Understanding the priorities of residents, family members and care staff in residential aged care using Q methodology: a study protocol
Authors: Ludlow Kristiana , Churruca Kate , Ellis Louise A , Mumford Virginia , Braithwaite Jeffrey
Published: March 2019

Introduction

Residential aged care facilities (RACFs) are under increasing pressure to provide high-quality, round the clock care to consumers. However, they are often understaffed and without adequate skill mix and resources. As a result, staff must prioritise care by level of importance, potentially leading to care that is missed, delayed or omitted. To date, the literature on prioritisation and missed care has been dominated by studies involving nursing staff, thereby failing to take into account the complex networks of diverse stakeholders that RACFs comprise. This study aims to investigate the priorities of residents, family members and care staff in order to make comparisons between how care is prioritised in RACFs by the different stakeholder groups.

Methods and analysis

This study comprises a Q sorting activity using Q methodology, a think-aloud task, a demographics questionnaire and semi-structured interview questions. The study will be conducted in five RACFs across NSW and QLD, Australia. Using purposive sampling, the project will recruit up to 33 participants from each of the three participant groups. Data from the Q sorting activity will be analysed using the analytic software PQMethod to identify common factors (shared viewpoints). Data from the think-aloud task and semi-structured interviews questions will be thematically analysed using the Framework Method and NVivo qualitative data analysis software.

Ethics and dissemination

The study has been approved by St Vincent’s Health and Aged Care Human Research and Ethics Committee and Macquarie University Human Research Ethics Committee. It is expected that findings from the study will be disseminated: in peer-reviewed journals; as an executive report to participating facilities and a summary sheet to participants; as a thesis to fulfill the requirements of a Doctor of Philosophy; and presented at conferences and seminars.
Reducing red blood cell folate testing: a case study in utilisation management
Authors: Ismail Ola , Chin-Yee Ian , Gob Alan , Bhayana Vipin , Rutledge Angela
Published: March 2019

Mandatory enrichment of wheat flour in Canada with folic acid since 1998 has caused folate deficiency to be rare. There were 3019 red blood cell (RBC) folate tests performed during an 18-month period at London Health Sciences Centre (LHSC)/St. Joseph’s Healthcare London (SJHC) without any folate deficiency detected. We implemented a quality improvement initiative to reduce RBC folate testing at LHSC/SJHC. We began with a retrospective review of RBC folate tests performed during the previous 18 months. We identified physicians who had ordered more than five tests during this period and sent them an educational email to inform them of our intentions and solicit their input. We then discontinued RBC folate testing in-house and a pop-up window was introduced to the computerised physician order entry system stating that biochemist approval would be needed before samples would be sent out for testing. During the audited 18-month period, the average monthly test volume was 168 (SD 20). The three departments ordering the most RBC folate testing were nephrology (15%), haematology (7%) and oncology (7%). Physician feedback was supportive of the change, and during the 2 months after targeted email correspondence, the average monthly test volume decreased 24% (p<0.01) to 128 (SD 1). On discontinuation of the test in-house and implementation of the pop-up, the average monthly test volume decreased another 74% (p<0.01) to 3 (SD 2). In the 10 months following discontinuation of the test on-site, there were only 39 RBC folate tests performed with no deficiency detected. This initiative significantly reduced unnecessary RBC folate orders. The change in ordering on email contact suggests that physician education was an important factor reducing overutilisation. However, the most significant decrease came from restricting the test so that only orders approved by a biochemist would be performed.

