Harmonization of microbiology processes and standards: work in progress
Authors: Samuel Linoj P. 
Published: July 2018

Abstract
Clinical microbiology is a highly challenging technical discipline, which makes it difficult to harmonize processes and protocols. In addition, the lack of scientific consensus on some diagnostic algorithms and the need to address the diverse needs of different patient populations contribute to the lack of interlaboratory consistency. Laboratories utilize a number of measures and metrics, but the lack of standardized approaches and data collection means that they cannot effectively evaluate their performance against their peers. Coordinated efforts are required to develop tools that can be used across laboratories regardless of size or complexity.
Uncertainty in measurement and total error: different roads to the same quality destination?
Authors: Farrance Ian , Badrick Tony , Frenkel Robert 
Published: July 2018

Abstract
The debate comparing the benefits of measurement uncertainty (uncertainty in measurement, MU) with total error (TE) for the assessment of laboratory performance continues. The summary recently provided in this journal by members of the Task and Finish Group on Total Error (TFG-TE) of the EFLM put the arguments into clear perspective. Even though there is generally strong support for TE in many laboratories, some of the arguments proposed for its on-going support require further comment. In a recent opinion which focused directly on the TFG-TE summary, several potentially confusing statements regarding ISO15189 and the Evaluation of measurement data – Guide to the expression of uncertainty in measurement (GUM) were again promulgated to promote TE methods for assessing uncertainty in laboratory measurement. In this opinion, we present an alternative view of the key issues and outline our views with regard to the relationship between ISO15189, uncertainty in measurement and the GUM.
Flow-induced failure mechanisms of copper pipe in potable water systems
Authors: Roy Siddhartha , Coyne Jeffrey M. , Novak Julia A. , Edwards Marc A. 
Published: July 2018

AbstractErosion or velocity-induced copper pipe corrosion is a significant problem in potable water systems, especially hot water recirculation systems. The little scientific work done in freshwater has not always been able to scientifically isolate the key factors causing these failures; in fact, most existing recommendations rely on anecdotal and/or experiential knowledge from forensic analysis of field failures, which are not confirmed by complementary laboratory research. Consequently, this comprehensive review summarizes prior observations that include mechanical and electrochemical attack induced by water chemistry, temperature, velocity, hydrodynamic conditions, presence of particulate matter, and other variables thought to influence/exacerbate erosion corrosion. Distinct phenomena thought to contribute to erosion corrosion or “flow-induced failure”, including concentration cell corrosion, cavitation, particle/bubble impingement, and high velocity impingement, are explored in detail along with conventional erosion corrosion testing methods. Existing recommendations to prevent erosion corrosion in copper pipes are evaluated and inconsistencies in available guidelines are examined.
Mind the overlap: how system problems contribute to cognitive failure and diagnostic errors
Authors: Gupta Ashwin , Harrod Molly , Quinn Martha , Manojlovich Milisa , Fowler Karen E. , Singh Hardeep , Saint Sanjay , Chopra Vineet 
Published: July 2018

Abstract

Background
Traditionally, research has examined systems- and cognitive-based sources of diagnostic error as individual entities. However, half of all errors have origins in both domains.

Methods
We conducted a focused ethnography of inpatient physicians at two academic institutions to understand how systems-based problems contribute to cognitive errors in diagnosis. Medicine teams were observed on rounds and during post-round work after which interviews were conducted. Field notes related to the diagnostic process and the work system were recorded, and findings were organized into themes. Using deductive content analysis, themes were categorized based on a published taxonomy to link systems-based contributions and cognitive errors such as faulty data gathering, information processing, data verification and errors associated with multiple domains.

Results
Observations, focus groups and interviews of 10 teams were conducted between January 2016 and April 2017. The following themes were identified: (1) challenges with interdisciplinary communication and communication within the electronic medical record (EMR) contributed to faulty data gathering; (2) organizational structures such as the operation of consulting services in silos promoted faulty information processing; (3) care handoffs led to faulty data verification and (4) interruptions, time constraints and a cluttered physical environment negatively influenced multiple cognitive domains.

