Development and application of ‘systems thinking’ principles for quality improvement
Authors: McNab Duncan , McKay John , Shorrock Steven , Luty Sarah , Bowie Paul
Published: March 2020

Introduction

‘Systems thinking’ is often recommended in healthcare to support quality and safety activities but a shared understanding of this concept and purposeful guidance on its application are limited. Healthcare systems have been described as complex where human adaptation to localised circumstances is often necessary to achieve success. Principles for managing and improving system safety developed by the European Organisation for the Safety of Air Navigation (EUROCONTROL; a European intergovernmental air navigation organisation) incorporate a ‘Safety-II systems approach’ to promote understanding of how safety may be achieved in complex work systems. We aimed to adapt and contextualise the core principles of this systems approach and demonstrate the application in a healthcare setting.

Methods

The original EUROCONTROL principles were adapted using consensus-building methods with front-line staff and national safety leaders.

Results

Six interrelated principles for healthcare were agreed. The foundation concept acknowledges that ‘most healthcare problems and solutions belong to the system’. Principle 1 outlines the need to seek multiple perspectives to understand system safety. Principle 2 prompts us to consider the influence of prevailing work conditions—demand, capacity, resources and constraints. Principle 3 stresses the importance of analysing interactions and work flow within the system. Principle 4 encourages us to attempt to understand why professional decisions made sense at the time and principle 5 prompts us to explore everyday work including the adjustments made to achieve success in changing system conditions.

A case study is used to demonstrate the application in an analysis of a system and in the subsequent improvement intervention design.

Conclusions

Application of the adapted principles underpins, and is characteristic of, a holistic systems approach and may aid care team and organisational system understanding and improvement.

Published: March 2020

Recent studies have shown that the glucagon receptor (GCGR) plays an important role in the development of type 2 diabetes mellitus. Both pigs and humans exhibit significantly similar behaviors in their glucose and lipid metabolism. In this study, the obtained Bama minipig GCGR coding sequence was 1437 bp encoding 479 amino acids (AA), which demonstrated higher sequence homology with humans than other species. It showed the highest expression profile in the liver, followed by the lung and kidney. In addition, the three-dimensional structure analysis showed that the porcine GCGR protein also had a classic sevenfold transmembrane region and a stalk region at the N-terminus for ligand binding. The stalk region of GCGR possessed five AA variations. The ligand binding pocket of GCGR has one AA variation in the key region, none of which affected the glucagon binding verified by the crystal structure mutagenesis in humans. There was no variation found in the region of membrane anchoring, hydrophobic bond, salt bridge, and hydrogen bond. However, the Gly40Ser mutation in mice resulted in major diseases, meaning that pigs are more suitable for the evaluation of GCGR-related drugs than mice.
Hiding in plain sight: experimental evidence for birds as selective agents for host mimicry in mistletoes
Authors: Cook M.E. , Leigh A. , Watson D.M.
Published: March 2020

Many Australian mistletoe species are cryptic, closely resembling their host foliage and overall appearance. Seed-dispersing birds have been proposed as a selective agent for host resemblance, with cryptic mistletoes only located by thoroughly searching through canopies regardless of infection status, boosting mistletoe populations by increasing the frequency of seeds dispersed to uninfected hosts; however, this idea is as yet untested. We measured bird visitation to fruiting mistletoes (n = 20) over two consecutive days, with manual defoliation of the mistletoe occurring before observation began on the second day to determine the effect of the visual appearance of the mistletoe on potential seed-dispersing birds, expecting defoliation to reduce the number of visits. Visits to the mistletoes were compared between days of observation and dietary guild (mistletoe specialist/nonspecialist). Intact mistletoes were visited more than the defoliated mistletoes, and the dietary guilds differed in their visitation patterns. This work demonstrates that the visual acuity of seed-dispersers can distinguish subtle differences in mistletoe phenotypes within infected hosts, consistent with the hypothesis that those mistletoes that more closely resemble their hosts are more difficult to perceive from afar and therefore more likely to have their seeds dispersed to uninfected hosts.
One-Bit ΣΔ-Encoded Stimulus Generation for On-Chip ADC Test
Authors: Ahmad Shakeel , Dąbrowski Jerzy
Published: March 2020