Published: March 2019

The Tantalus Oscillator is a nonlinear hydrodynamic oscillator with an attractive limit cycle. In this study, we pursue the construction of a biparametric bifurcation diagram for the Tantalus Oscillator under biphasic perturbations. That is the first time that this kind of diagram is built for this kind of oscillator under biphasic perturbations. Results show that biphasic perturbations have no effect when the coupling time is chosen over a wide range of values. This modifies the bifurcation diagram obtained under monophasic perturbations. Now we have the appearance of periodic increment Big Bang Bifurcations. The theoretical results are in excellent agreement with experimental observations.
Pattern Dynamics of an SIS Epidemic Model with Nonlocal Delay

Published: March 2019

In this paper, we study an SIS epidemic model with nonlocal delay based on reaction–diffusion equation. The spatiotemporal distribution of the model solution is studied in detail, and sufficient conditions for the occurrence of the Turing pattern were obtained using the analysis of Turing instability. It was found that the delay not only prohibited the spread of infectious disease, but also had great effects on the spatial steady-state patterns. More specifically, the spatial average density of the infected populations will decrease, as well the width of the stripe pattern will increase as delay increases. When the delay increases to a certain value, the stripe pattern changes to the mixed pattern. The results in this work provide new theoretical guidance for the prevention and treatment of infectious diseases.
The Spence Shale Lagerstätte: an important window into Cambrian biodiversity
Authors: Kimmig Julien , Strotz Luke C. , Kimmig Sara R. , Egenhoff Sven O. , Lieberman Bruce S.
Published: March 2019

The Spence Shale Member of the Langston Formation is a Cambrian (Miaolingian: Wuliuan) Lagerstätte in northeastern Utah and southeastern Idaho. It is older than the more well-known Wheeler and Marjum Lagerstätten from western Utah, and the Burgess Shale from Canada. The Spence Shale shares several species with these younger deposits, yet it also contains a remarkable number of unique species. Because of its relatively broad geographical distribution, and the variety of palaeoenvironments and taphonomy, the fossil composition and likelihood of recovering weakly skeletonized (or soft-bodied) taxa varies across localities. The Spence Shale is widely acknowledged not only for its soft-bodied taxa, but also for its abundant trilobites and hyoliths. Recent discoveries from the Spence Shale include problematic taxa and provide insights about the nature of palaeoenvironmental and taphonomic variation between different localities.

Governance, risk, and compliance (GRC) managers often struggle to document the current state of their organizations. This is due to the complexity of their IS landscape, the complex regulatory and organizational environment, and the frequent changes to both. GRC tools seek to support them by integrating existing information sources. However, a comprehensive analysis of how the data is managed in such tools, as well as the impact of data quality, is still missing. To build a basis of empirical data, we conducted a series of interviews with information security managers responsible for GRC management activities in their organizations. The results of a qualitative content analysis of these interviews suggest that decision makers largely depend on high-quality documentation but struggle to maintain their documentation at the required level for long periods of time. This work discusses factors affecting the quality of GRC data and information and provides insights into approaches implemented by organizations to analyze, improve, and maintain the quality of their GRC data and information.
Lynch Syndrome: From Screening to Diagnosis to Treatment in the Era of Modern Molecular Oncology
Authors: Cohen Stacey A. , Pritchard Colin C. , Jarvik Gail P.
Published: March 2019

Lynch syndrome is a hereditary cancer predisposition syndrome caused by germline alterations in the mismatch repair genes and is the most common etiology of hereditary colorectal cancer. While Lynch syndrome was initially defined by the clinical Amsterdam criteria, these criteria lack the sensitivity needed for clinical utility. This review covers the evolution of screening for Lynch syndrome from the use of tumor microsatellite instability and/or somatic alterations in mismatch repair protein expression by immunohistochemistry to the newest methods using next-generation sequencing. Additionally, it discusses the clinical implications of the diagnosis of Lynch syndrome as it affects cancer therapeutics and the role of screening in noncolorectal Lynch-associated cancers. As molecular oncology continues to evolve, it is crucial to remain current on the increasing complexity of Lynch syndrome diagnostics and treatment options.
Applications of DFT + DMFT in Materials Science
Authors: Paul Arpita , Birol Turan
Published: March 2019

First-principles methods can provide insight into materials that is otherwise impossible to acquire. Density functional theory (DFT) has been the first-principles method of choice for numerous applications, but it falls short of predicting the properties of correlated materials. First-principles DFT + dynamical mean field theory (DMFT) is a powerful tool that can address these shortcomings of DFT when applied to correlated metals. In this brief review, which is aimed at nonexperts, we review the basics and some applications of DFT + DMFT.

