Comparison of stress transmission between implant-supported overdenture and removable partial denture prostheses in the edentulous mandible
Authors: Ozel Gulsum Sayin , Inan Ozgur , Ozyilmaz Ozgun Yusuf 
Published: August 2019

Abstract
Background: A new treatment concept using two or four implant-supported fixed prosthesis-retained removable partial dentures has been proposed for an edentulous mandible. However, the stress transmission of this new system is unknown. The purpose of this study was to compare the stress transfer characteristics of two different types of implant-supported prostheses (implant-supported overdentures and implant-supported removable partial dentures) retained by two or four implants via photoelastic stress analysis.
Methods: This study was designed to evaluate the force transmission of commercially available titanium implants inserted into edentulous mandibles composed of photoelastic resin within two to four implants using two different types of prosthesis: overdentures and implant-retained removable partial dentures. In all models, implants were placed parallel to each other and the midline. A 300 N load was applied first to the premolars. Loading and stress distributions were photographed after the completion of the prostheses.
Results: In the models with two implant-retained removable partial dentures, the stress distribution was found to be lower than that with the four implant-retained removable partial dentures. The locator, a stud attachment, showed the most equitable stress distribution for overdenture models. Despite this, non-splinted implants caused high stresses around the distal implant on the loading side.
Conclusions: When models were compared, the stress loads were transmitted to other implants by splinting. Acceptable stresses were observed in implant-supported removable dentures, especially those with precision attachments. Implant-supported removable partial dentures with an anterior fixed prosthetic design may serve as an acceptable and affordable alternative treatment option. These dentures appear to be advantageous in terms of stress transmission considering effects such as ease of use, esthetic requirements, patient requests, and reduction in the area covered by the prosthesis.
ANTIFUNGAL SUSCEPTIBILITY OF BIOFILM PRODUCING Candida albicans ISOLATED FROM ORAL CAVITY OF DIABETIC AND NON-DIABETIC POPULATION OF DHARAN, NEPAL
Authors: Shrestha Bijay kumar , Shakya Jenish , Khanal Hemanta 
Published: August 2019

Abstract
Background: Candida are almost universal on normal adult skin and C. albicans is part of the normal flora of the mucous membranes of the respiratory, gastrointestinal, and female genital tracts. It is acknowledged that diabetic patients are more susceptible to infections caused by Candida albicans due to increased blood glucose and inability of immune system in eradicating the fungus. Studies suggest that Gutkha consumers are also at high risk of oral Candida carriage .
Materials and methodology

The participants were provided 10 ml of Normal saline and were asked to oral rinse for 1 minute. Oral rinse was collected in a sterile screw capped container and was transported in cold chain to microbiology laboratory. The oral rinse sample was inoculated onto the Sabouraud dextrose agar with Chloramphenicol and was incubated at 37°C for 3-4 days. The Colony forming Unit of candida was compared among diabetic and healthy controls. The candida albicans were identified by Germ tube formation. The Candida albicans isolates were subjected to Biofilm assay, Antifungal susceptibility Test, Haemolysin assay, Haemolysis degree and phospholipase assay.

Result: This study reported 31.5% prevalence of oral Candida.The Candida carriage in CFU of diabetic population was statistically significant (p<0.05). The maximum isolates were found to be Biofilm producers. There was significant association between Gutkha consumers with oral Candida carriage. The study suggests that there is higher colonization of Candida in diabetic populations than in healthy population. The result also concludes that frequency of Candida in Oral cavity of Gutkha consumers was also higher (p<0.05). All isolated strains of Candida albicans were tested for antifungal susceptibility testing and 76.19% were found to be Resistant to Fluconazole and 50% were found to be resistant to Amphotericin B. There was statistical significance in Biofilm formation and fluconazole Drug resistance.

Conclusion

The findings indicated highest colonization of oral Candida in diabetic population and in Gutkha consumers. The greatest numbers of isolated Candida albicans were biofilm producer which showed greater frequency of Fluconazole drug resistance.

