Analysis of the yearly transition function in measles disease modeling

Globally, there were an estimated 9.8 million measles cases and 207 500 measles deaths in 2019. As the effort to eliminate measles around the world continues, modeling remains a valuable tool for public health decision-makers and program implementers. This study presents a novel approach to the use of a yearly transition function that formulates mathematically the vaccine schedules for different age groups while accounting for the effects of the age of vaccination, the timing of vaccination, and disease seasonality on the yearly number of measles cases in a country. The methodology presented adds to an existing modeling framework and expands its analysis, making its utilization more adjustable for the user and contributing to its conceptual clarity. This article also adjusts for the temporal interaction between vaccination and exposure to disease, applying adjustments to estimated yearly counts of cases and the number of vaccines administered that increase population immunity. These new model features provide the ability to forecast and compare the effects of different vaccination timing scenarios and seasonality of transmission on the expected disease incidence. Although the work presented is applied to the example of measles, it has potential relevance to modeling other vaccine-preventable diseases.

Understanding the factors influencing community pharmacist retention - A qualitative study

Background

Shortages in healthcare workers affects the overall delivery and effectiveness of the provision of healthcare. There are currently insufficient pharmacists working in the community sector in Ireland. While several studies have reported on the factors leading to retention in the medical and nursing profession, there is an absence of robust research examining retention within the pharmacist workforce in Ireland.

Objective

To identify and understand the range of factors currently at play in the community pharmacy sector in Ireland which influence the decision-making process for pharmacists deciding whether or not to continue to practice as a community pharmacist.

Method

A cross-sectional qualitative descriptive study was used to investigate the factors influencing community pharmacist retention as elicited from the lived experiences of 23 pharmacists. Study recruitment was undertaken using both convenience and purposive sampling. Qualitative content analysis was used to analyze the interview data to identify and explore themes.

Results

A broad and diverse range of factors were identified as affecting community pharmacist retention including working conditions, career fulfilment and progression, regulatory and administrative burden, the commercial focus within community practice, lack of representation and their overall health and well-being.

Conclusion

The findings show that there are a number of factors which either individually or cumulatively influence a pharmacist's decision to stay in or leave community practice. Various areas for change were identified, which if addressed are considered likely to improve retention in the sector. These include enhanced terms and working conditions, better acknowledgement and resourcing of professional activities, improved opportunities for career progression, reforms to the regulatory model including the personal accountability of a supervising pharmacist for all of the pharmacy's professional activities, a more streamlined model of reimbursement and more effective collective representation.

Studies on the novel effects of electron beam treated pollen on colony reproductive output in commercially-reared bumblebees (Bombus terrestris) for mass pollination applications

Commercially-reared bumblebees provide an important pollinator service that helps support food production and security. The deployment of an appropriate non-thermal disinfection technology for the bulk treatment of pollen collected from honeybees for the feeding of commercial bumblebees is important in order to mitigate against complex diseases and unwanted pathogen spillover to native bees. High level disinfection of pollen was achieved using an electron (e)-beam dose of 100 kGy that corresponded to 78 % loss of cellular viability of bee pathogens before feeding to bumblebees as measured by the novel in vitro use of flow cytometry (FCM). Novel findings showed that e-beam treated-pollen that was fed to bumblebees produced fewer females, gynes and exhibited an absence of males when compared to control bumblebee colonies that were fed untreated commercial pollen. A similar trend emerged in bumblebee colony reproductive outputs when using membrane filtered washed pollen. Proteomic analysis of bumblebees from individual colonies fed with treated-pollen revealed a differential abundance of proteins associated with stress, immunity and metabolism when compared to the untreated pollen control group. Microbiome analysis of the bumblebee gut content revealed differences in microbiota between treated and untreated pollen in bumblebee colony studies. This novel study evaluated the impact of industrial e-beam treated-pollen on complex bee disease mitigation where physically treated-pollen fed to bumblebees was shown to substantially affect colony reproductive outputs.

Palliative care for persons with late-stage Alzheimer's and related dementias and their caregivers: protocol for a randomized clinical trial

BACKGROUND

Limited access to specialized palliative care exposes persons with late-stage Alzheimer's disease and related dementias (ADRD) to burdensome treatment and unnecessary hospitalization and their caregivers to avoidable strain and financial burden. Addressing this unmet need, the purpose of this study was to conduct a randomized clinical trial (RCT) of the ADRD-Palliative Care (ADRD-PC) program.

METHODS

The study will use a multisite, RCT design and will be set in five geographically diverse US hospitals. Lead investigators and outcome assessors will be masked. The study will use 1:1 randomization of patient-caregiver dyads, and sites will enroll N = 424 dyads of hospitalized patients with late-stage ADRD with their family caregivers. Intervention dyads will receive the ADRD-PC program of (1) dementia-specific palliative care, (2) standardized caregiver education, and (3) transitional care. Control dyads will receive publicly available educational material on dementia caregiving. Outcomes will be measured at 30 days (interim) and 60 days post-discharge. The primary outcome will be 60-day hospital transfers, defined as visits to an emergency department or hospitalization ascertained from health record reviews and caregiver interviews (aim 1). Secondary patient-centered outcomes, ascertained from 30- and 60-day health record reviews and caregiver telephone interviews, will be symptom treatment, symptom control, use of community palliative care or hospice, and new nursing home transitions (aim 2). Secondary caregiver-centered outcomes will be communication about prognosis and goals of care, shared decision-making about hospitalization and other treatments, and caregiver distress (aim 3). Analyses will use intention-to-treat, and pre-specified exploratory analyses will examine the effects of sex as a biologic variable and the GDS stage.

DISCUSSION

The study results will determine the efficacy of an intervention that addresses the extraordinary public health impact of late-stage ADRD and suffering due to symptom distress, burdensome treatments, and caregiver strain. While many caregivers prioritize comfort in late-stage ADRD, shared decision-making is rare. Hospitalization creates an opportunity for dementia-specific palliative care, and the study findings will inform care redesign to advance comprehensive dementia-specific palliative care plus transitional care.

