Effect of supraneural transforaminal epidural steroid injection combined with caudal epidural steroid injection with catheter in chronic radicular pain management: Double blinded randomized controlled trial.
Authors: Munjupong Sithapan , Kumnerddee Wipoo 
Published: July 2020

Background: Epidural steroid injection (ESI) has been used in managing chronic radicular pain. Regarding various techniques of ESI, the synergistic effect of caudal ESI (CESI) on transforaminal ESI (TFESI) in chronic lumbosacral radicular pain in prospective randomized controlled trial has not been determined. Methods: A total of 54 eligible patients with lumbosacral radicular pain were randomly allocated to undergo TFESI plus CESI (TC group) or TFESI alone (T group). The effective response to treatment was predefined by at least a 30% reduced verbal numerical rating scale (VNRS) from baseline between group comparison and the functional outcomes as measured by improved Oswestry Disability Index by least 15 points from baseline. All participants were evaluated using a single blinded outcome assessor before the procedure and at 1, 3 and 6 months after the procedure. P <0.05 was considered as statistically significant. Results: Average VNRS reduced significantly from baseline after receiving procedure at 1, 3 and 6 months in both groups (P-value <0.05). The TC group exhibited more effective and showed significant pain relief compared with the T group at 3 months (P=0.01). However, no statistical difference was observed between sub group analysis in pain relief and insignificant difference between group comparisons of functional outcomes. Conclusions: A treatment combining TFESI and CESI showed significant pain relief over TFESI alone at 3 months. No effect was found concerning functional evaluation.

Background: Disability brings challenges and demands in the family and society which last for a long time. Children that are affected by disability are often kept at home, without access to opportunities other children might have, and education is one of the most effective ways to break the cycle of discrimination and poverty. Malaysia is committed to achieving the Sustainable Development Goals, and teacher quality issues are among the Ministry of Education's focuses to ensure a successful journey for pupils with disabilities. In this study, we evaluated the competency, knowledge and implementation practices of teachers serving government schools in West Malaysia regarding teaching children with autism spectrum disorder (ASD). Methods: 832 primary teachers from different states of West Malaysia participated in a web-based survey that assessed self-reported competency, knowledge and implementation practices with regards to managing children with autism spectrum disorder. Results: Respondents rated themselves as quite competent, and believed that they were knowledgeable regarding ASD and could implement ASD tasks. Frequency of training was a consistent predictor of competency. Respondents who had never attended a training course had significantly lower self-competency, lower level of knowledge, and lower implementation ratings than those who had attended even one course. Conclusions: Investments in training teachers on ASD are highly recommended to ensure these students are provided with quality of education they deserve.
Information Content of Aggregate Implied Volatility Spread
Authors: Han Bing , Li Gang 
Published: July 2020

Aggregate implied volatility spread (IVS), defined as the cross-sectional average difference in the implied volatilities of at-the-money call and put equity options, is significantly and positively related to future stock market returns at daily, weekly, and monthly to semiannual horizons. This return predictive power is incremental to existing return predictors, and it is significant both in sample and out of sample. Furthermore, IVS can forecast macroeconomic news up to one year ahead. The return predictability concentrates around macro news announcement. Common informed trading in equity options offers an integrated explanation for the ability of IVS to predict both future stock market returns and real economic activity.This paper was accepted by Tyler Shumway, finance.

O estado de coisas inconstitucional no cenário de acesso ao aborto legal no brasil
Authors: Alves Henrique Rosmaninho 
Published: July 2020

O presente artigo faz uma análise do cenário existente no Brasil para garantir o acesso ao aborto legal às mulheres que tenham o direito de realizá-lo. Busca-se identificar se o quadro de infraestrutura e informações disponível para concretizar esse direito, bem como se o número de mulheres que deixam de ser atendidas anualmente configuraria o instituto do estado de coisas inconstitucional. Para tanto se investigou os dados relativos ao abortamento legal e inseguro no Brasil obtidos pelo grupo “Católicas pelo Direito de Decidir”, pelo “Article 51”, pela pesquisadora Débora Diniz e divulgados pelo Ministério da Saúde. Trata-se de uma pesquisa jurídico-sociológico, bibliográfica, qualitativa, com emprego de raciocínio dedutivo. Ao final conclui-se que a perene precariedade ou inexistência completa de infraestrutura pública de saúde disponível para promover o acesso ao aborto legal e seguro, bem como a ausência de informações sobre os direitos sexuais e reprodutivos das mulheres por parte dos órgãos oficiais de saúde configura o estado de coisas inconstitucional e faz-se duas sugestões para reverter esse quadro.

