International competitiveness of value chains for sugar beet and sugarcane: a combined approach to estimate production and processing costs in Brazil and Germany
Authors: Balieiro Samuel , de Witte Thomas , Lehnberger Andreas
Published: November 2019

With the liberalization of the European sugar sector, the industry is free to export sugar to the world market, competing with other sugarcane producing countries. To understand competitiveness, it is imperative to compare total production costs, including both raw material (farm) and processing costs (mill). Therefore, farmlevel production costs from agri benchmark combined with an engineering approach to calculate processing costs were merged to calculate sugar production costs in Germany and Brazil. The necessary data related to investment costs and technical coefficients was obtained in collaboration with BMA. Results show that processing one ton of white sugar (excluding raw material costs) from sugarcane in Brazil is more than USD30/t cheaper than processing sugar beet in Germany. Including raw material costs and the sales of byproducts, white sugar production in Brazil has a total cost advantage of USD112/t over German factories. Key differences in production costs are associated with labor (20%), depreciation (20%) and energy costs (40%). The findings indicate that even with equivalent raw material costs, the lower net processing costs are a major competitive advantage for Brazilian sugar producers. The combination of the typical farm approach and the dynamic engineering model can be applied to other regions, allowing for the estimation of regional production and shifts in global sugar supply.
The endurance test: A virtual project team's lived experience in an online project management course
Authors: Lohle Michael , Terrell Steven
Published: November 2019

This case study examines longitudinal data stored in the learning management system (LMS) of an online MBA program’s project management course to understand and describe the lived experience of a virtual student team that exhibited difficulty delivering a term project. Testing the constructs of a theoretical model previously proposed in literature, the findings consider whether the model design can be applied in a specific situation and suggests additional case studies are warranted for further understanding. The findings also confirmed two concerns. First, unless students actively contact their instructor to escalate feedback about progress, it is difficult to assess a given student’s contribution to virtual team projects. Second, the instructor actively solicited feedback and facilitated closure to compensate for a lack of student accountability, prompting concern about whether requiring an online instructor’s constant oversight and engagement is an optimal strategy for effective project delivery on virtual student teams.
Strong password? Not with your social network data!

Published: November 2019

Passwords are the standard means of registration and access to Websites, information systems, online services and various social networks. Databases are increasingly breached and social engineering is employed to obtain usernames and passwords for online fraud, therefore, there is a need to secure existing passwords, and to create ones that will be more crack-resistant. This study addresses the issue of personal data, which users enter on social networks, and incorporate in passwords, as well as how tracking and identifying this data assists hackers in cracking these passwords. The study focuses on Facebook, conducting an online anonymous questionnaire among 195 respondents, and an experiment among a voluntary response sample of 72 participants, in which passwords were tried to been deciphered by a custom dictionary attack. The findings confirm a link between the use of accessible online personal data and success rates of password deciphering. The findings underscore the grave threat to users’ information security - not only as a result of their voluntary exposure of personal data on social networks, but also due to the integration of this data into their passwords. The study argues the need to emphasize users' awareness to their password strength, with this vulnerability in mind.

Authors: Polak Przemyslaw , Jurczyk-Bunkowska Magdalena
Published: November 2019

This article proposes the use of Quality Function Deployment (QFD) matrix diagram to one of the stages of the innovation process planning. The purpose of this approach is to support knowledge management, specifically the codification of tacit knowledge. Innovation processes are usually carried out by multidisciplinary teams in which arrangements are often problematic due to communication problems. An example of the choice of an innovative solution in a manufacturing company shows the extent to which the use of the QFD method diagram helps to share knowledge in order to take decisions related to planning the goal of the innovation process. We proposed the modification of QFD matrix to include the scale of risk characterizing each of analyzed solutions.
KEPEMIMPINAN DALAM GEREJA SEBAGAI PELAYANAN
Authors: Borrong Robert P.
Published: November 2019

