Authors: Agarwal SK , Yadav Kajal , Nagpal Abhishek , Kochhar Aarti 
Published: October 2016

ABSTRACT

Introduction
Dental implants are one of the common lines of treatment used for the treatment of missing tooth. Various risk factors are responsible for the failure of the dental implants and occurrence of postoperative complications. Bruxism is one such factor responsible for the failure of the dental implants. The actual relation between bruxism and dental implants is a subject of long-term controversy. Hence, we carried out this retrospective analysis to assess the complications occurring in dental implants in patients with and without bruxism.

Materials and methods
The present study included 1100 patients which were treated for rehabilitation by dental implant procedure at 21 dental offices of Ghaziabad (India) from 2004 to 2014. Analyzing the clinical records of the patients along with assessing the photographs of the patients was done for confirming the diagnosis of bruxism. Clinical re-evaluation of the patients, who came back for follow-up, was done to confirm the diagnosis of bruxism. Systemic questionnaires as used by previous workers were used to evaluate the patients about the self-conscience of the condition. Estimation of the mechanical complications was done only in those cases which occurred on the surfaces of the restoration of the dental implants. All the results were analyzed by Statistical Package for Social Sciences (SPSS) software. Student's t-test and Pearson's chi-square test were used to evaluate the level of significance.

Results
In both bruxer and non-bruxers, maximum number of dental implants was placed in anterior maxillary region. Significant difference was obtained while comparing the two groups for dimensions of the dental implants used. On comparing the total implant failed cases between bruxers and non-bruxers group, statistically significant result was obtained. Statistically significant difference was obtained while comparing the two study groups based on the health parameters, namely hypertension, diabetes, and smoking habit.

Conclusion
Success of dental implant is significantly affected by bruxism. Special attention is required in such patients while doing treatment planning.

Clinical significance
For the long-term clinical success and survival of dental implants in patients, special emphasis should be given on the patient's deleterious oral habits, such as bruxism as in long run, they influence the stability of dental implants.

ABSTRACTIntroductionBehavioral management of patients forms one of the foremost components of pediatric dental treatment. Some children readily cooperate with dental treatment, while others require general anesthesia as a part of treatment protocol for carrying out various dental procedures. Hence, we evaluated the pediatric patients with and without mental retardation, who underwent dental treatment under general anesthesia.Materials and methodsThe present study analyzed the record of 480 pediatric patients reporting in the department of pedodontics from 2008 to 2014. Analysis of the records of the patients who underwent dental treatment under general anesthesia was done and all the patients were divided into two study groups depending upon their mental level. For the purpose of evaluation, the patients were also grouped according to their age; 4 to 7 years, 8 to 12 years, and 13 to 18 years. Measurement of decayed, missing, and filled teeth and scores for both deciduous and permanent dentition was done before and after the commencement of the dental treatment. Chisquare test and independent t-test were used for evaluating the level of significance.ResultsWhile comparing the patients in the two groups, maximum number of patients is present in the age group of 13 to 18 years. While comparing the indices’ score between the two study groups in various age intervals, no statistically significant results were obtained. Restorative treatment and dental extractions were the most common dental treatments that were seen at a higher frequency in the intellectual disability study group.ConclusionIn patients with mental retardation, a higher frequency of restorative treatment and extractions occurs as compared to healthy subjects of similar age group. Therefore, they require special attention regarding maintenance of their oral health.Clinical significanceSpecial attention should be given for maintaining the oral health of patients with special health care needs as compared to their physically and mentally normal counterparts.How to cite this articleAhuja R, Jyoti B, Shewale V, Shetty S, Subudhi SK, Kaur M.

ABSTRACT
Waardenburg syndrome (WS) is an inherited autosomal dominant genetic disorder presenting variable penetrance and expressivity, with an estimated prevalence of 1:42,000. Clinical characteristics of WS include lateral displacement of the internal eye canthus, hyperplasia of the medial portion of the eyebrows, prominent and broad nasal base, congenital deafness, pigmentation of the iris and skin, and white forelock. A 24-year-old male patient, previously diagnosed with WS, was referred to the Special Needs Dental Clinic of Sacred Heart University, Bauru, Brazil. Parents reported that the patient was experiencing self-mutilation, particularly in the oral region. He presented multiple congenital anomalies, including anophthalmia, mental retardation, low-set ears, and leg deformities. Clinical oral examination revealed hypodontia, abnormalities in dental morphology, extensive dental caries, periodontal disease, and fistulae. Extensive scars on the tongue, lips, and hands caused by self-mutilation were also observed. In accordance with his family and neurologist, full-mouth extraction under general anesthesia was performed, especially considering his severe self-aggressive behavior and the necessity to be fed with soft-food diet due to his inability to chew. After the surgical procedure, a significant reduction in the patient's irritability and gain of weight were reported in the followups of 30, 60, and 180 days.

