Machismo and Caballerismo Linked with Perceived Social Discrimination and Powerlessness in U.S. Latino Men
Authors: Hendy Helen M. , Can S. Hakan , Heep Hartmut
Published: December 2021

Concepts from the Threat Appraisal and Coping Theory, Precarious Manhood Theory, and Ambivalent Sexism suggest that U.S. Latino men who perceive social discrimination and powerlessness may respond with machismo beliefs that serve as coping responses to empower themselves and reassert their manhood. Machismo beliefs include both aggressive “traditional machismo” and gentlemanly family-focused “caballerismo.” Because past research has revealed that individuals respond to social abuse with anger, prompting them to feel empowered but less empathetic, we hypothesized that Latino men who perceive social discrimination combined with a sense of powerlessness would report more traditional machismo and less caballerismo. We also hypothesized that this three-variable sequence would be stronger for men with high rather than low in Latino identity, since discrimination would be a more personal threat to their identity and manhood. Participants included 1,530 U.S. Latinos who completed online surveys to report demographics (age, education, employment, sexual orientation, partner status, household size), perceived social discrimination, powerlessness, traditional machismo, caballerismo, and Latino identity. Mediational analyses confirmed the three-variable sequence in which powerlessness mediated associations between social discrimination and (more) aggressive machismo, and (less) gentlemanly caballerismo. Also as hypothesized, moderated mediational analysis revealed that these three-variable sequences were stronger for men with high rather than low Latino identity. With recent increases in social discrimination against U.S. Latinos, present results caution that men may respond to these challenges with increased aggressive patterns of traditional machismo.
Spotlight Personnel: How Hiring and Turnover Drive Service Performance Versus Demand
Authors: Eckert Christine , van Heerde Harald J. , Wetzel Hauke A. , Hattula Stefan
Published: December 2021

In many sectors of the entertainment industry, a few employees attract the public spotlight when performing the core service. For example, in professional team sports, a team of players competes in games, and in TV shows, a cast of artists acts in different episodes. These employees, coined “spotlight personnel,” are an essential but expensive element of ongoing service delivery. Despite their importance and cost, very little is known about how changes in spotlight personnel affect service performance and demand. To address this gap, this article uses unique data on professional German soccer teams, tracking the quantity (number of players) and quality (average transfer price) of spotlight personnel hiring (incoming transfers) and turnover (outgoing transfers), objective service performance (winning percentage), and demand (ticket sales) across four decades, using both traditional and novel time series methods. The results show that service performance and demand are primarily affected by spotlight personnel hiring rather than by turnover. Hiring quantity decreases service performance yet increases demand, whereas hiring quality benefits both service performance and demand. The analysis further uncovers that these effects are subject to dynamic interactions and nonlinearities. Investment scenarios showcase how understanding these effects can substantially improve managerial decision making.
Perspectives of Students With Disabilities and Their Parents on Influences and Barriers to Joining and Staying in Extracurricular STEM Activities
Authors: Fisher Karin M. , Shannon-Baker Peggy , Greer Kania , Serianni Barbara
Published: December 2021

Students with disabilities (SWDs) are less likely to establish themselves successfully in science, technology, engineering, and mathematics (STEM) careers. Researchers have identified barriers to participation in STEM, including deficits in mathematics and science, executive functioning skills, and self-efficacy, and lack of exposure to STEM experiences. Researchers found students who participate in STEM clubs have higher grades in STEM content areas, have better attitudes toward school, and are more likely to graduate. This study aimed to understand student and parent perceptions about the influences and challenges to participation in STEM clubs. We used a sequential explanatory mixed-methods design that began with a survey, followed by focus groups and interviews with parents and SWDs. We identified four salient meta-themes regarding what influences students to join and stay in a STEM club: fun and the subject matter, social and peer interactions, parent and teacher initiative, and a “semblance of normal.” In addition, we identified meta-themes on the barriers for SWDs to join and stay in STEM clubs. These include being a good fit, having no student interest, others not making accommodations, and overwhelmed parents. This article concludes with recommendations for educators to make STEM clubs more inclusive.
Participatory Theater as Fieldwork in Chinese Prisons: A Research Note
Authors: Xiaoye Zhang
Published: December 2021

This methodological reflection is based on the author's own experience taking part in participatory theater projects in mainland Chinese prisons over the past 5 years. This article demonstrates how the author's participation in prison theater projects secured otherwise unattainable research access by forming collaborations with various organizations. Participatory theater workshops also offered the space for sustaining long-term rapport. This research note discusses why trusting relationships are the most important guarantee to obtaining valid data in Chinese prison research. The findings contribute to understanding methodological challenges and innovations of conducting fieldwork in criminal justice systems with no formal research access channels.
Managing Opioid Agonist Therapy in the Post-Soviet Limbo
Authors: Dmitrieva Alexandra , Stepanov Vladimir , Mazhnaya Alyona
Published: December 2021

