Authors: Pegito Irene , Lambeck Johan , Torres-Parada Manuel , Vivas Miranda José García , Costa Jamile Vivas
Published: August 2018

INTRODUCTION: A high percentage of post-stroke patients have permanent aftermathsdespite conventional rehabilitation. Circuit class training offers an efficient way to achieve structured practice of task-related activities during stroke rehabilitation. Aquatic therapy is another therapeutic approach that offers a great variety of options to be a highly dynamic environment, which helps to improving functionality and recover quality of life and independence in people with disabilities. OBJECTIVE: To develop a protocol for a randomized controlled trial. METHODS: Forty participants will be randomized in two groups: aquatic circuit class training (ACCT) and land circuit class training (LCCT). In both groups, the intervention will be a 7-week class therapy, 3-times weekly, giving a total of 20 sessions, 60 minutes each. Blinded assessors will conduct assessments, using standardized tools: baseline, post-intervention, and 20 days follow-up for the effectiveness of the therapy in terms of gait, balance and upper limb motor function. RESULTS/CONCLUSION: This trial will examine the immediate and medium term effect of an ACCT program as compared to a LCCT program in people with stroke. It has the potential to identify interventions that may improve rehabilitation of these patients. Both CCT programs are based in International Classification of Function, Disability and Health model with activities aimed at impairment, activity and participation levels.

Published: August 2018

Em um cenário de crescimento do uso de substâncias psicoativas entre universitários, a presente pesquisa objetivou levantar o uso destas substâncias conforme o sexo (homem e mulher), a situação de trabalho (estar trabalhando ou não) e a idade (jovem com menos de 29 anos e os demais) no contexto de duas instituições de ensino superior do setor privado com fins lucrativos em Belo Horizonte. Do ponto de vista metodológico, aplicamos questionários estruturados em 868 estudantes em sessões coletivas em sala de aula. Todos os participantes responderam anonimamente. Desenvolvemos análises estatísticas das respostas. A análise fatorial identificou dois tipos de sustâncias psicoativas – Prescritas e Não Prescritas. As análises de regressão mostraram que apenas o sexo apresenta capacidade preditiva dos escores nos fatores. O uso de café como substância estimulante é mais frequente entre os estudantes trabalhadores e com mais de 29 anos. Os resultados podem ser importantes para a construção de instrumento específico, bem como para orientar novos levantamentos acerca da dinâmica do trabalho influenciando tais condutas.

О пределах применимости демографических прогнозов ООН
Authors: Сороко Евгений Львович
Published: August 2018

В 2017 г. был опубликован очередной прогноз мирового населения, сделанный Отделом народонаселения ООН. Согласно этому прогнозу, к 2050 г. численность населения мира составит 9,772 млрд человек, к 2100 г. – 11,184 млрд. В целом этот прогноз не противоречит ни предыдущими прогнозам ООН, ни прогнозам, выполненным другими организациями. Тем не менее он иногда вызывает и достаточно резкие критические замечания. В данной статье предпринята попытка разобраться в том, что могло послужить причиной критики: новая методика прогнозирования и ее существенная доработка или полученные результаты. С этой целью проведен анализ последних прогнозов ООН, методик их составления, использованных данных, результатов прогнозирования, выполненного за последние 15 лет. Обсуждаются недостатки прогнозов ООН, а также ограничения и условность их возможного применения. Показано, что среди возможных причин повышения в последних прогнозах оценок перспективной численности населения мира к наиболее важным могут быть отнесены: 1) завышение прогнозной младенческой и детской смертности в предыдущих прогнозах; 2) преуменьшение темпов снижения рождаемости в некоторых африканских странах. Предложено обоснование того, что краткосрочные демографические прогнозы должны вызывать доверие и могут быть использованы в практических целях, и отмечена условность применения долгосрочных прогнозов, так как возможные многочисленные непредсказуемые факторы будущего сильно снижают их точность. На уровне отдельных стран большую неопределенность долгосрочного прогноза могут обусловливать крутые повороты в демографической политике или социально-политическом устройстве, что иллюстрируется примерами некоторых стран.

