Background: There is a dearth of knowledge regarding the correlation between femoroacetabular impingement (FAI) and osteitis pubis (OP) among symptomatic soccer players. Purpose: To elucidate whether arthroscopic FAI correction is effective for young competitive soccer players with FAI combined with OP or perisymphyseal pubic bone marrow edema (BME). Study Design: Case series; Level of evidence, 4. Methods: A total of 577 consecutive patients who underwent arthroscopic FAI correction were retrospectively reviewed with a minimum 2-year follow-up. Competitive soccer players who were professional, college, and high school athletes were included. The authors assessed the modified Harris Hip Score and Nonarthritic Hip Score preoperatively and at 6 months, 1 year, and 2 years after surgery. In addition, players were divided into groups according to radiographic evidence of OP and BME (2 groups each). Clinical outcomes, return to play, and radiographic assessments were compared between groups. Results: Twenty-eight hips met the inclusion criteria. The median modified Harris Hip Score significantly improved after hip arthroscopy (81.4, preoperatively; 95.7 at 6 months, P = .0065; 100 at 1 year, P = .0098; 100 at 2 years, P = .013). The median Nonarthritic Hip Score also significantly improved (75.0, preoperatively; 96.3 at 6 months, P = .015; 98.8 at 1 year, P = .0029; 100 at 2 years, P = .015). Furthermore, 92.0% of players returned to play soccer at the same or higher level of competition at a median 5.5 months (range, 4-15 months); 67.8% had radiological confirmation of OP; and 35.7% had pubic BME. The alpha angle was significantly higher in pubic BME group than the no–pubic BME group (64.8° vs 59.2°, P = .027), although there was no significant difference between the OP and no-OP groups. The prevalence of tenderness of the pubic symphysis significantly decreased preoperatively (32.1%) to postoperatively (3.6%). Magnetic resonance imaging findings confirmed that pubic BME disappeared in all players at a median 11 months (range, 6-36) after initial surgery. Conclusions: Arthroscopic management for FAI provides favorable clinical outcomes, a high rate of return to sports, and, when present, resolution of pubic BME among competitive soccer players.
Feline chronic gingivostomatitis is more prevalent in shared households and its risk correlates with the number of cohabiting cats
Authors: Peralta Santiago , Carney Patrick C 
Published: January 2019

Objectives The aim of this study was to determine whether feline chronic gingivostomatitis (FCGS) is more prevalent in shared vs single-cat households, whether the number of cohabiting cats or outdoor access represent risk factors for FCGS and whether the number of cohabiting cats is a useful prognostic indicator for standard surgical treatment. Methods Cats diagnosed with FCGS (study group) in the past 5 years at a referral institution were identified. The number of cohabiting cats, outdoor access, number of other cohabiting cats diagnosed with FCGS, ⩾6 month surgical outcome, when applicable, and historical signs of upper respiratory disease among any of the cohabiting cats, as well as patient demographic information, were recorded. Data were collected from medical records and by means of a telephone interview with the owners. The same information was collected from a group of cats of similar demographic characteristics diagnosed with periodontal disease but free of FCGS (control group). Results Seventy-six cats were included, of which 36 (47%) had FCGS and 40 (53%) served as controls. Bivariate analysis showed that cats with FCGS were significantly more likely to come from shared households, and had significantly more total cats per household compared with controls. Multivariate analysis also showed that cats in shared households had a significantly increased odds of FCGS compared with those from single-cat households. Historical signs of upper respiratory disease and outdoor access among cats within the same household were not associated with FCGS. The number of cohabiting cats was not associated with surgical outcome. Conclusions and relevance Cats with FCGS are more likely to live in shared households. The risk of FCGS correlates with the number of cohabiting cats. The epidemiological features of FCGS may support an infectious etiology. The number of cohabiting cats within a household is not a useful prognostic indicator for standard surgical treatment of FCGS.

