Abstract
Background Idiopathic pulmonary fibrosis (IPF) leads to progressive loss of lung function and mortality. Understanding mechanisms and markers of lung injury in IPF is paramount to improving outcomes for these patients. Despite the lack of systemic involvement in IPF, many analyses focus on identifying circulating prognostic markers. Using a proteomic discovery method followed by ELISA validation in multiple IPF lung compartments and cohorts we explored novel markers of IPF survival. Methods In our discovery analysis, agnostic label-free quantitative proteomics differentiated lung tissue protein expression based on survival trajectory (n=10). Following selection of the candidate pathway (neutrophil extracellular trap (NET) formation), we subsequently validated the presence of NETs in the IPF lung microenvironment using fully quantitative assays of known NET remnants in separate IPF cohorts (n=156 and n=52) with bronchoalveolar lavage fluid. We then assessed the correlation of these markers with baseline pulmonary function and survival. Results Discovery lung tissue proteomics identified NET formation as significantly associated with poor IPF survival. Using fully quantitative confirmatory tests for reproducibility we confirmed the presence of NET markers in IPF BALF and found significant correlations with worse pulmonary function in both cohorts (p<0.03 and p = 0.04 respectively). In the survival cohort, higher levels of NET markers predicted worse survival after adjusting for gender, age, and baseline physiologic severity (hazard ratio range: 1.79-2.19). Conclusions NET markers were associated with disease severity and worse survival in IPF. These findings suggest NET formation contributes to lung injury and decreased survival in IPF and may represent a potential therapeutic target.

"We want to change the system": a qualitative study on emergency medicine physician leadership. CAN J EMERG MED 2024; 26:266-270. [PMID: 38520497 DOI: 10.1007/s43678-024-00667-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2023] [Accepted: 01/31/2024] [Indexed: 03/25/2024]
Abstract
OBJECTIVE The significance of physician leadership to help transform the healthcare system has been increasingly discussed. This study looked at the qualities of emergency medicine (EM) physicians that support or inhibit their work as healthcare leaders. METHODS Through an iterative process of semi-structured interviews and then focus groups, we examined why EM physicians pursue leadership roles, the strengths they bring and the frustrations they encounter. Thematic analysis identified factors that facilitate and inhibit the work of EM physicians as they enter leadership roles. RESULTS These findings can be summarized in four key themes. (1) A desire to improve the wider health system was often a prime motivator for entering a leadership role. (2) EM physicians' clinical skills such as confident decision-making, relationship building through communication, and comfort with uncertainty supported their successful transition to leadership. (3) EM physician leaders perceived shiftwork as both a potential benefit and a challenge in their leadership role and felt it needed to be carefully managed to ensure personal wellness and success. And (4) participants were not driven to take on leadership positions by financial remuneration but stated that the discrepancy between EM clinical and leadership compensation was a point of stress. CONCLUSION As physician leadership is explored as a mechanism to support the healthcare system's success, this project provides insights into the realities experiences by EM physicians and considerations for healthcare professionals as they encourage physicians into leadership positions.

Abstract
Well North was a complex, multi-intervention health improvement programme spanning 10 sites across the North of England. The aim was to address inequalities by improving the health of the poorest fastest, increasing resilience and reducing levels of worklessness. The intention of the programme was for all sites to have freedom and flexibility to conduct different interventions reflecting local priorities. Evaluation ran concurrently with the programme, and an iterative approach was required to ensure constant feedback, allowing the programme to be adapted and improved as necessary. Realist methodology was chosen for evaluation, as it provides insight into what works, for whom and in what circumstances. Due to the complex nature of the programme and diverse approaches, it was necessary to adapt the methodology to meet the needs of the evaluation. The Evaluation Team utilized a range of qualitative and quantitative techniques within the context of a Rapid Cycle Evaluation framework. For each project, Contexts, Mechanisms and Outcomes (CMOs) were identified at three stages and were incorporated into the CMO configuration, leading to the development of a middle range theory. Validation and testing of theory took place at every stage. Realist methodology was the most appropriate existing method. However, it still necessitated modification.

