Food consumption, habitus and the embodiment of social change: Making class and doing gender in urban Vietnam
Authors: Ehlert Judith
Published: May 2021

This article draws on Bourdieu’s concept of habitus as a means to analyse social distinction and change in terms of class and gender through the lens of food consumption. By focusing on urban Vietnam, this qualitative study looks into the daily practices of food consumption, dieting and working on the body as specific means to enact ideal body types. Economically booming Vietnam has attracted growing investment capital in the fields of body and beauty industries and food retail. After decades of food insecurity, urban consumers find themselves manoeuvring in between growing food and lifestyle options, a nutrition transition, and contradicting demands on the consumer to both indulge and restrain themselves. Taking this dynamic urban context as its point of departure and adopting an intersectional perspective, this article assesses how eating, dieting and body performance are applied in terms of making class and doing gender. It shows that the growing urban landscape of food and body-centric industries facilitates new possibilities for distinction, dependent not only on economic capital but on bodily and cultural capital also, and furthermore, how social habitus regarding food–body relationships are gendered and interlaced with class privilege.
Policy Discourses: Shifting the Burden of Healthcare from the State to the Market in the Kingdom of Saudi Arabia
Authors: Rahman Redwanur , Salam Mohammad Asif
Published: May 2021

Saudi Arabia has modified from a predominantly free, public, and comprehensive system under a welfare model to more of a mixed-economy model of healthcare. The welfare state slowly moved to a liberal model, emphasizing market forces to dominate in the provision of healthcare and the private sector was trusted to provide a better provision of healthcare. The country has to confront enormous problems in the health sector due to population growth, lifestyle changes, the shift of disease patterns, elevated expectations, escalated healthcare costs, limited infrastructure and resources, and poor management practice in the provision of healthcare. Moreover, the government has been emphasizing the need to bring in private sector investment to improve quality and efficiency, development of manpower, and standardization of services. As the current pattern of healthcare is unsustainable, the country is planning to restructure the present healthcare system toward institutionalizing it to meet future challenges. The governments must make an appropriate amount of effort to build their healthcare systems by transforming and modifying the challenges faced by society and its political-economic systems. The government should encourage equity, and fairness in the provision of healthcare.

Published: May 2021

In carrying out surveys involving sensitive characteristics, randomized response models have been considered among the best techniques since they provide the maximum privacy protection to the respondents and procure honest responses. Over the years, researchers have carried out studies on the estimation of proportions of the population possessing sensitive characteristics. However, there is a paucity of research studies that have addressed higher order interactions between these sensitive characters. In this article, we develop a new theory based on three proposed randomized response models which we name as: simple model, semi-crossed model, and fully crossed model. Twenty-one new unbiased estimators of seven parameters are introduced, their variance expressions are derived, and unbiased estimators of variances are developed. The three models are compared under various values of the parameters by computing the percent relative efficiency of one model over another model. The most efficient model is then applied to study the population proportions of three varieties of smoking habits among students, and their first- and second-order interactions. The last four sections (Ninth to Twelfth) are verifications of theoretical results using the Cramer–Rao lower bounds of variances for the developed 21 new estimators in randomized response sampling.

Published: May 2021

As swelling occurs, CSF is preferentially displaced from the ischemic hemisphere. The ratio of CSF volume in the stroke-affected hemisphere to that in the contralateral hemisphere may quantify the progression of cerebral edema. We automatically segmented CSF from 1,875 routine CTs performed within 96 hours of stroke onset in 924 participants of a stroke cohort study. In 737 subjects with follow-up imaging beyond 24-hours, edema severity was classified as affecting less than one-third of the hemisphere (CED-1), large hemispheric infarction (LHI, over one-third the hemisphere), without midline shift (CED-2) or with midline shift (CED-3). Malignant edema was LHI resulting in deterioration, requiring osmotic therapy, surgery, or resulting in death. Hemispheric CSF ratio was lower on baseline CT in those with LHI (0.91 vs. 0.97, p < 0.0001) and decreased more rapidly in those with LHI who developed midline shift (0.01 per hour for CED-3 vs. 0.004/hour CED-2). The ratio at 24-hours was lower in those with midline shift (0.41, IQR 0.30–0.57 vs. 0.66, 0.56–0.81 for CED-2). A ratio below 0.50 provided 90% sensitivity, 82% specificity for predicting malignant edema among those with LHI (AUC 0.91, 0.85–0.96). This suggests that the hemispheric CSF ratio may provide an accessible early biomarker of edema severity.
Family Obligation, Parenting, and Adolescent Outcomes Among Mexican American Families
Authors: Yan Jinjin , Hou Yang , Shen Yishan , Kim Su Yeong
Published: May 2021

