History trapped into eternity: Kinesis and stasis in The Leopard
Authors: Arnavas Francesca
Published: March 2021

The complex and often paradoxical representation of time and history in Giuseppe Tomasi di Lampedusa’s The Leopard has its roots in an existential vision which is charged with different meanings and shadowed by a dark pessimism. In order to convey his peculiar perspective, Lampedusa uses specific narrative techniques, transforming earthly elements into eternal symbols. In turn, Luchino Visconti, in his movie adaptation of the novel, translates these multi-layered symbols into visual representations, emphasising some of them more than others, and giving even more substance to the material as a vehicle of complex, theoretical reflections. The analysis of the emblematic role of landscape, interiors, objects and animals in The Leopard, both in the written approach and the visual re-interpretation, offers new insights into a novel and a movie which have always divided critics, who have alternatively considered them a celebration of immobilism or a faithful historical depiction.
Structure-property relations of a natural composite: Bamboo guadua angustifolia, under impact and flexural loads
Authors: Rua José J , Buchely Mario F , Monteiro Sergio Neves , Colorado Henry A
Published: March 2021

In this work a natural fiber composite material, the Guadua Angustifolia Kunth from the family of Bamboo is investigated as a suitable alternative for solutions for impact applications, load-bearing, and other structural applications. Since this type of Bamboo grows faster than wood and requires less water and area to reach maturity and be able to crop, it is a competitive, economically, and environmentally solution when is compared to other construction materials. The Bamboo species of interest is a natural one from Colombia and will be evaluated in flexural behavior and under impact response to understand the material subjected under fast loading. Flexural samples were cut parallel to bamboo axial fibers to obtain the highest impact strength. The flexural tests and scanning electron microscopy characterization were included for microstructure analysis. Additionally, compression at high strain rates was characterized by a split-Hopkinson pressure bar (SHPB). Results show flexural strength of about 70 MPa. The impact analysis showed a tough material with very similar values to Charpy notched and dynamic instrumented impact tests.
The Trini Sing-Song: Sociophonetic variation in Trinidadian English prosody and differences to other varieties
Authors: Meer Philipp , Fuchs Robert
Published: March 2021

The current study provides a phonetic perspective on the questions of whether a high degree of variability in pitch may be considered a characteristic, endonormative feature of Trinidadian English (TrinE) at the level of speech production and contribute to what is popularly described as ‘sing-song’ prosody. Based on read and spontaneous data from 111 speakers, we analyze pitch level, range, and dynamism in TrinE in comparison to Southern Standard British (BrE) and Educated Indian English (IndE) and investigate sociophonetic variation in TrinE prosody with a view to these global F0 parameters. Our findings suggest that a large pitch range could potentially be considered an endonormative feature of TrinE that distinguishes it from other varieties (BrE and IndE), at least in spontaneous speech. More importantly, however, it is shown that a high degree of pitch variation in terms of range and dynamism is not as much characteristic of TrinE as a whole as it is of female Trinidadian speakers. An important finding of this study is that pitch variation patterns are not homogenous in TrinE, but systematically sociolinguistically conditioned across gender, age, and ethnic groups, and rural and urban speakers. The findings thus reveal that there is a considerable degree of systematic local differentiation in TrinE prosody. On a more general level, the findings may be taken to indicate that endonormative tendencies and sociolinguistic differentiation in TrinE prosody are interlinked.

Published: March 2021

The aim of this research was to conduct a risk assessment and management of psychological, structural, social and economic determinants (PSSED) in a suicide attempt. The sample consisted of 353 individuals who had a recorded history of suicidal attempt; and 20 professional individuals by purposive sampling method within a descriptive cross-sectional design. Worksheets for RAM and AHP were used for data collection in this study. The rate of suicide attempt was 7.21 per 100,000 population in this study. Analysis showed that depression and mental disorders; personality disorders; family problems; socio-cultural and economic problems; lack of awareness; and low level of education have a high level of risk for suicide attempts. Psychiatric and psychological services; awareness and knowledge of life skills; medical services to dysfunctional families; development of community-based planning for PSSED of suicide; and employment and entrepreneurship services may lower suicide attempt risk.
Diverging Disparities: Race, Parental Income, and Children’s Math Scores, 1960 to 2009
Authors: Conwell Jordan A.
Published: March 2021

In recent decades, the black–white test score disparity has decreased, and the test score disparity between children of high- versus low-income parents has increased. This study focuses on a comparison that has, to date, fallen between the separate literatures on these diverging trends: black and white students whose parents have similarly low, middle, or high incomes (i.e., same income or race within income). To do so, I draw on three nationally representative data sets on 9th or 10th graders, covering 1960 to 2009, that contain information on students’ math test scores. I find that math test score disparities between black and white students with same-income parents are to black students’ disadvantage. Although these disparities have decreased since 1960, in 2009 they remained substantively large, statistically significant, and largest between children of the highest-income parents. Furthermore, family and school characteristics that scholars commonly use to explain test score disparities by race or income account for markedly decreasing shares of race-within-income disparities over time. The study integrates the literatures on test score disparities by race and income with attention to the historical and continued structural influence of race, net of parental income, on students’ educational experiences and test score outcomes.

