Relationship of Supplement Intake Behavior to Performance and Grazing Behavior of Cattle Grazing Mixed-Grass Rangelands
Authors: Wyffels Samuel A. , Dafoe Julia M. , Parsons Cory T. , Boss Darrin L. , DelCurto Timothy
Published: March 2021

This study evaluated the relationships between supplement intake behavior, beef cattle performance, and grazing behavior on dormant northern mixed-grass rangelands. In each of two years, a commercial herd of bred cows grazed a rangeland pasture from November to January. All cattle were managed as one contemporary group. Calf birth date, birth weight, and adjusted 205-day weaning weight were collected for each cow following the grazing season each year as cow performance metrics. During the grazing season, all cattle were provided free-choice access to a self-fed supplement. Supplement intake behavior was measured for each individual. Grazing behavior was monitored for 30 randomly selected individuals. The relationship of individual average daily supplement intake (R = 0.65; ρ = 0.65), supplement consumption rate (R = 0.58; ρ = 0.54), the coefficient of variation of supplement intake (R = 0.51; ρ = 0.50), and the amount of time spent at the feeder (R = 0.47; ρ = 0.49) were positively correlated and ranked across years (P < 0.01), suggesting individual animal supplement intake behavior is repeatable for cattle grazing dormant season rangelands. Additionally, there were multiple significant associations between supplement intake behavior, cattle performance, and grazing behavior (P ≤ 0.05); however, the majority were weak associations that accounted for minimal variation in cattle performance and grazing behavior (R ≤ 0.27; r2 ≤ 0.07). Although supplement intake behavioral traits were repeatable across years, its use as a metric to predict animal performance and grazing behavior may be limited.
Queer Families, Queer Futuresin Dombey and Son
Authors: McLaughlin Joe
Published: March 2021

What did Dickens know about queer theory before it was written? While the debate between the antisocial thesis and queer utopianism continues to yield productive fruit in the realm of critical theory, this article argues for a formal analysis of queerness in Dickens, reading Dombey and Son as a novel about various kinds of queer families in a time of distress and dysfunction. Following Caroline Levine's notion of social forms, this article examines the formal collisions between various kinds of queer families, which both articulate and open up new ways to define “the queer” and what place or function queerness can have within the larger construction of the social. Through primary engagement with Lee Edelman and José Esteban Muñoz, it finds that Dickens saw deeply into the possibilities for queer studies, articulating not one, but many affordances that queerness could provide. By reintegrating Dickens into queer theory, this article also reexamine Dickens's reputation as the novelist of family values, arguing at once that Dickens's domestic ideal works to underscore the irony of its unattainability, while also pushing him towards queer constructions more capable of maintaining such an ideal.
Eco-criticism(s) and Victorian Fiction: A Review Essay
Authors: Tait Adrian
Published: March 2021

This article offers an overview of the now burgeoning field of Victorian ecocriticism. Ecocriticism (or environmental criticism) emerged as a distinct field of study in the 1990s, focused on reevaluating Romantic and nonfictional representations of nature as part of a green tradition of deep ecological thinking. As ecocriticism diversified, it took a more sociocentric (or social ecological) turn, and in so doing, it also took a more active interest in the Victorian period. As a new generation of ecocritics have emphasized, the Victorian period marked an epochal shift in the nature of lived existence, as a rural society was transformed into an industrialized, urbanized, and recognizably modern society, with recognizably modern environmental problems. In reacting to those problems, Victorian writers anticipated many of our own concerns, as recent ecocritical reconsiderations of Dickens's work underline. As the variety of those responses to Dickens's oeuvre also suggest, ecocriticism today encompasses a range of sometimes markedly different theoretical approaches and concerns. Those approaches are nevertheless united by a shared sense that a Victorian ecocriticism constitutes a distinct and worthwhile field of study, with the very real potential to illuminate the origins of the environmental crises bequeathed by the world's first industrial nation.
Fitzgerald, Hemingway, and Morrill Cody
Authors: Caterini Dino J.
Published: March 2021

