Ghost: A General Framework for High-Performance Online Similarity Queries over Distributed Trajectory Streams
Authors: Fang Ziquan , Gong Shenghao , Chen Lu , Xu Jiachen , Gao Yunjun , Jensen Christian S. 
Published: June 2023

Trajectory similarity queries, including similarity search and similarity join, offer a foundation for many geo-spatial applications. With the rapid increase of streaming trajectory data volumes, e.g., data from mobile phones, vessel monitoring, or traffic systems, many location-based services benefit from online similarity analytics over trajectory data streams, where moving objects continually emit real-time position data. However, most existing studies focus on offline settings, and thus several major challenges remain unanswered in an online setting. To this end, we describe Ghost, a distributed stream processing framework that enables generic, efficient, and scalable online trajectory similarity search and join.
We propose a novel incremental online similarity computation (IOSC) mechanism to accelerate pair-wise streaming trajectory distance calculation, which supports a broad range of trajectory distance metrics. Compared with previous studies, IOSC reduces the complexity from quadratic to linear in terms of trajectory length. Building on this foundation, we propose histogram-based algorithms that exploit histogram indexes and a series of pruning bounds to enable streaming trajectory similarity search and join. Finally, we extend our methods to the distributed platform Flink for scalability, where a CostPartitioner is developed to ensure parallel processing and workload balancing. An experimental study using two real-life and one synthetic datasets shows that Ghost (i) acquires 6-20× efficiency/throughput gains and one order of magnitude memory overhead savings over state-of-the-art baselines, (ii) achieves 3--8× workload balancing gains on Flink, and (iii) exhibits low parameter sensitivity and high robustness.
LAQy: Efficient and Reusable Query Approximations via Lazy Sampling
Authors: Sanca Viktor , Chrysogelos Periklis , Ailamaki Anastasia 
Published: June 2023

Modern analytical engines rely on Approximate Query Processing (AQP) to provide faster response times than the hardware allows for exact query answering. However, existing AQP methods impose steep performance penalties as workload unpredictability increases. Specifically, offline AQP relies on predictable workloads to create samples that match the queries in a priori to query execution, reducing query response times when queries match the expected workload. As soon as workload predictability diminishes, existing online AQP methods create query-specific samples with little reuse across queries, producing significantly smaller gains in response times. As a result, existing approaches cannot fully exploit the benefits of sampling under increased unpredictability.
We analyze sample creation and propose LAQy, a framework for building, expanding, and merging samples to adapt to the changes in workload predicates. We show the main parameters that affect the sample creation time and propose lazy sampling to overcome the unpredictability issues that cause fast-but-specialized samples to be query-specific. We evaluate LAQy by implementing it in an in-memory code-generation-based scale-up analytical engine to show the adaptivity and practicality of our framework in a modern system. LAQy speeds up online sampling processing as a function of sample reuse ranging from practically zero to full online sampling time and from 2.5x to 19.3x in a simulated exploratory workload.
Mitigating Filter Bubbles Under a Competitive Diffusion Model
Authors: Banerjee Prithu , Chen Wei , Lakshmanan Laks V.S. 
Published: June 2023

While social networks greatly facilitate information dissemination, they are well known to have contributed to the phenomena of filter bubbles and echo chambers. This in turn can lead to societal polarization and erosion of trust in public institutions. Mitigating filter bubbles is an urgent open problem. Recently, approaches based on the influence maximization paradigm have been proposed in our community for mitigating filter bubbles by balancing exposure to opposing viewpoints. However, existing works ignore the inherent competition between the adoption of opposing viewpoints by users.
In this paper, we propose a realistic model for the filter bubble problem, which unlike previous work, captures thecompetition between opposing opinions propagating in a network as well as thecomplementary nature of the reward forexposing users to both those opinions. We formulate an optimization problem for mitigating filter bubbles under our model. We establish several evidences of the intrinsic difficulty in developing constant approximation to the problem and develop a heuristic and two instance-dependent approximation algorithms. Our experiments over 4 real datasets show that our heuristic far outperforms two state-of-the-art baselines as well as other algorithms in both efficiency and mitigating filter bubbles. We also empirically demonstrate that our best heuristic performs close to the optimal objective, which is obtained by utilizing the theoretical bounds of our approximation algorithms.
Medicaid Expansion Under the Affordable Care Act and Association With Cardiac Care: A Systematic Review
Authors: Jiang Ginger Y. , Urwin John W. , Wasfy Jason H. 
Published: June 2023