Globally, sexually transmitted infections are recognized as a public and reproductive health challenge. The study determined the prevalence, co-infection, and risk factors associated with HBV, HCV, HIV, and Syphilis infections among pregnant women receiving antenatal care in rural health facilities in Ebonyi State, Nigeria. A retrospective study was conducted from January to December 2018 in 8 primary healthcare facilities using antenatal records of all the 4657 pregnant women who attended ANC within the period. Data were analyzed using descriptive and inferential statistics with IBM SPSS statistics version 20 and hypotheses tested at P < .05. The findings indicated a medium prevalence of HBV (4.1%), a high prevalence of HCV (4.1%) and syphilis (1.8%), and a low prevalence of HIV (0.9%). An overall co-infection rate of 0.623% that was not significant ( P > .05) was observed. Also, prevalence was more among the younger mothers (<20 years), those with secondary education. And the history of blood transfusion was significantly associated with HBV and HCV prevalence (χ2 = 7.865; P = .05*), 11.8%. conclusively, due to medium HBV prevalence and a high prevalence of HCV and syphilis observed, attention should be paid to blood screening before transfusion by health workers. Relevant stakeholders should provide intensive health education and appropriate free treatment services particularly for younger mothers and the less educated.
Conferring Kinship: Examining Fictive Kinship Status in a Black Adolescent’s Natural Mentoring Relationship
Authors: Scott Edward D. , Deutsch Nancy L.
Published: March 2021

This case study examined the way an adolescent Black boy extended his kinship network as a part of navigating and demonstrating agency in mentoring relationships with nonparental adults. We purposively selected one participant, Bodos, from the sample of a larger mixed-method study involving youth, aged 12 to 18 years, in the southeastern United States. Drawing on narrative methodology, we used a holistic-content approach to analyze Bodos’ responses to semistructured interviews. Bodos used several narratives to describe his experiences. We offer three findings: (a) Fictive kinship is a positive feature of Black adaptive culture that can be leveraged by Black youth as a tool for creating a distinct relational dynamic with their mentors, (b) adolescent Black boys possess skills and knowledge that both preexist and emerge within positive mentoring relationships, and (c) youth agency and expectations manifest in mentoring relationships to inform and influence those adults’ significance. This case study furthers the field’s understanding of how cultural practices can positively influence relational development and create a unique relational context and experience.
Perceived Partner Responsiveness Forecasts Behavioral Intimacy as Measured by Affectionate Touch
Authors: Jolink Tatum A. , Chang Yen-Ping , Algoe Sara B.
Published: March 2021

Affectionate touch is an important behavior in close relationships throughout the lifespan. Research has investigated the relational and individual psychological and physical benefits of affectionate touch, but the situational factors that give rise to it have been overlooked. Theorizing from the interpersonal process model of intimacy, the current studies tested whether perceived partner responsiveness forecasts affectionate touch in romantic couples. Following a preliminary integrative data analysis ( N = 842), three prospective studies use ecologically valid behavioral (Studies 1 and 2) and daily (Studies 2 and 3) data, showing a positive association between perceived partner responsiveness and affectionate touch. Furthermore, in Study 3, we tested a theoretical extension of the interpersonal process of intimacy, finding that affectionate touch forecasts the partner’s perception of the touch-giver’s responsiveness the next day. Findings suggest affectionate touch may be an untested mechanism at the heart of the interpersonal process of intimacy.
The Experience of Being Fathered of Mexican-origin Male Youth
Authors: Sichling Florian
Published: March 2021

Fathers are important influences for the healthy development during the transition to adulthood of their children. Despite the theoretical acknowledgement of the reciprocal nature of the father–child relationship, we currently know very little about the experience of being fathered, particularly of immigrant male youth. Drawing on qualitative data from a study of Mexican-origin male youth in Chicago, this article documents the respondents’ experiences of their fathers as providers, role models and authority figures. The analysis reveals however, that the respondents experienced these rather traditional father roles in different ways, ranging from extreme violence and neglect to dedication and sacrifice, which in turn, led to rejection, modification, or emulation in their own conceptions of fatherhood. The findings urge researchers to examine the long-term effects of being fathered among immigrant youth and more specifically, how the experience of being fathered leads to different or similar patterns of fathering behavior later in life.