This article discusses the life and works of Morrill Cody (1901–1987), a journalist who lived in Paris throughout the 1920s and intimately knew Fitzgerald, Hemingway, and other literary and artistic figures associated with the expatriate modernist movement. Cody should be better known than he is, and this article attempts to elevate his reputation among scholars and Fitzgerald researchers who might not be familiar with his life and works. His 1984 book, The Women of Montparnasse: The Americans in Paris (with Hugh Ford), is a personal but seminal work that concentrates on the women who played leading and important roles in 1920s Paris. Cody later became a cultural diplomat who organized a celebrated exhibit in Paris in 1959 on “The Writers of Paris” that a number of figures from the 1920s attended. Cody’s papers were donated to Amherst College and contain letters from Hemingway to Cody as well as other celebrated figures from the 1920s, such as Sylvia Beach, Djuna Barnes, Kay Boyle, and others.
Self-Styled Madness
Authors: Camastra Nicole J.
Published: March 2021

Although no evidence suggests that F. Scott Fitzgerald read Edgar Allan Poe’s little-known tale “The System of Doctor Tarr and Professor Fether” (1845), his posthumously published story “Nightmare (Fantasy in Black)” offers riveting textual opportunities to read it as a development of Poe’s concern for the lunatic, uncontrolled forces within and without the individual that threaten selfhood. Released in 2017 as part of a “lost stories” collection, “Nightmare” has received little critical attention. It provided some material for Tender Is the Night, but reading it as part of an ominous conversation with Poe positions it as an example of Fitzgerald’s darker vision of American ambition: how it cannibalizes the self. This article explores what J. Gerald Kennedy calls the “imaginative genealogy” between both writers, first by contextualizing the composition of their respective stories against the backdrop of personal adversity, professional instability, and an American ethos, and then, by comparing key scenes and characters in the texts themselves. “Nightmare” and “Tarr and Fether” play with the proverbial understanding of reason and madness finally to suggest that, as Fitzgerald’s subtitle implies, there is a “Fantasy” on the other side of the “Nightmare.”
Painting the Pictures
Authors: Reisinger Richard
Published: March 2021

This article addresses the concept of exclusion from one’s ideal social realm, as seen in the characters of Jay Gatsby and Pat Hobby. Both characters find themselves obsessed with inclusion in groups in which they are not welcome. Gatsby, belonging to the world of new money, is enamored with joining the world of old wealth. Pat Hobby is a has-been; he once thrived in the world of silent film, but failed to transition to the “talkies.” Both men exist at the edge of a society that considers them outsiders. When presented with the failure to assimilate and be accepted, each engages in creating a façade that he feels can infiltrate his desired sphere. Gatsby hides behind the mystery of his wealth and the sumptuous parties he hosts. Similarly, Hobby can be considered a chameleon; he adapts his personality and purported skills to match any situation with which he is presented. As with Gatsby, however, his façade is compromised both by inner and outer conflicts, ultimately dramatizing Fitzgerald’s belief that our identities are not ours to invent. This article also aims to bring more critical attention to the Hobby stories; often ignored, these tales, when read with sympathy for the much-disparaged protagonist, show Fitzgerald’s creative and structural genius. In placing these stories in dialogue with Fitzgerald’s magnum opus, the comparisons elevate these later efforts by showing that they share with The Great Gatsby an exploration of selfhood and performativity.

Aim of study: Sports involving horses have notable financial importance. Breeds are evaluated to find the best-suited ones for a specific sport category. Phenotypic diversity using biometric markers was evaluated for Quarter Horse (QH), Arabic (AR), English Thoroughbred (ET), and Brazilian Equestrian (BE) horse breeds.Area of study: Mato Grosso do Sul-Brazil.Material and methods: Lengths, widths, and circumference measures of 268 horses were collected. These measures were used to estimate conformation indexes. The size-free canonical discriminant analysis was used to remove the size effect on the animal's shape. The similarity among breeds (by sex) was evaluated employing multivariate analysis (canonical analysis, MANOVA, principal components, Euclidean distances, and grouping through complete linkage), considering all linear measures and conformation indexes (included in the analysis of principal components).Main results: Four canonical variables (CANs), each one representing an equation to interpret the morpho-functionality of breeds “sustentation”, “structure”, “frame”, and “equilibrium”, were retained. The breeds presented differences when the CANs were simultaneously considered. Differences mainly were the size and the thickness of the body as well as the ability of the animal to move. ET, QH, and BE demonstrate a well-defined biometric profile. These three breeds clustered separately from AR breed.Research highlights: Canonical variables allow to verify the functional aptitudes since the responses were close to conformation indices commonly used as horse skill estimators. The implementation of these variables as selection criteria in horse breeding programs require further studies in larger populations of horses for a confirmation of the present results.

