Published: September 2020

AbstractThe purpose of this study was to provide an overview of entry screening measures applied at airports in response to the COVID-19 epidemic worldwide. Between 24 January and 17 February 2020, 5.2% (95% CI 3.1–8.5) of the 271 total imported COVID-19 cases worldwide (excluding imported cases arriving in China, Macao, and Hong Kong) with known detection location were captured through airport entry screening. The majority of imported COVID-19 cases (210) were identified by the health care system (77.5%). Efforts should focus on health care system preparedness for early case detection, since according to our and previous studies health care facilities are the actual point of entry of imported cases.

Published: September 2020

Abstract
Background
In this study, the traditional “Anatomical Landmark-Distance Method (AL-DM)” in the formation of joint line (JL) was compared with “Adductor Tubercle-Ratios method” (AT-RM), and the effect of reestablishment of JL on clinical and functional outcomes were evaluated.

Materials and methods
16 revision total knee arthroplasties (rTKAs) were performed by using “AT-RM” (group 1) and 16 rTKA by using “AL-DM” (group 2) in our clinic between 2015 and 2018. The data were prospectively collected and a total of 32 knees of 31 patients were analyzed. At the final follow-up, knee functions were evaluated by using Knee Society Score (KSS) knee and function, Western Ontario and McMaster Universities Arthritis Index (WOMAC) scores, Short Form-36 (SF-36) questionnaires and physical examinations.

Results
Postoperative flexion arc was higher in Group 1. KSS knee and function scores were better in group 1. In group1, JL was reestablished successfully in all revision rTKAs in terms of ATJL and the tibial tubercle TT-JL ratios. The improvement in KSS knee and function scores and WOMAC scores were also better in group 1. Measurements showed that the improvement in KSS scores increased as AT-JL and TT-JL distances approached the calculated values.

Conclusion
“AT-RM” was shown to be superior to the traditional distance method in terms of JL reestablishment. Functional results and patient satisfaction increased when JL was reestablished.

Published: September 2020

PURPOSE: Electronic patient-reported outcomes (ePROs) can help clinicians proactively assess and manage their patients’ symptoms. Despite known benefits, there is limited adoption of ePROs into routine clinical care as a result of workflow and technologic challenges. This study identifies oncologists’ perspectives on factors that affect integration of ePROs into clinical workflows. METHODS: We conducted semistructured qualitative interviews with 16 oncologists from a large academic medical center, across diverse subspecialties and cancer types. Oncologists were asked how they currently use or could imagine using ePROs before, during, and after a patient visit. We used an inductive approach to thematically analyze these qualitative data. RESULTS: Results were categorized into the following three main themes: (1) selection and development of ePRO tool, (2) contextual drivers of adoption, and (3) patient-facing concerns. Respondents preferred diagnosis-based ePRO tools over more general symptom screeners. Although they noted information overload as a potential barrier, respondents described strong data visualization and ease of use as facilitators. Contextual drivers of oncologist adoption include identifying target early adopters, incentivizing uptake through use of ePRO data to support billing and documentation, and emphasizing benefits for patient care and efficiency. Respondents also indicated the need to focus on patient-facing issues, such as patient response rate, timing of survey distribution, and validity and reliability of responses. DISCUSSION: Respondents identified several barriers and facilitators to successful uptake of ePROs. Understanding oncologists’ perspectives is essential to inform both practice-level implementation strategies and policy-level decisions to include ePROs in alternative payment models for cancer care.
Association Among Blood Transfusion, Postoperative Infectious Complications, and Cancer-Specific Survival in Patients with Stage II/III Gastric Cancer After Radical Gastrectomy: Emphasizing Benefit from Adjuvant Chemotherapy

Published: September 2020

Abstract
Objectives
This study was designed to investigate the potential additive influence of perioperative blood transfusion (BTF) and postoperative infections on cancer-specific survival (CSS) in patients with stage II/III gastric cancer (GC) after radical gastrectomy.

Methods
The medical records of 2114 consecutive stage II/III GC patients who underwent curative resection and planned to receive adjuvant chemotherapy (AC) were retrospectively reviewed. The independent predictive factors for infections were identified using univariate and multivariate analyses. Cox regression analysis was used to assess any associations between BTF, infection and CSS.

Results
A total of 507 (24.0%) received perioperative BTF and 148 (7.0%) developed infections with BTF being identified as an independent predictor for infections. Both BTF and infections independently predicted poor CSS (hazard ratio [HR]: 1.193, 95% confidence interval [CI] 1.007–1.414; HR 1.323, 95% CI 1.013–1.727) and an additive effect was confirmed as patients who had both BTF and infection had even worse CSS. Further stratified analyses showed that complete AC (≥ 6 cycles) could significantly improve CSS in patients who had BTF and/or infection, which was comparable to those without BTF and/or infection (P = 0.496).

Conclusions
Infection was the most common complication after gastrectomy and BTF was identified as an independent risk factor. BTF was associated with shorter CSS in stages II/III GC, independent of infections, and receiving BTF and developing infections had an additive effect that was associated with even worse CSS. However, complete AC could significantly improve CSS in these patients. Thus, strategies designed to ensure the completion of AC, such as neoadjuvant chemotherapy, should be further investigated.

