Authors: Jin Liying , Zhao Shengdun , Du Wei , Yang Xuesong , Wang Wensheng , Yang Yuhang
Published: July 2019

In order to optimize the local search efficiency of multi-objective parameters of flux switching permanent motor based on traditional NSGA-II algorithm, an improved NSGA-II (iNSGA-II) algorithm is proposed, with an anti-redundant mutation operator and forward comparison operation designed for quick identification of non-dominated individuals. In the initial stage of the iNSGA-II algorithm, half of the individual populations were randomly generated, while the other half was generated according to feature distribution information. Taking the flux switching permanent motor stator/rotor gap, permanent magnets width, stator tooth width, rotor tooth width and other parameters as optimization variables, the flux switching permanent motor maximum output shaft torque and minimum torque ripple are taken as optimization objectives, thus a multi-objective optimization model is established. Real number coding was adopted for obtaining the Pareto optimal solution of flux switching permanent motor structure parameters. The results showed that the iNSGA-II algorithm is better than the traditional NSGA-II on convergence. A 1.8L TOYOTA PRIUS model was selected as the prototype vehicle. By using the optimized parameters, a joint optimization simulation model was established by calling ADVISOR’s back-office function. The simulation results showed that the entire vehicle’s 100-km acceleration time is under 8 s and the battery’s SOC value maintains at 0.5–0.7 in the entire cycle, implying that the iNSGA-II algorithm optimizes the flux switching permanent motor design and is suitable for the initial design and optimizing calculation of the flux switching permanent motor.
How Much Knowledge Is Too Little? When a Lack of Knowledge Becomes a Barrier to Comprehension
Authors: O’Reilly Tenaha , Wang Zuowei , Sabatini John
Published: July 2019

Have you ever found it difficult to read something because you lack knowledge on the topic? We investigated this phenomenon with a sample of 3,534 high school students who took a background-knowledge test before working on a reading-comprehension test on the topic of ecology. Broken-line regression revealed a knowledge threshold: Below the threshold, the relationship between comprehension and knowledge was weak (β = 0.18), but above the threshold, a strong and positive relation emerged (β = 0.81). Further analyses indicated that certain topically relevant words (e.g., ecosystem, habitat) were more important to know than others when predicting the threshold, and these keywords could be identified using natural-language-processing techniques. Collectively, these results may help identify who is likely to have a problem comprehending information on a specific topic and, to some extent, what knowledge is likely required to comprehend information on that topic.
Paleoenvironmental context of the evolution of the Baodun Culture at Chengdu Plain, Sichuan Province, China
Authors: Huang Ming , Zhu Cheng , Ma Chunmei , He Kunyu , Xu Jiajia
Published: July 2019

The Baodun Culture (4600–3700 a BP) is currently the earliest archeological culture found at the Chengdu Plain in southwestern China. Archeological evidence has shown that the Baodun Culture likely originated from the upper reaches of the Minjiang River, with two possible routes for human migration into the lower Chengdu Plain proposed: (1) At about 5000 a BP, favorable climatic conditions in the upper reaches of the Minjiang stimulated the growth of populations and the development of agriculture in the region. Due to this shift, some groups expanded from the upper Minjiang River to sites in the northern area of the Chengdu Plain, such as the Guiyuanqiao site; (2) during 4800–4300 a BP, a drying event occurred in the upper regions of the river valley causing a reduction in agricultural harvests and the migration of populations into sites – including the Baodun site – from this area of the Minjiang to the southwest piedmont of the Chengdu Plain. A multi-facetted study of the T3321 profile at Baodun site, including pollens, grain size, and geochemistry, demonstrates that after 6000 a BP, the climate of the Chengdu Plain shifted from cool, toward warmer and dryer conditions. However, as the Chengdu Plain is located in an alluvial fan, hydrothermal conditions here are still generally better than those in the upper reaches of Minjiang River. A change in the proportion of Concentricystes seen in the profile T3321 also indicates that after 4700 a BP, the lake and marsh areas associated with the Baodun site further decreased. However, as a result of this reduction, more terrestrial surfaces were exposed, providing favored space for Baodun Cultural groups in the area of the site. Due to such conditions, by about 4600 cal. a BP, people in the upper reaches of the Minjiang River had primarily moved to the southwest piedmont regions of the Chengdu Plain.
Asymmetric Relationship Between Government Revenues and Expenditures in a Developing Economy: Evidence from a Non-linear Model
Authors: Raza Syed Ali , Hassan Syed Zaki , Sharif Arshian
Published: July 2019