Background:
The goal of the Affordable Care Act was to improve health outcomes through expanding insurance, including through Medicaid expansion. We systematically reviewed the available literature on the association of Affordable Care Act Medicaid expansion with cardiac outcomes.

Methods:
Consistent with Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines, we performed systematic searches in PubMed, the Cochrane Library, and Cumulative Index to Nursing and Allied Health Literature using the keywords such as Medicaid expansion and cardiac, cardiovascular, or heart to identify titles published from 1/2014 to 7/2022 that evaluated the association between Medicaid expansion and cardiac outcomes.

Results:
A total of 30 studies met inclusion and exclusion criteria. Of these, 14 studies (47%) used a difference-in-difference study design and 10 (33%) used a multiple time series design. The median number of postexpansion years evaluated was 2 (range, 0.5–6) and the median number of expansion states included was 23 (range, 1–33). Commonly assessed outcomes included insurance coverage of and utilization of cardiac treatments (25.0%), morbidity/mortality (19.6%), disparities in care (14.3%), and preventive care (41.1%). Medicaid expansion was generally associated with increased insurance coverage, reduction in overall cardiac morbidity/mortality outside of acute care settings, and some increase in screening for and treatment of cardiac comorbidities.

Conclusions:
Current literature demonstrates that Medicaid expansion was generally associated with increased insurance coverage of cardiac treatments, improvement in cardiac outcomes outside of acute care settings, and some improvements in cardiac-focused prevention and screening. Conclusions are limited because quasi-experimental comparisons of expansion and nonexpansion states cannot account for unmeasured state-level confounders.
Abstract Labour and Socialism
Authors: Khosravi Kamal 
Published: June 2023

Abstract
Should the regulation of production and distribution in a socialist society be based on the law of value? In this article we ask (1) Is this question not based on an ontological understanding of labour, on a rational and therefore conceptual understanding of abstract labour and, ultimately, a transhistorical understanding of value and the so-called ‘law of value’?; (2) is it not precisely this deception and power of the fetishism of commodities that, by eternalising value and the ‘law of value’, limits the horizon and perspective of ‘realistic politics’ (Realpolitik)?; and (3) whether this question does not treat socialism as a political situation where the solution to its ‘economic’ problem is unrelated to its very identity? In order to answer these questions, we provide a novel understanding of Marx’s fundamental category of value, its substance, form and magnitude, with the help of the German expression Formgehalt, translated as form-content.
„Reinhart Fuchs“ und der Arzt aus Salerno
Authors: Schneidergruber Dietmar 
Published: June 2023

Abstract
The article deals with the interpretation and dating of the „Märe“ Reinhart Fuchs, with its political function being elaborated. This is accomplished by means of a hierarchical order of the animal protagonists in a society of estates. The author of Reinhart Fuchs establishes a context with the „Märe“ Der arme Heinrich and draws on the new medical developments from Salerno, but also uses his own medical knowledge. Thereby, King Vrevel is characterised as a selfish person who, as a ruler, has no Christian virtue. The „Märe“ is defined by its anti-Staufian character and can thus also be classified quite accurately in terms of time. The author can be assumed to be Heinrich von Avranches, who had the requirements and the necessary knowledge.
Artificially raised creatinine concentrations due to analytical interference for samples contaminated with total parenteral nutrition fluid
Authors: Jeffery Jinny , Millar Helen , Marrington Rachel , MacKenzie Finlay , George Roanna 
Published: June 2023

