Authors: Adewumi Tomi , Delgado Paul , Carr III Marvin , Sowah Emily , Vassar Dr. Matt
Published: May 2022

BACKGROUND

The movement #BlackintheIvory gave Black academics an opportunity to connect through social media, sharing common experiences while pursuing higher education. Through analyzing Twitter posts, using the hashtag #BlackintheIvory, this study investigates the main themes identified among Black scholars in academia and their shared experiences with teaching, mentoring, collegiality, identity, service, and racism.

OBJECTIVE

Through analyzing Twitter posts, using the hashtag #BlackintheIvory, this study investigates the main themes identified among Black scholars in academia and their shared experiences with teaching, mentoring, collegiality, identity, service, and racism.

METHODS

Using the Twitter API, we isolated publicly available tweets, which can include text, images, and links to websites, posted with #BlackintheIvory on the Twitter website (www.twitter.com) from the inception of #BlackintheIvory in June 2020 to the end of December 2020. To evaluate the tweets, we categorized tweets inductively. Based on the content of posts, we identified 6 themes: Teaching, Mentoring, Collegiality, Identity, Service, and Racism.

RESULTS

Our search yielded a total of 12,538 original posts, including tweets between inception in June 2020 to December 2020 from profiles made public (excluding modified and duplicate tweets). We selected and analyzed the top retweeted 2500 tweets, which is 20% (2500/12538) of the total number of downloaded tweets. The greatest percentage of posts were Teaching (881; 35%), Service (441; 18%) and Racism (414; 17%). The remaining tweets were categorized as Collegiality (388; 15%), Identity (210; 8%), and Mentoring (166; 7%) of the total number of tweets from June-December 2020.

CONCLUSIONS

The experiences, perspectives, and narratives among the Black diaspora within #BlackintheIvory are not uniform. The commonality exists within the structural systemic racism which impacts Black academics within the ivory tower, this study is a resounding wake-up call for action.
A Systematic Review Of Devices That Measure And Improve Grip Strength Through Telerehabilitation (Preprint)
Authors: James Sam Prasanna Rajkumar , Karunakar Esther Kavitha , Conrad Megan , Sengupta Sankar
Published: May 2022

BACKGROUND

Grip strength is a vital hand function skill required to perform everyday tasks. Diseases and conditions deteriorate grip strength. Repetitive exercises can improve grip strength, but people are non-compliant with home exercise programs. Gamification of exercises can increase home exercise compliance. A device is needed to measure and rehabilitate grip strength remotely to deliver exercises remotely. A preliminary search on that topic did not provide any review literature on grip strength devices.

OBJECTIVE

We aim to systematically review the various electronic devices and sensors used to measure grip strength.

METHODS

We searched five electronic databases - PubMed, IEEE, Scopus, ACM digital library, and Web of Science. We adapted Barbara and Kitchenham's modified PRISMA guidelines and used PICO to identify keywords and framed research questions.

RESULTS

The search yielded 3546 articles, and after elimination, we included 15 articles for the review.

CONCLUSIONS

We surveyed various devices and sensors that measure grip strength and their capabilities for wireless communication and gamification.
Using voice biomarkers to classify suicide risk in telehealth callers (Preprint)
Authors: Iyer Ravi , Nedeljkovic Maja , Meyer Denny
Published: May 2022

BACKGROUND

Artificial Intelligence has the potential to innovate current practices used to detect imminent risk of suicide, and to address shortcomings in traditional assessment methods.

OBJECTIVE

We sought to automatically classify short segments (40ms) of speech according to low versus imminent risk of suicide in a large number (n = 281) of telephone calls made to two telehealth counselling services in Australia.