According to Dante, “Limbo” is the first circle of Hell located at its edge. Unlike other residents of Hell, the Limbo population suffers no torment other than their lack of hope. We argue that a lack of hope in post-Soviet Ukraine is expressed by a lack of conditions for a better future since the past is overrepresented in the present. Therefore, every movement transforms under the past’s pressure, changing its course in order to reproduce and perpetuate ghosts of what is long gone. We argue that the current state of Ukraine can be framed as “post-Soviet limbo.” If the great stability of the Soviet regime was a result of overregulation and extensive control, or of “uncertainty avoidance,” then a post-Soviet limbo is a result of “managing uncertainty” simultaneously influenced by Soviet legacies and neoliberal promises of growth, calculability, and deregulation on the part of the State. “Soviet legacies” are dominant and represent a mix of formal overregulation explicitly presented through laws and policies and informality which, according to some authors, became even more widespread in the post-Soviet period than it used to be under the Soviet rule. We do not aim to consider the past legacies as being opposite to neoliberal features and futures, but negotiate the way the two are interrelated and mutually reinforced in the present to produce the post-Soviet limbo. Ukraine’s performance of Opioid Agonist Therapy (OAT) coverage is consistently estimated as insufficient and needing further improvement. However, we argue that that there are two modes of OAT implementation in Ukraine: state-funded (formal) and privately-funded (informal). The latter’s size does not fall into official estimates since the national reports on OAT performance never include the numbers of patients involved in informal treatment. We suggest, that the informal mode of OAT implementation appeared as a result of contrasting efforts towards intensive regulation and extensive growth. To understand how these two modes are produced in the context of post-Soviet narcology, how they differ and where their paths cross, we analyze two types of texts: legal and policy documents regulating substance use disorder (SUD) treatment, mainly OAT; and qualitative data, including interviews with OAT patients and field notes reflecting the environment of OAT programs. Finally, the presented article seeks to answer how the state’s contrasting efforts to manage the uncertainty of SUD treatment through OAT regulation and implementation reproduce the post-Soviet limbo and, thus, people with SUD as “patients of the state” who are frozen in a hopeless wait for changes.
Computational fluid dynamics optimization of gas drainage technology in gas-mining areas
Authors: Zhao Wei , Qin Wei
Published: December 2021

Coal mining results in strata movement and surrounding rock failure. Eventually, manual mining space will be occupied by the destructed coal rock, making it difficult to conduct field tests of the coal seam to explore gas seepage and transport patterns. Therefore, computational fluid dynamics (CFD) numerical computation is an important tool for such studies. From the aspect of gas pre-drainage, for layer-through boreholes in the floor roadway of the 8,406 working face in Yangquan Mine 5 in China, reasonable layout parameters were obtained by CFD optimization. For effectively controlling the scope of boreholes along coal seam 9 in the Kaiyuan Mine, CFD computation was performed. The results revealed that the horizontal spacing between boreholes should be ≤2 m when a tri-quincuncial borehole layout is used. Optimization of the surface well position layout for the fault structure zone in the Xinjing Mine of the Yangquan mining area indicated that the horizontal distance between the surface well and the fault plane should be <150 m. From the aspect of gas drainage with mining-induced pressure relief, CFD computation was performed for pressure-relieved gas transport in the K8205 working face of Yangquan Mine 3. The results showed that forced roof caving should be used before the overhang length of hard roof reaches 25 m in the K8205 working face to avoid gas overrun. From the aspect of gas drainage from the abandoned gob, surface well control scopes at different surface well positions were computed, and an O-ring fissure zone is proposed as a reasonable scope for the surface well layout. CFD computation has been widely applied to coal and gas co-extraction in the Yangquan mining area and has played a significant role in guiding related gas drainage engineering practice.
Embracing Paradox: TMT paradoxical processes as a steppingstone between TMT reflexivity and organizational ambidexterity
Authors: van Neerijnen Pepijn , Tempelaar Michiel P. , van de Vrande Vareska
Published: December 2021

Top management teams are crucial in managing the ambidexterity paradox. This endeavour, however, generates cognitive conflicts. Surprisingly, this particular topic has received little attention within the ambidexterity literature. We aim to address this lacuna and, in doing so, extend the paradox literature and the emerging socio-cognitive perspective on ambidexterity. In our hypothesized mediation model, top management teams embrace the exploration-exploitation paradox through reflexivity, then overcome this paradox through paradoxical cognitive processing – the capacity to cognitively differentiate and integrate exploration and exploitation – which finally fosters ambidexterity. We test and find support for our hypotheses using a sample of 335 Dutch and German small and medium enterprises. We end with a discussion on how socio-cognitive factors influence the management of the ambidexterity paradox. In doing so, we refine scholarly understanding of motivating and enabling factors that allow top management teams to deal with the paradoxical tensions surrounding ambidexterity.
Pneumatocele formation following COVID-19 pneumonia. Is there a role for surgical intervention?
Authors: McCann Cameron , Shoeib Mohamed , Rashid Muhammad Iftikhar , Kostoulas Nikos
Published: December 2021

