Abstract
BACKGROUND Open educational resources (OER) are educational materials licensed openly by authors, permitting usage, redistribution, and in some instances, modification. OER platforms thereby serve as a medium for distributing and advancing teaching materials and innovative educational methodologies. OBJECTIVE This study aims to determine the present state of OER in otorhinolaryngology and to examine the prerequisites for seamlessly integrating OER into the curricular teaching of medical schools, specifically through the design of two OER blended learning modules. METHODS OER content in the field of otorhinolaryngology was analyzed on OER platforms, ensuring its relevance to the German medical curriculum. Data protection concerns were addressed with legal counsel. The blended learning modules were developed in collaboration with medical students and subsequently published as OER. RESULTS AND CONCLUSION This project yielded the first OER from a German ENT department, tailored to the German medical curriculum. One significant barrier to OER use in medicine, more than in other fields, is data protection. This challenge can be navigated by obtaining consent to publish patient data as OER. OER hold the promise to play a pivotal role in fostering cooperation and collaboration among educators, aiding educators in lesson preparation, and simultaneously enhancing didactic quality.

Abstract
BACKGROUND Many approaches to management of medial malleolar fractures are described in the literature however, their morphology is under investigated. The aim of this study was to analyse the morphology of medial malleolar fractures to identify any association with medial malleolar fracture non-union or malunion. METHODS Patients who had undergone surgical fixation of their MMF were identified from 2012 to 2022, using electronic patient records. Retrospective analysis of their preoperative, intraoperative, and postoperative radiographs was performed to determine their morphology and prevalence of non-union and malunion. Lauge-Hansen classification was used to characterise ankle fracture morphology and Herscovici classification to characterise MMF morphology. RESULTS A total of 650 patients were identified across a 10-year period which could be included in the study. The overall non-union rate for our cohort was 18.77% (122/650). The overall malunion rate was 6.92% (45/650). Herscovici type A fractures were significantly more frequently mal-reduced at time of surgery as compared to other fracture types (p = .003). Medial wall blowout combined with Hercovici type B fractures showed a significant increase in malunion rate. There is a higher rate of bone union in patients who had been anatomically reduced. CONCLUSION The morphology of medial malleolar fractures does have an impact of the radiological outcome following surgical management. Medial wall blowout fractures were most prevalent in adduction-type injuries; however, it should not be ruled out in rotational injuries with medial wall blowouts combined with and Herscovici type B fractures showing a significant increase in malunions. Herscovici type A fractures had significantly higher malreductions. LEVEL OF EVIDENCE Level 3 - Retrospective Cohort Study.

Abstract
With the deepening reform of ideological and political education, Medical Parasitology teaching needs to update the teaching concept, change the teaching ideas, as well as keep trying to combine ideological and political education with the curriculum content closely. In addition to teaching students' basic knowledge and practical skills, teachers are needed to cultivate their moral literacy and political awareness through course teaching, so as to provide the basis for students' subsequent adaptations to social environments and jobs. Currently, the study of ideological and political education in Medical Parasitology teaching is still in the exploratory stage. Therefore, colleges and universities need to carry out effective construction of ideological and political education in Medical Parasitology teaching, in order to achieve good teaching outcomes and provide insights into ideological and political education in teaching.

Abstract
Prenatal screening has evolved rapidly following the introduction of non-invasive prenatal testing (NIPT), with screening now available for an increasing number of conditions. We explored the attitudes and expectations of women within the context of using NIPT to detect multiple different single gene and chromosome conditions during pregnancy. An online survey was used to assess these issues with a sample of 219 women from Western Australia. In our study, the majority of women (96%) support of the concept of expanded NIPT for single gene and chromosome conditions provided the test involves no risk to the pregnancy and can provide the parents with relevant medical information about the fetus at any stage of pregnancy. 80% believed that expanded NIPT for single gene and chromosome conditions should be available at any stage during pregnancy and 68% of women indicated that test cost would be a factor in determining their participation in testing. Under half (43%) of the women favored an option to terminate a pregnancy at any stage if the fetus had a medical condition that would interfere with day to day functioning. The majority (78%) of women believed that testing for multiple genetic conditions would provide reassurance and lead to the delivery of a healthy child.

Abstract
PURPOSE The purpose of this study is to examine perceptions and experiences of women who donate human milk and highlight various aspects of the breast milk donation process. STUDY DESIGN A cross-sectional descriptive study. METHODS An online survey was conducted with a convenience sample of women who donated milk at several milk banks in the United States. A questionnaire of 36 closed and open-ended items were developed and validated by the research team. Descriptive statistics and content analysis were used. Semantic content analysis involved three procedures: coding, categorizing text units, and refining the identified themes. RESULTS A total of 236 women who donated breast milk completed the questionnaire. Mean age of participants was 32.7±4.27 and 89.40% were non-Hispanic White women with a bachelor's degree (32.20%) or graduate degree (54.70%). Most participants were women who actively donated breast milk, ranging from one to four times. Two themes, facilitators and barriers of milk donation, were identified. Facilitators to milk donation included attitudes toward milk donation, commitment for donating, motivation in donating, and support. Barriers included personal factors, environment, milk donor process, and psychosocial factors. CLINICAL IMPLICATIONS Nurses, health care providers, and lactation professionals should educate women about milk donation resources and opportunities. Strategies to increase awareness about milk donation among underrepresented groups such as women of color are highly recommended. Future research is needed to further explore specific factors that increase milk donation awareness and minimize barriers to potential donors.

Abstract
Increased mitotic activity is associated with the genesis and aggressiveness of many cancers. To assess the clinical value of mitotic activity as prognostic biomarker, we performed a pan-cancer study on the mitotic network activity index (MNAI) constructed based on 54-gene mitotic apparatus network. Our pan-cancer assessment on TCGA (33 tumor types, 10,061 patients) and validation on other publicly available cohorts (23 tumor types, 9,209 patients) confirmed the significant association of MNAI with overall survival, progression-free survival, and other prognostic endpoints in multiple cancer types, including lower-grade gliomas (LGG), breast invasive carcinoma (BRCA), as well as many others. We also showed significant association between MNAI and genetic instability, which provides a biological explanation of its prognostic impact at pan-cancer landscape. Our association analysis revealed that patients with high MNAI benefitted more from anti-PD-1 and Anti-CTLA-4 treatment. In addition, we demonstrated that multimodal integration of MNAI and the AI-empowered Cellular Morphometric Subtypes (CMS) significantly improved the predictive power of prognosis compared to using MNAI and CMS alone. Our results suggest that MNAI can be used as a potential prognostic biomarker for different tumor types toward different clinical endpoints, and multimodal integration of MNAI and CMS exceeds individual biomarker for precision prognosis.

