Abstract
Understanding universal aspects of quantum dynamics is an unresolved problem in statistical mechanics. In particular, the spin dynamics of the one-dimensional Heisenberg model were conjectured as to belong to the Kardar-Parisi-Zhang (KPZ) universality class based on the scaling of the infinite-temperature spin-spin correlation function. In a chain of 46 superconducting qubits, we studied the probability distribution of the magnetization transferred across the chain's center, [Formula: see text]. The first two moments of [Formula: see text] show superdiffusive behavior, a hallmark of KPZ universality. However, the third and fourth moments ruled out the KPZ conjecture and allow for evaluating other theories. Our results highlight the importance of studying higher moments in determining dynamic universality classes and provide insights into universal behavior in quantum systems.

Abstract
OBJECTIVES The objective was to report and compare the complications and recurrence rates of urethral prolapse in dogs when treated with urethropexy, resection and anastomosis or a combined surgical technique. STUDY DESIGN Retrospective study. MATERIALS AND METHODS A total of 86 dogs were identified from the medical records of 10 veterinary referral hospitals from February 2012 and October 2022. Dogs were included if they underwent surgery for a urethral prolapse at first presentation. Complications were classified as minor or major based on the necessity of further surgical intervention. Complications leading to death were also considered major complications. RESULTS Seventy-nine dogs were included, urethropexy (n=44), resection and anastomosis (n=27) and a combined surgical technique (n=8). Minor complications were identified in 41 of 79 dogs (51.9%): urethropexy 19 of 44 (43.2%), resection and anastomosis 18 of 27 (66.6%) and a combined surgical technique four of eight (50%). Major complications occurred in 23 dogs (29.1%), of which 21 were recurrence (26.6%). Recurrence occurred in 17 of 44 dogs following a urethropexy (38.6%), three of 27 dogs following resection and anastomosis (11.1%) and one of eight dogs treated with a combined surgical technique (12.5%). Recurrence of a urethral prolapse was significantly more likely following urethropexy in comparison to resection and anastomosis. CLINICAL SIGNIFICANCE Resection and anastomosis was associated with a lower recurrence rate in comparison to urethropexy for the surgical treatment of urethral prolapse. Based on these results, we concluded that resection and anastomosis may be preferable to urethropexy for treatment of urethral prolapse at first presentation. Urethropexy, and resection and anastomosis combined surgical technique was associated with low recurrence rate; however, further studies will be needed to clarify if it provides any benefit over resection and anastomosis.

Abstract
The Royal College of Anaesthetists' 7th National Audit Project baseline survey assessed knowledge, attitudes, practices and experiences of peri-operative cardiac arrests among UK anaesthetists and Anaesthesia Associates. We received 10,746 responses, representing a 71% response rate. In-date training in adult and paediatric advanced life support was reported by 9646 (90%) and 7125 (66%) anaesthetists, respectively. There were 8994 (84%) respondents who were confident in leading a peri-operative cardiac arrest, with males more confident than females, but only 5985 (56%) were confident in leading a debrief and 7340 (68%) communicating with next of kin. In the previous two years, 4806 (46%) respondents had managed at least one peri-operative cardiac arrest, of which 321 (7%) and 189 (4%) of these events involved a child or an obstetric patient, respectively. Respondents estimated the most common causes of peri-operative cardiac arrest to be hypovolaemia, hypoxaemia and cardiac ischaemia, with haemorrhage coming fifth. However, the most common reported causes for the most recently attended peri-operative cardiac arrest were haemorrhage; (927, 20%); anaphylaxis (474, 10%); and cardiac ischaemia (397, 9%). Operating lists or shifts were paused or stopped after 1330 (39%) cardiac arrests and 1693 (38%) respondents attended a debrief, with 'hot' debriefs most common. Informal wellbeing support was relatively common (2458, 56%) and formal support was uncommon (472, 11%). An impact on future care delivery was reported by 196 (4%) anaesthetists, most commonly a negative psychological impact. Management of a peri-operative cardiac arrest during their career was reported by 8654 (85%) respondents. The overall impact on professional life was more often judged positive (2630, 30%) than negative (1961, 23%), but impact on personal life was more often negative.

Abstract
Despite increasing use of in vitro models that closely resemble in vivo human biology, their application in understanding downstream effects of airway toxicity, such as inflammation, are at an early stage. In this study, we used various assays to examine the inflammatory response induced in MucilAir™ tissues and A549 cells exposed to three products known to induce toxicity. Reduced barrier integrity was observed in tissues following exposure to each product, with reduced viability and increased cytotoxicity also shown. Similar changes in viability were also observed in A549 cells. Furthermore, whole cigarette smoke (CS) induced downstream phenotypic THP-1 changes and endothelial cell adhesion, an early marker of atherosclerosis. In contrast, exposure to next-generation delivery product (NGP) aerosol did not induce this response. Cytokine, histological and RNA analysis highlighted increased biomarkers linked to inflammatory pathways and immune cell differentiation following exposure to whole cigarette smoke, including GM-CSF, IL-1β, cleaved caspase-3 and cytochrome P450 enzymes. As a result of similar observations in human airway inflammation, we propose that our exposure platform could act as a representative model for studying such events in vitro. Furthermore, this model could be used to test the inflammatory or anti-inflammatory impact posed by inhaled compounds delivered to the lung.

Abstract
A 51-year-old female patient was presenting dyspnea for more than a year with no previous lung infections or surgery. Initially, a diagnostic computed tomography was made, showing a rare arterio-arterial malformation between the right inferior phrenic and right pulmonary artery leading into a vascular bundle in the middle lung lobe. Due to the patients' dyspnea and massive extent of malformation, the indication for transcatheter arterial embolization was made. The first transcatheter arterial embolization procedure involved the inferior phrenic and a selective branch of the internal thoracic artery. Interventional angiography as well as computed tomography revealed further extend of the malformation showing a connection of right lateral thoracic, hepatic, and inferior epigastric artery to the fistula. After one month, a second transcatheter arterial embolization of these arteries as well as a second approach of the proximal internal thoracic artery was performed. In the follow-up the patient described a substantial improvement of her dyspnea and showed no signs of infections. A phrenic artery to pulmonary artery fistula is an extremely rare case occurring congenital or acquired. Patients may be asymptomatic or present, among others, dyspnea, hemoptysis, pulmonary infections and congestive heart failure. Symptomatic patients require treatment using transcatheter arterial embolization or surgical resection. The patient had dyspnea and a substantial extent of malformation with possibly complicated clinical course. The recommended less invasive treatment using transcatheter arterial embolization was successfully performed. In conclusion, our patient represented a rare congenital case of systemic and pulmonary artery communication, which we were able to treat sufficiently with coil embolization.

