Published: January 2021

High-harmonic generation in the ultraviolet region is promising for wireless technology used for communications and sensing. However, small high-order nonlinear coefficients prevent us from obtaining high conversion efficiency and functional photonic devices. Here, we show highly efficient ultraviolet harmonic generation extending to the fifth order directly from an epsilon-near-zero indium tin oxide (ITO) film. The real part of the annealed ITO films was designed to reach zero around 1050 nm, matching with the central wavelength of an Yb-based fiber laser, and the internal driving electric field was extremely enhanced. A high energy conversion efficiency of

for 257.5 nm (fourth-order) and 206 nm (fifth-order) ultraviolet harmonic generation was obtained, which is at least 2 orders of magnitude higher than early reports. Our results demonstrate a new route for overcoming the inefficiency problem and open up the possibilities of compact solid-state high-harmonic generation sources at nanoscale.

Published: January 2021

Background
Currently, the SARS-CoV-2 promptly spread across China and around the world. However, there are controversies about whether preexisting chronic kidney disease (CKD) and acute kidney injury complication (AKI) are involved in the COVID-19 pandemic.

Measurements
Studies reported the kidney outcomes in different severity of COVID-19 were included in this study. Standardized mean differences or odds ratios were calculated by employing Review Manager meta-analysis software.

Results
Thirty-six trials were included in this systematic review with a total of 6395 COVID-19 patients. The overall effects indicated that preexisting CKD (OR = 3.28), complication of AKI (OR = 11.02), serum creatinine (SMD = 0.68), abnormal serum creatinine (OR = 4.86), blood urea nitrogen (SMD = 1.95), abnormal blood urea nitrogen (OR = 6.53), received continuous renal replacement therapy (CRRT) (OR = 23.63) were significantly increased in severe group than that in nonsevere group. Additionally, the complication of AKI (OR = 13.92) and blood urea nitrogen (SMD = 1.18) were remarkably elevated in the critical group than that in the severe group.

Conclusions
CKD and AKI are susceptible to occur in patients with severe COVID-19. CRRT is applied frequently in severe COVID-19 patients than that in nonsevere COVID-19 patients. The risk of AKI is higher in the critical group than that in the severe group.
Empirical evaluation of the association between daily living skills of adults with autism and parental caregiver burden
Authors: Marsack-Topolewski Christina N. , Samuel Preethy Sarah , Tarraf Wassim 
Published: January 2021

Background
Despite the joy of parenting, the burden of daily caregiving for children with autism spectrum disorders (ASD) can be overwhelming and constant. Parents can expect to provide enduring care for their children with ASD. Given that the majority of individuals with autism spectrum disorders (ASD) remain in their family homes well into adulthood, often the need for assistance with activities of daily living (ADLs) is placed on parents. Providing ongoing support to adult children who have difficulty with completing ADLs can increase parental caregiving demands. Therefore, the purpose of this study was to examine the relationship between the ability of adults with ASD to perform ADLs with parental perceptions of caregiver burden.

Methods
Quantitative analysis of cross-sectional multi-state data gathered electronically using Qualtrics from 320 aging parents of adults with ASD was conducted. Regression models were fit to examine the association of ADL challenges with total caregiver burden and its four domains (emotional, financial, time dependence, and developmental).

Results
Parental perceptions of caregiver burden decreased, particularly time dependence and developmental burden, when adult children were less dependent in ADLs, even after adjusting for parental health and behavioral challenges.

Conclusions
Findings support the need for family-centered interventions to improve the capacity of adults with ASD to perform ADLs independently.
Biomimetic Metamaterial Design Simulation and Evaluation for Building Acoustics by Impedance Measurements
Authors: Yazıcı Beyza , Gül Zühre Sü 
Published: January 2021