Published: March 2021

Introduction:

The aim of this study was to evaluate the incidence rate of technical failure of graft patency while performing intra-operative angiography after coronary artery bypass grafting.

Methods:

This prospective pilot study included 50 patients with multi-vessel coronary artery disease who underwent coronary artery bypass grafting, in addition to intra-operative angiographic graft assessments, on open-chest. Overall, 144 grafts and 160 distal anastomoses were assessed in a hybrid operating room.

Results:

Intra-operative angiography allowed the identification of 23 angiographic defects (15.9% of all grafts) in 22 patients (44%): three graft defects (2% of all grafts), 17 anastomotic defects (10.6% of all distal anastomoses), and three target artery errors (1.8% of all grafted arteries). Ten re-interventions (43.4%) were performed based on the angiographic defects detected. During the follow-up period, computed tomography angiography of the attached grafts at a mean of 224 days (range, 80–318 days) showed that all repaired grafts were patent. During surgery, the total mean dose of radiation was 1.848 ± 0.54 mSv (range, 0.78–3.4 mSv) per patient and investigation time was 19.4 ± 4.94 minute (range, 9–31 minute).

Conclusions:

Intra-operative angiography is a powerful tool allowing the identification of graft defects, anastomotic defects and target vessel errors. Assuming relatively low level of exposure to radiation and short investigation time, intra-operative angiography could be included in routine practice as safe procedure improving surgery quality.
Comparative analysis of differences between preoperative endoscopic biopsy and postoperative pathological examination for diagnosis of gastric intraepithelial neoplasia
Authors: Wu Yangqing , Sang Jianzhong , Zhou Jianbo , Fang Ying
Published: March 2021

Objective

This study was performed to compare the differences between preoperative endoscopic biopsy (PEB) and postoperative pathological examination (PPE) for diagnosis of gastric intraepithelial neoplasia (GIN).

Methods

From September 2016 to July 2019, 188 consecutive patients with GIN at Yuyao People’s Hospital were retrospectively analyzed. The 188 patients had 218 GIN lesions. All patients underwent PEB and either endoscopic submucosal dissection or surgical treatment. PPE was performed on pathological tissues that had been surgically removed.

Results

Among 138 cases of low-grade dysplasia (LGD) diagnosed by PEB, 46 were upgraded to high-grade dysplasia (HGD), 20 were upgraded to early gastric cancer (EGC), and 2 were downgraded to inflammation after PPE. Among 42 cases of HGD, 23 were upgraded to EGC, 2 were downgraded to LGD, and 2 were downgraded to inflammation after PPE. Among 38 cases of EGC, 1 was downgraded to HGD and 2 were downgraded to LGD after PPE. The original diagnosis was maintained after the operation in 120 cases of GIN.

Conclusion

Biopsy did not fully reflect the lesions of GIN. Biopsy review should be actively performed, and the lesions should be clarified by endoscopic submucosal dissection or surgery.
Effectiveness of Warning Piles on Driving Behavior on the Curve of Low-Grade Highway

Published: March 2021

To develop a scientific and practicable guideline for implementing warning piles on Chinese low-grade highways, it is necessary to study the effect of warning piles on driving performance in different road alignments and environments. Based on a driving simulator, this paper evaluates the effect of unilateral and bilateral warning piles on vehicle speed and lateral position on a two-lane rural highway curve with different road geometries. The results show a significant effect of bilateral warning piles on speed control, which becomes more obvious as the radius of the curve decreases and the superelevation increases. In sharp curves, vehicle speed increases rapidly in the second half of the curve, and bilateral warning piles could significantly control speed increase to prevent danger. Meanwhile, the effect of bilateral warning piles on keeping vehicles in a safer lane position is also statistically significant in the second half of the curve. With a decreasing radius and an increasing superelevation, the value of the maximum lateral position will increase. Bilateral warning piles could reduce the lateral position to keep the vehicle on a stable track. Moreover, bilateral warning piles could also perform better at night. This paper studies both unilateral and bilateral warning piles’ effects on driving behavior in different road geometries, thus providing a theoretical basis for the engineering application of warning piles.