The current study investigates how and under what conditions family obligation benefits Mexican American adolescents’ adjustment. The study used two waves of data from 604 Mexican American adolescents (54.3% female, Mage.wave1 = 12.41 years, SD = 0.97) and their parents. Structural equation modeling revealed that both adolescents’ and parents’ sense of family obligation related to more supportive parenting (i.e., parental monitoring, warmth, and inductive reasoning), which linked to better adolescent adjustment (i.e., sense of life meaning, resilience, and grades). There were parent gender differences: Adolescents’ family obligation was more strongly related to their reports of maternal (vs. paternal) parenting. The links also varied across informants for parenting: (a) individuals’ sense of family obligation related only to their own perceptions of parenting and (b) there were more evident associations between adolescent-reported (vs. parent-reported) parenting and adolescent outcomes.
How Faculty Status Impacts Student Evaluations of Teaching: A Study of Full- Versus Part-Time Marketing Faculty
Authors: Tashchian Armen , Kalamas Hedden Maria , Forrester William R.
Published: May 2021

The present multiyear study sheds light on the effects of faculty status on student evaluations of teaching (SETs). By comparing actual SETs of full- versus part-time marketing faculty, this study fills a void in the marketing education literature. Collecting first-hand institutionally administered SETs ( N = 6,123) over a seven-year period, the extended data collection phase includes 21 semesters and 240 undergraduate courses. Study findings reveal that students perceive full-time faculty as more knowledgeable, enthusiastic, and better prepared for class than part-time faculty. Full-timers are also better able to communicate the subject matter and develop assignments focused on student learning than part-timers. In contrast, students perceive part-time faculty as better able to relate the course material to the real world, develop exam questions that reflect lectures and assignments, and return graded material more quickly than full-time faculty. Compared with part-time faculty, students perceive full-time faculty as being more rigorous and tougher in terms of grading. Given the differences regarding instructor knowledge, pedagogical skill, rigor, and grading, the discussion of the findings rests on how faculty status affects the overall quality of higher education.

Published: May 2021

Objective

To examine the echocardiographic changes and quality of life (QoL) after surgical unroofing of myocardial bridges (MBs) involving the left anterior descending (LAD) coronary artery compared with optimal medical therapy (OMT).

Methods

Twenty-two patients (median age, 24 years; interquartile range, 16–40 years) with MBs of the LAD artery and exertional angina from 2018 to 2019 were retrospectively analyzed. Twelve patients underwent OMT and 10 underwent surgery. Both groups underwent clinical and echocardiographic examinations during hospitalization and follow-up (mean, 1.0 ± 0.8 years). QoL was assessed with the Seattle Angina Questionnaire, short version (SAQ-7).

Results

Surgery resulted in significantly better QoL than OMT, with a significant improvement in left ventricular global longitudinal strain (GLS) [mean (standard error): 19% (0.19) to 22% (0.34) and 19% (0.15) to 20% (0.24), respectively; delta-change (delta-GLS) of 0.15 vs. 0.067]. In the univariate and multivariable analyses, delta-GLS was positively correlated with the SAQ-7 score and MB length (rho = 0.64 and 0.71, respectively), with a significant interaction between MB length and surgical treatment (beta coefficient, 1.95; 95% confidence interval, 0.14–3.77).

Conclusions

MB unroofing surgery provided benefits in terms of QoL and left ventricular GLS improvement compared with 1 year of OMT.
Impact of Non-Aeronautical Revenues on Airport Landing Charge in Global Airports
Authors: Shin Taejin , Roh Taewoo
Published: May 2021

The airport industry, which is heavily regulated, has shown interest in improving performance by increasing non-aeronautical revenues (NAR) to cope with changes in the aviation environment, including trends toward liberalization and privatization. This study uses panel data from three separate years (2012, 2014, and 2016) to analyze how a high NAR share might affect airport charging policies and explores the impact of NAR on landing charges of global airports grouped by type of aircraft. The data was collected from 137 airports worldwide, and generalized least squares regression was performed by including data obtained from the ATRS (Air Transport Research Society) Global Airport Benchmarking Reports. The results indicate that an increase in the NAR share has a statistically significant negative effect on airport charges. This study provides meaningful implications from an empirical analysis of how a change in an airport’s business model, such as increasing the NAR share, might affect airport charges. This study’s results are expected to encourage international airports to be more active in promoting commercial activities (e.g., duty-free shops) and pursue a pricing policy that can bring them a competitive advantage.
The Anterolateral Ligament Has Limited Intrinsic Healing Potential: A Serial, 3-Dimensional–Magnetic Resonance Imaging Study of Anterior Cruciate Ligament–Injured Knees From the SANTI Study Group
Authors: Saithna Adnan , Helito Camilo Partezani , Vieira Thais Dutra , Sonnery-Cottet Bertrand , Muramatsu Koichi
Published: May 2021

Background:

Recent imaging studies demonstrate that the anterolateral ligament (ALL) is frequently injured at the time of anterior cruciate ligament (ACL) rupture. The intrinsic healing potential of these injuries after ACL reconstruction (ACLR) has not been defined.

