Authors: Trapp Wolfgang , Kilic Oeznur , Röder Susanne , Lautenbacher Stefan , Hajak Göran
Published: September 2019

BACKGROUND

Recently, non-drug treatment options to reduce cognitive decline in dementia have become increasingly prominent. First results from qualitative studies show that tablet-based applications are perceived as attractive by dementia patients.

OBJECTIVE

Attractiveness, validity and usability of a cognitive stimulation app developed for groups of older people were examined using quantitative data.

METHODS

A standardized group session was performed with 20 subjects (10 women, 10 men, 6 controls, 8 patients with mild cognitive impairment and 6 patients with mild dementia), in which four tasks from the tablet-based app as well as four paper and pencil tasks from a validated manual for cognitive activation in patients with mild dementia were administered.

RESULTS

Both types of tasks were rated as little exhausting and very attractive, with three of the four tablet tasks being rated better in terms of attractiveness (P=.017, .008 and .096). Although the majority of tasks was solved more quickly by the participants with lower cognitive deficits (.002 <= P <= .038), the exercises were resolved timely and without problems by all participants from the beginning, and the groups did not differ in their learning progress regarding tablet operating speed (.193 <= P <= .739).

CONCLUSIONS

The findings encourage the use of this low cost and accessible technology. With the BTTB, a ready-to-use application without additional costs or hardware requirements is available, which can be used directly in group sessions with dementia patients.

Published: September 2019

BACKGROUND

Atrial fibrillation (AF), sternal wound infection, and cardiac decompensation are complications that can occur after cardiac surgery. Early detection of these complications is clinically relevant, as early treatment is associated with better clinical outcomes. Remote monitoring with the use of a smartphone (mobile health [mHealth]) might improve the early detection of complications after cardiac surgery.

OBJECTIVE

The primary aim of this study is to compare the detection rate of AF diagnosed with an mHealth solution to the detection rate of AF diagnosed with standard care. Secondary objectives include detection of sternal wound infection and cardiac decompensation, as well as assessment of quality of life, patient satisfaction, and cost-effectiveness.

METHODS

The Box 2.0 is a study with a prospective intervention group and a historical control group for comparison. Patients undergoing cardiac surgery at Leiden University Medical Center are eligible for enrollment. In this study, 365 historical patients will be used as controls and 365 other participants will be asked to receive either The Box 2.0 intervention consisting of seven home measurement devices along with a video consultation 2 weeks after discharge or standard cardiac care for 3 months. Patient information will be analyzed according to the intention-to-treat principle. The Box 2.0 devices include a blood pressure monitor, thermometer, weight scale, step count watch, single-lead electrocardiogram (ECG) device, 12-lead ECG device, and pulse oximeter.

RESULTS

The study started in November 2018. The primary outcome of this study is the detection rate of AF in both groups. Quality of life is measured with the five-level EuroQol five-dimension (EQ-5D-5L) questionnaire. Cost-effectiveness is calculated from a society perspective using prices from Dutch costing guidelines and quality of life data from the study. In the historical cohort, 93.9% (336/358) completed the EQ-5D-5L and patient satisfaction questionnaires 3 months after cardiac surgery.

CONCLUSIONS

The rationale and design of a study to investigate mHealth devices in postoperative cardiac surgery patients are presented. The first results are expected in September 2020.

Smartphone-Guided Algorithms for Use by Community Volunteers to Screen and Refer People With Eye Problems in Trans Nzoia County, Kenya: Development and Validation Study (Preprint)
Authors: Rono Hillary , Bastawrous Andrew , Macleod David , Bunywera Cosmas , Mamboleo Ronald , Wanjala Emmanuel , Burton Matthew
Published: September 2019

BACKGROUND

The provision of eye care services is currently insufficient to meet the requirements of eye care. Many people remain unnecessarily visually impaired or at risk of becoming so because of treatable or preventable eye conditions. A lack of access and awareness of services is, in large part, a key barrier to handle this unmet need.

