A description of the tadpole of Megophrys "Brachytarsophrys" intermedia (Smith, 1921)
Authors: TAPLEY BENJAMIN , NGUYEN LUAN THANH , VAN LE MANH
Published: September 2020

Megophrys Kuhl and Van Hasselt are an Asian radiation of terrestrial frogs which are usually associated with montane forest (Mahony et al. 2017). The Annam horned frog (Megophrys intermedia) is reported from montane evergreen forest in Vietnam and Lao People’s Democratic Republic (Stuart 2005; Hendrix et al. 2008; Nguyen et al. 2009; Tran 2013; Orlov et al. 2015; IUCN 2017; Mahony et al. 2017). The IUCN Red List assessment for the species reports an elevational range of 782–1500 m asl (IUCN 2017) although the type locality was reported to be above 1500 m asl (Smith 1921), and Tran (2013) collected a specimen at 1515 m asl. Megophrys intermedia is assessed as Least Concern (IUCN 2017) and little is known about the reproductive behaviour and life history of the species. In Lam Dong Province (Vietnam), male M. intermedia call in March (Tran 2013); on the Langbian Plateau (Vietnam), male specimens are reported to call by day and by night from March to May and specimens called from within deep crevices between boulders in streams (Smith 1921); in Xe Kong Province (Laos), males call or guard egg clutches that are laid in water in July (Stuart 2005).

Published: September 2020

Frogs in the genus Megophrys are an Asian radiation of stream-breeding frogs. The tadpoles of many Megophrys species are undescribed; those that are described are often dubiously allocated to species by association with post metamorphic specimens at collection sites and without supportive molecular data. We provide detailed descriptions of the larvae of five species of Megophrys from the Hoang Lien Range in northwest Vietnam: Megophrys fansipanensis, M. gigantica, M. hoanglienensis, M. jingdongensis and M. maosonensis. Tadpoles from different subgenera differ from each other via a combination of patternation in life, oral disc shape and tail morphology but given the small sample size, and limited number of species it is unlikely that these differences can be applied more widely to delineate subgenera. Morphological differences between tadpoles from species within the subgenus Panophrys were insufficient to clearly delineate all species. The ability to identify tadpoles is likely to advance our understanding of the frog fauna in mainland southeast Asia.
Description of a new species of deep-water king-crab (Crustacea: Decapoda: Anomura) from the southeastern Arabian Sea
Authors: PADATE VINAY P. , CUBELIO SHERINE SONIA , TAKEDA MASATSUNE
Published: September 2020

A new species of the deep-water king-crab genus Neolithodes A. Milne-Edwards & Bouvier, 1894 (Anomura: Lithodidae) is described herein from the southeastern Arabian Sea (1064–1338 m depth). Neolithodes indicus sp. nov. shows morphological proximity with three congeneric species, N. brodiei Dawson & Yaldwyn, 1970, N. flindersi Ahyong, 2010a and N. nipponensis Sakai, 1971 in bearing less numerous secondary spines on the carapace, the dactylus of the chelipeds with a convex dorsal margin and dorsoventrally compressed meri of the pereopods 2–4. The new species can be easily distinguished from these congeners in possessing the less densely spinulose carapace and appendages, short rostrum, simple antennal scaphocerite, the absence of large spines on the flexor margins of the pereopods 2–3 meri, and a stouter pereopod 4 propodus.
A Unified Approach for Heart Rate Estimation from Electrocardiogram and Arterial Blood Pressure Pulses
Authors: Singh Omkar , Sunkaria Ramesh Kumar
Published: September 2020

The objective of this manuscript is to propose a unique methodology for heart rate estimation derived from Electrocardiogram (ECG) or arterial blood pressure (abp) signal. This methodology relies on the identification of a signal's fundamental frequency by use of empirical wavelet analysis,
followed by peak identification within windows based on pseudo-periodic assumption. The proposed methodology is based on the concept that the most of the cardiovascular signals are quasi-periodic in nature. The proposed technique estimates the fundamental frequency of the signal from its corresponding
Fourier spectrum using empirical wavelet transform and then utilizes a search window for locating the peaks in the corresponding signal which identifies the R peaks in ECG or Systolic peaks in blood pressure pulses. This approach was validated on 100 recordings of the computing in cardiology
challenge 2014 training data set and performance parameters were compared with methods running only on ECG or ABP signals independently.
Mono Dispersable Water-Soluble Iron Sulfide Nanoclusters: Synthesis, Characterization and Catalytic Application for Highly Efficient Synthesis of Xanthene Derivatives
Authors: Yadav Kumar Karitkey , Kumar Hemant , Pani Balaram , Roy Indrajit , Kumar Pramod
Published: September 2020

