Background: Parkinson’s disease (PD) is a neurodegenerative condition that exerts a negative influence on postural control and mobility, predominantly among older adults, affecting mobility and increasing the risk of slipping, tripping and falls. Objectives: Determine the effectiveness of gait training with the aid of virtual reality on balance and gait in comparison to treadmill training and conventional gait training for subjects with PD. Methods/design: A prospective, randomized, controlled blind, clinical trial is proposed. The sample will comprise 45 individuals with Parkinson’s disease randomly allocated to three groups (Control: conventional gait training; Experimental I: treadmill training; and Experimental II: gait training involving virtual reality). Evaluations will be conducted on four occasions: 1) pre-intervention; 2) immediately after one session; 3) post-intervention; and 4) one month after last session. The evaluations will involve the Berg Balance Scale, Tinetti Test, Unified Parkinson’s Disease Rating Scale and Hoehn and Yahr Scale. The G-WALK (BTS) inertial sensor will be used for the evaluation of spatiotemporal gait variables, the Timed Up and Go test and the Six-Minute Walk Test. Training will involve 20-minute sessions held three times per week for four consecutive weeks. The results will be analyzed statistically by two-way ANOVA for the data with parametric distribution or Friedman’s two-way ANOVA for non-parametric data (α<0.05). Conclusion: The proposed study will compare gait conventional training, treadmill training and training with virtual reality with regard to improvements in gait and balance in patients with PD. The results will be published and will contribute evidence on the use of these interventions for individuals with PD.

This article centers on the historical actors doña Marina and Jerónimo de Aguilar and how modern authors of fiction have used them as fictional characters to reinterpret traditional and formal history. The authors follow the tradition of the cronistas that forms the primary basis of historical resources on the conquista, of using partial and subjective narrative to rebuild the reputation of historical actors. In both novels bilingual identity is fundamental in reclaiming the human and sympathetic nature of the historic actors despite their contributions to the success of the conquista.

O dinamismo econômico das regiões é um fator bastante decisivo para a não estagnação de sua economia. Baseado nisso, as regiões tem procurado desenvolver-se cada vez mais e, além do setor urbano, a área rural vem procurando contribuir com essa dinâmica, como exemplo, o aumento da participação no setor de serviços. Melhorar rendimentos e aumentar o poder aquisitivo é uma preocupação crescente na vida das famílias, tanto urbana, como rurais. No setor rural, a pobreza e a desigualdade vêm de certa forma, quando não estagnadas, diminuindo. Boa parte dessa melhoria na renda pode ser considerada por meio do avanço do setor de serviços, abrindo espaço para as famílias tornarem-se pluriativas.  Assim, faz-se necessário diversificar a forma de obtenção de renda. Atualmente, as famílias passaram a constituir uma nova classificação: As chamadas pluriativas. O objetivo deste trabalho consiste em examinar a nova dinâmica da região Nordeste, fazendo uma análise no setor de serviços, paralelo ao novo rural, demonstrando ainda, como essa nova dinâmica influencia positivamente a região por meio da diminuição ou estagnação da pobreza e da desigualdade. A metodologia utilizada consiste em uma revisão bibliográfica, de cunho exploratório, concernente à temática abordada explicitando e caracterizando respectivamente, pluriatividade, o novo rural, pobreza e desigualdade, fazendo uso dos índices de pobreza FGT, de desigualdade de Gini. Os resultados demonstram que existe uma nova dinâmica na Região Nordeste, advinda do aumento e da transformação do setor de serviços, que age como propulsor da mudança do rural, entendendo que este setor não pode ser considerado apenas agrícola. Portanto, essa modificação vem ajudando a transformar este cenário.