METHODS

This retrospective repeated measures cohort design included 281 helpline calls sourced from On The Line, Australia (n=266) and 000 Emergency services, Canberra (n=15). Imminent risk of suicide was coded for when callers affirmed intent, plan and the availability of means; was assessed as such by the responding counsellor, and re-assessed by a team of clinical researchers using the Columbia Suicide Severity Rating scale (C-SSRS = 5/6). Low risk of suicide was coded for in an absence of intent, plan and means and via C-SSRS = 1/2. Pre-processing involved normalisation and pre-emphasis of voice signals, while voice biometrics were extracted using the statistical language r. Candidate predictors were identified using Lasso Regression. The relationship of each candidate biomarker was assessed as a predictor of suicide risk using a Generalized Additive Mixed effects regression Model (GAMM) using splines to account for non-linearity. Finally, a Component-Wise Gradient Boosting model was trained on 60% of the data, then validated and tested on the remaining data (20%/20%).

RESULTS

Seventy-seven imminent risk calls were compared with 204 low risk calls. 171,968 40ms frames featuring 36 voice biomarkers were extracted from these calls. Candidate biomarkers were reduced to 11 primary markers, with distinct models needed for men and women. Classification accuracies greater than 99.9% were obtained for imminent suicide risk for each of the data partitions using these primary markers.

CONCLUSIONS

This study demonstrates an objective, efficient and economical assessment of imminent suicide risk in an ecologically valid setting with potential applications to real-time assessment and response.

Abstract: Approximately 58% of Indian population is involved in agriculture directly or indirectly, which contributed about 19.9% to the GDP of India in 2020-2021 F.Y. According to a report published by ICAR (Indian Council of Agricultural Research) about 30-35% of annual crop yield are wasted because of pests and diseases which affects the income and livelihood of the farmers. With the advancement in deep learning and computer vision it is now possible to detect the plant disease effectively by observing the disease pattern of leaves of plants. Which will help farmers to classify the disease in their plant. In this study about 12500 images of healthy and infected plant leaves which are available in public domain were used to train deep learning model, which can classify the respected disease.

Hiatal hernia surgery: laparoscopic versus robotic approach?
Authors: Komarov R. N. , Osminin S. V. , Bilyalov I. R.
Published: May 2022

Aim. Evaluate the advantages and disadvantages of laparoscopic and robot-assisted anti-reflux operations.

General findings. Reflux esophagitis in the association with hiatal hernia on the third place in the structure of gastroenterological diseases. The development of minimally invasive surgical technologies has led to an increase in the number of laparoscopic and robot-assisted anti-reflux operations. The literature review includes 12 studies, the results of which were published from 2002 to 2020, with a total number of patients 1633. In most of them, when comparing laparoscopic and robot-assisted anti-reflux operations, the advantages of one or another technique were not revealed. In some studies, the high cost and duration of the operation were noted when using the da Vinci robotic surgical complex. Other studies have reported possible improvements in the treatment outcomes of patients with large or recurrent hiatal hernias due to the high precision of movement and improved visualization characteristic of therobot-assisted surgeries.

Conclusion. It is necessary to conduct more researches on this problem to develop indications for the choice of a particular surgical approach, as well as to create a single transparent algorithm for the surgical treatment of patients with reflux esophagitis and hiatal hernia.
Impact of Collaborative Inpatient Pairing Between Pharmacy Students and Family Medicine Residents on Perceptions of Interprofessional Care
Authors: Linn Becky S. , Smith Benjamin Elliott Yelnosky , Cassel Tanner
Published: May 2022

Introduction: Interprofessional education (IPE) and collaborative practice increasingly inform accreditation standards for pharmacy and medical education, grounded in evidence of benefits to patients and learners. Optimizing models that meaningfully provide this type of practice remains a challenge. This study examines the impact of inpatient collaboration between pharmacy students and family medicine residents on perceptions of interprofessional care.
Methods: Pharmacy students and family medicine residents were invited to participate in an IPE experience during their medicine rotation, in which student-resident pairs worked collaboratively on patient care for a block rotation. We used a Student Perceptions of Physician-Pharmacist Interprofessional Clinical Education Instrument (SPICE-2) survey instrument and included an opportunity for open comments by participants. We performed statistical analysis using paired t tests. 
Results: We observed statistically significant changes (P<.05) in four of the 10 survey items for pharmacy students and two out of 10 in family medicine residents. Narrative comments provided by both students and residents were positive regarding the IPE experience. 
Conclusion: This pilot provides preliminary evidence to support an IPE care model that integrates pharmacy students by pairing them with family medicine residents on an inpatient adult family medicine teaching service. Implementation of a paired-IPE model changed both professions' perception of their roles within the team and appreciation of training requirements. Larger studies could be done to further evaluate the outcomes of this and similar models.

