Published: May 2023

Objective

The objective is to compare the clinical and laboratory characteristics of systemic lupus erythematosus (SLE) patients with and without lupus enteritis (LE) and to identify the factors associated with the occurrence of LE.

Methods

We performed a retrospective, case-control study in hospitalized patients with SLE who were admitted to our tertiary hospital between January 2012 and December 2021. Sixteen LE patients (cases) were matched (1:3 ratio) for sex and birth year with 48 non-LE patients (controls). Univariable and multivariable logistic regression analyses were used to identify the variables associated with LE.

Results

Of 2,479 SLE patients who were admitted to our hospital as inpatients, 16 (0.65%) were diagnosed as having LE. All patients, cases and controls, were of Mestizo ethnicity. SLE was diagnosed simultaneously with the first episode of LE in 10 (62.5%) patients. The median time from SLE diagnosis to the first episode of LE was 7 (IQR 0–78) months. LE patients had a shorter median disease duration [7 (0–78) vs 34 (9.5–79) months], and a significantly longer hospital stay (28.3 ± 15.8 vs 6.5 ± 7.9 days, p < 0.001) than non-LE patients. Most LE patients (93.8%) had concomitant lupus nephritis. LE patients had higher SLEDAI-2K scores than those without LE (20.5 ± 9.4 vs 9.8 ± 10.4, p < 0.001). By multivariable analysis, a higher SLEDAI-2K score (OR 1.10, 95% CI 1.02–1.18; p = 0.015) was independently associated with LE occurrence after adjusting for cutaneous involvement, lymphocyte count, serum creatinine, and serum complement C4. Recurrence was observed in two patients (12.5%), both with a bowel wall thickening > 8 mm. The two patients with large intestine-dominant LE developed intestinal pseudo-obstruction. No patient had life-threatening complications (intestinal hemorrhage, infarction, or perforation), and there were no deaths induced directly by LE itself.

Conclusion

In patients of Mestizo ethnicity, LE occurs during the early course of SLE, frequently is one of the presenting manifestations of SLE, and in most cases, it presents with concomitant lupus nephritis. Higher levels of disease activity at diagnosis were independently associated with LE occurrence and when recurrences occur, they do so in the context of severe wall thickness.
Ten Things You Should Know About Sign Languages
Authors: Emmorey Karen
Published: May 2023

The 10 things you should know about sign languages are the following: (1) Sign languages have phonology and poetry. (2) Sign languages vary in their linguistic structure and family history but share some typological features due to their shared biology (manual production). (3) Although there are many similarities between perceiving and producing speech and sign, the biology of language can impact aspects of processing. (4) Iconicity is pervasive in sign language lexicons and can play a role in language acquisition and processing. (5) Deaf and hard-of-hearing children are at risk for language deprivation. (6) Signers gesture when signing. (7) Sign language experience enhances some visual-spatial skills. (8) The same left-hemisphere brain regions support both spoken and sign languages, but some neural regions are specific to sign language. (9) Bimodal bilinguals can code-blend, rather code-switch, which alters the nature of language control. (10) The emergence of new sign languages reveals patterns of language creation and evolution. These discoveries reveal how language modality does and does not affect language structure, acquisition, processing, use, and representation in the brain. Sign languages provide unique insights into human language that cannot be obtained by studying spoken languages alone.
Hot Markets, Sociocognitive Cues, and New Market Entry in the U.S. Venture Capital Industry
Authors: Lo Jade Y. , Xu Lei , Park Haemin Dennis
Published: May 2023

Investing in sectors that a firm has never invested in before is fundamentally a form of entrepreneurial experimentation and an integral part of wealth creation. We consider how the broader market conditions and sociocognitive cues jointly affect venture capital (VC) firms’ investment decisions in new industries that are unrelated to their past experience. Although VCs are more likely to enter an unrelated new industry when the overall market is hot, they also take sociocognitive cues from their own social contacts and news media. Using the population of U.S. VC investments between 1990 and 2016, we find support for our predictions.
Reader Perceptions of Authorial Voice in Top-Tier Management Journals: The Case of Doctoral Students of Management From Eastern Europe
Authors: Lehman Iga Maria , Sułkowski Łukasz
Published: May 2023