Upscaling the remediation of acidic landscapes - the coastal floodplain prioritisation method. JOURNAL OF ENVIRONMENTAL MANAGEMENT 2023; 348:119260.

Abstract
Over 24 million hectares of the world's coastal floodplains are underlain by acid sulfate soils (ASS). Drainage of these sediments has led to widespread environmental degradation, raising serious health concerns. To date, onsite rehabilitation has been complicated by differing stakeholder priorities, with resources often allocated to sites with more vocal proponents rather than those exposed to more significant environmental impacts. To address this issue, this paper introduces the Coastal Floodplain Prioritisation (CFP) Method; a novel, data driven and spatially explicit multi-criteria assessment that ranks floodplain catchment areas according to their risk of transferring acidic drainage waters to an estuary. Results can be used to prioritise where remediation actions are likely to have the greatest benefit. The method was applied across six different estuaries in south-east Australia, with major field campaigns undertaken at each site. Within each estuary, the largest acid fluxes and impacts are identified with relevant mitigation measures provided. On a catchment scale, the results reflect the broader hydrogeomorphic characteristics of each estuary, including the historic acid formation conditions and recent anthropogenic drainage activities. Low-lying backswamps were identified as the highest risk zones within each estuary. These areas are also the most vulnerable to sea level rise. Reinstatement of tidal inundation to these backswamps effectively remediates acid sulfate soil discharges and provides a nature-based solution for adaptation to sea level rise with a range of co-benefits to encourage further investment.

Abstract
The LUX-ZEPLIN experiment is a dark matter detector centered on a dual-phase xenon time projection chamber operating at the Sanford Underground Research Facility in Lead, South Dakota, USA. This Letter reports results from LUX-ZEPLIN's first search for weakly interacting massive particles (WIMPs) with an exposure of 60 live days using a fiducial mass of 5.5 t. A profile-likelihood ratio analysis shows the data to be consistent with a background-only hypothesis, setting new limits on spin-independent WIMP-nucleon, spin-dependent WIMP-neutron, and spin-dependent WIMP-proton cross sections for WIMP masses above 9 GeV/c^{2}. The most stringent limit is set for spin-independent scattering at 36 GeV/c^{2}, rejecting cross sections above 9.2×10^{-48} cm at the 90% confidence level.

What about males? Exploring sex differences in the relationship between emotion difficulties and eating disorders. J Eat Disord 2022; 10:193. [PMID: 36514166 PMCID: PMC9749243 DOI: 10.1186/s40337-022-00715-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/28/2022] [Accepted: 11/29/2022] [Indexed: 12/15/2022] Open
Abstract
OBJECTIVE While eating disorders (EDs) are more commonly diagnosed in females, there is growing awareness that men also experience EDs and may do so in a different way. Difficulties with emotion processing and emotion regulation are believed to be important in EDs, but as studies have involved predominantly female samples, it is unclear whether this is also true for males. METHODS In a sample of 1604 participants (n = 631 males), we assessed emotion processing and emotion regulation in males with EDs (n = 109) and compared results to both females with EDs (n = 220) and males from the general population (n = 522). We also looked at whether emotion processing and emotion regulation difficulties predicted various aspects of eating psychopathology and whether this was moderated by sex. We assessed emotion processing with the Toronto Alexithymia Scale, emotion regulation with the Difficulties in Emotion Regulation Scale and the Emotion Regulation Questionnaire, and eating psychopathology with the Eating Disorder Examination Questionnaire. RESULTS We found that males with ED, like their female counterparts, suffered from emotion processing and emotion regulation deficits. We did find some sex differences, in that males with EDs tended to report more difficulties with their emotions as well as a more externally oriented thinking style compared to females with EDs. Difficulties with emotion processing and emotion regulation were strongly predictive of various aspects of eating psychopathology in both sexes. Importantly, we found that sex moderated the relationship between cognitive reappraisal and eating restraint. As such, low use of reappraisal was found to be associated with higher levels of restraint in females but not in males. DISCUSSION Difficulties with emotion processing and emotion regulation are associated with eating psychopathology in both males and females. Reappraisal was not found to be associated with reduced eating psychopathology in males, suggesting a cautious approach to interventions targeting this strategy. Research around explanatory mechanisms and interventions must adopt a broader viewpoint including those that are traditionally overlooked in EDs.

