Clown Nose: A Rare Hypopharyngeal Cancer Metastasis
Authors: Lopes Alexandre Pedro , Matos Ricardo , Marques Ana , Silveira Helena , Santos Marques Pedro , Pinto Moura Carla
Published: January 2022

Cutaneous metastases from squamous cell carcinomas of the head and neck region are uncommon, and their location at the nasal tip is exceptionally rare. A patient, previously treated with surgery and chemoradiation for a hypopharyngeal squamous cell carcinoma, developed several red nodular skin lesions at the nasal tip. Biopsy revealed cutaneous metastasis from the primary tumor. This manifestation was previously described as a “clown nose,” given their appearance and location. Skin lesions should raise suspicion of malignancy, despite their location at uncommon places, particularly in patients with previous diagnosed cancer. Clinicians must be aware that metastases from head and neck cancer can present as a “clown nose.”

Authors: Diaz Valen R. , Albritton Tashuna , Katague Marina , Dancy Victoria , Breny Jean M. , Kershaw Trace
Published: January 2022

Relationship strain or dissolution between new parents can affect the co-parenting relationship and parenting engagement. The purpose of this study was to evaluate the effect of a relationship-strengthening intervention on parenting behaviors among adolescent couples. Data from a pilot randomized control trial conducted with predominantly Black and Latino couples were analyzed using repeated measures analysis of variance. Observed intervention * time effects and intervention * time * gender effects were not statistically significant, but had small to moderate effect sizes. Intervention couples demonstrated increased parenting sense of competence compared to control couples. Gender differences in intervention effects were observed for both parenting experiences and parenting engagement. Given the pilot nature of the study, these findings provide preliminary evidence of the effectiveness of this couple-based intervention for improving parenting outcomes. Future research should assess the intervention in a larger sample and leverage technology-based approaches as methods for content delivery.
Can optimized model-based iterative reconstruction improve the contrast of liver lesions in CT?
Authors: Oppenheimer Jonas , Bressem Keno Kyrill , Elsholtz Fabian Henry Jürgen , Hamm Bernd , Niehues Stefan Markus
Published: January 2022

Background

Computed tomography is a standard imaging procedure for the detection of liver lesions, such as metastases, which can often be small and poorly contrasted, and therefore hard to detect. Advances in image reconstruction have shown promise in reducing image noise and improving low-contrast detectability.

Purpose

To examine a novel, specialized, model-based iterative reconstruction (MBIR) technique for improved low-contrast liver lesion detection.

Material and Methods

Patient images with reported poorly contrasted focal liver lesions were retrospectively reconstructed with the low-contrast attenuating algorithm (FIRST-LCD) from primary raw data. Liver-to-lesion contrast, signal-to-noise, and contrast-to-noise ratios for background and liver noise for each lesion were compared for all three FIRST-LCD presets with the established hybrid iterative reconstruction method (AIDR-3D). An additional visual conspicuity score was given by two experienced radiologists for each lesion.

Results

A total of 82 lesions in 57 examinations were included in the analysis. All three FIRST-LCD algorithms provided statistically significant increases in liver-to-lesion contrast, with FIRSTMILD showing the largest increase (40.47 HU in AIDR-3D; 45.84 HU in FIRSTMILD; P < 0.001). Substantial improvement was shown in contrast-to-noise metrics. Visual analysis of the lesions shows decreased lesion visibility with all FIRST methods in comparison to AIDR-3D, with FIRSTSTR showing the closest results ( P < 0.001).

Conclusion

Objective image metrics show promise for MBIR methods in improving the detectability of low-contrast liver lesions; however, subjective image quality may be perceived as inferior. Further improvements are necessary to enhance image quality and lesion detection.
Experimental verification of predicted capability of a wind turbine drivetrain test bench to replicate dynamic loads onto multi-megawatt nacelles
Authors: Giguère Philippe , Wagner John R
Published: January 2022

