Abstract
Interprofessional education (IPE) has been used for instilling a positive safety culture within healthcare, yet what interventions work to change healthcare student attitudes and how improved patient safety outcomes are best achieved with this intervention, is unclear and challenging to evaluate. A realist synthesis was undertaken to ascertain how, why, and in what circumstances IPE activities result in a positive change to student attitudes to patient safety. Database searches of CINAHL, MEDLINE, Scopus, and Eric were undertaken in April 2022 to identify relevant studies. Synthesis with a realist framework of analysis, coupled with the development of a program theory was conducted to identify interactions among contexts, intervention, mechanisms, and outcomes (CIMO). Twenty-three articles eligible for inclusion articulated environments in which varied contexts, interventions, and mechanisms were activated to influence student attitudes to patient safety. Findings from this realist synthesis informs awareness into the methods of delivering and evaluating IPE activities and offers new perspectives for educators in planning and evaluating future IPE from a collaborative and positive safety culture perspective.

Abstract
Lung transplantation is currently the gold standard treatment for end-stage lung diseases. Advances in the preservation of donor lungs, the surgical technique and immunosuppressive therapy have led to lung transplantation now being a routine procedure. Nevertheless, the shortage of donor organs, the acute and particularly chronic lung allograft dysfunction (CLAD) still represent major challenges even in experienced centers. Research in this area is still necessary to improve the long-term survival of lung recipients.

Abstract
PURPOSE The Carer Assessment of medicaTion management guidanCe for people with dementia at Hospital discharge (CATCH) tool was developed to examine the carer's experiences of medication management guidance delivery at discharge. This study explored its factor structure, characterized carers' experiences at discharge, and identified predictors of carer preparedness to manage medications at discharge. METHODS A cross-sectional survey of carers across Australia was distributed. Survey responses were analyzed descriptively, and exploratory factor and regression analyses were performed. RESULTS A total of 185 survey responses were completed. Exploratory factor analysis revealed 2 factors in the CATCH tool: (1) shared and supported decision-making in medication management (16 items loading 0.47 to 0.93); 2) provision of medication management guidance that is easy to understand (4 items loading (0.48 to 0.82). Internal consistency was acceptable (Cronbach alpha >0.8). Almost 18% of participants stated that they were not included in decisions about medications for people with dementia. The carer reported that the measure of how guidance is provided was positively related to their confidence in the management of medications postdischarge and satisfaction ( P < 0.05 for both). CONCLUSIONS The CATCH tool can give the patient and carer an opportunity to provide feedback on key elements of medication management guidance delivered at discharge.

Abstract
BACKGROUND Pain can have a serious impact on a patient's physical, mental, and social health, often causing their quality of life to decline. Various nicotine dosage forms, such as nicotine patches and nasal spray, have been developed and used as analgesics in clinical settings. However, there is controversy over the anti-nociceptive effects of nicotine among different clinical trials. The purpose of this meta-analysis is to quantify the analgesic effect of nicotine patches, nicotine nasal spray, and tobacco smoking on pain in humans. METHODS Relevant articles published in English prior to July 2023 were identified using the PubMed, Cochrane Library, and Embase online databases in accordance with PRISMA (2020) guidelines. Two reviewers independently screened and selected studies, extracted data, and assessed the quality of the included studies using version 2 of the Cochrane risk-of-bias tool for randomized trials (RoB 2). RStudio was used for data synthesis, heterogeneity assessment, sensitivity analysis, publication bias assessment, trim-and-fill analyses, and generating forest plots. RESULTS Sixteen eligible articles, including k = 5 studies of pain tolerance (n = 210), k = 5 studies of pain threshold (n = 210), and k = 12 studies of pain scores (N = 1249), were included for meta-analysis. Meta-analytic integration for pain threshold (Hedges' g = 0.28, 95% CI = 0-0.55, Z = 1.99, p = 0.05) and pain tolerance (Hedges' g = 0.32, 95% CI = 0.05-0.59, Z = 2.30, p = 0.02) revealed that nicotine administered via tobacco smoke generated acute analgesic effects to thermal stimuli. Meta-analytic integration for pain scores revealed that nicotine had a weak anti-nociceptive effect on postoperative pain of -0.37 (95% CI = -0.77 to 0.03, Z = -1.80) but with no statistical significance (p = 0.07). In addition, a limited number of included studies revealed that long-term smoking produced hyperalgesia that may be characterized as small to medium in magnitude (Hedges' g = 0.37, 95% CI = 0.29-0.64, Z = 5.33, p < 0.01). CONCLUSION These results help to clarify the mixed outcomes of trials and may ultimately inform the treatment of pain. We observed that acute nicotine administration prolonged the laboratory-induced pain threshold and tolerance time and may mildly relieve postoperative pain. In addition, long-term tobacco smoking may have a nociceptive effect on different types of chronic pain. More research is needed to determine the anti-nociceptive effects of nicotine in humans, and to understand the optimal timing, dose, and method of delivery of nicotine.