Evolution of a minimal cell

Possessing only essential genes, a minimal cell can reveal mechanisms and processes that are critical for the persistence and stability of life1,2. Here we report on how an engineered minimal cell3,4 contends with the forces of evolution compared with the Mycoplasma mycoides non-minimal cell from which it was synthetically derived. Mutation rates were the highest among all reported bacteria, but were not affected by genome minimization. Genome streamlining was costly, leading to a decrease in fitness of greater than 50%, but this deficit was regained during 2,000 generations of evolution. Despite selection acting on distinct genetic targets, increases in the maximum growth rate of the synthetic cells were comparable. Moreover, when performance was assessed by relative fitness, the minimal cell evolved 39% faster than the non-minimal cell. The only apparent constraint involved the evolution of cell size. The size of the non-minimal cell increased by 80%, whereas the minimal cell remained the same. This pattern reflected epistatic effects of mutations in ftsZ, which encodes a tubulin-homologue protein that regulates cell division and morphology5,6. Our findings demonstrate that natural selection can rapidly increase the fitness of one of the simplest autonomously growing organisms. Understanding how species with small genomes overcome evolutionary challenges provides critical insights into the persistence of host-associated endosymbionts, the stability of streamlined chassis for biotechnology and the targeted refinement of synthetically engineered cells2,7-9.

Clinical seizure semiology is subtle and identification of seizures by parents is unreliable in infants with tuberous sclerosis complex

OBJECTIVE

The objectives of this study were to assess the accuracy of parental seizure detection in infants with antenatally diagnosed tuberous sclerosis complex (TSC), and to document the total seizure burden (clinical and subclinical) in those patients who met criteria for prolonged electroencephalography (EEG) recording.

METHODS

Consecutive infants at a single institution with antenatally diagnosed TSC who met criteria for prolonged video-EEG (vEEG) were recruited to this study. The vEEG data were reviewed and when a seizure was identified on EEG, the video and audio recording was assessed for evidence of clinical seizure and, if present, whether there was evidence of parent seizure identification.

RESULTS

Nine infants were enrolled, for whom 674 focal seizures were identified in eight of nine patients across 24 prolonged vEEG recordings, with vEEG total duration of 634 h 49 min (average seizure frequency of 1 focal seizure/h). Only 220 of 674 (32.6%) were clinical seizures, 395 of 674 (58.6%) were subclinical seizures, and 59 of 674 seizures could not be classified. Only 63 of 220 clinical seizures (28.6%) were identified by parents, with 157 of 220 (71.4%) not identified. Thirty clusters of epileptic spasms were detected in one patient. At least one clinical epileptic spasm occurred in 2 of 30 clusters (6.7%), 24 of 30 clusters of epileptic spasms (80%) were electrographic only, and classification was uncertain for 4 of 30 clusters (13.3%). No clinical epileptic spasms were detected by parents. Clinical seizure frequency was significantly underestimated by parents for all patients.

SIGNIFICANCE

This study demonstrates that in infants with TSC who met criteria for prolonged vEEG, (1) parents significantly under recognize total clinical seizure count, (2) parents fail to identify epileptic spasms, and (3) seizure frequency is high. This highlights that epilepsy treatment decisions should not be based solely on parental clinical seizure identification. Prolonged vEEG monitoring may have an important role in the routine epilepsy care of infants with TSC, as demonstrating undetected high clinical seizure frequency may allow improved epilepsy management decisions.

Exploring the feasibility of smartglass facilitated remote supervision in the emergency department: A simulation study

OBJECTIVE

Smartglasses are a wearable computer technology that has potential to facilitate remote supervision to junior doctors working in different clinical settings. The present study aimed to explore the feasibility of smartglass technology to enable remote supervision of junior clinicians by senior clinicians during emergency simulation scenarios.

METHODS

This was a feasibility simulation study using high-fidelity mannequins and standardised patients. Trainee interns (TIs) and supervising clinicians (SCs) were invited to participate in two scenarios: a trauma case and a stroke case. There was a pre-sim questionnaire. The TI wore the smartglasses in a simulated ED bay and performed patient assessment and management. Remote supervision was provided by the SC via a livestream on a remote computer. Upon completion, participants completed a survey regarding their experience comprising of Likert scale and free-text questions.

RESULTS

Fifteen TIs and 19 SCs participated. In general feedback from TIs and SCs was positive. TIs were able to identify and treat the key diagnostic problems set during the scenarios. Free-text survey responses provided specific feedback about what did and did not work when using the glasses.

CONCLUSION

The present study demonstrates that smartglasses facilitated remote assistance has promise as an emergent technology and warrants further investigation in simulated and non-simulated environments.

Cohort profile: the ESC EURObservational Research Programme Non-ST-segment elevation myocardial infraction (NSTEMI) Registry

AIMS

The European Society of Cardiology (ESC) EURObservational Research Programme (EORP) Non-ST-segment elevation myocardial infarction (NSTEMI) Registry aims to identify international patterns in NSTEMI management in clinical practice and outcomes against the 2015 ESC Guidelines for the management of acute coronary syndromes in patients presenting without ST-segment-elevation.

METHODS AND RESULTS

Consecutively hospitalised adult NSTEMI patients (n = 3620) were enrolled between 11 March 2019 and 6 March 2021, and individual patient data prospectively collected at 287 centres in 59 participating countries during a two-week enrolment period per centre. The registry collected data relating to baseline characteristics, major outcomes (in-hospital death, acute heart failure, cardiogenic shock, bleeding, stroke/transient ischaemic attack, and 30-day mortality) and guideline-recommended NSTEMI care interventions: electrocardiogram pre- or in-hospital, pre-hospitalization receipt of aspirin, echocardiography, coronary angiography, referral to cardiac rehabilitation, smoking cessation advice, dietary advice, and prescription on discharge of aspirin, P2Y12 inhibition, angiotensin converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB), beta-blocker, and statin.

CONCLUSION

The EORP NSTEMI Registry is an international, prospective registry of care and outcomes of patients treated for NSTEMI, which will provide unique insights into the contemporary management of hospitalised NSTEMI patients, compliance with ESC 2015 NSTEMI Guidelines, and identify potential barriers to optimal management of this common clinical presentation associated with significant morbidity and mortality.

Lethal hemorrhage from iliac vein rupture complicating inferior vena cava thrombosis demonstrated by post-mortem CT angiography

Spontaneous iliac vein rupture is a rare cause of retroperitoneal hemorrhage that may present to the forensic pathologist. It has been reported in association with venous thrombosis, anatomical variants such as May-Thurner syndrome, and as a complication of a long-term indwelling IVC filter. It has a female predominance and most often occurs due to rupture of the left iliac vein. This is the first report of the use of post-mortem computed tomography (PMCT) and post-mortem computed tomography angiography (PMCTA) as an adjunct to a conventional autopsy to diagnose rupture of the left iliac vein causing retroperitoneal hemorrhage arising as a complication of an inferior vena cava (IVC) thrombus. We discuss the use of PMCTA as a useful tool in the diagnosis of vascular injury and how it can be used to assist the forensic pathologist. The use of PMCT with PMCTA is an invaluable adjunct to conventional autopsy to diagnose the site of vascular rupture.

