Preparing Academics to Teach: Example of a Structured Method of Preparing Doctoral Students in Business Programs to Teach
Authors: Bonner Robert L. , Stone Christopher B. , Mittal Sarah , Phillips William , Utecht Richard L.
Published: February 2020

The qualifications of academics to teach students are often left unquestioned. Current accreditation standards, for an academic to teach, are typically determined by courses taken, certifications or degrees obtained, and/or industry experience. Doctoral programs are inconsistent in their approaches to formal instruction in pedagogy and their degree of emphasis on teaching skills assessment beyond the typical student teaching evaluations. Furthermore, in many instances, doctoral students begin teaching while they are still in their doctoral program without any formal training. We aim to address this institutionalized deficiency by providing a concise and actionable framework for teaching doctoral students how to teach that can serve as a template for other business school doctoral programs seeking to implement a doctoral teaching seminar. We provide an example of a doctoral teaching seminar in a College of Business developed to train doctoral students in five teaching competencies intended to ensure they are able to provide quality instruction to university students. In doing so, we explain the assignments and then provide evidence of the assignments’ effectiveness as well as the teaching seminar’s overall effectiveness.

Published: February 2020

Objectives: To discuss (1) recent and emerging data for pharmacological management of untreated and relapsed/refractory (R/R) mantle cell lymphoma (MCL) with agents approved in the United States, (2) important considerations for toxicity monitoring and management, and (3) preliminary data and ongoing studies for agents in MCL-specific clinical trials. Data Sources: PubMed/MEDLINE, EMBASE, Google Scholar, product labeling, National Comprehensive Cancer Network, American Cancer Society, and ClinicalTrials.gov were searched for studies published between January 1, 2017, and January 31, 2020, and key historical trials. Study Selection and Data Extraction: Relevant studies conducted in humans and selected supporting preclinical data were reviewed. Data Synthesis: MCL is a rare but usually aggressive non-Hodgkin lymphoma that most commonly affects the older population. Traditionally, the treatment of MCL has been determined based on transplant eligibility. Newer data suggest that more tolerable frontline therapy may produce outcomes similar to intensive historical induction regimens, possibly precluding fewer patients from autologous stem cell transplant and producing better long-term outcomes in transplant-ineligible patients. In the R/R setting, novel regimens are improving outcomes and changing the landscape of treatment. Relevance to Patient Care and Clinical Practice: This review summarizes and discusses recent and emerging data for management of newly diagnosed and R/R MCL; key supportive care considerations for agents are also discussed. Conclusions: Recent study results are changing management of MCL. Although these data have complicated the picture of regimen selection, increasingly effective and tolerable therapy and additional anticipated data point to a brighter future for patients with MCL.

Authors: Brown Hallie R. , Hareli Maya , Breaux Rosanna , Lugo-Candelas Claudia I. , Gair Shannon L. , Harvey Elizabeth A. , McDermott Jennifer M.
Published: February 2020

Objective: We examined behavioral and neural markers of emotion competence in young children as predictors of psychopathology, and as mediators of the relation between hyperactivity/impulsivity (H/I) and psychopathology. Method: At Time 1 (T1), children ( n = 49; ages 4–7 years) with and without H/I symptoms completed a frustration task. Frustration, observed emotion, and neural activity (P1, N2, and P3 event-related potentials) were measured. Symptoms of psychopathology were collected 18 months later (Time 2; T2). Results: T1 lability, negative affect, and frustration predicted T2 depression and aggression symptomatology, controlling for T1 symptoms. Children with difficulty allocating neural resources during and after frustration were at risk for depression, aggression, and anxiety symptoms, controlling for earlier symptoms. P3 amplitudes during recovery mediated the relation between H/I and later depression. Conclusion: Markers of emotion competence contribute to psychopathology symptoms, particularly in children at risk for attention-deficit/hyperactivity disorder (ADHD). Emotion competence skills may be useful intervention targets.
Engaged to a Robot? The Role of AI in Service
Authors: Huang Ming-Hui , Rust Roland T.
Published: February 2020

This article develops a strategic framework for using artificial intelligence (AI) to engage customers for different service benefits. This framework lays out guidelines of how to use different AIs to engage customers based on considerations of nature of service task, service offering, service strategy, and service process. AI develops from mechanical, to thinking, and to feeling. As AI advances to a higher intelligence level, more human service employees and human intelligence (HI) at the intelligence levels lower than that level should be used less. Thus, at the current level of AI development, mechanical service should be performed mostly by mechanical AI, thinking service by both thinking AI and HI, and feeling service mostly by HI. Mechanical AI should be used for standardization when service is routine and transactional, for cost leadership, and mostly at the service delivery stage. Thinking AI should be used for personalization when service is data-rich and utilitarian, for quality leadership, and mostly at the service creation stage. Feeling AI should be used for relationalization when service is relational and high touch, for relationship leadership, and mostly at the service interaction stage. We illustrate various AI applications for the three major AI benefits, providing managerial guidelines for service providers to leverage the advantages of AI as well as future research implications for service researchers to investigate AI in service from modeling, consumer, and policy perspectives.
Reliability Assessment of an Observation Tool to Measure Praise Characteristics
Authors: Markelz Andrew M. , Riden Benjamin S. , Zoder-Martell Kimberly A. , Miller Joseph E. , Bolinger Sarah J.
Published: February 2020