Abstract
INTRODUCTION The COVID-19 pandemic has caused oncological services worldwide to face unprecedented challenges resulting in treatment disruption for surgical patients. Hepatopancreatico-biliary (HPB) cancers are characterised by rapid disease progression. This study aims to assess delays in receiving surgery for this patient cohort during the first COVID-19 wave. METHODS Patients undergoing surgery between April and July 2020 (COVID-19 period) were compared with a control group from the preceding year. Delay in receiving surgery was defined as more than 50 days between referral and surgery date. Statistical analysis was carried out to evaluate predictors of delay and short-term outcomes. RESULTS During the COVID-19 and pre-COVID-19 periods, 94 and 115 patients underwent surgery, respectively. No patients contracted COVID-19 postoperatively. Some 118 patients waited more than 50 days for surgery versus 91 who received surgery within 50 days from referral. Independent predictors for surgical delay were undergoing surgery in the COVID-19 era (odds ratio (OR) 2.2, 95% confidence interval (CI) 1.2-4.1; p=0.015), referral pathway (OR 35.1, 95% CI 4.2-296; p=0.001) and presenting pathology (OR 8.3, 95% CI 1.2-56.1; p=0.03). Short-term outcomes were comparable between groups. CONCLUSIONS Patient referral pathway and presenting pathology may contribute to delays in undergoing HPB cancer surgery during COVID-19 outbreaks. It is hoped that a better understanding of these factors will aid in designing shifts in healthcare policy during future pandemic outbreaks.

Abstract
AIMS Minor hepatectomy, which is increasingly carried out laparoscopically (LLR), is a cornerstone of curative treatment for hepatocellular carcinoma (HCC). The majority of relevant publications however originate from regions with endemic viral hepatitis. Although the incidence of HCC in the UK is increasing, little is known about outcomes following LLR. METHODS Consecutive patients undergoing minor (involving ≤2 segments) LLR or open resection (OLR) at our institute between 2014 and 2021 were compared. Selection from a plethora of factors potentially impacting on overall (OS) and disease free survival (DFS) was optimised with Lasso regression. To enable analysis of patients having repeat resection, multivariate frailty modelling was utilised to calculate hazard ratios (HR). RESULTS The analysis of 111 liver resections included 55 LLR and 56 OLR. LLR was associated with a shorter hospital stay (5 ± 2 vs. 7 ± 2 days; p < 0.001) and a lower comprehensive complication index (4.43 vs. 9.96; p = 0.006). Mean OS (52.3 ± 2.3 vs. 49.9 ± 3.0 months) and DFS (33.9 ± 3.4 vs. 36.5 ± 3.6 months; p = 0.59) were comparable between LLR and OLR, respectively (median not reached). Presence of mixed cholangiocarcinoma/HCC, satellite lesions and AFP level predicted OS and DFS. In addition tumour size was predictive of DFS. CONCLUSIONS In the studied population minor LLR was associated with shorter hospital stay and fewer complications while offering non-inferior long-term outcomes. A number of predictors for disease free survival have been elucidated that may aid in identifying patients with a high risk of disease recurrence and need for further treatment.

Abstract
OBJECTIVES Although there is growing evidence that in utero exposure to power plants increases the risk of adverse birth outcomes, studies have focused on coal-fired plants and single US locations, limiting generalizability. We used birth certificate data from 50 states and DC to examine the associations between prenatal exposure to power plants and birth outcomes overall and by race/ethnicity. METHODS We linked 2009-2018 county-level microdata natality files on 34,674,911 singleton births from 50 states and DC with 9-month county-level averages of power plant fuel consumption based on month/year of birth. We estimated linear regression models for birth weight and gestational age and probit models for the dichotomous outcomes of low birth weight, small for gestational age (SGA), and preterm birth. We subsequently examined interactions between plant fuel consumption and race/ethnicity. RESULTS Overall, 69.1% of counties had any power plant fuel consumption. Although we found no overall effects of prenatal exposure to power plants on birth weight or SGA, a significant interaction (both P < 0.01) revealed that a 10% increase in fuel consumption was associated with infants born to White women having slightly lower birth weights (1.76 g; 95% confidence interval = -2.87, -0.65) and higher risk of being born SGA (0.0002; 95% confidence interval = 0.0002, 0.0002). CONCLUSION Power plants have negative effects on infant health, which exist independent of locality.

