Riester reformieren oder revolutionieren – Das ist hier die Frage
Authors: Hagist Christian 
Published: January 2021

Abstract
Considering the aging process in Germany with fewer young people having to finance more elderly, the government coalition aims to make the voluntary but subsidized Riester pension more attractive. This contribution backs the idea of replacing in parts the pay-as-you-go state pension scheme with a funded component and admonishes the urgency of reform. However, two mistakes are pointed out that have been made due to a lack of political courage: Firstly, the contribution guarantee leads to considerable losses in returns and secondly, the voluntary nature of the funded component leads to adverse selection. Since a reform would presumably not induce the desired renaissance, the proposal is to introduce a fully funded mandatory component.

Published: January 2021

Abstract
Increasing knowledge of hybrid nanofluid can be traced to its unique improvement of thermal performance and enhancement of heat transfer rate as applicable in the dynamics of fuel and coolant in automobiles. However, the case of water-based nanofluid conveying three kinds of nanoparticles (i.e., ternary-hybrid nanofluid) with various shapes and densities is far-fetched. The transport phenomena of water conveying smaller densities nanoparticles (i.e., copper nanotubes, graphene, and aluminum oxide) and substantial large densities of nanoparticles (i.e., copper oxide, copper, and silver) of various types through a rectangular closed domain with major emphasis on the significance of suction and dual stretching was investigated. The dimensional equation that model the aforementioned transport phenomenon, for the two cases, were non-dimenzionalized using appropriate similarity variables, parameterized, and solved numerically using shooting techniques together with fourth-order Runge-Kutta integration scheme and in-built bvp4c package of MATLAB. Enhancement in suction and stretching ratio causes the vertical velocity of the motion along x-direction and Nusselt number to be an increasing function. Due to an increase in suction and stretching ratio, fluid flow along (x, y)-directions, temperature distribution, and the local skin friction coefficients are decreasing functions. At all the levels of suction and stretching ratio, higher Nusselt numbers were found in the case of water conveying Copper oxide, Copper, and Silver nanoparticles due to their heavy densities.
Steel fibers for replacing minimum reinforcement in beams under torsion
Authors: Facconi Luca , Minelli Fausto , Ceresa Paola , Plizzari Giovanni 
Published: January 2021

AbstractThis paper concerns an investigation on six large-scale Steel Fiber Reinforced Concrete (SFRC) beams tested in pure torsion. All beams had longitudinal rebars to facilitate the well-known space truss resisting mechanism. However, in order to promote economic use of the material, the transverse reinforcement (i.e. stirrups/links) was varied in the six large scale beams. The latter contained either no stirrups, or the minimum amount of transverse reinforcement (according to Eurocode 2), or hooked-end steel fibers (25 or 50 kg/m3). Material characterization were also carried out to determine the performance parameters of SFRC. The results of this study show that SFRC with a post-cracking performance class greater than 2c (according to Model Code 2010) is able to completely substitute the minimum reinforcement required for resisting torsion. In fact, the addition of steel fibers contributes to significantly increase the maximum resisting torque and maximum twist when compared to the same specimen without fibers. Moreover, SFRC provides a rather high post-cracking stiffness and a steadier development of the cracking process as compared to classical RC elements. This phenomenon improves beam behavior at serviceability limit state. The experimental results are critically discussed and compared to available analytical models as well as with other tests available into the literature.