Aim of study: To reduce the sample size in an agricultural area of 167.35 hectares, cultivated with soybean, to analyze the spatial dependence of soil penetration resistance (SPR) with outliers.Area of study: Cascavel, BrazilMaterial and methods: The reduction of sample size was made by the univariate effective sample size ( ) methodology, assuming that the t-Student model represents the probability distribution of SPR.Main results: The radius and the intensity of spatial dependence have an inverse relationship with the estimated value of the . For the depths of SPR with spatial dependence, the highest estimated value of the  reduced the sample size by 40%. From the new sample size, the sampling redesign was performed. The accuracy indexes showed differences between the thematic maps with the original and reduced sampling designs. However, the lowest values of the standard error in the parameters of the spatial dependence structure evidenced that the new sampling design was appropriate. Besides, models of semivariance function were efficiently estimated, which allowed identifying the existence of spatial dependence in all depth of SPR.Research highlights: The sample size was reduced by 40%, allowing for lesser financial investments with data collection and laboratory analysis of soil samples in the next mappings in the agricultural area. The spatial t-Student model was able to reduce the influence of outliers in the spatial dependence structure.
Employee Engagement and the Ethic of Friendship
Authors: Caldwell Cam , Anderson Verl , Ristic Marija Runic
Published: March 2021

The failure of managers and supervisors to earn the trust and followership of the employees with whom they work is well documented in recent research about employee engagement (Clifton & Harter, 2019). Without that employee commitment, organizations inevitably struggle to compete in the global marketplace and fail to achieve their potential (Cameron, 2012). Although much has been discussed in the light of the findings of concerned scholars (HR Research Institute, 2019), disagreement nonetheless exists about the factors which make up employee engagement, as well as the most effective approach that can be taken to increase engagement and those factors. Though there has not been full agreement about the nature of employee engagement, it is widely accepted that the failure of organizations to engage employees has been a serious deterrent to achieving organization results (Clifton & Harter, 2019).Objective: The purposes of this paper are to offer insights into the precise nature of employee engagement and to identify the value of employers adopting the Ethic of Friendship – an ethical perspective that has begun to be written about more frequently in the management literature.Methods: We begin the paper by proposing an integrated and updated definition of employee engagement – identifying nine factors which contribute to its makeup.Results: We suggest that each of these nine factors significantly impact employee engagement and warrant increased attention by organizational leaders. We then address the Ethic of Friendship and its increasingly important role in today’s arms-length and transactional relationship between employers and employees.Conclusions: The paper then clarifies how the Ethic of Friendship addresses all nine of the factors which constitute employee engagement and explains how the Ethic of Friendship can increase the ability of organization leaders, managers, and supervisors to bridge the gap of distrust that often exists in the modern organization. After identifying five important contributions made by this paper, we conclude by encouraging leaders to adopt the Ethic of Friendship’s commitment to treating employees as valued partners and, by so doing, create a culture in which employee engagement is likely to thrive.
Exploring Reflections of Lecturers on Ethics in the Accounting Curriculum: A Case Study of Ukzn and Unizulu, South Africa
Authors: Tewari Ankur Ratnam , Maharajh Lokesh Ramnath
Published: March 2021

The accounting profession has changed considerably over the past twenty years or so. This has led to the new accounting curriculum undergoing many changes such as increased financial fraud coverage, laws relating to financial crime and globalisation and financial security issues. However, there have been many financial scandals in the 21st century in the African and American context. Several notable incidents of ethical misconduct such as Enron, Klynveld Peat Marwick Goerdeler (KPMG), and Satyam (which negatively impact the world economy) are examples of misuse of accounting to cover the truth. Lack of ethics is believed to be responsible for most of these scandals. This study, therefore, aims at understanding the reflections on the issue of ethics in teaching accounting. The study followed a case study approach and involved a small sample of accounting lecturers from UKZN and UNIZULU. The study's findings suggest that special topical issues on ethics should be taught in each accounting course. For example, in the auditing course, ethical procedures should be touched upon, and students should be sensitized about accountants' ethical behaviour.

