Achievement of Target Gain Larger than Unity in an Inertial Fusion Experiment. PHYSICAL REVIEW LETTERS 2024; 132:065102. [PMID: 38394591 DOI: 10.1103/physrevlett.132.065102] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/27/2023] [Accepted: 01/03/2024] [Indexed: 02/25/2024]
Abstract
On December 5, 2022, an indirect drive fusion implosion on the National Ignition Facility (NIF) achieved a target gain G_{target} of 1.5. This is the first laboratory demonstration of exceeding "scientific breakeven" (or G_{target}>1) where 2.05 MJ of 351 nm laser light produced 3.1 MJ of total fusion yield, a result which significantly exceeds the Lawson criterion for fusion ignition as reported in a previous NIF implosion [H. Abu-Shawareb et al. (Indirect Drive ICF Collaboration), Phys. Rev. Lett. 129, 075001 (2022)PRLTAO0031-900710.1103/PhysRevLett.129.075001]. This achievement is the culmination of more than five decades of research and gives proof that laboratory fusion, based on fundamental physics principles, is possible. This Letter reports on the target, laser, design, and experimental advancements that led to this result.

Abstract
Persons with HIV (PWH) are at increased risk for bacterial infections, and previous publications document an increased risk for invasive meningococcal disease (IMD) in particular. This analysis provides evidence that PWH face a 6-fold increase in risk for IMD based on Active Bacterial Core surveillance data collected during 2009-2019.

Lawson Criterion for Ignition Exceeded in an Inertial Fusion Experiment. PHYSICAL REVIEW LETTERS 2022; 129:075001. [PMID: 36018710 DOI: 10.1103/physrevlett.129.075001] [Citation(s) in RCA: 46] [Impact Index Per Article: 23.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/25/2022] [Revised: 06/24/2022] [Accepted: 07/06/2022] [Indexed: 06/15/2023]
Abstract
For more than half a century, researchers around the world have been engaged in attempts to achieve fusion ignition as a proof of principle of various fusion concepts. Following the Lawson criterion, an ignited plasma is one where the fusion heating power is high enough to overcome all the physical processes that cool the fusion plasma, creating a positive thermodynamic feedback loop with rapidly increasing temperature. In inertially confined fusion, ignition is a state where the fusion plasma can begin "burn propagation" into surrounding cold fuel, enabling the possibility of high energy gain. While "scientific breakeven" (i.e., unity target gain) has not yet been achieved (here target gain is 0.72, 1.37 MJ of fusion for 1.92 MJ of laser energy), this Letter reports the first controlled fusion experiment, using laser indirect drive, on the National Ignition Facility to produce capsule gain (here 5.8) and reach ignition by nine different formulations of the Lawson criterion.

Abstract
Abstract
Background
Little is known about unwarranted variations in care and outcomes of patients who undergo surgical repair for type A acute aortic dissection(TAAD). We aim to investigate decade-long trends in TAAD surgical repair in England.
Method
Retrospective review of the National Institute for Cardiovascular Outcomes Research (NICOR) National Adult Cardiac Surgery Audit (NACSA) registry from January 2009 to December 2018 , which prospectively collects demographic and peri-operative clinical information for all adult cardiac surgery procedures in the UK.
Results
Over the 10-year period,3,686 TAAD patients underwent surgical repair in England. A steady doubling in the overall number of operations conducted in England was observed from 237 cases recorded in 2009 to 510 in 2018. Number of procedures per hospital per year also doubled, from 10 in 2009 to 21 in 2018. The risk profile of the operated patients remained unchanged. Overall, in-hospital mortality was 17.4% with a trend toward lower mortality in the most recent years (from 22.8% in 2009 to 14.7% in 2018). There was a significant variation in operative mortality across regions with a trend towards lower mortality in regions with a high-volume hospital.
Conclusions
Surgery is the only treatment for acute TAAD but is associated with high mortality. Prompt diagnosis and referral to a specialist center is paramount. The number of operations conducted in England has doubled in 10 years and the associated survival following surgery has improved. Regional variations exist in service provision with a trend towards better survival in high volume centers.

The burden of COVID-19 on pharmacists. J Am Pharm Assoc (2003) 2021; 61:e61-e64. [PMID: 33189556 PMCID: PMC7580693 DOI: 10.1016/j.japh.2020.10.013] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2020] [Revised: 09/23/2020] [Accepted: 10/18/2020] [Indexed: 12/16/2022]
Abstract
The unprecedented changes brought about by the global coronavirus disease 2019 (COVID-19) pandemic have had important impacts on society. The pandemic has provided an opportunity to highlight the crucial role pharmacists play in the provision of health care. The critical and unique role of pharmacists in pandemics and other disasters has been highlighted in the past (severe acute respiratory syndrome and Ebola outbreaks) and more recently with reports of the contributions of pharmacists during the global COVID-19 pandemic. Many reports have documented that health care professionals are experiencing significant psychological morbidity as a result of providing essential care and services during the global COVID-19 pandemic. In these reports, pharmacists are not well represented, and, therefore, it is essential to understand the impact of COVID-19 on pharmacists across multiple practice settings. This is particularly true as the experiences of pharmacists working through previous pandemics and disasters, and the associated psychological burden, are likely to offer insights and be useful in supporting the psychological well-being of pharmacists during the global COVID-19 pandemic. Research into the effect of the global COVID-19 pandemic on pharmacists should improve the understanding of the impact and the psychological morbidity associated with their role as frontline health care professionals.

