Fair Treatment for All: Testing the Predictors of Workplace Inclusion in a Canadian Police Organization
Authors: Workman-Stark Angela L.
Published: October 2020

The growing diversification of the workforce demands that organizational leaders create workplaces in which individuals have a sense of belonging and are valued for their unique contributions. However, beyond the contributions of certain types of leadership, there is insufficient understanding of the factors that impact experiences of workplace inclusion. Using survey data collected from a Canadian police organization ( N = 488) in the spring of 2018, this study examined whether organizational justice (i.e., fair treatment) was positively associated with workplace inclusion, and whether psychological safety mediated the justice–inclusion relationship. The results of structural equation modelling (SEM) revealed that organizational justice was significantly related to inclusion. Organizational justice was also found to indirectly influence perceptions of inclusion, through psychological safety. In other words, when people were treated fairly, they were more likely to indicate their workplace was psychologically safe, which in turn contributed to feelings of inclusion. Finally, the study findings indicated that personal characteristics, including gender, race and occupational role influenced individual experiences of inclusion.
Natural Language Analysis and the Psychology of Verbal Behavior: The Past, Present, and Future States of the Field
Authors: Boyd Ryan L. , Schwartz H. Andrew
Published: October 2020

Throughout history, scholars and laypeople alike have believed that our words contain subtle clues about what we are like as people, psychologically speaking. However, the ways in which language has been used to infer psychological processes has seen dramatic shifts over time and, with modern computational technologies and digital data sources, we are on the verge of a massive revolution in language analysis research. In this article, we discuss the past and current states of research at the intersection of language analysis and psychology, summarizing the central successes and shortcomings of psychological text analysis to date. We additionally outline and discuss a critical need for language analysis practitioners in the social sciences to expand their view of verbal behavior. Lastly, we discuss the trajectory of interdisciplinary research on language and the challenges of integrating analysis methods across paradigms, recommending promising future directions for the field along the way.
Duchamp Within and Against Lacan
Authors: Alliez Éric
Published: October 2020

Critical reception of Marcel Duchamp since the 1970s has tended to elevate him into the very figure of the Artist he sought to attack. One aspect of this domestication has involved neglecting Duchamp’s fin de siècle ‘eroticism’ with its sexual innuendos and double-entendres. Yet this very readymade vulgarity allows us to recover a Duchamp still capable of disrupting the genres of Art and the gendered Artist, by revealing a theory embedded in his work which continually reverses and displaces phallocentrism in a game consisting of the confusion of genders and genres. We argue that Duchamp’s disruption of the discursive typologies of the genre of art can be profitably read through this apparently trivial sexualized wordplay, particularly in the transgender passage into Rrose Sélavy. Reading this aspect of Duchamp after, i.e. within and against, Lacan demonstrates how Duchamp’s singular regime of signs governed by equivocity and indetermination subverts the ‘phallic function’ of the signifier.
On the Contemporary Relevance of Jürgen Habermas’ Social Theory
Authors: Winter Rainer
Published: October 2020

This introduction discusses the contemporary relevance of Jürgen Habermas’ social theory following the publication of his recent work, Auch eine Geschichte der Philosophie (2019). It deals with his key topics and interventionist style of thinking. The essence of Habermas’ critical theory is its unwavering commitment to the utopia of communicative reason.
Synthesis Fe3O4/Talc nanocomposite by coprecipition-ultrasonication method and advances in hexavalent chromium removal from aqueous solution

Published: October 2020

The Fe3O4/Talc nanocomposite was synthesized by the coprecipitation-ultrasonication method. The reaction was carried out under a inert gas environment. The nanoparticles were characterized by X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), fourier-transform infrared spectroscopy (FT-IR) and vibrating sample magnetometry techniques (VSM), the surface area of the nanoparticles was determined to be 77.92 m2/g by Brunauer-Emmett-Teller method (BET). The kinetic data showed that the adsorption process fitted with the pseudo-second order model. Batch experiments were carried out to determine the adsorption kinetics and mechanisms of Cr(VI) by Fe3O4/Talc nanocomposite. The adsorption process was found to be highly pH-dependent, which made the material selectively adsorb these metals from aqueous solution. The isotherms of adsorption were also studied using Langmuir and Freundlich equations in linear forms. It is found that the Langmuir equation showed better linear correlation with the experimental data than the Freundlich. The thermodynamics of Cr(VI) adsorption onto the Fe3O4/Talc nanocomposite indicated that the adsorption was exothermic. The reusability study has proven that Fe3O4/Talc nanocomposite can be employed as a low-cost and easy to separate.
Political difference and polarization in the family: The role of (non)accommodating communication for navigating identity differences
Authors: Warner Benjamin R. , Colaner Colleen Warner , Park Jihye
Published: October 2020