Défis et évolution de l'accompagnement offert aux professeurs de langue par le Régime d'immersion en français (RIF) de l'Université d'Ottawa
Authors: Thibault Laurence Valérie , Gobeil Marc
Published: August 2018

Depuis 2006, le RIF offre des cours d’encadrement linguistique (CEL) associés à des cours de discipline enseignés dans cinq facultés de l’université (soit 86 programmes en 2016-2017). Cependant, les professeurs de FLS sont très rarement formés à l’enseignement  propre à ce type de cours qui sont développés sur mesure en lien avec chaque cours de discipline. Pour répondre à ce défi, le RIF offre, par l’entremise des responsables pédagogiques, un accompagnement dont la nature et le format ont évolué au fil des ans.D’abord, les professeurs ont reçu une formation initiale (création de ressources, réunions, ateliers, observations de classes suivies de recommandation) (Weinberg, A., et S. Burger, 2006). Puis, les responsables pédagogiques ont créé deux recueils rassemblant des activités conçues par les professeurs désormais expérimentés (Dansereau et Buchanan, 2009, 2011; Dansereau, 2011). Ces recueils sont devenus des incontournables pour les nouvelles recrues et ont contribué au développement d'une communauté de pratique. Aujourd'hui, l'accompagnement se caractérise par des consultations, des rencontres de partage de pratique et la vérification du respect des objectifs pédagogiques dans les plans de cours.Dans quelle mesure l’accompagnement reçu jusqu’à présent répond-il aux besoins des professeurs? Quels sont leurs nouveaux besoins ? Dans quelle direction et sous quelle forme l’accompagnement peut-il évoluer de façon à maximiser et reconnaître les savoir-faire développés par cette communauté de pratique afin qu’elle profite au plus grand nombre? Grâce aux résultats d’un sondage envoyé en janvier 2017 à tous les professeurs ayant enseigné un CEL depuis 2006 nous pouvons identifier les forces et les faiblesses de l’accompagnement déjà offert et envisager la mise en place de nouvelles stratégies d’accompagnement.

Lessons learned from immersion in western Canada’s multilingual and multicultural post-secondary context across the disciplines
Authors: Spiliotopoulos Valia
Published: August 2018

The current educational context in post-secondary institutions world-wide is characterized by a widening participation agenda, and is greatly impacted by trends in globalization and internationalization (Burbules & Torres, 2000, Ilieva, Beck, & Waterstone, 2014).  This multilingual and multicultural educational context brings about many opportunities and challenges for students, faculty, and other internal and external stakeholders (Arkoudis et al, 2012; Hafernick & Wiant, 2012; Murray, 2016). Given Canada’s increasing involvement in offering programs predominantly in English to international, transnational, and bi/plurlilingal domestic students, it is important to examine the lessons learned from Canada’s history with immersion (Cummins, 1998).   and consider the implications for the post-secondary context (Knoerr, et al. 2016). To that end, it is perhaps time to reconsider language education policies, re-examine how language is used as a medium of instruction, redesign curriculum and instruction, as well as understand how students’ bi/plurlingualism can serve as an additional resource for learning across the disciplines (Camarata, 2016; Coste, Moore & Zarate, 2009;  Cummins, 2007; Marshall and Moore, 2013).

 

This article describes the educational development and scholarly activities of a Centre for English Language Learning Teaching, and Research at a comprehensive university in British Columbia, and shares emergent findings of a case study and pilot projects in which faculty in applied linguistics/language education collaborate with faculty across the disciplines to support students’ English language development alongside their disciplinary knowledge and literacy skills at the curricular, instructional, and assessment levels. Key practices and approaches in university French immersion education will be compared and contrasted with Content-based/‘CLIL’ and plurilingual approaches used by language education faculty working alongside disciplinary faculty in order to support students at the curricular core within programs where English is the language of instruction.
The role of obesity in male fertility
Authors: Mermer Meltem , Akdevelioğlu Yasemin
Published: August 2018