Risk factors for non-communicable diseases related to obesity among first- and second-generation Bangladeshi migrants living in north-east or south-east England. Int J Obes (Lond) 2021; 45:1588-1598. [PMID: 33947968 PMCID: PMC8236404 DOI: 10.1038/s41366-021-00822-5] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/17/2020] [Revised: 02/18/2021] [Accepted: 04/08/2021] [Indexed: 02/03/2023]
Abstract
BACKGROUND Obesity is a global burden, which significantly increases the risk of non-communicable diseases (NCDs). More than a quarter of adults in the United Kingdom are obese, but prevalence varies by ethnicity, and South Asians have the largest burden of NCDs. This paper assesses how sex, generation, and region interplay to vary the predisposition to obesity-related (OR) NCDs among UK Bangladeshis. METHODS We used National Institute for Health and Care Excellence suggested grading for combining body mass index and waist circumference to define populations at risk of OR-NCDs. Data from 517 adults of Bangladeshi origin from a cross-sectional study (March 2013 to April 2015) were analysed. Male and female participants from London and north-east England were equally sampled including: (1) adult migrants, who came to the UK aged >16 years; (2) child migrants, who came to the UK aged ≤16 years; and (3) second-generation Bangladeshis (who were born and brought up in the UK). A generalised estimating equation using a binomial distribution and a logit link was used to explore the relationship between the binary outcome of being 'at risk of OR-NCDs' and associated factors. RESULTS Females, married individuals, those living in London, the second-generation, and those of lower self-assessed financial status, with low acculturation status, or who did not walk daily for at least 20 min were more likely to develop OR-NCDs. A striking sex difference was found with more females prone to OR-NCD risk in the north-east than in London. CONCLUSIONS Our study observed important inter- and intra-regional inequality in OR-NCD risk which worsens the health of ethnic minorities and widens inequality.

Abstract
Background Academic and public health partnerships are a critical component of the Ending the HIV Epidemic: A Plan for America (EHE). The Enhanced HIV/AIDS Reporting System (eHARS) is a standardized document-based surveillance database used by state health departments to collect and manage case reports, lab reports, and other documentation on persons living with HIV. Innovative analysis of this data can inform targeted, evidence-based interventions to achieve EHE objectives. We describe the development of a distributed data network strategy at an academic institution in partnership with public health departments to identify geographic differences in time to HIV viral suppression after HIV diagnosis using eHARS data. Figure 1. Distributed Data Network ![]()
Methods This project was an outgrowth of work developed at the University of Alabama at Birmingham Center for AIDS Research (UAB CFAR) and existing relationships with the state health departments of Alabama, Louisiana, and Mississippi. At a project start-up meeting which included study investigators and state epidemiologists, core objectives and outcome measures were established, key eHARS variables were identified, and regulatory and confidentiality procedures were examined. The study methods were approved by the UAB Institutional Review Board (IRB) and all three state health department IRBs. Results A common data structure and data dictionary across the three states were developed. Detailed analysis protocols and statistical code were developed by investigators in collaboration with state health departments. Over the course of multiple in-person and virtual meetings, the program code was successfully piloted with one state health department. This generated initial summary statistics, including measures of central tendency, dispersion, and preliminary survival analysis. Conclusion We developed a successful academic and public health partnership creating a distributed data network that allows for innovative research using eHARS surveillance data while protecting sensitive health information. Next, state health departments will transmit summary statistics to UAB for combination using meta-analytic techniques. This approach can be adapted to inform delivery of targeted interventions at a regional and national level. Disclosures All Authors: No reported disclosures

Abstract
Objectives To inform the design of a clinical trial of a targeted screening programme for relatives of individuals affected by thoracic aortic disease, we performed a consensus exercise as to the acceptability of screening, the optimal sequence and choice of tests, long-term patient management, and choice of trial design. Methods Working with the Aortic Dissection Awareness UK & Ireland patient association, we performed a Delphi exercise with clinical experts, patients, and carers, consisting of three rounds of consultation followed by a final multi-stakeholder face-to-face workshop. Results Thirty-five experts and 84 members of the public took part in the surveys, with 164 patients and clinicians attending the final workshop. There was substantial agreement on the need for a targeted screening pathway that would employ a combined approach (imaging + genetic testing). The target population would include the first- and second-degree adult (> 15 years) relatives, with no upper age limit of affected patients. Disagreement persisted about the screening process, sequence, personnel, the imaging method to adopt, computed tomography (CT) scan vs magnetic resonance imaging (MRI), and the specifics of a potential trial, including willingness to undergo randomisation, and measures of effectiveness and acceptability. Conclusion A Delphi process, initiated by patients, identified areas of uncertainty with respect to behaviour, process, and the design of a targeted screening programme for thoracic aortic disease that requires further research prior to any future trial.