Published: March 2021

Traditional route generation algorithms may result in many routes that few drivers choose in reality, whereas other route generation algorithms need to determine thresholds for route set generation but lack data support. To avoid invalid route generation, reduce computation time, and provide a scientific basis for the generation of navigation routes and traffic assignment, this paper confines the route set size by mining the spatial distribution range of route sets and the threshold of factors affecting route set generation. Global positioning system data are used to determine hotspots based on a hotspot origin–destination identification method. The route set spatial distribution range is mined by the standard deviational ellipse. Finally, the factors affecting the generation of route sets are selected, and the classification and regression trees algorithm is used to mine their thresholds. The results show that the spatial distribution range of route sets is elliptical, and the threshold values of the number of turns per kilometer for medium and long travel distances are 1.794 and 2.508, respectively. The maximum travel time per kilometer for long travel distance is 4.773 min. The maximum numbers of road intersections for short, medium, and long travel distance per kilometer are 1.648, 0.984, and 0.592, respectively. The implications of results on reducing the search range and time of the route set and their applications to traffic network design and route navigation are also discussed.
Arthroscopic Management of Femoroacetabular Impingement in Adolescents: A Systematic Review
Authors: Migliorini Filippo , Maffulli Nicola
Published: March 2021

Background:

Femoroacetabular impingement (FAI) is highly prevalent in adolescent athletes. There has been an increasing trend for arthroscopic surgery for FAI, and the results of several clinical studies on outcome after arthroscopic surgery for FAI are available.

Purpose:

To conduct a systematic review to investigate the role of arthroscopic management for FAI in adolescents.

Study Design:

Systematic review.

Methods:

This systematic review was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. In August 2020, PubMed, Scopus, Google Scholar, and EMBASE were accessed. All clinical trials concerning the arthroscopic treatment for adolescents with FAI were identified. Only studies on patients aged less than 18 years at the time of surgery reporting data over a minimum follow-up of 12 months were considered.

Results:

Data from 406 adolescents (470 procedures; mean age at surgery, 15.9 years; mean follow-up, 30.4 months) with FAI were retrieved. At a mean of 28.0 months of follow-up, 94% of the adolescents had already returned to sport. All the scores of interest were improved at the final follow-up: visual analog scale ( P = .01), modified Harris Hip Score ( P < .0001), Non-Arthritic Hip Score ( P = .03), Hip Outcome Score–Activities of Daily Living ( P = .01), Hip Outcome Score–Sport-Specific Subscale ( P < .0001), and Tegner score ( P < .0001). Complications occurred in 1.1% (5/470) of procedures, and revision arthroscopy was performed in 4.7% (22/470) of procedures.

Conclusion:

Arthroscopic surgery in adolescents with FAI achieves excellent outcomes and a high rate of return to sport, with rates of complication and revision surgery of 1% and 5%, respectively.
COVID-19 and Student Well-Being: Stress and Mental Health during Return-to-School

Published: March 2021

Students have been multiply impacted by the COVID-19 pandemic: threats to their own and their family’s health, the closure of schools, and pivoting to online learning in March 2020, a long summer of physical distancing, and then the challenge of returning to school in fall 2020. As damaging as the physical health effects of a global pandemic are, much has been speculated about the “second wave” of mental health crises, particularly for school-aged children and adolescents. Yet, few studies have asked students about their experiences during the pandemic. The present study engaged with over two thousand ( N = 2,310; 1,288 female; Mage = 14.5) 12- to 18-year-old Alberta students during their first few weeks of return-to-school in fall 2020. Students completed an online survey that asked about their perceptions of COVID-19, their fall return-to-school experiences (84.9% returned in-person), their self-reported pandemic-related stress, and their behavior, affect, and cognitive functioning in the first few weeks of September. The majority of students (84.9%) returned to school in person. Students reported moderate and equal concern for their health, family confinement, and maintaining social contact. Student stress levels were also above critical thresholds for 25% of the sample, and females and older adolescents (age 15–18 years) generally reported higher stress indicators as compared to males and younger (age 12–14 years) adolescents. Multivariate analysis showed that stress indicators were positively and significantly correlated with self-reported behavioral concerns (i.e., conduct problems, negative affect, and cognitive/inattention), and that stress arousal (e.g., sleep problems, hypervigilance) accounted for significant variance in behavioral concerns. Results are discussed in the context of how schools can provide both universal responses to students during COVID-19 knowing that most students are coping well, while some may require more targeted strategies to address stress arousal and heightened negative affect.
Who Survives and Who Does Not? The Rise and Decline of Personalized Parties
Authors: Yovcheva Teodora
Published: March 2021

The analysis of parties created around charismatic leaders is becoming more important in dynamic times when the mainstream parties are challenged by outsiders. Most of the research on personalized parties focuses on Western Europe although the phenomenon has significant implications for East European party systems. This article examines the development of two highly electorally successful personalized parties in Bulgaria: National Movement Simeon the Second (NDSV) and Citizens for European Development of Bulgaria (GERB), the incumbent ruling party. Their similar success but different paths of development provide a good basis for examining the stabilizing factors of personalized parties. The article fills a gap in the theoretical field by using information from qualitative interviews with high-level party members and proves that adoption of an organizational strategy is the key factor for survival. Examining a case of the emergence of personalized parties, the research finds that alongside charismatic leaders, investment in local branches and representation in localities are stabilizing factors when the popularity of the leader decreases and in this way secure the more stable development of the party.