Abstract
We sought to evaluate the impact of transitioning a multi-country HIV training program from in-person to online by comparing digital training approaches implemented during the pandemic with in-person approaches employed before COVID-19. We evaluated mean changes in pre-and post-course knowledge scores and self-reported confidence scores for learners who participated in (1) in-person workshops (between October 2019 and March 2020), (2) entirely asynchronous, Virtual Workshops [VW] (between May 2021 and January 2022), and (3) a blended Online Course [OC] (between May 2021 and January 2022) across 16 SSA countries. Learning objectives and evaluation tools were the same for all three groups. Across 16 SSA countries, 3023 participants enrolled in the in-person course, 2193 learners participated in the virtual workshop, and 527 in the online course. The proportions of women who participated in the VW and OC were greater than the proportion who participated in the in-person course (60.1% and 63.6%, p<0.001). Nursing and midwives constituted the largest learner group overall (1145 [37.9%] vs. 949 [43.3%] vs. 107 [20.5%]). Across all domains of HIV knowledge and self-perceived confidence, there was a mean increase between pre- and post-course assessments, regardless of how training was delivered. The greatest percent increase in knowledge scores was among those participating in the in-person course compared to VW or OC formats (13.6% increase vs. 6.0% and 7.6%, p<0.001). Gains in self-reported confidence were greater among learners who participated in the in-person course compared to VW or OC formats, regardless of training level (p<0.001) or professional cadre (p<0.001). In this multi-country capacity HIV training program, in-person, online synchronous, and blended synchronous/asynchronous strategies were effective means of training learners from diverse clinical settings. Online learning approaches facilitated participation from more women and more diverse cadres. However, gains in knowledge and clinical confidence were greater among those participating in in-person learning programs.

Abstract
AIMS Intrahepatic cholangiocarcinoma (iCCA) and hepatocellular carcinoma (HCC) differ in prognosis and treatment. We aimed to non-invasively differentiate iCCA and HCC by means of radiomics extracted from contrast-enhanced standard-of-care computed tomography (CT). MATERIALS AND METHODS In total, 94 patients (male, n = 68, mean age 63.3 ± 12.4 years) with histologically confirmed iCCA (n = 47) or HCC (n = 47) who underwent contrast-enhanced abdominal CT between August 2014 and November 2021 were retrospectively included. The enhancing tumour border was manually segmented in a clinically feasible way by defining three three-dimensional volumes of interest per tumour. Radiomics features were extracted. Intraclass correlation analysis and Pearson metrics were used to stratify robust and non-redundant features with further feature reduction by LASSO (least absolute shrinkage and selection operator). Independent training and testing datasets were used to build four different machine learning models. Performance metrics and feature importance values were computed to increase the models' interpretability. RESULTS The patient population was split into 65 patients for training (iCCA, n = 32) and 29 patients for testing (iCCA, n = 15). A final combined feature set of three radiomics features and the clinical features age and sex revealed a top test model performance of receiver operating characteristic (ROC) area under the curve (AUC) = 0.82 (95% confidence interval =0.66-0.98; train ROC AUC = 0.82) using a logistic regression classifier. The model was well calibrated, and the Youden J Index suggested an optimal cut-off of 0.501 to discriminate between iCCA and HCC with a sensitivity of 0.733 and a specificity of 0.857. CONCLUSIONS Radiomics-based imaging biomarkers can potentially help to non-invasively discriminate between iCCA and HCC.

Abstract
BACKGROUND Major depressive disorder (MDD) is a complex disorder with a significant public health burden. Depression remission is often associated with weight gain, a major risk factor for metabolic syndrome (MetS). The primary objective of our study was to assess prospectively the impact of response to antidepressant treatment on developing MetS in a sample of MDD patients with a current major depressive episode (MDE) and who are newly initiating their treatment. METHODS In the 6-month prospective METADAP cohort, non-overweight patients, body mass index <25 kg/m2, with MDD and a current MDE were assessed for treatment response after 3 months of treatment, and incidence of MetS after 3 and 6 months of treatment. Outcome variables were MetS, number of MetS criteria, and each MetS criterion (high waist circumference, high blood pressure, high triglyceridemia, low high-density lipoprotein-cholesterolemia, and high fasting plasma glucose). RESULTS In total, 98/169 patients (58%) responded to treatment after 3 months. A total of 2.7% (1/38) developed MetS out of which 12.7% (10/79) (p value < 0.001) had responded to treatment after 3 months. The fixed-effect regression models showed that those who responded to treatment after 3 months of follow-up had an 8.6 times higher odds of developing MetS (odds ratio = 8.58, 95% confidence interval 3.89-18.93, p value < 0.001). CONCLUSION Compared to non-responders, non-overweight patients who responded to treatment after 3 months of antidepressant treatment had a significantly higher risk of developing MetS during the 6 months of treatment. Psychiatrists and nurses should closely monitor the metabolic profile of their patients, especially those who respond to treatment.

Abstract
Cardiac arrest in the peri-operative period is rare but associated with significant morbidity and mortality. Current reporting systems do not capture many such events, so there is an incomplete understanding of incidence and outcomes. As peri-operative cardiac arrest is rare, many hospitals may only see a small number of cases over long periods, and anaesthetists may not be involved in such cases for years. Therefore, a large-scale prospective cohort is needed to gain a deep understanding of events leading up to cardiac arrest, management of the arrest itself and patient outcomes. Consequently, the Royal College of Anaesthetists chose peri-operative cardiac arrest as the 7th National Audit Project topic. The study was open to all UK hospitals offering anaesthetic services and had a three-part design. First, baseline surveys of all anaesthetic departments and anaesthetists in the UK, examining respondents' prior peri-operative cardiac arrest experience, resuscitation training and local departmental preparedness. Second, an activity survey to record anonymised details of all anaesthetic activity in each site over 4 days, enabling national estimates of annual anaesthetic activity, complexity and complication rates. Third, a case registry of all instances of peri-operative cardiac arrest in the UK, reported confidentially and anonymously, over 1 year starting 16 June 2021, followed by expert review using a structured process to minimise bias. The definition of peri-operative cardiac arrest was the delivery of five or more chest compressions and/or defibrillation in a patient having a procedure under the care of an anaesthetist. The peri-operative period began with the World Health Organization 'sign-in' checklist or first hands-on contact with the patient and ended either 24 h after the patient handover (e.g. to the recovery room or intensive care unit) or at discharge if this occured earlier than 24 h. These components described the epidemiology of peri-operative cardiac arrest in the UK and provide a basis for developing guidelines and interventional studies.