The pressure to publish in scholarly journals has been increasingly pervading doctoral education worldwide and has become a high-stakes activity for any novice writer who wishes to pursue an academic career. In this manuscript, we explore how doctoral students of management from Eastern Europe identify and evaluate authorial voice and compare their perceptions with those of established academics. Perceptions of authorial voice, as manifested in conclusions to six articles published in top-tier management journals, were collected from 24 students and six academics, and analyzed from their responses to a questionnaire. The study highlighted differences in what these groups considered as the rhetorical nature of a convincing authorial voice. The examination of students’ perceptions was expanded through interviews which revealed that for this group, a reader-considerate voice is essential for a text to be convincing. To enable novice academics’ visibility and participation in their discipline’s global discourse community, we provide a compelling case for de-emphasizing the methodological and theoretical soundness (“rigor”) in reporting scholarly work and prioritizing the effective communication of meaningful and practical research (“relevance”). It is also argued that the provision of strategic writing instruction at graduate level will help achieve this goal.
To Treat or Not to Treat? Dilemmas when Deciding on Antineoplastic Treatment in Patients With Far Advanced Cancers
Authors: Paiva Carlos Eduardo , Preto Daniel D’Almeida , de Lima Crislaine , Paiva Bianca Sakamoto Ribeiro
Published: May 2023

Patients with advanced cancers and their oncologists are often faced with difficult treatment decisions, especially when there are borderline situations of expected benefit or increased risk of complications. In this narrative review, we will explore the decision-making process for patients with advanced cancers and provide insights on how to approach this complex task, while didactically dividing the oncologist’s assessments according to a mnemonic rule of the ABCDE of therapeutic decision-making. Part A (advanced cancer) recalls that the rule is to be used specifically for advanced cancers. Parts B (potential benefits) and C (clinical conditions and risks) represents the traditional risk vs benefit scale. In Part D, we discuss ways to identify and understand patients’ desires, values, preferences, and beliefs. The prognostic estimation, from Part E, may function as an “adjust” for the antineoplastic treatment decision-making. Treatment decisions need to be conducted by skilled oncologists, in a patient-centered care, aiming to promote valuable oncology with lower rates of aggressive care.
Association of Pay-for-Performance Reimbursement With Clinical Quality for Minnesota Nursing Homes Residents
Authors: Loomer Lacey , Dauner Kim Nichols , Schultz Jennifer
Published: May 2023

In 2016, Minnesota implemented a new pay-for-performance reimbursement scheme for Medicaid residents in nursing homes, known as Value-Based Reimbursement (VBR). This study seeks to understand whether there is an association between VBR and quality improvement. We use data from 2013 to 2019 including Centers for Medicare and Medicaid Services, Nursing Home Compare, and Long-term care Facts in the US. Using multivariate regression with commuting zone fixed effects, we compare five long-stay and two short-stay clinical quality metrics in Minnesota nursing homes to nursing homes bordering states, before and after VBR was implemented. We find minimal significant changes in quality in Minnesota nursing homes after VBR. Minnesota should reconsider its pay-for-performance efforts.
Introduction: Trauma Literacy in Global Journalism: Toward an Education Agenda
Authors: Ogunyemi Olatunji , Price Lada Trifonova
Published: May 2023

Due to growing evidence of extensive trauma associated with high exposure to traumatizing events, including posttraumatic stress disorder (PTSD) and maladaptive coping strategies among practicing journalists, the drive to prepare journalism students to cope with the emotional and psychological stress of reporting trauma and human suffering has grown significantly among scholars in recent years. This special issue proposes a new pathway to an educational agenda in response to this persistent work-related problem in journalism practice.
Isavuconazonium or posaconazole for antifungal prophylaxis in patients with acute myeloid leukemia
Authors: White Olivia , Kennedy Erin , Huckabee Jordan B. , Rogers Elizabeth , LeBlanc Thomas W. , Dillon Mairead , Li Zhiguo , Hanna Desirae
Published: May 2023

Background

Invasive fungal infection (IFI) prophylaxis is recommended in patients with acute myeloid leukemia (AML) during induction chemotherapy. Posaconazole (POSA) is the recommended agent of choice; however, this medication can be associated with QTc prolongation, hepatotoxicity, and drug-drug interactions. Furthermore, there is conflicting evidence for the role of isavuconazole (ISAV) in this setting as an alternative to POSA.

Objective

The primary objective of this study was to evaluate the use of ISAV prophylaxis for primary IFI prevention in patients with AML undergoing induction. Additionally, the study investigated the use of ISAV trough concentration monitoring and compared these results to the efficacy of POSA therapeutic drug monitoring (TDM). Other secondary objectives included assessing the rates of toxicities associated with either prophylactic agent. This study analyzed the impact these toxicities had on patient outcomes by examining the need to hold or discontinue therapy. The final endpoint considered the efficacy associated with multiple dosing strategies employed at the study institution. Specifically, this included the use of loading doses or foregoing these when initiating prophylaxis.

Methods

This was a retrospective, single-center, cohort study. Patients included in this study were adults with AML admitted to Duke University Hospital between June 30, 2016 and June 30, 2021, who received induction chemotherapy and primary IFI prophylaxis for at least 7 days. Exclusion criteria included patients who received concomitant antifungal agents and patients who received antifungal agents as secondary prophylaxis.