Published: January 2019

Background: The incidence of mortality five years after the onset of symptomatic heart failure is about 50%. Lifestyle behaviors differ substantially and likely lead to prognostic differences. Aims: We sought to determine the factors associated with all-cause mortality in patients with heart failure, particularly the impact of a sedentary lifestyle on mortality. Methods: This is a secondary analysis of a randomized controlled trial (REMOTE-HF) to improve self-care through education and counseling ( N=602). We conducted an unadjusted Cox proportional hazards regression analysis with sedentary lifestyle as a predictor of mortality, then added depressive symptoms as a confounder. A Kaplan–Meier survival analysis assessed time to event comparing sedentary lifestyle. Cox models included variables of clinical relevance as well as all significant variables from baseline characteristics associated with all-cause mortality. Results: The mean ± SD age was 66 ± 12.4 years, 41% were women, and 90% were of white race. There were 125 all-cause deaths over 24 months. Sedentary lifestyle was associated with a 75% increase in the expected hazard of all-cause mortality (hazards ratio 1.75; p = 0.003; 95% CI 1.21–2.54) after adjusting for moderate to severe depressive symptoms. Two Cox models showed an 89 and 95% increase, respectively, in all-cause mortality in sedentary participants holding all other variables constant. Conclusions: Sedentary lifestyle is strongly associated with all-cause mortality, independent of having moderate to severe depressive symptoms. Clinicians and researchers have an important role in promoting sustained and safe physical activity to improve survival. Other important modifiable targets to improve survival include depressive symptoms, low literacy, and low body mass index. Clinical Trial Registration— URL: https://www.clinicaltrials.gov .

Published: January 2019

Here, we provide the first report of an efficient method of in vivo delivery of MiRNA92b-3p mimic by intraperitoneal injection to whitefish, a Teleost fish. Juvenile whitefish were exposed to synthetic MiR92b-3p suspended in Invivofectamine 3.0 transfection reagent. After 24 and 48 h of the treatment, the blood, liver, spleen, brain, and heart of the fish were sampled to track the uptake of the synthetic miRNA and to assess its specific and off-target effects. RT-qPCR indicated that, within the first 24 h of treatment, MiR92b-3p levels were higher in the blood plasma, liver, and spleen of the injected fish than in the control fish that were administered only solvent vehicle, which was further confirmed by screening the organs with a fluorescently labeled MiR92b-3p probe. We then found that, 48 h after the injection, the mimic decreased the mRNA levels of its putative downstream targets (p53, cdkn1a, and pcna) by approximately 50%, which may indicate that MiR92b-3p was functional. Further profiling of mRNA expression in the liver by RNA sequencing showed perturbations that did not prompt global, specific silencing but instead produced significant differences in expression of a number of genes 48 h after transfection with the mimic. Neither histological nor ultrastructural analyses showed any pathological changes in the liver structure of the exposed fish, and biochemical measurements of the fishes’ blood did not differ between the experimental groups. Together, these results indicate that the MiR92b-3p mimic was effectively delivered to the liver of the injected fish, and that the short-term treatment did not cause any apparent toxic effects. This methodology of miRNA mimic delivery has utility not only for the study of miRNA-dependent silencing mechanisms in fish, but also gives reasons to anticipate significant progress in the development of both miRNA diagnostic markers and therapeutic targets in liver injury. Impact statement The delivery of short snippets of RNA, such as synthetic miRNA agents, is an essential step for achieving RNA-mediated knockdown, which has not been studied in sufficient detail in fish. Our results indicate that a MiR92b-3p mimic may be effectively delivered via intraperitoneal injection to the spleen and the liver of whitefish, and that it likely achieves functionality without causing any apparent toxic effects in the challenged animals. We report the novel finding that the MiR92b-3p mimic reduced the in vivo liver mRNA expression levels of its putative pro-apoptotic targets (p53, cdkn1a, and pcna), and important metabolic genes, e.g. cdo1. This shows that this methodology of MiR92b-3p mimic transfection in vivo may be a useful tool for studies that investigate the molecular pathways that confer pro-proliferative and anti-apoptotic phenotypes or those that regulate intracellular metabolism in fish and other vertebrates.
Concurrent Engineering, Knowledge Management, and Product Innovation

Published: January 2019

Evidence has shown that organizations seldom achieve the advantages offered by concurrent engineering (CE) practices. This may be attributed to the fact that the concept of CE is vague in terms of core elements and needs further investigation. In addition, despite the importance of CE and knowledge management in the context of product innovation, empirical investigation in this area is lacking. To this end, the goal of this research is to identify the critical dimensions of CE and empirically investigate the linkages between CE, knowledge management, and firm’s innovation. Based on a comprehensive literature review, the study conceptualizes the dimensions of CE as technical and social dimensions. Resource-based view of the firm and knowledge-based view are used to relate CE dimensions, knowledge management, and product innovation. Structural equation modeling was used for the testing of hypotheses. Empirical testing of the hypotheses was carried out by collecting data from 220 pharmaceutical firms operating in India. The findings of the study indicate that social dimensions of CE had a significant impact on knowledge management. Interestingly, the technical dimensions of CE did not have a significant impact on knowledge management. Furthermore, knowledge management was found to have a significant impact on product innovation. The implications of the findings for academicians and practitioners are discussed and directions for further research are also presented.