Understanding the revenue–expenditure nexus is the core essence of this research in the Pakistani context. This research examines the non-linear relationship between government revenues and government expenditures during 1972–2014. The recently developed non-linear co-integration technique has been used along with the symmetry test. The result shows that the revenues and expenditures have co-integration and provide the evidence in favour of fiscal synchronization hypothesis in the budgetary process. Moreover, the finding also reveals that the relationship between these two fiscal elements is asymmetric and negative changes in revenues and expenditures have a greater impact than the positive ones. Furthermore, another important aspect that was revealed during the study was that the negative shocks in the revenues will lead towards the drastically large increase in the expenditure.
South–South Cooperation in South and East Asia: An Event Study of the China–Pakistan Economic Corridor
Authors: Yeung Wing Him , Pang Yilisha , Aman Asad
Published: July 2019

South–South cooperation has been on the rise in recent years. One of the latest examples is the China–Pakistan Economic Corridor (CPEC) proposed by the Chinese and Pakistani governments in 2013. Using event study methodology, this article examines the impact of events and announcements associated with CPEC on the Pakistan Stock Exchange in Pakistan and the Shanghai Stock Exchange in China. The first key finding of this article is that the initial announcement associated with CPEC had stronger and positive short-term impact on the Pakistan Stock Exchange in comparison with the impact of subsequent CPEC events on the stock market. The second key finding is that the short-term impact of the CPEC initial announcement was stronger on the Pakistan Stock Exchange than on the Shanghai Stock Exchange, possibly due to the substantial difference in the size of the two economies. The empirical results of this article have important implications for investors, corporations and regulators to the Global South.
Health Status of the Elderly Karbis: A Case Study in Morigaon District, Assam
Authors: Sarmah Chandana
Published: July 2019

Health among elderly is an important dimension of quality of life. Health is the outcome of interaction of genetic and environmental factors. In elderly, it is the result of a complex interaction of the physical, social, and psychological aspects of ageing. Health status in this paper has been looked at from the point of view of incidence of diseases, functional ability, nutritional status, and elderly’s self-assessment of health condition.

Data for the study have been collected from 20 villages in Morigaon district of Assam, predominantly inhabited by the Karbi community. Sixty years and above have been taken as the inclusive criterion. The sample consists of 508 elderly male and female Karbis. It is cross-sectional study using both qualitative and quantitative methods. Data have been collected with a structured schedule and nutritional status assessed from body mass index.

Majority of the elderly did not reportedly suffer from any disease. A look into the treatment and management of disease conditions indicates that the elderly persons are mostly not aware of any disease prevalence due to their ignorance. The elderly remain functionally active and this is mainly their criteria of defining health. Of the elderly, 30 percent show low body mass index indicating protein deficiency malnutrition. Self-assessment of health condition as good by most elderly indicates a better psychological health. Functional ability, nutritional status, and self-assessment show an association with age.
The Islamic Subject of Home Cinema of Kerala
Authors: Karinkurayil Mohamed Shafeeq
Published: July 2019

Migration to the Arabian Gulf as the experience of the state of Kerala has mostly been elided in mainstream Malayalam cinema. The digital revolution towards the end of the last century has spurred a local film practice in northern Kerala, usually called ‘Home Cinema’/‘home video’/‘home film’ and so on. Home Cinema of Kerala is locally produced low-quality CD/DVD video productions which are full-length feature films distributed through video shops, stationeries, bookstores and so on. Home Cinema, synonymous in its beginning with the films of Salam Kodiyathur, began as an attempt to oppose what was perceived as the immoral qualities of mainstream cinema, both global and regional. As a counter to the mainstream, Kodiyathur attempted to formulate Islamic cinema but in the idiom of a strand of mainstream Malayalam cinema. This article looks at the constitution of the Islamic subjects of these cinemas as negotiating the figure of the migrant Muslim in the dominant idiom of Malayalam cinema.

Published: July 2019

Salmonella enterica resistance to extended-spectrum cephalosporins (ESC) conferred by cefotaximases ( blaCTX-M) is a growing concern in the United States. Among food-producing animals, poultry are a major reservoir of ESC-resistant Salmonella. A retrospective study was carried out to further characterize 38 ceftiofur-resistant clinical Salmonella enterica isolates obtained from poultry during 2007–2018. Of the isolates tested, 31 displayed resistance to ceftriaxone and harbored blaCMY-2, whereas 7 isolates demonstrated resistance or reduced susceptibility to cefepime in addition to ceftriaxone resistance. These 7 isolates displayed extended-spectrum β-lactamase activity, harbored blaCTX-M-1, and were recovered only from recent poultry diagnostic submissions made in 2011–2018 as opposed to the 31 isolates that were recovered in 2007–2018. Further characterization of the blaCTX-M-1 gene determined that it was located on conjugative IncN/ST1 and IncI1/ST87 plasmids in the isolates from commercial turkeys and broilers, respectively. These plasmids have been responsible for extensive spread of blaCTX-M-1 in livestock, poultry, and humans in Europe. Potential transfer of IncN and IncI1 plasmids and/or nontyphoidal Salmonella carrying these plasmids through the food chain, or by other means to humans, may result in treatment failures. Our study demonstrates the importance of further characterization of ceftiofur-resistant S. enterica isolates detected by veterinary diagnostic laboratories to identify the sources of blaCTX-M-1 and to mitigate the spread of ESC-resistant Salmonella in the poultry production pyramid.
Swine conjunctivitis outbreaks associated with Mycoplasma hyorhinis
Authors: Resende Talita P. , Pieters Maria , Vannucci Fabio A.
Published: July 2019