Abstract
Intracranial electroencephalography (iEEG) presents a unique opportunity to extend human neuroscientific understanding. However, typically iEEG is collected from patients diagnosed with focal drug-resistant epilepsy (DRE) and contains transient bursts of pathological activity. This activity disrupts performances on cognitive tasks and can distort findings from human neurophysiology studies. In addition to manual marking by a trained expert, numerous IED detectors have been developed to identify these pathological events. Even so, the versatility and usefulness of these detectors is limited by training on small datasets, incomplete performance metrics, and lack of generalizability to iEEG. Here, we employed a large annotated public iEEG dataset from two institutions to train a random forest classifier (RFC) to distinguish data segments as either 'non-cerebral artifact' (n = 73,902), 'pathological activity' (n = 67,797), or 'physiological activity' (n = 151,290). We found our model performed with an accuracy of 0.941, specificity of 0.950, sensitivity of 0.908, precision of 0.911, and F1 score of 0.910, averaged across all three event types. We extended the generalizability of our model to continuous bipolar data collected in a task-state at a different institution with a lower sampling rate and found our model performed with an accuracy of 0.789, specificity of 0.806, and sensitivity of 0.742, averaged across all three event types. Additionally, we created a custom graphical user interface to implement our classifier and enhance usability.

Abstract
The access to molecular collections worldwide greatly improves the quality of scientific research by making a growing number of data available for investigation. The efforts on digitisation also aim at facilitating the exchange of material between institutions and researchers that must follow regulations in place and respect best practice. The handbook presented here proposes a workflow to follow to safely exchange materials, in accordance with international laws and legislation. We make numerous recommendations here to help the institutions and researchers to navigate the legal and administrative procedures, in order to manage molecular collections in the best way possible.

Abstract
A survey of 111 urban constructed stormwater wetlands (median watershed area = 86.8 ha) was conducted to identify the major pesticides present and to determine their major catchment sources (residential, industrial, commercial, sporting ovals) and associations with catchment imperviousness. Melbourne, Australia, has separate stormwater and sewerage systems and these wetlands are designed to treat urban stormwater. To maximise the pesticides that could be detected, three types of passive samplers (POCIS, Chemcatcher® SDB-XC and Chemcatcher® C18) were deployed, along with collection of fine sediments. A total of 231 pesticides were screened using these methods. Pesticides that were detected in >5 % of wetlands were checked to determine their registered use in urban areas using an Australian government database (PubCris). Twenty-five pesticides were detected in >5 % of wetlands: 4 pesticides were associated with non-urban land uses (agriculture and forests), another 4 pesticides had no known registered use in urban areas and 17 were associated with urban areas. The pesticides associated with urban areas were the herbicides simazine, diuron, metolachlor, bromacil, propyzamide and paclobutrazol, the fungicides tebuconazole, propiconazole, metalaxyl, trifloxystrobin, iprodione and carbendazim and the insecticides fipronil, bifenthrin, chlorantraniliprole, thiamethoxam and permethrin. Atrazine was also detected in 59 % of wetlands but has not been registered for urban uses in Australia since 2010. It's presence in Melbourne may be due to legacy issues or aerial transportation from rural areas where it's still widely used in crop cultivation. Generally, the major urban catchment source of pesticides is from residential areas (particularly fipronil and simazine), most likely in wood preservatives, paints and from weed or insect control. Many of these widely used pesticides were correlated with increased catchment imperviousness. Some pesticides (bromacil and imidacloprid) were correlated with commercial premises and chlorantraniliprole was correlated with the presence of sporting ovals in the catchment. No pesticides were specifically correlated with industrial areas. The use of passive samplers and fine sediments, in conjunction with detailed land use mapping of stormwater wetland catchments is very effective and efficient in monitoring and sourcing pesticide contamination in urban environments.

Abstract
Background: WT1 deletions are associated with nephroblastomas, WT mutations are associated with 46, XY sex reversal. It is unclear why only a few WT1 deletions are associated with sex reversal. Case report. This 46, XY female had a 15.2 MB interstitial deletion of 11p14.1p11.2, which included WT1 and FSHB. No pathogenic abnormalities were identified in 156 other genes associated with disorders of sexual development. Bilateral gonadoblastomas were incidentally diagnosed at 17 months of age at the time of prophylactic gonadectomies. She was treated without biopsy for bilateral nephroblastomas radiologically identified at 18 months of age. Bilateral partial nephrectomies contained treated intralobular nephrogenic rests. Conclusion: It is unclear why WT1 deletions are less associated with 46, XY sex reversal than WT1 mutations. Treating suspected nephroblastomas without biopsy, even in patients with syndromes associated with bilateral nephroblastomas, may still lead to diagnostic and therapeutic uncertainties.

Abstract
Abstract
Introduction
The National End of Life Care Strategy highlighted the need for individualised care plans accessible to the multi-disciplinary team. Care planning tools have been shown to improve documentation, with proformas providing a systematic approach to recording EOL discussions. Our initial staff survey highlighted a lack of familiarity with required EOLC documentation. We aimed to increase awareness of existing documentation proformas and to improve EOLC documentation on an elderly care ward.
Methods
A Driver Diagram increased understanding of the principles underlying excellent EOLC and aided development of change ideas. The Model for Improvement allowed identification of measurable aims. 20 patient notes were reviewed fortnightly, including patients who had died since the previous intervention.
Results
Three PDSA cycles were completed, changes were measured by evaluating patient documentation. The first PDSA cycle involved providing training to nursing colleagues. Step-by-step teaching on the use of Cerner EOL documentation demonstrated a 15% increase in completed care plans. The second cycle (placing posters around the ward) - detailing how to access and document care plans resulted in a 5% increase. The third cycle (25% improvement) involved education sessions for ward doctors.
Conclusions
Comprehensive documentation is key to ensuring good EOLC, as it enables continuity of care and improves MDT communication. Withdrawal of the Liverpool Care Pathway resulted in a need for individualised care plans. Active interventions including face-to-face teaching were more effective than passive (posters) in improving documentation. Limitations included small sample sizing, likely due to a lack of engagement with questionnaires and inclusion criteria. Only documentation of deceased patients was analysed, excluding patients discharged home or transferred to hospice. We aim to extend to other elderly care wards and to integrate documentation training into junior doctor induction. A review of existing EOL proformas and their ease of access may also be considered.

