5 and NO2 as a result of the containment measures and suspension of activities implemented by the Peruvian government. The concentrations of O3 significantly increased (11% and 170%) as a result of the decrease in the concentration of NO2, confirming that the study area is a hydrocarbon-limited system, as previously reported. The results obtained contribute to the assessment by the regulatory agencies of the possible strategies of control and monitoring of air pollution in the study area.

Since the outbreak of COVID-19 and the non-pharmaceutical interventions introduced to contain it, searches for socially distanced activities have trended. We hypothesize that trends in the volume of search queries related to activities associated with COVID-19 transmission correlate with subsequent COVID-19 caseloads. We present a preliminary analytics framework that examines the relationship between Google search queries and the number of newly confirmed COVID-19 cases in the United States. We designed an experimental tool with search volume indices to track interest in queries related to two themes isolation and mobility. Our goal was to capture the underlying social dynamics of an unprecedented pandemic using alternative data sources that are new to epidemiology. Our results indicate that the net movement index we defined correlates with COVID-19 weekly new case growth rate with a lag of between 10 and 14 days for the United States at-large, as well as at the state level for 42 out of 50 states with the exception of 8 states (DE, IA, KS, NE, ND, SD, WV, WY) from March to June 2020. In addition, an increasing caseload was seen over the summer in some southern US states. A sharp rise in mobility indices was followed by a sharp increase, respectively, in the case growth data, as seen in our case study of Arizona, California, Florida, and Texas. A sharp decline in mobility indices is often followed by a sharp decline, respectively, in the case growth data, as seen in our case study of Arizona, California, Florida, Texas, and New York. The digital epidemiology framework presented here aims to discover predictors of the pandemic's curve, which could supplement traditional predictive models and inform early warning systems and public health policies.In recent years, SenticNet and OntoSenticNet have represented important developments in the novel interdisciplinary field of research known as sentic computing, enabling the development of a variety of Sentic applications. In this paper, we propose an extension of the OntoSenticNet ontology, named DomainSenticNet, and contribute an unsupervised methodology to support the development of domain-aware Sentic applications. We developed an unsupervised methodology that, for each concept in OntoSenticNet, mines semantically related concepts from WordNet and Probase knowledge bases and computes domain distributional information from the entire collection of Kickstarter domain-specific crowdfunding campaigns. Subsequently, we applied DomainSenticNet to a prototype tool for Kickstarter campaign authoring and success prediction, demonstrating an improvement in the interpretability of sentiment intensities. DomainSenticNet is an extension of the OntoSenticNet ontology that integrates each of the 100,000 concepts included in OntoSenticNet with a set of semantically related concepts and domain distributional information. The defined unsupervised methodology is highly replicable and can be easily adapted to build similar domain-aware resources from different domain corpora and external knowledge bases. Used in combination with OntoSenticNet, DomainSenticNet may favor the development of novel hybrid aspect-based sentiment analysis systems and support further research on sentic computing in domain-aware applications.Neuroblastic tumors are the most common extracranial solid tumors in children. They are manifested by different clinical presentations ranging from cord compression symptoms to asymptomatic cases. BMH21 A 2.5-year girl with a history of vaginal delivery at 39 gestational weeks and low Apgar score presented by repeated episodes of urinary tract infections and progressive paraplegia started at the age of 8 months. Brain MRI and EEG were normal. Voiding cystourethrography revealed grade II vesicoureteral reflux in the left kidney. Lumbar MRI with and without contrast showed a dumbbell shape mass, the hyper signal in T2 -weighted image and low signal in T1 -weighted image, extramedullary, and intramural with mass effect on the cord. Microscopic examination of tissue obtained by surgery reported ganglioneuroma. Our case was interesting because of her presentation, neurogenic bladder associated with repeated episodes of urinary tract infections, and secondary paraplegia. Neurogenic bladder dysfunction is rarely reported in cases with ganglioneuroma.Coronavirus disease 2019 (COVID-19) is caused by the seventh coronavirus, known as the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2). Children often have milder diseases than adults with very rare mortality. Gastrointestinal manifestations and a mild increase in liver enzymes have been reported in 8.8% to 53% of COVID-19 cases. However, liver failure is extremely rare and has not been reported so far in the literature. The prevalence of comorbidities is not clear in children with COVID-19. Here, we reported a fatal case of simultaneous pneumonia secondary to SARS-CoV-2and acute liver failure in a 14-year-old boy with liver cirrhosis.The global coronavirus disease 2019 (COVID-19) pandemic appears to have some streaks of severity in pediatrics. These streaks include variable signs of respiratory distress, a new entity called multi-system inflammatory syndrome, and some evidences of neurological symptoms involving both central and peripheral nervous systems. Here, we described the first pediatric patient with COVID-19 who presented with acute transverse myelitis. An 11-year-old otherwise healthy girl presented to our clinic with acute onset of lower limbs paresis, urinary and fecal retention, alongside epigastric pain, and fever for 3 days. A neurological examination revealed a severe flaccid paraplegia in her lower limbs associated with a sensory level at T5. She was evaluated systematically for all probable causes of her symptoms, and finally, due to having a positive nasopharyngeal PCR test, she was considered to suffer from post-COVID-19 transverse myelitis. She underwent intravenous-immunoglobulin, methylprednisolone pulse, and other supportive cares without obvious results.
