Foram estudadas 73 cepas de S. aureus que apresentaram resistência à oxacilina e/ou cefoxitina na metodologia convencional e automação, isoladas do Hospital Universitário de Santa Maria no ano de 2008. O perfil de sensibilidade frente aos antimicrobianos foi avaliado através da difusão do disco e automação. Para o antimicrobiano vancomicina, foi realizada também a metodologia de microdiluição em caldo. As amostras analisadas apresentaram resistência superior a 75% aos agentes β-lactâmicos, macrolídeos, aminoglicosídeos, lincosamidas e quinolonas e sensibilidade de 73,97% ao sulfametoxazol-trimetoprima. Houve 100% de sensibilidade à linezolida, daptomicina e vancomicina. Na detecção dos MRSA o disco de oxacilina detectou um número maior de cepas resistentes comparado à cefoxitina. A automação teve desempenho equivalente ao disco de oxacilina. A associação de duas metodologias, automação e disco de oxacilina, pode ser uma boa alternativa a ser adotada pelos laboratórios.

Introduction: When comparing oral breathing versus nasal breathing, a greater volume of air can be transported through the oral passageway but nasal breathing may also have benefits at submaximal exercise intensities. Purpose: The purpose of this study was to determine breathing efficiency during increasing levels of submaximal aerobic exercise. Methods: Nineteen individuals (males N=9, females N=10) completed a test for maximal oxygen consumption (VO2max) and on separate days 4-min treadmill runs at increasing submaximal intensities (50%, 65%, and 80% of VO2max) under conditions of oral breathing or nasal breathing. Respiratory (respiration rate [RR], pulmonary ventilation [VE]), metabolic (oxygen consumption [VO2], carbon dioxide production [VCO2]) and efficiency measures (ventilatory equivalents for oxygen [Veq×O2-1] and carbon dioxide [Veq×CO2-1] were obtained. Data were analyzed utilizing a 2 (sex) x 2 (condition) x3 (intensity) repeated measures ANOVA with significance accepted at p≤0.05. Results: Significant interactions existed between breathing mode and intensity such that oral breathing resulted in greater RR, VE, VO2, and VCO2 at all three submaximal intensities (p<.05). Veq×O2-1 and Veq×CO2-1 presented findings that nasal breathing was more efficient than oral breathing during the 65% and 80% VO2max intensities (p<0.05). Conclusion: Based on this analysis, oral breathing provides greater respiratory and metabolic volumes during moderate and moderate-to-high submaximal exercise intensities, but may not translate to greater respiratory efficiency. However when all variables are considered together, it is likely that oral breathing represents the more efficient mode, particularly at higher exercise intensities.

Published: January 2017

Background
Although the relationship between a history of kidney stones and chronic kidney disease (CKD) has been explored in many studies, it is still far from being well understood. Thus, we conducted a meta-analysis of studies comparing rates of CKD in patients with a history of kidney stones.

Methods
PubMed, EMBASE, and the reference lists of relevant articles were searched to identify observational studies related to the topic. A random-effects model was used to combine the study-specific risk estimates. We explored the potential heterogeneity by subgroup analyses and meta-regression analyses.

Results
Seven studies were included in this meta-analysis. Pooled results suggested that a history of kidney stones was associated with an increased adjusted risk estimate for CKD [risk ratio (RR), 1.47 95% confidence interval (CI) [1.23–1.76])], with significant heterogeneity among these studies (I2 = 93.6%, P < 0.001). The observed positive association was observed in most of the subgroup analyses, whereas the association was not significant among studies from Asian countries, the mean age ≥50 years and male patients.

Conclusion
A history of kidney stones is associated with increased risk of CKD. Future investigations are encouraged to reveal the underlying mechanisms in the connection between kidney stones and CKD, which may point the way to more effective preventive and therapeutic measures.

Abstract2D materials have been interested in recent years due to their unique properties and enormous potential in various fields. In particular, 2D ferroionics with both ferroelectricity and ionic conductivity shed light on new possibilities for van der Waals nanoelectronics. Here, supported by theoretical calculations and electrical characterizations, the reconfigurable van der Waals ferroionic barristor that can be used in multifunctional electronics including resistive devices and steep‐slope transistors is reported. Large modulation on the device properties is achieved by electrically driven migration and redistribution of mobile ions. The memory device shows an unprecedented long‐term stability with a switching ratio of ≈1010. Utilizing this ferroionic nature, 2D transistors able to beat the Boltzmann tyranny, with different gate configurations, are designed. The subthreshold swing (SS) exhibits sub‐60 mV per decade values over five decades of the drain current with a minimum of 12.1 mV per decade. This work paves the way for investigating the symbiotic relationship of ferroelectricity and ionic activities in van der Waals ferroionics and highlights their applications in advanced nanoelectronics.