Abstract
Abstract
Introduction
This study aimed to investigate potential factors, including delay to surgical stabilisation, affecting mortality in older patients sustaining pelvic or acetabular (PA) fractures.
Method
A retrospective review of the Trauma Audit and Research Network (TARN) database was performed to identify older patients (aged 65 and over) sustaining PA fractures treated surgically in a UK Major Trauma Centre (MTC) between 2015 and 2019. Chi-squared and Fisher tests were used to compare 1-year mortality rates following operative intervention between patients treated within 72-hours and after 72-hours. Kaplan-Meier curves were used to visualise survival probability; significant predictors of survival were found using Cox proportional hazard models.
Results
Of 564 older patients with PA fractures, 70 met the inclusion criteria. The mean age was 76.1 years. The overall 1-year mortality rate was 20%. When patients were grouped by time to surgery, there was no statistically significant difference in 1-year mortality. Patients whose surgery was delayed more than 72-hours were more likely to have longer hospital stays (p = 0.002) or to have suffered from polytrauma (p = 0.025). Age, Charlson Co-morbidities Index and pre-op mobility status were associated with statistically significant differences in overall mortality. Patient gender, mechanism of injury, polytrauma and head injury were not significant predictors of mortality.
Conclusions
Surgical intervention within 72-hours of injury did not result in decreased mortality in older patients with PA fractures. The 1–year mortality rate between older PA fractures and hip fractures was comparable. Consideration should be given to a combined multidisciplinary approach to managing these patients.

Abstract
Background The wellbeing of patients with eating disorders is one of the priorities in the “bigger picture” of treatment for eating disorders. Sensory soothing strategies for sensory sensitivities are supportive tools which could be useful in day-care and inpatient clinical programmes. Methods Evaluation of multiple separate sensory wellbeing workshops consisting of psychoeducation and experiential components delivered in inpatient and intensive day-care services was performed. Participants’ self-report questionnaires were evaluated pre- and post-workshop. Additionally, patients’ comments and qualitative feedback was collected after completion of the workshop. Results There was strong evidence that self-reported awareness of sensory wellbeing, awareness of strategies to enhance sensory wellbeing, and confidence in managing sensory wellbeing increased after the workshops with positive qualitative feedback from participants. The feedback questionnaires highlighted that patients found the sessions useful and were able to use some of the skills and strategies they learned in the workshop. Conclusion This pilot work on sensory wellbeing workshops with a protocol-based format was feasible and beneficial for the patient group. Preliminary evidence suggests that delivery of similar workshops could be sensible in addition to treatment as usual in inpatient and day-care programmes.

Abstract
This study aimed to be the first to measure non-verbal communication in 25 eating disorder (ED) and 25 non-ED control participants during a naturalistic social interaction incorporating positive, negative and neutrally-valenced topics. The first hypothesis, that ED participants would show significantly reduced facial emotional expression than controls, was not supported. Supporting the second hypothesis of between-group differences in non-verbal behaviour, ED participants were less likely to lean in towards their interlocutor (d=.81) discussing negatively-valanced topics and were more likely to be positioned upright when discussing positively-valenced topics (d=.1.09) than controls. Irrespective of emotional valence, ED participants positioned their gaze on their interlocutor significantly less (d=.29) and spent more time looking down (d=.54), or away than controls (d=.63). ED participants moved their hands along with speech significantly less (d=.63) and gestured fewer real/hypothetical/imagined images/actions/objects) than controls (d=.57), irrespective of emotional valence. Instead, ED participants indicated discomfort in the social interaction, touching their nose (d=.89) or playing with their nails (d=.95) more often than controls. ED participants, regardless of emotional valence, showed significantly lowered electro-dermal activity (d=.60) than controls, supporting the exploratory hypothesis. People with EDs appear to make less efficient use of non-verbal communication than controls.