In this manuscript, we have synthesized Iron sulfide nanoclusters (FeSNCs) by precipitation reaction between ferric chloride (FeCl3 · 6H2O) and thiourea with sodium borohydride (NaBH4) as a reducing agent at room temperature in water. These nanoclusters
are synthesized within two minutes. The morphology and size of these synthesized FeSNCs were confirmed from transmission electron microscopy (TEM) and scanning electron microscopy (SEM). TEM and SEM data showed that the average diameters of these FeSNCs are around 70 nm. The Power X-ray diffraction
(XRD) patten of the FeSNCs clearly showed the crystalline nature of these nanoclusters. Vibrating sample magnetometer (VSM) experiment showed that these nanoclusters are ferromagnetic in nature having high magnetization (20 emu/g). The nitrogen adsorption isotherm of FeSNCs confirmed the porous
nature. These well characterized FeSNCs were further utilized as a catalyst for the synthesis of 9-aryl-1,8-dioxooctahydroxanthenes and 14-substituted-14H-dibenzo[a, j] xanthene derivatives. It is observed that the catalytic activities of FeSNCs are much better than the other
reported heterogeneous and homogeneous catalysts. After completion of the reaction, FeSNCs are separated from the reaction mixture with the help bar magnet, washed and reused for the next catalytic reaction. Current method offers several advantages over other reported methods such as excellent
yields, short reaction times, simple reaction procedure, and reusability of the catalyst upto five times without any significant loss in its activity.
Throughflow and Gravity Modulation Effects on Double Diffusive Oscillatory Convection in a Viscoelastic Fluid Saturated Porous Medium
Authors: Manjula S. H. , Kiran Palle
Published: September 2020

Weakly nonlinear stability analysis has been performed using the finite amplitude Ginzburg-Landau model. The layer is oscillating vertically in sinusoidal manner. Using the finite amplitude analysis heat mass/transfer is quantified in the system. The disturbances of the flow are expanded
in power series of small parameter. In addition to the modulation, the effect of throughflow is discussed on heat/mass transfer in the system. The values of viscoelastic parameters are considered in this paper are λ1 > λ2 and Γ < 1 to validate
the problem. The time relaxation parameter λ1 has destabilizing effect, while the time retardation parameter λ2 has stabilizing effect on the system. The effects of amplitude and frequency of modulation on heat/mass transports have been analyzed and depicted
graphically. The studies establish that the heat/mass transports can be controlled effectively by g-jitter and throughflow. Further, it is found that better results may obtain for an oscillatory mode of convection.

Authors: Sharma Sonika , Sharma Neeraj
Published: September 2020

The tris(nicotinohydroxamato) vanadium(III) complex of composition [V(C5H4NCONHO)3] have been synthesized by the reaction of VCl3 with three equivalents of potassium salts of nicotinohydroxamate in methanol medium under nitrogen atmosphere.
The characterization of complex has been accomplished by elemental analyses, molar conductivity, magnetic moment measurements, IR, electronic and mass spectral studies. An octahedral geometry around vanadium, inferred from physicochemical and spectral studies has been proposed for complex.
The antimicrobial activities of the newly synthesized complex, ligand and precursor VCl3 have been evaluated against some pathogenic bacteria as E.coli, S.aureus, S.typhi, S. paratyphi, S.epidermidis and K.pneumoniae and fungi such as A.niger, B.fulva and M.circinelloid
by minimum inhibitory concentration method. The complex exhibited promising antimicrobial activity relative to free ligand and metal precursor.

Development of quasi-unidirectional fabrics with hemp fiber: A competitive reinforcement for composite materials
Authors: Corbin Anne-Clémence , Sala Benjamin , Soulat Damien , Ferreira Manuela , Labanieh Ahmad-Rashed , Placet Vincent
Published: September 2020

This study focuses on the development and mechanical testing of a quasi-unidirectional woven hemp fabric for composite applications. The fabric is designed to combine the advantages of easy handling, impregnability by resin and fiber alignment. In this sense, low twisted rovings, low crimping characteristics and a high roving density in the main direction were used. The results show that the manufacturing process proposed for this highly unbalanced woven fabric is less aggressive than that for a balanced pattern, and the effective tensile properties of the fibers are preserved. This innovative hemp fabric is also used to manufacture unidirectional and cross-ply laminated composites. The results indicate competitive properties relative to those of commercial flax-based reinforcements with rigidities similar to those of composites made with quasi-unidirectional woven fabrics, non-crimp fabrics and tapes.
Relational Dependence in a Culture of Self-Creation: A Theological Query into the Health of the Medical World
Authors: Nepil John
Published: September 2020

Half of the medical professionals in the United States are experiencing symptoms of burnout. From the perspective of theological anthropology, this dehumanizing aspect of the field is not reducible to ethical failures, for it is rooted in the radically new worldview known as self-creation. As an implicit denial of Christian understanding of creation, self-creation entails a rejection of relationality and dependence—both proper to the Revelation of Jesus Christ. This article proposes that this lost Christian patrimony is intimately connected to the increasingly unhealthy dependence we place upon modern medicine. Relying on theologian Joseph Ratzinger, we will come to see that a recovery of relational dependence is not only necessary for the salvation of man—but the very health of the medical world at large.
Sorting Schools: A Computational Analysis of Charter School Identities and Stratification
Authors: Haber Jaren R.
Published: September 2020