Abstract
Purpose: To comprehensively analyze the scientific outputs of cancer topic of Cochrane systematic reviews (Cancer-CSR).
Patients and methods: Cochrane Database of Systematic Review and Web of Science Core Collection were retrieved limited from Jan. 1, 2009 to Dec. 12, 2018. CiteSpace IV and Excel 2018 were applied to analyze and visualize the literature information.
Results: Ultimately, 607 Cancer-CSR were retrieved, 32 countries, 179 institutions and 260 authors involved. The number of publications in Cancer-CSR has been increasing over the past decades (25(2009)-77(2018)). UK, USA, Canada, Australia, and Germany worked closely with other countries, especially UK (n=361) has taken the lead in this field. The top 10 contributive institutions, which were almost came from developed countries, collaborated closely with other institutions. Cochrane Database Syst Rev, C Hdb Sys and J Clin Oncol were the top three journal/book with the highest co-citation. The top three co-cited references were the two different version of Cochrane handbook for systematic reviews and the guidelines of Review Manager. The biggest cluster of keywords “cytoreductive surgery (CRS)” and the latest clusters “visual inspection” and “non-steroidal anti-inflammatory drug” were the most promising hotspots.
Conclusions: Cancer-CSR has been increasing. Most of the reviews were came from the developed countries as well as the institutes in these countries. The knowledge base of were the methodology studies of systematic review, epidemiological data of cancer, and the reporting guideline of systematic reviews. The adjuvant therapy combined CRS, the screening of skin cancer and the management of cancer-related pain were the hotspots.

Published: August 2019

Abstract
Background:
Infection is a leading cause of morbidity and death in patients with multiple myeloma (MM). The increased susceptibility to infection is complicated and multifactorial. However, none of the studies had assessed the risk of infection in MM patients who didn’t receive the antitumor treatment. For the first time, this study aimed to provide ideas for the assessment, prevention and treatment of infection in newly diagnosed MM patients without antitumor therapy.
Methods:
Retrospectively, the data from electronic medical records for 161 cases of hospitalized patients with multiple myeloma were analyzed, during May 2013 to December 2018. Independent risk factors of infection in multiple myeloma were determined by univariate and multivariate analysis.
Results:
Newly diagnosed patients with MM were highly susceptible to viruses (43.9%), especially the EBV (24.4%) and HBV (17.1%). More advanced stage (ISS-Ⅲ stag, P=0.040), more severe anemia (Hb<90 g/L, P=0.044) and the elevation of CRP (>10 mg/L, P=0.006) were the independent risk factors of infection. Moreover, infections represented a major threat to patients with newly diagnosed MM (P = 0.033), and the existence of risk factors for infection was significantly related to poor prognosis (P = 0.011), especially the ISS-Ⅲ stage (P=0.008) and lower hemoglobin level (P=0.039).
Conclusions:
MM patients without antitumor therapy are highly susceptible to viruses. Advanced ISS stage, more severe anemia and the elevation of CRP were identified as independent risk factors of infection, which also have a strong impact on the prognosis. Our results suggest that the viral infection should be taken into account if antibacterial drugs are not effective, and the prevention of infection and improvement of prognosis should be paid more attention to in the newly diagnosed patents with more advanced stage and more severe anemia.
Influence of design parameters on the treatment performance of VF wetlands – a simulation study
Authors: Pucher Bernhard , Langergraber Guenter 
Published: August 2019

Abstract
The main approach for designing vertical flow (VF) treatment wetlands is based on areal requirements ranging from 2 to 4 m2 per person equivalent (PE). Other design parameters are the granularity of the filter material, filter depth, hydraulic and organic loading rates, loading intervals, amount of single doses as well as the number of openings in the distribution pipes. The influence of these parameters is investigated by running simulations using the HYDRUS Wetland Module for three VF wetlands with different granularity of the filter material (0.06–4 mm, 1–4 mm, and 4–8 mm, respectively). For each VF wetland, simulations are carried out at different temperatures for different organic loading rates, loading intervals and number of distribution points. Using coarser filter material results in reduced removal of pollutants and higher effluent concentrations if VF wetlands are operated under the same conditions. However, the treatment efficiency can be increased by applying more loadings and/or a higher density of the distribution network. For finer filter material, longer loading intervals are suggested to guarantee sufficient aeration of the VF filter between successive loadings.