Published: September 2020

Background: In Sri Lanka, the disease burden of leptospirosis is estimated based on a routine notification system, which is predominated by patients ill enough to be hospitalized. The notification system does not function well with ambulatory patients in outpatient departments (OPDs). The objective of this study was to determine the prevalence of leptospirosis in an OPD setting in a regional public hospital in Sri Lanka to provide further estimation of disease burden estimations Methods: This study was conducted in the OPD of the Rathnapura Provincial General Hospital from August to September 2017. Suspected leptospirosis patients were recruited based on standardized criteria and tested using the microscopic agglutination test and quantitative polymerase chain reaction. The number of OPD patients was compared with the reported patient numbers with leptospirosis from the hospital during the same period as the denominator, and the 95% confidence interval was calculated for the proportions using Poisson distribution. Results: During the study period, of 2,960 fever patients presenting to the OPD, 33 (1.1%) were suspected to have leptospirosis; 8/33 suspected (22.3%) cases were confirmed as being due to leptospirosis. There were 82 notifications of leptospirosis cases from hospital inpatients during the same period, none from the OPD. The total missing proportion from the surveillance system was 28.6% (95% CI, 19.4-40.4%). Among OPD patients, 12 (36.4%) had been given antibiotics from a primary care center prior to the OPD visit. No OPD patient was admitted to the hospital for inward care. Conclusions: More than 25% of cases of leptospirosis were not identified because they were not sick enough to be admitted nor subjected to routine leptospirosis diagnostic testing. Antibiotics given without a specific, treatable diagnosis interferes with leptospirosis disease burden assessment. These data have public health implications if the sources of leptospirosis transmission are to be controlled.
Announcing High Prices to Deter Innovation
Authors: Marshall Guillermo , Parra Álvaro 
Published: September 2020

Price announcements—similar to the ones made by tech firms at media events—are effective in deterring innovation. By announcing (and setting) a high price, a firm increases its rivals’ short-run profits, reducing the rival firms’ incentives to innovate by magnifying their Arrow’s replacement effect. We show that the equilibrium prices are greater and research and development (R&D) investments lower relative to when price announcements cannot be used strategically. We call this the R&D deterrence effect of price and show that it induces equilibrium prices that may exceed the multiproduct monopoly prices and even dissipate the consumer benefits of innovation.

Published: September 2020

Objective:The aim of this systematic review was to assess the effects of different repositioning regimens on pressure ulcer (PU) incidence in at-risk adult individuals without existing PUs.Method:Using systematic review methodology, randomised controlled trials (RCTs), including cluster-RCTs, prospective non-RCTs, pre–post-studies and interrupted-time-series studies were considered. Specifically explored was the impact of the frequency of repositioning, use of repositioning systems and use of turning teams. The search was conducted in January 2019, using PubMed, CINAHL, SCOPUS, Cochrane and EMBASE databases. Data were extracted using a pre-designed extraction tool and analysis was undertaken using RevMan.Results:A total of 530 records were returned, of which 16 met the inclusion criteria. Half of studies were conducted in intensive care units (50%). The mean sample size was 629±604 participants. Frequency of repositioning was explored in nine studies. PU incidence was 8% (n=221/2834) for repositioning every 2–3 hours, versus 13% (n=398/3050) for repositioning every 4–6 hours. The odds ratio (OR) was 0.75 (95% confidence interval (CI): 0.61–0.90, p=0.03), suggesting that there is a 25% reduction in the odds of PU development in favour of more frequent repositioning. Use of a repositioning system was explored in three studies. PU incidence was 2% (17/865) for the repositioning system, versus 5.5% (51/926) for care without using the repositioning system. The OR was 0.26 (95% CI: 0.05–1.29, p=0.10); this finding was not statistically significant. Use of a turning team was explored in two studies. PU incidence was 11% (n=22/200) with use of a turning team versus 20% (n=40/200) for usual care. The OR was 0.49 (95% CI: 0.27–0.86, p=0.01) suggesting that there is a 51% reduction in the odds of PU development in favour of use of a turning team. Using GRADE appraisal, the certainty of the evidence was assessed as low.Conclusion:The results of this systematic review indicate that more frequent repositioning and use of a turning team reduce PU incidence. However, given the low certainty of evidence, results should be interpreted with caution.

Authors: Duan Hongjie , He Yanqi , Zhang Hengbo , Wang Fang , Chen Shuai , Wang Jue 
Published: September 2020

Objective: Necrotising soft-tissue infection is a rare but life-threatening infectious disease with high morbidity and mortality. It is typically caused by toxin-producing bacteria and characterised clinically by a very rapid progression of the disease with significant local tissue destruction. In this study, we intend to explore effective wound management to control the invasive infection and to decrease the high mortality. Method: This retrospective analysis explored the wound management and mortality in patients with necrotising soft-tissue infection. Extensive debridement, vacuum sealing drainage (VSD) with normal saline instillation combined with broad-spectrum or sensitive antibiotics, and supportive therapies were used. Results: All 17 patients included in the analysis survived. The microbiology of 11 patients was found to be polymicrobial. Of the patients, 14 were discharged with completely healed wounds and three were transferred to a local hospital after the systemic and invasive wound infection was controlled. Conclusion: Our experiences revealed the outstanding effect of VSD with instillation in removing the debris of necrotising tissue on the wound bed, in the continual and complete drainage of wound exudates, and in prompting wound healing.

