financial resources, national public health institutes (NPHIs) are well-prepared to tackle public health challenges. We describe how a collaboration between the NPHIs of England and South Africa built a mutually beneficial professional relationship to help implement the WHO International Health Regulations, build capacity for health protection, and promote the exchange of information, advice, and expertise. We illustrate how this can be achieved in a mutually beneficial way.

Achieving compliance with the International Health Regulations by overseas territories of the United Kingdom of Great Britain and Northern Ireland.

The 2005 International Health Regulations (IHR) came into force for all Member States of the World Health Organization (WHO) in June 2007 and the deadline for achieving compliance was June 2012. The purpose of the IHR is to prevent, protect against, control - and provide a public health response to - international spread of disease. The territory of the United Kingdom of Great Britain and Northern Ireland and that of several other Member States, such as China, Denmark, France, the Netherlands and the United States of America, include overseas territories, which cover a total population of approximately 15 million people. Member States have a responsibility to ensure that all parts of their territory comply with the IHR. Since WHO has not provided specific guidance on compliance in the special circumstances of the overseas territories of Member States, compliance by these territories is an issue for self-assessment by Member States themselves. To date, no reports have been published on the assessment of IHR compliance in countries with overseas territories. We describe a gap analysis done in the United Kingdom to assess IHR compliance of its overseas territories. The findings and conclusions are broadly applicable to other countries with overseas territories which may have yet to assess their compliance with the IHR. Such assessments are needed to ensure compliance across all parts of a Member States' territory and to increase global health security.

Le Règlement sanitaire international de 2005 (RSI) est entré en vigueur pour tous les États membres de l'Organisation mondiale de la Santé en juin 2007, et la date limite pour sa mise en conformité était juin 2012. L'objectif du RSI est de prévenir, de protéger, de contrôler ­ et d'apporter une réponse de santé publique ­ à la propagation internationale des maladies. Le territoire du Royaume-Uni de Grande-Bretagne et d'Irlande du Nord et celui d'autres États membres, comme la Chine, le Danemark, la France, les Pays-Bas et les États-Unis d'Amérique, se composent de territoires d'outre-mer, lesquels couvrent une population totale d'environ 15 millions d'habitants. Les États membres ont la responsabilité de veiller à ce que toutes les parties de leur territoire se conforment au RSI. Étant donné que l'OMS ne fournit pas d'orientation spécifique concernant la conformité dans les circonstances spéciales des territoires d'outre-mer des États membres, leur conformité est une question d'auto-évaluation par les États membres eux-mêmes. À ce jour, aucun rapport n'a été publié sur l'évaluation de la conformité au RSI dans les pays possédant des territoires d'outre-mer. Nous décrivons une analyse des lacunes effectuée au Royaume-Uni pour évaluer la conformité au RSI de ses territoires d'outre-mer. Les résultats et les conclusions sont largement applicables aux autres pays possédant des territoires d'outre-mer, qui peuvent cependant évaluer leur propre conformité au RSI. Ces évaluations sont nécessaires pour veiller à la conformité dans toutes les parties du territoire d'un État membre et pour augmenter la sécurité sanitaire mondiale.

El Reglamento Sanitario Internacional 2005 (RSI) entró en vigor para todos los Estados miembros de la Organización Mundial de la Salud (OMS) en junio de 2007 con junio de 2012 como fecha límite para lograr el cumplimiento. El objetivo del RSI es prevenir, proteger, controlar y proporcionar una respuesta de salud pública a la propagación internacional de enfermedades. El territorio del Reino Unido de Gran Bretaña e Irlanda del Norte y otros Estados miembros como China, Dinamarca, Francia, los Países Bajos y los Estados Unidos de América cuentan con territorios de ultramar que abarcan una población total de aproximadamente 15 millones de personas. Los Estados miembros tienen la responsabilidad de garantizar que todos sus territorios cumplan con el RSI. Puesto que la OMS no ha proporcionado orientación específica sobre el cumplimiento para las circunstancias especiales de los territorios de ultramar de los Estados miembros, el cumplimiento por parte de estos territorios es un problema que los propios Estados miembros tienen que evaluar. Hasta la fecha no se han publicado informes sobre la evaluación del cumplimiento del RSI en los países con territorios de ultramar. Describimos un análisis de las deficiencias realizado en el Reino Unido con objeto de evaluar el cumplimiento del RSI de sus territorios de ultramar. Los resultados y conclusiones son ampliamente aplicables a otros países con territorios de ultramar que quizá aún tengan que evaluar su cumplimiento con el RSI. Dichas evaluaciones son necesarias para asegurar el cumplimiento en todos los territorios de los Estados miembros y para aumentar la seguridad sanitaria mundial.

