Prognostic factors for premature growth plate arrest as a complication of the surgical treatment of fractures of the medial malleolus in children
Authors: Petratos D. V. , Kokkinakis M. , Ballas E. G. , Anastasopoulos J. N. 
Published: February 2013

McFarland fractures of the medial malleolus in children, also classified as Salter–Harris Type III and IV fractures, are associated with a high incidence of premature growth plate arrest. In order to identify prognostic factors for the development of complications we reviewed 20 children with a McFarland fracture that was treated surgically, at a mean follow-up of 8.9 years (3.5 to 17.4). Seven children (35%) developed premature growth arrest with angular deformity. The mean American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale for all patients was 98.3 (87 to 100) and the mean modified Weber protocol was 1.15 (0 to 5). There was a significant correlation between initial displacement (p = 0.004) and operative delay (p = 0.007) with premature growth arrest. Both risk factors act independently and additively, such that all children with both risk factors developed premature arrest whereas children with no risk factor did not. We recommend that fractures of the medial malleolus in children should be treated by anatomical reduction and screw fixation within one day of injury.

The topological decomposition of inverse limits of iterated wreath products of finite Abelian groups
Authors: Woryna Adam 
Published: March 2013

Abstract.
Let be an arbitrary infinite sequence of nontrivial finite Abelian transitive groups such that the topological rank ρ of the infinite Cartesian product of these groups is finite. We consider the corresponding inverse limit of iterated permutational wreath products. By using the geometric language of automorphisms of a certain rooted tree we show that the group is topologically generated by the union of two sets each containing ρ elements and such that both the group generated by S and the group generated by are free Abelian groups of rank ρ. Moreover, the group G generated by the above union decomposes as
a semidirect product of the group generated by one of these sets and the normal closure of the other set, and the semigroup generated by this union is a free product of semigroups generated by S and , respectively. We derive other algebraic properties of the group G. In particular, the condition for the groups to be finitely generated as profinite groups and some nontrivial results concerning topological ranks of their subgroups are given in this way. For example, for every our construction gives an explicit and naturally defined finitely generated subgroup of an inverse limit of iterated wreath products of finite Abelian groups such that the rank of this subgroup and the topological rank of its topological closure differ by n.
Tattoo, piercing, and adolescent tobacco consumption
Authors: Guéguen Nicolas 
Published: February 2013

Abstract
The objective of the study was to evaluate the link between tattoos and/or piercings and young people’s tobacco consumption.
Methods: A total of 2587 students (1168 females and 1419 males) were asked about tattoos, piercings, and tobacco consumption.
Results: Young men and young girls who had tattoos and/or wore piercings were more likely to report smoking behavior, earlier smoking behavior, and higher cigarette consumption per day. It was also found that both with men and women, the combined effects of piercings and tattoos were associated with an increase in smoking behavior.
Conclusion: Piercings and/or tattoos as well as combined piercings and tattoos appeared as markers of tobacco consumption. Such marks could serve as signs for educators, parents, and physicians.
Service-learning from the views of university teachers: a qualitative study based on focus groups
Authors: Shek Daniel T.L. , Chan Stephen C.F. 
Published: February 2013

Abstract
Under the New Undergraduate Curriculum at The Hong Kong Polytechnic University (PolyU), students are required to take a 3-credit subject to fulfill service-learning requirements. To understand the views of teachers regarding service-learning, five focus group interviews (n=33) are conducted to examine the perceived characteristics and myths of service-learning as well as colleagues’ views on the policy at PolyU. Results showed that most informants are aware of service-learning and have seen its benefits to both students and teachers. Most informants also possess positive views about service-learning. Nevertheless, in terms of service-learning at PolyU, three different groups of views on service-learning are observed, namely, positive, negative, and mixed views. This paper also discusses teachers’ views on the anticipated difficulties of service-learning implementation and the ways, by which to promote the subject in the PolyU context.
Helping adolescents with greater psychosocial needs: the extension phase of the project P.A.T.H.S. in Hong Kong
Authors: Shek Daniel T.L. , Sun Rachel C.F. 
Published: February 2013

Abstract
Subjective outcome evaluation data were collected from 24,198 students of 236 schools after completion of the Tier 2 Program in the second year of the Extension Phase of the Project P.A.T.H.S. in Hong Kong. Using schools as units of analysis, results showed that the program, implementers, and effectiveness were perceived in a positive manner. Although subjective outcome evaluation findings differed across participant types, grades, and program types did not show significant differences on the outcome measures. Consistent with previous reports, perceived effectiveness of the program was significantly predicted by student perceptions about the program and program instructor. These findings provide support for the claim that the Tier 2 Program is effective in promoting positive development among adolescents with greater psychosocial needs in the extension phase of the Project P.A.T.H.S. in Hong Kong.