Emerging urban rights
Authors: Gnecco Quintero Carlos Alberto
Published: May 2022

Los derechos urbanos emergentes se plantean como una respuesta a la crisis que actualmente viven las ciudades. El mundo dejó de ser rural y ahora es urbano. El modelo urbano imperante es depredador e inhumano. La actual crisis de la covid-19 revela una serie de problemas sistémicos en la ciudad. Los derechos humanos tradicionales no dan respuesta a la emergencia urbana que se vive en las calles. La gran mayoría de ciudadanos habitan en barrios informales, sin agua, sin servicio de gas, sin saneamiento básico, sin infraestructuras adecuadas, sin electricidad. Viven en espacios hacinados, en una ciudad que no garantiza derechos urbanos. Así las cosas, en la ciudad se reclaman una nueva generación de derechos. Nuevos colectivos sociales o ciudadanías en emergencia piden que la ciudad tenga unos mínimos básicos que permitan dignificar los entornos urbanos. En este sentido, puede ser una solución aplicar la tesis de los derechos emergentes a derechos en el contexto urbano. Así como se ha creado nuevas categorías, como son los derechos ecológicos, los derechos de solidaridad, los derechos republicanos, se propone plantear los derechos urbanos emergentes como categoría. Este artículo de revisión es un aporte en esa línea.
The rights of nature in colombian and indian case-law
Authors: Bagni Silvia
Published: May 2022

La naturaleza ha sido, por largo tiempo, una voz no escuchada por el derecho. Sin embargo, desde los setenta del siglo pasado, la comunidad internacional ha empezado a cambiar de mentalidad y considerar el ambiente como un objeto de interés jurídico. La crisis ambiental que está amenazando el planeta, nuestra casa común, y nuevos enfoques epistemológicos basados en la earth jurisprudence han favorecido la emersión del concepto de “derechos de la Naturaleza”. A nivel constitucional, han sido reconocidos en la Constitución de Ecuador en 2008. Además, muchos otros países han aprobado leyes que atribuyen personalidad jurídica a ríos, glaciares, animales, etc. El artículo compara la reciente jurisprudencia colombiana e indiana que ha reconocido componentes naturales como sujetos de derechos.
El derecho emergente a la seguridad vital de las mujeres y su aplicación teórica y práctica en procesos de reforma del sector de la seguridad en posconflicto
Authors: Miralles Crespo Nora
Published: May 2022

The progressive central role of emerging human rights in post-conflict contexts has materialized in a normative and doctrinal specification of the right of women to a life free of violence, in connection with the dimensions of physical and personal security proposed by Human Security. Thus, the need to reform or transform the institutions that provide security to include the gender perspective in them has become increasingly important in peacekeeping missions, especially after the adoption of United Nations Security Council Resolution 1325 on Women, Peace and Security, in October 2000. This article aims to shed light on the security perspectives, policies and practices operating in post-conflict Security Sector Reform processes and on the extent to which these have been permeated by gender focus and by the contributions of anti-war feminism and of Feminist Security Studies. To this end, the document assesses the operationalization of the United Nations mandate on Security Sector Reform during the transition process of Timor Leste (1999 to 201), and the deployment of tools for the promotion of equality between men and women and the eradication of gender and sexual violence, as well as its results.