Abstract
National Institute for Occupational Safety and Health (NIOSH) researchers continue to study worker exposure to respirable crystalline silica (RCS) and develop interventions to reduce these exposures. Occupational overexposures to RCS continue to cause illness and deaths in many industries and RCS has been identified as a serious exposure risk associated with hydraulic- fracturing operations during oil and gas extraction. In 2016 the Occupational Safety and Health Administration (OSHA) reduced the permissible exposure limit (PEL) to 0.05 milligrams of silica per cubic meter of air, averaged over an 8-hour day. This mandate requires hydraulic-fracturing operations to implement dust controls and safer work methods to protect workers from silica exposures above this PEL by June 23, 2021. At hydraulic-fracturing sites utilizing sand movers, pneumatic transfer of fracking sand is the primary source of aerosolized RCS. Currently, there are limited commercially available engineering controls for the collection of dust emitted from thief hatches on sand movers. The goal of this research is to develop a robust, cost-effective, weather resistant, portable, self-cleaning dust collection system that can be retrofitted onto sand mover thief hatches. A prototype was designed, built, and tested, and it was determined that the system could handle flows in the range of 600 to 1300 cfm with loading/cleaning cycle times of 40 and 5 minutes respectively and demonstrated operating efficiencies of 97-99%. Further development of this NIOSH prototype is being done in collaboration with an industry partner with the goal of developing a commercially viable, cost-effective solution to reduce RCS at hydraulic-fracturing sites around the world.Implications: This research has verified that airborne dust created by pneumatic transfer of fracking sand can be effectively collected using a passive cartridge filter system, and that the filters can be cleaned using blasts of air. Mounting these units to the thief hatches of sand movers will significantly reduce dust emissions from sand movers on hydraulic fracturing sites. Thus, this system offers the Oil and Gas Industry a method to reduce worker exposure to RCS on hydraulic fracturing sites that utilize sand movers. The success of this prototype has led researchers to devise a modified version for collecting dust at conveyor transfer points.

Abstract
BACKGROUND Students from a range of health disciplines need to learn from people with lived experience of mental distress and recovery to develop recovery capabilities for mental health practice. AIMS The aims of this study are to describe the co-design of a teaching resource, to explore the experience of people with lived experience during the resource development, and to evaluate the outcome of the resource on student recovery capabilities. METHOD Using a sequential mixed method, a project group consisting of six people with lived experience and 10 academics from five health disciplines was convened to co-develop teaching resources. People with lived experience met independently without researchers on several occasions to decide on the key topics and met with the research team monthly. The teaching resource was used in mental health subjects for two health professional programmes, and the Capabilities for Recovery-Oriented Practice Questionnaire (CROP-Q) was used before and after to measure any change in student recovery capabilities. Scores were compared using the Wilcoxon signed rank test. The people with lived experience were also interviewed about their experience of being involved in constructing the teaching resources. Interviews were audiotaped, transcribed, and analysed thematically. RESULTS The finished resource consisted of 28 short videos and suggested teaching plans. Occupational therapy and nursing student scores on the CROP-Q prior to using the educational resource (n = 33) were 68 (median) and post scores (n = 28) were 74 (median), indicating a statistically significant improvement in recovery capability (P = 0.04). Lived experience interview themes were (i) the importance of lived experience in education; (ii) personal benefits of participating; (iii) co-design experience; and (iv) creating the resource. CONCLUSION Co-design of teaching resources with people with lived experience was pivotal to the success and quality of the final product, and people with lived experience described personal benefits of participating in resource development. More evidence to demonstrate the use of the CROP-Q in teaching and practice is needed.

Abstract
PURPOSE We sought to design a micro-curriculum to structure supervised clinical placements for junior medical students within a variety of community-based settings of differing clinical disciplines. Given the gaps in the literature, this paper reflects on the opportunities and challenges of our design, implementation, and evaluation strategies in constructing an integrated task-based micro-curriculum for interprofessional community-based learning in year 2 of a four-year graduate entry program. METHODS The design was informed by a systems thinking framework and guided by contemporary curricular theories on self-directed and interprofessional learning. Extensive consultations with stakeholders were undertaken. Alignment with relevant national level documents and curricular frameworks was ensured. RESULTS The systems thinking approach provided first, an experience of applying thinking tools for a deeper understanding of how various parts of this micro-curriculum and subsystems should be integrated. Second, applying the toolkit uncovered tension points on which leverage could optimise future enhancements. Eighteen types of health professions were recruited including 105 general practitioners and 253 healthcare practitioners from a range of disciplines. CONCLUSION Systems thinking allows for the identification of various interacting elements within the curriculum to be considered as part of an integrated whole. Insights from this model could inform the design of similar innovative curricula.