Influenza A virus (IAV) poses a constant worldwide threat to human health. Although conventional vaccines are available, their protective efficacy is type or strain specific, and their production is time-consuming. For the control of an influenza pandemic in particular, agents that are immediately effective against a wide range of virus variants should be developed. Although pretreatment of various Toll-like receptor (TLR) ligands have already been reported to be effective in the defense against subsequent IAV infection, the efficacy was limited to specific subtypes, and safety concerns were also raised. In this study, we investigated the protective effect of an attenuated bacterial outer membrane vesicle ­harboring modified lipid A moiety of lipopolysaccharide (fmOMV) against IAV infection and the underlying mechanisms. Administration of fmOMV conferred significant protection against a lethal dose of pandemic H1N1, PR8, H5N2, and highly pathogenic H5N1 viruses; this broad antiviral activity was dependent on macrophages but independent of neutrophils. fmOMV induced recruitment and activation of macrophages and elicited type I IFNs. Intriguingly, fmOMV showed a more significant protective effect than other TLR ligands tested in previous reports, without exhibiting any adverse effect. These results show the potential of fmOMV as a prophylactic agent for the defense against influenza virus infection.

Background: Postinfarction ventricular septal rupture (PI-VSR) is a rare but devastating complication of acute myocardial infarction (AMI). Risk stratification in the acute phase is crucial for decision-making, and this study analyzed the risk factors for early mortality and the effects of various management options on the outcome of PI-VSR patients in the era of percutaneous intervention. Methods: A total of 96 patients with PI-VSR were identified and divided into an acute-phase survivor group (n = 46, survived ≥2 weeks after admission) and a nonsurvivor group (n = 50, died within 2 weeks after admission). Percutaneous closure was considered in acute-phase survivors. Patients were followed up for a mean 47 (quartiles 15–71) months by clinical visit or telephone interview. Results: The overall acute-phase (i.e., < 2 weeks after the diagnosis of PI-VSR) mortality rate was 52%. Female sex and Killip Class III–IV at admission were associated with an increased risk of acute-phase death. Of the 46 patients who survived ≥2 weeks, 20 underwent interventional occlusion and the procedure was successful in 19. Percutaneous closure in the acute-phase survivor group improved the immediate (21% in-hospital mortality rate) and long-term (53% mortality) outcomes. Conclusions: Patients with PI-VSR are at a high risk of acute-phase mortality. Female sex and severe cardiac dysfunction at admission are linked with a high rate of acute-phase deaths. Percutaneous closure in acute-phase survivors results in favorable short- and long-term benefits for PI-VSR patients.

Background/Aims: Bile acids have recently been associated with the pathogenesis of irritable bowel syndrome (IBS). We therefore evaluated the expression of bile acid receptors in the intestinal mucosa of IBS patients as well as the effects of bile acids on small intestinal epithelial cells. Methods: Intestinal biopsy specimens were obtained from 15 IBS patients and 15 healthy controls. The effects of bile acid stimulation on trans-epithelial electrical resistance (TEER) and permeability in differentiated Caco-2 cells were measured. Proinflammatory cytokines were measured by enzyme-linked immunosorbent assay. mRNA levels of bile acid receptors, including farnesoid X receptor (FXR), and cytokines were determined by real-time reverse transcription-PCR. Caco-2 cells were pre-incubated with the FXR antagonist guggulsterone. Results: FXR mRNA expression at the terminal ileum was increased in IBS patients. Chenodeoxycholic acid (CDCA) significantly decreased TEER, increased permeability, and increased interleukin-8 (IL-8) release from Caco-2 cells. Pre-incubation with guggulsterone blocked CDCA-mediated IL-8 release; however, the decrease in TEER was not reversed. CDCA-induced IL-6 and IL-8 mRNA levels were blocked by guggulsterone. CDCA increased IL-6, tumor necrosis factor-α (TNF-α), and vascular endothelial growth factor release, whereas guggulsterone significantly blocked IL-6 and TNF-α release. Conclusions: FXR expression was elevated at the terminal ileum in IBS patients. CDCA increased proinflammatory cytokines, while guggulsterone blocked these increases.