Obesity causes many health problems as well as having negative effects on fertility. There is a multifaceted relationship between obesity and male infertility. Male fertility is associated with sperm concentration, motility and morphology. Testosterone (total and free) and gonadotropin levels were low and estrogen levels were found to be high in obese men. The decrease in androgen levels varies based on the degree of obesity. High body mass index is inversely related to total sperm count, sperm concentration, sperm morphology and number of motile sperm. Leptin and ghrelin are hormones that influence body weight regulation and eating behaviors. Serum leptin level, which is high in obese infertile men, showed a significant positive correlation with abnormal sperm morphology, serum FSH, LH, prolactin level and showed a significant negative correlation with sperm concentration, sperm motility and serum testosterone level. Further research is needed on the effects of ghrelin levels on male infertility. The relationship between obesity and erectile dysfunction can be explained by decreased testosterone levels and elevation of some proinflammatory cytokine levels. Decreased physical activity due to obesity, long-term sitting increases testicular temperature and affects sperm production negatively. There is a multifaceted relationship between obesity, metabolic syndrome and type 2 diabetes and serum testosterone and SHBG. Diet and exercise showed improvement in testosterone levels and sperm concentration due to decreased body weight. However, studies on this subject are extremely limited. The possible effects of weight loss on successful infertility treatment of obese men should not be ignored.
Incidental gynaecological malignancy in women who underwent hysterectomy for utero-vaginal prolapse: a 3-year institutional case study
Authors: Seles Fathima M. , Indira Rajavelu
Published: August 2018

Background: Pelvic organ prolapse is common is almost 50% of women over the age of 50years. The objective of the present study was to estimate the number of incidental gynaecological malignancies in women who underwent hysterectomy for utero-vaginal prolapse.Methods: 354 women who presented with asymptomatic utero-vaginal prolapse were included in this study. Women who were symptomatic with bleeding per vaginum, lower abdominal pain or excessive white discharge and preoperative screening tests such as VIA/VILI, colposcopy, Pap smear and radio-imaging showing any gynaecological lesions were excluded from this study.Results: Histopathological examination of the hysterectomy specimen showed premalignant lesion in 13 cases accounting to 3.7% (11 cases of CIN I, 1 case of CIN II, 1 case of CIN III) and malignant lesions in 5cases accounting for 1.4% (4 cases of endometrial adenocarcinoma and 1 case of cervical squamous cell carcinoma).Conclusions: Asymptomatic women with utero-vaginal prolapse may have pre-existing premalignant and malignant lesions. Therefore, all women undergoing hysterectomy should be preoperatively screened with transvaginal ultrasound, endometrial biopsy and pap smear to rule out malignancy, as the management differs for patients with co-existing gynecological malignancies.

Authors: Bhadarka Nagajan , Poddar Krutika , Joshi Satyam
Published: August 2018

Background: The aim of the present study was to evaluate the ability of the random urine P/C ratio to predict significant proteinuria, as well as to introduce a diagnostic test for preeclampsia that would avoid the inconvenience and time consumption of 24-hour urine protein collection.Methods: A total of 100 women who were pregnant were included in the study. For urine test, the urine was collected for 24 hours. The women patients provided the mid stream urine sample prior to the collection period. Biuret colorimetric assay was used to determine the total protein in the urine and the creatinine concentration was measured with the help of modified Jaff test.Results: The mean urinary protein excretion in 24 hour urine collection was found to be 2.05±0.74 g/dl and the median serum creatinine concentration was found to be 0.82 mg/dl.  The mean p/c ratio was found to be 1.94±0.83. The correlation coefficient for the p/c ratio against the 24 hour urine protein excretion was found to be 0.88.Conclusions: This test can also be used as a reasonable alternative to 24-hour urine protein excretion, especially in emergency situations, and, it could also complement the urinary dipstick test in preeclamptic pregnancy.