COVID-19 mainly causes a lower respiratory tract illness, meaning there has been great interest in the chest and lung radiological findings seen during the course of the disease. Most of this interest has centred around the computed tomographic findings. Most commonly, computed tomographic images report ground-glass opacities but a less common finding, and potential complication associated with COVID-19, is pneumatocele formation. In this case series, we describe the presentation and management of three patients with large pneumatoceles that developed during the recovery phase of COVID-19. A conservative approach is most recommended, with surgical intervention reserved for complicated cases that cause cardiorespiratory compromise.
Feasibility and Effectiveness of Telecounseling on the Psychological Problems of Frontline Healthcare Workers Amidst COVID-19: A Randomized Controlled Trial from Central India
Authors: Gupta Snehil , Kumar Mohit , Rozatkar Abhijit R. , Basera Devendra , Purwar Shashank , Gautam Disha , Jahan Rahat
Published: December 2021

Background:

Preliminary reports suggest that during the COVID-19 pandemic, telecounseling could be an effective model of psychological intervention for the frontline healthcare workers (fHCW) with psychological problems. Literature is sparse in this area, particularly from low- and middle-income countries, including India. We aimed to investigate the feasibility and the effectiveness of telecounseling (vs. general education) on the psychological problems of the fHCW over three time-points (baseline vs. end-of-session and at two and four weeks after the intervention).

Methods:

The study followed a single-blind, active arm versus general education, parallel-group randomized control design, with participant allocation in 1:1. Active healthcare workers (HCWs) with mild- to-severe or clinically concerning scores on any of the sub-scales of Depression, Anxiety and Stress Scale (DASS-21) or Impact of Event Scale-Revised (IES-R; represented by higher scores) were included, while those with known psychiatric illness were excluded. Chi-square and Mann-Whitney U test and linear-mixed effect model (group-, time, and group by time-effect) were used for analysis.

Results:

There were no baseline group differences (telecounseling group, active arm, n = 9; general education group, control arm, n = 10). A significant time-effect (P = 0.044 to <.001) was found on DASS-21 on intention-to-treat analysis. Per-protocol analysis, additionally, found a significant group effect on Impact of Event Scale-Revised (IES-R; P = 0.036). A significant random effect of the participants was also found (P <.001).

Conclusion:

Telecounseling could be a feasible and scalable model of psychological interventions for the fHCW with psychological problems, albeit with some feasibility challenges.
Regulating domestic and care work in Italy: Assessing the relative influence of the familistic model today
Authors: De Vita Luisa , Corasaniti Antonio
Published: December 2021

The domestic and care sector continues to display some problematic aspects due to its complexity, especially in terms of regulation. Italy represents a unique and peculiar case, where domestic and care work remains firmly under the purview of family management, and the work itself is entrusted mainly to immigrant workers. This paper aims to investigate, through in-depth interviews with representatives of both unions and employers’ associations, how the key actors involved in regulating domestic and care work intervene, understanding what kind of measures they take and what systems of relations/exchange exist among the different players involved in this process. The research sought to map strategies at a more macro level. While some of the actions undertaken by the social partners seem promising, there is still a lack of full responsibility for care at the public level, with marked asymmetries with respect to both services provided and working conditions.
Habitual caffeine consumption moderates the antidepressant effect of dorsomedial intermittent theta-burst transcranial magnetic stimulation
Authors: Frick Andreas , Persson Jonas , Bodén Robert
Published: December 2021

Background:

Potentiating current antidepressant treatment is much needed. Based on animal studies, caffeine may augment the effects of currently available antidepressants.

Objective:

Here, we tested whether habitual caffeine consumption moderates the antidepressant effects of repetitive transcranial magnetic stimulation (rTMS) using intermittent theta-burst stimulation (iTBS).

Methods:

Forty patients with current depressive episodes were randomized to active iTBS ( n = 19) or sham treatment ( n = 21; shielded side of the coil and weak transcutaneous electrical stimulation) delivered two times per day for 10–15 weekdays. Neuronavigated stimulation was applied to the dorsomedial prefrontal cortex. Symptom improvement was measured using change in self-reported Montgomery-Åsberg Depression Rating Scale (MADRS) scores. Pretreatment habitual caffeine consumption was quantified using self-reports of number of cups of coffee and energy drinks consumed the 2 days before the treatment starts.

Results:

Habitual caffeine consumption was associated with symptom improvement following active iTBS ( r = 0.51, 95% confidence interval (CI): 0.08–0.78, p = 0.025) but not following sham treatment ( r = −0.02, 95% CI: −0.45 to 0.42, p = 0.938). A multiple regression analysis corroborated the findings by showing a significant caffeine consumption × treatment group interaction (β = 0.62, p = 0.043), but no main effects of treatment group (β = 0.22, p = 0.140) or caffeine consumption (β = −0.01, p = 0.948). No group differences in pretreatment symptom scores or caffeine consumption were detected ( p values > 0.86).