OBJECTIVES:
Central line-associated bloodstream infections (CLABSIs) are a significant source of morbidity and mortality in the NICU. In 2010, Medicaid was mandated not to pay hospitals for treatment of CLABSI; however, the source of CLABSI data for this policy was not specified. Our objective was to evaluate the accuracy of hospital administrative data compared with CLABSI confirmed by an infection control service.

METHODS:
We evaluated hospital administrative and infection control data for newborns admitted consecutively from January 1, 2008, to December 31, 2010. Clinical and demographic data were collected through chart review. We compared cases of CLABSI identified by administrative data (International Classification of Diseases, Ninth Revision, Clinical Modification 999.31) with infection control data that use national criteria from the Centers for Disease Control and Prevention as the gold standard. To ascertain the nature possible deficiencies in the administrative data, each patient's medical record was searched to determine if clinical phrases that commonly refer to CLABSI appeared.

RESULTS:
Of 2920 infants admitted to the NICU during our study period, 52 were identified as having a CLABSI: 42 by infection control data only, 7 through hospital administrative data only, and 3 appearing in both. Against the gold standard, hospital administrative data were 6.7% sensitive and 99.7% specific, with a positive predictive value of 30.0% and a negative predictive value of 98.6%. Only 48% of medical records indicated a CLABSI.

CONCLUSIONS:
Our findings from a major children’s hospital NICU indicate that International Classification of Diseases, Ninth Revision, Clinical Modification code 993.31 is presently not accurate and cannot be used reliably to compare CLABSI rates in NICUs.
Early Morphological Changes in Al Lines During Current Stressing
Authors: Schührer H. , Brückl H. , Reiss G. 
Published: March 2013

ABSTRACTThis paper will show that scanning force microscopy (also known as atomic force microscopy (AFM)) is a good tool to observe the microscopic changes in the morphology of metallic conductor lines during in situ current stressing with a very high spatial resolution. AFM was used to image AlSi1%Cu0.5% meander structures (1 μm thick, 4 μm wide, 44 mm long) at room temperature during current stressing. The microstructure of the material showed significant changes already at a current density of 1.5 MA/cm2, still before voiding and hillock growth occurred. Growth and reduction of the grain sizes and also grooving and widening of the grain boundaries were observed.

Published: March 2013

Summary

Background and objectives
Candidates with AKI including hepatorenal syndrome often recover renal function after successful liver transplantation (LT). This study examined the incidence and risk factors associated with renal nonrecovery within 6 months of LT alone among those receiving acute renal replacement therapy (RRT) before LT.

Design, setting, participants, & measurements
Scientific Registry of Transplant Recipients data were linked with Centers for Medicare and Medicaid Services ESRD data for 2112 adult deceased-donor LT-alone recipients who received acute RRT for ≤90 days before LT (February 28, 2002 to August 31, 2010). Primary outcome was renal nonrecovery (post-LT ESRD), defined as transition to chronic dialysis or waitlisting or receipt of kidney transplant within 6 months of LT. Cumulative incidence of renal nonrecovery was calculated using competing risk analysis. Cox regression identified recipient and donor predictors of renal nonrecovery.

Results
The cumulative incidence of renal nonrecovery after LT alone among those receiving the pre-LT acute RRT was 8.9%. Adjusted renal nonrecovery risk increased by 3.6% per day of pre-LT RRT (P<0.001). Age at LT per 5 years (P=0.02), previous-LT (P=0.01), and pre-LT diabetes (P<0.001) were significant risk factors of renal nonrecovery. Twenty-one percent of recipients died within 6 months of LT. Duration of pretransplant RRT did not predict 6-month post-transplant mortality.