A wake-up call for physical activity promotion in Australia: results from a survey of Australian nursing and allied health professionals. AUST HEALTH REV 2019; 43:165-170. [PMID: 29224589 DOI: 10.1071/ah16240] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2016] [Accepted: 10/09/2017] [Indexed: 11/23/2022]
Abstract
Objective Nursing and allied health professionals (AHPs) are in an ideal position to promote physical activity (PA) as part of their health care provision. The aim of this study was to investigate current promotion and knowledge of PA among people in these disciplines. Methods A cross-sectional online survey of practicing Australian physiotherapists, nurses, exercise physiologists, occupational therapists, dietitians and pharmacists was conducted in 2016. Results A total of 433 nurses and AHPs completed the survey. All disciplines agreed that providing PA advice was part of their role, although nurses were less likely to agree. All disciplines felt they had the skills to promote PA but nurses were more likely to report a lack of time as a barrier. Physiotherapists and exercise physiologists were more confident giving PA advice to patients. Most health professionals (68%) were aware of the PA guidelines, although only 16% were accurately able to describe all relevant components. In logistic regression modelling, women and those working in public hospitals were less likely to encourage PA. Awareness of the PA guidelines doubled the odds of encouraging PA in patients (odds ratio 2.01, 95% confidence interval 1.18-3.43). Conclusions Australian nurses and AHPs perceive that PA promotion is part of their role, however few have specific knowledge of the PA guidelines. To increase PA promotion by nurses and AHPs awareness of the PA guidelines appears to be essential. What is known about the topic? Nurses and AHPs are in an ideal position to promote PA, although there is limited evidence of their PA promotion and knowledge. What does the paper add? Australian nurses and AHPs are confident and think it is feasible to promote PA to patients in several healthcare settings but many lack sufficient PA knowledge, limiting their PA promotion. What are the implications for practitioners? Increasing PA knowledge of nurses and AHPs could generate increased levels of PA in the Australian population and improve national health and wellbeing.

Abstract
Background Alopecia Areata (AA) is an autoimmune condition that is characterised by non-scarring hair loss. Its aesthetic repercussions can lead to profound changes in psychological well-being. Although physical activity (PA) has been associated with better mental health outcomes in diverse populations, the association in individuals with AA has not been established. The aim of this study was to examine the associations between PA and mental health outcomes in individuals with AA to inform intervention strategies for this specific population. Methods A cross-sectional study was conducted among individuals who were diagnosed with AA. A total of 83 respondents aged (40.95 ± 13.24 years) completed a self-report questionnaire consisting of International Physical Activity Questionnaire-Short Form (IPAQ-SF) and the Depression and Anxiety Stress Scale (DASS-21). Three-way contingency Chi-square analyses were used to determine the associations between PA, mental health outcomes and participants with hair loss of more than 50% on the scalp. Results 81.9% of the participants did not meet PA guidelines. Participants with hair loss of more than 50% on the scalp, and who did not meet PA guidelines, were significantly more likely to experience symptoms of severe depression (p = .003), moderate anxiety (p = .04) and mild stress (p = .003) than those who met guidelines Conclusion Findings suggest that increased PA participation in AA individuals with severe hair loss is associated with improved mental health status. Intervention efforts for this specific population should consider barriers and enablers to PA participation as they face challenges that differ from the general population.

Abstract
OBJECTIVE Modafinil is a psychostimulant that has been shown to enhance cognitive and physical performance. Given its long half-life, it may provide operational advantages if it can improve tolerance to the deleterious effects of prolonged mental exertion. METHODS Physically active males (n = 13, 23 ± 4 years, peak oxygen consumption 45.3 ± 3.2 ml kg-1 min-1 ) took part in a placebo controlled, double-blind randomised crossover study to investigate if modafinil could improve cognitive and physical performance following a prolonged period of mental exertion. RESULTS Overall modafinil improved performance on a task of executive function over time (p = .023; η2 = 0.376) but did not improve subsequent physical endurance performance (mean difference 2.3 ± 11.5%, p = .50), despite improvement in 10 out of the 13 participants. Task demand was reported as lower with modafinil, although perceptual measures of fatigue and motivation did not consistently improve. Heart rate during submaximal exercise was higher (134 ± 11 vs. 119 ± 14 bpm, p < .001), and sleep was reduced (5.5 ± 1.4 vs. 7.5 ± 1.4 hr, p < .001) and less efficient (64 ± 13 vs. 83 ± 9%, p < .001) compared with placebo. CONCLUSIONS Operationally, modafinil may offer advantages given the established longer half-life than other psychostimulants, despite the variable response. The impact of higher heart rates and disrupted sleep on performance must also be considered.

Dilution and microfiltration of particulate corticosteroids for spinal epidural injections: impact on drug concentration and agglomerate formation. Anaesthesia 2019; 74:1551-1557.

Abstract
Particulate corticosteroids have been described to lead to greater pain improvement compared with their non-particulate counterparts when used in epidural injections. It is hypothesised that filtering may significantly impact their concentration and long-term efficacy. We investigated if passing particulate suspensions through different commonly-used filters affects drug dosage. Two particulate corticosteroid formulations, triamcinolone acetonide and methylprednisolone acetate, were mixed at different concentrations with either bupivacaine hydrochloride or 0.9% sodium chloride. Solutions were passed through a 5-μm and a 0.2-μm filter. Mass spectroscopy results indicated a complete loss of corticosteroid from the solutions using both filters, and light microscopy imaging demonstrated agglomerate formation, suggesting that filtering interferes with drug dosage. The choice of diluents must also be considered to reduce large agglomerate formation. Clinicians should be aware of the consequences of filtering particulate suspensions and carefully consider the selection of diluent when considering treatment plans.