Supported by decades of research on praise and its effect on student behaviors, we developed the Behavior-Specific Praise–Observation Tool (BSP-OT) to measure characteristics of effective praise. We evaluated interrater reliability of the BSP-OT to measure praise specificity, contingency, and variety using intraclass correlation (ICC) and Cohen’s kappa statistics. In addition, we assessed usefulness and practicality of the tool with social validity measures. Four raters with experience in praise research completed a survey and coded videos ( n = 14) of teachers in authentic situations delivering praise. Overall assessment indicated strong reliability between raters with ICC(2, k) of .80: 95% confidence interval (CI) = [0.77, 0.83], F(269, 19906) = 5.1, p < .001, and mean kappa score of .91. Furthermore, high social validity ratings suggest the BSP-OT is a valuable contribution to the field concerning praise research and teacher development. The process of developing the BSP-OT and study findings are presented, with a discussion of implications and suggestions for future research.
ANCA-associated life-threatening systemic vasculitis after alemtuzumab treatment for multiple sclerosis
Authors: Horisberger Alice , Pantazou Vasiliki , Cuendet Géraldine , Ribi Camillo , Dunet Vincent , Théaudin Marie
Published: February 2020

Alemtuzumab is highly effective in relapsing remitting multiple sclerosis (RRMS), but autoimmune adverse events are of concern. In contrast to rare cases of immune-mediated cutaneous vasculitis, systemic vasculitis after alemtuzumab has not yet been described. We report the case of a 29-year-old man with RRMS who developed fever, auricular chondritis, cutaneous vasculitis and life-threatening diffuse alveolar haemorrhage, 12 months after alemtuzumab. Antibodies to myeloperoxidase appeared 9 months after alemtuzumab and were extremely high at the time of vasculitis. Outcome was favourable after glucocorticoids, plasma exchanges and rituximab. Thus, alemtuzumab may induce life-threatening vasculitis in patients treated for RRMS.
School-Age Bullying Victimization and Perpetration: A Meta-Analysis of Prospective Studies and Research
Authors: Walters Glenn D.
Published: February 2020

Twenty-three samples from 22 longitudinal studies assessing both bullying perpetration and bullying victimization were selected from a sample of 1,408 candidate studies using several prespecified criteria (i.e., participants ≤ 18 years of age; self-reported bullying victimization and perpetration assessed with a lag of at least 1 month but no more than 24 months; not a treatment or program study). A random effects meta-analysis was then performed on the concurrent and cross-lagged longitudinal associations between bullying victimization and perpetration in the 23 samples. A large pooled effect size ( r = .40, 95% confidence interval [CI] = [.34, .45]) was obtained for the concurrent association between bullying victimization and perpetration, whereas modest to moderate effect sizes (victimization to perpetration: r = .20, 95% CI [.17, .24]; perpetration to victimization: r = .21, 95% CI [.17, .24]) were obtained for the two cross-lagged longitudinal correlations. The results did not change when analyses were conducted separately for traditional bullying and cyberbullying outcomes. These findings indicate that bullying victimization and perpetration correlate strongly and that their cross-lagged longitudinal relationship runs in both directions, such that perpetration is just as likely to lead to future victimization as victimization is to lead to future perpetration. Different theoretical models are proposed in an effort to explain these results: cycle of violence, general strain, and social cognitive theories for victimization leading to perpetration and risky lifestyles, routine activities, and peer selection theories for perpetration leading to victimization.

Published: February 2020

Recovery-based initiatives have been found to be effective for people with addiction. Recovery’s Got Talent, a talent show designed to enhance resiliency-based attributes for people in recovery, is an innovative initiative that works toward increasing positive self-concepts and social support for people in recovery. A total of 179 Recovery’s Got Talent participants completed a survey to determine the extent to which they perceived the event instilled hope, fostered self-esteem and self-efficacy, and provided a substitute for drugs and alcohol. Positive indications were noted on the above. Recovery’s Got Talent presents an opportunity to deliver drug-free messaging of hope and support to help reduce the stigma of those living in recovery.