Abstract
Exciton polaritons (polaritons herein) in transition-metal dichalcogenide monolayers have attracted significant attention due to their potential for polariton-based optoelectronics. Many of the proposed applications rely on the ability to trap polaritons and to reach macroscopic occupation of their ground energy state. Here, we engineer a trap for room-temperature polaritons in an all-dielectric optical microcavity by locally increasing the interactions between the WS_{2} excitons and cavity photons. The resulting confinement enhances the population and the first-order coherence of the polaritons in the ground state, with the latter effect related to dramatic suppression of disorder-induced inhomogeneous dephasing. We also demonstrate efficient population transfer into the trap when optically injecting free polaritons outside of its periphery.

Abstract
BACKGROUND Pancreatic cancer is the second most frequent cause of death among all forms of cancer in Germany with more than 19,000 deaths per year. The evaluation of the nationwide clinical cancer register aims to depict the reality of treatment and to improve the quality of treatment in the future by targeted analyses. METHOD The data from the clinical cancer register of Brandenburg-Berlin for the diagnosis years 2001-2017 were analyzed with respect to the treatment of pancreatic cancer. Data from patients resident in the State of Brandenburg were evaluated with respect to epidemiological and therapeutic parameters. RESULTS A total of 5418 patients with pancreatic cancer were documented in the register from 2001 to 2017 and 49.6% of the patients were diagnosed as having the Union for International Cancer Control (UICC) stage IV. A pancreas resection was carried out in 26.4% of the cases. In cases of cancer of the head of the pancreas the most frequent procedure was a pylorus-preserving resection with 51.8% and a pancreatectomy was carried out in 9.4%. The R0 resection rate of all pancreatic cancers in the period from 2014 to 2017 was 61.9%. After R0 resection the 5‑year survival was 19%. Relevant multivariate survival factors were age, UICC stage and the residual (R) tumor classification. The case numbers per hospital had no influence on the absolute survival of patients operated on in the State of Brandenburg. CONCLUSION The treatment reality in the State of Brandenburg for patients with pancreatic cancer corresponds to the results of international publications with respect to the key performance indicators investigated. A qualitative internationally comparable treatment of these patients is also possible in nonmetropolitan regions.

Abstract
BACKGROUND Pharmaceutical care for non-communicable diseases (NCD) in Indonesia needs improvement especially in provinces like Kalimantan Selatan (Kalsel) with increasing NCD prevalence. This research explored possible improvements for Kalsel pharmacists NCD Continuing Professional Development (CPD) programmes. OBJECTIVES The study aims to identify Kalsel pharmacists' engagement with, experiences of, and expectations for NCD-focused CPD activities, and CPD stakeholders' views on these expectations. METHODS This sequential mixed-methods study used a quantitative survey to map Kalsel pharmacists' CPD engagement and preferences. The survey findings, and Kalsel pharmacists' knowledge and skills in NCD management, were further explored in four geographically-diverse focus group discussions (FGDs). Triangulated findings from the survey and FGDs were presented to pharmacist CPD stakeholders in a modified Nominal Group Technique (NGT) discussion, resulting in a prioritised list of CPD activities and allocation of local leadership for each activity. RESULTS The survey response rate was 51% (249/490) with fair representation of the geographic spread. CPD sessions were seen as a social event to network with colleagues (34%) and improve knowledge (31%). Major hindrances for participation were work commitments (25%) and travel needs (22%). Most participants (64%), especially the more senior, preferred explicitly interactive CPD formats (adjusted odds ratio 0.94 for each additional year from graduation; 95% confidence interval 0.89-0.99; p = 0.036). The FGDs identified challenges in managing NCD, strengths and gaps in NCD knowledge, and preferences for NCD CPD. The modified NGT produced 12 actions which five major stakeholders agreed to lead. CONCLUSIONS An explicitly interactive NCD CPD programme based on a community of practice model and supported by blended learning is likely to be most effective for pharmacists in the Kalimantan Selatan province of Indonesia. A co-designed multi-stakeholder systems-based approach to CPD programme, as used in this study, is likely to increase the engagement and success of the programme.