Results

241 patients met inclusion criteria with 12 (4.98%) participants in the ISAV group and 229 (95.02%) participants in the POSA group. The IFI incidence in the POSA group was 14.5%, while the ISAV group did not have any occurrences of IFI. No significant difference was found in the rate of IFI occurrence between the two treatment groups (p  =  0.3805). Furthermore, it was demonstrated that the use of a loading dose when initiating prophylaxis could impact rates of IFI for this patient population.

Conclusion

Due to no difference in incidence, patient specific factors such as concomitant medications and baseline QTc should influence the choice between prophylactic agent.
Hydroxyapatite-Bioceramic/Expanded Perlite Hybrid Composites Coating on Ti6Al4V by Hydrothermal Method and in vitro Behavior
Authors: Muratoğlu Mehtap , Özcan Tuğçe
Published: May 2023

This study was aimed to coat a hybrid bioceramic composite onto Ti6Al4V by using hydrothermal method. The Hybrid bioceramic composite for coating was prepared by reinforcing different rations of expanded perlite (EP) and 5 wt.% chitosan into synthesized Hydroxyapatite (HA). Coating was performed at 1800°C for 12 hours. The coated specimens were gradually subjected to a sintering at 6000°C for 1 hour. For in vitro analysis, the specimens were kept in Ringer’s solution for 1, 10, and 25 days. All specimens were examined by SEM, EDX, FTIR, and surface roughness analyses for characterizing. It was concluded that as the reinforcement ratio increased, there was an increase in coating thickness and surface roughness. The optimum reinforcement ratio for expanded perlite can be 10 wt.% (A3-B3). With increasing ratio of calcium (Ca) and phosphate (P) (Ca/P), the surface becomes more active in body fluid and then observed the formation of the hydroxycarbonate apatite (HCA) layer. As the waiting time increased, there was an increase in the formation of an apatite structure.
Moving from responsibility learning inaction to ‘responsibility learning-in-action’: A student-educator collective writing on the ‘unnoticed’ in the hidden curriculum at business schools
Authors: Chatrakul Na Ayudhya Uracha , Edmondson Michelle , Harris America , Littel Fabien
Published: May 2023

We are a student–educator writing collective that have come together outside the formal classroom to experiment with ‘writing differently’, imbued with a desire to enact collective resistance against ‘unnoticed’ and intentionally hidden aspects of the business school curriculum that condone, normalize and reproduce social injustice and inequalities. As students and educator located in the Department of Organizational Psychology at a UK-based business school, we see our non-traditional writing and inquiry through collective writing as a form of resistance against hegemonic scientific norms of knowledge production that dominate our discipline. We evoked Freire’s problem-posing education through a collective enactment of ‘responsibility learning-in-action’ by participating in regular ‘writing as resistance’ sessions, where we wrote around our lived experiences of the ‘unnoticed’ and intentionally hidden curriculum and responsibility learning in the same virtual space and time and then read aloud to one another. Our coming together through this practice (re)claims relationality and solidarity in the student–educator relationship, which is in itself a contribution to the topic of the intersections between responsibility learning and the hidden curriculum at business schools.
High tide, low price? Flooding alerts and hotel prices in Venice
Authors: Angelini Francesco , Figini Paolo , Leoni Veronica
Published: May 2023

This research explores the effects of High Tide alerts on hotel prices in Venice, a city that is vulnerable to the impacts of extreme climate events due to its fragile ecosystem and a long history of floods in the city center. By analyzing and combining price data from Booking.com with publicly available information on tides and weather, this study uses regression discontinuity design to test for changes in hotel prices when tide levels reach a critical threshold. The results offer insights into the sensitivity of hotel prices to weather alerts and provide valuable information on the potential impact of climate change on Venice’s tourism-driven economy, with implications for the cost–benefit analysis of activating protective barriers for lagoon protection.
Family members’ experiences of seeking help for a young person with symptoms associated with the psychosis spectrum: A narrative review and synthesis
Authors: Rodell Sadie , Parry Sarah
Published: May 2023

Young people often rely on family carers to access support for their mental health. However, stigma can be a barrier to help seeking for young people and families. Little research has been undertaken with young people who experience highly stigmatised symptoms, such as psychosis spectrum symptoms, and even less research has been conducted with parents and carers, meaning barriers to help go unchallenged. Therefore, this narrative review aimed to explore stories of family experiences of seeking help for young people with symptoms associated with the psychosis spectrum. Sources searched were PsycINFO and PubMed. Reference lists of the selected papers were also cross-checked to ensure the search had not missed potential papers for inclusion. Searches returned 139 results, of which 12 were identified for inclusion. A narrative analytic approach was adopted to synthesise qualitative findings to provide a nuanced interpretation of help-seeking experiences. The narrative synthesis provided an opportunity to identify differences, similarities, and patterns across the studies to tell a cumulative emancipatory narrative of family experiences of seeking help for psychosis spectrum symptoms. Help-seeking experiences had a relational impact on families, with stress adding to conflict and anxieties inhibiting hopefulness, although families could emerge stronger and assertively with compassionate support.
‘Where do we come from and where are we going?’ A study about the transformation of knowledge related to long-term care
Authors: Castelo Uzuri , Gil de Montes Lorena , Larrañaga Maider
Published: May 2023