Published: October 2016

ABSTRACT

Objectives
Entrapment of trauma patients in motor vehicle and other accidents is common. Frequently, Emergency Medical Services (EMS) personnel and firefighters are able to free the patient and initiate rapid transport to trauma centers. In rare circumstances, severe torso and extremity injuries combined with major entrapment may require complex rescue operations. These trauma patients spend the “Golden Hour” at the scene under difficult conditions. The objective of this review is to evaluate the role of the trauma surgeon leading the care at the scene of critically injured and entrapped trauma patients with possible need for surgical interventions.

Materials and methods
A 10-year review of all trauma surgeon to scene activations between 2005 and 2014 at the Ryder Trauma Center, an urban ACS Level 1 trauma center, was performed. An analysis of the trauma registry, individual cases, and surgical interventions was conducted.

Results
The University of Miami/Jackson Memorial Hospital (UM/JMH) Ryder Trauma Center and Miami Dade Fire Rescue have an established program in place for trauma surgeon to scene activations. During the study period, the on-call trauma surgeon was activated six times and traveled to the scene by air rescue helicopter four times, by ground in 1 case and in 1 case the patient expired before takeoff. One patient required on-scene amputation of an entrapped non-salvageable upper extremity. Two patients required on-scene amputation of bilateral lower mangled, entrapped extremities. One patient required a localized limb preserving surgical procedure to free him from entrapment. The incidence was 0.016% of 36,872 trauma alert activated patients evaluated at Ryder Trauma Center during the study period. Hemorrhagic shock, associated injuries, and long scene times were present in all patients. The survival of treated patients was 80%.

Conclusion
The need for on-scene amputations of nonsalvable extremities in entrapped trauma patients is rare. Experienced trauma surgeons should evaluate these patients and decide which interventions are necessary. All efforts should be made to salvage the limb. However, if the entrapped extremity appears nonsalvageable and the patient is in profound life-threatening shock requiring rapid transport, field amputation may be required. Policies, safety training and gear, supply kits, and partnerships with EMS are needed.

Automatic Identification of General Vector Error Correction Models
Authors: Arbués Ignacio , Ledo Ramiro , Matilla-García Mariano 
Published: October 2016

Abstract
There are a number of econometrics tools to deal with the different types of situations in which cointegration can appear: I(1), I(2), seasonal, polyno- mial, etc. There are also different kinds of Vector Error Correction models related to these situations. The authors propose a unified theoretical and practical framework to deal with many of these situations. To this aim: (i) they introduce a general class of models and (ii) provide an automatic method to identify models, based on estimating the Smith form of an autoregressive model. Their simulations suggest the power of the new proposed methodology. An empirical example illustrates the methodology.

Abstract. The chemical and physical speciation of atmospheric sulfur was investigated in ambient aerosol samples using a combination of sulfur near-edge x-ray fluorescence spectroscopy (S-NEXFS) and X-ray fluorescence (XRF) microscopy. These techniques were used to determine the composition and oxidation state of sulfur in common primary emission sources and ambient particulate matter collected from the greater Atlanta area. Ambient particulate matter samples contained two oxidation states: S0 and S+VI. Ninety-five percent of the individual aerosol particles (> 1 µm) analyzed contain S0. Linear combination fitting revealed that S+VI in ambient aerosol was dominated by ammonium sulfate as well as metal sulfates. The finding of metal sulfates provides further evidence for acidic reactions that solubilize metals, such as iron, during atmospheric transport. Emission sources, including biomass burning, coal fly ash, gasoline, diesel, volcanic ash, and aerosolized Atlanta soil, and the commercially available bacterium Bacillus subtilis, contained only S+VI. A commercially available Azotobacter vinelandii sample contained approximately equal proportions of S0 and S+VI. S0 in individual aerosol particles most likely originates from primary emission sources, such as aerosolized bacteria or incomplete combustion.

