Abstract
Hospital acquired infections stemming from contaminated reusable medical devices are of increasing concern. This issue is exaggerated with the introduction of complex medical devices like endoscopes and robotic instrumentation. Although medical device manufacturers validate their cleaning instructions for use, evidence in the literature demonstrates that effective device processing is not being performed consistently within sterile processing departments in clinical settings. The result is increased risks to patient safety. As a solution to this problem, focused one-on-one training increases compliance to the medical device manufacturer's processing instruction. However, often this is not a practical solution for the volume of healthcare staff responsible for device processing activities. This constitutes the first paper to address the blended use of educational and digital technologies to address these challenges and as a result inform safety and sustainability for the medical device sector. Cognitive learning theory is an evidence-based framework for learning. It supports the use of immersive educational experiences using emerging extended reality technologies (e.g., virtual or augmented reality) to increase learning comprehension. The delivery of educational content via these technologies provides an innovative option for repeatable leaning and training outcomes. The motivation is to decrease patient risk of contaminated reusable medical devices. The proposed approach while primary motivated by safety can also enhance sustainability and efficiency enabled by artificial intelligence and robotic instrumentation.

Abstract
Abstract
Introduction/Objective
With rising healthcare costs in the United States, there has been a push for lab stewardship to improve the quality of patient care while reducing costs. To optimize the use of clinical laboratory testing, the ASCP working with other medical specialty organizations, developed the Choosing Wisely Campaign to promulgate evidence-based guidelines to optimize clinical laboratory testing.
Methods/Case Report
We examined adherence to three Choosing Wisely guidelines over a four-year period (2017- 2020), through queries of internal cost accounting databases to return aggregate volumes as well as variable and total costs at three large academic health systems. We measured concurrent orders for: 1) erythrocyte sedimentation rate (ESR) with C-reactive protein (CRP), 2) serum/plasma amylase with lipase, and 3) free thyroxine (FT4) and/or total triiodothyronine (TT3) with thyroid stimulating hormone (TSH) when the TSH is within the reference range (using an frequency estimate of 85% based on other studies). We also examined another guideline for concurrent orders for serum aldolase with creatine kinase (CK). We also quantified aggregate variable costs for the non-recommended test in each Choosing Wisely guideline (amylase, ESR, FT4 and/or TT3), and for serum aldolase when ordered with CK.
Results (if a Case Study enter NA)
Over the four-year period, there were 322,853 unnecessary tests based on these four guidelines (120,587 ESR and CRP, 30,444 amylase and lipase, 164,818 FT4 and/or TT3 with TSH, and 7,004 aldolase). Overall, unnecessary testing decreased between 2017 and 2020 for amylase with lipase, remained essentially unchanged for aldolase, and increased for the other two test guideline scenarios. The largest changes were concurrent orders for amylase and lipase at one health system (38% decrease), and orders for TT3 with a normal TSH result at another health system (324% increase). The four-year variable cost of these unnecessary tests was $1,215,309 ($303,827 mean annual cost), resulting in potential annual variable cost savings of $101,276 for each health system for the four guidelines we examined. Variable costs for unnecessary testing increased by 16.5% ($45,571) over the four-year period.
Conclusion
Guideline-based unnecessary testing remains as a target to improve laboratory diagnostic testing. There is potential to realize significant achievable cost savings if guidelines are implemented and maintained.

Abstract
Abstract
Aim
A group and hold (G&H) forms part of the pretransfusion compatibility testing and is commonly requested in anticipation of a possible blood transfusion. Requests made in the context of elective procedures with a low transfusion probability, such as a mastectomy, are associated with added financial burden and increases workload in a healthcare system. This audit aims to analyse the cost-benefit associated with the routine request for a preoperative G&H in patients undergoing mastectomies.
Method
A total of 100 patients undergoing mastectomies from the period of September 2019 to October 2020 were included in the audit. Data regarding blood order requests, units of blood transfused, perioperative haemoglobin and the type of mastectomy (right, left or bilateral) were collected.
Results
All patients had a routine G&H as part of their preoperative assessment. The average age in this cohort was 60.3. Right-sided mastectomy was the commonest procedure in this cohort (N = 52). The average preoperative haemoglobin was 13.0g/dL. 2/100 patients received post-operative blood transfusions. The transfusion probability in this cohort was 2%. Only 15% of the cohort had a post-operative haemoglobin level checked. The average drop in haemoglobin in this cohort was 2.3g/dL.
Conclusions
This audit demonstrates the low prevalence of blood transfusions in patients undergoing mastectomies, consistent with current literature. The projected cost savings associated with selective requests for G&H are significant. However, the implementation of a safe and targeted blood ordering approach in patients with high bleeding risks will require a validated stratification system.

