Published: March 2021

AbstractObjectiveAlthough digital health tools (DHTs) are a promising alternative and effective strategy to deliver cancer care and support, their role in health promotion among cancer survivors remains relatively unexplored. We aimed to investigate the acceptability and impact of DHT for health promotion in cancer survivors.MethodsData was pooled from cycle three of the fifth edition of the Health Information National Trends Survey. Logistic regressions were conducted to evaluate differences between cancer survivors and the general population regarding ownership, usage, and perceived usefulness of DHT for health management. Regression models were used to identify sociodemographic predictors of DHT usage among cancer survivors.ResultsOverall, cancer survivors were as likely as the general population to own and use DHT (e.g., health apps, wearable devices) for their care and they were likely to find these tools beneficial in tracking their health and communicating with healthcare providers. Cancer survivors who had health applications installed on their mobile device were more likely to meet national recommendations for diet (fruit and vegetable consumption) and strength training than those without health apps. Age, income, and education level were significant sociodemographic predictors of DHT ownership and usage.ConclusionCancer survivors own and use DHT at similarly high rates to the general population, highlighting the potential for utilizing DHT to expand access and continuity of care in the growing and vulnerable oncology population. With increasing use of DHT in healthcare, future research that targets digital access disparities in cancer survivors from low SES is essential.
Inverse Hooke's law and complementary strain energy in coupled strain gradient elasticity
Authors: Nazarenko Lidiia , Glüge Rainer , Altenbach Holm 
Published: March 2021

AbstractThe inverse Hooke's law and complementary strain energy density has been examined in the context of the theory of coupled gradient elasticity for second gradient materials. To this end, it was assumed that the potential energy density is a quadratic form of the strain and of the second gradient of displacement. Existence of the coupling term significantly complicates the problem. To avoid this complication the equation for the potential energy density was transformed in order to present it as an uncoupled quadratic form of a modified strain and the second gradient of displacement or of the strain and a modified second gradient of displacement. These transformations, which is in essence a block matrix diagonalization, lead to a decoupling of strains and strain gradient in the potential energy density and makes it possible to determine tensorial relations for the compliance tensors of fourth‐, fifth‐ , and sixth‐rank. Both modifications result in the same compliance tensors and are valid for an arbitrary material symmetry class. In the case of hemitropic materials, the compliance tensors have the same symmetry and the same form as the stiffness tensors and are characterized by eight independent constants, namely the two classical isotropic constants, five constants in the strain gradient part and one constant in the coupling term. Explicit expressions for these eight parameters are obtained from the tensorial relations for the compliance tensors and are compared with the direct solution of a linear system for the compliance's. All three solutions are identical, what we consider as a verification of the presented results.

AbstractThe current study was designed to determine the concentrations of toxic metals (Ni, Pb and Cr) in feathers of birds collected from four regions of NE Pakistan. Feather samples of birds (House Crow, Common Myna and House Sparrow) were collected from different areas. Atomic absorption spectrophotometer was used to determine the concentration of metals in feathers. Analysis of the data revealed that concentrations of Pb and Cr were significantly different (p < 0.05) among bird species, whereas no difference (p > 0.05) was detected among bird species (house crow, common myna and house sparrow) for Ni. A significant difference was found for the concentration of Pb and Ni in all the four studied regions. Whereas, non-significant difference was found in all the studied regions for the concentrating of Cr. It was revealed that there is significant rising concentration of metals (Pb, Cr) in feathers of birds in Azad Kashmir.

Abstract
Purpose
Systematic reviews report return to play (RTP) within 5.8 months (range, 3–8) following the Latarjet procedure, but the factors that influence RTP remain unknown. The present study aimed to report the rate and time of return to play (RTP) during the first 8 months following the Latarjet procedure, and to determine the influence of sport type or patient characteristics.

Methods
The authors retrospectively collected the records of patients that underwent Latarjet procedures for anterior shoulder instability between 2015 and 2017. Patients were excluded if they had any concomitant rotator cuff tendon lesions, or previous ipsilateral shoulder surgery. The authors retrieved patient demographics, time from injury to surgery, type of sport practiced (overhead/non-overhead, contact/non-contact), as well as pre- and postoperative Western Ontario Shoulder Instability index (WOSI), Shoulder Instability-Return to Sport After Injury index (SIRSI), and Rowe score.