Published: July 2020

Abstract
Dynamic ground and ground-structure responses are heavily dependent on the soil shear wave velocity. During seismic excitation, soil stiffness inferred from the shear wave velocity (Vs) might change significantly and affect the overall system response. In this study, an instrumentation and analysis framework was developed to allow for continuous estimation of Vs during dynamic/seismic excitation. The framework is presented along with representative applications during shake table testing of saturated sand strata. For that purpose, results from two different 1-g shake table tests conducted in a laminar soil container are examined and analyzed. In this context, evolution of the soil Vs profile during the shaking event is tracked and documented. The experimental setup, test procedure, and test results are described. Time histories of Vs at different depths within the sand strata are discussed. Overall, the developed techniques can be conveniently included in routine 1-g and centrifuge shake table experimentation efforts, when properly accounting for the differences between sizes of 1 g and centrifuge models.
The prevention paradox applies to some but not all gambling harms: Results from a Finnish population-representative survey
Authors: Browne Matthew , Volberg Rachel , Rockloff Matthew , Salonen Anne H. 
Published: July 2020

AbstractBackground and aimsThe Prevention Paradox (PP) suggests that a large proportion of aggregate harm from gambling occurs to people who do not have a gambling disorder. However, it has not yet been tested using a population-representative sample. We aimed to test whether the PP applies to gambling in Finland. The prevalence rates of diverse harmful consequences from gambling were surveyed amongst a population-representative sample of past-year gamblers.MethodsThe study used first wave data (N= 7,186) of Finnish Gambling Harms survey, collected via online and postal surveys in 2017. A subset of 3,795 adults (≥18 years), who had gambled at least monthly in 2016, were selected for analysis.MeasurementsGambling-related harms were evaluated with the 72-item Harms Checklist. Problem and Pathological Gambling Measure (PPGM) measured respondents’ probable disordered gambling from the subset of items for impaired control (4 questions) and other issues (3 questions).FindingsConsistent with previous findings, the majority of harms were reported by those in the less severe PPGM categories (i.e. scoring <5). However, considering each domain separately, this was true only for financial, emotional/psychological, and work/study harms. The PP was not supported for health, relationship, or social deviance harms.ConclusionsThe population prevalence of the most serious harms (e.g. unsafe living conditions) is concentrated among those with severe impaired control issues. However, even excluding the ∼15% of harms occurring to occasional gamblers, most financial, emotional and work/study impacts occur to those with lower levels of control issues. Efforts at harm reduction should focus on the entire spectrum of issues that people experience from their gambling.

AbstractObjectivesWe examined serial mediating roles of low self-control and aggression in explaining relationships between levels of inattention and hyperactivity problems (IHPs) and severity of Internet gaming disorder (IGD) features when exposed to online games among adolescents without Attention deficit hyperactivity disorder (ADHD) stratified by gender using three-wave longitudinal study.MethodThe sample comprised a total of 1,732 family dyads from a study that was conducted among seventh graders without diagnoses of ADHD at baseline. Levels of IHPs were assessed by the parent reported Korean version of the ADHD rating scale at baseline (wave1). Severity of IGD features was assessed by the Internet Game Use-Elicited Symptom Screen (IGUESS) at wave3. Both levels of self-control (wave1) and aggression (wave2) were assessed by self-report. The mediating role of low self-control and aggression in the relationships between level of IHPs and severity of IGD were evaluated using serial mediation analysis separately for each gender.ResultsLevels of IHPs were related directly to severity of IGD features in both genders. The indirect effects via low self-control were also significant in both genders, however, the indirect effects via aggression was significant only in women. The serial mediation effect via low self-control and aggression between levels of IHPs and IGD features was significant in both genders (men, coefficient:0.009, 95%CI 0.005–0.019; women, coefficient:0.010, 95%CI:0.005–0.026).ConclusionWe revealed a possible mechanism underlying a serial mediation chain from low self-control to aggression explaining the effects of IHPs on severity of IGD features. However, this conclusion should be taken with a caution, because the effect sizes were very low.
Gamblers' attitudes towards money and their relationship to gambling disorder among young men
Authors: Sleczka Pawel , Braun-Michl Barbara , Kraus Ludwig 
Published: July 2020