Purpose/Hypothesis:

The primary objective was to evaluate the rate and duration of the healing process of injured ALLs after ACLR using serial 3-dimensional magnetic resonance imaging (3D-MRI). The secondary objective was to investigate whether any patient, injury, or surgical factors influenced the healing rate. The hypothesis was that serial imaging would demonstrate that the ALL has limited healing potential.

Study Design:

Case series; Level of evidence, 4.

Methods:

Patients enrolled in the study underwent 3D-MRI (slice thickness 0.5 mm) preoperatively and at 1, 6, 12, and 24 months after ACLR. Three observers determined the grade of ALL injury according to the Muramatsu classification. Inter- and intraobserver reliabilities were calculated. The rates of injury and time points for healing were determined. Full healing was defined as a change from a preoperative Muramatsu grade of B or C (indicating partial or complete injury) to grade A (normal). Multivariate analysis was used to investigate the association of aforementioned factors with the risk of incomplete healing.

Results:

A total of 44 patients were enrolled in the study. Of them, 71.2% had an ALL injury on preoperative imaging. Overall, full healing of ALL injuries occurred at a rate of 3.2%, 15.2%, and 30.3% at 1, 6, and 12 months, respectively. There were no changes in the Muramatsu grade in any patient beyond 12 months postoperatively. None of the complete lesions demonstrated full healing, but the proportion of patients with a grade C injury decreased from 13.6% preoperatively to 4.5% at 12 months due to an improvement to grade B in 4 of 6 patients (66%). Inter- and intraobserver reliabilities of the classification system were almost perfect at 0.81-0.94 and 0.95-1.00, respectively. None of the potential risk factors investigated were predictive of an increased risk of nonhealing.

Conclusion:

ALL injuries occurred in the majority of ACL-injured knees. They had limited intrinsic healing potential, with only 30.3% healing by 12 months after ACLR. The process of healing took >6 months in half of the patients in whom it occurred. No new cases of full healing occurred beyond 12 months postoperatively. No significant risk factors for failure of full healing to occur were identified, but it is likely that this aspect of the study was underpowered.
Prevalence and Covariates of Food Insecurity Across the First 1000 Days Among Women of Mixed HIV Status in Western Kenya: A Longitudinal Perspective
Authors: Alvarez Gloria G. , Miller Joshua D. , Santoso Marianne V. , Wekesa Pauline , Owuor Patrick Mbullo , Onono Maricianah , Young Sera L.
Published: May 2021

Background:

Food insecurity (FI) is common globally and can have lifelong consequences. However, few studies have longitudinally examined how FI varies across gestation and the postpartum period (“the first 1000 days”); none have explored this in sub-Saharan Africa or in the context of HIV.

Objective:

To assess the prevalence and covariates of FI in the first 1000 days among Kenyan women.

Methods:

All pregnant women attending 7 clinics in western Kenya (n = 1247) were screened for HIV and FI (Individual Food Insecurity Access Scale) between September 2014 and June 2015. A subset of women (n = 371) was recruited into an observational cohort study and surveyed 11 times through 2 years postpartum (NCT02974972, NCT02979418). Data on FI, sociodemographics, and health were repeatedly collected. Severe FI was modeled using multilevel, mixed-effects logistic regressions (n = 346).

Results:

Of the 1247 pregnant women screened, 76.5% were severely food insecure in the prior month. Further, the prevalence of severe FI was higher among women living with HIV than those without (82.6% vs 74.6%, P < .05). In the cohort, the odds of being severely food insecure decreased monotonically after delivery. Each point higher on the Center for Epidemiologic Studies-Depression scale was associated with 1.08 times greater odds of being severely food insecure (95% CI: 1.05-1.10); each point higher on the Duke/UNC Functional Social Support Scale was associated with 0.97 lower odds of severe FI (95% CI: 0.94-0.99).

Conclusions:

Severe FI is prevalent during the first 1000 days in western Kenya. Services to mitigate the far-reaching consequences of this modifiable risk should be considered.
Endovascular management of vascular renal injuries: outcomes and comparison between traumatic and iatrogenic settings
Authors: Salvatori Fabio , Macchini Marco , Rosati Marzia , Boscarato Pietro , Alborino Salvatore , Paci Enrico , Candelari Roberto
Published: May 2021

Purpose:

To evaluate the efficacy of endovascular treatment for vascular renal injuries (VRIs) like bleeding, pseudoaneurysm and artero-venous fistula (AVF) and to compare patients with blunt trauma (T-VRIs) with those with iatrogenic damage (I-VRIs).

Methods:

We retrospectively assessed 49 renal artery embolizations performed to treat T-VRIs (26.5%) and I-VRIs (73.5%). Different embolic materials were used based on the type of lesion. Technical success was defined as the complete occlusion of target arteries with no further visualization of VRIs. Clinical success was defined if no recurrence was present and if renal function (difference between creatinine after and before treatment <0.5 mg/dl) was preserved after 1 month.

