Human papillomavirus negative high grade cervical lesions and cancers: Suggested guidance for HPV testing quality assurance.

BACKGROUND: Some high-grade cervical lesions and cervical cancers (HSIL+) test negative for human papillomavirus (HPV). The HPV-negative fraction varies between 0.03 % and 15 % between different laboratories. Monitoring and extended re-analysis of HPV-negative HSIL+ could thus be helpful to monitor performance of HPV testing services. We aimed to a) provide a real-life example of a quality assurance (QA) program based on re-analysis of HPV-negative HSIL+ and b) develop international guidance for QA of HPV testing services based on standardized identification of apparently HPV-negative HSIL+ and extended re-analysis, either by the primary laboratory or by a national HPV reference laboratory (NRL). METHODS: There were 116 initially HPV-negative cervical specimens (31 histopathology specimens and 85 liquid-based cytology samples) sent to the Swedish HPV Reference Laboratory for re-testing. Based on the results, an international QA guidance was developed through an iterative consensus process. RESULT: Standard PCR testing detected HPV in 55.2 % (64/116) of initially "HPV-negative" samples. Whole genome sequencing of PCR-negative samples identified HPV in an additional 7 samples (overall 61.2 % HPV positivity). Reasons for failure to detect HPV in an HSIL+ lesion are listed and guidance to identify cases for extended re-testing, including which information should be included when referring samples to an NRL are presented. CONCLUSION: Monitoring the proportion of and reasons for failure to detect HPV in HSIL+ will help support high performance and quality improvement of HPV testing services. We encourage implementation of QA strategies based on re-analysis of "HPV negative" HSIL+ samples.

Academic conference posters: Describing visual impression in pharmacy education.

Background: Academic conference posters are a key communication before journal articles. Attention to visual attributes can enhance academic poster communication. Objective: This investigation's purpose was to create a visual impression measurement instrument, and then to describe and compare visual impression among scientific posters from an academic conference. Methods: A mixed-approach rubric was created to quickly measure visual impression of academic posters. Then, posters from a pharmacy education conference were retrospectively reviewed and scored. Visual impression was compared for traditional versus contemporary poster-formats. Various poster characteristics (poster-format, summary statement presence, abstract presence, wordiness, QR-code presence, logical sequencing, visuals) that might have impacted visual communication were coded. These characteristics were regressed onto visual impression scores. Results: Three-hundred seventy-eight posters were scored with sound inter-rater reliability. Contemporary poster-format scored significantly higher than traditional. Poster-format, abstract absence, lack of wordiness, QR-code presence, logical sequencing, and number of visuals were significant when regressed. Conclusion: Posters at one academic conference had varied visual impression. While a contemporary poster-format appeared more helpful, it was not a panacea; variation from poor through exemplary was seen with both poster-formats. Posters are not text-filled articles; displaying a combination of visuals/text clearly and concisely can help effective communication with academic posters.

Interacting within an asynchronous online interprofessional education workshop focused on social determinants of health.

BACKGROUND: Meaningful interprofessional education (IPE) involves students from at least two professions interacting to learn with, about, and from one another. Our objective was to describe a novel online approach used to create meaningful IPE within a social determinants of health (SDoH) workshop. INTERPROFESSIONAL EDUCATION ACTIVITY: This online workshop integrated four different professions' perspectives on SDoH (social-work, public-health, nursing, and pharmacy). Each six-student interprofessional team was assigned a local neighborhood. This week-long workshop had numerous activities (pre- and post-workshop quizzes, a SDoH-primer video, video self-introduction to teammates, a windshield questionnaire with two subsequent clinical cases, a post-workshop reflection, and post-workshop evaluation). For discussion, asynchronous video-based responses were used instead of traditional text-based discussion-boards. DISCUSSION: Quantitatively comparing quiz scores, students' SDoH knowledge increased with this workshop. Qualitatively from evaluations, most students found this workshop helpful and meaningful. Supporting use of video-based responses, many students' favorite aspect was interacting and collaborating within their interprofessional teams, although some students desired synchronous activities instead. Faculty facilitators confirmed that meaningful IPE interactions occurred. IMPLICATIONS: In short, students from multiple health-professions learned SDoH-content and, using video-based responses, interacted asynchronously during this online workshop. This report demonstrated one tool available to help facilitate meaningful IPE asynchronously. This asynchronous, online IPE workshop appears to be a promising format to be integrated with other in-person IPE sessions.

A Multifaceted Approach for Evaluating Hepatitis E Virus Infectivity In Vitro: Cell Culture and Innovative Molecular Methods for Integrity Assessment.