This study joins the relatively modest literature examining the effects of political disagreement in the family. We consider the effects of communication accommodation on shared family identity in the context political disagreement. To do this, we utilize survey responses from a quota-stratified sample of participants in an online panel ( N = 833) taken immediately after the contentious 2016 presidential election. We find that more disagreement and more affective polarization are associated with less communication accommodation and that shared family identity suffers as a result. Furthermore, our findings reveal that respecting divergent values is the most influential communication accommodation strategy and is also among the most adversely affected by political differences in the family. We conclude that political disagreement in the family reduces the likelihood of communication that is respectful of differences in political values, but that this accommodation strategy is crucial to reduce the deleterious consequences that political differences can have on family relationships.
Orthographic activation in spoken word recognition of L2 phonological variants
Authors: Han Jeong-Im , Kim Song Yi
Published: October 2020

The present study investigated the influence of orthographic input on the recognition of second language (L2) spoken words with phonological variants, when first language (L1) and L2 have different orthographic structures. Lexical encoding for intermediate-to-advanced level Mandarin learners of Korean was assessed using masked cross-modal and within-modal priming tasks. Given that Korean has obstruent nasalization in the syllable coda, prime target pairs were created with and without such phonological variants, but spellings that were provided in the cross-modal task reflected their unaltered, nonnasalized forms. The results indicate that when L2 learners are exposed to transparent alphabetic orthography, they do not show a particular cost for spoken word recognition of L2 phonological variants as long as the variation is regular and rule-governed.
Effect of dramatized health messages: Modelling predictors of the impact of COVID-19 YouTube animated cartoons on health behaviour of social media users in Nigeria
Authors: Onuora Chijioke , Torti Obasi Nelson , Ezeah Gregory Herbert , Gever Verlumun Celestine
Published: October 2020

Previous studies on the impact of Internet-powered media on health promotion have often neglected the relationship between message recall and health behaviour. Such neglect makes it look as though exposure to media messages automatically leads to recall. Also, other studies appear to have paid less attention to understanding if the perception of the existence or otherwise of a public health issue actually influences the effectiveness of health intervention. In the current study, the authors suggest a model that takes into consideration these existing gaps. They examined 470 social media users who were exposed to YouTube animated cartoons on COVID-19 using an example from a developing country. The authors found, among others, that perception concerning the realness of COVID-19 was the greatest contributing factor in predicting the effectiveness of YouTube animated cartoons on health behaviour. The scholarly theoretical and practical contributions of the findings are explored.
Caring precariously: An interpretive description of palliative care and welfare worker perspectives on end of life carers navigating social welfare
Authors: Bindley Kristin , Lewis Joanne , Travaglia Joanne , DiGiacomo Michelle
Published: October 2020

Background:

Caring at end-of-life is associated with financial burden, economic disadvantage, and psychosocial sequelae. Health and social welfare systems play a significant role in coordinating practical resources and support in this context. However, little is known about social policy and interactions with public institutions that shape experiences of informal carers with social welfare needs at end-of-life.

Aim:

To explore ways in which palliative care and welfare sector workers perceive and approach experiences and needs of the carers of people with life-limiting illnesses who receive government income support or housing assistance, in an area of recognised socioeconomic disadvantage.

Design:

An interpretive descriptive study employed in-depth, qualitative interviews to explore participants’ reflections on working with carers of someone with a life-limiting illness. Data were analysed using the framework approach.

Setting/participants:

Twenty-one workers employed within three public services in Western Sydney were recruited.

Results:

Workers articulated understandings of welfare policy and its consequences for carers at end-of-life, including precariousness in relation to financial and housing circumstances. Identified resources and barriers to the navigation of social welfare needs by carers were categorised as personal, interpersonal and structural.

Conclusions:

Caring at end-of-life while navigating welfare needs was seen to be associated with precariousness by participants, particularly for carers positioned in vulnerable social locations. Findings highlighted experiences of burdensome system navigation, inconsistent processes and inequity. Further exploration of structural determinants of experience is needed, including aspects of palliative care and welfare practice and investment in inter-agency infrastructure for supporting carers at end-of-life.
End-of-life care after the legal introduction of advance directives: A qualitative study involving healthcare professionals and family caregivers of patients with amyotrophic lateral sclerosis
Authors: Cipolletta Sabrina , Reggiani Margherita
Published: October 2020

Background:

Advance care planning and advance directives play a key role in the care of life-threatening illnesses such as amyotrophic lateral sclerosis.

Aim:

The aim of the present study is to explore how the introduction of these features by law improves the experience of end-of-life care.

Design:

Five focus groups were conducted in Italy 1 year after the new law on advance directives was introduced.

Setting/Participants:

Purposive sampling was used to recruit 24 health professionals and 23 family caregivers of patients with amyotrophic lateral sclerosis, for a total of 47 participants.