Abstract
This study investigates the potentials of acoustic metamaterial (AMM) applications in room and building acoustics by means of impedance tube experiments. With their extreme properties in either sound absorption or transmission loss, AMMs can perform better than traditional acoustic materials in buildings. Importantly, they are also more sustainable and hygienic than fibrous and porous materials. Depending on the matrix material used, AMMs can vary in transparency and color. Considering both their acoustic and aesthetic values, this study develops different types of metamaterial for possible uses as a partition wall, a surface layer, or a design element. The proposed metamaterials are primarily based on the exploration of ratios and forms from nature—the golden ratio, web-labyrinthine structures, genetic and neural systems such as deoxyribonucleic acid (DNA) molecules, and the synapse structures in the brain—reproduced on a subwavelength scale. These abstractions are then combined with the 3-D space coiling and 3-D labyrinth approaches of AMM design. Modules of the proposed AMMs are manufactured in a 3-D printer and tested in an impedance tube to estimate their normal incidence sound absorption coefficients and transmission loss characteristics. Based on the results obtained, the modules with the higher performances are used in the design of partition walls of varying heights. Two real-case architecture studios are simulated with and without the proposed AMM interventions over field test–tuned acoustical models of the studios to assess the effectiveness of such an approach in a possible acoustical design problem.

Background and Study Aim. The article is devoted to finding ways to optimize the training of players with cerebral palsy (CP). It is determined that testing and elaboration of criteria for assessing the level of physical fitness of football players with cerebral palsy can be used as a mean of evaluation the sportsmanship of football players of this nosology in training and competitive activities. The purpose of the study is to determine the level of physical and functional preparedness of football players with cerebral paralysis and to develop criteria for their evaluation during the intensive training period, taking into account the functional classes of athletes.
Material and Methods. 25 football players with cerebral palsy, candidates and members of the national team of Ukraine, three-time Paralympic champions, multiple world and European champions took part in the study voluntarily. Athletes of the selected group have 5-8 classes of the adapted classification of the International Association of Cerebral Palsy (CP-ISRA) for CP-Football. Biochemical parameters were studied before and after training work of different focus. The value of maximum oxygen consumption (MOC) was determined by means of bicycle ergometric testing. The physical state and level of physical fitness of football players were monitored during the study. The research was conducted on the basis of the research laboratory of Prydniprovsk State Academy of Physical Culture and Sport and on the basis of the Municipal Institution "Dnipropetrovsk Medical and Physical Dispensary" of the Dnipropetrovsk Regional Council.
Results. It was found that athletes with cerebral paralysis are able to adequately tolerate heavy physical loads. Football players with disabilities had biochemical parameters of blood sampling and registration of recovery processes of the cardiovascular system after training activities of different focus within the permissible norm for both healthy athletes. Obtaining such data became the basis for the intensification of training process, which promoted the development of motor skills of football players.
Conclusions. Obtained data were the basis for creation the criteria for assessing the level of physical fitness of football players depending on their sports classes. In future, this will allow coaches to determine the effectiveness of the training period, obtain information about the condition of players in training, in the recovery process. On this basis it will help to individualize the workload of players and adjust the training process.

AbstractAims. Ambulatory video‐EEG monitoring has been utilized as a cost‐effective alternative to inpatient video‐EEG monitoring for non‐surgical diagnostic evaluation of symptoms suggestive of epileptic seizures. We aimed to assess incidence of epileptiform discharges in ambulatory video‐EEG recordings according to seizure symptom history obtained during clinical evaluation.Methods. This was a retrospective cohort study. We queried seizure symptoms from 9,221 consecutive ambulatory video‐EEG studies in 35 states over one calendar year. We assessed incidence of epileptiform discharges for each symptom, including symptoms that conformed to a category heading, even if not included in the ILAE 2017 symptom list. We report incidences, odds ratios, and corresponding p values using Fisher's exact test and univariate logistic regression. We applied multivariable logistic regression to generate odds ratios for the six symptom categories that are controlled for the presence of other symptoms.Results. History that included motor symptoms (OR=1.53) or automatisms (OR=1.42) was associated with increased occurrence of epileptiform discharges, whereas history of sensory symptoms (OR=0.76) predicted lack of epileptiform discharges. Patient‐reported symptoms that were associated with increased occurrence of epileptiform discharges included lip‐smacking, moaning, verbal automatism, aggression, eye‐blinking, déjà vu, muscle pain, urinary incontinence, choking and jerking. On the other hand, auditory hallucination memory deficits, lightheadedness, syncope, giddiness, fibromyalgia and chronic pain predicted absence of epileptiform discharges. The majority of epileptiform discharges consisted only of interictal sharp waves or spikes.Conclusions. Our study shows that the use of ILAE 2017 symptom categories may help guide ambulatory video‐EEG studies.
Benign familial infantile epilepsy associated with KCNQ3 mutation: a rare occurrence or an underestimated event?