Published: August 2019

BackgroundStroke is one of the top 10 leading diseases worldwide, with high mortality and morbidity rates. There is an incomplete understanding of the various types of self-efficacy involved in the prevention of recurrent stroke, and one of them is medication-taking self-efficacy.ObjectiveThis study aimed to explore the fundamental needs and barriers of medication-taking self-efficacy in poststroke patients in Malaysia.MethodsWe performed in-depth individual interviews with poststroke patients (N=10) from the Outpatient Neurology Clinic, Hospital Kuala Lumpur. All interviews were transcribed verbatim, and an inductive thematic analysis was performed on the data collected from the interviews.ResultsTwo key themes were identified: (1) self-efficacy in taking the effort to understand stroke and its preventative treatment for recurrent stroke and (2) self-efficacy in taking prescribed medication to prevent stroke. Patients needed to be proactive in seeking reliable information about stroke and the perceived benefits of preventative treatment for stroke. The discussion was focused on eliciting the needs and barriers related to medication-taking self-efficacy. Patients needed to develop independence and self-reliance to overcome barriers such as dependency and low motivation. External factors such as limited information resources, low perceived severity, poor social environment, and poor communication add to the challenges of poststroke patients to improve their self-efficacy of managing their medications.ConclusionsThe study identified potential key findings related to the needs of patients in a localized setting, which are also related to several health behavioral concepts and constructs, indicating the importance of overcoming barriers to improve the quality of life in poststroke patients. We anticipate that the results will be taken into consideration for future personalized patient education interventions.

Los calendarios de Xochicalco, Morelos
Authors: Morante López Rubén Bernardo 
Published: August 2019

<p>Los calendarios de Xochicalco pueden ser conocidos gracias a las numerosas fechas que quedaron inscritas en los relieves de la zona. El registro y análisis de sus signos nos ha servido para completar la secuencia de sus días y los años que componen las trecenas que integran el periodo de 52 años, el llamado “siglo mesoamericano”. El que los signos procedan de un solo sitio y correspondan a un mismo periodo, los convierte en una fuente única para conocer el calendario prehispánico durante el Epiclásico, (600 a 900 d.C.); y esta temporalidad hace que sean un eslabón entre los calendarios que se usaron en el centro de México desde el Clásico hasta el Posclásico. En Xochicalco se presentan estilos artísticos y representaciones gráficas de palabras e ideas con cierto eclecticismo, reflejo de las influencias y contactos tras-regionales que caracterizaron a la Mesoamérica de entonces. El calendario no es excepción, nos ayuda a llenar partes medulares del complejo rompecabezas que constituye la calendárica prehispánica, misma que, partiendo de Teotihuacán, llegó a las culturas mexica y mixteca, mejor conocidas gracias a los códices y escritos de los cronistas del siglo XVI. </p>
Memories of Faraway Visitors to Southeast Asia: the ‘Portuguese fort’ in Amurang
Authors: Schouten Maria Johanna 
Published: August 2019

ABSTRACT: This article examines today’s perception among Indonesians of the Portuguese presence in Eastern Indonesia during the sixteenth and seventeenth centuries. Despite evidence of the often violent pursuit of supremacy and material benefit by European navigators, the local population has different understandings of the past. An assessment of these from an anthropological perspective is guided by twin concepts such as emics and etics, and memory and history. Our case study combines documentary research and fieldwork, focusing on a colonial fort in the town of Amurang, on the island of Sulawesi. The present-day accounts of the local population and of some official organizations attribute a Portuguese origin to this fort, and narratives about the Portuguese abound in folk memory, often contradicting the findings of scientific research. Most significant is the positive image of the Portuguese prevalent among the population. The article includes historical data on the Portuguese and Spanish presence in Indonesia and ethnographic data of Amurang, as well as architectural and archaeological details of the fort.Keywords: Forts Folk memories Postcolonialism Portuguese Indonesia Memórias de visitantes longínquos ao Sudeste Asiático: a ‘fortaleza portuguesa’ em AmurangRESUMO: Este artigo examina a perceção existente na atualidade entre os indonésios relativamente à presença portuguesa no arquipélago entre os séculos XVI e XVII. Apesar de as evidências demonstrarem que a busca por supremacia e benefícios materiais por parte de navegadores europeus foi realizada com recurso à violência, a população local apresenta versões diferentes deste passado. Numa análise destas versões, seguindo uma abordagem antropológica, é útil a aplicação de binómios como emics e etics, e memória e história. Para o presente estudo foi efetuada investigação de terreno e documental sobre um forte colonial da cidade de Amurang, na ilha de Sulawesi. Nas numerosas narrativas populares e no discurso oficial sobre os portugueses, estes foram os construtores deste forte, contradizendo conclusões de investigação científica. Sobressai a prevalência junto da população de uma imagem positiva dos portugueses. O artigo inclui informação histórica relativa à presença portuguesa e espanhola na Indonésia, dados etnográficos de Amurang, assim como detalhes arquitetónicos e arqueológicos do forte.Palavras-chave: Fortalezas; Memórias populares; Pós-colonialismo; Portugueses; Indonésia
Implicit Corporate Taxes and Income Shifting
Authors: Markle Kevin S. , Mills Lillian F. , Williams Braden 
Published: August 2019