Hepatitis E virus is a prominent cause of viral hepatitis worldwide. In Western countries, most infections are asymptomatic. However, acute self-limiting hepatitis and chronic cases in immunocompromised individuals can occur. Studying HEV is challenging due to its difficulty to grow in cell culture. Consequently, the detection of the virus mainly relies on RT-qPCR, which cannot differentiate between infectious and non-infectious particles. To overcome this problem, methods assessing viral integrity offer a possible solution to differentiate between intact and damaged viruses. This study aims at optimizing existing HEV cell culture models and RT-qPCR-based assays for selectively detecting intact virions to establish a reliable model for assessing HEV infectivity. In conclusion, these newly developed methods hold promise for enhancing food safety by identifying approaches for inactivating HEV in food processing, thereby increasing food safety measures.

Hepatitis E virus in pork meat products and exposure assessment in Belgium.

Zoonotic hepatitis E virus (HEV) genotype 3 infections are the predominant cause of acute viral hepatitis in Europe, mostly associated with the consumption of HEV contaminated pork meat. In this study we looked at the HEV RNA positivity rate of pork meat products readily available from Belgian supermarkets and evaluated the overall HEV consumer exposure in a Belgian context. Two basic assessments were performed in a 'worst-case' scenario setting: one solely focusing on the contamination level of the product itself (ingredients and processing parameters) and another estimating the overall consumer exposure, taking into account consumption habits in Belgium. Non-thermal-processed ready-to-eat (i.e. ready for consumption without additional cooking step by consumer) pork meat products (e.g. raw dried sausages), had a high estimated HEV contamination level, while thermal-processed ready-to-eat pork meat products (e.g. pork liver pâté) had the highest overall consumer exposure estimates. Following these assessments, pork liver pâtés, raw dried hams and raw dried sausages (n = 54) were purchased from Belgian supermarkets (n = 3) and analyzed for HEV RNA by RT-PCR. In total, 31 % (n = 17) products tested positive. HEV RNA was found in 65 % of the pork liver pâtés, 15 % of raw dried hams and 0 % of raw dried sausages. Phylogenetic analysis of four isolates (all gt3c) from pork liver pâté samples showed similarities with human clinical cases from Germany and Belgium.

Using Rasch measurement for instrument rating scale refinement.

OUR SITUATION: Rasch measurement is an analysis tool that can provide validity evidence for instruments that attempt to measure student learning or other psychosocial behaviors, regardless if tools are newly created, modified, or previously developed. Rating scales are exceedingly common among psychosocial instruments and properly functioning rating scales are critical to effective measurement. Rasch measurement can help investigate this. METHODOLOGICAL LITERATURE REVIEW: Aside from using Rasch measurement from the beginning to help create rigorous new measurement instruments, researchers can also benefit from employing Rasch measurement on previously developed instruments that had not included Rasch measurement during development. This article is focused on Rasch measurement's unique analysis of rating scales. That is, Rasch measurement can uniquely help examine if and how an instrument's rating scale is functioning among newly studied respondents (who will likely differ from the originally researched sample). OUR RECOMMENDATIONS AND THEIR APPLICATION: After reviewing this article, the reader should be able to describe Rasch measurement, including how it is focused on fundamental measurement and how it differs from classical test theory and item-response theory, and reflect on situations in their own research where a Rasch measurement analysis might be helpful for generating validation evidence with a previously developed instrument. POTENTIAL IMPACT: In the end, Rasch measurement can offer a helpful, unique, rigorous approach to further developing instruments that scientifically measure, accurately and precisely.

Viral clade is associated with severity of symptomatic genotype 3 hepatitis E virus infections in Belgium, 2010-2018.

BACKGROUND & AIMS: HEV genotype (gt) 3 infections are prevalent in high-income countries and display a wide spectrum of clinical presentations. Host - but not viral - factors are reported to be associated with worse clinical outcomes. METHODS: Demographic, clinical, and biochemical data laboratory-confirmed HEV infections (by PCR and/or a combination of IgM and IgG serology) at the Belgian National Reference Centre between January 2010 and June 2018 were collected using standardised case report forms. Genotyping was based on HEV open reading frame 2 sequences. Serum CXCL10 levels were measured by a magnetic bead-based assay. H&E staining was performed on liver biopsies. RESULTS: A total of 274 HEV-infected individuals were included. Subtype assignment was possible for 179/218 viraemic cases, confirming gt3 as dominant with an almost equal representation of clades abchijklm and efg. An increased hospitalisation rate and higher peak serum levels of alanine aminotransferase, bilirubin, and alkaline phosphatase were found in clade efg-infected individuals in univariate analyses. In multivariable analyses, clade efg infections remained more strongly associated with severe disease presentation than any of the previously identified host risk factors, being associated with a 2.1-fold higher risk of hospitalisation (95% CI 1.1-4.4, p = 0.034) and a 68.2% higher peak of bilirubin levels (95% CI 13.3-149.9, p = 0.010), independently of other factors included in the model. In addition, acute clade efg infections were characterised by higher serum CXCL10 levels (p = 0.0005) and a more pronounced liver necro-inflammatory activity (p = 0.022). CONCLUSIONS: In symptomatic HEV gt3 infections, clade efg is associated with a more severe disease presentation, higher serum CXCL10 levels, and liver necro-inflammatory activity, irrespective of known host risk factors. CLINICAL TRIAL REGISTRATION: The protocol was submitted to clinicaltrials.gov (NCT04670419). IMPACT AND IMPLICATIONS: HEV genotype (gt) 3 infections display a wide spectrum of clinical presentations currently ascribed to host factors. Here we examined the role of viral factors on liver disease outcomes by combining viral phylogeny with clinical, biochemical, cytokine, and histological data from 274 Belgian adults infected with HEV presenting between 2010 and 2018. HEV gt 3 clade efg infections were associated with a more severe disease presentation, higher serum CXCL10 levels and liver necro-inflammatory activity, irrespective of known host risk factors. HEV gt3 clade-dependent clinical outcomes call for broad HEV gt3 subtyping in clinical practice and research to help identify those at higher risk for worse outcomes and to further unravel underlying virus-host interactions.

