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.

IntroductionObstructive sleep apnea syndrome affects up to 4% of middle-aged men and 2% of adult women. It is associated with obesity. ObjectiveThe objective of this article is to review the literature to determine which factors best correlate with treatment success in patients with obstructive sleep apnea syndrome treated with a mandibular repositioning appliance. Data SynthesisA search was performed of the PubMed, Cochrane, Lilacs, Scielo, and Web of Science databases of articles published from January 1988 to January 2012. Two review authors independently collected data and assessed trial quality. Sixty-nine articles were selected from PubMed and 1 from Cochrane library. Of these, 42 were excluded based on the title and abstract, and 27 were retrieved for complete reading. A total of 13 articles and 1 systematic review were considered eligible for further review and inclusion in this study: 6 studies evaluated anthropomorphic and physiologic factors, 3 articles addressed cephalometric and anatomic factors, and 4 studies evaluated variables related to mandibular repositioning appliance design and activation. All the studies evaluated had low to moderate methodologic quality and were not able to support evidence on prediction of treatment success. ConclusionBased on this systematic review on obstructive sleep apnea syndrome treatment, it remains unclear which predictive factors can be used with confidence to select patients suitable for treatment with a mandibular repositioning appliance.

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.

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.

No tillage implies keeping the soil surface covered with crops or crop residues, which might influence planter performance. Using fixed shanks as furrow openers to place fertiliser is an alternative to minimize compaction, as it mobilizes the soil in the sowing line. The aim of this research was to evaluate the effect of different amounts of winter cover crop residues evenly distributed on the soil, the effect of the shanks working depth and quantity of planter lines on power demand, cross sectional furrow area and total volume of soil mobilized in the lines and corresponding wheel slippage in distrophic red Argisol. During winter, black oats and black oats plus turnip were used as cover crops before maize and beans, respectively. Increasing the working depth showed an increase in power demand, as measured directly at the shanks (three lines for maize and five for beans). There was also an effect of residue, increasing power demand on the shanks, but only measurable with the planter operating with three lines in maize sowing. Soil mobilization in the sowing lines was influenced by the amount of residues, the working depths of shank and the quantity of planter lines. Wheel slippage was higher with larger amounts of soil cover residues and when power demand was higher.

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.

Objective: To evaluate the effects of aquatic physical therapy on pain and on the cycle of sleep and wakefulness among stable hospitalized premature infants. Method: This study was characterized as an uncontrolled clinical trial on a time series and included 12 clinically stable newborns of gestational age less than 36 weeks who were hospitalized in a neonatal intensive care unit (NICU). After selection, the newborns were placed in a liquid medium for aquatic physical therapy lasting 10 minutes. Movements to stimulate flexor posture and postural organization were performed. The sleep-wakefulness cycle was assessed using the adapted Brazelton (1973)* scale and pain was assessed by the occurrence of signs of pain according to the Neonatal Facial Coding System (NFCS) scale; and physiological parameters. Results: In relation to states of sleep and wakefulness, before the physical therapy, the newborns' behavior varied from fully awake with vigorous body movements to crying. After the physical therapy, the states of sleep ranged from light sleep with closed eyes to some body movement. These values presented statistically significant differences (p<0.001). The score on the pain assessment scale also decreased from 5.38±0.91 to 0.25±0.46, with p < 0.001 after the intervention. The vital signs remained stable. Conclusion: It is suggested that aquatic physical therapy can be a simple and effective method for reducing pain and improving sleep quality among preterm infants in NICUs. Controlled studies with larger numbers of subjects are needed in order to generalize the results. © Revista Brasileira de Fisioterapia.

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.

This article presents a new class of hybrid converters named Switched-Linear (SL) Converters that can operate as a DC-DC, DC-AC or AC-DC converter. The idea is originated from conventional linear power amplifier integrated with a switched power converter. The linear power unit/cell is a power amplifier, which is fed by two tracking power supplies to boost the efficiency of the linear unit without scarifying any virtues of linear power amplifier. It can be achieved making the voltage in the linear amplifier the lowest possible level and adequate to application. The main goal is to guarantee the possibility of drain reversal power energy whenever it processes reversal power flux and/or non-resistive loads. Therefore, by combining the linear power amplifier with the switched power amplifier, the system has synthetic performance of high fidelity, high efficiency and excellent dynamic characteristics. © 2015 IEEE.

The aim is to present a rare case of ligamentum flavum hematoma in the lumbar region, discuss its physiopathology and treatment and review the literature. A woman aged 68 presented with neurogenic claudication due to degenerative lumbar spondylolisthesis that evolved into a sudden worsening with cauda equina syndrome. The magnetic resonance imagining (MRI) showed signs of degeneration of the lumbar spine, with a narrow spinal canal from L2 to S1, anterolisthesis L4 L5 and an expansive lesion hyperintense on T1-weighted and hypointense on T2-weighted images considered compatible with hematoma in the topography of the yellow ligament in L1-L2. The patient underwent laminectomy and lumbar fixation. Her evolution was good in the postoperative period and at 18 months of follow-up hse walked alone, despite the pain that is controlled with simple medications. Even though rare, it seems that ligamentum flavum hematoma has a relationship with the degeneration and rupture of small vessels associated with micro trauma to the spine. Its physiopathology is not well defined and treatment is similar to other spine compression processes.