Published: October 2016

A colecistite acalculosa é uma inflamação da parede da vesicular biliar sem a presença de calculos, sendo responsável por 4 a 10% por cento dos casos de colecistite aguda. Objetivo: relatar um caso de CAA no serviço do HPP. Métodos: estudo restrospectivo de relato de caso. Discussão: Paciente de 13 anos, masculino, previamente hígido, admitido no HPP com quadro de dor em flanco direito, associada a náuseas, inapetência e diarréia líquida há 1 semana, com melhora parcial ao uso de analgésicos comuns (paracetamol e dipirona), porém com recorrência da dor. Realizou ultrassonografia de abdome total que mostrou colecistite aguda alitiásica e exames laboratorias com sinais inflamatórios. Paciente foi internado para tratamento conservador com antibioticoterapia. Apresentou resolução do quadro após 1 semana de tratamento, tendo alta hospitalar e sendo encaminhado para investigação ambulatorial. Conclusão: A CAA é uma patologia rara, de baixa prevalência na população geral e principalmente pediátrica. Deve-se suspeitar especialmente em pacientes críticos e hospitalizados por longos períodos, contudo, casos em pacientes previamente hígidos podem ser não tão infrequentes.

Published: October 2016

Abstract
The integration of a high-k oxide on graphene using atomic layer deposition requires an electrically reliable buffer layer. In this study, Y was selected as the buffer layer due to its highest oxidation ability among the rare-earth elements, and various oxidation methods (atmospheric, and high-pressure O2 and ozone annealing) were applied to the Y metal buffer layer. By optimizing the oxidation conditions of the top-gate insulator, we successfully improved the capacitance of the top gate Y2O3 insulator and demonstrated a large I

Published: October 2016

Abstract
Homoepitaxial single-crystal beta gallium oxide (β-Ga2O3) films were fabricated by the mist chemical vapor deposition method. The crystallinity of the films grown markedly depended on growth temperature, and the optimum growth temperatures were found to be 700–800 °C. Using unintentionally doped β-Ga2O3 films grown on Sn-doped β-Ga2O3(010) substrates, the fabrication of Schottky barrier diodes was demonstrated. Furthermore, we fabricated electrically conductive Sn-doped β-Ga2O3 films on semi-insulating Fe-doped β-Ga2O3(010) substrates. The carrier concentrations were between 1 × 1018 and 5 × 1020 cm−3. The Hall mobility was 45 cm2 V−1 s−1 at the carrier concentration of 1 × 1018 cm−3.

Abstract
The electron mobility in depletion-mode lateral β-Ga2O3(010) metal–oxide–semiconductor field-effect transistors (MOSFETs) with an n-channel formed by Si-ion (Si+) implantation doping was extracted using low-field electrical measurements on FET structures. An undoped Ga2O3 buffer layer protected the channel against charge compensation by suppressing outdiffusion of deep Fe acceptors from the semi-insulating substrate. The molecular beam epitaxy growth temperature was identified as a key process parameter for eliminating parasitic conduction at the buffer/substrate growth interface. Devices with a resistive buffer showed room temperature channel mobilities of 90–100 cm2 V−1 s−1 at carrier concentrations of low- to mid-1017 cm−3, with small in-plane mobility anisotropy of 10–15% ascribable to anisotropic carrier scattering.

Published: October 2016

Two cross-sectional studies investigated the effects of competition and cooperation with virtual players on exercise performance in an immersive Virtual reality (VR) cycle exergame. Study 1 examined the effects of: (1) self-competition whereby participants played the exergame while competing against a replay of their previous exergame session (Ghost condition), and (2) playing the exergame with a virtual trainer present (Trainer condition) on distance travelled and calories expended while cycling. Study 2 examined the effects of (1) competition with a virtual trainer system (Competitive condition) and (2) cooperation with a virtual trainer system (Cooperative condition). Post exergame enjoyment and motivation were also assessed.The results of Study 1 showed that the trainer system elicited a lesser distance travelled than when playing with a ghost or on one’s own. These results also showed that competing against a ghost was more enjoyable than playing on one’s own or with the virtual trainer. There was no significant difference between the participants’ rated enjoyment and motivation and their distance travelled or calories burned. The findings of Study 2 showed that the competitive trainer elicited a greater distance travelled and caloric expenditure, and was rated as more motivating. As in Study 1, enjoyment and motivation were not correlated with distance travelled and calories burned.ConclusionTaken together, these results demonstrate that a competitive experience in exergaming is an effective tool to elicit higher levels of exercise from the user, and can be achieved through virtual substitutes for another human player.
Brain-derived neurotrophic factor and schizophrenia
Authors: Gören Jessica L. 
Published: October 2016