Kepemimpinan dalam gereja bukanlah pelaksanaan kekuasaan atau otoritas manusia melainkan suatu kegiatan pelayanan. Pelayanan yang ditujukan kepada Yesus Kristus, Pemilik dan Kepala Gereja. Gereja ada karena panggilan untuk mewartakan Kerajaan Allah di dunia. Oleh sebab itu kepemimpinan tidak terutama berkenaan dengan penataan organisasi gereja tetapi berkenaan dengan penataan pelayanan gereja kepada Tuhan dan bagi dunia. Kepemimpinan gereja tidak bertujuan membuat organisasi gereja dengan baik, tetapi menata organisasi gereja dengan baik supaya pelayanan dan kesaksian kepada dunia berjalan dengan baik.Pemimpin-pemimpin dalam gereja adalah pelayan-pelayan yang bekerja dengan sukacita dan sukarela karena adanya panggilan dari Tuhan bagi mereka untuk mengambil bagian dalam karya Yesus Kristus di dunia yaitu memberitakan keeselamatan yang telah diberikan kepada dunia oleh dan melalui pengorbanan Yesus Kristus di atas kayu salib. Oleh sebab kepemimpinan adalah panggilan, maka kepemimpinan dijalankan dengan sukarela dan sukacita. Itulah hakekat kepemimpinan sebagai pelayanan gereja. Menjadi pemimpin yang melayani berarti menjadi pemimpin yang memberikan dirinya untuk mengabdi kepada Tuhan, bukan kepada manusia

Homossexualidade sob a ótica de Durkheim: conhecimento, preconceito e luta
Authors: Da Silva Renan Antônio , Muzzeti Luci Regina
Published: November 2019

O objetivo deste artigo é mostrar, sob a ótica da sociologia, alguns aspectos sobre a homossexualidade e o preconceito latente existente em nossa sociedade. Recorre-se à literatura nacional e internacional para esta discussão que tem como conceito central a homofobia e como foco estratégico, a análise do trabalho de Émile Durkheim. A busca pelo respeito e pela dignidade homossexual passa pela criação de leis, movimentos e manifestos populares, pois a aceitação do "diferente" é o principal fator para a efetivação de garantias de direitos desse segmento social. A educação tem um papel especial visando à mudança cultural, cabendo-lhe, mais que ensinar matérias, incentivar a convivência, o diálogo, e os projetos que promovam a riqueza da diversidade humana.
Apesar dos avanços: obstáculos ainda persistem
Authors: Tabak Fanny
Published: November 2019

As décadas de 80 e 90 do século XX revelaram um avanço significativo da presença feminina em importantes áreas da Ciência e Tecnologia, no Brasil. Tanto nos cursos universitários como no mercado de trabalho, também no ensino de nível médio, houve uma contribuição importante da rede dos CEFETs no sentido de proporcionar a um número cada vez maior de meninas a oportunidade de fazer um curso técnico e obter uma profissão. Graças a isso e a uma série de iniciativas resultantes de políticas públicas de apoio, muitas meninas e mulheres cientistas se destacaram e comprovaram seu talento e criatividade. No entanto, diferentes formas de discriminação e preconceitos ainda persistem na sociedade brasileira e se constituem num obstáculo a superar.

Published: November 2019

The immature stages (egg, mature larva and pupa) of Squamapion atomarium (Kirby, 1808), as well as its development cycle and the phenology of its developmental stages, are described for the first time. The larva and pupa of S. atomarium have typical morphological features of the subfamily Apioninae. Morphological data on the immature stages were compared with the only fully described Squamapion species, S. elongatum (Germar, 1817). The larvae of the two species differ in body size and shape, head shape, setae length, the chaetotaxy of the mouthparts, and individual types of setae on the pronotum and thorax. In the case of the pupa, there are also differences in body size and in the type of setae and chaetotaxy of the head, pronotum, metanotum and abdomen.