Pro-Environmental Views of Climate Skeptics
Authors: Haltinner Kristin , Sarathchandra Dilshani
Published: February 2020

Using data from interviews with self-identified climate change skeptics, it becomes clear that there is a public misperception about climate change skepticism. Skeptics are concerned about pollution, support environmentally friendly policies, and oppose continued reliance on oil. Current climate change communication is problematic; here, we explore the policies that garner skeptics’ support.

Description of Technique and Short-Term Outcomes of Radial Artery Access for Vascular Disease
Authors: Khalifeh Ali , Tolaymat Besher , Noggle Joseph , Kalsi Richa , Owen Christine , Nelms Justin
Published: February 2020

Objectives:

Radial artery access is widely utilized in coronary angiography with reported lower rates of vascular complications and better patient comfort. There is limited data in the literature regarding radial access in peripheral endovascular procedures. We hypothesize that radial access is safe and feasible for peripheral endovascular procedures.

Methods:

A retrospective chart review was performed for all patients who underwent angiography using radial artery access between August 2013 and December 2017. Patient demographics and perioperative data were recorded and analyzed.

Patient Selection:

The operating surgeon screened patients presenting for elective angiography for possible radial artery access. Ultrasound guidance was used in all cases. Upon cannulation, the sheath was infused with an antispasmodic cocktail, and the patients were systemically anticoagulated.

Results:

Forty-seven out of 52 patients successfully completed their procedure (90% success rate). The patients were mostly female (60%), elderly (mean age of 71 years), and had several comorbidities. Preoperative diagnoses were variable. Procedures were both diagnostic (58%) and interventional (42%) with maximum sheath size used being 7F and median fluoroscopy time of 7.5 minutes. Only 2 patients experienced perioperative complications, and both of these were minor hematomas that resolved with manual pressure.

Conclusions:

Transradial arterial access for peripheral vascular angiography and interventions is safe and feasible. With low complication rates and increased patient comfort, transradial access serves as an excellent alternative to transfemoral access for a variety of endovascular procedures.
Association of Operative Repair Type and Trauma Center Designation With Outcomes in Ruptured Abdominal Aortic Aneurysm Repair
Authors: Wessels Lyndsey E. , Calvo Richard Y. , Sise Michael J. , Bowie Jason M. , Butler William J. , Bansal Vishal , Sise C. Beth
Published: February 2020

Objective:

Open repair of ruptured abdominal aortic aneurysm (rAAA) has shown improved outcomes at trauma centers. Whether the benefit of trauma center designation extends to endovascular repair of rAAA is unknown.

Methods:

Retrospective cohort study using the California Office of Statewide Health Planning and Development 2007 to 2014 discharge database to identify patients with rAAA. Data included demographic and admission factors, discharge disposition, International Classification of Diseases, Ninth Revision, Clinical Modification codes, and hospital characteristics. Hospitals were categorized by trauma center designation and teaching hospital status. The effect of repair type and trauma center designation (level I, level II, or other—other trauma centers and nondesignated hospitals) was evaluated to determine rates and risks of 9 postoperative complications, in-hospital mortality, and 30-day postdischarge mortality.

Results:

Of 1941 rAAA repair patients, 61.2% had open and 37.8% had endovascular; 1.0% had both. Endovascular repair increased over the study interval. Hospitals were 12.0% level I, 25.0% level II, and 63.0% other. A total of 48.7% of hospitals were teaching hospitals (level I, 100%; level II, 42.2%; and other, 41.8%). Endovascular repair was significantly more common at teaching hospitals (41.5% vs 34.3%, P < .001) and was the primary repair method at level I trauma centers ( P < .001). Compared with open repair, endovascular repair was protective for most complications and in-hospital mortality. The risk for in-hospital mortality was highest among endovascular patients at level II trauma centers (hazard ratio 1.67, 95% confidence interval [CI]: 0.95-2.92) and other hospitals (hazard ratio 1.66, 95% CI: 1.01-2.72).

Conclusions:

Endovascular repair overall was associated with a lower risk of adverse outcomes. Endovascular repair at level I trauma centers had a lower risk of in-hospital mortality which may be a result of their teaching hospital status, organizational structure, and other factors. The weight of the contributions of such factors warrants further study.
Multispectral imaging technology: Visualize, analyze, phenotyping, and quantify immune cells in situ
Authors: Pivetta Eliana , Spessotto Paola
Published: February 2020

In the personalized medicine era, the field of immunohistopathology is evolving to provide even more precise diagnostic information to efficiently apply targeting therapies. In this regard, MultiSpectral fluorescence Imaging (MSI) is a powerful and reliable technique that provides a detailed and remarkable analysis of multiple biomarkers within their histological context. In particular, the analysis of the immune infiltrate in conjunction with the expression of immune checkpoint molecules could explain why the efficacy of the promising treatments based on immune modulator monoclonal antibodies is still limited. We analyzed the advantages and the pitfalls of applying MSI technology to investigate the immune infiltrate in correlation with programmed death-ligand 1 expression in paraffin embedded ovarian cancer samples.
Molecular imaging and immunotherapy
Authors: Evangelista Laura
Published: February 2020