No presente artigo apresenta-se uma reflexão exploratória sobre a inclusão da educação financeira no currículo da educação básica, a partir da análise de 24 projetos político-pedagógicos de escolas estaduais de ensino fundamental de alguns estados brasileiros, entre os anos de 2010 a 2015.  Os respectivos projetos foram coletados na internet. Foi realizada a análise de conteúdos dos respectivos documentos, observando-se três unidades analíticas: prática pedagógica da escola, objetivos políticos-pedagógicos da escola e projetos ou programas voltados para a educação financeira. Identificou-se que nenhum dos projetos avaliados prevê a educação financeira, embora 87,50% prevejam práticas interdisciplinares ou transversais e 66,67% tenham como objetivo geral e ou específico preparar os alunos para a vida. Concluiu-se, à luz da conjugação dessas informações com a revisão de literatura que privilegiou a apresentação de estatísticas sobre o comportamento financeiro do brasileiro, a dinâmica do programa da OCDE para a promoção de estratégias nacionais de educação financeira e conceitos de Finanças Comportamentais, que há limitações na forma como o Estado difunde a Estratégia Nacional de Educação Financeira, até o momento apresentada como prática interdisciplinar que pode ser adotada voluntariamente pela instituição de ensino.

Keeping Abreast of Developments in the Cancer Wars: A View from the Front
Authors: Baenziger Nancy L.
Published: November 2017

Cancer somehow lends itself to military analogies, perhaps because of its status as a threat to life itself. We've declared war on cancer over several decades, viewing cancer as a cell going rogue, dividing uncontrollably, and ultimately breaking through local boundaries to spread. Less well known, but critically relevant to the health care impact of questioning authority, is the war within the breast cancer management community, among those studying molecular and cellular targets in breast cancer biology and those managing the human targets that represent cancer's toll. This article outlines current concepts and controversies about breast cancer, presenting a bio/sociological basis and a mental toolkit for thinking about and coping with this conflict.
Interprofessional Collaboration between Mental Health Counselors and Nurses
Authors: Ghassemi Akhtar Ebrahimi
Published: November 2017

The continuous and rapid evolution of medical technology and the complexity of delivering person-centered care in the 21st century calls for collaboration among health care professionals. Global health now “involves many disciplines within and beyond the health sciences and promotes interdisciplinary collaboration; and is a synthesis of population-based prevention with individual-clinical care” (Koplan et al., 2009, p. 1995). The need for mental health practitioners to work in interprofessional contexts requires graduate and postgraduate programs to incorporate interprofessional education into their student training. This article focuses on an approach to interprofessional education for students in mental health nursing and counseling.

Published: November 2017

Purpose

This descriptive field study examines processes used to evaluate simulation for senior-level Bachelor of Science in Nursing (BSN) students in a capstone course, discusses challenges related to simulation evaluation, and reports the relationship between faculty evaluation of student performance and National Council Licensure Examination for Registered Nurses (NCLEX-RN) first-time passing rates.

Methods

Researchers applied seven terms used to rank BSN student performance ( n = 41, female, ages 22–24 years) in a senior-level capstone simulation. Faculty evaluation was correlated with students ‘NCLEX-RN outcomes.

Results

Students evaluated as “lacking confidence” and “flawed” were less likely to pass the NCLEX-RN on the first attempt.

Conclusions

Faculty evaluation of capstone simulation performance provided additional evidence of student preparedness for practice in the RN role, as evidenced by the relationship between the faculty assessment and NCLEX-RN success.

Implications

Simulation has been broadly accepted as a powerful educational tool that may also contribute to verification of student achievement of program outcomes and readiness for the RN role.

CARDIOPROTECTIVE EFFECTS OF CURCUMIN AGAINST DIABETES AND NICOTINE-COMBINED OXIDATIVE STRESS
Authors: Ibrahim Zein Shaban , Soliman Mohamed Mohamed , Mahmoud Shawky , Shukry Mustafa
Published: November 2017

Background: Diabetic cardiomyopathy (DCM) develop through oxidative stress-induced myocardial cell apoptosis that cause cardiac tissue damage resulting in hemodynamics disturbance while Cigarette Smoking (CS) is associated with a significant increase in the risk of recurrent ventricular tachyarrhythmia in ischemic and non-ischemic cardiomyopathy patients caused by oxidative stress. Curcuma longa extract (curcumin) is known to protect against hyperglycemia-induced oxidative stress. This brought in mind to investigate the probability of the crcumin ability to ameliorate the combined diabetes and smoking induced oxidative stress caused DCM

Materials and Methods: Diabetic rats were administered nicotine to investigate the effect of the combined oxidative stress of diabetes and nicotine. Moreover, curcumin was administered to examine its protective effect on possible oxidative stress induced diabetes and nicotine.