Background A sample received in the laboratory from a patient receiving total parenteral nutrition (TPN) indicated that the patient may have renal dysfunction, but the results were not considered to be reliable enough to report. Investigations using a reference method for measurement of creatinine confirmed positive interference in the creatinine assay and distribution of samples via an External Quality Assessment (EQA) Scheme showed that this positive interference was method dependent. Methods Residual TPN fluid (Nutriflex Lipid Special) left in the bag after the patient had completed the infusion was collected and added to a patient serum pool in increasing amounts and distributed to different laboratories for analysis of creatinine and glucose through an EQA Scheme. Results Positive interference in a number of different creatinine assays was identified as a result of a component in the TPN fluid. Positive interference from high concentrations of glucose has been demonstrated to be a cause for falsely high results in Jaffe creatinine assays. Conclusions The concern would be that a sample contaminated with TPN fluid would have both abnormal electrolytes and creatinine concentrations and give the impression that the patient was in renal failure due to analytical interference in the creatinine assay and laboratory staff need to be aware of this problem.
Experimental and numerical investigations on the mode I delamination growth behavior of reinforced laminates via a ZPI (Z-pin pre-hole insertion) technique
Authors: Liu Weiwei , Jin Kexin , Cheng JiSiyuan , Yan Bin , Yin Mingxin , Sang Chen 
Published: June 2023

This paper proposes a low-in-plane damage ZPI (Z-pin pre-hole insertion) process. The delamination growth behavior and the influence of Z-pin insertion density on the mode I interlaminar fracture toughness of laminate was explored experimentally and numerically. Meanwhile, Z-pin pull-out and shear tests were conducted in order to provide accurate data for the DCB simulation test. What’s more, an infinite-focus microscope was used to scan the specimen’s defect caused by the ZPI process. It can be found that the ZPI process can lead to less Z-pin inclination, fibre breaking, and crack initiation at the bonded interface. The DCB test results show that the load-displacement curve can be distinguished into four stages for the pinned specimen. In addition, a specimen pinned with a higher Z-pin volume fraction to more suitable for increasing the G IC. The simulation results show that the simulated maximum load and the G IC of the specimen are 286.63 N and 940.06 J·m−2, with a 0.56% and 10.10% error from the experimental result, indicating that the proposed FE model is validated by comparing the predictions with the experimental results. These results can provide some guidance for fabricating the reinforced laminates via the ZPI process.
Application of indocyanine green lymphography combined with methylene blue staining in lymphaticovenular anastomosis of lower limb vessels: A prospective study
Authors: Zhou Xuchuan , Liu Bin , Guo Xiaowei , Tang Yueling , Ma Gejia 
Published: June 2023

Background Methylene blue (MB) is a conventional lymphatic tracer. We evaluated the application of indocyanine green (ICG) lymphography combined with MB staining in lower limb lymphaticovenular anastomosis (LVA). Methods A total of 49 patients with lower limb lymphedema were selected as the study subjects and divided into the research ( n = 27) and control groups ( n = 22). The patients were treated with LVA using ICG lymphography combined with MB staining and simple ICG lymphography as the positioning method, respectively. The number of lymphatic vessels anastomosed and the operating time were compared between the groups. Lower Extremity Lymphedema Index (LEL index) and Lymphoedema Functioning, Disability and Health Questionnaire for Lower Limb Lymphoedema (Lymph-ICF-LL) were used as prognostic indices; 6 months after LVA, both groups were evaluated for the symptomatic relief of lymphedema. Results The number of anastomotic lymphatic vessels in the study group was higher than that in the control group ( p < .05), and their procedural time was shorter than that in the control group. The two groups had no significant difference in lymphatic anastomosis time ( p > .05). The LEL index and Lymph-ICF-LL of the research and control groups at 6-month follow-up after LVA were lower than those before the operation ( p < .05). Conclusion The circumference of the affected limb is reduced after LVA in patients with lower extremity lymphedema with a favorable prognosis. ICG lymphography combined with MB staining has the advantages of real-time visualization and accurate localization.
Current Practice Patterns, Challenges, and Need for Education in Performing and Reporting Advanced Pelvic US and MRI to Investigate Endometriosis: A Survey by the Canadian Association of Radiologists Endometriosis Working Group