The utility of positron emission tomography (PET) for the evaluation of response to immunotherapy has been considered a hot topic, particularly in the last 2 to 3 years. Different experiences have been collected in clinical practice, with 18F-Fluorodeoxyglucose (FDG) PET/computed tomography (CT), particularly in patients affected by lymphoma, malignant melanoma, and lung cancer. It has been tested in different settings of disease, from the prediction to the prognosis relative to the response to immunotherapy. In the present mini-review, some evidence is reported about the role of FDG PET/CT in patient candidates to or treated with immunotherapy.
State of the art and trends of circulating cancer biomarkers
Authors: Gion Massimo , Trevisiol Chiara , Fabricio Aline S.C.
Published: February 2020

The role of biomarkers is crucial in oncology for both early diagnosis and the personalization of cancer treatments. Tissue biomarkers have gained a central role as predictors of the response to an increasing number of anticancer agents; conversely, the clinical role of circulating biomarkers (c-TMs) is limited and has remained almost unchanged over the years. The position of guidelines is summarized and discussed with reference to the potential usefulness of c-TMs in those areas of application that cannot be covered by tissue biomarkers. The pipeline of translational research on biomarkers is briefly described; the differences among analytical validation, clinical validation, and clinical utility are discussed, emphasizing that the assessment of clinical utility is the ultimate step toward clinical use. The role of monitoring of appropriateness as a proxy indicator of how the research pipeline has actually worked is discussed, and data and c-TMs overordering rates are reported. The role and limits of guidelines to influence appropriate c-TMs ordering are discussed. The design of primary studies on c-TMs is examined, underlining that they mainly focus on clinical validation rather than on clinical utility. The role of regulatory boards is also briefly presented and discussed.
Inflammation and infiltration: can the radiologist draw a line? MRI versus CT to accurately assess medullary involvement in parosteal osteosarcoma

Published: February 2020

Cancer causes inflammation as it progresses through healthy tissue. The differentiation of tumoral growth from the surrounding inflammatory change is paramount in planning surgeries seeking to preserve function. This retrospective study aims at illustrating how a careful use of imaging (computed tomography (CT)/magnetic resonance imaging (MRI)) can help to draw the line between infiltration and inflammation. Out of 72 cases of parosteal osteosarcoma in our institution we selected 22 which had pretreatment imaging, and out of those, 14 that had both MRI and CT. Using Fisher’s exact test, we evaluated the performance of each technique on accurately diagnosing medullary tumor infiltration, using histological analysis as a gold standard. All cases (14/14) demonstrated medullary abnormality on MRI, but only 6/14 (42.9%) demonstrated abnormality on CT. The 8/14 cases with MRI abnormality but no CT abnormality (57.1%) showed inflammation with no tumoral cells present on histological analysis. In the cases where the two examinations showed medullary abnormality (6/14) histology demonstrated tumoral infiltration. MRI demonstrated high sensitivity and negative predictive value, but low specificity and low positive predictive value and accuracy (P=1). CT demonstrated high sensitivity, specificity, high positive and negative predictive values and accuracy (P = 0.000333). MRI is highly sensitive for the detection of medullary abnormality but lacks specificity for tumor invasion. Correlation with CT is recommended in all cases of positive MR to add specificity for tumors. The adequate use of the two imaging methods allows to differentiate between inflammatory change and tumoral infiltration in POS, relevant for surgical planning.

Published: February 2020

Many applications in robotics require precise tracking of the prescribed path. The aim of this article is to develop and verify by computer simulation a control design method which ensures that the “output” of the robot will move along a prescribed path. A virtual vehicle approach algorithm was used to track a predefined vehicle path. The idea behind this algorithm is that the movement of a virtual vehicle on a predefined path is controlled by a differential equation whose input is a control deviation representing the distance between a real and a virtual vehicle. The main advantage of the path-following approach is that, based on this approach, the feedback realized is invariant to the path.
School principals at different stages of adult ego development: Their sense-making capabilities and how others experience them
Authors: Gilbride Neil , James Chris , Carr Sam
Published: February 2020