Results: Nicotine administration in a dose of 1.5 mg/kg to diabetic rats increased the oxidative stress. This occurs through elevation of plasma nitric oxide (NO) and upregulation of cardiac tissue inducible nitric oxide synthase (iNOS) and Endothelin-1 mRNA expressions, in addition to elevation of plasma triglycerides (TG), and LDL and reduction of HDL levels. Nicotine administration also reduced the cardiac tissue protective mechanism through reduction of plasma superoxide dismutase (SOD), cardiac tissue Erythropoietin (EPO), vascular endothelial growth factor (VEGF) isoforms and VEGF receptor mRNA expressions. These combined oxidative stresses were manifested by elevation of the plasma cardiac markers troponin I and creatine kinase (CK-MB). Supplementation of curcumin prevented the diabetic and nicotine-induced oxidative stress through reduction of plasma NO and iNOS and Endothelin-1 mRNA expressions to their control levels and elevation of plasma SOD and upregulation of cardiac tissue Erythropoietin (EPO), vascular endothelial growth factor (VEGF) isoforms and VEGF receptor mRNA expressions. This curcumin protective effect of the cardiac tissue was manifested by normalization of the plasma cardiac marker troponin I and CK-MB.

Conclusion: These results strongly confirmed that curcumin protected cardiac tissues from the combined oxidative stress induced by diabetes and nicotine.

Published: November 2017

Background: Current chemotherapeutic agents for the treatment of African trypanosomiasis have become largely ineffective, necessitating the search for alternative compounds. The objective of this study was to evaluate in vitro anti-trypanosomal activities of methanol extracts of parts of Azadirachta indica against Trypanosoma brucei rhodesiense, Trypanosoma brucei brucei and Trypanosoma evansi and establish the in vivo efficacy of the most active extract.

Materials and methods: Maceration of powdered leaves, stem bark and root bark of the plant in methanol afforded three extracts. In vitro assays were carried out with the extracts on the three trypanosome strains in 96-well microtitre plates at concentration ranges of 4000 - 1000μg/ml. The most active extract was assayed in vivo using Trypanosoma brucei rhodesiense infected Swiss albino mice at doses of 100, 200 and 400 mg/kg body weight. Melarsoprol and suramin served as positive controls. The infected untreated group served as the negative control. Parasitaemia levels, packed cell volume, body weight changes and mean survival period of all groups were monitored throughout the experimental period.

Results: Methanol extract of the stem bark of A.indica was most active in vitro against all the three trypanosome strains (MIC values of 9.93±1.88, 16.25±0.92 and 9.97±0.44μg/ml for T. b. rhodesiense, T. b. brucei and T. evansi, respectively). The extract showed optimum activity at 400 mg/kg and was comparable to the positive control groups. Parasitaemia levels were kept at a significantly low level (p < 0.05) by the extract compared to the negative control. Notably, there was no significant difference (p>0.05) in mean survival time of mice treated with the extract at 400 mg/kg and the positive controls.

Conclusion: In vitro and in vivo anti-trypanosomal activities of the methanol extract of A. indica stem bark could be attributed to the presence of constituents of moderate polarity.