Published: May 2022

In this study, gallic acid was separated by triphenylphosphine oxide in
the presence of conventional solvents. Triphenylphosphine oxide is an
organophosphorus extractant and highly selective towards carboxylic
acids. Reactive extraction results were compared with physical
extraction results. The extraction efficiencies reached up to 61, 76,
86, 67, and 84 % in the presence of triphenylphosphine oxide with oleyl
alcohol, dimethyl adipate, isobutanol, methyl isopropyl ketone, and
methyl ethyl ketone, respectively. Further, the number of theoretical
units and the solvent to feed ratio were calculated for the practical
design of a liquid-liquid extraction column. Roughly 2 to 4 theoretical
units were calculated to meet the targeted extraction efficiencies.
Gradient boosting algorithm showed a good performance to predict the
results. This study is the first to investigate the reactive extraction
of gallic acid by triphenylphosphine oxide, and include fundamental
information for the recovery of gallic acid.
Investigation of electrohydrodynamic calculations
Authors: Boskovic Stefan , Karac Aleksandar , Vrhovac Slobodan , Belic Aleksandar , Bugarski Branko
Published: May 2022

A perfect dielectric model was incorporated into the OpenFOAM? software and used for investigation and, possibly, improvements of electrohydrodynamic calculations. Two different sets of numerical simulations were analyzed, in which two different fluids were present. The first set was one-dimensional, while in the second, a drop of one fluid was surrounded by the other fluid. It is shown that oscillations and possible artificial generation of a curl of the electric field strength can be observed at applying certain expressions or calculation strategies, which can be thus abandoned. Usage of dynamic meshes, at least those present in the used software, and of limiters for the gradient of the electric field strength can lead to large numerical errors. It is also shown that usage of certain cell face values could improve the results. An electric Courant number was derived by dimensional analysis, and it could be suggested for future calculations. Conclusions made in this paper are expected to be transferable to other more complicated models.
Co-singing in Families Living with Dementia1
Authors: Waage Helene
Published: May 2022

The incidence of dementia is increasing rapidly, and a growing number of persons with dementia live in their private homes, even in stages of severe dementia. Therefore, persons with dementia and their relatives could benefit from supportive strategies to maintain communication and meaningful activities as their daily lives change due to the condition. Many people have had considerable singing experiences throughout their lives. Thus, low-threshold, flexible daily life singing activities for persons with dementia and their relatives could be based on their own singing competences and background. However, most existing research on singing and music for this target group, outside institutionalised healthcare settings, involves music therapists instructing relatives on how to apply individualised music programmes.
This article suggests a supplemental approach, and the term “co-singing” is proposed to describe such a practice. Singing in the context of families affected by dementia is seen in relation to different, though overlapping theoretical perspectives: health musicking, communicative musicality, dementia and memory, and the polyvagal theory. Within this context, the concept of co-singing highlights the relational aspects of singing, also outside a professional therapeutic or institutionalised context of music and dementia. Thus, “co-singing” provides a supplement and fills a gap between “singing” in general and “caregiver singing” or “care-singing”. Co-singing in families – even when facing severe dementia – can enhance communication and interaction through an entangled process of neuropsychological co-regulation and implicit memories and skills.
Konstitueringen av en semiprofesjonell jentekorpraksis: En retrospektiv empirisk studie om frambringelsen av varige kulturelle verdier i et jentekor

Published: May 2022

Among children and young people, girls in particular sing in choirs. Some girls’ choirs can refer to a particularly high artistic level that falls into the sub-category semi-professional choirs or «elite choirs». One might say that Sandefjord girls’ choir (1956–1997) belonged to this category. This chapter is based on material from a survey among Sandefjord girls’ choir former members, qualitative interviews and supplementary sources based on the following research question: How is a girls’ choir practice constituted over time, and which values in the social practice emerge as lifelong learning for the choristers? In Bourdieu’s cultural sociology, values are understood as accumulated resources or capital. The purpose of the study is to contribute to the development of knowledge about the values which generates in the semi-professional girls’ choir culture as a specific practice in the field of music. Implicitly, this involves a contextualization of the girls’ choir practice in historical time and in geographical place. The study shows that «vocal-musical», co-singing and educational values are most prominent in girls’ choir practice, also as a foundation for lifelong learning. Through this, habitus emerge as a specific kind of «girl’s-choir-singers’ habitus». Despite significant structural changes since the 1950s and into the present, both in the field of music and in society in general, it is clear that new generations of choristers have been regulated and shaped through a reproduction of the values that exist in the social practice.
Rethinking Motivation in Choir Participation: Proposing a Contextual Model of Motivation
Authors: Eiksund Øyvind Johan
Published: May 2022