Published: March 2019

Objectives: To analyze outcomes of patients > 85 years with de novo bladder cancer (BCa). To compare outcomes of high grade (HG) non-muscle invasive BCa (NMIBC) treated with standard therapies versus palliative management. Methods: Retrospective revision of 65 patients > 85 years who underwent transurethral resection of the bladder (TURB) for de novo BCa. According to functional status each patient was offered a standard or palliative management after TURB. Results: Median age was 87.3 years (85.2–95.4) and 51 were men (78.5%). Twenty-eight (43%) were American Society of Anesthesiologists (ASA) II and 37 ASA III–IV (57%). Pathological examination: 29 pTx-pTa (44.6%), 28 pT1 (43.1%) and 8 pT2 (12.3%). Twenty were low grade (30.8%) and 45 HG (69.2%). Among 37 HG NMIBC patients, 43% followed standard therapies (BCG or re-staging TURB + BCG), and 57% a palliative management (no oncological treatments). With a median follow-up of 20 months (3–108), 2 (12.5%) died in standard group compared to 11 (52.4%) in palliative. In univariate analysis, age (p = 0.024), stage (p = 0.009), and standard management (p = 0.019) were related to overall survival (OS). In multivariate, standard management was an independent prognostic factor of OS (hazard ratio 0.164, 95% CI 0.036–0.744, p = 0.048). Conclusions: Advanced age should not be a contraindication for standard therapies in BCa. A geriatric assessment could identify patients who may benefit from adjuvant therapies after TURB.
Sacubitril/Valsartan and Mexiletine: A Proarrhythmic Combination?
Authors: Weir Robin A.P.
Published: March 2019

The uptake of sacubitril/valsartan since the PARADIGM study confirmed its beneficial effects on outcomes over enalapril in chronic systolic heart failure has inevitably led to potential interactions with co-prescribed medications in real-world patients. We report two cases that raise the possibility of an interaction between sacubitril/valsartan and the class Ib anti-arrhythmic mexiletine resulting in proarrhythmic effects. We discuss the pharmacokinetics of both agents and posit potential mechanistic interactions that suggest caution should be used and careful monitoring for (ventricular) arrhythmias applied in patients receiving sacubitril/valsartan and mexiletine.

Published: March 2019

Introduction: The presence of positive para-aortic lymph nodes in advanced cervical cancer remains the most important prognostic factor for survival and also defines the treatment. Our aim was to define the influence of staging para-aortic lymphadenectomy in patients’ survival. Material and Methods: The medical records of 74 patients with advanced cervical cancer (FIGO IIB-IVA) were reviewed. In 31 patients (41.9%), the assessment of lymph nodes was performed with imaging test (group 1) and in 43 (58.1%) within a surgical staging para-aortic lymphadenectomy (group 2). We compared both groups according to stage of disease, treatment, progression-free survival (PFS), and overall survival (OS). Results: The extended-field radiotherapy was performed in 44.2 and 19.4% of patients in surgical and imaging staging group, respectively (p = 0.045). The disease-free survival rate was 17.4 ± 17.4 months in group 1 and 14.4 ± 12.6 months in group 2 (p = 0.456). No differences in OS were found between these 2 groups (p = 0.676). Conclusions: Despite the higher diagnostic accuracy of surgical staging and the higher number of patient who received extended field radiotherapy, we did not find differences between the overall and PFS rates in both the studied groups. Further prospective study on a higher number of patients would be necessary.