OBJECTIVE

This study aimed to assess whether utilizing novel smartphone-based clinical algorithms can task-shift eye screening to community volunteers (CVs) to accurately identify and refer patients to primary eye care services. In particular, we developed the Peek Community Screening app and assessed its validity in making referral decisions for patients with eye problems.

METHODS

We developed a smartphone-based clinical algorithm (the Peek Community Screening app) using age, distance vision, near vision, and pain as referral criteria. We then compared CVs’ referral decisions using this app with those made by an experienced ophthalmic clinical officer (OCO), which was the reference standard. The same participants were assessed by a trained CV using the app and by an OCO using standard outreach equipment. The outcome was the proportion of all decisions that were correct when compared with that of the OCO.

RESULTS

The required sensitivity and specificity for the Peek Community Screening app were achieved after seven iterations. In the seventh iteration, the OCO identified referable eye problems in 65.9% (378/574) of the participants. CVs correctly identified 344 of 378 (sensitivity 91.0%; 95% CI 87.7%-93.7%) of the cases and correctly identified 153 of 196 (specificity 78.1%; 95% CI 71.6%-83.6%) cases as not having a referable eye problem. The positive predictive value was 88.9% (95% CI 85.3%-91.8%), and the negative predictive value was 81.8% (95% CI 75.5%-87.1%).

CONCLUSIONS

Development of such an algorithm is feasible; however, it requires considerable effort and resources. CVs can accurately use the Peek Community Screening app to identify and refer people with eye problems. An iterative design process is necessary to ensure validity in the local context.
The Convolution Neural Network Combined with the HT Person Fit Statistic to Develop an APP for Detecting Dengue Fever in Children: Development and Usability Study (Preprint)
Authors: WEI CHIEN , Julie Chi Chow , Willy Chou
Published: September 2019

UNSTRUCTURED

Backgrounds: Dengue fever (DF) is an important public health issue in Asia. However, the disease is extremely hard to detect using traditional dichotomous (i.e., absent vs. present) evaluations of symptoms. Convolution neural network (CNN), a well-established deep learning method, can improve prediction accuracy on account of its usage of a large number of parameters for modeling. Whether the HT person fit statistic can be combined with CNN to increase the prediction accuracy of the model and develop an application (APP) to detect DF in children remains unknown. Objectives: The aim of this study is to build a model for the automatic detection and classification of DF with symptoms to help patients, family members, and clinicians identify the disease at an early stage. Methods: We extracted 19 feature variables of DF-related symptoms from 177 pediatric patients (69 diagnosed with DF) using CNN to predict DF risk. The accuracy of two sets of characteristics (19 symptoms and four other variables, including person mean, standard deviation, and two HT-related statistics matched to DF+ and DF−) for predicting DF, were then compared. Data were separated into training and testing sets, and the former was used to predict the latter. We calculated the sensitivity (Sens), specificity (Spec), and area under the receiver operating characteristic curve (AUC) across studies for comparison. Results: We observed that (1) the 23-item model yields a higher accuracy rate (0.95) and AUC (0.94) than the 19-item model (accuracy = 0.92, AUC = 0.90) based on the 177-case training set; (2) the Sens values are almost higher than the corresponding Spec values (90% in 10 scenarios) for predicting DF; (3) the Sens and Spec values of the 23-item model are consistently higher than those of the 19-item model. An APP was subsequently designed to detect DF in children. Conclusion: The 23-item model yielded higher accuracy rates (0.95) and AUC (0.94) than the 19-item model (accuracy = 0.92, AUC = 0.90). An APP could be developed to help patients, family members, and clinicians discriminate DF from other febrile illnesses at an early stage.