Bridging the gap between healthcare professions' regulation and practice: the "lived experience" of community pharmacists in Ireland following regulatory change

BACKGROUND

Reforms to models of health and care regulation internationally have adapted to address the challenges associated with regulating healthcare professionals. Pharmacists in Ireland entered a new era of regulation with the enactment of the Pharmacy Act in 2007 which significantly updated the law regulating pharmacy in Ireland and expanded the regulatory scope considerably. An earlier study in 2017 examined the experiences of 20 community pharmacists of the Act. This follow-up study aimed to expand the scope of the original study to all community pharmacists in Ireland, to report their "lived experience" of the regulatory model introduced by the Act, assessing its impact on their professional practice using the principles of "better regulation".

METHODS

Survey methodology was used to assess the perception of all community pharmacists registered with the Pharmaceutical Society of Ireland of the Act, as implemented, on their practice using an experimental design based on the seven principles of "Better Regulation". Descriptive statistics analyzed quantitative responses while answers from open-ended questions were analyzed using a combination of a modified framework analysis and a qualitative content analysis.

RESULTS

Respondents agreed that the Act was necessary, although its implementation by the regulator was largely not viewed as fulfilling the remaining "Better Regulation" principles of being effective, proportional, consistent, agile, accountable and transparent. In particular, its proportionality was questioned. This resulted in pharmacists perceiving that their professional competency to act in the best interests of their patients was not appropriately acknowledged by the regulator, which in turn compromised their ability to provide optimal care for their patients.

CONCLUSION

While healthcare professional regulation must primarily be concerned with public protection, it must also have regard to its impact on those delivering healthcare services. The findings highlight the challenge internationally of balancing rigidity and flexibility in professional health and care regulation, and the importance of a regulatory conversation occurring between those regulating and those regulated. This would serve to promote mutual learning and understanding to create a responsive approach to regulation, underpinned by mutual trust, effective risk assessment and adherence to the principles of "Better Regulation".

12 VACCINATION UP-TAKE IN DERMATOLOGY PATIENTS OVER THE AGE OF 65 YEARS ON BIOLOGICAL TREATMENT

Background

Biologic and immunosuppressive therapies play important roles in the management of a wide variety of dermatologic diseases. However, immunotherapies can negatively affect normal immune functioning, placing these patients at high risk of infection. The strength of the immune system also declines with increasing age. Thus, in accordance with the British Association of Dermatology guidelines (August 2021), patients taking biologic therapy can and should have their covid, influenza and pneumococcal vaccinations.

Methods

We conducted a retrospective audit of all patients over the age of 65 years on biological therapy in the dermatology clinic between March 2021 to March 2022. Data on patients covid, influenza and pneumococcal vaccination status was obtained from Dermatology database and patients medical records.

Results

A total of 18 patients over the age of 65 years, were on biological therapy in the Dermatology Department, between March 2021 to March 2022. The mean age was found to be 71 years with a standard deviation of 5.2 and there was equal gender distribution. 94% (n=17) of patients had psoriasis and 6% (n=1) had eczema. With regards to biological treatments, 17% (n=3) of patients were on Adalimumab,11% (n=2) on Etanercept and 28% (n=5) on Cosntyx. 100% (n=18) had all three of their covid-19 vaccines. 50% (n=8) are awaiting their 4th covid vaccination. 94% (n=17) of patients had their influenza vaccine. 66% (n=12) had their pneumococcal vaccination, the patients who had not had their pneumococcal vaccination were recommended and advised to have it.

Conclusion

This audit confirms dermatology patients over the age of sixty-five years, are compliant on receiving their covid vaccinations, as recommended by the BAD. However, only 66% of patients had their pneumococcal vaccination and 94% had their influenza vaccine, illustrating the need for educational intervention on the importance of vaccination. This will then be followed by a reaudit next year to complete the audit cycle.

SARS-CoV-2 Testing and Patient Waiting Times in the Emergency Department

Aim Emergency Departments (EDs) were impacted early in the coronavirus disease 2019 (COVID-19) pandemic, with high attendance numbers. EDs relied upon SARS-CoV-2 reverse-transcriptase polymerase chain reaction (RT-PCR) tests to triage patients and facilitate admission to appropriate wards, meaning positive patients were isolated as early as possible. In October 2020, we introduced a 24-hour SARS-CoV-2 testing service. We examined the impact of this on patient experience times (PETs) in the ED, and on healthcare-associated (HA) COVID-19 infections. Methods Data on PETs before and after the introduction of 24-hour testing were available from the ED. HA COVID-19 infections were reported weekly to the Health Services Executive as a key performance indicator. Results Mean PET prior to the pandemic was 20 hours and dropped to 10 and 13 hours respectively in the first and second wave. A surge in case numbers and ED attendances during the third wave was not reflected in a rise in PETs, with a mean PET of 11 hours, significantly below pre-pandemic levels. HA-COVID-19 infections remained stable between wave one and three (83 v 92). Conclusion The introduction of 24-hour SARS-CoV-2 testing in our ED contributed to a reduction in PETs, facilitated appropriate patient placement at ward level, and kept HA-COVID-19 infections at acceptably low levels.

Heterozygous NOTCH1 variants cause CNS immune activation and microangiopathy

NOTCH1 belongs to the NOTCH family of proteins that regulate cell fate and inflammatory responses. Somatic and germline NOTCH1 variants have been implicated in cancer, Adams-Oliver syndrome and cardiovascular defects. We describe seven unrelated patients grouped by the presence of leukoencephalopathy with calcifications and heterozygous de novo gain-of-function variants in NOTCH1. Immunologic profiling showed upregulated CSF IP-10, a cytokine secreted downstream of NOTCH1 signaling. Autopsy revealed extensive leukoencephalopathy and microangiopathy with vascular calcifications. This evidence implicates that heterozygous gain-of-function variants in NOTCH1 lead to a chronic CNS inflammatory response resulting in a calcifying microangiopathy with leukoencephalopathy.

Intracoronary IgG4-related disease as an unusual cause of sudden cardiac arrest: a case series

Background

IgG4-related disease (IgG4-RD) is a fibro-inflammatory condition classically causing retroperitoneal fibrosis, aortitis, thyroiditis, or pancreatitis. Diagnosis includes the presence of lymphoplasmacytic infiltrate (with >40% ratio IgG4+:IgG plasma cells) and fibrosis. Cardiac involvement may include aortic, pericardial, or coronary disease. Coronary manifestations encompass obstructive intra-luminal lesions, external encasing pseudo-tumour on imaging, or lymphoplasmacytic arteritis.