Abstract
Abstract
Background
In 2020, 28% of all hip fractures in Ireland were discharged to off-site rehabilitation. The annual Irish Hip Fracture Database (IHFD) report captures patient outcomes at the point of acute discharge however patient outcomes at discharge from offsite rehabilitation are unknown.
Methods
A multi-site retrospective audit was completed examining hip fracture outcomes for patients admitted to four post-acute rehabilitation hospitals during 2021, using IHFD HIPE portals as well as local databases. Descriptive statistics including demographics, pre-fracture mobility as well as outcomes measured including acute length of stay, rehabilitation length of stay, discharge destination and independence with mobility on discharge from rehabilitation. A comparison analysis between sites was completed.
Results
A total of 445 patients were admitted post hip fracture to the four rehabilitation hospitals in 2021. Most were female (69%, n=307), mean age 82.5, 49% lived alone and most (55%) had low pre-fracture mobility as measured by New Mobility Score of 0-6. The mean acute length of stay was 11.8 days and rehabilitation stay 37.6 days. Most (90.2% of complete data, n=333) discharged home, 4.5% (n=17) were transferred to hospital, 3.2% (n=12) were newly admitted to nursing home and 1% (n=4) died. Most (82.2% of complete data, n=256) were independently mobile (CAS 6) at discharge from rehabilitation. There was no significant difference in patient profile between sites however there were significant difference in both acute length of stay (median range 8-13days) as well as rehabilitation length of stay (median range 16-39days).
Conclusion
The findings of this audit provide a new perspective on recovery post hip fracture and insight into longer term hip fracture outcomes. It shows that data collection is feasible in off-site rehabilitation units and should be considered for inclusion in the IHFD. Further work could explore the establishment of standards of care in the post-acute phase of hip fracture rehabilitation.

Abstract
BACKGROUND Non-invasive prenatal testing (NIPT) using cell-free DNA (cfDNA) has expanded from detecting chromosome aneuploidy to testing for a variety of genetic conditions, including some select single gene disorders. As next generation sequencing/whole exome sequencing technology develops, it may be possible to expand NIPT of cfDNA to identify hundreds of single gene and chromosomal disorders in a fetus, thereby increasing the complexity of pretest counselling and parental decision-making. AIM The aim of this study was to assess the views of women on the phenotypes of genetic conditions potentially detectable with expanded NIPT that they would consider severe enough to warrant pregnancy termination. MATERIALS AND METHODS Using multiple clinical scenarios, we asked women via an online survey about the early detection of several well-described genetic phenotypes in pregnancy that in theory could be detected by expanded NIPT. RESULTS Two hundred and nineteen women participated in this study. There was high support for early diagnosis and the option for termination of pregnancy in conditions perceived as severe (52-71%). Women expressed a preference for testing to be provided by general practitioners and assigned a high value to genetic counselling support (75-90%). In the case of a continuing pregnancy, women recognised the essential role of ongoing psychosocial counselling for family members and childhood early intervention programs. CONCLUSION Women expressed clear preferences for termination of pregnancy for severe conditions and as early in gestation as feasible. Information and support from genetic counsellors are a highly valued resource in decision-making following a prenatal diagnosis of a fetal genetic abnormality.

Abstract
IMPORTANCE Logistical challenges such as travel time and distance to a clinical trial site can be a barrier to patient participation. The association of remote technology use and other decentralization tools that can reduce these barriers with likelihood to enroll in cancer trials is not well understood. OBJECTIVE To assess the association of remote technology and other decentralization tools used to reduce participation-related time and travel with the likelihood to enroll in cancer clinical trials. DESIGN, SETTING, AND PARTICIPANTS Between July 6 and September 8, 2021, a 41-question, cross-sectional, internet-based survey was administered to patients with cancer and survivors of cancer in the US who had been diagnosed with or treated for cancer in the past 7 years. MAIN OUTCOMES AND MEASURES Increase in self-reported likelihood to enroll in cancer clinical trials that use remote technology and other decentralization tools to decrease the need for travel to the trial site. RESULTS There were 1183 survey respondents, with a mean (SD) age of 58.2 (12.5) years. Respondents self-reported their gender, race and ethnicity, cancer type, and treatment status. Of the 1183 respondents, 848 (72%) were female, 296 (25%) were male, 8 (1%) were other/nonbinary, and 31 (3%) declined to answer. With regard to race, 28 respondents (3%) were American Indian or Alaska Native, 25 (2%) were Asian, 234 (20%) were Black or African American, 20 (2%) were Native Hawaiian or Other Pacific Islander, 825 (70%) were White, and 51 (4%) declined to answer. With regard to ethnicity, 115 respondents (10%) were Hispanic, Latino/Latina, or of Spanish origin, whereas 1017 (86%) were not and 51 (4%) declined to answer. Regarding cancer type and treatment status, 483 respondents (41%) either had or had survived breast cancer and 325 (28%) were being treated for cancer during the survey period. Individuals older than 55 years were more likely to say that they would only participate in trials no farther from their home than their regular care health care practitioner compared with younger respondents (26% vs 16%, respectively; P = .02). Higher-income earners (ie, those in households earning >$125 000/y) were significantly more likely than lower-income earners (ie, those in households earning <$70 000/y) to say they would participate in trials requiring additional effort (62% vs 41%, respectively; P = .03). If given the opportunity to enroll in a cancer clinical trial that required travel farther than their regular care, a majority of respondents (range, 60%-85%) indicated that they would be more likely to participate if the trial used remote technology and other tools to decrease the need for travel to a trial site. CONCLUSIONS AND RELEVANCE In this cross-sectional study, the survey findings suggest that cancer clinical trials leveraging remote technology and decentralization tools to reduce patient time and travel burden associated with participation may increase the patient consent rate.