Abstract
AIM To examine the challenges healthcare teams face when treating people with type 1 diabetes and disordered eating and the strategies these teams have developed to facilitate effective treatment. METHODS Four semi-structured focus groups were conducted including two tertiary diabetes specialist teams and three tertiary eating disorders specialist teams between July and December 2018. Thematic analysis of the transcripts followed a six-phase process. RESULTS Twenty-nine experienced healthcare professionals (16 diabetes and 13 eating disorder specialists, 16±12 years' professional experience) were interviewed. The challenges identified in treating people with type 1 diabetes and disordered eating included subthemes the 'challenges specific to the healthcare professional' (feeling not competent enough and perceived emotional burden), 'challenges pertaining to patient factors' (e.g. difficulties with engaging in therapy) and 'challenges created by the healthcare system' (time pressure and staff shortage). Healthcare professionals expressed the need for a consensus on diagnosis and the definition of disordered eating in type 1 diabetes, as well as the need for training and educational resources specific to type 1 diabetes and disordered eating. Healthcare professionals gave practical examples of strategies of communication for better patient engagement and felt that multidisciplinary working in joint clinics with the other specialty were facilitators for recovery from disordered eating. CONCLUSIONS Healthcare professionals require multidisciplinary team support when treating people with type 1 diabetes and to improve their own competencies. The development of effective screening and assessment tools, educational resources and training for healthcare professionals, and developing multidisciplinary treatment pathways will be key to improving outcomes for their service users with type 1 diabetes and disordered eating.

Estimating the health loss due to poor engagement with cardiac rehabilitation in Australia. Int J Cardiol 2020; 317:7-12.

Abstract
BACKGROUND Cardiac rehabilitation (CR) programs are effective in reducing cardiovascular mortality and readmissions. However, most patients are denied the benefits of CR due to low referral rates. Of those patients referred, commencement rates vary from 28.4% to 60%. This paper quantifies the scale of health loss in Australia due to poor engagement with the program, and estimates how much public funding can be justifiably reallocated to address the problem. METHODS Economic decision modelling was undertaken to estimate the expected lifetime health loss and costs to Medicare. Key parameters were derived from Australian databases, CR registries and meta-analyses. Population health gains associated with uptake rates of 60%, and 85% were calculated. RESULTS CR was associated with a 99.9% probability of being cost-effective, even at a cost-effectiveness threshold lower than conventionally applied. Importantly, an average of 0.52 years of life expectancy are lost due to national uptake being below 60% achieved in some best performing programs in Australia, equivalent to 0.28 quality adjusted life years. The analysis indicates that $12.9 million/year could be justifiably reallocated from public funds to achieve a national uptake rate of 60%, while maintaining cost-effectiveness of CR due to the large health gains that would be expected. CONCLUSION CR is a cost-effective service for patients with coronary heart disease. In Australia, less than a third of patients commence CR, potentially resulting in avoidable patient harm. Additional investment in CR is vital and should be a national priority as the health gains for patients far outweigh the costs.

Abstract
BACKGROUND Despite the growing interest in the involvement of decision-making under conditions of risk in the onset of eating disorders in adolescence, no studies have investigated how the development of decision-making across that period may influence such a risk. Using data from the Millennium Cohort Study this study explored whether changes in performance on the Cambridge Gambling Task (CGT) between age 11 and age 14 were associated with presence of eating disorder (ED) symptoms at age 14. METHODS Latent class analysis was used to identify groups with distinct profiles based on their responses to questions investigating eating and dieting at age 14. CGT change scores were used as predictors of latent class membership in a logistic regression while accounting for confounders. RESULTS In our sample of 11,303 participants, the best class solution was a two-class one reflecting high and low risk for ED symptoms. Higher risk-taking scores and lower quality of decision-making scores at age 11 were associated with increased odds of belonging to the high-risk group at age 14. Risk-taking was reduced from age 11 to age 14, but a smaller reduction was associated with a higher probability of being in the higher risk group at age 14. The change over time in the other CGT measures was not associated with risk for ED symptoms. CONCLUSIONS Atypical change in risk-taking from early to middle adolescence may be implicated in the risk of ED symptoms in middle adolescence. These results should be replicated in clinical samples.