Abstract
Funding Acknowledgements
Type of funding sources: Public grant(s) – National budget only. Main funding source(s): Swiss Cancer Research
Background
Exercise is an effective therapy for cancer patients to reduce fatigue and to improve health-related quality of life and physical function. Yet, cancer patients often do not meet physical activity guidelines.
Purpose
To understand why recommendations are not met, we aimed at identifying facilitators and barriers to supervised, centre-based exercise within a cardio-oncologic rehabilitation (CORE) programme and to unsupervised, home-based exercise as well as strategies used to manage these barriers.
Methods
Breast cancer patients who had completed a CORE programme at a Swiss tertiary centre were recruited. Semi-structured interviews were conducted with subsequent thematic analysis.
Results
Of 37 eligible breast cancer patients, 19 patients (mean age 48.9±9.7 years) participated to our invitation. Facilitators for centre-based exercise were social support, committedness and provision of structured exercise. Barriers towards centre-based exercise included physical and environmental barriers, while psychological barriers were reported predominantly for home-based exercise. Strategies to manage barriers included the adaptation of training circumstances, behaviour change strategies and strategies to deal with side effects.
Conclusions
Our results support the importance of providing CORE programmes and suggest that a special focus should be directed at the transition from supervised to self-organized exercise in order to enhance long-term exercise participation.

Abstract
Optical trapping has been proven to be an effective method of separating exciton-polariton condensates from the incoherent high-energy excitonic reservoir located at the pumping laser position. This technique has significantly improved the coherent properties of exciton-polariton condensates, when compared to a quasi-homogeneous spot excitation scheme. Here, we compare two experimental methods on a sample, where a single spot excitation experiment allowed us only to observe photonic lasing in the weak coupling regime. In contrast, the ring-shaped excitation resulted in the two-threshold behavior, where an exciton-polariton condensate manifests itself at the first and photon lasing at the second threshold. Both lasing regimes are trapped in an optical potential created by the pump. We interpret the origin of this confining potential in terms of repulsive interactions of polaritons with the reservoir at the first threshold and as a result of the excessive free-carrier induced refractive index change of the microcavity at the second threshold. This observation offers a way to achieve multiple phases of photonic condensates in samples, e.g., containing novel materials as an active layer, where two-threshold behavior is impossible to achieve with a single excitation spot.

Abstract
OBJECTIVES Chronic pain (CP) impacts individuals and society and is the leading cause of disability globally. Pain education interventions are often evaluated in patients and health professional students, but not in non-health student groups. Increasing knowledge of pain may facilitate shifts in attitudes and beliefs towards sufferers. We report on changes in pain knowledge, attitudes and beliefs of predominantly non-health-related tertiary degree students participating in online education. METHODS Quantitative cohort study design. Students reported demographics and completed the Chronic Pain Myth Scale and 12-item Neurophysiology of Pain Questionnaire (NPQ) before (T1) and after (T2) the 7-week online module at The University of Sydney in 2020. RESULTS Twenty-two students undertaking predominantly non-health-related bachelor's degrees (16.5% response rate, 90.9% female, mean = 19.5 years) participated. NPQ scores increased from 47.3% to 62.9%. Attitudes and beliefs towards biopsychosocial impact improved (p < 0.027) but not towards individuals suffering from CP or treatment of CP. A negative correlation was found between age and people suffering from CP (ρ = -0.437, p < 0.042) and age and towards treatment of CP; ρ = -0.556, p < 0.007) at T2. CONCLUSION Completing the elective online module resulted in improved knowledge and biopsychosocial attitudes towards CP in this predominantly non-health cohort, as reported in health and patient cohorts.

Abstract
OBJECTIVE To determine the effectiveness of TENS at relieving pain and improving physical function as compared to placebo TENS, and to determine its safety, in patients with knee osteoarthritis. METHODS Multi-centre, parallel, 1:1 randomized, double-blind, placebo-controlled clinical trial conducted in six outpatient clinics in Switzerland. We included 220 participants with knee osteoarthritis recruited between October 15, 2012, and October 15, 2014. Patients were randomized to 3 weeks of treatment with TENS (n = 108) or placebo TENS (n = 112). Our pre-specified primary endpoint was knee pain at the end of 3-weeks treatment assessed with the WOMAC pain subscale. Secondary outcome measures included WOMAC physical function subscale and safety outcomes. RESULTS There was no difference between TENS and placebo TENS in WOMAC pain at the end of treatment (mean difference -0.06; 95%CI -0.41 to 0.29; P = 0.74), nor throughout the trial duration (P = 0.98). Subgroup analyses did not indicate an interaction between patient/treatment characteristics and treatment effect on WOMAC pain at the end of treatment (P-interaction ≥0.22). The occurrence of adverse events was similar across groups, with 10.4% and 10.6% of patients reporting events in the TENS and placebo TENS groups, respectively (P = 0.95). No relevant differences were observed in secondary outcomes. CONCLUSIONS TENS does not improve knee osteoarthritis pain when compared to placebo TENS. Therapists should consider other potentially more effective treatment modalities to decrease knee osteoarthritis pain and facilitate strengthening and aerobic exercise. Our findings are conclusive and further trials comparing TENS and placebo TENS in this patient population are not necessary.