Abstract
The most cost-effective way of protecting the population from radon is to ensure that new dwellings are built to prevent the entry of this gas from the ground below the building. One of the most common methods used to protect buildings from radon is the installation of a system to depressurize the subsoil below the building, reducing the ingress of the gas indoors. Laboratory based research has shown that the use of a wind-driven passive radon sump and static cowl has significant potential to protect new buildings in Ireland through depressurization. A field trial of this system was carried out in a sample of new Irish dwellings built to the requirements of Irish Building Regulations. The study focused on six unoccupied, adjacent, south-east facing dwellings of identical construction. The variables of occupancy, geology, building type, building material and weather were all controlled for, consequently, the study was carried out under highly controlled conditions. The radon levels in each of the dwellings were measured over a 6-week period under three test conditions: the passive sump closed, the passive sump open and the passive sump open with a static cowl installed. The results show an average reduction of 65% in radon levels due to the installation of a wind-driven passive sump. The cumulative effect of the installation of a passive sump plus a static cowl was an average reduction in radon levels of 75%. The number of observations that exceed the Government's Reference Level for dwellings of 200 Bq/m3 was reduced from 38% with the passive sump closed to 9% when the passive radon sump was in operation and 0% when both the passive radon sump and static cowl were installed. These results are statistically significant, and the cost is estimated at €100 per dwelling. The study concludes that the installation of a passive sump fitted with a static cowl in new dwellings is a low cost, effective method of reducing radon exposure in new Irish dwellings.

Abstract
BACKGROUND Systemic lupus erythematosus (SLE) risk has been associated with pesticide use, but evidence on specific pesticides or other agricultural exposures is lacking. We investigated history of pesticide use and risk of SLE and a related disease, Sjögren's syndrome (SS), in the Agricultural Health Study. METHODS The study sample (N = 54,419, 52% male, enrolled in 1993-1997) included licensed pesticide applicators from North Carolina and Iowa and spouses who completed any of the follow-up questionnaires (1999-2003, 2005-2010, 2013-2015). Self-reported cases were confirmed by medical records or medication use (total: 107 incident SLE or SS, 79% female). We examined ever use of 31 pesticides and farm tasks and exposures reported at enrollment in association with SLE/SS, using Cox regression to estimate hazard ratios (HR) and 95% confidence intervals (CI), with age as the timescale and adjusting for gender, state, and correlated pesticides. RESULTS In older participants (>62 years), SLE/SS was associated with ever use of the herbicide metribuzin (HR 5.33; 95%CI 2.19, 12.96) and applying pesticides 20+ days per year (2.97; 1.20, 7.33). Inverse associations were seen for petroleum oil/distillates (0.39; 0.18, 0.87) and the insecticide carbaryl (0.56; 0.36, 0.87). SLE/SS was inversely associated with having a childhood farm residence (0.59; 0.39, 0.91), but was not associated with other farm tasks/exposures (except welding, HR 2.65; 95%CI 0.96, 7.35). CONCLUSIONS These findings suggest that some agricultural pesticides may be associated with higher or lower risk of SLE/SS. However, the overall risk associated with farming appears complex, involving other factors and childhood exposures.

Abstract
Abstract
Background
Postural hypotension contributes significantly to falls in frail older people. The RCP recommend that all inpatients >65 years have a lying and standing blood pressure (L&SBP) performed early. We recognised that there was a need to improve the understanding, measurement and consistency of documentation for L&SBP on our ward, a 20-bedded acute MFE ward with many patients at risk of falls.
Methods
This project incorporates two PDSA cycles with three data collection points. We began with baseline measurements of the proportion of patients with: 1) L&SBP recorded within two working days of arrival 2) BP recorded at 1 and 3 minutes, and 3) documentation of associated symptoms. Patients were excluded where it was not possible or appropriate to perform L&SBP. We then carried out a qualitative questionnaire to understand the barriers for staff performing L&SBPs and potential solutions. Our first intervention was to design and deliver a teaching session to all nurses and health care assistants. After re-audit, we created a poster highlighting guidelines for measuring and documenting L&SBPs, and reinforced the learning at MDMs We reviewed the notes of all eligible patients on the ward before and after each intervention.
Results
Our questionnaire revealed useful insights including time constraints and uncertainty of where to document results—these findings allowed us to develop bespoke training for our team.
Discussion
This project demonstrates that junior doctor-led teaching and working with MDT colleagues improves the identification of postural hypotension on a ward. Reinforcement of learning is important.

Abstract
Abstract
Background
& Aims Visiting restrictions during the COVID-19 pandemic resulted in reduced and inconsistent communication with the next-of-kin of elderly inpatients. This project aimed to improve communication between doctors and patients’ relatives in accordance with the GMC Good Medical Practice guidelines which outline that doctors ‘must be considerate to those close to the patient and be sensitive and responsive in giving them information and support’.
Methods
We created a virtual whiteboard on an elderly care ward in an inner London hospital documenting patient demographics, details of named next-of-kin and when they had been contacted. We aimed to update next-of-kin within 48-hours of ward admission and subsequently twice weekly. The outcome was measured via identical ‘pre- and post-intervention’ questionnaires recording the next-of-kin’s satisfaction with communication from the doctors. Questionnaires included 11 questions utilising a 5-point Likert scale for satisfaction. Results were anonymised and analysed using Microsoft Excel.
Results
Satisfaction with communication improved in 10 of the 11 domains of the questionnaire following intervention. Cumulative satisfaction scores post-intervention (N = 13) in comparison to pre-intervention (N = 25) were closer to the total possible satisfaction score per question for these 10 domains. The mean cumulative satisfaction score across all domains was 60% post-intervention compared with 44% pre-intervention. Satisfaction following intervention was particularly improved in the domains of frequency of communication (60% post-intervention.
32.8% pre-intervention) and how adequately questions and concerns were addressed (69.2% post-intervention; 45.6% pre-intervention).
Conclusion
During the COVID-19 pandemic healthcare professionals have had to adapt in communicating with patients’ next-of-kin. Our Introduction of robust standards and a virtual whiteboard to track communication resulted in improved satisfaction and proved useful in adapting to remote communication. We propose that similar practice and standards are extended across additional wards to encourage widespread optimal and consistent communication between doctors and patients’ relatives, an integral part of patient care.

Abstract
Round cells in seminal fluid are defined as either leucocytes or immature germ cells. Laboratories undertaking semen analysis often report these combined as a concentration, with no further review, comment or direction for clinician action or review. Although numerous publications discuss the possible clinical relevance of these cells (particularly leucocytes) in infertility, the methods employed to differentiate them are often beyond the scope of most diagnostic laboratories. This paper aims to support healthcare scientists in understanding the clinical significance of round cells and aid their identification, differentiation and interpretation. This will support the quality of care the patient receives and direct clinicians to further considerations that may be appropriate for their patient and should consequently reduce indiscriminate and unnecessary use of antibiotics.