AbstractBackground and aimsMoney plays a central role in gambling, and understanding the different attitudes of gamblers towards it might benefit both prevention and treatment of gambling-related problems. This study describes the development of a new German measure of attitudes to money and the differences in these attitudes between male non-gamblers, occasional, frequent and problem gamblers. Furthermore, it investigates the cross-sectional and longitudinal associations between attitudes towards money and the severity of gambling disorder.MethodsAn online study was conducted among 2,584 men aged 18–25 years, recruited via the Munich citizen registry. Additionally, a sample ofn= 105 Facebook users was included in part of the analyses. Frequent and problem gamblers were invited to a 12-month follow-up. Apart from gambling participation and related problems, the questionnaire included items from existing scales measuring attitudes to money.ResultsThree factors underlying a new 12-item German Scale of Money Attitudes (SMAG) were identified:success,budgetingandevil. Compared with other groups, participants reporting any gambling problems scored highest insuccessand lowest inbudgeting.Budgetingwas associated with gambling-related problems in both cross-sectional and longitudinal analyses and strengthened the relationship between associating money with success and gambling disorder.DiscussionFor problem gamblers, money is important as a personal symbol of success. This attitude has an especially negative effect on gambling-related problems in individuals who handle money irresponsibly. Spending and winning money might play an important role in maintaining self-esteem among gamblers and thus hinder their attempts to quit.

Published: July 2020

AbstractBackground and aimsIn recent years, Internet Gaming Disorder (IGD) has been recognized as a mental health problem. Although research has found that social anxiety, motives, the preference for online social interactions (POSI), and metacognitions about online gaming are independent predictors of IGD, less is known about their relative contribution to IGD. The aim of the current study was to model the relationship between social anxiety, motives, POSI, metacognitions about online gaming, and IGD.MethodsFive hundred and forty three Italian gamers who play more than 7 h a week (mean age = 23.9 years; SD = 6.15 years; 82.5% males) were included in the study. The pattern of relationships specified by the theoretical model was examined through path analysis.ResultsResults showed that social anxiety was directly associated with four motives (escape, coping, fantasy, and recreation), POSI, and positive and negative metacognitions about online gaming, and IGD. The Sobel test showed that negative metacognitions about online gaming played the strongest mediating role in the relationship between social anxiety and IGD followed by escape, POSI, and positive metacognitions. The model accounted for 54% of the variance for IGD.Discussion and conclusionsOverall, our findings show that, along with motives and POSI, metacognitions about online gaming may play an important role in the association between social anxiety and IGD. The clinical and preventive implications of these findings are discussed.