Background and Aims: We examined the efficacy of the combined use of L-menthol spraying (L-mentholS) as an antispasmodic agent and carbon dioxide insufflation (CO2I) on the adenoma detection rate (ADR) in a prospective, single-center trial with a 2 × 2 factorial design. Methods: We randomly assigned 611 patients scheduled to undergo colonoscopy to 4 groups: (1) the L-mentholS + CO2I (n = 153), (2) L-mentholS + air insufflation (AI; n = 156), (3) CO2I (n = 153), and (4) AI (n = 149) groups. We used 20 mL of 0.8%-L-menthol solution for the L-mentholS. The primary outcome was the difference in the ADR, and the secondary outcomes were the differences in colonic peristalsis and abdominal pain. ­Results: The ADRs were not different among the groups: 1/2/3/4; 39.9%/43.6%/41.2%/51.0%. CO2I was associated with a significant decrease in the ADR (OR 0.57; 95% CI 0.35– 0.93) with a multiple logistic regression. The interaction between L-mentholS and CO2I was associated with a suppression of the decrease in the ADR. Both L-mentholS and CO2I were associated with a significant decrease in abdominal pain, and L-mentholS was associated with a significant improvement of peristalsis. Conclusions: The fact that CO2I was associated with significant decreases in the ADR was a problem. The combined use of L-mentholS and CO2I could help to suppress the decrease in the ADR.

Background:

Reentrant ventricular arrhythmias are a major cause of sudden death in patients with structural heart disease. Current treatments focus on electrically homogenizing regions of scar contributing to ventricular arrhythmia with ablation or altering conductive properties using antiarrhythmic drugs. The high conductivity of carbon nanotubes may allow restoration of conduction in regions where impaired electrical conduction results in functional abnormalities. We propose a new concept for arrhythmia treatment using a stretchable, flexible biopatch with conductive properties to attempt to restore conduction across regions in which activation is disrupted.

Methods:

Carbon nanotube patches composed of nanofibrillated cellulose/single-walled carbon nanotube ink 3-dimensionally printed in conductive patterns onto bacterial nanocellulose were developed and evaluated for conductivity, flexibility, and mechanical properties. The patches were applied on 6 canines to epicardium before and after surgical disruption. Electroanatomic mapping was performed on normal epicardium, then repeated over surgically disrupted epicardium, and then finally with the patch applied passively.

Results:

We developed a 3-dimensional printable carbon nanotube ink complexed on bacterial nanocellulose that was (1) expressable through 3-dimensional printer nozzles, (2) electrically conductive, (3) flexible, and (4) stretchable. Six canines underwent thoracotomy, and, during epicardial ventricular pacing, mapping was performed. We demonstrated disruption of conduction after surgical incision in all 6 canines based on activation mapping. The patch resulted in restored conduction based on mapping and assessment of conduction direction and velocities in all canines.

Conclusions:

We have demonstrated 3-dimensional custom-printed electrically conductive carbon nanotube patches can be surgically manipulated to improve cardiac conduction when passively applied to surgically disrupted epicardial myocardium in canines.

Morphological development of Pellona flavipinnis post-yolk-sac larvae and juveniles (Clupeiformes: Pristigasteridae)
Authors: SEVERI WILLIAM , VERANI NELSY F.
Published: March 2019

Pristigasterids are predominantly coastal marine sardines of tropical and subtropical seas, with some species being found in fresh water. Two species of the genus Pellona, P. castelnaeana Valenciennes, 1847 and P. flavipinnis (Valenciennes, 1837), inhabit fresh waters of the neotropical region, with the latter occurring in the Pantanal of Mato Grosso, in the Paraguay River basin of central Brazil. The development of P. flavipinnis larvae and early juveniles was characterized from an ontogenic series of 27 specimens (6.3–35 mm SL), based on morphological and meristic characters. The larval and juvenile development of this freshwater sardine are typical of most clupeiforms. Exact hatching size is unknown, but it is less than 6 mm standard length (SL) and the yolk is absorbed under 10 mm. Transformation to the flexion stage occurs at about 11 mm, to the postflexion stage between 16 and 19 mm, and to the juvenile stage after 26 mm. The ventral scutes begin to form between 25 and 31 mm, with the full complement of scutes (32 to 37) formed between 32 and 35 mm. Total myomere count averages 42. As the dorsal fin and origin of the anal fin and vent migrate anteriorly, the preanal myomere count ranges from 29 in the flexion larvae to 24 in early juveniles up to 35 mm. Corresponding preanal lengths range from 85 to 61%, respectively.