Abstract
Schools are important environments for promotion of healthy behaviors to reduce childhood obesity; however, many barriers prevent schools from sustaining wellness programs. The goal of the Healthy Champions program was to assist schools with identifying areas for improvement through a nutrition and activity-focused assessment, and delivery of a customized score report and welcome kit with materials to promote healthful behavior change. In this study, we aimed to describe participation and assessment results for this program across a five-year period. Enrollment in the Healthy Champions program was open to private and public K-12 schools across Pennsylvania beginning in 2013. School staff completed an assessment that scored aspects of the wellness environment and was used to enroll schools in the program. Schools were awarded star status (0–5) based upon responses and provided a tailored response to improve ratings, and with re-enrollment, became a simple way for schools to track progress. From 2013 to 2018, 592 schools enrolled for at least one year, representing 58 out of 67 counties (87%) in Pennsylvania. Mean star status at baseline was 2.89 out of 5; however, schools enrolled for multiple years (51%) saw significant improvement in star status, independent of school size and rural/urban status.

Abstract
Adherence to a Mediterranean Diet (MedDiet) is inversely associated with sarcopenia. The aim of this study was to examine the association between adherence to a MedDiet and sarcopenic symptomology in obese older adults. For confirmation of sarcopenia, low appendicular skeletal muscle (ASM: males, ≤7.25kg/m2; females, ≤5.5kg/m2) accompanied low handgrip strength (males, ≤30kg; females, ≤20kg) or low physical performance (Short Physical Performance Battery [SPPB]: ≤8; or gait speed: ≤0.8m/sec). Adherence to a MedDiet was determined using the Mediterranean Diet Adherence Screener (MEDAS). Sixty-five older adults were included. Adherence to a MedDiet was not associated with a decreased risk of sarcopenic symptomology (SPPB: OR = 0.20; 95% CI: 0.01-3.1; P = 0.234; Muscle strength: OR = 1.81; 95% CI: 0.32-10.15; P = 0.499; Gait speed: OR = 0.58; 95% CI: 0.13-2.50; P = 0.468). Future research should investigate whether a Mediterranean-style intervention can prevent or improve sarcopenic symptomology, including in non-Mediterranean populations.

Abstract
Aims Accurate preoperative knowledge of tumour stage is important in preoperative planning at radical prostatectomy (RP). The aim of this study was to assess the predictive ability of multiparametric MRI for detecting pathological outcomes. Methods A retrospective review was performed of all patients who underwent RP over a 4 year period. Results Preoperative MRI was reported as showing T3 or T4 disease in 26(17.9%) out of 145 patients undergoing RP. Of these, 10(6.9%) had ECE (extra-capsular extension) and 1(0.7%) had SVI (seminal vesicle invasion) on final histology. The sensitivity and specificity of MRI for detecting ECE were 27.3% and 87.6%, respectively. The sensitivity and specificity of MRI for detecting SVI were 11.1% and 97.8%, respectively. The positive predictive values for determining ECE and SVI were 45.5% and 25%, respectively and negative predictive values were 75.9% and 94.4%. Conclusion MRI has good specificity but poor and heterogeneous sensitivity for predicting T3 disease in RP specimen.

Abstract
We report two patients who presented with extensive aneurysmal disease, in association with minimal external physical signs. Patient 1 remained genetically undiagnosed despite multiple structural, biochemical and genetic investigations. He made a good recovery following surgery for popliteal and left axillary artery aneurysms. Patient 2 was diagnosed with vascular type Ehlers-Danlos syndrome, associated with a high degree of tissue and blood vessel fragility, and is being managed conservatively. Early multidisciplinary assessment of such patients facilitates accurate diagnosis and management.

Abstract
Levels of physical inactivity, a major contributor to burden of disease, are high in many countries. Some preliminary research suggests that circulating lutein concentrations are associated with high levels of physical activity (PA). We aimed to assess whether the intake of lutein-containing foods, including vegetables and eggs, is associated with levels of PA in two studies conducted in different countries. Dietary data and PA data collected from participants in two cross-sectional studies: the Maine-Syracuse Longitudinal Study (MSLS), conducted in Central New York, USA (n = 972), and the Observation of Cardiovascular Risk Factors in Luxembourg Study (ORISCAV-LUX) (n = 1331) were analyzed. Higher intakes of lutein containing foods, including green leafy vegetables, were associated with higher levels of PA in both study sites. Increasing the consumption of lutein-rich foods may have the potential to impact positively on levels of PA. This needs to be further explored in randomized controlled trials.