A total of 27 test profiles from the IEC 61400-1 design load cases were tested using a 7.5-MW wind turbine drivetrain test bench and two multi-megawatt wind turbine drivetrains. Each test profile consisted of simultaneous vertical, lateral, and longitudinal forces, yawing and nodding bending moment, and rotational speed. These test-bench inputs were compared with the forces, bending moments, and speed that were applied to the wind turbine drivetrains to quantify the test-bench tracking error. This tracking error was quantified for a range of ramp-rate limits of the yawing and nodding bending moments. The experimental results were compared with predictions from an evaluation method for the capability of wind turbine drivetrain test benches to replicate dynamic loads. The method’s predictive capability was found to be sufficient for the goal of early screening and its formulation is applicable to any wind turbine drivetrain test bench and drivetrain design.
Augmentation of Distal Biceps Tendon Ruptures With the Lacertus Fibrosus: A Biomechanical Study in a Tendon-Deficient Model
Authors: LeVasseur Matthew R. , Cusano Antonio , Mancini Michael R. , Uyeki Colin L. , Pina Matthew J. , Obopilwe Elifho , Caputo Andrew E. , Mazzocca Augustus D.
Published: January 2022

Background:

Chronic distal biceps tendon ruptures may require tendon graft augmentation secondary to tendon attrition or retraction. The lacertus fibrosus is a local, cost-effective graft that can be used to supplement reconstruction.

Purpose:

To compare the biomechanical strength of distal biceps tendon repairs with and without lacertus fibrosus augmentation in a tendon-deficient cadaveric model.

Study Design:

Controlled laboratory study.

Methods:

Sixteen fresh-frozen matched cadaveric pairs of elbows were randomized into 2 groups: (1) standard distal biceps tendon repair and (2) tendon-deficient (50% step cut) repair with lacertus fibrosus augmentation. All repairs were completed using an oval bone trough and 2 double-loaded No. 2 braided nonabsorbable sutures in a locked Krackow fashion tied over a lateral bone bridge. For the lacertus augmentation group, the lacertus was wrapped circumferentially in a tubular fashion around the tendon to restore the native size and incorporated into the Krackow suture. All specimens underwent cyclic loading and then were loaded to failure. Displacement, stiffness, load to failure, and mode of failure were recorded.

Results:

The standard repair and lacertus augmentation groups had similar displacements on cyclic loading (1.66 ± 0.62 vs 1.62 ± 0.58 mm, respectively; P = .894). The stiffness was significantly greater for the standard repair group (21.3 ± 2.5 vs 18.5 ± 3.5 N/mm; P = .044). Both groups provided excellent mean peak load to failure strengths, despite the standard repair group having significantly greater strength (462.4 ± 140.5 vs 377.3 ± 101.1 N; P = .022). The primary mode of failure in the standard repair group was fracture at the bone bridge (n = 5/8) compared with suture pullout (n = 4/8) in the lacertus augmentation group.

Conclusion:

Lacertus fibrosus augmentation of a tendon-deficient biceps repair was less stiff and had lower mean load to failure compared with repair of the native tendon in this cadaveric model, but these values remained biomechanically acceptable above critical thresholds. Consequently, lacertus fibrosus augmentation is a viable option for chronic distal biceps tendon ruptures with tendon attrition.

Clinical Relevance:

Chronic distal biceps tendon ruptures may require autograft or allograft reconstruction secondary to tendon scarring, shortening, attrition, and degeneration. The lacertus fibrosus is a cost-effective and low-morbidity local autograft that can be used to augment repairs.

Published: January 2022

The majority of the melanocytic neoplasms are considered malignant and highly metastatic. However, a subset of the melanocytic tumors has a more favorable prognosis and the identification of precise prognostic markers for this neoplasm may be useful to guide treatment. The collagen architecture and density have been shown to correlate with tumor progression in human breast cancer and canine mast cell tumors. The purpose of the present study was to investigate the prognostic value of the intratumoral collagen index (ICI) as an indicator of postsurgical survival and its relation with other prognostic markers for canine oral melanomas (OMs). Twenty-two cases were tested for intratumoral collagen density using Masson's trichrome stain and morphometry. No differences were found between dogs regarding survival. The ICI was not correlated with proliferative activity or nuclear atypia. The results presented herein indicate that the quantity of intratumoral collagen in canine OMs is not an efficient indicator of postsurgical survival. Complementary studies about the expression and activity of enzymes that are capable of degrading extracellular matrix (ECM) components are necessary.
Dennis Showalter and the study of the First World War
Authors: Neiberg Michael
Published: January 2022

Dennis Showalter’s influence on the scholarship of the First World War is unmatched among American historians. His work is especially important for two reasons. First, it studies the German Army using primary sources and original research, a particularly valuable contribution given the mythic and just plain false associations that many amateur scholars place on the German military. Second, Dennis’s career involved long stretches of teaching cadets and military officers. His work thus combined an appreciation of the problems of the past with the challenges of the present day. The second half of this essay renders homage to that tradition by examining patterns in Dennis’s writings of the First World War that remain relevant to an understanding of war in our own time.