Abstract
General practice is often a patient’s first point of contact with the health system and the gateway to specialist services. In Australia, different aspects of the health system are managed by the Commonwealth Government and individual state / territory governments. Although there is a long history of research using administrative data in Australia, this split in the management and funding of services has hindered whole-system research. Additionally, the administrative data typically available for research are often collected for reimbursement purposes and lack clinical information. General practices collect a range of patient information including diagnoses, medications prescribed, results of pathology tests ordered and so on. Practices are increasingly using clinical information systems and data extraction tools to make use of this information. This paper describes approaches used on several research projects to access clinical, as opposed to administrative, general practice data which to date has seen little use as a resource for research. This information was accessed in three ways. The first was by working directly with practices to access clinical and management data to support research. The second involved accessing general practice data through collaboration with Primary Health Networks, recently established in Australia to increase the efficiency and effectiveness of health services for patients. The third was via NPS MedicineWise’s MedicineInsight program, which collects data from consenting practices across Australia and makes these data available to researchers. We describe each approach including data access requirements and the advantages and challenges of each method. All approaches provide the opportunity to better understand data previously unavailable for research in Australia. The challenge of linking general practice data to other sources, currently being explored for general practice data, is discussed. Finally, we describe some general practice data collections used for research internationally and how these compare to collections available in Australia.

Abstract
Background : In Europe, over 70% of the population live in urban areas (UAs). Most international comparative health research is done using national level data, as reliable and comparable urban data are often unavailable or difficult to access. This study aims to investigate whether population health is different in UAs compared with their corresponding countries. : Routinely available health-related data were collected by the EURO-URHIS 2 project, for 10 European countries and for 24 UAs within those countries. National and UA level data for 11 health indicators were compared through the calculation of relative difference, and geographical patterns within Europe were investigated using the Mann Whitney U test. Linear regression modelling was used to adjust for population density, gross domestic product and urbanicity. : In general, the urban population in Eastern Europe is less healthy than the Western European urban population. However, people in Eastern Europe have significantly better broad health outcomes in UAs as compared with the corresponding country as a whole, whereas people in Western Europe have generally worse broader health outcomes in UAs. : For most European countries and UAs that were investigated, the national level health status data does not correspond with the health status at UA level. In order to identify health problems in UAs and to provide information for local health policy, health monitoring and international benchmarking should also be conducted at the local level.

Comparative tests of the role of dewlap size in Anolis lizard speciation. Proc Biol Sci 2017; 283:rspb.2016.2199.

Abstract
Phenotypic traits may be linked to speciation in two distinct ways: character values may influence the rate of speciation or diversification in the trait may be associated with speciation events. Traits involved in signal transmission, such as the dewlap of Anolis lizards, are often involved in the speciation process. The dewlap is an important visual signal with roles in species recognition and sexual selection, and dewlaps vary among species in relative size as well as colour and pattern. We compile a dataset of relative dewlap size digitized from photographs of 184 anole species from across the genus' geographical range. We use phylogenetic comparative methods to test two hypotheses: that larger dewlaps are associated with higher speciation rates, and that relative dewlap area diversifies according to a speciational model of evolution. We find no evidence of trait-dependent speciation, indicating that larger signals do not enhance any role the dewlap has in promoting speciation. Instead, we find a signal of mixed speciational and gradual trait evolution, with a particularly strong signal of speciational change in the dewlaps of mainland lineages. This indicates that dewlap size diversifies in association with the speciation process, suggesting that divergent selection may play a role in the macroevolution of this signalling trait.