Results:

Angiography showed bleeding in 27 patients, pseudoaneurysm in 29 and an AVF in 6. Embolic agents used were coils in 39 procedures, coils with sponge in four and others in six. Technical success was 100% while clinical success was 85.7% due to seven patients with recurrence. The group I-VRIs showed a higher rate of clinical success than the group T-VRIs (94.4% vs 61.5%; p < 0.05). Moreover, the group I-VRIs had a higher incidence of pseudoaneurysms and AVFs compared with the group T-VRIs (69.4% vs 30.8% and 16.7% vs 0%; p < 0.05).

Conclusion:

Endovascular treatment for VRIs showed satisfactory results and no patient had a worsening of renal function. I-VRIs had better clinical success and more frequently appeared as pseudoaneurysms compared to T-VRIs: probably iatrogenic injury is localized and pseudoaneurysm is easily identifiable and treatable with endovascular treatment.
What Do Peers Think About Sexting? Adolescents’ Views of the Norms Guiding Sexting Behavior
Authors: Burén Jonas , Holmqvist Gattario Kristina , Lunde Carolina
Published: May 2021

This study examined the content of injunctive peer norms (i.e., perceived peer approval) of sexting among Swedish adolescents. Written answers from 808 adolescents ( Mage = 14.22) to an open-ended question about peers’ views of sexting were analyzed qualitatively using content analysis. Eight categories were distinguished for when and why sexting is acceptable or not in the peer group. A substantial share of adolescents believed their peers approve of sexting, especially if sexting occurs within trusted relationships and when all parties have consented. A large share of adolescents described that peers were non-accepting of sexting, emphasizing that it can be spread to others. The participants also suggested that sexting is seen as a gendered phenomenon surrounded by sexual double standards, with girls at more risk of negative consequences. Some participants emphasized the peer view that adolescents sext to seek attention, and some emphasized that sexting is viewed as an enjoyable activity. Several of these categories’ likelihood to be mentioned was related to the adolescents’ age, gender, and prior experience of sexting. We concluded that adolescents might have a hard time navigating the social context of sexting, given the conflicting and gendered messages from peers.
Pulmonary Barotrauma in COVID-19 Patients With ARDS on Invasive and Non-Invasive Positive Pressure Ventilation
Authors: Rajdev Kartikeya , Spanel Alan J. , McMillan Sean , Lahan Shubham , Boer Brian , Birge Justin , Thi Meilinh
Published: May 2021

Background:

We experienced a high incidence of pulmonary barotrauma among patients with coronavirus disease-2019 (COVID-19) associated acute respiratory distress syndrome (ARDS) at our institution. In current study, we sought to evaluate the incidence, clinical outcomes, and characteristics of barotrauma among COVID-19 patients receiving invasive and non-invasive positive pressure ventilation.

Methodology:

This retrospective cohort study included adult patients diagnosed with COVID-19 pneumonia and requiring oxygen support or positive airway pressure for ARDS who presented to our tertiary-care center from March through November, 2020.

Results:

A total of 353 patients met our inclusion criteria, of which 232 patients who required heated high-flow nasal cannula, continuous or bilevel positive airway pressure were assigned to non-invasive group. The remaining 121 patients required invasive mechanical ventilation and were assigned to invasive group. Of the total 353 patients, 32 patients (65.6% males) with a mean age of 63 ± 11 years developed barotrauma in the form of subcutaneous emphysema, pneumothorax, or pneumomediastinum. The incidence of barotrauma was 4.74% (11/232) and 17.35% (21/121) in the non-invasive group and invasive group, respectively. The median length of hospital stay was 22 (15.7 −33.0) days with an overall mortality of 62.5% (n = 20).

Conclusions:

Patients with COVID-19 ARDS have a high incidence of barotrauma. Pulmonary barotrauma should be considered in patients with COVID-19 pneumonia who exhibit worsening of their respiratory disease as it is likely associated with a high mortality risk. Utilizing lung-protective ventilation strategies may reduce the risk of barotrauma.
Factors Contributing to Violent Discipline in the Classroom: Findings From a Representative Sample of Primary School Teachers in Tanzania
Authors: Masath Faustine Bwire , Hinze Laura , Nkuba Mabula , Hecker Tobias
Published: May 2021