Conclusions
Among recipients on acute RRT before LT who survived after LT alone, the majority recovered their renal function within 6 months of LT. Longer pre-LT RRT duration, advanced age, diabetes, and re-LT were significantly associated with increased risk of renal nonrecovery.
Evidences of Multicomponent Structure of the Migratory Stock and Morphological Distinctions of Shads from the Genus Alosa (Clupeaformes, Alosiinae) of the Sea of Azov
Authors: Mezhzherin S. V. , Vernygora O. V. 
Published: March 2013

Abstract
Migratory stocks of shads passing through the Kerch strait during their seasonal migrations consist of three groups of specimens, that can be identified based on the number of gill rakers on the first arch. These are so called Kerch shad A. maeotica (50.2 %), Pontic shad A. immaculata (48.7 %) and Caspian shad A. caspia (1.1 %). This ratio of species in the region remains stable for the last 60 years. Populations of Kerch and Pontic shads have similar age structure and sex ratio with a shift toward females 52-54 %. Specimens of A. maeotica have greater linear size and weight than those of A. immacuta, that indicates higher growth rate of the former. Analysis of 26 body measurements shows definite differences between these shads in their absolute features, there are also some differences in the proportions of the head. Nevertheless, degree and reproducibility of interspecific differences during various periods of time, do not allow for the reliable discrimination of specimens of these species assumed by some researchers
Correlations Between Hardness of Food and Craniodental Traits in Nine Myotis Species (Chiroptera, Vespertilionidae)

Absract
We studied 8 skull and 42 dental characters in nine Myotis species (M. myotis, M. blythii, M. bechsteinii, M. dasycneme, M. emarginatus, M. nattereri, M. daubentonii, M. brandtii, M. mystacinus) to analyze correlations between hardness of food and skull and dental traits. Contrary to the common bat pattern, Myotis that are specialized on hard-shelled dietary items tend to have relatively narrow skull and long tooth rows. The dentition of durophagous Myotis is composed by relatively enlarged second and reduced third molars.
Avulsion Fracture of the Anterior Superior Iliac Spine

Published: March 2013

The patient was a 17-year-old adolescent male who was referred to a physical therapist for a chief complaint of anterior right hip pain. The physical therapist reviewed the patient's radiographs, which had been completed and interpreted as normal prior to referral, and determined that there were radiographic signs present that may be concerning for an avulsion fracture. Further evaluation through magnetic resonance imaging confirmed the presence of an avulsion fracture at the right anterior superior iliac spine.

Published: March 2013

Object
The object of this study was to determine the tolerability and activity of lacosamide in patients with brain tumors.

Methods
The authors reviewed the medical records at 5 US academic medical centers with tertiary brain tumor programs, seeking all patients in whom a primary brain tumor had been diagnosed and who were taking lacosamide.

Results
The authors identified 70 patients with primary brain tumors and reviewed seizure frequency and toxicities. The majority of the patients had gliomas (96%). Fifty-five (78%) had partial seizures only, and 12 (17%) had generalized seizures. Most of the patients (74%) were started on lacosamide because of recurrent seizures. Forty-six patients (66%) reported a decrease in seizure frequency, and 21 patients (30%) reported stable seizures. Most of the patients (54 [77%]) placed on lacosamide did not report any toxicities.

Conclusions
This retrospective analysis demonstrated that lacosamide was both well tolerated and active as an add-on antiepileptic drug (AED) in patients with brain tumors. Lacosamide's novel mechanism of action will allow for concurrent use with other AEDs, as documented by its activity across many different types of AEDs used in this patient population. Larger prospective studies are warranted.
Chicken embryonic brain: an in vivo model for verifying neural stem cell potency
Authors: Kharazi Alex , Levy Michael L. , Visperas Maria Cristina , Lin Chih-Min 
Published: March 2013

Object
The multipotency of neural stem cells (NSCs) can be assessed in vitro by detection of stage-specific markers in response to a suitable differentiation signal. This test is frequently used because it is fast and affordable. However, it is not clear how the in vitro potential for multilineage differentiation and stem cell marker expression would reflect the ability of NSCs to engraft into the brain following transplantation. The authors undertook this study to directly compare the in vitro potency and in vivo migration of human NSCs (hNSCs) expanded under conditions of gradually increased concentration of fetal bovine serum (FBS) as a maturation factor.