Polypterus mokelembembe, a new species of bichir from the central Congo River basin (Actinopterygii: Cladistia: Polypteridae)
Authors: SCHLIEWEN ULRICH K. , SCHÄFER FRANK
Published: March 2019

Polypterus mokelembembe sp. n. is described from the central Congo River basin. It is distinguished from all other Polypterus species except P. retropinnis, P. teugelsi and P. palmas palmas by its high predorsal scale count (32–37 vs. 11–28). It differs from P. teugelsi by having 57– 60 lateral line scales (vs. 63–65), from P. palmas palmas by a single large black blotch on the pectoral-fin base (vs. numerous small spots on the posterior part of the base), and from P. retropinnis by having a wider first dorsal-fin spine (6.4–8.1 vs. 4.6–6.1 % of HL), a smaller internostril distance (11.6–13.7 vs 14.3–18.0 % of HL), and fewer pectoral-fin rays (23–29 vs. 30– 34). Inasmuch as the type series (comprising three specimens) of Polypterus retropinnis Vaillant, 1899 is of mixed composition, and includes two specimens of P. mokelembembe, a lectotype is designated for P. retropinnis and a rediagnosis for that species is provided.

Tetrabdella neotropica (Acari: Bdellidae), a new genus and species from Brazil
Authors: HERNANDES FABIO A. , FERES REINALDO J.F.
Published: March 2019

Tetrabdella neotropica Hernandes & Feres n. gen., n. sp. is the first representative of the family Bdellidae from South America. It can be distinguished from other bdellid mites by the presence of two trichobothriae on tarsi III and IV. The subfamily Spinibdellinae is herein redefined to accomodate the new genus. A key to world genera of Bdellidae is presented.
A revision of the Iblidae and the stalked barnacles (Crustacea: Cirripedia: Thoracica), including new ordinal, familial and generic taxa, and two new species from New Zealand and Tasmanian waters
Authors: BUCKERIDGE JOHN S. , NEWMAN WILLIAM A.
Published: March 2019

The discovery of two diminutive and very distinct ibliform barnacles from shallow waters off northern New Zealand and northeastern Tasmania provides an opportunity to re-evaluate the Iblidae, the most primitive of the living thoracicans. These are retained within the Superorder Thoracica, but are distinguished at ordinal level from the remainder of the Pedunculata s.l. The resultant new order, the Ibliformes nov., comprises barnacles with predominantly chitinous rather than calcareous capitular plates; two families are recognized, the Iblidae s.s., comprising two subfamilies, the Iblinae (Ibla s.s.) and the Neoiblinae nov. (Neoibla gen. nov.), and the Idioiblidae nov. comprising the Idioiblinae nov. (Idioibla gen. nov.) and the Chaetolepadinae nov. (Chaetolepas Studer, 1889 and Chitinolepas gen. nov.). The monotypic Chitinolepas further highlights the high endemism and relict nature of the New Zealand marine fauna in particular and the southern hemisphere in general. On the basis of morphology and, where possible, genetic and larval work, it is recommended that the remainder of the stalked thoracicans be divided between three new orders, the †Cyprilepadiformes, Ibliformes, Lepadiformes and Scalpelliformes.

On the morphology and classification of larval water mites (Hydrachnidia, Acari) from springs in Luxembourg
Authors: MARTIN PETER
Published: March 2019

Morphological data on the larvae of 37 species of freshwater mites (Hydrachnidia) known from springs in Luxembourg are reported. Larvae of Sperchon insignis (Walter, 1906), S. longissimus K.Viets, 1920, Lebertia holsatica K. Viets, 1920, Atractides fonticolus (K.Viets, 1920) and, with a question mark, A. pennatus (K.Viets, 1920) are described for the first time; re-descriptions are presented for Sperchon squamosus Kramer, 1879 and S. setiger Thor, 1898. Previous larval descriptions are listed and commented on for all species. Two species are recorded as new for the Luxembourgian fauna: Panisellus thienemanni (K.Viets, 1920) and Pseudofeltria scourfieldi Soar, 1904. A further taxon previously not recorded from springs in Luxembourg is described, probably Tiphys Koch, 1836 sp. An illustrated key is presented suitable for the determination of most parasitic water mite larvae attached to insect hosts from Luxembourgian springs.