Conclusions
Systems-based factors often facilitate and promote cognitive problems in diagnosis. Linking systems-based contributions to downstream cognitive impacts and intervening on both in tandem may help prevent diagnostic errors.
The “unnatural” French novel of today: Éric Chevillard’sL’Auteur et moi
Authors: Wagner Eva S. 
Published: July 2018

AbstractChevillard’s novelL’Auteur et moi(2012) touches on a problem which is paradigmatic for contemporary French prose (and perhaps “postmodern” literature in general), namely the problem of literary authenticity. Are the “unnatural” dimensions of this novel – especially its persistent irony, its playful rejection of generic norms and its attacks on the interpretative authority of its readers – playful but futile devices which lack any authentic narrative concern? Or do they represent a topical and authentic answer to the challenges of an “exhausted” genre? The present paper elaborates on this question by analysing, on the one hand, the “unnatural” (and simultaneously highly comical) devices of the novel in detail. This analysis is centred, firstly, on Chevillard’s multifaceted parody on the conventions of both narrative and non-narrative (argumentative, lyrical, scientific) discourse and, secondly, on the ways in which the novel provokes and challenges professional readers – both by the subversive use of literary-theoretical categories (author; narrator; implied author) and by the anticipation and depreciation of its own hermeneutic reception. On the other hand, this paper interprets Chevillard’s novel as the expression of an authentic literary effort which manifests itself not in the narrative contents, but in the novel’s “unnatural” composition, which offers three exits from the generic impasse with which the present-day French novel struggles.
Food addiction: is it a nosological category or a psychopathological dimension? Preliminary results of an Italian study
Authors: Piccinni Armando , Marazziti Donatella , Cargioli Claudio , Mauri Mauro , Stallone Tiziana 
Published: July 2018

Abstract

Background
Food addiction (FA) is a controversial concept, denoting the craving for certain foods. Given the little information available, the aim of this study was to evaluate the possible relationships between FA and full-blown and subthreshold psychopathology or eating behaviors in subjects consulting nutritional biologists.

Materials and methods
Three-hundred and fifty subjects completed the following self-questionnaires: Yale Food Addiction Scale (YFAS), Structured Clinical Interview for Mood Spectrum, Self-Report, Lifetime Version (MOOD-SR-LT), Symptom Checklist-90-Revised (SCL-90-R), Structured Clinical Interview for Anorexic-Bulimic Spectrum, Self-Report, Lifetime Version (ABS-SR-LT).

Results
Most of the subjects were women (n = 278) and the remaining were 72 men. A large proportion of the subjects (77.1%) had a YFAS score <3 and 22.9% ≥3, with no difference between men and women. The YFAS scores ≥3 were significantly and positively related to the all ABS-SR-LT domains, as well as to three dimensions (Depression, Hypomania, Rhythmicity) of the MOOD-SR-LT, and some SCL-90-R domains (Sensitivity, Psychoticism, General Symptom Index and Positive Symptom).

Conclusion
Our data, while indicating that FA is related to different subthreshold psychopathological domains, in particular, with both depressive and manic symptoms, as well as with rhythmicity of mood spectrum, or with eating subthreshold symptoms, would suggest that it might be a dimension underlying different conditions or symptom clusters.

Authors: Singla Deepika , Hussain M. Ejaz 
Published: July 2018

AbstractBackgroundAlthough a significant amount of research has been conducted on handgrip strength and its association with anthropometric variables, very few researchers have focused on assessment of back strength and its relationship with anthropometric variables in cricketers.ObjectiveTo investigate the degree of correlation between handgrip strength and back strength in cricket players of different maturity levels and to find the correlations of handgrip strength and back strength with anthropometric variables of age, height, body weight and body mass index (BMI).MethodsTwenty-four adolescents; aged 16.6 ± 0.8 years and 32 adult cricketers aged 24 ± 4.6 years were tested for height, body weight, BMI, hand grip strength and back strength. t values, Cohen’s d and Pearson’s correlation coefficients were calculated.ResultsHand grip strength and back strength were not found to correlate with each other at p ≤ 0.05 in adolescent players while a statistically significant large sized correlation was observed in adult cricketers at p = 0.001. Back strength and body weight were found to have a statistically significant moderate sized correlation with each other (r = 0.453 in the adolescent group and r = 0.355 in the adult group). Significant positive correlations were observed for left hand grip strength with height, body weight and BMI and also between back strength and age in the adult population of cricketers.ConclusionA significantly large correlation exists between handgrip strength and back strength in adult cricketers with no such correlation found for adolescent cricketers. Data of the present study justify its utility in the case of selection, assessment and rehabilitation of cricket players.
An examination of eating disorder education and experience in a 1-month adolescent medicine rotation: what is sufficient to foster adequate self-efficacy?