Case summary

Case 1: A fit and healthy 50-year-old man was found deceased. His only known medical condition was treated Hashimoto’s thyroiditis. Post-mortem examination demonstrated an isolated severe stenosis of the left anterior descending (LAD) coronary artery without histopathological evidence of acute myocardial infarction. Coronary plaque histopathology showed florid IgG4-positive plasma cell infiltrate throughout all layers of the artery with dense fibrous tissue connective tissue stroma, all features consistent with coronary artery IgG4-RD. Case 2: A 48-year-old man collapsed at work. Computed tomography scan 1 week prior reported an ill-defined para-aortic retroperitoneal soft tissue density. No cardiac symptoms were reported in life. Post-mortem examination showed coronary arteritis and peri-arteritis with sclerosing peri-aortitis in the LAD. There was myocardial fibrosis of the anterior left ventricle and focal myocarditis of the right ventricle.

Discussion

IgG4-related disease presenting as sudden cardiac death without any preceding symptoms is very rare (six prior cases identified on literature review). Reported targeted successful interventions for intracoronary IgG4-RD diagnosed in life have included steroid therapy and B cell depleting therapy (i.e. rituximab). If cardiac symptoms are present in a patient with known IgG4-RD, cardiac investigations should be promptly arranged.

Educating pharmacy students through a pandemic: Reflecting on our COVID-19 experience

The impact of the COVID-19 pandemic on pharmacy education worldwide has been immense, affecting students, educators and regulatory agencies. Pharmacy programmes have had to rapidly adapt in their delivery of education, maintaining standards while also ensuring the safety of all stakeholders. In this commentary, we describe the challenges, compromises and solutions adopted by our institution throughout the pandemic, the lessons learnt, adaptive measures taken, and strategies to develop and future-proof our curricula.

ANCA-Associated Vasculitis Following Pfizer-BioNTech COVID-19 Vaccine

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues to spread around the world. As of the end of June 2021, there were approximately 181 million confirmed cases and more than 3.9 million deaths across the globe. The colossal impact of coronavirus disease 2019 (COVID-19) is driving the biggest vaccination campaign in human history. All 3 vaccines authorized for emergency use by the US Food and Drug Administration (Pfizer-BioNTech, Moderna, and Janssen/Johnson & Johnson) have been thoroughly studied and found to be safe and effective in preventing severe COVID-19 cases. While short-term side effects of COVID-19 vaccine resemble those of other vaccines, long-term side effects remain unknown. Rare side effects continue to surface as millions of people receive COVID-19 vaccines around the world, as compared with the thousands enrolled in the clinical trials. We report a case of new-onset renal-limited ANCA-associated vasculitis (AAV) in a 78-year-old woman with previously normal kidney function after receiving the Pfizer-BioNTech COVID-19 vaccine. The patient developed acute kidney injury with proteinuria and microscopic hematuria with many dysmorphic red blood cells in the urine. Anti-myeloperoxidase antibody titer was elevated. Kidney biopsy showed pauci-immune crescentic necrotizing glomerulonephritis. Kidney function improved after treatment with steroids and rituximab. Our patient had normal routine laboratory testing before the vaccination. Although this case cannot demonstrate a causal relationship between COVID-19 vaccination and AAV, ongoing surveillance for similar complications would be prudent as worldwide vaccination efforts continue.

OP0259-HPR THE EFFECT OF OSTEOARTHRITIS ON HEALTHY WORKING LIFE EXPECTANCY AT AGE 50 IN ENGLAND

Background:

Retirement ages are rising in many countries due to population ageing and increasing life expectancy. However, poor health, comorbidity and workplace factors are major reasons for work absence and it is unclear if people in later working-age life (age ≥50) are able to work for longer. Osteoarthritis (OA), the most common joint condition in adults, is the fastest increasing major health condition globally and is a leading cause of disability (especially in adults age ≥50).

Objectives:

We aimed to estimate healthy working life expectancy (HWLE; defined as the average number of years that adults from age 50 can expect to be healthy and in paid work) for adults with and without osteoarthritis and investigate the role of mental health problems as a comorbidity and the role of workplace factors through examining whether there is a sense of having any control over what happens at work.

Methods:

Longitudinal survey data of adults aged ≥50 years were used from six waves (2002-2013) of the English Longitudinal Study of Ageing with linked mortality data from the National Health Service Central Register. HWLE was defined using two self-report variables; health was defined as no long-standing illness or no activity limitation if long-standing illness was present, and work was defined being in employment or self-employment. OA status was identified by self-report of ever receiving a diagnosis from a doctor. Mental health and control of work were measured by self-report. Continuous-time multistate models with three states (healthy and working [state 1], other alive [2], dead [3]) were fitted in R (version 3.6.1) to investigate factors driving transitions out of the healthy and working state. Models included age and combinations of sex, OA, control at work, and mental health problems. Age-adjusted hazards of transitions between states were estimated using the ‘msm’ R package. HWLE for adults with different factors (OA, control of work, mental health) was estimated with the ‘elect’ R package using models fitted with ‘msm’. Missing data was handled using multiple imputation by predictive mean matching.

Results:

There were 11,540 adults with at least two observations (including survey and mortality data) for the study period (5251 males, 6289 females). Life expectancy at age 50 was 29.7 years for men and 33.4 years for women with HWLE being 9.9 years (men) and 8.3 years (women). HWLE at age 50 for adults with osteoarthritis was 7.3 years (men: 8.2, women: 6.8), and for adults without osteoarthritis was higher at 9.9 years (men: 10.6, women: 9.1). After adjusting for age, the instantaneous risk of ceasing to be both healthy and in work (not due to death) for people with OA was 1.5 times that of people without OA (hazard rate ratio 1.5 with 95% CI [1.3, 1.6]). For adults without OA, HWLE at age 50 was 13.2 years if they felt they had control at work and 4.1 years without control at work, whilst for adults with OA, HWLE was 10.4 years if they felt they had control at work and 3.1 years without. The effect of mental health problems as a comorbidity on HWLE was smaller; for adults without OA, HWLE at age 50 was 11.0 years for those without mental health problems and 8.3 years for those with, whilst for adults with OA, HWLE was 8.6 years for those without mental health problems and 6.2 years with.