Abstract
Chip based particle sensing using 3D capillary fill microfluidics integrated with monolithically integrated lasers and photodetectors is used to demonstrate the feasibility of true chip scale photonic measurements of fluids. The approach is scalable and manufactured using industry standard compound semiconductor fabrication tools. The need for fluid speed regulation via external pumps is removed by measuring local particle velocity at the point of interrogation and particle position within the fluid flow is derived from multiple time resolved forward scattered light signals. Particle size discrimination of 10 and 15 μm polystyrene microbeads is used as an example.

"Safe Foods" or "Fear Foods": the implications of food avoidance in college students from low- and middle-income countries. Eat Weight Disord 2017; 22:407-419.

Abstract
PURPOSE The primary objective of this study was to explore if self-reported food avoidance (fats, carbohydrates and protein) exists among college students in low- and middle-income countries (LMICs) and its relationship with body mass index (BMI), dieting, mood/anxiety symptoms, physical activities and general health knowledge. METHODS This study is a subset (N = 6096) of a larger 26 LMICs cross-sectional survey, which consisted of 21,007 college students. We ascertained socio-demographic information, food avoidance, physical activities, dieting behaviours, depressive and PTSD symptoms, and recorded anthropometric measurements. Chi-square analyses assessed the relationship between predictor variables and food categories eliminated from participants' diet. Multiple logistic regression assessed if food avoidance predicts outcome variables such as binge drinking, high physical activity, being underweight, exhibiting significant depressive and PTSD symptoms. RESULTS Food avoidance exists in as many as one-third of college students in low- and middle-income countries, with this being more likely in persons who are trying to lose weight whether by dieting or otherwise. Food avoidance was associated with higher BMI, depressive symptoms, and high intensity exercises, as well as the level of health knowledge influencing the types of food avoided. A significant difference was noted between lower middle-income and upper middle-income countries with respect to the foods they avoided. CONCLUSION Despite being knowledgeable about health-related behaviours, we found that college students in our sample were not that different from those in developed countries and may be influenced by a similar advice given by non-experts about macronutrients. These results hold implications for intervention programmes and policy makers. LEVEL OF EVIDENCE Level V, descriptive cross-sectional survey.

Abstract
mHealth is transforming health care, yet few studies have evaluated patient and carer perceptions of the use of smartphones at the patient bedside. In this study, 70 patients and carers answered a short survey on health professionals' use of mobile devices. Half the participants were tolerant of doctors using such devices if it was work-related; others believed it was a distraction and not beneficial to patient care. Changes in practice and patient education may be needed to enable effective use of mobile devices in health.

Abstract
The aim of this study was to decide whether shoulder pain in stroke is a marker of severity, or an independent predictor of poor outcome. The study was prospective observational in design from consecutive admissions. Acute medical and geriatric wards in three district hospitals provided the setting, and the subjects were 76 patients acutely admitted to hospital with a first stroke. The main outcomes measured were length of stay in hospital, Barthel Index, Frenchay Arm Test, Motricity Index and discharge placement. After controlling for other indicators of stroke severity, shoulder pain on movement was the most important predictor of poor recovery of arm power and function, and an important contributor to length of stay in hospital. Urinary incontinence was the strongest indicator of length of stay and Barthel Index scores. Patients with subluxation and malalignment of the shoulder fared much more poorly than those with normal shoulder alignment. The results concluded that shoulder pain appears to influence outcome of stroke independent of severity. We recommend that this symptom receive careful attention.

Detection of late radiation damage on left atrial fibrosis using cardiac late gadolinium enhancement magnetic resonance imaging. Adv Radiat Oncol 2016; 1:106-114.