Published: July 2018

AbstractObjectiveMedical students and professionals report receiving limited education/training related to treating eating disorders. Because medical professionals are the point of initial contact for these patients and are involved necessarily in their treatment, sufficient knowledge on identification and intervention are imperative. This research set out to examine the impact of the eating disorder education and experience offered through a 1-month Adolescent Medicine rotation at a medical university on medical student/resident self-efficacy.MethodsThe 1-month rotation includes a standardized patient (SP) simulation, 1.5 h of didactic education, and 1 day observing the MD, nutritionist and psychologist within the outpatient Multidisciplinary Child/Adolescent Eating Disorders Clinic. All residents’ (n = 132) eating disorder self-efficacy was assessed before (PRE) completing simulation and didactic session and again at the end of the 1-month rotation (END). Self-efficacy was also assessed after simulation and before the didactic session for group 1 (n = 92) and after simulation and didactic session for group 2 (n = 40).ResultsFor group 1, self-efficacy was not significantly impacted PRE to POST. For group 2, self-efficacy significantly improved PRE to POST. POST to END changes were significant for both groups; however, group 2 scored significantly better across all self-efficacy areas at END.ConclusionResident training in eating disorders requires more than is offered in many residency programs. SP simulation is strengthened as an effective training tool in assessing and promoting resident self-efficacy if it is followed by didactic education. Clinical observation and extended practice that includes ongoing guidance/feedback on performance is recommended in fostering self-efficacy.
Effect of iconic gestures on second language vocabulary retention in a naturalistic setting
Authors: Lewis Tasha N , Kirkhart Matthew 
Published: July 2018

Abstract
There is a growing body of evidence that suggests that the learning of new vocabulary during second language acquisition is facilitated by associating words with gestures. This study investigates the learning of new vocabulary words when paired with congruent and incongruent iconic gestures using instructional and testing procedures consistent with current second language pedagogical practices. Results indicate that incongruent gestures inhibit learning, while congruent iconic gestures facilitate vocabulary acquisition when participants were encouraged to pay attention to the use of the gesture when studying new words. Further analyses suggest that, as has been found repeatedly, nouns are easier to remember than verbs. However, gestures are most helpful with learning adjectives compared to nouns and verbs.
Business process management for Industry 4.0 – Three application cases in the DFKI-Smart-Lego-Factory
Authors: Rehse Jana-Rebecca , Dadashnia Sharam , Fettke Peter 
Published: July 2018

Abstract
The advent of Industry 4.0 is expected to dramatically change the manufacturing industry as we know it today. Highly standardized, rigid manufacturing processes need to become self-organizing and decentralized. This flexibility leads to new challenges to the management of smart factories in general and production planning and control in particular. In this contribution, we illustrate how established techniques from Business Process Management (BPM) hold great potential to conquer challenges in Industry 4.0. Therefore, we show three application cases based on the DFKI-Smart-Lego-Factory, a fully automated “smart factory” built out of LEGO® bricks, which demonstrates the potentials of BPM methodology for Industry 4.0 in an innovative, yet easily accessible way. For each application case (model-based management, process mining, prediction of manufacturing processes) in a smart factory, we describe the specific challenges of Industry 4.0, how BPM can be used to address these challenges, and, their realization within the DFKI-Smart-Lego-Factory.

Abstract

Background:
Vitamin D regulates the concentrations of calcium and phosphate in blood and promotes the growth and remodeling of bones. The circulating active form of vitamin D, 1,25-dihydroxyvitamin D, binds to the vitamin D receptor (VDR), which heterodimerizes with the retinoid X receptor to regulate the expression of target genes. Inactivating mutations in the VDR gene cause hereditary vitamin D-resistant rickets (HVDRR), a rare disorder characterized by an early onset of rickets, growth retardation, skeletal deformities, hypocalcemia, hypophosphatemia and secondary hyperparathyroidism, and in some cases alopecia.

Methods:
We describe eight new HVDRR patients from four unrelated consanguineous families. The VDR gene was sequenced to identify mutations. The management of patients over a period of up to 11 years following the initial diagnosis is assessed.

Results:
Although all patients exhibit main features of HVDRR and carry the same c.885C>A (p.Y295*) loss of function mutation in the VDR gene, there was heterogeneity of the manifestations of HVDRR-associated phenotypes and developmental milestones. These eight patients were successfully treated over a period of 11 years. All clinical symptoms were improved except alopecia.

Conclusions:
The study concludes that VDR sequencing and laboratory tests are essential to confirm HVDRR and to assess the effectiveness of the treatment.
Thyroid storm after choking
Authors: Creo Ana L. , Cannon Bryan C. , Pittock Siobhan T. 
Published: July 2018

Abstract

Background:
A thyroid storm (TS) is a rare, but life-threatening condition in hyperthyroid patients. Mortality in adult TS patients may be as high as 10%. Typically, a trigger precipitates the storm in hyperthyroid patients.