Abstract
We investigated a new intramedullary locking nail that allows the distal interlocking screws to be locked to the nail. We compared fixation using this new implant with fixation using either a conventional nail or a locking plate in a laboratory simulation of an osteoporotic fracture of the distal femur. A total of 15 human cadaver femora were used to simulate an AO 33-A3 fracture pattern. Paired specimens compared fixation using either a locking or non-locking retrograde nail, and using either a locking retrograde nail or a locking plate. The constructs underwent cyclical loading to simulate single-leg stance up to 125 000 cycles. Axial and torsional stiffness and displacement, cycles to failure and modes of failure were recorded for each specimen. When compared with locking plate constructs, locking nail constructs had significantly longer mean fatigue life (75 800 cycles (sd 33 900) vs 12 800 cycles (sd 6100); p = 0.007) and mean axial stiffness (220 N/mm (sd 80) vs 70 N/mm (sd 18); p = 0.005), but lower mean torsional stiffness (2.5 Nm/° (sd 0.9) vs 5.1 Nm/° (sd 1.5); p = 0.008). In addition, in the nail group the mode of failure was either cut-out of the distal screws or breakage of nails, and in the locking plate group breakage of the plate was always the mode of failure. Locking nail constructs had significantly longer mean fatigue life than non-locking nail constructs (78 900 cycles (sd 25 600) vs 52 400 cycles (sd 22 500); p = 0.04). The new locking retrograde femoral nail showed better stiffness and fatigue life than locking plates, and superior fatigue life to non-locking nails, which may be advantageous in elderly patients.

Abstract
Salmonella Typhimurium DT8 was a very rare cause of human illness in Ireland between 2000 and 2008, with only four human isolates from three patients being identified. Over a 19-month period between August 2009 and February 2011, 34 confirmed cases and one probable case of Salmonella Typhimurium DT8 were detected, all of which had an MLVA pattern 2-10-NA-12-212 or a closely related pattern. The epidemiological investigations strongly supported a linkbetween illness and exposure to duck eggs. Moreover, S. Typhimurium with an MLVA pattern indistinguishable (or closely related) to the isolates from human cases, was identified in 22 commercial and backyard duck flocks, twelve of which were linked with known human cases. A range of control measures were taken at farm level, and advice was provided to consumers on the hygienic handling and cooking of duck eggs. Although no definitive link was established with a concurrent duck egg-related outbreak of S. Typhimurium DT8 in the United Kingdom, it seems likely that the two events were related. It may be appropriate for other countries with a tradition of consuming duck eggs to consider the need for measures to reduce the risk of similar outbreaks.

Abstract
A growing body of observational research suggests that dairy consumption may have a beneficial effect on the metabolic syndrome (MetS). MetS is a clustering of cardiometabolic risk factors within an individual that carries with it an increased risk of developing cardiovascular disease. A systematic search of electronic databases identified cross-sectional studies (n = 10) and prospective cohort studies (n = 3) that assessed dairy intake in relation to MetS. The quality of the included studies was assessed based on study methodology, measurement and reporting of dietary intake, use of standardized MetS diagnostic criteria and statistical analysis. Dairy intake was inversely associated with incidence or prevalence of MetS in seven out of 13 studies. Three studies found no association between dairy and MetS. Three studies reported mixed relationships between specific dairy foods and MetS. The majority of studies suggested a potential benefit of dairy consumption on the risk of having MetS, but methodological differences, potential biases and other limitations in the studies conducted prevent conclusions to be drawn. Future randomized controlled trials are needed to confirm the effect of dairy consumption on MetS.

Abstract
The authors previously reported on an active, young male with normal coronaries who sustained an acute myocardial infarction (AMI). The acute cause was a coronary thrombus; however, the cause of this thrombus and a definitive diagnosis remained elusive for 18 months until a new series of events, including symptoms of breathlessness, dizziness and collapse led to acute hospital admission. CT scan revealed numerous deep venous thromboses in the right leg and bilateral pulmonary emboli (PE). Acute pharmacological thrombolysis eliminated breathlessness and significantly reduced the risk of mortality. Clinical consensus suggests a coagulopathy, requiring indefinite treatment with Warfarin. In young individuals presenting with AMI, lifestyle, personal, family and clinical history should be considered and coronary artery disease should not be assumed until further tests have eliminated coagulopathy. In those presenting with breathlessness and a history which includes AMI, a CT scan is indicated to eliminate concerns of venous thromboembolism generally and PE specifically where untreated survival times are short.