Conjunctivitis is an uncommon finding in commercial swine herds, and the etiology of the disease is rarely studied. We investigated cases of conjunctivitis in 3 wean-to-finish swine farms. Eye swabs and tissues were obtained from clinically affected pigs (8–22 wk of age), from unaffected pigs in contact with affected pen-mates, and from age-matched pigs from an unaffected herd. Real-time PCR (rtPCR) testing for Mycoplasma hyorhinis demonstrated consistent detection and high bacterial load in samples from affected herds (clinically affected animals and non-clinical pen-mates). Ct values in affected pigs were 18.9–25.3; values were 36.4–38.6 in unaffected pigs from unaffected herds. Additionally, M. hyorhinis was identified within inflamed palpebral conjunctivae by in situ hybridization. The association of rtPCR and in situ detection of M. hyorhinis, along with the lack of detection of other potential pathogens and noninfectious causes, suggests the involvement of M. hyorhinis in the etiology and pathogenesis of the reported swine conjunctivitis.

Published: July 2019

A 9-y-old, zoo-housed, male red panda ( Ailurus fulgens) became progressively lethargic and inappetent over a 1-wk period. Physical examination was unremarkable. A complete blood count showed mild normocytic, normochromic, non-regenerative anemia with the presence of trypomastigote organisms, consistent with a Trypanosoma sp. The organism was confirmed later as Trypanosoma cruzi lineage TcI via PCR and genome sequencing. The panda was initially treated supportively; however, its clinical status within 24 h from presentation deteriorated, and euthanasia was elected. Autopsy showed severe systemic T. cruzi infection with the presence of amastigotes in the heart, brain, peripheral nerves, skeletal muscles, tongue, liver, and testes. We used genome sequencing and serology in identifying the agent.
Fixed Nodes of Transience: Narratives of Homelessness and Emergency Department Use
Authors: McCallum Ross , Medved Maria I. , Hiebert-Murphy Diane , Distasio Jino , Sareen Jitender , Chateau Dan
Published: July 2019

Discourse in popular media, public policy, and academic literature contends that people who are homeless frequently make inappropriate use of hospital emergency department (ED) services. Although researchers have investigated the ED experiences of people who are homeless, no previous studies have examined how this population understands the role of the ED in their health care and in their day-to-day lives. In the present study, 16 individuals participated in semistructured interviews regarding their ED experiences, and narrative analysis was applied to their responses. Within the context of narratives of disempowerment and discrimination, participants viewed the ED in differing ways, but they generally interpreted it as a public, accessible space where they could exert agency. ED narratives were also paradoxical, depicting it as a fixed place for transient care, or a place where they were isolated yet felt a sense of belonging. Implications for policy and practice are discussed.
Construction and Validation of the Interpersonal Influence Tactics Circumplex (IIT-C) Scales
Authors: Bliton Chloe F. , Pincus Aaron L.
Published: July 2019

Assessment of interpersonal dispositions (e.g., traits, problems) commonly employs self- and informant-report measures that conform to the two-dimensional interpersonal circumplex (IPC) model. Here, we adopted the IPC and interpersonal theory as a framework for mapping the universe of content of interpersonal influence. Although there are existing measures of influence tactics used in influence research, this literature is divided among disciplines with varying construct definitions and no unifying theory. Here, we define interpersonal influence as the conscious maneuvering of one’s behavior to engender desired responses from others in interpersonal situations. The current article details the construction and validation of the Interpersonal Influence Tactics Circumplex (IIT-C) Scales in two samples ( Ns = 862, 608). The 64-item IIT-C assesses a comprehensive taxonomy of interpersonal influence tactics conforming to the structure of the IPC. Circumplex structure of the IIT-C was confirmed and replicated. Using the structural summary method for circumplex data, associations with other IPC measures, existing measures of influence, normal personality traits, and pathological personality traits supported the validity of IIT-C scores. The IIT-C assesses a theoretically based and empirically derived set of interpersonal influence tactics and provides a common language for integrating distinct streams of influence research by conforming to the IPC.