Do Trade and Poverty Cause Each Other? Evidence from BRICS
Authors: Rahman Mohd Nayyer , Rahman Nida , Turay Abdul , Hassan Munir
Published: January 2022

Any two variables that are observable have one or the other form of relationship. This is particularly a statistical relationship. But for a statistical relationship to be cause and effect, a theoretical relationship is important. The theoretical relationship can be quantified to search for the evidence of causality. The possible outcomes can be no causality, unidirectional causality, or bidirectional causality. The present study aims at searching for evidence from BRICS countries regarding trade causing poverty or vice versa. Applied econometrics approach is used in the study. Panel econometric techniques have been employed to identify presence/absence of causality between the variables. Apart from this, the study also uses equality of means to identify whether trade and poverty proxies are symmetrical or asymmetrical. The study finds no causal relationship between trade and poverty for BRICS countries except that poverty headcount at $3.2 per day causes trade balance. With respect to the impact on the GINI index, lowest 10 percent income share and poverty headcount ratios are integral to reduce the inequality in the BRICS countries.
Exploring Black Women’s Pathways to Motherhood Within a Reproductive Justice Framework
Authors: Leath Seanna , Wright Patrice , Charity-Parker Bianka , Stephens Erica
Published: January 2022

Amidst the increasing push to address racial disparities in maternal health equity, fewer studies have considered Black women’s perspectives on their needs, concerns, and priorities regarding family planning care. Such evidence might help address the lack of support and information that many Black women report in patient–provider encounters, and broaden empirical knowledge on the contextual factors that influence Black women’s reproductive decisions. In the present qualitative study, we explored Black women’s pathways to motherhood within a reproductive justice framework. We drew on individual, semi-structured interview data from 31 Black mothers (25–50 years, Mage = 35 years) across the United States. Using consensual qualitative research methods, we elaborated on three themes: (1) intentional family planning, (2) unintended pregnancy, and (3) othermothering. The findings challenge deficit-based stereotypes of Black mothers’ reproductive choices and illuminate how health practitioners can facilitate humanizing conversations that prioritize Black women’s family planning goals and decision-making.

Authors: Brooks Spirit D. , Braun Steven M. , Prince Dan
Published: January 2022

Background: Research highlights how high school near-peer mentors (HSNPMs) in outdoor school settings enhance younger students’ programing experiences. Through this engagement, HSNPMs’ critical consciousness (CC) of equity in outdoor and experiential education (OEEE) expands. Purpose: This article explores how HSNPMs develop CC of environmental and social justice in OEEE. Methodology/Approach: We used critical ethnography to understand how near-peer mentoring programing associated with equity, diversity, access, and inclusion (EDAI) develop CC, in OEEE. Findings/Conclusion: Intentionally developed training and curricula rooted in social justice education facilitate CC development. This training includes staff's facilitation of equity discussions and support of high school students’ EDAI-related awareness, skills, and behaviors. Implications: HSNPMs contribute to EDAI in OEEE programs. We recommend including HSNPMs in staff training, program improvements, and planning activities.
Bilateral intraocular and lung involvements associated with Nasal NK/T-cell lymphoma
Authors: Wang Luping , Jia Mei , Zhang Ruxiang , Casalino Giuseppe , Chakravarthy Usha , Wang Yanling
Published: January 2022

Background

To report a rare case of nasal natural killer/T (NK/T) cell lymphoma with bilateral intraocular and lung metastasis and to further describe the clinical features of intraocular manifestations.

Case presentation

A 54-year-old man presented with a 3-month history of left nasal congestion, and bilateral vision impairment of one week duration. Subsequent maxillary computed tomography (CT) and multiple biopsies confirmed the diagnosis of nasal NK/T-cell lymphoma. EBV-encoded small RNA (EBER) in situ hybridization revealed EBV infection. A comprehensive ophthalmic examination found lymphoma-associated retinopathy and choroidopathy, which presented as bilateral diverse patterns and retinal detachment. In addition, the chest CT showed multiple scattered nodules in both lungs, and soft-tissue mass in the left hilum with mediastinal and axillary lymphadenopathy. The condition of this patient deteriorated rapidly and he died shortly after diagnosis.

