Background: The aim of this longitudinal study is to verify changes in the oral health‐related quality of life of patients 180 days after treatment of dentin hypersensitivity (DH) with laser and cyanoacrylate.Methods: This clinical, controlled, randomized, double‐masked trial used a split‐mouth design, and quadrants were randomized to receive either laser or cyanoacrylate treatments. All patients received both treatments. The study included 62 patients aged 12 to 60 years (mean: 31.4 years) in whom a total of 432 teeth were treated. Quadrants were randomly distributed into two groups: cyanoacrylate (n = 218 teeth) or laser (n = 216 teeth) treatment. DH was evaluated with air and cold stimuli at 24 hours, 30, 90, and 180 days after treatment. The Oral Health Impact Profile (OHIP‐14) questionnaire was applied at baseline and 180 days after treatment.Results: There were statistically significant differences in the following OHIP‐14 subscales before and after treatment: physical pain (P = 0.002), psychologic discomfort (P <0.001), psychologic disability (P = 0.003), social disability (P = 0.01), and total score (P <0.001). At the end of the study, 80.6% of participants reported an improvement in their condition.Conclusion: There was a reduction in the impact of DH on the quality of life of study participants after interventions with laser and cyanoacrylate.

Background: It has been hypothesized that zirconia might have a reduced bacterial adhesion compared with titanium; however, results from experimental studies are rather controversial. The aim of the present study is to compare biofilm formation on zirconia and titanium implant surfaces using an in vitro three‐species biofilm and human plaque samples.Methods: Experimental disks made of titanium (Ti) or zirconia (ZrO2) with a machined (M) or a sandblasted (SLA) and acid‐etched (ZLA) surface topography were produced. An in vitro three‐species biofilm or human plaque samples were applied for bacterial adhesion to each type of disk, which after 72 hours of incubation was assessed using an anaerobic flow chamber model.Results: Zirconia showed a statistically significant reduction in three‐species biofilm thickness compared with titanium (ZrO2‐M: 8.41 μm; ZrO2‐ZLA: 17.47 μm; Ti‐M: 13.12 μm; Ti‐SLA: 21.97 μm); however, no differences were found regarding three‐species‐biofilm mass and metabolism. Human plaque analysis showed optical density values of 0.06 and 0.08 for ZrO2‐M and ZrO2‐ZLA, and values of 0.1 and 0.13 for Ti‐M and Ti‐SLA, respectively; indicating a statistically significant reduction in human biofilm mass on zirconia compared with titanium. Additionally, zirconia revealed a statistically significant reduction in human plaque thickness (ZrO2‐M: 9.04 μm; ZrO2‐ZLA: 13.83 μm; Ti‐M: 13.42 μm; Ti‐SLA: 21.3 μm) but a similar human plaque metabolism compared with titanium.Conclusion: Zirconia implant surfaces showed a statistically significant reduction in human plaque biofilm formation after 72 hours of incubation in an experimental anaerobic flow chamber model compared with titanium implant surfaces.

Published: October 2016

Background: Different materials have been investigated for renewal of lost supporting periodontal structures and tested for furcation defect treatment. Platelet‐rich fibrin (PRF) is a pool of growth‐promoting factors and cytokines that promote bone regeneration and maturation of soft tissue. Alendronate (ALN), an influential member of the bisphosphonate group, is known to enhance osteoblastogenesis and inhibit osteoclastic bone resorption, thus promoting tissue regeneration. This randomized trial was done to assess effectiveness of PRF and 1% ALN gel combination in mandibular degree II furcation defect treatment in comparison with PRF and access therapy alone.Methods: Seventy‐two mandibular molar furcation defects were treated with either access therapy alone (group 1), access therapy with PRF (group 2), or access therapy with PRF and 1% ALN (group 3). Plaque index, modified sulcus bleeding index, probing depth (PD), relative vertical attachment level (RVAL) and relative horizontal attachment level (RHAL), and intrabony defect depth were recorded at baseline and 9 months postoperatively. Radiographically, defect fill, assessed in percentage, was evaluated at baseline, before surgery, and 9 months post‐therapy.Results: Group 3 showed greater PD reduction and RVAL and RHAL gain when compared with groups 1 and 2 postoperatively. Moreover, group 3 sites showed a significantly greater percentage of radiographic defect fill (56.01% ± 2.64%) when compared with group 2 (49.43% ± 3.70%) and group 1 (10.25% ± 3.66%) at 9 months.Conclusions: Furcation defect treatment with autologous PRF combined with 1% ALN gel results in significant therapeutic outcomes when compared with PRF and access therapy alone. Combining ALN with PRF has potential for regeneration of furcation defects without any adverse effect on healing process.