Published: March 2021

This study aims at developing the screen-printed sensors as a viable means of depositing sensing tracks on composites for their on-line structural health monitoring. Conventional silk screen was employed in order to deposit a nano-composite solution comprising of a conductive nano-filler (carbon nano-particles) dispersed in a thermoplastic matrix (high density polystyrene) on laminated composite specimens. The solution was deposited using a squeegee and was allowed to dry. Commercially available metal foil strain gauges were also bonded alongside screen-printed sensor in order to compare the response of the screen-printed sensors with the commercially available strain gauges. The sensing ability of these screen-printed sensors was tested on a universal testing machine (MTS 810) in four-point bending configuration using a load cell of 100 kN. The sensor deposited using screen-printing technique underwent tensile loading at the lower side of the laminate. A data linearization and amplification module comprising of commercially available instrumentation amplifier (INA 118) was used in conjunction with data acquisition module (Keithley KUSB 3100). The results obtained show that the screen-printed sensors have higher gauge factors in tensile loading scenario with reasonably linear response as compared to traditional metal foil strain gauges. The ease of the deposition of a nano-composite solution via screen printing also makes the technique a viable alternative to the traditional resin bonded metal foil strain gauges which have to be bonded on the surface. Moreover, screen printing offers unlimited options for the development of smart composites in various configurations for a multitude of structural applications.
“I Suspect That the Pictures Are Stolen”: Romance Fraud, Identity Crime, and Responding to Suspicions of Inauthentic Identities
Authors: Cross Cassandra , Layt Rebecca
Published: March 2021

Romance fraud impacts the lives of thousands of people globally. Financial losses exceed millions of dollars each year and are steadily increasing annually. It occurs when an offender uses the guise of an intimate relationship to gain a financial advantage. Offenders use a variety of platforms and communications methods to target victims and develop the required trust and rapport to defraud them. As part of this process, offenders use false identities. This can be through the misappropriation of a genuine person’s identity, or it can be through the stealing of photos and other images of a genuine person to create a false or fictitious identity. In this way, romance fraud encompasses two categories of victims: those who lose money through a relationship and those who are subject to identity crime by romance fraud offenders. This article examines how individuals responded to suspicions of inauthentic identities to a person they were communicating with online. It uses romance fraud complaints lodged with Scamwatch (an Australian online fraud porting portal) between July 2018 and July 2019 (inclusive). The qualitative analysis indicates that many complainants used an internet search to verify or refute their suspicions about their partner. This yielded substantiated results in many cases and confirmed that the offender’s identity was not genuine. The article explores the implications for this victim-based detection strategy. In doing this, it argues that while effective for romance fraud victims, responses can further exacerbate the ongoing harms experienced by those whose identities have been compromised by romance fraud offenders. The article concludes with a discussion about the future effectiveness of internet searches to reduce romance fraud and the impact of this strategy on third parties whose identities are compromised by offenders.
Asystole Following Concomitant Intravenous Administration of Neostigmine and Dexmedetomidine in a Patient With Acute Colonic Pseudo-Obstruction
Authors: Bell Carolyn Magee , Procter Levi D. , Parli Sara E.
Published: March 2021

Acute colonic pseudo-obstruction (ACPO) is a condition characterized by acute dilation of the large bowel without evidence of mechanical obstruction that occurs in a variety of hospitalized patients with many predisposing factors. Management includes supportive care and limitation of offending medications with mainstays of treatment of neostigmine administration and colonic decompression. We report the case of a critically ill patient with ACPO who experienced bradycardia and a brief episode of asystole when receiving concomitant dexmedetomidine and neostigmine infusions but who later remained hemodynamically stable when receiving propofol and neostigmine infusions. The bradycardia and associated hemodynamic instability experienced while on dexmedetomidine and neostigmine infusions were rapidly corrected with atropine and cessation of offending agents. Because ACPO is encountered frequently and the use of dexmedetomidine as a sedative agent in the ICU is increasing, practitioners should be aware of the additive risk of bradycardia and potential for asystole with the combination of neostigmine and dexmedetomidine. Electronic drug interaction databases should be updated and drug information sources should include a drug-drug interaction between dexmedetomidine and neostigmine to reduce the likelihood of concomitant administration.
Psychological Empowerment and Job Satisfaction: A Meta-analytic Review
Authors: Mathew Jain , Nair Sridevi
Published: March 2021