Research shows charter schools are more segregated by race and class than are traditional public schools. I investigate an underexamined mechanism for this segregation: Charter schools project identities corresponding to parents’ race- and class-specific parenting styles and educational values. I use computational text analysis to detect the emphasis on inquiry-based learning in the websites of all charter schools operating in 2015–16. I then estimate mixed linear regression models to test the relationships between ideological emphasis and school- and district-level poverty and ethnicity. I thereby transcend methodological problems in scholarship on charter school identities by collecting contemporary, populationwide data and by blending text analysis with hypothesis testing. Findings suggest charter school identities are both race and class specific, outlining a new mechanism by which school choice may consolidate parents by race and class—and paving the way for behavioral and longitudinal studies. This project contributes to literatures on school choice and educational stratification.
Experimental research on desorption characteristics of gas-bearing coal subjected to mechanical vibration
Authors: Chen Xuexi , Zhang Liang , Shen Maoliang
Published: September 2020

Mechanical vibration can induce coal and gas outburst accidents, and can also promote the exploitation of coalbed methane. In this paper, a vibration-adsorption-desorption experiment system was established, the effects of coal sample particle diameter, gas pressure, and vibration frequency on gas desorption were studied. Mechanical vibration can generate a shear force in the adsorbed gas and promote gas desorption, but there are appropriate vibration parameters. Within the range of experimental parameters, the larger the amplitude, the more favorable for gas desorption. The change rules of gas desorption rate and desorption quantity under different conditions are basically the same, showing a power function shape with time increase, and most of the desorption quantity was completed within the first 5 minutes. The gas desorption rate and desorption quantity were positively related to the gas adsorption pressure. The results have great reference value for preventing gas outbursts and promoting gas exploitation.
Set Trippin’: An Intersectional Examination of Gang Members
Authors: Marzo Lea
Published: September 2020

Research on gang membership often ignores critical intersections of gender, class, and race. I seek to bridge the gap between the raced and gendered experiences of Black gang members, especially women whose experiences are often overlooked. Utilizing critical race theory, I will examine how gender performances are influenced by gang membership and how members and their associates construct their identities. An intersectional focus on Black women gang membership will broaden our understanding of gang literature where Black men are often overrepresented. This research will produce participant-led data that unearth gang members’ firsthand experiences and will produce important contributions. Findings suggest that gang members experience significant Black adolescent trauma; membership for Black women is familial, and as adults, they often use their gang identities to challenge gang culture; and there is a duality between “gang members” and “gang bangers.” I argue that this research debunks the narrative that gang members display inherent criminal behavior. Instead, I provide a counternarrative that humanizes gang members and adds validity to the structural causes of gang membership in these communities.
The Sinonasal Outcome Test–22 or European Position Paper: Which Is More Indicative of Imaging Results?
Authors: Zhou Allen S. , Prince Anthony A. , Maxfield Alice Z. , Corrales C. Eduardo , Shin Jennifer J.
Published: September 2020

Objective

The 22‐item Sinonasal Outcome Test (SNOT‐22) is a trusted measure of symptom severity in chronic rhinosinusitis. The European Position Paper on Rhinosinusitis (EPOS) provides widely accepted diagnostic criteria, which include sinonasal symptoms, their duration, and imaging results. Our objective was to compare these approaches to assessing symptoms to determine if either was more indicative of radiologic findings, to support decisions in telehealth.

Study Design

Observational outcomes study.

Setting

Tertiary care center.

Methods

In total, 162 consecutive patients provided a structured sinonasal history, completed the SNOT‐22, and underwent sinus computed tomography (CT) within 1 month. SNOT‐22 scores, EPOS‐defined symptom sets, and Lund‐Mackay results were assessed. To facilitate direct comparisons, we performed stepwise evaluations of sinonasal symptoms alone and combined with duration. The discriminatory capacity for imaging results was determined through areas under the receiver operating characteristic curves (ROC‐AUC) for dichotomous outcomes and ordinal regression for multilevel outcomes.

Results

In ROC‐AUC analyses, SNOT‐22 and EPOS‐defined symptoms had similar discriminatory capacity for Lund‐Mackay scores, regardless of duration. Within ordinal regression analyses, SNOT‐22 nasal scores were significantly associated with Lund‐Mackay scores, while EPOS‐defined nasal symptoms were not statistically significantly related.

Conclusions

SNOT‐22 nasal scores and EPOS‐defined nasal symptoms may have similar associations with imaging results when assessed via ROC‐AUC, while SNOT‐22 may have more association within ordinal data. Understanding the implications of discrete patterns of symptoms may confer benefit, particularly when in‐person and fiberoptic exams are limited.
Process Density Index (PDI) scores in typically developing children between 3;0 to 7;0 years of age: Evidence from Dravidian Tulu