Published: March 2019

Comparing the burden of dental conditions to other health outcomes provides useful insight for public policy. We aimed to estimate quality-adjusted life expectancy (QALE) loss due to dental conditions in the US adult population. Social inequalities in QALE loss by dental conditions were also examined. Data from 3 cross-sectional waves of the National Health and Nutrition Examination Survey (NHANES waves 2001 to 2002, 2003 to 2004, and 2011 to 2012) were pooled and analyzed. The average age of study participants ( n = 9,445) was 48.4 y. Disutility scores were derived from self-rated health and the numbers of physically unhealthy days, mentally unhealthy days, and days with activity limitation, employing a previously published algorithm. The associations between the disutility scores and the numbers of decayed teeth, missing teeth, and periodontitis were examined by multiple linear regression stratified by age groups (20–39, 40–59, and ≥60 y), adjusted for other covariates (age, sex, wave fixed effect, educational attainment, smoking, and diabetes). The QALE loss due to dental conditions at the age of 20 was estimated using life tables. Decayed and missing teeth, but not periodontitis, were associated with a larger disutility score. The coefficient for decayed teeth was larger among the older population, whereas that of missing teeth was smaller among them. The estimated QALE loss was 0.43 y (95% confidence interval [CI], 0.28–0.59), which reached 5.3% of QALE loss (8.15 y; 95% CI, 8.03–8.27) due to overall morbidity. There were clear social gradients in QALE loss by dental conditions across the life course, and people with high school or less education had 0.32 y larger QALE loss in total compared with people with college or more education. This study suggests that improvements in people’s dental health may yield substantial gains in population health and well-being. The necessity of more comprehensive public health strategies is highlighted.
Using the Virtual-Abstract Instructional Sequence to Support Acquisition of Algebra

Published: March 2019

Although often considered a more advanced area of mathematics, principles of algebra are taught throughout different mathematical concepts, and algebra is often considered gateway mathematical knowledge for more advanced mathematical concepts. For this reason, attention is needed toward making algebraic instruction more accessible to all types of learners, including students with disabilities who often struggle learning mathematics. Using a multiple probe across behaviors replicated across participants single-case design, this study examined whether an intervention sequence consisting of a virtual manipulative and then abstract (i.e., numerical strategies) instruction could support the acquisition of three algebraic behaviors (i.e., one-step division, two-step addition, two-step subtraction, and/or three-step addition) for four middle school students with disabilities. All four students acquired each of the linear algebra behaviors but struggled to maintain their learning once instruction was not provided prior to performance. These findings and their implications are discussed further.
Using the Short Graph Literacy Scale to Predict Precursors of Health Behavior Change
Authors: Okan Yasmina , Janssen Eva , Galesic Mirta , Waters Erika A.
Published: March 2019