Conclusions

The rarity of secondary ocular NK/T-cell lymphoma makes it challenging to identify these tumors early. Both otolaryngologist and ophthalmologists should be aware of ocular involvement and other secondary manifestations of NK/T-cell lymphoma.
Cry1Ac Protoxin Confers Antitumor Adjuvant Effect in a Triple-Negative Breast Cancer Mouse Model by Improving Tumor Immunity
Authors: Servin-Garrido Roberto Raúl , Ilhuicatzi-Alvarado Damaris , Jiménez-Chávez Ángel de Jesús , Moreno-Fierros Leticia
Published: January 2022

The Cry1Ac protoxin from Bacillus thuringiensis is a systemic and mucosal adjuvant, able to confer protective immunity in different infection murine models and induce both Th1 and TCD8+ cytotoxic lymphocyte responses, which are required to induce antitumor immunity. The Cry1Ac toxin, despite having not being characterized as an adjuvant, has also proved to be immunogenic and able to activate macrophages. Here, we investigated the potential antitumor adjuvant effect conferred by the Cry1Ac protoxin and Cry1Ac toxin in a triple negative breast cancer (TNBC) murine model. First, we evaluated the ability of Cry1Ac proteins to improve dendritic cell (DC) activation and cellular response through intraperitoneal (i.p.) coadministration with the 4T1 cellular lysate. Mice coadministered with the Cry1Ac protoxin showed an increase in the number and activation of CD11c+MHCII- and CD11c+MHCII+low in the peritoneal cavity and an increase in DC activation (CD11c+MHCII+) in the spleen. Cry1Ac protoxin increased the proliferation of TCD4+ and TCD8+ lymphocytes in the spleen and mesenteric lymph nodes (MLN), while the Cry1Ac toxin only increased the proliferation of TCD4+ and TCD8+ in the MLN. Remarkably, when tested in the in vivo TNBC mouse model, prophylactic immunizations with 4T1 lysates plus the Cry1Ac protoxin protected mice from developing tumors. The antitumor effect conferred by the Cry1Ac protoxin also increased specific cytotoxic T cell responses, and prevented the typical tumor-related decrease of T cells (TCD3+ and TCD4+) as well the increase of myeloid-derived suppressor cells (MDSC) in spleen. Also in the tumor microenvironment of mice coadministered twice with Cry1Ac protoxin immunological improvements were found such as reductions in immunosupressive populations (T regulatory lymphocytes and MDSC) along with increases in macrophages upregulating CD86. These results show a differential antitumor adjuvant capability of Cry1Ac proteins, highlighting the ability of Cry1Ac protoxin to enhance local and systemic tumor immunity in TNBC. Finally, using a therapeutic approach, we evaluated the coadministration of Cry1Ac protoxin with doxorubicin. A significant reduction in tumor volume and lung metastasis was found, with increased intratumoral levels of tumor necrosis factor-α and IL-6 with respect to the vehicle group, further supporting its antitumor applicability.
Assessment of Knowledge, Practices, and Challenges of Pharmaceuticals Inventory Control Among Pharmacy Professionals Working in Selected Public Health Facilities of West Arsi Zone, Oromia, Ethiopia
Authors: Jobira Tadesse , Abuye Habtamu , Jemal Awol , Gudeta Tadesse
Published: January 2022

Background:

Good pharmaceutical inventory control enables health facilities (HFs) to provide complete health care by ensuring the availability of safe, effective, and affordable pharmaceuticals and related supplies of the required quality, inadequate quantity, at the required place and at all times. It boosts patients’ trust in the HFs and motivates working staff. However, it needs well-trained and skilled professionals. The aim of the current study was, therefore, assessing knowledge, practice, and challenges of pharmacy professionals conducting inventory control in selected public health facilities of West Arsi Zone, Oromia regional state for the year 2016 to 2018.

Method:

A mixed-methods study design was used to assess pharmacy professionals’ knowledge, skills, and challenges in applying inventory management methods. A semi-structured questionnaire was implemented for quantitative, whereas an open-ended question was employed for key informants (KIs) to explore qualitative data.