Published: January 2021

Objetivos: Establecer la influencia del riesgo social en la adherencia terapéutica al tratamiento farmacológico de la diabetes mellitus 2 (DM2) en mayores de 65 años. Método: Estudio descriptivo transversal a partir de las historias clínicas electrónicas de Atención Primaria en personas mayores de 65 años con DM2 de la Dirección Asistencial Norte de Madrid (n=26703). Se realizó análisis multivariante de regresión logística para la No Adherencia al Tratamiento (No AdhT) y para mal control de DM2, desagregado por sexo. Resultados: Un 33,7% tenían mal control de la DM2 y un 3,1% No AdhT. En modelos de regresión para el mal control de la DM2, lo aumentaba la No AdhT (OR: 1,64; IC95%: 1,07-2,51)). En ambos sexos, el riesgo social provoca una mayor falta de adherencia, en mujeres (5.7% vs. 1.9%, p = 0.000), hombres (7.5% vs. 2.3%, p = 0,000). En los modelos de regresión para la no AdhT, la aumentaba tener riesgo social (OR: 2.92, IC 95%: 1.61-5.30) en mujeres; riesgo social (OR = 3.52, IC 95% 1.90-6.52) se asoció con la no adherencia también en hombres. Conclusiones: En los mayores de 65 años con DM2, aunque el No AdhT es bajo, la prevalencia de control deficiente es alta. Para la no AdhT, el riesgo social se presenta como factor de riesgo para ambos sexos, pero tener depresión aumenta la no AdhT en las mujeres y los síntomas de ansiedad en los hombres. Sin AdhT aumenta el riesgo de un control deficiente de DM2, especialmente en mujeres; además de no hacer dieta y tener sobrepeso/obesidad.

Published: January 2021

BackgroundVestibular symptoms and balance disorders are still common complaints reported by the patients after cochlear implantation (CI). Much research has been devoted to assess dizzy patients after cochlear implantation using both self-prepared questionnaires as well as validated life-quality scales. From this work, various approaches to classifying symptoms according to their onset and duration have been recommended.Material and methodsWe studied 101 patients after round window approach (RWA) cochlear implantation giving them a self-prepared questionnaire asking them to list their major vestibular complaints formulated according to the consensus document of the Barany Society Committee for the classification of vestibular disorders. Those with persistent symptoms (both postoperatively and existing preoperatively) also filled in a DHI questionnaire. Additionally, cVEMP, oVEMP, caloric, and vHIT tests were performed before and after the CI procedure.ResultsThe 101 patients were divided into four groups: with early symptoms (n = 25), with late symptoms (n = 2), with preoperative symptoms (n = 13), and with no symptoms (n = 61). Among the patients with early symptoms, 15 reported spontaneous vertigo attack, 6 only unsteadiness and/or lateropulsion, and 4 had other symptoms such as orthostatic vertigo, positional vertigo, visual tilt, and head-motion vertigo.ConclusionsClose to 40% of the CI recipients suffered from vestibular complaints, either in the postoperative period or from already existing preoperative symptoms. The vast majority of postoperative complaints were transient and only rare cases (with preexisting inner ear pathologies and/or comorbidities) evolved into persistent dysfunction.

Background: In treating peri-implantitis, dentists pay attention to drugs that do not contain chemically aggressive agents. They rather use those having natural mechanisms for normalization of the functional activity of cells and tissues in addition to local antiseptic and antibacterial agents.
The aim of the study was to determine the clinical effectiveness of nicotinamide adenine nucleotide hydride dental gel in the treatment of peri-implantitis.
Materials and methods: Depending on the therapeutic tactics patients (n = 40), we divided patients into two groups. In Group 1 (n=20), we used a standard treatment of peri-implantitis including professional hygiene measures, antiseptic treatment and the use of antibacterial agents. In Group 2 (n = 20), the complex treatment included photodynamic effects of 1% photosensitizer gel instead of the antibacterial therapy.
Results: Due to the use of the photodynamic therapy in addition to standard treatment of group 2 patients, the concentration of a tartrate-resistant acid phosphatase in the peri-implantation exudate reached the level of healthy people in the gingival fluid. In addition, the concentrations of cathepsin K and interleukin-6 were as close as possible to the control level.
Conclusion: The use of NADH for peri-implantitis helps to eliminate inflammatory phenomena and stimulates the regeneration of the oral mucosa.