Published: August 2018

Background: Semen analysis forms the basic investigation for male factor of infertility. According to WHO Manual sperm values of normalcy are decreasing. Recent studies have highlighted newer parameters of sperm playing their role in the outcome of pregnancy. The aim was to study the DNA fragmentation index (DFI) and to know its correlation with other sperm parameters.Methods: A total of 4833 cases underwent routine semen analysis along with the DFI. The statistical analysis was done using SPSS using t test and ANOVA test.Results: It was observed that 52% infertile males presented late for treatment. All parameters showed a decline with advancing age. There was definite correlation between sperm count and sperm motility as well as morphology. The DFI showed significant negative correlation with sperm count. Pearson correlation showed positive correlation between DFI and sperm motility and morphology.Conclusions: The study highlights the need for increasing awareness about male factor of infertility. A thorough semen analysis along with DFI can help the clinician to explain the couple in a better way about the choice of ART and success of treatment.
A cross-sectional study of fertile period awareness, knowledge, attitudes and practice in infertile couples seeking fertility assistance
Authors: Kshrisagar Shilpa Pankaj , Shirsath Arti Sidharth
Published: August 2018

Background: Infertility is one of the most distressful condition for a couple. Medical interventions may exacerbate anxiety, depression, stress, loss of self-esteem, guilt and grief in these couples. But many studies indicate that most cases of infertility can be attributed to a physiological cause in the man or woman. Previous research has suggested that poor fertility period awareness may be a contributing cause of infertility among couples seeking assistance at infertility clinics. The actual practices and attitudes towards fertility-awareness in this particular group of patients are unknown and need to be explored. The aim of the present study was to report the study of fertile period awareness and their knowledge, attitude and practice in the infertile couples seeking fertility assistanceMethods: This is a cross-sectional questionnaire-based study. The study was conducted over a period of 6 months from June to December 2017 in the couples attending the infertility clinic at Smt Kashibai Navale Medical College and General Hospital, Pune.Results: Total 246 of 280 distributed questionnaires were completed (response rate =87.8%). Out of these 60% (n=147) believed they had timed intercourse within the fertile window of the menstrual cycle in their attempts at conception, but surprisingly only 36%(n=52) could accurately identify this window. In this study 23% (n=56) participants had already taken prior treatment but still 50% were ignorant about fertile window. It was shocking that among 246 only 15% (n=38) couples were actually practising fertile period due to some reasons and most of them did not know or rely upon the concept of fertile period. Almost 94% of them believed that they should receive fertility-awareness education when they ﬁrst report trouble in conceiving to their doctor.Conclusions: Most couples seeking assistance at infertility clinics were unaware of the fertile window of the menstrual cycle and only few could accurately identify this window, suggesting that poor fertility awareness may be a contributing cause of infertility.
Comparative study of perinatal outcome between abdominal and vaginal route of delivery in case of breech presentation
Authors: Tripathy Gourav Ranjan , Smitha M. , Acharya Anand
Published: August 2018

Background: Breech presentation is also one of the most interesting subjects in obstetrics as no other malpresentation has so many manoeuvres during vaginal delivery and their impact on perinatal mortality. The mode of delivery also depends on so many variables like parity, type of breech presentation, associated obstetric complications, estimated birth weight etc and also from obstetrician point of view.Methods: Pregnant mother with breech presentation of gestational age 32 weeks or more were included in this study. Multiple pregnancy with first baby in breech presentation were excluded from this study. New born baby with gross congenital anomalies like anencephaly, omphalocele were excluded from this study. The cases for present study were collected from antenatal OPD, labour room, High-risk ward and Post-natal ward of KIMS & RF from June 2016 to December 2017.Results: Out of 61 cases of caesarean section there were 4 cases (6.55%) of neonatal death. PNM among the 100 cases was 4% in caesarean section. In 32 assisted breech delivery cases there were 8 cases (25%) of perinatal death. PNM among the 100 cases was 8% in assisted breech delivery. Out of 4 cases of breech extractions there were 3 cases (75%) of perinatal death. PNM among the 100 cases was 3% in breech extraction.Conclusions: Present study suggests that breech delivery should preferably be always managed in the hospital by skilled and experienced obstetrician with an assistant in collaboration with a pediatrician and an anesthetist. As good numbers of babies were premature a good premature care unit should be pre-managed under the supervision of a pediatrician.