Prediction of Air Flight Cancellation during COVID-19 using Deep Learning Methods
Authors: Bandyopadhyay Samir Kumar , Goyel Vishal , DUTTA SHAWNI 
Published: September 2020

Air traffic is vulnerable to external factors, such as oil crises, natural disasters, economic recessions and disease outbreaks due to COVID-19. This reason seems to have a more severe and more rapid impact on air traffic numbers as sudden increases in flight cancellations, aircraft groundings and travel bans. Various Airways loose revenues and it is difficult for them to sustain for a long period. This problem as been facing the entire world. The reductions in passenger numbers are significant. It is due to flights being cancelled or planes flying empty between airports. It is in turn massively reducing revenues for airlines and forced many airlines to lay off employees or declare bankruptcy. Airways also have to attempt refunding cancelled trips in order to diminish their losses. The airliner manufacturers and airport operators have also laid off employees. According to some commentators, this crisis is the worst ever encountered in the history of the aviation industry.
Aircraft cancellation prediction is accomplished by utilising deep learning framework. In this framework, two dissimilar recurrent neural networks are assembled as a single entity while inferring the prediction results. Long-short term memory (LSTM) and Gated Recurrent Unit (GRU) are employed to design the proposed predictive model. This predictive model is compared against traditional neural network based Multi-layer perceptron model. Experimental results indicated an accuracy of 98.7% by the proposed model.
Em busca do desenvolvimento territorial rural do Matopiba: uma análise do Cerrado
Authors: De Jesus Andrade Widmarck Julienne 
Published: September 2020

No Brasil, o crescimento da produção agrícola no Matopiba (Maranhão, Tocantins, Piauí e Bahia), nas últimas duas décadas, reascenderam o debate em torno do desenvolvimento territorial rural. Logo, este trabalho apresenta como hipótese, a ideia de que o crescimento econômico, a partir da produção agrícola, produz desenvolvimento socioeconômico rural. A análise em questão utiliza dados da produção agrícola, do produto interno bruto e do indicador Firjan de desenvolvimento municipal, para os períodos de 1999 a 2017. Em termos metodológicos, utilizamos duas técnicas de exame de dados: a econometria espacial e a análise de dados em painel (GMM). Os resultados encontrados revelam um transbordamento do crescimento econômico para o tecido social, com ressalvas apenas no aumento da desigualdade de renda.
Estar y producir en colectivo. Reflexiones sobre los saberes desde la experiencia de los Espacios de Formación Integral de la Universidad de la República
Authors: Cavalli Dalla Rizza Valeria 
Published: September 2020

En el presente artículo compartimos algunas reflexiones epistemológicas y teóricas en torno a la integralidad como perspectiva que requiere una transformación en la concepción de la ciencia y la enseñanza universitaria y que apuesta a coproducir conocimiento desde el diálogo de saberes. Nos centramos en la experiencia de los Espacios de Formación Integral de la Universidad de la República como dispositivos pedagógicos que favorecen la relación entre los sujetos y sus saberes y disponen a producir colectivamente desde el estar y ser juntos y juntas. Asimismo, introducimos algunos abordajes metodológicos y estrategias didácticas que promueven la participación y la coproducción. Finalmente, problematizamos sobre la propia noción de diálogo de saberes, pensándolo como meta y guía de la integralidad, y planteamos que los Espacios de Formación Integral permiten producir prácticas educativas a partir del diálogo entre actores y actoras involucrados.
Capturing associations in graphs
Authors: Fan Wenfei , Jin Ruochun , Liu Muyang , Lu Ping , Tian Chao , Zhou Jingren 
Published: September 2020

This paper proposes a class of graph association rules, denoted by GARs, to specify regularities between entities in graphs. A GAR is a combination of a graph pattern and a dependency; it may take as predicates ML (machine learning) classifiers for link prediction. We show that GARs help us catch incomplete information in schemaless graphs, predict links in social graphs, identify potential customers in digital marketing, and extend graph functional dependencies (GFDs) to capture both missing links and inconsistencies.
We formalize association deduction with GARs in terms of the chase, and prove its Church-Rosser property. We show that the satisfiability, implication and association deduction problems for GARs are coNP-complete, NP-complete and NP-complete, respectively, retaining the same complexity bounds as their GFD counterparts, despite the increased expressive power of GARs. The incremental deduction problem is DP-complete for GARs versus coNP-complete for GFDs. In addition, we provide parallel algorithms for association deduction and incremental deduction. Using real-life and synthetic graphs, we experimentally verify the effectiveness, scalability and efficiency of the parallel algorithms.