The way school principals make sense of the context of their work shapes their actions. As in all adults, principals’ sense-making capability is a function of the ego and can change over time. Adult ego development theory describes distinct, qualitatively different stages of sense-making ability. The research reported here assessed the adult ego development stage of 20 school principals in England using the Washington University Sentence Completion Test. Principals in the Self-Aware, Conscientious and Individualist stages of adult ego development were identified. The research used a critical incident technique to analyse principals’ sense-making capabilities and how others experience them in their role as principals. The findings show substantive differences between those in different stages of adult ego development in relation to their sense-making processes, the feelings they experience and display as emotions, how they involve others in the sense-making process and how others experience them. There is a discernible trend in the behaviours of school principals and how others experience them that relates to the transition from the Self-Aware stage to the Conscientious stage and then to the Individualist stage. These findings have significant implications for understanding the practice of school principals.
Improving Hashimoto’s thyroiditis by eradicating Blastocystis hominis: Relation to IL-17
Authors: El-Zawawy Hanaa Tarek , Farag Huda Fahmy , Tolba Mona Mohamed , Abdalsamea Hanaa Abdalbasit
Published: February 2020

Background:

Hashimoto’s thyroiditis (HT) is a common autoimmune disorder that causes significant morbidity. Interleukin (IL)-17 was identified as a major contributing factor in the pathogenesis of HT. Blastocystis hominis (BH) is a very common infection and has been shown to be associated with several diseases. Our aim was to determine serum IL-17 level in HT patients with and without BH infection and the effect of eradicating BH in patients with HT.

Methods:

A prospective cohort study was conducted on 20 HT patients not infected with BH (group I), 20 HT patients infected with BH (group II), and 20 healthy patients (group III). Serum free triiodothyronine (FT3), free thyroxine (FT4), thyroid stimulating hormone (TSH), thyroid peroxidase antibodies (anti-TPO), and IL-17 were performed by ELISA method and were repeated in group II after 6 weeks of eradication of BH.

Results:

Patients with HT showed a significantly higher serum IL-17 compared with controls. IL-17 was significantly higher in HT patients infected with BH compared with HT patients not BH infected (mean 6.93 ± 2.83 pg/ml versus 3.25 ± 1.55 pg/ml, p = 0.003). After BH eradication TSH, anti-TPO, and IL-17 were significantly decreased (mean 14.76 ± 11.11 µIU/ml versus 9.39 ± 7.11 µIU/ml, p < 0.001; mean 308 ± 175.6 IU/ml versus 295.4 ± 167.1 IU/ml, p = 0.006; and mean 6.93 ± 2.83 pg/ml versus 6.45 ± 2.48 pg/ml, p < 0.001), respectively. Multivariate analysis after treating BH infection showed that IL-17 was significantly negatively correlated with FT3 (adjusted p = 0.002) and significantly positively correlated with anti-TPO (adjusted p = 0.045).

Conclusion:

Treatment of BH infection ameliorates HT through reduction in IL-17, anti-TPO, and TSH.

Removal of a separated endodontic instrument by using the modified hollow tube–based extractor system: A case report
Authors: AlRahabi Mothanna K , Ghabbani Hani M
Published: February 2020

The frequency of separation of NiTi rotary instruments has increased with the increasing use of these instruments, and this error may result from inadequate experience of using these instruments. This iatrogenic error can complicate root canal treatment, and special experience is required to manage this problem. This case report describes the management of the separation of an F3 instrument from a ProTaper NiTi rotary system. A 30-year-old man was referred to the College of Dentistry, Taibah University (Saudi Arabia) with an intracanal separated NiTi rotary instrument (F3 of the ProTaper system; Dentsply Maillefer, Ballaigues, Switzerland) in the canal of the maxillary right canine. The separated instrument was removed by using the modified hollow tube–based extractor system. The present case revealed that sometimes a simple method can be an effective alternative of a professional method; using NiTi rotary instruments with strict adherence is important for the prevention of instrument separation.
The practice of preparation for complex negotiations
Authors: Lindholst Morten , Bülow Anne Marie , Fells Ray
Published: February 2020

Negotiators are routinely exhorted to prepare well, but what do they do in practice? This article draws on data collected as a team of negotiators prepared their strategy during the lengthy negotiations over a major power generation infrastructure contract. Using a framework that we developed using terms from the literature, the team’s preparation meetings were observed and then analysed for content, timing and changes in participation.

It is shown that the standard checklist notion of preparation needs to be reconsidered as a multilevel, dynamic concept that changes in character over time. Far from just a first stage, the team’s continued preparation occurred in feedback meetings after rounds of negotiation at the table, between negotiation sessions and immediately before the next round of negotiations, and progress was seen to hinge on the differentiation of the preparation. Consequently, this long-term study provides insight into a key element of any general theory of negotiation while also suggesting implications for practitioners working with negotiating teams.
Fluids on Pictures on Screens: Pseudonymous Affect on Reddit’s TributeMe
Authors: van der Nagel Emily
Published: February 2020