Abstract
Abstract
Aim
The COVID19 pandemic has caused oncological services worldwide to face unprecedented challenges resulting in treatment disruptions for cancer patients requiring surgery. Hepatopancreatico-biliary cancers are characterised by a low resectability rate and rapid progression. This study aims to assess the effectiveness of a prioritisation policy for this cohort of patients during the initial COVID19 outbreak.
Method
The prioritisation policy and triage system are described in detail. Patients undergoing surgery between April-July 2020 (COVID period) were compared to a control group from the preceding year. Statistical analysis was carried out to evaluate timeliness of treatment, peri-operative characteristics and short-outcomes.
Results
Patient selection was restructured to prioritise patients with performance status of < 2 with presence of cancer complications, borderline resectable- or biologically aggressive disease. Where feasible, neoadjuvant therapy was advocated. An elective safe corridor pathway was established to reduce the risk of COVID19 infection. During the COVID19 and pre-COVID19 period, 94 and 115 patients underwent surgery, respectively. No patients contracted COVID19 post-operatively. There were less patients with ASA≥3 during the COVID19 period vs. pre-COVID19 (12.8% vs. 34.2%; p < 0.001). Median time between referral and surgery was greater during the COVID19 compared to the pre-COVID19 period, at 64 days vs. 49 days, respectively (p = 0.023). Despite this difference no NHS waiting list breaches occurred. Incidence of postoperative complications were comparable between groups.
Conclusions
The outlined prioritisation policy for oncological hepatopancreatico-biliary resections was effective in providing safe surgery during the COVID-19 outbreak. Whether the observed delay in treatment will affect long-term outcomes remains to be seen

Abstract
Engineering non-linear hybrid light-matter states in tailored lattices is a central research strategy for the simulation of complex Hamiltonians. Excitons in atomically thin crystals are an ideal active medium for such purposes, since they couple strongly with light and bear the potential to harness giant non-linearities and interactions while presenting a simple sample-processing and room temperature operability. We demonstrate lattice polaritons, based on an open, high-quality optical cavity, with an imprinted photonic lattice strongly coupled to excitons in a WS2 monolayer. We experimentally observe the emergence of the canonical band-structure of particles in a one-dimensional lattice at room temperature, and demonstrate frequency reconfigurability over a spectral window exceeding 85 meV, as well as the systematic variation of the nearest-neighbour coupling, reflected by a tunability in the bandwidth of the p-band polaritons by 7 meV. The technology presented in this work is a critical demonstration towards reconfigurable photonic emulators operated with non-linear photonic fluids, offering a simple experimental implementation and working at ambient conditions.

Abstract
BACKGROUND Compared to open surgery, minimally invasive liver resection has improved short term outcomes. It is however technically more challenging. Navigated image guidance systems (IGS) are being developed to overcome these challenges. The aim of this systematic review is to provide an overview of their current capabilities and limitations. METHODS Medline, Embase and Cochrane databases were searched using free text terms and corresponding controlled vocabulary. Titles and abstracts of retrieved articles were screened for inclusion criteria. Due to the heterogeneity of the retrieved data it was not possible to conduct a meta-analysis. Therefore results are presented in tabulated and narrative format. RESULTS Out of 2015 articles, 17 pre-clinical and 33 clinical papers met inclusion criteria. Data from 24 articles that reported on accuracy indicates that in recent years navigation accuracy has been in the range of 8-15 mm. Due to discrepancies in evaluation methods it is difficult to compare accuracy metrics between different systems. Surgeon feedback suggests that current state of the art IGS may be useful as a supplementary navigation tool, especially in small liver lesions that are difficult to locate. They are however not able to reliably localise all relevant anatomical structures. Only one article investigated IGS impact on clinical outcomes. CONCLUSIONS Further improvements in navigation accuracy are needed to enable reliable visualisation of tumour margins with the precision required for oncological resections. To enhance comparability between different IGS it is crucial to find a consensus on the assessment of navigation accuracy as a minimum reporting standard.