Case presentation:
We report the case of an adolescent girl with untreated hyperthyroidism who developed fulminant TS after a significant choking episode. Initially, she was found to have neck swelling and tachycardia leading providers to suspect infection. She deteriorated after a CAT Scan (CT) was performed with iodine contrast, potentially worsening storm symptoms. Here, we describe the case, the treatment strategy and propose a treatment modification for pediatric patients.

Conclusions:
While many children are found to have minor abnormalities in thyroid studies, this case highlights the critical importance of prompt medical attention for any child with significantly elevated free thyroxine (FT4) levels as morbidity can occur when left untreated.

Authors: da Silva Martins Amanda , Barbosa Baker Méio Maria Dalva , Gomes Saint Clair S. , Lima Paola Azara Tabicas , Milanesi Brunna Grazziotti , Moreira Maria Elisabeth Lopes 
Published: July 2018

Abstract

Objective
To compare growth and body composition of preterm infants (gestational age <32 weeks) with and without bronchopulmonary dysplasia (BPD).

Methods
A prospective cohort involving three neonatal units in the public health system of the Brazilian city of Rio de Janeiro. Inclusion: newborns with gestational age <32 weeks. Exposure: BPD. Anthropometric measurements were performed at birth and at 1 month of infant corrected age. Body composition was measured using an air displacement plethysmography (ADP) (PEA POD®) at 1 month of infant corrected age.

Results
Ninety-five newborns were eligible, of which 67 were included, 32.8% of them with BPD. Newborns with BPD presented lower gestational age at birth, greater need for resuscitation in the delivery room, received parenteral nutrition (PN) for a longer period of time, achieved lower weights during hospital stay and required more time to reach a full enteral diet. No statistically significant differences were observed in relation to anthropometric measurements and body composition at 1 month of infant corrected age between the groups with and without BPD.

Conclusion
This study, unlike previous ones, has shown that children who developed BPD were able to regain growth, as measured by anthropometric measures, with no change in body composition at 1 month of infant corrected age.
The rodent fauna from the Neolithic human settlement of Tepecik-Çiftlik (Niğde, Turkey)
Authors: Erdal Ozan , Sen Sevket , Erturaç M. Korhan , Bıçakçı Erhan 
Published: July 2018

AbstractThe primary aim of this study was to establish for the very first time the results on the rodent fauna gathered from the ongoing Neolithic excavations at the Tepecik-Çiftlik site in southern Cappadocia (Niğde, Turkey). So far, the fauna being study is represented by species of arvicolines (Microtuscf.arvalisandArvicolacf.amphibius), murines (Muscf.musculus), sousliks (Spermophilus xanthoprymnus), hamsters (Mesocricetus brandti) and mole-rats (Spalax xanthodon), and their remains are described in detail. Paleoenvironmental assumption based on common preferences of the fauna elements indicates, at first sight, a rather dry steppe environment with sparse plant cover or perennial short grasses. On the other hand, the presence ofArvicolacf.amphibiuspoints out streams and marsh-like vegetation cover with bodies of water . The predation or burn marks observed on some specimens and the presence of subterraneous rodents raise questions concerning their taphonomy.
Facile preparation of a Ni/MgAl2O4 catalyst with high surface area: enhancement in activity and stability for CO methanation
Authors: Wang Shengjia , Tian Zhiwei , Liu Qing , Qiao Yingyun , Tian Yuanyu 
Published: July 2018

Abstract
To enhance the performance of anti-coking and anti-sintering of the Ni-based catalysts during the reaction process of CO methanation, we synthesized a group of catalysts denoted as “Ni-xMgAl2O4” via the modified co-precipitation method utilizing carbon black as hard template. The addition of carbon black could significantly improve the specific surface area of MgAl2O4 to 235.8 m2 g−1. The Ni catalysts supported on high-surface-area MgAl2O4 (Ni-0.25MA) exhibited enhanced catalytic performance and hydrothermal stability in comparison with the conventional Ni-based magnesia alumina spinel catalysts with the same NiO content. In the process of 120-h stability test, the Ni-0.25MA catalyst exhibited remarkable improvement in both anti-sintering and anti-coking. After a series of characterizations, we found that the addition of carbon black could make more pores over MgAl2O4, resulting in the supported Ni particles being anchored in the pore rather than on the outside surface of support. This structure enhanced the dispersion of nickel nanoparticles, thus strengthening the interaction between nickel species and the MgAl2O4 support, which led to the promotion in catalytic activity and stability of high-surface-area Ni/MgAl2O4.