Conclusion:

Habitual caffeine consumption moderated the antidepressant effect of dorsomedial iTBS, consistent with caffeine improving antidepressant pharmacological treatments in animals. Caffeine is an antagonist of adenosine receptors and may enhance antidepressant effects through downstream dopaminergic targets.
‘The Everyday Work of Repair’: Exploring the Resilience of Victims-/Survivors of Conflict-Related Sexual Violence
Authors: Natalya Clark Janine
Published: December 2021

This interdisciplinary article uses what Das has termed ‘the everyday work of repair’ as a framework for thinking about resilience. It is not the first to discuss resilience and the everyday. What is novel is the context in which it does so. Extant scholarship on conflict-related sexual violence has largely overlooked the concept of resilience. Addressing this gap, the article draws on semi-structured interviews with victims-/survivors of conflict-related sexual violence in Bosnia and Herzegovina (BiH), Colombia and Uganda to examine what everyday resilience ‘looks’ like and how it is expressed within and across highly diverse social ecologies. In so doing, it reflects on what everyday resilience means for transitional justice, through a particular focus on hybridity. It introduces the term ‘facilitative hybridity’, to underscore the need for transitional justice processes to give greater attention to the social ecologies that can crucially support and enable the everyday work of repair and everyday resilience.

Authors: Alhaj Omar A. , Al-Sayyed Hiba F. , Charouf Ola M. , Jahrami Haitham , Morris Keith
Published: December 2021

Purpose:

This study aimed to translate and test the content validity and reliability of an English questionnaire used in the American food and health survey.

Methods:

The questionnaire was developed using 6 stages, then examined for test–retest. A total of 672 participants were recruited for validation and reliability. Validity test was performed using a correlation coefficient to measure the linear correlation between 2 questions at one given time. Moreover, the Kaiser-Meyer-Olkin, Measure of Sampling Adequacy, and Bartlett’s Test of Sphericity were performed to statistically determine the suitability for conducting exploratory factor analysis. Furthermore, reliability tests using Cronbach α was used to estimate the reliability coefficient properties of the translated scale. Finally, the most important correlated questions was plotted using a color-coded correlogram.

Results:

The test–retest reliability of all tested items was significantly correlated. The reliability test for all questions was 0.9. The cross-correlation test showed that all questions of the translated questionnaire were correlated significantly ( P < .05) indicating reliability of the questionnaire.

Conclusion:

The tested questionnaire is applicable and may be used in population-based studies to raise awareness regarding health, food consumption, nutrition, and food safety among people in Jordan and/or other Arab countries.
Youth Perspectives on Integrated Youth Services: A Discrete Choice Conjoint Experiment
Authors: Henderson Joanna , Hawke Lisa D. , Iyer Srividya N. , Hayes Em , Darnay Karleigh , Mathias Steve , Thabane Lehana
Published: December 2021

Objective

Integrated youth services (IYS) are an emerging model of care offering a broad range of mental health and social services for youth in one location. This study aimed to determine the IYS service characteristics most important to youth, as well as to determine whether different classes of youth have different service preferences, and if so, what defines these classes.

Methods

Ontario youth aged 14–29 years with mental health challenges were recruited to participate in a discrete choice experiment (DCE) survey. The DCE contained 12 attributes, each represented by 4 levels representing core characteristics of IYS models. To supplement the DCE questions, demographic information was collected and a mental health screener was administered. Preferences were examined, latent class analyses were conducted, and latent classes were compared.

Results

As a whole, participants endorsed the IYS model of service delivery. Among 274 youth, there were three latent classes: 1) the Focused Service (37.6%) latent class prioritized efficient delivery of mental health services. 2) The Holistic Services (30.3%) latent class prioritized a diverse array of mental health and social services delivered in a timely fashion. 3) The Responsive Services (32.1%) latent class prioritized services that matched the individual needs of the youth being served. Differences between classes were observed based on sociodemographic and clinical variables.

Conclusions

IYS is an acceptable model of care, in that it prioritizes components that reflect youth preferences. The differences in preference profiles of different groups of youth point to the need for flexible models of service delivery. Service design initiatives should take these preferences into account, designing services that meet the needs and preferences of a broad range of youth. Working locally to co-design services with the youth in the target population who wish to be engaged will help meet the needs of youth.