Published: January 2021

AbstractBenign familial infantile epilepsy (BFIE) is the most genetically heterogeneous phenotype among early‐onset familial infantile epilepsies. It has an autosomal dominant inheritance pattern with incomplete penetrance. Although PRRT2 is the most mutated gene detected in families with BFIE, other mutations in KCNQ2, SCN2A, and GABRA6 genes have also been described. To date, KCNQ3 mutations have been detected in only four patients with BFIE. Here, we describe the clinical pattern and course of an additional individual with BFIE associated with a novel missense heterozygous KCNQ3 c.1850G>C variant inherited by his unaffected father. The incidence of KCNQ3 mutations among BFIE patients is reported to be low in the literature, however, whether this is underestimated is unclear as not all current epilepsy gene panels include KCNQ3.
Encephalopathy related to status epilepticus during sleep due to a de novo KCNA1 variant in the Kv‐specific Pro‐Val‐Pro motif: phenotypic description and remarkable electroclinical response to ACTH

Published: January 2021

AbstractAlthough the classic phenotype of episodic ataxia type 1 (EA1) caused by variants in KCNA1 includes episodic ataxia and myokymia, further genotype‐phenotype correlations are difficult to establish due to highly heterogeneous clinical presentations associated with KCNA1 pathogenic variants. De novo variants in the paralogous Pro‐Val‐Pro motif (PVP) of KCNA2, an essential region for channel gating, have been reported to be associated with severe epilepsy phenotypes, including developmental and epileptic encephalopathies (DEE). Here, we describe the first patient with a DEE who developed an encephalopathy related to status epilepticus during sleep (ESES) and cerebellar signs, harbouring a variant in the Kv‐specific PVP motif of the KCNA1 gene. Interestingly, he showed a remarkable long‐term electroclinical response to IM ACTH therapy. This report extends the range of phenotypes associated with KCNA1 variants to include that of ESES, and suggests that ACTH therapy is likely to have a positive effect in patients with these variants.

Published: January 2021

AbstractWe present a rare patient clinically suspected to have mixed idiopathic generalized and focal epilepsy, which was supported by BOLD pattern based on EEG‐fMRI. A 37‐year‐old female with three types of refractory seizures starting at age six ‐ tonic with breathing difficulties and confusion, generalized tonic‐clonic, and focal with brief impairment of awareness and versive head movement, initially thought to represent atypical absences ‐ was evaluated by EEG‐fMRI. She was also shown to have three types of interictal epileptic discharges: generalized spike or polyspikes and slow waves, and left fronto‐temporal and right fronto‐temporal discharges. We assessed BOLD activation and deactivation for each type. For generalized patterns, the BOLD activation and deactivation were typical of that seen in primary generalized epilepsy. Whereas maximum activation for left fronto‐temporal EEG patterns was observed in the left superior frontal gyrus and posterior superior temporal gyrus, maximum activation for right fronto‐temporal patterns was bilateral in the right posterior middle temporal gyrus and left posterior middle temporal gyrus. The EEG‐fMRI results suggested that the patient had both refractory idiopathic generalized and focal epilepsy, and not a generalized epilepsy originating from a focus.