Published: July 2019

Little is known about breast cancer in Vietnamese women. Previous studies have reported the frequencies of prognostic factors of breast cancer in this population. The aim of this study was to examine the prognostic factors associated with the survival rates of patients with breast cancer treated at the National Cancer Hospital, Hanoi, Vietnam. We recruited 248 women with operable breast cancer treated with surgery and adjuvant therapy. Tumor tissue samples were stained by many immunohistochemical approaches and analyzed for estrogen receptor, progesterone receptor, and HER2 gene amplification status. A Cox model was used to determine the relationship between survival and the prognostic factors. The disease-free survival rate, overall survival rate, and cancer-specific survival rate were 75.8%, 80.6%, and 86.4%, respectively, at 5 years and 62.3%, 68.1%, and 78.9%, respectively, at 10 years. The lung was the most common metastatic site. Women with factors associated with a poor prognosis (eg, advanced clinical stage, high tumor grade, progesterone receptor [PR] negativity, HER2 amplification) had significantly lower survival rates. Patients with PR-negative breast cancer had significantly worse survival rates compared to those who were PR positive, according to multivariate analysis (hazard ratio = 1.77, 95% confidence interval: 1.01-3.11, P = .045); however, there was only a statistically significant difference in postmenopausal patients. The PR was a prognostic factor in postmenopausal women with breast cancer, but not in premenopausal women.

Authors: Brown Margaret J. , Adams Susie M. , Vanderhoef Dawn , Schipani Rosanne , Taylor Ashley
Published: July 2019

INTRODUCTION: Measurement-based care (MBC) uses standardized measurement to systematically monitor treatment response over time. Although MBC is underutilized in mental health settings, primary care–mental health integration (PC-MHI) settings are expected to provide MBC. This article describes a quality improvement (QI) process to increase Patient Health Questionnaire-9 (PHQ9) utilization within a PC-MHI setting. AIMS: Pre-intervention, rates of baseline and follow-up PHQ9 administration for veterans with a depressive disorder were 76% and 35%, respectively. This article describes a QI process to increase PHQ9 utilization rates within a PC-MHI setting, with the goal to improve provider PHQ9 utilization rates at baseline and within 4-week follow-up to 90%. METHOD: An educational intervention and weekly motivational enhancement sessions were implemented in 2017. Chart review data compared PHQ9 utilization rates from fall 2016 and 2017. RESULTS: Following intervention, provider PHQ9 utilization rates increased to 98% and 88% at baseline and follow-up. CONCLUSIONS: These findings demonstrate that a brief education-based intervention can increase clinician use of MBC within a PC-MHI setting. Meaningful use of MBC to inform treatment was not evaluated in this QI project and is an area for future investigation.

This case report presents a rare association of a complete aniridia with lenticular and choroidal coloboma. An 8-year-old female patient was referred to our glaucoma clinic with aniridia, nystagmus and bilateral corneal opacity with right eye being phthisical. Ultrasonography of the phthisical eye revealed the presence of an old closed funnel retinal detachment. Further examination under anaesthesia revealed lens coloboma in the inferonasal quadrant and presence of a choroidal coloboma in the left eye. The intraocular pressure was 28 mmHg with a central corneal thickness of 693 µm. A macula sparing laser barrage around the colobomatous area was done in the left eye and topical ocular hypotensives were started.
Digital Communication Tools for Fostering Career Advancement and Sustaining Interpersonal Relationships
Authors: González Ramos Ana M
Published: July 2019

Communication technologies have become essential for connecting people from different countries searching for employment and challenging careers. Highly skilled migrants keep in touch with family members through communication technologies, which have engendered intimacy based on long distance relationships. This work explores the use of communication technologies among the highly skilled, focusing both on professional and personal relationships, with an emphasis on the gender perspective. Throughout their discourses, technology appears as a fundamental tool for managing professional careers from a distance. Findings reveal both persisting patterns of traditional relationships managed by technology and the emergence of new habits and codes for enhancing personal connections. A gender approach illuminates few differences in the professional environment, in which information and communication technologies appear as neutral tools. However, in the personal sphere, although traditional family roles are being reshaped through technology, they are also partially reinforced.
Designer notoriety: What the Lubitz case tells us about the accumulation of attention capital in celebrity culture
Authors: Rojek Chris
Published: July 2019

This article introduces the concept of designer notoriety to refer to calculated attempts to derail aspects of normative order so as to garner media attention. The objective is for otherwise unexceptional people to gain celebrity. The case of the alleged sabotage of Germanwings Airbus A320 Flight, by the co-pilot, Andreas Lubitz, in 2015, is used as a case study. Drawing on the methods of content analysis from various media sources and historical sociology, the article examines the media claim that Lubitz sought celebrity and planned the crash as a means to acquire media interest. Public receptivity to the notion of designer notoriety is investigated. It is related to three key concepts: ‘the demotic turn’, ‘mediatization’ and the ‘world historic event’. The application of each concept to designer notoriety is set out and justified. The article ends by expanding the Lubitz case to refer to other examples of designer notoriety.
Exploring the impact of external shading system on cognitive task performance, alertness and visual comfort in a daylit workplace environment
Authors: Leccese F , Salvadori G , Öner M , Kazanasmaz T
Published: July 2019