Tributing is the practice of sending a sexually explicit photo adorned in ejaculate to the subject of the photo. It involves an entanglement of screens, online identities, platforms, affect, materiality, and bodily fluids and plays out in a particular way on bulletin board Reddit. This article draws on two week-long archives of the subreddit TributeMe to study the way affective exchanges are intensified by the circulation of digital images. I draw on the way affect pertains to movement to argue that tributes express affect moving in two ways: through the body, with the ejaculation evidencing arousal and standing in for a physical encounter, and through social media platforms, with images being circulated as digital objects. Although the strict verification system involves providing consent for the image to be tributed, people deliberately remain pseudonymous on TributeMe. This is a strategy to compartmentalize their involvement in TributeMe so it does not appear as a publicly accessible digital trace. The pseudonymity of TributeMe allows people to engage in sexualized affective exchanges in public.
Exploring Import-led Growth in India: Evidence from the Post-reform Period
Authors: Maitra Biswajit
Published: February 2020

While the export-led growth (ELG) hypothesis attracted much attention historically, the import-led growth (ILG) dimension received little attention despite important linkages. The present article studies whether the ELG, ILG, growth-led export (GLE) and growth-led import (GLI) propositions hold in India for the post-reform period. Accordingly, the short-run and the long-run impacts of exports, imports, exchange rate and trade openness on income are assessed. The analysis finds prominent evidence of ILG hypothesis, both in the short run and in the long run suggesting that import is a significant bearing of economic growth, while the ELG hypothesis holds only in the short run. Besides, the exchange rate and trade openness have negative impacts on income. The study also finds indications of significant, stable export- and import-demand functions, where income and trade openness have caused exports and imports to rise. As income causes a rise in both export and import, the GLE and GLI hypotheses are also testified. The exchange rate depreciation and lagged imports also cause the export to a raise. As trade particularly import is an essential factor in income growth, the country should encourage more outer-orientation of the economy. An import liberalization policy could be useful for economic growth.

Atelocollagen Injection Improves Tendon Integrity in Partial-Thickness Rotator Cuff Tears: A Prospective Comparative Study
Authors: Kim Jong-Ho , Kim Dong-Jin , Lee Hyo-Jin , Kim Baek-Kyu , Kim Yang-Soo
Published: February 2020

Background:

Ongoing controversy surrounds the best treatment modality for partial-thickness rotator cuff tears.

Purpose:

To investigate the effects of atelocollagen injection in patients with small, symptomatic, intratendinous rotator cuff tears.

Study Design:

Randomized controlled trial; Level of evidence, 1.

Methods:

From January 2014 to December 2017, 94 patients who had small, symptomatic, intratendinous rotator cuff tears were enrolled and randomly allocated to 1 of 3 groups: intratendinous injection with 0.5 mL of type I atelocollagen (group 1, n = 32), intratendinous injection with 1 mL of type I atelocollagen (group 2, n = 30), and no injection of type I atelocollagen (group 3, n = 32). American Shoulder and Elbow Surgeons score, Constant Shoulder Score, visual analog scale pain score, and range of motion were evaluated before injection; at 3, 6, and 12 months after injection; and at final follow-up. Magnetic resonance imaging (MRI) was performed at least 6 months after injection to evaluate rotator cuff integrity.

Results:

Demographic data did not differ significantly among the 3 groups before injection ( P > .05). The mean follow-up period was 24.7 months. The functional and pain scores in groups 1 and 2 were significantly improved at final follow-up ( P < .05). No significant improvement was seen in functional or pain scores at final follow-up in group 3 ( P > .05). Groups 1 and 2 had significantly better functional scores compared with group 3 at final follow-up ( P < .05). The proportion of patients with a decrease in size of the torn tendon on follow-up MRI at least 6 months after atelocollagen injection was significantly higher in group 1 (28.1%; P = .02) and group 2 (36.7%; P = .003) compared with group 3 (6.3%).

Conclusion:

Atelocollagen injection can improve the functional outcome and integrity of the tendon in intratendinous rotator cuff tears.
An empirical analysis of research paradigms within international human resource management: The need for more diversity
Authors: Kornau Angela , Frerichs Ilka Marie , Sieben Barbara
Published: February 2020