This paper presents an application of the [Formula: see text] modulation technique to the on-chip dynamic test for analog-to-digital converters (ADCs). The required stimulus such as a single- or two-tone signal is encoded into one-bit [Formula: see text] sequence, which is applied to an ADC under test through a driving buffer and a simple low-pass reconstruction filter. By a systematic approach, we select the order and type of a [Formula: see text] modulator and develop a frequency plan suitable for the spectral measurement. In this way, we achieve a high dynamic range suitable for spectral harmonic and intermodulation distortion tests for ADCs. For high frequency measurements (up to the Nyquist frequency), we propose a novel low-pass/band-pass modulation scheme that allows to avoid harmful effects of the low-frequency quantization noise. Also we address the distortion components which originate from the buffer imperfections for a nonreturn-to-zero waveform representing the encoded stimulus. We show that the low-frequency distortion components can be cancelled by using a simple iterative predistortion technique supported by measurements with a DC-calibrated ADC. By correlation between low- and high-frequency components also the high frequency distortions can be largely reduced. The presented techniques are illustrated by simulation results of an ADC under test.
Exact solutions for compact stars with CFL quark matter
Authors: Rocha L. S. , Bernardo A. , De Avellar M. G. B. , Horvath J. E.
Published: March 2020

The search for the true ground state of the dense matter remains open since Bodmer, Terazawa and others raised the possibility of stable quark matter, boosted by Witten’s strange matter hypothesis in 1984. Within this proposal, the strange matter is assumed to be composed of [Formula: see text] quarks in addition to the usual [Formula: see text]s and [Formula: see text]s, having an energy per baryon lower than the strangeless counterpart, and even lower than that of nuclear matter. In this sense, neutron stars should actually be strange stars. Later work showed that a paired, symmetric in flavor, color-flavor locked (CFL) state would be preferred to the one without any pairing for a wide range of the parameters (gap [Formula: see text], strange quark mass [Formula: see text] and bag constant B). We use an approximate, yet very accurate, CFL equation-of-state (EoS) that generalizes the MIT bag model to obtain two families of exact solutions for the static Einstein Field Equations (EFE) constructing families of anisotropic compact relativistic objects. In this fashion, we provide exact useful solutions directly connected with microphysics.
Down closed injectivity and essentialness
Authors: Shahbaz Leila , Mahmoudi Mojgan
Published: March 2020

Injectivity is one of the useful notions in algebra, as well as in many other branches of mathematics, and the study of injectivity with respect to different classes of monomorphisms is crucial in many categories. Also, essentiality is an important notion closely related to injectivity. Down closed monomorphisms and injectivity with respect to these monomorphisms, so-called dc-injectivity, were first introduced and studied by the authors for [Formula: see text]-posets, posets with an action of a pomonoid [Formula: see text] on them. They gave a criterion for dc-injectivity and studied such injectivity for [Formula: see text] itself, and for its poideals. In this paper, we give results about dc-injectivity of [Formula: see text]-posets, also we find some homological characterization of pomonoids and pogroups by dc-injectivity. In particular, we give a characterization of pomonoids over which dc-injectivity is equivalent to having a zero top element. Also, introducing the notion of [Formula: see text]-injectivity for [Formula: see text]-posets, where [Formula: see text] and [Formula: see text] is externally adjoined to the posemigroup [Formula: see text], we find some classes of pomonoids such that for [Formula: see text]-posets over them the Baer Criterion holds. Further, several kinds of essentiality of down closed monomorphisms of [Formula: see text]-posets, and their relations with each other and with dc-injectivity is studied. It is proved that although these essential extensions are not necessarily equivalent, they behave almost equivalently with respect to dc-injectivity. Finally, we give an explicit description of dc-injective hulls of [Formula: see text]-posets for some classes of pomonoids [Formula: see text].
DO HIGH-PERFORMANCE WORK PRACTICES INDUCE INNOVATIVE WORK BEHAVIOUR? THE CASE OF THE QATARI BANKING SECTOR
Authors: OBEIDAT SHATHA M.
Published: March 2020

Purpose: This paper presents results from an empirical study in the banking sector in Qatar on the impact of high-performance work practices (HPWPs) on employee’s innovative work behaviour (IWB). In particular, the study seeks to examine the impact of HPWP on employees work attitudes of job satisfaction and organisational commitment, and of the possible mediating link of employees’ attitudes (i.e., satisfaction and commitment) on HPWPs and IWB link.

Methodology: Data were collected from employees about their perception of the use of HPWPs in their banks and about their level of satisfaction at work, their perceived commitment, and their innovative work behaviour. The sample included 150 employees working in different banks at Qatar.

Findings: The findings suggest that HPWPs are positively related to job satisfaction, organisational commitment, and IWB. Also, the study provides support for the mediating effect of organisational commitment on the HPWPs and IWB link.

Practical implications: When trying to inspire employees IWB through managerial practices (like HPWPs) in Qatari banks, management needs to pay attention to employees work related attitudes such as job satisfaction and organisational commitment.