Abstract
Due to their capacity to differentiate into the chondrogenic lineage, adipose-derived stromal/stem cells (ASC) are a promising source of therapeutically relevant cells for cartilage tissue regeneration. Their differentiation potential, however, varies between patients. In our study, we aim to stimulate ASC towards a more reliable chondrogenic phenotype using photobiomodulation (PBM). LED devices of either blue (475 nm), green (516 nm) or red (635 nm) light were used to treat human ASC from donors of varying chondrogenic potential. The treatment was applied either once during the 2D expansion phase or repeatedly during the 3D differentiation phase. Chondrogenic differentiation was assessed via pellet size, GAG/DNA content, histology and gene expression analysis. Reactions to PBM were found to be wavelength-dependent and more pronounced when the treatment was applied during expansion. Donors were assigned to responder categories according to their response to the treatment during expansion, whereby good responders were mainly donors with low intrinsic chondrogenic potential. Exposed to light, they revealed a particularly high relative increase in pellet size (more than twice the size of untreated controls after red light PBM), intense collagen type II immunostaining (low/absent in untreated controls) and activation of otherwise absent COL2A1 expression. Conversely, on a donor with high intrinsic chondrogenic potential, light had adverse effects. When applied with shorter wavelengths (blue, green), it led to reduced pellet size, GAG/DNA content and collagen type II immunostaining. However, when PBM was applied in 3D, the same donor was the only one to react with increased differentiation to all three wavelengths. We were able to demonstrate that PBM can be used to enhance or hamper chondrogenesis of ASC, and that success depends on treatment parameters and intrinsic cellular potential. The improvement of chondrogenesis in donors with low intrinsic potential highlights PBM as potent tool for cell-based cartilage regeneration. Its cost-effectiveness and ease of use make for an attractive treatment option to enhance the performance of ASC in cartilage tissue engineering.

Abstract
We report on novel exciton-polariton routing devices created to study and purposely guide light-matter particles in their condensate phase. In a codirectional coupling device, two waveguides are connected by a partially etched section that facilitates tunable coupling of the adjacent channels. This evanescent coupling of the two macroscopic wave functions in each waveguide reveals itself in real space oscillations of the condensate. This Josephson-like oscillation has only been observed in coupled polariton traps so far. Here, we report on a similar coupling behavior in a controllable, propagative waveguide-based design. By controlling the gap width, channel length, or propagation energy, the exit port of the polariton flow can be chosen. This codirectional polariton device is a passive and scalable coupler element that can serve in compact, next generation logic architectures.

Abstract
OBJECTIVE Community pharmacists are highly accessible healthcare professionals, whose regular contact with patients provides ongoing opportunities to improve medication safety and promote medication adherence. This study investigates whether patients who experience low service quality in community pharmacies are less adherent to their regular medications. METHODS Eight Australian pharmacies were recruited, 5 self-identified as having a price promotion business strategy and 3 with a service-focused business strategy. Patients taking regular prescribed medicines who had previously attended the pharmacy completed e-surveys in-store with measures of perceived service quality (pSQ) and self-reported adherence. Multivariate regression using multilevel modelling with bootstrapping was used to explore the relationships between variables. RESULTS Surveys were completed by 319 respondents. Attending pharmacies with a price promotion business strategy was predictive of lower pSQ and poor medication adherence. The between-pharmacy slope of the relationship between pSQ and adherence was 2.25 (with 95 % confidence intervals = 1.50, 2.86) and was highest in pharmacies with lowest pSQ. CONCLUSION This study highlights that when patients experience low service quality, in community pharmacies they are more likely to report poor adherence to their regular prescribed medicines. PRACTICE IMPLICATIONS Community pharmacies need to be designed and managed to allow pharmacists to provide high levels of patient-centred care.

Abstract
PURPOSE Medical combination therapy of pulmonary arterial hypertension (PAH) may alleviate the drawbacks of monotherapy by avoiding drug tolerance and by increasing effectiveness, as shown by the combination of ambrisentan and tadalafil (AMBITION trial). The present ex-vivo study evaluated the combination of the endothelin receptor antagonists (ERA) macitentan and bosentan with the phosphodiesterase-5 (PDE-5) inhibitor vardenafil in pulmonary arteries from patients suffering from terminal lung disease as a model of PAH. METHODS Segments of the pulmonary vessels were excised from resected lungs of patients requiring lung transplantation (LTX). Contraction of pulmonary arteries (PA) was elicited by consecutive dose-response curves of endothelin-1 (ET-1) followed by norepinephrine (NE) to allow inhibition by different pathways. Forces were measured isometrically in an organ bath in the presence and absence of ERA and PDE-5 inhibitors and their combination. RESULTS PA of 38 patients were examined between October 2016 and November 2019. Bosentan (1E-7 M) and macitentan (1E-8 M, 3E-8 M, 1E-7 M) inhibited ET-1 induced contractions, whereas vardenafil (1E-6 M, 3E-6 M, 1E-5 M) inhibited only the NE induced part of the contractions. Vardenafil enhanced bosentan-induced inhibition of vasoconstriction in a dose-dependent fashion. Combination effects exceeded single bosentan at 3E-6 M and 1E-5 M vardenafil, and they exceeded single vardenafil at the lower vardenafil concentrations. Macitentan showed a more pronounced inhibition than bosentan regardless of the lower concentrations. Accordingly, combination effects with vardenafil resembled those of macitentan alone. CONCLUSIONS Macitentan and bosentan were potent antagonists of vasoconstriction in PA of LTX patients. The benefit of drug combinations was demonstrated at selected concentrations only owing to a narrow therapeutic range of vardenafil in this ex-vivo model. These results suggest the utility of drug combinations other than the established pair of ambrisentan and tadalafil in PAH treatment but also make a case for a further assessment of vasodilator properties of drugs complementing ERA.