AbstractAdsorption is a classical physicochemical process, widely used in heterogeneous catalysis, chemical engineering, and environmental science. Regenerating the exhausted adsorbents or reversible desorption is vital to achieving sustainable adsorption techniques, while the common chemical/thermal regeneration is energy‐intensive and environmentally unfriendly. Given that the adsorbents’ surface physicochemical properties like surface charge and electronic structures, significantly affect adsorption capacity and kinetics, which offers opportunities for green desorption by tailoring surface chemical/electronic features. Since a certain adsorbate possesses specific adsorption energy on adsorbents, an electro‐desorption idea is therefore proposed to electrically control the (sequential) release of aqueous substances by regulating the interfacial adsorption interaction above the corresponding threshold interfacial potential. Herein, as a proof‐of‐concept design, a sub‐millimeter‐sized carbon nanotube‐reinforced conductive resin composite adsorbent with high conductivity and mechanical strength is developed, which demonstrates a high electro‐desorption efficiency toward benzoic acid (94.1%; 3 V negative bias) and well‐controlled electro‐desorption kinetics by regulating the surface polarization. Using benzoic acid and terephthalic acid as a model of organic mixtures, the adsorbent exhibits an efficient bias‐dependent sequential electro‐desorption capability in separating mixtures. This work provides a promising efficient solution for green and efficient desorption/regeneration and a pioneering electrically‐driven strategy toward aqueous mixture separation.
Foam‐to‐Foam Recycling Potential of PU‐Foams by Integration of Amino Esters

Published: September 2024

AbstractThe increasing market demand for flexible polyurethane foams (PUFs) is prompting the academic and industrial community to seek solutions for their end‐of‐life management. In this study, this issue is addressed by incorporating β‐amino ester (BAE) moieties into the foam structure. This addition results in flexible hybrid PU‐BAE foams that can be thermally reprocessed and chemically recycled, with cell sizes ranging from 780 to 990 µm and densities between 90 and 150 kg m−3. These foams demonstrate thermomechanical reprocessability, yielding stable PU‐BAE elastomers, with glass transition temperature values ranging from 14 to 25 °C. Stress relaxation experiments reveal remarkably fast relaxation times for these hybrid elastomers (23 s at 160 °C). Furthermore, a systematic investigation of the chemical recyclability of these foams via glycosylation is conducted under mild conditions, achieving complete disintegration within 20 min at 65 °C. Finally, the chemically recycled product is converted into a foam again, achieving a closed loop foam‐to‐foam recycling process. These findings indicate that the integration of BAE into PUFs leads to an enhanced chemical recycling rate, providing a promising avenue for addressing end‐of‐life concerns in PUF‐applications.

AbstractTriple‐cation mixed‐halide (TCMH), i.e., (FAPbI3)1‐x‐y(MAPbBr3)y(CsPbI3)x, perovskite single‐crystal thin‐films (SCTFs) have emerged as candidates for high‐performance photodetectors. However, high lattice strain, surface defects, and the non‐ideal yellow phase such as δ‐FAPbI3 and δ‐CsPbI3, are impeding the realization of high‐quality TCMH SCTFs. Therefore, the synthesis of pure‐phase, high‐quality TCMH SCTFs with low lattice strain and defect density is imperative for enhancing light absorption and carrier mobility, thereby optimizing photoresponsivity. Herein, an innovative approach is proposed for synthesize TCMH SCTFs using an optimized space‐limited anti‐solvent assisted crystallization technique which employs 2‐methoxyethanol as the solvent and diethyl ether as anti‐solvent, devoid of thermal enhancement. A novel reducing additive, formic acid, is incorporated to mitigate phase separation, and the composition ratio is meticulously adjusted to regulate lattice strain. The results show that a pure‐phased optimal composition ratio (FA0.82MA0.11Cs0.07) SCTF with a low surface defect density (2.29 × 109 cm−2), low lattice strain (0.81%) and high hole mobility (77.58 cm−2 V−1 s−1) is successfully prepared. Moreover, the non‐integrated planar FA0.82MA0.11Cs0.07 SCTF photodetector also achieved a record photo‐responsivity (229.5 A W−1), and external quantum efficiency (5.4 × 104%), indicating its great potential in light‐detecting. This research paves the way for the development of high‐performance photodetectors via adjusting lattice strain and mitigating surface defects in TCMH SCTFs.

AbstractSuper macroporous (SMP) hydrogels have garnered significant attention in biomedical applications due to their high permeability and biomimetic pore structure. However, maintaining toughness in highly porous materials remains a formidable challenge. This study introduces a facile one‐step preparation method for fabricating tough alginate hydrogels with an SMP structure by blending polyvinyl alcohol (PVA) and sodium alginate cross‐linked with calcium chloride. By capitalizing on the phase separation effect, this method bypasses traditional requirements such as cryogelation and templating that necessitate low temperatures or solvent etching. The presence of PVA molecules promotes the regional aggregation of alginates, leading to enhanced toughness, and also occupies larger interstitial spaces between the densely packed alginate phases, facilitating pore formation. The resulting SMP structure, featuring pore sizes ranging from 50 µm to 700 µm, forms during the polymer cross‐linking process and achieves a porosity exceeding 85%. These hydrogels exhibit superior toughness compare to their non‐macroporous counterparts. Additionally, this method allows for flexible adjustments in the porous structure and overall gel shape, making it adaptable to various applications. This simple yet effective approach holds great potential for developing novel SMP materials with enhanced toughness.