Abstract
METHODS The clinical phenotype of 45 genetically confirmed McArdle patients is described. RESULTS In the majority of patients (84%), the onset of symptoms was from early childhood but diagnosis was frequently delayed until after 30 years of age. Not all patients could recognise a second wind although it was always seen with exercise assessment. A history of myoglobinuria was not universal and episodes of acute renal failure had occurred in a minority (11%). The condition does not appear to adversely affect pregnancy and childbirth. Clinical examination was normal in most patients, muscle hypertrophy was present in 24% and mild muscle wasting and weakness were seen only in patients over 40 years of age and was limited to shoulder girdle and axial muscles. The serum creatine kinase was elevated in all but one pregnant patient. Screening for the mutations pArg50X (R50X) and pGly205Ser (G205S) showed at least one mutated allele in 96% of Caucasian British patients, with an allele frequency of 77% for pArg50X in this population. A 12 min walking test to evaluate patients is described. CONCLUSION The results demonstrated a wide spectrum of severity with the range of distance walked (195-1980 m); the mean distance walked was 512 m, suggesting significant functional impairment in most patients.

Abstract
BACKGROUND Development of betulinic acid derivatives for clinical use has been hampered by adverse pharmacological and physico-chemical characteristics of this class of compounds. We here present a novel semi-synthetic betulinic acid-derived drug candidate well suited for further clinical development. MATERIALS AND METHODS In vitro activity and mode of action of NVX-207 were determined using normal as well as cancer cell lines. Gene expression profiling was performed with Affymetrix U133 microarrays. NVX-207 binding partners were identified using a heterobifunctional chemical crosslinker system. Potential binding proteins were identified by matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) analysis. Clinical studies were conducted in canine cancer patients suffering from spontaneously arising pre-treated tumours. RESULTS NVX-207 showed anti-tumour activity (mean IC(50) = 3.5 microM) against various human and canine cell lines. NVX-207-induced apoptosis was associated with activation of the intrinsic apoptotic pathway via cleavage of caspases -9, -3, -7 and of poly (ADP-ribose) polymerase (PARP). Global gene expression profiling demonstrated regulation of genes associated with lipid metabolism, most notably an upregulation of genes coding for insulin-induced gene 1 (Insig-1), low-density lipoprotein receptor (LDL-R) and of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA). NVX-207 bound to apolipoprotein A-I, a major regulator of lipid metabolism and cholesterol transport. A phase I/II study in dogs suffering from naturally occurring cancer receiving local treatment of NVX-207 (10 mg mL(-1)) showed excellent clinical responses including a complete remission in so far 5/5 treated animals. CONCLUSIONS NVX-207 is well tolerated and has significant anti-cancer activity in vitro and in vivo in dogs with treatment-resistant malignancies.

Abstract
Since 1994, Irish cattle have been exposed to greater risks of acquiring Mycobacterium avium subspecies paratuberculosis (MAP) infection as a consequence of the importation of over 70,000 animals from continental Europe. In recent years, there has been an increase in the number of reported clinical cases of paratuberculosis in Ireland. This study examines the prevalence of factors that promote the introduction and within-herd transmission of Mycobacterium avium subspecies paratuberculosis (MAP) on selected Irish dairy farms in the Cork region, and the association between these factors and the results of MAP screening tests on milk sock filter residue (MFR). A total of 59 dairy farms, selected using non-random methods but apparently free of endemic paratuberculosis, were enrolled into the study. A questionnaire was used to collect data about risk factors for MAP introduction and transmission. The MFR was assessed on six occasions over 24 months for the presence of MAP, using culture and immunomagnetic separation prior to polymerase chain reaction (IMS-PCR). Furthermore, blood samples from all entire male and female animals over one year of age in 20 herds were tested by ELISA. Eighteen (31%) farms had operated as closed herds since 1994, 28 (47%) had purchased from multiple sources and 14 (24%) had either direct or indirect (progeny) contact with imported animals. Milk and colostrum were mixed on 51% of farms, while 88% of farms fed pooled milk. Thirty (51%) herds tested negative to MFR culture and IMS-PCR, 12 (20%) were MFR culture positive, 26 (44%) were IMS-PCR positive and seven (12%) were both culture and IMS-PCR positive. The probability of a positive MFR culture was significantly associated with reduced attendance at calving, and with increased use of individual calf pens and increased (but not significantly) if mulitiple suckling was practised. There was poor agreement between MFR culture and MFR IMS-PCR results, but moderate agreement between MFR culture and ELISA test results. This study highlights a lack of awareness among Irish dairy farmers about the effect of inadequate biosecurity on MAP introduction. Furthermore, within-herd transmission will be facilitated by traditional calf rearing and waste management practices. The findings of viable MAP in the presence of known transmission factors in non-clinically affected herds could be a prelude to long-term problems for the Irish cattle and agri-business generally.