Authors: Luhmann Scott J. , Kelly Mike P. , Enata Nichelle H. , Brouillet Kirsten , Etienne Ernst , Kelly Brian A.
Published: March 2021

Introduction:

The impact of posterior spinal fusion (PSF) on physical function and pain and mental health in pediatric patients as quantified by the Patient-Reported Outcomes Measurement Information System (PROMIS), developed by the National Institute of Health, is largely unknown. The purpose of this study is to report the changes of PROMIS scores for upper extremity (UE), pain interference (PI), mobility (MOB), and peer relationships (PR) after PSF in patients with idiopathic scoliosis (IS), compare postoperative changes in PROMIS PI and Scoliosis Research Society-30 pain scores, and evaluate associations between curve characteristics and PROMIS scores.

Methods:

A retrospective cohort of 122 patients (<18 years old) who underwent PSF for IS was identified through electronic medical record search. PROMIS scores were obtained preoperatively and 6 weeks, 6 months, 1 years, 2 years, and 3 years postoperatively.

Results:

The mean age of the cohort was 14.2 ± 1.6 years, and the mean Cobb angle was 62.9 ± 13.8° at surgery. Eighty patients had preoperative PROMIS data. UE and MOB scores were statistically lower at 6 weeks and 6 months postoperatively and returned to baseline with a longer follow-up. PI scores were significantly lower at 1 and 2 years postoperatively. PR was unchanged up to 2 years postoperatively and then showed significant improvement. There was a statistically significant negative relationships between lowest instrumented vertebra and PROMIS UE and MOB scores at 6 weeks and 1 year postoperatively, but not at a longer follow-up. There were no significant differences noted in PI and PR PROMIS scores and lowest instrumented vertebra. PROMIS scores were not statistically associated with the Lenke Classification, number of vertebral levels fused, or percentage coronal correction.

Discussion:

Changes in PROMIS functional domains (UE and MOB) postoperatively normalize at longer follow-ups. Changes in PI and PR demonstrated improvements over preoperative values at 1 to 2 years postoperatively. Preoperative coronal and sagittal measures, and the percentage correction did not correlate with any PROMIS scores.

Published: March 2021

Dairy cow manure has high buffering capacity hence a substrate for anaerobic digestion, however the process is not optimised in mono-digestion system due to limited substrate. The aim of the study was to assess the effect of co-digesting animal waste and vegetable waste on methane production. Two systems were applied- batch and continuous anaerobic digestion system to determine effect on methane yield. The experiments were conducted with treatments as: manure alone (M), composite of manure with cabbage (MC), manure with potatoes (MP), manure with cabbage and potatoes (MCP), faecal alone (F), faecal with cabbage (FC), faecal with potatoes (FP) and faecal with cabbage and potatoes (FCP). Rectal grab samples were collected prior to incubation and manure was collected from the pens. All treatments were in replicates. Composite of manure or faecal with cabbage and potatoes produced the highest biogas (FCP: 32.1 mL/g DM, MCP: 29.5 mL/g DM) and methane (FCP: 3.13 mL/g DM, MCP: 2.36 mL/g DM) compared to manure alone or faecal alone (F: 27.0 biogas mL/g DM, M: 26.6 biogas mL/g DM) (F: 1.36 methane mL/g DM, M: 1.18 methane mL/g DM). Co-digesting dairy excreta with cabbage as only vegetable substrate affected anaerobic digestion (FC: 24.8 mL/g DM, MC: 24.9 mL/g DM), since it was the lowest in biogas production compared to all treatments. The anaerobic digestion system had an effect in methane production since continuous anaerobic digestion system produced the highest methane compared to batch anaerobic digestion system in all treatments. The results obtained in this study suggest that composite of manure with both cabbage and potatoes results in the highest biogas and methane production.