Background. Visual displays can facilitate risk communication and promote better health choices. Their effectiveness in improving risk comprehension is influenced by graph literacy. However, the construct of graph literacy is still insufficiently understood, partially because existing objective measures of graph literacy are either too difficult or too long. Objectives. We constructed a new 4-item Short Graph Literacy (SGL) scale and examined how SGL scores relate to key cognitive, affective, and conative precursors of health behavior change described in common health behavior theories. Methods. We performed secondary analyses to adapt the SGL scale from an existing 13-item scale. The initial construction was based on data collected in a laboratory setting in Germany ( n = 51). The scale was then validated using data from nationally representative samples in Germany ( n = 495) and the United States ( n = 492). To examine how SGL scores relate to precursors of health behavior change, we performed secondary analyses of a third study involving a nationwide US sample with 47% participants belonging to racial/ethnic minorities and 46% with limited formal education ( n = 835). Results. Graph literacy was significantly associated with cognitive precursors in theoretically expected ways (e.g., positive associations with risk comprehension and response efficacy and a negative association with cognitive risk perception). Patterns for affective precursors generally mirrored those for cognitive precursors, although numeracy was a stronger predictor than graph literacy for some affective factors (e.g., feelings of risk). Graph literacy had predictive value for most cognitive and affective precursors beyond numeracy. In addition, graph literacy (but not numeracy) predicted key conative precursors such as defensive processing. Conclusions. Our data suggest that the SGL scale is a fast and psychometrically valid method for measuring objective graph literacy. Our findings also highlight the theoretical and practical relevance of graph literacy.
Prostatic artery embolization (PAE) in catheter-dependent patients with large prostatic (BPH) glands (>90 cc): early intervention essential
Authors: Tapping Charles R , Boardman Phil
Published: March 2019

Background

Prostate artery embolization (PAE) is safe and effective at improving lower urinary tract symptoms (LUTS) in men with benign prostatic hyperplasia (BPH).

Purpose

To assess the effectiveness of PAE on allowing successful voiding in patients with obstructive BPH (>90 cc) necessitating a urethral catheter for complete urinary retention.

Material and Methods

Ten consecutive patients with urethral catheters for obstructing BPH were included in the prospective study. Prostate arteries were embolized (Embosphere 300–500 um) and they had an attempted trial without catheter (TWOC) at two weeks and then at two-week intervals thereafter, if unsuccessful. They were clinically reviewed; an MRI was performed three and 12 months after PAE. Quality of life (QOL) questionnaires, International Prostate Symptom Score (IPSS), and International Index of Erectile Function (IIEF) were also performed.

Results

All cases were technically successful (100%). Eight patients had their catheters removed by their three-month follow-up (80%). The two cases that failed their TWOC by three months remained with a urethral catheter at 12-month follow-up. Seven of ten patients had their PAE procedure < 3 months following insertion of the urethral catheter and 100% of these had a successful TWOC before their three-month follow-up. Of the three patients that had their urethral catheter inserted > 3 months before their PAE (range 6–24 months), only 1/3 (33%) became catheter-free by 12 months after PAE. There was a dramatic reduction in LUTS and improvements in QOL indices, IPSS, and IIEF. There was no associated sexual dysfunction.

Conclusion

PAE is very successful in allowing spontaneous voiding in men with obstructing BPH requiring a urethral catheter. However, the PAE should be performed as soon as possible after the urethral catheter is inserted. Direct referral from acute urology services or emergency departments once the catheter is inserted are warranted.
Self-citations in musculoskeletal radiology: frequency and pattern analysis
Authors: Dessouky Riham , Zhang Lihua , Wadhwa Vibhor , Xi Yin , Chhabra Avneesh
Published: March 2019

Background

Author self-citation can affect quantitative aspects of scientific research. However, little is known about its prevalence in radiology literature.

Purpose

The aim of this study was to determine the frequency and factors associated with author self-citation in musculoskeletal radiology.

Material and Methods

Retrospective review of bibliographic data in musculoskeletal radiology articles of two separate journals over a 23-month period (January 2015 to November 2016) was performed to determine frequency of author self-citations. Other data included article type, topic, title length, author order, affiliation, and geographic location.

Results

One-third of all included articles had author self-citations with a mean and median of 2.8 and 2 citations per article. Case reports contained up to 52.4% self-citations (mean = 11.2%, 95% CI = 5.9–16.5). Larger frequencies of self-citations were found among first and second authors and university-affiliated authors. The United States was the most frequent country to produce publications but did not have the highest percentage of self-citations.

Conclusion

Self-citations in musculoskeletal radiology is no different than other medical fields. It does not currently seem to pose a threat on the integrity of scientific research and is usually needed to expand on previous knowledge. Nevertheless, authors and journals should be aware of implications of abusing such practice on future medical research.
