Unique or ubiquitous: information literacy instruction outside academia
Authors: Matteson Miriam L. , Gersch Beate 
Published: April 2019

Purpose
The purpose of this paper is to investigate how US public libraries offer information literacy (IL) instruction to their patrons.

Design/methodology/approach
The study is a content analysis of eight library websites to determine passive IL instruction and active literacy instruction.

Findings
Library web guides offer passive IL instruction by highlighting resources patrons may wish to access to resolve information inquiries. Further, the authors found that a little less than 50 per cent of library programming offers some IL instruction, the majority of which relates to helping patrons learn to use tools to create information products.

Originality/value
IL is the ability to recognize the need for information, to effectively find information to meet that need and to use information for some purpose or goal. Academic, school and public libraries believe that understanding and using information critically and effectively bring gains to an individual and to society. However, they diverge in how and why they engage in IL instruction. The authors’ findings suggest that less than half of the libraries surveyed are providing active IL instruction, despite the recognition of the benefits IL provides.

Authors: Blasco-Lopez Francisca , Recuero Virto Nuria , Aldas Manzano Joaquin , Cruz Delgado Daniela 
Published: April 2019

Purpose
The purpose of this paper is to examine the role that Facebook Fan Pages (FFPs) play in the generation of visit intention. The study has three objectives: first, to examine the effects of museum-generated content (MGC) on perceived information quality and perceived customer service and perceived information quality and perceived customer service on visit intention and, second, to test the model with two samples to make comparisons that provide useful insights.

Design/methodology/approach
Data were collected through an online survey that achieved 308 valid responses. A multi-group analysis was conducted to compare the results from two groups: users of the Frida Kahlo museum and Anahuacalli museum FFPs.

Findings
The results reveal that there are significant differences between the two samples regarding the direct effects of perceived information quality on visit intention and perceived customer service on visit intention. The authors also noted a slight difference between the two museums’ FFPs in the relationship between MGC and perceived information quality.

Research limitations/implications
Further research is needed to examine other FFP factors that influence visit intention to clarify the results obtained from the two samples and to analyse the proposed model in other settings. This research contributes to the literature concerning the impact of online platforms on visit intention.

Originality/value
The findings provide useful insights for managers as to how to increase their FFP followers’ intention to visit their establishments.

Published: April 2019

ObjectivesTo compare existing algorithms for classifying screening vs diagnostic colonoscopies and to quantify the increase in screening colonoscopy rates when Medicare began reimbursement in 2001 and when the Affordable Care Act (ACA) eliminated cost‐sharing.Data SourcesTwenty percent random sample of fee‐for‐service (FFS) Medicare claims, 2000‐2012.Study DesignUsing recent administrative codes as tarnished gold standards, we examined the sensitivity and specificity of five published algorithms for classifying colonoscopies and calculated annual screening colonoscopy rates. We estimated the change in rates after Medicare began reimbursement and used difference‐in‐differences analysis to estimate the effects of eliminating cost‐sharing by comparing states with and without a mandate to cover screening colonoscopy prior to the ACA.FindingsModel‐based algorithms have higher sensitivity (0.53‐0.99) than expert‐based algorithms (0.35‐0.39), but lower specificity (0.43‐0.65 vs 0.79‐0.88). All algorithms detected increases in screening from both Medicare's reimbursement change (range: 24‐93/10 000) and the 2011 cost‐sharing change (range: 1.1‐34/10 000). Difference‐in‐difference estimates of the ACA's effect varied from 51 to 155 tests per 10 000 depending on the algorithm.ConclusionsScreening colonoscopy rates increased after eliminating cost‐sharing in 2011, but the increase's size varied depending on the algorithm used to classify the indication. Improvements are needed in Medicare coding for screening.

Published: April 2019

AbstractPsychostimulant use is associated with increased stroke risk. To determine the proportion of psychostimulant users among fatal strokes in young adults (15–44 years), all cases were retrieved from the National Coronial Information System (1/1/2009–31/12/2016). A total of 279 cases were identified: hemorrhagic (259), ischemic (8), thrombotic (8), and mycotic (4). Fifty (17.9%) were identified as psychostimulant users. Psychostimulants in blood were detected in 37/45 where toxicology was available, predominantly methamphetamine (32/45). Hemorrhagic strokes in the psychostimulant group were more likely to be intraparenchymal (OR 2.33). Psychostimulant users were less likely to be obese (OR 0.31), but more likely to have a history of tobacco use (OR 2.64). No psychostimulant user had a previous stroke history, was gravid/postpartum, or diagnosed with cerebral vasculitis or endocarditis. The work illustrates the substantial role of psychostimulant use in fatal strokes among young adults. In cases of hemorrhagic stroke among young adults, psychostimulant use should be considered.