Cet article met en lumière les changements socio-spatiaux que connait le plateau du Yagour et qui devraient l’affronter incessamment à de nombreux défis, notamment ceux de sa mise en tourisme. Dans un second temps, nous analysons l’impact que pourrait avoir la valorisation par le tourisme sur ce territoire et ses populations. Enfin, en tenant compte de la grande diversité des acteurs opérant sur ce territoire, nous questionnons le rôle de la médiation et celui du tourisme comme « opérateur » facilitant la médiation entre les acteurs dans le but de répondre aux nouveaux enjeux territoriaux.
Nationalism and social movements: a complex interface
Authors: Sen Elsa Tulin
Published: November 2019

Cet article étudie l’interdépendance complexe entre les théories du nationalisme et des mouvements sociaux. Bien que les mouvements nationalistes et les mouvements sociaux partagent nombre de similitudes en termes d’organisation et de mobilisation, la littérature reliant ces deux thèmes est quasi inexistante. Je propose de revisiter les théories sur le nationalisme et les mouvements sociaux avant de discuter de leur éventuelle jonction. Ma contribution est que les mouvements nationalistes sont susceptibles de se transformer en mouvements sociaux lorsque leurs objectifs initiaux sont avancés mais ne sont pas pleinement réalisés. Pour corroborer cet argument, je me fonde sur une étude des mouvements contemporains basque, nord-irlandais et kurde.

Published: November 2019

Exchanging information with peers may support older adults' management of aging-related health changes, including frailty. The current pilot study used a mixed-methods approach to develop and evaluate an online virtual community for older adults to discuss aging-related health issues and management strategies. Eight older adults (mean age = 84) were enrolled at the start of the study. During a 10-week moderated discussion, participants contributed a total of 133 responses. Common themes included (a) symptoms (e.g., pain, weakness/tiredness, sleep difficulties) and (b) management strategies (e.g., health behavior changes, psychosocial support). A positive trend of change was noted in participants' average self-reported health and chronic disease management self-efficacy scores. This platform could facilitate information exchange among older adults, empowering them to leverage their own knowledge to improve their health management strategies. Future research should expand on this study to include older adults of diverse racial, educational, and cultural backgrounds. [

The Willow Ceremony: Professional Socialization for Nurse Practitioner Students

The socialization and transition of nurses into the nurse practitioner (NP) role can be tumultuous and stressful. It may also be somewhat unique in health care education because it builds on the foundation of undergraduate and entry-level nursing. Health care educational programs have used a variety of mechanisms to help students with professional socialization, including formal courses and orientations. In medicine, pharmacy, and dentistry, white coat ceremonies have been initiated as part of a larger process of inculcating professional values (Brown, Ferrill, & Pankaskie, 2003; Gillon, 2000; Peltier, 2004). During these ceremonies, there is usually a presentation of coats, a recitation of an oath, a speech by an honored guest, and a reception (Brown et al., 2003). [more...]
Optical Coherence Tomography Angiography in Amblyopia
Authors: Kaur Savleen , Singh Simar Rajan , Katoch Deeksha , Dogra Mangat R. , Sukhija Jaspreet
Published: November 2019

BACKGROUND AND OBJECTIVE:

The posterior segment of the eye has been investigated in the pathogenesis of amblyopia, but no abnormalities have yet been reported consistently.

PATIENTS AND METHODS:

In this prospective study, treatment-naïve amblyopes aged 6 years to 12 years with best-corrected visual acuity in the amblyopic eye between logMAR 0.3 and logMAR 0.7 and logMAR 0.1 or better in the contralateral eye were recruited. All patients underwent optical coherence tomography angiography (OCTA) imaging of the retina and choriocapillaris.

RESULTS:

The mean age of the 14 recruited patients was 10.26 years ± 1.31 years. The choriocapillaris vessel density was found to be attenuated in the amblyopic eye as compared to the fellow eye. There was a significant difference in the choriocapillaris vessel density between the amblyopic (39.61% ± 0.45%), and the fellow eye (44.10% ± 0.37%;
P
= .005). The choriocapillaris vessel density correlated positively with the visual acuity (r = 0.41;
P
= .03).