Exploring Alternative Management Options for Multiyear Perennial Ryegrass Seed Production in Northern Minnesota
Authors: Heineck Garett , Watkins Eric , Ehlke Nancy Jo
Published: November 2017

Perennial ryegrass (Lolium perenne L.) is grown as a biennial when produced for seed in Minnesota; however, producers desire multiyear seed production. One approach to achieving multiyear seed production could be through improved management practices. In particular, plant growth regulators (PGRs) and fall residue management could help overcome several obstacles hindering multiyear seed production in northern climates. We assessed the impact of fall residue management practices and various PGRs after first‐year harvest on winter survival and second‐year seed yield of perennial ryegrass grown in northern Minnesota. The experiment was conducted for three trial years from 2013 to 2016 in second‐year perennial ryegrass seed production swards. Three fall residue management treatments and five fall‐applied PGR treatments were evaluated in a split‐plot design. Fall‐applied PGRs had no effect on second‐year seed yield and minimal effects on winter survival. Managing residue by open‐burning consistently resulted in significantly higher second‐year seed yields than in the no residue removal control (1064 vs. 680 kg ha−1, respectively). Open‐burning and baling and mowing residue resulted in similar seed yields in 2 out of 3 yr, and both increased yields compared with no residue removal. Winter survival was only moderately affected by residue management, was highly dependent on year, and had an impact on mean seed yields across treatments. This indicates that winter survival and fall residue management are both important in maintaining multiyear seed yield in Minnesota.
Accounting for Calcareous Concretions in Calcic Vertisols Improves the Accuracy of Soil Hydraulic Property Estimations
Authors: Gu Feng , Ren Tusheng , Li Baoguo , Li Lujiu
Published: November 2017

Core Ideas

Calcareous concretions (CCs) could maintain a considerable amount of water and the water content of CCs decreased with an increase in CC sizes.

The addition of CCs to soils changed the WRC and the pore distribution of soils significantly.

The available water content (AWC) of soil–CC mixtures decreased when the CC content increased.

A linear equation, which included CC content and CC water content, was proposed to estimate the AWC of soils containing CCs accurately.

The soil water retention curve (WRC) is one of the most important properties in soil hydraulic studies. Current studies normally focus on fine soils, ignoring the water‐holding capacity of coarse fragments (>2 mm) and their effects on soil available water content (AWC). Calcareous concretions (CC) are coarse inclusions distributed widely in soils around the world. This study was conducted to quantify the effects of the proportion and size of CCs on the soil WRC and AWC of a calcic vertisol. The WRCs of CCs were measured using the sand box and ceramic plate method, and the WRCs of fine soils and soil–CC mixtures of various sizes (2–5, 5–8, and 8–30) and proportions (5, 10, 15, and 30% on a total mass basis) of CC were determined with the centrifuge method. The WRCs were fitted with the van Genuchten equation. The results showed that CCs retained a considerable amount of water. The saturated water contents of CCs of 2‐ to 5‐, 5‐ to 8‐ and 8‐ to 30‐mm were 0.251, 0.220, and 0.196 cm3 cm–3, respectively. The addition of CCs changed the WRC and pore distribution of soils significantly. The AWC of soil–CC mixtures decreased with increasing CC content. A linear equation, which included the fraction of CCs and water content in CCs, was proposed to estimate the AWC of soils containing CCs accurately. Accounting for CCs in the calcic vertisol improved the accuracy of soil hydraulic property estimations.
Sulfur Containing Acridine Derivatives in Preclinical Studies with Cancer Cell Lines
Authors: Othman Salem , Kozurkova Maria
Published: November 2017

Background:

The possible use of acridines as anticancer agents was first considered
in the 1920´s. Since then, a large number of acridine drugs have been tested as antitumour
agents, including compounds containing sulphur on the acridine chromophore. In this review,
we will discuss recent studies which have investigated the anticancer activity of this class of
acridine derivatives.

Methods:

We present the results both of our own decade-long research and also of existing
research literature into the anticancer activity of acridine derivatives containing sulphur. The
evidence of specific tumor-cell killing properties displayed by these compounds suggest the
potential of using such molecules as anticancer therapeutics.