Conclusion:

While the average HWLE for men and women in England is lower than State Pension age, HWLE at age 50 is even lower (by approximately 25%) in adults with OA compared to adults without OA. Poor mental health further reduces HWLE. However, good quality work environments significantly lessen the impact of osteoarthritis (there is a 7.3 year difference in HWLE for those with OA who do and do not experience control at work). These results suggest that interventions and policies that create appropriate job opportunities and supportive workplaces for older workers with health conditions are key to the feasibility and success of extended working life policies.

Mitigation policies, community mobility, and COVID-19 case counts in Australia, Japan, Hong Kong, and Singapore

OBJECTIVES

The objective of the study was to characterize the timing and trends of select mitigation policies, changes in community mobility, and coronavirus disease 2019 (COVID-19) epidemiology in Australia, Japan, Hong Kong, and Singapore.

STUDY DESIGN

Prospective abstraction of publicly available mitigation policies obtained from media reports and government websites.

METHODS

Data analyzed include seven kinds of mitigation policies (mass gathering restrictions, international travel restrictions, passenger screening, traveler isolation/quarantine, school closures, business closures, and domestic movement restrictions) implemented between January 1 and April 26, 2020, changes in selected measures of community mobility assessed by Google Community Mobility Reports data, and COVID-19 epidemiology in Australia, Japan, Hong Kong, and Singapore.

RESULTS

During the study period, community mobility decreased in Australia, Japan, and Singapore; there was little change in Hong Kong. The largest declines in mobility were seen in places that enforced mitigation policies. Across settings, transit-associated mobility declined the most and workplace-associated mobility the least. Singapore experienced an increase in cases despite the presence of stay-at-home orders, as migrant workers living in dormitories faced challenges to safely quarantine.

CONCLUSIONS

Public policies may have different impacts on mobility and transmission of severe acute respiratory coronavirus-2 transmission. When enacting mitigation policies, decision makers should consider the possible impact of enforcement measures, the influence on transmission of factors other than movement restrictions, and the differential impact of mitigation policies on subpopulations.

Genome-wide surveillance of transcription errors in response to genotoxic stress

Mutagenic compounds are a potent source of human disease. By inducing genetic instability, they can accelerate the evolution of human cancers or lead to the development of genetically inherited diseases. Here, we show that in addition to genetic mutations, mutagens are also a powerful source of transcription errors. These errors arise in dividing and nondividing cells alike, affect every class of transcripts inside cells, and, in certain cases, greatly exceed the number of mutations that arise in the genome. In addition, we reveal the kinetics of transcription errors in response to mutagen exposure and find that DNA repair is required to mitigate transcriptional mutagenesis after exposure. Together, these observations have far-reaching consequences for our understanding of mutagenesis in human aging and disease, and suggest that the impact of DNA damage on human physiology has been greatly underestimated.

COVID-19 related regulatory change for pharmacists - The case for its retention post the pandemic

The delivery of healthcare including the provision of pharmacy services globally is highly regulated internationally in order to protect public health and welfare. However, the onset of the COVID-19 pandemic has precipitated the need internationally to amend the model of regulation in order to ensure that people were able to continue to access a range of healthcare services in a timely and effective manner. Many of the changes introduced to the regulation of pharmacy services in Ireland have been replicated in other countries. These include the introduction of electronic means to transmit prescriptions and other orders for medications, relaxing the legal restrictions in place controlling the emergency supply of prescription only medicines and more fully utilizing the professional competency of pharmacists by empowering them to use their expertise and judgment to support their patients accessing the healthcare services that they need. Many of the regulatory changes that have been introduced to support the COVID-19 public health emergency effort are ones that pharmacists have previously sought to enable them provide a more effective and expanded model of pharmaceutical care to their patients. Accordingly, many pharmacists will want these regulatory changes to be retained and further expanded in the aftermath of the COVID-19 public health emergency in order to extend their scope of practice and support them in the care of their patients.

Opportunities for the application of real-time bacterial cell analysis using flow cytometry for the advancement of sterilization microbiology

Medical devices provide critical care and diagnostic applications through patient contact. Sterility assurance level (SAL) may be defined as the probability of a single viable micro-organism occurring on an item after a sterilization process. Sterilization microbiology often relies upon using an overkill validation method where a 12-log reduction in recalcitrant bacterial endospore population occurs during the process that exploits conventional laboratory-based culture media for enumeration. This timely review explores key assumptions underpinning use of conventional culture-based methods in sterilization microbiology. Consideration is given to how such methods may limit the ability to fully appreciate the inactivation kinetics of a sterilization process such as vaporized hydrogen peroxide (VH2O2) sterilization, and consequently design efficient sterilization processes. Specific use of the real-time flow cytometry (FCM) is described by way of elucidating the practical relevance of these limitation factors with implications and opportunities for the sterilization industry discussed. Application of FCM to address these culture-based limitation factors will inform real-time kinetic inactivation modelling and unlock potential to embrace emerging opportunities for pharma, medical device and sterilization industries including potentially disruptive applications that may involve reduced usage of sterilant.

A retrospective review of pregnancies on biologics for the treatment of dermatological conditions

Psoriasis often first presents in young adulthood, with the average age of diagnosis in women being 28 years, thus in the prime reproductive years. In addition, approximately 50% of pregnancies worldwide are unplanned. Although biologic therapies have revolutionized the treatment of moderate-to-severe psoriasis, there are no controlled studies of biologics in pregnant women. The increasing use of these agents in women of childbearing age highlights the need to further assess their safety during pregnancy. Postmarketing experience regarding the safety of these drugs is accumulating and being published, with largely reassuring results. We present our real-world experience of 17 pregnancies occurring in women on treatment with biologic agents for dermatological conditions to further add to the body of knowledge.

Abstract TP412: Electroencephalographic Monitoring in Pediatric Arterial Ischemic Stroke

Introduction: Seizures occur at a high frequency in acute arterial ischemic stroke (AIS) in children however there is very limited knowledge regarding the frequency of electrographic only seizures. Early data suggests that seizures may independently be associated with a poorer outcome in acute brain injury. Without EEG monitoring electrographic seizures will go undetected resulting in a lost opportunity for neuroprotection. The aim of our study was to determine the incidence and risk factors of clinical and electrographic seizures in pediatric AIS.

Methods: A pilot prospective single center study was performed between July 2018 and July 2019. Patients between 1 month and 18 years of age were eligible. Video EEG monitoring commenced <10 days following stroke onset. A neurologist and a second independent blinded epileptologist reported the EEG’s. Assessments included the Pediatric National Institutes of Health Stroke Scale (PedNIHSS) score and the modified Alberta Stroke Program Early Computed Tomography Score (modASPECTS). Clinical management was at the discretion of the treating neurologist. A standardized follow-up assessment was performed at 3 months.