Published: June 2023

Purpose: The Canadian Association of Radiologists (CAR) Endometriosis Working Group developed a national survey to evaluate current practice patterns associated with imaging endometriosis using advanced pelvic ultrasound and MRI to inform forthcoming clinical practice guidelines for endometriosis imaging. Methods: The anonymous survey consisted of 36 questions and was distributed electronically to CAR members. The survey contained a mix of multiple choice, Likert scale and open-ended questions intended to collect information about training and certification, current practices and protocols associated with imaging endometriosis, opportunities for quality improvement and continuing professional development. Descriptive statistics were used to summarize the results. Results: Canadian radiologists were surveyed about their experience with imaging endometriosis. A total of 89 responses were obtained, mostly from Ontario and Quebec. Most respondents were community radiologists, and almost 33% were in their first five years of practice. Approximately 38% of respondents reported that they or their institution performed advanced pelvic ultrasound for endometriosis, with most having done so for less than 5 years, and most having received training during residency or fellowship. 70% of respondents stated they currently interpret pelvic endometriosis MRI, with most having 1-5 years of experience. Conclusion: Many radiologists in Canada do not perform dedicated imaging for endometriosis. This may be due to a lack of understanding of the benefits and limited access to training. However, dedicated imaging can improve patient outcomes and decrease repeated surgeries. The results highlight the importance of developing guidelines for these imaging techniques and promoting a multidisciplinary approach to endometriosis management.

Published: June 2023

Background We describe 12 cases of chlamydial ophthalmia neonatorum and the current scientific evidence on its prevention and treatment. The data presented were obtained from the “Maduo” study, a prospective observational study of the relationship between curable sexually transmitted infections and adverse neonatal outcomes at four antenatal clinics in Gaborone, Botswana. Methods Infants of mothers with perinatal chlamydia infection were evaluated for chlamydial ophthalmia neonatorum based on clinical presentation of conjunctivitis or positive test via GeneXpert CT/NG assay. Data on 29 infants born to mothers with postnatal C. trachomatis infection were analysed. Results 12 infants were diagnosed with chlamydial ophthalmia neonatorum. Eight of those cases were confirmed with the GeneXpert CT/NG assay while four were identified as probable cases based on clinical history and presentation. Overall, nine infants presented with signs of conjunctivitis, while three who had a positive diagnostic test result had asymptomatic infection. All but one infant had received ocular 1% tetracycline prophylaxis at birth, and four infants had signs suggestive of chlamydial pneumonia at presentation. Two out of five symptomatic cases whose mothers reported completion of their treatment course with erythromycin had lingering symptoms. Conclusions Our findings affirm that the current prophylaxis and treatment modalities for chlamydial ophthalmia neonatorum are inadequate. To the extent feasible in low- and middle-income countries, we recommend implementation of routine C. trachomatis screening and treatment in pregnant women.
Continuous infusion ketamine for sedation of mechanically ventilated adults in the intensive care unit: A scoping review
Authors: Richards Nicholas David , Weatherhead William , Howell Simon , Bellamy Mark , Mujica-Mota Ruben 
Published: June 2023