Abstract
AIMS The aims of this study were to report the efficacy of revision surgery for patients with co-infective bacterial and fungal prosthetic joint infections (PJIs) presenting to a single institution, and to identify prognostic factors that would guide management. PATIENTS AND METHODS A total of 1189 patients with a PJI were managed in our bone infection service between 2006 and 2015; 22 (1.85%) with co-infective bacterial and fungal PJI were included in the study. There were nine women and 13 men, with a mean age at the time of diagnosis of 64.5 years (47 to 83). Their mean BMI was 30.9 kg/m2 (24 to 42). We retrospectively reviewed the outcomes of these PJIs, after eight total hip arthroplasties and 14 total knee arthroplasties. The mean clinical follow-up was 4.1 years (1.4 to 8.8). RESULTS The median number of risk factors for PJI was 5.5 (interquartile range (IQR) 3.25 to 7.25). All seven patients who initially underwent debridement and implant retention (DAIR) had a recurrent infection that led to a staged revision. All 22 patients underwent the first of a two-stage revision. None of the nine patients with negative tissue cultures at the second stage had a recurrent infection. The rate of recurrent infection was significantly higher in the presence of multidrug-resistant bacteria (p = 0.007), a higher C-reactive protein (CRP) at the time of presentation (p = 0.032), and a higher number of co-infective bacterial organisms (p = 0.041). The overall rate of eradication of infection after two and five years was 50% (95% confidence interval (CI) 32.9 to 75.9) and 38.9% (95% CI 22.6 to 67), respectively. CONCLUSION The risk of failure to eradicate infection with the requirement of amputation associated with this diagnosis is much higher than in patients with PJI without bacterial and fungal co-infection, and this risk is heightened when the fungal organism is joined by polymicrobial and multidrug-resistant bacterial organisms.

Abstract
Background: Oncology consultations can be overwhelming and information-dense. Consultation audio recordings are an effective method to promote patient participation, improve patients' recall and understanding of medical information, and can increase engagement and support through sharing with family and friends. Innovative m-health technologies such as the SecondEars consultation audio recording mobile app provide a patient-designed and controlled audio recording solution while ensuring security and legal protection for clinicians. To ensure the SecondEars app meets the needs of patients, family, clinicians and hospital administrators, the opinions of stakeholders and end users are integral to the concept and study creation, design, and testing processes. Aim: To use key elements of codesign methodology to develop and test SecondEars, a mobile app that allows patients to audio record their consultations within a clinical oncology setting. Methods: The SecondEars app concept began with consumer suggestions that consultation audio recording be used as standard practice of care using patient-driven (use is controlled/determined by patients) technologies. An app solution was conceived and the concept discussed through engagement of consumers as part of the project and research codesign team. Key health service stakeholders comprising representatives from: legal, information technology (IT), clinical service leads, digital strategy, and health information services (HIS), provided project oversight and core legal and data management requirements. The Scrum management framework was used to structure the codesign process during the development and testing phase. Six workshops were run to facilitate further user input with regard to specific app functionality and design. A wireframe version was developed and tested by the codesign team in the final workshop. Feedback was incorporated into a prototype which was circulated for acceptance testing. Results: Twenty people participated in the stakeholder engagement and workshops, comprising: oncology consumers, researchers, IT, HIS, app developers, and oncology health professionals. Key specifications necessitated that SecondEars be patient-driven, secure and confidential, have clear legal guidelines regarding audio recording sharing, be integrated with medical records, and require minimal upfront and ongoing resources. Seven people tested the prototype app during user acceptance testing and gave positive and constructive feedback. A final version of the app was then made available for clinical testing. Conclusion: The SecondEars consultation audio recording app has been successfully created by and for patients. This app gives patients permission and autonomy to audio record and share their consultations responsibly, while maintaining legal protection for clinicians. This app is currently being tested in a clinical setting prior to conducting an implementation study.

The Quest for Welfare-Friendly Feeding of Broiler Breeders: Effects of Daily vs. 5:2 Feed Restriction Schedules. Poult Sci 2018; 97:368-377.

Abstract
Restricted feeding of broiler breeders is required for improved long-term health and welfare. Because feeding frustration and hunger are major welfare concerns during rearing, many suggestions have been made to decrease the negative feelings of hunger while maintaining suitable growth rates and reproductive health. Non-daily ("skip-a-day") feeding schedules are commonly used around the world to increase portion sizes at meal times while restricting intake but these practices are prohibited in many countries due to welfare concerns on fasting days. We compared birds raised on a non-daily feeding schedule (2 non-consecutive fasting days per week, 5:2), previously suggested as a welfare-friendlier non-daily alternative, to birds raised on daily feed restriction. We found signs of increased physiological stress levels in 5:2 birds, including elevated heterophil to lymphocyte ratios (1.00 for 5:2 vs. 0.75 for daily fed at 12 weeks of age), increased adiposity (0.21% lean body weight [LBW] for 5:2 vs. 0.13% LBW for daily fed), and reduced muscle growth (pectoral muscle 5.94% LBW for 5:2 vs. 6.52% LBW for daily fed). At the same time, 5:2 birds showed signs of lower anxiety before feeding times (activity was reduced from 10.30 in daily fed to 4.85) which may be a result of the lower feed competition associated with larger portion sizes. Although we found no difference in latency to first head movement in tonic immobility between the treatments (136.5 s on average for both groups), 5:2 birds generally showed more interest in a novel object in the home pen which indicated increased risk taking and reduced fear while fasting. The 5:2 birds in this study showed no signs of learning the feeding schedule, and this unpredictability may also increase stress. Taken together, the effects of 5:2 vs. daily feed restriction on the welfare of broiler breeder pullets remain inconclusive and differ between feeding and fasting days. In addition to reducing stress by minimizing the number of fasting days, we suggest that a shift to more predictable schedules may help improve the welfare of broiler breeder pullets.