Results
A total of 217 patients (217 shoulders) were eligible for inclusion, comprising 184 males and 33 females, aged 26.8 ± 7.3 years at index surgery. The main sport practiced prior to surgery involved overhead (n = 173, 80%) and/or contact (n = 152, 70%) activities. By 8 month follow-up, 158 patients (73%) resumed their main sport, at a mean of 5.1 ± 1.5 months. Multivariable analysis revealed that RTP was more likely in patients with higher preoperative Rowe score (OR, 1.02; p = 0.024) and SIRSI score (OR, 1.02; p = 0.008).

Conclusions
By 8 months following the Latarjet procedure, 73% of patients had resumed their main sport. The likelihood of RTP was significantly associated with preoperative Rowe and SIRSI scores, but not with sport type.

The impact of procedural and distributive justice on satisfaction and manufacturing performance: a replication of Lindquist (1995) with a focus on the importance of common metrics in experimental design
Authors: Lindquist Tim M. , Rausch Alexandra 
Published: March 2021

AbstractThis paper replicates Lindquist’s (Lindquist, Journal of Management Accounting Research 7:122–147, 1995) seminal research introducing the concepts of justice to the accounting literature. We use organizational justice theory, as did he, to replicate his study and, in doing so, question some findings of partial replications and extensions done over the past 25 years. We do this because work built off his study has challenged some of his findings. These challenges, we believe, have resulted from most researchers using different research metrics than did Lindquist. Many of these extensions have also used a mental-based task, instead of a manual-based one, in their experiments. We believe this constrains the ability to draw inferences and conclusions from this subsequent research. We further believe this constraint extends to much of the experimental research in the social sciences.In our research we replicate exactly Lindquist’s (Lindquist, Journal of Management Accounting Research 7:122–147, 1995) operationalizations of voice and vote and measure dependent outcomes for four of the same conditions he investigated. In contrast to most of other follow-up studies, we find, as did Lindquist, that having a voice only leads to significantly enhanced satisfaction with high-stretch targets, as compared to having a vote only or no input. We also corroborate Lindquist’s (Lindquist, Journal of Management Accounting Research 7:122–147, 1995) result that having a voice only leads to significantly greater satisfaction with the experimental task, as compared to participants with a vote only or no input. Additionally, unlike Lindquist (Lindquist, Journal of Management Accounting Research 7:122–147, 1995), we find participants allowed only a voice significantly outperform participants with a vote only and no input. We thus support Lindquist’s findings of a fair process effect for voice and perceptions of pseudo-participation related to vote.

Abstract
Objectives
Radiologists’ perception is likely to influence the adoption of artificial intelligence (AI) into clinical practice. We investigated knowledge and attitude towards AI by radiologists and residents in Europe and beyond.

Methods
Between April and July 2019, a survey on fear of replacement, knowledge, and attitude towards AI was accessible to radiologists and residents. The survey was distributed through several radiological societies, author networks, and social media. Independent predictors of fear of replacement and a positive attitude towards AI were assessed using multivariable logistic regression.

Results
The survey was completed by 1,041 respondents from 54 mostly European countries. Most respondents were male (n = 670, 65%), median age was 38 (24–74) years, n = 142 (35%) residents, and n = 471 (45%) worked in an academic center. Basic AI-specific knowledge was associated with fear (adjusted OR 1.56, 95% CI 1.10–2.21, p = 0.01), while intermediate AI-specific knowledge (adjusted OR 0.40, 95% CI 0.20–0.80, p = 0.01) or advanced AI-specific knowledge (adjusted OR 0.43, 95% CI 0.21–0.90, p = 0.03) was inversely associated with fear. A positive attitude towards AI was observed in 48% (n = 501) and was associated with only having heard of AI, intermediate (adjusted OR 11.65, 95% CI 4.25–31.92, p < 0.001), or advanced AI-specific knowledge (adjusted OR 17.65, 95% CI 6.16–50.54, p < 0.001).