The authors examined the effect of external shading system on cognitive performance, alertness and visual comfort of visual display terminal (VDT) users under two realistic office lighting settings in this study. Daylight was the source of illumination being considered as the most significant and preferred one. A total of 26 participants performed visual and cognitive demanding tasks as well as providing subjective alertness, performance and visual evaluations in a full-scale mock-up VDT workstation. Two trials (with and without shading system) were executed during one experimental session. Results revealed that the use of a shading system improves the performance of a user on colour-naming task requiring sustained attention, while no differential effects were observed on tasks involving other cognitive skills such as search velocity and vigilance. Within-subject performance differences were more pronounced during morning hours. Higher performance was reported in some cognitive tests when the subjective sensation of visual discomfort was lower.
Antonio Gramsci on religion
Authors: Forlenza Rosario
Published: July 2019

This article provides an introduction to Antonio Gramsci’s understanding and analysis of religion. It shows that Gramsci’s conceptual constellation and key terms – from hegemony to organic intellectuals, from moral and intellectual reform to common sense – were formulated precisely in his critique to religion, and specifically to Catholicism in Italy. Rejecting the determinism and reductionism of orthodox Marxism, Gramsci saw religion as an active mode of experiencing social and historical reality, and came to conceptualize Marxism (the philosophy of praxis) as a new secular religion. The article demonstrates how Gramsci subtly and deftly problematized the relationship between religion, power, and politics in society. It will in particular foreground his astute reading of religion in practices and in common sense. Gramsci’s views on religion, this article argues, offer insightful theoretical tools that could be of considerable benefit for scholars (sociologists, anthropologists, and historians) examining religious phenomena in a global post-modern world.
Examination of attention, executive function, and memory as predictors of mortality risk in adults with systolic heart failure
Authors: Gathright Emily C , Dolansky Mary A , Gunstad John , Josephson Richard A , Moore Shirley M , Hughes Joel W
Published: July 2019

Background:

The prevalence and impact of cognitive impairment in heart failure is increasingly recognized. Converging evidence points to global cognitive function as predictive of prognosis in adults with heart failure when assessed with screening tools. Additional work is needed to understand which domains of cognitive function are most relevant for prognosis.

Aims:

The present study sought to examine associations between domains of cognitive function and mortality risk in adults with heart failure.

Methods:

In the present prospective, observational cohort study, global cognitive function, attention, executive function, and memory were assessed by means of a comprehensive neuropsychogical battery in adults with systolic heart failure. Mortality data were obtained from the National Death Index (median follow-up 2.95 years). Relationships among each cognitive domain and mortality were assessed with Cox regression. Covariates included age, sex, heart failure severity, comorbidity and depressive symptoms.

Results:

Participants were 325 patients with systolic heart failure with a mean age of 68.6 years (59% men, 73% Caucasian). Following covariate adjustment, better global cognitive function, attention, and executive function were related to decreased mortality risk.

Conclusions:

Future research is needed to clarify the underlying mechanisms of the association between cognitive impairment and mortality.
A visual-physiology multimodal system for detecting outlier behavior of participants in a reality TV show
Authors: Kang Shinjin , Kim Donggyun , Kim Youngbin
Published: July 2019

This study proposes an outlier detection system based on the visual-physiology multimodal data system for a Korean reality TV show, “Perfect on Paper.” The goal of this system is to provide the program production team and the master of ceremonies with real-time facial expressions and bio-signal analysis results of program participants. Using this information, the program production team and master of ceremonies can easily identify the participants with unusual behavior. We propose an insole-type hardware that measures the wearer’s skin conductivity, temperature, and motion. We also suggest a dynamic time warp-based clustering algorithm for the outlier and micro-expression detection technique. The system was developed starting from the program planning phase through a 6-month period in collaboration with the production team. The developed system analyzed the biometric information and facial expressions of 88 participants in 11 episodes and provided rapid feedback to the production team at the shooting spot in real time. Finally, we present a case where a visual-physiology multimodal system can be useful for a real TV broadcasting production.
An efficient outsourced attribute-based encryption scheme in the device-to-device mobile network
Authors: Wang Huawei , Li Ye , Jiao Yingnan , Jin Zhengping
Published: July 2019