Lettuce (Lactuca sativa L.) is considered as the main leafy vegetable in Brazil. In the last decades, there had been many changes in the predominant varietal types in the country, however, issues regarding the use of saline water inhibit the growth by the osmotic effect. The aim of this study is avaliate the effect of water salinity on physiological in lettuce cultivars. The experiment was carried out at the Alagoas Federal University, Arapiraca Campus, in a completely randomized design and with a 5 × 2 factorial scheme, with six replications. Five treatments of water salinity levels were analyzed (ECw: 0.14, 1.54, 2.94, 4.34, and 5.74 dS m-1 at 25 °C) in two types of lettuce crops (Saia Véia and Vitoria Verdinha). Stomatal conductance, net photosynthesis, transpiration rate, water use efficiency, leaf temperature, and green index were assessed at 10, 20, and 30 days after the application of the treatments. The saline stress caused by the increase in saline concentrations decreased the photosynthesis and transpiration rates, which were associated with the reduction of stomatal conductance in both cultivars. Nevertheless, Saia Véia cultivar was higher tolerance in all tested saline levels compared to Vitória Verdinha. The green index for Vitoria Verdinha was seven times higher when compared to Saia Véia from the lowest to the highest saline levels. The cultivars differ in salt sensitivity, which could be useful for producers to choose the cultivar that is most adapted to the region and breeders regarding improvement prospects for adaptation of the lettuce under saline stress. In addition to osmotic stress, which is the first to happen, there are others.
Views of Sports Sciences Students About Distance Education During Covid-19: SWOT Analysis
Authors: Kaya Didem Gülçin
Published: March 2021

This study is aimed to examine the views of the students of the Faculty of Sports Sciences on distance education with SWOT analysis and to evaluate the current circumstance. The phenomenology design was used in the study. The research group consisted of 62 students studying at Afyon Kocatepe University Faculty of Sport Sciences located in a town in the Aegean region in Turkey. In collecting the data, the personal information form created by the researchers and the semi-structured interview form was used, and the data obtained were analyzed by content analysis and descriptive analysis technique. As a result of the findings, it was seen that the views of the students studying in the field of sports sciences on the strengths of distance education provided the best conditions in the Covid-19 process, gained experience in synchronous-online courses and the online system, and to reinforce the knowledge by making use of projects and assignments. Views on the weaknesses of distance education were expressed as the inability of every student to benefit from the right to education under equal conditions, difficulties in accessing the internet, and lack of materials. Besides, the views on the opportunities of distance education were determined as good management of the process, planning the applied courses face-to-face, that is, choosing the hybrid system, motivating the students for the assignments and projects, and making up compensatory programs applied to solve the problems. Socialization of students, unsuitable working environment, anxiety, and negative views of the society towards the education system were recorded as threats and dangers.
Marital Partners' Traits, Psychological Processes in Marriage, and Marriage Characteristics as Predictors of Love in Marriage
Authors: Obradović Josip , Čudina Obradović Mira
Published: March 2021

This study was conducted to determine the predictors of marital love. Sternberg's Triangular Theory of Love (1986) is used as a starting point. Accordingly, a theoretical model that consists of four groups of level 1 predictor variables and a group of level 2 variables is used. The dependent variables in the model include the three dimensions of love: Passion, Intimacy, and Commitment. The research was conducted among 884 married couples from different parts of Croatia. The results show that married women are less passionate and that marriage partners' passion in marriage is greater at the beginning of the marriage without children and when there is a mutual physical attraction between partners. Married women report less intimacy while greater marital intimacy was present in marriages where there is greater partner support. Unlike passion, the experience of intimacy does not vary at different marital stages. Women show less commitment and partners' commitment to marriage is greater when there is greater emotional stability of both partners, greater mutual physical attraction, and partner support. At the end of the paper, limitations on making firmer conclusions based only on the present study are emphasized.