Published: April 2019

AbstractCardiac abnormalities, including left ventricular hypertrophy and systolic dysfunction, are frequently observed among patients with CKD, including kidney transplant recipients; they are closely linked to cardiovascular disease and mortality. Although several studies have been performed for elucidating changes and mechanisms of cardiac abnormalities after kidney transplantation, details remain unclear. This study included 43 consecutive patients who underwent HD and received kidney transplantation between 2008 and 2012 at our institution. All subjects underwent echocardiography before and 1 year after kidney transplantation. One year after kidney transplantation, left ventricular mass index, cardiac chamber sizes, BP, and the number of antihypertensive agents were reduced. Although the percentage of patients with concentric hypertrophy did not change, the percentage of those with eccentric hypertrophy significantly decreased after kidney transplantation. Volume reduction due to the recovery of kidney function may be primarily attributed to the improvement of cardiac abnormalities, including left ventricular hypertrophy.

AbstractBackgroundThis study examined whether resting heart rate (RHR) was associated with metabolic syndrome (MetS) and the 10‐year predicted risk of cardiovascular disease in a Chinese population.MethodsThe associations of RHR with MetS and 10‐year risk of atherosclerotic cardiovascular diseases (ASCVD) was examined in a cross‐sectional study conducted in Shanghai, China (n = 9486).ResultsCompared with individuals in the lowest RHR quintile (≤71 b.p.m.), those in the highest quintile (≥91 b.p.m.) had a higher prevalence of MetS (21.2% vs 32.6%, respectively; P < 0.001). Logistic regression analyses showed that the multivariate‐adjusted odds ratio (OR) and 95% confidence interval (CI) for MetS was 1.13 (1.08‐1.18) for each 10‐b.p.m. increment of RHR (P < 0.0001). Furthermore, RHR was strongly associated with the prevalence of hypertension, high blood glucose, and dyslipidemia, but not with central obesity. A stronger association of RHR with MetS was observed among individuals aged <65 years, male, with a body mass index <24 kg/m2, without diabetes, hypertension, abnormal lipids, and insulin resistance than among their counterparts (P < 0.05 for all). A significantly higher 10‐year risk for ASCVD was observed with each 10‐b.p.m. increment in RHR in both men and women (ORs [95% CIs] 1.20 [1.07‐1.33] and 1.28 [1.17‐1.39], respectively; Ptrend = 0.002 and < 0.0001, respectively).ConclusionsIn this study, RHR was associated with a higher prevalence of MetS and elevated 10‐year predicted risk of ASCVD in both Chinese men and women. Whether RHR may serve as an indicator for MetS among relatively healthy individuals requires further investigation.
What does a zero mean? Understanding false, random and structural zeros in ecology

Published: April 2019

Abstract

Zeros (i.e. events that do not happen) are the source of two common phenomena in count data: overdispersion and zero‐inflation. Zeros have multiple origins in a dataset: false zeros occur due to errors in the experimental design or the observer; structural zeros are related to the ecological or evolutionary restrictions of the system under study; and random zeros are the result of the sampling variability. Identifying the type of zeros and their relation with overdispersion and/or zero inflation is key to select the most appropriate statistical model.

Here we review the different modelling options in relation to the presence of overdispersion and zero inflation, tested through the dispersion and zero inflation indices. We then examine the theory of the zero‐inflated (ZI) models and the use of the score tests to assess overdispersion and zero inflation over a model.

In order to choose an adequate model when analysing count data we suggest the following protocol: Step 1) classify the zeros and minimize the presence of false zeros; Step 2) identify suitable covariates; Step 3) test the data for overdispersion and zero‐inflation and Step 4) choose the most adequate model based on the results of step 3 and use score tests to determine whether more complex models should be implemented.

We applied the recommended protocol on a real dataset on plant–herbivore interactions to evaluate the suitability of six different models (Poisson, NB and their zero‐inflated versions—ZIP, ZINB). Our data were overdispersed and zero‐inflated, and the ZINB was the model with the best fit, as predicted.

