Background: Recently, late umbilical cord clamping is generally recommended, which decreases neonatal anemia;however, it may also increase neonatal jaundice and some other poor outcomes. Objectives: We here attempted to determine whether late clamping actually increases the incidence of phototherapy for jaundice and other poor outcomes of the term “low-risk newborns”. Methods: With the approval of the Brazilian Registry of Clinical Trials (REBEC), a total of 357 low-risk newborns (singleton, uncomplicated pregnancy/delivery, in a Brazilian public institution) were randomized into two groups: group I (n = 114): cord clamping 1 minute (early clamping) or group II (n = 243): cord clamping between 1 - 3 minutes (late clamping). Statistics were used appropriately (i.e., measures of central tendency, dispersion for continuous variables, Shapiro-Wilk, Mann-Whitney test, or Chi-square test). Results: Phototherapy was performed in 5.3% in both groups. Also, there were no statistical differences in the occurrence of secondary outcomes, such as sepsis, neonatal ICU admission, and transient tachypnea of the newborns: i.e., 0.9%, 15.8%, and 3.5%, respectively for group I versus 1.2%, 15.6%, and 5.8%, respectively for group II. Conclusion: Late umbilical cord clamping does not increase the need for phototherapy in low-risk neonates. This result corroborates the current recommendation of late cord clamping, whenever appropriate.

Recent monitoring techniques employ multiple sources of information for the characterization of the phenomenon to be studied, being the coupling and adjustment of multi-source data one of the first challenges to consider and solve. The authors propose a new framework of the multi-source and multi-temporal data-oriented fusion for the characterization of landslide events. The main objective is to generate 3D virtual models(in the form of dense point clouds) and feed them back with the characteristic of soil and subsoil information. The scheme consists of three main steps. The first one is on-site data collection(geological characterization, geophysical measurements, GPS measurements, and UAV/drone mapping). The second step is generation of a high-resolution 3D virtual model(~1-inch spatial resolution) from the frames acquired through the UAV using the structure of motion(SfM) processing;the developed virtual model is optimized with GPS measurements to minimize geolocation error and eliminate distortions. The last step is assembling of the acquired data in the field and densified point cloud considering the different nature of the data, re-escalating procedure and the information stacking layer.

This study was conducted to identify the origin, hydrogeochemical processes and evolution of groundwater in a tectonic valley. This study was carried out with the aim of quantifying the proportions of groundwater flows contributing to the water chemistry abstracted in a zone of convergence favored by the presence of active faults. The study area is located in the Trans-Mexican Volcanic Belt. End members methodology was applied to identify the mixing of hydrothermal with fresh groundwater, where changes in the aquifer geology result in distinct groundwater chemical signatures. Ternary mixing was quantified using conservative elements. Moreover, other evolutionary processes, such as ion exchange and silicate weathering occur due to changes in the geology of the area. In ternary mixing, each of the end members is associated with the lithology through which it circulates. The local flow contributes 70% of the water to the system, the intermediate flow contributes 14%, and the regional flow contributes 16%. Three types of water are produced: Na-HCO3, due to the interaction of water with volcanic rocks of rhyolitic composition, Na-Mg-HCO3, due to the interaction of water with volcanic rocks of basaltic-andesite composition, and Ca-HCO3, due to the interaction of water with sedimentary calcareous rocks.

Type 2 diabetes （T2D） is an important risk factor for developing dementias, including Alzheimer＇s disease （AD）. Hyperinsulin- emia and glucose intolerance, as features of T2D, might increase the neurodegeneration process, synaptic loss and brain atrophy, leading to cognitive impairment observed in AD. Also, adult neurogenesis seems to be impaired in AD models. Therefore, we have studied morphological alterations, cell proliferation and neurogenesis in the central nervous system （CNS） from a classical model of T2D, the db/db mouse, and in a prediabetes insulin-resistant model, obtained after long-term high fat diet （HFD） administration to C57B1/6 mice. Db/db mice showed an age-dependent cortical and hippocampal atrophy, whereas in HFD mice cortex and hippocampus were preserved. Neurogen- esis and cell proliferation were increased in young db/db mice, when compared with control mice, whereas no differences were detected in the prediabetic model. We also detected significant correlations between metabolic parameters and central atrophy, altered proliferation and neurogenesis in the central nervous system. Altogether these data support that glycaemia control in elderly patients, could help to control central alterations and improve dementia prognosis.