CONCLUSION:

The pathogenesis of amblyopia may involve the choriocapillaris, which is the primary source of blood supply for the photoreceptors.

Intraocular Deposition of Copper and ERG Findings in a Patient With Progressive Vision Loss From Hypercupremia
Authors: Donovan Christopher P. , Bhaleeya Swetangi D. , Tzekov Radouil T.
Published: November 2019

A 46-year-old woman who presented for progressive glare was found to have dense deposition of copper within Descemet's membrane and lens capsule in both eyes (OU). Systemic workup revealed elevated serum copper secondary to multiple myeloma. Following bilateral Descemet stripping automated endothelial keratoplasty and cataract extraction, a green discoloration of the vitreous was noted. The patient was followed for 3 years with serial exams and electroretinograms. Electroretinograms showed declining photopic response amplitude OU, indicative of progressive retinal toxicity from copper. Although retinal toxicity and vitreous copper deposition are common in chalcosis, this appears to be the first case of hypercupremia associated with these findings.

Brass’Art à Molenbeek : laboratoire urbain du « faire-ensemble »
Authors: Fadil Nadia , Kolly Maryam
Published: November 2019

Ce papier prend le cas du café culturel Brass’Art, situé sur la place communale de Molenbeek, comme point de départ d’une étude qui vise a comprendre la construction d’un espace commun urbain à vocation pluraliste. Basé sur une ethnographie entre mai 2017 et janvier 2018, cet article veut montrer comment la présence de l’alcool dans ce lieu mobilise et concentre des répertoires divers, voire contradictoires – de types discursif, éthique et affectif – activant la constitution de l’espace public. Le cas d’étude de Brass’Art est emblématique en ce qu’il reflète à l’échelle micro et locale les implications d’une coexistence entre acteurs avec des sensibilités et des orientations religieuses diverses. Suivant une méthodologie pragmatiste, le papier essaie de démontrer que le subtil rééquilibrage du rapport de force entre majoritaires et minoritaires ne se fait pas tant par des négociations conscientes ou des stratégies d’« indifférence civique » que par des ajustements pratiques au principe d’un « faire-ensemble ».
An Open Educational Resources Journey
Authors: Tucker Barbara Graham
Published: November 2019

The open educational resources movement in higher education has largely been driven by concerns over increasing textbook costs and the resulting barriers to access. As the movement has gained traction in sectors of higher education, research has focused on achievement of student learning outcomes. Advocates of OERs point to research indicating that students do as well, and sometimes better, with OERs as with traditionally published textbooks. A study of 10 grant-funded OER projects in a Southeastern access public college found comparable results with the adoption of OERs but not the same level of improvement found in other studies. A deeper investigation into the work involved in the creation of an OER for a multi-section communication course found interesting patterns of use by students as well as a set of lessons learned for the creators.

As part of a data mining competition, a training and test set of laboratory test data about patients with and without surgical site infection (SSI) were provided. The task was to develop predictive models with training set and identify patients with SSI in the no label test set. Lab test results are vital resources that guide healthcare providers make decisions about all aspects of surgical patient management. Many machine learning models were developed after pre-processing and imputing the lab tests data and only the top performing methods are discussed. Overall, RANDOM FOREST algorithms performed better than Support Vector Machine and Logistic Regression. Using a set of 74 lab tests, with RF, there were only 4 false positives in the training set and predicted 35 out of 50 SSI patients in the test set (Accuracy 0.86, Sensitivity 0.68, and Specificity 0.91). Optimal ways to address healthcare data quality concerns and imputation methods as well as newer generalizable algorithms need to be explored further to decipher new associations and knowledge among laboratory biomarkers and SSI.

