Good CoP: what makes a community of practice successful?
Authors: Baker Anthony Thomas , Beames Stephanie 
Published: June 2016

<p>We have established a community of practice focussed on student learning in first-year science. It is recognised that transition, whether from school to university or other possible transitions, is an issue that is a concern for the entire sector, and this is acknowledged both at Faculty and University level. One of the factors to which we attribute the success of this CoP is that we are working within the context of a well-established set of transition pedagogies which have been strongly promoted and supported within UTS. There is also an internal grants scheme that provides small amounts of funding for initiatives aimed at improving transition and engagement as part of the widening participation strategy. Another factor for the success of this group is the leadership and active engagement of a senior staff member. This CoP has not evolved organically as a grass-roots group, nor has it been commissioned from on-high. The Faculty of Science has also recently appointed an academic developer to support course renewal and the mapping of graduate attributes, and this role includes the support of initiatives like setting up CoPs.</p>
Online lecture recordings and lecture attendance: Investigating student preferences in a large first year psychology course
Authors: Yeung Alexandra , Raju Sadhana , Sharma Manjula D. 
Published: June 2016

<p>While blended learning has been around for sometime, the interplay between lecture recordings, lecture attendance and grades needs further examination particularly for large cohorts of over 1000 students in 500 seat lecture theatres. This paper reports on such an investigation with a cohort of 1450 first year psychology students’ who indicated whether they frequently attended lectures or not. The division helped ascertain differences and similarities in preferences for utilising online recordings. Overall, non-frequent attendees were more likely not to use lecture recordings (48.1%) to make up a missed lecture than frequent attendees (34.3%). Surprisingly, in the last week of semester, 29% of students reported not yet accessing lecture recordings. Students had the intention to use lecture recordings as they envisaged these to be helpful for learning and commented that they would be adversely affected if recordings were not available. In fact, students are passionate about lecture recordings. Analytics show that after lecture 7, each lecture recording attracted 600 or less unique visits (hits) supporting the finding that most students make strategic use of learning resources available within the blended learning environment.</p>

Published: June 2016

Factitious medical disorders with the well-known eponym of Munchausen’s syndrome represent a challenge in both diagnosis and management for the clinician. Here, we report a case of “Biochemical Munchausen’s” in a 36-year-old female, characterised by recurrent and multiple presentations with symptomatic hypokalaemia, supraventricular tachycardia and lactic acidosis that required the use of biochemical laboratory expertise and liquid chromatography/mass spectrophotometry to unravel and break the cycle of costly investigations and hopefully contain the risk of potential harm. We also highlight the evolution of various stages of generating factitious illness in this 36-year-old female with the crucial breakthrough being made only by proof of the biochemical exposure through the close collaboration of biochemist and clinicians.
Surgical Management of Gout in the Foot and Ankle
Authors: Poratt Daniel , Rome Keith 
Published: June 2016

Background: The surgical management of tophaceous gout has been well documented in the literature, including its effect on foot pain and disability. To date, there have been no systematic reviews assessing the quality of the literature relating to the operative management of tophaceous gout and the outcomes in the foot and ankle.Methods: The following electronic databases were searched (1980–2014): Allied and Complementary Medicine, Cumulative Index to Nursing and Allied Health Literature, MEDLINE, Scopus, and the Cochrane Library. The articles identified were published in English and included adult participants (age ≥18 years) with diagnosed gout and surgical intervention to the foot and ankle. The Downs and Black Quality Index was modified to assess the quality of the articles being reviewed.Results: Six articles were reviewed and were of moderate quality (mean quality score of 71%). Surgical management was conducted on men (88%) with a mean age of 52 years. There was wide variation in the types of surgical procedures performed, with 28% of studies reporting surgery to the first metatarsophalangeal joint. Most studies were retrospective. A wide range of outcome measures were reported: foot pain, function, preoperative and postoperative activity levels, monitoring of uric acid levels, and patient satisfaction after surgery.Conclusions: The review demonstrated a limited number of good-quality studies. Several surgical procedures for the foot and ankle in people with chronic tophaceous gout were reported. Future studies should include prospective observational studies using validated and reliable patient-reported outcome measures.
Radiographic Measurements of the Affected and Unaffected Feet in Patients with Unilateral Hallux Limitus
Authors: Knox Andrew F. , Bryant Alan R. 
Published: June 2016