Limitations: The unique characteristics of the Qatari banks limits the generalizability of the study findings.

Originality: This is the first study that explores the mediating role of job satisfaction and organisational commitment on HPWPs-IWB link after conducting a comprehensive PLS analysis. Moreover, the study provides evidence of this possible link in what is believed to be unique study setting.

Let [Formula: see text] be a topological space admitting an amenable cover of multiplicity [Formula: see text]. We show that, for every [Formula: see text] and every [Formula: see text], the image of [Formula: see text] in the [Formula: see text]-homology module [Formula: see text] vanishes. This strengthens previous results by Gromov and Ivanov, who proved, under the same assumptions, that the [Formula: see text]-seminorm of [Formula: see text] vanishes.
Efficient Hierarchical Authentication Protocol for Multiserver Architecture
Authors: Kou Jiangheng , He Mingxing , Xiong Ling , Lv Zeqiong
Published: March 2020

The multiserver architecture authentication (MSAA) protocol plays a significant role in achieving secure communications between devices. In recent years, researchers proposed many new MSAA protocols to gain more functionality and security. However, in the existing studies, registered users can access to all registered service providers in the system without any limitation. To ensure that the system can restrict users that are at different levels and can access to different levels of service providers, we propose a new lightweight hierarchical authentication protocol for multiserver architecture using a Merkle tree to verify user’s authentication right. The proposed protocol has hierarchical authentication functionality, high security, and reasonable computation and communication costs. Moreover, the security analysis demonstrates that the proposed protocol satisfies the security requirements in practical applications, and the proposed protocol is provably secure in the general security model.

Published: March 2020

This study is aimed at exploring the relationship between serum ferritin and blood lipids and the influence of diabetes and different hs-CRP levels. A total of 8163 subjects were analyzed. Participators were classified according to serum ferritin, diabetes, and two hs-CRP levels. Blood lipids were determined using standardized methods and conditions. Except for HDL-C, there was a significant increase in blood lipids in the progressive ferritin group with normal hs-CRP levels (P<0.05). But HDL-C was just the opposite (P<0.0001). In nondiabetic patients, TG, TC, and LDL-C were significantly elevated in the progressive ferritin group (P<0.05). And, HDL-C was just the opposite (P<0.05). The generalized linear model and the parsimonious model showed that serum TG was positively correlated with ferritin, and LDL-C was negatively correlated with ferritin (P<0.05). But the correlation between LDL-C and ferritin was broken (P>0.05). After a sufficient adjustment, there was a positive correlation between serum TG and ferritin and a negative correlation between LDL-C and ferritin. Nonetheless, a negative correlation between LDL-C and ferritin is influenced by diabetes frailly. And, there was no change of relationship between lipids and ferritin in different hs-CRP levels. We found a real relationship between ferritin and lipids after sufficient adjustment for confounders.

Published: March 2020

The National Free Antiretroviral Therapy (ART) Program in China has initiated to provide ART to HIV‐1 patients, which has acted as an efficient method to suppress viral replication and helps prevent onward transmissions. But the problems of HIV drug resistance (HIVDR) may also come along. There is little data on the prevalence of HIVDR in Chengdu, where the number of HIV/AIDS patients ranks first among provincial capitals. Therefore, epidemiological surveillance was conducted in this area. From 2014 to 2016, HIV/AIDS patients (15 years and older) who had received first‐line ART for at least six months were enrolled. Demographic, behavioral information and medical history were recorded, and blood samples were collected for viral loads and immune cell count analyses. HIV‐1 pol was obtained for HIV‐1 subtypes and drug resistance‐associated mutations (DRMs) among virologic failure patients. A total of 13,782 individuals were enrolled, and 481 samples were sequenced for subtypes and drug resistance analysis. Six subtypes were identified, among which CRF01_AE (54.3%) and CRF07_BC (41.6%) were the dominant subtypes, and CRF55_01B (0.4%) was detected in Chengdu for the first time. The prevalence of HIVDR in treatment‐experienced patients was 1.8%, with 1.2% to nucleoside reverse transcriptase inhibitors (NRTIs), 1.7% to non‐NRTIs (NNRTIs), and 0.14% to protease inhibitors (PIs). The leading DRMs observed in the study were M184I/V (59.59%) against NRTIs and K103N (37.55%) against NNRTIs. This study focused on the HIVDR surveillance among patients receiving treatment in Chengdu. The overall prevalence of HIVDR was relatively low among treated patients. These findings were believed to be contributed to an understanding of HIV‐1 subtypes, HIVDR prevalence, and DRMs in Chengdu and thereby optimizing clinical management, prevention, and control of HIV.
An Effective Retinal Blood Vessel Segmentation by Using Automatic Random Walks Based on Centerline Extraction
Authors: Gao Jianqing , Chen Guannan , Lin Wenru
Published: March 2020