The goal of this article is to provide a fine-grained analysis of international human resource management research that addresses the different perspectives applied in that research. We coded 203 peer-reviewed international human resource management articles published between 2011 and 2018 with content analytical methods guided by the compass of management research developed by Sieben, which is rooted in critical management research. We were particularly attentive to the various discursive orientations international human resource management scholars have adopted, including ideologically critical, poststructuralist, functionalist and interpretive perspectives. We further examined which methods, theoretical perspectives and topics were common within and across different perspectives. This analysis indicated that critical research intending to politicize and question existing structures and ways of organizing is still marginal. Along with the dominance of functionalist and interpretive studies, papers in our dataset commonly use a strategic human resource perspective, are predominantly interested in the human resource management–performance link and focus rather narrowly on multinational corporations and expatriates. Furthermore, while international human resource management scholars increasingly account for the contextual embeddedness of organizations through macro-level theories, they mainly apply institutional perspectives that view organizations as adapting to institutional constraints. We propose a more diverse and reflexive approach – inspired by ideologically critical and poststructuralist perspectives – that may help to overcome these blind spots. Such an approach might, for instance, look at types of organizations other than multinational corporations and individuals other than highly skilled expatriates and might explicitly bring multiple, external stakeholders into the picture. We conclude by suggesting that international human resource management research and practice would benefit from more research diversity which enables more holistic analyses of phenomena, more innovative research and resultant insights, and more space for meta-theoretical reflections.
Beneficial bacteria activate nutrients and promote wheat growth under conditions of reduced fertilizer application

Published: February 2020

Background

Excessive application of chemical fertilizer has exerted a great threat to soil quality and the environment. The inoculation of plants with plant-growth-promoting rhizobacteria (PGPR) has emerged as a great prospect for ecosystem recovery. The aim of this work to isolate PGPRs and highlights the effect of bacterial inoculants on available N/P/K content in soil and on the growth of wheat under conditions of reduced fertilizer application.

Results

Thirty-nine PGPRs were isolated and tested for their growth-promoting potential. Thirteen isolates had nitrogen fixation ability, of which N9 (Azotobacter chroococcum) had the highest acetylene reduction activity of 156.26 nmol/gh. Eleven isolates had efficient phosphate solubilizing ability, of which P5 (Klebsiella variicola) released the most available phosphorus in liquid medium (231.68 mg/L). Fifteen isolates had efficient potassium solubilizing ability, of which K13 (Rhizobium larrymoorei) released the most available potassium in liquid medium (224.66 mg/L). In culture medium supplemented with tryptophan, P9 (Klebsiella pneumoniae) produced the greatest amount of IAA. Inoculation with the bacterial combination K14 + 176 + P9 + N8 + P5 increased the alkali-hydrolysed nitrogen, available phosphorus and available potassium in the soil by 49.46, 99.51 and 19.38%, respectively, and enhanced the N, P, and K content of wheat by 97.7, 96.4 and 42.1%, respectively. Moreover, reducing fertilizer application by 25% did not decrease the available nitrogen, phosphorus, and potassium in the soil and N/P/K content, plant height, and dry weight of wheat.

Conclusions

The bacterial combination K14 + 176 + P9 + N8 + P5 is superior candidates for biofertilizers that may reduce chemical fertilizer application without influencing the normal growth of wheat.

Background

Timely access in primary health care is one of the key issues facing health systems. Among many interventions developed around the world, advanced access is the most highly recommended intervention designed specifically to improve timely access in primary care settings. Based on greater accessibility linked with patients’ relational continuity and informational continuity with a primary care professional or team, this organizational model aims to ensure that patients obtain access to healthcare services at a time and date convenient for them when needed regardless of urgency of demand. Its implementation requires a major organizational change based on reorganizing the practices of all the administrative staff and health professionals. In recent years, advanced access has largely been implemented in primary care organizations. However, despite its wide dissemination, we observe considerable variation in the implementation of the five guiding principles of this model across organizations, as well as among professionals working within the same organization.

The main objective of this study is to assess the variation in the implementation of the five guiding principles of advanced access in teaching primary healthcare clinics across Quebec and to better understand the influence of the contextual factors on this variation and on outcomes.

Methods

This study will be based on an explanatory sequential design that includes 1) a quantitative survey conducted in 47 teaching primary healthcare clinics, and 2) a multiple case study using mixed data, contrasted cases (n = 4), representing various implementation profiles and geographical contexts. For each case, semi-structured interviews and focus group will be conducted with professionals and patients. Impact analyses will also be conducted in the four selected clinics using data retrieved from the electronic medical records.

Discussion

This study is important in social and political context marked by accessibility issues to primary care services. This research is highly relevant in a context of massive media coverage on timely access to primary healthcare and a large-scale implementation of advanced access across Quebec. This study will likely generate useful lessons and support evidence-based practices to refine and adapt the advanced access model to ensure successful implementation in various clinical contexts facing different challenges.

Published: February 2020

Background

Fever is a cause for concern for both parents and the treating pediatrician and a common reason for antibiotic overuse. However, the proportion of children hospitalized for fever with serious bacterial infection (SBI) is uncertain. We aimed to evaluate the epidemiological, clinical, hematological, and biochemical risks for SBI among the children admitted with fever.