Abstract
A 2018 estimate indicates that there were 226,057 radon-attributable lung cancer deaths in 66 countries that had representative radon surveys. This is a shocking figure, and as it comes from only 66 countries it underestimates the worldwide death toll. Any research that enables countries to conduct representative radon surveys and to understand better the risk to citizens from radon is surely welcome. We hope this paper provides a useful methodology for estimating population risk. The estimation of population weighted average indoor radon levels requires statistically valid sampling methodologies that use a representative sample of occupied homes throughout the country. A literature review indicates that in many population weighted surveys, the sampling methodology may not have been designed to do this. This paper describes a simple, resource efficient methodology which produces statistically valid and reliable estimates based on a small scale sample that is representative of the population distribution. The resource efficient design of this study enables it to be repeated at frequent intervals providing for a longitudinal analysis of the population risk from indoor radon. This survey was conducted in Ireland using 653 measurements and a representative sampling strategy to provide a baseline population weighted radon exposure for future comparisons. This study estimates the average population weighted indoor radon concentration in Ireland to be 97.83 Bq m-3 (95% Confidence Interval 90.69 Bq m-3 to 105.53 Bq m-3), and that there are an estimated 350 lung cancer cases and 255 deaths per year due to radon exposure. The mortality rate of 5.3 per 100,000 due to indoor radon, demonstrates that radon remains one of the highest preventable causes of death in Ireland.

Abstract
OBJECTIVE We recently proposed a spectrum-based model of the awake intracranial electroencephalogram (iEEG) (Kalamangalam et al., 2020), based on a publicly-available normative database (Frauscher et al., 2018). The latter has been expanded to include data from non-rapid eye movement (NREM) and rapid eye movement (REM) sleep (von Ellenrieder et al., 2020), and the present work extends our methods to those data. METHODS Normalized amplitude spectra on semi-logarithmic axes from all four arousal states (wake, N2, N3 and REM) were averaged region-wise and fitted to a multi-component Gaussian distribution. A reduced model comprising five key parameters per brain region was color-coded on to cortical surface models. RESULTS The lognormal Gaussian mixture model described the iEEG accurately from all brain regions, in all sleep-wake states. There was smooth variation in model parameters as sleep and wake states yielded to each other. Specific observations unrelated to the model were that the primary cortical areas of vision, motor function and audition, in addition to the hippocampus, did not participate in the 'awakening' of the cortex during REM sleep. CONCLUSIONS Despite the significant differences in the appearance of the time-domain EEG in wakefulness and sleep, the iEEG in all arousal states was successfully described by a parametric spectral model of low dimension. SIGNIFICANCE Spectral variation in the iEEG is continuous in space (across different cortical regions) and time (stage of circadian cycle), arguing for a 'continuum' hypothesis in the generative processes of sleep and wakefulness in human brain.

Abstract
DNA double-strand breaks arise in vivo when a dicentric chromosome (two centromeres on one chromosome) goes through mitosis with the two centromeres attached to opposite spindle pole bodies. Repair of the DSBs generates phenotypic diversity due to the range of monocentric derivative chromosomes that arise. To explore whether DSBs may be differentially repaired as a function of their spatial position in the chromosome, we have examined the structure of monocentric derivative chromosomes from cells containing a suite of dicentric chromosomes in which the distance between the two centromeres ranges from 6.5 kb to 57.7 kb. Two major classes of repair products, homology-based (homologous recombination (HR) and single-strand annealing (SSA)) and end-joining (non-homologous (NHEJ) and micro-homology mediated (MMEJ)) were identified. The distribution of repair products varies as a function of distance between the two centromeres. Genetic dependencies on double strand break repair (Rad52), DNA ligase (Lif1), and S phase checkpoint (Mrc1) are indicative of distinct repair pathway choices for DNA breaks in the pericentromeric chromatin versus the arms. A challenge in chromosome biology is to integrate the linear code with spatial organization and chromosome dynamics within the nucleus. The major sub-division of function in the nucleus is the nucleolus, the site of ribosomal RNA synthesis. We report that the pericentromere DNA surrounding the centromere is another region of confined biochemistry. We have found that chromosome breaks between two centromeres that both lie within the pericentromeric region of the chromosomes are repaired via pathways that do not rely on sequence homology (MMEJ or NHEJ). Chromosome breaks in dicentric chromosomes whose centromeres are separated by > 20 kb are repaired via pathways that rely mainly on sequence homology (HR, SSA). The repair of breaks in the pericentromere versus breaks in the arms are differentially dependent on Rad52, Lif1, and Mrc1, further indicative of spatial control over DNA repair pathways.

Abstract
Abstract
Introduction
Delirium is still perceived as a “geriatric medicine competency”, despite its high prevalence across most specialties. Collective multi-disciplinary team performance in implementation of multi-component interventions is key. Simulation training incorporates the complex interplay of non-technical factors, specifically, role recognition and empowerment, inter-personal skills and teamwork that are pivotal in delivering effective delirium care.
Methods
Funding was approved by Health Education England. 2 pilot teaching sessions were arranged in the simulation ward. 3 scenarios were developed, each requiring a facilitator, an actor and three participants- a foundation-year doctor, a nurse/healthcare assistant and a therapist. Scenario 1 dealt with a patient with hypoactive delirium with focus on identification and multidisciplinary optimisation. Scenario 2 challenged participants with management of an agitated patient. Scenario 3 involved discharging a patient with resolving delirium and a reluctant relative, with emphasis on mental capacity assessment. Communication, patient risk assessment and challenging perceived role barriers were global themes. Participant feedback was captured using unstructured interviews and pre- and post-session 5-point Likert confidence scale in various learning outcomes.
Results
16 participants were included- 4 foundation year doctors, 3 therapists, 2 healthcare assistants and 7 nurses. There was an average improvement in Likert confidence scales in all measured learning outcomes. All participants would recommend the course to their colleagues (average Likert scale 4.9). Qualitative feedback appraised the course for demonstration of de-escalation communication strategies, the application of mental capacity and recognition of early discharge planning.
Conclusion
Simulation training targeted at multi-disciplinary groups is an effective way to deliver teaching on delirium. It contextualises synergistic operation of different skills and personal accountability in influencing patient management. The challenge to its potential remains its adoption as mandatory training for various disciplines involved in care of older adults and its implementation at a wider-scale, to assure cost effectiveness.

Abstract
The now 5-year collaboration between the Indiana Blood Center, now Versiti Blood Center of Indiana, and The Milk Bank has increased the number of human milk donors, improved the collection and processing of donor milk, and improved awareness of this lifesaving resource. The Indiana Blood Center provides greater visibility for The Milk Bank, creating more opportunities to reach potential donors, and can provide the screening blood test for potential donors to become approved human milk donors. The resources of the multiple locations of the Indiana Blood Center permitted the formation of new milk depots in five different cities and quicker transportation of donated milk through their active courier system. This partnership most importantly has improved awareness for both lifesaving missions to the communities they serve.