ABSTRACT
The effects of tax rate changes on corporate profitability are not fully understood. Implicit tax theory predicts a positive relation between country-level tax rates and firm-level pretax returns. Conversely, income shifting should make reported pretax returns inversely related to tax rates. Among single-country European firms, we find robust evidence of corporate implicit taxes following tax rate changes, concentrated in firms that rely less on intangible assets and firms in closed economies (non-EU countries). Among multinational firm affiliates, we find the effects of income shifting outweigh the effects of implicit taxes for firms with high intangibles and in countries with open borders. Our results imply income shifting estimated using only reported profits is less biased by implicit taxes in settings with open economies and firms with unique inputs or products. Our evidence also helps explain prior evidence of decreasing corporate implicit tax effects over time, particularly for multinationals.

Authors: Wang Yunsen , Kogan Alexander 
Published: August 2019

ABSTRACT
This study introduces the database architecture that manages data in the main physical memory using columnar format. It proposes a conceptual framework for applying the in-memory columnar database systems to support high-speed continuous audit analytics. To evaluate the proposed framework, this study develops a prototype and conducts simulation tests. The test results show high computational efficiency and effectiveness of the in-memory columnar database relative to the conventional ERP system. Furthermore, the deployment of the in-memory columnar database to the cloud shows the promise of scaling up the in-memory columnar database for continuous audit analytics.
Dynamic Viscoelastic Characterization of Bulk-fill Resin-based Composites and Their Conventional Counterparts
Authors: Yap AU , Eweis AH , Yahya NA 
Published: August 2019

SUMMARYThis study compared the viscoelastic properties of restorative and flowable bulk-fill resin-based composites (RBCs) with their conventional counterparts and evaluated the impact of aqueous solutions on viscoelastic properties. The materials examined included three conventional RBCs (Filtek Z350, Tetric N Ceram, and Beautifil II), three restorative bulk-fill RBCs (Filtek Bulk-Fill Restorative, Tetric N Ceram Bulk-Fill, and Beautifil Bulk-Fill Restorative) in addition to three flowable bulk-fill RBCs (Filtek Bulk-Fill Flowable, Tetric N Flow Bulk-Fill, and Beautifil Bulk-Fill Flowable). Beam-shaped specimens (12×2×2 mm) were fabricated using customized stainless-steel molds, finished, and measured. The specimens were randomly divided into four groups and conditioned in air (control), artificial saliva, 0.02 N citric acid, and 50% ethanol-water solution for seven days at 37°C. They were then subjected to dynamic mechanical analysis (n = 10) in flexure mode at 37°C with a frequency of 0.1 to 10 Hz. Storage modulus, loss modulus, and loss tangent data were subjected to statistical analysis using one-way analysis of variance/Tukey post hoc test at a significance level of α = 0.05. Viscoelastic properties of the RBCs were found to be product and conditioning medium dependent. For most RBCs, exposure to aqueous solutions, particularly an ethanol-water solution, degraded viscoelastic properties. With the exception of Filtek Bulk-Fill Restorative, bulk-fill restorative and flowable RBCs generally had significantly lower storage and loss modulus than their conventional counterparts regardless of conditioning medium. Conventional RBCs are thus favored over their bulk-fill counterparts, particularly for high-stress-bearing areas.
The Organizational Culture of Selected Private Higher Education Institutions in Bulacan as Correlates to Work Values of Their Faculty Members: Bases for an Enhancement Program
Authors: B. TOLENTINO DR. AILEEN 
Published: August 2019

This study attempts to establish a significant relationship between the prevailing organizational culture and the dominant work values of faculty members in three higher education institutions in Bulacan, Philippines—Centro Escolar University, La Consolacion University Philippines, and Baliuag University—in the first semester of academic year 2015-2016 with the view of crafting an enhancement program on organizational culture. Respondents answered questions on the organizational culture and their dominant work values and how these two factors interact. Findings show a strong organizational culture pervading the three institutions and the faculty putting a high premium on achievement, continuous learning in the work place, leadership of their superiors and being able to help others in the performance of their duties and responsibilities. The study recommends motivating the faculty to pursue post-graduate degrees in their area of specialization and for the institutions to conduct seminar-workshops on professed work values and prevailing organizational culture towards creating a work culture that fosters achievement, continuous learning, and supportive relationships among administrators, faculty and non-teaching personnel.