Abstract
Background The nature of the relationship between maternal tobacco smoking during pregnancy and the occurrence of children's behavioural problems is still a matter of controversy. We tested this association using data collected among a sample of children followed from pregnancy to early adolescence (age 11.5 years), accounting for multiple parents’, children's and family characteristics. Methods Data come from 1424 mother-child pairs participating in the EDEN mother-child cohort set up in France. Using repeated measures (3, 5.5, 8 and 11.5 years) of the mother-reported Strengths and Difficulties Questionnaire, we estimated trajectories of children's emotional and behavioural difficulties. Two aspects of maternal smoking were studied: the timing and the level of use (cigarettes/day) during the first trimester of pregnancy. Multinomial regression models controlled for confounding factors including maternal mental health and socioeconomic characteristics using propensity scores with the overlap weighting technique. Results Contrary to bivariate analyses, in propensity score-controlled regression models, maternal smoking throughout pregnancy was no longer significantly associated with offspring emotional or behavioural difficulties. Maternal heavy smoking (≥10cigarettes/day) remained significantly associated with intermediate levels of overall emotional and behavioural difficulties (OR 1.64, 95%CI 1.04-2.58) and conduct problems (OR 3.05 95%CI 1.22-7.61), as well as with high levels of conduct problems symptoms (OR 2.82 95%CI 0.88-9.06) - although the latter did not reach statistical significance. Conclusions The association between maternal smoking in pregnancy and offspring emotional and behavioural difficulties appears to be largely explained by women's other characteristics. However, maternal heavy smoking appears to be related to offspring behavioural difficulties beyond the role of confounding characteristics. Key messages • The association between maternal smoking in pregnancy and offspring emotional and behavioural difficulties seem largely explained by the family's socio-demographic and behavioural characteristics. • Maternal heavy smoking appears to be related to offspring behavioural difficulties beyond the role of confounding characteristics.

Abstract
Abstract
Background
Low-density lipoprotein (LDL-C) lowering is imperative in cardiovascular disease prevention. Effectively translating the evidence for LDL-C lowering to maximize clinical and public health benefits depends on the availability of accurate LDL-C results from clinical laboratories to guide therapy. Furthermore, prior work has raised the possibility that cholesterol esterase transfer protein (CETP) inhibition could interfere with accurate assessment of LDL-C.
Purpose
We aimed to compare accuracy of three clinically implemented LDL-C equations in a clinical trial of CETP inhibition.
Methods
Men and women aged 18–75 years with dyslipidaemia were recruited from 17 sites in the Netherlands and Denmark. Patients were randomly assigned to one of nine groups using various combinations of the CETP inhibitor TA-8995, statin therapy, and placebo. In pooled measurements over 12 weeks, we calculated LDL-C by the Friedewald, Martin/Hopkins, and Sampson equations, and compared values with preparative ultracentrifugation (PUC) LDL-C as the reference measure (also known as “beta quantification”). Based on prior literature and dyslipidaemia guidelines, we examined correct classifications across the LDL-C 1.81 mmol/L cutpoint in the subgroup of patients with triglycerides of 1.69–4.51 mmol/L.
Results
The analysis included 242 patients contributing 921 observations. The full distributions of differences between LDL-C estimates and PUC are shown in Figure 1. Overall median LDL-C differences between estimates and PUC were small: Friedewald, 0.00 (25th, 75th: −0.10, 0.08) mmol/L; Martin/Hopkins, 0.02 (−0.08, 0.10) mmol/L; and Sampson, 0.05 (−0.03, 0.15) mmol/L. In the subgroup with estimated LDL-C <1.81 mmol/L and triglycerides 1.69–4.51 mmol/L, the Friedewald equation underestimated LDL-C with a median difference versus PUC of −0.25 (−0.33, −0.10) mmol/L, whereas the Martin/Hopkins equation corrected this issue with a median difference of 0.00 (−0.08, 0.10) mmol/L and the Sampson equation showed tendency towards underestimation with a median difference of −0.06 (−0.13, 0.00) mmol/L. In patients with triglyceride levels of 1.69–4.51 mmol/L, Figure 2 shows the proportion of LDL-C levels classified by the equations as < or ≥1.81 mmol/L that were correctly classified when compared with PUC. All three equations showed >95% accuracy when estimated LDL-C levels were ≥1.81 mmol/L. However, the proportion of LDL-C observations <1.81 mmol/L that were correctly classified compared with PUC was 71.4% by Friedewald versus 100.0% by Martin/Hopkins and 93.1% by Sampson.
Conclusion
In Europeans with dyslipidaemia, our analysis shows improved accuracy in LDL-C when using contemporary LDL-C equations over the Friedewald equation, particularly when using the Martin/Hopkins equation. High levels of accuracy with the Martin/Hopkins equation were seen in individuals treated with CETP inhibition and even in the context of low LDL-C and high triglyceride levels.

Abstract
BackgroundPsoriatic arthritis (PsA) is a complex condition that requires high levels of self-management from those living with the condition. It is associated with many comorbidities, including depression, metabolic syndrome, and increased cardiovascular disease risk and can adversely affect quality of life. There is growing evidence that people living with psoriatic arthritis (PsA) are more likely to be overweight, consume alcohol above recommended levels, smoke, be affected by poor sleep, fatigue, anxiety, and take insufficient exercise for healthy living. These modifiable health behaviours further increase the already known risk of cardiovascular morbidity and mortality. These issues are not systematically addressed in routine clinical care due to low confidence in effective delivery and time constraints.ObjectivesTo co-develop evidence-based patient-focused learning materials to support healthy lifestyle changes for people living with PsA.MethodsThe development of the materials was overseen by a steering group of people living with PsA, psychologists, rheumatologists, and researchers. The COM-B model was used in the development of the materials, and they are designed around motivational interviewing principles. Firstly, a systematic literature review was performed to establish the evidence for the current burden and potential interventions aimed at these issues in PsA. These included diet, weight, alcohol, smoking, exercise, anxiety, depression, and stress. An initial focus group of people living with PsA was used to identify priority behaviours and ideas for content.The steering group developed draft materials, and we partnered with a design agency to create engaging materials. They developed a website and downloadable postcards. A second focus made up of people living with PsA was held for people to give their views on the draft content for the materials and initial design ideas. A third focus group was held with people living with PsA and a fourth with clinicians to refine the design materials and ensure they were accessible, interesting, and helpful to initiate and maintain change. A final evaluation survey was performed to review the draft website before launching the final materials. The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) approved the final materials.ResultsFollowing the steering and focus groups’ input, 15 candidate topics were prioritised (Table 1). A website and downloadable postcards summarising each of the topics were developed by the design team and refined following feedback from the patient focus groups. An example of the postcard for ‘keeping active’ can be found in Figure 1. The resources are free to use and can be accessed at https://www.informatree.org.Table 1.Topics1Pain2Fatigue3Healthcare appointments4Tobacco5Different treatments6Alcohol7Work8Social support9Food and weight10Sleep11Keeping active12Mood13Intimacy14Travel15Using treatmentsFigure 1.During the development of the website and downloadable postcards, particular attention was paid to making the material as accessible and as friendly as possible for patients.ConclusionThis project created patient-focused information to support behaviour change in clinical practice.

