Published: April 2019

Abstract
A novel adsorbent, composed of cross-linked de-esterified pectin microspheres, was prepared via cross-linking with Ca(II) and modification by de-esterified pectin, low-methoxyl pectin (LMP) and pectic acid (PA). Fourier transform infrared (FTIR), energy dispersive spectrometry (EDS), scanning electron microscopy (SEM) and atomic absorption spectroscopy (AAS) were applied too, exhibiting a successful fabrication, good adsorption ability, and well-defined surface microstructure beneficial to Pb(II) adsorption. The adsorption ability of pectin microspheres (PMs), low-methoxyl pectin microspheres (LMPMs) and pectic acid microspheres (PAMs) for Pb(II) in aqueous solution were explored. The maximum adsorption capacity of PMs, LMPMs and PAMs was 127 mg·g−1, 292 mg·g−1 and 325 mg·g−1 at pH 5.0 respectively, indicating a great improvement of LMPMs and PAMs in the adsorption ability for Pb(II) compared with PMs. Furthermore, the adsorption mechanism was proposed. The experimental data were well fitted with pseudo-second-order kinetic and Langmuir isotherm models. Five-cycle reusability tests demonstrated that microspheres could be used repeatedly. All the results confirmed that LMPMs and PAMs, which presented outstanding adsorption capability and reusability, could be a good candidate for wastewater purification.

Published: April 2019

Background
High rates of mental illness, stress, and suicidality among teens constitute a major public health concern in the United States. However, treatment rates remain low, partially because of barriers that could be mitigated with tech-based telemental health (TMH) resources, separate from or in addition to traditional care.

Objective
This study aimed to analyze TMH resource usage by high school students to establish current user characteristics and provide a framework for future development.

Methods
A total of 2789 students were surveyed regarding demographics, recent anxiety and depression symptoms, suicidality, and stress; people with whom they could openly and honestly discuss stress or problems, and prior TMH use. Logistic regression models and a general linear model were used to test relationships between variables.

Results
Overall, 30.58% (853/2789) and 22.91% (639/2789) of students reported moderate to severe anxiety and depression symptoms, respectively, in the past 2 weeks; 16.24% (414/2550) had seriously considered suicide in the past year, consistent with national averages. Meanwhile, 16.03% (447/2789) of students had previously used at least 1 of 4 types of TMH resources (ie, self-help, anonymous chat, online counselor, or crisis text line). Teens reporting depression symptoms, higher stress, or suicidality were less likely to talk to a parent about stress or problems and more likely to tell no one. Suicidality was related to the use of all 4 types of TMH resources. Depression symptoms were related to the use of anonymous chat and crisis text line, and those with higher stress were more likely to have used an online counselor. Those reporting anxiety symptoms were less likely to have no one to talk to and more likely to have used a self-help resource.

Conclusions
Youth struggling with mental health symptoms, some of whom lack real-life confidants, are using existing TMH support, with resource preferences related to symptoms. Future research should consider these preferences and assist in the creation of specialized, evidence-based TMH resources.

OBJECTIVE
To assess treatment satisfaction and the effectiveness of a flash glucose monitoring (FGM) system in patients with type 2 diabetes using insulin.

RESEARCH DESIGN AND METHODS
A total of 101 patients with type 2 diabetes on multiple daily insulin injections (MDI) for at least 1 year were assigned randomly to the FGM intervention (n = 53) or the standard care (control) group (n = 48) and followed for 10 weeks. Both groups were instructed to adjust their insulin doses in face-to-face and telephone visits. Satisfaction with treatment, quality of life, comfort using FGM, HbA1c, and frequency of hypoglycemic events were evaluated.

RESULTS
The intervention group found treatment significantly more flexible (P = 0.019) and would recommend it to their counterparts (P = 0.023). Satisfaction using the FGM system was high. The changes in HbA1c were –0.82% (9 mmol/mol) vs. –0.33% (3.6 mmol/mol) in the intervention and control group, respectively (P = 0.005); in nonprespecified post hoc analysis, 68.6% of the patients in the intervention group had their HbA1c reduced by ≥0.5% (5.5 mmol/mol) compared with 30.2% in the control group (P &lt; 0.001), and 39.2% had their HbA1c reduced by ≥1.0% (10.9 mmol/mol) vs. 18.6% in the control group (P = 0.0023) without an increased frequency of hypoglycemia.

CONCLUSIONS
FGM tends to improve treatment satisfaction and may lead to amelioration of glycemic control in patients with type 2 diabetes on MDI without increasing the frequency of hypoglycemia.

Published: April 2019

OBJECTIVE
Altered plasma amino acid levels have been implicated as markers of risk for incident type 2 diabetes; however, amino acids are also related to established diabetes risk factors. Therefore, potential for confounding and the impact from competing risks require evaluation.