Published: August 2018

Background: Polycystic Ovarian Syndrome (PCOS) is a multifactorial, polygenic and multisystem endocrine disorder affecting women in reproductive age. PCOS diagnosis is based on 2003 Rotterdam criteria It has been noted that hyperinsulinemia is a central factor in the pathogenesis of PCOS. Many studies show evidence of a critical link between PCOS and Metabolic Syndrome (MBS).Methods: It was a hospital - based observational study done over a period of one year with a sample size of 177.An observational study was done in patients satisfying the inclusion and exclusion criteria. After taking informed and written consent, history was obtained from the patient to know the age, socioeconomic status, present and past clinical history, menstrual and obstetric history, personal and family history and any other history as deemed necessary. Patient was clinically assessed to know the height, weight, body mass index.Results: The prevalence of MBS was 37.2%. The commonest age group was between 25- 35 years.There is no statistical association between educational qualification, economic status and the prevalence of MBS and There no significant association between the presence of acne, androgenic aloepecia and the presence of PCOS.While the presence of increased waist circumference > 88cms, USG findings consistent with PCOS, high blood pressure > 130/85 mm of Hg, elevated FBS > 110 mg/dl, low HDL <50 mg/dl were statistically significant.Conclusions: The results can be used to formulate a screening policy for metabolic syndrome, particularly in the low resource settings of developing countries.
Successful term pregnancy after uterine artery embolization for caesarean scar ectopic pregnancy: a case report
Authors: Job Angeline , S. Spandana
Published: August 2018

The incidence of caesarean scar pregnancy range from 1 in 1800 to 1 in 2500 of all pregnancies. It has been estimated that 6.1% of pregnancies in women with at least one previous Caesarean section and a diagnosis of ectopic pregnancy will be Caesarean scar pregnancy (CSP). There is no consensus on the management of CSP. An invasive intervention such as excision of scar ectopic can reduce recurrence but affects patient’s fertility. Conservative management like administration of methotrexate and uterine artery embolization (UAE) is specially important for young women who want to keep their fertility. This is a case report of a 29-year-old woman who presented with persistent heavy bleeding following failed MTP at 12 weeks of gestation. Ultrasonogarphy was suggestive of Caesarean scar pregnancy and MRI of chronic left adnexal ectopic. Laparotomy also was suggestive of Caesarean scar ectopic. She was managed conservatively with UAE followed by Methotrexate. The procedure was performed successfully, and the patient’s fertility was preserved. Follow up consisted of serial bhCG monitoring which gradually returned to normal levels. She conceived four years after UAE and had an uneventful antenatal period and underwent Elective Cesaraen section at 38 weeks. For those patients with CSP who desire future pregnancy, the comprehensive treatment including UAE can be considered in management.

Genetic diversity caused by transposable element movement can play an important role in plant adaptation to local environments. Regarding genes, transposon-induced alleles were mostly related to gene bodies and a few of them to promoter areas. In this study, the promoter regions of 9 stress-related genes were searched for transposable element insertions in 12 natural variants of A. thaliana. The promoter screening was performed via PCR amplification with primers designed to flank transposable element insertions in the promoter areas of the reference accession Col-0. Transposable element -associated insertion/deletion (indel) polymorphisms were identified in 7 of the 12 promoter loci across studied accessions that can be developed further as molecular markers. The transposable element absence in the promoter regions of orthologous genes in A. lyrata indicated that the insertion of these transposable elements in A. thaliana lineage had occurred after its divergence from A. lyrata. Of the genes having indel polymorphic promoters, two genes CML41 (Calmodulin-like protein 41) and CHAP (chaperone protein dnaJ-related) were further analyzed in the accessions Col-0, Ws, Shahdara and Pirin. The observed promoter indel polymorphisms were linked to altered gene expression patterns in the four accessions that were laboratory-grown at 21°C and 36°C. The collected data can be a starting point for gene expression profiling studies under conditions resembling the natural habitats of accessions.

