Outbreaks of Pseudomonas aeruginosa infections have been linked to water-related sources. We describe the investigation of a suspected outbreak of five P. aeruginosa infections in pediatric oncology patients in 2021 that triggered a retrospective review and prospective monitoring of additional cases, environmental sampling, and bacterial genomic analysis.
Setting and patients:
Pediatric oncology center.
Methods:
Medical records of patients with P. aeruginosa were reviewed and staff were interviewed to identify common exposures. Environmental samples were cultured for P. aeruginosa. Patient and environmental isolates underwent whole genome sequencing and core genome multi-locus sequence typing (cgMLST) and sequences were added to a previously existing library of P. aeruginosa clinical isolates collected in 2017 and onwards to determine strain relatedness.
Findings:
During 2019–2022, 82 patients with 110 episodes of P. aeruginosa infections were identified and 132 isolates of P. aeruginosa were sequenced. Twenty-three environmental samples were collected, of which two grew P. aeruginosa in culture. CgMLST demonstrated four multi-patient isolate clusters but no genetic relatedness among the isolates from the patients in the suspected outbreak. Two sink-derived isolates from 2021 were genetically related to patient-derived isolates from 2018 and 2017.
Conclusions:
Sequencing revealed there is no common source or linkage between the isolates of the suspected P. aeruginosa outbreak in 2021. However, it revealed genetic relatedness of previous patient strains to later strains collected from hospital sinks, suggesting persistent colonization of a reservoir with P. aeruginosa.
Health benefits represent employers’ fastest growing operating expense. Efforts from human resources to control healthcare spending through restrictive plan design changes and corporate wellness programs may not achieve employer health and financial goals and may negatively impact employee outcomes. Employers are increasingly contracting directly with providers in order to access quality medical care and to control spending. The purpose of this practice-focused paper is to provide survey data collected from 10 employers as part of the quality improvement activities of a direct primary care (DPC) program. Overall, survey responses of employees engaged with DPC had higher patient satisfaction, group health plan rating, perceived organizational support, and job satisfaction than survey responses of those registered into the program but not yet engaged with a DPC physician. Implementation considerations and DPC characteristics are provided.
Although first identified 120 years ago, knowledge of the Toalean technoculture of Middle Holocene Sulawesi, Indonesia, remains limited. Previous research has emphasised the exploitation of largely terrestrial resources by hunter-gatherers on the island. The recent recovery of two modified tiger shark teeth from the Maros-Pangkep karsts of South Sulawesi, however, offers new insights. The authors combine use-wear and residue analyses with ethnographic and experimental data to indicate the use of these artefacts as hafted blades within conflict and ritual contexts, revealing hitherto undocumented technological and social practices among Toalean hunter-gatherers. The results suggest these artefacts constitute some of the earliest archaeological evidence for the use of shark teeth in composite weapons.
Systemic lupus erythematosus in children generally manifests more severely with a more aggressive disease course. Cardiac involvement in systemic lupus erythematosus often does not show specific signs and symptoms, but speckle-tracking echocardiography can detect cardiac dysfunction. This study aimed to determine the differences in left ventricular function as measured by speckle-tracking echocardiography in children with various severity of systemic lupus erythematosus activity.
Methods:
A cross-sectional study of 49 children diagnosed with systemic lupus erythematosus are currently undergoing outpatient or inpatient care at Dr Hasan Sadikin General Hospital, Bandung, from May 2023 to June 2023. Disease activity was assessed by Mexican Version of the Systemic Lupus Erythematosus Disease Activity Index (MEX-SLEDAI) with a score of 2–5 classified as mild activity, 6–9 as moderate, and ≥10 as severe. Each subject underwent conventional echocardiography and speckle-tracking echocardiography with a Philips EPIQ machine performed by a Pediatric Cardiologist Consultant 10 days after inclusion.
Results:
Fifteen (30.6%) subjects had mild disease activity, and 34 (69.4%) subjects had moderate disease activity. Most subjects (81.96%) were female with an average age of 15 years. The mean ejection fraction and fractional shortening as well as the median E/A ratio in the mild and moderate disease activity groups were not significantly different (65.76 versus 67.38%, 35.73 versus 37.11%, 1.6 versus 1.5%, respectively, p > 0.005). The global longitudinal strain in the moderate activity group was reduced more significantly than in the mild activity group (−16.58 versus −19.65, p = 0.008).
Conclusion:
Left ventricular function as measured by speckle-tracking echocardiography was lower in children with moderate systemic lupus erythematosus activity than those with mild disease activity.
Four decades of war, political upheaval, economic deprivation and forced displacement have profoundly affected both in-country and refugee Afghan populations.
Aims
We reviewed literature on mental health and psychosocial well-being, to assess the current evidence and describe mental healthcare systems, including government programmes and community-based interventions.
Method
In 2022, we conducted a systematic search in Google Scholar, PTSDpubs, PubMed and PsycINFO, and a hand search of grey literature (N = 214 papers). We identified the main factors driving the epidemiology of mental health problems, culturally salient understandings of psychological distress, coping strategies and help-seeking behaviours, and interventions for mental health and psychosocial support.