RESEARCH DESIGN AND METHODS
We prospectively followed 2,519 individuals with coronary artery disease but without diabetes. Mixed Gaussian modeling identified potential for confounding. Confounding, defined as a change in effect estimate (≥10%), was investigated by comparing amino acid–incident diabetes risk in a Cox model containing age and sex with that in models adjusted for potential confounders (BMI, estimated glomerular filtration rate, HDL cholesterol, triacylglycerol, C-reactive protein), which were further adjusted for plasma glucose, competing risks, and multiple comparisons (false discovery rate = 0.05, Benjamini-Hochberg method). Finally, component-wise likelihood-based boosting analysis including amino acids and confounders was performed and adjusted for competing risks in order to identify an optimal submodel for predicting incident diabetes.

RESULTS
The mean age of the source population was 61.9 years; 72% were men. During a median follow-up of 10.3 years, 267 incident cases of diabetes were identified. In age- and sex-adjusted models, several amino acids, including the branched-chain amino acids, significantly predicted incident diabetes. Adjustment for confounders, however, attenuated associations. Further adjustment for glucose and multiple comparisons rendered only arginine significant (hazard ratio/1 SD 1.21 [95% CI 1.07–1.37]). The optimal submodel included arginine and asparagine.

CONCLUSIONS
Adjustment for relevant clinical factors attenuated the amino acid–incident diabetes risk. Although these findings do not preclude the potential pathogenic role of other amino acids, they suggest that plasma arginine is independently associated with incident diabetes. Both arginine and asparagine were identified in an optimal model for predicting new-onset type 2 diabetes.

Abstract

OBJECTIVE
To investigate the reasons for evaluation on an emergency basis of and short-term outcomes for chickens from backyard flocks.

DESIGN
Retrospective case series.

ANIMALS
78 chickens.

PROCEDURES
For chickens evaluated on an emergency basis at a New England veterinary teaching hospital in January 2014 through March 2017, information including age, sex, flock size, primary medical problem, final diagnosis, and immediate outcome was obtained from electronic medical records. Primary medical problems were classified as abnormal droppings, crop or gastrointestinal tract disease, lameness, neurologic disease, nonspecific signs (ie, undefined illness), respiratory tract disease, reproductive tract disease, and trauma.

RESULTS
78 chickens were evaluated on an emergency basis, of which 71 were females from small flocks. The median age of the chickens was 1 year (range, 0.1 to 7 years). The most common problem was trauma (n = 25), followed by nonspecific signs (11) and reproductive tract disease (10); 18 birds had neurologic disease (6), lameness (6), or gastrointestinal tract disease (6). Five birds had respiratory tract disease, and 3 had abnormal droppings. Six birds were brought to the emergency service for euthanasia only. Trauma, reproductive tract disease, and signs of Marek disease were most frequently identified in birds that were fully evaluated. Thirty-five (45%) chickens were discharged from the hospital.

CONCLUSIONS AND CLINICAL RELEVANCE
Results indicated that backyard flock chickens were evaluated on an emergency basis most commonly because of trauma and reproductive tract disease. Although approximately half of the evaluated chickens were euthanized, the remainder were discharged from the hospital and required medical management. (J Am Vet Med Assoc 2019;254:1196–1203)
Digitalized Interactive Platforms: Turning Goods and Services into Retail Co-Creation Experiences
Authors: Ramaswamy Venkat , Ozcan Kerimcan 
Published: April 2019

Abstract
With the rise of digital technologies, retailing has become a field of value co-creation. Rather than selling readymade products and services, retailers now offer means for creating value together with their customers through manifold interactions. To enable co-creation, they need to develop digital interactive platforms (DIPs) around retail-related activities. Typically, individuals engage with a retail DIP offering in their particular contexts of interactions with apps or similar components. By delving deeper into the nature of the individual interactions, hidden and untapped sources of value can be revealed. Shoppers get more engaged, and retail managers gain more insights and can design ecosystems that allow a more effective creation of “all-win more” outcomes in more profitable ways. To be successful, retailers need to incorporate a broader view of value creation into their operations. They will be successful with hybrid-delivery systems in which consumers can use a range of interface technologies across multiple channels. Being able to interact with informational content, human actors, and technical resources at different stages of the decision making and shopping process will enable rewarding shopping experiences for customers and retailers alike.
E-Commerce in a Physical Store: Which Retailing Technologies Add Real Value?
Authors: Linzbach Peter , Inman J. Jeffrey , Nikolova Hristina 
Published: April 2019

Abstract
To remain competitive in a connected world, offline retailers have responded with integrating digital in-store technologies into their physical servicescapes. Often, the introduction of multichannel connecting services like click & collect or order from or return to store are first steps.
Shopper-facing advanced technologies can be key to creating a different physical shopping experience for consumers and delivering benefits to retailers such as improved traffic, conversion and baskets or streamlined operational cost. In general, consumers consider retailing technologies as useful. However, shoppers assess the fairness of the exchange about procedures, outcome and treatment and the value of the technology they receive compared to what the retailer gets. Also, satisfaction, trust and privacy concerns are relevant for customers. Retail managers need to ensure the functionality and safety of their application and take consumer concerns seriously. Also, they need to address privacy concerns and build trust, if they want proximity marketing to deliver on its promise of increasing basket size or attracting new shoppers.
Metodologias de pesquisa em jornalismo participativo no Brasil
Authors: Holanda André , Quadros Claudia , Silva Jan Alyne Barbosa , Palacios Marcos 
Published: April 2019