Abstract
Abstract
Introduction
In the UK, pharmacists with additional clinical skills now work in emergency departments (1). Known as Emergency Department Pharmacist Practitioners (EDPPs), the role was developed in response to a shortage of doctors and nurses. EDPPs carry out activities typical of traditional hospital pharmacists, but also novel ‘practitioner’ activities such as examining patients. They also may act as designated care providers with overall responsibility for patients, which includes a responsibility to safeguard patients (children and vulnerable adults) from harm – as is required of other healthcare professionals who take on that role. The initial safeguarding process comprises four stages: recognition, ensuring safety, documentation and escalation. Professional competence, i.e. to safeguard patients, is underpinned by knowledge of the subject, but also the ability to apply that knowledge (2).
Aim
To investigate what EDPPs know and understand about safeguarding vulnerable children and adults.
Methods
Past and current students of an ‘Advanced Specialist Training in Emergency Medicine’ programme, which delivers additional clinical skills to pharmacists, were interviewed to explore their knowledge and understanding of safeguarding. Interview questions were developed from review of relevant literature, as were four vignettes which were used to further explore participants’ understanding i.e. apply their knowledge of safeguarding to realistic scenarios. Vignettes concerned victims of: theft, sexual abuse, physical abuse and a medication error. A Social Worker reviewed the vignettes for plausibility, suggesting changes e.g. to victim characteristics. The interview schedule and vignettes were then piloted by two acute medicine pharmacists. For analysis, interview transcripts were reviewed with template analysis used to code data to four a priori themes (stages of the initial safeguarding process), and new themes that emerged throughout the process.
Results
Thirteen EDPPs were interviewed (four in 2016, and then a further nine in 2019 following delays due to competing research commitments). In addition to the four a priori themes, a further six themes were identified: scope of safeguarding; responsibility to safeguard; resources and setting; education, training and experiential learning; multidisciplinary working and communication; and culture. Overall, participants had a broad and often detailed knowledge of safeguarding. All four stages were frequently described which demonstrates EDPPs awareness of how safeguarding concerns are both recognised and responded to. Somewhat unsurprisingly, participants were generally more comfortable when responding to medicines related concerns although whether these should be reported via safeguarding or error systems is currently unclear. Several participants were more involved with the formal escalation of issues, and one participant had safeguarding issues escalated to them and had given evidence in court.
Conclusion
Although interview phases were three years apart, no thematic differences were identified between these phases and thematic saturation was also achieved. EDPPs interviewed were aware of the different types of maltreatment and the safeguarding process. Safeguarding training for pharmacists should include a focus on the importance of good inter-professional communication. Training should also include information about the types of medication error (e.g. type and severity) that require escalation via safeguarding, but these first need to be confirmed through future research.

Abstract
BACKGROUND Nitric oxide synthase (NOS) activity, an enzyme potentially involved in the major depressive episodes (MDE), could be indirectly measured by the L-Citrulline/L-Arginine ratio (L-Cit/L-Arg). The aim of this study was: (1) to compare the NOS activity of patients with a MDE to that of healthy controls (HC); (2) to assess its change after antidepressant treatment. METHODS A total of 460 patients with a current MDE in a context of major depressive disorder (MDD) were compared to 895 HC for NOS activity (L-Cit/L-Arg plasma ratio). L-Arg and L-Cit plasma levels were measured using a MS-based liquid chromatography method. Depressed patients were assessed at baseline, and after 3 and 6 months of antidepressant treatment for depression severity and clinical response. RESULTS Depressed patients had a lower NOS activity than HC at baseline [0.31 ± 0.09 v. 0.38 ± 0.12; 95% confidence interval (CI) -0.084 to -0.062, p < 0.0001]. Lower NOS activity at baseline predicted a higher response rate [odds ratio (OR) = 29.20; 95% CI 1.58-536.37; p = 0.023]. NOS activity in depressed patients increased significantly up to 0.34 ± 0.08 after antidepressant treatment (Est = 0.0034; 95% CI 0.0002-0.0067; p = 0.03). CONCLUSIONS Depressed patients have a decreased NOS activity that improves after antidepressant treatment and predicts drug response. NOS activity may be a promising biomarker for MDE in a context of MDD.

Abstract
BACKGROUND Many countries, including the United Kingdom, have established Emergency Department (ED) pharmacy services where some ED pharmacists now work as practitioners. They provide both traditional pharmaceutical care and novel practitioner care i.e. clinical examination, yet their impact on quality of care is unknown. AIM To develop a framework of structures, processes and potential outcome indicators to support evaluation of the quality of ED pharmacy services in future studies. METHOD Framework components (structures, processes and potential outcome indicators) were identified in three ways: from a narrative review of relevant international literature, and separate panel meetings with ED pharmacists and then other ED healthcare professionals. Structures and processes were collated into categories developed iteratively throughout data collection, with outcome indicators collated into six domains of quality as proposed by the Institute of Medicine. These raw data were then processed e.g. outcome indicators screened for clarity i.e. those which explicitly stated what would be measured were included in the framework. RESULTS A total of 190 structures, 533 processes, and 503 outcome indicators were identified. Through data processing a total of 153 outcome indicators were included in the final framework divided into the domains safe (32), effective (50), patient centred (18), timely (24), efficient (20) and equitable (9). CONCLUSION The first framework specific to the quality evaluation ED pharmacy services, service evaluators should validate potential outcome indicators prior to their use. The minimum expected of a high-quality service should also be defined to enable interpretation of relevant measurements.