Results
Mental health problems and psychological distress show higher risks for women, ethnic minorities, people with disabilities and youth. Issues of suicidality and drug use are emerging problems that are understudied. Afghans use specific vocabulary to convey psychological distress, drawing on culturally relevant concepts of body–mind relationships. Coping strategies are largely embedded in one's faith and family. Over the past two decades, concerted efforts were made to integrate mental health into the nation's healthcare system, train cadres of psychosocial counsellors, and develop community-based psychosocial initiatives with the help of non-governmental organisations. A small but growing body of research is emerging around psychological interventions adapted to Afghan contexts and culture.
Conclusions
We make four recommendations to promote health equity and sustainable systems of care. Interventions must build cultural relevance, invest in community-based psychosocial support and evidence-based psychological interventions, maintain core mental health services at logical points of access and foster integrated systems of care.
In big companies, Circular Economy (CE) is being explored, nevertheless, Small and Medium-sized Enterprises (SMEs) struggle to follow because of particular barriers and a lack of practical guide. Here, we use Style & Design, a French industrial SME, as a case study to explore how SMEs can perform a successful CE integration. This article aims at proposing a multi-internal actor circularity diagnosis method. It focuses on building an inclusive and co-constructed therefore well-accepted and persistent integration of CE for SMEs, which is lacking today in the existing literature. This work relies on a mixed qualitative and quantitative data analysis applied on a corpus of 42 one-hour-long semi-structured interviews, with 37 different professions. We capture the view of the current and desired situation and identify CE barriers unique to each interviewed worker. We also connect with each worker and open the dialog for the rest of the CE deployment. The final goal is to assemble this worker-oriented diagnosis with quantitative diagnosis, like Life Cycle Analysis of the products and Material Flow Analysis of the factory, to diagnose a complete picture of an industrial SME circularity.
Prosocial behavior plays a crucial role in the social success of children and adolescents. This chapter reviews research on the relations between prosocial behavior and features of youth’s relationships with peers, both within groups and dyadically within friendships. We also discuss possible theoretical mechanisms that may link prosocial behavior to functioning with peers, highlighting lingering questions and future directions to guide research in this area.
Continental silicate weathering and seafloor carbonate precipitation are key steps in the carbonate-silicate cycle to draw down CO2. Contrary to the classic understanding of negative feedback, silicate weathering can exhibit positive feedback at high temperatures. Taking into account this positive feedback, the compensation depth (CCD) in exoplanet oceans becomes shallower, implying a potential instability in the carbonate-silicate cycle at high temperatures.
Labeled graphs are particularly well adapted to represent objects in the context of topology-based geometric modeling. Thus, graph transformation theory is used to implement modeling operations and check their consistency. This article defines a class of graph transformation rules dedicated to embedding computations. Objects are here defined as a particular subclass of labeled graphs in which arc labels encode their topological structure (i.e., cell subdivision: vertex, edge, face) and node labels encode their embedding (i.e., relevant data: vertex positions, face colors, volume density). Object consistency is defined by labeling constraints which must be preserved by modeling operations that modify topology and/or embedding. Dedicated graph transformation variables allow us to access the existing embedding from the underlying topological structure (e.g., collecting all the points of a face) in order to compute the new embedding using user-provided functions (e.g., compute the barycenter of several points). To ensure the safety of the defined operations, we provide syntactic conditions on rules that preserve the object consistency constraints.
In Indonesia, as in other countries, a large proportion of tax returns are filed at the last minute. In a population-wide randomised controlled trial (n = 11,157,069), we evaluated the impact of behavioural email prompts on the proportion of annual tax returns filed at least two weeks before the deadline; and overall filing rate. In two control conditions, taxpayers either received no email or an email used in prior years, emphasising regulatory information. The five treatments informed by behavioural science were (1) a simplified version of the existing email, emphasising early filing; (2) the simplified version with additional guidance on filing taxes; (3) the simplified version with a planning prompt and option to sign up for email reminders; (4) a version combining treatments 1, 2 and 3; and (5) an email appealing to national pride. Compared to the no-email control, all emails led to a statistically significant increase in early and overall filing rates. The planning email (3) was the most effective, increasing early filling from 34.9% to 37% (b 2.07 percentage points (pp), p < 0.001, 95% confidence interval (CI) 1.97–2.17pp), and overall filing from 65.6% to 66.7% (b 1.10pp, p < 0.001, 95% CI 0.99–1.19pp).
This special communication provides an approach for applying implementation science frameworks to a Clinical and Translational Science Institutes (CTSIs) community engagement (CE) program that measures the use of implementation strategies and outcomes that promote the uptake of CE in research. Using an iterative multi-disciplinary group process, we executed a four-phased approach to developing an evaluation plan: 1) creating an evaluation model adapted from Proctor’s conceptual model of implementation research; 2) mapping implementation strategies to CTSI CE program interventions that support change in research practice; 3) identifying and operationalizing measures for each strategy; and 4) conducting an evaluation. Phase 2 employed 73 implementation strategies across 9 domains generated by the Expert Recommendations for Implementing Change project. The nine domains were used to classify each CE program implementation strategy. In Phase 3, the group used the Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) framework to define measures for each individual strategy. Phase 4 demonstrates the application of this framework and measures Year 1 outcomes for the strategy providing interactive assistance, which we implemented using a centralized consultation model. This approach can support the CTSA program in operationalizing CE program measurement to demonstrate which activities and strategies may lead to benefits derived by the program, institution, and community.