Choir singing is a worldwide, multifaceted phenomenon, thus, to some extent choral research can be described as a multidisciplinary field. However, research on motivation in choir participation does not show the same multifaceted diversity, which would create opportunities for expanding present discourse. The aim of this chapter is to rethink the notion of motivation in choir participation by emphasising the importance of cultural and social contexts, and by doing this, offer a deeper and more nuanced understanding, which also includes sociological, cultural, and emic bottom-up perspectives. The data for this study were generated in Sunnmøre, Norway, and includes twelve interviews, notes from participant observation periods with four choirs, and a larger online survey. Through a “near-to-the-data” analysis the findings are expressed through a contextual model of motivation, where a range of motivational factors were sorted according to whether they are perceived to be central or peripheral to the informant. The model proposes connections and dynamics providing insight into how motivation may evolve both individually and collectively, and offers alternative ways of speaking and thinking, creating opportunities for changing how we experience and do choral work and research.
Using the ‘Wisdom of the Crowd’ to Innovate in Health Professions Pre-Registration Curriculum Design
Authors:   , St. John-Matthews Janice
Published: May 2022

This thesis's subject of inquiry is the role of crowdsourcing as a technological tool to enable stakeholder contribution in health professions education curricu-lum design, specifically the application of crowdsourcing in a local periodic di-agnostic radiography degree programme revalidation. The stakeholder groups the research focused on were students, patients, and the public. Informed by a narrative literature review of crowdsourcing in health professions education, the research aimed to establish if crowdsourcing could be deployed to support the involvement of these stakeholders when designing a pre-registration diagnostic radiography programme at a single Higher Education Institute. Due to the lim-ited evidence uncovered on the topic and the identified studies mapping to the 'systems' aspect of Jurgen Habermas's theory of communicative action, this lens was applied to this study. A pragmatic, action research approach using an embedded mixed methods design afforded the ability to explore how the crowdsource would need to be designed to enable students, patients, and pub-lic participation. Methodically applying Wadsworth's complete cycle questions and using the critical learning from each cycle for the preceding cycle sup-ported understanding of how the tool could be employed in the curriculum de-sign process. The final product of these 'reflect and refine' activities was a set of six (ICARUS) design principles that could be applied by other health profes-sions educators seeking to use crowdsourcing in this way. Findings also demonstrated that people did engage with the opportunity, and those that joined represented a diverse demographic. Moreover, following a review of con-temporary radiography education literature, crowd ideas were included in the updated curriculum programme specification. The impact of Covid-19 on the work and how the increasing use of digital data collection tools during this time has amplified the interest in crowdsourcing is discussed. The work recognises several limitations alongside recommending areas for future research.
Misdirection – Magic, Psychology and its Application
Authors: Kuhn Gustav , Kingori Patricia , Peeters Grietens Koen
Published: May 2022

The art of magic relies on deception and illusions to create human experiences that appear impossible.  Misdirection lies at the heart of this deceptive art, and yet there is little consensus as to what this concept aims to describe.  The concept of misdirection is not limited to magic, and its principles are applied to wide aspects of our lives (e.g., politics, public health, marketing).  In recent years, scientists have started to examine the psychological mechanisms that underpin misdirection and new theoretical frameworks have been developed to help understand the concept itself.  This paper will provide two different perspectives on misdirection.  In the first section we will discuss its use in magic and examine some of the key features involved in using misdirection to create magical illusions.  This section will examine some common misconceptions of misdirection.  The second section will provide a psychological perspective that discusses the key psychological mechanisms that are involved in misdirection (perception, memory, reasoning).  This paper aims to provide a clearer understanding of how misdirection is used in magic which can serve as the basis for its use in other domains, such as public health.