Published: September 2020

Various speech metrics have been developed to assess and monitor phonological development in young children. Process Density Index (PDI) is one such measure employed to determine the severity of phonological errors and speech intelligibility. The present study explored the utility of PDI as a measure of phonological development in 756 Tulu-speaking children between 3;0–7;0 years, across age and gender groups. Results revealed that the youngest group of children exhibited a higher number of phonological processes and a higher PDI score as compared to the oldest group. Children with higher PDI scores exhibited poorer speech intelligibility than those with lower PDI Scores. Further, a statistically significant gender difference with boys exhibiting higher PDI scores than girls with no interaction between age and gender was noted. The study finding provides an insight into the phonological aspects specific to Tulu language and suggests the utility of PDI as a potential clinical measure while assessing phonological issues.
Prolonged thrombocytopenia in a neonate with Noonan syndrome: a case report
Authors: Li Meng , Zhang Jinghui , Sun Nianzheng
Published: September 2020

We report a case of a Chinese neonate who was diagnosed with Noonan syndrome and had persistent, self-limited thrombocytopenia. The neonate was admitted to the Neonatology Department 20 minutes after birth because of respiratory distress. From birth until 2 months of age, platelet values fluctuated between approximately 6 and 30 × 109/L. There was no intracranial hemorrhage. However, the child had a transient hypocalcemic seizure and fever. We excluded thrombocytopenia caused by perinatal asphyxia, immune thrombocytopenia, fetomaternal alloimmune thrombocytopenia, juvenile myelomonocytic leukemia, and chromosome 13, 18, and 21 trisomy syndromes. Despite treatment with anti-infective agents and transfusion of platelets and immunoglobulin, the platelet count did not return to the normal range. Genetic testing confirmed a PTPN11 gene mutation, which led to the diagnosis of Noonan syndrome. At 3 months of age, the platelet count gradually increased without intervention and returned to the normal range by 6 months. We speculate that the thrombocytopenia in this case was closely related to Noonan syndrome.
Serum cystatin C is closely associated with euthyroid Hashimoto’s thyroiditis in adult female Chinese patients
Authors: Qin Qiaojing , Yang Min , Ke Wencai , Zhao Jinying , Ding Heyuan
Published: September 2020

Objective

The aim of our study was to explore the association between serum cystatin C (CysC) and euthyroid Hashimoto’s thyroiditis.

Methods

There were 119 female euthyroid Hashimoto’s thyroiditis patients and 225 healthy controls who were recruited. Serum CysC, thyroid function, thyroid autoantibodies, fasting glucose, liver enzymes, and lipid profile were determined. Clinical parameters were compared between two groups.

Results

Serum CysC levels were significantly higher in euthyroid Hashimoto’s thyroiditis patients compared with controls. In the lowest, middle, and highest tertile groups of CysC, the percentage of Hashimoto’s thyroiditis was 15.9%, 34.2%, and 53.5%, respectively. The percentage of Hashimoto’s thyroiditis was significantly higher in the highest tertile than in the lowest and middle tertiles. Spearman’s correlation analysis showed that serum CysC levels were negatively correlated with free triiodothyronine (FT3), and positively correlated with serum thyroid peroxidase antibody (TPOAb) and thyroglobulin antibody (TGAb). Logistic regression analysis showed that serum CysC was independently related to the status of euthyroid Hashimoto’s thyroiditis.

Conclusions

The present study shows the first evidence suggesting that serum CysC levels are positively correlated with TPOAb and TGAb. Serum CysC might underlie the pathophysiologic features of euthyroid Hashimoto’s thyroiditis.
A case of different gene mutations in primary and metastatic lesions after EGFR-TKI treatment of lung cancer
Authors: Xie Shaonan , Deng Huiyan , Liu Guangjie , Liu Qingyi
Published: September 2020

Background:

It remains controversial whether patients with EGFR-mutant lung adenocarcinoma should stop using epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) after progression during treatment.

Case report:

We report a 35-year-old man with poorly differentiated adenocarcinoma of the left upper lobe and an exon 19 deletion (Ex19Del) mutation found by large-panel next-generation sequencing. The patient underwent video-assisted thoracoscopic surgery 12 months after oral administration of icotinib 125 mg tid, and the left upper lobe and surrounding lymph nodes were removed. Postoperative pathology supported a diagnosis of left upper lobe adenocarcinoma and subcarinal (1/2), main pulmonary artery window (1/2), and left hilar (1/2) lymph node metastases. The EGFR mutations in the residual lesions had disappeared, and Ex19Del mutations were still visible in the mediastinal lymph node metastasis.

Conclusion:

Spatial heterogeneity of the resistance mechanism may explain why patients who continue to receive EGFR-TKIs in combination with local therapies (e.g., radiotherapy) for progressing lesions may benefit even after progression during EGFR-TKI therapy. The loss of the EGFR mutation allele as a putative resistance mechanism requires additional preclinical and clinical confirmation.
SUNCT/SUNA in children and adolescents: Application of ICHD-3 criteria and treatment response: Case series of 13 SUNCT/SUNA pediatric cases
Authors: Qaiser Sharoon , Hershey Andrew D , Kacperski Joanne
Published: September 2020

Introduction

Trigeminal autonomic cephalalgias (TACs) are characterized by paroxysmal attacks of unilateral primary headaches associated with ipsilateral craniofacial autonomic symptoms. In this pediatric case series, 13 cases of short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT)/short-lasting unilateral neuralgiform headache with autonomic symptoms (SUNA), including children ages 3–18 years, are discussed. This paper reviews the application of International Classification of Headache Disorders, 3rd edition (ICHD-3) criteria especially in children presenting with SUNCT or SUNA. This is the largest pediatric case series of SUNCT/SUNA reported in the literature.