Published: July 2020

AbstractBackground and aimsBehavioral addictions such as gambling and gaming disorder are significant public health issues that are of increasing importance to policy makers and health care providers. Problem gambling and gaming behaviors have been identified as being associated with externalizing and internalizing problems, with theoretical models suggesting that both conduct problems and depressive symptoms may be significant risk factors in the development of problem gambling and gaming. As such, the purpose of this systematic review is to provide an overview of research identifying the relationship between conduct problems, depressive symptoms and problem gambling and gaming among adolescents and young adults.MethodsSystematic literature searches in accordance with PRISMA guidelines found 71 eligible studies that met the inclusion criteria, 47 for problem gambling, 23 for problem gaming and one for both problem behaviors.ResultsBased on cross-sectional evidence, both problem gambling and gaming are consistently concurrently associated with conduct problems and depressive symptoms. Longitudinal evidence appears to be clearer for conduct problems as a risk factor for problem gambling, and depressive symptoms as a risk factor for problem gaming. However, both risk factors appear to increase the risk for these problem behaviors.Discussion and ConclusionsResults from the literature review suggest that problem gambling and gaming are associated with the presence of conduct problems and depressive symptoms, with the potential of sharing common etiological factors. Additional research is necessary to confirm these longitudinal relationships with an emphasis on investigating the interaction of both early conduct problems and depressive symptoms.

Se estima que los trastornos musculoesqueléticos constituyen la patología más frecuente, que afectan la salud de los teletrabajadores, la productividad en las organizaciones y generan una gran cantidad de casos de discapacidad. En este sentido el presente trabajo tuvo el objetivo de determinar la prevalencia de trastornos musculoesqueléticos y la asociación con factores de riesgo ergonómico en los docentes universitarios que realizan teletrabajo en tiempos de COVID-19 en universidades de Lima, Perú, en el año 2020. Para ello se realizó un estudio analítico de corte transversal y de enfoque cuantitativo. La población de estudio estuvo constituida por 110 docentes universitarios que se encontraban realizando teletrabajo en el semestre 2020-I, durante el confinamiento social por el COVID-19, en Lima, Perú. Se aplicó el cuestionario Nórdico de Kuorinka para obtener información con respecto a los síntomas musculoesqueléticos en regiones del cuerpo, tales como: hombros, codos, muñecas, cuello, región dorsal y región lumbar; sucedidos en los últimos 12 meses hasta 07 días antes de aplicado el cuestionario. Los resultados evidencian la prevalencia de los trastornos musculoesqueléticos por segmento fue en el 100% (n=110) de la población encuestada. Se encontró con mayor frecuencia en la columna dorso-lumbar 67.27 % (n=74) y en el cuello 64.55% (n=71), en menor porcentaje en el hombro 44.55% (n=49), muñeca/mano 38.18% (n=42) y en el codo/antebrazo 19.09% (n=21). Los docentes asociaron estos trastornos musculoesqueléticos a posturas prolongadas en el rango de 26.80%-50.00% y 12.50%-26.80% a largas jornadas laborales. El grupo etario mayoritario fue 39.09% (n=43) de 41 a 50 años y 28.18% (n=31) de 31 a 40 años. El 70.91% (n=78) fueron varones y 29.09% (n=32) mujeres. Concluyéndose de esta manera que hay una elevada prevalencia de trastornos musculoesqueléticos en los docentes universitarios, principalmente en la columna dorso-lumbar y cuello; y existe asociación de estos trastornos con factores de riesgo ergonómico como postura prolongada y largas jornadas laborales.
Experimental pull-out tests and design indications for strength anchors installed in masonry walls
Authors: Giresini Linda , Puppio Mario Lucio , Taddei Francesca 
Published: July 2020

AbstractThis study deals with the identification of the mechanical behavior of chemical anchors embedded in masonry walls. 108 pull-out tests are carried out in five types of masonry walls built with clay brick or vertically perforated units with cement mortar. Different parameters are taken into account: embedment depths, masonry type, anchor position (injection either in brick units or in mortar joints). The axial load capacity and the failure mode are observed for each test. The results are examined by means of elastic and plastic models assessing the efficiency of anchors installed in headers, stretchers or mortar joints. The anchors injected in mortar joints are shown to have much greater pull-out capacity than that found for anchors in bricks. Passing from 90 to 160 mm of embedment depth, a minimum increase by 40% of pull-out strength is observed. The most common failure modes are the sliding failure, which occurs for short anchors or weak masonry, and mixed sliding/cone failure, for long anchors or strong masonry. An analytical model is proposed to design anchors in order to avoid or at least to limit brittle masonry failures and to identify the field of application of uniform stress models.