Conclusions
Limited AI-specific knowledge levels among radiology residents and radiologists are associated with fear, while intermediate to advanced AI-specific knowledge levels are associated with a positive attitude towards AI. Additional training may therefore improve clinical adoption.

Key Points
• Forty-eight percent of radiologists and residents have an open and proactive attitude towards artificial intelligence (AI), while 38% fear of replacement by AI.
• Intermediate and advanced AI-specific knowledge levels may enhance adoption of AI in clinical practice, while rudimentary knowledge levels appear to be inhibitive.
• AI should be incorporated in radiology training curricula to help facilitate its clinical adoption.
On nonparametric regression for bivariate circular long-memory time series
Authors: Beran Jan , Steffens Britta , Ghosh Sucharita 
Published: March 2021

AbstractWe consider nonparametric regression for bivariate circular time series with long-range dependence. Asymptotic results for circular Nadaraya–Watson estimators are derived. Due to long-range dependence, a range of asymptotically optimal bandwidths can be found where the asymptotic rate of convergence does not depend on the bandwidth. The result can be used for obtaining simple confidence bands for the regression function. The method is illustrated by an application to wind direction data.
Least-thickness symmetric circular masonry arch of maximum horizontal thrust
Authors: Cocchetti Giuseppe , Rizzi Egidio 
Published: March 2021

AbstractThis analytical note shall provide a contribution to the understanding of general principles in the Mechanics of (symmetric circular) masonry arches. Within a mainstream of previous research work by the authors (and competent framing in the dedicated literature), devoted to investigate the classical structural optimization problem leading to the least-thickness condition under self-weight (“Couplet-Heyman problem”), and the relevant characteristics of the purely rotational five-hinge collapse mode, new and complementary information is here analytically derived. Peculiar extremal conditions are explicitly inspected, as those leading to the maximum intrinsic non-dimensional horizontal thrust and to the foremost wide angular inner-hinge position from the crown, both occurring for specific instances of over-complete (horseshoe) arches. The whole is obtained, and confronted, for three typical solution cases, i.e., Heyman, “CCR” and Milankovitch instances, all together, by full closed-form explicit representations, and elucidated by relevant illustrations.

Published: March 2021

Abstract
Introduction
Glioblastoma multiforme (GBM) is a primary malignant brain tumour characterized by a very low long-term survival. The aim of this study was to analyse the distribution of treatment modalities and their effect on survival for GBM cases diagnosed in Germany between 1999 and 2014.

Methods
Cases were pooled from the German Cancer Registries with International Classification of Diseases for Oncology, third edition (ICD-O-3) codes for GBM or giant-cell GBM. Three periods, first (January 1999–December 2005), second (January 2006–December 2010) and a third period (January 2011–December 2014) were defined. Kaplan–Meier plots with long-rank test compared median overall survival (OS) between groups. Survival differences were assessed with Cox proportional-hazards models adjusted for available confounders.

Results
In total, 40,138 adult GBM cases were analysed, with a mean age at diagnosis 64.0 ± 12.4 years. GBM was more common in men (57.3%). The median OS was 10.0 (95% CI 9.0–10.0) months. There was an increase in 2-year survival, from 16.6% in the first to 19.3% in the third period. When stratified by age group, period and treatment modalities, there was an improved median OS after 2005 due to treatment advancements. Younger age, female sex, surgical resection, use of radiotherapy and chemotherapy, were independent factors associated with better survival.

Conclusion
The inclusion of temozolomide chemotherapy has considerably improved median OS in the older age groups but had a lesser effect in the younger age group of cases. The analysis showed survival improvements for each treatment option over time.

Abstract
Purpose
Previous studies on the effect of tumor location on overall survival in glioblastoma have found conflicting results. Based on statistical maps, we sought to explore the effect of tumor location on overall survival in a population-based cohort of patients with glioblastoma and IDH wild-type astrocytoma WHO grade II–III with radiological necrosis.