Results:

The thematic analysis, conducted through the use of ATLAS.ti software, identified four thematic areas: best practices, managing difficulties, care relationships and proposals. The results indicated a lack of organization, collaboration and continuity on the part of healthcare services and professionals, a lack of information on palliative care, advance care planning, and advance directives. End-of-life care is often left to the good will of the individual professional. Difficulties can also derive from ethical dilemmas concerning end-of-life decision-making and from a lack of communication and relationships between health professionals, patients and their families.

Conclusion:

The introduction of advance directives by law has not been sufficient to improve end-of-life care. In order to make legal regulation effective, the organization of healthcare services needs to be improved and clearer procedures have to be implemented and shared with patients and families.
Relative signal intensity on time-of-flight magnetic resonance angiography as a novel indicator of aggressive presentation of intracranial dural arteriovenous fistulas
Authors: Ryu Bikei , Sato Shinsuke , Mochizuki Tatsuki , Niimi Yasunari
Published: October 2020

Asymptomatic dural arteriovenous fistulas (DAVFs) with cortical venous reflux (CVR) are now more commonly encountered. However, patients with an incidental onset may have a less aggressive clinical course. It is desirable to explore methods and indicators to predict the clinical outcomes. This study investigates whether the relative signal intensity (rSI) of the draining vessels on the time-of-flight magnetic resonance angiography is related to clinical behavior in patients with intracranial DAVFs. We retrospectively reviewed 36 intracranial DAVFs. The patients were categorized as those with either aggressive-presentation or non-aggressive-presentation (n = 16 and 20, respectively). The rSIs of the shunt points, affected sinuses, and veins with CVR were compared between the two groups. The two groups were not significantly different in terms of rSIs of the shunt points and affected sinuses (p = 0.37 and 0.41, respectively). However, a significant positive correlation was observed in the rSI of the veins with CVR between the aggressive and non-aggressive behavior groups (p < 0.0001). The rSI of the veins with CVR could serve as a reliable indicator of aggressive behavior in intracranial DAVFs, and its optimal cutoff value was 1.63 with high sensitivity and specificity for predicting aggressive behavior (area under the curve, 0.909).
T2 mapping of the acetabular cartilage in infants and children with developmental dysplasia of the hip
Authors: Lu Zhao , Pan Shinong , Wang Baijun , Liu Jiahui , Gao Tianyang , Lyu Xiaohong
Published: October 2020

Background

T2 mapping is useful for evaluating the cartilage matrix.

Purpose

To determine the variations in the acetabular cartilage T2 relaxation values between healthy individuals and those with developmental dysplasia of the hip (DDH).

Material and Methods

Thirty-three patients with unilateral DDH underwent 3-T magnetic resonance imaging (MRI) between January 2018 and February 2019. Fifteen volunteers (30 hips) were enrolled as controls. T2 values were measured with the T2 mapping sequence in all layers and were equally divided into three layers (deep, middle, and superficial) with equal thickness. We calculated the mean T2 relaxation values for the full thickness, deep, middle, and superficial layers and compared the values between the different groups. In addition, the inter- and intra-observer agreements were calculated.

Results

The T2 relaxation values in the DDH arm were significantly lower in the middle, superficial, and full thickness layers compared with those of the volunteers and contralateral hips. The T2 relaxation values of the deep layers showed no significant difference between the different groups. The acetabular cartilage T2 relaxation values increased from the deep layer to the superficial layer in the control and contralateral groups. Both inter- and intra-observer agreements were good.

Conclusion

MRI T2 mapping may help to diagnose developmental disorders of the acetabular cartilage matrix in infants and children with DDH. Abnormal acetabular cartilage T2 relaxation values may be due to the extraordinary stress load of the femoral head.
Analysis of pancreatic fistula risk in patients with laparoscopic pancreatoduodenectomy: what matters
Authors: Nong Kate , Zhang Yue , Liu Shengyong , Yang Yue , Sun Donglin , Chen Xuemin
Published: October 2020

Objective

To analyse potential risk factors for postoperative pancreatic fistula (POPF).

Methods

A retrospective study on risk factors for POPF was conducted in patients undergoing laparoscopic pancreatoduodenectomy. Basic characteristics, and preoperative, intraoperative and postoperative patient data were collected and analysed.

Results

A total of 268 patients were enrolled in this study, including 54 patients with POPF following surgery (POPF incidence, 20.15%). Univariate analysis indicated that patient’s age, body mass index (BMI), preoperative bilirubin level, pancreas texture, and drainage fluid amylase level on day 1 following surgery were associated with POPF. Multiple logistic regression analysis indicated that preoperative bilirubin level ≥170 µmol/l, soft pancreas texture, BMI ≥25, and age ≥65 years were independent risk factors associated with POPF.

