Authors: Vetráb Mercedes , Gosztolya Gábor 
Published: August 2022

Abstract
The problem of varying length recordings is a well-known issue in paralinguistics. We investigated how to resolve this problem using the bag-of-audio-words feature extraction approach. The steps of this technique involve preprocessing, clustering, quantization and normalization. The bag-of-audio-words technique is competitive in the area of speech emotion recognition, but the method has several parameters that need to be precisely tuned for good efficiency. The main aim of our study was to analyse the effectiveness of bag-of-audio-words method and try to find the best parameter values for emotion recognition. We optimized the parameters one-by-one, but built on the results of each other. We performed the feature extraction, using openSMILE. Next we transformed our features into same-sized vectors with openXBOW, and finally trained and evaluated SVM models with 10-fold-crossvalidation and UAR. In our experiments, we worked with a Hungarian emotion database. According to our results, the emotion classification performance improves with the bag-of-audio-words feature representation. Not all the BoAW parameters have the optimal settings but later we can make clear recommendations on how to set bag-of-audio-words parameters for emotion detection tasks.
Distributed optimal control problems driven by space-time fractional parabolic equations

Published: August 2022

Abstract
We study distributed optimal control problems, governed by space-time fractional parabolic equations (STFPEs) involving time-fractional Caputo derivatives and spatial fractional derivatives of Sturm-Liouville type. We first prove existence and uniqueness of solutions of STFPEs on an open bounded interval and study their regularity. Then we show existence and uniqueness of solutions to a quadratic distributed optimal control problem. We derive an adjoint problem using the right-Caputo derivative in time and provide optimality conditions for the control problem. Moreover, we propose a finite difference scheme to find the approximate solution of the considered optimal control problem. In the proposed scheme, the well-known L1 method has been used to approximate the time-fractional Caputo derivative, while the spatial derivative is approximated using the Grünwald-Letnikov formula. Finally, we demonstrate the accuracy and the performance of the proposed difference scheme via examples.
What Modifies the Effect of an Exercise Treatment for Chronic Low Back Pain? A Meta-epidemiologic Regression Analysis of Risk of Bias and Comparative Effectiveness
Authors: Niederer Daniel , Weippert Matthias , Behrens Martin 
Published: August 2022

OBJECTIVE: To investigate how risk of bias and intervention type modify effect sizes of exercise interventions that are intended to reduce chronic low back pain intensity. DESIGN: Systematic review with meta-epidemiologic regression analysis. LITERATURE SEARCH: PubMed, CENTRAL, Embase, and CINAHL (until January 31, 2021). STUDY SELECTION CRITERIA: Systematic reviews with meta-analyses of randomized controlled exercise trials. DATA SYNTHESIS: The dependent variable was pain, calculated as standardized mean difference (SMD). Potential effect modifiers were risk of bias, exercise modes, study, and meta-analyses characteristics. Multilevel meta-regressions and inverse variance-weighted meta-regressions with random intercepts were modelled. RESULTS: Data from 26 systematic reviews (k = 349 effect sizes, n = 18,879 participants) were analysed. The overall mean effect was SMD: −0.35 (k = 349, [95% CI −0.02 to −0.7]). There was a clinically relevant effect overestimation in studies with a high risk of bias due to missing outcomes (each k = 197, Beta coefficient = −1.9 [95% CI −2.9 to −.9]) and low sample size (B = 0.01 [.001 to .01], [ie, one participant more leads to an SMD decrease of 0.01]). There was a clinically relevant underestimation of the effect when studies were at high risk of bias in allocation concealment (B = 1.3 [.5 to 2.1]) and outcome measurement (B = 1.3 [.44 to 2.0]). Motor control and stabilization training (B = −1.3 [−2.3 to −.37]) had the largest effects; stretching (B = 1.3 [−.03 to .5]) had the smallest effect. CONCLUSIONS: The effects of exercise trials at high risk of bias may be overestimated or underestimated. After accounting for risk of bias, motor control and stabilization exercises may represent the most effective exercise therapies for chronic low back pain.

Published: August 2022

Background:
The aim of the study was to describe the origin, course, and termination of frontal aslant tract (FAT) in the Mexican population of neurosurgical referral centers.