Published: October 2016

Background: Although periodontal pathogens show a strong association with development of atherosclerosis, little is known about how a microorganism contributes to disease onset and progression. Oxidation of low‐density lipoprotein (LDL) is a major risk factor of atherogenesis. The principal objective of this study is to evaluate the ability of peptide 19 (Pep19) of Porphyromonas gingivalis (Pg) heat shock protein (HSP) as a potent inducer of LDL oxidation, and a secondary objective is to compare this ability with that of Pep19 from different bacteria.Methods: HSP60, Pep14, and Pep19 from Pg and THP‐1 monocytes were cultured, and the extent of LDL oxidation induced by each peptide was evaluated by an assay for thiobarbituric acid‐reactive substances (TBARS). Pep19 and HSP60 from Chlamydia pneumoniae and Mycobacterium tuberculosis were also cultured with THP‐1 monocytes and evaluated by the TBARS assay. After incubation of macrophages with LDL and peptides from Pg, Oil Red O staining was performed for examination of foam cells, macrophages that took up the oxidized LDL.Results: Monocyte‐mediated native‐LDL oxidation under the influence of Pep19 or HSP60 from Pg was significantly stronger than oxidation induced by the counterpart Pep19 or HSP60 from C. pneumoniae or M. tuberculosis. Pep19 from Pg HSP60 showed a stronger ability to induce LDL oxidation than did Pep14 from Pg HSP60.Conclusion: These results suggest Pep19 from Pg HSP60 has a distinct ability to induce native‐LDL oxidation as a plausible mechanism by which this peptide may drive epitope spreading to the neoantigen, i.e., oxidized LDL, in the pathogenesis of atherosclerosis.

Experiencia de familiares de enfermos con cáncer terminal respecto a las decisiones al final de la vida
Authors: Ordóñez Vázquez Norma Alicia , Monroy Nasr Zuraya 
Published: October 2016

Introducción: La experiencia de los familiares que toman el rol de cuidadores primarios, en el proceso de una enfermedad terminal como el cáncer, proporciona información acerca de la toma de decisiones al final de la vida. El objetivo de este trabajo fue conocer desde la experiencia del familiar del enfermo quién toma las decisiones al final de la vida y cómo afectan estas decisiones al enfermo si no se considera su autonomía.Método: Tipo de estudio: Investigación de corte cualitativo que parte del paradigma hermenéutico fenomenológico. Se aborda desde la postura fenomenológica porque esta permite conocer la percepción que tienen las personas del mundo en el cual viven y el significado que le dan. Además se centra en la experiencia de vida de las personas, en este caso en la experiencia de los familiares de enfermos terminales. Se utilizó la entrevista semiestructurada. Participantes: Cuidadores primarios y familiares de enfermos con cáncer terminal que fueron atendidos en hospitales de la ciudad de México.Procedimiento: Se elaboró una guía de entrevista semiestructurada. Se realizaron 11 entrevistas de las cuales ocho formaron díadas cuidador/familiar. Las tres restantes se realizaron a cuidadores. Seis entrevistas se llevaron a cabo en un espacio de un hospital de tercer nivel y cinco en espacios públicos. Se utilizó el análisis temático y el método de van Manen. Resultados: La experiencia de los familiares muestra por una parte que las decisiones fueron tomadas por el enfermo (plano autónomo), aunque existieron algunos casos en los que él no tomó la decisión, en el momento final, los familiares fueron los que tuvieron que asumir la responsabilidad de tomar decisiones, dependiendo de cómo se iba presentando el proceso de enfermedad (plano dependiente). Es importante resaltar que en los casos estudiados no siempre existió adecuada comunicación médico-paciente. Además, desde la perspectiva fenomenológica, se observó que las personas pudieron darse cuenta de su existencia y su mundo a partir de la enfermedad, como evento desestabilizador.Discusión o Conclusión: En este trabajo se observó que el respeto a la autonomía del enfermo es fundamental para la toma de decisiones al final de la vida. Si no cuenta el enfermo o la familia con la información acerca del diagnóstico y/o pronóstico, es muy difícil que puedan tomar decisiones y evitar una muerte con sufrimiento y malestar. Como diversas investigaciones lo han señalado, es necesario que el médico hable con los pacientes acerca de la situación en la que se encuentran para que puedan enfrentarse mejor a la enfermedad y prepararse para la muerte. En los casos que se estudiaron, existió poca o nula comunicación médico-paciente, por lo que hace falta mayor capacitación en esta área.
Factors influencing the production of Hidrogen by fermentative processes
Authors: Poleto Liliane , Magrini Flaviane Eva , Beal Lademir Luiz , Paesi Suelen Osmarina 
Published: October 2016

<p><strong>Abstract - </strong>Growing concern about finding suitable replacements for fossil fuels has encouraged the search for new clean energy production processes. Hydrogen has been highlighted as an ideal form of energy because this molecule does not contribute to the greenhouse effect and it possesses a high calorific value. The microbiological production of this gas is a process that can become sustainable from social, environmental and economic points of view once the microorganisms isolated from the environment can use agro-industrial wastes as substrate. Various microorganisms are described in the literature as producers of hydrogen from several types of substrates, especially species from the genera <em>Clostridium </em>and <em>Enterobacter</em>. However, various scientific factors and fermentation operating conditions that will steer the metabolic pathway to the production of hydrogen should be analyzed. The objective of this work is to contribute to the state of the art by reviewing recent studies involving the microbiological production of hydrogen and the main aspects involved in biotechnological process.</p>

Published: October 2016

Objective:
The aim of this study was to investigate the relationship between the attentional coping styles (monitoring and blunting) of rheumatoid arthritis (RA) and osteoarthritis (OA) patients and: (a) receipt of medication information; (b) receipt of conflicting medication information; (c) ambiguity aversion; (d) medication-related discussions with doctors and spouse/partners; and (e) medication adherence.