Published: August 2018

The Slovak Pinzgau breed faces the bottleneck effect and the loss of diversity due to unequal use of founders and significant population decline. Further population size reduction can lead to serious problems. High-throughput genotypes of 179 individuals were used to characterise genetic diversity and differentiation of Slovak Pinzgau, Austrian Pinzgau, Cika and Piedmontese cattle by Bayesian clustering algorithm. A gene flow network for the clusters estimated from admixture results was produced. The low estimate of genetic differentiation (FST) in Pinzgau cattle populations indicated that differentiation among these populations is low, particularly owing to a common historical origin and high gene flow. The changes in the log marginal likelihood indicated Austrian Pinzgau as the most similar breed to Slovak Pinzgau. All populations except Piedmontese showed two ways of gene flow among populations indicating that Piedmontese was involved in formation of analysed breeds while these breeds were not involved in creation of Piedmontese. Genetic evaluation represents an important tool in breeding and cattle selection. It is more strategically important than ever to preserve as much of the livestock diversity as possible, to ensure a prompt and proper response to the needs of future generations. The information provided by the fine-scale genetic characterization of this study clearly shows that there is a difference in genetic composition of Slovak and Austrian populations as well as Cika and Piedmontese. Slovak Pinzgau cattle despite its population size has the potential to serve as a basic gene reserve of this breed with the European and World importance.

La población indígena Miskita nicaragüense y el estado costarricense: regularización migratoria y empleo formal
Authors: Villalobos Rojas Millaray
Published: August 2018

El presente documento analiza características socio-demográficas y laborales de la población miskita nicaragüense asentada en San Juan de Pavas en San José, Costa Rica, que tiene alrededor de 30 años de estar inmigrando mayoritariamente desde la Región Autónoma del Atlántico Norte (RAAN). Se abordan las posibilidades actuales de esta población para acceder a la regularización migratoria y al empleo formal, tomando en cuenta que, para beneficiarse de una significativa gama de servicios del Estado costarricense (signatario de múltiples instrumentos internacionales y nacionales para la protección de los derechos humanos de los migrantes, con normativa específica para atender a la población indígena migrante, donde el tema migratorio es oficialmente materia de interés público) y por ende de un proceso efectivo de integración estructural en la sociedad de acogida, se requiere de un Documento de Identidad Migratoria para Extranjeros (DIMEX) vigente. Los datos socio-demográficos que por primera vez colocan a la población miskita en el imaginario de la sociedad costarricense y sus instituciones y que sirven de base para la toma de decisiones, se recopilaron por medio de una encuesta diseñada para ser equiparable con los instrumentos utilizados por el Instituto Nacional de Estadística y Censos (INEC), a través de una coordinación interinstitucional e intersectorial que debe ser visualizada como una buena práctica.

Published: August 2018

Aim: To evaluate the effectiveness of an educational preventive program in oral health on preschoolers. Methods: The final sample was 71 children in the test group and 48 in the control group. Intraoral exams were conducted for caries experience (dmf-s), white spot lesions (WSL) diagnosis, dental biofilm and treatment needs (before and after intervention- the interval was 18 months). Caregivers answered a questionnaire about socioeconomic data and health behavior. The educational preventive program consisted of supervised brushing, education in oral health, fluoride application and lectures to caregivers. Mann Whitney and Wilcoxon tests (p <0.05) were used to compare data between groups. Results: Mean caries experience was 0.94 (± 3.42) and 0.94 (± 2.87) in test and control groups, respectively. Baseline mean for dental biofilm was 4.95, and final mean was 0.21 in test group (p = 0.047). Conversely, the same variables were 4.11 and 0.84 in the control group (p = 0.047). The program was evaluated as very good (54.9% of caregivers), improvement of brushing was related by 62%, and more children went to the dentist (p <0.01). Conclusion: The educational preventive program seems to be effective for dental biofilm reduction, improved brushing and dental visits, being an important strategy for oral health maintenance in children.