Early detection and prediction of dementia through unobtrusive techniques or obtrusive tests is still in exploratory status and despite the increase of interest in recent years, many challenges remain open in designing methodologies that can accurately predict its onset. This chapter addresses the problem of the early detection of dementia from two points of view: Detection based on unobtrusive paradigms both in lab and home environments (behavioral monitoring, serious games, home based assisted living applications in telemedicine) and detection based on neuroimaging approaches. The chapter also provides information on setting up ecologically valid home labs for dementia related experiments. Consequently, the aim of this chapter is to provide an overview of a complete methodology of how researchers can possibly detect or predict the onset of dementia through the current state-of-the-art, underline open challenges and illustrate future work in the field.
Billing and Review Perspectives in Healthcare
Authors: Fredrickson Joel
Published: November 2019

The relatively recent and more pervasive retention of electronic healthcare data has provided new opportunities for the advancement of analytics and business intelligence tools within healthcare. The tasks comprising the delivery process for healthcare provide numerous points for data capture, and associated analyses to improve efficiencies and quality of care. In general, healthcare data is extracted from transaction-based systems designed for billing, scheduling, and workflow. However, data characterizing medical events can be further leveraged to assist in the diagnosis and treatment of patients. In fact, healthcare information technology (HIT) to improve patient diagnosis and treatment is remarkably neglected. This chapter outlines the process flow for healthcare delivery, describes the data extracted during this process flow, details the enablers and inhibitors of HIT and accompanying analytics, presents concerns about data integrity and quality, and provides some methods for data cleansing and staging.
Study of Financial Warning Ensemble Model for Listed Companies Based on Unbalanced Classification Perspective
Authors: Cong Wei
Published: November 2019

Using the ensemble learning method to mine valuable information from a sea of financial data accumulated on the market of financial securities is very important for studying data processing. On the basis of financial data from A-share companies listed on Shanghai Stock Market, this article takes the perspective of unbalanced classification of ST stocks to carry out a study of the construction of a financial warning model for the listed companies. In our experiment, HDRF (HDRandom Forest, Hellinger Distance based Random Forest), ensemble classification models of Bagging, AdaBoost, and Rotation Forest, which take Hellinger distance decision tree (HDDT) as the base classifier, and the ensemble classification model which takes the C4.5 decision tree as the base classifier, are compared in respect of both the area under the ROC curve and the F-measure. As shown in the experimental results, the HDRF and the HDDT based classifier, as an ensemble method, are effective for financial data of listed companies.

Published: November 2019

Big Data is an important topic for discussion and research. It has gained this importance due to the meaningful value that could be extracted from these data. The application of Big Data in the modern business allows enterprises to take faster and smarter decisions, achieving a real competitive advantage. However, a lot of Big Data projects provide disappointing results that don't address the decision-makers' needs due to many reasons. The main reason for this failure can be summarized in neglecting the study of the decision-making aspect of these projects. In light of this challenge, this study proposes the integration of decision aspect into Big Data as a solution. Therefore, this article presents three main contributions: 1) Clarify the definition of Big Data; 2) Presents BD-Da model, a conceptual model describes the levels that should be considered to develop a Big Data project aiming to solve a problem that calls a decision; 3) Describes a particular, logical, requirements-like approach that explains how a company develops a Big Data analytics project to support decision-making.
A Simulated Annealing Based Centre of Mass (SAC) Approach for Mesh Routers Placement in Rural Areas
Authors: Fendji Jean Louis Kedieng Ebongue , Thron Chris
Published: November 2019

The problem of node placement in a rural wireless mesh network (RWMN) consists of determining router placement which minimizes the number of routers while providing good coverage of the area of interest. This problem is NP-hard with a factorial complexity. This article introduces a new approach, called the simulated annealing-based centre of mass (SAC) for solving this placement problem. The intent of this approach is to improve the robustness and the quality of solution, and to minimize the convergence time of a simulated annealing (SA) approach in solving the same problem in small and large scale. SAC is compared to the centre of mass (CM) and simulated annealing (SA) approaches. The performances of these algorithms were evaluated on a set of 24 instances. The experimental results show that the SAC approach provides the best robustness and solution quality, while decreasing by half the convergence time of the SA algorithm.

