Authors: Robayo Adriana Del Rosario Pineda , Felicetti Vera Lucia 
Published: July 2018

Na atualidade, a reflexão pedagógica sobre educação, parece apontar, de diferentes lugares, para o estudo do que ocorre no microcosmo da sala de aula e mais especificamente com as práticas docentes. O objetivo deste artigo é compreender a importância da inclusão de processos de apoio pedagógico por meio de estratégias lúdicas desenvolvidas na hora do conto sobre a prática pedagógica de professores. A metodologia é qualitativa e a partir da perspectiva da Análise Textual Discursiva, se questiona sobre a reflexibilidade de quatro professores de uma escola pública de Porto Alegre no Brasil. Estes participaram de um processo de apoio em sala de aula estruturado como parte do Projeto Biblioteca Viva: espaço de apoio ao ensino e aprendizagem. Os resultados mostram que o apoio educacional, por meio de interações lúdicas se consolidada como espaço altamente valorizado pelos professores, na medida em que facilita, de uma forma prática e experimental, o resignificar, o reaprender, o lembrar-se e observar suas práticas de ensino, tanto em uma dimensão pessoal e de autoconhecimento como também de uma forma interativa, relacional e potencializadora para a aprendizagem de seus alunos.
TRODAT SPECT in patients with idiopathic REM sleep behaviour disorder
Authors: Rizzo Geraldo Nunes Vieira 
Published: July 2018

Objective to determine the value of dopamine transporter (DAT) neuroimaging radiotracer in a group of idiopathic rapid eye movement sleep behavior disorder (iRBD) patients regarding the development of a synucleinopathy. Methods: 6 retrospectively selected patients with clinical and polysomnographic diagnosis of iRBD, on treatment or not, were submitted to a single-photon emission computerized tomography (SPECT) with TRODAT. Results: Five from six patients have an abnormal test showing reduction in DAT density measured by the linkage potential on SPECT. Conclusions: TRODAT crosses the blood brain barrier, has a high affinity for DAT and is capture by SPECT. The decreased uptake of DAT tracers means a reduction in dopaminergic activity which suggest the possibility of Parkinson Disease. We have tried to reinforce iRBD as a marker of neurodegenerative disease and suggest SPECT with TRODAT as an easy method in our country to follow longitudinally these patients.

Introduction The seasonal pattern for mood and behaviour, the behavioural trait of morningness-eveningness, and sleep are interconnected features, that may serve as etiological factors in the development or exacerbation of medical conditions. Methods: The study was based on a random sample of inhabitants aged 25 to 74 years living in Finland. As part of the national FINRISK 2012 study participants were invited (n=9905) and asked whether the doctor had diagnosed or treated them during the past 12 months for chronic diseases.Results: A total of 6424 participants filled in the first set of questionnaires and 5826 attended the physical health status examination, after which the second set of questionnaires were filled. Regression models were built in which each condition was explained by the seasonal, diurnal and sleep features, after controlling for a range of background factors. Of the chronic diseases, depressive disorder was associated with longer total sleep duration (p<.0001) and poor sleep quality (p<.0001). Of the measurements for health status assessment, none associated with sleep features, but systolic blood pressure yielded significant (p<.0001) associations with both seasonal and diurnal features at large. Conclusion: Sleep quality was the most sensitive probe in yielding associations with chronic diseases in this population-based study. The seasonal variations in mood and social activity, and the ease in getting up and tiredness in the morning were the most sensitive probes in yielding associations with blood pressure and waist circumference. Assessment of sleep quality, seasonal and diurnal features provides thus added value for health surveys of the general population.