Background

Trigeminal autonomic cephalalgias are rare in children and adolescents, with SUNCT/SUNA having the least reported cases. We will discuss the application of ICHD-3 criteria to diagnose SUNCT/SUNA in children and review overlapping cases and their response to different treatment options including indomethacin, which is typically reserved for specific subtypes of TACs; for example, paroxysmal hemicrania.

Conclusion

This case series presents a unique opportunity to aid in the diagnosis and treatment of similar pediatric cases in the future. It helps us to broaden the ICHD-3 criteria to diagnose and treat different overlapping trigeminal autonomic cephalalgia cases in children.

Only surgery led to a real improvement of his condition.
How Residential Care Staff Conceptualize the Identities of Residents With Dementia and Its Relevance for Decision Making
Authors: Cameron Nadine , Fetherstonhaugh Deirdre , Bauer Michael , Tarzia Laura
Published: September 2020

The ways in which residential aged care staff conceptualize the identities of residents with dementia has significance for how they support them to make decisions and make decisions on their behalf. This article aims to further understand how staff in residential aged care facilities comprehend who residents “are.” Methods: This qualitative study draws on individual and group interview data with aged care staff from two Australian states concerning decision making for individuals with dementia. It identifies themes relevant to how staff refer to identity in relation to such residents. Results: Staff possess disparate ideas about what things comprise residents’ identities and, accordingly, which sources of knowledge are most relevant to learning about residents. Discussion: This article argues for the application of a multidimensional and temporally inclusive understanding of identity by those who provide care to people with dementia.

Cet article retrace le cheminement intellectuel qui a conduit, moins spontanément qu’on ne pourrait le croire, Christine Musselin à faire sa thèse puis à devenir chercheuse au Centre de Sociologie des Organisations, et à consacrer ses recherches à l’étude comparative des systèmes d’enseignement supérieur à travers la gouvernance des universités, les politiques universitaires et les marchés du travail universitaires, mêlant ainsi sociologie des organisations, analyse des politiques publiques et sociologie économique. Il montre comment l’étude de la coopération a été le fil rouge de ses travaux, et l’analyse sociologique des organisations, basée sur les entretiens organisationnels, une méthode heuristique pour la plupart des enquêtes qu’elle a menées.
The Influence of Structural Characteristics and Street Codes on Violent Female Offenders: A Decade After Anderson’s Initial Observations
Authors: Erickson Jacob H. , Burgason Kyle A.
Published: September 2020

A large number of studies have examined predictors of female crime quantities yet considerably less attention has been directed toward exploring patterns in the nature or quality of female violence within and across communities. Although research consistently demonstrates that females engage in less criminal behavior than males, research on the variability across contexts is somewhat sparse. The authors conduct analyses to determine if Anderson’s initial observations of female violence in neighborhoods inundated with the code of the streets persist a decade after his initial ethnographic account. Specifically, we examine incident-level data from the National Incident Based Reporting System with contextual-level data on the cities in which the incidents occurred. We use hierarchical linear and nonlinear modeling techniques to explore variations in predictors of offender gun use and extent of victim injury in violent female encounters. Supporting Anderson’s initial accounts for street females and prior research we find the probability of gun usage and level of victim injury is not significantly influenced by differences in community context, and specifically not exacerbated by the types of conditions that make the code of the street locally salient.
Chemokine receptors on peripheral blood T lymphocytes in children on peritoneal dialysis
Authors: Szczepańska Maria , Sędek Łukasz , Bulsa Joanna , Mazur Bogdan , Zwolińska Danuta , Tkaczyk Marcin , Karpe Jacek , Szczepański Tomasz
Published: September 2020

Background:

Immune cell dysfunction is listed among complications resulting from chronic kidney disease (CKD). It could be associated with T-cells, which play a role in the lymphocytic migration and infiltration. However, the data on chemokine receptors expression on T-cells in patients with CKD particularly treated with peritoneal dialysis (PD) are still limited.

Methods:

The study aimed at multiparameter flow-cytometric analysis of the absolute numbers and percentage of T-cell subsets with surface chemokine receptors (CCR4, CCR5, CCR7, CXCR3, and CXCR4) or receptors’ combinations in 47 children treated with PD.

Results:

We found lower absolute numbers of total T lymphocytes, lymphocytes with surface CCR5, CXCR4+CCR5, CXCR3+CCR5 antigens and T-cells with CCR4, CCR4+CD4, CXCR3, CXCR3+CD4, and CD8 receptors. Lymphocytes T with CD4, CCR7, CD28+CCR7, CXCR3+CD8 antigens showed higher percentage in children on PD as compared to healthy children and opposite percentage values of CCR4+, CCR4+CD4+, CXCR3+ T lymphocytes were diminished. Mean fluorescent intensity for CCR7+, CCR7+CD45RO+, CCR7+CD28+, CXCR4+CD4+, CCR5+CD4+, CCR4+, CCR4+CD4+ T-cells was lower in the PD group than in healthy children. The analysis of correlation between T lymphocyte subpopulations with chemokine receptors and other parameters revealed positive correlation of CCR7+ and CCR7+CD28+ T-cells and weekly creatinine clearance, negative correlation between the percentage of CD45RO+CCR7 antigen positive T-cells and KT/Vurea.