Results:

During the last decade, a number of acridine analogs have been developed by modifying
the position and the nature of the substituent on the acridine core. In this paper, we published
results on the anticancer activity of acridine derivatives containing sulfur (acridine thioureas,
acridine thiazolidine/thiazoidinone, and acridine thiosemicarbazones/ thiosemicarbazides).
In cancer chemotherapy, the mechanism of the drugs is complex, although the study of
the anticancer activity of acridines has yielded exciting results.

Conclusion:

In this review we have summarized recent literature on the anticancer activity of
acridine derivatives containing sulfur. A considerable amount of published data suggests that
these compounds exhibit promising anticancer activity against selected cancer cell lines. The
obtained results can be helpful in the development of new pharmaceutical agents.
Electrochemical Determination of Rivastigmine Hydrogen Tartrate at β-Cyclodextrin/Multi-Walled Carbon Nanotubes Modified Electrode
Authors: Kılıçyaldır Bugçe , Avan Asiye Aslıhan , Güçlü Kubilay , Özyürek Mustafa , Filik Hayati
Published: November 2017

Background:

Electrochemical techniques can easily be adopted to solve many problems of pharmaceutical interest. The implementation of electroanalytical methods in the assay of pharmaceutical formulations has increased greatly. Nowadays, owing to the critical importance of electron transfer and surface properties, chemically modified electrodes have been employed in electrochemical sensors. The chemically modified electrode is one of the most popular electroanalytical sensors and used in several applications.

Methods:

In this work, a β-cyclodextrine/multi-walled carbon nanotubes (β-CD/MWCNTs) composite modified glassy carbon electrode (GCE) was produced and applied to the detection of Rivastigmine hydrogen tartrate (RVT) in pharmaceutical formulations. The voltammetric feature of RVT at this β- CD/MWCNTs modified electrode was evaluated using cyclic voltammetry and square wave voltammetry.

Results:

The β-cyclodextrin and multi-walled carbon nanotubes modified glassy carbon electrode displayed good electrocatalytic activity in the oxidation of rivastigmine hydrogen tartrate with relatively high sensitivity, stability and lifetime. The calibration graph of the analyte was linear over the range 10- 1500 µM with two linear segments and the detection limit was obtained as 2.0 µM (S/N=3). The results showed that the electrochemical sensor has good sensitivity and selectivity.

Conclusion:

The β-CD/MWCNTs modified electrode displayed a high electrochemical activity and good sensitivity toward the oxidation of RVT. Compared with the bare MWCNTs coated sensor, the response of analyte increased soundly and the response potential of target analyte shifted negatively. The results indicated that the β-CD/MWCNTs film coated electrode had good catalysis to the voltammetric oxidation of RVT. The prepared sensor was applied to determine RVT in pharmaceutical samples with satisfactory yields. The outcomes indicate that β-CD/MWCNTs coated electrode is a safe choice for the detection of RVT.

BACKGROUND

The early diagnosis of melanoma is associated with decreased mortality. The smartphone, with its apps and the possibility of sending photographs to a dermatologist, could improve the early diagnosis of melanoma.

OBJECTIVE

The aim of our review was to report the evidence on (1) the diagnostic performance of automated smartphone apps and store-and-forward teledermatology via a smartphone in the early detection of melanoma, (2) the impact on the patient’s medical-care course, and (3) the feasibility criteria (focusing on the modalities of picture taking, transfer of data, and time to get a reply).

METHODS

We conducted a systematic search of PubMed for the period from January 1, 2007 (launch of the first smartphone) to November 1, 2017.