Aim: The aim of this study was to verify the microshear bond strength of conventional and self-adhesive resin cements to feldsphatic ceramic. Methods: Twenty discs of Starlight ceramic (Degudent) were made (15mm x 2mm). The bonding procedure was accomplished by insertion of resin cements into tubes of 0.7mm internal diameter in contact with the ceramic. The resin cements used were: RelyX ARC (3M Espe), Panavia F (Kuraray), RelyX Unicem (3M Espe) and seT (SDI). Total of six tubes of each material on each ceramic disc. The specimens were tested for microshear in a universal testing machine, 24hours and 6months after bonding procedure. Values of microshear bonding strength (MPa) were subjected to ANOVA and Fisher PLSD test (p<0.05). Results: For 24hours analysis, RelyX ARC showed the highest microshear bonding strength without statistical difference to RelyX Unicem and seT. Panavia F showed the lowest values of microshear bonding strength in both periods. In the analysis after 6months there was a significant increase in the microshear bonding strength values for all cements compared to 24hours. Only for RelyX ARC, the increase was not statistically significant. Conclusion: In conclusion, the bond strength depends mainly on the type of resin cement used, and the self-adhesive cements behave similarly to conventional resin cement.

Aim: To evaluate the color stability of acrylic and bis-acrylic resins after immersion in 3 staining solutions. Methods: Forty-eight samples (10 x 2 mm) of each provisional restorative material (Duralay, Dencrilay, Structur 2 and Protemp 4) were fabricated and distributed into four groups (n = 12): G1 – distilled water (control group); G2 – a cola flavored soft drink; G3 – wine and G4 – coffee. The specimens were immersed for seven days at 37°C in the solutions, which were changed every 24 hours. The color of all specimens was measured with a spectrophotometer (VITA Easyshade Advance) before (T0) and after immersion (T1), and the color changes (ΔE) were calculated. Nonparametric Kruskal-Wallis tests were used, followed by Dunn’s test with a significance level of 5%. Results: For the acrylic resins (Duralay and Dencrilay), the largest color change values were obtained in group G4 – coffee, whereas in the bis-acrylic resins (Protemp 4 and Structur 2), the largest color difference was observed in groups G3 – wine and G4 – coffee. The acrylic resins showed statistically significantly less color change than the bis-acrylic resins. Conclusions: The coffee and the wine promoted larger color changes in the provisional prosthetic materials tested in this study. The acrylic resins showed more color stability than the bis-acrylic resins.

Management of non-carious cervical lesions (NCCLs) still is a challenge in clinical practice. The diagnosis is the key to treat these lesions successfully. Aim/Case report: Therefore, the aim of this case report is to describe the diagnosis and treatment of generalized abfraction lesions associated to abrasion lesions of a 43 years old patient and to discuss considerations about the technique and materials to be used appropriately. After the diagnosis, a treatment plan with preventive and restorative approach was elaborated. The occlusal adjustment was performed to distribute the contact points and the patient was instructed in relation to tooth brushing habits. It was also recommended that the patient use a dentifrice with potassium nitrate for the control of sensitivity. For lesions over 1mm deep, the restorative treatment was performed using the self-etching adhesive system and nanohybrid composite by the stratification technique. Unsatisfactory restorations have been replaced. Occlusal splint was done and the patient was instructed to use the device every day overnight. One year after treatment, follow-up was performed. The appearance of new NCCLs was not observed. There was no progression of lesions smaller than 1 mm. There was no loss of restorations. All restorations were fully satisfactory and the patient reported absence of dentin hypersensitivity. Conclusion: The treatment performed besides being aesthetically satisfactory after 1 year resulted in the control of the disease, preventing the appearance of new lesions and guaranteeing a better quality of life to the patient.