Published: November 2019

The correctness of transformations has recently begun to attract the attention of the researchers in Model Driven Engineering (MDE). The objective of this article is twofold. First, it presents an approach for transforming BPMN models to Colored Petri nets models using GROOVE and EMF/Xpand tools. Second, it proposes an approach for checking the correctness of the transformation itself. More precisely, we have defined the termination property of the transformation and the preservation of some structural properties of BPMN models by the transformation using the GROOVE graph transformation tool. The authors have also applied the approach on a case study through which the authors have verified the successful termination of the transformation using GROOVE Model Checker and the target model properties using CPN Tools.

Professional development of teachers and the role it plays in improving teacher quality is a topic of considerable interest. The authors of this study examined the effectiveness of professional development (PD) to improve the quality of teaching for 21 reading teachers participating in a No Child Left Behind Summer Reading Institute. Data collection occurred over the four-week period of the Institute and two follow up sessions during the academic year 2017-2018. Data evaluation was both quantitative and qualitative in nature. The results suggest that PD helped this group of Mississippi Delta reading teachers improve in both content knowledge and pedagogical practice. The authors conclude that such PD plays a critical role in improving teacher quality from the underrepresented and underserved areas of the Mississippi Delta. Future studies could investigate the direct effects of PD programs such as that offered by the Institute on participating teachers students' learning outcomes.
Improving Indian Teachers' Readiness to Adopt New Methodologies
Authors: Narayanan Nandini
Published: November 2019

Appropriate pre-service and in-service professional development programs help improve teacher effectiveness. Though the Indian government has invested substantial resources on in-service teacher training, teachers rarely implement the learning from such programs in the actual classroom. This article draws insights from a qualitative analysis of the teacher training conducted during a larger study that developed and tested an intervention program for language learning problems in Marathi, and Indian language. It discusses the current status of in-service teacher training in India and identifies important practice implications that could be used as a basis for more detailed research in this field and for reforming teacher training in India. Based on the interactive and learner-centered teacher training method used in this study and the positive impact it had on the two teachers who participated, the author recommends methods to help teachers challenge, re-examine, and re-structure teachers' belief systems related to teaching children.

The condition factor between males and females (t = 2.1545; p < 0.05) shows distinguished values, with females having higher averages. Fragments of allochthonous insects and plant matter make up the basis of the species' diet. The study showed that the population of A. cf. paranae is predominantly females and have the highest standard for length and weight, which may favor biological diversity and increased larvae and juveniles, maximizing the chance of individuals reaching adulthood. The species prefers an environment with predominance of rocks and logs, which favors shelters. Its diet comes mostly from the riparian forest, with a high dependence on the allochthonous items, thus, these vegetations are very important for maintaining populations of the species.
Minimizing diagnostic blood loss in critically ill patients
Authors: Gleason E , Grossman S , Campbell C
Published: November 2019

BACKGROUND: Blood loss from diagnostic procedures in critically ill patients needs to be minimized. Traditionally, when drawing blood from arterial lines, the initial sample used to clear the line has been discarded (open method). Use of a temporary reservoir enables this discard sample to be returned to the patient (closed method). METHODS: Critically ill surgical patients were prospectively randomized to the open or closed method of drawing blood from arterial lines. Blood loss to diagnostic sampling was measured in both groups. RESULTS: A comparison study (n = 1657) of these two methods revealed that blood loss to the patient was significantly decreased (P << .01) using the closed method. Mean blood loss per patient per day was 69 mL in the open group (n = 873) vs 35 mL in the closed group (n = 784). CONCLUSIONS: Use of the closed method when drawing blood from arterial lines results in a significant decrease in blood lost to diagnostic procedures.
Preparing advanced practice nurses for acute care
Authors: Clochesy JM , Daly BJ , Idemoto BK , Steel J , Fitzpatrick JJ
Published: November 2019