Studies in the area of psychological empowerment have been on the rise since early 1990s. Given the large amount of information available, the researchers aim to consolidate findings, in order to arrive at a deeper understanding of the concept and its relation to job satisfaction of employees in organizations. The researchers have identified 50 studies, set in varied cultural and organizational settings. The data from these studies form the basis of the analysis in this paper. A meta-analysis of the findings of the chosen studies was conducted. This is followed by a systematic review of literature, to identify a few probable intervening variables that modify the relationship. The findings of the analysis suggest that the direct relation between psychological empowerment and job satisfaction is positive, strong and statistically significant. The study supports the validity of one of the earliest models explaining the relation. The paper establishes that the direct relation between psychological empowerment and job satisfaction is strong, positive and significant. The variations in the strength of the relationship is due to the presence of certain intervening variables like culture, age, educational qualification and experience.
Dissemination and Impact Amplified: How a Researcher–Reporter Collaboration Helped Improve the Criminal Justice Response to Victims With Untested Sexual Assault Kits
Authors: Lovell Rachel E. , Dissell Rachel
Published: March 2021

We present a case study of a researcher–reporter collaboration that formed from an initiative to address thousands of previously untested rape kits in one Midwestern (U.S.) jurisdiction. We explore this symbiotic partnership by examining (a) how and why it formed; (b) the outcomes, including extensive and public dissemination and a unique project that surveyed 294 Ohio law enforcement agencies to see what happened after the rape kits were tested (Ohio Rape Kit Survey Project); and (c) the impact that the partnership, dissemination, and larger initiative had in sparking demonstrable change in how the justice system and the general public responded to and engaged with the issue of untested rape kits and with victims of sexual assault. We conclude with larger takeaways from this collaboration for researchers and reporters but also provide a framework for how this type of collaboration can be leveraged to produce change for the greater good.
Building Bridges Between Researchers and Police Practitioners in Small and Midsize Law Enforcement Agencies in the United States

Published: March 2021

Although partnerships between researchers and police practitioners have increased over the last few decades in some of the largest police agencies in the United States, very few small agencies have engaged in a partnership with a researcher. Of the 18,000 local police agencies in the United States, small agencies with less than 25 sworn officers make up about three quarters of all police agencies. To support future collaborations between researchers and smaller police agencies, like those in Douglas County, Kansas, this article identifies challenges that researchers can address and explores how these relationships can benefit small police agencies across the United States.
Does Short-Term and Low-Dose N-Acetylcysteine Affect Oxidative Stress and Inflammation in The Liver Tissues of Diabetic Rats?
Authors: Genç Fatma , Peker Emine Gülçeri GÜLEÇ
Published: March 2021

Diabetes mellitus is a serious chronic disease in which the oxidant-antioxidant balance is impaired, causing many complications, including hepatopathy. In this study, the effects of short-term and low-dose N-acetylcysteine (NAC) administration on the biochemical, proinflammatory, and oxidative stress parameters in the liver tissue of diabetic rats were investigated. Twenty-four adult male Wistar albino rats weighing approximately 250–300 g were divided into 4 groups (n = 6): Control, Streptozotosin (STZ)-induced diabetes (DM), NAC treatment (60 mg/kg), and STZ-induced diabetes treated with NAC (DM+NAC; 60 mg/kg). NAC treatment was administered intraperitoneally as a single daily dose for 7 days. At the end of the experiment (3 weeks), blood and liver samples were collected for biochemical parameter analysis. Lipid peroxidation, antioxidant parameters, and nitric oxide (NOx) levels were determined by spectrophotometric method. Tissue inflammation parameters were evaluated by ELISA. Lipid peroxidation, proinflammatory cytokines, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) values increased significantly with diabetes. NAC treatment significantly decreased serum ALT and AST levels and proinflammatory cytokines in the diabetic group. Liver glutathione (GSH) and NOx levels increased significantly in the DM+NAC group ( p < 0.05). While NAC treatment reduced lipid peroxidation in the liver, it improved the inflammatory response and antioxidant status. The beneficial effect of NAC treatment may be due to its antioxidant activity and the resulting increased level of GSH. The results show that low-dose and short-term NAC treatment had a positive effect on oxidative damage and inflammation in liver tissue. NAC can be used as a potential antioxidant in diabetes to prevent hepatopathy.

Published: March 2021

Background:

There is paucity of data on objectively measured lung function abnormalities in Nigerian children using diagnostic testing methods such as spirometry. Such assessments could prompt early diagnosis and therapeutic interventions.