Authors: Polo-Blanco Irene , González López María J. , Bruno Alicia , González-Sánchez Jon
Published: December 2021

This study, which used a multiple baseline across participants’ design, examines the effectiveness of a modified schema-based instructional approach to improve the mathematical word problem solving performance of three students with mild intellectual disability, two of whom had an autism spectrum disorder. Following the intervention, the three students improved their performance when solving addition and subtraction change word problems; however, their performance was inconsistent on change word problems. The effects of the instruction were generalized to two-step addition and subtraction word problems for the three participants. Moreover, the results were generalized to an untrained setting and were maintained 8 weeks after the instruction. The implications of these findings for teaching problem-solving skills to students with intellectual disability are discussed.
A new fault diagnosis model of rolling element bearing based on a recurrent neural network
Authors: Song Xudong , Zhu Dajie , Sun Shaocong
Published: December 2021

The rolling element bearing is an important part of mechanical equipment, it has various kinds of malfunctions, the location of the fault may occur in the inner ring, outer ring, or rolling element of the bearing. Therefore, traditional methods of classification are difficult to classify and identify effectively. To improve the accuracy of bearing fault diagnosis, the deep learning method is used to diagnose the fault of the rolling element bearing. In this paper, the long short-term memory and gated recurrent unit are combined to build a bearing fault diagnosis model. On the other hand, this paper adjusts the hidden layer structure and optimizes the network parameters to establish a better long short-term memory–gated recurrent unit–long short-term memory diagnostic model and classify the fault types of bearings with Softmax. The model proposed in this paper can effectively diagnose the bearing fault under the bearing data set of Case Western Reserve University and the University of Cincinnati. Compared with the traditional long short-term memory and the gated recurrent unit, the model proposed in this paper has high accuracy in fault diagnosis as well as certain reliability and generalization ability.
Experimental analysis of dropwise condensation heat transfer on a finned tube: Impact of pitch size
Authors: Aminian Ehsan , Saffari Hamid
Published: December 2021

Condensation is one of the essential processes in diverse industries due to its widespread use in various industrial applications such as power generation, water desalination, and air conditioning. Much research has been conducted to achieve better efficiencies and better heat transfer performances in condensers in the past decades. Condensation is divided into dropwise and filmwise based on the surface free energy, surface roughnesses, and condensate characteristics. This study investigated the influence of the 1-Octadecanethiol coating on vertically grooved copper tube’s condensation heat transfer characteristics. The hydrophobic surfaces have been created using self-assembled monolayers (SAMs) on the pure copper tubes (99.9% Cu). Moreover, four different pitch sizes of 1.5, 2, 2.5, and 3.5 mm have been implemented on the surface. Finally, the heat flux and the heat transfer coefficient as functions of logarithmic mean temperature difference are reported in the result section. For validation, the results obtained from the experiment were compared with available data in the literature, and an acceptable agreement was achieved. According to the results, it was found that the 1.5-mm pitch size has the highest heat flux, and the 3.5-mm pitch size has the lowest heat flux. Additionally, it can be inferred that the maximum heat flux of 696.71 kW/m2 was attributed to the 1.5-mm pitch size for logarithmic mean temperature differences of 64.3 K, which is approximately 1.24 times higher compared to the plain tube.

Authors: Erazo-Martínez Valeria , Nieto-Aristizábal Ivana , Ojeda Isabella , González Michelle , Aragon Cristian C , Zambrano María Andrea , Tobón Gabriel J , Arango Johanna , Echeverri Alex , Aguirre-Valencia David
Published: December 2021

Objective

Pregnant women with SLE have higher probabilities of maternal complications. SLE during pregnancy has alternating patterns of remission and flare-ups; however, most pregnant SLE patients tend to worsen with associated poor obstetric and perinatal outcomes. This study aimed to describe obstetric outcomes in pregnant women with SLE.

Methods

This retrospective study was performed between 2011 and 2020 at a highly complex referral health center in Cali, Colombia. Pregnant women with a diagnosis of SLE were included. Demographic, clinical, and laboratory features and obstetric and fetal outcomes, including intensive care unit (ICU) characteristics, were evaluated.

Results

Forty-eight pregnant women with SLE were included. The median age was 29 (25–33.7) years. The SLE diagnosis was made before pregnancy in 38 (79.1%) patients, with a median disease duration of 46 (12–84) months. Thirteen (27.1%) patients had lupus nephritis. Preterm labor (34, 70.8%), preeclampsia (25, 52%), and preterm rupture of membranes (10, 20.8%) were the most common obstetric complications. A relationship between a greater systemic lupus erythematosus pregnancy disease activity index (SLEPDAI) and the development of hypertensive disorders during pregnancy was established (preeclampsia = p < 0.0366; eclampsia = p < 0.0153). A relationship was identified between lupus nephritis (LN) and eclampsia ( p < 0.01), preterm labor ( p < 0.045), and placental abruption ( p < 0.01). Seventeen (35.4%) patients required ICU admission; 52.9% of them were due to AID activity, 17.6% for cardiovascular damage, 11.7% for septic shock, and 5.8% for acute kidney failure. Fetal survival was 89.5% ( N = 43/48). Among the live births, two (4.2%) newborns were diagnosed with neonatal lupus, and two (4.2%) were diagnosed with congenital heart block. One maternal death was registered due to preeclampsia and intraventricular hemorrhage.

