Psychological Outcome of Injured Workers at 3 Months after Occupational Injury Requiring Hospitalization in Taiwan: Kuan‐Han LIN, et al. Institute of Occupational Medicine and Industrial Hygiene, National Taiwan University School of Public Health, Taiwan—Introduction: After a traumatic event, a significant proportion of victims develop psychiatric disorders. Trauma has been an important ailment among workers. This study aimed to determine the prevalence of post‐traumatic stress disorder (PTSD) and other psychiatric disorders at three months after occupational injuries.MethodsOur study candidates were injured workers in Taiwan who were hospitalized for 3 days or longer and Received hospitalization benefits from the Labor Insurance program. A two‐staged survey study was conducted. A self‐reported questionnaire including the Brief Symptom Rating Scale (BSRS50) and Post‐traumatic Symptom Checklist (PTSC) was sent to workers at 3 months after injury. Those who met the criteria were recruited for the second stage phone interview with a psychiatrist using the Mini‐international Neuropsychiatric Interview (MINI).ResultsA total of 2001 workers completed the questionnaire (response rate 45.5%). Among them, 357 (17.8%) fulfilled the criteria for the MINI interview and were invited. A total of 148 (41.5%) completed the phone interview. The estimated rates of PTSD, partial PTSD (PPTSD), major depression, comorbid PTSD/PPTSD and major depression, and either PTSD/PPTSD or major depression were 2.7, 4.1, 3.0, 2.3, and 7.5%, respectively. The estimated rates of either PTSD/PPTSD or major depression among workers who suffered from intracranial injury, fracture, burn, crushing injury, and open wound of upper limbs were 10.4, 6.9, 5.9, 5.8 and 0%, respectively.ConclusionsAt three months after occupational injuries, a significant proportion of workers suffered from psychiatric disorders. The rates of psychiatric disorders occurring after intracranial injuries were significantly higher than those occurring after non‐intracranial injuries.

A Guillain‐Barré Syndrome‐like Neuropathy Associated with Arsenic Exposure: Sunyoung KIM, et al. Department of Neurology, Ulsan University Hospital, University of Ulsan College of Medicine, Republic of Korea—ObjectivesWe report on a patient presenting with an isolated polyneuropathy mimicking Guillain‐Barré syndrome (GBS) associated with arsenic exposure. Case: A 43‐year‐old man visited our emergency room complaining of progressive quadri‐paresis over the prior 5 days. His clinical course with laboratory data was typical of GBS. However, because of his recent use of herbal medication, we screened for the presence of several heavy metals. Serial analyses of urinary inorganic arsenic concentrations confirmed exposure to arsenic. He was diagnosed as arsenic neuropathy mimicking GBS without any systemic manifestation of arsenic intoxication.ConclusionsThe present case study emphasizes the need to consider arsenic intoxication in patients presenting with acute demyelinating neuropathies and histories of herbal medication use.

Authors: Scotto Rosato Nancy , Correll Christoph U. , Pappadopulos Elizabeth , Chait Alanna , Crystal Stephen , Jensen Peter S. ,   on behalf of the Treatment of Maladaptive Aggressive in Youth Steering Committee
Published: May 2012

OBJECTIVE:
To develop guidelines for management and treatment of maladaptive aggression in youth in the areas of psychosocial interventions, medication treatments, and side-effect management.

METHODS:
Evidence was assembled and evaluated in a multistep process, including systematic reviews of published literature; an expert survey of recommended practices; a consensus conference of researchers, policymakers, clinicians, and family advocates; and review by the steering committee of successive drafts of the recommendations. The Center for Education and Research on Mental Health Therapeutics Treatment of Maladaptive Aggression in Youth guidelines reflect a synthesis of the available evidence, based on this multistep process.

RESULTS:
This article describes the content, rationale, and evidence for 11 recommendations. Key treatment principles include considering psychosocial interventions, such as evidence-based parent and child skills training as the first line of treatment; targeting the underlying disorder first following evidence-based guidelines; considering individual psychosocial and medical factors, including cardiovascular risk in the selection of agents if medication treatment (ideally with the best evidence base) is initiated; avoiding the use of multiple psychotropic medications simultaneously; and careful monitoring of treatment response, by using structured rating scales, as well as close medical monitoring for side effects, including metabolic changes.

CONCLUSIONS:
Treatment of children with maladaptive aggression is a “moving target” requiring ongoing assimilation of new evidence as it emerges. Based on the existing evidence, the Treatment of Maladaptive Aggression in Youth guidelines provide a framework for management of maladaptive aggression in youth, appropriate for use by primary care clinicians and mental health providers.
Meta-analysis of Long-Chain Polyunsaturated Fatty Acid Supplementation of Formula and Infant Cognition
Authors: Qawasmi Ahmad , Landeros-Weisenberger Angeli , Leckman James F. , Bloch Michael H. 
Published: May 2012

BACKGROUND AND OBJECTIVE:
Infant formula is supplemented with long-chain polyunsaturated fatty acids (LCPUFAs) because they are hypothesized to improve cognition. Several randomized controlled clinical trials have examined the effect of LCPUFA supplementation of infant formula on cognitive development. We conducted this meta-analysis to examine the efficacy of LCPUFA supplementation of infant formula on early cognitive development.