Background: Controversy exists regarding the structural and functional causes of hallux limitus, including metatarsus primus elevatus, a long first metatarsal, first-ray hypermobility, the shape of the first metatarsal head, and the presence of hallux interphalangeus. Some articles have reported on the radiographic evaluation of these measurements in feet affected by hallux limitus, but no study has directly compared the affected and unaffected feet in patients with unilateral hallux limitus. This case-control pilot study aimed to establish whether any such differences exist.Methods: Dorsoplantar and lateral weightbearing radiographs of both feet in 30 patients with unilateral hallux limitus were assessed for grade of disease, lateral intermetatarsal angle, metatarsal protrusion distance, plantar gapping at the first metatarsocuneiform joint, metatarsal head shape, and hallux abductus interphalangeus angle. Data analysis was performed using a statistical software program.Results: Mean radiographic measurements for affected and unaffected feet demonstrated that metatarsus primus elevatus, a short first metatarsal, first-ray hypermobility, a flat metatarsal head shape, and hallux interphalangeus were prevalent in both feet. There was no statistically significant difference between feet for any of the radiographic parameters measured (Mann-Whitney U tests, independent-samples t tests, and Pearson χ2 tests: P &gt; .05).Conclusions: No significant differences exist in the presence of the structural risk factors examined between affected and unaffected feet in patients with unilateral hallux limitus. The influence of other intrinsic factors, including footedness and family history, should be investigated further.

Published: June 2016

Background: People with Down syndrome present skeletal abnormalities in their feet that can be analyzed by commonly used gold standard indices (the Hernández-Corvo index, the Chippaux-Smirak index, the Staheli arch index, and the Clarke angle) based on footprint measurements. The use of Photoshop CS5 software (Adobe Systems Software Ireland Ltd, Dublin, Ireland) to measure footprints has been validated in the general population. The present study aimed to assess the reliability and validity of this footprint assessment technique in the population with Down syndrome.Methods: Using optical podography and photography, 44 footprints from 22 patients with Down syndrome (11 men [mean ± SD age, 23.82 ± 3.12 years] and 11 women [mean ± SD age, 24.82 ± 6.81 years]) were recorded in a static bipedal standing position. A blinded observer performed the measurements using a validated manual method three times during the 4-month study, with 2 months between measurements. Test-retest was used to check the reliability of the Photoshop CS5 software measurements. Validity and reliability were obtained by intraclass correlation coefficient (ICC).Results: The reliability test for all of the indices showed very good values for the Photoshop CS5 method (ICC, 0.982–0.995). Validity testing also found no differences between the techniques (ICC, 0.988–0.999).Conclusions: The Photoshop CS5 software method is reliable and valid for the study of footprints in young people with Down syndrome.
Optimum reaction conditions for lead zirconate titanate thick film deposition by ultrasound-assisted hydrothermal method
Authors: Saigusa Katsuhiro , Morita Takeshi 
Published: June 2016

Abstract
A hydrothermal method can be used to deposit lead zirconate titanate (PZT) films and has several advantages, such as a relatively low reaction temperature and high crystal quality. We developed an ultrasound-assisted hydrothermal method to promote the hydrothermal reactions, which is effective for thick-PZT-film deposition. The first ultrasound-assisted hydrothermal method we developed can synthesize a 7.5 µm PZT film on a titanium substrate. However, for a much thicker film, repeated depositions were required, and the optimum precursor solution for the first deposition was not suitable for repeated depositions. In this study, we attempted to find the optimum precursor solution for depositing a film of sufficient thickness by repeated depositions. As a result, we were able to synthesize a 23.6 µm PZT film on second deposition by changing the ratio of zirconium to titanium ions in the precursor solutions. In addition, a transverse effect transducer was fabricated under optimum conditions and its vibration properties were evaluated.
A systematic review of reviews on the prevalence of anxiety disorders in adult populations

Published: June 2016

AbstractBackgroundA fragmented research field exists on the prevalence of anxiety disorders. Here, we present the results of a systematic review of reviews on this topic. We included the highest quality studies to inform practice and policy on this issue.MethodUsing PRISMA methodology, extensive electronic and manual citation searches were performed to identify relevant reviews. Screening, data extraction, and quality assessment were undertaken by two reviewers. Inclusion criteria consisted of systematic reviews or meta‐analyses on the prevalence of anxiety disorders that fulfilled at least half of the AMSTAR quality criteria.ResultsWe identified a total of 48 reviews and described the prevalence of anxiety across population subgroups and settings, as reported by these studies. Despite the high heterogeneity of prevalence estimates across primary studies, there was emerging and compelling evidence of substantial prevalence of anxiety disorders generally (3.8–25%), and particularly in women (5.2–8.7%); young adults (2.5–9.1%); people with chronic diseases (1.4–70%); and individuals from Euro/Anglo cultures (3.8–10.4%) versus individuals from Indo/Asian (2.8%), African (4.4%), Central/Eastern European (3.2%), North African/Middle Eastern (4.9%), and Ibero/Latin cultures (6.2%).ConclusionsThe prevalence of anxiety disorders is high in population subgroups across the globe. Recent research has expanded its focus to Asian countries, an increasingly greater number of physical and psychiatric conditions, and traumatic events associated with anxiety. Further research on illness trajectories and anxiety levels pre‐ and post‐treatment is needed. Few studies have been conducted in developing and under‐developed parts of the world and have little representation in the global literature.