Result:

Ninety percent of pharmacy professionals knew about VEN analysis concepts and 70% about ABC analysis. However, none of them had a concept of FSN and XYZ analysis. Among the respondents who knew the concept, 75% had gained knowledge through formal training and 10% of them learned from on-job training. When they asked about the methods of inventory control, 60% responded as they did not hear about it. Of those who said “Yes” on being asked to mention at least 1 method of it, 80% could not able to correctly mention the methods used in inventory control. However, 44%, 62.5%, and 75% of respondents had practiced ABC, VED, and ABC-VED matrix analysis respectively. The challenges that prevented these professionals from practicing pharmaceutical inventory control in their HFs were grouped into price-related, training-related, human resource-related, and managerial-related factors.

Conclusion:

Inventory control is the heart of the pharmaceutical supply system. Without its healthy action, HFs’ goal attainment will not be viable. Problems of sick pharmaceutical inventory control are directly related to a lack of knowledge and appreciation of it by the concerned bodies. The current finding revealed almost all pharmacy professionals included in the study had little knowledge about how to manage their inventories. Managers’ unwillingness to cooperate and facilitate necessary resources prevented the professionals from doing inventory control.
What do Indonesian start-ups communicate during the COVID-19 pandemic?
Authors: Luik Jandy
Published: January 2022

This article aims to explore the media content during the COVID-19 pandemic. It focuses on the pandemic-handling videos released by start-up companies in Indonesia through their official YouTube accounts. As start-ups were also experiencing the impact of the pandemic, one of their biggest challenges was to communicate optimistic messages to the public with the right content and context. Therefore, this article examines the contents of the videos released by start-up companies during the COVID-19 pandemic in Indonesia. Drawing from the data collected between March and December 2020, this qualitative study finds four inspirational media themes: ‘ we all are affected by the pandemic’, the appearance of human values, presenting action taken, and optimistic expressions. Further, this article discusses the arrangement of inspirational statements and acts of empathy, which are predominantly mixed with brand identities and echo the value of gotong royong (mutual assistance).
The impact of perceived relationship to ancestors on the association between self-transcendence and psychopathology: A cross-cultural examination
Authors: Choi Simon Hanseung , McClintock Clayton Hoi-Yun , Lau Elsa , Miller Lisa
Published: January 2022

Self-transcendence has been associated with lower levels of psychopathology. Most studies of self-transcendence have focused on samples of Western participants, and used scales addressing such concepts as self-awareness and feelings of oneness with the larger universe. However, a common Eastern notion of transcendence—perception of ongoing relationships with ancestors—has not been studied. We conducted a cross-cultural investigation of the association between self-transcendence, perceived degree of relationship to ancestors and depression and anxiety in the United States (N = 1499), China (N =  3,150), and India (N = 863). Degrees of perceived relationship to ancestors differed across countries, with the highest rates in India and China, and lowest rates in the United States. Self-transcendence was negatively associated with risks for depression and anxiety in the United States. In India, self-transcendence was also negatively associated with risks for depression and anxiety, and a strong perceived relationship with ancestors had further protective benefit. In China, those with a high level of perceived relationship to ancestors and a high level of self-transcendence exhibited lower levels of psychopathology. Results suggest that measures of relationship to ancestors might be included in future cross-cultural studies of transcendence.

Published: January 2022

In this qualitative exploratory study, we investigated the perspectives of mental health providers in Gaza, Palestine, regarding the primary concerns of their clients who are exposed to low-intensity warfare and structural violence. We conducted qualitative interviews with 30 psychologists, social workers, psychiatric nurses, and psychiatrists providing services to communities in Gaza. Participants were asked to discuss their clients’ most commonly occurring mental health problems, diagnoses, and psychosocial conditions. Thematic analysis identified one superordinate theme (Impact of the Blockade on Mental Health and Quality of Life) and four second-order themes (Concerns about Social Problems, General Concerns about Quality of Life, Concerns about the Mental Health of the Community, and Concerns Related to Children's Mental Health). Participants indicated that the social and political dimensions of mental health and the economic, educational, and health-related consequences of the ongoing blockade of Gaza were the main determinants of psychological burden among their clients. Findings demonstrated the importance of adopting an approach to mental health that includes understanding psychological indicators in a broader framework informed by human rights and social justice. Implications for research and clinical work are discussed, including the role of investments in social capital that may provide individuals with access to resources such as social support, which may in turn promote overall mental health.
The good ol’ days: White identity, racial nostalgia, and the perpetuation of racial extremism
Authors: Reyna Christine , Harris Kara , Bellovary Andrea , Armenta Angel , Zarate Michael
Published: January 2022