Authors: Poljanec-Borić Saša
Published: March 2021

The paper analyses the attitudes towards digital enterprises and digital transformation in Croatia. The research was conducted in two steps by using semi-structured interviews (N = 17) and focus group (N = 17) qualitative methods. All the research participants had agreed to the recording of the interviews and the focus group. The recorded material was literally transcribed. The discursive analysis of transcripts showed that research participants connected digitalization with modernization and the creation of real, digitally born enterprises. Research participants suggested that the process of digital transformation was perceived as irreversible evolutionary change and that Croatia was lagging behind within the EU and globally. Research participants suggested that Croatia needed a strategic turnaround and the main barriers for this strategic change were embedded in the political and public sectors.

Published: March 2021

This paper presents an edge detection algorithm for omnidirectional images based on superposition law on Bloch’s sphere and quantum local entropy. Omnidirectional vision system has become an essential tool in computer vision, duo to its large field of view. However, classical image processing algorithms are not suitable to be applied directly in this type of images without taking into account the spatial information around each pixel. To show the performance of the proposed method, a set of experimentation was done on synthetic and real images devoted to agriculture applications. Later, Fram & Deutsh criterion has been adopted to evaluate its performance against three algorithms proposed on the literature and developed for omnidirectional images. The results show a good performance of the proposed method in term of edge quality, edge community and sensibility to noise.
Social support for veterans
Authors: Czuba Beata
Published: March 2021

The article aims to outline how mission-traumatized veterans perceive social support. Social support is an essential resource for an individual in coping with the difficulties in everyday life. The subject of the examination is quantitative research with veterans’ participation and own qualitative research – free interviews analyzed using the IPA (Individual Phenomenological Analysis) method. The obtained results indicate that social support can be considered in terms of a meta-resource that activates other vital resources of humans, thereby strengthening them in difficult situations. The expected support criteria are met by friendly self-help groups that can operate in military units and complement the help provided by professionals.

Authors: Pytel Marek , Cieśla Mariusz
Published: March 2021

The Territorial Defense Forces’ combat operations carried out for the benefit of the operational troops will create a hardly permeable network of resistance points (defense zones), which will allow slowing down and ultimately stopping the enemy. However, to perform this task, the TDF operation principles and features when organizing the fight should be borne in mind. Apart from that, they must organize their effective system of reconnaissance, anti-landing, and anti-diversion activities, both in their offensive and protective-defensive forms. They will organize resistance points (defense zones) in specific combat environments as for network defense activities. In the first stage of the defense operation, they will take part in cover operations.

Authors: CHEN Lijia , CHEN Haibin , LI Rongyong , HE Weifeng , YANG Yuhui
Published: March 2021

The Ni coatings were prepared from nickel metal powder and zirconia ceramic balls by mechanical coating technique. The relationship between rotation speed and coatings thickness was studied, the thickness of the coatings was characterized by the weight increase of the zirconia balls after mechanical coating. The composition and microstructure of the coatings with maximum thickness were analyzed by scanning electron microscope (SEM), energy dispersive spectroscopy (EDS), and X-ray Diffraction (XRD). The results revealed that the formation of coatings consists of thickening from the cold welding between Ni particles and the thinning from the exfoliation of coatings work hardening. The thickness of the coatings reaches the maximum when the above two process progress are close to each other. The results proved that higher speed was favor of the coatings formation, the maximum thickness was obtained at the 15 h for rotation speed of 240 rpm, and microscopic images show that the average thickness was about 20 μm.
Wissen und Werte im Widerstreit. Zum Verhältnis von Expertise und Politik in der Corona-Krise
Authors: Bogner Alexander , Menz Wolfgang
Published: March 2021

Im Verlauf der Corona-Krise wird ein verändertes Verhältnis von wissenschaftlicher Expertise und politischer Entscheidungsrationalität deutlich, das sich vor dem Hintergrund sich wandelnder „Thematisierungsweisen“ von Konflikten deuten lässt: Während in einer ersten Phase politische Entscheidungen eng an medizinische und virologische Expertise angebunden blieben, pluralisierten sich mit dem Übergang zur Thematisierung als „Wertkonflikte“ die politischen Bezüge auf Expertenwissen und gewannen an Distanz. Sobald Werteaspekte in den Vordergrund treten, erhöht sich also die Autonomie der Politik; Konflikte hingegen, die sich auf epistemische Aspekte konzentrieren, steigern die Gefahr des Szientismus.