Ignoring overdispersion and/or zero inflation during data analyses caused biased estimates of the statistical parameters and serious errors in the interpretation of the results. Our results are a clear example on how the conclusions of an ecological hypothesis can change depending on the model applied. Understanding how zeros arise in count data, for example identifying the potential sources of structural zeros, is essential to select the best statistical design. A good model not only fits the data correctly but also takes into account the idiosyncrasies of the biological system.

Published: April 2019

AbstractObjectiveLevels of fibroblast growth factor 23 (FGF23) have been positively associated with measures of adiposity, cardiovascular disease and mortality. It is unclear whether the relationship of FGF23 with cardiovascular disease and mortality is confounded by obesity. We aimed to determine whether FGF23 concentrations decline following a reduction in adiposity after sleeve gastrectomy (SG).DesignThe effect of SG on FGF23 was evaluated in 22 obese adults (59% male) with type 2 diabetes. Fat mass, weight, BMI, plasma intact FGF23, parathyroid hormone (PTH) and leptin were determined at baseline and at 12 months following SG.ResultsAt baseline, median (IQR) age was 51 (43‐54) years, fat mass 47.8 (41.0‐59.4) kg, BMI 40.9 (36.9‐46.9) kg/m2 and FGF23 66.2 (55.3‐82.9) pg/mL. Significant changes in median BMI (−10.8 kg/m2, 95% CI: −12.9 to −7.2, P < 0.0001), fat mass (−20.0 kg, 95% CI: −26.7 to −12.4, P < 0.0001) and weight (−34.7 kg, 95% CI −40.0 to −23.1, P < 0.0001) were observed after SG. FGF23 (−12.4 pg/mL, 95% CI: −19.5 to 2.0, P = 0.005), PTH (−1.1 pmol/L, 95% CI: −1.7 to 0.2, P = 0.009) and leptin (−1687 pg/mL, 95% CI −4524 to −563, P = 0.01) declined following SG. Change in FGF23 was not significantly associated with change in measures of adiposity, PTH or leptin.ConclusionsFGF23 concentrations decline in the setting of significant weight loss following SG, implying that increased FGF23 concentrations are a downstream consequence of obesity, which may confound its association with cardiometabolic dysfunction. Mediators of the relationship between adiposity and FGF23 require further elucidation.
Urothelial carcinoma arising from the transplanted kidney: A single‐center experience and literature review
Authors: Bellini Maria Irene , Gopal Jeevan Prakash , Hill Peter , Nicol David , Gibbons Norma 
Published: April 2019

AbstractUrothelial carcinoma (UC) is a malignancy predominantly arising in the bladder. Upper tract UC (UUC) is uncommon, accounting only for 5‐10% of the cases. High incidence of neoplasms is associated with immunosuppressive therapy; thus, UCs of the transplanted grafts often lead to a more aggressive treatment, in order to withdraw completely the immunosuppression. It significantly affects the patient quality of life, meaning return to dialysis, along with the worse life expectancy. We present our single‐institution experience of this rare malignancy in two mid‐age kidney transplant recipients, with UCs successfully treated with radical nephroureterectomy: G3 pT3 N0 + G3 pT1 N0 in the first patient and G3 pT2 N0 in the second one. We also review the previous literature focusing on stage of presentation and treatment for the affected kidney transplant patients.
Giant clams discriminate threats along a risk gradient and display varying habituation rates to different stimuli

Published: April 2019

AbstractIt is often beneficial for animals to discriminate between different threats and to habituate to repeated exposures of benign stimuli. While much is known about risk perception in vertebrates and some invertebrates, risk perception in marine invertebrates is less extensively studied. One method to study risk perception is to habituate animals to a series of exposures to one stimulus, and then present a novel stimulus to test if it transfers habituation. Transfer of habituation is seen as a continued decrease in response while lack of transfer is seen either by having a similar or greater magnitude response. We asked whether giant clams (Tridacna maxima) discriminate between biologically relevant types of threats along a risk gradient. Giant clams retract their mantle and close their shell upon detecting a threat. While closed, they neither feed nor photosynthesize, and prior work has shown that the cost of being closed increases as the duration of their response increases. We recorded a clam's latency to emerge after simulated threats chosen to represent a risk gradient: exposure to a small shading event, a medium shading event, a large shading event (chosen to simulate fish swimming above them), tapping on their shell and touching their mantle (chosen to simulate different degrees of direct attack). Although these stimuli are initially perceived as threatening, we expected clams to habituate to them because they are ultimately non‐damaging and it would be costly for clams to remain closed for extended periods of time when there is no threat present. Clams had different initial latencies to emerge and different habituation rates to these treatments, and they did not transfer habituation to higher risk stimuli and to some lower risk stimuli. These results suggest that clams discriminated between these stimuli along a risk gradient and the lack of habituation transfer shows that the new stimulus was perceived as a potential threat. This study demonstrates that sessile bivalves can discern between levels of predatory threat. These photosynthetic clams may benefit from being able to categorize predator cues for efficient energy allocation.