RESULTS

The results of the 25 studies included 13 concentrated on store-and-forward teledermatology, and 12 analyzed automated smartphone apps. Store-and-forward teledermatology opens several new perspectives, such as it accelerates the care course (less than 10 days vs 80 days), and the related procedures were assessed in primary care populations. However, the concordance between the conclusion of a teledermatologist and the conclusion of a dermatologist who conducts a face-to-face examination depended on the study (the kappa coefficient range was .20 to .84, median κ=.60). The use of a dermoscope may improve the concordance (the kappa coefficient range was .29 to .87, median κ=.74). Regarding automated smartphone apps, the major concerns are the lack of assessment in clinical practice conditions, the lack of assessment in primary care populations, and their low sensitivity, ranging from 7% to 87% (median 69%). In this literature review, up to 20% of the photographs transmitted were of insufficient quality. The modalities of picture taking and encryption of the data were only partially reported.

CONCLUSIONS

The use of store-and-forward teledermatology could improve access to a dermatology consultation by optimizing the care course. Our review confirmed the absence of evidence of the safety and efficacy of automated smartphone medical apps. Further research is required to determine quality criteria, as there was major variability among the studies.
Too Important to Ignore: Leveraging Digital Technology to Improve Chronic Illness Management Among Black Men (Preprint)

UNSTRUCTURED

Health disparities associated with chronic illness experiences of black men demonstrate widespread, systematic failures to meet an urgent need. Well-established social and behavioral determinants that have led to health disparities among black men include racism, discrimination, and stress. While advocacy work that includes community-engagement and tailoring health promotion strategies have shown local impact, evidence shows the gaps are increasing. We suspect that failure to reduce current disparities may be due to conventional public health interventions and programs; therefore, we submit that innovative interventions, ones that embrace digital technologies and their ability to harness naturally occurring social networks within groups, like black men, have particular importance and deserve attention. This commentary characterizes the current literature on chronic illness among black men as well as health interventions that use digital technology, to build a case for expanding research in this area to reduce the overwhelming burden of chronic illness among black men.
Generación Colaborativa de conocimiento:
Authors: Kniffki Johannes
Published: November 2017

El presente texto apunta a la cuestión „como se logra que los diferentes y diferenciadas formas de saberes y conocimientos que se encuentren en un momento de colaboración en el campo socio-politico, se retroalimentan de tal manera que la acción socio-política sea apropiada al tema y que tenga así un impacto político y transformador en el mismo campo.“ Para acercarse a esta pregunta se presenta una reflexión conceptual de una maestría que se iniciara implementar al mismo tiempo en Berlín, Alemania y Oaxaca, México. Esta propuesta de estudio superior parte en su esencia de lo que se quiere decir con el término de ‘investigación–acción–participativa’. Se propone que ésta puede fundamentarse tanto en la crisis de las ciencias sociales y proponiendo que se sustituye el ‘nacionalismo metodológico’ y el ‘individualismo metodológico’ por lo del ‘espacio social’ haciendo hincapiés en la sociología de conocimiento y el derivado del ‘mundo social’. Esto tiene que ser encamado en una ética que permite que los conocimientos de todos los participantes de un proceso participativo de investigación-acción sea validado como equivalente para así generar colaborativamente un conocimiento que es su esencia es pedagógico y por ende político.
As (cada vez mais) novas tecnologias inseridas no cotidiano escolar sob a ótica docente

Published: November 2017

Este trabalho objetivou desvelar a percepção e/ou o entendimento docente sobre os atuais desafios para a utilização novas tecnologias em práticas pedagógicas no cotidiano escolar. Para tanto, utilizou-se da técnica da análise do conteúdo preconizada por Bardin (2007) como metodologia de análise aplicada às respostas de 07 professores atuantes em uma escola da rede pública de ensino em São Paulo/SP. A interpretação e discussão dos dados permitiu-nos concluir que a inovação nas práticas pedagógicas, segundo os entrevistados ainda depende, intrinsicamente, do apoio e de ações governamentais que objetivem tal finalidade. Ainda: os resultados apontam para uma falsa percepção docente de que as novas tecnologias não são capazes de promover mudanças nas práticas pedagógicas.