BACKGROUND: As a result of changes occurring in healthcare, providers have become increasingly specialized, resulting in fragmented care of patients and their families. With these changes, the need has developed for professionals who possess both advanced clinical decision-making ability and expanded psychomotor skills to serve as case managers in collaboration with physicians. As a result, evolving and innovative roles for advanced practice nurses have developed in American hospitals. The development of such roles, within the acute care hospital environment, has led directly to the creation of graduate programs to prepare acute care nurse practitioners. OBJECTIVE: This article describes the efforts to develop a specific graduate program to prepare nurses as acute care nurse practitioners. These efforts include the needs assessment, curriculum and role development, implementation, and evaluation of the program. RESULTS: Phase 1 evaluation showed significant support for acute care nurse practitioners. External support for the training and use of nurse practitioners in acute care was evidenced by significant financial support for this program provided by an acute care hospital and a private foundation. The first graduates are now practicing as acute care nurse practitioners; Phase 2 evaluation of patient outcomes is under way. CONCLUSION: The emergence of acute care nurse practitioners has been stimulated by changes in American healthcare. Support for the use of acute care nurse practitioners is significant, but barriers to implementing the role and patient and fiscal outcomes must be studied.
Time to hemostasis: a comparison of manual versus mechanical compression of the femoral artery
Authors: Bogart MA
Published: November 2019

BACKGROUND: Compression of the femoral artery to achieve hemostasis is necessary following angiographic and interventional cardiovascular procedures. OBJECTIVES: To evaluate length of time to hemostasis with manual versus mechanical compression of the femoral artery. METHODS: In a prospective study of 503 patients randomized into one of three groups, manual compression with a pressure dressing or vascular stasis button was used on groups 1 and 3, respectively. Mechanical compression with a pressure dressing was used on group 2. The length of time to hemostasis was measured in minutes. Demographic data, current medications, risk factors, laboratory values, and procedural data were analyzed. RESULTS: Mean time to hemostasis was 22 minutes with manual compression and 31 minutes with mechanical compression. Crossover from mechanical to manual compression to achieve hemostasis occurred in 21 of 168 patients (13%). CONCLUSIONS: Results of this study show that advantages of manual compression include shorter time to hemostasis, no requirement for special equipment, and the ability to remove arterial and venous sheaths simultaneously. Disadvantages include upper extremity fatigue and human resource considerations. If the operator is a nurse, the cost of compression increases and the ability to meet patient needs may be restricted. Although mechanical compression is a "hands free" approach, arterial hemostasis is prolonged, special equipment is required, and the total cost per procedure is higher.
Comparison of 2 methods of managing gastric residual volumes from feeding tubes
Authors: Booker KJ , Niedringhaus L , Eden B , Arnold JS

BACKGROUND: Research-based standards do not exist for the management of gastric residual volumes from feeding tubes. Withdrawing and returning residual volumes can lead to clogged tubes and exposes patients to possible contamination of the feeding system. However, discarding residual volumes may place patients at risk for electrolyte imbalance and may alter fluid or nutritional balance. OBJECTIVES: To investigate the effects of discarding versus returning gastric residual volumes on body weight, serum electrolyte levels, and the rate of complications associated with tube feeding. METHODS: Thirty-five subjects receiving enteral feedings were recruited from intensive care units at 3 Midwest hospitals and randomized to a discard group or a return group. Eighteen sets of usable data were obtained. RESULTS: Repeated-measures analysis of variance indicated no significant differences between the 2 groups for any of the variables. Complications related to enteral feedings were more common in the return group (n = 8), which had 2 episodes of tube clogging and 1 episode of diarrhea and nausea. None of these complications were experienced by patients in the discard group (n = 10). CONCLUSIONS: Both groups had significant numbers of complications, including a total of 15 episodes, 7 in the discard group and 8 in the return group, of feeding delays due to high gastric residual volumes. Although serum electrolyte levels did not differ significantly between the 2 groups, potassium levels tended to be lower in the discard group. Considerations for the care of critically ill patients with feeding tubes are discussed in light of these findings.
Elderly patients' reports of physical restraint experiences in intensive care units
Authors: Minnick A , Leipzig RM , Johnson ME
Published: November 2019