Abstract
Aniridia is a condition characterized by defects or absence of the iris. Since the eyes are a central point of attention in the human face, these deformities are often covered with cosmetic implants. However, patients suffer from the static pupil diameter of these implants, resulting in high light sensitivity or inadequate night vision. Therefore, we present a functional iris implant based on dielectric elastomer actuators. These electric drives are characterized by a silent and continuous adaptation as well as a small construction volume and a low heat emission. Since they normally exhibit in-plane uniaxial motion, this displacement must be focused to operate similarly to the iris sphincter. Therefore, we investigated possible mechanical modifications of the setups to generate a directional motion. The results of the study are presented and discussed.Clinical Relevance- The proposed system design enables the functional treatment of aniridia and other accidental iris defects. In addition, the system serves as a basis for later developments of e.g. functional lenses that allow focus adjustment.

Abstract
Active urologic implants, such as bladder stimulators or artificial sphincters, are a widely-used approach for therapy of urinary incontinence. At present these devices are powered by primary batteries or conventional wireless power transferring techniques. As these methods are associated with several limitations, human body energy harvesting can be a promising alternative or complement for power supply. This paper introduces an approach to harvest energy from the urine flow inside the urethra with a mechatronic harvesting system based on a hubless flow turbine. Using a test bench approximating the flow conditions of the lower urinary tract, the feasibility of the harvesting principle is shown in-vitro.

Abstract
Abstract
Introduction/Objective
Bacillus cereus is a spore-forming, gram-positive rod, well known for causing food poisoning. In addition, this bacterium often presents as a contaminant of blood cultures. Differentiating true bacteremia from contamination of blood samples is important as it has treatment implications. Early recognition is necessary, as it can cause septic shock if untreated. We present a challenging case of food poisoning with concomitant bacteremia in a young patient with a history of diabetes mellitus (DM), celiac disease, and new-onset chronic kidney disease (CKD).
Methods/Case Report
A 23-year-old adult male with a history of DM, new-onset CKD, and celiac disease presented with nausea, intermittent vomiting, and lower abdominal pain for 2 weeks. On initial evaluation, he had normal blood pressure but tachypnea and tachycardia. Physical examination was significant for left lower quadrant and flank tenderness. The symptoms were persistent and progressed to point that he could not tolerate meals due to vomiting. Two weeks earlier, he presented with similar complaints along with dysuria and was treated for suspected urinary tract infection with Co-trimoxazole. This time, further workup revealed normal white blood cell count (11.8 k/µL) with 81% neutrophils, elevated creatinine (3.56 mg/dL), blood urea nitrogen (49 mg/dL), and procalcitonin (0.39 ng/mL), with abnormal urinalysis showing increased turbidity, pyuria, and nitrituria. He was started on ceftriaxone, fluids, antiemetics and was admitted to the hospital for further management. The urine culture had no bacterial growth. Two sets of peripheral blood cultures (different sites at different times) had gram-positive rods which eventually turned out to be B. cereus, identified by matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS). Levofloxacin was started, and he reported improvement in nausea and vomiting by the next day of admission and was discharged.
Results (if a Case Study enter NA)
NA
Conclusion
Differentiating true B. cereus bacteremia from blood sample contamination is important. Additionally, no symptoms are specific for B. cereus-associated food poisoning, and the presence of risk factors doesn’t always favor this entity over other entities, hence adding difficulty to the diagnosis. A high index of suspicion is needed, as early intervention can prevent the development of life-threatening complications.

Abstract
Abstract
Background
Cardiovascular disease (CVD) remains the leading cause of death globally, taking an estimated 18 million lives each year. Digital health interventions (DHI), such as wearables and smartphone applications, have shown promise in CVD detection, prevention, and management. However, there are scarce data regarding clinician perspectives on the utility of DHI and identification of key elements to support adoption in clinical practice.
Method
In this cross-sectional study, a web-based survey was administered to 107 clinicians directly involved in the care of cardiac inpatients across multiple academic health care systems in the United States, between January 2020 and March 2021. Participants (1) reported their perceptions of DHI impact on their ability to care for patients with CVD, (2) rated the importance of factors related to DHI adoption, and (3) shared perspectives on using DHI for secondary CVD prevention to support guideline-directed medical therapy in patients after acute myocardial infarction. Descriptive statistics were analyzed and summarized as frequencies with percentages.
Results
Among survey respondents, 41% were women; 22% specialized in cardiovascular medicine; and 31% were practicing attendings (Table). Overall, 92% (86/94) of respondents believed that DHI would be important in offering advantages in cardiovascular patient care (Figure). Increasing patient adherence was reported as the most important benefit of DHI adoption by 39% of clinicians, followed by improvement in the patient-clinician relationship (29%), enabling remote care (18%), and improving patient experience (14%). Clinicians under age 40 years old, cardiologists, and internists were the groups more likely to consider DHI important in remote patient care, disease monitoring, and tele-visits, as compared to clinicians over age 40 years old or in other clinical specialties.
Conclusion
Our results highlight clinician perspectives on the advantages of DHI and the potential for its adoption for secondary prevention of CVD.

Abstract
Background Long COVID (LC) is an increasingly recognized late complication of COVID-19 infection. Cardiovascular involvement has also been implicated, however, the type and extent of the underlying cardiovascular injury remains unknown. Purpose To evaluate the association between ongoing symptoms and findings with cardiovascular magnetic resonance (CMR) in consecutive patients recently recovered from COVID-19 illness. Methods Prospective observational cohort study of patients recently recovered from COVID-19 illness and no previously known cardiovascular disease were included between April 2020 and April 2021. Demographic characteristics, cardiac blood markers, and CMR imaging a minimum of 4 weeks from the diagnosis were obtained. Results Of the 389 included patients, 192 (49%) were male, the mean (±standard deviation) age was 44 (±13) years and 61 (16%) required hospitalization during the acute illness. The median (IQR) time interval between COVID-19 diagnosis and CMR was 94 (71–165) days. 298 (77%) of patients continued to experience ongoing cardiovascular symptoms (long COVID, LC), including dyspnea, palpitations, atypical chest pain and fatigue at the time of CMR at least 4 weeks after the infection. In most patients, the symptoms were only effort related 137 (46%), whereas in 98 (33%) the symptoms affected the activities of daily life; 10 (3%) had severe and debilitating symptoms at rest. Compared to those with no LC (NLC, n=91), LC patients were more commonly hospitalized, had significantly higher native T1, native T2, and showed pericardial enhancement and effusion (Figure 1). There were no differences in cardiac biomarkers, left ventricular (LV) and right ventricular ejection fraction and mass. Proportionally, men and women were similarly affected (n=144 (73%) vs. n=157 (80%), p=0.18). Previous hospitalization was associated with hypertension and ongoing detectable troponin. LC status was associated with previous hospitalization and CMR findings of raised native T1 and native T2, and in females also pericardial enhancement. Severity of symptoms were associated with increased native T1 and T2 and decreased end-diastolic volume, whereas cardiac function showed no significant difference. Conclusions In this cohort of patients recently recovered from COVID-19 infection, ongoing cardiovascular symptoms were common. The LC status was related to previous hospitalization and CMR imaging findings of myopericardial inflammation. The extent and type of cardiovascular findings was associated with the severity of symptoms. These findings indicate the need for ongoing investigation of the long-term cardiovascular consequences of COVID-19. Funding Acknowledgement Type of funding sources: Foundation.