Conclusions

This study is the first to describe SLE during pregnancy in Colombia. SLE was the most prevalent AID in this cohort, and complications included preterm labor, preeclampsia, and postpartum hemorrhage. A higher SLEPDAI and lupus nephritis predicted adverse maternal outcomes.
Caregiver decision-making concerning involuntary treatment in dementia care at home
Authors: Moermans Vincent RA , Mengelers Angela MHJ , Bleijlevens Michel HC , Verbeek Hilde , de Casterle Bernadette Dierckx , Milisen Koen , Capezuti Elizabeth , Hamers Jan PH
Published: December 2021

Background:

Dementia care at home often involves decisions in which the caregiver must weigh safety concerns with respect for autonomy. These dilemmas can lead to situations where caregivers provide care against the will of persons living with dementia, referred to as involuntary treatment. To prevent this, insight is needed into how family caregivers of persons living with dementia deal with care situations that can lead to involuntary treatment.

Objective:

To identify and describe family caregivers’ experiences regarding care decisions for situations that can lead to involuntary treatment use in persons living with dementia at home.

Research design:

A qualitative descriptive interview design. Data were analysed using the Qualitative Analysis Guide of Leuven.

Participants and research context:

A total of 10 family caregivers providing care for 13 persons living with dementia participated in in-depth semi-structured interviews. Participants were recruited by registered nurses via purposive sampling.

Ethical consideration:

The study protocol was approved by the Ethics Committee of the University Hospitals Leuven and the Medical Ethical Test Committee Zuyderland.

Findings:

Family caregivers experience the decision-making process concerning care dilemmas that can lead to involuntary treatment as complicated, stressful and exhausting. Although they consider safety and autonomy as important values, they struggle with finding the right balance between them. Due to the progressive and unpredictable nature of dementia, they are constantly seeking solutions while they adapt to new situations. Family caregivers feel responsible and experience social pressure for the safety of persons living with dementia. They may be blamed if something adverse happens to the persons living with dementia, which increases an already stressful situation. Their experience is influenced by characteristics of the care triad (persons living with dementia, professional and family caregivers) such as practical and emotional support, knowledge, and previous experiences.

Discussion and conclusion:

To prevent involuntary treatment, professionals need to proactively inform family caregivers, and they need to support each other in dealing with complex care situations.

Authors: Murakami Nozomu , Tanabe Kouichi , Morita Tatsuya , Fujikawa Yasunaga , Koseki Shiro , Kajiura Shinya , Nakajima Kazunori , Hayashi Ryuji
Published: December 2021

Background: The purpose of this study was to clarify how the Regional Referral Clinical Pathway for Home-based Palliative Care (RRCP-HPC) and an outreach program by a palliative care team (PCT) lead to an improvement in the outcome. Design and Methods: We conducted questionnaire surveys using the mailing method involving the regional medical staff involved in cancer patients introduced to the PCT of a single hospital, as well as bereaved families. The questionnaire was prepared through interviews with the medical staff and bereaved families. Subsequently, factor analysis was performed to identify factor structures and calculate the correlation coefficient with each outcome. Results: For the questionnaire survey involving the medical staff, responses were collected from 119 regional medical institutions and 84 regional medical staff. The response rate per institution was 51.3%. Similarly, for the questionnaire survey involving bereaved families, the response rate was 42.4%. For the survey involving the medical staff, 6 factors, such as “improved awareness of an interdisciplinary team,” were extracted. For the survey involving the bereaved families, 4 factors, such as “improvement of communications between patients and healthcare professionals,” were extracted. There were significant (≥moderate) correlations between these factors and all outcomes. Conclusion: In this study, we clarified the process of achieving palliative care until death at home without difficulties using the outreach program and RRCP-HPC. The results suggest the importance of improving communications. The outreach program and RRCP-HPC may have contributed to palliative care at home without difficulties through an improvement in communications.
Protective Factors Against Psychological Distress Among Inpatients in Substance Use Treatment: A Cross-Sectional Study
Authors: Bøhle Kari , Otterholt Eli , Bjørkly Stål
Published: December 2021

Several studies have found co-occurrence between substance abuse and mental health problems, as well as an association between treatment retention and psychological distress. The aim of this study was to investigate the association of possible protective factors with psychological distress. The present study tested physical activity, self-esteem and sense of coherence, and psychological distress level among inpatients in substance use treatment. The study design was cross-sectional and multicenter. Patients (N = 167) were recruited in 2018 from 10 Norwegian inpatient facilities. They self-reported on 3 validated measurement instruments: Rosenberg Self-Esteem Scale, Antonovsky’s Sense of Coherence Scale, and frequency of physical activity. The Hopkins Symptom Checklist-10 was used as an outcome variable of psychological distress. The associations were investigated with multiple linear and logistic regression methods. The results suggested that high self-esteem and sense of coherence were protective factors against high levels of psychological distress: self-esteem (β = −.39, P < .001) and sense of coherence (β = −.352, P < .001). The results offer support for a salutogenic approach in substance use disorder (SUD) treatment by enhancing individuals’ protective factors to reduce psychological distress.
Buprenorphine Dosage and Urine Quantitative Buprenorphine, Norbuprenorphine, and Creatinine Levels in an Office-Based Opioid Treatment Program
Authors: Furo Hiroko , Schwartz Diane G , Sullivan Ross W , Elkin Peter L
Published: December 2021

Background:

Treatment progress is routinely monitored by urine testing in patients with opioid use disorder (OUD) undergoing buprenorphine medication-assisted treatment (MAT). However, interpretation of urine test results could be challenging. This retrospective study aims to examine the results of quantitative buprenorphine, norbuprenorphine, and creatinine levels in urine testing in relation to sublingual buprenorphine dosage to facilitate an accurate interpretation of urine testing results.