In conclusion, we could not confirm the phenomenon of earlier senescence of T-cells in children with CKD on PD treatment. This still requires further investigation. The higher percentage of T-cells with CCR7 surface receptor could be responsible for the increase of proliferation activity in this group of children.
How Midlife Chronic Stress Combines with Stressful Life Events to Influence Later Life Mental and Physical Health for Husbands and Wives in Enduring Marriages
Authors: Wickrama Kandauda A. S. , Klopack Eric T. , O’Neal Catherine W.
Published: September 2020

Objectives: To investigate how midlife chronic stress (40–50 years) and subsequent acute stressful events (50–65 years) influence husbands’ and wives’ later life mental and physical health (65+ years). Methods: Dyadic structural equation modeling was used with prospective data over 25 years from 256 husbands and wives in enduring marriages. Results: For both spouses, midlife chronic stress influenced the occurrence of subsequent acute stressful life events, which in turn influenced both depressive symptoms and poor physical health in later years. For both spouses, midlife chronic stress also directly influenced depressive symptoms. Wives’ midlife chronic stress also directly influenced their own poor physical health and husbands’ depressive symptoms in later years. Discussion: These findings enhance our knowledge about the long-term joint influence of midlife chronic stress and acute stressful life events on health outcomes of husbands and wives in later years and identify dependencies between spouses, which can inform health preventive intervention programs.
The strategic transformation of accounting into a learned profession
Authors: Aldredge Melissa , Rogers Courtenay , Smith James
Published: September 2020

The skills gap in the accounting profession is not a new issue. More than 30 years of research and studies all point to an ever-increasing disparity between what accountants do and what the mainstream accounting curriculum teaches. Technology and businesses are changing and evolving rapidly, as are the expectations for accountants. Advances in the areas of automation and machine learning, artificial intelligence, data analytics and blockchain are examples of current technology disruptions in the accounting industry. The competencies and skills needed today for the accounting profession in the broad sense are not being taught by most universities. The purpose of this paper is to explore what these competencies and skills are, and why accounting curricula needs a strategic transformation into higher education for a learned profession.
The effectiveness of human papillomavirus load, reflected by cycle threshold values, for the triage of HPV-positive self-samples in cervical cancer screening
Authors: Song Fangbin , Du Hui , Wang Chun , Huang Xia , Qu Xinfeng , Wei Lihui , Belinson Jerome L , Wu Ruifang ,   CHIMUST team
Published: September 2020

Objective

The performance of Cobas4800 cycle threshold value (Ct-value, reflecting viral load) combined with human papillomavirus (HPV) 16/18 genotyping was explored as a method of risk stratification to triage patients after primary HPV screening of self-collected samples.

Methods

The Chinese Multi-site Screening Trial database was reviewed, with focus on self-collected samples, using the results of Cobas4800 HPV assay. Quartiles of Ct-values of each genotype were used for grouping and developing screening algorithms. Diagnostic accuracy for paired comparisons between algorithms was obtained using McNemar’s test.

Results

A total of 10,498 women were included. The Ct-values of HPV16 and other high-risk HPV were inversely correlated with the severity of cervical lesions ( p < 0.001). Risks for cervical intraepithelial neoplasia (CIN2+/CIN3+) were significantly stratified by Ct-values from channels detecting HPV16 and other high-risk HPV types. “HPV with HPV16/18 and reflex Ct <33.7” (algorithm G) achieved a favorable sensitivity to “HPV with atypical squamous cells of undetermined significance or worse (≥ASCUS)” (81.9% vs. 70.1% for CIN2+, p < 0.001), a comparable sensitivity to “HPV with HPV16/18 reflex cytology ≥ASCUS” (81.9% vs. 81.3% for CIN2+, p > 0.05), and resulted in a slightly lower specificity than the latter two algorithms (92.6% vs. 97.4% and 95.4% respectively for CIN2+, p < 0.05). However, algorithm G achieved a comparable sensitivity to HPV testing alone for CIN3+, and reduced the colposcopy referral rate from 13.7% for HPV testing alone to 8.4%.