Method:
A sample of 328 adults with a self-reported diagnosis of arthritis (RA n=159; OA n=149) completed an Internet-based survey. Coping style was assessed using the validated short version of the Miller Behavioral Style Scale. Measures related to aspects of medication information receipt and discussion and validated measures of ambiguity aversion and medication adherence (Vasculitis Self-Management Survey) were collected. Pearson correlation coefficients, ANOVA, independent samples t-tests and multiple regression models were used to assess associations between coping style and the other variables of interest.

Results:
Arthritis patients in our sample were more likely to be high monitors (50%) than high blunters (36%). Among RA patients, increased information-receipt was significantly associated with decreased monitoring (b = -1.06, p = .001). Among OA patients, increased information-receipt was significantly associated with increased blunting (b = .60, p = .02).

Conclusion:
In our sample of patients with arthritis, attentional coping style is not in accordance with the characteristic patterns outlined in the acute and chronic disease coping literature.
A Model of Aggregate Reporting Quality
Authors: Nagar Venky , Petacchi Paolo 
Published: October 2016

ABSTRACT
We characterize firms' aggregate reporting quality in an economy where a rational capital market, as well as a regulator, discipline firms' reporting choices. When the regulator is resource-constrained, multiple aggregate reporting choices are possible in equilibrium. This multiplicity is driven not just by the regulatory constraint, but also by how this constraint interacts with managerial incentives and the level of reporting discretion available to firms. The model offers concrete explanations for empirical findings linking aggregate reporting quality to underlying institutions, and suggests new empirical approaches that can exploit multiplicity to create more powerful tests.

ABSTRACTObjective: To evaluate the effect of occlusal plane control on the hyoid bone position and pharyngeal airway of hyperdivergent skeletal Class II patients during orthodontic treatment.Materials and Methods: Cephalograms of 47 hyperdivergent skeletal Class II subjects with occlusal plane control (OPC), and another 50 subjects without occlusal plane control (NOPC) were selected to compare the effects of the occlusal plane control procedure. Lateral cephalograms before treatment (T1), immediately after treatment (T2), and an average of 12 months after treatment (T3) were obtained, and 17 measurements were analyzed in each group and compared between groups.Results: With respect to the T2−T1 changes, the sagittal discrepancies in both groups were alleviated. In the OPC group, both the occlusal and mandibular plane angles decreased, accompanied by anterior and superior movement and counterclockwise rotation of the hyoid bone. The overall changes from T3 to T1 in each group exhibited trends similar to that induced by treatment. As for pharyngeal airway space alterations, no significant difference in OPC group was presented throughout treatment or retention periods.Conclusions: The customized occlusal plane control procedure was effective for hyperdivergent skeletal Class II patients: The occlusal plane rotated counterclockwise, followed by a counterclockwise rotation of the mandibular plane. The hyoid bone moved anteriorly and superiorly, accompanied by its counterclockwise rotation. However, this procedure did not induce significant alteration of the pharyngeal airway space.

OBJECTIVEExtent of resection is an important prognostic factor in patients undergoing surgery for glioblastoma (GBM). Recent evidence suggests that intravenously administered fluorescein sodium associates with tumor tissue, facilitating safe maximal resection of GBM. In this study, the authors evaluate the safety and utility of intraoperative fluorescein guidance for the prediction of histopathological alteration both in the contrast-enhancing (CE) regions, where this relationship has been established, and into the non-CE (NCE), diffusely infiltrated margins.METHODSThirty-two patients received fluorescein sodium (3 mg/kg) intravenously prior to resection. Fluorescence was intraoperatively visualized using a Zeiss Pentero surgical microscope equipped with a YELLOW 560 filter. Stereotactically localized biopsy specimens were acquired from CE and NCE regions based on preoperative MRI in conjunction with neuronavigation. The fluorescence intensity of these specimens was subjectively classified in real time with subsequent quantitative image analysis, histopathological evaluation of localized biopsy specimens, and radiological volumetric assessment of the extent of resection.RESULTSBright fluorescence was observed in all GBMs and localized to the CE regions and portions of the NCE margins of the tumors, thus serving as a visual guide during resection. Gross-total resection (GTR) was achieved in 84% of the patients with an average resected volume of 95%, and this rate was higher among patients for whom GTR was the surgical goal (GTR achieved in 93.1% of patients, average resected volume of 99.7%). Intraoperative fluorescein staining correlated with histopathological alteration in both CE and NCE regions, with positive predictive values by subjective fluorescence evaluation greater than 96% in NCE regions.CONCLUSIONSIntraoperative administration of fluorescein provides an easily visualized marker for glioma pathology in both CE and NCE regions of GBM. These findings support the use of fluorescein as a microsurgical adjunct for guiding GBM resection to facilitate safe maximal removal.