Conclusions

For patients with preoperative bilirubin level ≥170 µmol/l, soft pancreas texture, BMI ≥25 and age ≥65 years, clinically relevant measures should be taken as early as possible for the prophylaxis of POPF.
Factors influencing early recurrence of hepatocellular carcinoma after curative resection
Authors: Zhu Yu , Gu Lingling , Chen Ting , Zheng Guoqun , Ye Chao , Jia Weidong
Published: October 2020

Objective

To identify the factors influencing early recurrence in patients with hepatocellular carcinoma (HCC) after curative resection.

Methods

Clinical data for 99 patients with HCC undergoing curative resection were analyzed. The clinicopathological factors influencing early recurrence were analyzed by Cox regression.

Results

Twenty-five of 99 patients (25.3%) suffered from early recurrence. There were significant differences between patients with and without recurrence in terms of tumor diameter, tumor capsular integrity, and preoperative alpha fetoprotein level. Cox regression analysis revealed that a tumor diameter >2.6 cm and preoperatively increased total bilirubin (TBL) level were risk factors for postoperative recurrence, while tumor capsular integrity had a protective effect on postoperative recurrence. After adjusting for preoperative TBL level and tumor capsular integrity, the risk of HCC recurrence was markedly increased in line with increasing tumor diameter in a non-linear manner.

Conclusion

Tumor diameter >2.6 cm and preoperatively increased TBL level are associated with a higher risk of early recurrence after curative resection in patients with HCC, while tumor capsular integrity is associated with a lower risk of early recurrence.
Spontaneous rupture of the right quadriceps tendon in a patient undergoing long-term hemodialysis: a case report
Authors: Zhang Hongjie , Lin Zengping , Zhong Jiping , Nie Darong , Gao Shan , Zhang Jiafang
Published: October 2020

Spontaneous unilateral quadriceps tendon rupture is an uncommon injury that is generally associated with chronic kidney disease and metabolic disorders. The current case involved a 50-year-old man with a painful right knee that he was unable to extend as a result of minor trauma sustained in an accident. Physical examination combined with radiographic and ultrasonographic investigations led to a diagnosis of quadriceps tendon rupture of the right knee. The patient had a 7-year history of hemodialysis for treatment of chronic kidney disease, leading to secondary hyperparathyroidism. He underwent successful tendon repair surgery, and his right knee was immobilized with splints for 6 weeks postoperatively. He gradually resumed full weight bearing and then normal walking.
Risk of Clostridium tetani infection in an elderly patient following hemorrhoid ligation
Authors: Lai Xiaofei , Hosyanto Felycia Fernanda , Xu Lei
Published: October 2020

Tetanus after gastrointestinal surgery is an extremely rare but very dangerous disease caused by infection with Clostridium tetani. Tetanus can occur due to bacterial infection during surgery or dressing change, or the bacteria may exist in the patient’s intestines and be discharged with feces. This report describes a 71-year-old woman who developed tetanus 3 days after a hemorrhoidal ligation. Clinicians need to be aware of symptoms of C. tetani infection that might present in patients who have undergone gastrointestinal procedures.
Role of platelet-rich plasma in the treatment of osteoarthritis: a meta-analysis
Authors: Ren Haijiang , Zhang Shouwei , Wang Xuejie , Li Zehui , Guo Wenlai
Published: October 2020

Objective

The clinical efficacy of platelet-rich plasma (PRP) in the treatment of osteoarthritis remains controversial. In this paper, we evaluated the clinical efficacy of PRP in the treatment of osteoarthritis using meta-analysis, providing evidence for the selection of clinical treatment options.

Methods

We performed a computer-based search of PubMed, Embase, and the Cochrane Library databases to retrieve articles using the search terms “platelet-rich plasma”, “osteoarthrosis”, and “knee joint”. Quality evaluation and data extraction were performed. The combined effect was assessed using RevMan 5.3 software.

Results

Five randomized controlled trials, involving 320 patients, were included in this study. No significant differences were observed in the International Knee Documentation Committee score, visual analog scale (VAS) score, or the absolute value of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score between the experimental and control groups. The absolute value of the VAS score and change in the WOMAC score were significantly decreased and patient satisfaction was increased in the experimental group, as compared with the control group.

Conclusion

The findings of this meta-analysis suggest that intra-articular injection of PRP is an effective treatment for osteoarthritis that can reduce post-operative pain, improve locomotor function, and increase patient satisfaction.
Motion-corrected free-breathing late gadolinium enhancement combined with a gadolinium contrast agent with a high relaxation rate: an optimized cardiovascular magnetic resonance examination protocol
Authors: Yan Cui , Hu Junjiao , Li Yanyu , Xie Xingzhi , Zou Zhimin , Deng Qiyu , Zhou Xiaoyue , Bi Xiaoming , Zeng Mu , Liu Jun
Published: October 2020

Objective

This prospective study investigated the feasibility of an optimized cardiovascular magnetic resonance (CMR) examination protocol using the motion-corrected (MOCO), balanced steady-state free precession (bSSFP), phase-sensitive inversion recovery (PSIR) sequence combined with a gadolinium contrast agent with a high relaxation rate in patients who cannot hold their breath.