Method

This prospective study was conducted in a rural teaching hospital in India on consecutive children, aged 3 months–12 years, presenting with fever 100 °F (37.7 °C) or higher. The presence of SBI was confirmed with one of the following criteria: (a) a positive blood culture; (b) roentgenographically confirmed pneumonia with high titres of C-reactive protein; (c) a culture-confirmed urinary tract infection; (d) enteric fever diagnosed clinically in addition to either a positive blood culture or high Widal titers; and (e) meningitis diagnosed clinically in addition to either a positive blood culture or cerebrospinal fluid culture. A predefined questionnaire was filled.

Results

A total of 302 children were included in the study, out of which 47% (95% CI 41.4–52.7%) presented with SBI. The factors associated with confirmed SBI in bivariate analysis were history of previous hospitalization, history of chronic illness, history of medication in the previous 1 week, a partially immunized child, history of common cold, moderate-grade fever, toxic look, significant lymphadenopathy, absence of BCG scar, delayed development, irritability, breathlessness, respiratory distress, poor feeding, significant weight loss, suspected urinary tract infection, hyponatremia, hypokalemia, and abnormal leucocyte count. The final generalized logistic regression model revealed partially immunized child (RR 4.26), breathlessness (RR 1.80), weight loss (RR 2.28), and suspected urinary tract infection (RR 1.95) as risk factors for the increased risk of SBI.

Conclusion

The study identified multiple risk factors for SBI. Pediatricians can be made aware of these risk factors. Further studies are warranted to identify age-specific risk factors for SBI because most clinicians depend on clinical signs and symptoms to identify SBI.

Background

Despite research suggesting an association between certain herb use during pregnancy and delivery and postnatal complications, herbs are still commonly used among pregnant women in sub-Sahara Africa (SSA). This study examines the factors and characteristics of women using local herbs during pregnancy and/or labor, and the associations between local herb use and postnatal complications in Kigoma, Tanzania.

Methods

We analyzed data from the 2016 Kigoma Tanzania Reproductive Health Survey (RHS), a regionally representative, population-based survey of reproductive age women (15–49 years). We included information on each woman’s most recent pregnancy resulting in a live birth during January 2014–September 2016. We calculated weighted prevalence estimates and used multivariable logistic regression to calculate adjusted odds ratios (aOR) and 95% confidence intervals (CI) for factors associated with use of local herbs during pregnancy and/or labor, as well as factors associated with postnatal complications.

Results

Of 3530 women, 10.9% (CI: 9.0–13.1) used local herbs during their last pregnancy and/or labor resulting in live birth. The most common reasons for taking local herbs included stomach pain (42.9%) and for the health of the child (25.5%). Adjusted odds of local herb use was higher for women reporting a home versus facility-based delivery (aOR: 1.6, CI: 1.1–2.2), having one versus three or more prior live births (aOR: 1.8, CI: 1.4–2.4), and having a household income in the lowest versus the highest wealth tercile (aOR: 1.4, CI: 1.1–1.9). Adjusted odds of postnatal complications were higher among women who used local herbs versus those who did not (aOR: 1.5, CI: 1.2–1.9), had four or more antenatal care visits versus fewer (aOR: 1.4, CI: 1.2–1.2), and were aged 25–34 (aOR: 1.1, CI: 1.0–1.3) and 35–49 (aOR: 1.3, CI: 1.0–1.6) versus < 25 years.

Conclusions

About one in ten women in Kigoma used local herbs during their most recent pregnancy and/or labor and had a high risk of postnatal complications. Health providers may consider screening pregnant women for herb use during antenatal and delivery care as well as provide information about any known risks of complications from herb use.
Integrative analysis of breast cancer profiles in TCGA by TNBC subgrouping reveals novel microRNA-specific clusters, including miR-17-92a, distinguishing basal-like 1 and basal-like 2 TNBC subtypes

Published: February 2020

Background

The term triple-negative breast cancer (TNBC) is used to describe breast cancers without expression of estrogen receptor, progesterone receptor or HER2 amplification. To advance targeted treatment options for TNBC, it is critical that the subtypes within this classification be described in regard to their characteristic biology and gene expression. The Cancer Genome Atlas (TCGA) dataset provides not only clinical and mRNA expression data but also expression data for microRNAs.

Results

In this study, we applied the Lehmann classifier to TCGA-derived TNBC cases which also contained microRNA expression data and derived subtype-specific microRNA expression patterns. Subsequent analyses integrated known and predicted microRNA-mRNA regulatory nodes as well as patient survival data to identify key networks. Notably, basal-like 1 (BL1) TNBCs were distinguished from basal-like 2 TNBCs through up-regulation of members of the miR-17-92 cluster of microRNAs and suppression of several known miR-17-92 targets including inositol polyphosphate 4-phosphatase type II, INPP4B.

Conclusions

These data demonstrate TNBC subtype-specific microRNA and target mRNA expression which may be applied to future biomarker and therapeutic development studies.