Methods:

We reviewed the medical charts of 41 consecutive patients, who were residing in halfway houses where their medication intake was closely monitored and who had enrolled in an office-based MAT program at an urban clinic between July 2018 and June 2019. The patients’ urine testing results were reviewed, and demographic variables were recorded. We focused on the patients treated with 8-, 12-, or 16-mg/day of buprenorphine, examining their urine buprenorphine, norbuprenorphine, and creatinine levels. Analysis of variance tested the statistical association between the dosage and urine testing results on the norbuprenorphine-to-creatinine ratio.

Results:

A total of 240 urine samples from 41 patients were included for this study. The 41 patients received a mean buprenorphine dose of 10.5 ± 3.7 mg/day (range, 4-20 mg/day). Then, this study examined the distribution of the 240 urine samples and then focused on 184 urine samples that came from the 33 patients who were treated with 8-, 12-, and 16-mg/day of buprenorphine, the 3 most common dosages. All of the 184 urine samples had a creatinine level of >20 mg/dL and buprenorphine-to-norbuprenorphine ratio <50:1. The average norbuprenorphine-to-creatinine ratio in the 8 mg/day dosage group was 3.85 ± 2.24 × 10−4 (n = 66; range, 0.44-11.12). The respective ratios in the 12- and 16-mg dosage groups were 5.64 ± 3.40 × 10−4 (n = 83; range, 1.55-22.72) and 6.23 ± 4.92 × 10−4 (n = 35; range, 1.37-27.12). The 3 dosage groups differed significantly in the mean ratios ( P < .01), except when the 12- and 16-mg dosage groups were compared ( P = .58). The results of this study thus suggest that prescribers should pay attention to the following features: (1) unexpected substance(s) in urine testing, (2) creatinine level under 20 mg/dL, (3) buprenorphine-to-creatinine ratio over 50:1, (4) buprenorphine dosage over 24 mg/day, and (5) norbuprenorphine-to-creatinine ratio consistently under 0.5 × 10−4 in patients treated with 8 mg/day or 1.5 × 10−4 in patients treated with 12 mg/day or more.

Conclusion:

This study suggested parameters for interpreting quantitative urine test results in relation to buprenorphine intake dose in office-based opioid treatment programs.

Published: December 2021

Nowadays, grease lubrication is frequently used in rolling element applications such as bearings or constant velocity joints. The advantage of grease is to supply lubrication to the application without leaking thanks to its consistency. Nevertheless, starvation can occur leading to damage such as scuffing.

In the present study, starvation is analyzed using the Starvation Degree parameter through tests with different operating conditions and different types of greases.

Published: December 2021

The performance of the rolling bearing of a spindle device is directly related to the safety and reliability of the operation of a mine hoist. To extract bearing vibration signal features effectively for fault diagnosis, a feature extraction method based on the parameter optimization of a variational mode decomposition (VMD) method and permutation entropy (PE) is proposed. In addition, a support vector machine (SVM) classifier is used to identify bearing fault types. An analogue signal is used to test the effect of noise and sampling frequency on VMD performance. Focused on the problem of the VMD method needing to determine the number of mode components K and a penalty factor α during the signal decomposition process, a genetic algorithm is used to optimize the parameter combination [K,α] with the minimum sample entropy as the indicator. By using mean squared error (MSE) and correlation coefficient, an evaluation indicator is constructed to determine the decomposition effects of the optimized VMD, centre frequency, empirical mode decomposition (EMD) and ensemble EMD (EEMD) methods. The normalized PE of the five mode components is used as an eigenvalue, which is used as the input parameter of the SVM. Two different experimental datasets are used to verify the effectiveness of the proposed method. The results show that the proposed method has better diagnostic accuracy than EMD, EEMD and a BP neural network in the case of limited samples and unknown sample inputs. It can provide a good reference for the diagnosis of a rolling bearing and has practical application value.

Published: December 2021

Background:

Atopic dermatitis (AD) is a common chronic-relapsing inflammatory skin disease hallmarked by epidermal barrier dysfunction, increased transepidermal water loss (TEWL) and decreased skin hydration. Recent findings on the T helper 2 (Th2)-driven pathogenesis of AD have led to the development of dupilumab, a monoclonal antibody directed against interleukin-4 and interleukin-13 that has been demonstrated to be effective in the treatment of moderate-to-severe AD. The effect of dupilumab on skin barrier dysfunction, however, has not yet been adequately investigated.