The need for intervention strategies aiming to reduce teachers’ use of violent discipline methods has been expressed repeatedly, especially for countries where this practice is socially and legally accepted. Nevertheless, initial targets for interventions are not clearly identified, as factors contributing to teachers’ use of violence are still understudied. In the present study, we examined the interplay between teachers’ own experiences of violence, their attitudes, current stress, and their use of violent discipline in a representative sample of 173 Tanzanian primary school teachers (53.7% female, Mage = 38.1 years, SDage = 10) using structural equation modeling. Our model showed good model fit ( χ2 [48, n = 173] = 78.058 ( p = .004), CFI = .962, TLI = .948, RMSEA = .060 [90% CI [.034, .084], PCLOSE = .233], SRMR = .048). Results indicated direct associations between positive attitudes toward violent discipline ( β = .41), stress ( β = .23), and teachers’ own experiences of violence ( β = .21) with teachers’ use of violence. Teachers’ own experiences of violence were significantly associated with positive attitudes ( β = .39), and these significantly mediated the association between teachers’ own experiences of violence and their use of violent discipline ( β =.23). Our findings underscore the relevance of past experiences, societal norms, and current working conditions in understanding teachers’ violence against students. Interventions aiming to reduce teachers’ use of violent discipline may focus on stress management, societal norms, personal beliefs on violent discipline, and how teachers’ own previous experiences of violence may influence teacher’s disciplining behavior.
Cultural Beliefs, Perceptions, and Experiences on Female Genital Mutilation Among Women and Men: A Qualitative Analysis
Authors: González-Timoneda Alba , Sánchez Antonio Cano , González-Timoneda Marta , Ros Vicente Ruiz
Published: May 2021

The practice of female genital mutilation (FGM) is a deeply-rooted tradition that affects predominantly regions of Africa and Asia. Because of migration flows, FGM is an issue of increasing concern worldwide. FGM is now carried out in Europe, North America, Australia and New Zealand, and more specifically among immigrant communities from countries where it is common. This study aims to assess the experience, knowledge, attitudes, and beliefs related to FGM of migrant women and men from FGM-affected countries residing in Spain and the United Kingdom. A phenomenological qualitative approach was used. Participants (n=23) were recruited by using the snowball sampling technique until data saturation was reached. Data were collected through 18 open-ended interviews and a focus group. Of the 23 participants, 20 women had undergone FGM. The following five themes were generated from interviews: (a) FGM practice development, (b) knowledge about the practice, (c) reasons for performing FGM, (d) attitudes toward continuing or abandoning the practice, and (e) criminalization of FGM. The study here presented identifies a lack of information, memory, and knowledge about the practice of FGM and typology among women with FGM. The justification of the practice seems to be based on a multifactorial model, where sociocultural and economic factors, sexual factors, hygienic-esthetic factors, and religious-spiritual factors take on a greater role in the analysis of the interviews carried out. The participants practically unanimously agree to advocate the abandonment and eradication of this harmful traditional practice. The knowledge displayed in this study may provide a basis for improving awareness and healthcare in such collectives, aiming the eradication of this harmful traditional practice.
A teacher like me? Different approaches to examining personality similarity between teachers and students

Published: May 2021

Research suggests that people tend to like others more if they are similar rather than dissimilar to themselves. Likewise, students may tend to prefer teachers with whom they share similar personality characteristics. To test this hypothesis, we examined the role of personality similarity between students and teachers in predicting how much students liked their teachers. Secondary school students ( N = 634) provided self-reports and reported on their teachers’ personality using a Big Five personality scale. Their teachers ( N = 31) also provided self-reports. These reports were then used to compute three indices of similarity; i.e. perceptual similarity, actual similarity, and perceptual accuracy which were used to explain teacher liking. Multilevel linear models showed that perceptual similarity (computed as the profile agreement across student self- and teacher-ascribed Big Five traits) had the largest effect on teacher liking. Teachers described as more agreeable and conscientious were liked by their students more. Findings highlight the importance of considering students’ perceptions of personality similarity with their teachers for understanding how students feel “connected” to their teachers and positively interact with them.
Why Is Human Milk Donation Absent From the Literature on Philanthropic Giving? The Invisible Female Donor and Her Invisible Gift
Authors: Oreg Ayelet , Appe Susan
Published: May 2021

In this research note, we call attention to human milk donation being essentially omitted from the philanthropy literature and bodily gifting research. We focus here on human milk donations for infant feeding through nonprofit milk banks. We argue that its omission is due to two main factors: (a) the incoherence of defining human milk donation and the challenges to its regulation and (b) its consideration as care work and the characteristics of the milk donor identity. We end with avenues for future research in this area.
From cohort to community: The emotional work of birthday cards in the Medical Research Council National Survey of Health and Development, 1946–2018
Authors: Elizabeth Hannah J. , Payling Daisy
Published: May 2021

The Medical Research Council National Survey of Health and Development (NSHD) is Britain’s longest-running birth cohort study. From their birth in 1946 until the present day, its research participants, or study members, have filled out questionnaires and completed cognitive or physical examinations every few years. Among other outcomes, the findings of these studies have framed how we understand health inequalities. Throughout the decades and multiple follow-up studies, each year the study members have received a birthday card from the survey staff. Although the birthday cards were originally produced in 1962 as a method to record changes of address at a time when the adolescent study members were potentially leaving school and home, they have become more than that with time. The cards mark, and have helped create, an ongoing evolving relationship between the NSHD and the surveyed study members, eventually coming to represent a relationship between the study members themselves. This article uses the birthday cards alongside archival material from the NSHD and oral history interviews with survey staff to trace the history of the growing awareness of importance of emotion within British social science research communities over the course of the 20th and early 21st centuries. It documents changing attitudes to science’s dependence on research participants, their well-being, and the collaborative nature of scientific research. The article deploys an intertextual approach to reading these texts alongside an attention to emotional communities drawing on the work of Barbara Rosenwein.
Does the position of a sustentacular screw influence the stability of a plate osteosynthesis of a calcaneal fracture? A biomechanical study
Authors: Pazour Jan , Horák Zdeněk , Džupa Valér
Published: May 2021