Ser sociólogo/a: la habitual costumbre de la interrogación permanente
Authors: Valencia García Guadalupe
Published: September 2019

En el presente artículo se realiza una reflexión en torno al quehacer del sociólogo en la actualidad. Para ello se tomaron como ejes de análisis tres preguntas fundamentales: el por qué, el cómo y el para qué de la sociología, pues consideramos que la interrogación permanente sobre estas cuestiones es lo que permite la construcción del ser sociólogo.  Plantear la cuestión de la interrogación permanente como condición de posibilidad de la disciplina permite contribuir al debate actual para dilucidar, desde una óptica amplia pero exigente, los problemas de su porvenir en el marco interpretativo de lo social y temporal.
Hacia una sociología unificada: la falsa disputa entre utilidad cognitiva y utilidad práctica
Authors: Ascensio Martínez Christian Amaury
Published: September 2019

En este artículo reflexiono sobre el “por qué”, el “para qué” y el “cómo” de la sociología y para ello sostengo una postura dual sobre la relevancia de esta disciplina en el siglo XXI. Por un lado, la centralidad de una orientación cognitiva basada en la formulación de preguntas propias del campo académico y su tratamiento rigurosamente científico; y por otro, la importancia de una formación profesional que permita a los expertos participar activamente en los debates que agitan la vida social, así como comprender e incidir en la resolución de los problemas sociales y en el diseño e implementación de políticas públicas. Considero que la disputa entre la utilidad cognitiva y la utilidad práctica es resoluble, dado que el conocimiento científico favorece la implementación de intervenciones sociales efectivas y proporciona insumos para un quehacer político de carácter estratégico.
Heat-Bath Algorithmic Cooling with optimal thermalization strategies
Authors: Alhambra Álvaro M. , Lostaglio Matteo , Perry Christopher
Published: September 2019

Heat-Bath Algorithmic Cooling is a set of techniques for producing highly pure quantum systems by utilizing a surrounding heat-bath and unitary interactions. These techniques originally used the thermal environment only to fully thermalize ancillas at the environment temperature. Here we extend HBAC protocols by optimizing over the thermalization strategy. We find, for any d-dimensional system in an arbitrary initial state, provably optimal cooling protocols with surprisingly simple structure and exponential convergence to the ground state. Compared to the standard ones, these schemes can use fewer or no ancillas and exploit memory effects to enhance cooling. We verify that the optimal protocols are robusts to various deviations from the ideal scenario. For a single target qubit, the optimal protocol can be well approximated with a Jaynes-Cummings interaction between the system and a single thermal bosonic mode for a wide range of environmental temperatures. This admits an experimental implementation close to the setup of a micromaser, with a performance competitive with leading proposals in the literature. The proposed protocol provides an experimental setup that illustrates how non-Markovianity can be harnessed to improve cooling. On the technical side we 1. introduce a new class of states called maximallyactivestates and discuss their thermodynamic significance in terms of optimal unitary control, 2. introduce a new set of thermodynamic processes, called β-permutations, whose access is sufficient to simulate a generic thermalization process, 3. show how to use abstract toolbox developed within the resource theory approach to thermodynamics to perform challenging optimizations, while combining it with open quantum system dynamics tools to approximate optimal solutions within physically realistic setups.

Published: September 2019

En México, en la década de 1990 se crean los primeros refugios para mujeres vícitmas de violencia con el fin de atenderlas y darles un lugar donde vivir al momento de huir de su agresor. Se diseñaron estrategias para atenderlas de manera integral pero, en un inicio no se pensó en sus hijos e hijas, quienes llegaban con ellas al refugio y sólo se les entretenía mientras psicólogas y trabajadoras sociales atendían a sus madres. Ahora, ante la necesidad de proteger a la comunidad infantil en situación de refugio, empiezan a diseñanse estrategias para dar seguimiento y atención a estos menores que antes eran ignorados como víctimas.