A prevailing theme in White nationalist rhetoric is nostalgia for a time when Whites dominated American culture and had unchallenged status. The present research examines a form of collective nostalgia called racial nostalgia and its association with negative intergroup attitudes and extreme ideologies (White nationalism). In Studies 1 and 2, racial nostalgia was associated with higher racial identity, anti-immigrant attitudes, and White nationalism. Study 2 revealed that racial nostalgia was related to extreme ideologies, in part, through perceptions that immigrants and racial minorities posed realistic/symbolic threats. Study 3 manipulated nostalgia using a writing prompt (“America’s racial past” vs. “games of America’s past”) and an identity prime (prime vs. no prime). Racial nostalgia was higher in the racial prompt versus the games prompt condition, regardless of identity prime. Furthermore, there were significant indirect effects of the nostalgia manipulation on support for anti-immigrant policies and endorsement of White nationalism through increased racial nostalgia and its association with perceived threats. These findings show that racial nostalgia can be a maladaptive form of collective nostalgia linked to a sense of loss and threat, and can make people sympathetic to extreme racial ideologies.
“Sincere White people, work in conjunction with us”: Racial minorities’ perceptions of White ally sincerity and perceptions of ally efforts
Authors: Burns Mason D. , Granz Erica L.
Published: January 2022

Social justice movements often consist of both targets of bias (e.g., Black people) and nontarget allies (e.g., White people). However, little is known about what factors shape minorities’ perceptions of allies and their ally behaviors. Across four studies, we investigated Black participants’ perceptions of Whites’ motives to engage in ally behaviors. In Study 1, we found that Black participants perceived nontarget allies as both highly internally and externally motivated, suggesting ally motives may be ambiguous to Black perceivers. Studies 2–4 examined the effect of Black participants’ suspicion of Whites’ motives on perceptions of White allies’ sincerity and support for their ally efforts. As predicted, suspicious Black participants perceived White ally protestors, confronters, and political candidates as less sincere than similar Black targets and, in turn, were less supportive of White allies’ efforts. Discussion focuses on how perceived motives of White allies impact perceptions of allies and their ally efforts.
Education's economic return in multicultural Australia: Demographic analysis
Authors: Foroutan Yaghoob
Published: January 2022

This article focuses on the impact of education as the most important human capital endowment in the context of migration, religion, gender and ethnic identity from a demographic perspective. It presents research-based evidence to address such key research questions as whether and how significantly women's education provides equal benefit in the labour market for individuals, based on their migration status, religion, and ethnic identity. The field of this study is the multi-ethnic and multicultural context of Australia with a wide range of ethnic and religious groups of migrants from throughout the world. Preliminary results show that labour market achievement is positively and significantly associated with the educational attainment of individuals, irrespective of their migration status, religious affiliation and ethnicity. However, more comprehensive analysis from comparative perspectives reveals that the positive economic return of education is higher for natives (compared with migrants), for ethnic migrants from developed regions of origin (compared with those from less developed regions of origin) and for non-Muslims (compared with Muslims). The article provides two plausible explanations for these patterns. The first refers to the lack of recognition of overseas qualifications and to the devaluation of foreign education that particularly applies to ethnic migrants from less developed regions. The second relates to disadvantage through structural discrimination against migrants, particularly when their cultural and religious identity, such as Islamic names and dress codes, are distinctively displayed. In sum, this analysis presents further research-based evidence to go beyond the human capital theory in order to explain more appropriately the economic return of women's education in the context of religion and migration from a demographic perspective.
Reliability of reinforced concrete beams in serviceability limit state via microprestress-solidification theory, a structural health monitoring strategy
Authors: Ghabdian Mohsen , Aval Seyed BB , Noori Mohammad , Altabey Wael A
Published: January 2022