Abstract
Intensity squeezing-i.e., photon number fluctuations below the shot-noise limit-is a fundamental aspect of quantum optics and has wide applications in quantum metrology. It was predicted in 1979 that intensity squeezing could be observed in resonance fluorescence from a two-level quantum system. However, its experimental observation in solid states was hindered by inefficiencies in generating, collecting, and detecting resonance fluorescence. Here, we report the intensity squeezing in a single-mode fiber-coupled resonance fluorescence single-photon source based on a quantum dot-micropillar system. We detect pulsed single-photon streams with 22.6% system efficiency, which show sub-shot-noise intensity fluctuation with an intensity squeezing of 0.59 dB. We estimate a corrected squeezing of 3.29 dB at the first lens. The observed intensity squeezing provides the last piece of the fundamental picture of resonance fluorescence, which can be used as a new standard for optical radiation and in scalable quantum metrology with indistinguishable single photons.

Abstract
BACKGROUND Pancreaticoduodenectomy is the only curative treatment option for patients with resectable ampullary adenocarcinoma (AA). Excellent disease free survival (DFS) can be achieved in patients with clear resection margins but it is poorly understood which patients are at increased risk of recurrence and hence would benefit from adjuvant chemotherapy. There is evolving evidence that the anatomical location of incomplete resection margins influences DFS in pancreatic adenocarcinoma. It is unknown if this also pertains to AA and therefore this study aimed to assess individual resection margin status and other predictors of DFS in AA. MATERIAL & METHODS Consecutive patients undergoing pancreaticoduodenectomy for AA at our institution from 1996 to 2017 were analysed. Pancreas neck, posterior and superior mesenteric vein margins were assessed individually. Cox proportional hazards modelling was used to identify predictors of 5-year DFS. Factors with p < 0.1 on univariate analysis were included for multivariate analysis. RESULTS Analysis of 104 patients revealed median OS and DFS of 56 and 34 months, respectively. Predictors associated with worse DFS on multivariate analysis were T3-stage (HR 3.6, p = 0.048), N1 (HR 2.9, p = 0.01) and N2 -stage (HR 3.6, p = 0.006), R1 status at the posterior margin (HR 3.0, p = 0.009) and a visible mass on CT (HR 2.0, p = 0.039). CONCLUSION Routine histopathological assessment of individual resection margins may aid in predicting recurrence of AA. Future studies to assess if routine mesopancreas excision during pancreaticoduodenectomy can reduce the incidence of R1 status at the posterior margin are warranted.

Abstract
The large oscillator strength of excitons in transition metal dichalcogenide layers facilitates the formation of exciton-polariton resonances for monolayers and van-der-Waals heterostructures embedded in optical microcavities. Here, we show, that locally changing the number of layers in a WSe2/hBN/WSe2 van-der-Waals heterostructure embedded in a monolithic, high-quality-factor cavity gives rise to a local variation of the coupling strength. This effect yields a polaritonic stair case potential, which we demonstrate at room temperature. Our result paves the way towards engineering local polaritonic potentials at length scales down to atomically sharp interfaces, based on purely modifying its real part contribution via the coherent light-matter coupling strength g.

Abstract
Interacting Bosons in artificial lattices have emerged as a modern platform to explore collective manybody phenomena and exotic phases of matter as well as to enable advanced on-chip simulators. On chip, exciton–polaritons emerged as a promising system to implement and study bosonic non-linear systems in lattices, demanding cryogenic temperatures. We discuss an experiment conducted on a polaritonic lattice at ambient conditions: We utilize fluorescent proteins providing ultra-stable Frenkel excitons. Their soft nature allows for mechanically shaping them in the photonic lattice. We demonstrate controlled loading of the coherent condensate in distinct orbital lattice modes of different symmetries. Finally, we explore the self-localization of the condensate in a gap-state, driven by the interplay of effective interaction and negative effective mass in our lattice. We believe that this work establishes organic polaritons as a serious contender to the well-established GaAs platform for a wide range of applications relying on coherent Bosons in lattices. Many studies of polariton condensates have been limited to low temperatures. Here the authors demonstrate ambient polariton condensation in lattices using organic traps that profit from the stability of organic excitons and the large Rabi splitting.