Published: July 2018

Introduction Hysterectomy is a common gynecologic surgery carried out to remove the pathologic uterus. Objective: To establish if sleep disorders and sexual function are associated with deterioration of the quality of life (QoL) in hysterectomized and sexually active women. Methods: A cross-sectional study was carried out with inhabitants from two cities of the Colombian Caribbean. The pollsters invited women aged between 40-59 years to participate; in their communities they applied surveys with demographic characteristics: Female Sexual Function Index, Atenas Insomnia Scale and Menopause Rating Scale. Sexually active women were selected; then the association was established with logistic regression. Results: 522 women were studied with an average age of 50 years: 30% oophorectomized, 59.8% Hispanic, 40.2% afro-descendants and 22.2% hormonal therapy users. 80% of them had somato/vegetative, psychological or urogenital deterioration; 29.1% with severe deterioration of QoL and 47.5% with insomnia. Out of 390 (74.7%) with sexual activity, 59.7% suffered from sexual dysfunction. Insomnia: OR:3.05 [95%CI:1.86-4.99], sexual dysfunction OR:3.52 [95%CI:2.01-6.17], dissatisfaction about sexuality OR:4.77 [95%CI:2.08-10.93], low or non-existent sexual desire OR:2.94 [95%CI:1.65-5.25], daytime drowsiness OR:3.15 [95%CI:1.59-6.24] and decrease in daytime well-being OR:3.18 [95%CI:1.79-5.64]. These were factors associated with severe worsening of QoL, while the presence of genital lubrication was protective, OR: 0.44 [95%CI:0.21-0.93],p=0.0332. Conclusion: It was observed that insomnia and sexual dysfunction behaved as factors associated with three times more severe deterioration of the QoL in climacteric and sexually active women previously hysterectomized.

Background Sleep disorder is associated with poor quality of life in old age. Therefore, it is imperative to identify contributing factors leading to sleep disorder. The current study aimed to examine the impact of urinary incontinence on sleep complaint after controlling for potential sociodemographic and health covariates. Materials and Methods: A cross-sectional study was conducted on a sample of 184 community dwelling older adults 60 years and older in Yazd, Iran, 2016. In order to obtain the sample a multistage proportional random sampling technique was employed. Sociodemographic characteristics, sleep complaint, and urinary incontinence were collected from medical records. Statistical analyses were performed using SPSS version 24. A multiple logistic regression analysis was used to examine the impact of urinary incontinence on sleep complaint after controlling for potential covariates.Findings: A total of 184 respondents with a mean age of 68.48±6.65 years (age range, 60-87 years) were included in the study. About 70% of the respondents were women, 72.8% were married, 68.5% were not formally educated, and 21.7% were living alone. The prevalence of sleep complaint and urinary incontinence were 27.2% (95% CI: 21-34) and 22.3% (95% CI: 17-29), respectively. The results of the multiple logistic regression analysis revealed respondents with urinary incontinence were four times more likely to suffer from sleep complaint than those without urinary incontinence after adjusting for potential covariates (AOR=4.04, 95% CI: 1.74-9.35,p<0.001). Conclusion: Based on the results of this present study, which showed that urinary incontinence independently contributed to sleep complaint among older adults, it is necessary to employ effective interventions for controlling urinary incontinence to reduce sleep complaints.

Objectives To assess the oral findings of patients who screen high and no risk for obstructive sleep apnea (OSA) reporting to outpatient department of a dental college. Methods: Patients coming to dental Out Patient Department (OPD) were screened using STOP questionnaire and were categorized into high (n=130) and no risk (n=130) OSA groups. BANG (body mass index, age, neck circumference and gender) was recorded for both the OSA risk group patients. Following this oral and general examination was performed using predetermined criteria for temporomandibular disorder (TMD), Angle’s Class of Malocclusion, maxillary arch constriction, facial profile, Mallampati score for uvula, tongue size, depth of palatal vault and periodontitis. Chi-squared statistics was applied to know the significant difference among the two groups. Multivariate logistic regression model was run by including the significant variables.
Results: 94 females and 166 males were present in the study with a mean age of 43.67±11.89 in both the risk groups. All the variables except Angle’s class of malocclusion and periodontitis showed significant difference among high and no risk OSA groups. Logistic regression confirmed that neck circumference, Class 3 or 4 Mallampati score, large tongue and deep palatal vault were commonly observed among high risk OSA group and were independent risk factors for developing high risk of OSA. Conclusion: Neck circumference>40cm, large tongue, Class 3 or 4 Mallampati score and deep palatal vault were found to be independent predictors of developing high risk of OSA. Dentist can play a vital role in screening such patients as he comes in close vicinity of oral cavity and thus can refer the patients to sleep physician to promote interdisciplinary approach.
Effect of hydroxyl groups in NiO
x
on the
open circuit voltage of lead iodide perovskite solar cells

