    Abstract Objective: The Brazilian Consensus on Hip Viscosupplementation aims to generate a referential and consensual source from the theoretical knowledge and clinical experience of specialists in the field.
    Methods: A multidisciplinary panel was formed with 15 specialists (sports medicine, orthopedists, physiatrists and rheumatologists), based on clinical and academic experience in the use of viscosupplementation of the hip. 12 statements were prepared, discussed and voted. Each panelist gave a value between 0 and 10 on a Likert scale, specifying their level of agreement with the statement.
    Results: The panel reached a consensus on several aspects of viscosupplementation of the hip, with emphasis on the following statements: best indication is for mild to moderate hip arthrosis; it may be indicated in severe osteoarthritis; results may vary according to the characteristics of the viscosupplement used; Viscosupplementation should not be performed as an isolated procedure, but in conjunction with other rehabilitation and pharmacological measures; best injection technique should be based on anatomical references coupled with imaging guidance; it is a cost-effective procedure.
    Conclusion: Viscosupplementation is a safe and effective therapy for hip osteoarthritis, even in severe cases. Guided injection is recommended.

    Abstract When it comes to the sensory analysis of specialty coffees, it is necessary to discuss the protocol of tests of the Specialty Coffee Association (SCA) and the formation of Q-Graders as reliable parameters in the sensory analysis. However, the training of these Q-Graders and the use of the SCA protocol has generated discussions in the scientific community and demonstrated the importance of talking about the level of professional precision as well as the use of the protocol. This study sought to understand the relation of accuracy and efficiency of the Q-Graders and protocol in the sensory analysis of coffees. Three experiments were carried out to evaluate and test the hypotheses regarding the level of precision in relation to the shift, the number of samples and the judgment abilities of Q-Graders due to the quality of the specialty coffee and nonspecialty coffee. These three experiments were performed by seven Q-Graders in an isolated environment during three consecutive days with 137 specialty coffee samples and 7 nonspecialty coffee samples as defined by the SCA. The results indicate that the Q-Graders present high precision when evaluating excellent and outstanding coffees, as defined by the SCA. In addition, the effect of the shift did not exert fatigue on the Q-Graders. However, evaluation errors were made by the Q-Graders on very good coffee (77.00-80.00 points), which are considered as nonspecialty by the SCA, thus allowing a more in-depth discussion on what would be the boundary between a specialty and nonspecialty coffee. PRACTICAL APPLICATIONS: The article deals with the sensory evaluation process of coffees, and it has great importance to teaching and research institutions in Brazil, the largest producer, largest exporter and the country with the highest concentration of coffee scholars in the world. The article focuses on a new approach and a new way of looking at the sensory evaluation process of coffees, using the methodology of the Specialty Coffee Association to analyze the accuracy and efficiency of the Q-Graders.

    Abstract The FACE-Q SFAOS is an instrument developed for esthetic facial procedures and has been validated in patients undergoing rhinoplasty. It consists of ten items that assess the current perception of facial appearance regarding symmetry, harmony, proportion, freshness or vitality, and self-perception of appearance; these items are perhaps important to guide demands in orofacial harmonization (OFH). We aimed to validate the FACE-Q SFAOS scale among professionals working with OFH and verify its acceptance for use in clinical practice. Altogether, 25 OFH specialists were included to evaluate the FACE-Q SFAOS scale and the new technology acceptability model (TAM). Internal validity was measured using Cronbach's α coefficient. Both scales were associated with clinical experience and perceived usefulness using Spearman's correlation and Fisher's exact or chi-square tests (SPSS 20.0, p < 0.05). The FACE-Q SFAOS (α = 0.927) and TAM (α = 0.941) scales demonstrated good internal validity, and most professionals demonstrated good acceptance (TAM >70 = 64%). The mean FACE-Q SFAOS and TAM scores were 64.00±17.03 and 74.60±20.66, respectively. Practitioners with more than two years of experience (p=0.032) who believed the scale was useful for lip filler evaluation (p = 0.017) demonstrated greater acceptance. The number of indications on the scale was directly correlated with higher levels of acceptance (p = 0.002, r = 0.594). Thus, the FACE-Q SFAOS scale has good reproducibility and acceptance among OFH specialists; however, acceptability was shown to be dependent on perceived usability.

  5. Book ; Online: Generating Scientific Question Answering Corpora from Q&A forums

    Abstract: ... sets. We present a method to automatically extract question-article pairs from Q&A web forums ...