Published: September 2019

La formación inicial debe tratar de acercar a los futuros docentes el conocimiento de los contextos reales educativos. Aun así, el maestro se puede encontrar con realidades para las que no ha sido formado. Ante esta situación, la reflexión crítica se erige como fundamental para poder subsanar las dudas y problemáticas que pueden surgir a un maestro novel. En este artículo se presenta, con una metodología autobiográfica, el modo en que un maestro novel de Educación Física se enfrenta a las consecuencias derivadas de tener que desempeñar su profesión en la etapa de Educación Infantil, una etapa para la que no se siente preparado ni cree haber tenido la suficiente formación específica como maestro de Educación Física. A través de la reflexión crítica y el diario de clase, el docente va reconstruyendo su identidad profesional al comenzar a analizar, reflexionar y poner en duda muchas de las cosas que hace y el modo en que las hace.

Triangulación de métodos e instrumentos de evaluación en Educación Superior
Authors: Cintas Gómez Aroa
Published: September 2019

En términos pedagógicos, los planteamientos multivariados en cuanto a los instrumentos, técnicas y métodos de recogida de información son claves para poder tener una perspectiva holística del proceso de enseñanza, aprendizaje del estudiantado y la comprobación de la adquisición de competencias requeridas. Desde un paradigma tradicional, la evaluación del aprendizaje se constituye por la evaluación de los conocimientos adquiridos y de una forma unidireccional del profesor hacia el estudiante. Sin embargo, el proceso de convergencia EU lleva consigo una serie de cambios en la misión de la universidad en cuanto al proceso de enseñanza y aprendizaje de los estudiantes. La educación superior está enfocada a nuevo planteamiento pedagógico donde el alumno ya no es un stakeholder pasivo, sino activo en su propio proceso de enseñanza y aprendizaje. La siguiente comunicación, presentará el plan evaluativo configurado por múltiples metodologías de evaluación e instrumentos conforme a las competencias requeridas del Proyecto Transversal que se realizó en el Grado oficial en Ostelea.

Análisis de las competencias y conocimientos de los estudiantes empresariales mediante el empleo de la estrategia activa de aprendizaje “mapas conceptuales”
Authors: Sandoval Hamón Leyla Angélica
Published: September 2019

En el Espacio Educación Superior Europea (EEES), los estudios de titulación oficial deben fomentar las competencias y el conocimiento de los estudiantes. Esta experiencia se basa en la estrategia activa de aprendizaje (mapas conceptuales) donde los estudiantes analizan, sintetizan y resumen los temas propuestos en clase, con el fin de mejorar sus conocimientos y habilidades. Por lo tanto, este trabajo describe la experiencia de aplicar la estrategia "mapas conceptuales" en el tema de "Fundamentos de la Administración de Empresas" en el primer semestre del año académico 2018-2019. La implementación de esta experiencia requirió una revisión de los temas, su seguimiento y evaluación. Las conclusiones (derivadas del análisis de datos de cuestionarios de competencia y pruebas de conocimiento) indican que este tipo de estrategia aumenta la comprensión de los conceptos básicos que se enseñan sobre la materia mencionada anteriormente, pero no aumenta la competencia de los estudiantes sobre la materia.

O Cafe é o Novo Ovo? Publicização Jornalística das Notícias que Relacionam Café e Saúde
Authors: Teixeira Lucas de Vasconcelos , Hoff Tânia Márcia Cezar
Published: September 2019

Este artigo tematiza a relação alimentação e saúde sob a perspectiva comunicacional, especialmente a circulação de uma agenda positiva de notícias, que modifica o regime de visibilidade do café em um contexto midiático de gourmetização de alimentos. Temos como objetivo refletir sobre a produção de sentidos atribuídos ao café nos discursos midiáticos, à luz da noção de biossociabilidades do consumo. Os estudos de comunicação e consumo articulados a Análise de discurso francesa são mobilizados para examinar o corpus composto por reportagens sobre café coletadas pela newsletter da Cecafé. Os resultados indicam que a lógica capitalista contemporânea altera os vínculos de sentido, instaurando que a gestão de si voltada para produtividade e performance é também aplicada às práticas alimentares e materializada em notícias publicizadas que refletem e refratam o que se espera do sujeito neoliberal.
Deu Zika na Rede: uma análise sobre a produção de sentidos sobre a Epidemia de Zika e Microcefalia no Facebook
Authors: Garcia Marcelo Pereira , Cardoso Janine Miranda
Published: September 2019