Abstract
The effect of NiO
x
(0 < x) hole
transport layer prepared by a radio-frequency sputtering method on the
photovoltaic properties of planer-type
CH3NH3PbI3 perovskite solar cells (PVSCs)
was investigated. The open circuit voltage of PVSC decreases with increasing
applied power of the sputtering machine. The lack of hydroxyl groups on the
surface of the metal oxides shifts the work function (WF) to
higher energy levels. The X-ray photoelectron peaks of Ni 2p3/2 at
855.6 eV and O 1s at 531.3 eV assigned to ONi(OH) decrease with the increasing
power. Therefore, the decrease in the number of hydroxyl groups must have
shifted the WF to higher energy levels. The shunt resistance of
current–voltage curve and the internal quantum efficiency of the PVSCs is
independent of NiO
x
prepared at various powers.
Assuming that the recombination effect can be neglected, the open circuit
voltage (V
OC) decrease with increasing power is due
to the shifted WF to higher energy levels.
Linkages between soil carbon, soil fertility and nitrogen fixation inAcacia senegalplantations of varying age in Sudan

Published: July 2018

BackgroundOver the last decades sub-Saharan Africa has experienced severe land degradation and food security challenges linked to loss of soil fertility and soil organic matter (SOM), recurrent drought and increasing population. Although primary production in drylands is strictly limited by water availability, nutrient deficiencies, particularly of nitrogen (N) and phosphorus (P), are also considered limiting factors for plant growth. It is known that SOM (often measured as soil organic carbon (SOC)) is a key indicator of soil fertility, therefore, management practices that increase SOM contents, such as increasing tree cover, can be expected to improve soil fertility. The objectives of this study were to investigate the effect ofAcacia senegal(Senegalia senegal) trees on soil nitrogen, phosphorus and potassium (K) in relation to SOC, the potential ofA. senegalfor N2fixation, and to identify possible N and P ecosystem limitations.MethodsSoil nutrient (total N, P, K and available P and exchangeable K) concentrations and stocks were determined for the 0–10, 10–20,20–30 and 30–50 cm layers ofA. senegalplantations of varying age (ranging from 7 to 24-years-old) and adjacent grasslands (reference) at two sites in semi-arid areas of Sudan. At both sites, three plots were established in each grassland and plantation. The potential ofA. senegalfor N2fixation in relation to plantations age was assessed using δ15N isotopic abundances and nutrient limitations assessed using C:N:P stoichiometry.ResultsSoil concentrations of all studied nutrients were relatively low but were significantly and directly correlated to SOC concentrations. SOC and nutrient concentrations were the highest in the topsoil (0–10 cm) and increased with plantations age. Acacia foliage δ15N values were >6‰ and varied little with plantations age. Soil C:N and C:P ratios did not differ between grassland and plantations and only 0–10 cm layer N:P ratios showed significant differences between grassland and plantations.DiscussionThe results indicated that soil fertility in the Sahel region is strongly related to SOM contents and therefore highlighting the importance of trees in the landscape. The higher mineral nutrient concentrations in the topsoil of the plantations may be an indication of ‘nutrient uplift’ by the deeper roots. The high foliar δ15N values indicated that N2fixation was not an important contributor to soil N contents in the plantations. The accretion of soil N cannot be explained by deposition but may be related to inputs of excreted N brought into the area annually by grazing and browsing animals. The soil C:N:P stoichiometry indicated that the plantations may be limited by P and the grasslands limited by N.
Interlayers Self‐Generated by Additive–Metal Interactions in Organic Electronic Devices

Published: July 2018

AbstractThe fundamental structure of all organic electronic devices is a stack of thin layers sandwiched between electrodes, with precise intralayer morphology and interlayer interactions. Solution processing multilayers with little to no intermixing is, however, technically challenging and often incompatible with continuous roll‐to‐roll, high‐speed manufacturing. Here, an overview of a recently developed methodology for self‐generation of interlayers positioned between the active layer and metal contact is presented. The interlayer material is blended as an additive in the active layer and migrates to the organic/metal interface during metal deposition. The driving force for this migration is additive–metal interactions. The generated interlayer positions an interfacial dipole that reduces barriers for charge transfer across the organic/metal interface. This methodology is generic and, as reported here, the self‐generated interlayers significantly improve the performance of many devices. Importantly, this approach is compatible with printing and reel‐to‐reel processing. Directives toward additive selection, processing conditions and integration in future applications are also discussed.