The care crisis manifests the tensions and profound changes which are taking place in contemporary long-term care systems, leading to new care views and modalities in society. Through 26 interviews conducted with caregivers, family members and elderly people with care needs, this study aims to make visible the transformation in the conceptions of care in the Basque Country. First, the results show the displacement of familiarist ideas and values. Second, we describe the daily management of the social and moral tensions associated with outsourcing and the meaning of care work. Third, the findings indicate the emergence of new perspectives on the modalities of care. The contribution of cognitive polyphasia towards analysing the management and integration of new knowledge associated with care in a specific socio-cultural context is discussed. Finally, we consider the applicability of our findings in terms of relevant solutions for care management and innovation in this field.

Published: May 2023

This study investigated the effects of resistance training (RT) on the sleep quality of patients with fibromyalgia (FM), through a systematic review. The search was carried out in the PubMed, Embase, Scopus, and Web of Science databases. Initially, 148 studies were found, of which six were included for qualitative analysis. Four studies showed significant improvement in sleep after RT. Compared to other exercise modalities, RT proved to be superior to flexibility training and equivalent to aerobic exercise. Interventions lasted from 4 to 21 weeks, the weekly frequency ranged from two to three times, and the intensity ranged from 40% to 80% 1RM, with exercises for the major muscle groups. RT is an intervention that can be used to treat FM, however, more studies are needed to verify its effectiveness in improving sleep.
Pre-service language teachers’ perceptions of sustainability and its implementation in language teaching
Authors: Maijala Minna , Heikkola Leena Maria , Kuusalu Salla-Riikka , Laine Päivi , Mutta Maarit , Mäntylä Katja
Published: May 2023

In both the school environment and teacher education, sustainable development is usually linked to the natural and social sciences and is rarely incorporated into language education or encouraged as part of language teacher education. As more research is needed on the practical implementation of sustainable development in language teaching and language teacher education, this study elucidates Finnish pre-service language teachers’ perceptions of sustainability dimensions (i.e. ecological, economic, social, and cultural) and their role in language teaching. We used a questionnaire comprising open-ended and Likert-scale questions to examine pre-service language teachers’ perceptions of and attitudes towards themes under all sustainability dimensions, and their feeling about their ability to integrate them into their teaching. Pre-service teachers ( n = 26) recognized the importance of the social and cultural dimensions in language teaching and felt more capable of addressing personal environmental actions than global problems in the language classroom. Some pre-service teachers produced concrete practices linking sustainability issues with language teaching, but they were mostly teacher-centred. The pre-service teachers did not link equality as tightly to the cultural and social aspects of language teaching as they did in their personal lives. These findings help in developing language teaching and teacher education programmes toward the educational sustainable development goals. Moreover, the questionnaire can be used to analyse the consideration of sustainability themes in language teaching and language teacher education.
Working with children and young people in research: Supportive practices and pathways to impact
Authors: Thomas Ciara , Cockcroft Emma , Jenkins Georgia , Liabo Kristin
Published: May 2023

Children and young people have much to contribute to the design and delivery of health research and care. Nevertheless, there are multiple barriers to meaningful and impactful involvement of children and young people. This narrative review synthesised existing literature on the involvement of children and young people as partners in health research. Authors screened electronic databases and reference lists to identify relevant studies. Data were extracted on how involvement was described, what young people contributed to, and the impact of their involvement. The review identified 15 reports; these reported researcher observations and findings from focus group discussions and questionnaires about the involvement. Impacts recorded in these studies included influence on research; outputs from involvement activities; shifts in researchers’ attitudes; a sense of achievement in young people; and fulfilling relationships. These impacts were associated with principles being followed: building relationships over time to allow for unexpected involvement in the research, flexibility so young people could contribute in ways that work for them, and training. Methods adapted to be youth-appropriate such as visual aids and icebreaker games also enabled impact. Impactful involvement relies on processes that respond to young people’s preferences for engagement and activities that support them to share their views.
Underlying pathways of social inequality in tooth loss: The mediating role of sugary beverages and diabetes
Authors: Hach Maria , Hvidtfeldt Ulla A. , Christensen Lisa B. , Lange Theis , Danielsen Bo , Osler Merete , Diderichsen Finn , Andersen Ingelise
Published: May 2023

Background:

Previous studies show social inequality in tooth loss, but the underlying pathways are not well understood. The aim was to investigate the mediated proportion of sugary beverages (SBs) and diabetes and the association between educational level and tooth loss, and to investigate whether the indirect effect of SBs and diabetes varied between educational groups in relation to tooth loss.