Abstract
Global usage and expenditure on complementary medicines is increasing. Over 50% of consumers purchase these products from pharmacies and expect pharmacists to provide them with appropriate information regarding efficacy and safety of these products. Internationally, pharmacists have identified their lack of detailed knowledge of the efficacy and safety of these products as a barrier to recommending these products. Currently, little is known about the actual knowledge Australian pharmacists have of these products. This research seeks to determine Australian pharmacists' knowledge of the efficacy and safety of complementary medicines. An online survey was validated and distributed by three professional pharmacy bodies in Australia and online social media to survey Australian pharmacists' knowledge of a selection of complementary medicines that are defined as having therapeutic benefits as per the Australian Therapeutic Guidelines. In total, 535 complete surveys were returned and included in the final analysis. Surveys were predominantly completed by community pharmacists. The mean knowledge score obtained was 62%. There were no statistically significantly different results from pharmacists with a nutritional qualification. Australian pharmacists appear to have a basic knowledge of complementary medicines with a defined clinical effect. Specialised and targeted education focussing on relevant and efficacious complementary medicines with strong clinical evidence base is required.

Surface electromyography can quantify temporal and spatial patterns of activation of intrinsic human foot muscles. J Electromyogr Kinesiol 2018; 39:149-155.

Abstract
Intrinsic foot muscles (IFM) are a crucial component within the human foot. Investigating their functioning can help understand healthy and pathological behaviour of foot and ankle, fundamental for everyday activities. Recording muscle activation from IFM has been attempted with invasive techniques, mainly investigating single muscles. Here we present a novel methodology, to investigate the feasibility of recording physiological surface EMG (sEMG) non-invasively and quantify patterns of activation across the whole plantar region of the foot. sEMG were recorded with a 13 × 5 array from the sole of the foot (n = 25) during two-foot stance, two-foot tiptoe and anterior/posterior sways. Physiological features of sEMG were analysed. During anterior/posterior epochs within the sway task, sEMG patterns were analysed in terms of signal amplitude (intensity) and structure (Sample Entropy) distribution, by evaluating the centre of gravity (CoG) of each topographical map. Results suggest signals are physiological and not affected by loading. Both amplitude and sample entropy CoG coordinates were grouped in one region and overlapped, suggesting that the region with highest amplitude corresponds with the most predictable signal. Therefore, both spatial and temporal features of IFM activation may be recorded non-invasively, providing opportunity for more detailed investigation of IFM function in healthy and patient populations.

Abstract
Previous studies have found that integrating non-dispensing pharmacists in general practice may improve patient safety, improve patient outcomes, deliver health system efficiencies and generate savings. However, the employment of pharmacists in general practice is not common in Australia. A naturalistic study was conducted in the Australian Capital Territory with three general practices, each employing a part-time pharmacist for 12 months. This study reports on stakeholder perspectives of the benefits, barriers and enablers for integrating pharmacists into general practice. Patients, practice staff and community pharmacists that had interacted with a practice pharmacist were asked to complete a self-administered questionnaire. Patient questionnaire respondents (n=44) reported that a practice pharmacist was beneficial and wanted to see this continue. Practice pharmacists were also perceived beneficial by primary healthcare employees surveyed (n=42). Opinions were further explored by individual semi-structured interviews (n=20). The qualitative data explored five themes: perception of the practice pharmacist, collaboration with doctors, pharmacist roles, sustainability and community pharmacy aspects. Patients welcomed improved understanding about their medication, whereas general practice staff appreciated pharmaceutical advice about patients with chronic conditions. Participants discussed options to fund practice pharmacists longer term, which was identified as the main barrier to widespread roll out.

Abstract
Osteoarthritis is a common progressive disease in older adults, and those affected often have impaired physical function, co-existing disease states, and reduced quality of life. In patients with osteoarthritis, pain is reported as a primary cause of mobility limitation, and guidelines recommend a mix of pharmacologic and non-pharmacologic strategies for pain management. The benefits of exercise in the management of osteoarthritis are well established; however, pain appears to be the biggest barrier to patients engaging in, and adhering to, physical activity programs. Attitudes towards the use of pain medications differ widely, and lack of efficacy or fear of side effects may lead to sub-therapeutic dosing. Furthermore, a recent review suggesting that short-term paracetamol use is ineffective for osteoarthritis has added to the confusion. This narrative review investigates limitations of current medications, summarizes patient attitudes toward the use of analgesics for osteoarthritis pain (with a focus on paracetamol), and explores the uptake of physical activity for osteoarthritis management. Evidence suggests that, despite clear guidelines, symptoms of osteoarthritis generally remain poorly managed. More research is required to investigate clinical outcomes in patients with osteoarthritis through optimized medication plans to better understand whether longer-term analgesic use in conjunction with physical activity can assist patients to overcome mobility limitations.