Abstract
Abstract
Objective
To develop a clinical risk score for individualized risk stratification of patients with clinically suspected myocardial inflammation.
Background
Myocardial inflammation is a prominent cause of non-ischaemic dilated cardiomyopathy, heart failure (HF) and sudden cardiac death.
Methods
This is a prospective multicentre longitudinal study of consecutive patients referred to cardiac magnetic resonance (CMR) with clinically suspected myocardial inflammation between October 2011 and December 2019 as a part of standard diagnostic pathway. Patients were followed up from the date of CMR. The outcome endpoints included major adverse cardiovascular event (MACE, cardiovascular mortality, sudden cardiac death, appropriate device discharge); or death or hospitalisation due to HF). A prognostic model was developed using Cox proportional hazards analysis and validated internally and externally.
Results
The final dataset included 722 subjects (50 years (40–61); males 422 (58%)). During a follow-up period of median 19 (15–23) months, there were 64 (9%) MACE and 130 (18%) HF events. Ten predictor variables qualified for entry into the prognostic model: age, sex, hematocrit, C-reactive protein, high-sensitive troponin-T (TNT), left and right ventricular ejection fraction, native T1 and T2, and late gadolinium enhancement (LGE). The final multivariable Cox regression model included native T2 (Figure 1A), TNT and LGE (Figure 1B) for the primary (Chi-square: 102.0, p<0.001) and secondary endpoint (Chi-square: 166.9, p<0.001), respectively. Cross-validation as well as external validation of the secondary models revealed good performance and no healthcare system effect. Based on the MyoRISK Score, patients were classified into three risk groups with respective event rates for MACE of 0%, 6.3% and 25.1%, and HF endpoint of 1.8%, 17.3% and 44.2%. TNT≥7 pg/ml allowed to efficiently preselect patients prior to CMR.
Conclusions
This is the first systematic assessment of outcomes in patients with clinically suspected myocardial inflammation, providing a non-invasive estimation of the probability of adverse events based on a score using readily available clinical parameters.

Abstract
Abstract
Aim
Electrolyte abnormalities are a common and serious consequence of nutritional deficiencies when patients are nil-by-mouth. Timely intervention with a multidisciplinary approach is known to improve outcome. This audit aimed to assess adequacy of initial electrolyte management and timing of dietetics referral in acute surgical patients requiring total parenteral nutrition in a university hospital.
Method
A retrospective audit of all general surgery patients referred to dietetics for total parenteral nutrition between January-December 2019 was performed. The following audit standards (from the time following admission) were applied: monitoring of electrolytes every 48-hours, treatment of electrolyte abnormalities within 24-hours of discovery; and referral to the dietetics service within 48-hours of nil-by-mouth being commenced.
Results
Data from 52 patients (27 females, median age 66) were analysed. Fifty-one (98%) had electrolytes measured every 48-hours, however magnesium, phosphate and/or calcium were not measured prior to dietetics input in 9 (17%). Forty electrolyte abnormalities requiring treatment were found in 28 patients (54%), though only 18 (64%) commenced treatment within 24-hours. The most common electrolyte abnormalities not corrected within 24-hours were phosphate and calcium (50%). 46% of patients were referred to dietetics after 48-hours of nil-by-mouth status.
Conclusions
In our unit, we found that basic electrolytes were frequently monitored in patients placed nil-by-mouth, however calcium, phosphate and magnesium were often omitted prior to dietetics input, and correction of abnormalities was sometimes delayed. Introduction of a local protocol-based approach for electrolyte monitoring with streamlined dietetics referrals is likely to improve adherence to best practice.

Abstract
Abstract
Aim
This case report showcases an unusual presentation of tophaceous gout, in an immunocompromised patient. Furthermore, through a literature review, we highlight challenges posed by immunocompromised patients, the clinical manifestations of gout in the hand and principles of management.
Method
We report the case of a 62-year-old lady with previous liver transplant on immunosuppressants. She was admitted with a left palmar abscess, pyogenic tenosynovitis of the index finger and was taken to theatre for debridement and washout. Superimposed infection was apparent. This originated from an exophytic mass extending from the palm to FDS tendon insertion. This was debulked and histologically confirmed as gout. A review of the literature was performed using key search terms on PubMed relating to manifestations of gout in the tendons of the hand, and in patients on immunosuppression.
Results
Reports in the literature describe cases of gouty tendinopathy in both flexor and extensor tendons. Reported symptoms include triggering, tendon rupture and tenosynovitis. Gout occurs in a higher frequency in transplant patients. This can be attributed to medications such as cyclosporine which predispose to hyperuricaemia. Management of this condition involves medical optimisation. Despite concurrent problems with wound healing in the immunocompromised with gout, surgical intervention may be required. Indications include superimposed infection, attenuated tendon glide, joint movement, and neuropathy. Perioperative antibiotics are recommended in all immunocompromised patients.
Conclusions
This case highlights an unusual presentation of gout and the challenges of managing patients on immunosuppressant therapy. A greater awareness of this condition will allow for appropriate management in this high-risk patient cohort.