An important and critical area within the broad domain of structural health monitoring, as related to reinforced civil and mechanical structures, is the assessment of creep, shrinkage, and high-temperature effects on reliability and serviceability. Unfortunately, the monitoring and impact of these inherent mechanical characteristics and behaviors, and subsequent impact on serviceability, have rarely been considered in the literature in structural health monitoring. In this paper, the microprestress-solidification creep theory for beams is generalized for the simultaneous effect of linear/nonlinear creep, shrinkage, and high temperature in a reliability framework. This study conducts a systematic time-dependent procedure for the reliability analysis of structures using a powerful nanoscale method. It must be noted that this paper aims to extend the previously developed microprestress-solidification method in a health monitoring reliability-based framework with a close look at a nonlinear creep, parameters affecting creep, and long-time high temperature. A finite element approach is proposed where creep, shrinkage, temperature, and cracking are considered using strain splitting theory. First, the model performance was evaluated by comparing the results with the experimental test available in the literature in the case of creep and shrinkage. Then, the simultaneous effect of creep, shrinkage, and temperature was compared with experimental results obtained by the authors. Reliability analysis was applied to reinforced concrete beams subjected to sustained gravity loading and uniform temperature history in order to calculate exceedance probability in the serviceability limit state. It was found that the exceedance probability of reinforced concrete beams was dependent on the shear span-to-depth ratio. In the serviceability limit state, exceedance probabilities of 0.012 and 0.157 were calculated for the span-to-depth ratios of 1 and 5, respectively. In addition, it was shown that temperature plays an important role in the reliability of reinforced concrete beams. A 4.27-fold increase was observed in the case of moderate to high temperature. Finally, for three different load levels of 40%, 70%, and 80%, the exceedance probabilities were 0.156, 0.328, and 0.527, respectively, suggesting that load level is another key parameter affecting the reliability of reinforced concrete beams. It is thus concluded these fundamental phenomenological studies should be further considered as part of the broad field of structural health monitoring.
The creation of a nudging protocol to support online student engagement in higher education

Published: January 2022

Combining nudge theory with learning analytics, ‘nudge analytics’, is a relatively recent phenomenon in the educational context. Used, for example, to address such issues as concerns with student (dis)engagement, nudging students to take certain action or to change a behaviour towards active learning, can make a difference. However, knowing who to nudge, how to nudge or when to nudge can be a challenge. Providing students with strategic, sensitive nudges that help to move them forward is almost an art form. It requires not only technical skills to use appropriate software and interpret data, but careful consideration of what to say and how to say it. In this article a nudge protocol is presented that can be used in online courses to encourage student engagement with key course resources that are integral to supporting their learning.

Published: January 2022

Knife-coating can confer new properties on different textile substrates efficiently by integrating various compounds into the coating paste. Graphene nanoplatelets (GNP) is one of the most used elements for the functionalization of fabrics in recent years, providing electrical and thermal conductivity to fabrics, later used to develop products such as sensors or heated garments. This paper reports thermoelectrically conductive textiles fabrication through knife-coating of cellulosic fabrics with a GNP load from 0.4 to 2 wt% within an acrylic coating paste. The fabric doped with the highest GNP content reaches a temperature increase of 100°C in few seconds. Besides, it is found out that the thermographic images obtained during the electrical voltage application provide maps of irregularities in the dispersion of conductive particles of the coating and defects produced throughout their useful life. Therefore, the application of a low voltage on the coated fabrics allows fast and effective heating by Joule’s effect, whose thermographic images, in turn, can be used as structural maps to check the quality of the GNP doped coating. The temperature values and the heating rate obtained make these fabrics suitable for heating devices, anti-ice and de-ice systems, and protective equipment, which would be of great interest for industrial applications.

Published: January 2022

Introduction. Although ictal blinking is significantly more frequent in generalized epilepsy, it has been reported as a rare but useful lateralizing sign in focal seizures when it is not associated with facial clonic twitching. This study aimed to raise awareness of eye blinking as a semiological lateralizing sign. Method. Our database over an 11-year period reviewed retrospectively to assess patients who had ictal blinking associated with focal seizures. Results. Among 632 patients, 14 (2.2%), who had 3 to 13 (7 ± 3) seizures during video-EEG monitoring, were included. Twenty-five percent of all 92 seizures displayed ictal blinking and each patient had one to five seizures with ictal blinking. Ictal blinking was unilateral in 17%, asymmetrical in 22% and symmetrical in 61%. The blinking appeared with a mean latency of 6.3 s (range 0-39) after the clinical seizure-onset, localized most often to fronto-temporal, then in frontal or occipital regions. Blinking was ipsilateral to ictal scalp EEG lateralization side in 83% (5/6) of the patients with unilateral/asymmetrical blinking. The exact lateralization and localization of ictal activity could not have been determined via EEG in most of the patients with symmetrical blinking, remarkably. Conclusions. Unilateral/asymmetrical blinking is one of the early components of the seizures and appears as a useful lateralizing sign, often associated with fronto-temporal seizure-onset. Symmetrical blinking, on the other hand, did not seem to be valuable in lateralization and localization of focal seizures. Future studies using invasive recordings and periocular electrodes are needed to evaluate the value of blinking in lateralization and localization.