Results: Of 11 patients who had AIS during the study period, 10 were recruited. Median age was 3.7 years (range 6 weeks -12 years). Mean EEG duration was 26.8 hours. Electrographic seizures occurred in 4 (40%) patients. Of these 4 patients, 2 had clinical seizures prior to EEG onset. In addition, 1 patient had a clinical seizure prior to EEG with no subsequent electrographic seizures seen. Of the 5 patients with seizures, 3 were less than 2 years of age. Overall electrographic seizure burden was high. Only 2 of 10 patients had no cortical infarction however 1 of these patients had electrographic seizures. In comparing the group with electrographic seizures to those without, there was no statistically significant difference in the modASPECTS (median 4.5 (IQR 4) vs. 4 (9), p = 0.9239) and PedNIHSS scores (5 (9.5) vs. 14 (17), p = 0.3425).

Conclusion: This prospective study demonstrated a high frequency and burden of electrographic seizures in young children with AIS. A larger multi-center study is warranted to define risk factors and outcome determinants with potential for recommendation regarding interventions.

Willingness-to-pay for long-lasting insecticide-treated bed nets: a discrete choice experiment with real payment in Ghana

Background

Expanding access to long-lasting insecticidal nets (LLINs) is difficult if one is limited to government and donor financial resources. Private commercial markets could play a larger role in the continuous distribution of LLINs by offering differentiated LLINs to middle-class Ghanaians. This population segment has disposable income and may be willing to pay for LLINs that meet their preferences. Measuring the willingness-to-pay (WTP) for LLINs with specialty features that appeal to middle-class Ghanaians could help malaria control programmes understand what is the potential for private markets to work alongside fully subsidized LLIN distribution channels to assist in spreading this commodity.

Methods

This study conducted a discrete choice experiment (DCE) including a real payment choice among a representative sample of 628 middle-income households living in Ashanti, Greater Accra, and Western regions in Ghana. The DCE presented 18 paired combinations of LLIN features and various prices. Respondents indicated which LLIN of each pair they preferred and whether they would purchase it. To validate stated willingness-to-pay, each participant was given a cash payment of $14.30 (GHS 65) that they could either keep or immediately spend on one of the LLIN products.

Results

The households’ average probability of purchasing a LLIN with specialty features was 43.8% (S.D. 0.07) and WTP was $7.48 (GHS34.0). The preferred LLIN features were conical or rectangular one-point-hang shape, queen size, and zipper entry. The average WTP for a LLIN with all the preferred features was $18.48 (GHS 84). In a scenario with the private LLIN market, the public sector outlay could be reduced by 39% and private LLIN sales would generate $8.1 million ($311 per every 100 households) in revenue in the study area that would support jobs for Ghanaian retailers, distributors, and importers of LLINs.

Conclusion

Results support a scenario in which commercial markets for LLINs could play a significant role in improving access to LLINs for middle-income Ghanaians. Manufacturers interested could offer LLIN designs with features that are most highly valued among middle-income households in Ghana and maintain a retail price that could yield sufficient economic returns.

Who buys nets? Factors associated with ownership and use of purchased mosquito nets in sub-Saharan Africa

BACKGROUND

Public sector strategies to promote insecticide-treated net (ITN) access have resulted in increased ITN ownership across sub-Saharan Africa. However, the current status of the private sector distribution channel for nets has not been fully explored. This multi-country study explored the prevalence of net purchases and the characteristics of households that had purchased nets and used such nets in sub-Saharan Africa.

METHODS

Data from recent Malaria Indicator Survey (MIS) or Demographic and Health Survey (DHS) in 16 countries were analysed to explore the prevalence of purchased nets. Purchased nets were defined as nets obtained from shops/markets or pharmacies. Additional sub-analysis of factors associated with ownership and use of purchased nets was conducted in seven countries with over 10% of nets reported as purchased. Key outcomes included: prevalence of purchased nets out of all nets, household ownership of a purchased net, and whether a purchased net was used the previous night. Analytical methods included country level tests of association and multivariable logistic regressions.

RESULTS

Among all nets, the proportion of purchased nets in the study countries ranged from 0.8 to 32.7% and most (median = 77%) of these purchased nets were ITNs. Although the private nets are presumed to be from the retail, non-public sector, the prevalence of treated purchased nets suggests that some purchased nets may be "leaked" ITNs from public sector distributions, and thus, may be an informal sector rather than part of the formal "private sector". Urban, wealthier households as well as those with educated heads were more likely to own purchased nets. Use of such nets was, however, lower in wealthier households. In addition, net use was higher in households owning insufficient nets for their family size, and when the nets were newer than 24 months.

CONCLUSION

The formal and informal private sector have played a role in bolstering net access rates in some settings. Study findings can help relevant malaria control stakeholders gain insight on the contribution of purchased nets on their overall ITN strategy, identify potential target populations for private sector nets as well as inform the design and distribution of private sector insecticide-treated nets that appeal to their target groups.

Poverty and food security: drivers of insecticide-treated mosquito net misuse in Malawi

Background

Over the past decade, food insecurity, connected to erratic rains and reduced agricultural outputs, has plagued Malawi. Many households are turning to fishing to seek additional sources of income and food. There is anecdotal evidence that insecticide-treated net (ITN) recipients in Malawi are using their nets for purposes other than sleeping, such as for fishing, protecting crops, and displaying merchandise, among others. The objective of this qualitative study was to explore the factors leading residents of waterside communities in Malawi to use ITNs for fishing.

Methods

This study used qualitative and observational methods. Five waterside communities were identified, two each in the North, Central and Southern regions, representing a mix of lakeside and riverside settings. Fifteen focus group discussions were conducted with a total of 146 participants, including men, women, and community leaders.

Results

Respondents stated that they knew that ITNs should be slept under to protect from malaria. Respondents discussed financial hardships their communities were facing due to droughts, poverty, food scarcity, unemployment, and devaluation of the Malawian currency, the kwacha. Many described selling household goods, including clothes and cooking pots, to generate short-term income for their family. Though no respondents admitted to selling an ITN themselves, the practice was commonly known. Participants said that food shortages were forcing them to make difficult choices. Fishing with ITNs was reported to be common in the study sites, as a response to food insecurity, and was widely understood to be harmful over the longer term. Respondents felt that it was everyone’s responsibility to cut down on this practice, but that efforts to confiscate or burn nets and boats of those caught fishing with ITNs were counter-productive since boats, especially, were a required resource for a productive livelihood. Respondents feared that if the health workers, government officials and donors continued to see ITNs being misused for fishing, the distribution of free ITNs would end, which would worsen malaria in their communities.