Power line inspection is an essential procedure in the power lines maintenance area, especially thinking about service availability and energy efficiency. Aerial inspection of electric power transmission lines is typically performed using human-piloted helicopters, which is a procedure that is both expensive and prone to accidents taking risks to human beings＇ lives. The work presents a solution based on UAS （unmanned aircraft system） for inspecting power lines. In this context a R ＆ D project of an unmanned aircraft system to be used for performing complete aerial inspection of overhead power lines is being executed by ITA （Instituto Tecnol6gico de Aeron^utica）（Technological Institute of Aeronautics） in Brazil. Special attention is dedicated to the communication system conception in order to comply with Remotely Piloted Aircraft System definition in the context of long endurance operations of the system. It presents a solution based on LTA （lighter than air） platform in order to extend the communication range beyond line of sight.

Introduction: Urinary incontinence is a common problem that can affect the quality of life of women of all ages and can negatively influence the exercise of sexuality. Aim: The aim of this study was to compare sexual function of women before and after surgical treatment for urinary incontinence. Method: The sample consisted of 38 women with urinary incontinence and surgical treatment (Burch or Sling procedure). The Female Sexual Function Index (FSFI) was used to evaluate sexual dysfunction before and after surgical treatment. Results: The mean age of the women in the study was 48 ± 8.8 years, and 58% were 50 years old or younger. By analyzing FSFI, it was observed that the majority of subjects had an overall index of sexual dysfunction (score < 26 points) before surgery. The desire and arousal domains improved significantly after surgery for all women included in the study. It was also observed that women with higher levels of education had more positive results related to desire. Conclusions: In our sample, in general, sexual function improved after surgical treatment of urinary incontinence, regardless of technique used, particularly in the discounter and pain domain. There was a substantial improvement of the sexual function among women who had presented with cystocele. Desire and arousal improved significantly after surgery, very likely due to the improvement of self-esteem after surgery.

OBJECTIVE: To compare maternal preoperative and postoperative hemoglobin variation after cord clamping. METHODS: Randomized clinical trial performed in Porto Alegre, RS from January to December 2012. It was included 356 women with habitual risk gestations. In the immediate cord clamping group, the umbilical cord section was realized between 0 and 60 s (group 1) while in the delayed cord clamping group it was realized >60 s (group 2). RESULTS: The mean (±standard deviation [SD]) preoperative hemoglobin was 12.13 ± 1.06 in the group 1 and 12.13 ± 1.11 in the group 2. The mean (±SD) postoperative day 2 hemoglobin level was 10.19 ± 1.46 in the group 1 and 10.24 ± 1.42 in the group 2. CONCLUSIONS: Delayed umbilical cord clamping resulted in a similar maternal hemoglobin level reduction at postoperative day 2.

This paper presents an overview and analyzes the impact of the Partido Renacimientoy Union de Espana （PRUNE, Renascence Party and Union in Spain） specifying in the socio-political articulation of Muslims in Spain. In particular, it aims to describe and analyze the historical and political context of the emergence of these types of parties in the European Union （EU）; their background in Spain, particularly in the Autonomous Cities of Ceuta and Melilla and their specific impact on socio-political movements. The main hypotheses of work are the heterogeneity of Islamic communities in Spain, its religious references and social integration are difficult and complex, implying that this will provide a strategic impact from PRUNE, which could be very limited, slow, and uncertain.