Methods:
From January 2018 to May 2019, we analyzed 50 magnetic resonance imaging (MRI) studies in diffusion tensor imaging sequences of patients of the National Institute of Neurology and Neurosurgery “Manuel Velasco Suárez.” Five brains were fixed by the Klingler method and dissected in the neurosurgery laboratory of the Hospital Civil de Guadalajara to identify the origin, trajectory, and ending of the FAT.

Results:
FAT was identified in 100% of the MRI and brain dissections. The origin of the FAT was observed in 63% from the supplementary premotor area, 24% from the supplementary motor area, and 13% in both areas. Its ending was observed in the pars opercularis in 81%, pars triangularis in 9%, and in both pars opercularis and ventral premotor area in 10% in the magnetic resonance images, with a left side predominance. In the hemispheres dissections, the origin of FAT was identified in 60% from the supplementary premotor area, 20% from the supplementary motor area, and 20% in both areas. Its ending was observed in the pars opercularis in 80% and the pars triangularis in 20%. It was not identified as an individual fascicle connected with the contralateral FAT.

Conclusion:
In the Mexican population, FAT has a left predominance; it is originated more frequently in the supplementary premotor area, passes dorsal to the superior longitudinal fascicle II and the superior periinsular sulcus, and ends more commonly in the pars opercularis.
Therapeutic strategy of severe circular calcified carotid plaque with hemodynamic impairment: A patient treated by carotid endarterectomy following balloon angioplasty to prevent hyperperfusion
Authors: Marutani Takaki , Kashiwazaki Daina , Yamamoto Shusuke , Akioka Naoki , Hori Emiko , Kuroda Satoshi 
Published: August 2022

Background:
Cerebral hyperperfusion syndrome (HPS) is a serious complication. Recently, staged angioplasty has been reported as an effective strategy to avoid HPS. Severe calcification has been reported as contraindication of carotid artery stenting (CAS). In these cases, carotid endarterectomy (CEA) might be an alternative second stage treatment. We present a case of severe circular calcified plaque with hemodynamic impairments, treated with CEA following percutaneous transluminal angioplasty (PTA) to prevent HPS.

Case Description:
A 77-year-old woman presented with severe stenosis at the proximal left internal carotid artery. A CT scan of the neck demonstrated circular calcification. 123I-iodoamphetamine single-photon emission computed tomography (123I-IMP SPECT) showed reductions in cerebral blood flow (CBF) and cerebral vascular reserve in the left hemisphere. Staged therapy was subsequently performed as this patient had a high risk of HPS after conventional CAS or CEA. In the first stage, PTA was performed under local anesthesia. Two days after the procedure, 123I-IMP SPECT revealed improvements in CBF. There were no neurological morbidities. CEA was then performed under general anesthesia 7 days later, for the second stage. We found a calcified plaque with a large thrombus at its proximal end. A hematoxylin-eosin stain of the thrombus showed mostly intact and partially lytic blood cells. Postoperative 123I-IMP SPECT revealed CBF was improved, with no hyperperfusion immediately and 2 days after CEA. The patient was discharged with no neurological deficits.

Conclusion:
CEA following PTA for severe circular calcified plaque can be an alternative treatment strategy to prevent HPS. A disadvantage is the formation of thrombi. Early CEA should be considered if thrombus formation is suspected.

A Roda da Central: a capoeira de rua carioca, décadas de 1950 a 1970
Authors: Röhrig Assunção Matthias 
Published: August 2022

A Roda da Central acontecia durante o carnaval no Rio de Janeiro desde os anos 1950 até a construção do sambódromo, em 1983. A roda não parava – eram 24 horas por dia, durante os três dias e noites do carnaval, em um local improvisado, entre o glamoroso desfile oficial das escolas de samba na Avenida Presidente Vargas e a estação de trens Central do Brasil, que liga a cidade a seus subúrbios, e por onde circulava grande parte dos foliões. Apesar da farta documentação sobre os desfiles, nenhum registro ou foto documenta a Roda da Central. Este artigo se baseia no testemunho precioso de quinze mestres que protagonizaram essa roda. Suas memórias documentam os tipos de ritmos tocados e os jogos duros e frequentemente violentos que aconteciam num contexto volátil de repressão e clientelismo. Trabalhadores portuários, na sua maioria negros, foram inicialmente os principais personagens, gradualmente substituídos por uma geração mais jovem e diversificada, para quem jogar seu primeiro jogo na Roda da Central era um rito de passagem. O exemplo da Roda da Central mostra como a história oral pode reequilibrar a narrativa da história da capoeira, muitas vezes centrada em sua modalidade oficial mais próxima da ginástica desportiva.

