Introduction: The treatment and recovery of a pediatric inpatient may take a long time. During the child's stay in the hospital environment, it is not uncommon to observe the development of emotional crises affecting both child and mother. Objective: To assess the prevalence of depression and anxiety symptoms among mothers who had their children admitted to the pediatric ward of a university hospital in southern Brazil. Methods: This was a cross-sectional study in which the Beck Anxiety and Depression Inventories (BAI and BDI, respectively) were dministered to 140 women between 31 and 365 days postpartum. The cut-off point of > 20 on BAI and BDI was used to defi ne the presence of anxiety and depression. Results: Of the 140 women assessed, 43 (30.7%) presented BDI scores > 20, and were therefore considered to be depressed; 46 (32.9%) showed BAI scores > 20, and were considered to be anxious; 26 women (18.6%) presented both depression and anxiety. Women living under more vulnerable social conditions more frequently presented both depression and anxiety, namely younger women, those with lower education levels and lower income, those who did not have private health insurance and women who had more children. Conclusion: The preventive action of multidisciplinary teams in the fi rst months postpartum is necessary due to the high frequency of depression and anxiety symptoms among mothers of pediatric inpatients. Such action will allow mothers who are present at the hospital to be referred to appropriate mental health professionals. © Revista de Psiquiatria do Rio Grande do Sul - APRS.

Planar motion over a surface is commonly acquired using a combination of rotatory motors and appropriate mechanical transmissions to convert the torque produced by the motor into linear motion. Typically, the assembly employs two motors: one is responsible for the motion in the x-axis and the other, for the y-axis [1]. A planar actuator achieves this kind of motion from only one device. Several different types of planar actuator have been studied. These have utilized different types of actuator, such as switched reluctance actuators [2], permanent magnet DC devices [3, 4, 5], and AC actuators [1, 6]. There are various possible applications for planar motion devices. There have been identified as being in the semiconductor industry (for wafer probers [2], extreme-UV lithography equipment [3], printed circuit board movers [4, 5], and scanning microscopy [5]) and for mobile robots [6]. Another proposed application is to use the characteristics of this new actuator for the inspection of inclined surfaces, such as ship hulls and oil tanks. Based on the adhesive nature of these devices, they can be classified into magnetic, vacuum or suction, grasping grippers, electrostatic and biologically inspired robots [7]. © 2015 IEEE.

The purpose of this research was to ascertain the population's knowledge about oral cancer and propose permanent actions incorporated to the Primordial Prevention Measures. Materials and Methods: There were apply questionnaires in 120 patients of a Basic Health Unit, and most the sample were female and the aged was between 18-82 years. Results: The results showed that most of users don’t know adequately about the oral cancer, of which, some believe it’s a communicable disease, others believe it’s not even a disease. Users know some of the risk factors, but they don’t know how to perform self-examination of the mouth. Conclusions: It is suggested the incorporation of three new actions to Prevention Primordial Measure, including the creation of a permanent program in Elementary and Secondary Education Schools, encouraging in favor of self-examination of the mouth and against the use of tobacco and alcohol; the training of dentists from the public care about the actions of measures in Primary and Secondary Prevention; and the integration of effective communication about the actions of measures in Primary and Secondary Prevention. © 2016, Universidade Federal de Uberlandia.

The presence of pharmaceuticals in aqueous environmental matrices often requires efficient and selective preconcentration procedures. Thus, silicas (SILs) were synthesized by a molecular imprinting technique using an acid-catalyzed sol-gel process and the following drugs as templates: fluoxetine, gentamicin, lidocaine, morphine, nifedipine, paracetamol, and tetracycline. The materials were subjected to sorbent extraction assisted by ultrasonic treatment to remove the drugs and the consequent formation of molecular imprinted cavities. The surface area of the resulting materials ranged from 290 to 960 m2/g. Adsorption tests were performed with the molecular imprinting phases. In terms of the potential selectivity, the SILs were subjected to the adsorption of drugs from samples such as potable and surface water. The adsorption capacity remained in the range between 55 and 65% for both matrices, while for the nonimprinted SIL it remained between 15 and 20%. © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

We assessed the abilities of rice husk (RH), rice husk carbon (RHC), and peat to adsorb Cr, Fe, Mn, Ni, Zn, and Pb from aqueous solutions compared with commercial activated carbon (AC). The sorbent capacities were evaluated by percolation of aqueous solutions containing these six metals through adsorbent columns. Metal concentration was monitored by total reflection X-ray fluorescence (TXRF). Initial metal concentrations added to the columns were between 25 and 50 mg L-1, while those in the treated effluent ranged from 0.004 to 0.96 mg L-1. The adsorption capacities of the sorbents for these metals were examined by non-linear Langmuir and Freundlich models. The maximum adsorptive capacities expressed as individual metal (q m) sums were 67.7, 86.9, 80, and 44.6 mg g-1 for AC, RHC, peat, and RH, respectively. The resulting isotherm parameters were used to compare the performance of the sorbents and to determine the ΔG values. After percolation through the adsorbent columns, the ecotoxicity of the eluates were determined with the probe Daphnia magna. Effluents from the rice husk sorbent column exhibited the lowest toxicity. Supplemental materials are available for this article.