Device-to-device communication is considered as one of the hopeful technologies for proximal communication, which plays a vital role in the wireless systems and 5G cellular networks. The outsourced attribute-based encryption scheme is convinced to be very suitable for secure device-to-device communication since it allows not only fine-grained sharing of encrypted data but also achieves high efficiency in the decryption of general attribute-based encryption schemes. However, almost all existing outsourced attribute-based encryption schemes can hardly be applied directly in the device-to-device communication because many heavy computation operations, such as pairing and modular exponentiations, cannot be taken on the mobile devices in the device-to-device network. In this article, we propose a concept of outsourcing threshold decryption for attribute-based encryption and design a new efficient outsourcing threshold decryption scheme for ciphertext-policy attribute-based encryption. In our definition of outsourcing threshold decryption, the decryption, which is a computationally expensive operation, is outsourced to multiple semi-trusted and lightweight computing devices determined by an access structure and can be jointly taken by these devices. Our scheme supports proxy re-encryption which enables the decryption delegation. Finally, security and efficiency analyses of our proposed method indicate that our proposal guarantees strong security against chosen plaintext attacks and requires less outsourced computation and communication cost than the existing outsourced attribute-based encryption schemes.
One Year of #GamerGate: The Shared Twitter Link as Emblem of Masculinist Gamer Identity
Authors: Dowling David O. , Goetz Christopher , Lathrop Daniel
Published: July 2019

Since the #GamerGate controversy erupted in 2014, anti-feminist gamers continue to lash out at feminists and supporters of progressive and inclusive gaming content. A key strategy in this discourse is the sharing of content via links on Twitter, which accompany messages positioning the sender on either side of the debate. Through qualitative analysis of a data set drawn from 1,311 tweets from 2016 to 2017, we argue that tweeted links are a salient tool for signaling affiliation with gaming communities. For anti-feminist gamers, the tweeted link defines masculinist gamer identity and constructs social boundaries against the increasing diversification of video game culture reflected in higher overall rates of feminist tweets. Links can be construed as revelatory of boundary work and thus can help shed insight on the extent to which #GamerGate discourse was intended to defend gaming culture as an exclusively masculine space.
Nonsteroidal anti-inflammatory drug use is a risk factor for early Type II endoleak after endovascular abdominal aortic repair

Published: July 2019

Objectives

Type II endoleak is a problem after endovascular abdominal aneurysm repair. Preoperative risk factors for Type II endoleak include anatomical factors in the lumbar artery and inferior mesenteric artery; however, preventable postoperative risk factors are unknown. Postimplantation syndrome is associated with lower incidence of Type II endoleak. Therefore, we focused on inflammation, and our aim was to investigate nonsteroidal anti-inflammatory drugs as a postoperative risk factor for Type II endoleak.

Methods

This was a retrospective study of patients with aortic aneurysm who underwent endovascular aneurism repair at the Department of Cardiovascular Surgery, Beppu Medical Center, Oita, Japan, from January 2011 to August 2018. Clinical characteristics were retrieved from patients’ medical records and included age, sex, body mass index, smoking history, comorbidities, treatment devices, medications, and perioperative information, including postimplantation syndrome. Postimplantation syndrome was defined as body temperature >38.5°C with 12,000/dL white blood cells or >10.0 mg/dL C-reactive protein. The primary outcome was the presence or absence of Type II endoleak assessed on the first postoperative enhanced computed tomography scan. Risk factors for Type II endoleak were assessed. Results and conclusions: Of the eligible 84 patients, 20 (24%) had Type II endoleak identified in the first enhanced computed tomographic scans after endovascular aneurism repair. Nonsteroidal anti-inflammatory drug use (odds ratio (OR): 21.2; 95% confidence interval (95% CI): 1.5–308.4; P = 0.026), cerebrovascular disease (OR: 7.27; 95% CI: 1.06–49.99; P = 0.044), and body mass index <22 kg/m2 (OR: 17.3; 95% CI: 2.1–141.8; P = 0.008) were independent risk factors for Type II endoleak after endovascular aneurism repair. Comparing the rate of Type II endoleak among patients who did not receive nonsteroidal anti-inflammatory drugs within 24 h after endovascular aneurism repair, patients who first used nonsteroidal anti-inflammatory drugs 12–24 h after endovascular aneurism repair, and those who received nonsteroidal anti-inflammatory drugs within 12 h after endovascular aneurism repair, we found a significant difference among the groups (4%, 18%, 45%, respectively; P = 0.001). Nonsteroidal anti-inflammatory drug use within 24 h after endovascular aneurism repair is a risk factor for Type II endoleak. We should know nonsteroidal anti-inflammatory drugs within 24 h after endovascular aneurism repair can be a risk of Type II endoleak.
Role of Toll-like receptor 4 signaling in mast cell-mediated migraine pain pathway