Abstract
Abstract
Introduction
Medical tourism is expanding on a global basis, with patients seeking cosmetic surgery in countries abroad. Little information is known regarding the risks and outcomes of cosmetic tourism, in particular, for aesthetic breast surgery.
Method
A systematic-review was conducted using the PRISMA (Preferred Reporting Items for Systematic-reviews and Meta-analyses) guidelines. Fifty-seven titles were screened, 42 abstracts were reviewed leaving 30 full texts. Twenty-one of these met the inclusion criteria.
Results
One-hundred and fifty patients partook in cosmetic tourism for aesthetic breast surgery. Forty-two percent of patients had an implant-based procedure. Other procedures included mastopexy (n = 4), bilateral breast reduction (n = 10) and silicone injections (n = 2). One-hundred and sixty complications were recorded, common complications included wound infection 31% (n = 46), breast abscess/ collection 14% (n = 21), wound dehiscence 12% (n = 18) and ruptured implant 9% (n = 13). Clavien-Dindo classification of complications includes 67 (45%) IIIb-complications with 78 returns-to-theatre, 2 class-IV complications (ICU stay) and one class-V-death of a patient. Explanation occurred in 38% (n = 24) of implant-based augmentation patients.
Conclusions
Aesthetic breast surgery tourism is popular within the cosmetic tourism industry. However, with infective complications (31%) and return-to-theatre rates (45%) significantly higher than expected, it is clear that having these procedures abroad significantly increases the risks involved. Professional bodies for cosmetic surgery in each country must highlight and educate patients how to lower this risk if they do choose to have cosmetic surgery abroad. In this current era of an intra-pandemic world where healthcare is already stretched, the burden from cosmetic tourism complications must be minimised.

Abstract
Abstract
Introduction
The incidence of cutaneous malignant melanoma is increasing. Internationally, there is evidence of an association between melanoma incidence and higher socioeconomic status (SES). This study aims to assess the characteristics of patients with melanoma in NI, and correlate to SES.
Method
Retrospective review of electronic records for patients undergoing surgery for melanoma at the Northern Ireland Plastic Surgery Unit from August 2015 to March 2020. Patients were identified from theatre records and a prospectively collected sentinel lymph node database. The NI Multiple Deprivation Measure 2017 was used to measure SES.
Results
440 patients were included (F = 54%, M = 46%). Mean age=63 (M = 67, F = 59). Mean Breslow Depth (BD) = 2.61mm (Range 0.17 – 27mm). Females had significantly thinner tumours at presentation (mean BD 2.16mm. vs 3.1mm in males, p = 0.001). In males the commonest sites were head and neck (36%) and back (23%). In females, the commonest sites were lower limb (42%) and upper limb (23%). There was a positive correlation between higher SES and increased incidence of melanoma (correlation coefficient (CC) 0.922), but this did not correlate with an increase in Breslow depth (CC -0.020).
Conclusions
This study provides important information on melanoma in NI, including gender and site variances. Females were more commonly affected and were a mean of 8 years younger than males at diagnosis but presented with significantly thinner tumours. Unlike the rest of the UK, the commonest site in males was the head and neck. Higher SES was related to higher incidence of melanoma but with presentation at an earlier stage of disease.

Abstract
Introduction The COVID-19 pandemic, with associated pressures on healthcare services and workforce, had implications for final year Diagnostic Radiography students completing their training and transitioning into employment. The aim of this study was to explore their experience as novice practitioners starting work and integrating into the workforce during a time of national crisis. Methods Five early career Diagnostic Radiographers, eligible to join the temporary HCPC register, were recruited. One to one interviews were completed online exploring their thoughts, feelings and experiences. Participants had the option of using photographs to aid communication. Results Interviews were transcribed, emerging themes identified and coded. Four main themes emerged specifically related to the COVID-19 pandemic, (i) perceived challenges associated with joining the workforce, (ii) managing expectations and unexpected outcomes during transition, (iii) adapting to changes in systems and structures, (iv) sense of uncertainty relating to professional identity. The impacts were experienced beyond the work environment into social and personal lives. Participants demonstrated resilience as they adapted to their shifting lives and drew on the support of clinical colleagues and University academics for help. They did report feelings of concern and anxiety. The participants all expressed a sense of feeling valued and supported in their new roles. Conclusion The Pandemic was unprecedented and created uncertainty in terms of workforce requirements. This study highlights the personal impact and professional responses of novice practitioners, who felt a sense of duty and care to help support the NHS and others. Implications for practice This will help in the understanding of the transition of student into employment and what wider support needs to be in place prior, during and after this phase.

Abstract
Abstract
Introduction
Complete transection of the sciatic nerve following a closed femoral fracture is exceedingly uncommon. Delayed diagnosis may result due to this unrecognised injury pattern.
Case Description:
An 18-year-old male motorcyclist was referred following a significantly displaced closed, femoral fracture. The patient was sedated at the scene and transferred to theatre for definitive fixation, where an open reduction was performed via an anterior approach. Symptoms of paresthesia and weakness were reported immediately postoperatively, and formal neurological examination prompted an emergency MRI. On this basis, the patient was transferred to plastics and underwent surgical exploration, where complete transection of the sciatic nerve was identified just proximal to the bifurcation into the common peroneal and tibial nerve. A nerve gap of five centimetres was identified requiring reconstruction with grouped fascicular sural nerve grafts.
Discussion:
Complete transection of the sciatic nerve is a devastating injury that compromises the function of the posterior compartment of the thigh and all motor function below the knee. To our knowledge, reports of complete sciatic nerve transection secondary to a closed fracture of the femoral shaft are extremely rare in the pertinent literature, with only two other cases reported to date.

Abstract
BACKGROUND Hidradenitis suppurativa (HS) is a chronic, debilitating disease with a profound impact on the quality of life of patients. OBJECTIVES To describe a rare case of HS with postmenopausal onset, to review the literature data regarding late onset HS and to discuss the current knowledge on the role of endocrine abnormalities in the development of HS. CASE REPORT We report the case of a 68-year-old patient in whom HS occurred 10 years after menopause. She was referred to our clinic for the presence of an open fistula on the left groin, fibrotic scars and visible alteration of the vulvar anatomy due to numerous surgical interventions. The patient shared features of the metabolic syndrome (obesity, arterial hypertension, dyslipidemia, aortic atherosclerosis), but showed no signs of virilism and no hormonal abnormality. HS was controlled using antiseptics, topical retinoids and antibiotics. CONCLUSIONS This case is of particular interest given the late onset of HS, long time after menopause. The development of HS requires a complex interaction between genetic predisposing factors, endocrine dysregulation, metabolic alterations, bacterial overgrowth and an aberrant inflammatory response. Evidence points to an important role of sex-hormones in the emergence and progression of the disease, but the underlying mechanisms are still unclear. A better understanding of HS pathogenesis is needed to elucidate the precise way in which endocrine factors influence the disease onset and course. This would guide the way to novel therapies and a better control of this challenging disease.