A circulação de boatos virtuais marcou a epidemia de zika e microcefalia de 2015/2016. A partir da análise dos comentários de posts das páginas do Diário de Pernambuco e da Folha de S. Paulo no Facebook, visamos compreender melhor o fenômeno, identificando discursos mobilizados nesses espaços intertextuais e polifônicos. Os resultados evidenciam um ambiente de incerteza associado ao desconhecimento científico, à crise política e à reflexividade em relação aos riscos da ciência. Também apontam questões não respondidas que estimularam a circulação dos boatos: Por que a epidemia se concentrou em Pernambuco? Por que nunca ocorreu na África? Por que não aconteceu antes? Concluímos que o enfraquecimento do estatuto de verdade da ciência e da própria verdade, mais fluida, participa do protaganismo do boato na atualidade midiatizada.

Authors: De Sá Medeiros Haroldo , Paes de Souza Mariluce , Paiva Maciel Larissa Ananda
Published: September 2019

Among the main changes in daily life that are due to the use of online tools, the search for information to help the purchasing decision process was one of the most impacted. Before the popularization of Internet use, positive and negative information about products and services was obtained in small groups of individuals. After popularization, the interactivity between users grew and extended to consumer practices, generating a word-of-mouth communication in electronic media. In this way, this article aims to assess comparatively the influences of the positive and negative electronic mouth-to-mouth communication in the online purchasing decision process. For this, 248 questionnaires were applied and ten hypotheses were verified. As analytical methods were used the descriptive statistic and the confirmatory factorial analysis by means of structural equations. Only the evaluation of alternatives, purchase and post-purchase behavior are influenced.
CLIENTE: um novo fator de produção
Authors: Fernandes José Luiz Nunes
Published: September 2019

Tradicionalmente, os fatores de produção são as matérias-primas, mão de obra e os gastos gerais de fabricação, porém contemporaneamente reconhece-se a presença do cliente no processo produtivo, o que autores convencionaram chamar de cocriação de valor, ou seja, criação conjunta, empresa e cliente. Desse modo, a pesquisa teve como objetivo investigar o correto tratamento dos recursos consumidos por meio da composição dos custos com clientes presentes no processo contemporâneo de produção. Para o alcance do objetivo, buscou-se por meio de estudos bibliográficos e documentais evidenciar estudos reais onde a cocriação de valor está presente e correlacioná-los com a teoria subjacente. A pesquisa concluiu que, quanto à presença dos clientes no processo produtivo, os custeios tradicionais ainda não tiveram a percepção e o tratamento adequado, fato que não acontece com o custeio contemporâneo denominado de Custeio Baseado em Atividades.
Pathogenetic Substantiation of the Therapeutic Impact on Microbiota in Irritable Bowel Syndrome
Authors: Shulpekova Yu. O. , Babaeva G. H. , Rusyaev V. Yu.
Published: September 2019

Aim. This review aims to describe the nature of changes in the intestinal microbiota in irritable bowel syndrome (IBS) and provide a pathogenetic justification of the feasibility of a therapeutic impact on microbiota. 