    Abstract Question Answering (QA) is a natural language processing task that aims at retrieving relevant answers to user questions. While much progress has been made in this area, biomedical questions are still a challenge to most QA approaches, due to the complexity of the domain and limited availability of training sets. We present a method to automatically extract question-article pairs from Q&A web forums, which can be used for document retrieval and QA tasks. The proposed framework extracts questions from selected forums as well as answers that contain citations that can be mapped to a unique entry of a digital library. This way, QA systems based on document retrieval can be developed and evaluated using the question-article pairs annotated by users of these forums. We generated the SciQA corpus by applying our framework to three forums, obtaining 5,432 questions and 10,208 question-article pairs. We evaluated how the number of articles associated with each question and the number of votes on each answer affects the performance of baseline document retrieval approaches. Also, we trained a state-of-the-art deep learning model that obtained higher scores in most test batches than a model trained only on a dataset manually annotated by experts. The framework described in this paper can be used to update the SciQA corpus from the same forums as new posts are made, and from other forums that support their answers with documents.

    Abstract This work explores interference coordination techniques (inter-cell interference coordination, ICIC) based on fractional frequency reuse (FFR) as a solution for a multi-cellular scenario with user concentration varying over time. Initially, we present the problem of high user concentration along with their consequences. Next, the use of multiple-input multiple-output (MIMO) and small cells are discussed as classic solutions to the problem, leading to the introduction of fractional frequency reuse and existing ICIC techniques that use FFR. An exploratory analysis is presented in order to demonstrate the effectiveness of ICIC techniques in reducing co-channel interference, as well as to compare different techniques. A statistical study was conducted using one of the techniques from the first analysis in order to identify which of its parameters are relevant to the system performance. Additionally, another study is presented to highlight the impact of high user concentration in the proposed scenario. Because of the dynamic aspect of the system, this work proposes a solution based on machine learning. It consists of changing the ICIC parameters automatically to maintain the best possible signal-to-interference-plus-noise ratio (SINR) in a scenario with hotspots appearing over time. All investigations are based on ns-3 simulator prototyping. The results show that the proposed Q-Learning algorithm increases the average SINR from all users and hotspot users when compared with a scenario without Q-Learning. The SINR from hotspot users is increased by 11.2% in the worst case scenario and by 180% in the best case.

    Abstract This paper studies the trajectory optimization problem for an aerial vehicle with the mission of flying between a pair of given initial and final locations. The objective is to minimize the travel time of the aerial vehicle ensuring that the communication connectivity constraint required for the safe operation of the aerial vehicle is satisfied. We consider two different criteria for the connectivity constraint of the aerial vehicle which leads to two different scenarios. In the first scenario, we assume that the maximum continuous time duration that the aerial vehicle is out of the coverage of the ground base stations (GBSs) is limited to a given threshold. In the second scenario, however, we assume that the total time periods that the aerial vehicle is not covered by the GBSs is restricted. Based on these two constraints, we formulate two trajectory optimization problems. To solve these non-convex problems, we use an approach based on the double Q-learning method which is a model-free reinforcement learning technique and unlike the existing algorithms does not need perfect knowledge of the environment. Moreover, in contrast to the well-known Q-learning technique, our double Q-learning algorithm does not suffer from the over-estimation issue. Simulation results show that although our algorithm does not require prior information of the environment, it works well and shows near optimal performance.

    Abstract Sibutramine is cited by the World Anti-Doping Agency as a stimulant. According to the literature, sibutramine is extensively metabolized into N-desmethyl-sibutramine (M1), N-bisdesmethyl-sibutramine (M2) and monohydroxy derivatives of M1 and M2. Therefore, it is important to verify new sibutramine metabolites through current analytical methodologies, such as liquid chromatography coupled to high resolution mass spectrometry (LC-HRMS). Furthermore, the development of a comprehensive approach to investigate sibutramine metabolism can increase the detection window for stimulant misuse and enable advancements in pharmacological studies. This work aimed to develop and evaluate the performance of an LC-HRMS method applying Design of Experiments (DoE) for sibutramine metabolite analysis in human urine. After optimizing the method by DoE, the final chromatographic conditions were based on reversed-phase chromatography using a C18 column with a ramp time of 25 min, a flow rate of 0.17 mL min

    Abstract A complete characterization of yacon syrup was performed by analytical techniques, including NMR and UPLC-QTOF-MSE. The effect of the different stages of yacon syrup production on fructooligosaccharides (FOS) and chlorogenic acid (CGA) contents were also evaluated. As a result, in addition to higher levels of FOS and CGA, some mineral elements, such as K, Ca and P, and essential amino acids, such as tryptophan, valine, and threonine, were determined in yacon syrup. Twenty-five compounds were putatively identified, and the main compounds were phenolics derived from quinic and trans-cinnamic acids. Considering the different stages of yacon syrup production, the results indicate that the contents of FOS and CGA were maintained in the pulping, enzymatic maceration and microfiltration, leading to a concentration of these components in the last stage of processing (vacuum concentration). These results will be used to fortify this innovative and promising product in the area of functional foods.