Conclusions

Faced with economic hardships and food security crises, participants reported being forced to look for alternative incomes to feed their families. This sometimes included selling or repurposing their belongings, including ITNs, for income. This issue is complex and will require a community-led multisectoral response to preserve health, fisheries, and livelihoods.

PARENTS 2 study: consensus report for parental engagement in the perinatal mortality review process

OBJECTIVE

The PARENTS 1 study (Parents' Active Role and ENgagement in The review of their Stillbirth/perinatal death) found that parents would endorse the opportunity to give feedback into the perinatal mortality review (PNMR) process. In subsequent focus groups, healthcare professionals were positive about parental engagement, although they considered that there may be significant challenges. The objective of this study was to develop core principles and recommendations for parental engagement in PNMR in the UK.

METHODS

A two-round Delphi technique was followed to reach consensus on core principles for parental engagement in the PNMR process; Round 1 included a national consensus workshop and Round 2 an online questionnaire. The consensus meeting was attended by a national panel of stakeholders (clinical and academic experts, parent advocates, managers and commissioners) in stillbirth and neonatal and bereavement care. To develop recommendations for parental engagement, participants discussed four key areas comprising: communication with parents, including receiving feedback; the format of the PNMR meeting; the parental engagement pathway; and challenging aspects of engaging with parents in reviews. Content analysis was conducted to generate recommendations from the meeting for a subsequent anonymous web-based survey. Attendees of the consensus workshop and members of the PARENTS 2 Project Advisory Board were asked to rank recommendations using a 9-point Likert scale from 1 (not important) to 9 (critically important). It had been agreed a priori, in compliance with established Grading of Recommendations, Assessment, Development and Evaluation (GRADE) criteria, that 'consensus' would be achieved if over 70% of participants scored the principle as 'critical' (score of 7-9) and fewer than 15% scored the principle as 'not important' (score of 1-3). Principles for which consensus was achieved were included in the core recommendations.

RESULTS

Of the 29 invited stakeholders, 22 participated in the consensus meeting and 25 (86% response rate) in the subsequent online questionnaire in June 2017. Consensus was agreed on 12 core principles. Of the 25 participants, 96% agreed that a face-to-face explanation of the PNMR process was of critical importance, 72% considered that parents should be offered the opportunity to nominate a suitable advocate, 92% believed that responses to parents' comments should be formally documented, 96% indicated that it was vital for action plans to be translated into lessons learnt and that this process should be monitored, and 100% of stakeholders voted that a plain-English summary should be produced for the parents following the meeting. There was good agreement on a further seven principles.

CONCLUSIONS

Key national stakeholders were unanimously supportive of parental engagement in the PNMR process and agreed on core principles to make this process feasible, meaningful and robust. A 6-month pilot of parental engagement in the PNMR process (PARENTS 2 study) in two UK units took place after the consensus on core principles. In collaboration with the National Perinatal Epidemiology Unit, the findings will inform the national standardized PNMR tool. © 2018 The Authors.

Balancing Assessment with "In-Service Practical Training": A Case Report on Collaborative Curriculum Design for Delivery in the Practice Setting

Three Higher Education Institutions (HEIs) in Ireland are accredited to provide education and training, successful completion of which, entitles one to register as a pharmacist with the Pharmaceutical Society of Ireland (PSI). Legislation (2014) mandated that these HEIs replace their existing structure (four-year degree followed by a one-year internship), with a five-year ‘integrated Master’s programme’. Integration includes ‘in-service practical training’ (placement) at the beginning of Year 4 (four months), and the end of Year 5 (eight months). Year 4 placements do not have to be ‘patient-facing’. Students receive a Bachelor’s degree at the end of Year 4. The Affiliation for Pharmacy Practice Experiential Learning (APPEL), established by the HEIs, manages student placements, training establishments, preceptor training, the preceptors’ competency assessment process, and the virtual learning environment (VLE) that enables delivery of co-developed online modules aligned with placements in Years 4 and 5. This case report aims to describe the process by which this integration has taken place across and within these HEIs and the challenges faced by educators, students, preceptors, and other stakeholders along the way.

Human behaviour and residual malaria transmission in Zanzibar: findings from in-depth interviews and direct observation of community events

Background

Zanzibar has maintained malaria prevalence below 1% for the past decade, yet elimination remains elusive despite high coverage of core vector control interventions. As part of a study investigating the magnitude and drivers of residual transmission in Zanzibar, qualitative methods were utilized to better understand night time activities and sleeping patterns, individual and community-level risk perceptions, and malaria prevention practices.

Methods

A total of 62 in-depth interviews were conducted with community members and local leaders across six sites on Unguja Island, Zanzibar. Twenty semi-structured community observations of night-time activities and special events were conducted to complement interview findings. Data were transcribed verbatim, coded, and analysed using a thematic approach.

Results

Participants reported high levels of ITN use, but noted gaps in protection, particularly when outdoors or away from home. Routine household and community activities were common in evenings before bed and early mornings, while livelihood activities and special events lasted all or most of the night. Gender variation was reported, with men routinely spending more time away from home than women and children. Outdoor sleeping was reported during special events, such as weddings, funerals, and religious ceremonies. Participants described having difficulty preventing mosquito bites while outdoors, travelling, or away from home, and perceived higher risk of malaria infection during these times. Travel and migration emerged as a crucial issue and participants viewed seasonal workers coming from mainland Tanzania as more likely to have a malaria infection and less likely to be connected to prevention and treatment services in Zanzibar. Some community leaders reported taking the initiative to register seasonal workers coming into their community and linking them to testing and treatment services.

Conclusions

Targeting malaria interventions effectively is critical and should be informed by a clear understanding of relevant human behaviour. These findings highlight malaria prevention gaps in Zanzibar, and the importance of identifying new approaches to complement current interventions and accelerate the final phases of malaria elimination. Development and deployment of complementary interventions should consider human behaviour, including gender norms, that can influence exposure to malaria vectors and prevention practices. Expansion of community-level programmes targeting travellers and seasonal workers should also be explored.

Using a Human-Centered Design Approach to Determine Consumer Preferences for Long-Lasting Insecticidal Nets in Ghana

BACKGROUND

A human-centered design approach, paired with traditional research methods, was used to explore consumer preferences of middle-class Ghanaians for a long-lasting insecticidal net (LLIN) to be designed for the private-sector retail market.