General findings. An important aspect of the interaction of intestinal bacteria with the “host” cells is their contact with pattern recognition receptors of enterocytes, dendritic cell receptors, as well as a transcellular transport of antigens in the region of Peyer’s patches. The area of interaction of intestinal bacteria and the human body is not limited to the intestines. Intestinal bacteria demonstrate a significant humoral effect due to signalling molecules, some of which exhibit neurotransmitter properties. The study of the bacterial cross-feeding for various species, i.e. mutual use of nutrient substrates produced by bacteria of various species, is of a great interest. The development of a lowactivity inflammation in IBS can partly be explained by the increased interaction of flagellin with the corresponding receptor, as well as the influx of excess bacteria from the small intestine. The majority of studies on IBS have demonstrated the predominance of intestinal bacteria with pro-inflammatory potential (Enterobacteriaceae) and the lack of bacteria with a pronounced anti-inflammatory, antimicrobial and enzymatic action (Lactobacillus and Bifidobacterium), as well as increased mucus degradation. Similar changes are observed in inflammatory bowel diseases. Reduced microbial diversity increases susceptibility to intestinal infections and parasitoses, including those caused by protozoa conditionally pathogenic for adults, such as Blastocystis hominis hominis, Dientamoeba fragilis, Giardia lamblia. With the help of nutrition correction, the use of probiotics and functional foods containing certain probiotic strains, plant fibres (primarily psyllium) and, in some cases, nonabsorbable antibiotics, a positive effect can be achieved in a significant number of IBS patients. Recent works have shown that clinical improvement is accompanied by a change in the composition of the intestinal microbiota.

Conclusion. For the pathogenetic treatment of irritable bowel syndrome, the use of non-drug treatment is justified, such as diet optimization and prescription of plant fibres and probiotic bacterial strains. The positive effect of such an approach is largely determined by modification of the intestinal microbiota composition. This opens up prospects for a further, more targeted impact on the intestinal microbiome.
Implementasi Load Balancing Menggunakan Metode Equal Cost Multi Path (ECMP) Pada Interkoneksi Jaringan
Authors: Anwar Muhammad Khoirul , Nurhaida Ida
Published: September 2019

Internet merupakan kebutuhan yang penting digunakan dalam sebuah perusahaan. Koneksi internet yang digunakan dalam perusahaan harus stabil dan terhindar dari segala macam gangguan. Sebagian besar perusahaan sudah menggunakan dua link koneksi internet yang berguna untuk kelangsungan bisnis perusahaan. Penggunaan dua link koneksi tersebut tidak diimbangi dengan penerapan teknik load balancing dan failover. Pada penelitian ini masalah yang diangkat adalah penerapan load balancing yang sesuai dengan kebutuhan untuk mengoptimalkan kedua link koneksi internet. Metode load balancing yang digunakan adalah Equal Cost Multi Path (ECMP). Selain digunakan untuk membagi beban trafik pada kedua link, load balancing dengan metode ECMP juga dapat memberikan efek failover. Dalam penelitian ini implementasi diterapkan pada dua divisi yaitu divisi Customer Support Engineer (CSE) dan Customer Accounting Executive (CAE) yang terdapat di  PT. Cyberindo Aditama. Hasil pengujian menunjukkan bahwa load balancing dengan metode ECMP dapat menggunakan link koneksi internet secara bergantian sehingga dapat mendistribusikan beban trafik secara merata pada kedua link sedangkan efek failover dihasilkan jika salah satu link terputus maka beban trafik akan secara otomatis berpindah ke link koneksi lain yang masih aktif. Berdasarkan pengamatan yang dilakukan saat terjadi load balancing diperoleh bahwa divisi CSE memiliki throughput 99.96% (sangat bagus), delay 1.70 ms (sangat bagus), dan jitter 0.02 ms (sangat bagus) sedangkan divisi CAE memiliki throughput 99.92% (sangat bagus), delay 1.69 ms (sangat bagus), dan jitter 0.01 ms (sangat bagus).