Methods

Fifty-one patients with heart disease underwent CMR examinations twice and these were performed with different late gadolinium enhancement (LGE) imaging sequences (fast low-angle shot [FLASH] sequence vs. MOCO sequence) and different gadolinium contrast agents (gadopentetate dimeglumine vs. gadobenate dimeglumine) with a 48-hour interval. LGE image quality, total time spent in the whole study, and time taken to perform LGE imaging were compared for the two CMR examinations.

Results

LGE images with the MOCO bSSFP PSIR sequence showed significantly higher image quality compared with those with the segmented FLASH PSIR sequence. There was a significant difference between the total scan time for the two examinations and different LGE sequences.

Conclusions

The MOCO bSSFP PSIR sequence effectively improves the quality of LGE images. Changing the CMR scanning protocol by combining the MOCO bSSFP PSIR sequence with a gadolinium contrast agent with a high relaxation rate effectively shortens the scan time. Clinical trial registration number: ChiCTR-ROC-17013978.
A highly unusual case of osmotic demyelination syndrome and extrapontine myelinolysis in a 3-month-old infant with Bartter syndrome
Authors: Gargano Giancarlo , Manfredi Marco , Pedori Simona , Di Dio Francesco , Spagnoli Carlotta , Frattini Daniele
Published: October 2020

Bartter syndrome (BS) is a rare autosomal recessive renal tubular disorder characterized by acute electrolyte imbalance, and similarly, osmotic demyelination syndrome (ODS) is a rather rare complication occurring during electrolyte imbalance. The pathological features of ODS include central pontine myelinolysis and extrapontine myelinolysis (EPM), which consist of severe damage to the myelin sheath of neurons. ODS is very rare in children. We describe a case of a 3-month-old infant with ODS and EPM associated with undiagnosed BS. ODS developed because of a sudden change in electrolyte levels and osmolality caused by acute dehydration during a gastrointestinal infection episode. Undiagnosed, untreated, and non-balanced BS was the cause of the neurological complication. Our patient represents the first case of ODS in BS, the ninth case of ODS in an infant less than one year old, and the third case of isolated EPM in such a young patient. This case report reminds us that in rare diseases, young patients tend to have genetic components.
A Wavelet-based hybrid multi-step Wind Speed Forecasting model using LSTM and SVR
Authors: K U Jaseena , Kovoor Binsu C
Published: October 2020

Wind energy, one of the greatest progressing renewable energy sources, becomes more significant for sustainable development and environmental protection. Its intermittent nature makes accurate and reliable predictions very challenging. Currently, hybrid models are extensively employed for wind speed forecasting and have been established to perform superior to traditional single forecast models. Hence, in this paper, a hybrid multi-step wind speed forecasting framework that combines the features of Wavelet Transform (WT), Long Short Term Memory (LSTM), and Support Vector Regression (SVR) is proposed. The prediction accuracy of the model is enhanced by denoising the dataset using wavelet transforms, which decomposes the data into low and high-frequency sub-series. The low-frequency sub-series is forecasted using LSTM network, and the high-frequency sub-series using SVR. Each forecasting outcomes are summed up to get the final forecasting results. The simulation results reveal that the forecast accuracy has significantly improved for the proposed wavelet-based hybrid model.
Visual Simultaneous Localization and Mapping with Applications to Monitoring of Underground Transportation Infrastructure
Authors: Daneshgaran Fred , Marangi Antonio , Bruno Nicola , Lizzio Fausto , Mondin Marina , Olia Khashayar
Published: October 2020

This paper presents the results of the development, design, and implementation of a visual simultaneous localization and mapping (SLAM) system for autonomous real-time localization with application to underground transportation infrastructure (UTI) such as tunnels. Localization is achieved in the absence of any global positioning system (GPS) or auxiliary system. The indoor localization system is a necessary element of a fully autonomous platform for the detection of cracks and other anomalies on the interior surfaces of tunnels and other UTI. It can be used for tagging of high-resolution sensor data obtained with low-cost prototype data acquisition platforms previously developed. Visual based SLAM has been used as the core element in an architecture employing a commercial off-the-shelf (COTS) ZED stereo camera from Stereolabs. To achieve real-time operation, an NVIDIA Jetson TX2 massively parallel graphics processing unit (GPU) was used as the core computational engine employing two different software libraries. We achieved localization at 5 frames per second (FPS) using ORBSLAM2 open-source software library, and the much lighter, but proprietary, ZED SDK was able to deliver a performance at nearly 60 FPS. To assess the accuracy of the relative localization system, we conducted several tests at 30 FPS and reported on the resulting error variances that were found to be consistently very small. Finally, we conducted several tests in a tunnel in the Los Angeles county area and confirmed the applicability of the method for monitoring UTI.