The retinal blood vessel analysis has been widely used in the diagnoses of diseases by ophthalmologists. According to the complex morphological characteristics of the blood vessels in normal and abnormal images, an automatic method by using the random walk algorithms based on the centerlines is proposed to segment retinal blood vessels. Hessian‐based multiscale vascular enhancement filtering is used to display the vessel structures in maximum intensity projection. Random walk algorithm provides a unique and quality solution, which is robust to weak object boundaries. Seed groups in the random walk segmentation are labeled according to the centerlines, which are extracted by using the divergence of the normalized gradient vector field and the morphological method. Experiments of the proposed method are implemented on the publicly available STARE (the Structured Analysis of the Retina) database. The results are compared to other existing retinal blood vessel segmentation methods with respect to the accuracy, sensitivity, and specificity, and the proposed method is proved to be more sensitive in detecting the retinal blood vessels in both normal and pathological areas.
Nomogram Based on microRNA Signature Contributes to Improve Survival Prediction of Clear Cell Renal Cell Carcinoma
Authors: Zhao Enfa , Bai Xiaofang
Published: March 2020

Objective. Numerous microRNAs (miRNAs) have been identified in ccRCC and recommended to be used for predicting clear cell renal cell carcinoma (ccRCC) prognosis. However, it is not clear whether a miRNA‐based nomogram results in improved survival prediction in patients with ccRCC. Methods. miRNA profiles from tumors and normal tissues were downloaded from The Cancer Genome Atlas (TCGA) database and analyzed using the “limma” package. The association between differentially expressed miRNAs and patient prognosis was identified using univariate, least absolute shrinkage and selection operator (LASSO), and multivariate Cox regression analyses. Next, all patients were randomly divided into development and validation cohorts at a ratio of 1 : 1. A nomogram was established based on independent prognostic factors in the development cohort. The prognostic performance of the nomogram was validated in both cohorts using the concordance index (C‐index) and calibration plots. Results. Multivariate Cox analysis identified the 13‐miRNA signature, as well as AJCC stage and age, as independent prognostic factors after adjusting for other clinical covariates. The nomogram was built based on the independent variables. In the development cohort, the C‐index for the constructed nomogram to predict overall survival (OS) was 0.792, which was higher than the C‐index (0.731) of the AJCC staging system and C‐index (0.778) of the miRNA signature. The nomogram demonstrated good discriminative ability in the validation cohort in predicting OS, with a C‐index of 0.762. The calibration plots indicated an excellent agreement between the nomogram predicted survival probability and the actual observed outcomes. Furthermore, decision curve analysis (DCA) indicated that the nomogram was superior to the AJCC staging system in increasing the net clinical benefit. Conclusions. The novel proposed nomogram based on a miRNA signature is a more reliable and robust tool for predicting the OS of patients with ccRCC compared to AJCC staging system, thus, improving clinical decision‐making.

Published: March 2020

We present a case of an 82-year-old female with a history of right total knee arthroplasty 11 years prior. She was admitted after a ground-level fall and developed progressive pain and swelling of her right knee. She had no history of complications with her total knee replacement. Radiographs of the knee and hip were negative for acute fracture, dislocation, or hardware malalignment. Knee aspiration was performed and revealed inflammatory exudate, synovial fluid consistent with crystal arthropathy, and no bacterial growth. She was diagnosed with an acute gout flare, and her symptoms significantly improved with steroids and anti-inflammatory treatment. Orthopedic surgeons should be aware of the potential for crystal arthropathy in the setting of total joint arthroplasty and evaluate for crystals before treating a presumed periprosthetic joint infection.

Despite major advancements in genomic medicine, research to optimize the design and communication of genetically informed interventions in behavioral health has lagged. The goal of this study was to engage potential end users in participatory codesign of a personalized genetically informed risk tool to intervene on high-risk health behaviors. We used structured interviews to examine end-user attitudes and interest in personalized genetics, qualitative interviews to guide iterative design of a genetically informed tool, and questionnaires to assess acceptability and potential utility of the tool. Participants expressed strong demand for using personal genetics to inform smoking and alcohol-related disease risk and guide treatment (78%–95% agreed). Via iterative design feedback, we cocreated a genetically informed risk profile featuring (i) explanation of genetic and phenotypic markers used to construct a risk algorithm, (ii) personalized risks and benefits of healthy behavior change, and (iii) recommended actions with referral to freely available resources. Participants demonstrated sufficient understanding and cited motivating behavior change as the most useful purpose of the tool. In three phases, we confirmed strong desire for personalized genetics on high-risk health behaviors; codesigned a genetically informed profile with potential end users; and found high acceptability, comprehensibility, and perceived usefulness of the profile. As scientific discovery of genomic medicine advances in behavioral health, we must develop the tools to communicate these discoveries to consumers who stand to benefit. The potential of genomic medicine to engage populations and personalize behavioral health treatment depends, in part, on preparatory studies to design for the future implementation of genetically informed interventions.