Introduction/Objective. Biofilm and pyocyanin production are essential components of Pseudomonas aeruginosa virulence and antibiotic resistance. Our objective was to examine inhibitory effect of synthetized propafenone derivatives 3-(2-Fluorophenyl)- 1-(2- (2-hydroxy-3-propylamino-propoxy)-phenyl)-propan-1-one hydrochloride (5OF) and3-(2- Trifluoromethyl-phenyl)-1-(2-(2-hydroxy-3-propylamino-propoxy)-phenyl)-propan-1-one hydrochloride (5CF3) on biofilm and pyocyanin in Pseudomonas aeruginosa clinical strains. Methods. Effects were tested on nine clinical isolates and one control laboratory strain of P. aeruginosa. In vitro analysis of biofilm growing was performed by incubating bacteria (0.5 McFarland) with 5OF and 5CF3 (500?31.2 ?g/ml) and measuring optical density (OD) at 570 nm. Bacteria in medium without compounds were positive control. Blank medium (an uninoculated medium without test compounds) was used as negative control. Pyocyanin production was estimated by OD at 520 nm, after bacteria incubated with 5CF3 and 5OF (250 and 500 ?g/ml), treated with chloroform, and chloroform layer mixed with HCl. Results. A total of 500 ?g/ml of 5OF and 5CF3 completely inhibited biofilm formation in 10/10 and 4/10 strains, respectively. A total of 250 ?g/ml of 5OF and 5CF3 strongly inhibited biofilm formation in 7/10 strains, while inhibition with 125 ?g/ml of 5OF and 5CF3 was moderate. Lower concentrations had almost no effect on biofilm production. Pyocyanin production was reduced to less than 40% of the control value in 6/9, and less than 50% of the control in 7/9 strains with 500 ?g/ml of 5OF and 5CF3, respectively. At 250 ?g/ml 5OF and 5CF3, most strains had pyocyanin production above 50% of the control value. Conclusion. Synthetized propafenone derivatives, 5OF and 5CF3, inhibited biofilms and pyocyanin production of Pseudomonas aeruginosa clinical strains. Presented results suggest that propafenone derivatives are potential lead-compounds for synthesis of novel antipseudomonal drugs.
Mineral trioxide aggregate for the treatment of external root resorption in an avulsed immature tooth - ten years of follow-up
Authors: Peric Tamara , Markovic Dejan , Petrovic Bojan
Published: September 2019

Introduction. Root resorption may occur as a consequence of avulsion injury and may lead to the progressive loss of tooth structure. The aim was to report the outcome of root resorption treated with mineral trioxide aggregate in a replanted immature permanent incisor after 10 years of follow-up. Case outline. This case presents external root resorption that was detected 18 months after the avulsion injury in a nine-year-old child. Apical portion of the canal was filled with mineral trioxide aggregate and the rest of the canal was filled with a canal sealer and gutta-percha. Control examinations were performed six months after the completion of the endodontic treatment and afterwards yearly. The tooth was asymptomatic clinically and radiographs did not show progression of root resorption up to four years of follow-up. Infraposition of the injured tooth was detected five years after the replantation, but without significant radiographic changes, until the eight-year follow-up, when root resorption was detected again. However, the tooth was still hard and symptomless at the 10-year follow-up. Conclusion. Mineral trioxide aggregate may have an important role in the preservation of replanted immature teeth for a prolonged period.
Difference in fertility between women with and without tertiary education in Serbia
Authors: Miric Natalija
Published: September 2019

This paper points to the relative importance of childlessness (childlessness
effect), postponement of motherhood to later ages (age composition effect),
and fertility rates conditional upon age at entry into motherhood (rates
effect) in explaining overall difference in the level of fertility between
women with and without tertiary education. The author estimates these
indicators for three age cohorts, 45-49, 50-54, and 55-59, and thus show
whether and how the relative contribution of these three effects has changed
over time. The decomposition method based on the data from the Census of
Population, Households and Dwellings (2011) is used in this paper. The
results indicate that the difference in fertility between women with and
without tertiary education is 0.35, on average for the analyzed age cohorts.
Decomposition method shows that childlessness effect and age composition
effect have significantly contributed with over 80% to this difference. This
finding suggests that postponing of childbearing among women with tertiary
education has a continuous, dominant importance in the deterministic basis
of the educational differentiation of fertility. On the other side, a weaker
rates effect (20-23%) is evident in all age cohorts. Reason for this is an
absence of fertility recuperation among women with tertiary education (in
contrary to some European countries), thus reflecting the same (not so
favorable) socio-economic and institutional context of life in which all
women realize reproduction.
Post-gel shrinkage, elastic modulus, and stress generated by orthodontic adhesives