The purpose of the study was to compare the stability of the plate osteosyntheses of intra-articular calcaneal fractures using various types of a sustentacular screw insertions. A geometrical model of a calcaneal fracture was created. The fracture was fixed with a plate and screws with a uniform distribution. The individual models differed regarding the position of the sustentacular screw. The screw was inserted using three different variants: Model A: into the tip of sustentaculum tali, Model B: under the sustentaculum tali, and Model C: into the inferior peripherial rim of the sustentacular fragment. In all three variants, the screw was either locked into the plate via threads or unlocked. The model was loaded with force in the vertical direction. The stiffness of individual models was evaluated using the finite element method, which was expressed as the maximum force (Fmax) that the system was able to transmit and by determining the magnitude and distribution of reduced stress (σred) on the individual parts of the model of a fixed calcaneal fracture. The greatest stiffness of the system was observed in the Model B (Fmax = 335.8 N). The least stiffness was observed in Model C (Fmax = 296.3 N). This model also produced the greatest load on bone tissue was observed (σmaxred = 67.5 MPa). The least load on bone tissue was measured in Model B (σmaxred = 53.7 MPa). The load on the plate was similar in all three models (814.0–820.0 MPa). The analyses suggest that in a plate osteosynthesis of a calcaneal fracture, the insertion of a sustentacular screw under the tip of the sustentaculum tali is acceptable in terms of osteosynthesis stability. This sustentacular screw position reduces the risk of the screw penetrating into the talocalcaneal joint.
Risk of adverse pregnancy outcomes in Japanese systemic lupus erythematosus patients with prior severe organ manifestations: A single-center retrospective analysis
Authors: Nakai Takehiro , Kitada Ayako , Fukui Sho , Okada Masato
Published: May 2021

Background

Systemic lupus erythematosus (SLE) increases the incidence of adverse pregnancy outcomes (APOs). Nevertheless, most of the data on SLE pregnancies were derived from database studies in which details of the pregnancies were unavailable, and no consensus exists on the risk of APO in patients with prior severe organ manifestations.

Methods

SLE patients followed by rheumatologists and gynecologists throughout pregnancy at our institute were retrospectively identified, and their data between April 2003 and December 2020 were reviewed from electronic records. We assigned patients based on the presence of prior severe organ manifestation (renal/neurological manifestation, prior treatment with methylprednisolone pulse therapy/prednisolone 1 mg/kg/day/biological or cytotoxic therapy) and compared the incidence of overall and serious APO (maternal death, pregnancy loss, preterm birth <32 weeks, birthweight <1500 g, Apgar score <7 at 5 min and birth defect).

Results

This study included 34 pregnancies in 32 patients; 23 pregnancies in 22 patients were classified as SLE with prior severe organ manifestation. There was no statistical difference in the incidence of overall APO between the two groups (52.2% vs 45.5%, P = 1). Among patients with prior severe organ manifestation, 17.4% had serious APO. A detailed electronic health record search revealed specific causes of APO in all pregnancies with serious APO, except the presence of prior severe organ manifestation.

Conclusion

The incidence of overall APO in SLE patients was not affected by prior severe organ manifestation. Although the incidence of serious APOs increased in patients with previous severe organ manifestation, there were other risk factors for poor pregnancy outcomes besides prior lupus severity. Therefore, proper management by rheumatologists and gynecologists may enable patients with prior severe organ manifestation to safely deliver healthy babies.
Expression pattern of tissue-resident memory T cells in cutaneous lupus erythematosus
Authors: Gu Hyeon-Jung , Song Shinyoung , Roh Joo Young , Jung YunJae , Kim Hee Joo
Published: May 2021

Background

Tissue resident memory T cells (TRMs) persist long-term in peripheral tissues without recirculation, triggering an immediate protective inflammatory state upon the re-recognition of the antigen. Despite evidence incriminating the dysregulation of TRMs in autoimmune diseases, few studies have examined their expression in cutaneous lupus erythematosus (CLE).

Objectives

We aimed to examine whether there are differences among TRM populations in CLE depending on different clinical conditions, such as the CLE subtype or association with systemic lupus erythematosus, and to determine the effect of type I interferon (IFN) on the development of TRMs in CLE.

Methods

CLE disease activity was evaluated using the Cutaneous Lupus Erythematosus Disease Area and Severity Index. The expression of the TRM markers CD69 and CD103 in CLE lesions was evaluated by immunofluorescence. Flow cytometry was performed on peripheral blood mononuclear cells after IFNα treatment.