Aim: this study aimed to evaluate the degree of conversion (DC) exhibited by novel formulations of dental adhesive systems including camphorquinone (CQ), phenyl-propanedione (PPD), and bis-alkyl phosphine oxide (BAPO) when cured by mono- or polywave light emitting diodes (LEDs). Methods: an adhesive model was formulated by mixing hydroxyethyl methacrylate (HEMA, 40 wt%) and bisphenol A glycidyl dimethacrylate (BisGMA, 60 wt%) in ethanol (30 wt%). Five materials were then formulated by adding the following photoinitiators: CQ (1 mol%), CQ/PPD (0.5/0.5 mol%), CQ/BAPO (0.5/0.5 mol%), PPD (1 mol%), and BAPO (1 mol%). The DC for each material was measured with Fourier transform infrared spectroscopy. Analysis of variance and Tukey’s post-hoc test were used to analyze the data (p < 0.05). Results: Except for CQ, the photoinitiators provided a significantly higher DC in the adhesive systems following photoactivation with a polywave LED. Conclusion: The use of alternative photoinitiators and a polywave LED improved the DC of the adhesive systems examined.

Aim: This study characterized the implant surfaces available on the Brazilian market in terms of topography, chemical composition, and roughness. Methods: The following brands were selected according to their surfaces: Kopp (Ko), Signo Vinces (Sv), Neodent (Ne), Osseotite (Os) NanoTite (Nt), SIN (Si), Titanium Fix (Tf), conventional Straumann (Str), Active SLA (SLA). The morphological analysis and the alloy impurities and implant surface contaminants were analyzed by SEM-EDS. Surface roughness parameters and 3-D reconstructions were obtained by laser microscopy (20x). Two distinct areas were evaluated: i) the cervical portion (no surface treatment), and ii) the middle third (treated surface). Results: The characterization of the implant surfaces by SEM showed morphological differences between the thread geometries and surface morphology at 800x and 2000x magnification. The EDS elemental analysis showed a predominance of titanium (Ti) for all implants. The SLA surface showed only peaks of Ti while other implants brands showed traces of impurities and contaminants including Al, C, PR, F, Mg, Na, Ni, O, P, and SR. The implant surface roughness in the cervical portion did not exceed Ra 0.5–1.0 μm, constituting a minimally rough surface and obtaining acceptable standards for this region. Only Nt, Str, and SLA presented Ra above 2 μm in the middle third area showing a rough surface favorable for osseointegration. Conclusion: This study concluded that there is no established standard for morphology, chemical composition and implant surface roughness that allows a safe comparison between the available dental implant surfaces. National implant brands generally contain more impurities and surface contaminants than their international counterparts and were consequently more sensitive to the surface treatment techniques.
Dos prazeres às interdições urbanas: imagens sensíveis de São Paulo nos contos de Mário de Andrade
Authors: Cardinalli Thainã Teixeira
Published: August 2018

Investigo neste artigo os contos “Primeiro de Maio” e “Atrás da Catedral de Ruão”, que compõem o livro Contos Novos (1947) de Mário de Andrade. Ambas as narrativas retratam a cidade de São Paulo por entre os conflitos pessoais e profissionais das personagens, um carregador de malas da Estação da Luz e uma professora de francês, respectivamente. São histórias que ao descreverem determinados lugares e situações urbanas vivenciadas na capital paulista, revelam a estreita relação entre os contos do literato e os discursos politicos, produções literárias e debates urbanísticos difundidos na primeira metade do século XX, em São Paulo.
Patrimônio cultural potiguar: história, memória e narrativas do presente
Authors: Assunção Gabriela
Published: August 2018

No cenário da Natal contemporânea, o artigo discute os elementos físicos que dão suporte as narrativas do presente sobre sua área patrimonial. As falas de usuários (moradores, trabalhadores e visitantes) dos antigos bairros, Cidade Alta e Ribeira, são analisadas com base no estudo da história e memória local. Entre os resultados, destacou-se a influência dos discursos de modernização de início do século XX ainda presente na forma de interpretar o ambiente urbano. Na imagem apresentada, observa-se dificuldade de os usuários reconhecerem valor de trechos modestos da malha, aqueles fora dos padrões da cidade moderna. Nesse sentido, orientam-se caminhos para ampliar lembranças e apagar imagens negativas associadas ao local.