Published: March 2020

Therapy-related acute myeloid leukemia (AML) is a rare but potentially fatal adverse event caused by chemotherapy or radiotherapy. Herein we report a patient diagnosed with therapy-related AML 2 months after chemoradiotherapy for esophageal cancer. A 61-year-old man with dysphagia was diagnosed with locally advanced esophageal cancer with para-aortic lymph node metastasis. Laboratory blood test did not reveal any abnormality except mild macrocytic anemia. To alleviate dysphagia due to malignant esophageal stenosis, the patient underwent concurrent chemoradiotherapy of 60 Gy in 30 fractions with cisplatin and 5-fluorouracil at a local area in thoracic esophagus. Dysphagia alleviated during chemoradiotherapy; however, pancytopenia did not recover after the completion of chemoradiotherapy, and general fatigue with fever developed 13 weeks after the last day of chemoradiotherapy. To rule out hematological malignancy, bone marrow biopsy was performed. The bone marrow smear and flow cytometry analysis indicated the development of AML. Chromosomal test revealed a complex karyotype, suggesting that AML was associated with myelodysplastic syndrome. The patient died 1 month after the diagnosis of therapy-related AML. Thus, the findings indicate that therapy-related AML may develop during the acute phase of chemoradiotherapy and bone marrow biopsy is necessary when prolonged pancytopenia exists after chemoradiotherapy.

Chronic myelogenous leukemia (CML), also known as chronic myeloid leukemia, is a myeloproliferative neoplasm characterized by increased proliferation of the granulocytic cell line without loss of its capacity to differentiate. It accounts for 20% of all adults affected by leukemia. Tyrosine kinase inhibitors revolutionized the treatment for CML and improved quality of life. Fertility is an important issue for both males and females. Here, we report our experience with a pregnant female with CML, and shed light on safety and efficacy of PEGylated interferon-αa in pregnant women with CML and its outcome.

Design and Implementation of Video Shot Detection on Field Programmable Gate Arrays
Authors: Majumdar Jharna , K M Darshan , Vijayendra Abhijith
Published: March 2020

Video has become an interactive medium of communication in everyday life. The sheer volume of video makes it extremely difficult to browse through and find the required data. Hence extraction of key frames from the video which represents the abstract of the entire video becomes necessary. The aim of the video shot detection is to find the position of the shot boundaries, so that key frames can be selected from each shot for subsequent processing such as video summarization, indexing etc. For most of the surveillance applications like video summery, face recognition etc., the hardware (real time) implementation of these algorithms becomes necessary. Here in this paper we present the architecture for simultaneous accessing of consecutive frames, which are then used for the implementation of various Video Shot Detection algorithms. We also present the real time implementation of three video shot detection algorithms using the above mentioned architecture on FPGA (Field Programmable Gate Arrays).

Partículas modais em alemão e seus equivalentes funcionais em português brasileiro: proposta de análise e classificação para o uso
Authors: Aquino Marceli Cherchiglia , Arantes Poliana Coeli Costa
Published: March 2020

Neste artigo intencionamos realizar uma análise contrastiva de ocorrências de partículas modais (doravante PM) em alemão, catalão, croata, francês e inglês, propondo uma classe de PM para o português brasileiro. Partimos de referencial teórico com base na pragmática e em teorias funcionalistas como suporte. Nosso principal objetivo é defender a existência de PMs no português brasileiro, sendo elas recursos linguístico-discursivos utilizados com a função de modalizar informações não explícitas durante a interação. Nesse sentido, as PMs ativariam pressupostos nas enunciações baseados em significados nucleares. Trata-se de estudo inédito por propor análises de palavras e locuções que ainda não foram classificadas como tal em gramáticas luso-brasileiras, salvo algumas poucas exceções. O presente estudo justifica-se pela dificuldade que essas PM apresentam tanto para o ensino de língua adicional, quanto para a tradução. A investigação e descrição das PMs alemãs e seus equivalentes funcionais em português, podem, portanto, oferecer caminhos para a compreensão de questões pragmáticas importantes para as trocas comunicativas e seus usos em sala de aula. Finalmente, levantamos a hipótese de que, embora exista uma evidente diferença de classificação dessas partículas em muitas línguas, as funções comunicativas das PMs em alemão podem encontrar semelhantes interpretativos e até equivalentes funcionais em português brasileiro.
“Viver numa casa de vidro é uma virtude revolucionária por excelência” : Walter Benjamin e a paixão pela cidade e pela história “ porosas ”
Authors: Seligmann-Silva Marcio
Published: March 2020