Abstract
There is little evidence in the veterinary literature to determine if antihistamines are as effective as glucocorticoids in the management of atopic dermatitis in dogs. Two randomised control trials directly compared an antihistamine, fexofenadine, to methylprednisolone although one was a small pilot study and only used four dogs in each treatment group. The third study was a cross-over placebo-controlled trial testing a variety of antihistamines and prednisone with limited reporting of statistical analysis of the data. None provide sufficient quality of evidence to recommend the use of antihistamines over glucocorticoids and further comparative study is needed.

Abstract
OBJECTIVES Adverse childhood experiences (ACEs) have a negative impact on childhood health, but their impact on education outcomes is less well known. We investigated whether or not ACEs were associated with reduced educational attainment at age 7 and 11 years. STUDY DESIGN The study design used in the study is a population-based electronic cohort study. METHODS We analysed data from a total population electronic child cohort in Wales, UK. ACEs (exposures) were living with an adult household member with any of (i) serious mental illness, (ii) common mental disorder (CMD), (iii) an alcohol problem; (iv) child victimisation, (v) death of a household member and (vi) low family income. We used multilevel logistic regression to model exposure to these ACEs and not attaining the expected level at statutory education assessments, Key Stage (KS) 1 and KS2 separately, adjusted for known confounders including perinatal, socio-economic and school factors. RESULTS There were 107,479 and 43,648 children included in the analysis, with follow-up to 6-7 years (KS1) and 10-11 years (KS2), respectively. An increased risk of not attaining the expected level at KS1 was associated with living with adult household members with CMD (adjusted odds ratio [aOR]: 1.13 [95% confidence interval [CI]: 1.09-1.17]) or an alcohol problem (adjusted odds ratio [aOR]: 1.16 [95% confidence interval [CI]: 1.10-1.22]), childhood victimisation (adjusted odds ratio [aOR]: 1.58 [95% confidence interval [CI]: 1.37-1.82]), death of a household member (adjusted odds ratio [aOR]: 1.14 [95% confidence interval [CI]: 1.04-1.25]) and low family income (adjusted odds ratio [aOR]: 1.92 [95% confidence interval [CI]: 1.84-2.01]). Similar results were observed for KS2. Children with multiple adversities had substantially increased odds of not attaining the expected level at each educational assessment. CONCLUSION The educational potential of many children may not be achieved due to exposure to adversity in childhood. Affected children who come in to contact with services should have relevant information shared between health and care services, and schools to initiate and facilitate a coordinated approach towards providing additional support and help for them to fulfil their educational potential, and subsequent economic and social participation.

Abstract
BACKGROUND Since the epidemiology of canine and feline dermatophytosis might evolve in response to chronological, sociological and ecological factors, the authors studied the occurrence of dermatophyte pathogens over 27 years subsequent to the last major UK survey. METHODS Dermatophyte culture submission records from dogs and cats to the Royal Veterinary College Diagnostic Laboratory in England between 1991 and 2017 were reviewed. Samples were routinely cultured aerobically at 26°C for up to four weeks on Sabouraud's dextrose agar containing cycloheximide and chloramphenicol; dermatophytes were identified using conventional phenotypic methods. RESULTS Proportional isolation from cats (15.9 per cent of 1389) exceeded that of dogs (8.1 per cent of 2193) (P<0.001). Together, Microsporum canis and Trichophyton mentagrophytes accounted for 91.9 per cent (n=203) and 80.2 per cent (n=142) of isolations from cats and dogs, respectively. M canis was more frequently (P<0.001) isolated from cats and dogs under two years of age. Dermatophytes were more frequent (P≤0.001) in samples from first-opinion rather than referral practice, and from Jack Russell and Yorkshire terriers and from Persian and chinchilla cats (P≤0.002). CONCLUSIONS M canis and T mentagrophytes remain the most common agents of canine and feline dermatophytosis in the South of England; continued clinical vigilance is required.

Abstract
BACKGROUND This study aimed to determine the impact of preoperative exposure to intravenous contrast for CT and the risk of developing postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery. METHODS This prospective, multicentre cohort study included adults undergoing gastrointestinal resection, stoma reversal or liver resection. Both elective and emergency procedures were included. Preoperative exposure to intravenous contrast was defined as exposure to contrast administered for the purposes of CT up to 7 days before surgery. The primary endpoint was the rate of AKI within 7 days. Propensity score-matched models were adjusted for patient, disease and operative variables. In a sensitivity analysis, a propensity score-matched model explored the association between preoperative exposure to contrast and AKI in the first 48 h after surgery. RESULTS A total of 5378 patients were included across 173 centres. Overall, 1249 patients (23·2 per cent) received intravenous contrast. The overall rate of AKI within 7 days of surgery was 13·4 per cent (718 of 5378). In the propensity score-matched model, preoperative exposure to contrast was not associated with AKI within 7 days (odds ratio (OR) 0·95, 95 per cent c.i. 0·73 to 1·21; P = 0·669). The sensitivity analysis showed no association between preoperative contrast administration and AKI within 48 h after operation (OR 1·09, 0·84 to 1·41; P = 0·498). CONCLUSION There was no association between preoperative intravenous contrast administered for CT up to 7 days before surgery and postoperative AKI. Risk of contrast-induced nephropathy should not be used as a reason to avoid contrast-enhanced CT.

Abstract
The Seventh Annual Deep Brain Stimulation (DBS) Think Tank held on September 8th of 2019 addressed the most current: (1) use and utility of complex neurophysiological signals for development of adaptive neurostimulation to improve clinical outcomes; (2) Advancements in recent neuromodulation techniques to treat neuropsychiatric disorders; (3) New developments in optogenetics and DBS; (4) The use of augmented Virtual reality (VR) and neuromodulation; (5) commercially available technologies; and (6) ethical issues arising in and from research and use of DBS. These advances serve as both "markers of progress" and challenges and opportunities for ongoing address, engagement, and deliberation as we move to improve the functional capabilities and translational value of DBS. It is in this light that these proceedings are presented to inform the field and initiate ongoing discourse. As consistent with the intent, and spirit of this, and prior DBS Think Tanks, the overarching goal is to continue to develop multidisciplinary collaborations to rapidly advance the field and ultimately improve patient outcomes.