Methods
Human NSCs isolated from fetal brain were propagated in serum free media (SF-hNSCs) and in media containing 0.1% and 0.2% serum. At Passage 4 in tissue culture the NSCs were harvested and either differentiated in vitro or transplanted into the lateral ventricle of chicken embryonic brain at the late stage of its development (Hamburger and Hamilton Stage 26). The in vitro differentiation was evaluated by immunostaining with neural or glial specific markers, and the in vivo migration was assessed using immunohistology.

Results
The authors found that SF-hNSCs successfully engrafted into the chicken embryonic brain, which correlated with their ability to differentiate in vitro. NSCs grown at as low as 0.1% concentration of FBS failed to demonstrate the robust in vivo migration pattern but still preserved the capability to differentiate in vitro. Furthermore, NSCs generated in media containing a higher concentration of FBS (0.2%) lost both the in vivo engraftment and in vitro differentiation potential.

Conclusions
The present study suggests that marker expression and in vitro differentiation assays might not provide adequate information regarding the behavior of NSCs following their transplantation. The in vivo migration following injection into chicken embryonic brain may provide an important assay of the potency of NSCs.

Published: March 2013

BackgroundNutritional support is important for maximizing clinical outcomes in critically ill patients, but enteral nutritional intake is often inadequate.ObjectiveTo assess the nutritional intake of energy and protein during the first 4 days after initiation of enteral feeding and to examine the relationship between intake and interruptions of enteral feeding in Korean patients in intensive care.MethodsA cohort of 34 critically ill adults who had a primary medical diagnosis and received bolus enteral feeding were studied prospectively. Energy and protein requirements were determined by using the Harris-Benedict equation and the American Dietetic Association equation. Energy and protein intake prescribed and received and the reasons for and lengths of feeding interruptions were recorded for 4 consecutive days immediately after enteral feeding began.ResultsAlthough the differences between requirements and intakes of energy and protein decreased significantly, patients did not receive required energy and protein intake during the 4 days of the study. Energy intake prescribed was consistently less than required on each of the 4 days. Enteral nutrition was withheld for a mean of 6 hours per patient for the 4 days. Prolonged feeding interruptions due to gastrointestinal intolerance (r= –0.874; P &lt; .001) and procedures (r= –0.839; P = .005) were negatively associated with the percentage of prescribed energy received.ConclusionsEnteral nutritional intake was insufficient in bolus-fed Korean intensive care patients because of prolonged feeding interruptions and underprescription of enteral nutrition. Feeding interruptions due to gastrointestinal intolerance and procedures were the main contributors to inadequate energy intake. (American Journal of Critical Care. 2013;22:126–135)
A Transformed Coordinates Shallow Water Model for the Head of the Bay of Bengal Using Boundary-Fitted Curvilinear Grids
Authors: Hussain Farzana 
Published: March 2013

AbstractThe Bay of Bengal is surrounded by coastline except to the south, where there is open sea. The coastline bends most sharply along the coast of Bangladesh, and there are many small and large islands in the off shore region there. In order to incorporate the island boundaries and the curved coastline properly, in any numerical scheme it is often necessary to consider a very fine grid resolution along the coastal belts whereas this is unnecessary away from the coasts. However, a very fine resolution involves more memory and more CPU time in the numerical solution process, and invites numerical instability. On the other hand, boundary-fitted curvilinear grids in hydrodynamic models for coastal seas, bays and estuaries not only fit to the coastline but also render the finite difference schemes simpler and more accurate. In this article, the boundary-fitted curvilinear grids for the model represent the complete boundary of the area considered by four curves defined by four functions, and the four boundaries of two of the larger islands are then represented approximately by two general functions. An appropriate independent coordinate transformation maps the curvilinear physical area to a square domain, and each island boundary is transformed to a rectangle within this square domain. The vertically integrated shallow water equations are transformed to the new space domain, and solved by a regular explicit finite difference scheme. The model is applied to compute the water levels due to astronomical tides, and also the water levels due to surges associated with tropical storms that hit the coast of Bangladesh.