Abstract
Introduction Borderline Personality Disorder is defined from its impulsivity issues regarding relationships, abandonment and rejection issues and emotional regulation problems. This personality disorder issue are hard to treat and often related to poor treatment outcomes. Nonetheless, Dialectical Behavioral Therapy stands as a great therapeutical approach that can be adapted. Objectives We tested a 6-month CBT protocol (ECCCLORE)-3 modules respectively working on emotion regulation, distress tolerance and relationships- in a French context to compare its effectiveness to treatment as Usual (TAU). Methods We recruited 56 patients suffering from BPD, 34 receiving ECCCLORE treatment and 22 receiving TAU. We assessed BPD traits, impulsivity with UPPS, aggressiveness with AQ12, Suicidal risk with SBQr and Hopelessness with H. Results Our results revealed the effectiveness of this 6 months DBT adaptation for decreasing BPD traits and most of clinical dimensions. The dynamic analysis revealed the mediating effect of AQ12. Conclusions Shortened treatment protocol are effective for reducing symptoms. Further research is needed to replicate these results.

Abstract
In this paper, we present an experimental and theoretical study of the photo-dissociation of free-flying dimer radical cations of pyrene (C16H10)2+. Experimentally, the dimers were produced in the plasma of an electron cyclotron resonance ion source and stored in an electrostatic ion storage ring, the Mini-Ring for times up to 10 ms and the photo-dissociation spectrum was recorded in the 400 to 2000 nm range. Two broad absorption bands were observed at 550 (2.25 eV) and 1560 nm (0.79 eV), respectively. Theoretical simulations of the absorption spectrum as a function of the temperature were performed using the Density Functional based Tight Binding approach within the Extended Configuration Interaction scheme (DFTB-EXCI) to determine the electronic structure. The simulation involved all excited electronic states correlated asymptotically with the five lowest excited states D1-D5 of the monomer cation and a Monte Carlo exploration of the electronic ground state potential energy surface. The simulations exhibit three major bands at 1.0, 2.1 and 2.8 eV respectively. They allow assigning the experimental band at 1560 nm to absorption by the charge resonance (CR) excited state correlated with the ground state of the monomer D0. The band at 550 nm is tentatively attributed to dimer states correlated with excited states D2-D4, in the monomer cation. Simulations also show that the CR band broadens and shifts towards longer wavelength with increasing temperature. It results from the dependence on the geometry of the energy gap between the ground state and the lowest excited state. The comparison of the experimental spectrum with theoretical spectra at various temperatures allows us to estimate the temperature of the stored (C16H10)2+ in the 300-400 K range, which is also in line with the expected temperatures of the ions deduced from the analysis of the natural decay curve.

Abstract
This paper presents the Mechanical Ventilator Milano (MVM), a novel intensive therapy mechanical ventilator designed for rapid, large-scale, low-cost production for the COVID-19 pandemic. Free of moving mechanical parts and requiring only a source of compressed oxygen and medical air to operate, the MVM is designed to support the long-term invasive ventilation often required for COVID-19 patients and operates in pressure-regulated ventilation modes, which minimize the risk of furthering lung trauma. The MVM was extensively tested against ISO standards in the laboratory using a breathing simulator, with good agreement between input and measured breathing parameters and performing correctly in response to fault conditions and stability tests. The MVM has obtained Emergency Use Authorization by U.S. Food and Drug Administration (FDA) for use in healthcare settings during the COVID-19 pandemic and Health Canada Medical Device Authorization for Importation or Sale, under Interim Order for Use in Relation to COVID-19. Following these certifications, mass production is ongoing and distribution is under way in several countries. The MVM was designed, tested, prepared for certification, and mass produced in the space of a few months by a unique collaboration of respiratory healthcare professionals and experimental physicists, working with industrial partners, and is an excellent ventilator candidate for this pandemic anywhere in the world.

Abstract
BACKGROUND Syndactyly is a common congenital condition that can present sporadically or in relation to an underlying genetic condition. Little contemporary published data exists detailing specific rates of presentation and surgical intervention, especially in Western European population. This is the first published review of operative intervention rates for the condition over time in Northern Ireland. METHODS A ten-year retrospective review of electronic operative records from January 2007 - October 2017 was carried out within Northern Ireland's regional tertiary centre Royal Belfast Hospital for Sick Children (RBHSC). All congenital hand surgery in the country was performed here during the period reviewed, by a single surgeon. Patient age at surgical intervention, their sex, digits involved and clinical grade of syndactyly was recorded. RESULTS One hundred and twenty four cases were returned following the review. On individual analysis 22 cases were excluded as they were not primary congenital syndactyly. The remaining 102 cases were all Caucasian. Six cases were toe syndactyly while 96 cases involved the upper limb digits. The group consisted of 70 males and 32 female infants. Age range at time of surgical intervention was 8 months to 14 years with a median age of 26 months. For clinical grade of upper limb syndactyly; 35 cases in the data set were classed as simple incomplete, 34 cases as simple complete, 17 as complex and 5 cases as complicated syndactyly. The remaining 5 cases lacked clear documentation. The most common site of syndactyly was between the ring and middle finger (40/102). Annual frequency of operative intervention has trended upwards in the period studied. CONCLUSION This case review adds epidemiological data on the operative incidence of syndactyly cases in Northern Ireland - a relatively isolated genetic population. Overall rates of incidence have increased over the past 10 years. It remains unclear if this is due to new environmental influences on the developing population or increased referral for surgical intervention over time.Levels of evidence - IV (Case Series).

Abstract
BACKGROUND With funding from the United States Health Resources Service Administration (HRSA), a consortium of health professional training institutions from Africa developed HIV-specific, interprofessional, team-based educational resources to better support trainees during the transition period between pre-service training and professional practice. METHODS Ten faculty members representing nine medical and nursing schools in sub-Saharan Africa (SSA) developed a training package of modules focused on core clinical, public health, interprofessional education (IPE), and quality improvement (QI) domains related to HIV service delivery. Curriculum development was informed by a rapid needs assessment of existing tools and future needs for HIV education across 27 SSA health professions training institutions. A total of 17 modules were developed, targeted at newly qualified health care professionals to be taught in a series of two-day workshops meant to complement existing institution specific HIV-curricula. RESULTS Between April and July 2019, a comprehensive case-based HIV training package was developed to support trainees in transition from pre-service training to independent professional practice. Each module, addressing different elements of interprofessional practice, was intended to be delivered in an interprofessional format. Thus far, 70 health professions training institutions in 14 countries have implemented the program; 547 educators facilitated STRIPE workshops, with a total of 5027 learners trained between September 2019 and September 2020. CONCLUSIONS To our knowledge this is the first IPE HIV-specific curriculum explicitly focused on enhancing the quality of training provided to graduating health care professionals working in SSA. The collaborative, cross-institutional, interprofessional approach to curriculum development provides a benchmark for how best-practice approaches to education can be disseminated in SSA.