Walter Benjamin escreveu muito sobre cidades e arquitetura ao longo de sua obra. Seja em jornais de viagens, em ensaios dedicados a determinadas formações urbanas, em textos autobiográficos, na sua teoria do flâneur, ou em sua teoria estética, as cidades sempre estiveram em um local central. A cidade ideal de Benjamin não é clássica, “bela”, mas, antes, marcada pela circulação de pessoas, pela “interpenetração” (Durchdringung) e pela “porosidade”. Essa cidade perfurada se metamorfoseia em sua própria filosofia da história, já que pare ele também o tempo é poroso.
Leituras facilitadas como mediação linguística no ensino/aprendizagem de alemão como língua estrangeira
Authors: Cândido Abdalan Da Gama , Evangelista Maria Cristinal Reckziegel Guedes
Published: March 2020

Analisando convergências entre o uso da tradução no ensino de línguas e a prática com livros de leitura facilitada (LLFs), postulamos que a facilitação que constitui esses livros pode ser vista como uma forma de tradução, conhecida por mediação linguística (em alemão, Sprachmittlung). Para aprofundar os estudos sobre os LLFs e considerando o interesse dos aprendizes de alemão como língua estrangeira pela literatura em língua alemã, analisamos uma obra facilitada para nível B1 e a comparamos com o texto original. A obra escolhida foi Die Verwandlung, de Franz Kafka, adaptada por Achim Seiffarth (2003). Utilizando ferramentas computacionais, geramos dados quantitativos ligados à linguística de corpus, buscando verificar em que medida o perfil lexical e as características estruturais dessa obra contribuem para a facilitação do texto. Como resultado, entendemos que o livro de leitura facilitada (LLF) analisado aproxima os aprendizes do texto e pode contribuir para a expansão de seu vocabulário, realizando, portanto, a mediação linguística. Além disso, os LLFs tornam possível a leitura de clássicos da literatura em língua alemã nos estágios intermediários de aprendizagem dessa língua, que de outra forma seria difícil ou impossível.

Após mais de 60 anos de evolução, a inteligência artificial acelera seu desenvolvimento, impulsionada por novas tecnologias, devendo trazer grandes possibilidades aos países que a adotarem em larga escala. Este artigo apresenta uma visão geral das estratégias nacionais lançadas nos últimos anos, com o objetivo de ressaltar a importância de que o Brasil defina uma política pública para promover a adoção da inteligência artificial. Estudos recentes mostram que a disseminação das técnicas de inteligência artificial irá alargar ainda mais a desigualdade entre as nações, fazendo com que o atraso nessa área se torne um caminho sem volta.
Efficacy and safety of cryotherapy, cold cone or thermocoagulation compared to LEEP as a therapy for cervical intraepithelial neoplasia: Systematic review
Authors: Hurtado-Roca Yamilée , Becerra-Chauca Naysha , Malca Magaly
Published: March 2020

OBJECTIVES: To determine the efficacy and safety of the use of cryotherapy, cold knife or thermocoagulation compared to Loop Electrosurgical Excision Procedure (LEEP) for the treatment of cervical intraepithelial neoplasia. METHODS: Systematic review with meta-analysis of randomized controlled trials in women with cervical intraepithelial neoplasia undergoing treatment with cryotherapy, cold knife, or thermo-coagulation compared with LEEP, to estimate its efficacy and safety. The search was conducted on MEDLINE/PUBMED, Cochrane Central Register of Controlled Trials (CENTRAL) and Scopus, until September 2018. RESULTS: The total of 72 studies were identified, of which only 8 studies met the inclusion criteria. The treatment of CIN with cold knife decreases the risk of residual disease compared with LEEP (RR, 0.54, 95%CI, 0.30–0.96, p = 0.04). The management of premalignant lesions with cryotherapy, compared with LEEP, increases the risk of disease recurrence by 86% (RR, 1.86, 95%CI, 1.16–2.97, p = 0.01), increases the risk of infections (RR, 1.17, 95%CI, 1.08–1.28, p < 0.001) and reduces the risk of minor bleeding by 51% (RR, 0.49, 95%CI) %, 0.40–0.59, p ≤ 0.001). CONCLUSIONS: The treatment of premalignant lesions of cervical cancer with cold knife reduces the risk of residual disease. Nevertheless, cryotherapy reduces the risk of minor bleeding in the 24 hours after treatment and increases the risk of recurrence of disease and infections.