Abstract
Between April 2013 and April 2015, seven flocks belonging to three different major commercial egg producers inCalifornia experienced a mild increase in mortality 2 to 3 wk after administration of Salmonella Enteritidis bacterins. Strains of chickens involved were H&N (flock A1, A2, B2, C1, C2, and C3) and Lohmann white (flock B1). Vaccination was administered individually through injection either in the breast muscles or subcutis in the legs between 11 and 18 wk of age in all flocks. Clinical signs ranged from inapparent to lameness, reluctance to walk, greenish diarrhea, and retching-like symptoms. The mortality ranged from 0.16% to 1.38% per week, with the highest peaks occurring usually 2 to 3 wk postvaccination, and then declined rapidly. Postmortem examinations revealed enlarged livers with disseminated hemorrhages and pale foci of necrosis. Also, severe extensive hemorrhages in the intestine, heart, and proventriculus were observed in a few birds. Various degrees of productive, exudative giant cell granulomatous myositis were observed invading deeply the muscles and subcutis at the site of vaccination. The myositis was always associated with optically empty vacuoles positive for neutral lipids by Oil Red O stain. Droplets of Oil Red O material were also noticed in the affected livers and intestines. Congo red stain highlighted the presence of amyloid in moderate to severe amounts in the breast muscles and moderate amounts in livers, spleens, and intestines. Salmonella antigens were detected in the injection sites and livers by immunohistochemical staining. No viruses or toxic substances were recovered from the liver, spleen, intestine, and pectoral muscles, and the few bacteria isolated were interpreted as secondary postmortem invaders. In addition, livers and bile tested for hepatitis E virus were negative by reverse-transcriptase polymerase chain reaction.

Abstract
The plantar soft tissue is a highly functional viscoelastic structure involved in transferring load to the human body during walking. A Soft Tissue Response Imaging Device was developed to apply a vertical compression to the plantar soft tissue whilst measuring the mechanical response via a combined load cell and ultrasound imaging arrangement. Accuracy of motion compared to input profiles; validation of the response measured for standard materials in compression; variability of force and displacement measures for consecutive compressive cycles; and implementation in vivo with five healthy participants. Static displacement displayed average error of 0.04 mm (range of 15 mm), and static load displayed average error of 0.15 N (range of 250 N). Validation tests showed acceptable agreement compared to a Houndsfield tensometer for both displacement (CMC > 0.99 RMSE > 0.18 mm) and load (CMC > 0.95 RMSE < 4.86 N). Device motion was highly repeatable for bench-top tests (ICC = 0.99) and participant trials (CMC = 1.00). Soft tissue response was found repeatable for intra (CMC > 0.98) and inter trials (CMC > 0.70). The device has been shown to be capable of implementing complex loading patterns similar to gait, and of capturing the compressive response of the plantar soft tissue for a range of loading conditions in vivo.

Abstract
In Australia and elsewhere, chlamydia screening rates for those aged between 16 and 30 years continue to be low. Innovative, age-appropriate approaches are necessary to increase chlamydia screening among this target group to prevent short- and long-term consequences of the infection such as pelvic inflammatory disease, chronic pelvic pain, ectopic pregnancy and infertility. Studies have demonstrated that offering chlamydia screening in community pharmacies may be a useful adjunct to current screening services. Approximately 90% of Australians visit a pharmacy at least once a year. Chlamydia screening and education in community pharmacies with remuneration may provide another option for opportunistic testing as part of a national chlamydia screening scheme. Compensation is an accepted practice in the field of research and has been demonstrated to improve adherence to health promotion activities. In 2011, a cross-sectional study of community pharmacy-based chlamydia screening offered in conjunction with an A$10 cash incentive to participate was conducted in the Australian Capital Territory. As part of this study young people were asked about their experience of, and views about, pharmacy-based chlamydia screening. The views of consented participants were collected using the one-page questionnaire consisting of 10 closed questions and one open-ended question. Participants completed the questionnaire when they returned their urine sample and before being given the cash incentive. Overall participants were highly satisfied with the pharmacy-based chlamydia screening service. Over 60% of questionnaire respondents felt that the payment did affect their decision to have the chlamydia test, and 23% stated that it made no difference. Young people reported that pharmacy-based screening is acceptable and convenient. Accessibility and the small cash incentive played significant roles in increasing participation.

Abstract
BACKGROUND Internationally, the use of dietary supplements has been growing rapidly. Patient support for pharmacist sales of nutritional and dietary supplements is also strong. The increase in demand for nutritional and dietary supplements and subsequent advice about these products, however, makes it necessary that pharmacists maintain a contemporary knowledge of the area. AIM OF REVIEW This systematic review was conducted to examine the current evidence regarding the level of the nutritional and dietary supplement knowledge of community pharmacists and their understanding of their therapeutic effects. METHOD Electronic databases including Medline, Scopus, Embase, CINAHL, Scifinder and the Cochrane Controlled Trials Register were searched. Studies assessing nutritional knowledge of pharmacists in community pharmacies were eligible for inclusion. All languages and study designs were considered. Study results were analysed and pharmacist knowledge scores were given out of 100 %. Results From 5594 studies identified, nine met the inclusion criteria. Each study tested pharmacist knowledge with predetermined questions calculating results as the number of questions answered correctly. These knowledge scores were converted to a percentage score for the purpose of this paper. The median knowledge score across all papers was 64 %. A lack of studies assessing community pharmacists' knowledge of commonly sold vitamins and minerals was observed. CONCLUSIONS Global community pharmacist knowledge of dietary supplements appears to be poor. Community pharmacists have an professional responsibility to provide accurate health information about dietary supplements as they do for any other therapies they provide to patients. Further research including that which assesses pharmacists' therapeutic knowledge of commonly sold vitamins and minerals is suggested.