Published: October 2020

Despite the burden of sexual assault on college campuses, few effective prevention programs exist. Understanding the socio-ecological context in which sexual assaults occur may illuminate novel pathways to augment prevention. We examined data from 349 students at two inter-connected urban universities who completed a population-based survey ( N = 1,671) and described at least one incident of sexual assault victimization. Using latent class analysis of 13 incident, relationship, and social context characteristics, we identified three types of sexual assaults: Incapacitation, Known Assailant, both Drinking; Verbal Coercion, Partner/Friend, Private; and Unwanted Touching, Stranger, Public. Incapacitation, Known Assailant, both Drinking incidents often involved survivor incapacitation with someone known to the victim following a party. Verbal Coercion, Partner/Friend, Private incidents often involved verbal coercion and intimate partners, with others rarely present prior to the assault. Unwanted Touching, Stranger, Public incidents often involved unwanted touching and strangers in a public place. Findings suggest three distinct sexual assault types, defined by different incident, relational, and socio-contextual factors, and reinforce the importance of disaggregating sexual assault to tailor prevention programs more effectively. Campus policy-makers and providers should be aware that each type of assault may require different prevention approaches.

Slave Women and Their Descendants among the Upper Classes in Tetouan, Morocco (1859–1956): Between Recognition and Conflict
Authors: Mateo Dieste Josep Lluís
Published: October 2020

In the Arab world, the recognized children of elite men and slave women could adopt the status of their father, ignoring the slave origin of the mother, owing to a system of patrilineal transmission. This regime co-existed with negative stereotypes toward slaves and blackness, despite the very fact that—as this study of notable families in Tetouan between 1859 and 1956 demonstrates—skin color was not the determinant factor to form part of this group. Rather, it was based on the social definition of filiation, leading to legal disputes between family members to delineate the boundaries of kinship.
Radiographic Methods Are as Accurate as Magnetic Resonance Imaging for Graft Sizing Before Lateral Meniscal Transplantation
Authors: Ambra Luiz Felipe , Kaleka Camila Cohen , Debieux Pedro , Almeida Julio Cesar , Shah Nehal , Cohen Moises , Gomoll Andreas
Published: October 2020

Background:

Accurate allograft matching is deemed critical for meniscal transplantation; thus, precise measurements are essential to correctly calculate meniscal size. Several methods for meniscal sizing have been described, but there remains a discussion on which is the most accurate for the lateral meniscus.

Purpose:

To compare the accuracy of radiographic, anthropometric, and magnetic resonance imaging (MRI) methods of determining width and length of the lateral meniscus with actual dimensions after anatomic dissection.

Study Design:

Controlled laboratory study.

Methods:

Ten fresh-frozen human cadaveric knees without any evidence of meniscal or ligamentous injury were primarily imaged using radiography and MRI and subsequently underwent dissection to assess the anatomic size of each meniscus. Four methods were used to predict the size of the lateral menisci: anthropometric, radiographic (Pollard and Yoon), and MRI. Absolute differences in length and width between actual and predicted sizes were determined.

Results:

The anatomic lateral meniscal width and length were 33.01 ± 4.25 mm (mean ± SD; range, 24.84-40.18 mm) and 31.41 ± 5.06 mm (range, 25.2-40.05 mm), respectively. Regarding width, the anthropometric method demonstrated an absolute difference from anatomic measurement significantly greater when compared with the Pollard technique and MRI ( P = .002). Regarding length, the Pollard method presented an absolute difference significantly greater than all other techniques ( P = .003). In terms of the ability to measure width and length, MRI accurately predicted meniscal size within 10% of the anatomic size in 65% of measurements, the Yoon method in 54%, and the Pollard method in 20% ( P = .01). Radiographs tended to overestimate the true size of the lateral meniscus, while the anthropometric technique overestimated width in all specimens.

Conclusion:

This study demonstrated that MRI and the Yoon radiographic method are comparable in terms of accuracy for graft sizing before lateral meniscal transplantation. While MRI is useful, a contralateral MRI is required, which makes the Yoon radiographic method recommended given the ease and cost advantage. The original Pollard technique and the anthropometric method are not recommended.

Clinical Relevance:

Over- and undersizing of meniscal transplants has been implicated in graft failure. Therefore, increasing the reliability of preoperative meniscal measurements is deemed important for the success of meniscal allograft transplantation.
Clinical Outcomes of Patients With Anterior Shoulder Instability and Glenolabral Articular Disruption Lesions: A Retrospective Comparative Study
Authors: Davey Martin S. , Hurley Eoghan T. , Colasanti Christopher A. , Scanlon John P. , Gaafar Mohamed , Hogan Brian A. , Pauzenberger Leo , Mullett Hannan
Published: October 2020

Background:

Anterior shoulder instability is a common clinical condition that often requires surgical stabilization. Glenoid labral tears are often associated with instability, with glenolabral articular disruption (GLAD) lesions occasionally being identified arthroscopically during repair, particularly in collision athletes.