Abstract
Purpose This is a proof-of-principle study investigating the feasibility of using late gadolinium enhancement magnetic resonance imaging (LGE-MRI) to detect left atrium (LA) radiation damage. Methods and materials LGE-MRI data were acquired for 7 patients with previous external beam radiation therapy (EBRT) histories. The enhancement in LA scar was delineated and fused to the computed tomography images used in dose calculation for radiation therapy. Dosimetric and normal tissue complication probability analyses were performed to investigate the relationship between LA scar enhancement and radiation doses. Results The average LA scar volume for the subjects was 2.5 cm3 (range, 1.2-4.1 cm3; median, 2.6 cm3). The overall average of the mean dose to the LA scar was 25.9 Gy (range, 5.8-49.2 Gy). Linear relationships were found between the amount of radiation dose (mean dose) (R2 = 0.8514, P = .03) to the LA scar-enhanced volume. The ratio of the cardiac tissue change (LA scar/LA wall) also demonstrated a linear relationship with the level of radiation received by the cardiac tissue (R2 = 0.9787, P < .01). Last, the normal tissue complication probability analysis suggested a dose response function to the LA scar enhancement. Conclusions With LGE-MRI and 3-dimensional dose mapping on the treatment planning system, it is possible to define subclinical cardiac damage and distinguish intrinsic cardiac tissue change from radiation induced cardiac tissue damage. Imaging myocardial injury secondary to EBRT using MRI may be a useful modality to follow cardiac toxicity from EBRT and help identify individuals who are more susceptible to EBRT damage. LGE-MRI may provide essential information to identify early screening strategy for affected cancer survivors after EBRT treatment.

Abstract
The effective communication of risk, which is central to the process of consent, can be difficult, and can be hard for patients to understand. We introduce the potential utility of the micromort, a unit of risk defined as a one-in-a-million chance of sudden death, which allows clinicians to compare the risks of an intervention with those of different activities, making them easier to understand.

Abstract
The majority of human pathogens are zoonotic and rodents play an important role as reservoirs of many of these infectious agents. In the case of vector-borne pathogens, rodent reservoirs not only act as a source of infection for vectors but also serve as hosts for the vectors themselves, supporting their populations. Current data on rodent-ectoparasite relationships is limited in Saudi Arabia, however, this is needed to assess disease risk and the relative importance of different hosts for the maintenance of vector-borne pathogen cycles. In order to provide baseline data for the region that could be used to assess zoonotic disease risk, we collected and identified 771 ectoparasite specimens (ticks, fleas and mites) from 161 rodents at two wildlife research centres in Saudi Arabia and discuss our results in the context of possible zoonotic disease risk based on the hosts and vectors present.

Abstract
The importance of the right ventricle (RV) in pulmonary arterial hypertension (PAH) has been gaining increased recognition. This has included a reconceptualization of the RV as part of an RV-pulmonary circulation interrelated unit and the observation that RV function is a major determinant of prognosis in PAH. Noninvasive imaging of RV size and function is critical to the longitudinal management of patients with PAH, and continued understanding of the pathophysiology of pulmonary vascular disease relies on the response of the RV to pulmonary vascular remodeling. Echocardiography, in particular the newer echocardiographic measurements and techniques, allows easy, readily accessible means to assess and follow RV size and function.

Abstract
OBJECTIVE To identify predictors of severe retinopathy of prematurity (ROP) in a large population-based cohort and to examine risk-adjusted variations across units. STUDY DESIGN Retrospective analysis of Canadian Neonatal Network data on neonates with birth weight <1500 g who were screened for ROP between 2003 and 2010. Characteristics of infants with and without ROP were compared and a risk-adjusted model for severe ROP was developed. Rates of severe ROP were compared between sites. RESULTS 1163 of 9187 (12.7%) infants developed severe ROP. Lower gestational age, male sex, small for gestational age, patent ductus arteriosus, late onset sepsis, more than two blood transfusions, inotrope use, and outborn status were associated with an increased risk of severe ROP. Severe ROP rates varied significantly between units. CONCLUSION Younger, smaller and sicker male infants had higher adjusted risks of severe ROP and rates varied significantly among sites.