INTRODUCTION Trauma remains the highest cause of paediatric morbidity and mortality. These trauma patients incur radiation exposure during intraoperative management. Medical personnel have the responsibility to ensure observation of the 'as low as reasonably achievable' principle, a practice mandate that minimises ionising radiation exposure. The aim of this study was to quantify the difference in the amount of ionising radiation used by operating surgeons of different grades in paediatric trauma surgery. METHODS Intraoperative imaging in paediatric trauma surgery between 2008 and 2010 at a UK trauma centre was analysed retrospectively, recording injury demographics, surgeon grade, radiation exposure (dose area product [DAP]) and screening time. A mobile image intensifier was used in all cases and the lowest dose rate was selected for all screening. RESULTS A total of 782 trauma cases were analysed: 304 procedures (39%) were carried out by consultants, 127 (16%) by senior registrars and 351 (45%) by junior registrars. The mean screening time for consultants was 0.23 minutes (standard deviation [SD]: 0.21 minutes) while for senior registrars it was 0.24 minutes (SD: 0.27 minutes) and for junior registrars 0.47 minutes (SD: 1.5 minutes). The mean DAP for consultants was 58.49Gycm(2) (SD: 53.66Gycm(2)). For senior registrars it was 87.2Gycm(2) (SD: 126.64Gycm(2)) and for junior registrars it was 90.46Gycm(2) (SD: 180.02Gycm(2)). This equates to a 51% increase in screening time and a 35% increase in DAP by a junior registrar compared with a consultant. CONCLUSIONS Significantly lower screening times and radiation exposure was found in procedures performed by consultants compared with registrars (p<0.001). Given the harmful and unknown long-term effects of ionising radiation exposure in children, we recommend increasing consultant presence in paediatric trauma theatres.

Abstract
INTRODUCTION Limited human resources are a major impediment to achieving the UN health-related Millennium Development Goals in a number of Pacific Island Countries (PICs). Lack of education capacity to support competency development in medicine supply management is one of the main issues affecting workforce development in this region, which is characterised by disparate service delivery due to the range of environments in which supply occurs (ie urban, rural and remote), geographical challenges and cultural practices associated with teaching and learning. The supply of medicines, and an adequate pharmacy workforce with appropriate competencies is crucial to ensuring a well-functioning pharmaceutical system. In this region approximately 80% of patients access healthcare in rural areas without a pharmacist, thus local health personnel must be competent in pharmaceutical management relevant to the local context and culture. A new approach involves a partnership between the UN Population Fund Suva Sub-Regional Office, University of Canberra, Ministry of Health officials and the heath personnel within identified PICs, starting with the need to understand local culture and its impact on learning and teaching, and the mapping of competency requirements and an understanding of currently available information and materials. This information will be used to develop and trial new pedagogical approaches to training health personnel involved in essential medicines supply management, to improve medicines availability for patients in their own environment. The focus of this review was to determine what cultural and learning factors need to be considered when developing a curriculum for South Pacific pharmaceutical health personnel who work across a range of practice environments. METHODS A 'realist methodology' consisting of a systematic investigation of the published literature and a targeted review of the 'grey' literature was used. All relevant literature was retrieved and coded manually using broad thematic analysis. RESULTS The combined bibliographic and 'grey' literature search strategy resulted in the inclusion of 17 full text articles, 44 documents and 10 books. The five themes identified as key to optimising the cultural and learning approaches for the study population included recognition of: (1) past regional experiences of health related training; (2) the impact of South Pacific culture on learning styles; (3) the impact of external influences on curriculum; (4) the challenges of open and distance education in the Pacific; and (5) a distinct South Pacific student learning approach. CONCLUSIONS The results of this 'realist methodology' review provide insights into learning approaches and cultural influences on student learning within PICs. The themes generated will be used to develop a set of principles to inform educators and health personnel involved in pharmaceutical training within PICs.

Abstract
Advances in the operationalization of psychopathy have led to an increased understanding of the boundaries, structure, and nomological network of this construct, although significant questions remain. The empirical identification of replicable and theoretically meaningful psychopathy subtypes may help to improve the classification and diagnosis of this condition. We conducted a classification study of 91 incarcerated men who met conventional criteria for high levels of psychopathy using the Psychopathy Checklist-Revised. We expanded on the methodology of previous research on psychopathy subtypes by utilizing a comprehensive personality assessment instrument and a prototype matching approach to classification. The analyses revealed a primary (narcissistic) subtype and a secondary (hostile and dysregulated) subtype that were broadly consistent with the previous literature. External validation analyses, statistical controls, and incremental validity analyses provided substantial support for the primary and secondary subtypes.

Abstract
Blast injuries are an increasing problem in both military and civilian practice. Primary blast injury to the lungs (blast lung) is found in a clinically significant proportion of casualties from explosions even in an open environment, and in a high proportion of severely injured casualties following explosions in confined spaces. Blast casualties also commonly suffer secondary and tertiary blast injuries resulting in significant blood loss. The presence of hypoxaemia owing to blast lung complicates the process of fluid resuscitation. Consequently, prolonged hypotensive resuscitation was found to be incompatible with survival after combined blast lung and haemorrhage. This article describes studies addressing new forward resuscitation strategies involving a hybrid blood pressure profile (initially hypotensive followed later by normotensive resuscitation) and the use of supplemental oxygen to increase survival and reduce physiological deterioration during prolonged resuscitation. Surprisingly, hypertonic saline dextran was found to be inferior to normal saline after combined blast injury and haemorrhage. New strategies have therefore been developed to address the needs of blast-injured casualties and are likely to be particularly useful under circumstances of enforced delayed evacuation to surgical care.