Methods:

Data from 47,109 Danish men and women aged 50 years or older included in the Danish Diet, Cancer and Health Study was combined with data from Danish registers. Using natural effect models, SBs and diabetes were considered as mediators, and tooth loss was defined as having <15 teeth present.

Results:

In total, 10,648 participants had tooth loss. The analyses showed that 3% (95% confidence interval 2–4%) of the social inequality in tooth loss was mediated through SBs and diabetes. The mediated proportion was mainly due to differential exposure to SBs and diabetes among lower educational groups.

Conclusions:

The findings show that SBs and diabetes to a minor degree contribute to tooth-loss inequalities. The explanation indicates that individuals in lower educational groups have higher consumption of SBs and more often suffer from diabetes than higher educational groups.
Low-frequency broadband multidirectional vibration isolation by piezoelectric smart platform with active control
Authors: Zou Wentao , Hu Ningdong , Yang Xue , Hu Hongping
Published: May 2023

A high-precision equipment is very sensitive to vibration, even micro vibration. How to isolate the low-frequency broadband multidirectional vibration remains a challenge. As the main component of piezoelectric smart vibration isolation model, the piezoelectric stack consists of a piezoelectric actuator, a piezoelectric sensor, and a rubber layer. The numerical results obtained by the finite element method agree well with theoretical solutions. The vibration attenuates rapidly under displacement and velocity feedback control with negative gains. As the control gain decreases, the vibration isolation band is extended to lower frequency. A piezoelectric smart multidirectional vibration isolation platform model is further proposed by inclined installation of two piezoelectric stacks. A spring-like structure is designed to exert a preload pressure on these piezoelectric stacks. After optimization on the control gain, the platform can isolate vibration from 0 to 3000 Hz in multiple directions.
Finite element simulation of residual stress of wire arc additive manufactured low alloy high strength steel component assisted by interlayer hammering
Authors: Yang Nan , Dong Hao , Zhu Zhi , Wang Chunxia , Zhao Ling , Guo Xuming
Published: May 2023

Residual stress is an important factor affecting structural deformation, which seriously reduces the dimensional accuracy, fatigue strength, and safety of structural parts. In this study, a coupled thermal-mechanical finite element model for wire arc additive manufacturing (WAAM) was established based on ABAQUS and Fortran subroutine and the accuracy of the simulation results was verified by experiments. The effects of hammering and hammering temperature on the residual stress in low alloy high strength (HSLA) steel built by the WAAM process were analyzed. The results showed that the effect of reducing the residual stress increased and then decreased with the hammer temperature in the hammer temperature range of this study. The optimal hammer temperature was found to be 800 °C. The maximum longitudinal, transverse, and Z-direction residual stress of the deposited wall after 800 °C interlayer hammering decreased by 20.7, 273.9, and 116.9 MPa, respectively.
Dominant Development Indexes’ Construction of Gender and Challenges for Recognizing Everyday Activism for Peace and Security
Authors: Luttrell-Rowland Mikaela , Rhee Sophia , Okujagu Whitney
Published: May 2023

Developed organizations have increasingly garnered numerous indicators to measure gender and development outcomes. Yet, measurements themselves reflect a logic of the arenas where development occurs and can be captured, and therefore reflect where women are imagined to predominantly exist. Based on the analysis of 1,298 indicators across 15 major development databases covering African countries, this article argues that mainstream development organizations predominantly understand gender in terms of institutional sites. Sometimes these were sites for intervention, or a place for institutional ‘betterment’ (a hospital, a work place, and a school). Other times, these sites were conceptualized as natural places where women would be (the family and the nation state). We identify the spatial logics underpinning these development indicators, and link them to larger historical gendered and racialized colonial logics organizing diverse social, economic, and cultural lives, where economic and institutional sites are promoted, a more nuanced and relational one is displaced. Ultimately, these spatial imaginings extend to the larger context of where debates about peace and security are situated—namely in largely individual, state-driven, and institutional-centric ways.
Status of homestay tourism in Indian Himalayan region: Analysis of customer review and policy support for sustainable tourism
Authors: Thakur Smriti , Sood Sagar , Singh Rakesh Kumar , Singh Ranjeet
Published: May 2023