Purpose:

To evaluate the clinical outcomes and recurrence rates in patients who had GLAD lesions and underwent arthroscopic Bankart repair (ABR) and compare them with a control group without GLAD lesions.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

A retrospective review of patients who underwent ABR with GLAD lesions, by a single surgeon between July 2012 and March 2017, was performed. Additionally, these were pair matched in a 2:1 ratio for age, sex, sport, and level of play with a control group who underwent ABR without GLAD lesions. Return to sport, the level of return, and the timing of return were assessed. The visual analog scale (VAS) for pain score, Rowe score, Shoulder Instability–Return to Sport after Injury (SIRSI) score, and Subjective Shoulder Value (SSV) were evaluated.

Results:

The study included a total of 66 patients (22 and 44 patients for the GLAD and control groups, respectively), with a mean age of 25.8 years and a mean follow-up of 66 months. Overall, there was no significant difference in any of the clinical outcome scores (VAS, Rowe, SIRSI, and SSV) utilized for the GLAD and control groups ( P > .05 for all). Similarly, there was no significant difference in the total rate of return to play (90.9% vs 88.6%; P > .99) or return at the same/higher level (68.2% vs 72.7%; P = .78). There was no significant difference in timing of return to play (6.3 ± 6.6 months vs 6.4 ± 2.5 months; P = .98). There were 3 cases (13.6%) requiring further surgery (1 revision stabilization, 1 arthroscopic release, and 1 rotator cuff repair) in the GLAD group and 2 cases (4.5%) requiring further surgery (both revision stabilization) in the control group; the difference was not statistically significant ( P = .32).

Conclusion:

After arthroscopic repair, patients with GLAD lesions had similar midterm outcomes when compared with a control group without GLAD lesions.

Published: October 2020

Background:

Arthroscopic superior capsule reconstruction (SCR) was developed to restore shoulder superior stability, muscle balance, and function in patients with irreparable posterior-superior rotator cuff tears.

Purpose:

To assess the effects of concomitant subscapularis tendon tear, which may reduce glenohumeral stability and force coupling, on clinical outcomes of SCR for irreparable posterior-superior rotator cuff tears.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

In total, 193 patients with irreparable posterior-superior rotator cuff tears underwent arthroscopic SCR using fascia lata autograft between 2007 and 2015. They were allocated to 3 groups: group 1, no subscapularis tear (160 patients); group 2, reparable subscapularis tear, which underwent arthroscopic repair (26 patients); and group 3, irreparable subscapularis tear (7 patients). American Shoulder and Elbow Surgeons (ASES) and Japanese Orthopaedic Association (JOA) scores, visual analog scale (VAS) score for pain, active shoulder range of motion (ROM), muscle strength (manual muscle test), and acromiohumeral distance were evaluated before surgery and at final follow-up (mean, 3 years, 7 months; range, 2-11 years). Postoperative complications were assessed.

Results:

In groups 1 and 2, ASES, JOA, and VAS scores and shoulder ROM and muscle strength improved significantly after SCR with subscapularis repair ( P < .001). SCR in group 3 significantly improved ASES, JOA, and VAS scores ( P < .001), whereas shoulder ROM and muscle strength did not increase significantly. Postoperative acromiohumeral distance was significantly smaller in group 3 (5.7 ± 2.9 mm [mean ± SD]) than group 2 (9.1 ± 2.3 mm) ( P = .002). Group 3 had a significantly higher rate of graft tear ( P < .001) and postoperative infection ( P < .001) than group 1.

Conclusion:

The presence of subscapularis tendon tear affects clinical outcomes and complication rates after SCR. The reparability of the subscapularis affects superior glenohumeral stability; therefore, an intact subscapularis or reparable subscapularis tendon tear is the best indication for arthroscopic SCR in patients with irreparable posterior-superior rotator cuff tendon tears.
Commodification 2.0: How Does Spotify Provide Its Services for Free?
Authors: Kasap Orçun , Yalcintas Altug
Published: October 2020

It is widely argued that applications on the internet, especially the software on which the Web 2.0 platforms perform, cause transaction costs to diminish and help such platforms provide their services for free. In this paper, we challenge this argument. We claim that there is no causation between the diminishing transaction costs and the free supply of online services. Focusing our attention on Spotify, we argue that a new economy of data extraction, which we call Commodification 2.0, favors giant internet corporations in such a way that they appropriate the value that online users collaboratively produce. Music artists, however, are either underpaid or not paid at all.