South Solok Regency is prone to flooding and the impact is felt by the community. Therefore, the government needs to take measures in the form of disaster risk reduction. But nature does disaster risk reduction, problems often occur which result in efforts to reduce disaster risk not maximally. So the purpose of this study is to describe the disaster risk reduction strategies implemented by the government and the factors that influence the government in reducing disaster risk. The research method used is a qualitative approach with descriptive techniques and analysis techniques using SWOT analysis. The results found are firstly that the district government has not optimally implemented disaster risk reduction due to insufficient budget and lack of facilities and infrastructure. Second, community participation is lacking in disaster risk reduction activities. The three communities do not protect the surrounding environment. So the government should use a strategy, first asking for financial assistance from the central and provincial governments. In addition, the business world should also provide grants to district governments to optimize disaster risk reduction activities and complete inadequate facilities and infrastructure. Second, approaching the community by visiting their homes so that the community can actively participate in disaster risk reduction. The three governments make regulations on protecting the environment.

Based on the research studies the shaft power was determined versus the containership speed for the hulls with the original and modified bow shapes. Conclusion. Switchover to lower speeds combined with optimization and modernization of bow shapes will bring a possible reduction of shaft power and, accordingly, less fuel consumption and carbon dioxide emissions by about 40 %.
Comparative resistance & seakeeping analyses of warship displacement monohulls, when modified to inverted bow forms from conventional bow
Authors:   Directorate of Naval Architecture, Integrated Headquarters – Ministry of Defence (Navy), New Delhi, India, Talukdar Biplabananda
Published: May 2022

The paper primarily includes comparative performance analyses (i.e. changes/improvements in Resistance & Seakeeping characteristics) of a warship monohull (with a conventional bow), operating in displacement mode, when modified to various inverted bow forms. The work presented in the paper has been inspired by various research works already published worldwide and available literature regarding the same. For the research problem, a naval warship hull with conventional bow was taken as the benchmark and was suitably modified to a number of different hull form variants with inverted bow forms (i.e. Axe bow, Uistein X-bow, Sword bow and typical Inverted Bow forms), preserving sufficient characteristics for a meaningful comparison, yet making enough changes in various hull form parameters to obtain sufficient variations in hydrodynamic characteristics. Based on the analyses, it was possible to undertake multistage screening of the hull variants, as well as to obtain a considerable overview which enabled to make definitive comments regarding the research questions formulated.

Authors:   St. Petersburg State Marine Technical University, St. Petersburg, Russia, Mironov М.Yu.
Published: May 2022

Object and purpose of research. The study focuses on management of dynamic parameters of structures, the load on which has unsteady character in accordance with a given frequency spectrum. Based on the earlier obtained [8, 15] matrix relations of sensitivity analysis, effective design iteration algorithms, which satisfy Kuhn–Tucker optimum conditions, are developed and implemented in software. Materials and methods. The methods used are a displacement method version of the beam finite-element technique, analytical and semi-analytical methods of taking a derivative with respect to frequencies, shapes as well as unsteady displacements of structure integrally averaged in space and time, methods of simple iterations with relaxation smoothening, methods of linearization of recurrent relations of optimality conditions and reduction of conditional minimization problem to unconditional problem using Lagrange factors. Main results. For FE beam model with a large number of finite elements, minimization mass problems are solved at restricted integral norm of deflection for various unsteady excitation at a given time interval. Comparison of optimization procedures are made for accuracy and efficiency using direct implicit differentiation of difference scheme and normal mode method for response. Conclusion. Similar results are obtained by different methods of calculating the unsteady response and performance of sensitivity analysis. Efficient management of the mass and stiffness distribution is demonstrated with a relatively high gain in isoperimetric formulation.