Authors: Yang Wenrui 
Published: January 2019

AbstractCurrent sports competitions are mostly broadcast in the form of live video or video files, and information detection for athletes and sports economic processes can also be carried out through image detection technology. However, from the current situation, we can see that sports image detection technology is still immature. Therefore, this study uses sports video as a material to analyze the application of sports image detection technology. In this study, image detection technology edge detection, grayscale processing, object capture, target recognition, etc. are combined with the actual needs of sports video to achieve a variety of needs for sports image detection. Simultaneously, this study has realized the recognition of athletes, motion recognition, sports behavior judgment, etc. and built a test platform to verify the effectiveness of this research method. The results show that the research method has certain practicality and can provide a theoretical reference for subsequent related research.

В настоящее время наблюдается рост количества детей, родившихся без отца. В статье представлены результаты изучения детско-родительских отношений в неполной (материнской) семье.Целью исследования является выявление типа родительского отношения в материнской семье.Предметом данной работы являются детско-родительские отношения в материнской семье. Объектами исследования были 60 подростков и 60 одиноких матерей, проживающие в сельском районе Республики Саха (Якутия).Исследование детско-родительских отношений было проведено с помощью опросника «Поведение родителей и отношение подростков к ним» (ADOR-сокращенно, подростки о родителях, опросник родительских отношений (А.Я. Варга, В.В. Столин), методика изучения структуры интегральной индивидуальности по 120 симптомам (Т.Ф. Базылевич).Выделены предпочитаемые одинокими матерями типы взаимоотношений с детьми подросткового возраста. Обнаружено, что негативное или положительное восприятие родительских отношений в значительной мере обусловлено полом подростков: стремление матери инфантилизировать ребенка воспринимается мальчиками как негативное, девочками как позитивное. Однако различия имеются в показателях внутри представителей одного пола в зависимости от сложившейся структуры индивидуальности подростков. Матери сыновей, принадлежащих к I типологическому синдрому индивидуальности, более склонны к отвержению, чем матери мальчиков с II типологическим синдромом.Результаты исследования могут быть применены школьными психологами и социальными педагогами.

Published: January 2019

Abstract. In this study, an electronic nose (E-nose) was used to evaluate the damage severity of tea plants, and a new evaluation index (mass loss) was introduced to reflect damage severity. Gas chromatography-mass spectrometer (GC-MS) was employed for proving the potential of the E-nose to detect tea plants with different damage severities. The number of pests attacking tea plants and the time under attack are two traditional evaluation indexes that are widely applied. The prediction performance of mass loss was compared with the number of pests and time under attack based on partial least squares regression (PLSR) according to the correlation coefficient (R2) and root mean square error (RMSE), and the results showed that the prediction performance of mass loss was better than that of the other two indexes. Three regression algorithms, namely PLSR, extreme learning machine for regression (ELMR), and support vector regression (SVR), were applied to predict mass loss, and their performances were compared. The results indicated that these three algorithms all had good performances, and SVR was the best. It could be concluded that E-nose is a feasible technique for evaluating the damage severity of tea plants, and mass loss is an appropriate evaluation index for damage severity.

Moisture Content Classification of Soil and Stalk Residue Samples from Spectral Data Using Machine Learning

Published: January 2019

Abstract. Remotely sensed spectral data are commonly used to quantify material properties in agricultural applications. Typically, a few distinct bands are selected and formulated into a reflectance index. Machine learning presents an alternative approach for quantifying material properties from spectral data due to the ease at which it can be used to process large datasets. This study aimed to test several commercially available machine learning algorithms using spectral data collected from moisture-controlled silt-loam soil and wheat stalk residue samples. The spectral data used in this analysis were previously used to develop a normalized difference water index (NDWI) for remotely quantifying the moisture content of agricultural background materials by selecting a pair of narrow-band wavelengths. However, results showed mixed performance for index-based processing. In this study, raw spectral data were preprocessed using partial least squares (PLS) regression to optimize the number of input components. The PLS components were fed into 20 different machine learning algorithms available in MATLAB, and the best two performing methods were compared to the index-based method. Cubic support vector machine (SVM) and ensemble bagged trees methods produced the highest composite prediction accuracies of 96% and 93%, respectively, for silt-loam soil samples and 86% and 93%, respectively, for wheat stalk residue samples. Prediction accuracy using the index-based method was 86% for silt-loam soil and 30% for wheat stalk residue. A potential limitation of both machine learning methods was the discrete classification of moisture content rather than the continuous output of the index-based method. However, the substantial improvement in prediction accuracy of individual samples likely outweighs concerns with limited precision.