Methods
Patients were divided into three groups based on overall survival: < 6 months, 6–24 months, and > 24 months. Statistical maps exploring differences in tumor location between these three groups were calculated from pre-treatment magnetic resonance imaging scans. Based on the results, multivariable Cox regression analyses were performed to explore the possible independent effect of centrally located tumors compared to known prognostic factors by use of distance from center of the third ventricle to contrast-enhancing tumor border in centimeters as a continuous variable.

Results
A total of 215 patients were included in the statistical maps. Central tumor location (corpus callosum, basal ganglia) was associated with overall survival < 6 months. There was also a reduced overall survival in patients with tumors in the left temporal lobe pole. Tumors in the dorsomedial right temporal lobe and the white matter region involving the left anterior paracentral gyrus/dorsal supplementary motor area/medial precentral gyrus were associated with overall survival > 24 months. Increased distance from center of the third ventricle to contrast-enhancing tumor border was a positive prognostic factor for survival in elderly patients, but less so in younger patients.

Conclusions
Central tumor location was associated with worse prognosis. Distance from center of the third ventricle to contrast-enhancing tumor border may be a pragmatic prognostic factor in elderly patients.
What drives reindeer management in Finland towards social and ecological tipping points?
Authors: Landauer Mia , Rasmus Sirpa , Forbes Bruce C. 
Published: March 2021

AbstractReindeer management (RM) in northern Fennoscandia is an example of social-ecological systems (SESs) providing social, cultural, ecological, and economic values. Changing climate and pasture conditions and societal changes continue to transform the operational environment of RM. These key drivers, and resulting transformations including alternative SES states, have not been studied in detail before. Our comprehensive literature review and interviews with herders reveal that land use, climate change, and governance drive the emergence of SES tipping points. The basis of successful RM depends on the quantity and quality of pastures to secure animal fitness. However, intensive forestry, extreme weather, and predators constrain the availability of forage and suitable calving grounds. Maintaining RM by means of predation compensation mechanisms and regular supplementary winter feeding to adapt to changes brought about by land use and warming climate comprises an alternative system state. However, if negative impacts increase remarkably or rapidly and compensatory mechanisms become insufficient, long-term impacts on system identity, and even local collapses, are expected. Although some environmental and societal changes are perceived as pressures by herders, they can be beneficial for other livelihoods in the region. Therefore, our study raises questions for future studies on social justice, such as who has the right to decide what constitutes a desirable system state, or what collaborative efforts to maintain RM in Fennoscandia would entail. Our work is applicable also in other Arctic/sub-Arctic regions where nature-based livelihoods, such as small-scale forestry and agriculture, hunting, traditional fishing, and gathering are practiced.

Abstract
Background
The aim of this study was to identify serum miRNAs that discriminate early gastric cancer (EGC) samples from non-cancer controls using a large cohort.

Methods
This retrospective case–control study included 1417 serum samples from patients with EGC (seen at the National Cancer Center Hospital in Tokyo between 2008 and 2012) and 1417 age- and gender-matched non-cancer controls. The samples were randomly assigned to discovery and validation sets and the miRNA expression profiles of whole serum samples were comprehensively evaluated using a highly sensitive DNA chip (3D-Gene®) designed to detect 2565 miRNA sequences. Diagnostic models were constructed using the levels of several miRNAs in the discovery set, and the diagnostic performance of the model was evaluated in the validation set.

Results
The discovery set consisted of 708 samples from EGC patients and 709 samples from non-cancer controls, and the validation set consisted of 709 samples from EGC patients and 708 samples from non-cancer controls. The diagnostic EGC index was constructed using four miRNAs (miR-4257, miR-6785-5p, miR-187-5p, and miR-5739). In the discovery set, a receiver operating characteristic curve analysis of the EGC index revealed that the area under the curve (AUC) was 0.996 with a sensitivity of 0.983 and a specificity of 0.977. In the validation set, the AUC for the EGC index was 0.998 with a sensitivity of 0.996 and a specificity of 0.953.

Conclusions
A novel combination of four serum miRNAs could be a useful non-invasive diagnostic biomarker to detect EGC with high accuracy. A multicenter prospective study is ongoing to confirm the present observations.