Homestays, which have emerged as a popular idea in the growing tourism industry, act as the most suitable alternative to encourage sustainable tourism activities in the Indian Himalayan Region (IHR). Homestay tourism not only provides economic benefits to rural communities but also promotes local art, architecture, traditions, and food habits. The objective of this study was to determine the distribution of homestays in the IHR and to evaluate and compare homestay management facilities between states; between rural and urban homestays; and based on reviews and ratings from previous guests. The study included all of IHR’s states and union territories. The data for the number of homestays, ratings, and reviews of guests were taken from the popular travel booking sites with the help of a data extracting tool. According to the findings, Himachal Pradesh had the highest number of homestays (968), while Tripura had the least number of homestays (3), compared to all other states and union territories. The homestays in Jammu and Kashmir received the highest ratings. In Himachal Pradesh, homestays were available at a variety of pricing points, ranging from 300 to 38,000 INR a night. Overall, it was observed that rural homestays were equally good as their counterparts in urban areas when the hospitality standards of the rural and urban homestays were compared. To boost the effectiveness of this programme in IHR, the study’s findings may be used to design local policies, rules, and incentive programmes for the areas in which they will be put into practise.
Pandemic-driven consumer behaviour: A foraging exploration
Authors: Wells Victoria , Carrigan Marylyn , Athwal Navdeep
Published: May 2023

COVID-19 has had a profound effect on consumer behaviour. This conceptual piece uses foraging theory, extending and developing the foraging ecology of consumption model, to examine consumer behaviour in a pandemic. It is argued that a foraging interpretation of consumer behaviour is more relevant in situations where supply is uncertain, risks are enhanced and resourcefulness is important. The paper assesses the underlying mechanisms of behaviour change-objectives, currency and constraints – from a foraging perspective and examines their role in changing both patch (retail) choices and which items are consumed (prey choices). Additionally, the paper examines temporal and social challenges within the pandemic. The paper considers whether pandemic consumption behaviours will remain as threat levels subside and concludes with suggestions for future research.
“Arterial stiffness is not associated with changes in the circadian pattern of blood pressure in patients with type 1 diabetes mellitus and cardiovascular autonomic dysfunction”
Authors: Nattero-Chávez Lía , Bayona Cebada Ane , Fernández-Durán Elena , Quintero Tobar Alejandra , Dorado Avendaño Beatriz , Escobar-Morreale Héctor , Luque-Ramírez Manuel
Published: May 2023

Introduction

Cardiovascular autonomic neuropathy (CAN) associates an abnormal circadian pattern in blood pressure (BP) regulation that might be aggravated by the coexistence of arterial stiffness. We aimed to evaluate the effect of arterial stiffness in the circadian rhythm of BP in patients with type 1 diabetes and CAN.

Methods

Cross-sectional study including 56 consecutive patients with type 1 diabetes and CAN, with ( n = 28) or without ( n = 24) arterial stiffness as defined by an ankle-brachial index above 1.2. CAN was diagnosed by BP and heart rate responses to active standing and cardiovascular autonomic reflex tests. Absence of nocturnal decrease in BP–“ non-dipping” pattern– was defined by a daytime to nighttime decrease in mean BP smaller than 10%.

Results

The study’s subjects mean age was 40 ± 11 years-old, their mean duration of diabetes was 22 ± 10 years, and their mean A1c was 7.9 ± 1.5%. A “ non-dipping” pattern was observed in 28 patients (54%) regardless of the presence or absence of arterial stiffness. Age, waist circumference, body mass index, and A1c, were introduced as independent variables into a multiple regression analysis. The stepwise model ( R2: 0.113, p = 0.016) retained only A1c levels (β: ‒ 0.333, 95% confidence interval [CI]: −3.10 to −0.33) as significant predictor of the percentage of nighttime decrease in mean BP.

Conclusions

A non-dipping pattern in BP is very common in patients with type 1 diabetes presenting with subclinical CAN and is associated with a poorer metabolic control. On the contrary, coexistence of arterial stiffness is not associated with abnormalities in circadian BP regulation.
Reactive eco-friendly dyeing of natural fabrics using a novel herbal composite containing extracts of Hemigraphis colorata and Bacopa monnieri
Authors: Karpagavalli VS , Sumithra M
Published: May 2023

Terrestial herbs and aquatic herbs are of natural origin with significant medicinal properties. These properties were selected and aimed to provide antimicrobial and anti-odour activities after finishing with nine different fabric samples in the present study. Hemigraphis colorata and Bacopa monnieri are the two herbs selected and a novel herbal composite (HC1) was developed. Composite was finished onto fabric samples using Pad-dry cure process. Finished fabrics were subjected to antibacterial activity using standard EN ISO 20,645 test method against Escherichia coli and Staphylococcus aureus. To prevent odour from physical activities, aromatic oil was finished onto fabric samples; followed by testing anti-odour activity using Swiss standard SNV 195,651. Test results of antibacterial activity of herbal composite (HC1) finished fabrics revealed good inhibitory action against both test bacteria. Aromatic efficiency of herbal composite finished fabrics showed significant aromatic efficiency. Statistical evaluation determined that there was no significant difference (p–1) between finished and control fabrics in terms of antibacterial activity and aroma. Results for the biocompatibility of the herbal composite finished fabrics revealed that the composite concentrations did not inhibit the growth of fibroblast cells; thus indicating the biocompatibility of the herbal composite finished fabric samples. The present study would be considered highly significant by providing an eco-friendly and sustainable products for developing medical textile products and smart home textile products.