BACKGROUND: Use of physical restraints has undesirable sequelae. As they weigh the risks and benefits of protocols for reducing the use of restraints, staff members in intensive care units, where restraints are most used in hospitals, need to know how well elderly patients remember being restrained and how patients perceive the use of restraints. OBJECTIVES: To estimate the proportion of patients who remember being restrained, describe the experience from the patients' perspectives, and describe any distress caused by use of restraints within the overall experience of being in the intensive care unit. METHODS: Transcripts of semistructured, audiotaped interviews of patients who had been in the medical or surgical intensive care unit in any of 3 eastern and midwestern medical centers were analyzed by question and for overall themes. RESULTS: Six patients (40%) remembered some aspect of being restrained but did not report great distress. Patients accepted restraints as needed because of the lack of alternatives. Patients reported remembering that they should not perform certain behaviors but being unable to stop themselves. Patients cited hallucinations and intubation as major stressors in the intensive care unit. Patients' continuing health problems after discharge from the intensive care unit severely limited recruitment of subjects. CONCLUSIONS: Patients do not remember great distress specifically related to the use of restraints, but the overall situation leading to use of restraints is disturbing if remembered. The discovery of methods to reduce the distress of intubation and hallucinations could decrease use of restraints.

• Background Myoelectric noise and baseline wander, artifacts that appear when patients move during electrocardiographic monitoring, can cause false alarms. This problem can be addressed by using a reduced lead set and placing electrodes on the anterior part of the torso only. The Mason-Likar modification of the standard 12-lead electrocardiogram and the EASI lead system are 2 alternative systems for lead placement.

• Objectives To test the hypothesis that the EASI lead system is less susceptible to artifacts than is the Mason-Likar modification of the standard 12-lead electrocardiogram.

• Methods Baseline wander and myoelectric noise amplitudes of EASI and Mason-Likar 12-lead electrocardiograms were compared. Twenty healthy volunteers participated. Both lead systems were recorded simultaneously for different types of physical activities. For each lead in each subject, baseline wander and myoelectric noise were measured for both systems, at rest and during each physical activity.

• Results The outcome for baseline wander was mixed. For myoelectric noise content, the EASI system performed better for the limb leads in the different physical activities. In the precordial leads, the differences were minimal or mixed. However, for supine-to-right turning, EASI performed worse than the Mason-Likar system.

• Conclusions The 2 systems have similar susceptibilities to baseline wander. The EASI system is, however, less susceptible to myoelectric noise than is the Mason-Likar system. EASI performed worse than Mason-Likar for turning supine to right, because only the EASI system uses an electrode in the right-midaxillary line.
Use of the Trendelenburg Position as the Resuscitation Position: To T or Not to T?
Authors: Bridges Natalie , Jarquin-Valdivia Adrian A.
Published: November 2019

• Objective To review the literature on use of the Trendelenburg position as a position for resuscitation of patients who are hypotensive.

• Methods PubMed online, cited bibliographies, critical care textbooks, and Advanced Cardiac Life Support guidelines were searched for information on the position used for resuscitation. Because of the heterogeneity of the data, only pertinent articles and chapters were summarized.

• Results Eight peer-reviewed publications on the position used for resuscitation were found. Pertinent information from 2 critical care textbooks and from the Advanced Cardiac Life Support guidelines was included in the review. Literature on the position was scarce, lacked strength, and seemed to be guided by “expert opinion.”

• Conclusion The general “slant” of the available data seems to indicate that the Trendelenburg position is probably not a good position for resuscitation of patients who are hypotensive. Further clinical studies are needed to determine the optimal position for resuscitation.