OBJECTIVE: Evaluate socio-demographic, family and behavioral factors associated with oral health literacy (OHL) in adolescents. METHODS: Cross-sectional study conducted with adolescents aged 15 to 19 years in Campina Grande, Brazil. Parents/guardians answered a questionnaire addressing socio-demographic data. The adolescents answered validated instruments on family cohesion and adaptability (family adaptability and cohesion evaluation scale), drug use (alcohol, smoking and substance involvement screening test), type of dental service used for last appointment and OHL (Brazilian version of the Rapid Estimate of Oral Health Literacy in Dentistry). Two dentists were trained to evaluate OHL (K = 0.87–0.88). Descriptive analysis was performed, followed by Poisson regression analysis (α = 5%). A directed acyclic graph was used to select independent variables in the study. RESULTS: The following variables remained associated with better OHL: high mother’s schooling level (RR = 1.07; 95%CI: 1.03–1.12), high income (RR = 1.04; 95%CI: 1.01–1.09), white ethnicity/skin color (RR = 1.05; 95%CI: 1.01–1.10), married parents (RR = 1.04; 95%CI: 1.01–1.09), “enmeshed” family cohesion (RR = 1.21; 95%CI: 1.12–1.30), “structured” (RR = 1.06; 95%CI: 1.01–1.12) or “rigid” (RR = 1.11; 95%CI: 1.04–1.19) family adaptability, having more than five residents in the home (RR = 1.07; 95%CI: 1.01–1.14) and having used a private dental service during the last appointment (RR = 1.08; 95%CI: 1.03–1.13). CONCLUSION: Family functioning and socio-demographic factors influence the level of oral health literacy among adolescents.

Background:

Current guidelines recommend evaluation for underlying heart disease and reversible conditions for patients with new-onset heart failure (HF). There are limited data on contemporary testing for coronary artery disease (CAD) in patients with new-onset HF.

Methods:

We performed an observational cohort study using the Get With The Guidelines–Heart Failure registry linked to Medicare claims. All patients were aged ≥65 and hospitalized for new-onset HF from 2009 to 2015. We collected left ventricular ejection fraction (LVEF), prior HF history, and in-hospital CAD testing from the registry, as well as testing for CAD using claims from 90 days before to 90 days after index HF hospitalization.

Results:

Among 17 185 patients with new-onset HF, 6672 (39%) received testing for CAD, including 3997 (23%) during the index hospitalization. Testing for CAD differed by LVEF: 53% in HF with reduced EF (LVEF ≤40%), 42% in HF with borderline EF (LVEF, 41%–49%), and 31% in HF with preserved EF (LVEF ≥50%). After multivariable adjustment, patients who received testing for CAD, compared with those who did not, were younger and more likely to be male, have a smoking history, have hyperlipidemia, and have HF with reduced ejection fraction or HF with borderline ejection fraction (all
P
<0.05).

Conclusions:

The majority of patients hospitalized for new-onset HF did not receive testing for CAD either during the hospitalization or in the 90 days before and after. The rates of testing for CAD were higher in patients with LVEF ≤40% though remained low. These data highlight an opportunity to improve care by identifying appropriate candidates for optimal CAD medical therapy and revascularization.
KENTSEL PERİFERİNİN DÖNÜŞÜMÜ VE ENTEGRASYONUNDA STK’LARIN ÜSTLENEBİLECEĞİ ROLLER ÜZERİNE BİR DEĞERLENDİRME
Authors: NEBATİ Nureddin
Published: March 2020

Bu çalışmanın amacı, günümüz kent sorunlarını merkez ve çevre ikiliği üzerinden açıklayarak bu sorunların çözümü için STK’lar tarafından atılabilecek adımları genel hatlarıyla ortaya koymaktır. Kentlerin merkez ve çevre alanları kendilerine özgü yaşam tarzları, yerleşim biçimleri ve sorun alanları barındırmaktadır. Türkiye kentlerinde merkez ve periferi alanları tarihsel süreç içerisinde köyden kente göçle şekillenmiştir. Kentsel dönüşüm ile birlikte periferilerde görülen yaşam tarzları ve yerleşim biçimleri de dönüşmüştür. Periferi yeniden tanımlanmaya başlamıştır. Yeniden tanımlanma sürecinde oluşabilecek sorunları ortadan kaldırmada ve sürecin kontrol altında gitmesini sağlamada STK’lara önemli görevler düşmektedir. STK’lar yürütecekleri çeşitli program ve çalışmalarla periferinin sorunlarını rehabilite edebilir ve merkez ile çevrenin birbirine eklemlenmesini sağlayabilir. Böylece kentsel dönüşüm, fiziksel bir sürecin ötesine geçerek kentin her alanında görülen bir sosyal bütünleşmeye dönüşebilir.