Conclusions

HPV viral loads reflected by Ct-values are associated with the severity of cervical lesions. Ct-values with an appropriate cut-off of 33.7, combined with HPV16/18 genotyping, represent a promising triage of HPV-positive women particularly for self-collected samples.
What is wellness? The role of human values
Authors: Crowe Jonathan
Published: September 2020

There is a growing literature on wellness for law in Australia and elsewhere. Significant uncertainty exists, however, about what exactly wellness means in this context. I argue that wellness is not best understood either as the absence of psychological distress or as the presence of life satisfaction or positive affect. I propose an alternative understanding of wellness that centres around the role of basic values in human flourishing. Wellness, I suggest, consists in participating in the various dimensions of human flourishing in a balanced and integrated way. This approach draws out the deep challenges that wellness poses to legal education and practice.
Radiographic and Clinical Outcomes of Hallux Valgus and Metatarsus Adductus Treated With a Modified Lapidus Procedure
Authors: Conti Matthew S. , Caolo Kristin C. , Ellis Scott J. , Cody Elizabeth A.
Published: September 2020

Background:

Previous studies have found an increased rate of deformity recurrence in hallux valgus (HV) patients with concomitant metatarsus adductus (MA) undergoing metatarsal osteotomies. The purpose of this paper was to determine if there were radiographic or clinical outcome differences between HV patients with and without MA undergoing a modified Lapidus procedure.

Methods:

One hundred forty-seven feet that underwent a modified Lapidus procedure for HV were divided into 2 groups based on their preoperative modified Sgarlato’s angle: (1) the MA group had an angle ≥20 degrees and (2) the HV-only group had an angle <20 degrees. HV angle (HVA) and intermetatarsal angle (IMA) were measured on preoperative and ≥5-month postoperative weightbearing radiographs. Patient-Reported Outcome Measurement Information System (PROMIS) physical function (PF) and pain interference (PI) scores were obtained preoperatively and postoperatively.

Results:

Patients in the MA group had a significantly higher mean postoperative HVA (10.8 vs 7.5 degrees; P = .038). There was a trend toward higher PROMIS PI scores in the MA group at 1 year postoperatively (51.9 vs 47.6; P = .088). Patients in the MA group were more likely to have a revision surgery (7.3% vs 0%; P = .021), and there was a trend toward those patients having a higher recurrence rate (17.1% vs 6.6%; P = .064).

Conclusion:

Despite potentially worse postoperative outcomes in patients with HV and MA who undergo a modified Lapidus procedure, the recurrence rates reported here are lower than those reported in the literature for patients with MA undergoing metatarsal osteotomies, indicating that a modified Lapidus procedure may be an acceptable choice in these patients.

Level of Evidence:

Level III, retrospective comparative series.
Impact of Early Fluid Balance on 1-Year Mortality in Critically Ill Patients With Cancer: A Retrospective Study in Central Taiwan
Authors: Chen Yung-Chun , Zheng Zhe-Rong , Wang Chen-Yu , Chao Wen-Cheng
Published: September 2020

A positive fluid balance has been found to be deleterious in critically ill patients; however, the impact of early fluid balance, particularly on long-term outcomes, in critically ill patients with cancer remains unclear. We performed this retrospective study at a tertiary-care referral hospital with 1500 beds and 6 intensive care units (ICUs) in central Taiwan, and 942 patients with cancer admitted to ICUs during 2013 to 2016 were enrolled. The primary outcome was 1-year mortality. Cancer-related data were obtained from the cancer registry, and data during ICU admissions were retrieved from the electronic medical records. The association between fluid balance, which was represented by median and interquartile range, and 1-year mortality was determined by calculating the hazard ratio (HR) with 95% confidence interval (CI) using a multivariable Cox proportional hazards regression model. The in-hospital mortality rate was 22.9% (216 of 942), and the mortality within 1 year after the index ICU admission was 38.7% (365 of 942). Compared to survivors, nonsurvivors tended to have a higher Acute Physiology and Chronic Health Evaluation II score (24.1 ± 6.9 vs 20.5 ± 6.2, P < .01), a higher age (65.0 ± 14.4 vs 61.3 ± 14.3, P < .01), a higher serum creatinine (1.5 ± 1.3 vs 1.0 ± 1.0, P < .01), and a higher cumulative day 1 to 4 fluid balance (2669, 955-5005 vs 4103, 1268-7215 mL, P < .01). Multivariable Cox proportional hazards regression analysis found that cumulative day-4 fluid balance was independently associated with 1-year mortality (adj HR 1.227, 95% CI: 1.132-1.329). A positive day 1 to 4 cumulative fluid balance was associated with shorter 1-year survival in critically ill patients with cancer. Further studies are needed to validate this association.
Denosumab for Effective Tumor Size Reduction in Patients With Giant Cell Tumors of the Bone: A Systematic Review and Meta-Analysis
Authors: Yayan Josef
Published: September 2020

Background:

Denosumab is a human monoclonal antibody that has been used successfully in the treatment of giant cell tumors of bone. These tumors are rare and, in principle, benign, but they are highly aggressive, locally advanced, osteolytic bone tumors that can metastasize to the lungs. Denosumab is an effective treatment when these tumors cannot be surgically removed or when surgical resection is likely to lead to severe morbidity (eg, loss of limbs or joints). The aim of this systematic review and meta-analysis was to investigate patients with giant cell tumors of bone who experienced tumor progression during treatment with denosumab and to compare them with patients who experienced reduction of their giant cell tumors of bone during treatment with denosumab.

Methods:

Embase, Cochrane Library, and MEDLINE/PubMed databases were searched for trials submitted by January 7, 2020, that reported the efficacy and safety of denosumab in patients with giant cell tumors of bone.