Etiology- and region-specific characteristics of transependymal cerebrospinal fluid flow
Authors: Yang Peter H. , Almgren-Bell Alison , Gu Hongjie , Dowling Anna V. , Pugazenthi Sangami , Mackey Kimberly , Dupépé Esther B. , Strahle Jennifer M. 
Published: August 2022

OBJECTIVE
Transependymal flow (TEF) of CSF, often delineated as T2-weighted hyperintensity adjacent to the lateral ventricles on MRI, is a known imaging finding, usually in the setting of CSF flow disturbances. Specific radiological features of TEF and their relationships with clinical markers of hydrocephalus and underlying disease pathology are not known. Here, the authors describe the radiological features and clinical associations of TEF with implications for CSF circulation in the setting of intracranial pathology.

METHODS
After obtaining IRB review and approval, the authors reviewed the radiological records of all patients who underwent intracranial imaging with CT or MRI at St. Louis Children’s Hospital, St. Louis, Missouri, between 2008 and 2019 to identify individuals with TEF. Then, under direct review of imaging, TEF pattern, degree, and location and underlying pathology and other radiological and clinical features pertaining to CSF circulation and CSF disturbances were noted.

RESULTS
TEF of CSF was identified in 219 patients and was most prevalent in the setting of neoplasms (72%). In 69% of the overall cohort, TEF was seen adjacent to the anterior aspect of the frontal horns and the posterior aspect of the occipital horns of the lateral ventricles, and nearly half of these patients also had TEF dorsal to the third ventricle near the splenium of the corpus callosum. This pattern was independently associated with posterior fossa medulloblastoma when compared with pilocytic astrocytoma (OR 4.75, 95% CI 1.43–18.53, p = 0.0157). Patients with congenital or neonatal-onset hydrocephalus accounted for 13% of patients and were more likely to have TEF circumferentially around the ventricles without the fronto-occipital distribution. Patients who ultimately required permanent CSF diversion surgery were more likely to have the circumferential TEF pattern, a smaller degree of TEF, and a lack of papilledema at the time of CSF diversion surgery.

CONCLUSIONS
CSF transmigration across the ependyma is usually restricted to specific periventricular regions and is etiology specific. Certain radiological TEF characteristics are associated with tumor pathology and may reflect impaired or preserved ependymal fluid handling and global CSF circulation. These findings have implications for TEF as a disease-specific marker and in understanding CSF handling within the brain.
Diagnostic Yield of Chilaiditi’s Sign in Advanced-Phase Late-Onset Pompe Disease
Authors: Takahashi Junichiro , Mori-Yoshimura Madoka , Ariga Hajime , Sato Noriko , Nishino Ichizo , Takahashi Yuji 
Published: August 2022

Purpose: Chilaiditi’s sign (CS), hepatodiaphragmatic interposition of the intestine, was caused by morphological abnormalities such as diaphragmatic atrophy, intestinal dilation, and liver atrophy. The sign is potentially important due to associations with clinically recurrent abdominal pain or even colonic volvulus. Late-onset Pompe disease (LOPD) could have the high prevalence of CS because of widened hepatodiaphragmatic space, following diaphragmatic atrophy, and the abnormal dilation of intestine caused by glycogen accumulation in smooth muscle of intestine. Our aim was to investigate the prevalence of CS in LOPD, and to identify the risk factors of CS in LOPD patients. Methods: Medical records of genetically confirmed patients of Pompe disease at the National Center Hospital, National Center of Neurology and Psychiatry were retrospectively reviewed. We evaluated CS using chest X-ray (CXR) and abdominal CT and assessed the prevalence of CS in LOPD patients. We also divided the patients into two groups, CS and non-CS group, and evaluated the factor associated with CS compared to clinical variables between groups. Results: Three of seven (43%) were detected in CS. CS group (P5-7) and non-CS group (P1-4) were obtained. In comparison of clinical variables, the severity of atrophy in right diaphragms was significantly higher in CS than non-CS groups ( p = 0.029). Also, the frequency of abnormal position of right diaphragm and liver, and abnormally dilated bowel was seen in all of CS patients, but none of non-CS patient ( p = 0.029, each). Conclusion: In LOPD patients, the prevalence of CS was much higher of 43%, compared to healthy groups, or even in similarly respiratory muscle impaired neuromuscular diseases. The anatomically abnormal position of diaphragm and liver, atrophy and fat infiltration of diaphragms, and abnormally dilated bowel were significantly associated with CS in LOPD. We should pay more attention to CXR or abdominal CT as follow up in LOPD patients.