Authors: KARAÖMER Yunus , OYPAN Oğuz
Published: March 2020

The aim of this study is to measure and evaluate the financial performance and brand values of six companies listed in the BIST Sustainability Index in 2014-2018 by using the Hirose method. Moreover, the Hirose method’s brand valuations are compared with brand valuation ranking the Brand Finance which are companies specialized in brand valuation, and ranking from the Brand Finance Turkey 100 in 2018. The Hirose method’s brand valuation is GARAN with the highest brand value in 2018, while the Brand Finance’s brand valuation is AKBNK with the highest brand value in 2018. According to the results of the analysis, there are differences between the Hirose method and Brand finance. The reason for this differences is that the Hirose method considers quantitative data, while the Brand Finance considers both quantitative data and qualitative variables.

“Be Suicided”: A Construction Grammar Analysis of the Innovative bèi Construction in Chinese
Authors: Chen Rong , Hu Xiaoxia
Published: March 2020

This paper is a construction grammar analysis of the innovative bèi construction in Chinese. The bèi construction departs from the canonical passive construction in that, instead of a transitive verb, it has a lexeme that is not a transitive verb to go with the passive marker bèi. We propose that the non-transitive verb denotes an event (as opposed to a state or action) in which the referent of the subject participates involuntarily. The passive semantics of the construction then coerces the non-transitive lexeme into behaving like one. We will, in addition, demonstrate a case of what may be called a “reverse constructional coercion” whereby the innovative construction imposes its semantics onto canonical passive sentences. Lastly, we argue that the structure and semantics of the construction create a parody of the social reality the construction seems to reflect. This parody, which is based on the similarities between the bèi construction and the canonical passive construction, in turn, produces the rhetorical effects of satire/sarcasm, expressing a sense of absurdity about the event in question and a sense of indignation and helplessness on the part of the speaker.
Combating Crime in the Digital Age: a Critical Review of EU Information Systems in the Area of Freedom, Security and Justice in the Post-Interoperability Era
Authors: Giannakoula Athina , Lima Dafni , Kaiafa-Gbandi Maria
Published: March 2020

This article provides a systematic and critical account of EU information systems in the area of freedom, security and justice, with the aim of establishing the contemporary links between information sharing and criminal law in the EU and of evaluating its impact on individuals. To this end, Part 1 offers a systemisation and critical assessment of the essential elements of the pertinent systems (ECRIS, ECRIS-TCN, Prüm, PNR, Europol, SIS, Eurodac, VIS, EES, ETIAS) and of the new interoperability regime under Regulation (EU) 2019/818, from the perspective of their objective to prevent and combat serious crime and to ensure a high level of security in the EU. In Part 2 the article explores personal data protection law, police law and criminal procedure law, in order to propose safeguards and limitations for effectively regulating this rapidly evolving framework and addressing the growing challenges for fundamental legal principles and individual rights. In this respect, the authors put forward concrete views and ideas, on the basis of their central suggestion that the issue discussed falls within the context of an emerging precognitive paradigm of criminal law.

Published: March 2020

The Xiphydria annulitibia group is defined to include the following five species from northeastern Asia: X. annulitibia Takeuchi, 1936, from Japan (Hokkaido, Kunashiri Is., Honshu, Shikoku), Korea and Russia (Sakhalin, Primorskij kraj), X. kanba n. sp. from Japan (Hokkaido, Honshu), X. kastsheevi Ermolenko, 1979, from Russia (Primorskij Kraj), X. konishii n. sp. from Japan (Hokkaido, Honshu) and X. melanoptera n. sp. from Japan (Hokkaido). Xiphydria annulitibia is redescribed based on a long series of specimens, including the holotype. Three new species, X. kanba, X. konishii and X. melanoptera, are described and illustrated, and a key is provided for the five species. Xiphydria kastsheevi is excluded from the fauna of Japan. For X. kanba, notes on a rare successful case of branch trapping which yielded 87 adult specimens and observations on the adult emergence from a dead branch and peculiar drumming behavior of the male are given.