Objectives:

The primary endpoint of this study was to assess the status of the skin barrier in nonlesional skin of patients with severe AD treated with dupilumab, by evaluating the association between the relative variation of TEWL and the achievement of a 75% reduction of EASI (EASI75) over time.

Methods:

TEWL was measured below the antecubital fossae by means of the Vapometer® at baseline, at week 4 (T4), at week 16 (T16) and at week 32 after dupilumab starting. EASI and NRS-itch were measured at the same time points.

Results:

Seventy-eight patients with severe AD treated with dupilumab were enrolled. Median TEWL relative variation respect to baseline was significantly higher in patients who achieved EASI75 as compared with those who did not achieve EASI75 at T16 and at T32, but not at T4.

Conclusion:

During dupilumab treatment, TEWL on nonlesional skin tends to significantly improve 4 months after treatment initiation and could be a good tool for monitoring response to therapy.
Does issue framing shape support for COVID-19 lockdown measures? Evidence from a survey experiment in Peru
Authors: Carreras Miguel , Vera Sofia , Visconti Giancarlo
Published: December 2021

Two issue frames quickly emerged in policy and media communications about COVID-19 lockdown measures. Initially, a public health frame advocated for strong quarantine policies to slow the spread of the virus. As the economic costs associated with quarantine measures became clear, an economic frame pushed for an end to (or a relaxation of) these measures to alleviate the economic damage associated with lockdowns. We do not know much about how these competing communication frames affected lockdown support, especially in poor- and middle-income countries. To explore this question, we embedded a framing experiment in a nationally representative telephone survey in May 2020 in Peru, one of the world’s hardest-hit countries by the coronavirus pandemic. The vignette experiment reveals that the economic frame produces a decrease in public support for quarantine measures in Peru. In contrast, respondents exposed to a health frame do not increase their approval of the same measures.
Use of an aiming drill guide and ankle arthroscopy for reduction of depressed articular surface in posterior malleolar fractures
Authors: Lee Hyo-Jin , Kim Sung Jae , Park Young Uk , Hyun Jintak , Kim Hyong Nyun
Published: December 2021

Purpose

We describe a novel technique that uses an aiming drill guide and ankle arthroscopy for direct visualization and reduction of the depressed articular surface located between the posterior tibia and the fractured posterior malleolus. This technique requires less soft tissue dissection to visualize and reduce the depressed articular surface.

Methods

Between June 2014 and May 2019, 126 patients were surgically treated for trimalleolar fractures. Among them, 11 had depressed articular fragment between the posterior tibia and the fractured posterior malleolus reduced using our novel technique. The study included six men and five women, with a mean age of 46.5 (range: 23–62) years.

Results

In eight (73%) cases, the articular surface was reduced, with the articular surface step-off being less than 2 mm, as noted on postoperative computed tomography (CT). Syndesmosis congruity within an anterior-to-posterior difference of less than 2 mm was confirmed in nine (82%) cases via postoperative CT. The mean 100-mm visual analog scale (VAS) and the mean Olerud-Molander ankle score at the final follow-up were 16.6 ± 14.5 and 87.7 ± 7.5, respectively.

Conclusions

The depressed articular fragment located between the posterior tibia and the fractured posterior malleolus can be treated using an aiming drill guide and ankle arthroscopy. Ankle arthroscopy is used for direct visualization of the depressed articular surface, and the aiming drill guide can guide the bone plunger precisely to the depressed articular surface for reduction. This technique requires less soft tissue dissection than conventional techniques to visualize and reduce the depressed articular surface.

Published: December 2021

Background: Distal chevron osteotomy (DCO) is commonly performed in hallux valgus surgery. The fixation of the osteotomy is provided by various implants. The usage of biodegradable implants such as magnesium is gradually increasing due to the advantages they provide. In this study, we aimed to compare the fixation of DCO with magnesium or titanium screw biomechanically. Methods: Twenty sawbones were used. The samples were divided into two equal groups, including ten sawbones for fixation with single headless titanium (group-1) or magnesium screw (group-2). DCO and screw fixations were performed on all samples using the same technique. Biomechanical testing was applied to five samples in each group in cantilever and the other five in a physiological configuration using a computer connected to the electromechanical test machine. The obtained data were evaluated using the Shapiro–Wilk test, Student’s t-test and Mann–Whitney U test on the IBM® SPSS (Statistical Package for the Social Sciences) V22.0 software. Significance was accepted at the p < 0.05 level. Results: There was no statistically significant difference between the magnesium screw and the titanium screw in terms of maximum force, maximum displacement and stiffness measurements in cantilever and physiological loadings ( p > 0.05 for all). Conclusion: This study found no significant difference in biomechanical stability between the magnesium and titanium screws in DCO fixation on sawbones. Further studies with real bones are needed.