Este estudo procura analisar possíveis contribuições que a discussão filosófica sobre experiência traz para se pensar o ensino das práticas corporais na escola. Para isso, o texto recorre às análises sobre a (re)configuração da categoria experiência na modernidade e defende, no âmbito da Educação Física, que se pense a experiência a partir de um viés enriquecedor: menos centralizado em um ensino fechado/instrumental e mais preocupado com um ensino das práticas corporais de maneira aberta/inesperada. Nesse sentido, o estudo sugere que a tríade práticas corporais/experiência/Educação Física pode enriquecer as experiências corporais, dando um novo sentido à aprendizagem.
One injection for a great projection: a quick and simple procedure for nipple reconstruction

Women attach great importance to the presence of a three-dimensional nipple upon completion of the breast reconstruction process. To meet patients’ expectations, nipple-areolar complex reconstruction should achieve symmetry in position, size, shape, texture, and color, as well as minimizing donor-site morbidity. However, it is well known that regardless of the reconstructive technique, loss of nipple projection can be reasonably expected. We developed and evaluated a quick, simple, and innovative technique using injectable Integra Flowable Wound Matrix to increase nipple projection after reconstruction. Twenty breast cancer patients who underwent nipple reconstruction resulting in unsatisfactory projection were enrolled in our retrospective study. Nipple projection was measured at the time of surgery and after 6 and 12 months. A visual analogue scale was used to assess patients’ satisfaction. Our technique yielded reliable results in terms of the long-lasting maintenance of nipple projection. This method is high-priced, but cost-effective, since one kit may suffice for three patients. Furthermore, our patients were very appreciative of this technique as a single-step, minimally invasive, painless procedure with no reported necessity of re-intervention.

Background There are currently no guidelines for the postoperative wound management of the hard-palate donor site in cases involving mucosal harvesting. This study describes our experiences with the use of an artificial dermis for early epithelialization and transparent plate fixation in cases involving hard-palate mucosal harvesting.

Methods A transparent palatal plate was custom-fabricated using a thermoplastic resin board. After mucosal harvesting, an alginic acid-containing wound dressing (Sorbsan) was applied to the donor site, which was then covered with the plate. After confirming hemostasis, the dressing was changed to artificial dermis a few days later, and the plate was fixed to the artificial dermis. The size of the mucosal defect ranged from 8×25 to 20×40 mm.

Results Plate fixation was adequate, with no postoperative slippage or infection of the artificial dermis. There was no pain at the harvest site, but a slight sense of incongruity during eating was reported. Although the fabrication and application of the palatal plate required extra steps before and after harvesting, the combination of the artificial dermis and palatal plate was found to be very useful for protecting the mucosal harvest site, and resulted in decreased pain and earlier epithelialization.

Conclusions The combination of artificial dermis and a transparent palatal plate for wound management at the hard-palate mucosal donor site resolved some of the limitations of conventional methods.

Health care in acute care settings has become increasingly complex and stressful with rapidly evolving treatment options, a growing aging population with multiple comorbidities, and expectations to deliver high-quality care with less resources to curb rising costs. Numerous studies have documented the ever-growing problem of burnout in health-care providers working in acute care settings and increased provider interruptions leading to medical errors. From 2018 to 2019, a new advanced practice provider (APP) role was tested on a 36-bed inpatient bone marrow transplant unit at the University of Colorado to address these issues. The goal of this role was to alleviate stressors and minimize interruptions that could otherwise contribute to compromised patient care and safety. In addition to improving patient care, the goal of the role is to improve job satisfaction. A description of the role and its development and implementation at the University of Colorado Hospital, Anschutz Medical Campus, is highlighted in this article.
Caplacizumab for Acute Thrombotic Thrombocytopenic Purpura
Authors: V. Katsivalis, PharmD Katherine , Thomas, PharmD Jaime
Published: March 2021