METHODS:
Two authors searched PubMed, PsychInfo, and Scopus for randomized controlled clinical trials assessing the efficacy of LCPUFA supplementation of infant formulas on cognition. Our analysis was restricted to randomized controlled clinical trials that examined the effect of LCPUFA supplementation on infant cognition using Bayley Scales of Infant Development. Our primary outcome was the weighted mean difference in Bayley Scales of Infant Development score between infants fed formula supplemented with LCPUFA compared with unsupplemented formula. We conducted secondary subgroup analyses and meta-regression to examine the effects of study sample, LCPUFA dose, and trial methodologic quality on measured efficacy of supplementation.

RESULTS:
Twelve trials involving 1802 infants met our inclusion criteria. Our meta-analysis demonstrated no significant effect of LCPUFA supplementation of formula on infant cognition. There was no significant heterogeneity or publication bias between trials. Secondary analysis failed to show any significant effect of LCPUFA dosing or prematurity status on supplementation efficacy.

CONCLUSIONS:
LCPUFA supplementation of infant formulas failed to show any significant effect on improving early infant cognition. Further research is needed to determine if LCPUFA supplementation of infant formula has benefits for later cognitive development or other measures of neurodevelopment.

Published: May 2012

OBJECTIVE:
We sought to determine if a center’s approach to care of premature infants at the youngest gestational ages (22–24 weeks’ gestation) is associated with clinical outcomes among infants of older gestational ages (25–27 weeks’ gestation).

METHODS:
Inborn infants of 401 to 1000 g birth weight and 22 0/7 to 27 6/7 weeks’ gestation at birth from 2002 to 2008 were enrolled into a prospectively collected database at 20 centers participating in the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network. Markers of an aggressive approach to care for 22- to 24-week infants included use of antenatal corticosteroids, cesarean delivery, and resuscitation. The primary outcome was death before postnatal day 120 for infants of 25 to 27 weeks’ gestation. Secondary outcomes were the combined outcomes of death or a number of morbidities associated with prematurity.

RESULTS:
Our study included 3631 infants 22 to 24 weeks’ gestation and 5227 infants 25 to 27 weeks’ gestation. Among the 22- to 24-week infants, use of antenatal corticosteroids ranged from 28% to 100%, cesarean delivery from 13% to 65%, and resuscitation from 30% to 100% by center. Centers with higher rates of antenatal corticosteroid use in 22- to 24-week infants had reduced rates of death, death or retinopathy of prematurity, death or late-onset sepsis, death or necrotizing enterocolitis, and death or neurodevelopmental impairment in 25- to 27-week infants.

CONCLUSIONS:
This study suggests that physicians’ willingness to provide care to extremely low gestation infants as measured by frequency of use of antenatal corticosteroids is associated with improved outcomes for more-mature infants.
Regenerative Treatment for a Peri‐Implantitis‐Affected Implant: A Case Report
Authors: Froum Stuart J. 
Published: May 2012

Introduction: Peri‐implantitis is an inflammatory disease in the mucosa around an implant that results in bone loss and, if allowed to progress, can result in loss of the implant. This disease has been estimated to have a prevalence varying from 11.3% to 56%. To date, there is little evidence to indicate the most effective method of treatment of peri‐implantitis. This report describes a regenerative treatment for restoration of bone and reduction of probing depth (PD) around a peri‐implantitis‐affected implant.Case Presentation: A 67‐year‐old male patient presented with advanced peri‐implantitis around a mandibular right first molar implant that was placed and restored 3 years before his visit. An examination revealed PD of 7 to 12 mm and bone loss of 7 to 10 mm circumferentially around the implant. Treatment consisted of flap reflection, a six‐step surface decontamination, placement of enamel matrix derivative on the implant surface, and fill of the defect with combined allograft/xenografts mixed with platelet‐derived growth factor. The graft was covered with two absorbable collagen membranes, and the flap was coronally advanced and sutured. A 7‐year follow‐up revealed PD reduction of 4 to 10 mm, bone level gain of 3 to 3.5 mm, and no change in the coronal level of the mucosa (no post‐surgical recession).Conclusion: The technique used in this case report resulted in an outcome that saved the implant, brought the peri‐implant tissues back to health, and reduced PD and increased bone support around the affected implant without soft‐tissue recession.
Mitigating motion artifacts in FDK based 3D Cone-beam Brain Imaging System using markers
Authors: Bhowmik Ujjal , Zafar Iqbal M. , Adhami Reza 
Published: May 2012