AbstractWe aimed to investigate the incidence and long‐term outcome of moyamoya syndrome in pediatric patients with primary brain tumors after receiving cranial radiotherapy (RT) in a single institute in Taiwan. The complete medical records, medical images, and RT notes of 391 pediatric patients with primary brain tumors treated with cranial RT between January 1975 and December 2005 in Taipei Veterans General Hospital (TVGH), Taiwan, were entered into an electronic registry and reviewed. Eight (2%) cases of post‐RT moyamoya syndrome were identified in the sample of 391 patients. The median latency was 3 years post‐RT. Among the eight patients, three had craniopharyngioma, two had optic glioma, two had medulloblastoma, and one had a suprasellar astrocytoma. The prescribed physical doses of RT were in the range of 40–54 Gy. The incidence was highest in those with optic glioma (0.039/person‐year), followed by craniopharyngioma (0.013/person‐year), astrocytoma (0.003/person‐year), and medulloblastoma (0.002/person‐year). No patients died of vasculopathy. No difference in crude incidence was found between our results and those of other series. The incidence of moyamoya syndrome was diagnosis dependent, with the highest incidence among patients with optic glioma. No regional difference in incidence was found. Long‐term, stable neurological function may be achieved following timely surgical intervention.
Spatial scale‐dependent vertical zonation of coral reef community structure in French Polynesia
Authors: Edmunds Peter J. , Leichter James J. 
Published: June 2016

AbstractWe tested for depth‐dependent vertical zonation in coral reef community structure with surveys conducted in 2013 at 10 m and 27 m depth off the islands of Moorea, Tahiti, Maiao, and Tetiaroa, which are distributed over ~3500 km2 of the tropical south Pacific. Benthic communities were censused using photoquadrats to obtain percentage cover, first by functional groups (scleractinians, macroalgae, and crustose coralline algae, algal turf, and bare space combined [CTB]), and second by genus for scleractinians and Millepora. Virtually every aspect of community structure differed between the two depths, but the effects were dependent on spatial scale of investigation. Interactive effects of islands and depths determined the abundance of functional groups, as well as seven of eight common coral genera. On the two islands at which two sites were censused, the abundance of functional groups also differed between sites, and was affected by depth × site interactions. The spatially variable effects of depth on community structure underscores the importance of context‐specific synergy between biotic and abiotic factors in driving these patterns. Spatial scale‐dependent vertical zonation also shows the potential for these effects to be modulated by the changes that have affected coral community structure on contemporary reefs over the last few decades.

Published: June 2016

ObjectiveThe objective of this study was to ascertain if cognition helps to predict functional outcome in older comorbid stroke patients with severe loss of independence.DesignThis is a cross‐sectional study.SubjectsThe subjects of this study are patients who have suffered a stroke and who rehabilitated in the nursing homes' rehabilitation units and patients (n = 160) (mean age: 77; SD: 9.5) with a mean Barthel Index of 11.02.MethodDemographic, illness‐related, functional and cognitive data were selected at baseline.Main Assessment MeasuresFunctional abilities were tested using the Barthel Index. Cognitive functions were assessed using a wide variety of neuropsychological tests.ResultsPatients faced cognitive impairments especially in executive functioning and memory. Stepwise linear regression analysis shows that executive functioning (p = 0.050) and memory (p = 0.000; confidence interval −1.255, −0.403) are significantly associated with functional outcome.ConclusionFrom a clinical point of view, we suggest combining physical and cognitive training from the very early phase of recovery.
Protein engineering of Saccharomyces cerevisiae transporter Pdr5p identifies key residues that impact Fusarium mycotoxin export and resistance to inhibition

Published: June 2016

AbstractCereal infection by the broad host range fungal pathogen Fusarium graminearum is a significant global agricultural and food safety issue due to the deposition of mycotoxins within infected grains. Methods to study the intracellular effects of mycotoxins often use the baker's yeast model system (Saccharomyces cerevisiae); however, this organism has an efficient drug export network known as the pleiotropic drug resistance (PDR) network, which consists of a family of multidrug exporters. This study describes the first study that has evaluated the potential involvement of all known or putative ATP‐binding cassette (ABC) transporters from the PDR network in exporting the F. graminearum trichothecene mycotoxins deoxynivalenol (DON) and 15‐acetyl‐deoxynivalenol (15A‐DON) from living yeast cells. We found that Pdr5p appears to be the only transporter from the PDR network capable of exporting these mycotoxins. We engineered mutants of Pdr5p at two sites previously identified as important in determining substrate specificity and inhibitor susceptibility. These results indicate that it is possible to alter inhibitor insensitivity while maintaining the ability of Pdr5p to export the mycotoxins DON and 15A‐DON, which may enable the development of resistance strategies to generate more Fusarium‐tolerant crop plants.
A S‐Arylation of 2‐Mercaptoazoles with Diaryliodonium Triflates under Metal‐Free and Base‐Free Conditions
Authors: Zhang Bianxiang , Kang Yongqiang , Yang Lihua , Chen Xia 
Published: June 2016