Results:

Sixty studies were reviewed, involving a total of 1074 patients who had giant cell tumors of bone and were treated with denosumab. Of the 60 studies, 58% of the patients were from case series studies, 39% from open-label phase II studies, and 3% from case reports. The response rate for denosumab as a treatment for giant cell tumors of bone was 97.5%, with statistical significance ( P < .0001). Pain in the limbs was statistically the most common adverse event for denosumab treatment in case series studies ( P < .0001). No treatment-related deaths occurred in the reviewed studies.

Conclusion:

Cumulative evidence supports the addition of surgery to optimal medical therapy with denosumab to reduce tumor size, clinical symptoms, and mortality among patients with giant cell tumors of bone.
A Scholar’s Reflection on Intimate Partner Violence in the Cape Verdean Community
Authors: Thomas Dawna Marie
Published: September 2020

The #MeToo and Time’s Up movements have sparked a significant cultural shift in the United States around sexual harassment and abuse by creating an environment of support, rather than one that punishes and silences women and men who come forward to tell their stories about abuse of all kinds. The Cape Verdean community faces a variety of complex challenges and barriers in addressing intimate partner violence. This article chronicles my experiences reporting the study findings from the Cape Verdean Women’s Project (CVWP), which included Cape Verdean women’s perceptions of intimate violence and their recommendations for social change.
Electoral incentives to coalition formation in multiparty presidential systems
Authors: Borges André , Turgeon Mathieu , Albala Adrián
Published: September 2020

Coalition theories of presidential regimes have frequently assumed that coalition formation is a mostly post-electoral phenomenon. We challenge this view by showing that pre-electoral bargaining shapes to a substantial extent minority presidents’ disposition to cooperate with the legislature by forming a majority cabinet. Examining a dataset of pre- and post-electoral coalitions from 18 Latin American countries, we find that majority coalition cabinets are more likely to occur when elected presidents form pre-electoral coalitions (PECs), to the extent that pre-electoral agreements create stronger incentives for cooperation, by relying on a broader set of rewards than any post-electoral agreement. Moreover, we find that the likelihood of majority coalition formation increases as the share of PEC seats increases, thus reducing the need to engage in post-electoral bargaining. Our findings carry important implications for the study of cabinet formation in presidential regimes by introducing pre-electoral agreements as a key determinant of cabinet formation.
Novel use of existing technology: A preliminary study of patient portal use for telerehabilitation
Authors: Conroy Susan S , Harcum Stacey , Keldsen Linda , Bever Christopher T
Published: September 2020

Patient portals (PPs) foster engagement and self-management of chronic disease and are emerging as extensions of the care continuum. Utilisation from a health service delivery perspective is growing; however, it is a relatively new model of care in the field of rehabilitation. This pilot, within a larger randomised controlled stroke rehabilitation trial, explored the feasibility and acceptance of secure messaging using an established nationwide PP system for e-visits. Fifteen participants with stroke-related arm disability were randomised to 6 weeks of home arm telerehabilitation. All were over the age of 60 and 73% lived with a spouse or significant other. Mean intervention time was 6.8 weeks, and participants sent 2.3 ± 1.4 messages per week to complete 15.1 h of reported therapy (prescribed therapy = 18 h). Portal use improved therapist efficiency and resulted in a 1:6 therapist to patient exercise time ratio compared with the conventional 1:1 ratio for in-person therapy. Low initial electronic health literacy, self-efficacy or cognitive scores did not prohibit utilisation, and satisfaction with secure messaging for patient–therapist communication was 3.5 ± 1.2 out of 5. Overall, PP-supported e-visits were a feasible and acceptable telerehabilitation care delivery method for this chronic stroke population.

Reimagining the terrain of liquid times: Reflexive marketing and the sociological imagination
Authors: Hewer Paul
Published: September 2020

This paper has three objectives. The first is to deliver a critical review of the work of Zygmunt Bauman on Liquid Modernity and Liquid Times. I argue that Bauman’s work can provide a useful starting point for analysing the ‘unruly’ forces of contemporary society. Bauman’s work, as I have sought to reveal, takes us to the heart of liquid modern darkness. It forces us to take seriously the import of the sociological imagination and the insight that personal troubles are best understood as emerging public issues stemming from structural processes. The second objective, is to explore how consumer culture theorists have taken and in dialogue with these ideas sought to expand upon his initial ideas. Here I review the value of the concept of ‘liquid consumption’ and the ‘fresh start mindset’. The third and final objective, is to demonstrate how reflexive marketing practitioners are responding to such liquid times through rethinking their practice and thereby extending the terrain of marketing. Here I detail how the promise marketing imagination starts not with the darkness of liquid modern times but rather with a far more hope inspired tale to enchant new markets and new audiences on the possibilities and ‘solutions’ of being future oriented and technologically savvy. Finally, it argues that the task of reimagining appears essential given the current zeitgeist, where the climate of anxiety, fear and uncertainty whether it be political, economic, environmental or social threatens to engulf us.