Abstract
Head motion during Computed Tomographic (CT) brain imaging studies can adversely affect the reconstructed image through distortion, loss of resolution and other related artifacts. In this paper, we propose a marker based innovative approach to detect and mitigate motion artifacts in three dimensional cone-beam brain CT systems without using any external motion tracking sensor. Motion is detected using correlations between the adjacent projections. Once motion is detected, motion parameters (i.e. six degrees-of-freedom of motions) are estimated using a numerical optimization technique. Artifacts, caused by motions, are mitigated by using a modified form Feldkemp-Davis-Kress (FDK) algorithm which uses the estimated motion parameters in back-projection stage. The proposed approach has been evaluated on a modified three-dimensional Shepp-Logan phantom with a range of simulated motions. Simulation results demonstrate a quantitative and qualitative validation of motion detection and artifacts mitigation technique.
Faradaic current in different mullite materials: single crystal, ceramic and cermets
Authors: Mata-Osoro Gustavo , Moya Jose S. , Morales Miguel , Díaz L. Antonio , Schneider Hartmut , Pecharromán Carlos 
Published: May 2012

Abstract
Faradaic current measurements have been carried out on three different types of mullite: 2:1 mullite single crystals (E ⊥ c), 3:2 ceramics and 11% mullite/Mo composites. Measurements were carried out on very thin samples (60 μm) at high voltages (500 to 1000 V). Under these conditions, measurable currents were recorded even at room temperature. Results indicate notable differences between these three samples, which suggest that, although they share the same name and similar crystalline structure, binding energies and defect distributions seem to be very different. Finally, it has been seen that the excellent behaviour against dielectric breakdown of ceramic mullite does not hold for single crystals or mullite based cermets.
Development of high-strength pure magnesium and wrought magnesium alloys AZ31, AZ61, and AZ91 processed by hydrostatic extrusion with back pressure
Authors: Pachla Wacek , Mazur Andrzej , Skiba Jacek , Kulczyk Mariusz , Przybysz Sylwia 
Published: May 2012

Abstract
Cold hydrostatic extrusion with and without back pressure of commercial Mg 99.5+% and AZ31, AZ61, and AZ91 wrought magnesium alloys has been performed on a press operating up to 2000 MPa with a back pressure reaching up to 700 MPa. Application of back pressure extended the formability of Mg, and AZ-type magnesium alloys, which decreases with the increase in the Al content. Fibrous and elongated grains above 1 micrometre and nanometre scale sub-grains and grains were observed. The strength of all materials was significantly higher in comparison to materials conventionally and hydrostatically hot-extruded, hot ECAP-ed or after hot wire drawing. In comparison to materials processed by traditional methods the ultimate tensile strength increment after hydrostatic extrusion with back pressure increases gradually with an increase in Al content reaching for AZ91 almost 40%. The potential application of AZ-type magnesium alloys as semi-products for degradable medical implants or high strength structural components is indicated.

Published: May 2012

Abstract
Immobilization of ZnO nanoparticles on cotton fabrics using poly 4-styrenesulfonic acid (PSS) was studied. The cotton fabrics were firstly cationized using 3-chloro-2-hydroxypropyl trimethylammonium chloride (CHTAC) solution. The surfaces of cationized cotton were coated using a layer-by-layer technique by stepwise dipping the cationized cotton into a solution of anionic PSS polyelectrolyte and Zn(NO3)2 · 6H2O solution. The coating procedure was repeated 2, 4, and 6 times to obtain the PSS/Zn2+ multilayers coated on the cotton fabrics. The treated cotton fabrics were hydrothermally treated in NH4OH solution at 90 oC for 24 h, resulting in immobilization of ZnO nanocrystals on the cotton fabrics. The SEM, XRF, and XPS data revealed the accomplishment of ZnO immobilization on the surfaces of the treated cotton fabrics. The higher the number of PSS/Zn2+ coating layers on the fabrics, the more hydrothermally grown ZnO nanoparticles could be obtained, resulting in a higher UV protection factor when testing by the AATCC 183–2004 standard test method. All cotton fabrics with the ZnO immobilized on the surfaces were classified according to the AS/NZS 4339:1997 standard in the range of “VERY GOOD” UV protection category. The ZnO-immobilized cotton fabrics with the six PSS/Zn2+ coating layers could inhibit the growth of Staphylococcus
aureus when testing by the AATCC 147–2004 standard test method.
Relationship between the mechanical properties and the surface roughness of marble
Authors: Karaca Zeki 
Published: May 2012