Hepatitis of unknown aetiology in children - epidemiological overview of cases reported in Europe, 1 January to 16 June 2022.

Following the report of an excess in paediatric cases of severe acute hepatitis of unknown aetiology by the United Kingdom (UK) on 5 April 2022, 427 cases were reported from 20 countries in the World Health Organization European Region to the European Surveillance System TESSy from 1 January 2022 to 16 June 2022. Here, we analysed demographic, epidemiological, clinical and microbiological data available in TESSy. Of the reported cases, 77.3% were 5 years or younger and 53.5% had a positive test for adenovirus, 10.4% had a positive RT-PCR for SARS-CoV-2 and 10.3% were coinfected with both pathogens. Cases with adenovirus infections were significantly more likely to be admitted to intensive care or high-dependency units (OR = 2.11; 95% CI: 1.18-3.74) and transplanted (OR = 3.36; 95% CI: 1.19-9.55) than cases with a negative test result for adenovirus, but this was no longer observed when looking at this association separately between the UK and other countries. Aetiological studies are needed to ascertain if adenovirus plays a role in this possible emergence of hepatitis cases in children and, if confirmed, the mechanisms that could be involved.

Decrease in incidence of oral anticoagulant-related intracerebral hemorrhage over the past decade in the Netherlands.

Background: Data on oral anticoagulant-related (OAC) intracerebral hemorrhage (ICH) incidence are scarce. Most studies on incidence time trends were performed before the introduction of Direct Oral Anticoagulants (DOACs). Between 2008 and 2018, the number of OAC-users in the Netherlands increased by 63%, with the number of DOAC-users almost equaling that of Vitamin K Antagonists (VKA)-users. We aimed to determine the recent total and OAC-related ICH incidence and assess changes over the last decade, including the effect of DOAC introduction. Methods: All adult non-traumatic ICH patients presenting in any of three hospitals in the enclosed region of South-Limburg, the Netherlands, were retrospectively included, during two 3-year time periods: 2007-2009 and 2017-2019. OAC-related ICH was defined as ICH in patients using VKAs or DOACs. We calculated the incidence rate ratio (IRR) between the two study periods. Results: In the 2007-2009 period, we registered 652 ICHs of whom 168 (25.8%) were OAC-related (all VKA). In the 2017-2019 period, we registered 522 ICHs, 121 (23.2%) were OAC-related (70 VKA and 51 DOAC). In 2007-2009, the annual incidence of total ICH and OAC-related ICH was 40.9 and 10.5 per 100,000 person-years, respectively, which decreased to 32.4 and 7.5 per 100,000 person-years in 2017-2019. The IRR for total ICH and OAC-related ICH was 0.67 (95%-CI: 0.60-0.75) and 0.58 (0.46-0.73), respectively. Conclusion: Both total ICH and OAC-related ICH incidence decreased over the past decade in South-Limburg, the Netherlands, despite the aging population and increasing number of OAC-users. The introduction of DOACs, and possibly an improved cardiovascular risk management and change in OAC prescription pattern, could explain these findings.

A case of convergent evolution: Several viral and bacterial pathogens hijack RSK kinases through a common linear motif.