Introduction: Mechanical ventilation (MV) is a common and often live-saving intervention on the Intensive Care Unit (ICU). The optimisation of sedation to mechanical ventilation is fundamental, and inappropriate sedation has been associated with worse outcomes. This scoping review has been designed to answer the question ‘ What is known about the use of ketamine as a continuous infusion to provide sedation in mechanically ventilated adults in the intensive care unit, and what are the gaps in the evidence?’ Methods: The protocol was designed using the PRISMA-ScR checklist and the JBI manual for evidence synthesis. Data were extracted and reviewed by a minimum of two reviewers. Results: Searches of electronic databases (PubMed, OVID, Scopus, Web of Science) produced 726 results; 45 citations were identified for further eligibility assessment, an additional five studies were identified through keyword searches, and 12 through searching reference lists. Of these 62 studies, 27 studies were included in the final review: 6 case reports/case series, 11 retrospective cohort/observational studies, 1 prospective cohort study, 9 prospective randomised studies. Conclusion: We found a lack of high-quality well-designed studies investigating the use of continuous ketamine sedation on ICU. The available data suggests this intervention is safe and well tolerated, however this is of very low certainty given the poor quality of evidence.

Published: June 2023

Background: The Rome proposal provides an objective assessment tool for severity of acute exacerbation of chronic obstructive pulmonary disease (AE-COPD) but requires validation. Objectives: We aimed to evaluate the predictive performance of the Rome proposal in patients with AE-COPD. Design: This observational study assessed the patients who visited the emergency room (ER) or were hospitalized due to AE-COPD between January 2010 and December 2020. Methods: We compared the performance of the Rome Proposal with that of the DECAF score or GesEPOC 2021 criteria in predicting intensive care unit (ICU) admission, need for non-invasive ventilation (NIV) or invasive mechanical ventilation (IMV), and in-hospital mortality. Results: A total of 740 events of ER visit or hospitalization due to AE-COPD were reviewed and classified into mild (30.9%), moderate (58.6%), or severe (10.4%) group according to the Rome proposal. The severe group had a higher rate of ICU admission, required more NIV or IMV, and had a higher in-hospital mortality than the mild and moderate groups. The predictive performance of the Rome proposal was significantly better for ICU admission [area under the receiver operating characteristic curve (AU-ROC) = 0.850 versus 0.736, p = 0.004] and need for NIV or IMV (AU-ROC = 0.870 versus 0.770, p = 0.004) than that of the GesEPOC 2021 criteria but better than that of the DECAF score only in female patients. There was no significant difference in predicting the in-hospital mortality between the Rome proposal and DECAF score or GesEPOC 2021 criteria. Conclusion: External validation of the Rome Proposal in Korean patients demonstrated excellent performance for ICU admission and need for NIV or IMV and an acceptable performance for in-hospital mortality.
Identification of Core Outcome Domains and Design of a Survey Questionnaire to Evaluate Impacts of Digital Health Solutions That Matter to People With Diabetes
Authors: Skovlund Soren Eik , Renza Scibilia , Laurent Julie , Cerletti Paco 
Published: June 2023

Background: Digital health solutions (DHS) are increasingly used to support people with diabetes (PwD) to help manage their diabetes and to gather and manage health and treatment data. There is a need for scientifically reliable and valid methods to measure the value and impact of DHS on outcomes that matter to PwD. Here, we describe the development of a survey questionnaire designed to assess the perceptions of PwD toward DHS and their prioritized outcomes for DHS evaluation. Method: We applied a structured process for engagement of a total of nine PwD and representatives of diabetes advocacy organizations. Questionnaire development consisted of a scoping literature review, individual interviews, workshops, asynchronous virtual collaboration, and cognitive debriefing interviews. Results: We identified three overarching categories of DHS, which were meaningful to PwD and crucial for the identification of relevant outcomes: (1) online/digital tools for information, education, support, motivation; (2) personal health monitoring to support self-management; (3) digital and telehealth solutions for engaging with health professionals. Overall outcome domains identified to be important were diabetes-related quality of life, distress, treatment burden, and confidence in self-management. Additional positive and negative outcomes specific to DHS were identified and corresponding questions were incorporated into the survey questionnaire. Conclusion: We identified the need for self-reporting of quality of life, diabetes distress, treatment burden, and confidence in self-management, as well as specific positive and negative impacts of DHS. We designed a survey questionnaire to further assess the perceptions and perspectives of people with type 1 and 2 diabetes on outcomes relevant for DHS evaluations.