Abstract
Abstract
A study was carried out to examine the dosing of gentamicin and to investigate some of the determinants of serum gentamicin concentrations in neonates at the Royal Hobart hospital, Tasmania, Australia, and to examine the appropriateness of the current dosing protocol (that of the Royal Children's hospital, Melbourne). Clinical and demographic data were retrospectively collected from the records of 39 neonates who had received therapy with gentamicin for suspected or proven septicaemia during the period May to September, 1993. Peak and trough serum concentrations of gentamicin were measured, at least 36 hours after starting therapy. The mean gestational age (± SD) of the sample was 32.3 ± 4.9 weeks, and 30 patients were male. The mean dosage of gentamicin was 4.0 ± 1.3mg/kg/day and the median duration of therapy was 4 days (range 2 to 22 days). Trough serum concentrations of gentamicin ranged from 0.6 to 6.0mg/L (mean 1.9 ± 1.0mg/L), with 35.9 per cent being 2.0mg/L or higher. Peak serum concentrations ranged from 4.3 to 12.9 mg/L (mean 6.1 ± 1.5 mg/L), with 89.7 per cent being between 5.0 and 8.0mg/L. The peak and trough serum concentrations were significantly related, while the total daily dosage of gentamicin and the resulting peak and trough serum concentrations were not significantly related. The trough serum concentration of gentamicin was significantly related to the serum creatinine concentration. Patients who had been dosed correctly according to the protocol were less likely to have a potentially toxic trough serum concentration of gentamicin. Those administered gentamicin every 12 hours tended to have higher serum trough concentrations of the drug than those who received it either 18- or 24-hourly.
This study has confirmed that excessive serum concentrations of gentamicin occur frequently in neonates, a situation which may be improved by greater usage of an 18-hourly dosing regimen and prompt adjustment of dosage according to renal function.

Abstract
Objective To describe the patterns and clinical features of toxicity related to recreational use of mephedrone and other cathinones in the UK using data collected by the National Poisons Information Service (NPIS). Methods The number of accesses to TOXBASE, the NPIS online poisons information database, details of consecutive cases uploaded onto TOXBASE and the number and details of telephone enquiries made to the NPIS by health professionals in the UK were collected for the period March 2009 to February 2010. Results Over the year of study there were 2901 TOXBASE accesses and 188 telephone enquiries relating to cathinones, the majority relating to mephedrone (TOXBASE 1664, telephone 157), with a month-on-month increase in numbers. In 131 telephone enquiries concerning mephedrone, alone or in combination with alcohol, common clinical features reported included agitation or aggression (n=32, 24%, 95% CI 18% to 33%), tachycardia (n=29, 22%, 95% CI 16% to 30%), confusion or psychosis (n=18, 14%, 95% CI 9% to 21%), chest pain (n=17, 13%, 95% CI 8% to 20%), nausea (n=15, 11%, 95% CI 7% to 18%), palpitations (n=14, 11%, 95% CI 6% to 18%), peripheral vasoconstriction (n=10, 8%, 95% CI 4% to 14%) and headache (n=7, 5%, 95% CI 2% to 11%). Convulsions were reported in four cases (3%, 95% CI 1% to 8%). One exposed person died following cardiac arrest (1%, 95% CI 0% to 4%), although subsequent investigation suggested that mephedrone was not responsible. Conclusions Toxicity associated with recreational mephedrone use is increasingly common in the UK. Sympathomimetic adverse effects are common and severe effects are also reported. Structured data collected by the NPIS may be of use in identifying trends in poisoning and in establishing toxidromes for new drugs of abuse.

Comparative study of the valence electronic excitations of N2 by inelastic x-ray and electron scattering. PHYSICAL REVIEW LETTERS 2010; 105:053202.

Abstract
Bound-state, valence electronic excitation spectra of N2 are probed by nonresonant inelastic x-ray and electron scattering. Within usual theoretical treatments, dynamical structure factors derived from the two probes should be identical. However, we find strong disagreements outside the dipole scattering limit, even at high probe energies. This suggests an unexpectedly important contribution from intramolecular multiple scattering of the probe electron from core electrons or the nucleus. These effects should grow progressively stronger as the atomic number of the target species increases.

Abstract
The unclassified strains known as Group IV have been separated into twenty-nine types which are designated by the Roman numerals IV and XXXII. Only a small percentage of the pneumococcus strains isolated in New York City for this study were left unclassified. The majority of the types gave very slight cross-reactions, the exceptions being Types II and V, III and VIII, VII and XVIII and XV and XXX. In the series of cases studied, Types IV, V, VII and VIII were found more prevalent in the lobar pneumonia of adults and Types V, VI a and XIV in children. The majority of the types were also found in normal individuals and in persons having respiratory infections other than pneumonia. Types VI a and XIX were most prevalent in the limited number of strains studied by us. Fourteen of the types were found in pneumococcus meningitis; Type XVIII was found most often. Antisera suitable for clinical trial have been prepared for fourteen types. From the majority of the horses inoculated for more than a year, antisera having 500 to 1000 units per cc. were obtained. Antisera of lower potency were concentrated and preparations obtained equal to or stronger than high grade unconcentrated serum. Potent bivalent antisera have been prepared for types which were found to give marked cross-agglutination reactions. The results with each type as to prevalence, severity of cases, presence in normal individuals, and in spinal meningitis, potency of antisera produced for therapeutic trial and virulence of strains for mice have been considered under the different type headings.