Microbes have been coevolving with their host for millions of years, exploiting host resources to their own benefit. We show that viral and bacterial pathogens convergently evolved to hijack cellular mitogen-activated protein kinase (MAPK) p90-ribosomal S6-kinases (RSKs). Theiler's virus leader (L) protein binds RSKs and prevents their dephosphorylation, thus maintaining the kinases active. Recruitment of RSKs enables L-protein-mediated inhibition of eukaryotic translation initiation factor 2 alpha kinase 2 (EIF2AK2 or PKR) and stress granule formation. Strikingly, ORF45 protein of Kaposi's sarcoma-associated herpesvirus (KSHV) and YopM protein of Yersinia use the same peptide motif as L to recruit and activate RSKs. All three proteins interact with a conserved surface-located loop of RSKs, likely acting as an allosteric regulation site. Some unrelated viruses and bacteria thus evolved to harness RSKs in a common fashion, yet to target distinct aspects of innate immunity. As documented for Varicella zoster virus ORF11, additional pathogens likely evolved to hijack RSKs, using a similar short linear motif.

Last Matter: Introducing infographics to Methodology Matters.

Visual summaries are gaining momentum in the health sciences literature. The Journal is introducing a new article type-Last Matter (LM). These will consist of infographics that quickly summarize and visually describe topics typically addressed in more detail within Methodology Matters reviews. The primary goal is to provide readers with clear guidance related to one or two common issues, pitfalls, or points of confusion when conducting pharmacy education scholarship. In addition to a graphical summary, a key element of each LM is a list of recommended resources for readers interested in more detailed information. The first Last Matter published in this issue summarizes key concepts related to quality in qualitative research. The Journal hopes these infographics may be helpful to for readers to comprehend and share, as well as to influence future contributions to the pharmacy education literature.

Comparing Data Submitted by Public and Private Pharmacy Schools to the Opioid-Related Activities Database.

Objective. This investigation compared similarities and differences in education on opioids and opioid abuse between public and private US schools and colleges of pharmacy.Methods. The American Association of Colleges of Pharmacy has created and maintains an Opioid-Related Activities database for schools and colleges of pharmacy in the United States. With data from 2019, a mixed-methods design was used to triangulate quantitative analysis with a concurrent qualitative analysis. After describing, the data were compared to national statistics of schools and colleges of pharmacy (ie, number, type of school, and program structure). Data from the database on opioid activity types (ie, education, service, practice, research, and advocacy) were compared between private and public institutions, both quantitatively and qualitatively. The quantitative analysis used odds-ratios (for effect-size) and chi-square (for statistical significance), while the qualitative analysis employed word clouds to explore opioid-related activities descriptors.Results. One-hundred-seven of 144 US schools and colleges of pharmacy (74% response rate) provided their opioid-related activities information to AACP. The institutions (55 private, 52 public) had entered 436 unique opioid-related activities in the AACP database. Results of the quantitative and qualitative analyses triangulated that private institutions focused more on education-opioid-related activities, while public institutions offered more activities that involving research. Magnified to education-type opioid-related activities, faculty from private institutions often focused narrowly on an education event alone, while faculty from institutions often focused more broadly on education and other aspects such as funding, research and published articles.Conclusion. Overall, private and public US schools and colleges of pharmacy widely engaged in combatting the US opioid epidemic by training student pharmacists in this important area.

Providing Validation Evidence for a Clinical-Science Module: Improving Testing Reliability with Quizzes.

DESCRIPTION OF THE PROBLEM: High-stakes decision-making should have sound validation evidence; reliability is vital towards this. A short exam may not be very reliable on its own within didactic courses, and so supplementing it with quizzes might help. But how much? This study's objective was to understand how much reliability (for the overall module-grades) could be gained by adding quiz data to traditional exam data in a clinical-science module. THE INNOVATION: In didactic coursework, quizzes are a common instructional strategy. However, individual contexts/instructors can vary quiz use formatively and/or summatively. Second-year PharmD students took a clinical-science course, wherein a 5-week module focused on cardiovascular therapeutics. Generalizability Theory (G-Theory) combined seven quizzes leading to an exam into one module-level reliability, based on a model where students were crossed with items nested in eight fixed testing occasions (mGENOVA used). Furthermore, G-Theory decision-studies were planned to illustrate changes in module-grade reliability, where the number of quiz-items and relative-weighting of quizzes were altered. CRITICAL ANALYSIS: One-hundred students took seven quizzes and one exam. Individually, the exam had 32 multiple-choice questions (MCQ) (KR-20 reliability=0.67), while quizzes had a total of 50MCQ (5-9MCQ each) with most individual quiz KR-20s less than or equal to 0.54. After combining the quizzes and exam using G-Theory, estimated reliability of module-grades was 0.73; improved from the exam alone. Doubling the quiz-weight, from the syllabus' 18% quizzes and 82% exam, increased the composite-reliability of module-grades to 0.77. Reliability of 0.80 was achieved with equal-weight for quizzes and exam. NEXT STEPS: Expectedly, more items lent to higher reliability. However, using quizzes predominantly formatively had little impact on reliability, while using quizzes more summatively (i.e., increasing their relative-weight in module-grade) improved reliability further. Thus, depending on use, quizzes can add to a course's rigor.