Results

The number of TRMs expressing either CD69 or CD103 was significantly higher in CLE lesions than in control skin; however, it was not significantly different between discoid lupus erythematosus and subacute CLE, or dependent on the presence of concomitant systemic lupus. Lesional severity was not correlated with an increase in TRMs in CLE. IFNα treatment induced a conspicuous increase in CD69 expression in skin-homing T cells, more profoundly in CD4+ T cells than in CD8+ T cells.

Conclusions

Skin TRMs, either CD69 or CD103-positive cells, showed increased levels in the lesional skin of CLE, and IFNα increased the expression of CD69 in T cells.

This review aimed to investigate national estimates of sugar-sweetened beverage (SSB) consumption in children and adolescents aged two to 18 years, from countries in regions particularly burdened by dietary-related chronic illnesses. The most recent studies or reports from included countries (n = 73) with national-level consumption data of SSBs in children and adolescents, collected between January 2010 and October 2019, were considered for inclusion. A random effects meta-analysis was used to calculate pooled estimates of the mean consumption of SSB in millimeters per day. Heterogeneity between national estimates was assessed using the I2 statistic and explored via subgroup analyses by the World Health Organization region, age groups, and country-level income. Forty-eight studies were included in the review reporting national estimates of consumption for 51 countries. The highest estimate of daily consumption was in China at 710.0 mL (95% confidence interval (CI) [698.8, 721.2], while the lowest was in Australia at 115.1 mL (95% CI [111.2, 119.1]). Pooled synthesis of daily SSB consumption of the 51 countries was 326.0 mL (95% CI [288.3, 363.8]), although heterogeneity was high, and was not explained by subgroup analyses. While there is considerable variability between countries, intake of SSB remains high among children and adolescents internationally underscoring the need for public health efforts to reduce SSBs consumption.
Exploring the Association Between Short-cycle School Improvement Planning and Student Achievement in Underperforming Schools
Authors: VanGronigen Bryan A. , Meyers Coby V.
Published: May 2021

Some governments require that educational leaders working in underperforming schools create school improvement plans (SIPs) to guide change efforts. Extant research describes two common approaches to SIPs: (a) a “traditional” approach where leaders create a single plan for an entire academic year, and (b) a “short-cycle” approach where leaders create two plans during an academic year (e.g., one for each semester). Despite widespread appeal, surprisingly little research has been conducted on SIPs and their influence on outcomes of interest. Nearly all studies investigate the traditional approach, and no published studies examine the potential influence of short-cycle SIPs on outcomes of interest (e.g., student achievement). In response to these gaps, the purpose of this study was to explore potential associations between short-cycle SIP quality and student achievement in English/language arts (ELA) and mathematics. We used a publicly available rubric to score 389 short-cycle SIPs on 12 planning domains and then employed a correlational design to examine potential relationships between short-cycle SIP quality and student achievement. Results concluded that short-cycle SIP quality increased over time, but despite small, positive relationships between increased short-cycle SIP quality and increased student achievement, there were no statistically significant impacts. Given the number of factors found to influence student learning, these results are unsurprising, but nevertheless encouraging. We close by discussing how educational leaders might need training to best leverage the short-cycle approach and how future research efforts can continue contributing to a sparse, but growing knowledge base on school improvement planning approaches.
Legislative Diversity and the Rise of Women Lobbyists
Authors: Strickland James M. , Stauffer Katelyn E.
Published: May 2021

Despite a growing body of literature examining the consequences of women’s inclusion among lobbyists, our understanding of the factors that lead to women’s initial emergence in the profession is limited. In this study, we propose that gender diversity among legislative targets incentivizes organized interests to hire women lobbyists, and thus helps to explain when and how women emerge as lobbyists. Using a comprehensive data set of registered lobbyist–client pairings from all American states in 1989 and 2011, we find that legislative diversity influences not only the number of lobby contracts held by women but also the number of former women legislators who become revolving-door lobbyists. This second finding further supports the argument that interests capitalize on the personal characteristics of lobbyists, specifically by hiring women to work in more diverse legislatures. Our findings have implications for women and politics, lobbying, and voice and political equality in the United States.

Postoperative coagulopathic bleeding is common in cardiac surgery and is associated with increased morbidity and mortality. Ideally, real-time information on in-vivo coagulation should be available. However, up to now it is unclear which perioperative coagulation parameters can be used best to accurately identify patients at increased risk of bleeding. The present study analyzed the associations of perioperative fibrinogen concentrations and whole blood viscoelastic tests with postoperative bleeding in 89 patients undergoing combined cardiac surgery procedures. Postoperative bleeding was recorded until 24 hours after surgery. Regression analyses were performed to establish associations between blood loss and coagulation parameters after cardiopulmonary bypass including a prediction model with known confounding factors for bleeding. Coagulation tests show large changes over the perioperative course with the strongest coagulopathic deviations from baseline after cardiopulmonary bypass. After adjustment for multiple confounders, viscoelastic clot strength instead of fibrinogen concentration showed a similar performance for 24 hour blood loss and a better performance for 6 hour blood loss. This makes intraoperative viscoelastic testing a useful tool to strengthen early clinical decision-making with the potential to reduce perioperative blood transfusions.
Covering COVID: Journalists’ Stress and Perceived Organizational Support While Reporting on the Pandemic
Authors: Hoak Gretchen
Published: May 2021