Methods:

This was a cross sectional study among children aged 6 to 12 years in South-Eastern Nigeria. We selected participants from one school using a multistage stratified random sampling technique. A structured respiratory questionnaire was administered to obtain necessary data. The lung functions of the children were measured by spirometry. We used Lower Limits of Normal (LLN) based on GLI reference equations for African-American and mixed ethnicities to define abnormal spirometry. We studied the association between the exposures and lung function using logistic regression/chi-squared tests.

Results:

A total of 145 children performed acceptable and repeatable tests. There were 73 males (50.3%), mean age of 9.13 years (+1.5) and age range 6 to 12 years. Frequency of respiratory symptoms was cough- 64 (44.1%) and wheeze in 19 (13.1%). Using GLI for African-Americans, fifty-five (37.9%) children had abnormal spirometryobstructive pattern in 40 (27.6%) and restrictive pattern in 15 (10.3%). The two references showed significant differences in interpretation of abnormality (χ2 = 72.86; P < .001). Respiratory symptom-wheeze was an independent determinant of abnormal lung function in this population.(OR = 0.31; 95%CI: 0.10–0.94; P = .04)

Conclusion:

There is a high burden of respiratory symptoms and abnormal spirometry among these children. The need for objective evaluation of lung function especially for children with respiratory symptoms is evident.

With the changing ethnic composition of the Australian population there has been a growing number of patients requiring transfusions of rarer blood types. People from ethnic minority groups are generally less likely to donate blood and this can lead to shortages for some patients from these communities. In this article we report the findings of a qualitative study of ethnic minority blood donors in Australia. We found that many of the motivators, facilitators, and barriers to donation raised by participants have been previously documented for non-ethnic minority donors, such as the desire to help others and the role of knowledge about blood donation. However, for participants these were enmeshed with, and shaped by, their culture and/or minority status. The findings demonstrate the multifaceted and interrelated nature of the motivators, facilitators, and barriers experienced by ethnic minorities to become and remain a blood donor in Australia.

Working holidays have emerged as an alternative form of travel that provides the opportunity to work to subsidise a holiday. Existing studies are limited, particularly those focused on working holidaymakers from Latin America. Utilising the push-pull framework, this study explores the motivations of Latin Americans undertaking working holidays and the reasons for selecting New Zealand as a working holiday destination. Thematic analysis of the data collected from sixteen Latin American working holidaymakers revealed six push factors for undertaking a working holiday and five pull factors for selecting New Zealand as their destination. The findings from this study contribute to current understandings of working holidaymakers, particularly from Latin America. While the results support earlier studies of working holidays, Latin American working holidaymakers’ interest in exploring business opportunities in destinations is a novel study finding.
Digital social work: Conceptualising a hybrid anticipatory practice
Authors: Pink Sarah , Ferguson Harry , Kelly Laura
Published: March 2021

While the use of digital media and technologies has impacted social work for several years, the Covid-19 pandemic and need for physical distancing dramatically accelerated the systematic use of video calls and other digital practices to interact with service users. This article draws from our research into child protection to show how digital social work was used during the pandemic, critically analyse the policy responses, and make new concepts drawn from digital and design anthropology available to the profession to help it make sense of these developments. While policy responses downgraded digital practices to at best a last resort, we argue that the digital is now an inevitable and necessary element of social work practice, which must be understood as a hybrid practice that integrates digital practices such as video calls and face-to-face interactions. Moving forward, hybrid digital social work should be a future-ready element of practice, designed to accommodate uncertainties as they arise and sensitive to the improvisatory practice of social workers.

We performed a cross-sectional study within a specialised respiratory inpatient unit assessing 25 nurses’ [85% female, 8.0 ± 7.9 (mean ± SD) years’ experience in nursing] confidence in providing inhaler device education using a self-reported questionnaire, and their competency (% correct steps) in using eight different inhaler devices. Sixteen percent of participants were ‘not confident’ providing inhaler education, while 84% were ‘moderately’ or ‘extremely’ confident. The mean (±SD)% correct steps for all devices was 47 ± 17%. There was no correlation between % correct steps and nursing years (r = 0.21, p = 0.31), or ‘confidence’ with providing inhaler education (r = 0.02, p = 0.91) but % correct steps strongly correlated with number of individual device prescriptions within the hospital in the preceding year (r = 0.78, p = 0.039). Most respiratory nurses felt confident in teaching inhaler technique but their overall demonstrated ability to correctly use inhalers was poor, especially for less frequently prescribed devices within our hospital. Regular assessment and ongoing education on correct inhaler technique for respiratory nurses is necessary to optimise all device usage by nurses, irrespective of experience or confidence.
Cytomegalovirus Disease, Short-Term Cardiovascular Events and Graft Survival in a Cohort of Kidney Transplant Recipients With High CMV IgG Seroprevalence
Authors: Díaz James S. , Jaimes Fabián A.
Published: March 2021

Introduction:

Both cytomegalovirus (CMV) infection and CMV disease have been linked with several long-term indirect effects in kidney transplant recipients. Research questions: We conducted a retrospective study to assess the association between cytomegalovirus disease and risks of death, shortterm cardiovascular events and graft loss in a cohort of renal transplant recipients.