The effects of ultrasound power and frequency on the yield of total extractive substances (TES), total phenolic content (TPC), total flavonoid content (TFC) and antioxidant activity (AOA) of fresh houseleek leaves extracts obtained by direct ultrasound-assisted extraction (DUAE) were studied. Preliminary extraction of plant material was performed using methanol, acetone and 2-propanol by Soxhlet extraction. It was found that maximum TES yield could be obtained by methanol extraction (2.91?0.02), followed by acetone and 2-propanol with a TES yield of 2.32?0.01 and 2.01?0.03 g per 100 g of fresh plant material, respectively. In the fresh houseleek leaves extracts obtained by DUAE and methanol as the chosen solvent, TPC, TFC and AOA were in the ranges of: 40.5?85.9 mg gallic acid/g dry extract, 12.7?19.3 mg rutin/g dry extract and 24.6?108.2?g/ml, respectively. The results showed that the increase in the ultrasound power and extraction time have positive and significant (p < 0.05) effects on the TPC, TFC and AOA, while the increase in the ultrasound frequency leads to a decrease in the TPC, TFC and AOA of the extracts. A chromatographic analysis of crude extract identified the following: kaempferol 3-O-(6??-O-malonylglucoside)- 7-O-glucosyde, kaempferol 3-O-glucoside-7-O-rhamnoside, luteolin 5-O-(6??-O-malonylglucoside), kaempferol 3-O-(6??-O-acetylglucoside)-7-O-rhamnoside, genkwanin 5-O-glucoside, luteolin 5-O-(6??-O-malonylglucoside), kaempferol 3-O-(6??-O-malonylglucoside), kaempferol 3-O-rhamnoside, quercetin, genkwanin 4?-O-glucoside and hyperoside.

Published: November 2017

Spider silk fibers, collected from Pholcus Phalangioides spider were used as a template for obtaining magnesium oxide (MgO, periclase) as well as magnesium hydroxide (Mg(OH)2, brucite) fibers. Magnesium oxide fibers were obtained in a simple manner by heat induced decomposition of magnesium salt (MgCl2) in the presence of the spider silk fibers, while magnesium hydroxide fibers were synthesized by hydration of MgO fibers at 50, 70 and 90 ?C, for 48 and 96 h. According to Scanning electron microscopy (SEM), dimensions of spider silk fibers determined the dimension of synthesized MgO fibers, while for Mg(OH)2 fibers, the average diameter was increased with prolonging the hydration period. The surface of Mg(OH)2 fibers was noticed to be covered with brucite in a form of plates. X-Ray diffraction (XRD) analysis showed that MgO fibers were single-phased (the pure magnesium oxide fibers were obtained), while Mg(OH)2 fibers were two- or single-phased brucite depending on incubation period, and/or incubation temperature.

Objective:

This trial evaluates the impact of psychosocial and esthetic self-perceptions of patients undergoing nonvital tooth bleaching using the walking bleach technique. We also assessed the clinical effectiveness of bleaching tooth discoloration.

Methods:

Fifty volunteers with nonvital tooth discoloration were enrolled. Teeth were randomized into two groups: 35% hydrogen peroxide (n=25) and 37% carbamide peroxide (n=25). Intracoronal bleaching was performed over four sessions using the walking bleach technique. Tooth color was evaluated at each session to measure total color variation. The shade guide was arranged from highest (B1) to lowest (C4) values to assess the color and calculate the color change in the number of shade guide units. Subjective and objective assessments were compared with the tooth counterpart. Esthetic self-perception and psychosocial factors were assessed before and after treatment.

Results:

Color change was 15.48<5.17 for hydrogen peroxide and 14.02<4.85 for carbamide peroxide. There was no significant difference at any time point (p>0.05) except at sessions 3 and 4 (p<0.05). Overall, whitened teeth values were similar to those of counterpart teeth (p>0.05). There was a decrease in Oral Health Impact Profile and Psychosocial Impact of Dental Esthetics questionnaire scores after treatment compared with baseline (p<0.05).

Conclusion:

The walking bleach technique was highly effective on nonvital teeth and had a positive effect on self-esthetic perception and psychological impact for the patients.