The COVID-19 pandemic forced unprecedented changes upon journalists in the United States as they attempted to cover the story while adhering to the same stay-at-home orders as the rest of the public. This study used organizational support theory to investigate the stress associated with the logistics of coverage early in the pandemic and how perceived organizational support played a role in either alleviating or adding to that stress. In total, 222 journalists responded to a survey sent out during the first few weeks of the stay-at-home orders issued across the United States. Results revealed varying degrees of logistical support provided by news organizations with nearly one quarter receiving no supplies, technology, or extra training at all. Greater perceived organizational support was associated with lower levels of stress and higher levels of work commitment. Female journalists and those who were younger and less experienced felt significantly more stress associated with pandemic coverage.

This study aims to describe Facebook users’ beliefs toward physical distancing measures implemented during the Coronavirus disease (COVID-19) pandemic using the key constructs of the health belief model. A combination of rule-based filtering and manual classification methods was used to classify user comments on COVID-19 Facebook posts of three public health authorities: Centers for Disease Control and Prevention of the United States, Public Health England, and Ministry of Health, Singapore. A total of 104,304 comments were analyzed for posts published between 1 January, 2020, and 31 March, 2020, along with COVID-19 cases and deaths count data from the three countries. Findings indicate that the perceived benefits of physical distancing measures ( n = 3,463; 3.3%) was three times higher than perceived barriers ( n = 1,062; 1.0%). Perceived susceptibility to COVID-19 ( n = 2,934; 2.8%) was higher compared with perceived severity ( n = 2,081; 2.0%). Although susceptibility aspects of physical distancing were discussed more often at the start of the year, mentions on the benefits of intervention emerged stronger toward the end of the analysis period, highlighting the shift in beliefs. The health belief model is useful for understanding Facebook users’ beliefs at a basic level, and it provides a scope for further improvement.
What Types of Exercise Are More Effective in Reducing Obesity and Blood Pressure for Middle-Aged Women? A Systematic Review With Meta-Analysis
Authors: Park Seong-Hi , Kim Chul-Gyu
Published: May 2021

Background:

A systematic review was performed to identify the types of physical activities effective as interventions in preventing metabolic syndrome in middle-aged women.

Methods:

Electronic databases (MEDLINE, EMBASE, the Cochrane Library, and CINAHL) served as the data sources. Cochrane’s Risk of Bias 2 was applied to assess the risk of bias of the randomized controlled trials. Meta-analyses were performed on selected studies using Review Manager 5.3. Thirty-one trials enrolling 2,202 participants were included.

Results:

Compared to controls, the effects of physical activity were indicated by pooled mean differences, which were −0.57 kg for body weight, −0.43 kg/m2 for body mass index, −1.63 cm for waist circumference, −4.89 mmHg for systolic blood pressure (BP), and −2.71 mmHg for diastolic BP. The effects were greater on the measurements of waist circumference and BP than on body weight and BMI. The types of physical activities were further analyzed according to sub-groups. Only aerobic exercise did not affect body weight and resistance exercise did not significantly change any results. Contrarily, combined exercises significantly reduced measurements of waist circumference and BP.

Conclusion:

This review can provide valuable information for research and implementation of measures to prevent metabolic syndrome in middle-aged women.
Collision tumor of sebaceous carcinoma and squamous cell carcinoma of the eyelid: Case report
Authors: Wang Jin-Jhe , Lee Kam-Fai , Chen Chau-Yin
Published: May 2021

Background:

Collision tumors are rare clinical entities that two heterogeneous neoplasms are concurrently adjacent to each other at the same location. The association of a squamous cell carcinoma and a malignant adnexal tumor is even infrequent.

Case presentation:

The case of a 79-year-old woman having a slow-growing and painless tumor on the left lower eyelid was presented. The lesion, about 15 mm in diameter, was nodular, irregular, and yellow-discolored. Histopathologic and immunohistochemical findings disclosed concurrence of sebaceous carcinoma as well as squamous cell carcinoma in one specimen. Wide excision of the tumor with frozen section control and eyelid reconstruction were performed. Oncologic survey revealed no other lesion. At 6-month follow-up, no evidence of recurrence or metastasis was presented.

Conclusion:

Collision tumor composed of sebaceous carcinoma and squamous cell carcinoma in eyelid may be the first case described in the literature. For increasing accuracy of diagnosis and management, a thorough clinical examination and detailed histopathologic analysis, along with multidisciplinary discussion, are prerequisites.