Objective of Protocol: The primary objective of this protocol is to record the process of conceptualizing a semi-structured interview protocol, training enumerators on the protocol, collecting data, translating findings into English, and analyzing data in English and Bengali, in a study of family socialization among a stateless and conflict-affected population, Rohingya refugees, in Cox’s Bazar, Bangladesh. Research Questions of Study: (1) What are the socialization goals that mothers have for their children, and how do they perceive these goals in relation to their future or current roles as caregivers? (2) What are parents’ experiences with their children’s participation in Humanitarian Play Labs (education/child care provisions in the camps), and what are their perceptions of how their child’s participation in the programs has influenced their child/family? (3) What were the experiences of parents with their children as they migrated from Myanmar to Bangladesh? Design of Study: The design of the study involved a qualitative grounded theory approach based on an analysis of the participants’ responses to a semi-structured interview protocol. Study population: Participants included a purposive sample of 28 mother/father dyads in the Rohingya camps in Cox’s Bazar.
Internal carotid artery anatomy – not always straightforward
Authors: Rudnay Maroš , Rjašková Gabriela , Lehotská Viera
Published: January 2022

Objectives

To present a rare variant of internal carotid artery anatomy.

Methods

Case report presenting CT angiography finding of internal carotid anatomy variant.

Results

We present the case of an unusual origin of the occipital artery from cervical portion of the internal carotid artery as an incidental finding during CT angiography of the carotid arteries. In discussion, we discuss the possible embryological basis, incidence and prevalence of such finding and its possible clinical implications.

Conclusion

One of the specific aspects of carotid arteries is their straightforward anatomy – the cervical portion of internal carotid artery, unlike the external carotid, does not give origin to any branches – this aspect is even used as a highlight for orientation, e.g. during ultrasound examination. However, although rare, variants exist, and sometimes can have clinical importance – in the endovascular access or surgical treatment.

Authors: Dwedar Dahlia
Published: January 2022

Researching Second Language Acquisition in the Study Abroad Learning Environment: An Introduction for Student Researchers (Isabelli-García and Isabelli, 2020) presents an overview of some of the major topics relevant to research on study abroad. This book is intended to be a basic primer for advanced students and beginner professional researchers and serves to provide general orientation on various aspects ranging from language and interactional systems to research gaps in the topic area. The book gives a relatively thorough presentation on some of the scholarly perspectives on study abroad that can be used as a guidebook for anyone who is interested in conducting academic research in the area. While there are some shortcomings, the book does an excellent job of synthesizing some of the major scholarly themes that are relevant to study abroad. Consequently, this is a useful book not only for novel researchers but also for faculty or staff who are interested in organizing university study abroad programs and would like a more thorough background.

Published: January 2022

Objective:

The success of antiretroviral therapy has resulted in the normalization of pregnancy among women living with HIV and a very low risk of perinatal transmission of HIV. Despite these advances, women living with HIV still face complex medical and psychosocial issues during pregnancy. The purpose of this study is to describe experiences of pregnancy and the relevance of social support among women living with HIV in Nordic countries.

Methods:

This qualitative study examined data from pregnant women living with HIV from sites in Denmark, Sweden and Finland from 2019 to 2020. Data were collected in the third trimester via individual interviews using a hybrid, narrative/semistructured format. The transcribed interviews were analyzed using narrative thematic analysis.

Results:

In total, 31 women living with HIV were enrolled, of whom 61% originated from an African country and 29% from a Nordic country. The analysis generated four primary narrative themes: just a normal pregnancy, unique considerations and concerns, interactions with healthcare, and social support. Women living with HIV have a strong desire to have normal pregnancies and to be treated like any other pregnant woman. However, this normality is fragile, and being pregnant and living with HIV does come with unique considerations and concerns, such as fear of transmission, antiretroviral therapy, and the need for specialized care, which are fundamental to the women’s experiences. Interactions with healthcare providers and social support influence their experiences in both positive and negative ways.

Conclusion:

The findings emphasize a sense of normality in pregnancy among women living with HIV. However, pregnancy does come with unique considerations and concerns, which highly influence the women’s experience of pregnancy. Healthcare providers should focus on person-centered care, ensuring continuity and that women living with HIV do not feel discriminated against throughout their pregnancy.