In this article, the author describes their mental health struggles tied to Black Masculinity as a (former) Black athlete. In particular, the author focuses on the stigma surrounding mental health in the Black community and the ways in which Blackness, Black masculinity, and mental health battles emulate the (Black) struggle that must be. The author attempts to highlight the complicated nature of mental health struggles, specifically the ways in which suicide is handled in the world of sport and the ways in which the narrative can have juxtaposed racial frameworks. The author moves into and through their own personal experiences with mental health as a Black man, both in present tense and including personal journal entries, to make sense of “the (Black) struggle that must not be ignored.”
Informed Consent and Debriefing When Deceiving Participants: A Systematic Review of Research Ethics Guidelines
Authors: Verbeke Kamiel , Krawczyk Tomasz , Baeyens Dieter , Piasecki Jan , Borry Pascal
Published: May 2023

Informed consent and debriefing of research participants in studies that use deception are ethical safeguards for which existing scholarly work on their implementation remains variable and insufficiently clear. A systematic review of research ethics guidelines was conducted to sketch a picture of whether, why and how informed consent and debriefing are recommended when using deception. Documents roughly agreed on several general principles, but varied significantly in the specifics of why and whether these safeguards are necessary, in which conditions and how they should be implemented. Various aspects that appear in the literature could not be found in the guidelines. In our review, guidance was integrated and showed a variation of implementation strategies that could help in contextualizing these safeguards.
Comparison of the Early Warning Effects of Novel Inflammatory Markers SIRI, NLR, and LMR in the Inhibition of Carotid Atherosclerosis by Testosterone in Middle-Aged and Elderly Han Chinese Men in the Real World: A Small Sample Clinical Observational Study
Authors: Chen Qinhao , Che Mingzhu , Shen Wei , Shao Lijie , Yu Haiyang , Zhou Jian
Published: May 2023

The purpose of this study was to explore and compare the relationship among serum testosterone, systemic inflammatory response index (SIRI), lymphocyte-to-monocyte ratio (LMR) neutrophil-lymphocyte ratio (NLR), and carotid atherosclerosis in middle-aged and elderly men of Han nationality in the real world. With reference to the inclusion criteria, 89 middle-aged and elderly Han male patients were finally selected. Local weighted regression (LOESS) and multivariate logistic regression models were used to explore the independent correlation between serum testosterone, new inflammatory markers, and atherosclerosis. The diagnostic value of related indexes was evaluated by the receiver working curve characteristic curve (ROC), and the best critical value of testosterone and related inflammatory indexes was discussed. In the LOESS model, bioavailable testosterone (BT), free testosterone (FT), total testosterone (TT) and SIRI, NLR, LMR, and atherosclerosis were significantly correlated. After adjusting for confounding factors, BT, FT, TT, and LMR were negatively correlated with atherosclerosis (odds ratio [OR] < 1, p < .05), and SIRI and NLR were positively associated with atherosclerosis (OR > 1, p < .05). According to the ROC curve results, the area under the curve (AUG) of BT is 0.870, and the optimal threshold point is 4.875. The AUG of SIRI is 0.864, and the best threshold point is 0.769. Low testosterone and high inflammatory levels are closely related to atherosclerosis. Testosterone (TT, FT, and BT) and new inflammatory markers, SIRI, NLR, and LMR, are associated with carotid atherosclerosis in middle-aged and elderly men.

Aiming at the current problems of duplicated paths and low work efficiency in machine punching of warp knitted vamp marker points, this paper proposes a punching path planning method of machine vision combined with intelligent algorithms. The method can improve the timeliness of visual recognition of punching location by limiting the search area and similarity function threshold, and improve the ability of global search and adaptive adjustment in punching path planning by combining with the improved ant colony algorithm to calculate a more accurate and optimized path more efficiently. Through the visual recognition test and the simulation test of the improved ant colony algorithm, the results show that the template matching can correctly identify the positioning hole marker points for different styles, rotation directions and lighting conditions, and the recognition accuracy is 0.43 mm and the repeat positioning accuracy is 0.09 mm; meanwhile, the improved ant colony algorithm can effectively avoid the local optimal solution, which can improve the optimal rate of the result by about 38% and the algorithm can reduce the number of iterations of the optimal solution within 60 times, which greatly saves the calculation time of path planning. The method can be used to improve the efficiency of punching in the actual warp knit vamp punching.

Introduction

This study investigated the relationship between sensory processing, respiratory sinus arrhythmia, and social participation in people with psychiatric disorders.