Acute thrombotic thrombocytopenic purpura (aTTP) is a rare microangiopathic hemolytic anemia. Standard of care currently includes plasma exchange and immunosuppressive agents, including glucocorticoids, vincristine, and rituximab. Even with these therapies, relapse occurs in 36% of patients, and mortality ranges from 10% to 20%. Caplacizumab is a novel agent approved for the treatment of adult patients with aTTP in conjunction with plasma exchange and immunosuppressive therapies. It works by binding to the A1 domain of von Willebrand factor (VWF), blocking platelets from binding to VWF and aggregating. In clinical trials, patients who received caplacizumab compared with placebo were more likely to have a normalization of their platelet count, a lower rate of recurrence, and a lower incidence of the composite of aTTP-related death, recurrence, or major thromboembolic event. The side effect profile is rather benign and includes epistaxis, headache, and gingival bleeding. Caplacizumab is only available through specialty pharmacy services due to its high cost. Providers should be aware of and prepared for the prior authorization process required to assist their patients in gaining access to the medication. Currently, there is no formal consensus regarding caplacizumab’s place in therapy for patients with aTTP, but it remains an option for refractory cases.
O discurso do Supremo Tribunal Federal na Ditadura Militar
Authors: Torres Mateus Gamba
Published: March 2021

“Este livro tem como grande mérito mostrar, a partir de rigorosa pesquisa documental e histórica, o papel cumprido pelo Poder Judiciário na repressão estatal ocorrida durante a ditadura iniciada com o golpe de 1964. A obra também mostra o quanto não havia neutralidade nas suas decisões do Judiciário, absorvendo uma mistura ideológica marcada pelo anticomunismo, pela doutrina militar e pelos interesses da burguesia. Embora se refira a questões ocorridas décadas atrás, o debate colocado pelo livro remete o leitor à História do Tempo Presente, na medida em que permanecem os muitos dos elementos estruturantes do conservadorismo jurídico. Concretamente, temos visto em anos recentes leis sendo relativizadas de acordo com interesses políticos e econômicos, prisões arbitrárias e sem provas conclusivas, a intensificação da perseguição a movimentos sociais e até mesmo a manipulação de resultados eleitorais. A presente obra, portanto, ao refletir acerca da ditadura, permite também compreender o processo de crise da chamada Nova República, construída a partir do pacto entre ditadores e setores da oposição em nome da manutenção da ordem burguesa, materializado na Constituição de 1988.”

Published: March 2021

BACKGROUND: Multiple organizations have issued guidelines to address the prevention, diagnosis and management of diabetic foot ulcers. These guidelines are based on evidence review and expert opinion.
METHODS: Literature review was conducted and guidelines were reviewed to identify consensus (or lack thereof) on the nature of these recommendations, the strength of the recommendations and the level of evidence.

RESULTS: Most guidelines were not based on highest level of evidence (randomized controlled trials). A listing of recommendations for prevention, diagnosis and management was created with evidence basis for all recommendations.

CONCLUSIONS: Areas for future research were identified among recommendations based on minimal evidence, areas of controversy, or in areas of clinical care without recommendations.

Genetic regulation of gene expression underlies variation in disease risk and other complex traits. The effect of expression quantitative trait loci (eQTLs) varies across cell types; however, the complexity of mammalian tissues makes studying cell-type eQTLs highly challenging. We developed a novel approach in the model nematodeCaenorhabditis elegansthat uses single-cell RNA sequencing to map eQTLs at cellular resolution in a single one-pot experiment. We mapped eQTLs across cell types in an extremely large population of genetically distinctC. elegansindividuals. We found cell-type-specifictranseQTL hotspots that affect the expression of core pathways in the relevant cell types. Finally, we found single-cell-specific eQTL effects in the nervous system, including an eQTL with opposite effects in two individual neurons. Our results show that eQTL effects can be specific down to the level of single cells.