Published: January 2021

Background. This study aimed to improve the clinical effect of dental orthopedic treatment for patients who need a complete dental reconstruction, by making use of the temporomandibular joint characteristics.
Materials and Methods. A total of 647 patients with adentia who needed a complete dental reconstruction were exposed to a comprehensive examination and treatment. Patients were divided into 3 groups: orthopedic rehabilitation group (218 patients), interdisciplinary rehabilitation group (195 patients), and multidisciplinary rehabilitation group (234 patients). The follow-up period was 7 years.
Results. After the proposed rehabilitation approach, patients in the main group demonstrated an improvement in the VAS (Visual Analogue Scale) score, which was significantly smaller with respect to that in the comparison groups. The frequency of clicking and pain during chewing as well as soreness sensations in this group decreased at a significantly lower pace compared to that in the comparison groups.
Conclusions. Dental reconstruction procedures aimed at restoring the shape of the teeth should focus on pain relief and temporomandibular joint function correction. The most important stage in implementing this approach is a complete and consistent examination of patients who need dental reconstruction.

Polypharmacy among older Brazilians: prevalence, factors associated, and sociodemographic disparities (ELSI-Brazil)
Authors: Seixas Brayan V. , Freitas Gabriel R. 
Published: January 2021

Background: Polypharmacy has become an increasingly public health issue as population age and novel drugs are developed. Yet, evidence on low- and middle-income countries (LMIC) is still scarce.
Objective: This work aims to estimate the prevalence of polypharmacy among Brazilians aged 50 and over, and investigate associated factors.
Methods: A cross-sectional study was conducted using data from the baseline assessment of the Brazilian Longitudinal Study of Aging (ELSI-Brazil), a nationally representative study of persons aged 50 years and older (n=9,412). Univariate and bivariate analyses described the sample. Robust Poisson regression was used to estimate prevalence ratios and predict probabilities of polypharmacy.
Results: Prevalence of polypharmacy was estimated at 13.5% among older adults in Brazil. Important disparities were observed in regard to gender (16.1% among women and 10.5% among men), race (16.0% among whites and 10.1% among blacks) and geographic region (ranging from 5.1% in the North to 18.7% in the South). The multivariate analysis showed that polypharmacy is associated with various sociodemographic/individual factors (age, gender, race, education, region, health status, body mass index) as well as with several variables of healthcare access/utilization (number of visits, same physician, provider’s knowledge of patient’s medications, gate-keeper, and difficulty managing own medication). Overall, the more utilization of health services, the higher the probability of polypharmacy, after adjusting for all other model covariates.
Conclusions: Polypharmacy prevalence is relatively low in Brazil, compared to European countries. After controlling for variables of healthcare need and demographic characteristics, there is still substantial residual variance in polypharmacy prevalence. Policies to identify inappropriate prescribing and reduce regional discrepancies are necessary.

La terneza es una característica importante para la comercialización de carne de bovino; el grado de terneza está asociado a factores genéticos como los polimorfismos de nucleótido único (SNPs). El objetivo de este trabajo fue evaluar los SNPs G530A, C357G, G1795A y G1181A como predictores de terneza. Se obtuvieron 90 muestras de musculo longissimus dorsi. La terneza se determinó como fuerza de corte de Warner-Bratzler. La genotipificación de los SNPs se realizó por PCR-RFLP. Se realizó una prueba de asociación entre los SNPs y la terneza mediante un modelo de efectos mixtos. Se determinó que el grupo genético influyó sobre la terneza (P < 0.05). Para el SNP C530A se detectó baja frecuencia del genotipo AA (0.011), de forma similar para el SNP G1181A se obtuvo baja frecuencia para el genotipo AA (0.033), para los SNPs C357G y G1795A se obtuvieron mayores frecuencias para los genotipos ancestrales CC (0.711) y GG (0.20), respectivamente. Los resultados establecieron que no existe influencia de estos SNPs (P > 0.05) sobre la terneza. Esto indica la necesidad de llevar a cabo un análisis de validación de los SNPs de interés, para poder introducirlos de manera favorable mediante programas de selección asistida por marcadores.