Method

This study recruited 30 participants, primarily women, from a psychiatric university hospital with a mental health diagnosis listed in the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (mean age: 37.7 ± 16.0 years). Sensory processing, autonomic nervous function, and social participation were measured using the Adolescent/Adult Sensory Profile®, respiratory sinus arrhythmia, and World Health Organization Disability Assessment Schedule, respectively. Through mediation analysis, a model wherein sensory processing mediated the relationship between respiratory sinus arrhythmia and social participation was developed.

Results

Social participation was moderately to highly correlated with Adolescent/Adult Sensory Profile® quadrants (excluding sensory seeking) and respiratory sinus arrhythmia. Furthermore, the mediation analysis revealed that sensory avoiding mediated the relationship between respiratory sinus arrhythmia and social participation, consequently counteracting the direct relationship.

Conclusion

A mediation model was constructed, which indicated that individuals with psychiatric disorders and low parasympathetic nervous system activity expressed higher sensory processing quadrant of sensory avoiding. Ultimately, this was associated with reduced social participation.

Diabetes distress has been shown to be highly prevalent in adults living with type 1 and type 2 diabetes with important implications for glycemic control, self-care, and self-management behaviors. Despite considerable focus on self-management and glycemic targets during pregnancy, current literature lacks information on diabetes distress in pregnancy, particularly in women with type 2 diabetes. This article outlines an explanatory sequential mixed methods research protocol to examine diabetes distress during pregnancy in women with pre-existing diabetes. The aims of the study were to: (1) establish the prevalence and correlates of diabetes distress in women attending a diabetes and pregnancy clinic; (2) use this quantitative data to inform development of an interview guide and plan for sampling for telephone interviews; and (3) explore and describe the experiences of diabetes distress during pregnancy. The quantitative strand was a cross-sectional survey of 76 women using self-reported questionnaires to collect demographic and clinical data, and validated tools to assess health variables, including the outcome of interest of diabetes distress using the Problem Area in Diabetes scale. The qualitative strand applied interpretive description methodology to explore the quantitative results using semi-structured qualitative interviews with 18 women to obtain patient perspectives of diabetes distress and experiences of managing diabetes in pregnancy. The explanatory sequential mixed methods research will provide an opportunity to add contextual qualitative experiences from women with pre-existing diabetes during pregnancy to provide a comprehensive picture of diabetes distress. The results will inform further research priorities that protect and promote mental health, psychosocial well-being, and self-management practices for this population.

The research scope of this paper is to reinforce the need to strengthen university-firm relationship. We consider that it is crucial that the interactions between researcher/university and managers/firms should be based on a win-win relationship. In this sense, it is relevant to determine the main drivers behind the success of collaborative research projects, and this study focuses on one of them: cognitive distance. The specific objective of this study is to analyze the main factors that determine the influence of cognitive distance in the individual relationship between researchers and practitioners in collaborative research projects. In the first stage, through a literature review of cognitive distance and collaborative research projects, we identified a list of seven factors that influence cognitive distance and the issues that may provoke in the empirical context. Second, we carried out an empirical study based on semi-structured interviews with coordinators of collaborative research projects managed by the “Chair of Business Volkswagen Navarra – University of Navarra”. This permitted us to build guidelines that show the main practical concerns associated with each factor and how they were managed in the analyzed projects. This enriches the cognitive distance literature on individual interactions between researchers and practitioners. We highlight the relevance of previous experience of both agents, the exploitation of projects versus exploratory ones, and the determinant role of support infrastructures to minimize the negative effect of high cognitive distance. Nowadays, there is a trend to develop collaborative research projects with firms, not only agreement collaborations. Therefore, our findings could be useful for analyzing the relationships between researchers and practitioners in action research studies developed inside a doctoral thesis or competitive research project. By considering the effect of cognitive distance when selecting collaborative research projects, it will help to increase the degree of success of these projects.
Boundary-spanning practices of system leaders in China: Enabling conditions and inherent tensions
Authors: Qian Haiyan , Walker Allan , Zheng Yulian
Published: May 2023

There is currently considerable interest in system leadership and how it can support school change at scale. System leadership aims to move learning beyond school boundaries through leveraging experience and expertise. The success of system leadership depends on how key educational players can move effectively between and across traditional educational boundaries. China's education system has long-established system infrastructure to support boundary spanning. This paper presents three selected different types of system leaders who span across boundaries to build relationships, interconnections and interdependencies to enhance collective teacher capacity across their systems. The paper argues that working in a centralised, top-down system creates enabling conditions which facilitate boundary practices. It further suggests that such conditions form tensions which risk reproducing static systems when leadership is enacted hierarchically. Enabling conditions include established routines, roles and values which empower boundary spanners to leverage their expertise. System tensions can arise between the centre and periphery, between responsibility and professional power and between diversity and homogeneity.