Design:

The associations between CMV disease and death and cardiovascular events were determined using Cox regression models, while the association between viral disease and graft loss risk was analyzed through a competing risks regression according to the Fine and Gray method. Death with a functioning graft was considered as a competing risk event.

Results:

A total of 865 consecutive renal transplant recipients were included. The prevalence of seropositive donor/seronegative recipient (D+/R-) group was 89.9% with the remaining patients classified as seropositive recipient (R+). After median follow-up time of 24.4 months, CMV disease was not a risk factor for all-causes mortality (HR = 1.75; 95% CI 0.94-3.25), early cardiovascular events (HR = 0.54; 95% CI 0.16-1.82) or graft loss (subhazard ratio [the HR adjusted for competing risk of death with functioning graft] = 0.99; 95% CI 0.53-1.84).

Conclusions:

In this cohort with high prevalence of CMV IgG antibodies, we found no association between cytomegalovirus disease and risk of death or graft loss. The relationship between CMV and cardiovascular disease remains to be unraveled and probably corresponds to a multifactorial phenomenon involving individual risk factors and the immune response to infection rather than the virus effect itself.
Recanalization and Reconstruction of a Chronically Occluded Inferior Vena Cava Through an Existing Transjugular Intrahepatic Portosystemic Shunt in the Setting of Budd-Chiari Syndrome

Budd-Chiari syndrome (BCS) results from the occlusion or flow reduction in the hepatic veins or inferior vena cava and can be treated with transjugular intrahepatic portosystemic shunt when hepatic vein recanalization fails.1-3 Hypercoagulable patients with primary BCS are predisposed to development of new areas of thrombosis within the TIPS shunt or IVC. This case details a patient with BCS, pre-existing TIPS extending to the right atrium, and chronic retrohepatic IVC thrombosis who underwent sharp recanalization of the IVC with stenting into the TIPS stent bridging the patient until his subsequent hepatic transplantation.

Primary aortitis (PA) secondary to Listeria monocytogenes is extremely rare with only a few cases reported in the literature. Presently, there is no consensus concerning the best treatment when no complications are found in the thoracic computed tomography (CT) imaging. This report illustrates the clinical presentation and favorable clinical course of a rare case of PA secondary to Listeria monocytogenes in an 82-year-old diabetic woman, successfully treated with conservative management with 18 months of follow up. Included in this article, we additionally present a review of the literature of this uncommon etiology of infectious aortitis.

Background: The early months of the coronavirus disease 19 (COVID-19) pandemic in New York City led to a rapid transition of non-essential in-person health care, including outpatient arthroplasty visits, to a telemedicine context. Questions/Purposes: Based on our initial experiences with telemedicine in an outpatient arthroplasty setting, we sought to determine early lessons learned that may be applicable to other providers adopting or expanding telemedicine services. Methods: A cross-sectional study was performed by surveying all patients undergoing telemedicine visits with 8 arthroplasty surgeons at 1 orthopedic specialty hospital in New York City from April 8 to May 19, 2020. Descriptive statistics were used to analyze demographic data, satisfaction with the telemedicine visit, and positive and negative takeaways. Results: In all, 164 patients completed the survey. The most common reasons for the telemedicine visit were short-term (less than 6 months), postoperative appointment ( n = 88; 54%), and new patient consultation ( n = 32; 20%). A total of 84 patients (51%) noted a reduction in expenses versus standard outpatient care. Several positive themes emerged from patient feedback, including less anxiety and stress related to traveling ( n = 82; 50%), feeling more at ease in a familiar environment ( n = 54; 33%), and the ability to assess postoperative home environment ( n = 13; 8%). However, patients also expressed concerns about the difficulty addressing symptoms in the absence of an in-person examination ( n = 28; 17%), a decreased sense of interpersonal connection with the physician ( n = 20; 12%), and technical difficulties ( n = 14; 9%). Conclusions: Patients were satisfied with their telemedicine experience during the COVID-19 pandemic; however, we identified several areas amenable to improvement. Further study is warranted.