Published: July 2019

Degranulation of meningeal mast cells leading to the sensitization of trigeminal vascular afferent processing is believed to be one of the mechanisms underlying the migraine pain pathway. Recent work suggests that Toll-like receptor 4 (TLR4) may be involved in signaling states of central sensitization. Using a murine model of light aversion produced by compound 48/80 (2 mg/kg, intraperitoneal) mast cell degranulation, employed as a surrogate marker for photophobia observed in migraineurs, we examined the role of TLR4 in migraine-like behavior and neuronal activation. Using a two-chambered light/dark box, we found that compound 48/80 administration in male and female C57Bl/6 mice produced light aversion lasting up to 2 h, and that pre-treatment with sumatriptan (1 mg/kg, i.p.) reliably prevented this effect. Genetic deletion and pharmacological blockade of TLR4 with TAK-242 (3 mg/kg, i.p.) reversed the light aversive effects of compound 48/80 in males but not in females. Assessing the downstream signaling pathway in mutant mice, we found that the TLR4-mediated, light aversion was dependent upon myeloid differentiation primary response gene 88 but not Toll-interleukin-1 receptor domain-containing adapter-inducing interferon-β signaling. In separate groups, male mice sacrificed at 10 min following compound 48/80 revealed a significant increase in the incidence of evoked p-extracellular signal–regulated kinases (+) neurons in the nucleus caudalis of wild type but not Tlr4−/− mice or in mice pre-treated with sumatriptan. This study thus provides the first evidence for involvement of TLR4 signaling through MyD88 in initiating and maintaining migraine-like behavior and nucleus caudalis neuronal activation in the mouse.

Published: July 2019

Collagen from fish scale waste is currently being studied as a promising biological material to replace collagen from animals because of advantages such as safe, fat-free, not suffering from communicable diseases, and easy absorption in human body solutions. Finding the suitable process of extracting fish scale collagen is necessary because extracting collagen from fish scales by chemical methods often requires a long time. Therefore, in this paper, some bases and acids at different concentrations were chosen to find the most suitable condition for extracting fish scale collagen from the wastage of different scale fishes belonging to the familiar Cyprinus genus. The characterizations of the extracted collagen including structure, morphology, element composition, relative molecular weight, amino acid composition, denaturation temperature, crystal structure, and thermal stability were investigated. In addition, the amino acid sequence of the extracted collagen was also determined and compared with the National Center for Biotechnology Information protein database.
Comparative Effectiveness of Alternative Dosing Regimens of Hyaluronic Acid Injections for Knee Osteoarthritis: A Systematic Review
Authors: McElheny Kathryn , Toresdahl Brett , Ling Daphne , Mages Keith , Asif Irfan
Published: July 2019

Context:

Viscosupplementation is widely used for management of knee osteoarthritis. Many formulations of hyaluronic acid (HA) are available, ranging from a single injection to a series of up to 5 injections per treatment.

Objective:

To compare efficacy between single and multiple HA injection formulations.

Data Sources:

MEDLINE, EMBASE, Cochrane, Web of Science, Scopus databases were all searched.

Study Selection:

Full-text prospective randomized and nonrandomized controlled human trials, cohort studies, and cost-effectiveness evaluations in the English language comparing different injection regimens of viscosupplementation were included.

Study Design:

Systematic review.

Level of Evidence:

Level 1.

Data Extraction:

Data were collected using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Four databases were searched by a librarian and the principal investigator, identifying 6196 articles for screening.

Results:

Eleven studies met the inclusion criteria. Of the studies comparing single- with multiple-injection formulations of HA for treatment of knee osteoarthritis, there was no consistent difference in patient-reported outcomes. Furthermore, 5-injection formulations do not appear to be superior to 3-injection formulations.

Conclusion:

There are limited head-to-head trials comparing viscosupplementation formulations that differ based on number of injections, and in particular, there is a paucity of trials evaluating single-injection formulations. Based on the currently available data, there appears to be similar efficacy with the possibility for greater cost-effectiveness and less patient inconvenience with single-injection formulations.
Illusory Oscillation of the Central Rotation Axis
Authors: Nakajima Yutaka , Kakuda Shohei , Satoh Shunji
Published: July 2019

In this study, we report a novel visual illusion for rotational motion, in which the central rotation axis of a partially invisible (apparent) square is perceived as exhibiting oscillatory rotation. To investigate the cause of this illusion, we measured the central position of a static apparent shape using an adjustment method (Experiment 1) and manipulated the speed of the rotating apparent square to test whether the illusion could be cancelled out by counteracting rotation using a constant method (Experiment 2). The results revealed that the perceived central position of a static apparent shape was shifted toward the outside. The shifted position depended on the orientation of the stimulus, and its position was arranged as if it was moving in a circular trajectory. In addition, the cancellation technique using counteracting rotation was successful, and cancellation of faster rotation required a greater radius of counteracting rotation. These results indicated that the illusion is induced by an interaction between illusory shifts of the central position of the static shape and the summation of motion vectors or motion momentum (e.g., centrifugal force) derived from shape representation by perceptual completion.