Background: In advanced Parkinson’s disease (PD), dyskinesias and non-motor symptoms such as sleep dysfunction can significantly impair quality of life, and high-quality management is an unmet need. Objective: To analyze changes in dyskinesia and non-motor symptoms (including sleep) among studies with levodopa-carbidopa intestinal gel (LCIG) in patients with advanced PD. Methods: A comprehensive literature review identified relevant studies examining LCIG efficacy. Outcomes of interest were dyskinesia (UDysRS, UPDRS IV item 32), overall non-motor symptoms (NMSS), mentation/behavior/mood (UPDRS I), and sleep/daytime sleepiness (PDSS-2, ESS). The pooled mean (95% confidence interval) change from baseline per outcome was estimated for each 3-month interval with sufficient data (i.e., reported by≥3 studies) up to 24 months using a random-effects model. Results: Seventeen open-label studies evaluating 1243 patients with advanced PD were included. All outcomes of interest with sufficient data for meta-analysis showed statistically significant improvement within 6 months of starting LCIG. There were statistically significant improvements in dyskinesia duration as measured by UPDRS IV item 32 at 6 months (–1.10 [–1.69, –0.51] h/day) and 12 months (–1.35 [–2.07, –0.62] h/day). There were statistically and clinically significant improvements in non-motor symptoms as measured by NMSS scores at 3 months (–28.71 [–40.26, –17.15] points). Significant reduction of NMSS burden was maintained through 24 months (–17.61 [–21.52, –13.70] points). UPDRS I scores significantly improved at 3 months (–0.39 [–0.55, –0.22] points). Clinically significant improvements in PDSS-2 and ESS scores were observed at 6 and 12 months in individual studies. Conclusion: Patients with advanced PD receiving LCIG showed significant sustained improvements in the burden of dyskinesia and non-motor symptoms up to 24 months after initiation.

Published: August 2022

Background: Among motor symptoms of Parkinson’s disease (PD), including rigidity and resting tremor, bradykinesia is a mandatory feature to define the parkinsonian syndrome. MDS-UPDRS III is the worldwide reference scale to evaluate the parkinsonian motor impairment, especially bradykinesia. However, MDS-UPDRS III is an agent-based score making reproducible measurements and follow-up challenging. Objective: Using a deep learning approach, we developed a tool to compute an objective score of bradykinesia based on the guidelines of the gold-standard MDS-UPDRS III. Methods: We adapted and applied two deep learning algorithms to detect a two-dimensional (2D) skeleton of the hand composed of 21 predefined points, and transposed it into a three-dimensional (3D) skeleton for a large database of videos of parkinsonian patients performing MDS-UPDRS III protocols acquired in the Movement Disorder unit of Avicenne University Hospital. Results: We developed a 2D and 3D automated analysis tool to study the evolution of several key parameters during the protocol repetitions of the MDS-UPDRS III. Scores from 2D automated analysis showed a significant correlation with gold-standard ratings of MDS-UPDRS III, measured with coefficients of determination for the tapping (0.609) and hand movements (0.701) protocols using decision tree algorithms. The individual correlations of the different parameters measured with MDS-UPDRS III scores carry meaningful information and are consistent with MDS-UPDRS III guidelines. Conclusion: We developed a deep learning-based tool to precisely analyze movement parameters allowing to reliably score bradykinesia for parkinsonian patients in a MDS-UPDRS manner.

Published: August 2022

Downy mildew on impatiens is of great concern throughout Florida. Winters in south Florida provide high humidity paired with cool nights, creating ideal conditions for disease development. Downy mildews are caused by several different species of pathogens that tend to be plant-host specific. Plasmopara obducens is the pathogen that affects impatiens. Some literature indicates that nighttime temperatures of about 50 to 72°F favor downy mildew, but the disease has been reported on impatiens year-round in south Florida. This 4-page fact sheet was written by L. Sanagorski (Warner), B. Schall, A.J. Palmateer, and N.A. Peres, and published by the UF Department of Plant Pathology, October 2013.