Continuous occupational exposure to spent engine oil (SEO) poses physiological risks to humans, especially to automobile mechanics. This study investigated the physiological effects of SEO-contaminated soil in a male Wistar rat model. Animals were dermally exposed to soil contaminated with SEO for 120 consecutive days and compared with rats exposed to uncontaminated soil (negative control). Heavy metal (lead (Pb), nickel (Ni), zinc, and cadmium (Cd)) accumulations, hematology, biochemical (aspartate aminotransferase (AST), alanine aminotransferase, alkaline phosphatase (ALP), urea, and creatinine) parameters, sperm morphology, and histopathology (liver, kidney, lungs, brain, skin, and testis) were evaluated as end points. Results revealed that the heavy metals in SEO-contaminated soil are far greater than the World Health Organisation permissible limits, with significant ( p < 0.05) increases of Pb and Ni present in the brain, and Pb and Cd in the serum compared with the uncontaminated soil for the negative control. Only significant ( p < 0.05) values were observed in the lymphocytes, activities of AST and ALP, and sperm abnormalities of the exposed rats compared with those used for the negative control. Histopathological changes were not evident in the brain but lesions were observed in the liver, kidney, lungs, skin, and testis of the exposed rats. Results herein suggest that the constituents of SEO may elicit harmful physiological changes to humans who are directly exposed to them.
Effectively engaging physicians in system change

What started as a prospective study to support clinical leaders and inform strategies to engage their peers in system change was impacted due to a rapidly evolving political agenda amid a pandemic, affecting both organizations and outcomes. Participants in this mixed methods study in one Local Health Integrated Network (LHIN) in Ontario included clinical leaders and community physicians over a period of 14 months. As the provincial government shifted regional healthcare governance from LHINs to Ontario Health Teams, there was an increase in the engagement of community physicians and leaders identified a noticeable culture shift with the potential to drive change. High-performing healthcare systems are dependent not only on physicians who can lead and engage others but a government that can acknowledge this.

Additive manufacturing has facilitated the fabrication of orthopedic metal implants with interconnected pores. Recent reports have indicated that a pore size of 600 μm is beneficial for material-induced osteogenesis. However, the complete removal of the metal powder from such small pores of implants is extremely difficult especially in electron beam melting (EBM). We therefore developed a new type of Ti-6Al-4V implant with lattice-shaped interconnected pores measuring 880–1400 μm, which allowed for the easy removal of metal powder. This implant was fabricated by EBM and treated with NaOH, CaCl2, heat, and water (ACaHW treatment) to render the metal surface bioactivity. In the present study, the mechanical and chemical property of the implants and the biocompatibility were evaluated. The SEM and micro-CT images demonstrated the 3D interconnectivity of the porous structures. The average porosity of the porous titanium implant was 57.5%. The implant showed maximum compressive load of 78.9 MPa and Young's modulus of 3.57 GPa which matches that of human cortical bone. ACaHW treatment of the porous Ti-6Al-4V implants induced apatite formation in simulated body fluid in vitro. The ACaHW-treated porous implants harvested from rabbit femoral bone showed direct bonding of bone to the metal surface without interposition of fibrous tissue. The porous ACaHW-treated implant had a higher affinity to the bone than the untreated one. The mechanical strength of implant fixation assessed using the push-out test was significantly higher in the ACaHW-treated implant than in untreated one. FE-SEM analysis and EDX mapping after push-out test of solid implants showed a lot of bone tissue patches on the surface of the ACaHW-treated implant. These results suggest that the new ACaHW-treated Ti-6Al-4V implant with lattice-shaped interconnected pores is a superior alternative to conventional materials for medical application.
Social Anxiety as a Consequence of Non-consensually Disseminated Sexually Explicit Media Victimization

The purpose of this qualitative study was to explore consequences of the non-consensual dissemination of sexually explicit media (NCDSEM) for survivors, with an emphasis on how NCDSEM may impact social relationships and social anxiety. One-on-one telephone interviews with ( N = 17) self-identified survivors of NCDSEM were conducted between May and December 2019. Interviews were analyzed using a flexible coding methodology. There were five main ways in which participants described consequences of NCDSEM: (a) fear of going out in public, (b) fear of engaging in relationships, (c) fear of applying to jobs, (d) fear of seeking help, and (e) influencing depression and feelings of anxiety. These findings suggest that, for some people, NCDSEM victimization may influence whether and how they subsequently socialize with other people.
Knitting With and for Others: Repercussions on Motivation

Knitting is an activity that generates well-being and that can be undertaken in a group. It is characterized by the creation of a final piece, which may have different purposes. The aims of this study were to explore the effects of knitting in a natural group, as well as examining the impact that the purpose of the piece created might have on the motivation to knit. A mixed methodology was used with one group of knitters, under two conditions: knitting for oneself and for others. The data was collected through a volitional questionnaire, personal diaries and semi-structured interviews. The participants expressed that knitting gave them a sense of well-being and relaxation. Carrying out this activity in a group also enabled them to have the possibility of learning and teaching. Knitting for others is more meaningful than knitting for oneself because they knitted for people they cared for.