Abstract
Schizophrenia is a severe disorder affecting approximately 1% of the population. Historically, alterations of dopaminergic function were considered the primary cause of schizophrenia. However, for many patients, drugs that alter dopaminergic function do not consistently lead to resolution of the symptoms of schizophrenia. Thus, there is an increased interest in pathophysiologic processes that result in altered neurodevelopment and plasticity associated with schizophrenia. Brain-derived neurotrophic factor (BDNF) is a neurotrophin involved in neurogenesis, synaptic plasticity, cognition, and neurotransmission. Genetic polymorphism, expression, and function of BDNF have been implicated in psychiatric diseases, including schizophrenia. This review discusses BDNF, its role in neurologic processes, and the evidence implicating BDNF in schizophrenia.
Evaluation of the use of low-dose quetiapine and the risk of metabolic consequences: A retrospective review

Published: October 2016

Abstract

Introduction:
Quetiapine fumarate is an atypical antipsychotic approved for the treatment of schizophrenia, major depressive disorder, and bipolar disorder. Due to the sedative effects observed at low doses, prescribers use quetiapine to aid patients with sleep disturbances. Current evidence has established that quetiapine can cause negative changes in metabolic parameters, but it is unknown if these consequences also occur at low doses. Due to the use of quetiapine for sleep, the purpose of this study is to identify if metabolic effects are also a risk with the use of low-dose quetiapine.

Methods:
Eligible subjects were identified through the Veterans Affairs electronic medical records as having an active prescription for quetiapine from June 30, 2012, through September 1, 2013. Subjects were then evaluated using inclusion and exclusion criteria for determination of study entrance. Descriptive statistics and t tests were utilized to identify clinical and statistical differences in outcomes.

Results:
A total of 403 subjects were included in the final analysis. The average dose of quetiapine was 116.8 mg and average duration of therapy was 44 months. Increases were observed in systolic blood pressure (+1.95 mmHg; P = .036), diastolic blood pressure (+1.97 mmHg; P = .001), body mass index (+0.52; P = .001), weight (+1.88 kg; P = .002), and fasting blood glucose (+6.71 mg/dL; P = .002). Conversely, a decrease in total cholesterol (−10.06 mg/dL; P &lt; .001) was recognized.

Discussion:
As a result of the findings, there may be negative metabolic consequences with the use of low-dose quetiapine. Routine prescribing of low doses for sleep as a first-line medication should be avoided.
Challenges in planet formation
Authors: Morbidelli Alessandro , Raymond Sean N. 
Published: October 2016

AbstractOver the past two decades, large strides have been made in the field of planet formation. Yet fundamental questions remain. Here we review our state of understanding of five fundamental bottlenecks in planet formation. These are the following: (1) the structure and evolution of protoplanetary disks; (2) the growth of the first planetesimals; (3) orbital migration driven by interactions between protoplanets and gaseous disk; (4) the origin of the Solar System's orbital architecture; and (5) the relationship between observed super‐Earths and our own terrestrial planets. Given our lack of understanding of these issues, even the most successful formation models remain on shaky ground.

Published: October 2016

AbstractZeolites are widely used in many commercial processes, mostly as catalysts or adsorbents. Understanding their intimate structure at the nanoscale is the key to control their properties and design the best materials for their ever increasing uses. Herein, we report a new and controllable fluoride treatment for the non‐discriminate extraction of zeolite framework cations. This sheds new light on the sub‐structure of commercially relevant zeolite crystals: they are segmented along defect zones exposing numerous nanometer‐sized crystalline domains, separated by low‐angle boundaries, in what were apparent single‐crystals. The concentration, morphology, and distribution of such domains analyzed by electron tomography indicate that this is a common phenomenon in zeolites, independent of their structure and chemical composition. This is a milestone to better understand their growth mechanism and rationally design superior catalysts and adsorbents.