Abstract
BACKGROUND Compared to horses and ponies, donkeys have increased degradation of dietary fiber. The longer total mean retention time of feed in the donkey gut has been proposed to be the basis of this, because of the increased time available for feed to be acted upon by enzymes and the gut microbiota. However, differences in terms of microbial concentrations and/or community composition in the hindgut may also underpin the increased degradation of fiber in donkeys. Therefore, a study was conducted to assess if differences existed between the fecal microbiota of pony, donkey and hybrids derived from them (i.e. pony × donkey) when fed the same forage diet. RESULTS Fecal community composition of prokaryotes and anaerobic fungi significantly differed between equine types. The relative abundance of two bacterial genera was significantly higher in donkey compared to both pony and pony x donkey: Lachnoclostridium 10 and 'probable genus 10' from the Lachnospiraceae family. The relative abundance of Piromyces was significantly lower in donkey compared to pony × donkey, with pony not significantly differing from either of the other equine types. In contrast, the uncultivated genus SK3 was only found in donkey (4 of the 8 animals). The number of anaerobic fungal OTUs was also significantly higher in donkey than in the other two equine types, with no significant differences found between pony and pony × donkey. Equine types did not significantly differ with respect to prokaryotic alpha diversity, fecal dry matter content or fecal concentrations of bacteria, archaea and anaerobic fungi. CONCLUSIONS Donkey fecal microbiota differed from that of both pony and pony × donkey. These differences related to a higher relative abundance and diversity of taxa with known, or speculated, roles in plant material degradation. These findings are consistent with the previously reported increased fiber degradation in donkeys compared to ponies, and suggest that the hindgut microbiota plays a role. This offers novel opportunities for pony and pony × donkey to extract more energy from dietary fiber via microbial mediated strategies. This could potentially decrease the need for energy dense feeds which are a risk factor for gut-mediated disease.

Abstract
ABSTRACT During July 2017, Texas public health officials noted an increase in the number of reported cyclosporiasis cases. They detected a cluster in the Houston metropolitan area that involved four locations of a Mediterranean restaurant chain, restaurant A. A case-control study was conducted among patrons of restaurant A to identify a common food vehicle among items containing fresh produce. In matched case-control ingredient-level analyses that included both probable and confirmed cases, consumption of green onions, red onions, tomatoes, and cabbage was significantly associated with illness. A substantial percentage of case patients reported consumption of green onions, and only green onions remained statistically significantly associated with illness, whether probable and confirmed cases were included in analyses (matched odds ratio: 11.3; 95% confidence interval: 2.5 to 104.7), or only confirmed cases were included in analyses (matched odds ratio: 17.6; 95% confidence interval: 2.5 to 775.7). These results provide evidence that green onions were the likely vehicle of infection. It was not possible to trace the green onions to their source due to the need to redirect public health resources to Hurricane Harvey response efforts in Texas. HIGHLIGHTS

Abstract
OBJECTIVE A library of intracranial electroencephalography (iEEG) from the normal human brain has recently been made publicly available (Frauscher et al., 2018). The library - which we term the Montreal Neurological Institute Atlas (MNIA) - comprises 30 hours of iEEG from over a hundred epilepsy patients. We present a Fourier spectrum-based model of low dimension that summarizes all of MNIA into a neurophysiological 'brain map'. METHODS Normalized amplitude spectra of the MNIA data were modelled as log-normal distributions around individual canonical Berger frequencies. The latter were concatenated to yield the composite spectrum with high accuracy. Key model parameters were color-coded into a visual representation on cortical surface models. RESULTS Each brain region has its own spectral characteristics that together yield a novel composite intracranial EEG brain map. CONCLUSIONS iEEG from normal brain regions can be accurately modelled with a small number of independent parameters. Our model is based in the canonical Berger bands and naturally suits clinical electroencephalography. SIGNIFICANCE Due to its applicability to iEEG from all sampled regions, the model suggests a certain universality to brain rhythm generation that is independent of precise cortical location. More generally, our results are a novel abstraction of resting cortical dynamics that may help diagnostics in epileptology, in addition to informing structure-function relationships in the field of human brain mapping.

Abstract
The stable fly Stomoxys calcitrans (L.) is a cosmopolitan biting fly of both economic and welfare concern, primarily as a result of its painful bite, which can cause blood loss, discomfort and loss of productivity in livestock. Between June and November in 2016 and May and December in 2017, Alsynite sticky-traps were deployed at four Donkey Sanctuary sites in southwest England, which experience recurrent seasonal biting fly problems. The aim was to evaluate the seasonal dynamics of the stable fly populations and the risk factors associated with abundance. In total, 19 835 S. calcitrans were trapped during the study period. In both years, abundance increased gradually over summer months, peaking in late August/September. There were no relationships between seasonally detrended abundance and any climatic factors. Fly abundance was significantly different between sites and population size was consistent between years at three of the four sites. The median chronological age, as determined by pteridine analysis of flies caught live when blood-feeding, was 4.67 days (interquartile range 3.8-6.2 days) in males and 6.79 days (interquartile range 4.8-10.4 days) in females; there was no significant, consistent change in age or age structure over time, suggesting that adult flies emerge continuously over the summer, rather than in discrete age-related cohorts. The data suggest that flies are more abundant in the vicinity of active animal facilities, although the strong behavioural association between flies and their hosts means that they are less likely to be caught on traps where host availability is high. The implications of these results for fly management are discussed.

Abstract
We have explored the relations between clinicopathological features and cervical lymph node metastases (LNM) in patients with cN0 squamous cell carcinoma (SCC) of the tongue, and developed and validated a nomogram for predicting the risk of their development. Clinical data on 230 patients with cN0 SCC of the tongue who had had primary extended excision and lymph node dissection of the neck were collected retrospectively. They were divided into a development cohort and a validation cohort in a 4:1 ratio. Logistic regression analysis was used to assess the risk factors of cervical LNM in patients in the development cohort, and a nomogram was established to predict the risk of such nodes. In the validation cohort, the predictive performance and compliance of the model were evaluated using the consistency index (C-index) and calibration curve, and the clinical value was evaluated by decision curve analysis. Of the 230 patients, 60 had cervical LNM, of which 60 were invaded (26%). Analysis of the development cohort showed that the site of the primary lesion, depth of invasion, size of the tumour, and histopathological grade were included in the prediction model, which was validated in the validation cohort. Consistency was high (C-index=0.846), calibration good, and it was clinically valuable. The nomogram could be used to predict the probability of occult cervical LNM before operation in patients with stage cN0 SCC of the tongue. It could also be used as a reference tool for dissection of cervical nodes and a communication tool between the doctor and the patient.