To improve the information exchange between oncall junior doctors and ward teams between shifts including outstanding tasks, alerts and prompts to update clinical record systems accordingly (Rio). We aimed for the handover to be circulated to the correct recipients in 95% of cases as well as to improve its content. This would minimise loss of information and improve patient safety.
Methods
Handover document set up on MS Teams which is accessed by oncall junior doctors and day teams and can be updated live. Relevant training was offered to trainees during induction. We measured the number of days the document is updated and distributed and also measured the tasks not completed or not documented. We measured doctors' satisfaction via a survey.
Results
We found that on average the handover document is updated and circulated correctly at a rate of 94.8% since the new MS Teams system was implemented. Participating doctors' survey showed that they felt that this system is safe and easy to use as well as reliable and more efficient than the previous system. They also noted that the training they received during induction was helpful and sufficient.
Conclusion
The digitalisation of the handover process using MS Teams, developed and improved through various PDSA cycles, has resulted in a system which the users find efficient, safe and easy to use. This leads to minimisation of information losses and improves patients' safety.
The Dougherty model Fokker–Planck operator is extended to describe nonlinear full-$f$ ( f is the distribution function) collisions between multiple species in plasmas. Simple relations for cross-species primitive moments are developed which obey conservation laws, and reproduce familiar velocity and temperature relaxation rates. This treatment of multispecies Dougherty collisions, valid for arbitrary mass ratios, avoids unphysical temperatures and satisfies the $H$-theorem (H is related to the entropy) unlike an analogous Bhatnagar–Gross–Krook operator. Formulas for both a Cartesian velocity space and a gyroaveraged operator are provided for use in Vlasov as well as long-wavelength gyrokinetic models. We present an algorithm for the discontinuous Galerkin discretization of this operator, and provide results from relaxation and Landau damping benchmarks.
We describe a cluster of 6 pediatric hematopoietic cell transplant recipients with Lactobacillus bacteremia attributed to probiotic use. Lactobacillus isolates cultured from probiotics and patients’ blood were proven to be related using whole-genome sequencing. Clinical studies are needed to evaluate the safety of probiotic use in immunocompromised patients.
With unprecedented times, comes accelerated change. Hospitals in our region have begun to facilitate safe discharge for COVID-19 patients in the form of “The virtual COVID ward”. This has enabled patients to be monitored safely in the community using pulse oximetry, Florence (a telehealth mobile app) and remote consultations. Our objective is to expand upon this model by providing home oxygen therapy for these patients facilitated by telemedicine.
Methods
Patients were discharged with an oxygen concentrator if they had an oxygen requirement equal to or less than four litres/minute. Fraction of inspired oxygen needed to be stable and an early warning score of less than four was also required. Once admitted, the Florence app and daily remote consultations were crucial to closely monitor the patient's clinical status. The patient was instructed to enter oxygen saturations and heart rate into the app four times daily. The app would then alert our team if any patients observations deteriorate, triggering immediate assessment.
Results
We have discharged ninety patients to the virtual ward, fifty-six of these with home oxygen. The average age was fifty-seven and the Clinical Frailty Score ranged between one and six. At present, ten patients have been re-admitted, four with increasing oxygen requirements, and six with unrelated symptoms. Two patients had oxygen concentrators installed at home after we were alerted to their desaturation by the Florence App. The re-admission rate is eleven percent, which mirrors that of other virtual wards (who do not provide home oxygen). In total, the ward has saved the trust 627 hospital inpatient ‘days’. Patients report increased satisfaction at playing a meaningful role in monitoring their own healthcare using the app.
Conclusions
Our novel model of supported discharge with oxygen therapy using telehealth demonstrates that it is possible to manage such patients, safely, in the community. Other trusts could utilise this model to reduce inpatient bed occupancy. Looking to the future, could telehealth be utilised further to facilitate other “Virtual wards” in the community?
Upwardly buoyant air parcels can produce powerful thunderstorms, towering cumulonimbus clouds producing rain, hail, lightning, and thunder. When these thunderstorms rotate, they can also spawn tornadoes and cause some of the most severe weather on Earth. We will now describe the different stages of thunderstorm development, the formation of lightning and thunder, and will explain the circumstances and mechanism by which tornadoes can form at the base of a supercell thunderstorm.
How will weather change as our planet warms and our climate changes? Will there be more droughts? How will precipitation patterns be affected? Will there be more or fewer storms? Will tropical cyclones be more, or less, intense? Will all regions of the world be affected? In this last chapter, we will put in perspective all that we have learned about the atmosphere and apply it to the pressing issue of global warming.