METHODS

In March 2017, we conducted 9 focus groups with urban and rural middle-class Ghanaians across Ashanti, Greater Accra, and Western regions. A total of 78 participants (51 adults and 27 boarding school students) were involved in the focus groups. Participants were asked for their input on topics related to malaria prevention, LLIN perceptions and use behavior, as well as general consumer preferences related to the home and bedroom. They participated in a variety of exercises, such as rank ordering their preferences of various accessories that might be bundled with an LLIN and interacting with actual LLINs of different sizes and designs. The data were gathered and analyzed, using micro-interlocutor analysis framework to capture emergent themes.

RESULTS

LLINs are currently available through free distribution channels, but in most accounts, participants reported that the nets were inconvenient, uncomfortable, and not aesthetically pleasing, thus they were undesirable to use. For example, several participants described the process of hanging as well as entering and exiting the LLIN as challenging, stressful, and/or tedious. In addition, use of LLINs was considered to make people feel even hotter in an already warm climate as well as to leave users feeling confined within a small space. Finally, many participants discussed how to improve the look of LLINs including suggestions for additional colors, shapes, and hanging mechanisms to make the LLINs more compatible with their desired bedroom and home décor. Based on the participants' responses, we concluded that they would prefer LLINs that better reflect contemporary sensibilities. We devised and tested different LLIN attributes to address these points, focusing on a more convenient way to hang the net, a more attractive silhouette, and a zipper that allows the user to enter and exit with ease while still maintaining a sealed, mosquito-free space. A separate discrete choice experiment confirmed the attractiveness of these attributes by capturing the target population's willingness to pay for LLINs with said preference-congruent attributes.

CONCLUSION

Our human-centered design approach yielded consumer insights and preferences for novel LLIN designs for the private-sector retail market in Ghana. If this net design is successful, it could increase LLIN use among the middle class and catalyze the purchase of LLINs to support ongoing malaria control efforts.

Professional practice following regulatory change: An evaluation using principles of "Better Regulation"

BACKGROUND

The provisions in place internationally to regulate the practice of healthcare professionals have undergone significant change. However, this changing regulatory environment as experienced by healthcare professionals in the practice setting has not to date been widely researched.

OBJECTIVE

To describe the "lived experience" of pharmacists in community practice in Ireland of the model of regulation introduced by the Pharmacy Act 2007 and their perception of it as fulfilling the seven principles of "better regulation": Necessity; Effectiveness/Targeted; Proportionality; Transparency; Accountability; Consistency and Agility.

METHOD

20 community pharmacists purposively selected, shared their lived experiences of the Act, as implemented in a semi-structured interview. A qualitative content analysis incorporating a framework analysis based on the seven principles of better regulation was used to analyze the data.

RESULTS

The Act and its implementation by the Pharmaceutical Society of Ireland (PSI) was not perceived by community pharmacists overall as fulfilling the principles of better regulation. While there was agreement that the Act was necessary, its implementation by the PSI was not viewed as being effective, targeted, proportional and consistent. The PSI was considered to act as a deterrence regulator that is not adequately transparent or accountable. The Act is not sufficiently agile to respond to changes in pharmacy practice.

CONCLUSION

Community pharmacists acknowledge the need for the Pharmacy Act but perceive that the PSI needs to adopt a more responsive approach to implementation if the Act is to be considered a model of better regulation. The study findings are of interest as there is little published research on how regulation is experienced by healthcare professionals who are subject to its provisions. The principles of better regulation provide an effective qualitative methodology to examine models of professional regulation based on the "lived experience" of regulatees.

Explant of aortic stent grafts following endovascular aneurysm repair

Background

Failure of endovascular aneurysm repair may require explant of the stent graft in a subset of patients. We sought to assess outcomes in a cohort of patients undergoing explant of endovascular aneurysm repair in both emergency and elective settings.

Methods

Patients undergoing explant of endovascular aneurysm repair were identified from a prospectively maintained database, with additional information obtained through retrospective analysis of medical records.

Results

Over a 21-year period, 1997–2018 (May), there were 597 endovascular aneurysm repair procedures performed in our institution for abdominal aortic aneurysm. There were 19 endovascular aneurysm repair explants; five of these were referrals from other vascular centres. The median age was 73 years (range 46–81). The median length of time from insertion to explant was 39.2 months (range 0–153). Indications for elective explant were type Ia endoleak (n = 4), type 1b endoleak (n = 1), type II endoleak with increasing sac size (n = 1), type I/III endoleak (n = 1), type IV endoleak (n = 1), and increasing sac size without evident endoleak (type V, n = 2). The remaining nine cases were emergency procedures, with four patients presenting with rupture post endovascular aneurysm repair, four patients presenting with acute stent thrombosis, of which one also had a type 1a endoleak and one aorto-enteric fistula. There were no mortalities in the elective group and three mortalities in the emergency group (0 vs 33.3%, p = 0.087). Overall 30-day mortality was 15.8%

Conclusion

Explant of aortic stent grafts can be associated with high mortality and morbidity rates, especially in the emergent setting. Patient and device selection and post-operative surveillance remain vitally important to optimise outcomes post endovascular aneurysm repair.

Zika and travel in the news: a content analysis of US news stories during the outbreak in 2016-2017

OBJECTIVES

This study aimed to understand what information the US media communicated about Zika virus (ZIKV) and travel in 2016 and 2017.

STUDY DESIGN

We conducted a content analysis of news coverage about ZIKV and travel from April 5, 2016 to March 31, 2017.

METHODS

We obtained a stratified, random sample of English language, US print newspaper and television news coverage about ZIKV and travel. We developed a coding scheme to assess key messages in the news, including how ZIKV is transmitted, the symptoms and outcomes of ZIKV infection, and recommended prevention behaviors.

RESULTS

Almost all news stories mentioned mosquito-borne transmission (96.8%) and just over half mentioned sexual transmission (55.3%). News stories were more likely to talk about ZIKV outcomes (78.8%) than ZIKV symptoms (40.6%). However, outcomes affecting babies were mentioned more frequently than outcomes affecting adults. Recommendations included a wide array of protective behaviors, such as delaying or avoiding travel (77.6%) and using mosquito repellent (41.0%). However, few studies (10.9%) mentioned barriers to practicing ZIKV prevention behaviors.

CONCLUSIONS

Public health organizations and professionals can use these findings to help improve communication about future outbreaks of mosquito-borne illnesses. We also recommend conducting real-time monitoring of news media and frequent content analysis of news stories to ensure coverage provides the information the public needs.