AbstractHeterocyclic aryl sulfides have been widely studied as a monomer or an intermediate for drug synthesis in the field of medicine and materials. The common synthetic processes for preparing aryl sulfides involve transition metals and strong bases. Here, we report a synthetic method for heterocyclic arylsulfides is accomplished by S‐arylation of 2‐mercapto‐substituted aromatic heterocycles with diaryliodonium triflates in high yields. The procedure involves only mixing 2‐mercapto‐aromatic heterocycles and diaryliodonium triflates in DMF at 130 ºC for 24 h under air atmosphere. The most prominent advantage of this method is that all of the ligands, catalysts, bases and any additives are unnecessary. A highly efficient green approach to heterocyclic aryl sulfides was described and the reaction mechanism was discussed.

Published: June 2016

Purpose Traumatic bowel and mesenteric injury (TBMI), although an uncommon entity, can be lethal if not detected and treated in a timely manner. The purpose of our study was to evaluate the diagnostic accuracy of 64-slice multidetector computed tomography (MDCT) for the detection of TBMI in patients at our level 1 trauma centre. Methods We used our hospital's trauma registry to identify patients with a diagnosis of TBMI from January 1, 2006, to June 30, 2013. Only patients who had a 64-slice MDCT scan at presentation and subsequently underwent laparotomy or laparoscopy were included in the study cohort. Using the surgical findings as the gold standard, the accuracy of prospective radiology reports was analyzed. Results Of the 4781 trauma patients who presented to our institution, 44 (0.92%) had surgically proven TBMI. Twenty-two of 44 were excluded as they did not have MDCT before surgery. The study cohort consisted of 14 males and 8 females with a median age of 41.5 years and a median injury severity score of 27. In total 17 of 22 had blunt trauma and 5 of 22 had penetrating injury. A correct preoperative imaging diagnosis of TBMI was made in 14 of 22 of patients. The overall sensitivity of the radiology reports was 63.6% (95% confidence interval [CI]: 41%-82%), specificity was 79.6% (95% CI: 67%-89%), PPV was 53.9% (95% CI: 33%-73%), and the NPV was 85.5% (95% CI: 73%-94%). Accuracy was calculated at 75.3%. However, only 59% (10 of 17) of patients with blunt injury had a correct preoperative diagnosis. Review of the findings demonstrated that majority of patients with missed blunt TBMI (5 of 7) demonstrated only indirect signs of injury. Conclusion The detection of TBMI in trauma patients on 64-slice MDCT can be improved, especially in patients presenting with blunt injury. Missed cases in this population occurred because the possibility of TBMI was not considered despite the presence of indirect imaging signs. The prospective diagnosis of TBMI remains challenging despite advances in CT technology and widespread use of 64-slice MDCT.

AbstractObjectiveTo evaluate the cumulative recurrence rates of ovarian endometrioma among patients using a levonorgestrel‐releasing intrauterine system (LNG‐IUS) after conservative laparoscopic surgery.MethodsA retrospective review was conducted of premenopausal women who underwent conservative laparoscopic surgery for ovarian endometrioma and subsequent treatment with LNG‐IUS at two gynecologic surgery centers in South Korea between January 1, 2007, and September 30, 2014. Eligible patients had no residual ovarian lesions before LNG‐IUS insertion, underwent insertion within 12 months of primary surgery, and were followed up for at least 6 months afterwards. Recurrence was defined as a cystic mass (≥ 2 cm in diameter) detected by transvaginal ultrasonography.ResultsOverall, 61 patients were included. The mean duration of follow‐up was 42.9 ± 22.0 months (range 8–98). Recurrence of ovarian endometrioma was detected among 7 (11%) of the patients. On Kaplan–Meier analysis, the cumulative recurrence rates were 4.0%, 6.3%, and 25.5% at 24, 36, and 60 months after surgery, respectively. In multivariate analysis, nulliparity at surgery was the only risk factor for recurrence (hazard ratio 5.892, 95% confidence interval 1.139–30.484; P = 0.034).ConclusionLong‐term maintenance therapy with LNG‐IUS after conservative surgery might be a treatment option to consider to prevent ovarian endometrioma recurrence among premenopausal women.