Published: May 2022

Background. Burn surgery is associated with high blood loss to both the donor and recipient site. Although various techniques for reducing intraoperative blood loss have been described, topical adrenaline and adrenaline infiltration have significantly reduced blood loss. The present study compared blood loss to the donor site and acute cardiovascular effects (such as heart rate/ HR and blood pressure/ BP), by using adrenaline infiltration and topical adrenaline while harvesting the skin graft in the same patient, but in a different place. Materials and Methods. It is a prospective study that included 50 patients, all undergoing skin graft harvesting using method 1 and local adrenaline - method 2, in different locations. Blood loss and acute cardiovascular effects were assessed and compared between two methods. Results. Blood loss at the donor site is significantly lower in adrenaline infiltration compared to topical infiltration (4.7±0.6 ml vs 10.4±1.2 ml, p<0.001). Compared to baseline, the mean increase in HR and BP was significantly higher after adrenaline infiltration than topical adrenaline, but for a short period of time. Changes in HR values were larger than in BP. Conclusions. Our study showed that adrenaline infiltration was better than topical adrenaline in conserving blood loss, but acute cardiovascular effects (increased BP and HR) were greater after infiltration, being clinically insignificant and requiring no treatment.

Published: May 2022

Background. During the COVID-19 pandemic, access to health care and early detection / treatment of cancers were severely affected. This is a pathological study comparing the involvement of lymph nodes in breast carcinomas before the onset and during the current pandemic. Methods. A retrospective study was conducted on 30 patients with breast carcinomas (15 from January to March of 2019, and 15 from January to March of 2021), who were treated both by surgical excision of the tumor and by resection of the lymph nodes. Histopathological examination of the nodes was performed to detect malignant metastasis, and the average rate of lymph node positivity was calculated. Results. Lymph node metastasis was observed in 8 patients in 2019 and 10 patients in 2021. The average node positivity rate was significantly higher in 2021 than in 2019. During the covid-19 pandemic, there was a significant delay in the presentation of patients who developed symptoms of malignancy to the physician. This led to a delay in diagnosis and thus to the treatment of advanced malignancies, which caused metastases in the regional lymph nodes. Conclusion. Patient awareness should therefore be improved to ensure early presentation and reporting of symptoms. Surgeons must also carefully explore the dissecting field, to ensure that all lymph nodes involved are resected, thus avoiding recurrence and improving the overall patient’s prognosis.

In this study, we aimed to compare complication rates and fluoroscopy exposure time, as well as to analyze the functional results of percutaneous K-wire fixation and K-wire fixation with mini-open techniques in pediatric distal radius fractures. Materials and Methods. In this retrospective design study, one-hundred patients with completely displaced fracture of the distal radius were evaluated in terms of demographic data, radiological and functional evaluations, fluoroscopy exposure time, and complications. In Group 1, 50 patients were treated by closed reduction and percutaneous K wire application. In Group 2, 50 patients were treated with close reduction and K-wire fixation using a mini-incision. Results. There were no statistically significant differences between the two groups in terms of age, fracture degree, reduction degree, and follow-up duration. We found the fluoroscopy time and redisplacement rate were significantly lower in group 2. We did not notice tendon irritation and neuropraxia complications in any of the patients in group 2. We observed good functional results and no malalignment in both groups. Conclusions. The mini-open incision technique had lower complication rates and fluoroscopy durations. Based on the results of this study, K-wire fixation with the mini-open technique may be recommended as an alternative method for pediatric distal radius fractures.