Abstract
The probabilities of locating peaks with a high relative peak-area uncertainty were determined empirically with nine types of peak-location software used in laboratories engaged in gamma-ray spectrometry measurements. It was found that it is not possible to locate peaks with a probability of 0.95, when they have a relative peak-area uncertainty in excess of 50%. Locating peaks at these relatively high peak-area uncertainties with a probability greater than 0.95 is only possible in the library-driven mode, where the peak positions are supposed a-priori. The deficiencies of the library-driven mode and the possibilities to improve the probabilities of locating peaks are briefly discussed.

Abstract
BACKGROUND The National Health Service in England advises hospitals collect data on hospital-onset diarrhoea (HOD). Contemporaneous data on HOD are lacking. AIM To investigate prevalence, aetiology and management of HOD on medical, surgical and elderly-care wards. METHODS A cross-sectional study in a volunteer sample of UK hospitals, which collected data on one winter and one summer day in 2016. Patients admitted ≥72 h were screened for HOD (definition: ≥2 episodes of Bristol Stool Type 5-7 the day before the study, with diarrhoea onset >48 h after admission). Data on HOD aetiology and management were collected prospectively. FINDINGS Data were collected on 141 wards in 32 hospitals (16 acute, 16 teaching). Point-prevalence of HOD was 4.5% (230/5142 patients; 95% confidence interval (CI) 3.9-5.0%). Teaching hospital HOD prevalence (5.9%, 95% CI 5.1-6.9%) was twice that of acute hospitals (2.8%, 95% CI 2.1-3.5%; odds ratio 2.2, 95% CI 1.7-3.0). At least one potential cause was identified in 222/230 patients (97%): 107 (47%) had a relevant underlying condition, 125 (54%) were taking antimicrobials, and 195 (85%) other medication known to cause diarrhoea. Nine of 75 tested patients were Clostridium difficile toxin positive (4%). Eighty (35%) patients had a documented medical assessment of diarrhoea. Documentation of HOD in medical notes correlated with testing for C. difficile (78% of those tested vs 38% not tested, P<0.001). One-hundred and forty-four (63%) patients were not isolated following diarrhoea onset. CONCLUSION HOD is a prevalent symptom affecting thousands of patients across the UK health system each day. Most patients had multiple potential causes of HOD, mainly iatrogenic, but only a third had medical assessment. Most were not tested for C. difficile and were not isolated.

Long S. Choosing Treatment for Dogs With Generalised Demodicosis – Isoxazolines or Imidacloprid and Moxidectin? VE 2019.

Abstract
<p><strong>PICO question</strong></p><p>In dogs with generalised demodicosis, are isoxazolines as effective as a combined formulation of imidacloprid and moxidectin at reducing mite count and the severity of associated clinical signs?</p><p><strong>Clinical bottom line</strong></p><p>Five single-blinded, randomised, positive control trials, most under laboratory conditions, directly compared the use of isoxazolines against moxidectin/imidacloprid to treat canine generalised demodicosis. All of them showed comparable efficacy of isoxazolines. Three different isoxazolines were studied with two routes of administration (oral and topical) and four different dosing frequencies of moxidectin/imidacloprid. This made the papers more challenging to compare however, the evidence provided is sufficient to support their use. All of these trials were sponsored by the manufacturers of their respective isoxazoline products which may bias the study design and reporting of results. It is worth noting that sarolaner (Simparica™, Zoetis UK) was licensed in the UK for the treatment of canine demodicosis in January 2018 and that in the UK the Cascade should be followed when prescribing treatments. The licensed use of isoxazolines in other countries is beyond the scope of this article and the reader is urged to check local regulatory body advice before prescribing the below medications.</p><br /> <img src="https://www.veterinaryevidence.org/rcvskmod/icons/oa-icon.jpg" alt="Open Access" /> <img src="https://www.veterinaryevidence.org/rcvskmod/icons/pr-icon.jpg" alt="Peer Reviewed" />

Quality Principles of App Description Texts and Their Significance in Deciding to Use Health Apps as Assessed by Medical Students: Survey Study. JMIR Mhealth Uhealth 2019; 7:e13375.

Abstract
Background Currently, there are no binding requirements for manufacturers prescribing which information must be included in the app descriptions of health apps. Objective The aim of this study was to investigate how medical students perceive a selection of quality principles, intended for usage decisions in the app context, and establish whether the information presented in a sample of app descriptions is perceived as sufficient for facilitating an informed usage decision. Methods A total of 123 students (mean age 24.2 years, SD 3.4) participating in a 6-week teaching module covering cardiology and pulmonology at the University of Göttingen (original enrollment 152 students, response rate 80.9%) were included. Students were asked to read 3 store description texts of cardiological or pneumological apps and initially assess whether the descriptions sufficed for a usage decision. Subsequently, they were queried on their perception of the relevance of 9 predefined quality principles, formulated for usage decisions. An appraisal of whether the app description texts contained sufficient information to satisfy these quality principles followed. By means of 20 guiding questions, participants were then asked to identify relevant information (or a lack thereof) within the descriptions. A reassessment of whether the description texts sufficed for making a usage decision ensued. A total of 343 complete datasets were obtained. Results A majority of the quality principles were described as “very important” and “important” for making a usage decision. When accessed via the predefined principles, students felt unable to identify sufficient information within the app descriptions in 68.81% (2124/3087) of cases. Notably, information regarding undesired effects (91.8%, 315/343), ethical soundness (90.1%, 309/343), measures taken to avert risks (89.2%, 306/343), conflicts of interest (88.3%, 303/343), and the location of data storage (87.8%, 301/343) was lacking. Following participants’ engagement with the quality principles, statistically significant changes in their assessment of whether the app descriptions sufficed for a usage decision can be seen—McNemar-Bowker test (3)=45.803919, P<.001, Cohen g=.295. In 34.1% (117/343) cases, the assessment was revised. About 3 quarters of changed assessments were seen more critically (76.9%, 90/117). Although, initially, 70% (240/343) had been considered “sufficient,” this rate was reduced to 54.2% (186/343) in the second assessment. Conclusions In a considerable number of app descriptions, participants were unable to locate the information necessary for making an informed usage decision. Participants’ sensitization to the quality principles led to changes in their assessment of app descriptions as a tool for usage decisions. Better transparency in app descriptions released by manufacturers and the exposure of users to quality principles could collectively form the basis for well-founded usage decisions.