Published: September 2019

Objectives:

To measure post-gel shrinkage, elastic modulus, and flexural strength of orthodontic adhesives and to predict shrinkage stress using finite element analysis (FEA).

Materials and Methods:

The following 6 orthodontic adhesives were tested: Transbond XT (3M Unitek, Monrovia, Calif), Transbond Plus Color Change (3M Unitek), Greengloo (Ormco, Brea, Calif), Ortho Connect (GC America, Alsip, Ill), Trulock (RMO, Denver, Colo), GoTo (Reliance, Itasca, Ill). Post-gel shrinkage was measured using a biaxial strain gauge during light curing. Elastic modulus and flexural strength were measured with a 4-point bending test. Analysis of variance and Student-Newman-Keuls post hoc tests were used to compare the shrinkage, elastic modulus, and flexural strengths among the materials (α = .05). Shrinkage stresses caused by the post-gel shrinkage and elastic modulus values were calculated using a cross-sectional FEA of a metallic bracket bonded to an incisor.

Results:

Properties were highly different among the adhesives (P ≤ .0001). Transbond XT (0.38 ± 0.09 percent volumetric contraction) and GoTo (0.42 ± 0.05 percent volumetric contraction) had the lowest post-gel shrinkage; Transbond Plus Color Change had the highest (0.84 ± 0.08 percent volumetric contraction). OrthoConnect (6.8 ± 0.6 gigapascals) had the lowest elastic modulus; GoTo (28.3 ± 3.1 gigapascals) had the highest. Trulock (64.1 ± 8.2 megapascals) had the lowest flexural strength; Greengloo (139.1 ± 20.7 megapascals) had the highest. FEA showed that the highest shrinkage stresses were generated with Transbond Plus Color Change and the lowest with OrthoConnect.

Conclusions:

Post-gel shrinkage of orthodontic adhesives was comparable with restorative composites, which are known to create shrinkage stresses in restored teeth. FEA indicated that this shrinkage creates stresses in the adhesive and in the enamel around the brackets.
Long-term Effects of Disasters on Seniors With Diabetes: Evidence From Hurricanes Katrina and Rita

OBJECTIVE

To estimate the long-run mortality effects of Hurricanes Katrina and Rita on seniors with diabetes.

RESEARCH DESIGN AND METHODS

We performed a retrospective cohort analysis of Medicare enrollment and claims data covering four states and ∼10 years. Affected individuals were identified by whether they lived in a county that suffered a high impact and were stratified by whether they moved to a different county following the storms. Propensity scores matched affected and comparison subjects based on demographic and socioeconomic characteristics and the presence of chronic conditions. Our sample consisted of 170,328 matched affected subjects.

RESULTS

The affected subjects had a nearly 40% higher all-cause mortality risk in the 1st month after the storms, but the difference fell to <6% by the end of the full observation period. The mortality risks of heart disease and nephritis also exhibited the largest differences immediately following the storms. Among the affected subjects, the all-cause mortality risk was higher for those who moved to a different county, with an especially large difference among those who moved to an affected county.

CONCLUSIONS

The propensity matching procedure resulted in the comparison and affected groups having similar observable characteristics. However, we only examined the extreme outcome of mortality, our definition of affected was somewhat crude, and our sample did not include individuals enrolled in Medicare Advantage. Our findings highlight the importance of the immediate response to disasters, yet also demonstrate the long-lasting impact disasters can have.