To investigate the effects of total flavonoids from Oxytropis falcata Bunge on the inflammatory signaling pathway suppressor of cytokine signaling (SOCS)/Janus kinase (JAK)/signal transducer and activator of transcription (STAT) in diabetic nephropathy KK-Ay mice. KK-Ay mice were used to establish a diabetic nephropathy model. The general condition of the mice treated with different concentrations of total flavonoids from O. falcata was monitored, respectively. Body weight, blood glucose, 24-h urinary albumin (UAlb), serum creatinine (Cre), blood urea nitrogen (BUN), and uric acid (UA) levels were measured at different time points. Hematoxylin and eosin staining quantitative reverse transcription-polymerase chain reaction and western blotting were used to detect changes in renal tissues and glomerular mesangial cells. Four weeks after model establishment, body weight, blood glucose, and 24 h UAlb significantly increased in KK-Ay mice compared with that in control C57BL/6j mice ( P < 0.05). Compared with non-treated model mice, mice treated with total flavonoids from O. falcata for 4 weeks had significantly decreased serum Cre, BUN, and UA; monocyte chemoattractant protein-1(MCP-1), nuclear factor(NF)-κB, interleukin(IL)-6, and transforming growth factor(TGF)-β1, JAK 1, STAT 3 and STAT 4 mRNA levels; and p-JAK2 and p-STAT1 protein levels and significantly increased SOCS-1 and SOCS-3 protein levels in the kidneys. The treatment effects were dose-dependent and same to in vitro. Our results reflected that total flavonoids from O. falcata relieved renal tissue inflammation in diabetic mice by reducing blood glucose levels and inhibiting JAK/STAT signaling, thereby protecting against the development of diabetic nephropathy.

Global health policies are promoting increased vegetable intake across all socioeconomic levels. However, the association between healthy vegetable intake and perception of the food environment has not been well investigated. Consequently, this study aimed to examine the association between vegetable intake and perceptions of neighborhood food environments. Participants were 3,137 Japanese adults (1,580 men, 1,557 women), aged 30 to 59 years, who completed an Internet-based survey. Self-report data were collected: vegetable intake, perceptions of food environment, household income, and demographic variables. We found that positive perceptions of the food environment (e.g., reasonable prices for foods and good social capital of food) predicted healthy vegetable intake in all household income groups. Therefore, supporters should take note of perceptions of the food environments—the findings suggest that the food environment can be altered via changing perceptions surrounding costs.
Tailoring Narration for Distinct Audiences in Emerging Adulthood

Published: July 2019

The development of narrative identity is a critical task for emerging adults—one shaped by parents and peers. However, how diverse audiences might jointly shape narrative identity remains underexamined. The present study addresses this gap, examining how emerging adults perceive diverse audiences for their narratives and tailor those narratives. In Study 1, emerging adults ( N = 112 and 106) rated peer audiences as more frequent, comfortable, agreeable, and less challenging audiences compared to mothers and fathers. In Study 2, participants ( N = 106 participants; n = 1272 narratives) responded to four narrative prompts: first, the standard prompt with no audience specified and then edited those narratives (if desired) for mothers and for friends. Broadly, relative to friends, mothers elicited more positive, but also more edited, narratives. These findings illustrate the social-relational dynamics of narrative identity construction in emerging adulthood, as well as implications for narrative autonomy and narrative intimacy.

Published: July 2019

Haemophilus influenzae is serologically classified into two main categories based on the presence or absence of the polysaccharide capsule. Strains that possess polysaccharide capsules are identified as typeable Haemophilus influenzae, whereas strains that do not have capsules are identified as non-typeable Haemophilus influenza. Only on very rare occasions, Haemophilus influenzae affects adult joints, and almost 95% of cases have been identified as type b serotypes. Coexistence of gouty and septic arthritis is rare but has been reported. We herein report a case of polyarticular septic arthritis caused by non-typeable Haemophilus influenzae in an adult with concomitant new-onset gouty arthritis. The case was successfully treated with surgical debridement and a 4-week course of ceftriaxone.

Background. Despite multiple guidelines recommending admission, there is significant variation among emergency departments (EDs) regarding disposition of neonates presenting with fever. We performed a statewide epidemiologic analysis to identify characteristics that may influence patient disposition in such cases within North Carolina. Methods. This study is a retrospective cohort study of infants 1 to 28 days old with a diagnosis of fever presenting to North Carolina EDs from October 1, 2010, to September 30, 2015, using data from the NC DETECT (North Carolina Disease Event Tracking and Epidemiologic Collection Tool) database. We analyzed various patient epidemiology characteristics and their associations with patients being admitted or discharged from the emergency room setting. Results. Of 2745 unique patient visits for neonatal fever, 1173 (42.7%) were discharged from the ED, while 1572 (57.3%) were either admitted or transferred for presumed admission. Age, sex, region within North Carolina, and the presence of a pediatric service did not significantly influence disposition. An abnormal documented ED temperature was associated with higher likelihood of admission ( P < .01). The size of the hospital was also found to be significant when comparing large with small hospitals ( P < .01). Government-funded insurance was associated with lower likelihood of admission ( P < .01). Conclusions. A high number of neonates diagnosed with fever were discharged home, inconsistent with current recommendations. An association with a government-funded insurance represents a possible health care disparity. Further studies are warranted to further understand these variations in practice.