A dimensão participativa do jornalismo pode ser caracterizada, de maneira ampla, pela criação e implementação de mecanismos que possibilitem envolver o público em diferentes etapas dos processos de coleta, criação, análise e distribuição de notícias. A forma de compartilhar informações tem se mostrado bastante variável em diferentes sistemas de comunicação participativos, como fóruns, blogs e sites de tipo open source. Em maior ou menor medida, o jornalismo se transforma à medida que o fenômeno colaborativo cresce. Dan Gillmor (2004) sugere que os leitores ao assumirem o papel de repórteres modificam a sua interação com a notícia: da simples leitura passam à conversação. Shane Bowman e Chris Willis (2003) defendem que a participação ativa dos cidadãos possibilita a oferta de informações mais confiáveis, independentes e relevantes. O modo participativo de fazer jornalismo tem despertado o interesse de diversos pesquisadores em todo o mundo, como Deuze (2003, 2005, 2006), Gillmor (2004), (2006), Axel Bruns (2005), Stephen D. Reese, Lou Rutigliano, Kideuk Hyun e Jaekwan Jeong (2007), dentre outros.

The Impact of Network Centralization on Relational Capital
Authors: Osman Lokhman Hakim Bin 
Published: April 2019

With an increasing degree of connections among firms forming network of economic activities, it is timely to assess the potential of these upon embedded firms. This article presents empirical evidence to that end. It distinguishes between decentralized and centralized network structure that illustrate the difficulties encountered in managing an inter-firm network structure. Although considerable studies has been performed in network issues affecting firms performance, very few research analyse the complicating attributes of a centralized network structure on its effects on firms performance. Thus this article described different attributes of the centralized network and its effects on firms’ relational capital outcomes. Using social network analysis methodology this study found that certain structural position occupied by firms in network impacts on its relational capital outcome. This study is significant as it’s contributed to prudent management of resources in managing complex network structure. Future research is also discussed.

Revisiting communicative competence in the teaching and assessment of language for specific purposes
Authors: Whyte Shona 
Published: April 2019

The term communicative competence captures the notion that the ability to use language in interaction requires not just control of linguistic form but also awareness of rules of use in different contexts (Hymes 1972). Communicative competence is a slippery term: different actors in second language (L2) research, education, and assessment interpret the term in a variety of ways and use it for a range of purposes, perhaps particularly in the field of languages for specific purposes (LSP). This is unfortunate because it is a key concept in LSP, as in applied linguistics more generally. Communicative competence can be considered to be the target of second language acquisition, a main goal of second or foreign language teaching and learning, or the object language testers seek to measure via performance tests. In addition, current interpretations of communicative competence may be somewhat questionable adaptations of Hymes’ concept, modified and often simplified to reflect current approaches in both formal and functional linguistics, and to respond to practical concerns in language teaching and testing. This paper seeks to re-examine communicative competence from three perspectives – L2 research, teaching, and testing – highlighting problems in terms of theory and practice with respect to LSP. Drawing on recent research on indigenous assessment criteria, the paper concludes with a revised model of communicative competence for LSP offering a richer interpretation closer to the original concept and to current concerns in the field.
Mucormicosis
Authors: Quiroz Nathalie , Villanueva Janeth Del Pilar , Lozano Edgar Andrés 
Published: April 2019

La mucormicosis es una micosis oportunista y poco frecuente, producida por hongos Zygomicetos del orden Mucorales, asociada con inmunosupresión y de curso agresivo y mortal. Puede dividirse en varios tipos, según el lugar de infección, en rinocerebral (por extensión desde la rinofaringe o por diseminación hematógena), cutánea (más habitualmente en pacientes con diabetes mellitus descompensada, leucemia o cáncer) y pulmonar, entre otras. Generalmente, se adquiere por vía respiratoria ya que las esporas de los hongos se encuentran en el ambiente, aunque en las formas cutáneas primarias, la infección se adquiere por solución de continuidad. El diagnóstico se confirma con un estudio completo de hongos (examen directo y cultivo para hongos en agar Sabouraud). El estudio anatomo-patológico, aunque permite visualizar perfectamente a los agentes fúngicos, por su demora, no es el método diagnóstico de elección. Una vez hecho el diagnóstico, se debe iniciar un tratamiento temprano, oportuno y adecuado, identificar los factores predisponentes y corregirlos de manera oportuna, ya que esta entidad tiene una alta tasa de mortalidad. Se utiliza la anfotericina B como tratamiento de elección que se mantiene hasta estabilizar al paciente y, en las variedades rinocerebrales o pulmonares, se requiere la eliminación quirúrgica del material necrótico. Algunos autores recomiendan el uso de azoles para estas infecciones, sin embargo, el consenso general es que el mejor tratamiento sigue siendo la anfotericina B y los otros antifúngicos están reservados para casos especiales.