AbstractAutoscopic phenomena (AP) are characterized by seeing an image of oneself in extra‐personal space. These phenomena are rare and the anatomy of brain regions producing these phenomena is not well defined. We report anatomical electroclinical correlations during a stereoelectroencephalography‐recorded seizure with autoscopic hallucination (a form of AP in which the double of oneself is seen from an internal point of view). Seizure onset zone was quantified using the epileptogenicity index method (EI). Maximal EI values were obtained in the left lateral parietal cortex (supramarginal gyrus) and high values were also found in the left posterior‐superior insular cortex, left temporo‐occipital junction and contralateral inferior parietal lobule. Our case confirms the involvement of the inferior parietal lobule, temporo‐parieto‐occipital junction and posterior insula in the genesis of autoscopic hallucination.
How to distinguish seizures from non‐epileptic manifestations

Published: January 2021

AbstractThe first and most important step in establishing diagnosis of epilepsy consists of careful history taking from patients and witnesses. The clinical evaluation of the event will lead the indication for further diagnostic tests including e.g. EEG and MRI. Hence, identifying the paroxysmal event as epileptic or non‐epileptic is the very first step in the diagnostic process. Paroxysmal events pose a clinical challenge, as these are unpredictable and do not usually occur in the doctor's office. History taking, hunting for witness reports and home‐video recordings are the main tools to conclude whether a paroxysmal event is a seizure or not. In this review, we describe the most common differential diagnoses of epileptic seizures, including syncope, psychogenic non‐epileptic seizures, as well as a variety of paroxysmal conditions and behaviours of all age groups. Misdiagnosis of non‐epileptic events as epilepsy may not only defer the correct diagnosis and treatment but also poses additional risk by prescribing antiepileptic drugs unnecessarily. Moreover, missing the diagnosis of epilepsy implies risk of additional seizures and therefore possibly injuries, sudden death in people with epilepsy, or status epilepticus. Studies have shown that patient and witness accounts are unreliable in a high percentage of cases. Therefore, the core competency of doctors and medical professionals assessing paroxysmal events is knowledge of the clinical features that help define the different aetiologies, thus empowering them to establish the most accurate appraisal of an event.

Naive Bayes Classifier Optimization on Sentiment Analysis of Hotel Reviews
Authors: Khomsah Siti 
Published: January 2021

<p class="JGI-AbstractIsi">Feature extraction plays an important role in the sentiment analysis process, especially of text data. The Naive Bayes Classifier performs well on low feature dimensions. However, the accuracy provided is not optimal. To acquire optimal machine learning model, information gain method, evolutionary algorithm, and swarm intelligent algorithm are applied. The objective of this study is to determine the performance of the Particle Swarm Optimization (PSO) to optimize the Naive Bayes Classifier. Vectorization of words is carried out using TF-IDF. In order to produce high PSO performance, the PSO-NBC model is tested with several parameters, namely the number of particles (k = 3), setting of the number of iterations and inertia weight, individual intelligence coefficient (c1 = 1), and social intelligence coefficient (c2 = 2). Inert weight is calculated using the formulation (w = 0.5+ Rand ([- 1,1])). In conclusion, PSO is able to solve the problem space of text-based sentiment analysis. PSO is able to optimize the accuracy of Naive Bayes at a value of 89% to 91.76%. PSO performance is determined by the parameters used, especially the number of particles, the number of iterations, and the weight of inertia. A large number of particles accompanied by an increase in inertia weight can increase accuracy. The number of particles 20-30 has reached the optimal accuracy.</p>

Abstract
Introduction CTKUB use in patients presenting to Emergency Department (ED) with suspected renal colic has increased by 10-fold over last few years. However, its impact on the urological intervention is not fully known.Methods We performed a retrospective study of adult patients, presenting consecutively to ED with suspected renal colic who underwent CTKUB from January to June 2014. We calculated descriptive summary statistics for analysis to determine the association of predefined radiological and patients’ characteristics on the urological intervention.Results Of the 282 patients enrolled in the study, 38% had stones. Commonest locations of stone were ureter (15%), uretero-vesical junction (12.4%). Of the study participants, 2% of the patients underwent urological intervention. Chi Square analysis did not find any significant associations between radiological or patients related characteristics and urological interventionConclusion There was no significant correlation between CTKUB findings or patients’ characteristics and urological intervention in this study cohort.