Abstract
Because dimension stone is a natural building material, polishing is important, especially when deciding how the stone will be used. However, the effects of stone polishing are not fully understood. In the stone industry, determining the best polishing process is often performed by trial and error or is based on an expert's experiences. This paper reports the result of a study conducted using selected true marble specimens to determine their surface roughness values and to relate these values to their grain sizes, uniaxial compressive strengths, tensile strengths, and Böhme abrasion values. For this purpose, five different true marble specimens were selected. The significance and validity of the relationships between the mechanical properties and the final surface roughness values were interpreted using test statistics. It was found that there were statistically significant correlations between uniaxial compressive strength and tensile strength and the surface roughness of the studied marble specimens. It is not clearly known whether the Böhme abrasion loss value has any relationship with the surface roughness of the polished marble or not. It is thought that the present findings could help practitioners and consumers as well as architects and engineers to make more informed choices about the type of marble to use for specific applications.
In-situ observation of the fracture process in Al–Zn–Mg–Cu alloys
Authors: Vratnica Maja 
Published: May 2012

Abstract
In order to investigate the fracture behaviour of highly-alloyed Al–Zn–Mg–Cu alloys as a function of alloy purity, in-situ observations using scanning electron microscopy were performed during tensile testing. The observations were used to verify proposed fracture mechanisms in conjunction with microstructural and fractographic analyses along with fracture toughness tests. It was found that the fracture process is complex. The nucleation, growth, and coalescence of voids precede ductile fracture of the alloys. The decohesion and fracture of intermetallic particles (generally >1 μm in diameter) appears to be the initial event in the fracture process, while mechanism and propagation rate of fracture depend on the alloy chemistry. A tortuous crack path and reduced crack propagation rate in the least pure alloy can be closely related to a strong interaction of the crack front with intermetallic particles.
Phase equilibria in the “SnO”–SiO2–“FeO” system in equilibrium with tin–iron alloy and the potential application for electronic scrap recycling

Published: May 2012

AbstractExperimental studies have been conducted to determine the primary phases and liquidus temperatures in the pseudo-binary system “SnO”–“FeO” and the pseudo-ternary system “SnO”–SiO2–“FeO” in equilibrium with tin–iron alloy between 1148 and 1673 K, using a high-temperature equilibration and quenching technique followed by electron probe X-ray microanalysis of the phase compositions in the quenched samples. The following primary phase fields were identified: wustite (FeOx), spinel (Fe(3–x)SnxO4), fayalite (Fe2SiO4), tridymite (SiO2), tin iron silicate (Fe4Si2Sn7O16), and cassiterite (SnO2). With this new information on the chemistry of the “SnO”–SiO2–“FeO” slag this system may potentially be used for the processing and recycling of electronic scrap and the recovery of valuable minor elements.

SummaryAim of the study was to evaluate the influence of an extra corporal perfusion (cardiopulmonary bypass operation – cpb) on activation and biodistribution of 99mTc labelled granulocytes in pigs with and without inhibition of the granulocytes by a leukocyte inhibition module (LIM). The cpb is often related to an activation of granulocytes resulting in an inflammatory answer. The biological mechanisms are unsolved yet. First trials of our group showed that LIM may inhibit the activation of neutrophils and therefore antagonize a cpb-caused impairment of cardiac function. This study is the continuation of these experiments with a higher number of animals and the focus on scintigraphic imaging. Animals, material, methods: 39 German landrace pigs were subdivided into three groups: group A (control) median sternotomy without cpb, group B with cpb, group C with LIM in addition to cpb. After labelling with 99mTc-HMPAO autologues granulocytes were reinjected. Subsequently to cpb, the animals underwent scintigraphic imaging. Quantification was performed with ROI evaluation and with tissue samples (section analysis) examined in a well counter. Results: A high uptake of 99mTc-HMPAO was found in the liver. The count rates in brain, heart, lung, spleen and kidneys were far below. The amount of 99mTc-activity in the organ related to the half life corrected administered activity [%] was for the tissue samples (group A/B/C): brain 0.01/0.02/0.03; lung 12.1/8.3/11.5; heart 0.35/0.54/0.42; kidney 1.24/0.87/1.02; spleen 4.0/4.0/4.5, liver 16.8/20.9/19.6. The count rates determined by ROI-evaluation of the scintigraphic images related to the total count rate in the image [%] were (group A/B/C): brain 1.1/0.9/1.0; lung 15.6/10.4/12.2; heart 4.0/3.5/3.4; kidney 4.0/2.9/3.2; spleen 7.6/7.7/9.5, liver 23.1/36.7/31.4. A significant difference in the tracer uptake between the groups could neither be detected by scintigraphic imaging nor evaluation of tissue samples. Conclusion: Scintigraphic imaging as well as section analysis showed a comparable biodistribution of the tracer. Therefore, the initial results of our group were not confirmed with a considerably higher number of animals. Neither cpb nor the use of the LIM influenced distribution of 99mTc-labelled granulocytes in pigs significantly.