Establishing an enteric bacteria reference laboratory in Sierra Leone.

In 2012, Sierra Leone experienced its worst cholera outbreak in over 15 years affecting 12 of the country's 13 districts. With limited diagnostic capability, particularly in bacterial culture, the cholera outbreak was initially confirmed by microbiological testing of clinical specimens outside of Sierra Leone. During 2012 - 2013, in direct response to the lack of diagnostic microbiology facilities, and to assist in investigating and monitoring the cholera outbreak, diagnostic and reference services were established in Sierra Leone at the Central Public Health Reference Laboratory focusing specifically on isolating and identifying Vibrio cholerae and other enteric bacterial pathogens. Sierra Leone is now capable of confirming cholera cases by reference laboratory testing.

Ibuprofen-Induced Hypokalemia and Distal Renal Tubular Acidosis: A Patient's Perceptions of Over-the-Counter Medications and Their Adverse Effects.

We highlight a case of distal renal tubular acidosis secondary to ibuprofen and codeine use. Of particular interest in this case are the patient's perception of over-the-counter (OTC) medication use, her own OTC use prior to admission, and her knowledge of adverse reactions or side effects of these medications prior to taking them.

Bench-to-bedside review: the value of cardiac biomarkers in the intensive care patient.

The use of cardiac biomarkers in the intensive care setting is gaining increasing popularity. There are several reasons for this increase: there is now the facility for point-of-care biomarker measurement providing a rapid diagnosis; biomarkers can be used as prognostic tools; biomarkers can be used to guide therapy; and, compared with other methods such as echocardiography, the assays are easier and much more affordable. Two important characteristics of the ideal biomarker are disease specificity and a linear relationship between the serum concentration and disease severity. These characteristics are not present, however, in the majority of biomarkers for cardiac dysfunction currently available. Those clinically useful cardiac biomarkers, which naturally received the most attention, such as troponins and B-type natriuretic peptide, are not as specific as was originally thought. In the intensive care setting, it is important for the user to understand the degree of specificity of these biomarkers and that the interpretation of the results should always be guided by other clinical information. The present review summarizes the available biomarkers for different cardiac conditions. Potential biomarkers under evaluation are also briefly discussed.

Pharmacological properties of the enhanced-affinity glucocorticoid fluticasone furoate in vitro and in an in vivo model of respiratory inflammatory disease.

Fluticasone furoate (FF) is a novel enhanced-affinity glucocorticoid that has been developed as topical therapy for allergic rhinitis. The pharmacological properties of FF have been investigated using a number of in vitro experimental systems. FF demonstrated very potent glucocorticoid activity in several key pathways downstream of the glucocorticoid receptor (GR) as follows: the transrepression nuclear factor-kappaB (NF-kappaB) pathway, the transactivation glucocorticoid response element pathway, and inhibition of the proinflammatory cytokine tumor necrosis factor-alpha. Furthermore, FF showed the greatest potency compared with other glucocorticoids for preserving epithelial integrity and reducing epithelial permeability in response to protease- and mechanical-induced cell damage. FF showed a 30- to >330,000-fold selectivity for GR-mediated inhibition of NF-kappaB vs. the other steroid hormone receptors, substantially better than a number of other clinically used glucocorticoids. In studies examining the respiratory tissue binding properties of glucocorticoids, FF had the largest cellular accumulation and slowest rate of efflux compared with other clinically used glucocorticoids, consistent with greater tissue retention. The in vivo anti-inflammatory activity of FF was assessed in the Brown Norway rat ovalbumin-induced lung eosinophilial model of allergic lung inflammation. At a dose of only 30 microg, FF achieved almost total inhibition of eosinophil influx in the lung, an inhibition that was greater than that seen with the same dose of fluticasone propionate. In conclusion, the potent and selective pharmacological profile of FF described here could deliver an effective, safe, and sustained topical treatment of respiratory inflammatory diseases such as allergic rhinitis and asthma.