Objectives. Diabetic foot ulcer (DFU) is one of the most important and common complication of type 2 diabetes mellitus (T2DM). A new therapy, consisting of intralesional administration of human recombinant epidermal growth factor (hrEGF), has been suggested to accelerate wound healing and prevent amputations. The effect of hrEGF on DFU treatment was investigated in this study. Materials and Methods. 20 patients with DFU were included in this study, all of whom were receiving insulin treatment for T2DM. In addition, they received intralesional therapy with a dose of 75 μgr of hrEGF, three times a week. Results. In 18 patients, complete granulation response was achieved in approximately 3,3 weeks. There were 2 cases of recurrence at 6 months after EGF treatment. Between 6 and 12 doses of epidermal growth factor were used for this study. The most common side effects were tremor, chills, pain and burning at the site of administration. Conclusions. Our study shows that intralesional administration of hrEGF in T2DM can prevent amputations in DFU and also accelerate wound healing. Thus, intralesional application of hrEGF should be an option for standard care, as a second line of treatment (given its cost-effectiveness) when appropriate.

The combination of lichen planus and lupus erythematosus is rare: the number of overlap syndrome cases described in the world literature does not exceed 50. The clinical picture of the overlap syndrome is variable: patients have discoid lesions of lupus erythematosus and typical flat-topped polygonal papules of lichen planus, as well as joint manifestations in the form of livid-red plaques with central atrophy and superficial desquamation. Laboratory testing reveals positive antinuclear antibody. The histopathological picture is characterized by a combination of histological signs of lichen planus and lupus erythematosus. In some cases, clinical and immunological signs of systemic lupus erythematosus are found in patients with the overlap syndrome. We describe two cases of lichen planussystemic lupus erythematosus overlap syndrome.
Going Hybrid: Traditional versus Hybrid Family Interaction Classes
Authors: Stolz Heidi E. , Green Meagan
Published: May 2022

Hybrid teaching, also known as mixed-mode instruction, occurs when part of a campus-based course is moved online. There is limited research on hybrid courses in Human Development and Family Studies (HDFS). This study examines whether delivery mode impacts various student learner experiences and outcomes in an HDFS course and reports on students’ experiences with hybrid learning. Results indicated no delivery mode differences related to perceived course knowledge, course-related self-efficacy, or student-to-student interaction. However, participants in the hybrid learning mode (n = 33) reported significantly worse experiences and outcomes on all other variables relative to students in the face-to-face section (n = 35). Due to significant baseline differences, more investigation is needed to explore selection effects versus experience effects. Themes related to most and least liked features of the hybrid course are reported and interpreted in light of quantitative findings.

That Dragon, Cancer: What Can a Video Game Teach About Family Illness, Death, and Bereavement?
Authors: Brooks Greg , Haley Laynie , Spellings Tim
Published: May 2022

Illness, death, and bereavement are present in every family’s story, yet not every undergraduate student has experienced them directly. Family Science instructors should seek creative ways to help students understand complex dynamics of families during these crises. That Dragon, Cancer is a narrative video game immerses users in the story of Joel Green and his family during their four-year battle with juvenile cancer. We present findings of a qualitative study of undergraduate students who played That Dragon, Cancer during a course module on death and bereavement. Participants reported that the game was a unique learning experience that illustrated course concepts effectively. We discuss possible barriers to the use of video games in the classroom and give recommendations for overcoming them.
Processes Linking Mothers’ Perceptions of Relationship Satisfaction with their Partner, Coparenting, and Parenting to Children’s Competence and Behavior Problems
Authors: Oh Wonjung , Song Seowon , Niehuis Sylvia
Published: May 2022

Guided by family systems and multi-level complexity perspectives, this study examined dynamic family processes linking mothers’ perceived relationship satisfaction with their partner, coparenting (cooperation, conflict, and triangulation), and harsh parenting to children’s perceived competence and social acceptance, as well as behavior problems. The sample consisted of 61 dyads of mothers and preschool-age children. A path model revealed that low levels of coparenting conflict was directly associated with positive self-perception (greater perceived competence and social acceptance) in children. Mothers’ greater reported relationship satisfaction was also directly linked to children’s positive self-perception and to lesser behavior problems. In contrast, mothers who experienced greater coparenting triangulation with their partners reported harsher parenting, which in turn contributed to children’s behavior problems, supporting the spillover hypothesis. Additional findings highlight specific links between greater maternal relationship satisfaction with their partners, lesser coparenting conflict, and greater social competence in children.