SummaryXinjiang is a high‐risk area for celiac disease (CD) regardless of genetic or environmental factors. However, no case has been reported yet in people living in Xinjiang. This study aims to explore the potential connection between diet and occurrence of CD in the Xinjiang population. To this end, the levels of T‐cell stimulatory epitopes in 164 accessions of Xinjiang wheat were tested by using Western blot with monoclonal antibodies against α‐gliadin epitopes Glia‐α9 and Glia‐α20. Three wheat varieties with remarkably low amounts of T‐cell stimulatory epitopes were obtained. Western blot and R5 competitive ELISA were performed for the assessment of potential toxicity related to CD of naan. Results showed a reduction of gluten toxicity after wheat flour was processed into naan, suggesting it may have the potential to help to reduce the risk of CD for the genetically predisposed individuals.

Authors: Crivelli Joseph J , Alhalabi Feras , Zimmern Philippe E 
Published: April 2019

ObjectiveTo evaluate the long‐term efficacy of electrofulguration in women with recurrent urinary tract infections.MethodsAfter institutional review board approval, a retrospective study of women who underwent electrofulguration alone was carried out. All patients had recurrent urinary tract infections defined as three or more urinary tract infections/year, and a preoperative office cystoscopy showing inflammatory lesions, categorized by location: urethra, bladder neck, trigone and beyond the trigone. All lesions were cauterized during outpatient electrofulguration under anesthesia. On 6‐month postoperative office cystoscopy, endoscopic success was defined as resolution of all lesions previously seen and no new lesions. The primary outcome was urinary tract infections/year, with urinary tract infection defined as antibiotic treatment for urinary tract infection‐like symptoms and/or for positive urine culture. Clinical cure was defined as no further urinary tract infections, clinical improvement as less than three urinary tract infections/year, and clinical failure as three or more urinary tract infections/year.ResultsOf 95 women who met the study criteria between 2004 and 2016, 62 (65%) were endoscopically successful, and 33 (35%) were endoscopic failures based on postoperative cystoscopy. Among all patients, over a median follow‐up period of 4.9 years, the median number of urinary tract infections/year was 0.8. Endoscopically successful patients had fewer urinary tract infections/year compared with endoscopic failures (0.6 vs 0.9, P = 0.03). Clinically, 14 (15%) patients were cured, 69 (73%) were improved and 12 (13%) failed. Compared with clinically improved patients, clinical failures were more likely to have infections with multiple organisms (92% vs 35%, P < 0.001) and highly resistant organisms (92% vs 23%, P < 0.001).ConclusionsIn our experience, nearly two‐thirds of women with recurrent urinary tract infection can be successfully treated with electrofulguration, and >80% experience long‐term clinical cure or improvement in urinary tract infections.
Impact of multiple co‐occurring emotional and behavioural conditions on children with autism and their families

Published: April 2019

AbstractBackgroundComorbid conditions are very common in children and adults with autism spectrum disorder (ASD) and can affect school performance, adaptive skills and peer relationships. Comorbid conditions place strain on the family as well as the individual with ASD. This project aimed to determine the affect of comorbid conditions over and above child and family characteristics.MethodsThe present authors examined 3,055 cases of children with ASD who had varying numbers of comorbid conditions (i.e., ADHD, depression, anxiety or behaviour problems).ResultsMultiple comorbid conditions did have a unique impact on difficulties accessing services. A greater number of comorbid conditions impacted daily activity participation, but not a family's receipt of mental health care or respite, work changes or number of weekly hours dedicated to caring for a child with ASD.ConclusionsFamilies, practitioners, paraprofessionals and educators of children with autism should address comorbid conditions to ensure both child and family well‐being.