Published: July 2018

AbstractNoncovalent interactions are the main driving force in the folding of proteins into a 3D functional structure. Motivated by the wish to reveal the mechanisms of the associated self‐assembly processes, scientists are focusing on studying self‐assembly processes of short protein segments (peptides). While this research has led to major advances in the understanding of biological and pathological process, only in recent years has the applicative potential of the resulting self‐assembled peptide assemblies started to be explored. Here, major advances in the development of biomimetic supramolecular peptide assemblies as coatings, gels, and as electroactive materials, are highlighted. The guiding lines for the design of helical peptides, β strand peptides, as well as surface binding monolayer‐forming peptides that can be utilized for a specific function are highlighted. Examples of their applications in diverse immerging applications in, e.g., ecology, biomedicine, and electronics, are described. Taking into account that, in addition to extraordinary design flexibility, these materials are naturally biocompatible and ecologically friendly, and their production is cost effective, the emergence of devices incorporating these biomimetic materials in the market is envisioned in the near future.

Published: July 2018

AbstractHydrogels consist of hydrophilic polymer networks dispersed in water. Many applications of hydrogels rely on their unique combination of solid‐like mechanical behavior and water‐like transport properties. If the temperature is lowered below 0 °C, however, hydrogels freeze and become rigid, brittle, and non‐conductive. Here, a general class of hydrogels that do not freeze at temperatures far below 0 °C, while retaining high stretchability and fracture toughness, is demonstrated. These hydrogels are synthesized by adding a suitable amount of an ionic compound to the hydrogel. The present study focuses on tough polyacrylamide‐alginate double network hydrogels equilibrated with aqueous solutions of calcium chloride. The resulting hydrogels can be cooled to temperatures as low as −57 °C without freezing. In this temperature range, the hydrogels can still be stretched more than four times their initial length and have a fracture toughness of 5000 J m−2. It is anticipated that this new class of hydrogels will prove useful in developing new applications operating under a broad range of environmental and atmospheric conditions.

AbstractWith rapid development for tens of years, organic solar cells (OSCs) have attracted much attention for their potential in practical applications. As an important photovoltaic parameter, the fill factor (FF) of OSCs stands for the effectiveness of charge generation and collection, which significantly depends on the properties of the interlayer and active layer. Here, a facile and effective strategy to improve the FF through hole‐transporting layer (HTL) modification is demonstrated. By mixing WOx nanoparticles with a poly(3,4‐ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) emulsion, the surface free energy of the HTL is improved and the morphology of the active layer is optimized. Benefiting from increased carrier lifetime, a device based on WOx:PEDOT:PSS HTL exhibits a boosted performance with an FF of 80.79% and power conversion efficiency of 14.57% PCE. The results are certified by the National Institute of Metrology (NIM), which, to date, are the highest values in this field with certification. This work offers a simple and viable option of HTL modification to realize highly efficient OSCs.

Published: July 2018

AbstractThe number of older patients admitted to acute hospitals has increased; however, their needs are heterogeneous and there is no gold‐standard method of triaging them towards practicing comprehensive geriatric assessment (CGA). In our hospital, theSAFE(Specialist Advice for the Frail Elderly) team provide an initial geriatric assessment of all emergency admissions of patients aged ≥75 years (with some assessments also occurring in those aged 65 to 74 years) and recommend as to whetherCGAin a dedicated Department of Medicine for the Elderly (DME) ward may be required.SAFEassessments include routine screening for geriatric syndromes using validated tools. Our aim was to compare the characteristics (age, gender, acute illness severity on admission as per modified early warning score (MEWS), Charlson Comorbidity Index, Clinical Frailty Scale (CFS), presence of dementia and delirium) and outcomes (length of stay, delayed discharge, inpatient mortality, discharge to usual place of residence, and new institutionalization) of patients listed to aDMEward, to those not listed. We analyzed allSAFEteam assessments of patients admitted nonelectively between February 2015 and November 2016. Of 6192 admissions, 16% were listed for aDMEward. Those were older, had higherMEWSandCFSscore, were more often affected by cognitive impairment, had longer hospital stay, higher inpatient mortality, and more often required new institutionalization. HigherCFSand presence of dementia and delirium were the strongest predictors ofDMEward recommendation. Routine measurement of markers of geriatric complexity may help maximize access to finite inpatientCGAresources.
